RESUMEN
BACKGROUND: There is no consensus on the role of surgery in the treatment of chronic rhinitis (CR). Should it be considered when nasal symptoms are not controlled by medical treatment? Various targets (turbinates and secretory nerves) and techniques (surgical, laser, cryotherapy, radiofrequency and phototherapy) have been reported, but benefit varies between reports. The aim of this systematic review and meta-analysis was to evaluate results of surgical and instrumental procedures in CR care. METHODS: Two systematic reviews of the US National Library of Medicine, Cochrane Library, Web of Science and Embase databases were conducted in October 15, 2021 (registration numbers CRD42021284257 and CRD42021295227). A database watch was performed until submission of the manuscript. The review focuses on total nasal symptom score (TNSS) and quality of life (QoL) after treatment. All controlled studies reporting nasal surgery/instrumental procedures in adult patients with CR were included. RESULTS: The database search yielded a total of 5628 articles; after eligibility screening, 2091 patients were included from 21 studies. QoL results favored surgery/instrumental procedures over medical treatment (SMD -1.27; 95% CI [-2.38; -0.16]; I2=97%), as did TNSS (SMD -1.40; 95% CI [-2.30; -0.50]; I2=98%). The small number of studies and their heterogeneity did not allow meta-regression to be performed. CONCLUSION: This systematic review supports the use of surgical/instrumental procedures to improve nasal symptom score and QoL of adult patients with CR poorly controlled by medical treatment.

The serotonin syndrome is a potentially deadly complication resulting from drug adverse effect, drug-drug interaction or overdose involving one or more serotonergic molecules, e.g., antidepressants, psychostimulants and sometimes an "ignored" serotonergic compound. The serotonin syndrome typically consists of a clinical triad including cognitive/behavioral, neurovegetative and neuromuscular features. However, this syndrome is characterized by major clinical heterogeneity, making the diagnosis difficult in practice. Moreover, many practitioners are quite unaware of this syndrome. Available scores and classifications can help physicians in their diagnosis approach. Knowing the responsible molecules, their potential interactions and mechanisms of action can help preventing this complication allowing therapeutic education among patients. This updated article reviews the clinical presentation, prevention, management, and pathophysiology of the serotonin syndrome, and addresses the most recent advances in pharmacogenetics regarding this syndrome.

The authors report their experience with dual-chamber pacing in hypertrophy obstructive cardiomyopathy. 22 patients (14 women and 8 men) mean age 60 +/- 13 years were implanted between 1992 and 1998. The criteria for pace-maker implantation were the presence of severe symptoms related with hypertrophy obstructive cardiomyopathy (dyspnea, angina, syncope) and left ventricular outflow tract gradient at mean 30 mmHg. Before pacing, all patients received a medical therapy which included beta-blockers or calcium inhibitors. This treatment was considered as ineffective or responsible of side effects. Patients were followed-up at mean 35.1 +/- 20.3 months. During this period, symptoms improved (mean NYHA class 2.7 +/- 0.5 before pacing vs 1.4 +/- 0.5 after pacing) and left ventricular outflow tract lowered from 95.4 +/- 40.8 to 39.3 +/- 20.5 at 6 months. 34.3 +/- 23.4 at one year and 26.5 +/- 21 at the end of follow-up. Seven patients had RF ablation of atrio-ventricular junction for paroxysmal atrial fibrillation or for lack of hemodynamic improvement with pacing. This procedure permits a significative lowering of gradient and a better ventricular filling. In conclusion, dual-chamber pacing is effective for treatment of hypertrophy obstructive cardiomyopathy when medical therapy is ineffective or bad tolerated at condition of: perfect pacing with permanent ventricular capture and optimal AV delay; RF ablation of AV junction in one third of cases; medical therapy systematically associated in all patients.
