Helicobacter pylori (H. pylori) is an important pathogen in the stomach which can cause chronic inflammation, predisposing patients to peptic ulcer disease. It is also a class 1 human carcinogen, increasing the risk of gastric carcinoma. Eradication of H. pylori has been shown to be effective in the prevention of peptic ulcer disease as well as gastric carcinoma. Singapore is an intermediate-risk area for gastric cancer, and the seroprevalence of H. pylori infection is 31 percent. Testing for H. pylori consists of non-invasive tests such as H. pylori serology, stool antigen assay, and the urea breath test, as well as invasive tests requiring oesophago-gastro-duodenoscopy (OGD) and biopsies for the rapid urease test, histology, and cultures. Stool antigen assay represents a more accurate non-invasive outpatient test for H. pylori at slightly increased cost in the primary care setting, as positive H. pylori serology does not necessarily imply active infection. Triple therapy remains an effective first-line eradication treatment in Singapore from studies of H. pylori resistance locally. Treatment failures should be retreated with quadruple therapy or other strategies such as concomitant therapy, hybrid therapy and sequential therapy.

Zambia is one of the HIV high burden countries in Sub Saharan Africa. Government of Zambia has been expanding Antiretroviral Therapy (ART) service nationwide at district level. However, it is still hard to access to ART service for PLHIVs who live in rural. In terms of accessibility, the service must be expanded to rural health centre level, but there are many challenges to expand the quality services into such resource limited setting, especially in the shortage of health providers.
JICA's “Integrated HIV and AIDS Care Implementation Project at District Level” launched at April 2006 to improve the quality and accessibility of HIV and AIDS care services in rural Zambia. Two districts in rural area, namely Mumbwa and Chongwe, were selected as project sites. The Project introduced the “mobile ART service” at rural health centre level using the existing health system. Mobile ART services enable a rural health centre that cannot offer ART by itself to provide ART services through the human resource and technical support/assistance of the District Hospital. Mumbwa and Chongwe District Health Management Team (DHMT) started mobile ART services in the first Quarter of 2007, therefore access to ART service in districts has been improved and contributed to increase of ART clients and reduce the defaulter rate within first 6 months of treatment. The project also tried to introduce the community involvement to overcome the shortage of human resources.
We found that Mobile ART services involving the community are beneficial and effective, and help ART services expansion to rural health facilities where resources are limited, and as close as possible to places where clients live. The strategies we experienced were cited in “the National Mobile HIV Services Guidelines” published by the MoH and will be able to be duplicated in other resource-limited areas of not only Zambia but also other developing countries.

Purpose:
Adreno-muscarinic synergy, a supra-additional contractile response to simultaneous application of α-adrenoreceptor and muscarinic receptor agonists, is a feature of several lower urinary tract regions that have dual sympathetic and parasympathetic innervation. We tested the hypothesis that synergy is also a feature of prostate tissue obtained from men with benign prostatic enlargement.
Methods:
Isolated tissue strips were dissected from prostate ‘chips’, collected after transurethral prostate resection procedures for in vitro experiments, to measure isometric tension at 36°C.
Results:
Added separately to the superfusate, phenylephrine and carbachol generated contractions with mean pEC50 (-log10EC50) values of 5.36 and 5.58, respectively, although phenylephrine maximal responses were about six-fold greater. In the presence of carbachol, the mean phenylephrine pEC50 was significantly increased to 5.84 and maximal response increased by 28%; overall, a significant synergistic response was demonstrated. The synergistic response was reduced by muscarinic receptor antagonists, most potently by the M3-selective agent 4-DAMP (1,1-dimethyl-4-diphenylacetoxypiperidinium iodide), and less so by M2 and M1-selective inhibitors gallamine and pirenzepine, but with an overall profile indicating M3/M2 mediation of the synergistic response. The magnitude of the synergistic response was variable between prostate chips that provided isolated preparations suggesting regional heterogenicity, although their zonal origin could not be determined.
Conclusions
These experiments show that adreno-muscarinic contractile synergy is a feature of human hyperplastic prostate tissue. This has implications for the use of a combination therapy of α-blockers and anti-muscarinic agent to relieve secondary symptoms associated with benign prostatic hyperplasia, at least in men who can tolerate antimuscarinics without a risk of retention.

A systematic review of the literature was undertaken to evaluate the efficacy of medial patellofemoral ligament (MPFL) reconstruction combined with tibial tuberosity transfer (TTT) in the treatment of patellofemoral instability. Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic search was carried out to identify and review the published literature pertinent to MFPL reconstruction combined with TTT. Relevant studies were critically appraised with narrative data synthesis. Studies that met the eligibility criteria were suitable for appraisal and consisted of case series and therapeutic series (levels IV & III). All studies had inherent variations in outcomes reporting and limited follow-up. Combined treatment offers restoration of normal anatomy, thus adding clinical value to the currently recommended anatomic approach to MPFL reconstruction. Nevertheless, the current body of evidence does not determine the threshold at which patellofemoral axis requires the need for adjunctive distal realignment as opposed to MPFL reconstruction alone. This review highlighted numerous recurring limitations in the conduct and presentation of the studies, which inadvertently mitigated the interpretation of their results. Future priority should be awarded to larger randomised controlled trials utilising validated patient reported outcome measures.

BACKGROUND: In cases of total knee arthroplasty (TKA) threatened by potential hardware exposure, flap-based reconstruction is indicated to provide durable coverage. Historically, muscle flaps were favored as they provide vascular tissue to an infected wound bed. However, data comparing the performance of muscle versus fasciocutaneous flaps are limited and reflect a lack of consensus regarding the optimal management of these wounds. The aim of this study was to compare the outcomes of muscle versus fasciocutaneous flaps following the salvage of compromised TKA. METHODS: A systematic search and meta-analysis were performed to identify patients with TKA who underwent either pedicled muscle or fasciocutaneous flap coverage of periprosthetic knee defects. Studies evaluating implant/limb salvage rates, ambulatory function, complications, and donor-site morbidity were included in the comparative analysis. RESULTS: A total of 18 articles, corresponding to 172 flaps (119 muscle flaps and 53 fasciocutaneous flaps) were reviewed. Rates of implant salvage (88.8% vs. 90.1%, P=0.05) and limb salvage (89.8% vs. 100%, P=0.14) were comparable in each cohort. While overall complication rates were similar (47.3% vs. 44%, P=0.78), the rates of persistent infection (16.4% vs. 0%, P=0.14) and recurrent infection (9.1% vs. 4%, P=0.94) tended to be higher in the muscle flap cohort. Notably, functional outcomes and ambulation rates were sparingly reported. CONCLUSIONS: Rates of limb and prosthetic salvage were comparable following muscle or fasciocutaneous flap coverage of compromised TKA. The functional morbidity associated with muscle flap harvest, however, may support the use of fasciocutaneous flaps for coverage of these defects, particularly in young patients and/or high-performance athletes.

Perianeurysmal cysts are a rare and poorly understood finding in patients both with treated and untreated aneurysms. While the prior literature suggests that a minority of perianeurysmal cysts develop 1-4 years following endovascular aneurysm treatment, this updated review demonstrates that nearly half of perianeurysmal cysts were diagnosed following aneurysm coiling, with the other half diagnosed concurrently with an associated aneurysm prior to treatment. 64% of perianeurysmal cysts were surgically decompressed, with a 39% rate of recurrence requiring re-operation. We report a case of a 71-year-old woman who presented with vertigo and nausea and was found to have a 3.4 cm perianeurysmal cyst 20 years after initial endovascular coiling of a ruptured giant ophthalmic aneurysm. The cyst was treated with endoscopic fenestration followed by open fenestration upon recurrence. The case represents the longest latency from initial aneurysm treatment to cyst diagnosis reported in the literature and indicates that the diagnosis of perianeurysmal cyst should remain on the differential even decades after treatment. Based on a case discussion and updated literature review, this report highlights proposed etiologies of development and management strategies for a challenging lesion.
