Transmesenteric hernia after right nephrectomy: diagnostic and therapeutic management.

Internal abdominal hernias are a rare cause of intestinal obstruction (0.2-0.9%). Transmesenteric hernia is a rare type of internal hernia and usually in adult people is acquired. We report the case of a 44 year-old caucasian female with a small bowel occlusion after right nephrectomy for clear cell renal carcinoma caused by an acquired transmesenteric hernia. We emphasize the role of CT scanning for a prompt diagnosis and a quick surgical treatment in order to avoid intestinal gangrene.

First record of Mugil capurrii (Mugilidae, Perciformes) in the Gulf of Guinea.

Leaping African mullet Mugil capurrii was caught along the Togolese coast in the Gulf of Guinea. This is the first record of this species which usually occurs from Morocco to Guinea Bissau and the southernmost point of its known distribution.

Multiplex 16S rRNA haplotype-specific PCR, a rapid and convenient method for fish species identification: an application to West African Clupeiform larvae.

A multiplex haplotype-specific polymerase chain reaction (MHS-PCR) method was developed, which identified seven Clupeiform species living in the tropical Eastern Atlantic region: Sardinella aurita, Sardinella maderensis, Ethmalosa fimbriata, Sardina pilchardus, Engraulis encrasicholus, Pellonula leonensis and Ilisha africana. 16S rRNA fragments were amplified using a species-specific set of primers, yielding species-specific size fragments, and then separated using agarose gel electrophoresis, enabling direct visual identification of targeted species. This method provides an accurate, easy and rapid tool for identifying species within large Clupeiform samples. It is suitable for investigations on early Clupeiform stages, species and identification in fishery management in the tropical Eastern Atlantic area.
