[Bilateral facial palsy following pulmonary infection--a possible variant of acute inflammatory polyradiculoneuropathy]. / Bilaterale Fazialisparese nach Lungeninfektion--eine mögliche Variante einer akuten inflammatorischen Polyradikuloneuropathie.

HISTORY AND CLINICAL FINDINGS: A 43-year old female presented with bilateral facial muscle weakness a month after onset of upper respiratory tract infection. INVESTIGATIONS: The neurologic examination on admission revealed bilateral facial palsy, no signs of muscular weakness, hyperreflexia and flexor plantar responses. Extensive laboratory analysis, radiological and neuroimaging assessment were unremarkable but analysis of cerebrospinal fluid revealed albumin-cytological dissociation. Sequentially, nerve conduction studies confirmed demyelination of both facial nerves. A diagnosis of Guillain-Barré syndrome was made according to clinical findings, laboratory results and nerve study results. TREATMENT AND COURSE: IVIg therapy was initiated (2 g/kg per 5 days) after no response to tapered intravenous corticosteroid therapy. Five days after the last IVIg dose the patient started to recover. Both eyes were treated with standard protective measures. CONCLUSION: Guillain-Barré syndrome is an acute autoimmune polyneuropathy characterized by a course of rapid ascending muscular weakness and mild sensory symptoms appearing approximately two-four weeks after an infection. The facial nerve is of all cranial nerves most often affected but it is rarely the prominent sign of GBS. As well, bilateral facial palsy has never been described as a sole manifestation of GBS, as of our notion.

Migraine and tension-type headache in Croatia: a population-based survey of precipitating factors.

The careful monitoring of the trigger factors of headache could be an important step in treatment, because their avoidance may lessen the frequency and severity of attacks. Furthermore, they may provide a clue to the aetiology of headache. The aim of the present study was to estimate the prevalence of tension-type headache (TTH) and to establish the frequency of precipitating factors in subjects with migraine and TTH in the adult population of Bakar, County of the Coast and Gorski Kotar, Croatia. Another important purpose of the study was to examine the relationship of the precipitating factors with migraine and TTH, and with migraine subtypes: migraine with aura (MA) and migraine without aura (MO). We performed a population-based survey using a 'face-to-face door-to-door' interview method. The surveyed population consisted of 5173 residents aged between 15 and 65 years. The 3794 participants (73.3%) were screened for headache history according to the International Headache Society (IHS) criteria. Headache screen-positive responders, 2475 (65.2%), were interviewed by trained medical students with a structured detailed interview focused on the precipitating factors. The following precipitating factors in lifetime migraineurs and tension-type headachers have been assessed: stress, sleep disturbances, eating habits, menstrual cycle, oral contraceptives, food items, afferent stimulation, changes in weather conditions and temperature, frequent travelling and physical activity. A total of 720 lifetime migraineurs and 1319 tension-type headachers have been identified. The most common precipitants for both migraine and TTH were stress and frequent travelling. Stress (odds ratio (OR) 1.4, 95% confidence interval (CI) 1.17, 1.69) was associated with migraine, whereas physical activity (OR 0.72, 95% CI 0.59, 0.87) was related to TTH. Considering MA and MO, frequent travelling (OR 2.2, 95% CI 1.59, 2.99), food items (OR 2.2, 95% CI 1.35, 3.51) and changes in weather conditions and temperature (OR 1.75, 95% CI 1.27, 2.41) exhibited a significant positive association with MA. The present study demonstrated that precipitant-dependent attacks are frequent among both migraineurs and tension-type headachers. Lifetime migraineurs experienced headache attacks preceded by triggering factors more frequently than tension-type headachers. MA was more frequently associated with precipitating factors than MO. We suggest that some triggering factors may contribute to the higher occurrence of precipitant-dependent headache attacks in susceptible individuals.

Prevalence of migraine in Croatia: a population-based survey.

OBJECTIVES: The aim of the present study was to estimate the prevalence of migraine among Croatian adults. This is the first epidemiological study of migraine in Croatia in which the operational diagnostic criteria of the International Headache Society have been applied. METHODS: The study population consisted of all residents (aged 15 to 65 years) of Bakar, County of The Coast and Gorski Kotar, Croatia. A population-based survey was undertaken using a "face-to-face, door-to-door" interview METHOD: The participation rate was 73.3%. All participants were screened for headache history according to the International Headache Society criteria. Headache screen positive responders (65.7%) were interviewed by trained medical students with a structured detailed interview focused on migraine. RESULTS: A total of 720 lifetime migraineurs were identified. The lifetime prevalence of migraine was 22.9% (95% confidence interval, 20.9 to 25.1) in women, 14.8% (95% confidence interval, 13.1 to 16.8) in men, and 19% (95% confidence interval, 17.6 to 20.5) in both sexes. The highest lifetime prevalence of migraine was in women in the age group 40 to 49 years (38.1%). Among 636 active migraineurs, 399 (62.7%) were women and 237 (37.3%) were men; 55.8% had migraine without aura, 35.2% migraine with aura, and 6.9% migraine both with and without aura. The 1-year prevalence of migraine, migraine without aura, migraine with aura, and migraine both with and without aura in women was 18%, 11.3%, 8.6%, and 2.2%, respectively. In men, the 1-year prevalence of migraine, migraine without aura, migraine with aura, and migraine both with and without aura was 12.3%, 7.3%, 3%, and 0.7%, respectively. CONCLUSIONS: The prevalence of migraine in this Croatian population showed rates quite similar to those reported in neighboring countries, such as Italy and France. Further studies are needed to estimate the prevalence rates of migraine in the total Croatian population.
