PURPOSE: The purpose of this study is to report clinical and radiographic results over a period of two 2 years after cementless total hip arthroplasty (THA) with fourth generation ceramic-on-ceramic articulation. MATERIALS AND METHODS: We studied 22 patients, 23 cases which were followed up for two years among 25 patients, 26 patients who underwent cementless THA with the fourth generation ceramic between April 2009 and December 2009. The average age of the patients was 55.9 years old(22 to 72 years old), and the average follow-up duration was 28 months(24 to 32 months). A clinical evaluation was performed using the Harris hip score (HHS), and radiologic evaluation was based on acetabular cups and osteolysis of the femoral stems, instability, distance, angle, and so on. RESULTS: HHS showed an increase, from 54 for before-surgical treatment, to 91 at the last follow-up. Inguinal pain was observed in one case, and femoral pain was observed in two cases. Stable fixation was achieved in all cases, and no instability, osteolysis, or movement of acetabular cups and femoral stems was observed. CONCLUSION: Clinical and radiological short-term results for use ofthe fourth generation ceramic-on-ceramic cementless THA have favorable so far. Further follow-up study should be performed for evaluation of the long-term results.

Extramedullary relapse of childhood acute lymphoblastic leukemia (ALL) occurs most commonly in the central nervous system or in the testes. Isolated relapse on chest wall as a soft tissue mass is extremely rare in children with ALL. We experenced a 12-year-old girl who developed an isolated relapse on chest wall during the treatment for ALL. She had a pain and protruding mass on right anterior chest wall 6 months after the initial diagnosis of ALL. Imaging study revealed an 5 7 cm sized soft tissue mass on the right chest wall. Histopathologic examination revealed infiltrates composed of immature lymphoblasts with morphology identical with that of previous bone marrow aspiration. Studies on bone marrow and cerebrospinal fluid were negative for disease at this time. The patient was treated with 3,000 cGy of local irradiation in 10 fractions and systemic chemotherapy with ifosfamide and etoposide. The mass size decreased markedly, but she has been suffering from development of multiple mass in other site and recurrent pleural effusion.

We present a patient who complained of excessive daytime sleepiness (EDS), which started three years ago. She had no other medical, neurological, and psychiatric disorders. Nocturnal polysomnography did not indicate any sleep disorders, which might cause daytime EDS, such as obstructive sleep apnea. The following multiple sleep latency test was not compatible for narcolepsy. Her laboratory findings were remarkable for subclinical hypothyroidism, although free T4 and T3 were within reference rage, she had elevated thyroid stimulating hormone. After four weeks of levothyroxine treatment, her EDS resolved. The hypersomnolence, as a presenting symptom of subclinical hypothyroidism, was optimally treated after thyroid hormone replacement.

BACKGROUND: The existing data indicate that obstructive sleep apnea syndrome contributes to the development of cardiovascular dysfunction such as systemic hypertension and cardiac arrhythmias, and the cardiovascular dysfunction has a major effect on high long-term mortality rate in obstructive sleep apnea syndrome patients. To a large extent the various studies have helped to clarify the pathophysiology of obstructive sleep apnea, but many basic questions still remain unanswered. METHOD: In this study, the influence of obstructive sleep apnea on systemic blood pressure, cardiac rhythm and urinary catecholamines concentration was evaluated. Over-night polysomnography, 24-hour ambulatory blood pressure and EGG monitoring, and measurement of urinary catecholamines, norepinephrine (UNE) and epinephrine (UEP), during waking and sleep were undertaken in obstructive sleep apnea syndrome patients group (OSAS, n=29) and control group (Gontrol, n=25). RESULTS: 1) In OSAS and Control, UNE and UEP concentrations during sleep were significantly lower than during waking (P<0.01). In UNE concentrations during sleep, OSAS showed higher levels compare to Control (P<0.05). 2) In OSAS, there was a increasing tendency of the number of non-dipper of nocturnal blood pressure compare to Control (P=0.089). 3) In both group (n=54), mean systolic blood pressure during waking and sleep showed significant correlation with polysomnographic data including apnea index (Al), apnea-hypopnea index (AHI), arterial oxygen saturation nadir (SaO2 nadir) and degree of oxygen desaturation (DOD). And UNE concentrations during sleep were correlated with Al, AHI, SaO2 nadir, DOD and mean diastolic blood pressure during sleep. 4) In OSAS with AI>20 (n=14), there was a significant difference of heart rates before, during and after apneic events (P<0.01), and these changes of heart rates were correlated with the duration of apnea (P<0.01). The difference of heart rates between apneic and postapneic period (deltaHR) was significantly correlated with the difference of arterial oxygen saturation between before and after apneic event (deltaSaO2) (r=0.223, P<0.001). 5) There was no significant difference in the incidence of cardiac arrhythmias between OSAS and Control. In Control, the incidence of ventricular ectopy during sleep was significantly lower than during waking. But in OSAS, there was no difference between during waking and sleep. CONCLUSION: These results suggested that recurrent hypoxia and arousals from sleep in patients with obstructive sleep apnea syndrome may increase sympathetic nervous system activity, and recurrent hypoxia and increased sympathetic nervous system activity could contribute to the development of cardiovascular dysfunction including the changes of systemic blood pressure and cardiac function.

BACKGROUND AND OBJECTIVES: Blood neutrophil-to-lymphocyte ratio (NLR) has been reported to have poor prognostic impact in variable malignancies. However, studies evaluating the clinical significance of blood NLR in patient with papillary thyroid carcinoma (PTC) has been relatively rare, and the outcomes were inconsistent. In this study, we sought to analyze the clinical value of NLR in patients with PTC who had cervical lymph node metastasis. MATERIALS AND METHODS: Retrospective chart review was conducted with 174 patients with confirmed neck metastasis of PTC after initial thyroidectomy. Blood NLR was estimated by dividing the absolute number of blood neutrophil with that of lymphocyte. Statistical analysis was conducted to evaluate correlation between NLR and clinicopathologic factors, patterns of metastatic lymph nodes, and recurrence. RESULTS: Higher NLR (>1.74) was correlated to younger age of patients ( < 45 years, p=0.045) and smaller size of tumor ( < 1 cm, p=0.017). Blood NLR had no impact on patterns of lymph node metastasis or recurrence. CONCLUSION: Blood NLR may not be considered as a predictive factor for clinical aggressiveness or prognosis in patients with PTC with lymph node metastasis.

OBJECTIVE: To investigate the effect of virtual reality (VR) and a tetra-ataxiometric posturography (Tetrax) program on stroke patients with impaired standing balance. METHODS: Thirty acute stroke patients with impaired standing balance were recruited and randomly assigned to a VR, Tetrax, or control group. All patients received conventional balance training as a baseline; and VR and Tetrax patients received VR or Tetrax treatment, in addition. The primary outcome measures to evaluate the overall standing balance were the Berg Balance Scale (BBS) and the falling index (FI). The secondary outcome measures were the stability index (SI) and the weight distribution index (WDI), which were used to evaluate the balance status according to specific body positions. The FI, SI, and WDI were measured using the Tetrax instrument. RESULTS: The BBS and FI scores were improved in all groups, with no significant differences between groups. In open-eyed positions, the VR group showed significantly greater improvement in SI and WDI scores than the control group (p<0.017). In closed-eyed positions, the Tetrax group showed significantly greater improvement in SI and WDI scores than the control group (p<0.017). CONCLUSION: The inclusion of VR and Tetrax programs did not lead to an overall benefit in balance. VR and Tetrax did, however, demonstrate a benefit in specific positions. A Tetrax program may benefit patients with abnormal proprioceptive function, whereas a VR program may benefit patients with normal sensory function.
