Spontaneous tension pneumomediastinum with pneumothorax and subcutaneous emphysema as a complication of COVID-19 disease.

Recently spontaneous tension pneumomediastinum (STM), were reported as infrequent complications in coronavirus disease 2019 (COVID-19) patients but pneumothorax (PT), and subcutaneous emphysema (SE) are more frequently seen in COVID-19 patients. PT and SE may present after PTM in COVID-19. The aim of this presentation is to show the complications of STM in an Iranian patients with COVID-19 disease with PT and SE, who were hospitalized in Arya hospital, Rasht, Iran. For 3 months, we followed these patients and their condition was good. STM are uncommon complications in COVID-19 patients and were reported frequently in male patients. Early diagnosis and treatment could save the patients as these complications are related to poor prognosis and prolonged hospitalization. Patients with mild COVID-19 and mild pulmonary damage may have a favorable outcome.

Evaluation of the relationship between prestin serum biomarker and sensorineural hearing loss: a case-control study.

RESEARCH BACKGROUND AND AIM: There is not any routine serum biomarker for diagnosing hearing loss (HL). An inner ear-specific protein, prestin can be measured as a serum biochemical marker for HL diagnosis. The present study investigates, for the first time, the relationship between prestin serum levels and sensorineural HL (SNHL) in an Iranian population. MATERIALS AND METHODS: In this case-control study, 176 samples were examined in four groups including two control and two SNHL groups of 20-50 and ≥ 50 years with different severities of SNHL. Plasma prestin concentration was measured using Human Prestin (SLC26A5) ELISA Kit. Data analysis was conducted using SPSS v.23 with level of significance as 0.05. RESULTS: Groups with SNHL had higher prestin levels (Mean = 182.29, SD = 71.24) compared to the control groups (Mean = 122.50, SD = 57.1) (P < 0.001). Results of the multinomial logistic regression of relationship between prestin level and SNHL remained significant after controlling intervening variables (P < 0.001 and odds ratio = 1.017 and 95% CI OR: 1.01-1.024). Results of the ordinal logistic regression model revealed that prestin level was significantly associated with the degree of HL (P < 0.001 and Odds ratio = 1.009 and 95% CI and OR: 1.005-1.013), so that the likelihood of HL increased with the rise in prestin levels. The best cutoff point for the 20-50 group was the prestin content of 132.5 pg/ml (sensitivity: 75%, specificity: 70.05%), while for the group of ≥ 50 was as 130 pg/ml (sensitivity: 84.1%, specificity: 68.2%). CONCLUSIONS: Results of the present study revealed that prestin acts as a valuable biomarker for SNHL.

Evaluation of demographic and rare clinical characteristics of patients with thoracic carcinoid tumor in Razi and Aria Hospitals of Rasht during 2006-2016.

Introduction: Carcinoid tumors are malignant neoplasms of neuroendocrine cells. This study tended to evaluate the demographic and rare clinical characteristics of patients with thoracic carcinoid tumor during 2006-2016 at Razi and Aria Hospitals in Rasht. Materials and Methods: The present study was performed on records of 43 patients with lung carcinoid tumors referred to Razi and Aria Hospitals of Rasht during 2006-2016. Information on age, gender, rare clinical symptoms, smoking history, diagnosis tools, treatment, and outcome were analyzed. Results: Of 43 patients treated with definitive diagnosis of carcinoid tumor pathology, 31 patients had typic carcinoid tumor and 12 patients with atypic carcinoma (mean age 43.14 ± 15.16 years). The most common clinical symptom was cough and hemoptysis. Two cases presented with cushing syndrome, The most common diagnostic method in this study was simultaneous use of both CT scans and bronchoscopy. In 95.3% of cases, the tumor was pulmonary and in 4.7% of cases, it was extrapulmonary. Right lower lobe was the most common site of tumors and most of the surgeries used were lobectomy. Conclusion: This study showed that the most common clinical sign of thoracic carcinoid is cough and the tumor is pulmonary in 95.3% of cases. Right lower lobe was the most common site of tumors and most of the surgeries used were lobectomy. outcome was good.

Prevalence of anxiety and depression in Meniere's disease; a comparative analytical study.

BACKGROUND: Psychological problems are of most significant issues in patients with Meniere's disease (MD). This study aimed to reveal the frequency of anxiety and depression in MD patients compared to healthy individuals and patients with benign positional paroxysmal vertigo (BPPV) referred to a university hospital. METHODS: This case-control study was conducted on individuals between 18 and 65 years old assigned to three groups: the control, MD, and BPPV groups. The data collecting instruments included a demographic information form, along with Beck Anxiety Inventory (BAI) and Beck Depression Inventory-II (BDI-II) questionnaires. Data were analyzed using SPSS software v.23, and the significance level was considered as p < 0.05. RESULTS: A total of 177 participants enrolled. The average scores of anxiety and depression and the severity of anxiety and depression were higher in MD and BPPV groups than in the control group (P < 0.001). The average anxiety score and anxiety severity in the MD group was higher than in the BPPV group (P < 0.001). However, in the case of depression, only severity was higher in the MD group (P < 0.001), and the average depression score showed no significant difference between MD and BPPV groups. After controlling for underlying variables, the impacts of MD (P < 0.001; regression coefficient = 16.5) and also BPPV (P = 0.025; regression coefficient = 4.6) on anxiety were significant compared to the control group. CONCLUSION: Our results suggest that the prevalence of anxiety and depression is higher in MD and BPPV patients than the healthy people, and MD has a higher effect on the incidence of depression and anxiety compared to BPPV.

Evaluation of applying topical tranexamic acid to control septorhinoplasy - induced hemorrhage.

OBJECTIVES: Hemorrhagic events related to surgical field is a common disturbing complication which could worsen the outcomes of operation. This study aimed to evaluate how applying of topical tranexamic acid (TXA) could affect bleeding related to septorhinoplasty operation. MATERIAL AND METHODS: This double-blind controlled trial study finally evaluated 198 candidates for septorhinoplasty repair who were randomly allocated to two groups: TXA receivers (5 mg/kg) and control group (received 5 mg/kg of saline 0.9 %). Then cumulative volume of hemorrhage was calculated by adding total volume of suctioned blood and numbers of fully blood-filled surgical gauzes (15 mL in each). Additionally postoperative 24 h volume of hemorrhage was measured by counting number of bloody surgical gauzes. RESULTS: Of all participants, 90 % were female. The mean age was 26 ± 7 years. Total cumulative volume of hemorrhage during surgery was significantly diminished when topical TXA was applied (p < 0.0001). Additionally drier field of operation was illustrated postoperatively in patients received topical TXA (2 % & 28 % in TXA and saline 0.9 % receivers, respectively) (p < 0.001). CONCLUSION: Using topical TXA could decrease bleeding volume and make surgical field of septorhinoplasty drier either during surgery or postoperatively.
