Corrosion of orthodontic brackets in different spices:In vitro study.

Context: Moist environment in the mouth varies and causes variable amounts of corrosion of dental materials. This is of concern particularly when metallic implants, metallic fillings, orthodontic appliances are placed in the hostile electrolytic environment in the human mouth. Components of diet rich in salt and spices are important factors influencing the corrosion of metallic appliances placed in the oral cavity. Aims: To study in vitro corrosion of orthodontic metallic brackets immersed in solutions of salt and spices in artificial saliva. Materials and Methods: Orthodontic brackets were used for corrosion studies in artificial saliva, salt, and spices using electrochemical technique and surface analysis. Electrochemical studies using different parameters were done in solutions of artificial saliva containing salt and spices. Photomicrographs from the optical microscope were also obtained. Results: Results of corrosion studies have clearly demonstrated that certain spices such as turmeric and coriander are effective in reducing corrosion, whereas salt and red chili have been found to enhance it. Surface analysis of small pits present on the surface of the as-received bracket will initiate corrosion which leads to more pitting.

A Case of Eosinophilic Fasciitis Presenting as Pitting Edema of the Lower Extremities

Eosinophilic fasciitis is a rare disease characterized by diffuse fasciitis with peripheral eosinophilia and progressive induration and thickening of the skin and soft tissues. We report a 19-year-old female who presented with pitting edema in both lower extremities. She had a history of excessive physical activity before her symptoms developed. Physical examination revealed 2+ pitting edema in both lower legs. She complained of mild pain in both knee joints and feet, with no tenderness or heating sensations. Laboratory results were unremarkable except for severe eosinophilia. Parasite infection, venous thrombosis, and cardiac and renal problems were excluded. A magnetic resonance imaging study of both lower extremities revealed increased signal intensity in the subcutaneous lesions, consistent with superficial inflammation of the fascia. Mixed perivenular lymphoplasmacytic and eosinophilic infiltration in the subcutaneous lesion were observed on biopsy. The patient was treated with corticosteroids, resulting in remarkable improvement in both edema and eosinophilia.

Objective To analyze the clinical features and outcome of remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome,and enhance the understanding of it.Methods Fourteen cases of RS3PE syndrome treated in the Department of Rheumatology and Immunology were analyzed retrospec-tively,including the clinical characteristics,laboratory data.Data were presented as -x±s.Results Fourteen patients(nine man,five women) with RS3PE were enrolled.Their age was (68±9) (range:52-78)years.The main clinical features were acute onset symmetrical edema in both hands and feet and polyarthritis.Polyarthritis were involved in hand joints in 14 patients,wrists in 13 patients,knees in 10 patients,ankles in 9 patients,and shoulders in 8.In laboratory examinations,the average value of erythrocyte sedimentation rate was (68±26) mm/l h and C-reactive protein was (49±41) mg/L.Mild anemia of normocytic-normochromic type and mild low level of serum albumin were frequent findings.Antinuclear antibody was present only in one patient at low titer (1∶20).Rheumatoid factor and other auto antibodies were all negative in patients.Before corticosteroid treatment,the MRI test was performed in 8 patients and revealed prominent synovitis and articular effusion.Two cases had bone erosions on MRI; five patients were fuond to have malignant tumors,three of them initially presented with RS3PE.Polyarthritis and edema were relieved after treated with low dose corticosteroids and DMARDs drugs.But those patients with cancer were easily to recurr.Conclusion RS3PE syndrome is relatively uncommon.It occurs predominantly in elderly men and is characterized by rapid-onset symmetrical polyarthritis,presence of pitting edema of both hands and feet.Erosive changes can be seen on MRI.Patients usually have dramatic response to low dose corticosteroids and DMARDs drugs.Patients should be closely followed as RS3PE is closely related to cancer.

Effects of Seifu on Blood Pressure, Pain and Edema / 日本温泉気候物理医学会雑誌

<B>Introduction</B><BR>  Seifu, devised in 1992 by Xu, is a method of treatment through “pulling the skin”, unlike the approaches of treatment adopted in Shiatsu, massage, or acupuncture. This paper reports our recent evaluations of the effects of Seifu on the blood pressure, pain, and edema.<BR><B>Materials and Methods</B><BR>  The blood pressure was measured before and after Seifu in 36 individuals (mean age : 78.6±6.6 years) who underwent Seifu for 5 sessions or more. The effects on edema were evaluated in 14 individuals aged 45-90. Changes in the severity of edema following Seifu were analyzed. The effects on pain were evaluated in two ways.<BR>1) Effects on acute pain<BR>  The effects on pain arising from injection into the knee were evaluated in three groups of patients with osteoarthritis of the knee: Group A (injection after the application of Seifu to the acupuncture point Gohkoku (LI4); n=7, mean age: 72.8±2.8 years), Group B (injection after the application of Seifu to the area around the knee; n=198, mean age: 75.3±9.1 years) and Group C (injection after the application of Seifu to the acupuncture point Saninkoh (SP6) ; n=62, mean age: 75.0±7.5 years).<BR>2) Effects on subcuate and chronic pain<BR>  Pain was evaluated before and after Seifu using a visual analog scale (VAS) in 103 patients with some subacute or chronic pain(n=594, mean age: 73.4±12.4 years).<BR><B>Results</B><BR>1.

Nail Abnormalities in Alopecia Areata / 대한피부과학회지

BACKGROUND: Nail abnormalities may be associated with alopecia areata and nail abnormalities in alopecia areata are reported to range from 10%-66%. OBJECTIVES: This study investigates the clinical characteristics of nail abnormalities in alopecia areata, such as prevalence depending on sex, age and severities of hair loss. METHODS: Prospective analysis was undertaken by examining the finger nails of 424 alopecia areata patients and the nails of 465 non-alopecic patients were examined as controls. RESULTS: The number of the patients was 424(214 males, 210 females) and their mean age was 28.6 years (range 1-69). Nail abnormalities were noted in 98 (23.1%) out of 424 patients and in 24 (5.1%) out of 465 controls. According to age group, the prevalence of nail abnormalities was high at age under 9(31.7%) and at age of 10-19 (31.6%). The incidence according to severity of hair loss was 20.8% in below 50% of hair loss on scalp, 27.8% in 51%-100% of hair loss on scalp and 41.5% in 51%-100% of hair loss on the scalp and also involving body hair. The Frequent nail abnormalities were leukonychia punctata (8.5%) and pitting nail(8.0%). The other minor nail abnormalities were onychorrhexis, transverse ridging, trachyonychia, melanonychia, abnormality of lunula, onycholysis and koilonychia. CONCLUSIONS: The incidence of nail abnormalities in alopecia areata was significantly higher than in controls and the nail abnormalities were more common in children. The more severe was the degree of alopecia, the higher was the prevalence of nail abnormalities. Leukonychia punctata and pitting nail were frequently found in alopeica areata in Korea. The examination of nail in alopecia areata patients may be helpful in expectation of prognosis.

A Case of Remitting Seronegative Symmetrical Synovitis with Pitting Edema(RS3PE) Syndrome / 대한류마티스학회지

RS3PE is used to describe patients who have peripheral seronegative polyarthritis and pitting edema, especially in a man older than 60. It is characterized by sudden onset, high sedimentation rate, lack of bony erosion, remission within 18 months and good prognosis. Whether the RS3PE is a unique disease or syndrome has long been discussed, but conclusion was not obtained. We describe a 72 year old man of RS3PE with a review of the literature.

Pulmonary Diffusing Capacity in Patients with Liver Cirrhosis / 대한내과학회지

About a third of the patients with decompensated liver cirrhosis have reduced arterial oxygen saturation and are sometimes cyanosed in the absence of any apparent lung or heart disease; There is a reduction of diffusing capacity without a restrictive ventilatory defect. The aim of this study was to determine diffusing capacities in patients with chronic liver- diseases. The diffusing capacities and arterial oxygen saturations were measured in 25 patients with chronic active hepatitis(CAH), 9 early cirrhotics (early LC), 36 cirrhotics(Child's class A) and 11 cirrhotics(Child's class B). The anterior tibial area was observed for pitting edema, and Thallium-201 test per rectum(shunt index) was done. Hypoxemia was not observed in all subjects. The number of cases with decreased pulmonary diffusing capacity (DLco) is 3/25(12.0%) for CAH, 3/9(33.3%) for CAH with early liver cirrhosis(LC), 17/36(47.2%) for LC(Child's class A) and 6/11(54.5%) for LC(Child's class B). The mean+/-standard deviation of Dlco(% predicred) are 93.1+/-12.1 for CAH, 85.7+/-12.3 for CAH with early LC, 82.2+/-14.7 for LC(Child's class A) and 80.4+/-6.9 for LC(Child's class B), There is a significant difference between DLco in CAH and that in LC(Child's class A)(p0.3) had significantly lower DLco than these with lower shunt index(0.3) or pitting edema. This may be due to an increased systemic blood flow shunt and an increased generalized interstitial edema. Pulmonary function tests including diffusing capacity may be useful as prognostic parameters in patients with chronic liver disease, especially in those with CAH or early LC.
