The literature on palinopsia (visual perseveration) is reviewed, utilizing case reports of 46 patients who demonstrated this symptom. The most common etiologies for this symptom are space-occupying lesions, cerebral infarct, and seizure activity. The vast majority are due to central nervous system pathology occurring in the posterior (occipital or parieto-occipital) region, often in the right hemisphere. Proposed mechanisms for palinopsia are also discussed.

Complications of endoscopic and classic intranasal sinus surgery have been documented by case reports and large retrospective reviews. The most serious complications have involved violation of the intracranial space or orbit. Hemorrhage has also proven to be a significant cause of morbidity, either of itself, or by limiting visualization and thus contributing to other injuries. Although numerous studies have been performed to determine various anatomic relationships, relatively few have addressed relationships that use practical reference points easily accessible to the endoscopic or intranasal sinus surgeon. In an effort to reduce the risk of complications such as blindness, orbital hematoma, and injury to the lacrimal sac or central nervous system, we have performed 50 cadaver dissections and measured 7 anatomic landmarks that may aid the surgeon in preventing these complications. We have also included a review of the literature concerning the complications of endoscopic and intranasal sinus surgery addressed herein.

Propylene glycol (PG) is a commonly used solvent for oral, intravenous, and topical pharmaceutical agents. Although PG is generally considered safe, when used in high doses or for prolonged periods, PG toxicity can occur. Reported adverse effects from PG include central nervous system (CNS) toxicity, hyperosmolarity, hemolysis, cardiac arrhythmia, seizures, agitation, and lactic acidosis. Patients at risk for toxicity include infants, those with renal or hepatic insuficiency, epilepsy, and burn patients receiving extensive dermal applications of PG containing products. Laboratory monitoring of PG levels, osmolarity, lactate, pyruvate, bicarbonate, creatinine, and anion gap can assist practitioners in making the diagnosis of PG toxicity. Numerous studies and case reports have been published on PG toxicity in adults. However, very few have been reported in pediatric patient populations. A review of the literature is presented.

Central nervous system involvement is a rare complication of multiple myeloma with extremely poor prognosis as it usually fails to respond to therapy. We present 13 cases diagnosed at two centers in Budapest and review the current literature. The majority of our cases presented with high-risk features initially; two had plasma cell leukemia. Repeated genetic tests showed clonal evolution in 3 cases. Treatments varied according to the era, and efficacy was poor as generally reported in the literature. Only one patient is currently alive, with 3-month follow-up, and the patient responded to daratumumab-based treatment. Recent case reports show promising effectivity of pomalidomide and marizomib.
