RESUMEN

A direct correlation exists between collagenization of Disse's space and the presence of diabetic microangiopathy in type I diabetes. To confirm and extend this finding, we studied four liver biopsy samples from two patients with type I diabetes (one with retinopathy) and two patients with type II diabetes (no retinopathy). All had normal or subnormal results on liver function tests and normal liver architecture. Levels of collagen types I, III, and IV, laminin, and fibronectin, as determined by immunocytochemical techniques, appeared increased in all patients. Liver biopsy samples were perfusion fixed for electron microscopy of sinusoids and sinusoidal cells. Numerous and thick collagen bundles could be seen in Disse's space, as could the increase of basement membrane-like material underlying the endothelial cells, perisinusoidal cells, and sinusoidal membrane of hepatocytes. Perisinusoidal cells were active and had abundant rough endoplasmic reticula and thick processes. This preliminary study indicates that collagenization of Disse's space is not specific to a certain type of diabetes. The increase of basement membrane-like material raises the question of whether liver sinusoids are truly different from other capillaries as far as diabetic microangiopathy is concerned.

RESUMEN

A moderate increase in transaminases and alkaline phosphatase serum concentrations was observed in 14 of 32 patients with psittacosis (antibodies anti-Chlamydia psittaci greater than or equal to 1/40 with the complement fixation test). Clinical manifestations were present in 4 patients (hepatomegaly in 4 cases; jaundice in one case). In one patient, histological examination of a liver specimen showed granuloma. In 13 patients treated with tetracycline or macrolides, the outcome was favorable. One patient recovered spontaneously. In comparison with the group of 18 patients without hepatic involvement, there was no difference pertaining to epidemiological, clinical, or serological findings. Equally, there was no difference in the course of the disease.

RESUMEN

BACKGROUND: The aim of this study was to evaluate the efficacy of adjuvant chemotherapy after resection for gastric cancer in a randomized controlled trial. PATIENTS AND METHODS: After curative resection, stage II-III-IVM0 gastric cancer patients were randomly assigned to postoperative chemotherapy or surgery alone. 5-Fluorouracil (5-FU) 800 mg/m(2) daily (5-day continuous infusion) was initiated before day 14 after resection. One month later, four 5-day cycles of 5-FU (1 g/m(2) per day) plus cisplatin (100 mg/m(2) on day 2) were administered every 4 weeks. RESULTS: The study was closed prematurely after enrollment of 260 patients (79.7% N+), owing to poor accrual. At 97.8 months median follow-up, 5- and 7-year overall survival were 41.9% and 34.9% in the control group versus 46.6% and 44.6% in the chemotherapy group (P=0.22). Cox model hazard ratios were 0.74 [95% confidence interval (CI) 0.54-1.02; P=0.063] for death and 0.70 (95% CI 0.51-0.97; P=0.032) for recurrence. An invaded/removed lymph nodes ratio >0.3 was the main independent poor prognostic factor identified by multivariate analysis (P=0.0001). Because of toxicity, only 48.8% of patients received more than 80% of the planned dose. CONCLUSION: There was no statistically significant survival benefit with this toxic cisplatin-based adjuvant chemotherapy, but a risk reduction in recurrence was observed.

RESUMEN

Thirty patients (17 male, 13 female; age 17 to 84 years; normal renal function in 23 cases) with severe bacterial infections were treated with ceftriaxone. The infections was septicemia in 20 cases, a septicemia-like condition in 2 and a focal infection in 8 (2 abscesses of the lung, 2 pyelonephritis, 1 abscess of the liver, 1 subphrenic abscess, 1 meningitis developed from an abscess of the brain and 1 acute intestinal infection). 25 infections were bacteriologically documented, with recovery of the following pathogens: 20 Gram negative rods (including 10 E. coli) that were all susceptible to ceftriaxone (MIC = 0.02 to 0.5 mg/l) except 2 (1 Pseudomonas and 1 E. cloacae), 5 susceptible Gram positive cocci (3 Pneumococcus, 1 Streptococcus and 1 Staphylococcus epidermidis) and 3 susceptible anaerobes (2 B. fragilis and 1 B. melaninogenicus). Ceftriaxone was given alone in 15 cases and in association with another antibiotic in 15 cases (aminoglycoside in 10 cases, nitroimidazole in 4 and fosfomycin in 1). The dose of ceftriaxone was 1 to 2 g per day in 28 cases, 3 g per day in 1 case (meningitis with abscess of the brain) and 1 g every other day in 1 case (chronic renal failure under hemodialysis). Duration of treatment ranged from 10 to 62 days (average 17 days). The usual routes of administration were IV and IM; the SC route was used on 4 occasions. Pharmacokinetic studies of serum levels were carried out in several patients including two who had ceftriaxone subcutaneously; results were consistent with those previously reported in the literature.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

Seventeen university hospitals have joined their observations of septicemias through an informatics system. 461 septicemias have been collected in 1985. 407 are septic localizations, 299 primitives and 108 secondary. The frequent localisations are urologic (20.4%), pulmonary (20.15%), cutaneous (10.56%), abdominal (10.56%), cardiac and neurologic (9.58%). In 51.8%, the organisms are Gram positive cocci (Staphylococcus 23.9%, Streptococcus 27.9%). In 46.9% septic localizations are due to Gram negative bacilli with Escherichia coli (50.2%). The origin of septicemia is urologic (18%), abdominal (15.8%), cutaneous (8.7%), pulmonary (8.7%), stomatologic (7.2%), venous (4.3%). Gram positive cocci infections have more septic localizations than Gram negative bacilli infections. The mortality is more increased in pulmonary localizations (35%) than in the others localizations: venous (20%), cutaneous (19%), urologic (11%) and stomatologic (10%). Septic localizations which required the most of an antibiotics association are osseous (81.5%) and cardiac (80.5%), where as all septicemias require two antibiotics in 51%.

RESUMEN

Eight cases of pulmonary involvement were observed in 17 severe cases of ictero-haemorrhagic leptospirosis. Haemoptysis (7 cases) occurred on the 4th day of the infectious syndrome and was associated with other haemorrhagic manifestations in 4 cases. Cough, pain and polypnoea were not constant. Chest X-ray showed diffuse, non-specific changes, such as nodular opacities or infiltrates. Septicaemia was confirmed in all cases with acute renal failure in 7 cases and meningitis in 6 cases. Severe thrombocytopenia was demonstrated in 2 cases. Six patients recovered quickly with regression of the lung changes within 12 days. Two patients died, one of a fulminant haemoptysis related to a disseminated intravascular coagulation syndrome, and the other of acute respiratory failure. All cases were confirmed serologically. Although lung changes in leptospirosis are usually benign and mild, haemoptysis and polypnoea with diffuse radiological changes are poor prognostic factors. The pathological changes were similar to those of haemorrhagic alveolitis. These changes may be either due to the liberation of toxins or to an immunological phenomenon.
