ABSTRACT
To improve the oral health status of Korean people, it is necessary to encourage proper oral hygiene management habits, such as toothbrushing, through appropriate health promotion techniques. Therefore, the purpose of this study was to evaluate the removal of plaque and tooth abrasion using ultra-soft (filament 0.11~0.12 mm) and soft toothbrushes for toothbrushing. The plaque removal was performed using a dentiform and Arti-spray, and the Patient Hygiene Performance (PHP) index was calculated as the sum total score divided by the total number of surfaces. In the abrasivity experiment, according to the number of brushings, a micro Vickers hardness tester was used, and a sample in the range of 280~380 Vickers hardness number was selected. The number of toothbrushing stroke were 1,800 (2 months), 5,400 (6 months), 10,800 (12 months), and 21,600 (24 months). The tooth abrasion was measured using a scanning electron microscope. Statistical analysis was performed using IBM SPSS Statistics 22.0 and a p-value < 0.05 was considered significant. According to the results, there was no statistically significant difference in the degree of plaque removal between ultra-soft and soft toothbrushes. The difference in tooth abrasion between before and after toothbrushing was found to be greater with the soft toothbrushes than with the ultra-soft toothbrushes. Therefore, the ultra-soft toothbrush not only lowers tooth damage by reducing tooth abrasion, but also shows a similar ability to remove plaque as soft toothbrushes.

An intramural hematoma is a rare, challenging cause of myocardial infarction generally seen in middle-aged females with no atherosclerotic risk factors. Intravascular ultrasound is useful in diagnosing and managing intramural hematomas. Here, we present anintramural hematoma presenting with ST-elevation myocardial infarction without definite intimal dissection in an elderly man who was diagnosed using intravascular ultrasound and managed accordingly.

BACKGROUND: Psoas abscess is a rare condition with vague clinical presentations, therefore misdiagnosis or delayed diagnosis is often made. We have reviewed the characteristics of the clinical presentation, microbiology, and treatment of 24 patients with psoas abscess. METHODS: The records of all patients treated with psoas abscess at Ajou University Hospital between March, 1996 and May, 2001 were retrospectively reviewed. RESULTS: A total of 24 cases of psoas abscess were reviewed: among these 17 cases were due to secondary cases and seven cases were diagnosed as primary psoas abscess. The right side was affected in 11 cases, the left side in nine, and both sides in four. Methicillin-susceptible Staphylococcus aureus was the most frequent (7/24 cases) pathogen, which were detected in cultures from five of seven patients with primary abscesses, whereas Mycobacterium tuberculosis (6/17 cases) and mixed enteric flora were detected in secondary abscesses. Three of the patients with primary psoas abscess expired from septic shock. The mortality rate was 12.5%. CONCLUSION: A psoas abscess should be considered when any patient presents with nonspecific abdominal pain, back pain and fever. This condition may be diagnosed promptly with computed tomography. Treatment involves use of appropriate antibiotics, as well as drainage of the abscess. Antibiotic coverage must include S. aureus and enteric bacteria. However, in endemic areas (such as Korea), tuberculous infection should be also considered.

The idiopathic hypereosinophilic syndrome (HES) is a disorder marked by the sustained overproduction of eosinophils. The disease is characterized by damage of multiple organ including heart, nerve system, skin and lung due to eosinophilic infiltration and the diagnosis is one of exclusion. Rheumatologic manifestations of HES are infrequent. In about 10~40% of rheumatoid arthritis (RA) patients, persistent eosinophilia is observed. That can be due to the RA itself and is often associated with active disease and extra-articular features. Sometimes, it is attributed to the drug therapy, especially gold and penicillamine. We would like to report a 37-year-old female patient with HES who developed seronegative RA 2 years later.

Oral or rectal sodium phosphate(NaP) preparation is commonly used for the colonic cleansing. Since the sole route of excretion of absorbed phosphate is renal, diminished renal function will limit the ability to excrete a sudden phosphate load. To date, about 20 adult cases of hyerphosphatemia associated with oral or rectal sodium phosphate solution have been reported, but not a single case in Korea to our knowledge. We report two cases of hyperphosphatemia and hypocalcemia after the administration of NaP(Colclean(R)) to reemphasizes the potential hazard of sodium phosphate bowel preparation in patients with compromised renal function.

A case of renal amyloidosis with crescentic glomerulonephritis associated with rheumatoid arthritis is described. A 60-year-old female with 15 years' history of rheumatoid arthritis developed nephrotic syndrome followed by rapid deterioration of renal function. Glomerular amyloid deposition and sclerotic change was present in kidney biopsy specimen and crescentic change was found in 85% of the glomerulus. Electron microscopic finding of glomerulus showed randomly oriented, rigid-appearing, long nonbranching fibrils. The patient was treated with intravenous high-dose methylprednisolone pulses combined with intravenous cyclophosphamide followed by oral corticosteroids. Three months after the above treatment, renal function gradually improved, reaching serum creatinine level to 2.5 mg/dL. But the nephrotic range proteinuria persisted.

Tuberculous splenic abscess is extremely rare in non- immunocompromised host. Although it has been increased since 1991, particularly in the HIV positive patients, it remains rare in the healthy patients. Only three cases have been reported in Korea. We report two cases of tuberculous splenic abscess presented as FUO in the previously healthy. One was improved by medical therapy and the other by splenectomy. It is important to include tuberculous splenic abscess in differential diagnosis of FUO, especially in case of splenic abscess that do not respond to empirical antibiotic therapy.
