Optical Coherence Tomography-Based Diagnosis and Monitoring of Systemic Lupus Erythematosus-Associated Choroidopathy.

A 55-year-old female presented with bilateral lower limb swelling and facial swelling along with a decreased frequency of micturition. Baseline investigations revealed an elevated serum creatinine and blood urea nitrogen. Subsequent investigations revealed a positive antinuclear antibodies (ANA) +++ (titer 1:10,000, serum immunofluorescence method) and positive anti-double-stranded DNA (dsDNA) testing. A detailed ophthalmic evaluation was performed. Her visual acuity was 6/36 improving to 6/18 in either eye. The near vision was found to be N36 without any further improvement. A dilated fundus examination revealed multiple yellowish lesions throughout the posterior pole consistent with pockets of subretinal fluid in the right eye. A swept-source optical coherence tomography (OCT) was performed that revealed the presence of fluid in both the intraretinal and subretinal spaces. A bacillary layer detachment, with the accumulation of fluid in the intraretinal space, was noted. Similar fundus findings were seen in the left eye. A decision was made to employ plasmapheresis (PLEX) along with her routine thrice-weekly hemodialysis. Additionally, the systemic steroids were continued. At her third follow-up (day 22), her vision had improved to 6/9 unaided bilaterally and to N6 with the appropriate correction. There was a near-complete regression of the exudative retinal detachments bilaterally with pigmentary changes. The OCT scans revealed significant regression of the serous retinal and retinal pigment epithelium (RPE) detachments with a thin rim of residual subretinal fluid. Fundus examination and OCT studies established the diagnosis of systemic lupus erythematosus (SLE) choroidopathy and guided its further management with systemic immunosuppression, hemodialysis and plasmapheresis. There was a rapid resolution of the retinal and choroidal findings with visual recovery over the next month.

Impact of diabetic retinopathy on pulse wave analysis-derived arterial stiffness and hemodynamic parameters: A cross-sectional study from Gujarat, India.

PURPOSE: Type 2 diabetes mellitus (T2DM) is known to produce diabetic retinopathy (DR). Pulse wave analysis (PWA) provides arterial stiffness (AS) and central hemodynamic (CH) parameters. We studied the effect of DR on AS and CH parameters in type 2 diabetics (T2D). METHODS: We performed a cross-sectional study on 47 T2Ds attending a private ophthalmology clinic screened for DR by optical coherence tomography angiography and divided into NDR (non-DR), NPDR (non-proliferative DR), and PDR (proliferative DR). Mobil-o-graph (IEM, Germany) based oscillometric PWA yielded AS and CH parameters. They were further compared between groups stratified by DR with P value set at 0.05. RESULTS: Participants had a mean age 62, mean diabetes duration 9 years, high mean BMI, and high prevalence of physical inactivity, hypertension, and poor diseases control. Significant differences were lacking in NPDR, NDR, and PDR in rate pressure product (mean 112.71 vs 116.06 vs 119.57), central pulse pressure (mean 46.50 vs 43.09 vs 42.72), stroke work (mean 153.36 vs 132.36 vs 146.08), augmentation index (mean 29.43 vs 33.14 vs 31.64), and aortic pulse wave velocity (mean 10.06 vs 9.08 vs 9.06). There was no clear pattern of distribution of most parameters among the three subgroups. CONCLUSION: We found a lack of association between DR and cardiovascular ageing studied by AS and hemodynamic parameters. It suggests a possible difference in risk factors for both of these aftermaths of T2DM and calls for further prospective studies with a large sample size.

Effect of Menopause on Arterial Stiffness and Central Hemodynamics: A Pulse Wave Analysis-Based Cross-sectional Study from Gujarat, India.

BACKGROUND: Menopause, a cardiovascular risk in mid-life women, is studied in terms of blood pressure mostly. Arterial stiffness (AS) and central hemodynamics (CH) are direct surrogates measured by pulse wave analysis (PWA) with no study from our region. OBJECTIVE: We studied AS, CH in relation to menopause using PWA. MATERIALS AND METHODS: A cross-sectional study was performed in 134 middle-aged females divided into groups with or without menopause. Oscillometric PWA done by Mobil-o-Graph (IEM, Germany) gave - AS like augmentation pressure, augmentation index at heart rate (HR) 75, aortic pulse wave velocity (aPWV), and total AS pulse pressure amplification; CH like aortic blood pressure, cardiac output and related parameters, peripheral resistance, stroke work, prevalent brachial/central hypertension, and raised central pulse pressure. They were further compared between groups, in relation to body mass index (BMI) and by multiple regressions with P < 0.05 as statistical significance. RESULTS: Postmenopausal women were significantly elder, physically inactive with comparable BMI and showed higher AS (only aPWV was significantly different) and CH. BMI was unrelated to AS or CH in postmenopausal group. Age (except for aPWV), BMI, and HR (except for AIx@75) were insignificant predictors, while systolic blood pressure (SBP) in premenopausal and diastolic blood pressure (DBP) in postmenopausal group was major AS predictors. Age, HR, and BMI were insignificant predictors, while SBP more than DBP was significant predictors of CH. CONCLUSIONS: In obese, predominantly sedentary midlife Gujarati women, menopause negatively affects AS and hemodynamics, central more than peripheral. Menopause accelerates cardiovascular aging, independent of BMI, and age that calls for further studies.

Impact of National Economy and Policies on End-Stage Kidney Care in South Asia and Southeast Asia.

BACKGROUND: The association between economic status and kidney disease is incompletely explored even in countries with higher economy (HE); the situation is complex in lower economies (LE) of South Asia and Southeast Asia (SA and SEA). METHODS: Fifteen countries of SA and SEA categorized as HE and LE, represented by the representatives of the national nephrology societies, participated in this questionnaire and interview-based assessment of the impact of economic status on renal care. RESULTS: Average incidence and prevalence of end-stage kidney disease (ESKD) per million population (pmp) are 1.8 times and 3.3 times higher in HE. Hemodialysis is the main renal replacement therapy (RRT) (HE-68%, LE-63%). Funding of dialysis in HE is mainly by state (65%) or insurance bodies (30%); out of pocket expenses (OOPE) are high in LE (41%). Highest cost for hemodialysis is in Brunei and Singapore, and lowest in Myanmar and Nepal. Median number of dialysis machines/1000 ESKD population is 110 in HE and 53 in LE. Average number of machines/dialysis units in HE is 2.7 times higher than LE. The HE countries have 9 times more dialysis centers pmp (median HE-17, LE-02) and 16 times more nephrologist density (median HE-14.8 ppm, LE-0.94 ppm). Dialysis sessions >2/week is frequently followed in HE (84%) and <2/week in LE (64%). "On-demand" hemodialysis (<2 sessions/week) is prevalent in LE. Hemodialysis dropout rates at one year are lower in HE (12.3%; LE 53.4%), death being the major cause (HE-93.6%; LE-43.8%); renal transplants constitute 4% (Brunei) to 39% (Hong Kong) of the RRT in HE. ESKD burden is expected to increase >10% in all the HE countries except Taiwan, 10%-20% in the majority of LE countries. CONCLUSION: Economic disparity in SA and SEA is reflected by poor dialysis infrastructure and penetration, inadequate manpower, higher OOPE, higher dialysis dropout rates, and lesser renal transplantations in LE countries. Utility of RRT can be improved by state funding and better insurance coverage.

Anaesthesia concerns and perioperative management in a child with DiGeorge syndrome with corrected tetralogy of Fallot with pulmonary atresia posted for laparoscopic orchidopexy: Case report.

DiGeorge syndrome is afflicted with multiple congenital anomalies such as conotruncal and craniofacial anomaly, immune system dysfunction and hypoplasia/aplasia of parathyroid glands. Laparoscopy is a preferred surgical approach over open orchidopexy due to better visualisation of impalpable testis avoiding long incision, minimal tissue damage and a faster recovery. We report a case of DiGeorge syndrome with corrected tetralogy of Fallot with pulmonary atresia in a 1-year-old male child posted for laparoscopic orchidopexy. The anaesthesiologists face unique challenges due to the multisystem involvement and the effects of laparoscopic surgery on multiple organs. Thorough understanding of DiGeorge syndrome is essential for a good perioperative outcome.

Effectiveness and Safety of Camylofin in Augmentation of Labor: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis assessed the effectiveness and safety of camylofin compared with other antispasmodics (drotaverine, hyoscine, valethamate, phloroglucinol, and meperidine) in labor augmentation. A systematic literature search until March 27, 2018, was performed, and data on the cervical dilatation rate (CDR) and duration of stages of labor reported in 39 eligible articles were analyzed using a random-effects model. CDR was significantly higher (0.38 cm/h, 95% confidence interval (CI) 0.10 to 0.67, p = 0.007), and the duration of the first stage of labor was significantly shorter (- 41.21 minutes, 95% CI, - 77.19 to - 5.22, p = 0.02) in women receiving camylofin than those receiving other antispasmodics for labor augmentation. CDR was significantly higher with camylofin compared with valethamate (0.6 cm/h, 95% CI 0.4 to 0.9, p < 0.0001) and hyoscine (20 mg) (0.5 cm/h, 95% CI 0.1 to 0.8, p = 0.02). The duration of the first stage of labor was significantly shorter with camylofin compared with hyoscine (20 mg) (- 59.9 min, 95% CI, - 117.9 to - 1.8, p = 0.04). However, CDR and the duration of first stage of labor were not statistically different between camylofin and drotaverine groups. The percentage of women having nausea and vomiting, cervical/vaginal tear, and postpartum hemorrhage were comparable with all antispasmodics, whereas tachycardia was least reported in women receiving camylofin (3, 2.07%) than those receiving other antispasmodics. This meta-analysis demonstrated the benefit of camylofin in labor augmentation with a faster CDR and reduction in the active first stage of labor in Indian women.

Association of brachial and central hemodynamic parameters to eGFR and proteinuria in Gujarati diabetics with mild-to-moderate nephropathy.

INTRODUCTION: Diabetes mellitus (DM) is a significant risk factor for nephropathy and cardiovascular morbidity. Pulse wave analysis (PWA) gives direct inference of brachial hemodynamics (BH) and central hemodynamics (CH). We studied relation of them with diabetic nephropathy (DN) among type-2 diabetics (T2D). METHODS: We studied oscillometric PWA by a cross-sectional study in 160 T2Ds. Using Mobil-o-Graph (IEM, Germany), we derived BH (blood pressure, pulse pressure index, rate pressure product) and CH (aortic pressure, cardiac index, stroke volume index, stroke work). They were further compared and associated with DN in terms of creatinine, proteinuria, and estimated glomerular filtration rate (eGFR). RESULTS: There were 89 males, mean age 56 years, mean duration 4.8 years, 80% hypertensive predominantly using ACE inhibitors, poor glycemic blood pressure (BP) control, mainly mild-to-moderate DN, mean eGFR 88.2, 34% prevalence of proteinuria. Arterial stiffness was high with female disadvantage. BH and CH parameters were not different with or without DN using proteinuria or eGFR (60 cutoff) criteria. BH, CH correlated insignificantly with creatinine and eGFR. Female disadvantage, correlation with bSBP and aSBP were only significant results. CONCLUSIONS: BH and CH are not related to eGFR and proteinuria in predominantly hypertensive, Gujarati diabetics with mild-to-moderate nephropathy suggesting need of other cardiovascular parameters.

Central hemodynamics and arterial stiffness by oscillometric pulse-wave analysis in treated Gujarati euglycemic hypertensives: A case-control study.

INTRODUCTION: Hypertension is the most prevalent noncommunicable disorder, studied in terms of brachial blood pressure. Direct parameters like central hemodynamics and arterial stiffness, though superior, are not studied much. The same can be studied by pulse-wave analysis (PWA) and we did that in euglycemic treated hypertensives. MATERIALS AND METHODS: A case-control study was conducted in 258 treated euglycemic hypertensives and 258 matched controls. Oscillometric PWA was accomplished by Mobil-O-Graph (IEM, Germany). Parameters were further analyzed for the effect of gender, physical activity, body mass index (BMI) (cutoff 23), blood pressure control, and duration (cutoff 5 years). Multiple linear regressions were used to find significant predictors. P < 0.05 was taken as statistically significant. RESULTS: Cases had significantly higher brachial arterial parameters (blood pressure, heart rate, rate pressure product), arterial stiffness (augmentation pressure, augmentation index, pulse-wave velocity, total arterial stiffness, pulse pressure amplification), and central hemodynamics (central blood pressure, cardiac output, stroke work) compared to age, gender, and BMI-matched controls. In the case group, female gender, BMI ≥ 23, and uncontrolled blood pressure were significant factors affecting results. Heart rate and pulse pressure were major predictors of study parameters. Central pressure parameters were not predicted significantly by corresponding brachial pressure parameters. CONCLUSION: PWA revealed the adverse profile of arterial stiffness and central hemodynamics in treated Gujarati hypertensives, associated with female gender, BMI, and blood pressure control, predicted mainly by heart rate and pulse pressure, independent of brachial blood pressure. It indicates both potential and further study of these parameters.

Central hemodynamics and arterial stiffness in Gujarati diabetics not receiving any antihypertensive: A case-control study based on oscillometric pulse wave analysis.

INTRODUCTION: Diabetes is a modern epidemic imposing significant cardiovascular risk. Immediate and discrete parameters such as arterial stiffness and central hemodynamics are studied scarcely. Pulse wave analysis (PWA) offers noninvasive measurement of the same and we performed that in diabetics. MATERIALS AND METHODS: We performed a case-control study on 148 treated diabetic not on antihypertensive and 148 nondiabetic normotensive controls. Oscillometric PWA was performed by Mobil-O-Graph (IEM). Parameters were further analyzed for effect of gender, physical activity, body mass index (BMI; cut-off 23), glycemic control, and disease duration (cut-off 4 years). Multiple linear regressions were used to find significant predictors. P <0.05 was taken as statistical significance. RESULTS: Cases had significantly raised brachial hemodynamics (blood pressure, heart rate, rate pressure product), arterial stiffness (augmentation pressure, augmentation index, pulse wave velocity, total arterial stiffness, pulse pressure amplification), and central hemodynamics (central blood pressure, cardiac output, stroke work) than controls. In the case group, female gender, BMI ≥ 23, and physical inactivity were the significant factors affecting results (arterial stiffness more than central hemodynamics); glycemic control and duration were not. Heart rate was the major predictor of study parameters. Brachial pressure parameters were not significant predictors of corresponding central pressure parameters. CONCLUSION: Gujarati diabetics not using any antihypertensive had adverse profile of beyond brachial blood pressure discrete cardiovascular parameters, independent of duration and glycemic control, related to gender, BMI, and physical activity, indicating vascular progeria in the absence of hypertension. This baseline study suggests further work on these potential parameters.

Abnormal sympathetic functioning is linked to familial hypertension in nonathletic young males.

BACKGROUND: Sympathetic overactivity mediates abnormal cardiovascular outcome that is affected by stress, lack of physical activity (PA), and familial hypertension (HTN). It can be assessed by blood pressure-based sympathetic function tests. OBJECTIVE: We studied sympathetic function tests in young nonathletic males in relation to measures of obesity, PA, and familial HTN. METHODOLOGY: We recruited 100 males (mean age: 19 years) and measured body mass index (BMI) and body composition parameters by tetrapolar bioelectrical impedance such as total body fat, visceral fat, subcutaneous fat, and skeletal muscle mass. Using instrument cardiac autonomic neuropathy system of Recorders and Medicare System Company, India, blood pressures (supine, standing, and post hand grip) were recorded and studied quantitatively and qualitatively. RESULTS: Physically active and inactive individuals (n = 50 each) had comparable age, BMI, measures of obesity, and sympathetic function tests. However, individuals with familial HTN (n = 37) showed significantly higher obesity measures and blood pressures (supine: systolic blood pressure [SBP] - 133 vs. 115 and diastolic blood pressure [DBP] - 79 vs. 76; standing: SBP - 136 vs. 122 and DBP - 80 vs. 76; post hand grip: SBP - 136 vs. 125 and DBP - 86 vs. 81). Qualitatively, postural hypotension was seen in only two individuals, while worst grading was in post hand grip test significantly and more so in physically inactive group (30%, 28%, and 42% vs. 16%, 20%, and 64%) and individuals with positive familial HTN (32%, 38%, and 30% vs. 17%, 13%, and 70%). CONCLUSION: Familial HTN, but not physical inactivity, affects sympathetic functioning in nonathletic young male medical personnel. It asks for other lifestyle modifications for better cardiovascular health as primary prevention.

Pulse wave analyzed cardiovascular parameters in young first degree relatives of hypertensives.

BACKGROUND: First-degree relatives (FDRs) of hypertensive (HT) are predisposed to hypertension (HTN) which accelerates cardiovascular aging. Same can be studied noninvasively by pulse wave analysis (PWA), encompassing central hemodynamics such as central blood pressure (cBP), cardiac output, and stroke work (SW) and vascular stiffness parameters such as pulse wave velocity (PWV) and augmentation index at HR 75 (AIx@75). We studied PWA-derived cardiovascular parameters in FDRs of HT compared to controls. MATERIALS AND METHODS: We conducted a case-control study in 119 FDRs of HT and 119 matched controls. Oscillometric PWA was performed by Mobil-o-Graph (IEM, Germany) and cardiovascular parameters were compared. P < 0.05 was considered statistically significant. RESULTS: Groups were comparable with gender, age, height, weight, body mass index, and physical activity. FDRs of HT had significantly higher brachial and cBPs, SW (101.41 ± 25.44 vs. 88.31 ± 20.25, P = 0.001), rate pressure product-119.40 ± 25.34 vs. 108.34 ± 18.17, P < 0.0001), PWV (5.22 ± 0.46, P < 0.0001), and AIx@75 (31.48 ± 9.01 vs. 27.95 ± 9.4, P = 0.002) than control. Dependent study variables correlated with brachial blood pressure more in magnitude and significance level than age or anthropometric variables. PWA results of FDR with maternal inheritance did not differ significantly from those with paternal inheritance. CONCLUSION: PWA reveals early cardiovascular aging in young FDRs of HTs. It clues to future cardiovascular disease including HTN itself, need for primary prevention, and further study for consolidation of these results.

Early Screening of Hypertension and Cardiac Dysautonomia in Each Hypertensive is Needed-inference from a Study of QTc Interval in Gujarat, India.

BACKGROUND: Hypertension (HTN) is linked to cardiac dysautonomia that can end up as life-threatening arrhythmias. The same can be screened by simple electrocardiogram (ECG)-based QTc (QT corrected for heart rate) interval which indicates repolarization abnormality. We quantified QTc interval among treated hypertensives in comparison to controls, testing effect of age, gender, and blood pressure. METHODS: We conducted a cross-sectional study was done at a tertiary care teaching hospital of Gujarat, India, on 142 hypertensives on monotherapy (60 males, 82 females) and 72 age-, sex-, and time-matched normotensives. ECG was recorded with minimum 10 complexes of Lead II. QTc was derived from average of 10 values, using Bazett's formula. QTc > 0.43 s in male and > 0.45 s in female was considered abnormal. RESULTS: Hypertensives (mean age 40 and duration 5 years) had significantly higher QTc value than normotensives among males (0.42 vs. 0.40, P < 0.001), females (0.44 vs. 0.41, P < 0.001), and in total (0.43 vs. 0.41, P < 0.001) with 24% prevalence of ECG-based left ventricular hypertrophy. Hypertensives had odds ratio 1.63 in males (P = 0.15), 23.71 in females (P = 0.003), and 3.83 in total (P < 0.001) for prolonged QTc. QTc values were significantly affected by increasing age amongst hypertensives but not by duration of HTN or current blood pressure. CONCLUSIONS: Our study showed a high prevalence of prolonged QTc, both qualitatively and quantitatively, in hypertensives on monotherapy with poor pressure control, associated with female gender and age but not duration or blood pressure. This underscores high risk of repolarization abnormality induced future event, suggesting QTc screening as primary prevention.

Pulse wave analyzed cardiovascular parameters in young first degree relatives of type 2 diabetics- a cross-sectional study.

BACKGROUND: First degree relatives (FDR) of type 2 diabetic (T2D) are predisposed for type 2 diabetes mellitus (T2DM) which accelerates cardiovascular aging. Pulse wave analysis (PWA) gives non-invasive measurement of central hemodynamics like central blood pressure (cBP), cardiac output (CO), stroke work (SW) and vascular stiffness like pulse wave velocity (PWV) and augmentation index at heart rate 75 (AIx@75). OBJECTIVE: To study PWA derived cardiovascular parameters in FDRs of T2D as compared to controls. MATERIALS AND METHODS: We enrolled 117 FDRs of T2D and 117 matched controls for a cross-sectional study. We performed PWA using Mobil-o-Graph (IEM, Germany) by oscillometric method to derive cardiovascular parameters which were compared and correlated for significance. P value less than 0.05 was considered statistically significant. RESULTS: Gender, age, height, weight, body mass index (BMI), physical activity were comparable between groups. FDRs of T2D had significantly higher blood pressure (brachial-systolic 125 vs 118, diastolic 80 vs 77, mean 100 vs 96mmHg and central- systolic 113 vs 105, diastolic 82 vs 79, pulse pressure 31 vs 28mmHg), SW (98 vs 90gm/bt), rate pressure product (RPP- 113 vs 107), PWV (5.14 vs 4.89m/s), AIx@75 (30 vs 27) than control. Dependant variables correlated with brachial BP more than age or anthropometric variables. Result did not differ by maternal or paternal inheritance in case group. CONCLUSIONS: Young, sedentary, non-obese FDRs of T2D have adverse cardiovascular profile which is suggested to worsen before or with onset of T2DM and definitely need attention for life style modification as primary prevention.

Myotarsal flap - a versatile entity for lower eyelid reconstructions.

The purpose is to present a new surgical technique using myotarsal (MT) flap for reconstruction of small to subtotal full thickness defects - up to 8 mm in height - of lower eyelids, without needing concomitant supplementary procedures. MT flap consists of a 3 mm tarsal strip with attached levator complex. It does not have conjunctival lining or pedicle. Versatility of the flap extends to correction of mild to severe ptosis, and retraction of upper eyelids. This is a retrospective personal series of 163 patients, who underwent surgical reconstruction with MT flap overlaid with quilted skin graft (modified myotarsal flap) after excision of malignant tumours of lower eyelid. Surgery was on day case basis under LA. Patients were assessed for aesthetic and functional outcome, and complications. No patient had any complication. Assessment of outcome included corneal and ocular surface health and protection, eye closure, tear secretion, and lid contours. These were aesthetically and functionally satisfactory. Histology confirmed complete tumour clearance, and clinical diagnosis. There was no recurrence of tumour. An astounding, new, unique and original observation of the study is that cornea and ocular surface remained undamaged throughout, despite absence of conjunctival lining of MT flap. This goes against all current tenets of oculoplasty. Use of the modified MT flap is a safe, versatile, and effective procedure yielding satisfactory aesthetic and functional results for reconstruction of the lower eyelid.

A new refined technique for myogenic ptosis correction with resection of myotarsal flap by conjunctival approach.

The purpose is to present a new refined surgical technique for mild-to-severe acquired myogenic ptosis correction under local anaesthesia (LA) as day cases with resection of myotarsal (MT) flap and demonstrate the safety and efficacy of the technique. MT flap consists of 2 mm tarsal strip with attached levator complex - levator muscle, its aponeurosis, and Müller muscle. This is a retrospective personal series of 400+ patients, who underwent surgical correction with MT flap resection of 8-24 mm under LA mostly as day cases. No patient had any complication. Results were satisfactory as assessed on these criteria: (i) elevation of the lid at least above the visual axis; (ii) normal contours of the lid without distortion, with the eyelid conforming to the contours of the globe; (iii) static and dynamic symmetry of upper eyelids; (iv) formation of a normal and symmetrical lid fold; (v) healthy comfortable ocular surface and cornea; and (vi) patient and surgeon satisfaction with the aesthetic outcome. Resection of the MT flap is a safe and effective, microsurgical technique of ptosis correction, yielding satisfactory results without complications, with ergonomic advantages of the inclusion of a tarsal strip. The versatility of the MT flap extends to its use for correction of upper lid retraction, and for formation of the posterior lamina of full thickness small to subtotal lower lid reconstructions.

A cross-sectional study of variations in the biophysical parameters of skin among healthy volunteers.

BACKGROUND: Biophysical parameters of skin such as trans-epidermal water loss (TEWL), hydration, elasticity, pH, and sebum reflects it functional integrity. Advances in technology have made it possible to measure these parameters by non-invasive methods. These parameters are useful for the prediction of disease and its prognosis. It also helps in developing new skin care products according to various skin types, and to evaluate, modify, or compare the effects of existing products. AIM: The aim of the study was to measure, evaluate, and analyze variations in biophysical parameters at pre-selected skin sites in healthy Indian volunteers, across different age groups and gender. METHODS: The study was conducted among 500 healthy Indian volunteers, between 5 and 70 years of age, in the outpatient department of dermatology at Sir T. Hospital, Bhavnagar. Biophysical parameters such as TEWL, hydration, elasticity, and sebum content was measured on four pre-selected body sites by a Dermalab instrument (Cortex Technology, Denmark). The skin pH was measured with a sensitive pH probe (BEPL 2100). RESULTS: All parameters were higher in males compared to females, except for sebum content, which was equal in both genders. Transepidermal water loss and hydration was lower in middle and older age groups. The skin pH showed no statistically significant difference with age. Sebum content was higher in middle and older age groups. The nose had the highest sebum content across all age groups. The forehead showed higher median values of TEWL and hydration compared to other sites. Though elasticity has highest value on forearm, only leg region showed statistically significant value. LIMITATIONS: The present study was confined to a single geographical area, so the effect of environment changes could not be judged accurately. Seasonal variations were not studied as it was a cross-sectional study. CONCLUSION: Skin properties vary with age, gender, and location on the body. This knowledge will help to create a database of these parameters in the Indian population. It would assist in the diagnosis of various clinical conditions and monitor therapeutic response.

Knowledge, attitude, and practice of urban Gujarati type 2 diabetics: Prevalence and impact on disease control.

CONTEXT: Type 2 diabetes is the modern epidemic wherein patient care needs multiple approaches, education, and self-awareness being one of them. There are some knowledge, attitude, and practice (KAP) studies from India but very few relating it with disease control. AIMS: We tried to study KAP of treated type 2 diabetics and its correlation with glycemic control. SETTINGS AND DESIGN: Cross-sectional KAP study. SUBJECTS AND METHODS: We formulated KAP questionnaires in the form of KAP - 10 points for each and total 30. We recruited 200 type 2 diabetics (96 males, 104 females) treated by MD physicians with known current glycemic status. They were asked KAP questionnaires one to one by a direct interview in local language and results were associated with various factors and glycemic control. RESULTS: KAP score on was average 19 out of 30 in type 2 diabetics having mean age 58 years, mean duration 9 years. KAP score was unaffected by gender, occupation, duration of disease but significantly affected by current age, and education level. Only 40% patients had good glycemic control who scored better KAP than poor glycemic. There was positive correlation between KAP score and glycemic control, with significance for only glycosylated hemoglobin and not fasting blood sugar, postprandial blood sugar. CONCLUSIONS: Physician treated type 2 diabetics of our region had moderate KAP score, affected by age, education which suggested to affect glycemic control. Lacunae in knowledge regarding incurability of disease, attitudes toward complication, self-care, and good practices like walking, enriching knowledge need improvement so as an optimum glycemic control.

Comparative study of cardiac autonomic status by heart rate variability between under-treatment normotensive and hypertensive known type 2 diabetics.

BACKGROUND: Co-existence of hypertension is known in three quarter of Indian type 2 diabetics, this duo having adverse additive effect on cardiovascular health including dysautonomia. Latter can be measured by simple 5min heart rate variability (HRV) using simple electrocardiogram, which if reduced indicates cardiac risk. OBJECTIVE: We compared HRV parameters between hypertensive and normotensive type 2 diabetics, looking for significant difference if any. MATERIALS AND METHODS: 98 hypertensive and 40 normotensive type 2 diabetics treated as outpatients were evaluated for disease control and risk stratification. Fivemin resting HRV was measured by Variowin HR, software based instrument, using standard protocols to record time domain, frequency domain and Poincare plot parameters. They were compared between groups for difference. RESULTS: Mean age was 56 and 51 years, duration 6 years and 4 years respectively in hypertensive (HT) and normotensive (NT) group of type 2 diabetics, which did not significantly differ in distribution of risk factors. There was poor glycaemic control (one third) in both groups and good pressure control in HT group. Both groups revealed all reduced HRV parameters with significant difference in-between only for LF/HF ratio (1.29 in HT vs 2.61 in NT group). CONCLUSION: Our findings of HRV suggest that in type 2 diabetics with poor glycaemic and good pressure control, hypertension as a co-existing factor does not make significant difference in cardiac dysautonomia emphasizing residual risk despite antihypertensive treatment and need for early HRV screening, strict glycaemic control and other interventions.

Impact of disease control and co-existing risk factors on heart rate variability in Gujarati type 2 diabetics: An observational study.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a proven threat of cardiac dysautonomia with paucity of studies from India. Poor disease control makes it further worse with co-existence of hypertension in majority. Heart rate variability (HRV) is a validated noninvasive tool to assess cardiac autonomic status. AIM: We studied HRV parameters of type 2 diabetics looking for effects of disease control and other co-existing risk factors. MATERIALS AND METHODS: Ninety-eight hypertensive and forty normotensive under-treatment, Gujarati type 2 diabetics were evaluated for disease control and risk stratification. Five minutes resting, HRV was measured by Variowin HR, software-based instrument, using standard protocols to record time domain, frequency domain, and Poincare plot HRV parameters. They were compared between subgroups for the difference with P < 0.05 defining statistical significance. RESULTS: All HRV parameters were reduced in type 2 diabetics, having mean age 56 years, mean duration 6 years with poor glycemic but comparatively better pressure control. HRV parameters were significantly not different in good compared to poor glycemics or in subjects with optimum pressure control than those without it. Results did not differ significantly, by the presence of individual cardiovascular risk factor in diabetics except resting heart rate. CONCLUSION: Our findings of HRV suggest that type 2 diabetics with poor glycemic control do not have a significant difference of cardiac dysautonomia by pressure control, glycemic control, and absence of risk cardiovascular factor. It suggests diabetes as a major cause for cardiac dysautonomia, residual risk despite treatment and need for HRV screening, strict glycemic control, and further studies.
