		                        			 We report a case of a ruptured triple hormone-secreting adrenal mass with hyperaldosteronism, hypercortisolism, and elevated normetanephrine levels, diagnosed as adrenal cortical carcinoma (ACC) by histology. A 53-year-old male patient who initially presented with abdominal pain was referred to our hospital for angiocoagulation of an adrenal mass rupture. Abdominal computed tomography revealed a heterogeneous 19×11×15 cm right adrenal mass with invasion into the right lobe of the liver, inferior vena cava, retrocaval lymph nodes, and aortocaval lymph nodes. Angiocoagulation was performed. Laboratory evaluation revealed excess cortisol via a positive 1-mg overnight dexamethasone suppression test, primary hyperaldosteronism via a positive saline infusion test, and plasma normetanephrine levels three times higher than normal. An adrenal mass biopsy was performed for pathological confirmation to commence palliative chemotherapy because surgical management was not deemed appropriate considering the extent of the tumor. Pathological examination revealed stage T4N1M1 ACC. The patient started the first cycle of adjuvant mitotane therapy along with adjuvant treatment with doxorubicin, cisplatin, and etoposide, and was discharged. Clinical cases of dual cortisol- and aldosterone-secreting ACCs or ACCs presenting as pheochromocytomas have occasionally been reported; however, both are rare. Moreover, to the best of our knowledge, a triple hormone-secreting ACC has not yet been reported. Here, we report a rare case and its management. This case report underscores the necessity of performing comprehensive clinical and biochemical hormone evaluations in patients with adrenal masses because ACC can present with multiple hormone elevations.

		                        			 Purpose:
		                        			To investigate the relative risks (RRs) for dementia among individuals with glaucoma. 
		                        		
		                        			Methods:
		                        			We conducted a search of PubMed, Web of Science, Scopus, and Cochrane databases for observational cohort studies examining the association between glaucoma and dementia until March 2023. Two authors independently screened all titles and abstracts according to predefined inclusion and exclusion criteria. Pooled RR and 95% confidence intervals (CIs) were generated using random-effect models. 
		                        		
		                        			Results:
		                        			The meta-analysis included 18 cohort studies conducted in eight countries and involving 4,975,325 individuals. The pooled RR for the association between glaucoma and all-cause dementia was 1.314 (95% CI, 1.099–1.572; I2 = 95%). The pooled RRs for the associations of open-angle glaucoma with Alzheimer dementia and Parkinson disease were 1.287 (95% CI, 1.007–1.646; I2 = 96%) and 1.233 (95% CI, 0.677–2.243; I2 = 73%), respectively. The pooled RRs for the associations of angle-closure glaucoma with all-cause dementia and Alzheimer dementia were 0.978 (95% CI, 0.750–1.277; I2 = 17%) and 0.838 (95% CI, 0.421–1.669; I2 = 16%), respectively. No evidence of publication bias was detected in the Begg-Mazumdar adjusted rank correlation test (p = 0.47). 
		                        		
		                        			Conclusions
		                        			Based on current observational cohort studies, there is evidence supporting that glaucoma is a risk factor for dementia in the adult population.

		                        			 Purpose:
		                        			To report a rare case of severe ocular hypertension following intravenous methylprednisolone treatment in a child with bilateral optic neuritis.Case summary: A 6-year-old girl presented with bilateral severe visual loss and disc swelling. Magnetic resonance imaging revealed optic nerve enhancement, and she received high-dose intravenous methylprednisolone for 3 days and oral prednisolone 30 mg/day for 2 weeks. Two weeks after initiating treatment, ophthalmologic examination revealed an intraocular pressure (IOP) of 46 mmHg in the right eye and 42 mmHg in the left eye. The best-corrected visual acuity was 1.0 in the right eye and 0.6 in the left eye. Relative afferent pupillary defect was noted in the left eye. Fundus examination showed normal cup-to-disc ratio (0.4) in both eyes. The iridocorneal angle was open in all directions. The treatment plan included the cessation of oral prednisolone and initiation of latanoprost and dorzolamide-timolol fixed combination agent. After 12 hours, the IOP decreased to 18 mmHg in the right eye and 14 mmHg in the left eye. Six months later, her visual acuity was 1.0 in both eyes, and IOP was maintained at 11 and 13 mmHg in the right and left eye, respectively. Optic disc examination showed no sign of glaucomatous change with normal cup-to disc ratio in both eyes. 
		                        		
		                        			Conclusions
		                        			Since steroid medication may cause asymptomatic IOP elevation, regular intraocular pressure measurements are required during steroid treatment for pediatric optic neuritis. The administration of IOP-lowering eyedrops returned IOP to the normal range without damaging the optic nerve.

		                        			Resistance to thyroid hormone (RTH) is a condition caused by a mutation in the thyroid hormone receptor gene. It is rarely reported in individuals with no family history of RTH or in premature infants, and its clinical presentation varies. In our case, a premature infant with no family history of thyroid diseases had a thyroid stimulating hormone level of 85.0 µIU/mL and free thyroxine level of 1.64 ng/dL on a thyroid function test. The patient also presented with clinical signs of hypothyroidism, including difficulties in feeding and weight gain. The patient was treated with levothyroxine; however, only free thyroxine and triiodothyronine levels increased without a decrease in thyroid-stimulating hormone levels. Taken together with thyroid gland hypertrophy observed on a previous ultrasound examination, RTH was suspected and the diagnosis was eventually made based on a genetic test. A de novo mutation in the thyroid hormone receptor β gene in the infant was found that has not been previously reported. Other symptoms included tachycardia and pulmonary hypertension, but gradual improvement in the symptoms was observed after liothyronine administration. This report describes a case involving a premature infant with RTH and a de novo mutation, with no family history of thyroid disease.

		                        			BACKGROUND: Transient elastography (FibroScan®) is a non-invasive and rapid method for assessing liver fibrosis. While the feasibility and usefulness of FibroScan® have been proven in adults, few studies have focused on pediatric populations. We aimed to determine the feasibility and usefulness of FibroScan® in Korean children. METHODS: FibroScan® examinations were performed in 106 children (age, 5–15 years) who visited the Konyang University Hospital between June and September 2018. Liver steatosis was measured in terms of the controlled attenuation parameter (CAP), while hepatic fibrosis was evaluated in terms of the liver stiffness measurement (LSM). Children were stratified into obese and non-obese controls, according to body mass index (≥ or < 95th percentile, respectively). RESULTS: The obese group was characterized by significantly higher levels of aspartate aminotransferase (AST, 57.00 ± 48.47 vs. 26.40 ± 11.80 IU/L; P < 0.001) and alanine aminotransferase (ALT, 91.27 ± 97.67 vs. 16.28 ± 9.78 IU/L; P < 0.001), frequency of hypertension and abdominal obesity (abdominal circumference > 95% percentile) (P < 0.001), CAP (244.4–340.98 dB/m), and LSM (3.85–7.77 kPa) (P < 0.001). On FibroScan®, 30 of 59 obese children had fibrosis (LSM > 5.5 kPa), whereas the remaining 29 did not (LSM < 5.5 kPa). Obese children with fibrosis had higher levels of AST (73.57 ± 56.00 vs. 39.86 ± 31.93 IU/L; P = 0.009), ALT (132.47 ± 113.88 vs. 48.66 ± 51.29 IU/L; P = 0.001), and gamma-glutamyl transferase (106.67 ± 69.31 vs. 28.80 ± 24.26 IU/L; P = 0.042) compared to obese children without fibrosis. LSM had high and significant correlation (P < 0.05) with AST, ALT, homeostasis model assessment for insulin resistance, and AST-to-platelet ratio index. CONCLUSION: FibroScan® is clinically feasible and facilitates non-invasive, rapid, reproducible, and reliable detection of hepatic steatosis and liver fibrosis in the Korean pediatric population.

		                        			Fanconi syndrome is a dysfunction of the proximal renal tubules that results in impaired reabsorption and increased urinary loss of phosphate and other solutes. The pathophysiology of drug-induced Fanconi syndrome is unclear. Here we report the case of a 36-year-old woman who presented with pain in multiple bones and proteinuria. She had a 7-year history of taking adefovir at 10 mg/day for chronic hepatitis B. Three years previously she had received surgery for a nontraumatic right femur neck fracture, after which she continued to complain of pain in multiple bones, and proteinuria, glycosuria, and phosphaturia were noted. The findings of a light-microscope examination of a renal biopsy sample were normal, but mitochondrial damage of the proximal tubules was evident in electron microscopy. Western blot analysis revealed that the level of serum fibroblast growth factor 23 (FGF23) was lower than in normal controls. After 2 months of treatment, hypophosphatemia and proximal tubular dysfunction were reversed, and serum FGF23 had normalized. This case suggests that direct mitochondrial damage in proximal tubules can cause drug-induced Fanconi syndrome associated with osteomalacia.

		                        			BACKGROUND: Diabetes can be efficiently prevented by life style modification and medical therapy. So, identification for high risk subjects for incident type 2 diabetes is important. The aim of this study is to identify the best β-cell function index to identify high risk subjects in non-diabetic Koreans. METHODS: This is a retrospective longitudinal study. Total 140 non-diabetic subjects who underwent standard 2-hour 75 g oral glucose tolerance test from January 2007 to February 2007 at Kangbuk Samsung Hospital and followed up for more than 1 year were analyzed (mean follow-up, 54.9±16.4 months). The subjects were consist of subjects with normal glucose tolerance (n=44) and subjects with prediabetes (n=97) who were 20 years of age or older. Samples for insulin and C-peptide levels were obtained at 0 and 30 minutes at baseline. RESULTS: Thirty subjects out of 140 subjects (21.4%) developed type 2 diabetes. When insulin-based index and C-peptide-based index are compared between progressor and non-progressor to diabetes, all C-peptide-based indices were statistically different between two groups, but only insulinogenic index and disposition index among insulin-based index were statistically different. C-peptide-based index had higher value of area under receiver operating characteristic curve (AROC) value than that of insulin-based index. "C-peptidogenic" index had highest AROC value among indices (AROC, 0.850; 95% confidence interval, 0.761 to 0.915). C-peptidogenic index had significantly higher AROC than insulinogenic index (0.850 vs. 0.731 respectively; P=0.014). CONCLUSION: C-peptide-based index was more closely related to incident type 2 diabetes in non-diabetic subjects than insulin-based index.

		                        			PURPOSE: Rib and sternal fractures are common complications of chest compressions during cardiopulmonary resuscitation (CPR). The aim of this study is to investigate skeletal chest injuries following chest compressions and factors associated with skeletal chest injuries. METHODS: A retrospective study was conducted for 10 years from January 2005 to February 2015. Skeletal chest injuries in patients who underwent computerized tomography (CT) after return of spontaneous circulation (ROSC) were analyzed. The exclusion criteria were patients with insufficient medical records, under 18 years old, traumatic cardiac arrest, and out-of-hospital cardiac arrest. RESULTS: During the period 106 patients were included. The CT scan after ROSC showed that 47 patients (44.3%) had rib fractures, and 20 patients (18.9%) had sternal fractures. The rib fracture group showed higher age (73 vs 61, p<0.001), longer CPR time (10 vs 6 min, p<0.001), and higher incidence of sternal fracture (34% vs 6.8%, p<0.001). The sternal fracture group showed longer CPR time (10 vs 7, p<0.05) and higher incidence of rib fractures (80% vs 4.7%, p<0.001). In multivariate logistic regression analysis, age (OR 1.087; 95% CI 1.041 to 1.134, p<0.001), CPR time (OR 1.200; 95% CI 1.087 to 1.323, p<0.001), and sternal fracture (OR 4.524; 95% CI 1.259 to 16.697, p=0.021) showed significant association with rib fracture. CONCLUSION: Rib and sternal fractures are frequent complications in patients who underwent CPR. In hospital cardiac arrest patients with older age, longer CPR time, and sternal fracture needed more precaution for rib fractures and other complications.

		                        			PURPOSE: To evaluate the clinical usefulness of KCL 990(R) for the treatment of dry eye with meibomian gland dysfunction (MGD). METHODS: Patients (n = 54 eyes, 27 subjects) diagnosed with dry eye with MGD were recruited for a prospective, one-month clinical trial. Patients received a twice-a-day 15-minute treatment using the KCL 990(R). Effectiveness parameters included patient symptom scores using the Ocular Surface Disease Index (OSDI) questionnaires, tear osmolarity measured with TearLab(R) (TearLab Corporation, San Diego, CA, USA), classical tear break-up time (TBUT), and objective TBUT value using an Optical Quality Analysis System (OQAS(R), Visiometrics, Castelldefels, Spain). Data are presented for pre-treatment (baseline) and at 1 week and 1 month post-treatment. An objective TBUT value was estimated in each eye when the optical scattering index (OSI) started to increase consistently, and data were obtained at pretreatment (baseline) and at 1 month post-treatment. RESULTS: The symptom scores on OSDI questionnaires, tear osmolarity, and tear break-up time improved significantly from baseline to one week (p < 0.05). This improvement was maintained with no significant regression at 1 month (p < 0.05). The objective TBUT value decreased significantly at 1 month (p < 0.05). CONCLUSIONS: KCL 990(R) contributed to improve not only signs and symptoms of dry eye with MGD, but also the function of the tear film and ocular surface.

		                        			OBJECTIVES: The aim of this study is to develop Treatment Guidelines for Alcohol Use Disorder-the Korean Addiction Treatment Guidelines-using the Adaptation method. METHODS AND PROCEDURES: As the Adaptation method of Guidelines, the ADAPTE Manual, which is developed by ADAPTE collaboration is applied. In Part 1 : preparatory work prior to the beginning of Adaptation is performed. In Part 2 : the core phase of the Adaptation in which we searched the guidelines and performed a systematic review of the literature. The two guidelines (of the AU and the UK) are selected by gone through the methodological quality and currency evaluation for guidelines. And, in order to choose the proper recommendations, the contents were evaluated with regard to the applicability and acceptability of guidelines to the domestic. Finally, in Part 3 : the adapted guideline is reviewed externally, with review and plan update. Therefore, in this way, the Korean Guidelines for Treatment of Alcohol Use Disorder, comprised of 55 recommendations, was developed. CONCLUSION: In this study, Korean Guidelines for Treatment of Alcohol Use Disorder were developed by application of the Adaptation method of ADAPTE. These are the first evidence-based Korean Guidelines for Treatment of Alcohol Use Disorder, which were modified and accepted in accordance with Korean circumstances within the range not damaging the validity of the treatment worth, and it is expected to contribute to improvement in quality and efficiency enhancement of Korean treatment of Alcohol Use Disorder.
