  • Lymphoepithelioma-like carcinoma (LELC) of the lung is a very rare tumor. Originally described in the nasopharynx as lymphoepithelioma, this carcinoma has also been found in the stomach, esophagus, thymus, cervix, urinary bladder, skin, and salivary glands. Histologically, it is an undifferentiated carcinoma that has a syncytial appearance with tumor cells and is infiltrated by numerous lymphocytes, macrophages, and plasma cells. LELC of the lung occurs more commonly in Asians, particularly Chinese. Many studies have reported the association between Epstein-Barr virus (EBV) and LELC of the lung in Asian patients. A 45-year-old man had a solitary pulmonary nodule on a routine chest X-ray examination. As a malignant tumor was suspected, surgical resection was performed to establish the correct diagnosis. The pathology of the excised tumor demonstrated LELC of the lung. This is the first report of LELC of the lung in Korea.

  • Novel cancer biomarkers are required to achieve early diagnosis and optimized therapy for individual patients. Cancer is a disease of the genome, and tumor tissues are a rich source of cancer biomarkers as they contain the functional translation of the genome, namely the proteome. Investigation of the tumor tissue proteome allows the identification of proteomic signatures corresponding to clinico-pathological parameters, and individual proteins in such signatures will be good biomarker candidates. Tumor tissues are also a rich source for plasma biomarkers, because proteins released from tumor tissues may be more cancer specific than those from non-tumor cells. Two-dimensional difference gel electrophoresis (2D-DIGE) with novel ultra high sensitive fluorescent dyes (CyDye DIGE Fluor satulation dye) enables the efficient protein expression profiling of laser-microdissected tissue samples. The combined use of laser microdissection allows accurate proteomic profiling of specific cells in tumor tissues. To develop clinical applications using the identified biomarkers, collaboration between research scientists, clinicians and diagnostic companies is essential, particularly in the early phases of the biomarker development projects. The proteomics modalities currently available have the potential to lead to the development of clinical applications, and channeling the wealth of produced information towards concrete and specific clinical purposes is urgent.

  • This is a report of multiple myeloma occurred in the left mandibular body and skull. 66-year-old patient was referred to our hospital with a complaint of painful swelling on the left mandibular body area. The author diagnosed it as a multiple myeloma by the clinical examination, radiographic findings, laboratory findings and the histopathological findings. The purpose of this report is to aid in the diagnosis of multiple myeloma and to aid to differentiate it from malignant tumours. The characteristic features are as follows: 1. In clinical examination, painful swelling was observed in left mandibular body area. 2. In radiographic findings, radiograms showed relatively ill-defined radiolucency without sclerotic border in left mandibular body area. And also represented multiple punched-out radiolucency in the skull and pathologic fracture of vertebral body on lumbar 3 level. 3. In histopathologic findings, infiltration of abnormal plasma cells was observed. 4. In laboratory findings, decreasing of albumin/globulin ratio, hypercalcemia, renal impairment was observed, but we could not find the Bence-Jones protein in urin.

  • Variety of biomarkers that are related to the Alzheimer's disease and its diagnosis and progress have been found. However, research lacks in predicting the reaction of the treatment. In addition, there is no definite treatment reaction to the disease but rather it is varied. The purpose of this review article is to study the research of the biomarkers that are able to predict the treatment reaction. There was a research that illustrated a relationship between plasma amyloid ${\beta}$ peptide, cerebrospinal fluid tau, neuroanatomical biomarkers and acetylcholinesterase inhibitors. Polymorphisms in genes of the cholinergic markers AChE, BuChE, ChAT and PON-1 were found to be associated with better clinical response to acetylcholinesterase inhibitors. Many pharmacogenetic studies have been conducted to evaluate the impact of the lipoprotein apolipoprotein E (APOE) genotype on treatment response to acetylcholinesterase inhibitor. However, there is no significant influence of the APOE genotypes on treatment response. Further research is needed to find other predictors of treatment with acetylcholinesterase inhibitors in patients with Alzheimer's disease.

  • Immunoglobulin G4-related disease (IgG4RD) is a chronic inflammatory condition characterized by tissue infiltration with lymphocytes and IgG4-secreting plasma cells, as well as varying degrees of fibrosis. We report a case of a 70-year-old man with a rapid-growing cervical mass for several months. Computed tomography and positron emission tomography showed a huge, ill-defined mass involving left thyroid lobe and encasing the common carotid artery, which was clinically and radiologically suspicious for anaplastic thyroid carcinoma. Ultrasonography-guided core needle biopsy was performed and histopathology examination revealed to be consistent with IgG4RD, and the IgG4/IgG ratio was 0.6. After oral corticosteroid was administered, the mass was dramatically resolved. Because IgG4RD often presents as a single localized and infiltrated mass lesion, it can be confused and misdiagnosed as a malignancy. Thus, clinicians should consider IgG4RD as a differential diagnosis in a rapid-growing neck mass to prevent unnecessary and excessive treatments.

  • Rhabdomyolysis is a syndrome caused by injury to skeletal muscles and involves leakage of large quantities of potentially toxic intracellular contents into the plasma. It is known that rhabdomyolysis results in peripheral nerve injury, however, reports of bilateral sciatic neuropathy following rhabdomyolysis are rare. We report a case involving a 42-year-old female patient with no past medical history, who presented with sudden bilateral calf pain, redness, and burning sensation with weakness of both lower extremities after sleeping on an electric heating pad following alcohol drinking. Lower extremity magnetic resonance angiography (MRA) revealed multifocal edema with enhancement of bilateral lower extremity muscles. Clinical and electrodiagnostic tests were consistent with the diagnosis of bilateral sciatic neuropathy following rhabdomyolysis. This is a rare case of bilateral sciatic neuropathy following rhabdomyolysis.

  • Objectives The purpose of this research is to comprehensively analyze about Jowiseungcheong-tang (Diàowèishēngqīng-tāng). This herbal medicine is widely used to treat obesity and metabolic disease. Methods We used 3 search terms, 'Jowiseungcheong-tang', 'Jowiseungcheong-tang plus obesity' and 'Jowiseungcheong-tang plus metabolic disease' in Korean word via 5 domestic databases. Therefore, 8 laboratory experiments and 4 clinical researches were chosen. Results Jowiseungcheong-tang (Diàowèishēngqīng-tāng) was identified as a herbal medicine for obesity and related metabolic disease. In plasma level of lipid, leptin, inflammatory material were decreased in laboratory experiments. Weight loss and symptom relief were reported in clinical research. Conclusions Definite information about laboratory experiment was showed, specifically suitable index and numerical value. In clinical research, although Jowiseungcheong-tang (Diàowèishēngqīng-tāng) is widely used for obesity and metabolic disease, the number of reported thesis and patient were pretty a few. Also, diagnosis methods were also scanty. Multi-institutional clinical trial should be progressed.

  • Long-chain fatty acid oxidation disorders (LC-FAOD) are an autosomal recessive inherited rare disease group that result in an acute metabolic crisis and chronic energy deficiency owing to the deficiency in an enzyme that converts long-chain fatty acids into energy. LC-FAOD includes carnitine palmitoyltransferase type 1 (CPT1), carnitine-acylcarnitine translocase (CACT), carnitine palmitoyltransferase type 2 (CPT2), very long-chain acyl-CoA dehydrogenase (VLCAD), long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD), and trifunctional protein (TFP) deficiencies. Common symptoms of LC-FAOD are hypoketotic hypoglycemia, cardiomyopathy, and myopathy. Depending on symptom onset, the disease can be divided as neonatal period, late infancy and early childhood, adolescence, or adult onset, but symptoms can appear at any time. The neonatal screening test (NBS) can be used to identify the characteristic plasma acylcarnitine profiles for each disease and confirmed by deficient enzyme analysis or molecular testing. Before introduction of NBS, the mortality rate of LC-FAOD was very high. With NBS implementation as routine neonatal care, the mortality rate was dramatically decreased, but severe symptoms such as rhabdomyolysis recur frequently and affect the quality of life. Triheptanoin (Dojolvi®), the first drug for pediatric and adult patients with molecularly confirmed LC-FAOD, has recently been approved by the US Food and Drug Administration in 2020. In this review, the diagnosis of LC-FAOD and treatment including triheptanoin are summarized.

  • Acute myocardial infarction (AMI) is a multifaceted syndrome influenced by the functions of various extrinsic and intrinsic pathways and pathological processes, which can be detected in circulation using biomarkers. In this study, we investigated the secretome protein profile of induced-hypertrophy cardiomyocytes to identify next-generation biomarkers for AMI diagnosis and management. Hypertrophy was successfully induced in immortalized human cardiomyocytes (T0445) by 200 nM ET-1 and 1 μM Ang II. The protein profiles of hypertrophied cardiomyocyte secretomes were analyzed by nano-liquid chromatography with tandem mass spectrometry and differentially expressed proteins that have been identified by Ingenuity Pathway Analysis. The levels of 32 proteins increased significantly (>1.4 fold), whereas 17 proteins (<0.5 fold) showed a rapid decrease in expression. Proteomic analysis showed significant upregulation of six 14-3-3 protein isoforms in hypertrophied cardiomyocytes compared to those in control cells. Multi-reaction monitoring results of human plasma samples showed that 14-3-3 protein-zeta levels were significantly elevated in patients with AMI compared to those of healthy controls. These findings elucidated the role of 14-3-3 protein-zeta in cardiac hypertrophy and cardiovascular disorders and demonstrated its potential as a novel biomarker and therapeutic strategy.
