Associations between hearing and blood lipids have been the focus of scientific inquiry for more than 50 years. The aim of the present study is to evaluate the association between hyperlipidaemia among patients presented with sudden sensorineural hearing loss compared to normal controls. A case control study concerned with 22 patients presented with sudden sensorineural hearing loss who underwent lipid profile evaluation. The lipid profile of these patients was compared with corresponding results of 55 age matched persons (volunteers) with normal hearing. These patients were collected from the Out Patient Department of ENT at Al-Jamhory Teaching Hospital, Mosul/Iraq and private clinic of the author for the period from February 2011 to July 2013. The average age of patients was 44.7 years with a range of 26-65 years. The peak age incidence was in the 5(th) decade of life. The study included 11 male patients (50 %) and 11 females (50 %). Meanwhile, the average age of the control group was 41.7 years with 25 (45.5 %) males and 30 (54.5 %) females. Statistical analysis showed that there was significant difference between the means of lipid profile and blood sugar of the patients and the control group apart from HDL where there was no significant difference. In conclusion, hyperlipidemia seems to be significantly associated with the occurrence of sudden sensorineural hearing loss according to this study.

The current research included obtaining the best performance specifications for a silicon device with a mono-crystalline type pn junction (pn–Si). A simulation of the device was performed by the use of a computer program in one dimension SCAPS-1D in order to reach the optimum thickness for both p and n layers and to obtain the best efficiency in performance of the pn-Si junction. The optimum device efficiency was eta (η) = 12.4236 % when the ideal thickness for the p and n layers was 5µm and 1.175µm, respectively (p=5 µm and n=1.75µm).      The research included studying the effects of different spectra of solar illumination using simulation of the device; the usual solar spectrum AM1_5 G1 sun. Spectrum, Black body spectrum, White spectrum constant photon flux, White spectrum constant photon power, Monochromatic spectrum constant flux, and Monochromatic spectrum constant power. The highest efficiency was obtained from the monochrome spectrum with constant power (eta (η) =22.4338 %). The effects of different temperatures on the device was studied on 250K, 300K, 350K, 400K, and 450K. The highest efficiency was revealed for Monochromatic spectrum constant power (eta (η) =24.5381 %) when the temperature was 250K.

Background: Many pediatric patients present to the otolaryngologist with snoring and obstructive sleep apnea due to adenoid enlargement, which requires adenoidectomy. Due to the adenoid importance for immunity in early childhood, and the risks of anaesthesia and operative complications, an alternative medical treatment has been considered. Aim: To compare the effect of mometasone spray and montelukast, each alone or in combination on the symptoms and size of obstructive adenoid in children aged 3-13 years. Patients and Methods: A prospective randomized non-blinded study was conducted at Al-Jumhoori Teaching Hospital from August 2019 to November 2020. It included 95 patients (males 47, females 48) with nasal symptoms attributed to adenoid enlargement; they were randomly assigned to three groups; group (I) taking mometasone , group (II) taking montelukast , and group (III) taking both. Treatment continued for two months. Clinical scores were taken after two months of treatment, and then one month after cessation of treatment. Results: In group I there was improvement at three months of nasal obstruction and adenoid size. In group II there was improvement at three months of cough only. In group III there was improvement at three months of nasal obstruction, cough and adenoid size. Conclusions: There is significant improvement of adenoid size and symptom score with mometasone and montelukast, each alone or in combination. Mometasone has a better effect on adenoid size and symptoms than montelukast at two months, with less recurrence of adenoid size and symptoms one month after cessation of treatment. Combined therapy of mometasone and montelukast showed marginal improvement over mometasone alone at two months. At three months, there is no advantage of combined treatment over mometasone alone.

Objectives: The aim of the present study is to evaluate the aetiology of secondary (referred) otalgia. Patients and methods: A case series study of 79 patients clinically diagnosed as secondary otalgia, collected from the Outpatient Department of ENT at Al-Jamhory Teaching Hospital, Mosul/IRAQ, and private clinics, for the period from Jan. 2010 to Sept. 2011. Results: The average age of the patients was 33.3 years with a range of 4-80 years. The peak age incidence was in the fourth decade of life. The study included 34 male patients (43.1%) and 45 females (56.9%) with a ratio of 1:1.3. Temporomandibular joint dysfunction was found to be the main cause of secondary otalgia (37.9%). Pharyngitis (24%), dental pain (17.7%) and cervical spine pain (7.6%) came next in that order. Conclusion: Temporomandibular joint dysfunction, pharyngitis, dental problems and cervical nerve root pain were the commonest causes of secondary otalgia. Moreover, upper aerodigestive tract malignancies should be considered in differential diagnosis.

Objectives: The aim of the present study is to evaluate the efficacy of septoplasty in relieving symptoms and problems attributed to septal deviation including: nasal obstruction, recurrent sinusitis, recurrent /or chronic pharyngitis, epistaxis and snoring. Methods: This case series included eighty four patients with septal deviation severe enough to necessitate surgical intervention (severe nasal obstruction not relieved by medical treatment). The study was carried out at Al-Jumhori Teaching Hospital from July 2009 to Oct. 2010. All patients were suffering from nasal obstruction. Twenty seven patients had recurrent sinusitis, seven recurrent or chronic pharyngitis, five recurrent epistaxis, and snoring was found in four patients. The mean follow-up was six months with a range of 3-15 months. Results: The mean age of our patients was 27.3 years with a range of 15-52 years. The study included 52 males (61.9%) and 32 females (38.1%) with a ratio of 1.62:1. Sixty eight patients (80.9%) reported good improvement in their nasal obstruction after surgery. Improvement in recurrent sinusitis, chronic pharyngitis, epistaxis and snoring was 55.5%, 28.5%, 80% and 25% respectively. Conclusion: We conclude that septoplasty is indicated mainly to relieve nasal obstruction resulting from moderate to severe nasal septal deviation. Other conditions which are commonly attributed to septal deviation including recurrent sinusitis, chronic pharyngitis, epistaxis and snoring are not necessarily cured by this surgery.
