Neonatal diabetes mellitus (NDM) is a rare disease that occurs at less than 6 months of age and is presumably caused by a mutation in the gene that affects pancreatic beta-cell function. Approximately 80% of NDM cases reveal a known genetic mutation, and mutations in potassium inwardly rectifying channel subfamily J member 11 (KCNJ11) and ABCC8 affecting the pancreatic beta-cell adenosine triphosphate-sensitive potassium channel may be treated with oral sulfonylurea. Early recognition of mutations in KCNJ11 and ABCC8 is important because early administration of sulfonylurea can not only control blood glucose levels but also improve neurodevelopmental outcomes. In the present study, we report a case of NDM that initially presented as diabetic ketoacidosis at the age of 1 month, accompanied by seizures during hospitalization. After confirmation of the KCNJ11 gene mutation (c.989A>C), we started administering oral sulfonylurea (glimepiride) at the age of 2 months. After gradually increasing the dosage of glimepiride, insulin was discontinued at the age of 3 months. To date, the infant’s blood glucose levels have been well controlled without significant hypoglycemic events. No further episodes of seizures have occurred, and his developmental status is favorable.

BACKGROUND: The long-term prognosis of BK virus-associated nephropathy (BKVAN) in kidney transplant recipients (KTRs) is uncertain. We evaluated the long-term prognosis in KTRs with BKVAN and the clinical significance of BKVAN on post-transplant clinical outcome. METHODS: We retrospectively analyzed the medical records of 582 patients who underwent kidney transplant (KT) between 2001 and 2014. We divided the patients into a BKVAN group (15 patients) diagnosed by allograft biopsy and a control group (356 patients). RESULTS: The incidence of BKVAN was 4.0%, and the mean follow-up duration was 93.1 ± 52.3 months. Median time from KT to BKVAN diagnosis was 5.9 months (interquartile range [IQR], 4.4–8.7). In the BKVAN group, 9 (60.0%) KTRs with combined acute rejection progressed to graft failure, and the median time from BKVAN diagnosis to graft failure was 36.2 months (IQR, 9.7–65.5). Death-censored graft survival rate and patient survival rate in the BKVAN group were significantly lower than those in the control group. BKVAN and rejection were independent risk factors for graft failure. In the subgroup analysis, death-censored graft survival rate of KTRs with BKVAN with acute rejection was significantly worst in comparison with similar patients without BKVAN regardless of acute rejection (P < 0.001). CONCLUSION: The long-term prognosis of BKVAN with acute rejection was very poor because of graft failure caused by inadequate treatment for acute rejection considering BKVAN. Therefore, we should carefully monitor the allograft status of KTRs through regular surveillance tests after treatment for BKVAN with acute rejection.

Among total 108 cases of biopsy-proven fibroadenomas of the breast, which obtained from the files of the Asan Medical Center during one year period from October 1998 to September 1999, 23 cases cytologically diagnosed as high risk group were reviewed to retrieve the mis-leading factors. Initial cytologic diagnoses of 23 cases were proliferative breast lesion with atypia(high risk) in 21 cases(91.3%) and papillary neoplasm in 2 cases(8.7%). When we reanalysed 23 cases by Masood scoring system, they were classified as one non-proliferative breast lesion(4.3%), 16 proliferative breast lesions without atypia (69.6%), and 6 proliferative breast lesions with atypia(26.1%). None were subject to the category of carcinoma. Cytologic features leading to the overdiagnosis of high grade epithelial lesions were as follows; cellular dissociation without nuclear atypia, nuclear pleomorphism, anisonucleosis, and occasional macronucleoli without nuclear enlargement, lack of myxoid stroma, and few naked stromal cells. To avoid cytologic overdiagnosis of fibroadenoma, mild to moderate nuclear pleomorphism without nuclear enlargement, and cellular dissociation without nuclear atypia should not be regarded as criteria of high risk group.

Background: There is a correlation between the severe fever with thrombocytopenia syndrome (SFTS) viral load and disease severity; however, measurement of viral load is difficult in general laboratory and it takes time to obtain a viral load value. Here, the laboratory parameters for predicting the dynamic changes in SFTS viral load were identified.In addition, we tried to evaluate a specific time point for the early determination of clinical deterioration using dynamic change of laboratory parameters. Materials and Methods: This observational study included SFTS patients in Korea (2013 - 2020). Cross-correlation analysis at lagged values was used to determine the temporal correlation between the SFTS viral loads and time-series variables. Fifty-eight SFTS patients were included in the non-severe group (NSG) and 11 in the severe group (SG). Results: In the cross-sectional analyses, 10 parameters -white blood cell, absolute neutrophil cell, lymphocyte, platelet, activated partial thromboplastin time (aPTT), C-reactive protein, aspartate aminotransferase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), and creatine phosphokinase (CPK)- were assessed within 30 days from the onset of symptoms; they exhibited three different correlation patterns: (1) positive, (2) positive with a time lag, and (3) negative. A prediction score system was developed for predicting SFTS fatality based on age and six laboratory variables -platelet, aPTT, AST, ALT, LDH, and CPKin 5 days after the onset of symptoms; this scoring system had 87.5% sensitivity and 86.0% specificity (95% confidence interval: 0.831 - 1.00, P <0.001). Conclusion Three types of correlation patterns between the dynamic changes in SFTS viral load and laboratory parameters were identified. The dynamic changes in the viral load could be predicted using the dynamic changes in these variables, which can be particularly helpful in clinical settings where viral load tests cannot be performed. Also, the proposed scoring system could provide timely treatment to critical patients by rapidly assessing their clinical course.

Holoprosencephaly (HPE) is a rare congenital disorder characterized by the incomplete separation of the prosencephalon. The clinical spectrum of HPE depends on the subtypes observed on imaging, which includes lobar, semilobar, and alobar variants. Cyclopia, the most severe form of alobar HPE, is typically associated with early postnatal death within a few days. We report the case of a female infant was born at 38 weeks and 6 days of gestation, weighing 2,410 g, to a 39-year-old mother via vaginal delivery. She was the second baby of dichorionic-diamniotic twins. The neonate was born with multiple defects including facial anomalies such as cyclopia and arrhinia and was diagnosed with alobar HPE with cyclopia. This condition was suspected prenatally at 17 weeks of gestation and confirmed postnatally using brain magnetic resonance imaging. The cause of death in our patient was aspiration pneumonia with aggravated central apnea, and she survived for 8 months (240 days) with comfort care alone, without aggressive life support. This is the first report of an infant with alobar HPE, cyclopia, and arrhinia surviving for 240 days with only comfort care, marking the longest documented survival for this typically lethal condition without invasive interventions.
