    肩关节-指甲-泪腺(ADULT)综合征是一种罕见的常染色体显性遗传性疾病,由于TP63基因突变而引起。更常见的是,TP63基因的突变导致外胚层发育不良和/或口面部裂。成人综合征是一种外胚层相关的组织发育不良。这个病例报告描述了一个慢性流泪的病人,先天性闭锁,和泪管阻塞,是成人综合征的主要临床表现。该患者还表现出一些不同于成人综合征的临床表现,即,轻度的眼睑融合和第五指的异常发育(僵硬的第五指,弯曲的长度缩短)。该患者的基因突变也与文献中通常报道的位点不同。在这个病人身上,c.518G>T导致p.G173V(登录号:NM_003722;外显子4)。我们成功地进行了泪囊鼻腔吻合术和人工泪道植入术。如上所示,我们详细讨论了该疾病的临床特征和遗传学。在分享这个案例时,我们旨在有助于目前对ADULT综合征的基因和临床表现的了解,并协助临床医师临床诊断TP63突变相关疾病.
    Acro-dermato-ungual-lacrimal-tooth (ADULT) syndrome is a rare autosomal dominant inherited disease caused due to mutations in the TP63 gene. More commonly, mutations in the TP63 gene result in ectodermal dysplasia and/or orofacial cleft. ADULT syndrome is a type of ectoderm-related tissue dysplasia. This case report describes a patient with chronic tearing, congenital atresia, and obstruction of the lacrimal ducts, which are the main clinical manifestations of ADULT syndrome. This patient also presented with some clinical manifestations that were different from those of ADULT syndrome, namely, mild eyelid fusion and abnormal development of the fifth finger (a stiff fifth finger with camptodactyly that was shortened in length). The gene mutation in this patient was also at a site different from those usually reported in the literature. In this patient, c.518G > T resulted in p. G173V (accession number: NM_003722; exon4). We performed successful dacryocystorhinostomy and artificial lacrimal duct implantation. As shown above, we discussed the clinical characteristics and genetics of the disease in detail. In sharing this case, we aim to contribute to the current understanding of the genes and clinical manifestations of ADULT syndrome and to assist clinicians in the clinical diagnosis of TP63 mutation-related diseases.

    UNASSIGNED:分析先天性鼻泪管阻塞(CNLDO)儿童的微生物学谱和抗生素敏感性模式。
    UNASSIGNED:这项前瞻性比较研究纳入了123例年龄在0-16岁的儿童,诊断为CNLDO,并接受了泪道外科手术。计划进行鼻泪管未闭眼内手术的年龄匹配组的62名儿童被视为对照组。CNLDO组对泪囊进行压力反流后的结膜拭子和对照组的结膜拭子被送去进行微生物学分析。通过KirbyBauer圆盘扩散法对常用抗生素进行了抗生素敏感性测试。
    未经证实:在CNLDO组收集的134个样本中,111(82.8%)样品为培养阳性。分离出165种细菌,其中革兰氏阳性菌139例(84.24%),26例(15.75%的分离株)为革兰氏阴性。在2.23%的病例中获得了真菌分离株。最常见的革兰氏阳性分离株是表皮葡萄球菌(S.表皮)(n=51,占总分离株的30.9%),最常见的革兰氏阴性分离株是流感嗜血杆菌(n=9,占总分离株的5.5%)。革兰阳性菌株对庆大霉素和万古霉素的敏感性最高(各95.5%),革兰氏阴性菌株对阿米卡星(92.3%)。革兰氏阳性和革兰氏阴性分离株均对加替沙星敏感(各80%)。革兰氏阳性的探测结果相似(成功,84.6%)和革兰氏阴性(成功,84.0%)生物。
    未经证实:在CNLDO患儿中,革兰氏阳性分离株占主导地位,表皮葡萄球菌是最常见的。微生物概况对探测结果没有任何影响。
    UNASSIGNED: To analyze the microbiological spectrum and antibiotic sensitivity patterns in children with congenital nasolacrimal duct obstruction (CNLDO).
    UNASSIGNED: One hundred thirty-four eyes of 123 children in the age group of 0-16 years with a diagnosis of CNLDO who underwent lacrimal surgical procedures were included in this prospective comparative study. Sixty-two children in the age-matched group planned for intraocular surgery with patent nasolacrimal duct were deemed controls. The conjunctival swab after performing Regurgitation on Pressure over the Lacrimal Sac in the CNLDO group and the conjunctival swab in controls were sent for microbiological analysis. Antibiotic susceptibility testing was done for commonly employed antibiotics by the Kirby Bauer disk diffusion method.
    UNASSIGNED: Of 134 samples collected in the CNLDO group, 111 (82.8%) samples were culture positive. There were 165 bacteria isolated, among which 139 (84.24% of isolates) were Gram-positive bacteria, and 26 (15.75% of isolates) were Gram-negative. Fungal isolates were obtained in 2.23% of cases. The most common Gram-positive isolate was Staphylococcus epidermidis (S. epidermidis) (n = 51, 30.9% of total isolates), and the most common Gram-negative isolate was Haemophilus influenza species (n = 9, 5.5% of total isolates). Gram-positive isolates were sensitive mostly to gentamicin and vancomycin (95.5% each), and Gram-negative isolates to amikacin (92.3%). Both Gram-positive and Gram-negative isolates were susceptible to gatifloxacin (80% each). Probing outcomes were similar among Gram-positive (success, 84.6%) and Gram-negative (success, 84.0%) organisms.
    UNASSIGNED: There was a predominance of Gram-positive isolates in children with CNLDO with S. epidermidis being the most common. The microbiological profile did not have any effect on the outcomes of probing.

    OBJECTIVE: The aim of reporting this case is to describe a rare combination of blepharophimosis-ptosis-epicanthus inversus syndrome with congenital nasolacrimal duct obstruction. A variety of lacrimal anomalies have been seen in blepharophimosis-ptosis-epicanthus inversus syndrome but the occurrence of nasolacrimal duct obstruction is rare.
    METHODS: The blepharophimosis-ptosis-epicanthus inversus syndrome is an autosomal dominant rare genetic defect with clinical manifestation of dysplasia of the eyelids, palpebral fissures, flat nasal bridge, and ptosis. A 20-month-old boy was referred with the complaints of watering and discharge from his right eyes since birth. On examination, the child had all the features of blepharophimosis-ptosis-epicanthus inversus syndrome with right congenital nasolacrimal duct obstruction in line with the published reports.
    RESULTS: On endoscopic probing and irrigation, the probe could not be visualized into the inferior meatus. On dacryoendoscopy, the membranous part of the nasolacrimal duct was found to be completely obliterated with no light transmission into the nose indicating a malformed nasolacrimal duct. The child was managed by endoscopic dacryocystorhinostomy. We could find only one case report published so far on the combination of congenital nasolacrimal duct obstruction with blepharophimosis-ptosis-epicanthus inversus syndrome. This study adds one more case of blepharophimosis-ptosis-epicanthus inversus syndrome with congenital nasolacrimal duct obstruction and adjuvant use of dacryoendoscopy.

    Congenital nasolacrimal duct obstruction (CNLDO) is the most common cause of epiphora in infancy. Spontaneous resolution occurs in the majority of the cases by 1 year of age. Nevertheless, obstruction has a negative impact on the outcome of conservative or surgical therapy, especially in cases of complex CNLDO. When the condition persists beyond several months, early intervention with dacryoendoscopy (DE) around the age of 1 year could yield good results. The objective of the study is to analyze the success rate and effectiveness of early DE for complex CNLDO in the first year of life.
    A retrospective, non-comparative case series is presented. DE was performed under general anesthesia in patients between the age of 1 and 12 months with severe recurrent acute or chronic dacryocystitis. The medical histories, intraoperative and postoperative results after 3 months as well as via parents\' interviews were analyzed to investigate the success rate.
    A total of 18 consecutive DE in 16 patients between the age of 1 and 12 months (mean 7.3 ± 3.4 months) were studied. Nine lacrimal ducts were diagnosed with persistent chronic dacryocystitis refractory to probing/syringing. The remaining 9 presented recurrent acute dacryocystitis. Diagnostic DE was performed in 18 cases. A therapeutic DE was conducted in 15 lacrimal ducts (83.3%) with simultaneous correction of the associated stenosiswith the tip of the endoscope. A visual controlled opening of the stenosis was impossible in 3 cases due to a too narrow presaccal anatomy (n = 1), an osseous duct stenosis (n = 1), and a bulging membrane of Hasner into the inferior nasal meatus (n = 1). Postoperative findings were classified into four categories: poor, fair, good and excellent. Good results were documented in 16.7% (n = 3) and excellent results in 77.7% (n = 14). The bony obstruction was treated with dacryocystorhinostomy. A minimum follow-up of 3 months was considered for final clinical analysis. Ten patients\' parents (12 surgeries) were interviewed by telephone (mean follow-up 24.8 months). No recurrence of stenosis and no further postoperative complications were observed.
    DE is a diagnostic and therapeutic option for complex CNLDO in patients before the age of 1 year. The outcome of DE in the 3 months follow-up is highly indicative of positive final results in terms of patency of the lacrimal duct.
