This study compares the coordination patterns employed for the left and right arms during rapid targeted reaching movements. Six right-handed subjects reached to each of three targets, designed to elicit progressively greater amplitude interaction torques at the elbow joint. All targets required the same elbow excursion (20 degrees ), but different shoulder excursions (5, 10, and 15 degrees, re...

OBJECTIVE To compare the effect of induction position on block characteristics (sensory and motor nerves) and haemodynamic stability in elderly patients with isobaric bupivacaine. Patient comfort was also looked at. METHODS The randomized single blinded study was conducted at the Aga Khan University Hospital, Karachi, from September 2007 to August 2008. A total of 70 patients aged >60 years o...

a doublet of earthquakes with magnitudes of 6.5 and 6.2 in mw scale (global cmt) on 2010 december 20 and 2011 january 27 respectively struck the area that lies between the nehbandan and jiroft fault systems, southeast of iran. these earthquakes occurred in correspondence of the southwestern termination of the kahourak right lateral strike slip fault. the focal mechanisms of both the mainshocks ...

the purpose of this report is to present a rare case of a fused mandibular lateral incisor with supernumerary tooth with a follow-up for 18-months. a 35-year-old female patient was referred to our clinic with an extraoral sinus tract in the chin. the intraoral diagnosis revealed the fusion of her mandibular lateral incisors. vitality pulp tests were negative for mandibular right central and lat...

OBJECTIVE To evaluate new echocardiographic modes in the diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC). DESIGN Prospective observational study. SETTING University Hospital. SUBJECTS 15 patients with ARVC and a control group of 25 healthy subjects. METHODS Transthoracic echocardiography included cross sectional measurements of the right ventricular outflow tract, ri...

Resection and simultaneous reconstruction with free flaps of wide tumours of the scalp and posterior neck region are difficult to perform through a single surgical approach. In such cases, the park-bench position - a lateral oblique position - could allow simultaneous resection and reconstruction of tumours of the scalp and occipital region without changing the patient's position. In the case d...

OBJECTIVES/HYPOTHESIS Currently, drug-induced sleep endoscopy (DISE) in obstructive sleep apnea (OSA) is predominantly performed in supine position. When positional therapy (avoidance of supine sleeping position in positional OSA (POSA) is implemented as (part of the) treatment, one should assess levels of obstruction in the other sleeping positions. Therefore, the current study examined the in...

Abstract Background Intracorporeal suturing is an essential component of any advanced laparoscopic procedure like fundoplication, bypass surgery or common bile duct exploration. Obtaining the appropriate needle mount during can be challenging. Spatial geometry defines points in three-dimensional space. Ergonomics identifies a manipulation angle 60o to target as being optimal. This knowledge, co...

INTRODUCTION This quality improvement study tested three methods of tattoo alignment and isocentre definition to investigate if aligning lateral tattoos to minimise pitch, roll and yaw decreased set-up error, and if defining the isocentre using the lateral tattoos for cranio-caudal (CC) position improved isocentre reproducibility. The study population was patients receiving curative external be...
