Association between the Eating Family Meal and the Prevalence of Metabolic Syndrome Using Data from Korea National Health and Nutrition Examination Survey (2007–2012) / 가정의학회지

BACKGROUND: Several studies have shown that family meals promote a well-balanced and healthier diet and weight status. Metabolic syndrome is related to eating behavior. This study investigated the association between eating family meals and the prevalence of metabolic syndrome. METHODS: This cross-sectional study included 4,529 subjects who participated in the Korea National Health and Nutrition Examination Survey IV and V (2007–2012). A self-reported questionnaire was used to assess dietary status. Metabolic syndrome was defined according to the guidelines of the modified version of the National Cholesterol Education Program Adult Treatment Panel III. We compared the overall quality of dietary intake in family meal. RESULTS: Nutritional adequacy ratios for energy, protein, calcium, vitamin A, vitamin B₁, vitamin B₂, vitamin C, niacin, and potassium, and the mean adequacy ratio were significantly higher in the family meal group (P<0.05). The prevalence of metabolic syndrome was lower in the family meal group (P<0.05). However, we observed no significant association between eating family meals and the prevalence of metabolic syndrome. CONCLUSION: This study demonstrated that eating family meals appeared to be associated with nutrient adequacy. However, we observed no significant differences in prevalence of metabolic syndrome between the 2 groups.

Efficacy of horse chestnut leaf extract ALH-L1005 as a matrix metalloproteinase inhibitor in ligature-induced periodontitis in canine model

Matrix metalloproteinases (MMPs) are the main proteinases associated with periodontal tissue destruction and remodeling. Therefore, inhibition of host-derived MMPs has a key role in the prevention and reduction of periodontitis progression. Horse chestnut (Aesculus hippocastanum L.) extracts have been used as treatments for inflammatory disease, traditionally. This study assessed the clinical effect as a MMP inhibitor of horse chestnut leaf extract ALH-L1005 on periodontitis. ALH-L1005 was obtained from horse chestnut leaf and its MMP inhibitory activities estimated. Periodontitis was induced in beagles assigned to 4 groups and medicated for 6 weeks: low dose test (LT; ALH-L1005, 100 mg/kg/day), high dose test (HT; ALH-L1005, 200 mg/kg/day), positive control (PC; doxycycline, 10 mg/kg/day), or negative control (NC; placebo). Before and after administration, clinical indices of the teeth and MMP quantity in gingival tissues using zymography were measured. Clinical conditions of the LT, HT, and PC groups were significantly improved after 6 weeks. In zymographic evaluations, gelatinolytic and caseinolytic activities were suppressed in LT, HT, and PC groups but not in the NC group. The results suggest that ALH-L1005 could be an effective agent for clinical prevention and treatment of periodontitis by inhibiting the gelatinase and collagenase activities, which can detach periodontal ligaments from alveolar bone.

Current status of human papillomavirus vaccines

Cervical cancer is a malignant neoplasm arising from cells that originate in the cervix uteri. It is the second most prevalent cancer among women. It can have several causes; an infection with some type of human papillomavirus (HPV) is the greatest risk factor for cervical cancer. Over 100 types of HPVs have been identified, and more than 40 types of HPVs are typically transmitted through sexual contact and infect the anogenital region. Among these, a number of HPVs types, containing types 16 and 18, are classified as "high-risk" HPVs that can cause cervical cancer. The HPVs vaccine prevents infection with certain species of HPVs associated with the development of cervical cancer, genital warts, and some less common cancers. Two HPVs vaccines are currently on the global market: quadrivalent HPVs vaccine and bivalent HPV vaccine that use virus-like particles as a vaccine antigen. This review discusses the current status of HPVs vaccines on the global market, clinical trials, and the future of HPVs vaccine development.

A Case of Incidentally Diagnosed Adrenal Paragonimiasis

We report here on a rare case of adrenal paragonimiasis that presented with an adrenal incidentaloma. A 52-year-old male presented with fatigue and weight loss. The laboratory findings revealed eosinophilia (8.5%) and an increased eosinophil count (910/microL). The computed tomography scan showed 6.5 x 5 cm sized multilocular cystic mass in the right adrenal gland, which was non-functioning, and cystic lesions with variable sizes were also noted in the abdominal cavity. On the surgical field, whitish patches were spread out in the peritoneum, the omentum, the dome of the liver and the diaphragm. The right adrenal gland was replaced by a cystic mass filled with mucopurulent creamy materials. The pathologic findings revealed numerous eggs of Paragonimus spp. Also, the ELISA was positive for IgG paragonimus antibody. The adrenal gland can become infected by various microbial pathogens, including parasites, although it is relatively uncommon. However, in the case of a cystic adrenal mass with accompanying eosinophilia in an endemic area, clinicians should consider the possibility of parasitic infection.

Average Daily Risk Range-Index of Glycemic Variability-Related Factor in Type 2 Diabetic Inpatients / 당뇨병

BACKGROUND: It is known that chronic sustained hyperglycemia and its consequent oxidative stress causes diabetic complication in type 2 diabetes. It has been further proven that glycemic variability causes oxidative stress. The aim of this study is to measure the average daily risk range (ADDR)-index of glycemic variability, and to evaluate relevant variables. METHODS: We measured the blood glucose level of type 2 diabetic patients who were treated with multiple daily injections from January to July, 2008. The blood glucose levels were checked four times a day for 14 days and were conversed according to the ADRR formula. The degree of glycemic variability was categorized into non-fluctuation and fluctuation groups. We collected patient data on age, sex, duration of diabetes, body mass index, HOMA(IR), HOMA(betacell) and HbA1c. RESULTS: A total of 97 patients were enrolled in this study. The mean age, duration of diabetes, HbA1c and mean ADRR were 57.6 +/- 13.4, 11.5 +/- 8.5 years, 10.7 +/- 2.5%, and 26.6 +/- 9.8, respectively. We classified 18.5% of the patients to the non-fluctuation group, and 81.5% to the fluctuation group. ADRR was significantly correlated with duration of diabetes, fasting and postprandial glucose, fructosamine, HbA1c and BMI and HOMAbetacell. In addition, this study confirmed that BMI, HOMAbetacell and HbA1c were ADRR-related independent variables. CONCLUSION: ADRR can be used as an index for blood glucose fluctuation in type 2 diabetic patients. Measuring ADRR in patients with low BMI and a long duration of diabetes is helpful to improve the effectiveness of their care.

Incidence of Diabetic Foot and Associated Risk Factors in Type 2 Diabetic Patients: A Five-year Observational Study / 당뇨병

BACKGROUND: The frequency of lower extremity amputation due to diabetic foot has been increasing in type 2 diabetic patients. The aim of this study was to observe the incidence, clinical aspects and associated risk factors for diabetic foot. METHODS: We evaluated the incidence of diabetic foot through a five-year observation of type 2 diabetic patients who presented to St. vincent's Hospital between January and December 2003. To identify the risk factors for diabetic foot, we evaluated mean glycosylated hemoglobin A1c (HbA1c) every six months and assessed renal function based on the existence of proteinuria and estimated glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease (MDRD) equation. Patients were also evaluated for retinopathy, peripheral neuropathy and autonomic neuropathy using Ewing's method. RESULTS: From an initial pool of 613 patients, the observational study of 508 patients (82.9%) was completed. The mean age, duration of diabetes and HbA1c were 50.3 +/- 10.6 yrs, 7.2 +/- 6.5 yrs and 8.8 +/- 2.1%, respectively. Diabetic foot occurred in 32 patients (6.3%). The incidence of diabetic foot increased when diabetic retinopathy (OR = 6.707, 2.314~19.439), peripheral neuropathy (OR = 2.949, 1.075~8.090), and autonomic neuropathy (OR = 3.967, 1.476~10.660) were present and when the MDRD GFR (OR = 5.089, 1.712~15.130) decreased. Mean HbA1c (OR = 12.013, 1.470~98.179) was found to be an independent risk factor for diabetic foot. CONCLUSION: The present study confirmed the importance of intensive glycemic control and the role of autonomic dysfunction in the development of diabetic foot. In addition, diabetic retinopathy and impaired renal function proved to be factors associated with the occurrence of diabetic foot. Therefore, intensive glycemic control, as well as periodic examination of renal function, are essential for the prevention of diabetic foot.

Cystatin C is a Valuable Marker for Predicting Future Cardiovascular Diseases in Type 2 Diabetic Patients / 당뇨병

BACKGROUND: Recent studies suggest that serum Cystatin C is both a sensitive marker for renal dysfunction and a predictive marker for cardiovascular diseases. We aimed to evaluate the association between Cystatin C and various biomarkers and to find out its utility in estimating risk for cardiovascular diseases in type 2 diabetic patients. METHODS: From June 2006 to March 2008, anthropometric measurements and biochemical studies including biomarkers for risk factors of cardiovascular diseases were done in 520 type 2 diabetic patients. A 10-year risk for coronary heart diseases and stroke was estimated using Framingham risk score and UKPDS risk engine. RESULTS: The independent variables showing statistically significant associations with Cystatin C were age (beta = 0.009, P < 0.0001), hemoglobin (beta = -0.038, P = 0.0006), serum creatinine (beta = 0.719, beta < 0.0001), uric acid (beta = 0.048, P = 0.0004), log hsCRP (beta = 0.035, P = 0.0021) and homocysteine (beta = 0.005, P = 0.0228). The levels of microalbuminuria, carotid intima-media thickness, fibrinogen and lipoprotein (a) also correlated with Cystatin C, although the significance was lost after multivariate adjustment. Calculated risk for coronary heart diseases increased in proportion to Cystatin C quartiles: 3.3 +/- 0.4, 6.2 +/- 0.6, 7.6 +/- 0.7, 8.4 +/- 0.7% from Framingham risk score (P < 0.0001); 13.1 +/- 0.9, 21.2 +/- 1.6, 26.1 +/- 1.7, 35.4 +/- 2.0% from UKPDS risk engine (P < 0.0001) (means +/- SE). CONCLUSIONS: Cystatin C is significantly correlated with various emerging biomarkers for cardiovascular diseases. It was also in accordance with the calculated risk for cardiovascular diseases. These findings verify Cystatin C as a valuable and useful marker for predicting future cardiovascular diseases in type 2 diabetic patients.

Utility of CT colonography in detecting colon polyps as a colon cancer screen / 대한내과학회지

BACKGROUND/AIMS: CT colonography is a rapid and safe imaging method for detecting polyps in the colon and rectum. We assessed the efficacy of CT colonography in colorectal polyp detection. METHODS: We prospectively studied 84 subjects (mean age 55.7+/-11.1 years; 52 men, 32 women) undergoing CT colonography followed by colonoscopy. Based on the results of CT colonography, all polyps were classified by size (any size, and those larger than 5, 7, and 10 mm) and were checked for location, morphology, and histological characteristics. We determined the sensitivity and specificity of CT colonography using colonoscopy as a reference standard with a segmental unblinding method. RESULTS: A total of 56 lesions were identified in 26 of 79 subjects undergoing both CT colonography and conventional colonoscopy. The sensitivities of CT colonography for polyps of any size, and larger than 5, 7, and 10 mm were 60.7%, 70.5%, 75.9%, and 81.8%, respectively. The per-subject sensitivities of CT colonography for the polyps of any size, and larger than 5, 7, and 10 mm, were 80.7%, 95.0%, 93.3%, and 90.9%, respectively. The per-subject specificities of CT colonography for polyps were 86.8%, 89.8%, 95.3%, and 100.0%, respectively. The sensitivities of CT colonography for flat, sessile, and pedunculated polyps were 30.8%, 85.0%, and 90.0%, respectively. CONCLUSIONS: CT colonography is a useful diagnostic method for screening colorectal neoplasias larger than 7 mm diameter, showing 75.9% sensitivity and 71.0% positive predictive value.

A Case of Gastric and Colonic Hyperplastic Polyposis Associated with Colonic Adenomas / 대한소화기내시경학회지

Hyperplastic polyps occur either sporadically or as a symptom of polyposis syndrome. When individuals exceed 50 polyps, they are diagnosed with hyperplasic polyposis. Moreover, since such cases are even more sporadic than hyperplastic polyps, the course toward this occurrence has not been properly evaluated. A change to malignancy in hyperplastic polyps is rare; however, when multiple lesions are present, the tendency increases. Colorectal polyposis syndromes with gastric polyps include familial adenomatous polyposis, Gardners syndrome, Peutz-Jeghers syndrome, juvenile polyposis and others with a non-genetic origin. Three cases of multiple colorectal hyperplastic polyposis with gastric hyperplastic polyposis have been reported worldwide; however, a case associated with multiple colonic adenomas has not yet been reported. This study reviews the existing literature and reports our recent experience of a case, in which a 53 year-old man with colorectal and gastric hyperplastic polyposis with associated multiple colonic adenomas.

The prevalence of fatigue in cancer patients at St. Vincent's hospital / 대한내과학회지

BACKGROUND: Fatigue is one of the most common problems in terminally ill cancer patients in North America and Europe. However, fatigue has been almost neglected by health care professionals and even by patients and their families in Korea. We studied the prevalence and characteristics of fatigue in cancer patients who were admitted to St. Vincent's Hospital. METHODS: Ninety-three competent patients who were admitted to the cancer or hospice ward were asked to answer whether they had fatigue or other cancer related problems on three occasions on April 4, 11 and 18, 2006. Additional demographic data were also analyzed. RESULTS: Thirty (32.3%) of the 93 patients responded that they had fatigue. The response was from 20/71 male and 10/22 female patients. The median age was 66 years (range 35-84 years). The ECOG performance status was 1, 2 and 3 in 10, 12 and 8 patients respectively. Lung cancer (21 patients) was the most common malignancy followed by gastric cancer, colon cancer and other cancers. Fourteen patients received chemotherapy, 13 patients received supportive care and 3 patients received chemoradiotherapy. Other cancer related symptoms were pain (17 patients), anorexia (16 patients), sleep disturbance (14 patients), and anxiety and depression. The severity of fatigue was grade 1, 2, 3 in 17, 6 and 7 patients respectively. Twenty-eight patients had anemia based on the WHO scale, and there was no relationship between the grade of fatigue and hemoglobin level. CONCLUSIONS: Fatigue was a frequent symptom in cancer patients (32%) and more frequent in female patients (45%). More attention needs to be paid to the significance of fatigue in cancer patients.

Bilateral Hydronephrosis Caused by Huge Uterine Myoma / 대한신장학회지

A 67-year old woman was admitted due to left femur neck fracture. Pre-operative laboratory data revealed azotemia, and kidney ultrasonogram and pelvis MRI showed bilateral hydronephrosis and huge uterine myoma. On past history, she had uterine myoma since her thirties, but she refused to undergo operation. We initially planned percutaneous nephrostomy (PCN). After stabilization of renal function, we performed subsequent total hysterectomy after insertion of catheters on both ureters, and PCN catheters were removed after confirming that both ureteral catheters worked well. During follow up period of two months after PCN, renal function was gradually improved, but it was not normalized. Size of removed myoma was about 25x15 cm, and histopathologic findings were consistent with leiomyoma. In conclusion, myoma uteri is one of the rare causes of bilateral hydronephrosis, and it may lead to irreversible damage to kidney if left untreated for a long time.

The Effect of Oriental Self-help Group Program for the Living Alone-Aged Inhabiting Rural Region

PURPOSE: The purpose of this study was to evaluate the effect of an Oriental self-help group program on living-alone elders in rural areas. METHOD: A one-group pretest-post test design was used. The subjects of the experimental group participated in the oriental self-help program, health education, feet bathing in hot water, cupping therapy, and foot-reflexology. The obtained data were analyzed using the Wilcoxon signed rank test and Pearson correlation coefficients of SPSS. RESULTS: 1) The level of blood triglyceride, SGOT and glucose decreased significantly in the experimental group compared to the control group. 2) The scores of depression and stress decreased significantly in the experimental group compared to the control group. 3) The score of Yangsaeng increased significantly in the experimental group compared to the control group. 4) Depression was higher when the score of stress was high, and the score of depression and stress were lower when the score of Yangsaeng was high. CONCLUSION: Considering the results of this research, the program is effective in improving physiological indexes partially, emotional indexes and Yangsaeng. Therefore this program can be implemented as a community-based self-help group program for living-alone elders in rural areas.

The determination of dark adaptation time using electroretinography in conscious Miniature Schnauzer dogs

The optimal dark adaptation time of electroretinograms (ERG's) performed on conscious dogs were determined using a commercially available ERG unit with a contact lens electrode and a built-in light source (LED-electrode). The ERG recordings were performed on nine healthy Miniature Schnauzer dogs. The bilateral ERG's at seven different dark adaptation times at an intensity of 2.5 cd.s/m2 was performed. Signal averaging (4 flashes of light stimuli) was adopted to reduce electrophysiologic noise. As the dark adaptation time increased, a significant increase in the mean a-wave amplitudes was observed in comparison to base-line levels up to 10 min (p > 0.05). Thereafter, no significant differences in amplitude occured over the dark adaptation time. Moreover, at this time the mean amplitude was 60.30 +/- 18.47 microV. However, no significant changes were observed for the implicit times of the a-wave. The implicit times and amplitude of the b-wave increased significantly up to 20 min of dark adaptation (p > 0.05). Beyond this time, the mean b-wave amplitudes was 132.92 +/- 17.79 microV. The results of the present study demonstrate that, the optimal dark adaptation time when performing ERG's, should be at least 20 min in conscious Miniature Schnauzer dogs.

A case of suprasellar germinoma misdiagnosed as lymphocytic hypophysitis / 대한내과학회지

We report here on a case of a 22-year-old girl with a suprasellar mass that was originally diagnosed as lymphocytic hypophysitis, but it eventually turned out to be a germinoma. She initially underwent partial tumor removal and the tissue diagnosis was suggestive of lymphocytic hypophysitis. 46 months later, she presented with a lateral visual field defect and decreased visual acuity of her right eye. The serum and cerebrospinal beta-hCG and alpha-fetoprotein levels were measured. The beta-hCG level was elevated in both, whereas the alpha-fetoprotein level was detectable in neither. The serum anti-pituitary antibody-1 level was negative. She was reoperated and the permanent section biopsies were compatible with pure germinoma. There was no evidence of meningeal metastasis on her whole spine MRI. She was treated with chemotherapy.

A Case of Gastrointestinal Stromal Tumor of the Jejunum with Obscure Gastrointestinal Hemorrhage Diagnosed by Exploratory Laparotomy / 대한소화기내시경학회지

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumor of the gastrointestinal tract, and they represent about 2% of all neoplasms of the gastrointestinal tract. GISTs primarily affect the stomach (50~60%), but they can also affect the small intestine (20~30%), large intestine (7%) and esophagus (1%). The clinical manifestations of GISTs vary according to the location and size of the mass. GISTs are generally KIT (CD117)-positive and are diagnosed by immunohistochemistry. Tumor size and mitotic activity are the best predictive prognostic features. The treatment of choice for primary GIST is complete surgical resection with a negative margin. A 78-year-old man who presented with melena and diffuse abdominal pain was admitted to our hospital. Esophagogastroduodenoscopy, colonoscopy, angiography and an RBC scan were performed but we were unable to locate the focus of the hemorrhage. A gastrointestinal stromal tumor (GIST) of the jejunum was diagnosed after laparotomy.

Two Cases of Fatal Hypoxemia after Talc Pleurodesis for Recurrent Malignant Pleural Effusion / 결핵및호흡기질환

Talc pleurodesis is a safe and effective treatment for a recurrent malignant pleural effusion. However, acute hypoxemia, pulmonary edema or acute respiratory failure can develop in a small number of patients. We report 2 patients who developed fatal hypoxemia after talc pleurodesis which was necessary the control recurrent pleural effusion. The first case was an 18-year old male diagnosed with Ewing's sarcoma with bilateral lung metastases and pleural effusion. The performance status was ECOG (Eastern Cooperative Foncology Group) grade 3. Fever along with hypoxemia and leukocytosis developed 10 hours after the second talc pleurodesis on the right side for an uncontrolled pleural effusion, The patient died from respiratory failure after 13 days. The second case was a 66-year old female diagnosed with non-small cell lung cancer with a bone metastasis. Two weeks after systemic chemotherapy, she complained of dyspnea, and a pleural effusion was observed on the right side. Her performance status was ECOG grade 3. Talc pleurodesis was performed for recurrent pleural effusion, but hypoxemia developed 6 days after pleurodesis and she died from respiratory failure 10 days after pleurodesis. In conclusion, talc pleurodesis should be performed very carefully in patients with a poor performance status, in cases with repeated pleurodesis, bilateral pleural effusion, recent chemotherapy, radiotherapy and when there are parenchymal metastatic lesions present.

Phacoemulsification and acryl foldable intraocular lens implantation in dogs: 32 cases

This study evaluated the surgical outcome and complications of phacoemulsification and the implantation of an acryl foldable intraocular lens (IOL) with a squared edge in dogs with cataracts. Thirty-two eyes from 26 dogs were examined. The mean follow up period was 75.9 days ranging from 23 to 226 days. The complications after phacoemulsification were posterior capsular opacity (PCO) around the IOL (n = 11), ocular hypertension (n = 4), focal posterior synechia (n = 4), hyphema (n = 3) and corneal ulcer (n = 2). The complications associated with the IOL were decenteration of the optic (n = 2) and ventral haptic displacement (n = 1). Most cases of PCO were found only around the margin of the IOL, and all eyes had vision during the observation period. In conclusion, the implantation of an acryl-foldable lens with a squared edge at the time of phacoemulsification is an effective method for preserving the central visual field of dogs with cataract.

Malignant ocular melanoma in a dog

A mongrel male dog of three years old was referred to the Seoul National University Veterinary Teaching Hospital following a one month history of glaucoma. On ophthalmic examination, hyphema, glaucoma, uveitis, iridal mass, and loss of vision were noted in the right eye. Ultrasonography and computed tomography revealed a mass with involvement of the entire uvea. Radiographic evaluation did not reveal any evidence of distant metastasis. The right eye was surgically removed because of the high likelihood of neoplasia. A histologic diagnosis of malignant uveal melanoma was made.

A Case of oculocutaneous albinism in a Maltese

A 4-month-old female maltese dog was admitted to Veterinary Medical Teaching Hospital of Seoul National University for evaluation of abnormal color of bilateral irises. This patient had the photophobia in the light and exhibited the complete absence of pigment resulting in white hair, pink muzzle, eyelids and foot-pads. Central zone of the irises were yellow in color influenced by tapetal reflex, and peripheral zone were pale blue. The iridal capillaries were transparented on the irises. Ophthalmoscopic examination revealed a yellow tapetal fundus but no pigment in the nontapetal fundus.
