ACTA ENDOCRINOLOGICA (BUC)

Context. Besides its typical features, hypothyroidism comes to notice sometimes with neurologic features like reversible cerebellar ataxia, dementia, peripheral neuropathy, coma, etc. Therefore hypothyroidism should be suspected in all cases of cerebellar ataxia, as it is easily treatable. Objective. Here we illustrate a case of hypothyroidism initially reported with cerebellar ataxia. Case report. A 40 year-old male presented with history of gait-ataxia. His investigations revealed frank primary hypothyroidism with positive anti-TPO antibody. The patient was put on thyroxine and he improved completely within eight weeks. Conclusions. This case report emphasizes that hypothyroidism can present with ataxia as one of the initial features. Therefore, hypothyroidism should be considered in all cases of cerebellar ataxia as it is a reversible cause of ataxia

Background. Erectile dysfunction(ED) in men is a frequent under-reported complication of diabetes mellitus, which is becoming significant health problem worldwide. Aims. The study aims to determine the prevalence and risk factors for development of ED in North Indian patients with type 2 diabetes mellitus. Methods. We used international index of erectile function (IIEF-5) for the assessment of ED in 796 patients with type 2 diabetes mellitus. We recorded the age, duration of diabetes, glycemic status, body mass index, diabetes medications, microvascular and macrovascular complications. Results. The mean age of patients in the study was 49.38 ± 9.52 years. The prevalence of ED in patients with type 2 diabetes mellitus was 79.4%. Logistic regression analysis revealed that age, body mass index, glycemic control, insulin therapy, retinopathy and nephropathy was not significantly associated with erectile dysfunction in patients with type 2 diabetes mellitus. Duration of diabetes (OR = 1.054, 95% CI 1.007 to 1.102, P=0.023) and vibration perception threshold (OR = 1.071, 95% CI 1.042 to 1.102, P=0.000) were identified as key risk factors for development of ED. Conclusion. Duration of diabetes and peripheral neuropathy emerged as significant risk factors for development of severe erectile dysfunction.

Zygomycosis is a frequently fatal infection in the immunocompromised and diabetic host. A 12 year old girl with type 1 diabetes presented in diabetic ketoacidosis and consolidation of right lung along with thymic abscess causing persistent respiratory symptoms. A diagnosis of\r\nmucormycosis was made on smear examination of the thymic aspirate. Intravenous amphotericin along with surgical excision of the abscess resulted in clinical cure. Thymic involvement as seen in this case is an extremely rare occurrence in a diabetic patient which has not been\r\nreported in literature so far .

Context. Adrenocortical carcinoma (ACC) is a rare neoplasm with an aggressive course and poor prognosis. The worldwide incidence is about 0.5 to 2 cases per million population per year. Oncocytic adrenocortical carcinoma is a rare histopathological variant of ACC with only a few reported cases in the literature. Case report. We report a case of an oncocytic variant of adrenocortical carcinoma in a 21-year-old male patient who presented with a left adrenal mass. Imaging studies confirmed a large left adrenal mass with involvement of the left renal vein and inferior vena cava. Endocrine workup showed mildly elevated serum cortisol levels. Discussion. Oncocytic AAC is a rare histopathological variant of ACC, as well as a rare subgroup of oncocytic adrenal neoplasms Hormonally active or functioning adrenocortical carcinomas most commonly secrete cortisol whereas co-secretion of multiple steroid hormones is a rare phenomenon. Conclusions. Surgery remains the mainstay of treatment, but most of the patients present late with large masses and eventually become unsuitable for curative resection.

Context and objective. Somatostatin analogues and cinacalcet have been suggested to have some role in managing hypophosphatemia. This report highlights challenges in managing surgically incurable tumor induced osteomalacia (TIO) with somatostatin analogues and cinacalcet. Patient and methods. A twenty-two year old patient with severe osteomalacia was diagnosed to have TIO due to left hemipelvis tumor (June 2013). Partial surgical removal of tumor (due to its proximity to neurovascular bundles), led to transient remission for 6 weeks. Clinical worsening in spite of maximum tolerable phosphate and calcitriol dose led to trial of octreotide. Acute improvement in phosphate following subcutaneous octreotide 100 mcg was the basis for use of long acting depot octreotide, which was associated with maximal improvement for 4 months, followed by reduced efficacy. Repeated MRI revealed an increase in residual tumor size. Reevaluation revealed very a high parathyroid hormone. Cinacalcet titrated to 90 mg/day induced hypoparathyroidism, improved hypophosphatemia but caused symptomatic hypocalcemia. Cinacalcet at lower doses (30mg/day), though well tolerated, was less effective in improving hypophosphatemia. There was a near 10-fold reduction (2406 to 246RU/ml) in C-terminal FGF-23 levels with cinacalcet. Reduction in phosphate and calcitriol requirements with cinacalcet may contribute to decreased FGF-23. There was no decrease in tumor size. Conclusion. Octreotide and cinacalcet are effective in controlling hypophosphatemia over short periods. Progressive nature of TIO leading to an increased disease severity, tachyphylaxis may explain decreased efficacy of octreotide, higher cinacalcet requirement, poor tolerability, thus limiting their role in long-term management of TIO.
