Two cases of traumatic bilateral anterior and posterior dislocation of hip are reported. Dislocations were developed by a traffic accident as a passenger injury in truck. In both cases, the fractued femoral heads appeared posteriorly dislocated on x-ray examination and one of them was removed through posterior approach. Primary arthroplasty for operated hip was not attempted because the patient was young and the defect seemed to be unrelated to weight bearing surface. Extreme rarity of its incidence and curious uncertain mechanism of injury urge to report these cases.

Previous studies showed that whole body vibration could prevent bone resorption and stimulate new bone formation. The aim of this study is to detect and track effect of whole body vibration for osteoporotic bone of OVX rats. 12 Female rats were used and allocated into 5 group, CON, SHAM, WBV 17, WBV 30 and WBV 45. Rats except SHAM group were ovariectomised to induce osteoporosis. Rats in WBV groups were stimulated whole body vibration at magnitude of 1 mm(peak-peak) and frequency 17 Hz, 30 Hz and 45 Hz, repectively, for 8 weeks (20 min, 5 days/week). The 4th lumbar in rats were scanned at a resolution of 35 micrometer at baseline, before stimulation, and 8 weeks by In-vivo Micro-CT. To detect and track changes of morphological characteristics in lumbar trabecuar bone of rats, structural parameters were measured and calculated from acquiring images. In the results, changes of structural characteristics of WBV group were smaller than those of CON group. Loss of quantity of trabecular bone in WBV 45 was the least. In contrast, that in WBV 17 was the biggest. These results showed that reasonable whole body vibration beneficially affected osteoporotic bones. In addition to, whole body vibration was likely to be substituted partly for drug treatment.

Objective: The purpose of this study was to examine whether attachment insecurity, stigma, and certain demographic and medical factors predict depression and anxiety in people living with HIV (PLWH). Methods: Participants were 147 PLWH who visited the outpatient infection clinic in Kyungpook National University Hospital (KNUH; Daegu, South Korea) between June 2020 and January 2021. We measured HIV-related stigma, attachment anxiety and avoidance, depressive symptoms, and anxiety symptoms. Results: Logistic regression analysis showed that unemployment, longer time receiving antiretroviral therapy, higher attachment avoidance, and higher attachment anxiety were significant predictors of depression. Results also showed that longer time receiving antiretroviral therapy, higher attachment anxiety, and concern with public attitudes were significant predictors of anxiety. Conclusion In addition to education to reduce public stigma, interventions to reduce PLWH’s self-stigma should continue. We suggest attachment-based psychotherapy as an effective intervention to improve PLWH’s mental health.

Recently, we experienced two cases of tuberous sclerosis, in 4-year-4-month-old female and 17-month-old male patient. The diagnoses were established by typical clinical manifestations and brain CAT. Especially, in latter case, calcific density was successfully detected by brain CAT, while plain radiographs of the skull revealed still no evidence of calcification. A brief review of related literatures was made.

Hepatocellular cell carcinoma (HCC) is one of the most common and malignant neoplasm in the world. Waldenstrom's macroglobulinemia (WM) is a rare B-lymphocyte neoplasia characterized by monoclonal production of IgM Igs and by a marrow containing a diffuse infiltrate of plasmocytoid lymphocytes. A 67-year-old man was admitted because of multiple site pain, especially right flank and posterior neck pain. Physical examination showed hepatomegaly. Laboratory findings were as follows; total protein 8.6 g/dL, albumin 3.1 g/dL with monoclomal protein(IgM-lamda). Hepatitis C virus(HCV) infection was detected by polymerase chain reaction(PCR). Computed tomography and celiac angiography disclosed HCC. Aspiration biopsy of the liver revealed HCC. Magnetic resonance imaging showed compression fracture and epidural mass in cervical spines. Bone marrow examination revealed normocellularity with an increase of lymphoplasmacytic series. He was diagnosed as having WM and HCC. HCC is frequently associated with other malignancies. As the site of the extrahepatic primary cancer, the stomach ranked first. WM is also known for its association with an increased incidence of a second neoplasm, most of which are less differentiated lymphomas. but an association with a non-lymphoreticular malignancy is quite rare. We report first case of synchronous HCC with bone metastasis and WM (IgM,lamdatype) in korean with chronic hepatitis C.

OBJECTIVE: Endovascular treatment is one of the most important treatments along with open craniotomy for cerebrovascular surgery. The successful treatment of endovascular disease relies on appropriate instruments and the surgeon's skill. Endovascular treatment needs to provide safe and stable access to the catheter cavity. Additionally, it is important to maintain a round shape without changing to an oval shape. The catheter for endovascular treatment has to be flexible and accommodate at least 0.027 inches of inner diameter. The 6-Fr Navien™ Intracranial Support Catheter (formerly the ReFlex Intracranial Catheter; Covidien Vascular Therapies, Mansfield, MA, USA) provides 0.072 inches of inner diameter. MATERIALS AND METHODS: We reviewed 61 cases for 56 cases of endovascular treatment with a Navien catheter. A triaxial system was used for all procedures with femoral arterial access. The Navien catheter was placed in the petrous segment of the internal carotid artery or third segment of the vertebral artery. The patients had various shapes of intracranial arteries, including tortuous vessels. RESULTS: The Navien catheter was used for 61 cases of endovascular treatment. We had 59 cases of coil embolization at unruptured and ruptured aneurysms and two cases of stent insertion into the middle cerebral artery. All the cases were successful without any catheter-related complications. CONCLUSION: The Navien catheter is a recently developed catheter that has several strengths compared with previously developed catheters. It provides a more stable environment for endovascular treatment. It provides a cavity sufficient for endovascular treatment devices. Additionally, it is sufficiently flexible to approach tortuous vessels.

OBJECTIVE: Researchers and clinicians have been unable to fully elucidate the natural course of and proper treatment for unruptured intracranial aneurysms (UIAs) smaller than or equal to 5 mm, particularly with regard to whether close observation or surgery is more appropriate. In this retrospective study, we evaluated the safety and efficacy of endovascular coil embolization of small (≤ 5 mm) asymptomatic UIAs by analyzing outcomes and complications associated with the procedure. MATERIALS AND METHODS: We analyzed data from 150 patients with small asymptomatic UIAs (≤ 5 mm) treated with coil embolization between January 2011 and December 2015. Three-dimensional angiography was used to measure aneurysm size. We evaluated procedure-related morbidity and mortality, immediate post-operative angiographic results, brain computed thomography follow-up results on post-operative day one, and clinical progress. RESULTS: UIAs occurred primarily in the anterior circulation area (142 cases, 94.67%), though eight patients exhibited UIAs of the posterior circulation. Following coil embolization, aneurysms with complete occlusion were observed in 137 cases (91.3%). Partial occlusion occurred in five cases (3.33%), while the procedure had failed in eight cases (5.33%). Procedure-related morbidity and mortality were five cases (3.33%) and zero cases, respectively. CONCLUSION: The endovascular treatment of small asymptomatic UIAs is associated with good short-term outcomes without permanent neurologic complications as well as low overall complication and morbidity rates. Thus, the procedure should be considered for patients with smaller asymptomatic UIAs.

Encapsulated acute subdural hematoma (ASDH) has been uncommonly reported. To our knowledge, a few cases of lentiform ASDH have been reported. The mechanism of encapsulated ASDH has been studied but not completely clarified. Encapsulated lentiform ASDH on a computed tomography (CT) scan mimics acute epidural hematoma (AEDH). Misinterpretation of biconvex-shaped ASDH on CT scan as AEDH often occurs and is usually identified by neurosurgical intervention. We report a case of an 85-year-old man presenting with a 2-day history of mental deterioration and right-sided weakness. CT scan revealed a biconvex-shaped hyperdense mass mixed with various densities of blood along the left temporoparietal cerebral convexity, which was misinterpreted as AEDH preoperatively. Emergency craniectomy was performed, but no AEDH was found beneath the skull. In the subdural space, encapsulated ASDH was located. En block resection of encapsulated ASDH was done. Emergency craniectomy confirmed that the preoperatively diagnosed AEDH was an encapsulated ASDH postoperatively. Radiologic studies of AEDH-like SDH allow us to establish an easy differential diagnosis between AEDH and ASDH by distinct features. More histological studies will provide us information on the mechanism underlying encapsulated ASDH.
