Retroperitoneal Hematoma as a Complication of Endovascular Embolization of Tumor Epistaxis: A Case Report.

Retroperitoneal hematomas are a rare and fatal complication of endovascular embolization. We report a case of an 89-year-old woman who was referred to interventional radiology for percutaneous embolization for intractable epistaxis as a result of a left nasal cavity mucosal melanoma. After successful embolization of the left sphenopalatine artery, the patient became hypotensive and was transferred to the intensive care unit.

Thyroglossal duct cyst anterior to the sternum: a novel presentation of a common lesion.

Thyroglossal duct cysts (TDCs) arise in roughly 7% of the general population and are typically diagnosed in childhood within the first decade of life. Typically, patients present with a painless, midline neck mass in close proximity to the hyoid bone which classically elevates with deglutition and tongue protrusion. We present a case of TDC found anterior to the sternum, a major deviation from the classical understanding of this lesion.

Comparison of steroid-releasing stents vs nonabsorbable packing as middle meatal spacers.

Background: A randomized controlled trial was held to compare nonabsorbable packs to steroid-eluting absorbable stents as middle meatal spacers after endoscopic sinus surgery in patients with chronic rhinosinusitis (CRS).

Methods: CRS patients were randomly assigned to receive either nonabsorbable Merocel packs wrapped in non-latex glove material (packing type A) or Propel steroid eluting stents (packing type B). Twenty-two-item Sino-Nasal Outcome Test (SNOT-22) scores were collected preoperatively and postoperatively during the initial 4 debridements up to 3 months.

Intraseptal Mucocele as a Long-term Complication of Revision Septorhinoplasty: A Case Report and Review of a Rare Entity.

Paranasal sinus mucoceles are benign, expansive, cystic lesions which arise from retention of mucus secretions. They arise primarily in the setting of cystic degeneration of the sinus mucosa or secondarily in the setting of obstruction of the sinus ostium due to mucosal trauma or chronic inflammation. Septal mucoceles are rare.

The use of multiphase nonlinear mixed models to define and quantify long-term changes in serum prostate-specific antigen: data from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial.

Purpose: To test the hypothesis that the pattern of prostate-specific antigen (PSA) change in men diagnosed with high-risk prostate cancer (PrCA) differs from the pattern evident in men diagnosed with low-risk PrCA or those with no evidence of PrCA.

Methods: A retrospective cohort study from which PSA measures were taken before PrCA diagnosis from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Data were fitted using a nonlinear regression model to estimate the adjusted absolute and relative (%) change of PSA.

Clinical and quality-of-life outcomes following gland-preserving surgery for chronic sialadenitis.

Objectives/hypothesis: Gland-preserving salivary surgery utilizing salivary endoscopy has been proposed as a treatment alternative in the management of chronic sialadenitis. This study seeks to determine medium-term clinical and quality-of-life (QOL) outcomes following a gland-preserving approach for chronic sialadenitis.

Study Design: Cross-sectional survey with retrospective chart review.

The importance of renal prostaglandin synthesis in maintaining renal blood flow and glomerular filtration after renal artery stenosis in the conscious dog.

We studied the effects of inhibiting prostaglandin synthesis on the renal blood flow and glomerular filtration rate of four conscious dogs with chronic unilateral renal artery stenosis. Dogs were prepared by exteriorizing the bladder trigone to allow repeated split renal function studies. Renal artery stenosis was produced with a Goldblatt clamp on one renal artery.

Sexual dysfunction in uremia.

A retrospective study of 50 chronic home hemodialysis patients and 20 transplant recipients revealed: 1) sexual dysfunction occurs with the development of renal insufficiency and does not appear to improve during chronic hemodialysis; 2) recovery may follow successful renal transplantation, but not always; 3) drug therapy appears beneficial in the treatment of uremic hypogonadism and sexual dysfunction; 4) professional couselling is of paramount importance and recommended during all phases of treatment.
