Reversal of deep vein reflux after successful stenting in a patient with venous hypertension after thigh access graft creation

Presented here is a case of reversal of deep vein reflux after successful stenting in a patient with venous hypertension and valve incompetence after thigh angioaccess creation. The patient with exhausted upper-extremity access sites underwent a loop graft in the upper thigh. Six months later, the patient developed leg edema and significant femoral vein reflux on duplex ultrasound. Fistulography revealed an iliac vein stenosis, which was treated successfully with stenting. The edema and reflux on duplex promptly resolved. In similar cases, reflux may be a consequence of functional valve incompetence and can be reverted by timely treating the underlying stenosis.     

Endemic fluorosis in Turkish patients: relationship with knee osteoarthritis

Fluoride excess primarily effects dental and skeletal tissues. leading to a condition known as endemic fluorosis. The radiological and clinical features of endemic fluorosis vary in different parts of the world. The aim of this study was to investigate the clinical and radiological features of endemic fluorosis in Turkish patients. Physical examination and radiological investigations were performed in 56 patients with endemic fluorosis and 40 age- and sex-matched controls. Knee osteoarthritis (OA) was the main abnormality in both groups, both clinically and radiologically. The radiological severity of knee OA was greater in the endemic fluorosis group than in controls (P=0.01). Osteophytes at the tibial condyles and superior margin of the patellar articular surface of the femur, polyp-like osteophytes on the non-weight-bearing medial side of the femoral condyle, and popliteal loose bodies were detected more frequently in the endemic fluorosis group than in controls (P=0.0001). We suggest that the presence of atypically located osteophytes in the knees may be a feature of endemic fluorosis in Turkish patients and that endemic fluorosis may increase the severity of OA in the knees.     

Evaluation of hepatic functions and biliary dynamics in patients with liver cirrhosis by quantitative scintigraphy

BACKGROUND/AIMS: Aim of the study is to determine the changes in hepatocyte and gallbladder motor functions, and biliary dynamics in patients with liver cirrhosis. METHODOLOGY: The study group consisted of 17 patients with liver cirrhosis (12 males, 5 females) who were diagnosed by clinical, laboratory and histopathologic findings. Control group consisted of 20 healthy persons (14 males, 6 females). Quantitative hepatobiliary scintigraphy was performed by using Tc99m-Mebrofenin i.v. and dynamic images were obtained and evaluated quantitatively by computer. Maximum excretion time of radiodiagnostic agent by liver (Tmax) and half excretion time of radio-diagnostic agent from liver (T 1/2), gallbladder filling time, gallbladder ejection fraction and the transit time of bile to duodenum were determined. RESULTS: Mean values of Tmax was 25.76 vs. 12.40 min, T 1/2 was 37.55 vs. 23.15 min, gallbladder filling time was 53.35 vs. 30.57 min, and transit time of bile to duodenum was 39.88 vs. 25.00 min in the patients and control group, respectively. These values increased significantly in the patient group (p < 0.05) compared to controls. Mean gallbladder ejection fraction was 37.55% in the patient group and 41.84% in the control group without any statistical significance (p > 0.05). The incidence of gallbladder stone was 29.41% in the cirrhosis group and 5% in the control group (p < 0.05). CONCLUSIONS: The quantitative hepatobiliary scintigraphy is a simple and reliable method in evaluation of hepatic functions and biliary dynamics in cirrhotic patients. Although the incidence of gallbladder stone is significantly increased in cirrhotic patients, it seems that a stone in the gallbladder does not affect the gallbladder motor functions.     

Epithelioid leiomyosarcoma with rhabdoid features

Leiomyosarcomas (LMS) are the most common type of uterine sarcoma. Most LMS have typical histologic features, and variants such as epithelioid LMS, myxoid LMS, LMS with osteoclast-like giant cells and LMS with rhabdoid features occur only rarely. Rhabdoid cells were first described in rhabdoid tumor, a distinctive renal neoplasm of infancy. Such tumors are composed of diffuse proliferation of rhabdoid cells that are round or polygonal in shape with eccentric nuclei, prominent nucleoli and glassy eosinophilic cytoplasm containing hyaline-like inclusion bodies. In the literature, extrarenal localizations of malign rhabdoid tumors have been described in a variety of primary sites such as the central nervous system, liver, skin and soft tissues. These characteristic rhabdoid cells have been reported in sarcomas and carcinomas of various types and in a few cases of uterine sarcomas. The presence of rhabdoid cells in tumors is considered to be a predictor of aggressive tumor behavior. Our case is that of a 56-year-old woman who was admitted to the state hospital with left inguinal mass. Microscopically the tumor was admixed of three different types of cell with spindle, epithelioid or rhabdoid features. Immunopositive cytoplasmic staining for myoglobulin and desmin was seen in rhabdoid cells, and cytokeratin immunopositivity was observed in epithelioid and some rhabdoid cells. Epithelioid cells and spindle cells were also SMA positive. The histopathologic and immunohistochemical findings support the diagnosis of epithelioid LMS with rhabdoid features. We report this very uncommon LMS variant; to the best of our knowledge there are only a few cases in the English literature.     

Lung cancer in women: clinical features and factors related to survival

Lung cancer in women is increasing in worldwide. This process beginning with the difference on the susceptibility of lung cancer in women smokers may be different from men in the prognosis. In this study, it was aimed to evaluate the clinical features, and prognostic factors of female patients with lung cancer diagnosed between January 2000-December 2005. The data of 109 patients data was evaluated. The mean age was 59.40 +/- 11.56 and 17 (15.6%) patients were smokers. In 20 patients (18.3%) having a family history of cancer, 55% of them had a relative with lung cancer. In admission, cough (81.7%), dyspnea (78.9%), chest pain (40.3%) were the most frequent presenting symptoms. The most common site of tumoral lesion in bronchoscopy were right upper lobe (16.5%). In the study group histopathological diagnosis were as follows; adenocarcinoma (44.9%), small cell lung cancer (SCLC) (19.3%), squamous cell (10.1%), non-small cell lung cancer (NSCLC) --undefined (22.0%), carsinoid tumors (2.8%), in non-smokers adenocarcinoma was significantly higher than smokers (44.9%/17.7%) (p< 0.001). 61.9% of NSCLC patients and 57.1% of SCLC patients had a stage IV disease at the initial evaluation. The most common sites of metastasis were bone (28.4%), liver (22.9%), and brain (11.9%), there were multiple metastasis in 10 patients. Median survival time was found as 288 days. In univariate analysis, comorbidity, primary tumor stage, bone metastasis, advanced disease stage, ECOG performance score >or= 2 and supportive care alone were poor prognostic factors. In multivariate analysis, poor performance status (p= 0.003), advanced disease stage (p= 0.002) and bone metastasis (p= 0.04) were negatively related to survival. In women, the definition of the clinical features, disease course and survival related factors may contribute to our future treatment approaches based on our national data.     

Pulmonary hypertension in rheumatoid arthritis

Using Doppler echocardiography (DE), we measured pulmonary arterial systolic pressure (PASP) in rheumatoid arthritis (RA) patients without coexisting cardiopulmonary diseases. Accepting the normal upper limit of PASP as 30 mmHg, we found elevated PASP in 11 out of 40 (27.5%) RA patients, values being mostly 30-40 mmHg, indicating mild pulmonary hypertension (PHT). Although estimation of PASP by DE is not as reliable as cardiac catheterisation, it is possible that mild elevations in PASP may contribute to the high incidence of cardiovascular events not explained by traditional cardiac risk factors in patients with RA. Long-term follow-up will be obviously necessary to ascertain the impact of mild PHT on the prognosis and mortality rate of RA patients.     

A rare extraintestinal manifestation of ulcerative colitis: Tracheobronchitis associated with ulcerative colitis

We describe a 44 year-old woman who presented with dyspnea and cough 5 years after initial diagnosis of ulcerative colitis. The evaluation of patient showed findings of large airway inflammation with tracheal wall thickening and mucosal irregularities. The etiology was investigated and was diagnosed as tracheobronchitis that is a rare extraintestinal manifestation of ulcerative colitis. She was treated with systemic corticostreoids and rapid clinical improvement was detected.
