Abstract
Sixty-nine children with phenylketonuria (PKU) under coverage of Tehran Genetic Research and
Consultation Center, fed Lofenalac and Phenylfree were studied. The 24-hour dietary recall method was used
to determine food intake and blood samples were analyzed for iron parameters. The results showed that over
7% of the children had a low intake of energy, protein and iron. In addition, hemoglobin and hematocrit were
lower than normal in 3.1% of the children, while in 24.2% of them there was decreased serum transferrin
saturation percent. There was a statistically significant relationship between lenght of diet therapy and iron
parameters. The findings show that inadequate nutrient intakes may, over time, cause appearance of anemia signs in the children with PKU dependent on special formulations

Abstract
Introduction: The regulation of neuroendocrine axis is one of the most important goals in the treatment of Rheumatoid Arthritis. Disease modifying drugs such as chloroquine with low dose steroid is the first choice in clinical practice by some physicians. This combination therapy is evaluated by this study. Methods: This survey is a prospective study on furty patients. Variables for determining the activity index of disease were joint tenderness, joint swelling, morning stiffness and erythrocytes sedimentation rate in two years follow up. Results: Decrementation of disease activity index was statistically significant before and after treatment, joint tenderness (X²=7.205, P=0.007), morning stiffness (X²=19.253, P=0.00001), joint swelling (X²=14.107, P=0.0001), ESR (T=2.428, P=0.02). Conclusion: The combination of chloroquine with low dose steroid is beneficial in the treatment of Rheumatoid arthritis

Abstract
We studied fertility indices of Iranian and non-Iranian populations which were covered by 23 Rays health houses. This cross-sectional study aimed to prove the effect of increasing number of non-Iranian immigrants on health indices of the area covered by Tehran university of medical sciences and health services, consequently giving attention to specific health programs. The data collection method was census of permanent residents of the villages by means of vital horoscopes. 8494 of 27611 persons were non-Iranian. Dependency ratio and natural growth rate was 75%, 1.14% in Iranians and 98%, 1.74% in non-Iranians, respectively. Mortality in non-Iranians was 1.24 times more than Iranians. General fertility rate in Iranians was 60 and in non-Iranians was 110 live births in 1000 women of child bearing age. Total fertility rate in Iranians was 1.73 and in non-Iranians 3.27 neonates for each woman. Age-specific fertility rates were absolutely higher in non-Iranians. Gross eproductive rate was 0.87 in Iranians and 1.59 in non-Iranians. Mean number of girls born by a non-Iranian mother will be double times of an Iranian mother (P<0.01). Modern contraceptive methods coverage was 70% in Iranian couples and less than 40% in non-Iranian couples. 96.94% of Iranian deliveries and 70.9% of non-Iranian deliveries were safe (P<0.01).

Abstract
Metabolic alkalosis is characterized by high HCO3- as it is seen in chronic respiratory acidosis, but PH differentiates the two disorders. There is no characteristic symptom or sign. Orthostatic hypotension may be encountered. Weakness and hyporeflexia occur if serum K+ is markerdly low. Tetany and neuromuscular irritability occur rarely. We report the results of retrospective data analysis of metabolic alkalosis in 15463 patients hospitalized Pediatric Medical Center in Tehran during years 1995-1997. We found 50 cases of metabolic alkalosis (rate of 0.32 percent. 64 precent male and 36 percent female). Most of them had growth failure (40% were bellow 3 percentile of height by age, 44% bellow 5 percentile of weight by height). More than 60 percent had hypokalemia, hypocloremia and hyponatremia. The most common cause of Metabolic alkalosis was cystic fibrosis and pyloric stenosis. Fifty percent of cystic fibrosis patients and Bartter cases had metabolic alkalosis. Metabolic alkalosis should be considered in every pediatric patient presented with projectile vomitting.

Abstract
Background: Umbilical cord blood gas analysis is a useful method for assessment of oxygenation and acid-base status in neonates. Severe fetal acidemia is associated with increased perinatal mortality and increased risk of subsequent impaired neurological development. Due to high percentage of C/S in our country and the effect of anesthetic medications on umbilical blood gases which can cause neonatal acidosis and hypoxemia, the study of umbilical cord blood gas in vaginal delivery versus cesarean section is mandatory.
Methods: In this cross-sectional study one hundred samples were taken from Mostafa Khomeini hospital in summer 2004. The samples were taken immediately of umbilical vein after clamping the umbilical cord and analyzed after 10 minutes. Cases were classified in to 3 groups: vaginal delivery (n=40), elective C/S under general anesthesia (n=35) and C/S under spinal anesthesia (n=25). Duration of anesthesia and its effect on blood gas and infants apgar were assessed.
Results: In the first group (vaginal delivery) mean blood gase parameters were pH=7.3064.73, pO2=25.246.87, HCO3=20.562.03, Apgar=8.820.38 and pCO2=41.826.57. In the second group (general anesthesia) mean blood gaze parameters were: pH=7.3044.73, pO2=38.7014.02, pCO2=43.265.87, HCO3=21.1113 and apgar score=8.170.7. In the third group (spinal anesthesia) mean blood gaze parameters were: pH=7.3014.50, pCO2=44.14.99, HCO3=21.382.15, pO2=26.625.5 and apgar=8.600.62. The apgar scores and pO2 demonstrated significant relationship with type of anesthesia. The apgar score was lower and pO2 was higher in C/S under general anesthesia compared with the other two groups. There was significant relationship between duration of anesthesia and umbilical pO With increasing duration of anesthesia, pO2 was reduced. Between the type of delivery and anesthesia duration with PH, pO2, pCO2 and HCO3 were not meaningful relationship (P<0.05).
Conclusion: There was no significant difference between type of delivery and umbilical blood gas parameters. Neonatal apgar score in NVD is higher than the other groups. With increasing duration of general anesthesia in C/S, umbilical po2 is reduced.

Abstract
Background: Rheumatoid arthritis (RA) is an autoimmune disorder with unknown etiology. In recent years, a great number of studies have investigated the possible role of reactive oxygen species in the etiology and pathogenesis of Rheumatoid Arthritis. The aim of this study was to analyze the level of activities of catalase, glutathione peroxidas (GSH-Px), Super oxide dismotase (SOD) in patients with RA compared with the healthy subjects.
Methods: In a case-control study sixty rheumatoid arthritis patients 18-75 years old and 60 healthy sex and age-matched controls were selected, Catalase activity was measured by determining the constant rate (k) of hydrogen peroxide decomposition. GSH-Px activity of plasma was measured with spectrophotometer by Glutathione oxide generation due to GSH-Px. SOD activity is measured by degree of inhibition effect of SOD in generating super oxide radicals by xanthine and xanthine oxidase. C-reactive protein and rheumatoid factor values were determined by agglutination and latex tests.
Results: The plasma activity of catalase (p<0.001), GSH-Px (p<0.01), plasma level of hemoglobin and hematocrit (p<0.05) were significantly lower in patients with RA comparing with controls. The reduction in SOD activity was not significant (p>0.05). There was a negative significant relation between C reactive protein and Rheumatoid factor values with the erythrocyte activity of catalase and GSH-Px (p<0.01).
Conclusion: These results suggested that oxidative stress plays a very important role in the inflammation and pathogenesis of RA.

Abstract
Background: Abdominal compartment syndrome (ACS) is a clinical entity that develops from progressive, acute increases in intra-abdominal pressure (IAP) and adversely affects all vital organ systems In this study, the development of intra-abdominal hypertension (IAH) and ACS in a surgical ICU population is described and examined.
Methods: Over a one-year period (2004), urinary bladder pressure (UBP) was measured prospectively in all surgical patients with abdominal problems admitted to the ICU of the Imam Hospital complex. UBP of >20 cm H2O indicated IAH. ACS was defined as the development of multiple organ dysfunction including peak airway pressure (PAP) >50 cm H2O, Horowitz quotient <150 torr or urine output <0.5 ml/kg/hr in the setting of IAH. Data were gathered on all patients with IAH and ACS.
Results: We evaluated some 353 patients, consisting of 165 elective laparatomies and 188 emergency cases, including 28 trauma patients. The incidence of IAH and ACS was 2 and 1 per cent (7 and 3 patients, respectively). The mean IAP of these seven patients was 29.8 cm H2O. No elevated IAP was observed after elective laparotomy (165 patients), nor in emergency cases with temporary abdominal wall closure (29 patients). APACHE II score, PAP and worst base deficit were significantly higher in patients with elevated IAP. None of the three patients with ACS underwent decompressive laparotomy. The mortality rate for patients with elevated IAP was 85%, significantly higher than the total study population.
Conclusion: IAH is a rare disease of the rarity of IAH, routine measurement of IAP is necessary only in high-risk patients. Prophylactic temporary abdominal wall closure may prevent IAH and ACS in high-risk patients. Patients with elevated IAP have dismal outcomes. Critical care practitioners should become familiar with different aspects of IAH and ACS, including decompressive laparotomy.

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: The incidence of riboflavin deficiency is high in women and children in developing countries and the deficiency almost invariably occurs in combination with deficiencies of other water soluble vitamins. The objective of this study was the assessment of riboflavin status of rural school children in Kerman province and its relationship with riboflavin, protein and energy intake.
Methods: In this cross-sectional study, 327 primary school children were randomly selected by the stratified multistage cluster sampling method. Variables for classifications were sex and socio-economic status (according to the educational level). This study was conducted by the Department of Nutrition and Biochemistry of School of Public Health in Tehran University in the winter of 2001. A twenty-four hour recall questionnaire was completed by and 5 cc of venous blood was taken from each student. Riboflavin status was assessed by measuring the glutathione reductase activity coefficient (EGR – AC) of the red blood cells. Chi-Square and Pearson’s correlation coefficient tests were used to determine correlations. Student’s t–test was used to show the differences in the mean of EGR – AC between the classifications of independent factors.
Results: The relationship between riboflavin status and its independent variables including the status of riboflavin, protein and calorie intake were assessed. Outputs of the study indicated that 39.7% of the boys and 43.6% of the girls (41.8% together) were marginally riboflavin deficient. Furthermore, 37.7% of the boys, 33.4% of the girls (35.4% together) were frankly riboflavin deficient. An average of 67.2% of the children (70.1% boys, 63.7% girls) had enough intake of riboflavin, and 76.2% of the children (79.9%, boys, 72.5% girls) had adequate intake of protein. However, only 22% of the children (24.5% boys, 19.3% girls) had sufficient caloric intake. Outputs of this dietary evaluation reveal that there is a relationship between riboflavin status and protein intake status (P<0.05).
Conclusion: This study shows that riboflavin deficiency is an important problem for the rural school children of Kerman province and the level of protein intake is an important factor affecting riboflavin status in these children.

Abstract
Background: Acupuncture is one of the most effective methods of alleviating pain in different situations including chronic and acute pain management. The aim of this study was to evaluate the effectiveness of acupuncture in the reduction of post-operative pain after hernia repair.
Methods: In this placebo-controlled, double-blinded clinical trial, we enrolled 60 male patients aged 30 to 60 years old with an ASA physical status of I or II undergoing elective inguinal hernia repair under general anesthesia in Imam Khomeini Hospital, Tehran, Iran. All patients experienced standard anesthetic and surgical procedures. After completion of the operation and while the patients were still under general anesthesia, they were randomly assigned to two groups: acupuncture (with stimulation of GV2, GV4 and SP6 points with sterile acupuncture needles), and control (with sham acupuncture stimulation). After termination of anesthesia, during the first six hours, the pain intensity was evaluated hourly. Pethidine (25 mg) was administered for the patients when necessary. Pain intensity and pethidine use were recorded and compared between the two groups.
Results: The mean age of two groups did not differ. Pain intensity was significantly lower in the acupuncture group between the second and fifth postoperative hours. Moreover, pethidine use was significantly lower in the acupuncture group versus the control group during the first six hours after surgery (12.07±7.5 mg vs. 12.91±6.5 mg, respectively p=0.0001).
Conclusion: The application of acupuncture in patients is associated with a marked decrease in pain after inguinal hernia repair and does not have any serious complications. Acupuncture is strongly recommended for all post-operative patients.

Abstract
Background: Epithelioid sarcoma is a malignant soft tissue tumor of uncertain histogenesis, categorized as a morphologically distinct neoplasm that characteristically affects the distal parts of the extremities in young adults. In fact, epithelioid sarcoma is the most common soft tissue sarcoma in the hand and wrist.
Case report: This 32 year-old male presented with an inguinal swelling, for which he underwent surgery with the initial intent of inguinal hernia repair. With this uncommon manifestation and site, among the differential diagnosis were abscess and GI malignancies. However, after a supplementary evaluation that included biopsy of the ulcer margin, the diagnosis focused on undifferentiated high-grade epithelial tumor, highly suggestive of epithelioid sarcoma. Immunohistochemical studies revealed CD34 and cytokeratin positivity, which confirmed this diagnosis.
Conclusion: Due to the malignant nature, invasive behavior and high recurrence rate of this tumor, as well as its unknown response to chemotherapy and radiation, extensive resection and hepatectomy are recommended for treatment.

Background: Standard thoracotomy necessitates division of
thoracic large muscles leading to pain and impaired respiratory movements
muscle sparing postero-lateral thoracotomy has been suggested as an alternative
to reduce the aforementioned effect. The aim of this study was to compare
muscle saving posterolateral thoracotomy with standard thoracotomy.
Methods: This study was a clinical
trial. All patients who were candidates for elective thoracotomy were included
and divided into two groups of muscle saving thoracotomy and standard
thoracotomy randomly. Required time for opening and closing the chest, amount
of prescribed narcotics, shoulder movements (flexion, extension, abduction and
internal rotation), pulmonary function (FVC, FEV1, VC), development of seroma, and
duration of hospitalization were assessed. Shoulder movements and pulmonary
function were measured immediately before operation and 7 days later while pain
measured in 1st and 7th post-operative days.
Results: 60 patients (42 males) entered the study and
there were no significant differences regarding age and sex distribution
between two groups (p>0.05). Mean
duration of opening the chest in muscle saving thoracotomy was significantly
longer than standard procedure while the duration of closing the chest wall was
significantly shorter in muscle saving thoracotomy (p<0.05). FVC and range of motion of the
shoulder were higher and post-operative pain was lesser in muscle saving
thoraocotomy than standard thoracotomy (p<0.05). There were no significant differences regarding
prescribed narcotics and duration of hospital stay (p>0.05). Seroma developed in 13% (n=4) of muscle saving group.
Conclusion: Muscle saving thoracotomy can be used as an
appropriate alternative for standard postero-lateral thoracotomy in elective
thoracic operations.

Background: Coronary artery anomalies
may be seen in 1-5% of coronary angiographies. Origin of the left
coronary artery from right aortic cusp is a very rare anomaly and its incidence
is about 0.15%. This
anomaly could be presented by myocardial ischemia and even sudden cardiac death
during exercise in young patients. For the diagnosis of coronary anomalies
different diagnostic modalities such as, echocardiography, angiography and CT angiography
can be helpful.
Cases: We
report 3 cases with this anomaly and two of them did
not have any lesion in their coronary arteries One of these patients had severe
coronary artery disease and underwent coronary artery bypass graft surgery.
Conclusion: Although abnormal origin of
left coronary artery from right aortic valsalva sinus is a rare anomaly, due to
causing ischemic cardiac symptoms and the possibility of sudden cardiac death it
is considered an important anomaly. For definite diagnosis of this anomaly
coronary angiography and/or CT
angiography is useful.

Background: Appendicitis is more common during the second
and third decade of life and appendectomy scar is important in terms of
cosmetic issues. The scar is an important factor in the patient's satisfaction.
Conventional teaching has an emphasis on the closure of skin incision with
"separate" sutures. The aim of this study was to reconsider this dogma.
Methods: Among 321 patients with acute
appendicitis who came to the emergency unit of Imam Khomeini Hospital in
Tehran, Iran since april 2007
till april 2008, 278 (86.6%) patients had
uncomplicated appendicitis and were enrolled in our clinical trial. The
patients were randomly assigned to two groups of interrupted suture closure (n=139) and subcuticular
suture closure (n=139). Anesthesia method and
surgical technique were similar between the two groups. All patients were
followed up post-operatively (four weeks) for the presence of infectious
drainage, pain, erythema, swelling and warmness at the surgical site.
Results: The patients' sex and
their mean age were not statistically different between the groups. There was
no significant difference in the frequency of surgical site complications between
the two groups (five cases in the "interrupted" group and eight cases in the
"subcuticular" group p=0.415).
Conclusion: This study showed that
appendectomy incision closure with subcuticular sutures did not increase the
risk of wound complications. From the point of better cosmetic outcome of
subcuticular sutures, this method may be the method of choice for the closure
of appendectomy incisions in uncomplicated appendicitis.

Abstract
Background: Lung diseases and lung cancer are among the most dangerous diseases with high mortality in both men and women. Lung nodules are abnormal pulmonary masses and are among major lung symptoms. A Computer Aided Diagnosis (CAD) system may play an important role in accurate and early detection of lung nodules. This article presents a new CAD system for lung nodule detection from chest computed tomography (CT) images.
Methods: Twenty-five adult patients with lung nodules in their CT scan images presented to the National Research Institute of Tuberculosis and Lung Disease, Masih Daneshvari Hospital, Tehran, Iran in 2011-2012 were enrolled in the study. The patients were randomly assigned into two experimental (9 female, 6 male, mean age 43±5.63 yrs) and control (6 female, 4 male, mean age 39±4.91 yrs) groups. A fully-automatic method was developed for detecting lung nodules by employing medical image processing and analysis and statistical pattern recognition algorithms.
Results: Using segmentation methods, the lung parenchyma was extracted from 2-D CT images. Then, candidate regions were labeled in pseudo-color images. In the next step, some features of lung nodules were extracted. Finally, an artificial feed forward neural network was used for classification of nodules.
Conclusion: Considering the complexity and different shapes of lung nodules and large number of CT images to evaluate, finding lung nodules are difficult and time consuming for physicians and include human error. Experimental results showed the accuracy of the proposed method to be appropriate (P<0.05) for lung nodule detection.

Abstract
Clostridium difficile (C. difficile) is an important factor in the development of the gastrointestinal diseases because of irrational antibiotic prescription and antimicrobial resistance. In the past, this bacterium was introduced as an agent of the infection in the hospitals called "hospital acquired Clostridium difficile infection". This infection is a main cause of morbidity and mortality internationally. But changing in the epidemiology of the infection was observed in recent years. People not taking antibiotics as well as any contact with the clinical system were hospitalized due to the infection named "Community-Associated Clostridium difficile infection". Furthermore, the hypervirulent strains of C. difficile were identified outside of the health care facilities in different sources such as environment, animals and food products. Today the role of C. difficile has not been confirmed as a zoonotic agent or foodborne pathogen. Taking into account, it should be taken attention to the sensitive individuals such as pregnant women, elderly and children for the consumption of the contaminated food products with C. difficile spores and probable cause of the infection in these individuals. For this purpose, presentation of the guidelines or the prevention strategies for the transmission of bacteria in the society as well as the healthcare facilities is important. In this review study, the history, the risk factors of disease and the reports of infection in the healthcare facilities and outside of this environment in Iran were discussed. Finally, we supposed that based on the isolation of C. difficile with different genetic profile in Iran in comparison with international ribotypes, the existence of native strains leading to the infection in the community and the healthcare facilities is possible. This hypothesis shows the significance of regional differences in the epidemiology and microbiology of disease. In addition, according to the present reports on the irrational prescription of the antibiotics in our country, it seems that C. difficile infection is increasing but any continuous monitoring is not being occurred for the supervision in Iran. Approving these hypotheses need to the careful and continuous assessment besides comprehensive examination of molecular epidemiology of disease in the organizations related to the health in Iran.

Background: We retrospectively compared the clinical outcome of post-cardiac surgery tracheal extubation between patients extubated with a lower than normal pH and patients extubated according to our routine institutional protocol. Our main goal was to clarify that strict adherence to the current criteria is dispensable.
Methods: In this retrospective cohort study, we recruited 256 patients who met our study criteria and divided them into the exposed group (n= 95) and the control group (n= 161). The inclusion criteria consisted of coronary artery bypass grafting alone and age> 18 years. The exclusion criteria comprised the use of corticosteroids in the preceding 2 weeks, Serum creatinine (SCr)> 2 mg/dL, uncontrolled diabetes, liver dysfunction, Glasgow coma scale <13, and acetazolamide and sodium bicarbonate use. The arterial blood gas (ABG) characteristics before and 6 hours after extubation, extubation failure rate, length of stay in the in ICU, length of stay in the hospital and mortality were compared between the two groups.
Results: In the control group, the males outnumbered the females and the ejection fraction was higher relative to that in the exposure group (P= 0.01 and P= 0.02, respectively). There were more patients with chronic obstructive pulmonary disease in the exposure group (P< 0.005) and also the euroSCORE was higher (P< 0.002). There were no significant differences between the groups regarding the ABG values at the time of ICU admission. Significantly higher levels of FiO2 and PaCO2 (P< 0.001 for both) as well as lower HCO3 and pH (P< 0.001 for both) were observed in the exposure group immediately before extubation. Following extubation, there was a significant increase in pH and a significant reduction in FiO2 need in the exposure group (P< 0.001 for both). The extubation failure rate, length of stay in the in ICU, length of stay in the hospital, and mortality rate were not different between the 2 groups.
|
Conclusion: The patients with a lower than normal pH, tracheal extubated at the discretion of the ICU anesthesiologist did not have a clinical outcome worse than that of the patients extubated in accordance with our routine institutional protocol.

Background: The most common symptom of patients with gestational trophoblastic neoplasia is abnormal vaginal bleeding. Despite repeated visits of patients with postpartum choriocarcinoma and abnormal postpartum hemorrhage, delayed diagnosis leads to advanced disease with widespread metastasis. Therefore, occurrence of choriocarcinoma with variable patterns in different diagnosis of late onset postpartum hemorrhage should be considered. Early diagnosis of choriocarcinoma after term pregnancy is important that resulted in decrease of maternal morbidity. Therefor late onset postpartum hemorrhage should have an awareness. The aim of this study was to report a case of choriocarcinoma after caesarian section.
Case Presentation: A 33-years-old woman one month after antecedent caesarian section in her second pregnancy admitted with abnormal vaginal bleeding. Based on raised titer concentration of β-hCG was 187000 u, with clinical suspicious of choriocarcinoma she was referred to oncology department of Ghaem Hospital, Mashhad University of Medical Sciences, Iran, in 2016. Vaginal exam revealed an enlarged uterus about 10 weeks of pregnancy. Transvaginal sonography showed an intracavitary heterogeneous mass with irregular surface in fundus without myometrium invasion. Extra pelvic metastasis excluded via vaginal exam, pulmonary X-ray and, ultrasonography and computed tomography scan. Due to early stage of gestational trophoblastic neoplasia and diagnosis of this condition, single agent chemotherapy (methotrexate) was recommended, but because of unresponsive disease, subsequently, she was treated with combination chemotherapy (etoposide, methotrexate, and actinomycin, followed by cyclophosphamide and vincristine) that led to remarkable response. After three courses of therapy, normal level of β-hCG was observed and now the patient is free of disease and under-serial follow-up visit for choriocarcinoma.
Conclusion: Diagnosis of choriocarcinoma should be considered in any postpartum woman with abnormal vaginal bleeding.

Abstract
Background: Vaginal candidiasis is common in during pregnancy. It may lead to complications like abortions, premature birth, low birth weight, chorioamnionitis and fungal systemic neonatal infection. The aim of present study was identification of Candida species by mycological and molecular methods in pregnant women with vaginal candidiasis.
Methods: This cross-sectional study was performed on 80 pregnant women with or without clinical symptoms of vulvovaginal candidiasis referred to Shahid Noorani Talesh Hospital, Gilan University of Medical Sciences, Iran, from April to December 2015 (8 months). All specimens were examined by direct microscopy and culture on CHROMagar Candida medium for isolation and differentiation of major clinical-significant Candida species (spp.). Cultured media were incubated at 35 °C for 48 hours and evaluated based on color and number of grown colonies. If no growth was observed, the media were incubated for several additional days. Subcultures were done on Sabouraud dextrose agar (Merck, Germany) and Corn meal agar with Tween 80 media (Micromedia, Hungary) for further study. Identification of Candida spp. carried out by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.
Results: In this study, vulvovaginal candidiasis was observed in 20 (25%) patients. Twenty-two isolates were obtained from culture of specimens on CHROMagar Candida medium (Paris, France). The most common isolated species was Candida albicans 16 (72.8%) and followed by Candida glabrata 5 (22.7%), Candida tropicalis 3 (13.6%) and Candida krusei 1 (4.5%) cases. Two patients had mixed infection with 2 different Candida species (C. albicans and C. glabrata) While using PCR-RFLP method, the Candida species were identified as 13 (59.1%) Candida albicans, 5 (22.7%) Candida glabra, 3 (13.6%) Candida tropicalis and 1 (4.5%) Candida krusei cases, respectively. In direct examination were seen yeast budding cells and pseudohyphae in 8 culture positive specimens. In the present study, results of conventional mycological method in differentiation of Candida spp. were consistent with molecular results in 80% of cases. There was also significant correlation between vulvovaginal candidiasis with clinical symptoms (P<0.0001), including diabetes mellitus (P<0.014), and taking antibacterial drugs (P<0.003) in pregnant women.
Conclusion: PCR-RFLP was able to identify correctly the Candida spp. as a complementary method.

Abstract
Background: Renal artery stenosis (RAS) is a known cause of secondary hypertension and renal failure. The most patients with renal artery stenosis are asymptomatic. So, the exact prevalence of this disease is unknown. The gold standard of diagnosis of RAS is renal angiography that is an expensive somewhat hazardous procedure and may revealed nothing. The aim of this study was to develop a simple risk model score to predict significant RAS based on known risk factors. This may enable us to select patients with high probability of having RAS to perform angiography.
Methods: A total of 4177 patients whom underwent renal angiography from April 2001 to March 2016, were randomly assigned to a development and a validation dataset in ratio of 2:1 respectively. The clinical and laboratory data of patients were analyzed by multivariate regression analysis. The factors of female sex, history of hypertension and glomerular filtration rate were determined as predicting factors and they were assigned a weighted integer, the sum of the integers was a total risk score for each patient. This model was examined at validation set.
Results: We retrospectively evaluated all patients undergoing renal artery angiography since 15 years ago. We extracted all risk factors of RAS including age, sex, height, weight, and history of diabetes, hypertension and hyperlipidemia. We also looked at coronary or peripheral vascular diseases and presence of heart failure. The age of patients was 63.5±11.2 years and 40% of the patients were female. The significant RAS was defined as 70% or more narrowing of renal artery. The prevalence of renal artery stenosis was 14.4% and 13.5% in development and validation dataset respectively. The area under curve and confidence interval for final mode in development dataset was 67.9% (65.0-70.8%). The rates of RAS increased with increasing risk score. In 1402 patients in validation dataset the model showed good discrimination power (cstatistic= 0.76)
Conclusion: This model simply assesses the risk of RAS using available information. This model can be used both in clinical and research purposes. The power of model for diagnosis of RAS is estimated to be 72.6% (68.8%-76.4%).
