The outcome of 53 cases expectantly managed with premature rupture of membranes (PROM) before fetal viability (16 to 25 weeks) was retrospectively reviewed. Forty-one percent of patients developed amnionitis, four had prolonged hospital stays (longer than seven days), and one each had sepsis and pelvic thrombophlebitis. Twenty-two mothers (41%) had no complications. No serious long-term maternal sequelae were noted. Eighteen patients were delivered after 26 weeks, and there were 13 surviving neonates with birth weights ranging from 740 to 2170 g.

The infectious complications associated with implantation of 1,088 Hickman catheters (HCs) in 992 patients reported in 18 published series are presented (including data on 129 previously unreported HCs from our own institution). HCs allow reliable long-term venous access (mean, 92.4 days) with low complication and infection rates (0.30 and 0.14 cases per 100 catheter days, respectively). Exit site infections were the most common form of infection encountered (45.5%), followed by septicemia alone (30.8%), tunnel infections (20.3%), and septic thrombophlebitis (3.5%). Staphylococcus epidermidis (54.1%) and S. aureus (20.0%) were the most common pathogens responsible for catheter infections. HC infections were associated with a low mortality rate (maximum rate of 0.5%). Risk factor analysis of 129 HCs demonstrated that catheter thrombosis was the major risk factor associated with development of catheter infection. Presence of fever, distant infection, neutropenia or antibiotic administration on the day of catheter insertion was not significantly associated with HC infection in this series (although there was a trend suggesting an increased risk of infection of HCs inserted during febrile episodes). Based on observations at our institution and from a review of the literature, tentative recommendations for management of the various types of HC infections are outlined.

An international registry was formed to collate data for patients undergoing attempted catheter ablation of the atrioventricular (AV) junction and insertion of a permanent pacemaker. Over the past 2 years, data was submitted for 127 patients who were followed for a mean of 9.9 +/- 8.2 months. The most common arrhythmia treated was chronic or paroxysmal atrial fibrillation or flutter (78 patients, 61%); the remainder had supraventricular tachycardia due to AV node reentry, ectopic atrial tachycardia, or incorporated an accessory pathway. A single shock of 150 to 400 J was effective in producing chronic third-degree AV block in 45 patients while two or more shocks were used in an additional 45 patients. There was no significant difference in the total cumulative energy used in successful and unsuccessful procedures. Immediate complications related to the shock included ventricular fibrillation (one patient), pericardial tamponade (one patient), and transient hypotension (one patient). No chronic sequelae occurred as a result of these complications. Late complications (1 day to 1 month) included ventricular tachycardia (three patients), sepsis involving the pacemaker pocket (two patients), staphylococcal sepsis from temporary pacing catheter (one patient), thrombophlebitis (one patient), thrombosis of the left subclavian vein (one patient), and hemothorax (one patient). Follow-up evaluation revealed chronic third degree AV block in 90 (71%) and AV conduction resumed but no drugs were required for arrhythmia control in eight (6.5%) and arrhythmia control was achieved with previously ineffective drugs in 16 (13%). Thirteen patients (10%) had no improvement and five of these patients underwent cardiac electrosurgery for direct His bundle ablation.(ABSTRACT TRUNCATED AT 250 WORDS)

Seventy-five episodes of bacteraemia or fungaemia related to indwelling temporary intravenous devices were assessed by the Infectious Diseases Unit of The Westmead Centre, to determine the quality of care of these devices. The estimated incidence of systemic sepsis was 1% for all central venous catheters inserted and 0.1% for all peripheral venous catheters inserted. Sepsis was a major cause of death in 14 of 17 patients who died. Despite the existence of protocols for the insertion, management and early removal of intravenous devices, factors increasing the risk of sepsis included delay in the removal of the intravenous device and the presence of thrombophlebitis. Staphylococcus aureus was the most common isolate (41%); antibiotic resistant Gram-negative rods were also common (38%). It is concluded that continued education of resident and nursing staff is essential to minimize the risk of intravenous catheter-related sepsis.

Anaerobic septicaemia is often a complication of preexisting anaerobic sepsis which is commonly a complication of surgical interference. The predominant anaerobic bacterial isolate in septicaemia if Bacteroides fragilis. Anaerobic cocci and clostridia are not infrequently found as causes of septicaemia. The incidence of polymicrobial septicaemia varies in the different reports. The clinical features of septicaemia due to anaerobic Gram-negative rods vary little from those due to facultative anaerobic Gram-negative rods. The entry portal of bacteroides and clostridia is the gastrointestinal tract and the female genital tract. The portal of entry of anaerobic cocci is the respiratory tract. Anaerobic septicaemia include a high incidence of jaundice, septic thrombophlebitis and metastatic abscess formation. When appropriate antibacterial agents are used for the treatment of anaerobic septicaemia, a mortality rate of 10% is seen while in the absence of treatment the mortality is high, 60-80%. Anaerobic bacteria is an uncommon but important cause of endocarditis. Most cases of anaerobic endocarditis are caused by anaerobic cocci, Propionibacterium acnes and B. fragilis. Predisposing factors and signs and symptoms of endocarditis caused by anaerobic bacteria are similar to those seen in endocarditis with facultative anaerobic bacteria with the following exceptions. There is a lower incidence of preexisting valvular heart disease, a higher incidence of thromboemboli events and a higher mortality rate with anaerobic endocarditis. The article is a review of our present knowledge of the normal anaerobic human microflora in relation to development of septicaemia and endocarditis, virulence factors in anaerobic bacteria, antibiotic susceptibility patterns of anaerobic bacteria and clinical findings in patients with anaerobic septicaemia respectively endocarditis.

Fusobacterium necrophorum septicemia developed in five patients after an oropharyngeal infection. Four patients had sore throat or neck pain, and two had findings of jugular vein septic thrombophlebitis. Metastatic abscesses, including embolic pneumonia, empyema, septic arthritis, and osteomyelitis, also occurred. Four patients recovered and one died. Proper treatment requires recognition of the oropharyngeal source of the septicemia and its differentiation from endocarditis. Antibiotic therapy should be prolonged, and metastatic abscesses drained.

This comprehensive review on puerperal infections covers risk factors, causative bacteria, pathophysiology, diagnosis, therapy of specific entities, and prevention. Puerperal infection is problematic to define especially with antibiotics that change the course of fever. I may present as endometritis (most common), myometritis, parametritis, pelvic abscess, salpingitis, septic pelvic thrombophlebitis or septicemia, and also includes infections of the urinary tract, episiotomy, surgical wounds, lacerations or breast. Each of these is discussed in terms of contributing factors, microbiology, clinical findings, diagnosis, treatment, prevention and complications. Risk factors in general are cesarean section, premature rupture of the membranes, internal fetal monitoring, general anesthesia, pelvic examinations. The most common bacterial involved are group B and other streptococci, E. coli, Gardnerella vaginalis, Gram positive anaerobic cocci, Mycoplasma and pre-existing Chlamydial infections. Diagnosis of the causative organism is difficult because of polyinfection and difficulty of getting a sterile endometrial swab. Diagnosis of the infection is equally difficult because of the wide variety of symptoms: fever, abnormal lochia, tachycardia, tenderness, mass and abnormal bowel sounds are common. Therapy depends of the responsible microorganism, although 3 empirical tactics are suggested while awaiting results of culture: 1) choose an antibiotic for the most common aerobic bacteria; 2) an antibiotic effective against B. fragilis and one for aerobic bacteria, e.g. clindamycin and an aminoglycoside; 3) a nontoxic antibiotic active against most aerobic and anaerobic organisms, e.g. doxycycline or cefoxitin. An example of an infection recently described is pudendal-paracervical block infection, often signaled by severe hip pain. It is associated with vaginal bacteria, is usually complicated by abscess even with antibiotic coverage, and may end in paraplegia or fatal sepsis. Prevention strategies are straightforward: handwashing, changing scrub clothes, isolation of infected patients, restriction of staff contact and prophylactic antibiotics for cesarean section patients at high risk, starting when the cord is clamped.

Four patterns of tissue involvement can be distinguished in sepsis due to gram-negative enteric bacilli. When intense local inflammation predominates, cellulitis or thrombophlebitis results, often with venous or arterial obstruction. Bacteria are present in the affected tissues, but not in sufficient numbers to be seen microscopically. When bacterial proliferation is unchecked by an appropriate leukocyte response, ecthyma gangrenosum, erythema multiforme, or diffuse bullous lesions may occur with minimal clinical or histologic signs of inflammation. In symmetric peripheral gangrene associated with disseminated intravascular coagulation, bland fibrinous deposits are seen in small vessels but neither inflammatory cells nor bacteria are present. The fourth kind of lesion is that seen in bacterial endocarditis. In all four patterns a vascular component is prominent clinically and histologically. The pathogenesis of these lesions is multifactorial; in each individual case the interaction between bacterial and host factors probably determines which clinical picture will result. The appearance of symmetric soft tissue lesions of the extremities in the absence of predisposing local conditions suggests the possibility of sepsis due to gram-negative bacilli, especially if other clinical features indicate that sepsis might be present.

Transient candidemia is common with prolonged intravenous therapy. Sustained candidemia, however, usually indicates a persistent focus of infection. A complication of intravenous therapy not previously emphasized is persistent candidemia caused by candidal suppurative peripheral thrombophlebitis. We report six cases that appeared during intravenous therapy: the infection was characterized by a thrombosed peripheral vein at an intravenous site with manifestations for candida septicemia with or without disseminated candidiasis. In two patients, the source of the process was occult; the examination showed only a thrombosed noninflamed vein. In all cases, surgical exploration showed the thrombosed veins to be suppurative with positive cultures for Candida. Special stains, moreover, showed Candida in the luminal clot and the vascular wall. In the five surviving patients, cure was achieved by excision of the affected vein. Four received a short course of amphotericin B and 5-fluorocytosine, and one patient received amphotericin B only.

A parenteral formulation of rifampicin (Rimactan i.v., Ciba-Geigy, Basel, Switzerland) was administered to 237 critically ill or comatose patients, or patients with gastro-intestinal or absorption problems. There were 160 patients suffering from tuberculosis, 77 suffering from non-tuberculous (non-tb) infections including 30 cases of sepsis, 8 cases of bacterial meningitis and/or cerebral abscess and 9 patients with Legionnaires' disease. The usual daily dose of rifampicin was 450-600 mg, administered in most cases by i.v. bolus (122 cases) or i.v. drip infusion (79 cases) for a period of 1-113 days. Rifampicin was in all cases combined with one or more antimicrobial drug(s). The physicians considered the therapy as successful when the treatment with oral rifampicin could be instituted soon after parenteral administration or when the patients markedly improved their clinical condition. Of a total of 123 tuberculous patients for whom assessment of efficacy was possible, 100 (81.3%) showed favourable clinical results. Of 40 non-tb patients who could be analysed for clinical progress, 32 (80.0%) had a favourable outcome. Special attention should be drawn to the 11 patients with proven staphylococcal infections, of whom 10 were cured clinically and/or bacteriologically. Thrombophlebitis occurred in 10 out of the 237 (4.2%) patients, almost always in patients who were treated for more than 30 days. Systemic unwanted effects occurred in 14 (5.9%); the relationship to the treatment was not always established. Treatment was withdrawn due to unwanted effects in 5 (2.1%) of the 237 patients. Taking into account the severe, life-threatening infections reported, the results suggest that i.v. rifampicin is useful and in some critically ill patients even life-saving. Tolerability was good, even in long-term i.v. administration, although there seems to be the possibility that thrombophlebitis might develop if treatment is continued over 30 days.
