Abstract
Objective Retinal tears are the most common vitreoretinal (VR) emergency and retinopexy aims to reduce the risk of rhegmatogenous retinal detachment (RRD). Currently retinal laser is a required competence by the Royal College of Ophthalmologists for residents. We report 6-month detachment rate and repeat retinopexy rate of VR specialists compared with residents. Methods and analysis A retrospective, consecutive study of 958 eyes undergoing primary laser retinopexy (slit lamp or indirect laser) from January 2017–2020 was divided into training level by operator: specialty training (ST) 2–3, ST4–5, ST6–7 and VR specialists. Results We report an overall 6-month RRD rate in 32/958 (3.3%) (ST2–3: 9/221 (4.1%), ST4–5: 15/373 (4.0%), ST6–7: 2/72 (2.8%) and VR specialists: 6/292 (2.1%)). We additionally report a repeat retinopexy rate of 189/958 (19.7%), (ST2–3: 44/221 (19.9%), ST4–5: 80/373 (21.4%), ST6–7: 16/72 (22.8%) and VR specialists: 49/292 (16.8%)]). Multivariable Cox survival regression analysis showed significant risk factors for developing RRD include male gender (p=0.018), high myopia (≤−6.00 Dioptres, p=0.004), ST2–3 (p=0.022) and ST4–5 (p=0.040) (relative to VR specialists) and by ST6–7, no significance was found (p=0.151). Significantly higher repeat retinopexy rates were associated with horseshoe tears (relative to round holes, p<0.001) and high myopia (p=0.026) with no difference between different training levels. Conclusion There was a decreasing trend in RRD rate following primary retinopexy with increase in training. Although junior residents had a higher RRD rate than VR specialists, it was still favourable relative to other large case series. While there was no difference in subsequent laser retinopexy rate between training levels, the retreatment rate was associated with the type of tear and high myopia.

Abstract
BACKGROUND AND OBJECTIVE Rhegmatogenous retinal detachment (RRD) repair by pars plana vitrectomy and gas tamponade (GT) has significant clinical and quality-of-life impacts compared with repair by short-acting air tamponade (AT). With AT, most authors minimize cryotherapy because of prolonged chorioretinal scar formation and use perfluorocarbon to maximize subretinal fluid drainage; this deviates from traditional technique, which discourages popularization of AT. PATIENTS AND METHODS Prospective 12-month study from January to December 2019 of all primary macula-on RRD cases. Patients fulfilling the inclusion criteria for the Pneumatic Retinopexy Versus Vitrectomy for Retinal Detachment Trial received AT and otherwise were assigned to receive GT. RESULTS Forty-six patients were enrolled: 22 (48%) receiving AT and 24 (52%) receiving GT. The primary success rate of AT was 21 (95%) and the primary success rate of GT was 23 (96%), with 100% final success. Cryopexy was used in 64% of AT cases and 58% of GT cases. Cataract surgery was required less when AT was used (1 [6%]) than when GT was used (3 [21%]). AT was used in 48% of primary macula-on RRD and 27% of all primary RRD cases. CONCLUSIONS AT has visual and anatomical outcomes comparable to those of GT with conventional vitrectomy techniques, with faster postoperative rehabilitation enabling a swift return to normal daily activities.

Abstract
PURPOSE To investigate different baseline characteristics, clinical indications, repeat retinopexy rate, and 6-month detachment rate of primary laser retinopexy across different ethnicities. METHOD Retrospective, single-centre, consecutive comparative study, looking at all patients who had primary laser retinopexy between January 2017 and 2020. Multivariate Cox survival [reporting hazard ratio (HR)] and binary logistic regression (reporting odds ratio) analyses were performed to investigate differences between ethnicities with age, gender, operator level (vitreoretinal or general ophthalmologist) and high myopia status (≤-6.0 Dioptres) as covariates. RESULTS We report on 812 patients in three ethnicities: Black [69 (8.5%)], South Asian [SA, 156 (19.2%)] and White [587 (72.3%)] with overall 6-month detachment rate of 31 (3.8%). Rate for subsequent retinopexies was Black: 12 (17.4%), SA: 15 (9.6%) and White: 131 (22.3%), p = 0.002. Multivariate Cox survival regression analysis found no difference in detachment rate between ethnicities. South Asian (SA) had lower repeat retinopexy rate than White patients [HR, 0.40 (95% confidence interval [CI], 0.22-0.71, p = 0.002)]. Multivariate binary logistic regression found that Black and SA patients compared with White, have the following: (i) higher proportion of round holes relative to horseshoe tears [OR, 2.31 (95% CI, 1.19-4.49, p = 0.014) and OR, 2.06 (95% CI, 1.25-3.40), p = 0.004, respectively] and (ii) higher proportion of high myopia [OR, 2.99 (95% CI, 1.20-7.46, p = 0.019) and OR, 2.35 (95% CI, 1.11-4.96), p = 0.025, respectively]. Ethnic minorities were younger than White patients: SA [43, interquartile range (IQR), 28-61], Black (49, IQR, 35-57) and White (61, IQR, 54-67 years, p < 0.001) and had more indirect and 360 retinopexy compared with slit lamp (p < 0.001). CONCLUSION We demonstrate a significant difference in baseline characteristics, retinal tear morphology and treatment course between the ethnic groups. Further studies are necessary to investigate the genetic and biological differences that may influence these variations and may help to allow for more targeted health care.

Abstract
Purpose Socio-economic deprivation and ethnic variation have been frequently linked to poorer health outcomes. We collected a large series of primary macula-on rhegmatogenous retinal detachment (RRD) cases and analysed the effect of socio-economic deprivation and ethnicity on both six-month retinal re-detachment rate and visual outcomes. Materials and methods Retrospective consecutive case series of 568 patients attending Birmingham and Midlands Eye Centre from January 2017–2020. Multiple Indices of Deprivation (IMD) deciles were used for deprivation status and split to two groups: IMD-A (Decile 1–5) and IMD-B (Decile 6–10). The two largest subgroups of ethnicities were compared, White and South Asians (SA). Results We report an overall retinal re-detachment rate of 8.5%. IMD-A re-detached significantly more than IMD-B (11.2% vs 6.0% respectively, p = 0.034). No statistical significance was found between White and SA re-detachment rate (9.1% and 5.6% respectively, p = 0.604). SA median age significantly lower at 49 years (IQR: 37–61) compared to White patients at 57 years (IQR: 50–65) (p = <0.001). IMD-A median age of 55 years (IQR: 46–64) was significantly lower to IMD-B median age of 58 years (IQR: 51–65) (p = 0.011). No differences in final visual outcomes were detected across all groups. Conclusion We demonstrated an increased retinal re-detachment rate in our more deprived patients according to IMD and a younger cohort of SA compared to White ethnicity. Further prospective studies are required to demonstrate the link between socio-economic deprivation and surgical success.

Abstract
Abstract
Introduction
The COVID-19 pandemic provoked a change to normal surgical practice and led to a higher proportion of acute appendicitis (AA) patients being treated conservatively with antibiotics. We aim to analyse patients presenting with AA during the first wave of the pandemic, comparing surgically and conservatively managed patients.
Method
All patients presenting to our centre with AA between March and July 2020 were included. Six-month follow-up data was collected retrospectively using electronic records. Patients were categorised into surgically and conservatively managed groups. The primary outcome was the complication rate (post-operative complications vs failure of antibiotic treatment) and the secondary outcome was length of hospital stay.
Results
Fifty-seven patients (n = 57) were admitted with AA, 45.6% (n = 26) managed conservatively compared to 54.4% (n = 31) treated surgically. Higher complication rates were observed amongst the conservatively managed group, although not statistically significant (16% vs 35%; p = 0.131). There was no significant difference in length of hospital stay observed between the two groups (surgical: median, 2; interquartile range, 2-3 vs conservative: median, 3; interquartile range, 2-4). White cell count (WCC) and Alvarado score were higher on admission in the surgical group with statistical significance (p = 0.012 and p = 0.028 respectively).
Conclusions
Stratification criteria, such as Alvarado score and WCC may identify patients more suitable for conservative management. Longer term follow-up will be carried out, which may alter complication rates in either group. We suggest all patients treated conservatively should undergo computerised tomography (CT) to exclude complicated appendicitis. Further UK-based studies will add to the evidence-base surrounding management of AA during the COVID-19 pandemic.

Abstract
BACKGROUND AND OBJECTIVE To assess the refractive outcomes in patients who underwent combined phacovitrectomy for retinal detachment compared to phacoemulsification and intraocular lens (IOL) implant utilizing newer swept-source optical-coherence-tomography (SS-OCT) biometry and determine the requirement of an adjustment factor for superior predicted refractive outcomes. PATIENTS AND METHODS Retrospective study of 95 eyes: 52 eyes that underwent phacovitrectomy and 43 eyes with phacoemulsification only that served as the control group. Mean refractive error (ME) and mean absolute error (MAE) were used to compare the groups. RESULTS No statistically significant postoperative refractive shift was found between phacoemulsification and phacovitrectomy eyes for (1) ME (0.05 D [± 0.51 diopters (D)] and (0.03 [± 0.73 D], respectively; P = .348), (2) MAE (0.41 D ± 0.29 D and 0.60 ± 0.44 D, respectively), or (3) MAE of the control compared to macula-on/off eyes (P = .160 and P = .078, respectively). CONCLUSION The authors do not recommend an adjustment factor for IOL selection when utilizing SS-OCT biometry, as it provided refractive outcomes superior to those found in previous studies utilizing a partial coherence interferometry system.

Abstract
BACKGROUND Microbial keratitis (MK) is the most common non-surgical ophthalmic emergency, and can rapidly progress, causing irreversible sight-loss. This study explored whether the COVID-19 (C19) national lockdown impacted upon the clinical presentation and outcomes of MK at a UK tertiary-care centre. METHODS Medical records were retrospectively reviewed for all patients with presumed MK requiring corneal scrapes, presenting between 23rd March and 30th June in 2020 (Y2020), and the equivalent time windows in 2017, 2018 and 2019 (pre-C19). RESULTS In total, 181 and 49 patients presented during the pre-C19 and Y2020 periods, respectively. In Y2020, concurrent ocular trauma (16.3% vs. 5.5%, p = 0.030) and immunosuppression use (12.2% vs 1.7%, p = 0.004) were more prevalent. Despite proportionately fewer ward admissions during the pandemic (8.2% vs 32.6%, p<0.001), no differences were observed in baseline demographics; presenting visual acuity (VA; median 0.6 vs 0.6 LogMAR, p = 0.785); ulcer area (4.0 vs 3.0mm2, p = 0.520); or final VA (0.30 vs 0.30 LogMAR, p = 0.990). Whilst the overall rates of culture positivity were similar in Y2020 and pre-C19 (49.0% vs. 54.7%, p = 0.520), there were differences in the cultures isolated, with a lower rate of poly-microbial cultures in Y2020 (8.3% vs. 31.3%, p = 0.022). CONCLUSIONS Patient characteristics, MK severity and final visual outcomes did not appear to be affected in the first UK lockdown, despite fewer patients being admitted for care. Concurrent trauma and systemic immunosuppression use were greater than in previous years. The difference in spectra of isolated organisms may relate to behavioural changes, such as increased hand hygiene.

Abstract
PURPOSE To compare refractive outcomes and accuracy of modern optical biometry, swept-source optical coherence tomography, ultrasound biometry, and effect of the macula status in rhegmatogenous retinal detachment managed with either combined phacovitrectomy or sequential vitrectomy and cataract surgery compared with a control, phacoemulsification alone. METHODS Retrospective, comparative, consecutive study of 154 eyes; Group 1 underwent phacovitrectomy (n: 70), Group 2 underwent vitrectomy with subsequent cataract surgery (n: 41), and Group 3 underwent cataract surgery alone (n: 43). RESULTS No difference in the mean absolute error was found between Group 2 (0.41 ± 0.56) and Group 3 (0.41 ± 0.29); both were superior to Group 1 (0.74 ± 0.57). Between Group 1 and Group 2, no statistically significant difference in the mean absolute error was found between macula-on subgroups (P = 0.057), but this was statistically significant between macula-off subgroups (P = 0.009). Subgroup analysis by biometry showed that the difference in the mean absolute error between macula-off optical biometry Group 1 and Group 2 against our control, Group 3, were not significant (P = 0.078 and P = 0.119, respectively); the mean absolute error was significantly different when considering macula-off ultrasound biometry cases (P < 0.001 and P = 0.038, respectively). CONCLUSION All three groups had comparable refractive outcomes when using optical biometry. However, phacovitrectomy macula-off cases had inferior refractive outcomes when the ultrasound biometry had to be used. In macula-off rhegmatogenous retinal detachment, when optical biometry is not reliable, it is preferable to perform sequential surgery rather than phacovitrectomy.

Conclusions COVID-19 has led to a significant cohort of conservatively managed AA patients in the United Kingdom. We propose a stratification pathway based on clinical severity, Alvarado score and imaging to facilitate safe selection for conservative management of AA, in order to reduce failure of treatment rates in this patient group. Further UK-based studies will add to the evidence-based surrounding safe management of AA with conservative treatment.

Abstract
PURPOSE To review the effect of COVID-19 on rhegmatogenous retinal detachment (RRD) rate following primary retinopexy. METHODS Retrospective consecutive case series of 183 patients attending Birmingham and Midlands Eye Centre undergoing primary retinopexy (cryotherapy and laser) between March 23rd to June 30th in 2019 (Group 1) and 2020 (Group 2). RESULTS In total we reviewed 183 retinopexies, 122 in Group 1 and 61 in Group 2, a reduction of 50%. In Group 2 compared to Group 1, we showed a significant difference in characteristics of patients having primary retinopexy with an increase in proportion of male patients from 50 (41.0%) to 39 (63.9%) (p = 0.005), increase in high myopes from 1 (0.8%) to 4 (6.6%) (p = 0.043), more slit lamp laser retinopexy from 83 (68.0%) to 52 (85.2%) (p = 0.013) and less cryopexy from 21 (17.2%) to 2 (3.3%) (p = 0.008). In Group 2, primary retinopexy resulted in significantly more 3-month RRD rate 1 (0.8%) to 5 (8.2%) (p = 0.016). There were no changes in number of patients requiring further retinopexy (p = 1.000). CONCLUSION This study demonstrates a reduction of primary retinopexy, an increased risk for RRD following primary retinopexy and a significant shift in type of primary retinopexy performed, demographics, operator and change in characteristics of type of retinal break observed during this pandemic. This study contributes to the growing literature of the secondary effects of the COVID-19 pandemic on other aspects of healthcare that is not just limited to the virus itself.

Abstract
INTRODUCTION Rhegmatogenous retinal detachment (RRD) is commonly managed by pars plana vitrectomy (PPV). Gas tamponade has significant clinical and quality of life factors that affect the patient. Using shorter acting air tamponade, intuitively leads to surgical concern for higher rate of primary detachment. To circumvent this, surgeons advocate the use of perfluorocarbon to maximise sub-retinal-fluid drainage when using air tamponade and/or avoid using cryotherapy due to longer duration for scar formation relative to laser. These steps are a deviation from traditional technique for otherwise routine primary RRD repair and discourages popularisation of using air tamponade despite the benefits to patients. METHOD Prospective 12-month, single centre, single surgeon, consecutive study from January to December 2019. Inclusion criteria was as per based on the pneumatic retinopexy versus vitrectomy for retinal detachment: (i) single retinal break or group of breaks, no larger than 1-clock-hour (30°), in detached retina; (ii) all breaks in detached retina lie above the 8 to 4 o'clock meridian; and (iii) breaks or lattice degeneration in attached retina at any location. We excluded PVR formation and RRD in the inferior 4 o'clock hours. RESULTS We report primary and final success rate of 96% and 100%, respectively in 23 eyes (22 macular-on and one macular-off) with RRD eyes in a 12-month period. Cryopexy was utilised in 65% patients and in isolation in 23% with no perfluorocarbon use in all eyes. CONCLUSION We show cryotherapy can be used safely in AT-RRD without PFCL in RRD fulfilling PIVOT trial criteria with minimal cataract formation and IOP spikes and faster post-operative visual rehabilitation.

[PMID: 33288899 PMCID: PMC8302743 DOI: 10.1038/s41433-020-01333-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 09/25/2020] [Accepted: 11/17/2020] [Indexed: 11/10/2022] Open
Abstract
Purpose Microbial keratitis (MK) is the most common non-surgical ophthalmic emergency admission in the UK. However, few prospective health-economic studies of MK have been performed, and no specific healthcare resources group (HRG) code exists. This study is designed to determine the feasibility of a data collection tool derived from the microbiology ophthalmology group (MOG) clinical record form, to enable quantification of direct costs of inpatient care, as well as prospective capture of epidemiological data relating to outcomes of MK. Methods Clinical, demographic and economic data were collected retrospectively between January and December 2013 for 101 consecutive patients admitted with MK, using an adaption of the MOG toolset. The direct cost of admission (COA) was calculated using national reference costs and compared to actual income to generate profit/deficit profiles for individual patients. Indices of multiple deprivation were used to assess effect of deprivation on the COA. Results The total income generated through discharge coding was £252,116, compared to a COA of £357,075, yielding a deficit of £104,960 (median: £754 per patient). The cost deficit increased significantly with length of stay (LOS, p < 0.001), whilst patients with short LOS were income generators; cost neutrality occurred at 4.8 days. Greater socioeconomic deprivation was also associated with a significantly higher cost deficit. Conclusion LOS is the key driver for COA of care for MK admissions. Protocols should encourage discharge of patients who are able to self-administer treatment after the sterilisation phase. The MOG-derived data collection toolset captures pertinent clinical data for quantification of COA. Further development into a multiuser and multisite platform is required for robust prospective testing, together with expansion to capture indirect costs of disease burden, including impact of treatment, visual morbidity and quality of life.

Abstract
BACKGROUND/AIMS Maintaining emergency eye services is crucial during the COVID-19 pandemic. This article describes the introduction of a new restructured referral pathway to reduce the burden on healthcare providers and create a safe environment. METHODS During January and February 2020 (group 1), all appointments were face-to-face with a walk-in eye casualty. The first audit cycle comprised all patients in group 1. The primary audit criteria were discharge rates, referral to subspeciality and reattendance. In April 2020, a remodelled system was implemented in which walk-in attendance ceased and was replaced with telephone triage coupled with digital imaging via NHS email for remote clinical review. Patients requiring further assessment following this triage were invited in for face-to-face appointments. A reaudit was conducted during April-July 2020 (group 2) following implementation of these COVID-19 protocol changes. RESULTS In group 1, 2868 appointments (100.0%) were face-to-face and in group 2 4870 (100.0%) appointments were telephone consults that resulted in 2639 (54.2%) face-to-face appointments. The rate of discharge in the first cycle and second cycle were 55.3% and 76.9% respectively (P<0.0001). Furthermore 2298 (47.2%) patients were able to be discharged following telephone consultation in group 2. CONCLUSIONS Using this telephone and digital imaging review triage system, the authors have demonstrated a significant reduction in the need for face-to-face reviews. The reduction in avoidable patient face-to-face reviews allows the system to move from saturated to sustainable while increasing accessibility to services for patients who may not be able to present for face-to-face review. This complete audit cycle successfully charts interventions that maximise accessibility, reduce unnecessary hospital visits and deliver safe and prompt management during the pandemic.

Abstract
BACKGROUND Whilst research and innovation is embedded within the UK's National Health Service (NHS) constitution, Doctors-in-training have little opportunity to contribute to designing, leading and recruiting into clinical trials or cohort studies. We formed the West Midlands Collaborative Ophthalmology Network for Clinical Effectiveness & Research by Trainees (The West Midlands CONCERT) and undertook a characterisation of post cataract surgery endophthalmitis as a proof-of-concept study to test the feasibility of the CONCERT model. METHODS Doctors-in-training formed a collaborative working group to test the concept of delivering a pan-regional clinical effectiveness study across multiple hospital sites by performing retrospective analyses of post cataract endophthalmitis over a 6-year period. RESULTS Overall, 157,653 cataract surgeries were performed by participating centres accredited to deliver the Royal College of Ophthalmologists training curriculum. Thirty-eight cases of post cataract endophthalmitis were identified, giving an incidence of 2.41 per 10,000 cases (0.0241%). A further 15 endophthalmitis cases presented who had surgery in non-training centres, giving a total of 53 cases. The most common organisms were S. epidermidis (14 (51.9%)) and P. aeruginosa (5 (18.5%)). Anterior-chamber and vitreous sampling yielded positive culture in 33.3% (6/18) and 50.9% (27/53), respectively. At 6 months follow-up, 19 (51.4%) patients achieved visual acuities of ≤0.5 LogMAR. Repeat intravitreal injections (11 (20.8%)) and vitrectomy (n = 22 (41.5%)) were not associated with better outcomes. CONCLUSIONS Using post cataract endophthalmitis as a pilot cohort, this study highlights the feasibility of using the CONCERT model for studies across multiple sites. A UK-CONCERT could provide a powerful infrastructure enabling characterisation of patient cohorts and a platform for high-quality interventional studies, improving patient care.

Abstract
BACKGROUND During the current coronavirus (COVID-19) pandemic, some ophthalmologists across the United Kingdom (UK) have been redeployed to areas of need across the National Health Service (NHS). This survey was performed to assess aspects of this process including training & education, tasks expected, availability of personal protection equipment (PPE) used and the overall anxiety of ophthalmologists around their redeployment. METHOD Online anonymous survey around the existing guidance on safe redeployment of secondary care NHS staff and PPE use by NHS England and Public Health England respectively. The survey was open to all ophthalmologists across the UK irrespective of their redeployment status. FINDINGS 145 surveys were completed and returned during a 2-week period between 17th April 2020 and 1st May 2020, when 52% of ophthalmologists were redeployed. The majority of this group consisted of ophthalmologists in training (79%). 81% of those redeployed were assigned to areas of the hospital where patients with confirmed Coronavirus disease were being treated as inpatients. There was a statistically significant improvement in anxiety level following redeployment which was mainly attributed to the support received by staff within the redeployed area. 71% of the redeployed group were found to have sufficient PPE was provided for the area they worked in. INTERPRETATION This is the first national survey performed on redeployment of ophthalmologists in the UK. The study showed that ophthalmologists across all grades were able to contribute in most aspects of patient care. Anxiety of redeployment was reduced by prior training and good support in the redeployment area.

Abstract
Diagnosis of cutaneous forms of lupus erythematosus (LE), including chronic discoid LE (CDLE) and subacute cutaneous LE (SCLE), is usually based on characteristic clinical and histopathological findings. We aimed to visualize morphological changes in lesions of cutaneous LE using optical coherence tomography (OCT), and to correlate the OCT findings with histopathology. Six patients with CDLE and five patients with SCLE were investigated. Prior to skin biopsy, OCT assessment was performed on previously marked lesions. The images of OCT and corresponding histology were evaluated side-by-side on the PC screen. The thickening and disruption of the entrance signal in OCT images correlated with the hyperkeratosis which was observed in the histological sections. Atrophy of the epidermis, which was demonstrated by histology, could also be detected in the OCT pictures showing a thinned layer below the entrance signals. On OCT, a patchy reduction of reflectivity was observed in the upper dermis corresponding to dense patchy, partly lichenoid, lymphocytic infiltrates and oedema of the upper dermis. Furthermore, OCT images displayed increased signal-free cavities which histopathologically corresponded to dilated vessels in the upper dermis. All OCT parameters studied significantly (P < 0.05) correlated with histopathological features as indicated by coefficients of correlation ranging from 0.55 to 0.94. OCT enables to demonstrate micromorphological changes in cutaneous LE which correlate with histopathological findings. Nevertheless, the current technique does not allow one to visualize definite diagnostic features of cutaneous LE. However, OCT may be a promising method for objective monitoring of LE activity and treatment effects over time in vivo

Abstract
PURPOSE To determine the long-term safety of discontinuation of maintenance therapy for cytomegalovirus retinitis (CMVR) and to identify predictors for relapse. METHOD This was a prospective cohort study. Patients with treated CMVR who responded to HAART were followed by ophthalmologic assessment, markers for CMV replication (blood and urine cultures, CMV antigenemia, CMV DNA by PCR), and in vitro lymphoproliferative responses to CMV and other antigens after discontinuation of CMVR maintenance therapy. RESULTS 23 patients were followed a median of 34 (range, 5-61) months. Median CD4 count was 321/mm3 at enrollment and 395/mm3 at last follow-up. HIV RNA was <50 copies/mL in 78% of patients at enrollment and 65% at last follow-up. One CMVR reactivation occurred at 12 months at a CD4 count of 395/mm3 (21%) and HIV RNA <50 copies/mL. Urine cultures were a poor predictive marker for reactivation. Other CMV replication markers had good negative predictive value. 96% of patients had a good lymphoproliferative response to CMV antigen in vitro. CONCLUSION Maintenance therapy for CMVR can safely be discontinued in patients who have responded to HAART. Combining our results with the published literature, the risk of reactivation is estimated at 0.016 per person year of follow-up. Markers to predict relapse and the need for re-initiation of maintenance therapy are not yet identified.

Abstract
INTRODUCTION We present a rare case of a liver volvulus, stomach and transverse colon herniating through the diaphragm. This scenario has not been reported previously. We discuss the presentation and management of this interesting case. CASE HISTORY A 65-year-old woman with a history of sarcoidosis and recurrent pericardial effusions, treated previously with a subxiphoid pericardial oval window fenestration, presented with acute upper abdominal pain radiating to the chest. High contrast computed tomography showed a volvulus of the liver with consequent venous congestion, and herniation of the liver, stomach and transverse colon through an anterior diaphragmatic defect. With liver perfusion threatened, an urgent laparoscopic repair was performed. The stomach and transverse colon were reduced, and the twisted left lobe of the liver was unrotated and reduced into the abdominal cavity. A double-sided synthetic mesh was used to repair the defect. The patient made an uneventful recovery. CONCLUSIONS This is a novel complication of a patient presenting with abdominal pain with a previous history of pericardial window fenestration. A laparoscopic reduction and repair can be performed safely with excellent postoperative results.

Abstract
Reactivation of certain latent viruses has been linked with a more severe course of drug-induced hypersensitivity reaction (HSR). For example, reactivation of human herpes virus (HHV)-6 is associated with severe organ involvement and a prolonged course of disease. The present study discusses an HSR developed in a previously healthy male exposed to ceftriaxone, doxycycline, vancomycin, and trimethoprim/sulfamethoxazole (co-trimoxazole; TMP/SMX). Initially, the patient presented clinical manifestations of HSR, as well as clinical and laboratory measurements compatible with liver and renal failure. Moreover, the patient presented skin desquamation compatible with Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis. During the reaction, it was observed HHV-6 reactivation. The severity of clinical symptoms is correlated with HHV-6 titer, as well as with results of the in vitro lymphocyte toxicity assay (LTA). Serum levels of a large panel of cytokines are compared between the patient, a large population of SJS patients, and a cohort of healthy controls, using data collected by our laboratory over the years. HHV-6 was measured in the cell culture media from lymphocytes incubated with each of the 4 drugs. Moreover, we describe a new assay using cytokines released by patient lymphocytes following in vitro exposure to the incriminated drugs as biomarkers of HSR. Based on LTA results, HHV-6 reactivation and cytokine measurements, we establish that only doxycycline and TMP/SMX were involved in the HSR. As result of this analysis, the patient could continue to use the other 2 antibiotics safely.

Abstract
Late-onset cytomegalovirus (CMV) disease commonly occurs after discontinuation of antiviral prophylaxis. We determined the utility of testing CD8+ T-cell response against CMV as a predictor of late-onset CMV disease after a standard course of antiviral prophylaxis. Transplant patients at high-risk for CMV disease were enrolled. CD8+ T-cell-mediated immunity (CMI) was tested using the QuantiFERON-CMV assay at baseline, 1, 2 and 3 months posttransplant by measurement of interferon-gamma response to whole blood stimulation with a 21-peptide pool. The primary outcome was the ability of CMI testing to predict CMV disease in the first 6 months posttransplant. There were 108 evaluable patients (D+/R+ n = 39; D-/R+ n = 34; D+/R- n = 35) of whom 18 (16.7%) developed symptomatic CMV disease. At the end of prophylaxis, CMI was detectable in 38/108 (35.2%) patients (cutoff 0.1 IU/mL interferon-gamma). CMV disease occurred in 2/38 (5.3%) patients with a detectable interferon-gamma response versus 16/70 (22.9%) patients with a negative response; p = 0.038. In the subgroup of D+/R- patients, CMV disease occurred in 1/10 (10.0%) patients with a detectable interferon-gamma response (cutoff 0.1 IU/mL) versus 10/25 (40.0%) patients with a negative CMI, p = 0.12. Monitoring of CMI may be useful for predicting late-onset CMV disease.
