Introduction: Dizziness is a common symptom at the outpatient clinic of family doctors. Its origin is usually multifactorial and its outcome is often benign. However, exists a tendency to relate the dizziness with a cerebrovascular disturbance. AIM. To determine if there are cerebrovascular disorders in patients with chronic dizziness using a non invasive technique.
Patients And Methods: A prospective study was conducted. It included 404 patients without limit of age. The patients were evaluated in a Neurology Outpatient Clinic, to select those patients with chronic instability. A neurosonographic exam was performed to all those selected patients. This exam included colour duplex of the cervical arteries and transcranial Doppler.
Results: Up to 54 % of the patients who were included in the study had a normal carotid study. For the rest of the patients, the thickness intima-media was the most prevalent finding. At the vertebrobasilar system the study of the vertebral arteries was completely normal in 81.7% followed by the presence of microangiopathy in 12.1%. The basilar system was also normal in a high figure (78%) followed by the microangiopathy (17.1%).
Conclusions: The vascular disturbances in the vertebrobasilar system are an exceptional finding in patients with chronic instability.

Thigh Injections of Cabotegravir + Rilpivirine in Virally Suppressed Adults With Human Immunodeficiency Virus Type 1: A Substudy of the Phase 3b ATLAS-2M Study.
Clin Infect Dis

ViiV Healthcare, Durham, North Carolina, USA.
Background: Cabotegravir + rilpivirine (CAB + RPV) administered via intramuscular gluteal injections is the first complete long-acting regimen for maintaining human immunodeficiency virus type 1 (HIV-1) virologic suppression. We present substudy results on short-term repeat intramuscular CAB + RPV long-acting thigh injections in participants with ≥3 years of experience with gluteal administration during the ATLAS-2M study.
Methods: Substudy phases included screening, thigh injection (day 1-week 16), and return to gluteal injection (week 16-week 24).

This article identifies and offers a response to several problems that affect the quality of both clinical education and health care services. These matters are: that in clinical training and practice, health, as lived by patients (persons), is not properly considered, and is equated reductively with treating diseases/disorders; that health is seen through disease, and as restricted to a single model defined by an organism's meeting (or being returned to) biochemical or functional standards; that intellectual assumptions instilled in schools of Medicine and Psychology about realities pertaining to healthcare determine an understanding of chronic illness or life with chronic challenges focused on impairment and suffering, and not on the fuller experience of living with illness, disability or neuropsychological challenges that patients have as persons; that arts-based education reflects the same focus in understanding 'illness', and thus neglects giving attention to the creation of personal health states of those living with challenging or debilitating long-term conditions; that, consequently, the arts are instrumentalized to serve these predefined educational purposes, rather than allowed to inform clinical training through that which is intrinsic or more specific to them. As a way out of these limitations and as an illustration of how things could be done differently, Vincent Van Gogh's paintings of the Sunflowers are used as visual inspiration for how we could change the way we see, and construct new mental representations of 'health', 'chronic illness' or 'chronic challenges', 'patient as person' or even 'person as non-patient', 'the clinician's role' and 'the identity of clinical practice'.

Background: Despite limited breakthroughs in COPD pharmacotherapy, recent trials have shown promising results for biologics in COPD patients. However, robust evidence synthesis in this area is currently lacking.
Methods: We conducted a systematic review of MEDLINE, EMBASE, and Cochrane CENTRAL from inception to July 17, 2024, to identify randomized trials of biologic medications in patients with COPD.
Reimbursement policies of Swiss health insurances for the surgical treatment of symptomatic breast hypertrophy: a retrospective cohort study.

Department of Plastic, Reconstructive and Aesthetic Surgery, Ospedale Regionale di Lugano, Ente Ospedaliero Cantonale (EOC), Lugano, Switzerland.
Background: Patients with symptomatic breast hypertrophy typically suffer from chronic back pain, recurrent skin irritation at the inframammary fold and/or low self-esteem resulting in impaired quality of life. Reduction mammaplasty has been shown to effectively treat symptomatic breast hypertrophy with high patient satisfaction. Despite the obvious benefits, reimbursement requests for reduction mammaplasty are initially often refused by the patient's health insurance company, thereby frequently resulting in additional examinations and eventually extra expenses.
