Cultivating cultural awareness among medical educators by integrating cultural anthropology in faculty development: an action research study.

BACKGROUND: In faculty development, understanding each participant's cultural context is important. However, there is scarce evidence on how to improve cultural understanding in faculty development. Cultural anthropology is a discipline that focuses on developing cultural self-awareness by understanding different cultures. Professionals from this field can be crucial to the goal of cultivating cultural awareness among medical educators. The aims of this study are to 1) develop and modify cultural anthropology sessions in faculty development and 2) evaluate the effectiveness of these sessions, including their long-term impacts. METHODS: The cultural anthropology sessions were organized as part of a longitudinal faculty development program-Foundation Course for Medical Education-at Kyoto University in Japan. The study included 47 medical educators participating in faculty development and three lecturers: two cultural anthropologists and a medical educator. We developed the cultural anthropology sessions and implemented them in the longitudinal faculty development program. In these sessions, cultural anthropologists used inquiry-guided reflection. An action research methodology was employed and repeated in four cycles from 2015 to 2018. Qualitative and quantitative data were collected during the action research cycles. The qualitative data were thematically analyzed. RESULTS: The cultural anthropologists' inquiries fostered learning during the sessions, and three themes-cultural relativism, attention to context, and reframing-were synthesized. As a long-term impact of the sessions, the learners reported becoming more aware of the cultural contexts in their daily educational and clinical activities. CONCLUSIONS: The cultural anthropology sessions in the faculty development program were shown to have enhanced the participants' awareness of cultural contexts. The concept and format of these sessions may be used more widely in faculty development programs.

Supraorbital keyhole approach for paraclinoid aneurysms clipping: A case series with literature review.

Background: Paraclinoid aneurysms (PcAs) are challenging aneurysms due to the complexity of their relation to the surrounding bony and neurovascular structures. Although over the past decade, their management strategy has shifted from transcranial to endovascular approaches; here, we try to revolve around a subcategory to which minimal invasive supraorbital keyhole (SOK) surgery is feasible depending on specific radiological criteria with a literature review. Methods: A group of unruptured PcAs was managed surgically, with a subset that was clipped through the SOK approach. They were selected by preoperative simulation images using 3D computed tomography (CT) angiography (CTA). We also conducted an extensive literature review based on a database available on PubMed and Google Scholar, the yielded cases from the literature review plus our cases were analyzed according to six parameters including their size, location, dome direction, need for clinoidectomy and proximal cervical control, and surgical outcome. Results: From February 2009 to August 2022, 49 cases of unruptured PcAs were managed by clipping, and of these, four cases were clipped by the SOK approach, in addition, four cases were yielded through the literature review. The sizes of the PcAs ranged from 3 to 8 mm. Their location fluctuated from anterior to the superomedial wall and their domes pointed superiorly except for one which points posteriorly. Six of eight cases required anterior clinoidectomy, the outcome was uneventful. Conclusion: A subset of unruptured PcAs are amenable to SOK with criteria such as unruptured small aneurysm (<10 mm) and projected superiorly. These characteristics can be determined preoperatively using CTA.

Glioependymal cyst in the medulla oblongata - A case report.

Background: Glioependymal cysts (GECs) are rare benign lesions that can be found anywhere along the neuroaxis, with most of the reports denoting supratentorial location. Here, we introduce a rare case of successfully treated glioependymal cysts lying in an uncommon location, namely medulla oblongata. Case Description: A 69-year-old lady presented with progressive unsteadiness and swallowing disturbances, and brain magnetic resonance imaging showed a dorsally located lesion within the medulla oblongata; based on the presentation and radiological features, surgical intervention was deemed mandatory. The suboccipital midline approach was used to perform marsupialization of the cyst with shunting through a syringosubarachnoid shunt to prevent future recurrence, and the patient outcome was improved. Conclusion: Medulla Oblongata's location for glioependymal cysts proposed unique diagnostic and operative challenges that may require highlighting for practicing neurosurgeons.

Low Alberta stroke program early computed tomography score within 3 hours of onset predicts subsequent symptomatic intracranial hemorrhage in patients treated with 0.6 mg/kg Alteplase.

BACKGROUND: The significance of early ischemic changes (EICs) on computed tomography (CT) in selecting candidates for thrombolysis remains controversial. The Alberta Stroke Program Early CT Score (ASPECTS) provides a semiquantitative scale that scores EICs within the middle cerebral artery territory using a 10-point grading system. We examined whether ASPECTS can predict the response to intravenous thrombolysis within 3 hours of stroke onset and incidence of secondary hemorrhage. METHODS: Data from the Japan Alteplase Clinical Trial (J-ACT), in which 103 patients were included, were evaluated to assess the efficacy and safety of 0.6 mg/kg alteplase within 3 hours. All CT hardcopies were reevaluated retrospectively using the ASPECTS system. Multivariate logistic regression analysis was undertaken to determine whether an effect of ASPECTS existed on a defined favorable outcome as 0 or 1 on the modified Rankin Scale at 3 months, and symptomatic intracranial hemorrhage (sICH) within 36 hours. RESULTS: The median ASPECTS value was 10 (range 3 to 10), and 56.3% revealed no evidence of EICs. ASPECTS had no effect on the patients' outcome, although a higher age and National Institutes of Health Stroke Scale score were negatively associated with a favorable outcome. On the other hand, lower ASPECTS was significantly associated with sICH (odds ratio [OR] 2.224; 95% confidence interval [CI] 1.227-4.032; P = .0084) and systolic blood pressure (OR 1.090; 95% CI 1.007-1.180; P = .0323) and the pre-ictal use of antiplatelet medications (OR 15.551; 95% CI 1.144-211.374; P = .0393). CONCLUSIONS: In J-ACT, patients with low ASPECTS values have an increased risk of thrombolysis-related sICH.

Social Networking Services as a Tool for Support of Mothers: A Literature Review.

Background: Difficulties experienced by mothers in raising their children can be resolved using social networking services (SNSs). Being aware of issues associated with SNSs in such situations may be useful for supporting mothers. We herein review the issues associated with using SNSs to support mothers. Methods: This review was conducted using an electronic search engine to search for articles that described issues associated with using SNSs to support mothers, and which were published up to August 2022. Results: After screening, a total of 19 articles were included. We thematically categorized the contents into three major issues associated with using SNSs for support of mothers: (1) issues on the management side, (2) issues on the user side, and (3) social and environmental issues. The mainly discussed issues were the safety of using SNSs and/or securing and training human resources on the management side, busyness of mothers on the user side, as well as sociocultural and communication environment-related limitations as social and environmental issues. Conclusions: The issues we detected would aid in developing the use of SNSs as a tool to support mothers. Further research on these issues is needed.

[Postoperative patterns of improvement of symptoms and degrees of satisfaction in families of patients after operations for definite idiopathic normal pressure hydrocephalus: a long-term follow-up study].

PURPOSE: To clarify the patterns of improvement of pre- and post-operative symptoms and family satisfaction in patients with definite idiopathic normal pressure hydrocephalus (iNPN) who responded well to shunt intervention. SUBJECTS AND METHODS: The subjects included 40 patients definitively diagnosed with iNPH and who were followed up for one year or longer (age, 61-85; male-to-female ratio, 18: 22). The study focused on (1) preoperative clinical symptoms, (2) improvements in symptoms at 1, 3, 5, and 12 months after surgery, and the satisfaction of the families based on medical results of the Zarit caregiver burden interview, and infomation through questionnaires to medical personnel. RESULTS: (1) The major symptoms were gait disturbance (G, n=38), dementia (D, n=10), and urinary incontinence (U, n=23). G and D appeared as initial symptoms in 30 and 10 cases, respectively. (2) The rates of postoperative improvement at 1, 3, 5, and 12 months were 94.7%, 94.7%, 97.4%, and 94.7% for G, 43.8%, 62.5%, 71.9%, and 84.4% for D, and 78.3%, 86.96%, 86.96%, and 91.3% for U, respectively. G and U cases improved during the postoperative early stage, and D improved gradually from after the third postoperative month. The family satisfaction before surgery and at 1, 3, 5, and 12 months after surgery was 72.5 +/- 12.8, 68.1 +/- 15.4, 55.7 +/- 9.6, 52.9 +/- 11.4, and 47.3 +/- 7.9 points, respectively. The rate of improvement in satisfaction was higher for D. The satisfaction of the medical personnel was 88 percent (+) at 1 month and tended to remain high for 12 months. CONCLUSION: (1) Preoperative gait disturbance is a major initial symptom in definitively diagnosed iNPN. (2) Postoperative improvement of G and U is obtained at an early stage. In contrast, D tends to improve gradually from after the third postoperative month. The family satisfaction increases as the symptom of D improve. The satisfaction of the medical personnel tends to remain high after the first postoperative month. This study investigated the results of quantitative analyses of the patients symptoms.

[Reinvestigation of CSF outflow resistance value in idiopathic normal pressure hydrocephalus--comparing epidural pressure monitoring with lumbar subarachnoid cerebrospinal fluid pressure monitoring].

PURPOSE: To compare the cerebrospinal fluid (CSF) outflow resistance values (Ro) with epidural pressure (EDP) monitoring and lumbar subarachnoid CSF pressure (L-CSFP) monitoring. SUBJECTS AND METHODS: The subjects were 14 patients with possible iNPH (age: 59-74 years old, ratio of male and female 8:6). All the patients were subjected to an infusion test by a single bolus injection method (1 ml/sec., deltaV: 5 ml, t2: 2 min) as prescribed in the Standard of SINPHONI. EDP was monitored by continuous monitoring and the L-CSFP values By intermittent simple glass tube method (SINPHONI) were measured simultaneously. The Ro (RoEDP, RoL-CSFP) calculated from both methods, (1) the correlation of Ro and (2) the Ro threshold in a shunt effective group (E: nine cases) and a non effective group (NE, five cases) were compared. RESULTS: (1) Although a favorable correlation was found between both Ro measurements (r=0.784), the RoEDP was always higher than the RoL-CSFP. (2) The mean Ro values in the E and NE groups were 36.8 +/- 15.7 mmHg/ml/min, and 10 +/- 2.05 mmHg/ml/min for Ro-EDP, 22.1 +/- 13.95 mmg/ml/min and 6.4 +/- 1.7 mmHg/ml/min for RoL-CSFP, respectively. The approximate thresholds in the E and NE groups were 15 mmHg/ml/min for RoEDP and 10 mmHg/ml/min for RoL-CSFP. CONCLUSION: (1) Although the RoEDP is always higher than the RoL-CSFP, a favorable correlation is found between the RoEDP and RoL-CSFP, (2) The Ro thresholds of the E and NE groups in the infusion test are about 15 mmHg/ml/min for RoEDP and 10 mmHg/ml/min for RoL-CSFP. (3) After this, Ro calculation ought to execute by standard of SINPHONI and the Ro threshold of the E and NE groups is about 10 mmHg/ml/min.

[Significance of shunt efficacy decision of SPECT on idiopathic normal pressure hydrocephalus].

PURPOSE: The purpose of this study was to investigate the significance of the shunt-effect evaluation of SPECT in idiopathic normal pressure hydrocephalus (iNPH). SUBJECTS AND METHODS: The subjects were 15 patients with possible iNPH, aged 62-83 (mean 75.3, the ratio of males to females to 6:9), who were treated at our department during the period from June to September, 2004. All patients received the lumbar tap test (LTT) at the outpatient section before surgery. An L-P shunt was conducted on patients whose the LTT positive or negative with cerebrospinal fluid outflow resistance value (Ro) was 10 mmHg/ml/min. or higher patients. As for SPECT, a 3D-SSP Z-score, as well as an mCBF, was conducted before and after the LTT and within one month after surgery. Comparisons were made for (1) the shunt effect, (2) mCBF before and after the LTT and after surgery, (3) mean cerebral blood flow increase rate (mIR) after the LTT, and (4) 3D-SSP before and after surgery. RESULTS: (1) The shunt was effective for all the patients. (2) The mCBF levels was 30.8 +/- 4.02 ml/100 g/min. before the LTT, 37.1 +/- 100 g/min. after the LTT, and 38.6 +/- 3.4 ml/100 g/min. after surgery. A significant increase in mCBF was observed both after the LTT and after surgery (p < 0.05). (3) The mean mIR after the LTT was 21.2 +/- 8.01%, with all the patients showing 10% or higher. (4) The ischemic patterns in the SD-SSP Z-score before surgery were the frontal type (F: 10 cases, 66.7%), the occipitotemporal type (OT: 3 cases, 20%), and the mixed type (M: 2 cases, 13.3%), but not the parietal localized type. The post-operative course showed no-change in 4 cases, disappearance-reduction in 9 cases, and shift to OT in 2 cases. CONCLUSION: The evaluation factors in the measurement of the cerebral blood flow for evaluation of the shunt effect were the following two items. (1) The mIR of mCBF after the LIT was 10% or higher. (2) As for the preoperative cerebral ischemic patterns, there were many F cases and no parietial localized types found.

Choroid plexus carcinoma presented with spinal dysfunction caused by a drop metastasis: a case report.

A 2-year-old girl demonstrating gait disturbance and dysuria was evaluated and showed two large remote tumors at the left lateral ventricle and lower spinal canal. Pathological analysis demonstrated both of the tumors to be choroid plexus carcinoma (CPC) with high MIB-1 labeling index. The enhanced mitotic propensity would have contributed to an early stage of drop metastasis from the primary site to the sacral sac and following accelerated formation of a longitudinal tumor, which had grown in the subarachnoid space conforming to the spinal canal and finally caused the presenting symptoms of spinal dysfunction. This report shows that CPC can develop exophytically in the subarachnoid space as well as in the ventricle simultaneously before appearance of clinical symptoms and confirms the importance of extensive neuroimaging in its evaluation.
