Bacterial translocation is defined as the passage of viable bacteria from the gastrointestinal tract to extraintestinal sites, such as the mesenteric lymph node complex, liver, spleen, kidney, and blood. The major mechanisms promoting bacterial translocation in animal models are: (a) disruption of the ecologic equilibrium to allow intestinal bacterial overgrowth, (b) deficiencies in host immune defenses, and (c) increased permeability of the intestinal mucosal barrier. These mechanisms can act in concert to promote synergistically the systemic spread of indigenous translocating bacteria to cause lethal sepsis. Studies are presented of attempts to delineate the mechanisms promoting bacterial translocation utilizing animal models of intestinal bacterial overgrowth, immunosuppression, T-cell deficiencies, solid tumors, leukemia, diabetes, endotoxemia, hemorrhagic shock, thermal injury, bowel obstruction, bile duct ligation, protein malnutrition and parenteral nutrition. Also described are the use of selective antibiotic decontamination or nonspecific macrophage immunomodulators in attempts to reduce bacterial translocation from the gastrointestinal tract.

Five years of experience gained with the CryoCare Extremity Stabilization System (CESS) were evaluated in this study. Twenty-one patients underwent freezing amputation. Five patients died before undergoing surgical amputation. Symptomatic relief, control of odor, decreased demand on nursing staff, and appreciation of the family make this approach valuable even when long-term survival is not anticipated. Ten patients who underwent freezing amputation subsequently underwent surgical amputation and were discharged. Six patients underwent freezing and surgical amputation but died prior to discharge. The patients selected for the freezer application were deemed to be prohibitive operative risks because they were experiencing systemic toxicity from their ischemic limb and underlying diseases. Six patients demonstrated myoglobinuria prior to freezing which cleared with CESS. The physiologic amputation allowed stabilization of medical problems including cardiac arrhythmias, congestive heart failure, sepsis, renal failure, diabetes, and respiratory failure. Freezing of an ischemic extremity allows delay in amputation enabling physicians to achieve maximal medical stabilization. It permits symptomatic relief in patients whose long-term survival is not anticipated. Physiologic freezing amputation should be included in the repertoire of all surgeons.

A case of emphysematous pyelonephritis with disseminated intravascular coagulation (DIC) is presented. A 54-year-old woman was admitted to our hospital because of unclear consciousness and extremely high blood glucose level. The laboratory data suggested uncontrolled diabetes mellitus (DM) and urinary tract infection with sepsis and DIC. The plain abdominal X-P and abdominal CT revealed the existence of gas in the right renal parenchyma, perinephric tissue and the upper part of the right ureter. Right nephrectomy was performed after the improvement of the patient's condition by the echo-guided drainage of the right kidney and the treatment for infection, DM and DIC. We reviewed 71 cases of emphysematous pyelonephritis in the Japanese literature and the choice of treatment was discussed.

The relationship between outcome and hemoglobin (Hgb), oxygen extraction ratio (ER), history of cardiac, renal, pulmonary, and/or hepatic disease, diabetes, malignancy, sepsis, hypertension, and active bleeding was analyzed in 47 patients with severe anemia (Hgb less than 7.0 gm/dl, mean = 4.6 +/- .2 gm/dl) to evaluate the effect of Hgb on survival and to look for other predictors of outcome. All patients had refused blood transfusion on religious grounds and were participants in a randomized, controlled study of the blood substitute Fluosol DA-20 per cent. Patients were analyzed as a group and after stratifying by Hgb into four levels: (Hgb less than 3.0 gm/dl, N = 7; Hgb less than 3.5 gm/dl, N = 12; Hgb less than 4.0 gm/dl, N = 17; Hgb less than 4.5 gm/dl, N = 23) and by ER into two levels of less than 50 per cent and greater than 50 per cent. Only Hgb, ER, sepsis and active bleeding were predictors of outcome, with sepsis being the only significant, independent predictor of outcome at all levels (P less than .01). Active bleeding was a predictor for levels of Hgb below 4.0 gm/dl. Hgb level alone was a significant predictor only at levels below 3 gm/dl (P less than .05). Extraction ratio interacted with Hgb only below 3 gm/dl (P less than .05). Multiple independent factors influence outcome in the severely anemic patient, the strongest being sepsis and active bleeding. Prevention of sepsis and early intervention to stop bleeding should improve survival in the patient who refuses transfusion.

Between January 1982 and August 1989, cadaveric renal transplantation was performed in 22 patients 65 years old or older. Mean recipient age was 68 years (range 65 to 73 years). There were 17 men and 5 women. Additional risk factors included retransplantation (3 patients), high (greater than 30%) panel reactive antibody (4) and diabetes (1). All patients received cyclosporine as part of the immunosuppressive regimen. The 3-year actuarial patient and allograft survival rates were 89% and 71%, respectively. There were 6 graft losses due to chronic rejection (2 patients), renal vein thrombosis (1), myocardial infarction (1), withdrawal of immunosuppression because of sepsis (1) and primary nonfunction (1). Of the 16 patients with a functioning graft 12 currently have a serum creatinine of less than 2.0 mg./dl. These results suggest that cadaveric renal transplantation is an acceptable form of treatment for patients older than 65 years with end stage renal disease.

Diabetes mellitus associated with urinary tract infections and ureteral obstruction can be predisposing factors leading to emphysematous pyelonephritis. Fever, flank pains, and a palpable renal mass, associated with dehydration and hyperglycemia, were the most frequent presenting symptoms associated with emphysematous pyelonephritis. Computerized tomography (CT) scan is the best method to identify a renal or perirenal abscess and its ramifications. Intravenous antibiotic therapy is determined by blood and urine cultures. Mortality was zero in patients treated by nephrectomy. One patient who had incision and drainage of a renal abscess died of sepsis, and 1 patient died of sepsis following incision and drainage of a prostatic abscess. Patients with cystitis emphysematosa require antibiotic therapy and relief of bladder outlet obstruction. Prostatic abscess is best treated by perineal incision and drainage. Periurethral scrotal abscesses should be incised, drained, and the overlying necrotic skin debrided. Early diagnosis and aggressive medical and surgical management of gas-forming infections of the genitourinary tract are vital.

Patients with dysgenetic gonads and Turner syndrome are unlikely to develop endometrial carcinoma unless they have received unopposed estrogen replacement therapy. This case describes a 54-year-old woman with Turner syndrome and primary amenorrhea who developed adenocarcinoma of the endometrium without having received hormone replacement. Vaginal bleeding, a pelvic mass, and sepsis were the presenting symptoms. The patient also had diabetes mellitus and hypothyroidism. Polyglandular endocrine patterns are known to occur with a high frequency in these patients. The woman's chromosome studies revealed a modified 46,X,i(Xq) (isochromosome X). This is the first report of an isochromosome X patient to develop endometrial cancer without receiving estrogen replacement. The etiology of this rare case may be an increased propensity for patients with X-chromosome deletions to develop neoplasms in general, or extragonadal estrogen production.

To assess the mechanism of insulin resistance in sepsis, we investigated insulin receptor binding and glucose uptake in isolated rat epididymal adipocytes. Male Sprague-Dawley (SD) rats weighing 200-220 g were submitted to cecal ligation under chloral hydrate anesthesia, followed by double punctures with 18-G needle into the ligated portion to produce peritonitis. Age-matched SD rats without operation were used as the controls. After starvation for 16 h, blood samples were taken from the inferior vena cava for bacterial culture and assayed for plasma glucose and IRI levels, and then adipocytes were isolated from the dissected epididymal fat tissues. Plasma levels of both glucose and IRI in septic rats were higher than those in the controls. The [125I]-insulin binding rate of the adipocytes in septic rats was similar to that of the controls. However, [3H]-2-deoxy-D-glucose uptake by adipocytes was markedly decreased in the septic group (approximately 45% of the control group at the plateau). In conclusion, this study suggests that insulin resistance in the septic state results, at least partly, from impairment in the post-binding level of the insulin receptor.

The present study was undertaken to identify the preventable factors operative in high fetal and neonatal losses. Over a period of one year, of total of 1,600 consecutive deliveries, 1,107 were considered to be at-risk: there were 33 fetal and 31 early neonatal deaths with an overall perinatal mortality rate of 40/1,000 births. Perinatal mortality was higher in mothers who had received inadequate antenatal care and/or with bad obstetric history. Major maternal and obstetric factors associated with a high PMR were: advancing maternal age and parity, antepartum hemorrhage, diabetes, anemia, instrument and vaginal breech delivery. Overall cesarean section rate was 16.9%. Infants with a gestational age of less than 37 weeks and/or of birth weight of less than 2,500 g contributed for 56.2% and 68.7% of the total perinatal losses respectively. PMR was three fold higher among twins compared with singleton births. Identifiable causes of perinatal deaths observed were: asphyxia (31%), congenital anomalies (18.7%), sepsis (18.7%) and low birth weight (25%). It would appear that preventable factors are operative in over two third of the cases of perinatal loss and better maternal health, obstetric and neonatal care can improve the perinatal outcome in majority of the cases.

A man aged 46 years with diabetes mellitus was admitted with acute right-sided renal symptoms. Pyelonephritis emphysematous without concretions was found. The patient was treated with insulin, fluids, electrolytes and antibiotics and nephrostomy was performed and, subsequently, an internal JJ-catheter in the ureter. The symptoms disappeared and he was discharged on a low dosage of sulphamethizol. After the planned removal of the JJ-catheter, sepsis running a lethal course developed. This emphasizes the importance of adequate prophylactic antibiotic therapy in connection with interventions in the urinary tracts.
