Five treatment procedures evaluated for the elimination of ascorbate interference in the enzymatic determination of urinary oxalate

We evaluated the efficacies of five treatment procedures for eliminating ascorbate interference in the enzymatic determination of urinary oxalate. Aliquots of urine samples, containing different amounts of added ascorbate and oxalate, were individually subjected to ferric chloride, sodium nitrite, sodium periodate, charcoal, or ascorbate oxidase treatment to eliminate ascorbate interference. Oxalate contents of the urine samples were then determined by a banana oxalate oxidase-horseradish peroxidase-linked assay with 3-methyl-2-benzothiazolinone hydrazone and 3-(dimethylamino)benzoic acid as chromogens. Only those urine samples treated with ascorbate oxidase or charcoal consistently gave recovery of oxalate close to 100%. Treatment with other reagents, though improving the recovery of oxalate, gave inconsistent results. On the basis of these data, we describe procedures for simply and reliably assaying oxalate by using banana oxalate oxidase.     

Enteric fever: Diagnostic value of clinical features.

Objectives: to evaluate the diagnostic value of clinical symptoms and signs in enteric fever and to propose a clinical diagnostic criterion. Design: Prospective observational study Setting: Kathmandu Medical College, Teaching Hospital, Kathmandu, Nepal Materials and methods: febrile patients with clinical diagnosis of enteric fever were included in the study with the aim of confirming diagnosis with blood culture, or bone marrow culture and evaluating the diagnostic accuracy of various clinical signs and symptoms. Results: 64% of the clinically diagnosed cases had blood/ bone marrow culture positive. The diagnostic accuracy of the various symptoms and signs excluding fever was between 42%-75.5%. Majority of the symptom and sign did not have very high diagnostic accuracy. Hence a diagnostic criterion was proposed and clinical features with diagnostic accuracy more than 50% were taken into consideration. Major criteria included fever with diagnostic accuracy of 64%, headache with accuracy of 75.5% and relative bradycardia with an accuracy of 66%. Minor criteria included vomiting, diarrhoea, Splenomegaly, chills and abdominal pain /discomfort with diagnostic accuracy of 57%, 55%, 55%, 53% and 51% respectively. Finally after combination of various major and minor criteria a final diagnostic criterion was proposed having an accuracy of 66% and including both major and minor clinical symptom and sign. Conclusion: clinical diagnosis of enteric fever will be very helpful in a country like ours. Though none of the clinical symptoms and sign have very high diagnostic accuracy a diagnostic criteria may be helpful. Criteria including both major and minor signs and symptoms would be the most appropriate diagnostic tool as it includes the important abdominal symptoms and signs of enteric fever. Key words: enteric fever, clinical features, diagnostic criteria.     

Boerhaave's syndrome complicating acute myocardial infarction. Case report

A case of spontaneous rupture of the oesophagus (Boerhaave's syndrome) following acute myocardial infarction is presented. Conservative management with chest drainage and parenteral, later jejunostomy, feeding was successful. Progress was monitored with methylene blue swallow. A review of the literature revealed only two previous cases of this type.     

Support to the Safe Motherhood Programme in Nepal: an integrated approach

Evidence gathered from 1997 to 2006 indicates progress in reducing maternal mortality in Nepal, but public health services are still constrained by resource and staff shortages, especially in rural areas. The five-year Support to the Safe Motherhood Programme builds on the experience of the Nepal Safer Motherhood Project (1997-2004). It is working with the Government of Nepal to build capacity to institute a minimum package of essential maternity services, linking evidence-based policy development with health system strengthening. It has supported long-term planning, working towards skilled attendance at every birth, safe blood supplies, staff training, building management capacity, improving monitoring systems and use of process indicators, promoting dialogue between women and providers on quality of care, and increasing equity and access at district level. An incentives scheme finances transport costs to a health facility for all pregnant women and incentives to health workers attending deliveries, with free services and subsidies to facilities in the poorest 25 districts. Despite bureaucracy, frequent transfer of key government staff and political instability, there has been progress in policy development, and public health sector expenditure has increased. For the future, a human resources strategy with career paths that encourage skilled staff to stay in the government service is key.     

A Double-Blind Comparison of Sinusoidal Wave and Brief-Pulse Electroconvulsive Therapy in Endogenous Depression

In a double-blind prospective study, 29 endogenously depressed patients (RDC) were randomized into sinusoidal wave (SW) and brief-pulse (BP) electroconvulsive therapy (ECT) groups. Bilateral modified treatments were administered on alternate days, three per week, and the treatment variables of current dosage and seizure duration were monitored for each treatment. Significantly more patients responded to SW than to BP ECT, but a comparable number of treatments was required to produce this response in the two groups. There was no difference in clinical or treatment variables between the SW and the BP groups, nor between ECT responders and nonresponders, with the exception that the SW-treated patients received larger doses of current per treatment than did the BP patients. For endogenous depression treated with ECT, we conclude that cumulative seizure duration may not be a parameter of significance, that overall rate of recovery in ECT responders is independent of stimulus waveform, and that some depressives may respond to SW but not to BP ECT. We suggest that the antidepressant effect of the ECT seizure may be characterized by a therapeutic window in current requirements; alternatively, a putative response threshold (again in terms of current requirement) may exist, which is higher in some patients than in others.     

Immunogenetic association in patients with antineutrophil cytoplasmic antibodies (ANCA) from Mumbai, Maharashtra, India

Considerable genetic evidence exit for ANCA-associated vasculitis and pathogenesis. HLA A and B alleles identified serologically from 84 ANCA-positive patients were compared with 101 controls. Further subtyping were done in the 27 "pauci-immune" vasculitis patients using the polymerase chain reaction based PCR-SSOP technique and compared with controls (67). The results revealed that HLA A1 (OR=4.00; p value 2.72E-05), B17 (OR=3.38; p value 0.0008) and HLA B40 (OR=2.74; p value 0.001) were significantly increased among ANCA-positive patients when compared with the controls. Further, the molecular subtypes A*0101 (OR=5.04; p value 0.0005), B*5801 (OR=4.47; p value 0.0002) and haplotype A*0101-B*5801 (OR=4.47; p value 0.0001) were significantly increased among the autoimmune patients. The study revealed that HLA A1, B17 and B40 alleles are associated in production of antineutrophil autoantibodies and A*0101-B*5801 haplotype is significantly associated with autoimmune diseases and they may be invariably involved in disease pathogenesis in India.     

Clinicopathological patterns of bladder carcinoma over 1 year: experience from University Hospital of Nepal

Purpose

To define the clinical and pathological patterns of urinary bladder carcinoma from the University Hospital of Nepal.

Methods

This is a retrospective analytical study. Patients with bladder mass who underwent surgery over 1 year and who had data record were included in the study. Demographic profile, type of surgery, findings on clinical examination, cystoscopy findings, histopathological report, tumor stage, and post-surgery adjuvant therapy were analyzed.

Results

Out of 86 patients who underwent transurethral resection of bladder tumor, 77 patients had biopsy-proven malignant bladder tumor. Urothelial cancer was present in 96.1%. Male were 78.6%. The mean age of diagnosis was 65.5?±?11.8 years. Non-muscle-invasive bladder cancer (NMIBC) was 3.7 times more common than muscle-invasive bladder cancer (MIBC). High-grade tumors (58.6%) were more common than low grade (41.4%). The detrusor muscle was present inthe biopsy specimen of 48 patients (64%). Re-TURBT within 2–6 weeks was considered based on histopathology reports for about half of the patients (45.3%). Upstaging and upgrading of the tumor was present in 5.8 and 5.8% of the patients, respectively. Residual tumor without upstaging and upgrading was present in 23.5%. One patient (1.3%) had Clavien–Dindo grade 1, three (4%) patients had grade 2 and two patients (2.7%) had grade 3b.

Conclusion

In the present study, patients with bladder cancer are younger than reported in other studies. Smokers are strongly predisposed. The histological pattern is similar to the Western and Asian populations. NMIBC and MIBC occur in proportion to that described as in other studies. We had a lower rate of recurrence, upstaging and upgrading. We had a lesser rate of acceptance for radical cystectomy in our patients.

     

Integrated Child Development Services scheme (ICDS) and its impact on nutritional status of children in India and recent initiatives

Integrated Child Development Services (ICDS) scheme is the largest national programme for the promotion of the mother and child health and their development in the world. The beneficiaries include children below 6 years, pregnant and lactating mothers, and other women in the age group of 15 to 44 years. The package of services provided by the ICDS scheme includes supplementary nutrition, immunization, health check-up, referral services, nutrition and health education, and pre-school education. The distribution of iron and folic acid tablets and megadose of vitamin A is also undertaken, to prevent iron deficiency anaemia and xerophthalmia respectively. The scheme services are rendered essentially through the Anganwadi worker (AWW) at a village centre called "Anganwadi". The ICDS had led to (i) reduction in prevalence of severe grades of malnutrition and (ii) better utilization of services of national nutritional anaemia prophylaxis programme and the national programme for prevention of nutritional blindness due to vitamin A deficiency by ICDS beneficiaries. The ICDS scheme is being modified continuously to strengthen the programme.     

Antemortem diagnosis of Leigh’s disease: Role of magnetic resonance studies

A two-and-a-half-year-old male child presented with recurrent attacks of intractable vomiting, psychomotor retardation since 14 months of age. He had also lower cranial nerve palsy and corticospinal involvement. Magnetic resonance imaging had shown multiple well circumscribed areas of hypointusity in T, weighted image which were brightly hyperintense in heavily T₂-weighted image. The lesions were seen in basal ganglia, thalamii and brainstenvand spared mamillary bodies. Magnetic resonance spectroscopy demonstrated lactate peak in the affected areas confirming the diagnosis of Leigh’s disease. The child responded well to large dose of vitamin ‘B’, therapy.
