Over the last decade a great increase in the frequency of Gastric Carcinoid Tumours has been detected being considered by some authors as the most frequent digestive carcinoid. These have been divided into three types: I) those associated with chronic atrophic gastritis; II) associated with Zollinger-Ellison syndrome, and III) sporadic lesions. We present four cases of gastric carcinoid type I (3 women and 1 man) two of them associated with pernicious anemia and another two with iron deficiency anemia. Three patients were operated upon, and an endoscopy removal was carried out on the fourth patient. The clinical course has been favourable during the follow-up. Multiple lesions were detected in 3 patients, with tumours less than 2 cm in size, except for a 4.5 cm polyp, which invaded the submucous layer. This case presented carcinoid syndrome without evidence of liver metastasis. Argyrophilia. Chromogranin A and Neuronal Specific Enolase tintions were located in the tumor and in the hyperplastic endocrine cells of the mucous.

Vitamin D (vitD) deficiency and bone loss may occur after bariatric surgery and hence, supplementation with high oral doses of vitD may be required. Alternatively, intramuscular depot ergocalciferol, which slowly releases vitD and bypasses the gastrointestinal tract, could be administrated. We present a case of severe vitD deficiency-osteomalacia after gastric bypass operation for morbid obesity, treated with ergocalciferol intramuscularly. A 45-year-old woman was presented with hip pain and muscle weakness, which led ultimately to immobilization in a wheelchair. Fifteen years ago, she underwent roux-en-Y gastric by-pass for morbid obesity. Occasionally, she was treated with multivitamin supplements. On admission, iron deficiency anaemia, vitD deficiency (25OHD: 3.7 ng/ml) and secondary hyperparathyroidism were revealed. Bone turnover markers (BTM) were elevated. Radiological evaluation demonstrated insufficiency fractures on the pubic and left femur and reduced BMD. Osteomalacia due to vitD deficiency and calcium malabsorption were diagnosed. Calcium citrate 500 mg qid and intramuscular ergocalciferol 600,000 IU every 20 days were initiated. One month later, musculoskeletal pain and weakness were resolved and the patient was mobilized. Few months later, vitD, BTM and BMD showed substantial improvement. Intramuscular ergocalciferol administration can improve the clinical and biochemical status and thus, is suggested to prevent and/or treat osteomalacia in such patients.
