PURPOSE: This study was conducted to examine the relationships between the recurrence of pneumothorax with demographic and health-related risk factors. METHODS: Demographic factors (age and gender) and health-related risk factors (Body Mass Index, smoking, exercise, stress, fatigue, and morbidity from colds) were measured from 60 patients admitted to two acute care institutions due to pneumothorax. RESULTS: The study results showed significant differences in factors such as height and minutes of performing exercise per week, between the first occurrence and recurrence groups. However, other risk factors did not show significant differences between the two groups. CONCLUSION: Prevention of recurrences is important for the treatment and management of pneumothorax. More studies are required to accumulate empirical evidence for health-related risk factors and pneumothorax recurrence, as the relationship between all factors and recurrence were not obtained by the study results.

Isaacs' syndrome is a rare and heterogeneous syndrome of continuous muscle fiber activity that originates from peripheral nerves. We report a 56-year-old male patient who showed symptoms of Isaacs' syndrome after the removal of a malignant thymoma. Needle electromyography revealed spontaneously occurring repetitive myokymic discharge in the affected muscles. Acetylcholine receptor (AChR) antibodies were significantly elevated, but clinical and electrophysiologic findings did not indicate the presence of myasthenia gravis. We deduce that in Isaacs' syndrome, raised AChR antibodies may facilitate rather than inhibit cholinergic action.

Congenital ocular motor apraxia is a rare syndrome characterized by rotational head thrusts that attempt to compensate for the lack of voluntary eye movements. We describe the clinical, oculographic and magnetic resonance imaging features of two children with congenital ocular motor apraxia.

BACKGROUND: Methyl bromide is toxic to the central and peripheral nervous systems. Two patients with occupational exposure to this agent are described. CASE: Two cases of previously healthy young men were involved. They had worked in a fumigating plant spraying fruits using methyl bromide for several months before admission. They showed general weakness, severe ataxia, bilateral dysmetria and bilateral lateral gaze limitation. And gaze-evoked nystagmus was observed in one of them. Brain MRI showed symmetrically increased signal intensity lesions including the brainstem, cerebellum and splenium of corpus callosum. After conservative treatment, they gradually improved over the next few weeks. CONCLUSIONS: Symmetry and topography of our patients??clinical and radiographic abnormalities support the proposal that methyl bromide exposure can produce symptoms similar to Bickerstaff's brainstem encephalitis.

We experienced a case of MRKH syndrome in a 24-year-old female which was combined with sacral agenesis, neurogenic bladder, and duplicated ureter associated with vesicoureteral reflux in the right side.

BACKGROUND: To evaluate the characteristics of the co-authorship and its network within the Korean Pathologists' Society. METHODS: In the KoreaMed database, 11,420 articles and 72,478 authors from 1991 to 2010 were searched. The patterns of co-authorship of the authors and institutions were analyzed to build a network matrix. The network centrality indices were measured with UCINET 6.0 and sociogram, and were drawn with Netdraw 5.0. KeyPlayer 1.44 was used for key player analysis. RESULTS: The number of articles that pathologist participated in increased; however, the number of articles that the pathologists are the first author did not increase. The centrality degrees from 1991 to 2010 were 4.16% and 0.3% for the institutions and authors network, respectively. From 1991 to 2000, Seoul National University had the highest degree of centrality and was a key player. However, from 2001 to 2010, Ulsan replaced the position. For the authors, Chi, Je Geun was highest centrality author and key player during the 1991 to 2000 time period. From 2001 to 2010, Yoo, Jinyoung had the highest degree of centrality and Kim, Na Rae was a key player. Overall, most of the centrality indices were occupied by only a few institutions and authors. CONCLUSIONS: The network among the pathologist society is a typical small world society.
