Objectives: This study investigated the effect of Korean medicine on an elderly patient with posterior circulation cerebral infarction, chronic kidney disease (CKD), and early neurological deterioration (END). Methods: The patient, who already had CKD, was treated with Korean medicine, comprising herbal medicine, acupuncture, moxa, and cupping combined with Western medicine (antiplatelet, diabetes) and physical therapy. A manual muscle test (MMT) and a modified Barthel index (MBI) were used to observe the treatment effects, and blood tests were performed to check estimated glomerular filtration rate (eGFR), creatinine and blood urea nitrogen (BUN), which represent renal function. Results: After the treatment, MMT, MBI, and renal function scores had increased. Conclusions: This study suggests that Korean medicine can effectively treat posterior circulation cerebral infarction with END in CKD, but further studies should be conducted.

Purpose: We evaluated the relationship of prostate-specific antigen (PSA) and obesity indices (weight, body mass index [BMI] and waist circumference [WC]) in Korean middle-aged men. Materials and Methods: From February to September 2013, 1,900 police men under 60 years old who participated in a prostate health screening program were included this cross-sectional study. All subjects underwent clinical examinations including weight, height, BMI, WC, fasting blood sugar, lipid profiles, estimated glomerular filtration rate (GFR), and PSA. Total prostate volume (TPV) was assessed clinically. Spearman correlation and multiple linear regression tests were performed to evaluate the obesity indices and PSA relationships. Results: The mean age was $52.0{\pm}4.7years$, and the mean PSA was $0.97{\pm}0.99ng/mL$. The PSA showed a significant positive correlation with the age (r=0.108, p<0.01), TPV (r=0.349, p<0.01), height (r=-0.052, p<0.05), weight (r=0.186, p<0.05), low-density lipoprotein cholesterol (r=0.056, p<0.05), and GFR (r=-0.096, p<0.01). All obesity indices including weight, BMI, and WC showed negative correlations with PSA (beta=-0.013, p<0.001; beta=-0.039, p<0.001; and beta=-0.010, p=0.005; respectively) in age and TPV-adjusted model. Conclusions: Common obesity indices (weight, BMI, and WC) were associated with lower PSA in Korean middle-aged population. Thus, an individual's degree of obesity should be considered when PSA is checked in the first prostate cancer screening of life.

Purpose: Despite meticulous techniques, surgical complications continue to be problematic in kidney transplant recipients. Role of routine stenting to reduce complications is controversial. In this study, we compare incidence of early urological complications, lymphoceles, urinary tract infections (UTI) and graft function; with or without double-J stenting. Materials and Methods: All patients who underwent live related donor renal transplantation from February 2014 to February 2016 were included. Transplants prior to February 2015 were without routine stenting; subsequent transplants were with routine stenting. Patients with neurogenic bladder, previously operated bladder and delayed or low urinary output were excluded. Followup was for at least three months. Descriptive statistics was performed for all parameters. Chi square test and Fisher's Exact test were used for qualitative variables. For quantitative variables, Mann-Whitney test was used to test median difference and independent samples t-test for mean difference. The p-value ${\leq}0.05$ was considered significant. Results: We analysed 74 patients (34 stented and 40 non-stented). There was no difference in the incidence of urinary leak, anastomotic obstruction, lymphoceles or UTI (p>0.4 for all comparisons). However, mean estimated glomerular filtration rate at sixth day, 14th day, one month and two months were 76.1 vs. 61.5 (p=0.025), 72.1 vs. 56.6 (p=0.005), 79.4 vs. 63.1 (p=0.002) and 82.0 vs. 63.3 (p=0.001) in the stented versus non-stented groups. Conclusions: Placement of ureteral stent in renal transplant does not significantly affect the incidence of early urinary complications or UTI. However, graft function is significantly better in stented recipients, at least in the short term.

Purpose: This study compared and analyzed the risk factors that affect a wound healing group and healing failure group. Materials and Methods: From 2010 to 2018, 39 patients who had suffered a single toe amputation were evaluated retrospectively. The patients were divided into two groups (wound healing group and healing failure group - within at least 3 months following the amputation). Regarding the possible risk factors, age, gender, Wagner and Brodsky classifications, duration of diabetes mellitus, whether the patient had peripheral arterial occlusive disease (PAOD) or cardiovascular disease, body mass index, HbA1c, total cholesterol, estimated glomerular filtration rate (eGFR), blood urea nitrogen (BUN), smoking, and alcohol were investigated. Results: The mean duration of diabetes mellitus was 140 months in the healing group and 227 months in the healing failure group, and the duration of diabetes was significantly longer in the failure group (p=0.009). A significant difference in eGFR was observed between the two groups ($59.17mL/min/1.73m^2$ in the healing group and $31.1mL/min/1.73m^2$ in the failure group) (p=0.022). Sixteen patients with PAOD were found, all 10 patients in the healing failure group were PAOD patients. Conclusion: To reduce the additional complications in single toe amputation patients, the underlying disease and appropriate treatment are the most important factors. In addition, a more proximal level of amputation also should be considered in cases of patients with PAOD, high BUN and low eGFR, and patients with long-term diabetes.

Renal cortical necrosis (RCN) is patchy or diffuse ischemic destruction of the renal cortex caused by significantly reduced renal arterial perfusion. It is a rare cause of acute kidney injury (AKI) and is associated with high mortality. Here, we review the case of RCN in a 15-year-old boy who developed AKI. A 15-year-old boy was referred to our hospital from a local hospital due to a sharp decrease in his renal function. He presented with acute flank pain, nausea with vomiting, and oliguria for the past two days. He had taken a single dose of antihistamine for nasal congestion. At our hospital, his peak blood pressure was 148/83 mmHg and he had a high body mass index of $32.9kg/m^2$. The laboratory data showed a blood urea nitrogen (BUN) of 28.4 mg/dL, a creatinine of 4.26 mg/dL, and a glomerular filtration rate estimated from the serum cystatin C of $20.2mL/min/1.73m^2$. Proteinuria (spot urine protein to creatinine ratio 1.66) with pyuria was observed. Kidney sonography showed parenchymal swelling and increased renal echogenicity. Due to rapidly progressing nephritis, steroid pulse therapy (750 mg/IV) was done on the second day of his admission and the patient showed complete recovery with normal renal function. However, the kidney biopsy findings revealed renal cortical hemorrhagic necrosis. Multifocal, relatively well-circumscribed, hemorrhagic necrotic areas (about 25%) were detected in the tubulointerstitium. Although RCN is an unusual cause of AKI, especially in children, pediatricians should consider the possibility of RCN when evaluating patients with rapidly decreasing renal function.

Liraglutide (Saxenda^R) is prescribed to induce and sustain weight loss in obese patients. The starting dose of liraglutide is 0.6 mg/day for 1 week, which is increased by 0.6 mg/day every week until the full maintenance dose of 3 mg/day is achieved. Such dose titration is needed to prevent side effects, which primarily include gastrointestinal problems such as nausea, diarrhea, constipation, vomiting, dyspepsia, and abdominal pain. A 35-year-old, reportedly healthy obese man receiving liraglutide treatment for obesity visited the emergency room complaining of generalized weakness and dizziness accompanied by repeated diarrhea and vomiting. He reported over 20 episodes of diarrhea starting the day after liraglutide dose escalation from 1.2 mg/day to 1.8 mg/day. Laboratory findings suggested pre-renal acute kidney injury, including serum creatinine 4.77 mg/dl, blood urea nitrogen (BUN) 37 mg/dl, estimated glomerular filtration rate (eGFR) 15 ml/min/1.73 m², and Fractional excretion of sodium 0.08. After volume repletion therapy, his renal function recovered to a normal range with laboratory values of creatinine 1.08 mg/dl, BUN 14 mg/dl, and eGFR 88 ml/min/1.73 m². This case emphasizes the need for caution when prescribing glucagon-like peptide-1 receptor agonists, including liraglutide, given the risk of serious renal impairments induced by volume depletion and dehydration through severe-grade diarrhea and vomiting.

Objectives: Although a few studies have investigated the relationship between kidney and oral function (number of remaining teeth), their results remain inconclusive. Therefore, this study aimed to investigate the relationship between kidney function and oral health in community-dwelling healthy elderlies and examine the factors associated with kidney function. Materials and Methods: We used cross-sectional data from the Shimane prefecture cohort recruited by the Center for Community-Based Health Research and Education in 2019. We collected clinical data on dental status, background factors and kidney function (estimated glomerular filtration rate [eGFR], mL/min/1.73 m² and creatinine levels, mg/dL). Results: The study enrolled 481 participants, whose mean age was 66.7±7.4 years, and 223 (46.4%) participants were men. Multivariate analysis revealed significant correlations between eGFR (B=0.17, P=0.04), creatinine (B=-0.54, P<0.01), and the number of remaining teeth. The number of remaining teeth was associated with creatinine and eGFR, which are indicators of kidney function. Conclusion: This study suggests that preserving the teeth may prevent decline in kidney function. Dental professionals should provide instructions and professional care to reduce the risk of systemic diseases such as kidney dysfunction.

일반적으로 요중 카드뮴 농도는 요비중 또는 요중 크레아티닌 농도로 보정한 값을 사용해왔다. 그러나 어떤 보정방법이 더 타당한지에 대한 논란은 계속되고 있다. 본 연구에서는 비교적 큰 규모의 일반인구집단을 대상으로 요중 카드뮴농도와 각종 신장손상지표들과의 관련성을 평가함에 있어 요비중 보정 방법과 요중 크레아티닌 보정 방법 중 어느 방법이 더 타당한지 비교 평가하였다. 1,086명의 자원자 중 신장질환의 질병력이 있는 사람을 제외한 862명이 최종적으로 연구대상에 포함되었다. 대상자들로부터 측정한 요중 카드뮴 농도 및 malondialdehyde (MDA), N-acetyl-${\beta}$-D-glucosaminidase 농도, 혈중 크레아티닌을 이용하여 산출한 사구체여과율 등의 신장손상지표들간의 관련성을 평가하였다. 연구 결과, 요중 크레아티닌 농도보다는 요비중으로 보정한 카드뮴 농도가 각종 신장손상지표와 높은 상관성이 있음을 보여주었다. 특히, 요비중 보정 카드뮴 농도는 요중 MDA 농도와 양의 상관관계를, 사구체여과율과는 음의 상관관계를 보여주었다. 이러한 결과는 일반인구집단에서 카드뮴 노출이 많아질수록 사구체여과율이 감소함을 의미하며 이러한 기전에서 산화적스트레스가 관여하고 있음을 보여준다. 또한, 사구체여과율이 카드뮴 노출에 의한 유용한 신장손상지표 중 하나로 사용될 수 있음을 의미한다.
