ABSTRACT
Objectives: Potential cutaneous adverse drug reactions (cADRs) associated with COVID-19 vaccinations are well-known. However, comprehensive evaluation including detailed patient characteristics, vaccine types, signs and symptoms, treatments and outcomes from such cADRs are still lacking in Taiwan. Method(s): A cross-sectional study was conducted from December 2019 to October 2022 to analyze spontaneous ADR reporting data from Taiwan's largest multi-institutional healthcare system. Physicians and pharmacists initially ensured the data quality and completeness of the reported ADR records. Subsequently, we applied descriptive statistics to analyze the patient cohort based on demographic characteristics, administered COVID-19 vaccines, clinical manifestations, and patient management. Result(s): We identified 242 cADRs from 759 reported COVID-19 vaccine-related ADRs, 88.3% of which were judged as "possible" using the Naranjo Scale. The mean age of patients with cADRs was 48.1+/-17.5 years, with the majority (44.2%) of cADRs reported in the 40-64yr old age group. cADRs were more common in women (68.2%) and most of the patients had no history of allergy to vaccines (99.6%). Oxford/AstraZeneca (58.6%) accounted for the most reported brand of COVID-19 vaccines. Patients developed cADRs within 1 to 198 days (median = 5.5 days), and mostly after first-dose vaccination (77.8%). The most frequently reported cADR was rash/eruption (18.7%), followed by itchiness/pruritus (11.7%) and urticaria (9.2%), mainly affecting the lower limbs (23.8%) and upper limbs (22.6%). Medications were prescribed for 65.1% of the cADRs, and signs and symptoms were resolved within 1 to 167 days (median = 7 days) after treatment with oral antihistamines (23.0%), topical corticosteroids (14.6%) or oral corticosteroids (14.4%). Conclusion(s): Our findings provide comprehensive details regarding COVID-19 vaccine-related cADRs in Taiwan. Certain groups, especially women and the middle-aged, who reported a relatively higher rate of cADRs, may benefit from pre-vaccination counseling about the risks of cADRs and the use of appropriate medications.Copyright © 2023
ABSTRACT
Recent advancements in nanotechnology have resulted in improved medicine delivery to the target site. Nanosponges are three-dimensional drug delivery systems that are nanoscale in size and created by cross-linking polymers. The introduction of Nanosponges has been a significant step toward overcoming issues such as drug toxicity, low bioavailability, and predictable medication release. Using a new way of nanotechnology, nanosponges, which are porous with small sponges (below one microm) flowing throughout the body, have demonstrated excellent results in delivering drugs. As a result, they reach the target place, attach to the skin's surface, and slowly release the medicine. Nanosponges can be used to encapsulate a wide range of medicines, including both hydrophilic and lipophilic pharmaceuticals. The medication delivery method using nanosponges is one of the most promising fields in pharmacy. It can be used as a biocatalyst carrier for vaccines, antibodies, enzymes, and proteins to be released. The existing study enlightens on the preparation method, evaluation, and prospective application in a medication delivery system and also focuses on patents filed in the field of nanosponges.Copyright © 2023 The Authors.
ABSTRACT
Objectives: To assess utilization differences in compounded products before and after the COVID-19 pandemic. Secondary objectives were to understand if there were changes in patient cost sharing and types of products compounded pre- and post- pandemic. Method(s): A cross-sectional study was completed using a large national claims database for patients who received at least one COVID-related vaccine, test, or treatment from October 2015 to July 2022. Claims included in the analysis are those identified as paid, listed as compounded, and were filled in 2019, 2020, or 2021. Chi-Square and T-Tests were used to determine if there are differences between each year. Result(s): The prevalence of paid claims for compounded products was 0.00055% (14,101) in 2019, 0.00042% (11,551) in 2020, and 0.00048% (14,005) in 2021. In each year, most claims for compounded products were through commercial insurance 70% in 2019, 62% in 2020, and 65% in 2021. On average there were approximately 2 claims per patient. The most frequently compounded product was lidocaine hydrochloride 20mg/ML topical solution. In 2020 there was an increase in utilization of naltrexone hydrochloride, a treatment for opioid use disorder (OUD). Between 2019 and 2020 the number of compounded claims decreased 17.6% while the number of total claims increased by 9.01%. From 2020 to 2021 the number of claims for compounded products returned to pre-pandemic levels with a 21.24% increase. In the same period, the total number of claims increased 5.86%. The average patient cost sharing for compounded products was $42.57 (SD: $60.02) in 2019, $40.07 ($80.36) in 2020, and $42.61 ($60.02) in 2021. Conclusion(s): We found that there were fewer patients receiving compounded products following the COVID-19 pandemic. We found no change in the number of compounded claims for hydroxychloroquine and ivermectin, though in 2020, there was a notable increase in the number of claims for naltrexone hydrochloride.Copyright © 2023
ABSTRACT
Anosmia associated or not with dysgeusia seems to be a frequent symptom in cases of infection with SARS-CoV-2 responsible for COVID-19. It can be the initial symptom of the disease or remain isolated in pauci-symptomatic patients. Waiting for scientific confirmation and in the context of the current pandemic, it seems essential to consider any patient with a new anosmia as being infected with SARS-CoV-2 until proven otherwise. These patients should therefore isolate themselves and remain alert to the occurrence of other symptoms suggestive of the infection and/or be tested. Topical and systemic corticosteroids and nose washes are contraindicated. The natural course of anosmia seems to be favorable in most cases.Copyright © 2020 Editions Medecine et Hygiene.

ABSTRACT
Objectives: Chilblain lupus erythematosus (LE) is a rare chronic cutaneous lupus erythematosus (CCLE) characterized by the appearance of violaceous plaques in acral regions most exposed to cold. The isolated form affects middle-aged women, while the familial form manifests in early childhood and is associated with mutations in the TREX1 gene. Result(s): A 13-year-old adolescent, with no relevant family history, was referred in March 2021 for suspected chilblain-like lesions associated with COVID-19 infection. The patient presented with multiple violaceous papules on hands and feet. The lesions were slightly painful. Small hyperkeratotic papules were also observed on finger pads. Physical examination also revealed some aphthae affecting the lips. No other systemic symptoms were reported. A skin biopsy and blood tests were performed due to presumed chilblain LE with probable systemic involvement. Histology revealed basal vacuolar damage and intense perivascular and periadnexal lymphocytic inflammatory dermal infiltrate. Remarkably, mucin was noted among the collagen bundles. Leukopenia and positive ANA antibodies (titre 1:320) were detected. Complement levels were normal. SARS-CoV2 infection was ruled out. Skin lesions disappeared within 1 month under topical corticosteroids. Hydroxychloroquine was afterwards started by Rheumatology without recurrence of skin symptoms until last follow-up. Discussion(s): We present an uncommon case of an adolescent with systemic LE presenting as chilblain LE. Chilblain LE can be accompanied by other discoid CCLE. It can progress to systemic LE in up to 20% of patients, especially when concomitant CCLE is present. This rare presentation of CCLE should be differentiated from typical chilblain and other resembling lesions, such as SARS-CoV2-associated chilblain and acral purpuric lesions (COVID toes). The Mayo Clinic diagnostic criteria can be helpful, particularly in this last SARS-CoV2 outbreak scenario, when the reporting of similar skin lesions has been significant.

ABSTRACT
Clinical presentation of COVID-19 infection can be variable in the current pandemic even in patients presenting to the clinic with a mild history of upper respiratory complaints. Various cutaneous manifestations have been noticed in COVID-19 patients with herpes zoster (HZ) being one among them. HZ is an infection that results when varicella zoster virus reactivates from its latent state in the posterior dorsal root ganglion. Here, we aim to expand our knowledge by reporting three cases of associated zoster infection in COVID-19 patients admitted to our intensive care unit in view of respiratory complaints. All the three patients admitted, had revealed lymphocytopenia at the time of HZ diagnosis, and were managed conservatively throughout the course. In all the cases, acyclovir/valacyclovir led to the resolution of lesions in 10 days. No postherpetic sequelae were observed. We here suggest that the clinical presentation of HZ at the time of the current pandemic should be considered as an alarming sign for a latent subclinical SARS CoV-2 infection and thorough follow-up of such patients be adopted.Copyright © 2021 Bali Journal of Anesthesiology.

ABSTRACT
Background/Aims We report the features of chronic chilblain-like digital lesions newly presenting since the start of the covid-19 pandemic. Comparison with primary perniosis and acrocyanosis, reveals a unique phenotype which appears to be a long-covid phenomenon. Methods The case records of 26 patients with new onset persistent chilblain-like lesions presenting to the Rheumatology service of St George's University Hospital, London between Autumn 2020 and Spring 2022 were reviewed. Demographic and clinical features, serology, imaging, treatment response and outcome up to Summer 2022 were collated retrospectively. Results Chilblain-like lesions first occurred between September and March;2019/ 2020 6 cases, 2020/2021 18 cases and 2021/2022 2 cases. Mean age 35.4 (17-60) years, 88% female, 85% white, all non-smokers. Median body mass index (BMI) 20.2, range 17.0 - 33.2. BMI underweight (<18.5) in 27%. All cases reported new red-purple-blue colour changes of the fingers, some with pain, swelling and pruritis, affecting both hands in 12, one hand in 6, and both hands and feet in 8 cases. There was a past history of cold sensitivity or primary Raynaud's in 54%. Covid was confirmed in 3 cases, 2 - 8 months prior to onset of chilblain-like symptoms. Possible covid, unconfirmed, was suspected in 5 cases, 1 - 11 months earlier. Affected digits appeared diffusely erythro-cyanotic in 81%, with blotchy discrete maculo-papular erythematous lesions in 42%, some with both features. Involvement was asymmetric in 54%, thumbs spared in 69%. Complement was low in 50% (8/16), ANA positive in 26% (6/23). MRI of hands showed phalangeal bone marrow oedema in keeping with osteitis in 4 of 7 cases. More severe signs and symptoms were associated with low BMI, low C3/4 and a past history of cold sensitivity or Raynauds. Cold avoidance strategies were sufficient for 58%. Pain prompted a trial of NSAIDs, aspirin, nitrates, calcium channel blockers, hydroxychloroquine, oral or topical corticosteroid or topical tacrolimus in 42%. In general, these were minimally effective or not tolerated. 4 severe cases received sildenafil or tadalafil, effective in 2. In 27% complete remission occurred during the first summer season after symptoms commenced, median duration 6 (range 2 - 10) months. In the remaining 19 cases, chilblain-like symptoms returned or worsened in the subsequent second winter period, with 6 of 19 entering remission the following summer. For the remaining 13 persistent cases the total duration of symptoms spans more than a year, and in four cases more than 2 years. Conclusion This series illustrates a distinct chronic chilblain-like condition. Features similar to primary perniosis include female predominance, middle age, pruritic painful blotchy lesions, asymmetry and low BMI. Features in keeping with acrocyanosis include chronicity, extensive diffuse erythro-cyanotic discoloration, relative improvement in warm weather and lack of association with smoking.
ABSTRACT
Background: Tixagevimab(Txg)/cilgavimab (Cgv) was given emergency use authorization (EUA) to provide passive immunity against COVID-19(CoV) for immunocompromised (IC) pts who may not mount an adequate response to CoV vaccination [1]. Recipients of allogeneic hematopoietic cell transplant (Allo-HCT) are amongst the most IC. Due to high risk of mortality and complications of CoV in this population, Txg/ Cgv was used as pre-exposure prophylaxis (PrEP) under EUA without prior study. Our study aims to assess efficacy and adverse events (AE) of Txg/Cgv administration in this cohort of patients to help guide future practice. Method(s): We retrospectively investigated Allo-HCT recipients who received Txg/Cgv as PrEP. Data were gathered including changes in blood counts, incidence of graft-vs-host-disease (GVHD), history of prior CoV infection and vaccination status. Pts who developed CoV infection after PrEP were assessed for supplemental oxygen(O2) need and hospitalization. Data cutoff date was 9/30/2022. Result(s): A total of 18 Allo-HCT recipients received Txg/Cgv. Table 1 summarizes patient and transplant characteristics. Thirteen (72.2%) pts received 2 doses of 150mg of Txg / Cgv, while 4 pts received 1 dose of 300mg, and one patient received one dose of 150mg. Median time to first dose was 213 days [range 22-3660] post-transplant. Two pts had lab confirmed CoV, one at 24 days post dosing and the 2nd patient at 22 days post dose. Neither required supplemental O2;one was hospitalized for fever. Prior to dosing, 44.4% (8/18) of pts had GVHD. (Table Presented) (Figure Presented) (Figure Presented) Of these, 62.5% (5/8) had no changes in the severity of their GVHD. Two of 8 (25%) pts with pre-existing chronic GVHD had a flare of symptoms. Two (25%) had improvement of GVHD. Two pts developed new onset acute GVHD following Txg/Cgv administration, one requiring 1mg/kg prednisone and the other topical steroids (2/18, 11%). Figure 1 summarizes GVHD patterns observed. Hematologic parameters did not change significantly, see Figure 2. None of the pts reported any subjective AE following dosing. Summary: Txg/Cgv was found to be safe and effective for Allo-HCT pts, without significant toxicity. Two patients had new onset GVHD and 2 patients had progressive GVHD. Whether there is a true association between Txg/Cgv and development of GVHD should be investigated in a larger cohort and then investigated for possible underlying mechanisms.Copyright © 2023 American Society for Transplantation and Cellular Therapy
ABSTRACT
Background: The currently approved vaccines do not induce sterilizing immunity against SAR-CoV-2 infection, and immunity wanes over time. A robust broad spectrum topical prophylaxis strategy could protect vulnerable populations in the face of continuous evolution of SARS-CoV-2. The algal antiviral lectin Griffithsin (GRFT), and an engineered oxidation-resistant variant Q-GRFT have robust entry inhibitory activity against SARS-CoV variants of concern, in addition to other respiratory viruses with pandemic potential. We designed a nasal spray to deliver Q-GRFT to the upper respiratory tract mucosa for on-demand use as a broad-spectrum prophylactic. Two clinical trials (Phase 1a and 1b) were conducted to assess safety, tolerability, and pharmacokinetics of Q-GRFT nasal spray in healthy adults. Method(s): Healthy adult volunteers were enrolled in a Phase 1a double blinded, randomized study to receive a single dose of either intranasal Q-GRFT (3.0 mg, 2 sprays per nostril) or placebo at 2:1 ratio. Following a safety review, the Phase 1b study was initiated. Eleven volunteers in Group 1 received 3.0 mg dose once daily, for 7 days. After a safety review, 11 volunteers in Group 2 received a total of 6.0 mg Q-GRFT (3.0 mg twice daily for 7 days). Topical Q-GRFT concentrations were measured by ELISA in collected nasal and nasopharyngeal fluids. Drug levels in plasma were assayed to determine systemic exposure. Viral microneutralization cytopathic effect (CPE) assays were performed against SARS-CoV-2 Omicron BA-5 and MERS-CoV. Result(s): Eighteen adults (24-54 years;Males 58.3%, Females 41.7%;12 Q-GRFT, 6 Placebo), and 22 adults (aged 23-59 years;Males 52.4%, Females 47.6%) were enrolled in Phase 1a and 1b, respectively. In Phase 1a, a single dose of Q-GRFT maintained quantifiable levels in nasal passages and nasopharynx for up to 24 hours. Similarly, Q-GRFT was quantifiable in nasal and nasopharyngeal regions in the Phase 1b study. No dose accumulation effect or systemic exposure was observed. Nasal and nasopharyngeal swab eluates inhibited SARS-CoV-2 Omicron BA.5 and MERS-CoV in CPE assays. Q-GRFT did not modify olfactory sensation. No severe adverse events were reported. Thus, the nasal spray was deemed safe. Conclusion(s): Intranasal Q-GRFT was safe and enhanced mucosal SARSCoV-2 inhibitory activity in human volunteers. The results support further development of Q-GRFT as a broad-spectrum prophylactic against coronaviruses to curb ongoing infections, and for future pandemic preparedness.
ABSTRACT
Background: COVID-19-related olfactory dysfunction is an emerging problem with a significant impact on the quality of life of affected individuals. Different lines of treatment have been used with varying results. This study aimed to assess the potential therapeutic effect of PRP in the treatment of post-COVID olfactory dysfunction. This work aimed to assess the potential therapeutic effect of platelet-rich plasma (PRP) in treating post-COVID-19 parosmia. A pilot study was conducted on 60 patients with post-COVID parosmia without responding to a 3-month course of olfactory training, topical corticosteroids, omega-three, vitamin B12, and zinc supplementation. The patients were distributed randomly and equally among 2 groups. The case group was subjected to three PRP injections in the olfactory cleft at 3 weeks intervals. The control group continued the pre-study treatment protocol for 6 weeks. The degree of parosmia was assessed before and after treatment subjectively using a visual analog scale (VAS) from 0 to 10. Reaching 0-1 on the visual analog scale was a complete improvement. The primary outcome was assessing the post-treatment score for parosmia 1 month after the third injection in the case group. The second outcome was the comparison between both groups regarding the degree of improvement 1 month after cessation of treatment. Result(s): There was a highly significant improvement in VAS for parosmia (p < 0.00001) in the case group and a significant improvement in VAS for parosmia in the control group (p = P = 0.00148). There was a significant difference between both groups regarding the degree of improvement favoring the case group (p = 0.002). Conclusion(s): Platelet-rich plasma injection in the olfactory cleft offers a therapeutic option for treating patients with post-COVID-19 olfactory parosmia who failed to respond to traditional conservative treatment.Copyright © 2022, The Author(s).
ABSTRACT
Case report Trometamol (tromethamine, tris(hydroxymethyl)aminomethane (TRIS)) is an excipient frequently used as buffer in fluids and semisolid agents, including many drugs such as antibiotics, iodinated contrast agents and the COVID-19 vaccine mRNA-1273. Here, we report the first case of a delayed-type hypersensitivity after oral intake of trometamol. A 64-year- old female patient presented to our emergency department with generalized erythematous rash, pruritus and swelling of the face five hours after the intake of one tablet of fosfomycin trometamol for a urinary tract infection. Further medical history revealed a previous erythematous rash five to six hours after administration of the iodinated contrast agent iopromide. We performed skin prick and intradermal tests with trometamol, fosfomycin trometamol and various iodinated contrast agents, including iopromide, iomeprol, iobitridol, iopamidol and iodixanol. These tests showed no reactions initially. However, 48 hours after intradermal testing, macular erythematous lesions developed at the sites tested with trometamol 0.1%, trometamol 0.01% and all sites tested with iodinated contrast agents. Furthermore, when we performed a lymphocyte transformation test with trometamol, fosfomycin trometamol and iopromide, we recorded a positive reaction with cytokine release after stimulating T cells with trometamol and iopromide. In contrast, basophil activation testing showed a negative result for these agents. Based on these results and our patient's history, we diagnosed a clinically relevant type IV sensitization to trometamol. There are only a few case reports about immediate-type allergic reactions to gadolinium contrast agents caused by the excipient trometamol. There are some published cases which report contact dermatitis after topical administration of trometamol-containing agents. To our knowledge, ours is the first case to report a delayed hypersensitivity reaction to oral administration of trometamol. Excipients are indispensable for drugs, vaccines and other products since they stabilize and preserve the active agents. Nevertheless, excipients should always be considered during an allergy workup, especially if the patient reports prior drug reactions that cannot be explained by a chemical cross-reaction. In our case, we diagnosed delayed-type hypersensitivity to the excipient trometamol. This is a consequential diagnosis for the patient, because trometamol is contained in many drugs and in the COVID-19 vaccine mRNA-1273.
ABSTRACT
Case report Introduction: In the wake of the COVID-19 pandemic, occupational contact dermatitis related to the use of personal protective equipment (PPE) has become increasingly prevalent. While most cases are irritant in nature, allergic contact dermatitis (ACD) remains an important cause of occupational dermatitis. We report a case of ACD to rubber accelerators in the elastic bands of an N95 mask. Informed consent was obtained from the patient for this report. Case Report: A 27-year-old healthcare worker presented with a progressive pruritic eruption over her face and neck, 1 week after she began wearing N95 masks at work. She had only worn disposable surgical masks. She had no medical history apart from hand dermatitis, which was well controlled with topical medications. Examination revealed linear eczematous plaques along her lateral cheeks and posterior neck, corresponding to contact areas between the mask bands and her skin. Patch tests revealed a positive reaction to several rubber accelerators, including Thimerosal, 2-Mercaptobenzothiazole (MBT), and Methylisothiazolinone. We performed another patch test to several N95 mask straps, to which the patient developed an eczematous reaction to the elastic bands of 2 N95 mask types with elastic bands. Clarification with the manufacturer confirmed the use of rubber accelerators similar in properties to MBT in the production of these masks. A diagnosis of allergic contact dermatitis to rubber accelerator was made. The patient's dermatitis resolved with topical corticosteroids and the avoidance of N95 masks with elastic bands. Discussion and Conclusion(s): The use of facial PPE such as masks is a recognised cause of occupational dermatitis among healthcare workers. A variety of dermatoses are associated with the use of facial PPE, with contact dermatitis being the most common. However, while the majority of contact dermatitis are irritant in nature, ACD remains an important and preventable cause of occupational dermatitis. Commonly implicated allergens associated with mask use include preservatives and adhesives used in their production, as well as metals in the nose clip. Although less common, mask elastic bands have also been reported to be a potential source of ACD, with rubber accelerators being identified as potential allergens. However, there is often a lack of declaration of such chemicals used in the production of PPE. Given the need for continued use in the occupational setting, early identification and avoidance of allergens are key. Failure to do so may result in the progression of skin lesions, ultimately affecting the patients' quality of life and work performance. With the ubiquitous use of masks in the current climate, we wish to highlight the need for greater awareness of rubber accelerators as potential allergens, and their presence in the elastic bands of frequently used PPE.
ABSTRACT
Background: To date, over 10 million doses of mRNA vaccines (BNT162b2 mRNA and mRNA-1273) have been administered in Singapore. Initial studies have shown that 0.8% of individuals who received Moderna mRNA vaccine developed delayed injection-site reactions. Reactions to the Moderna mRNA vaccine are thought to be benign and not a contraindication to further doses. Injection-site reactions associated with the Pfizer-BioNTech mRNA vaccine are less clearly defined. We report the characteristics of mRNA COVID-19 injection-site reactions, comparing the clinical features between Moderna (mRNA-1273) and Pfizer-BioNTech (BNT162b2) reactions in the Singaporean adult population. Method(s): We retrospectively reviewed patients referred to the Dermatology Service / Allergy Centre of a tertiary hospital in Singapore for reactions post COVID-19 vaccination between 10 Jan 2021 and 26 Aug 2021. Inclusion criteria were adult patients who developed a localised injection-site reaction after either Moderna or Pfizer-BioNTech mRNA COVID-19 vaccination. Result(s): 322 patients were referred for post-COVID- 19 vaccine reactions, of which 21 developed injection-site reactions. 11 (52%) had received the Moderna mRNA vaccine while 10 (48%) received the Pfizer-BioNTech mRNA vaccine. Patients receiving the Moderna mRNA vaccine had a longer mean latency period (p = 0.047) and were more likely to have a latency duration of > 5 days (p = 0.007). Secondary dissemination of the injection-site reaction was seen in 2 patients. 11 (52%) of these reactions resolved without treatment;while the remaining 10 (48%) required symptomatic treatment with topical corticosteroids, antihistamines, or a combination of both. All 21 patients subsequently received the second vaccine dose, of which 2 (9.5%) developed recurrence of the reaction;both of which were mild and did not require treatment. Conclusion(s): Localised injection-site reactions post Moderna or Pfizer-BioNTech mRNA COVID-19 vaccination are uncommon and appear to be phenotypically different. Such reactions are benign and self-limited. While recurrence of the reaction can arise during repeat vaccine doses, these are mild and self-limited.
ABSTRACT
Background: Allergic rhinitis, one of the most common chronic allergic diseases, commonly associated with asthma, has a disease modifying therapy, allergen-specific immunotherapy (AIT). AIT can play a significant role in the reduction of clinical and immunological reaction to the culprit allergen, decreasing the onset of new sensitizations, preventing the onset of asthma, and reducing use of pharmacological treatments. This latter aspect is highly relevant for adolescents, a category of patients that frequently prefer to use "as few drugs as possible". AIT continuation may be difficult in some situations, such as the COVID-19 pandemic. Difficulty in accessing hospitals was experienced by many leading to a discontinuation of therapies for chronic conditions, such as allergic rhinitis. Method(s): We report our experience on the management, safety and adherence to sublingual immunotherapy (SLIT) prescribed to 25 adolescents affected by allergic rhinitis (house dust mite (HDM) -8 patients, SLIT grass pollen -12 patients, SLIT parietaria -5 patients), during the COVID-19 pandemic, following EAACI recommendations. The first administration of SLIT was carried out under medical supervision. We used a personalized monitoring approach according to the type of SLIT prescribed and according to the needs presented by each patient, advising them how to recognize and manage a possible reaction. Result(s): No immediate severe adverse reactions were reported by patients. Between the 2nd and 5th day of SLIT, 4 patients in therapy with HDM SLIT, experienced an exacerbation of rhinitis symptoms, with resolution after the use of oral antihistamine and topical cortisone+antihistamine before taking the daily dose of SLIT (for 30 days). Two patients on grass pollen SLIT and 2 patients on HDM SLIT, with gastric upset after taking SLIT daily while fasting, presented a resolution of the symptom after we advised them to take the daily dose in the morning after breakfast. Five patients interrupted SLIT for COVID-19 infection, until complete resolution. To date, all 25 patients are continuing SLIT, with good tolerability, with an improvement of rhinitis symptoms. Conclusion(s): We have reported real-life SLIT adherence and safety in adolescents that started SLIT during the COVID-19 pandemic to confirm how SLIT is a winning strategy and the only modifying treatment for allergic conditions.
ABSTRACT
Outcomes: 1. Describe unique barriers that Chinese North American patients with advanced cancer face in expressing emotions and discussing future planning. 2. Identify empathic opportunities (ie, topics associated with emotional expression) during care planning discussions with Chinese North American patients. Introduction: Recognizing emotions in intercultural contexts represents a core competency in palliative care. Yet, a paucity of literature describes the types, patterns, and contexts of patient-expressed emotions during high-stakes conversations with patients from linguistically marginalized communities. We sought to address this gap by analyzing the emotional content during care planning conversations with Chinese patients with advanced cancer and their caregivers. Method(s): We conducted a secondary analysis of 22 semistructured interviews of Chinese patients (n=20) with metastatic cancer and their caregivers (n=8) recruited at one American comprehensive cancer centre. Informed by the Empathic Communication Coding System and existing literature, we conducted template analysis to code the transcripts for patients' and caregivers' expressed emotions. We also thematically analyzed the patterns and contexts in which emotions arose. Result(s): Participants were middle-aged (55.6+/-13.5 years), born in China (89.3%), 60.7% female, 85.7% partnered/married, and 89.3% college educated. Most of the interviews were conducted with patients alone (72.7%). Happiness was the most prevalent emotion (62%) followed by gratitude (43%), fear (43%), sadness (38%), anger (14%), surprise (14%), and humour (5%). When a caregiver was present, the interviews trended toward lower frequency of emotional expression. Regarding intensity, only one instance (anger) was categorized as most severe. Regarding context, emotions were only expressed in discussions about the past or present. Specifically, participants expressed positive emotions when discussing clinician attributes, symptom relief, and immigration to North America. Participants expressed negative emotions when discussing burdensome symptoms, diagnostic journey, the COVID-19 pandemic, and experiences with linguistic or cultural discordance. Discussion(s): Emotional expression during high-stakes care planning conversations with Chinese patients and caregivers may be infrequent and grounded in social, topical, and temporal context. Future work is necessary to understand how clinicians could best respond to distressing emotions during naturally occurring palliative care conversations with Chinese patients and their caregivers.Copyright © 2023
ABSTRACT
Purpose: Between 2008 and 2014 approximately 32.5 million adults in the United States reported a diagnosis of osteoarthritis (OA). The 2019 American College of Rheumatology/Arthritis Foundation Guideline for the Management of Osteoarthritis (OA) of the hand, hip and knee recommend treating pain due to OA with analgesic therapy as part of multi-modal treatment program. A national survey conducted by the Centers for Disease Control found that patients with OA were likely to delay care during the pandemic. Given this new barrier to healthcare, access to analgesic therapy may have become even more limited. This study aimed to evaluate changes in analgesic prescribing practices for OA as a result of the COVID-19 pandemic. Method(s): A retrospective analysis was performed to identify new prescriptions, number of doses per order and refills of 73 topical and oral analgesics from encounters for OA. OA encounters were identified using 206 ICD-10 codes for OA from July 2019 to June 2021 at UC Davis Hospital and affiliated outpatient centers. Pre-pandemic data corresponds to 2019 data and data collected after this occurred during the pandemic. Counts of new prescriptions, number of doses per order and refills by fiscal quarter were analyzed using a two-factor Poisson Regression with an interaction between quarter and year with corresponding contrasts to detect a difference between 2019 and 2020 as well as 2019 and 2021 and quarters between these years. A follow-up Sidak step-down p-value adjustment was used to correct for type I error. All statistical analyses were done with a two-sided alpha of 0.05. The Poisson Regression was performed with SAS software for Windows version 9.4 (SAS Institute Inc., Cary, NC). Result(s): A total of 31,532 encounters with a primary diagnosis of OA occurred from July 2019 to June 2021. There was an increase in the number encounters with a primary diagnosis of OA (Figure 1) but there was no statistical difference in the medications ordered from 2019 to 2020, 2019 to 2021, and the quarters between these years as well. After adjusting for Type I error, there was a significant decrease in medication refills from 2019 to 2020 (p-value 0.0031, adjusted p-value 0.0425) as well as from 2019 to 2021 (p-value <0.0001, adjusted p-value 0.003) (Figure 2), and there was a significant decrease in number of doses of analgesia from 2019 to 2020 and an increase in number of doses from 2019 to 2021 (p-value <0.0001, adjusted p-value 0.003) (Figure 3). Conclusion(s): The COVID-19 pandemic has persistent impacts on the prescribing practices of analgesics for the treatment of OA. Our data suggests that since the COVID-19 pandemic, patients with OA were overall provided with more doses of analgesics and fewer refills. It is likely that barriers imposed by COVID-19 resulted in these changes in the way analgesics are provided for the treatment of OA.

ABSTRACT
A 51-year-old woman presented to our service with a 2-year history of severely painful, thickened skin of her bilateral hands and feet. She advised of considerable skin pain on mobilizing. She intermittently applied acrylate nails. This was on a background of chronic urticaria, asthma and allergic rhinitis. She described a positive family history of psoriasis. On examination, there was marked hyperkeratosis with welldemarcated erythema on the central palms and entire fingers with deep fissuring and scale. Similar finding were noted on the soles of the feet particularly affecting the heels, arch and also the tips of the toes. The morphology of the lesions favoured psoriasis, but the differential diagnosis included chronic hand dermatitis. She was referred for topical psoralen + ultraviolet A (PUVA) and patch testing to standard battery and acrylates. Treatment with topical PUVA was discontinued and patch testing lists were cancelled as a result of the emergence of COVID-19 in Ireland. Topical therapy of clobetasol propionate was initiated. On follow-up review, the appearances of her feet and hands had deteriorated significantly. She was commenced on acitretin 10 mg once daily, which was escalated to 20 mg 2 months later. Clinical improvement was noted, but appearances deteriorated once again following the application of acrylic nails. Further history revealed the patient had assisted with the application of acrylic nails to clients years prior to her initial review. Patch testing took place 18 months after initial review due to outpatient list cancellations secondary to the COVID-19 pandemic. Upon review 48 h after the application of the (METH) Acrylate Series, the patient was found to have a +2 reaction to 2- hydroxyethyl methacrylate and a further +2 reaction to 2- Hydroxypropyl methacrylate. At her 96-h review, both reaction sites were marked at +1. Following complete avoidance of acrylates, the palmoplantar inflammation entirely resolved. This case highlights the importance of a detailed clinical history where contact dermatitis is considered. In our patient's case, the clinical history and examination of the palmoplantar eruption combined with the first-degree family history of psoriasis were highly suggestive of a diagnosis of psoriasis. The episodic severe flares and its refractory nature to treatment raised suspicion for allergic contact dermatitis. Dermatologists should remain alert for potential contact allergens in cases of severe palmoplantar psoriasis. A further area for consideration is the deleterious effect the COVID-19 pandemic had on the successful diagnosis and treatment of dermatological patients through the cancellation of outpatient services.
ABSTRACT
5-Fluorouracil (Efudix) cream is established as a topical treatment for superficial malignant and premalignant skin lesions. Its method of action involves the irreversible binding of the pyrimidine analogue fluorouracil to thymidylate synthetase within a cell. This prevents the incorporation of uracil into nuclear RNA, which destroys abnormal cancer cells (https://dermnetnz.org/topics/5-fluorouracil-cream). The expected sequelae of its use involves the development of a marked inflammatory response. We present a case of a severe, disproportionate reaction to Efudix cream, secondary to contact allergy to the excipients. A 61-year-old man attended the cutaneous allergy clinic with a history of severe, florid, inflammatory and ulcerative skin reactions affecting the lower limbs at sites of application of Efudix cream. This had been used as directed, to treat areas of Bowen disease, at intervals between December 2019 and February 2021. Contact allergy to Efudix cream was suspected and patch testing was performed to the British Standard and Cosmetic series, as well as the excipients of Efudix cream, including stearyl alcohol, propylene glycol (PG), methylparahydroxybenzoate, propylparahydroxybenzoate and white soft paraffin. While the patch tests were applied in the department on day 0, subsequent appointments on days 2, 4 and 7 were performed virtually with photographs as the patient developed COVID-19 symptoms, with positive lateral flow and polymerase chain reaction tests. He was patch test positive on days 4 and 7 to stearyl alcohol and propylene glycol, both being excipients of Efudix cream. A review of our database over a period of 17 years revealed 53 other cases with positive patch test to PG (n = 53/8000;0.66%), none of which were attributable to the use of Efudix cream, and only six cases of a positive patch test to stearyl alcohol (n = 6/8000;0.075%), of which one was attributable to the use of Efudix cream. Allergic contact dermatitis to Efudix cream and its excipients stearyl alcohol and propylene glycol is rare, although it has previously been described in the literature with the earliest reports in 1992, and the most recent being 15 years ago [Meijer B, de Waardvan der Spek F. Allergic contact dermatitis because of topical use of 5-fluorouracil (Efudix cream). Contact Dermatitis 2007;57: 58-60]. This case adds to the existing literature and is a reminder to clinicians that, although inflammation is expected with the use of Efudix cream, severe or disproportionate reactions should raise suspicion of possible contact allergy. Furthermore, this case highlights the challenges of patch testing in the current COVID-19 climate and highlights the importance of teledermatology as a novel option for assessment in cutaneous allergy services facing these conditions.
