Among secondary malignancies, acute myeloid leukemia(AML) is the most common and life-threatening neoplasm. Secondary acute lymphoblastic leukemia(ALL) is rare and only 10% of SMN is ALL. Patients with Wilm’s tumor are not protected from the secondary cancers after the primary diagnosis. Among patients with this tumor the most common SMN is AML and ALL is very rare. In this paper, we report a case of ALL, four years after diagnosis of Wilm’s tumor. The patient died nineteen months after the beginning of leukemia treatment due to multiple relapse and resistance to treatment. With advances in the treatment of childhood cancer, more children are surviving long periods of time therefore, careful follow-up and other examination sequels are necessary for early diagnosis of SMN.}, Keywords = {Key Words: 1) Secondary Malignancy 2) Secondary Leukemia }, volume = {11}, Number = {44}, pages = {889-894}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-86-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-86-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2005} } @article{ author = {Amini, A and Mortazavi, A and Nojoomi, M}, title = {Assessment of Early Oral Feeding on Gastrointestinal Symptoms after Cesarean Delivery and Total Abdominal Hysterectomy}, abstract ={Traditionally, surgeons believe that patients should receive a physician-dieted regimen for gradual expansion of their diets following major gynecologic surgeries including cesarean section and hysterectomy. Nowadays, based on clinical trials, this belife is under serious questions. Some studies have specially shown that early oral feeding is safe and additionally reduces cost and hospital stay in gastrointestinal and colorectal surgeries. However, there is upset about the probable ileus after early oral feeding. The objective of the present study was to compare gastrointestinal symptoms and tolerance to early oral feeding after cesarean section and hysterectomy. By a randomized controlled trial, 122 women under cesarean section and/or hysterectomy were studied in gynecology department of Firoozgar Hospital during 7 months. They were randomly allocated to two groups of early(60 subject), and late(62 subject) oral feeding. Subjects in early oral feeding group, received clear liquid diet within 6 hours of delivery or operation. Once 500cc was tolerated, a regular diet was given. The same protocol during 12 to 24 hours after surgery was given to late group. Exclusion criteria were: history of malignancy, bowel obstruction or inflammatory bowel disease and current or previous surgeries with extensive lysis or adhesion of the bowel. Patients were evaluated on a daily basis for bowel sounds, flatus, bowel movement, hunger, nausea, and vomiting. Two groups were compared in terms of hospital stay, nausea and vomiting and post surgery complications. T-test, chi-square, and Fisher’s exact tests were used for analyzing data. The demographic characteristics of two groups were similar statistically. There was not any significant difference between groups with regard to hospital stay, and mild ileus incidence. There was more nausea and vomiting proportion in early oral feeding group than that of late group (40% versus 19%). On average, regular regimen is tolerated 4 hours earlier in early oral feeding group than late group (20.9 versus 24 hour), and this difference was statistically significant. Early oral feeding group were earlier in first bowel movement, first post operation flatus and defecation, although these differences were not statistically significant. In conclusion, early oral feeding after cesarean delivery and abdominal hysterectomy is tolerated earlier with a more rapid return to a normal diet and bowel habit.}, Keywords = {Key Words: 1) Early Feeding 2) Cesarean 3) Hysterectomy 4) Ileus}, volume = {11}, Number = {44}, pages = {895-900}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-87-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-87-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2005} } @article{ author = {Otukesh, H and Moosavi, A and Hosseini, R and Goodarzi, R and Roozbahani, M}, title = {The Evaluation of Hearing Loss and Audiometric Disorders in Patients with Chronic Renal Failure, Chronic Hemodialysis and Transplantation Referred to Ali Asghar Pediatric Hospital from 2002 to 2003}, abstract ={Hearing loss is an important complication in chronic renal failure. The etiology of hearing loss is various in these patients, but uremia is the most important cause(uremic neuropathy). Other etiologies include electrolyte disorders (hyperkalemia-hyponatremia), vascular disorders, susceptibility to infections, antibiotics (e.g. aminoglycosides) and antihypertensive drugs. Studies on the effects of renal replacement therapy on hearing disorders are various and occasionally contradictory. Most studies have demonstrated that hemodialysis reduces uremia, but it is an ineffective or even intensifying treatment for hearing loss. On the contrary, renal transplantation is more remarkable in treatment of hearing disorders especially in early phase in most assessments However, it was also seen that hearing loss rebounds in later phases ( as much as previous degree or even more). Although hearing is an important sense in pediatric group, a few number of studies have been conducted on it in this group and the assessments in adults have also had various results. Therefore, it was decided to assess and compare hearing loss and its treatment in children with chronic renal failure undergoing dialysis or transplantation in order to be able to recognize the proper treatment for hearing loss in these children. 35 patients with chronic renal failure and hearing disorder who were treated by conservative hemodialysis or transplantation were assessed from 2002 to 2003 in Ali Asghar Hospital. Audiometry was performed in low, moderate and high frequency by an experienced person. The mean age was 12 years old. 20% of patients were treated by conservative therapy, 34% by hemodialysis and 46% of patients by transplantation.

It can simply be associated with fever without a focus for infection or can be the presenting sign of localized infections, including central nervous system infections. It is difficult to exclude meningitis merely on the basis of physical findings in children with febrile seizure under the age of 18 months. So, performing a lumbar puncture(LP) is a valuable diagnostic procedure in this group. However, despite many clinical studies in this regard, there is still controversy over doing LP. This cross-sectional retrospective study was undertaken to evaluate files of 245 patients with febrile seizure who were between 5 months and 6 years of age and were admitted to the pediatric ward of Hazrat Rasoul Hospital over a period of 5 years(1997-2002). The objective was to study children with febrile seizure to determine the necessity of performing LP in this group. Of 254 patients with mean age of 28.5±18.3 months, 206(84%) had simple febrile seizures, while 39(16%) presented with complex febrile seizure. Analysis of CSF in 9(3.6%) patients were compatible with meningitis. 4 out of 9 patients had bacterial meningitis. Mean age of children with meningitis was 13±4 months. All children with febrile seizure and underlying meningitis were under the age of 18 months and this was their first episode of febrile seizure and none of them had clinical signs of meningitis. In those with meningitis 56.6% had complex febrile seizure. 3(75%) children with bacterial meningitis and 2(40%) of those with aseptic meningitis had complex febrile seizures. Chi2 test results showed a significant relation(Pvalue<0.05) either between type of seizure and incidence of meningitis or type of seizure and incidence of bacterial meningitis. According to this study, meningitis was not a common finding in children with febrile seizure. However, we recommend performing LP in all children with febrile seizure under the age of 18 months.

M), 2) Medication treatment alone (clomipramine or Fluoxetine), 3) Cognitive-behavioral therapy in addition to medication treatment (CBT, add. M). The subjects’ religious affiliation was determined by religious attitude questionnaire. All patients were evaluated before the commencement of treatment and, once again, eight weeks after the treatment by Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Yale-Brown Obsessive-Compulsive Scales, a checklist of obsessive behaviors, religious beliefs questionnaire and dysfunctional attitude questionnaire. The results were analyzed and further interpreted by chi-squared test(X2) and one-way analysis of variance (ANOVA). The results showed that both cognitive-behavioral religious-cultural therapy in addition to medication treatment and cognitive-behavioral therapy in addition to medication treatment were effective in reducing the severity of anxiety symptoms, depression, obsession, and dysfunctional beliefs and attitudes. Medication treatment alone was only effective in reducing symptoms of depression and obsession, while it was not effective in reducing anxiety or dysfunctional beliefs and attitudes. Cognitive-behavioral religious-cultural therapy in addition to medication treatment was more effective than medication treatment alone, but in comparison with cognitive-behavioral therapy in addition to medication treatment was less effective. Based on the statistical analysis of findings, the addition of religious cultural components to cognitive-behavioral therapy was not necessarily effective in improvement of religious patients with symptoms of obsessive- compulsive disorder however, the raw scores of improvement indices were higher in subjects receiving cognitive–behavioral religious-cultural therapy in addition to medication treatment than the other groups.}, Keywords = {Key Words: 1) Anxiety Disorder 2) Obsessive-Compulsive Disorder }, volume = {11}, Number = {44}, pages = {913-923}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-90-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-90-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2005} } @article{ author = {Tamizifar, M and Sharafi, A.A and Yasrebi, B and Salehpour, Z}, title = {The Effect of Low - Intensity Ultrasound on Bone Growth in the Interior of Titanium Implants}, abstract ={The effect of ultrasound waves with low intensity on reducing the time of repair and healing of bone fracture has been known.

Therefore, a retrospective study was carried out for the first time in Firoozgar Hospital for a period of one year (2002) to study the ordering strategies in this hospital. Blood ordering and transfusion practices were evaluated in 364 elective surgical patients including 6 common major procedures: cesarean section (C/S), thyroidectomy, total hysterectomy, laminectomy, cholecystectomy and modified radical mastectomy (MRM) with the help of different indices such as cross-match to transfusion ratio (C/T ratio), transfusion probability (T%) and transfusion index (TI). Transfusion guidelines for these 6 procedures were proposed. Due to existence of a high total C/T ratio (21.5) (accepted standard value=2.5 times) and very low utilisation percenage of cross-matched units (only 4.7%), it is concluded that change of blood ordering pattern in this hospital is necessary.

Positive predictive values(PPV) were almost 50% for each well, moderately and moderately-poor differentiated groups, but 72.8% for poorly differentiated tumors. Kappa value was used for the evaluation of interobserver reproducibility and there was relatively good overall agreement(kappa: 0.371, Pv=0.000). A high gleason score on needle biopsy usually indicates a poorly differentiated tumor on RP specimens however, well differentiated tumors on needle biopsy does not correlate with final pathology grade in the majority of cases.}, Keywords = {Key Words: 1) Gleason Score 2) Biopsy 3) Prostate }, volume = {11}, Number = {44}, pages = {993-998}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-101-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-101-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2005} } @article{ author = {Alipour, P and Saedi, D and SadighiNejad, M}, title = {Angiographic Findings in Patients with Ruptured Cerebral Aneurysm}, abstract ={Cerebral aneurysms are of clinical importance regarding their fetal outcomes.

McMurray test, joint line tenderness and Latchman test were performed and then diagnostic arthroscopy was done. Diagnostic value of each method was compared. Clinical results of joint line tenderness and McMurray test were positive only in 58% of the patients with concurrent ACL and meniscus injury. However, in pure meniscus injuries, joint line tenderness was positive in all of the cases. Isolated ACL injuries(29%) and concurrent ACL with medial meniscus injuries(29%) were the most common injuries in arthroscopic findings. Bucket handle tearing was the most common type of meniscus injuries and Latchman test was positive in 90% of the cases with ACL injuries.

Recent articles have noted the protective role of HP in the incidence of esophagitis in patients with gastritis. The goal of the present research was to assess the relationship between HP and esophagitis incidence in patients with gastritis. This cross-sectional study was undertaken on 92 patients with gastritis who had referred for endoscopy to Firoozgar Hospital between 2002 & 2003. Urease test and endoscopy were used for diagnosis. Of 92 patients, 56(60.9%) and 36(39.1%) cases were with and without esophagitis respectively. Esophagitis frequency had significant difference in different kinds of gastritis with (Pvalue=0.003). There was not any significant difference between esophagitis frequency in patients with and without HP infection. In patients with esophagitis the HP frequency in non-infected patients was more than HP infected patients and in patients without esophagitis the HP frequency of infected patients was more than non-infected patients with HP. Based on the obtained results, esophagitis was more in cases with gastritis B. There was not any significant difference for HP infection between patients with and without gastritis and, therefore, it is concluded that there is not any relationship between HP infection and esophagitis in patients with gastritis.}, Keywords = {Key Words: 1) Gastritis 2) Helicobacter Pylori 3) Esophagitis}, volume = {11}, Number = {44}, pages = {1011-1018}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-104-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-104-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2005} } @article{ author = {Kashanian, M and Kamalian, N and Afsharpad, K}, title = {Frequency and Age Distribution of Ovarian Tumors in Shariati Hospital over a 20-year Period}, abstract ={The objective of the present study was to evaluate the frequency of ovarian tumors over a 20-year period and the age distribution of these tumors. A retrospective study was performed on ovarian tumors which were diagnosed in Shariati Hospital between 1976-1995, and had pathologic report. Frequency and age distribution of tumors were then evaluated. Of 493 evaluated ovarian neoplasia, surface epithelial tumors seen in 283 cases (57.4%) were the most frequent tumors. After that there were germ cell tumors in 152 cases (30.83%) and then sex-cord stromal tumors in 31 cases (6.28%). Metastatic tumors were in 24 cases (4.86%) and the 3 remaining cases were 2 cases of luteoma and 1 case of chondroma. The most frequent benign neoplasia of ovary was dermoid cyst (mature cystic tratoma) (39.53%) and after that scrocystadenoma (29.24%) and mucinous cyst adenoma (14.82%). The most frequent malignant neoplasia of ovary was malignant scrous tumors (53.69%) and after that there were metastatic tumors (16.1%) and mucinous cyst adenocarcinoma (14.09%). The greatest number of patients (111 cases) were in 21-30 age group and after that 99 patients were in 51-60 age group and 96 patients were 31-40 years old. In our study, surface epithelial tumors were less than the other world statistics and germ cell tumors were more than other studies which was probably due to younger age of our patients (the most frequent number of patients were in 21-30 age group). Metastatic tumors were more frequent in this study and it is probably because of late diagnosis of malignancies. In sex-cord stromal tumors the most frequent number of tumors was fibrothecoma in this study, whereas in the other studies, the most prevalent sex-cord stromal tumor is granulosa-theca cell tumors.

The aim of the present study was to characterize the changes of CRP, ESR and WBC after elective orthopedic surgery. In 94 patients who underwent elective orthopedic surgery and had normal values of inflammatory factors such as ESR, WBC and CRP serial measurements of CRP, ESR and WBC were done before and 1, 3, 5, 7, 14, 28 and 59 days after surgery from December 2002 to February 2003. The results indicated a maximal count of WBC on the first day after surgery, maximal CRP values on the third day and maximal ESR rates on the fifth day after surgery. Changes of WBC were irregular, but ESR and CRP, after achieving maximal values on mentioned days, became respectively normal after 28 and 14 days following post-operation. Age and sex did not influence the pattern of changes but extensive surgeries were accompanied with higher values of ESR and CRP. Pattern of changes in CRP and ESR values are so typical that any deviation from this pattern can indicate occurance of complications such as infection.

The goal of the present study was to determine the preference of one of volatile or intravenous anesthetic methods in patients in sitting position in terms of adequacy of perfusion to vital organs. We studied combination of two different factors: sitting position and anesthesia regimen in 38 patients undergoing the same type of surgical operation on shoulder(rotator cuff repair). Patients were anesthetized in two different methods after similar induction of anesthesia, and then they were randomly assigned into volatile(Halothane) and intravenous(Propofol) groups.

Common and sometimes life-threatening complications of these drugs have always been important among athletes. The use of these drugs was common among athletes in 1950s, and since then, there has been some reports from all over the world about their complications. Liver tumors, gynecomastia, short stature in adolescents and hair loss in athletes are some of the most common complications. Due to some reports about anabolic steroids abuse in athletes in our country, this study was undertaken to determine the frequency of using anabolic steroids and athletes awareness of them. In this cross-sectional study, 403 bodybuilding athletes from 9 clubs in Karaj were studied through a multistage random sampling method. Method of collecting data was a questionnaire with 25 demographic and specific questions about athletes’ awareness of anabolic steroids complications. SPSS software (ver 11), chi-squared test, t-test, correlation and ANOVA were used for data analysis. Athletes’ mean age was 22.6(±8) and most of them had education under diploma(47.1%). Proportion of the current use of anabolic steroids among athletes was 13% and former use of these drugs was reported in 13% of the athletes. Oxymetholone was the most common anabolic steroids among athletes(16.7%) and 22.2% of them used injectable drugs. The total score of the questionnaire was 400, out of which the mean score of athletes’ awareness was 66.8. The highest score belonged to Nandrolone complications. There was a significant positive correlation between athletes’ awareness of anabolic steroids and their age, level of education and their experiences. On the whole, the history of at least single use of anabolic steroids in athletes’ was 26% which is a high and worrying proportion. Athletes’ awareness of drug complications was very low therefore, making them aware of these complications and conducting researches on young people’s attitude towards these drugs is recommended.}, Keywords = {Key Words: 1) Anabolic Steroids 2) Athletes 3) Awareness}, volume = {11}, Number = {44}, pages = {1057-1063}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-110-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-110-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2005} }
