Emerging pharmacotherapy trends in preventing and managing oral mucositis induced by chemoradiotherapy and targeted agents.

INTRODUCTION: The introduction of targeted therapy and immunotherapy has tremendously changed the clinical outcomes and prognosis of cancer patients. Despite innovative pharmacological therapies and improved radiotherapy (RT) techniques, patients continue to suffer from side effects, of which oral mucositis (OM) is still the most impactful, especially for quality of life. AREAS COVERED: We provide an overview of current advances in cancer pharmacotherapy and RT, in relation to their potential to cause OM, and of the less explored and more recent literature reports related to the best management of OM. We have analyzed natural/antioxidant agents, probiotics, mucosal protectants and healing coadjuvants, pharmacotherapies, immunomodulatory and anticancer agents, photobiomodulation and the impact of technology. EXPERT OPINION: The discovery of more precise pathophysiologic mechanisms of CT and RT-induced OM has outlined that OM has a multifactorial origin, including direct effects, oxidative damage, upregulation of immunologic factors, and effects on oral flora. A persistent upregulated immune response, associated with factors related to patients' characteristics, may contribute to more severe and long-lasting OM. The goal is strategies to conjugate individual patient, disease, and therapy-related factors to guide OM prevention or treatment. Despite further high-quality research is warranted, the issue of prevention is paramount in future strategies.

Secondary Trigeminal Neuralgia: A Case Report and Literature Review of Red Flags.

Introduction: Trigeminal neuralgia (TN) is characterised by recurrent paroxysmal brief episodes of electric shock-like pain along the trigeminal nerve distribution. Based on the underlying cause, the current classification systems have classified TN into idiopathic, classical and secondary TN. This manuscript presents a case report of a patient seen in the clinic with features of TN secondary to an intracranial lesion. Case Description: A 39-year-old female presented to the clinic with a 15-month history of severe, intermittent, short-lasting episodes of pain affecting the left lower teeth, jaw, nose and temporal region. The patient reported familiar shock-like pain during the physical examination when the skin of the left ala of the nose was lightly touched. The rest of the clinical examination was non-significant. The magnetic resonance imaging (MRI) of the brain showed an approximately 20 mm wide lesion at the level of the left cerebellopontine angle. After subsequent tests, the lesion was diagnosed as meningioma, and the patient was treated with stereotactic radiation therapy. Practical Implications: In up to 10% of TN cases, the underlying cause can be due to a brain tumour. Although persistent pain, sensory or motor nerve dysfunction, gait disturbances and other neurological signs may concurrently exist, raising a red flag for intracranial pathology, patients often present with pain alone as the heralding symptom of a brain tumour. Due to this, it is imperative that all patients suspected of having TN undergo an MRI of the brain as part of the diagnostic work-up.

Malignancy rates in thyroid nodules classified as Bethesda categories III and IV; a subcontinent perspective.

BACKGROUND: Bethesda category III and IV thyroid nodules fall in the indeterminate risk of malignancy category. These nodules have been a relatively elusive entity to manage as previous studies have shown a wide variation in malignancy rates in different regions and institutions across the world. However, data from the subcontinent with regards to this is scarce. AIM AND OBJECTIVE: This study aimed to determine the characteristics and malignancy rates of cytology proven Bethesda Category III and IV thyroid nodules and its association with clinical, histopathological and laboratory variables, in the regional population. METHOD: A retrospective search was performed on all patients with thyroid nodules who presented to this hospital, from January 2011 to September 2018. Patients who had cytology proven Bethesda category III and IV thyroid nodules that underwent surgery were included in the study. RESULTS: Malignancy in Bethesda Category III and Bethesda Category IV thyroid nodules was 29.6% and 47.1%, respectively. There was no significant association determined between malignancy rate and various clinical, histopathological, and radiological characteristics. CONCLUSION: The malignancy rates in Bethesda category III and IV thyroid nodules in this study are significantly higher than that initially suggested by the Bethesda consensus publication but is comparable to international data present.

Improving Compliance of Physicians in Reporting and Documenting Critical Alerts in a Cancer Hospital.

Introduction: A critical result of an investigation is considered a representation of a pathophysiological state deemed to be high risk or life threatening for the patient. Therefore, such results should be addressed in an appropriate and timely manner. Unfortunately, routine closed chart audits suggested that the compliance of physicians in documenting critical alerts in patient notes was poor. This prompted the hospital to conduct a continuous quality improvement (CQI) project to improve the physicians' compliance. Materials and Methods: A cause-and-effect analysis was conducted using a fishbone diagram to identify the reasons for poor compliance. Based on the analysis, several modifications were made, including, but not limited to, hospital-wide educational sessions on the standard operating procedures of receiving and documenting critical alerts for the physicians, daily audit of critical alerts to review the appropriateness of documentation and introduction of a new module in the hospital electronic medical record to acknowledge and document receiving critical alerts. Results: Before implementing the strategies to improve physicians' documentation compliance, the average compliance rate was 57% in April 2020, and the median compliance rate was 52% (January 2020-April 2020). However, afterward, within a couple of months of implementing changes, the average compliance rate increased to 88%. This improvement was sustained for the next 8 months (median of 89%). Conclusion: This study found that CQI approach can be used to improve the compliance of the physicians for appropriately and timely documenting critical alerts, in this case, by continued education and training process and incorporating changes into the electronic hospital information system.

Pre-operative Occurrence of First Bite Syndrome in Two Cases of Parotid Gland Tumour.

Introduction: First bite syndrome (FBS) is a gustatory-evoked painful condition that is characterised by the onset of severe electric shock-like pain in the periauricular region. In the majority of patients, FBS develops postoperatively. However, in rare instances, it may present in a pre-operative setting. Case Description: Two cases of FBS developing preoperatively secondary to parotid gland tumour are presented. The patients, 54 and 30 years old, presented with complaints of electric shock-like pain localised over the periauricular region. In each case, the pain was triggered following the first bite of the meal. In both cases, the pain lasted for few seconds and with subsequent bites subsided only to return at the beginning of the next meal. Practical Implications: Pre-operative occurrence of FBS in the absence of a history of trauma or surgery should necessitate a thorough investigation and follow-up for an underlying salivary gland tumour.

Effectiveness of Nerve Blocks for the Management of Head and Neck Cancer Associated Neuropathic Pain Disorders; a Retrospective Study.

Introduction: A portion of patients with head and neck cancer (HNC)- associated pain may not experience relief in symptoms with non-invasive modalities. A nerve block is a procedure in which a local anaesthetic agent is injected along the nerve track to preferentially block sensory transmission. The literature on the effectiveness of nerve blocks in the management of HNC-related pain is limited. The purpose of this study was to determine the effectiveness of nerve blocks in the management of breakthrough HNC-associated trigeminal or cervical neuropathic pain disorders. Materials and Methods: A retrospective chart review of patients who underwent a nerve block or infiltration procedure in the regions of head and neck for the management of breakthrough HNC-associated trigeminal or cervical neuropathic pain disorders in the Orofacial Pain Medicine Clinic, Shaukat Khanum Memorial Cancer Hospital and Research Centre, between November 2018 and November 2019 was completed. Information regarding demographics, diagnosis and pain characteristics was extracted and reviewed. The Fisher's exact test and Mann-Whitney U-test were used for analysis between independent and dependent variables. Results: A total of 27 participants were included in the investigation, of which 66.7% were male. The average pre-procedure pain score was 6.85±2.54. Following intervention, 81.5% of the participants experienced >75% relief in pain for longer than 48 hours. The mean immediate post-procedure pain score was 0.26±1.02 and the average duration of relief was 6.10±6.50 weeks. The significant effect of nerve blocks was found to be statistically associated with the concurrent use of amitriptyline (P = 0.017). Conclusion: Nerve blocks, as an adjunctive therapy to pharmacologic treatment, can provide significant relief to patients with breakthrough HNC-associated trigeminal and cervical neuropathic pain disorders. However, the duration of relief experienced by the participants is inconsistent. The beneficial effect of nerve blocks appears to be more common in patients that were concurrently using amitriptyline.

First-aid knowledge about tooth avulsion among dentists, doctors and lay people.

In avulsion, teeth are bodily displaced out of the bony socket. Boys, aged 7-9 years, are most prone to avulsion of maxillary central incisors. Tooth avulsion should ideally be treated with immediate replantation. Because of the urgency in treatment, personnel dealing with this injury should have knowledge about the first-aid treatment. This study was conducted to assess the first-aid knowledge about tooth avulsion among dentists, doctors, students, school teachers and the general public in Lahore, Pakistan. Data were collected using a form with one open-ended question about the first-aid treatment of traumatic avulsion. Immediate replantation of the avulsed tooth was suggested by 10.1% of 377 respondents. Among dentists, 45.8% suggested immediate replantation, with the rest suggesting transport of the tooth to a dentist for replantation. Among all other groups (non-dentists) immediate replantation was suggested by 4.6% and transport to a dentist by 3.3%. Non-dentists in Pakistan, including doctors, have insufficient knowledge about the immediate treatment of tooth avulsion. Dentists, in comparison, have significantly more knowledge, but may need training in selection of the appropriate treatment option and handling and care of the avulsed tooth.
