Diagnostic performance of 64-slice computed tomography coronary angiography to detect significant coronary artery stenosis

OBJECTIVE: We aimed to determine the diagnostic accuracy of 64-slice multi-slice computed tomography (MSCT) to detect significant coronary artery stenosis with comparison to conventional coronary angiography (CCA). METHODS: In 100 patients (70 men, average age 58 +/- 10 years and age range 31-75 years) scheduled to have conventional coronary angiography, MSCT was performed before catheterization (within 2 months). All patients were in sinus rhythm, able to hold breath for 15 seconds, and had serum creatinine levels < 1.5 mg/dl. MSCT scans were analysed by a radiologist and a cardiologist. Sensitivity, specificity, positive and negative predictive values for the detection of significant stenoses by MSCT in comparison with CCA were calculated on patient, vessel, and segmental bases. RESULTS: 64-slice computed tomography is able to detect significant coronary artery stenosis on a segmental basis with a sensitivity of 88% and specificity of 99% when compared with CCA. All patients with significantly stenotic coronary artery disease are correctly diagnosed. The presence of significant stenosis was correctly diagnosed by MSCT in 126 of 144 segments. Twelve non-significant lesions on CCA were overestimated by MSCT. On vessel-based analysis, the sensitivity and specificity of MSCT for detecting significant stenosis were 91% and 97%, respectively. CONCLUSION: Our results indicate that 64-slice computed coronary angiography is a reliable diagnostic modality for the detection of significant coronary artery stenosis in patients with sinus rhythm and scheduled to have CCA, but still has limitations of diagnostic performance on a per-segment and per-vessel basis.     

A randomized trial of botulinum toxin vs lidocain pomade for chronic anal fissure

PURPOSE: As lateral sphincterotomy and anal dilatation causes complications, a reversible chemical sphincterotomy method has been recently proposed as an alternative treatment in patients with anal fissure. In this study, the effect of botulinum toxin causing temporary paralysis in internal anal sphincter was compared with that of lidocaine in patients with chronic anal fissure. METHOD: A total of 62 outpatients were randomly assigned to receive botulinum toxin or lidocaine pomade. The patients were evaluated before and after two months of treatment with physical examination and anal manometry. Pain and nocturnal pain were scored. RESULTS: In an evaluation period of two months, in 24 of 34 patients of botulinum group (70.58%), and in six of 28 patients of lidocaine group (21.42%) showed complete epithelization (p = 0.006). All patients who had previously reported nocturnal pain became symptom free in botulinum group and in four patients of lidocaine group. Pain following defecation disappeared in 24 patients of botulinum group and in 20 patients of control group (p = 0.959). There was no adverse effect in both groups. While resting anal pressure and maximum voluntary pressure were significantly low in botulinum toxin group, both parameters did not change in lidocaine group. CONCLUSIONS: Botulinum toxin is a reliable and effective method for patients with chronic anal fissure. It can be applied easily without any anesthesia and instrumentation. It is cheaper in comparison with surgical methods and it can be a good alternative treatment in patients with risk of incontinence.

Carotid endarterectomy under local anesthesia: single institutional experience

The aim of this study is to review our experience and results of carotid endarterectomy performed under local anesthesia. We evaluated 300 patients who had undergone carotid endarterectomy with local anesthesia in our department. Surgical indication, outcome, operative technique, and complications were assessed. The patients were 58.20+/-2.76 years old and 153 (51%) were symptomatic. The perioperative course was uneventful. A shunt was inserted because of neurological deterioration in 20 patients (6.6%) with full recovery of the deficit after shunt insertion. Operative time was 52.02+/-12.86 min. There were 9 patients with postoperative neurological complications with one patient who died after 34 days. The remaining 8 patients with reversible neurological deficits recovered and were symptom-free on discharge. The mean length of hospital stay was 2.11+/-1.34 days. Carotid endarterectomy performed under local anesthesia is associated with low morbidity and mortality rates. The surgeon can assess the neurological status during the procedure and provide for a more meticulous endarterectomy. It is also associated with decreased shunt usage, decreased operative time and shorter length of hospital stay.     

Pregnancy under treatment of imatinib and successful labor in a patient with chronic myelogenous leukemia (CML). Outcome of discontinuation of imatinib therapy after achieving a molecular remission

Because of the teratogenicity data in rats, it is recommended that women treated with imatinib should be aware of the potential teratogenicity of imatinib and effective contraception should be used during imatinib therapy to prevent pregnancy. We describe successful pregnancy and delivery, without any congenital anomaly, in a patient with CML under treatment of imatinib. The fetus had been exposed to imatinib for 8 weeks. The patient remained off treatment during gestation and cytogenetic relapse of CML (5 months after discontinuation of imatinib therapy) developed at seventh month of gestation.
