Restoration of Anal Sphincter Tone by Graciloplasty: A Report of Five Cases

Stool incontinence can be as a result of congenital or acquired anal sphincter problems. It is a devastating state for a patient not to be able to control stools resulting into continued feacal soiling. It reduces an individual to a dejected and depressed person who becomes a social misfit. Hence any procedure that can alleviate this state is normally highly appreciated. Various techniques have been quoted in literature and use of gracilis muscle to form a neosphincter is one of them. Dynamic graciloplasty, is a technique whereby electrodes have been implanted into gracilis muscle and is connected to an implantable pulse generator which provides progressive levels of stimulation to convert the fast twitch, fatigue prone muscle fibres to a slow twitch, fatigue resistant firbres over eight week training period (1,2,3). This has shown improved efficacy over the static graciloplasty (3). In this case report, five patients with stool incontinence from different aetiologies are presented, all having been managed by static graciloplasty and intense physiotherapy with good outcomes reported

<it>TP53 </it>mutations, human papilloma virus DNA and inflammation markers in esophageal squamous cell carcinoma from the Rift Valley, a high-incidence area in Kenya

<p>Abstract</p> <p>Background</p> <p>Squamous Cell Carcinoma of Esophagus is one of the most common malignancies in both men and women in eastern and south-eastern Africa. In Kenya, clinical observations suggest that this cancer is frequent in the Rift Valley area. However, so far, there has been no report on the molecular characteristics of esophageal squamous cell carcinoma (ESCC) in this area.</p> <p>Results</p> <p>We have analyzed <it>TP53 </it>mutations, the presence of human papilloma virus (HPV) DNA and expression of inflammation markers Cyclooxygenase 2 (Cox-2) and Nitrotyrosine (NTyR) in 28 cases (13 males and 15 females) of archived ESCC tissues collected at the Moi Teaching and Referral Hospital in Eldoret, Kenya. Eleven mutations were detected in <it>TP53 </it>exons 5 to 8 (39%). All ESCC samples were negative for HPV 16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 70, 73 and 82. Immunohistochemical analysis of Cox-2 and NTyR showed a low proportion of positive cases (17.4% and 39.1%, respectively). No association between the above markers and suspected risk factors (alcohol or tobacco use, hot tea drinking, use of charcoal for cooking) was found.</p> <p>Conclusion</p> <p>Our findings suggest that mechanisms of esophageal carcinogenesis in eastern Africa might be different from other parts of the world. Low prevalence of <it>TP53 </it>mutation compared with other intermediate or high incidence areas of the world highlights this hypothesis. Our data did not support a possible ole of HPV in this series of cases. Further studies are needed to assess and compare the molecular patterns of ESCC from Kenya with those of high-incidence areas such as China or Central Asia.</p
