Tyrosinaemia type 1 (TT1) is a rare inherited disorder of amino acid metabolism typically presenting with liver failure and renal tubular dysfunction. We describe three individuals with TT1 and transient hyperinsulinaemic hypoglycaemia (HH). Two siblings with TT1 and acute liver dysfunction were diagnosed with hyperinsulinaemic hypoglycaemia in the neonatal period. Both siblings were successfully treated with diazoxide/chlorthiazide and treatment was gradually weaned and stopped after 8 and 6 months of age respectively. The third patient presented with a neonatal liver failure with mild cholestasis, coagulopathy, fundus haemorrhages, vitamin A and E deficiency and hyperinsulinaemic hypoglycaemia. He maintained euglycaemia on high dose diazoxide (5-12 mg/kg/day) but developed pulmonary hypertension at 12 weeks of age. After discontinuation of diazoxide, he continued maintaining his blood glucose (BG) within the normal range. Although histological abnormalities of the pancreas including beta-cell hyperplasia yet and further studies are required to determine which factors contribute to excessive insulin secretion in patients with TT1.
Every child with TT1 should be monitored for signs and symptoms of hypoglycaemia and screened for HH at the time of real hypoglycaemia. If hypoglycaemic episodes persist even after improvement of liver function, hyperinsulinism should be suspected. JHU-083 manufacturer Treatment with diazoxide is effective, however, children need to be monitored closely for possible side effects. The pathophysiological mechanism of hyperinsulinism in children with TT1 is not elucidated yet and further studies are required to determine which factors contribute to excessive insulin secretion in patients with TT1.
Wilson's disease (WD) is a rare disorder of copper metabolism usually presenting with variable liver damage and neuropsychiatric symptoms. Here we report a 39-year-old Taiwanese female with late manifestation of WD presenting with gonadotroph, thyreotroph and corticotroph hypopituitarism. Molecular genetic testing revealed compound heterozygosity for two mutations in exons 12 and 14 (c.2828G>A and c.3140A>T). Copper-chelating therapy with D-penicillamine and zinc was initiated along with supplementation of hydrocortisone and L-thyroxine. Hypopituitarism resolved when urinary copper excretion returned to normal levels under copper chelation. This case should raise awareness of pituitary function in WD patients.
Hypopituitarism can complicate Wilson's disease (WD) and endocrinologists should be aware of it when caring for hypopituitary patients. Hepatologists should consider endocrinologic testing for hypopituitarism when WD patients present with symptoms of adrenal insufficiency, thyroid or gonadal dysfunction. Copper-chelating treatment is mandatory and may lead to the recovery of pituitary function in such patients.

We present the case of a 69-year-old woman who attended the Endocrinology Unit of Modena for a suspicious lymph node in the left cervical compartment discovered during the follow-up of a recurrent gynecological malignancy. At neck ultrasonography, a thyroid goiter was detected, and the further cytological examination was inconclusive for thyroid nodule and compatible with a localization of an adenocarcinoma with papillary architecture for the lymph node. The histological examination after a left neck dissection confirmed the presence of an intracapsular metastasis of a papillary carcinoma immunohistochemically focally positive for thyroid transcription factor 1 and paired box 8 and negative for thyroglobulin. Subsequently, in the suspicion of a thyroid primitiveness, a total thyroidectomy was performed, revealing an intraparenchymal follicular variant of papillary thyroid carcinoma of 2 mm in the right lobe. During the follow-up, the appearance of a suspected cervical metastatic lesion led to another neck deutic path and to avoid unnecessary treatments.
Neck lymph node metastases occasionally originate from anatomically distant primary sites, such as breast, lung, gastro-intestinal tract, genito-urinary tract and CNS. Histological and immunohistochemical evaluations play an important role to identify the primary malignant site, although in some cases they could mislead the clinicians. A multidisciplinary approach and the evaluation of the whole medical history of the patient are mandatory to guide the diagnostic-therapeutic path and to avoid unnecessary treatments.
Thyroid storm is a rare but potentially life-threatening complication of excessive thyroid hormone action. It is associated with a hypercoagulable state and reported to increase the risk of thromboembolism. However, the role of anticoagulation in thyroid storm still remains controversial and inconclusive. A 22-year-old male with no significant past medical history presented with acute severe generalised abdominal pain. He was found to be profoundly thyrotoxic on arrival at our institution and subsequently diagnosed with thyroid storm secondary to newly diagnosed Graves' disease. Extensive thromboses of the splanchnic, iliac, femoral veins and pulmonary arteries were subsequently demonstrated on CT scan. He had prolonged bowel ileus as a sequela of mesenteric ischaemia requiring total parenteral nutrition and non-oral forms of anti-thyroid drugs for management of hyperthyroidism. He was in sinus rhythm throughout his inpatient stay, and there was no personal history of prothrombotic conditions. His thrombophilia screen was normal.
