Background: It is unclear whether targeted monitoring of acute adrenal insufficiency (AI) related adverse events (AE) such as sick day episodes (SDEs) and hospitalization rate in congenital adrenal hyperplasia (CAH) is associated with a change in the occurrence of these events., Aim: Study temporal trends of AI related AE in the I-CAH Registry., Methods: In 2022, data on the occurrence of AI-related AE in children aged <18 years with 21-hydroxylase deficiency CAH were compared to data collected in 2019., Results: In 2022, a total of 513 children from 38 centers in 21 countries with a median of 8 children (range 1-58) per center had 2470 visits evaluated over a 3-year period (2019-2022). The median SDE per patient year in 2022 was 0 (0-2.5) compared to 0.3 (0-6) in 2019 ( P = .01). Despite adjustment for age, CAH phenotype and duration of study period, a difference in SDE rate was still apparent between the 2 cohorts. Of the 38 centers in the 2022 cohort, 21 had also participated in 2019 and a reduction in SDE rate was noted in 13 (62%), an increase was noted in 3 (14%), and in 5 (24%) the rate remained the same. Of the 474 SDEs reported in the 2022 cohort, 103 (22%) led to hospitalization compared to 299 of 1099 SDEs (27%) in the 2019 cohort ( P = .02)., Conclusion: The I-CAH Registry can be used for targeted monitoring of important clinical benchmarks in CAH. However, changes in reported benchmarks need careful interpretation and longer-term monitoring., (© The Author(s) 2024. Published by Oxford University Press on behalf of the Endocrine Society.)

Objectives: To determine trends in clinical practice for individuals with DSD requiring gonadectomy., Design: Retrospective cohort study., Methods: Information regarding age at gonadectomy according to diagnosis; reported sex; time of presentation to specialist centre; and location of centre from cases reported to the International DSD Registry and who were over 16 years old in January 2019., Results: Data regarding gonadectomy were available in 668 (88%) individuals from 44 centres. Of these, 248 (37%) (median age (range) 24 (17, 75) years) were male and 420 (63%) (median age (range) 26 (16, 86) years) were female. Gonadectomy was reported from 36 centres in 351/668 cases (53%). Females were more likely to undergo gonadectomy (n = 311, P < 0.0001). The indication for gonadectomy was reported in 268 (76%). The most common indication was mitigation of tumour risk in 172 (64%). Variations in the practice of gonadectomy were observed; of the 351 cases from 36 centres, 17 (5%) at 9 centres had undergone gonadectomy before their first presentation to the specialist centre. Median age at gonadectomy of cases from high-income countries and low-/middle-income countries (LMIC) was 13.0 years (0.1, 68) years and 16.5 years (1, 28), respectively (P < 0.0001) with the likelihood of long-term retention of gonads being higher in LMIC countries., Conclusions: The likelihood of gonadectomy depends on the underlying diagnosis, sex of rearing and the geographical setting. Clinical benchmarks, which can be studied across all forms of DSD will allow a better understanding of the variation in the practice of gonadectomy.

Objective: Despite published guidelines no unified approach to hormone replacement in congenital adrenal hyperplasia (CAH) exists. We aimed to explore geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids in CAH., Design: This retrospective multi-center study, including 31 centers (16 countries), analyzed data from the International-CAH Registry., Methods: Data were collected from 461 patients aged 0-18 years with classic 21-hydroxylase deficiency (54.9% females) under follow-up between 1982 and 2018. Type, dose and timing of glucocorticoid and mineralocorticoid replacement were analyzed from 4174 patient visits., Results: The most frequently used glucocorticoid was hydrocortisone (87.6%). Overall, there were significant differences between age groups with regards to daily hydrocortisone-equivalent dose for body surface, with the lowest dose (median with interquartile range) of 12.0 (10.0-14.5) mg/m2/day at age 1-8 years and the highest dose of 14.0 (11.6-17.4) mg/m2/day at age 12-18 years. Glucocorticoid doses decreased after 2010 in patients 0-8 years (P < 0.001) and remained unchanged in patients aged 8-18 years. Fludrocortisone was used in 92% of patients, with relative doses decreasing with age. A wide variation was observed among countries with regards to all aspects of steroid hormone replacement., Conclusions: Data from the I-CAH Registry suggests international variations in hormone replacement therapy, with a tendency to treatment with high doses in children.

Background: Although congenital adrenal hyperplasia (CAH) is known to be associated with adrenal crises (AC), its association with patient- or clinician-reported sick day episodes (SDE) is less clear., Methods: Data on children with classic 21-hydroxylase deficiency CAH from 34 centers in 18 countries, of which 7 were Low or Middle Income Countries (LMIC) and 11 were High Income (HIC), were collected from the International CAH Registry and analyzed to examine the clinical factors associated with SDE and AC., Results: A total of 518 children-with a median of 11 children (range 1, 53) per center-had 5388 visits evaluated over a total of 2300 patient-years. The median number of AC and SDE per patient-year per center was 0 (0, 3) and 0.4 (0.0, 13.3), respectively. Of the 1544 SDE, an AC was reported in 62 (4%), with no fatalities. Infectious illness was the most frequent precipitating event, reported in 1105 (72%) and 29 (47%) of SDE and AC, respectively. On comparing cases from LMIC and HIC, the median SDE per patient-year was 0.75 (0, 13.3) vs 0.11 (0, 12.0) (P < 0.001), respectively, and the median AC per patient-year was 0 (0, 2.2) vs 0 (0, 3.0) (P = 0.43), respectively., Conclusions: The real-world data that are collected within the I-CAH Registry show wide variability in the reported occurrence of adrenal insufficiency-related adverse events. As these data become increasingly used as a clinical benchmark in CAH care, there is a need for further research to improve and standardize the definition of SDE., (© The Author(s) 2020.

Context: Larger studies on outcomes in males with 45,X/46,XY mosaicism are rare., Objective: To compare health outcomes in males with 45,X/46,XY diagnosed as a result of either genital abnormalities at birth or nongenital reasons later in life., Design: A retrospective, multicenter study., Setting: Sixteen tertiary centers., Patients or Other Participants: Sixty-three males older than 13 years with 45,X/46,XY mosaicism., Main Outcome Measures: Health outcomes, such as genital phenotype, gonadal function, growth, comorbidities, fertility, and gonadal histology, including risk of neoplasia., Results: Thirty-five patients were in the genital group and 28 in the nongenital. Eighty percent of all patients experienced spontaneous pubertal onset, significantly more in the nongenital group (P = 0.023). Patients were significantly shorter in the genital group with median adult heights of 156.7 cm and 164.5 cm, respectively (P = 0.016). Twenty-seven percent of patients received recombinant human GH. Forty-four patients had gonadal histology evaluated. Germ cells were detected in 42%. Neoplasia in situ was found in five patients. Twenty-five percent had focal spermatogenesis, and another 25.0% had arrested spermatogenesis. Fourteen out of 17 (82%) with semen analyses were azoospermic; three had motile sperm., Conclusion: Patients diagnosed as a result of genital abnormalities have poorer health outcomes than those diagnosed as a result of nongenital reasons. Most patients, however, have relatively good endocrine gonadal function, but most are also short statured. Patients have a risk of gonadal neoplasia, and most are azoospermic, but almost one-half of patients has germ cells present histologically and up to one-quarter has focal spermatogenesis, providing hope for fertility treatment options., (Copyright © 2019 Endocrine Society.)

Primary squamous cell carcinoma of the thyroid is a very rare thyroid malignancy (less than 1% of thyroid cancers) with unfavorable clinical evolution and median survival less than one year, due to highly local tumor invasiveness with airway obstruction, metastases and treatment complications. We present a 62-year-old female patient with a fixed, rapidly increasing 5 cm right thyroid nodule, generating compressive signs and significant weight loss, resembling anaplastic thyroid carcinoma. Thyroid hormones, antithyroid antibodies and calcitonin were normal. Computed tomography (CT) scan revealed mediastinal extension of the tumor and excluded the presence of lymph nodes or other tumors (T3N0M0). Total thyroidectomy was performed and histopathological evaluation revealed squamous cell carcinoma, which was confirmed by immunohistochemistry, showing diffuse positivity for CK7, CK19, CK34βE12, galectin-3, EGFR, focal positivity for p63 and negativity for TTF-1 and CD5. Subsequently, the patient underwent chemotherapy (Paclitaxel, Cisplatin, Epirubicin) and radiotherapy (40 Gy), but tumor recurrence was noticed one month after surgical resection and continued to grow despite treatment. Nodal and metastases status remained negative at regular follow-up. The patient died within one year after diagnosis. External radiotherapy and chemotherapy were not efficient in our case. New treatment options are needed to improve outcome in primary squamous cell carcinoma of the thyroid.

Sarcomas represent less than 1% of malignant laryngeal tumors and giant cell malignant fibrous histiocytoma is exceptionally rare. Diagnosis is histologically based and immunohistochemistry allows differentiation from other fibro-histiocytic neoplasms. We present the case of a 53-year-old male patient with positive medical history for trichinellosis and tuberculosis, and a laryngeal tumor invading the thyroid and causing respiratory distress by airway obstruction. Total laryngectomy and thyroidectomy were performed followed by thyroxine replacement therapy and radiotherapy. Histologically, the tumor consisted of spindle shaped cells with prominent mitoses, and abundant, osteoclast-like, multinucleated giant cells. Similar lesions were identified in the thyroid, adipose and muscular tissues. Parasitic elements were present in muscles. Tumoral cells showed positive immunostaining for Ki67 (40-50%) and vimentin and negative for AE1/AE3, CD31, S100 and myoglobin; the giant multinucleated cells were CD68-positive. Chronic infection might have had a pathogenic significance.

Autoimmune thyroid diseases (Hashimoto thyroiditis, Graves' disease, postpartum thyroiditis, atrophic thyroiditis and drug induced thyroiditis) are prevalent disorders worldwide, especially in women (related to the millieu of sex steroids and X chromosome effects on the thyroid and the immune system). Disruption of thyroid self tolerance, usually induced by an infection, generates abnormal thyroid--immune interactions, implicating an array of cytokines and their receptors. Thyrocytes achieve antigen presenting cell properties which stimulate effector immune cells (Th1, Th2, Th17), in the context of defective immunomodulatory T regulatory cells, resulting in thyroid lymphocytic infiltration and activation of B cells, with production of antibodies against thyroid antigens, thyroid destruction or stimulation, depending on the Th1-Th2 balance. During pregnancy there is a Th2 predominance sustained by the increased glucocorticoid, estrogen and progesteron levels, which allows tolerance versus the histoincompatible fetoplacental unit. In the postpartum period, the return shift Th2 to Th1 favors the occurrence of postpartum thyroiditis. Altered thyroid hormone levels can influence the immune system, and, on the other side, some immune cells secrete TSH, which exerts endocrine and paracrine, cytokine-like effects. Understanding the complex pathogenesis of autoimmune thyroid disorders is crucial for prevention and management.

The Holt-Oram syndrome or atriodigital dysplasia is an autosomal dominant disorder with near complete penetrance and variable expression, caused by mutations of the TBX5 gene (12q24.1), affecting one in 100 000 live births. 60% of cases are familial and 40% sporadic. We present the case of a 24 years old male patient with a personal history of bilateral coxa vara surgically corrected on the right at the age of 8 years, complicated by osteochondritis, short stature (160 cm), underweight (37 kg, BMI 14.45 kg/cm(2)), triangular face, micrognathia, down slanting palpebral fissures, hypertelorism, low set ears, scoliosis, narrow shoulders, shortened left arm, left thumb agenesia, limited supination, abnormal toes, hypoplastic muscles, atrial septal defect ostium secundum type, incomplete right bundle branch block, hypoacusia and normal intelligence.

Turner syndrome (TS) is characterized by an increased prevalence of hypothyroidism, the main etiology being autoimmunity. The aim of our study was to assess the prevalence of hypothyroidism in patients with Turner syndrome, to analyze the correlations with clinical, chromosomal, hormonal and metabolic features and to compare hypothyroid with euthyroid Turner subjects. We studied 28 patients with TS (mean age 24.68 +/- 9.59yr). 78.57% with 45,XO. 10.71% with 45,XO/46,XX and 10.71% with other karyotypes. Hypothyroidism was diagnosed in 10 patients (35.7%). TSH level was positively correlated with thyroid autoantibodies titer (p < 0.001), maternal age at conception (p< 0.01), the presence of spontaneous puberty (p < 0.05) and relative height (p < 0.05), and negatively correlated with FSH level (p < 0.001) which is an indicator of the estrogenic status, and was not correlated to karyotype. Hypothyroid Turner subjects had higher relative heights (p < 0.05) and lower FSH levels (p < 0.05) than euthyroid subjects, but cholesterol levels and BMI were not significantly different.

Noninsulindependent diabetes mellitus is 2-4 times more prevalent in Turner subjects as compared to normal females, and tends to develop at a younger age, but it is usually mild and responsive to weight loss or monotherapy. The primary pathogenic event is beta cell dysfunction, but insulin resistance also plays a central role and is worsened by the presence of hypertension, obesity and dyslipidemia which are common in Turner syndrome. We present the case of a 30 year-old female patient with short stature, 141cm (<-- 2.5 SD), overweight 51kg, waist circumference 79cm, triangular facies, downslanting palpebral fissures, low set ears, short neck, secondary amenorrhea, palpitations, a history of polyuria, polydypsia of three months duration and a fasting morning glucose of 260 mg/dL. Cardiac and renal defects were excluded, hormonologic evaluation was consistent with hypergonadotropic hypogonadism (FSH 65 mUI/mL) and primary hypothyroidism (TSH 5.68 microUI/mL) and karyotype was 45,XO. She also had hypercholesterolemia (247 mg/dL), hypocalcemia (8 mg/dL), mild elevation of hepatic enzymes (ALAT 51 U/L) and osteopenia (Tscore--2.22). Glycaemic control was achieved with diet only; therapy consisted of hormone replacement theraphy, thyroxine and beta blockers.

Both hypergonadotropic hypogonadism and myasthenia gravis can be parts of type II autoimmune polyendocrine syndrome and association between the two disorders has been reported in few cases. A 14 year old male patient with a personal history of bilateral cryptorchidism and ptosis was referred for delayed puberty. Clinical examination revealed eunuchoid habitus, small, soft testes, gynecomastia, ptosis, a myasthenic deficit score of 22.5 points and an IQ of 84 points. Decreased testosterone (0.064 ng/mL) and elevated LH (64.5 mUI/mL) were consistent with hypergonadotropic hypogonadism and karyotype was normal: 46,XY. Thyroid function, haematologic evaluation, BUN, electrolytes, and glycemia were in the normal range. Therapy consisted of anticholinesterase inhibitors, immunosuppressants, corticotherapy, testosterone; thoracoscopic thymectomy was performed showing thymic lymphoid hyperplasia on histopathologic examination. Myasthenic score improved (12.5 points), progressive virilization occurred, and a year later the patient presented with cushingoid features and obesity.

Ellis-van Creveld syndrome is a rare autosomal recessive disorder caused by mutations in the EVC and EVC2 gene (4p16), characterized by chondrodystrophy, postaxial polydactyly, ectodermal dysplasia and cardiac anomalies. We present the case of a 24 years old female patient with unaffected parents and an affected sister, with a personal history of surgically corrected postaxial polydactyly of both hands and atriventricular canal. Clinical features were: a marked acromesomelic short stature (135 cm height), narrow thorax, genu valgum, club feet, brachydactyly, malposed toes, hypoplastic nails and teeth, diffuse alopecia, atrioventricular canal, hypoplastic mammary glands and a small goiter. Radiologic evaluation revealed short metacarpals and phalanges, capitat and hamat fusion on the left, left ulnar epiphysis with areas of osteolysis and osteocondensation, genu valgum, short fibulae, narrow thorax, cardiac enlargement with hilar congestion. Echocardiogram showed absence of the atrial sept and the basal portion of the ventricular sept and electrochardiogram--right bundle branch block, left anterior fascicular block and left ventricular hypertrophy. Free thyroxine, TSH and usual laboratory parameters were in the normal range with exception of ionic calcium which was low (3.8 mg/dL).

Turner syndrome is due to haploinsufficiency of X chromosome genes that escape inactivation and associates female phenotype, short stature, gonadal dysgenesis, somatic stigmata, cardiovascular and renal anomalies and a large spectrum of other disorders (autoimmune thyroiditis, osteoporosis, inflammatory bowel disease, chronic liver diseases). The increased mortality in Turner syndrome is primarily a result of its cardiovascular complications. Congenital cardiac anomalies (coarctation of the aorta, bicuspid aortic valve, anomalous venous drainage) are present in 23-40% of patients; there is an increased risk of aortic dilation (42%) and dissection, ischemic heart disease and the risk of hypertension is increased three fold. In addition, insulin resistance may be present in up to 50% of women with Turner syndrome and an atherogenic lipid profile (increased cholesterol, triglycerides) favors the development of coronary artery disease. Our study was aimed to reveal anomalies in Turner syndrome that may increase cardiovascular risk. We studied a group of 62 Turner patients aged 16-67 years (mean age 26.8 years, SD = 11.1 years) comparatively to 62 age matched controls. Glycemia over 100 mg% was found in 11.3% of Turner patients vs 1.6% of controls and cholesterolemia over 200mg% was found in 51.2% of Turner patients vs 14.5% of controls; 24.2% of Turner patients were overweight vs 17.8% of controls and 6.4% were obese vs 4.8% of controls. In the Turner group we found congenital cardiac anomalies in 17.8%, hypertension in 6.5%, renal anomalies 11.3%, and hypothyroidism 29.2%.

The metabolic syndrome (MetS) is a huge public health problem worldwide, being one of the major causes of cardiovascular disease, responsible for a growing number of premature deaths throughout the world. MetS includes a cluster of anomalies, such as: abdominal obesity, insulin resistance, hyperinsulinemia, hypertension, type 2 diabetes mellitus or glucose intolerance, hypertriglyceridemia etc. The number of people with MetS increases with age, affecting more than 40% of people in their 60s and 70s. About 30% of European people over 50 have MetS. Some experts estimate that as many as two thirds of Americans may be suffering from MetS. The exact cause of MetS is not known: genetics play a minor role, acquired in-utero factors also play a role (prenatal malnutrition, toxin exposure, exposure to high levels of maternal cortisol). For most people, the MetS results primarily from lifestyle factors, such as: chronic stress, inadequate exercise. The MetS can be avoided and reversed in most cases. Weight loss is both a treatment and goal for MetS patients. Moderate weight loss, in the range of 5-10% of body weight, can help restore body's ability to recognize insulin and greatly reduce the chance that the syndrome will evolve into a more serious illness. In most people weight loss will lower blood pressure and improve triglyceride levels. Increased activity alone can improve insulin levels. Physical activity result in a weight loss, improved blood pressure, improved cholesterol and triglyceride level and reduced risk of developing diabetes. It is also important to treat: hyperlipidemia, hypertension, prothrombotic state.

Klinefelter syndrome is a hypergonadotropic hypogonadism determined by the presence of one or more extra X chromosomes and has an incidence of 1:800 males. It was shown that in Klinefelter syndrome mortality is increased due to diabetes, cardiovascular, respiratory and digestive diseases. Our goal was to assess the presence of metabolic changes which can increase cardiovascular risk. We compared 31 untreated Klinefelter patients aged 19-54 years (mean age 33.84 years, SD 11.79 years) with 31 age matched controls. Hypercholesterolemia was present in 56.67% of Klinefelter patients and correlated with age and the magnitude of androgenic deficit. None of the patients had diabetes mellitus but glycemic values above 100 mg% were present in 16.13% of cases (vs 3.2% in controls). 35.5% of Klinefelter patients and controls were overweight and 16.1% of Klinefelter patients were obese vs 9.7% of controls.

Erectile dysfunction (ED) is 2-3 times more frequent in men with diabetes mellitus than in men without such a history and might be an early marker of endothelial dysfunction. We studied a group of 310 unselected male patients within the Clinical Center of Diabetes and Metabolic Diseases of Dolj County, with ages ranging between 20-78 years (57.43 + 0.835) and a positive history of diabetes mellitus for 1-47 years (10.09 +/- 8.715). Erectile dysfunction, quantified using SHIM (Sexual Health Inventory for Men), was present in 196 patients (63.2%); severe in 52 patients (16.8%), moderate in 42 patients (13.5%) and mild in 102 patients (32.9%). Erectile dysfunction showed a positive correlation with age after 65 years, history of diabetes of more than 10 years, obesity, stroke, arteriopathy, retinopathy, neuropathy and the smoking habit and was not correlated to the type of diabetes mellitus, history of diabetes less than 10 years, diabetes therapy, hypertension, ischemic heart disease, nephropathy, dyslipidemia and alcohol consumption. Our results plead for a holistic approach of the diabetic patient, irrespective of age, in order to detect and to treat all the risk factors, keeping in mind that the appearance of erectile dysfunction might indicate the presence of occult chronic diabetes complications.
