STUDY DESIGN: A case of brain infarction due to occlusion of vertebral artery after cervical spine fracture is reported. OBJECTIVES: Documentation of possibility and clinical significances of brain infarction as one of grave complications after cervical spine injury. SUMMARY OF LITERATURE REVIEW: Occlusion of vertebral artery and consequent brain infarction can be associated with cervical spine injuries because vertebral arteries course through the transverse foramina from sixth to second corvical vertebrae. Infarction of vertebrobasilar system may cause impairment of cerebral, cerebellar, or brain stem function and can occasionally bring grave functional loss, even death. MATERIALS AND METHODS: A case of occlusion of vertebral artery and consequent cerebral infarction after cervical spine fracture in a 66 year-old man. Brain CT and angiogram were performed. He was managed with anticoagulants. RESULTS: Neurologic deficits from brain infarction disappeared after 2 weeks. CONCLUSIONS: Attention to the possibility of these complications and awareness of their clinical features seem to be mandatory in managing cervical spine injury patients.

BACKGROUND: Single pass lead VDD pacing preserves atrioventricular synchrony with a single lead system which incorporates floating atrial electrodes. The objectives of this study were to measure whether different body postures and physical activities cause significant changes of the atrial electrogram amplitudes and to evaluate the effectiveness of its atrial sensing, ventricular sensing and pacing. METHOD: Prospective study was done in 7 patients with high degree AV block and normal sinus node function in whom a single lead VDD pacing system was implanted. The P wave amplitude was been measured in different condition during follow-up period. RESULTS: 1) During follow-up period, the P wave amplitude showed variation with changes in posture and respiration, but there was no consistent increase or decrease in amplitude. The lowest P wave amplitude was above the minimal atrial sensing value of 0.2 mV. 2) The percentage of atrial synchronous ventricular pacing recorded in Holter ECG and during Treadmill exercise test was more than 99%. 3) Atrial oversensing or VA cross sensing were not observed in any of the patients. CONCLUSIONS: Despite floating atrial electrode, the single pass lead VDD pacing maintains reliable atrial sensing and ventricular pacing in different body position and physical activity, so it may offer an excellent alternative in patients with high grade AV block and intact sinus node function.

We reviewed retrospectively the medical records of 229 cases of tuberculosis, who had been diagnosed clinically and admitted to the departmet of pediatrics, Seoul National Univeristy Children's Hospital, during the period of 6 years from October, 1985, to October, 1991. Patients with tuberculosis occupied 1.2% of the hospitalized patients. Forty-three percent of the patients were under 3 years of age. Principal involvement sites were; the lungs-26.7%, the pleura-18.8%, the central nervous system-30.6%, the abdomen-7.4%, the genito-urinary tract-1.3%, the bones and joints-3.0%, the lymph nodes-3.0%. In 147 patients with extrapulmonary tuberculosis, pulmonary lesions suggestive of tuberculosis were found in 33.3%, 9.2% of the patients had miliary dissemination. In pulmonary tuberculosis and extrapulmonary tuberculosis with lung involvement, the gastric aspirates were positive for acid-fast bacilli (AFB) by Ziehl-Neelson stain in 6.1%, and grew M. tuberculosis in 43.5%. The sputa were positive for AFB in 12.9%, culture in 18,5%. In extrapulmonary tuberculosis, the specimens from involved sites were positive for staining in 5.7%, culture in 19.3%. Twenty-one isolates of M. tuberculosis were submitted to susceptibility to 11 antituberculous drugs. Resistance to one or more drugs were found in 38.1% of the isolates. INH resistance was found in 33.3%, RFP resistance in 28.6%. We conclude that bacteriologic documentation of tuberculosis is possible in significant proportion of the pediatric patients, drug resistance of M. tuberculosis isolated from the children is high in Korea, and continued monitoring of drug resistance is required.

OBJECTIVE: Appropriate evaluation of hypertension is important in the patients with a stroke because hypertension is a major cause of a stroke. Blood pressure may be falsely elevated or depressed immediately after a stroke, depending on the severity of neurological deficit, mobility, and physical activity, and the level of consciousness. To overcome this problem, ambulatory blood pressure monitoring (ABPM) has been proposed as a method of obtaining a more accurate clinical assessment. SUBJECTS AND METHODS: The present study was performed in an acute stage of stroke patients to assess the manifestation of 24 hour ambulatory blood pressure, to observe the nocturnal blood pressure fall and to evaluate the relationship of blood pressure degree on admission and nocturnal blood pressure dip. Thirty four patients admitted within 24 hours after onset of acute stroke were involved in this study. 24 Hour blood pressure monitoring device was installed on an independent arm by oscillometric method as soon as brain imaging study was performed. ABPM readings were obtained each 30 minutes during daytime and each 1 hour during nighttime with electrocardiography. Each patients were classified as the presence or absence of hypertension. We examined nocturnal blood pressure dip and mean pressure of 24 hour ambulatory blood pressure. RESULTS: 1)This study demonstrated that comparing daytime with nighttime 24 hour ambulatory blood pressure, 20 of 24 patients (83%) with acute stroke with hypertension, did not show nocturnal blood pressure dip, and there was sustained high nocturnal blood pressure in patients with acute stroke with hypertension. 2)There were significant differences between 24 hour ambulatory mean daytime blood pressure and mean nighttime blood pressure in patients with acute stroke without hypertension, so was lower in nighttime (p<0.05). 3)It is likely that in acute stroke patients with hypertension, patients with higher blood pressure on admission had more abnormality of nocturnal blood pressure dip. CONCLUSION: These results suggest that in patients with acute stroke, 24 hour ABPM is useful method to assess diurnal variation and evaluate hypertension in acute stage of stroke patients, and suggest that patients with acute stroke with hypertension trend to loss of nocturnal blood pressure dip.

Primary syphilis affects the genital and, less frequently, the extragenital regions. Approximately two-thirds of extragenital chancres occur above the neck, and about one-half of these are seen on the lips, the perioral region, or in the oral cavity. We present a case of a 32-year-old woman with a 2-month history of discharging ulcers on both oral angles. She had a history of orogenital sexual contact. Serologic tests for syphilis was positive, particularly the VDRL (1:128), confirmed by TPHA. The biopsy specimen showed a predominant infiltration of plasma cells in the dermis. The skin lesions improved after 4 weeks treatment with doxycycline.

Clinical guidelines suggest that suspicious pigmented lesions of the plantar or palmar area require biopsy for early detection of acral melanoma. We present here a case of acral lentiginous melanoma in which various melanocytic atypia was observed at each biopsy site, including focal melanocytic proliferation. We suggest that this atypical melanosis is part of a contiguous phase of invasive tumor growth, which is known as the very early stage of melanoma in situ. In addition, noninvasive dermoscopy has been effective for the early discovery of hidden lesions of acral melanoma.
