ABSTRACT

OBJECTIVE: This analysis of the first-line cohort of LASER201 study evaluated the efficacy and safety of lazertinib 240 mg as a frontline therapy for epidermal growth factor receptor (EGFR)-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC). METHODS: A total of 43 patients, with EGFR mutation-positive (Exon19Del, n = 24; L858R, n = 18; G719X, n = 1) locally advanced or metastatic NSCLC who had not previously received EGFR tyrosine kinase inhibitor (EGFR TKI) therapy, received once-daily lazertinib 240 mg. EGFR mutation status was confirmed by local or central testing. The primary endpoint was objective response rate (ORR) assessed by blinded independent central review. Secondary efficacy endpoints included duration of response (DoR), disease control rate (DCR), progression-free survival (PFS), tumor shrinkage, and overall survival (OS). RESULTS: At the primary data cut-off (DCO; January 8, 2021), the ORR was 70 % (95 % confidence interval [CI]: 56.0-83.5), DCR was 86 % (95 % CI: 75.7-96.4) and the median DoR was 23.5 (95 % CI: 12.5-not reached) months. The median PFS was 24.6 (95 % CI: 12.2-30.2) months. At the final DCO (March 30, 2023), the median OS was not estimable and the median follow-up duration for OS was 55.2 [95 % CI: 22.8-55.7] months. OS rates at 36 months and 54 months were 66 % (95 % CI: 47.5-79.3 %) and 55 % (95 % CI: 36.6-70.7 %), respectively. The most commonly reported TEAEs were rash (54 %), diarrhea (47 %), pruritus (35 %), and paresthesia (35 %). No drug-related rash or pruritus TEAEs of grade 3 or higher were reported. Diarrhea and paresthesia of grade 3 or higher were reported in 3 (7 %) and 1 (2 %) patients, respectively. CONCLUSION: This analysis demonstrated long-term clinical benefit with lazertinib 240 mg in patients with EGFR-mutated NSCLC who had not previously received EGFR TKIs. The safety profile for lazertinib was tolerable and consistent with that previously reported.

ABSTRACT

BACKGROUND: Leprosy is rare within non-endemic countries such as Canada, where cases are almost exclusively imported from endemic regions, often presenting after an incubation period of as many as 20 years. Due to its rarity and prolonged incubation period, diagnosis is often delayed, which may result in neurologic impairment prior to the initiation of treatment. In this report we describe a case that is novel in its incubation period, which is the longest reported to-date and may have contributed to diagnostic delay. The case also uniquely demonstrates the challenges of distinguishing leprosy reactions from new rheumatologic manifestations in a patient with established autoimmune disease. CASE PRESENTATION: We describe an 84-year-old male patient with rheumatoid arthritis on methotrexate and hydroxychloroquine, with no travel history outside Canada for 56 years, who presented in 2019 with new-onset paresthesias and rash. His paresthesias persisted despite a short course of prednisone, and his rash recurred after initial improvement. He underwent skin biopsy in May 2021, which eventually led to the diagnosis of leprosy. He was diagnosed with type 1 reaction and was started on rifampin, dapsone, clofazimine and prednisone, with which his rash resolved but his neurologic impairment remained. CONCLUSION: This case report serves to highlight the potential for leprosy to present after markedly prolonged incubation periods. This is especially relevant in non-endemic countries that is home to an aging demographic of individuals who migrated decades ago from endemic countries. The importance of this concept is emphasized by the persistent neurologic impairment suffered by our case due to untreated type 1 reaction. We also demonstrate the necessity of skin biopsy in distinguishing this diagnosis from other autoimmune mimics in a patient with known autoimmune disease.

ABSTRACT

PURPOSE: To evaluate the recurrence rate of odontogenic keratocyst (OKC) after treatment with 5-fluoracil as an adjunctive therapy and to evaluate, as well, the efficacy of this medication in reducing the incidence of inferior alveolar nerve paresthesia associated with other chemotherapeutic agents. MATERIAL AND METHODS: The research question (developed according to the patient/population, intervention, comparison, and outcomes [PICO] method) addressed was "Does the use of 5-fluorouracil as an adjunctive therapy in the treatment of OKC reduce both the recurrence rate and the incidence of inferior alveolar nerve paresthesia as compared with other chemotherapeutic agents?" A systematic review was performed by searching 4 databases: PubMed, EBSCO, Portal Evidencia, and Cochrane Reviews. Each search was conducted twice. Two independent reviewers evaluated the data. For each database, a search strategy was developed that included the following generic terms: Fluorouracil, 5-Fluorouracil, or liquid nitrogen and odontogenic cyst or odontogenic keratocyst. Three filters were applied to the searches, as well, consisting of the terms clinical trials, English papers, and Spanish papers. RESULTS: Of the 74 papers retrieved. The titles and abstracts of the selected papers were reviewed to determine whether those papers were relevant to our research question; only 3 papers were selected for this systematic review: 2 retrospective cohort studies and 1 clinical trial. Assessments risk bias and the quality of evidence were performed. CONCLUSIONS: The risk of bias and quality of evidence in this systematic review are moderate due to the study's design, although the clinical results were excellent with respect to the reduction of both OKC recurrence and paresthesia associated with this kind of cyst.

ABSTRACT

Background: 'White-cord syndrome' is an extremely rare entity following decompression of cervical cord in which post-operative reperfusion injury results in worsening of patient's neurology and MRI reveals signal changes in spinal cord in absence of cord compression. We wish to report a case of 'white-cord syndrome' following a 'routine' ACDF. Case Description: A 39-year-old woman with paresthesias and spastic quadriparesis was found to have C5-C6 PIVD on MRI. ACDF was performed at C5-C6, after which worsening of quadriparesis was noted, for which intravenous high-dose steroids were started. An urgent MRI was done, which revealed findings of white-cord syndrome, without compression on underlying cord. With conservative management, her ASIA grade improved from C to D and the features of white-cord syndrome disappeared on follow-up imaging. Conclusion: It is important for surgeons and patients to be aware of this rare but potentially catastrophic entity as this needs to be discussed while taking consent for surgery.

ABSTRACT

Notalgia paresthetica (NP) is a sensory neuropathy characterized by chronic, localized pruritus in a circumscribed area on the upper back. Pruritus, frequently resistant to treatment, may be accompanied by pain, paresthesia, allodynia and alloknesis. There is a paucity of data in the NP literature about the use of lidocaine 5% medicated plaster. This case involves a 75-year-old woman with NP and a history of many unsuccessful local or systemic treatments. The patient was treated with lidocaine 5% medicated plaster, while other therapies were progressively retired. After 11 weeks of therapy, a significant reduction in the intensity of itching was achieved and the itching area was reduced. The patient also reported an associated improvement in her quality-of-life throughout therapy. In conclusion, lidocaine 5% medicated plaster was successful in relieving itching and other symptoms in this case of NP.


Notalgia paresthetica (NP) is a nerve disorder characterized by itching on the upper back. Sometimes the itch is so painful and intense that it can make it difficult to sleep, work and socialize, affecting quality-of-life. There are different treatments for NP and not everyone will have the same response to treatment. In this case, a woman with long-standing NP, after several unsuccessful therapies, were treated with lidocaine 5% medicated plaster, which can be applied to the skin where it hurts. After 11 weeks of therapy, an important reduction in the intensity of itching was achieved and the itching area was reduced. The patient also reported an improvement in her quality-of-life throughout therapy. In conclusion, lidocaine 5% medicated plaster was successful in relieving severe itch in this NP case.

ABSTRACT

INTRODUCTION: Oxaliplatin is a platinum containing alkylating agent commonly used in the management of colorectal cancers. The most common dose-limiting toxicity of oxaliplatin is peripheral neuropathy, which can be severe enough to cause treatment discontinuation. We present a case of dysarthria and laryngopharyngeal dysesthesia (LPD) that developed during the first dose of oxaliplatin, which showed dose-dependent reduction in severity in subsequent cycles. CASE REPORT: A 52-year-old female patient with adenocarcinoma of rectum (pT4N2M0) was prescribed oxaliplatin (130 mg/m2) and capecitabine(2000mg/m2). She developed heaviness in the tongue, slurred speech, jaw pain, perioral paresthesia within 30 min after the end of 3 h infusion of oxaliplatin in the first cycle. The symptoms subsided without any sequelae in two days. However, in the subsequent cycles as the dose of the oxaliplatin was reduced, similar symptoms reappeared but were of reduced in severity. No dysesthesia symptoms were observed in the 4th cycle when the oxaliplatin was administered at 85 mg/m2. MANAGEMENT AND OUTCOME: As and when the patient developed symptoms - slurred speech, jaw pain during the first three cycles, she was managed with inj. Hydrocortisone (100 mg i.v.) and one ampoule of pheniramine (45 mg i.v.). DISCUSSION: Occurrence of laryngopharyngeal dysesthesia due to oxaliplatin does not warrant drug withdrawal, dose titration can be helpful, thereby preventing the drug withdrawal for the patient management.

ABSTRACT

INTRODUCTION: Vortioxetine, a multimodal serotonergic drug, is widely used as treatment for major depressive disorder. Although on the market since late 2013, the data of the relative safety of vortioxetine, especially compared to selective serotonin reuptake inhibitors, are still scarce. OBJECTIVE: The aim of this study was to explore the adverse event reporting pattern of vortioxetine through a cluster analysis. Furthermore, to compare the adverse event reporting pattern for vortioxetine with that of the selective serotonin reuptake inhibitors. METHODS: Individual case safety reports for vortioxetine in VigiBase up to 1 November, 2019 were subjected to consensus clustering, to identify and describe natural groupings of reports based on their reported adverse events. A vigiPoint exploratory analysis compared vortioxetine to the selective serotonin reuptake inhibitors in terms of relative frequencies for a wide range of covariates, including patient sex and age, reported drugs and adverse events, and reporting country. Important differences were identified using odds ratios with adaptive statistical shrinkage. RESULTS: Thirty-six clusters containing at least five reports were identified and analysed. The two largest clusters included 48% of the vortioxetine reports and appeared to represent gastrointestinal adverse events and hypersensitivity adverse events. Other distinct clusters were related to, respectively, fatigue, aggression/suicidality, convulsion, medication errors, arthralgia/myalgia, increased weight, paraesthesia and anticholinergic effects. Some of these clusters are not labelled for vortioxetine, such as arthralgia/myalgia and paraesthesia, but are known adverse events for selective serotonin reuptake inhibitors. A vigiPoint analysis revealed a higher proportion of reports from consumers and non-health professionals for vortioxetine as well as higher relative reporting rates of gastrointestinal symptoms, pruritus and mood-related symptoms, consistent with the cluster analysis. CONCLUSIONS: A pattern of co-reported adverse events that is consistent with labelled adverse events for vortioxetine and the safety profile for selective serotonin reuptake inhibitors in general was revealed. Clusters of unlabelled adverse events were identified that reflect clinical entities that might represent signals of previously unknown adverse events. More extensive analyses of spontaneous reports may help to further understand the reporting pattern of adverse events.

ABSTRACT

RATIONALE: Systemic lupus erythematosus (SLE) is a complex autoimmune inflammatory disease that frequently affects various organs. Neuropsychiatric manifestations in SLE patients, known as neuropsychiatric SLE, are clinically common. However, the principal manifestation of cranial neuropathy in patients with SLE and comorbidities is relatively rare. PATIENT CONCERNS: In this report, we describe a 51-year-old Chinese woman who was admitted with a chief complaint of chronic-onset facial paresthesia, dysphagia, and choking cough when drinking water, accompanied by slurred speech, salivation, and limb weakness. The blood autoantibody test results showed that many SLE-associated antibodies were positive. Meanwhile, anti-nuclear matrix protein 2 (NXP2) antibody was strongly positive in the idiopathic inflammatory myopathy (IIM) spectrum test from the serum. Muscle biopsy indicated inflammatory infiltration of the muscle fiber stroma. DIAGNOSES: Taking into account the clinical manifestations and laboratory tests of the present case, the diagnosis of SLE and probable IIM was established. INTERVENTIONS: Corticosteroids and additional gamma globulin were administered and the clinical symptoms were relieved during the treatment process. OUTCOMES: Unfortunately, the patient experienced sudden cardiac and respiratory arrest. Multiple system dysfunctions exacerbated disease progression, but in the present case, we speculated that myocardial damage resulting from SLE could explain why she suddenly died. LESSONS: To our knowledge, multiple neurological manifestations in patients with SLE and anti-NXP2-positive myositis are rare. Note that SLE is still a life-threatening disease that causes multiple system dysfunctions, which requires increasing attention.

ABSTRACT

INTRODUCTION: Few of the 5000-8000 snakebites reported to poison control centers annually in the USA are attributed to coral snakes. This study describes Texas coral snake envenomations reported to the North American Snakebite Registry. METHODS: All Texas coral snake envenomation cases reported to the registry were identified for the period from January 1, 2015, through December 31, 2019. Data reviewed for this study included details regarding the snake encounter, patient demographics, signs and symptoms, treatment, and outcomes. Descriptive statistics were used to report results. RESULTS: Ten men and four nonpregnant women reported coral snake bites. The median patient age was 15.5 (range 5-72 years). There were 12 upper extremity bites and two bites to the lower extremity. The most common symptoms reported were paresthesias and pain. All subjects had paresthesias, often described as an "electric" sensation. Seven patients described them as painful. The most common clinical findings were erythema and swelling. No patient developed tissue damage, hematotoxicity, rhabdomyolysis, hypotension, weakness, or respiratory symptoms. Thirteen subjects were treated with opioids. Six patients were treated with antiemetics: three prophylactically and two for opioid-induced nausea. One patient developed nausea and non-bloody, nonbilious emesis within 1 hour of the bite, prior to receiving opioids. No patients were treated with antivenom. Antibiotics were not administered to any patient, and no infections were reported. CONCLUSIONS: Envenomations from M. tener in Southeast Texas are characterized by painful paresthesias. Mild swelling and erythema are common. Neurotoxicity necessitating antivenom or mechanical ventilation did not occur.

ABSTRACT

Palmar plantar erythrodysesthesia (PPE) is a commonly reported skin toxicity of chemotherapeutic agents that significantly affects patients' quality of life. PPE is described as inflammation, swelling, and even cracks and ulcers in the skin of palms and soles of the feet. Conventional treatment includes topical creams, analgesics, or corticosteroids. However, serious cases are not responding to these medications. PPE has been reported to cause drug cessation or dose reduction if not properly treated. Sildenafil citrate (SC) has a well-documented activity in wound healing through improving blood supply to the affected area. However, SC has poor physicochemical properties limiting its transdermal permeation and deposition. This research endeavored to elaborate novel vesicular system with natural components, phospholipids and oleic acid, loaded with sildenafil citrate for topical management of PPE. Sildenafil-loaded oleosomes were prepared using modified ethanol injection method. Optimized oleosomes had nanometric particle size (157.6 nm), negative zeta potential (- 85.2 mv), and high entrapment efficiency (95.56%). Ex vivo studies on human skin revealed that oleosomes displayed 2.3-folds higher permeation and 4.5-folds more deposition through the human skin compared to drug suspension. Results endorsed SC oleosomes as suitable topical treatment of PPE providing ameliorated sildenafil permeability in addition to acting as a reservoir for gradual release of the drug.

ABSTRACT

CANOMAD (chronic ataxic neuropathy, ophthalmoplegia, immunoglobulin M [IgM] paraprotein, cold agglutinins, and disialosyl antibodies) is a rare syndrome characterized by chronic neuropathy with sensory ataxia, ocular, and/or bulbar motor weakness in the presence of a monoclonal IgM reacting against gangliosides containing disialosyl epitopes. Data regarding associated hematologic malignancies and effective therapies in CANOMAD are scarce. We conducted a French multicenter retrospective study that included 45 patients with serum IgM antibodies reacting against disialosyl epitopes in the context of evocating neurologic symptoms. The main clinical features were sensitive symptoms (ataxia, paresthesia, hypoesthesia; n = 45, 100%), motor weakness (n = 18, 40%), ophthalmoplegia (n = 20, 45%), and bulbar symptoms (n = 6, 13%). Forty-five percent of the cohort had moderate to severe disability (modified Rankin score, 3-5). Cold agglutinins were identified in 15 (34%) patients. Electrophysiologic studies showed a demyelinating or axonal pattern in, respectively, 60% and 27% of cases. All patients had serum monoclonal IgM gammopathy (median, 2.6 g/L; range, 0.1-40 g/L). Overt hematologic malignancies were diagnosed in 16 patients (36%), with the most frequent being Waldenström macroglobulinemia (n = 9, 20%). Forty-one patients (91%) required treatment of CANOMAD. Intravenous immunoglobulins (IVIg) and rituximab-based regimens were the most effective therapies with, respectively, 53% and 52% of partial or better clinical responses. Corticosteroids and immunosuppressive drugs were largely ineffective. Although more studies are warranted to better define the optimal therapeutic sequence, IVIg should be proposed as the standard of care for first-line treatment and rituximab-based regimens for second-line treatment. These compiled data argue for CANOMAD to be included in neurologic monoclonal gammopathy of clinical significance.

ABSTRACT

La notalgia parestésica es una mononeuropatía sensitiva por atrapamiento localizada a nivel dorsal. Clínicamente se caracteriza por la presencia de prurito, parestesias y/o hiperalgesia asociados a placas hiperpigmentadas en el dermatoma correspondiente, que genera un gran impacto en la calidad de vida del paciente. Presentamos dos pacientes de entre 35 y 65 años con sintomatología crónica tratados en nuestro servicio mediante infiltraciones subcutáneas de toxina botulínica tipo A en las áreas afectadas. Observamos una disminución de la escala EVA de dolor y de la intensidad del prurito tras la infiltración, así como una disminución de la placa hiperpigmentada al mes, a los tres y a los seis meses y que se mantiene al año. Concluimos que el tratamiento con toxina botulínica tipo A podría ser una alternativa segura y útil en estos pacientes, ya que en nuestro estudio ha demostrado ser eficaz a más largo plazo que los tratamientos disponibles hasta la actualidad, aunque se necesitan más estudios con pacientes para confirmarlo

ABSTRACT

BACKGROUND/OBJECTIVE: Notalgia paresthetica (NP) is a sensory neuropathy characterized by localized pruritus and pain, presenting with or without a well-circumscribed hyperpigmented patch in the upper back. Abnormal sensations, such as burning, numbness, and paresthesia are often present in patients with NP. In this study, we clinically and radiologically analyzed patients with NP. The literature contains studies describing lidocaine treatments involving intravenous and topical applications for NP. We also investigated the effect of intradermal lidocaine injection on patients with NP. METHODS: A total of 80 patients (45 patients with NP and 35 suffering from dorsalgia without NP) were included in the study. The age, gender and body mass index (BMI) of the patients, and the characteristics of their symptoms were recorded. The severity of pain and pruritus was assessed by the Visual Analog Scale (VAS). Radiography and magnetic resonance imaging of the spine were performed. In this study, we intradermally administered lidocaine diluted with saline into the upper back over three sessions. 1 cc 2% lidocaine was diluted with 5 cc 0.9% saline, and a total of 6 cc lidocaine mixture was obtained. The injection was performed locally at 1-cm intervals around the hyperpigmented patch and segmentally along the C2-T6 spinous processes. These patients were called for a follow-up at the second and fourth weeks and third month. RESULTS: There was no statistically significant difference between the two groups in terms of age, BMI, VAS-pain score, and duration of symptoms (p > 0.05 for all). Forty-six cervical and/or thoracic degenerative changes or herniated nucleus pulposus (HNP) were detected in patients with NP. There was a significantly higher number of HNP at the C6-7 segment and cervical degenerative changes in the NP group (p < 0.05). The VAS-pain and VAS-pruritus scores were significantly decreased at all follow-up sessions, and improvement was sustained by lidocaine up to the third month. CONCLUSION: Cervical degenerative changes and HNP of the C6-7 segment seem to be contributing factors for NP. Local lidocaine can be effective for pain relief and pruritus in NP.

ABSTRACT

BACKGROUND Numb chin syndrome is a rare and under diagnosed neuropathy of the inferior alveolar branch of the trigeminal nerve usually causing a lower lip and chin anesthesia or paresthesia. The syndrome is commonly associated with broad-spectrum malignant and non-malignant conditions. CASE REPORT Here we report a case of a 30-year-old male who presented with numb chin syndrome in the form of jaw pain, paresthesia, and hypoesthesia of the mental area as the presenting symptoms of acute of myeloid leukemia with t(8;21) treated with (3+7) protocol (3 days anthracycline+7 days cytarabine). The pain and paresthesia improved but hypothesia persisted. CONCLUSIONS Acute myeloid leukemia is one of the most serious causes of numb chin syndrome which should not be overlooked.

ABSTRACT

Background: Notalgia paresthetica (NP) is a sensory neuropathy of the back characterized by a well demarcated, hyperpigmented macule or patch located medial or inferior to the scapulae. Symptoms include localized pruritus and pain, and the clinical course consists of remissions and relapses. It can be an underrecognized and difficult disease to treat since conventional treatments for pruritus in inflammatory dermatosis have variable efficacy. There are a variety of treatment modalities, but strong evidence to suggest the superiority of any one treatment is lacking.Objective: This review describes the treatments that have been used for NP in the literature and evaluates their level of evidence with respect to their efficacy. We also present a treatment algorithm based on our analysis.Materials and methods: MEDLINE search was performed using the terms 'notalgia,' 'paresthetica,' and 'treatment.' All resulting articles have been included in this review.Results: Treatment options include topical agents (capsaicin, tacrolimus, anesthetic cream, and amitriptyline/ketamine), systemic agents (gabapentin, oxcarbazepine, and amitriptyline), procedural modalities (botulinum toxin A and narrowband UVB), and physical therapy.Conclusions: Treatment should begin with topical agents or physical therapy, then systemic agents, and finally procedural modalities. We recommend combining treatment options with physical therapy for sustained treatment response.
