Diagnostic delay may cause an increase in mortality and morbidity in cases without acute respiratory failure. We report our diagnostic and therapeutic modalities. Methods: In our department, bronchoscopy was performed on 548 patients with the diagnosis of tracheobronchial foreign body aspirations (from 1987 to 1997). Of these cases, 55.6% were male and 44.4% female. Their ages ranged from 2 months to 16 years (average 5.5 years). Diagnosis was made on history, physical examination, radiological methods and bronchoscopy. Results: Foreign bodies were localized in the right bronchial tree in 312 cases (56.9%), the left in 126 cases (23.0%) and in the trachea in 62 cases (11.3%). Foreign body was not found during bronchoscopy in 48 cases (8.7%). The majority of the foreign bodies were vegetable matters. Foreign bodies were removed with bronchoscopy in all but two cases which underwent limited thoracotomy. In the late period, pulmonary resection was performed in five cases because of irreversible complications. After bronchoscopy, hypoxia developed in four patients, requiring mechanical ventilation. Pneumothorax developed in two cases and mediastinal emphysema in two. Four patients (0.7%) died because of respiratory failure. Conclusion: Proper use of diagnostic techniques provides a high degree of success, and the treatment modality to be used depending on the type of the foreign body is mostly satisfactory.

ABS TRACT Dermatofibrosarcoma protuberans (DFSP) is a painless, slowly growing, rare skin tumor. ... more ABS TRACT Dermatofibrosarcoma protuberans (DFSP) is a painless, slowly growing, rare skin tumor. It is most common in the trunk part of the body. It is frequently seen in the 40s. It is usually a low-grade sarcoma. DFSP, which is a locally benign-aggressive tumor, begins with a small size and may infiltrate the skin, subcutaneous adipose tissues, muscles and bones, and may recur despite extensive excision. It never metastasize without higher grade fibrosarcomatous changes. Although the benefit of chemotherapy and radiotherapy is limited, it can be applied in cases of recurrence or metastasis. We present a case of DFSP without skin lesions in a 46-year-old woman presenting with a slow-growing mass on her back. The mass was removed with a wide surgical margin. We aimed to emphasize that DFSP, which is very rare, can be seen without dermal involvement.

Methods: Thirty two patients admitted with ingesting button batteries were retrospectively evaluated. Chest x-ray was ordered for diagnosis. Hospital stays, interventions , complications and mortality of the patients were collected. The time between the patients ingested the buton battery and its removal was defined as its duration in esophagus. All the patients underwent rigid esophagoscopy under general anasthesia. Buton batteries at the first narrowing were removed by magyl clamp. Results: 21 of 32 patients were female, with a mean age of 22 months. The mean duration of ingestion was 17 hours. The mean hospital stay was 10 days. Of the patients, 75% were admitted within 24 hours. Complication rate was 19% and mortality rate was 6%. There was a strong correlation among the number of the cases and the coming years (p<0.001). Linear regression test was used in the number of cases and the duration ...

Methods: An empyema was induced in 21 rabbits after inoculation of Staphylococcus aureus. Glucose levels, pH, lactate dehydrogenase levels, and amounts of pleural drainage were evaluated in addition to pleural and empyema scores. The rabbits were divided into three groups, each 7, the isotonic solution, the streptokinase, and the ecballium group. Results: At autopsy, there was no difference in pH, glucose, and LDH levels in three groups. The mean pleural drainage was greater in the ecballium group. A significant difference was detected between groups in terms of drainage amounts and pleural and empyema scores (P < 0.05). A significant difference in pleural and empyema scores was detected in the ecballium and streptokinase groups (P < 0.05). EE group had significant differences in drainage amounts and plural and empyema scores regard to the control group (P < 0.05). No si...

Hydatid cyst is a parasitic disease well known for years are commonly located in liver and lungs. Those intradiaphragmatic and intramyocardiac were diagnosed preoperatively but those lying subcutaneously on sternum and the right first rib were recognized after operation. They were also confirmed with pathologic study. Patients were also detected for hydatid cysts elsewhere. As an endemic disease in our country, atypical locations should be kept in mind. This disease is to be remembered in considering soft tissue tumors. J Clin Exp Invest 2013; 4 (3): 352-355 OZET Baska bir yerde primer kaynak saptanamayan atipik lo

Its anti-inflammatory role in sepsis is not well understood. We investigated the effects of EE on serum levels of proinflammatory cytokines and further explored the mechanisms underlying histological changes in liver and ileum following EE administration in a polymicrobial sepsis model. Thirty rats were divided into three groups of 10 rats each. Rats were subjected to sham laparotomy plus normal saline administration (control group, CG), laparotomy with cecal ligation and puncture (CLP) (sepsis group, SG), and laparotomy with CLP plus 2.5 mg/kg EE administration (experimental group, EG). Twenty-four hours after laparotomy, animals underwent cardiac puncture, and blood was collected for interleukin 1 (IL-1), interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) assessment. Whole sections of liver and ileum tissues were collected for histologic examination. The serum level of IL-6 was significantly lower in EG as compared to SG. Although IL-6 levels were shown a statistically significant (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.0001) decline to near control values, no significant changes were observed in serum levels of IL-1 and TNF-α after EE treatment. Histologic examination revealed statistically significant reduction in collagen formation (p = 0.001) on serosal surface of ileum and hepatic venous congestion (p = 0.040) in EG as compared to SG. EE might play a protective role in sepsis prevention and treatment by decreasing IL-6 production and reducing liver damage and may influence bacterial translocation by reinforcing intestinal barrier function.

We wanted to demonstrate our surgical practice and outcome of surgical treatment in bronchiectasis. We studied records of 60 pediatric patients who underwent surgical resection in our clinic between January 2000 and January 2013. The results were analyzed regarding factors influencing the outcome. There were 32 boys and 28 girls with a mean age of 9.45 years (range 2-15). The most common cause was childhood infection in 25 (41.66%). The mean duration of the symptoms was 42.93 months. Patients underwent 64 operations including 2 staged thoracotomies and 2 re-thoracotomies. Atelectasis was the most frequent complication. Longer duration of symptoms related to postoperative complication. The morbidity and mortality rates were 20% and 3.33%, respectively. The outcome was optimal in 92%. Forced expiratory volume in 1 s less than 60% of the predicted value, hemoptysis and duration of symptoms were found prognostic variables for postoperative morbidity with high ratios of odds coefficients by using Binary Logistic Regression Method. Complete and early resection of bronchiectasis provides a successful outcome. Duration of symptoms and timely intervention have a major impact on the management and prognosis.

It has anomalous systemic supply rather than the pulmonary circulation and no connection with the tracheobronchial tree. It may present as respiratory infection or asymptomatic mass on chest imaging studies. Surgical removal is the treatment of choice. This paper presents a case of intralobar pulmonary sequestration that presented during childhood.

Extrapulmonary location of the disease in the thorax is very rare, and surgical procedures can be considered that differ from those used for pulmonary hydatid cysts. We reviewed retrospectively our experience in the surgical treatment of 22 patients with intrathoracic, extrapulmonary hydatid cysts. In our department, 297 patients with thoracic hydatid cysts were managed surgically in the last 14 years, in 22 (7.4%) of whom the cysts were localized extrapulmonarily in the thorax. The locations of these hydatid cysts were a fissure, the pleural cavity, chest wall, mediastinum, myocardium, and diaphragm. Total resection was chosen as the surgical procedure in all patients except 4 (18.2%), 1 of whom had cystectomy and capitonnage for cardiac hydatid cyst and 3 of whom had cystectomy and local curettage for cysts located in the chest wall. Empyema developed postoperatively in 1 case (4.5%) with a cyst in the fissure. The follow-up period was 1 year, and there were no deaths. Hydatid cyst may be found in many different sites, including extrapulmonarily in the thorax, and bearing this in mind will facilitate planning of the operation.

Both diseases are characterised by similar symptoms. We aimed to emphasise that some forms of TB are associated with misleading clinical and radiological manifestations. We present a retrospective study of clinical and pathological results of 10 cases with a preliminary presumptive diagnosis of thoracic malignancy. All patients were found to have TB without evidence of malignancy and were successfully treated with standard antibiotherapy after completion of diagnostic procedures. TB should be considered as a noteworthy differential diagnosis in patients living in TB-endemic countries, and biopsy plays a vital role in correctly diagnosing TB.
