Our findings suggest that HLA-B*15:02 is significantly associated with OXC-SJS in Asian populations (Chinese and Thai). However, the severity and incidence of OXC-SJS/TEN are less than that of CBZ-SJS/TEN. The need for preemptive HLA-B*15:02 screening should be evaluated further.
Chromoblastomycosis (CBM) is an implantation mycosis characterized by the presence of pigmented muriform cells in tissue. CBM is endemic in Taiwan, but only three formal cases have been reported to date because of underreporting. To describe and update its epidemiologic features, we report a series of 30 cases between 2003 and 2016 at a single medical center. Patients were predominately male (2.75:1). The mean age of onset was 65.9 years, and disease duration ranged from 2 months to 20 years. Diabetes was the most common comorbidity, and extremities were the most frequent sites of involvement. The lesions presented as papuloplaque, verrucous, cicatricial, targetoid, or mixed types. The dermoscopic features were variable, including red dots, white vague areas, black globules, and sand-like patterns. Among 10 Fonsecaea isolates further identified by sequencing the ITS regions of ribosomal DNA, nine were F. monophora and one was F. nubica. All but one patient received either systemic antifungal agents, surgical excision, or both. Surgical excision achieved a higher complete remission rate than the other forms of treatment did.
[reaction: see text] The title compound (1) has been synthesized via sequential Pd-catalyzed amination reactions and investigated as an intrinsic fluoroionophore. The efficiency in the synthesis of 1 strongly depends on the order of couplings among the substrates. Compound 1 displays fluorescence quenching upon the binding of transition metal ions, where the binding-triggered conformational twisting and in turn the inhibition of internal charge transfer (ICT) play an important role.
Summary
Background
Colletotrichum is a rare cause of human infection. Previous reports about Colletotrichum keratitis were limited, and most diagnoses from past reports were based on morphological distinction, which could have led to underestimation of the prevalence of Colletotrichum species.
Objective
We reported phylogenetic analysis, clinical feature and treatment outcome of molecularly diagnosed Colletotrichum keratitis in our hospital.
Patients/Methods
We recruited 65 patients with culture‐proven filamentous fungal keratitis between January 1, 2015 and December 30, 2018. Through molecular sequencing including internal transcribed spacer (ITS) and multi‐locus phylogenetic analysis of fungal DNA, seven patients were verified as infected with Colletotrichum species, and their medical records were reviewed to determine the clinical characteristics.
Results
Six of seven patients had predisposing factors including trauma (5) and immunosuppressive status (1). Six isolates were initially misidentified as other fungi through morphological identification. ITS sequencing identified the isolates belonged to two species complex (SC): C. truncatum and C. gloeosporioides; multi‐locus phylogenetic analysis enabled species identification including C. tropicale (3), C. fructicola (2), C. truncatum (1) and C. fusiforme (1). Five patients with C. gloeosporioides SC responded well to medical treatment and two patients with C truncatum SC underwent evisceration because of either no visual potential or intractable pain.
Conclusions
The molecular approach provides accurate diagnosis and raises epidemiological awareness of Colletotrichum keratitis. Through multi‐locus phylogenetic analysis, we report the human infections caused by C. tropicale, C. fructicola and C. fusiforme. We also highlight the different clinical outcomes between C. gloeosporioides SC and C. truncatum SC.
Background
Since 2007, when the anatomy of facial fat compartment was described, an increasing number of studies on the aging process of the compartment of cadavers has emerged.
Objectives
The authors evaluated the aging changes of lateral facial fat compartments on the same person.
Methods
Sixty-three patients were included in this retrospective study. All patients had magnetic resonance imaging scans with at least 4 years apart. The authors targeted the fat compartments of the superficial temporal, subcutaneous temporal, and buccal fat pad, comparing the data on different time points.
Results
The thickness of the subcutaneous temporal fat did not change significantly. The 3 diameters of the superficial temporal fat compartment all became thinner on the axial view (P < 0.05). On the sagittal view, the superficial temporal fat elongated from 38.89 mm to 43.74 mm (P < 0.05). The buccal fat compartment also lengthened from 68.73 mm to 74.39 mm (P < 0.05) and had a positive correlation with follow-up duration only.
Conclusions
The study revealed the fat compartment change on the same person with time. The temporal hollow mainly originates from the thinner part of the superficial temporal fat. The descending of the buccal fat pad aggravates the labiomandibular fold. By understanding the aging process more fully, we can rejuvenate our patients more naturally.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
