Insulin secretory actions of polyphenols of <i>Momordica charantia</i> regulate glucose homeostasis in alloxan-induced type 2 diabetic rats

Objective Momordica charantia, commonly known as bitter gourd, is traditionally used as remedies for various diseases including diabetes. The main objective of this study is to investigate the in vitro and in vivo insulinotropic and anti-diabetic effects of an 80% ethanolic extract of Momordica charantia (EEMC) fruit, as well as the underlying molecular mechanism involved and preliminary phytochemical screening. Methods The insulin secretion was measured using clonal pancreatic BRIN-BD11 β-cells and isolated mouse islets. The ability of EEMC to inhibit carbohydrate digestive enzymes and glucose absorption and, scavenge free radicals were assessed via starch digestion, glucose diffusion and DPPH assay methods. The effects of EEMC on a variety of metabolic parameters were evaluated in alloxan-induced type 2 diabetic rats, including lipid profile. Finally, a preliminary phytochemical screening was conducted to identify the active phytoconstituents. Key findings EEMC increased insulin release through the KATP-dependent/cAMP pathway, which depolarizes the β-cell membrane and elevates intracellular calcium. It also inhibited glucose absorption and free radicals, suggesting its potential to delay gastric emptying, attenuate oxidative stress, and reduce inflammatory cytokines. In vivo studies showed that EEMC improves oral glucose tolerance, food intake, fasting blood glucose, plasma insulin, lipids, and promotes intestinal motility. The active phytoconstituents in EEMC, such as flavonoids, alkaloids, tannins, saponins, steroids, and glycosides, are likely responsible for these effects. Conclusion The antihyperglycemic properties of EEMC indicate that it might be a promising candidate for diabetes management. However, additional study into the application of Momordica charantia in type 2 diabetes is essential

A clinicopathological study of pemphigus in Eastern India with special reference to direct immunofluorescence

Background: Pemphigus is a group of chronic autoimmune vesico-bullous disorders in which the epidermis and the basement membrane zone are the focus of attack resulting in cutaneous and mucosal blister formation. Direct immunofluorescence (DIF) test is a very sensitive test for the diagnosis Aim: To study the clinico histopathological patterns of pemphigus in eastern India. The study also aims to correlate DIF with clinical and histologic findings as well as severity of skin involvement [scoring systems]. Materials and Methods: Total 41 patients were studied over a period of 1 year in the Post-graduate centre of Dermatology in Eastern India. DIF, histopathology and clinical data were correlated. Results: In our study Pemphigus vulgaris (PV) was the predominant type with 32 cases followed by 8 cases of pemphigus foliaceus (PF) and a single case of IgA pemphigus. Mean age at presentation was late middle age. Majority of the patients, 26 (63.41%) initially had cutaneous involvement followed by mucosal involvement. In this study group 36 (87.80%) patients showed acantholytic cells on histopathological examination. Most patients of PV showed suprabasal blister 20 (62.50%) followed by intraspinous 5 (15.62%) and subcorneal 5 (15.62%) blister. In majority 28 (87.50%) of the PV patients IgG and C3 antibodies were deposited throughout the epidermis. The strength of antibody positivity was strong in most of the patients (71.87%). In cases of PF mostly IgG 6 (75%) antibodies were deposited in the upper epidermis. DIF intensity had poor correlation with disease activity/severity except in PF. Conclusion: Almost 85.36% cases of pemphigus were diagnosed clinicopathologically. But 6 cases couldn't be diagnosed accurately on clinicopathological basis and in them DIF was confirmatory. Two cases of pure mucosal PV and 1 case of IgA pemphigus was confirmed by DIF. Two cases of bullous pemphigoid clinico-histologically mimicking PV were also excluded by DIF. So it appears from our study that DIF is confirmatory for diagnosis of pemphigus in all cases

Primary tuberculosis in soft palate: Case report of a rare entity

A 40-year-old male patient presented to our clinic with history of dysphagia and ulceration in the palate for two months. After history-taking and thorough clinical examination, investigations like routine blood parameters, chest skiagram, sputum for acid-fast bacilli, ultrasonography of the abdomen, and biopsy from the palatal lesion were performed. No evidence in support of pulmonary or abdominal tuberculosis was found. Histopathological examination of the biopsy revealed granulomatous inflammation with Langhans giant cells and caseation necrosis. Diagnosis of primary tuberculosis of soft palate was made. Anti- tubercular regimen (CAT I) for 6 months was prescribed, and we got a dramatic response noted within 15 days. As isolated tuberculosis of soft palate is a very rare entity, one should, therefore, consider it in any case of chronic ulcer of the soft palate. Response to CAT 1 was excellent in our case

Pattern Of Non-Venereal Genital Dermatoses In Adult Male- A Clinical Study In A Tertiary Care Centre.: Non-Venereal Male Genital Dermatoses

Objective : Non venereal genital dermatoses are genital dermatoses not sexually transmitted. It causes extreme anxiety in patients, because venereal disease is often patient’s primary concern. Aims were To study the clinical pattern of various non-venereal genital dermatoses of male having age 18 to 60 yrs. Methods and Material: A cross-sectiona lclinical study was done among Male patients between 18-60 years of age, having Non-venereal Genital dermatoses, attending the dermatology O.P.D of a tertiary care hospital in Eastern IndiaPatients clinically diagnosed with Non-venereal Genital Dermatoses were included in the study after signing the Informed consent Thorough examination of genital lesion was done with special relevance to the morphology, number, tenderness, regional lymph node involvement etc. Complete physical andsystemic examination was done. Associated skin lesions were noted.&nbsp;Investigations such as Blood sugar, Tzanck smear, KOH mount, Gram-stain and histopathological examination were done in relevant cases. VDRL, HIV test were done to rule out STD. Statistical analyses were done using necessary software. Results: Total 133 patients were included in the study. The commonest age group was 18 – 30 years. Most common [35%] disease was Candidal Balano-posthitis. Married persons were more affected Diseases predominant in rural areawere LSA.&nbsp; Non-STD genital dermatoses are less commoner in Muslim. Diabetes came as common in both personal and family history Conclusions: For the differentiation of non venereal genital dermatoses, apart from history and investigations the clinical study such as age, residence, religion and morphology of the lesions are very important. Clinician should have an unbiased approach towards genital conditions

Cutaneous Manifestations of Diabetes Mellitus in a Tertiary Care Hospital in Eastern India: A Cross-sectional Study

Background: Diabetes mellitus is a chronic metabolic disorder and is a major public health problem worldwide. Skin diseases can appear as the first sign of diabetes or can develop at any time in the course of the illness. Purpose: This study aimed to determine the pattern and prevalence of skin manifestations in patients with diabetes mellitus.

Candidal balanoposthitis was the most common fungal infection. Limitation: Limited sample in a single center. Conclusion: Infections were more prevalent compared to noninfectious disease in a population with uncontrolled diabetes mellitus. Pruritus was the most common disorder among the other diabetic complications

NEEDLE FREE MONITORING OF BLOOD GLUCOSE THROUGH REVERSE IONTOPHORESIS

The frequent blood glucose monitoring is highly critical in order to understand the progression of diabetes mellitus and to minimize the probabilities of associated complications. This focuses to the fabrication of a new device for individual blood glucose monitoring. However, this technology turned out to be painful owing to its finger-stick technique, resulting in compromised patient compliance and inconsistent results. A paradigm shift from invasive to non-invasive technique to combat the above-stated limitations became an attractive tool for the researchers. The evolution of reverse iontophoresis to extract the essential plasma biomarkers as well as blood glucose through the skin was the result of the extensive efforts of the researchers as a means to monitor the blood glucose levels. The technology utilises delivery of small amount of electric current through the skin to extract the target molecules. This concept has received tremendous attention in the past decade; however, the technology still needs stringent validation for widespread implementation. Thus, in the present review, we aimed to elaborate the underlying mechanism of the reverse iontophoresis technique in the evaluation of blood glucose levels through skin, its unique features and its advancements towards commercialisation, the challenges faced, additional applications and the future prospects. The review also updates about the other non-invasive glucose monitoring techniques in comparison to reverse iontophoresis
