Spontaneous haemorrhage in a cerebellar abscess: a unique complication

A case of spontaneous haemorrhage in a cerebellar abscess is reported. Only two reports of this complication have been found in the literature. An incidental acoustic schwannoma was also found close to the abscess.     

Multiple neurological lesions due to vertebrobasilar dolichoectasia

Four cases which presented with multiple neurological signs caused by vertebrobasilar dolichoectasia are reported. The pathology was revealed by CT, MRI and angiograms. In one case, hemifacial spasm and other neurological deficits were cured by microvascular facial nerve decompression. The literature on the subject is reviewed.     

Designing a complete-arch digital trial tooth arrangement for completely edentulous patients by using an open-source CAD software program: A dental technique

A method for creating a complete-arch digital trial tooth arrangement for completely edentulous patients is described. The technique demonstrates an effective way to reproduce the dental and gingival anatomies by using a free 3D modeling software program. This cost-effective, time-saving, and versatile method allows dental professionals to digitally plan challenging treatments for completely edentulous patients. The technique can also be used to fabricate diagnostic prostheses and implant-supported interim prostheses.     

Faculty and resident preference for two different forms of lecture evaluation

OBJECTIVE: This study was undertaken to compare the use of 2 different lecture evaluation forms developed for obstetrics and gynecology residents to evaluate core curriculum lectures given by faculty. STUDY DESIGN: Content and delivery of faculty lectures were evaluated by residents using (1) a 10-question evaluation form that used a 5-point rating scale and (2) a checklist evaluation form that offered multiple options to improve lectures but provided no numerical score. Each form was used exclusively for 4 months. Faculty received feedback from both forms; then faculty and residents were surveyed regarding their preferences. RESULTS: A total of 384 rating scale and 398 checklist evaluation forms were completed during the study period. Residents preferred to complete the rating scale evaluation forms (67%), whereas faculty preferred feedback from the checklist evaluation forms (62%). Faculty were more likely to plan changes to their lecture format with feedback from the checklist evaluation forms (75% vs 25%, P = .031). CONCLUSION: Although devoid of structured positive feedback, the checklist lecture evaluation form was preferred by faculty.     

Passage of tube per rectum: an unusual complication of a ventriculoperitoneal shunt

A very rare complication of a ventriculoperitoneal (VP) shunt is reported. The peritoneal catheter perforated the colon of a two-year-old child, causing diarrhoea which was misdiagnosed as gastroenteritis. The diagnosis became obvious when the catheter was extruded from the child's anus.     

High resolution spiral CT scan in the diagnosis of pseudoaneurysm of ascending aorta

Pseudoaneurysms of the ascending aorta are rare (<1%), and extremely rare from aortic vent site, but can be a lifethreatening complication. The basic methods of diagnosis are computed tomography scan and aortography. We report high resolution spiral CT may provide the best less invasive means in the diagnosis of the pseudoaneurysm of the ascending aorta originated from the aortic vent site.
