Computerized Tomography Findings In Pediatric Renal Trauma - Indications For Early Intervention?
UroToday.com - The study out of Children's Hospital of Pittsburgh evaluated CT scans for blunt renal trauma to see if they correlated with the need for operative intervention when urinary extravasation was present.

A total of 17 patients with grade IV blunt renal trauma and urinary extravasation were identified between 2000 and 2007. Each CT scan was reviewed to determine location, size and number of sites of extravasation, as well as the presence of contrast material in the ipsilateral ureter. These were then compared to the findings at the time of surgery - whether surgey included stent placement, percutaneous urinoma drainage, angiographic embolization and nephrectomy.

Increased Risk Of Kidney Stone Disease Due To Global Warming, Predicts UT Southwestern Researchers
Global warming is likely to increase the proportion of the population affected by kidney stones by expanding the higher-risk region known as the "kidney-stone belt" into neighboring states, researchers at UT Southwestern Medical Center and UT Dallas have found.

Dehydration is one of the risk factors linked to kidney-stone disease, and the paper suggests global warming will exacerbate this effect. The researchers predict that by 2050, higher temperatures will cause an additional 1.6 million to 2.2 million kidney-stone cases, representing up to a 30 percent growth in some areas.

Information
Prostate cancer is the second leading cause of death among men. In 2002 it is estimated that 30,200 men will die from prostate cancer and 189,000 men will be diagnosed (American Cancer Society Facts & Figures 2002). The incidence of prostate cancer increases with age with 75% of all prostate cancers being diagnosed in men over the age of 65.

Prostate Cancer Management
The critical focus for the treatment of prostate cancer is to treat those cancers where it is necessary, and not to treat those that do not need it.

Decisions about the best management of prostate cancer can be complex and depend upon the:

Pathology of the cancer (unlike other cancers, prostate cancer often progresses very slowly)
Stage of the disease (non-metastatic (localized or locally advanced), metastatic or hormone refractory)
Age and general health of the patients at diagnosis
The impact that treatment can have on quality of life, including sexual activity.
Patient's preference for treatment
PSA at diagnosis

August is National Immunization Awareness Month
Vaccine-preventable disease levels are at or near record lows. However, we cannot take high immunization coverage levels for granted. To continue to protect America's children and adults, we must obtain maximum immunization coverage in all populations, establish effective partnerships, conduct reliable scientific research, implement immunization systems, and ensure vaccine safety.

Peyronie's Disease

Overview

Peyronie’s disease is characterized by the formation of hardened tissue (fibrosis) in the penis that causes pain, curvature, and distortion, usually during erection. The penis (male organ for reproduction and urination) is composed of two columns of erectile tissue (corpora cavernosa); the corpus spongiosum, which contains the urethra (tube that carries urine and semen from the body); and the tunica albuginea (sheath that surrounds the erectile tissue). In Peyronie’s disease, dense, fibrous scar tissue (plaque) forms in the tunica albuginea.

Incidence and Prevalence
According to a report published in 1995 by the National Institutes of Health, Peyronie’s disease occurs in about 1% of men. It is most common between the ages of 45 and 60, but it also occurs in young and elderly men. Prevalence may be higher because of reluctance to seek medical attention for the condition and failure to report in cases with mild symptoms.

Causes and Risk Factors

The cause of Peyronie’s disease is unknown. Cases that develop suddenly are often caused by trauma to the penis (e.g., invasive penile procedure, injury, extremely vigorous sexual activity). Invasive penile procedures include urethral catheterization, cystoscopy, and transurethral prostatectomy.

Cases of Peyronie’s that develop over time may be caused by an inherited abnormality of human leukocyte antigen B7 (HLA-B7), suggesting a genetic link. Also, Peyronie’s occurs more frequently in men with family members who have the condition or a connective tissue disorder (e.g., systemic lupus erythematosus). About 30% of patients with Peyronie’s disease also develop hardened tissue in other parts of the body, such as the hand (e.g., Dupuytren’s contracture) or the foot.

Microscopic examination of hardened tissue in cases of Peyronie’s disease is consistent with cases of severe vasculitis (inflammation of blood vessels), suggesting the condition may have a vascular (i.e., pertaining to blood vessels) cause. Diabetes, which often leads to blood vessel disease, is also considered a risk factor.

The use of the antihypertension medication propranolol (Inderal®) has been found to cause the condition in rare cases. Peyronie’s disease has also been associated with vitamin E deficiency.

Signs and Symptoms

Peyronie’s disease may be mild or severe, and may develop rapidly or over time. Symptoms include the following:

Hardened tissue (plaque) in the penis
Pain during erection
Curve in the penis during erection
Distortion of the penis (indentation, shortening)

Plaque usually develops on the top of the shaft, causing the penis to bend upward during erection, but it may occur on the bottom, causing a downward bend. If plaque develops on the top and the bottom, indentations and shortening may occur. In about 13% of cases, plaque does not cause severe pain or curvature, and the condition resolves on its own.

In severe cases, pain and curvature result in erectile dysfunction (impotence). If there are several areas of plaque, incomplete erection may occur.
