Solvent exposure can affect human health. It can cause different effects in different part of the body. One of the most important side effects is neurobehavioral symptom including mood disorders, short memory, and tiredness. To determine the frequency of neurobehavioral effects in patients of a car producing plant in Tehran and comparing them with other workers in the same plant whom was not being exposed to such solvents. All of car painters (78 persons) as our case group and 83 non-painters as our control group were selected by simple random sampling and neurobehavioral abnormality was assessed by Q16 questionnaire. Neurobehavioral disorders based on above questionnaire was observed in 46% of car painters vs. 36% of non-painters (P=0.10). The significant differences were observed in perspiration without any particular reason (Q8) and feeling irritated without any particular reason (Q4). There was not a significant difference in observed frequency of neurobehavioral abnormalities in patients vs. non-painters, however both of these frequencies were higher than expected frequency reported in other reports.

Hydatidosis is a parasitic infection mostly in found in the liver and lung due to echinococus species. But occurrence in other locations is possible. Purpose of this report is to describe a case of bilateral Hydatid cyst in ovaries. Clinical findings with this uncommon location are poorly specific and diagnosis required histologic examination after surgical removal. Imaging and serology is useful to differentiate Hydatid cyst from benign and malignant tumors. This obligatory to examine lung and liver as the main sites of cyst when you are being faced with unusual location of Hydatid cyst especially in endemic area such as Iran. Our patients was a 35 years old woman with history of 4-month abdominal pain in left and right lower quadran. Sonography showed two cysts in adenexal lesions after surgical removal, they were sent to pathology lab. Hydatic cyst membrane was seen in histologic examination of two cystic masses.

The Iranian elderly population is rapidly growing. Currently more than 5 million Iranians are over 60 years of age which corresponds to nearly 7.26 percent of the population of the country. It is estimated that more than 10 percent of the population of the country will be elderly in the forthcoming twenty years. Structural and physiological changes which occur in the elderly cardiovascular system include: stiffness of the vasculature, decreased relaxation capacity of the heart during diastole, decreased efficiency of cardiac contraction during exercise, weakened heart muscle response to stimulation by adrenaline, and orthostatic hypotension. In the elderly people we are confronting with increased frequency of cardiovascular diseases especially myocardial infarction, stroke, isolated systolic hypertension, calcific aortic stenosis, orthostatic hypotension, and syncopal attacks due to sick sinus syndrome, complete heart block, atrial fibrillation or other rhythm disorders. Alteration in cardiovascular status in the elderly has undesirable effects on their quality of life and longevity. Myocardial infarction is the most common cause of death in the elderly however cardiac arrhythmias and valvular heart disease are other important cardiovascular disease in the old people. Diagnosis of these disorders in the elderly requires special consideration since coexistence of structural/functional changes in the old age with cardiovascular disease would alter the classic features of these disorders and result in delay in their appropriate management. Biological aging as evaluated by reduced telomere length has a strong impact on the incidence of cardiovascular disorders especially coronary heart disease and chronic heart failure. This phenomenon could possibly explain interindividual susceptibility to cardiovascular disorders.

Autosomal recessive primary microcephaly; MCPH is a rare neurologically condition observed in new born at the birth. Most patients suffer from moderate to severe intellectual disability. In this review article, we introduce MCPH disorder; include all of the chromosomal locations, kind of MCPH genes and numbers of mutations, functional efficacy, how to identify the genes separately and diagnostic algorithm of articles and data base such as OMIM, HGMD. 23 locations genes (MCPH1-23) have been recognized causes primary microcephaly in different population, so far. Function of them is to correct orientation of mitosis spindles, duplication of DNA, organization and function of centrosome, transfer of vesicles, transcription regulation, response to DNA lesion, etc. According to investigations, MCPH in Iran and Pakistan population is common because of more consanguinity marriage. MCPH1 and MCPH5 genes are more common in Iran. Recent advances in molecular biological techniques and animal models have helped to identify the genetic cause of microcephaly and open up the horizons for researchers in the field, and also elucidating of the underlying molecular mechanisms will improve our understanding of the structure and function of the brain.
