Wound healing is a complex process leading to regeneration of damaged skin tissue. Arnebia euchroma (AE) have many effective activities such as anti‑inflammatory, antimicrobial, antioxidative, and anti‑tumoral effects. The extract of AE has positive effects on burn wounds. This study is designed to investigate the healing effects of AE on excisional wounds in rats.

Thirty six rats with the age of 8 weeks divided into three groups. One group (E1) was treated with AE gel at a concentration of 10%. Control group (C1) received normal saline and the vehicle group (C2) was treated with carboxymethyl cellulose gel as the vehicle for 14 days. Stereological analysis was done to investigate the collagen bundle and hair follicale synthesis, vascularization, fibroblast proliferation. Pathological evaluation was also conducted.

In this study, pathological evaluation showed severe acute inflammation in C2 group, chronic and acute inflammation in C1 and also more wound contraction in E1 in comparison with other groups. There was a meaningful difference between E1 and C1 regarding fibroblast proliferation (P < 0.05).

Results of this study revealed the healing effect of AE on excisional wounds and recommend its administration after further clinical investigations.

Several common factors have been identified for smoking and depression. The The present study explores the relation of psychological and familial factors with depression, by student smoking behavior.

A total of 5500 middle‑ and high‑school students were selected in Isfahan province in 2010. A self‑administered questionnaire collected data on background characteristics, smoking status, depression, and risk factors. Univariate analysis multiple logistic regressions were conducted to compare between depressed and nondepressed people by adolescent smoking status. Odds ratios and the corresponding 95% confidence intervals (CIs) were reported.

Fathers lower education attainment was accompanied adolescents higher depression prevalence. Parental smoking and sibling smoking increased the depression likelihood by 1.41 (95% CI: 1.18, 1.68) and 1.43 folds (95% CI: 1.04–1.94) for never‑smokers. Positive attitude toward smoking increased the probability of depression by 1.18 among never‑smokers. Never‑smokers lacking refusal skill had 1.23 (1.03–1.47) higher chance of depression. A higher level of self‑efficacy related to lower chance of depression. Taking risky behavior, increased the depression likelihood by 1.56 (95% CI: 1.29–1.89) in never‑smokers, by 1.85 (95% CI: 1.37–2.44) in experimental smokers, and by 1.14 times (95% CI: 1.01–1.72) in current smokers. Family conflict increased depression chance by 2.25 times (95% CI: 1.89–2.66) in never‑smokers, by 1.95 (95% CI: 1.46–2.61) in experimental smokers, and by 2.06 times (95% CI: 1.38–3.08) in current smokers.

Targeting self‑efficacy level, risky behavior, and family conflict can drop the comorbidity of smoking and depression simultaneously. This may help public health practitioners and policymakers to develop common strategies in reducing adolescents smoking and depression comorbidity

This study aimed to compare the effects of the schema along with mindfulness‑based therapies in the psoriasis patients.

This semi‑experimental study with post‑ and pre‑tests was conducted on the psoriasis patients in the Dermatology Clinic of the Isfahan Alzahra Hospital, Iran using the convenience sampling in 2014. The patients had a low general health score. The experimental groups included two treatment groups of schema‑based (n = 8) and mindfulness (n = 8). Both groups received eight 90‑min sessions therapy once a week; they were compared with 8 patients in the control group. To evaluate the psoriasis patients’ maladaptive schema, Young schema questionnaire was used. Data were analyzed through the covariance analysis test.

There was a significant difference between the schema‑based therapy and mindfulness groups with the control group. There was also a significant difference between the schema‑based therapy groups consisting of the defeated schema, dependence/incompetence schema, devotion schema, stubbornly criteria schema, merit schema, restraint/inadequate self‑discipline schema, and the control group. Moreover, a significant difference existed between the maladaptive schema of mindfulness therapy group and the controls. There was a significant difference concerning the improvement of the psychopathologic symptoms between the mindfulness therapy group and the control group.

This study showed similar effects of both the schema and mindfulness‑based therapies on the maladaptive schemas in improving the psoriasis patients with the psychopathologic symptoms.

 Peritonitis and exit site (ES) infection are two main complications of peritoneal dialysis. There are some controversies regard to preventive strategies for ES care. In this study we compared peritonitis and ES infection rates in patients with and without dressing.

This historical cohort study carried out on 72 patients under continuous ambulatory peritoneal dialysis treatment, 54 with dressing versus 18 patients without dressing, followed from October 1, 2010 to March 31, 2011 for peritonitis and ES infection.

A total of 17 episodes of ES infection occurred in 12 patients in dressing group, but no case was seen in no‑dressing group (P = 0.02). Twenty‑one episodes of peritonitis occurred in 15 patients in both groups (one episode every 20.6 patient‑months). In no‑dressing group two episodes occurred in only one patient (one episode every 54 patient‑months), and in dressing group, 19 episode in 14 patients (one episode every 17.1 patient‑months) (P = 0.03). Peritonitis was significantly more frequent in male versus female in overall patients (38% vs. 14%, P = 0.025) and in dressing group (52% vs. 15%, P = 0.003). In dressing group, peritonitis was more frequent in diabetics versus non‑diabetics (48% vs. 11%, P = 0.01). Odds ratio for developing peritonitis was 9.4 in dressing group (95% confidence interval [CI] =1.05 − 84.4; P = 0.045), and 4.4 in men (95% CI = 1.26 − 15.19; P = 0.02).

In this study, chronic ES care without dressing was associated with lower risk of peritonitis and ES infection.

Colorectal cancer (CRC) is one of the most commonly diagnosed cancers worldwide. It is also known as the second leading cause of deaths as the early stage detection is not yet available by current methods. So identification of biomarkers can also be functional in early diagnosis and prognosis.

We examined sera from 60 CRC patients of different stages as a source of auto‑antibody as well as two human CRC cell lines with different invasive capacities (SW48 and SW1116) as the source of antigens. The pattern of immune reactivity in immuneblotting tests between mentioned cell lines and CRC patients’ sera were evaluated by ImageJ software.

The Immune reactivity pattern of two cell lines (SW48 and SW1116) with CRC patients’ sera were different in band intensities and the most immune reactivity intensity was observed in SW48 cell lysate with sera from Stage III CRC patients.

Due to the humoral immune response, sera from Stage III CRC patients contained autoantibodies that demonstrated higher immune reactivity. Moreover, SW48 cell line with high aggressive behavior reacted to CRC patients’ sera with greater intensity compared with less aggressive behavior cell line (SW1116). Therefore, it is required to use other techniques such as two‑dimensional electrophoresis and mass spectrometry

To evaluate the correlation of magnetic resonance imaging (MRI) features of breast lesions of Breast Imaging Reporting and Database System (BI‑RADS) category 4 with histopathologic results.

In a prospective study between December 2013 and April 2015, patients with suspicious mammographic and/or ultrasound findings referred for Breast MRI were evaluated. Patients with lesions of BI‑RADS category 4 were enrolled with a written informed consent. In each patient, mass lesion (ML) or nonmass lesion (NML) was determined, and different characteristics of the lesions were recorded. A follow‑up program was taken with mean 3–12 months. Patients who underwent core needle biopsy or open biopsy were summoned.

Seventy‑eight females aged 24–67 years (mean 43.1 ± 8.8) met the inclusion criteria and had adequate samples for histopathologic study. Twenty‑nine (37.2%) patients had ML and 49 (62.8%) patients had NML. Tissue sampling in 63 (80.7%) patients was through core needle biopsy and in 15 (19.2%) patients through surgery. A wide spectrum of benign and malignant pathologic diagnoses was seen. In statistical analysis, none of the MRI features has a significant correlation with any specific histopathologic diagnosis (P = 0.185). However, the relation between the MRI category (ML or NML) and pathology results was significant at level of 0.1 (P = 0.06).

This study showed that a wide spectrum of histopathologic results is seen in BI‑RADS category 4. However, in this sample volume, none of the MRI features in this BI‑RADS category has a significant correlation with any specific histopathologic diagnosis.

Mastitis is an inflammatory disorder in breast tissues due to bacterial factors, mycobacterial infections or autoimmune diseases. Idiopathic granulomatous mastitis (IGM) is a form of mastitis which may be affected by systematic diseases such as sarcoidosis, and infectious causes such as mycobacterium and fungus. This study evaluates the efficacy of medical therapy with a combination of corticosteroid and Azithromycin in patients with IGM.

This study is a clinical trial research carried out in Alzahra Hospital (Isfahan, Iran) in 2013 on granulomatous mastitis patients. It was administered 250 mg of Azithromycin per 12 hour and 60 mg of Prednisolone per day within 2 weeks. Next, they took 40 mg/day within 8 weeks, and this dosage was tapered during 6 months and the patients clinically and radiologically followed up. The studied patients were examined within 1 week, 2 weeks, 1 month, 3 months, and 6 months, from the beginning of treatment.

This study investigated granulomatous mastitis patients in Alzahra hospital in 2013. The mean age of these patients was 33.6 ± 8.9, and their age range was 18–56 years old. Among 26 studied patients, 24 persons (92.3%) according to follow‑up the patients by physical examination and sonography responded to treatment of corticosteroid and Azithromycin. The remaining (7.7%) underwent surgery. Treatment periods in case of drug use were respectively, 8.5 ± 0.71 months.

Treatment with corticosteroid and Azithromycin is an effective and appropriate treatment for IGM.
