Pulmonary hemorrhage and glomerulonephritis in primary biliary cirrhosis.

We observed life-threatening intrapulmonary hemorrhages and focal proliferative glomerulonephritis in a 41-yr-old woman with primary biliary cirrhosis. The severity of the symptoms necessitated blood transfusions and mechanical ventilation; the patient improved with the help of corticosteroid therapy. No formal evidence of either Goodpasture's syndrome or any other well-defined systemic vasculitis could be found. Neutrophil cytoplasmic antibodies were initially positive and became undetectable after 3 mo of immunosuppressive treatment without relapse. This association has not been described previously and may be added to the list of extrahepatic immune-mediated conditions associated with primary biliary cirrhosis.

[Acute respiratory insufficiency caused by diffuse pulmonary hemorrhage].

Two cases of adult respiratory distress syndrome due to diffuse pulmonary haemorrhage are reported. The first patient was treated with azathioprine, prednisolone, cyclosporine and ranitidine for haemorrhagic rectocolitis; the second has untreated primary biliary cirrhosis. Haemoptysis only occurred in the latter. Both had severe isolated hypoxaemia. Chest X-rays revealed bilateral alveolar infiltrates. Bronchoscopies showed a diffusely bleeding bronchial tree. Both patients recovered after having been mechanically ventilated with positive end-expiratory pressure for six and eight days respectively. The cause of the diffuse pulmonary haemorrhage was, in the first case, severe thrombocytopaenia (17,000 G.1-1) of central origin, and, in the other patient, an unspecified vasculitis. Diffuse pulmonary haemorrhage should be added to the list of possible causes of the adult respiratory distress syndrome.

[Biological and clinical surveillance techniques: problems and complications of enteral feeding].

The present high degree of safety of enteral nutrition is due to improvements in commercial nutritional products and, chiefly, to the respect of well-established rules of administration. Monitoring the equipment consists of making sure, by means of repeated rinsing, that the fine digestive tract prosthesis remains patent. Nutrients are now sterile and easy to use, and their compositions varied and well-balanced. They are very well tolerated in most cases. Monitoring the speed of gastrointestinal (GI) transit is crucial. One must watch for the occurrence of multiple daily stools, due to the speed of administration or to malabsorption, proliferation of exogenous or endogenous pathogens or patient's underlying pathology, and for a gastric fluid residual volume exceeding 150 ml. Regular controls of gastric emptying and of GI prosthesis position prevent the very rare complications that are aspiration pneumonia and unexplained chronic dyspnoea. Possible interference between enteral nutrition and patient's pathology or treatment must be detected and prevented.

[Value of an imipenem-cilastatin combination in surgery and surgical care units].

One-hundred and ninety-nine patients with severe infection caused by susceptible organisms were treated with imipenem-cilastatin administered intravenously in doses of 31 mg/kg/day on average. The drug was given alone in 71 per cent of the cases and with another antibiotic (usually an aminoglycoside) in 13 per cent. In 57.4 per cent of the patients several micro-organisms were involved. Clinical success was achieved in 169 patients (84.9 per cent), 129 of whom (64.8 per cent) were cured and 40 (20.1 per cent) were improved. Failure was observed in 30 patients (15.0 per cent). Fifteen patients died during treatment; death was directly related to the infection in 5 and occurred while the infection had clinically regressed in 5; in the remaining 5 patients persistence of the infection played a determinant role in the fatal outcome. In 15 patients the lack of clinical improvement under imipenem-cilastatin required by 5/65 Pseudomonas strains and 2/56 Anaerobes strains initially isolated, or to superinfection, or to persistence of the initial strain in the focus of infection. Treatment was discontinued in 8 cases due to adverse events (skin intolerance 4, thrombocytopenia 4). There was no statistically significant difference in the outcome of patients treated with imipenem-cilastatin alone or combined with another antibiotic.

[Sleep and psychological disorders in intensive care units].

The evaluation of sleeping and psychical disorders for 24 patients hospitalized during at least 5 days in an intensive care unit was realized through a semi-guiding talk with a psychiatrist. All patients were faced to a very disordered sleep and a high number of psychopathological phenomenons: amnesia, disorientation, hallucinations, anxiety, depression. Different factors are concerned in the genesis of those troubles. Some means could prevent it.

Regulation of ketone body flux in septic patients.

To assess the effect of sepsis on ketone body (KB) kinetics in humans, we measured in normal and septic subjects KB appearance rate (Ra) before (initial state) and during a rise of free fatty acids (FFA) level (intravenous infusion of a triglycerides emulsion). We studied normal subjects in postabsorptive state and septic patients when receiving an hypocaloric intravenous infusion of glucose and amino acids or 12 h after its interruption. When receiving glucose and amino acids infusion, septic patients had higher glucose and insulin levels than normal subjects, and despite lower FFA concentrations (255 +/- 44 vs. 480 +/- 51 mumol/l, P less than 0.05) comparable initial KB Ra (2.50 +/- 0.10 vs. 2.48 +/- 0.30 mumol.kg-1.min-1). Triglyceride infusion increased FFA to comparable values (septic 780 +/- 130, normal 730 +/- 45 mumol/l), but KB Ra rose in septic patients only to 3.7 +/- 1.1 instead of 7.7 +/- 1.1 mumol.kg-1.min-1 as in normal subjects (P less than 0.05). Somatostatin infusion decreased the hyperinsulinemia of septic patients but did not restore a normal ketogenesis. After interruption of nutriment infusion, septic patients had normal FFA levels and only mild hyperglycemia and hyperinsulinemia. Their initial KB Ra was not modified. However, their response of KB Ra (increase to 6.27 +/- 2.0 mumol.kg-1.min-1) to raised FFA levels (842 +/- 170 mumol/l) was comparable to the response of normal subjects. In conclusion, although septic patients receiving an hypocaloric parenteral nutrition had a depressed ketogenesis they were able to restore a normal ketogenic capacity after a short-time caloric deprivation. Glucose and/or insulin appears to have a major role in this modulation of hepatic ketogenesis.

[Fulminant and subfulminant hepatitis treated by orthotopic transplantation of the liver. Apropos of 10 cases].

In the period between 15/12/1987 and 15/08/1989, ten patients with either fulminating or subfulminating hepatitis have been treated by orthotopic liver transplantation (O.L.T.). Six patients are doing well in the post-operative period with a mean follow-up of 12 months (7-23 months). No evidence of neurological sequelae has been observed and recurrence of HB virus infection was absent from the three cases who survived hepatitis B transplantation. Four out these ten patients died after initial successful O.L.T... One patient succumbed 7 days after O.L.T. from sepsis or early super-acute rejection, the second 21 days after O.L.T. from neuromeningeal listeria, the third 43 days post O.L.T. from acute rejection, while the fourth developed cytomegalovirus pneumonia and died 61 days after O.L.T. Orthotopic liver transplantation has become the treatment of fulminating hepatitis. It is an emergency which is usually accompanied by successive difficulties in decision making: indication criteria, then acceptance or refusal of ABO incompatible grafts (5/10) and of suboptimal donors. Orthotopic liver transplantation for fulminating hepatitis is technically easy to perform, but usually requires the use of extra-corporal veno-venous circulation. Accompanying intensive medical care is essential and usually includes one or multiple plasmaphereses to correct existing coagulopathy without any fluid or sodium overload to the circulation.

Nitrogen-sparing effect of epidural administration of local anesthetics in colon surgery.

A nitrogen-sparing effect of epidural anesthesia has been clearly demonstrated in gynecological and lower abdominal surgery. To determine if epidural anesthesia also has a protein-sparing effect during major upper or mid-abdominal surgery, postoperative nitrogen balance and 3-methylhistidine urinary excretion (an index of skeletal muscle protein catabolism) were measured for 6 days in 28 patients who had undergone colon resection for cancer with general anesthesia (N2O-O2-1% enflurane) either supplemented with low dose fentanyl plus intermittent systemic pentazocine for postoperative pain (n = 13), or the same general anesthetic plus epidural injection of either etidocaine 1% intraoperatively and bupivacaine 0.25% postoperatively (n = 8) or meperidine (n = 7) for 48 hr after skin incision. The cumulative 6-day nitrogen balance and the cumulative 3-methylhistidine urinary excretion were significantly less after epidural injection of etidocaine intraoperatively and bupivacaine postoperatively than in the two other groups. There was a significant correlation between the daily urinary excretion of 3-methylhistidine and the daily nitrogen balance in the three groups. This study suggests that in colon surgery, epidural analgesia with local anesthetics in the postoperative period improves nitrogen balance and this effect takes place partly in the muscle.

[Home parenteral nutrition for adults. Results of a multicenter survey in France].

Home parenteral nutrition (HPN) is a growing therapy in North America and Europe. This first multicenter retrospective study of HPN in France has collected data on 81 patients sent home before December 31st, 1985. Intestinal failure, secondary to short bowel syndrome, small bowel stenosis or fistula, was the main indication for HPN. In 95 p. 100 of the cases, the clinical nutritional status during HPN was either normal or subnormal. The annual incidence of catheter change for technical complication was 0.78 and the mortality rate was 1.2 p. 100. Social rehabilitation was recovered during HPN in 60 p. 100 of patients. Thirty percent of the patients died of their primary disease during HPN but 43 p. 100 were off treatment, and 27 p. 100 were on HPN at the end of the study. The cost of HPN was reduced by 64 p. 100 in comparison with the cost of parenteral nutrition carried out in hospital.

[Pharmacokinetic study of pefloxacin in 37 hospital patients under resuscitation].

Pharmacokinetics of pefloxacin were studied in thirty-seven intensive care patients. Fluorimetric assay was used for determining pefloxacin concentrations. Serum concentrations were usually far above threshold levels; however, wide variations across patients were evidenced, with no demonstrable relation to physiologic status. For this reason, pefloxacin assay is useful in high risk patients to avoid subconcentrations.

Clinical study of muzolimine in acute renal failure, pharmacodynamics and pharmacokinetics.

UNLABELLED: The aim of this study was to test the efficiency of muzolimine in patients with acute renal failure (ARF). METHODS: 6 patients, all males, 46 to 78 years old (mean 67.3 +/- 12.5) suffering from acute renal failure as a complication of a surgical procedure (4 cases) or a medical disease (2 cases) were selected. Creatinine clearance rates were below 20 ml/min for all subjects except one (mean: 14.4 ml/min range 4-34), blood urea levels from 21 to 65 mmol/l (mean = 36.4); mean urinary output, during the 24 hours preceding the study (D-1) was 100.4 +/- 57 ml/h (range 36-208) without any diuretic treatment. No patient was on dialysis. On the treatment day a single oral dose of muzolimine (240 mg) was administered in the morning. During the treatment day (D0) and the post treatment day (D + 1), pharmacodynamics and pharmacokinetics were evaluated. Mean urinary output increased from 1.67 +/- 0.95 ml/min, at D-1 to 3.24 +/- 2 ml/min at D0 (NS), with great differences between patients. The main effect was noted between 0 and 6 hours after the ingestion of muzolimine. The mean electrolyte output increased from D0 to D1 for Na+ (0.1 mmol/min +/- 0.08----0.25 +/- 0.1-NS), K+ (0.05 mmol/min +/- 0.02----0.08 +/- 0.07-NS), Cl- (0.07 +/- 0.07 mmol/min----0.30 +/- 0.12 p less than 0.05) and Ca++ (1.89 +/- 1.89 meq/24 h----4.1 +/- 2 NS), with large individual variations. Mean urea output increased slightly in only 3 patients.(ABSTRACT TRUNCATED AT 250 WORDS)
