BACKGROUND: Experimental data indicate that low-flow reperfusion following prolonged cardiocirculatory arrest may aggravate early cerebral microcirculatory repefusion disorders. We investigated the influence of cerebral repefusion flow change to the ischemic histopathologic damage of brain tissue after incomplete forebrain ischemia in rats. MATERIALS AND METHOD: Anesthetized Sprague-Dawley rats were undergone ligation of both infernal carotid artery by microvascular clamp for 10 minutes. After release of the clamp, reperfusion was started with several different flow levels (0, 10, 20, 30, 50, and 100%) of infernal carotid artery comparing to pre-clamping phase using flowmeter. After 15minutes of reperfusion, rat brains were prepared by perfusion-fixation with 3% formaldehyde. Under light microscopic examination of Hematoxylin-Eosin stained tissue slide, histopathologic damage was examined at cortex, putamen, and hippocampus regions. Categorical hisotopathologic damage scores were derived in each regions by manual counts of ischemic neurons. RESULT: The histopathologic damage scores were 0, 10. 2+/-0.5, 7.6+/-1.5, 5.9+/-1.4, 5.0+/- 2.8, 3.5+/-0.7, and 1.0+/-0.0 in control, 0, 10, 20, 30, 50, and 100% reperfusion groups, respectively(p<0.05). CONCLUSION: Our insults showed significant increment of brain histopathologic damage scores along with decreasing amount of cerebral reperfusion know after incomplete forebrain ischemia. We believe restoration of repefusion flow to pre-ischemic level would be a critical component in attenuation of brain ischemic damage.

Journal of the Korean Radiological Society 2021;82(1):173-181
Purpose:
To evaluate the ability of the Hounsfield unit (HU) measurement of the femoral neck during multidetector computed tomography (MDCT) for assessing osteoporosis compared with dual-energy X-ray absorptiometry (DXA).
Materials and Methods:
Forty-two patients with femoral neck fractures who underwent MDCT and DXA from July to December 2016 were included in this study. HU measurements were made of the cancellous portions of the normal contralateral femoral neck on MDCT. Bone mineral density (BMD) and T-scores were obtained at the femur DXA. Correlations of HU values with BMD and T-scores were analyzed using Spearman’s correlation test.
Results:
The mean BMD and T-score of the femoral neck were 0.650 g/cm2 and -2.4, respectively. The mean HU values for the normal, osteopenia, and osteoporosis groups were 131.9, 98.9, and 41.3, respectively. HU values at the femoral neck were positively correlated with BMD (r2 = 0.670; p < 0.001) and T-scores (r 2 = 0.676; p < 0.001).
Conclusion
The HU values of the femoral neck on MDCT are significantly correlated with BMD and T-scores of femur DXA. The HU values may serve as a diagnostic tool for the screening of regional bone quality when MDCT is performed for other reasons.

Purpose:
The purpose of this study was to compare fatigue, depression, and psychosocial well-being according to level of care dependency in stroke patients.
Methods:
140 stroke patients participated in this descriptive correlation study. Data were collected from July 12, 2019, to March 25, 2020. The data collected using a structured questionnaire on care dependency, fatigue, depression, psychosocial well-being. To analyze the data, mean, standard deviation, x2 test, ANCOVA, and Pearson's correlation coefficients were used.
Results:
Stroke patients with moderate to high level of care dependency showed higher fatigue compared to patients with low care dependency. The patients with high care dependency presented significantly higher depression than the patients with low and the moderate care dependency patients did. Low care dependency group had higher psychosocial well-being scores compared to moderate care dependency group, while moderate care dependency group had higher psychosocial well-being scores compared to high care dependency group.
Conclusion
The results of this study showed that stroke patients with high care dependency presented high fatigue and depression in addition to low well-being. Therefore, it is necessary to develop and apply nursing interventions to reduce fatigue and depression and to promote psychosocial well-being for the patients with high level of care dependency.

6.Cytomegalovirus-associated esophageal ulcer in an immunocompetent infant: When should ganciclovir be administered?.

Cytomegalovirus (CMV)-associated esophageal ulcer is rare in immunocompetent infants. The presence of inclusion bodies and immunohistochemical staining for CMV in biopsy specimens obtained during esophagogastroduodenoscopy (EGD) indicate that such ulcers occur because of CMV infection. A 7-week-old female infant who experienced frequent vomiting and feeding intolerance was diagnosed with a massive CMV-associated ulcer in the distal esophagus. The ulcer improved after conservative treatment using proton-pump inhibitors; however, ganciclovir was not administered. In a follow-up EGD biopsy specimen, no CMV inclusion bodies were present, and immunohistochemical staining results for this virus were negative. The presence of CMV inclusion bodies indicates active viral replication. If persistent inclusion bodies or positive immunohistochemical staining for CMV is observed in follow-up biopsy specimens, ganciclovir may be used to treat CMV-associated esophageal ulcers.

Background: Conventional laryngoscopy with Macintosh blade requires a movement of the head, neck and cervical spine. The Bullard laryngoscope is an anatomically shaped, potentially eliminating the need for cervical spine extension. Bullard and Macintosh laryngoscopes were compared by measuring the degree of cervical spine extension by radiological measurement. Methods: Eighteen patients requiring endotracheal intubation were studied. Anesthesia was induced in neutral head position followed by laryngoscopy. Each patients was intubated two times by Macintosh and Bullard laryngoscope in random order. Radiographic evaluation was performed to determine the degree of cervical spine extension on four occasions; before induction, during facial mask ventilation, and during Bullard and Macintosh laryngoscopy. Results: The extension of cervical spine was significantly less following Bullard laryngoscopy than Macintosh laryngoscopy for best view (p<0.05). Conclusions: The Bullard laryngoscope can be used with less cervical spine extension than Macintosh laryngoscope. It may be useful in patients in whom cervical spine movement is limited or undesirable.

PURPOSE: Pathologic aerophagia (PA) may lead to bowel perforation or volvulus in mentally retarded patients. The authors investigated the effects of clonazepam on the management of PA in children with severe to profound mental retardation (MR). METHODS: This study was undertaken as a retrospective case analysis of 21 PA patients with MR who were followed for over 12 months and diagnosed as having PA. Patients were assigned to two management groups, that is, to a clonazepam randomized open-labeled, treatment group or a reassurance group. The following were recorded and analyzed; age, response, remission rate to clonazepam treatment, and the side effect of clonazepam. It was defined positive response (response+) as being symptom-free for a whole week within 1 month of commencing treatment and remission(+) as being symptom-free for a whole month within 6 months of treatment. RESULTS: The average age of the 21 PA children with MR was 10 years and 13 patients were female. Symptom duration before diagnosis of PA was 7 months. Clinical features of the clonazepam-trial group (n=11) and the reassurance group (n=10) were non-significantly different. Response(+) was achieved by 2 patients (18.2%) in the clonazepam-trial group and by no patient in the reassurance group. Remission(+) was achieved by 6 patients (54.5%) in the clonazepam-trial group and by one patient (10%) in the reassurance group (p=0.040). CONCLUSION: When PA children with MR with severe bowel distention are considered for surgical treatment to prevent acute abdomen, a trial of clonazepam could be recommended.
