Three years after splenectomy, a middle-aged woman had two separate episodes of fulminant bacterial sepsis. She recovered each time with prompt and appropriate treatment. Her immunologic system was examined and found to be normal with respect to antibody formation against diphtheria and tetanus toxoid, granulocyte killing of staphylococci and serum opsonizing activity. Granulocytes, bursa-equivalent (B) and thymus-dependent (T) lymphocytes and serum immunoglobulins were quantitatively normal. She produced antibody against subcutaneously injected polyvalent pneumococcal vaccine. She demonstrated cutaneous anergy. The literature on this syndrome was reviewed in an attempt to ascertain why hyposplenic patients are subject of fulminant bacterial, chiefly pneumococcal, sepsis. The probably explanation is the delayed production of antibodies against the phagocytic-resistant capsule of certain bacteria which the host had not previously encountered. The incidence of this syndrome appears to be on the order of 0.5 to 1.0%/year for splenectomized older children and adults. As the syndrome is seen chiefly in splenectomized or othewise hyposplenic patients, a causal relationship seems to exist.

Over a six year period, in the Clinic of Communicable Diseases of Cluj Napoca, 2301 patients with staphylococcal infections were admitted to the Clinic, representing 8% of the total number of patients admitted, and 3513 staphylococcal strains were isolated. A number of 43 of the 2301 patients died (1.8%), but staphylococcal infection was actually the cause of death in only 35 cases (1.5%) (septicemia, staphylococcal meningitis and pulmonary infections). Eight of the patients died from the basic disease (hepatitis, tetanus, paratyphoid C fever etc.). A number of 2246 Staphylococcus hemolyticus aureus, 80 non-hemolytic Staphylococcus aureus and 162 Staphylococcus albus strains were isolated; most of the strains were resistant to antibiotics in different proportions.

Systematic microbiological research and correlation of the histopathological findings obtained from random autopsies revealed 23 hitherto undetected clostridial infections including 11 cases of gas gangrene, 4 of septicemia, 3 of bacteremia, and 5 other clostridial infections. The knowledge gained from this study led to clinical diagnosis of several cases of gas gangrene which were confirmed bacteriologically and histologically. Of 8 hospital patients who were thus diagnosed in this surgical clinic, 7 recovered, including a case of gas gangrene of the abdominal wall. The problem in gas gangrene is timely clinical diagnosis. Little is known about gas edema illnesses which are not traumatically conditioned. Recognition of the local and general symptoms (local, violent, yet inappropriate pain in the wound, "unexplained" postoperative secondary bleeding, appearance of tachycardia wholly unrelated to the patient's temperature, sudden shock, rapid deterioration of patient's general condition, jaundice and rise in CPK) makes it possible to diagnose postoperative gas edema in time. 77 infections with isolation of clostridia, seen in 76 patients, are reported. On the basis of clinical and histopathological criteria they have been classified as follows: 22 cases with gas gangrene (clostridial myonecrosis), 16 cases with anaerobic cellulitis, 20 wound infections, 8 cases of septicemia, 5 of bacteriemia, 1 of tetanus, and 5 other clostridial infections.

Group B streptococci (GBS) are the most common cause of bacterial sepsis and meningitis in neonates in the United States. Although the capsular polysaccharide of GBS is an important virulence factor, it is variably immunogenic in humans. In this report, we have increased the immunogenicity of GBS type II polysaccharide by coupling it to tetanus toxoid (TT). Like other GBS capsular polysaccharides, the type II polysaccharide has side chains terminating in sialic acid. Controlled periodate oxidation of native II polysaccharide resulted in the conversion of 7% of sialic acid residues to an analog of sialic acid, 5-acetamido-3,5-dideoxy-D-galactosyloctulosonic acid. TT was conjugated to free aldehyde groups created on the oxidized sialic acid residues by reductive amination. Serum from rabbits vaccinated with type II-TT conjugate (II-TT) vaccine contained antibodies specific to type II polysaccharide as well as to TT, whereas rabbits vaccinated with uncoupled native type II polysaccharide failed to produce a type-specific antibody response. Antibodies elicited by II-TT vaccine were serotype specific and mediated phagocytosis and killing in vitro of type II GBS by human peripheral blood leukocytes. Serum from rabbits vaccinated with II-TT vaccine provided 100% protection in a mouse model of GBS type II infection. Antibodies induced by II-TT vaccine were specific for the native but not desialylated type II polysaccharide, suggesting that an important antigenic epitope of II-TT vaccine was dependent on the presence of sialic acid. Therefore, the coupling strategy which selectively modified a portion of the sialic acid residues of types II polysaccharide before coupling the polysaccharide to TT preserved the epitope essential to protective immunity and enhanced the immunogenicity of the polysaccharide.

In 1987 the worldwide health program, the Safe Motherhood Initiative, was launched in Nairobi by international organizations to combat the alarming rate of maternal mortality resulting from pregnancy and delivery complications that takes 500,000 lives a year, 98% of them in developing countries. Yet the rate has scarcely diminished since ten. In underdeveloped countries maternal mortality is around 400 per 100,000 live births compared to 10-20 in Europe. The rate is the highest in high fertility regions such as Africa and Southeast Asia. The causes are blood loss, infection, hypertensive episodes during pregnancy, rupture of the uterus, and sepsis from botched induced abortion. In postpartum hemorrhage, especially in grand multiparous women, blood transfusion can be lifesaving. However, in a large part of Africa blood is often unusable because of infection with AIDS. In Jamaica and Bangladesh family planning campaigns particularly aimed at adolescents have yielded good results. In Zimbabwe campaigns target mostly men because of their authority. The utility of basic training of traditional birth attendants (TBAs) in delivery is highly questionable, and more thorough going training is being evaluated. Obstacles to reduction of maternal mortality within the Safe Motherhood program include shortage of funds, lack of coordination with local entities, inadequate antenatal care, illiteracy, and cultural barriers. Communication and training activities are essential, as demonstrated by the Matlab project in Bangladesh. The Matlab region had 200,000 people, 83% of women were illiterate, and maternal mortality reached 400 per 100,000 live births. 3 years after schooled midwives trained TBAs and integrated care for pregnant women, and transportation by boat to a newly built clinic was arranged, the maternal mortality rate declined to 140 from 380 per 100,000 live births in the intervention area (p = 0.02) compared to the control region. In the coming year the halving of maternal mortality is envisioned through prevention of anemia, tetanus, and extensive contraceptive use.

Neonatal mice were infected with type III group B streptococcal (GBS) strain M781 by the intraperitoneal route. Age-related susceptibility to challenge was seen within the first 5 days of life. Quantitative blood cultures demonstrated a rapid increase in bacterial numbers during the first 30 h after challenge. Infected pups showed clinical signs of septicemia, and most succumbed within 48 h of challenge. Histopathologic evaluation of the neonates showed bacterial infection within 1 day after challenge. Pregnant adult mice were given a single inoculation of serum raised in rabbits against a tetanus toxoid-conjugated type III GBS polysaccharide vaccine. This serum passively protected 100% of the offspring. This neonatal mouse model of GBS infection and protection may be suitable for study of various forms of intervention.

Two cases of serious infection following catfish spine-related injuries are presented, and the literature on this topic is reviewed. The organisms usually involved in such infections are Vibrio species, Aeromonas hydrophila, Enterobacteriaceae, Pseudomonas species, and components of the flora of the human skin. Irrigation, exploration, and culture of these wounds as well as immunization of the patient against tetanus are recommended. Patients with hepatic disease or chronic illness and immunocompromised individuals are at unusually high risk of fulminant infection due to Vibrio and Aeromonas species and should be treated with antibiotics after sustaining a water-associated wound. Patients with normal host defense mechanisms but with late wound care, punctures involving a bone or a joint, progressive inflammation hours after envenomation, fever, or signs of sepsis are at high risk for secondary infection and should receive definitive wound care and antibiotics. For moderate to severe infections, one of the following combinations constitutes a reasonable empirical regimen: (1) a tetracycline and a broad-spectrum, beta-lactamase-stable beta-lactam antibiotic, or (2) a tetracycline, a beta-lactamase-stable penicillin, and an aminoglycoside.

Between April and September 1991, 415 injured patients were treated at the University Hospital Rebro, Zagreb, 362 at the Department of Surgery and 53 at the Department of Neurosurgery. Infections developed in 15.7% of the injured patients (wound infections in 14.6% and sepsis or meningitis in 1.1% of the injured patients). 88.2% of wound infections as well as all sepsis and meningitis were hospital-acquired infections, while 7.95 of wound infections occurred within 48 h of injuring. The major pathogens, in 90% of cases, were the aerobic bacteria (Enterobacteriaceae, Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter species) while 9% of infections were caused by mixed aerobic-anaerobic flora. One injured patient developed clinical features of gas gangrene. Neither streptococcal wound infections nor tetanus were present in this group of the injured patients.

Maternal mortality is examined from June 1980 to December 1986 at Mulago, Nsambyo, Old Kampala, Rubaga, and Mengo Hospitals in Kampala, Uganda. Clinical or immediate causes, direct and indirect, were recorded from case summary forms based on ICD9 definitions of obstetric complications. The nonabortion maternal mortality rate (NAMMR) was 2.65/1000 deliveries (580 deaths); the abortion-related maternal mortality rate (ARMMR) was 3.58/1000 abortions. The hospital maternal mortality rate was 2.0/1000 deliveries. 75% of maternal deaths of women of 28 weeks' gestation or more had delivered outside the hospital. NAMMR doubled between 1980-86, a statistically significant increase. ARMMR increases were almost significant. 75% were direct obstetric and 21% were indirect obstetric causes. 38% had clinical anemia, 29% had some sepsis, 18% had substantial bleeding, and 14% had obstructed labor. Other contributing conditions were pneumonia, ruptured uterus, laparotomy, evacuations and curettage, malaria, preeclampsia, sickle cell anemia, pulmonary embolism, malnutrition, tetanus, meningitis, prolonged labor, and hepatitis. At admission, 48% were in poor condition, 30% in good condition, and 22% in fair condition. 27% had sickle cell anemia, high blood pressure, multiple pregnancy, or malaria at admission. 64% were admitted within 24 hours after delivery, 67% 1-7 days after delivery, and 92% 7-42 days after delivery. Those in good condition were all admitted 7 days postdelivery. 41% of deaths were due to lack of drugs, 7% lack of fluids, 20% with theater problems, 14% with doctor-related factors, and 3% with midwife-related factors. Better information is needed on mortality before delivery, mortality in hospitals vs. outside, and mortality from abortion, and ectopic and hydatidiform molar pregnancies. An explanation given for the increase in maternal mortality is the decline in economic conditions. Abortion complications may be due to the concealment practiced. Causes are consistent with trends from the 1950s, 1960s, and 1970s in Uganda and developing countries in general. Availability and accessibility of gynecological and obstetric services needs great improvement. Training traditional birth attendants and obtaining rural ambulance services are also needed. Health workers lack creativity and imagination for developing country conditions; scarce resources are not the only problem.

A physician analyzed 1978-80 data on 22 laparoscopic deaths among 106,500 women who underwent sterilization at camps in Gujarat State in India to determine the programmatic and clinical risk factors in these camps. The death rate stood at 20.65/1000,000 procedures compared with 1.5/1000,000 for the US. The laparoscopic sterilization camps were set up in district hospitals, primary health centers, and school buildings. The leading causes of death were peritonitis (9), septicemia (4), and tetanus (2). 5 women also died on the operating table of lignocaine sensitivity (2), cardiac arrest (2), and air embolism (1). The death rate climbed with age (0 deaths for 25 year old, 17 for 26-30 year old, 25.2 for 31-35 year old, and 40.4 for 36-40 year old). It also increased with parity (11.9 for women with 2 living children and 29.8 for those with at least 5 children). 10 of the 22 sterilization deaths were women =or 30 years old with at least 4 children. The number of sterilizations grew 3-fold between 1979-80 and the risk of death grew almost 2-fold. The risk of deaths was especially high during the campaign season (December-March) indicating an increased risk of speedy completions to meet quotas. Surgeons with 6 months experience in laparoscopic sterilization were responsible for most deaths (67%) in camps with 50-100 sterilizations. The case fatality rate for these surgeons was 54.2/1000,000 compared with 8.1 for surgeons with at least 25 months, experience. The same percentage of deaths in these camps occurred to women operated on in school buildings. The case fatality rate for school building operations was 71/1000,000 compared with 15.4 for district hospitals and 13.5 for primary health centers. An unacceptable risk would remain even if school buildings were excluded and laparoscopic sterilization training would not occur at sterilization camps. Improved sterilization of equipment and improved surgical judgment of complications could have prevented many deaths. A medical audit of camps services is justified.
