Malignant spinal neoplasms: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Primary tumors of the spinal cord may be extramedullary (occurring outside the spinal cord) or intramedullary (occurring within the cord itself). Extramedullary tumors may be intradural (meningiomas and schwannomas), which account for 60% of all primary malignant spinal cord neoplasms, or extradural (metastatic tumors from breasts, lungs, prostate, leukemia, or lymphomas), which account for 25% of these malignant neoplasms.

Intramedullary tumors, or gliomas (astrocytomas or ependymomas), are comparatively rare, accounting for only about 10%. In children, they're low-grade astrocytomas.

Spinal cord tumors are rare compared with intracranial tumors (ratio of 1:4). They occur equally in men and women, with the exception of meningiomas, which occur mostly in women. Spinal cord tumors can occur anywhere along the length of the cord or its roots.

Throat abscesses: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Peritonsillar abscess is a complication of acute tonsillitis, usually after streptococcal or staphylococcal infection. It occurs more commonly in adolescents and young adults than in children.

Acute retropharyngeal abscess results from infection in the retropharyngeal lymph glands, which may follow an upper respiratory tract bacterial infection. Most common pathogens are beta-hemolytic Streptococcus and Staphylococcus aureus. These lymph glands begin to atrophy after age 2. Acute retropharyngeal abscess most commonly affects infants and children younger than age 2.

Chronic retropharyngeal abscess may result from tuberculosis of the cervical spine (Pott’s disease) and may occur at any age.

Incidence statistics for Throat cancer:

The following statistics relate to the incidence of Throat cancer:

• 27 new female cases of tracheal, bronchial and lung cancer per 100,000 population in Australia 2000 (Australia’s Health 2004, AIHW)
• 62 new male cases of tracheal, bronchial and lung cancer per 100,000 population in Australia 2000 (Australia’s Health 2004, AIHW)

About prevalence and incidence statistics:

The term 'prevalence' of Throat cancer usually refers to the estimated population of people who are managing Throat cancer at any given time. The term 'incidence' of Throat cancer refers to the annual diagnosis rate, or the number of new cases of Throat cancer diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
