Determination of the need for tricuspid valve replacement: value of preoperative right ventricular angiocardiography

Of 530 patients undergoing tricuspid valve surgery from January 1, 1961 through December 31, 1987, those 362 patients having had preoperative right ventricular angiocardiography were studied. Mean age was 58.5 years. There were 71 males and 291 females. Tricuspid valve replacement (TVR) was performed in 126 (34.8%), and 236 underwent tricuspid valve repair (65.2%). The predominant pathology was combined tricuspid insufficiency and stenosis in 18 patients (4.9%), and isolated tricuspid insufficiency in 344 (95.1%). There were no complications related to the right ventriculogram. Preoperative angiographic severity of tricuspid valve incompetence was grade 1 in 23 patients (6.4%), grade 2 in 65 (17.9%), grade 3 in 109 (30.1%), and grade 4 in 165 (45.6%). Intraoperative assessment of the severity of tricuspid valve incompetence correlated 72% of the time with the preoperative angiographic assessment, in those patients with more severe degrees of incompetence (grade 3+ or 4+), p (X 2) less than 0.001. Increasing severity of preoperative angiographic triscuspid valve incompetence was associated with the requirement for TVR (vs. repair), p (X 2) = 0.0002. In conclusion, preoperative right ventricular angiography is a useful method for assessing tricuspid valve function and may predict the requirement for TVR in patients undergoing tricuspid valve surgery.     

Sleep disorders and depression due to menopausal symptoms in middle-aged Korean females

[Purpose] The purpose of this study was to identify the differences in the incidence of sleep disorders and depression in postmenopausal middle-aged females in South Korea. [Participants and Methods] This study was a cross-sectional study. A total of 87 middle-aged females between the ages of 40 and 60 years were selected through convenience sampling. The data were collected with a self-reported questionnaire from May 1 to May 29, 2017. [Results] The mean menopause score of the study was 5.37. The menopause symptoms indicated significant differences in sexual life. The association between the incidence of menopausal symptoms and sleep disorders and depression scores based on a scale of 1 to 10 was analyzed. Menopausal symptoms strongly affected sleep and depression in middle-aged females. [Conclusion] The findings of this study may be useful in understanding depression and sleep disorders in middle-aged females and for developing more specific programs for depression and sleep disorders. Management strategies are also needed.     

A Case of Cerebellar Infarction Caused by Acute Subclavian Thrombus Following Minor Trauma

Subclavian steal syndrome caused by an acute thrombus is very rare. We present a case of cerebellar infarction with proximal subclavian artery thrombosis. A 56-year-old woman was admitted for sudden vertigo. One day prior to admission, she received a shoulder massage comprised of chiropractic manipulation. On examination, her left hand was pale and radial pulses were absent. Blood pressure was weak in the left arm. Downbeat nystagmus and a right falling tendency were observed. Brain MRI showed multiple acute infarctions in the left cerebellum. The findings of Doppler ultrasonography in the left vertebral artery were compatible with a partial subclavian artery steal phenomenon. Digital subtraction angiography demonstrated a large thrombus in the left subclavian artery. After heparin infusion, thrombus size markedly decreased. Cerebellar infarction caused by acute subclavian thrombosis following minor trauma is rare, but the thrombus can be successfully resolved with anticoagulation.

The effects of computer-assisted cognitive rehabilitation on Alzheimer’s dementia patients memories

[Purpose] The purpose of the present study was to conduct Computer-Assisted Cognitive Rehabilitation (COMCOG) to examine the effects of COMCOG on Alzheimer’s dementia patients’ memories. [Subjects] Thirty-five patients diagnosed with Alzheimer’s dementia received COMCOG for 30 minutes per day, five days per week for four weeks. [Methods] Before and after the COMCOG intervention, subjects’ cognitive functions were evaluated using the Cognitive Assessment Reference Diagnosis System (CARDS) and Mini-Mental State Examination-Korea (MMSE-K) test. [Results] According to the results of the evaluation, among the CARDS scores of the subjects who received COMCOG, the scores of the delayed 10-word list, delayed 10-object list, recognition 10-object, and recent memory significantly increased while the scores of recognition 10-word significantly decreased after intervention compared to before intervention. In addition, among the MMSE-K items, the orientation, registration, and recall showed significant increases. [Conclusion] Based on these results, delay in the progress of memory deterioration can be expected when COMCOG is conducted for Alzheimer’s dementia patients who show declines in cognitive functions.Key words: Alzheimer’s, Computer-Assisted Cognitive Rehabilitation, Memory
