Background. The inferior hypogastric plexus mediates pain sensation through the sympathetic chain for the lower abdominal and pelvic viscera and is thought to be a major structure involved in numerous pelvic and perineal pain syndromes and conditions. Objectives. The objective of this study was to demonstrate the structures affected by an inferior hypogastric plexus blockade utilizing the transsacral approach. Study Design. This is an observational study of fresh cadaver subjects. Setting. The cadaver injections and dissections were performed at the Department of Forensic Sciences and Insurance Medicine, Semmelweis University, Budapest, Hungary after obtaining institutional review board approval. Methods. 5 fresh cadavers underwent inferior hypogastric plexus blockade with radiographic contrast and methylene blue dye injection by the transsacral fluoroscopic technique described by Schultz followed by dissection of the pelvic and perineal structures to localize distribution of the indicator dye. Radiographs demonstrating correct needle localization by contrast spread in the specific tissue plane and photographs of the dye distribution after cadaver dissection were recorded for each subject. Results. In all cadavers the dye spread to the posterior surface of the rectum and the superior hypogastric plexus. The dye also demonstrated distribution to the anterior sacral nerve roots of S1, 2, and 3 with bilateral spread in 3 cadavers and ipsilateral spread in 2 of them. Limitations. The small number of cadaver specimens in this study limits the results and generalization of their clinical significance. Conclusions. Inferior hypogastric plexus blockade by a transsacral approach results in distribution of dye to the anterior sacral nerve roots and superior hypogastric plexus as demonstrated by dye spread in freshly dissected cadavers and not by local anesthetic spread to other pelvic and perineal viscera.

Background: Treatment of bulky retroperitoneal malignancy may require en bloc resection of the infrarenal inferior vena cava. A number of reconstructive options are available to the surgeon but objective haemodynamic assessment of the peripheral venous system following resection without replacement is lacking. The aim of the present paper was thus to determine the symptomatic and haemodynamic effects of not reconstructing the resected infrarenal inferior vena cava. Methods: A retrospective descriptive study was carried out at Princess Alexandra Hospital in Queensland. Five patients underwent resection of the thrombosed infrarenal inferior vena cava as part of retroperitoneal lymph node dissection for testicular cancer (n = 3), radical nephrectomy for renal cell carcinoma (n = 1) and thrombosed inferior vena cava aneurysm (n = 1). Clinical effects were determined via the modified venous clinical severity score and venous disability score. Haemodynamic data were obtained postoperatively using venous duplex ultrasound and air plethysmography. Results: None of the present patients scored >2 (out of 30) on the modified venous clinical severity score or >1 (out of 3) on the venous disability score. Haemodynamic studies showed only minor abnormalities. Conclusions: Not reconstructing the resected thrombosed infrarenal inferior vena cava results in minor signs and symptoms of peripheral venous hypertension and only minor abnormalities on haemodynamic assessment.

Objectives: To assess narrowing of the inferior dental canal in the lower third molar regions using computed tomography (CT) and to determine the value of radiographic markers on rotational panoramic radiographs in assessing the true relationships of the inferior dental canal. Methods: Patients referred for CT assessment of impacted lower third molars were used in this study. The lower third molars were assessed using CT to determine the position and morphology of the inferior dental canal relative to the roots and the cortical plates. The radiographic markers on rotational panoramic radiographs were correlated with the CT findings when rotational panoramic radiographs were available. Results: The patients referred had 202 lower third molars. Inferior positioning of the inferior dental canal was the most common location on CT. Narrowing of the inferior dental canal was found in relation to the lower third molars in 66.8% of cases. The chance of narrowing of the inferior dental canal as shown using CT increased when at least one of the radiographic markers, superimposition, narrowing, deviation or reduction in density was present on the rotational panoramic radiograph. Deviation of the inferior dental canal on rotational panoramic radiographs was found to be the most significant predictor of narrowing of the inferior dental canal and a close relationship to the roots, as shown in CT. Conclusions: Narrowing of the inferior dental canal is a common finding when impacted lower third molars are assessed using CT. On rotational panoramic radiographs deviation of the inferior dental canal is the best predictor of narrowing of the inferior dental canal and a close relationship to the roots.

Advocates of liberal democracy argue that its principles and practices contribute directly to peace (at both inter-state and domestic levels). They rely on ideals such as the rule of law, institutional checks and balances on power, an ethos of tolerance, and free market economics to deliver the liberal peace. Liberals, however, overlook three important features embedded in the construction of liberal democracy which can serve to facilitate political violence: 1) the fixed and thus non-negotiable nature of liberal democracy’s core principles, 2) the inferior manner in which it conceives ‘Other’ social orders that do not share its core principles, and 3) the urge to proselytise Others. Together, these constitutive qualities can facilitate moves by leaders of Other groups to argue that liberal democracy threatens ‘their’ preferred identity, and thus its promised peaceful outcomes can be put in doubt.
