Streptococci are amont the most common bacterial pathogens physicians encounter in practice. Infections with streptococci continue to occur with significant frequency despite the general sensitivity of these organisms to a variety of widely used antibiotics. In newborn infants and other special patient groups, streptococci may produce fulminant and fatal sepsis (Table 1). In normal children and adults, infections usually are short term and often mild or unrecognized but with the possibility of resulting, unpredictably, in nonsuppurative complications some weeks or months later. Although scarlet fever has become an unusual and clinically attenuated disease, its rashless analog, streptococcal pharyngitis, presents thorny problems in the differential diagnosis of symptomatic patients and in the detection of subclinical infections. Erysipelas now is a rare disease, but recent studies have confirmed that streptococci often are the primary etiologic agent in impetigo, another type of skin infection--with peculiar bacteriologic and epidemiologic features. Infections with group D streptococci have always been a special case because of their frequent resistance to penicillin, and group B streptococci (also somewhat resistant) present special problems in the perinatal period. Streptococci may appear in unexpected places or guises (see Table 1). Thus, the modern physician has little reason to relax in his vigilance for and knowledge of streptococcal infections.

Groups A, B, C and G streptococci were cultured from 63 consecutive in-patients recruited between November 1987 and April 1988 and monitored until the end of July 1988. Chronic leg ulcers were present in 34 patients. Group G was found in 34 patients, 25 of whom had pyoderma and 3 had sepsis. Six of the patients had no signs of clinical infection, and treatment with antibiotics was therefore withheld. Recurrent phlegmon or erysipelas developed in 2 of 28 patients with clinical Group G infections. Erysipelas developed some 1-7 months later in 3 of the 6 patients who were not initially treated. No significant difference in severity or additional medical conditions was found between the patients with either Group G or Group A streptococci. In comparison, data on all streptococcal cultures at the Department indicated that Group G was isolated 2.6 times as often as Group A streptococci for the in-patients, compared with 1.1 for all patients seen. It is concluded that Group G streptococcal skin infections must be regarded with the same clinical vigilance as Group A infections.

Four patients with acute paracoccidioidomycosis, hypoalbuminemia, ascites and associated infections are reported. They have been admitted to hospital 35 times, 4 of them due to active paracoccidioidomycosis, 14 to associated infections, 14 to ascites, edema and diarrhoea and 3 to herniorrhaphy. Two of them recovered after sepsis and central nervous system, muscular and subcutaneous cryptococcosis. The remaining two died. One had infectious diarrhoea (S. flexneri), peritoneal tuberculosis and sepsis (S. epidermidis); the other had bacterial meningitis, erysipelas, beta-hemolytic Streptococcus sepsis and miliary tuberculosis. Their immunodeficiency was attributed to enteric protein loss and/or malabsorption and malnutrition and was recognized by reduced response to delayed hypersensitivity skin tests in four patients and hypogammaglobulinemia in three of them. The authors discuss the need for prospective studies to be carried out, aiming at the mechanisms involved in secondary infections. Alternatives for maintaining the patients' adequate nutritional state should be investigated, to guarantee proper immune response and thus the ability to control intervening infections in patients with juvenile paracoccidioidomycosis.

The diagnosis of erysipelas is usually made clinically. Features that help distinguish erysipelas are acute onset, erythema, warmth, edema, pain, fever, and isolated regional involvement with clearly demarcated margins. High ASO titers and response to penicillin therapy are reassuring. Simple uncomplicated erysipelas or cellulitis in adults can usually be treated on an outpatient basis. Extensive facial involvement with fever and a toxic appearance warrants hospitalization. Facial cellulitis or erysipelas in children, unless quite limited, requires hospitalization because of the high risk of Hemophilus influenzae infection and sepsis. Hospitalized patients should show visible signs of resolution and be afebrile for at least 24 hours prior to discharge. They should be maintained on oral antibiotic therapy at home for an additional 7 to 10 days.

The level of plasma fibronectin was measured to 20 patients suffering from erysipelas and 10 normal controls. Significantly low levels of plasma fibronectin were detected in the group of patients (134 +/- 7.4 g./ml) in comparison to the normal control group (352.6 +/- 42.9 g./ml) p less than 0.001. This could be of prognostic value and also of therapeutic one. Some centres have tried fibronectin replacement therapy in the treatment of critically ill patients with severe bacterial sepsis.

Trace elements like copper, zinc, iron and selenium have a significant influence on the function of the immune system. We studied plasma levels of trace elements in 53 patients with acute bacterial and viral infections. In bacterial infections (septicaemia, pneumonia, erysipelas and meningitis) the plasma concentrations of selenium, iron and zinc were decreased. Plasma copper was unchanged in patients with erysipelas, but increased in other types of bacterial infections. Although the patients with viral infections showed similar shifts of the trace elements as were observed in patients with bacterial infections, the changes were not as pronounced. A plasma selenium value below 0.8 mumol/l was found in only 6% of the patients with viral infections in contrast to 63% of the patients with septicaemia or 57% of the patients with pneumonia. Furthermore, in viral infections 60% of the zinc values were below the mean level of 12.8 mumol/l observed in healthy controls as compared with 90% of the values in patients with sepsis or 92% of the values in patients with pneumonia. The onset of change in trace elements occurred within a few days and persisted for several weeks. These changes seem to be non-specific and are independent of the agent causing infection. The different types of infections were followed by changes in most of the plasma proteins which are known to be associated with an inflammatory reaction. The changes in plasma proteins were most pronounced in patients with sepsis and pneumonia. Patients with sepsis having a high degree of inflammation did not show a positive correlation between the severity of the disease--as judged by plasma proteins--and the alterations of trace elements.

Fundamental and clinical studies on cefotetan (CTT), a new cephamycin antibiotic, were carried out under a joint study programme in pediatric field, and the following results were obtained. Pharmacokinetic study In 20 pediatric patients with normal renal function, weighing 15 to 48 kg, CTT was injected intravenously at 20 mg/kg in 3 to 5 minutes. The mean blood concentration of CTT was 215.6 micrograms/ml at 15 minutes after the end of injection, 90.7 micrograms/ml at 1 hour, 57.2 micrograms/ml at 2 hours, 33.9 micrograms/ml at 4 hours and 10.2 micrograms/ml at 8 hours. The half-life of the drug in the beta-phase, computed from the mean blood concentrations up to 8 hours postdosing, was 2.61 hours. The peak of the mean urinary excretion of cefotetan appeared in 0 to 2 hours after the injection and 36.5% of the dose was recovered in the urine. The mean excretion at 0 to 8 hours was 68.1%. Clinical study Clinical effects of CTT was evaluated in 285 patients with 287 diseases, since 1 patient had both pneumonia and erysipelas, and another both pneumonia and acute otitis media. Daily dosage of CTT ranged from 15 to 123 mg/kg, and 266 patients (93.3%) received the drug either 2 or 3 times daily. The clinical response was seen in 83.3% of the 6 cases with sepsis, 89.3% of the 122 cases with pneumonia with or without pyothorax, 96.2% of the 52 cases with either acute bronchitis or tonsillitis, 92.5% of the 67 cases with urinary tract infection and 92.5% of the 40 cases with other infections. The causative organisms were detected in 160 patients and the rate of complete disappearance was 80.6%. Out of 310 patients, side effects were seen in 9 cases, diarrhea in 8 (2.6%) and rash in 1 (0.3%). Abnormal clinical laboratory findings were seen in 24 cases, elevation of serum transaminases in 19 (7.8%), elevation of TTT and LDH in 1 (0.4%) and eosinophilia in 4 (1.6%). None of these cases showed serious side effects or abnormal clinical laboratory findings. From the above results, it is concluded that CTT is one of the useful drug for treatment of infections in pediatric field.

A fourteen-year-old girl with acute otitis media died from gram positive sepsis and toxic shock despite intensive treatment. The definitive bacteriological results showed positive cultures for both S. aureus and S. pyogenes serotype A. In vitro the bacteria produced the bacterial superantigens TSST-1, enterotoxin A, enterotoxin C (S. aureus) and erythrogenic toxin C (S. pyogenes). The patient presented with large flaccid sterile bullae on her chest and arms as well as necrotizing fasciitis. Tzanck test showed keratinozytes without necrosis and no inflammatory cells. Frozen-section and conventional skin biopsy specimens revealed subcorneal intraepidermal cleavage. These cytological and histological findings are those of staphylococcal scalded skin syndrome (SSSS) and differ from bullous erysipelas or toxic epidermal necrolysis (TEN). Therefore bacterial exotoxins are most likely responsible for the intraepidermal blistering in our case just as in SSSS. Bullae are an unfavorable prognostic sign in gram positive toxic shock syndrome. Both Tzanck test and frozen-section biopsy are easy to perform and useful in the early and rapid recognition of gram positive bullous toxic shock syndrome.

In the clinical classification of leprosy the diffuse nonnodular form belongs to the lepromatous subtype. In these patients only a diffuse cutaneous infiltration without nodules or plaques is seen. Although the cutaneous features can be difficult to identify, the reactional state in these cases may lead to a serious necrotizing vasculitis, known as Lucio's phenomenon. We describe two cases of Lucio's phenomenon triggered by erysipelas. The diagnosis of leprosy was established only after the immunologic reaction had occurred. Both patients were treated with steroids and thalidomide. In the second case, the bacterial infection led to sepsis and death. In at-risk patients with a necrotizing vasculitis, leprosy should be considered in the differential diagnosis.

A 7-month outbreak of 15 cases of postpartum sepsis with group A haemolytic Streptococci (GAS) was stopped when a carrier was identified. Comparing delivery dates with duty rotas revealed that the carrier had been present during delivery in 13 of the 15 cases. The epidemic GAS type, T3-13-B3264, was found in a carbuncle in her groin and in atopic dermatitis lesions behind her ears and on her eyelids. Thus, it was not the microbiological screening of staff that helped detect the carrier. The outbreak went unnoticed for 6 months, as no 2 cases were diagnosed by the same physician and 5 cases were diagnosed by different general practitioners. The main risk factors for infection were presence of the carrier relative risk (relative risk RR 47.8, 95% confidence interval (CI) 10.9-209.5) and suturing of episiotomy (RR 11.0; 95% CI 2.6-47.9). We recommend that a thorough epidemiological investigation should be carried out in every single case of GAS postpartum infection. Despite initial intravenous treatment with penicillin, 8 patients experienced > 15 recurring postpartum GAS infections, such as endometritis, wound infection, tonsillitis, erysipelas and Brodie's abscess. Eradication of GAS should be confirmed after completion of treatment.
