Modern lasers allow different parameters to be altered in an effort to gain further improvement in otherwise resistant capillary vascular malformations (CMs). The aim of this study was to examine the effect of changing the pulse duration, wavelength, spot size, and fluence on the color and capillary architecture of 585-nm pulsed-dye, laser-resistant CMs. Eighteen patients were assessed with a depth measurement videomicroscope (DMV) before and after 12 test patches with ScleroPlus and V-Beam lasers at specified parameters. In the majority of the test patch areas, there was little improvement after treatment. However, 44% of patients had greater than 75% clearance in at least 1 test patch site. This study demonstrates that both lasers can achieve further lightening in 585 nm 0.45 msec pulsed-dye laser-resistant CMs. However, in CMs consisting of small-diameter deep vessels, further improvement is unlikely.

Introduction: Congenital heart disease (CHD)-associated malnutrition is a systemic consequence of CHD. Dietary recommendations to fulfill nutritional requirements are lacking. This randomized controlled trial (RCT) was conducted to determine the efficacy of early enteral feeding with supplemented expressed breast milk (suppl-EBM) versus expressed breast milk (EBM) in improving the weight of postoperative cardiac surgical infants.

Immunonutrition, which involves the targeted use of specific nutrients to enhance immune function and mitigate inflammation, has recently become a mainstay for both medical and surgical benefits. This review explores the evolution, mechanisms, and clinical applications of immunonutrition, with a focus on essential nutrients, such as omega-3 fatty acids, glutamine, arginine, and vitamins. These immunonutrients modulate immune responses, reduce pro-inflammatory cytokines, and support tissue repair.

More than 1 million permanent pacemakers are implanted worldwide each year, half of which are in patients with high-grade atrioventricular block. Pacemakers provide adequate frequency support in the initial stage, but traditional right ventricular (RV) pacing may lead to or aggravate left ventricular dysfunction and arrhythmia. Several potential risk factors for heart failure and arrhythmias after pacemaker surgery have been identified, but their occurrence remains difficult to predict clinically.

Background: Nonthermal, pulsed shortwave (radiofrequency) therapy (PSWT) is a nonpharmacologic, noninvasive modality that limited evidence suggests provides analgesia. Its potential favorable risk-benefit ratio stems from its lack of side effects and significant medical risks, applicability to any anatomic location, long treatment duration, and ease of application by simply affixing it with tape. Even with a relatively small treatment effect, PSWT might contribute to a multimodal analgesic regimen, similar to acetaminophen.
