OBJECT: Pre-ALL is a very rare preteukemic state, which percedes acute lymphocytic leukemia, while MDS(pre-ANLL), usually the well-known type of preleukemic state, precedes acute non-lymphocytic leukemia. Initially it shows transient pancytopenia without any evidence of leukemia in bone marrow findings, followed by acute lymphocytic leukemia after recovery from pancytopenia of a short period within weeks or months. We report a case with pre-ALL in childhood. CASE: A 15-month-old male baby was admitted with the complaints of fever and cough for 5 days and pallor for 2 weeks prior to admission. On admission, CBC showed pancytopenia without any evidence of leukemia, which was recovered spontaneously in a short period, and then was followed by acute lymphocytic leukemia of CALLA negative, early pre-B cell type. During antileukemic chemotherapy, he had suffered from severe bacterial infections and was finally died of sepsis 8 months after first admission. CONCLUSION: We report a case of pre-ALL in childhood, which was preceded by CALLA negative, early pre-B cell ALL, with a review of the literatures, briefly.

2.Severe Upper and Lower Tarsal Ectropion with Immunoglobulin G4-related Ophthalmic Disease
Journal of the Korean Ophthalmological Society 2020;61(8):944-949
Purpose:
To present the first case of severe upper and lower tarsal ectropion associated with immunoglobulin G4 (IgG4)-relatedophthalmic disease.Case summary: A 37-year-old male presented with relapsed eyelid swelling and periocular inflammation in the left eye for7 years. He had severe upper and lower tarsal ectropion and a thickened upper eyelid with prolapsed conjunctival fornix. Orbitalcomputed tomography showed a poorly defined anterior orbital mass involving the lacrimal gland and upper and lower eyelids onthe left eye. The severe upper and lower eyelid ectropion was corrected by a modified spindle procedure and lateral tarsal strip.Hard, ill-defined fibrotic tissue and a mass around the lateral upper tarsal plate were discovered that required excision of themass and a biopsy. Hematologic and histopathologic findings of the orbital mass indicated IgG4-related ophthalmic disease withsevere upper and lower ectropion caused by the disease.
Conclusions
In cases of severe upper and lower eyelid ectropion caused by chronic inflammation, as seen in this case, not onlyeyelid tightening with excision of the causative mass but also a modified spindle procedure is required to prevent rotation of theeyelid.

Neuroendocrine tumor (NET) of the colon and rectum has been reported to have a low incidence and aggressive progression; it is frequently misdiagnosed and its treatment is not well documented. Four NET cases were collected at our hospital during the previous year of a colon cancer survey. Endoscopic mucosal biopsy of the colon was done for each case and all the cases proved to be adenocarcinomas. Curative surgery was conducted after the preoperative diagnostic and staging evaluation was completed. The locations of the primary lesions of the patients were all different; cecum, ascending colon, splenic flexure colon and sigmoid colon. The disease was advanced in all cases and the first postoperative diagnosis was poorly differentiated adenocarcinoma. Immunohistochemical tests followed and all the cases were positive for chromogranin A staining. A retrospective study was then conducted.

OBJECTIVE:The purpose of this study is to evaluate the CT findings of the carcinoma of the ampulla of Vater and to differentiate from other periampullary carcinoma including the carcinoma of the distal common bile duct and pancreas head. MATERIALS AND METHODS: We retrospectively reviewed the CT findings of 13 cases of the carcinoma of the ampulla of Vater, 20 cases of the carcinoma of the distal common bile duct and 20 cases of the carcinoma of the pancreas head confirmed by pathology. Five millimeter consecutive settings of CT scan were performed in all cases on ampulla level with supine position. The CT findings were retrospectively evaluated in view of common bile duct dilatation, pattern of termination of bile duct, pancreatic duct dilatation, protruding mass in duodenal lumen, and regional lymph node metastasis. RESULTS: All case of the carcinoma of the ampulla of Vater(13/13) and distal common bile duct(20/20) showed common bile duct dilatation with abrupt termination. Among the 10 cases of the carcinoma of the pancreas head with common bile duct dilatation, five cases each had is abrupt termination(5/20) and gradual stenosis of bile duct(5/20). Five cases of the carcinoma of the ampulla of Vater(5/13) and four cases of the carcinoma of distal common bile duct(4/20) showed pancreatic duct dilatation and all cases of the carcinoma of pancreas head show pancreatic duct dialtation(20/20). Twenty cases of the carcinoma of the ampulla of Vater showed protruding mass in the medial wall of the second portion of the duodenum(12/13) but only one case of the carcinoma of the distal common bile duct(I/20) and five cases of the carcinoma of the pancreas head (5/20) had protruding mass in the duodenal lumen. Only one case of the carcinoma of the ampulla of Vater showed(1/13) regional lymph node metastasis but three cases of the carcinoma of the distal common bile duct(3/20) and 18 cases of the carcinoma of the pancreas head(18/20) showed regional lymph node metastasis. CONCLUSION: Common bile duct dilatation with abrupt termination, protruding mass in the duodenal lumen and rare lymph node metastasis in CT may suggest the carcinoma of the ampulla of Vater.

Journal of the Korean Pediatric Society 1996;39(6):822-828
PURPOSE: Osteoporosis and growth failure have been known one of the serious side effects of corticosteroid therapy especially in children. This study was designed to evaluate the effect of long-term administration of steroids on bone mineral density(BMD) in children with nephrotic syndrome and its relationship to cumulative steroid dose, the duration of therapy and sex. Meathods : The BMD of the spine and arm were measured by dual energy x-ray absorptiometry in 24 children with biopsy-proven minimal change nephrotic syndrome who have been revealed steroid dependent and/or frequent relapse in its clinical course and in age- and sex-matched healthy controls. The mean duration of steroid therapy was 37+/-29.8 months and the mean cumulative steroid doses was 12.8+/-7.7g/m2. RESULTS: 1) The BMD at arm was 0.57+/-0.06g/cm2 in patient group and 0.59+/- 0.06g/cm2 in control group. The BMD at spine was 0.68+/-0.1g/cm2 in patient group and 0.76+/-0.1g/ cm2 in control group. Compared with control group significant decrease in BMD was detected in patient group at arm(p=0.011) and spine(p<0.01). The bone loss at spine and arm was -10.6+/-7.44% and -3.7+/-5.5%, respectively. The bone loss was more prominant at spine(p<0.01). 2) Bone loss at arm was significantly correlated to the total cumulative dose of steroid(Y=-0.0029-0.294X, r=-0.4148, p=0.0434), but was not correlated to the duration of steroid(Y=-2.15-0.04X, r=0.1396, p=0.4619). At spine, there were no significant correlation between bone loss and the cumulative steroid doses(Y=-8.47-0.178X, r=-0.19397, p=0.363) and the duration of steroid therapy (Y=-9.75-0.025X, r=0.09081, p=0.6332). CONCLUSIONS: The long-term use of steroid can induce significant bone loss at the both site of arm and spine. To minimize the extent of corticosteroid-induced bone loss, BMD measurement using dual energy x-ray absorptiometry in children with nephrotic syndrome would be helpful.

The authors retrospectively reviewed the high resolution computed tomographic scans of 19 patients who had hematogenous or lymphangitic metastatic lung lesions. In all patients, the histologic diagnosis for primary cancers and the radiographic manifestations of pulmonary metastasis were established. Certain characteristic findings of metastatic lung tumors on HRCT scans were evident: uneven thickening of bronchovascular bundles, multiple small nodules, thickening of interlobular septum, and the presence of polygonal lines. The nodules are more predominent in hematogenous metastasis. The prevalent site of nodules is cortical portion of lung.

PURPOSE: This study was performed to show the several clinical variables before and after the surgery that need to be considered for patient selection and whether there is an increased possibility of recurrence after surgery and whether this possibility can be reduced when adjuvant treatment is applied. METHODS: The outcome of SSM with immediate breast reconstruction, using follow-up data of cases performed at Asan Medical Center between September, 1996 and December, 2002, were retrospectively assessed and pathologically advanced breast cancer patients (stage III) were analyzed separately. RESULTS: 191 patients had undergone SSM with immediate reconstruction during the study period. The percentage of cases stage III was 15.2% (29 cases). Among these patients, 6 (20.7%) were suspected of being in the early stages of breast cancer prior to the surgery. The mean age of the advanced breast cancer patients was 37 years. Immediate breast reconstruction consisted of a pedicled TRAM flap (n=24), a insertion of tissue expander (n=4) or direct implant (n=1). Radiotherapy was performed in 16 patients (53.3%) and chemotherapy was conducted without delay in all case. With a median length of follow-up of 36.1 months for 22 patients, who under went the operation until December, 2001, local recurrence was 4.5% (1/22) with successful local treatment, and distant metastasis was 13.7% (3/22). There was no difference in the disease free survival compared to that of the non-reconstruction group (P=0.093). CONCLUSION: SSM with immediate reconstruction seems safe and effective for patients with advanced breast cancer. However an accurate preoperative assessment of the extent of the disease and discussion for the planning of treatment between surgeon and patient is required.

OBJECTIVES: The aim of this study is to evaluate the effect of light intensity variation on the polymerization rate of composite resin using IB system (the experimental equipment designed by Dr. IB Lee) by which real-time volumetric change of composite can be measured. METHODS: Three commercial composite resins [Z100(Z1), AeliteFil(AF), SureFil(SF)] were photopolymerized with Variable Intensity Polymerizer unit (Bisco, U.S.A.) under the variable light intensity (75/150/225/300/375/450mW2) during 20 sec. Polymerization shrinkage of samples was detected continuously by IB system during 110 sec and the rate of polymerization shrinkage was obtained by its shrinkage data. Peak time(P.T.) showing the maximum rate of polymerization shrinkage was used to compare the polymerization rate. RESULTS: Peak time decreased with increasing light intensity(p<0.05). Maximum rate of polymerization shrinkage increased with increasing light intensity(p<0.05). Statistical analysis revealed a significant positive correlation between peak time and inverse square root of the light intensity (AF:R=0.965, Z1:R=0.974, SF:R=0.927). Statistical analysis revealed a significant negative correlation between the maximum rate of polymerization shrinkage and peak time(AF:R=-0.933, Z1:R=-0.892, SF:R=-0.883), and a significant positive correlation between the maximum rate of polymerization shrinkage and square root of the light intensity (AF:R=0.988, Z1:R=0.974, SF:R=0.946). DISCUSSION AND CONCLUSIONS: The polymerization rate of composite resins used in this study was proportional to the square root of light intensity. Maximum rate of polymerization shrinkage as well as peak time can be used to compare the polymerization rate. Real-time volume method using IB system can be a simple, alternative method to obtain the polymerization rate of composite resins.

To evaluate MR findings of soft tissue masses in extremities and to find the helpful findings of distinguish benignity from malignancy, 28 soft tissue masses (22 benign and 6 malignant) in extremities were reviewed. T1-weighted, proton density, T2-weighted and Gd-DTPA enhanced images were obtained. MR images allowed a specific diagnosis in a large number of benign masses, such as hemangioma(8/9), lipoma(2/2), angiolipoma(1/1), epidermoid cyst(2/2), myositis ossificans(1/1), synovial chondromatosis(1/1) and pigmented villonodular synovitis (1/2). Specific diagnosis was difficult in the rest of the masses including malignancy. However, inhomogenous signal intensities with necrosis and inhomogenous enhancement may suggest malignant masses.
