Hemoperitoneum secondary to spontaneous rupture of metastatic gastric leiomyosarcoma of the liver: Report of a case.

Hepatic rupture with resulting hemoperitoneum due to metastatic cancer is uncommon. Reports in the literature have described a wide variety of neoplasms causing this usually fatal phenomenon. We describe a rare case of spontaneous rupture of hepatic metastases from gastric leiomyosarcoma. A 72-year-old male patient with sudden onset severe epigastric pain was rushed into emergency service. After examination, the patient underwent urgent operation withe possible diagnosis of perforated gastric or duodenal ulcer. During exploration, we determined bleeding mass on the diaphragmatic side of the left lobe of the liver and a mass on the posterior wall of the stomach. Hemostasis was provided.     

Short-term antidepressant treatment of comorbid dental anxiety in patients with panic disorder

Objectives. The aims of this study were to determine the frequency of dental anxiety (DA) and dental phobia (DP) in panic disorder, and to follow the changes in DA levels during antidepressant treatment of panic disorder. Methods. Fifty-three controls and 102 panic disorder patients were assessed using the Structured Clinical Interview (SCID), the Panic-Agoraphobia Scale (PAS), and the Corah Dental Anxiety Scale (DAS). Oral health status was defined by the number of decayed, missing, and filled teeth (DMFT) index. The patients were classified into three groups: (1) those without dental anxiety (WDA), (2) those with dental anxiety (DA), and (3) those with dental phobia (DP). All patients were treated with antidepressants for 3 months and the response rates were assessed. Results. At baseline, DAS was significantly higher in both the DA and the DP groups than in the control group. Ten (9.8%) of the panic disorder patients fulfilled the diagnostic criteria for DP; 31 (30.4%) had severe DA. In the control group, none of the patients was diagnosed as DP, whereas 7 (13.5%) had severe DA. Panic disorder and DA both responded to the antidepressant treatment, but DAS scores remained significantly higher in the DP group than in the DA group and the control group at the end of the third month. Conclusions. Our data suggest that both DA and DP are more frequent in panic disorder than in healthy controls. Antidepressant treatment may have been helpful in decreasing DA levels in the DA group but not in the DP group.

Superior vena cava thrombosis in chronic lead exposure--a case report

Thrombosis is a rare cause of superior vena cava syndrome (SVCS). A 43-year-old male patient with SVCS due to thrombosis underwent investigation for the etiology of thrombus formation. He had been hospitalized several times because of lead intoxication in the past. Lead has a known thrombogenetic effect experimentally. This patient with superior vena cava thrombosis had thrombophilia that was probably due to lead intoxication. The etiologies of venous thrombosis and thrombogenetic effect of chronic lead exposure are discussed.     

Outcome of Surgery for Lung Cancer in Young and Elderly Patients

Purpose It has been suggested that lung cancer follows a more aggressive course and has a poorer prognosis in young patients than in elderly patients. We conducted this study to determine whether the basal characteristics and survival of young patients undergoing surgical resection of lung cancer differ from those of elderly patients.Methods Eighty patients who underwent surgery for lung cancer at our hospital between 1989 and 2004 were divided into two groups according to age. Group 1 comprised 50 patients aged 45 years or younger and group 2 comprised 30 patients aged 70 years or older. The patients’ medical records were reviewed with respect to age, gender, histological diagnosis, coexisting diseases, smoking history, postoperative staging, type of operation, and postoperative morbidity, mortality, and survival results.Results The average ages were 40.2 ± 3.77 years (range, 29–45 years) in group 1 and 72.2 ± 2.53 years (range, 70–80 years) in group 2. The incidence of postoperative complications was significantly higher in group 2 (P = 0.02). However, the 5-year survival rates for patients who underwent surgery for non-small cell lung cancer did not differ between groups 1 and 2, at 33.3% versus 21.3%, respectively (P = 0.09).Conclusions The incidence of adenocarcinoma was higher in the young patients, whose prognosis was slightly better than that of the elderly patients. Coexisting diseases and postoperative complications were the major factors that adversely affected the prognosis of the elderly patients.     

Enhanced tissue factor pathway inhibitor response as a defense mechanism against ongoing local microvascular events of Legg-Calve-Perthes disease

The precise pathogenetic basis of Legg-Calve-Perthes disease (LCPD) is currently unknown. Hemostatic abnormalities, i.e., hypercoagulability and/or hypofibrinolysis, were proposed in the genesis of the LCPD. Deficiency of tissue factor pathway inhibitor (TFPI), a critical natural anticoagulant molecule, may lead to a prothrombotic state in a wide variety of conditions. The aim of this study is to assess the circulating TFPI pool in the LCPD. Group I consisted of 44 patients with LCPD and group II comprised 38 healthy children. Median (IQR) TPFI concentration was significantly higher in the group I (p < .0001). Enhanced TFPI response could be regarded as a compensatory defense mechanism against ongoing local microvascular events of occlusion and revascularization of LCPD. TFPI molecule may be an important link between the crossroads of the LCPD genesis and pathogenetic microvascular changes in the disease course. Further investigations are needed to shed light on the endothelial anticoagulant kinetics, the unique microvascular compromise, and the self-limiting nature of the disease.
