“…The common abundance of subterranean termites is in arid and semiarid areas of upper Egypt. However, these termites prefer to infest the places that have a high moisture content and warm temperature (Hafez 1980;Moharram et al 1992). The sand termite, Psammotermes hypostoma Desneux, can do great damage to unprotected buildings, other wooden structures, and almost anything containing cellulose.…”

Abstract:The sand termite, Psammotermes hypostoma Desneux is a major pest in the New Valley Governorate, Egypt. Great efforts have been taken to control the pest. We evaluated the toxicity of four selected neonicotinoids [acetamiprid (20% SP), imidacloprid (20% SL), thiamethoxam (18.6% SC), and thiamethoxam (40% WG)], and one organophosphate pesticide [chlorpyrifos (48% EC)] against P. hypostoma workers. The investigation was done under field conditions, using the palm fronds method. However, the reduction percentages in palm fronds was recorded as the height of the sandy clay formed by termite workers on palm frond surfaces, when the fronds had been treated with a different concentration of each pesticide. The results were recorded after 15, 30, 45, and 60 days. Chlorpyrifos (48% EC) was considered the most potent pesticide among all the pesticides tested, but acetamiprid (20% SP) was considered the most toxic among the neonicotinoid pesticides tested. Moreover, the formulation of thiamethoxam (18.6% SC) was more powerful than thaimethoxam (40% WG). Furthermore, the reduction percentages on palm fronds increased significantly with an increase of the exposure period (from 15 to 60 days), as a result of the surface foraging activity of the sand termite workers. These results are given as unique and encouraging trends in controlling sand termites in Egypt.

“…Similar results were seen in study conducted by Moharram et al who in their study on 124 patients found that the disease was more prevalent among persons between 21-30 years. 5 Aneja et al in their study found the disease to be more prevalent in females than males in the age group of 31-40 years. 6 In the present study most (46.1%) of the patients reported to us in the summer season indicating seasonal preponderance of the disease.…”

Background: Otomycosis is the fungal infection of the external ear with bothersome symptoms. The target of the study was to verify the frequency and identification of fungi responsible for the otomycosis and to give the most appropriate treatment. The aims and objectives of the study was to study clinical profile, causative fungal organisms of otomycosis, detect in vitro efficacy of various antifungal solutions against the fungi detected and to establish clinical efficacy of various topical antimycotic solutions in otomycosis in Kashmir. Methods: This study was conducted in the Department of ENT, GMC, Srinagar from February 2014 to July 2015. 152 clinically suspected otomycosis patients were subjected to mycological tests including Gram staining, 10% KOH staining, GTT, SDA and CBL stain to identify the organism. Clotrimazole, terbinafine, lulliconazole, sertaconazole and combination of 1% clotrimazole, chloremphenicol, beclomethasone were given randomly in equal number of these patients. Patients were followed for 4 weeks and results of different antifungals were evaluated clinically. Results: Out of 152 patients 61.8% were females and most of the patients belonged to age group of 25-34 yrs. Most of the patients reported in summer season. Otalgia and itching was the most common symptom. Aspergillus was the most common species identified whereas Candida albicans was the most common individual organism isolated. Lulliconazole was most effective drug whereas combination of 1% clotrimazole, chloremphenicol, beclomethasone was least effective. Conclusions: Clinical suspicion of otomycosis is important to prevent unnecessary use of antibiotics. Diagnosis of otomycosis is usually made by clinical findings with pruritis being most common symptom followed by otalgia. Invitro sensitivity test is of great importance to choose the most active antifungal agents. Patients are advised to avoid removing of ear wax by stiff materials.

“…These findings were relatively close to a previous study in Egypt that recorded a male to female ratio of 9:1 with age range >40 years (ALHussaini et al, 1994). Moreover, the study of Moharram et al (1999) revealed that fungal keratitis affected males more than females, and was more frequent in those aged from 20 to 50 years. It is evident that social hygiene parameters had a great effect on the spreading of infectious human mycotic corneal ulcers.…”
