Enterobiasis among Pre-School Children in Gaza Strip, Palestine.
No full textBackground: Enterobius is one of the common nematode causing health problem in developing countries. The aim of the present study was to estimates the prevalence of Enterobius vermicularis in Gaza Strip.
Methods: This is a cross-sectional study which included 149 pre-school children who are residing in four Governorates in Gaza Strip; north Gaza, Gaza, mid zone and Khanyounis in Gaza Strip. Scotch tape preparation (STP) was used for the detection of E.vermicularis eggs.
Results: Children with employee father had high prevalence of E. vermicularis with a percentage of (47.3%) while those with un-employee father had a percentage of (45.7%) but there was no significant difference. The same results were found with working mother. Families with low family income had children with low rate of E. vermicularis (40.5%) but families with high family income had children with high rate of E. vermicularis (52.8%). Children who are drinking water from filters had high rate of E. vermicularis than others who are drinking from other sources (65%) with a significant difference (p=0.003).
Conclusion: The study concluded that enterobiasis constituted a high prevalence among pre-school children in Gaza strip (46.3%). These results may shed the light on an infectious disease in Gaza Strip and help health authorities to take serious measures for prevention and control, and educate peoples towards the biology of Enterobius. It is recommended that STP should be used to confirm the clinical diagnosis of physicians in case of anal itching
Breast Feeding, Complementary Feeding, and Weaning Practices, among Children up to 2 Years Old in Gaza Strip.
No full textObjective: The experience of the authors working with mothers in Gaza community in the of child and infant nutrition and their observation of incorrect weaning behavior, necessitated assessment of weaning practices for future intervention. The objectives of this study is to describe infant feeding attitudes and practices during breast feeding( BF), complementary feeding (CF) and weaning (WP) for a sample of nursing mothers in the Gaza strip (GS) during the year 2009.
Methods: The study is of cross -sectional design. The study sample consisted of 269 mothers of infants aged less than two years old. Data were collected through face to face interviews of the mothers. The questionnaire contained questions related to infant feeding and weaning attitudes and practices of mothers to wards their infants. Chi-square test was used to analyze data and P value less than 0.05 was considered significant. Ethical approval was obtained verbally from each participant.
Results: In the present study 55.8% of infants were boys and 44.2% girls (Minimum age 1 month and maximum age 24 month). The study revealed that 48.8% of the mothers weaned their children either suddenly or gradually. Complementary feeding was added between 3-5 months to 54.9% of the children that started to receive complementary feeding (post breast feeding). The key limitation of this study was that the research team collected limited samples from all the veregions of Gaza Strip due to limited human and non -human resources.
Conclusion: Satiety from complementary feeding was the prime cause fo rweaning followed by pregnancy of the nursing mother and then by breast refusal by the baby. The study showed lack of adequate knowledge by nursing mothers to wards the procedure, practice and time of weaning and the importance of breast feeding. We recommend use of health education to assess and support the proper feeding practices amongst nursing mothers
Prevalence of intestinal parasites among school children in Gaza City, Gaza Strip
Full text linkA total of 489 stool specimens were collected from school children aged 6-11 years. The target area is overcrowded, with improper sewage disposal system and low socioeconomic standards. A questionnaire was designed to include relevant informations. Each stool specimen was processed by the direct smear microscopy, zinc sulphate flotation technique and formol-ether sedimentation technique. The present study revealed an overall prevalence at 27.6%. Six parasites were detected. Giardia lamblia ( 62.2% was the most frequent species found, followed by Ascaris lumbricoides ( 20.1% then, Entamoeba histolytica ( 13.3% . The prevalence of these parasites was found to be related to age, socioeconomic and sanitation conditions. Most of the other parasitic infections were of mild intensity. There is an urgent need to correct the present situation by improving the living conditions, providing facilities for the population such as modern housing, proper sewage disposal system, health education and execution of survey programs for parasites to treat the infected persons
Gastrointetinal parasites and Ectoparasites Biodiversity of Rattus Rattus Trapped friom Khan younis and Jabalia in, Gaza Strip, Palestine.
No full textThis study identified the zoonotic endo-parasites and ecto-parasites and their prevalence found in Rattus rattus. A total of 41 rats of house (black) rat and Norway (brown) rat were trapped from two regions of Gaza strip. After dissection, isolated protozoa, nematodes and cestodes were identified respectively according standard keys. The results showed that prevalence of intestinal parasites among rats was 24/41 (58.5%) and males were infected more than females. A high prevalence of protozoa was in autumn compared to other seasons. The intestinal parasites were encountered: G. lamblia 6 (14.6%); E. histolytica/dispar 7 (17.1%); Iso-spora 4 (9.8%); Canthocephala1 (2.4%); Syphacia obvelata 6 (20%); Heligmonoides josephi 3(10%); Strongyloides egg 1 (2.4%); Hymenolepis diminuta 15 (36.6%). The insects were Xenopsylla cheopis 7 (17.1%); Polyplax spinulosa 3 (7.3%)
Seroprevalence of Toxoplasma gondii, Cytomegalovirus, Rubella virus and Chlamydia trachomatis among infertile women attending in vitro fertilizaton center, Gaza strip, Palestine.
No full textIn the present study, the esroprevalence of Toxoplasma gondii, rubella, cytomegalovirus (CMV) and chlamydia trachomatis in Palestine women was determined through antenatal screening. The study included 1954 Palestinian women records which reviewed and analyzied statistically from 2000-2005. Those women attended in vito fertilization center in gaza complaining from infertility and abortion. Anti-Toxoplasma, anti-rubella, anti-CMV and anti-Chlamydia IgM antibodies were assayed using an enzyme linked immunosorbant assay (ELISA). positive results were found in 7.9%, 6%, 7% and 12.8% for T. gondii, CMV, Rubella and C. trachomatis antibodies. A high significant infection rate was observed in year 2003 (p = 0.001) fot T. gondii. A clear variation with statistical significant was observed in the seroprevalence for all the studied pathogens regarding year of collection and age of women. The study indicated that T. gondii, Rubella, (CMV) and C. trachomatis are still constitute a puplic health problem among pregnant women and considered one of the abortion factors
Evaluating the Effect of Selected Medicinal Plant Extracts and their Synergistic Effect with Metronidazole against Entamoeba histolytica
No full textIntroduction: Intestinal infection with Entamoeba histolytica is an important cause of diarrhoea world-wide especially where sanitation conditions are poor. Medicinal plants have played a significant role in various traditional systems of medications including intestinal infections caused by E. histolytica. Objectives: To investigate the antiamoebic activity of pomegranate, castor and thyme aqueous and alcoholic extracts, in addition to thyme oil and pomergnate juice against E. histolytica and to determine the synergistic effect of these plant extracts with the antibiotic metronidazole. Methods: Three medicinal plants pomegranate ( Punica granatum , castor ( Ricinus communis L and thyme ( Thymus vulgaris L were used in this study. Some of these plants were bought from fruit's market in Gaza and some were collected from some regions in Gaza; each plant was dried then extracted according to standard extraction method using Soxhlet apparatus. E. histolytica was cultured in a modified diphasic liver infusion agar medium in vitro conditions to study the effect of these plant extracts on E. histolytica and their synergestic effect with the antibiotic metronidazole. The type of E. histolytica was confirmed using PCR. Results: Successful cultures of E. histolytica were obtained. All the plant materials used in this study possessed antiamoebic activity in vitro with different levels except the aqueous extract of R. communis leaves which also was the only one didn’t show synergistic effect with metronidazole at tested concentrations. Alcoholic extract of P. granatum pulp had the strongest antiamoebic activity with MIC of < 5 mg/ml while the aqueous extract of T. vulgaris leaves had the weakest antiamoebic activity with a MIC of < 20 mg/ml. Oils and Juice: P. granatum juice possessed antiamoebic activity and synergistic effect with a MIC < 12.5 % ( v/v . T. vulgaris oil not only possessed antiamoebic activity and synergistic effect but also had the strongest activity and a MIC of < 6.5% ( v/v , and the best synergistic effect. Metronidazole is still effective against E. histolytica with a MIC < 20 µg/ml and exhibit greater amoebicidal activity as compared with the plant extracts. It is recommended that pomegranate and thyme should be advised by physicians to treat E. histolytica infection with or without
metronidazole. The plant extracts which showed a good amoebicidal activity in vitro should be tested in vivo on experimental animals to evaluate their amoebicidal effect and their synergistic effect with metronidazole on E. histolytica and also recommended to raise awareness regarding the use of medicinal plants to treat parasitic infections
