Lyme disease is a common vector-borne disease caused by Borrelia burgdorferi. Erythema migrans represents the most common manifestation during the early phase of this disease;however, systemic manifestations involving the nervous system, joints, or heart are known to occur. We report a case of Lyme disease accompanied by cardiac complications in a 13-year-old Korean male adolescent. The patient developed annular erythematous lesions on his lower extremities after a field trip during his visit to Connecticut, USA, for a boarding school camp, and his skin lesions were consistent with erythema migrans. Indirect immunofluorescence assay and Western blot analysis for Lyme immunoglobulin M showed positive results. Electrocardiography revealed a first-degree atrioventricular block, and he was diagnosed with Lyme carditis and received a 4-week course of oral doxycycline. Follow-up electrocardiography performed a week later revealed normal findings, and the patient showed an uneventful recovery. Lyme carditis often presents as an asymptomatic heart block that can progress to an advanced heart block; however, this condition is reversible with appropriate antibiotic treatment.

In the last decade Computed Tomography(CT) has played a critical role in the diagnostic evaluation of the patients with focal brain injury. But it is apparent from pathologic studies that CT underestimates the severity of the many forms of cerebral injury such as primary brain stem injury, non-hemorrhagic cortical contusion and diffuse axonal injury(DAI). Magnetic Resonance Imaging(MRI), however, has been shown to be highly sensitive in detecting diffuse brain injury(DBI). Among the consecutive 13 cases of DBI patients in this series for 10 months, twelve patients were verified as MR evidence of injury in prospective studies. The anatomical distribution of the injuries were 11 cases of corpus callosal lesion, 6 cases of lobar white matter lesion, 1 case of primary brain stem lesion. The sensitivities of MR imaging in detecting the primary lesion were 76.9%(10/13) in T1WI and 92.3%(12/13) in T2WI. In DBI, patients with callosal injuries had higher incidence(8/12) than lobar white matter and primary brain stem lesion, the corpus callosal atrophy by midsaggital MR imaging and behavioral seguellae in survivous of severe head injury implicate the corpus callosal injury and degeneration. More accurate detection and delineation of traumatic lesions with MR should permit more accurate prediction of neurologic and cognitive recovery and assist in optimizing form of treatment.

Purpose:
The purpose of this study was to determine the effects of ankle dorsiflexion, neutral, and plantarflexion on lower extremity muscle activity and break point angle (BPA) during Nordic hamstring exercises.
Methods:
Twenty-four members of a college soccer club (age, 21.68±2.39 years; height, 175.63±4.76 cm; weight, 71.88±6.29 kg) were recruited to participate in the experiment, and all subjects were measured three times in triplicate for Nordic hamstrings at three different ankle angles with all subjects in one group. Surface electromyography equipment (miniDTS, Noraxon Inc.) was used to acquire 3 seconds of muscle activity data at the starting point (90°) during exercise, and motion analysis software (Kinovea version 0.9.5, Kinovea) was used to collect kinematic data at the point where knee strike angular velocity exceeded 30°/sec for BPA data acquisition.
Results:
The results of this study, lower extremity muscle activity was not significantly different in the three variants of Nordic hamstring exercises, but BPA was significantly lower in the dorsiflexion position (60.28°±6.35°) compared to the neutral position (65.32°±6.35°) and plantarflexion position (63.82°±7.01°) (p< 0.001).
Conclusion
These results suggest that the dorsi flexion position of the ankle during Nordic hamstring exercises allows the body to maintain the position for a longer period of time against eccentric forces in situations where the body is moving forward. This suggests that the ankle dorsi flexion position can be used as a position for effective Nordic hamstring exercises in amateur soccer players.

OBJECTIVE: To analyze the clinical data and surgical results from symptomatic chronic subdural hematoma (CSDH) patients who underwent burr-hole drainage (BHD) at the maximal thickness area and twist-drill craniostomy (TDC) at the precoronal point. METHODS: We analyzed data from 65 symptomatic CSDH patients who underwent TDC at the pre-coronal point or BHD at the maximal thickness area. For TDC, we defined the pre-coronal point to be 1 cm anterior to the coronal suture at the level of the superior temporal line. TDC was performed in patients with CSDH that extended beyond the coronal suture, as confirmed by preoperative CT scans. Medical records, radiological findings, and clinical performance were reviewed and analyzed. RESULTS: Of the 65 CSDH patients, 13/17 (76.4%) with BHD and 42/48 (87.5%) with TDC showed improved clinical performance and radiological findings after surgery. Catheter failure was seen in 1/48 (2.4%) cases of TDC. Five patients (29.4%) in the BHD group and four patients (8.33%) in the TDC group underwent reoperations due to remaining hematomas, and they improved with a second operation, BHD or TDC. CONCLUSION: Both BHD at the maximal thickness area and TDC at the pre-coronal point are safe and effective drainage methods for symptomatic CSDHs with reasonable indications.
