Most folks remember puberty – and not always in a good way. It can be an awkward stage of budding breasts, unwanted hair, acne and unexpected body odor. Puberty, when a child undergoes physical changes and becomes sexually mature, typically begins around age 8 in girls and age 9 in boys. But imagine, say, a 6- or 7-year-old undergoing such changes? Studies are showing that the onset of puberty for both boys and girls is occurring earlier and earlier, a phenomenon defined as precocious puberty. A study published in Pediatrics in 2010 found that among a population of 1,200 American girls, about 23 percent of African-Americans,15 percent of Latinas and 10 percent of Caucasian girls had begun puberty (marked by breast development) at age 7. In 2012, another study published in Pediatrics found that puberty in American boys – measured by testicular enlargement and pubic hair growth – was beginning six months to two years earlier than what research in previous decades had documented, particularly among African-American children.

-A finding of ASC on cytology requires further investigation to exclude precancerous lesions. Recommendations differ for women age 21 -24 and those age ;::25. For women age 21 -24 with ASCUS or low-grade squamous intraepitheliallesion (LSIL), current guidelines recommend repeating Pap smear in one year. In this younger patient population, HPV infection is transient and malignant transformation is rare. Therefore, colposcopy is not performed unless the patient demonstrates ASC-US or LSIL on 3
Wisdom teeth extractions can rear their ugly head later in life. This is a video of a patient with neck pain and neck weakness. When we stimulated the nerve fibers in the area of the extracted teeth there was an immediate improvement in her ability to control her neck muscles.
-The cremasteric reflex test is considered positive if there is elevation of the testis in response to stroking the upper inner thigh. This reaction is typically absent in testicular torsion and boys under the age of 6 months. Although not completely reliable in older boys and adults, an absent cremasteric reflex is highly suggestive of torsion. Patients with epididymitis usually have a normal cremasteric reflex, with pain and swelling isolated to
