The significance of blood pressure variation and metabolic risk factors in patients with different stages of hypertension / 고신대학교의과대학학술지

OBJECTIVES: Blood pressure variation (BPV) and metabolic syndrome is an independent risk factor for cardiovascular events. Ambulatory blood Pressure (ABP) has been shown to be more closely related to cardiovascular events in hypertensive patients than conventional office BP (OBP). Using both OBP and ABP, 4 groups of patients were identified: (1) normotensive patients (NT); (2) white coat hypertensives (WCHT); (3) masked hypertensives (MHT); and (4) sustainedhypertensives (SHT). We investigated the significance of BPV and metabolic risks of these 4 groups. METHODS: This study is a retrospective analysis of patients between January 2008 and May 2013. Echocardiography and 24 hour ABP monitoring were performed. RESULTS: BMI was significantly higher in the MHT compared with the NT. There were progressive increases in fasting glucose level from NT to WCHT, MHT, and SHT.MHT and SHT had higher 24h and nighttime BPV than NT.MHT was significantly related with BMI (r = 0.139, P = 0.010), creatinine (r = 0.144, P = 0.018), fasting glucose (r = 0.128, P = 0.046), daytime systolic BPV (r = 0.130, P = 0.017), and daytime diastolic BPV (r = 0.130, P = 0.017). Dyslipidemia (r = 0.110, P = 0.043), nighttime systolic BPV (r = 0.241, P < 0.001) and nighttime diastolic BPV (r = 0.143, P = 0.009) shown correlation with SHT. In multivariate logistic regression, MHT was independently associated with Body mass index (OR 1.086, 95% CI 1.005–1.174, P = 0.038) and creatinine (OR 1.005, 95% CI 1.001–1.010, P = 0.045). CONCLUSIONS: BPV and metabolic risk factors were found to be greater in MHT and SHT compared with NT and WCHT. This suggests that BPV and metabolic risks may contribute to the elevated cardiovascular risk observed in patients with MHT and SHT.

A Case of Persistent Apical Ballooning Complicated by Apical Thrombus in Takotsubo Cardiomyopathy of Systemic Lupus Erythematosus Patient

Takotsubo cardiomyopathy, which is also known as "transient apical ballooning", is a cardiac syndrome associated with emotional and physical stress that occurs in postmenopausal women. It may mimic acute coronary syndrome but coronary angiography reveals normal epicardial coronary arteries. The prognosis is favorable with the normalization of wall motion abnormalities within weeks. We report a case of persistent apical ballooning complicated by an apical thrombus in Takotsubo cardiomyopathy of systemic lupus erythematous patient. Takotsubo cardiomyopathy may not be always transient and left ventricular thrombus can occur in the disease course as our patient.

A Case of Superior Mesenteric Artery Syndrome Caused by Anorexia Nervosa / 대한소화기학회지

Superior mesenteric artery (SMA) syndrome is a rare disorder, characterized by compression of the third segment of the duodenum by the mesenteric artery at the level of the SMA, resulting in duodenal dilatation. Precipitating factors of the SMA syndrome include prolonged bed rest, weight loss, abdominal surgery, and increased lordosis of the spine. We report a case of SMA syndrome caused by anorexia nervosa in a 15-year-old adolescent girl. CT and an upper gastrointestinal contrast series revealed partial obstruction of the third portion of duodenum and decreased aortomesenteric distance. The patient's symptoms were successfully treated with total parental nutrition and psychiatric treatment including supportive, cognitive behavioral therapy and antidepressant medication. This case shows that SMA syndrome is an unusual gastrointestinal complication that may occur in patients with anorexia nervosa.

The Efficacy of Antiviral Agents in Patients with Hepatitis B-related Liver Cirrhosis / 고신대학교의과대학학술지

OBJECTIVES: Improvement of liver synthetic function and the incidence of complication in the patients with hepatitis B-related liver cirrhosis is important. In this study, we study whether antiviral therapy was effective in patients with hepatitis B-related liver cirrhosis. METHODS: 103 patients with hepatitis B-related liver cirrhosis treated with lamivudine 100mg daily over 6 months and followed up over 30 months. 71 patients were positive for serum HBeAg. HBeAg, HBV DNA , CBC, prothrombin time, biochemistry, ultrasonography and endoscopy were tested every 6 months. RESULTS: The medians of ALT, albumin improved after 6 months and then aggravated after 18 months, but they didn't aggravated at 30 months compared with initial test. The median of Child-turcotte-pugh (CTP) score imporved after 6 months and then aggravated after 12 months, but they didn't aggravated at 30 months compared with initial test. The CTP score improved (2 point reduction) in 29 patients. The finding of ultrasonography didn't aggravaed (improved or didn't changed) in 58 patients. The 5 year incidence rate of hepatocelluar carcinoma was 8.3%. CONCLUSIONS: The antiviral therapy in patients with hepatitis B-related liver cirrhosis is improved CTP score and biochmical data. The improvement is more useful in decompensated cirrhosis the compensated cirrhosis. The incidence of hepatocellular carcinoma decreases than other studies. Therefore, the antiviral medication in patients with hepatitis B-related liver cirrhosis is helpful to consider more aggressively.

A Case of Mediastinal Ectopic Thyroid Tissue Diagnosed by Endobronchial Ultrasound Guided Transbronchial Needle Aspiration / 고신대학교의과대학학술지

A 77-year old woman was referred to hospital with dyspnea and chest dull pain for 5 months. The chest radiograph showed a mass located in the mediastinum. Trachea was deviated to right side. Chest computed tomography showed an enhancing large mass at the middle mediastinum. Endobronchial ultrasonography showed hyperechoic mediastinal mass. We performed endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA). Histologic finding was thyroid tissue with a benign looking papilla. Ectopic thyroid is an uncommon embryological aberration characterized by the presence of thyroid tissue in a site other than in its usual pretracheal region. It occurs along the path of descent of the developing thyroid primodium from the foramen cecum. It is extremely rare for mediastinal ectopic thyroid tissue diagnosised by EBUS-TBNA, so we report here on a case of mediastinal ectopic thyroid and we review the relevant medical literature.

A Case of Acute Generalized Exanthematous Pustulosis with Patterns of Septic Shock / 대한내과학회지

Acute generalized exanthematous pustulosis (AGEP) is a rare disease characterized by multiple acute, small, non-follicular, sterile pustules on an erythematous background, usually accompanied by fever and leukocytosis. AGEP is attributed to systemic drugs, mainly beta-lactam and macrolide antimicrobials, in more than 90% of cases. Systemic contact dermatitis is not rare after ingesting lacquer broth, but few reported cases of AGEP have occurred after the ingestion of lacquer chicken broth without a past history of drugs, viral infection, or contact allergy to mercury. Here, we report a rare case of AGEP with a pattern of septic shock induced by the intake of lacquer chicken in a 40-year-old male patient. He developed a generalized pustular lesion with high fever and hypotension. Histologic examination showed subcorneal neutrophilic pustules, papillary dermal edema, and lymphohistiocytic perivascular infiltrates with some eosinophils and neutrophils. The patient was treated with empirical antibiotics and systemic steroids, and the pustular lesions improved 2 weeks later without recurrence.
