Anatomic mapping of acral melanocytic nevi and acral lentiginous melanomas among Taiwanese patients: A retrospective cohort study.

BACKGROUND: The early diagnosis of acral lentiginous melanoma (ALM) contributes to clinical outcomes since ALM can be mistaken for acral melanocytic nevus (AMN). ALM occurrence is reported to correlate with stress-bearing areas, which may assist in differential diagnoses. Our objective is to evaluate the distribution patterns of ALMs and AMNs on the palms and soles among Taiwanese patients. METHODS: A retrospective analysis was performed by reviewing the charts of 1400 patients diagnosed with benign and malignant pigmented lesions confirmed after excisional biopsy at our institution between 2000 and 2022 in Taiwan. Correlations between lesions and clinicopathological factors were analyzed. RESULTS: 309 AMNs and 177 ALMs were included. Mechanical stress was significantly associated with plantar ALMs (weight-bearing area: 92.65 %, arch: 7.35 %, P < 0.001). Significant differences in the distribution patterns were observed for plantar ALMs compared with all AMNs (P < 0.001) and non-atypical AMNs (P < 0.001), but were not observed between palmar AMNs and ALMs. CONCLUSION: Plantar ALMs were most commonly observed on the weight-bearing areas of the soles, distinct from the distribution of all AMNs and of non-atypical AMNs. The distribution features and anatomic mapping of ALMs may facilitate the early clinical diagnosis of ALM.

A systematic review and meta-analysis of randomized control trials: efficacy of cognitive behavioral therapies for the management of functional and recurrent abdominal pain disorders in children and adolescents.

Cognitive behavioral therapy (CBT) is effective for pain relief in children and adolescents with functional abdominal pain disorders (FAPDs). However, few studies have focused on the FAPDs specifically and the medium-term or long-term results of CBT. In this meta-analysis, we investigated the efficacy of CBT in pediatric FAPDs and unclassified chronic or recurrent abdominal pain (CAP and RAP, respectively). We searched the PubMed, Embase, and Cochrane Library databases for related randomized controlled trials until August 2021. Eventually, 10 trials with 872 participants were included. The methodological quality of the studies was assessed, and data on two primary and four secondary outcomes of interest were extracted. We used the standardized mean difference (SMD) to measure the same outcome, and precisions of effect sizes were reported as 95% confidence intervals (CIs). We found that CBT had significantly positive effects on reducing pain intensity immediately (SMD: -0.54 [CI: -0.9, -0.19], p = 0.003), 3 months after the intervention (SMD: -0.55; [CI: -1.01, -0.1], p = 0.02) and 12 months after the intervention (SMD: -0.32; [CI: -0.56, -0.08], p = 0.008). CBT also reduced the severity of gastrointestinal symptoms, depression, and solicitousness, improved the quality of life and decreased the total social cost. Future studies should consider uniform interventions in the control group and comparing different CBT delivery methods.

Chen's Double Eyelid Fold Illusion: An Eye Size Assimilation Illusion Induced by a Supratarsal Fold in the Brow-Eye Unit, A Preliminary Report.

BACKGROUND: Double eyelidplasty can enhance the eye size and facial attractiveness of Asian individuals with single eyelids. The authors hypothesize that a supratarsal fold can induce an eye size assimilation illusion to enhance eye dimensions and aesthetics, and seek to define the optimum vertical proportion between a supratarsal fold and the eye fissure associated with maximal induction of the size assimilation illusion. METHODS: A photometric study of the replicated photographs of ten female Taiwanese patients after double eyelidplasty was designed. Each photograph was edited by shifting the supratarsal folds vertically at a regular fold/eye ratio increment of 0.1. The perceived attractiveness of edited photographs of each patient was rated by 100 adult observers using a score of 1-5. The palpebral parameters were measured and analyzed. RESULTS: The mean rating score increased gradually when a supratarsal fold was added and peaked when the fold/eye ratio was 0.3 and the mean Chen's double eyelid fold ratio was 0.631 ± 0.023. After the peak, the mean score decreased gradually and was lower than the photograph without a fold when the fold/eye ratio exceeded 0.5 and the mean Chen's ratio exceeded 0.729 ± 0.027. CONCLUSION: Within the optimal ranges of the fold/eye ratio and Chen's double eyelid fold ratio, eyes are perceived as larger and more attractive due to a hybrid presentation of two interdependent eye size assimilation illusions induced by a supratarsal fold in the brow-eye unit. "Chen's double eyelid fold illusion" is proposed to describe this complex visual phenomenon. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Correction of Sunken Upper-Eyelid Deformity in Young Asians by Minimally-Invasive Double-Eyelid Procedure and Simultaneous Orbital Fat Pad Repositioning: A One-Year Follow-up Study of 250 Cases.

BACKGROUND: Double-eyelid procedure to construct a supratarsal fold is the most common aesthetic surgery in young Asian adults. More complex surgical procedures, such as fat grafting or filler injection, are often indicated during traditional, long-incision, double-eyelid procedures to achieve better aesthetic results for patients with hollowness of the upper eyelids. OBJECTIVES: The authors sought to determine the efficacy of minimally-invasive double-eyelid procedures with concurrent repositioning of the orbital fat pads to correct sunken upper eyelids in young Asian adults. METHODS: The study included 250 patients treated between June 2008 and July 2103. Preoperatively, all patients complained of upper-eyelid hollowness and had positive findings on a lower-eyelid compression test. All patients underwent a minimally-invasive double-eyelid procedure plus repositioning of orbital fat. RESULTS: After the minimum follow-up period of 1 year, the overall patient satisfaction rate was 76%. The relapse rate was 10% within the first year, and the complication rate was 8%. CONCLUSIONS: This minimally-invasive combination procedure may be an option for young Asian adults who have single upper eyelids and sunken eyes. The surgery resulted in a natural double eyelid and more youthful orbital appearance in the majority of patients in this study. Proper patient selection and evaluation, including lower eyelid compression testing, are essential to achieve long-term correction.

Effectiveness of Tai Chi on fibromyalgia patients: A meta-analysis of randomized controlled trials.

OBJECTIVE: To identify empirical evidence on the effectiveness of Tai Chi in treating fibromyalgia (FM). METHOD: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare the effectiveness of Tai Chi and standard care or conventional therapeutic exercise in patients with FM. PubMed, Medline, and Physiotherapy Evidence Database were searched for relevant studies published before May 2019. Treatment effectiveness was evaluated using the fibromyalgia impact questionnaire (FIQ), and the total score, pain score, sleep quality index, fatigue, depression, and quality of life were assessing among the patients. RESULTS: Six RCTs with 657 patients were included. Results of our meta-analysis indicated that Tai Chi exerts significant positive effects on reducing the total FIQ score at 12-16 weeks (standard mean difference [SMD]: -0.61; 95% confidence interval [CI]: -0.90 to -0.31) and pain score (SMD: -0.88; 95% CI: -1.58 to -0.18), improving sleep quality (SMD: -0.57; 95% CI: -0.86 to -0.28), relieving fatigue (SMD: -0.92; 95% CI: -1.81 to -0.04), alleviating depression (SMD: -0.49; 95% CI: -0.97 to -0.01), and enhancing quality of life physically (SMD: 6.21; 95% CI: 3.18-9.24) and psychologically (SMD: 5.15; 95% CI: 1.50-8.81). CONCLUSION: Tai Chi exerts significantly greater effects on patients with FM than standard care; therefore, we suggest that Tai Chi can be used as an alternative treatment. However, more large-scale, high-quality, and multicenter trials are required to provide stronger evidence on the effectiveness of Tai Chi, as an alternative to aerobic exercise, compared with conventional therapeutic exercise.
