RESUMO
Neurocysticercosis is the most common parasitic infection of the nervous system. However, the improvement in public health made the prevalence of neurocysticercosis low. Neurocysticercosis may have symptoms such as seizures, headache, and hydrocephalus, and calcified neurocysticercosis is generally known to be asymptomatic and inert. Also, status epilepticus associated with neurocysticercosis has been rarely reported. Therefore, we report a case of focal status epilepticus caused by calcified neurocysticercosis that invaded the subarachnoid space, which is uncommon pathophysiology of neurocysticercosis.
RESUMO
BACKGROUND/OBJECTIVES@#Chronic or intermittent hyperglycemia is associated with the development of diabetic complications. Oxidative stress and inflammation can be altered by hyperglycemia in diverse tissues, including kidneys and eyes, and play a pivotal role in diabetic complications. Our previous studies showed that the water-insoluble 5,7-dihydroxyflvone chrysin effectively combats diabetic damages incurred in diabetic kidneys and retinas. The current study employed the newly-synthesized 5.7-di-O-acetylchrysin, having higher solubility than chrysin, to compare the effects on diabetes-associated renal fibrosis and abnormal retinal neovascularization.MATERIALS/METHODS: In the in vivo study, db/db mice as animal models of type 2 diabetes were orally administrated 10 mg/kg BW diacetylchrysin, daily for 10 weeks. @*RESULTS@#Unlike chrysin, oral administration of 10 mg/kg diacetylchrysin did not lower the blood glucose level and 24 h urine volume in db/db mice. Nevertheless, the urinary albumin excretion was markedly reduced. The administration of diacetylchrysin also diminished the deposition of collagen fibers in diabetic glomeruli and tubules by suppressing the induction of connective tissue growth factor and collagen IV in diabetic kidneys. Supplying diacetylchrysin enhanced the membrane type-1 matrix metalloproteinase (MMP) expression reduced in diabetic kidneys, while the tissue inhibitor of MMP-2 induction was attenuated in diacetylchrysin-challenged diabetic kidneys. In addition, supplementing diacetylchrysin to diabetic mice ameliorated renal injury due to glomerulosclerosis and tubular interstitial fibrosis. Furthermore, the reduced retinal inductions of Zonula occludens-1 and vascular endothelial cadherin in db/db mice were elevated in the retinal tissues of diacetylchrysintreated animals. Oral administration of diacetylchrysin curtailed the induction of vascular endothelial growth factor (VEGF) and VEGF receptor 2 in db/db mice, ultimately retarding diabetes-associated retinal neovascularization. Additionally, the retinal formation of acellular capillaries with leaky vessels was reduced in diacetylchrysin-treated db/db mice. @*CONCLUSION@#Diacetylchrysin may act as a potent pro-health agent for treating renal fibrosisassociated diabetic nephropathy and retinal neovascularization-associated diabetic retinopathy.
RESUMO
Objectives@#It is important that inflammatory bowel disease (IBD) patients adhere to their prescribed medication regimens to avoid the repeat exacerbations, complications, or surgeries associated with this disorder. However, there are few studies on medication adherence in patients with IBD, especially in Asian populations. So, we analyzed the factors associated with medication adherence in Korean IBD patients. @*Methods@#Patients who had been diagnosed with Crohn’s disease (CD) or ulcerative colitis (UC) more than 6 months previously and receiving oral medications for IBD were enrolled. Medication adherence was measured using the Medical Adherence Reporting Scale (MARS-5), a self-reported medication adherence measurement tool. @*Results@#Among 207 patients in the final study population, 125 (60.4%) had CD and 134 (64.7%) were men. The mean age was 39.63 years (SD, 13.16 years) and the mean disease duration was 10.09 years (SD, 6.33 years). The mean medication adherence score was 22.46 (SD, 2.86) out of 25, and 181 (87.4%) patients had score of 20 or higher.In multiple linear regression analysis, self-efficacy (β=0.341, P<0.001) and ≥3 dosing per day (β=–0.192 P=0.016) were revealed to be significant factors associated with medication adherence. Additionally, there was a positive correlation between self-efficacy and medication adherence (r=0.312, P<0.001). However, disease related knowledge, depression, and anxiety were not significantly associated with medication adherence. @*Conclusion@#To improve medication adherence among patients with IBD, a reduction in the number of doses per day and an improved self-efficacy will be helpful.
RESUMO
Background@#Myokymia consists of involuntary, fine, continuous contraction that spread across the affected striated muscle. Eyelid myokymia, unlike other dystonic facial contracture such as blepharospasm and hemifacial spasm, is assumed to be a benign, self-limited disorder. Eyelid myokymia is associated with stress, fatigue, excercise, and exccessive caffeine use. The pathophysiology is not well understood, but some drugs or brain structural lesions are the cause of the eyelid myokymia. Especially in Korea hypomagnesemia is generally known the main cause of eyelid myokymia, however there are no evidences so far. This study investigated the relation between eyelid myokymia and serum magnesium level. @*Methods@#We performed a cross sectional study on 72 patients with myokymia and 197 controls. We investigated fatigue, sleep quality, alcohol, smoking, caffeine use, and exercise datas by interview. We analyzed laboratory datas including magnesium, calcium, phosphate, thyroid hormone in serum. @*Results@#Demographic characteristics between the patients with myokymia and controls showed no significant differences in age, gender, smoking, and alcohol history. Fatigue and poor sleep quality were significantly higher in the myokymia group than control group. However, any laboratory results including magnesium showed no significant differences between two groups. @*Conclusions@#These data suggested that the eyelid myokymia is not related to the serum magnesium level as well as calcium and phosphate. Only fatigue and sleep quality were shown the relationship with eyelid myokymia.
RESUMO
Background@#It is well known that the prevalence of obesity in Korea is increasing over time, however it is not known how the trends among occupational groups and sex differ in such increasing trends. This study was designed to provide recent trends of obesity among workers in Korea and to identify whether there were differences among occupational groups. @*Methods@#We used data from the Korean National Health and Nutrition Examination Survey, Phases I to VI (1998–2015), to analyze trends in the prevalence of obesity in adult Korean workers. Obesity was defined as a body mass index of 25 kg/m2 or higher. Occupations were classified into 3 groups: (a) nonmanual workers, (b) service/sales workers, and (c) manual workers. @*Results@#During the period of the Korean National Health and Nutrition Examination Survey Phases I to VI, the prevalence of obesity in male workers increased in all occupations (31.1% to 39.5% in manual workers, 32.3% to 38.2% in service/sales workers, and 25.3% to 39.7% in manual workers). However, female workers did not show any particular tendency toward obesity, except for a significant decrease in the prevalence rate in service/sales workers (30.8% to 23.9%, p for trend = 0.0048). @*Conclusion@#The trends of obesity prevalence by sex and occupation were different. For male manual workers, the prevalence rate increased steadily during the data period, while it decreased steadily in female sales/service workers.
RESUMO
BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the efficacy of revision cochlear implant (CI) surgery for better speech comprehension targeting patients with low satisfaction after first CI surgery. SUBJECTS AND METHODS: Eight patients who could not upgrade speech processors because of an too early CI model and who wanted to change the whole system were included. After revision CI surgery, we compared speech comprehension before and after revision CI surgery. Categoies of Auditory Performance (CAP) score, vowel and consonant confusion test, Ling 6 sounds, word and sentence identification test were done. RESULTS: The interval between surgeries ranged from eight years to 19 years. Same manufacturer’s latest product was used for revision surgery in six cases of eight cases. Full insertion of electrode was possible in most of cases (seven of eight). CAP score (p-value=0.01), vowel confusion test (p-value=0.041), one syllable word identification test (p-value=0.026), two syllable identification test (p-value=0.028), sentence identification test (pvalue=0.028) had significant improvement. Consonant confusion test (p-value=0.063), Ling 6 sound test (p-value=0.066) had improvement but it is not significant. CONCLUSIONS: Although there are some limitations of our study design, we could identify the effect of revision (upgrade) CI surgery indirectly. So we concluded that if patient complain low functional gain or low satisfaction after first CI surgery, revision (device upgrade) CI surgery is meaningful even if there is no device failure.

BACKGROUND/OBJECTIVE: There is intense interest in soy isoflavone as a hormone replacement therapy for the prevention of postmenopausal osteoporosis. A new kind of isoflavone-enriched whole soy milk powder (I-WSM) containing more isoflavones than conventional whole soy milk powder was recently developed. The aim of this study was to investigate the effects of I-WSM on bone metabolism in ovariectomized mice. MATERIALS/METHODS: Sixty female ICR mice individually underwent ovariectomy (OVX) or a sham operation, and were randomized into six groups of 10 animals each as follows: Sham, OVX, OVX with 2% I-WSM diet, OVX with 10% I-WSM diet, OVX with 20% I-WSM diet, and OVX with 20% WSM diet. After an 8-week treatment period, bone mineral density (BMD), calcium, alkaline phosphatase (ALP), tartrate-resistant acid phosphatase (TRAP) 5b, osteocalcin (OC), procollagen 1 N-terminal propeptide (P1NP), and osteoprotegenin (OPG) were analyzed. RESULTS: BMD was significantly lower in the OVX group compared to the Sham group but was significantly higher in OVX + 10% I-WSM and OVX + 20% I-WSM groups compared to the OVX group (P < 0.05). Serum calcium concentration significantly increased in the OVX + 10% and 20% I-WSM groups. Serum ALP levels were significantly lower in the OVX + 10% and 20% I-WSM groups compared to the other experimental groups (P < 0.05). OC was significantly reduced in the OVX group compared to the Sham group (P < 0.05), but a dose-dependent increase was observed in the OVX groups supplemented with I-WSM. P1NP and OPG levels were significantly reduced, while TRAP 5b level was significantly elevated in the OVX group compared with the Sham group, which was not affected by I-WSM (P < 0.05). CONCLUSIONS: This study suggests that I-WSM supplementation in OVX mice has the effect of preventing BMD reduction and promoting bone formation. Therefore, I-WSM can be used as an effective alternative to postmenopausal osteoporosis prevention.

PURPOSE: Platycodon grandiflorum (a domestic diploid variety, DV-PG) has been used as a food and component of various traditional oriental medicines. Although DV-PG is known to have an anti-allergic effect, little is known about the beneficial health effects of the tetraploid ‘Etteum’ variety in the Platycodon grandiflorum (TV-PG), which is a recently developed variety. In this study, we investigated the effect of TV-PG on the rat basophilic leukemia mast cell (RBL-2H3)-mediated allergic response. METHODS: To examine the effects of TV-PG on the allergic response, RBL-2H3 cells were sensitized with dinitropheny (DNP)-immunoglobin E, treated with various concentrations of TV-PG, and challenged with DNP-human serum albumin. We estimated cell granulation by measuring the release of β-hexosaminidase and production of inflammatory mediators by ELISA. RESULTS: TV-PG had no effect on the proliferation or cytotoxicity of RBL-2H3 cells within the concentration range of 0 to 200 µg/mL. TV-PG inhibited degranulation of RBL-2H3 cells by antigen stimulation in a dose-dependent manner. TV-PG also suppressed the production of inflammatory cytokines and mediators such as interleukin-4, tumor necrosis factor-α, prostagladin E2, and leukotriene B4 in RBL-2H3 cells by antigen stimulation. CONCLUSION: These results indicate that TV-PG exhibits anti-allergic activity via inhibition of degranulation as well as suppression of inflammatory mediators and cytokine release. These findings suggest that TV-PG may have potential as a preventive and therapeutic agent for the treatment of various allergic diseases.

Multiple primary malignant neoplasms indicate an occurrence of two or more malignancies in a patient, and double primary cancers are the most common type. When the second primary cancer occurs simultaneously or within 6 months after the first primary cancer is diagnosed, it is called synchronous carcinoma. If the second primary cancer occurs after 6 months, it is defined as metachronous carcinoma. Recently, we experienced a patient who was diagnosed as double primary cancer in the nasopharynx and nasal cavity. The tumors occurred simultaneously and histopathological examinations revealed nasopharyngeal nonkeratinizing carcinoma in the right nasopharynx and extranodal NK/T-cell lymphoma in the left nasal cavity (inferior turbinate). In situ hybridization showed positivity for Epstein-Barr virus, which encoded early RNA in the neoplastic cells of both specimens. We present this rare disease entity with a review of the relevant literature and a survey of the clinical characteristics.

BACKGROUND AND OBJECTIVES: This study aims to verify the usefulness of Centor scores to diagnose the Group A Streptococcal pharyngitis. SUBJECTS AND METHOD: The subjects of this study were 379 patients who had been examined by the rapid antigen detection test (RADT) for Group A Streptococcus. We analyzed their medical records and laboratory test results retrospectively and compared the results of Centor symptom scores with those of RADT. Then we analyzed the association of RADT, the Centor score and the laboratory test results statistically. RESULTS: There were no correlation between the RADT results and fever, cough, tonsillar enlargement, nasal symptoms, myalgia or chilling (p>0.05). In the RADT positive group, there were more patients with tonsillar exudate, neck lymph node enlargement, tenderness and pharyngeal abscess formation significantly (p<0.05). The Centor score and C-reactive protein were significantly higher in the RADT positive group (p<0.05). CONCLUSION: The results of this study suggest that Centor symptom scores can be used to determine which antibiotics to use. The Centor score system can help reduce medical costs and detect the problematic Group A Streptococcal pharyngitis.

RESUMO
BACKGROUND AND OBJECTIVES: Altough tonsillectomy is one of the most common otolaryngological procedures, a highly reliable and effective method for reducing postoperative pain has yet to be identified. This study evaluated the efficacy of a non-steroidal anti-inflammatory drug (NSAID) mouthwash on postoperative pain in tonsillectomy patients. SUBJECTS AND METHOD: A total of 64 patients who underwent tonsillectomy were randomly assigned to one of two groups (32 patients each). One group received the NSAID mouthwash and the other a distilled water mouthwash. Postoperative pain in the two groups was compared by assessing pain severity 1-9 days postoperatively using a visual analog scale. RESULTS: Compared to the distilled water mouthwash group, patients using the NSAID mouthwash showed a statistically significant decrease in postoperative pain over the first 9 postoperative days. CONCLUSION: A NSAID mouthwash may be a simple and effective method for controlling post-tonsillectomy pain when administered in conjunction with routine medications.

Drug-induced immune hemolytic anemia (DIIHA) is a rare side effect of drugs. DIIHA may cause a systemic inflammatory response that results in acute multi-organ failure and death. Ceftizoxime belongs to the class of third generation cephalosporins, which are the most common drugs associated with DIIHA. Herein, we present a case of a 66-year-old man who developed fatal DIIHA after receiving a second dose of ceftizoxime. He was admitted to receive photodynamic therapy. He had a history of a single parenteral dose of ceftizoxime 3 months prior to admission. On the day of the procedure — shortly after the infusion of ceftizoxime — the patient's mental status was altered. The blood test results revealed hemolysis. Oliguric acute kidney injury developed, and continuous renal replacement therapy had to be applied. On the suspicion of DIIHA, the patient underwent plasmapheresis. Diagnosis was confirmed by a detection of drug-dependent antibody with immune complex formation. Although his hemolysis improved, his liver failure did not improve. He was eventually discharged to palliative care, and subsequently died.

Klinefelter's syndrome is the most common congenital abnormality that causes primary hypogonadism. It is associated with diseases that predominantly affect women, such as systemic lupus erythematosus (SLE), and it can sometimes cause veno-occlusive disease. We experienced a case of Budd-Chiari syndrome (BCS) in a 33-year-old man with Klinefelter's syndrome presented with hematemesis and edema in both lower extremities. The clinical and laboratory findings were compatible with SLE, antiphospholipid syndrome, and BCS. To the best of our knowledge, this is the first case report to describe a simultaneous presentation of these four clinical syndromes in a single patient.

BACKGROUND AND OBJECTIVES: Pediatric obstructive sleep apnea (OSA) can have an effect on the quality of life (QOL) such as behavior, school performance, emotional distress and daytime function. We aim to verify changes in sleep disordered breathing based on polysomnographic findings and disease specific health related QOL before and after adenotonsillectomy in Korean children with OSA. SUBJECTS AND METHOD: A total 20 children aged 3 through 13 years old (mean age=6.7 years old and male/female=14/6) with OSA were included. We evaluated respiratory disturbances in patients using the standard polysomnography and the OSA-specific health related QOL based on Korean Obstructive Sleep Apnea-18 Survey (KOSA-18). RESULTS: There were significant improvements in apnea-hypopnea index (from 9.4±7.4 to 1.1±0.8 events/hour, p<0.001) and total score of KOSA-18 (71.3±26.0 to 33.6±10.7, p<0.001) after adenotonsillectomy. CONCLUSION: Sleep disordered breathing and QOL improve significantly after adenotonsillectomy in Korean OSA children.

OBJECTIVES: This study assessed the regenerative efficacy of basic fibroblast growth factor (FGF) in a rabbit model of chronic vocal fold scarring and then confirmed its utility and safety in a prospective trial of patients with this condition. METHODS: FGF was injected three times, at 1-week intervals, into a chronic vocal fold scar created in a rabbit model. After 1 month, mRNA level of procollagen I, hyaluronic acid synthetase 2 (HAS 2), and matrix metalloproteinase 2 (MMP 2) were analyzed by real-time polymerase chain reaction. The relative densities of hyaluronic acid (HA) and collagen were examined 3 months post-injection. From April 2012 to September 2014, a prospective clinical trial was conducted at a tertiary hospital in Korea. FGF was injected into the mild vocal fold scar of 17 consecutive patients with a small glottic gap. The patients underwent perceptual, stroboscopic, acoustic aerodynamic test, and Voice Handicap Index (VHI) survey prior to and 3, 6, and 12 months after FGF injection. RESULTS: FGF injection of the vocal fold scar decreased the density of collagen and increased mRNA level of HAS 2 and MMP 2 expression significantly compared to the control group injected with phosphate buffered solution in a rabbit model (P < 0.05). In the clinical trial, significant improvements in the majority of the subjective and objective voice parameters were registered 3 months after FGF injection and were maintained at 12 months. Complications associated with the FGF injections, such as granuloma, were not observed during the follow-up period. CONCLUSION: Based on the animal model and the prospective clinical trial, vocal fold injections of FGF in patients with mild chronic vocal fold scarring can significantly improve voice quality for as long as 1 year and without side effects. Our results recommend the use of FGF vocal fold injection as an alternative treatment modality for mild chronic vocal fold scarring.

BACKGROUND AND OBJECTIVES: Positional therapy is a therapeutic method for obstructive sleep apnea (OSA). However, little is known about the effectiveness of positional OSA treatment based on meta-analysis. Therefore, we undertook a review and meta-analysis of studies to assess the effect of positional therapy on OSA. SUBJECTS AND METHOD: We searched PubMed (Medline), OVID Medline, EMBASE, Cochrane Library, SCOPUS, KoreaMed, MedRIC, and KSI KISS using the key words “obstructive sleep apnea” and “positional therapy”. To estimate the effect of positional OSA therapy, we analyzed the ratio of means (ROM) for pre- and post-treatment polysomnographic data including apnea-hypopnea index (AHI), lowest oxygen saturation, arousal index, and sleep efficiency. RESULTS: Finally, twenty two studies from 21 papers were included in the meta-analysis. Positional therapy significantly decreased AHI by 54.1% [ROM, 0.459; 95% confidence interval (CI), 0.394 to 0.534] and increased lowest oxygen saturation by 3.3% (ROM, 1.033; 95% CI, 1.020 to 1.046). However, positional therapy did not significantly change arousal index (ROM, 0.846; 95% CI, 0.662 to 1.081) or sleep efficiency (ROM, 1.008; 95% CI, 0.990 to 1.027). CONCLUSION: Positional therapy significantly improves respiratory parameters including AHI and lowest oxygen saturation in patients with OSA.

Primaquine is often administered for the hypnozoite stage of Plasmodium vivax and Plasmodium ovale. Primaquine (with clindamycin) is also an alternative drug for treatment of pneumocystis pneumonia when trimethoprim/sulfamethoxazole cannot be used. Primaquine may cause methemoglobinemia, an altered state of hemoglobin in which the ferrous state of heme is oxidized to the ferric state. We report a case of methemoglobinemia caused by a standard dose of primaquine plus clindamycin in a 27-year-old female recipient of a kidney transplant who was diagnosed with pneumocystis pneumonia.
