The inferior hypogastric plexus (IHP) lies in the extraperitoneal pelvis, and supplies branches to pelvic and perineal viscera. In men, the rectoprostatic fascia (Denonvillier's fascia) forms a distinct double fascial layer between the seminal glands and the rectum. The hypogastric nerve projections to the prostate and seminal glands run anterior to this.

This study investigates whether increasing perfusion pressure of radiographic contrast in cadaveric studies altered the radiographic appearance of vessels, particularly by distending their anastomotic connections.
Methods: From 10 fresh cadavers, bilateral upper limbs above the elbow were removed.

The quality of perinatal conditions directly influences the physical and immunological development of nestlings, yet it is inherently variable across space and time. Long-term breeding data for a population of Swainson's hawks () in northern California show a continuum of territory occupancy and productivity values of individual territories and nests. Here we explore effects of variation among territories on immune system development.

View Article and Find Full Text PDFBackground:: A well-fitting and comfortable ischial containment socket relies on accurately replicating the transverse plane angle of the ischium and ischial ramus angle, inside the medial socket brim. Prediction of the ischial ramus angle, may provide a way to determine the ischial ramus angle without in vivo measurement.
Objectives:: To determine the accuracy with which the ischial ramus angle could be predicted and identify which variables contributed significantly to the prediction.
Background: The lower limb is a source of many flaps both for closure of local defects and for free transfer. Fasciocutaneous flap techniques have been progressively refined, although the vascular basis for their success needs clarification.
Methods: Archival studies of 48 lower limbs were reviewed and combined with 20 studies of lower limbs from fresh cadavers, making a total of 68 investigations.
Clinical gait analysis incorporating three-dimensional motion analysis plays a key role in planning surgical treatments in people with gait disability. The position of the Hip Joint Centre (HJC) within the pelvis is thus critical to ensure accurate data interpretation. The position of the HJC is determined from regression equations based on anthropometric measurements derived from relatively small datasets.
View Article and Find Full Text PDFAccurate measurement of the pelvis is critical for well-fitting and comfortable ischial containment sockets. The "Skeletal Medial-Lateral (ML)" is intrusive and unreliable to measure in vivo. This study aimed to determine how accurately the Skeletal ML could be predicted and to identify which measurements were significant predictors.

It allows accurate, meaningful inter-provider comparison. It is therefore an essential component of any audit and quality improvement process.

The objective of this study was to assess the ease with which the sciatic nerve could be imaged in the midthigh region using ultrasound and to describe the anatomy surrounding the sciatic nerve at this location.
Methods: In this prospective observational study, 40 patients scheduled for surgery where sciatic nerve block was indicated were scanned between the gluteal and the popliteal regions using an ultrasound machine (Vivid-i, GE Healthcare, Chalfont St.
The frequency of mass disasters is increasing, demanding actions that deal with these promptly and effectively to secure human interests. An undeniable and inevitable reality of any mass disaster is the massive number of fatalities, which will give rise to a further chain of events ranging from the recovery of the deceased, to their transport, storage, identification and, finally, disposal. Past experience has shown that traditional human disposal methods should be redesigned according to the requisites of mass fatality scenarios, and it has been proven that a proper mass burial is by far the most appropriate and standard method for disposal of the dead due to mass disasters as it takes all its practical issues into consideration.

Objectives: The objective of the study is to clarify potential risks to the dorsal nerve of the clitoris (DNC) and obturator canal using different minimally invasive slings.
Study Design: Ten embalmed hemipelves were dissected to demonstrate the course of the DNC and the obturator canal. On each cadaver, tension-free vaginal tape (TVT), transobturator in-out (TVT-O) and transobturator out-in (Monarc) procedures were performed.
Management of perinatal torsion varies between centers from urgent surgical exploration and contralateral fixation to conservative nonoperative management. We present a case of paratesticular abscess in a neonate mimicking a perinatal torsion which may influence management of this condition in some cases.
