elastosis perforans serpiginosa glans penis Wilson disease a b s t r a c t Elastosis perforans serpiginosa (EPS) is an unusual perforating disorder characterized by extrusion of altered elastic fibers through the epidermis. Clinically, it presents as keratotic papules with a tendency for serpiginous or annular distribution that most commonly involves the sides of the neck and the back. However, involvement of the penis has rarely been reported. We present a case of EPS involving the neck,

Skin biopsy revealed perforating channels containing numerous altered elastic fibers, with a characteristic "bramble brush" or "lumpy-bumpy" appearance as demonstrated by an elastin stain. The latter is thought to be pathognomonic for penicillamine-induced degenerative elastosis. These degenerative changes occurring in glans penis have rarely been described in the literature. Prompt recognition of the rare presentation could lead to early discontinuation of the offending drug, to prevent further sequelae.

Human mycobiome and diseases

Xin Shen, Yu-Fei Yao, Ji-Yao Li, Yan Li
2019 Hua xi kou qiang yi xue za zhi = Huaxi kouqiang yixue zazhi = West China journal of stomatology  
The proportion of mycobiome is less than 1% of human microbiome. However, fungal community plays a key role in human health and diseases. With high-throughput sequencing applications, the structure and composition of mycobiome in the mouth, lung, gut, vagina, and skin have been analyzed, and the role of microbiome in diseases has been investigated. Mycobiome also influences the composition of bacteriome and includes key species that maintain the structure and function of microbial communities.

A review of peri-implant microbiology

Lei Cheng, Hai-Yang Yu, Yao Wu, Chong-Yun Bao, Bang-Cheng Yang, Yi Man, Yao Sun, Xiao-Li Yan, Xue-Dong Zhou
2019 Hua xi kou qiang yi xue za zhi = Huaxi kouqiang yixue zazhi = West China journal of stomatology  
Dental implants represent the majority of treatment strategies used to replace missing teeth. However, peri-implant diseases caused by disturbance in peri-implant microbiological balance are among the reasons for implant failure. Since the 1980s, peri-implant microorganisms have been a hot research topic in dental microbiology. The bacterial ecology between the disease and health largely differs, which directly or indirectly increases the risk of peri-implant diseases. Accordingly, the

Background/Objective: Microwave-based devices target sweat glands through energy delivery at the dermalesubcutaneous interface. These devices have been approved by the Food and Drug Administration as a noninvasive treatment for axillary hyperhidrosis. Treatment for osmidrosis has only been reported in one preliminary study. This study aimed to investigate the efficacy, safety, and histological changes of the microwave-based devices in treating axillary osmidrosis. Methods: We conducted a

Skin biopsy was obtained to evaluate histological changes. The efficacy was determined by odor reduction using a patient reported 10-point odor scale. Responders were defined as participants with a reduction of at least 3 points of the Odor-10 score at their 90-day follow-up visit. Results: Seven patients were enrolled. Mean reduction of odor was 61.8%. Six patients met the primary endpoint of odor reduction. Skin biopsy specimens reveled 93% reduction of apocrine glands. Histopathological changes include dermal fibrosis, necrosis of sweat glands, and subcutaneous fat necrosis. Transient swelling, bruise, numbness, lumps, and hypotrichosis were possible side effects. No patient reported disabling side effects. Conclusion: Microwave-based devices are noninvasive and a potential alternative therapeutic modality for axillary osmidrosis treatment.

2019 Hua xi kou qiang yi xue za zhi = Huaxi kouqiang yixue zazhi = West China journal of stomatology  
目的 初步探讨正畸应力加载后牙龈肌成纤维细胞的表达情况。方法 选取8例正畸应力加载后需要拔除牙牙龈组织,以应力加载前拔除牙牙龈组织为对照,进行α-平滑肌肌动蛋白(α-SMA)、Ⅰ型胶原、Ⅲ型胶原免疫组织化学染色。然后进行测量和统计分析。结果 正畸应力加载前牙龈组织内Ⅰ型胶原、Ⅲ型胶原免疫组化染色阳性,α-SMA除血管上皮外,其余为阴性表达。正畸应力加载后,Ⅰ型胶原、Ⅲ型胶原表达明显上升,差异有统计学意义(P<0.05);α-SMA在牙龈组织内出现阳性表达,与加力前差异有统计学意义(P<0.05)。结论 正畸应力加载后,牙龈组织内肌成纤维细胞出现表达,其可能在正畸牙术后复发中发挥一定作用。.
