Use of 5% lidocaine patch in the management of post-traumatic localized neuropathic pain. Case reports
(2023) LIGGIERI, André; MINSON, Fabíola
ABSTRACT BACKGROUND AND OBJECTIVES: Neuropathic pain is defined as a pain caused by a lesion or condition that affects the somatosensory nervous system. Taking its prevalence into account, in particular post-traumatic localized neuropathic pain, and to discuss ways to manage patients with this condition, considering efficacy and tolerability of proposed treatments, this report presents three clinical cases of patients with post-traumatic localized neuropathic pain treated with 5% lidocaine transdermal patch in both monotherapy and polytherapy. CASE REPORTS: This study reports the cases of three female patients aged between 29 and 81 years with complaints of pain due to trauma, who were managed with 5% lidocaine transdermal patch in prolonged treatment, with a significant improvement in pain. CONCLUSION: According to scientific evidence, the use of 5% lidocaine transdermal patch in post-traumatic localized neuropathic pain as shown efficacy with favorable safety and tolerance. Moreover, it was possible to demonstrate that a 5% lidocaine transdermal patch in a polytherapy format has contributed to improved outcomes with no effect in treatment tolerability.

Dermatofibrossarcoma na glabela: Uma localização incomum
(2023) BALDINI, CARLOS EDUARDO; CASTRO, MARIO AUGUSTO FERRARI DE; DEDIVITIS, ROGéRIO APARECIDO
ABSTRACT Dermatofibrosarcoma is a rare cancer with a slow growth pattern and aggressive tissue invasion. The treatment for this condition involves surgical intervention to achieve clear margins. In this particular case, we have a 60-year-old man who had a mass in the glabella area that was excised twice under local anesthesia at a different facility. The results of both biopsies indicated dermatofibroma. However, the patient experienced a new recurrence, and during the immunohistochemistry analysis of the initial excision, it was revealed to be dermatofibrosarcoma. As a result, a broad excision was performed until negative margins were obtained based on frozen sections. Additionally, a frontal flap was employed to reconstruct the surgical defect. The outcome of the treatment was deemed successful, without complications.

Lidocaine 5% patch in the treatment of localized neuropathic pain due to nerve compression. Case reports
(2023) LIGGIERI, André; PALLADINI, Mariana
ABSTRACT BACKGROUND AND OBJECTIVES: Neuropathic pain is a chronic condition with a significant burden for patients, society, and healthcare systems. Due to neuropathic complexity, its management must be different than the one for nociceptive pain. First-line systemic treatments may be associated with dose-dependent adverse events and drug-drug interactions. On the other hand, topical treatments have less systemic adverse events, with the 5% lidocaine transdermal patch being recommended for firstor second line of treatment for neuropathic pain according to various international guidelines. The aim of this study is to present three cases of localized neuropathic pain due to nerve compression managed with 5% lidocaine transdermal patch. CASE REPORTS: The cases of three adult patients (>40 years old) with pain or tingling for a long period of time and their outcomes with treatment with 5% lidocaine transdermal patch for a prolonged duration were investigated. All three cases report a significant improvement in pain. CONCLUSION: The results of the reported cases revealed that a 5% lidocaine transdermal patch represents an effective, safe and tolerable and noninvasive option for the management of localized neuropathic pain due to peripheric nerve compression.

Tapentadol extended-release as a therapeutic strategy for pain control in cases of osteoarthritis. Case reports
(2023) MORAES, Frederico Barra de; LIGGIERI, André Cicone; SADIGURSKY, David
ABSTRACT BACKGROUND AND OBJECTIVES: Osteoarthritis affects many individuals worldwide and is caused by multiple factors that lead to joint wear and tear, inflammation and, consequently, chronic pain that is difficult to treat. It is predominant in seniors, but not restricted to older age groups. Pain reduction is prioritized when facing crises, so that rehabilitation work and postural corrections can be applied later. The present study aimed to evaluate the analgesic potential of tapentadol extended-release (ER) in three patients with osteoarthritis who had undergone numerous previous treatments and had a history of moderate to severe chronic pain. CASE REPORTS: Three women, aged 49, 75 and 86 years old, diagnosed with osteoarthritis, with complaints of severe pain and who had undergone numerous therapies including drug use, without significant pain control were included in the study. The use of tapentadol ER was recommended and adjusted to each patient according to the intensity of pain. All of them responded satisfactorily and returned to their daily activities. One of them presented nausea after two days of tapentadol use, which was controlled with an antiemetic drug only during the two days of nausea CONCLUSION: Tapentadol ER was effective in controlling pain from osteoarthritis in the three cases evaluated, without serious adverse effects. The period and dosage of tapentadol ER must be in accordance with the clinical evolution of each patient.

“Star of Bethlehem sign” in the analysis of the evolution of brain lesions during and after treatment for neuroparacoccidioidomycosis
(2023) SANTANA, Larissa M.; PEÇANHA, Paulo Mendes; FALQUETO, Aloísio; KRUSCHEWSKY, Wdson L. M.; GRÃO-VELLOSO, Tânia Regina; GONÇALVES, Sarah Santos; ROSA-JÚNIOR, Marcos
Abstract Objective: To describe the clinical and radiological evolution of lesions during and after treatment in patients diagnosed with neuroparacoccidioidomycosis (NPCM). Materials and Methods: This was a retrospective study of the medical records, computed tomography scans, and magnetic resonance imaging (MRI) scans of patients with NPCM treated between September 2013 and January 2022. Results: Of 36 cases of NPCM, eight were included in the study. One patient presented only with pachymeningeal and skull involvement, and seven presented with pseudotumors in the brain. Collectively, the eight patients presented with 52 lesions, of which 46 (88.5%) were supratentorial. There were 32 lesions with a diameter ≤ 1.2 cm, of which 27 (84.4%) disappeared during the treatment. In three cases, there were lesions > 1.2 cm that showed a characteristic pattern of evolution on MRI: an eccentric gadolinium contrast-enhanced nodule, with a subsequent decreased in the size and degree of contrast enhancement of the lesions. Conclusion: In NPCM, supratentorial lesions seem to predominate. Lesions ≤ 1.2 cm tend to disappear completely during treatment. Lesions > 1.2 cm tend to present with a similar pattern, designated the “Star of Bethlehem sign”, throughout treatment.
