RESUMO

BACKGROUND: Psoriasis is a chronic systemic disorder with ocular involvement. OBJECTIVES: To evaluate the risk of glaucoma among patients with psoriasis. METHODS: Participants in this cohort study were selected based on Chang Gung Research Database from 1 January 2003 to 31 December 2012. Follow-up ended on 31 December 2017. The participants in the control group were matched with the psoriasis group by sex, age and index date with a 4 : 1 ratio. The hazard ratios of glaucoma were estimated using Cox regression analysis. We also evaluated the relationship between the risk of glaucoma and systemic therapies as well as phototherapy and topical corticosteroid in patients with psoriasis. RESULTS: In total, 6682 patients with psoriasis and 26 728 matched controls were enrolled. The study population was composed mainly of males accounting for 64.2% (21 445/33 410) of the study population. The psoriasis group had higher incidence rates than the control group for glaucoma (adjusted hazard ratio 1.405, 95% confidence interval, 1.051-1.879). Patients with psoriasis receiving psoralen-ultraviolet A (PUVA) therapy for > 200 sessions had an increased risk of glaucoma. CONCLUSIONS: Patients with psoriasis had an increased risk of glaucoma. Long-term PUVA therapy raised the risk of glaucoma in people with psoriasis.

RESUMO

BACKGROUND: As the demand for non-invasive esthetic procedures to maintain a youthful appearance increases, there has been growing interest in the use of autologous platelet-rich plasma (PRP) and platelet-poor plasma (PPP) for the treatment of facial aging. However, there are few studies directly comparing the efficacy of PRP and PPP for facial rejuvenation. OBJECTIVES: This study aimed to compare the efficacy of PRP and PPP for facial rejuvenation. METHODS: This single-center, double-blind, randomized controlled trial was conducted from January 1, 2022, to July 31, 2022, and included ten participants who completed the follow-up. The participants were randomly assigned to receive 2.5-mL injections of PRP and PPP on different sides of the face in three sessions with 1-month intervals. The outcome was primarily determined by blinded photographic assessments and secondly by scores of the VISIA® system during the follow-up. RESULTS: Both PRP and PPP treatments resulted in significant improvement in the Global Aesthetic Improvement Scales and Modified Fitzpatrick Wrinkle Scale for periocular Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation wrinkles, with no significant difference between the two groups. However, no improvement was observed in the Wrinkle Severity Rating Scales for nasolabial folds in either the PRP- or PPP-treated groups. Furthermore, no severe adverse events were reported. CONCLUSIONS: Both PRP and PPP are effective in treating facial photoaging. PRP exhibited slightly superior efficacy in enhancing overall skin condition, while PPP was slightly more effective in improving shallow wrinkles. This study provides valuable evidence for the use of PRP and PPP in facial rejuvenation procedures.

RESUMO

BACKGROUND: Microwave therapy is used to treat axillary hyperhidrosis and osmidrosis. Even while a "danger zone" has been identified and reports of potential complications from nerve injury have been made, there has been little real-world discussion regarding whether there is any pretreatment evaluation key factor that may lower the risk. Furthermore, the efficacy of a single treatment and the safety of high-energy therapies have not been well investigated. OBJECTIVE: The aim of this study is to demonstrate the key aspects of pre-therapeutic assessment, efficacy, and suitability of a single treatment, as well as the safety of high-energy treatments. METHODS: Fifteen patients with axillary hyperhidrosis (AH) and axillary osmidrosis (AO) between ages of 20 and 50 had pretherapeutic ultrasonography and clinical assessments performed followed by a single-pass microwave treatment using the miraDry system at energy level 5. The severity of AH and AO was evaluated using the Hyperhidrosis Disease Severity Scale and Odor-10 scale, respectively, at baseline, 1 month, 3 months, and 1 year after treatment. Adverse reactions were recorded at each point of evaluation. RESULTS: Out of 30 treatment areas, 14 have a danger zone. Female gender, a small mid-upper arm circumference, and a low body mass index (BMI) are all associated risk factors. The average Hyperhidrosis Disease Severity Scale score decreased from 3.1 ± 0.7 to 1.3 ± 0.5 (p < 0.001), while the odor-10 score declined from 7.1 ± 1.6 to 3.0 ± 1.6 (p < 0.001), indicating a significant improvement in AH and AO. Most of the unfavorable treatment effects disappeared within the first month. LIMITATIONS: This study has no objective quantitative measurement of axillary odor severity and sweat assessment. CONCLUSION: Female patients, those with a smaller mid-upper arm circumference, and those with a low BMI should be treated with extra caution, and the tumescent anesthetic dose may be increased based on safety. A high-energy microwave treatment procedure performed in a single session is a safe and effective therapeutic option with good recovery.

RESUMO

BACKGROUND: Lower eyelid aging is a complicated process, and for that reason, a comprehensive assessment of the lower eyelid is important before treatment. OBJECTIVE: This study was conducted to analyze and assess the lower eyelid aging process between different age groups of Asian women. METHODS AND MATERIALS: The authors developed the comprehensive lower eyelid age rating scale (CLEARS). The rating scale contains 3 domains and each composed of 3 items. Individuals were evaluated by the age group starting with the third decade (20-29 years) through the seventh decade (60-69 years) by 2 dermatologists working independently. RESULTS: A total of 114 cases were evaluated. The total scores of CLEARS increased significantly between each adjacent age group. The scores of the snap test and the severity of fine lines, nasojugal groove, midcheek furrow, and eye bags increased significantly from the 3rd decade. The scores of the distraction test and the severity of palpebromalar groove and malar mound begin to increase with the 4th decade. Kappa coefficients of all items achieved moderate to substantial agreement. CONCLUSION: This study describes the lower eyelid aging process among Asian women by CLEARS assessment. Lower eyelid aging becomes progressively more notable beginning with the third decade.

RESUMO

BACKGROUND: Volumetric hand rejuvenation of the dorsal hands is increasingly applied for aged, skeletonized dorsal hand skin, with prominent veins, tendons, and joints due to volumetric loss of subcutaneous fat. However, the aging process of the fatty laminae remains unexplored. OBJECTIVES: The aim of this study was to investigate the impact of aging and potential determinants on the fatty laminae to improve the therapeutic effect of volumetric injection. METHODS: This cross-sectional study enrolled 105 Taiwanese participants aged ≥20 years, divided into 5 decade-based age groups. A single blinded practitioner measured the thicknesses of the dorsal superficial lamina (DSL), dorsal intermediate lamina (DIL), and dorsal deep lamina (DDL) by ultrasonography. The potential determining factors of the laminae thickness (age, sex, BMI, and hand dominance) were analyzed. RESULTS: The thicknesses of the 3 laminae decreased with age, with the mean decrease in thickness from the 20s to >60 years of the DSL, DIL, and DDL being 0.21 mm (30.0%), 1.38 mm (63.89%), and 0.31 mm (20.95%), respectively. The decrease in DIL thickness was the greatest and most significant in subjects aged >30 years. Multiple linear regression analysis showed age to be the only determinant of thickness for the 3 laminae (all P < 0.001), although the DIL was significantly thicker in men (P < 0.001). CONCLUSIONS: Volumetric fat loss was noted in the 3 fatty laminae of dorsal hands during aging; the DIL showed the greatest progressive fat loss after the age of 30. Volumetric rejuvenation of the 3 laminae may result in the most aesthetic appearance, especially in women.

RESUMO

OBJECTIVE: We aim to compare the effect of long-term anti-seizure medication (ASM) monotherapy on the risk of death and new ischemic stroke in patients with post-stroke epilepsy (PSE). PATIENTS AND METHODS: We identified all hospitalized patients (≥ 20 years) with a primary diagnosis of ischemic or hemorrhagic stroke from 2001 to 2012 using the National Health Insurance Research Database in Taiwan. The PSE cohort were defined as the stroke patients (1) who had no epilepsy and no ASMs use before the index stroke, and (2) who had epilepsy and ASMs use after 14 days from the stroke onset. The patients with PSE receiving ASM monotherapy were enrolled and were categorized into phenytoin, valproic acid, carbamazepine, and new ASM groups. We employed the Cox regression model to estimate the unadjusted and adjusted hazard ratios (HRs) with 95 % confidence intervals (CIs) of death and new ischemic stroke within 5 years across all groups, using the new ASM group as the reference. RESULTS: Of 6962 patients with PSE using ASM monotherapy, 3917 (56 %) were on phenytoin, 1623 (23 %) on valproic acid, 457 (7 %) on carbamazepine, and 965 (14 %) on new ASMs. After adjusting for confounders, compared with new ASM users, phenytoin users had a higher risk of death in 5 years (HR: 1.64; 95 % CI: 1.06-2.55). On the other hand, all ASM groups showed a similar risk of new ischemic stroke in 5 years. CONCLUSIONS: Among patients with PSE on first-line monotherapy, compared to new ASMs, use of phenytoin was associated with a higher risk of death in 5 years.

RESUMO

OBJECTIVE: To explore whether status epilepticus affected cardiac mortality. METHODS: We used the 2008-2017 multicause mortality data of the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiological Research. The status epilepticus group included patients whose death certificates mentioned status epilepticus as contributing to death. The non-status epilepticus group included patients whose death certificates mentioned epilepsy, other and unspecified convulsions, febrile convulsions, or post-traumatic seizures, as contributing to death. The outcomes for evaluation were death certificates that indicated that myocardial infarction, arrhythmia, heart failure, or cardiac arrest (CA) was the immediate cause of death. The numbers of deaths and population sizes by categorical demographics were recorded and subjected to multiple logistic regression analysis. RESULTS: Among the 14,487 death certificates in status epilepticus group; 3080 patients (21.3%) died of CA. When clinical records were compared to autopsy data, females were at a lower risk of myocardial infarction (odds ratio [OR]: 0.55, 95% confidence interval [CI]: 0.51-0.61). Patients aged 45-65 years and older than 65 years were at a higher risk of developing all four cardiac complications. Status epilepticus was associated with higher risks of arrhythmia (OR: 1.55, 95% CI: 1.11-2.15) and CA (OR: 4.34, 95% CI: 3.49-5.39) but a reduced risk of myocardial infarction (OR: 0.42, 95% CI: 0.30-0.57) as the cause of immediate death. CONCLUSION: The frequency of CA in patients with status epilepticus increased between 2008 and 2017. Male and elderly patients were at a higher risk of cardiogenic mortality.

RESUMO

Malignant gliomas are a type of central nervous system cancer with extremely high mortality rates in humans. γ-secretase has been becoming a potential target for cancer therapy, including glioma, because of the involvement of its enzymatic activity in regulating the proliferation and metastasis of cancer cells. In this study, we attempted to determine whether γ-secretase activity regulates E-cadherin to affect glioma cell migration. The human glioma cell lines, including LN18 and LN229, and the γ-secretase inhibitors, including N-[N-(3,5-difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester (DAPT) and RO4929097, were used in this study. It was shown that γ-secretase activity inhibition by DAPT and RO4929097 could promote LN18 and LN229 glioma cell migration via downregulating E-cadherin mRNA and protein expressions, but not via affecting E-cadherin protein processing. In addition, γ-secretase activity inhibition was regulated by bone morphogenetic proteins-independent Smad5 activation in glioma cells. Moreover, endogenous Smad1 in glioma cells was found to play an important role in regulating E-cadherin expression and subsequent cell migration but did not affect DAPT-stimulated effects. These results help further elucidate the molecular mechanisms of γ-secretase activity regulation involved in controlling glioma cell malignancy. Information about a potential role for Smad1/5 activity upregulation and subsequent E-cadherin downregulation during inhibition of γ-secretase activity in the development of gliomas is therefore relevant for future research.

RESUMO

BACKGROUND AND OBJECTIVES: The picosecond (PICO) laser has been a new and promising device. But, so far, there have not been many prospective studies investigating the efficacy in acne scar treatment. This study evaluated the efficacy and safety of the dual-wavelength picosecond laser in the treatment of acne scar. STUDY DESIGN/MATERIALS AND METHODS: A total of 20 patients with skin type III-IV were enrolled in this study. Eighteen patients completed the study. All patients completed six treatment sessions within a 1-month interval. All patients were treated using both 532 and 1,064 nm fractionated dual-wavelength picosecond handpieces. In evaluation, Goodman and Baron's quantitative global acne scarring grading system (GSS) was scored by two physicians. Patients also judged the results themselves by Visual Analog Scale (VAS) and pain score. RESULTS: The average baseline score of GSS quantity and quality were 15.22 and 3.00, respectively. The final scores were 10.61 and 2.33. The average baseline of patient VAS score was 4.28. The final score was 2.00. All scores achieved statistical significance (P < 0.05). No serious long-term side effects were recorded. CONCLUSION: Acne scar treatment with the fractionated dual-wavelength picosecond laser has shown both efficacy and safety in this study. Lasers Surg.

RESUMO

BACKGROUND: Intracranial aneurysms after radiotherapy (RT) have previously been reported. However, the majority of studies were case reports. Therefore, we performed a nationwide study to explore the risk of radiation-induced intracranial aneurysms. METHODS: This study included patients diagnosed with head and neck cancer (ICD9: 140-149, 161). Intracranial aneurysms formation was identified using the following ICD9 codes: nonruptured cerebral aneurysm (ICD9:4373), aneurysm clipping (ICD9:3951). Patients who did not receive curative treatment and those with intracranial aneurysms before the diagnosis of head and neck cancer were excluded. RESULTS: In total, 70,691 patients were included in the final analysis; they were categorized into the following three groups: nasopharyngeal carcinoma (NPC) with RT, non-NPC with RT, and non-NPC without RT. Patients in the NPC with RT group had the highest risk of developing intracranial aneurysms (hazard ratio (HR) 2.57; P <  0.001). In addition, hypertension was also a risk factor of developing intracranial aneurysms (HR 2.14; P <  0.01). The mean time interval from cancer diagnosis to intracranial aneurysm formation in the NPC with RT group was 4.3 ± 3.1 years. CONCLUSIONS: Compared with the non-NPC with RT and the non-NPC without RT groups, patients with NPC who received RT had a higher risk of developing intracranial aneurysms.

RESUMO

BACKGROUND: Migraine is associated with syncope. We investigated risk factors for syncope and burden of syncope in migraine patients. METHODS: Participants were recruited from a headache clinic. All participants provided information on lifestyle, co-morbidity, syncope, headache and suicide, and completed the MIDAS and HADS questionnaires. Genetic data were available for a subset of participants. Risk of syncope in relation to participant's characteristics and migraine susceptibility loci, and risks of psychological disorders associated with syncope, were calculated using logistic regression. RESULTS: Underweight, regular tea intake, diabetes mellitus, and migraine with aura were associated with increased syncope risks, with adjusted ORs of 1.76 (95% CI 1.03-3.03), 1.84 (95% CI 1.22-2.79), 4.70 (95% CI 1.58-13.95), and 1.78 (95% CI 1.03-3.10), respectively. Preliminary results showed that rs11172113 in LRP1 was associated with syncope risks. Comorbid syncope in migraine patients was associated with increased risks of depression (OR 1.95, 95% CI 1.18-3.22) and suicide attempt (OR 2.85, 95% CI 1.48-5.48). CONCLUSION: Our study showed the potential roles of vascular risk factors in the association between migraine and syncope. Modifiable risk factors for syncope in patients with migraine include body mass index and tea intake. The debilitating psychological impact of co-morbid syncope in migraine patients warrants clinical attention of treating physicians.

RESUMO

Background Evidence of vascular dysfunction in migraine is increasing. MicroRNAs (miRs) have emerged as important regulators of vascular endothelial functions. This exploratory study investigated whether circulating levels of miRs associated with endothelial function are altered in migraine patients. Methods Thirty patients with migraine (20-50 years old) without overt vascular risk factors and 30 sex- and age-matched healthy controls participated. The levels of four miRs that regulate endothelial function (miR-155, miR-126, miR-21, and Let-7g) were quantified and expressed in terms of fold changes (2-ΔΔct) relative to mean levels in the control group. Associations of miRs levels with headache features and syncope comorbidity were explored. Results Compared to controls, migraine patients had upregulated expression of miR-155 (6.17-fold, p = 0.018), miR-126 (6.17-fold, p = 0.013), and let-7g (7.37-fold, p = 0.005). Levels of miR-155 (r = 0.375, p = 0.041) and miR-126 (r = 0.375, p = 0.041) were associated with syncope frequency in the past year in migraine patients. Migraine patients with aura have insignificant higher expression of miRs levels compared to those without. Conclusions In this pilot study, circulating levels of endothelial-specific miRs appear to be elevated in migraine patients and may be associated with syncope comorbidity.

RESUMO

Background The role of central pulsatile hemodynamics in the pathogenesis of white matter hyperintensities in migraine patients has not been clarified. Methods Sixty patients with migraine (20-50 years old; women, 68%) without overt vascular risk factors and 30 demographically-matched healthy controls were recruited prospectively. Cerebral white matter hyperintensities volume was determined by T1-weighted magnetic resonance imaging with CUBE-fluid-attenuated-inversion-recovery sequences. Central systolic blood pressure, carotid-femoral pulse wave velocity, and carotid augmentation index were measured by applanation tonometry. Carotid pulsatility index was derived from Doppler ultrasound carotid artery flow analysis. Results Compared to the controls, the migraine patients had higher white matter hyperintensities frequency (odds ratio, 2.75; p = 0.04) and greater mean white matter hyperintensities volume (0.174 vs. 0.049, cm3, p = 0.04). Multivariable regression analysis showed that white matter hyperintensities volume in migraine patients was positively associated with central systolic blood pressure ( p = 0.04) and carotid-femoral pulse wave velocity ( p < 0.001), but negatively associated with carotid pulsatility index ( p = 0.04) after controlling for potential confounding factors. The interaction effects observed indicated that the influence of carotid-femoral pulse wave velocity ( p = 0.004) and central systolic blood pressure ( p = 0.03) on white matter hyperintensities formation was greater for the lower-carotid pulsatility index subgroup of migraine patients. White matter hyperintensities volume in migraine patients increased with decreasing carotid pulsatility index and with increasing central systolic blood pressure or carotid-femoral pulse wave velocity. Conclusions White matter hyperintensities are more common in patients with migraine than in healthy controls. Increased aortic stiffness or central systolic blood pressure in the presence of low intracranial artery resistance may predispose patients with migraine to white matter hyperintensities formation.

RESUMO

BACKGROUND: The pain of acute compression fracture in the lumbar spine may be refractory to conservative treatment, and surgery is not an optimal choice for the elderly or infirm individuals. Moreover, even vertebroplasty can cause many side effects such as chemical leak, adjacent segment instability, and residual pain. Percutaneous dorsal root ganglion block (PDRGB) possibly is an alternative therapeutic option. In this study, we evaluated the efficacy of pain relief and the rate of adjacent level compression fracture in patients with acute compression fracture of the lumbar spine. METHODS: We retrospectively reviewed 40 patients with lumbar compression fracture from 2013 to 2015. The patients were treated with navigation-assisted CT-guided PDRGB with steroid at the pathological level and at the adjacent level above and below. Therapeutic response was evaluated using the Numerical Rating Scale (NRS); and an optimal, acceptable, and unfavorable outcome were analyzed. RESULTS: Among the 40 patients treated, initial pain relief on the first day was dramatic, and the average NRS did not change significantly up to the first-year follow-up. The highest percentage of a good outcome, at 90% (37.5% with an optimal outcome, 52.5% with an acceptable outcome), was reported at 1 week postoperatively. The percentage of optimal outcomes increased even at the 1-year follow-up. No adjacent compression fracture was found in the group treated with PDRGB alone at the 1-year follow-up. CONCLUSIONS: PDRGB is a simple, safe, and minimally invasive procedure that showed immediate and prolonged improvement of pain in lumbar osteoporotic compression fracture patients who failed conservative treatment or had residual pain after vertebroplasty. However, continuous medication for osteoporosis was still required.

RESUMO

To evaluate efficacy and safety of picosecond 755 nm alexandrite laser as compared to 1064 nm QS-Nd:YAG laser for melasma treatment in Asians. Twelve patients received 4 sessions of treatments at 1-month interval in a split-face manner. The right side of each patient's face received 755 nm picosecond laser, and the other side received 1064 nm QS-Nd:YAG laser. Zoom handpiece of 755 nm picosecond laser at fluence of 0.88-1.18 J/cm2 was applied. The treatment protocol used for 1064 nm QS-Nd:YAG laser was 8 mm spot size at fluence of 2.0 J/cm2 initially followed by 6 mm spot size at fluence of 3.5 J/cm2, and finishing with 4 mm spot size at 3.2 J/cm2. For both 755 nm picosecond laser and 1064 nm QS-Nd:YAG laser, the endpoint was mild erythema and swelling without petechiae. Objective evaluation with visual analogue score was conducted by two independent physicians. Subject self-assessment for each patient was conducted as well. Statistical results showed that higher pigmentation clearance rate was achieved at the 755 nm picosecond laser side after the second treatment. At the 3 months follow-up, greater clearance was observed at the 755 nm picosecond laser side compared to the 1064 nm QS-Nd:YAG side. 755 nm alexandrite picosecond laser has been observed to achieve a faster and better clearance rate for melasma compared to 1064 nm QS-Nd:YAG laser. We conclude that the 755 nm picosecond laser could be a safe and effective modality for melasma treatment in Asians.
