RESUMO
We conducted an observational study of 4926 university students from all over Italy and different university courses, including health areas. Students were contacted through the most popular social networks and some student's course representatives also acted as intermediaries, from June 1 to August 31, 2021. A questionnaire has been carried out using "Google Forms" and MIDAS. The study confirmed how the headache was widespreaded among the student population and how much it was underestimated (only one-fifth of the interviewees had been to a specialist/headache center). The negative impact of habitual headache on school performance was confirmed by the attendance on courses and the overall study performance. The clinical phenomenon might have been impacted by the pandemic period and its changes in lifestyle, in the study methodology, and due to the stress increase. Finally, the means used in the study were very satisfactory: the use of peers of the interviewees and the social networks, obtaining a broad acceptance of the study and possibly offering a method which is likely to be used in the future. Students presenting habitual headaches must be aware of their condition and the need to search for an appropriate diagnosis and treatment.

Objective Episodic cluster headache is characterized by abnormalities in tyrosine metabolism (i.e. elevated levels of dopamine, tyramine, octopamine and synephrine and low levels of noradrenalin in plasma and platelets.) It is unknown, however, if such biochemical anomalies are present and/or constitute a predisposing factor in chronic cluster headache. To test this hypothesis, we measured the levels of dopamine and noradrenaline together with those of elusive amines, such as tyramine, octopamine and synephrine, in plasma of chronic cluster patients and control individuals. Methods Plasma levels of dopamine, noradrenaline and trace amines, including tyramine, octopamine and synephrine, were measured in a group of 23 chronic cluster headache patients (10 chronic cluster ab initio and 13 transformed from episodic cluster), and 16 control participants. Results The plasma levels of dopamine, noradrenaline and tyramine were several times higher in chronic cluster headache patients compared with controls. The levels of octopamine and synephrine were significantly lower in plasma of these patients with respect to control individuals. Conclusions These results suggest that anomalies in tyrosine metabolism play a role in the pathogenesis of chronic cluster headache and constitute a predisposing factor for the transformation of the episodic into a chronic form of this primary headache.

An association between obesity and migraine has been observed in recent studies and it is supported by plausible biological mechanisms. The objective of this study is to evaluate the efficacy of frovatriptan and other triptans in the acute treatment of migraine, in patients enrolled in three randomized, double-blind, crossover, Italian studies and classified according to body mass index (BMI) levels, as normal weight or non-obese (NO, BMI 18.5-24.9 kg/m(2)) and overweight or obese subjects (O, BMI ≥ 25 kg/m(2)). 414 migraineurs with or without aura were randomized to frovatriptan 2.5 mg or rizatriptan 10 mg (study 1), frovatriptan 2.5 mg or zolmitriptan 2.5 mg (study 2), frovatriptan 2.5 mg or almotriptan 12.5 mg (study 3). After treating up to three episodes of migraine in 3 months with the first treatment, patients switched to the alternate treatment for the next 3 months. The present analysis assessed triptan efficacy in 220 N and in 109 O subjects of the 346 individuals of the intention-to-treat population. The proportion of pain free at 2 h did not significantly differ between frovatriptan and the comparators in either NO (30 vs. 34 %) or O (24 vs. 27 %). However, the rate of pain free at 2 h was significantly (p < 0.05) larger in NO than in O, irrespective of the type of triptan. Pain relief at 2 h was also similar between drug treatments for either subgroup. Pain relapse occurred at 48 h in significantly (p < 0.05) fewer episodes treated with frovatriptan in both NO (26 vs. 36 %) and O (27 vs. 49 %). The rate of 48-h relapse was similar in NO and O with frovatriptan, while it was significantly (p < 0.05) higher in O with the comparators. Frovatriptan, in contrast to other triptans, retains a sustained antimigraine effect in NO and even more so in O subjects.

The primary aim of this study (TA-CH, Tryptophan Amine in Chronic Headache) was to investigate a possible role of tryptophan (TRP) metabolism in chronic migraine (CM) and chronic tension-type headache (CTTH). It is not known if TRP metabolism plays any role in CM and/or CTTH. Plasma levels of serotonin (5-HT), 5-hydroxyindolacetic acid (5-HIAA), metabolite of 5-HT, and tryptamine (TRY) were tested in 73 patients with CM, 15 patients with CTTH and 37 control subjects. Of these, plasmatic TRY was significantly lower in CM (p < 0.001) and in CTTH (p < 0.002) patients with respect to control subjects, while 5-HIAA levels in plasma were within the same range in all groups. 5-HT was undetectable in the plasma of almost all subjects. Our results support the hypothesis that TRP metabolism is altered in CM and CTTH patients, leading to a reduction in plasma TRY. As TRY modulates the function of pain matrix serotonergic system, this may affect modulation of incoming nociceptive inputs from the trigeminal endings and posterior horns of the spinal cord. We suggest that these biochemical abnormalities play a role in the chronicity of CM and CTTH.

Postoperative delirium is one of the most spectacular, frightening and misdiagnosed postoperative complications of surgery. We describe the case of a caucasian 77-year-old male patient, who developed a severe postoperative delirium after combined transurethral resection of the prostate and cystolithotripsy. This systemic and unpredictable complication of endoscopic surgery is caused by excessive absorption of electrolyte-free irrigation fluids, leading to brain edema and metabolic encephalopathy. The clinical spectrum ranges from asymptomatic hyponatraemia, to electrocardiographic (ECG) changes, nausea, vomiting, convulsions, coma, pulmonary edema, cardiovascular compromise and death. Because of the heterogeneous clinical presentation diagnosis can be difficult. In a patient who develops alterations of consciousness with evidence of hypervolemia and hyponatremia after endoscopic surgery, transurethral resection syndrome must be considered.

Headache syndromes often involve occipital and neck symptoms suggesting a functional connectivity between nociceptive trigeminal and cervical afferents. Several studies have suggested that pain relief in migraine and other types of headache can be achieved by local injections of steroids, local anaesthetics or a mixture of both in the area of greater occipital nerve (GON). Usually greater occipital nerve block (GONB) is performed by using local anaesthetics alone or with steroid. The rationale of performing a GONB for the treatment of chronic headache states is on the anatomical connections between trigeminal and upper cervical sensory fibres at the level of the trigeminal nucleus caudalis. However, the reason for the improvement after GONB in primary headache is unknown. The objective of this study is to determine whether adding triamcinolone to local anaesthetics increased the efficacy of GONB and trigger point injections (TPIs) for chronic migraine (TM). Patients with TM were randomized to receive GONB and TPIs using lidocaine 2% and bupivacaine 0.5% + either saline or triamcinolone 40 mg. Particularly, a 10-ml syringe containing 4.5 ml of lidocaine 2%, 4.5 ml of bupivacaine 0.5% and 1 ml of either saline (group A) or triamcinolone 40 mg/ml (group B) was prepared for each patients. Patients were given bilateral GONB and TPIs in the cervical paraspinal and trapezius muscles bilaterally. 2 ml were injected into each GON at the medial third of the distance between the occipital protuberance and the mastoid process. In addition, 0.5 ml was injected into each of the 12 trigger points. The total injected volume was 10 ml. The primary outcome measure was the change in mean headache severity from before injection to 20 min after in the two groups. Secondary outcome measures were the change in mean neck pain, photophobia and phonofobia severity from before injection to 20 min after in the two groups. Patients documented headache and severity of associated symptoms for 4 weeks after injection. Changes in symptom severity were compared between the two groups. Thirty-seven patients were included. Twenty minutes after injection, mean headache severity decreased by 3.2 points in group A (p < 0.01) and by 3.1 points in group B (p < 0.01). Mean neck pain severity decreased by 1.5 points in group A (p < 0.01) and by 1.7 points in group B (p < 0.01). Mean duration of being headache-free was 2.7 +/- 3.8 days in group A and 1.0 +/- 1.1 days in group B (p = 0.67). None of the outcome measures differed significantly between the two groups. Both treatments were full tolerated. In our study, adding triamcinolone to local anaesthetic when performing GONB and TPIs was not associated with improved outcome in the sample of patients with TM. In both groups, the procedure resulted in significant and rapid relief of headache, neck pain, photophobia and phonofobia.

In a multicentric, open, preliminary trial, we evaluated the use of ginkgolide B, a herbal constituent extract from Ginkgo biloba tree leaves, in the prophylactic treatment of migraine with aura (MA). Fifty women suffering from migraine with typical aura, or migraine aura without headache, diagnosed according to International Headache Society criteria, entered a six-month study. They underwent a two month run-in period free of prophylactic drugs, followed by a four month treatment period (subdivided into two bimesters, TI and TII) with a combination of 60 mg ginkgo biloba terpenes phytosome, 11 mg coenzyme Q 10, and 8.7 mg vitamin B2 (Migrasoll), administered twice daily. A detailed diary reporting neurological symptoms, duration, and frequency of MA was compiled by patients throughout the trial. The number of MA significantly decreased during treatment (from 3.7 +/- 2.2 in the run-in period, to 2.0 +/- 1.9 during TI and to 1.2 +/- 1.6 during TII; Anova for repeated measures: P < 0.0001). There was also a statistically significant decrease in the average MA duration, which was 40.4 +/- 19.4 min during run-in, 28.2 +/- 19.9 during TI, and 17.6 +/- 20.6 during TII. Total disappearance of MA was observed in 11.1% patients during TI and in 42.2% of patients during T2. No serious adverse event was provoked by Migrasoll administration. Ginkgolide B is effective in reducing MA frequency and duration. The effect is clearly evident in the first bimester of treatment and is further enhanced during the second.
