Childhood onset cluster headaches.

Cluster headaches are rare in childhood. We identified 35 patients with cluster headaches starting at or before 18 years of age, including 7 patients with onset prior to age 10. All patients met the criteria of the International Headache Society for episodic or chronic cluster headaches. Patients experienced cluster headaches for as long as 20 years before seeking medical attention and required many medical contacts to establish the correct diagnosis. The clinical features of cluster headaches during childhood were similar to those which typically occur in adult life. Cluster headache patterns changed over 18 years of follow up. The frequency and duration of cluster periods increased in 14 subjects. The frequency of single headache attacks during cluster periods also increased in a similar number of subjects. We conclude that cluster headaches starting in childhood or adolescence closely resemble the adult form of the disease. In many patients, the frequency and duration of cluster periods and the frequency of the individual headache episodes increased over time. Cluster headache represent a treatable under-recognized cause of severe headaches in childhood and adolescence.

Chronic pain syndromes and their treatment. I. Cluster headache.

Cluster headache is a form of unilateral headache which, in the past, has been very resistant to treatment. Lithium carbonate has been shown to be the only reliably effective treatment in this condition and, although only a few cases have so far been reported in the literature they have, with very few exceptions, been successful. Therefore we selected five patients who at one time or another had presented with cluster headache and who had no relief from conventional treatment, and treated them with lithium carbonate. This has been highly successful. Some patients who had suffered from the disease for many years have been completely or almost completely relieved of their affliction, while others have been markedly improved to the point where they can now function normally, both socially and professionally. The possible modes of action of lithium in this condition are discussed.

Ophthalmic presentations of cluster headache.

Cluster headache is frequently characterized by pain localized to the orbital area. There is often associated ipsilateral oculosympathetic paresis with varying degrees of blepharoptosis and miosis. The ophthalmologist is often confronted with such cases; however, the atypical presentations and the subtle clinical findings may obscure the diagnosis. As cluster headache is a benign condition, accurate recognition is essential to spare the patient potentially harmful diagnostic studies.

Cerebrospinal fluid pressure and venous pressure in "dynamite headache" and cluster headache attacks.

Six patients with episodic cluster headache were investigated as to blood pressure, heart rate, cerebrospinal fluid pressure (Pcsf) and frontal vein pressure (Pvf) during five nitroglycerin (NG) provoked attacks and one spontaneous attack. In a seventh studied patient the NG failed to provoke an attack. The earlier reported decrease of systolic blood pressure and increase of diastolic blood pressure and heart rate after NG administration were also found in these patients. The "dynamite headache" was related to the start and duration of an increase of the cerebrospinal fluid pressure. There was no relationship between the start or the maximum pain of the cluster headache attack and changes in Pcsf or Pvf. On breathing oxygen during a cluster headache attack, there was a decrease of Pcsf but in some patients a temporary increase of Pvf was observed, which possibly indicates that oxygen simultaneously attains constriction of arteries and veins.

Cluster headache.

Cluster headache is a relatively common form of vascular headache. Its characteristic clinical pattern should allow definitive diagnosis in the vast majority of cases. Extensive diagnostic evaluations are not indicated. Treatment is generally unsatisfactory but helpful in a number of cases. It has a limited natural history and is essentially a benign condition.

Immunological alterations in cluster headache during remission and cluster period. Comparison with low back pain patients.

Cluster headache is a disorder of unknown origin. Some studies have focused their attention on neuroendocrine derangement, others on immunity. To probe central alterations in cluster headache (CH), immune parameters were investigated in cluster headache patients in comparison to low back pain patients and healthy controls. Increases in peripheral blood monocytes found in remission cluster headache patients may be attributable to chronic central nervous system (hypothalamic?) noradrenergic dysfunction or altered beta-endorphin. Alterations in NK+, CD3+ and CD4+ levels found in cluster period cluster headache and low back pain patients are probably pain or stress-related.

MRI of intracranial arteries in nitroglycerin induced cluster headache attacks.

Eight patients with episodic cluster headache, five in active episode, three out of episode, were investigated as to diameters of intracranial arteries before and after nitroglycerin (NG) administration. The diameter of all intracranial carotids were increased about 10 minutes after NG, although more in the patients in episode than in patients out of episode. The dilatation remained for the next 60 minutes in the patients who did not get a cluster headache attack. There was a normalization of the diameters of the internal carotid arteries compared to the initial values, at maximum pain in all patients who got a cluster headache attack. Similar changes were also found in the basilar arteries. The findings support the hypothesis of a constriction of intracranial arteries at maximum pain in cluster headache attacks to stop the pain.

Cerebral Arteries

Cluster headache syndrome and migrain. Ophthalmological support for a two-entity theory.

Patients suffering from migraine, cluster headache and atypical cluster headache, including patients with chronic paroxysmal hemicrania, were studied with respect to corneal temperature, intraocular pressure and corneal indentation pulse amplitude changes during pain attacks. Significant rises in these three parameters were deomonstrated during attacks of cluster headache and atypical cluster headache, indicating that intraocular vasodilation with increased ocular blood flow occurs during attacks. No definite changes were found in migraine. The results strongly suggest that significant pathophysiological differences exist between migraine and cluster headache. The point is stressed that these disorders probably represent separate pathogenetic entities and should be classified as such, and not be grouped together within an ill-defined group of "vascular headache".

Ipsilateral cluster headache and chronic paroxysmal hemicrania: two case reports.

We report two patients with ipsilateral attacks of cluster headache and chronic paroxysmal hemicrania. The first patient, a 33-year-old man, started having attacks of chronic cluster headache at the age of 27. At 33, they were replaced by typical attacks of ipsilateral chronic paroxysmal hemicrania which showed a dramatic improvement with indomethacin 150 mg daily. After two days of complete remission, cluster headache attacks reappeared and persisted until verapamil, 360 mg a day, was added to indomethacin. The second patient, a 45-year-old man, first developed attacks of episodic cluster headache at the age of 35. At 44, he experienced ipsilateral typical attacks of chronic paroxysmal hemicrania, and two months later attacks of cluster headache. Under verapamil 240 mg daily, attacks of cluster headache disappeared, but those of chronic paroxysmal hemicrania increased in frequency until indomethacin 150 mg daily was added. These observations suggest a close relationship but not a similarity between cluster headache and chronic paraoxysmal hemicrania, and show the practical therapeutic interest of maintaining this distinction.

Cluster headache, hemicrania, and other head pains: morbidity of carotid endarterectomy.

Carotid endarterectomy has become a widely used approach to the treatment of cerebrovascular disease. In spite of increasing experience, a significant and varied morbidity remains attached to the procedure. A poorly recognized complication is postoperative headache. In a series of 57 endarterectomies in 50 patients, 24 patients experienced postoperative headaches encompassing the entire spectrum of vascular headaches: nonspecific diffuse headaches, severe hemicranias, cluster headaches occurring early and delayed, chronic paroxysmal hemicranias, carotidynia, and Eagle's syndrome. Five patients had hemicranias, and all were homolateral to the endarterectomy. Therefore, we hypothesize that the spontaneously occurring hemicranias, the counterparts of postsurgical headache syndromes, also may be due to some overt or occult injury or disease of the carotid vessels or carotid sheaths in the regions from the carotid bifurcation to the base of the skull.

[Immunohistochemical profile of the nasal mucosa during the acute phase of cluster headache].

We studied 20 patients with cluster headache (11 males, 9 females) and 10 subjects free from this disorder. Nasal cavities were endoscopically studied to evaluate the mucociliary transport, pH, IgG, IgA and IgM levels in nasal secretion and in serum, and Na, K and Cl serum levels. We observed in all patients in the study group in comparison with the control group an increase of pH, and of serum IgA and IgM levels (but not of IgG). Na, K, and Cl serum levels in the patients with cluster headache were lower than those in the control subjects.

Acute Disease

Orbital phlebography: a comparison between cluster headache and other headaches.

Orbital phlebography has previously been found to be pathologic in 8 of 13 patients with episodic cluster headache. To compare the frequency and pattern of the pathologic findings in cluster headache with those in other headache categories, orbital phlebographies were carried out in patients with cluster headache, cervicogenic headache, migraine and tension-type headache (tension headache). The investigations were evaluated independently by two radiologists, one of whom had no knowledge of the diagnoses. The frequencies of pathologic findings were at maximal 2/12 in the cluster headache group, 2/11 in the cervicogenic headache group, 5/12 in the migraine group and 5/15 in the tension-type headache group. The investigators agreed completely in the evaluation of 39/50 phlebograms, with lesser disagreements in 7. In conclusion, the frequency of pathologic findings at orbital phlebography in cluster headache was not higher than in the other diagnostic categories investigated, and the pattern of the pathology was generally the same.

Corneal sensitivity during and outside attacks of cluster headache.

Corneal sensitivity has been studied in cluster headache (n = 38) and controls (n = 16). The patients were studied either during remission (n = 20), interparoxysmally in a bout (n = 17), or during attacks (spontaneously occurring attacks (n = 5) and nitroglycerin-provoked attacks (n = 6). For the measurements, a Cochet-Bonnet esthesiometer was utilized. This esthesiometer has a 6 cm long, adjustable nylon monofilament, which can be reduced in length by 0.5 cm at a time, the length of the filament determining the pressure exerted onto the corneal surface. All controls sensed the pressure at 6.0 cm filament length. In 5 cluster headache patients (remission, n = 4; cluster period, n = 1) a slight reduction in corneal sensitivity was found. No statistical difference was, however, found between any of the groups tested, and there was no asymmetry as far as averages were concerned.

Cluster headache associated with primary hyperlipidemia.

Two brothers suffering from cluster headache of the chronic variant as well as hyperlipidemia are described. The mother very likely suffered from the same combination. Eleven consecutive cases of cluster headache were studied for lipid abnormalities. Among five patients of the intermittent type, one suffereed from xantelasmata but had normal blood lipids. Among six patients of the chronic variant two had essential hyperlipidemia type IV. An etiological relationship between some cases of cluster headache and hyperlipidemia is therefore suggested.

[The cluster headache: a clinical model of immunologic receptor pathology?].

It is well established that cluster headache shows impaired functions at their neuroimmunomodulatory system level. Defect in receptor expression for 5-HT, IL-1 and IL-2 have been found in these patients. Sumatriptan, a molecule with agonistic activity for 5-HT1D receptor, truncates cluster headache attacks in 74% of patients. Flow cytometric analysis of monocytes expressing 5-HT receptor in cluster headache patients showed different trends clearly correlated with the clinical response to sumatriptan. Our findings strongly support the concept that cluster headache patients who are non responders to sumatriptan could present a block in their 5-HT receptor possibly due to specific autoantibodies for this receptor site.
