  • Objective: To study the relationship between clinical pathologic characteristics, treatment modalities and prognostic factors in HER-2 (Human Epidermal growth factor Receptor-2) overexpressed breast carcinoma. Materials and Methods: Major clinico-pathological factors including therapeutic modalities and survival status of 371 breast cancer patients with HER2 over-expression, teated at Yantai Yuhuangding Hospital from March of 2002 to December of 2010 were retrospectively studied, with special attention focused on survival-related factors. Results: The median age of the total 371 patients in this study was 48 years at time of diagnosis, among which, the leading pathological type was infiltrating ductal carcinoma (92.5%); 62.8% presented with a primary tomor larger than 2 cm in diameter at diagnosis, 51.0% had axillary lymph node (ALN) metastases; ER (Estrogen receptor)/PR (Progesterone receptor) double negative occured in 52.8% of cases, and PCNA (proliferation cell nuclear antigen) (+++) was found in 55.1%. HER-2 overexpressed patients were usually in advanced stage when the diagnosis was made (72.8% at stages IIA~IIIC). The prognosis and survival were assessed in 259 patients with complete follow-up data. 5-year DFS (disease-free survival) and OS (overall survival) rate was 68.0% and 78.0% respectively. Univariate analysis revealed that age, tumor size, ALN metastases, LVSI (lymph-vascular space involvement), PCNA status, hormonal therapy, chemotherapy cycles, and HER-2 overexpression, correlated closely with the prognosis. ALN metastases, LVSI, PCNA status and chemotherapy cycles were independent predictors of survival. Conclusions: HER-2 overexpressed breast cancer has special clinical and pathological characteristics, with advanced clinical stages and high rate of ER/PR double negative. Lymph node metastases, LVSI, PCNA and chemotherapy cycles are independent predictors of prognosis.

  • Though modern medicine has taken rapid strides, varieties of intractable maladies and diseases go on increasing more and more. And so medical technologies and academic achievements related to diagnoses and prognoses are being carried on. As the progress of genetics, all sorts of diseases have proved to be hereditary. This makes efficient use of the prevention of diseases. According to Sasang-Constitution medicine, each person inherently possesses a unique constitution different from that of any other person. The shapes and sizes, temperaments and characters of people have enormous variations that must affect our health and happiness. Without understanding our particular constitution, we must fall into poor health and disease. The food and exercise that are good for one person's constitution may not be good for another. No standardized medicine can adequately deal with our individual variations. Only a system that can discern our different constitutional types has this capacity. This paper is to study Life-Regulating Science that has taken firm root in our culture from time immemorial, so that I suggest the methods of diagnoses and prognoses by using Life-Regulating Science. In the medical texts, psychological imbalances of Eum-Yang and Five Phases generate all kinds of diseases. Accordingly visceral manifestation and diseases as a future possibility may be known by the Four Pillars.

  • Polymorphous low-grade adenocarcinoma (PLGA) is a neoplasm that is regarded as the second most common malignant salivary gland tumor after mucoepidermoid carcinoma. After the diagnosis of PLGA it is important to make a treatment decision and consider the prognosis. A histopathologic examination is necessary for diagnosis. Treatment is primarily surgical excision and long-term follow up is essential to evaluate local recurrences. This report describes 2 cases of PLGA located in the soft palate without any evidence of metastasis. The first case was PLGA with bony infiltration and an irregular margin lesion. The second case was PLGA localized in palatal soft tissue. We present diagnoses, histopathologic features, treatments and prognosis of PLGA.

  • Background: New tumour biomarkers are being intensely investigated for malignant mesothelioma (MM). Fibulin-3 is produced in MM but its role remains uncertain. The aim of this study was to evaluate the validity of measuring serum fibulin-3 in the diagnosis and prognosis of MM. Materials and Methods: This prospective study was performed on 43 patients and 40 healthy controls who were admitted to our hospital between January 2012 and January 2014. Data from MM patients, including demographic and clinical features, routine laboratory data, levels of serum fibulin-3, and treatment outcomes were defined as potential prognostic factors. The receiver operating characteristic (ROC) curve for fibulin-3 was used to detect the cut-off value with highest sensitivity and specificity. Univariate survival analysis was performed using the Kaplan-Meier method in patients with MM. Afterwards, the possible factors identified with univariate analyses were entered into the cox regression analysis. Results: Our results revealed that patients with MM had significantly higher serum levels of fibulin-3 than controls. The results showed that the best cut-off point was 36.6 ng/ml with an AUC (area under the curve)=0.976, sensitivity=93.0% and specificity=90.0. In our study, the initial significant poor prognostic factors were advanced stage, high white blood cell count, high platelet count, high C-reactive protein (p<0.05 for each variable). Later, according to multivariate analysis the results showed only advanced stage as significant parameter (p=0.040). Conclusions: We determined that real use for serum fibulin-3 was not for prognosis but for diagnosis in MM. Also advanced stage was associated with poor MM prognosis.

  • Inherited metabolic disease is rare disorders that show symptoms mainly in pediatric age and early treatment is important for preventing complications of the disease. Recent development in molecular and biochemical techniques help clinicians with proper diagnosis of patients, however, many of the disease still remain lack of effective therapeutic strategies. Better understanding on biochemical and molecular basis of pathogenesis of the disease combined with advanced medical care would provide new sight on the disease that can also improve the quality of life and long-term prognosis of patients. Traditionally, there are several modalities in the treatment of metabolic diseases depend on the biochemical basis of the disease such as diet restriction, removing or blocking the production of toxic metabolites, and stimulating residual enzyme activity. The inherited metabolic disease is not familiar for many clinicians because the diagnosis is troublesome, treatment is complicated and prognosis may not as good as expected in other diseases. Recently, new therapeutic regimens have been introduced that can significantly improve the medical care of patients with metabolic disease. Enzyme replacement therapy has showed promising efficacy for lysosomal storage disease, bone marrow transplantation is effective in some disease and gene therapy has been trying for different diseases. The new trials for treatment of the disease will give us promising insight on the disease and most clinicians should have more interest in medical progress of the metabolic disease.

  • In case of missing of permanent teeth by trauma or innate defect, the decision of treatment modalities and application timing have an important effect on the prognosis of oral rehabilitation. In this case report, interdisciplinary approach between the orthodontic and prosthodontic treatment, the way to re-establish the collapsed occlusal vertical dimension, and implant prosthetic considerations will be discussed. Proper diagnosis on teeth and craniofacial skeleton was made prior to treatment and provisional restorations were used in regard of growth patterns of the patient. Finally, the edentulous areas were restored with fixed implant prostheses. Diagnosis, treatment rationale and prognosis will be discussed thoroughly.

  • Objective : The aim of this study is to analyze the clinical symptoms, radiological changes, interval from first operation to symptom recurrence and to propose the proper treatment method for re-operated patients following chronic subdural hematoma surgery. Methods : Between January 1992 and April 2003, 18 of 138patients of chronic subdural hematoma repeatedly underwent surgical treatment. The symptoms, mental status by Bender grade, radiological hematoma size and midline shifting, interval from symptom onset to diagnosis, surgical method and prognosis by Glasgow outcome scale[GOS] between the first attack and the recurrence were compared. Results : The symptoms at the time of recurrence were nearly the same as with the first attack, but two patients[2/18, 11.1%] showed a more declined mentality. In addition, the recurred hematoma sizes were the same or large than those previously found. Many patients were recurred within two weeks[13/18, 72.2%]. Most patients were operated on using the previous burr hole, with the exception of one patient who recurred at a different site. All patients had a good prognosis more than GOS 4 [GOS 4:4, GOS 5:12], but two died due to extracranial complication and infection. Conclusion : These results suggest that the early diagnosis and treatment are important, mostly recurred same symptoms within two weeks. Re-operation using the previous burr hole site is a good method.

  • As wind power has increased steadily, the importance of a condition monitoring system is being emphasized to maximize the availability and reliability of a wind turbine. To develop the advanced algorithms for fault detection and lifespan estimation, a wind turbine simulator is essential for verification of the proposed algorithms before applying them to a condition diagnosis & integrity prognosis system. The developed new-type simulator in this paper includes blades and various sensors as well as a motor, a gearbox and a generator of which the existing simulators generally consist. It also has similarity with a 3MW class wind turbine and can be used to acquire operational data from various operation conditions. This paper presents a design method of control logic for the wind turbine simulator, which gives a wind generation method and similar dynamic characteristics with the 3MW wind turbine. Finally, the proposed control logic is verified through experiments.

  • Electroencephalogram (EEG) is a representative diagnostic tool in epilepsy. However, there are several points of debate on the role of EEG in diagnosis and management of epilepsy. We suggest that EEG has some limitations for differential diagnosis from nonepileptic episodic diseases, classification of epilepsy, prediction of recurrence, and evaluation of treatment response. Interictal EEG cannot diagnose or exclude epilepsy because interictal epileptic discharge (IED) is frequently absent in epilepsy and can appear in nonepileptic conditions. Although EEG is helpful in classification of epilepsy, focal spikes in generalized epilepsy and secondary bilateral synchrony in localization related epilepsy cause interrater disagreement. It is controversial whether EEG predicts recurrence after the first seizure in adults. The predictive value of EEG in antiepileptic drug (AED) withdrawal is not absolute. The prognosis after AED withdrawal depends on epilepsy syndrome. Many studies could not confirm the value of EEG in assessing the treatment response. After all, epilepsy is clinically diagnosed and assessed. Interictal EEG alone does not provide decisive information and routine follow-up of EEG is not recommended.
