Isolation was made from the periphery of the rotted tuber tissues, followed by a pathogenicity test and identification of isolates. Three fungi associated with D. rotundata (white yam) were isolated;they include Penicillium oxalicum, Aspergillus niger and Rhizopus stolonifer. Each of the isolates from pure cultures were inoculated on the head, middle and tail regions of healthy yam tubers. The three fungi were found to be pathogenic at different rates at the head, middle and tail ends of the yam tuber respectively. The head region was less susceptible to the three fungi with the following rot depths (P. oxalicum 25 mma, A. niger 18.2 mma and R. stolenifer 12.7 mmb). Rot depth in the middle region was (P. oxalicum 15 mma, A. niger 10.6 mma and R. stolenifer 8.8 mmb). While the tail region of the yam tuber recorded rot depth of (P. oxalicum 32.0 mma, A. niger 26.4 mma and R. stolenifer 20.8 mmb) respectively. Generally, the tail region of D. rotundata was more susceptible to fungal attack and the rot recorded in the tail region was significantly different from rot at the middle and the head. It was recommended that yam tubers should be stacked with their head on the ground to reduce incidence of rotting in stock-piled yam tubers.展开更多

Whilst these procedures are mandatory for malignant tumors, they seem to be too extensive for benign or border-line tumors, especially in patients with a long life expectancy. In recent years, there has been a growing interest in parenchyma-sparing pancreatic surgery with the aim of achieving better functional results without compromising oncological radicality in patients with benign, border-line or low-grade malignant tumors. Several limited resections have been introduced for isolated or multiple pancreatic lesions, depending on the location of the tumor: central pancreatectomy, duodenum-preserving pancreatic head resection with or without segmental duodenectomy, inferior head resection, dorsal pancreatectomy, excavation of the pancreatic head, middle-preserving pancreatectomy, and other multiple segmental resections. All these procedures are technically feasible in experienced hands,with very low mortality, although with high morbidity rate when compared to standard procedures. Pancreatic endocrine and exocrine function is better preserved with good quality of life in most of the patients, and tumor recurrence is uncommon. Careful patient selection and expertise in pancreatic surgery are crucial to achieve the best results.展开更多
