In the Thrombolysis in Myocardial Infarction, Phase II pilot and clinical trial, 908 patients [326 (35.9%) in the pilot study and 582 (64.0%) in the randomized study] were treated with 150 mg recombinant tissue-type plasminogen (rt-PA) activator in combination with heparin and aspirin, and 3,016 patients [64 (2.1%) in the pilot study and 2,952 (97.9%) in the randomized study] were treated with 100 mg rt-PA in combination with heparin and aspirin. Adverse neurological events occurred in 23 patients treated with 150 mg rt-PA (2.5%) [nine cerebral infarctions (1.0%), 12 intracerebral hemorrhages (1.3%), and two subdural hematomas (0.2%)] and in 33 patients treated with 100 mg rt-PA (1.1%) [20 cerebral infarctions (0.7%), 11 intracerebral hemorrhages (0.4%), and two subdural hematomas (0.1%)]. The difference in adverse neurological events observed comparing the two rt-PA regimens was primarily due to a higher frequency of intracerebral bleeding among patients treated with 150 mg rt-PA (1.3% versus 0.4%, p less than 0.01). Patients with recent (within 6 months) histories of stroke were not eligible for the study, and patients with any history of cerebrovascular disease were declared ineligible early in the study. The small number of patients (89, or 2.3%) with any history of neurological disease, intermittent cerebral ischemic attacks, or stroke who were enrolled before the stricter eligibility criteria were imposed or on the basis of incomplete baseline information experienced an increased frequency of intracerebral hemorrhage compared with patients without such histories (3.4% versus 0.5%). Mortality at 6 weeks after presentation among 23 patients who had intracerebral hemorrhage was 47.8%. Intracerebral hemorrhage is a severe but infrequent complication of rt-PA therapy for acute myocardial infarction. The combined frequency of intracerebral hemorrhage, subdural hematoma, and cerebral infarction after treatment with 100 mg rt-PA is comparable to that observed in other trials with thrombolytic agents in acute myocardial infarction.

Parenchymatous intracerebral hemorrhage (ICH) is a serious, infrequent complication of thrombolytic therapy for acute myocardial infarction. We studied the clinical and radiologic features, manner of presentation, associated factors, and temporal course in 23 patients with ICH associated with 150 mg or 100 mg recombinant tissue-type plasminogen activator (rt-PA) and heparin therapy for acute myocardial infarction in the Thrombolysis in Myocardial Infarction (TIMI) II Pilot and Randomized Clinical Trial. In TIMI II, 13 of the 23 ICH patients developed or maintained systolic blood pressure > or = 160 mm Hg or diastolic blood pressure > or = 90 mm Hg during the rt-PA infusion and before the onset of neurologic symptoms. Six patients (26%) had life-threatening ventricular arrhythmias, five before onset of neurologic symptoms. A decreased level of consciousness was the earliest neurologic abnormality in 15 (65%) and the most common initial physical finding (in 19, or 82%). Onset was usually gradual (70%), but time to maximal deficit was frequently (61%) within 6 hours of onset. The locations of the primary ICH sites were lobar in 16 (70%), thalamic in four (17%), and brainstem-cerebellum in three (13%), but the putamen was never the primary site. Multiple lobar hemorrhages occurred in six cases (26%). The timing and size of ICH was similar among patients treated with 150 mg rt-PA and 100 mg rt-PA. Brain CT demonstrated an arteriovenous malformation in one case. Four patients had hypofibrinogenemia, which was profound in three patients. Pathologic findings were available for five patients. Of these, three patients had cerebral amyloid angiopathy, and one had hemorrhagic transformation of an ischemic cerebral infarction found at autopsy. We conclude that ICH following rt-PA and heparin therapy for acute myocardial infarction presents as a distinctive clinical syndrome. Intracerebral bleeding after combined thrombolytic and antithrombotic therapy may be associated with cerebral amyloid angiopathy and other vascular lesions. Acute or persistent hypertension before or during rt-PA infusion, life-threatening ventricular arrhythmias, and hypofibrinogenemia, either alone or in combination, may play roles in some cases. Care should be exercised when considering thrombolytic therapy for patients with risk factors for ICH.

Introduction The term kink describes sexual behaviors and identities encompassing bondage, discipline, domination and submission, and sadism and masochism (collectively known as BDSM) and sexual fetishism. Individuals who engage in kink could be at risk for health complications because of their sexual behaviors, and they could be vulnerable to stigma in the health care setting. However, although previous research has addressed experiences in mental health care, very little research has detailed the medical care experiences of kink-oriented patients. Aim To broadly explore the health care experiences of kink-oriented patients using a community-engaged research approach. Methods As part of the Kink Health Project, we gathered qualitative data from 115 kink-oriented San Francisco area residents using focus groups and interviews. Interview questions were generated in collaboration with a community advisory board. Data were analyzed using a thematic analysis approach. Main Outcome Measures Themes relating to kink-oriented patients' experience with health and healthcare. Results Major themes included (i) kink and physical health, (ii) sociocultural aspects of kink orientation, (iii) the role of stigma in shaping health care interactions, (iv) coming out to health care providers, and (v) working toward a vision of kink-aware medical care. The study found that kink-oriented patients have genuine health care needs relating to their kink behaviors and social context. Most patients would prefer to be out to their health care providers so they can receive individualized care. However, fewer than half were out to their current provider, with anticipated stigma being the most common reason for avoiding disclosure. Patients are often concerned that clinicians will confuse their behaviors with intimate partner violence and they emphasized the consensual nature of their kink interactions. Conclusion Like other sexual minorities, kink-oriented patients have a desire to engage with their health care providers in meaningful discussions about their health risks, their identities, and their communities without fear of being judged. Additional research is needed to explore the experiences of kink-oriented patients in other areas of the country and internationally.

Autoimmune encephalitis associated with antibodies (Abs) directed against the synaptic ligand-gated ion channel NMDA receptor (NMDAR) was first described as a paraneoplastic disorder in association with ovarian teratoma. Other forms of neoplasia have subsequently been reported although many patients do not have a tumour. Tumour removal, where applicable, and immunotherapy form the mainstays of treatment. We present a patient who developed NMDAR-Ab encephalitis despite being chronically immunosuppressed following organ transplantation, and who was eventually found to have an occult malignancy in the form of non-Hodgkin's lymphoma.
