We have experienced a surgeon who had a previous left putaminal hemorrhage and presented with higher brain dysfunctions due to a new right frontal lobe infarction. The patient was a right-handed man in his 50s with inattention, constructive disorder, left hemispatial neglect, and executive dysfunction. The lesions were localized not only in the right inferior and middle frontal gyri but also in deep white matter including the right frontal aslant tract and superior longitudinal fasciculus. The patient gradually resumed work early on with multidisciplinary support and returned to work within 3 months after the onset of the disease. In this case, direct attention training, metacognitive strategy training including time pressure management, and visual search training from the acute stage were successful. Even after the completion of cognitive rehabilitation, an improvement in attention and processing speed was confirmed, suggesting that highly personalized cognitive rehabilitation tailored to higher brain dysfunctions have a lasting effect. However, the improvement of higher brain functions and the resumption of work increased self-awareness and anxiety, leading to a decrease in self-efficacy. Cognitive rehabilitation including metacognitive strategy training, together with psychological support, is important for step-by-step return to work.

Rehabilitation for ocular motility disorder and diplopia after acute cerebral infarction has not been established. In the present case, we describe the course of oculomotor rehabilitation in a patient with left-sided gaze palsy and diplopia due to a stroke in the paramedian part of the left pontine tegmentum. The patient was a right-handed man in his 40s. Cerebral infarction occurred after coil embolization with stenting for an unruptured dissecting aneurysm. He presented with eye movement difficulty resulting from conjugate deviation of the eyes to the right at onset. No other motor-sensory abnormalities were present. Processing speed of Wechsler Adult Intelligence Scale-Fourth Edition was decreased. We performed oculomotor rehabilitation from the acute phase, including fixation, smooth pursuit, saccadic and convergent movements. Visual attention tasks such as visual search and cancellation tasks were applied from 10 days after onset. The oculomotor disorders gradually improved and disappeared by 65 days after onset. The responsible lesion was localized in left paramedian pontine reticular formation and abducens nucleus. Medial longitudinal fasciculus was not involved, which was consistent with the clinical oculomotor findings. The neuropsychological assessments showed that processing speed was improved. Based on the neuropsychological assessments and actual vehicle evaluation, our multidisciplinary team determined that the patient should not refrain from automobile driving. The patient returned to work and resumed driving 86 days after onset. The results suggest that visual attention tasks together with basic oculomotor trainings for ocular motility disorder and diplopia are useful for early return to automobile driving and society.

Background: This study aimed to investigate the relationship between pharyngeal morphology and the success or failure of blind nasotracheal intubation using standard lateral cephalometric radiography and to analyze the measurement items affecting the difficulty of blind nasotracheal intubation. Methods: Assuming a line perpendicular to the Frankfort horizontal (FH) plane, the reference point (O) was selected 1 cm above the posterior-most end of the hard palate. A line passing through the reference point and parallel to the FH plane is defined as the X-axis, and a line passing through the reference point and perpendicular to the X-axis is defined as the Y-axis. The shortest length between the tip of the uvula and posterior pharyngeal wall (AW), shortest length between the base of the tongue and posterior pharyngeal wall (BW), and width of the glottis (CW) were measured. The midpoints of the lines representing each width are defined as points A, B, and C, and the X and Y coordinates of each point are obtained (AX, BX, CX, AY, BY, and CY). For each measurement, a t-test was performed to compare the tracheal intubation success and failure groups. A binomial logistic regression analysis was performed using clinically relevant items. Results: The items significantly affecting the success rate of blind nasotracheal intubation included the difference in X coordinates at points A and C (Odds ratio, 0.714; P-value, 0.024) and the ∠ABC (Odds ratio, 1.178;P-value, 0.016). Conclusion Using binomial logistic regression analysis, we observed statistically significant differences in AX-CX and ∠ABC between the success group and the failure group.

A 15-year-old boy with coronary sinus type atrial septal defect (CS-ASD) was surgically treated with 3-port totally endoscopic technique. The patient was set in a left semi-lateral position. A 3 cm skin incision retracted by a small wound protector, a trocar for the endoscope, and a trocar for left-handed instruments were placed in the right antero-lateral chest. Cardio-pulmonary bypass was established via groin cannulation. After cardioplegic arrest, the CS-ASD was favorably exposed through the left atriotomy, and closed using a bovine pericardial patch. The total operation time was 112 min. The post-operative course was uneventful. Instead of the traditional median sternotomy and right atriotomy, small right thoracotomy and left atriotomy may be a promising alternative for closure of CS-ASD.

A 68-year-old man was referred to our hospital for mitral valve stenosis, tricuspid valve insufficiency and atrial fibrillation. We performed mitral valve replacement, tricuspid valve plasty, and the MAZE operation through a right small thoracotomy under endoscopic assistance. He was discharged uneventfully 7 days after the operation. However, about 2 months later, he developed pericardial effusion, right pleural effusion, and leg edema implying as having right heart failure. Although he was treated with diuretics and steroids, improvement was temporary and he was hospitalized repeatedly. Cardiac catheterization demonstrated dip and plateau pattern of the right ventricular pressure curve. We diagnosed that he has constrictive pericarditis, although the finding of the chest CT was non-specific without remarkable thickening or calcification of the pericardium. We performed pericardiectomy through median sternotomy without pump assist. Leather-like thickening of the pericardium was recognized in the right, anterior, and inferior portion. Resection of the thickened pericardium led to instantaneous improvement of right ventricular motion and drop of central venous pressure. The patient is in NYHA Class I, one year after pericardiectomy. Constrictive pericarditis could occur even after minimally invasive surgery, and that possibility should be kept in mind if intractable right heart failure persists.

1) We compiled lists of accredited training hospitals for postgraduate education from the matching program list and of hospitals that employ board-certified specialists in emergency medicine.We then evaluated the number of training hospitals that employ board-certified specialists.
2) There are 1072 accredited hospitals for postgraduate education. However, only 546 (50.8%) of these hospitals employ board-certified specialists in emergency medicine.
3) Accredited training hospitals with emergency-medicine specialists are prevalent in Okinawa, Tokushima, and Kagawa prefectures.However, the prevalence of these hospitals is surprisingly low in metropolitan areas.
