Abstract
BACKGROUND In terms of maternal morbidity and mortality, the puerperium is just as significant as pregnancy and childbirth. Nearly half of all maternal deaths occur in the time after delivery. METHODS This review is based on pertinent articles in English and German from the years 2000- 2020 that were retrieved by a selective search in MEDLINE and EMBASE, as well as on the available guidelines in English and German and on German-language textbooks of obstetrics. RESULTS The most common and severe complications are, in the post-placental phase, bleeding and disturbances of uterine involution; in the first seven days after delivery, infection (e.g., endomyometritis, which occurs after 1.6% [0.9; 2.5] of all births) and hypertension-related conditions. Thromboembolism, incontinence and disorders of the pelvic floor, mental disease, and endocrine disturbances can arise at any time during the puerperium. In an Australian study, the incidence of embolism was 0.45 per 1000 births, with 61.3% arising exclusively after delivery. CONCLUSION Basic familiarity with the most common and severe diseases in the puerperium is important for non-gynecologists as well, among other things because highly acute, lifethreatening complications can arise that demand urgent intervention.

Oral and intramuscular treatment options for early postpartum endometritis in low-resource settings: a systematic review. Obstet Gynecol 2015; 125:789-800.

Abstract
OBJECTIVE To suggest options for oral and intramuscular antibiotic treatment of early postpartum endometritis in low-resource community settings where intravenous antibiotics are unavailable. DATA SOURCES Studies were identified through MEDLINE from inception through December 2014. Search terms included [("anti-bacterial agents [MeSH]" or "anti-infective agents [MeSH]") and ("endometritis [MeSH]" or "puerperal infection [MeSH]")]. A second search using the terms [("endometritis or endomyometritis or puerperal infection) and ("antibiotics or antimicrobials or anti-bacterial agents or anti-infective agents)"] was also used. Additionally, all references from selected articles were reviewed, a hand-search of a subject matter expert library was conducted, and a search of ClinicalTrials.gov was performed. METHODS OF STUDY SELECTION We conducted a systematic review of the literature in two phases. Phase I provides a summary of clinical cure data from prospective studies of oral and intramuscular antimicrobial regimens as well as summarizes evidence from trials of intravenous antimicrobials. Phase II is a quantitative analysis of pathogens from intrauterine postpartum endometritis samples. Based on these results, and with consideration of existing recommendations for antibiotic use during breastfeeding, we suggest oral and intramuscular antimicrobial options for the treatment of early postpartum endometritis after vaginal delivery in low-resource settings. TABULATION, INTEGRATION, AND RESULTS Reports involving oral or intramuscular antimicrobial treatment of postpartum endometritis are rare and of generally poor quality. Antimicrobial trials of postpartum endometritis treatment and intrauterine microbiology studies suggest five antimicrobial regimens may be effective: oral clindamycin plus intramuscular gentamicin, oral amoxicillin-clavulanate, intramuscular cefotetan, intramuscular meropenem or imipenem-cilastatin, and oral amoxicillin in combination with oral metronidazole. CONCLUSION This review provides suggestions for oral, intramuscular, and combined antimicrobial regimens that may warrant additional study. Experimental trials should consider clinical effectiveness, safety and side effects profiles, and feasibility of community-based treatment.

Abstract
BACKGROUND Postpartum endometritis occurs when vaginal organisms invade the endometrial cavity during the labor process and cause infection. This is more common following cesarean birth. The condition warrants antibiotic treatment. OBJECTIVES Systematically, to review treatment failure and other complications of different antibiotic regimens for postpartum endometritis. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2014) and reference lists of retrieved studies. SELECTION CRITERIA We included randomized trials of different antibiotic regimens after cesarean birth or vaginal birth; no quasi-randomized trials were included. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS The review includes a total of 42 trials, and 40 of these trials contributed data on 4240 participants.Regarding the primary outcomes, seven studies compared clindamycin plus an aminoglycoside versus penicillins and showed fewer treatment failures (risk ratio (RR) 0.65, 95% confidence interval (CI) 0.46 to 0.90). There were more treatment failures in those treated with an aminoglycoside plus penicillin when compared to those treated with gentamycin/clindamycin (RR 2.57, 95% CI 1.48 to 4.46). There were more treatment failures (RR 1.66, 95% CI 1.01 to 2.74) and wound infections (RR 1.88, 95% CI 1.08 to 3.28) in those treated with second or third generation cephalosporins (excluding cephamycins) versus those treated with clindamycin plus gentamycin. In four studies comparing once-daily with thrice-daily dosing of gentamicin, there were fewer failures with once-daily dosing. There were more treatment failures (RR 1.94, 95% CI 1.38 to 2.72) and wound infections (RR 1.88, 95% CI 1.17 to 3.02) in those treated with a regimen with poor activity against penicillin-resistant anaerobic bacteria as compared to those treated with a regimen with good activity against penicillin-resistant anaerobic bacteria. There were no differences between groups with respect to severe complications and no trials reported any maternal deaths.Regarding the secondary outcomes, three studies that compared continued oral antibiotic therapy after intravenous therapy with no oral therapy, found no differences in recurrent endometritis or other outcomes. Four trials that compared clindamycin plus aminoglycoside versus cephalosporins identified fewer wound infections in those treated with clindamycin plus an aminoglycoside (RR 0.53, 95% CI 0.30 to 0.93). There were no differences between groups for the outcomes of allergic reactions. The overall risk of bias was unclear in the most of the studies. The quality of the evidence using GRADE comparing clindamycin and an aminoglycoside with another regimen (compared with cephalosporins or penicillins) was low to very low for therapeutic failure, severe complications, wound infection and allergic reaction. AUTHORS' CONCLUSIONS The combination of clindamycin and gentamicin is appropriate for the treatment of endometritis. Regimens with good activity against penicillin-resistant anaerobic bacteria are better than those with poor activity against penicillin-resistant anaerobic bacteria. There is no evidence that any one regimen is associated with fewer side-effects. Following clinical improvement of uncomplicated endometritis which has been treated with intravenous therapy, the use of additional oral therapy has not been proven to be beneficial.

Abstract
BACKGROUND Postpartum endometritis, which is more common after cesarean section, occurs when vaginal organisms invade the endometrial cavity during labor and birth. Antibiotic treatment is warranted. OBJECTIVES The effect of different antibiotic regimens for the treatment of postpartum endometritis on failure of therapy and complications was systematically reviewed. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's trials register (30 January 2004). SELECTION CRITERIA Randomized trials of different antibiotic regimens for postpartum endometritis, after cesarean section or vaginal birth, where outcomes of treatment failure or complications were reported were selected. DATA COLLECTION AND ANALYSIS We abstracted data independently and made comparisons between different types of antibiotic regimen based on type of antibiotic and duration and route of administration. Summary relative risks were calculated. MAIN RESULTS Thirty-eight trials with 3983 participants were included. Fifteen studies comparing clindamycin and an aminoglycoside with another regimen showed more treatment failures with the other regimen (relative risk (RR) 1.44; 95% confidence interval (CI) 1.15 to 1.80). Failures of those regimens with poor activity against penicillin resistant anaerobic bacteria were more likely (RR 1.94; 95% CI 1.38 to 2.72). In three studies that compared continued oral antibiotic therapy after intravenous therapy with no oral therapy, no differences were found in recurrent endometritis or other outcomes. In four studies comparing once daily with thrice daily dosing of gentamicin there were fewer failures with once daily dosing. There was no evidence of difference in incidence of allergic reactions. Cephalosporins were associated with less diarrhea. REVIEWERS' CONCLUSIONS The combination of gentamicin and clindamycin is appropriate for the treatment of endometritis. Regimens with activity against penicillin- resistant anaerobic bacteria are better than those without. There is no evidence that any one regimen is associated with fewer side effects. Once uncomplicated endometritis has clinically improved with intravenous therapy, oral therapy is not needed.

Abstract
BACKGROUND Post-partum endometritis, which is more common after cesarean section, occurs when vaginal organisms invade the endometrial cavity during labour and birth. Antibiotic treatment is warranted. OBJECTIVES The effect of different antibiotic regimens for the treatment of postpartum endometritis on failure of therapy and complications was systematically reviewed. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's trials register and the Cochrane Controlled Trials Register. Date of last search: June 2001. SELECTION CRITERIA Randomised trials of different antibiotic regimens for postpartum endometritis, after cesarean section or vaginal birth, where outcomes of treatment failure or complications were reported were selected. DATA COLLECTION AND ANALYSIS Data were abstracted independently by the reviewers. Comparisons were made between different types of antibiotic regimen, based on type of antibiotic and duration and route of administration. Summary relative risks were calculated. MAIN RESULTS Forty-seven trials were included. Overall the studies were methodologically poor. In the intent-to-treat analysis, fifteen studies comparing clindamycin and an aminoglycoside with another regimen showed more treatment failures with another regimen (relative risk (RR) 1.32; 95% confidence interval (CI) 1.09-1.60). Failures of those regimens with poor activity against penicillin resistant anaerobic bacteria were more likely (RR 1.53; 95% CI 1.10-2.13). In four studies that compared continued oral antibiotic therapy after intravenous therapy, no differences were found in recurrent endometritis or other outcomes. There was no evidence of difference in incidence of allergic reactions. Cephalosporins were associated with less diarrhea.

Abstract
OBJECTIVE Our goal was to evaluate an antibiotic protocol for treatment of postcesarean endometritis. STUDY DESIGN Endometritis was diagnosed as a persistent fever > or =100.4 degrees F beyond 24 hours after cesarean delivery and one or more of the following: uterine tenderness, tachycardia, foul lochia, or leukocytosis. Antibiotic therapy included gentamicin plus clindamycin and ampicillin (or vancomycin) as a triple antimicrobial in 148 women. Antibiotic failure was defined as persistent fever after 5 days of antibiotics and 72 hours of triple antibiotics. RESULTS Between 1993 and 1996, 322 of 1643 (20%) women were diagnosed with postcesarean endometritis. One hundred seventy-four patients (54%) were cured with clindamycin-gentamicin, and 129 who additionally received ampicillin or vancomycin (40%) were cured. Nineteen of the 322 (6%) women had persistent fever despite triple antibiotics. Of these, 6 had a wound complication, 12 were suspected to have antimicrobial resistance, and 1 had an infected hematoma. CONCLUSION A prospective protocol consisting of clindamycin-gentamicin plus the selective addition of ampicillin or vancomycin cured 303 of 322 (94%) women with postcesarean endometritis.

Abstract
Chorioamnionitis complicates 1% to 2% of all pregnancies and may affect 10% of women with certain risk factors. Intraamnionic infection may result in devastating morbidity for both the fetus and the mother. Also, chorioamnionitis is associated with higher cesarean section rates. As demonstrated earlier, endometritis is a common complication of cesarean delivery alone. Nevertheless, antibiotic prophylaxis has been shown to reduce postpartum morbidity. In the face of chorioamnionitis and a cesarean delivery, the risk of developing endometritis increases exponentially. However, if appropriate antibiotic therapy is instituted at the time of diagnosis, fetal and maternal outcomes improve dramatically. Similar to chorioamnionitis, endometritis is usually polymicrobial in nature. The preponderance of the organisms isolated are anaerobic. Established risk factors include operative delivery, prolonged ruptured fetal membranes, and prolonged labor. The diagnosis is based primarily on clinical examination with fever and the exclusion of other sources of extrapelvic infection. Once the diagnosis is established, appropriate empiric antibiotics are instituted. Antibiotic therapy should be continued until the patient is afebrile and asymptomatic for 24 to 36 hours. Over the past 20 years, the use of single-agent therapy in these serious infections has been shown to be safe as well as effective. Once successful therapy is completed, the patient is discharged home with no oral antibiotics.

Abstract
OBJECTIVE We used meta-analysis to compare clinical cure and success rates for parenteral clindamycin 600 mg q8h or 900 mg q8h therapy to treat adult intraabdominal or female pelvic infections. DATA SOURCES We located English-language articles describing clindamycin use in humans using MEDLINE, International Pharmaceutical Abstracts, and Embase and from personal and drug information center files, plus all article references. STUDY SELECTION Eligible studies used parenteral clindamycin 600 mg q8h or 900 mg q8h to treat intraabdominal or pelvic infection in at least 1 arm of a study and provided a definition of clinical outcome. Accepted were comparative trials in adults who were not critically ill or expected to die. DATA SYNTHESIS The DerSimonian and Laird method was used to calculate weighted overall success rates for cure and success (cure plus improved) rates along with 95% confidence intervals for each dosage in intraabdominal and pelvic infections. Regimens were compared with respect to both cure and success rates using the Mann-Whitney U test. MAIN RESULTS Twenty-three articles were eligible for inclusion. Abdominal cure rates were 75.6% and 90.5% for clindamycin 600 mg q8h and 900 mg q8h, respectively (p = 0.03): success rates were 89.8% and 92.5%, respectively (p = 0.29). Pelvic cure rates were 82.8% and 89.4%, respectively (p = 0.51): success rates were 87.2% and 89.9%, respectively (p = 0.51). CONCLUSIONS In pelvic infections, a dosage of clindamycin 600 mg q8h appears to be clinically acceptable for all patients. Although clinical outcomes for intraabdominal infections are generally similar for both regimens, the significantly higher cure rate with a dosage of clindamycin 900 mg q8h suggests that dosage recommendations should be patient specific.

Abstract
OBJECTIVE The hypothesis of the study is that cefotetan and cefoxitin will be equally efficacious and safe in the treatment of post-cesarean section endometritis. STUDY DESIGN In a double-blind, randomized manner 140 patients with post-cesarean section endometritis were treated with cefotetan, 2 gm intravenously every 12 hours, or cefoxitin, 2 gm intravenously every 6 hours. They were followed prospectively for clinical response and side effects. Cure rates between the two groups were compared with the chi 2 test. RESULTS The cure rates were 83% for cefotetan and 79% for cefoxitin (p = 0.56). No patient required a change in therapy due to adverse effects, and no abnormal bleeding occurred. CONCLUSION In this study cefotetan and cefoxitin appeared equally effective in treating endometritis with no difference in side effects or complications.

Abstract
To evaluate the safety and efficacy of an abbreviated course of antibiotic therapy in postpartum endomyometritis, 109 patients with endomyometritis were randomized to three study groups. All were treated with clindamycin and tobramycin until afebrility and clinical signs of disease were absent. Patients in group I received antibiotics for greater than or equal to 24 hours, group II received therapy for greater than or equal to 48 hours, and group III received antibiotic therapy for greater than or equal to 48 hours that preceded a 7-day course of oral Augmentin. The groups were similar in size and in demographic and clinical parameters. Two patients from each group required a third antibiotic, and no patient required rehospitalization. Group III required more days of antibiotic therapy than did group I, 2.9 versus 2.1 days (p less than 0.01), and cost $412.00 more per patient. This data strongly suggest that a short course of antibiotic therapy is efficacious and safe and would result in substantial monetary savings.

Abstract
Although genital and wound infections are not uncommon in the puerperal patient, these cases often resolve with appropriate medical therapy-usually a rational program of antibiotics and supportive therapy. In the severely ill obstetric patient, however, surgical intervention may be the only choice of management.

Abstract
A retrospective analysis was made of 27 maternal deaths after cesarean section occurring over a 5-year period. Sepsis was the single most important cause of maternal death (81.5%). The commonest indications for the cesarean sections were obstructed labor (59.3%) and cord prolapse (18.5%). The causes of maternal deaths were classified as avoidable and recommendations were made for their prevention.

Abstract
The development of chorioamnionitis and endomyometritis has traditionally required treatment with broad-spectrum antibiotic therapy and extended hospitalization. In the past, once parenteral antibiotic therapy was instituted, it was continued for 5 to 7 days and until the patient remained afebrile for 48 hours. To shorten the length of hospital stay, the length of parenteral antibiotic administration was reduced and an oral antibiotic was added, to complete a 7- to 10-day course of therapy. We evaluated the effectiveness of an even shorter course of parenteral antibiotics without the addition of oral antibiotics. Forty-two patients with chorioamnionitis and 64 with endomyometritis were enrolled in the study. Antibiotic therapy was continued until the patient's temperature was less than 99.5 degrees F for 12 to 24 hours. Of the 106 patients, only two were readmitted, both as a result of superficial wound separation. No patient had an infectious complication. A shorter course of parenteral antibiotics without the addition of an oral antibiotic gives results comparable to the standard extended treatment regimens, but is advantageous with respect to cost, patient compliance, and hospital stay.

Abstract
The direct and indirect costs associated with either moxalactam or clindamycin plus gentamicin as treatment for endomyometritis after emergent cesarean section were compared in an open, randomized prospective trial of 114 patients. A total of 58 patients were assigned to receive moxalactam, 2 g intravenously (i.v.) every 8 h for 5 doses, followed by 2 g every 12 h and prophylactic vitamin K (10 mg) intramuscularly, and 56 patients were assigned to receive clindamycin (600 mg) i.v. every 6 h plus gentamicin (1.5 mg/kg) i.v. every 8 h. Prothrombin times were measured in moxalactam-treated patients, and patients treated with clindamycin plus gentamicin had urinalyses and blood urea nitrogen and serum creatinine determinations performed before and after treatment. Also, gentamicin levels in serum were determined as clinically indicated. A satisfactory treatment response was defined as the resolution of signs and symptoms of endomyometritis within 3 days of the start of antibiotic therapy. Satisfactory responses were demonstrated in 78% of the moxalactam-treated patients and 84% of patients treated with clindamycin plus gentamicin. Mean hospital costs for laboratory tests ($30.30 versus $4.53) and mean patient charges for laboratory tests ($76.39 versus $27.81) and medications ($539.45 versus $421.82) were significantly higher in patients treated with clindamycin plus gentamicin (P less than 0.05), while mean medication costs to the hospital were greater in the moxalactam group ($255.47 versus $195.68; P less than 0.05). However, total patient charges and total hospital drug-associated costs were not significantly different for the two group. In this tudy, moxalactam was similar in efficacy and, despite its higher acquistion cost, was comparable in total hospital costs and patient charges to clindamycin plus gentacmicin in treating endomyometritis.

Abstract
The clinical efficacy and safety of cefotetan was assessed in two multicenter clinical trials involving 335 evaluable patients hospitalized with obstetric and gynecologic infections. In Study I, cefotetan was compared with moxalactam and in Study II, cefotetan was compared with cefoxitin. The clinical response rate in Study I was 67 of 70 patients for cefotetan (96 percent) and 33 of 34 patients (97 percent) for moxalactam. In Study II, the clinical response rate was 138 of 147 patients in the cefotetan group (94 percent) and 76 of 84 patients in the cefoxitin group (91 percent). For the patients with bacteriologic response data, 196 of 205 cefotetan patients (96 percent), 23 of 24 moxalactam patients (96 percent), and 70 of 75 cefoxitin patients (93 percent) had a satisfactory bacteriologic response. Cefotetan was well tolerated and produced no major adverse reactions. The mean amount of cefotetan given was lower than that of moxalactam or cefoxitin.

Abstract
Pathogens that cause acute polymicrobial female pelvic infections usually do not differ from those that compose the normal flora of the lower reproductive tract. Accurate identification of these bacteria is difficult because cultures obtained via the lower tract can easily be contaminated. Although use of a double-lumen catheter-protected brush culture cannot completely eliminate the risk of contamination, it is the least invasive method for obtaining culture material from the upper reproductive tract. Compounding the problem of accurately identifying pathogens that cause acute upper tract infections is the fact that bacteria appear to be present in the upper tracts of asymptomatic women with normal examinations. Because of these problems and because of the polymicrobial nature of these infections, empiric therapy frequently includes more than one antimicrobial agent. Newer, semisynthetic penicillins and cephalosporins have expanded spectrums of in vitro activity against most of the bacteria frequently recovered from pelvic infection sites. Comparative clinical trials have shown these agents to be as effective when used alone as is combination therapy. With few exceptions, empiric monotherapy with one of these newer antimicrobials will be curative for women with acute upper tract infection, will have less potential toxicity, will require less space, materials, and manpower to administer, and will be less expensive.

Abstract
beta-Lactam antibiotics are the most commonly used antibiotics in obstetrics and gynecology. However, they are susceptible to inactivation when attacked by beta-lactamase, an enzyme produced by many bacterial species. During the past three decades, numerous penicillins and cephalosporins have been made with a stable beta-lactam ring that resists enzyme attack. More recently enzyme inhibitors have been discovered that inactivate beta-lactamase. The combination of an enzyme inhibitor with a beta-lactam antibiotic, such as ampicillin, restores the antimicrobial activity of the beta-lactam against formerly resistant strains of staphylococci, Haemophilus influenzae, Enterobacteriaceae, and Bacteroides fragilis.

Abstract
Patients who contract genital tract infections are predominantly young, are otherwise healthy, and generally respond well to treatment for bacterial infections. These infections are most commonly polymicrobial in etiology, with several noteworthy exceptions. Often there is an inciting event such as childbirth, surgical intervention, pregnancy termination or intrauterine contraceptive device insertion. With treatment, prognosis for cure is excellent; however, sequelae such as recurrent infections, infertility, or ectopic pregnancy can be serious. Bacteria encountered in the female genital tract can be divided into aerobic and anaerobic organisms. Among the aerobic gram-positive organisms, several varieties of streptococci such as Group B streptococci and enterococci occur frequently. Staphylococcus aureus is an infrequent but important pathogen. Among the aerobic gram-negative organisms, the most common is Escherichia coli. Klebsiella sp. and Proteus sp. occur in about 5% of genital tract infections. Species that are more resistant to antibiotics, such as Pseudomonas aeruginosa and Enterobacter sp., occur in approximately 1% or 2% of these cases and are more likely to appear in patients who have previously received antibiotic therapy or who have been hospitalized for some time. Among the anaerobic organisms, the most common gram-positive isolates are Peptostreptococci and Peptococci. Clostridia sp. occurs less frequently. Among the anaerobic gram-negative organisms, the Bacteroides sp. most frequently encountered are Bacteroides bivius and Bacteroides disiens. Bacteroides fragilis is still a common problem but appears to be less predominant. Other organisms encountered are Chlamydia trachomatis, the genital mycoplasmas, yeasts, protozoa, and viruses.

Abstract
A new single-antibiotic combination of ticarcillin and clavulanic acid was compared with the standard two-drug regimen of clindamycin and gentamicin in the treatment of post-cesarean endomyometritis. The regimens were as follows: 3 g of ticarcillin plus 100 mg of clavulanic acid intravenously every four hours; or 600 mg of clindamycin intravenously every six hours plus 3 to 5 mg/kg per day of gentamicin intramuscularly. The prospective randomized schedule was calculated such that half the patients were assigned to each treatment group. The diagnosis of endomyometritis was based upon an elevated oral temperature of 100.4 degrees F or higher on any two occasions, excluding the first 24 hours after delivery, uterine tenderness, and the absence of other foci of infection. Lochial discharge was foul in most cases. Forty-seven patients were treated. Treatment was successful in all patients who received clindamycin and gentamicin; ticarcillin plus clavulanic acid failed in two of 23 (9 percent) patients. Patients in whom treatment failed did not appear to be different from those in whom treatment was successful on demographic variables or in terms of risk factors for endomyometritis. The difference between the treatment failure rates was not statistically significant. This study suggests that the single-drug combination of ticarcillin plus clavulanic acid is effective in the treatment of post-cesarean endomyometritis when compared with the standard regimen of clindamycin and gentamicin.

Abstract
Antimicrobial combinations have been widely utilized since the beginning of the chemotherapeutic era. This is true despite the fact that the use of such combinations has a number of potential disadvantages, including (1) antibiotic antagonism; (2) an increased incidence of toxicity; (3) the emergence of multi-resistant organisms; (4) promotion of a false sense of security; and (5) increased expense. The reasons generally given for the use of such combinations include (1) antimicrobial synergism, (2) suppression of antimicrobial resistance, (3) decreased toxicity, and (4) broader coverage. Although there are clearly some situations in which synergistic combinations have been shown to be useful (such as in the treatment of enterococcal endocarditis and severe Pseudomonas infections), the use of combination therapy to reduce the emergence of resistance (excluding the treatment of mycobacterial infections and of infections in which rifampin is used) or to reduce toxicity has not met with widespread success. Indeed, most combinations are used simply to broaden the spectrum of antimicrobial coverage. The development of new penicillins and cephalosporins with broader spectra of activity has raised the distinct possibility that these drugs could be used as single agents for the treatment of most serious infections. Although comparative studies performed to date suggest that the new broad-spectrum penicillins and cephalosporins may be useful as single agents in the treatment of infections in a variety of clinical situations in which combinations are now commonly employed, additional studies enrolling greater numbers of patients are necessary to determine whether these agents can replace combination therapy. The use of single-drug therapy in the management of febrile episodes and documented infections in neutropenic patients remains problematic because of the greater likelihood of infections with organisms such as Pseudomonas aeruginosa, in which case combination therapy is often required. Earlier studies have clearly documented that combinations of antibiotics that are synergistic are more effective in treating bacteremias and other serious infections in neutropenic patients than are combinations that have failed to demonstrate synergism. Because of the increased activity of some of the newer drugs, such as ceftazidime, against P. aeruginosa it is possible that such agents could be used as monotherapy for patients with severe neutropenia. This possibility is an attractive one, but it should be studied carefully to make certain that it will not be associated with significant failure due to the emergence of resistant organisms.

Abstract
The clinical efficacy of moxalactam versus clindamycin/tobramycin was evaluated in a comparative, randomized, prospective study. Sixty patients were treated: 30 with moxalactam and 30 with clindamycin/tobramycin. There were 15 cases of tuboovarian abscess, 36 cases of severe pelvic inflammatory disease with peritonitis, eight cases of endomyometritis, and one wound abscess. Aerobic and anaerobic cultures from the sites of infection yielded 441 microorganisms from 53 patients; an average of 8.3 bacteria per infection (4.5 anaerobes and 3.8 aerobes). The infections tended to be mixed aerobic-anaerobic with anaerobes isolated in 90% of cases. The most frequently isolated possible pathogens were Bacteroides sp. (37), Bacteroides bivius (23), Bacteroides asaccharolyticus (12), Peptococcus asaccharolyticus (29), Peptostreptococcus anaerobius (19), unidentified anaerobic gram-positive cocci (18), Escherichia coli (17), nonhemolytic streptococci (16), Neisseria gonorrhoeae (13), and Gardnerella vaginalis (38). Clinical cure was noted in 29 of 30 moxalactam-treated and 29 of 30 clindamycin/tobramycin-treated patients. Moxalactam was effective in five of six cases of tuboovarian abscess, all 22 cases of pelvic inflammatory disease with peritonitis, the one case of endomyometritis and the one wound abscess. Clindamycin/tobramycin was effective in eight of nine cases of tuboovarian abscess, all 14 cases of pelvic inflammatory disease with peritonitis, and all seven cases of endomyometritis. No adverse hematologic, renal, or hepatic effects were noted with either regimen.

Abstract
Fifty-five patients with soft tissue pelvic infections were treated with imipenem/cilastatin 500 mg intravenously every six hours for a minimum of four days. Six patients were unevaluable, one because of protocol non-compliance and five because no pathogen was isolated. At enrollment, mean temperature was 39.5 degrees C and the mean white blood cell count was 14,700. Of 49 evaluable patients, 43 (87.8 percent) had complete clinical cures. In three of the six patients with clinical failures, subsequent alternative antibiotic treatment also failed and they required operative intervention for pelvic abscess. In two of the patients with failures, antibiotic-associated pseudomembranous colitis developed after three days of imipenem/cilastatin therapy, requiring discontinuation of the medication. At the time of discontinuation, both patients had clinical failures. All microbiologic isolates were susceptible to imipenem/cilastatin, although at least one pathogenic organism persisted in two patients with clinical failures despite apparent in vitro susceptibility of the organism to imipenem/cilastatin. Imipenem/cilastatin is a promising agent for the empiric treatment of serious obstetric and gynecologic infections although surgery often remains a necessary treatment for pelvic abscess regardless of initial antibiotic choice.

Abstract
Prophylactic antibiotics have been shown to be effective in decreasing the incidence of febrile morbidity associated with cesarean section after labor. However, the relative effectiveness of different single antibiotics has been studied infrequently, and these investigations have been limited by small patient samples. Several new, broad-spectrum antibiotics are now available, and any further benefit from more traditional antibiotics for surgical prophylaxis remains untested. A randomized prospective double-blind therapeutic trial was therefore undertaken to compare the value of a first-generation cephalosporin (cefazolin) with a new third-generation cephalosporin (moxalactam). Between July 1981 and June 1983, 254 qualifying women who underwent primary cesarean section after labor were randomly chosen for either of the two treatment groups. Although not statistically significant, the rates of febrile morbidity, wound infection, and endometritis were less for those treated with cefazolin (4.0, 3.2, and 0.8%, respectively) than for those treated with moxalactam (9.2, 7.7, and 1.6%, respectively). No serious adverse effects were apparent in the mother and newborn infant from short-term exposure to either drug. Although the newer, more expensive, and broader-spectrum cephalosporin, moxalactam, was associated with a low postoperative febrile morbidity rate and short postpartum hospitalization, it was no more beneficial than cefazolin.

Abstract
The susceptibility of 46 clinical isolates of Bacteroides bivius to amoxicillin, cefotaxime, cefoxitin, ceftizoxime, cephaloridine, cephalothin, moxalactam, penicillin G, amoxicillin plus clavulanic acid in a ratio of 2:1, carbenicillin, cefamandole, and ceftazidime was determined by an agar dilution technique. For the first eight agents susceptibility testing was also done with the addition of clavulanic acid (0.75 microgram/ml). For all agents, beta-lactamase-positive strains (35, using a nitrocefin slide test) were inhibited at higher concentrations than beta-lactamase-negative strains. Clavulanic acid reduced the susceptibility of the beta-lactamase-positive strains to the level of the beta-lactamase-negative strains to all agents. We prepared crude extracts of beta-lactamase from six strains. Activity against nitrocefin was directly related to their susceptibilities. The beta-lactamase had a mixed-substrate profile, hydrolyzing both penicillins and cephalosporins. Our results suggest a slow inactivation of cefoxitin, ceftizoxime, and moxalactam by the beta-lactamase. Clavulanic acid and cefoxitin inhibited the enzyme, whereas p-hydroxymercuribenzoate and cloxacillin did not. Thus, there was a clear relationship between beta-lactamase activity and susceptibility to beta-lactams, including cefoxitin and third-generation cephalosporins. The substrate and inhibition profiles of the B. bivius beta-lactamase were different from those of enzymes found in the "B. fragilis group."

Abstract
A randomized comparison of ceftazidime versus clindamycin-tobramycin was performed for the treatment of obstetrical and gynecological infections. Entry criteria were an oral temperature of greater than or equal to 38 degrees C and a clinical diagnosis of endometritis, salpingitis, or pelvic cellulitis after hysterectomy. All patients with endometritis had cultures of intrauterine material obtained via a transcervical single-lumen catheter. The patients with pelvic cellulitis had material from the vaginal apex aspirated for culture, and all patients with salpingitis had a culdocentesis for culture of intraperitoneal material. Of 38 patients who received ceftazidime, 34 had endometritis after cesarean section, 3 had endometritis after abortion, and 1 had pelvic cellulitis. Of 39 patients who received clindamycin-tobramycin, 35 had endometritis after cesarean section, 3 had salpingitis, and 1 had pelvic cellulitis. The most common bacterial isolates were Lactobacillus sp., Bacteroides bivius, Escherichia coli, other gram-negative aerobic bacilli, group B streptococci, and other aerobic streptococci. Bacteremia occurred in 9.0% of the patients. Of the patients receiving clindamycin-tobramycin and ceftazidime, 34 (87.2%) and 34 (89.5%), respectively, responded to therapy. All the clinical failures occurred in patients with endometritis after cesarean section. Clinical failures had persistent fever despite 3 or more days of treatment. One of the patients receiving clindamycin-tobramycin developed an urticarial rash after her infection had resolved. No patient in either group developed diarrhea. In these small groups of patients, there were no significant differences in cure rate, side effects, or length of hospital stay.
