Evaluation of effects of curcumin on acute esophagitis in the corrosive esophagitis model in rats.

Ingestion of a corrosive substance may cause corrosive esophagitis. Curcumin has anti-inflammatory and mucosal protective effects. In this study, the effects of curcumin on the acute phase of corrosive esophagitis were investigated. Twenty-seven Wistar Albino rats were divided into four groups; sham (group I), control (group II), and experiment groups (group III, 100 mg/kg curcumin; group IV, 200 mg/kg curcumin). Forty percent sodium hydroxide solution was used to erode the esophagi of rats in groups other than the sham group. Curcumin was applied to animals in the experiment groups 10 min after the corrosion. After 24 h, animals were sacrificed, and esophagus samples were collected. According to the histopathological examination, the muscularis mucosa damage was regressed from 100% in group II to 71.4% in group III and 50% in group IV. Mild level of damage and collagen deposition in the tunica muscularis regressed from 66.7% of the animals in the control group to 42.9% in group III and to none in group IV. Further, an increase in submucosal collagen was present in all samples from groups II and III, while 83.3% of samples had an increase in submucosal collagen in group IV. There was a significant difference in the histopathological total score between the control group and group IV (p=0.02). The results showed that the administration of curcumin in a dose-dependent manner can relieve the acute phase of corrosive esophagitis.

Clinical importance of serum and pleural fluid prominin-1 and hypoxia-inducible factor-1α concentration in the evaluation of lymph node involvement in patients with malignant pleural effusion.

Introduction: Malignant pleural effusion (MPE) and lymph node metastasis (LNM) presence are poor prognostic factors that have importance for cancer patients. The study objective was to determine whether hypoxia-inducible factor-1α (HIF-1α) and prominin-1 (CD133) in pleural fluid (P) and serum (S) could be used as biomarkers for diagnosis of lymph node involvement in patients with MPE. Materials and methods: Fifty-six patients with MPE and 30 healthy control subjects were included. Computerized tomography (CT) and positron emission tomography (PET) were used to diagnose pleural effusion. Patients with malignant cells in pleural fluid cytological examination were included in the MPE group. Thirty-five patients with lymph node metastases on CT were included in the LNM-positive MPE group. Serum and pleural fluid HIF-1α and CD-133 concentrations were measured manually via enzyme-linked immunosorbent assay (ELISA). Results: Serum concentrations of HIF-1α and CD133 were higher in MPE patients. It was found that CD133/HIF-1α (S) ratio was higher in the malignant patient group with positive lymph node involvement than in the negative group, while concentrations of HIF-1α (P) were lower. Pleural fluid HIF-1α and CD133/HIF-1α (S) ratio had sufficient performance in diagnosing lymphatic metastases in patients with MPE (AUC = 0.90 and 0.83, respectively). Conclusions: In conclusion, serum HIF-1α and CD133 concentrations were higher in patients with MPE, consistent with our hypothesis. Concentrations of HIF-1α (P) and CD133/HIF-1α (S) ratio can be used as biomarkers in diagnosing lymph node involvement in MPE patients, according to this experiment.

Post-tuberculosis Pneumocytoma.

Pneumocytoma is a rare benign tumor of the lung that usually manifests as a solitary pulmonary nodule. A 69-year lady, who had history of tuberculosis treatment 20 years ago, admitted to the hospital. A round mass was seen on chest radiography. Thorax computed tomography was reported as a round lesion in the left lung. Fiberoptic broncoscopy, computed tomography-guided fine-needle aspiration cytology and intraoperative frozen section analyses were undiagnostic. We performed wedge resection with minithoracotomy. Pathologic examination was reported as pneumocytoma. The patient did not receive any chemotherapy or radiotherapy after the operation. After 41 months' follow-up, no recurrent lesion was seen.

Management of foreign body ingestion and food impaction in adults: A cross-sectional study.

BACKGROUND: The management of food impaction and foreign body ingestion in the upper gastrointestinal tract requires careful evaluation and timely intervention. This study was a retrospective evaluation of the management of adult patients with such a history. METHODS: This study included adult patients admitted to a tertiary medical center with foreign body ingestion or food impaction between January 2012 and January 2018. The demographic and clinical data were recorded pro forma for statistical analysis. RESULTS: Of the 122 patients included in this study, 53.2% were male, and the mean age was 46.68+-18.64 years. In 84 of the patients (68.8%), the ingested object was food. Thirty patients were managed solely through laryngoscopy, while 61 patients (50%) underwent a flexible endoscopy. The patients with a foreign body ingestion were older than those with a food impaction (mean age: 51.3+-17.4 vs. 36.5+-17.4 years; p<0.001) and a plain radiograph showed the ingested material more often in those patients (36.8% vs 10.7%; p<0.001). Two patients underwent surgery due to perforations caused by the impacted material. No mortality was observed. CONCLUSION: The management of a foreign body ingestion or food impaction in an emergency setting requires a stepwise, algorithmic approach.

Surgical Treatment of Spontaneous Pneumothorax: Pleural Abrasion or Pleurectomy?

PURPOSE: A primary spontaneous pneumothorax is a condition that occurs predominantly in young and thin male individuals who do not have any history of underlying lung disease. Various techniques such as pleural abrasion and pleurectomy are used to reduce the recurrence rate, but there exists no consensus among surgeons on which surgical technique offers the lowest risk of recurrence.We aimed to compare the efficiency and recurrence risk of pleural abrasion and pleurectomy methods in patients with primary spontaneous pneumothorax undergoing a wedge resection for the bulleous part of the paranchyme. MATERIALS AND METHODS: Statistically compared variables between the 2 groups were age, sex, symptoms, smoking status, number of previous pneumothorax episodes, surgical indication, bleb number, estimated blood loss, intraoperative complication, duration of the surgery, conversion to open surgery, postoperative drainage amount, chest tube removal time, length of hospital stay, morbidity, mortality, duration of narcotic analgesic usage, pain according to Visual Analog Scale evaluation, follow-up period, and postoperative recurrence. RESULTS: The medical records of 88 patients undergoing surgery between 2013 and 2017 were reviewed retrospectively. The pleural abrasion group was superior to the pleurectomy group in terms of operation time, drainage volume, time to drain removal, hospital stay, and Visual Analog Scale pain score on postoperative day 0. Statistically, there was no difference between the pleural abrasion group and the pleurectomy group in the recurrence rates after operation (2.0% vs. 2.5%, respectively; P=0.89). CONCLUSIONS: Thoracoscopic pleural abrasion is safer than apical pleurectomy and is associated with the same pneumothorax recurrence rate.

Successful Treatment of a Late Diagnosed Esophageal Perforation with Mediastinitis and Pericardial Abscess.

We herein report a case of late diagnosed thoracic esophageal perforation. A 60-year-old man was diagnosed as an esophageal perforation with mediastinitis and pericardial abscess by detailed history taking, chest computed tomography, esophagoscopy and inflammatory findings in his blood test. Surgical drainage of mediastinum and pericardium was able to effectively control infectious process and pericardial fibrosis. Endoscopic esophageal stent placement on the thoracic- esophageal fistula promoted healing of the esophageal wall defect and enabled him to restart oral intake. This case report suggests that detailed history taking is important for all patients. Effective drainage of mediastinum and the use of esophageal stent may be the treatment options for late-diagnosed esophageal perforation.

Large Cell Carcinoma with Adenocarcinoma in Lung.

Large cell neuroendocrine carcinoma (LCNC) is a rare and aggressive cancer accounting for 3% of all lung cancers. A small percentage of LCNC called combined LCNC, can be seen in combinations with other lung tumor types. Multimodal therapy is proposed for this type of tumor but there is no any significant therapy since it is very rare tumor. This patient was a 66-year male and a heavy smoker with no symptoms of lung disease. Computed tomography core biopsy showed suspected adenocarcinoma. Right lower lobectomy was performed with mediastinal lymph node dissection via mini thoracotomy. The tumor was diagnosed as combined LCNC with adenocarcinoma. The patient was discharged on the seventh postoperative day and sent to the oncology clinic for chemotherapy. There has been no recurrence for eight months after surgery.

Blunt Diaphragmatic Injuries: Pericardial Ruptures.

Blunt traumatic diaphragmatic injuries (BTDIs) can be misdiagnosed. Careful evaluation of associated injuries in BTDI is important. In this study, we evaluated treatment options and difficulties in the diagnosis of patients with BTDI. We evaluated ten patients retrospectively with BTDI admitted to our departments, between January 2004 and 2015. Age, gender, trauma type, symptoms, radiological findings, diagnosis time, location and grade of the diaphragmatic injury, surgical type of repair, associated injuries and pericardial rupture, and morbidity and mortality rates were recorded. The mean age of the patients was 46.7 years, and all were males. Ninety percent of BTDI was left sided, and 10 % was on the right side. The diagnosis was confirmed with chest radiograph in 50 % and computed tomography in 70 %. Radiological examination revealed hemothorax in 80 %, the loss of diaphragmatic shadow in 60 %, and visceral organ herniation to the thorax in 60 %. Multiple organ injuries were present in 90 % of cases. Pericardial rupture seen in 30 % was remarkable. Early surgery was performed for eight patients and late surgery for two patients. There were six patients with grade 4 or 5 central diaphragmatic injuries (CDIs). Multiorgan injury was present in all patients developing acute CDI. Multiple organ injury is much higher in patients with severe acute blunt trauma with CDI. Pericardial rupture rate is high in cases with acute BTDI and CDI. Proper diagnosis and early surgical management reduce morbidity and mortality.

Video-assisted minimally invasive diaphragmatic plication: feasibility of a recognized procedure through an uncharacteristic hybrid approach.

BACKGROUND: Diaphragmatic plication is an approved surgical procedure for treatment of symptomatic diaphragmatic paralysis and eventration. We aim to define our minimally invasive technique of plication and objectively assess our surgical outcomes of the largest series reported in the literature so far, using pulmonary function tests. METHODS: Symptomatic patients whom were planned to undergo plication using video-assisted mini-thoracotomy between December 2009 and December 2015 were the cohort of this retrospective study. Single camera port and a utility incision (3-4 cm) were used for access. Data of patient demographics with preoperative and postoperative spirometric results were collected for statistical comparison. RESULTS: Procedure (30 left, 7 right) was completed in 37 (27 male, 10 female) patients. One patient was excluded because of insufficient objective postoperative comparison criteria due to previous permanent tracheostomy. Mean length of surgery was 48.8 ± 19.7 (range: 30-70) min. Postoperative overall morbidity was 8.3 %, with no mortality. The mean length of hospital stay was 3.1 ± 1.7 days. All patients except one (97.3 %) were asymptomatic on discharge and on follow-ups. Significant improvement in measurements of forced expiratory volume in 1st second was observed on postoperative measurements (P < 0.001), with a mean overall increase of 13 % in whole cohort. No recurrence was detected throughout a mean follow-up of 19 months. CONCLUSIONS: Diaphragmatic plication via video-assisted mini-thoracotomy is an effective and curative surgical procedure which can be performed successfully with low morbidity rates. As it combines the rapidity and economical benefits of open thoracotomy with the advantages of video thoracoscopic procedures such as fast recovery and short postoperative hospital stay, it can be preferred as a safe and effective alternative hybrid method compared to standard open or closed techniques, for symptomatic patients with non-functional hemidiaphragm.

Pneumomediastinum after Tooth Extraction.

Pneumomediastinum is defined as the presence of air in mediastinum. Pneumomediastinum can sometimes occur after surgery. Pneumomediastinum seen after dental procedures is rare. We presented the case of subcutaneous emphysema developed in the neck and upper chest after tooth extraction and discussed the possible mechanisms of pneumomediastinum.

Multidetector computed tomography findings of central bronchopleural fistulas as sequelae of tuberculosis, chemo radiation and trauma: A report of three cases.

A bronchopleural fistula (BPF) is defined as a direct pathway between the bronchial tree or lung parenchyma and the pleural space. Herein, we describe the clinical findings and imaging results of BPFs in three cases. The patients' medical histories revealed that the first had recurrent pulmonary tuberculosis, the second had small-cell lung cancer (SCLC) and had previously undergone chemoradiotherapy, and the third had trauma. Multidetector computed tomography (MDCT) showed clear communication between the airways and pleural spaces which was sufficient for a proper diagnosis without performing a bronchoscopy.
