Practicality and Hemodynamic Advantage of Microvascularly Augmented Pectoralis Major Musculocutaneous Flap: Technical Approach and Evidence Based on Indocyanine Green Angiography.

ABSTRACT: We have recently shown that including the blood flow from the lateral thoracic artery (LTA) in addition to the thoracoacromial artery in the pectoralis major muscle musculocutaneous (PMMC) flap (bipedicle PMMC flap) can increase the perfusion of the flap. We also developed the concept of the supercharged PMMC flap, in which the LTA included in the flap was once cut and anastomosed to a cervical artery under a microscope. It is an effective solution to maintain the additional blood flow from the LTA, when the length of the LTA is compromised for reconstruction. The mandibular reconstruction of an oral cancer patient was performed with a supercharged PMMC flap. Intraoperative indocyanine green angiography was performed in a single pedicle, bipedicle, and supercharged conditions, and the videos were analyzed with a quantitative assessment system of perfusion using some parameters. As a result, blood supply from the LTA was essential for flap survival in this patient, and supercharging from the cervical artery improved flap perfusion compared with the perfusion in the bipedicle condition. The supercharged PMMC flap can resolve the compromise of pedicle length and be also hemodynamically advantageous, thus making the reconstruction more reliable than the conventional technique.

The 'Invisible Lazy-T' Procedure for Correction of Medial Ectropion.

No accepted standard for the correction of medial ectropion has been established. The most critical part of the surgical treatment for medial ectropion is the tightening of both horizontal and vertical laxity. To correct this ectropion, we have applied a combination procedure which includes tightening of the conjunctiva and the eyelid retractors (posterior lamellae) and the lateral tarsal strip procedure. Our imitation of the 'Lazy-T', a surgical operation performed on the medial ectropion, is tentatively named 'Invisible Lazy-T'. It is a versatile technique with a less visible scar than alternative techniques because skin incision is made along the crease line of the 'the crow's feet'. Results suggest a satisfactory solution to this problem and with better outcomes than by other techniques. We propose this novel combination technique is the best strategy for the medial ectropion, and it does not require specialized surgical skill, so ectropion can be managed by craniofacial surgeons.

Emerging structural and pathological analyses on the erectile organ, corpus cavernous containing sinusoids.

Background: The corpus cavernosum (CC) containing sinusoids plays fundamental roles for erection. Analysis of pathological changes in the erectile system is studied by recent experimental systems. Various in vitro models utilizing genital mesenchymal-derived cells and explant culture systems are summarized. Methods: 3D reconstruction of section images of murine CC was created. Ectopic chondrogenesis in aged mouse CC was shown by a gene expression study revealing the prominent expression of Sox9. Various experimental strategies utilizing mesenchyme-derived primary cells and tissue explants are introduced. Main Findings: Possible roles of Sox9 in chondrogenesis and its regulation by several signals are suggested. The unique character of genital mesenchyme is shown by various analyses of external genitalia (ExG) derived cells and explant cultures. Such strategies are also applied to the analysis of erectile contraction/relaxation responses to many signals and aging process. Conclusion: Erectile dysfunction (ED) is one of the essential topics for the modern aged society. More comprehensive studies are necessary to reveal the nature of the erectile system by combining multiple cell culture strategies.

Repetitive peripheral magnetic stimulation for impairment and disability in people after stroke.

BACKGROUND: Repetitive peripheral magnetic stimulation (rPMS) is a non-invasive treatment method that can penetrate to deeper structures with painless stimulation to improve motor function in people with physical impairment due to brain or nerve disorders. rPMS for people after stroke has proved to be a feasible approach to improving activities of daily living and functional ability. However, the effectiveness and safety of this intervention for people after stroke remain uncertain. This is an update of the review published in 2019. OBJECTIVES: To assess the effects of rPMS for improving activities of daily living and functional ability in people after stroke. SEARCH METHODS: We searched the Cochrane Stroke Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL), in the Cochrane Library; MEDLINE; Embase; the Cumulative Index to Nursing and Allied Health Literature (CINAHL); PsycINFO; the Allied and Complementary Medicine Database (AMED); OTseeker: Occupational Therapy Systematic Evaluation of Evidence; the Physiotherapy Evidence Database (PEDro); Ichushi-Web; and six ongoing trial registries on 5 October 2021. We screened reference lists and contacted experts in the field. We placed no restrictions on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: We included randomised controlled trials (RCTs) conducted to assess the therapeutic effect of rPMS for people after stroke. The following comparisons were eligible for inclusion: 1) active rPMS only compared with 'sham' rPMS (a very weak form of stimulation or a sound only); 2) active rPMS only compared with no intervention; 3) active rPMS plus rehabilitation compared with sham rPMS plus rehabilitation; and 4) active rPMS plus rehabilitation compared with rehabilitation only. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion in the review. The same review authors assessed methods and risk of bias, undertook data extraction, and evaluated the certainty of the evidence using the GRADE approach. We contacted trial authors to request unpublished information if necessary. Any disagreements were resolved through discussion. MAIN RESULTS: We included four trials (three parallel-group RCTs and one cross-over trial) involving a total of 139 participants. This result was unchanged from the review published in 2019. Blinding of participants and physicians was well reported in three trials, with no information on whether personnel were blinded in one trial. We judged the overall risk of bias across trials as low. Only two trials (with 63 and 18 participants, respectively) provided sufficient information to be included in the meta-analysis. We found no clear effect of rPMS on activities of daily living at the end of treatment (mean difference (MD) -3.00, 95% confidence interval (CI) -16.35 to 10.35; P = 0.66; 1 trial; 63 participants; low-certainty evidence) and at the end of follow-up (MD -2.00, 95% CI -14.86 to 10.86; P = 0.76; 1 trial; 63 participants; low-certainty evidence) when comparing rPMS plus rehabilitation versus sham rPMS plus rehabilitation. We found no statistical difference in improvement of upper limb function at the end of treatment (MD 2.00, 95% CI -4.91 to 8.91; P = 0.57; 1 trial; 63 participants; low-certainty evidence) and at the end of follow-up (MD 4.00, 95% CI -2.92 to 10.92; P = 0.26; 1 trial; 63 participants; low-certainty evidence) when comparing rPMS plus rehabilitation versus sham rPMS plus rehabilitation. We observed a decrease in spasticity of the elbow at the end of follow-up (MD -0.41, 95% CI -0.89 to 0.07; 1 trial; 63 participants; low-certainty evidence) when comparing rPMS plus rehabilitation versus sham rPMS plus rehabilitation. In terms of muscle strength, rPMS treatment was not associated with improved muscle strength of the ankle dorsiflexors at the end of treatment (MD 3.00, 95% CI -2.44 to 8.44; P = 0.28; 1 trial; 18 participants; low-certainty evidence) when compared with sham rPMS. No studies provided information on lower limb function or adverse events, including death. Based on the GRADE approach, we judged the certainty of evidence related to the primary outcome as low, owing to the small sample size of the studies. AUTHORS' CONCLUSIONS: There is insufficient evidence to permit the drawing of any conclusions about routine use of rPMS for people after stroke. Additional trials with large sample sizes are needed to provide robust evidence for rPMS after stroke.

Immediate effect of different ankle-foot orthosis functions with the same dorsiflexed setting of initial ankle joint angle on walking ability in individuals with chronic stroke: a randomized crossover trial.

[Purpose] To investigate how different ankle-foot orthosis functions with the same dorsiflexed setting of initial ankle joint angle affect the walking ability in individuals with chronic stroke. [Participants and Methods] In this randomized crossover study, participants underwent a 10-m walking test and walked on a WalkWay MW-1000 three times under these conditions: (1) without ankle-foot orthosis; (2) with ankle-foot orthosis with an adjustable posterior strut at 5° of fixed dorsiflexion; and (3) with ankle-foot orthosis with an adjustable posterior strut at 5-20° of restricted dorsiflexion. The primary outcome was walking speed on the 10-m walking test. The secondary outcomes were walking speed and spatiotemporal factors measured by the WalkWay MW-1000. [Results] Fifteen individuals (mean [standard deviation] age, 60.9 [8.6] years; male, 12) were enrolled. Walking speeds of the ankle-foot orthosis with fixed and restricted dorsiflexion groups were significantly higher than those without the orthosis; however, no outcomes differed significantly between ankle-foot orthosis with fixed versus restricted dorsiflexion groups. [Conclusion] In individuals with chronic stroke, ankle-foot orthosis function may be less important than the dorsiflexed setting of initial ankle joint angle in the ankle-foot orthosis.

Anatomic Approximation Approach to Bilateral Macrostomia Repair.

ABSTRACT: In principle, reconstruction in macrostomia requires symmetry and accurate positioning of the newly reconstructed commissure. The proper position of the new commissure can be determined by several methods. In the determination of the new commissure of bilateral cases, generally the average length of the lips or the distance from anatomical landmarks other than the lips, such as the pupils or tragi, has been used. A new approach was reported by Tse et al in 2018: the anatomic approximation approach. Macrostomia repair refers to anatomical landmarks in the lips to determine the new commissure. The authors performed surgery using this anatomic approximation approach for bilateral macrostomia and achieved the good results.

Swinging Eyelid Approach to Zygomaticomaxillary Complex Fracture.

A surgical approach to zygomaticomaxillary complex (ZMC) fracture has not been standardized. The authors reviewed 15 cases of ZMC fractures treated with the swinging eyelid approach and evaluated the effectiveness of the technique by an observational study of Japanese patients. Results were assessed from authentic and functional perspectives: the presence of entropion/ectropion, external canthal malposition and chemosis of the conjunctiva. After a minimum follow-up of 10 months, no patients had lower eyelid ectropion, entropion or retraction. Wounds appeared inconspicuous, and a lateral canthal shape was preserved. No post-operative chemosis of the conjunctiva was observed. Each case was evaluated based on patient satisfaction about their aesthetic outcomes. Patient self-assessment is classified into 4 groups (excellent, good, fair, and unsatisfactory). Thirteen patients were assessed to have an "excellent" outcome, and 2 patients were assessed to have a "good" outcome. No patients had "fair" or "unsatisfactory" outcomes. Avoidance of scarring is a goal of every craniofacial surgeon. The swinging eyelid approach to ZMC fractures offers a simple alternative to the conventional technique. It is versatile and provides sufficient exposure to surgical fields with less visible scar because skin incision is made along the natural crease line, "the crow's feet."

Significance of the Lateral Thoracic Artery in Pectoralis Major Musculocutaneous Flap Reconstruction: Quantitative Assessment of Blood Circulation Using Indocyanine Green Angiography.

Free tissue transfer is the preferred reconstruction option in most major head and neck reconstructions. The pectoralis major muscle musculocutaneous (PMMC) flap is commonly used in salvage of necrotic free flaps and is the first choice for patients who are not candidates for free flaps. The lateral thoracic artery (LTA), which is thought to contribute to blood perfusion of the inferior and lateral mammary area, is not preserved in a conventionally harvested PMMC flap. With regard to blood supply, it has been suggested that the LTA should be preserved, in addition to the pectoral branch of the thoracoacromial artery, when a skin island is designed in the lower chest to attain a pedicle length sufficient for head and neck reconstruction. However, an effect on hemodynamic improvement using the LTA has not been shown quantitatively. In this study, we examined 8 patients with oral cancer who underwent reconstruction procedures with a bipedicle PMMC flap that included the LTA, in addition to the thoracoacromial artery. Intraoperative indocyanine green angiography was performed to examine circulation to the PMMC flap with or without LTA clamping after harvesting. After image processing, data were analyzed using a new quantitative perfusion assessment system with parameters that we recently established for assessment of peripheral arterial disease of the lower limbs. All patients had good clinical courses with whole-flap survival, no vascular insufficiency of the skin island, and no fistula formation. Intraoperative indocyanine green angiography showed an increased inflow rate into the skin island in an LTA-declamped condition in all cases, implying that the preserved LTA increased the blood supply to skin islands in the pectoralis major muscle. We conclude that preserving the LTA in a PMMC flap can increase blood perfusion and stabilize the vascularity of the flap, making the reconstruction more effective and reliable than with use of a conventionally harvested flap. Therefore, it is worthwhile to preserve the LTA as a major contributor to a lateral and distal PMMC flap.

Successful human epidermal growth receptor 2-targeted therapy beyond disease progression for extramammary Paget's disease.

Extramammary Paget's disease is a malignant intraepithelial carcinoma, which constitutes less than 1 % of all vulvar malignancies. Surgical resection is the first treatment of choice and standard chemotherapy has not been established for advanced or recurrent disease. Experimental and clinical studies have identified human epidermal growth receptor 2 as a potential therapeutic target. A 63-year-old male was referred for recurrent extramammary Paget's disease after surgery. Human epidermal growth receptor 2 was shown to be overexpressed and amplified by immunohistochemical analysis and fluorescence in situ hybridization analysis, respectively. After two cycles of trastuzumab monotherapy, all lymph node metastases decreased in size. However, he experienced recurrence in the lymph nodes during the seven courses of trastuzumab. As a subsequent treatment, trastuzumab was administered in combination with docetaxel and pertuzumab; clinical response was sustained for 12 months without significant adverse events.

What Is the Best Way to Handle the Involutional Blepharoptosis Repair?

There are many different operations to correct involutional blepharoptosis (IB); however, the outcome of the corrective surgery is rather unpredictable, regardless of the procedure employed. A reasonably predictable outcome can be achieved with careful intraoperative evaluation of the condition, with measuring of the margin reflex distance-1 (MRD-1) in supine position of the patients. With these prepositions, we collected data that indicated that our approach can achieve a predictable outcome. This was a prospective study of 21 consecutive patients (8 men and 13 women) involving 42 eyelids with IB. IB was defined as an MRD-1 of <2  mm. All 21 patients were informed of the purposes of the study, and underwent levator aponeurosis advancement. The MRD-1 was measured intraoperatively with the patients in a supine position and in the 3-month postoperative inspection with the patients in a sitting position. Statistical analyses using paired t-tests were performed. From intraoperative measurement, mean MRD-1 values were 4.31  mm on the right side (range 3.0-4.5) and 4.29  mm on the left side (range 3.5-5.0). Three months after the operations, mean MRD-1 values were 3.07  mm on the right side (range 1.5-4.0) and 3.07  mm on the left side (range 2.0-4.0). Compared with the intraoperative MRD-1 measurements, those of the postoperatives were significantly 1.2  mm reduced (right: P < 0.01, left: P < 0.01). The intraoperative measurement of MRD-1 without changing position of patients could result in successful outcome of the operation.

Surgical results of retroauricular fascia graft in frontalis suspension surgery: A case series study.

Frontalis suspension surgery is commonly used for the repair of congenital ptosis and involutional blepharoptosis with poor levator function. Grafts for this procedure have been developed using a variety of different materials, each with advantages and disadvantages. The retroauricular fascia graft might be beneficial in this surgery. This article reports the surgical results of blepharoptosis, who were treated with the retroauricular fascia, which is a new autologous graft for the frontalis suspension technique. This case series study targeted patients with ptosis who underwent frontalis suspension surgery with the retroauricular fascia graft at Wakayama Medical University in Japan between May 2016 and May 2023. Patients with insufficient follow-up (<6 months) were excluded from the study. Eligible patients were categorized into one of the following three assessment groups: "good" (improvement of palpebral fissure height without laterality, Margin reflex distance-1 gap between right and left side <0.5 mm), "fair" (improvement of palpebral fissure height with laterality), or "poor" (poor improvement of palpebral fissure height). Thirty-five eyes in 25 patients were treated with the retroauricular fascia graft. The mean postoperative follow-up was 27 months. Eight patients were classified as good (32%), 15 as fair (60%), and two as poor (8%). Two patients (8%) had postoperative lagophthalmos. No patients had eyelash inversion, tarsal deformity, or recurrence of ptosis. Scars along the edge of the hairline were inconspicuous and there were no hypertrophic scars. Functional reconstruction of the eyelids using the retroauricular fascia graft technique is described here for the first time. This grafting technique may be a useful alternative for frontalis suspension surgery because it can be harvested with easy access and without leaving conspicuous scars.

Functional outcomes of protocol-based rehabilitation for patients with coronavirus disease 2019 in an acute care setting.

Objectives: To examine the functional outcomes of patients with coronavirus disease 2019 (COVID-19) who underwent a new protocol-based rehabilitation program. Methods: In this retrospective cohort study, we enrolled patients who were hospitalised in a university hospital in Japan because of COVID-19 from 1st September, 2020-5th July, 2021. The primary outcome was the Functional Independence Measure (FIM) subtotal score for motor items at discharge. The secondary outcomes included the FIM cognitive subtotal score, length of hospital stay, rehabilitation period, total rehabilitation time, final rehabilitation protocol level, and discharge destination. Results: Of the 78 enrolled patients (49 men; mean age [standard deviation], 70.3 [13.9] years), 24 died (30.8%) during hospitalisation. Disease severity was classified as mild, moderate I, moderate II, and severe in 1, 6, 41, and 30 patients, respectively. The FIM motor subtotal score differed significantly among groups for all participants (p=0.027). Post hoc analysis revealed that the FIM motor subtotal score in the severe group was significantly lower than that in the moderate II group (p=0.030). Conclusions: Disease severity significantly affected patients' functional outcome for COVID-19 at discharge. Our protocol-based program provides a benchmark for COVID-19 rehabilitation in an acute care setting.

Incidents and Sudden Patient Deteriorations Occurring During Their Rehabilitation Sessions in an Acute Care Hospital: A Retrospective Cohort Study.

Objective: To investigate the occurrence of incidents and sudden deteriorations during rehabilitation in an acute care setting by disease category based on the International Classification of Diseases and Related Health Problems, 10th Revision. Design: Retrospective cohort study. Setting: University hospital in Japan with 1376 beds. Participants: A total of 49,927 patients who were admitted to the acute care wards and underwent rehabilitation over 8 years, from April 1, 2013, to March 31, 2021. Interventions: Rehabilitation in an acute care setting. Main Outcome Measures: Incidents and sudden deteriorations reported in medical charts. Results: Among 49,927 admissions, 455 incidents and 683 sudden deteriorations occurred during rehabilitation. The incidents and sudden deteriorations occurred at rates of 0.009/person (0.50 case/1000 h) and 0.012/person (0.75 case/1000 h), respectively. The 3 most frequent incidents were "route-related incidents" (178 cases, 39.1%), followed by "bleeding/abrasions" (131 cases, 28.8%) and "falls" (125 cases, 27.5%). Among 12 disease categories with over 500 admissions and 10,000 rehabilitation hours, the highest incident rate occurred in "certain infectious and parasitic diseases" (0.81 case/1000 h), followed by "diseases of the musculoskeletal system and connective tissue" (0.67 case/1000 h) and "diseases of the genitourinary system" (0.66 case/1000 h). The commonest sudden deterioration was "vomiting" (460 cases, 67.3%), followed by "decreased level of consciousness (with reduced blood pressure)" (42 cases, 6.1%) and "seizure" (39 cases, 5.7%). Furthermore, the highest sudden deterioration rate was in the "endocrine, nutritional, and metabolic diseases" (1.19 case/1000 h) category, followed by "neoplasms" (1.04 case/1000 h) and "certain infectious and parasitic diseases" (0.99 case/1000 h). Conclusions: An incident and sudden deterioration occurred every 2000 and 1333 h, respectively, during rehabilitation. Therefore, understanding the actual occurrence of incidents and sudden deteriorations during rehabilitation may provide valuable insights into preventing incidents and emergencies.

Effect of Post-stroke Depression on Functional Outcomes of Patients With Stroke in the Rehabilitation Ward: A Retrospective Cohort Study.

Objective: To investigate the prevalence of post-stroke depression in a rehabilitation ward and elucidate its effect on functional improvement and outcomes. Design: Retrospective cohort study. Setting: A convalescent rehabilitation ward at a University Hospital. Participants: A total of 114 patients with stroke (mean [SD] age, 67.2 [13.5] years; men, 76) assessed at 2 weeks after admission using the Mini-International Neuropsychiatric Interview were enrolled. Main Outcome Measure: Functional independence measure (FIM) efficiency during hospitalization in the ward. Results: Eleven patients (9.6%) had depression based on the Mini-International Neuropsychiatric Interview. Total FIM efficiency and FIM efficiency in the subtotal of motor items were significantly higher in the non-depression group than in the depression group (median [interquartile range]: 0.69 [0.39-0.95] vs 0.41 [0.24-0.63], P=.027; and 0.56 [0.38-0.80] vs 0.42 [0.18-0.49], P=.023, respectively). Patients in the non-depression group had higher FIM scores at discharge (median [interquartile range]: 116.0 [104.5-123.0] vs 104.0 [82.5-112.0], P=.013, respectively), and were more likely to be discharged home (80.6% vs 36.4%, P=.003). Furthermore, patients in the depression group also stayed significantly longer in the ward (71.0 [36.1] vs 106.1 [43.3], P=.010). Conclusions: Patients with post-stroke depression showed poorer efficiency of functional recovery than those without depression. A future multicenter study with a larger sample size is needed to verify these findings.

Prediction of stroke patients' bedroom-stay duration: machine-learning approach using wearable sensor data.

Background: The importance of being physically active and avoiding staying in bed has been recognized in stroke rehabilitation. However, studies have pointed out that stroke patients admitted to rehabilitation units often spend most of their day immobile and inactive, with limited opportunities for activity outside their bedrooms. To address this issue, it is necessary to record the duration of stroke patients staying in their bedrooms, but it is impractical for medical providers to do this manually during their daily work of providing care. Although an automated approach using wearable devices and access points is more practical, implementing these access points into medical facilities is costly. However, when combined with machine learning, predicting the duration of stroke patients staying in their bedrooms is possible with reduced cost. We assessed using machine learning to estimate bedroom-stay duration using activity data recorded with wearable devices. Method: We recruited 99 stroke hemiparesis inpatients and conducted 343 measurements. Data on electrocardiograms and chest acceleration were measured using a wearable device, and the location name of the access point that detected the signal of the device was recorded. We first investigated the correlation between bedroom-stay duration measured from the access point as the objective variable and activity data measured with a wearable device and demographic information as explanatory variables. To evaluate the duration predictability, we then compared machine-learning models commonly used in medical studies. Results: We conducted 228 measurements that surpassed a 90% data-acquisition rate using Bluetooth Low Energy. Among the explanatory variables, the period spent reclining and sitting/standing were correlated with bedroom-stay duration (Spearman's rank correlation coefficient (R) of 0.56 and -0.52, p < 0.001). Interestingly, the sum of the motor and cognitive categories of the functional independence measure, clinical indicators of the abilities of stroke patients, lacked correlation. The correlation between the actual bedroom-stay duration and predicted one using machine-learning models resulted in an R of 0.72 and p < 0.001, suggesting the possibility of predicting bedroom-stay duration from activity data and demographics. Conclusion: Wearable devices, coupled with machine learning, can predict the duration of patients staying in their bedrooms. Once trained, the machine-learning model can predict without continuously tracking the actual location, enabling more cost-effective and privacy-centric future measurements.

An open competition involving thousands of competitors failed to construct useful abstract classifiers for new diagnostic test accuracy systematic reviews.

There are currently no abstract classifiers, which can be used for new diagnostic test accuracy (DTA) systematic reviews to select primary DTA study abstracts from database searches. Our goal was to develop machine-learning-based abstract classifiers for new DTA systematic reviews through an open competition. We prepared a dataset of abstracts obtained through database searches from 11 reviews in different clinical areas. As the reference standard, we used the abstract lists that required manual full-text review. We randomly splitted the datasets into a train set, a public test set, and a private test set. Competition participants used the training set to develop classifiers and validated their classifiers using the public test set. The classifiers were refined based on the performance of the public test set. They could submit as many times as they wanted during the competition. Finally, we used the private test set to rank the submitted classifiers. To reduce false exclusions, we used the Fbeta measure with a beta set to seven for evaluating classifiers. After the competition, we conducted the external validation using a dataset from a cardiology DTA review. We received 13,774 submissions from 1429 teams or persons over 4 months. The top-honored classifier achieved a Fbeta score of 0.4036 and a recall of 0.2352 in the external validation. In conclusion, we were unable to develop an abstract classifier with sufficient recall for immediate application to new DTA systematic reviews. Further studies are needed to update and validate classifiers with datasets from other clinical areas.

Study to the Effect of Involutional Blepharoptosis Surgery Using Objective and Subjective Parameters.

Background We investigate the effect of involutional blepharoptosis (IB) surgery based on dry eye symptoms by analysis using objective and subjective measures. Methods We recorded various parameters from patients that underwent levator advancement surgery for IB, totaling 125 eyes (total 65 patients, 5 unilateral, 60 bilateral). Subjective assessment comprised a questionnaire on dry eye-related quality of life score (DEQS), a summary score calculated from DEQS, and six-grade evaluation, the patient's own measure of eye comfort. Objective assessment comprised marginal-reflex distance-1 (MRD-1), measurement of tear film breakup time, and superficial keratopathy (SPK) existence by slit lamp microscope. Results Subjective assessments showed that IB patients had improvement of dry eye symptoms and eye comfort when surgery increased MRD-1. On the other hand, objective assessments showed that the presence of SPK is suspected when the postoperative MRD-1 level is 3 mm or higher. Conclusion IB surgery must not only increase MRD-1 value, but also to perform maintenance of the appropriate ocular surface condition. From our parameters, we suggest postoperative MRD-1 value should be maintained at < 3 mm to safe and effective of IB surgery.

The effect of ankle-foot orthosis on ankle kinematics in individuals after stroke: A systematic review and meta-analysis.

OBJECTIVE: To evaluate whether ankle-foot orthosis (AFO) has a beneficial effect on dorsiflexion angle increase during the swing phase among individuals with stroke and patient-important outcomes in individuals with stroke. LITERATURE SURVEY: Randomized controlled trials (RCTs), randomized crossover trials, and cluster RCTs until May 2020 were researched through CENTRAL, MEDLINE, EMBASE, PEDro, CINAHL, and REHABDATA databases. Studies reporting on AFO use to improve walking, functional mobility, quality of life, and activity limitations and reports of adverse events in individuals with stroke were included. METHODOLOGY: Two independent reviewers extracted the data and assessed the risk of bias. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations approach. SYNTHESIS: Fourteen trials that enrolled 282 individuals with stroke and compared AFO with no AFO were included. Compared with no AFO, AFO could increase the dorsiflexion angle of ankle joints during walking (mean difference [MD, 3.7°]; 95% confidence interval [CI], 2.0-5.3; low certainty of evidence). Furthermore, AFO could improve walking ability (walking speed) (MD, 0.09 [m/s]; 95% CI, 0.06-0.12; low certainty of evidence). No study had reported the effects of AFO on quality of life, adverse events, fall frequency, and activities of daily life. CONCLUSIONS: Our findings suggest that AFO improved ankle kinematics and walking ability in the short term; nonetheless, the evidence was characterized by a low degree of certainty.
