Chronic Kidney Disease and Charcot Neuro-Osteoarthropathy of Foot in Diabetes.

INTRODUCTION: Charcot neuro-osteoarthropathy (CNO) occurs late in diabetes and may cause fracture, deformity, and higher mortality. Diabetic kidney disease (DKD) affects bone metabolism and contributes to mortality. However, there is no data on prevalence of CNO and its outcomes with coexisting DKD (or chronic kidney disease [CKD]). METHODS: To ascertain the prevalence of CKD (pick CKD or DKD) among patients with CNO and delineate the remission of active CNO and subsequent lower extremity amputation and all-cause mortality during prospective follow-up. Consecutive patients with diabetic CNO (active or inactive) were enrolled and subsequently divided into those with and without CKD (pick CKD or DKD) (Group A and Group B, respectively). A preestablished timeframe of 36 weeks was utilized to evaluate the remission proportion of active CNO. RESULTS: A total of 493 CNO patients were observed and 449 subjects (150 patients had active CNO) were further evaluated. The overall prevalence of diabetic nephropathy (DKD or CKD?) CNO was 43.7%. The proportion of patients achieving remission was significantly lower in Group A compared to Group B (OR 0.468, CI [0.239-0.934], P = .025), however, the median time for achieving remission was similar between the 2 groups (14 weeks vs 16 weeks, P = .885). Overall, all-cause mortality was notably higher Group A compared to Group B (OR 2.23, 95% CI [1.474-3.368]) over a median follow-up of 4 years. No significant differences were observed in rates of diabetic foot ulcers (58.2% vs 54.9%; P = .584) and amputations (17.4% vs 15.12%; P = .889) between Group A and Group B. CONCLUSION: Patients of CNO with coexisting CKD have poor prognosis both in terms of likelihood of active CNO remission and higher mortality.

Sheehan's Syndrome in a Patient With Factor XI Deficiency.

Sheehan's syndrome (SS) is a condition characterized by panhypopituitarism that generally occurs after an episode of postpartum bleeding. There are certain hypotheses regarding the development of SS in the postpartum period. Coagulation factor abnormalities have been reported to be associated with SS. Associated hypothyroidism and hypocortisolism have been found to cause coagulation abnormalities. After the correction of the hypothyroidism and hypocortisolism, there is a gradual correction of the coagulation abnormality. In our case, a middle-aged woman presented with recurrent episodes of hospital admission because of generalized weakness and fever. She was found to have a biochemistry profile suggestive of hypopituitarism with preserved gonadal function. Her hemogram was normal, but the coagulogram showed a prolongation of activated partial thromboplastin time with a near-normal prothrombin time. She was evaluated and found to have factor XI deficiency. In the background of excessive vaginal bleeding and hypopituitarism, a diagnosis of SS was made. The presence of factor XI deficiency may have led to excessive bleeding and the development of SS. To the best of our knowledge, there is no reported association of factor XI deficiency with SS in the literature, and this is the first reported case.

Normative data for insulin-like growth factor-1 (IGF-1) in healthy children and adolescents from India.

BACKGROUND: Serum IGF-1 is an important biochemical tool to diagnose and monitor GH-related disorders. However, ethnic-specific Indian data following consensus criteria for the establishment of normative data, are not available. Our objective was to generate chronological age (CA)-, bone age (BA)- and Tanner stage-specific normative data for IGF-1 in healthy Indian children and adolescents. METHODS: A cross-sectional epidemiological study was conducted in schools and the community, which enrolled apparently healthy children and adolescents with robust exclusion criteria. The outcome measure was serum IGF-1 assessed using an electro-chemiluminescence immunoassay (ECLIA). The 2.5th, 5th, 10th, 25th, 50th (median), 75th, 90th, 95th, and 97.5th centiles for IGF-1 were estimated using generalized additive models. RESULTS: We recruited 2226 apparently healthy participants and following exclusion, 1948 (1006 boys, 942 girls) were included in the final analysis. Girls had median IGF-1 peak at CA of 13 years (321.7 ng/mL), BA of 14 years (350.2 ng/mL) and Tanner stage IV (345 ng/mL), while boys had median IGF-1 peak at CA of 15 years (318.9 ng/mL) BA of 15 years (340.6 ng/mL) and Tanner stage III (304.8 ng/mL). Girls had earlier rise, peak and higher IGF-1 values. The reference interval (2.5th-97.5th percentile) was broader during peri-pubertal ages, indicating a higher physiological variability. CONCLUSION: This study provides ethnicity-specific normative data on serum IGF-1 and will improve the diagnostic utility of IGF-1 in the evaluation and management of growth disorders in Indian children and adolescents.

Phosphate: An underrated component of primary hyperparathyroidism.

Primary hyperparathyroidism (PHPT) is a systemic disease that affects all the systems of the body, specifically the bones and the kidneys. Its main action is on calcium homeostasis. It tries to preserve the body's calcium level at the cost of phosphate. The criteria for surgery in asymptomatic PHPT patients revolve around raised serum calcium levels, renal dysfunction or nephrolithiasis, and bone health. It does not take into account the serum phosphate levels. Depending on the serum level, Hypophosphatemia is divided into mild, moderate, and severe categories. In PHPT, several studies have suggested that asymptomatic PHPT patients with moderate hypophosphatemia may warrant surgical intervention. Treatment of hypophosphatemia in PHPT is based upon the degree of hypophosphatemia, and treatment is given according to that oral or intravenous route; after surgical and medical treatment of PHPT, phosphate levels gradually normalized. But even after these considerations, phosphate levels in PHPT are not given much importance.

A rare presentation of scrub typhus: myocarditis, acute liver failure and leukemoid reaction.

Scrub typhus is a mite borne zoonosis, caused by Orientia tsutsugamushi, a gram-negative intracellular organism. This infection usually presents in high prevalence in the rural areas of East Asia and Western pacific islands. It usually presents with fever, chill, myalgia, headache, skin rashes, having pathognomonic and skin lesion i.e. eschar in ~10% cases in Indian subcontinent. It can present with life-threatening complications on occasional. The simultaneous presentation of more than two complications is uncommon, rarely reported in literature. Here we report a case of 37-year-old woman with acute febrile illness, complicated with myocarditis, acute liver failure and leukemoid reaction. She was diagnosed promptly and successfully treated with doxycycline with full recovery of the complications.
