The parents and grandparents of 100 pediatric patients hospitalized at the Hospital of the Gondar college of Medical Sciences were interviewed by means of a questionnaire containing personal data, methods of traditional medicine, treatment of 30 widespread diseases and disorders of children, views about probable causes, the diagnosis of the "local healer", and the effectiveness of his treatment. Most of those interviewed came from the Gondar region, and they had an 82% illiteracy rate. 85 of the 100 children had been treated by traditional medicine: 9 experienced improvement, but the condition of 15 worsened as a result. 68% of respondents thought that traditional medicine was more cautious and conservative, 46% cited easy access to it, and 6% the low cost as the reasons for using it. 62% vowed never to use it, though after their hospital experience, still 36% claimed they would turn to the local healer again. Over 80% had uvulectomy done to treat upper respiratory diseases, and circumcision of boys is almost 100% (it is also frequent among girls). Spirits healers are distinguished from local healers: they are Christian Orthodox clergymen who exorcise demons and ghosts. Amulets, arm rings, hair style, eye makeup is supposed to protect from the evil eye. Certain practices are dangerous: application of parts of a plant causing deep necrosis, Embelia shimperi and Hagenia abyssinia used for deforming can be deadly, phlebotomy for meningitis can cause extreme anemia, the use of red-hot iron to treat infections can not only result in scarification but also sepsis. Malnutrition and kwashiorkor is often neglected, as is tuberculosis when the local healer acts. 34 of the 100 patients had TB, 7 of whom had spondylitis. The improvement of hygiene and programs to educate the populace should be implemented.

In order to evaluate bacterial factors which might predispose to P. aeruginosa colonization or bacteremia in the granulocytopenic patient, 132 isolates recovered from 44 oncology patients were evaluated for antigenic serotype, iron correctable sensitivity to pooled human serum, antibiotic susceptibility, production of lecithinase, elastase, protease, gelatinase, pyocyanin and pyoverdin. Similarly, potential host factors, primarily total iron binding capacity, were evaluated in a subpopulation of acute leukemia patients composed of 13 control patients without P. aeruginosa cultured during their hospital course, 11 colonization only patients and 15 P. aeruginosa bacteremia patients. No significant differences were observed between strains recovered from bacteremia vs. colonization patients for extracellular enzyme activity, pigment production, serum sensitivity and antigenic serotype. Significant differences were observed between bacteremia and colonizing strains for antibiotic susceptibility to ticarcillin, 40% vs. 76% (P less than 0.002); piperacillin, 44% vs. 86% (P less than 0.006); and cefsulodin, 60% vs. 90% (P less than 0.02). Of the host factors evaluated in the acute leukemia patients, significant differences were observed between the TIBC nadir of control patients and both colonization patients (P less than 0.0002) and bacteremia patients (P less than 0.0004). P. aeruginosa bacteremia was associated with the temporal occurrence of TIBC nadir and the detection of the organism. These data suggest a possible role for beta-lactam antibiotic resistance and host iron binding capacity as determinants and possible predictors of P. aeruginosa sepsis in the granulocytopenic patient.

Trace elements like copper, zinc, iron and selenium have a significant influence on the function of the immune system. We studied plasma levels of trace elements in 53 patients with acute bacterial and viral infections. In bacterial infections (septicaemia, pneumonia, erysipelas and meningitis) the plasma concentrations of selenium, iron and zinc were decreased. Plasma copper was unchanged in patients with erysipelas, but increased in other types of bacterial infections. Although the patients with viral infections showed similar shifts of the trace elements as were observed in patients with bacterial infections, the changes were not as pronounced. A plasma selenium value below 0.8 mumol/l was found in only 6% of the patients with viral infections in contrast to 63% of the patients with septicaemia or 57% of the patients with pneumonia. Furthermore, in viral infections 60% of the zinc values were below the mean level of 12.8 mumol/l observed in healthy controls as compared with 90% of the values in patients with sepsis or 92% of the values in patients with pneumonia. The onset of change in trace elements occurred within a few days and persisted for several weeks. These changes seem to be non-specific and are independent of the agent causing infection. The different types of infections were followed by changes in most of the plasma proteins which are known to be associated with an inflammatory reaction. The changes in plasma proteins were most pronounced in patients with sepsis and pneumonia. Patients with sepsis having a high degree of inflammation did not show a positive correlation between the severity of the disease--as judged by plasma proteins--and the alterations of trace elements.

Accidental iron intoxication is one of the most serious and potentially fatal intoxications in young children. Occurrence in the adult population is rare and is usually associated with a suicide or homicide attempt. Heretofore, all reported cases have involved oral ingestion of ferrous and ferric salts of iron. In a case of fatal iron intoxication reported by Doolin and Drueck, in addition to swallowing a liquid form of ferrous chloride, the patient aspirated it and absorbed it through chemically burned and denuded areas of skin when he fell into a vat of saturated ferrous chloride at work. It is the purpose of this report to describe the first case of fatal iron intoxication in which the sole route of iron absorption was the burned skin. Clinical course of this patient paralleled that of acute oral iron intoxication with development of refractory acidosis, disseminated intravascular coagulation, respiratory and renal failure, and sepsis.

After a general discussion of the factors contributing to maternal mortality and morbidity, a solution to both of these problems is suggested for India: an initiative at the district level to improve support, supervision, training, essential midwifery and obstetric care. The general causes of the 200 or more times higher maternal morality risks in developing countries act throughout the woman's lifetime: powerlessness, illiteracy, malnutrition, deficiency of calcium, vitamin D and iron, heavy physical labor, unchecked fertility, lack of prenatal and obstetric care and illegal abortion. The most common causes of maternal morality and morbidity, eclampsia, obstructed labor, hemorrhage and sepsis, have been prevented in developed countries and in China. We know how to prevent them, by technical support and management at the district level. 4 elements are required: 1) adequate primary health care, food and universal family planning; 2) prenatal care and nutrition with referral if needed; 3) assistance of a trained person at every childbirth; 4) access to obstetric care for those at high risk. Rather than spend money or urban specialized hospital centers, half to 2/3 of all fatal complications of childbirth can be eliminated by local hospitals with the ability to do basic obstetrics such as caesareans and blood transfusions. There is a need for further health systems research in the given locale, but what we need now is an initiative on making pregnancy and childbirth safe for all women.

During a 19-month period we determined the incidence of bacterial infection among 39 patients treated with desferrioxamine who had end-stage renal disease and were undergoing maintenance hemodialysis. Twenty-three received desferrioxamine because of aluminum-related bone disease, and 16 because of iron overload. A control group of 193 patients on maintenance hemodialysis but without desferrioxamine was used. No difference was found in the incidence of septicemia or of all bacterial infections between the patients with aluminum-related bone disease treated with desferrioxamine and the control patients (0.12 vs. 0.12 septicemia per patient-therapy-year, p greater than 0.05; 0.23 vs. 0.26 bacterial infections per patient-therapy-year, p greater than 0.05). The incidence of septicemia in patients treated with desferrioxamine for iron overload, however, was almost three times that in the control patients (0.36 vs. 0.12 septicemia per patient-therapy-year, p less than 0.01). To assess the effect of iron overload itself, we determined the frequency of bacterial infection in patients on regular hemodialysis who have never received desferrioxamine. These were subdivided into three groups according to serum ferritin level which indicated normal or low iron stores (Group I: serum ferritin 10-330 micrograms/l, n = 125), moderate (Group II: serum ferritin 331-1000 micrograms/l, n = 49) or more advanced iron overload (Group III: serum ferritin 1001-2000 micrograms/l, n = 10). Compared to patients with normal or low serum ferritin levels (Group I), we found a significantly higher rate of bacterial infection among patients in Group II compared with Group I (0.18 vs. 0.34 infections per patient-therapy-year, p less than 0.05) and Group III compared with Group I (0.18 vs. 0.58 infections per patient-therapy-year, p less than 0.01). These results suggest that treatment with desferrioxamine does not favour the development of septicemia or bacterial infection independently of iron overload and that iron overload itself may predispose patients on regular hemodialysis to bacterial infection.

A total of 516 strains of Escherichia coli were screened for the presence and expression of the aerobactin iron uptake system. The incidence was markedly higher among clinical isolates from patients with septicemia (68.8%), pyelonephritis (74.6%), and symptomatic (59.8%) and asymptomatic (63.2%) lower urinary tract infections than among normal human fecal isolates (34.3%).

The effect of inoculation with Escherichia coli on serum iron concentrations of turkeys and the effect of exogenous iron, as ferric ammonium citrate, on E coli septicemia in turkeys were determined. Inoculation of air sacs with E coli produced hypoferremia in 18-day-old turkeys. Administration of iron with E coli significantly (P less than 0.01) increased mortality, frequency and degree of bacteremia, and severity of lesions in inoculated turkeys, compared with those in turkeys given E coli but not given iron. Similar results were seen whether iron was inoculated at the same location as E coli or at a different location.

Production of cytotoxin and enterotoxin by Aeromonas strains obtained from stools of 50 children in Mexico and Texas and from blood of 9 children with sepsis was determined. Results were correlated with clinical features of infected children as well as with biochemical traits of Aeromonas strains. Cytotoxin was produced by 40 of 42 Aeromonas strains (95%) isolated from stools of children with diarrhea, by all 8 isolates from stools of well children, and by all 9 isolates from children with sepsis. There was no difference in the quantities (amount of cytotoxin per milligram of protein required to kill 50% of the cells) of cytotoxin produced and in clinical manifestations among the groups. None of the isolates produced a toxin that could be neutralized by antiserum raised against Shiga toxin produced by Shigella dysenteriae 1 60R. Heat-labile-like enterotoxin (LT) was produced by 26 of 42 stool isolates (62%), while only 1 of the 42 isolates (2%) produced enterotoxinlike activity in suckling mice; 65% of the cytotoxin-producing strains also produced an LT-like material. All strains from blood produced LT-like material, and 2 of 6 (33%) produced activity in suckling mice. All strains produced hemolysin; 37 of 57 (65%) were Voges-Proskauer positive; 27 of 57 (47%) were lysine decarboxylase positive by API 20E strips, none were positive for lysine decarboxylose production by lysin-iron agar slants at 24 h, but 17 of 54 (31%) were positive at 48 h. There was no correlation between biochemical reactions and enterotoxin or cytotoxin production. There appears to be no correlation between toxin production by Aeromonas spp. and gastroenteritis.

Vibrio vulnificus was isolated from United States West Coast estuaries at a low frequency (5.9%) from 529 samples of water, shellfish, and sediment. Four strains tested with iron-treated mice had 50% lethal dose values ranging from 7.6 to 360 CFU, compared with a 50% lethal dose of 4.9 CFU for a clinical isolate that caused the death of a septicemic patient. The presence of this pathogen may be a hazard to users of marine beaches and consumers of raw shellfish on the West Coast, especially to persons most susceptible to V. vulnificus septicemia. Species-specific antiflagellar serum and a gene probe for cytotoxin-hemolysin production were useful for screening these environmental isolates.
