A new material is proposed in dentistry in the form of strips for producing gingival retraction. The clinical efficacy of the material remains untested. ⋯ Merocel strip produces more gingival displacement than the conventional retraction cord.

Because of potential side effects of chemical treatments and in order to decrease the risk of nausea and vomiting in post-operative patients, there is a necessary requirement for some alternative therapeutic methods such as Acupressure. ⋯ In parturients who underwent caesarean deliveries which were performed under spinal anaesthesia in this study, use of Metoclopramide and Acupressure was found to be equally effective for reducing emetic symptoms (nausea, retching, and vomiting).

Erythema multiforme and related disorders comprise a group of mucocutaneous disorders that often compromise the quality of life. The clinical classification of these disorders is variable, thus making definitive diagnosis difficult. Early recognition and prompt management will benefit the patients. This article highlights two such cases of erythema multiforme with detailed literature review on etiopathogenesis, clinical features, and treatment.

Single acute bouts of moderately-intense aerobic exercise like walking have been found to improve cognitive control of attention in children, but some studies have reported no improvement in cognitive flexibility following acute aerobic exercise. Submaximal aerobic exercise performed for 60 minutes facilitated specific aspects of information processing in adults but extended exercises leading to dehydration compromised both information processing and memory functions. Improvement in executive functions has also been reported during cycling at 70% of Heart Rate Reserve (HRR) across young and older age groups. However, there are studies which have reported no correlation between physical activity and academic performance in children and a recent systematic review of 30 relevant studies reported no significant improvement in cognition with physical activity or exercise in adults. There seems to be lack of consensus on the effect of exercise on cognition, which may be because the exercise protocols used and cognitive functions tested by different researchers were not uniform. ⋯ A single bout of moderate intensity aerobic exercise for as less as 30 minutes can improve some aspects of cognition, most prominently for memory, reasoning and planning and can shorten the time taken to complete the tests.

Cardiac blood flow measurements are useful in the haemodynamic management of neonates. Cardiac blood flows can be estimated with functional echocardiography as follows; flow in Superior Vena Cava (SVC), Right Ventricular Outflow (RVO) and Left Ventricular Outflow (LVO). Studies in preterm infants have shown that abnormal superior vena cava flow is associated with poor neurodevelopmental outcomes. To date, normative data on LVO, RVO and SVC flows has been established for term appropriate for gestational age neonates and preterm neonates, but no data is available on RVO, LVO and SVC flows for term small for gestational age neonates. ⋯ This study provides RVO, LVO and SVC flow values in a cohort of stable term SGA neonates after the transitional period.
