Cranial nerve palsies are relatively common after trauma, but trochlear nerve palsy is relatively uncommon. Although traumatic trochlear nerve palsy is easy to diagnose clinically because of extraocular movement disturbances, radiologic evaluations of this condition are difficult to perform because of the nerve's small size. Here, we report the case of a patient with delayed traumatic trochlear nerve palsy associated with a traumatic subarachnoid hemorrhage (SAH) and the related radiological findings, as obtained with high-resolution three-dimensional (3D) magnetic resonance imaging (MRI). A 63-year-old woman was brought to the emergency room after a minor head trauma. Neurologic examinations did not reveal any focal neurologic deficits. Brain computed tomography showed a traumatic SAH at the left ambient cistern. The patient complained of vertical diplopia at 3 days post-trauma. Ophthalmologic evaluations revealed trochlear nerve palsy on the left side. High-resolution 3D MRI, performed 20 days post-trauma, revealed continuity of the trochlear nerve and its abutted course by the posterior cerebral artery branch at the brain stem. Chemical irritation due to the SAH and the abutting nerve course were considered causative factors. The trochlear nerve palsy completely resolved during follow-up. This case shows the usefulness of high-resolution 3D MRI for evaluating trochlear nerve palsy.

Carpal tunnel syndrome(CTS), the most common compressive neuropathy, is usually diagnosed by clinical features and nerve conduction test(NCS). However, NCS might show no abnormal finding. Ultrasonography(USG), known as helpful adjunctive in diagnosis of CTS, also might show false negative finding. A 33-year-old woman presented with complaints of pain and numbness in median nerve area on her right hand for 4 years. Despite typical clinical features of CTS, neither NCS nor USG showed abnormal finding. Because of persistent symptom, without significant improvement on conservative management, endoscopic carpal tunnel release(ECTR) was performed with carpal tunnel pressure(CTP) measurement. The measured CTP was 27.9mmHg before ECRT, which was reduced to 5.9mmHg after operation. The pain and numbness subsided after operation. Our case showed the usefulness of CTP measurement in diagnosis of CTS. The measurement of CTP might be an important diagnosis modality for some patients having CTS, especially in cases without definitive findings in NCS and USG.

OBJECTIVE: Adequate management of increased intracranial pressure (ICP) is critical in patients with traumatic brain injury (TBI), and decompressive craniectomy is widely used to treat refractory increased ICP. The authors reviewed and analyzed complications following decompressive craniectomy for the management of TBI. METHODS: A total of 89 consecutive patients who underwent decompressive craniectomy for TBI between February 2004 and February 2009 were reviewed retrospectively. Incidence rates of complications secondary to decompressive craniectomy were determined, and analyses were performed to identify clinical factors associated with the development of complications and the poor outcome. RESULTS: Complications secondary to decompressive craniectomy occurred in 48 of the 89 (53.9%) patients. Furthermore, these complications occurred in a sequential fashion at specific times after surgical intervention; cerebral contusion expansion (2.2 +/- 1.2 days), newly appearing subdural or epidural hematoma contralateral to the craniectomy defect (1.5 +/- 0.9 days), epilepsy (2.7 +/- 1.5 days), cerebrospinal fluid leakage through the scalp incision (7.0 +/- 4.2 days), and external cerebral herniation (5.5 +/- 3.3 days). Subdural effusion (10.8 +/- 5.2 days) and postoperative infection (9.8 +/- 3.1 days) developed between one and four weeks postoperatively. Trephined and post-traumatic hydrocephalus syndromes developed after one month postoperatively (at 79.5 +/- 23.6 and 49.2 +/- 14.1 days, respectively). CONCLUSION: A poor GCS score (< or = 8) and an age of > or = 65 were found to be related to the occurrence of one of the above-mentioned complications. These results should help neurosurgeons anticipate these complications, to adopt management strategies that reduce the risks of complications, and to improve clinical outcomes.

BACKGROUND AND OBJECTIVES: Atrioventricular plane displacement (AVPD) has been used for evaluating systolic function. However, its relations with other echocardiographic variables reflecting diastolic function are not well documented. This study was designed to assess the relations between AVPD and those echocardiographic variables known to reflect diastolic function, especially using mitral annulus velocity. SUBJECTS AND METHODS: Eighty-seven patients with normal left ventricular (LV) systolic function (normal echocardiography group (Group I, n=44), concentric left ventricular hypertrophy (LVH) group (Group II, n=43)) and 51 patients with LV dysfunction (Group III) were studied. To evaluate the correlation with echocardiographic variables reflecting LV systolic and diastolic function, we measured mitral inflow velocity and mitral annulus Doppler tissue velocity. RESULTS: AVPD was correlated negatively with age, the ratio of early diastolic mitral inflow velocity and early diastolic mitral annulus velocity (E/E'), isovolumic relaxation time, and E/A ratio. AVPD was correlated positively with deceleration time, ejection fraction, and systolic mitral annulus velocity (S'). By multivariate analysis, AVPD was independently correlated with S' (beta=0.4, p<0.001) and E' (beta=0.5, p<0.001) in the normal LV function group, and with S' (beta=0.6, p<0.001) and E/E'(beta=-0.3, p=0.005) in the LV dysfunction group. CONCLUSION: AVPD may be used as a diagnostic tool for evaluating LV diastolic function.

OBJECTIVES : The aims of this study are to estimate the prevalence of the DSM-IV psychiatric disorders in the Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI), and to compare those with previous studies. METHODS : The Korean Epidemiologic Catchment Area study Replication (KECA-R) was conducted between August 2006 and April 2007. The sampling of the subjects was carried out across 12 catchment areas. A multistage, cluster sampling design was adopted. The target population included all eligible residents aged 18 to 64 years. Face-to-face interviews were conducted with the Korean version of Composite International Diagnostic Interview (K-CIDI) based on the DSM-IV (N=6,510, response rate=81.7%). RESULTS : A total of 6,510 participants completed the interview. The lifetime and 12-month prevalence rates for all types of DSM-IV disorders were 30.0% and 17.3%, respectively. Those of specific disorders were as follows : 1) alcohol use disorder, 16.2% and 5.6% ; 2) nictotine use disorder, 9.0% and 6.0%;3) specific phobia, 3.8% and 3.4%;4) major depressive disorder, 5.6% and 2.5% ; and 5) generalized anxiety disorder, 1.6% and 0.8%. Data relating to nicotine and alcohol use disorder revealed a very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among females than males. CONCLUSION : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in the distribution of psychiatric disorders across the country and times were observed.
