Plastic and reconstructive surgery in Uganda – 10 years experience

We describe our experience of working in plastic and reconstructive surgery in Uganda over the last 10 years. There is a high burden of disease, a health system that is under resourced, and few qualified physicians to provide healthcare for a principally rural population. Training the physicians of the future is essential. Prevention and early wound management needs to be emphasized for traumatic injuries including burns. Subsidized up-country visits by trained specialists with the appropriate equipment are required to provide a service for the rural poor. There appears to be a high mortality rate in babies with unrepaired cleft palate, probably due to feeding difficulties in an environment where intercurrent illness is common. We now offer nutritional support with early combined cleft lip and palate repair in these babies, a practice that has a high success rate and may be suited to other specialist units in the developing world.     

Short‐ and long‐term outcomes of arterial reconstruction on recipient splenic artery in adult liver transplantation. Single‐center prospective study 25 years after first description

Several techniques have been proposed for liver transplantation with inadequate hepatic artery (HA) anastomosis. We aimed to analyze outcomes of arterial reconstruction with the splenic artery (SA). This was a prospective study of our experience with recipients who underwent arterial anastomosis on the SA compared with patients who underwent standard HA. We included 54 patients in the SA group and 1405 in the HA group. Patients in SA group were more frequently retransplantation (31% vs. 8%; P = 0.001), required more transfusion (11 ± 12 vs. 6 ± 9.9 PRC; P = 0.001), had longer surgeries (424 ± 95 vs. 394 ± 102 min; P = 0.03), and longer hospital stays (28 ± 29 vs. 20 ± 18 days; P = 0.002). There were no differences in vascular and biliary complications (15% and 7%; P = 0.18; and 32% and 23%; P = 0.32), primary dysfunction (11% and 9%; P = 0.74), reoperation (12% and 10%; P = 0.61), postoperative mortality (13% and 7%; P = 0.12) and 5 years survival (66% vs. 63%; P = 0.71). Following primary transplantation, there were no differences. The outcomes of arterial reconstruction using the recipients' SA in adult liver transplantation are comparable to those for standard HA reconstruction after a first transplant.     

The first description of the absence of the palmaris longus muscle

Background: While Realdo Colombo from Cremona, Italy has, to date, been acknowledged to be the first to describe the possible absence of the palmaris longus muscle in men in 1559, the authors found this absence to be recorded in the first edition of “De Humani Corporis Fabrica Libri Septum” by Andreas Vesalius, published in 1543. Method: To commemorate Vesalius’ 500th birthday, this earlier record is quoted and discussed. Results and conclusion: It remains unknown whether the observation on the absence of the palmaris longus was first done by Vesalius or was based on joined work by Vesalius and Colombo.     

Prostate gland volume is a strong predictor of biopsy results in men 70 years or older with prostate-specific antigen levels of 2.0–10.0 ng/mL

PURPOSE: The incidence of prostate cancer, benign prostatic enlargement and serum level of prostate-specific antigen (PSA) increase with patient age. Intermediate elevation of PSA in elderly populations is apt to be considered insignificant. We evaluated the impact of PSA and prostate volume on the presence of non-palpable prostate cancer in elderly men with an intermediate level of PSA. MATERIALS AND METHODS: Clinical records of 154 men 70 years or older, with non-cancerous digital rectal examination findings and with serum PSA levels of 2.0-10.0 ng/mL, who underwent initial 6- to 10-core transrectal prostate biopsy, were reviewed for prostate volume, number of biopsy cores, PSA and associated parameters. Stepwise logistic regression and receiver operating characteristic (ROC) models were used to determine the impacts of the parameters on the biopsy results. RESULTS: Overall cancer detection rate was 40/154 or 26.0%. Prostate-specific antigen showed no significant association with the presence of prostate cancer (P = 0.59, Mann-Whitney U-test), while prostate volume did (P < 0.0001). On stepwise logistic regression analysis, prostate volume (P = 0.024, 95% CI 1.008-1.116) and biopsy core density (P = 0.017, 95% CI 4.76-7.12 x 10(6)) were independently associated with a cancer diagnosis, whereas PSA density was not an independent factor for a positive biopsy result. The area under the ROC curve for prostate volume was significantly superior to that of PSA (0.802 vs. 0.529; P = 0.012). CONCLUSIONS: In men 70 years or older with gray zone PSA, prostate cancer patients are equally distributed over any PSA range. Although PSA has less impact on cancer presence than mere prostate volume, prostate cancer would be detected in a substantial proportion of older patients with PSA levels of 2.0-10.0 ng/mL.     

The association between stressful life events and respiratory infections during the first 4 years of life: The Environmental Determinants of Diabetes in the Young study

The aim of this study was to conduct a prospective analysis of the association between negative life events (NLEs) and respiratory infections in children genetically at risk for islet autoimmunity (IA) and type 1 diabetes (T1D). Long‐ and short‐term temporal associations between NLEs and rate of respiratory infection episodes (RIEs) in 5,618 children in The Environmental Determinants of Diabetes in the Young study for at least 1 up to 4 years were analysed. All models were adjusted for demographic, day care, season of infection, and psychosocial factors associated with the rate of child RIEs between study visits. The rate of child RIEs was 26% higher in Europe (Sweden, Finland, Germany) than in the United States (rate ratio [RR] = 1.26, p < 0.001). However, the percentage of child NLEs (odds ratio [OR] = 1.18, p < 0.001) and mother NLEs (OR = 1.83, p < 0.001) was higher in the United States compared with Europe. In both continents (Europe, RR = 1.12, p < 0.001; United States, RR = 1.07, p = 0.006), high child cumulative NLEs (>1 NLE per year since study inception) was significantly associated with an increased rate of child RIEs. This large‐scale prospective study confirms observations that stress may increase the susceptibility for infections in paediatric populations and suggests at least one mechanism by which stress could increase risk for IA and T1D in genetically at risk children.
