than the fall in the number This can be attributed to the shift of the age-incidence pattern to an older age, when the risk of becoming a chronic carrier of HBsAg is smaller than in younger children. We have shown2 that the prevalence of HBV infections in Greek army recruits depends on the socioeconomic and educational level of their parents, which defines the hygienic and living conditions during childhood. Thus the reported significant decrease of HBV infections can be attributed to the considerable improvement of financial, socioeconomic, and living conditions in Greece during the past 20 years. We have also shown4 that, in contrast to some areas of South-East Asia, vertical HBV transmission does not have a significant role in Greece, since less than 5 % of the carrier pregnant women are
HBeAg positive. In view of these data
we
decided
against expanding routine
vaccination to newborn babies, until developments in recombinant DNA techniques and synthetic polypeptide vaccines provide more effective and considerably less extensive vaccines.s Our data also highlight the importance of national seroepidemiological surveys in decision making. Thus the results that Dr McMahon and colleagues report (Nov 14,1134) cannot and should not be directly extrapolated as a basis for practice in other areas of the world.

the patient was discharged in a satisfactory condition. Case C.-This child was admitted from a rural area 3 weeks later with clinical meningitis and CSF culture yielded group C N meningitidis with a penicillin MIC of 025 j.!gjmJ.2.3Treatment was I MU penicillin and 250 mg chloramphenicol intravenously every 6 h (despite the laboratory report). Temperature returned to normal by the 9th day and the child was discharged clinically well on the 11th
day. No contact between the patients or recent administration of antibiotic therapy could be established in any of the cases. Organisms were identified according to standard methods’ and MIC/minimum bactericidal concentrations were measured by replication on blood agar.Penicillinase activity was investigated by the chromogenic cephalosporin method’ in isolates from the first two cases but case C did not show p-lactamase activity. Attempts to type the p-lactamase and determine its plasmid were unsuccessful. This has been an exceptionally wet spring and N meningitidis notifications have been about five times the usual prevalence at this season. These are the first documented cases of penicillinaseproducing N meningitidis in Southern Africa.

third isolate showed diminished susceptibility (MIC 0-25
IJ.g/ml). Case A.-This 15-year-old girl presented with a history of severe headache and vomiting for 2 days. Other relatives were healthy. On examination she was confused,, had no fever, and pulse was 108/min, and she had neck stiffness with positive Kernig and Brudzinski signs. Culture of blood and cerebrospinal fluid (CSF) taken before the start of intravenous therapy for 10 days with 3 MU penicillin and 500 mg chloramphenicol both 6 hourly, yielded group C N meningitidis which was sensitive to chloramphenicol (Joan Stokes’ method)’ and resistant to penicillin. Gram-stain of centrifuged CSF demonstrated scanty unphagocytosed gramnegative diplococci. The patient improved clinically. However, her parents wished to consult a traditional doctor and the patient was discharged on oral 500 mg doses of amoxycillin every 8 hours despite the laboratory report of penicillin resistance. Case B.-This 2’-year-old boy presented 5 days later with a 1-day history of vomiting and coughing. His temperature was 39°C and he had neck stiffness and a red macular rash over the chest and both arms. Culture of CSF taken before 0 75 MU penicillin and 250

INJECTION PEN SiR,—The intracavemous injection of vasoactive drugs is fast
becoming the non-prosthetic treatment of choice for organic impotence.Ihave investigated the safety and efficacy of using an injection for this purpose. The pen injector, designed for insulin administration (’Insuject-X’; Nordisk Gentofte) is needle, syringe, and vial all in one. It weighs 30 g is 14-5cm long, and the cartridge has a replaceable 27G needle. The cartridge contains 2-5 ml of a mixture of 26 mg/ml papaverine hydrochloride with 1-3 mg/ml of phentolamine mesylate. The dose is pre-set, from 0-02 ml to 0 32 ml, by turning a grooved sleeve on the pen. A scale shows how much of the mixture is left. The pen can be carried discretely in a pocket and one cartridge will supply 10-15 doses. The needle must be changed between each injection. The injection is given by inserting the full length of the 10 mm needle into one cavernous body, The papaverine/phentolamine is expelled by turning the sleeve back to zero. Before’ injection a rubber band is placed round the base of the penis to prevent the escape of drugs and to ensure sufficient time for binding; the band is released after 5 min. When the cap is replaced on the pen after use the needle is automatically pulled out of the cartridge, preventing leakage and contamination. Eighteen men with erectile dysfunction were studied, 7 with neurogenic impotence (1vascular/neurogenic), and 11with undetermined organic impotence. They were asked to monitor the duration and function status of erection at home., All patients responded well to a dose of 0 08-0-32 ml. Erections sufficient for intercourse lasted 27-75 min, and there were no complications. The patients find the injection pen easier to use and more aesthetic than the traditional syringe and vial.
