Viral Load, Clinical Disease Severity and Cellular Immune Responses in Primary Varicella Zoster Virus Infection in Sri Lanka
BACKGROUND: In Sri Lanka, varicella zoster virus (VZV) is typically acquired during adulthood with significant associated disease morbidity and mortality. T cells are believed to be important in the control of VZV replication and in the prevention of reactivation. The relationship between viral load, disease severity and cellular immune responses in primary VZV infection has not been well studied. METHODOLOGY: We used IFNgamma ELISpot assays and MHC class II tetramers based on VZV gE and IE63 epitopes, together with quantitative real time PCR assays to compare the frequency and phenotype of specific T cells with virological and clinical outcomes in 34 adult Sri Lankan individuals with primary VZV infection. PRINCIPAL FINDINGS: Viral loads were found to be significantly higher in patients with moderate to severe infection compared to those with mild infection (p<0.001) and were significantly higher in those over 25 years of age (P<0.01). A significant inverse correlation was seen between the viral loads and the ex vivo IFNgamma ELISpot responses of patients (P<0.001, r = -0.85). VZV-specific CD4+ T cells expressed markers of intermediate differentiation and activation. CONCLUSIONS: Overall, these data show that increased clinical severity in Sri Lankan adults with primary VZV infection associates with higher viral load and reduced viral specific T cell responses
Interventions for hyperhidrosis in secondary care : a systematic review and value-of-information analysis
Background: Hyperhidrosis is uncontrollable excessive sweating that occurs at rest, regardless of temperature. The symptoms of hyperhidrosis can significantly affect quality of life. The management of hyperhidrosis is uncertain and variable. Objective: To establish the expected value of undertaking additional research to determine the most effective interventions for the management of refractory primary hyperhidrosis in secondary care. Methods: A systematic review and economic model, including a value-of-information (VOI) analysis. Treatments to be prescribed by dermatologists and minor surgical treatments for hyperhidrosis of the hands, feet and axillae were reviewed; as endoscopic thoracic sympathectomy (ETS) is incontestably an end-of-line treatment, it was not reviewed further. Fifteen databases (e.g. CENTRAL, PubMed and PsycINFO), conference proceedings and trial registers were searched from inception to July 2016. Systematic review methods were followed. Pairwise meta-analyses were conducted for comparisons between botulinum toxin (BTX) injections and placebo for axillary hyperhidrosis, but otherwise, owing to evidence limitations, data were synthesised narratively. A decision-analytic model assessed the cost-effectiveness and VOI of five treatments (iontophoresis, medication, BTX, curettage, ETS) in 64 different sequences for axillary hyperhidrosis only. Results and conclusions: Fifty studies were included in the effectiveness review: 32 randomised controlled trials (RCTs), 17 non-RCTs and one large prospective case series. Most studies were small, rated as having a high risk of bias and poorly reported. The interventions assessed in the review were iontophoresis, BTX, anticholinergic medications, curettage and newer energy-based technologies that damage the sweat gland (e.g. laser, microwave). There is moderate-quality evidence of a large statistically significant effect of BTX on axillary hyperhidrosis symptoms, compared with placebo. There was weak but consistent evidence for iontophoresis for palmar hyperhidrosis. Evidence for other interventions was of low or very low quality. For axillary hyperhidrosis cost-effectiveness results indicated that iontophoresis, BTX, medication, curettage and ETS was the most cost-effective sequence (probability 0.8), with an incremental cost-effectiveness ratio of £9304 per quality-adjusted life-year. Uncertainty associated with study bias was not reflected in the economic results. Patients and clinicians attending an end-of-project workshop were satisfied with the sequence of treatments for axillary hyperhidrosis identified as being cost-effective. All patient advisors considered that the Hyperhidrosis Quality of Life Index was superior to other tools commonly used in hyperhidrosis research for assessing quality of life. Limitations: The evidence for the clinical effectiveness and safety of second-line treatments for primary hyperhidrosis is limited. This meant that there was insufficient evidence to draw conclusions for most interventions assessed and the cost-effectiveness analysis was restricted to hyperhidrosis of the axilla. Future work: Based on anecdotal evidence and inference from evidence for the axillae, participants agreed that a trial of BTX (with anaesthesia) compared with iontophoresis for palmar hyperhidrosis would be most useful. The VOI analysis indicates that further research into the effectiveness of existing medications might be worthwhile, but it is unclear that such trials are of clinical importance. Research that established a robust estimate of the annual incidence of axillary hyperhidrosis in the UK population would reduce the uncertainty in future VOI analyses
Sclerodermie : Rapport de Quatre Cas
Four cases of sclerodermia have been reported durintwo months. Sclerodermia which seems to he hardness of the skin is actually a general affection that first appears on the skin and has various types: edematous, sclerema for children, and then the forms of patches or drops or bands Or annulars. It is sor t of connective tissue affection and is chiefly observed in women and as the reason for it, is thought to be due to the acute infections and chronic toxics in theory dysendocryno- sympathic that eventually is caused by nervous- mental disturbances and shocks."nThree of the pa t ients were adults and one of them was a 60 years old man. Clinical symptoms were common in all three persons and as a usual it began from the fingers and then it appeared in the face, but in the man it was different and the disease began first from the chest and abdomen and buttucks parts, and although the duration of the illness was more than few months it had not yet affected the limbs. After sometime it affects the muscles and bones and in a few years it expands so that causes a general weakness and eventually results in death."nThe treatment is tern porary and differs comparatively in different cases. Vitamin E given with large dosage, Vitamin D2 to keep calcium from running. Bismuth, Penicilline with large dosage and tetracycline given continuously, and at last cortisone and A.C. which have temporary and rapid result

Dermatofibrosarcoma protuberans of the upper lip: An overview and a case report
Dermatofibrosarcoma protuberans is a slow-growing but locally aggressive malignant neoplasm of the skin. The preferential locations are on the trunk and proximal extremities but it can occur in the head and neck region in about 15% of the cases. This is a report of such a case and a review of the literature of head and neck cases attempting to analyse the profile of patients and surgical prognosis factors. The recurrence rate is important (20% to 55%) and dependent on tile free tissue margins. Those margins are at least 3 cm in all directions; this is difficult to assess in the head and neck region because of both functional and cosmetic aspects. Distant metastases are rare but related to a long recurrence history. This behaviour gives the impression that prognosis is poorer for dermatofibrosarcoma in the head and neck than within other locations.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Giant solitary osteochondroma of the proximal humerus treated by resection and fibular autograft reconstruction.
A giant solitary osteochondroma of the proximal humerus in a 9-year-old boy was widely resected. Reconstruction of the bone defect was achieved with two nonvascularized fibula segments which gave sufficient stability to the proximal humerus and yielded rapid bone remodeling into an almost normal cortical bone after six months.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
