Sexually Transmitted Diseases

This infection is caused by reactivationof varicella-zoster virus (VZV),which may remain latent in thedorsal root and cranial nerve gangliafor decades. Reactivation oftenoccurs for no apparent reason, althoughstress and immunosuppressionmay increase the risk.

BOSTON -- A history of gonorrhea may translate into a twofold increased risk of bladder cancer for men, researchers here reported.

Liver disease, particularly hepatitis C, has emerged as a major cause of morbidity and mortality for people with HIV/AIDS in the era of potent antiretroviral therapy. Mortality is increased in patients with HIV–hepatitis C virus (HCV) coinfection compared with that in patients with HIV alone.1,2

Tinidazole (Tindamax), from PresuttiLaboratories, Inc., has been approvedfor treatment of trichomoniasis, giardiasis,intestinal amebiasis, and amebicliver abscess. A single 2-g doseis recommended for patients with trichomoniasisor giardiasis; in amebicdysentery, the recommended dosageis 2 g/d for 3 days. Patients with amebicabscess from amebic hepatitis require2 g/d for 3 to 5 days.

An estimated 20million Americansare currentlyinfectedwith humanpapillomavirus (HPV). Assuch, HPV is now the mostprevalent sexually transmitteddisease (STD) in thiscountry. Answers to commonquestions like the onesabove are therefore of particularinterest to physicians.The issue of when and howto use testing for HPV hasbecome especially crucial.

For nearly 3 years, my patient has had frequent recurrences (now, almost monthly)of erythematous, slightly pruritic lesions on the lower back, inguinal area, orbuttocks-but never on the genitalia.

For several months, a 26-year-old man has had persistent bumps on his scalpand the back of his neck. Some hair loss has also occurred at the site.

Accurate diagnosis of nonviralinfectious diseases ofthe vagina is largely contingenton the clinician’s abilityto do a sophisticated wetmount/potassium hydroxide (KOH)preparation examination-more specificallywhat is termed a “level II wetmount examination” (Table). Clinicalassessment in conjunction with a properwet mount/KOH analysis will usuallyidentify the causative organism orsuggest exclusion of diagnostic possibilities(Figure).

The emphasis in this clinically focused text is on syndromesand patient care rather than on pathogens. Among the topicscovered are antimicrobial pharmacokinetics and pharmacodynamics;head and neck infections; upper respiratory tractinfections; bronchitis and pneumonia; endocarditis; pericarditisand myocarditis; peritonitis, liver abscess, and biliary tractinfections; viral hepatitis; CNS infections; skin and soft tissueinfections; animal and human bites; osteomyelitis and infectiousarthritis; foot infections in patients with diabetes; scarletfever and toxic shock syndromes; fever of unknown origin;bacterial, viral, and protozoal diarrhea; obstetric-gynecologicinfections; urinary tract infections; sexually transmitted diseases;infectious complications of HIV infection; tuberculosis;tropical diseases; zoonoses; bioterrorism; and fungal infections.Color and black-and-white photographs, photomicrographs,CT scans, radiographs, drawings, tables, and flowchartshighlight seminal points in the text.

BOSTON -- An investigational immunomodulator has shown early antiviral activity in patients with difficult-to-treat chronic hepatitis C infections.

SEATTLE -- The human papillomavirus has a long racial memory. So concluded researchers here, who found that variants of two carcinogenic HPV types tend to linger longer in women whose ancestors came from the same area where the variants first arose.

A 24-year-old woman's first pregnancy was uneventful until the sixth month when mild malaise and a highly pruritic abdominal rash occurred. A biopsy and direct immunofluorescence confirmed the suspected diagnosis of herpes gestationis.

Extrahepatic manifestations of chronic hepatitis C virus (HCV) infection should prompt appropriate serologic investigation.

Rates of gonorrhea and chlamydial infection are highest among females 15 to 24 years old. Annual screening of all sexually active adolescents is warranted.

ROCHESTER, Minn. ?Treating obese patients with chronic hepatitis C infection with a diet-and-exercise regimen could improve both their overall health and their response to antiviral therapies, researchers suggest.

A 25-year-old man reports that he has had a swollen eye for thepast several days. He noticed a small amount of yellow discharge the previousevening. He denies systemic complaints, including fever, chills, nausea, vomiting,and recent trauma. He also tells you that he has a drip in my private area.

Some sexually transmitteddiseases (STDs), such assyphilis and gonorrhea, arecenturies-old scourges; othershave attained clinicalsignificance only in recent years.Despite the availability of effectivetherapy for many of these diseases,they remain an important publichealth problem.

The most common chronic blood-borne infection in the United States is caused by hepatitis C virus (HCV), an RNA virus transmitted through blood-to-blood contact. In this article, we identify risk factors for HCV infection and discuss which patients should be tested and treated.

You routinely order laboratory screeningpanels, including serum liver enzymemeasurements, for nearly everypatient who has a complete physicalexamination or who is seen for any ofa host of other complaints. If you findabnormal liver enzyme levels, your familiaritywith the common causes andthe settings in which they occur mayenable you to avoid costly diagnosticstudies or biopsy.
