Tremor is defined as involuntary, rhythmic, and sinusoidal movement. The rate, location, amplitude, and constancy vary depending on the specific type of tremor and its severity. Etiologies and treatment of tremors differ according to the type of tremor. It is helpful to determine whether the tremor is present at rest, with posture-holding, with action or with intention maneuvers. Rest tremor is most typically present in patients with Parkinson's disease. Physiologic tremors and essential tremors are common forms of postural tremor. Intention tremor is typically present in cerebellar lesions. Associated neurological symptoms and signs are also helpful for differential diagnosis. Not all patients with hand tremor have Parkinson's disease. Rest tremor, bradykinesia, rigidity, and loss of postural reflex are cardinal signs of Parkinson's disease. Careful observation of the patient is the key point of diagnosis in patients with tremor.

BACKGROUND AND OBJECTIVES: There has been much need for standard normal values of echocardiographic indices in Korea. Echocardiography Council of the Korean Society of Circulation performed multicenter trial for estimation of normal values of echocardiographic indices. METHOD: In 19 university or general hospitals, echocardiographic specialists measured frequently used echocardiographic indices with the same method in healthy people. The measured indices were 36 items which involved M-mode, 2-dimensional and Doppler echocardiographic parameters. All the results were recorded on video tapes and reviewed by the review committee. The results were included for analysis only if the review committee accepted them. RESULTS: Total 371 healthy people were included. There were 189 women. Their age ranged from 3rd decades to 8th decades. Complete measurement of all the indices was done in 225 people. Left ventricular wall thickness, aorta size, left atrial size and left ventricular mass in M-mode echocardiographic measurement changed significantly with the increase of age(p<0.005). In 2-dimensional echocardiographic examination, sinotubular junction diameter of the aorta, anteroposterior & superoinferior diameters of left atrium, both ventricular outflow tract diameter and main pulmonary artery diameter changed with the increase of age(p<0.01). Diastolic dysfunction became prominent with the increase of age in Doppler examination. CONCLUSION: We conclude that these data could be used as the standard criteria for echocardiographic examination in Korea. However, age factor should be considered when they are applied because many echocardiographic indices change significantly with the increase of age.

Tension-type headache is now the term used to describe headaches that have previously been grouped under various ill-defined headings, such as 'tension headache', 'stress headache' and 'muscle contraction headache'. Tension-type headaches are characterized by a pain that is mild to moderate in severity, bilateral in distribution, pressing or tightening in quality, and are not accompanied by major systemic disturbances or neurological signs. Tension-type headaches, the most prevalent from of headaches, are differentiated as being either episodic or chronic, Very little research on this disease has actually been carried out, and knowledge about key pathophysiological issues, such as the nature and site of the noxious stimulus, is limited. As a result of this and the lack of scientific interest for this from of headache in the medical field, the treatment is non-specific. However, it is suggested that a peripheral mechanism of tension-type headache be involved in the episodic form, whereas a secondary central sensitization and/or an impaired supraspinal modulation of incoming stimuli be involved in subjects with the chronic from. While most people with tension-type headaches experience mild, infrequent episodes, so that they do not regard the headache as a disease, a monority have chronic and often daily symptoms. The understanding of the balance between peripheral and central components in tension-type headache may lead us to a better prevention and treatment of this most prevalent type of headaches. This article presents a review on the drug therapy of tension-type headaches in adults.
