Öğe Agenesis of the right lung presenting as a pulmonary infection(W B Saunders Co Ltd, 2002) Nazaroglu, H; Mete, A; Bükte, Y; Simsek, M[Abstract Not Available]Öğe Bilateral subclavian arterial aneurysm and ruptured abdominal aorta pseudoaneurysm in Behcet's disease(Springer-Verlag, 2002) Çakir, Ö; Eren, N; Ülkü, R; Nazaroglu, HBehcet's disease is characterized by recurrent ulcers of the mouth and genitalia and relapsing iritis. It is recognized as a chronic multisystem disease affecting the skin, mucous membranes, eye, joints, central nervous system, and blood vessels. About 8% of the patients with Behcet's disease have severe vascular complications such as arterial aneurysm and occlusion. In our patient, there was a massive, painful, pulsatile mass on the clavicle on the right side of neck. A left subclavian artery aneurysm mass was observed on the left apex on a chest X-ray. Through angiography, a lobular giant saccular aneurysm on the proximal side of the right subclavian artery, giant aneurysm on the left subclavian artery, and occlusion on the left subclavian-axillary artery were observed. We treated first the right and then the left subclavian arterial aneurysm with a two-stage operation. The aneurysms were resected and polytetrafluoroethylene (PTFE) graft interposition was performed. Control angiography was performed 6 months postoperatively. Both grafts were open and there was no anastomotic aneurysm. The patient was reoperated on for a ruptured abdominal aorta pseudoaneurysm 13 months after the first operation. The aortic defect was repaired using a Dacron patch.Öğe A case of multiple chondrosarcomas secondary to severe multiple symmetrical enchondromatosis (Ollier's disease) at an early age(W B Saunders Co Ltd, 2005) Bütke, Y; Necmioglu, S; Nazaroglu, H; Kilinc, N; Yilmaz, F[Abstract Not Available]Öğe Cerebral hydatid disease(E M H Swiss Medical Publishers Ltd, 2004) Biikte, Y; Kemanoglu, S; Nazaroglu, H; Özkan, Ü; Ceviz, A; Simsek, MObjective: Cerebral hydatid disease is very rare, representing only 2% of all cerebral space occupying lesions even in the countries where the disease is endemic. The aim of this paper is to describe the characteristic features of cerebral hydatid disease in computed tomography (CT) and magnetic resonance imaging (MRI). Methods: We retrospectively reviewed the CT and MR imaging findings of 18 patients with pathologically confirmed cerebral hydatid disease over a period of 13 years (1990-2002). Results: The study group consisted of 17 cases of Echinococcus granulosus and 1 case of Echinococcus multilocularis (alveolaris). They were 12 male (66.7%), and 6 female patients (33.3%), ages ranging from 7 to 50 years with an average age of 20.3 years. Headache, vomiting and seizures were the predominant symptoms. Papilloedema was present in 14 patients (77.7%). Common CT and MR imaging findings of E. granulosus lesions were well-defined, smooth thin-walled, spherical, homogeneous cystic lesions with no contrast enhancement, no calcification, and no surrounding oedema. The lesion seen with E. multilocularis was a well-defined multiseptated mass consisting of solid and cystic components with calcification in the solid portion. Cystic lesions with surrounding hyperintensity of perifocal oedema with complete or incomplete rim enhancement were seen in two patients, and were labeled as complicated and infected cysts. Conclusion: Although cystic cerebral hydatid disease is well demonstrated by CT and MR examinations, CT is superior in detecting calcification in the cyst, when present, MR is better in demonstrating cyst capsule, detecting multiplicity and defining the anatomic relationship of the lesion with the adjacent structures, and it is more helpful in surgical planning.Öğe Color doppler imaging of ocular hemodynamic changes in Behcet's disease(Elsevier Science Inc, 2004) Çaça, I; Nazaroglu, H; Ünlü, K; Cakmak, SS; Ari, S; Sakalar, YBPurpose: A prospective evaluation of the Ocular blood flow velocity in patients with Behcet's disease was carried out to determine its changes. Methods: Subjects were divided into three groups: those with ocular involvement in Behcet's disease (goup I), those without ocular involvement in Behcet's disease (goup II), and a control group (group III). Twenty-seven eyes in group I and 28 eyes each in groups II and III were investigated. The blood flow in the central retinal artery (CRA), ophthalmic artery (OA), nasal posterior ciliary artery (NPCA), and the temporal posterior ciliary artery (TPCA) was measured using color Doppler ultrasonography (CDU) to determine the peak systolic velocity (PSV), end diastolic velocity (EDV), and resistivity index (RI). The mean blood flow velocity of the central retinal vein (CRV) was also measured. These results were then compared among the three groups of subjects. Results: The PSV values of CRA in groups I and II were found to he significantly lower than those in the control group (P < 0.001, P = 0.018, respectively). The PSV values of CRA in group I were found to be significantly lower than those in group II (P < 0.001). The EDV values of CRA in groups I and II were found to be significantly lower than those in the control group (P < 0.001, P = 0.034, respectively). The EDV values of CRA in group I were significantly lower than those in group II (P = 0.041).The PSV values of OA in group I were significantly lower than those in the control group (P = 0.002). The EDV values of OA in group I were significantly lower than those values in group II or the control group (P = 0.001 and P = 0.037. respectively).The PSV values of NPCA in group I were significantly lower than those ill the control group (P = 0.007). The PSV Values of TPCA in groups I and II were significantly lower than those ill the control group (P < 0.001. P < 0.001. respectively). The EDV values of TPCA in group I were significantly lower than those values in group II or the control group (P = 0.014 and P = 0.003, respectively). There were no significant differences in the mean blood flow values of the CRV among all three groups (P > 0.05). Conclusions: There are significant reductions in the blood flow values of the orbital arteries in patients with Behcet's disease, and they are more evident in those with ocular involvement. This might be the result of occlusive vasculitis, which is frequently seen in the retinal vessels of patients with Behcet's disease.

The least common site being the mastoid process. We present one case of primary mastoid cholesteatoma confirmed by clinical examination, surgical findings and radiological evaluation.Öğe Effects of extracorporeal shock-wave lithotripsy on intrarenal resistive index(Taylor & Francis As, 2003) Nazaroglu, H; Akay, AF; Bükte, Y; Sahin, H; Akkus, Z; Bilici, AObjective: This prospective study was performed to determine whether extracorporeal shock-wave lithotripsy (ESWL), widely used for treating renal and ureteral stones, affects the kidney interlobar artery resistive index (RI). Material and Methods: A total of 43 patients (30 with renal and 13 with ureteral stones) underwent color Doppler examination before and 30 min and 3 h after ESWL. Seventeen patients with renal and nine with ureteral stones underwent Doppler examination 2 weeks later. Measurements were made near the stones (nearby region), at least 2 cm from the stones (remote region) and in the contralateral kidney for renal stones, and in the ipsilateral and contralateral kidneys for ureteral stones. Results: In patients with renal stones, the RI was increased 30 min and 3 h after ESWL in the nearby and remote regions, and more markedly in the former. In the contralateral kidney, there was an increase in RI only at 3 h, which was less than that in the ipsilateral kidney. The RI at 2 weeks post-ESWL in the nearby region and contralateral kidney did not differ from the pre-ESWL values. ESWL performed for ureteral stones caused no increase in RI in the ipsilateral kidney. Conclusion: Patients with renal stones had a temporary increase in RI in the hours following ESWL in both the ipsilateral and contralateral kidneys, which was highest in the region near the stones and lowest in the contralateral kidney. Two weeks later, the RI in both areas had returned to pre-ESWL levels.Öğe Giant intrathoracic extrapulmonary hydatid cyst manifested as unilateral pectus carinatum(Southern Medical Assn, 2002) Nazaroglu, H; Balci, A; Bükte, Y; Simsek, MLiver and lung are the most common sites of hydatid disease, but it can also be seen elsewhere in the body. Extrapulmonary intrathoracic location of the disease is rare. This case of giant intrathoracic extrapulmonary hydatid cyst manifested as unilateral pectus carinatum serves to illustrate that hydatid disease can produce various symptoms and that it may also exist in locations apart from lung and liver.Öğe Laryngopyocele(Elsevier Sci Ireland Ltd, 2000) Nazaroglu, H; Özates, M; Uyar, A; Deger, E; Simsek, MA laryngocele is an air-filled dilation of the saccule of the larynx. An infected laryngocele is called a laryngopyocele. Our experience with a case of laryngopyocele with signs on computed tomography before and after antibiotic therapy is presented since laryngopyocele is more unusual.

The aim of this study was to evaluate the computed tomography (CT) features of MPM in patients with a history of asbestos exposure. Methods: The CT scans of 117 patients who had a diagnosis of MPM were retrospectively evaluated. Additionally, CT findings of histologic subtypes were compared. Results: The most common CT findings included pleural effusion (n = 104, 89%), pleural thickening (n = 96, 82%), mediastinal pleural involvement (n = 77, 66%) and interlobar fissural involvement (n = 62, 53%). Histologic subtype analysis was performed in 89 patients; of these, epithelial, sarcomatous and mixed types were identified in 46, 23 and 20 patients, respectively. An analysis of CT findings demonstrated that the involvement of mediastinal pleural (91%), interlobar fissure (87%) and lung parenchyma (48%) was significantly more frequent in sarcomatous type, as compared to epithelial (61% and p < 0.01; 35 and 4%, p < 0.0001, respectively) and mixed types (65% and p < 0.05; 10% and p < 0.0001; 10% and p < 0.01, respectively). Furthermore, there was a significant correlation between pericardial involvement and chest walt involvement (r = 0.42, p < 0.05) in sarcomatous type. Similarly, lymphadenopathy and parenchymal involvement (r = 0.23, p < 0.02), pericardial and chest wall involvement (r = 0.25, p < 0.01), chest wall and interlobar fissural involvement (r = 0.25, p < 0.01) were significantly correlated, when CT findings of all histologic subtypes were combined. Conclusions:These results suggest that although CT findings of MPM vary, they may provide valuable clues to the diagnosis, at least in patients with a history of asbestos exposure. In addition, the presence of extensive lesions may suggest MPM of sarcomatous subtype. Copyright (C) 2000 S. Karger AG, Basel.Öğe MR angiography in diagnosis of aberrant right subclavian artery associated with common carotid trunk(Springer-Verlag, 2000) Özates, M; Nazaroglu, H; Uyar, A[Abstract Not Available]Öğe Multilocular cerebral hydatid disease with extracalvarial extension(Amer Roentgen Ray Soc, 1999) Nazaroglu, H; Özates, M; Bilici, A; Simsek, M[Abstract Not Available]Öğe Partial lipodystrophy with hemithoracic atrophy(Blackwell Science Ltd, 2000) Akdeniz, S; Harman, M; Yaldiz, M; Nazaroglu, H; Gür, A[Abstract Not Available]Öğe Pulmonary alveolar microlithiasis(Karger, 2001) Senyigit, A; Yaramis, A; Gürkan, F; Kirbas, G; Büyükbayram, H; Nazaroglu, H; Alp, MNPulmonary alveolar microlithiasis (PAM) is a lung disease characterized by deposits of calcium within the alveoli. Our aim was to emphasize the familial character and the clinical features of the disease, and to draw attention to the increasing number of Turkish patients reported in the world. We detected 6 cases of PAM. Three cases had been diagnosed 4 years earlier, and 3 new cases were detected during the screening of the family members. All patients were male and the mean age was 11.5 ranging between 5 and 29 years. Five of the patients were cousins and the other one was their uncle. Radiographic studies showed a sand-like appearance in all patients. One case showed small subpleural bullae and bronchiectatic changes in both lower robes in recent high-resolution CT scans, while his CT performed 4 years ago showed only sand-like appearance. The cases were diagnosed with the demonstration of microliths by bronchoalveolar lavage in 5 patients and transbronchial biopsy in 1. Recently reported cases from Turkey have constituted a considerable percentage among all cases in the world. In conclusion, (1) our patients constitute one of the largest series of cases reported in one family in the world. The disease seems to have familial and racial characteristics. The Turkish race has to be further investigated for genetic transmission. (2) Contrary to female predominance in previous reports, all 6 cases were male and 5 of them were below 12 years of age. (3) The disorder may show rapid progression in some cases probably due to the severity of the genetic disturbance. Copyright (C) 2001 S. Karger AG, Basel.Öğe Schwannoma of the larynx(Springer-Verlag, 2000) Meriç, F; Arslan, A; Cüreoglu, S; Nazaroglu, HNeurogenous tumours of the larynx are extremely uncommon. We present a rare case of schwannoma of the larynx. Clinical findings are presented together with computed tomography (CT) and magnetic resonance images. The tumour was located in the right aryepiglottic fold of the larynx. CT showed a well defined and hypodense mass extending from the right aryepiglottic fold to the right vocal cord. The patient underwent an excision of the mass through a lateral thyrotomy and the tumour was completely removed. The diagnosis and treatment of this tumour are discussed.Öğe Visceral leishmaniasis with multiple nodular lesions of the liver and spleen(Springer-Verlag, 2004) Bükte, Y; Nazaroglu, H; Mete, A; Yilmaz, FVisceral leishmaniasis is a severe disease caused by the intracellular protozoa Leishmania donovani. Diagnosis is based on examination of bone marrow or serology. The role of imaging techniques as diagnostic tools remains to be established in visceral leishmaniasis. We report multiple nodular lesions in the liver and spleen on ultrasonography and computed tomography in a patient with visceral leishmaniasis. To our knowledge, this is the first reported case of multiple nodular hepatosplenic lesions in visceral leishmaniasis.
