The authors carried out various treatment modalities in 74 consecutive patients with hypertensive basal ganglionic-thalamic intracerebral hemorrhage and were admitted to the Department of Neurosurgery. Konkuk University Hospital, from Jan. 1991 to Dec. 1993. A variety of prognostic factors that influence mortality were observed. The locaton of hematoma was at the basal ganglia in 47 cases and at the thalamus in 27 cases. The prognosis gets poorer as the hematoma extended wider and deeper. The prognosis was unfavorable when the hematoma was over 30cc(P<0.001). The mortality rate was higher in cases with IVH than in cases without IVH(P<0.005). In cases with IVH, 19 cases(26%) showed dilated 4th ventricular hemorrage and higher mortality rate(P<0.001). Cases in which the GCS were less than 9 on admission showed higher mortality rate(P<0.0001). The mortality rate was also higher if the midline shift was more than 10mm on the initial brain CT scan(P<0.005). THe group where the unilateral or bilateral pupillary light reflex was unreactive(35cases) showed poorer prognosis than the group where the bilateral pupillary light reflex was reactive(P<0.0001). The ventriculocranial ratio(VCR), hydrocephalus, surrounding edema edema around the heamtoam, and treatment modality were not related to the prognosis. The significant prognostic factors in patients with hypertensive basal ganglionic-thalamic intracerebral hemorrhage were location and type of hematoma, whether or not the volume of hematoma is more than 30cc, IVH, dilated 4th ventricular hemorrhage, Graeb's score of more than 7, GCS of less than 9, midline shift of more than 10mm, and reactivity of pupillary light reflex.

STUDY DESIGN: A retrospective study OBJECTIVES: To examine the influence of cervical spondylosis on an acute cervical spinal cord injury. SUMMARY OF LITERATURE REVIEW: There are no reports on the relationship between cervical spondylosis and acute cervical spinal cord injuries. MATERIALS AND METHODS: Twenty six patients who underwent operative treatment for acute cervical injuries with spinal cord injury were evaluated. The mean age and follow-up period was 58 years and 2.2 years, respectively. The evaluation was performed by examining the causes of the injuries, and the classification of fractures according to the presence of cervical spondylosis. This study compared the degrees of postoperative neurological recovery with motor index score in the groups with and without cervical spondylosis. RESULTS: Cervical cord injuries were more prevalent in the group 60 years and older; 17 cases vs. 9 cases in the group under 60 years. Eleven (65%) and 6 (35%) cases in the group 60 years and older had sustained a high and low energy injury, respectively. In contrast, mostly high energy injuries (8 in 9 cases) were encountered in the group under 60 years of age. A low energy injury could cause a acute cervical cord injury in the group 60 years and older, who also had cervical spondylosis. In those cases, previous cervical spondylosis might be one of the etiologic factors. CONCLUSIONS: The cases with cervical spondylosis in the group 60 years and older tended to show incomplete cord injury and good postoperative neurological recovery when they had sustained cervical cord injuries.

Midventricular obstructive hypertrophic cardiomyopathy (MOHCM) is a rare variant of hypertrophic cardiomyopathy. Apical dilatation and myocardial infarction can be complicated without significant coronary artery disease. We report a case of apical dilatation in a patient with MOHCM without atherosclerotic coronary artery disease. A 76-year-old woman was admitted for recent cerebral infarction and consulted to cardiologist for abnormal electrocardiographic findings. She had been suffering from exertional dyspnea (NYHA II) for about four years. Two dimentional-echocardiography revealed midventricular obstructive hypertrophy with an apical dilatation and paradoxical jet flow from the apical aneurysm to the left ventricular outflow tract during early diastole. Cardiac catheterization demonstrated dyskinesia in the apical wall with midventricular obstruction and a peak-to-peak intraventricular pressure gradient of 110 mmHg during pull-back from the apical high-pressure chamber to the subaortic low-pressure chamber in the left ventricle. Coronary angiograms showed no significant stenotic lesion of the coronary arteries. She was prescribed oral beta-adrenergic antagonist to decrease the intraventricular pressure gradient.

BACKGROUND AND OBJECTIVES : The transradial approach has been increasingly used as an alternative to conventional transfemoral intervention. However, there is little data on the efficacy of transradial coronary intervention (TRI) in left main coronary arterial (LMCA) disease. The purpose of this study was to evaluate the feasibility of TRI in selective patients undergoing percutaneous coronary intervention (PCI) for LMCA disease. SUBJECTS AND METHODS : Between Jan 2003 and May 2005, 83 patients with LMCA stenosis were treated with PCI. Of these, 40 selected patients having undergone TRI were included in this study. RESULTS : The patients included 30 males and 10 females, with a mean age of 61+/-12 years. There were 28 cases (70%) involving coronary arteries other than the LMCA and 24 cases (60%) with bifurcation lesion involvement. In 28 cases (70%), a 6 Fr sized guiding catheter was used. No case required crossover from TRI to TFI due to procedural failure. During hospitalization, 2 patients who underwent primary PCI in the setting of STEMI died, but there were no other clinical events. CONCLUSION : In selected patients with LMCA disease, TRI can be a feasible and safe approach for PCI.

STUDY DESIGN: This is a retrospective study. OBJECTIVES: We wanted to clarify the association between the position of the atlantoaxial fusion angle and the change of the subaxial cervical spine alignment (SCA) and the reduction loss after atlantoaxial fusion (AAF) using the posterior wiring technique (PWT), transarticular screw fixation (TAF) and posterior screw-rod fixation (PSR) for treating atlantoaxial instability (AAI). SUMMARY OF LITERATURE REVIEW: There are not many studies on the change of the SCA and the reduction loss after AAF. MATERIALS AND METHODS: Thirty five patients underwent AAF for AAI from 1986 to 2008. The mean follow-up period was 59.5 months. The surgical techniques were divided into three groups, that is, PWT: 17 patients, TAS: 10 and PSR: 8. The causes of instability were transverse ligament rupture in 12 patients, rheumatoid arthritis in 11, Os odontoideum in 6 and nonunion of an odontoid fracture in 6. Plain radiographs were used to assess the atlanto-dental interval, the posterior arch-lamina angle, the change of the SCA and the time of fusion. RESULTS: Fusion was achieved in all the patients within 3.5 months (range: 3-5 months). The radiologic findings in the 5 PWT patients showed a reduction loss and 3 patients showed subaxial cervical kyphosis (SCK). The TAS group had no reduction loss or SCK. The PSR group had no reduction loss and one patient showed SCK. A statistically significant reduction loss and SCK occurred in the group in which there was a posterior arch-laminar angle greater than 10 degrees before and after surgery. CONCLUSIONS: For the treatment of AAI, the position of the AAF is associated with the change of the postoperative SCA. The preoperative lodortic position of C1-2 should be maintained to prevent the change of the SCA.

Cardiac myxomas are the most common benign cardiac tumors and can be associated with systemic embolization including acute myocardial infarction (AMI). The probability of an arterial embolization is closely related to a tumor's villous morphology. In cases of AMI caused by cardiac myxoma, open heart surgery including excision of the coronary artery has been the one of the treatment options for removing the myxoma and embolus from the coronary artery to maintain distal coronary flow. However, preparing for emergent open heart surgery takes a considerable amount of time. Moreover, this time delay can deteriorate the coronary perfusion to the infarcted area and is associated with poor clinical prognosis. So intracoronary catheter aspiration can be an additional option to maintain the distal coronary flow. In this report we present a case with acute anterior ST elevation myocardial infarction caused by a left atrial myxoma. The embolus in the left anterior descending coronary artery was successfully removed with intracoronary catheter aspiration, and distal coronary flow was restored after the procedure.

Background:
and Purpose: Medication adherence is essential for effective medical treatment.However, it is challenging for cognitively impaired patients. We investigated whether an automated telephone reminder service improves medication adherence and reduces the decline of cognitive function in isolated patients with cognitive impairment.
Methods:
This was a single-center, randomized clinical trial. We enrolled mild cognitive impairment (MCI) or Alzheimer’s disease (AD) patients who lived alone or with a cognitively impaired spouse. We provided an automated telephone reminder service for taking medication to the intervention group for 6 months. The control group was provided with general guidelines for taking the medication every month. The participants underwent neuropsychological assessment at the beginning and end of the study. Statistical significance was tested using nonparametric Wilcoxon rank sum and Wilcoxon matched-pairs signed-rank tests.
Results:
Thirty participants were allocated randomly to groups, and data for 29 participants were analyzed. The mean age was 79.6 (standard deviation, 6.0) years and 79.3% of the participants were female. There was no significant difference in medication adherence between the 2 groups. However, a subgroup analysis among participants with more than 70% response rates showed better medication adherence compared to the control group (intervention: 94.6%; control: 90.2%, p=0.0478). There was no significant difference in the change in cognitive function between the 2 groups.
Conclusions
If a patient’s compliance is good, telephone reminders might be effective in improving medication adherence. It is necessary to develop reminder tools that can improve compliance for cognitively impaired patients.

Immune Network 2022;22(3):e28-
The 26S proteasome irreversibly hydrolyzes polyubiquitylated substrates to maintain protein homeostasis; it also regulates immune responses by generating antigenic peptides. An alternative form of the 26S proteasome is the immunoproteasome, which contains substituted catalytic subunits (β1i/PSMB9, β2i/PSMB10, and β5i/PSMB8) instead of constitutively expressed counterparts (β1/PSMB6, β2/PSMB7, and β5/PSMB5). The immunoproteasome expands the peptide repertoire presented on MHC class I molecules. However, how its activity changes in this context is largely elusive, possibly due to the lack of a standardized methodology to evaluate its specific activity. Here, we describe an assay protocol that measures the immunoproteasome activity of whole-cell lysates using commercially available fluorogenic peptide substrates. Our results showed that the most accurate assessment of immunoproteasome activity could be achieved by combining β5itargeting substrate Ac-ANW-AMC and immunoproteasome inhibitor ONX-0914. This simple and reliable protocol may contribute to future studies of immunoproteasomes and their pathophysiological roles during viral infection, inflammation, and tumorigenesis.

Cutaneous squamous cell carcinoma is the second most common tumor in humans, and its incidence is increasing. In cutaneous squamous cell carcinoma, lymph node and distant metastases are rare, and bone invasion in the lower limbs is uncommon. A 67-year-old male presented with a solitary erythematous plaque on the fifth toe, accompanied by swelling. A shave biopsy was performed. The diagnosis of bone-invaded squamous cell carcinoma with aggressive behavior was made by combining the histopathological, immunohistochemical staining, and magnetic resonance imaging results. Mohs micrographic surgery was performed to remove the skin lesion and tumor-invaded bone. However, 2 months later, squamous cell carcinoma relapsed in the same area. After confirming the absence of lymph node metastasis, additional treatment, including ray amputation, was performed. Adjuvant radiotherapy was not administered. We present a rare case of squamous cell carcinoma that relapsed after Mohs surgery and was subsequently treated with ray amputation.
