Nevertheless, our case, along with the limitations described, joins other reports, and raises questions about possible interaction between a convulsion disorder and a potent bone resorption inhibition administration, leading to a relative hypocalcemia and possible seizure threshold reduction.

Our interpretation of the scenario described is based on clinical judgment and not supported by ancillary studies.

To present a patient with sarcoidosis-induced hypercalcemia who responded to methotrexate (MTX).

The described case includes clinical and biochemical reports.

A 65-year-old woman presented with bilateral hilar lymphadenopathy and pulmonary nodules. Her calcium and phosphorous levels were 11.4 mg/dL and 3.5 mg/dL, respectively. Blood levels of 25-hydroxyvitamin D and parathyroid hormone were 68 nmol/L and 23 pg/dL, respectively. A diagnosis of sarcoidosis was confirmed by a lymph node biopsy that revealed non-caseating granulomas. Prednisone therapy was efficacious in normalizing the calcium level. However, hypercalcemia recurred when the prednisone dosage was tapered to below15 mg daily. Following initiation of MTX at 15 mg/week, prednisone levels were successfully titrated to 3 mg daily. After a temporary withdrawal of MTX therapy, calcium levels increased dramatically to 17 mg/dL.

MTX can be used as treatment for sarcoidosis-induced hypercalcemia.

Dystrophic scoliosis is a serious skeletal manifestation of neurofibromatosis 1 (NF1). The condition requires surgical intervention that is frequently associated with poor outcome due to the high rate of impaired bone healing, pseudoarthrosis, and loosening of the spinal instrumentation. New therapeutic approaches are needed to improve surgical outcomes.

Clinical, laboratory, and radiographic data are presented.

A 54-year-old woman with severe NF1 related dystrophic scoliosis and 3 prior surgical interventions underwent revision of lumbar fusion with intraoperative recombinant human bone morphogenetic protein (rhBMP-2) for loosening and a fracture of the left vertical rod at the L4 pedicle screw connection. Two days after surgery, a computed tomography (CT) scan revealed a left posterior iliac periscrew fracture. Given a high risk of mechanical failure, zoledronic acid and asfotase alfa were also administered at 3 and 7 months after surgery. At 14 months after surgery, back pain improved, and a CT scan showed stable spinal fusion and a healed left posterior iliac screw fracture.

Combination therapy including asfotase alfa with rhBMP-2 and bisphosphonate resulted in solid arthrodesis after spinal surgery in NF1-related dystrophic scoliosis.

Treatment of metastatic adrenocortical carcinoma (ACC) is challenging and long-term survival rates are exceedingly low. Long-term outcome data for pediatric patients who received mitotane is very limited.

We describe the case of a 2-year-old boy with ACC with a lung metastasis. He was treated with surgery, chemotherapy, and mitotane, and remains disease-free 13 years after diagnosis.

The key endocrine issues learned from this case include adrenal-derived sex-steroid and insulin-like growth factor-2 levels are correlated with disease status; very high doses of glucocorticoid and mineralocorticoid are required while on treatment of mitotane; and central precocious puberty needs to be detected and treated in a timely manner to preserve final adult height.

We report a case of pediatric ACC with metastasis that was successfully treated with surgery, chemotherapy, and adjuvant therapy with mitotane. Appropriate endocrine testing and management are important for long-term survival and quality of life.

We report a case of adipsic diabetes insipidus (ADI) post-astrocytoma resection.

Clinical and laboratory data are presented.

A 16-year-old female with a history of incompletely resected hypothalamic astrocytoma was admitted with a headache. Head magnetic resonance imaging showed an interval increase in a suprasellar lesion with extension to the third ventricle. Following a second stage resection, she developed an increased urine output with diluted urine resulting in a negative fluid balance; however, she was unable to sense thirst. Blood tests showed a serum sodium of 155 mEq/dL (normal, 136 to 145 mEq/dL), serum osmolality at 321 mOs/kg (normal, 285 to 295 mOs/kg) and a urine osmolality of 128 mOsm/kg (normal, 300 to 1,600 mOsm/kg). Serum creatinine and potassium were normal. Pituitary hormone profiles were found to be normal growth hormone 0.171 ng/mL (normal, 0.123 to 8.05 ng/mL), luteinizing hormone 3.44 mIU/mL (normal, 7.59 to 89.08 mIU/mL), follicle-stimulating hormone 5.60 mIU/mL (normal, 2.55 to 16.69 mIU/mL), thyroid-stimulating hormone 2.9 mIU/mL (normal, 0.35 to 4.94 mIU/mL), free thyroxine 0.92 ng/dL (normal, 0.7 to 1.48 ng/dL), adrenocorticotropic hormone 19.56 pg/mL (normal, 7.2 to 63.3 pg/mL), and prolactin 7.25 ng/mL (normal, 5.18 to 26.53 ng/mL). The patient was treated with desmopressin acetate 120 μg tablets twice daily with a fixed fluid intake of 1.5 to 2.0 L/day with close monitoring of fluid intake, output, and body weight. The response was good with a gradual reduction of serum sodium level of around 7 to 9 mEq/L/day.

ADI is a rare entity of central diabetes insipidus, where the absence of polydipsia can be challenging in diagnosing and managing the condition. Cases of ADI are likely under reported and clinicians need to be aware of this condition.
