Septicemic disease occurred in 49 of 126 pigs several days after being transported 80 km. All affected pigs died. The main changes in acutely affected pigs were skin discoloration, pulmonary edema, arthritis, meningitis, and renal glomerular thrombosis. In peracute cases, gross findings were minimal. Haemophilus parasuis was isolated from multiple organ sites in most affected pigs. Haemophilus parasuis was isolated from nasal swab specimens from 17 of 20 clinically normal pigs on the farm of origin. Fatal acute septicemia was reproduced in 2 pigs by intravenous or intratracheal exposure to an isolant of H parasuis obtained from 1 of of the 49 fatally affected pigs. Aerosol exposure of 5 pigs resulted in mild pneumonia in 4 pigs and severe pneumonia, pleurisy, pericarditis, and terminal septicemia in 1 pig.

Retrospective evaluation of the occurrence of septicemia and meningitis in 200 children who had staging laparotomy iwth splenectomy for Hodgkin's disease revealed 20 episodes occurring in 18 children. Symptoms were usually fulminant; only 10 of these patients survived their episode. Infections occurred eight days to three years after splenectomy. Adolescents, as well as younger children, were affected; half were older than 10 years of age. Leukopenia was not a major factor in onset or survival since the average white-cell count was 12,000 in both survivors and children who died. Pneumonococcus accounted for 50 per cent, and streptococcus for 15 per cent of infections; there was one episode each of Haemophilus influenzae and meningococcus; in 25 per cent, no organism was isolated. Predominance of penicillin-sensitive organisms and high mortality suggest that penicillin prophylaxis and the protection offered by bacterial vaccines should be evaluated in children with Hodgkin's disease whose staging laparotomy includes splenectomy.

Five bulls were inoculated intranasally with a live culture of Hemophilus somnus originally isolated from a clinical case of Hemophilus septicemia. Preinoculation and postinoculation blood samples were taken at weekly intervals for nine weeks for measuring complement fixation titers and daily postinoculation temperatures were taken for one week. Three animals had transient fever and slight lethargy was observed in two animals had a transitory rise in complement fixation titers in the second to fifth weeks postexposure while one animal which had been seronegative on preinoculation testing produced little serological response to the organism. The experiment demonstrated that the nasal instillation of young cattle using an originally pathogenic H. somnus isolate is capable of stimulating only transitory complement fixation antibody titer.

Although Hemophilus influenzae is a common cause of meningitis, other members of the Hemophilus genus are rarely the infecting organism. Of 56 cases of meningitis due to Hemophilus species obseved at one hospital in the period 1970-74, 53 were due to H. influenzae and 3 to H. parainfluenzae. In the cases of H. parainfluenzae meningitis the clinical picture was complicated by associated sepsis, and therapy with ampicillin was not entirely satisfactory.

Two newborns had hematogenous pyarthrosis due to Haemophilus influenzae. One infant had signs of sepsis and dactylitis involving several fingers and toes. She also developed a soft tissue abscess, meningitis, and a septic hip, and was found to be infected with a nontypable organism. In the second infant, a shoulder traumatized at birth became infected with a type b strain. In both cases, the patients were successfully treated, but delays occurred in selecting the optimal therapeutic agent because of failure to appreciate that Haemophilus may cause systemic infection in the newborn. In the first infant the source of the infection was identified as the mother's endocervical canal. This patient is also of interest because in contrast to previous reports of Haemophilus infection in the newborn, bactericidal activity was present in the maternal serum.

This study was undertaken to determine whether the terminal complement components (C3-9) are involved in the nonimmune host defense against Haemophilus influenzae type b septicemia and meningitis. Using cobra venom factor, infant rats were depleted of C3 and C5. After intranasal challenge with H. influenzae type b, the complement-depleted rats developed a greater incidence and magnitude of bacteremia and a higher mortality rate. In contrast to the effects on bacteremia, complement depletion did not directly influence either the occurrence of meningitis or bacterial multiplication within the cerebrospinal fluid. These experiments provide evidence that the complement system may be an important mechanism of natural immunity to H. influenzae type b.

The aim of the study was to evaluate the relationship between germs found in samples systematically taken in the organ donors and germs found in the corresponding recipients in the 8 post-operative days. The 100 brain-dead patients received oxacillin (2g every 4 hours) when the bacteriological samples were taken. 41% of the donors were germ carriers. The germs were mainly located in the respiratory track (Staphylococcus aureus meti-S (34%) and Hemophilus (29%)). Among the 86 patients harvested, 40 donors were germ carriers and gave 132 organs, 46 donors were not germ carrier and gave 151 organs. The comparison between these two groups showed no difference. Assessment of infection occurring in organ recipient in the 8 post-operative days (germ, location, evolution) showed no difference, whether organs were removed from germ carrier donors or no. Comparison between the germs found in germ carrier donors and those found in recipients with sepsis showed a similitude in three cases (2.2%). In the other cases, there is no relationship between the germs found in the donors and post-operative sepsis in the recipient.

Wandering spleen is an unusual entity, occurring in both sexes and at any age, but is more frequent in women of reproductive age and in children. Wandering spleen is probably most often a result of congenital anomalies of development of the dorsal mesogastrium, but acquired factors may have a role in certain instances. Patients present most commonly with an asymptomatic mass, mass and subacute abdominal or gastrointestinal complaints or with acute abdominal findings. Clinical diagnosis can be difficult, but noninvasive imaging procedures, such as sonography, nuclear scintigraphy, computed tomography and magnetic resonance imaging are usually diagnostic. Laboratory tests are usually nonspecific, but may occasionally reveal evidence of hypersplenism or functional splenia. Symptoms may remain limited or absent for long periods of time, but complications related to torsion or compression of abdominal organs by the spleen or the pedicle are quite common. Splenomegaly is usually a result of torsion of the pedicle and splenic sequestration. Significant morbidity and mortality rates seem to be considerably less than described in 1933 and limited primarily to patients presenting initially with acute abdominal findings. Management recommendations have varied, but recognition of a significant risk of postsplenectomy sepsis supports a conservative approach. Patients with limited symptomatology may be medically managed until they exhibit worsening symptoms indicating progressive splenic torsion or gastrointestinal compression. Detorsion and splenopexy may be considered a reasonable surgical option even in patients presenting with acute abdomen, if there is no evidence of infarction, thrombosis or hypersplenism. Splenic preservation is especially recommended in extremely young patients who are at particular risk for postsplenectomy sepsis. However, it should be noted that follow-up evaluation data on splenopexy patients are notably lacking. Splenectomy is ideally reserved for patients presenting with acute abdomen and splenic infarction or thrombosis or with hypersplenism and patients in whom splenopexy is technically unfeasible. Subtotal splenectomy and splenic autotransplantation may be of limited value. Pneumococcal, Hemophilus and meningococcal vaccines are indicated before elective splenectomy and shortly after nonelective splenectomy. Antibiotic prophylaxis is recommended for those at particular risk. Prospective studies are unlikely, but extended follow-up information on patients already reported, particularly those managed expectantly or with conservative surgical measures, is needed.

Pharmacokinetic and clinical evaluations in pediatrics were made on meropenem (SM-7338, MEPM), a new parenteral dehydropeptidase-1 stable carbapenem used without any inhibitors, at 33 medical institutions. The results are summarized as follows. 1. Pharmacokinetic studies. MEPM at a dose of 10, 20, or 40 mg/kg was administered to 53 children by 30-minute drip infusion. Peak plasma concentrations (Cmax's) and plasma half-lives (T1/2's) of these doses were 28.5, 47.2 and 130.0 micrograms/ml, and 0.80, 0.93 and 0.94 hours, respectively. A clear dose response was observed in Cmax's and T1/2 values were quite similar to those observed in adults. In the first 6 hours after administration, 54.4 to 68.1% of the administered drug was recovered in urine. The cerebrospinal fluid (CSF) levels of MEPM in patients with purulent meningitis were 0.13 microgram/ml at a dose of 6 mg/kg, and 0.64 to 4.22 micrograms/ml at a dose of 29 to 44 mg/kg within day 4 of onset. The penetration rate of MEPM showed an intermediate value among those for other cephalosporin antibiotics. 2. Clinical study. Clinical efficacies of MEPM were evaluated in 389 cases. The most common doses used were 10 to 20 mg/kg/once, 2 to 3 times a day. The maximum dose was 173 mg/kg/day q.i.d. MEPM gave "excellent" or "good" responses in 242 (97.6%) out of 248 cases in which causative organisms were documented and in 134 (95.0%) out of 141 cases in which causative organisms were not identified. Clinical efficacy rates were 100% in 11 patients with purulent meningitis, 85.7% in 7 with septicemia, 98.8% in 173 with pneumonia, and 100% in 65 with UTI. Bacteriologically, 260 strains (96.7%) out of 269 strains were eradicated by MEPM treatment. Eradication rates were 89.2% for Staphylococcus aureus (37 strains) and 100% for Streptococcus pneumoniae (35 strains). The overall eradication rate for Gram-positive bacteria was 94.6%. Among Gram-negative bacteria, 98.3% out of 172 strains were eradicated. The eradication rate of Haemophilus influenzae (73 strains) was 98.6% and Pseudomonas aeruginosa (11 strains) was 90.9%, and all of Branhamella catarrhalis (15 strains), Escherichia coli (42 strains), and Klebsiella pneumoniae (6 strains) were eradicated. Out of 84 cases for which previous antibiotic therapies of 3 days or longer were not successful, MEPM gave "excellent" or "good" responses in 77 cases (91.7%) and excellent bacteriological responses (95.7%).(ABSTRACT TRUNCATED AT 400 WORDS)

Pharmacokinetic, bacteriological and clinical studies were performed on panipenem/betamipron (PAPM/BP) in children. The results are summarized as follow: 1. Twelve patients with various bacterial infectious diseases were treated with PAPM/BP. Each dose was 20 mg/20 mg/kg, administered 3 times daily, in 30-minute intravenous drip infusion. Treatments were continued for 5-22 days. Clinical efficacies of PAPM/BP in 12 patients with bacterial infections (1 with suspected sepsis, 5 with pneumonia, 1 with acute maxillary sinusitis, 2 with acute otitis media, 1 with cervical abscess and 2 with urinary tract infection complexed type) were evaluated as excellent in 7, good in 4 and fair in 1, with an efficacy rate of 91.7%. Seventeen causative organisms found in 10 patients (Haemophilus influenzae in 4, Branhamella catarrhalis in 3, Streptococcus pneumoniae in 2, Pseudomonas aeruginosa in 2, Staphylococcus aureus in 1, alpha-Streptococcus in 1, Corynebacterium sp. in 1, Peptostreptococcus micros in 1 and Klebsiella pneumoniae in 2) were eradicated except 2 strains (S. aureus and P. aeruginosa) from 1 patient (patient No. 2). No adverse reactions were observed in any of the 12 patients. 2. MICs of PAPM were examined against 22 clinical isolates (H. influenzae 5, B. catarrhalis 3, alpha-Streptococcus 3, S. pneumoniae 2, Corynebacterium sp. 2, S. aureus 1, P. aeruginosa 1, P. micros 1, Enterobacter cloacae 1, Escherichia coli 1, Group D Streptococcus 1 and Staphylococcus epidermidis 1) from children with bacterial infections. PAPM showed a good antibacterial activity comparable to the activity of cefoperazone (CPZ) against S. pneumoniae strains relatively tolerant to penicillins. However, the activity of PAPM against H. influenzae was somewhat weaker than that of CPZ. 3. Pharmacokinetic studies.(ABSTRACT TRUNCATED AT 250 WORDS)
