BACKGROUND Patients are referred to ophthalmologists to evaluate for papilledema when they are found to have elevated cerebrospinal fluid (CSF) pressure. However, some of these patients have no clinical history consistent with intracranial hyper-tension. We aimed to determine how often and how high patients with normal opening pressure could artificially elevate their CSF pressure to a pseudo-p...

PURPOSE We examined the effect of the Monarc suburethral sling on urethral mobility. MATERIALS AND METHODS We retrospectively studied the records of 54 consecutive women who received a Monarc suburethral sling between July 2005 and November 2008. All patients were examined by volume ultrasound preoperatively and at followup (average 0.7 years). Volume data sets were analyzed using post-proces...

To the Editor: The echocardiogram on the cover of the June 1, 1999, issue of Circulation is a beautiful illustration of an impending paradoxical embolism. Unfortunately, neither the text1 nor the key words of the article made any mention of this condition. Impending paradoxical embolism2 is a surgical emergency. This diagnosis would not have been possible before the advent of echocardiography. ...

Previous models combining the human cardiovascular and pulmonary systems have not addressed their strong dynamic interaction. They are primarily cardiovascular or pulmonary in their orientation and do not permit a full exploration of how the combined cardiopulmonary system responds to large amplitude forcing (e.g., by the Valsalva maneuver). To address this issue, we developed a new model that ...

A patient who had had trauma to the right shoulder and upper chest complained of a right supraclavicular mass. Examination revealed a cystic tumor made larger by performance of the Valsalva maneuver. Angiocardiography demonstrated that there was partial stenosis of the terminal end of the right innominate vein. This and the Valsalva manenvnr were responsible for the filling of a right persisten...

OBJECTIVE To determine the effect of pregnancy and vaginal delivery on the pelvic floor and levatorani morphology and function. METHODS Design. Cross-sectional study. Setting. Tertiary care teaching hospital. Population. 75 primigravid women were recruited for assessment at 6 weeks postpartum compared with 25 nulliparous women. Hiatal morphology and levator ani muscle avulsion were assessed b...

The second heart sounds in 29 cases with right bundle branch block, mainly surgically induced, were studied. Three general types of the second sound were classified. Eleven cases revealed wide splitting of the second sound (0.05 sec. or more), and 14 cases showed narrow splitting less than 0.05 sec.), while 4 cases showed a single 2nd heart sound throughout the respiratory cycle. Ten cases reve...

Introduction The use of vagal nerve stimulation is identified as a proper treatment option in patients with stable supraventricular tachycardia (SVT). This study aimed to assess the success of Valsalva maneuver via a handmade device in reversion of SVT. Methods In this quasi experimental study, using a handmade device, vagus nerve stimulation was performed for SVT patients presenting to emerg...

Background: Autonomic neuropathy and vital organ dysfunctions are the known complications in type 2 diabetes Mellitus (DM). Genetic endowments involving individuals make subtle differences in physiological systems, particularly at the time of sickness. Hence, the presented study was designed to evaluate the vasomotor system in healthy people and type 2 DM cases for determining any functionality...

This study evaluated the efficacy of the valsalva maneuver that can induce baroreceptor activation and nociception, on needle projection pain and hemodynamic responses associated with spinal puncture. Ninety adults, ASA physical status I and II undergoing elective surgeries were included. Patients were randomized into three equal groups. Group I (C): control; Group II (B): ball; pressed a rubbe...
