Birth injury is defined as any condition that affects the fetus adversely during the labor or delivery. Clavicle fracture during the delivery can be found in 0.49-0.95% if all living newborns. The objectives of this study were to identify and prevent the contribution facture during delivery. We obtained 98 patients of the clavicle fracture among the 13,698 neonates delivered at P.M.C from March. 1991 to Feb. 1994. We analysed the 98 patients of the clavicle fracture with 857 control group according to neonatal factors, maternal factors and methods of delivery. The results were as follows ; 1. Of all the cases of the clavicle fracture, the site of the fracture was middle 1/3 of the clavicle and majority of the fracture were displaced(82.5%). 2. Birth injuries which were associated with clavicle fracture were increased than those without clavicle fracture in brachial plexus injuries, scalp and intracranial hemorrhage, and skull fracture. 3. Contributing factors which were increased the fracture of the clavicle during the delivery were as follows; i) Maternal age over 37 years and below 24 years. ii) Gestational age over 40 weeks (especially over 42 weeks) iii) Birth weight over 3500kg. 4. The proportion of the vacuum extraction during the delivery was nearly double times in patient group than in control group.

Purpose:
The aims of this study were to investigate the clinical value of Rab27a as a urinary biomarker, and its efficiency in the prediction of bladder cancer grade.
Materials and Methods:
The expression of Rab27a in urine samples of patients with bladder cancer, cell line (T-24), and tissue samples of patients with bladder cancer was estimated via quantitative reverse transcription polymerase chain reaction (qRT-PCR). The Rab27a expression level was investigated according to sex, age, and histological grade via qRT-PCR and Western blotting.
Results:
Rab27a was also expressed at high levels in urine compared to cell lines and tissues from bladder cancer patients. In addition, Rab27a expression varied significantly according to tumor grade (p<0.001). Rab27a was expressed at high levels in male and elderly patients, however, there was not statistically significant.
Conclusions
Our results indicated that Rab27a is valuable as a urinary diagnostic biomarker for bladder cancer. In addition, it may serve as a predictive factor for determining bladder cancer grade.

Background:
This study investigated the incidence of endocrine immune-related adverse events (irAEs) for recently developed immune checkpoint inhibitor (ICI) drugs.
Methods:
We collected studies on newly developed ICI drugs using PubMed/Medline, Embase, and Cochrane Library from inception through January 31, 2023. Among ICI drugs, nivolumab, pembrolizumab, and ipilimumab were excluded from the new ICI drugs because many papers on endocrine-related side effects have already been published.
Results:
A total of 44,595 patients from 177 studies were included in this analysis. The incidence of hypothyroidism was 10.1% (95% confidence interval [CI], 8.9% to 11.4%), thyrotoxicosis was 4.6% (95% CI, 3.8% to 5.7%), hypophysitis was 0.8% (95% CI, 0.5% to 1.1%), adrenal insufficiency was 0.9% (95% CI, 0.7% to 1.1%), and hyperglycemia was 2.3% (95% CI, 1.6% to 3.4%). Hypothyroidism and thyrotoxicosis occurred most frequently with programmed cell death protein-1 (PD-1) inhibitors (13.7% and 7.5%, respectively). The rate of endocrine side effects for the combination of a programmed death-ligand 1 inhibitor (durvalumab) and cytotoxic T lymphocyte-associated antigen 4 inhibitor (tremelimumab) was higher than that of monotherapy. In a meta-analysis, the combination of tremelimumab and durvalumab had a 9- to 10-fold higher risk of pituitary and adrenal-related side effects than durvalumab alone.
Conclusion
Newly developed PD-1 inhibitors had a high incidence of thyroid-related irAEs, and combined treatment with durvalumab and tremelimumab increased the risk of pituitary- and adrenal-related irAEs. Based on these facts, it is necessary to predict the endocrine side effects corresponding to each ICI drug, diagnose and treat them appropriately, and try to reduce the morbidity and mortality of patients.

BACKGROUND: Diabetic nephropathy (DN) is the most serious microvascular complication of diabetes mellitus and is one of the leading causes of end stage renal failure. In previous studies, the contribution of genetic susceptibility to DN showed inconsistent results. In this study, we investigated the association between the solute carrier family 2 facilitated glucose transporter member 1 (SLC2A1) HaeIII polymorphism and DN in Korean patients with type 2 diabetes mellitus (T2DM) according to disease duration. METHODS: A total of 846 patients with T2DM (mean age, 61.3 ± 12.3 years; mean duration of T2DM, 10.3 ± 7.9 years; 55.3% men) who visited the Chungbuk National University Hospital were investigated. The HaeIII polymorphism of the SLC2A1 gene was determined by the real time polymerase chain reaction method. Genotyping results were presented as GG, AG, or AA. A subgroup analysis was performed according to duration of T2DM (≤ 10 years, < 10 years). RESULTS: The AG + AA genotype showed a significantly higher risk of DN compared with the GG genotype in patients with a type 2 DM duration less than 10 years (12.4% vs. 4.2%; P < 0.001). No significant differences were observed in terms of other diabetic complications, including retinopathy, peripheral neuropathy, cardiovascular disease, cerebrovascular disease or peripheral artery disease, according to the genotypes of the SLC2A1 HaeIII polymorphism. CONCLUSION: The SLC2A1 HaeIII polymorphism was associated with DN in Korean patients with T2DM, particularly in the group with a relatively short disease duration.

PURPOSE: To evaluate the functional changes, postop delirium and complications after cemented bipolar hemiarthroplasty for the femur neck fractures in patients aged around ninety. MATERIALS AND METHODS: Between May 1995 and April 2002, of the twenty seven patients, 17 who follow-up for at least one year were included in this study. Walking ability, activity of daily living, mental status, chronic illness, postoperative delirium and complications were evaluated retrospectively using Yoon's walking class, ADL scale, MMSE-K score, ASA classification, DSM IV respectively. RESULTS: The walking ability was decreased to 2.4 from 3.3 tendency of reliance in ADL scale was increased to 8.3 from 4.5, MMSE-K score was decreased to 15.9 from 21.7. There was no significant change in status of chronic illness. Postoperative delirium occurred in eight (47%) cases and all of them recovered completely. complications included bladder problem in eleven (66%) cases, temporary respiratory distress in two (12%) cases, hip dislocation in two (12%) cases, infection in one (6%) case. Overall thirteen (78%) cases were able to walk with supports. CONCLUSION: This study indicates that physicians treation femur neck fractures in patients aged around ninety must anticipate worsening of the functional changes more especially in regard to walking level, activity of daily living and mental status, little changes of chronic disease status, complete recovery of postop delirium and high complication rate

Background:
Conventional diagnostic approaches for adrenal tumors require multi-step processes, including imaging studies and dynamic hormone tests. Therefore, this study aimed to discriminate adrenal tumors from a single blood sample based on the combination of liquid chromatography-mass spectrometry (LC-MS) and machine learning algorithms in serum profiling of adrenal steroids.
Methods:
The LC-MS-based steroid profiling was applied to serum samples obtained from patients with nonfunctioning adenoma (NFA, n=73), Cushing’s syndrome (CS, n=30), and primary aldosteronism (PA, n=40) in a prospective multicenter study of adrenal disease. The decision tree (DT), random forest (RF), and extreme gradient boost (XGBoost) were performed to categorize the subtypes of adrenal tumors.
Results:
The CS group showed higher serum levels of 11-deoxycortisol than the NFA group, and increased levels of tetrahydrocortisone (THE), 20α-dihydrocortisol, and 6β-hydroxycortisol were found in the PA group. However, the CS group showed lower levels of dehydroepiandrosterone (DHEA) and its sulfate derivative (DHEA-S) than both the NFA and PA groups. Patients with PA expressed higher serum 18-hydroxycortisol and DHEA but lower THE than NFA patients. The balanced accuracies of DT, RF, and XGBoost for classifying each type were 78%, 96%, and 97%, respectively. In receiver operating characteristics (ROC) analysis for CS, XGBoost, and RF showed a significantly greater diagnostic power than the DT. However, in ROC analysis for PA, only RF exhibited better diagnostic performance than DT.
Conclusion
The combination of LC-MS-based steroid profiling with machine learning algorithms could be a promising one-step diagnostic approach for the classification of adrenal tumor subtypes.

Background:
This systematic review was conducted to identify and summarize key factors, including economic methods, topics, results, and indicators, within relevant economic evaluation research on thyroid cancer.
Materials and Methods:
A literature search on the economic evaluation of thyroid cancer treatment was conducted using the MEDLINE database up to May 2021. Data on population, intervention, comparison, outcome, time, setting, and study design were extracted from each study. The economic evaluation method in each study was re-classified according to the theoretical criteria defined by the international economic evaluation guidelines.
Results:
A total of 49 studies were included, involving cost analysis (CA, n=9), cost-minimization analysis (CMA, n=3), cost-effectiveness analysis (CEA, n=29), and cost-utility analysis (CUA, n=8). When CEA and CUA were classified as one method, the consistency between the methods of the reviewers based on the theoretical criteria and those from the original studies was 77% (95% confidence interval, 0.63-0.92). Most studies dealt with specific period-related controversial issues including comparison between treatment strategies, and cost-effectiveness of the prophylactic central neck dissection, molecular testing, and rhTSH. Contrasting results have been obtained when different economic evaluation methods were applied for the same topic (e.g., total thyroidectomy [TT] was more dominant than hemithyroidectomy [HT] in CEA, but HT was more dominant than TT in CUA), and different clinical and economic inputs were applied. All studies included direct medical costs, which were mostly derived from Medicare and input probabilities in each economic model, and utility scores for outcomes were mostly based on literature reviews.Few studies included non-medical direct costs and indirect costs.
Conclusion
Our systematic review provides information on how to design and proceed to overcome the limitations of existing studies and ensure validity.

BACKGROUND: In approach to an adrenal incidentaloma, early exclusion of pheochromocytoma is clinically important, due to the risk of catecholamine crisis. The aims of this study are to investigate the characteristics of incidentally detected pheochromocytomas, compared with that of the other adrenal incidentalomas, and to compare these characteristics with those of symptomatic pheochromocytomas. METHODS: In this retrospective study, we reviewed the medical records of 198 patients with adrenal incidentaloma from 2001 to 2010. We analyzed the clinical, laboratory and radiological data of pheochromocytomas, in comparison with those of the other adrenal incidentalomas. We also compared the characteristics of these incidentally detected pheochromocytomas with the medical records of 28 pathologically proven pheochromocytomas, diagnosed based on typical symptoms. RESULTS: Among the 198 patients with adrenal incidentaloma, nineteen patients were diagnosed with pheochromocytoma. Pheochromocytomas showed larger size and higher Hounsfield unit at precontrast computed tomography (CT) than did non-pheochromocytomas. All pheochromocytomas were larger than 2.0 cm, and the Hounsfield units were 19 or higher in precontrast CT. When both criteria of size > 2.0 cm and Hounsfield unit > 19 were met, the sensitivity and specificity for the diagnosis of pheochromocytoma were 100% and 79.3%, respectively. Compared with patients with pheochromocytoma, diagnosed based on typical symptoms, patients with incidentally detected pheochromocytoma were older, presented less often with hypertension, and showed lower levels of 24-hour urine metanephrine. CONCLUSION: Adrenal incidentaloma with < 2.0 cm in size or < or = 19 Hounsfield units in precontrast CT imaging was less likely to be a pheochromocytoma. Patients with incidentally discovered pheochromocytoma showed lower catecholamine metabolites, compared with those patients with symptomatic pheochromocytoma.
