The clinical findings, pathologic features, and outcome were investigated in 46 patients in whom Torulopsis glabrata was isolated in 131 specimens of blood. Nineteen of the patients had only a single positive blood culture and no evidence of systemic yeast infection, while 27 patients had a clinically significant fungemia based upon the occurrence of 2 or more positive blood cultures, or the combination of a positive blood culture and isolation of the organism from a closed body cavity or demonstration of the yeast in tissue sections. The predisposing factors to the development of fungemia included the presence of intravenous lines, indwelling Foley catheters, antibiotics and surgery, especially when the gastrointestinal tract was involved. Only 22% of patients received either steroids or cytostatic agents. Possible portals of entry were suggested by the prior isolation of the organism from urine, sputum, wounds, and central venous catheter tips in most of the patients. Twelve of 27 patients with clinically significant fungemia were treated. The initial mode of therapy in nine patients was removal of intravenous lines because of the clinical suspicion of catheter related sepsis. Seven of the patients improved rapidly and one more after amphotericin B was subsequently administered. Amphotericin B was the initial therapy in three cases. One patient was cured while another died of an unrelated infection. Five patients were not treated although the isolation of T. glabrata had been reported; the fact that the presence of the organism was felt to be unimportant was considered to be a factor in the delay of treatment. In the remaining 10 patients the organism was isolated only after the patient had died. Division of the patients into four groups based upon whether the individuals survived, died of unrelated disease, died with potentially lethal infection, or died with T. glabrata infection significantly contributing to death, revealed a spectrum of disease, certain signs of which appeared to be of predictive value as prognostic indices of survival and severity of the infection. Seven patients with transient fungemia experienced an acute episode of high spiking fever (greater than 102.5 degrees F), rigors and/or hypotension, six of whom improved after the intravenous catheter was removed, suggesting a catheter-related sepsis. In contrast, persistent low grade fever (less than 102.5 degrees F) characterized eight of the nine patients in whom T. glabrata infection was considered either potentially lethal, or contributing significantly to death. A deteriorating clinical course with organ failure was also associated with this latter category of patients. Catheter-induced specticemia was considered in only two patients in this category. The autopsy and clinical findings in this investigation as well as reported experimental studies suggest that T. glabrata is an organism of low virulence. The patients' underlying disease (e.g., neoplasia) and coexisting bacterial infection are the most important factors responsible for death.

The bile is infected in 31% of patients undergoing an operation for biliary disease and these patients have a significantly greater risk of developing wound sepsis and septicaemia than patients with sterile bile. Prophylactic antibiotics which achieve satisfactory serum rather than high bile levels have been shown to reduce the morbidity of biliary operation. However, only patients with infected bile benefit from prophylactic chemotherapy. Patients with infected bile can be satisfactorily identified by preoperative duodenal aspiration, operative Gram staining of bile, or clinical presentation. The high-risk patients requiring preoperative antibiotic cover include anyone over 70 years of age, jaundiced patients, those requiring emergency operation, patients with recent rigors, anyone having had previous biliary operations, and patients known to have choledocholithiasis.

Septicemia is a rare complication of platelet transfusion. A case is reported of transfusion-associated septicemia in a 66-year-old man who received a 10-unit pool of platelets. During transfusion, he experienced rigors, wheezing, dyspnea, and fever. A total of four blood cultures drawn 10 and 36 hours after discontinuation of the transfusion grew Staphylococcus epidermidis. Culture of the residual platelet pool yielded S. epidermidis with a colony count of 10(5) organisms per mL. Strain identity of all four blood isolates and the platelet pool isolate was confirmed by gel electrophoresis of EcoRI and HindIII restriction digests of whole-cell DNA. There have been 31 prior reported cases of platelet transfusion-associated septicemia, of which 9 have been caused by coagulase-negative staphylococci. Systemic reactions to platelet transfusions should prompt consideration of transfusion-associated bacteremia as the cause.

283 records of all Wellington, New Zealand, Hospital patients categorized as having had a septic abortion from 1960 to 1979 were retrieved and reviewed; 7 records could not be found. Morbidity was assessed by duration of hospital stay and the incidence of complications. Septicemia was defined by a positive blood culture rigors. Hypotension was assumed to be due to hemorrhage unless endotoxic shock was positively identified. Significant hemorrhage was also diagnosed if a blood transfusion was required. The annual number of admissions for septic abortion over the 20-year period decreased substantially: 203 cases from 1960 to 1969 and 80 cases from 1970 to 1979. The total number of abortion admissions of all types also decreased over the same period. During this period the total number of births in Wellington public hospitals initially increased and then declined, suggesting some degree of independence between total abortions and birthrate. The peak of total abortions in 1978-79 represents the initial increase in hospital therapeutic abortions under the Contraception, Sterilization and Abortion Act 1977. The gestational age at the time of septic abortion ranged from 7 to 26 weeks. The mean gestation by year ranged from 8.6 to 15 weeks. No trend was obvious. The mean duration of hospital stay declined, e.g., 7.3, 7.6, 6.0, and 5.3 days in successive 5-year periods. Morbidity was greater during the 1st decade but there were 2 patients who in 1974 and 1975 stayed 23 and 28 days, respectively. Septicemia patients numbered 39 (35%) in the first 5 years, and fell successively to 31 (33%), 17 (36%), and 6 (17%) in each succeeding 5-year period. A similar trend was noted for significant hemorrhage: 38 (34.5%), 39 (42%), 13 (28%), and 3 (8.5%) between 1975 and 1979. Only maternal death due to septic abortion occurred in 1960. The patient was noted to be fairly "feebl minded" and the diagnosis was delayed because she hid her symptoms. She went into acute renal failure, fitted, then collapsed and died quite suddenly. The Wellington admissions for septic abortion represented 1 in 16 of the New Zealand total in 1965 and 1 in 28 in 1979. It would seem that the trend of decreased septic abortion admissions in Wellington is a mirror of the national trend.

Lemierre syndrome, also known as postanginal sepsis, is an illness characterized by the development of a fusobacterial septicaemia with multiple metastatic foci following an attack of acute tonsillitis. It typically affects previously healthy adolescents and young adults who, following an attack of sore throat, become acutely ill with hyperpyrexia, rigors and multiple metastatic abscesses. The clinical picture tends to vary widely because of the possible involvement of a number of body systems and organs in the disease process. This serious complication of oropharyngeal sepsis had a mortality rate in excess of 90 per cent in the pre-antibiotic era. Although now rarely seen and often forgotten, it remains a potentially life-threatening condition. We present four cases of post-tonsillitis fusobacterial septicaemia to illustrate the variability of the clinical presentation and stormy clinical course frequently associated with this rare syndrome.

Struvite renal stones are caused by infection of the urine with bacteria that synthesize the enzyme urease. Ammonium is released by the breakdown of urea by urease, the urine becomes highly alkaline, and magnesium ammonium phosphate (struvite) and carbonate apatite crystallize. Incorporation of the infecting bacteria within the developing stone, results in a focus of infection that is resistant to conventional antimicrobial therapy, and which is manifested clinically by repeated urinary tract infection caused by persistent bacteriuria. Extracorporeal shock wave lithotripsy (ESWL) currently is accepted as the election treatment for most renal calculi. This trial examines the bacteriologic aspects pre and post-ESWL. Eighty adult patients, 47 females and 33 males, without clinical signs of urinary tract infections (UTI) were submitted to urine cultures pre and post-ESWL. The first 50 patients underwent during and post-ESWL, 150 blood cultures, which all proved to be negative, confirming very low risk of generalized sepsis. No patient presented fever, chills or rigors pre or postprocedures. With respect to urine cultures 43 patients (52.5%) had a pre-ESWL UTI, in comparison to 49 (60%) who had a UTI post-ESWL. The distribution of organisms pre and post-ESWL was as follows: Proteus mirabilis (22/22), Escherichia coli (11/11), Pseudomonas aeruginosa (4/5), Klebsiella pneumoniae (2/2), Enterobacter cloacae (0/1), Alcaligenes odorans (1/2) Enterococcus faecalis (1/3), Staphylococcus saprophyticus (1/2) and Candida albicans (1/1). In this study 6 patients presented bacteriuria post-ESWL probably due to bacteria from inside the calculi. According to these results, the risk of bacteremia seems to be very low. In 60% of staghorn renal stones we could demonstrate a bacterial infection.

Twenty-seven cases of ascaris cholecystitis and cholangitis were managed in a surgical unit of a general hospital in Yangon, Myanmar, from January 1989 to March 1990. Nineteen women and eight men with a mean age of 42 years were studied. Main clinical manifestations were right hypochondrial pain, fever, chills, rigors, nausea, vomiting and jaundice. Diagnosis was established by abdominal ultrasonograms in all cases. Laparotomy was performed in all cases because of failure to respond to initial conservative treatment. Live and dead ascarids were found in the gall bladder and biliary ductal system. Cholecystectomy, bile duct exploration, worm extraction and T-tube drainage were done in all cases. There were no deaths. Two patients developed minor wound sepsis. During the follow-up period ranging from 3 to 12 months, there was no recurrence of symptoms in all patients. All patients were given antihelminthics before discharge and three weeks later.

As procalcitonin concentrations have been shown to be elevated in patients with septicemia and gram-negative infections in particular, we proceeded to investigate the effect of endotoxin, a product of gram-negative bacteria, on procalcitonin concentrations in normal human volunteers. Endotoxin from Escherichia coli 0113:H10:k, was injected i.v. at a dose of 4 mg/kg BW into these healthy volunteers. Blood samples were obtained before and 1, 2, 4, 6, 8, and 24 h after injection of the endotoxin. Each patient's cardiovascular and overall clinical status was monitored over this period. The patients developed chills and rigors, myalgia, and fever between 1-3 h. Tumor necrosis factor-alpha levels increased sharply at 1 h and peaked at 90 min, reaching the baseline concentration thereafter by 6 h. Interleukin-6 levels increased more gradually, peaking at 3 h and reaching the baseline concentration at 8 h. The procalcitonin concentration, which was undetectable (< 10 pg/mL) at 0, 1, and 2 h, was detectable at 4 h and peaked at 6 h, maintaining a plateau through 8 and 24 h (4 ng/mL). There was no elevation of calcitonin concentrations, which remained below 10 pg/mL, the lowest sensitivity of the assay. Procalcitonin was measured by a two-antibody immunoradiometric assay specific for this peptide, with no cross-reactivity with calcitonin, katacalcin, or calcitonin gene-related peptide. We conclude that endotoxin induces the release of procalcitonin systemically, that this increase is not associated with an increase in calcitonin, and that the increase in procalcitonin associated with septicemia in patients may be mediated through the effect of endotoxin described here. Whether procalcitonin participates in the mechanisms underlying inflammation remains to be investigated.

Pyrogenic reactions are characterized by fever, chills, hypotension, or a combination of these developing during or shortly after hemodialysis in a previously asymptomatic patient. The temporal association with treatment implicates exposure of the patient's blood to bacterial pyrogens from contaminated dialysate or a reused dialyzer. Routine body temperature monitoring is recommended to detect these exposures. The current study was prompted by the appearance of several symptomatic febrile episodes in patients who were asymptomatic and afebrile before treatment with high-flux hemodialysis. During a 6 month period, temperatures were measured with a digital oral thermometer before and after 9,605 high-flux hemodialyses in 163 patients. Elevations above 100 degrees F (37.8 degrees C) were observed during or after 33 dialyses in 15 patients. In 18 of these dialyses, the temperature was also elevated before treatment began. Four patients who had no symptoms or fever before dialysis accounted for febrile reactions during 11 of the remaining 15 dialysis treatments. Fever was accompanied by rigors during most of the episodes. Subsequent blood cultures grew Enterococcus faecalis (two), Enterobacter cloacae (two), and Pseudomonas aeruginosa and cepacia (one). All four patients had indwelling silastic double lumen venous catheters (PermCaths), all responded to intravenous antibiotics, and all required eventual removal of the catheter. The apparent precipitation of sepsis by dialysis indicates that shear forces caused by high pulsatile blood flow through the catheter may dislodge organisms that have colonized the lumen. Intraluminal instillation of antibiotics is suggested as a preventative measure.

Meningococcal septicaemia has high mortality, especially when the diagnosis is delayed or missed. Early recognition is not always straightforward, as classic clinical features may be absent or overlooked at initial presentation. Septicaemia without focal infection accounts for 15%-20% of cases of meningococcal disease and is the most worrisome manifestation in terms of diagnosis and outcome; in contrast, meningococcal meningitis is usually straightforward to diagnose, with a relatively good prognosis. Useful early clinical clues to meningococcaemia include: - a haemorrhagic (petechial or purpuric) rash; - blanching macular or maculopapular rash that appears in first 24 hours of illness; - true rigors; - severe pain in extremities, neck or back; vomiting, especially in association with headache or abdominal pain; rapid evolution of the illness; - concern of parents, relatives or friends; - patient age (highest incidence at age 3-12 months, followed by 1-4 and then 15-19 years); and - contact with a patient with meningococcal disease. In addition to specific clues, clinicians should look at the whole pattern of the illness. Timely clinical review is essential if there is doubt about the diagnosis. In any acutely febrile patient, it is prudent to ask "Why is this patient seeking help now?", then "Could this patient have meningococcaemia?".
