Abstract: Nutritional labelling of packaged foods, mandated by law, includes details of the food content and composition - information that can affect individual and public lifestyle decisions and health status. We studied the comprehension of food labels among 120 young adults (mean age 24.1 years) attending an international travel immunization clinic. Each participant was presented with 10 food packages of common local products and was interviewed regarding the label's content. Most subjects (77.5%) reported that they took note of the food labels; women, the more educated and those engaging regularly in physical exercise were more inclined to do so. Out of a possible 10 points the overall median comprehension score was 6.0 (mean 5.7±1.8). The nutritional table section of the food label was understood the best, and the nutritional declaration section the least. The subjects thought they understood the food labels better than they actually did; 43.9% stated that they understood them very well, whereas only 27.2% achieved high scores. This inadequate comprehension of food labels represents a missed opportunity to provide essential information necessary for healthy food choices at the individual level. A combination of strategies is necessary, including improving food labels (simplification and standardization) combined with targeted educational programs.
Abstract: Abstract Breastmilk specimens from three women with acute hepatitis A virus (HAV) infection were studied. Anti-HAV immunoglobulin M and immunoglobulin G antibodies were detected in serum and breastmilk specimens of the three women. The three women also had serum HAV RNA. However, HAV RNA was detected only in two of the three breastmilk specimens. It is interesting that none of the three infants contracted clinical HAV infection. Furthermore, mothers with HAV infection should not be encouraged to discontinue breastfeeding.
Abstract: SUMMARYWe investigated a measles outbreak in the Jerusalem district in 2007-2008 (992 cases). Most cases (72·6%) were aged <15 years, 42·9% aged <5 years, and 12·8% were infants aged <1 year. The peak incidence rate was in infants aged 6-12 months (916·2/100 000). This represents a significant shift from former outbreaks in 2003-2004, where the peak incidence was in the 1-4 years age group. Of children aged <5 years the proportion aged 6-12 months tripled (7·7% vs. 25·6%). In a case-control study (74 cases, 148 controls) children who developed measles were less likely to be registered in a well-baby clinic and had lower overall immunization coverage. The differences in proportions for registration, DTaP3 and MMR1 coverage were 35·1%, 48·6% and 80·8%, respectively (all P<0·001). Rising birth order of cases and their siblings was associated with non-registration and non-compliance with MMR immunization. The vulnerability of young infants and the risk markers noted above should be taken into account in planning intervention programmes.
Abstract: Pertussis remains a cause of considerable morbidity in children worldwide. Due to the resurgence of the disease, two vaccine doses for schoolchildren were added to the routine Israeli schedule. In 2005 a 5th dose was introduced for second-graders (aged 7-8), and in 2008 an additional catch-up dose in the eighth grade (13-14 year-olds).
Abstract: Immunization coverage is a major health indicator. In Israel, routine childhood immunizations are provided at community public well-baby clinics. Immunization monitoring is an important cornerstone of a national health policy; however data obtained through sampling carries the risk of under-representation of certain population strata, particularly high risk groups. Despite high national average immunization coverage, specific subpopulations are under-immunized, as highlighted by outbreaks of vaccine-preventable diseases. The mean national immunization coverage at age 2 years (2006 data) was: DTaP-IPV-Hib4 (all 93%), HBV3 (96%), MMR1 (94%), HAV1 (90%). These reports are based on a 17% population-based sampIe in some districts and on cumulative reports in others. A national immunization registry requires data completeness, protection of confidentiality, compulsory reporting by providers, and links to other computerized health records. It should provide individual immunization data from infancy to adulthood and be accessible to both providers and consumers. In 2008 the Israel Ministry of Health launched a national immunization registry based on immunization reporting from well-baby clinics using a web-based computerized system. As of January 2010,120 well-baby clinics are connected to the nascent registry, which includes the records of some 50,000 children. The implementation of a comprehensive national immunization registry augurs well for the prospect of evidence-based assessment of the health status of children in Israel.
Abstract: Hearing screening programs in infancy should identify hearing impairment as early as possible. The two common programs utilize either objective neonatal tests (oto-acoustic emissions (OAE) or automatic auditory brainstem responses (aABR)) or behavioral screening at 7-9 months of age. Most countries employ only one of these options. The uniqueness of this study is the comparison of both hearing screening programs on the same group of children.
Abstract: We studied the age-specific population-based incidence of bacterial enteric infections caused by Shigella, Salmonella and Campylobacter, in Jerusalem. During 1990-2008, 32,408 cases were reported (incidence rate 232.1/100,000 per annum). The patterns of Shigella (47.4% of cases), Salmonella (34.4%) and Campylobacter (18.2%) infections evolved noticeably. Campylobacter rates increased from 15.0 to 110.8/100,000 per annum. Salmonella rates increased from 74.2 to 199.6/100,000 in 1995 then decreased to 39.4/100,000. Shigella showed an endemic/epidemic pattern ranging between 19.7 and 252.8/100,000. Most patients (75%) were aged <15 years; children aged <5 years comprised 56.4% of cases, despite accounting for only 12.9% of the population. Campylobacter was the predominant organism in infants aged <1 year and Shigella in the 1-4 years group. The hospitalization rates were: Shigella, 1.8%; Campylobacter, 2.3%; Salmonella, 6.9%. Infants were 2.2 times more likely to be hospitalized than children aged 1-14 years (P=0.001). Household transmission occurred in 21.2% of Shigella cases compared with 5% in the other bacteria.
Abstract: From mid-September 2009 to 7 December 2009, 173 cases of mumps have been reported in the Jerusalem District. Most cases (82.1%) were male adolescents (median age 14.5 years) who are students in religious boarding schools. The majority of them (74%) are appropriately vaccinated for their age; 67% had received two doses of mumps-containing vaccine. An epidemiologic connection has been reported with visitors from New York, some of whom had recently had mumps.
Abstract: BACKGROUND: Foodborne Salmonella enterica outbreaks constitute both a threat to public health and an economic burden worldwide. OBJECTIVES: To characterize the pathogen(s) involved and possible source of infection of an outbreak of acute gastroenteritis in a banqueting hall in Jerusalem. METHODS: We conducted interviews of guests and employees of the banqueting hall, and analyzed food items, samples from work surfaces and stool cultures. RESULTS: Of 770 persons participating in three events on 3 consecutive days at a single banqueting hall, 124 were interviewed and 75 reported symptoms. Salmonella enterica, serovar Enteritidis, phage type C-8, was isolated from 10 stool cultures (eight guests, one symptomatic employee and one asymptomatic employee) and a sample of a mayonnaise-based egg salad. Pulsed-field gel electrophoresis of the isolates revealed an identical pattern in the outbreak isolates, different from SE C-8 controls. A culture-positive asymptomatic employee was linked to all three events. After a closure order, allowing for cleaning of the banqueting hall, revision of food preparation procedures and staff instruction on hygiene, the banqueting hall was reopened with no subsequent outbreaks. CONCLUSIONS: It is often difficult to pinpoint the source of infection in S. enterica outbreaks. Using molecular subtyping methods, a link was confirmed between patients, a food handler (presumably a carrier) and a food item--all showing an identical specific Salmonella enterica serovar Enteritidis. Testing asymptomatic as well as symptomatic food handlers in outbreak investigations is imperative. Pre- and post-hiring screening might be considered as preventive measures; hygiene and sanitation education are essential.
Abstract: Neisseria meningitidis is an important cause of childhood meningitis and septicaemia. Between 1999 and 2005, 133 invasive meningococcal disease (IMD) cases occurred in Jerusalem, 112 (84.2%) of them in children aged 0-14 years. The annual incidence rate in Jerusalem was higher than the national average (2.45+/-0.6 vs. 1.13+/-0.16/100 000 population, P=0.002). Most of the children (82.1%) were from low socio-economic Arab and Jewish ultra-orthodox communities; mortality was higher among Arab than Jewish children (1.3 vs. 0.22/100 000 person-years, P=0.004). A cluster of 10 children with severe meningococcal sepsis (three fatalities) emerged in the winter of 2003-2004. Compared to the other 102 cases in 1999-2005 both meningococcaemia (100% vs. 51%, P=0.003) and mortality (30% vs. 6.9%, P=0.014) rates were higher. Serogroup B comprised 77.6% of the bacterial isolates. Pulsed-field gel electrophoresis showed considerable variability among cluster isolates, but significant resemblance in Arab cases throughout 1999-2005. The increased susceptibility of specific sub-populations to IMD necessitates further evaluation.
Abstract: Measles elimination in Europe is hindered by recurrent outbreaks, typically in non-immunised specific sub-populations. In 2003 and 2004, two measles outbreaks occurred in Jewish ultra-orthodox communities in Jerusalem, Israel. In 2007, another measles outbreak emerged in Jerusalem. Epidemiological investigation and control activities were initiated. Three measles cases (15 years old, 22 years old and an infant; all unvaccinated) were diagnosed in Jerusalem in August 2007. All three belonged to Jewish ultra-orthodox communities in London, United Kingdom, and had had contact with patients in London. The epidemiological investigation did not reveal any connection between these cases other than their place of origin. The disease spread rapidly in extremely ultra-orthodox sub-groups in Jerusalem. Until 8 January 2008, 491 cases were reported. Most patients (70%) were young children (0-14 years old), 96% unimmunized. Frequently, all the children in a large family were infected; two thirds of the cases belonged to family clusters of more than two patients per family (in part due to non-compliance with post-exposure prophylaxis recommendations). The high age-specific incidence among infants 0-1-year- (408.5/100,000) and 1-4-year-olds (264.1/100,000) is a cause for concern. The hospitalisation rate was 15% (71/491), mainly due to fever, patients (26.7%) presented with pneumonitis or pneumonia and two patients presented with encephalitis. There have not been any deaths to date. The outbreak was apparently caused by measles importation into unprotected groups. Despite a high national immunisation coverage (94-95%), programmes to increase and maintain immunisation coverage are essential, with special focus on specific sub-populations.
Abstract: BACKGROUND: Early detection, diagnosis and treatment of developmental dysplasia/dislocation of hip (DDH) are essential in preventing further disability and quality of life impairment in children. DDH risk markers and association between the age of clinical screening and outcome, were evaluated. METHODS: Clinical screening at ages birth, 6 and 13 weeks was performed in 8145 infants by pediatricians. Infants suspected for DDH were referred to the community hospital clinic for clinical evaluation by a pediatric orthopedic surgeon, imaging procedures and follow up. Demographic and perinatal characteristics of the children with suspected (n= 77) and diagnosed DDH (n= 51) were compared to matched controls (n= 154). RESULTS: The rate of suspected DDH was 0.95% and that of diagnosed DDH was 0.63%. Female gender, firstborn child and breech presentation were significantly more frequent among cases versus controls (odds ratio [OR]: 4.3, 2.7, and 6 respectively; P < 0.05). The highest positive predictive value (95.5%) in physical evaluation was any evidence of a dislocatable hip. The proportion of DDH among infants referred from the newborn department was significantly higher (OR, 4.4). DDH diagnosis after 6 weeks of age was associated with a higher likelihood of subsequent surgery and motor disability. Untoward outcome was significantly associated with increasing age of referral both at ages of 6 and 13 weeks (P < 0.05). CONCLUSIONS: Children with DDH have certain specific demographic and perinatal risk markers. Clinical screening targeted towards early diagnosis may lessen the need for surgical intervention and the risk of disability or motor handicap.
Abstract: In 2003 and 2004 two measles outbreaks occurred in Jewish ultra-orthodox communities in Jerusalem. The index case of the first outbreak (March 2003) was a 2-year-old unvaccinated child from Switzerland. Within 5 months, 107 cases (mean age 8.3+/-7.5 years) emerged in three crowded neighbourhoods. The first cases of the second outbreak (June 2004) were in three girls aged 4-5 years in one kindergarten in another community. By November 2004, 117 cases (mean age 7.3+/-6.5 years) occurred. The virus genotypes were D8 and D4 respectively. Altogether, 96 households accounted for the two outbreaks, with two or more patients per family in 79% of cases. Most cases (91.5%) were unvaccinated. Immunization coverage was lower in outbreak than in non-outbreak neighbourhoods (88.3% vs. 90.3%, P=0.001). Controlling the outbreaks necessitated a culture-sensitive approach, and targeted efforts increased MMR vaccine coverage (first dose) to 95.2%. Despite high national immunization coverage (94-95%), special attention to specific sub-populations is essential.
Abstract: A total of 161 cases of cutaneous leishmaniasis caused by Leishmania tropica occurred in the Jerusalem district during 2004-2005; 127 (79%) cases were in a town just outside Jerusalem. Environmental models suggest that in the context of global warming, this outbreak has the potential to extend into Jerusalem.
Abstract: Toxoplasma gondii (T. gondii) is the cause of toxoplasmosis. Primary infection in an immunocompetent person is usually asymptomatic. Serological surveys demonstrate that world-wide exposure to T. gondii is high (30% in US and 50-80% in Europe). Vertical transmission from a recently infected pregnant woman to her fetus may lead to congenital toxoplasmosis. The risk of such transmission increases as primary maternal infection occurs later in pregnancy. However, consequences for the fetus are more severe with transmission closer to conception. The timing of maternal primary infection is, therefore, critically linked to the clinical manifestations of the infection. Fetal infection may result in natural abortion. Often, no apparent symptoms are observed at birth and complications develop only later in life. The laboratory methods of assessing fetal risk of T. gondii infection are serology and direct tests. Screening programs for women at childbearing age or of the newborn, as well as education of the public regarding infection prevention, proved to be cost-effective and reduce the rate of infection. The impact of antiparasytic therapy on vertical transmission from mother to fetus is still controversial. However, specific therapy is recommended to be initiated as soon as infection is diagnosed.
Abstract: INTRODUCTION: Fever of unknown origin (FUO) is still a diagnostic challenge for the family physician and the internist. In the last decades a few reports have emphasized a changing pattern in the prevalence of the 3 main categories of FUO: infections, malignancies and collagen diseases. AIMS: a. to find out if the changing pattern among the main diagnoses in patients with FUO is comparable to previous reports. MATERIAL AND METHODS: Medical files of patients that were admitted in two 450 beds rural Israeli hospitals were checked by two physicians. All files of patients with either the diagnosis of FUO, or files of patients with fever that were hospitalized for a week or longer in internal medicine departments were reviewed. RESULTS: 101 files of patients fulfilling the criteria of FUO were found. Surprisingly 54.5% of them had infectious diseases, 7.9% had malignant disease and only 2% had collagen disease. CONCLUSIONS: a. Infectious diseases are still the leading cause of FUO among Israeli patients. b. The prevalence of infectious and malignant diseases is comparable to other studies, however the low rate of connective tissue diseases in our study is unusual. c. The rate of undiagnosed FUO was remarkably high (32.7%), although all these patients recovered during hospitalization and probably had self limited infectious (viral) disease.
Abstract: BACKGROUND: Nosocomial infections are a major cause of morbidity and mortality among hospitalized patients. The use of new generation antibiotics of wide spectrum caused a higher rate of virulent infections. AIMS: a) To study the prevalence, pattern and etiology of nosocomial infections in patients hospitalized in departments of internal medicine. b) to determine the characteristics of high-risk patients, deserving special precautions. METHODS: All medical files of patients who were admitted to internal medicine departments during the years 1994-8 were reviewed. All patients with nosocomial infections were included according to specific criteria. RESULTS: Of 2789 medical files, 72 (2.6%) patients, randomly elected had 76 episodes of nosocomial infection. Urinary tract infection (40.8%), pneumonia (32.9%) and sepsis (9.2%) were the most frequent infections. Mortality was significantly higher in patients with nosocomial infections--48.6% compared to 5% in a control group (p < 0.001). E. Coli, Pseudomonas auroginosa, and Staphylococcus Aureus were the most frequent infecting bacteria. Empiric antibiotic therapy was used in 84.7% of the patients. Any bacterial isolation was found in 61.9% of the patients samples (including blood cultures, urine cultures etc). Old age, female gender, prolonged hospitalization, mechanical ventilation and indwelling urinary catheter were found as risk factors for nosocomial infections. CONCLUSIONS: 1. Nosocomial infections in internal medicine departments in Brazilai hospital were found to be less common than previously reported. 2. Five risk factors for nosocomial infections were correlated with a higher prevalence of the disease. 3. Mortality due to nosocomial infections is very common, probably due to inappropriate empiric treatment and high rate of bacterial resistance. 4. Simple preventive measures as well as immediate treatment of nosocomial infection with proper antibiotics are expected to decrease mortality.
Abstract: The visual evoked potential (VEP) record in response to a pattern stimulus is a non invasive and reliable method of detecting central and peripheral nerve system abnormalities. VEP recording have been used in animals with fulminant hepatic failure, and also in-patients with hepatic encephalopathy and acute severe hepatitis. Our aims were: a. to evaluate the potency of PVEP in assessing hepatic encephalopathy. b. to find the rate of pathologic PVEP in patients with advanced liver cirrhosis. VEP was recorded in 14 chronic liver cirrhotic patients (6 alcoholic, 6 HCV-related, 2 cryptogenic) and 14 controls. Patients with any neurologic abnormalities were excluded from the study. All patients were subjected to the Mental State Score (MSS) test, and venous blood ammonia was measured on the same day of VEP recording. In 10/14 (71%) patients some VEP recording abnormality was detected. In the cirrhotic patients, P100 latency was significantly longer (P < 0.05) than in controls. Low amplitude was observed in 8 patients compared to controls. Marked increase of N75 (3 patients) and marked increase of N145 (2 patients) were observed. Mean blood ammonia and MSS score were normal in all patients. No correlation was found between both MSS score and blood ammonia levels and the P100 delay. Five out of 10 patients with pathologic VEP developed hepatic encephalpathy during a follow-up of one year, compared to one out of 4 patients with no pathology on VEP recording. VEP recording may be a valuable tool in assessing patients with early hepatic encephalopathy and in predicting encephalopathy.
Abstract: BACKGROUND: Head louse infestations are prevalent worldwide. Over the past 20-25 years, 15-20% of all children in Israel between 4 and 13 years of age have been infested with head lice. This is mainly due to the existence of ineffective pediculicides on the market. OBJECTIVE: To examine the pediculicidal efficacy and safety of a natural remedy ("Chick-Chack") and to compare it in an open clinical study with a known pesticide spray. METHODS: The natural remedy, which contains coconut oil, anise oil and ylang ylang oil, was applied to the hair of infested children three times at 5 day intervals. Each treatment lasted for 15 minutes. The control pediculicide was a spray formulation containing permethrin, malathion, piperonyl butoxide, isododecane and propellant gas, which was applied twice for 10 minutes with a 10 day interval between applications. RESULTS: Of 940 children, aged 6-14 years, from six schools in Jerusalem who were examined for head louse infestation, 199 (21.2%) were infested with lice and eggs, while 164 (17.4%) were infested only with nits. Altogether, 119 children were randomly treated with either the natural remedy or the control product. Treatment was successful with the natural remedy in 60 children (92.3%) and with the control pediculicide in 59 children (92.2%). There were no significant side effects associated with either formulation. CONCLUSIONS: The natural remedy was very effective in controlling louse infestations under clinical conditions and caused no serious side effects.
Abstract: BACKGROUND: Hepatitis B is a major problem worldwide. Israel has intermediate endemicity for hepatitis B virus, and an annual carrier rate of 1-3%. OBJECTIVE: To evaluate both the prevalence of HBV infection among family members of HBV carriers and the competence of family practitioners in performing a comprehensive assessment. METHODS: A total of 152 HB surface antigen-positive blood donors were discovered in our subdistrict during the years 1993-97. Their family physicians were questioned regarding the patients' family members. Specific information on 85 spouses and 200 children was also obtained. RESULTS: Among the 85 married carriers, 5 of the spouses (5.9%) were found to be HBsAg positive. None of the 200 children was HBsAg positive. We found that in a third (n = 52) of the patients, the sexual partner had never been tested by a primary care physician. Patients were not routinely tested for HB e antigen or anti-HBe antibodies. Neither the parents nor the siblings had undergone any serological evaluation. However, most family members of the carriers had received an HBV vaccine from their family physicians. CONCLUSIONS: Our findings show that horizontal transmission of HBV among spouses of HBV carriers still exists. We did not find any vertical transmission, probably due to male predominance and previous vaccination. Family physicians should be trained to perform an extensive serological evaluation of family members of patients with chronic HBV infection, including parents and siblings, and should vaccinate seronegative family members.
Abstract: The epidemiology and control of hepatitis A virus was investigated during an outbreak of hepatitis A in a village in Israel. Postexposure administration of immune globulin to contacts was ineffective in controlling the outbreak. However, within 2 weeks of starting a mass immunization campaign with hepatitis A vaccine, the incidence of hepatitis A declined dramatically; the last case occurred 6 weeks after the immunization program began. The study demonstrated that while postexposure administration of immune globulin may diminish but not entirely arrest transmission of hepatitis A virus, active hepatitis A vaccination is a safe and effective intervention that can be used safely in hepatitis A virus antibody-positive children.
Abstract: BACKGROUND: Universal hepatitis B vaccination in infancy was implemented in Israel in 1992. The program consists of active vaccination at birth and at 1 and 6 months of age, without hepatitis B surface antigen (HBsAg) screening during pregnancy. Infants of HBsAg carrier mothers do not receive specific hepatitis B immunoglobulin in addition to vaccine at birth. The recently arrived Jewish immigrants from Ethiopia are the group with the highest rate of HBsAg carriage (approximately 10%) in Israel. AIM: The objective of this study was to evaluate whether the present policy is effective against perinatal HBV transmission from mothers of Ethiopian origin to their infants. METHODS: The study group included 411 Israeli born children, offspring of mothers of Ethiopian origin. All infants were fully vaccinated starting at birth. Sera were collected from the children at the age of 9 to 36 months and from their mothers. Tests for HBsAg, antibodies to HBsAg (anti-HBs) and antibodies to hepatitis B core antigen (anti-HBc) were performed. RESULTS: Eighty-nine percent of the children had detectable anti-HBs, including 82.2% with protective anti-HBs concentrations (> or =10 mIU/ ml). Although 24 mothers (6.2%) were HBsAg carriers, none of the children was HBsAg-positive. Seven of 394 infants (1.7%) tested positive for anti-HBc. This test became negative in 5 of 6 who were followed for 12 months. The percentage of infants with protective anti-HBs concentrations decreased significantly from 91.4% at 9 to 12 months to 70.1% at 31 to 36 months of age. The mother's infection status was not associated with the infant's response to vaccine. Calculation based on the above data suggests that screening for HBsAg in pregnancy in that group is not cost-effective. CONCLUSIONS: Our results suggest that the Israeli vaccination program against HBV infection is effective, even in a high risk population, and additional measures are not cost-effective.
Abstract: Mutation analysis was performed on 42 unrelated Israeli Arab CF patients. The previously known mutations in this population, DF508, N1303K, G542X, 4010delTATT, and S549R(T>G), were identified in 57 CF alleles, leaving 28 CF alleles with unknown mutations. Screening of the coding sequence of the CFTR gene by a single strand conformation analysis (SSCA) and direct sequencing revealed three point mutations and two intragenic deletions, including 2183AA>G, R75X, S549R (A>C), 3120+1Kbdel8.6Kb and del(exon2). In the present sample of Israeli Arab patients, 12 mutations account for 92% of the CF alleles. The mutations DF508, N1303K, W1282X and 3120+1Kbdel8.6Kb were found in all Arab ethnic subgroups. The mutations G85E, R75X, 2183AA>G, and del(exon2) were confined to Muslim Arabs, and the mutations 4010delTATT, S549R(A>C) and G542X were confined to Christian Arabs. Hum Mutat 14:543, 1999.
Abstract: We report an unusual case of a 21-year-old man who was shot in his abdomen in the course of a robbery. He was previously diagnosed as glucose-6-phosphate dehydrogenase deficient. Mild icterus was noticed on admission to the emergency room. Exploratory laparotomy revealed a perforated ileal loop that was resected, and because the liver color was greenish black, a liver biopsy was performed during the operation. After operation the patient went through a severe icteric state that resolved spontaneously within a few days. Urinary coproporphyrin levels, along with compatible liver biopsy, confirmed the diagnosis of Dubin-Johnson disease. Severe hyperbilirubinemia after an abdominal injury is uncommon and is usually due to either a biliary duct injury or iatrogenic injury. This case presents an unusual cause of severe postoperative jaundice due to the rare coexistence of two inherited disorders.
Abstract: A 23-year-old woman was admitted with a history of 2 weeks of cough, fever and bilateral lung infiltrates. She had been diagnosed 2 months before as having ulcerative proctitis and was treated with mesalamine, which induced a full remission, but 3 antibiotic regimens failed to improve her lung disease. Since computerized tomography revealed bilateral peripheral lung infiltrates and her eosinophile count was elevated, the diagnosis of drug-induced eosinophilic pneumonia was suggested. Mesalamine and antibiotics were stopped and oral corticosteroids begun. She became almost asymptomatic a week after mesalamine withdrawal, and the x-ray became normal.
Abstract: Prevalence of hepatitis G virus (HGV) infection in the general western population ranges from 0.2-1.5%. In high-risk groups, such as patients with chronic liver disease, hematologic disorders and drug addicts, prevalence is as high as 10%-15%. Dialysis patients have increased rates of HGV infection (6%-50%). We evaluated prevalence of HGV infection among dialysis patients, and the association between HGV infection and hepatitis C virus (HCV) infection. Serum samples were screened for HGV infection by RT-PCR. Screening for HCV infection was performed by an EIA test and confirmed by RIBA and RT-PCR for HCV. Sera were also tested for HBV markers. The study group included all 78 hemodialysis patients and 7 of the 12 peritoneal dialysis patients in our unit during September to November 1997. 4 (5.2%) were HGV-positive but none were peritoneal dialysis patients. 1 of the 12 HCV-positives was also infected with HGV. HGV infection was not associated with duration of dialysis, number of blood transfusions or levels of transaminases. Prevalence of HGV infection among our hemodialysis patients was low (5.2%), but higher than reported for the general population. Prevalence of HGV/HCV infection in hemodialysis patients was low and unrelated to duration of dialysis, number of blood transfusions and levels of transaminases.
Abstract: Malaria is 1 of the main causes of death in third world countries. It has become extinct in Israel and imported cases are rare, since most visitors to endemic countries take anti-malarial prophylaxis. We report an Israeli tourist to Kenya infected with falciparum malaria complicated by severe metabolic acidosis, renal failure and adult respiratory distress syndrome. After intensive care treatment this preventable condition improved.
Abstract: The prevalence of hepatitis C virus (HCV)-RNA positivity among hemodialysis patients varies between 10 and 70%. Few previous surveys revealed high frequency of seroconversion of HCV-RNA-negative patients over the years of hemodialysis. Only few studies reported HCV genotype variability. We evaluated all 65 patients on chronic hemodialysis in our dialysis unit. All sera positive to anti-HCV on ELISA were retested by reverse transcriptase polymerase chain reaction to HCV-RNA. Sixteen patients were found anti-HCV positive on ELISA, and 8 of them were also PCR positive. Three of these eight patients seroconverted during the year 1995. Four patients had both 1a and 1b genotypes of HCV, coexistence of genotypes 1b and 4a in one patient and genotypes 1a, 1b and 2a in the remaining three patients. Mean serum aminotransferase, duration of dialysis, and number of blood units transfused were significantly higher in the HCV-PCR-positive patients compared with the HCV-PCR-negative patients. Because strict isolation methods were initiated at the end of 1995, not one new case of HCV among dialysis patients was found in 1998, although new hemodialysis patients were diagnosed as having HCV. In conclusion, genotypes 1a and 1b, as is true for the general population in Israel, were also the predominant genotypes among hemodialysis patients; the coexistence of more than one genotype is common among hemodialysis patients; seroconversion is common among these patients and strict isolation methods are efficient and should be recommended.
Abstract: We report a premature infant with Staphylococcus aureus sepsis, most probably originating from an infected peripheral iv site, and complicated by multiple brain abscesses. Diagnosis was made by cranial ultrasonography and computed tomography. Since systemic antibiotic treatment failed, surgical drainage was performed. The same organism that caused the initial sepsis grew from the pyogenic material obtained. The child is currently severely handicapped.
Abstract: Lung surfactant replacement has been tested clinically in recent years. In this study the outcome of 31 premature infants with moderate to severe neonatal respiratory distress syndrome (RDS) treated with surfactant was compared to that of 74 prematures with RDS treated conventionally by positive pressure ventilation and supportive care. The groups were well matched for gestational age, birthweight, sex, and Apgar scores at 1 and 5 min. Surfactant treatment resulted in a significant decrease in mortality--from 36.6% in the untreated group to 12.9% in the surfactant-treated group (P < 0.04). This improvement in survival was seen also in prematures with a birthweight < 1,000 g; in the untreated group mortality was 57.6% compared to 23.5% in the treated group (P < 0.05). The incidence of pneumothorax was lower in the treated group--42% vs. 13% (P < 0.01). Surfactant treatment resulted in a trend of more survivors without bronchopulmonary dysplasia or intraventricular hemorrhage, even though surfactant therapy did not change the incidence of either.
