During a six-month period, 187 inpatients had bacteremia associated with community-acquired infection and 91 patients had bacteremia from a nosocomial infection. The most frequently identified sites of infection in both types of bacteremia were the respiratory and urinary tracts. Escherichia coli and Diplococcus pneumoniae were the organisms most frequently isolated from cultures of patients with community-acquired bacteremia, and E coli, Staphylococcus aureus, and Klebsiella were most frequently isolated from patients with nosocomial bacteremia. Bacteremic nosocomial infections were related to urinary catheters, respiratory and intravenous therapy, or hyperalimentation in 32 of the 91 cases. Even assuming the unproved hypotheses that rigid adherence to current guidelines would prevent all of these procedure-related cases, 59 cases of bacteremia would still have occurred. This emphasizes the need for further research into prevention of nosocomial infection.

Bacterial and fungal growth in 10% soybean oil emulsion (Intralipid) and 5% fibrin hydrolysate in 5% dextrose was studied at 4, 25 and 37 degrees C. Staphylococcus aureus, Streptococcus pyogenes, Str. fecalis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli and Candida albicans were grown in broth at 37 degrees C, diluted in saline and inoculated into each of the two preparations as well as a mixture of the two. Growth was measured at 24, 48 and 72 hours. In 10% soybean emulsion, all bacteria except S. pyogenes multiplied, but in fibrin hydrolysate-dextrose solution the only organism of those studied to grow was S. aureus. In the hydrolysate-dextrose-lipid mixture, all organisms multiplied except S. pyogenes and P. aeruginosa. C. albicans grew in all solutions tested. While at 4 degrees C, organisms did not multiply. The fibrin hydrolysate-dextrose solutions given by infusion into a central vein for hyperalimentation have been shown to support predominantly fungal growth, and contamination of the solution and ultimately of the indwelling catheter is a constant hazard. Because both bacteria and C. albicans grew equally well in 10% soybean oil emulsion, its use as a caloric source when infused into a central vein may increase the occurrence of sepsis. When this emulsion is used to provide essential fatty acids or calories, it should be given via a peripheral vein, so that a central catheter will not be contaminated.

Several pre- and post-natal factors possibly important in determining which infants will develop necrotizing enterocolitis (NEC) and which of these infants will die with this disease were prospectively studied in 1976 in 11 infants with radiographic or pathologic evidence of the disease from 12 institutions in the United States and 111 weight-matched, institution-matched control infants. By multivariant discriminant analysis, the authors idenfitied 10 independent significant determinants of NEC and 10 determinants predictive of a fatal outcome among case infants. Determinants of NEC were: Apgar score deterioration; presence of a patent ductus arteriosus; maternal receipt of anesthesia during delivery; infant not treated with parenteral gentamicin before the onset of disease; infant receipt of 10% dextrose solution; treatment of mother with antibiotics during pregnancy; hyperalimentation or gavage feedings; premature rupture of membranes. Important morbid events among cases included red blood cell transfusions, gas in the portal system, premature rupture of membranes, abdominal distension, isolation of Klebsiella organisms from the blood, surgery, prolonged perinatal oxygen requirement, and lower Apgar 2 score. Attempts to modify preventable risk factors may decrease the incidence (2.4 cases per 1000 live births) and case fatality (41%) documented in this study.

We examined the clinical features and significance of pathogenic microbes isolated from sputum and blood of patients with lung cancer during anti-cancer therapy. Pathogenic bacteria were more likely to be isolated from patients with episodes of fever than from afebrile patients. The major species of bacteria isolated from sputum were Staphylococcus aureus, including methicillin-resistant strains, and Gram-negative bacilli, which are known to be frequently involved in hospital-acquired infections. The presence of an indwelling central venous catheter for intravenous hyperalimentation was an important risk factor for the development of a febrile episode, which indicates that bacteremia was a major cause of fever. In one quarter of the blood cultures from the patients with persistent fever, various species of pathogenic microbes were recovered, one-third of which were fungi. Bacteriological examinations done before and after the introduction of granulocyte-colony stimulating factor (G-CSF) revealed that strains of Klebsiella spp. decreased and those of methicillin-resistant S. aureus increased. There was no firm evidence that G-CSF decreased the incidence of episodes of fever. However, remains G-CSF may a allow the dose intensity of anti-cancer agents to be increased, which would lead to severe leukocytopenia. However, more detailed investigation is needed to clarify the role of G-CSF against bacterial infection during anti-cancer therapy.

We report a case of systemic sclerosis (SSc) complicated with benign pneumoperitoneum without apparent pneumatosis cystoides intestinalis (PCI). A 43-year-old woman was admitted to our hospital because of prominent abdominal distension in April 1997. Raynaud's phenomenon has been detected since 1991. She was suffering from recurrent diarrhea, constipation, and subileus. The diagnosis of SSc was made in 1996 based on the sclerosis in her face, forearms, and chest, and hypomotility of the esophagus. On admission, she presented no signs of peritoneal irritation. The laboratory data revealed that white blood cell count was 7,400/mm3 and C-reactive protein was 0.1 mg/dl. Chest and abdominal roentgenograms showed massive free air under the diaphragm, dilatation of small and large intestine, and air-fluid level. PCI was not apparent. Pneumoperitoneum was improved after four weeks with intravenous hyperalimentation. But she presented recurrent severe diarrhea and high fever whenever she tried to take food orally. Klebsiella pneumoniae was proved in her jejunal juice by bacteriologic examination. Intravenous prostaglandin F2 alpha and oral fosfomycin calcium intake made her condition better. Benign pneumoperitoneum without PCI is rarely reported in the patients with SSc. In her condition, weakness of intestinal wall, hypomotility of intestine, unusual bacterial overgrowth, and elevated intraluminal pressure made intraluminal gas go through the wall of the fragile intestine of SSc. As operation of intestine of SSc usually cause miserable outcome, pneumoperitoneum accompanied with SSc even if PCI is apparent or not must be treated with conventional manner while there is no signs of peritoneal irritation.

Prader-Willi syndrome is a rare genetic disorder associated with impaired body composition, hyperphagia, and excessive weight gain. Strict dietary restrictions from an early age is crucial to prevent or delay the early onset of obesity, which is the main driver of comorbidities in these patients. The aim of this study was to identify dietary and gut microbiota components closely linked to weight status of these patients. We studied a cohort of children and adolescents with genetic diagnosis of Prader-Willi syndrome (N = 31), in which we determined adiposity by Dual-energy X-ray absorptiometry (DXA) and dietary composition with 4-day food records. Furthermore, we obtained fecal samples to assess microbiota composition by 16S sequencing. Multivariate regression models showed that body mass index standard deviation score (BMI-SDS) and body fat mass were directly associated with saturated fat intake and meat consumption, and inversely associated with fruit consumption. Furthermore, the gut microbiome from normal weight patients was characterized by higher phylogenetic diversity compared to those overweight or obese, with differential abundance of several genera, including Alistipes, Klebsiella, and Murimonas. Notably, Alistipes abundance was inversely correlated to adiposity, lipid and glucose homeostasis parameters, and meat intake. Our results suggest that limiting meat and increasing fruit intake might be beneficial for body weight management in children and adolescents with Prader-Willi syndrome.
