Clinical Features and Prognosis of Uveitis in a Turkish Patient Population with Ankylosing Spondylitis: Incidence and Management of Ocular Complications

Purpose: To investigate clinical features, visual prognosis, and ocular complications in patients with ankylosing spondylitis (AS)-associated anterior uveitis (AU).

Methods: Data of 211 eyes of 145 patients with AU associated with AS were reviewed retrospectively.

Results: Mean follow-up time was 6.31 ± 6.33 years. Men were younger than women at AS diagnosis (p = 0.035). The mean number of uveitis flares was highest during the first quarter of the year and lowest during the third quarter (p = 0.017). Immunosuppressive agent use was higher in women than men (p = 0.052). Ocular complications developed in 120 eyes (56.9%), and the complication rate was 0.146/eye year. Males developed cystoid macular edema more frequently than females (p = 0.05). Glaucoma was observed more often in early-onset disease (age at AS onset <45 years) than late-onset disease (p = 0.028).

Conclusions: Visual prognosis of AU in patients with AS was good, although more than half of the eyes developed ocular complications (56.9%).     

Life-threatening heat-related illness with severe hyponatremia in an aluminum smelter worker

Heat stress is a recognized occupational hazard in aluminum smelter pot rooms. This is the report of an unusual and complex case of heat-related illness in an aluminum smelter worker. The 34-year-old male US worker developed life-threatening heat-related illness in August 2018, on his first day back at work after a 7-day absence. The worker initially presented with bilateral hand then all-extremity cramping followed some hours later by a generalized seizure and acute mental status changes, including combativeness. Emergency room evaluation identified a serum sodium level of 114 mmol/L. Acute liver and kidney injury ensued along with profound rhabdomyolysis, with peak total creatinine phosphokinase level reaching over 125 000 units/L at 3 days post incident. Initial ventilatory support, careful fluid resuscitation, and electrolyte management were provided. Metabolic encephalopathy resolved. Complications included sepsis. After 5 days in the intensive care unit and eight additional days of inpatient management, observation, and the initiation of rehabilitation, the worker was discharged. Residual effects include polyneuropathy of upper and lower extremities and the postdischarge magnetic resonance imaging finding of a cerebellar lesion. Prevailing considerations in the differential diagnosis included exertional heat stroke and/or exertion-associated hyponatremia with encephalopathy.     

Oligometastatic prostate cancer: Reality or figment of imagination?

The term “oligometastatic prostate cancer” refers to a heterogeneous group of disease states currently defined solely on the basis of clinical features. Oligorecurrent disease, de novo oligometastases, and oligoprogressive disease likely have unique biologic underpinnings and natural histories. Evidence suggesting the existence of a subset of patients who harbor prostate cancer with limited metastatic potential currently includes disparate and overwhelmingly retrospective reports. Nevertheless, emerging prospective data have corroborated the “better-than-expected,” retrospectively observed outcomes, particularly in the setting of oligorecurrent prostate cancer. Improved functional imaging with prostate-specific membrane antigen-targeted strategies may enhance the identification of patients with oligometastatic prostate cancer in the short term. In the long term, refinement of the oligometastatic case definition likely will require biologic risk-stratification schemes. To determine optimal treatment strategies and identify patients most likely to benefit from metastasis-directed therapy, future efforts should focus on conducting high-quality, prospective trials with much-needed molecular correlative studies.
