Dermoscopy as an Auxiliary Tool in the Assessment of Malassezia Folliculitis: An Observational Study.

Malassezia folliculitis is an under-recognizedentity commonly affecting the face and upper trunk. Clinical picture mimics acne vulgaris and diagnosis is challenging at times. 10% potassium hydroxide examination is usually performed to confirm the diagnosis. This study sought to describe the dermoscopic features in Malassezia folliculitis. Patients diagnosed clinically with Malassezia folliculitis and confirmed by 10% potassium hydroxide preparation were included in the study. Dermoscopy was performed with a videodermatoscope [Dinolite AM413ZT; Polarising] from the most representative lesion. A total of 45 patients (M:F = 1:0.8 ) were recruited. All patients had monomorphic papulo-pustular lesions. Itching was present in 64.4% patients. Dermoscopy reveled folliculocentricity (100%), perilesional background erythema (100%), dotted/linear/tortous vessels (88.9%), dirty white scaling (77.8%), hypo pigmentation of hair follicle (64.4%), coiled/looped hairs (57.8%) and broken hairs (13.3%). In conclusion, dermoscopy shows typical features in Malassezia folliculitis and can serve as a office based tool for identification of this entity.

Malassezia folliculitis is an under-recognized entity commonly affecting the face and upper trunk. Clinical picture mimics acne vulgaris and diagnosis is challenging at times. Ten percent potassium hydroxide examination is usually performed to confirm the diagnosis. This study sought to describe the dermoscopic features in Malassezia folliculitis. Patients diagnosed clinically with Malassezia folliculitis and confirmed by 10% potassium hydroxide preparation were included in the study. Dermoscopy was performed with a videodermatoscope (Dino-Lite AM413ZT; Polarizer) from the most representative lesion. A total of 45 patients (M:F=1:0.8) were recruited. All patients had monomorphic papulo-pustular lesions. Itching was present in 64.4% patients. Dermoscopy reveled folliculocentricity (100%), perilesional background erythema (100%), dotted/linear/tortous vessels (88.9%), dirty white scaling (77.8%), hypopigmentation of hair follicle (64.4%), coiled/looped hairs (57.8%) and broken hairs (13.3%). In conclusion, dermoscopy shows typical features in Malassezia folliculitis and can serve as a office-based tool for identification of this entity.

The hypospadias-specific health-related quality of life conceptual framework: a scoping review of the literature.

PURPOSE: Health-related quality of life (HRQoL) is an important yet understudied construct for individuals with hypospadias (HS). An important barrier towards understanding HRQoL and integrating it into research and clinical care for people with HS is the absence of an underlying conceptual framework to illustrate this construct. We propose a conceptual framework for HS-specific HRQoL based upon a scoping review of the HS literature. METHODS/MATERIALS: We conducted a literature review of articles published between 1989 and 2019. Our search in Embase and Pubmed used the keyword "hypospadias" in combination with "quality of life" and "patient-reported outcomes." We used thematic analysis of the resulting publications to identify core HRQOL domains. From these results and review of HRQoL literature in other pediatric populations, we developed a conceptual framework representing HS-specific HRQoL. RESULTS: We identified five domains of HRQOL previously studied in research with youth and adults with HS: penile appearance, voiding, social interaction, sexual health, and psychological or behavioral function. We propose a model of HS-specific HRQoL comprised of these domains and their areas of overlap, based upon the findings and conceptual mapping of our literature review. CONCLUSION: This novel conceptual framework provides a foundation for understanding disease-specific HRQoL in individuals with HS and may serve as a guide for the conduct of future qualitative studies of the HS population. The overlapping biopsychosocial domains illustrate the possible effects of HS on day-to-day life. This framework may guide future surgical, clinical, and behavioral interventions that aim to improve medical care and quality of life outcomes for HS patients.

How common are vascular injuries in open tibial fractures? A prospective longitudinal cohort study.

BACKGROUND: Tibial fractures have an incidence of 15% of all adult fractures. They have been shown to have the highest incidence of non-union in long bone fractures and the highest incidence of vascular injury. Evidence from the literature suggests that a good vascular supply is important to ensure bone union. The aim of our study was to prospectively assess the incidence of vascular injuries in open tibial fractures and determine whether they were associated with an increased risk of non-union. METHODS: We performed a prospective study to investigate the incidence of arterial injuries with computed tomography angiography (CTA) in patients with Gustilo-Anderson grade I-III open tibial fractures between 2013 and 2015. CTA was performed with the trauma series at acute admission and reported by two independent musculoskeletal radiologists. Patients were followed up with clinical and radiographic assessment for 1 year. RESULTS: We recruited 77 patients into the study, and 56 patients (47 males, 9 females) were available for the final analysis, between 16 and 90 years of age. At the initial assessment, 29% had signs of arterial injury with active extravasation in 5%. The most common site of injury was in the diaphysis (87.5%), and the commonest mechanism was a road traffic accident. We found no significant relation between occult vascular injury and non-union (p > 0.05). CONCLUSION: The incidence of vascular injury in open tibial fractures is 29%, and CTA is therefore a useful test in identifying vascular injuries that may require vascular intervention.

Paraduodenal pancreatitis.

Paraduodenal pancreatitis is a distinct clinicopathological entity involving the duodenum and the pancreatic tissue in the vicinity of the minor papilla. Most afflicted patients are young alcoholic males who present clinically with upper abdominal pain, weight loss, nausea, and vomiting. Pancreatic tissue elements in the duodenal wall and impedance to exocrine pancreatic secretions at the minor papilla are key factors in the pathogenesis of this condition. On imaging, the condition may manifest as a solid fibrotic mass around the minor papilla or as cysts in the duodenum and the pancreaticoduodenal groove. Duodenal stenosis, biliary strictures, chronic calcifying pancreatitis, and pancreatic ductal dilatation are also often observed.

Serum 25 hydroxyvitamin D profile after single large oral doses of cholecalciferol (vitamin D3) in medical staff in North India: a pilot study.

BACKGROUND: Vitamin D deficiency is widely prevalent in India and subjects who have almost no exposure to sunlight are severely deficient. Daily oral doses of cholecalciferol (vitamin D3) are costly as compared to stoss doses and further, take a long time for the serum levels to reach a plateau. Compliance to supplementation may also be better if a regimen involves single oral doses of vitamin D at specified intervals rather than daily doses. Evidence-based guidelines regarding the dosing and the frequency of dosing for prophylactic intermittent supplementation (stoss doses) in severely-deficient subjects are few. MATERIALS AND METHODS: In a prospective intervention study, we serially assessed 30 asymptomatic healthy medical staff for serum 25-hydroxyvitamin D [25(OH)D] and parathyroid hormone (PTH); (a) at baseline; (b) monthly for 3 months after single oral 60,000 units (U) cholecalciferol; (c) monthly for 3 months after 120,000 (or 180,000 for those with elevated alkaline phosphatase) U cholecalciferol; and, (d) subsequently, at 3 months after a repeat dose of 60,000 U cholecalciferol by repeated measures analysis of variance. RESULTS: The baseline serum 25(OH)D was 7.1 ± 5.4 ng/mL (< 10 ng/mL in 85% subjects) which increased to 18.7 ± 8.9 ng/mL at 1 month after 60,000 U of cholecalciferol (P < 0.001) and decreased to 11.1 ± 5.3 ng/mL by the 3 rd month. The higher dose of 120,000 (or 180,000) U increased mean 25(OH)D to 28.9 ± 9.9 ng/mL at the end of 1 st month, declining to 17.9 ± 4.9 ng/mL (P < 0.001) at 3 months. With the subsequent 60,000 U the serum 25(OH)D was 18.4 ± 3.9 ng/mL at 3 months. PTH showed a corresponding negative trend. No hypercalcemia was observed. CONCLUSIONS: Vitamin D deficiency is highly prevalent amongst medical staff in Northern India. An initial dose of 120,000-180,000 U of cholecalciferol is required to elevate 25(OH)D out of the deficiency range. Maintenance dose is needed at 2 months.

Comparative Analysis of Stereotactic Radiation Therapy and Conventional Radiation Therapy in Cancer Pain Control: A Systematic Review and Meta-Analysis.

AIMS: Approximately 55% of patients diagnosed with primary or metastatic cancer endure pain directly attributable to the disease. Consequently, it becomes imperative to address pain management through a comparative analysis of stereotactic radiotherapy (SRT) and conventional radiation therapy (CRT), especially in light of the less efficacious improvement achieved solely through pharmacological interventions. MATERIALS AND METHODS: A systematic exploration was undertaken on PubMed, the Cochrane Library, and Elsevier's ScienceDirect databases to identify studies that compare Stereotactic Radiotherapy to Conventional radiation therapy for pain management in individuals with metastatic bone cancer. The analyses were executed utilizing the random-effects model. RESULTS: A cohort of 1152 participants with metastatic bone cancer was analyzed, demonstrating significantly higher complete pain relief in the Stereotactic Radiotherapy group during both early and late follow-up (RR: 1.61; 95% CI: 1.17, 2.23, p-value: 0.004; I2: 0%). Stereotactic Radiotherapy also showed a non-significant increase in the incidence of partial pain relief (RR: 1.07; 95% CI: 0.85, 1.34, p-value: 0.56; I2: 18%). Furthermore, Stereotactic Radiotherapy was associated with a significantly reduced risk of stationary pain throughout follow-up (RR: 0.61; 95%CI: 0.48, 0.76, p-value: <0.0001; I2: 0. The incidence of progressive pain was non-significantly reduced with Stereotactic Radiotherapy during both early and late follow-up (RR: 0.77; 95% CI: 0.50, 1.17, p-value: 0.22; I2: 0%). Secondary outcomes exhibited a non-significant trend favoring Stereotactic Radiotherapy for dysphagia, esophagitis, pain, and radiodermatitis, while a non-significant increase was observed for nausea, fatigue, and vertebral compression fracture. CONCLUSION: In summary, stereotactic radiation therapy (SRT) has improved in achieving complete pain relief while exhibiting a decreased probability of delivering stationary pain compared to conventional radiation therapy (CRT). Nevertheless, it is crucial in future research to address a noteworthy limitation, specifically, the risk of vertebral compression fracture.

Prospective clinical study of endoscopic ultrasound-guided choledochoduodenostomy with direct metallic stent placement using a forward-viewing echoendoscope.

A prospective clinical study was conducted to evaluate the safety, feasibility, and efficacy of endoscopic ultrasound (EUS)-guided choledochoduodenostomy (CDS) with direct metallic stent placement using a prototype forward-viewing echoendoscope. The indication for EUS - CDS in this study was lower biliary obstruction only, and not failed endoscopic biliary drainage, because the aim was to evaluate EUS - CDS for first-line biliary drainage therapy. The technical and functional success rates were 94 % (17 /18) and 94 % (16 /17), respectively. Early complications (focal peritonitis) were encountered in two patients (11 %). No patients developed late complications. EUS - CDS with direct metallic stent placement using a forward-viewing echoendoscope was generally feasible and effective for malignant distal biliary tract obstruction. The forward-viewing echoendoscope was useful, especially for deploying the metallic stent.

Opportunities to prevent and manage undernutrition to amplify efforts to end TB.

The bidirectional relationship between TB and nutrition is well recognized - primary undernutrition is a risk factor for developing TB disease, while TB results in wasting. Although nutrition support is acknowledged as an important intervention in TB programmes, it is seldom afforded commensurate priority for action. TB incidence and deaths worldwide are falling too slowly to meet WHO End TB Strategy milestones, and the number of undernourished people is increasing, likely to be further exacerbated by the ongoing COVID-19 pandemic. Undernutrition needs to be more urgently and intensively addressed. This is especially true for the WHO South-East Asia Region, where the high rates of undernutrition are a key driver of the TB epidemic. The evidence base has been sufficiently robust for clear and workable programmatic guidance to be formulated on assessment, counselling and interventions for TB patients. Many high-burden countries have developed policies addressing TB and nutrition. Gaps in research to date have frustrated the development of more refined programmatic approaches related to addressing TB and malnutrition. Future research can be shaped to inform targeted, actionable policies and programmes delivering dual benefits in terms of undernutrition and TB. There are clear opportunities for policy-makers to amplify efforts to end TB by addressing undernutrition.

External validation of a low fidelity dry-lab platform to enhance loupes surgical skills techniques for hypospadias repair.

INTRODUCTION: Hypospadias repair is an index pediatric urology procedure that requires trainee familiarity with surgical loupes. A previous low-fidelity, 6-step curriculum was proposed that deconstructed the most important steps of loupe surgery. We expanded on this curriculum with an intermediate-fidelity silicone hypospadias model and designed an abbreviated version of the 6-step curriculum to precede the hypospadias repair simulation. OBJECTIVE: To assess the validity of our prior, low-fidelity conceptual model using the metric of improved performance on the intermediate-fidelity silicone hypospadias model. STUDY DESIGN: A silicone model was first prototyped with the design software Solidworks™, and then fabricated using a cast made of a mixture of silicone rubbers designed to function like skin and soft tissue (Mold Star 20T, Dragon skin FX-pro and Slacker). Casts were used to create the penile shaft model and the dorsal hooded foreskin model. The urethral plate was cast separately on a flat surface. The model was then assembled by hand. The model used for simulation included the penile shaft and urethral plate, while the dorsal-hooded foreskin was prepared to simulate the penile anatomy separately. Trainees were then divided into two groups. Group 1 practiced the low-fidelity curriculum (3 tasks) and then performed dissection of the urethral plate and suturing using the intermediate-fidelity hypospadias model. Group 2 practiced hypospadias repair prior to the low-fidelity curriculum. Both groups' models were scored by 3 blinded urologists. Trainees were then asked to complete a post simulation satisfaction survey. Data analysis was performed in IBM SPSS Statistics for Macintosh (Version 28.0 Armonk, NY: IBM Corp). RESULTS: Twenty-two candidates across Wisconsin, USA, and Dublin, Ireland participated in the study. This included 7 s-year residents, 9 third-year residents, 2 fourth-year residents, and 3 fifth-year residents. Both Groups 1 and 2 had a similar distribution of trainees (p = 0.60). Group 1 outperformed group 2 in all tasks (p < 0.05, Table 1). Trainees reported that the platform was very useful (91%). DISCUSSION: Our curriculum showed improvement in trainee ability and comfort to perform hypospadias repair. Advantages of such a simulated curriculum include improving current resident training in microsurgery, improving surgical ergonomics for trainees prior to real-time experience, and decreasing the learning curve for trainees pursuing pediatric urology. CONCLUSION: An intermediate-fidelity hypospadias platform externally validates the conceptual model implemented in the low-fidelity loupes curriculum. This appears to lead to improvement in loupe surgical skills regardless of trainee level.

Urgent need to address the slow scale-up of TB preventive treatment in the WHO South-East Asia Region.

In September 2018, all countries made a commitment at the first ever United Nations High-Level Meeting (UNHLM) on TB, to provide TB preventive treatment (TPT) to at least 30 million people at high-risk of TB disease between 2018 and 2022. In the WHO South-East Asia Region (SEA Region), which accounts for 44% of the global TB burden, only 1.2 million high-risk individuals (household contacts and people living with HIV) were provided TPT (11% of the 10.8 million regional UNHLM TPT target) in 2018 and 2019. By 2020, almost all 11 countries of the SEA Region had revised their policies on TPT target groups and criteria to assess TPT eligibility, and had adopted at least one shorter TPT regimen recommended in the latest WHO TPT guidelines. The major challenges for TPT scale-up in the SEA Region are resource shortages, knowledge and service delivery/uptake gaps among providers and service recipients, and the lack of adequate quantities of rifapentine for use in shorter TPT regimens. There are several regional opportunities to address these gaps and countries of the SEA Region must make use of these opportunities to scale up TPT services rapidly to reduce the TB burden in the SEA Region.

Evaluating quality of patient-reported outcome measures in patients with hypospadias.

INTRODUCTION: There is growing recognition of the importance of patient-reported outcomes (PROs) in pediatric hypospadias. We have previously presented a conceptual framework for Hypospadias-Specific Health-Related Quality of Life (HRQoL), which posited 5 domains of HRQoL in this population. The framework components (domains) included penile appearance, voiding function, social function, psychological/behavioral function, and pubertal/sexual health. In this work, we investigated the established validity and relevance of PROs within each of these domains for patients with hypospadias. MATERIALS AND METHODS: We evaluated existing measures with published psychometric data, including validation data, in the hypospadias population. We also assessed the available data on each measure according to the guidelines of the Scientific Advisory Committee of the Medical Outcomes Trust (Table) in order to establish measure quality. We also examined the power of existing validation studies according to suggested guidelines for psychometric validation and factor analysis. DISCUSSION: Available validated measures in the hypospadias population have focused primarily on penile appearance and to a lesser degree on pubertal development/sexual health. There were no validated disease-specific measures with dedicated evaluations of other key HRQoL domains including voiding-related sequelae, social function, or psychological function. In addition, no single measure addressed all of the quality guidelines posed by the Scientific Advisory Committee. CONCLUSIONS: Current generalized measures for PROs lack relevance to the experience of hypospadias patients, and disease-specific assessments are often focused on penile appearance. Improving measure quality is necessary to optimize the value of our assessments and better help our patients with hypospadias.

Development of pancreatic cancers during long-term follow-up of side-branch intraductal papillary mucinous neoplasms.

BACKGROUND AND STUDY AIMS: Side-branch intraductal papillary mucinous neoplasms (SB-IPMNs), and associated synchronous and metachronous pancreatic cancers are increasingly detected as imaging modalities become more sensitive. We investigated the natural history of SB-IPMN, and the incidence and characteristics of pancreatic cancers among patients undergoing long-term follow-up. PATIENTS AND METHODS: We reviewed the clinical, imaging, and pathological features in 103 patients, diagnosed at the Aichi Cancer Center between September 1988 and September 2006 as having SB-IPMN, and conservatively followed up for ≥ 2 years (median 59 months) based on an endoscopic ultrasonography (EUS) database. RESULTS: 74 (71.8 %) patients had nonprogressive lesions. Overall, six patients (5.8 %) developed pancreatic cancers during follow-up, with intraductal papillary mucinous (IPM) carcinoma in four, and ductal carcinoma of pancreas that was not IPMN in two patients. Of the six pancreatic cancers, five were diagnosed at a resectable stage. The 5-year and 10-year actuarial rates of development of pancreatic cancer were 2.4 % and 20.0 %, respectively. Although, at the last follow-up, cyst size, main pancreatic duct (MPD) diameter, mural nodule size, and frequency of metachronous and/or synchronous cancers of other organs were significantly higher in patients who developed IPM carcinoma, resected SB-IPMNs without mural nodules and dilated MPDs had no IPM carcinomas. CONCLUSIONS: The frequency of pancreatic cancers is high on long-term follow-up of SB-IPMN. Although conservative management is appropriate for selected patients, regular and long-term imaging, especially by EUS is essential, even if SB-IPMN remains unchanged for 2 years. Presence of mural nodule and dilated MPD seem to be more appropriate indicators for resection than cyst size alone for SB-IPMNs.

Two novel AIRE mutations in autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) among Indians.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare recessive disorder resulting from mutations in the autoimmune regulator (AIRE) gene. There is no information on AIRE mutations in Indians. In a cross-sectional study, nine patients (eight families), from four referral hospitals in India, were studied for AIRE mutations by direct sequencing. We screened for new mutations in 150 controls by allele-specific PCR. The patients had 1-7 known components of APECED. Three patients had unusual manifestations: presentation with type 1 diabetes; chronic sinusitis and otitis media; and facial dysmorphism. All patients carried homozygous, probably recessive, AIRE mutations. Two unrelated patients from a small in-bred community (Vanika Vaisya) in south India carried an unreported missense mutation, p.V80G, in the N-terminal caspase recruitment domain. Another unique mutation, p.C302X, resulting in a truncated protein with deletion of both zinc-finger domains, was detected in a patient from Gujarat. Neither mutation was detected in controls. Other mutations, previously described in Caucasians, were: 13 base pair deletion (p.C322fsX372) in 4 (38%), and Finn-major (p.R257X) and p.R139X (Sardinian) mutation in one subject each. In conclusion, in this first series of APECED in Indians, we detected AIRE mutations previously reported in Caucasians, as well as unique mutations. Of these, p.V80G is possibly an ancestral mutation in an in-bred community.

Adults with Tourette's syndrome with and without attention deficit hyperactivity disorder.

OBJECTIVE: Comorbidity between Tourette's syndrome (TS) and attention deficit hyperactivity disorder (ADHD) is high. In children, those with both TS+ADHD fare less well than those with TS-only on measures of both psychopathology and behaviour. The objective of this study was to document such measures in adult patients. METHOD: Eighty adults with TS-only were compared to 64 with TS+ADHD using a clinical interview and standardised measures of depression, anxiety and obsessionality. RESULTS: The two groups were no different on measures of TS severity. TS+ADHD patients had significantly more depression, anxiety, obsessive-compulsive behaviour and maladaptive behaviours than patients with TS-only. There were also significant differences in the incidence of copro- and echo-phenomena and family history of ADHD. CONCLUSION: The finding of increased overall behavioural difficulties and psychopathology in adult patients with TS+ADHD when compared with TS-only is in agreement with previous findings in children with TS. Appropriate treatment of ADHD in TS patients during childhood may prevent many behavioural problems in adulthood.

EUS-guided choledochoduodenostomy for palliative biliary drainage in patients with malignant biliary obstruction: results of long-term follow-up.

Five patients with obstructive jaundice caused by malignant periampullary biliary stenosis underwent EUS-guided choledochoduodenostomy (EUS-CDS) from the first portion of the duodenum using a convex echoendoscope and a needle knife. All the steps of the procedure including passage dilatation and the plastic stent placement were performed through the accessory channel of the echoendoscope over the guide wire. Stent insertion was technically successful in all five patients. The procedure was also clinically effective in relieving jaundice in all cases. One patient developed pneumoperitoneum, which resolved with conservative management. Stent exchange was successful in seven of eight attempts in patients with stent occlusion. One failure was due to tumor invasion to the choledochoduodenal fistula. Stent patency was maintained in the remaining patients throughout their survival period. The average stent patency was 211.8 days. EUS-CDS from the first portion of the duodenum appears to be feasible and safe in cases of obstructive jaundice caused by distal bile duct obstruction.

Hypogonadotrophic hypogonadism in type 2 diabetes.

Recent work shows a high prevalence of low testosterone and inappropriately low luteinizing hormone (LH) and follicle stimulating hormone (FSH) concentrations in type 2 diabetes. This syndrome of hypogonadotrophic hypogonadism (HH) is associated with obesity in patients with type 2 diabetes. However, the duration of diabetes or HbA1c are not related to HH. Furthermore, recent data show that HH is not associated with type 1 diabetes. C-reactive protein concentrations have been shown to be elevated in patients with HH and are inversely related to plasma testosterone concentrations. This inverse relationship between plasma free testosterone and C- reactive protein concentrations in patients with type 2 diabetes suggests that inflammation may play an important role in the pathogenesis of this syndrome. This is of interest since inflammatory mechanisms may have a cardinal role in the pathogenesis of insulin resistance. It is also relevant that in the mouse, deletion of the insulin receptor in neurons leads to HH in addition to a state of systemic insulin resistance. It has also been shown that insulin facilitates the secretion of gonadotrophin releasing hormone (GnRH) from neuronal cell cultures. Thus, HH may be the result of insulin resistance at the level of the GnRH secreting neuron. Low testosterone concentrations are also related to an increase in total and regional adiposity. This review discusses these issues and attempts to make the syndrome relevant as a clinical entity. Clinical trials are required to determine whether testosterone replacement alleviates insulin resistance and inflammation. In addition, low testosterone levels are associated with an increase in cardiovascular events. Testosterone therapy may therefore, reduce cardiovascular risk. This important aspect requires further investigation.

Dietary calcium intake - a critical reappraisal.

The clinical implications of calcium deficiency include rickets, poor bone mass accrual as well as abnormal foetal programming during pregnancy, poor peak bone mass due to poor accrual in childhood and adolescence, postmenopausal osteoporosis and osteoporosis of the elderly. Serum calcium is maintained within a narrow normal range, chiefly by resorption from the skeleton and alteration of urinary calcium loss and absorption from gut. Absorption is dependent on vitamin D sufficiency, presence of calcium binders in diet (such as phosphate, oxalate and phytate), age group and physiological state. A 2004 WHO expert panel has examined available data on calcium balance studies as well as calcium deficiency states and recommended daily calcium intake in the adult to be 1000 mg per day, with adjustments suggested for other age groups and physiological states. Daily calcium intake in India, both the reality and the recommendations, are far lower than the Western data. A reappraisal of dietary calcium recommendations may be necessary for India.

Prevalence & risk factors of pre-hypertension & hypertension in an affluent north Indian population.

BACKGROUND & OBJECTIVES: Urban Indians have a high prevalence of insulin resistance, hypertension and cardiovascular disease. We studied the prevalence of pre-hypertension and hypertension, as well their association with cardiovascular risk factors, in a north Indian upper socio-economic population. METHODS: A total of 1746 adults (age >or=30 yr) residing in an urban colony of high-income group residents in the city of Lucknow, north India, were invited to be enrolled for the study. The response rate was 64 per cent (n=1112). Blood pressure, anthropometry, plasma glucose in response to oral glucose tolerance test and lipids were measured. The variables contributing significantly to pre-hypertension and hypertension were analyzed by multiple logistic regression analysis. RESULTS: The age and sex adjusted prevalence of hypertension was 32.2 per cent and pre-hypertension was 32.3 per cent. In contrast to hypertension, which was highest in the age group 60-69 yr (64%), prehypertension was highest (36%) in the group 30-39 yr. There was a high prevalence of cardiovascular risk factors in the general population [central obesity (86.7%), elevated LDL cholesterol (22.8%), abnormal glucose tolerance (41.6%) and smoking (20.3% of males)]. Two or more of the cardiovascular risk factors were present in a higher proportion of hypertensive [66%, odds ratio (OR) 3.0, P<0.0001] and pre-hypertensive, (56%, OR 2.0, P<0.0001) compared to normotensive subjects (39%). Subjects with pre-hypertension had body mass index, waist-hip ratio and frequency of glucose intolerance, which was intermediate between normotensive and hypertensive subjects. In multiple logistic regression analysis, increasing age, body mass index, waist hip ratio and impaired glucose tolerance/diabetes were independent risk factors for both hypertension and pre-hypertension. INTERPRETATION & CONCLUSION: A high prevalence of pre-hypertension and hypertension were noted in affluent urban north Indians. Increasing age, body mass index, central obesity and impaired glucose tolerance/diabetes were significantly associated with both hypertension and pre-hypertension. Pre-hypertension was associated with an increased prevalence of cardiovascular risk factors.
