BACKGROUND AND PURPOSE PCMR is used to evaluate the Chiari I malformation. We compared quantitative PCMR in symptomatic and asymptomatic patients with Chiari I. MATERIALS AND METHODS PCMR image data in an axial section near the foramen magnum in a consecutive series of patients with Chiari I malformations were evaluated. Patients were classified as symptomatic for a Chiari I if they had apnea...

Giardia lamblia cysts obtained from human symptomatic and asymptomatic donors were excysted in vitro. Excystation averaged 87% for cysts from symptomatic donors and 70% for cysts from asymptomatic donors.

OBJECTIVE To measure condylar displacement between centric relation (CR) and maximum intercuspation (MIC) in symptomatic and asymptomatic subjects. MATERIALS AND METHODS The sample comprised 70 non-deprogrammed individuals, divided equally into two groups, one symptomatic and the other asymptomatic, grouped according to the research diagnostic criteria for temporomandibular disorders (RDC/TMD...

BACKGROUND The purpose was to investigate prevalence of bilateral discoid lateral menisci (DLM) in Han Chinese patients who received surgery for symptomatic DLM, as well as a follow-up study of their asymptomatic contralateral knees using magnetic resonance imaging (MRI). METHODS A total of 110 patients [50 males and 60 females; average age: 21.95 ± 12.77 years (range: 6 to 67 years)] admitte...

Background and Objective: Asymptomatic bacteriuria is bacteria in the properly collected urine of a patient, leading to a urinary tract infection with no symptoms. Asymptomatic bacteriuria is a common complication in clinical practice with an increasing prevalence due to increase of age. The present study investigated the prevalence of asymptomatic bacteriuria among pregnant women receiving ant...

BACKGROUND Asymptomatic, or "silent" atrial fibrillation could increase the risk of stroke. Little is known about the frequency of asymptomatic atrial fibrillation in patients who also have symptomatic atrial fibrillation; similarly, little is known about the effect of antiarrhythmic drug therapy on asymptomatic atrial fibrillation. METHODS AND RESULTS Patients in sinus rhythm with a history ...

Case Description- Two female domestic short-hair cats Clinical Findings- The cats with clinical signs of regurgitation, dysphagia and respiratory distress were presented. Symptomatic sliding hiatal hernia was diagnosed by radiography in these cats. Treatment and Outcome- The hernias were corrected surgically by only left-sided fundic gastropexy in one, and by reduction of hiatal opening and g...

In this paper, we introduce a malaria model with an asymptomatic class in human population and exposed classes in both human and vector populations. The model assumes that asymptomatic individuals can get re-infected and move to the symptomatic class. In the case of an incomplete treatment, symptomatic individuals move to the asymptomatic class. If successfully treated, the symptomatic individu...

BACKGROUND AND STUDY AIMS  Endoscopic removal of asymptomatic common bile duct stones (CBDS) is generally recommended. Although many reports have described the risk of complications in endoscopic retrograde cholangiopancreatography (ERCP), no studies have addressed this problem in the context of asymptomatic CBDS. This study examines the risk of complications arising in ERCP for asymptomatic CB...

Ischemic pain threshold and tolerance levels using the tourniquet pain technique and electrical cutaneous pain thresholds were measured in patients with asymptomatic ischemic heart disease. Thirty asymptomatic patients, who repeatedly exhibited no angina pectoris pain during the occurrence of exercise-induced coronary ischemia (greater than or equal to 0.1 mV ST segment depression in exercise E...
