Single-incision laparoscopic cholecystectomy (SILC) is a newly developed method of performing cholecystectomy and has been increasingly used. The aim of this study is to see if SILC has any advantages over conventional (three-port) laparoscopic cholecystectomy (CLC).

In this cross-sectional study, 52 patients who underwent SILC (group A) during the period from May 2011 to March 2013 were compared with 62 patients who underwent CLC (group B) at two centers affiliated to Shiraz University of Medical Sciences in Shiraz, Iran. Data were gathered on operation time, pre- and postoperative complications, patients' postoperative pain, pain reliever use, duration of hospital stay, and return to work, and these data were compared using SPSS software version 16.

The mean age of patients was 38.01 ± 13.24 in group A and 44.82 ± 15.11 in group B. Mean body mass index (BMI) was 23.97 ± 4.78 and 26.22 ± 4.67 in groups A and B, respectively. The mean operation time was 76.4 ± 29.0 min in group A and 72.9 ± 24.1 min in group B (P = 0.496). Preoperative complications were 3.8% in group A and 0 in group B (P = 0.206). Postoperative complications were 17.3% in group A and 11.3% in group B (P = 0.423). The mean for early postoperative pain revealed no significant difference (P = 0.814), but the mean pain on discharge was significantly higher in group A patients (P = 0.034). Regarding the mean admission time and return to normal activity, we found no significant differences.

SILC does not have any special advantages over CLC with regard to surgical outcomes, but it can be a safe alternative to CLC, especially in patients concerned about cosmoses.

46, XX gonadal dysgenesis without the phenotype of Turner's syndrome is described as "pure". Although, previous investigations obtained that commonly gonadal dysgenesis did not cause breast development as a result of low levels of circulating estradiol. However, in this study, we aimed to report a familial pure gonadal dysgenesis with and without normal secondary sexual characteristics. In this study, we reported three siblings with pure gonadal dysgenesis with and without normal secondary sexual characteristics. The elder two sisters had a normal female phenotype and the youngest had amenorrhea with no breast development (B1) and pubic hair. In addition, it seems that the absence of pubic hair occurred due to delayed constitutional puberty. According to results, it seems that clinicians should consider different presentations for pure gonadal dysgenesis with familial pattern.

Schwartz-Jampel syndrome (SJS), first described in the United States in 1962, is a hereditary disorder characterized by facial dysmorphism and muscle stiffness. We describe the first case of a Persian 9-year-old boy with SJS and review the literature. The child had a short neck, blepharophimosis, flattened face, hypertrichosis of the eyelids, prominent eyebrows, high arched palate, low set ears, micrognathia, short stature, and skeletal deformities. He had proximal muscle hypertrophy, distal muscle wasting and generalized hyporeflexia. Bone X-ray revealed pseudofracture of humerus. Needle electromyography revealed continuous myotonic discharges at rest with no waxing and waning in all tested muscles. Based on clinical and electrodiagnostic findings, the diagnosis of SJS type 1B was made and procainamide was started which resulted in clinical improvement. The diagnosis of SJS should be suspected when a child presents with the triad of myotonia, facial dysmorphism and skeletal deformities.

Aphasia is a language disorder caused by left hemisphere damage. For treatment of aphasia, in some of therapeutic approaches, the right hemisphere (RH) abilities, such as, emotional perception, is used for stimulation of the language process in the left hemisphere. The aim of this study is to investigate emotional word repetition in aphasia after a stroke, in Persian language patients.

Fifteen aphasic patients (eleven male and four female) between 45 and 65 (58/4 ± 7/8) years of age, participated in this cross-sectional study. A list of 20 emotional words and a list of 20 neutral words as stimuli were prepared and the patients were asked to repeat each word after five seconds; if a patient needed to repeat a word again, it was repeated for him/her again, and the total score for each subject was calculated. The paired t-test was used to test group mean differences and the significant level was 0.05.

The mean and standard deviation for emotional word repetitions were 6.93 ± 1.72 and for non-emotional word repetition was 7.10 ± 2.23, and the P value = 0.892, thus, no significant difference between emotional and non-emotional word repetitions was noticed. The mean and standard deviation for the positive emotional word repetitions were 3.53 ± 3.29 and for negative word repetitions were 3.40 ± 3.56, (P = 0.751), with no significant difference between positive and negative emotional word repetitions.

Despite the main hypothesis that the right hemisphere is involved in the processing of emotions, it can be stated that both hemispheres are involved in the processing of emotional words, albeit in a different and probably complementary manner.

Multiple sclerosis (MS) is a multifactorial disease that could result from demyelination of the myelin sheath. The aim of this study is to investigate the demographic features and  rank the immunomodulating drugs in patients with MS.

This study was conducted in the MS clinic of the Isfahan Kashani Hospital, from 22 May, 2011 to 18 March, 2013. The data analyses (n = 1067) were divided  into two periods: (1) 2011/05/22 to 2012/03/18 denoted as P1 and (2) 2012/04/02 to 2013/03/18 denoted as P2.

Most of drugs prescribed within the population studied were: Avonex, Betaferone, and Rebif. There was an increase in the number of female (n = 811) and male subjects (n = 256). During P1/P2 there was an increase from 460 to 607 in the total number of patients, respectively. The number of patients who attended the MS clinic once was 250 (P1) versus 430 (P2), and those more than four times was 71 (P1) versus 59 (P2) correspondingly.

The number of females increased from 2011 to 2013. Because of dissimilar ingredients additive of different pharmaceutical companies, it could be suggested that pharmacotherapy strategies, especially in Iranian population of MS with first-line treatment using Avonex, Betaferone and Rebif, more spotlighted on inter- and intra-individual variability based on clinical pharmacokinetics parameters.

Previous publications reported that an individual's month of birth (MOB) might have an important correlation to that consequent risk of multiple sclerosis (MS).

The aim of this preliminary study was to investigate the distribution of different MOBs inpatients with MS in Isfahan, Iran.

This investigation was conducted to the Isfahan Neurosciences Research Centre. 1283 patients with MS were studied. Clinical data were recorded in d-Base and analyzed using SPSS (version 18) for Windows.

Of the total population studied there were 979 females and 304 males. The mean age of all the patients was 34.6 years (range 10-87 years). Within the total population, the MOBs in the 62% of patients were in the season's spring and summer, and in 38% of patients they were in the season's autumn and winter. As the MOB might be recognized to have a bearing on an individual's risk of contracting MS, the highest and lowest correlations seem to be linked with April, September, May (↑), and November (↓), respectively.

The seasonal relationship between MOBs and MS risk might be pointed toward a potential function for vitamin D throughout pregnancy or the early life of the newborn. Further studies are needed to confirm these correlations.

End stage renal disease (ESRD) is a state of micro inflammation that attenuates patient's life span and quality of life. Inflammatory markers like interlukin 6 (IL-6) and C- reactive protein (CRP) can predict inflammatory state in ESRD patients. Dietary limitations are risk factors for omega-3 deficiency in these patients. Omega-3 supplementation is an attractive material that proposed in inflammation modulation. The aim of this study is evaluation of effect of omega-3 supplementation on IL-6 and CRP level in chronic ambulatory peritoneal dialysis (CAPD) patients.

This randomized controlled double-blind clinical trial is performed in 40 CAPD patients in two academic hospitals in Isfahan, Iran. One group received 1000 mg omega-3 capsule (each capsule contains 180 mg Eicosapentanoic and 120 mg Dosahexanoic acid) three times a day orally for 8 weeks (n = 20) and the other matched group by placebo (n = 20). Serum level of IL-6 and quantitative CRP (Q-CRP) were measured in beginning and the end of the study. Finally all data were analyzed by SPSS version 18.

Mean age of patients was 53 years old in omega-3 group patients and 54 years old in placebo group. There were not any differences in CRP and IL-6 level in the beginning and the end of study between two groups (P: 0.81 and 0.10 for CRP and 0.26 and 0.23 for IL-6, respectively).

Omega-3 supplementation did not effect on inflammatory markers (Q-CRP and IL-6) in CAPD patients after 8 weeks.

There are many factors that affect the quality of life, for example, stress and the coping strategies. Polycystic ovary syndrome is a common hormonal disorder leading to menstrual disorders, hirsutism, acne, obesity, infertility and abortion. In such cases, the patients suffer from a variety of stresses and face problems in their coping strategies with life's problems which can affect the quality of life and cause psychological distress and low the quality of life. The quality of life is a descriptive term which points to health and emotional, social and physical promotion of individuals as well as their ability to perform daily living tasks. The purpose of this study was to investigate the relationship between quality of life and coping strategies in patients with polycystic ovary syndrome.

To perform this study, randomly 200 women who had inclusion criteria and were referred to Ali Shariati Hospital in Isfahan were selected and responded DLQI questionnaire and Carver coping strategies and form of demographic characteristics.

The mean score of quality of life in the patients was 4.14 ± 5.57. It was shown that acne has no effective role on quality of life and coping strategies in contrast in hirsute and non-hirsute patients; there was a significant difference in quality of life P value < 0.001). Also there is a significant relationship between the quality of life and coping strategies (problem solving, cognitive, emotional and social support) (P < 0.05) and quality of life has the highest correlation with emotional strategies (r = 0.46).

According to results of this study, patients with PCOS are at risk pcychologicla disorders that may be led to decrease of quality of life. Thus this patients need to support by oppositions strategies. Also not only physical treatment but also psychological surveillance especially social support must be done for them.

Cystic lymphangioma (CL) is a benign lymphatic malformation mostly seen in the head and neck of neonates and infants. Abdominal CL is an unusual entity which may present in omentum, mesentery, abdominal wall, or solid organs. The authors present an unusual case with two separate abdominal cystic lymphangiomas.

Herpes zoster is an infectious disease with neurological complications caused by reactivation of varicella zoster virus in dorsal root ganglia of spinal cord which is also known as "Shingles." Suppression of immune system is the major predisposing factor for reactivation of latent virus. Disease is mainly characterized by rash, vesicles and pain along one or more dermatomes which are innervated from one or more spinal nerve roots. Complications may be present after a while despite of patient treatment. Motor involvement is included. Some previous studies showed segmental zoster paresis as a rare complication, a few weeks after first presentation, among immunocompetent individuals. We present post herpetic motor involvement of C5 and C6 in a 59-year-old woman who underwent chemotherapy and radiotherapy due to breast cancer, manifesting left upper limb weakness and paresis, 6 months after left partial mastectomy. Segmental paresis of zoster virus should be considered as a cause of motor impairment in an immunocompromised person suffering from shingles.

Cryptorchidism is a common problem which is prevalent in 3% of male infants. This study aimed to determine the effect of both trans fixation and Dartos pouch fixation methods on the postoperative recurrence rate and testicular changes.

In a clinical trial study, 70 children were randomly divided into two groups. In the first group, the correction of cryptorchidism was done by Dartos pouch without suture and in the second group; testis was sutured using common trans fixation. The size of testicles was measured before and 6 months after surgery, children were followed on postoperative complications, trauma to testicles and recurrence of disease in both groups. Data were analyzed using SPSS soft ware.

The mean size of testicles was 87.16 ± 20.6 mm2 in the group with fixed testicle and 182.4 ± 37.9 mm2 in the group with not-fixed testicle before operation and the difference between the two groups was significant (P &#61; 0.013). After surgery, the mean size of testicles was 90.8 ± 19.9 mm2 in the group with fixed testicle and 183.7 ± 41.2 mm2 in the group with not-fixed testicle and the difference between them was significant (P &#61; 0.026). The average of changes in testicular size was 3.62 ± 1.93 and 1.25 ± 5.35 mm2 in both fixed and not-fixed groups, respectively and changes in testicular size had no significant difference between the two groups. (P &#61; 0.68).

Type of fixation had no effect on the size of testes or relevance to the level of retraction. The above management protocol did very well in our hands, and we recommend it for application in the management of undescended testis.

The present study was designed to investigate the association of GH and LEP genes': single-nucleotide polymorphisms with fat-tail measurements (fat-tail dimensions) in Makooei sheep.

DNA was extracted from whole blood samples collected from 100 sheep. Polymerase chain reaction (PCR) products were subjected to single-strand conformation polymorphism (SSCP) denaturation and polyacrylamide gel electrophoresis. Data were collected at the Makooei Sheep Breeding Station in Makoo (36°, 35′S and 48°, 22′E) of West Azerbaijan province. Climatically, this location has temperate summers and cold winters and receives a mean annual rainfall of about 400 mm. Ewes are raised in an annual breeding cycle starting in September. In general, the flock is managed under a semi-migratory system.

In the tested Makooei sheep population, significant statistical results were found in all traits of fat-tail measurements for GH and LEP genes. Individuals with the G4, L4 genotype of GH and LEP genes had lower tail length (rump length), fat thickness (the thick rump), and tail width (rump width) when compared to those of individuals with other genotypes (P &#60; 0.05). In addition, the results demonstrated that individuals with the G5, L5 genotype of GH and LEP genes had superiority of tail length (rump length) and fat thickness (the thick rump) compared to those individuals with other genotypes (P &#60; 0.05). Individuals with the G2, L2 genotype of GH and LEP genes had superiority of tail width (rump width) compared individuals with other genotypes (P &#60; 0.05).

These results confirmed potential usefulness of GH and LEP genes in marker-assisted selection programs of sheep breeding.

Although tobacco, alcohol abuse are well-recognized risk factors for oral squamous cell carcinoma (OSCC), there is evidence to indicate that herpes simplex virus (HSV) may also play some inducing role. The purpose of this study was to investigate the presence of HSV in Iranian patients with OSCC using the polymerase chain reaction (PCR).

Biopsies of OSCC were obtained from 60 patients, 54 males and 6 females, aged between 36 and 80 years old. Paraffin-embedded, histologically confirmed specimens were analyzed for the presence of HSV DNA using PCR.
>

Only three samples (5%) was positive, suggesting that HSV may not play an important role in this group of patients.

The prevalence of HSV-1 positive sample in this study was 5%. It shows that HSV-1 has no important role in OSCC.

Segmentation of leukocytes acts as the foundation for all automated image-based hematological disease recognition systems. Most of the time, hematologists are interested in evaluation of white blood cells only. Digital image processing techniques can help them in their analysis and diagnosis.

The main objective of this paper is to detect leukocytes from a blood smear microscopic image and segment them into their two dominant elements, nucleus and cytoplasm. The segmentation is conducted using two stages of applying K-means clustering. First, the nuclei are segmented using K-means clustering. Then, a proposed method based on region growing is applied to separate the connected nuclei. Next, the nuclei are subtracted from the original image. Finally, the cytoplasm is segmented using the second stage of K-means clustering.

The results indicate that the proposed method is able to extract the nucleus and cytoplasm regions accurately and works well even though there is no significant contrast between the components in the image.

In this paper, a method based on K-means clustering and region growing is proposed in order to detect leukocytes from a blood smear microscopic image and segment its components, the nucleus and the cytoplasm. As region growing step of the algorithm relies on the information of edges, it will not able to separate the connected nuclei more accurately in poor edges and it requires at least a weak edge to exist between the nuclei. The nucleus and cytoplasm segments of a leukocyte can be used for feature extraction and classification which leads to automated leukemia detection.

Aloe verahas antioxidant, antiinflammatory, healing, antiseptic, anticancer and antidiabetic effects. The aim of the present study was to design and evaluate the formulation of Aloe verachewing gum with an appropriate taste and quality with the indications for healing oral wounds, such as lichen planus, mouth sores caused by cancer chemotherapy and mouth abscesses as well as reducing mouth dryness caused by chemotherapy.

In Aloe verapowder, the carbohydrate content was determined according to mannose and phenolic compounds in terms of gallic acid. Aloe verapowder, sugar, liquid glucose, glycerin, sweeteners and different flavors were added to the soft gum bases. In Aloe verachewing gum formulation, 10% of dried Aloe veraextract entered the gum base. Then the chewing gum was cut into pieces of suitable sizes. Weight uniformity, content uniformity, the organoleptic properties evaluation, releasing the active ingredient in the phosphate buffer (pH, 6.8) and taste evaluation were examined by Latin square method.

One gram of Aloe verapowder contained 5.16 ± 0.25 mg/g of phenolic compounds and 104.63 ± 4.72 mg/g of carbohydrates. After making 16 Aloe verachewing gum formulations, the F16 formulation was selected as the best formulation according to its physicochemical and organoleptic properties. In fact F16 formulation has suitable hardness, lack of adhesion to the tooth and appropriate size and taste; and after 30 min, it released more than 90% of its drug content.

After assessments made, the F16
formulation with maltitol, aspartame and sugar sweeteners was selected as the best formulation. Among various flavors used, peppermint flavor which had the most acceptance between consumers was selected.

Human basic fibroblast growth factor (hBFGF) is a heparin-binding growth factor and stimulates the proliferation of a wide variety of cells and tissues causing survival properties and its stability and biological activity improvements have received much attention.

In the present work, hBFGF produced by engineered Escherichia coliand purified by cation exchange and heparin affinity chromatography, was PEGylated under appropriate condition employing 10 kD polyethylene glycol. The PEGylated form was separated by size exclusion chromatography. Structural, biological activity, and stability evaluations were performed using Fourier transform infrared (FITR) spectroscopy, 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide (MTT) assay and effect denaturing agent, respectively.

FITR spectroscopy revealed that both PEGylated and native forms had the same structures. MTT assay showed that PEGyalated form had a 30% reduced biological activity. Fluorescence spectrophotometry indicated that the PEGylated form denatured at higher concentrations of guanidine HCl (1.2 M) compared with native, which denatured at 0.8 M guanidine HCl.

PEGylation of hBFGF makes it more stable against denaturing agent but reduces its bioactivity up to 30%.

The presence of estrogen receptor alpha has been reported in the cell and tissue levels in gastric cancer; however, its impact on patients' survival remains unclear. The aim of this study was to investigate the expression of estrogen receptor in gastric carcinoma as well as its relationship with the clinicopathologic findings of the patients.

The study was performed on 100 endoscopic biopsies of gastric adenocarcinoma for estrogen receptor expression using an immunohistochemical method, and their relationship with the clinicopathologic findings of the patients, such as age, gender, tumor site, size, grade, depth of tumor invasion (T), and lymphatic status (N), were analyzed using independent sample t-test and Pearson Chi-square test. A P < 0.05 was considered significant in all analyses.

Using an immunohistochemical method on endoscopic biopsies of 74 males and 26 females with the mean age of 63 years, estrogen receptor was found to be positive in 41% of patients. No significant difference was found between estrogen receptor expression and other clinicopathologic findings (P = 0.75). There was a significant difference between estrogen receptor (+) and estrogen receptor (−) groups in nodal involvement (P = 0.001). The estrogen receptor (+) patients had more number of lymph nodes involved.

This study showed that lymph node involvement has a significant relationship with estrogen receptor expression. However, no significant relationship was found between estrogen receptor expression and other clinicopathologic findings such as age, gender, tumor site in stomach, tumor size, tumor grade, and T-stage.

In this study, we aimed to investigate the effectiveness of silver nitrate (SN) versus tetracycline in pleurodesis among patients with malignant pleural effusion (MPE).

In this prospective randomized clinical trial, patients with unilateral MPE candidate for pleurodesis were enrolled. The patients randomly allocated in two groups for receiving 20 mL 0.5% SN or 2.5 g tetracycline diluted in 30 cc normal saline and 0.1% lidocaine, through the chest tube. Patients were followed-up immediately (during 24 h) and 1-month after the procedure for evaluating recurrence of the pleural effusion using chest radiograph. They were clinically evaluated for chest pain and/or dyspnea and fever using a questionnaire that completed by the surgeon. The results were compared with two groups.

During this trial, 50 patients with MPE candidate for pleurodesis were selected and randomized into two interventional groups (25 patients in each group). Immediate and late recurrence of pleural effusion after pleurodesis were similar in two groups (P > 0.05). All patients in tetracycline group had fever and chest pain, but in SN group fever and chest pain were reported in 3 (12%) and 12 (48%) of patients, respectively (P < 0.05).

SN is at least as effective as tetracycline for MPE treatment. In addition, its side effects were lower than tetracycline. Other advantages of SN are its low cost, availability, and safety. For more accurate results, it is recommended to design further trials with larger sample size and with lower doses of both SN and tetracycline.

The zinc finger transcription factor zinc finger protein, X-linked (ZFX) acts as an important director of self-renewal in several stem cell types. Moreover, ZFXexpression abnormally increases in various cancers and relates to tumor grade. We performed this study, to examine its role in the pathogenesis of astrocytoma and meningioma.

We used real-time reverse transcription polymerase chain reaction method for evaluation of ZFXexpression in 25 astrocytoma tumoral tissue and 25 meningioma tumoral tissues with different WHO grades. Furthermore, the association of gene expression with various clinic-pathological characteristics was examined.

We found that there is a significant association between gene expression and different tumor grades, the presence or absence of invasion, forming and nonforming of glomeruloid vessels, the age over or under 50 and the presence or absence of calcification in astrocytomas. This is the first report that shows that ZFXwas directly correlated with the central features of the neoplastic phenotype, including the growth of cancer cells, angiogenesis, and invasion.

Regarding all the above-mentioned studies, it is highly plausible that silencing the expression of ZFXgene in gliomas has a major role in the therapeutic interventions of the disease in future.

The incidence of urinary stone disease has shown a steep rise in recent decades along with marked modifications in dietary habits and life- style. There has been an increased prevalence of urinary stone disease in patients with diabetes. We took up this study to determine the association of diabetes mellitus with kidney stones in patients undergoing surgical treatment.

Patients presenting with renal stones for surgical management formed the study group. Body mass index (BMI) was calculated by noting the weight and height of the patient. The extracted stone/stone fragments were analyzed to determine the chemical composition. Urinary pH was similarly noted in all.

The mean BMI among the diabetics was 26.35 ± 5.20 (range 17.75-35.60), whereas the mean BMI among the non-diabetics was 23.41 ± 2.85 (range 17.71-31.62) (P < 0.0004). The incidence of uric acid calculi in the diabetics was significantly high (P < 0.03). The mean urinary pH among the diabetics was 5.61 ± 0.36 and among the non-diabetics was 6.87 ± 0.32, which was significantly lower (P < 0.000044).

There is a strong association between type 2 diabetes and uric acid stone formation. There is also a strong association between diabetes mellitus, BMI, and also with lower urinary pH.

Hypotension is a serious and the most common adverse effect of spinal anesthesia. Many studies have focused on prevention of hypotension due to spinal anesthesia. The aim of this study was to compare the efficacy of three different methods of using colloid, ephedrine and wrapping of extremities on the incidence of hypotension and bradycardia following spinal anesthesia in patients undergoing elective lumbar disc surgery in knee–chest position.

A total of 180, ASA (I–II), adult patients candidate of lumbar disc surgery in one or two levels who met the inclusion criteria were randomly allocated in one of three treatment groups of receiving Voluven (6% hydroxyethyl starch 130/0.4 in 0.9% sodium chloride injection), ephedrine and leg wrapping. After establishment of spinal anesthesia, patients were outsourced and knee–chest position was done. Heart rate and blood pressure of patients were recorded at different times till 60 min after spinal injection. Statistical analyses of data were performed with SPSS (version 20) and by considering groups, values of P < 0.05 were considered statistically significant.

Mean systolic blood pressure (119.5 ± 7.4± mmHg) and mean heart rate (71.7 ± 6.7± b/min) were higher in a group receiving Voluven (P < 0.05). The Voluven group significantly experienced less nausea and vomiting in recovery room in comparing with other groups (P = 0.027). They also received significantly less ephedrine (P = 0.012) and ondansetron [12 (20%)] (P = 0.02). Furthermore, patients receiving elastic bandage had significantly more blood loss than the other groups (P = 0.013).

Colloid therapy was the most effective method in keeping hemodynamic stability, prevention of decrease in systolic blood pressure and incidence of side effects during spinal anesthesia for lumbar disc surgery in knee–chest position.

Serum antimullerian hormone (AMH) proposed to be a reliable marker of ovarian reserve; the aim of this study was to evaluate the influence and value of laparoscopic management in endometriosis as measured by serum AMH levels.

In this cross‑sectional study, 33 infertile patients who referred to fertility ‑ Infertility Center of Isfahan ‑ with different stages of endometriosis managed by diagnostic operative laparoscopy and serum AMH levels were measured pre and one month postoperative laparoscopy. Main outcome measures were serum AMH levels in correlation with the type of infertility, stage of endometriosis, and type of surgery in infertile patients.

33 infertile patients enrolled in the study with mean age 28.9 ± 5 years, and thus did not show a significant difference. Mean serum AMH levels was 4.23 ± 3.75 ng/ml and 2.2 ± 2.47 ng/ml, respectively, in primary and secondary infertility groups before and one month after laparoscopy, which shows a significant difference (P < 0.001). Median AMH level changes in Cauterization (0.67 ± 0.76 ng/ml), endometrioma excision 2 ± 0.6 ng/ml, both 2.18 ± 0.81 ng/ml and shows no significant differences. Mean serum AMH levels were definitely decreased in minimal/mild and severe stage endometriosis before and 1 month after laparoscopy, (1.84 ± 2.06 ng/ml and 2.18 ± 3.45 ng/ml), respectively. Also serum AMH according to ovarian appearance and evolvement showed no significant differences after laparoscopy: (5.5 ± 1.4 ng/ml and 2.76 ± 0.96 ng/ml) and (3.37 ± 2.2 ng/ml and 1.84 ± 1.5 ng/ml).

Serum AMH levels clearly decreased 1 month after operative laparoscopy.

Preeclampsia (PE) is the most common cause of maternal death in the world. Some studies showed that inadequate intake of foods rich in antioxidant leads to increase oxidative stress and adverting obstetrical outcomes. The aim of the present study was to investigate the relationship between antioxidant status and dietary nutrient intake in pregnant women with PE.

This cross-sectional study was conducted among 55 pregnant women with PE admitted in the Obstetrics and Gynecology department of Shahid Beheshti Hospital in Isfahan, Iran. The subjects were interviewed about demographic data and dietary intakes by using a 168-items semi-quantitative food frequency questionnaire (FFQ). The total antioxidant capacity (TAC) of this serum was measured by using a double-antibody sandwich enzyme-linked immune-sorbent assay (ELISA). Nonparametric correlation statistics were used to meet assumptions of normality and equal variances.

Total antioxidant status was significantly higher in comparison with healthy pregnant women (which measured as pilot). Intake of vitamin E was below the dietary reference intakes, and was positively associated with serum TAC (r = 0.367, P = 0.003), but this correlation was significantly negative about dietary selenium. There wasn't any significant correlation between intake of vitamin C, β-carotene, riboflavin, copper and serum TAC.

Our findings showed that intake of vitamin E was positively associated with serum TAC. Little support was found on a relationship between dietary intakes of other micronutrients and serum TAC. Further research is required to explore the relationships between maternal nutrient intake and antioxidant status in women with PE.

Fibrocalculous pancreatic diabetes has distinctive features like younger age at onset, presence of large intraductal calculi, aggressive course of the disease, and proneness for pancreatic cancer. Pancreatic calculi are the hallmark for the diagnosis. We report a 32-year-old male patient, a known case of diabetes since 2 years, presented with recurrent pain abdomen, malabsorption, and neuropathic symptoms. The diagnosis was established on the basis of clinical examination, biochemical and radiological investigations. He was prescribed two doses of premix insulin and pancreatic enzyme supplements for relief of abdominal pain and steatorrhea.

Brain abscesses caused by Nocardiaare rare but have a very high mortality and specific requirements of antibiotic treatment. Nocardial brain abscesses are mainly found in patients with predisposing conditions such as pulmonary alveolar proteinosis (PAP), a disease associated with chronic exposure to silica dust. We present a case of multiple nocardial brain abscesses in a man with PAP probably due to long-term occupational exposure to silica dust. Conclusively, in patients presenting brain abscesses and a history of chronic exposure to silica dust, PAP and opportunistic nocardial infection should always be considered as possible diagnoses.

Ureteropelvic junction obstruction (UPJO) is the most common cause of hydronephrosis within childhood that usually treat by surgery. According to anatomical variations in different individuals, scheduling similar procedures for all patients is not suitable, and thus the best decision for an appropriate surgical technique should be considered separately for each patient. Regardless of the type of applied technique, creating a funnel-shape UPJ with a suitable size is a successful treatment. In this context, the assessment of a successful surgical treatment in a short-term follow-up means repairing revealed anatomical defects. The present study aimed to compare the diagnostic value of static magnetic resonance urography (MRU) and diuretic-based renalscintigraphy (DRS) in patients with UPJO after pyeloplasty.

A total of 30 consecutive patients with UPJO, who underwent unilateral pyeloplasty between 2012 and 2013 were assessed. All subjects underwent DRS and also MRU about 1-month after the former procedure.

The Kendall's tau correlation showed a very strong correlation between results of MRU and diuretic renal scintigraphy (r = 0.932, P < 0.001). This strong correlation was also shown by Somers'd test (r = 0.932, P < 0.001) similarly.

Our study shows a strong agreement between DRS and MRU to assess UPJO. MRU static fluid has a high accuracy for assessment of renal system anatomy. Due to the lack of dangerous consequences of contrast materials, MRU can be the best option instead of DRS.

Stroke is the second most common cause of death and major cause of disability worldwide. The objective of this study is to identify the major risk factors and assess the awareness among the stroke survivors.

A prospective study was conducted at super specialty hospital, from December 2010 to July 2011. All the stroke patients of the age >25 years with either sex admitted in the hospital were included in the study. In order to assess the awareness among the stroke survivors, questionnaire established on the risk factors for stroke from the previously published studies.

A total of 100 patients with stroke or cerebrovascular accident were included in the study. Of 100 patients, 73% patients had ischemic stroke and 26% patients had hemorrhagic stroke. The mean age of the patients was 50 years and the incidence of stroke was predominant in males 73%, followed by females 27. It was observed that 70% of patients were hypertensives, 28% were diabetics, 27% were alcoholics, and 24% of patients had a habit of smoking, followed by others. The knowledge of the risk factors for stroke in stroke survivors was also very low, and the knowledge was varied among the subjects according to their level of educational status.

This study reveals that hypertension is the most common risk factor for stroke followed by diabetes, smoking, and dyslipidemia. The awareness of risk factor among stroke survivors was poor.

Lactoferrin (LF) is an iron-binding glycoprotein with antioxidant, anti-inflammatory and nitric oxide-dependent vasodilatory properties. In the present study, we investigated the protective and antioxidant effects of LF on H2O2-induced oxidative stress in human umbilical vein endothelial cells (HUVECs).

HUVECs were pretreated by (6.25–100 µg/ml) LF for 24 h and then exposed to 0.5 mM H2O2 for 2 h. Cell viability was assessed by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The intra- and extra-cellular hydroperoxides concentration and ferric reducing antioxidant power (FRAP) were determined in pretreated cells.

Pretreatment of HUVECs with LF at the concentrations of 25–100 µg/ml significantly reduced the cytotoxicity of H2O2 in a concentration-dependent manner using MTT assay. LF pretreatment at different concentration ranges also decreased the hydroperoxides level and augmented the FRAP value in both intra-and extra-cellular assay.

These findings revealed antioxidant and cytoprotective effects of LF against H2O2-induced oxidative stress in HUVECs. With regard to the beneficial vascular activity of LF, further investigations are suggested for understanding its clinical value in human endothelial dysfunction and prevention and/or treatment of CVDs.

Congenital adrenal hyperplasia (CAH) is a putative error of metabolism with autosomal recessive heredity pattern. The main manifestations of classic form of CAH are salt-wasting, dehydration and simple virilization in both sexes and ambiguous genitalia in female gender. 21-hyroxylase (CYP21A2) impairment with prevalence value of 1 in 10,000–15,000 live births is the most common etiology of CAH. Because of consanguineous marriages, the frequency of the CAH in Iran is very high. A wide range of mutations diversity exists in CYP21A2 gene and a large number of these mutations derived from a highly homologous pseudogene, CYP21A1P, through gene conversion. In addition, new mutations such as small and large deletion and point mutations can also result in enzyme deficiency. Various methods for mutation detection were performed. The main obstacle in molecular diagnosis of CAH is amplification of pseudogene during polymerase chain reaction of CYP21A2. All attempts focus on discrimination of pseudogene from gene; that is why, there is the majority of mutations on pseudogene, and if we have contamination with the pseudogene, the result will be unreliable. Here, we discuss this methods and advantage and disadvantage of those.
