RESUMEN
OBJECTIVES: 46, XY difference/disorder of sex development (DSD) is a relatively uncommon group of heterogeneous disorders with varying degree of underandrogenization of male genitalia. Such patients should be approached systematically to reach an aetiological diagnosis. However, we lack, at present, a clinical practice guideline on diagnostic approach in 46, XY DSD from this part of the globe. Moreover, debate persists regarding the timing and cut-offs of different hormonal tests, performed in these cases. The consensus committee consisting of 34 highly experienced endocrinologists with interest and experience in managing DSD discussed and drafted a consensus statement on the diagnostic approach to 46, XY DSD focussing on relevant history, clinical examination, biochemical evaluation, imaging and genetic analysis. CONTENT: The consensus was guided by systematic reviews of existing literature followed by discussion. An initial draft was prepared and distributed among the members. The members provided their scientific inputs, and all the relevant suggestions were incorporated. The final draft was approved by the committee members. SUMMARY: The diagnostic approach in 46, XY DSD should be multidisciplinary although coordinated by an experienced endocrinologist. We recommend formal Karyotyping, even if Y chromosome material has been detected by other methods. Meticulous history taking and thorough head-to-toe examination should initially be performed with focus on external genitalia, including location of gonads. Decision regarding hormonal and other biochemical investigations should be made according to the age and interpreted according to age-appropriate norms Although LC-MS/MS is the preferred mode of steroid hormone measurements, immunoassays, which are widely available and less expensive, are acceptable alternatives. All patients with 46, XY DSD should undergo abdominopelvic ultrasonography by a trained radiologist. MRI of the abdomen and/or laparoscopy may be used to demonstrate the Mullerian structure and/or to localize the gonads. Genetic studies, which include copy number variation (CNV) or molecular testing of a candidate gene or next generation sequencing then should be ordered in a stepwise manner depending on the clinical, biochemical, hormonal, and radiological findings. OUTLOOK: The members of the committee believe that patients with 46, XY DSD need to be approached systematically. The proposed diagnostic algorithm, provided in the consensus statement, is cost effective and when supplemented with appropriate genetic studies, may help to reach an aetiological diagnosis in majority of such cases.

Diabetic kidney disease (DKD) occurs in approximately 20-40% of patients with type 2 diabetes mellitus. Patients with DKD have a higher risk of cardiovascular and all-cause mortality. Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers and antihyperglycemic drugs form the mainstay of DKD management and aim to restrict progression to more severe stages of DKD. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) control hyperglycemia by blocking renal glucose reabsorption in addition to preventing inflammation, thereby improving endothelial function and reducing oxidative stress; consequently, this class of prescription medicines is emerging as an important addition to the therapeutic armamentarium. The EMPA-REG OUTCOME, DECLARE TIMI 58, and CANVAS trials demonstrated the renoprotective effects of SGLT2i, such as restricting decline in glomerular filtration rate, in the progression of albuminuria, and in death due to renal causes. The renoprotection provided by SGLT2i was further confirmed in the CREDENCE study, which showed a 30% reduction in progression of chronic kidney disease, and in the DELIGHT study, which demonstrated a reduction in albuminuria with dapagliflozin compared with placebo (- 21.0%, confidence interval [CI] - 34.1 to - 5.2, p = 0.011). Furthermore, a meta-analysis demonstrated a reduced risk of dialysis, transplantation, or death due to kidney disease (relative risk 0.67; 95% CI 0.52-0.86; p = 0.0019) and a 45% risk reduction in worsening of renal function, end-stage renal disease, or renal death (hazard ratio 0.55, CI 0.48-0.64, p < 0.0001) with SGLT2i, irrespective of baseline estimated glomerular filtration rate. Thus, there is emerging evidence that SGLT2i may be used to curb the mortality and improve the quality of life in patients with DKD. However, clinicians need to effectively select candidates for SGLT2i therapy. In this consensus statement, we have qualitatively synthesized evidence demonstrating the renal effects of SGLT2i and proposed recommendations for optimal use of SGLT2i to effectively manage and delay progression of DKD.
RESUMEN
Tolosa- Hunt syndrome is a rare steroid responsive disorder caused by granulation tissue involving the cavernous sinus or superior orbital fissure presenting as painful ophthalmoplegia and facial pain. In this report, we describe coexistence of Tolosa-Hunt syndrome with ocular myasthenia which may point towards an autoimmune etiological basis behind the cavernous sinus granulation tissue formation and also offered therapeutic challenge to ameliorate the symptoms.

Pulmonary renal syndrome (PRS) is characterized by both diffuse alveolar haemorrhage and glomerulonephritis as pathological features. Several immunologic and non-immunologic mechanisms including anti-neutrophil cytoplasmic antibody (ANCA)-positive vasculitis, anti-glomerular basement membrane disease, and systemic lupus erythematosus are commonly involved in the pathogenesis of the syndrome. We herein present a 60-year-old woman, non-smoker, who presented with fever, polyarthralgia, and the spreading of generalized purpuric rashes. The patient displayed rapid deterioration over the following two weeks marked by progressive declining renal function followed by haemoptysis. The patient was subsequently diagnosed with PRS, which was confirmed by the radiological evidence of alveolar haemorrhage and the histopathological evidence of pauci-immune glomerulonephritis. All immune markers including ANCA were negative. The patient was successfully treated with hemodialysis and immunosuppressive therapy. ANCA-negative vasculitis is a rare entity and even more rare as an etiology of PRS. An early diagnosis of this disease and its timely intervention is crucial.

Hashimoto's encephalopathy (HE) is a steroid-responsive relapsing neuropsychiatric disorder associated with high titers of antithyroid antibody with or without thyroid dysfunction. We report a case of HE in a 78 year old female who developed sudden onset behavioral abnormalities associated with choreiform movement of extremities. All causes of vascular, infective, metabolic, autoimmune, paraneoplastic and toxic encephalopathy were excluded. Anti-thyroid peroxidase (anti-TPO) antibody was found to be raised with very high titre. A diagnosis of HE was made. Prompt treatment with high dose steroid led to dramatic improvement of symptoms including choreiform movement.
RESUMEN
We report a 55-year-old female who presented with trochanteric fracture of right femur. Examination and investigation revealed a huge retrosternal goiter with compression of great vessels which was asymptomatic for more than two decades. Subsequent investigation confirmed it as a case of toxic multinodular goitre with subclinical hyperthyroidism which is the possible cause of secondary osteoporosis and fracture. Unusual presentation makes the case reportable.
