Chylomediastinum Following Tracheal Surgery

Fever of unknown origin (FUO) is a diagnostic challenge for the practising physician. Detailed medical history, physical examination, non-invasive laboratory tests, and radiologic examinations compose the first level in the diagnostic approach to the FUO. When a diagnosis cannot be established with these procedures, some invasive diagnostic techniques and finally exploratory laparotomy are performed. Although advanced diagnostic measures and imag-ing-guided less invasive procedures have decreased the need, laparotomy remains as a final diagnostic method for FUO cases. In this study we evaluate the role and importance of laparotomy in the diagnosis of our FUO cases. In 17 out of 126 patients (8 male, 9 female, the median age 35.8 years) hospitalized in our clinic between 1982 and 2002 with the diagnosis of FUO, the diagnosis was established by laparotomy. The diagnosis was made directly in 13 patients, and indirectly (by excluding other diseases) in 2 patients. In several FUO series, the contribution of laparotomy to the diagnosis of FUO was reported as 27-100%. This rate was found to be 88% in the present study. During laparotomy on 17 cases, tissue samples were taken from spleen, liver, intra-abdominal and mesenteric lymph nodes. Pathologic examination of these tissue samples revealed miliary tuberculosis in 4; non-Hodgkin’s lymphoma in 3; Hodgkin’s lymphoma in 3; liver tumour in 1; hairy cell leukemia in 1; peritonitis carcinomatosis in 1. In the patients with miliary tuberculosis, the liver (3) and/or spleen (2), and/or lymph node (3) revealed caseating granulomas. Laparotomy diagnosed 3 of 5 cases whose abdominal ultrasonography and computerized tomography were normal. In conclusion, although advanced diagnostic methods decreased the need for laparotomy in FUO, if non-invasive and invasive diagnostic measures fail, laparotomy may contribute to the diagnosis. The selection of the patient and the timing are important for laparotomy.     

The effects of Pilates on metabolic control and physical performance in adolescents with Type 1 diabetes mellitus

Physical activity is a substantial method in the management of children and adolescents with Type 1 diabetes mellitus but it is not considered as a treatment for diabetes. The aim of this study was to investigate the effects of Pilates exercises on metabolic control and physical performance in patients with type 1 diabetes mellitus. Thirty one sedentary patients with type 1 diabetes mellitus, ranging in age from 12 to 17 (experimental group, n=17 and control group, n=14) were submitted to 12 weeks of Pilates training. Participants underwent tests to determine the physical performance and metabolic control before and after 12 weeks of Pilates session. At the end of study, there were significant alterations in physical performance of the study group. Peak power, mean power, vertical jump and flexibility of study group increased. There were no alterations for this parameters in the control group. There was no significant difference for glycated hemoglobin (HbA1c) in both groups. Conclusions: Physical performance increased via Pilates exercises in the patients with type 1 DM. However there were no changes in metabolic control. In the present study, the positive effects of exercise on metabolic control could not be shown in patients with Type 1 DM.     

Patients with Tombstoning Pattern on the Admission Electrocardiography Who Have Undergone Primary Percutaneous Coronary Intervention for Anterior Wall ST‐Elevation Myocardial Infarction: In‐Hospital and Midterm Clinical Outcomes

Background: A tombstoning pattern (T‐pattern) is associated with in‐hospital poor outcomes patients with ST‐segment elevation myocardial infarction (STEMI), but no data are available for midterm follow‐up. We sought to determine the prognostic value of a T‐pattern on admission electrocardiography (ECG) for in‐hospital and midterm mortality in patients with anterior wall STEMI treated with primary percutaneous coronary intervention (PCI). Methods: After exclusion, 169 consecutive patients with anterior wall STEMI (mean age: 55 ± 12.9 years; 145 men) undergoing primary PCI were prospectively enrolled in this study. Patients were classified as a T‐pattern (n = 32) or non–T‐pattern (n = 137) based upon the admission ECG. Follow‐up to 6 months was performed. Results: In‐hospital mortality tended to be higher in the T‐pattern group compared with non–T‐pattern group (9.3% vs 2.1% respectively, P = 0.05). All‐cause mortality was higher in the T‐pattern group than non–T‐pattern group for 6 month (P = 0.004). After adjusting the baseline characteristics, the T‐pattern remained an independent predictor of 6‐month all‐cause mortality (odds ratio: 5.18; 95% confidence interval: 1.25–21.47, P = 0.02). Conclusion: A T‐pattern is a strong independent predictor of 6‐month all‐cause mortality in anterior STEMI treated with primary PCI. Therefore, it may be an indicator of high risk among patients with anterior wall STEMI.     

Early repeat endoscopic retrograde cholangiopancreatography: Predictive factors and interventions required

Background/aims: Early repeat endoscopic retrograde cholangiopancreatography may be required due to various conditions in patients who underwent planned endoscopic retrograde cholangiopancreatography. We aimed to assess the factors leading to early repeat endoscopic retrograde cholangiopancreatography and to determine the patients who need closer follow-up. Materials and Methods: A total of 691 patients with a mean age of 60.3±16.4 years who had naive papilla on endoscopic retrograde cholangiopancreatography were involved in the study. The patients who required repeat endoscopic retrograde cholangiopancreatography were identified. Presentations, predictive factors, treatment modalities, and outcomes of the patients were investigated. Results: Early repeat endoscopic retrograde cholangiopancreatography was needed in 19 (2.7%) patients. The most common presentation was cholangitis in 10 (52.6%) and unresolved jaundice in 4 (21.1%). Multivariate analysis identified biliary stricture (p=0.024), stricture at the hilus (p=0.005) and unilateral drainage in the presence of hilar stricture (p=0.017) as the independent risk factors for early repeat endoscopic retrograde cholangiopancreatography. Stent migration or dysfunction was the most common underlying cause. Therapeutic interventions were nasobiliary drainage in 13, stent exchange in 4 and stone removal in 2. Additionally, percutaneous drainage in 4 patients, drainage of abscess in 2 patients and percutaneous drainage of gallbladder in 1 patient were performed. Three patients died due to their underlying illness. Conclusions: Unilateral stenting especially in hilar strictures is a predictive factor for early repeat endoscopic retrograde cholangiopancreatography with high mortality. These patients should be under close follow-up.     

Fascioliasis: 3 cases with three different clinical presentations

Fascioliasis, which is a zoonotic infestation caused by the trematode Fasciola hepatica (liver fluke), is primarily a disease of herbivorous animals such as sheep and cattle. Humans become accidental hosts through ingesting uncooked aquatic plants such as watercress. It presents a wide spectrum of clinical pictures ranging from fever, eosinophilia and vague gastrointestinal symptoms in the acute phase to cholangitis, cholecystitis, biliary obstruction, extrahepatic infestation, or asymptomatic eosinophilia in the chronic phase. However, it may often be overlooked, especially in the acute phase, because of vague symptoms. As a result of newly introduced serological assays facilitating the diagnosis, there has been an increase in the number of reported cases. Here, we report the clinical and laboratory assessment and therapeutic approach of a series of three cases diagnosed (in order of) one week, three months and one and a half years after presentation of the first symptoms of the disease.     

Prevalence of Occult Hepatitis B and Hepatitis C Virus Infections in Turkish Hemodialysis Patients

Background and Objective. Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are important causes of morbidity and mortality in maintenance hemodialysis patients. Although their exact prevalence is not known, HBV and HCV viral infections and occult viral hepatitis are frequent in these patients. This study aimed to determine the prevalence of occult HBV and HCV infections in maintenance hemodialysis patients. Materials and Methods. One hundred and eighty-eight end-stage renal disease patients on maintenance hemodialysis (100 male, mean age 49±29 [16–80] years, and mean duration of hemodialysis 98±66 [12–228] months) were enrolled in this study. Serological markers for HBV and HCV were determined with immunoenzymatic assay (ELISA) by using commercial diagnostic kits (Access and BioRad, Beckman-Coulter). HCV-RNA (Cobas Amplicor HCV kit) and HBV-DNA (Artus GmbH HBV kit) were determined quantitatively by polymerase chain reaction. Results. Among the patients screened, 25 (13.3%) had HBV infection alone and 38 (20.2%) had HCV infection alone, while seven (3.7%) had dual infection of both viruses. Serological markers for occult hepatitis B and occult hepatitis C were positive in five (2.7%) and nine (4.8%) of the patients, respectively. Isolated anti-HBc was positive in 12 (6.4%) of all patients, three (7.9%) of the patients with anti-HCV and two (40%) of the patients with occult hepatitis B. Isolated anti-HBc positivity was more frequent in patients with occult hepatitis B than in those without (40% [2/5] vs. 5.5% [10/183], p=0.002). None of the patients with HCV had occult hepatitis B. Conclusions. Both occult and non-occult forms of HCV infection are more prevalent than HBV infection in hemodialysis patients. Especially the patients with isolated anti-HBc positivity should be tested for probable occult hepatitis B infection.     

Sciatic nerve compression by an extrapelvic cyst secondary to wear debris after a cementless total hip arthroplasty: A case report and literature review

INTRODUCTIONPolyethylene (PE) wear debris after total hip arthroplasty (THA) may cause formation of a soft tissue mass due to inflammatory reaction. To the best of our knowledge we report the first case in whom the diagnosis was made after examination of the hip, pelvis and lumbar spine with detailed radiological methods and the plain radiographs showed no signs of loosening of the THA.PRESENTATION OF CASEWe report a 52 years-old woman who presented with a cyst causing sciatic irritation in her gluteal region due to wear debris after THA. Magnetic resonance imaging (MRI) was useful in detecting the cyst. Resolution of the cyst occured after subtotal cystectomy and revision of the acetabular components.DISCUSSIONAlthough plain radiographs can show signs of the underlying pathology; such as osteolysis, loosening of the components and wear of the PE liner, they are unable to detect cystic lesions. Cystic lesions may be an early sign of wear debris.CONCLUSIONThis case shows us that sciatic neuropathy with no evidence of nerve root impingement on lumbar MRI in a patient with THA requires also examination of the hip and pelvis with detailed radiological methods, such as MRI, in addition to plain radiography. Removal of the source of debris via revision surgery following subtotal cystectomy leads to the resolution of the remaining portion of the cyst and also relief of the symptoms of sciatic nerve compression.
