Shervin Pejhan Ahmad Shekarchizadeh   Abstract   Malacoplakia is a rare chronic inflammatory disease associated with infection and immunosuppression, and very few occurrences have been reported in the bone. The authors describe the case of a 22-year-old woman with paraplegia and urinary and fecal incontinence whose thoracic spine Magnetic Resonance Imaging suggested a tumoral or extensive inflammatory process in the body of the 8th, 9th and 10th thoracic vertebrae. On histology, however, the area turned out to be malacoplakia of bone. Although microbiologic cultures and polymerase chain reaction were negative for Mycobacterium tuberculosis, the lesion demonstrated regression following treatment with anti-TB regimen which had been started because of clinical suspicion.   Malacoplakia of bone vertebra rare site 2008 5 01 52 54 http://mjiri.iums.ac.ir/article-1-67-en.pdf

Some risk factors have been implicated for   ALS such as exposure to high magnetic fields, and trace elements like selenium, cadmium and lead. Afew studies have been carried out throughout the world to evaluate   the prevalence of ALS among veterans. This study was aimed to evaluate ALS frequency among Iran – Iraq war veterans.   Methods: Medical records of 52580 veterans were studied and those with suspected   neuromuscular disorders were referred to a blind neurologist. ALS was verified according to World Federation of Neurology criteria. Student t-test and chi-square test   were used for analysis and a P value less than 0.01 was considered significant.   Results: Eleven definite ALS and two possible ALS cases were identified among   the subjects. The mean age of onset of the disease was 43.7±9.7 years. All subjects had   a record of at least three months involvement in action and symptoms began to show   up after 16.5±3.6 years. The mean interval between exhibition of symptoms and the   definitive diagnosis of the disease was 16.5 months.   Conclusion: The prevalence of ALS in our population was significantly greater   than that of international surveys (P<0.01). The onset of the disease occurred at a significantly lower age than typical ALS (P<0.01). Military service might therefore be a   risk factor for ALS.   amyotrophic lateral sclerosis military service 2008 5 01 47 51 http://mjiri.iums.ac.ir/article-1-66-en.pdf

Aboulfazl Ghorbani Manijeh Ghods   Abstract   Background: Diarrhea has been recognised as a major public health problem worldwide. Aprospective study was performed to determine the etiology, seasonal and age prevalence, relevant laboratory investigations, sensitivity of isolated microorganisms to current medication, and practical approaches to the diagnosis and management of diarrhea in Iran, as a developing country.   Methods: All infants and children under age five (n=825, mean age 18.9) admitted to   Tehran Children’s Hospital, Tehran, with diarrheal symptoms during the period of April   2005 to March 2006 were included in the study 371 approximately age-matched controls (mean age 19.1 months) from the same hospital but not having diarrhea formed the control group.   Results: The most frequent isolated pathogen was Escherichia coli (18.9%), followed   by Shigella spp (0.7%), and Salmonella spp (0.4%). Prevalence of diarrheic children with   either isolated or non-isolated pathogens were 66.5% in the colder seasons and 54.4% in warm seasons. E. coli was more prevalent in children younger than two years old while Sigella spp and Salmonella spp were common to all ages. Fecal leukocytes were associated with 100% of isolated Escherichia coli, 19.4% of non-isolated organisms, 2.5% of Shigella spp, 0.5% of Salmonella spp and none in controls. Escherichia coli was also associated with fecal red blood cells (29.4%), as were Shigella spp (83%) and Salmonella spp (33.3%). White blood cell counts, polymorphonuclear cells, band cells, erythrocyte sedimentation rate and C-reactive protein measurements had no diagnostic value. Amikacin was the global choice of antimicrobial treatment for Shigella spp in (99%) of cases and for Escherichia coli in (91%) of isolated cases. Only 70% of patients infected by Salmonella showed sensitivity to Gentamycin.   Conclusion: Diarrheal diseases in either isolated or non-isolated pathogens were more   prevalent in the colder seasons and in children younger than two years of age. For differentiation of bacterial from non-bacterial etiology, we had to wait for laboratory reports and then decide for antibiotic administration. The antibiotic most sensitive to Echerichia coli and Shigella was Amikacin, and Gentamycin was the most sensitive drug for Salmonella.

Hossein Shabahang Helen Sahebghalam   Abstract   Background: Due to the high incidence of breast cancer and the effect of its early   diagnosis on decreasing morbidity and mortality, we used the Gail model to study   breast cancer risk in Iranian women.   Methods: This study was done in a simple randomized way. Participants were 2000   Iranian women older than 35 years old. The questionnaire consisted of demographic   data such as age, race (optional ) marriage status , level of education and standard questions of the Gail model. Gathered data were given in http://bcra. nci. nih.gov/brc. The breast cancer risk was calculated within the next 5 years and within the 90 years life   span. The statistical analysis was done by SPSS software.   Results: Mean age of women in the study was 47.95 years .50% of women had their   menarche at/older than fourteen years of age. 50% of women had first childbirth in   their twenties. 87% had a negative family history of breast cancer. 94% had no history   of breast biopsy. Of the remaining 6%, no tissue atypia was reported. In the present   study, breast cancer risk within 5 years was 0.92% and the breast cancer risk within 90   years of life was 9.14%. 7% showed risk of more than 1.67% in the Gail model. The   age ranged between 55-65 years in this high risk group.   Conclusion: In our study of breast cancer risk in Iranian women, breast cancer risk   was lower than the control group in the Gail model estimate for 5 years and a 90-year   life span. (0.92% versus 1.02% , 9.14% versus 11.21%). The differences were statistically significant (p<0.001).   breast cancer risk assessment Gail model high risk. 2008 5 01 37 39 http://mjiri.iums.ac.ir/article-1-64-en.pdf

Seyed Mohammad Fereshtehnejad Neda Khalili Malihe Naghavi Hooman Yahyazadeh   Abstract   Background: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality, and is an important health economic problem. Since 1960, there has been an increase in mortality associated with COPD, especially in men. Acute exacerbations form a major component of the socioeconomic burden of COPD which mainly results in long-term hospitalization. Despite the high number of COPD-related hospitalizations, relatively little is known about the mortality rate and related determinants of patients hospitalized for this acute deterioration in the clinical course of COPD. The aim of this study was to evaluate the factors affecting duration of hospitalization in Iranian patients with COPD.   Methods: This cross-sectional study was performed on 68 COPD patients who were   hospitalized in Rasool-e-Akram hospital in Tehran, Iran for the period 2005-2006. During   hospitalization, patients’ chief complaint, symptoms and signs, results of physical examinations,spirometry, arterial blood gas (ABG) and ICU admission were recorded. Data were analyzed using Independent T-test, One Way ANOVAand Correlation tests.   Results: The patients were 41(60.3%) males and 27(39.7%) females with the mean age   of 69.7(SD=13.52) years. The mean duration of hospitalization was 11.82(SD=5.49) days and 3(4.4%) patients died. The family history of pulmonary disease (P=0.018), habitual snoring (P=0.031), and mean baseline arterial PaO2 (P=0.010, r= -0.361) were determined as factors affecting duration of hospitalization. On the other hand, other factors such as smoking (P=0.992), patient’s gender (P=0.735) and spirometric indices did not significantly associate with duration of hospitalization.   Conclusion: The fact that people hospitalized with COPD have a subsequently increased risk of death compared with those not hospitalized suggests the former are an atrisk group and shows the importance of factors affecting duration of hospitalization. Our results show that more attention must be paid on habitual snoring and low arterial pO2 which may have potential effects on duration of hospitalization in COPD patients.   chronic obstructive pulmonary disease (COPD) hospitalization morbidity 2008 5 01 29 36 http://mjiri.iums.ac.ir/article-1-63-en.pdf

Foroogh Bahreini Haydeh Samiee Bita Eslami Afsaneh Tehranian Somayeh Sabet   Abstract   Background: Hysterectomy is the second most common major surgery procedure   done after cesarean section by gynecologists in many countries and the most common   procedure is total abdominal hysterectomy (TAH). The incidence of laparoscopically assisted vaginal hysterectomy (LAVH) performed for benign lesions has progressively increased in recent years. Our objective was to compare the relative advantages and disadvantages of LAVH and TAH procedures.   Methods: A clinical trial was performed on patients who were candidates for hysterectomy with benign reasons in Arash hospital from March 2006 to April 2007. By   simple randomization, 90 patients (30 for LAVH and 60 for TAH) were selected. Demographic details and intra-operative and post-operative complications were recorded by the staff and were compared between the two groups.   Results: On average, LAVH operations took significantly longer than TAH operations   (100.17 ± 39.35 minutes 145.83 ± 41.55 minutes P< 0.0001). The total length of   hospital stay was significantly shorter after LAVH than after TAH (3.43 ± 0.90 days   3.94 ± 1.02 P= 0.025). Although the hemoglobin (gr/dl) drop in LAVH was significantly   higher than TAH (1.22 ± 0.94 and 0.58 ± 0.82, P=0.0012), blood transfusions were more   common in TAH (1 case versus 3 cases). The drug requirement to control pain during   hospitalization after the two surgeries was not significantly different between the two   groups. Fever was observed more often in the TAH group (P = 0.051). Finally, Intra-operative and post-operative complications were lower in LAVH than TAH.   Conclusion: Although operation length is significantly higher in LAVH, this procedure   is safer and more comfortable for patients and health care providers.   blood transfusion hemoglobin intraoperative complications laparoscopic assisted vaginal hysterectomy postoperative LAVH total abdominal hysterectomy TAH. 2008 5 01 22 28 http://mjiri.iums.ac.ir/article-1-62-en.pdf

Mona Nematian Homayoon Hadizadeh   Abstract   Backround: The first episode of an afebrile seizure is a common cause of admission   of children to emergency departments. Alot of tests are routinely performed for these patients. The cost of such an evaluation is high and benefits are doubtful. We conducted   this study in order to evaluate the results of the tests and find out what tests are necessary for children with first unprovoked seizure.   Methods: In a 7-year retrospective study files of 150 children aged between 1 month   and 14 years admitted with first afebrile seizure to the pediatric ward of Rasool Akram   hospital were reviewed. Reports of the brain neuroimaging studies (Ct-scan & MRI) and   laboratory tests were extracted.   Results: 150 patients with a mean age of 53 ± 48 months qualified for inclusion in the   study. 143 (95%) of 150 children with first afebrile seizure were imaged. Ninety percent   (128/143) had normal neuroimaging. Emergent computed tomography as the initial   study was performed in 90% (128/143) and MRI in 10% (15/143 ). Sixty patients had   both MRI and CT-scans. Clinically significant neuroimaging abnormalities were reported   in only 9.7% (14/143). There was a significant relation (P<0.001) between focal   seizures and abnormal neuroimaging. Children under 24 months of age were also more   prone to have abnormal imaging (p<0.002). Laboratory tests including complete blood   count (CBC) and chemistry panel (Na, K, Ca, BUN, Cr) were performed for all. Only   two patients had low serum calcium level, later diagnosed as vitamin D resistant rickets.   Conclusions: The most important aspect of management of a child after a first   afebrile seizure is careful history taking and physical examination. Laboratory tests   should be requested in very limited situations. Emergent brain CT-scans are recommended for children with focal seizures, abnormal findings on physical examination, presence of any predisposing factors and those under 24 months of age.   unprovoked seizure focal seizure neuroimaging. 2008 5 01 17 21 http://mjiri.iums.ac.ir/article-1-61-en.pdf

The study was performed to evaluate the   diagnostic method and the success rate of endoscopically diagnosed and treated CSF   rhinorrhea, and also investigations such as leakage site and etiologic factor.   Methods: This retrospective CSF leakage management review of patients experiencing   CSF rhinorrhea made from 1999-2006 included data regarding leakage etiology,   preoperative assessment, intraoperative techniques and postoperative followup.   Result: Sixty-five patients were managed endoscopically. CSF rhinorrhea etiology   was traumatic in 30 cases, iatrogenic in 23 and spontaneous in 12. We used nasal   endoscopy and high resolution computed tomography (HRCT) in all 65 cases while   CT metrizamide cisternography was used in 5 specifically and magnetic resonance   imaging for 5 others. Intrathecal fluorescein was used for intraoperative assessment   without complications, and only one case of meningismus was noted.   Conclusion: Several imaging methods were effective in diagnosing CSF leakage   sites. Endoscopic management and autografts were successful in repairing anterior   skull defects in 90.76% of the cases.

Recently, palmaris longus has been introduced   as an independent risk factor for the development of carpal tunnel syndrome. The   purpose of this study was to assess the association of carpal tunnel syndrome with   the presence of palmaris longus tendon and functional superficial flexor of the fifth   finger.   Methods: Fifty-four patients with severe and bilateral carpal tunnel syndromes   that had indications for carpal tunnel release, and underwent surgery, were enrolled   prospectively in this study. Seventy patients as control group were selected on a basis   of age, gender, occupation, diabetes mellitus, thyroid disease, and rheumatoid   arthritis. The presence or absence of the palmaris longus tendon and functional superficial flexor tendon to the little finger were assessed in both groups clinically.   Results: The prevalence of palmaris longus agenesis was significantly lower in   the carpal tunnel group but there was no association between carpal tunnel syndrome   and presence of functional superficial flexor to the little finger.   Conclusion: The presence of the palmaris longus tendon is associated with the   development of carpal tunnel syndrome.   carpal tunnel syndrome palmaris longus risk factor 2008 5 01 8 11 http://mjiri.iums.ac.ir/article-1-59-en.pdf

The aim of this study  was to evaluate the technique of osteoarticular allograft reconstruction of the distal radius after wide excision of a giant-cell tumor.  Methods: We analyzed 15 patients retrospectively who had reconstruction of the  distal aspect of the radius with use of an osteoarticular allograft, between 1981 and   2005 after excision of a giant-cell tumor with a minimum follow-up of 2 years (range:   26–125 months, median: 45 months).  Results: 15 consecutive patients with a Campanacci grade 3 giant-cell tumor of the  distal radius formed the study population. Three patients had a local recurrence at 8, 14  and 18 months. Non-:::union::: of the osteotomy line was diagnosed 6 months after surgery  in one case and needed bone grafting. Distal radio–ulnar joint instability was observed  in nine cases. Subchondral bone alterations and joint narrowing were present in all cases but were painful in only one patient. Five patients needed a revision of the osteoarticular allograft, at an average of 5.4 years (range: 0.8 to 12 years) after the initial reconstruction. The reason for the revision was a fracture of the allograft in four patients and recurrence of the tumor in one. Of the fifteen patients in whom the osteoarticular allograft survived, five patients reported no functional limitation, eight had limitation in  the ability to perform strenuous activities, and two had limitation in the ability to perform  moderate activities. The average range of motion of the wrist was 35 degrees of  dorsiflexion, 30 degrees of volar flexion, 10 degrees of radial deviation, 14 degrees of  ulnar deviation, 55 degrees of supination, and 70 degrees of pronation.  Conclusion: Reconstruction of the distal aspect of the radius with use of an osteoarticular allograft was associated with a low rate of recurrence of the tumor, a moderately high rate of revision, and little pain in association with common activities, good function, and a moderate range of motion.  distal radius giant-cell tumor osteoarticular allograft 2008 5 01 1 7 http://mjiri.iums.ac.ir/article-1-58-en.pdf
