Corynebacterium sp. are found as normal flora in skin and mucosal sites. They have been isolated in empyemas, brain abscesses, blood cultures and ventricular shunts. About 9-10% of early-onset and 4-5% late-onset prosthetic valve endocarditis are due to different species of the so-called "diphteroids". A 30 year-old white female was admitted after 30 days with fever of undetermined origin. A mitral prosthesis had been fitted in 1977. On physical examination a protomesosystolic mitral murmur, petechiae, retinal hemorrhages and hepatosplenomegaly were detected. Laboratory tests showed 37% hematocrit, 14,800/mm3 white blood cells, 78 mm ESR, urinary sediment: less than 30/h.p.f. red blood cells. A new first-degree A-V block was detected. Blood cultures were negative. Due to persistent fever, progressive anemia, leukocytosis and new vegetations on echocardiogram, surgery was performed. A mitral valve ring abscess was found. Corynebacterium xerosis was isolated from surgical specimens. The strain was found susceptible to penicillin, ampicillin, oxacillin, ticarcillin, piperacillin, cephalotin, cefoxitin, cefoperazone, rifampin, gentamicin, amikacin, and norfloxacin. Studies with clindamycin, disclosed MIC and MBC = 0.25 mg/l. The patient received 1800 mg/day clindamycin for 4 weeks. Serum cidal studies showed a peak concentration 1/128 and a titre of trough 1/4. Negative control blood cultures were obtained. She has remained well for nine months after treatment. Corynebacterium sp. can cause "apparently" negative blood cultures. Blood samples should be incubated for more than 15 days before they can be considered negative. Almost 50% of previously described cases have been detected during the six months after cardiac surgery. Mortality has been high (48%).(ABSTRACT TRUNCATED AT 250 WORDS)

Immunological studies were carried out on two female patients with angioimmunoblastic lymphadenopathy (AIL). Both presented with fever, lymphadenopathy, hepatosplenomegaly, rash and apparent ampicillin hypersensitivity. During the active phase of the disease, cellular immunity was depressed and T cell blastogenesis induced by lectins was abnormal. In the first patient, a non-dialysable plasma factor was found that inhibited normal lymphocyte blastogenesis, the removal of which enhanced the activation of AIL lymphocytes. This inhibitory plasma factor was also observed in the second patient during relapse of the disease. The latter patient responded well to steroid and levamisole therapy, showing clinical remission and a return of in vivo and in vitro parameters of cellular immunity. Defective B cell regulation due to impaired suppressor function, followed by immunoglobulin overproduction, is suggested to occur in AIL.

A total of 592 children with clinical diagnosis of typhoid fever admitted to the Dr B. C. Roy Memorial Hospital for Children, Calcutta, India during the period between February 1990 and January 1992, were screened for Salmonella typhi by blood culture. S. typhi was isolated from 221 (37.3%) cases. The majority of the strains (92.3%) showed multi-drug resistant (MDR). They were resistant to chloramphenicol, ampicillin, tetracycline and trimethoprim-sulphamethoxazole. However, all the strains were uniformly (100%) susceptible to gentamicin, amikacin, furazolidone, norfloxacin and ciprofloxacin. Minimum inhibitory concentration of the antimicrobial agents against the resistant strains of S. typhi ranged between 200 and > 1600 micrograms/ml. Phage type 0 was most frequently encountered. The rate of isolation of S. typhi was more or less the same in all the pediatric age groups. The majority of the cases came from lower socio-economic classes with poor personal hygiene. Fever was the main presenting feature in all the cases. Other associated features of the MDR typhoid fever cases, who were uncomplicated during admission, were headache (36.0%), chill and rigor (23.2%), diarrhea (37.2%), anorexia (26.2%), vomiting (23.8%), cough (18.0%) and abdominal pain (19.8%). Hepatosplenomegaly was present in 42.4% cases. However, complications were less frequently encountered among the MDR typhoid fever cases who were uncomplicated during admission and treated as in-patients. Fourteen bacteriologically-confirmed MDR typhoid fever cases had jaundice and another 18 cases had an abnormal state of consciousness during admission. Four (2.0%) bacteriologically-confirmed MDR typhoid fever patients died during the period of observation.

A 24 year old woman living in the Mediterranean region of Turkey present with a three-month history of weight loss and irregular fever that was peaking at 40 degrees C with shivering. No definite aetiology could be identified in a local hospital. A bacterial infection had been suspected, but antibiotic therapy, at first with sulbactam-ampicillin and later with azithromycin, had no influence on the fever. Physical examination revealed an emaciated patient with fever (39 degrees C), pallor, and hepatosplenomegaly (spleen 9 cm and liver 5 cm palpable below the costal margin). No peripheral lymphadenopathy was present. The laboratory examinations are summarised in the table. Notably, a prominent increase of macrophages containing intracellular micro-organisms (figures 1 and 2) was seen in the bone marrow smears. The same micro-organisms were also identified within the Kupffer cells in liver biopsy.

Congenital syphilis (CS) is a public health burden in both developing and developed countries. We report two cases of CS in premature neonates with severe clinical manifestations; Patient 1 (gestational age 31 weeks, birth weight 1423 g) had disseminated idiopathic coagulation (DIC) while Patient 2 (gestational age 34 weeks and 6 days, birth weight 2299 g) had refractory syphilitic meningitis. Their mothers were single and had neither received antenatal care nor undergone syphilis screening. Both neonates were delivered via an emergency cesarean section and had birth asphyxia and transient tachypnea of newborn. Physical examination revealed massive hepatosplenomegaly. Laboratory testing of maternal and neonatal blood showed increased rapid plasma reagin (RPR) titer and positive Treponema pallidum hemagglutination assay. Diagnosis of CS was further supported by a positive IgM fluorescent treponemal antibody absorption test and large amounts of T. pallidum spirochetes detected in the placenta. Each neonate was initially treated with ampicillin and cefotaxime for early bacterial sepsis/meningitis that coexisted with CS. Patient 1 received fresh frozen plasma and antithrombin III to treat DIC. Patient 2 experienced a relapse of CS during initial antibiotic treatment, necessitating parenteral penicillin G. Treatment was effective in both neonates, as shown by reductions in RPR. Monitoring of growth and neurological development through to age 4 showed no evidence of apparent delay or complications. Without adequate antenatal care and maternal screening tests for infection, CS is difficult for non-specialists to diagnose at birth, because the clinical manifestations are similar to those of neonatal sepsis and meningitis. Ampicillin was insufficient for treating CS and penicillin G was necessary.
