RESUMO
INTRODUCTION: Tracheostomy decannulation is a routine procedure in airway management. There is no standard decannulation method; however, the two commonly practiced approaches are tracheostomy downsizing and intermittent capping, which are both accompanied by multiple visits to the clinic and increase patient discomfort. Herein, we explore fiberoptic bronchoscopy application in a novel single-stage decannulation protocol. METHODS: We conducted a retrospective study on tracheostomy patients eligible for decannulation. Fiberoptic bronchoscopy was performed on patients with spontaneous ventilation for ≥48 h, age ≥18, hemodynamic stability, normal chest X-ray, adequate swallowing, effective cough, adequate consciousness, patent speaking valve, and absent history of recurrent aspiration. Tracheostomy removal occurred after evaluating the airway and ruling out tracheomalacia, tracheitis with stenosis, obstructive granulation tissue, and moderate-to-severe stenosis. We documented patients' demographic and clinical information, along with details of their post-decannulation course. RESULTS: Out of 58 patients admitted for tracheostomy removal, we excluded six patients (10.3%) from the study because, despite clinical indications for successful weaning, they exhibited abnormalities that interrupted the decannulation process. Of the remaining 52 patients, 50 (96.1%) were successfully weaned off, while two needed reinsertion during their hospital course. Bronchoscopy findings were unremarkable in 33 (63.5%) patients, and the most frequently observed abnormalities were paucity of vocal cord movement in 5 (9.6%) patients and granulation tissue formation in 5 (9.6%) patients. No further airway management was necessary after discharge. CONCLUSIONS: Our study introduces the innovative approach of single-stage bronchoscopic decannulation as a potentially beneficial tool for immediate decannulation. Based on our experience, we achieved a relatively satisfactory outcome following single-stage tracheostomy decannulation with bronchoscopy. The approach shows promise in providing valuable airway insights and predicting possible decannulation failures. Further research is needed to evaluate its impact on stress reduction for patients and surgeons, its superiority compared to traditional techniques, its long-term effects on healthcare, and its potential cost-effectiveness.
RESUMO
BACKGROUND: Since Shiraz Transplant Center is one of the major transplant centers in Iran and the Middle East, this study was conducted to evaluate outcomes of the applied policies on COVID-19 detection and management. METHODS: During 4 months from March to June 2020, patient's data diagnosed with the impression of COVID-19 were extracted and evaluated based on demographic and clinical features, along with the length of hospital stay and expenses. RESULTS: Our data demonstrated that a total of 190 individuals, with a median age of 58, were diagnosed with COVID-19 during the mentioned period. Among these, 21 patients had a positive PCR test and 56 patients had clinical symptoms in favor of COVID-19. Also, 113 (59%) patients were classified as mild based on clinical evidence and were treated on an outpatient basis. Furthermore, 81 out of 450 cases (18%) of the healthcare workers at our center had either PCR of clinical features in favor of COVID-19. The mortality rate of our study was 11% and diabetes mellitus, hypertension were considered risk factors for obtaining COVID-19 infection. The direct cost of treatment and management of patients with COVID-19 amounted to 2,067,730,919 IRR, which considering the 77 patients admitted to Gary Zone per capita direct cost of treatment each patient was 26,853,648 IRR. CONCLUSION: We demonstrated that the COVID-19 pandemic had a noticeable influence on our transplant center in aspects of delaying surgery and increased hospital costs and burden. However, by implanting proper protocols, we were able to was able to provide early detection for COVID-19 and apply necessary treatment and prevention protocols to safeguard the patients under its coverage, especially immunocompromised patients.
RESUMO
Cystic echinococcosis (CE) is one of the most important helminthic diseases in the world with different genotypes distribution. The application of specific genotype antigens together with sera from patients with specific cyst genotypes have not been reported, so far. The present study aimed to apply and evaluate native AgB from Echinococcus granulosus sensu stricto (Eg) and Echinococcus canadensis (Ec) alone or mixture for serodiagnosis of human G1-G3 and G6/G7 genotypes cystic echinococcosis sera, using ELISA and Western blotting. A total of 47 human sera along with 47 human CE cysts were collected. CE genotypes were determined. Native AgB were prepared from E. granulosus s.s and E. canadensis genotypes. ELISA and Western blot were performed on human specific G1-G3 and G6/G7 genotypes sera. Species specific native AgB were used alone or mixed. The sensitivity of ELISA using alone and mixed 1Eg-1Ec, 1Eg-2Ec, and 2Eg-1Ec of native AgB from E. granulosus s.s and E. canadensis genotypes for human G1-G3 sera were 92.10, 89.47, 97.37, 100, and 100%, respectively; while using AgBs, alone and mixed for human G6/G7 sera were 100%. The sensitivity of Western blotting using native AgB of E. granulosus s.s and E. canadensis genotypes alone and mixed 2Eg-1Ec were 78.95% and 100% for human G1-G3 and G6/G7 genotypes sera, respectively. The mixture of AgB from Echinoccus granulosus sensu stricto and Echinococcus canadensis genotypes increased ELISA sensitivity for the diagnosis of human CE. Preparation and application of native AgB from specific and prevalent genotypes of CE in endemic regions is recommended.

INTRODUCTION: Esophageal perforation is a surgical emergency with a high rate of morbidity and mortality. Its poor prognosis is mainly associated with previous patient-specific comorbidities and a lack of timely diagnosis and treatment. The objective of this study was to investigate the etiological factors and different surgical methods of treatment with consideration of mortality rate and comorbidities. METHOD: The present cross-sectional study was conducted on patients who underwent surgical intervention due to esophageal injury from 2002 to 2019 (18 years). Demographic and clinical characteristics along with performed surgical interventions were evaluated accordingly. RESULTS: In this study, 69 patients with a mean age of 38.8 years were evaluated, of which 45 (65.2%) cases were men. In terms of location of the perforation, the thoracic portion of the esophagus followed by the cervical and abdominal esophagus were more frequently injured with a rate of 32 (46.4%), 30 (43.5%), and 19 (27.5%) cases, respectively. Accordingly, foreign body ingestion followed by penetrating injuries were the most common causative agents leading to esophageal perforation. CONCLUSION: Obtaining the desired results from the treatment of this condition depends on factors such as patients' previous comorbidities, cause of the rupture, the location of the esophageal damage, and delay in the start of treatment. Since there is no single gold standard treatment strategy, each patient should be individually evaluated.

BACKGROUND: Tracheal resection and anastomosis surgery is a safe operation and is used to treat various benign and malignant diseases of the trachea. However, tracheal stenosis is among the main anastomotic complications following this procedure. Surgeons use both the continuous and the interrupted suture techniques for tracheal anastomosis, but contradicting results in each technique's complications have been reported in various studies. In this study, we aimed to compare the outcome of these two different suture techniques and a relevant literature review. METHODS: Surgical records during a period of 15 years (2005-2019) were screened for tracheal reconstruction surgery in affiliated hospitals of Shiraz University of Medical Sciences, Shiraz, Iran. A total of 82 patients were evaluated based on surgical and suture features, along with their follow-up bronchoscopy for anastomotic complications. RESULTS: Post-operational subclinical restenosis occurred in 8 (15.3%) out of 52 and 10 (33.3%) of 30 patients who underwent continuous and interrupted suturing techniques, respectively. Also, 6 (20%) patients in the interrupted group developed symptomatic restenosis, while in the continuous group, only one patient was clinically symptomatic. The patients with continuous suture technique had a shorter surgery time than patients whose interrupted technique was used (P < 0.001). CONCLUSIONS: Based on our results, we conclude that restenosis is significantly reduced when the continuous technique is applied for tracheal anastomosis; However, the results are contradicting in relevant literature and due to the retrospective nature of our study, further human studies and clinical trials are warranted.

BACKGROUND: The management of COVID-19 in organ transplant recipients is among the most imperative, yet less discussed, issues based on their immunocompromised status along with their vast post-transplant medication regimens. No conclusive study has been published to evaluate proper anti-viral and immunomodulator medications effect in treating COVID-19 patients to this date. METHOD: This retrospective study was conducted in Shiraz Transplant Hospital, Iran from March 2020 to May 2021 and included COVID-19 diagnosed patients based on SARS-CoV-2 RT-PCR positive test who had been hospitalized for at least 48 h before enrolling in the study. Clinical and demographic information of patients, along with their treatment course and the medication used were evaluated and analyzed using multiple regression analysis. RESULTS: A total of 245 patients with a mean age of 49.59 years were included with a mortality rate of 8.16%. The administration of Remdesivir as an anti-viral drug (P value < 0.001) and Tocilizumab as an immunomodulator drug (P value < 0.001) could reduce the hospitalization period in the hospital and the intensive care unit, as well as the mortality rates significantly. Meanwhile, the patients treated with Lopinavir/Ritonavir experienced a lower chance of survival (OR < 1, P value = 0.04). No significant difference was observed between various therapeutic regimens in clinical complications such as bacterial coinfections, cardiovascular and gastrointestinal adverse reactions, and liver or kidney dysfunctions. CONCLUSION: The administration of Remdesivir as an anti-viral and Tocilizumab as an immunomodulatory drug in solid-organ transplant recipients could be promising treatments of choice to manage COVID-19.

BACKGROUND: Despite profound advances in conservative management of esophageal perforation, patients' selection for this type of treatment requires expert clinical judgment. Surgical intervention has been historically introduced as the optimal management in multifocal ruptures. CASE PRESENTATION: Here, we presented a 30-year-old man whose barium esophagogram confirmed bilateral perforations in the lower third of the esophagus contained in the mediastinum, and contrast drained back into the esophageal lumen. Concerning available contrast imaging studies and thoracic surgeons, conservative non-operative management was considered despite pneumomediastinum, a mild right-sided pleural effusion, and minimal leukocytosis. The patient was followed up for two months without any complications. CONCLUSIONS: Bilateral and multifocal esophageal perforations can be managed conservatively provided that the leaks are confined to the mediastinum and drain back to the esophageal lumen, and other criteria for conservative management are met.

BACKGROUND: Intrapulmonary teratoma (IPT) is a rare type of extra gonadal teratoma which often presents with non-specific symptoms and can be misdiagnosed as other diseases. Here we report a patient with IPT which was initially misdiagnosed as lung hydatid cyst versus abscess. CASE PRESENTATION: We report an intrapulmonary teratoma in a 27-year-old female presenting with persistent chest pain and dyspnea since a few years prior to her admission with associated symptoms of cough and fever. Chest x-ray only showed left side massive pleural effusion and computed tomography scan of the lungs was suggestive of hydatid cyst or a lung abscess. She underwent lobectomy and postoperative histopathological study revealed IPT as the final diagnosis. CONCLUSION: Due to the non-specific symptoms and rarity, IPT can be easily misdiagnosed at first. It is essential that physicians take into account the possibility of IPT when approaching a new case of lung mass.

Pectus excavatum is the most common congenital deformity of the chest wall. The most frequently used techniques include Ravitch (costochondral resection) and Nuss (minimally invasive pectus repair of pectus excavatum [MIRPE]). The Nuss technique includes using temporary metallic bars without costochondral resection to correct the chest wall deformity. Modified MIRPE can be learned easily and performed safely with few complications. There are no reports of successful MIRPE in Iran, although the Ravitch technique is well known. In the present study, we report the first Iranian experience with the modified Nuss procedure in 5 patients with pectus excavatum (age range=13-48 y). All the patients suffered from low self-esteem, and one of them complained of low exercise capacity and occasional chest pain. With single-lung ventilation and sternal elevation, an introducer was entered into the right thoracic cavity and retrosternal tunneling was performed under thoracoscopic vision. The introducer was passed to the left thoracic cavity and exited on the left thoracic wall. A titanium plate bar was implanted and fixed with stabilizers. There were no cases of mortality, and all the patients were discharged in good conditions within 2 weeks. Postoperative complications consisted of 1 case of pneumothorax and 2 cases of fixed bar protrusion. The present case series indicated that a skilled thoracoscopic surgeon is able to do the Nuss procedure in Iranian patients with symmetrical pectus excavatum with few complications. However, mixed or redo cases require more expertise.
RESUMO
Bronchopleural fistula (BPF), a sinus tract between the bronchial system and the pleural space, is associated with COVID-19 and can lead to pneumothorax, which increases the mortality rate. Due to the analytical status of COVID-19 patients, sealing the BPF necessitates the least minimal invasive treatment. Herein, we demonstrated a technique of sealing post-COVID-19 BPF with direct injection of cyanoacrylate glue under the guidance of a computed tomography scan. Following glue injection, the BPF was completely sealed in all four patients. In conclusion, in COVID-19 patients with small and distal BPF, percutaneous glue injection is recommended for BPF closure.

BACKGROUND: Pulmonary alveolar microlithiasis (PAM) is a rare autosomal recessive genetic disorder with approximately 1000 known cases worldwide, in which calcium phosphate microliths deposit in the alveolar air spaces. As of writing this report, no definitive conventional therapy exists, and many PAM cases may progress to severe respiratory failure and potential death. Bilateral lung transplantation (BLx) seems to be the most optimal solution; however, this procedure is challenging along with limited reports regarding the outcome in PAM. We report a case of PAM successfully treated with BLx for the first time in Iran. METHOD: We present the case of a 42-year-old female with a longstanding history of cough, not responding to conventional antitussive medication, who was diagnosed as a case of PAM following a hospitalization due to coughing, dyspnea on exertion, and hemoptysis. Despite treatment with corticosteroid and medical treatment, no improvement was achieved and she subsequently developed respiratory and right ventricular failure, with oxygen ventilation dependence. Eventually, she was scheduled for BLx. The operation was successful and during her 2-year follow-up, no recurrence or significant postoperative complications has been reported. CONCLUSION: This case presentation and literature review confirm the effectiveness of BLx as a promising treatment for PAM-diagnosed patients, improving both life expectancy and quality of life.

BACKGROUND: Epithelioid hemangioendothelioma (EHE) is a rare malignancy of vascular origin which can be primarily be seen in various tissues. EHE originating from the pleura is an even more uncommon subtype which may mimic mesothelioma and pleural carcinomatosis. The prognosis of pleural EHE is poor and there is no consensus on the optimal therapeutic approach. CASE PRESENTATION: A 39-year-old middle-eastern female presented with progressive dyspnea and left shoulder discomfort. Chest computed tomography scan revealed a left side pleural effusion and pleural thickening. Pleuroscopy was done and biopsies were taken which were positive for CD31, CD34, CK, factor 8-R-antigen, and vimentin. Patient was diagnosed with pleural epithelioid hemangioendothelioma (PEHE) and chemotherapy was started and underwent extrapleural pneumonectomy 7 months later. Unfortunately, the patient passed away 10 months after diagnosis due to disease complications. CONCLUSIONS: Once PEHE is suspected in histology it can be confirmed with immunohistochemistry. Chemotherapy, surgery or a combination of both is currently used as the treatment but the standard treatment remains a question.

Background and Aims: The incidence of thyroid cancer has witnessed a significant global increase and stands as one of the most prevalent cancers in Iran. This surge is primarily attributed to the escalating incidence of papillary thyroid cancer (PTC), with overdiagnosis emerging as an equally noteworthy factor. Consequently, this study aims to ascertain the incidence of thyroid cancer, along with its clinical presentation, demographic characteristics, and surgical features in patients undergoing thyroid surgery. Methods: This cross-sectional study involved the evaluation of patient files from referral centers in Shiraz spanning the years 2015-2020. Demographic and clinical information pertaining to thyroid cancer was extracted and subsequently analyzed using SPSS software. Results: A total of 533 documented cases of thyroid cancer undergoing surgery revealed an annual rate of 89 cases in our location. The average age of the patients was 43.9 ± 13.4 years (ranging from 13 to 92), with females constituting 429 (83.5%) of the cases, and 278 (54.1%) being malignant. Conventional PTC emerged as the most prevalent pathology, accounting for 239 (45.0%) of the cases. Patients with thyromegaly exhibited significantly higher incidences of nonmalignant tumors (p = 0.01), while those with malignant tumors were notably younger than those with nonmalignant tumors (p = 0.001). Conclusion: Our study revealed a progressive rise in the number of patients undergoing thyroidectomy over the years, with PTC constituting the majority of cases. Malignant cases were more frequently observed in younger patients, and in smaller lesion sizes, highlighting the importance of early screening and optimizing detection methods, especially in high-risk populations.
RESUMO
BACKGROUND: Information regarding computed tomography (CT) scan as a first-line screening tool for diagnosis of foreign body (FB) ingestion is limited to a few studies. This study aimed to discuss the role of low-dose CT scan in diagnosing FB ingestion and its complications in adults, along with its diagnostic values compared to X-ray and esophagoscopy. MATERIALS AND METHODS: In this retrospective, cross-sectional study, all hospital records of adult patients diagnosed with foreign body ingestion from March 2014 to February 2019 were reviewed. RESULTS: Among a total of 114 patients, 41 (36.0%) and 86 patients (85.1%) had positive findings in favor of FB in chest radiographs and CT scans, respectively. Esophagoscopy showed the presence of a foreign body in a total of 95 (83.3%) cases, perforation in 14 cases (12.3%), and laceration in nine cases (7.9%). Also, 12 patients (10.5%) had no findings in their esophagoscopy. The sensitivity, specificity, positive predictive value, and negative predictive value of chest X-ray were 39.2%, 91.7%, 97.6%, and 15.1%, respectively. The sensitivity and specificity of CT were reported to be 96.62% and 100%, respectively. The positive predictive value of the CT method was 100%, and its negative predictive value was 80.0%. CONCLUSION: CT scan can be the preliminary tool for the diagnosis of FB ingestion. It can decrease hospital stay and hospital costs by avoiding unnecessary endoscopy. Due to the insufficiency of X-ray, low-dose CT can be used as a first-line diagnostic tool, especially in cases with ingestion of radiolucent FBs.

BACKGROUND: Cystic echinococcosis (CE)/hydatidosis is an important zoonotic parasitic disease caused by the larval stage of Echinococcus granulosus. The disease is a major health problem all over the world. Finding specific and sensitive biomarkers for follow-up of CE in patients after surgery is essential. Using proteomics methods, the present study aimed to evaluate post-surgical treatment by finding probable biomarker/s in the serum of human lungs CE. METHODS: A total of 24 human sera were tested. These sera included eight confirmed lung/s CE patients sera before surgery (BS), eight sera 12 months post-surgery (12MPS) as well as eight control sera from healthy people. Proteomics methods including 2DE and LC-MS/MS were performed on the specimens followed by bioinformatics analysis. Differentially expressed proteins (DEP) were detected and, separately integrated with protein-protein interaction (PPI) data to construct the PPI network. RESULTS: A total of 171 protein spots were detected in three groups including BS, 12MPS, and control groups; of which a total of 106 DEP have been expressed based on fold changes > = 2 and p-value < 0.05. More analysis was performed and a total of 10 protein spots were selected for identification by mass spectrometry showing the following proteins: APOA1, BGN, SPP2, EAF1, ACOXL, MRPL55, MCTP2, SEPTIN1, B4GALNT1, and ZNF843. Based on centrality parameters of the PPI network (degree and betweenness) five Hub-bottlenecks proteins with significant centrality values were found including APOA1, BGN, SPP2, EAF1, and ACOXL. CONCLUSION: This study showed five proteins as hub-bottleneck proteins; of which APOA1 was more prominent. It can be concluded that a change in expression of this protein in patients' sera could be used as an indicator tool for the achievement of lungs CE surgical therapy.

BACKGROUND: Cavernous hemangioma is a rare benign tumor which can sometimes mimic the clinical presentation and radiological findings of malignant tumors. Here we present a rare presentation of cavernous hemangioma in the mediastinum (CHM), along with a literature review among the main databases. CASE PRESENTATION: We present a 48-year-old male who had suffered from persistent cough as the sole symptom of an anterior CHM. Computed tomography scan demonstrated a 12.5 × 10.8 cm mass in the anterior mediastinum. The mass was surgically resected, and histopathological evaluation established the diagnosis of CHM. The patient was discharged in good condition, in which during his four-month follow-up period, no recurrence of the tumor has been observed. CONCLUSION: Although cavernous hemangioma rarely present in the mediastinum, it should be considered in the differential diagnosis of mediastinal tumors. However, our review of literature demonstrated a female dominance and average age of 40 years, with a 52% mortality rate based on previous reports.

We reported two patients, a 45-year-old lady and a 48-year-old man, known cases of untreated liver and lung hydatid cysts complicated with bronchobiliary fistulae. Surgery was performed, and bronchobiliary fistulae were diagnosed intraoperatively. Lobectomy was done on the lobe, which was chronically infected. Symptoms resolved after surgery in both cases. Green-colored sputum in a patient with a history of echinococcosis should raise the physician's attention to the probability of a connection between the bronchial tree and the biliary tract. Surgery in advanced cases is a suitable therapeutic option.
RESUMO
BACKGROUND: Teratoma is a type of germ cell tumor consisting of one or multiple tissues derived from germinal layers. The location and size of the tumor can cause various presentations. Here we report one of the largest ever cases of immature cystic teratoma. CASE PRESENTATION: In this report, we presented a 24-year-old patient with dyspnea, chest pain, nausea, and anorexia. A computed tomography scan revealed a giant, right-sided mass measuring about 190 × 150 × 140 mm. Chemotherapy was initiated for the patient, followed by thoracotomy. Histopathological evaluation revealed the nature of the mass to be an immature mediastinal teratoma. CONCLUSION: the incidence of immature mediastinal teratoma is uncommon, and due to its rarity, the diagnosis needs more profound evaluation studies such as radiological and pathological assessments. Immature teratomas are optimally treated by a combination of chemotherapy and complete resection.

BACKGROUND: Intrathoracic Solitary Fibrous Tumors (SFT) mainly arise from the pleura; however, these tumors may also originate from the mediastinum. We present a rare case of posterior SFT extending to several mediastinal sites and with an unusual large size, successfully treated with surgical resection. CASE PRESENTATION: A 66-year-old female presented with an initial manifestation of ambiguous pain in the chest and dysphagia and later developed pitting edema in both lower extremities and cachexia five months before admission. Chest imaging confirmed a mediastinal mass (17 × 15 × 8 cm) which was surgically removed. Immunohistochemistry confirmed the diagnosis of a solitary fibrous tumor with positive B-cell lymphoma 2, STAT6, and CD99, negative S100 and smooth muscle actin, and low levels of Ki67 (5-7%). The patient's follow-up course was unremarkable. CONCLUSION: Mediastinal SFTs may grow extremely huge, with the potential to invade multiple adjacent sites. Surgical removal of the tumor remains the mainstay of treatment in these cases.

INTRODUCTION: Descending necrotizing mediastinitis (DNM) is a type of acute mediastinitis that is rarely reported but is regarded as a fatal disease despite improvements in technological methods and antibiotic therapies. We aimed to determine the demographic, clinical, and paraclinical features of patients diagnosed with acute DNM. METHODS: In this retrospective study, patients' hospital records with a diagnosis of DNM admitted to the Namazi hospital in southern Iran during 18 years (2002-2019) were reviewed. Demographic and clinical features were recorded and subsequently analyzed via SPSS 22. RESULTS: Out of 67 mediastinitis patients, 25 (37.3%) were diagnosed as DNM with an average age of 37.2 ± 16.7 years, and 68% were male. Regarding etiology, 52.0% were due to neck infection. Based on the technique of surgery, 52% of the patients underwent the combined method, which was mostly among type I and IIA DNM, while thoracotomy was mostly performed on type IIB DNM (P = 0.08). Based on the incision, type IIA and IIB had the highest frequency of thoracotomy and cervicothoracic incisions (P = 0.02 and 0.002). Puss discharge was significantly lower in type I DNM (P = 0.01). Based on the presenting symptoms of our patients, the majority (72.0%) had a chief complaint of neck pain, followed by chills and fever (48%). There were no reports of mortality during our short-term follow-up. CONCLUSION: We report one of the largest retrospective studies of DNM patients in our referral center, with a high prevalence of the disease among younger populations, especially under 40 years. The method of treatment should be chosen based on the extent of infection and can be limited to neck exploration in upper mediastinal infections, though thoracic or combined approach in more broad infections.
