From 1976 to 1981, 25 cases of S. pyogenes septicemia were diagnosed at the University Medical Center, Lausanne, Switzerland, in 5 children and 20 adults. The twenty adult patients are described. The age range was from 24 to 94 years. The portal of entry was the skin (erysipelas, skin ulcers, surgical wounds) in 12 cases, the respiratory tract (upper 3, lower 3) in 6 cases, and the vagina in 2 cases. All except 3 patients were acutely ill with high temperature (39 degrees C) and toxic appearance. None had an underlying malignancy. The clinical course was complicated in 5 patients, i.e. septic arthritis (2), pulmonary abscess (1), endocarditis (1) and acute rheumatic fever (1). After initiation of penicillin therapy, temperature and symptoms resolved only slowly (mean 11 days). Four patients died from infection. In 2 of them the antibiotic treatment had been delayed. When a patient exhibits clinical signs of septicemia and muco-cutaneous lesions suggestive of a portal of entry, S. pyogenes septicemia should be suspected. Complications are frequent and the prognosis remains poor despite early adequate antibiotic treatment.

Infections in patients with gynecologic malignancies occur frequently and are the cause of death in 50 to 60% of the cases. The patient with cancer is a compromised host with an increased susceptibility to infection due to the malignancy itself on the one hand and due to therapeutic-modalities, like extensive surgical procedures, radiation- and cytotoxic chemotherapy on the other hand. Aetiologically these infections are mostly due to a disruption of anatomic structures which normally prevent the invasion of exogenous or endogenous microorganisms, or to obstructive processes or to tumour necrosis. Septicaemia can result from propagation of such a localized infection beyond the site of the tumour. The causative pathogens infecting the compromised host are mostly members of the indigenous microbial flora of the genital tract, which is influenced by surgery, irradiation and chemotherapy. Postoperatively in the vaginal vault the number of most potentially pathogenic aerobic and anaerobic bacterial species is higher, polymicrobial mixed infections are frequent. Neither the intracavitary radiation-therapy with Radium or Iridium-192 (afterloading) nor the external high-voltage therapy decrease the number of pathogenic bacterial species in the uterus and in the vagina of patients with cervical or endometrial cancer. The symptoms of infection in cancer patients can be "masked". Fever in patients with genital malignancies is mostly due to local infections and influences the prognosis negatively. The 5-year survival rate of irradiated patients with fever is significantly lower. Infections following radical hysterectomy, irradiation and/or cytotoxic chemotherapy like pelvic abscesses, peritonitis, pneumonia and septicaemia can be fatal. Urinary-tract-, wound- and vaginal vault-infections occur frequently, but are rarely severe. Therapeutically in severe infections a combination antibiotic therapy, which is effective against most pathogenic members of the genital flora, is required. Short courses of perioperative prophylactic antibiotics are useful both in radical hysterectomy and with intracavitary irradiation.

Infections are still the most frequent peripartal complications. Very often they are nosocomial (hospital acquired) infections. Diagnosis and therapy of severe conditions may pose considerable problems. The most significant clinical factors in patient survival are the attentive surveillance and early recognition of the patient's disorder. The choice of antibiotics has to be done in consideration of the bacteriology of the vagina (endogenous infection). Removal of the infection site (uterus with or without adnexae) is the therapeutic procedure with the highest success rate in cases with sepsis or bacterial shock. Prophylaxis of infectious morbidity following caesarean section seems to be possible and advisable in patients with certain risk factors (labour, rupture of membranes, repeated vaginal examinations).

Your recent lead article on toxic shock and tampons (November 1, p. 1161) prompts me to report a case of pelvic infection and staphylococcal septicemia 8 days after the insertion of a Lippes loop. Pelvic infection is a recognized complication of IUDs; although there have been 2 reports of endocarditis occurring in susceptible patients following the insertion of an IUD, septicemia is rare. A previously healthy 31-year old married woman had a loop inserted at a family planning clinic. 3 days later she developed sweating, vomiting, confusion, and cough and during the following 48 hours became disoriented with hallucinations. She was referred to the hospital with suspected encephalitis and on admission was febrile (38.8 degrees Celsius) and stuporose but responded to simple commands. Blood pressure was 95/60 mmHg but there were no other abnormal signs. Hemoglobin was 12.2 g/dl, white blood count 4.0x109/1 (80% neutrophils), erythrocyte sedimentation rate 70mm in the 1st hour; cerebrospinal fluid normal. Chest x-ray examination revealed patchy consolidation in the upper lobes of both lungs and an electroencephalogram showed bilateral nonspecific abnormality. 3 blood cultures taken on admission yielded penicillin-resistant Staphylococcus aureus. She was treated with high-dose intravenous cloxacillin and 24 hours after starting the antibiotic had improved markedly and the IUD was removed. Culture from the coil and also from a high vaginal swab yielded Staph aureus with a similar antibiogram to that of the organism cultured from the blood. Subsequent recovery was uneventful, although repeat chest x-ray examination showed small abscess cavities in the upper lobes of both lungs. The patient was discharged 4 weeks after admission and serial chest radiographs have confirmed complete resolution of the pneumonia and abscesses. There is little doubt that this patients' septicemia with lung abscess formation and encephalopathy originated in the genital tract. The patient was both toxic and shocked but was different from patients with the recently described toxic shock syndrome in that her blood culture was positive for Staph aureus. The case provides another example of the importance of this organism as a cause of infection associated with the insertion of foreign bodies into or through the vagina.

Group B streptococci (GBS) are the major cause of neonatal pneumonia, sepsis, and meningitis. Steps considered to be important in the pathogenesis of this infection include colonization of the rectum and vagina of the mother, aspiration of GBS into the fetal lung during or just prior to delivery, and invasion of GBS into pulmonary epithelial cells. We have previously demonstrated that GBS can invade pulmonary epithelial cells both in vivo and in vitro. Adherence of GBS to epithelial cells may play an important role in colonization of the rectum and vagina and constitute a first step in invasion of pulmonary epithelial cells. Because GBS can both adhere to and invade epithelial cells, we have developed two assays for GBS adherence which measure cell surface and not intracellular bacteria. Using these assays, we were able to demonstrate specific adherence of GBS to pulmonary epithelial cells. Adherence levels were similar at 4 and 37 degrees C and for log- and stationary-phase bacteria. Physiologic conditions vary considerably between the rectum, vagina, and lung, and a range of conditions was therefore tested. Adherence was enhanced in hypotonic solutions, while magnesium and calcium had no effect on adherence at physiologic concentrations. In comparison with adherence at neutral pH, adherence was increased 6- to 20-fold at pH 4, which is the normal vaginal pH. Neither capsular polysaccharide nor lipoteichoic acid was important for adherence in these assays. Treatment of GBS with trypsin decreased their adherence by more than 75%, indicating that surface proteins play an important role.

The existence of combined rectal and vaginal prolapse is more common than the literature would suggest. This paper outlines a further development in the operative management which has been applied to 24 patients with this problem. All had had a hysterectomy and most had had in addition one or more vaginal repairs. The common mode of presentation was one of pelvic pain (19 patients), sometimes severe, crippling and intractable and some form of protrusion (14 patients), difficult or unsatisfied defaecation and rectal incontinence (9 patients). The vaginal prolapse which always involved the vault and usually involved the lower vagina was usually found to be incomplete and the rectal prolapse complete (but occult). The operative procedure essentially consists of a Wells type rectopexy which has a new modification in which the sling is extended to anchor the vaginal vault after correction of the enterocele by the abdominal approach. A vaginal repair is subsequently performed at the same operation where anterior or posterior vaginal prolapse persists. Important points in the procedure are the avoidance of sepsis (the vaginal vault is not opened during the procedure) and protection of the ureters by careful assessment of the lateral margins of the vaginal vault which is illuminated by transvaginal vault endoscopy. At this early stage operative morbidity has been minimal, relief of the pelvic symptoms has been most encouraging, but the length of follow-up is short (range 6-30 months, average 15.6) and long-term evaluation will be necessary as with all surgery for prolapse.

In the Netherlands a 34-year old pregnant women presented at the obstetrics and gynecology department of OLVG Hospital in Amsterdam with uterine bleeding. She was at 11 weeks gestation and had an IUD in situ. A vaginal ultrasound revealed that the pregnancy was intact so the physicians could not remove the IUD. She returned 12 days later because she was suffering from an incomplete spontaneous abortion. The physicians removed the IUD and performed an aspiration curettage. They did not administer antibiotics. 10 days after the operation the woman suffered worsening pain in the right thigh and leg and had difficulty walking, a fever, and general sickness. She was breathing very rapidly. Repeated vaginal ultrasounds revealed that she had retained the conceptus. The physicians prescribed respiratory support and antibiotics (claforan, gentamicin, and metronidazole). Blood culture indicated Staphylococcus aureus. Computer tomography revealed a retroperitoneal abscess at the level of the right iliopsoas muscle near the os ilium and the sacro-iliac joint. The physicians performed an extraperitoneal incision and drainage of the abscess and a repeat aspiration curettage. Staphylococcus aureus was isolated from all abscess samples, the conceptus, the cervix, the vagina, the urine, and the sputum. The physicians continued gentamicin and metronidazole treatment. They dismissed her after a complete recovery 16 days after the 2nd aspiration curettage. Possible complications of psoas abscess are sepsis, pulmonary embolism, hemorrhage, and bowel obstruction. Antibiotic prophylaxis in abortion curettage may prevent late sequelae, such as psoas abscess and pelvic inflammatory disease.

Escherichia coli K1 is the most common cause of gram-negative neonatal bacterial meningitis and septicemia. In an attempt to identify genetic markers in E. coli K1 that are associated with the capacity of the organism to cause neonatal meningitis, we used rRNA gene restriction patterns. E. coli strains isolated from the CSF of neonates with meningitis (n = 43) on two continents were compared to strains isolated from the blood of neonates with bacteremia who did not have meningitis (n = 29) and to isolates from the vaginas of asymptomatic pregnant women whose neonates remained without infection (n = 39). E. coli strains from CSF are genetically less heterogeneous than isolates from blood and the vagina: 44.2% of the CSF isolates belonged to only two types, whereas no more than two blood vaginal strains were of the same type. After HindIII digestion, a 14.9-kb rDNA-containing fragment was found in 81.3% of the strains from CSF vs. 28.0% of the isolates from blood and only 12.8% of the vaginal isolates (P = .001). Thus, genotyping might provide markers to identify organisms in the maternal vaginal flora that are highly likely to cause neonatal meningitis. This observation may have very practical implications for the early identification of these organisms in pregnant women and thus for the selective establishment of preventive measures per partum or for the early treatment of colonized neonates.

Melanoma is rare in Singapore with an age-standardised rate (ASR) of 0.4-0.8 per 100,000 per year. Thirteen patients with metastatic or locally advanced melanoma were referred to the Department of Medical Oncology, Singapore General Hospital between Feb 1991 and Nov 1993. Ten patients were given combination chemotherapy comprising carmustine (BCNU), cisplatin, dacarbazine (DTIC) and tamoxifen. The remaining 3 patients either rejected chemotherapy or were too ill to receive chemotherapy. Patient characteristics were as follows: there were 6 males and 4 females; age range 29-75 years; all were Chinese; sites of primary disease: extremities 8, retroorbital 1, vagina 1; sites of metastases: lymph nodes 6, skin 2, pulmonary 3, liver 1. All received the same combination chemotherapy comprising iv BCNU 150 mg/m2 q8wk, iv DTIC 220 mg/m2 x 3 days q4 wk, iv cisplatin 25 mg/m2 x 3 days q4 wk and tab tamoxifen 40 mg daily. There were 6 partial responses and no complete responses, giving a response rate of 60% with a median survival of 11.5 months. Three patients with sites of disease in the vagina, retroorbital region and metastatic liver disease had progressive disease despite chemotherapy and one died of treatment related sepsis. The 6 responders include those with metastases to the skin, nodes and/or lung. Treatment was generally tolerable. Two patients experienced delays of their subsequent cycles of treatment by 1-2 weeks due either to neutropenia and/or thrombocytopenia. This regimen is a fairly active combination against metastatic melanoma, particularly those with metastases to the nodes, skin and the lung. Those with involvement of other sites tend to respond poorly.

Eleven patients, 13 to 76 (mean, 40) years of age, had granulocytic sarcoma of the female genital tract (FGT) (ovary, seven cases; vagina, three cases; cervix, one case). In nine cases, the FGT involvement was the initial clinical presentation of the disease, and in the other two cases, the FGT involvement was discovered during a relapse of acute myeloid leukemia. The tumors ranged from 0.5 to 14 (mean, 7.5) cm in greatest dimension. Two ovarian tumors were bilateral, and three were green. Microscopic examination revealed a predominantly diffuse pattern of growth, but cords and pseudoacinar spaces were also present focally in several cases. Sclerosis was seen in five tumors and was prominent in one. Prominent myeloid differentiation was readily recognizable on routinely stained sections in three cases, whereas the neoplastic cells in the other cases were primitive with only rare eosinophilic myelocytes. All 11 tumors were positive for chloroacetate esterase, nine of nine were strongly and diffusely positive for lysozyme, eight of eight for myeloperoxidase, seven of seven for CD68, and six of six for CD43. Examination of bone marrow or peripheral blood performed after the diagnosis of FGT involvement revealed acute myeloid leukemia in three of five cases. Two of these patients died of disease, 1 and 16 months after the initial diagnosis, and the third, who received chemotherapy, is alive and free of disease 8 months after the initial diagnosis. One of the two patients with negative bone marrow had recurrent granulocytic sarcoma 30 months after diagnosis and died of sepsis 1 month later; no residual disease was noted at autopsy. The other patient is alive and free of disease 18 months after the diagnosis. One of the four remaining patients with primary FGT involvement who did not have a bone marrow biopsy died of leukemia 24 months later; no follow-up information is available for the other three patients. One of the two patients with a prior diagnosis of acute myeloid leukemia was alive with disease 26 months later; follow-up is not available for the second patient. The diagnosis was often difficult in these cases, the most common problem being distinction from malignant lymphoma, but carcinoma, granulosa cell tumor, and, rarely, other tumors were considered. Immunohistochemical and enzyme histochemical staining were useful in establishing the diagnosis, although suspicion of the diagnosis on examination of routinely stained sections was of paramount importance.
