The coronavirus disease 2019 (COVID-19) pandemic is the main challenges to public health systems worldwide now. Cancer patients are considered as a high risk group during the COVID-19 pandemic. Considering the evidence so far, cancer as underlying comorbidities might increase the risk of death in patients with COVID-19. Many cancer patients with increased risk of contracting COVID-19 than the general population regularly visit health facilities for treatment and disease surveillance. Thus, the COVID-19 pandemic has a profound impact on cancer care and treatment. Here, we attempted to summarize the current suggestions for handling of cancer patients during COVID-19 pandemic. We carried out a integrative literature review using several online bibliographies. A total of 113 papers were accessed for the time frame between October 05 2020 and October 10 2020. After screening of titles and full-texts, 10 publications were selected in this study. In this work some recommendations and guidelines that would help for management and treatment of cancer for the purpose of address the challenges during COVID-19 pandemic were collected. We hope that this collection recommendations and guidelines assist health care providers in management of individuals with underlying malignancy during the COVID-19 pandemic.

Recently, extracellular vesicles (EVs) are generating considerable interest in terms of their ability. EVs defined themselves as a route for intercellular communication between the origin cells and the recipient ones by transferring information. This paper investigates the influence of peripheral blood mononuclear cells derived EVs on proliferation and apoptosis of the chronic myelogenous leukemia cell line k562. Trypan blue staining was used to detect cell viability subsequently, metabolic activity was assessed by the MTT assay. Cell apoptosis and cell cycle progression were evaluated using flowcytometric assay after treatment of k562 cell line with MNC derived EVs .Our results showed that MNC-EVs have no inhibitory effect on k562 cell growth and proliferation. Our data did not reveal any significant variations in the case of enhancing k562 cell line growth following treatment with MNC derived EVs. It seems tumour-derived extracellular vesicles support tumour cells growth by communicating with each other through their extracellular vesicles.

Otomycosis is one of the overwhelming diseases both for patients and specialists with a high recurrence rate despite adequate and proper treatment. This study aims to investigate further the various types of fungi involved in otomycosis and test their susceptibility against common antifungals. In total, among candidiasis-suspected patients, 60 samples were incorporated into the study. PCR method was used for Candida species detection. Broth microdilution method of Clinical and Laboratory Standards Institute document M60 was applied to assess MIC values of rampant antifungals. We used SPSS software (version 16.0) for statistical analysis. In this survey, 20, 3, and 1 type of Candida albicans, Candida parapsilosis, and Candida glabrata were identified, respectively. All 20 C. albicans isolates were sensitive to amphotericin B (range 0.03-1 μg/ml), voriconazole, (0.03-1 μg/ml), and itraconazole (0.03-0.5 μg/ml.); moreover, one isolate was resistant to fluconazole. Two isolates out of three isolates of C. parapsilosis, were susceptible to all agents while the other one isolate was resistant to fluconazole. C. glabrata isolate was susceptible to all agents. In summary, the results conveyed the importance of clinicians remaining vigilant in diagnosing otomycosis due to its non-specific manifestations. To manage effectively otomycosis and avoid complications or recurrence, it is imperative to diagnose the condition at the earliest time, confirm its virulence through various tests, and identify antifungal susceptibility patterns. Despite this, relapse is often seen and achieving complete remission can prove to be a major hurdle in individuals who have had mastoidectomy and those with weakened immune systems.

Allergic rhinitis (AR) is a chronic inflammatory disease involving the nasal mucosa. Leukocytes recruitment to the inflammation sites is controlled by chemokines, cytokines, and adhesion molecules. Retinoic acid (RA), a vitamin A metabolite, plays an essential role in mucosal immunity and the production of inflammatory cytokines and chemokines. This study intended to evaluate the serum levels of RA, CCL17, CCL22, CCL28, and the mRNA expression levels of α4, β1, and β7 integrins in AR patients compared to healthy subjects. Peripheral blood was collected from 37 patients with AR and 30 age- and gender-matched healthy individuals. Serum levels of RA, CCL17, CCL22, and CCL28 were measured by the enzyme-linked immunosorbent assay (ELISA) technique, and the mRNA expression levels for α4, β1, and β7 integrins were assessed using the quantitative real-time PCR method. Our results showed that the serum levels of CCL22 and CCL28 chemokines are significantly higher in the AR group compared to the healthy controls (P<0.01). However, the gene expression of the β1 integrin in the AR group was significantly lower than that of the control group (P<0.001). Besides, there was a positive association between serum RA and CCL17 levels in patients (P<0.0001, r=0.6). In conclusion, increased serum levels of CCL22 and CCL28 chemokines, as well as decreased gene expression of β1 integrin in AR patients, may contribute to the pathogenesis and/or exacerbation of AR.

The goal of this study is to compare the brain connectivity patterns of autistic patients with those of children who are developing normally and analyzing quantitative electroencephalography in children with autism. The study included 50 children who were developing normally and 60 preschoolers who met the DSM-V criteria for autism spectrum disorder. Routine and quantitative electroencephalography were carried out on each subject, as well as a Childhood Autism Rating Scale. The electroencephalograms of 76.67% of autistic children were normal; 6.67% showed focal changes, and 16.67% showed generalized changes. While the alpha power in the central and temporal areas is significantly lower in autistic children, it is unchanged in the frontal and parieto-occipital regions. Children with autism have significantly higher absolute delta and theta band activity both globally and locally. It was shown that the total and regional absolute delta and theta power activity had a significant positive correlation with the disease severity score. Quantitative electroencephalography is a more effective tool for assessing and diagnosing children with autism spectrum disorder because it shows abnormalities in all autistic children. A correlation exists between the quantitative electroencephalography data and the disease severity score.

Sleep disorders are more common in diabetes mellitus (DM) cases rather than normal ones. In addition, this condition could be associated with diabetic retinopathy (DR) development with more inflammatory indices in circulation. In the present study, we have evaluated the association between DR and sleep quality. This cross-sectional study is a part of the second phase of the study of the elderly cohort of Amirkola City, which was conducted in 2015-2016 on all people aged 60 and higher. Of all diabetic cases, 44 cases had retinopathy and were selected as the case group. To compare two control groups, 135 diabetic patients without retinopathy and 135 people without diabetes were randomly selected. The presence and type of retinopathy were determined based on an eye physical examination by an ophthalmologist. In addition, sleep quality was evaluated based on the Pittsburgh Questionnaire. The obtained data were analyzed by ANOVA, t-test, and linear regression tests. In the present study, there was a significant difference in the score of the Pittsburgh questionnaire between people with DR (45.5±68.2) compared to diabetic people without retinopathy (76.5±48.2) and people without diabetes (95.4±36.2) (P=0.470), but diabetic people without retinopathy had significantly worse sleep quality than people without diabetes (P=0.019). Also, sleep quality in women with DR was worse than in men (P=014). In the linear regression analysis, it was observed that age, gender, diabetes, and history of depression significantly affect the sleep quality of the evaluated cases (P<0.05 for all). According to the results of the present study, DR does not negatively influence the quality of sleep, and DR is not related to sleep disorders.

Heterotopic pregnancy, a rare form of pregnancy, can occur Simultaneously intrauterine and extrauterine. This can be a life-threatening condition and can be easily overlooked if undiagnosed. The patient was a 27-year-old woman, gravid3, para1, live1 and abortion1, at 10 weeks and 1 day by last menstrual period who went to the emergency room complaining of pain in the lower abdomen form 3 days ago. Pelvic ultrasound revealed both live intrauterine and extrauterine pregnancy by gestational age based on the Crown-rump length diameter, 9 weeks and 3 days with moderate to severe hemoperitoneum. The heterotopic pregnancy diagnosis is difficult and requires a high index of suspicion.

Fibrous hamartoma of infancy is a rare benign tumor that’s mainly detected in the upper trunk. In this study authors report a 1-year-old case of perianal fibrous hamartoma which was successfully managed without need to orchidectomy or urethral manipulation.

Stroke has many different symptoms, isolated hand weakness is the rarest one. Even less common are concomitant radial nerve lesions and ischemic stroke that leads to isolated hand weakness. We report a patient with sudden onset of right wrist drop mimicking radial nerve palsy, found to be due to a acute cerebral infarct and radial nerve palsy in the same time. A well-taken history of the patient's illness and thorough clinical examination can differentiate stroke from peripheral neuropathy as the cause of hand weakness. Modern neuroradiological methods such as brain MSCT or MRI can quickly and reliably indicate the etiology of a neurological disease. In every patient who presents with isolated arm weakness, and for whom we are not sure whether it is a lesion of the central or peripheral nervous system, cerebral infarction must be included as a critical differential diagnosis because it can divert attention from sometimes harmful thrombolytic therapy.
