The etiology of nasal polyposis is still unknown, although risk factors include Aspirin intolerance, asthma, cystic fibrosis and primary ciliary dyskinesia. We studied frequencies of HLA A, B, DR and DQ in patients with nasal polyposis in order to determine a possible genetic component in the multifactorial pathogenesis of nasal polyps. Previous work has suggested an association of HLA-A1B8 with nasal polyposis and Aspirin intolerance. We investigated 89 patients with nasal polyposis, 11 of whom had Aspirin-intolerance, 19 asthma and 22 allergies to inhalation allergens. HLA patterns of these patients were compared to the ones of 1,070 healthy controls. No significant association of HLA-A1B8 was found with nasal polyps in the Aspirin-sensitive subgroup of our patients, but a significant association was seen with HLA-A74 and nasal polyposis.

The effectiveness and safety of ceftriaxone and cefotaxime in the short-term treatment of primary bacterial meningitis were compared using a prospective, randomized, multicenter study design. Children between the ages of 6 weeks and 16 years received either ceftriaxone as a single dose (100 mg/kg on the first day followed by 75 mg/kg/day) or cefotaxime as four divided doses (200 mg/kg/day) for 4–7 days. A total of 82 patients (44 ceftriaxone, 38 cefotaxime) with documented bacteria in the CSF were studied. In patients receiving ceftriaxone, full recovery occurred in 79.5% while a further 13.7% recovered with neurologic sequelae. Full recovery was observed in 71.1% of children treated with cefotaxime with sequelae in a further 23.6% (no statistically significant differences between drugs). The time to clinical improvement and resolution of fever (3–4 days) was also similar for both drugs. All but 1 of the 82 patients studied had negative CSF cultures within 24 h of the beginning of therapy consistent with the excellent penetration into the CSF (trough concentrations of 2.7 mg/l for both drugs at the end of therapy). No differences were observed in the incidence of clinically significant adverse events. Ceftriaxone and cefotaxime are both effective in the treatment of bacterial meningitis. Ceftriaxone offers an advantage in ease of administration since it is administered as a single daily dose.

Curative treatment can be achieved by timely and complete resection of verrucous carcinoma of the skin, even in advanced cases.
