Variety of pulmonary lesions are thought to be associated with rheumatoid arthritis (RA). These lesions traditionally have included pleurisy with or without effusion, Caplan's syndrome, pulmonary rheumatoid nodules, diffuse interstitial fibrosis, and pulmonary arteritis and hypertension. But little attention has been paid to the airways in RA. Recently, several reports have suggested an association between airflow limitation and RA, but its incidence is not known. Also whether there exists a parameter of disease activity of RA, suggesting the presence of small airway disease (SAD) is not clear. To answer these questions, the serologic parameters which reflect the disease activity of RA and pulmonary function tests which reflect small airway dysfunction were performed on 36 lifetime nonsmokers with RA who had normal chest x-ray findings. The prevalence of SAD and the relationships between the disease activity parameters of RA and pulmonary function were observed. The results were as follows. The percentages of patients with abnormal values for diffusing capacity, frequency dependence of compliance (C1.0/C0.0), forced expiratory flow 25-75%, Vmax50% and Vmax 75% were 45.5%, 62.5%, 40%, 22.8% and 11.4%, respectively. There was statistically significant negative correlation between C1.0/C0.0 and ESR. But consistent correlation between other pulmonary function tests and clinical and serologic parameters of RA, and differences in pulmonary function between patients who were serologically positive and negative for CRP and FANA, were not found. In conclusion, SAD, without the influence of smoking, is frequently associated with RA, but the presence of SAD cannot be predicted from any clinical and serologic parameters of RA currently in use.

Seventy cases of Takayasu arteritis in Korean children are reported. There were 57 females and 13 males (male-to-female ratio; 1:4.4). The youngest patient was a 3-year-old female. Family history was positive in one patient. The most common chief complaints on admission were dyspnea, headache, palpitation, and edema which were due to hypertension and congestive heart failure. Hypertension was seen in 65 out of 70 patients (92.8%). The abdominal aorta, thoracic aorta, and renal arteries were the most commonly involved sites in these children. Two patients had nephrotic syndrome. The frequency of positive tuberculin reaction was much higher in children with Takayasu arteritis compared with the general population, and the intensity of the reaction was also stronger. The majority of the patients required immediate medical treatment to control congestive heart failure due to hypertension at initial presentation. When ESR was elevated, corticosteroid was administered. Surgical treatment showed good results in six out of ten cases. Percutaneous intraluminal angioplasty was effective for lowering the blood pressure in six out of nine cases. In three cases, restenosis occurred and angioplasty was repeated in two cases.

With the advent of sonography and CT, renal cell carcinoma has increasingly been diagnosed in its early stage, with simple hematuria or no symptoms as the incidence of patients with masses and extrarenal extensions decreased. Correlating the clinical manifestations with stage, hematuria and pain may not imply an advanced lesion (31.4% Stage I). By adequate use of B ultrasonography and/or other instrument, many of renal cell carcinoma could be detected in its asymptomatic stage, a crucial requirement for better therapeutic results. The authors' data showed that fever, elevated ESR, varicocele and general malaise did imply advanced lesions or possible early metastasis after operation. On the other hand, complication with hypertension or erythremia could speak for an early lesion if diagnosis is made in time. Therefore, stratification of the extrarenal manifestations into endocrine and non-endocrine phases may help assess prognosis.

Plasma viscosity (Pv), and that of an erythrocyte suspension in isotonic saline solution (called erythrocyte viscosity--Ev) were determined by means of a viscosimeter of personal construction. The Ev/Pv ratio, called relative erythrocyte viscosity (Rv), was then calculated. The measurements were performed in flow conditions similar to the physiologic ones. An analysis of the variations of these parameters in different internal diseases has revealed high Pv values in the pathologic states associated with dysproteinemia. Pv correlates with the ESR but not with the hematocrit. Ev levels were increased in many diseases and did not correlate with any of the current laboratory parameters. Ev might be a prognostic factor for the arterial hypertension evolution. Rv analysis suggests a possible dynamic balance between Pv and Ev.

Renin-angiotensin-aldosterone++ system was investigated in 60 patients suffering from rheumatoid arthritis. Forty-four of them (group 1) had arterial hypertension (144 +/- 4/94 +/- 2 mm Hg), sixteen were free of hypertension (120 +/- 3/80 +/- 1 mm Hg). Twenty-nine control subjects comparable by AH standing and demographic parameters had essential hypertension stage IB-IIA by A. L. Myasnikov classification (141 +/- 3/89 +/- 1 mm Hg). A tendency to renin suppression was dominating in 72% of group 1 patients (plasma renin activity less than 1.0 ng/ml/h). In this group there appeared high concentrations of A II (14.2 +/- 3.1 pg/ml) and plasma aldosterone++ (238 +/- 94 ng/ml). Rheumatoid vasculitis manifested in 86% of patients. Control subjects exhibited plasma renin activity greater than 3.0 ng/ml/hin 48%, average A II concentration was similar to that of group 1 (12.4 +/- 2.7 ng/ml/h, p greater than 0.05), plasma aldosterone++ level was significantly lower (176 +/- 29 ng/ml, p less than 0.05). Correlations were established between A II concentration and ESR (r = 0.39, p less than 0.05), A II and rheumatoid factor titers (r = 0.40, p less than 0.05). These indicate that immunopathological reactions are responsible for shifts in renin-angiotensin-aldosteron system in hypertensive rheumatoid arthritis subjects.

The investigation of spontaneous hypertension by means of SL-technique is reported. Two component ESR spectra of hypertensive and normotensive rats are simulated. The conventional W/S ratio was shown not to be a measure of relative concentration of two label binding sites ("strongly" and "weakly" immobilized), but it represents alterations in line shapes.

Central nervous system is rarely involved in progressive systemic sclerosis (PSS) unless there are concomitant abnormalities in renal or lung function or hypertension. A 72-year-old woman with typical PSS developed cerebellar bleeding. Medical history records revealed, she had noted the onset of Raynaud's sign on her upper extremities at the age of 37. This was followed by necrosis and repeated infection, and as a result, shortening of her fingers in her 40's. The disease progressed and involved lower extremities, and then face and body in her 50's. Aortic valve stenosis was diagnosed at 69 year old, cardiac myopathy at 70 and at the age of 71 infectious dermatitis in both inguinal regions. Mild anemia, hypoalbuminemia and the decrease of serum Fe were discovered in June 1988. At the same time, prolonged ESR, positive C-reactive protein, RA, and anti-nuclear-antibody were also noticed. A chest roentgenogram revealed pulmonary fibrosis. Systemic hypertension was not noticed on the clinical course. She developed an onset of vertigo and vomiting in the morning of August 8, 1988. Consequently, she was brought to our hospital. She was alert but a physical examination showed a swallowing disturbance, dysarthria, right cerebellar ataxia, nystagmus and hypertension (192/100 mmHg). A CT examination on admission revealed a slightly low density area in right cerebellar hemisphere without mass effect. She was treated with dextran and mannitol and her condition improved on the 6th day of her admission. She was alert and blood pressure calm down to 120/70 mmHg without the use of anti-hypertension drugs on August 21.(ABSTRACT TRUNCATED AT 250 WORDS)

The patient was a 29-year-old woman. She was well until autumn 1983, when she presented with polyarthralgia, fever above 39 degrees C, hepatosplenomegaly, swelling of lymphnode and salmon pink rash. Laboratory tests revealed marked leucocytosis with shift to the left, elevated ESR, strong positivity of CRP and abnormal liver function tests. However, anti-nuclear antibody and RA factor were negative. She was diagnosed as adult onset Still's disease (AOSD) by characteristic clinical course and laboratory data. During her disease course these abnormal findings could be well controlled neither by nonsteroidal anti-inflammatory drugs, immunosuppressive agents nor corticosteroids. Two and half years after the first admission, she began to complain of dry cough, dyspnea on efforts. Auscultation revealed an increased pulmonic sound and systolic murmur of cardiac apex. Chest X-Rays showed enlarged main pulmonary arteries. The lung fields were normal. Pulmonary function tests gave no evidence of a significant obstructive or restrictive defect but showed the low DLco and hypoxemia. Ventilation-perfusion lung scanning failed to reveal pulmonary embolism. Finally, right heart catheterization confirmed the pulmonary precapillary hypertension. Her pulmonary hypertension has progressed rapidly, strongly suggesting poor prognosis. Her pulmonary hypertension associated with no apparent parenchymal involvement was thought to be caused by a pulmonary vascular change probably related to AOSD. This case is a first case of AOSD with pulmonary hypertension.

Three patients presented with a prolonged illness accompanied by fever, weight loss, high ESR, neutrophilia, abnormal liver function tests, urinary abnormalities and, in one case, splinter haemorrhages and impairment of renal function. Aortic dissection was diagnosed 3-12 weeks after the onset of the illness, and probably accounted for the entire syndrome. All abnormalities resolved spontaneously over the following months. There are few similar cases in the literature, and the syndrome could easily pass unrecognized. Aortic dissection should be considered as a possible cause of any systemic illness of sudden onset, but especially if there is an initial history of chest or abdominal pain, or evidence of previous hypertension or other risk factors.

A case of polyarteritis nodosa (PAN) in a 54 year-old man is presented. The clinical picture showed a 6-month history of mixed sensorimotor distal symmetrical polyneuropathy in all limbs together with anorexia, weight loss, fatigue, arthralgia, myalgia, mild fever and hypertension. The laboratory studies showed leucocytosis, elevated ESR, positive HBsAg and presence of cryoglobulins. Selective renal, celiac and mesenteric angiography was performed by femoral approach and has showed innumerable aneurysms most of them in hepatic and renal circulation. After about two weeks death has occurred. A brief discussion is done on clinical aspects of PAN pointing out the importance of HBsAg determination on etiopathogenesis and angiographic study on diagnosis.
