This study examined effects of hand movement on visual perception of 3-D movement. I used an apparatus in which a cursor position in a simulated 3-D space and the position of a stylus on a haptic device could coincide using a mirror. In three experiments, participants touched the center of a rectangle in the visual display with the stylus of the force-feedback device. Then the rectangle's surfa...

OBJECTIVE To estimate the effects of a relatively protruded head and neck posture on postural balance, in computer based worker. METHOD Thirty participants, who work with computers for over 6 hrs per day (Group I), and thirty participants, who rarely work with computers (Group II), were enrolled. The head and neck posture was measured by estimating angles A and B. A being the angle between th...

IMPORTANCE Correction of the protruded lobule in otoplasty continues to represent an important challenge. The lack of skeletal elements within the lobule makes a controlled lobule repositioning less predictable. OBJECTIVE To present a new surgical technique for lobule correction in otoplasty. DESIGN, SETTING, AND PARTICIPANTS Human cadaver studies were performed for detailed anatomical analys...

BACKGROUND Infundibular dilatation (ID) is a funnel-shaped enlargement of the origin of cerebral arteries. The coexistence of an aneurysm and ID is relatively rare. Patients with IDs are rarely followed up. However, some IDs have been reported to develop into aneurysms with subsequent rupture. Here we report on a case of an aneurysm that coexisted with ID of the posterior communicating artery. ...

Myxobolus dogieli Bykhovskaya-Pavlovskaya & Bykhovski, 1940 is regarded as a site specific myxosporean, infecting the heart of cyprinid fish. During a survey of the myxosporean fauna of Lake Balaton fish, heart myxobolosis was found in the common bream, Abramis brama, with heavy infection of the ventricle and the bulbus arteriosus in some infected bream. Developing and mature plasmodia were mos...

BACKGROUND Pierre Robin sequence (PRS) refers to the association of micrognathia, glossoptosis, and airway obstruction. Cases with severe dyspnea due to upper airway obstruction immediately after birth are very rare. We here report two cases with PRS who developed severe dyspnea due to morphological abnormality immediately after birth and were rescued by fiberoptic nasotracheal intubation. CA...

At present low backache, pain in the distribution of the lower lumbar or first sacral roots, or the combination of these symptoms, are so often found to be due to protrusion of an intervertebral disc that other and less frequent causes may be forgotten. The protruded disc often causes symptoms in the form of recurrent lumbago over a period of many years before symptoms of root compression appea...

INTRODUCTION Our objective was to determine the short-term skeletal and dental effects of the Xbow appliance when compared with an equivalent untreated control group as measured on lateral cephalograms. METHODS A prospective sample of 69 consecutive Class II patients treated with only the Xbow appliance was compared with 30 historical Class II untreated controls. Standardized lateral cephalog...

background: inversion of the uterus is very uncommon. patients may present with pelvic pain, vaginal discharge, or hemodynamic shock. case: we report a case of 35 years old women (virgin) who was admitted with profuse vaginal bleeding and cramps of uterus. in the vaginal examination at litothomy position a mass of 58 cm in size was protruded from the vagina. at first myomectomy was performed a...

Narrow-band imaging (NBI) of surface microvessels of colorectal lesions is useful for differentiating neoplasms from non-neoplasms and for predicting histopathological diagnosis. Furthermore, NBI of surface microstructure, or 'surface pattern', is valuable for predicting histopathology in colorectal cancer. The aim of the present study was to investigate whether surface patterns could be used t...
