RESUMO
STUDY DESIGN: A prospective study. OBJECTIVE: To develop a simplified Chinese version of Lumbar Spine Instability Questionnaire (SC-LSIQ) and test its measurement properties. SUMMARY OF BACKGROUND DATA: The LSIQ has been translated into several languages. Different versions of LSIQ have proved good reliability and validity in evaluating patients with low back pain. However, there is no simplified Chinese version of LSIQ (SC-LSIQ). MATERIALS AND METHODS: The SC-LSIQ has been translated into a simplified Chinese version according to a standard procedure. A total of 155 patients with low back pain completed the SC-LSIQ along with Oswestry Disability Index, Roland-Morris disability questionnaire, Tampa Scale for Kinesiophobia, and visual analogue scale (VAS). The internal consistency, test-retest reliability, and validity of SC-LSIQ were then calculated to evaluate the measurement properties of SC-LSIQ. RESULTS: The results of SC-LSIQ demonstrated that there was no ceiling or floor effect detected. The Cronbach α coefficient of 0.911 determined a well internal consistency. The intraclass correlation coefficient (0.98) presented an excellent reliability of SC-LSIQ. The Pearson correlation coefficient (r) showed that the SC-LSIQ was excellent correlated to Oswestry Disability Index (r=0.809), Roland-Morris disability questionnaire (r=0.870), and Tampa Scale for Kinesiophobia (r=0.945,). Furthermore, it moderately correlated to visual analogue scale (r=0.586). CONCLUSION: The SC-LSIQ features good internal consistency, reliability, and validity for evaluating Chinese patients with LBP. Results suggest that the SC-LSIQ can be appropriately applied to patients with LBP in routine clinical practice.

Purpose: To report a patient previously treated for primary and secondary syphilis who presented with papillitis. The patient was found to have neurosyphilis likely due to inadequate treatment of primary and secondary syphilis. Observations: A 60-year-old male with human immunodeficiency virus (HIV) and hepatitis C was referred for evaluation of blurry vision for the past several months. Anterior segment examination was notable for 1+ diffuse non-granulomatous keratic precipitates and 2+ flare with trace cell in both eyes. Dilated fundus exam revealed grade 2 optic disc edema in both eyes with no evidence of infectious retinitis. He was recently treated for syphilis with a single dose of intramuscular (IM) penicillin. These findings were consistent with syphilitic papillitis likely secondary to neurosyphilis. The patient underwent a lumbar puncture which confirmed the diagnosis of neurosyphilis. He was admitted to the hospital for intravenous (IV) penicillin. He later revealed a prior history of syphilis that was treated 3 years ago and 1 year ago. Conclusions and importance: Ocular syphilis can have a wide variety of presentations. Any patient with syphilis and uveitis should have prompt work up for neurosyphilis. Patients with any stage of syphilis need close follow up with repeat titers after treatment to ensure adequate treatment and prevent progression and permanent ocular or neurologic sequelae.
RESUMO
BACKGROUND CONTEXT: Anterior controllable antedisplacement and fusion (ACAF) is a novel surgical technique for the treatment of ossification of the posterior longitudinal ligament (OPLL). Its prognostic factors for decompression have not been well studied. Additionally, no detailed radiological standard has been set for hoisting the vertebrae-OPLL complex (VOC) in ACAF. PURPOSE: To identify the possible prognostic factors for decompression outcomes after ACAF for cervical OPLL, to determine the critical value of radiological parameters for predicting good outcomes, and to establish a radiological standard for hoisting the VOC in ACAF. STUDY DESIGN: This was a retrospective multicenter study. PATIENT SAMPLE: A total of 121 consecutive patients with OPLL who underwent ACAF at a point between January 2017 and June 2018 at any one of seven facilities and were monitored for at least 1 year afterward were enrolled in a multicenter study. OUTCOME MEASURES: Japanese Orthopedic Association (JOA) scores, recovery rate (RR) of neurologic function, and surgical complications were used to determine the effectiveness of ACAF. METHODS: Patients were divided into two groups according to their RR for neurologic function. Patients with an RR of ≥50% and an RR of <50% were designated as having good and poor decompression outcomes, respectively. The relationship between various possible prognostic factors and decompression outcomes was assessed by univariate and multivariate analysis. The receiver operating characteristic curve was used to determine the optimal cutoff value of the radiological parameters for prediction of good decompression outcomes. Next, the patients were redivided into three groups according to the cutoff value of the selected radiological parameter (postoperative anteroposterior canal diameter [APD] ratio). Patients with postoperative APD ratios of ≤80.7%, 80.7%-100%, and ≥100% were defined as members of the incomplete, optimal, and excessive antedisplacement groups, respectively. Differences in decompression outcomes among the three groups were compared to verify the reliability of the postoperative APD ratio and assess the necessity of excessive antedisplacement. RESULTS: Multivariate logistic regression analysis showed that patients' age at surgery (odds ratio [OR]=1.18; 95% confidence interval [CI]=1.08-1.29; p<.01) and postoperative APD ratio (OR=0.83; 95% CI=0.77-0.90; p<.01) were independently associated with decompression outcomes. The optimal cutoff point of the postoperative APD ratio was calculated at 80.7%, with 86.2% sensitivity and 73.5% specificity. There were no significant differences in the postoperative JOA scores and RRs between the excessive antedisplacement group and optimal antedisplacement group (p>.05). However, a lower incidence of cerebrospinal fluid leakage and screw slippage was observed in the optimal antedisplacement group (p<.05). CONCLUSIONS: Patients' age at surgery and their postoperative APD ratio are the two prognostic factors of decompression outcomes after ACAF. The postoperative APD ratio is also the most accurate radiological parameter for predicting good outcomes. Our findings suggest that it is essential for neurologic recovery to restore the spinal canal to more than 80.7% of its original size (postoperative APD ratio >80.7%), and restoration to less than its original size (postoperative APD ratio <100%) will help reduce the incidence of surgical complications. This may serve as a valuable reference for establishment of a radiological standard for hoisting the VOC in ACAF.

BACKGROUND: Novel coronavirus disease 2019 (COVID-19) was first found in Wuhan, China, and it has rapidly spread worldwide since the end of 2019. There is an urgent need to treat the physical and psychological aspects of COVID-19. Interpersonal psychotherapy (IPT)-based psychological intervention is an evidence-based therapy for depression and post-traumatic stress disorder. CASE SUMMARY: This report describes a case of COVID-19 in a patient who transmitted the disease to his entire family. The patient received four sessions of IPT-based psychological intervention. We used the Hamilton Rating Scale for Depression and Patient Health Questionnaire to measure depression level, and the Hamilton Anxiety Scale and Generalized Anxiety Disorder to measure anxiety among the patients. CONCLUSION: This case shows that IPT-based therapy can reduce COVID-19 patient depression and anxiety and the advantage of IPT-based therapy.
RESUMO
At the end of 2019, a new form of pneumonia disease known as the corona virus disease 2019 (COVID-19) rapidly spread throughout most provinces of China, and the total global number of COVID-19 cases has surpassed 500 000 by Mar. 27, 2020 (WHO, 2020). On Jan. 30, 2020, the World Health Organization (WHO) declared COVID-19 a global health emergency (WHO, 2020). COVID-19 causes most damage to the respiratory system, leading to pneumonia or breathing difficulties. The confirmed case fatality risk (cCFR) was estimated to be 5% to 8% (Jung et al., 2020). Besides physical pain, COVID-19 also induces psychological distress, with depression, anxiety, and stress affecting the general population, quarantined population, medical staff, and patients at different levels (Kang et al., 2020; Xiang et al., 2020). Previous research on patients in isolation wards highlighted the risk of depressed mood, fear, loneliness, frustration, excessive worries, and insomnia (Abad et al., 2010).

Larvae of a previously unknown species of gall midge were found causing large numbers of pustulate leaf galls on Peking lilac, Syringa reticulata subsp. pekinensis (Oleaceae), in parklands and street greenery in Beijing, China. Heavily galled leaves become senescent and fall off prematurely. The gall midge is named Pekinomyia syringae Jiao Kolesik, its morphology is described and the COI mitochondrial gene and 12S ribosomal gene segments are sequenced. A new genus, Pekinomyia Jiao Kolesik (Cecidomyiinae: Lasiopteridi), is erected for the new species. The new genus differs from other Lasiopteridi in the strongly sclerotized aedeagus and the lack of mesobasal lobes in the male terminalia and is not assigned to any known tribe.

STUDY DESIGN: A retrospective study of 257 normal children at a single center from July 2016 to November 2018 was performed. OBJECTIVE: To evaluate the spinopelvic parameters in a population of normal children and adolescents in mainland China. SUMMARY OF BACKGROUND DATA: Values for sagittal parameters of the spine vary significantly by ages and different population. No study has yet quantified the normal measures for children and adolescents in China, or how these measures compare with other populations. METHODS: Pelvic incidence (PI), sacral slope, pelvic tilt, thoracic kyphosis (TK, T5-T12), lumbar lordosis (LL, L1-S1), and sagittal vertical axis were measured and evaluated by whole spine AP&lateral X-ray images. RESULTS: A total of 257 subjects, including 116 boys (45%) and 141 girls (55%) aged 3 to 12 years, were enrolled. Correlation matrix analysis demonstrated that sagittal balance is strongly correlated with age and Risser sign, including PI, a reported fixed parameter. Further investigation showed that PI could be expressed by the equation PIâ=â26.243+1.153×age. CONCLUSION: PI was not a fixed but a dynamic parameter in the population under 12-year old. Indeed, PI increases with age and bone maturity in childhood. We also found lower PI, pelvic tilt, and sacral slope compared with published studies of adolescents in other countries. These results may aid in the treatment of patients with spinal deformity, to help them achieve a certain degree of sagittal spinopelvic balance. LEVEL OF EVIDENCE: 2.

BACKGROUND: Spinal fusion is considered the gold standard procedure for treating spinal degeneration, tumors, and trauma. An inflammatory response is an important part of bone repair. We investigated the polarization change of inflammatory macrophages (M1) and resident macrophages (M2) during low-intensity pulsed ultrasound (LIPUS) treatment. METHODS: Thirty male Sprague Dawley rats (age: 12 weeks; weight: 300â¯g) were used in the study. A rat spinal fusion model was established by surgical procedures. LIPUS treatment (20â¯min.â¯d, 5 d/wk) was begun 3 days after surgery. The rats were randomly divided into a control group (5 subgroups, 3 rats in each subgroup) and LIPUS group (5 subgroups, 3 rats in each subgroup), and sacrificed on day 3, 5, 7, 10, and 14 after spinal fusion surgery for further evaluation. Bone volume was measured by micro-CT, fusion region was examined by histological analyses, types of macrophages in the fusion area were examined by immunohistochemical staining. Raw264.7 cells and bone marrow-derived macrophages (BMDM) were used in cell experiments. Cells were divided into a control group and LIPUS group. Flow cytometry was used to examine the rate of resident macrophages, and real-time PCR was used to examine the mRNA expression of anti-inflammation genes. RESULTS: LIPUS promoted spinal fusion and stimulated the transition of F4-80+/Mac-2+ (M1) to F4-80+/Mac-2- (M2), leading to the early appearance of resident macrophages. Cell experiments showed CD206+ macrophages (M2) were significantly increased after LIPUS treatment. M2-related genes and anti-inflammation factors (Arg-1, PPAR-γ, and IL-4) were increased after LIPUS treatment. CONCLUSION: The earlier transition from inflammatory to resident macrophage might be one reason for the positive effect of LIPUS on spinal fusion.

Gram-positive bacteria remain the leading cause of endophthalmitis, a blinding infectious disease of the eye. Murine models have been widely used for understanding the pathogenesis of bacterial endophthalmitis. In this study, we sought to develop an alternative zebrafish (Danio rerio) model for Staphylococcus aureus and compare the disease pathobiology to a murine model. Endophthalmitis was induced in zebrafish and C57BL/6 mice through the intravitreal injection of S. aureus. Disease progression was monitored by assessing corneal haze, opacity, bacterial burden, and retinal histology. Our results demonstrated that, unlike the murine models, zebrafish maintained ocular integrity, corneal transparency, and retinal architecture. We found that the zebrafish was capable of clearing S. aureus from the eye via transport through retinal vessels and the optic nerve and by mounting a monocyte/macrophage response beginning at 8 hour post-infection (hpi). The bacterial burden increased up to 8 hpi and significantly decreased thereafter. An assessment of the innate retinal response revealed the induced expression of Il-1ß and Il-6 transcripts. Collectively, our study shows that unlike the murine model, zebrafish do not develop endophthalmitis and rapidly clear the pathogen. Hence, a better understanding of the zebrafish protective ocular innate response may provide new insights into the pathobiology of bacterial endophthalmitis.
RESUMO
PURPOSE: To report the intraoperative optical coherence tomography (OCT)-guided surgery of a consolidated sub-internal limiting membrane (ILM) hemorrhage that developed into a sub-ILM fibrotic membrane in a child with a history of Terson syndrome. OBSERVATIONS: A one year-old boy with a history of Terson syndrome due to a motor vehicle accident presented three months after trauma with a white feather-shaped membrane in the left macula. Preoperative OCT showed a preretinal hyperreflective tissue at the foveal center. The patient underwent pars plana vitrectomy. After separation of the posterior hyaloid, intraoperative OCT did not show any change in structural components. After peeling the ILM, the fibrotic membrane persisted. A bent 30-gauged needle was used to create a plane of dissection in the adherent sub-ILM membrane, which was then peeled with ILM forceps without complication. Post-operative OCT confirmed complete excision without evidence of macular edema. Pathology results indicated presence of fibrocellular tissue that contained hemosiderin, consistent with old organized hemorrhage as a component of the membrane. CONCLUSION AND IMPORTANCE: Sub-ILM hemorrhage may persist as a tautly adherent fibrotic membrane that can mimic the appearance of an epiretinal membrane or a chronic subhyaloidal hemorrhage during examination, especially in young children. Intraoperative OCT may aid in select complex macular surgery cases to better delineate the planes of dissection during sub-ILM fibrosis excision.
RESUMO
The histologic findings of a subretinal band and epiretinal membrane (ERM) excised from two patients who developed retinal detachments (RDs) after non-U.S. Food and Drug Administration-regulated intravitreal "stem cell" injections are reported. Both membranes were composed of fibrocellular tissue that stained positively with Smooth Muscle Actin and Masson's trichrome, consistent with collagenous and smooth muscle composition. CD34 immunostain (for hematopoietic cells) was negative for the subretinal band and minimally positive for the ERM. The authors speculate that the "stem cells" may cause RDs by differentiation into myofibroblasts that cause tractional membranes, though further studies are warranted.

STUDY DESIGN: A prospective study. OBJECTIVE: The aim of this study was to develop and assess the internal reliability and structure validity of a simplified Chinese version of the Neck Bournemouth Questionnaire (SC-NBQ) for evaluation of patients with nonspecific neck pain (NP) in mainland China. SUMMARY OF BACKGROUND DATA: The NBQ has been cross-culturally translated into several languages with good internal consistency and construct validity to evaluate low back pain and NP. However, the NBQ has been not translated or validated for Chinese-speaking patients. METHODS: The SC-NBQ was developed by standard cross-translation procedures, and completed by 106 patients with nonspecific NP, along with other self-reported questionnaires, including the Neck Disability Index (NDI), Hospital Anxiety and Depression Scale (HADS), Functional Rating Index (FRI), and 36-Item Short Form Health Survey (SF-36). The internal consistency, test-retest reliability, and construct validity of the SC-NBQ were determined. RESULTS: The NBQ was successfully translated into Chinese. All patients completed the SC-NBQ twice, and the other instruments. Score distribution demonstrated that there was no floor or ceiling effects of the SC-NBQ. Cronbach α coefficient (αâ=â0.89) and intraclass correlation coefficient (ICCâ=â0.97) showed good internal consistency and test-retest reliability. A good construct validity was shown by strong correlation with HADS (râ=â0.75), NDI (râ=â0.82), FRI (râ=â0.90) and SF-36 physical functioning (râ=â0.75), and bodily pain (râ=â0.75) subscales. CONCLUSION: The SC-NBQ demonstrated good internal consistency, test-retest reliability, and construct validity, and may be used for the evaluation of NP in Chinese-speaking patients. LEVEL OF EVIDENCE: 2.

CONTEXT.: The pathogenesis of primary ocular adnexal marginal zone lymphoma (POAMZL) remains unclear. The reported associations with Chlamydia psittaci infection and MYD88 mutations are highly variable. OBJECTIVE.: To examine MYD88 L265P mutation in ocular marginal zone lymphomas and correlate with clinicopathologic features and Chlamydia infection. DESIGN.: Presence of MYD88 L265P mutation and Chlamydia infection in lymphoma was analyzed by using sensitive polymerase chain reaction (PCR) methods. RESULTS.: The MYD88 L265P mutation was identified in 8 of 22 POAMZLs (36%), including 2 of 3 cases in which PCR failed to detect clonal IGH gene rearrangement; none of the 4 secondary marginal zone lymphomas were positive. Test results for Chlamydia were negative in all cases. Patients with and without the MYD88 mutation had similar clinicopathologic features. CONCLUSIONS.: The MYD88 mutational analysis provides important information in diagnostic workup of POAMZL. The frequent MYD88 mutation suggests a critical role of this aberration in the pathogenesis of POAMZL and may serve as a therapeutic target for patients with progressive disease.

A 73-year-old woman with 2 weeks of progressive painless vision loss was found to have bilateral corneal edema, jaw claudication, and temporal headache. Multimodal imaging revealed an Amalric choroidal infarct in the left eye visualized by widefield indocyanine green angiography and swept-source optical coherence tomography angiography (SS-OCTA). Prompt intravenous corticosteroid treatment resulted in 20/20 vision, and giant cell arteritis (GCA) was confirmed by a temporal artery biopsy. The case underscores the use of widefield SS-OCTA as a non-invasive test to aid in the diagnosis of GCA, as well as bilateral cornea edema as a rare presentation of GCA.

PURPOSE: To investigate the frequency of conjunctival erosions in a series of patients who underwent Ahmed valve implantation in a tertiary referral center and to study risk factors associated with the conjunctival erosions. METHODS: This is a single-center, retrospective case-control study of all patients who underwent Ahmed valve implantation between October 2006 and July 2016 at the Kresge Eye Institute in Detroit, Michigan. The series consisted of 306 eyes (277 patients) that underwent Ahmed valve implantation. The rate of conjunctival erosions was determined. Univariate, bivariate, and Cox-proportional hazard analyses were performed to identify factors associated with conjunctival erosions. RESULTS: During the study period, 23 erosions occurred in 306 eyes (7.52%). Aphakia was significantly more common in eyes with erosions (P < 0.05). Aphakia (P = 0.02), uveitic glaucoma (P = 0.03), and longer post-operative use of topical steroids (P < 0.04) significantly increased the risk of erosions based on the Cox model. There were similar rates of erosions with each type of patch graft. No conjunctival erosion was observed after using the modified scleral tunnel method (n = 10). CONCLUSIONS: The overall erosion rate was 7.52% in our series. Uveitic glaucoma, aphakia, and longer post-operative use of topical steroids were significantly associated with conjunctival erosions.
RESUMO
A 16-year-old male presented with blurred vision in the right eye after recent travel to Nicaragua. Funduscopic examination revealed subretinal cysticercosis superior to the optic nerve. The cyst was drained and excised using a bimanual, three-dimensional, heads-up-assisted pars plana vitrectomy without complications. Technical maneuvers for cyst extraction along with clinicopathological correlation are described. Postoperatively, the patient exhibits no signs of recurrence and has excellent vision.

BACKGROUND: Osteoarthritis (OA) is a common degeneration disease characterized with joint pain. The aim of the present study was to systemically review the effects of LIPUS on pain relief and functional recovery in patients with knee osteoarthritis (OA). METHODS: PubMed, Embase, and Cochrane Library were searched manually for researches on LIPUS treatment in patients with knee OA from 1945 to July 2017. Two investigators independently selected the studies according to the inclusion and exclusion criteria, extracted the concerned data, and assessed the included studies. Meta-analysis was performed to evaluate VAS, WOMAC, and ambulation speed between control and LIPUS groups. RESULTS: Five studies were selected in this study. Compared with control group, LIPUS group received a decrease of pain intensity with moderate heterogeneity (-0.79, 95% CI, -1.57 to 0.00; I2 = 65%, P = 0.04) by VAS and improvement in knee function by WOMAC (-5.30, 95% CI, -2.88 to -7.71; I2 = 44%, P = 0.17). No significant improvement was found in ambulation speed (0.08 m/s, 95% CI, -0.02 to 0.18 m/s; I2 = 68%, P = 0.03). CONCLUSION: The present study includes 5 high quality randomized controlled trials. The result indicated that LIPUS, used to treat knee OA without any adverse effect, had a beneficial effect on pain relief and knee functional recovery. More evidence is needed to prove whether LIPUS is effective in improving walking ability.
