The authors aimed to apply a nonsurgioal and atraumatic method for avulsing dystrophic nails due to onyohomyoosis by using 22.25% urea ointment under occlusive dressing. One hundred and eighty-nine nails with onychomycosis in fifty-five patients were treated by this rnethod. The results obtained a,re as follows: 1. Of a total of 82 fingernails and 107 toenails in 55 patients, all fingernails and 103 toenails showed an excellent response with easy removal of the diseased nails. 2. The duration tha.t the occluded urea ointment remained in place before sucessful avulsion was 6.7(range, 3 to 18) days for fingernails, and 9.1(range, 3 to 18) days for toenails with onychomycosis. 3. Of 4 nails of control group which were treated with white petrolatum, none showed the significant improvernent. 4. The problems during this treatment were; severe irritation with pain(l case), mild irzitation and/or itching(5 cases), and pin-point bleeding on curettage of nail bed (19 cases). It is suggested the urea treatment has many advantages and seemed to be ideal for patients with digital vascular insufficiency and increased susceptibility to infection.

We present a case of bullous congenital ichthyosiform erythroderma in a two year old female, in whom no hereditary background was found. The skin lesion was characterized clinically by blister formation with generalized erythematous hyperkeratosis which was especially prominent on the flexural surfaces of extremities and intertriginous areas. The histopathologic examination revealed marked hyperkeratosis, cavity changes of the malpighian cells with perinuclear vacuoles and markedly thickened granular layer containing many keratohyaline granules.

We report a case of calcinosis cutis following administration of 10% calcium gluconate, used for the treatment of a hypocalcemic seizure in a 5-week-old neonate. After administration of 10% calcium gluconate, subcutaneous induration developed at the infusion site. The histopathological findings taken from the dorsum of the left foot showed multiple foci of calcium deposits with infiltration of epitheloid histiocytes between collagen bundles and foreign body giant cells phagocyting calcific granules throughout the reticular dermis and subcutis.

A 61-year-old female had neurofibromas situated on the right side of upper trunk, shoulder and neck in the distribution of dermatomes C3 and C4(right), which developed 3 years ago. There were not cafe-au-lait spots, axillary frecklings, or Lisch nodule (iris pignented hamartoma). Biopsy specimen showed collagenous wavy fibrils among which spindle-shaped and round cells were embedded as seen in the typical neurofibroma. This case was considered to be a segmental form of von Recklinghausen's disease.

The study was undertaken to asses the changes in the size and densities of intracranial hematomas by analyzingthe sequential CT examination of 23 patients ar Soon Chun Hyang College Hospital from July '80 to Aug. '81. Theresuls were as follows; 1. The high densities of hematoma were the cause of hematoma, hematoma locaiton, age andsex of patients, and initial hematoma size. 3. The CT findings that indicate complete absorption of hematomas werenormalization of mass effect, not diappearence of hematoma densities. 4. In intracerebral hematoma, the highdensity of hematoma reduced it's density and mass effect about 4-6 weeks duration. 5. In subdural hematoma, about7 weeks after head trauma, the CT findings were normalized.

Purpose:
To evaluate whether vascular uptake on 18 F-fluorodeoxyglucose positron emission tomography/computed tomography ( 18F-FDG PET/CT) during the clinically inactive state of Takayasu arteritis (TAK) is associated with disease relapse.
Materials and Methods:
Patients with TAK who underwent 18F-FDG PET/CT during the clinically inactive state of the disease between 2006 and 2019 were included. Clinically inactive disease was defined as a status not fulfilling the National Institutes of Health (NIH) criteria for active disease in TAK. Relapse was defined as recurrence of clinically active disease after a clinically inactive period, requiring change in the treatment regimen. Vascular uptake on 18F-FDG PET/CT was assessed using target/background ratio (TBR), calculated as arterial maximum standardized uptake value (SUV)/mean SUV in venous blood pool. Multivariable Cox regression analysis was performed to identify factors associated with relapse.
Results:
A total of 33 patients with clinically inactive TAK were included. During a median observation period of 4.5 (0.9–8.1) years, relapse occurred in 9 (27.3%) patients at median 1.3 (0.7–6.9) years. Notably, TBR [1.5 (1.3–1.8) vs. 1.3 (1.1–1.4), p=0.044] was significantly higher in patients who relapsed than in those who did not. On multivariable Cox regression analysis, the presence of NIH criterion 2 [adjusted hazard ratio (HR): 7.044 (1.424–34.855), p=0.017] and TBR [adjusted HR: 11.533 (1.053–126.282), p=0.045] were significantly associated with an increased risk of relapse.
Conclusion
Vascular uptake on 18F-FDG PET/CT and the presence of NIH criterion 2 are associated with future relapse in patients with clinically inactive TAK.
