Each year, measles kills more than 1 million children in developing countries, especially malnourished children and children with complications. Prompt hospital admission is required to prevent measles-associated deaths if children with measles exhibit a general danger sign (lethargy or unconsciousness, convulsions, inability to eat or drink, or vomiting), signs of xerophthalmia, deep or extensive mouth ulcers, severe pneumonia, severe dehydration, or severe malnutrition. No drug can treat this viral infection; measles management consists of treating complications. Health workers must insert a nasogastric tube to administer liquid foods and fluids in children with severe measles who cannot eat. They should clean both eyes with a clean cloth and water 3 times a day. They should apply tetracycline eye ointment 3 times a day for 7 days. They should give a child with signs of xerophthalmia a treatment dose of vitamin A and another dose 3 weeks later. Health workers need to clean the mouth with clean water and a pinch of salt at least 4 times a day and put 1% gentian violet on mouth sores after cleaning. They should treat an anaerobic mouth infection, indicated by a foul smelling discharge, with metronidazole. Measles patients with an acute ear infection should receive paracetamol for pain and fever and an antibiotic for the infection. In the case of ear discharge, the health worker must clean the ears at least twice a day with cotton wool or a clean cloth. They should encourage mothers of measles patients with diarrhea to continue breast feeding. Health workers must administer more fluids than usual. They need to monitor hospitalized children to detect any additional complications. They need to look for danger signs; record the child's temperature, pulse, and respiratory rate twice a day; and weigh the child daily. Children with measles must be isolated for 4 days after onset of the rash. Any child in contact with the ill child should receive a dose of measles vaccine if he/she has not already been vaccinated or had measles. A vaccine coverage rate of at least 90% is the best way to prevent measles and measles-associated deaths.

We necropsied 255 stranded green turtles Chelonia mydas with fibropapillomatosis (FP) from the Hawaiian Islands, North Pacific, from August 1993 through May 2003. Of these, 214 (84 %) were euthanized due to advanced FP and the remainder were found dead in fresh condition. Turtles were assigned a standardized tumor severity score ranging from 1 (lightly tumored) to 3 (heavily tumored). Tumors were counted and measured and categorized as external, oral, or internal and tissues evaluated by light microscopy. Turtles in tumor score 2 and 3 categories predominated, and tumor score 3 turtles were significantly larger than the other 2 categories. More juveniles stranded than subadults or adults. Total cross-sectional area of tumors increased significantly with straight carapace length (SCL). Frequency distribution of total number of external tumors per turtle was significantly skewed to the right, and there were significantly more tumors at the front than rear of turtles. Eighty percent of turtles had oral tumors, and 51% of turtles with oral tumors had tumors in the glottis. Thirty-nine percent of turtles had internal tumors, most of them in the lung, kidney and heart. Fibromas predominated in lung, kidney and musculoskeletal system whereas myxofibromas were more common in intestines and spleen. Fibrosarcomas of low-grade malignancy were most frequent in the heart, and heart tumors had a predilection for the right atrium. Turtles with FP had significant additional complications including inflammation with vascular flukes, bacterial infections, poor body condition, and necrosis of salt gland. Turtles with oral tumors were more likely to have secondary complications such as pneumonia. Most turtles came from the island of Oahu (74%) followed by Maui (20 %), Hawaii, Molokai, and Lanai (<3 % each). On Oahu, significantly more turtles we necropsied stranded along the northwestern and northeastern shores.

The present study was planned to investigate the ethnoveterinary methods practiced by the owners of pneumatic-cart pulling camels in Faisalabad Metropolis (Pakistan). During a 7-year-period (November 1992-November 1999), 200 owners of draught camels working in the city were interviewed. Information concerning the ethnoveterinary practices for the treatment of common disorders of digestive tract (indigestion, colic and diarrhea), respiratory tract (cold/rhinitis, pneumonia), skin problems (mange, ulceration of nostrils with or without nasal myiasis, ticks and lice, harness sores), systemic states (fever, ze/rba/d, anhidrosis) and preventive therapy of indigestion and halitosis was collected through interviews and collated with those documented for the treatment of desert-dwelling camels. Familiarity of owners with two traditional methods of surra (trypanosomiasis) diagnosis ('Sand-ball test' and 'Hair-stick test') known to pastorilists was also probed. In addition, the dose and frequency of use of common salt was investigated. Traditional inputs utilized by the camel owners included various plant products, insecticides, sulphur, sump oil, common salt, aspirin, naphthalene balls and milk fat. Different owners used different combinations of traditional drugs for the treatment of disorders/conditions investigated. None of the camel owners was found familiar with the 'Sand-ball test' or 'Hair-stick test' of trypanosomiasis diagnosis. For the prevention of indigestion and halitosis all camel owners had practiced administration of 'massaulas' (physic drench/balls) along with common salt (average 250 g) on weekly basis. Firing had not been used by any owner. In general, the ethnoveterinary treatment practices used by the owners of city-dwelling camels appear to be different from those documented for the treatment of diseases of desert-dwelling camels.

We studied the identity and function of the 528-bp gene immediately upstream of Legionella pneumophila F2310 ptsP (enzyme I(Ntr)). This gene, nudA, encoded for a Nudix hydrolase based on the inferred protein sequence. NudA had hydrolytic activity typical of other Nudix hydrolases, such as Escherichia coli YgdP, in that Ap(n)A's, in particular diadenosine pentaphosphate (Ap(5)A), were the preferred substrates. NudA hydrolyzed Ap(5)A to ATP plus ADP. Both ptsP and nudA were cotranscribed. Bacterial two-hybrid analysis showed no PtsP-NudA interactions. Gene nudA was present in 19 of 20 different L. pneumophila strains tested and in 5 of 10 different Legionella spp. other than L. pneumophila. An in-frame nudA mutation was made in L. pneumophila F2310 to determine the phenotype. The nudA mutant was an auxotroph that grew slowly in liquid and on solid media and had a smaller colony size than its parent. In addition, the mutant was more salt resistant than its parent and grew very poorly at 25 degrees C; all of these characteristics, as well as auxotrophy and slow-growth rate, were reversed by transcomplementation with nudA. The nudA mutant was outcompeted by about fourfold by the parent in competition studies in macrophages; transcomplementation almost completely restored this defect. Competition studies in guinea pigs with L. pneumophila pneumonia showed that the nudA mutant was outcompeted by its parent in both lung and spleen. NudA is of major importance for resisting stress in L. pneumophila and is a virulence factor.

A female patient aged 22 with fully developed symptoms of anorexia nervosa presented the following metabolic disturbances: persistent hyperuricemia, hyponatruria, (sometimes with sodium lack in urine) as well as frequent hyponatremia and hyper-uricosuria. The patient's low arterial blood pressure (70/40 mm Hg on average) was not improved by pharmacological treatment, and only high oral doses of table salt (20-70 g/24 h) did prove effective in the therapy. The subject passed seven renal calculi composed of sodium urate and uric acid. Numerous urinalyses did not reveal any changes, and bacterial cultures of the urine were also negative. After 14 years of anorexia nervosa, the patient was treated for pneumonia with gentamicin at doses of 2 x 80 mg/24 h. Following third dose of the antibiotic, the patient developed acute renal failure and was treated by haemodialysis for six weeks. The renal function came gradually to the norm. Simultaneously, all the anorexia nervosa symptoms subsided along with sodium metabolism disturbances, while purine metabolism disorders got considerably alleviated. The patient started to have her menstrual cycles again, gained 12 kg in body weight, and one year afterwards bore a son. A further 10-year follow-up period was free of any pathological changes except for a slight hyperuricemia. To the best of our knowledge, the similar case has not been reported in the medical literature and electronic data bases.

Malnutrition is a contributing cause of about half of the 10 million deaths annually worldwide, and contributes to a substantial proportion of the infectious disease morbidity among children in developing countries. Recent epidemiological and clinical evidence has shown that in most developing countries deficiencies of specific micronutrients are partly responsible for the severity of infectious disease morbidity and mortality in malnourished children. Efforts to improve micronutrient status have focused on iron, vitamin A and iodine. Supplementation with iron and vitamin A significantly reduces child mortality, while implementation of the universal salt iodization strategy reduces the incidence of iodine deficiency disorders. These strategies are considered to be among the most cost-effective health interventions in developing countries. A number of recent zinc supplementation studies in developing countries suggest that greater priority should also be given to the correction of mild to moderate zinc deficiency in children, pregnant women and lactating mothers. Some of these studies showed that zinc supplementation reduces the duration of malaria, and the severity of diarrhoea and respiratory infections (including pneumonia), and improves immunocompetence in susceptible children. The results of these studies indicate that zinc may be another specific micronutrient in which there is widespread deficiency in developing countries and that great benefits can be achieved by its supplementation.

Mechanically ventilated patients in hospitals are subjected to an increased risk of acquiring nosocomial pneumonia that sometimes has a lethal outcome. One way to minimize the risk could be to make the surfaces on endotracheal tubes antibacterial. In this study, bacterial growth was inhibited or completely prevented by silver ions wet chemically and deposited onto the tube surface. Through the wet chemical treatment developed here, a surface precipitate was formed containing silver chloride and a silver stearate salt. The identity and morphology of the surface precipitate was studied using x-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, and x-ray powder diffraction. Leaching of silver ions into solution was examined, and bacterial growth on the treated surfaces was assayed using Pseudomonas aeruginosa wild type (PAO1) bacteria. Furthermore, the minimum inhibitory concentration of silver ions was determined in liquid- and solid-rich growth medium as 23 and 18 microM, respectively, for P. aeruginosa.

A series of 4-oxo-4H-pyrido[1,2-a]pyrimidine derivatives, substituted at the 2-position with piperidines bearing quaternary ammonium salt side chains, were synthesized and evaluated for their ability to potentiate the activity of the fluoroquinolone levofloxacin (LVFX) and the beta-lactam aztreonam (AZT) in Pseudomonas aeruginosa. Attachment of the charged entity using an N-ethylcarbamoyloxy linker led to the discovery of the highly soluble compound 22 (D13-9001), which maintained good potency in vitro and displayed excellent activity in vivo in a rat pneumonia model of P. aeruginosa.

The study conducted by Seligman and coworkers included in the previous issue of Critical Care demonstrates that copeptin is a promising marker to predict outcome in patients with ventilator-associated pneumonia. In recent years, copeptin has emerged as a new prognostic marker in a variety of diseases, such as sepsis, community-acquired pneumonia, chronic obstructive pulmonary failure, heart failure and myocardial infarction. What is the pathophysiological basis for these findings? Copeptin together with vasopressin is co-secreted from the posterior pituitary and therefore mirrors the amount of vasopressin in the circulation. Vasopressin is a main secretagogue of the hypothalamo-pituitary-adrenal axis, thereby mirroring the individual stress level. Furthermore, vasopressin is an important hormone in salt and volume regulation. In this context, copeptin is also a diagnostic marker in patients with diabetes insipidus and in patients with disordered water states.

Previous studies have suggested the usefulness of postmortem serum calcium (Ca) and magnesium (Mg) for investigating cause of death. The present study investigated their levels in the pericardial fluid of serial autopsy cases of adults within 48 h postmortem (n=385), including fatalities from blunt injury (n=57), sharp instrument injury (n=9), mechanical asphyxiation (n=28), salt- and freshwater drowning (n=14 and n=61, respectively), fire fatality (n=35), intoxication (n=23), hypothermia (cold exposure, n=12), hyperthermia (heat stroke, n=7), acute cardiac death (ACD, n=86), pneumonia (n=9) and spontaneous cerebral hemorrhage (n=11). The pericardial Ca level was independent of the postmortem interval, showing a value similar to that of the clinical reference range in cases other than saltwater drowning, while the Mg level was higher than the clinical reference range and showed a mild postmortem time-dependent increase. Pericardial Ca was significantly higher for saltwater drowning than other groups, and a lower level was seen for hyperthermia, and some cases of blunt injury and intoxication. The Mg level was also significantly higher for saltwater drowning than the other groups, and showed a higher level for sharp instrument injury, but a lower level for hypothermia. The Mg/Ca ratio was higher for sharp instrument injury and saltwater drowning, but was lower for hypothermia. These findings suggest that postmortem pericardial Ca and Mg can be used to investigate the cause of death, especially for saltwater drowning, hypothermia and hyperthermia.
