Some cutaneous lesions accompany or reveal endocrine disorders. Identifying the endocrinopathy is very important because it sometimes allows corrective rather than symptomatic treatment. The most frequenly involved diseases include thyrotoxicosis, hypothyroidism, the auto-immune disorders of thyroid, Cushing syndrome, Addison disease, acromegaly, androgen-dependent disorders, hypopituitarism, hypoparathyroidism, pseudohypoparathyroidism and diabetes mellitus.

Herein we describe the case of a 64-year-old woman with hypoparathyroidism diagnosed at the age of 40, after an acute episode of tetany and seizures due to severe hypocalcemia. She was treated for more than 20 years with calcitriol and calcium supplementation but she presented with marked hypercalciuria and recently nephrolithiasis, although serum calcium was maintained at levels below normal range. Provided that any attempt to increase the recommended dose of calcitriol was leading to an exacerbation of hypercalciuria, we decided to enroll an alternative tool in the treatment strategy. In order to avoid further deterioration of renal function she was administered once-daily a subcutaneous (sc) injection of synthetic human parathyroid hormone (PTH 1-34) while doses of calcium and calcitriol were gradually decreased depending on the response of calcium metabolism in serum and urine samples taken periodically. Within two months of administration, PTH (1-34) significantly reduced the level of urine calcium excretion compared with calcitriol therapy and maintained serum calcium in the normal range. The relevant literature is reviewed in light of this alternative therapeutic approach in long-standing hypoparathyroidism, illustrating the potential benefits and the unresolved issues in parathyroid hormone replacement.

Hemolytic anemias can induce various anomalies of the endocrine glands which can already be observed in children. Endocrine dysfunction is also found in the course of therapy for aplastic anemias, usually as undesirable side effects. In Europe, 2-9% of the population belongs to ethnic minorities at risk for developing hemolytic anemia. Pituitary affinity to iron deposition explains the high incidence of hypogonadism, puberty delay and growth retardation although other factors have to be considered. Growth hormone deficiency has to be ruled out as it can occur in a minority of subjects with thalassemia and sickle-cell disease (drepanocytosis). Diabetes mellitus, hypothyroidism and hypoparathyroidism may also develop. Follow-up includes close monitoring of growth and pubertal development in order to guide therapeutic interventions.

Patients with multi-transfused thalassaemia major may develop severe endocrine complications due to iron overload. The anterior pituitary is particularly sensitive to iron overload which disrupts hormonal secretion resulting in hypogonadism, short stature , acquired hypothyroidism and hypoparathyroidism. Glucose intolerance and diabetes mellitus are also common in thalassaemic patients. The severity of the clinical manifestation and laboratory findings in thalassaemia largely depends on the genotype; thus homozygotes or compound heterozygotes for the mutations beta0 or beta+ depend for life on frequent transfusions. A multicenter study in Cyprus including 435 patients showed hypogonadotrophic hypogonadism in 32.5%, short stature in 35%, acquired hypothyroidism in 5.9%, hypoparathyroidism in 1.2% and diabetes mellitus in 9.4%. A slowing down of growth velocity and a reduced or absent pubertal growth spurt is observed in early adolescence leading to short adult height. Delayed or absent puberty and hypogonadism may result in fertility problems which affect enormously the life of thalassemics. Glucose intolerance in adolescence and diabetes mellitus later in life are also frequent complications mainly due to iron overload, chronic liver disease and genetic predisposition. Primary hypothyroidism and hypoparathyroidsm usually appear in the second decade of life; are related to iron overload and may be reversible at an early stage by intensive chelation. Osteopenia and osteoporosis due to a complicated pathogenesis represent prominent causes of morbidity in young adults of both genders with thalassaemia. Early recognition and prevention of the endocrine complications, by early and regular chelation therapy, is mandatory for the improvement of the quality of life and psychological outcome of these patients.

A 30-year-old normocalcemic man with hypopituitarism, hypogonadism, diabetes mellitus, and secondary hemochromatosis due to multiple blood transfusions was admitted because of adrenal crisis. After intravenous administration of saline and cortisol, the corrected serum level of calcium decreased to 7.3 mg/dl. This osteoporotic patient had been prescribed alendronate for radial bone fracture. Since the increase in intact PTH (68 pg/ml) was impaired compared to that seen in hypocalcemic patients with secondary hyperparathyroidism, we presume that the patient has had latent hypoparathyroidism, which was unmasked by the administration of glucocorticoid and bisphosphonate. With a supplemented dose of 1alpha-OHD3, the patient has been eucalcemic.

Thalassemia is common in Iran. Appropriate therapy for this disease includes a regular blood transfusion and chelation therapy. However, in this approach patients will inevitably experience side effects, particularly iron overloads in critical organs, including heart, ductless glands, and liver. This study attempted to determine prevalence of adenoidal abnormality between Iranian thalassemia patients for prediagnosis and to offer necessary medical measures. This is a descriptive nonrandomized study and included all the patients suffering from thalassemia major referring to medical centers linked with the Iranian blood transfusion organization from January 2004 to January 2005. All patients were sampled for CBC, FBS, 2-h BS, HbAlC, liver function, renal function, and endocrine disease. Initially, reports of adenoidal experiments as well as other associated parameters were provided from medical records. A total of 437 patients enrolled in the study: 5.4% suffered from diabetes, 1% had hypothyroid, and 1 person showed hypoparathyroidism. The mean levels of ferritin in diabetic and nondiabetic groups and hypothyroid and nonhypothyroid groups were not significantly different. The mean levels of ferritin among various age groups also were not significantly different. Results of a comparison between present research and similar studies conducted throughout Iran and those performed abroad on adenoidal abnormalities in thalassemia patients show that subject patients of this study statistically suffered from fewer difficulties than diabetes patients in other studies.

Type 1 diabetes (T1D) is associated with autoimmune thyroid disease (AIT), celiac disease (CD), Addison's disease (AD), and other autoimmune diseases. These diseases can occur simultaneously in defined syndromes with distinct pathophysiology and characteristics: autoimmune polyendocrine syndromes (APSs) and the immunodysregulation polyendocrinopathy enteropathy X-linked syndrome (IPEX). APSs were initially defined as a multiple endocrine gland insufficiency associated to an autoimmune disease in a patient. APS-1 is characterized by the evidence of chronic candidiasis, chronic hypoparathyroidism, AD and T1D could be present as part of this syndrome. The combination of autoimmune adrenal insufficiency with AIT and/or type 1 autoimmune diabetes mellitus defines APS-2. AIT associated to other autoimmune diseases (excluding AD and/or hypoparathyroidism) are the main characteristics of APS-3. Different clinical combinations of autoimmune diseases which were not included in the previous groups are the characteristics of APS-4. IPEX is a recessive disorder characterized by the neonatal onset of T1D, infections, enteropathy, thrombocytopenia and anemia, as well as endocrinopathy, eczema and cachexia. These disorders are not common, but their consequences can be life threatening when the diagnosis is overlooked, and the treatment is the same prescribed for isolated disease presentation.

Patients with Down's syndrome are at higher risk for developing autoimmune diseases than those of the general population. Autoimmune diseases like Hashimoto's thyroiditis, Graves' disease, diabetes mellitus type I, celiac disease, autoimmune chronic active hepatitis, alopecia, vitiligo and hypoparathyroidism are recognized associations with Down's syndrome. We describe the case of a very young boy with Down's syndrome who was diagnosed with diabetes mellitus type I, Hashimoto's thyroiditis and celiac disease before 8 yr of age. Unspecific symptoms like weight loss, unstable blood sugar with high amplitudes, behavioural problems and dry skin were suspicious for other endocrine disorders or celiac disease in our case. The boy was showing the typical human leukocyte antigen profile for these autoimmune diseases. The prevalence of these autoimmune diseases is higher in Down's syndrome than in general population. Therefore, we advice to follow children with Down's syndrome who develop more than two autoimmune diseases very carefully.

Several studies suggest that mild PTH excess does not have any deteriorative effects on bone mineral density (BMD) in several-year-longitudinal studies of patients with mild primary hyperparathyroidism (pHPT) without parathyroidectomy (PTX). However, it remains unknown about the change in bone geometry in pHPT patients without PTX. We examined the longitudinal effects of mild PTH excess on cortical bone geometry in postmenopausal patients with mild pHPT without PTX by using peripheral quantitative computed tomography (pQCT), and we compared them with normal and hypoparathyroidism women. Nine postmenopausal female patients who were diagnosed as pHPT, six postmenopausal female patients with hypoparathyroidism (3 idiopathic and 3 postoperative), and thirty postmenopausal control subjects participated in this study. Radial volumetric (v) BMD and several bone geometry parameters were measured by pQCT at basal line and after 2 years. Cortical vBMD was significantly lower in pHPT group. Moreover, total area and periosteal circumferences were significantly higher in pHPT group. Total and cortical vBMD were significantly decreased after 2 years in control group. However, they were stable in pHPT group after 2-year follow-up. As for bone geometry, cortical thickness and area were also stable in pHPT group during 2-year follow-up, although they were significantly reduced in control group and hypoparathyroidism group. In conclusion, the present longitudinal study revealed that there were no significant changes in radial vBMD and cortical bone geometry in postmenopausal women with mild pHPT, whereas age-related thinning of cortical bone as well as decrease of vBMD were observed in the control and patients with hypoparathyroidism.

273 patients with thalassaemia major followed from diagnosis in the Ferrara Centre were divided into 3 cohorts (C) according to the year of birth (C1=1954-1964, 85 patients; C2=1965-1974, 129 patients; C3=1975-2001, 59 patients) in order to study the trends of endocrine complications. Menarche occurred in 52 out of 112 patients (46%), without significant differences among the 3 groups, at the mean age of 13.9+/-1.4 years. Sixty-five percent of these patients had secondary amenorrhoea at the mean age of 18.8+/-3.7 years. In males complete pubertal development occurred in 48% of patients (C1:31%, C2: 44%, C3: 63%, p<0.05) followed by secondary hypogonadism in 24% of patients above 21 years of age. Primary (80%) and central 20%) hypothyroidism were diagnosed in 31% of patients (C1: 55%, C2: 31.5%, C3: 13.4%, p<0.05), diabetes mellitus (DM) in 17% of patients (C1: 28.6%, C2: 17.2%, C3: 3.4%, p<0.05), and hypoparathyroidism in 10.6% of cases (C1: 18.7%, C2: 10.1%, C3: 3.4%, p<0.05). No difference was found in patient mean age of diagnosis of hypothyroidism, DM or hypoparathyroidism (20.4+/-8.2 years, 19+/-5 yrs and 18.5+/-5.8 yrs respectively) but in all three groups age at diagnosis significantly increased over time (hypothyroidism and DM: p<0.001; hypoparathyroidism: p<0.01). Over time the prevalence of hypothyroidism, diabetes mellitus and hypoparathyroidism increased to 24.4%, 14.7%, and 6.7%, respectively, at the time of the study. Incidences peaked in the early 1980's, and declined in the following years (primary hypothyroidism from 6.5% in 1981 to 0.9% in 2007, p<0.01; DM from 3.9% in 1986 to 0.8% in 2007, p<0.05; hypoparathyroidism 2.4% in 1984 to 0% in 2007, p<0.01) and correlated with the decrease in annual mean serum ferritin levels in all patients (p<0.001). The main risk factors associated with endocrine complications were high serum ferritin levels, poor compliance with desferioxamine (DFO) therapy, early onset of transfusion therapy (only for hypogonadism) and splenectomy (only for hypothyroidism). Serum ferritin levels of approximately 2000 ng/ml were found to correlate with hypogonadism, and 3000 ng/ml for hypothyroidism, hypoparathyroidism and DM. The incidences of hypothyroidism, DM and hypoparathyroidism were not significantly different in 18 patients on long term treatment with deferiprone (DPO) compared with 64 patients continuously treated with DFO, from 1995 to 2007. In conclusion, our longitudinal study shows that in the last 30 years in the Ferrara Centre the incidences of hypothyroidism, diabetes mellitus, and hypoparathyroidism declined, and pubertal development in males with thalassemia major improved in patients, on DFO treatment, born after 1976. The efficacy of alternative chelation regimes with deferiprone or deferasirox to monotherapy with desferioxamine remains to be established.
