Comparative diagnostic utility of different urinary biomarkers during pre-albuminuric stages of non-hypertensive type 2 diabetic nephropathy.

Background & objectives: Activation of renin-angiotensin system and tubulointerstitial damage might be seen in pre-albuminuria stage of diabetic nephropathy (DN). Here, diagnostic utility of four urinary biomarkers [Angiotensinogen (Angio), Interleukin (IL)-18, Neutrophil Gelatinase-Associated Lipocalin (NGAL) and Cystatin] during pre-albuminuria stages of non-hypertensive type 2 diabetes patients was studied. Methods: A total of 952 type 2 diabetes mellitus (T2DM) patients were screened for nephropathy [estimated glomerular filtration rate (eGFR) ≥120 ml/min and albumin-creatinine ratio (ACR) ≥30], and 120 patients were followed up for one year. At one year, they were classified into hyperfiltration (43), normoalbuminuria (29) and microalbuminuria (48) groups. Another 63 T2DM patients without nephropathy were included as controls. Hypertension, patients on angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, eGFR <60 ml/min/1.73 m2 and all proteinuric conditions were excluded. All were subjected to testing for urine protein, ACR, HbA1C, eGFR, along with urinary biomarkers (IL-18, cystatin-C, NGAL and AGT). Comparative analysis of all the diagnostic tests among different subgroups, correlation and logistic regression was done. Results: Urinary IL-18/Cr, cystatin/creatinine (Cr) and AGT/Cr levels were higher in groups of hyperfiltration (13.47, 12.11 and 8.43 mg/g), normoalbuminuria (9.24, 11.74 and 9.15 mg/g) and microalbuminuria (11.59, 14.48 and 10.24 mg/g) than controls (7.38, 8.39 and 1.26 mg/g), but NGAL/Cr was comparable. The area under receiver operating characteristic curve (AUC) and sensitivity of AGT to detect early CKD were higher than ACR and eGFR (0.91 and 90.4%, 0.6 and 40% and 0.6 and 37%, respectively). AUC values of other biomarkers, namely IL-18/Cr, cystatin/Cr and NGAL/Cr, were 0.65, 0.64 and 0.51, respectively. Angio/Cr and IL-18/Cr showed correlation with log albuminuria (r=0.3, P=0.00, and r=0.28, P=0.00, respectively). NGAL showed correlation with log eGFR (r=0.28 P=0.00). Multivariate logistic analysis showed that odds ratio of developing nephropathy was 7.5 times with higher values of log Angio/Cr. Interpretation & conclusions: Urinary AGT showed a higher diagnostic value than ACR and eGFR followed by IL-18 and cystatin to diagnose DN during pre-albuminuric stages.

PCOS patients differ in meal timings rather than total caloric or macronutrient intake in comparison to weight matched controls.

BACKGROUND: There is paucity of data related to dietary patterns in women with PCOS with heterogenous phenotypes compared to weight matched healthy women. In the present study, we studied the influence of diet and dietary patterns in relation to BMI and phenotype of PCOS women. DESIGN: Case control study in a tertiary care hospital. PATIENTS: 168 PCOS women and 102 age matched healthy women were recruited. All were subjected to clinical examination, biochemical, hormonal and dietary assessment based on 2-day dietary recall and direct interview by dieticians. RESULTS: There was no difference in the total energy and macronutrient distribution among the lean and obese PCOS women compared to weight matched controls. There was a higher junk intake and lower fibre intake among PCOS patients compared to controls. There was no difference in the total energy or macronutrient distribution or meal timings among different phenotypes of PCOS. Around 40% PCOS women had a late/missed breakfast pattern compared to 15% of healthy controls (p-0.00). In multivariable logistic regression analysis, we observed that late breakfast and late lunch patterns were associated with PCOS independent of BMI (OR-3.3[CI- 1.7-6.8] and 3.0 [CI- 1.2-6.9]). Junk intake was correlated with BMI, glucose and cholesterol levels and dairy intake was correlated with hirsuitism score. CONCLUSION: We demonstrate for the first time that PCOS women differ significantly from weight matched controls in the timings of their breakfast and lunch intake rather than the total caloric intake and macronutrient distribution. Whether correction of meal timings and food choices can improve the phenotypic manifestations of PCOS remains to be seen.

Effect of Vitamin D on Urinary Angiotensinogen Level in Early Diabetic Nephropathy.

BACKGROUND: Urinary angiotensinogen (UAGT) is supposed to be a marker of activation of the intrarenal renin- angiotensin system (RAS) system in early diabetic nnephropathy (EDN). Vitamin D has been studied as a negative regulator of the circulating and tissue RAS activity, so its supplementation may prevent the progression of diabetic nephropathy (DN). This study was planned to assess the RAS activation and effect of vitamin D supplementation in EDN progression by estimating the UAGT level. METHODS: A total of 103 EDN subjects were randomized in two groups to receive either cholecalciferol (54) or matching placebo (49) in a double-blind manner. All were subjected to routine investigations, urinary albumin-to-creatinine ratio (UACR), UAGT, vitamin D, and intact parathyroid hormone (iPTH) at the 0 and 6 months. A total 40 healthy controls were also included for assessment of the same investigations at 0 month. RESULTS: Significant reduction of UACR, UAGT, and iPTH level were corroborated with an increase in 25(OH) vitamin D level from 0 to 6 months (all four P < 0.001). After 6 months, the median [interquartile range (IQR)] of UAGT and UACR levels was significantly lower in the cholecalciferol group as compared to placebo group (p < 0.001 and P = 0.04, respectively). The median UAGT level was significantly higher in patients with EDN (cholecalciferol & placebo Group) than control group at 0 month (p = 0.001). CONCLUSION: Significantly higher UAGT levels in EDN supports the role of intrarenal RAS activation. A significant decrease in UAGT level in the cholecalciferol group supports the beneficial role of vitamin D supplementation in the progression of EDN.

Changes in ß-Cell Function in Offspring of Type-2 Diabetic Patients, as per Fasting and Two-Hour Plasma Glucose Levels.

Background The changes in ß-cell function in high-risk populations who are apparently in the normal glucose tolerant stage are still under investigation for designing earlier prevention strategies. This study analyzes changes in ß-cell function and insulin sensitivity across fasting and two-hour glucose categories spanning normal glucose tolerance (NGT) to impaired glucose tolerance (IGT), in offspring of subjects with type-2 diabetes mellitus (T2DM) compared to the controls without a known family history of T2DM. Methods Offspring of T2DM patients (cases) and individuals without a family history of T2DM (controls) were the subjects for this cross-sectional study. All participants underwent a 75 g oral glucose tolerance test and blood samples were collected for plasma glucose, insulin, C-peptide and proinsulin, at zero, 30, 60, and 120 minutes.  Results A total of 358 cases (age 23.0 ± 10.8 years, 54% males) and 287 controls (age 28.4 ± 8.10 years, 65% males) were the subjects of this study. Cases and controls were divided into subgroups based on fasting and two-hour glucose categories spanning NGT to IGT. Compared to the reference category of controls (< 80 mg/dL for fasting glucose and < 84 mg/dL for two-hour glucose), cases with IGT had ~60% decline in both ß-cell compensation (as measured as disposition index {0-120}) and insulin sensitivity (as measured as whole-body insulin sensitivity index {0-120}); adjusted for age, gender, and body mass index. From lower to higher fasting and two-hour glucose categories, there was a continuous and significant decline in ß-cell compensation in both cases and controls. Significant reduction in first-phase insulin secretion, as measured as insulinogenic (0-30) index, was only observed among two-hour glucose categories, not among the fasting glucose categories. In the transition from late NGT cases to IGT cases, there was a significant decline in ß-cell compensation, first-phase insulin secretion (more prominent than a decline in overall ß-cell secretion) and the changes in whole-body insulin sensitivity were not statistically significant. Conclusions The decline in ß-cell compensation was continuous and significant in offspring of subjects with type-2 diabetes and controls without a known family history of diabetes from early normal glucose tolerant ranges to impaired glucose tolerant ranges. Compared to the strictest glucose controlled category of controls, approximately 60% decline was observed in ß-cell compensation and insulin sensitivity, in impaired glucose tolerant offspring of subjects with type-2 diabetes mellitus.

Prevalence of Macroprolactinemia in People Detected to Have Hyperprolactinemia.

Background Macroprolactinemia is an analytic laboma encountered as a part of prolactin assay. No data are available on the burden of macroprolactinemia in Indians. This study aimed to determine the prevalence and predictors of macroprolactinemia among people with hyperprolactinemia. Methods Consecutive patients detected to have serum prolactin > 18 ng/mL as per the upper reference limit were further screened for macroprolactin by post-polyethylene-glycol (PEG)-precipitation test. Macroprolactinemia was defined as post-PEG recovery of prolactin < 40%. Results The four most common underlying etiologies for the testing of hyperprolactinemia were polycystic ovary syndrome ( n = 402; 32.71%), pituitary adenomas ( n = 318; 25.87%), drug-induced hyperprolactinemia ( n = 224; 18.23%), and infertility ( n = 126; 10.25%). A total of 1,229 patients (male:female = 191:1038) having mean age 30.46 ± 10.14 years had hyperprolactinemia, of which 168 (13.7%) were diagnosed to have macroprolactinemia. Macroprolactinemia was significantly higher in females than males (15.03 vs. 6.28%; p < 0.001). Age quartile-based analysis revealed no difference in occurrence of macroprolactinemia. Only 34 patients (2.76%) with macroprolactinemia (< 40% recovery of prolactin post-PEG precipitation) had raised prolactin levels after recovery. These patients primarily had underlying pituitary pathology. Conclusion Macroprolactinemia is not uncommon in people being tested for hyperprolactinemia. We should not hesitate to screen for macroprolactinemia in patients who have incidentally been detected to have hyperprolactinemia.

Secondary diabetes as a rare complication of glycogen storage disease 1a: case report and review of literature.

Glycogen storage diseases (GSDs) are disorders of carbohydrate metabolism and hypoglycemia is their hallmark. Secondary diabetes with glycogen storage disease, which seems rather paradoxical, has been rarely reported. A 13-year-old girl previously diagnosed to have GSD 1a presented to the emergency with multiple episodes of vomiting and loss of consciousness. She had hyperglycemia, ketonuria, hyperlactatemia and metabolic acidosis, suggestive of diabetic ketosis with acidosis possibly contributed by both high serum lactate and serum ketones. Her glycated hemoglobin was high, with detectable serum insulin levels, which suggested secondary diabetes in the background of GSD Ia. Her management posed a therapeutic challenge. She was managed with insulin and achieved good glycemic control. We wish to conclude that GSD may rarely lead to secondary diabetes as a complication and the management is complex owing to the nature of the disease. Insulin remains the mainstay of the treatment.

Carbohydrate-rich Meals Have no Impact on Post-prandial Lipid Parameters in Indians with Subclinical and Overt Primary Hypothyroidism.

BACKGROUND AND AIMS: The impact of altered cholesterol metabolism on post-prandial lipids in Indians with hypothyroidism is not known. This study evaluated the impact of overt primary hypothyroidism (OPH) and subclinical hypothyroidism (ScH) on post-prandial lipids after a standardised, carbohydrate-rich, mixed meal. METHODS: Endocrinology outpatients were screened for possible inclusion into the study. Patients >18 years of age with hypothyroidism who were not taking levothyroxine and who did not present with any comorbidities underwent biochemical evaluation following a carbohydrate-rich, mixed meal. Assessments included total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), triglycerides, lipoprotein-A (Lp-A), apolipoprotein-A1 (apo-A1), apolipoprotein-B (apo-B), insulin and fasting glucose. Assessments were carried out 1 hour, 2 hours and 4 hours after the meal. Patients were compared against healthy matched controls recruited from healthcare professionals in the hospital (asymptomatic and apparently healthy nursing staff, reception staff and ward staff). RESULTS: Data from 194 patients (161 with ScH and 33 with OPH) and 40 euthyroid controls were analysed. Anthropometry, body mass index, glycaemia and insulin resistance were comparable among patients with OPH and ScH, and controls. LDL-C and Lp-A were significantly higher in those with OPH, compared with ScH and controls, at baseline, 1 hour, 2 hours and 4 hours after mixed meal consumption (all p<0.05). There was progressive and similar decline in post-prandial TC, LDL-C and Lp-A in all three groups. Triglycerides were similar among the OPH, ScH and control groups, both in fasting and post-prandial state, with a progressive and similar increase in post-prandial triglycerides in all three groups. CONCLUSION: This study demonstrated that severity of hypothyroidism had no impact on post-prandial TC, LDL-C and Lp-A. In addition, hypothyroidism had no impact on post-prandial triglycerides. Therefore, we conclude that lipid profile can be reliably estimated in a non-fasting state in individuals with ScH and OPH.

Bilateral Adrenocortical Carcinoma Presenting as Acute Adrenal Insufficiency.

The presentation of adrenocortical carcinoma (ACC) with bilateral adrenal masses and acute adrenal insufficiency is exceedingly rare and has only been seen in anecdotal case reports. Herein, we describe the case of a 50-year-old male who presented with a painful abdominal lump, loss of weight and appetite, several episodes of vomiting, and hypotension. Imaging studies were suggestive of bilateral adrenal masses and a lung mass. Hormonal work-up was suggestive of acute adrenal insufficiency, with the adrenal masses being non-secretory. An ultrasound-guided biopsy from one of the adrenal masses was suggestive of ACC, thus confirming the diagnosis as bilateral ACC with distant metastases. Bilateral adrenalectomy was planned for the patient, but unfortunately, he succumbed to his disease before the surgery.

Cushing's syndrome due to primary pigmented nodular adrenal disease in two brothers with Carney complex.

Two brothers (19 and 18 years old, respectively) presented with weight gain and stunted growth since the age of 10 years. They had spotty skin pigmentation over the face along with florid features of Cushing's syndrome with low bone density, renal calculi, dyslipidaemia, hypertension, and dilated cardiomyopathy. They underwent evaluation of the hypothalamic-pituitary-adrenals axis, which suggested ACTH-independent Cushing's syndrome, and the abdominal CT imaging revealed normal adrenals. The diagnosis of Familial Cushing's syndrome with primary pigmented nodular adrenal disease and Carney complex was made. Bilateral adrenalectomy was carried out in both of them with resolution of the features of hypercortisolaemia post-operatively.

Catamenial Acute Intermittent Porphyria Managed with GnRH Analogues and Estrogen and Progesterone Add-back Therapy.

BACKGROUND: Catamenial precipitation of attacks of acute intermittent porphyria (AIP) is commonly treated with gonadotropin-releasing hormone analogues (GnRHas). However, this leads to various adverse effects that might necessitate "add-back" therapy with estrogen. The literature on the efficacy and safety of such therapy is scarce. CASE: A 15-year-old girl presented to us with recurrent catamenial attacks of AIP. GnRHa therapy led to near-complete amelioration of the episodes but her bone density worsened as an adverse effect. To circumvent this, low-dose estrogen was added to her regimen as an "add-back" therapy, which was later coupled with cyclical progesterone. She continues to do well using this regimen, with no new episodes. SUMMARY AND CONCLUSION: GnRHa therapy with estrogen "add-back" is an attractive option for treating catamenial AIP episodes.

The correlation between erectile dysfunction and metabolic syndrome in an Indian population: A cross-sectional observational study.

Objective: To evaluate the relationship between erectile dysfunction (ED), based on the five-item International Index of Erectile Function questionnaire (IIEF-5), and presence of metabolic syndrome (MetS) or its components based on Adult Treatment Panel III guidelines. We also explored the impact of increasing insulin resistance (IR), as calculated using the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) equation, on severity of ED. Pathophysiological links between ED and testosterone were re-evaluated. Patients and methods: In all, 357 patients with ED were evaluated; 53 patients with primary, psychogenic, surgical, post-traumatic or drug-induced ED were excluded. The remaining 304 patients were evaluated after obtaining written informed consent. The Institutional Review Board approved the study. We assessed comorbidities, IIEF-5 scores, lower urinary tract symptoms (LUTS) based on International Prostate Symptom Score (IPSS), blood sugars, lipid and hormonal profiles, and vitamin D3 levels. Further evaluation was done when indicated. Results: In all, 171 patients had MetS and 134 had pre-existing comorbidities (diabetes mellitus, 58; hypertension, 73; coronary artery disease, 13). The mean (SD) age was 44.6 (9.21) years and IIEF-5 score was 13.81 (3.17). ED severity was significantly correlated with presence of MetS. On multivariate analysis, there were significant correlations between ED and waist circumference, serum triglycerides, and fasting blood sugar. There was a statistically significant positive correlation between serum testosterone and IIEF-5 score (r = +0.292). The mean (SD) IR value (using the HOMA-IR formula) was 2.64 (2.87), which was statistically and negatively correlated with IIEF-5 scores (r = - 0.398). Receiver operating characteristic analysis showed that an IIEF-5 score of <14 predicted MetS and a HOMA-IR value of >2.1778 predicted MetS. Conclusion: MetS or its components were present in 56.25% of the patients. Therefore presence of ED merits further evaluation for presence of MetS. This may help to prevent catastrophic and life-threatening consequences of MetS.

Predictors of Metabolic Syndrome among Polycystic Ovary Syndrome Sisters.

AIMS: Metabolic syndrome among PCOS sisters may vary depending on the phenotype. The aim of the present study was to analyze the prevalence of metabolic syndrome among different phenotypes of PCOS sisters. DESIGN: Case control study. MATERIALS AND METHODS: Two hundred sisters of PCOS patients and 99 age matched healthy controls underwent history, clinical examination, biochemical parameters for metabolic syndrome and hormonal assessment. RESULTS: Of 200 sisters, 85 were unaffected (UA group), 21 sisters had hyperandrogenemia (HA group), and 94 sisters had irregular periods or hyperandrogenemia. We observed that the frequency of metabolic syndrome among PCOS sisters was comparable to age and weight matched controls (30% vs 27%). The prevalence of metabolic syndrome was higher in HA and AFFECTED sisters (around 30% in both) compared to UA sisters (20%). The presence of metabolic syndrome was significantly associated with age, BMI, HOMA-IR and free testosterone. After correction for age and BMI, metabolic syndrome was significantly associated with HOMA-IR (P - 0.05) and free testosterone (P - 0.03). CONCLUSION: Based on above findings, we conclude that affected sisters and those with higher age, BMI and hyperandrogenemia have a high risk of metabolic syndrome compared to unaffected sisters.

Presence, patterns & predictors of hypocortisolism in patients with HIV infection in India.

BACKGROUND & OBJECTIVES: : Adrenal insufficiency (AI) is rarely diagnosed in patients with HIV infection, in spite of autopsy studies showing very high rates of adrenal involvement. This study was aimed to determine the presence, patterns and predictors of AI in patients with HIV infection. METHODS: : Consecutive HIV patients, 18-70 yr age, without any severe co-morbid state, having at least one-year follow up at the antiretroviral therapy clinic, underwent clinical assessment and hormone assays. RESULTS: : From initially screened 527 patients, 359 patients having good immune function were analyzed. Basal morning cortisol <6 µg/dl (<165 nmol/l; Group 1), 6-11 µg/dl (165-300 nmol/l; Group 2), 11-18 µg/dl (300-500 nmol/l; Group 3) and ≥18 µg/dl (500 nmol/l; Group 4) were observed in 13, 71, 199 and 76 patients, respectively. Adrenocorticotropic hormone (ACTH) stimulation test revealed 87 patients (24.23%) to have AI. AI in groups 1-4 was 100, 56.34, 17.09 and 0 per cent, respectively. AI patients were more likely to be females (P< 0.05), having longer disease duration (P< 0.05), immune reconstitution inflammatory syndrome, hyperkalaemia (P< 0.01), lower fasting glucose (P< 0.01), dehydroepiandrosterone sulphate (DHEAS) and vitamin D. Regression analysis revealed morning cortisol and DHEAS to be best predictors of AI (P=0.004 and 0.028, respectively). INTERPRETATION & CONCLUSIONS: : AI is a significant problem in HIV-infected individuals, observed in nearly a quarter of patients. Diagnosis warrants high index of suspicion and low threshold for screening, especially in those having low DHEAS and hyperkalaemia. Morning cortisol is a reasonable screening test, with ACTH stimulation warranted to confirm diagnosis, especially in patients with morning cortisol <11 µg/dl (300 nmol/l).

Phenotypic presentation of adolescents with overt primary hypothyroidism.

BACKGROUND: The phenotypic presentation of overt hypothyroidism during adolescence is less well characterized. The aim of the study was to study the phenotypic presentation of patients with overt hypothyroidism presenting during adolescence (age 9-18 years). METHODS: Records of adolescent patients with overt hypothyroidism (thyroid stimulating hormone [TSH]>10 mIU/L) were retrospectively analyzed for presenting complaints, height and pubertal status. RESULTS: A total of 67 patients (40 females and 37 males, average age 13.2+2.3 years) with a mean TSH of 241.3±336.6 mIU/L were included. The commonest presentation was short stature in 46.2% of patients followed by neck swelling (16.4%) and weight gain (11.9%). The mean height standard deviation score (SDS) was -2.5+2.11, 43% of patients had less than 3 SDS. The height age and bone age were around 3 years less than the chronological age. The bone age significantly correlated with the height age but not with TSH levels. Three patients referred from neurology with primary complaints of headache had pituitary hyperplasia and one presented with hypokalemic periodic paralysis. Seven had delayed puberty and one patient had early periods due to huge ovarian cysts. CONCLUSIONS: In the present study, severe short stature and uncommon phenotypic presentations were a consequence of long-standing severe untreated hypothyroidism.

Occurrence, patterns & predictors of hypogonadism in patients with HIV infection in India.

BACKGROUND & OBJECTIVES: Data on hypogonadism among human immunodeficiency virus (HIV)-infected Indians are not available. This study was aimed to evaluate the occurrence, pattern and predictors of hypogonadism in HIV-infected Indians. METHODS: Consecutive stable HIV-infected patients, 18-70 yr age, without any severe comorbid state, having at least one year follow up data at the antiretroviral therapy clinic, underwent clinical assessment and hormone assays. RESULTS: From initially screened 527 patients, 359 patients (225 males; 134 females), having disease duration of 61.44±39.42 months, 88.58 per cent on highly active antiretroviral therapy (HAART), 40.67 per cent having tuberculosis history and 89.69 per cent with vitamin D insufficiency were analyzed. Testosterone <300 ng/dl was documented in 39.11 per cent males. Primary, hypogonadotropic hypogonadism (HypoH) and compensated hypogonadism were observed in 7.56, 31.56 and 12.44 per cent males, respectively. Males with hypogonadism were significantly older (P=0.009), and had higher opportunistic infections (P<0.001) with longer disease duration (P=0.05). Menstrual abnormalities were observed in 40.3 per cent females, who were significantly older (P<0.001), had lower CD4 count (P=0.038) and higher tuberculosis history (P=0.005). Nearly 46.3, 16.2 and 13 per cent women with menstrual abnormalities were in peri-/post-menopausal state, premature ovarian insufficiency (POI) and HypoH, respectively. Age, CD4 count at diagnosis and 25(OH)D were best predictors of male hypogonadism. Age and CD4 count increment in first 6-12 months following HAART were the best predictors of POI. INTERPRETATION & CONCLUSIONS: Hypogonadism was observed to be a significant problem in HIV-infected men and women in India, affecting 39 and 29 per cent patients, respectively. HypoH was the most common form in males whereas ovarian failure being the most common cause in females.

Menstrual Cycle Abnormalities in Patients with Prolactinoma and Drug-induced Hyperprolactinemia.

BACKGROUND AND OBJECTIVE: Hyperprolactinemia affects the reproductive endocrine axis; however, the degree of dysfunction may vary depending on etiology. The aim of the present study was to analyze menstrual cyclicity in patients with prolactinoma and drug-induced hyperprolactinemia (DIH). METHODOLOGY: Patients with prolactinoma and DIH were retrospectively analyzed for menstrual cyclicity at presentation and response to therapy. RESULTS: Of 128 females with hyperprolactinemia, 58 had prolactinoma (41 microadenoma and 17 macroadenoma) and 39 had DIH. Patients with prolactinoma had higher prolactin levels and increased frequency of oligomenorrhea (77.5% vs. 46%) as compared to DIH. Patients with macroprolactinoma had more severe menstrual disturbances compared to microprolactinoma. A higher percentage of patients with microprolactinoma and DIH achieved regular menstrual cycles compared to macroprolactinoma postcabergoline treatment (85% and 90% vs. 65%). There was no correlation between time to regularization of menstrual cycles with age, menstrual cycle length, duration of menstrual irregularity, or initial prolactin level in patients with prolactinoma. Linear regression analysis showed a significant association between time to regularization of menstrual cycles with time to normalization of prolactin levels (P = 0.001). CONCLUSION: There is a prompt restoration of menstrual cycles in patients with microprolactinoma and DIH. Patients with macroprolactinoma have more severe menstrual disturbances and lesser frequency of cycle restoration postcabergoline treatment compared to microprolactinoma and DIH.

Simultaneous Occurrence of Thyroiditis in Ectopic and Eutopic Thyroid Masquerading as Thyroglossal Cyst.

Ectopic thyroid gland is a rare condition usually presenting with neck swelling or hypothyroidism. In most cases, ectopic thyroid tissue is the only functioning thyroid tissue, but it may rarely be associated with normal thyroid gland. Thyroiditis in an ectopic thyroid gland is very rare. Here, we describe a 13-year-old girl who was initially suspected, as a having a thyroglossal cyst. Thyroid functions were suggestive of thyrotoxicosis. She was diagnosed to have simultaneous occurrence of thyroiditis in the ectopic and eutopic thyroid glands. This case was exceedingly rare since this patient presented with thyrotoxicosis unlike previous reported cases who were either euthyroid or hypothyroid.

Adolescent gynecomastia is associated with a high incidence of obesity, dysglycemia, and family background of diabetes mellitus.

BACKGROUND: Gynecomastia during adolescence is common though etiology is not clear. We studied the clinical and hormonal profile of adolescent patients with gynecomastia. METHODOLOGY: Patients who had onset of breast development between age 10 and 20 years were included in this study. Their clinical profile, biochemical, and hormonal parameters were studied. RESULTS: Of 94 patients with gynecomastia, 4 had hypogonadotropic hypogonadism, 4 had hypergonadotropic hypogonadism, and 1 had fibroadenosis, but in majority (90.4%), no apparent cause for breast enlargement was evident. In the idiopathic group, majority were obese (63%). Fourteen (16%) patients had impaired fasting glucose or impaired glucose tolerance. Another twenty patients had subtle abnormalities (high 1 h glucose or glucose peak at 2 h). Twenty-nine percent of lean and 38% of obese patients had mild abnormalities in glucose profile. Sixty percent of patients had family background of diabetes. Obese patients had lower testosterone as compared to lean patients; however, estradiol, luteinizing hormone, and follicle-stimulating hormone levels were similar in the two groups. CONCLUSION: Gynecomastia during adolescence is associated with obesity, dysglycemia, and family background of diabetes mellitus.
