Head trauma and cluster headache.

Post-traumatic cluster headache (CH) is a very rare occurrence. Only one such case has been verified in the literature thus far. On the other hand, a non-casual association is almost certain to exist between previous head trauma and future CH onset. Considering the generally long interval of time separating the two events, it is not easy to accurately explain the nature of the head trauma/CH relationship. Head trauma may damage extra- or intracranial peripheral or central nervous structures, hence predisposing to the future development of CH. However, there also is the possibility that previous head injuries may be more frequent among CH patients because of their lifestyle, which may leave them more exposed to the risk of traumatic events.

Cluster headache prevalence: methodological considerations. A review of the literature.

Cluster headache (CH), also known as "suicide headache", is characterized by a distinctive periodic temporal pattern and by accompanying autonomic symptoms during the attacks. Epidemiological data for the general population are scarce: only five studies have been carried out until now on CH prevalence in the general population, with conflicting results (prevalence rates vary between 56 and 326 cases every 100,000 inhabitants). Recently, a study was performed to investigate a representative sample of the Italian general population aged over 14 years. Possible CH cases according to the diagnostic criteria of the 1988 International Headache Society (IHS) classification were screened out of a sample of 10,071 patients registered in the lists of seven general practitioners (GPs) in Parma, using a previously validated, specially designed self-administered questionnaire. The diagnosis of CH was confirmed in 21 subjects (nine women and 12 men). The estimated prevalence rate was 279/100,000 (95% CI: 173-427), 227/100,000 (95% CI: 104-431) in women and 338/100,000 (95% CI: 175-592) in men. Based on methodological considerations, we believe that a lifetime prevalence rate of 279/100,000 for a population aged over 14 years is a reliable figure and it is probably not much lower than in the whole general population, since some studies performed on large case series have shown that the onset of CH is not frequent under 14 years of age.

Cluster headache prevalence in the Italian general population.

BACKGROUND: Prevalence of cluster headache (CH) is estimated at 56 to 69 per 100,000. OBJECTIVE: To calculate the CH lifetime prevalence in a sample representative of the Italian general population over age 14 years. METHODS: Possible CH cases according to the diagnostic criteria of the 1988 International Headache Society classification were screened from a sample of 10,071 patients (5,311 women and 4,760 men; mean age 50.4 years, SD 19.7 years) registered in the lists of seven Parma-based general practitioners (GPs), using a previously validated, specially designed, self-administered questionnaire. RESULTS: Seven thousand five hundred twenty-two subjects (74.7%; 3,971 women and 3,551 men; mean age 50.8 years, SD 19.0 years) responded to the questionnaire in their GP's office (n = 3,338; 1,885 women and 1,453 men) or at home by mail (n = 1,914; 1,030 women and 884 men) or by phone (n = 2,270; 1,056 women and 1,214 men). Of the 111 suspected cases (76 women and 35 men), 105 were seen by a neurologist and 6 were contacted on the phone. The diagnosis of CH was confirmed in 21 (9 women and 12 men), including 7 already followed at the authors' center for CH. Seventeen patients had episodic CH, and four (all men) had chronic CH. The estimated prevalence rate was 279 per 100,000 (95% CI 173 to 427), 227 per 100,000 (95% CI 104 to 431) in women, and 338 per 100,000 (95% CI 175 to 592) in men. CONCLUSION: These results point to a higher cluster headache lifetime prevalence than previous reports.

Behavior during cluster headache.

Cluster headache (CH), also known as "suicide headache," is characterized by a distinctive behavior during attacks. In 80% to 90% of cases, patients are restless and constantly moving in a vain attempt to relieve pain. They often perform complex, stereotyped actions. During attacks, CH sufferers do not want to be touched, stroked, or comforted and frequently moan a great deal, cry, or even scream. They sometimes indulge in violent, self-hurting behavior. Restlessness is a highly sensitive and highly specific parameter for CH and has been included among the signs and symptoms accompanying pain of the disorder in the Second Edition of the International Classification of Headache Disorders. A few hypotheses on pathophysiology of restlessness are addressed in this paper.

The De Barsy syndrome.

BACKGROUND: In 1968, De Barsy reported on a girl exhibiting an aged aspect, 'dwarfism, oligophrenia, and degeneration of the elastic tissue in cornea and skin'. The disorder was recognized as a subgroup of cutis laxa syndrome and termed De Barsy-Moens-Dierckx syndrome. The pathogenesis of the disorder is unknown. METHODS: To improve the comprehension of the pathogenetic mechanisms involved in the De Barsy syndrome, we performed an ultrastructural, morphometric, immunocytochemical study on a skin biopsy of a boy with the De Barsy phenotype, who has been clinically followed for 12 years from birth. Moreover, the lysyl oxidase activity was measured on skin fibroblasts cultured in vitro. RESULTS: Light and electron microscopy, morphometry, and immunocytochemical observations showed a significant reduction of the elastic fibers in the papillary and in the reticular dermis of patient compared to an age-matched control (p < 0.05). By contrast, the collagen structure, content, and the distribution were normal, as well as lysyl oxidase activity in the medium of in vitro fibroblasts (12,323 DPM/10(6) cells). The immunoreaction for antibodies recognizing fibrillin-1, neutrophilic elastase, and tumor necrosis factor-alpha was stronger, whereas that for antibodies against transforming growth factor-beta was less pronounced in the dermis of the De Barsy boy compared to control. CONCLUSIONS: Clinical, phenotypic, and structural data were consistent with the diagnosis of De Barsy syndrome. This is the first case described in Italy. Clinical and structural data confirm that the elastic component is mostly affected in this disorder. Moreover, ultrastructural and immunochemical findings suggest that both elastic fiber degradative and very likely synthetic processes are involved.

What predicts evolution from episodic to chronic cluster headache?

Over the last few years, attention has increasingly been focused on the evolution of cluster headache over time. Predictive factors have been identified that are correlated with an increased risk of unfavorable evolution from the episodic form to the chronic form of cluster headache. Late onset, the presence of sporadic attacks, a high frequency of cluster periods, and short-lived duration of remission periods when the headache is still in its episodic form all correlate with a possible worsening of the clinical picture over time. The reasons for evolution of episodic cluster headache to chronic are still unknown, but some factors, such as head trauma and other lifestyle factors--eg, cigarette smoking and alcohol intake--have been suggested as having a negative influence on the course of cluster headache over time.

Transient visual disturbances during migraine without aura attacks.

OBJECTIVE: To evaluate the prevalence and clinical features of transient visual disturbances (TVDs) during migraine without aura (MO) attacks and to point out any similarities with the disturbances listed among the diagnostic criteria of the International Headache Society (IHS) classification for migraine with aura (MA). METHODS: We studied a sample of 191 patients (145 women and 46 men) with MO and no other associated forms of primary headache who had been referred to the University of Parma Headache Centre between December 1, 1999 and December 1, 2000. RESULTS: A total of 165 patients reported that they had never experienced TVDs during their MO attacks. In the remaining 26 patients (19 women and 7 men), MO attacks were at times accompanied by TVDs, which were present in over 30% of MO attacks in 65.4% of patients. In about 60% of cases, TVDs lasted less than half a minute. TVDs consisted of phosphenes in most patients, general blurring of vision in about one-fourth, and scintillating scotomas in 15%. In 73% of cases, TVDs occurred during the headache phase, whereas in the remainder they preceded it. Strict application of the IHS diagnostic criteria would have led to a diagnosis of MA in 12 cases, corresponding to 46% of our MO patients with TVDs and to 6.3% of all patients with an established clinical diagnosis of MO. CONCLUSION: The results of our study suggest that current IHS diagnostic criteria for MA may lead to an overestimation of MA cases.

Upper and lower cluster headache: clinical and pathogenetic observations in 608 patients.

UNLABELLED: OBJECTIVE, BACKGROUND, AND METHODS: Ever since it was proposed by Ekbom and Kugelberg back in 1968 on the basis of the different location of head pain during attacks, the differentiation of cluster headache into an upper syndrome (US) and a lower syndrome (LS) has been regarded as a purely academic distinction. To evaluate whether this differentiation is indeed well founded and to understand its possible significance in the light of current pathogenetic knowledge, we rigorously applied Ekbom and Kugelberg's classification criteria to a sample of 608 patients with cluster headache (CH; 440 men and 168 women), including 483 with episodic CH, 69 with chronic CH, and 56 with CH periodicity undetermined. RESULTS: Of these patients, 278 could be classified as US sufferers and 330 as LS sufferers. Our data analysis showed statistically significant clinical differences between the two syndromes: pain location was more common in the ocular, temporal, and nuchal regions among LS sufferers; in addition, patients with LS reported not only a higher rate of autonomic symptoms, but also a higher predominance of nasal congestion, ptosis, and forehead and facial sweating among these symptoms. CONCLUSIONS: Based on current anatomofunctional knowledge and on the most recent pathogenetic findings, we believe that changes in hypothalamic activity posteroinferiorly may lead to activation of the caudal part of the spinal trigeminal nucleus by way of the hypothalamus, midbrain, and trigeminal nerve fibers and consequently to activation of the trigeminovascular system with a different location in the two syndromes. More specifically, there seems to be a larger and more extensive involvement of the subnucleus caudalis in LS compared with US, where only its ventrocaudal portions are likely to be affected.

Pain and behaviour in cluster headache. A prospective study and review of the literature.

Cluster headache (CH) has also been called "suicide headache" on account of the extremely severe pain that characterizes its attacks. It is indeed well known that CH sufferers exhibit peculiar behaviours during attacks. The purposes of our study were: i) to investigate prospectively prodromes and clinical pain features and behaviour of patients during typical, spontaneous attacks of CH defined according to the International Headache Society classification criteria; and ii) to investigate retrospectively the premonitory signs and symptoms preceding onset of the cluster period. Forty-two episodic CH patients consecutively referred to the University of Parma Headache Centre were asked to fill in a questionnaire soon after a "typical" CH attack. In the questionnaires, the patients were requested: a) to describe in their own words the type of pain experienced during the attack; b) to rate peak pain intensity on a visual analogue scale (VAS); c) to indicate the time elapsing between headache onset and peak pain intensity; d) to report the signs and symptoms preceding the attack (prodromes), choosing them from a 65-item list; and, e) to describe in their own words their behaviour during the attack. Each patient was also requested to report any signs and/or symptoms preceding onset of the cluster period (premonitory symptoms). Data analysis showed that the clinical features of pain were very complex and varied widely among patients. In 85.7% of cases, patients rated their peak pain intensity (reached on average within 8.9 minutes of attack onset) at between 8 and 10 on the VAS. Most (88.1%) exhibited typical signs of pyschomotor agitation (restlessness) during the attack. Prodromes were reported by almost all the patients in our sample (97.6%), and premonitory symptoms by only 40.5%. The results of our study suggest: i) that the pain in CH cannot be described either as vascular- or as neuralgic-type; ii) that a traditional three-item scale (mild, moderate, severe) does not allow adequate categorization of pain intensity, and should be replaced by the VAS in order to reflect a broader spectrum of pain intensity; iii) that restlessness during attacks is so frequent that it should become a CH diagnostic criterion; and, iv) that prompt and accurate reporting of prodromes and/or premonitory symptoms could be helpful in establishing early treatment.
