A critical appraisal of complications of percutaneous nephrolithotomy in paediatric patients using adult instruments.

Abstract: Objective To evaluate the complications (using the CROES Clavien scoring system) and various factors affecting them in children undergoing percutaneous nephrolithotomy (PCNL). Patients and Methods We analysed prospectively maintained data of paediatric PCNL (patients ≤17 years) from January 2008 to December 2012. Stone complexity was defined according to validated Guy's stone score (GSS). Procedures were performed in the prone position by experienced urologists. The tract was dilated (24–30F) under fluoroscopic guidance, and an adult rigid nephroscope complemented with a cystoscope/ureteroscope were used. Complications were recorded according to the CROES-Clavien score, recently defined by the Clinical Research Office of the Endourological Society (CROES) Study Group. Results The study group comprised 158 procedures performed in 153 children (98 boys and 55 girls), with a mean (range) age 10.03 ± 4.51 (2–17) years. The mean (range) stone burden was 376.68 ± 265.23 (150–2400) mm2. The distribution of cases according to the GSS was 31% grade I, 35.4% grade II, 19% grade III, and 14.6% grade IV. The stone-free rate of PCNL monotherapy was 85.4%, which increased to 93.7% after relook PCNL/extracorporeal shock wave lithotripsy. In all, 62 children (39.2%) had operative complications; 84% were minor, i.e. Clavien grade 1/2, and managed conservatively. Stone size, GSS, tract size, number of punctures and operation duration were significantly associated with complications on univariate analysis (P < 0.05). However, on multivariate logistic regression analysis, operation duration was the only independent risk factor associated with complications (95% confidence interval: 1.013–1.065, odds ratio = 1.04; P = 0.038). Conclusions Percutaneous nephrolithotomy in children using adult instruments is an effective and safe procedure for managing simple as well as complex renal calculi. Assignment of specific Clavien scores to all possible PCNL complications by the CROES PCNL Study Group have improved precision in reporting complications in a standard objective format, including the minor ones. Such models are very useful for making inter-observer comparisons to obtain clinically relevant inferences. Mean operation duration is the only independent factor affecting complications of the procedure.

Status and Interrelationship of Zinc, Copper, Iron, Calcium and Selenium in Prostate Cancer

Abstract: Deficiency or excess of certain trace elements has been considered as risk factor for prostate cancer. This study was aimed to detect differential changes and mutual correlations of selected trace elements in prostate cancer tissue versus benign prostatic hyperplasia tissue. Zinc, copper, iron, calcium and selenium were analysed in histologically proven 15 prostate cancer tissues and 15 benign prostatic hyperplasia tissues using atomic absorption spectrophotometer. Unpaired two tailed t test/Mann–Whitney U test and Pearson correlation coefficient were used to compare the level of trace elements, elemental ratios and their interrelations. As compared to benign prostatic tissue, malignant prostatic tissue had significantly lower selenium (p = 0.038) and zinc (p = 0.043) concentrations, a lower zinc/iron ratio (p = 0.04) and positive correlation of selenium with zinc (r = 0.71, p = 0.02) and iron (r = 0.76, p = 0.009). Considerably divergent interrelationship of elements and elemental ratios in prostate cancer versus benign prostatic hyperplasia was noted. Understanding of differential elemental changes and their interdependence may be useful in defining the complex metabolic alterations in prostate carcinogenesis with potential for development of element based newer diagnostic, preventive and therapeutic strategies. Further studies may be needed to elucidate this complex relationship between trace elements and prostate carcinogenesis.

Morbidity profile and seasonal variation of diseases in a primary health center in kanpur district: a tool for the health planners.

Abstract: Objective: The objective of this study was to determine the morbidity profile of patients being treated at the Primary Health Center, their distribution according to gender, and the seasonal trend of diseases. Materials and Methods: The study was done retrospectively using secondary data, over a period of 1 year from June 2007 to July 2008, at the OPD of the Primary Health Center at Patara in Kanpur District, India. The study was aimed to study the pattern of diseases according to the classification provided by the Government of India. The data were collected from the OPD registers of the consultant medical officer, and the diagnosis was classified into communicable diseases, nutritional and metabolic disorders, infectious diseases, obstetric complications, and other diseases including injuries. Results: A total of 6838 patients had been treated at the OPD, which included 2707 males and 4131 females. It was observed that, while communicable diseases constituted about half of the total burden of the diseases with skin infections being the commonest; the non-communicable diseases constituted about one-fifth of the total disease burden. Significant gender differences were evident in the prevalence of certain diseases such as worm infestation, acute respiratory tract infection, urinary tract infection, reproductive tract infection, chronic obstructive pulmonary disease, gastritis, arthritis/gout, falls/injuries/fractures, anemia, pyrexia of unknown origin, and snake bite. Most of the diseases were observed to have a seasonal variation, with the communicable and infectious diseases peaking in the monsoon months. Surprisingly, the non-communicable diseases such as gastritis and falls and injuries also showed a seasonal variation. Conclusion: Many diseases have a seasonal variation and the burden of these diseases could be reduced if we devise measures to detect the changes in their trend through the implementation of surveillance programs in this part of the world, as has been carried out in other countries. The knowledge of the burden of the diseases would also assist the health administrators in judicious allocation of the resources.

Primary synovial sarcoma of kidney: A rare tumor with an atypical presentation

Abstract: Synovial sarcoma (SS) is a tumor of the soft tissues with a unique chromosomal translocation t(X;18)(p11.2;q11.2) that can be detected by polymerase chain reaction in tissue homogenates. Here we present a case of a 20-year-old female presenting PSS of the left kidney with caval thrombus. The diagnosis was corroborated by reverse transcription polymerase chain reaction (RT-PCR). Similar cases of PSS of kidney with tumor extension in the inferior vena cava are extremely rare and to date, approximately three cases have been reported in the literature.

The ICT filariasis test : rapid format antigen test for the diagnosis of bancroftian filariasis

Abstract: Antigen testing is now recognized as the method of choice for detection of Wuchereria bancrofti infections. Unlike tests that detect microfilariae, antigen tests can be performed with blood collected during the day or night. However, existing enzyme-linked immunosorbent assay (ELISA) tests for filarial antigenemia are difficult to perform in the field, and this has limited their use in endemic countries. In this article, Gary Weil, Patrick Lammie and Niggi Weiss review their experience with a new rapid-format filarial antigen test. They found that the ICT card test was very easy to perform and that it was comparable with ELISA for the detection of filarial antigen in sera from people with microfilaremia. The introduction now of an antigen test suitable for use in the field is especially timely, in that it may facilitate implementation of new strategies proposed by the World Health Organization for control and elimination of lymphatic filariasis.

Healthcare seeking behaviour among self-help group households in Rural Bihar and Uttar Pradesh, India

Abstract: In recent years, supported by non-governmental organizations (NGOs), a number of community-based health insurance (CBHI) schemes have been operating in rural India. Such schemes design their benefit packages according to local priorities. This paper examines healthcare seeking behaviour among self-help group households with a view to understanding the implications for the benefit packages offered by such schemes.

Using high-density DNA methylation arrays to profile copy number alterations.

Abstract: The integration of genomic and epigenomic data is an increasingly popular approach for studying the complex mechanisms driving cancer development. We have developed a method for evaluating both methylation and copy number from high-density DNA methylation arrays. Comparing copy number data from Infinium HumanMethylation450 BeadChips and SNP arrays, we demonstrate that Infinium arrays detect copy number alterations with the sensitivity of SNP platforms. These results show that high-density methylation arrays provide a robust and economic platform for detecting copy number and methylation changes in a single experiment. Our method is available in the ChAMP Bioconductor package: http://www.bioconductor.org/packages/2.13/bioc/html/ChAMP.html.
