Erectile function outcomes following surgical treatment of ischemic priapism.

Introduction: Ischemic Priapism is defined as an abnormally prolonged state of erection, exceeding 6 h, often and irreducible, occurring without any sexual stimulation. Ischemic priapism has a fatal consequence on the sexual function of men if it's not promptly managed. This pathology can cause erectile dysfunction and this can alter the quality of life of patients.

Double retroperitoneal hydatid localization: About a case report.

The hydatid cyst is a parasitic pathology which is endemic in Tunisia and presents a public health problem.Hydatid cysts located in the retroperitoneum, especially around or in the kidney, are rare and only represent 5% of visceral locations. The kidney is the most commonly affected organ of the urinary tract.

The Broad Application of Prepectoral Direct-to-Implant Breast Reconstruction with Acellular Dermal Matrix Drape and Fluorescent Imaging in a Community Setting.

Background: Much has been written regarding the new paradigm of prepectoral direct-to-implant reconstruction, but patient selection continues to be unclear. Prepectoral direct-to-implant (PDTI) reconstruction with acellular dermal matrix drape and fluorescent imaging (ADFI) was offered to all patients.

Methods: The PDTI with ADFI protocol is (1) fluorescent imaging following mastectomy, (2) acellular dermal matrix prepectoral drape construction, (3) direct-to-implant placement beneath drape, and (4) repeated fluorescent imaging with implant in place.

In vivo estimates of NO and CO conductance for haemoglobin and for lung transfer in humans.

Membrane conductance (Dm) and capillary lung volume (Vc) derived from NO and CO lung transfer measurements in humans depend on the blood conductance (θ) values of both gases. Many θ values have been proposed in the literature. In the present study, measurements of CO and NO transfer while breathing 15% or 21% O2 allowed the estimation of θNO and the calculation of the optimal equation relating 1/θCO to pulmonary capillary oxygen pressure (PcapO2).

Partial versus maximal forced exhalations in COPD: enhanced signal detection for novel therapies.

Background: Evaluation of novel compounds for COPD often relies on FEV1 for signal detection. Partial forced exhalations from end-tidal inspiration (PEFV) might complement FEV1 in identifying such a signal. We examined the prevalence of bronchodilator response (BDR) using PEFV and FEV1 in patients with COPD.

Office cystoscopy and transrectal ultrasound-guided prostate biopsies pose minimal risk: prospective evaluation of 921 procedures.

Objectives: To examine the outcomes of 2 commonly performed urologic office procedures as a part of a process to align these with the Joint Commission standards to ensure patient safety. We determined whether cystoscopy and transrectal ultrasound-guided prostate biopsy performed in the office setting pose minimal risk to patients.

Methods: An evaluation of urologic office procedures in the office clinic setting of an academic medical center was prospectively performed during 3 different periods to document patient and system events.

Specificity of amino acid regulated gene expression: analysis of genes subjected to either complete or single amino acid deprivation.

Amino acid deprivation activates the amino acid response (AAR) pathway that enhances transcription of genes containing an amino acid response element (AARE). The present data reveal a quantitative difference in the response to deprivation of individual amino acids. The AAR leads to increased eukaryotic initiation factor 2alpha (eIF2alpha) phosphorylation and ATF4 translation.

Effect of changing the gravity vector on respiratory output and control.

We studied the respiratory output in five subjects exposed to parabolic flights [gravity vector 1, 1.8 and 0 gravity vector in the craniocaudal direction (Gz)] and when switching from sitting to supine (legs bent at the knees). Despite differences in total respiratory compliance (highest at 0 Gz and in supine and minimum at 1.

Effect of gravity and posture on lung mechanics.

The volume-pressure relationship of the lung was studied in six subjects on changing the gravity vector during parabolic flights and body posture. Lung recoil pressure decreased by approximately 2.7 cmH(2)O going from 1 to 0 vertical acceleration (G(z)), whereas it increased by approximately 3.

Objective: This work was carried out to study induction with sevoflurane in adult patients with predictive signs of difficult intubation.

Study Design: Randomised prospective study.

Patients And Methods: The study had two parts.

Effect of gravity on chest wall mechanics.

Chest wall mechanics was studied in four subjects on changing gravity in the craniocaudal direction (G(z)) during parabolic flights. The thorax appears very compliant at 0 G(z): its recoil changes only from -2 to 2 cmH(2)O in the volume range of 30-70% vital capacity (VC). Increasing G(z) from 0 to 1 and 1.

Changes in lower limb volume in humans during parabolic flight.

Variations in gravity [head-to-foot acceleration (Gz)] induce hemodynamic alterations as a consequence of changes in hydrostatic pressure gradients. To estimate the contribution of the lower limbs to blood pooling or shifting during the different gravity phases of a parabolic flight, we measured instantaneous thigh and calf girths by using strain-gauge plethysmography in five healthy volunteers. From these circumferential measurements, segmental leg volumes were calculated at 1, 1.

Pulmonary diffusing capacity and pulmonary capillary blood volume during parabolic flights.

Data from the Spacelab Life Sciences-1 (SLS-1) mission have shown sustained but moderate increase in pulmonary diffusing capacity (DL). Because of the occupational constraints of the mission, data were only obtained after 24 h of exposure to microgravity. Parabolic flights are often used to study some effects of microgravity, and we measured changes in DL occurring at the very onset of weightlessness.

Is proximal airway pressure a good reflection of peripheral airspace pressure in infants and children models under HFJV?

This experimental study was carried out to determine if an alveolar positive end-expiratory pressure (PEEP) could occur during high frequency jet ventilation (HFJV) in infants, and if tracheal pressure is a good estimation of alveolar pressure. We used physical models simulating a 1.5 kg premature (P), a 3 kg newborn (N) and a 6 kg child (C) with normal compliance and normal resistance.

Respiratory muscle function in trained and untrained adolescents during short-term high intensity exercise.

The breathing pattern and respiratory muscle function were investigated in ten trained and ten untrained adolescents (aged 15-16 years) while undergoing an incremental intensity exercise test on a cycle ergometer up to 80% maximal oxygen consumption (VO2max), maintained to exhaustion. Before and after exercise, maximal inspiratory (PImax) and expiratory (PEmax) pressures were measured at residual volume and total lung capacity, respectively. During exercise, the breathing pattern [tidal volume (VT), respiratory frequency (fR), ventilation] and the relative contribution of ribcage and abdomen to VT were assessed using inductance plethysmography.

EMG study of respiratory muscles in humans immersed at different water temperatures.

The electromyograms of the rectus abdominis (EMGra) and of the diaphragm (EMGdi) have been recorded on human subjects immersed at two bath temperatures (TW), 25 and 40 degrees C. The recordings were obtained during a calibrated isometric contraction sustained for 20 s against a closed stopcock at functional residual capacity (FRC) level for EMGra (expiratory effort) and at pulmonary volume greater than 90% vital capacity for EMGdi and EMGra (inspiratory effort). After eliminating the electrocardiographic artifact, the EMG signal was processed to obtain its root-mean-square (rms) value and three parameters of its frequency spectrum, total energy (Etot), centroid frequency (fc), and high-to-low ratio (H/L).

Effects of water temperature on pulmonary volumes in immersed human subjects.

Pulmonary volumes and capacities have been measured at three water temperatures (Tw = 25, 34, 40 degrees C) in standing subjects immersed up to the shoulders. The comparison of data obtained in air with those obtained in thermoneutral immersion (Tw = 34 degrees C) confirms the results previously published in several studies. The comparison of data obtained in immersion at different Tw shows: 1.
