RESUMO
BACKGROUND: Primary spontaneous pneumothorax occurs in otherwise healthy young patients. Optimal management is not defined and often results in prolonged hospitalisation. Data on efficacy of ambulatory options are poor. We aimed to describe the duration of hospitalisation and safety of ambulatory management compared with standard care. METHODS: In this open-label, randomised controlled trial, adults (aged 16-55 years) with symptomatic primary spontaneous pneumothorax were recruited from 24 UK hospitals during a period of 3 years. Patients were randomly assigned (1:1) to treatment with either an ambulatory device or standard guideline-based management (aspiration, standard chest tube insertion, or both). The primary outcome was total length of hospital stay including re-admission up to 30 days after randomisation. Patients with available data were included in the primary analysis and all assigned patients were included in the safety analysis. The trial was prospectively registered with the International Standard Randomised Clinical Trials Number, ISRCTN79151659. FINDINGS: Of 776 patients screened between July, 2015, and March, 2019, 236 (30%) were randomly assigned to ambulatory care (n=117) and standard care (n=119). At day 30, the median hospitalisation was significantly shorter in the 114 patients with available data who received ambulatory treatment (0 days [IQR 0-3]) than in the 113 with available data who received standard care (4 days [IQR 0-8]; p<0·0001; median difference 2 days [95% CI 1-3]). 110 (47%) of 236 patients had adverse events, including 64 (55%) of 117 patients in the ambulatory care arm and 46 (39%) of 119 in the standard care arm. All 14 serious adverse events occurred in patients who received ambulatory care, eight (57%) of which were related to the intervention, including an enlarging pneumothorax, asymptomatic pulmonary oedema, and the device malfunctioning, leaking, or dislodging. INTERPRETATION: Ambulatory management of primary spontaneous pneumothorax significantly reduced the duration of hospitalisation including re-admissions in the first 30 days, but at the expense of increased adverse events. This data suggests that primary spontaneous pneumothorax can be managed for outpatients, using ambulatory devices in those who require intervention.

OBJECTIVES: The Coronavirus disease 2019 (COVID-19) pandemic is straining healthcare resources. Molecular testing turnaround time precludes having results at the point-of-care (POC) thereby exposing COVID-19/Non-COVID-19 patients while awaiting diagnosis. We evaluated the utility of a triage strategy including FebriDx, a 10-minute POC finger-stick blood test that differentiates viral from bacterial acute respiratory infection through detection of Myxovirus-resistance protein A (MxA) and C-reactive protein (CRP), to rapidly isolate viral cases requiring confirmatory testing. METHODS: This observational, prospective, single-center study enrolled patients presenting to/within an acute care hospital in England with suspected COVID-19 between March and April 2020. Immunocompetent patients ≥16 years requiring hospitalisation with pneumonia or acute respiratory distress syndrome or influenza-like illness (fever and ≥1 respiratory symptom within 7 days of enrolment, or inpatients with new respiratory symptoms, fever of unknown cause or pre-existing respiratory condition worsening). The primary endpoint was diagnostic performance of FebriDx to identify COVID-19 as a viral infection; secondary endpoint was SARS-CoV-2 molecular test diagnostic performance compared with the reference standard COVID-19 Case Definition (molecular or antibody detection of SARS-CoV-2). RESULTS: Valid results were available for 47 patients. By reference standard, 35 had viral infections (34/35 COVID-19; 1/35 non-COVID-19; overall FebriDx viral sensitivity 97.1% (95%CI 83.3-99.9)). Of the COVID-19 cases, 34/34 were FebriDx viral positive (sensitivity 100%; 95%CI 87.4-100); 29/34 had an initial SARS-CoV-2 positive molecular test (sensitivity 85.3%; 95%CI 68.2-94.5). FebriDx was viral negative when the diagnosis was not COVID-19 and SARS-Cov-2 molecular test was negative (negative predictive value (NPV) 100% (13/13; 95%CI 71.7-100)) exceeding initial SARS-CoV-2 molecular test NPV 72.2% (13/19; 95%CI 46.4-89.3). The diagnostic specificity of FebriDx and initial SARS-CoV-2 molecular test was 100% (13/13; 95%CI 70-100 and 13/13; 95%CI 85.4-100, respectively). CONCLUSIONS: FebriDx could be deployed as part of a reliable triage strategy for identifying symptomatic cases as possible COVID-19 in the pandemic.

To review the susceptibility of bacterial isolates to ceftazidime and vancomycin isolated from patients with endophthalmitis. Microbiology records of patients with endophthalmitis between June 2010 and May 2013 were reviewed. Vitreous and AC fluids obtained from patients with endophthalmitis were subjected to direct microscopy examination and culture. Antibiotic susceptibility of the isolates was performed by Kirby Bauer disk diffusion method. Resistant to ceftazidime in Gram negative bacteria (GNB) by disk diffusion method is confirmed by minimum inhibitory concentration using E test. Culture was positive for bacteria/Fungi in 224/356 patients (62.9 %). Out of 224 patients, 191 (85.2 %) patients showed bacterial growth and 33 (14.0 %) showed fungal growth. Mixed bacterial infection was seen in five patients. Among the GNB, 23/123 (18 %) of the isolates were resistant to ceftazidime, and all the Gram positive bacteria 73/73 (100 %) were susceptible to vancomycin. Sixteen of 123 (13 %) GNB were resistant to amikacin. Although there is an increase in resistance to ceftazidime compared to amikacin in GNB, amikacin intravitreal injection is associated with macular toxicity and no single antibiotic has full coverage for all GNB. Combination of vancomycin and ceftazidime empiric therapy can be continued in patients with suspected endophthalmitis and treatment is modified based on clinical response and susceptibility results.

BACKGROUND: UK clinical guidance for lung cancer (NICE 141) includes pathways for chest X-rays (CXRs). Many patients fulfilling the criteria do not receive one, either because they do not consult their doctor or because their doctor does not refer them. The town of Corby, UK, has particularly high incidence and mortality rates for lung cancer and was chosen as a pilot site for a new, patient-requested X-ray service. METHODS: The number of community-initiated CXRs were compared before and after the introduction of the service and between similar geographical areas. Clinical data and patient questionnaires were analysed for those attending the service. RESULTS: There was a 63% increase in the total number of community-initiated CXRs in Corby for the year following the introduction of the service, compared with the year before. This was statistically greater than in surrounding geographical areas. Corby General Practitioners also requested 47% more CXRs than in the previous year. CONCLUSIONS: The implementation of the service was associated with a significant increase in the numbers of clinically indicated CXRs in an area of high lung cancer incidence and mortality. The service attracted a clinically appropriate population. The numbers of cancers detected were in line with statistical expectations.

INTRODUCTION: Haemoptysis can be a feature of lung cancer and patients are typically fast-tracked for evaluation with chest radiography, contrast-enhanced CT and fibreoptic bronchoscopy (FOB). OBJECTIVE: We aim to explore whether FOB should be conducted as a component of the routine evaluation of non-massive haemoptysis, especially in the context of suspected lung cancer. METHODS: MEDLINE, EMBASE and Cochrane Library were searched for studies comparing FOB with CT in the evaluation of non-massive haemoptysis while reporting at least one of the listed primary outcomes. Primary outcomes include sensitivity of diagnostic modality with respect to lung cancer. Secondary outcomes include detection of other aetiologies such as infection. Results were synthesised using a random effects meta-analysis. Sensitivity analysis was performed for patient age group and year of study. Risk of bias assessment was carried out with the Quality Assessment of Diagnostic Accuracy Studies-2 tool. RESULTS: A total of 2273 citations were screened and 11 studies were included, comprising a total sample size of 2015 patients with 226 confirmed cases of lung cancer. A total of 1816 and 1734 patients received a CT scan and FOB, respectively. The pooled sensitivities for detection of lung cancer using CT scan and bronchoscopy were 98% (95% CI 93.0% to 99.0%) and 86% (95% CI 63.0% to 95.0%), respectively. The sensitivity of CT was higher than that of FOB for both primary and secondary outcomes. CONCLUSION: This study suggests that bronchoscopy does not offer significant additional diagnostic benefit in the evaluation of patients presenting with non-massive haemoptysis and a negative CT scan.

BACKGROUND: Ultrasound (US) guidance is widely used for needle positioning for cervical medial branch blocks (CMBB) and radiofrequency ablation, however, limited research is available comparing different approaches. OBJECTIVE: We aimed to assess the accuracy and safety of 3 different US-guided approaches for CMBB. STUDY DESIGN: A cadaveric study divided into ultrasound-guided needle placement and fluoroscopy evaluation stages. SETTING: Department of Pathology, Forensic, and Insurance Medicine, Semmelweis University. METHODS: Sonographically guided third occipital nerve (TON), C3, C4, C5 and C6 medial branch injections and radiology evaluations were performed.The 3 approaches compared were:1. ES (published by Eichenberger-Siegenthaler): US probe in the coronal plane to visualize the cervical articular pillars, needle approach out of the plane, from anterior to posterior.2. Fi (published by Finlayson): US probe in the transverse plane to visualize a cervical articular pillar and its lamina, needle approach in the plane, from posterior to anterior.3. FiM (Modified Finlayson approach): Needles are placed as in Fi, but then adjusted with a coronal view of the cervical articular pillars.Fluoroscopy images were taken and later evaluated, for "crude", "high precision" and "dangerous" placement. RESULTS: One hundred and fifty-five needle placements were assessed (10 were excluded, as no anterior-posterior fluoroscopy images were saved). Interobserver agreement on position of needle placement between the 5 observers was very high; the Fleiss' Kappa was 0.921. For crude placement, no significant differences were identified between various approaches; (77.6%, 79.5%, and 75.6% for the ES, Fi, and FiM respectively). However, for placement in predefined high-precision zones, ES resulted in significantly more success (ES: 42.9%, Fi: 22.7%, and FiM: 24.4%, P = 0.032). Fi and FiM resulted in no dangerous placements, while ES led to the potential compromise of the exiting nerve root and vertebral artery on three occasions. In 10% of the placements, the levels were identified wrongly, with no difference between the various approaches. LIMITATIONS: Feedback from a live patient, may prevent some existing nerve root injections, unlike in a cadaver. Though a higher number of needles were placed in this study than in most available publications, the number is still low at each individual medial branch level. CONCLUSION: Fi proved safer than ES. Fi was equally successful in targeting the articular pillar, however, ES proved the most successful in placing the needle in the center of the articular pillar. Adding another, (coronal) US view to check needle position in FiM did not improve safety or precision. Identifying CMB levels with the US is challenging with all approaches, therefore we still recommend using fluoroscopy for level identification. While there were pros and cons with either procedure, the efficacy findings of previous papers were not replicated on elderly cadavers with arthritic necks.

INTRODUCTION: Myofascial pain dysfunction syndrome (MPDS) is a disorder which is characterized by facial pain and limited mandibular function because of the complex nature of this disease. Malocclusion was never evaluated in MPDS patients to know its role. Electromyographic silent period durations of masseter were used for objective assessment of MPDS patients. AIM: To evaluation of role of malocclusion in MPDS patients and also to study the EMG masseteric silent period pattern in MPDS patients in different malocclusions. MATERIALS AND METHODS: Two groups, groups I and II of 75 subjects each, were included in this study. Groups I and II constituted the normal subjects and MPDS patients respectively. All these subjects in both the groups were again subdivided based on Angle's class I, II and III malocclusion. Electromyographic (EMG) silent period of masseteric muscle on both sides was measured for all the subjects in both the groups to know whether it differs according to the type of malocclusion. RESULTS: The silent period was more in group II (MPDS patients). There was no signifcant difference in the silent periods in Angle's class I, II and III malocclusion in group I, whereas in group II, there was a signifcant difference in the silent period in Angle's class II compared to Angle's class I and III. There was no signifcant difference between males and females. CONCLUSION: MPDS patients are more in Angle's class I malocclusion. Silent period is more in Angle's class II malocclusion of MPDS group. CLINICAL SIGNIFCANCE: The EMG masseter silent period duration can be advantageously utilized as an adjunct to clinical examination for diagnosis of myofascial pain dysfunction syndrome. It is enough if one side masseter muscle is measured for silent period duration.

PURPOSE: To report a case of multiple evanescent white dot syndrome (MEWDS) following adenovirus vector-based Coronavirus disease 2019 (COVID-19) vaccine, Covishield and to present a summary of previously reported cases of MEWDS following COVID-19 vaccines. METHODS: Retrospective case report and review of literature. RESULTS: A 22-year-old Indian female presented with blurred vision, scotomata, and photopsias in her left eye, a day after administration of second dose of Covishield vaccine. Her clinical findings and imaging features confirmed the diagnosis of MEWDS. Her symptoms resolved spontaneously after 2 weeks. CONCLUSION: This is the first reported case of MEWDS following an adenovirus vector-based COVID-19 vaccine. Comparison with previously reported cases of MEWDS following COVID-19 vaccination showed that patients are generally healthy, young to middle-aged women, who develop symptoms after a median time of one week and recover spontaneously over a median period of 4 weeks.

Hyperekplexia (HK) or startle disease is an uncommon, early infantile onset, potentially treatable neurogenetic disorder. It is characterized by an exaggerated startle reflex in response to tactile or acoustic or visual stimuli followed by generalized hypertonia. It is caused by genetic mutations in a number of different genes such as GLRA1, SLC6A5, GLRB, GPHN, and ARHGEF9. HK is frequently misdiagnosed as a form of epilepsy and is advised for prolonged antiseizure medications. Here, we report a two-month-old female child with HK, who was treated for epilepsy. Next-generation sequencing revealed a pathogenic homozygous missense mutation of variant c.1259C>A in exon 9 of the GLRA1 gene that was compatible with the diagnosis of hyperekplexia-1.
RESUMO
Purpose: To evaluate the impact of the inverted internal limiting membrane (ILM)-flap technique on the visual outcome and anatomical recovery for small (<250 µ), medium (<400 µ), and large (>400 µ) macular holes (MHs). Methods: Retrospective study included consecutive idiopathic MH cases operated on using the inverted ILM-flap technique. Clinical data were retrieved from electronic medical records (EMRs), surgical videos, and optical coherence tomography (OCT) machines. Eyes with axial length >25 mm, coexisting macular diseases, and follow-up <6 weeks were excluded. Data included the presence or absence of ILM flap and restoration of External Limiting Membrane (ELM), Ellipsoid Zone (EZ) lines. Mean visual improvement and structural recovery were compared between eyes showing ILM flap and those showing no flap in three MH size groups. Results: Forty eyes of 38 patients with a mean age of 62.7 ± 10.1 years and a mean MH diameter of 348 ± 152 µm were included. The mean follow-up was 527 ± 478 days with anatomical closure observed in all eyes. Mean best-corrected visual acuity (BCVA) improved significantly from 0.87 ± 0.38 to 0.35 ± 0.26. ILM flap was visible in 29 (72.5%) all MHs, 7 (53.8%) small MHs (n = 13), 8 (61.5%) medium MHs (n = 13), and 14 (100%) large MHs (n = 14). The mean BCVA change was 0.47 ± 0.34, 0.53 ± 0.48, and 0.56 ± 0.20 in large, medium, and small MHs, respectively, and the difference between eyes showing ILM flap versus no flap in each MH size group was not statistically significant (P > 0.05). However, for medium MHs, it was higher in the ILM flap (0.66 ± 0.52) group compared to the no flap (0.32 ± 0.37) group. One eye with small MH developed significant gliosis resulting in reduced BCVA. ELM was restored in all eyes with small and medium MHs. Conclusion: We observed that the ILM flap did not adversely affect anatomical and visual outcomes for MHs <400 µm. Restoration of ELM suggests minimal interference in structural recovery by an ILM flap.

'Stage shift' has been proposed as a marker of impact of Coronavirus 2019 (COVID-19) in lung cancer services; however, there are no data available specifically from income-deprived areas. Thus, this study evaluated the impact of the COVID-19 pandemic on lung cancer care in our area (Corby; among the most income deprived in England) and identified focus recovery areas. The study was a retrospective observational study of 668 consecutive patients with lung cancer at a district general hospital, pre-, during and after the COVID peak. Outcomes were the overall number of cases, presenting staging and treatment pathway. Overall, 32 fewer patients were diagnosed during the pandemic, with more inpatient diagnoses (p=0.01) and fewer primary care referrals (p<0.0001). There were no differences observed in treatment intent or 'stage shift'. Our results suggest that COVID-19 negatively affected the whole lung cancer pathway in our area. However, 'stage shift' might not be ideal to assess the impact of COVID-19 in income-deprived areas. Further studies will help the strategic rollout of a screening programme to identify patients with lung cancer earlier on in such areas.

This study aims to compare the safety and efficacy of clopidogrel and ticagrelor in patients with acute coronary syndrome (ACS) and undergoing dialysis. This study was conducted per the guidelines of the Preferred Reporting of Systematic Reviews and Meta-Analyses (PRISMA). A comprehensive search was performed using electronic databases, including PubMed, EMBASE, and Web of Science, to identify relevant studies comparing clopidogrel and ticagrelor in patients undergoing dialysis. To ensure the inclusion of all relevant articles, a combination of the following keywords, along with medical subject heading (MeSH) terms, was used: "clopidogrel," "ticagrelor," "acute coronary syndrome," and "dialysis." The primary endpoint of this meta-analysis was the incidence of major adverse cardiovascular events (MACE), which consisted of cardiovascular death, myocardial infarction, stroke, and revascularization. The secondary endpoint was all-cause mortality. The occurrence of any bleeding events (including major and nonmajor bleeding events) and major bleeding events was chosen as the safety endpoints. A total of four studies were included in the pooled analysis. The pooled sample size was 5,417 patients, including 892 in the ticagrelor group and 4525 in the clopidogrel group. The findings indicate that ticagrelor, compared to clopidogrel, is associated with a significantly higher risk of MACEs, all-cause death, and major bleeding events. The findings suggest that clopidogrel may be a better choice for individuals with ACS undergoing dialysis due to its lower risk of MACE, all-cause death, and major bleeding events compared to ticagrelor.
RESUMO
A woman in her 70s who was being followed up for neovascular age-related macular degeneration (nAMD) in both eyes for 2 years with recalcitrant choroidal neovascularisation (CNV) and had an episode of acute endophthalmitis in one eye was identified. After treatment of postinjection culture-negative right eye (RE) endophthalmitis with intravitreal vancomycin and tazobactam, the patient had complete regression of treatment-resistant CNV in RE to date with postinfection follow-up of 2 years. In contrast, the fellow eye continued showing activity in the choroidal neovascular membrane that required antivascular endothelial growth factor injections on a pro re nata basis to date. Prolonged regression of nAMD for 3 years in the affected eye and continued activity in the fellow eye support the hypothesis that inflammation accompanying endophthalmitis or the drugs used for the treatment can have a role in the regression of nAMD.

A 65-year-old male with proliferative diabetic retinopathy (PDR) and non-clearing vitreous hemorrhage underwent 25G pars plana vitrectomy (PPV). A large disk of thick organized blood of 5 disk diameter (DD) size was encountered in subhyaloid space. All attempts including lower cut rates to remove this disk using a 25G cutter turned futile. We used a 20G fragmatome to safely remove this hard clot from vitreous cavity in 50 s. Surgical time for removal of similar clot of 3 DD by 25G cutter in another eye was 5 min. Removal of thick clotted subhyaloid blood by ultrasonic fragmentation during diabetic vitrectomy is a safe, faster, and useful maneuver.

To describe a simple and novel technique that overcomes the limitation of smartphone-based fundus photography and allows examiners to capture peripheral retinal images with indentation. Smartphone with video camera in flash-on mode was mounted on virtual-reality (VR) headset. This was combined with +28D lens and +20D lens and soft cotton bud to capture high-quality videos of peripheral fundus with indentation. Autofocus function of the camera and examiner's head movements to adjust the distance was used to obtain retinal video. The procedure is akin to indirect ophthalmoscopy. The feasibility of obtaining well-focused retinal images during indentation was checked. We could obtain good quality videos demonstrating indentation of the peripheral fundus in 10 eyes showing different pathologies such as laser marks, lattice degeneration, and pigmented lesions. VR headset-mounted smartphone-based indentation fundus videography is an innovative cost-effective technique to capture peripheral retinal images. The technique can be useful for documenting retinopathy of prematurity lesions and other situations where widefield photography is not possible.
RESUMO
Background This study aims to examine the clinico-etiological profile of children with the first episode of a seizure and categorize seizure types based on age groups in a tertiary care hospital. Methodology This was a prospective observational study conducted at a tertiary care medical institute in India over two years. Children (one month to 12 years of age) with the first episode of a seizure were included in the study population. The data collected included demographic profile, history, examination, biochemical profile, electroencephalogram (EEG), and neuroimaging. Children were categorized as generalized-onset, focal-onset, and unknown-onset seizures based on the International League Against Epilepsy 2017 seizure classification. Children were also classified according to specific etiologies such as structural, metabolic, or other specific causes. All the children were followed up at the hospital's outpatient clinic or through a telephonic interview. Results A total of 220 children were examined in this study. Among them, 64% were male and 36% were female, with a male-to-female ratio of 1.75:1. Among the 220 children, 21.8% had a family history of seizure. The most common type of seizures were generalized-onset seizures (n = 110, 50%), followed by focal-onset seizures (n = 96, 43.6%). Overall, 9% of children presented with status epilepticus as their first-episode seizure. An abnormal EEG was recorded for 122 (76%) children. While 60% of children had abnormal neuroimaging findings, the remaining had normal neuroimaging. Febrile seizures (n = 92, 41.9%) were the most common cause of the first episode of a seizure. Most of the febrile seizures occurred between the age of one and four (n = 60, 65.2%). Epilepsy syndromes were the second most common etiology, followed by central nervous system (CNS) infections, structural brain abnormalities, metabolic disorders, vascular lesions, toxins, and immune-mediated causes, in that order. In 14 (6.36%) children, the etiology was unknown at the time of the study. Conclusions First-episode seizures in children cause physical, mental, and financial stress on the parents. The collection of detailed history, examinations, and appropriate investigations can help identify the etiology of seizures. It was possible to determine the etiology of the first episode of a seizure in the majority of the patients. Generalized-onset seizures were the most common. Febrile seizures, epilepsy syndrome, CNS infections, vascular lesions, and metabolic disorders were the main etiological factors, in that order.
RESUMO
BACKGROUND: There is a lack of data on the safety of providing oxygen at home to stable patients recovering from COVID-19. METHODS: A retrospective analysis of patients discharged to a COVID-19 virtual ward (CVW) between January 2021 and March 2021 at a UK district general hospital was performed. Patients with improving clinical trajectories and oxygen requirements up to 4 L/minute were eligible. Outcomes measured were 30-day mortality and readmission rate. RESULTS: From 02 January 2021 to 16 March 2021 (74 days), 147 patients discharged to the CVW were included: 71 received continuous or ambulatory oxygen, and 76 received pulse oximetry monitoring only. Five patients were readmitted within 30 days and two patients died. There were no significant differences between readmission and mortality rates between those discharged with or without oxygen. CONCLUSION: Provision of oxygen at home for selected patients recovering from COVID-19 is safe with low risk of readmission and death.

BACKGROUND: Sample adequacy for immediate molecular testing is paramount in lung cancer. To date, several endobronchial ultrasound with transbronchial needle aspiration (EBUS-TBNA) sampling setups have been evaluated, however, the utilization of high-pressure suction (HPS) has not yet been reported.The aim of this study was to evaluate the utilization of HPS onto the needle and its effect on sample volume and adequacy for molecular testing in patients with suspected lung cancer. METHODS: We retrospectively analyzed 128 consecutive EBUS-TBNA performed for suspected lung cancer. This was confirmed in 109 patients. Other diagnoses confirmed in 12, and 7 referred for surgery. Sixty-three patients (89 targets) had HPS (May to September 2020), and compared with 46 (72 targets) who had standard vacuum syringe suction (October 2019 to March 2020). Several parameters and outcomes evaluated, such as number of needle passes, needle strokes, needle size, target size, positron emission tomography avidity, procedure time, blood content score, sample volume, adequacy for molecular testing, as well as baseline patient characteristics and complication rate. RESULTS: There was no difference between the 2 groups in all baseline parameters and characteristics. In multivariable analysis, HPS was associated with significantly higher sample volume (11.2 vs. 9.1 mm3, P=0.036) and less additional procedures to achieve full molecular profiling (2/52 vs. 7/40, P=0.042), in necrotic targets of non-small cell lung cancer. Diagnostic yields were comparable. CONCLUSION: HPS appears to be simple, no-cost, and safe, promising higher sample volume compared with vacuum syringe suction, and also appears to be associated with higher success of full molecular testing with less additional procedures, in non-small cell lung cancer necrotic targets.
