Every day, specialists deliver high-quality care in 68 disciplines in health centres across Canada. Yet many Canadians know very little about what many specialists actually do, and the important role these disciplines play in Canada’s health care system.
A semen analysis, also called "seminogram" evaluates certain characteristics of a male's semen and the sperm contained therein. It is done to help evaluate male fertility, whether for those seeking pregnancy or verifying the success of vasectomy
An intracranial hematoma occurs when a blood vessel ruptures within your brain or between your skull and your brain. The collection of blood (hematoma) compresses your brain tissue. An intracranial hematoma may occur because the fluid that surrounds your brain can't absorb the force of a sudden blow or a quick stop. Then your brain may slide forcefully against the inner wall of your skull and become bruised. Although some head injuries — such as one that causes only a brief lapse of consciousness (concussion) — can be minor, an intracranial hematoma is potentially life-threatening and often requires immediate treatment. An intracranial hematoma often, but not always, requires surgery to remove the blood.
Lymphoma is cancer of the lymph system (or lymphatic system), which is part of our immunity. It is characterized by the formation of solid tumors in the immune system.1 The cancer affects immune cells called lymphocytes, which are white blood cells. Diagram of the lymphatic system The lymphatic system is a system of vessels that branch back from virtually all our tissues to drain excess fluids and present foreign material to the lymph nodes. Learn more about the lymphatic system here. Statistics from the US National Cancer Institute estimate that there are nearly 20 cases of non-Hodgkin's lymphoma for every 100,000 people in the American population.2 Hodgkin's lymphoma, meanwhile, is relatively rare, with around three cases in every 100,000 people.3
Meniscus allograft survival in patients with moderate to severe unicompartmental arthritis: a 2- to 7-year follow-up.PURPOSE: We present meniscus allograft survival data at least 2 years from surgery for 45 patients (47 allografts) with significant arthrosis to determine if the meniscus can survive ...in an arthritic joint. Type of Study: Prospective, longitudinal survival study. METHODS: Data were collected for 31 men and 14 women, mean age 48 years (range, 14 to 69 years), with preoperative evidence of significant arthrosis and an Outerbridge classification greater than II. Failure is established by previous studies as allograft removal. No patient was lost to follow-up. RESULTS: The success rate was 42 of 47 allografts (89.4%) with a mean failure time of 4.4 years as assessed by Kaplan-Meier survival analysis. Statistical power is greater than 0.9, with alpha = 0.05 and N = 47. There was significant mean improvement in preoperative versus postoperative self-reported measures of pain, activity, and functioning, with P = .001, P = .004, and P = .001, respectively, as assessed by a Wilcoxon rank-sum test with P = .05. CONCLUSIONS: Meniscus allografts can survive in a joint with arthrosis, challenging the contraindications of age and arthrosis severity. These results compare favorably with those in previous reports of meniscus allograft survival in patients without arthrosis. LEVEL OF EVIDENCE: Level IV.
Multiple Sclerosis Multiple sclerosis (MS) affects the brain and spinal cord. Early MS symptoms include weakness, tingling, numbness, and blurred vision. Other signs are muscle stiffness, thinking problems, and urinary problems. Treatment can relieve MS symptoms and delay disease progression.
