The July 2006 issue, which featured an update on STDs, included a case on primary syphilis in a teenager (page 427). Therapy with intramuscular penicillin G (weekly for 3 weeks) or ceftriaxone (daily for 2 weeks) was recommended. However, the CDC's newly published guidelines on STD treatment recommend therapy with a single intramuscular dose of 2.4 million units of penicillin G.1 If the patient is allergic to penicillin, the alternative is therapy with doxycycline (100 mg orally bid for 14 days) or tetracycline (500 mg qid for 14 days). Ceftriaxone is not a recommended treatment for syphilis.

Musculoskeletal infections in children include osteomyelitis, septic arthritis, and pyomyositis. Most of these infections are bacterial. Staphylococcus aureus is the most common organism in children in all age cat-egories. Others include group A Streptococcus, Neisseria meningitidis in purpura fulminans, Streptococcus pneumoniae, Neisseria gonorrhoeae, Mycobacterium tuberculosis, and Borrelia burgdorferi.

A 3-year-old boy with high fever, malaise, anorexia, and drooling of 3 days' duration was brought to the emergency department (ED). A bacterial throat infection was diagnosed, and oral antibiotic therapy was started.

With children two to three times more likely than adults to become ill with the flu and spread the virus to others, the National Association of School Nurses (NASN) has launched a program to educate parents and students about influenza. "Don't Get Sidelined by the Flu," includes educational materials-in English and Spanish-for school nurses to share with parents and students to raise awareness about flu prevention, recognition of symptoms, and treatment options.

Nationally, immunization levels are higher than ever, but new challenges mean no rest for the pediatric community. Consider these tips on maintaining immunization coverage-to help you preserve and extend essential protection for children in your care.

Musculoskeletal infections in children encompass a broad spectrum of entities that vary greatly in severity and complexity. Their presentation ranges from obvious and acute to insidious and chronic.

A 12-year-old boy from Pakistan presented with weakness, night sweats, anorexia, and chronic cough of 2 months' duration. He had undergone spinal surgery about 5 months before immigrating to the United States when acute paralysis, kyphosis, and a prominent midline hump (gibbus deformity) developed in his thoracic spine. The child appeared pale and weak but in no acute respiratory distress. His weight was 20.5 kg (45 lb). He had difficulty in walking without assistance. Muscle wasting was noted in the arms and legs, and he had a healing lesion on the left elbow that drained pus. Other physical examination findings were unremarkable except for a fever (temperature of 37.2°C [99°F]) and the gibbus deformity.

The Centers for Disease Control and Prevention (CDC) Advisory Committee on Immunization Practices (ACIP) unanimously voted on June 29 that children 4 to 6 years old receive a second dose of varicella vaccine for the prevention of chickenpox.

Child Protective Services (CPS) has asked you to evaluate a 6-month-old girl with a genital mass. The goal is to determine whether the "weird lump in the baby's private area"--noted while the child's diapers were being changed in day care--was the result of sexual abuse.

Fourteen-year-old JT is worried. During health class last week, he learned about the different sexually transmitted infections as well as about testicular self-examination. While practicing his monthly testicular examination in the shower, he noticed that he had a number of small growths on his penis. On further questioning, JT insists that he has never been sexually active with another person.

Your doctor has just told you that you have an infection with human papillomavirus (HPV). Most teens have a lot of questions about warts and HPV. This guide will help answer some of those questions.

Adolescents are at high risk for HPV infection because they tend to become involved with multiple simultaneous sexual partners rather than forming monogamous relationships.

Seven-year-old boy with red, nonpruritic rash that appeared first on the cheeks and then spread to the trunk, extremities, and buttocks. No history of respiratory, GI, or other symptoms in the several weeks before the onset of the rash. Patient is otherwise healthy.

A 10-year-old boy with no medical history was brought to his pediatrician's office with a 2-day history of intermittent fever (temperature of 38.8°C to 39.4°C [102°F to 103°F]). Physical examination results were unremarkable. There was no history of recent trauma. The child was sent home with analgesic therapy.

A 9-year-old girl was hospitalized because of a painful, vesicular rash on her genitals, groin, and buttocks. There was also concern about possible genital herpes infection in a minor.

This 13-year-old boy plays basketball for his school team. His mother brings him to your office and asks you about her son's toenail that has changed appearance and now looks like his father's great toenail. The father has psoriasis.

Most cases of HSV-2 infection are spread through sexual transmission. An infected person can have virus in his or her saliva, semen, or vaginal secretions. When a seronegative partner comes in sexual contact with these secretions, the virus can enter the body through mucosal surfaces (such as the vagina, anus, or mouth) or micro-abrasions on the skin (eg, the penile shaft, scrotum, thighs, or perineum).

This 7-year-old boy was recently brought to my office having received a diagnosis of pemphigus foliaceus. His parents were seeking a second opinion.

How did I get herpes? Is there a cure? What causes an outbreak-- and what can I do to prevent another one? My friend got herpes and had to stay in the hospital; will that happen to me? Can I still have children?

Until very recently, when it came to chronic cough, children were to be treated like little adults. In its 1998 guidelines on cough, the American College of Chest Physicians (ACCP) stated that "the approach to managing chronic cough in children is similar to the approach in adults."

Poisons have been a threat to the health and well-being of humankind for millennia. Given the ubiquitous nature of potential poisons, exposure to a toxin should be included in the differential diagnosis of patients with unexplained illnesses or unusual presentations.

Gonorrhea (aka "the clap," or "the drip") is caused by sexually transmitted Neisseria gonorrhoeae--a Gram-negative diplococcus. One of the most common reportable diseases in the United States, gonorrhea frequently affects sexually active adolescents. Approximately 30% of the 350,000 annual cases involve 15- to 19-year-olds. (That percentage is thought to be an underestimate!) Those most often infected are young women 15 to 24 years old. Recent data suggest that infection rates are higher among teens who are homeless or pregnant, and in those from a minority group or an economically disadvantaged background.

Seven-year-old girl with generalized rash that started as a single isolated oval lesion on the lower abdomen. Six days later, diffuse papulosquamous lesions appeared mainly on the trunk, sparing the scalp, face, and extremities. Intense itching despite 3 days of diphenhydramine therapy.

According to a study by investigators at the University of California, San Francisco School of Dentistry, fluoride varnish reduces the incidence of early childhood tooth decay in combination with dental health counseling for parents.
