Background & Objectives: Recurrent respiratory papillomatosis (RRP) is the most common benign laryngeal tumor and the second common cause for hoarseness in children. Despite its omplete benign histology, it has a great tendency to spread through the respiratory track and frequent recurrences may occur following surgery, possibly due to the virus survival in apparently healthy adjacent tissues. According to the most recent evident experiences, the treatment of choice for RRP disease is repetitive resections with CO2 laser. The present study evaluates the efficacy of adjuvant medical therapies for eradication of this disease in affected children.
Methods : This was an experimental study with sequential control (self-control). The subjects were children who referred to ENT-H&N surgery dept. of Hazrat-e- Rasoul hospital in Tehran between Mar 1998 and Mar 2001 with chief complaint of hoarseness and respiratory obstruction. Among these children patients with confirmed diagnosis of RRP were selected as study samples and the effect of acyclovir and alpha-interferon combination in reducing the severity and recurrence of RRP was evaluated.
Results: Totally 18 patients entered this study (10 (55.5%) females and 8 (44.5%) males). The mean age of the patients was 6.5 and 94% of them were the first child of young mothers (under 25 years of age). The signs of respiratory obstruction in most of the cases with a mild to moderate severity was the main cause of referral in 45% of the subjects. Laryngeal lesions were mostly superficial and limited to glottis region. Severity and spread of RRP disease was greater in children under 3, which led to tracheotomy in 3 of them. The combined administration of alpha-interferon and acyclovir, made a significant reduction in disease severity and spread in 55.6% of the patients.
Conclusion : The findings of this study indicated that combination of acyclovir and alpha-interferon can be effective in reducing RRP recurrences and severity. Nevertheless, because of small sample size(due to rarity of RRP), Further multi-institutional studies are required to obtain a greater sample size and more valid results.

Background & objectives: Hypertension is a disease with high prevalence and complications and unfortunately the freatment of which is not desirable in many communities including ours. The aim of this study is to assess the therapeutic diet giving and level control of HTN in patients with Hypertension who refered to Ardabil Boali Hospital emergency room and out patient Clinic room.
Methods: This study was performed on 200 patients who refered to the emergency room and out patient Clinic in Ardabil Boali Hospital from 2003 to 2004 due to high blood pressure. In this study, blood pressure and other factors such as sex, age and the therapeutic modality including compliance to theyapy and kind and quality of drugs were determined, then the data was analyzed by using descriptive statistics.
Results: Of 200 patients only 1% did not take drug 59.5% of patients were on monotherapy and 39.5% took two or more drugs 33.5% were on Beta blocker (Atenolol) and 11% on ACE inhibitor (Enalapril). Among patients on combination therapy the highest prevalence was B.bloche and ACE.I 40%, and the least one prevalence was diuretic and CCB (2%). All patients on diuretic were pre hypertensive whereas the majority of patients on CCB had stageII hypertension. In patients on multi drug therapy all patients on diuretics + CCB were pre hypertensive but 57% of patients on ACEI + CCB or ACE.I + diuretic had stageII hypertension.
Conclusion: In this study for combination therapy Diuretic and CCB had the best result in controlling hypertension.

Background & objectives: Stroke is third leading cause of death and disability in the most of human communities. Several experimental studies have shown that combination therapy with drugs that act via different mechanisms can produce amplified protective effects. We examined the effects of combination therapy with candesartan and alpha tocopherol against cerebral ischemia.
Methods: Male Sprague-Dawley rats were divided into five groups (n=24): sham, control ischemic, candesartan treated (0.3 mg/kg), alpha tocopherol treated (30 mg/kg) and combined treated ischemic groups. Transient focal cerebral ischemia was induced by 90-min-long occlusion of the left middle cerebral artery followed by 24-h-long reperfusion. Neurological deficit score was evaluated at the end of the reperfusion period. Thereafter, the animals were randomly used for measurement of the infarct volumes and investigation of ischemic brain edema formation using a wet/dry method.
Results: Induction of cerebral ischemia produced considerable brain infarction in conjunction with severely impaired motor functions and edema formation. Combined treatment with candesartan and alpha tocopherol significantly reduced the infarct volume and lowered the water content in the ischemic lesioned hemisphere. These effects on brain edema and oxidative stress biomarkers were significantly more than the monotherapy with candesartan.
Conclusion: The combination therapy with candesartan and alpha tocopherol can noticeably decrease ischemic brain injury and attenuate edema formation likely via increasing the antioxidant activity.

Background & objectives: Ischemic stroke has complex pathophysiology and its treatment with single neuroprotective drugs has so far failed. Combination therapy could produce amplified protective effects via different mechanisms. We examined the neuroprotective effects of enalapril and/or alpha tocopherol against sensorimotor dysfunctions of ischemic stroke.
Methods: Forty male Sprague-Dawley rats were randomly divided into five groups (n=8): sham, control ischemic, enalapril (0.03 mg/kg), alpha tocopherol (30mg/kg) and enalapril plus alpha tocopherol treated groups. Transient focal cerebral ischemia (90 min) was induced by occlusion of the left middle cerebral artery that followed by 24 h reperfusion periods. Infarct volumes were detected by TTC coloring technique and sensorimotor dysfunctions investigated by rotarod, grip strength and hotplate tests.
Results: Induction of cerebral ischemia in the control group produced severe neurological sensorimotor deficits in conjunction with considerable cerebral infarctions. Compared with the enalapril or alpha tocopherol groups, the combined treatment significantly improved neurological motor and sensory functions (p=0.038 and p=0.034, respectively) and also reduced the infarct volume (p=0.032).
Conclusion: Administration of alpha tocopherol increased protective effects of enalapril. Enalapril combined with alpha tocopherol can produce an augmented protection against ischemic brain injury, and improvement in sensorimotor dysfunctions.

Background & objectives: In recent years, the hypothesis of using anti-androgens has been increasingly addressed in the treatment of acne in women. One of these drugs is flutamide, which there is no strong evidence of its efficacy in treatment of acne in women. The aim of this study was to compare the effect of combination therapy of flutamide-cyproterone compound with flutamide-doxycycline in severe type of acne in women.
Methods: In an interventional study, patients were divided in to two groups. One group (n=30) received flutamide - cyproterone compound and another group (n=30) received flutamide-doxycycline which were followed for six months. Both groups also received 1% topical clindamycin twice a day. Counting the number of lesions, changes in severity index and grading of acne were used to evaluate the patients. Patient satisfaction was also evaluated.
Results: The mean age in the flutamide-doxycycline group was 19.4±4.67 and in the flutamide-cyproterone compound group was 19.06±11.3. This difference was not statistically significant. The mean of the acne severity index at the onset of intervention between the two groups was not significant (p= 0.7). The mean of the acne severity index at the start of treatment in the flutamide-doxycycline group was 306.07±155.46 and at the end of treatment reached to 19.18±19.5, and also in the flutamide-cyproterone compound group, decreased from 293.21±15.21 to 10.5±21.8 at the end of treatment. This difference was not statistically significant (p=0.1).
Conclusion: Both therapeutic regimen were effective in the treatment of severe type of acne and can possibly be used as an alternative treatment for severe acne.
