Comparison of radiological and morphologic assessments of myocardial bridges.

In this study we aimed to compare the findings of coronary dual-source computed tomography angiography of myocardial bridges with cadaveric dissections. Forty-one isolated, non-damaged fresh sheep hearts were used in this study. Myocardial bridges of the anterior interventricular branch of the left coronary artery were demonstrated and analyzed by a coronary dual-source computed tomography angiography. Dissections along the left anterior interventricular branch of the left coronary artery were performed by using Zeiss OPMI pico microscope and the length of the bridges were measured. The depths of the myocardial bridges were measured from the stained sections by using the light microscope (Leica DM 6000B). MBs were found in all 41 hearts (100%) during dissections. Dual-source computed tomography angiography successfully detected 87.8% (36 of the 41 hearts) of the myocardial bridges measured on left anterior interventricular branch of left coronary artery. The lengths of the myocardial bridges were found 5-40 and 8-50 mm with dissection and dual-source computed tomography angiography, respectively. And the depths were found 0.7-4.5 mm by dual-source computed tomography angiography and 0.745-4.632 mm morphologically. Comparison of the mean values of the lengths showed statistically significantly higher values (22.0 ± 8.5, 17.7 ± 7.7 mm, p = 0.003) for the dissections. Radiological assessment also effectively discriminated complete bridges from incomplete ones. Our study showed that coronary computed tomography angiography is reliable in evaluating the presence and depth of myocardial bridges.

Alterations of the anterior lens capsule in vitrectomized eyes with silicone oil tamponade.

BACKGROUND AND OBJECTIVE: To investigate the electron microscopic findings of the anterior lens capsule in vitrectomized eyes with silicone oil tamponade. PATIENTS AND METHODS: Ten eyes of 10 consecutive patients aged 39 to 74 years who had cataract surgery combined with silicone oil removal from December 2006 to May 2009 were included in the study. The control group included 10 patients with cataract extraction and intraocular lens implantation without history of systemic or other ocular disease. All anterior capsules underwent electron microscopic examination of the anterior lens capsule. RESULTS: During the capsulorhexis, the anterior lens capsule was removed. In the silicone oil tamponade group, silicone oil droplets were detected on the posterior surface of the anterior lens capsule in 5 cases (50%) and surface irregularities, pits, and depressions were present in the posterior surface of the anterior lens capsules in all cases. CONCLUSION: Silicone oil droplets may infiltrate the lens capsule, especially in diabetic patients. Surface irregularities may be associated with posterior fibrous pseudometaplasia produced by lens epithelial cells under the anterior lens capsule.

Diagnosis and treatment of multiseptate gallbladder with recurrent abdominal pain.

Laparoscopic cholecystectomy is usually performed for gallstones or polyp of the gallbladder. Multiseptate gallbladder is a rare congenital malformation. Although several asymptomatic cases have been described, patient usually present with right upper abdominal pain. We present a 29-year-old female patient with multiseptate gallbladder, cholecystectomy was performed, and her abdominal pain and gastrointestinal complaints have resolved.

Rapid recovery of visual acuity after lumboperitoneal shunt operation in malignant idiopathic intracranial hypertension.

Background. Idiopathic intracranial hypertension can cause rapid deterioration of visual acuity in some severe cases, and these cases are usually thought to have "malignant" form of this disease. Case. In this paper, we report on a 16-year-old girl who is a typical example for malignant idiopathic intracranial hypertension with a rapid recovery of visual acuity after lumboperitoneal shunt operation. Observations and Conclusions. Malignant form of idiopathic intracranial hypertension must be kept in mind in selected patients to avoid irreversible visual loss.
