Periocular Dark Circles: Correlates of Severity

Background@#Periocular dark circles (PDCs) are a common cosmetic complaint. Grading systems based on objective measures have been used but no standard system is in place. @*Objective@#To determine factors associated with subjective and objective PDC severity. @*Methods@#Enrolled patients (n=100) completed a questionnaire comprised of demographic variables, medical history, and self-perception of PDC. Those perceiving PDC graded dissatisfaction on a 10-point scale. Clinical severity (grades 0∼4) and subtype (constitutional, post-inflammatory, vascular, shadow effects, or others) were determined. A Konica Minolta CR-400 chromameter was used to obtain colorimetry measurements (L*a*b* values). The objective average difference in darkness (ΔL*) between the periocular region and the cheek was determined. Comparisons were made using Spearman correlation coefficients (r). @*Results@#Patient dissatisfaction correlated with both clinical severity (r=0.46,p＜0.001) and the ΔL* by colorimetry (r=0.35, p=0.004). Factors associated with subjective dissatisfaction were female sex (r=0.38, p=0.002), higher Fitzpatrick skin type (r=0.42, p=0.001), fewer hours of sleep (r=–0.28, p=0.03), and use of concealer (r=0.35, p=0.004). Factors associated with objective measures were higher Fitzpatrick skin type (r=0.36, p= 0.0007 and r=0.28, p=0.009, respectively), family history of PDC (r=0.34, p＜0.001 and r=0.20, p=0.05), and history of eczema (r=0.45, p＜0.001 and r=0.20, p=0.0504). Clinical severity grading correlated with colorimetric severity (r=0.36, p=0.0003). @*Conclusion@#Overall, subjective dissatisfaction was associated with clinical severity. However, factors associated with subjective severity did not necessarily overlap with factors associated with objective severity. These findings highlight the importance of patient-reported grading. There may be added value in incorporating a component of subjective grading into the traditionally objective PDC grading scales.

Minocycline and Its Impact on Microbial Dysbiosis in the Skin and Gastrointestinal Tract of Acne Patients

BACKGROUND@#Associations between acne and gastrointestinal comorbidities suggest that microbial dysbiosis and intestinal permeability may promote inflammatory acne, a condition often managed with oral antibiotics.@*OBJECTIVE@#We performed a case-control study to investigate the skin and gut microbiota in 8 acne patients before and after receiving oral minocycline compared to controls matched by age ±5 years, sex, and race.@*METHODS@#DNA was extracted from stool samples and facial skin swabs. Sequencing of the V3V4 region of the bacterial 16S rRNA gene was performed using Illumina MiSeq and analyzed using QIIME/MetaStats 2.0 software.@*RESULTS@#Acne patients included 7 female and 1 male, ages 20~32. Shannon diversity was not significantly different between the skin (p=0.153) or gut (p < 0.999) microbiota of acne patients before and after antibiotics. The gut microbiota in pre-antibiotic acne patients compared to acne-free controls was depleted in probiotics Lactobacillus iners (p=0.001), Lactobacillus zeae (p=0.001), and Bifidobacterium animalis (p=0.026). After antibiotics, the gut microbiota of acne patients was depleted in Lactobacillus salivarius (p=0.001), Bifidobacterium adolescentis (p=0.002), Bifidobacterium pseudolongum (p=0.010), and Bifidobacterium breve (p=0.042), while the skin microbiota was enriched in probiotics Bifidobacterium longum (p=0.028) and Leuconostoc mesenteroides (p=0.029) and depleted in Staphylococcus epidermidis (p=0.009) and Prevotella nigrescens (p=0.028). At the phylum level, significant enrichment of Bacteroidetes in stool of acne patients following antibiotic treatment (p=0.033) led to a decreased Firmicutes to Bacteroidetes ratio.@*CONCLUSION@#Minocycline produces significant derangements in the microbiota of the skin and gut, including many probiotic species, highlighting the potential for more targeted antimicrobial treatments for acne.

Obesity and Hypertension in Association with Diastolic Dysfunction Could Reduce Exercise Capacity

BACKGROUND AND OBJECTIVES: Empirical evidence is lacking on the cumulative disease burden of obesity and hypertension and its impact on cardiac function and exercise capacity. The purpose of this study was to determine whether the presence of obesity and hypertension together was associated with cardiac dysfunction and exercise capacity. SUBJECTS AND METHODS: Using a retrospective study design, medical records were reviewed for echocardiographic and treadmill exercise stress test data. Subjects were grouped according to four categories: normal control, obese, hypertensive, or obese and hypertensive. RESULTS: Obese, hypertensive persons showed significantly lower Ea and E/A ratio and greater E/Ea ratio, deceleration time, left ventricular (LV) mass, and LV mass index compared to their counter parts (normal control, obese and/or hypertensive) (all p<0.05), after controlling for age and sex. After controlling for age and sex, significant differences in exercise capacity indices were found, with the obese group having shorter exercise time, lower metabolic equivalents, and lower maximal oxygen uptake than the normal control, hypertensive, or both groups (all p<0.05). The hypertensive or obese and hypertensive group had greater maximal blood pressure compared with the normal control group (all p<0.001). Obese and hypertensive persons were approximately three times more likely to have diastolic dysfunction (odd ratio=2.96, p=0.001), when compared to the reference group (normotensive, non-obese, or hypertensive only persons). CONCLUSION: Diastolic dysfunction was associated with obesity and/or hypertension. The cumulative risk of obesity and hypertension and their impact on diastolic dysfunction which could be modifiable could reduce exercise capacity.

Infliximab: Effective Therapy for Pustular Psoriasis

Pustular psoriasis is often resistant to the standard therapies used to treat psoriasis vulgaris. Methotrexate, acitretin, and cyclosporine have been reported to be beneficial in the treatment of both psoriasis vulgaris and pustular psoriasis. Unfortunately, these agents have many side effects, which frequently preclude their use, and their efficacy in pustular psoriasis is often limited. We report a patient with pustular psoriasis whose skin disease cleared after administration of infliximab, a chimeric IgG monoclonal antibody that specifically binds to human tumor necrosis factor alpha (TNF-α). Prior to treatment with infliximab, she had failed several therapeutic trials of both topical and systemic agents.
