The treatment of acne vulgaris with low dosage doxycycline.

Doxycycline hyclate 20 mg bid is an effective maintenance dosage in patients with inflammatory acne. Twelve subjects aged 14 to 36, both men and women, completed a 16-week study to demonstrate the effectiveness of submicrobial dosing of doxycycline hyclate. Seventeen subjects were screened, and three withdrew before receiving any medication. The subjects received doxycycline hyclate 100 mg daily for eight weeks. One subject withdrew due to unrelated side effects. Eleven subjects had a 50% reduction of lesions at eight weeks, which qualified them to enter the second eight-week phase of the study. This group received either doxycycline hyclate 20 mg bid or placebo. The six subjects receiving doxycycline hyclate 20 mg bid maintained their improvement, while the placebo group did not.

Traumatic purpuric penile ulcer.

A 33-year-old man presented with a history of a penile ulcer of four days' duration. He was immediately treated with 2.4 million IU of benzathine penicillin IM and tested for syphilis, but subsequently proved non-reactive. He was already receiving doxycycline BID from another physician for this nonspecific genital ulcer and minocycline for acne. Past medical history revealed periodic flares of hidradenitis suppurativa, limited to the buttocks and inguinal region; acne, involving the face and back; and angiokeratoma of the scrotum. He had no known drug allergies, nor had he admitted to taking any other medicaments. Examination revealed an 8 x 15 mm irregularly shaped, shallow, tender ulcer over a larger purpuric base and involving part of the corona and the distal portion of the shaft. No inguinal adenopathy or buboes could be found on palpation. The patient was placed on a cream containing 3% iodochlorhydroxyquin 1% hydrocortisone. By the end of two weeks of therapy, the lesion had healed with no residual discoloration. Subsequently, the patient revealed that he masturbated daily, rubbing his penis back and forth on the bed sheet while lying prone on the bed. Eleven months later, he consulted us again for a new purpuric penile ulcer, because he had begun to masturbate in his usual fashion. The ulcer healed within several days, and there were no sequellae.

Commercial preparations and handling of botulinum toxin type A and type B.

The recognition of botulinum toxin as a therapeutic tool has revolutionized the approach to facial esthetics. In the 1970s, Dr. Alan B. Scott pioneered the use of botulinum toxin type A (BTX-A) for strabismus. This discovery led to further studies examining other clinical applications of BTX-A and, more recently, botulinum toxin type B (BTX-B). Despite its widespread use and the more than two decades of experience with BTX-A, controversy remains over the preparation and handling of the toxin.

Impetigo herpetiformis.

Impetigo herpetiformis is a rare pustular disorder that occurs primarily in pregnancy and is often associated with hypocalcemia. The onset commonly presents in the last trimester of pregnancy; the condition may persist until delivery and it rarely continues in the postpartum period. There is an increase in morbidity and mortality for the mother and the fetus. As a result, immediate diagnosis and treatment is crucial. The purpose of this article is to delineate the clinical picture of this disease, its treatment, and the effect on the mother and the fetus.
