Two cases of Wegener's granulomatosis with pancreatic pseudocyst treated by endoscopic ultrasonography (EUS)-guided drainage.

Wegener's granulomatosis is a systemic vasculitis with prominent involvement of the respiratory tract and kidney. There are 10 patients with Wegener's granulomatosis in the literature who were documented as acute pancreatitis. We present two cases with Wegener's granulomatosis presenting with acute pancreatitis and pancreatic pseudocyst. Endosonography-guided drainage of the pancreatic pseudocyst led to rapid clinical improvement. Pancreatic pseudocyst in Wegener's granulomatosis is not reported in the literature, and these are the first cases of Wegener's granulomatosis to be managed by endosonography-guided cyst drainage. The safety of endosonography-guided pancreatic pseudocyst drainage and the clinical features of the previous Wegener's granulomatosis cases with acute pancreatitis are discussed.

Comparison of methods for detection of Blastocystis infection in routinely submitted stool samples, and also in IBS/IBD Patients in Ankara, Turkey.

BACKGROUND: This study compared diagnostic methods for identifying Blastocystis in stool samples, and evaluated the frequency of detection of Blastocystis in patients with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). RESULTS AND DISCUSSION: From a set of 105 stool specimens submitted for routine parasitological analysis, 30 were identified as positive for Blastocystis by the culture method. From that group of 30 positives, Lugol's stain, trichrome staining, and an immunofluorescence assay identified 11, 15, and 26 samples as positive respectively. Using culture as a standard, the sensitivity of Lugol's stain was 36.7%, trichrome staining was 50%, and the IFA stain was 86.7%. The specificity of Lugol's stain was 91%, trichrome staining was 100%, and the IFA stain was 97.3%. In the group of 27 IBS and IBD patients, using all methods combined, we detected Blastocystis in 67% (18/27) of the patients. Blastocystis was detected in 33% (2/6) of IBD patients and 76% (16/21) of IBS patients. For comparison, trichrome staining alone, the method most frequently used in many countries, would have only identified Blastocystis infection in 29% (6/21) of the IBS patients. No parasitic co-infections were identified in the IBS/IBD patients. Most Blastocystis-positive IBS/IBD patients were over 36 with an average length of illness of 4.9 years. CONCLUSIONS: Most IBS patients in this study were infected with Blastocystis. IFA staining may be a useful alternative to stool culture, especially if stool specimens have been chemically preserved.

Evaluation of 2407 fetuses in a Turkish population.

OBJECTIVES: Congenital anomalies and intrauterine fetal death (IUFD) are frequent problems in pregnancies. Detection of the etiology is important for genetic counseling, and presenting the geographic distribution of the causes of disorders is necessary for a national policy on precautions. Here, we report the findings of terminated fetuses due to IUFD and congenital anomalies in Turkish population. METHODS: Physical examinations of fetuses and genetic evaluations of families were done. X-ray studies and autopsy were done in the event of necessity. Findings of these studies were combined with prenatal ultrasound results. All cases were classified according to ICD-10. RESULTS: The number of fetuses examined was 2407. Out of these, 1268 fetuses had congenital anomalies. Neurologic anomalies and musculoskeletal system malformations were the most frequent disorders. Specific diagnoses were possible in 64% of all multiple malformation syndromes. Abnormal findings were detected in 18.8% of IUFD fetuses. Nine percent had congenital anomalies and 5.2% had cord complications. The percentage of twins and triplets was 7.5% and 13% of them had anomalies. CONCLUSION: Postmortem evaluation is useful to detect findings necessary for genetic counseling. Our protocol is effective especially in fetuses with congenital anomalies but it can detect only some of the fetal reasons in IUFD cases. A more detailed protocol is needed to investigate IUFD cases.

Postmortem evaluation of 220 prenatally diagnosed fetuses with neural tube defects: detection of associated anomalies in a Turkish population.

OBJECTIVES: The aim of this study is to represent the distribution of disorders resulting from neural tube defects (NTDs). MATERIALS AND METHODS: This study was conducted on 220 prenatally diagnosed cases with NTDs. Fetuses were evaluated by physical examination, anthropometric measurements, X-rays, and photographs after termination of pregnancy. Chromosome analysis and autopsy were performed for 37 fetuses (16.8%) with additional malformations. RESULTS: In 29 out of 37 fetuses (78.4%), additional malformations were detected by prenatal ultrasonography, whereas in eight cases postmortem evaluation produced additional findings that were not detected prenatally. Fourteen of 37 (37.8%) and 65 of 220 (29.5%) fetuses had clubfoot, which was mostly secondary to NTDs. There was no difference in sex distribution between isolated NTDs and the group with additional abnormalities and among the groups anencephaly and anencephaly + anomaly, encephalocele and encephalocele + anomaly, spina bifida and spina bifida + anomaly. There was only one case, a female fetus, with iniencephaly in this group. Anencephaly was more frequent in cases with isolated NTDs (48.1%) than in those with additional anomalies (27%). There was no difference for other groups of NTDs. The most frequent disorder was vertebral segmentation defects, which were detected in 11 out of 37 cases (29.7%). CONCLUSIONS: Evaluation of associated malformations and confirmation of ultrasound findings can be performed by postmortem examination and simple X-ray studies for exact diagnosis, which strongly affects decisions on further pregnancies as well as genetic counseling. This method is straightforward, inexpensive and effective.

Ifosfamide, mesna, and interferon-alpha2A combination chemoimmunotherapy in malignant mesothelioma: results of a single center in central anatolia.

Our aim was to determine the efficacy of ifosfamide, mesna, and interferon alpha combination therapy in malignant mesothelioma (MM) patients. Fourty-two patients (39 evaluable) with histologically proven MM were enrolled into this study from January 1999 to October 2002. The drug schedule consisted of a combination of ifosfamide, 3000 mg/m2 1-3 d intravenous infusion (iv), the uroprotective agent mesna, 3000 mg/m2 1-3 d iv every 3 wk, and interferon alpha2a, 4.5 MU subcutaneously (sc) 3 d/wk for 6 mo as first-line chemotherapy. Overall, 140 cycles were administered to the 39 patients (median, 3.5 cycles; range, 1 to 6 cycles). Among the 39 patients, 8 partial remissions (PR) (21%) were observed. Thirteen patients (33%) had stable disease for at least 8 wk and 18 (46%) had progressive disease. Overall survival (OAS) and progression free survival (PFS) for all patients were 10.0 +/- 2.9 mo (95%CI 4.3-15.7) and 5.0 +/- 1.9 mo (95%CI 1.38-8.62), respectively. One and two year survival rates were calculated as 39% and 5%, respectively. All of the PR patients had the epithelial type of MM. Their survival time was 21.0 +/- 5.7 mo (95% CI 9.9-32.1) and significantly longer than that of nonresponders (p=0.0061). The toxicity of the drug combination was mild and well tolerated. There were no treatment-related deaths. Grade 3-4 neutropenia and febrile neutropenia were seen in 10 patients (26%) and 3 patients (8%), respectively. Chemotherapy was stopped in three patients because of renal function deficiency. One of these patients who had peritoneal MM required hemodialysis. In conclusion, this combination therapy showed encouraging antitumor activity with modest toxicity.

Cardiac troponins T and I in patients with end-stage renal disease: the relation with left ventricular mass and their prognostic value.

BACKGROUND: Cardiac troponins are frequently elevated in patients with end-stage renal disease (ESRD) in the absence of acute myocardial ischemia. The cause and prognostic value of cardiac troponin elevations in such patients are controversial. HYPOTHESIS: The aims of this study were (1) to define the incidence of cTnT and cTnI elevations in patients with ESRD, (2) to evaluate the relationship between troponin elevations and left ventricular mass index (LVMI), and (3) to evaluate the prognostic value of elevations in cTnT and cTnI prospectively. METHODS: We included 129 patients with ESRD (71 men, age 44 +/- 16 years) with no clinical evidence of coronary artery disease. All patients underwent cardiac examinations, including medical history, physical examination, electrocardiogram, and transthoracic echocardiography. Left ventricular mass index was calculated and all patients were followed for 2 years. RESULTS: The cTnT concentration was > 0.03-0.1 ng/ml in 27 (20.9%) and > 0.1 ng/ml in 27 (20.9%) of the 129 patients. The cTnI concentration was > 0.5 ng/ml in 31 (24%) of 129 patients. Multiple logistic regression analysis identified LVMI (p < 0.001), diabetes (p = 0.001), and serum albumin level (p = 0.009) as a significant independent predictor for elevated cTnT. Left ventricular mass index was the only significant independent predictor for elevated cTnI (p = 0.002). There were 25 (19.4%) deaths during follow-up. Multivariable analysis showed that elevation of cTnT and cTnI did not emerge as an independent predictor for death. Serum albumin level (p < 0.001) was the strongest predictor of mortality, followed by age (p = 0.002) and LVMI (p = 0.005). CONCLUSIONS: Cardiac troponin T and I related significantly to the LVMI. The increased serum concentration of cardiac troponins probably originates from the heart; however, they are not independent predictors for prognosis.
