A 47-years-old woman presented with a 2-month history of a dry mouth and dry cough. The patient had been taking medication for Sj$\ddot{o}$gren's syndrome for approximately 7 years. The chest radiography showed multiple cystic lesions and a hazy density in both lower lung fields. The HRCT showed a diffuse ground glass like appearance and multiple variable sized cystic lesions in both lung fields. After medication, the symptoms were aggravated. Bronchoscopy was preformed with a transbronchial lung biopsy. The biopsies showed an infiltration of lymphocytes, neutrophils, monocytes and histiocytes through the interstitial space of the alveola and a widening of the alveolar septa. However, the histological findings of the cysts were not obtained. Sj$\ddot{o}$gren's syndrome is a slowly progressive inflammatory autoimmune disease, which is characterized by lymphocyte mediated destruction of the exocrine glands, with pulmonary involvement in approximately 19-65%, High-resolution CT is a sensitive technique for assessing the pulmonary involvement in patients with Sj$\ddot{o}$gren's syndrome. Although a lung biopsy is not always necessary for establishing a diagnosis of an interstitial lung disease in Sj$\ddot{o}$gren's syndrome. A lung biopsy may reveal a wide spectrum of changes ranging from a mild inflammatory response to end stage fibrosis with honeycombing. Because of the predominantly peribronchiolar inflammatory infiltration and inspissated secretions the cysts were suspected to have been formed by the ball-valve phenomen. However, no definite evidence was obtained.

Terbinafine, a fungicidal agent used for the treatment of onychomycosis, has been found to be safe and adverse effects are usually mild and transient. Neutropenia is a rare side effect of terbinafine. Terbinafine-induced neutropenia have been reported 7 cases worldwide and these patients had no predisposing factors that give rise to developing neutropenia. To date there has not been reported in Korea. We report a case of systemic lupus erythematosus of 47-year-old female patient who developed deep neck infection requiring intravenous antibiotics, tracheostomy, granulocyte colony-stimulating factor(G-CSF) to recover from terbinafine-induced neutropenia.

Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

Purpose : Diabetic nephropathy is a serious complication of diabetes and accounts for much of its morbidity and mortality. It is well known that the overt clinical phase of diabetic nephropathy is preceded for many years by the presence of microalbuminuria. Microalbuminuria is thought to be a marker of widespread vascular damage and may underlie the propensity toward severe extrarenal vascular disease in microalbuminuric patients. Metalloproteinase-9 has a broad substrate specificity for native collagens as well as proteoglycan and elastin. One study reported that an increased plasma metalloproteinase-9 concentration precedes the development of microalbuminuria in type 2 diabetic patients. Another study reported that a high glucose concentration cause a abnormality on the activity of metalloproteinase by the mesangeal cell. The purpose of the present study was to examine whether palsma metalloproteinase-9 concentrations are altered at various complications in type 2 diabetic patients. Methods : Sixty patients with type 2 diabetes and thirty healthy control were recruited for the present study. No patient had any malignancy or history of heart disease, liver disease, collagen disease. We recorded age, duration of diabetes, and blood pressure. After an overnight fast, blood was drawn from an antecubita1 vein of measurement of glucose, metalloproteinase-9, HbA1C, and serum creatinine. To measure plasma concentration of metalloproteinase-9, a one step sandwich enzyme immunoassay using two monoclonal antibodies was used. Patients were divided into two group according to the presence or abscence of microalbuminuria. The groups were then compared with regard to clinical and laboratory characteristics and serum concentration of metalloproteinase-9. Results : The mean serum levels of metalloproteinase-9 in diabetic patients (62.32±25.83ng/㎖) were significantly higher than in healthy controls(12.92±4.97ng/㎖) (p<01). The mean serum levels of metalloproteinase-9 in diabetic patients with microalbuminuria(81.16±41.43ng/㎖) were significantly higher than in those with normoalbuminuria(31.48±7.34ng/㎖) (p<01) and much more than in healthy control(12.92±4.97ng/㎖) (p<05). Furthermore, the severity of nephropathy were closely associated with the serum metalloproteinase-9 level and the serum metalloproteinase-9 level was significantly correlated with microalbuminuria. The mean serum level of metalloproteinase-9 in diabetic patients with retinopathy(61.74±39.07ng/㎖) was significantly higher than in those with no retinopathy(34.98±9.02ng/㎖) (p<05). But, in diabetic patients with normoalbuminuria, there is no difference between the groups with retinopathy versus no retinopathy. Conclusion : In summary, a sustained increase in serum metalloproteinase-9 in patients with type 2 diabetes is associated with a high risk for the development of microalbuminuria. The results of this study suggest that the serum rnetalloproteinase-9 was a useful and noninvasive marker for the development of diabetic nephropathy. It could be also used to predict the development of diabetic complications and to assess therapeutics or the prognosis of diabetes. The usefulness of this model will be clarified by a larger scale and serial study.
