OP poses diagnostic and therapeutic challenges due to its often-asymptomatic progression and nonspecific clinical presentation. We report the case of a 32-year-old primiparous woman diagnosed with an ovarian pregnancy by ultrasound. The patient frequently used emergency contraceptives and presented with intermittent pelvic pain and secondary amenorrhea with positive urinary β-HCG tests. Ultrasound revealed a lateral uterine gestational sac attached to the left ovary, containing a living fetus of 15 weeks + 6 days, with moderate fluid accumulation. Upon admission, the patient was in shock with severe anemia and hemoperitoneum, necessitating emergency laparotomy. The laparotomy revealed a hemoperitoneum of 1400 mL and a hyper vascularized mass involving the left ovary, requiring left adnexectomy. The mass contained a deceased male fetus of 16 weeks. This case highlights the need for heightened vigilance and precise diagnostic and therapeutic approaches for rare forms of EP to prevent severe complications.展开更多

Method: This was an analytical cross-sectional study with prospective data collection over a 4-month period, from June 10 to October 10, 2020. Patients from precarious security areas were compared to those from safer areas. The Chi squared and Fisher tests were used for comparison of variables. Results: Obstetric emergencies accounted for 38.62% of admissions, from which 25.59% came from precarious security zones. Age was similar in both comparison groups. However, patients from unsafe areas were more likely to reside in rural areas (p 0.001) and more likely to be in unpaid occupations (p 0.001). Prenatal visits were less frequent (p 0.01) and women were more often multigravidae (p 0.01) in the precarious security group of patients. Apart from the more frequent uterine rupture (p = 0.02) in the group from precarious security zones, diagnosed complications and maternal mortality were similar in the 2 groups, while perinatal mortality was higher in the group of patients from precarious security zones (p 0.01). Conclusion: The precarious security situation has negative consequences on maternal and perinatal morbidity and mortality. Further studies are needed for better understanding of these consequences, and improvement of health system resilience strategies, to reduce related maternal and fetal morbidity and mortality.展开更多

In recent years, CPE of type OXA-48 (Ambler class D) have been identified in Dakar. The aim of this study was to evaluate the phenotypic detection of OXA-48 CPE using a temocillin disc (30 μg). Methodology: A retrospective study was carried out at Medical Biology Laboratory of Pasteur Institute in Dakar on Ertapenem-Resistant Enterobacterales (ERE) strains isolated from 2015 to 2017. These strains were then tested with a 30 μg temocillin disc. Any strain resistant to temocillin (inhibition diameter Results: Forty-one ERE isolated during the study period were tested, of which 34 (82.9%) were OXA-48 based on phenotypic detection using temocillin disc and confirmed by PCR (100%). OXA-48 CPE strains detected were composed of Klebsiella pneumoniae (n = 14;41.2%), Enterobacter cloacae (n = 8;23.5%), Escherichia coli (n = 7, 20.5%), Citrobacter freundii (n = 3;8.8%), Cronobacter sakazakii (n = 1;3%) and Morganella morganii (n = 1;3%). Conclusion: Temocillin resistance has a good positive predictive value for detecting OXA-48 CPE by phenotypic method, confirmed by PCR. Temocillin is therefore a good marker for detection of OXA-48 CPE except Hafnia alvei.展开更多

Among these ESBLs, there are the Muenchen Cefotaximase (CTX-M) described all over the world of which the most frequent is the CTX-M of group 1 particularly the CTX-M-15 variant. The objective of this study was to determine the prevalence of CTX-M group 1 ESBL-producing Escherichia coli strains and to test their antibiotics susceptibility profile. Methodology: A retrospective cross-sectional descriptive study was conducted to detect ESBL-secreting Escherichia coli strains by the synergy test. Identification of CTX-M type ESBL from group 1 was performed using the NG-Test CTX-M rapid diagnostic test (NG-Biotech®). Antibiotic susceptibility profile was determined using CA-SFM/EUCAST guidelines 2019. Data entry and statistical analysis were performed with Excel version 2010 and SPSS 20.0 respectively. Results: Eighty-two ESBL-producing Escherichia coli strains were tested. A group 1 CTX-M ESBL was detected in 75.6% of the strains (n = 62). These strains were highly resistant to cefotaxim (100%), aztreonam (100%), ceftazidim (85.4%) and cefepim (66.1%). They were also resistant to quinolones, gentamycin and sulfadoxine-trimethoprim combination. However, these strains showed sensitivity to ertapenem (100%), cefoxitin (69.3%), tigecyclin (66%), and amikacin (66.1%). The combination of piperacillin and tazobactam was active on 30.6% of the strains against 6.4% for the combination of amoxicillin and clavulanic acid. Conclusion: The CTX-M type ESBL of group 1 was present in the majority of ESBL-producing Escherichia colis trains. Despite the production of this enzyme conferring resistance to most beta-lactam antibiotics, some antibiotics remain active to treat infections caused by these germs.展开更多

Material and Methods: This is a prospective, descriptive, cross-sectional study lasting six (6) months, from July 1, 2022 to December 31, 2022. Patients with BPH on comorbidity condition taken care of during the study period AND have agreed to participate in the study. Results: During our study, 49 cases of benign prostatic hypertrophy with comorbidities were collected, representing a frequency of 29%. The average age ranges for the patients were 43 - 70 years. The age group most affected was 70 to 79 years old (38.80%). Nocturnal urinary frequency was the main reason for consultation present in all our patients. The most frequent comorbidity was hypertension, i.e. 83.70%. The PSA rate between 4 and 10 was the most represented, i.e. 42.86%. The prostate volume was between 61 and 100 ml in 40.82% of patients. Histology showed that it was a benign adenomatous hypertrophy of the prostate in 85.70% and a prostatic adenomyoma in 14.29%. Trans-bladder adenomectomy alone was the most performed technique, i.e. 49%, followed by trans urethral resection of the prostate, i.e. 38.80%. Retention of urine after removal of the catheter was the most observed complication, i.e. 12.20%. Conclusion: Benign prostatic hypertrophy with comorbidities constitutes a frequent association. Because their presence can affect effectiveness and lead to complications.展开更多

Methodology: This was a prospective multi-operator analytical study lasting 6 months. It included 70 patients operated on for benign prostatic hypertrophy (BPH), divided into 2 groups of 35 according to the retropubic or transvesical technique. The data was collected using a questionnaire and entered into the Epi info application. The analysis was initially descriptive and then univariate. To identify confounding factors, a multivariate analysis was performed. The application conditions of each test were checked before their application. A p-value Results: Upper adenomectomies represented 53.6% of surgeries performed for BPH. The average age was 73.2 years. The mean prostate volume was 117 ± 51.6 cc and the mean total PSA was 9.2 ± 11.4 ng/ml. The majority of patients had an ASA1 (60%) and ASA2 (37.1%) score. Spinal anesthesia, a double-current silicone probe with hinged hinge 22, and drainage of the prevesical space were carried out in all patients, i.e. 100%. The average overall blood loss was 229 ± 98.2 ml. It was lower in the group of patients operated via the retropubic route (187 ± 60.4 ml). The same was true for the duration of intervention (49.1 ± 7.17 vs 55.4 ± 7.9 min), the catheter wearing time (5.14 ± 0.97 vs 9.29 ± 2 .9 days) and the length of hospitalization (=6.26 ± 1.15 vs 12.1 ± 5.74 days). Conclusion: The retropubic technique has advantages over the transvesical one. These advantages are translated by a gain in the duration of the intervention, blood loss, catheter wearing time and length of hospitalization.展开更多

The objective of this study was to evaluate the influence of prostate weight on the morbidity and mortality of transvesical prostatectomy for adenoma in the urology-andrology department of the Ignace Deen National Hospital. Materials and Methods: This was a prospective, longitudinal and analytical study lasting 6 months, from March 1, 2022 to August 31, 2022 including patients admitted and operated on by open transvesical prostatectomy by assessing the influence of prostate weight on the morbidity and mortality of transvesical adenomectomies. Results: 108 patients were included in our study, the average age of our patients was 70 ± 7.7 years, cultivators were the most represented profession with 38.89%, and hypertension was the most represented comorbidity with 75%. 33.06% of cases became complicated and surgical wound infection was the main complication with a frequency of 17.40%. Statistical analysis did not conclude that, the prostate weight does not have a statistically significant influence on the morbidity and mortality of transvesical open prostatectomy for benign prostatic hyperplasia. Conclusion: Prostate weight has no influence on the morbidity and mortality of transvesical prostate adenoma.展开更多

The severity of these injuries varies according to the age of the child, the type of road user and whether or not protective devices are used. The aim of this study was to carry out a census of admissions and to identify the epidemiological and clinical profile of children involved in road traffic accidents at Donka National Hospital. Methods: This is a descriptive cross-sectional study of children involved in traffic accidents over a 3-month period from September 1 to November 30, 2021. All children admitted to the emergency department for a traffic accident were included in the study. Results: During the study period, 435/530 children (82.1%) were victims of road accidents. Boys accounted for 54.94% of cases, compared with 45.06% for girls. The age group most affected was 12-17 years old (48.97%). October had the highest accident rate (36.4%). Pedestrians are most affected (52.87%). Bicycles and mopeds were involved in 59.77% of accidents. Head injury was the most frequent pathology (33.33%). The study showed that 12.64% of victims were referred to intensive care, pediatric surgery, etc. We recorded 8 cases of death (1.84%). Conclusion: This study highlighted the characteristics, incidence and risk factors for accidents in children admitted to emergency departments. Accident prevention, particularly serious accidents in children, requires more precise knowledge of the factors and circumstances leading to their occurrence.展开更多

Restoring the normal anatomy of the groin region is one of the most benign interventions. However, uro-andrological complications are possible. This study aimed to contribute to the improvement of the management of urogenital complications of groin hernia surgery. Patients and Method: We carried out a prospective study of descriptive type with a duration of 6 months from 1 August 2021 to 31 January 2022. The data were collected using a pre-established survey sheet. The study covered several sites (public hospitals and private clinics) in Guinea. Results: The urogenital complications of the surgery of the hernia of the groin represented 15.22% or 14 cases out of 92 patients. The average age was 37.00 years with extremes of 20-69 years. Polygamists occupied the first place. The reason for consultation was dominated by decreased testicular volume (42.86%), followed by a desire to conceive (21.43%). Unilateral testicular atrophy represented 63.64%, bilateral 27.27%. We performed a left orchidectomy in one patient and a cystorraphy in another simple operative follow-up. The other cases consisting of testicular atrophy, due to lack of a suitable technical platform, did not benefit from any specific therapeutic treatment. Conclusion: Urogenital complications of groin hernia surgery are relatively common. Testicular atrophy was the main clinical complication. The left orchidectomy and cystorraphy were the therapeutic procedures performed.展开更多

Patients and method: It is a prospective study of a descriptive type covering a period of 6 months. The study covered 17 patients, all received for a desire to conceive after at least one year of regular sexual intercourse without contraception. The data were collected from patient interviews using a pre-established questionnaire. Results: The average age of the patients was 32.07 years with extremes of 23 years and 42 years. During this study, 64.70% of patients were no longer participating in community ceremonies. The patients’ relationships with their spouse and family deteriorated in 52.94% and 47.06%, respectively. Conversely, relations with the family of origin remained unchanged in 70.59 percent of cases. The reduction in economic activity was by 13 patients (76.48%). Conclusion: Male infertility causes a real psychic earthquake in men with its corollaries of negative feelings. The rather complex moral repercussions of male infertility affect not only the individual, his/her partner, and family, but also economic activity.展开更多

The popularization of ultrasound in urological practice has contributed to changing habits by making the procedures safer and more effective. The objective of this work was to study the technical aspects, indications and results of minimally invasive urological procedures guided by ultrasound. Material and methods: This was a prospective descriptive study lasting 1 year from January to December 2023 at the Médicis clinic in Conakry. Results: We carried out 126 ultrasound-guided urological interventions in one year, including 6 percutaneous nephrostomies (NPC), one renal cyst puncture-aspiration-sclerotherapy, 102 prostate biopsies, 5 drainages by transrectal aspiration of prostatic abscesses, 10 placements of cystostomy probes. Suprapubic, 2 puncture-aspiration-sclerotherapies for vaginal hydroceles. The average age of our patients was 69 years and the predominant age range was 61 - 70. The majority of our patients were male (97.61%) with a sex ratio of 41 men to one woman. Ultrasound-guided urological interventions were for diagnostic purposes (80.95%), for therapeutic purposes (15.77%) and for diagnostic and therapeutic purposes (3.96%). The indications for ultrasound-guided urological interventions were dominated by prostate pathologies (84.91%). The majority of interventions were performed rectally (84.92%) versus (13.43%) abdominally and only 1.58% scrotalally. All procedures were performed in B-ultrasound mode under local anesthesia and on an outpatient basis. For therapeutic interventions, the patients were seen again one month after the procedure, the clinical examination and ultrasound control found the evolution to be favorable. Conclusion: ultrasound is useful in urological practice for guiding minimally invasive interventions. The indications for ultrasound-guided procedures in urology are dominated by prostate pathologies. These procedures are safe and effective with fewer complications. Interv展开更多

Identifying the formations present in our subsoil is therefore essential for mining recovery. It is in this context that we conducted studies on the formations present in the locality of Guintéguéla. It is located in the northwest of Côte d’Ivoire in the bafing region. The aim of this work was to determine the petrographic and structural characteristics of the formations of the area. The methodology began with documentation and then followed petrography and structural analysis work on the macroscopic and microscopic levels. We observed six groups of rocks: granitoids, amphibolites, orthogneiss, quartzites (poor and rich in magnetites), volcano-sediments and filonian rocks. Metamorphism is of amphibolite to granulite facies. However, volcano-sediments must be associated with the green schist facies. With regard to the structural, structures and microstructures such as foliation;fractures;sigmoidal figures reveal that the studied area was affected by ductile and also brittle tectonics whose main directions are oriented along the shear corridor, so N-S to NNW-SSE.展开更多

The aim of this study was to analyze the management of spermatic cord torsion in the Urology Andrology Department of the Ignace Deen National Hospital in Conakry. Material and methods: This was a ten-year retrospective descriptive study from January 1, 2012 to December 31, 2021. It involved all patients admitted for torsion of the spermatic cord, confirmed at surgical exploration. Results: We identified 21 cases of torsion of the spermatic cord. The mean age of the patients was 17.9 ± 4.4 years. The average consultation time was 19.2 ± 21.4 hours with extremes of [2 h and 98 h]. Only 6 patients (28.6%) consulted before the sixth hour. All patients presented with scrotal swelling. At scrototomy, all torsions were intravaginal with two turns of spiral in 13 cases and three turns in 8 cases. Orchiectomy followed by contralateral orchidopexy was performed in 6 cases. In the other cases, bilateral orchidopexy was performed after detorsion. The average hospital stay was 4.5 days. We recorded 4 cases of testicular atrophy after orchidopexy. Conclusion: Spermatic cord torsion is an infrequent emergency in our department. The delay in consultation remains the main predictive factor of testicular necrosis. Emergency exploratory scrotomy should be the rule.展开更多

Patients and Method: This was a dynamic, descriptive study lasting six months from July 1 to December 31, 2017. Results: Urological emergencies represented 45.14% (n = 218) of all admissions to the urology unit. The mean age of our patients was 56.60 years with extremes of fifteen days and 93 years. The 71 - 80 age group was the most represented with 28.03% (n = 61) followed by 61 - 70 years with 24.31% (n = 53). Our patients’ activities were dominated by agriculture, with 35.77% (n = 88), and the city center was most affected by urological emergencies, with 39.44% of cases (n = 86). 70.18% (n = 153) of our patients had bladder retention on admission, and 53.21% (n = 116) underwent urethral catheterization, including 3 women. The etiology of bladder retention in these 3 women was dominated by two cases of bladder lithiasis and one case of neurological bladder. Conclusion: The management of urological emergencies requires specific material and human resources. Their knowledge will enable us to better understand this problem and could serve as a basis for a broad reflection on the organization of the management of urological emergencies in our region.展开更多

Objective: To improve the state of knowledge on the profile of the infertile man in Guinea. Methodology: We conducted a prospective, descriptive study over a period of 6 months from October 1st, 2020 to March 31st, 2021. Results: We collected an overall number of 71 patients seen onroutine consultation for infertility. They had a mean age of 36.4 years. More than half of our patients were monogamous (79% of cases). Civil servants were the most affected with 38.02% of cases. Primary infertility was dominant in 65% (n = 46) of cases. On clinical examination, varicocele was the most remarkable abnormality with 88.73% (n = 63) followed by testicular hypotrophy with 59.15% (n = 42). Azoospermia was the most frequent sperm abnormality with 22.54% (n = 16) followed by oligospermia with 15.49% (n = 11). Hormonal assessment based on FSH and LH was performed in 16 patients with azoospermia (22.53%). FSH elevation was associated with azoospermia in 6 patients, i.e. 8.45%, azoospermia associated with a normal FSH level accounting for 14.08% in our series. Conclusion: In our practice, male infertility is becoming more and more of a concern due to the increasing number of patients seeking treatment. The scarcity of a medical assistance for procreation unit alongside with more efficient diagnostic means constitutes a handicap for its management.展开更多

Case presentation: This was a 62-year-old patient who had consulted for fistulized lesions of the scrotum associated with urinary disorders. Physical examination found budding lesions in the scrotum from which mucus was leaking. The diagnostic assessment carried out consisted of a biopsy sample of the scrotal lesions, a blood analysis and medical imaging, which led to the diagnosis. The mutilating nature of the surgery proposed to the patient after multidisciplinary consultation meeting and the expensive cost of chemotherapy drugs constituted the limits of the patient’s therapeutic management. Conclusion: Mucinous carcinoma of the scrotum is rare and primary lesion should always be sought. The presence of budding lesions of the scrotum with discharge of mucus should suggest the diagnosis.展开更多

The aim of this study was to contribute to a review of obstetric emergencies at the Labé Regional Hospital maternity unit. Methods: This was a prospective descriptive and analytical study conducted over a period of 6 months in the maternity unit of the Labé Regional Hospital. It concerned all patients admitted to the department for obstetric emergencies. Results: Obstetric emergencies accounted for 20% of obstetric admissions. The mean age of the patients was 25.12 ± 7.15 years, with extremes of 14 and 45 years. The patients were housewives (42.52%), 42.86% did not attend school and 77.41% were from urban areas. The poor were the most numerous (43.52%). The ambulance was the means of transport in only 9% of cases. Acute foetal distress, pre-eclampsia, bony dystocia and post-partum haemorrhage were the most common types of emergency in our series, with frequencies of 27.57%, 22.59%, 17.94% and 10.63% respectively. The risk factors identified were age, origin, gestational age and the state of the maternal pelvis. Conclusion: Obstetric emergencies are frequent in our study site and represent a major concern for patients, providers and the community alike. In order to reduce the frequency of obstetric emergencies, young girls should be enrolled in school, the legal age for marriage should be respected, quality antenatal care should be provided in basic health facilities, and proper planning and spacing of pregnancies should be implemented.展开更多

This paper presents the simulation results of numerical studies on the heat transfer and thermal performance of a two-phase thermosiphon loop for passive air-conditioning of a house. The fluid considered in this study is methanol, which is compatible with copper and is environmentally friendly. These numerical results show that the temperature at the evaporator wall drops from 23<span style="color:#111111;font-family:Roboto, sans-serif;font-size:16px;white-space:normal;background-color:#FFFFFF;">°</span>C to 13<span style="color:#111111;font-family:Roboto, sans-serif;font-size:16px;white-space:normal;background-color:#FFFFFF;">°</span>C and increases at the condenser. The solar flux density has a strong influence on the condenser temperature. The mass flow rates and masses at the evaporator and condenser increase with temperature. The variation of evaporating and condensing temperature affects the performance of the system. For a constant evaporating and condensing temperature of 2<span style="color:#111111;font-family:Roboto, sans-serif;font-size:16px;white-space:normal;background-color:#FFFFFF;">°</span>C and 29<span style="color:#111111;font-family:Roboto, sans-serif;font-size:16px;white-space:normal;background-color:#FFFFFF;">°</span>C, the COP is 0.77 and 0.84 respectively. With these results, the use of the two-phase thermosyphon loop in air conditioning is possible to obtain a thermal comfort of the occupants acceptable by the standards but with a large exchange surface of the evaporator.展开更多

The objective of this work is to characterize the bauxitic deposit of Limbiko. The methodology consists in collecting samples, and establishing stratigraphic logs, sections and geological maps. The analyses were carried out in the laboratory of the Company des Bauxites de Guinea. Statistical methods were used to process the geochemical data. The study area is characterized by sedimentary formations of the Devonian, in which the dolerites of the Mesozoic were injected. It is on these Devonian and Mesozoic formations that the Limbiko bauxite deposit was developed. The stratigraphic logs show the succession of formations. The parent rock is surmounted by an alteration crust. The petrographic study is based on the bauxitic and transitional zones characterized by ferruginous laterites. Both zones contain some ferriplantite. Mineralogical analysis shows the presence of gibbsite, goethite, alumogoethite, rutile and clay minerals. The geochemical study of the major elements shows that the more the contents of SiO<sub>2</sub>, Fe<sub>2</sub>O<sub>3</sub> decrease, the more the content of Al<sub>2</sub>O<sub>3</sub> increases and those of TiO<sub>2</sub>, Al<sub>2</sub>O<sub>3</sub> increase in the same direction. The PCA confirms the mineralogical results by classifying the samples into clay, bauxite and ferrite.展开更多
文摘Ectopic pregnancy (EP) is a common gynecological emergency, with ovarian pregnancy (OP) being a rare form, representing about 3% of EP cases. OP poses diagnostic and therapeutic challenges due to its often-asymptomatic progression and nonspecific clinical presentation. We report the case of a 32-year-old primiparous woman diagnosed with an ovarian pregnancy by ultrasound. The patient frequently used emergency contraceptives and presented with intermittent pelvic pain and secondary amenorrhea with positive urinary β-HCG tests. Ultrasound revealed a lateral uterine gestational sac attached to the left ovary, containing a living fetus of 15 weeks + 6 days, with moderate fluid accumulation. Upon admission, the patient was in shock with severe anemia and hemoperitoneum, necessitating emergency laparotomy. The laparotomy revealed a hemoperitoneum of 1400 mL and a hyper vascularized mass involving the left ovary, requiring left adnexectomy. The mass contained a deceased male fetus of 16 weeks. This case highlights the need for heightened vigilance and precise diagnostic and therapeutic approaches for rare forms of EP to prevent severe complications.
文摘Introduction: Insecurity can be an obstacle to access to emergency obstetric and newborn care, that is why we proposed to study obstetrical emergencies in Ouahigouya Regional Teaching Hospital, a referral hospital in a region plagued by insecurity linked to armed groups. Method: This was an analytical cross-sectional study with prospective data collection over a 4-month period, from June 10 to October 10, 2020. Patients from precarious security areas were compared to those from safer areas. The Chi squared and Fisher tests were used for comparison of variables. Results: Obstetric emergencies accounted for 38.62% of admissions, from which 25.59% came from precarious security zones. Age was similar in both comparison groups. However, patients from unsafe areas were more likely to reside in rural areas (p 0.001) and more likely to be in unpaid occupations (p 0.001). Prenatal visits were less frequent (p 0.01) and women were more often multigravidae (p 0.01) in the precarious security group of patients. Apart from the more frequent uterine rupture (p = 0.02) in the group from precarious security zones, diagnosed complications and maternal mortality were similar in the 2 groups, while perinatal mortality was higher in the group of patients from precarious security zones (p 0.01). Conclusion: The precarious security situation has negative consequences on maternal and perinatal morbidity and mortality. Further studies are needed for better understanding of these consequences, and improvement of health system resilience strategies, to reduce related maternal and fetal morbidity and mortality.

文摘Background: Nowadays, emergence of Carbapenemase-Producing Enterobacterales (CPE) throughout the world has become a public health problem, especially in countries with limited resources. In recent years, CPE of type OXA-48 (Ambler class D) have been identified in Dakar. The aim of this study was to evaluate the phenotypic detection of OXA-48 CPE using a temocillin disc (30 μg). Methodology: A retrospective study was carried out at Medical Biology Laboratory of Pasteur Institute in Dakar on Ertapenem-Resistant Enterobacterales (ERE) strains isolated from 2015 to 2017. These strains were then tested with a 30 μg temocillin disc. Any strain resistant to temocillin (inhibition diameter Results: Forty-one ERE isolated during the study period were tested, of which 34 (82.9%) were OXA-48 based on phenotypic detection using temocillin disc and confirmed by PCR (100%). OXA-48 CPE strains detected were composed of Klebsiella pneumoniae (n = 14;41.2%), Enterobacter cloacae (n = 8;23.5%), Escherichia coli (n = 7, 20.5%), Citrobacter freundii (n = 3;8.8%), Cronobacter sakazakii (n = 1;3%) and Morganella morganii (n = 1;3%). Conclusion: Temocillin resistance has a good positive predictive value for detecting OXA-48 CPE by phenotypic method, confirmed by PCR. Temocillin is therefore a good marker for detection of OXA-48 CPE except Hafnia alvei.
文摘Background: Extended-spectrum beta-lactamase (ESBL) producing bacteria are a real public health problem, particularly in Africa. Among these ESBLs, there are the Muenchen Cefotaximase (CTX-M) described all over the world of which the most frequent is the CTX-M of group 1 particularly the CTX-M-15 variant. The objective of this study was to determine the prevalence of CTX-M group 1 ESBL-producing Escherichia coli strains and to test their antibiotics susceptibility profile. Methodology: A retrospective cross-sectional descriptive study was conducted to detect ESBL-secreting Escherichia coli strains by the synergy test. Identification of CTX-M type ESBL from group 1 was performed using the NG-Test CTX-M rapid diagnostic test (NG-Biotech®). Antibiotic susceptibility profile was determined using CA-SFM/EUCAST guidelines 2019. Data entry and statistical analysis were performed with Excel version 2010 and SPSS 20.0 respectively. Results: Eighty-two ESBL-producing Escherichia coli strains were tested. A group 1 CTX-M ESBL was detected in 75.6% of the strains (n = 62). These strains were highly resistant to cefotaxim (100%), aztreonam (100%), ceftazidim (85.4%) and cefepim (66.1%). They were also resistant to quinolones, gentamycin and sulfadoxine-trimethoprim combination. However, these strains showed sensitivity to ertapenem (100%), cefoxitin (69.3%), tigecyclin (66%), and amikacin (66.1%). The combination of piperacillin and tazobactam was active on 30.6% of the strains against 6.4% for the combination of amoxicillin and clavulanic acid. Conclusion: The CTX-M type ESBL of group 1 was present in the majority of ESBL-producing Escherichia colis trains. Despite the production of this enzyme conferring resistance to most beta-lactam antibiotics, some antibiotics remain active to treat infections caused by these germs.
文摘Goal: To determine the type of comorbidity and highlight the complications of adenomectomy and comorbidities. Material and Methods: This is a prospective, descriptive, cross-sectional study lasting six (6) months, from July 1, 2022 to December 31, 2022. Patients with BPH on comorbidity condition taken care of during the study period AND have agreed to participate in the study. Results: During our study, 49 cases of benign prostatic hypertrophy with comorbidities were collected, representing a frequency of 29%. The average age ranges for the patients were 43 - 70 years. The age group most affected was 70 to 79 years old (38.80%). Nocturnal urinary frequency was the main reason for consultation present in all our patients. The most frequent comorbidity was hypertension, i.e. 83.70%. The PSA rate between 4 and 10 was the most represented, i.e. 42.86%. The prostate volume was between 61 and 100 ml in 40.82% of patients. Histology showed that it was a benign adenomatous hypertrophy of the prostate in 85.70% and a prostatic adenomyoma in 14.29%. Trans-bladder adenomectomy alone was the most performed technique, i.e. 49%, followed by trans urethral resection of the prostate, i.e. 38.80%. Retention of urine after removal of the catheter was the most observed complication, i.e. 12.20%. Conclusion: Benign prostatic hypertrophy with comorbidities constitutes a frequent association. Because their presence can affect effectiveness and lead to complications.
文摘Objective: To compare the results of transvesical and retropubic prostatic adenomectomies at the Urology-Andrology Department of Conakry University Hospital. Methodology: This was a prospective multi-operator analytical study lasting 6 months. It included 70 patients operated on for benign prostatic hypertrophy (BPH), divided into 2 groups of 35 according to the retropubic or transvesical technique. The data was collected using a questionnaire and entered into the Epi info application. The analysis was initially descriptive and then univariate. To identify confounding factors, a multivariate analysis was performed. The application conditions of each test were checked before their application. A p-value Results: Upper adenomectomies represented 53.6% of surgeries performed for BPH. The average age was 73.2 years. The mean prostate volume was 117 ± 51.6 cc and the mean total PSA was 9.2 ± 11.4 ng/ml. The majority of patients had an ASA1 (60%) and ASA2 (37.1%) score. Spinal anesthesia, a double-current silicone probe with hinged hinge 22, and drainage of the prevesical space were carried out in all patients, i.e. 100%. The average overall blood loss was 229 ± 98.2 ml. It was lower in the group of patients operated via the retropubic route (187 ± 60.4 ml). The same was true for the duration of intervention (49.1 ± 7.17 vs 55.4 ± 7.9 min), the catheter wearing time (5.14 ± 0.97 vs 9.29 ± 2 .9 days) and the length of hospitalization (=6.26 ± 1.15 vs 12.1 ± 5.74 days). Conclusion: The retropubic technique has advantages over the transvesical one. These advantages are translated by a gain in the duration of the intervention, blood loss, catheter wearing time and length of hospitalization.
文摘Introduction: Open transvesical prostatectomy remains today one of the most effective approaches for the management of benign prostatic hyperplasia despite the fact that, this method is associated with multiple complications. The objective of this study was to evaluate the influence of prostate weight on the morbidity and mortality of transvesical prostatectomy for adenoma in the urology-andrology department of the Ignace Deen National Hospital. Materials and Methods: This was a prospective, longitudinal and analytical study lasting 6 months, from March 1, 2022 to August 31, 2022 including patients admitted and operated on by open transvesical prostatectomy by assessing the influence of prostate weight on the morbidity and mortality of transvesical adenomectomies. Results: 108 patients were included in our study, the average age of our patients was 70 ± 7.7 years, cultivators were the most represented profession with 38.89%, and hypertension was the most represented comorbidity with 75%. 33.06% of cases became complicated and surgical wound infection was the main complication with a frequency of 17.40%. Statistical analysis did not conclude that, the prostate weight does not have a statistically significant influence on the morbidity and mortality of transvesical open prostatectomy for benign prostatic hyperplasia. Conclusion: Prostate weight has no influence on the morbidity and mortality of transvesical prostate adenoma.
文摘Introduction: Children involved in road accidents most often suffer head or limb injuries. The severity of these injuries varies according to the age of the child, the type of road user and whether or not protective devices are used. The aim of this study was to carry out a census of admissions and to identify the epidemiological and clinical profile of children involved in road traffic accidents at Donka National Hospital. Methods: This is a descriptive cross-sectional study of children involved in traffic accidents over a 3-month period from September 1 to November 30, 2021. All children admitted to the emergency department for a traffic accident were included in the study. Results: During the study period, 435/530 children (82.1%) were victims of road accidents. Boys accounted for 54.94% of cases, compared with 45.06% for girls. The age group most affected was 12-17 years old (48.97%). October had the highest accident rate (36.4%). Pedestrians are most affected (52.87%). Bicycles and mopeds were involved in 59.77% of accidents. Head injury was the most frequent pathology (33.33%). The study showed that 12.64% of victims were referred to intensive care, pediatric surgery, etc. We recorded 8 cases of death (1.84%). Conclusion: This study highlighted the characteristics, incidence and risk factors for accidents in children admitted to emergency departments. Accident prevention, particularly serious accidents in children, requires more precise knowledge of the factors and circumstances leading to their occurrence.
文摘Context and Objective: Groin hernia is a common pathology in visceral surgery (2nd rank after appendicitis), which affects approximately 4.6% of the African population. Restoring the normal anatomy of the groin region is one of the most benign interventions. However, uro-andrological complications are possible. This study aimed to contribute to the improvement of the management of urogenital complications of groin hernia surgery. Patients and Method: We carried out a prospective study of descriptive type with a duration of 6 months from 1 August 2021 to 31 January 2022. The data were collected using a pre-established survey sheet. The study covered several sites (public hospitals and private clinics) in Guinea. Results: The urogenital complications of the surgery of the hernia of the groin represented 15.22% or 14 cases out of 92 patients. The average age was 37.00 years with extremes of 20-69 years. Polygamists occupied the first place. The reason for consultation was dominated by decreased testicular volume (42.86%), followed by a desire to conceive (21.43%). Unilateral testicular atrophy represented 63.64%, bilateral 27.27%. We performed a left orchidectomy in one patient and a cystorraphy in another simple operative follow-up. The other cases consisting of testicular atrophy, due to lack of a suitable technical platform, did not benefit from any specific therapeutic treatment. Conclusion: Urogenital complications of groin hernia surgery are relatively common. Testicular atrophy was the main clinical complication. The left orchidectomy and cystorraphy were the therapeutic procedures performed.
文摘Objective: Describe the psychosocial aspects of male infertility at the hospital of the Sino-Guinean Friendship. Patients and method: It is a prospective study of a descriptive type covering a period of 6 months. The study covered 17 patients, all received for a desire to conceive after at least one year of regular sexual intercourse without contraception. The data were collected from patient interviews using a pre-established questionnaire. Results: The average age of the patients was 32.07 years with extremes of 23 years and 42 years. During this study, 64.70% of patients were no longer participating in community ceremonies. The patients’ relationships with their spouse and family deteriorated in 52.94% and 47.06%, respectively. Conversely, relations with the family of origin remained unchanged in 70.59 percent of cases. The reduction in economic activity was by 13 patients (76.48%). Conclusion: Male infertility causes a real psychic earthquake in men with its corollaries of negative feelings. The rather complex moral repercussions of male infertility affect not only the individual, his/her partner, and family, but also economic activity.
文摘Introduction: Minimally invasive urological interventions have long been practiced blindly in our context. The popularization of ultrasound in urological practice has contributed to changing habits by making the procedures safer and more effective. The objective of this work was to study the technical aspects, indications and results of minimally invasive urological procedures guided by ultrasound. Material and methods: This was a prospective descriptive study lasting 1 year from January to December 2023 at the Médicis clinic in Conakry. Results: We carried out 126 ultrasound-guided urological interventions in one year, including 6 percutaneous nephrostomies (NPC), one renal cyst puncture-aspiration-sclerotherapy, 102 prostate biopsies, 5 drainages by transrectal aspiration of prostatic abscesses, 10 placements of cystostomy probes. Suprapubic, 2 puncture-aspiration-sclerotherapies for vaginal hydroceles. The average age of our patients was 69 years and the predominant age range was 61 - 70. The majority of our patients were male (97.61%) with a sex ratio of 41 men to one woman. Ultrasound-guided urological interventions were for diagnostic purposes (80.95%), for therapeutic purposes (15.77%) and for diagnostic and therapeutic purposes (3.96%). The indications for ultrasound-guided urological interventions were dominated by prostate pathologies (84.91%). The majority of interventions were performed rectally (84.92%) versus (13.43%) abdominally and only 1.58% scrotalally. All procedures were performed in B-ultrasound mode under local anesthesia and on an outpatient basis. For therapeutic interventions, the patients were seen again one month after the procedure, the clinical examination and ultrasound control found the evolution to be favorable. Conclusion: ultrasound is useful in urological practice for guiding minimally invasive interventions. The indications for ultrasound-guided procedures in urology are dominated by prostate pathologies. These procedures are safe and effective with fewer complications. Interv
文摘Côte d’Ivoire is currently experiencing strong growth in the mining sector. Identifying the formations present in our subsoil is therefore essential for mining recovery. It is in this context that we conducted studies on the formations present in the locality of Guintéguéla. It is located in the northwest of Côte d’Ivoire in the bafing region. The aim of this work was to determine the petrographic and structural characteristics of the formations of the area. The methodology began with documentation and then followed petrography and structural analysis work on the macroscopic and microscopic levels. We observed six groups of rocks: granitoids, amphibolites, orthogneiss, quartzites (poor and rich in magnetites), volcano-sediments and filonian rocks. Metamorphism is of amphibolite to granulite facies. However, volcano-sediments must be associated with the green schist facies. With regard to the structural, structures and microstructures such as foliation;fractures;sigmoidal figures reveal that the studied area was affected by ductile and also brittle tectonics whose main directions are oriented along the shear corridor, so N-S to NNW-SSE.
文摘Introduction: Torsion of the spermatic cord is an emergency whose delay in treatment conditions the functional prognosis of the testicle. The aim of this study was to analyze the management of spermatic cord torsion in the Urology Andrology Department of the Ignace Deen National Hospital in Conakry. Material and methods: This was a ten-year retrospective descriptive study from January 1, 2012 to December 31, 2021. It involved all patients admitted for torsion of the spermatic cord, confirmed at surgical exploration. Results: We identified 21 cases of torsion of the spermatic cord. The mean age of the patients was 17.9 ± 4.4 years. The average consultation time was 19.2 ± 21.4 hours with extremes of [2 h and 98 h]. Only 6 patients (28.6%) consulted before the sixth hour. All patients presented with scrotal swelling. At scrototomy, all torsions were intravaginal with two turns of spiral in 13 cases and three turns in 8 cases. Orchiectomy followed by contralateral orchidopexy was performed in 6 cases. In the other cases, bilateral orchidopexy was performed after detorsion. The average hospital stay was 4.5 days. We recorded 4 cases of testicular atrophy after orchidopexy. Conclusion: Spermatic cord torsion is an infrequent emergency in our department. The delay in consultation remains the main predictive factor of testicular necrosis. Emergency exploratory scrotomy should be the rule.
文摘Aim: To contribute to improving the management of urological emergencies at Labé Regional Hospital. Patients and Method: This was a dynamic, descriptive study lasting six months from July 1 to December 31, 2017. Results: Urological emergencies represented 45.14% (n = 218) of all admissions to the urology unit. The mean age of our patients was 56.60 years with extremes of fifteen days and 93 years. The 71 - 80 age group was the most represented with 28.03% (n = 61) followed by 61 - 70 years with 24.31% (n = 53). Our patients’ activities were dominated by agriculture, with 35.77% (n = 88), and the city center was most affected by urological emergencies, with 39.44% of cases (n = 86). 70.18% (n = 153) of our patients had bladder retention on admission, and 53.21% (n = 116) underwent urethral catheterization, including 3 women. The etiology of bladder retention in these 3 women was dominated by two cases of bladder lithiasis and one case of neurological bladder. Conclusion: The management of urological emergencies requires specific material and human resources. Their knowledge will enable us to better understand this problem and could serve as a basis for a broad reflection on the organization of the management of urological emergencies in our region.
文摘Introduction: Male infertility is defined as the inability of a man to impregnate a woman after 12 months of regular sexual intercourse without contraception. Objective: To improve the state of knowledge on the profile of the infertile man in Guinea. Methodology: We conducted a prospective, descriptive study over a period of 6 months from October 1st, 2020 to March 31st, 2021. Results: We collected an overall number of 71 patients seen onroutine consultation for infertility. They had a mean age of 36.4 years. More than half of our patients were monogamous (79% of cases). Civil servants were the most affected with 38.02% of cases. Primary infertility was dominant in 65% (n = 46) of cases. On clinical examination, varicocele was the most remarkable abnormality with 88.73% (n = 63) followed by testicular hypotrophy with 59.15% (n = 42). Azoospermia was the most frequent sperm abnormality with 22.54% (n = 16) followed by oligospermia with 15.49% (n = 11). Hormonal assessment based on FSH and LH was performed in 16 patients with azoospermia (22.53%). FSH elevation was associated with azoospermia in 6 patients, i.e. 8.45%, azoospermia associated with a normal FSH level accounting for 14.08% in our series. Conclusion: In our practice, male infertility is becoming more and more of a concern due to the increasing number of patients seeking treatment. The scarcity of a medical assistance for procreation unit alongside with more efficient diagnostic means constitutes a handicap for its management.
文摘Aim: This paper aims to report the second case of mucinous carcinoma of the scrotum revealed by scrotal fistulas listed in the literature and highlight the difficulties in the search and difficulties encountered in the management of urogenital cancers in developing countries. Case presentation: This was a 62-year-old patient who had consulted for fistulized lesions of the scrotum associated with urinary disorders. Physical examination found budding lesions in the scrotum from which mucus was leaking. The diagnostic assessment carried out consisted of a biopsy sample of the scrotal lesions, a blood analysis and medical imaging, which led to the diagnosis. The mutilating nature of the surgery proposed to the patient after multidisciplinary consultation meeting and the expensive cost of chemotherapy drugs constituted the limits of the patient’s therapeutic management. Conclusion: Mucinous carcinoma of the scrotum is rare and primary lesion should always be sought. The presence of budding lesions of the scrotum with discharge of mucus should suggest the diagnosis.
文摘Introduction: Obstetric emergencies are clinical situations of a serious nature, often dangerous, which develop unexpectedly, threatening the vital prognosis of the mother and/or foetus in the short term. The aim of this study was to contribute to a review of obstetric emergencies at the Labé Regional Hospital maternity unit. Methods: This was a prospective descriptive and analytical study conducted over a period of 6 months in the maternity unit of the Labé Regional Hospital. It concerned all patients admitted to the department for obstetric emergencies. Results: Obstetric emergencies accounted for 20% of obstetric admissions. The mean age of the patients was 25.12 ± 7.15 years, with extremes of 14 and 45 years. The patients were housewives (42.52%), 42.86% did not attend school and 77.41% were from urban areas. The poor were the most numerous (43.52%). The ambulance was the means of transport in only 9% of cases. Acute foetal distress, pre-eclampsia, bony dystocia and post-partum haemorrhage were the most common types of emergency in our series, with frequencies of 27.57%, 22.59%, 17.94% and 10.63% respectively. The risk factors identified were age, origin, gestational age and the state of the maternal pelvis. Conclusion: Obstetric emergencies are frequent in our study site and represent a major concern for patients, providers and the community alike. In order to reduce the frequency of obstetric emergencies, young girls should be enrolled in school, the legal age for marriage should be respected, quality antenatal care should be provided in basic health facilities, and proper planning and spacing of pregnancies should be implemented.
文摘The two-phase thermosyphon loop is an efficient solution for space cooling. This paper presents the simulation results of numerical studies on the heat transfer and thermal performance of a two-phase thermosiphon loop for passive air-conditioning of a house. The fluid considered in this study is methanol, which is compatible with copper and is environmentally friendly. These numerical results show that the temperature at the evaporator wall drops from 23<span style="color:#111111;font-family:Roboto, sans-serif;font-size:16px;white-space:normal;background-color:#FFFFFF;">°</span>C to 13<span style="color:#111111;font-family:Roboto, sans-serif;font-size:16px;white-space:normal;background-color:#FFFFFF;">°</span>C and increases at the condenser. The solar flux density has a strong influence on the condenser temperature. The mass flow rates and masses at the evaporator and condenser increase with temperature. The variation of evaporating and condensing temperature affects the performance of the system. For a constant evaporating and condensing temperature of 2<span style="color:#111111;font-family:Roboto, sans-serif;font-size:16px;white-space:normal;background-color:#FFFFFF;">°</span>C and 29<span style="color:#111111;font-family:Roboto, sans-serif;font-size:16px;white-space:normal;background-color:#FFFFFF;">°</span>C, the COP is 0.77 and 0.84 respectively. With these results, the use of the two-phase thermosyphon loop in air conditioning is possible to obtain a thermal comfort of the occupants acceptable by the standards but with a large exchange surface of the evaporator.
文摘The increasing demand for Aluminium pushes the miners to multiply the research in order to answer this demand. The objective of this work is to characterize the bauxitic deposit of Limbiko. The methodology consists in collecting samples, and establishing stratigraphic logs, sections and geological maps. The analyses were carried out in the laboratory of the Company des Bauxites de Guinea. Statistical methods were used to process the geochemical data. The study area is characterized by sedimentary formations of the Devonian, in which the dolerites of the Mesozoic were injected. It is on these Devonian and Mesozoic formations that the Limbiko bauxite deposit was developed. The stratigraphic logs show the succession of formations. The parent rock is surmounted by an alteration crust. The petrographic study is based on the bauxitic and transitional zones characterized by ferruginous laterites. Both zones contain some ferriplantite. Mineralogical analysis shows the presence of gibbsite, goethite, alumogoethite, rutile and clay minerals. The geochemical study of the major elements shows that the more the contents of SiO<sub>2</sub>, Fe<sub>2</sub>O<sub>3</sub> decrease, the more the content of Al<sub>2</sub>O<sub>3</sub> increases and those of TiO<sub>2</sub>, Al<sub>2</sub>O<sub>3</sub> increase in the same direction. The PCA confirms the mineralogical results by classifying the samples into clay, bauxite and ferrite.
