RESUMO
Nowadays, human scabies is more or less a public health problem in Egypt, particularly among school children. The results of this epidemiological studies among one hundred scabietic patients showed that (a) Scabies is widespread among children and youth particularly students (b) The sex and the site distribution are attributed to the risk factor of exposure to infestation (c) Scabies is a disease determined by Sociodemographic and Hygienic customs of the population with high familial incidence among the patients. The whole results were discussed on the light of the work done in Egypt and similar countries.

This study is a parasitological and clinical study on human scabies. This study was carried out on 100 patients attending the Dermatology Outpatient Clinic at Ain Shams University Hospitals, including 54 males and 46 females. All patients were subjected to detailed history taking, complete dermatological examination including Skin Scraping Test and Burrow Ink Test. Younger patients attended the dermatology clinic earlier than older patients, who usually delayed their visits until complications occurred. Scratching, erythematous papules and secondary infected lesions were the commonest lesions. The hands, wrist and external genitalia were the most frequently affected sites while the feet, ankles, knees and back were the least affected. Burrows could only be detected in 40% of patients. The most frequent sites were the web spaces, external genitalia, and finger sides. Burrow Ink Test was positive among 85% of patients with burrows while mites could be identified by Skin Scraping Test in 55% of patients. The most frequent clinical manifestations in the parasitologically positive patients were itching, burrows, and papules, and the most frequent sites were the web spaces, and the finger sides. Multiple sites affection was the characteristic feature among the preschool age children who represented 14% of cases.

Fleas are widely distributed and partially host specific ectoparasites of man and animal. The aim of this work was to study the role of fleas as one of the causative allergens of bronchial asthma in Egyptian patients. Two flea extract antigens were locally prepared. The first from the head and the salivary glands and the second from the abdomen. The sensitivity of the first antigen (head and salivary glands) was evaluated among a known group of flea bite allergic individuals and normal control group using two dilutions 1/50 and 1/100, and proved to be sensitive. Regarding bronchial asthma and fleas, two groups of individuals were examined, asthmatic patients and control ones, using flea extract antigen and common inhalant antigens as skin test as well as precipitin test using flea extract antigen. This test was done by prick method using the routine allergens (house dust, cotton dust, mixed mould, mixed pollens, cat hair, dog hair, wool, feather) and also with locally prepared two flea extracts: one was prepared from the head and salivary glands, the second was prepared from the abdomen. Out of these sixty asthmatic patients, only six (10%) gave positive skin reactions to the antigens of fleas extract. All the control gave negative skin reaction. The precipitin test using the double immuno diffusion method gave positive results with one case who showed reaction to flea extract skin antigen.

Mosquitoes are among the most annoying and important vectors of human and animal diseases as malaria, filariasis, yellow fever, rift valley fever...etc. In this paper, it was aimed to study the present status of species of genus Culex in the Suez Canal Governorates after the reconstruction and developmental projects. Five species of Culex were identified: C. pipiens, C. univittatus, C. antennatus, C. poicilipes and C. pusillus. The latter species was represented by two specimens. C. pipiens was the commonest species both indoors and outdoors. C. antennatus and C. poicilipes were found only outdoors. C. pipiens was found all the year round particularly in Spring. Other species were found in Spring and Autumn, except C. antennatus which was found in Summer as well. The results were discussed on the light of work done before.

Leishmaniasis presents a health problem in several countries of the old world. Cutaneous and now visceral leishmaniasis have been reported in Egypt. Visceral leishmaniasis has been reported in El Agamy, Alexandria. In this paper, the seasonal and daily hours of activities of both P. papatasi and P. langeroni as well as the blood preference were studied over two successive years. The results showed a bi-model or two peaks a year. The sandflies started to appear in the last of March or beginning of April and ended in last of November or beginning of December. The indoor hours of activity standard earlier and ended later than the outdoors one. The blood of the females of P. papatasi was mainly human blood, while that of P. langeroni was mainly non-human blood.

Indirect haemagglutination test (I.H.A.T.), Latex test (L.A.), and Complement Fixation test (C.F.T.), were performed on 100 serum samples obtained from Egyptian patients suspected clinically to have Hydatid disease and 50 healthy controls. The results of clinical, laboratory and serologic investigations revealed Hydatid infection in six cases.

This study was carried out to suggest criteria for diagnosing arthritis associated with schistosomiasis. 180 cases were classified into three clinical groups, 120 schistosomal arthritic group (I), 20 schistosomal non-arthritic (II), 20 arthritic non-schistosomal (III) and 20 controls (IV). Four tests were done to exclude other causes of arthritis namely, Erythrocyte sedimentation rate (ESR), Rose-Waaler test (RW) for rheumatoid factor (RF), antinuclear antibody test (ANA) and determination of serum uric acid (SUA) level. A history, clinical examination, urine and stool examination, intradermal test (IDT), indirect haemagglutination test (IHAT), circumoval precipitin test (COPT) and complete blood picture, were performed for all groups. 20 patients were selected randomly from group I and received praziquantel to be followed up 6 months later. Bilharzial ova were found in the excreta of group I and II. The percentage of positive IDT, IHAT and COPT in I & II was 90.8%, 90%, 88.3% and 85% respectively. Blood picture showed mild anaemia and from low to moderate eosinophilia. ESR was moderately raised. RF positivity was 6.6%, 10%, 65% and 5% in the four groups respectively. ANA positivity was 1.6%, 0%, 50% and 0% respectively. There was a marked improvement of arthritic manifestations after praziquantel in 90% of cases.
