Sarcoidosis is an inflammatory disease with multisystem involvement characterized by the presence of noncaseating granulomas. It can affect virtually every organ of the body, with lung involvement being most common occurring in >90% of patients. Other organs affected are skin, eye and liver. Skin involvement is common, affecting 25-35%. Here we present a rare case of a 15 year-old male with isolated oculocutaneous sarcoidosis without systemic involvement.

We report a case of 19 year-old female patient diagnosed as systemic lupus erythematosus (SLE) presented with fever and diffuse cutaneous lesions. During the hospital stay she had acute pneumonia, pleural effusion and respiratory failure, which required intensive care unit (ICU) care and mechanical ventilator support. A fulminant course of the disease, decreased values of complement levels and positive antinuclear antibodies (ANA) in pleural fluid and repeated negative sputum for acid-fast bacillus, blood cultures enabled diagnosis of fulminant lupus pneumonitis. Fulminant lupus pneumonitis is a rare but potentially life threatening complication of SLE. Management requires involvement of multiple specialties and rigorous efforts in reviving the patient.

ABSTRACT Thyroxine and triiodothyronine regulate the basal metabolic rate of all cells, including hepatocytes, and thereby, modulate hepatic function. Thus, thyroid dysfunction may perturb liver function. Though a wide spectrum of hepatic abnormalities has been attributed to hyperthyroidism with or without complications, such abnormalities are rare to be found and require high index of suspicion. In this case report, we present a female patient who was admitted with the complaints of generalised weakness, jaundice and shortness of breath. She initially had clinical presentation similar to that of congestive cirrhosis, but eventually proved to be a case of hyperthyroidism leading to hepatic dysfunction.

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, characterized by an autoantibody response to various nuclear and cytoplasmic antigens. Renal disease in SLE occurs in 40-75% of patients, most often within five years of onset of disease, and is one of the strongest predictors of a poor outcome. A hallmark of glomerular involvement in lupus nephritis is the presence of autoantibodies against double-stranded DNA (dsDNA). Its level usually correlates with disease activity. Our patient presented with a rash resembling malar rash and features of nephrotic syndrome. On investigating, patient was found to have pancytopenia, raised erythrocyte sedimentation rate and depressed serum C3 levels with positivity of antinuclear antibodies and anti- Ro antibodies. However, most of the markers of lupus nephritis including anti dsDNA antibody were negative. Renal biopsy showed features of lupus nephritis (class-IV). Differential item functioning studies showed a full house immunoflourescence staining pattern characteristic of lupus nephritis. Association of Anti-Ro antibody alone with lupus nephritis is less known in literature. Negativity of anti-dsDNA antibody, which is usually considered to be diagnostic of lupus nephritis, poses a diagnostic dilemma short of renal biopsy. Till date only very few cases of non-drug induced lupus nephritis with negative dsDNA antibodies have been reported. In this report we wish to highlight a case of lupus nephritis which was negative for its specific anti dsDNA antibodies and with possible role of anti-Ro antibodies in the pathogenesis of lupus nephritis although the underlying mechanism is incompletely understood.

Neurocysticercosis (NCC), a disease caused by the larval form of the pork tapeworm , is a common cause of acquired epilepsy globally, especially in areas with poor sanitation. While seizures and headaches are common manifestations, cases of NCC leading to monoparesis are exceedingly rare. Here, we describe a distinctive case of a 42-year-old male who developed sudden weakness and spasms in his left hand without prior injury or other systemic symptoms. Magnetic resonance imaging (MRI) of the brain revealed a single cystic lesion in the right frontoparietal lobe indicative of NCC, which was the cause of his pure motor monoparesis (PMM), without any sensory loss. Treatment with dexamethasone and albendazole substantially improved his motor abilities, highlighting the necessity of considering NCC in differential diagnoses for monoparesis, particularly in endemic areas. This case adds a unique perspective to the clinical spectrum of NCC, highlighting the critical role of prompt and accurate diagnosis followed by appropriate treatment in achieving favorable outcomes.

Background: Protein-energy wasting (PEW) is common in patients with chronic kidney disease (CKD), and is associated with high morbidity and mortality. Malnutrition-Inflammation Score (MIS) has significant correlations with prospective hospitalization and mortality, as well as measures of anemia, inflammation, and nutrition in dialysis patients.Material and Methods: The study was conducted on 100 adult patients of CKD selected from K&D clinic PGIMS, Rohtak. All the patients went under detailed socioeconomic, clinical, biochemical and radiological examination. The average of three measurements of body weight, height, triceps skin fold thickness (TST), and mid-arm muscle circumference (MAMC) were measured in all patients. MIS was calculated for all the patients.Results: Out of total 100 patients, 64 were male and 36 were female. Overall, the prevalence of malnutrition was 60%. A total of 42%, 16% and 2% patients had mild, moderate and severe malnutrition respectively. Our study also shows significant association between staging of CKD (3 to 5-D) and MIS. A significant negative correlation was found between MIS and factors such as BMI, eGFR, serum calcium and hemoglobin levels. A significant positive correlation of this score was found with blood urea serum creatinine, serum uric acid, serum potassium and serum phosphate. Multivariate analysis showed significant association between MIS and serum albumin, TIBC, BMI, family income and hs-CRP.Conclusion: Assessment of key components of malnutrition and inflammation early in disease course will help to identify high risk subjects in whom modifying these predictors will help in providing active and healthy life for CKD patients.

Background: Chronic kidney disease (CKD) is an emerging health problem in both developed and developing countries. Depression, anxiety and sleep disturbances are highly prevalent in patients with chronic disease, but remain undertreated despite significant negative consequences on patients’ health. Assessment of key components of mental health early in disease course will help to identify high risk subjects in whom modifying these predictors will help in providing active and healthy life in CKD patients.Methods: We did a cross sectional study in 200 patients of CKD stage III to V-D fulfilling the eligibility criteria who were on follow up in a single tertiary care center in the state of Haryana, India. We assessed the prevalence of anxiety, depression and insomnia and their correlation with demographic variables in these patients. The structured questionnaire used in this study gathered information on respondent demographic and disease characteristics, and information obtained from the HADS and PSQI questionnaire. Factors associated with anxiety, depression and insomnia were examined by a multiple logistic regression analysis.Results: The prevalence of anxiety, depression and insomnia were found to be 71%, 69% and 86.5% respectively. As the CKD stage advanced, the prevalence as well as severity of these parameters increased. Anxiety, depression and sleep quality were found to be significantly correlated to unemployment, low income, low education, urban residence and presence of co-morbidities. The anxiety, depression and insomnia scores were found to have a strong negative correlation with eGFR, hemoglobin, serum calcium (p <0.01) and a positive correlation with TLC, blood urea, serum creatinine and serum phosphate (p <0.05).Conclusion: We observed a high prevalence of anxiety, depression and insomnia in CKD patients. There is a need to develop strategies to accurately identify “high risk” subjects who may benefit from preventive measures before complications occur. By identifying CKD patients with high risk of developing these mental health related issues, healthcare provider may be better able to ensure the provision of appropriate rehabilitation to this population.

The tropical areas are a home to a number of diseases because of the hot & humid climate, and lack of health care facilities. Tropical Nephropathies are a major health problem and a matter of great concern. The main causes of kidney injury in tropics are due to bacterial, viral or parasitic infections like malaria, dengue, leptospirosis, scrub typhus, acute gastroenteritis, tuberculosis, leprosy and toxic envenomations like snake bite. Renal injury associated with tropical infections has a wide spectrum of presentations ranging from acute kidney injury to chronic kidney disease. Renal involvement in infectious diseases by one or other mechanism is a definite cause of increased morbidity and mortality. Proper understanding of these diseases, early diagnosis, patient education and improved health care facilities will lead to a better outcome and improved survival. This article reviews the various tropical infections causing kidney injury including pathophysiology and line of management.

Due to its broadband optical absorption and advancement in wafer-based processing technology, silicon is extensively employed in photovoltaic devices. However, the application of silicon for photoelectrochemical reactions in its wafer/bulk form is limited and has consistently demonstrated inadequate photoelectrochemical performance. This Review offers a critical summary on light-induced H 2 production, CO 2 reduction, NH 3 formation via nitrate or N 2 reduction and biomass valorization using silicon nanostructures. In these photoelectrochemical applications, how nanostructuring of silicon and tuning its optoelectronic/surface properties impact the performance is emphasized. Elucidating such a comprehensive correlation offers key insights into harnessing the true potential of silicon as a photoelectrode towards solar fuel production. In addition, emerging opportunities and strategies in designing silicon nanostructures-based photoelectrodes for light-driven single-atom catalysis and overall water splitting reactions are provided. While silicon is widely used in photovoltaic devices, its use in applications that require photoelectrochemical reactions is constrained. This Review discusses the use of silicon for light-induced production of hydrogen, carbon dioxide, ammonia, and for biomass valorization, with a focus on nanostructures and tuning optoelectronic and surface properties.

Peripheral bone density measurements are scarce and the factors, which predict bone mineral density at these sites, especially in children, are not clearly known. In this study, age, height, weight and alkaline phosphatase had a significant association on peripheral bone mineral density in healthy Indian school girls. Factors that lead to the attainment of peak bone mass at peripheral sites, during period of growth are not clearly known. Six-hundred and sixty-four randomly selected 7- to 17-year-old girls from upper and lower socioeconomic status (USES/LSES) schools were assessed clinically and a recording of their height and weight was undertaken. Serum calcium, phosphorus, total alkaline phosphatase (ALP), 25-hydroxyvitamin D (25-OHD) and parathyroid hormone (PTH) were measured in all of them. Bone mineral density (BMD) was measured at the distal forearm (BMDdf) and calcaneum (BMDca) by peripheral dual energy X-ray absorptiometry (pDXA). Girls belonging to the USES were significantly taller (149.7 +/- 12.3 cm vs 144.4 +/- 11.9 cm; P < 0.001) and weighed more (44.3 +/- 12.9 kg vs 35.9 +/- 10.0 kg; P < 0.001) than girls from the LSES. USES girls had a significantly higher mean serum calcium (9.3 +/- 0.7 mg/dl vs 9.2 +/- 0.8 mg/dl; P < 0.05) and significantly lower alkaline phosphatase (316 +/- 166 IU/l vs 423 +/- 228 IU/l; P < 0.01) and iPTH (29.9 +/- 18.4 pg/ml vs 45.7 +/- 64.6 pg/ml; P < 0.01). There was no significant difference in mean serum phosphorus and 25-OHD levels between the two groups. USES subjects had higher BMD at both sites than LSES subjects. BMDdf and BMDca increased with age and tended to plateau by 16 years and 12 years of age respectively in both the groups. Age, height and weight explained approximately 50% of the variability, while biochemical parameters explained approximately 30% of variability in BMD at both the sites. The only biochemical parameter which had a significant association with BMD was ALP at the distal forearm. In conclusion, age, nutrition, height and weight are significantly associated with BMD at peripheral sites.
