Direct carotid cavernous fistula (CCF), which is an abnormal communication between the intracavernous carotid artery and the cavernous sinus, is a very rare condition that is generally associated with head trauma, intracavernous aneurysms, and certain connective-tissue diseases. The case of a patient with an infarction in the anterior choroidal artery territory is described herein. Cerebral angiography was performed during consecutive workups to investigate the discrepancy between the magnetic resonance angiography data. An unexpected direct CCF of the ipsilateral side of the infarction was found. It is possible that the CCF had influenced the development of the infarction in the anterior choroidal artery territory.

PURPOSE: Initial orthostatic hypotension is typically associated with active standing and normal autonomic function. Some adolescents in the present study displayed initial orthostatic hypotension during passive tilting, and we hypothesized that this condition was due to abnormal autonomic function. METHODS: The present study compared autonomic functioning in two groups of adolescents: patients with a diagnosis of initial orthostatic hypotension according to the tilt table test and patients with typical symptoms of initial orthostatic hypotension but normal tilt table test results. RESULTS: Significantly higher total composite autonomic severity scores and considerably higher adrenergic index were noted in the tilt table tested group. CONCLUSION: Initial orthostatic hypotension is possibly associated with autonomic dysfunction, especially abnormal vasoconstrictive ability, in individuals diagnosed with a tilt table test. Clinicians should take note of autonomic function when performing diagnoses of initial orthostatic hypotension using the tilt table test.

PURPOSE: This study was performed to evaluate the compliance with, and adequacy of, the Korean national guidelines which had been recommended until 2011 for isolation of patients with group 1 nationally notifiable infectious diseases (NNIDs), namely cholera, typhoid fever, paratyphoid fever, shigellosis, and enterohemorrhagic Escherichia coli (EHEC) infection. MATERIALS AND METHODS: We evaluated the clinical and microbiological characteristics of confirmed cases of group 1 NNIDs and compliance with the guidelines in 20 Korean hospitals nationwide in 2000-2010. We also compared the Korean guidelines with international guidelines. RESULTS: Among 528 confirmed cases (8 cases of cholera, 232 of typhoid fever, 81 of paratyphoid fever, 175 of shigellosis, and 32 EHEC infections), strict compliance with the Korean guideline was achieved in only 2.6% to 50.0%, depending on the disease. While the Korean guidelines recommend isolation of all patients with group 1 NNIDs, international guidelines recommend selective patient isolation and screening for fecal shedding, depending on the type of disease and patient status. CONCLUSION: Compliance with the previous national guidelines for group 1 NNIDs in Korea was generally very low. Further studies are needed to evaluate whether compliance was improved after implementation of the new guideline in 2012.

The purpose of this study was to establish a prediction rule for severe illness in adult patients hospitalized with pandemic influenza A (H1N1) 2009. At the time of initial presentation, the baseline characteristics of those with severe illness (i.e., admission to intensive care unit, mechanical ventilation, or death) were compared to those of patients with non-severe illnesses. A total of 709 adults hospitalized with pandemic influenza A (H1N1) 2009 were included: 75 severe and 634 non-severe cases. The multivariate analysis demonstrated that altered mental status, hypoxia (PaO2/FiO2 < or = 250), bilateral lung infiltration, and old age (> or = 65 yr) were independent risk factors for severe cases (all P < 0.001). The area under the ROC curve (0.834 [95% CI, 0.778-0.890]) of the number of risk factors were not significantly different with that of APACHE II score (0.840 [95% CI, 0.790-0.891]) (P = 0.496). The presence of > or = 2 risk factors had a higher sensitivity, specificity, positive predictive value and negative predictive value than an APACHE II score of > or = 13. As a prediction rule, the presence of > or = 2 these risk factors is a powerful and easy-to-use predictor of the severity in adult patients hospitalized with pandemic influenza A (H1N1) 2009.
