Dysfunction of the pupillary light reflex following migraine headache

Using pupillometry and sympathetic skin responses we compared the changes in local and systemic autonomic function within one week of a migraine attack. We investigated whether the measurement of the pupillary light reflex provides further information on the pathophysiology of migraine. Forty-two migraine patients and forty-two healthy age-matched controls were included. The parameters that were measured were the amplitude of the pupillary light reflex, the pupil size at the beginning of the measurement, the latency, the velocity of constriction and the velocity at the end of the dilatation. The average pupil size was 6.43 mm in the migraine group and 6.7 mm in the control group (p < 0.01). Reduced velocity of constriction and smaller amplitude of constriction in migraine patients within two days of an attack were signs of a parasympathetic dysfunction (p < 0.05). The sympathetic skin response did not differ significantly between migraine sufferers and controls. These findings indicate that both parasympathetic and sympathetic nerves supplying the eye are involved in migraine headache presumably due to effects on the pericarotid sympathetic fibers and involvement of trigeminal-parasympathetic reflexes.

The natural course of DSM-IV somatoform disorders and syndromes among adolescents and young adults: a prospective-longitudinal community study.

OBJECTIVE: Although somatoform disorders are assumed to be chronic clinical conditions, epidemiological knowledge on their natural course based on representative samples is not available. METHOD: Data come from a prospective epidemiologic study of adolescents and young adults in Munich, Germany. Respondents' diagnoses (N = 2548) at baseline and follow-up on average 42 months later are considered. The follow-up incidence, stability as well as selected baseline risk factors (sociodemographics, psychopathology, trauma exposure) for the incidence and stability of somatoform disorders and syndromes are prospectively examined. Diagnostic information was assessed by using the standardized Munich-Composite International Diagnostic Interview (M-CIDI). RESULTS: Over the follow-up period, incidence rate for any of the covered somatoform diagnoses was 25.7%. Stability for the overall group of any somatoform disorder/syndrome was 48%. Female gender, lower social class, the experience of any substance use, anxiety and affective disorder as well as the experience of traumatic sexual and physical threat events predicted new onsets of somatoform conditions, while stability was predicted by being female, prior existing substance use, affective and eating disorders as well as the experience of a serious accident. CONCLUSIONS: At least for a substantial proportion of individuals, the overall picture of somatization seems to be relatively stable, but with fluctuation in the symptom picture over time. Being female, the experience of substance use as well as anxiety disorder seem to constitute risk factors for the onset of new somatoform conditions as well as for a stable course over time.     

Repressiveness: Cause or result of cancer?

Repression is commonly assumed to be a major characteristic of the cancer-prone personality. Main supporting evidence includes studies showing that cancer patients are low in emotional expression and that repressives have shorter survival. The evidence did not seem compelling, mainly because of contrary findings, overlooking the age factor and the assessment instruments. Thus, we examined whether repression is a response to the threat posed by the cancer diagnosis and whether cancer patients are more repressive, using a new assessment method combining anxiety and defensiveness scores and controlling age. The subjects were 98 women comprising three groups comparable in demographic characteristics: (a) breast biopsy showed they were healthy (n = 40), (b) biopsy showed they had breast cancer (n = 32), and (c) underwent surgery unrelated to cancer (n = 26). Only post-surgery groups a and b knew the diagnosis. Questionnaires of information and repression were administered to all women pre- and post-surgery. Before surgery, the groups did not differ in repression, anxiety and defensiveness. Post-surgery, there were no differences in anxiety but MANOVA and X² analyses showed that, in the malignancy group, defensiveness and the number of repressors increased more than in the other groups. The results indicate that repression could be a response to the threat posed by the cancer diagnosis and a means for keeping anxiety at a tolerable level rather than a personality trait of cancer patients.     

Aktuelles zum Thema Latex-Allergie

Zusammenfassung Die Typ I-Allergien gegen Latex sind in den vergangenen Jahren zu einem zunehmenden berufsdermatologischen Problem geworden, zumal mindestens 10% der Angestellten im Gesundheitswesen betroffen sind. In der Dermatologischen Klinik der Universit?t Erlangen-Nürnberg stieg die Anzahl der j?hrlich diagnostizierten Patienten mit Latexallergien von 1989 bis 1995 auf das 12fache, wobei der Anteil der schweren, generalisierten Formen der Erkrankung von 10,7% (1989/1990) auf 44% (1994/1995) zunahm. Unter den m?glichen Ausl?sern der Latexallergie (wasserl?sliche Proteine mit Molekulargewichten von 2 bis 200 kD) sind mindestens 5 Hauptproteine mit bereits bekannter Prim?rstruktur zu berücksichtigen. Zus?tzlich gibt es Hinweise für Markerproteine, die in bestimmten Risikogruppen geh?uft zur Ausl?sung spezifischer IgE-Antik?rper führen (z.B. 46 kD-Protein in medizinischen Berufen, 14,6 kD- und 27 kD-Proteine bei Kindern mit Spina bifida). Das Vorkommen von Kreuzreaktionen zwischen Latex und unterschiedlichen Früchten (besonders Avocado, Kiwi, Banane, E?kastanie) bei 60 bis 70% der Latexallergiker ist bei der allergologischen Abkl?rung und Beratung dieser Patienten zu beachten. Wesentliche Aspekte der Prophylaxe umfassen die konsequente Umstellung medizinischer Einrichtungen auf ungepuderte Latexhandschuhe mit niedrigem Proteingehalt. Eine Zusammenstellung von OP- und Untersuchungshandschuhen, welche Angaben über die von uns ermittelten Proteinkonzentrationen (modifizierte Lowry-Methode und Hochdruck-Flüssigkeits-Chromatographie, HPLC) enth?lt, soll ein Leitfaden bei der Auswahl allergologisch geeigneter Handschuhe sein.

Lymphangiosarcoma in late-onset hereditary lymphedema: Case report and nosological implications

Hereditary lymphedemas that are not associated with other malformations usually affect the lower limbs and are inherited in an autosomal dominant fashion. These non-syndromic hereditary lymphedemas are categorized by their age of onset, being either congenital (Milroy disease) or having an onset in childhood or around puberty (Meige disease). We describe a family in which three individuals in three generations had unusually late onset of lym-phedema in their mid-twenties or thirties. The proband additionally developed a very rare lymphangiosarcoma. This tumor, usually associated with post-mastectomy lym-phedema, has not been described in late-onset hereditary lymphedema. Because of an unusually high incidence of multiple primary tumors in association with lymphangiosarcoma in the literature (approximately 10%) and the proband's own familial cancer background, we speculate that an inherited predisposition to malignancy may underlie the development of lymphedema-associated lymphangiosarcoma. © 1995 Wiley-Liss, Inc.     

Posterior dislocation of the sternoclavicular joint: report of two cases,with emphasis on radiologic management and early diagnosis

Posterior dislocations of the sternoclavicular joint are uncommon, but are potentially quite serious. Radiologic diagnosis and management are frequently difficult. The specialized projections available are not widely known, and the role of plain films is poorly understood. The incidence, pathomechanics, and clinical manifestations of such dislocations are presented and the radiologic diagnosis is discussed.     

An analysis of fluid loss during transcervical resection of submucous myomas

Objective: To determine the contribution of several variables to fluid loss during transcervical resection of submucous myomas.Design: An observational study using multiple linear regression analyses.Setting: A university-affiliated training hospital and a university department of clinical epidemiology and biostatistics.Patient(s): Patients with submucous myomas.Intervention(s): Transcervical resection of submucous myomas and monitoring of fluid loss.Main Outcome Measure(s): Patient age, uterine enlargement, treatment with GnRH analogues or 8-ornithine-vasopressin, type of anesthesia, number of myomas, intramural extension of the myoma (type of myoma), and operating time were tested as variables.Result(s): Only intramural extension of the myoma and operating time were obviously related to fluid loss. For the other variables, such a relation was weak at best. The relation between fluid loss and operating time was not modified by any of the other variables.Conclusion(s): Because fluid loss is an important limiting factor in the transcervical resection of submucous myomas, special attention should be paid to reduction of the operating time and preoperative assessment of the intramural extension of the myoma to guide appropriate patient selection.
