Randomized Controlled Trial
Does smoking affect the onset time of sensory blocks or the duration of motor blocks in parturient women? A randomized controlled trial.
In general, smoking or exposure to secondhand smoke is still common worldwide, and the rate of smoking in women of childbearing age is gradually increasing. Cesarean section rates have been increasing in recent years, and anesthesia guidelines recommend regional anesthesia for cesarean sections. Since nicotine and local anesthetics have different effects on ligand-gated ion channels, smoking may affect spinal anesthesia in pregnant women. Aim: The aim of this study was to investigate the effects of smoking on spinal anesthesia, which is applied for cesarean sections in pregnant women. Patients and. ⋯ In conclusion, the pregnant women who smoked had longer motor block onset times, shorter motor block durations, higher VAS scores, and lower patient satisfaction levels.

The relationship between blood pressure (BP) trajectories and outcomes in patients with peripartum cardiomyopathy (PPCM) is not clear. Aim: The study aimed to assess the clinical features and outcomes (all-cause mortality and unrecovered left ventricular [LV] systolic function) of PPCM patients grouped according to their baseline systolic BP (SBP). ⋯ In our cohort of PPCM patients, one-fifth was hypotensive at presentation. SBP <90 mmHg at presentation was associated with a four-fold higher risk of all-cause mortality during a median follow-up of 18 months.

Four premolars extractions are routine procedures for correction of malocclusion, but will inevitably lead to a reduction of tongue space, whether this will weaken the pharyngeal airway remains a controversy. ⋯ Four premolar extraction orthodontic treatments did not affect the pharyngeal airway volume except for the vertical liner and cross-sectional area dimensions. The trend of the gold standard suggested a positive influence of four premolar extraction orthodontic treatments.

The effects of commonly used antimicrobial and anticariogenic agents on the adhesion of pit and fissure sealants were investigated in this study. ⋯ Er, Cr: YSGG laser and CPP-ACP containing paste are alternative methods for pre-application of fissure sealants.

The management of pleural effusion usually involves the drainage of the effusion, identification, and treatment of the underlying cause (s). Studies have shown that the initial diagnostic techniques do not give conclusive diagnosis in some cases of pleural effusion. This group of patients described as patients with indeterminate or undiagnosed pleural effusion constitutes a significant proportion of patients with pleural effusion in clinical practice. In this study, we examined the role of video-assisted thoracoscopy (VAT) in the diagnostic work-up of these patients. ⋯ Our results show that video-assisted thoracoscopy plays a useful role in our center in obtaining diagnosis in patients with indeterminate pleural effusion.
