The available hospital records of all pediatric patients diagnosed as having periorbital, preseptal or orbital cellulitis over a five-year period were reviewed and compared to previously reported series. Only two of 39 patients had orbital cellulitis. The 37 patients with preseptal cellulitis had two characteristic clinical presentations. Twenty-two children had local trauma, abscesses, insect bites, or impetigo as the inciting event for their cellulitis. Infection was usually caused by staphylococci or streptococci. In contrast, 15 children, 12 of whom were under 36 months, had associated upper respiratory tract infections and otitis. Haemophilus influenzae was the most commonly implicated pathogen and the children were at risk of bacteremia and metastastic infection. Determination of the location of the infection in the orbit and consideration of the clinical presentation of the patient with infection in and about the orbit are of assistance in choosing appropriate therapy. Young children who have upper respiratory tract symptoms in association with preseptal cellulitis should receive antibiotic coverage for Haemophilus.

Newborn infants with "early-onset" disease due to group B beta hemolytic streptococcus were studied over a 40-month period. Clinical presentations included asymptomatic bacteremia, mild transient illness, respiratory distress, meningitis, and overwhelming sepsis. Chronologically, 18 were ill at birth; 10 became ill after a symptom-free period; and four were asymptomatic. Sixty-six percent of the cases weighted less than 2500 grams, and 56% were born to mothers whose amniotic membranes were ruptured for over 20 hours. All 15 of the deaths occurred in low birth weight infants who were criticially ill from birth. A review of 128 consecutive deliveries of infants weighing under 2000 grams revealed 28 cases with prolonged ruptured membranes, and three of these 28 infants developed group B streptococcal infection. The infant of the colonized gravid woman in premature labor or with prolonged ruptured membranes is clearly at risk, and these results suggest that the management of "early-onset" disease should begin prior to delivery.

Forty-four patients with serious bacterial infections were treated with cefamandole in a dose 1--2 g every four to six hours. Thirty-two patients were cured and six were markedly improved. Three of six failures were due to superinfection with cephalothin-resistant microorganisms. The over-all bacteriologic response was 80%. In 12 of 13 patients with bacteremia the blood was sterilized. Ten of 14 patients with gram-negative bacillary infections responded to treatment. Six of these were due to cephalothin-resistant microorganisms, three of which responded. Fifteen patients who were treated had a history of penicillin allergy. There were no serious reactions although skin rash did develop. Phlebitis was uncommon.

Thirty-four patients undergoing elective colon resection or anastomosis received either intravenous cephalothin or cefamandole prophylactically and were observed for evidence of intraabdominal or wound infection, or both, postoperatively. The infection rates were 31 and 33 per cent, respectively. Infections were caused predominantly by cephalosporin resistant aerobes and anaerobes. All four bacteremias were caused by members of the B. fragilis group. The overall infection rate (32 per cent) and the frequency of anaerobic bacteremia (12 per cent) observed in this study were much higher than previously reported after cephalosporin prophylaxis for colorectal surgery.

Annualy in the USA, the estimated occurence of pneumococcal disease exceeds 500 000 cases of pneumonia (50 000 deaths), 1 200 000 cases of otitis media and 5 000 cases of meningitis. The pneumococcus remains the single most important pathogen which can cause pneumonia. When bacteremia accompanied pneumococcal pneumonia (one-fifth of these), the case fatality rate is approximately of 25% and exceeds 50% in individuals over 50 years of age. Most of the deaths (60%) occur within the first five days of illnesses, despite prompt antibiotic treatment of these patients. Emergence of pneumococcal strains with diminished sensitivity for penicillin, or resistant to tetracycline and other antibiotics is also a factor which lend increasing support to the concept that high risk patients should be protected from pneumococcal infection by immunoprophylaxis. A change of capsular types associated with bacteriemic disease has occured, in the USA, during the past three decades. The types 1 and 3 are less common than in the pre-antibiotic era, and the types 4, 8, 12, and 14 have become more prevalent. Infections with type 2, an epidemic type, have occured infrequently in the past 20 years. In the USA, at the present time, nearly four-fifths of bacteremic cases are associated with only 14 of the 84 pneumococcal capsular type ; in descending frequency : 8, 4, 1, 14, 3, 51, 12, 6, 56, 9, 19, 23, 5 and 20 (American system of nomenclature). The predominant capsular types of otitis media are : 1, 3, 6, 7, 14, 18 and 23. The polyvalent pneumococcal polysaccharide vaccine newly developed in the USA, is safe, antigenic and effective. Its widespread use can be expected to reduce the number of deaths attribuable to pneumococcal bacteremia.

Infections commonly occur in patients undergoing dialysis and have been related to diminished host resistance of uremic patients, the arteriovenous fistulas and bacteriologic contamination of dialysis fluids. The occurrence of four cases of bacteremia due to Pseudomonas, three of which were type 7, and the presence of this serotype in the dialysis fluids suggested an important association between infection and growth of bacteria in the fluids. Attempts to reduce levels of bacteria in the dialysis fluid were unsuccessful using dialysate free of glucose in clinical trial, despite in vitro studies demonstrating poor growth of Pseudomonas in this medium. A filter placed with the recirculating system was only partially successful. The second paper of this series traces the portal of entry of bacteria from dialysate to the blood through reutilized coils.

Netilmicin, a new semisynthetic aminoglycoside, was evaluated in the therapy of 33 episodes of infection in 30 patients. Eighteen patients had documented bacteremia. Infection sites included pulmonary, urinary tract and soft tissue areas. A complete bacteriologic and clinical cure rate of 85 per cent was achieved. No treatment failures occurred in the bacteremic group. Although netilmicin is less effective than gentamicin in vitro against Pseudomonas, it was clinically and bacteriologically effective. Netilmicin bacteriologic cures occurred in patients whose organisms were inhibited by 6.2 microgram/ml or less of netilmicin. Despite a uniform dosing protocol, a wide range of netilmicin serum levels was obtained. Adverse effects were limited to one case of transient nephrotoxicity and one Candida urinary suprainfection. Netilmicin appears to be an effective, safe agent for the therapy of serious infections.

Thirty-six febrile neutropenic episodes were treated by granulocyte transfusions in 33 children. Septicemia and mucous membrane ulcerations were most commonly associated with the fever. Infection cleared in 81% of the episodes, eight per cent ended in death from bacterial infections, 11% from nonbacterial infections or hemorrhage. The median number of polymorphonuclear leukocytes given was 1.1 X 10(10)/m2/transfusion. Two to twenty-eight (median 8.5) transfusions were given over 3--34 days (median 10.5). The source of cells (parental or random) and the method of collection did not seem to affect the outcome. None of the 23 patients whose marrow recovered during the transfusions died of bacterial infections. Infection cleared even without marrow recovery in 62% of the patients, but then only 25% lived for more than two months after clearing of sepsis. In a subgroup of patients with nonlymphoblastic leukemia on the same chemotherapy and antibiotic treatment protocol, 8/11 (73%) survived bacteremia when white cell support was available; only 2/11 (18%) of a historical control group survived when such support was not available. Granulocyte support appears to be a valuable tool in helping neutropenic patients overcome their infections or, at the very least, helping them survive long enough for normal marrow recovery to occur.

Mezlocillin, a new semisynthetic penicillin chemically related to ampicillin which is more active than carbenicillin against Ps. aeruginosa, B. fragilis and Strep. faecalis and which inhibits many Klebsiella, was evaluated in the therapy of 34 episodes of infection in 26 patients. Infection sites included pulmonary, urinary tract and tissue infections, including peritonitis. Seven patients had bacteremia. Clinical cures were achieved in 83 per cent and bacteria cures in 76 per cent of infections. Cure was achieved with mezlocillin in patients with infections caused by carbenicillin-resistant species. Adverse effects of therapy were minimal, one rash and one episode of reversible neutropenia. Serum and body flevels of susceptible organisms.uid levels were easily maintained above the inhibitory levels of susceptible organisms. Mezlocillin was a safe, well tolerated and effective antibiotic in the treatment of infections due to susceptible organisms.

Bacteremia due to a newly described species of Corynebacterium was identified in 12 patients during a two-year period. Infection occurred after a long period of hospitalization, extended granulocytopenia, and treatment with several antibiotics. Breaks in the mucocutaneous surfaces were the origin of infection in eight patients. All patients had evidence of colonization reported by cultures before infection. The invading organism caused death in three patients. Vancomycin hydrochloride was the antibiotic of choice. Corynebacterium is increasingly recognized as a primary cause of morbidity and mortality of patients with tumors.
