(Pergamon-elsevier Science Ltd, 2007) Temizoz, Osman; Etlik, Omer; Sakarya, Mehmet Emin; Uzun, Kursat; Arslan, Halil; Harman, Mustafa; Demir, Mustafa Kemal
We aimed to determine the degree and extent of parenchymal abnormalities on pulmo-CT in patients with emphysema. The study group consisted of 29 patients (18 male, I I female; mean age 57.9. L 13). The diagnosis was based on clinical symptoms, pulmonary function tests (PFT) values, and chest CT findings. All of the patients CT scans were obtained during suspended deep inspiration from the apices to the costophrenic angles. The mean lung attenuation (MLD) and parenchymal abnormalities related to emphysema were quantitatively calculated with tables, histograms and graphics at the whole lung. The lung density measurements revealed a mean density of -898.48 +/- 51.37 HU in patients with emphysema and -825.1 +/- 25.5 HU in control group. In addition, mean percentage of subthreshold attenuation values was found as 12.03 +/- 15.75 and 1.07 +/- 0.83 in patients with emphysema and control group, respectively. Compared with control group, the patients with emphysema had a significantly lower inspiratory MLD (p < 0.05). Additionally, statistically significant correlations were seen between the MLD and percentage of subthreshold values (r = 0.44, p < 0.05). In contrast, there was poor correlation between PFT measurements and the subthreshold values. In conclusion, pulmo-CT is a quick, simple method for quantitative confirmation of the presence of parenchymal abnormalities of lung as mosaic attenuation and should be used in combination with other radiological methods and PFT as it gives additional information to routine examinations in patients with emphysema.

Internal Jugular Vein Thrombosis Two Different Etiologies
(Modestum Ltd, 2005) Erkoc, Reha; Uzun, Kursat; Yuca, Koksal; Etlik, Omer; Dogan, Ekrem; Sayarlioglu, Hayriye; Cankaya, Hakan
Internal Jugular vein (IJV) thrombosis is a rare entity. It is usually secondary to various etiologies such as catheter, malignancy, trauma, infection and hypercoagulable status. Associated malignancies, either known or occult, are also uncommon and not well documented in the etiology of IJV thrombosis. We reported IJV thrombosis with two different pathologies i.e. malignacy and congestive heart failure. The diagnosis of IJV thrombosis was established with Doppler ultrasound and CT scan. These patients were treated low-molecular-weight heparin and oral anticoagulation. Early diagnosis and appropriate management is important to prevent potentially fatal complications from internal jugular vein thrombosis.
A Rare Complication of Internal Jugular Vein Cannulation: Horner's Syndrome
(Modestum Ltd, 2005) Dogan, Ekrem; Erkoc, Reha; Sayarlioglu, Hayriye; Etlik, Omer; Uzun, Kursat
Internal jugular vein cannulation has become the preferred approach for temporary vascular access for hemodialysis. Internal jugular vein cannulation is associated with a high rate of successful catheter placement. However, significant complications such as internal carotid artery (ICA) puncture, vessel erosion, thrombosis and infection can occur. We present one case of Horner's syndrome (without arterial punction) occurring following internal jugular venous cannulation. We suggested that, clinicians need to be aware of the risk of Horner's syndrome as a possible complication of percutaneous hemodialysis catheterization via the internal jugular vein and should avoid repeated manipulations
Rheumatoid Arthritis and Pulmonary Carcinoid Tumor
(Modestum Ltd, 2005) Sayarlioglu, Mehmet; Izmirli, Mustafa; Uzun, Kursat; Alici, Suleyman; Erkoc, Reha
A 40-yearold woman was admitted with a history of elbow, wrist, knee pain and prolonged morning stiffness. Rheumatoid arthritis (RA) diagnosed before five years, had been treated with non-steroidal anti-inflammatory agents and low dose corticosteroid. On hospital admission, routine chest x-ray showed a 4x4 cm solitary mass in the right pulmonary. A diagnostic thoracotomy was performed. The histological examination showed a typical carcinoid tumor. This is the third carcinoid tumor case reported to be associated with RA.
