Rehabilitation of a Patient with COVID-19 Who Underwent Right Transfemoral Amputation Due to Acute Limb Ischemia: A Case Report.

Background: Coronavirus disease 2019 (COVID-19) is associated with an increased risk of thrombotic complications. Nonetheless, there is a paucity of clinical knowledge regarding rehabilitation of patients with COVID-19 after lower-limb amputation. Case: A 74-year-old woman with COVID-19 was admitted to a university hospital. During hospitalization, she underwent right transfemoral amputation due to acute limb ischemia. Three months after admission, the patient was transferred to a convalescent rehabilitation ward in the same hospital. A femoral prosthesis was prescribed 2 weeks after her transfer to the rehabilitation ward. It featured ischial-ramal containment with a soft liner and belt suspension, 668-g multiple linkage-type safety knee joint (Imasen Engineering; M0781 SwanS), and a solid-ankle cushioned-heel foot. The total rehabilitation time during the patient's stay in the acute-care and rehabilitation wards was 65.5 h (0.99 h/day, 66 days) and 275.0 h (3.02 h/day, 91 days), respectively. In the rehabilitation ward, the patient underwent 54.4 h (19.8%) of muscle strength training, 48.1 h (17.5%) of comprehensive assessments, and 47.1 h (17.1%) of gait training. The patient was discharged home 6 months after admission, with a total Functional Independence Measure score of 120. The patient could walk slowly [44.2 s (0.23 m/s) in the 10 m-walk test] with a femoral prosthesis and a quad cane but exhibited limited endurance (75.0 m in the 6-min walk test). Discussion: Following appropriate rehabilitation, a patient was able to walk independently after lower-limb amputation despite the complication of COVID-19, although her walking ability was limited.

Persistent brain damage in reversible cerebral vasoconstriction syndrome on 99mTc-ethyl cysteinate dimer single-photon emission computed tomography: A long-term observational study.

BACKGROUND: Blood-brain barrier (BBB) breakdown is considered a key step in the pathophysiology of reversible cerebral vasoconstriction syndrome (RCVS); however, its temporal course remains unclear. Based on the characteristics and dynamics of 99mTc-ethyl cysteinate dimer (99mTc-ECD) as a tracer, 99mTc-ECD single-photon emission computed tomography (SPECT) can detect not only hypoperfusion but also BBB breakdown and/or brain tissue damage. Therefore, this study aimed to investigate this course using 99mTc-ECD SPECT. METHODS: Between 2011 and 2019, we enrolled seven patients (one male and six female patients) with RCVS without ischemic or hemorrhagic stroke or posterior reversible encephalopathy syndrome. 99mTc-ECD SPECT was performed repeatedly in each patient. SPECT data were statistically analyzed using an easy Z-score imaging system. RESULTS: Thunderclap headache was the initial symptom in all the patients and was most commonly triggered by bathing (three patients). All the patients exhibited vasoconstriction and reduced cerebral uptake of 99mTc-ECD during the acute stage. Follow-up assessment from 3 to 16 months showed that reduced cerebral uptake persisted in all the patients, even after the vasoconstriction had resolved. CONCLUSION: Reduced cerebral uptake of 99mTc-ECD persisted in the late stage of RCVS, even after vasoconstriction and headache subsided. BBB breakdown and/or brain tissue damage may underlie this phenomenon. 99mTc-ECD SPECT is an effective neuroimaging method to detect brain functional abnormalities, reflecting BBB breakdown or tissue damages, throughout the treatment course of RCVS.

Evaluation of a carbapenem antimicrobial stewardship program and clinical outcomes in a Japanese hospital.

INTRODUCTION: Microorganisms can evolve and become resistant to antimicrobials, and this is known as antimicrobial resistance (AMR). Inappropriate use of antibiotics contributes to AMR, and antimicrobial stewardship programs have been developed to mitigate AMR. The Appropriate Use of Carbapenems Program was implemented in March 2019 in a university hospital and its effect was evaluated. METHODS: We conducted a prospective audit and feedback on carbapenems at the time of prescription daily. Additionally, we compared a monthly survey of the total days of therapy (DOTs) per 1000 patient-days for carbapenems, piperacillin/tazobactam, and fluoroquinolones. The susceptibility of Pseudomonas aeruginosa to meropenem, piperacillin/tazobactam, and levofloxacin was tested before (January 2018 to February 2019) and after (March 2019 to December 2020) the intervention. RESULTS: The monthly median DOTs of carbapenem usage decreased after the intervention; carbapenem use immediately declined during the intervention period. The monthly median DOTs of piperacillin/tazobactam and fluoroquinolones also decreased and continued to decline significantly after the intervention. Susceptibility of P. aeruginosa to meropenem, piperacillin/tazobactam, and levofloxacin did not change significantly during the study. CONCLUSION: The implementation of the Appropriate Use of Carbapenems Program was effective in reducing the use of broad-spectrum antibiotics and maintaining the antibiotic susceptibility of P. aeruginosa.

Alternating Amaurosis Fugax in Trousseau Syndrome: A Case Report.

Amaurosis fugax (AmF) is defined as transient monocular visual loss secondary to retinal ischemia. In most patients presenting with AmF, the attack of visual loss occurs in the same eye. A 64-year-old woman experienced transient visual loss in her right eye. Three days after that, an attack happened on the left side. In total, she had 5 episodes of AmF in 2 months. AmF occurred on both sides at different times, and so may be referred to as "Alternating AmF". Diffusion-weighted magnetic resonance imaging showed high-intensity lesions in various parts of brain, and laboratory examination revealed elevated D-dimer and ovarian tumor marker. We suspected Trousseau syndrome and found a giant ovary tumor. After removal of the tumor, no recurrence was observed. When a patient with alternating AmF is encountered, screening for malignancy is essential.

Ten-Year Evaluation of the TOYOTA Prehospital Stroke Scale for Tissue Plasminogen Activator Intravenous Therapy in the Real World.

BACKGROUND: Emergency medical services are an important part of acute stroke management. We devised a prehospital stroke scale, the TOYOTA prehospital stroke scale for tissue plasminogen activator (t-PA) intravenous therapy (TOPSPIN) for triaging patients with ischemic stroke and especial indications for intravenous t-PA therapy in December 2006; this scale comprises 5 items including consciousness, atrial fibrillation, language disorder, disturbance of the upper extremities, and disturbance of the lower extremities. The aim of this study was to analyze the results of 10 years of TOPSPIN implementation and to distinguish ischemic stroke from hemorrhagic stroke in the real world. METHODS: We prospectively enrolled consecutive patients who were transferred to our hospital and evaluated by Toyota city ambulance services using the TOPSPIN from December 2006 to January 2017. We examined definite diagnosis at the time of hospital discharge (ischemic stroke, hemorrhagic stroke, or stroke mimic), positive-predictive value of the stroke, the rate of the recanalization therapy, and clinical differentiation among patients with hemorrhagic stroke, ischemic stroke, and stroke mimics. RESULTS: A total of 1,482 consecutive patients were enrolled; 1,134 (76.5%) were patients with stroke (628 ischemic-type, 34 transient ischemic attack-type, and 472 hemorrhagic-type) and 348 (23.5%) without stroke (80 with seizure, 42 with syncope, 27 with hypoglycemia, and 199 other). Among 628 patients with ischemic stroke, 130 (20.7%) received intravenous recombinant t-PA treatment, endovascular therapy, or both. The presence of atrial fibrillation, older age, lower blood pressure, and lower total TOPSPIN score was more commonly associated with ischemic stroke than with hemorrhagic stroke. In multivariable logistic regression analysis, the presence of atrial fibrillation was independently associated with ischemic stroke (OR 2.33; 95% CI 1.61-3.40). CONCLUSIONS: The TOPSPIN is a simple prehospital stroke scale that includes an assessment of atrial fibrillation. Detection of atrial fibrillation in the prehospital stage may point to a higher probability of ischemic stroke.

[A pedigree of hereditary hyperekplexia].

A 31-year old women presented with excessive startle reflex and frequent falls. Her startle reflex is induced by slight stimuli which are not problematic in most people. Soon after her startle reflex is evoked, generalized muscle stiffness occurs. She becomes rigid and falls down without loss of consciousness. Because she cannot protect herself when she is startled and falls, she has repeatedly bruised her head and face. The pedigree includes her father and two sisters with similar symptoms. Gene analysis revealed GLRA1 mutation, and she was diagnosed with hereditary hyperekplexia (HPX). Symptoms improved with clonazepam 1 mg/day. HPX patients live with severe anxiety about frequent falls and sometimes suffer serious injury, such as cerebral concussion or bone fracture. Although HPX might sometimes be underestimated, accurate diagnosis is very important for effective treatment.
