Risk factors and effects of infestation with Pediculosis Capitis and Scabies among primary school students in Cairo, Egypt

Background: Pediculosis capitis [PC] and scabies are an important public health problem in childhood. They have a worldwide distribution. Also, they have many effects on the infested students

Objectives: To define the prevalence of PC and scabies, to find out the socio-demographic, environment, and health care behavior risk factors, and to determine the effects on the studied students in Cairo, Egypt

Subjects and Methods: A cross-section, analytical study design was chosen to conduct this work. Three primary schools were the field of this study. Total number of the students was 1987. The students were clinically examined; for each infested case with PC and/ or scabies a control student was chosen

Results: Prevalence of PC and scabies was 10.2% and 3.4%, respectively. These infestations were more common significantly among students in the public school. Significant social risk factors of infested students were the low level of head of the family education, occupation, and social status. Also, significant personal hygiene risk factors were poor hair, body, and environment hygiene. While significant health care behavior risk factors were student never received skin examination, no early consultation for skin diseases, and no compliance with therapy. Also; female gender, the last birth order child, had previous infestation with PC, had sibling[s] with PC, and had parents with history of infestation with PC were significant risk factors. On the other hand; male gender, the last birth order child, had previous infestation with scabies, had sibling[s] with scabies, and had parents with history of infestation with scabies were significant risk factors. Further, the PC cases with crowding index >1, had no sun access, had shared water supply and bathing facilities, co-sleeping, had no short cut hair, and sharing hair brushes were significant risk factors. On the other hand, the scabitcs with crowding index >1, had no sun access, had shared water supply and bathing facilities, and co-sleeping were significant risk factors. Lastly, presences of psychiatric, sleep, and peers' relations disturbances were significantly more common among the infested students

Conclusions: Many risk factors of PC and scabies can be manipulated, so these infestations can be prevented, so many health hazards on the students could be prevented

Recommendations: Improving students' hygiene, health education, and regular dermatological screening and treatment of students are important essentiality. Also, dermatological health component should be integrated in school health program. Lastly, further studies in different rural and urban areas in Egypt are recommended

Psoriasis and psoriatic arthritis: characteristics and risk factors among adult patients in Egypt

Psoriasis and psoriatic arthritis are common, chronic, immune mediated disease of the skin and joints. Interaction between genes and environment are important in disease causation. The aim of the present study was to determine the socioemographic and clinical characters of adult patients with psoriasis and those with psoriatic arthritis, to define psoriasis and psoriatic arthritis etiological risk factors, and to define the relationship between psoriasis severity and these items. This study was conducted at Dermatology Clinic, Al-Hussein University Hospital. A case-control study design was chosen to perform this research. The study was conducted on 100 adult patients with psoriasis and an equal number of free adults as controls. Criteria for diagnosis of psoriasis and psoriatic arthritis were used. A comprehensive questionnaire was used to survey the studied groups. Body surface area of the affected patients was used as a marker of disease severity. The study showed that 44.0% of the cases had psoriasis age of onset; 22-45 years. Stress was the most common etiological risk factor, 67.0%. While, the most important risk factors were family history of psoriasis, recurrent pharyngitis, smoking >/=20 cigarettes/ day and higher level of education, odds ratio [OR]=7.58, 5.94, 2.78 and 2.69, respectively. Also, 32.0% of the patients had psoriatic arthritis. Psoriatic arthritis comes after psoriasis and had mild severity in 65.6% and 68.7% of the cases, respectively. The most important etiological risk factors were severe psoriasis, smoking >/= 20 cigarettes/day and early onset of psoriasis, OR=9.64, 3.06 and 2.72, respectively. The epidemiology of psoriasis is not well defined in Egypt. The heredity and environmental factors are the most important risk factors. Also, psoriatic arthritis is an important associated disease. The fact that it has no cure has important implications for how it should be viewed, prevented and treated. We recommend that more research should be carried out to understand the true epidemiological features of the disease in Egypt and its impacts on quality of life of the patients

Quantitative analysis of total proteins and carbohydrates in the digestive gland-gonad complex [DGG] and hemolymph of the freshwater prosobranch snail lanistes carinatus

Laboratory investigations were carried out to quantify the amount of total proteins, carbohydrates and reducing sugar in the hemolymph and Digestive Gland Gonad- complex [DGG] of infected and uninfected lanistes carinatus. Snails were naturally infected with two different types of trematode la val stages [rediae of gymnocepahalus cercaria and sporocyst of xiphidiocercaria], collected from the River Nile at Sohag governorate, Egypt. Analysis was carried out using an extraction of the DGGs tissue with buffer solution, while snails' hemolymph was applied directly. The results revealed that snail infection by rediae of gymnocephalus cercariae led to non significant increasing in both total carbohydrates and protein in hemolymph. However, infection by sporocysts of xiphidiocercariae caused a significant increasing only in hemolymph total protein. On the other hand, the amount of both reducing sugar and total proteins in DGG did not increase significantly whenever the infection caused by both types of trematode larvae. However, total carbohydrates in DGG increased significantly
