Erosive pustular dermatosis of the scalp (EPDS) is an uncommon chronic inflammatory response to scalp trauma that usually resolves with cicatricial alopecia. It most commonly affects elderly patients with a history of actinic damage. Herein, we describe a 16‐year‐old girl with acrofacial dysostosis type 1 presenting after surgery with crusting purulent scalp lesions, whose clinical presentation and histopathologic findings were consistent with EPDS. A review of the literature on EPDS in children is also detailed.  相似文献

目的分析我院2014-2018年剖宫产率及剖宫产指征的变化,探讨降低剖宫产率的策略和措施。方法回顾性分析2014年1月至2018年12月于我院行剖宫产分娩的42385例产妇的临床资料,分析其剖宫产率及主要剖宫产指征。结果2016年的剖宫产率均低于2014年、2015年、2017年、2018年,差异具有统计学意义(P<0.05)。瘢痕子宫在二胎政策开放后所占比例明显增加;羊水过少及相对头盆不称所占比例呈现逐年下降的趋势。2014-2018年,母体因素所占比例均最高,胎儿因素及头盆因素所占比例逐年下降。另外,社会因素在二胎生育政策开放后仍呈上升趋势。结论2016年剖宫产率明显下降,瘢痕子宫在二胎政策开放后所占比例明显增加。临床需提高剖宫产术后再次妊娠阴道试产的比例、提高助产技术水平、发挥营养门诊及助产士门诊的作用、提高产科医生对胎心监护的正确解读以降低剖宫产率。  相似文献

Rationale:Mucous membrane pemphigoid (MMP) is a rare, autoimmune bullous disease that affects mucosal surfaces and skin. Early and aggressive treatment initiation may be warranted due to the risks of serious complications. However, it can be challenging to make an initial diagnosis. Viral infection such as hepatitis B virus (HBV) infection has been found to be associated with the formation of autoimmune bullous diseases.Patient concerns:The patient was a 43-year-old male with gingivitis and recurrent swelling over the neck, cheeks, lips, and eyelids. The patient presented at oral medicine, otolaryngology, plastic surgery, and ophthalmology sequentially, and was later referred to the rheumatology, dermatology, and family medicine departments. Recurrent hemorrhagic bullae on oral mucosa and skin scarring occurred 2 years after the onset of the initial symptoms.Diagnosis:Skin biopsy with direct immunofluorescence was performed under the suspicion of MMP. Lesional hematoxylin and eosin stain and perilesional direct immunofluorescence were consistent with MMP.Interventions:Systemic Prednisolone and topical corticosteroid were used to control the disease.Outcomes:A flare-up of hepatitis B developed as a result of systemic prednisolone use. The disease went through relapses and remissions. The patient is on low-dose prednisolone (5 mg/day) with a monthly outpatient visit in the family medicine department.Lessons:It would be useful for medical practitioners in different specialties to be alert of the heterogeneous presentations of MMP. Chronic HBV infection might be a risk factor for MMP. In patients with chronic HBV infection, treatment of MMP must be closely monitored for the risk of reactivation of HBV.  相似文献

目的:比较显微镜下Hotz法联合睑缘切开皮瓣转位术和单纯Hotz法治疗重度上睑瘢痕性睑内翻的临床效果。

方法:回顾性分析2017-07/2019-07在我院接受上睑内翻倒睫矫正术的患者60例84眼,试验组32例42眼采用显微镜下Hotz法联合睑缘切开皮瓣转位术,对照组28例42眼采用单纯Hotz法。术后随访观察至12mo, 记录患者主观症状、睑缘位置、睫毛外翻情况及满意度。

结果:试验组单眼平均手术时间长于对照组(40.8±2.57min vs 28.5±2.64min,P<0.01)。术后1、12mo,试验组治愈率分别为100%、95%,对照组治愈率分别为95%、76%,术后12mo试验组治愈率优于对照组(P=0.013)。 术后1mo两组患者满意度无差异(Z=1.1825,P=0.2371),术后12mo试验组患者满意度高于对照组(Z=3.7346,P<0.01)。

结论:对于重度上睑瘢痕性睑内翻,显微镜下Hotz法联合睑缘切开皮瓣转位术虽手术时间长于单纯Hotz法,但其远期疗效优于单纯Hotz法,术后12mo患者满意度较高。  相似文献

Folliculitis decalvans is a neutrophilic cicatricial alopecia characterised by progressive pustular folliculitis. Folliculitis decalvans is seen as a condition usually limited exclusively to the scalp and rarely affects the limbs. We present a case of a 63-year-old man with a 3-year history of progressive pustular folliculitis with inflammatory patches and central scarring alopecia on both forearms and a circumscribed patch on his right lower leg. His presentation, clinical course and isolation of Staphylococcus aureus together with the histopathological findings all supported a folliculitis decalvans-like pustular folliculitis limited to the limbs. Biopsies revealed follicular pustules, gross interfollicular fibrosis with plasma cells and concentric perifollicular fibrosis with lymphocytes, all features seen with folliculitis decalvans. The positive response to antibiotics combined with topical corticosteroids mirrored the response seen with scalp folliculitis decalvans. In contrast to the previously reported cases, the patient had no evidence of folliculitis decalvans on the scalp.  相似文献

目的探讨瘢痕性睑外翻的手术细节的改进及治疗效果。方法回顾我科收治的Ⅱ、Ⅲ度瘢痕性睑外翻患者46例,根据睑外翻的程度和局部情况,选择眼睑部正常皮肤与瘢痕组织交界处设计切口线,尽可能保留和恢复眼轮匝肌结构,松解区域分别超出内外眦处并达眼裂水平,采用全厚皮片游离移植术行睑外翻手术矫正并行睑缘融合,皮片于内外眦韧带处行皮内固定。结果随访6个月至2年,46例眼睑皮片完全存活,眼睑复位良好,无1例眼睑闭合不全。结论适当的选择手术切口线及松解范围,尽可能保留眼轮匝肌的结构完整并对移植皮片在内外眦处进行固定,可以有效预防睑外翻的复发,提升手术效果。  相似文献

目的:探索专项护理在眉再造同期治疗瘢痕性秃发术中的应用效果。方法:根据手术过程分两期进行专项临床护理。扩张器一期置入术后进行扩张器相关专项护理,严密监测扩张注水情况,密切观察扩张部位,防止扩张皮瓣坏死或感染;眉再造和瘢痕性秃发修复二期术后密切观察再造眉毛头皮条的颜色,避免静脉回流不畅发生。结果:本组12例患者进行了眉再造的全方位密切护理,岛状头皮瓣全部存活,头皮瘢痕全部修复,无一例皮瓣坏死。随访6~24个月,再造眉毛毛发密度与健侧非常接近,眉形自然逼真,手术效果满意。结论:在可调控眉毛密度的眉再造同期治疗瘢痕性秃发术中进行全方位护理是手术成功的重要保障。  相似文献

Skin diseases presenting with keratotic papules, atrophy, cicatricial alopecia and/or “lichenoid” histopathologic changes have been described under at least 30 names. This family of diseases contains 2 subgroups, largely based on clinical features: keratosis pilaris atrophicans (KPA; including keratosis pilaris atrophicans faciei/ulerythema ophryogenes, atrophoderma vermiculatum, and keratosis follicularis spinulosa decalvans); and the lichen planopilaris (LPP) subgroup (including LPP, frontal fibrosing alopecia, Graham‐Little‐Piccardi‐Lassueur Syndrome and fibrosing alopecia in a pattern distribution). An interface dermatitis with lichenoid inflammation is characteristic of the LPP group of disorders, but the literature provides scant information about the histopathology of the KPA group. Our experience has been that the 2 subgroups show a unifying histologic similarity as well as considerable clinical overlap. Because these conditions overlap clinically and histologically, we propose that the term lichenoid folliculitis (LF) be used to refer to this group of diseases, thus simplifying cumbersome nomenclature and highlighting the possibility of shared pathogenesis and treatment options.  相似文献
