RESUMEN
A 29-year-old female had presented to surgical outpatient's department complaining of lump in the anterior abdominal wall. Ultrasound and magnetic resonance imaging revealed a solid degenerated tumor in the anterior abdominal wall. It was surgically excised, and histopathology confirmed it to be "ancient" schwannoma. To our knowledge, this is the second reported case of an abdominal wall ancient schwannoma in the medical literature.
RESUMEN
This study discusses the definition of operative, anatomic and radiographic acetabular anteversion and their effect on a long posterior wall cup. In this cadaveric study, anteversion was modelled radiographically with a Charnley double wire marker Long Posterior Wall (LPW) cup and the position of the long posterior wall was studied with relation to different anteversion angles, and also correlated with computer generated line diagrams of the acetabular cup. The position of a long posterior wall varies when different types of anteversion are applied. By increasing the operative anteversion the long posterior wall comes to lie inferiorly and the advantage of the long posterior wall is lost. In light of prior confusion with definitions and in an attempt to make the terms more relevant to the surgical technique we propose the simplified alternate terms of 'flexion-anteversion' previously called 'operative anteversion', 'internal rotation-anteversion' previously called 'anatomic anteversion' and 'combined anteversion' previously called 'radiographic anteversion'. If the surgeon elects to use LPW it is important to understand the effect of each type of anteversion on eventual position of the raised wall.

The effect of salbutamol, a selective beta 2-adrenergic agonist versus ipratropium bromide anticholinergic agent on creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) activity in serum of 20 asthmatic patients was investigated. Twenty asthmatic subjects (12 males and 8 females) were studied. They were aged 45 +/- 5 years and had moderate airway obstruction FEV1 was 65 +/- 7 and FEV1% VC 64 +/- 6 of predicted value. Venous blood was obtained before and 30 min and 2 h after two puffs of salbutamol (200 micrograms) or ipratropium bromide (80 micrograms). Total creatinine activity was assayed on a Technico RA-1000 analyzer with the IFCC recommended method. CK-MB activity was determined using a centrifugal analyzer (Cobas Fera, Roche Switzerland). Reagent kits were provided by Boehringer Mannheim Germany. We observed statistically significant increase of CK-activity in three subjects and found increase of CK-MB activity in five patients after salbutamol inhalation. Mean serum CK-MB activity before treatment was 13.0 +/- 8 UI/l, 14 +/- 5 IU/l after 30 min of drug inhalation and after 2 h 19 +/- 6 IU/l, but it was not significant. We did not found any changes after ipratropium bromide. We conclude that salbutamol exerts an influence on cardiac muscle and it is probably connected with adrenergic stimulation.
