Introduction: Ocular symptoms are uncommon manifestations of coronavirus disease 2019 (COVID-19) infection. Earlier study reported that dry eye, blurred vision, foreign body sensation, tearing, itching, conjunctival secretion, conjunctival congestion, ocular pain, and photophobia are among the ocular symptoms that could be found in COVID-19 patients. However, there are only a few reports available regarding corneal involvement in this disease. Here we report a case of keratoconjunctivitis as the only symptom of COVID-19 infection. Case description: A 27-year-old man who worked as an obstetrics and gynecology resident came to the outpatient clinic with the chief complaints of eye discomfort, foreign body sensation, conjunctival hyperemia, lacrimation, and photophobia in his right eye for the past 3 weeks. Fluorescence test showed a small corneal lesion. The patient was then diagnosed with keratoconjunctivitis. A week after the treatment, all symptoms were resolved. A month later, the patient came to the emergency room with the same eye complaints but with a more severe pain. The fluorescence test showed wider corneal lesion compared to last month. The result from the corneal swab is negative for bacterial or fungal infection, indicating a viral infection. Afterwards, reverse transcriptase polymerase chain reaction test from nasopharyngeal swab was performed and revealed that the patient was positive for COVID-19. Conclusions: This case report showed that keratoconjunctivitis may occur as the only manifestation of COVID-19 infection. Thus, patient presented with unexplainable eye symptoms should be evaluated for COVID-19 infection.

Background: Although orphans are at increased risk of undernutrition, studies assessing prevalence of undernutrition are limited to orphans residing with their relatives or on street. This study was conducted to assess magnitude of undernutrition and its associated factors among institutionalized school-age orphans in Harari Regional State, eastern Ethiopia. Methods: An institution based cross-sectional study was conducted among all school-age (6-12 years) orphans living in all orphan centers in Harari Regional State, eastern Ethiopia. Data were collected by using a structured pretested questionnaire supplemented with anthropometric measurements. Data were entered using EpiData 3.1 and analyzed using SPSS 22. Logistic regression models were fitted to identify factors associated with undernutrition. Statistical significance was declared at P-value <.05. Results: A total of 265 orphans residing in all orphan centers in the region were included. The prevalence of stunting, wasting, and underweight were 15.8% (95% CI: 11.9, 20.7), 10.9% (95% CI: 7.7, 15.3), and 8.7% (95% CI: 4.3, 10.5), respectively. Staying in orphan center for 6 to 10 years (AOR = 6.2; 95% CI: 2.6, 15.10), having recent illness (AOR = 3.9; 95% CI: 1.4, 10.4), and being aged 10 to 12 years (AOR = 11.2; 95% CI: 3.5, 35.4) were significantly associated with stunting whereas having recent illness (AOR = 4.3; 95% CI: 1.4, 7.3) and being aged 6 to 7 years (AOR: 10.4; 95% CI: 3.2, 33.6) were significantly associated with wasting. Underweight was more likely (AOR: 8.9; 95% CI: 2.7, 29.5) among children with recent illness. Conclusions: Almost 1 in 6, 1 in 9, and 1 in 11 institutionalized school-age orphans in Harari Regional State were stunted, wasted, and underweight respectively. Younger children and those with recent illness were more likely to be undernourished. Underlying reasons for undernutrition among orphans being cared in orphan centers should be further explored.

Background: Certain nutrients have shown protective effects against frailty, but less is known about the influence of individual food groups. Thus, this study aimed to investigate the relationship between the intake of different food groups and physical frailty in a cohort of community-dwelling older adults in Cork, Ireland. Methods: One hundred and forty-two (n = 81 females, n = 61 males, age 74.1 ± 6.80 years) Irish community-dwelling volunteers aged ⩾65 years participated in this cross-sectional study. Dietary intake was assessed using a validated food frequency questionnaire (FFQ). Frailty was identified as having 3 or more of the following criteria: weight loss, exhaustion, weakness, slow walking speed and low physical activity. Relationships between intakes of food groups and frailty score were determined using Spearman’s rank (and partial rank) correlations and ordinal logistic regression analysis. Results: Negative Spearman’s rank correlations were observed between frailty score and fish and fish products, fruit and vegetables and nuts and seeds, while positive correlations were found between frailty score and potatoes, fats and oils and sugars, preserves and snacks ( P < .05). After adjustment for confounders, partial rank correlations remained statistically significant ( P < .05) for all of the above dietary variables, with the exception of nuts and seeds ( P > .05). Following ordinal logistic regression, the odds ratios (ORs) (95%CI) for frailty incidence for those in the lowest tertile of food group intake compared to the highest were; 3.04 (1.09-8.85) for fish and fish products, 4.34 (1.54-13.13) for fruit and vegetables, 1.52 (0.58-4.15) for nuts and seeds, 0.54 (0.19-1.51) for potatoes, 0.58 (0.17-1.95) for fats and oils and 0.49 (0.16-1.47) for sugars, preserves and snacks. Conclusion: This study suggests that intakes of selected food groups are independently associated with frailty. These findings may hold significant relevance for the development of future frailty prevention strategies.

Published: March 2021

Background Livedoid vasculopathy (LV) is a rare disease characterized by livedo racemosa, atrophie blanche, ulcerations, and severe pain. Low molecular weight heparins and rivaroxaban can be used in LV-patients. In addition, intravenous immunoglobulins (IVIG) have been described as treatment-option. Objectives Objective was to investigate the therapeutic effect of IVIG on ulcer, pain and restrictions in daily life. Methods Thirty-two LV-patients who received IVIG at the Department of Dermatology Tübingen between 01/2014 and 06/2019 were identified. Twenty-five of these patients were available for further follow up and were included in the study. Patients were interviewed using a questionnaire focusing on the course of the disease, symptoms, and subjective response to IVIG-treatment. Results Twenty-five patients were included in the study (mean follow up: 28.9 months). Patients received an average of 6.8 cycles (range 1-45) of IVIG during the observed period. Significant improvements were seen regarding skin findings, pain, and limitation of daily activities. Complete remission of symptoms was observed in 68% of patients. Good tolerability of IVIG was shown in 92%. Conclusions A good therapy response regarding ulceration, pain, and daily life restrictions with good tolerability was demonstrated for IVIG (2 g/kg bodyweight over 5 days).

Published: March 2021

Background Palmoplantar keratoderma (PPK) are a heterogenous group of hereditary and acquired disorders that are characterized by excessive epidermal thickening of the palms and/or soles. PPK has been described as a rare adverse event for some medications. The aim of this systematic review was to summarize outcomes in PPK associated with various medications. This data will assist dermatologists and other healthcare providers treating patients with drug-induced PPK. Methods EMBASE and MEDLINE databases were searched in accordance with PRISMA guidelines using the keyword “palmoplantar keratoderma.” 40 studies met the inclusion criteria. Results A total of 247 patients (mean age: 57.0 years) were included in the analysis. Among patients whose sex was reported, 60.3% ( n = 35/58) were male. PPK most frequently developed after treatment with BRAF inhibitors (73.7%, n = 182/247), BRAF inhibitors combined with MEK1/2 inhibitors (15.4%, n = 38/247), tyrosine kinase inhibitors (TKIs) (3.2%, n = 8/247), or chemotherapy (2.4%, n = 6/247). The mean latency period between initiation of the drug and onset of PPK was 7.6 months (range: 0.25-90 months). Improvement of PPK was reported in 24 cases, with 50% ( n = 12/24) achieving complete resolution and 50% ( n = 12/24) achieving partial resolution. All patients who achieved complete resolution stopped the suspected drug, with a mean resolution period of 2.4 months (range: 2 weeks-6 months). The most common treatments for PPK were keratolytic treatments ( n = 10) and topical corticosteroids ( n = 4). Conclusions PPK was most frequently associated with targeted kinase inhibitors, specifically BRAF, MEK1/2, and tyrosine kinase inhibitors.

Published: March 2021

Background: There are fewer multiple sclerosis (MS) relapses during pregnancy, although relapse risk increases in the early post-partum period, as has been predicted by pre-pregnancy or pregnancy disease activity in some studies. Objective: The aim of this study was to evaluate the correlation between magnetic resonance imaging (MRI) changes in the year before pregnancy and the relapse rate in the year post-partum. Methods: An observational retrospective case–control study included 172 pregnancies in 118 females with MS. Statistical analyses were used to evaluate the correlation between MRI and post-partum relapses. Clustered logistic regression was used to investigate the predictors of early post-partum relapses. Results: We found a significant correlation for an active-MRI pre-pregnancy and relapses in the first 3 months post-partum ( p < 0.001). Expanded Disability Status Scale (EDSS) pre-pregnancy and relapses in the first 3 months post-partum were also significantly correlated ( p = 0.009). Using a multivariate model, we predicted which women will not experience post-partum relapse by EDSS and by an active-MRI pre-pregnancy (96.7% specificity; p < 0.001). Conclusion: An active-MRI pre-pregnancy is a strong and sensitive predictor of early post-partum relapse, regardless of whether the woman had clinical evidence of disease activity prior to conception and delivery. This finding could provide clinicians with a strategy to minimize post-partum relapse risk in women with MS planning pregnancy.

Published: March 2021

Objective: To determine the effect of long-term anti-CD20 B-cell-depleting treatment on regulatory T cell immune subsets that are subnormal in untreated MS patients. Methods: 30 clinically stable MS patients, before and over 38 months of ocrelizumab treatment, were compared to 13 healthy controls, 29 therapy-naïve MS, 9 interferon-β-treated MS, 3 rituximab-treated MS, and 3 rituximab-treated patients with other autoimmune inflammatory diseases. CD8, CD28, CD4, and FOXP3 expression in peripheral blood mononuclear cells was quantitated with flow cytometry. Results: CD8+ CD28− regulatory cells rose from one-third of healthy control levels before ocrelizumab treatment (2.68% vs 7.98%), normalized by 12 months (13.5%), and rose to 2.4-fold above healthy controls after 18 months of ocrelizumab therapy (19.0%). CD4+ FOXP3+ regulatory cells were lower in MS than in healthy controls (7.98%) and showed slight long-term decreases with ocrelizumab. CD8+ CD28− and CD4+ FOXP3+ regulatory T cell percentages in IFN-β-treated MS patients were between those of untreated MS and healthy controls. Interpretation: Long-term treatment with ocrelizumab markedly enriches CD8+ CD28− regulatory T cells and corrects the low levels seen in MS before treatment, while slightly decreasing CD4+ FOXP3+ regulatory T cells. Homeostatic enrichment of regulatory CD8 T cells provides a mechanism, in addition to B cell depletion, for the benefits of anti-CD20 treatment in MS.

Objective The safety of minimally invasive mitral valve surgery (MIMVS) in elderly patients is still debated. Our objective was to perform a systematic review and meta-analysis of studies comparing MIMVS with conventional sternotomy (CS) in elderly patients (≥65 years old). Methods We searched PubMed, EMBASE, Web of Science, clinicaltrials.gov, and Cochrane Central Register of Controlled Trials for trials and observational studies comparing MIMVS with CS in patients ≥65 years old presenting for mitral valve surgery. We performed a random-effects meta-analysis of all outcomes. Results The MIMVS group had lower odds of acute renal failure (odds ratio [OR] 0.27; 95% CI 0.10 to 0.78), prolonged intubation (>48 h; OR 0.47; 95% CI 0.31 to 0.70), less blood product transfusion (weighted mean difference [WMD] −0.82 units; 95% CI −1.29 to −0.34 units), shorter ICU length of stay (LOS; WMD −2.57 days; 95% CI −3.24 to −1.90 days) and hospital LOS (WMD −4.06 days; 95% CI −5.19 to −2.94 days). There were no significant differences in the odds of mortality, stroke, respiratory infection, reoperation for bleeding, and postoperative atrial fibrillation. MIMVS was associated with longer cross-clamp (WMD 11.8 min; 95% CI 3.5 to 20.1 min) and cardiopulmonary bypass times (WMD 23.0 min; 95% CI 10.4 to 35.6 min). Conclusions MIMVS in elderly patients is associated with lower postoperative complications, blood transfusion, shorter ICU, and hospital LOS, and longer cross-clamp and bypass times.

Aim: The Salford Lung Study (SLS) in chronic obstructive pulmonary disease (COPD) was a randomised controlled trial evaluating the effectiveness and safety of initiating fluticasone furoate/vilanterol (FF/VI) 100/25 µg versus continuing usual care (UC) in patients with COPD and a history of exacerbations. Here, we investigate the impact of initiating FF/VI on healthcare resource utilisation (HRU) in SLS COPD. Methods: HRU and interventions were determined from patients’ electronic health records. Annual rates of on-treatment all-cause and COPD-related secondary care contacts (SCCs) and primary care contacts (PCCs) for FF/VI versus UC were analysed using a general linear model. Costs were derived from national data sources. Results: Least-squares (LS) mean annual rates of all-cause (9.81 versus 9.36) and COPD-related (1.57 versus 1.48) SCCs were similar for FF/VI and UC, as were rates of all-cause hospitalisations (0.87 versus 0.82). Mean duration of hospital stay/patient was 4.5 and 4.2 days, respectively. COPD-related SCC mean total cost/patient was £484 FF/VI and £475 UC. LS mean annual rates of all-cause PCCs were significantly higher for FF/VI (21.20 versus 18.88 UC; p < 0.001). LS mean annual rates of COPD-related PCCs were similar for FF/VI and UC (2.42 versus 2.46). All-cause PCC mean total cost/patient was £900 FF/VI versus £811 UC, but COPD-related PCC costs were similar (£116 versus £114). Direct COPD-related total medical costs/patient were significantly lower for FF/VI (LS geometric mean £806 versus £963 UC; p < 0.001). Discussion: In patients with COPD and exacerbation history, FF/VI may represent a less costly alternative to current therapies. GlaxoSmithKline plc. study HZC115151; ClinicalTrials.gov NCT01551758.

Published: March 2021

Background: While vancomycin loading doses may facilitate earlier pharmacokinetic–pharmacodynamic target attainment, the impact of loading doses on clinical outcomes remains understudied. Critically ill patients are at highest risk of morbidity and mortality from methicillin resistant Staphylococcus aureus (MRSA) infection and hypothesized to most likely benefit from a loading dose. We sought to determine the association between receipt of a vancomycin loading dose and clinical outcomes in a cohort of critically ill adults. Methods: Four hundred and forty-nine critically ill patients with MRSA cultures isolated from blood or respiratory specimens were eligible for the study. Cohorts were established by receipt of a loading dose (⩾20 mg/kg actual body weight) or not. The primary outcome was clinical failure, a composite outcome of death within 30 days of first MRSA culture, blood cultures positive ⩾7 days, white blood cell count up to 5 days from vancomycin initiation, temperature up to 5 days from vancomycin initiation, or substitution (or addition) of another MRSA agent. Results: There was no difference in the percentage of patients experiencing clinical failure between the loading dose and no loading dose groups (74.8% versus 72.8%; p = 0.698). Secondary outcomes were also similar between groups, including mortality and acute kidney injury, as was subgroup analysis based on site of infection. Exploratory analyses, including assessment of loading dose based on quartiles and a multivariable logistic regression model showed no differences. Conclusion: Use of vancomycin loading doses was not associated with improved clinical outcomes in critically ill patients with MRSA infection.

Objective: Compare the effects of preoperative embolization for carotid body tumor resection on surgical outcomes to carotid body tumor resections without preoperative embolization. Methods: Single-center retrospective review of all consecutive patients who underwent carotid body tumor resection from 2001 to 2019. Surgical outcomes with emphasis on operative time (estimated blood loss and cranial nerve injury) of patients undergoing carotid body tumor resection following preoperative embolization were compared to those undergoing resection alone using unpaired Student’s t-test and Fisher’s exact test. Results: Forty-six patients (15% male, mean age 50 ± 15 years) underwent resection of 49 carotid body tumors. Patients undergoing preoperative embolization ( n = 20 (40%)) had larger mean tumor size (4.0 ± 0.7 vs 3.2 ± 1 cm, p = 0.006), increased Shamblin II/III tumor classification (18 (90%) vs 22 (76%), p < 0.001), operative time (337 ± 195 vs 199 ± 100 min, p = 0.004), and cranial nerve injuries overall (8 (40%) vs 2 (10%), p = 0.01) compared to patients undergoing resection without preoperative embolization ( n = 29 (60%)). In subgroup analysis of Shamblin II/III classification tumors ( n = 40), preoperative embolization ( n = 18) was associated with increased tumor size (4.1 ± 0.6 vs 3.5 ± 0.9 cm, p = 0.01), operative time (351 ± 191 vs 244 ± 105 min, p = 0.02), and cranial nerve injury overall (8 (44%) vs 2 (9%), p = 0.03) compared to resections alone ( n = 19). In further subgroup analysis of large (⩾ 3 cm) tumors ( n = 37), preoperative embolization ( n = 18) was associated with increased operative time (350 ± 191 vs 198 ± 99 min, p = 0.006) and cranial nerve injury overall (8 (44%) vs 2 (11%), p = 0.03) compared to resections alone ( n = 19). There were no significant differences in estimated blood loss, transfusion requirement, or hematoma formation between any of the embolization and non-embolization subgroups. Conclusion: After controlling for tumor Shamblin classification and size, carotid body tumor resections following preoperative embolization were associated with increased operative time and inferior surgical outcomes compared to those tumors undergoing resection alone. Nonetheless, such results remain susceptible to the confounding effects of individual tumor characteristics often used in the decision to perform preoperative embolization, underscoring the need for prospective studies evaluating the utility of preoperative embolization for carotid body tumors.

Published: March 2021

Breaking bad news is challenging in most circumstances, and informing a patient that they have a cancer diagnosis more so. Therefore, most patients have a face-to-face meeting with their doctor to get their cancer diagnosis with many advantages to this method. The SARS-Covid pandemic has forced cancer specialists to change their approach to giving cancer news and telemedicine is being utilised more than ever before. We describe the satisfaction outcomes of a series of patients who were given their cancer diagnosis by telephone during the pandemic. Our evaluation shows that cancer diagnosis can be safely given over the telephone and moreover the results can be used to design a bespoke cancer clinic of the future. Level of evidence: 4
