Nasal dermoids: the significance of a midline punctum

Nasal dermoids are rare and their diagnosis is often delayed until complications occur. Signs such as a midline nasal punctum may be noted at birth but the significance of this finding frequently passes unrecognised. The cases are reported of two patients which illustrate the typical presentation of these lesions and their subsequent management is discussed.     

Low grade fibromyxoid sarcoma of the falciform ligament: a case report

Background  

Low grade fibromyxoid sarcomas (LGFMS) are very rarely seen. They commonly arise from deep soft tissues of the lower extremities. Very few cases of intra-abdominal location have been reported.     

PATIENT SATISFACTION IN PROSTHETIC REHABILITATION PROGRAMME

Patient satisfaction is an important outcome measure independent of other outcomes. Its measurement is important to assess the effectiveness of a programme and to gain insight into the patients'' perception of the programme. In this study conducted in a large rehabilitation centre it was found that majority of patients express satisfaction with care inspite of perceived discomfort. Various demographic factors, severity or duration of the disability or the level of rehabilitation do not influence patient satisfaction. Patients express more concern with aspects such as delay in issue of the prosthesis, or hotel component of the hospital services. Patients did not appear too concerned about the level of information provided. Patient satisfaction is an individual reaction to the overall care process and is influenced by the initial expectation level of the patient. Emotional response of the patient appears to be more important determinant of patient satisfaction than the cognitive evaluation. Periodical assessment of patient satisfaction should be an important component of any programme evaluation exercise.KEY WORDS: Amputation, Patient satisfaction, Programme evaluation, Prosthesis, Quality of care, Rehabilitation     

ENDOTHELIAL CELL CULTURE AND SEEDING OF PROSTHETIC VASCULAR GRAFTS: AN EXPERIMENTAL STUDY

Current synthetic vascular prostheses do not acquire lining of vascular endothelium in humans or dogs. Endothelial seeding of vascular grafts has been proposed as a means of reducing the thrombogenicity of these grafts. We examined feasibility of cultivating endothelial cells (EC) by tissue culture technique and their subsequent seeding onto small diameter polytetra fluoroethylene (PTFE) grafts. Twenty adult dogs underwent common carotid artery interposition with 4 mm PTFE grafts. Ten dogs received seeded and the remaining ten received unseeded grafts. Grafts were removed at 4 and 12 weeks and their gross/morphological features compared. Cumulative patency rates for seeded grafts were 70% as compared to unseeded ones 30%. Seeded grafts were completely surfaced with a mono-layer of endothelium by 4 weeks. Small graft patency appears to be related to the establishment of an endothelial surface, the development of which is clearly facilitated by seeding with autogenous endothelium.KEY WORDS: Endothelial cell seeding, Vascular grafts

Retrospective Study on Efficacy of Intermaxillary Fixation Screws

Background

We evaluated the efficacy of intermaxillary fixation (IMF) screws in the treatment of mandibular fractures.

Methods

Two hundred patients with mandibular fractures, treated by IMF using these screws, were evaluated by pre and postoperative panoramic radiographs. Clinical testing was carried out for vitality and abnormal mobility of teeth adjacent to the site of screw insertions. Other factors such as possible iatrogenic dental injuries, loss, breakage or screw cover by oral mucosa and postoperative occlusion were also studied.

Result

The most important complication noticed was iatrogenic damage to dental roots.

Conclusion

Use of intraoral cortical bone screws for IMF is a valid alternative to arch bars in the treatment of mandibular fractures. Iatrogenic injury to dental roots is the commonest problem which can be minimized by an experienced surgeon.Key Words: Intermaxillary fixation, Bone screws, Mandibular fractures, Iatrogenic injury     

Evaluation of antihyperglycemic activity of methanolic Tecomaria capensis Thunb. (Bignoniaceae) leaves extract in alloxan induced hyperglycemic rats

ObjectiveTo evaluate the antihyperglycemic activity of Tecomaria capensis (T. capensis) Thunb. (Bignoniaceae) methanolic leaves extract (TCLE) using blood glucose level in normal fasted rats, glucose tolerance test and alloxan induced hyperglycemia models.MethodsTCLE (100, 300, 1 000 and 2 000 mg/kg body wt.) was given to rats orally to observe acute toxicity, and observed for 14 d. TCLE 200 and 400 mg/kg, and glibenclamide 0.6 mg/kg were given orally in all models.ResultsResults demonstrated that the no mortality was reported even after 14 d. This indicates that the methanol extract is safe up to a single dose of 2 000 mg/kg body weight. TCLE (200 and 400 mg/kg p.o.) exhibited remarkable blood glucose lowering effect in blood glucose level in normal fasted rats, glucose tolerance and alloxan induced hyperglycemia model. Cholesterol and triglyceride also decreased in alloxan induced hyperglycemia model.ConclusionsThe results of this study exhibites that methanol extract of T. capensis possesses antihypergycemic activity and it may prove to be effective for the treatment of hyperglycemia.
