[Headache in the general practice]. / Kopfschmerzen in der Hausarztpraxis.

Headaches are one of the most frequent causes of consultations in general practice. Of more than 350 known headache tendencies, tension-type headache and migraine are particularly common in general practice. Medication overuse headache (MOH) is also common but rarely diagnosed. The medical consultation with a targeted anamnesis is the cornerstone of the diagnosis and correct classification. A detailed neurological examination completes the basic diagnosis. Additional laboratory and instrumental diagnostics follow in cases of atypical headache or clinical suspicion of secondary headache. This article focuses on the diagnosis and treatment of Tension-type Headache, migraine and Medication Overuse Headache.

Differentiation of subgroups of monosymptomatic enuresis according to prepulse inhibition of the startle reflex.

AIM: Monosymptomatic enuresis (ME) is a common disorder in children with serious social and psychological consequences. Treatment is usually initiated with desamino-arginine vasopressin (dDAVP) and/or alarm therapy as first-line treatment and imipramine as second-line. All treatments have proven efficacy, but are not successful with all patients. Therefore, a differentiation into subgroups according to treatment efficacy would be beneficial. METHODS: A group of patients resistant to first-line treatment was treated with imipramine and compared with matched controls successfully treated with dDAVP and/or alarm therapy. Prepulse inhibition (PPI) to acoustic startle reflexes was measured in all patients. RESULTS: In a group of 23 nonresponders, the median PPI was 72% (range 43-94%) compared with the matched dDAVP/alarm - responders with a median PPI of 26% (range 0-61%) (p < 0.0001). The response rate to imipramine was 87%. CONCLUSION: The presented data provide evidence that PPI allows to identify two subgroups of ME. The results offer further insight into (at least) two different pathomechanisms involved in ME: (i) a maturational delay of reflex inhibition with reduced PPI and (ii) a normal PPI, possibly with abnormal sleep patterns, that can be influenced by imipramine.
