Twenty nine patients of an intensive care unit (9 women and 20 men), aged 63.9 +/- 15.8 years, with a mean body weight of 62.5 +/- 11.8 kg were treated during 9.4 +/- 2.1 days by aztreonam (2 x 1 g/24 h) administered by short infusion (30 min) for a severe infection due to a Gram-negative bacilli. The primary (n = 25) or nosocomial (n = 4) infection sites were a peritonitis (14), a septicaemia (6), a cholecystitis (6), a pyelonephritis (5), a cholangitis (2), a subphrenic abscess (1) or a pneumonia (2). The isolated Gram-negative bacilli were all susceptible to aztreonam, their MIC being less than or equal to 0.5 micrograms/ml, except for a Pseudomonas aeruginosa (MIC = 4 micrograms/ml). Aztreonam was administered as a single therapy to 7 patients and in association with metronidazole (18) and/or penicillin G (14) to 22 patients; in fact, anaerobes were isolated in ten patients. The mean serum concentrations of aztreonam, as measured by HPLC, before and after the 7th administration respectively were 83.2 +/- 17.5 and 6.1 +/- 5.5 micrograms/ml for peak and through levels. The treatment of the 29 infections was a success in all the cases. No complication occurred due to the presence of Gram positive cocci (n = 4) in the first bacteriological sample, or due to the emergence (n = 12) of Gram positive cocci, except for one case of sepsis of the abdominal wall by Staphylococcus aureus. Aztreonam (2 x 1 g/24 h) may be a suitable alternative for the treatment of severe infections of intensive care units, mostly due to Gram-negative bacilli.

At our hospital, 47 out of 184 consecutive splenectomies performed over 7 recent years were carried out on patients afflicted with various hematologic diseases. The results of these 47 splenectomies were the subject of a careful retrospective analysis. The majority of the splenectomies (81%) were therapeutic. Cytopenia, particularly thrombocytopenia, was the most common indication for surgery. As a whole, good therapeutic responses with rapid improvements in peripheral blood picture and/or diminished symptoms of pressure discomfort from an enlarged spleen were obtained. There was no peri- or postoperative mortality; 23% major and 26% minor postoperative complications were recorded. In patients with perioperative bleeding and various postoperative complications, the spleens were larger than in subjects who run an uneventful peri- and postoperative course. During the follow-up period, 4 septicemias occurred in 3 patients. In 2 of these patients, the septicemias coincided with a cholecystitis and a pneumonia, respectively. None of the infections was lethal. It is concluded that elective splenectomy for hematologic disease in well selected and carefully prepared patients is beneficial and can be performed without mortality or major hazards.

A homosexual youth presented with undiagnosed acute cryptosporidial cholecystitis, a fever of 102.8 degrees F and a WBC of 3500/mm3. This was preceded by several months of watery diarrhea and 20% weight loss. Following cholecystectomy, G-I function was maintained by efficient esophageal aspiration of swallowed air, with simultaneous immediate duodenal feeding of elemental diet. He absorbed 160 g amino acids and 4200 kcal, and was safely self-sufficient when discharged 26 hours postoperatively. Reappearance of the persistent cryptosporidial enteritis was followed by diagnoses of the offending organism and the associated AIDS. He failed to respond to specific spiramycin therapy, and 8 months after cholecystectomy he succumbed to pneumocystis carinii pneumonia. For this malnourished and particularly vulnerable patient, preservation of postoperative G-I function and its exploitation for enteral support may have been essential to enhance "immune competence" and lead to a remarkably smooth and rapid recovery.

Sepsis is a significant cause of late morbidity and mortality in the severely injured patient. In addition to the risk factors of shock, multiple transfusions, and contamination, the trauma patient may have the additional factor of severe immunologic depression. The prevention of sepsis should be an early consideration. Invasive diagnostic and therapeutic maneuvers should be limited to those that are absolutely necessary, since the incidence of nosocomial infection is high. Prophylactic antibiotics should not be misused, as these may increase the risk of serious, resistant infections. Frequent examination of sputum smears may allow the early diagnosis of pneumonia. Nutritional supplementation can improve host defenses, and should be instituted early. The patient in septic shock should be resuscitated and stabilized in the intensive care unit. Monitoring should include determination of cardiac index and systemic oxygen consumption. Computed tomography has emerged as the primary modality for the diagnosis of intra-abdominal sepsis. When combined with percutaneous drainage of abscesses, it represents a rapid and safe approach to the diagnosis and treatment of the critically ill septic patient. In certain cases, such as bowel perforation or necrosis, anastomotic breakdown, or acalculous cholecystitis, laparotomy is the procedure of choice. Opportunistic infections may become significant in patients who have required a prolonged course of treatment. In the patient with multiple organ-system failure who is not responding to therapy and in whom no clear source of sepsis has been identified, exploratory laparotomy should be considered. Antibiotics should be used with caution and should not started in every patient with a fever. Their use should be directed by appropriate cultures and sensitivities.(ABSTRACT TRUNCATED AT 250 WORDS)

To assess the role of the general surgeon in the care of patients with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC) the hospital records of all patients with AIDS or ARC who underwent a major operation at the General Surgical Service of Crawford W. Long Memorial Hospital were reviewed. Of 79 patients with AIDS or ARC diagnosed since 1982, 14 required major abdominal surgery. Operations performed were for gastrointestinal (GI) complications of opportunistic infections and neoplasms (four), diagnosis of major retroperitoneal lymphadenopathy (four), and treatment of AIDS-related immune thrombocytopenia (six). GI complications consisted of two cases of cytomegalovirus perforation of ileum and colon, one case of bleeding ileocolonic lymphoma, and one case of cryptosporidium cholecystitis. Laparotomy for diagnosis of retroperitoneal lymphadenopathy was performed in four patients and provided diagnostic material in three of them. Six patients underwent splenectomy for AIDS-related immune thrombocytopenia. Four of these patients had previously been treated with prednisone without impressive results. All patients had marked improvement of their platelet counts and clinical bleeding after splenectomy. Postoperative complications were common and consisted of wound infection, disseminated intravascular coagulation, GI bleeding, pneumocystis pneumonia, small-bowel obstruction, and cytomegalovirus pneumonia. One patient died after laparotomy for perforated ulcers of the ileum and colon.

We reviewed the hospital admissions of 168 patients with acute leukemia to determine the incidence of persistent fever following recovery from chemotherapy-induced granulocytopenia. This phenomenon was observed during 26 (15.5%) hospital admissions. The microbiologically and/or clinically documented causes identified in 23 instances included viral infection (two patients), perirectal abscess (two patients), Hickman catheter-related bacteremia (two patients), intraabdominal infection (four patients), and nine fungal infections (five resolving pneumonia, one disseminated candidiasis, three focal hepatic and/or splenic mycosis). One patient had both cholecystitis and a pneumonia of uncertain origin and three patients had drug reactions. Although overall the source of fever was usually readily apparent, focal hepatic and/or splenic mycosis produced protracted fevers that were difficult to diagnose. Visceral fungal infection should be a leading diagnostic consideration in patients with leukemia who remain persistently febrile following recovery from chemotherapy-induced granulocytopenia.

In a five-year period, 29 cases of bacteremia and/or meningitis in adults caused by Haemophilus influenzae were seen in our large community hospital. There were 17 cases of bacteremic pneumonia and 12 cases of serious extrapulmonary infections. The extrapulmonary infections included cases of endocarditis, meningitis, cholecystitis, epiglottitis, tubo-ovarian abscess, and cellulitis. In contrast with the pediatric experience, H influenzae type B was the causative pathogen in only 45% of patients and only one isolate was ampicillin resistant.

Ten critically ill patients presenting with nosocomial infection caused by Serratia marcescens (SM) not responding to prior chemotherapy were treated in an open study with Moxalactam (MOX) alone [6] or in combination with an aminoglycoside [4]. In initial disc diffusion tests, all isolates of SM were highly susceptible to MOX. Clinically, three patients were cured and four improved. Three patients died: one from SM pneumonia, one from gangrenous cholecystitis and another from ARDS. Bacteriologically, SM were eliminated from blood cultures in all seven patients with septicemia but were recovered post mortem from the lung of one patient. In three cases with localized infection, SM were eliminated once and persisted twice. Selection of resistant SM was observed in three patients but became clinically relevant in one case only. Resistant SM strains also showed reduced susceptibility to other cephalosporins and aminoglycosides. Emergence of enterococci occurred four times, in two cases with clinical consequences. MOX is a useful drug for the treatment of SM infections, but a definite risk of selecting multiresistant SM strains and of enterococcal overgrowth must be kept in mind.

A new human gamma-globulin for intravenous use, SM-4300, was administered to 13 patients with infectious diseases. Five grams of SM-4300 was drip infused to each patient whose infection was not controlled by previous administered antibiotics. All of 13 patients had primary diseases besides infections. Thirteen patients were composed of 4 with pyelonephritis, 2 with pneumonia, 1 with bronchopneumonia, 1 with bronchitis, 1 with pyothorax, 2 with sepsis and 2 with cholecystitis. The results obtained were good in 3 cases, fair in 2 cases and poor in 7 cases. The results of a patient was not determined. No side effect was found including in laboratory findings.

Use of SM-4300, which is a newly developed human immunoglobulin preparation for intravenous administration, has clinically been evaluated in the patients with severe or intractable bacterial infections. Of total 13 cases of the admitted patients at the 1st department of internal medicine, faculty of medicine, Kyushu university, 10-pneumonia case were associated with blood diseases like acute myelocytic leukemia (AML) and multiple myeloma (MM), and in addition, with other underlying diseases like lung cancer and bronchiectasis, 1 was prosthetic valve endocarditis, 1 cholecystitis associated with pericarditis and 1 fever of undetermined origin (FUO). SM-4300 of 5 g single bolus or 3 daily doses of 2.5 g per day were infused with chemotherapy drugs preceedingly administered for more than 3 days and the results were evaluated; good in 4, fair 4, poor 2 and unknown 3, and the efficacy rate was 40%. Bacteriologically, the results were decreased in 1, persisted 1 and the majority was unknown. Observed were no side reactions nor the changes in clinical examination variables incurred by this drug. It is therefore considered that SM-4300 is of use for the treatment of intractable bacterial infections when used with antibiotics.
