In late October, 1974, Staphylococcus aureus postoperative wound infection was recorded in a nonhuman primate (Macaca mulatta) which had recently undergone surgical operation. Infection in a second monkey appeared approximately 2 weeks later, and a clustering of 6 cases appeared over the next 3-week period. The clinical spectrum included septicemia in 2 monkeys and skin infection at the surgical incision site of several others. Investigation revealed a uniform and consistent association of a phage group II S aureus strain characterized as 3A/55/71. This strain was also found to be enzootic among other postoperative monkeys sharing or having shared a common postsurgical care unit with infected monkeys. Epizootiologic studies indicated that this unusually virulent S aureus strain probably was introduced by an infected monkey which underwent surgery earlier in the month and that additional monkeys became infected by animal-to-animal transmission. After appropriate control sanitary measures were instituted, no new infections occurred.

In nine critically ill newborns, five of them with intractable diarrhea and four surgical patients, we administered a 5% crystalline aminoacids solution (AA) and glucose in sufficient amount to provide 120 cal times kg. in 24 hours. Six of them recovered after receiving parenteral alimentation for 3 to 15 days, gained weight during or after treatment and were discharged from the hospital in good conditions. Three died, one of them presented septicemia and two pneumonia and pulmonary infarcts. The solution used generated few metabolic alterations, the acid-base status remained within normal range and there were not important changes in the sodium and potassium serum concentrations. On the contrary, children with hyponatremia and hypokalemia at the beginning of the treatment, normalized these constants within the first hours, as diarrhea ceased. The most frequent complications were infiltrations and reaction of the surrounding tissue of the catheterized vein and local skin infection. Only one patient died of septicemia, possibly caused by this proceeding. In summary, parenteral alimentation though not free from risk, seems to be a useful proceeding when oral feeding is impossible or inadvisable. The utmost danger is septicemia. Metabolic changes are minimal and they do not mean a risk for child's life; nevertheless, there is a need for long term studies to bring up definite conclusions. The solutions in actual use are probably not the most physiological for the newborn. It is necessary to adequate them according to the new advances made on child nourishment during his first days of life.

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.

In a retrospective review of 53 patients, 58 episodes of infection due to Acinetobacter calcoaceticus var. anitratus (Herellea vaginicola) were studied. Although the organism is widely distributed in nature, it is of relatively low virulence since colonization is more frequently noted than infection and since most infections occur in patients subjected to the epidemiologic pressures common to nosocomial, gram-negative bacillary infection: prior antibiotic therapy; instrumentation and manipulation (e.g., endotracheal intubation, urinary bladder catheterization, arterial and venous cannulation); surgery; hospitalization, especially with residence in an intensive care unit; severe underlying disease, either systemic (e.g., chronic obstructive pulmonary disease, malignancy) or localized to the infected area (e.g., prior bacterial or aspirational pneumonia, trauma). Pneumonia was the most common infection due to A. calcoaceticus, and occurred only in patients with a tracheostomy or endotracheal tube in place. In over half the 25 patients, more than one lobe was involved and bronchopneumonia was the usual roentgenographic appearance. Cavitation (2 patients) and empyema formation (3 patients) were uncommon. The severity of acinetobacter pneumonia is reflected in the high mortality rate (44% overall, with a 36% mortality rate due primarily to infection). Tracheobronchitis due to A. calcoaceticus was less severe than pneumonia since no patients died primarily as a result of the infection. Urinary tract infections occurred in five patients, none of whom were ill and none of whom died. Urinary bladder catheterization was thought to be responsible for infection in three patients, and in at least four of the five patients infection was restricted to the lower tract. Wound infections were noted in six patients who had undergone surgery and were related to the presence of foreign bodies in the operative site in five of the patients. Surgical debridement and/or drainage of the infected area was the primary therapeutic measure employed in most cases. Only one patient died and this was a result of noninfectious causes. Skin infection due to A. calcoaceticus was seen in two patients, one of whom exhibited fulminant, fatal cellulitis and septicemia in the setting of pancytopenia. All nine patients with acinetobacter septicemia had received antecedent antibiotic therapy, and in all cases intravenous catheters were in place at the time bacteremia occurred. Clinically, seven of the nine patients were in shock. The mortality rate was 44% overall, with a 22% mortality rate due to infection. Although septicemia was thought to be "line-related" in five of the nine patients, serious post-bacteremic complications developed in three patients: prosthetic valve endocarditis, suppurative thrombophlebitis and subhepatic abscess.

An implantable drug delivery system will play an important role for patients who need chemotherapy or prolonged total parenteral nutrition in the future. We implanted 72 injection capsules in 74 patients who were undergoing aggressive chemotherapy or total parenteral nutrition programs. These capsules were implanted in different positions, including central access in 67 cases, peritoneal cavity in 1, hepatic artery in 2, portal vein in 1 and intrathecal space in 1. The actual median functional survival of the injection capsules was 12.3 months (range, 2 months to 4 years). The total cumulative puncture numbers were 1651 (range, 5 to 153; median 23). There was no unsuccessful instance in infusion or injection. To date, 27 patients still survive. The complication rate was about 7% including 1 sepsis, 1 skin infection, 1 catheter thrombosis, 1 dislodgement of reservoir and 1 catheter-reservoir disengagement, which were all corrected by a secondary operation without mortality. Patency of the Port-A-Cath system was maintained using a regular flushing schedule once every 30 days. The results of this study suggest that the implantable drug delivery system can provide a safe and reliable method for venous access or even arterious access in patients requiring intermittent or prolonged intravenous therapy.

During the 1980s there was a resurgence of serious Streptococcus pyogenes infections with complications, including rheumatic fever, sepsis, severe soft-tissue invasion, and toxic-shock-like syndrome (TSLS). We have investigated the suggested association between expression of a scarlet fever toxin, SPE A, and systemic toxicity, and the possibility that a new highly virulent clone of S pyogenes has emerged and spread world wide. We studied serotype M1 strains, the serotype most commonly associated with serious complications. 19 isolates from patients with sepsis, with or without TSLS, and 48 from patients with uncomplicated pharyngitis or superficial skin infection were subjected to restriction-enzyme digestion and electrophoresis; 56 isolates (19 serious, 37 uncomplicated disease) were then examined by hybridisation to an speA gene probe. 17 (90%) of the 19 serious-disease isolates had a characteristic ("invasive", I) restriction-fragment profile and were positive for the speA gene. Significantly lower proportions of the isolates from patients with uncomplicated disease had the I profile (21/48 [44%]; p = 0.0035) and speA (20/37 [54%]; p less than 0.001). These findings suggest that the strains from patients with serious disease are a unique clone, which became the predominant cause of severe streptococcal infections in the United States and elsewhere in the late 1980s.

Ecthyma gangrenosum due to Pseudomonas aeruginosa is a skin infection in which necrotic ulcerations surrounded by a red areola develop. The diaper area is the region most often involved in infants. Typically, ecthyma gangrenosum occurs in patients with septicemia and risk factors (chemotherapy, neutropenia). However, transient bacteremia or an infection confined to the skin may be the cause in some patients, with maceration in the diaper area and previous antibiotic therapy as risk factors.

Percutaneous gastrostomy was performed in 27 patients with ages ranging from 7 months to 18 years (mean, 8 years). Patient weights ranged from 4.7 to 73 kg (mean, 25 kg). Access to the stomach was planned and achieved with only fluoroscopic guidance. The technical success rate was 100%. Major procedure-related complications including death, sepsis, hemorrhage, peritonitis, or early tube removal did not occur. The minor complication of local skin infection occurred in six patients. Twenty-six patients (96%) tolerated tube feedings well. Mean follow-up was 184 days, and median follow-up was 103 days. At 30 days, 26 patients (96%) were alive. Percutaneous gastrostomy under fluoroscopic guidance is a safe and effective method of obtaining long-term nonparenteral nutritional access in pediatric patients.

Long-term experience with totally implanted catheter systems (TICS) is limited. We retrospectively evaluated the performance and long-term complications of TICS for intravenous infusion in cancer patients; 134 systems were implanted in 128 patients. The median duration of implantation was 144 weeks with 49 systems implanted for more than one year. Complications related to surgical factors included malposition of reservoir (2%), skin perforation or wound dehiscence (1.5%) and pneumothorax (less than 1%). Complications not related to surgical factors included: drug extravasation (1.5%), mechanical malfunction (1.5%), vein thrombosis (less than 1%), clotting of the reservoir or catheter (2%), skin infection (1.5%), and sepsis (less than 1%). The total complication rate was 13%. Most complications resolved spontaneously or with medical treatment and only 6 patients (4.6%) required re-implantation of a second system. We conclude that with long-term usage of TICS, the complication rate remains low, making it a safe and viable alternative for patients requiring long-term intravenous therapy.

An analysis was made of 695 cases of neonatal sepsis at Children's Hospital from 1982 to 1986. The incidence of neonatal sepsis and septicemia were 6.5 and 2.4 per 1,000 livebirths respectively. There were 178 cases of septicemia with onset during the first four days of life (early onset group) and 77 cases with onset after four days of life (late onset group). Both groups did not differ significantly in sex, birth weight and gestational age. Most of the cases had low birth weight and were premature. Pneumonia was the common associated infection. Omphalitis was found more frequently in the early onset of septicemia, whereas, NEC and skin infection were found more in the late onset group. Pseudomonas aeruginosa and Klebsiella pneumoniae were the major causes of infection in both groups. Staphylococcus was more common in late septicemia. No statistical difference in major complications was found between the two groups. Fatality rate in early and late septicemia was 32.6 and 28.2 per cent respectively.
