1.  Effectiveness of itraconazole on clinical symptoms and radiologic findings in patients with recurrent chronic rhinosinusitis and nasal polyposis 
This study was done to evaluate the effect of itraconazole on clinical symptoms and radiologic findings in patients with chronic rhinosinusitis and nasal polyposis after surgery.
Materials and Methods:
In a clinical trial which was conducted in Alzahra and Kashani hospitals, from November 2011 to December 2012, 22 patients with recurrent postsurgical chronic sinusitis and polyposis entered the study. At the start of the study demographic data, subjective clinical symptoms (severity of rhinorrhea, nasal obstruction, hyposmia, and dyspnea), quality of life (QoL) by sinonasal outcome test-20 (SNOT-20), serum immunoglobulin E (IgE), and score of computed tomography (CT) scan (by Lund-Mackay) were recorded. Itraconazole (100 mg, twice per day) prescribed for 3 months and patients were followed in the 1st, 3rd, and 6th months. Liver enzyme tests and side effects were evaluated monthly.
Severity of rhinorrhea, nasal obstruction, hyposmia, dyspnea, and QoL (by SNOT-20) improved during 3 months of treatment. Serum IgE was 265 (±277) at the start of the study, and decrease to 193 (±183) after 3 month. After 3 month, Lund-Mackay score of CT scan lowered from 19 (±4) to 15 (±6) (P < 0.05). At the 6th month, severity of clinical symptoms except dyspnea and QoL were better than first evaluation.
This study showed the beneficial effect of 3-month itraconazole treatment on clinical symptoms and radiologic findings and QoL in patients with recurrent postsurgical chronic rhinosinusitis and nasal polyposis.

2.  Preventive effects of zinc sulfate on taste alterations in patients under irradiation for head and neck cancers: A randomized placebo-controlled trial 
Taste abnormalities are common among cancer patients after starting radiotherapy or chemotherapy. Considering the role of zinc and reports on its beneficial effects in taste perception, we evaluated the preventive effects of zinc sulfate on radiation-induced taste alterations.
Materials and Methods:
In a randomized, placebo-controlled trial, adult patients with head and neck cancers who were on schedule for radiotherapy, with or without chemotherapy, were allocated to receive zinc sulfate (50 mg, three times a day) or placebo; started with beginning of radiotherapy and continued for one month later. Taste acuity was determined by measuring detection and recognition thresholds for four taste qualities at baseline, at the end of radiotherapy, and a month later using the Henkin method.
Thirty-five patients (mean age = 59.2 ± 16.5, 60% male) completed the trial. The two groups were similar at baseline. After radiotherapy, and one month later, there was a significant increase in taste perception threshold for bitter, salty, sweet, and sour tastes in the placebo group (P = 0.001). In those who received zinc, there was only slight increase in threshold for perception of the salty taste (P = 0.046). No relevant side effects due to zinc sulfate were reported.
Zinc supplementation in head/neck cancer patients under radiotherapy can prevent radiation-induced taste alterations. Further studies with longer follow-ups and with different doses of zinc supplementation are warranted in this regard.

3.  Hearing Impairment in Congenitally Hypothyroid Patients 
Iranian Journal of Pediatrics  2012;22(1):92-96.
Thyroid hormone is necessary for normal development of the auditory system. The aim of this study was to investigate the rate of hearing impairment in congenitally hypothyroid (CH) patients, and its relation with factors such as CH severity and age at starting treatment, during CH screening program in Isfahan.
Hearing acuity was assessed in two groups of children with (94 patients aged 4 months – 3 years) and without CH (450), between 2000-2006. Otoacostic emission (OAE) was performed by a two step method. After two tests without OAE signals bilaterally, they were referred for auditory brainstem response (ABR) test. Subjects with both OAE and ABR abnormal test results were considered to have hearing problem. Obtained data was compared in case and control group and also CH patients with and without hearing impairment.
Three (3.2%) of patients and 1 of control group (0.2%) were diagnosed with sensorineural hearing loss. The rate of hearing loss was not different significantly in two studied groups (P>0.05). There was no difference between age of starting treatment and first T4 and TSH level in CH patients with and without hearing loss (P>0.05). CH neonates with hearing impairment had thyroid dyshormonogenesis according to the follow up results.
The rate of hearing loss was low among our studied CH patients. It may be due to proper management of CH patients. In view of the fact that all CH neonates were dyshormonogentic and considering the relation between certain gene mutations and hearing impairment in CH patients, further studies with larger sample size, with regard to different etiologies of CH should be investigated to indicate the possible gene mutations related to hearing loss in CH.

4.  A Study on Body Mass Index, Blood Pressure, and Red Blood Cell Indices in New Entering Students of the University of Isfahan 
Obesity and increased blood pressure are identified as risk factors for cardiac and pulmonary disorders. On the other hand, iron deficiency (another preventable disease) is common in adolescence and considered as associated with health impairment. The present study evaluates body mass index (BMI) and its association with blood pressure and hematological indices in freshman students entering the University of Isfahan in 2009.
All the 1675 students who entered the University of Isfahan in September 2009 were examined. Height, weight, BMI, blood pressure, hemoglobin (Hb) and red blood cell (RBC) indices of these students were measured. The prevalence of high blood pressure, its association with BMI and the relation between BMI and anemia, iron deficiency and educational achievement were assessed.
All participants, including 514 males and 1161 females, went under clinical observations. The average age was 20.7 ± 3.8. year Among the students, 18.2% of males and 20% of females were underweight. High systolic blood pressure was more common in the students with BMI > 25 kg/m2 (p < 0.001). Anemia was seen in 8.7% of females. In males, however, a relation between anemia frequency and BMI < 18.5 kg/m2 was more distinct (p = 0.002). There was no association between anemia and students’ average test scores.
High incidence of abnormal BMI in the study population, and its association with systolic blood pressure indicate the importance of nutritional guidelines and counseling programs for freshman students. On the other hand, high incidence of anemia in this population ascertains the necessity of anemia screening programs before academic studies.
