The G and BBB syndromes: case presentations, genetics, and nosology.

Hypertelorism and hypospadias are described in four unrelated boys; bilateral cleft lip and cleft palate were also present in two of the boys and mild mental retardation in another. These features are compatible with both the G and BBB syndromes. When present, laryngotracheoesophageal anomalies or respiratory and swallowing difficulties are characteristic features of the G syndrome; otherwise facial features may be useful in distinguishing the G and BBB syndromes. Cases 1 and 2 had anteverted nares and a broad and flat nasal bridge, and Case 1 had shortened palpebral fissures, all consistent with the G syndrome. In contrast, Cases 3 and 4 had a high and broad nasal bridge as previously described in the BBB syndrome. The father of Case 1 had mild hypertelorism and first-degree hypospadias, demonstrating autosomal dominant inheritance in the G syndrome. The mothers of Cases 2, 3, and 4 all had mild hypertelorism consistent with autosomal dominant inheritance and partial male-sex limitation, as previously proposed for both the G and BBB syndromes.

Anterolateral rotatory instability of the knee joint. An early analysis of the Ellison procedure.

Our experience with the Ellison procedure for the control of anterior subluxation of the lateral tibial plateau includes fifty-two knees in which we used this procedure either alone or in combination with other reconstructive procedures. The results directly attributable to the Ellison procedure itself after follow-ups of six months or more could be evaluated in fifteen patients who had only the Ellison procedure for anterolateral instability and in thirteen who had both this procedure and a pes anserinus transfer for combined anterolateral and anteromedial instability. Of the twenty-eight patients so evaluated, only sixteen (57 per cent) had good or excellent results. The pivot-shift phenomenon, present in all twenty-eight knees preoperatively, had been eliminated in only four at follow-up. A positive anterior drawer sign was present in all patients both before operation and at follow-up. The subjective and functional improvement did not correlate well with the clinical and roentgenographic findings. From this study it is our impression that the results of this operation are disappointing and that it should be used only as an adjunctive procedure in lateral reconstruction in young patients.

New uses for benzoyl peroxide: a broad-spectrum antimicrobial agent.

Benzoyl peroxide is a useful agent in the treatment of acne, chronic ulcers, tinea pedis, and tinea versicolor, probably because of its antimicrobial power. 2.5% concentration is almost as active as 5%. Although potential irritancy and allergic reaction have not been a problem on the face, benzoyl peroxide should be used judiciously in chronically inflamed or ulcerated skin. Several potential uses are mentioned.

Failure of tyramine to induce migraine.

In a double-blind study of 80 migraine patients, headache was precipitated by ingestion of 200 mg tyramine and not by placebo in eight individuals, but retesting of seven of these patients did not produce the same results. Placebo produced as severe headache as tyramine and in an even larger number of patients. It is concluded that dietary tyramine alone is rarely, if ever, the major precipitant of a migraine attack, although the possibility remains that it has such a role in the presence of particular physiologic states.

Urinary ammonia and ammonia-producing microorganisms in infants with and without diaper dermatitis.

Free ammonia was determined in diaper squeezings from 26 infants with "ammoniacal dermatitis" and in 82 controls. No significant difference was found (402 ppm in diaper dermatitis compared to 465 in controls). The groups did not differ with regard to the incidence of organisms capable of splitting ammonia from urea. Experimental application of highly ammoniacal urine on intact infant and adult skin failed to provoke a dermatitis. Erythema could be induced only when ammoniacal urine was applied occlusively to scarified skin. These findings do not support the notion that ammonia is a primary factor in common diaper rash, but do not exclude a possible role for further irritation in an already existent condition.

Scabies masquerading as dermatitis herpetiformis.

Scabies can be easily mistaken for dermatitis herpetiformis because the two conditions have features in common, namely, pruritic papules, vesicles, and crusted erosions in the sacral and gluteal regions. In five patients with scabies who were initially judged clinically to have dermatitis herpetiformis, histological examination was decisive in the eventual correct diagnosis.

The syndrome of ectrodactyly, ectodermal dysplasia, and clefting (EEC).

Early recognition of ectrodactyly, ectodermal dysplasia, and clefting of the lip and palate as a syndrome could result in more beneficial treatment for the patient. Patients with the EEC syndrome often have ocular and auricular deficiencies that progressively become more severe. These patients are often seen first by cleft palate teams who make the diagnosis. The patient's dental status requires frequent evaluation after corrective procedures for cleft lip and cleft palate.
