Common Acute Hand Infections - Article
ABSTRACT: Hand infections can result in significant morbidity if not appropriately diagnosed and treated. Host factors, location, and circumstances of the infection are important guides to initial treatment strategies. Many hand infections improve with early splinting, elevation, appropriate antibiotics and, if an abscess is present, incision and drainage. Tetanus prophylaxis is indicated in patients who have at-risk infections. Paronychia, an infection of the epidermis bordering the nail, commonly is precipitated by localized trauma. Treatment consists of incision and drainage, warm-water soaks and, sometimes, oral antibiotics. A felon is an abscess of the distal pulp of the fingertip. An early felon may be amenable to elevation, oral antibiotics, and warm water or saline soaks. A more advanced felon requires incision and drainage. Herpetic whitlow is a painful infection caused by the herpes simplex virus. Early treatment with oral antiviral agents may hasten healing. Pyogenic flexor tenosynovitis and clenched-fist injuries are more serious infections that often require surgical intervention. Pyogenic flexor tenosynovitis is an acute synovial space infection involving a flexor tendon sheath. Treatment consists of parenteral antibiotics and sheath irrigation. A clenched-fist injury usually is the result of an altercation and often involves injury to the extensor tendon, joint capsule, and bone. Wound exploration, copious irrigation, and appropriate antibiotics can prevent undesired outcomes.

ABSTRACT: The diagnosis and treatment of syphilis can present difficult dilemmas. Serologic tests can be negative if they are performed at the stage when lesions are present, and the VDRL test can be negative in patients with late syphilis. Cerebrospinal fluid examination is not required in patients with primary or secondary disease and no neurologic signs or symptoms, but it may be warranted in patients with late latent syphilis or in whom the duration of infection is unknown. Patients with penicillin allergy can be treated with alternative regimens if they have primary or secondary syphilis. Penicillin is the only effective drug for neurosyphilis; oral desensitization should be accomplished before treatment of penicillin-allergic patients. Other dilemmas may be encountered in the treatment of patients who have concurrent human immunodeficiency virus infection.
Perianal Streptococcal Dermatitis - Article
ABSTRACT: Perianal streptococcal dermatitis is a bright red, sharply demarcated rash that is caused by group A beta-hemolytic streptococci. Symptoms include perianal rash, itching and rectal pain; blood-streaked stools may also be seen in one third of patients. It primarily occurs in children between six months and 10 years of age and is often misdiagnosed and treated inappropriately. A rapid streptococcal test of suspicious areas can confirm the diagnosis. Routine skin culture is an alternative diagnostic aid. Treatment with amoxicillin or penicillin is effective. Follow-up is necessary, because recurrences are common.

ABSTRACT: Group B streptococcus is the leading cause of early-onset neonatal sepsis in the United States. Universal screening is recommended for pregnant women at 35 to 37 weeks’ gestation. The Centers for Disease Control and Prevention recently updated its guideline for the prevention of early-onset neonatal group B streptococcal disease. The new guideline contains six important changes. First, there is a recommendation to consider using sensitive nucleic acid amplification tests, rather than just routine cultures, for detection of group B streptococcus in rectal and vaginal specimens. Second, the colony count required to consider a urine specimen positive is at least 104 colony-forming units per mL. Third, the new guideline presents separate algorithms for management of preterm labor and preterm premature rupture of membranes, rather than a single algorithm for both conditions. Fourth, there are minor changes in the recommended dose of penicillin G for intrapartum chemoprophylaxis. Fifth, the guideline provides new recommendations about antibiotic regimens for women with penicillin allergy. Cefazolin is recommended for women with minor allergies. For those at serious risk of anaphylaxis, clindamycin is recommended if the organism is susceptible or if susceptibility is unknown, and vancomycin is recommended if there is clindamycin resistance. Finally, the new algorithm for secondary prevention of early-onset group B streptococcal disease in newborns should be applied to all infants, not only those at high risk of infection. The algorithm clarifies the extent of evaluation and duration of observation required for infants in different risk categories.
