Cerebral involvement in children with acute and relapsing inflammatory polyneuropathy

We present two children with seizures and other signs of cerebral involvement at the outset of acute inflammatory demyelinating polyneuropathy, consistent with a diagnosis of encephalomyeloradiculoneuropathy. One child had a recurrence associated with mild central dysfunction and improved during therapy with corticosteroids. Both children recovered completely. Both acute and relapsing inflammatory demyelinating neuropathy may be accompanied by cerebral dysfunction, expanding the clinical spectrum of encephalomyeloradiculoneuropathy.     

Periocular involvement in cutaneous leishmaniasis

OBJECTIVE: Although cutaneous leishmaniasis (CL) occurs mostly in the facial area, periocular involvement accounts for 2-5% of the facial lesions. CL lesions localized in the periocular region can easily be confused with various other diseases. The aim of this study was to examine the frequency of periocular involvement in CL in the Cukurova region of Turkey, as well as the clinical characteristics, diagnosis and methods of treatment of this disease. METHODS: Between December 1998 and December 2004, patients who were diagnosed with CL were evaluated prospectively with respect to periocular involvement. RESULTS: From the 2066 patients evaluated with CL, 2622 lesions were identified. In 59 (2.9%) of these patients, a total of 66 (2.5%) lesions were located in the periocular area. Thirty-two (48.5%) of these lesions were of the papular type, 15 (22.7%) the nodulo-ulcerative type, 10 (15.2%) the plaque type, and nine (13.6%) the nodular type. Dacryocystitis was identified in four patients with periocular involvement. Over the follow-up period, no ocular or periocular deformities or complications developed in these patients. CONCLUSION: Patients suspected of CL should be evaluated and treated early in the course of their disease to prevent any permanent ocular or periocular deformities.     

Effects of the antimigraine compound zolmitriptan ('Zomig') on psychomotor performance alone and in combination with diazepam in healthy volunteers

Zolmitriptan (Zomig^TM) is a 5HT_1B/1D agonist which has the ability to cross the intact blood-brain barrier to access central as well as peripheral receptors. Because of the potential for central nervous system side effects, this randomized, double-blind, placebo-controlled, 6-period crossover study evaluated the effects of 2.5 and 5 mg doses of zolmitriptan on psychomotor performance and investigated any pharmacodynamic or pharmacokinetic interaction with diazepam. Twelve healthy volunteers received the following "treatments" as single doses: zolmitriptan 2.5 mg, zolmitriptan 5 mg, diazepam 10 mg, zolmitriptan 2.5 mg+diazepam 10 mg, zolmitriptan 5 mg+diazepam 10 mg and placebo. Pre-dose and at 1, 4, 8, and 24 h post-dose, the following validated battery of psychomotor tests was performed: Bond-Lader visual analogue scales (calmness, contentedness, and alertness factors), critical flicker fusion test, choice reaction time (recognition, motor, and total reaction times), finger-tapping test, number cancellation test and digit symbol substitution test. Plasma concentrations of zolmitriptan, its active metabolite, and diazepam and its active metabolites were measured at the same timepoints. Zolmitriptan 2.5 and 5 mg had no effect on psychomotor function when given alone. In contrast, diazepam 10 mg had profound effects, consistent with its sedative properties, but there was no synergism on concomitant administration of either dose of zolmitriptan. Plasma concentrations of zolmitriptan, diazepam, and their respective active metabolites were similar when the two drugs were given alone or in combination.     

'To touch them, is to love them': effects of direct experience with condoms on adolescents' attitudes toward condoms

The present study examined the effect of a short physical interactionwith condoms (opening packages, taking out the condoms and unrollingthem) on the attitude toward condoms and on intended condomuse. Using a pre-post experimental design, 101 adolescents wererandomly assigned to one experimental and four control groups.Subjects in the experimental group handled condoms for about10 min, answering questions about the difficulty of performingthe instructed tasks. In the first control group, subjects completeda filler questionnaire on HIV infection. Subjects in a secondcontrol group watched a peer from the experimental group andanswered similar questions about the difficulty of performingthe tasks. The attention of subjects in the third control groupwas focused away from the features of condoms that are associatedwith their use; subjects were instructed to look at the condomsand complete a filler task. Subjects in a last control groupwere to observe subjects from Control group 3 and to completethe same filler task. Results indicated that having a short,direct experience with condoms failed to influence the attitudetoward condom use and intended condom use. Post hoc examinationof the effects in the control groups, however, suggested thatinducing an affective focus in subjects resulted in positiveattitudinal changes and had a positive effect on the expectationto use condoms in the future.
