Abdominal Decompression

Introduction: Maternal abdominal decompression during pregnancy could be used in an attempt to improve utero-placental blood flow. We utilized Doppler ultrasonography to investigate the effects of this procedure on blood flow in the umbilical artery and fetal middle cerebral artery. Methods: Women (n = 23) with singleton pregnancies attending antenatal abdominal decompression were enrolled in the study. Doppler velocity waveforms were obtained from umbilical artery and fetal middle cerebral artery before and after a 30-minute decompression session. Resistance indices were compared using the Student's t - test (p < 0.05 significant). Results: 23 healthy pregnant women were included at an average gestational age of 36+1 weeks. The mean resistance index before decompression in the umbilical artery was 0.58 (s = 0.10) and after decompression 0.54 (s = 0.07, p = 0.06). In the middle cerebral artery the values were 0.72 (s = 0.11) and 0.77 (s = 0.08), respectively (p = 0.01). Discussion and conclusion: Significantly increased resistance index in the middle cerebral artery implies a higher fetal brain oxygenation after decompression. This is further corroborated by the trend towards a decrease in umbilical artery resistance index. The effects of decompression could be beneficial in pregnancies complicated by IUGR or hypertensive disorders of pregnancy.

Vascular Beds

Unlike many peripheral vascular beds, the sympathetic nervous system exerts little control on cerebral blood flow. The contractile response of isolated rabbit middle cerebral artery (MCA) segments to electrical field stimulation of its intramural nerves is less than in a similar-sized artery from the ear. This study was undertaken to characterize and compare the perivascular neuromuscular relationships and innervation density of similar-sized arteries varying in diameter from these two different regional arterial beds to see if there were structural correlates for these functional differences.

Type Headache

Introduction. According to the defi nition of the World Health Organization (WHO), tension-type headache (TTH) is the most common type of primary headache. Rehabilitation of patients with chronic tension-type headache continues to be an important socio-medical problem. Its main goal is the most complete restoration of the functions of the musculoskeletal system of the neck, the correction of vascular and psychoemotional problems, and the patient′s return to his everyday life and work. As a rule, the main emphasis in the treatment of such patients is placed primarily on drug therapy. At the same time, practitioners are faced with a number of problems — the low effectiveness of the treatment, the nonpersistency of the results, allergic reactions, polypharmacy and others. All this suggests that there is a need for differentiated rehabilitation treatment of patients with tension-type headache with the use of various non-pharaceutical methods. The goal of research — to evaluate the clinical effi cacy of complex non-drug therapy in patients with tension-type headache.Materials and methods. The prospective controlled randomized study, which was conducted from October 2017 to March 2019 at the Department of Medical Rehabilitation of the Bashkir State Medical University, included 110 patients with TTH from the age of 20 to 45 years. All patients, depending on the treatment methodology used, were randomly divided into two groups of 55 people. Patients of the main group received complex rehabilitation treatment with the use of non-drug methods: osteopathic correction, acupuncture and exercise therapy. Patients in the control group received treatment in accordance with the standard of medical care for TTH (analgesics, non-steroidal antiinfl ammatory drugs, antidepressants, vasoactive and nootropic drugs). The study of the clinical effectiveness of the therapy included: an assessment of the severity of pain with the use of a visual analogue scale and a tensoalgimeter, a goniometric study with an assessment of the volume of active movements in the cervical spine, transcranial ultrasound dopplerography with an assessment of quantitative indicators in the system of the middle cerebral artery.Results. The use of complex non-drug therapy in patients with TTH compared with standard drug therapy leads to a signifi cantly more important decrease in the severity of pain, an increase in pain threshold, an increase in the volume of active movements in the cervical spine. The effect of non-drug treatment methods on blood fl ow in the system of the middle cerebral artery is comparable in its effectiveness with the use of pharmaceutical drugs.Conclusion. The proposed complex rehabilitation treatment of patients with TTH with the use of non-drug methods has shown clinical effi cacy which is comparable, and in a number of indicators, superior to the effectiveness of conventional medical treatment. All this determines the necessity of wider implementation of multidisciplinary non-drug treatment of patients with this pathology.
