Background: Various imaging tests as well as different scoring systems based on symptoms, signs and laboratory findings are commonly used to improve diagnostic accuracy in acute appendicitis. The aim of this study was to compare the diagnostic accuracy of MANTRELS scoring system (designed by Alfredo Alvarado), which is based on symptoms, signs and laboratory results, with sonographic findings.
Methods: In this prospective observational study, 106 patients with acute abdomen suspicious of acute appendicitis at Sina Hospital, Isfahan, Iran, were studied from March 2004 to February 2006.
Results: The disease was most common in patients aged 20-29 years, with male predominance. All patients had appendectomies. One hundred patients had acute appendicitis and six had negative appendectomy. Among the patients with acute appendicitis, 88% had an Alvarado score of ≥6 and 12% had a score of ≤5. Among the six patients with negative appendectomy, 66.7% had Alvarado scores of ≤5 and 33.3% had scores of ≥6, which was significantly different (p=0.005). The sonographic results were abnormal in 71.9% of patients with acute appendicitis and in 25% of patients with negative appendectomy, which was not significantly different (p=0.08). In our study, the diagnostic accuracy of an Alvarado score ≥6 was 88% and that of the sonographic results was 71.9% for acute appendicitis. If the Alvarado score ≥6 and abnormal sonographic findings are considered together, the diagnostic accuracy improves to 97.2%.
Background: Trauma is a common problem in the world, predominately affecting young adults. Considering the high mortality rate in patients suffering from thoracic trauma, the condition is considered to be extremely important. The purpose of this study was to evaluate the prevalence and the epidemiology of chest trauma as well as the severity of the resulted injury in Tehran, Iran.
Methods: This prospective, descriptive study was conducted on patients admitted to three medical centers in Tehran during June 1997 and 1998 due to chest trauma. The data on the demographic information of the patients, the mechanism of the trauma and the severity of the injury were collected and analyzed.
Results: Three hundred forty two patients were admitted to hospital due to thoracic trauma the majority of which were male adults. Blunt trauma especially secondary to motor vehicle accidents were the most frequent cause of chest injury in the studied patients. In 280(82%) of the cases, another form of trauma was also reported. Chest wall injury was the most common type of thoracic trauma in these patients. The trauma was reported to be mild in 181(53%) of the patients (ISS<7). Only 42(12%) patients required surgical intervention. The overall mortality rate was 14% which was reported to be ISS- related.
Conclusion: Chest injury is quite prevalent among trauma patients and is associated with other injuries in a considerable number of the patients. This type of trauma is associated with a high mortality rate among elderly and therefore needs special attention and care.
Background: Previous studies have suggested the presence of a relationship between the increase of NRBC and the duration and intensity of asphyxia. The purpose of this study was to evaluate the relationship of fetal heart rate pattern and the number of NRBC's in umbilical cord blood sample at birth.
Methods: We enrolled 322 pregnant women with healthy, term fetuses who referred to Mirza Kouchak Khan Hospital for pregnancy termination in 2005 in a case-control study. All patients underwent continuous FHR monitoring and based on their FHR pattern, they were divided into two groups with normal FHR pattern and at least one abnormality in FHR pattern (including absence of beat to beat variability absence of proper acceleration and early, late, variable and prolonged deceleration). Samples of umbilical cord blood were evaluated for NRBC count and pH immediately after birth. The variables were compared in these two groups.
Results: The mean NRBC count was significantly higher in patients with any kind of deceleration (late, variable, early or prolonged) in comparison with controls (respectively 11.88±4.406, 8.32±4.64, 10.58±5.366, and 4.11±4.913 vs. 0.93±1.790 in controls). Furthermore the mean NRBC count was significantly higher in patients with absence of acceleration or beat to beat variability (10.73±5.07 and 13.73±3.58 vs. 1.47±2.50). There was a negative correlation between 5th minute Apgar score and umbilical cord blood sample with mean NRBC count of umbilical cord blood sample.
Conclusion: Any abnormality in FHR pattern is associated with a significant increase in mean NRBC count of umbilical cord blood sample. There is also a significant relationship between the 5th minute Apgar score and umbilical cord blood sample pH, and mean NRBC count in umbilical cord blood sample.

Background: Knee
arthrosis is one of the most common and debilitating diseases in the advanced
ages. Regarding the fact that knee arthroplsty is the definitive and ultimate
treatment for this disease, we survey the short term result of this modality.
Methods: In this
survey 34 patients with knee arthrosis who have been admitted in Dr ali
shariati university hospital, Tehran, Iran in a five years period (2001-2006)
and have undergone knee arthroplasty. The relationship between, gender and the
operation results were evaluated using the system of knee society knee score
before and after the operation, causes of arthrosis, prosthesis to be used and
the complications of the surgery.
Results: patients
included 20 females and 14 males with the mean age of 67.37±5.25 year and the
age specterum (51-78). In 15 patients the operation was done only in right
knee, in 5 patients in the left knee and in 14 patients both knees were
operated. The mean of functional score of the operated knee reached from 32.68±4.14
before operation (26-45) to 68.67±6.45 after that (59-82) and the mean of knee
score reached from 30.6±3.8 before operation (22-39) to 86.4±6.34 after
operation (73-92).
Conclusion: Regarding
significant improvement in the functional score and the knee score and the low
complication rate of knee arthroplasty it is recommended that in case of
indication this operation be done as soon as possible because late attendance
increases complications.

Background: This study was designed to explore the contribution of risk factors for
coronary artery disease (CAD) in patients with
indication for coronary angiography. Coronary angiography is defined as the
radiographic visualization of the coronary vessels after injection of radio
opaque contrast media. Despite the recognition of risk factors for
CAD, the association between related risk factors and angiographic
findings remains controversial. The aim of the present study was to explore the
association between Gensini scores and major cardiovascular risk factors in
patients with indications for coronary angiography.
Methods: We retrospectively enrolled 495 patients who had
been hospitalized at Dr. Shariati Hospital during September 2009
to September 2010 and had undergone
coronary angiography. The patients were evaluated for the severity of coronary
lesions on the angiogram by Gensini scoring system. The patients were also
evaluated for the presence or absence of DM,
hypertension, family history of cardiac diseases, low HDL,
hyperlipoproteinemia, hypertriglyceridemia and cigarette smoking. Statistical
analysis wad done to find any relationship between Gensini scores and cardiovascular
risk factors.
Results: The study population consisted of 249
men (50.3%) and 245
woman (49.5%) with a mean age of 58.1±10.3
years. A positive correlation
was found between age (P=0.04), sex (P=0.008),
HDL (P=0.04) smoking (P=0.0001)
and diabetes (P<0.013) with Gensini scores.
Conclusion: In
patients with indications of angiography, Gensini scores provide valuable
prognostic information on cardiovascular risk factors. Age, sex, HDL, smoking
and diabetes are related to the severity of coronary
lesions on the angiograms.

Background: One
of the difficulties in acetabulum surgery is appropriate exposure of the site
of surgery. Trochanteric flip osteotomy is one of the surgical methods for
superoposterior and posterior acetabulum exposure. However, due to possible
complications some surgeons prefer to avoid this procedure. This study was
undertaken to determine the outcome of surgical treatment of acetabular
fracture using trochanteric flip osteotomy.
Methods : In this prospective cohort study, 14
patients with acetabular fracture who had
been admitted in Imam Khomeini Hospital in Tehran, Iran, during 2003-2006 underwent trochanteric
flip osteotomy. The patients were followed for at least one year post-surgically.
Demographics, radiologic findings, intensity of pain using visual analogue scale
(VAS),
Harris hip score (HHS), force of hip abductors and complications were noted. Data analysis
was performed using SPSS ver. 13.
Results : The mean HHS was 82.5 (55-95). Heterotopic ossification was observed in three patients. There were
no cases of postoperative infection or non::::union::::. Only two patients showed
displacement of osteotomized fragments. Reduction was anatomic in 10 patients. In one patient, the
force of hip abductors was three-fifth. The mean hip pain was 3.4 based on VAS. There were no cases of
femoral head osteonecrosis. With respect to HHS, the final hip status was
excellent and good in four and six patients, respectively. Three patients had
fair and only one patient had poor condition.
Conclusion: It seems that trochanteric
flip osteotomy has much fewer complications in comparison to other methods justifying
its use in such cases.
Background: Inadequate ventilation, esophageal intubation and difficult intubation are the most common adverse respiratory outcomes in patient undergoing anesthesia .The aim of this study was to compare Mallampati test in supine and sitting positions in traditional approach and during phonation for predicting difficult laryngoscopy and intubation.
Methods: In this study performed in Imam Khomeini Hospital in Tehran, Iran, Mallampati test was performed on 661 patients who met the inclusion criteria for the study. The test was done in supine and sitting positions with and without phonation by a rater who was blind to Mallampati test. Subsequently, laryngoscopy view and difficult intubation were evaluated in the four aforesaid positions by Mallampati test for predicting difficult laryngoscopy and intubation. For each situations, sensitivity, specificity, positive and negative predictive values and accuracy were calculated.
Results: Overall, 28 (4.2%) patients had difficult laryngoscopy and 9 (1.4%) patients had difficult intubation. The highest sensitivity for Mallampati test in predicting difficult laryngoscopy and intubation was in supine and sitting positions without phonation, and the highest specificity was seen in sitting position with phonation. Negative predictive values were more than 95% in all different positions for Mallampati tests and the highest positive predictive value was seen in supine position with phonation.
Conclusion: According to our findings, the highest correlation between Mallampati test and different positions in predicting difficult laryngoscopy and intubation was seen in supine position with phonation. Phonation improved Mallampati score in supine rather than sitting position.
Background: It has been shown that coronary artery calcium scoring (CACS) can be used as a diagnostic method in coronary artery disease (CAD). The relationship between CACS and calcium metabolism in the body has been shown. The arterial calcification is an organized process similar to bone formation which is controled by parathormone (PTH). The relationship between PTH as an osteoregulatory factor and CACS has been also indicated. In this study, we tried to assess the value of serum PTH and CACS in patients planned to undergo coronary angiography (CAG) in order to find a simple, cost -benefit, noninvasive way, for ruling in/out obstructive CAD.
Methods: In a cross sectional study in Imam Khomeini hospital in 1390, CACS by using non-enhanced multi detector computed tomography (MDCT) and measurement of serum level of PTH, Calcium and Phosphate were done in 178 patients suspected to CAD which were scheduled to undergo coronary angiography serum PTH was measured by immuno-radiometric assay (IRMA) and serum Ca and Phosphate were measured by spectrophotometry methods.
Results: Of 178 Patients, 50 patients were females and 126 patients were male. Mean age of them was 56.2±11.6. The correlation coefficient between CACS and Gensini score (0.507, P<0.001), PTH (0.037, P=0.693), Ca (0.062, P=0.499) and Phosphate (0.061, P=0.506) were obtained. The level of serum PTH in the patients with and without coronary artery disease were 21.8±11.6 pg/dl, 23.2±11.5 pg/dl (P=0.427) respectively.
Conclusion: Our study showed association between CACS and CAD that was statistically significant while no relationship was found between PTH, CACS and CAD.
Background: The ability to recognize the severity of the disease in those who their survival depend entirely on admission to the intensive care unit, is very valuable clinically. This study aimed to evaluate the clinical effectiveness of modified sequential organ failure assessment (MSOFA) scale to predict mortality and length of stay in intensive care unit patients respectively.
Methods: This was a retrospective cross-sectional study conducted on hospital records of patients admitted to the intensive care unit. All patients’ records who admitted to the intensive care unit of Kowsar Hospital, Semnan city (the capital of the province), Iran, in 2015 considered as the sample. Collecting data were done during 4 weeks in April and May 2016. The data collection tool was a demographic questionnaire and modified sequential organ failure assessment scale. Exclusion criteria included discharge in the first 24 hours after admission, the patient died a few hours after admission and incomplete information to complete the modified sequential organ failure assessment form.
Results: The study of 105 patients' records of the intensive care unit showed that 45.7% of patients were died, 15.2% and 39% were discharged and moved to other wards respectively. The results of logistic regression analysis and receiver operating characteristic (ROC) curve showed that this criterion had moderate sensitivity and specificity for prediction of mortality and length of stay in ICU patients (Area=0.635, CI= 0.527-0.743) and each unit increase in modified sequential organ failure assessment score is accompanied by increasing 32 percent chance of death (OR=1.325; 95% CI:1.129,1.555; P= 0.001(. Also each unit increase in modified sequential organ failure assessment (MSOFA) score accompanied by increasing 19% length of stay in ICU (OR=1.191; 95% CI: 1.034, 1.371; P= 0.015(.
Conclusion: The results of this study showed that the modified sequential organ failure assessment scale is not useful tool to predict the length of stay and mortality of patients admitted to the intensive care unit.
Results: Overall, 57 patients were evaluated of whom 72% (41 patients) were male. The mean age was 49.9±19.8 (median 53, range 18-94) years. The mean length of stay in the ICU was 13.5±17.5 (median 7, range: 75-75) days. The mortality rate was 17.5% (10 patients). The scores of SOFA, SAPS II, APACHE II, and APACHE IV were significantly higher in deceased patients than in discharged ones. The highest diagnostic accuracy (area under the curve) for all four predicting tools was observed in the second week of hospitalization. On the other hand, SAPS II (74%) on the first day, APACHE-II (76%) on the second day, APACHE-II (82%) on the third day, SOFA (77%) on day 4-5, and SAPS II (82%) on day 6-7 had the highest diagnostic accuracy.
Conclusion: In the present study scores of all four mortality predicting tools at admission were significantly associated with mortality. The accuracy of SAPS II, APACHE IV, and APACHE II are appropriate for estimating prognosis, especially after the second week of admission. |
Results: In this study, 353 people were studied. The mean age of the patients was 36.47±9.1 years, the mean age of onset was 9.2±30.34 years, the mean duration of the disease was 6.20±5.7 years and the mean EDSS score was 2.46±1.8. Estimation errors in the DT model were lower than in the ANN model. The real EDSS score was significantly correlated with scores estimated by DT (r=0.571) and ANN (r=0.623). The mean EDSS estimated by the DT model (2.46±1.1) was not significantly different from the real EDSS mean (P=0.621) but the mean EDSS estimated by the ANN model (2.87±1.3) was significantly higher than the real EDSS mean. (P<0.05). Conclusion: The DT model could better estimate the EDSS score of MS patients than the ANN model and made predictions that were closer to the actual EDSS scores. Therefore, the DT model can accurately estimate the EDSS score of MS patients. |
Methods: This applied-fundamental study was performed on 90 patients with prostate cancer, according to McDonald's criteria who were referred to Shafa Imaging Center in Isfahan, from March 2020 to October 2020. Quantitative analysis is based on modeling the change of concentration of the contrast agent using pharmacokinetic modeling techniques. The pathologist then determined the Gleason score using anatomical landmarks (such as prostate urethra) in the same areas suspected of being cancerous. Existing commercial software captures DCE-MRI data and creates parametric maps such as Ktrans and Kep maps that can be used for diagnostic purposes.
Results: Kep and Ktrans maps showed a significant difference between healthy and cancerous tissue. Kep and Ktrans in prostate cancer were significantly higher than in healthy tissue (P<0.05). Pearson correlation coefficient was used to investigate the relationship between DCE-MRI parameters and histopathological findings. No significant relationship was observed between Gleason score and DCE MRI parameters. Conclusion: DCE MRI parameters significantly improve the accurate diagnosis of prostate cancer and are useful and effective for diagnosis, management, and evaluation of men with prostate cancer, but should not be considered as a substitute for tissue biopsy. |
Results: In this study, the mean (SD) gestational age of participants was 38.56±1.11 weeks. Based on the data, there was a statistically significant relationship between CPR and the infant's need for resuscitation and hospitalization in the NICU (P=0.021) and Apgar score (P=0.042). However, there was no statistically significant relationship between CPR and delivery method, gestational age and birth weight. BPP score was not significantly associated with any of the consequences. Based on the results of the ROC curve, CPR with a cut point of 1.59 with a sensitivity of 88.9% and a specificity of 75% is able to predict the need for resuscitation and hospitalization in the NICU, and with a sensitivity of 83% and a specificity of 54.5%, it is able to predict a low Apgar score. However, BPP score did not have a predictive role in any of the studied parameters.
Conclusion: It seems that CPR examination around delivery can be useful in predicting the condition of the baby immediately after birth and preparing the treatment staff for immediate action. |
Results: The results show that 161 newborns (28.90%) had normal mothers, 89 newborns (15.98%) had diabetic mothers, 117 newborns (21.01%) had hypertensive mothers, and 50 newborns (8.98%) had hypothyroid mothers. One hundred tweny newborns (21.72%) had mothers with preeclampsia, 19 newborns (3.41%) had mothers with epilepsy. Newborns with mothers with epilepsy had the lowest Apgar score of the first minute and the lowest gestational age and newborns with mothers with diabetes had the lowest Apgar score of the fifth minute. Mothers with hypothyroidism had the highest rate of premature rupture of the membranes and mothers with hypertension and preeclampsia had the highest incidence of cesarean section.
Conclusion: Maternal diseases including diabetes, hypertension, preeclampsia, hypothyroidism and epilepsy affect the prognosis of neonates in terms of the severity of prematurity, premature rupture of the membranes, type of delivery, Apgar scores of the first and fifth minutes. Therefore, proper control and treatment of these diseases may improve neonatal prognosis. |
