The recent advent of "-omics" technologies have heralded a new era of personalized medicine. Personalized medicine is referred to as the ability to segment heterogeneous subsets of patients whose response to a therapeutic intervention within each subset is homogeneous. This new paradigm in healthcare is beginning to affect both research and clinical practice. The key to success in personalized medicine is to uncover molecular biomarkers that drive individual variability in clinical outcomes or drug responses. In this review, we begin with an overview of personalized medicine in breast cancer and illustrate the most encountered statistical approaches in the recent literature tailored for uncovering gene signatures.

V. parahaemolyticus was isolated from blood culture of a 34-year old female patient with HCV viral hepatitis and liver cirrhosis. V. parahaemolyticus is one of the frequent causative agents of gastrointestinal infection, but rarely causes septicemia. This case is thought to be the 3rd report of V. parahaemolyticus septicemia in Korea.

Cardiovascular disease is the most important cause of unexpected sudden death. Although ischemic heart disease by coronary atherosclerosis is the most common cause of sudden cardiac death, other diseases such as cardiomyopathy, congenital heart disease, valvular heart disease and rarely myocarditis can produce sudden cardiac death. Myocarditis is an inflammatory process of the myocardium characterized by an interstitial inflammatory infiltrate and an injury to myocytes adjacent to the inflammatory cells. The clinical expression of myocarditis ranges from the asymptomatic state to fulminant fatal congestive heart failure. Because myocardial involvement is subclinical in most acute infectious disease, the majority of patients have no specific complaints referable to the cardiovascular system. It is possible that it causes a medicolegal problems in case of sudden death. Therefore, author reviewed the clinical and pathological findings of 18 myocarditis autopsy cases. The victims 'age was varied 4-month-59-year olds. 5 (28%) were male and 13 (72%) were female. 15 cases received medical treatment due to clinical symptoms(URI symptoms: 2 cases, tonsillitis and tonsillar abcess: 3 cases, GI symptoms: 5 cases, URI & GI symptoms: 3 cases, pneumonia: 1 case, operation due to ovarian tumor: 1 case) and were associated with medicolegal problem. By the results of this study, important gross findings were pericardial effusions, characteristic cardiomegaly, and pulmonary edema.

Wernicke's encephalopathy is a reversible but potentially critical disease caused by thiamine deficiency. Most patients complain of symptoms such as ophthalmoplegia, ataxia and confusion. Heavy alcohol drinking is commonly associated with the disease, but other clinical conditions also can provoke it. In pregnant women, hyperemesis gravidarum can lead to the depletion of body thiamine due to poor oral intake and a high metabolic demand. We report a case of Wernicke's encephalopathy following hyperemesis gravidarum in a 36-year-old female at 20 weeks of pregnancy, who visited our hospital because of shock with vaginal bleeding. This case suggests that although the initial presentation may include atypical symptoms (e.g., shock or bleeding), Wernicke's encephalopathy should be considered, and thiamine replacement should be performed in pregnant women with neurologic symptoms and poor oral intake.

Splenic metastasis from solid cancer is a rare clinical event. Especially splenic metastasis from the lung is very rare. Most spleen metastases are found at autopsy and are part of a widely spread disease. Solitary splenic metastasis in the abscence of other metastases is extremely rare. The authors report the case of a 54-year-old man in whom the only discover distant metastasis from lung cancer was a splenic mass. The splenic lesion was detected after the resection of the primary lung lesion. The time from diagnosis to the development of splenic metastasis was 25 months. The rarity of a solitary spleen metastasis from lung cancer and the treatment modalities are discussed. When solitary spleen metastasis is suspected in a clinical setting, aggressive treatment is indicated, a splenectomy followed by combined modality treatment to prevent the spread and aggravation of the disease.

Journal of Korean Neurosurgical Society 2012;52(1):27-31
OBJECTIVE: Although hydroxyapatite (HA) spacer has been used for laminoplasty, there have been no reports on factors associated with fusion and on the effects of HA shape. METHODS: During January 2004 and January 2010, 45 patients with compressive cervical myelopathy underwent midline-splitting open door laminoplasty with winged (33 cases) and wingless (12 cases) HAs by a single surgeon. Minimal and mean follow up times were 12 and 28.1 months, respectively. Japanese Orthopedic Association (JOA) score was used for clinical outcome measurement. Cervical X-rays were taken preoperatively, immediately post-operatively, and after 3, 6, and 12 months and computed tomography scans were performed preoperatively, immediately post-operatively and after 12 months. Cervical lordosis, canal dimension, fusion between lamina and HA, and affecting factors of fusion were analyzed. RESULTS: All surgeries were performed on 142 levels, 99 in the winged and 43 in the wingless HA groups. JOA scores of the winged group changed from 10.4+/-2.94 to 13.3+/-2.35 and scores of the wingless group changed from 10.8+/-2.87 to 13.8+/-3.05. There was no significant difference on lordotic and canal dimensional change between two groups. Post-operative 12 month fusion rate between lamina and HA was significantly lower in the winged group (18.2 vs. 48.8% p=0.001). Multivariate analysis showed that ossification of the posterior longitudinal ligament, male gender, and wingless type HA were significantly associated with fusion. CONCLUSION: Clinical outcome was similar in patients receiving winged and wingless HA, but the wingless type was associated with a higher rate of fusion between HA and lamina at 12 months post-operatively.

The task of chromosome analysis is the classification of human chromosomes. The feature parameter of chromosome is very important information for chromosome analysis. The special preprocessing algorithm is required to extracting them. In this paper, we performed quantitative analysis for preprocessing algorithm of observation of chromosomal aberrations. Two algorithms is used MAT and reconstruction. The morphological feature parameters were centromeric index(C.I.), relative length ratio(R.L.), relative area ratio(R.A.) and chromosome length(C.L.), and the density and width profiles. The reconstruction of chromosome images by this reconstruction algorithm was appeared as effective algorithms to observe and extract chromosome parameter.
