BACKGROUND: Low fluence 1,064 nm Q-switched (QS) Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser treatment, also known as laser toning, is widely used for pigmentary disorders. There has been no reliable evaluation of the effect of low fluence 1,064 nm QS Nd:YAG laser for senile lentigo. OBJECTIVE: To investigate the beneficial effect of low fluence 1,064 nm QS Nd:YAG laser in the treatment of senile lentigo on the face. METHODS: A retrospective review was conducted on patients treated only with repetitive low fluence 1,064 nm QS Nd:YAG laser. Among them, 12 patients with multiple senile lentigines before treatment were included. All side effects were recorded to assess the safety of the modality. RESULTS: Mean age was 56.1±7.8 years old and male-to-female ratio was 1:11. Mean treatment fluence was 1.62±0.16 J/cm² and mean total treatment session was 8.8±2.6. Mean interval period between each session was 28.0±11.4 days and mean treatment session to reach marked and near total improvement was 8.7±2.8. At the final visit, seven of 12 (58.3%) patients reached marked and near total improvement, and three of 12 (25.0%) reached moderate improvement. No side effects occurred. CONCLUSION: Repetitive low fluence 1,064 nm QS Nd:YAG laser treatment may be an effective and safe optional modality for senile lentigo.

PURPOSE: Hypothermia at admission is associated with increased mortality and morbidity in preterm infants. We performed a quality improvement (QI) effort to determine the impact of a decrease in admission hypothermia in preterm infants. METHODS: The study enrolled very low birth weight (VLBW) infants born at Gangnam Severance Hospital between January 2013 and December 2016. This multidisciplinary QI effort included the use of occlusive wraps, warm blankets, and caps; the delivery room temperature was maintained above 23.0℃, and a check-list was used for feedback. RESULTS: Among 259 preterm infants, the incidence of hypothermia (defined as body temperature <36.0℃) decreased significantly from 68% to 41%, and the mean body temperature on neonatal intensive care unit admission increased significantly from 35.5℃ to 36.0℃. In subgroup analysis of VLBW infants, admission hypothermia and neonatal outcomes were compared between the pre-QI (n=55) and post-QI groups (n=75). Body temperature on admission increased significantly from 35.4℃ to 35.9℃ and the number of infants with hypothermia decreased significantly from 71% to 45%. There were no cases of neonatal hyperthermia. The incidence of pulmonary hemorrhage was significantly decreased (P=0.017). Interaction analysis showed that birth weight and gestational age were not correlated with hypothermia following implementation of the protocol. CONCLUSION: Our study demonstrated a significant reduction in admission hypothermia following the introduction of a standardized protocol in our QI effort. This resulted in an effective reduction in the incidence of massive pulmonary hemorrhage.

Objectives: This study aimed at investigating the pharmacological and physiological effects of cannabidiol (CBD) oil on weight loss in diet-induced obese (DIO) mice. Methods: A DIO mice model was constructed with 33 C57BL/6 male mice, aged six weeks, who had been fed a high-fat diet for 13 weeks. Subsequently, 20 mg/kg (n=11) or 60 mg/kg (n=11) of CBD oil or sesame seed oil (n=11) per day was given along with a high-fat diet for four weeks. The body weight of each subject was measured weekly, and venous blood was drawn for biochemistry and enzyme-linked immunoassay before and after the four-week trial period. An oral glucose tolerance test was performed to assess glucose metabolism. At the end of the CBD oil treatment, dual-energy X-ray absorptiometry was used to calculate body fat composition, and the mesenteric adipose tissue was measured as representative of the fat mass of each subject. For statistical analysis, we used the Kruskal-Wallis test, Turkey’s test using ranks and generalized estimating equations. Results: After administration of CBD oil (60 mg/kg) for four weeks, the DIO mice showed significant weight loss, compared to the sham control mice (p=0.027). Mice fed with 60 mg/kg of CBD oil also had a significant reduction in fat percentage (p=0.009) and mesenteric fat weight loss (p=0.024), compared to the sham control mice, even with higher food intake (p=0.029). Moreover, mice fed with 60 mg/kg of CBD oil showed a significant improvement in glucose tolerance (p=0.003) and lower plasma leptin levels (p=0.006). Conclusion This study shows that orally administered CBD oil induces weight loss in DIO mice. It has been postulated that CBD oil attenuates an over-activated endocannabinoid system, thereby increasing energy expenditure, and improving glucose metabolism and leptin resistance.

BACKGROUND: There is substantial evidence that the vestibular system is involved in the regulation of blood pressure. Heart rate variability (HRV) is useful to investigate the role of the peripheral vestibular receptors and the baroreceptors in the orthostatic tolerance. METHODS: EKG was recorded during postural changes with the head up either after sinoaortic denervation or after bilateral labyrinthectomies in Sprague-Dawley rats. HRV, including mean, standard deviation, coefficient of variation (CV), and power spectrum, were analyzed from R-R intervals of EKG. RESULTS: Phenylephrine increased low frequency region and sodium nitroprusside increased high frequency region in the power spectral analysis of HRV in anesthetized rats. Postural changes decreased blood pressure transiently and then increased blood pressure gradually in control rats, but the depression of blood pressure induced by postural change was greater in rats with both sinoaortic denervation and bilateral labyrinthectomies. The increase of CV of HRV just after sinoaortic denervation or bilateral labyrinthectomies represents an unstable heart rate in resting position, however, CV of HRV was increased markedly by postural change 7 days after bilateral labyrinthectomies. Postural change with sinoaortic denervation increased low-frequency region representing sympathetic activity, whereas bilateral labyrinthectomies increased highfrequency region representing parasympathetic activity in power spectral analysis. CONCLUSIONS: These results suggest that both the peripheral vestibular receptors and the baroreceptors have subsidiary action in orthostatic tolerance and the peripheral vestibular receptors regulate blood pressure during postural change through the sympathetic nervous system.

Pneumococcus is the most frequently encountered causative pathogen in community-acquired pneumonia in elderly patients. The pneumococcal polysaccharide vaccine (PPV23) is widely used for preventing pneumococcal diseases in adults. PPV23 is relatively safe; however, some cutaneous adverse reactions, including localized mild inflammation associated with erythema, a sensation of heat, and tenderness, have been reported. Systemic reactions such as myalgia, arthralgia, and headache have also been reported, though severe adverse reactions are rare. In the Korean literature, a case of localized toxic reaction near the injection site after pneumococcal conjugate vaccine (PCV13) administration was previously reported. However, there are no published reports of a generalized skin rash after PPV23. Herein, we report a case of PPV23-induced generalized skin rash on the face, neck, upper trunk, and both arms with a local adverse reaction at the injection site after vaccination.
