Publication Open Access Parathyroid allotransplantation in rabbits without cultivation.(2014-01-15) CAN, I; YUCESAN, E; Aysan, E; SAYITOGLU, M; OZBEK, U; ERCIVAN, M; ATASOY, H; BUYUKPINARBASILI, NUR; MUSLUMANOGLU, M; AYŞAN, MUSTAFA ERHAN; YÜCESAN, EMRAH; BÜYÜKPINARBAŞILI, NURPermanent hypoparathyroidism is a serious clinical situation. Allotransplantation of the parathyroid cells is relatively new approach to treatment. Non-cultivated allotransplantation in rabbits is not tried before. In this research parathyroidectomy was performed in six female New Zealand white rabbits. After division of surgically removed tissues into two, cryopreservation after cell isolation was done. Non-cultivated cross allotransplantation was performed under immunosuppression. Serum calcium and phosphorus levels were observed 15 days and histopathological analyses of the transplanted parathyroid tissues were studied. Significant changes in serum calcium and phosphorus levels during the experiment were observed (p=0.001 for both). Calcium levels which were significantly dropped to 6.66±0.7 mg/dL after parathyroidectomy and progressively increased up to 15.98±1.25 mg/dL at the end of the experiment (p=0.004). Phosphorus levels which were increased to 9.38±0.63 mg/dL after parathyroidectomy and stabilized to 4.46±1.06 mg/dL at the end of the experiment (p=0.007). All allotransplanted parathyroid tissues showed normal tissue architecture without evidence of cellular rejection. In conclusion allotransplantation of the parathyroid tissues without cultivation may be considered as an alternative and safe approach for the treatment of permanent hypoparathyroidism.Publication Open Access A Rare Case: Mucous Membrane Plasmacytosis in the Larynx(2014-07-01) BÜYÜKPINARBAŞILI, NUR; ÇOBAN, GANİME; GÜCİN, ZÜHAL; Meriç, Ayşenur; BÜYÜKPINARBAŞILI, NUR; ÇOBAN, GANİME; GÜCİN, ZÜHALMucous membrane plasmacytosis is a rare reactive process characterized by plasma cell infiltration of mucous membranes for unknown reasons. It may be confused with malignancy because of its exophytic structure and pavement appereances. A laryngeal polypoid lesion was sent to the pathology department, clinically called fibroma, and presented to emphasize the diagnostic and differential diagnostic criteria.Publication Open Access Giant Cell Arteritis of the Breast(2015-12-01T00:00:00Z) Buyukpinarbasili, Nur; GÜCİN, ZÜHAL; ERSOY, YELİZ EMİNE; YILDIZ, ŞEYMA; BÜYÜKPINARBAŞILI, NUR; GÜCİN, ZÜHAL; ERSOY, YELIZ EMINE; YILDIZ, ŞEYMASystemic vasculitis such as Wegener-s granulomatosis (WG), giant cell arteritis (GCA), and poliarteritis nodosa (PAN) may produce tumor-like masses in various organs. GCA may affect large vessels and also rarely present with primary visceral involvement in the breast. In these situations, GCA may confuse with malignancy because of characteristics such as tenderness, redness, and mass formation. This article presents a case report on an 87-year-old woman with palpable mass in her breast and was diagnosed as GCA in the biopsied lesion.Publication Open Access Estrogen Receptor Positive/Progesterone Receptor Negative Breast Carcinomas: A Subgroup Deserves Particular Interest(2015-08-01) Gucin, ZÜHAL; GECER, Melin Ozgun; Buyukpinarbasili, NUR; SONMEZ, Cavide; Ersoy, YELİZ EMİNE; MUSLUMANOGLU, Mahmut; GÜCİN, ZÜHAL; BÜYÜKPINARBAŞILI, NUR; ERSOY, YELIZ EMINEObjective: Breast carcinomas positive for the estrogen receptor (ER+) but negative for the progesterone receptor (PR−) have unfavorable prognostic features and are resistant to tamoxifen therapy. The goal of this study was to highlight the significance of PR− breast carcinomas. Methods: Therefore, 146 breast carcinomas comprising 87 ER+/PR+ and 59 ER+/PR− carcinomas were examined. These two groups were compared in terms of age; tumor type; tumor size; histologic grade; presence of an in situ component; lymphovascular and perineural invasion; and ER, PR, c-Erb B2, Ki-67, and epidermal growth factor receptor (EGFR) status. Results: While the number of metastatic lymph node and related pN2+pN3 tumors were found to be significantly higher in the ER+/ PR− group, the differences with respect to the tumor size, metastatic lymph node size, and frequency of lymphovascular invasion were nearly significant. Conclusion: ER+/PR− tumors have an unfavorable prognosis and show a clinical behavior closer to triple negative ones, although classified as luminal tumors. Revealing the mechanisms causing these differences will enhance the success of breast cancer therapy.Publication Open Access Leiomyoma of the esophagus: open versus thoracoscopic enucleation(2014-01-01) Ziyade, SEDAT; Buyukpinarbasili, NUR; YEDIYILDIZ, Senel; Kadioglu, HÜSEYİN; Soysal, Omer; ZİYADE, SEDAT; KADIOĞLU, HÜSEYİN; BÜYÜKPINARBAŞILI, NUR; SOYSAL, ÖMERBackground/aim: To describe a novel, easy, and secure thoracoscopic surgical approach for esophageal leiomyomas.Publication Open Access Disseminated scar sarcoidosis may predict pulmonary involvement in sarcoidosis.(2013-09-01) Su, O; ONSUN, NAHİDE; TOPUKÇU, B; OZÇELIK, HK; CAKıTER, AU; BÜYÜKPıNARBAŞıLı, NUR; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDE; BÜYÜKPINARBAŞILI, NURSarcoidosis is a chronic, inflammatory, multi-organ disease of unknown origin that is characterized by non-caseating granuloma formation in affected organs. Cutaneous involvement is reported in 25% of patients with sarcoidosis. Scar sarcoidosis is rare but is clinically specific for skin sarcoidosis. Systemic involvement is seen in most patients with scar sarcoidosis. We present a case of scar sarcoidosis in a 30-year-old male that developed infiltrated nodules on old scars, including on his penile shaft, which is rare, and that also had pulmonary involvement. Scar sarcoidosis should be considered in the differential diagnosis of changes in all scar areas and should be investigated for systemic involvement.Publication Open Access A Six Sigma Trial For Reduction of Error Rates in Pathology Laboratory(2016-09-01) TURNA, Seval; Tosuner, ZEYNEP; Gucin, ZÜHAL; Kiran, TUĞÇE; Buyukpinarbasili, NUR; TASKIRAN, Olcay; Arici, DİLEK SEMA; TOSUNER, ZEYNEP; GÜCİN, ZÜHAL; KIRAN, TUĞÇE; BÜYÜKPINARBAŞILI, NUR; TURNA, SEVAL; ARICI, DILEK SEMAObjective: The aim of this study is to determine differences of levels of empathy among undergraduates in each year of their four-year programs of physiotherapy. Methods: During the 2014-2015 academic school year, 381 physiotherapy students were enlisted from two universities in Istanbul, one a foundation and the other a government university. The Turkish version of the Jefferson Scale of Physician Empathy was administered. Students were asked to indicate interest in particular physiotherapy specialties as well as their region of origin in Turkey. The Kruskal-Wallis analysis was used to determine differences among the four study years, and also to measure relationships between specialty interest, home-region, and empathy scores of the students. Empathy scores were also compared according to gender. Results: The difference of empathy scores between the students of the two universities was borderline significant (p=0.057). Empathy scores in both universities increased to a significant degree after school entrance and decreased in the final year. Levels of empathy did not change according to gender, specialty interest, or home-region (p=0.722, 0.524, and 0.309, respectively). Conclusions: This study points to the need for physiotherapy curricula that would enhance empathy and give students practice in exhibiting this valuable attribute. Additional studies are needed that would include larger study populations and track the same students year by year as to how and why their empathy levels change during their training.Publication Open Access Incidental detection of prostate-specific antigen-negative metastatic prostate cancer initially presented with solitary pulmonary nodule on fluorodeoxyglucose positron emission tomography/computed tomography(2015-01-01) ERDOĞAN, EZGİ BAŞAK; Buyukpinarbasili, NUR; ZİYADE, SEDAT; AKMAN, Tolga; TÜRK, HACI MEHMET; AYDIN, MEHMET; ERDOĞAN, EZGİ BAŞAK; BÜYÜKPINARBAŞILI, NUR; ZİYADE, SEDAT; TÜRK, HACI MEHMET; AYDIN, MEHMETA 71-year-old male patient with solitary pulmonary nodule underwent fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) showing slightly increased FDG uptake in this nodule. In addition, PET/CT detected hypermetabolic sclerotic bone lesions in the right second rib and 7(th) thoracic vertebrae, which were interpreted as possible metastases, and mildly increased FDG uptake in the prostate gland highly suspicious of malignancy. The patient's prostate-specific antigen (PSA) level was within normal range (3.8 ng/dL). The histopathological examination of the lung nodule and right second rib lesion proved metastases from prostate cancer, then the prostate biopsy-confirmed prostate adenocarcinoma. The unique feature of this case is to emphasize the importance of performing PET/CT for solitary pulmonary nodule in detecting PSA-negative metastatic prostate cancer. This case indicated that it should be kept in mind that, even if the PSA is negative, a lung metastasis of prostate cancer may be an underlying cause in patients evaluated for solitary pulmonary nodule by FDG PET/CT.Publication Open Access Immunoexpression of TTF-1 in Non-Lung Tumors(2014-12-01T00:00:00Z) TOSUNER, ZEYNEP; ARICI, Dilek Sema; GÜCİN, ZÜHAL; BÜYÜKPINARBAŞILI, NUR; SÖNMEZ, FATMA CAVİDE; YILDIZ, PELİN; TOSUNER, ZEYNEP; ARICI, DILEK SEMA; GÜCİN, ZÜHAL; BÜYÜKPINARBAŞILI, NUR; SÖNMEZ, FATMA CAVİDE; YILDIZ, PELİNObjective: Thyroid transcription factor-1 (TTF-1) immunoexpression is frequently determined in small-cell lung carcinomas, as well as primary lung adenocarcinomas. While dealing with metastatic carcinomas, TTF-1 immunoexpression is a significant indicator of primary lung carcinomas. Recent studies have revealed that TTF-1 immunoexpression is also defined in non-lung cancers, such as squamous cell carcinomas of different sites and certain neuroendocrine tumors. The verified data obtained from these studies indicate that a straightforward diagnosis of primary lung carcinoma in cases with positive TTF-1 immunoexpression can cause diagnostic contradictions. The aim of our study is to investigate the immunoexpression status of TTF-1 in common non-lung tumors. Methods: A total of 85 cases that were diagnosed in our institute between the years 2011-2012 were included in our study. After a review of the pathological slides prepared from these tumors [colon adenocarcinoma (n: 15), renal cell carcinoma (n: 15), prostate adenocarcinoma (n: 15), invasive papillary urothelial carcinoma (n: 15), invasive ductal carcinoma of breast (n: 15), and neuroendocrine tumors (n: 10)] TTF-1 immunohistochemistry was applied. Semiquantative evaluation based on the distribution and intensity of the staining was performed by two pathologists, respectively. Results: Positive immunostaining was evident in only 1 case of colon adenocarcinoma out of 85 cases. Conclusion: Our study demonstrated that TTF-1 immunoexpression is a very rare finding (1%) in non-lung tumors. This result provides that anti-TTF-1 is a reliable antibody in the interpretation of primary lung carcinomas. In fact, further studies with a large number of cases are needed to confirm the sensitivity and specificity of TTF-1.Publication Open Access Helicobacter pylori as an Etiologic Factor in Primary Lung Carcinoma(2018-04-01T00:00:00Z) BÜYÜKPINARBAŞILI, NUR; BÜYÜKPINARBAŞILI, NURObjective: Although the importance of environmental and occupational exposure to carcinogenic agents in pulmonary carcinoma is well known, some other factors, such as familial predisposition, genetic abnormalities, and recently, the presence of Helicobacter pylori infection, are being disputed. This study focused on the relationship between pulmonary carcinoma and H. pylori infection. Methods: In total, 48 histologically verified and operated patients with pulmonary carcinoma, including 38 males and 10 females, were included; 22 of the cases were of squamous cell carcinomas and 26 were adenocarcinomas. The control group composed of 20 patients who underwent pulmonary operation for causes other than lung cancer. Adjacent non-neoplastic parenchymal and bronchial tissue examples were stained using the Giemsa stain in carcinoma cases. The pulmonary tissue-contained bronchial sections were stained in control cases. The bronchial epithelia and lumina in the Giemsa stained slides were examined for H. pylori bacilli. Results: H. pylori was found in 2 of 48 carcinoma cases. The histopathological diagnosis of these 2 cases was squamous cell carcinoma. But there wasn't any case stained for H.pylori in the control group. Conclusion: The relationship between pulmonary carcinoma and H. pylori infection had been researched through serological studies; however, conflicting evidences have been obtained. The bacterium is transmitted to the lungs via seeding and inhalation was reported to be effective directly. Chronic H. pylori infection leads to bronchial epithelial proliferation via increased gastrin level and cyclooxygenase-2. Moreover, it contributes to pulmonary carcinogenesis. In conclusion, an association between H. pylori infection and pulmonary carcinoma may be revealed by variable studies, and the underlying mechanisms can be understood.
