Clinical nutrition assessment has identified two types of protein-calorie malnutrition (PCM), a stress-induced hypoalbuminemic form (HAF-PCM) and a marasmic form (MF-PCM) generated by adaptation to starvation. This study evaluated the differences between these two patterns of PCM with regard to precipitating factors and the clinical sequelae of mortality, cost of total parenteral nutrition, length of hospitalization, and rate of sepsis and nosocomial infection. Of 220 patients receiving total parenteral nutrition over a 12-month period (0.7% of 30, 127 admissions), 180 were included in this study. HAF-PCM was diagnosed in 45% and MF-PCM in 25% of study patients. HAF-PCM was more common in older age groups. Women had PCM less often than did men (57% vs 83%), but whereas men developed both forms of PCM equally, women were more likely to develop HAF-PCM. Prolonged mechanical ventilation increased the likelihood of both patterns, whereas the presence of malignancy, concomitant organ failure, trauma, burns, or surgery did not increase the likelihood of developing either pattern of PCM. HAF-PCM increased the length of hospitalization by 29% and the cost of total parenteral nutrition by 42%. The presence of HAF-PCM increased four-fold the odds of dying, and the odds of developing nosocomial infection and sepsis almost 2.5 times above that seen in its absence. MF-PCM had no clinical effect of its own on any of the outcome parameters, but instead exerted only an interactive synergistic effect with HAF-PCM on length of hospitalization and cost of total parenteral nutrition.

From January 1980 to July 1990, the Hospital Infections Program of the Centers for Disease Control conducted 125 on-site epidemiologic investigations of nosocomial outbreaks. Seventy-seven (62%) were caused by bacterial pathogens, 11 (9%) were caused by fungi, 10 (8%) were caused by viruses, five (4%) were caused by mycobacteria, and 22 (18%) were caused by toxins or other organisms. The majority of fungi and mycobacterial outbreaks occurred since July 1985. Fourteen (11%) outbreaks were device related, 16 (13%) were procedure related, and 28 (22%) were product related. The proportion of outbreaks involving products, procedures, or devices increased from 47% during 1980-1985 to 67% between 1986 and July 1990. Recent outbreaks have shown that packed red blood cell transfusion-associated Yersinia enterocolitica sepsis results from contamination of the blood by the asymptomatic donor; that povidone-iodine solutions can become intrinsically contaminated and cause outbreaks of infection and/or pseudoinfection; and that rapidly growing mycobacteria can cause chronic otitis media, surgical wound infection, and hemodialysis-associated infections. These and other outbreaks demonstrate how epidemiologic and laboratory investigations can be combined to identify new pathogens and sources of infection and ultimately result in disease prevention.

From January 1981 to December 1988, we collected 11 cases of neonatal meningitis caused by Flavobacterium meningosepticum. The 6 male and 5 female newborns ranged from 3 days to 20 days old. Birth body weight varied from 1100 gm to 3600 gm. Seven cases were premature or small for date. Nosocomial infection was noted in 7 of these 11 cases. Clinically, lethargy and poor activity were the most common symptoms. Cyanosis, fever and convulsion were the next. There were 9 cases showing pleocytosis, increased protein and decreased glucose level in the cerebrospinal fluid examination. The organisms isolated in all 11 cases were susceptible to piperacillin, resistant to ampicillin, aminoglycosides and cephalosporin. Five patients were treated with antibiotics other than piperacillin for 5 to 18 days. Three patients died; hydrocephalus was the cause of death in 2 of them. Two patients were discharged against advice. Among the remaining 6 cases we gave piperacillin for 3 weeks, one case developed hydrocephalus but eventually succumbed to K. pneumoniae sepsis. Out of five surviving cases, 3 developed hydrocephalus (VP shunt performed in two). The other two patients were discharged without neurological deficit. In conclusion, neonatal Flavobacterium meningosepticum meningitis was more frequent in premature or small for date babies, and it usually appeared in nosocomial infection. The prognosis was poor and piperacillin was proved to be the drug of choice.

Nosocomial infections are among the most serious complications encountered in surgical intensive care. The most sufficient antibacterial chemotherapy of these infections is generally based on basic and empiric principles. This includes a correct decision as to the necessity for chemotherapy and the appropriate establishment of dosage, treatment duration, drug monitoring and efficacy control. Several antibiotic regimes for the treatment of the most common nosocomial infections, i.e. pneumonia, peritonitis and sepsis, are discussed.

The case records of all neonates admitted to the neonatal unit at Aga Khan University Hospital (Karachi) in a 30 month period (Nov. 86-April 89) were analysed. Of 60 neonates with confirmed sepsis, 33 (55%) had non-nosocomial infection (NNC) whereas 27 (45%) had nosocomial sepsis (NC). The most common organisms causing early-onset NNC sepsis were Klebsiella species (53%) and Escherichia coli (10%), whereas the organisms causing late-onset NNC sepsis included Salmonella parathypi (21%), Group A Streptococcus (21%), Escherichia coli (14%) and Pseudomonas species (14%). Klebsiella was the most common organism causing NC sepsis, others being Staphylococcus aureus (15%) and Serratia species (15%). The mortality in NC sepsis, early-onset and late onset NNC sepsis was 44%, 26% and 43%, respectively. Risk factors associated with NNC sepsis included low birthweight, prematurity and prolonged and complicated deliveries. There was a high incidence of drug resistance to ampicillin and gentamicin among gram-negative organisms causing sepsis (mean 67%).

Infection and sepsis are generally considered as causally related to death in intensive care unit (ICU) patients, but in several studies a decrease in infection rates was not associated with lower mortality. We therefore investigated the causes of death in surgical ICU patients, with special regard to the relationship between infection and mortality. MATERIAL AND METHODS. During the investigation period of 6 months, 502 patients were treated in the ICU (cardiac surgery: 222, thoracoabdominal surgery: 125, vascular surgery: 84, others: 14). In all patients each antibiotic therapy and infection was documented, as was the sepsis score. Definitions of infection and bacteriological monitoring were described in detail previously. In all deaths, attention was paid to an infection that was causally related to or contributed to death. In unclear cases a postmortem examination was performed. RESULTS. Forty-two patients died (8.4%). During the first 4 days 23 patients died, 11 within 24 h, because of severe trauma with severe underlying disease (main reason for death: cardiac 30%, cerebral 32%). Infections were not significant in these patients. Nineteen patients suffered from 1 or more infections (total 30). They died after a median of 16 days. The leading cause of death was multiple organ failure. In 7 of these patients a life-threatening infection was the reason for admission and, later, death. In 8 patients a nosocomial infection was causally related to or contributed to death. In the 4 other patients a postmortem examination excluded an infection as being responsible for death. DISCUSSION. More than one-half of the deaths were caused by severe trauma or severe underlying disease. Nosocomial infections could only be related to death in 1.6% of the 502 treated ICU patients. The influence of new therapeutic regimens on infection and mortality can therefore only be investigated in multicenter trials.

We report the spread of a methicillin- and gentamicin-resistant Staphylococcus aureus strain (MGRSA) from the Middle East and its subsequent dissemination within two hospitals in Dublin. The index case, a 30-year-old male with serious blast injuries was transferred from a Baghdad hospital to a Dublin hospital in May 1985. He was heavily infected with two MGRSA strains, one of which spread and was responsible for numerous episodes of nosocomial infection. This strain was very similar to MGRSA isolates recovered in a Baghdad hospital during 1984. This imported strain has now spread to two hospitals in our group causing sepsis. This report emphasizes the difficulty of detecting an imported strain in an endemic area, but above all points to the potential for spread when there is considerable movement of patients and personnel.

Sepsis is a major cause of morbidity and mortality in patients with trauma. To elucidate factors that might lead to infection, we studied the epidemiologic characteristics of nosocomial infections in our patient population with trauma. During a 3.5-year period, 2496 patients were entered into our hospital trauma registry and cross-matched with hospital infection control surveillance information. Two hundred twenty-nine patients with trauma and nosocomial infections were identified (9.2%), a figure that was nearly twice the nosocomial infection rate for the general hospital population. The majority of those infected were either orthopedic (51%), general surgical (25%), or neurosurgical (13%) patients. The most common sites of first infection were urinary tract (61%) or respiratory system (14%). Patients developing nosocomial infections were significantly older and had a higher Injury Severity Score than those who did not. Injury site was related to risk of infection with injuries of the spine, chest, and extremity showing the most significant relationship. The length of stay as well as hospital charges were significantly related to the occurrence of infectious complications. By determining the patient with trauma at risk for infection, treatment strategies can be designed to minimize septic complications.

Enterococci are important causes of community-acquired and nosocomial infection. They cause endocarditis, bacteremia, urinary tract infections and neonatal sepsis. As causes of intra-abdominal and pelvic infection, enterococci are more commonly associated with abscess, biliary tract infection, spontaneous bacterial peritonitis, post-operative infection, post-partum endomyometritis and chronic or recurrent infection. As causes of soft tissue infection, enterococci are more commonly identified in burns, decubitus or diabetic foot ulcers, and wounds associated with intestinal surgery. Enterococci are often cultured in association with other pathogens when identified in intra-abdominal, pelvic or skin and soft tissue infection. Enterococcal superinfection after therapy with cephalosporins has been well described, and occurs as a result of the low in vitro activity of cephalosporins against enterococci. The epidemiology of enterococcal infection is complex and includes both endogenous and exogenous acquisition of the organism. Antibiotic resistance is an ever-increasing problem complicating therapy in patients with enterococcal infection.

Clinicopathologic correlations for 71 cases of fatal pneumonia in children were determined. The mechanism of death for these patients was multifactorial. Severe pneumonia alone accounted for 11 deaths (15.5%). Pneumonia associated with sepsis occurred in 42 children (59.2%). Heart failure (8.5%), hypovolemia (4.2%), and nosocomial infection (12.6%) were also seen in children with fatal acute lower respiratory tract infection. Extensive consolidation, squamous metaplasia, and hyaline membranes were present in the lungs of these children. Patients with severe disease must receive, in addition to antibiotics for acute episodes, individualized intensive respiratory and supportive care. Since these types of care are not available in poor communities, vaccination against measles and vitamin A supplementation for malnourished children may ameliorate the conditions that appear to predispose these children to severe or fatal disease.
