Abdominal composition quantified by computed tomography.

Abstract

Abdominal composition was quantified from computed tomography (CT) scans of 96 clinically normal men and women aged 20-83 y. Measurements were taken of total and intraabdominal areas and of muscle, bone, and subcutaneous and intraabdominal adipose-tissue areas from each of six 8-mm-thick transverse slices from CT images of abdomen and pelvis. Men had a significantly greater percentage of intraabdominal adipose tissue than women and the percentage increased with age in each sex. Percentages of total abdominal area that were adipose tissue were significantly negatively correlated with percentages of muscle and bone in each sex. Ratios of total areas of abdominal slices to total areas of pelvic slices (analogous to waist:hip ratios) had significant positive correlations with the absolute and relative areas of intraabdominal and subcutaneous adipose tissue for the abdomen in women but not in men. These ratios also had significant negative correlations with absolute and relative areas of muscle and bone in women.

[Extrapulmonary tuberculosis. An important differential diagnosis in immigrants with suspected malignancy].

The incidence of tuberculous disease is increasing all over the world, mostly in the poor, developing countries, but also in some industrialized countries. In Norway, extrapulmonary tuberculosis is a rare phenomenon. It is found mostly among older Norwegians and in younger immigrants from the third world. Since the disease is rare, it may be overlooked or confused with malignant disease. We describe two patients with unusual forms of extrapulmonary tuberculosis, both mimicking neoplastic disease. The first patient was a 27-year-old woman from South-East Asia, who was operated on for suspected intraductal comedo-type carcinoma of the breast, but histological examination showed tuberculous mastitis. The second patient was a 26-year-old man from East Africa with a medical history indicating intra-abdominal lymphoma. The final diagnosis, however, was mesenteric tuberculous lymphadenitis. Both patients were treated successfully with isoniazid, rifampicin and pyrazinamide.

The identification of two myoinhibitory peptides, with sequence similarities to the galanins, isolated from the ventral nerve cord of Manduca sexta.

Two new myoinhibitory peptides, Mas-MIP I and Mas-MIP II, were identified from the ventral nerve cord of the adult tobacco hornworm, Manduca sexta. Sequences obtained by a combination of automated Edman degradation and electrospray mass spectrometry were, respectively, AWQDLNSAW and GWQDLNSAW. The native peptides were found to co-elute with synthetic C-terminal amides on a reverse phase HPLC system. When applied to isolated ilea (anterior hindgut) of adult M. sexta, both peptides were found to significantly reduce the rate of peristalsis, or abolish peristalsis entirely, at concentrations of 1 x 10(-9) M. Both peptides share sequence similarities with Lom-MIP, a previously identified myoinhibitory peptide from Locusta migratoria, and with the N-terminal portion of vertebrate peptides in the galanin family.

Abdominal multivisceral transplantation.

Under FK506-based immunosuppression, 13 abdominal multivisceral transplantations were performed in 6 children and 7 adults. Of the 13 recipients, 7 (53.8%) are alive and well with functioning grafts after 9 to 31 months. Six recipients died: three from PTLD, one from rejection, one from sepsis, and one from respiratory failure. In addition to rejection, postoperative complications occurring in more than isolated cases included PTLD (n = 6), abdominal abscess formation (n = 5), pancreatitis (n = 3), and ampullary dysfunction (n = 2). In addition, infection by enteric microorganisms was common during the early postoperative period. Currently, all 7 survivors are on an oral diet and have normal liver function. Two recipients (one insulin-dependent) require antidiabetes treatment, in one case following distal pancreatectomy and in the other after two episodes of pancreatic rejection. Thus, abdominal multivisceral transplantation is a difficult but feasible operation that demands complex and prolonged posttransplantation management. It is not yet ready for application and awaits a better strategy of immune modulation.
