Laparoscopic Revision of Bariatric Surgeries in Two Patients with Severe Resistant Hypocalcemia After Endocrine Cervical Surgery.

Severe hypocalcemia complicating cervical endocrine surgery in patients with gastric bypass can constitute a major concern. When usual therapies fail to maintain calcemia within the normal range without secondary adverse events, reversal of the bariatric surgery should be considered. We herein report the outcomes of laparoscopic revision of bariatric surgeries in two patients suffering from severe resistant hypocalcemia following cervical surgery, requiring in one case recombinant PTH administration and, in the other, daily intravenous calcium injections. The Roux-en-Y gastric bypass was switched to sleeve gastrectomy in the first patient, and in the second patient, the biliopancreatic diversion with duodenal switch was revised, to restore the upper and distal parts of the alimentary tract. Rapid improvement of hypocalcemia was observed in both cases.

Foetal exposure to mitotane/Op'DDD: Post-natal study of four children.

OBJECTIVE: Mitotane/Op'DDD is used in the treatment of adrenocortical carcinoma and for other causes of hypercortisolism. Mitotane inhibits cortisol secretion and displays adrenolytic and antitumor actions. This compound is a metabolite of the pesticide and endocrine disruptor DDT (dichlorodiphenyltrichloroethane) and is classified among teratogenic compounds worldwide. However, little is known about its effects on human development. DESIGN: The outcome of four children exposed to mitotane during their intrauterine life was examined. PATIENTS: Patients having conceived while taking mitotane, or with detectable mitotane plasma levels, were retrospectively recruited via the French COMETE and FIRENDO networks. MEASUREMENTS: Mitotane in maternal plasma, adrenocortical hormones in children. RESULTS: Three women treated with mitotane gave birth to four children. During early pregnancy, all patients had detectable mitotane plasma levels (0.9, 2.4 and 6.7 mg/L, respectively). During pregnancy, no foetal malformations were detected. The four exposed newborns presented at birth with apparently normal adrenal function and genitalia. One twin female had a low birthweight. Evaluation at birth and after 3 months, 2 years and 7 years of follow-up showed no significant neurological abnormality. Evaluation of adrenocortical functions showed no cortisol deficiency. CONCLUSIONS: Unexpectedly, exposure of these four children to mitotane during foetal life seemed to have no clear teratogenic effect. However, considering the sub-therapeutic mitotane concentrations used here, the small number of cases, and because long-term follow-up is unknown, we strongly advise not to take mitotane during pregnancy and still recommend avoiding pregnancy, at least as long as mitotane plasma levels remain detectable.
