Acute bacterial meningitis still represents a therapeutic problem. Successful management depends on early administration of large doses of bactericidal antibiotics and adequate treatment of complications, i.e. shock, acute cerebral edema, consumption coagulopathy, convulsions and electrolyte disturbances. Meningitis caused by Neisseria meningitidis or Streptococcus pneumoniae should be treated with benzylpenicillin. If benzylpenicillin cannot be given, chloramphenicol has remained the best substitute. However, cefuroxime or ceftriaxone now seems to offer an alternative to chloramphenicol. The prevalence of beta-lactamase-producing Haemophilus influenzae strains is increasing and chloramphenicol has replaced ampicillin in the treatment of H. influenzae meningitis. Recent studies indicate that cefuroxime, ceftriaxone or moxalactam may be as effective as chloramphenicol in this type of meningitis. In neonatal meningitis, cefotaxime or moxalactam may constitute alternatives to the present regimens with ampicillin-gentamicin, gentamicin-chloramphenicol, cotrimoxazole or gentamicin. Promising results have also been obtained with cefotaxime or moxalactam in elderly patients with meningitis due to Gram-negative enteric bacilli. However, more extensive studies are needed to determine the role of the newer cephalosporins in the treatment of acute bacterial meningitis.

In five patients with purpura fulminans following meningitis, gangrene of the extremities developed. Four patients required amputations of the lower extremities and two patients of the upper extremities. The gangrene is caused by disseminated intravascular coagulation. In two patients epiphyseal damage and subsequent angular deformities developed. The orthopedic surgeon should be consulted early because aponeurectomy may save an extremity. Some method of temporary skin coverage should be considered at the time of initial debridement and aponeurectomy. Early skin grafts are frequently rejected because the extent of necrosis has not declared itself, necessitating further grafting, which results in multiple painful and unsightly donor scars. Stump problems due to less than satisfactory skin coverage, stump overgrowth, joint contractures, and epiphyseal damage are later complications.

26 children with meningococcal infections were studied to find out the relationaship between plasma and cerebrospinal fluid levels of endotoxin, the clinical outcome, the level of antigen in plasma and cerebrospinal fluid, and indices of complement activation and disseminated intravascular coagulation. No association was found between endotoxin levels and the other factors. A high cerebrospinal fluid antigen level in patients with meningitis was associated with a poor prognosis.

There are occasional reports in medical literature of peripheral gangrene and subsequent extremity amputation following systemic infection. Although the authors of these case reports speculated that the gangrene was due to septic embolization, pathologic study of the amputated tissue failed to reveal evidence of septic emboli. In reviewing reports of amputation following scarlet fever, varicella, pneumococcemia, and appendicitis, we found cases with clinical, hematologic, and pathologic evidence of disseminated intravascular coagulation (DIC). We describe 2 patients who required extremity amputation following an acute, systemic infection: transmetatarsal and Lisfranc amputation following meningococcal meningitis and bilateral below-knee amputation following pneumococcal meningitis. Both of these patients had clinical, hematologic, and pathologic evidence of DIC. Following amputation, both of these patients had significant problems with skin healing and prosthetic fitting. The presence of an acute systemic bacterial or viral infection, coagulation abnormalities and pathologic tissue indicative of DIC, and skin lesions of the extremities progressing to dry gangrene and ultimately requiring bilateral amputation are the key clinical features of this syndrome. We conclude that DIC is a major pathophysiologic mechanism responsible for peripheral gangrene following systemic infection.

A therapeutic trial of transfusions with polymorphonuclear leukocyte concentrates was performed in newborn infants with bacterial sepsis proven by blood culture. With each transfusion, 20 ml/kg of a preparation obtained by continuous flow filtration leukapheresis, and containing 0.5 to 1 x 10(9) WBC, with less than 6% lymphocytes, was administered. Twenty newborn infants with sepsis received from 2 to 15 PMN transfusions. Results were compared with findings in 18 newborn infants with sepsis admitted during the trial period, and not treated because of unavailability of the PMN preparation (Group B). Infants with fulminant illness were excluded from both groups. Groups A and B were similar with respect to clinical characteristics and to etiology (in the majority cases a highly antibiotic-resistant Klebsiella). The mortality rate was significantly lower in Group A than in Group B in the whole series (10% vs 72%, P < 0.001), and also in the subgroups with birth weight equal or below 1,500 gm (10% vs 91%, P < 0.001). Major complications and associated conditions (i.e., necrotizing enterocolitis, meningitis, pneumonia, peritonitis, osteoarthritis, disseminated intravascular coagulation) were observed in 12 patients of Group B, and in only three infants of Group A. Untoward effects attributable to PMN transfusions were never observed. PMN transfusion was a highly effective therapeutic tool in our population of infected newborn infants.

From 1980-1990 245 immunocompetent patients were admitted to The Department of Infectious Diseases, Marselisborg Hospital with purulent meningitis or meningococcal septicaemia. The clinical diagnosis was established by clinical examination and by neutrophil pleocytosis. The aetiological diagnosis was established by demonstration of bacteria in the cerebrospinal fluid by microscopy or culture and by blood culture. Clinical signs of disseminated intravascular coagulation (DIC) or demonstration of meningococcal antibodies (MAT) in serum were considered diagnostic for meningococcal disease. The group comprised 120 males and 125 females aged 0-90 years. One hundred and eleven (45%) had meningococcal disease, 69 (28%) had pneumococcal meningitis, and 20 (8%) had H. influenzae-meningitis. Other aetiologies occurred in one to six cases. No aetiology could be established in 25 (10%) patients. Patients with meningococcal and pneumococcal disease were treated with monotherapy with high doses of penicillin, and H. influenzae-meningitis was treated with ampicillin. In patients with meningitis of unknown aetiology penicillin was used, except in children below the age of five where ampicillin was used. In patients with meningococcal disease the mortality was 5.4%, and 17% developed sequelae. In pneumococcal meningitis the corresponding figures were 13% and 17%, and in H. influenzae-meningitis 0% and 5% respectively. Among 20 patients with other aetiologies one patient (5%) died, and eight (40%) developed sequelae, whereas one patient (4%) died, and one (4%) developed sequelae in the group with meningitis of unknown aetiology. No ampicillin-resistant H. influenzae-strains were demonstrated. We suggest that monotherapy with betalactam-antibiotics is still a valuable treatment for meningitis in Denmark.

Twenty-five patients were admitted to two hospitals in Hong Kong for Streptococcus suis infection between 1984 and 1993. Among them, 15 (60%) had an occupational exposure to pigs or pork, and four had a clear history of skin injury up to 16 days before admission. Examination of the cerebrospinal fluid of 21 patients confirmed the presence of meningitis in every case; the remaining four patients who did not have lumbar punctures had each presented with arthritis, bronchopneumonia, endocarditis and pyrexia without neck stiffness. The only fatality was a patient admitted in septicaemic shock with evidence of meningitis and disseminated intravascular coagulation. Of the 24 survivors, 16 (67%) acquired varying degrees of hearing loss as a result of meningitic involvement. All the isolates of S. suis were sensitive to penicillin or ampicillin, which was used alone or in combination with other antibiotics for every patient. Two patients had a relapse of symptoms when penicillin was stopped, but were successfully treated after the antibiotic was resumed for a total of 6 weeks. Over 100 cases of S. suis infection have been described previously, with a geographic distribution heavily biased towards Northern Europe and Southeast Asia. Lack of awareness of this unique zoonosis may be a reason why it is not diagnosed more readily elsewhere.

Tuberculosis has been increasing especially in urban areas and in immunosuppressed patients; however, the incidence and factors associated with tuberculosis in OLT patients are unknown. Five of 550 patients who underwent OLT at the Mount Sinai Medical Center during a 5-year period were noted to have tuberculosis. The mean age of the patients was 49.2 years; there were 3 males and 2 females and 3 were foreign born. One of 5 had a prior history of tuberculosis. Tuberculin skin tests performed before transplant revealed 1 positive and 2 anergic reactions. The preoperative chest x-ray revealed apical fibrosis in 2 patients and bilateral apical disease with a nodule in 1 patient. Tuberculosis developed from 2 to 57 months after surgery in 4/5 patients. One had miliary lesions of the peritoneum discovered at the time of OLT. One patient had recent contact with a patient with pulmonary tuberculosis. At presentation, fever was present in 4 of 5 patients, pulmonary lesions in 3 patients, meningitis in 2; during hospitalization, 1 had a liver abscess and disseminated intravascular coagulation and peripheral gangrene. Lymphocytosis was noted in the pleural (1), peritoneal (1), and cerebrospinal fluid (1). Acid-fast smears were positive in bronchoalveolar lavage fluid (1), peritoneal isolates (1), and liver biopsy (1). All patients had positive cultures for Mycobacterium tuberculosis. These isolates were all sensitive to isoniazid, streptomycin, rifampin, ethambutol, and pyrazinamide. Four of 5 patients were treated with isoniazid and rifampin, 2 received pyrazinamide, 2, amikacin, 2, ofloxacin, and 2, ethambutol. Three of 5 patients are doing well on antituberculous therapy and 2 expired with tuberculosis as the cause of death. In OLT patients with unexplained fever, tuberculosis including extrapulmonary and disseminated disease should be considered since the mortality rate is very high. Liver transplantation can be performed in the presence of active peritoneal tuberculosis with the use of judicious antituberculous therapy. The role of preventive therapy is controversial, though use in certain high risk patients is suggested.

Enterovirus infection has been recognized as one of the most common viral infections in the perinatal and neonatal periods. It frequently leads to significant mortality. One fatal case of neonatal enteroviral infection was experienced in last year. The patient was a one-day-old male, presenting with neonatal sepsis. He has a biphasic illness, first with a mild febrile prodrome then followed by severe systemic involvement, with meningitis, myocarditis, hepatosplenomegaly and disseminated intravascular coagulation. All bacterial cultures were negative, but the rectal swab isolated enterovirus. The echocardiogram revealed depressed cardiac function, and he finally expired at the age of 10 days. The autopsy findings supported the diagnosis of perinatal enteroviral infection (coxsackievirus B infection was highly suspected). Clinically, if a neonate presents as sepsis, but has the following conditions, enteroviral infection should be considered: (1) negative bacterial cultures; (2) multiple organ involvement; (3) proven enteroviral infection in the same nursery or ward; (4) a mild febrile illness in the mother within the last antepartum 10 days or the first postpartum 5 days; (5) any family members with fever or signs of upper respiratory infection within 15 days before delivery.

Thirty-nine Danish cases of Capnocytophaga canimorsus septicemia were reviewed to determine the clinical course of this infection. The cases of septicemia were related to recent dog bites or other close contact with dogs. The period from the bite to the onset of symptoms ranged from 1 to 8 days. The mean age of the patients was 59.1 years (range, 28-83 years). Underlying conditions included previous splenectomy and alcoholism. Thirteen patients had previously been in good health. Common initial symptoms were fever, malaise, myalgia, vomiting, diarrhea, abdominal pain, dyspnea, confusion, headache and skin manifestations. Disseminated intravascular coagulation developed in 14 patients, meningitis in 5, and endocarditis in 1. Twelve of the patients died. All patients except two were treated with penicillin or ampicillin. Five patients had received antibiotics prior to admission. Attention should be drawn to C. canimorsus septicemia in cases of febrile illness following dog bites or contact with dogs, as well as those involving previously healthy persons. The incidence of this condition in Denmark is estimated to be 0.5 case per 1 million people per year.
