Trends of gastric malignancies: Case study of Ibn Sina Hospital 2010-2011

Back ground: Gastric malignancies carry poor prognosis, because they commonly present at an advanced stage.Objective: to find out mode of presentation and its impact on the outcome and management of gastric cancer and to find if there are changes in trends of gastric malignancies over the last decade.Patients and methods: A review of 53 patients with gastric malignancies, treated at Ibn Sina Hospital from August 2010 through August 2011. Their demographic data, pattern of clinical presentation, histopathology grading and staging, type of management and hospital mortality were studied.Statistical analysis: Data was fed to Statistical Package for Social Sciences. Means and correlations were computed where appropriate. One sample t-test was performed. Statistical significance was taken at P = 0.05.Results: Out of 53 patients males comprise 30(56.6%) males. The peak frequency was at the age group 55-70 years. Patients from the Northern Region of Sudan constituted 34%. Adenocarcinoma comprised 43(81.3%), GIST 8(15%), lymphoma 1(1.9%) and carcinoid 1(1.9%). Epigastric painwas the commonest symptom in 47(88.7%) patients. Smoking and snuff (Tombak) and high salt diet were found in 7.5% and 5.7% and 3.8% patients respectively. Blood group A and O was found in 22.6% and 60.4% respectively. Family cancer syndrome was found in 11.3% patients.Malignancies of the antrum constitute 27(65.85%), cardia 4(9.8%), body 7(17.1%), and whole stomach 3(7.3%) patients. There were only 6.25% clinically early cases. Potentially curative resection was attempted in 31.7%. The mean hospital stay was 12 days.Conclusion: Patients presented at stage III and IV comprise 30 (93.75%) out of 32 carcinoma patients. The hospital morbidity was 13(24.6%) patients and mortality 4(7.5%) patients. When compared with results from same hospital there is improvement in outcome over a decade.Keywords: Adenocarcinoma, lymphoma, carcinoid, dysphagia

The timing of ostomy closure in infants with necrotizing enterocolitis: a systematic review

Item does not contain fulltextPURPOSE: The optimal timing of ostomy closure is a matter of debate. We performed a systematic review of outcomes of early ostomy closure (EC, within 8 weeks) and late ostomy closure (LC, after 8 weeks) in infants with necrotizing enterocolitis. METHODS: PubMed, EMbase, Web-of-Science, and Cinahl were searched for studies that detailed time to ostomy closure, and time to full enteral nutrition (FEN) or complications after ostomy closure. Patients with Hirschsprung's disease or anorectal malformations were excluded. Analysis was performed using SPSS 17 and RevMan 5. RESULTS: Of 778 retrieved articles, 5 met the inclusion criteria. The median score for study quality was 9 [range 8-14 on a scale of 0 to 32 points (Downs and Black, J Epidemiol Community Health 52:377-384, 1998)]. One study described mean time to FEN: 19.1 days after EC (n = 13) versus 7.2 days after LC (n = 24; P = 0.027). Four studies reported complication rates after ostomy closure, complications occurred in 27% of the EC group versus 23% of the LC group. The combined odds ratio (LC vs. EC) was 1.1 [95% CI 0.5, 2.5]. CONCLUSION: Evidence that supports early or late closure is scarce and the published articles are of poor quality. There is no significant difference between EC versus LC in the complication rate. This systematic review supports neither early nor late ostomy closure

Ascorbate Biosynthesis during Early Fruit Development Is the Main Reason for Its Accumulation in Kiwi

Background: Ascorbic acid (AsA) is a unique antioxidant as well as an enzyme cofactor. Although it has multiple roles in plants, it is unclear how its accumulation is controlled at the expression level, especially in sink tissues. Kiwifruit (Actinidia) is well-known for its high ascorbate content. Our objective was to determine whether AsA accumulates in the fruits primarily through biosynthesis or because it is imported from the foliage. Methodology/Principal Findings: We systematically investigated AsA levels, biosynthetic capacity, and mRNA expression of genes involved in AsA biosynthesis in kiwi (A. deliciosa cv. Qinmei). Recycling and AsA localization were also monitored during fruit development and among different tissue types. Over time, the amount of AsA, with its capacity for higher biosynthesis and lower recycling, peaked at 30 days after anthesis (DAA), and then decreased markedly up to 60 DAA before declining more slowly. Expression of key genes showed similar patterns of change, except for L-galactono-1,4-lactone dehydrogenase and L-galactose-1-phosphate phosphatase (GPP). However, GPP had good correlation with the rate of AsA accumulation. The expression of these genes could be detected in phloem of stem as well as petiole of leaf and fruit. Additionally, fruit petioles had greater ascorbate amounts, although that was the site of lowest expression by most genes. Fruit microtubule tissues also had higher AsA. However, exogenous applications of AsA to those petioles did not lead to its transport into fruits, and distribution of ascorbate was cell-specific in the fruits, with more accumulation occurring in large

Host Determinants of Reinfection with Schistosomes in Humans: A Systematic Review and Meta-analysis

Background: Schistosomiasis is still a major public health burden in the tropics and subtropics. Although there is an effective chemotherapy (Praziquantel) for this disease, reinfection occurs rapidly after mass drug administration (MDA). Because the entire population do not get reinfected at the same rate, it is possible that host factors may play a dominant role in determining resistance or susceptibility to reinfection with schistosomes. Here, we systematically reviewed and meta-analyzed studies that reported associations between reinfection with the principal human-infecting species (S. mansoni, S. japonicum and S. haematobium) and host socio-demographic, epidemiological, immunological and genetic factors.Methodology/Principal Findings: PubMed, Scopus, Google Scholar, Cochrane Review Library and African Journals Online public databases were searched in October 2013 to retrieve studies assessing association of host factors with reinfection with schistosomes. Meta-analysis was performed to generate pooled odds ratios and standardized mean differences as overall effect estimates for dichotomous and continuous variables, respectively. Quality assessment of included studies, heterogeneity between studies and publication bias were also assessed. Out of the initial 2739 records, 109 studies were included in the analyses, of which only 32 studies with 37 data sets were eligible for quantitative data synthesis. Among several host factors identified, strong positive association was found with age and pre-treatment intensity, and only slightly for gender. These factors are major determinants of exposure and disease transmission. Significant positive association was found with anti-SWA IgG4 level, and a negative overall effect for association with IgE levels. This reconfirmed the concept that IgE/IgG4 balance is a major determinant of protective immunity against schistosomiasis. Other identified determinants were reported by a small number of studies to enable interpretation.Conclusions: Our data contribute to the understanding of host-parasite interaction as it affects reinfection, and is a potential tool to guide planning and tailoring of community interventions to target high-risk groups

Single high scrotal incision orchidopexy for unilateral palpable testis: A randomised controlled study

Background: Bianchi and Squire introduced single high trans-scrotal incision for mobilisation of palpable undescended testes to decrease the potential morbidity of the traditional inguinal approach. This incision has not gained widespread acceptance and there is still a considerable debate about its efficacy. This study evaluated the outcome of high single scrotal incision in comparison to the classic inguinal exploration for unilateral palpable testes regardless to its pre-operative location to assure its validity and safety.Patients and Methods: This was a randomised controlled study conducted on seventy males with palpable unilateral undescended testicles from  November 2009 to October 2013. They were divided into two equal groups; group I had high single scrotal incision and group II had the classic inguinal approach. The comparative parameters between both groups were the operative time, intra-and post-operative complications, postoperativepain and scar.Results: There was statistical significant difference between both groups regarding the operative time (P < 0.001). The high scrotal approach (Group I) was not completed in three cases and were converted to the classic inguinal approach. No statistical significant difference between both groups regarding the post-operative complications. Conclusions: Single high scrotal incision orchidopexy for palpable  undescended testis is safe, has shorter operative time but may not besuitable for proximally lying testis.Key words: Scrotal orchidopexy, palpable undescended testes, single scrotal incisio

The use of Proceed mesh in ventral hernias: A pilot study on 22 cases

Background: The management of major omphalocoele and large incisional hernias is a common problem and constitutes a great challenge for paediatric surgeons. In most cases, the abdominal cavity is so small and does not allow immediate reduction. Prosthetic materials are becoming increasingly popular for such repair, but direct contact between the bowel and these synthetic materials carries the risk of adhesions and intestinal obstruction. The relatively new PROCEED mesh with absorbable layer in contact with the bowel and another polypropylene non-absorbable layer against the abdominal wall may not produce such adhesions. The aim of this study is to evaluate the feasibility and outcome of this relatively new prosthetic mesh for repair of ventral hernia. Patients and Methods: Between June 2009 and December 2012, a pilot study was conducted on 22 cases with large ventral hernias subjected to open surgical repair using PROCEED mesh. The inclusion criterion was cases with large ventral hernias (>4 cm). The evaluating parameters were all the early and late postoperative complications. Results: The defect size ranged from 5 to 12 cm. The early postoperative complication (≤1 month) was seroma discharged from the wound in four cases, while the late complications were recurrent herniation and stitch sinus that occurred in three cases. No manifestations of intestinal obstruction, enterocutaneous fi stula or mortality were encountered in any of the 22 cases. Conclusion: The use of PROCEED composite mesh in ventral hernias is feasible and has minimal complication rates.Key words: Composite mesh, proceed, ventral hernia repai
