Speech may be affected in patients with cleft lip and palate (CLP). Professional listeners, naïve listeners, and patients may perceive speech differently. The aim of the study was to assess speech among adults treated for unilateral CLP (UCLP) as rated by naïve listeners, speech-language pathologists (SLPs), and self-assessment and to evaluate how well these ratings correlate. All patients with complete UCLP treated at the Uppsala University Hospital, Uppsala, Sweden, in 1960–1987 were invited. A total of 73 of 109 patients (67%) participated, with a mean of 35 years since the initiation of treatment. The noncleft control group consisted of 55 volunteers. All participants answered questionnaires for self-rating of speech, and their speech was audio-recorded digitally. Fourteen naïve listeners and four SLPs rated the speech individually from blinded recordings. There were more speech abnormalities among patients compared to controls according to the ratings of naïve listeners and SLPs. In controls and patients, there were positive correlations between the speech ratings by naïve listeners and SLPs r = 0.44 to 0.71, p < 0.001, Spearman). The patients were less satisfied and rated to have more speech abnormalities than controls (p < 0.001). Although adults treated for UCLP considered their speech as fairly good, they were less satisfied than noncleft controls. The agreement between ratings by naïve listeners and SLPs were good, while the agreement between these ratings and self-assessment varied widely. When assessing speech in adults treated for UCLP, differences in perception of speech abnormalities by professionals, laymen, and patients should be considered. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to investigate the incidence rate and risk factors of stroke in patients treated with bilateral TKA compared with patients with unilateral TKA. Methods: In this retrospective nationwide cohort study, we compared patients undergoing unilateral TKA or bilateral TKA using data from the Korean National Health Insurance claims database between January 1, 2009 and August 31, 2017 and included patients older than 40 years of age who underwent primary TKA by the index date as documented primary diagnosis and first additional diagnosis without a history of stroke during the preceding 1 year. We used matched Cox regression models to compare the incidence rate and risk factors of newly acquired stroke among patients treated with unilateral TKA or bilateral TKA after propensity score (PS) matching. Results: In the present study, 163,719 patients who received unilateral TKA were matched to 163,719 patients with bilateral TKA based on PS. The risk of stroke during the study period was lower in patients treated with bilateral TKA than in patients with unilateral TKA (adjusted hazard ratio [HR] 0.79). Patients who received bilateral TKA were at decreased risk of stroke when the following variables were present: advanced age (70–79 years, HR 0.76), female sex (HR 0.75), rural area (HR 0.77), small- or medium-sized hospital (HR 0.75), health insurance (HR 0.77), history of hypertension drug use (HR 0.75), congestive heart failure (HR 0.70), connective tissue disease (HR 0.71), diabetes (HR 0.77), and diabetes with complication (HR 0.76). Conclusion: The risk of stroke was lower in patients treated with bilateral TKA than in patients with unilateral TKA. Patients treated with bilateral TKA were at decreased risk of stroke when the following variables were present: age (70–79 years), female sex, health insurance, history of hypertension drug use, and comorbidities, such as congestive heart failure, connective tissue disease, and diabetes.

Prosopagnosia is a specific form of visual agnosia that impairs the ability to recognise familiar faces. Prosopagnosia is typically considered for bilateral ventro-occipitotemporal lesions involving the fusiform face area. A 72-year-old right-handed woman presented with persistent inability to recognise familiar faces after cerebral infarction. Brain magnetic resonance imaging demonstrated infarction in the right medial occipital lobe, including the lingual and fusiform gyri. She showed decreased facial recognition abilities in a face recognition test consisting of famous Koreans. This case suggests that there can be individual-specific degrees of hemispheric dominance for face processing, and unilateral right occipitotemporal lesion is sufficient to produce persistent prosopagnosia.

Introduction: Twin ectopic pregnancy is the implantation of both embryos outside of the endometrial lining occurring in 1 in 20,000 up to 1 in 125,000 pregnancies. Commonly, twin ectopic pregnancies occur inside the fallopian tube either unilateral or bilateral. Unless early diagnosis and interventions are made, it may rupture causing intraperitoneal bleeding with a high risk of maternal death. Case Report: I am reporting a rare type of ectopic pregnancy: unilateral twin ectopic pregnancy with positive cardiac activity on the left side of the fallopian tube in a 30 years old gravida III para II mother. Left side salpingectomy was done for her and discharged from the hospital after two postoperative days. Conclusion: Twin ectopic pregnancy with a live embryo is a very rare type of pregnancy that needs a high index of suspicion to diagnose and treat early to prevent complications and maternal death.

Objective: The primary course of treatment for patients with low- to intermediate-risk tonsil cancer has evolved with a shift toward primary transoral robotic surgery (TORS) or radiation therapy (RT). While favorable outcomes have been reported after deintensification via unilateral TORS or RT (uniRT), comparisons of functional outcomes between these treatments are lacking. We compared clinical outcomes (Dynamic Imaging Grade of Swallowing Toxicity [DIGEST] and feeding tube [FT]) and patient-reported swallowing outcomes (MD Anderson Dysphagia Inventory [MDADI]) based on primary treatment strategy: TORS, uniRT, or bilateral RT (biRT). Study Design: Secondary analysis of prospective cohort. Setting: Single institution. Methods: The study sample comprised 135 patients with HPV/p16+ T1-T3, N0-2b (American Joint Committee on Cancer, seventh edition), N0-1 (eighth edition) squamous cell carcinoma of the tonsil were sampled from a prospective registry. Modified barium swallow studies graded per DIGEST, FT placement and duration, and MDADI were collected. Results: Baseline DIGEST grade significantly differed among treatment groups, with higher dysphagia prevalence in the TORS group (34%) vs the biRT group (12%, P =.04). No significant group differences were found in DIGEST grade or dysphagia prevalence at subacute and longitudinal time points (P =.41). Mean MDADI scores were similar among groups at baseline (TORS, 92; uniRT, 93; biRT, 93; P =.90), subacute (TORS, 83; uniRT, 88; biRT, 82; P =.38) and late time points (TORS, 86; uniRT, 86; biRT, 87; P =.99). FT placement and duration significantly differed among primary treatment groups (FT [median days]: TORS, 89% [3]; uniRT, 8% [82]; biRT, 37% [104]; P <.001). Conclusion: While TORS and uniRT offer optimal functional outcomes related to dysphagia, results suggest that no measurable clinician-graded or patient-reported differences in swallow outcomes exist among these primary treatment strategies and biRT. Aside from baseline differences that drive treatment selection, differences in FT rate and duration by primary treatment strategy likely reflect diverse toxicities beyond dysphagia.

Purpose To identify and characterize incident cases of strabismus and interocular visual acuity among infants post lensectomy for congenital cataract. Method This was a single-centre retrospective chart review of all children aged less than 12 months who underwent lensectomy from 1st January 2014 to 1st January 2021. Cases were identified from theatre coding and electronic medical records. Cases with strabismus prior to cataract surgery were excluded. Results Seventy-five children (114 aphakic eyes) were included, 36 (48%) had unilateral cataract surgery while 39 (52%) had bilateral. The mean age at the time of cataract surgery was 3.0±2.5 months (range 1 - 10 months). The mean follow-up period was 41.2±22.8 months (range 2 -72 months). Nineteen out of 75 patients (25%) developed strabismus, most of whom (18 cases) had unilateral surgery. Out of the 19 strabismus cases recorded, esotropia was reported in 74% of the cases, followed by exotropia -16%, while esotropia associated with dissociated vertical deviation (DVD) and esotropia associated with inferior oblique each made up 5% of the population. Most children who developed strabismus [17 patients (89.5%)] had lensectomy prior to 6 months of age. A significant difference of 0.65 logMAR was recorded in the interocular visual acuity (IOVA) difference between the strabismic and non-strabismic groups, and the unilateral and bilateral lensectomy groups. Conclusion Strabismus, most commonly esotropia, is common after congenital lensectomy, particularly in those children who underwent unilateral cataract surgery, and in those less than 6 months of age. Monitoring IOVA and strabismus incidence post-cataract surgery is crucial for early intervention and amblyopia prevention., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: We investigate the association of postoperative radiotherapy (PORT) volumes and salivary function in oral cavity SCC (OSCC)., Methods: OSCC patients undergoing PORT 2005-2021 underwent modified Schirmer test (MST) pre-PORT, 6 and/or 12 months post-PORT. Hyposalivation rates were compared by PORT volumes. MVA identified predictors for chronic hyposalivation., Results: Among 165 eligible patients, 88 (53%) received bilateral, 66 (40%) ipsilateral, and 11 (7%) no-neck (primary-only) PORT. Baseline characteristics were similar, except more N2b/N2c disease received bilateral PORT vs. ipsilateral or no-neck (60% vs. 36% vs. 0%, p < 0.001). Baseline hyposalivation was similar (26% vs. 30% vs. 18%, p = 0.67). Hyposalivation occurred more frequently in bilateral vs. ipsilateral vs. no-neck PORT at 6 (90% vs. 62% vs. 9%) and 12 months (90% vs. 48% vs. 0%) (both p < 0.001). On MVA, bilateral neck PORT and smoking predicted chronic hyposalivation., Conclusion: Increasing PORT volumes predict saliva function recovery and chronic hyposalivation, informing treatment discussions., (© 2024 The Author(s).

Objectives: Lung volume reduction surgery (LVRS) is an established treatment approach for patients with severe pulmonary emphysema, enhancing lung function and quality of life in selected patients. Functional benefits and outcomes after uni- versus bilateral lung volume reduction remain a topic of debate., Methods: A retrospective analysis of patients undergoing LVRS from January 2018 to October 2022 was conducted. After encouraging initial results, the standard unilateral LVRS approach was switched to bilateral. The goal of this study was to assess the impact on functional outcomes at 3 and 6 months post-surgery compared to preoperative levels for the uni- versus the bilateral approach., Results: A total of 83 patients were included (43 bilateral, 40 unilateral). Baseline demographic and functional parameters were comparable between groups. The most common complication was prolonged air leak in 19 patients (11 in the unilateral group, 8 in the bilateral group). Two patients died perioperatively (2.4%). Overall, LVRS improved forced expiratory volume in 1 s by 8.3% after 3 and 12.5% after 6 months postoperatively compared to baseline. Bilateral surgery presented significantly superior forced expiratory volume in 1 s improvement than unilateral approach at both 3 (29.2% versus 2.9%; P = 0.0010) and 6 months (21.5% versus 3%; P = 0.0310) postoperatively. Additionally, it reduced hyperinflation (residual volume) by 23.1% after 3 months and by 17.5% after 6 months, compared to reductions of 16% and 9.1% in the unilateral group., Conclusions: Bilateral approach resulted in better functional outcomes 3 and 6 months postoperatively compared to unilateral surgery., (© The Author(s) 2024.

Background: This retrospective study aimed to evaluate the short-term recovery and cost-effectiveness of bilateral unicompartmental knee arthroplasty (UKA) compared to staged unilateral UKA. The study analyzed postoperative pain scores, medical costs, and complications in patients with knee osteoarthritis who underwent these procedures., Methods: A total of 226 patients who received either unilateral UKA (Group A, n  = 170) or bilateral UKA (Group B, n  = 56) using the mobile-bearing UKA were included in the study. Patient demographics, surgical details, postoperative pain scores, knee range of motion, length of hospital stay, self-controlled analgesic use, total medical costs, and complications were retrospectively collected from medical records., Results: The demographic characteristics were comparable between the groups. Group B had a longer surgical time and higher medical costs than Group A. However, there were no significant differences in hospital stay, pain scores, or knee range of motion between the two groups. Complications were infrequent and not significantly different. Insert dislocation and loosening were the most common complications. Patient-controlled analgesia effectively reduced pain scores in Group A but not in Group B., Conclusion: Bilateral UKA does not significantly affect hospital stay, postoperative pain, or complications compared to unilateral UKA. Although bilateral UKA requires longer surgical time and incurs higher costs, it offers the potential benefit of reducing anesthesia-related complications and overall health insurance expenditures. This study recommends bilateral UKA as a suitable option for patients with bilateral knee osteoarthritis, given its comparable short-term outcomes and potential cost-saving advantages., Level of Evidence: III., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Tu, Shih, Wang and Chen.)

Purpose: To investigate the retinal vascular abnormalities in both affected and fellow eyes of presumed unilateral Coats disease patients using ultra-widefield fluorescein angiography (UWF-FA) and their association with visual prognosis., Methods: A retrospective review of medical records was conducted on 30 patients diagnosed with presumed unilateral Coats disease, who were evaluated with UWF-FA from March 2003 to May 2024 at a tertiary referral hospital. Clinical features and multimodal imaging findings were evaluated, and factors related to final visual outcomes were analyzed., Results: All 30 patients were diagnosed with presumed unilateral Coats disease at presentation, comprising 11 childhood-onset (36.7%) and 19 adult-onset patients (63.3%). Retinal vascular telangiectasia was observed in 51.7% of the fellow eyes. The extent of telangiectasia and exudate in the affected eyes did not significantly correlate with the extent of telangiectasia in the fellow eyes. In the more affected eyes, the childhood-onset group had a significantly greater extent of capillary dropout compared to the adult-onset group (5.0 clock hours vs. 2.8 clock hours, p = 0.023). In the fellow eyes, telangiectasia tended to be more frequent in the childhood-onset group, without statistical significance (63.6% vs. 44.4%, p = 0.160). In the multivariable regression analysis, the final best-corrected visual acuity (BCVA) in the more affected eyes was significantly associated with initial BCVA. The mean extent of telangiectasia in the temporal and nasal quadrants (odds ratio, 12.759; p = 0.043) and the initial BCVA of the more affected eyes (odds ratio, 11.841; p = 0.024) were identified as prognostic factors for final moderate to severe visual loss (Snellen BCVA <20 / 66)., Conclusions: About half of the presumed unilateral Coats disease cases exhibited features of the bilateral disease. Visual prognosis is associated with the peripheral retinal telangiectasia in the temporal and nasal quadrants as well as initial BCVA in the affected eyes while it is not associated with retinal vascular abnormalities in the fellow eyes.

Background: Prostatic artery embolization (PAE) is a promising but also technically demanding interventional radiologic treatment for symptomatic benign prostatic hyperplasia. Many technical challenges in PAE are associated with the complex anatomy of prostatic arteries (PAs) and with the systematic attempts to catheterize the PAs of both pelvic sides. Long procedure times and high radiation doses are often the result of these attempts and are considered significant disadvantages of PAE. The authors hypothesized that, in selected patients, these disadvantages could be mitigated by intentionally embolizing PAs of only one pelvic side., Aim: To describe the authors' approach for intentionally unilateral PAE (IU-PAE) and its potential benefits., Methods: This was a single-center retrospective study of patients treated with IU-PAE during a period of 2 years. IU-PAE was applied in patients with opacification of more than half of the contralateral prostatic lobe after angiography of the ipsilateral PA (subgroup A), or with markedly asymmetric prostatic enlargement, with the dominant prostatic lobe occupying at least two thirds of the entire gland (subgroup B). All patients treated with IU-PAE also fulfilled at least one of the following criteria: Severe tortuosity or severe atheromatosis of the pelvic arteries, non-visualization, or visualization of a tiny (< 1 mm) contralateral PA on preprocedural computed tomographic angiography. Intraprocedural contrast-enhanced ultrasonography (iCEUS) was applied to monitor prostatic infarction. IU-PAE patients were compared to a control group treated with bilateral PAE., Results: IU-PAE was performed in a total 13 patients (subgroup A, n = 7; subgroup B, n = 6). Dose-area product, fluoroscopy time and operation time in the IU-PAE group (9767.8 μGy∙m 2 , 30.3 minutes, 64.0 minutes, respectively) were significantly shorter (45.4%, 35.9%, 45.8% respectively, P < 0.01) compared to the control group. Clinical and imaging outcomes did not differ significantly between the IU-PAE group and the control group. In the 2 clinical failures of IU-PAE (both in subgroup A), the extent of prostatic infarction (demonstrated by iCEUS) was significantly smaller compared to the rest of the IU-PAE group., Conclusion: In selected patients, IU-PAE is associated with comparable outcomes, but with lower radiation exposure and a shorter procedure compared to bilateral PAE. iCEUS could facilitate patient selection for IU-PAE., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2024.

Background: The aim of this study is to assess the ICP changes induced by a unilateral fronto-temporo-parietal DC with dural expansion after moderate to severe TBI. The effect of different bone flap sizes on ICP and the neurological outcomes were also evaluated after the decompressive surgery., Methods: 52 TBI patients with clinical and radiological evidences of increased ICP were included in this prospective study. All patients received unilateral fronto-temporo-parietal DC with dural expansion and ventriculostomy at contralateral Kocher's point. Postoperatively, ICP values and the largest antero-posterior (AP) diameter of bone flap removed was measured, and the clinical outcomes were assessed using Extended Glasgow Outcome Scale (GOS-E) at discharge and 6 months after DC., Results: The median ICP significantly decreased with an average of 56.7 % reduction from the initial opening ICP. Similar ICP changes were observed in all groups. This study also found that the large bone flap group (AP diameter >15 cm) demonstrated better postoperative ICP control as compared to the small bone flap group (AP diameter 12-15 cm), although not statistically significant. The SDH and cerebral swelling groups did better in the GOS-E at 6 months after TBI compared with cerebral contusion group., Conclusion: The ICP reduction in moderate to severe TBI patients undergoing unilateral fronto-temporo-parietal DC with dural expansion occurred in accordance with decompressive steps, regardless of intracranial lesions and the surgical procedure should be performed with the bone flap size of at least 12 cm in AP diameter for adequate and sustained ICP control., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Abstract Background Although the original technique involves inserting two cages bilaterally, there could be situations that only allow for insertion of one cage unilaterally. However, only a few studies have compared the outcomes between unilateral and bilateral cage insertion. The purpose of this study was to compare the clinical and radiological outcomes in patients who underwent posterior lumbar interbody fusion (PLIF) between unilaterally and bilaterally inserted cages. Methods Among 206 eligible patients who underwent 1- or 2-level PLIF, 78 patients were 1:3 cohort-matched by age, sex, and operation level (group U, 19 patients with unilateral cages; and group B, 57 patients with bilateral cages). Fusion status was evaluated by computed tomography (CT) scans at postoperative 1 year. Clinical outcomes were measured by visual analog scale (VAS), Oswestry Disability Index (ODI), and EQ-5D. Radiological and clinical parameters were compared between the two groups. Risk factors for pseudarthrosis were also analyzed by multivariate analysis. Results The demographic data were not significantly different between the two groups. However, previous laminectomy, asymmetric disc collapse, and fusion at L5-S1 level were more frequently found in group U (P = 0.003, P = 0.014, and P = 0.014, respectively). Furthermore, pseudarthrosis was more frequently observed in group U (36.8%) than in group B (7.0%) (P = 0.004). Back pain VAS was higher in group U at postoperative 1 year (P = 0.033). Lower general activity function of EQ-5D was observed in group U at postoperative 1 year (P = 0.035). Older age (P = 0.028), unilateral cage (P = 0.007), and higher bone mineral density (P = 0.033) were positively correlated with pseudarthrosis. Conclusions Unilaterally inserted cage might be a possible risk factor for pseudarthrosis when performing PLIF, which could be related with the difficult working conditions such as scars due to previous laminectomy or asymmetric disc collapse. Furthermore, suboptimal clinical outcomes are expected following PLIF with unilateral cage insertion at postoperative 1 year regardless of similar clinical outcomes at postoperative 2 year. Therefore, caution is advised when inserting cages unilaterally, especially under above-mentioned conditions in terms of its possible relationship with symptomatic pseudarthrosis.

Polymastia or supernumerary breast is an anomaly of the embryonic development of the mammary gland resulting in ectopic breast tissue. We report an exceptional case of a unilateral axillary supernumerary breast in a 71-year-old patient which became enlarged after menopause. The diagnosis was confirmed on anatomopathological study which revealed no sign of malignancy otherwise. In our case, it was a proliferation of glandular tissue, without areola or nipple, rarely reported in the literature, and corresponding to Kajava class IV. The patient underwent surgical treatment in order to resolve the problem of aesthetic discomfort and to limit the risk of malignant transformation.

Objectives: The association between single-joint isometric rate of force development (RFDISO) and jumping outcomes remain largely unexplored. Further, the importance of RFD assessed during jumping for jump height and duration (i.e. time from jump onset to take-off) remains ambiguous. We therefore investigated these associations in a large heterogenous sample. Design: Cross-sectional study. Methods: Three-hundred-twenty-six male and female basketball and tennis players, and physical education students performed the bilateral squat jump (SJ) and both bilateral and unilateral countermovement jumps (CMJ). Single-joint RFDISO was assessed for the hip extensors, knee extensors and ankle extensors and associations between relevant outcomes were computed. Results: Knee and hip extensors RFDISO showed small positive correlations with RFDSJ and RFDCMJ. Ankle extensors RFDISO showed a moderate positive correlation with RFDSJ and RFDCMJ. RFDISO showed small to moderate correlations with CMJ and SJ jump height, but trivial correlations with jump duration. Stepwise linear regression showed that a combination of RFDISO from different muscle groups explained a small to moderate variance in jump height (∼23–28%), duration (∼2–3%), and RFD during jumping (∼19–28%). RFDSJ showed small positive and moderate negative correlations with SJ height and duration, respectively while these correlations were small and trivial for the CMJ. Conclusions: The positive correlations between RFD during jumping and jump height, and negative correlation with jump duration imply that improving RFD during jumping could benefit jump performance. However, the mostly small correlations between single-joint RFDISO and jumping RFD suggests that single-joint RFDISO assessments provide only limited information regarding the RFD in sports-related movements.

Introduction: The muscles of posterior abdominal wall on each side of vertebral column include psoas group, quadratus lumborum and iliacus. The psoas muscle group comprises of major, minor and tertius. The psoas major is present in all individuals. Psoas minor is often absent in 40% of the cases. Psoas minor muscle has racial and morphometric variations. Aim: To find the incidence and morphology of psoas minor in South Indian population and discuss its clinical implications. Materials and Methods: The present observational cadaveric study was done on 30 embalmed cadavers for teaching purpose from November 2017 to December 2020 at Karnataka Institute of Medical Sciences, Hubballi, Karnataka, India. Cadavers in the study were of the age group between 50-60 years. Out of 30 cadavers, five were females and 25 were males. In cadavers with presence of psoas minor muscle following parameters were photographed and studied: unilateral or bilateral, origin, insertion, nerve supply, total length of musculotendinous unit, length of muscle belly, length of tendon, width and circumference at its widest point. Vernier calipers, measuring tape, scale and inelastic thread were used to note various parameters and were tabulated. Results: Out of 30 cadavers, psoas minor was present in 10 cadavers (two female and eight male), bilateral in five and unilateral in five cadavers. The incidence of presence of psoas minor muscle in the present study is 33.33% (two female 6.67% and eight male 26.67%). Conclusion: The psoas minor muscle being vestigial and inconstant, its morphology is highly variable. But the incidence of psoas minor is quiet significant (33.33%). Hence knowledge of psoas minor is important to anatomists for academic purpose and to clinicians for proper diagnosis and treatment.

Purpose: To examine the effects of unilateral resistance training on lower body power, muscular strength, and measures of core stability in resistance-trained college students. Methods: Participants (N=22; mean age= 19.86 ± 0.9 years) underwent 10 sessions of either unilateral (UL) or bilateral (BL) resistance training on three non-consecutive days per week for three weeks. Pre and post training outcome measures included one repetition maximum (1-RM) leg press for lower body strength, standing vertical jump (VJ) for lower body power, and double leg lowering (DLL), hip abduction isometric strength (HAIS), and Sorensen (SOR) tests for core stability. Results: There was a significant (p≤ 0.05) main effect of time across all variables, such that both groups improved scores on 1-RM leg press, VJ, DLL, HAIS, and SOR. Additionally, the magnitude of improvement (Cohen’s d) was larger in UL for all variables except VJ, which was larger in the BL group. Conclusion: This study adds to the growing body of literature investigating the effects of UL resistance training in athletic populations. Similar improvements following UL or BL resistance training suggest that both methods can effectively enhance strength, power, and core stability. UL training may potentially yield greater improvement of core stability variables.

Purpose: Birdshot Retinochoroiditis (BRC) is an uncommon but distinct form of bilateral posterior uveitis. It is generally of indolent onset, making early natural history difficult to study. Our report seeks to expand knowledge on the natural history of the onset of BRC. Observations: Our patient presented with clinical features that were consistent with unilateral BRC, despite it being defined as a bilateral condition. Over the course of one year he developed retinal vasculitis, vitritis and fundus features of BRC in the second eye. Conclusions and Importance: Although BRC is a bilateral disease, our case demonstrates that the onset may sometimes be sequential instead of simultaneous. Unilateral disease that is characteristic of BRC should be monitored for second-eye involvement with multi-modal imaging including fundus photography, angiography, perimetry, electroretinography, and optical coherence tomography of the macula with emphasis on the choroidal thickness.

Objective: Transcranial direct current stimulation (tDCS) has shown positive results in neurorehabilitation. However, there is limited evidence on its use in acute stroke, and unclear evidence regarding the best tDCS montage (anodal-, cathodal-, or dualtDCS) for stroke recovery. This study investigated the effects of these montages combined with physical therapy on haemodynamic response and motor performance. Methods: Eighty-two eligible acute stroke participants were allocated randomly into anodal, cathodal, dual, and sham groups. They received 5 consecutive sessions of tDCS combined with physical therapy for 5 days. Cerebral mean blood flow velocity (MFV) and motor outcomes were assessed pre and post-intervention and at a 1-month follow-up. Results: None of the groups showed significant changes in the MFV in the lesioned or non-lesioned hemispheres immediately post-intervention or at a 1-month follow-up. For motor performance, all outcomes improved over time for all groups; between-group comparisons showed that the dual-tDCS group had significantly greater improvement than the other groups for most of the lower-limb performance measures. All 5-day tDCS montages were safe. Conclusion: MFV was not modulated following active or sham groups. However, dual-tDCS was more efficient in improving motor performance than other groups, especially for lower-limb performance, with after-effects lasting at least 1 month. LAY ABSTRACT Different methods (anodal, cathodal, dual, or sham) of transcranial direct current stimulation (tDCS) combined with physical therapy were randomly provided to patients with acute stroke for 5 consecutive daily sessions. The outcome measures were evaluated before the intervention, post-intervention, and at 1-month follow-up using clinical motor assessments and transcranial colour-coded Doppler ultrasonography to measure blood flow velocity in the middle cerebral artery. The results showed no significant changes in cerebral blood flow in the lesioned and non-lesioned brain in all groups. For motor outcomes, dual-tDCS was more efficient for improving motor performance, especially lower-limb performance, than other montages, with a positive effect lasting for at least 1 month. All tDCS montages combined with physical therapy were safe for use in patients with acute stroke.

An 80-year-old woman presented with painless blurring of vision and monocular diplopia in her left eye following routine phacoemulsification and monofocal intraocular lens (IOL) implantation 5 weeks earlier. Her uncorrected visual acuity (VA) was 6/60 correctable with pinhole to 6/21. Her best-corrected VA was 6/15 with a subjective refraction of −0.50DS/−5.25DCx37. Her corneal astigmatism was −1.25DCx74. Ophthalmic examination disclosed a severely tilted single-piece posterior chamber IOL in the capsular bag. The inferior portion of the optic was tilted posteriorly because of a twisted and malpositioned haptic. The patient underwent remedial surgery to untwist and reposition the IOL haptic which led to immediate improvement of the IOL position. Her uncorrected VA improved to 6/12−2 correctable with pinhole to 12+1 with an autorefraction of +0.25DS/−2.00DCx74 on the first postoperative day. One month postoperatively, her best-corrected VA was 6/12 with a refraction of +0.50DS/−2.50DCx82. Her final vision was limited by myopic macular degeneration. [ABSTRACT FROM AUTHOR]

This study aimed to determine the characteristics of sound localization in children with unilateral microtia and atresia (UMA) and the influence of a non-surgical bone conduction device (BCD). Hearing benefits were evaluated by the word recognition score (WRS), speech reception threshold, the international outcome inventory for hearing aids (IOI-HA), and the Speech, Spatial, and Qualities of Hearing Test for Parent (SSQ-P). Sound localization was measured using broadband noise stimuli randomly played from seven loudspeakers at different stimulus levels [65, 70, and 75 dB sound pressure levels (SPLs)]. The average unaided WRS and speech-to-noise ratio (SNR) for UMA patients was 18.27 ± 14.63 % and -5 ± 1.18 dB SPL, and the average aided WRS and SNR conspicuously changed to 85.45 ± 7.38 % and -7.73 ± 1.42 dB SPL, respectively. The mean IOI-HA score was 4.57 ± 0.73. Compared to the unaided condition, the mean SSQ-P score in each domain improved from 7.08 ± 2.5, 4.86 ± 2.27, and 6.59 ± 1.4 to 8.72 ± 0.95, 7.61 ± 1.52, and 8.55 ± 1.09, respectively. In the sound localization test, some children with UMA were able to detect sound sources quite well and the sound localization abilities did not deteriorate with the non-surgical BCD. Our study concludes that for children with UMA, the non-surgical BCD provided a definite benefit on speech recognition and high satisfaction without deteriorating their sound localization abilities. It is an efficient and safe solution for the early hearing intervention of these patients. [ABSTRACT FROM AUTHOR]

Background: Vocal fold paralysis (VFP) can result from a variety of diseases or surgeries and has various causes. This study determined concurrent etiologies in patients who were treated in a teaching hospital (tertiary medical center). Methods: A retrospective review of medical records of patients with VFP from September 2010 to December 2019 was performed to determine the etiology. Patients with laryngeal/hypopharyngeal malignancies, those with incomplete examination and follow-up data were excluded from the study. During the follow-ups, cases involving recovery were also excluded. Results: One hundred and ninety-four patients with a determined etiology were included: 113 males and 81 females. Unilateral VFP was present in 178 patients, and 16 presented with bilateral VFP. The causes of unilateral VFP were surgical for 61.3%, neoplastic for 17.5%, idiopathic for 10.3%, traumatic for 1.5%, central for 4.7%, cardiovascular for 2%, radiation-induced for 1.5%, and inflammatory for 1%. Thyroidectomy was the most common surgery for unilateral VFP and was the cause for 54 patients. Lung cancer was responsible for 15 cases and was the most common neoplastic etiology of unilateral VFP. For those who presented with bilateral VFP, surgery was the most common cause and accounted for 56.3% of the incidences. In terms of gender, surgery was the most common cause for both sexes, accounting for 62 of 113 male patients and 57 of 81 female patients. Four cases recovered during the follow-ups and these were excluded. Conclusion: Surgery and in particular, thyroidectomy, was the most common cause of VFP for these series. Central nervous system disorders were the cause of VFP (4.5%). Central nervous system disorders, especially cerebrovascular accidents that induced VFP, could not be neglected. Radiation-induced cranial nerve paralysis in the head and neck cancer was possible causes. The percentage for the causes of unilateral VFP, surgery increased and the percentage for neoplasm decreased for Taiwan. [ABSTRACT FROM AUTHOR]

Bilateral adrenal neuroblastoma (NB) is rare and is mainly stage 4S. Its incidence, presenting features, management, and outcome have not been fully defined yet. We searched the Italian NB Registry (RINB) for stage 4S NB infants with bilateral adrenal primary tumor to compare them with stage 4S NB with unilateral tumor. Between 1979 and 2016, the RINB enrolled 3731 NB patients aged 0-18 years including 317 infants (8.5%) diagnosed with stage 4S NB. Eleven/317 (3.5%) had a bilateral adrenal primary tumor (Group 1) and 190/317 (59.9%) had a unilateral tumor (Group 2). Group 1 infants were significantly younger (51 vs. 89 days) but were comparable with Group 2 for any other presenting features. In the absence of specific protocols, upfront treatment was based on symptoms, size of adrenal tumors, and biology, and consisted of observation in 5 cases, radiotherapy in one, chemotherapy in 2, and surgery in 3. Five/11 developed progression and 2 of them, both with MYCN amplification, died. The 5-year EFS rates of Group 1 and 2 were 54.5% vs. 73.3% (P=.14) and 5-year OSs were 81.8% and 89.4%, respectively (P=.44). Our data support the hypothesis that 4S NB infants with bilateral adrenal tumors can have favorable outcome with personalized therapeutic approach. The three patients with MYCN amplified tumor benefited from upfront aggressive chemotherapy, in accordance with current protocols. Because of the rarity of this intriguing form of neuroblastoma, collaborative prospective studies are warranted, especially in view of gaining a better insight on its biological and genetic features.

Velocity storage is a centrally-mediated mechanism that processes peripheral vestibular inputs. One prominent aspect of velocity storage is its effect on dynamic responses to yaw rotation. Specifically, when normal human subjects are accelerated to constant angular yaw velocity, horizontal eye movements and perceived angular velocity decay exponentially with a time constant circa 15–30 s, even though the input from the vestibular periphery decays much faster (~ 6 s). Peripheral vestibular damage causes a time constant reduction, which is useful for clinical diagnoses, but a mechanistic explanation for the relationship between vestibular damage and changes in these behavioral dynamics is lacking. It has been hypothesized that Bayesian optimization determines ideal velocity storage dynamics based on statistics of vestibular noise and experienced motion. Specifically, while a longer time constant would make the central estimate of angular head velocity closer to actual head motion, it may also result in the accumulation of neural noise which simultaneously degrades precision. Thus, the brain may balance these two effects by determining the time constant that optimizes behavior. We applied a Bayesian optimal Kalman filter to determine the ideal velocity storage time constant for unilateral damage. Predicted time constants were substantially lower than normal and similar to patients. Building on our past work showing that Bayesian optimization explains age-related changes in velocity storage, we also modeled interactions between age-related hair cell loss and peripheral damage. These results provide a plausible mechanistic explanation for changes in velocity storage after peripheral damage. Results also suggested that even after peripheral damage, noise originating in the periphery or early central processing may remain relevant in neurocomputations. Overall, our findings support the hypothesis that the brain optimizes velocity storage based on the vestibular signal-to-noise ratio. [ABSTRACT FROM AUTHOR]

Objective: Ubiquitous throughout the literature and during patient counseling, vestibular schwannoma is often quoted to affect about 1 per 100,000 people. Yet, reports from distinct international populations suggest that the incidence is likely much higher. The objective of the current work was to systematically characterize the global incidence of sporadic vestibular schwannoma. Data Sources: Scopus, Embase, and PubMed. Review Methods: Population-based studies reporting incidence rates of sporadic vestibular schwannoma between January 2010 and August 2020 were searched with language restrictions requiring reports to be published in Chinese, English, German, Italian, or Spanish. The protocol was registered with PROSPERO (CRD42021228208) prior to commencement of data collection. PRISMA guidelines for transparent reporting of systematic reviews were followed. Results: Among 424 citations, 6 publications covering 4 distinct populations from Denmark, the Netherlands, Taiwan, and the United States met inclusion criteria. Most recent incidence rates of among all ages ranged between 3.0 and 5.2 per 100,000 person-years. Highest incidence rates were reported among patients aged ≥70 years, peaking at 20.6 per 100,000 person-years. One study from the United States reported the incidence of asymptomatic, incidentally diagnosed tumors at a rate of 1.3 per 100,000 person-years from 2012 to 2016. Conclusions: Recent international incidence rates of sporadic vestibular schwannoma exceed the commonly quoted "1 per 100,000" figure by up to 5-fold among all ages and by up to 20-fold among age groups at highest risk. Based on modern incidence rates, the lifetime prevalence of developing sporadic vestibular schwannoma likely exceeds 1 per 500 persons. [ABSTRACT FROM AUTHOR]

Besides examining upper and lower limb morphological and functional asymmetry magnitudes, this study examined the relationship between lean mass and functional asymmetry in terms of magnitude and direction in 41 youth tennis players versus 41 controls. Asymmetry magnitude was determined using anthropometric measurements (circumferences, widths), bioelectrical impedance analysis (lean mass) and a test battery (handgrip strength, seated medicine ball throw, plate tapping, single leg countermovement jump, single leg forward hop test, 6 m single leg hop test, 505 change of direction). ANOVAs compared the dominant (overall highest/best value) against the non-dominant (highest/best value of opposing limb) result. Linear regressions explored the relationship between lean mass and functional asymmetry magnitudes. Kappa coefficients examined asymmetry direction consistency between the limb displaying the highest lean mass value and the limb performing dominantly across tests. Significant asymmetry magnitudes (p < 0.05) were found for all upper and lower limb outcome measures. No significant relationship was apparent between lean mass and functional asymmetry magnitude (r-value = −0.283–0.262). Despite finding (almost) perfect consistency in asymmetry direction (k-value = 0.84–1.00) for the upper limb, poor to slight consistency (k-value = −0.03–0.15) was found for the lower limb. Therefore, lean mass and functional asymmetry should be examined independently. [ABSTRACT FROM AUTHOR]

Background: Moyamoya disease (MMD) is a chronic progressive cerebrovascular disease mainly existing in the Asian population, which can be divided into unilateral and bilateral types. Contralateral progression has been reported in pediatric patients with unilateral MMD, while large series about contralateral progression in Chinese adult patients were rare. The goal of this study is to elucidate the clinical features and incidence of contralateral progression in Chinese MMD adult patients. Methods: One hundred one Chinese adult patients with unilateral MMD who received surgery treatments between January 2015 and January 2017 in our hospital were enrolled in this study. This study contained 89 patients. Digital subtraction angiography was performed in all patients for initial diagnosis, and magnetic resonance angiography was repeated 6 months from the initial operation and then annually. Clinical characteristics, contralateral progression, and risk factors were studied. Previous related studies were also reviewed and meta-analyzed. Results: Of these 89 patients, contralateral progression was identified in 8 patients (9.0%) within a median follow-up period of 63 months, which was lower than that in previous studies (25.9%). Single-factor analysis and multivariate analysis did not reveal significant risk factors related to the contralateral progression. Conclusion: The progress rate in this cohort of Chinese adult patients with unilateral MMD after revascularization was 9.0%, which indicates that some of the unilateral MMD were an early form of bilateral MMD rather than a separate condition.

Purpose: Patients presenting with multiple same-sided ureteric stones (MSSUS) are a unique population with nuanced prognostic and treatment considerations, which have yet to be characterized in the literature. Therefore, our purpose was to examine outcomes of patients with MSSUS vs those with single ureteric stones (SUS). Methods: A retrospective review of prospectively collected patients included adults (> 18yo) with ≥ 2 ipsilateral ureteral stones without prior treatment for their current stone burden. A historical comparison group was used as a control population. Univariate logistic regression analyses and descriptive statistics were performed with SPSS® 20.0 (p < 0.05). Results: Seventy-nine MSSUS patients were compared to 101 SUS patients. MSSUS patients had 2.21 ± 0.66 ureteric stones and had significantly smaller lead stones (MSSUS 6.4 mm vs SUS 7.2 mm, p = 0.03). MSSUS patients were more likely to have had prior stones (66 vs 42%) and 5.9 times more likely to have had prior stone procedures. Conservative management was successful in 30% MSSUS vs 19% SUS (p = 0.073), and there were no differences in resolution time (p = 0.44). For patients proceeding to intervention, (MSSUS n = 52, SUS n = 78), ureteroscopy was performed on 58% MSSUS vs 51% SUS patients (p = 0.302), and shockwave lithotripsy in 10% MSSUS vs 26% SUS (p = 0.01). MSSUS were more likely to spontaneously pass a stone prior to planned intervention (OR = 41.1; 95% CI = 12.0–140.7; p = 0.0001). Conclusion: MSSUS patients are more likely recurrent stone formers with extensive stone histories and current stone burdens. Conservative management appears as successful between groups, with no difference in resolution time. When employed, ureteroscopy outcomes do not different between cohorts. [ABSTRACT FROM AUTHOR]

We present the case of an 11-year-old girl with a history of chronic, pulsatile cephalic failure with no neurological data on neurological examination. The bony window of the computed tomography, showed absence of the left carotid canal. Subsequent T2-weighted images and magnetic resonance angiography show absence of the left internal carotid artery. These data were confirmed by a cerebral panangiography. The literature mentions internal carotid artery agenesis as a very rare congenital vascular anomaly, occurring in less than 0.01% of the population. Usually asymptomatic, the diagnostic confirmation should be done by cerebral angiography. [ABSTRACT FROM AUTHOR]

Harlequin syndrome (HS) is a rare autonomic disorder. The causes and risk factors of the disease are not fully understood. Some cases of HS are associated with traumatic injuries, tumors, or vascular impairments of the head. Symptoms of HS can also occur in some autoimmune disorders, ophthalmic disorders, sleep disorders, and with certain organic lesions. In this context, a thorough review of the pathophysiology of HS in relation to neurological, ophthalmological, and dermatological conditions is necessary. In this mini-review, we aim to review the pathophysiological changes and underlying mechanisms in primary and secondary HS. Additionally, we discuss possible management approaches for patients with HS in light of the discussed pathological mechanisms. The main symptoms of HS that are correlated with autonomic nervous system impairments include sudden unilateral flushing of the face, neck, chest, and rarely arm, with concurrent contralateral anhidrosis. Despite reported co-occurring syndromes (such as cluster headaches), several studies have shown that HS could frequently overlap with other syndromes that are disruptive to the idiopathic nerve pathways. HS usually does not require any medical treatment. In some severe cases, symptomatic treatments could be needed. However, total symptomatic relief may not be achieved in many cases of HS. We therefore suggest an approach to comprehensive management of HS, which may lead to better long-term control of HS. [ABSTRACT FROM AUTHOR]

Strabismus is defined by non-coaxial eyes. In bilateral cases, this operation can be done unilaterally or bilaterally. This study evaluated the effectiveness, results, and unilateral or bilateral strabismus surgery complications. This clinical trial was performed in 2021 in Ahwaz, Iran, on 70 patients with bilateral strabismus candidates for surgical treatments. Patients were randomly divided into two groups: patients who underwent surgery in one eye (R&R) and patients who underwent surgery in both eyes (bilateral resection). The deviation before surgery, the first day after surgery, the first week, one month, and six months after surgery were measured. The deviation reduction in the two groups was compared with each other. Also, the rate of postoperative refraction, the need for reoperation, complications of surgery (including red eyes, enophthalmos, limited eye movements, etc.), and patient satisfaction were recorded and compared. 23 patients that underwent unilateral surgery (R&R) and 47 patients that underwent bilateral surgery. The data indicated a significantly higher frequency of red-eye in 1 day and one week after the surgery in the unilateral group (P= 0.02 and P= 0.01 respectively) and substantially higher eye discharges in patients undergoing unilateral surgery (P= 0.04). We also showed that diplopia was more frequent in unilateral group 1 week, one month, and six months after surgeries (p= 0.03, P= 0.04, and P= 0.03 respectively). A significantly higher frequency of restricted eye movement was observed in the unilateral group 1 month after operations (P= 0.03). 80.8% of the bilateral surgery group and 8.7% of patients in the unilateral group were satisfied with their condition (p-value = 0.04). Performing bilateral strabismus surgery could have significantly lower minor complications compared to unilateral approach. [ABSTRACT FROM AUTHOR]

Primary plastic surgery for rehabilitation and esthetics is important for patients and their parents; however, secondary deformities of the lip and nose can occur after the primary surgery. Therefore, we performed assessment of secondary cleft lip/nasal deformities to aid in planning of surgical repair of these deformities.Materials and Methods: Forty-six patients with unilateral cleft lip, with or without cleft palate, were operated with different techniques and examined post-surgery at the Department of Maxillofacial Surgery, University of Medicine and Pharmacy Hospital and Center of Odonto-Stomatology, Hue Central Hospital. They were assessed according to Motier’s post-operative evaluation scale (1997), including the red lip, white lip, scars, and nose.Results: V notch and defect on the shift line were the most common deformities on the red lip (52.2%). About 34.8% of the patients had a short white lip on the cleft side. Straight and prominent scars were observed in 52.2% of the patients. The most common deformities of the nose were septal deviation (78.3%), followed by defects in the upper part of the nostril contour (78.3%), narrow sill (52.2%), and low position of the ala (47.8%).Conclusion: Secondary cleft lip/nasal deformities are unavoidable. It is necessary to develop a plan for surgical repair of these deformities. There is no single method of cleft lip surgery that gives perfect results. Therefore, clinicians choose a combination of methods to bring optimal results for each patient.Keywords: unilateral, cleft lip/palate, secondary deformities

Objective: To evaluate displacements and stress distributions in finite element models (FEMs) of the craniofacial complex of 13-yearold male patient with complete unilateral cleft palate (UCP), a 15-year-old female patient with complete bilateral cleft palate (BCP), and a 15-year-old female patient with isolated cleft palate (ICP), which may respond differently to expansive forces.Methods: The FEMs were based on computed tomography scans of patients with UCP, BCP, and ICP who needed maxillary expansion. Von Mises stress distribution after 0.2 mm of expansion and displacements after 5 mm of expansion were investigated.Results: The highest amount of stress was observed in the ICP model. Surprisingly, no stress was noted around the nose in the BCP model. The amount of dentoalveolar expansion decreased from anterior to posterior on the cleft side of the UCP, BCP, and ICP models. In contrast, on the non-cleft side of the UCP model, the maximum dentoalveolar expansion occurred at the molar area, decreasing toward the anterior parts. Anatomical structures expressed posterior displacement in the UCP model. In the ICP model, structures close to midline showed anterior displacement, while structures in the lateral parts showed posterior displacement. In contrast with the other 2 models, the structures in the BCP model showed anterior displacement. Vertically, all the anatomic structures in the BCP model showed inferior displacement, while in the ICP and UCP models, only the structures close to the midline showed inferior displacement.Conclusion: Maxillary expansion caused different patterns of stress distribution and displacement in different types of clefts. Clinicians should consider the type of the cleft, and may expect differing patterns of widening following maxillary expansion.

Current primary cleft nose correction techniques are associated with a significant rate of long term alar collapse. The nasal lining on the cleft side has been observed to be distorted and deficient. Nasal endoscopy was used to map the two dimensional topography of the anterior nasal airway lining in a normal and patient with unilateral cleft lip. The vestibular nasal subunit was noted to have a triple structural overlap (Lateral crus, valve and vestibule units). A nasal lining subunit based surgical strategy was designed, based on the subunit principle. The lateral crural tethering was released and differential repositioning of the cartilage/lining complex performed. The difference in domal height between the cleft and non-cleft sides was translated into a superior and medial advancement of the cartilage/lining composite subunit. The valve sub-unit defect was resurfaced with a vermilion full thickness graft, taken at the time of primary cleft lip repair. Primary septal relocation was performed and no percutaneous cartilage sutures were done. Pre and post-operative anthropometry measurements were obtained, and repeated at follow up. Complete nasal correction was seen in the unilateral cleft lip patient and was noted to be stable at 1 year follow-up. A novel nasal cartilage/lining subunit topographical map is proposed and forms the basis for a surgical strategy addressing comprehensive correction of the unilateral cleft nasal deformity.

Purpose: To report clinical outcomes in terms of disease control and toxicity in patients with major salivary gland cancers (SGCs) treated with proton beam therapy. Materials and Methods: Clinical and dosimetric characteristics of patients with SGCs treated from August 2011 to February 2020 on an observational, prospective, single-institution protocol were abstracted. Local control and overall survival were calculated by the Kaplan-Meier method. During radiation, weekly assessments of toxicity were obtained, and for patients with ≥ 90 days of follow-up, late toxicity was assessed. Results: Seventy-two patients were identified. Median age was 54 years (range, 23-87 years). Sixty-three patients (88%) received postoperative therapy, and nine patients (12%) were treated definitively. Twenty-six patients (36%) received concurrent chemotherapy. Nine patients (12%) had received prior radiation. All (99%) but one patient received unilateral treatment with a median dose of 64 GyRBE (relative biological effectiveness) (interquartile range [IQR], 60-66), and 53 patients (74%) received intensity-modulated proton therapy with either single-field or multifield optimization. The median follow-up time was 30 months. Two-year local control and overall survival rates were 96% (95% confidence interval [CI] 85%-99%) and 89% (95% CI 76%-95%], respectively. Radiation dermatitis was the predominant grade-3 toxicity (seen in 21% [n = 15] of the patients), and grade ≥ 2 mucositis was rare (14%; n = 10 patients). No late-grade ≥ 3 toxicities were reported. Conclusion: Proton beam therapy for treatment of major SGCs manifests in low rates of acute mucosal toxicity. In addition, the current data suggest a high rate of local control and minimal late toxicity.

Radiotherapy is a common treatment modality in the management of head and neck malignancies. In select clinical scenarios of well-lateralized tumors, radiotherapy can be delivered to the primary tumor or tumor bed and the ipsilateral nodal regions, while intentional irradiation of the contralateral neck is omitted. Proton beam therapy is an advanced radiotherapy modality that allows for the elimination of exit-dose through nontarget tissues such as the oral cavity. This dosimetric advantage is apt for unilateral treatments. By eliminating excess dose to midline and contralateral organs at risk and conforming dose around complex anatomy, proton beam therapy can reduce the risk of iatrogenic toxicities. Currently, there is no level I evidence comparing proton beam therapy to conventional photon radiation modalities for unilateral head and neck cancers. However, a growing body of retrospective and prospective evidence is now available describing the dosimetric and clinical advantages of proton beam therapy. Subsequently, the intent of this clinical review is to summarize the current evidence supporting the use of proton beam therapy in unilateral irradiation of head and neck cancers, including evaluation of disease site-specific evidence, unique challenging clinical scenarios, and ongoing clinical trials.

Graves' disease (GD) is an autoimmune condition that affects both thyroid gland lobes. Patients with GD with unilateral thyroid scan uptake are rare. These patients present with classic Graves' symptoms, occasionally with Graves' ophthalmopathy characteristics and increased thyroid hormones, and scintigraphic assessment reveals radiotracer uptake in only 1 lobe of the thyroid gland. In this case, a 48-year-old female presented with symptoms and signs indicative of thyrotoxicosis. Laboratory results revealed that TSH was undetectable, whereas free thyroxine and free triiodothyronine were in the high-normal range. Positive results were observed for both thyroid-stimulating Ig and TSH receptor antibodies. Ultrasonography of the thyroid gland revealed an enlarged left lobe with heterogeneous echotexture and a hyperemic gland without any focal lesions, distinct nodules, or cysts. Thyroid scintigraphy revealed enlarged and increased radioisotope uptake in the left lobe and decreased uptake in the right lobe, with no hot or cold nodules. The most likely diagnosis was unilateral GD. The patient was administered carbimazole and within 8 weeks had improved clinically and biochemically. [ABSTRACT FROM AUTHOR]

Juvenile dermatomyositis (JDM) is associated with many distinguishing features including cutaneous calcinosis, vasculitis, and ulcerated lesions. In this case, we describe an unusual presentation in a 12-year-old girl who had muscle weakness along with linear morphea over the right upper and lower extremities with overlying lichen sclerosus and calcinosis cutis. Of interest, these initial cutaneous manifestations occurred years before onset of myositis. [ABSTRACT FROM AUTHOR]

Lichen nitidus (LN) is a benign chronic eruption characterized by numerous asymptomatic papules on the body, clustered at specific sites of predilection like the dorsum of hands, abdomen, and genitalia. A 10-year-old boy presented to us with asymptomatic roughness of the left palm for 2 years. Clinical examination revealed multiple discrete pin-point papules over the left palm. Histopathological examination revealed focal lichenoid granuloma with overlying parakeratosis suggestive of LN. Hence, we are reporting this case of LN which required histopathology for confirmation due to its atypical presentation and distribution.

A congenital cataract is preventable blindness in children and is associated with intrauterine rubella infection known as congenital rubella syndrome (CRS), mostly found in developing countries. This study aims to describe the profile of unilateral cataracts in children with CRS, which are more difficult to manage than bilateral ones. As a retrospective study, we reviewed complete medical records of children with CRS and unilateral cataracts at Cipto Mangunkusumo hospital from 2017 to 2020. Fifteen patients were included, mostly male and from outside Jakarta.The mean age of onset was 2.9 months, while the average age at first presentation and surgery was 27.7 months and 29.1 months, respectively.No correlation was found between patients’ residential distance from the hospital towards duration between onset of symptoms and first presentation to the hospital. 100% and 66.7% of patients had leukocoria and microcornea as ocular manifestations. The majority of systemic manifestations are congenital heart disease.66.7% of children underwent cataract surgery without IOL implantation. Improvement of visual acuity postoperatively was observed in 13.3% of patients, and 66.7% of patients used contact lenses for visual rehabilitation. 60% of patients had posterior capsule opacity within six months of follow-up. The challenge of wearing contact lenses in children makes the risk of amblyopia even greater
