[Intraoperative intact parathyroid hormone determination as a predictive factor of hyperparathyroidism resolution].

INTRODUCTION: The objectives of this study were: a) to evaluate the effectiveness of intraoperative intact parathyroid hormone (PTHi) determination as a marker of hyperparathyroidism resolution; b) to establish the minimum number of blood samples required; and c) to determine whether cervical manipulation increases baseline PTHi levels. PATIENTS AND METHOD: We performed a prospective study in 45 patients. Three intraoperative blood PTHi determinations were performed: at baseline and at 10 and 25 minutes after excising the lesion. To analyze the effects of cervical manipulation, in 19 patients, 2 further determinations were made after 2 minutes of massage on both sides of the neck. A decrease of > 50% in PTHi values between postexeresis samples and the baseline sample (gradient > 50%) was used as diagnostic and therapeutic criteria and normalization of calcemia was used as a criteria for complete resolution. RESULTS: Whenever the lesion causing hyperparathyroidism was extirpated, PTHi levels decreased at 10 and 25 minutes after exeresis. This decrease was predictive of complete resolution when the gradient was > 50. Cervical manipulation (massage) did not increase PTHi values. In patients with complete resolution, blood calcium levels also returned to normal. CONCLUSIONS: 1. Intraoperative PTHi determination with a gradient > 50 is an excellent prognostic marker of resolution. 2. Only 2 PTHi samples are required: one at baseline and another at 10 minutes after exeresis. 3. Preoperative cervical manipulation does not increase PTHi values.

Acute necrotizing Meckel diverticulitis due to biliary enterolithiasis.

BACKGROUND: Acute abdominal pain due to complicated Meckel's diverticulum is an unusual event. Even the presence of biliary enterolithiasis at the onset of inflamed congenital diverticulum has rarely been reported previously. RESULTS: Despite this unusual presentation, an episode of gallstone passage through the biliary tract has not yet been described. CONCLUSIONS: Whether the stones were primarily formed in the diverticulum as enterolithiasis, or secondary to gallstone passage is discussed. The complications of Meckel's diverticulum requiring surgical treatment are reviewed, focusing on the unusual finding of biliary stones in Meckel's diverticulum and the etiogenic mechanism of enterolithiasis.

Serratia rubidaea as an invasive pathogen.

Serratia rubidaea biotype 1 was isolated from the bile and blood of a patient with a bile tract carcinoma obstructing the common bile duct and who underwent invasive procedures. The infection was cleared after adequate treatment with antibiotics.

[Alithiasic cholecystitis and sclerosing cholangitis caused by Cryptosporidium and cytomegalovirus in a patient with HIV infection].

A 23-year-old female, an ex-parenteral drug abuser with HIV infection, developed multiple pericholangitic abscesses secondary to lithiasic cholecystitis and sclerosing cholangitis by Cryptosporidium and cytomegalovirus. We emphasize the clinical clues and the diagnostic role of endoscopic retrograde cholangiopancreatography (ERCP), as well as the contribution of the latter to surgical therapy (transendoscopic papillotomy). We also review the reported cases of biliary diseases by Cryptosporidium and/or cytomegalovirus in the literature.

[Zinc deficiency caused by postgastrectomy fistula with high flow in a patient undergoing prolonged parenteral nutrition].

A case is presented of a 57-year-old male patient who underwent total gastrectomy due to gastric adenocarcinoma. During the postoperative period the patient required long-term parenteral nutrition due to a high-debit GI fistula (over 700 ml/day) and sepsis. Two months after parenteral nutrition was started, the patients presented irritability, mucocutaneous lesions and progressive bolding. Serum alkaline phosphatase and zinc levels were lower than normal, although a supplemental 0.03 mg/k/day of zinc was administered. Faced with this zinc deficiency picture, 10 mg zinc sulfate was administered parenterally on a daily basis. The deficiency picture improved markedly over a week's period, and serum zinc and alkaline phosphatase levels returned to normal. The importance of zinc balance control in patients under long-term parenteral nutrition and high fluid debit through GI fistulas is highlighted.
