RESUMO
PURPOSE: To compare the effectiveness and safety of shockpulse with pneumatic lithotripsy in percutaneous nephrolithotomy. METHODS: A prospective randomized comparative study was performed in Department of Urology, Bir Hospital for 1-year duration with 61 patients in shockpulse (Group 1) and 58 patients in pneumatic lithoclast (Group 2) groups, respectively. Patient's demographics, stone characteristics, hemoglobin drop, hospital stay, operative duration, stone fragmentation time and postoperative complications were compared. RESULTS: The two groups did not differ significantly in terms of patient's demographic and stone characteristics. The mean hemoglobin drop was 1.96 ± 1.48 g/dl in Group 1 and 2.32 ± 1.38 g/dl in Group 2 (p = 0.16) and hospital stay was 3.14 ± 1.42 days in Group 1 and 3.29 ± 1.82 days in Group 2 (p = 0.62). The number of cases that required multiple tracts were six (9.8%) in Group 1 and 12 (20.68%) in Group 2 (p = 0.12). The stone-free rates were 78.69% in Group 1 and 74.13% in Group 2 (p = 0.66). Mean total operation time was 43.23 ± 18.49 min in Group 1 as compared to 51.53 ± 19.48 min in Group 2 (p = 0.0188). Mean stone fragmentation time was 17.95 ± 15.25 min in Group 1 and 24.37 ± 11.12 min in Group 2 (p = 0.0096). Overall complications were not significant between the two Groups (p = 0.58). On sub-analysis of the patients with single tracts in both groups the results were comparable to patients with single and multiple tracts combined. CONCLUSIONS: Despite similar stone-free rates and complications between the two Groups, shockpulse has significantly lower stone fragmentation time and total operation time as compared to pneumatic lithotripsy.

BACKGROUND: Depression is the most common form of mental disorder among inmates, with a prevalence much higher than in the general population. This study aims to estimate the prevalence of depression among inmates and identify factors associated with it. METHODS: This cross-sectional study was conducted in Jhumka Regional Prison, the largest prison in eastern Nepal, from September 2014 to August 2015. A total of 434 randomly selected inmates were interviewed using a semi-structured questionnaire examining socio-demographic characteristics, detention status, self-reported health problems, substance use status, and suicidal ideation. Depression was screened using the Center for Epidemiologic Studies Depression scale. Chi-square tests and multiple logistic regression analysis were applied to determine the association between depression and related variables. RESULTS: The mean age of the participants was 35.7 years (SD 13.3). The prevalence of depression among the inmates was 35.3%. Approximately 2.3% reported suicidal ideation during imprisonment and 0.9% had attempted suicide inside the prison. In bivariate analysis, depression was significantly associated with previous incarceration (OR = 1.91, 95% CI = 1.05-3.47, p = 0.033), poor self-rated health (OR = 1.75, 95% CI = 1.16-2.64, p = 0.007), frequent appointments when encountering health problems (OR = 1.66, 95% CI = 1.06-2.61, p = 0.028), suicidal ideation (OR = 4.44, 95%CI = 1.13-17.44, p = 0.038) and loss of weight (OR = 1.49, 95% CI = 1.00-2.23, p = 0.049). However, only previous incarceration (AOR = 1.97, 95% CI = 1.04-3.74, p = 0.037) and frequent appointments when encountering health problems (AOR = 1.61, 95% CI = 1.01-2.57, p = 0.046) remained significant in a multivariate model. CONCLUSIONS: This study showed a high rate of depression among inmates in Nepal. The results suggest a need for psychiatric and rehabilitative care in correctional settings to improve the health status of the inmates.

The human CD99 protein is a 32-kDa type I transmembrane glycoprotein, while CD98 is a disulfide-linked 125-kDa heterodimeric type II transmembrane glycoprotein. It has been previously shown that CD99 and CD98 oppositely regulate ß1 integrin signaling, though the mechanisms by which this regulation occurs are not known. Our results revealed that antibody-mediated crosslinking of CD98 induced FAK phosphorylation at Y397 and facilitated the formation of the protein kinase Cα (PKCα)-syntenin-focal adhesion kinase (FAK), focal adhesions (FAs), and IPP-Akt1-syntenin complex, which mediates ß1 integrin signaling. In contrast, crosslinking of CD99 disrupted the formation of the PKCα-syntenin-FAK complex as well as FA via FAK dephosphorylation. The CD99-induced dephosphorylation of FAK was apparently mediated by the recruitment of Src homology region 2 domain-containing phosphatase-2 (SHP2) to the plasma membrane and subsequent activation of its phosphatase activity. Further consequences of the activation of SHP2 included the disruption of FAK-talin and talin-ß1 integrin interactions and attenuation in the formation of the IPP-Akt1-syntenin complex at the plasma membrane, which resulted in reduced cell-ECM adhesion. This report uncovers the molecular mechanisms underlying the inverse regulation of ß1 integrin signaling by CD99 and CD98 and may provide a novel therapeutic approach to treat inflammation and cancer.

Background: Stroke is the third most common cause of disability and the second most common cause of death worldwide. Prognosis assessment in acute ischemic stroke is challenging for clinicians. The development of simple and easily performed prognostic markers that correlate with the outcome of patients can be of immense benefit. The aim of this study was to find out the prognostic significance of total leukocyte count, red cell distribution width and erythrocyte sedimentation rate in patients with acute ischemic stroke. Methods: A descriptive cross-sectional study was conducted in a tertiary center after ethical approval from the Institutional Review Committee. The study period spanned from April 18, 2022 to June 17, 2023, a period of 14 months. 136 patients diagnosed with acute ischemic stroke with total leukocyte count (TLC), red cell distribution width (RDW), erythrocyte sedimentation rate (ESR), National Institutes of Health Stroke Scale (NIHSS), and modified Rankin Scale (mRS) were included in the study after fulfilling the inclusion criteria. The modified Rankin Scale (mRS) was obtained 28 days following admission. Data was collected and analyzed through Microsoft Excel 365 and SPSS version 22. Spearman Correlation and multivariate regression analysis were used to analyze the association. Results: TLC, RDW, and ESR were significantly associated with an mRS at 28 days showing a positive correlation between them. Total in-hospital mortality has been significantly associated with TLC only (p < 0.05). Conclusions: The prognostic value of TLC, RDW, and ESR in patients with acute ischemic stroke was found to be significant and similar to the studies done in similar settings.
RESUMO
Lung cancer varies between Caucasians and Asians. There have been differences recorded in the epidemiology, genomics, standard therapies and outcomes, with variations according to the geography and ethnicity which affect the decision for optimal treatment of the patients. To better understand the profile of lung cancer in Southeast Asia, with a focus on India, we have comprehensively reviewed the available data, and discuss the challenges and the way forward. A substantial proportion of patients with lung cancer in Southeast Asia are neversmokers, and adenocarcinoma is the common histopathologic subtype, found in approximately a third of the patients. EGFR mutations are noted in 23-30% of patients, and ALK rearrangements are noted in 5-7%. Therapies are similar to global standards, although access to newer modalities and molecules is a challenge. Collaborative research, political will with various policy changes and patient advocacy are urgently needed.
RESUMO
Dengue is one of the most common viral infections affecting the general population in endemic areas annually. However, it is barely reported in newborns owing to a widespread belief that they are protected from severe viral infections in the first six months of life by the presence of maternal antibodies. Here we present a case of a 23-day-old male infant born to primigravida with dengue fever with the post-natal transmission of infection. He presented with complaints of fever for three days. On general examination, red-coloured pinpoint macular rashes were observed bilaterally on lower limbs. No significant findings were present on systemic examination. On routine sepsis workup, thrombocytopenia was present. Acknowledging the endemicity and expanding dengue cases, NS1 antigen and antibody IgM and IgG of the baby were tested which came positive for antigen and IgM antibody. Even so, the mother was asymptomatic with NS1 antigen, IgG and IgM antibodies negative with a normal range of platelet count. Keywords: case report; dengue fever; neonates, Nepal.

OBJECTIVES: Tuberculosis is an infectious airborne disease caused by Mycobacterium tuberculosis. Pulmonary tuberculosis is the ninth most frequent complication of diabetes mellitus. The co-existence of TB and DM in patient causes severe TB symptoms, modify radiological findings, slower response to treatment outcomes and prognosis. IFN-γ is the key cytokine which play role in the protective immune response against mycobacterium infection. The main function of IFN-γ is macrophage activation which is able to exert its microbicidal functions. Estimation and comparison of pre and post treatment serum IFN-γ among pulmonary tuberculosis among diabetic and non-diabetic patients. METHODS: The study was conducted in the Departments of Biochemistry and Pulmonary Medicine, FMHS, SGT University, Budhera, Gurugram and District TB Centre, Gurugram, Haryana, India. In this study, 100 newly diagnosed PTB patients without diabetes mellitus and 100 newly diagnosed PTB patients with diabetes mellitus (PTB-DM) above 15 years of age were included after obtaining written consent. 5 mL venous blood was collected from patients of pre and post anti-tubercular treatment. The level of IFN-γ was measured by ELISA method. RESULTS: The circulating level of IFN-γ in PTB patients was significantly decreased in post-treatment (25.53 ± 6.12 pg/mL) compared to pre-treatment (58.76 ± 16.02 pg/mL) with t-value 32.03 and p-value <0.001. The circulating level of IFN-γ in PTB-DM patients was significantly decreased in post treatment (29.11 ± 7.41 pg/mL) compared to pre-treatment (44.14 ± 10.85 pg/mL) with t-value 31.35 and p-value <0.001. In the present study, level of IFN-γ in pre-treatment PTB patients (58.76 ± 16.02 pg/mL) was significantly raised compared to PTB-DM patients (44.14 ± 10.85 pg/mL) with t-value 7.55 and p-value <0.001. However, level of IFN-γ in post-treatment PTB patients (25.53 ± 6.12 pg/mL) was significantly low compared to PTB-DM patients (29.11 ± 7.41 pg/mL) with t-value 3.71 and p-value <0.001. CONCLUSIONS: The decreased level of IFN-γ in post-treatment compared to pre-treatment in both PTB and PTB-DM patients had shown efficacy of anti-tubercular treatment. However, the post treatment level of IFN-γ was high in PTB-DM patients compared to PTB patients which verified that effect of ATT was low in PTB-DM.

Introduction: Metastatic spread of lung cancer to supraclavicular lymph nodes is considered distant metastasis for treatment purposes. Detection of supraclavicular lymph node metastasis in patients with lung cancer serves for tissue diagnosis by itself and also helps avoid more invasive biopsy from the primary lung mass itself. Ultrasonography of the lower neck can detect supraclavicular lymph nodes before they are palpable and can also be used for safe sampling of these lymph nodes. The aim of this study was to find out the prevalence of metastatic supraclavicular lymph nodes among patients with lung carcinoma in a tertiary care centre. Methods: A descriptive cross-sectional study done in a tertiary care center, carried out from 15 September 2019 to 14 September 2020. Ethical approval was obtained from the Institutional Review Committee (Reference number: 84(611)E2/076/077). The study was done among 92 patients with biopsy-proven lung cancer (lung mass or supraclavicular lymph node biopsy) who were referred for evaluation, and/or percutaneous transthoracic biopsy. Convenience sampling method was used. Point estimate and 90% Confidence Interval were calculated. Results: Among 92 patients with proven lung cancer, metastatic supraclavicular lymph nodes were seen in 13 patients (14.10%) (8.17- 19.73, 90% Confidence Interval). Among 13 patients with metastatic lymph nodes, 9 (69.23%) had palpable supraclavicular lymph nodes. The majority 11 (84.61%) had round-shaped lymph nodes. All metastatic lymph nodes showed loss of echogenic fatty hilum. A total of 12 (92.30%) metastatic lymph nodes showed a peripheral disorganized pattern of vascularity. Conclusions: The prevalence of metastatic supraclavicular lymph nodes was lower than in similar studies done in international settings. Keywords: lung cancer; malignancy; ultrasonography.

Biobanking is a relatively newly recognized and innovative branch of science, which includes the collection of samples and associated data from hospitals, diagnostic centers, and voluntary donations for biomedical and environmental research. It involves diverse stakeholders at the junction of society, science, ethics, law, and politics. A key element in the success of a biobank is the trust and support of public donors, clinicians, and scientists. To achieve trust, it is important to implement strategies that can increase biobank awareness in common people, and different types of communities. Biobank laws and regulations and transparent governance by the biobanks are also crucial to achieving public trust.

Introduction: Acne vulgaris is a common chronic inflammatory skin disease affecting the pilosebaceous unit. The clinical manifestations of acne include the development of comedones, papules, and pustules. Although generally considered benign, acne can have psychological impacts and cause disfiguring scars. The aim of this study was to find out the prevalence of acne among patients visiting outpatient department of dermatology centres. Methods: A descriptive cross-sectional study was conducted among patients visiting tertiary care skin centres from 15 June 2023 to 15 August 2023. The ethical approval was obtained from the Institutional Review Committee. The severity of acne severity and scarring was determined. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 2036 patients, acne was found in 386 (18.96%) (17.26-20.66, 95% Confidence Interval). The majority of participants have acne scar grade 2 (65.20%). Conclusions: The prevalence of acne among patients was found to be higher than in other studies done in similar settings. Keywords: acne; scars; prevalence.

OBJECTIVES: PCOS is the most common endocrinological disorder amongst women of reproductive age. The consequences of PCOS extend beyond the reproductive axis and may lead to the development of metabolic syndrome leading to a high risk for hypertension and cardiovascular disease. Therefore, a more comprehensive evaluation of biochemical markers that reflect the cardiovascular risk is required for further understanding of pathophysiologic mechanisms, diagnosis and management. METHODS: In this case-control study, women diagnosed with PCOS (n=100) in the age group (18-35 years) years were taken as cases and age matched healthy controls (n=100) were enrolled. Estimations of fasting plasma Glucose, serum total cholesterol (TC), triglycerides (TG) and High-density lipoprotein (HDL) concentrations were assayed while Low-density lipoprotein (LDL) was calculated by using Fredrickson Friedwald's formula. Serum Lipoprotein-a (Lp-a) was estimated using ELISA (Enzyme Linked Immunosorbent Assay). The quantitative data were expressed as Mean ± Standard Deviation (SD). Unpaired Student's t-test was used to compare the values (PCOS vs Controls) and Pearson's correlation coefficient was used to elucidate the relationship between the variables. RESULTS: FBS and all lipid parameters were significantly increased in PCOS patients compared to control subjects. On the other hand, HDL-C was significantly decreased as compared to the control subjects. The hormones TSH, LH, FSH, PRL and LH/FSH ratio were significantly increased in PCOS patients compared to control subjects. Lipoprotein-a and PAI-1 was significantly increased in PCOS patients compared to the control subjects. Upon bivariate correlation analysis, Lp(a) had significant correlations with PAI-1 (r=0.35, p=0.000), WHR (r=0.25, p=0.000), LDL (r=0.52, p=0.000) and TSH (r=0.24, p=0.000). While the correlations with FBS (r=-0.008, p=0.91) and LH/FSH ratio (r=-0.004, p=0.95) were statistically insignificant. CONCLUSIONS: The evaluation of serum biomarkers such as Lp-a, PAI-1 and lipid profile routinely in PCOS patients may have diagnostic role in the early detection of metabolic abnormalities and endocrine derangements and timely management of comorbid Diabetes and Cardiovascular disease in PCOS females.

Statement of the Problem: Several standards and guidelines for biobanks or biorepositories have been published by various parties (e.g., the International Society for Biological and Environmental Repositore [ISBER] and the International Organization for Standardization [ISO]). These documents are invaluable for improving the routine practices of the biobanks but the implementation has proven to be challenging for those biobanks from the non-English regions because these resources are mostly written in English. Proposed Solution: The World Health Organization (WHO) has recently published the International Classification of Diseases 11th Revision (ICD-11) along with a translation tool (lexique) for potential users. This has inspired us to make a similar contribution in the biobanking field. All the regional ambassadors (RAs) and director-at-large (DAL) in the Indo-Pacific Rim (IPR) region worked together to produce a similar lexique for potential users of ISBER's Best Practices (BPs) 4th edition. A lexique with languages of Hindi, Indonesian, Vietnamese, and Japanese has been prepared. Conclusions: This lexique is a comparison table between various languages and is expandable to other languages. In addition, this lexique will be a good tool for understanding the ISBER BPs 4th edition.

Calls to reduce or entirely remove the carbon footprint of ongoing activities, collectively termed as decarbonization, have become increasingly more vocal in health care with a number of recent, high profile consensus statements. These calls encourage the biobanking field, as one of the foundational health care research infrastructures, to consider decarbonization as a potential novel research area both in terms of the molecules and the equipment used in research. The current article provides a summary of the roundtable discussion during the 2022 ISBER Annual Meeting and Exhibits, highlighting the current knowledge gaps, challenges, and opportunities in this field. In particular, technological innovation, a greater awareness of the current situation, and behavioral change are important pieces of the puzzle to improving the future of decarbonization in biobanking, even if the eventually implemented routes between resource-abundant and resource-restricted settings might be distinctly different. This article sets the foundation for raising awareness of the subject and of subsequent steps that need to be undertaken.

IMPORTANCE: No proven treatment is available for severely ill COVID-19. Therapeutic use of COVID-19 convalescent plasma (COPLA) is under investigation. OBJECTIVE: To compare the efficacy of COPLA with standard medical therapy (SMT) alone in severe COVID-19 patients. DESIGN, SETTING AND PARTICIPANTS: A multicentric, open-labelled, phase-III randomised controlled trial conducted at two treatment centres with COPLA collected at the third dedicated centre in North-India, the coordinating centre during trial from June 2020 to December 2020. The study population comprised 400 participants in the ratio of 1:1 in each treatment group. INTERVENTION: One group received COPLA with SMT (n=200), and another group received SMT only (n=200). MAIN OUTCOME MEASURES: Primary outcome was time to clinical improvement measured by a two-point reduction in the ordinal scale. Secondary outcomes included duration of O2 therapy, the proportion of patients on mechanical ventilation at day-7, mortality, SARS-CoV-2 antibody levels, cytokine levels and incidence of adverse events. RESULTS: The median time to a two-point reduction in the ordinal scale in both groups was 9 days (IQR=7-13) (p=0.328). The median duration of O2 therapy was 8 days (IQR=6-12) in COPLA and 10 days (IQR=6-12) in SMT group (p=0.64). The PaO2/FiO2 ratio showed significant improvement at 7 days in COPLA group(p=0.036). There was no difference in mortality till 28 days in both groups (p=0.62). However, if COPLA was given within 3 days of hospital admission, a significant reduction in ordinal scale was observed (p=0.04). Neutralising antibody titres in COPLA group (80 (IQR 80-80)) were higher than SMT group (0 (IQR 0-80)) at 48 hours (p=0.001). COPLA therapy led to a significant reduction in TNF-α levels at 48 hours (p=0.048) and D-dimer at 7 days (p=0.02). Mild allergic reactions were observed in 3 (1.5%) patients in COPLA group. CONCLUSION AND RELEVANCE: Convalescent plasma with adequate antibody titres should be transfused in COVID-19 patients along with SMT in the initial 3 days of hospitalisation for better clinical outcomes. TRIAL REGISTRATION NUMBER: NCT04425915.

BACKGROUND: Severe acute malnutrition (SAM) is the most extreme and visible form of undernutrition plagued by chronic poverty, household food insecurity, lack of education. One of the indigenous and marginalized community of Nepal, Satar/Santhal has often been neglected and is devoid of good education and are economically deprived. This predisposes under 5 children of Satar into malnutrition. The study aims to assess determinants of SAM among children under 5 years of age in Satar community of Jhapa district, Nepal. MATERIAL & METHODS: A community based matched case control study was carried from September 2019 to February 2020 among under five children of Satar community residing in Jhapa district. Multistage random sampling technique was used to select 50 cases and 100 controls in the ratio of 1:2. Information was collected through personal interview with the parents and anthropometric measurement of the children was measured. Bivariate and multivariate conditional logistic regression analysis was used to explore the determinants of severe acute malnutrition. RESULTS: A total of 664 children between the age group of 6-59 months were screened for SAM. The prevalence of SAM was found 7.53%. Factors like, low economic status, birth interval less than 2 years, frequency of breast feeding <8 times/day and household food insecurity were found to be significant determinants of SAM. Multivariate logistic regression documented low economic status (AOR: 11.14, 95% CI 1.42 to 87.46); and frequency of breast feeding <8 times/day (AOR: 2.09, 95% CI 1.00 to 4.37) as determinants of SAM. CONCLUSION: Low economic status and frequency of breast feeding less than 8times/day were major determinants of SAM among children under 5yrs of age. Ending malnutrition will require greater efforts and integrated approaches to eradicate extreme poverty. Multi-sector approaches have been conducting for SAM in Nepal but there are no specific approaches for marginalized community.

Background: Biobankers have been unexpectedly involved in the pandemic of COVID-19 since early 2020. Although specific guidance was not available, the International Society for Biological and Environmental Repositories (ISBER) Best Practices and the ISO 20387 document have been utilized to deal with the pandemic disaster. The ISO experts and best practice experts in ISBER teamed up to share the available information and learn the experiences of biobanks concerning COVID-19 through organizing webinars, surveys, and town hall meetings. Four ISBER regional ambassadors (RAs) from the Indo-Pacific Rim (IPR) region were also actively involved at one of the town hall meetings. These RAs, who are from Australia, India, Indonesia, and Japan, and the Director-at-Large of the region, have summarized their experiences in this article. Materials and Methods: The ISBER Standards Committee COVID-19 Task Force has kindly provided the survey results. The extracted glossary from the results was categorized into 10 factors: (1) crisis management; (2) sample-related issues; (3) logistics-related issues; (4) equipment-related issues; (5) ethical, legal, and social implication-related issues; (6) operation-related issues; (7) personnel-related issues; (8) management-related issues; (9) infection-related issues; and (10) research-related issues. Each IPR RA has provided a case considering these 10 factors. Results and Discussion: Two key points have emerged from the scenarios, which are as follows: (1) impacts of the biobanks in low- and middle-income countries (LMICs) are similar to those in high-income countries (HICs) and (2) tolerance of the biobanks in LMICs is not so robust as those in HICs. Furthermore, communication strategies with internal and external stakeholders are critical for a biobank to manage this crisis. This article summarizes the impacts, indicates the opportunities that COVID-19 has brought to the biobank community, and highlights the usefulness of the network beyond biobank services. Lastly, the biobanks need to turn the challenges into opportunities to overcome the crisis.

Genes involved in the hemostatic mechanism are logical candidate genes for association studies in prothrombotic conditions such as stroke. Since the underlying etiology in pediatric strokes is different than adults, looking for genetic causes would be the logical thing to do in the pediatric stroke population. Fifty-eight Asian-Indian stroke patients below 15 years of age and equal number of age- and sex-matched healthy controls were the subjects for the study. The subjects were screened for 13 polymorphisms and three mutations spread across seven different candidate genes involved in the hemostatic system. Of the 13 polymorphisms and three mutations studied, four polymorphisms, HPA-I, TAFI 147Ala>Thr, methylene tetrahydrofolate reductase (MTHFR) 677 C>T, and MTHFR 1298 A>C, showed significant association with the disease phenotype. MTHFR 677 C>T showed the strongest association and therefore may have a strong predisposing role for pediatric strokes. Gene-gene interaction studies showed a strong interaction between HPA-I and MTHFR 677 C>T polymorphism. The wild type of both these polymorphisms synergistically showed a strong protective effect [p < 0.0001, O.R: 10.06(4.26-23.71)]. Polymorphisms in HPA-I and MTHFR may have important predisposing roles in the development of pediatric stroke.

Thirty-three patients of Glanzmann's thrombasthenia (GT) and their families were assessed for the expression of alphaIIbbeta3 on platelet surface, by flow cytometry, to determine the common subtypes in North Indians as well as to assess the carrier status in family members of GT patients. GT was diagnosed in patients with bleeding manifestations accompanied by absent/reduced platelet aggregation, secondary to adenosine-di-phosphate, adrenaline, arachidonic acid and collagen. Based on alphaIIbbeta3 levels, 21 patients (64%) were classified as type I (as alphaIIbbeta3 was absent), 4 patients (12%) as type II and 8 patients (24%) as type III. Eight out of 20 fathers, 10 out of 20 mothers and 20 out of 31 siblings were found to have reduced alphaIIbbeta3 levels. Reduced alphaIIbbeta3 expression was seen in 63% of parents and 65% of siblings. It is possible that low alphaIIbbeta3 levels in family members may reflect their carrier status. It is postulated that flow cytometry estimation of alphaIIbbeta3 in parents/siblings may detect carrier status in GT. It is also revealed that type I GT is the commonest subtype in North Indians.

BACKGROUND: Homocysteine has been for a fairly long time been debated to be a risk factor for stroke. Opinions are divided as to whether raised levels of homocysteine seen in stroke patients are the cause or consequence of stroke. A large number of studies have been conducted in the Caucasian as well as on the Oriental population, which tend to suggest contradictory findings at many times. However, there have been no reports forthcoming from the Asian Indian population, which is a genetically different population than the previously studied populations. SUBJECTS AND METHODS: In our present study, we looked at homocysteine levels and four commonly seen polymorphisms of homocysteine metabolizing enzymes and their respective prevalence in 120 acute onset ischemic stroke patients compared with an equal number of age and gender matched healthy population. We also tested the influence of folic acid dosage (5 mg OD) on the levels of homocysteine and the allied vitamin supplements, vitamin B12 and folate in smaller groups selected from the larger group. RESULTS AND CONCLUSIONS: We found homocysteine levels to be significantly raised in the stroke population compared with healthy controls [patients: 12 micromol/L (range: 5.3-39.1 micromol/L), controls: 11.2 micromol/L (range: 6.2-14.2 micromol/L); P =0.001]. There was an almost total response to folic acid dosage as all hyperhomocysteinemic patients showed lowering of homocysteine levels in response to the dosage. The MTHFR 677 C > T polymorphisms showed association with both homocysteine levels as well as stroke (P < 0.001). Nutritional deficiency plays a dominant role in hyperhomocysteinemic conditions in our stroke population, however. Genetic determinants of homocysteine level may also have some part in determining hyperhomocysteinemic conditions in the Asian Indian populations.

BACKGROUND: Urinary stone disease has high prevalence in our belt. The end stage complication of this disease turns out to be a non-functioning kidney, which in fact could be prevented by means of appropriate treatment and follow up. METHODS: This is retrospective study of the nephrectomy cases of last 8 years retrieved from the hospital database. Variables like age, sex, indications for nephrectomy, modalities of nephrectomy and morbidities among the primary and recurrent disease were taken into consideration. Analysis were done using Microsoft Excel 2016. RESULTS: Five hundred and twenty-nine nephrectomies were performed in last 8 years at our hospital. Female were more prone for nephrectomies. Age at third and fourth decade were most to be affected. Ninety percentage of nephrectomies were done for benign causes, 65% for the stone disease. The recurrent renal stone disease without any past surgical interventions were more prone to undergo nephrectomies. The conventional open technique of nephrectomy has largely been replaced by laparoscopic means in recent years. CONCLUSIONS: The main contributor for nephrectomy in our context is urinary stone disease, which is considered to be the preventable factor Keywords: Nephrectomy; renal stone; urinary stone disease.
