Primary osteomyelitis of the clavicle is an uncommon disease and usually hematogeneous in its origin associated with risk factors such as drug abuse, rheumatoid arthritis, diabetes mellitus and prolonged hemodialysis. We report 60-year-old man with osteomyelitis of the clavicle after subclavian vein catheterization. He visited with a history of painful swelling at left sternoclavicular joint area for a month. He had a subclavian vein catheterization history at left side when he admitted due to right spontaneous pneumothorax 5 weeks ago. On admission, ESR and CRP levels were elevated but radiologic findings were normal. Bone scanning showed increased uptake on medial portion of clavicle. MRI findings revealed signal changes of clavicle and surrounding soft tissues. Curettage was performed. Pathologic reports correlated with chronic osteomyelitis.

OBJECTIVES: The attentional deficit is a core symptom in attention deficit hyperactivity disorder. The major brain areas related to attention are frontal and parietal lobes. Abnormalities of frontal and parietal lobes in attention deficit hyperactivity disorder have been reported in previous researches. But, most of the researches are based on comparing patients and controls while they are in resting condition. Further research on funtional changes related to performance of attentional task is needed to understand the attentional dysfuntion in attention deficit hyperactivity disorder. In this study, the localized functional changes of the brains related to attentional task in patients with attention deficit hyperactivity disorder and the differences of them between patients and normal controls were examined. Also the effect of the methylphenidate on functional changes related to attentional task in patients with attention deficit hyperactivity disorder was examined. METHOD: Quantitative electroencephalography (QEEG) was applied to examine the fuctional changes related to attentional task. Subjects of this study consisted of 20 patients with attention deficit hyperactivity disorder and 20 controls who were matched age, sex, handedness, intelligence. QEEG was recorded on eye open resting condition, and on performing computerized attentional task. In cases of patients, after taking of methylphenidate, QEEG was recorded on both conditions. RESULTS: 1)In attention test, normal controls had better scores in response time and variabilities of response time than those of patients with attention deficit hyperactivity disorder without taking methylphenidate. After taking medication, scores of omission, response time and variabilities of response time were significantly improved, comparing to scores without taking medication. No differences were recognized between the controls and patients with taking medication in scores of attention test. 2)In resting condition, spectral EEG revealed baseline activity levels of patients were significantly increased comparing to those of controls. 3)Analysis of delta wave revealed that amplitudes of controls were significantly elevated in parieto-occipital area during performance of attentional task. But in patients, localized activated area related to attentional task was not remarkable. 4)Theta activity of controls were significantly elevated in right frontal, right temporal, and both parieto-occipital areas during performance of attentional task. But in patients without taking medication, localized activated area related to attentional work was not remarkable. After taking medication, right frontal, right temporal, and both parieto-occipital areas were significantly activated. 5)Alpha activities of controls were significantly increased in parieto-occipital area during performance of attentional task, but those of patients without taking medication were increased in broad area. 6)Beta activities of controls were significantly increased in frontal area during attentional performance, but those of patients without taking medication were significantly increased in most of the brain areas. After taking medication, significantly increased activities related to attentional task were recognized in left frontal, and both temporal areas. Localized activated patterns similar to those of controls were recognized. CONCLUSION: Based on the results of this research, it is suggested that patients with attention deficit hyperactivity disorder have increased baseline brain activity. In controls, brains showed localized response to a attentional stimuli, and functional changes related to attentional stimuli were recognized in frontal, and parieto-occipital areas. But, patients failed in showing appropriate localized activated response to attentional stimuli. It is concluded that frontal and parieto-occipital areas have some deficit responsible for the attentional dysfunction of attention deficit hyperactivity disorder.

Drugs of the benzodiazepine family pharmacologically have superior anti-anxiety, sedative, anti-convulsant, and muscle relaxant effect resulting in its popular use not only in psychiatry but in other field of medicine. However, the long term use of benzodiazepines may cause to question the efficacy and may amount to dependence, tolerance, and withdrawal symptoms thus leading to sociologic problems. The treatment strategies of benzodiazepine dependence consist of gradual dosage reduction, the substitution to a long half-life benzodiazepine, and providing psychological support. We present two treatment experiences of high dose lorazepam dependence along with the review of corresponding literature.

High tension electrical burns affecting the wrist are likely to produce full thickness necrosis of the skin and to damage deep vital structures beneath the eschar, affecting he local tendons, nerves, vessels, even bones and joints which result in serious dysfunction of the hand. An aggressive approach to the treatment of these severe wounds and adequate wound coverage are essential for the successful result. From October 1997 to February 2000, we had treated 23 electrical wrist injuries in 20 patients with free flaps. Among these, 13 anterolateral thigh flaps, 5 forearm flaps, 2 scapular flaps, 2 parascapular flaps, and 1 medial leg flap were executed. About 2-4 weeks after initial injury, we tried free flaps. Preoperative debridement was not carried out. At the time of surgery, debridement of all nonviable tissue was done, but nerves, tendons, and bones were left in place with minimal or no debridement when they had anatomic continuity, regardless of their appearance of viability. In all cases, successful soft tissue coverage and wound healing were achieved, and we obtained the following conclusions. 1. Flap coverage should be executed before damage of the tendons, nerves, vessels. 2. As long as the free flap survives, the infected tendons, nerves, and denuded bone can be salvaged. 3. For later reconstruction of the wrist, fasciocutaneous flap should be preferred to promise tendon gliding and endure several operative procedures.

Fascioliasis is a zoonotic disease caused by Fasciola hepatica, a liver fluke, for which human acts as an accidental host. Fascioliasis, while common in some tropical countries, is rare in Korea. Endoscopie retrograde cholangiopancreatography(ERCP) has been described in only a very few cases as a useful technique for the diagnosis of fascioliasis. We report a case of fascioliasis diagnosed by ERCP, after endoscopic sphinchterotomy adult worms were removed by Dormia basket.

Several blood dyscrasias associated with clozapine have been well known to clinicians and potentially life threatening agranulocytosis has been widely reported. However, there is little report regarding incidence, progression and associated features of eosinophilia associated with clozapine. In clinical studies, the onset of eosinophilia usually occurs artier 3 to 5 weeks of treatment and rarely were cases fatal with medical complication. We report the first case of severe eosinophilia, bilateral pleural effusion, asicites, hepatitis and cholecystitis associated with clozapine that would be fatal. Eosinophilia occurred after 19 days of treatment with clozapine and all the clinical conditions improved along with interruption of clozapine treatment. It is suggested that eosinophilia may be more severe side effort than has ether been known and close hematologic monitoring should be done during early treatment of clozapine.
