Abstract
Low back pain is among the most frequent medical complaints and a major public health problem. 1.7 percent of cases are caused by herniated disc, 20 percent of which require interventional treatment. Percutaneous laser disc decompression (P.L.DD) can be considered as an effective therapeutic alternative in certain cases.
Materials and Methods: To determine the efficacy of this method in Iran in patient's with low back pain due to disc herniation, 40 patients according to medical history, physical examination and MRI findings were selected for this study. Patients who had canal stenosis, marginal, osteophyte, advanced disc dehydration, ruptured posterior ligament and other contraindication were excluded. CT scan was used only for needle navigation. After proper positioning of needle, nucleous pulposus was evapourated with Nd-YAG laser. Total energy was 1200-1600j. The procedure was done out patient and follow up has been done at 1 day, 1 week, 1,3, 6 and 12 months.
Results: There was no serious complication. 80 percent of patients in one-year follow up showed significant clinical improvement.
Conclusion: Our findings suggests that percutaneous laser disc decompression can be considered as an effective alternative method of treatment for disc herniation and patient selection is the critical factor which determines success rate.

Abstract
Background: This investigation was conducted in order to study angiographic findings in patients with cerebral aneurysm.
Materials and Methods: The study conducted on 136 cases of ruptured cerebral aneurysms between 1995-2000 confirmed by means of 4-vessel cerebral angiography to get an insight to racial, geographic and environmental factors predisposing to the occurrence of subarachnoid hemorrhage and aneurysm formation. Results: The data analysis revealed the following
Results: 58% of the population comprised of male and 42% female with a mean age of 46 years. 89% of the aneurysms were found in the anterior circulation and 11% occurred in the posterior cerebral circulation. The most common site in both the sexes was the anterior communicating artery. 9.6% of the patients displayed two separate aneurysms. 5.2% of the aneurysms were found to be giant aneurysms and 3% of the patients had fusiform aneurysms.
Conclusion: The low average age, a predilection in male population and the prevalence of aneurysms at carotid and middle cerebral artery bifurcation and the distal branches of anterior cerebral artery and a higher incidence of anterior communicating artery in women were the findings observed in this study.

Abstract
Background: Imaging abnormalities in the paranasal sinuses are regularly noted as incidental findings on MRI, however, little is known about their prevalence in the Iranian population. The purpose of this study was to classify these findings in the paranasal sinuses as seen on MRI and to investigate the prevalence, according to site and type of paranasal abnormality.
Methods: In this cross-sectional study, the T2-weighted axial MRI of 256 patients with diseases unrelated to their paranasal sinuses were reviewed between May 2002 and June 2003. The findings were categorized according to the anatomic location and the imaging characteristics of the abnormality. The abnormalities recorded included total sinus opacification, mucoperiosteal thickening >5mm, air fluid levels and retention cysts or polyps. Unilateral or bilateral involvement and septal deviation were also noted. A sinus was considered normal if it was fully aerated and no soft-tissue density was apparent within the cavity.
Results: Among our cases, 111 (43.5%) were male and 145 (56.5%) were female. Of these patients, abnormalities in one or more of the sinus groups were found in 110 subjects (42.9%), 55.5% of which were male and 44.5% were female (P=0.001). Maxillary sinus abnormalities were observed in 66.4% of the patients, while ethmoid sinus abnormalities were found in 63.6%. Of the ethmoid abnormalities, 21% were found in the anterior section, 9% in the middle ethmoid, and 8% in the posterior ethmoid. The most common abnormality found was mucosal thickening. Among our cases, 23.4% had septal deviation, which was significantly higher among those with sinusitis (29% versus 19.1% P<0.01).
Of those patients with sinus involvement, 16% were involved in the sphenoid sinus and 5% in the frontal sinus. The results obtained from the patients with sinus abnormality revealed that 85% suffered from cough, nasal obstruction, runny nose, facial pain and post nasal discharge and 24% had been diagnosed with chronic sinusitis by physician.
Conclusion: Our results showed that there was a high rate of incidental abnormalities in the paranasal sinuses that are unrelated to the patient's presenting problems.

Abstract
Background: Among patients who have sensorineural hearing loss of unknown etiology,
diabetes is one of the diseases to be routinely investigated. The relationship between
diabetes mellitus and hearing loss is still controversial. The purpose of this study was to
examine the prevalence of sensorineural hearing loss in patients with insulin-dependent
diabetes mellitus (IDDM) compared to control group.
Methods: In a cross-sectional study pure tone audiometry (PTA) and speech audiometry
was performed in 62 patients with insulin-dependent diabetes mellitus (IDDM), aged under
40 years, and in 62 randomly selected age-matched non-diabetic control subjects. Subjects
with otological and other metabolic diseases were excluded from the study. We applied the
SPSS.10 statistical analysis software Chi-square and student’s test.
Results: Statistical analysis showed that the hearing of the diabetic patients were
significantly worsen than the control subjects. The hearing level tended to be worsen in the
diabetic patients than that in control subjects, but the differences were statistically
significant only at frequencies of 250,500, 4000 and 8000 Hz (p<0.05). There wasn’t
statistical significant difference between sex in two study groups (p>0.05). The mean
duration of diabetes was no statistically significant with hearing loss (p>0.05). The
frequency of complications such as retinopathy, nephropathy, and neuropathy in the
diabetic groups had no correlation with speech threshold (p>0.05). There were no
significant differences between speech reception threshold, speech discrimination score
and acoustic reflex in two groups.
Conclusions: We conclude that type I diabetes mellitus can cause sensorineural hearing
loss.
