This is especially so in Asians where OSAS is commonly observed in people who are not overly obese. We report a case of a female patient who presented with recalcitrant MD disease and was later found to have concomitant OSA. The relevant literature will be reviewed, and learning points will be discussed from the perspective of the otologist/neurotologist. The clinician must always be mindful of the existence of concomitant “silent” OSAS as this impacts the management of patients with MD.The emerging literature on the novel coronavirus pandemic has reported several cases of varied retinal findings in patients with COVID-19. We report the case of a 59-year-old male who presented with complaint of bilateral blurry vision following hospital discharge after prolonged hospitalization for severe COVID-19 illness. On ocular exam, the patient demonstrated bilateral cotton wool spots localized to the posterior pole of each eye. Multimodal imaging demonstrated findings consistent with retinal nerve fiber layer infarcts in the areas of the cotton wool spots. Exam and imaging of our patient were most consistent with a Purtscher-like retinopathy. We suggest that as ophthalmologists care for increasing numbers of patients recuperating from COVID-19, they monitor for microangiopathic changes similar to those in our patient.The authors present a retrospective, observational case study of seven patients, who presented with retained Intra-Orbital Foreign Bodies (IOrbFBs) following penetrating orbital injury at a tertiary eye hospital over a period of one year. Cases were reviewed for epidemiological features, mechanism of injury, nature of foreign body, clinical features, imaging modality, associated complications, management outcomes, and the final prognosis. The mean age of presentation was 27.43 years. Amongst the seven patients, two were children (aged less then 10 years). The male female ratio was 4 3. Of the seven retained IOrbFBs, two were plastic, two wooden, and three metallic in nature (one gunshot injury, one ball projectile (commonly referred to as BB) injury, and one with knife). Two out of seven had no light perception at presentation. The periocular location of the foreign bodies was inferior in 4 cases and medial in 3 cases. Computed Tomography scan confirmed the diagnosis in five cases and Magnetic Resonance Imaging (MRI) was diagnostic in one. Surgical intervention was done in five cases, and two cases were managed conservatively. The authors conclude that favourable outcome can be achieved even without surgical removal in cases of inert metallic/inorganic IOrbFBs. The properties of plastic FBs can frequently render them invisible on imaging, or they may mimic chronic inflammatory conditions like tuberculosis. Long-standing wooden IOrbFBs evade identification radiologically due to prolonged hydration. The ultimate choice of intervention must be individualised, weighing the risks of retention against the risk of iatrogenic damage.Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) are rare tumors composed of two different histological components, one of which is of a neuroendocrine origin. Given its suggested underdiagnosis and consequent low prevalence, no clear diagnostic and treatment guidelines are available, and treatment usually follows regimens similar to that of the most aggressive component. On the other hand, multiple primary tumors (MPTs) are also rare neoplastic entities that usually confer a challenge regarding treatment options, for a regimen that comprises both the primary and the synchronous/metachronous malignancy should be used. Here, we discuss the challenging diagnostic and therapeutic management of a patient with an ileocecal MiNEN that presented along with a synchronous squamous non-small-cell lung cancer (SQ-NSCLC). The patient presented with intestinal obstruction symptoms for which he underwent an emergency resection of the ileocecal MiNEN. An initial CT scan showed an additional lung mass later identified as an SQ-NSCLC after bronchoscopy biopsy analysis. Given the rapid hepatic metastatic progression, palliative platinum-based chemotherapy was initiated, with an adequate response of the local and metastatic lesions of the MiNEN, but suggested platinum resistance and progression of the pulmonary neoplasm. learn more Second-line treatment with pembrolizumab directed for the SQ-NSCLC was initiated; however, it was stopped after immune-mediated toxicities developed. A third-line chemotherapy scheme with carboplatin/gemcitabine was initiated, but central nervous system (CNS) progression developed, with the patient dying 11 months after initial diagnosis.Immune checkpoint inhibitors, such as nivolumab, a programmed death receptor-1 (PD-1) inhibitor, have dramatically improved the treatment of advanced melanomas. Chemosaturation with percutaneous hepatic perfusion (PHP) delivers chemotherapy in high doses directly to the liver and is a potentially effective treatment modality in metastatic uveal melanoma with liver metastases. Its safety and effectiveness have not been studied in patients also receiving immunotherapy. A 46-year-old male with a history of uveal melanoma of the right eye was found to have liver metastases. He was treated with PHP using high-dose melphalan for 6 months with a partial response followed by progression. Two months after his last PHP treatment, the patient was started on nivolumab. After two doses of nivolumab, the patient developed severe hepatitis that progressed to fulminant hepatic failure and death despite treatment with high-dose corticosteroids and mycophenolate mofetil. Nivolumab and other immune checkpoint inhibitors have been effective in treating advanced melanoma and extending life. However, there are serious immune adverse events that can occur. While hepatitis after taking nivolumab has been documented, fulminant hepatic failure is rare. We believe that prior PHP treatment contributed to the severity of the hepatitis and, ultimately, fulminant hepatic failure. To our knowledge, this is the only case of fulminant hepatic failure secondary to a checkpoint inhibitor with preceding PHP. Specific precautions should be made in patients who have been exposed to PHP in the past, and further studies should be done to assess the safety of using checkpoint inhibitors after PHP.
