Caffeine for Headaches: Helpful or Harmful? A Brief Review of the Literature.

Consumption of caffeine in the diet, both daily and occasional, has a significant biological effect on the nervous system. Caffeine, through various and not yet fully investigated mechanisms, affects headaches. This is especially noticeable in migraine. In other headaches such as hypnic headache, post-dural puncture headache and spontaneous intracranial hypotension, caffeine is an important therapeutic agent. In turn, abrupt discontinuation of chronically used caffeine can cause caffeine-withdrawal headache. Caffeine can both relieve and trigger headaches.

Variability in melatonin concentration in blood serum of patients with episodic migraine: a pilot study.

AIM OF STUDY: This study was aimed at assessing the possible effect of melatonin concentration on migraine. The serum concentration profile of melatonin in patients with diagnosed episodic migraine in the interictal period was compared to the profile in patients without migraine. Then, a correlation between the frequency and duration of migraine attacks, and the possible relationship between these parameters and melatonin levels in individual patients, was established. CLINICAL RATIONALE FOR STUDY: Melatonin secretion is related to migraine pathophysiology in many different ways. MATERIALS AND METHODS: The study was conducted in a group of 58 subjects (48 women and 10 men). The study group comprised 29 patients (24 women and five men) diagnosed with migraine according to the International Classification of Headache Disorders (ICHD-3 beta), within the framework of the Outpatient Clinic at Bielanski Hospital in Warsaw and the Clinical Department of Neurology of the 2nd Faculty of Medicine (now known as the Faculty of Medical Sciences) at the Medical University of Warsaw, Poland. The control group consisted of 29 subjects (24 women and five men) with no headache. Blood samples for the determination of melatonin were collected at midnight, 2am, 3am, 4am and 6am. Melatonin level in a frozen serum of venous blood was determined by a radio-immuno-enzymatic method at the Department of Histology and Embryology of the Faculty of Veterinary Medicine at the University of Warmia and Mazury in Olsztyn, Poland. RESULTS: No statistically significant differences between the levels of melatonin and the averaged advances of melatonin profiles were observed in the examined and the control group. There were demonstrated medium negative correlations between the maximum value of melatonin and the duration of migraine (R = -0.4, p = 0.03). There were also observed statistically significant differences (p = 0.01) between the averaged advances of melatonin profiles, depending on the duration of migraine. CONCLUSIONS AND CLINICAL IMPLICATIONS: Our study showed no abnormalities of melatonin secretion in patients with migraine during the interictal period. The results of studies available in the literature depend on the nature of the headache (episodic or chronic) and the time of measuring the concentration of melatonin (during a headache attack or in an interictal period).

Short-term effect of kinesiology taping on temperature distribution at the site of application.

The aim of the study was to assess skin temperature after short-term kinesiology tape application. Seventy-four healthy volunteers with no history of lower back pain participated in the study. Kinesiology tape was applied in the experimental group, and Matopat Classic adhesive tape was applied in the placebo group. Study participants wore the tape for four consecutive days and were then thermographically analyzed for changes in skin temperature. Examination of skin surface temperature distribution revealed a significantly lower temperature (mean decrease, 1.3°C P = .001 area1, 1.5°C P = .001 area2, 1.6 P = .008 area3) immediately after kinesiology tape the removal. One hour after removal of the tape, a statistically significant increase in temperature was observed over all three areas (mean increase, 0.9°C P = .025 area1, 1.0°C P = .0008 area2, 1.0 P = .011 area3). In group 2, there were no statistically significant temperature changes. Based on the findings, we determined that kinesiology taping may affect skin temperature at the site of application.

Evaluation of the Effectiveness of Preoperative Physiotherapy Using the Lysholm-Gillquist Scale in Patients Qualified for Surgical Arthroscopic Anterior Cruciate Ligament Reconstruction - Pilot Study.

BACKGROUND: Recent years have seen a noticeable increase in the number of people experiencing total damage to the anterior cruciate ligament in the knee joint. The causes are many, but increased sporting activity among people who generally lead a hypokinetic lifestyle is regarded as the most important factor. Researchers are seeking to optimize the surgical treatment and rehabilitation. AIM OF THE STUDY: To evaluate the effectiveness of preoperative physiotherapy according to the Lysholm and Gillquist scale in patients scheduled for arthroscopic anterior cruciate ligament reconstruction. MATERIAL AND METHODS: The study involved a random sample of 30 patients with confirmed complete rupture of anterior cruciate ligament (ACL) qualified for surgical ACL reconstruction. Within this group, an experimental group consisted of 15 patients (mean age 41.0 ± 7 years) who attended physiotherapy before surgery based on recognized therapeutic models. A control group consisted of 15 patients (mean age 39.0 ± 9 years). The Lysholm and Gillquist 100-point scale was used for assessment. Student's t test, the Mann-Whitney U test and the Wilcoxon test were used for statistical analysis. The level of statistical significance was set at p < 0.05. RESULTS: The operated knee improved functionally in both the experimental and control group. In the experimental group, the difference was 20 points and was statistically significant at p = 0.000. In the control group, the difference was 6 points, which was also within the limit of statistical significance at p = 0.002. CONCLUSIONS: 1. Patients with total ACL rupture attending a pre-operative rehabilitation program led by a physiotherapist (experimental group) achieved greater improvement in functional status compared with the control group. 2. These results indicate a need to analyze the impact ofpreoperative rehabilitation on the final outcome of patients after complete ACL rupture.
