Treatment-resistant diabetic chorea manifesting with psychiatric symptoms: a case report.

We report a case of a 69-year-old man with treatment-resistant diabetic chorea presenting psychiatric symptoms. The right chorea lasted for 3 months and was refractory to control of diabetes mellitus or administration of haloperidol and benzodiazepines. Only administration of tiapride was efficacious. Magnetic resonance spectrometry and dopamine transporter-single photon emission computed tomography suggested that sustained ischemia at the striatum may lead to impaired expression of dopamine transporters, thereby resulting in deterioration in the indirect pathway. Tiapride inhibited dopamine D2 receptors, thereby restoring the function of the indirect pathway and resulting in improvement of diabetic chorea.

Clinical Characteristics of Driving-related Stroke Occurring as a Recurrent Stroke.

BACKGROUND: Although the number of seemingly healthy subjects who suffer a minor stroke increases, there are no data on how frequently they sustain another stroke while driving. METHODS: A single-center, retrospective study was conducted to clarify the clinical characteristics of driving-related stroke occurring as a recurrent stroke by analyzing data prospectively acquired between January 2009 and June 2019 on 3452 acute stroke patients. RESULTS: One hundred-thirty five patients (85 ischemic stroke [IS] and 50 hemorrhagic stroke [HS]) had suffered a driving-related stroke. Of them, 22 (16%) had suffered a prior stroke (recurrent stroke group), while 113 had never suffered a stroke before (first-time stroke group). While the use of anti-thrombotics was significantly more common in the RS group, other variables including the frequency of road traffic accidents, did not differ significantly. The first stroke-recurrent stroke interval ranged from 0.2 to 18 years. The stroke type at the time of recurrence was IS in the majority of patients with prior IS. When compared to 432 patients with recurrent IS unrelated to driving, patients with recurrent IS related to driving (n = 16) had significantly higher frequency of lacunar strokes (56% vs 27%, P = .02) and lower frequency of cardioembolic strokes (6% vs 29%, P = .04). CONCLUSION: The current finding that 16% of patients who presented with driving-related stroke had previously suffered a stroke indicates that drivers with a prior stroke may be at increased risk for recurrent stroke while driving, and prolonged follow-up be necessary for minor stroke patients who resume driving.

Lacosamide Intoxication-induced Wide QRS Tachycardia Successfully Treated with Veno-arterial Extracorporeal Membrane Oxygenation.

Lacosamide is an antiepileptic drug that acts on voltage-gated sodium channels and was approved as an antiepileptic by the Food and Drug Administration in 2008. Although the efficacy and safety of lacosamide have been established in many previous trials, some case reports have shown that it may lead to cardiovascular side effects, especially in patients with electrical conduction system disorders. We herein report a case of life-threatening cardiac arrhythmia caused by lacosamide intoxication that was successfully treated with veno-arterial extracorporeal membrane oxygenation.

[Real-time 3D reconstruction CT-jejunography guided direct percutaneous endoscopic jejunostomy for levodopa-carbidopa intestinal gel treatment in a patient with prior gastrojejunostomy].

A 68-year-old woman with Parkinson's disease, who had previously undergone Roux-en-Y gastrojejunostomy for early gastric cancer, complained of wearing-off and troublesome dyskinesia that had progressed over 7-years. After the introduction of levodopa-carbidopa intestinal gel therapy (LCIG) by nasojejunal tube, she had a good clinical response. Percutaneous endoscopic gastrostomy with a jejunal extension tube was difficult in this case, due to lack of gastrostomy site and fibrous postoperative adhesion. We introduced LCIG by direct percutaneous endoscopic jejunostomy (D-PEJ) which offers a less invasive procedure to operative tube placement. The factors affecting the success of D-PEJ could interfere with transillumination, abdominal thickness and the location of other organs. We determined the optimum site of catheter insertion with the assistance of real-time 3D reconstruction CT-jejunography. She was discharged home on postoperative day 14 without any procedure-related complications. Real-time 3D reconstructive CT-jejunography guided D-PEJ is a useful method for a patient who benefit from LCIG with prior gastrojejunostomy.

Red face may be a specific sign of SARS-CoV-2 alpha variant.

Japan is currently suffering the fourth wave of the COVID-19 pandemic, with the dominant type being SARS-CoV-2 alpha variant. Patients with COVID-19 variant types show more aggressive symptoms. In the present study, three patients developed a red face during treatment. Two of them suddenly worsened shortly after. We assumed that the red face reflected a cytokine storm and conjectured that it may be a specific sign of variant type COVID-19, because we have never seen it in patients with non-variant type. Moreover, we believe that red face may be predictive of a sudden deterioration.

Hiccups as a specific neurological manifestation in males with COVID-19.

Several clinical manifestations of COVID-19 have been reported in the literature since then. In addition to upper respiratory symptoms, dysgeusia and anosmia are relatively common neurological manifestations with COVID-19. We had five cases of hiccups in succession; therefore, we assume that hiccups might be a specific symptom of COVID-19. We retrospectively analyzed 46 patients with COVID-19 diagnosed from February 2021 to May 2021. Among the 46 patients, 5 developed hiccups (11%). All patients were male. The median age of was 56 years. None of the patients were smokers. Further, all patients exhibited pneumonia without dysgeusia or anosmia. The median onset of hiccups was 5 days after diagnosis, with a median duration of 2 days. All patients recovered from hiccups and COVID-19. Hiccups might be a specific neurological symptom in male patients with COVID-19.

[Wilson's disease presenting as Asperger syndrome].

A 24-year-old man, who had been treated for 3 years as Asperger syndrome in adolescence due to behavioral disturbances, lack of social awareness and inability to socialize, was referred to our hospital shortly after tremors developed. On the basis of clinical features, laboratory findings and the brain MRI, a diagnosis of Wilson's disease (WD) was made. WD was further confirmed by genetic testing (the mutation of ATP7B gene). He was started with trientine hydrochloride 500 mg/day, and after 1 year of follow-up, his psychiatric symptoms have improved. Since psychiatric symptoms may precede the neurological symptoms, the possibility of WD should be always considered in the differential diagnosis of psychiatric disorders in young adults.

Clinical characteristics of stroke occurring in the toilet: Are older adults more vulnerable?

AIM: While autonomic imbalance during defecation/micturition can cause hemodynamic instability, stroke occurring in the toilet has rarely been investigated. The objective of the present study was to clarify the frequency and clinical characteristics of toilet-related stroke. METHODS: Clinical data prospectively acquired between January 2011 and December 2015 on 1939 patients with acute stroke (1224 cerebral infarctions [CI], 505 intracerebral hemorrhages [ICH] and 210 subarachnoid hemorrhages [SAH]) were reviewed to identify patients with a toilet-related stroke. For each stroke type, the ratios of stroke occurring during defecation/micturition to those occurring during other activities were calculated. Subsequently, how patients with toilet-related stroke were brought to medical attention was investigated. Whether older patients (aged >65 years) had an elevated ratio of toilet-related stroke was investigated in each stroke type. RESULTS: A total of 108 patients (41 CI, 37 ICH and 30 subarachnoid hemorrhages) sustained a stroke in the toilet. The ratio of toilet-related stroke was highest in subarachnoid hemorrhages (14.3%), followed by ICH (7.3%). Circadian differences existed among the three stroke types: toilet-related CI were more likely to occur in the night-time than ICH. Patients with toilet-related CI were significantly more likely to sustain cardioembolic stroke. In all three stroke types, <40% of patients could call for help by themselves. Older patients showed a significantly higher proportion of toilet-related stroke in CI, but not in hemorrhagic strokes. CONCLUSIONS: The toilet is a closed space where stroke occurs disproportionately frequently. Effort to reduce the incidence of toilet-related strokes is warranted, as early patient detection is not always feasible. Geriatr Gerontol Int 2018; 18: 250-255.

Stroke while driving: Frequency and association with automobile accidents.

Background Cardiovascular events while driving have occasionally been reported. In contrast, there have been few studies on stroke while driving. Aim The objectives of this study were to (1) report the frequency of stroke while driving and (2) evaluate its association with automobile accidents. Methods Clinical data prospectively acquired between January 2011 and December 2016 on 2145 stroke patients (1301 with ischemic stroke, 585 with intracerebral hemorrhage, and 259 with subarachnoid hemorrhage) were reviewed to identify patients who sustained a stroke while driving. The ratio of driving to performing other activities was evaluated for each stroke type. Furthermore, the drivers' response to stroke was reviewed to understand how automobile accidents occurred. Results Among the 2145 patients, 85 (63 ischemic stroke, 20 intracerebral hemorrhage, and 2 subarachnoid hemorrhage) sustained a stroke while driving. The ratio of driving to performing other activities was significantly higher in ischemic stroke (4.8%) than in intracerebral hemorrhage (3.4%) or subarachnoid hemorrhage (0.8%). A majority of drivers either continued driving or pulled over to the roadside after suffering a stroke. However, 14 (16%) patients were involved in automobile accidents. In most patients, an altered mental status due to severe stroke was the presumed cause of the accident. Conclusion Stroke occurred while driving in 4.0% of all strokes and accidents occurred in 16% of these instances.
