The pattern of pulmonary blood flow was studied in three patients after a total cavopulmonary shunt procedure. Doppler studies showed a phasic pattern of flow which varied with the respiratory cycle. Pulmonary blood flow was increased with normal inspiration, and was much augmented by the Mueller manoeuvre. This suggests that flow was occurring when a negative intrathoracic pressure was generat...

We demonstrated a noninvasive management of early bleb leak following trabeculectomy using cyanoacrylate tissue glue (CATG). Three patients who underwent augmented trabeculectomy with mitomycin C with early bleb leak between January 2009 and June 2010 were reviewed. Case 1 and Case 2 exhibited bleb leak on postoperative Day 1 and Case 3 showed leak on follow-up at postoperative Day 7. Case 1 wa...

A validation study of the continuous noninvasive tonometric blood pressure monitor called JENTOW was performed in 20 normotensive subjects and 10 hypertensive patients. Tonometric and intra-arterial blood pressures were simultaneously recorded at supine rest and during a Valsalva maneuver and tilting test. The results of the strict evaluation of the instrument's capacity for reproducing intra-a...

Users of particulate air-purifying respirators are typically told to change their filters when breathing resistance becomes uncomfortable. It has been proposed that a noticeable increase in breathing resistance (pressure drop) may increase airflow through respirator faceseal leaks. This logic has been extended to suggest that respirator user exposure to contaminants may increase because of this...

We discuss the influence of increased pressure (compression and decompression in the hyperbaric chamber) on the human body, in particular the organ of vision. An extraordinary, quite rare case of painless loss of vision connected with retinal hemorrhage, followed by scarring in the person who performed the Valsalva maneuver working inside the hyperbaric chamber. The lesion was determined with h...

PURPOSE Despite reports of persistent stress urinary incontinence (SUI) in patients after the midurethral sling (MUS) procedure, there is no widely accepted definition or cause of the condition. In many cases, the mesh implanted in the previous MUS procedure has been found to have migrated proximally. The aim of this study was to evaluate the efficacy of the modified distal urethral polypropyle...

BACKGROUND The objective of this prospective observational study was to evaluate the association between the airflow and intrapleural pressures digitally recorded during the immediate postoperative period after lobectomy and their ability to predict the risk of subsequent prolonged air leak (PAL). METHODS A total of 145 consecutive patients underwent pulmonary lobectomy in two centers. All pa...

The relationship between recalled frequency of penile-vaginal intercourse (FSI) and resting heart rate variability (HRV; an index of parasympathetic tone), resting diastolic blood pressure (DBP) and heart rate (HR) response to the Valsalva maneuver was examined in 51 healthy adults aged 20-47 (subjects scoring above the 86th percentile on the Lie scale of the Eysenck Personality Inventory (EPI)...

UNLABELLED Bulbourethral transobturator sling data from other investigators report a success rate from 53% to 85%. Since the degree of sling tension and its adjustment seems to be important for achieving complete urinary continence we present results on the first consecutive 12 patients, with mild post prostatectomy stress urinary incontinence--defined as--less than 500 ml, who underwent a new ...

BACKGROUND Continuous positive airway pressure (CPAP) maintains a constant pressure to reduce the patient's work of breathing (WOB). The aim of this study was to measure the additional WOB imposed by four current CPAP devices during simulation of a difficult but commonly encountered clinical situation. METHOD Flow contour, respiratory system compliance and total lung-airway resistance of a pa...
