Abstract
Background: Management of acute abdomen usually does not necessitate accurate pre-operative diagnosis but the surgeon should make a decision about the need for emergent laparotomy. This fact is somehow different for localized peritonitis (e.g. acute appendicitis) in which the clinical presentation directs straightly to the diagnosis. However, acute appendicitis has lots of differential diagnoses, finding the normal appendix during laparotomy is just a start point to look for other diagnoses. Omental torsion is a rare cause for acute abdomen that is usually missed. Knowing about this rare condition and its frequently encountered presentation at the operating room (sero-sanguinous fluid coming out of peritoneal cavity) may prevent missing the diagnosis and doing a malpractice.
Case report: Report a 9 year- old boy presented with acute abdomen which turned out to be an omental torsion after the operation.
Conclusion: Knowledge about this rare condition "omental torsion" and its clinical and intra operative presentations may prevent missing the diagnosis and a malpractice.

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: Gall stone is an important health problem in the world for which different risk factors have been characterized. Gall stone and cardiovascular disease have common risk factors. Homocysteine is accepted as one of the risk factors for cardiovascular disease. We aimed to study the effect of homocysteine level on gall stone formation.
Methods: 54 patients with gall stone-related diseases and 54 patients without stone (control group) were studied from January 2007 to December 2008. Control group consisted healthy subjects with ultrasound proven normal gallbladder. Serum homocysteine level was checked in both groups. Homocysteine level of equal or more than 15 mmol/l was considered as abnormally high.
Results: Cases included 43 women (79.6%) and had mean age of 50.76±15.23 years. Homocysteine level was significantly higher in patients with gallstone in comparison to control group (p=0.014). Risk of gall stone increased 3.4 times in persons who have homocysteine level equal or greater than 15mmol/l (p=0.019). The mean level of homocysteine was higher in men than women (p=0.03). The mean level of homocysteine did not differ significantly in patients with simple gallstone and patients with gallstone-related inflammation disorders (cholecystitis, cholangitis, and pancreatitis). Additionally, one unit increase in BMI level was associated with 1.12 times increase in the risk for gall stone formation (p=0.035).
Conclusion: The homocysteine level is increased in patients with gall stone-related diseases. Homocysteine may be considered as a risk factor of gall stone formation.

Abstract
Background: Apoptin is a protein from chicken anemia virus that could induce apoptosis specifically in the cancer cells but it has not any effect in the normal cells. Phage therapy is a novel field of cancer therapy and phage nanobioparticles (NBPs) such as λ phage could be modified to deliver and express genetic cassettes into eukaryotic cells safely in contrast with animal viruses. The bacteriophages like Lambda could be manipulated to deliver genetic cassettes into eukaryotic cells and express the gene safely. We developed the safe way for the expression of Apoptin gene via Lambda bacteriophage in the human tumors.
Methods: At first the Apoptin clone was produced and then transferred into ZAP-CMV plasmid through BamH-I and HinD-III restriction sites. Then this construct inserted into the Lambda phage in the Escherichia coli host cell. The expression of Apoptin in the recombinant construct was evaluated via RT-PCR and Western Blot analysis. The anti tumor function of expressed protein was measured in the BT-474 cells that was hosted by nude mice.
Results: Transfection of breast carcinoma cells by Lambda bacteriophage containing λZAP-Apoptin-CMV was inhibited the tumor growth significantly but did not any effect on normal cells. The expression of this protein was very high in tumor cells and prevented the death of tumor bearing nude mice. The penetration and spreading of Apoptin construct by bacteriophage Lambda was significantly high but the Apoptin plasmid had very little expression in BT-474 cell, directly. Transfection with NBPs carrying λZAP-CMV-Apoptin significantly inhibited growth of all the breast carcinoma cell lines in vitro, but had no effect on normal cells.
Conclusion: Utilization of recombinant Lambda bacteriophage as a safe expression vector has been confirmed. Apoptin was induced apoptosis specifically in the tumors in vivo. Use of such construct is a very safe way to treat cancer in human. The results presented here reveal important features of λ nanobioparticles to serve as safe delivery and expression platform for human cancer therapy.

Abstract
Background: Traumatic amputation of upper limb above the level of the elbow, are rare injuries that a surgeon may be faced with a handful of cases during his career. Even with advanced techniques in microvascular surgery, the survival of the transplanted limb that cut off completely from the arm is relatively weak.
Case Presentation: Four injured people (patient) in Imam Khomeini Hospital during 1999-2013 in Tehran University of Medical Sciences were treated. Two patients had complete amputation of limb and other patients suffered from complete cutting in artery and vein along with neurological and soft tissue damages. There was not any ischemia or gangrene. However, efficiency of limbs with damages in peripheral nerves was not significant. The main reason was lack of immediate repair of the damaged nerves. In the recent examination, after discharge, the performance of the limb is firstly related to the conditions of the nerve system and secondly it depends on the severity of the injury in each of the muscles. However, none of the patients were dissatisfied of any situation and they were prepared to make any cooperation for improving the condition of their transplanted limb.
Conclusion: Transplantation of the amputated limb can be done in spite of limited resources. Any delay in repairing damaged nerves will result great reduction of final organs’ performance. A limb, made from the own body, always take precedence to prosthesis, even when the efficiency is low.

Abstract
Background: Primary cardiac tumors are rare tumors which should be operated urgently. In this study, cardiac myxoma have been evaluated from diagnosis until dis-charge in a 10 years period and then results including presenting symptoms, approach to the patients were compared with similar study in this center a decade ago.
Methods: Patients who underwent operation for myxoma from year 2003 until 2013 in the Shahid Modarres Hospital were included in this study.
Results: Eighteen patients included in the study, 11 female and seven male. Patients’ ages were in the range of 13 to 76 years (mean 53 years). Mean time from diagnosis to operation was 5.8 days and mean time from surgery to discharge was 8.6±6.1 days. Most common presenting symptoms were first clinical presentation in four patients. In all patents echocardiography was the main diagnostic modality. In addition to trans thoracic echocardiography (TTE), in five patients TEE was used and in 13 patients coronary angiography was used to rule out concomitant coronary artery disease. 94.4% of all tumors (17 cases) were primary cardiac tumors and only one tumor (5.6%) was recurrent. In 16 patients (88.9%) tumor were found in the Left Atrium (L.A) and in one case, tumor was found in both atria and in another case, tumor was in the ventricle. After tumor excision, atrial septum was repaired primarily in seven cases (38.9%) and with pericardial patch in 9 cases. One patient underwent concomitant coronary artery bypass graft (CABG) and another patient underwent concomitant pulmonary valve repair. 14 patients (77.8%) discharged from hospital without any post operative complication. Heart block occurred in one patient and cerebral emboli with secondary cerebrovascular accident (CVA) developed in two patients. One patient died (5.6%).
Conclusion: Comparing results from two similar studies in two consecutive decades revealed that mean time from diagnosis to operation obviously was reduced but ad-vances in diagnostic modalities were unable to change clinical presentation or reduce age of tumor diagnosis or complications or size.

Abstract
Background: Pulmonary valve stenosis (PS) is one of the most common congenital heart disease in children. Isolated pulmonary stenosis is the most common form of pulmonary stenosis. Isolated Pulmonary stenosis is responsible for 8 to 10 percent of congenital heart disease. Balloon valvuloplasty is the choice of treatment for this cardiac disease. One of the most important complications of this disease is pulmonary regurgitation in follow-up. The purpose of this study was to characterize the status of pulmonary regurgitation on follow-up after pulmonary valvuloplasty by balloon. Methods: We studied pulmonary regurgitation after balloon valvuloplasty retrospectively in children less than 14 years old age and isolated pulmonary stenosis. These patients had not complex congenital heart disease and admitted for balloon valvuloplasty during period of September 2001 to September 2011 in Shahid Rajaee Cardiovascular
Research Center. The mean time of follow-up was 7±2.5 years.
Results: Four hundred and fifty-eight patients with mean age of 10.3±8.6 months were studied. Two hundred and fifty-five patients were male and 230 were female. Right ventricular pressure was decreased from 82.3±42.2 mmHg before procedure to 45.2±22.4 mmHg after procedure (P= 0.043). Pressure gradient between right ventricle and pulmonary artery was decreased from 75.4±18.2 mmHg to 25.7±15.13 mmHg during procedure (P= 0.032). The day after procedure, 180 (37.1%) patients had no pulmonary regurgitation echocardiographic evaluation, 175 (36.08%) had mild, and 118
(24.3%) had moderate pulmonary regurgitation. In patients with moderate pulmonary regurgitation, 7 (0.14%) of those improve to severe pulmonary regurgitation. In echocardiographic exam, 12 (2.4%) patients had severe regurgitation the day after balloon valvuloplasty. During long-term follow-up (7±2.5 years) for 3 patient pulmonary valve replacement were performed. In our study, balloon to annulus ratio in three groups of pulmonary regurgitation (mild, moderate and sever) had significant correlation (P=0.012).
Conclusion: Pulmonary regurgitation was seen after balloon valvuloplasty in some patients.In most patients it had no symptoms and long-term follow-up is necessary

Abstract
Background: Tetralogy of Fallot (TOF) refers to a condition in which left ventricular volume is normal or slightly less than normal. Given the differences observed in some Asian patients with TOF, the present study was conducted to investigate left heart by determining Z-scores for the mitral valve in Iranian patients with TOF.
Methods: Eligible subjects in this prospective descriptive study comprised all patients with TOF presenting to Shahid Modarres Hospital in Tehran from March 2012 to March 2015 and diagnosed as the candidates for surgery. After determining the need for surgery and the therapeutic method required, the mitral valve size and Z-scores were calculated. We analyzed sex, age, body surface area (BSA), mitral size (in 2-chamber and 4-chamber view), mitral Z-score, other cardiac anomalies, number of surgery and previous surgery.
Results: Of a total of 80 patients included in the study over 3 years, 29 (36.3%) were male and 51 (63.8%) were female. The mean age of the patients was 7.15±3.37 years and their mitral size was found to be 10-27 mm (16.2±5.99 mm) using echocardiography. Z-scores of the mitral valve were also obtained as -3.09±2.11, ranging between -7.1 SD and +1.3 SD. 58 (72.5%) patients have only TOF and 22 (27.5%) with other cardiac anomalies. 45 patients were for first time underwent surgery and 22 patients for second time, 12 patients for three time and 1 for forth. Of a total of 35 patients had previous surgery, the most common were shunt 15 (42.9%) and then tetralogy of Fallot total correction (TFTC) in 12 (34.3%). Of a total of 80 patients, 59 (73.8%) underwent TFTC, 17 (21.3%) under pulmonary valve replacement and 4 (5%) shunt.
Conclusion: Z-scores of the mitral valve were found to be significantly below the normal value, (i.e. 0±2 SD), in the study patients, suggesting the risk of hypoplastic left heart syndrome in Iranian patients with TOF, nevertheless, the type of TOF examined in these patients might have been different from those observed in other races and regions.

Abstract
Background: Celiac disease is a chronic inflammation of small intestine which is caused by an increased permanent sensitivity to a protein named gluten. This protein is present in some cereals such as wheat, barley, and rye. The immunologic response to this protein can cause clinical symptoms in people with specific human leukocyte antigens (HLAs) (including HLADQ2 or HLADQ8). Most studies have reported an increased incidence of celiac disease in patients with diabetes mellitus type I. This study aimed to determine the prevalence of the celiac disease in patients with diabetes mellitus type I under the age of 18 years old.
Methods: This cross-sectional, analytic descriptive study was performed on forty children with diabetes mellitus type I in Sanandaj Diabetes Association (Kurdistan University of Medical Sciences), Iran, from September 2012 to September 2013. After obtaining consent from their parents, demographic data, including gender, age, family history of diabetes, duration of illness, symptoms of celiac disease, were recorded in the questionnaire. The measurement of the tissue transglutaminase (tTG) antibody and total immunoglobulin type A in the serum was necessary for the screening of celiac disease. Therefore in the laboratory, 5 ml of the venous blood sample was taken and then the serum levels of tTG antibody (from immunoglobulin type A) and total serum levels of this immunoglobulin were measured by the enzyme-linked immunosorbent assay (ELISA) method. Upper endoscopy with multiple biopsies from small intestine was performed in patients with positive serological screening. Finally, the disease was evaluated by histological finding.
Results: Forty children with diabetes mellitus type I included 19 boys (47.5%) and 21 girls (52.5%) were enrolled in the study. The mean age of these patients was 10.53±4.05. The prevalence of celiac disease was 7.5% in these individuals. In the subjects, there was no significant relationship between gastrointestinal symptoms and celiac disease.
Conclusion: In the present study, the prevalence of the celiac disease in type 1 diabetic patients was 7.5% which is higher than the normal population.

Abstract
Background: Health care associated infections (HAIs) are a class of infections that infect patients during hospital admissions and receive medical services. These infections occurs within 48 to 72 hours of admission and up to 6 weeks after discharge. Surveillance of device-associated infections (DAIs) in intensive care units (ICUs) is substantial in planning healthcare strategies. This study was conducted to determine the device-associated infections' burden and antimicrobial resistance patterns.
Methods: In this descriptive-analytic study, three common device-associated infections included central line-associated bloodstream infection (CLA-BSI), ventilator associated pneumonia (VAP), and catheter-associated urinary tract infection (CA-UTI), were assessed in intensive care units of Besat Hospital in Hamedan from April 2017 to April 2018. In order to determine the incidence of device-associated infections, the number of device-associated infection cases was calculated during the study period and divided into the number of device-days used. The device-days included all days of exposure to that device (vascular catheter, endotracheal tube (ventilator), or urinary catheter) in all patients in the study population.
Results: Out of 1806 intensive care unit admitted cases, 168 patients (9.3%) were device-associated infection with distribution of 92 cases (55%) of ventilator-associated pneumonia (VAP), 56 cases (34%) of catheter-associated urinary tract infection (CA-UTI) and 20 cases (11%) of central line-associated bloodstream infection (CL-BSI). The incidence of VAP, CA-UTI and CL-BSI was 44.7, 17.5, and 21.61 days, respectively. The most organisms were Acinetobacter (27.4%), Klebsiella (18.3%), Escherichia coli (E. coli) (15.4%). Vancomycin-resistant enterococcus (VRE) was 75%. Acinetobacter resistance to colistin and carbapenem was 16.8%. About half of Pseudomonas isolates were resistant to meropenem.
Conclusion: According to the present findings of this study, a high incidence of device-associated infections and resistant organisms in our intensive care units were documented, which represents a need to reinforce the preventive and control programs. Various results in different studies can be due to differences in the level of health care in different centers and countries.

Abstract
Background: SLC39A6 Protein (solute carrier family 39) or LIV-1 is a zinc transporter protein that is overexpressed in positive estrogen cancers such as breast cancer. The LIV-1 protein transfer zinc into the cytoplasm through the plasma membrane. Today it is known that just as a decrease in the concentration of zinc in the cell can cause cancer, an excessive increase in the concentration of zinc can also stimulate irregular cell division and caused cancer. Thus, inhibition of zinc transporter protein may play a role in preventing malignancies and metastasis. It can also be used as a diagnostic marker in the diagnosis of cancers in various laboratory methods. The present study was performed to prepare a polyclonal camel antibody for the detection of LIV-1 protein at the cell surface.
Methods: This study was started in the Pasture Institute of Iran in 2018 September and finished in February 2020. An expression construct containing the human LIV-1 gene was prepared and transferred to the E.coli BL21 by chemical (CaCl2) and heat shock method. The expression of the protein was induced by IPTG and then protein was purified by affinity (Ni-NTA) chromatography. After preparing recombinant protein one female camel was immunized, 6 times at two weeks intervals with Freund's adjuvant. After immunization, the isolated polyclonal antibody was evaluated by ELISA, western blotting and flow cytometry in the detection of LIV-1 protein.
|
Results: The result showed that LIV-1 protein was well purified and also the camel polyclonal antibody was able to detect LIV-1 protein in ELISA, western blot and also it can detect LIV-1 on the cell surface as shown by flow cytometry test.
Conclusion: In recent years, LIV-1 has been shown to be a good candidate as a marker in breast cancer, so polyclonal antibodies against LIV-1 can be used for early detection of breast cancer by various diagnostic methods. In this study, it has been shown that polyclonal camel antibodies can be used in laboratory methods and can be considered for immunological tests and therapeutic applications.

Abstract
Background: Congenital heart defects (CHD) are the most common type of birth defects. The main screening tests used to identify babies with congenital heart defects include prenatal echocardiography and postnatal clinical assessment. Routine pulse oximetry has been reported as an additional screening test that can potentially improve the early diagnosis of critical congenital heart disease (CCHD).
Methods: This study is a multi-stage evolutionary study that was conducted for 12 months from March 2021 to March 2022 at Pediatric Cardiovascular Research Center in Cardiovascular Institute, Isfahan, Iran. In the first phase, after identifying the topic and aims of the present study, questions were designed through the PICO method including (population, intervention, control, and outcomes). Then conducting systematic searches, the quality of all existing clinical guidelines (CG) of this field were evaluated using the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument and a committee consisting of pediatric cardiologists and neonatologists in the field. Next, based on the opinions of experts, the quality of 1 out of 6 clinical guidelines for early detection of critical congenital heart disease at birth by pulse oximetry was assessed as optimal. Finally, the clinical guidelines draft was evaluated using the Delphi method and the panel of experts. After expert panel meetings and consensus between members, the final version of the guideline for early detection of critical congenital heart diseases at birth by pulse oximetry was developed.
|
Results: In the present study, criteria of clinical practice regarding the stages of newborn screening by pulse oximetry at birth were determined based on the evidence and health conditions and were presented in twenty-eight recommendations and six sections. The final recommendations were presented in the results section.
Conclusion: The finding of the present study showed that physicians, nurses, and midwives can apply the recommendations of this clinical guideline for the early detection and referral of neonates with critical congenital heart disease.

Abstract
Background: Isokinetic dynamometry is a golden standard test to estimate lower extremity sport related injuries in the athlete assessment. Dynamometry is also commonly used to design preventive protocols. The aim of this study was to explore the effects of hip joint positioning in seated and lying positions on knee joint dynamometry indices, including extensor and flexor peak torques in football and track and field athletes.
Methods: Forty four male athletes (including 22 football players and 22 track and field athletes) have participated in this descriptive-analytic study. The sampling method was simple nonrandom sampling. This study was conducted in the Biomechanics laboratory of the Rehabilitation Sciences, Faculty of Tabriz University of Medical Sciences since October 2019 to October 2020. Knee joint dynamometry indices were consisted of concentric and eccentric flexor and extensor peak torques at 60 degrees per second velocity. Optimum length, angle of crossover, and the muscle balance ratios (concentric extensor peak torque/concentric flexor peak torque and eccentric extensor peak torque/concentric flexor peak torque) were also evaluated. All assessments were performed in both seated and lying positions. The indices were compared between football players and track and field athletes.
|
Results: The interaction effect of group and hip joint was not significant (P<0.05). Further, concentric and eccentric flexor and extensor peak torques and conventional flexor to extensor ratio were higher meaningfully in the seated position compared to the lying (P<0.05). Optimum length was significantly higher in the lying position, but the angle of crossover was higher in the seated position (P<0.05). The hip joint position was not effective on the functional flexor to extensor ratio (P>0.05). Also, dynamometry indices were not different between football and track and field groups (P<0.05).
Conclusion: Findings revealed the effects of hip joint position on strength measurements in football and track and field athletes. This factor should be considered to design strengthening exercises for athletes and also to estimate the sport injury risk.
