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 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.

The effects of functional endoscopic sinus surgery on chronic obstructive pulmonary disease (COPD) and asthma: A comparative study.

PURPOSE: Chronic Rhinosinusitis (CRS) can be accompanied by asthma and, rarely by chronic obstructive pulmonary disease (COPD). Functional endoscopic sinus surgery (FESS) is the most common surgical approach for CRS which also improves asthma symptoms, but little is known about its effects on COPD. This study investigates the effects of FESS on COPD and asthma symptoms in CRS patients referred to a university hospital in northern Iran. MATERIALS AND METHODS: In a prospective study, patients with COPD or asthma and CRS who were candidates for FESS underwent endoscopic examination, spirometry, and evaluation of symptoms of CRS, COPD, and asthma before, and 2 and 6 months after FESS. Statistical analyzes were performed using SPSS software version 21 and the level of significance was considered as P < 0.05. RESULTS: Eighty-two CRS patients (45 with asthma/ mean age: 49.24 ± 12.75 years and 37 patients with COPD/ mean age: 61.43 ± 6.93 years) enrolled. In asthmatic patients, the mean FEV1 and FVC, and ACT (Asthma Control Test) score increased significantly after FESS (P < 0.001). In COPD cases, spirometry indices decreased, but CAT (COPD Assessment Test) score improved significantly (from 15.70 to 32.11) after FESS (P < 0.001). The mean SNOT score in both groups was significantly reduced. CONCLUSIONS: In CRS patients with COPD, FESS improves the condition of SNOT-22 and CAT, although does not increase spirometry parameters. In asthmatic patients, FESS improves pulmonary function and asthma symptoms. So both patient groups (i.e. CRS with COPD and with asthma) will benefit from FESS.

Evaluation of the Relationship Between Primary Spontaneous Pneumothorax and Exercise and Return to Previous Activities in Patients Referring to Hospitals of Rasht during 2015-2017.

BACKGROUND: The most common cause of primary spontaneous pneumothorax (PSP) is subpleural bleb apical rupture. Little is known about the relationship between PSP and exercise and return to exercise the time. In this study, we tend to investigate the relationship between training and PSP and time of return to exercise and previous activities. METHOD: This study was designed as a case series and the sample size included all patients diagnosed with PSP in Razi and Poursina and Aria hospitals of Rasht during 2015-2017 based on inclusion criteria. Variables were analyzed using Fisher's exact test, Chi-square, Mann Whitney U and t-test (p<0.05). RESULTS: The most common treatment type in patients was transaxillary thoracotomy with pleurodesis with iodine (TTP) in 58.2% and tube thoracostomy and pleurodesis in 41.7%, which was not statistically significant between athletes and non-athletes (p=0.806). Athletes who underwent TTP after four weeks and those treated with tube thoracostomy and pleurodesis after 8-12 weeks were advised to return to their previous activity. Of athletes, 9.5% had a recurrence; of non-athletes, 9.8% had a recurrence. Of athletes, 4.8% did not tolerate returning to their last activity; of non-athletes, 7.3% did not tolerate returning to their previous activity regardless of treatment, and this difference was not significant. CONCLUSION: Our study showed no significant difference between clinical manifestations and image findings and the frequency of treatment and complications in both athlete and non-athlete patients. There is no increase in recurrence and intolerance at the time recommended for return to previous activity.

Multicystic dysplastic kidney in association with congenital ichthyosiform erythroderma.

Multicystic dysplastic kidney is a noninherited congenital disease. Association of this disease with abnormalities of various organs is common. We, however, report a rare case of multicystic dysplastic kidney associated with congenital ichthyosiform erythroderma in an infant. Different developmental origins of the skin and the kidney can explain the scarcity of concurrent congenital skin and kidney abnormalities. Nonetheless, the development of both organs depends on mesenchyme-epithelial interactions for inductive signaling. It seems defects in the production of signaling molecules can explain such an association.
