Publication Open Access Two Self-Stabbing Pneumothorax Cases(2018-07-01T00:00:00Z) Sonmez, Ertan; Ozkan, Abuzer; Gulen, Bedia; Metin, Huseyin; Akdemir, Osman Cemil; SÖNMEZ, ERTAN; METİN, HÜSEYİN; AKDEMİR, OSMAN CEMİLSelf-inflicted chest stabbing complicated with tension pneumothorax (TPX) is a rare condition. We report two stabbing cases which were complicated with pneumothorax and were successfully treated.Publication Open Access Persistent pleural effusion in an infant with an unusual diagnosis: congenital alveolar rhabdomyosarcoma(2020-01-01T00:00:00Z) Yozgat, Can Yilmaz; YEŞİLBAŞ, Osman; YOZGAT, Yılmaz; AKDEMİR, OSMAN CEMİL; YURTSEVER, İsmail; TEKİN, NUR; BAGHISHOV, DAMAT; BAYRAMOVA, NİGAR; ELAGÖZ, Şahande; ÇAKIR, FATMA BETÜL; YEŞİLBAŞ, OSMAN; YOZGAT, YILMAZ; AKDEMİR, OSMAN CEMİL; YURTSEVER, İSMAİL; TEKİN, NUR; BAGHISHOV, DAMAT; BAYRAMOVA, NİGAR; ELAGÖZ, ŞAHANDE; ÇAKIR, FATMA BETÜLRhabdomyosarcoma (RMS) is a malignant form of neoplasm that originates from skeletal muscle. RMSs can exist anywhere in the human body but are more commonly detected in the neck region and extremities. The alveolar type is one of the subtypes of RMS that has a poor prognosis. Because the clinical manifestation of a tumour can be a painless mass, symptoms might be non-contributary to the diagnosis. Herein, a four-month-old girl was admitted to the emergency department with complaints of respiratory distress without a runny nose, cough, and fever. Recurrent effusions subsided with subsequent tube thoracostomy. Video-assisted thoracoscopic surgery (VATS) was performed to determine the aetiology of the recurrent effusion. The Tru-Cut biopsy obtained during VATS resulted in the diagnosis of alveolar rhabdomyosarcoma. Pleural effusion decreased, and the tube drainage was stopped rapidly after first vincristine, actinomycin-D, and cyclophosphamide chemotherapy cycle. Persistent and recurrent pleural effusions should alert physicians to rule out unusual diagnoses like that of our case.Publication Open Access Merkel Cell Carcinoma(2023-01-01) Sönmez Ergün, Selma ; Kirazoğlu, Ahmet; Akdemir, Osman Cemil; Su Küçük, Özlem; Altınok, Pelin; Yıldız, Pelin; ERGÜN, SELMA; AKDEMİR, OSMAN CEMİL; KİRAZOĞLU, AHMET; YILDIZ, PELİN; SU KÜÇÜK, ÖZLEM; ALTINOK SÜT, PELİNMerkel cell carcinoma (MCC) is a rare tumor that arises from mechanoreceptor Merkel cells. Ultraviolet exposure, immunosuppression and Merkel cell polyoma virus play a significant role in tumor pathogenesis. Although it typically presents as an initially indolent growing, painless solitary lesion, the course of MCC may be aggressive due to the nodal invasion, distant metastasis and high recurrence rates. We presented a case of MCC with a background history of rheumatoid arthritis treated with immunosuppressive therapy for many years who had necrotizing granulomatous lymphadenitis.Publication Open Access Determination of standard number, size and weight of mediastinal lymph nodes in postmortem examinations: reflection on lung cancer surgery(2013-04-16T00:00:00Z) Zıyade, Sedat; Pınarbasılı, Nb; Zıyade, N; Akdemır, Osman Cemil; Sahın, F; Soysal, Ömer; Toker, A; ZİYADE, SEDAT; AKDEMİR, OSMAN CEMİL; SOYSAL, ÖMERBackground Mediastinal lymph node dissection is an essential component of lung cancer surgery. Literature lacks established information regarding the number and size of the healthy lymph nodes. In this postmortem autopsy study, we aim to define the number, size and weight of the lymph nodes in each mediastinal lymph node station. To implement the data for the clinical practice, we analyzed the possible number of nodes to be dissected in a systematic mediastinal lymph node dissection from the right and left sides during lung cancer surgery. Methods Sixty-two samples obtained from cadavers who did not die from chest malignancies, extrathoracic malignancies, any kind of infections or previous hospitalization before the death were included to the study. The locations of the nodes were recorded according to the American Thoracic Society Mediastinal Lymph Node Map. The number, size and weight of the nodes were determined at each station. Results Median age of the cadavers was 39 years. Primary causes of death were asphyxia in 10 (16.1%) subjects, trauma in 29 (46.8%) subjects, cardiovascular problems in 10 (16.1%) subjects, and undetermined in 13 (21%) subjects. The median number of lymph nodes resected from each patient was 23 (range: 11–54). The right sided paratracheal lymph nodes (Station 2R and 4R) were more frequent, heavier and longer than left sided lymph nodes (Station 2L and 4L) at the paratrecheal region. Right sided inferior mediastinal lymph nodes were heavier and longer than the left ones; however, their availability was more often on the left. Conclusions The properties of mediastinal lymph nodes at particular stations are different for number, size and weight. Station 4R and 7 have the highest number of nodes followed by stations 5 and 6. We recommend removing the lymph nodes of these stations completely in lung cancer patients to rule out the possibility of micrometastatic disease. Diameter of normal lymph node may be 1 cm for the stations other than 4R and 7, but the definition of normal diameter of a lymph node at the stations 4R and 7 may be changed as 1,5 cm and 2,0 cm, respectively. Weight of the nodes may be a new subject to study and may be defined as a new modality to define a staging to be more accurate and the issue needs further investigations.Publication Open Access Management of sternal segment dislocation in a child with closed reduction.(2012-01-01T00:00:00Z) Soysal, O; Akdemır, Osman Cemil; Zıyade, Sedat; Ugurlucan, M; SOYSAL, ÖMER; AKDEMİR, OSMAN CEMİL; ZİYADE, SEDATPublication Open Access Enostosis of Clavicle Causing Severe Dyspnea by Compressing the Trachea Externally: Case Report(2019-04-01T00:00:00Z) AKDEMİR, OSMAN CEMİL; KÖK, ABDÜLAZİZ; ZİYADE, Sedat; ELMADAĞ, Nuh Mehmet; ÇAKIR, Erkan; BİLGİN, MEHMET; SOYSAL, ÖMER; Buyukpinarbasli, Nur; AKDEMİR, OSMAN CEMİL; KÖK, ABDÜLAZİZ; ZİYADE, SEDAT; ELMADAĞ, NUH MEHMET; ÇAKIR, ERKAN; BİLGİN, MEHMET; SOYSAL, ÖMERClavicle is the bone that forms anterior border of shoulder arch. It lies on anterosuperior of thorax with first rib. Clavicle is very near to major vascular structures, brachial plexus, esophagus and trachea at thoracic inlet. Because of this, clavicular lesions fractures and sternoclavicular dislocations -especially posterior dislocations- may cause symptoms due to compressing symptoms due to these structures. In this article we present a case with enostosis of clavicle causing respiratory failure by compressing on trachea.
