The prevalence of delta virus infection in chronic liver disease in Egyptian children in comparison with some other countries

BACKGROUND: Hepatitis Delta Virus (HDV) infection has a worldwide distribution. The aim of this study was to establish its prevalence in Egyptian children with chronic liver disease, and its role in the development and progress of hepatic illness. METHODS: A prospective study of 45 Egyptian children who had liver cirrhosis (n = 24) or chronic hepatitis (n = 21) was done. They were consecutively chosen. Their ages ranged from 2-15 years (median = 5). Serological studies were performed to detect the presence of hepatitis B surface antigen (HBs Ag) and HDV infection IgG antibody (IgG anti-HD). RESULTS: Anti-delta antibody (IgG anti-HD) was detected in only four children with hepatic cirrhosis and non of the chronic hepatitis, with an overall prevalence of 8.9% (4/45). Three of them (75%) were hepatitis B surface antigen (HBs Ag) negative. Significant statistical association between delta infection and the state of hepatic illness was detected (p < 0.05). Whereas HBs Ag was detected in 54% (13/24) of liver cirrhosis and 52% (11/21) of chronic hepatitis, with an overall prevalence of 53% (24/45). There was no statistically significant association between HBs Ag positivity and state of hepatic illness. CONCLUSIONS: The prevalence of HDV infection is 8.9% of Egyptian children with chronic liver disease. HDV infection in children is associated with advanced chronic liver disease.

Poliomyelitis trends in Pondicherry, south India, 1989-91.

STUDY OBJECTIVES: To assess the poliomyelitis trend, including study of the epidemiological features, and to correlate this with the immunisation coverage of infants. DESIGN: Three annual lameness surveys in children aged 0-60 months employing cluster sampling methods and a series of five cross sectional surveys of immunisation coverage in children aged 12-23 months of age were undertaken. SETTING: Pondicherry, India, 1988-92. SUBJECTS: More than 10,000 children in the age group of 0-60 months took part in the three annual lameness surveys and samples of 210 children aged 12-23 months were covered each year in immunisation coverage surveys. MEASUREMENTS AND MAIN RESULTS: Altogether 50 of 11,461, 24 of 10,093, and 17 of 11,218 children surveyed during 1989, 1990, and 1991 respectively had become lame as a result of poliomyelitis, giving prevalences of 4.4, 2.4, and 1.5 per 1000 children for the three surveys. The corrected prevalences of poliomyelitis were 5.9, 3.2, and 2.0 per 1000 children during 1989, 1990, and 1991 respectively. The proportion of cases aged up to 36 months fell from 48% in 1989 to 12.5% in 1990 and 6% in 1991. The age at onset was less than 1 year in most. The median age at onset was 10.7 months. About 54% of the affected children had received three doses of oral poliomyelitis vaccine (OPV) before the onset of paralysis. In 1988 immunisation coverage for the third dose of OPV was 91% and in 1992 it was 97.6%. The drop out rate for the first versus the third dose of OPV fell from 6.3 in 1988 to 1.9% in 1992. CONCLUSION: Three successive annual lameness surveys showed that poliomyelitis was declining between 1989 and 1991. Five immunisation coverage surveys conducted from 1988 to 1992 showed high initial coverage followed by an improvement in the form of almost universal coverage for OPV.     

Comparison between handgrip strength, subjective global assessment, and prognostic nutritional index in assessing malnutrition and predicting clinical outcome in cirrhotic outpatients

OBJECTIVE: This study compared three methods of assessing malnutrition in cirrhotics and correlated nutritional status with clinical outcome. METHODS: This cross-sectional study evaluated nutritional status by subjective global assessment (SGA), prognostic nutritional index (PNI), and handgrip strength (HG) in outpatients with cirrhosis (n = 50) and two control groups with hypertension (n = 46) and functional gastrointestinal disorders (n = 49). Patients with cirrhosis were followed for 1 y to verify the incidence of major complications, the need for transplantation, and death. RESULTS: Among patients with cirrhosis, 88% were Child-Pugh A and only 12% were Child-Pugh B. Among these, prevalences of malnutrition were 28% by SGA, 18.7% by PNI, and 63% by HG (P < 0.05). HG, but not SGA or PNI, predicted a poorer clinical outcome in patients with cirrhosis because major complications such as uncontrolled ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, and hepatorenal syndrome developed in 65.5% of malnourished patients versus 11.8% of well-nourished ones (P < 0.05). No significant differences by any method were seen between the two groups regarding liver transplantation or death. CONCLUSIONS: There was a high prevalence of malnutrition in cirrhotic outpatients, especially when assessed by HG, which was superior to SGA and PNI in this study. HG was the only technique that predicted a significant incidence of major complications in 1 y in undernourished cirrhotic patients.     

The role of oxidative stress and arterial blood supply in the transplanted liver function

INTRODUCTION: Reperfusion injury and hepatic artery thrombosis are major causes of graft failure after liver transplantation. The magnitude of oxidative stress increases after reperfusion and the appearance of an arterial thrombosis presents a higher risk for the graft and patient survival. AIM OF THE STUDY: The aim of the study was to detect the level of oxidative stress in the perioperative period of transplantation. METHODS: Clinical documentations of 32 patients were investigated and the level of myeloperoxidase (MPO) was measured for the monitoring of the oxidative stress. RESULTS: The mean age of the patients was 43 years and hepatitis C cirrhosis was the most common indication (14 cases, 43%). Two retransplantations were done. In 24 cases (75%) the primary graft functions and patient survival were good. Eight patients died, in two cases because of acute liver failure, in two cases due to primary non function and in four cases due to late complications. The incidence of hepatic artery thrombosis was 11% (4 cases) and the incidence of acute rejection was 35% (12 cases). The level of MPO was higher (65 ng/ml) in all patients before operation. After the first 48 hours this level increased significantly (p < 0.0001) up to the mean level of 123 ng/ml and decreased after one week. In the cases with acute liver failure and hepatic artery thrombosis high levels of MPO were measured. CONCLUSION: This study provides evidence of increased oxidative stress before liver transplantation. The magnitude of these changes increased after operation, mostly in cases with acute liver failure and hepatic artery thrombosis. Reducing the reperfusion injury and performing an "ideal" arterial supply for the liver-graft present better survival.     

Liver transplantation

Liver transplantation is an efficient therapeutic option for terminal hepatic diseases. The principal indications of liver transplantation are hepatic cirrhosis, hepatic tumours (mainly, hepatocellular carcinoma) and acute liver failure. Over the years, the absolute contraindications for a transplant have lessened. Surgical techniques have also undergone changes. The results of liver transplant have improved so that survival one year after the transplant is close to 90% and after five years some 80% of transplanted patients continue to live.

Rash after measles vaccination: laboratory analysis of cases reported in São Paulo,Brazil

OBJECTIVE: The clinical differential diagnosis of rash due to viral infections is often difficult, and misdiagnosis is not rare, especially after the introduction of measles and rubella vaccination. A study to determine the etiological diagnosis of exanthema was carried out in a group of children after measles vaccination. METHODS: Sera collected from children with rash who received measles vaccine were reported in 1999. They were analyzed for IgM antibodies against measles virus, rubella virus, human parvovirus B19 (HPV B19) using ELISA commercial techniques, and human herpes virus 6 (HHV 6) using immunofluorescence commercial technique. Viremia for each of those viruses was tested using a polimerase chain reaction (PCR). RESULTS: A total of 17 cases of children with exanthema after measles immunization were reported in 1999. The children, aged 9 to 12 months (median 10 months), had a blood sample taken for laboratory analysis. The time between vaccination and the first rash signs varied from 1 to 60 days. The serological results of those 17 children suspected of measles or rubella infection showed the following etiological diagnosis: 17.6% (3 in 17) HPV B19 infection; 76.5% (13 in 17) HHV 6 infection; 5.9% (1 in 17) rash due to measles vaccine. CONCLUSIONS: The study data indicate that infection due to HPV B19 or HHV 6 can be misdiagnosed as exanthema due to measles vaccination. Therefore, it is important to better characterize the etiology of rash in order to avoid attributing it incorrectly to measles vaccine.     

Epidemiological changes of paediatric urolithiasis in Tunisia

Background: The clinical and biological characteristics of urolithiasis in children are still evolving in our country. Since the eighties no study has been conducted to determine incidence of urolithiasis in Tunisia. Aim: To define the current status of urolithiasis inTunisian children. Methods: The records of 414 children with urolithiasis treated between 1983 and 2007 were found in a multi-centric study which took into consideration to age, sex, and history diagnosis and physical, laboratory, and radiologic findings. Clinical and biological date were performed in 344 cases. Stone analysis was performed by spectrophotometry. Results: The incidence of paediatric urolithiasis has steadly decreased from 0.7/ 10 000 of the child population / year in 1991-1994 to 0.1 cases/10 000 children/ year in 2007. There was a continuous decrease in bladder stone over the past 25 years (47.1% in 1982-1986 Vs 10.2% in 2002-2007). Stones were homogeneous in 31.4% of cases. The main component was calcium oxalate stones in 36.4% of the cases. Since the eighties the increase of oxalates stones (15.6% in eighties Vs 51.5% actually) were with depends to purines and struvite stones. Conclusion: Epidemiologic characteristics of the urinary lithiasis (sex, age, localization and composition) have changed in Tunisia, due to the the improvements of standard of living. The occidentalization of the nutritional practices and the receding of the culinary traditions gave birth to new risks of urolithiasis characterized by the emergence of calcium oxalate stones.     

Oral cholera vaccination coverage after the first global stockpile deployment in Haiti, 2014

IntroductionIn 2014, an oral cholera vaccine (OCV) campaign targeting 185,314 persons aged ≥1 years was conducted in 3 departments via fixed post and door-to-door strategies. This was the first use of the global OCV stockpile in Haiti.MethodsWe conducted a multi-stage cluster survey to assess departmental OCV coverage. Target population estimates were projected from the 2003 Haiti population census with adjustments for population growth and estimated proportion of pregnant women. In the three departments, we sampled 30/106 enumeration areas (EAs) in Artibonite, 30/244 EAs in Centre, and 20/29 EAs in Ouest; 20 households were systematically sampled in each EA. Household and individual interviews using a standard questionnaire were conducted in each selected household; data on OCV receipt were obtained from vaccination card or verbal report. We calculated OCV campaign coverage estimates and 95% confidence intervals (CIs) accounting for survey design.ResultsOverall two-dose OCV coverage was 70% (95% CI: 60, 79), 63% (95% CI: 55, 71), and 44% (95% CI: 35, 53) in Artibonite, Centre, and Ouest, respectively. Two-dose coverage was higher in the 1–4 years age group than among those ≥ 15 years in Artibonite (difference: 11%; 95% CI: 5%, 17%) and Ouest (difference: 12%; 95% CI: 3, 20). A higher percentage of children aged 5–14 years received both recommended doses than did those ≥ 15 years (Artibonite: 14% (95% CI: 8%, 19%) difference; Centre: 11% difference (95% CI: 5%, 17%); Ouest: 10% difference (95% CI: 2%, 17%). The most common reason for not receiving any OCV dose was being absent during the campaign or not having heard about vaccination activities.ConclusionsWhile coverage estimates in Artibonite and Centre were comparable with other OCV campaigns in Haiti and elsewhere, inadequate social mobilization and outdated population estimates might have contributed to lower coverage in Ouest.     

Indications and outcomes of surgical treatment of gastro-duodenal ulcer in child and adolescent. About 45 cases

The goal of this study was to determine the indications and assess the results of surgery in the treatment of gastro-duodenal ulcers in children and adolescents. This is a retrospective study of 45 patients operated for duodenal ulcer in Sahloul Teaching Hospital (Susa, Tunisia) over period of 14 years (1988 - 2001). The study is about 41 boys and 4 girls aged between 8 and 18 years (mean age: 15 1/2 years). Surgery was undertaker in cases of bleeding ulcer (9 cases), perforation (26 cases), stenosis (7 cases), resistance to medical treatment (3 cases). The after-effects were mild in 40 cases with an average hospital stay of 6 days. Later after-effects comprised ulcerous relapse (2 cases), stricture of the pyloroplasty (2 cases), an diarrhea follwing vagotomy combined with pyloroplasty in one case. Indications of surgical treatment of gastro-duodenal ulcers in children and adolescents are, nowadays, nearly limited to complicated forms of the illness. Outcomes of surgical treatment are globally satisfactory.     

Incidence and management of male urethritis in the district of Tunis

BACKGROUND: The aim of the study was to evaluate the incidence of male urethritis and the relative frequency of the different etiological agents in order to adapt standard case management. METHODS: The incidence of urethritis has been estimated with a postal study made on a sample of druggists (1/10) of the area. The total observation period was four weeks. The relative frequency of the etiological agents and the positive predictive value (PPV) of the therapeutic approach based on antibiotic treatment of gonorrhoea and Chlamydia trachomatis was achieved on 92 cases of male urethritis attending general physicians in two polyclinics. RESULTS: The annual incidence of male urethritis was estimated at 680 per 100,000. The relative frequency of etiological agents was as 34.7% for Neisseria gonorrhoea, 7.6% for Chlamydia trachomatis and was found at 3.3% for Trichomonas vaginalis; the PPV was only 43% because of the high proportion of negative results reported by the laboratory. CONCLUSION: Gonococcal urethritis incidence tends to decrease regarding non gonococcal urethritis and the therapeutic approach appears to be warranted.     

Rural,urban, and suburban differences in influenza vaccination coverage among children

Influenza vaccination is the primary way to prevent influenza, yet influenza vaccination coverage remains low in the United States. Previous studies have shown that children residing in rural areas have less access to healthcare and lower vaccination coverage for some vaccines. Influenza vaccination coverage among children 6 months–17 years by rural/urban residence during the 2011–12 through 2018–19 influenza seasons was examined using National Immunization Survey-Flu data. The Council of American Survey Research Organizations response rates for National Immunization Survey-Flu ranged from 48% to 65% (2011–12 through the 2017–18 seasons) for the landline sample and 20%–39% (2011–12 through the 2018–19 seasons) for the cellular telephone sample. Children residing in rural areas had influenza vaccination coverage that ranged from 7.9 (2012–13 season) to 12.6 (2016–17 season) percentage points lower than children residing in urban areas, and ranged from 4.5 (2012–13 season) to 7.4 (2016–17 season) percentage points lower than children residing in suburban areas. The differences in influenza vaccination coverage among rural, suburban, and urban children were consistent over the eight seasons studied. Lower influenza vaccination coverage was observed among rural children regardless of child’s age, mother’s education, household income, or number of children under 18 years of age in the household. Rural versus urban and suburban differences in influenza vaccination coverage remained statistically significant while adjusting for selected sociodemographic characteristics. A better understanding of the reasons for lower childhood influenza vaccination coverage for children in rural and suburban areas is needed.     

Complications hépatiques de la nutrition artificielle chez l'enfant : stratégies thérapeutiques

Parenteral nutrition-associated complications in children can result in the deterioration of hepatic structure and function which ultimately leads to cirrhosis. The frequency and prevalence of these complications are difficult to clarify; moreover, their presentation is polymorphous (lithiasis, steatosis, cholestasis, fibrosis) and nonspecific. Patients at risk need to be clearly identified, since preventive intervention and treatment can slow down the disease's progression. However, when intestinal functions become severely impaired with absolute dependency on parenteral nutrition, intestinal transplantation becomes the sole treatment.     

Measles outbreak in the Republic of the Marshall Islands, 2003

BACKGROUND: Measles is a highly contagious viral infection. Measles transmission can be prevented through high population immunity (>or=95%) achieved by measles vaccination. In the Republic of the Marshall Islands (RMI), no measles cases were reported during 1989-2002; however, a large measles outbreak occurred in 2003. Reported 1-dose measles vaccine coverage among children aged 12-23 months varied widely (52-94%) between 1990 and 2000. METHODS: RMI is a Pacific island nation (1999 population: 50,840). A measles case was defined as fever, rash, and cough, or coryza, or conjunctivitis, in an RMI resident between July 13 and November 7, 2003. A vaccination campaign was used for outbreak control. RESULTS: Of the 826 reported measles cases, 766 (92%) occurred in the capital (Majuro). There were 186 (23%) cases in infants aged <1 year and 309 (37%) of cases in persons aged >or=15 years. The attack rate was highest among infants (Majuro atoll: 213 cases/1,000 infants). Among cases aged 1-14 years, 281 (59%) reported no measles vaccination before July 2003. There were 100 hospitalizations and 3 deaths. The measles H1 genotype was identified. The vaccination campaign resulted in 93% coverage among persons aged 6 months to 40 years. Interpretation Populations without endemic measles transmission can accumulate substantial susceptibility and be at risk for large outbreaks when measles virus is imported. 'Islands' of measles susceptibility may develop in infants, adults, and any groups with low vaccine coverage. To prevent outbreaks, high population immunity must be sustained by maintaining and documenting high vaccine coverage.
