Background: Cervical cavernous hemangioma is an extremely rare, benign lesions, and only a few cases are reported. Cervical cavernous Hemangiomas are characterized by an increase in the number of normal and abnormal veins. The majority of these lesions are superficial, often found in the head and neck area, but may also occur in the inner parts of the body. The occurrence of these lesions in the female reproductive tract, especially the the cervix is extremely rare. This disease should be considered as a differential diagnosis of abnormal uterine bleeding because of the low prevalence and importance of the diagnosis of this uncommon disease. The majority of cervical cavernous hemangiomas have been reported in women of childbearing age. Besides, although most lesions are symptomatic (mostly bleeding), diagnosis is often unlikely. They may cause abnormal vaginal bleeding in the form of menometrorrhagia and postcoital spotting. To date, fewer than 55 cases have been reported. This study aimed to report a rare case of cervical cavernous hemangioma.
Case Report: The patient was a 24-year-old woman who had referred to the outpatient clinic of Ghaem Hospital in September 2016 due to prolonged post coital bleeding after intercourse. At the time of the pelvic examination, posterior lip of cervix was very vascular and there was black color that had extend to the vagina. The patient underwent colposcopy. Following colposcopy, due to severe cervical bleeding, the vagina packed. The patient's bleeding was controlled with the pack after 24 hours. Cervical pathology revealed a cavernous hemangioma.

Background: Because deep vein thrombosis (DVT) is one of the most common problems in the intensive care unit, it may lead to complecating the patient's general condition. This study aimed to investigate the predictive factors of DVT in patients admitted to the intensive care unit (ICU) of Amin hospital in Isfahan.
Methods: In this retrospective study, all the records of patients admitted to the ICU ward of Amin Hospital located in Esfahan, from April 2015 to March 2018, were investigated and from all patients with DVT, 20 records were extracted and 40 cases of patients without DVT were also randomly selected. Information such as age, sex, Wells score, Apache score, nutritional status, clinical parameters, cause of hospitalization, length of stay, ICU induced disease and treatment were extracted from these records and compared between both groups with and without DVT.

Conclusion: In the general intensive care unit, the incidence of deep vein thrombosis was higher in internal ward patients. Pneumonia was the most common disease associated with deep vein thrombosis and the risk of deep vein thrombosis was higher in the anemic patient. Patients with upper limited normal levels of potassium were less likely to develop deep vein thrombosis. It seems that potassium in the upper limit of normal reference can play a protective role against deep vein thrombosis. Further studies with larger sample sizes are suggested.

Background: At present, in nuclear medicine to calculate the cumulative activity of various organs, different techniques are being used to correct the background radiations in the conjugate view method. Each of these techniques considers the effect and weight of background radiations to a different extent. These background radiations can cause errors in cumulative activity calculations. The purpose of this study was to evaluate and compare different techniques of correcting background radiations to each other in calculating kidney cumulative activity during the nuclear scan of the bladder in children.
Methods: This study was Cross-sectional and performed for patients who were referred to Isfahan Shahid Chamran Hospital between December 2019 and June 2020. In this study using Foley, 1 mCi of TC-DTPA radio-pharmaceutical that was diluted with normal saline was injected into the patient's bladder, then images recorded by gamma cameras were extracted at 2, 5, 10, and 20 minutes, Finally with ROI drawing around kidney with having vesicoureteral reflux, Cumulative renal activity was calculated with four correcting background radiations techniques such as without correction of background radiation, conventional method, Buijs method, and Kojima method Eventually, the data was Eventually, the data was compared to each other to determine how much weight each of these techniques consider for background radiations.

Background: Nicolau syndrome is a rare condition that happens after intramuscular injection. All the intramuscular injections may have mild to moderate complications such as pain, focal abscess, nerve complication and anaphylactic reactions. Among these complications, wide necrosis of the skin like Nicolau syndrome happens very rarely. In this condition, Patients typically report acute, intense pain, immediately after drug injection and it is followed by an erythematous macular evolving after 24 hours into a livedoid violaceous patch with dendritic extensions. The study has been reported a case report of a 6-month-old infant who suffered from Nicolau syndrome after the injection of pentavalent vaccine.
Methods: A 6-month-old girl infant without a history of any disease was referred to the emergency department with the signs of erythema, edema and purple like discoloration in the vaccine injection site at the left tight, after vaccination. One hour after admission, in the lower limb severe edema along with an extension of a dark red to purple discoloration happened on different parts of foot and after 5 days they turned necrotic. The infant suffered from Nicolau syndrome after the injection of the pentavalent vaccine.

Conclusion: Results of this study showcased the importance of TNF-α in disease progression and treatment failure. Further future studies regarding this relationship can provide vital information in AIDS treatment research.

Background: Asthma is a chronic inflammatory disease of the airways. Various tests and questionnaires are designed to monitor the severity of asthma and help the therapist and the health system prescribe the best treatment to control it. This study was designed to compare two methods Asthma Control Questionnaires (ACQ) and Asthma Control test-child (ACT-CHILD) in children with asthma.
Methods: This descriptive cross-sectional study was conducted on 92 children with asthma referred to the Taleghani hospital, Gorgan, in 2022-2023. Patients were in a range of age 4-16 years. Asthma control was evaluated and compared by two methods ACT-CHILD and ACQ. ACT-CHILD included one version for 4-11-year patients completed by their parents and another one for 12-16 –year patients completed by the patients. The clinical symptoms, age, gender and the parents' records related to asthma were completed during the clinical interview. Data was analyzed using Chi-square and Spearman correlation tests. The degree of agreement between two questionnaires was determined using the Kappa coefficient.

Results: 84 children aged 4-11 years (91.3%) and 8 children aged 12-16 years (8.7%) were included in the study. According to the ACT-CHILD, 40.2% of children (n=37) had controlled asthma, 44.6% (n=41) had partially controlled asthma, and 15.2% (n=14) had uncontrolled asthma. Based on the ACQ, controlled asthma was observed in 18.5% (n=17), partially controlled asthma in 35.8% (n=33), and uncontrolled asthma in 45.7% (n=42) of children. Asthma control results based on two questionnaires were significantly different from each other (P<0.001). The agreement between the ACT-CHILD and ACQ methods in evaluating children's asthma was at a weak level (P=0.014, κ=0.157), however, a significant negative correlation was observed between the scores of the ACT-CHILD and ACQ questionnaires (r=-0.588, P>0.001) which after categorizing based on age group, this correlation was confirmed only in children aged 4-11 years (r=-0.627, P>0.001). Conclusion: Our findings showed that there is a poor agreement between ACT-CHILD and ACQ results in the assessment of asthma control. Further studies are recommended.

Background: Considering the high prevalence of breast masses and the importance of screening and follow-up for malignancies in women, and since age and hormonal changes during menopause play a role in determining the type of pathology and prognosis of the masses, the purpose of this study is to determine the relationship between menopause and mass pathology.
Methods: This was a cross-sectional-analytical study that was conducted in order to investigate the types of pathology of breast masses and their relationship with the age of menopause in women referred to Shahid Beheshti Hospital in Qom between April 2013 and April 2019. The inclusion criteria include: having sufficient file information and having a contact number to complete personal information, no history of cancer in other parts of the body and simultaneous malignancies, and the exclusion criteria also include: samples that were taken by cellular aspiration sampling, There were women who had a history of first-degree breast malignancy and were previously diagnosed with breast cancer and there was a possibility that the new mass under study was metastatic. Finally, the patients' information was extracted from the files and recorded in pre-prepared checklists. And the supplementary information of the incomplete files was asked and completed using the contact information of the patients. After collecting the information, using SPSS software version 26 and with chi-square and t-test statistical tests and considering the significance level of 0.05 the data was analyzed.

Results: He prevalence of malignancy in postmenopausal women was higher than in premenopausal women. Also, a significant difference was found between tumor size, the presence or absence of metastasis, and menopause (P<0.05), but no significant difference was found between tumor location and menopause (P>0.05). Conclusion: Breast malignancies (invasive ductal carcinoma, invasive mixed carcinoma, mucinous, medullary, and papillary carcinoma) were more common in postmenopausal women than non-menopausal women. In both groups, ductal dilatation and chronic inflammation were the most benign findings, and fibroadenoma was found at a much lower rate in menopausal women than in non-menopausal.

Background: Understanding the complex processes of the immune system in dealing with the covid-19 infection, which is probably related to polymorphisms in cytokine and chemokine genes, can explain the pro-inflammatory condition of patients. Accordingly, in the present study, the correlation between the frequency of single nucleotide polymorphisms in the pro-inflammatory IFNAR2 gene and the severity of the disease of COVID-19 was investigated.
Methods: This research was reviewed by the ethics committee of the Pasteur Institute of Iran and was approved by this committee with the ethics code IR.PII.REC.1400.042. and continued from December 2021 to November 2022. This study was conducted on 954 patients with COVID-19, who were divided into two groups: those who recovered and those who died. COVID-19 infection in all 954 volunteers has been confirmed through rtReal Time-PCR of oropharyngeal or nasopharyngeal swabs.After taking blood samples from patients and extracting DNA, IFNAR2 gene was amplified using specific primers. Then RFPL method and Cac8I restriction enzyme were used to investigate rs2236757 polymorphisms in IFNAR2 gene. Genotype of people was determined according to the pattern of formed bands. The results were statistically analyzed using SPSS software.

Results: Calculation of genotypic frequency of rs2236757 polymorphism in IFNAR2 gene showed that in general 21% of cases had AA genotype, 47% GA genotype and 32% GG genotype. The allelic frequency of this polymorphism showed that 56% of cases had G allele and 44% had A allele. In investigating the correlation of rs2236757 polymorphism in IFNAR2 gene with the severity of the disease of Covid-19, the OR value for the GG genotype was equal to 1, which indicates the absence of the role of this polymorphism in the severity of the disease. On the other hand, A allele was significantly more in recovered people than in deceased people, and the value of OR<1 also confirmed this issue. Conclusion: The results showed that rs2236757 in the IFNAR2 gene is related to the reduction of disease severity, which indicates the important role of genes related to inflammatory responses, as well as the role of genetic variants of these genes in the severity of COVID-19.

Results: Among the 975 articles in the initial search, 525 articles are due to the repetition of the title and 442 articles due to other reasons such as not assigning humor therapy in breast cancer, not implementing the joke and laughter intervention program, the language of the article not being related to English or Farsi, and not Conducting clinical trials were excluded, and finally eight articles that scored higher than 3 were included in the systematic review. The results of the studies showed that laughter therapy had an effective role in improving the quality of life, improving various aspects of mental health, reducing negative emotions such as anxiety, stress, depression, pain intensity, fatigue and strengthening positive emotions such as self-esteem, mood. while There has been a non-significant decrease in the dermatitis caused by radiotherapy and the activity of immune cells and the serum level of cortisol. Conclusion: Considering the positive effect of laughter therapy in reducing the negative emotions of patients, it is recommended that nursing managers and psychologists use this easy, fun, uncomplicated and accessible intervention to improve the physical, mental and emotional health of women with breast cancer.

Background: Although the respiratory system is the main element involved in the disease of COVID-19, nevertheless, there are reports of the involvement of other organs and their lesser symptoms. This study was conducted with the aim of investigating the frequency of gastrointestinal symptoms in patients with COVID-19.
Methods: This cross-sectional descriptive study was conducted on all patients diagnosed with COVID-19 hospitalized in Imam Khomeini Hospital from April to September 2021 by census method. The data was collected using a checklist that included demographic information. After the data was collected, it was entered into SPSS software, version 18 (IBM SPSS, Armonk, NY, USA) and analyzed with the help of descriptive statistics.

Results: In this study, the results showed that out of 2580 hospitalized patients, 54% were women and 46% were men. And the average age of the patients was 58.67±17.68. The highest frequency of people was in the age range of 40-59 years (925 people). 64% of patients had at least one gastrointestinal symptom, Each of the symptoms had a different prevalence, Anorexia 40% with a preference for men (57%) and the highest frequency in the age range of 40-59 years (430 people), gastrointestinal bleeding 10% with a preference for men (80%), And the highest frequency in the age range of 60-79 years (112 people), abdominal pain 8% with preference for women (65%) with preference for frequency in the age range of 40-59 years (65 people), vomiting 3% with preference for women (51%) with abundance in the age range of 80-99 years (58 people), diarrhea 1.5% with preference in men (51%) with abundance in the age range of 60-79 years (18 people) and constipation in 0.2% with preference Women (67%), all of whom were over 60 years old. Conclusion: The findings of this study showed that the COVID-19 disease can not only involve the respiratory system but also the digestive system in the course or beginning of the disease.
