Migraine is a variant of headache often associated with neurologic and/or vegetative symptoms mainly represented by abdominal pain. This symptom may occur some hours before migraine manifestation and in these cases the differential diagnosis with other clinical conditions characterized by abdominal pain, which is very common during childhood, may be difficult. Abdominal migraine can be diagnosed only if a close relationship is demonstrated between the abdominal symptoms and migraine. Alteration of consciousness is a well known feature during migraine and in some cases EEG may show SNC involvement during the attack. We report a case of abdominal migraine attack evaluated by EEG. The patient, a 10 years old male, presented with a picture of acute abdomen. An EEG performed at the occurrence of the early headache symptoms and of consciousness alteration demonstrated a pattern characterized by a lowering in the electric activity on the left hemisphere. Some hours later he developed a clear migraine followed by disappearance of the abdominal symptoms. This observation confirms the possible association of migraine with a picture simulating an acute abdomen and suggests that the differential diagnosis with a true surgical condition may be achieved by the observation of the progression of symptoms and by early evaluation of patient with EEG.

A multicentre, retrospective study of hereditary deficiency of C1-esterase inhibitor (C1-INH) function, a deficiency which clinically manifests as hereditary angioedema (HAE), was performed in six centres in Germany, Austria and Switzerland. 242 individuals were registered with proven functional or quantitative deficiency of C1-INH who belonged to kindered with disease manifestation in 2 to 6 generations. Considering the total population in the three countries and the number of registered individuals, a frequency of the deficiency of 0.02 x 10(-4) was calculated. As this epidemiological study involved only 6 centres, a 10 to 100 times higher frequency of C1-INH deficiency is estimated to be a more realistic value. Out of the 242 registered individuals 110 were evaluated for type and location of clinical manifestation of the deficiency, the laboratory data and the therapy outcome. 86 (78.2%) of the patients belonged to the "common type" and 24 (21.8%) to the "variant type" of HAE. In 53.9% of the cases first manifestation of the disease was before the age of 20 years. In only 3.9% of the patient population did the disease begin after 40 years of age. A mean time lag of 5,3 years was observed, between the first manifestation and correct diagnosis. Initial diagnosis was correct in only 31.8% of the cases of which dermatologists provided 51.7%. False diagnoses include urticaria (41.3%), allergy (20%), acute abdomen (18.7%), angina (8%), rheumatoid disease (5.3%) and intracranial haemorrhage, CNS tumour, epilepsy, migraine (5.3%). The distribution pattern of HAE resembled that of intolerance reactions and pseudoallergies. Urticarial lesions were not associated with C1-INH deficiency. 24% of the patients had at least one episode of laryngeal edema. 40% of patients were unable to identify a trigger of edema formation. The others indicated as triggers trauma, hormonal changes, mental stress, insect stings and in a few cases food and drugs. Menstruation and oral contraceptives aggravated or made disease manifestations more frequent. In contrast, during pregnancy in many cases clinical manifestations improved and delivery posed no problems. The possibility of HAO is very much suggested by the tailure of edema to respond to classical anti-allergic therapy. Therapy of choice of acute attacks is C1-INH concentrate. No side reactions, antibody formation or virus transmission have been observed. For long term prophylaxis danazol, an attenuated androgen, or tranexamic acid, a protease inhibitor, was chosen. The daily dose of danazol should be kept as low as possible because of its anabolic, anti-estrogenic, anti-gestagenic, and anti-gonadotropic effects. Indeed, adverse reactions were observed in 41.7% of patients receiving danazol. Frequencies of adverse reactions were twice as common in women as in men. Adverse reactions were dose dependent and reversible except for one woman with irreversible deepening of her voice. Measuring C1r is a effective way to assess C1-INH function and monitor therapy.
