Treatment of oral manifestations of toxic epidermal necrolysis with low‐level laser therapy in a pediatric patient

Drug‐induced reactions are complications associated with high mortality and significant morbidity. Stevens–Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN) are examples of these conditions, which are characterized by skin and mucous lesions. Here, we report a case of a 9‐year‐old girl who presented with blisters associated with an extensive vesicular rash and multiple ulcerations on the lips and oral cavity. A drug‐induced hypersensitivity reaction to antibiotics was suspected, and a diagnosis of TEN was made. The patient was managed with withdrawal of the suspected causative agent, and the oral lesions were treated with low‐level laser therapy (LLLT) and oral hygiene. This case highlights that TEN requires interdisciplinary intervention with dental assistance and follow‐up to improve symptoms, nutrition, systemic condition, and quality of life.     

健脾温肾软坚解毒方、康艾注射液联合低剂量化疗治疗老年脾肾两虚型晚期非小细胞肺癌的临床研究

目的观察健脾温肾软坚解毒方、康艾注射液联合低剂量化疗对老年脾肾两虚型晚期非小细胞肺癌患者瘤灶、免疫功能及无进展生存期的影响。方法将80例老年脾肾两虚型晚期非小细胞肺癌患者随机分为治疗组和对照组,每组40例。对照组予常规剂量化疗,治疗组予健脾温肾软坚解毒方、康艾注射液联合低剂量化疗。化疗2个周期后,观察两组患者瘤灶、免疫功能的变化情况,随访患者的无进展生存期。结果①试验期间,对照组脱落2例,试验组无脱落,最终完成试验者78例,其中治疗组40例,对照组38例。②两组实体瘤疗效比较,差异无统计学意义(P0.05)。③化疗1个周期与化疗前组内比较,两组血清NK、CD3~+、CD4~+、CD8~+水平差异无统计学意义(P0.05);化疗2个周期与化疗前组内比较,治疗组血清CD8~+水平升高(P0.05),对照组血清NK、CD3~+、CD4~+水平降低(P0.05)。化疗1个周期后组间比较,治疗组血清CD3~+、CD4~+水平高于对照组(P0.05);化疗2个周期后组间比较,治疗组血清NK、CD3~+、CD4~+水平高于对照组(P0.05)。④两组患者中位无进展生存时间均为4.5个月,差异无统计学意义(P0.05)。结论健脾温肾软坚解毒方、康艾注射液联合低剂量化疗能有效控制老年肺肾两虚型晚期非小细胞肺癌患者的瘤灶变化,并有利于稳定血清NK、CD3~+和CD4~+水平,保护患者的免疫功能。     

极低/超低出生体重儿甲状腺功能减退的临床分析

目的 分析极低/超低出生体重（VLBW/ELBW）患儿甲状腺功能减退的危险因素和治疗情况。方法 选择2018年9月至2019年12月诊断为甲状腺功能减退的VLBW/ELBW患儿为病例组（n=29），按照1：3比例匹配甲状腺功能正常的VLBW/ELBW患儿作为对照组（n=87），比较两组患儿的临床特征，分析甲状腺功能与出生胎龄、出生体重的相关性及甲状腺功能减退的危险因素。结果 符合纳入标准的VLBW/ELBW患儿共162例，其中病例组29例，甲状腺功能减退发生率为17.9%。出生体重越低，甲状腺功能减退发生率越高（P < 0.05）；三碘甲状腺原氨酸（T3）、游离三碘甲状腺原氨酸（FT3）与出生胎龄呈正相关（P < 0.05），T3、游离甲状腺素（FT4）与出生体重呈正相关（P < 0.05）。小于胎龄儿、多胎、孕母≥35岁、使用多巴胺是发生甲状腺功能减退的独立危险因素（P < 0.05）。病例组中16例患儿给予左旋甲状腺素（每日5~10 μg/kg）治疗，甲状腺功能在治疗2周后恢复正常。结论 VLBW/ELBW患儿甲状腺功能减退的发生率较高，小于胎龄儿、多胎、孕母高龄、应用多巴胺是其发生甲状腺功能减退的危险因素，应用左旋甲状腺素治疗的患儿需定期随访，以保证用药剂量适宜。     

Effects of box handle position and carrying range on bi-manual carrying capacity for females

This study utilizes a psychophysical approach to examine the effects on carrying capacity for bi-manual carrying tasks involving different handle positions and carrying ranges. A total of 16 female subjects participated in the experiment in groups of two people, and each group of subjects performed the tasks in a random order with 12 different combinations of carrying task. The independent variables are handle position (upper, middle, lower) and carrying range (F–F: floor height carried to floor height, F–W: floor height carried to waist height, W–W: waist height carried to waist height, W–F: waist height carried to floor height), the dependent variable is the maximum acceptable carried weight (MAWC), heart rate (HR), and the rating of perceived exertion (RPE). The results show that the handle position has a significant effect on MAWC and overall RPE but no significant effect on HR. Carrying range has a significant effect on the MAWC and HR, but no significant effect on overall HR. The handle position and carrying range have a significant interaction on the MAWC and HR. The RPE for different body parts shows significant differences, and the hands feel the most tired. Overall, this study confirms that the lower handle position with the W–W carrying range is the best combination for a two-person carrying task.     

Health Implications and Counseling Considerations for Individuals With Piercings and Tattoos

Body art has become common and mainstream. Tattoos and body piercings represent highly individual expressions of identity and personal values. Health care services are enhanced when clinicians understand the anatomy and physiology, common discomforts, and real but rare serious risks of body modification and are prepared to provide compassionate support for individuals’ choices. Special consideration must be given to the needs of childbearing women. By opening channels of communication, clinicians can engage with clients in shared decision making to help those who possess or desire body art take steps to reduce the risk of adverse effects and obtain prompt and effective medical care when problems arise. Through respectful discussion of existing body art, the therapeutic relationship is strengthened, and greater insight into an individual’s health needs may be achieved.
