Pheochromocytoma is a rare, but an important cause of surgically curable hypertension. Pheochromocytoma is a highly vascular tumor and not infrequently undergoes hemorrhagic necrosis and pseudocyst formation. Such cystic pheochromocytoma may be accompanied by shock and sepsis and commonly invade adjacent organs, in which cases its diagnosis and management may be difficult. Herein we present a case of adrenal cystic pheochromocytoma which was accompanied by sepsis and hypertension and mimicked pararenal abscess with a review of literatures.

Left ventricular(LV) diastolic filling is abnormal at rest in many patients with coronary arery disease, even in the presence of normal resting LV systolic function. To determine the effects of improved myocardial perfusion on impaired LV diastolic filling and to detect the most sensitive parameter to assess LV diastolic function, gated radionuclide ventriculography were performed in 14 patients with coronary artery disease before and after successful percutaneous transluminal coronary angioplasty(PTCA). All patients had no previous myocardial infarction and no abnormal wall motion in gated radionuclide and contrast ventriculography. The following results were obtained; 1) There were no significant differences in the parameters of LV systolic function, such as peak ejection rate(PER, time to peak ejection rate(TPER), ejection fraction(EF) after successful PTCA. 2) Peak filling rate(PFR) and time to peak filling rate(TPFR), indexes of LV diastolic function, had no significant changes after successful PTCA. 3) The percent contribution of late diastolic filling to stroke volume(%LDF/SV) decreased from 26.5+/-6.8% to 19.1+/-6.6%(p<0.005 by paired t-test). These data suggest that in many patients with angina and normal LV systolic function, impaired global diastolic filling is a reversible manifestation of impaired coronary flow, and percent contribution of late diastolic filling to stroke volume(%LDF/SV) can be a sensitive parameter to evaluate impaired LV diastolic filling in coronary artery disease.

A 46-year-old woman was admitted with an ulcerative lesion on the posterior neck. Four months before admission, the patient took part in a faith healing ritual, which the pastor performed with his fingernails causing wounds. This abnormal method of healing caused repeated injury to the patient in the posterior neck area. Treatment with cefazolin was begun, but the lesion did not improve. Biopsy of the skin lesion and cervical lymph nodes was performed. Microscopical examination revealed findings highly suggestive of syphilis. Serological tests for syphilis were positive and a computed tomographic (CT) scan of the neck showed enlargement of regional lymph nodes and tonsils. A single dose of penicillin G 2.4 million units was given intramuscularly. Two weeks later, the wound had healed. Eight weeks after treatment, the Venereal Disease Research Laboratory titer had decreased and a CT scan of the neck showed a decrease in the size of the lymph nodes. We reasoned that syphilis was non-sexually transmitted, and that the healing ritual was the cause. Our case suggests that skin trauma by scratching with the fingernails may cause an accidental direct inoculation of Treponema pallidum, resulting in extragenital primary syphilis.

BACKGROUND: In the acute phase of myocardial infarction, the hemostatic mechanism is known to be activated. However, it remains unclear whether increased activity of the hemostatic mechanism is only a marker of the acute thrombotic episode or precedes its appearance. It is also inapparent whether a hypercoagulable state persist for a prolonged period after the apparent resolution of these disorders. METHODS: In a group of 23 patients with acute myocardial infarction who received fibrinolytic therapy with urokinase(group A) or tPA(group B), the plasma level of fibrinogen, antithrombin compared to those of the 10 normal controls. RESULTS: The plasme level of fibrinogen was significantly decreased in both group A and B before and 4 to 24 hours after thrombolytic therapy compared to that of normal controls. But it was increased 7 to 14 days after thrombolytic therapy. In a few of the patients, the plasma level of FDP and D-dimer were positive before thrombolytic therapy and in the most patients they were positive 4 hours after thrombolytic therapy. The plasma level of AT-III was significantly increased in both group A and B before thrombolytic therapy compared with that of normal controls, but, after thrombolytic therapy, there was no significant change in its level. CONCLUSIONS: In the patients with acute myocardial infarction, the thrombolysis occurred before thrombolytic therapy and it lasted for 24 hours after thrombolytic therapy.

BACKGROUND: Percutaneous mitral commissurotomy(PMC) has been known as an effective therapeutic modality for moderate to severe mitral stenosis. However, long-term results and factors influencing late outcome after PMC remain to be elucidated. MATERIALS AND METHODS: Three hundred and forty-six patients received PMC at Seoul National University Hospital between August, 1988 and March, 1996. We evaluated long-term results of these patients and assessed demographic, clinical, echocardiographic and hemodynamic variables in order to identify predictors of immediate and late outcomes. RESULTS: PMC was completed without major complication or technical failure in 339(98%) out of 346 cases. A good immediate result was obtained in 67% of cases. Multivariate study identified echocardiographic score(P=0.004) and left atrial volume(P=0.009) as independent predictors of immediate outcome. The estimated 3-year and 5-year event-free survival rates were 95.8+/-2.5% and 90.6+/-4.3%, respectively. According to multivariate analysis, the independent predictors of late outcome were pre-PMC left atrial volume(P=0.03), post-PMC mitral valve area(P=0.01), and severity of mitral regurgitation after PMC(P=0.03). CONCLUSION: Percutaneous mitral commissurotomy as a treatment for patients with mitral stenosis is safe, and achives good long-term results. Pre-procedural echocardiographic score, left atrial volume, post-procedural mitral valve area, and severity of mitral regurgitation affect the immediate and late outcomes after PMC.

Benign intestinal tumors are rare in infancy, however the authors describe an inflammatory myofibroblastic tumor (IMT) of the mesentery in a 3-month-old infant who was diagnosed incidentally. During operation, huge mass which was attached to proximal jejunum was resected, from which a histological diagnosis of IMT was made. A review of the literature for this rare condition was done to delineate the natural history of this tumor. Because of the risk of local recurrence and malignant transformation, IMT cases needed a long-term follow up.

Background: On March 22, 2020, intense social distancing (SD) was implemented in Korea to prevent the spread of coronavirus disease 19 (COVID-19). This study examined the impact of SD on diabetes control in older adults with diabetes. Methods: Adults aged 60 to 90 years with type 2 diabetes mellitus who were physically and mentally independent were recruited. Participants who had complete blood chemistry data from April to July 2019 (pre-SD era) and April to July 2020 (SD era) were enrolled. Data were obtained about physical activity, nutrition, sarcopenia, and psychological and mental health from questionnaires in April to July 2020. Calf circumference was measured. Results: In total, 246 people (100 men, 146 women; mean age, 73.8±5.7 years) participated in this study. The levels of glycated hemoglobin (HbA1c, 7.4%±1.0% vs. 7.1%±0.8%, P<0.001), fasting glucose (142.2±16.7 mg/dL vs. 132.0±27.7 mg/dL, P<0.001), and body weight (62.6±9.4 kg vs. 61.8±10.1 kg, P<0.01) were higher in the SD era than in the pre-SD era. Total physical activity was lower in the SD era (2,584.6±2,624.1 MET-min/week–1 vs. 1,987.3±2,295.0 MET-min/week–1, P<0.001). A larger increase in HbA1c level was associated with increased body weight and decreased physical activity. Conclusion SD had negative effects on diabetes management in older adults with diabetes. Fasting glucose and HbA1c levels and body weight increased during the SD era. Participants with reduced physical activity gained more weight and had higher blood glucose levels. Given that the COVID-19 pandemic is ongoing, health professionals and diabetes educators should monitor changes in lifestyle factors in older adults with diabetes.
