A case of multiple cerebral hemorrhages followed by shower emboli.

An 87-year-old woman was admitted to our hospital (day 0) because of acute disorientation caused by multiple acute intracerebral hemorrhages. T2*-weighted magnetic resonance imaging (MRI) at admission revealed multiple subcortical old microbleeds indicative of cerebral amyloid angiopathy. Microbleeds in the right cerebellar hemisphere and acute spotty ischemia in the left cerebellum were also identified. The patient had been afebrile, and blood examinations on day 7 were within normal limits of inflammatory findings without antibiotics. On day 11, she developed a high fever and blood culture was performed. Her fever resolved within 2 days of antibiotic administration, although subsequent findings revealed her blood culture was positive for Staphylococcus aureus. Echocardiogram revealed bacterial vegetation in the mitral valve and moderate mitral regurgitation, with a diagnosis of infectious endocarditis (IE). Follow-up MRI demonstrated multiple spotty acute infarctions and an increased number of microbleeds. The patient may have been infected via peripheral infusions administered during the first few days after admission. However, considering the coexistence of acute hemorrhagic and ischemic lesions on MRI, as well as the acute lesions in the cerebellum, it is possible that IE was already latent on admission, and that the multiple brain hemorrhages might have been caused by IE rather than by cerebral amyloid angiopathy.

Watershed cerebral infarction in a patient with a persistent primitive trigeminal artery and contralateral internal carotid artery stenosis: A case report.

Patients with a persistent primitive trigeminal artery frequently have a poorly developed vertebrobasilar arterial system. However, they are not at higher risk of stroke and most are asymptomatic. Left cerebral watershed infarction was identified in a 75-year-old man who presented with aphasia and disorientation on magnetic resonance image (MRI). Additional imaging studies also demonstrated a right persistent primitive trigeminal artery, aplastic basilar artery, and 47% left internal carotid artery stenosis. Antiplatelet medication was administered and he was discharged 2 weeks after admission on aspirin. At the 4-month follow-up, cerebral blood flow in the left watershed territory was still decreased; however, no recurrent stroke had occurred. Although the indication for surgical or endovascular intervention for internal carotid artery stenosis is primarily determined by the degree of stenosis, cerebral blood flow evaluation is recommended in patients with internal carotid artery stenosis and a persistent primitive trigeminal artery.

The cause of anorexia and proportion of its recovery in older adults without underlying disease: Results of a retrospective study.

AIM: It is difficult to determine whether or not end-of-life care is necessary for frail older adults complaining of anorexia without underlying disease, such as cancer or organ failure. The main reason for this is the lack of the specification of the anorexia cause and no understanding of the cause-providing factor and the prognostic factor. This study aimed to clarify the cause of anorexia, and the determinant of the cause and recovery from anorexia. METHODS: Retrospective chart reviews were conducted on patients with anorexia without an underlying disease who were aged ≥65 years and visited the emergency department of a single tertiary care center between 2016 and 2017. Patient characteristics at hospital visit, the cause of anorexia, and diagnostic modalities were summarized. The diagnosis-providing rate, recovery rate, and the association between them were analyzed. RESULTS: Eighty-three patients (mean age 82.3 years; 50.6% male) were investigated. In 67 patients (81%), the causes of anorexia were identified, including 18 patients (22%) with infection, 13 (16%) with benign gastrointestinal diseases, and 7 (8%) with cardiovascular diseases. In 16 patients (19%), the causes of anorexia were not identified despite examinations. The modality that most contributed to diagnosis was plain computed tomography followed by blood tests. The value regarding information in history-taking and physical examinations was limited. Sixty-five patients (78%) recovered. Only 73% of patients with a definite cause recovered; all patients with an unknown cause recovered. CONCLUSIONS: Older adults with anorexia are not always at the end of life, and efforts to identify the cause are crucial. Moreover, it is vital to realize the limitations associated with the treatment of infections and cardiovascular diseases.
