Purpose: A personal computer-based system was developed for automated metabolic profiling of organic aciduria and aminoacidopathy by gas chromatography-mass spectrometry and data interpretation for the diagnosis of metabolic disorders Methods: For automatic data profiling and interpretation, we compiled retention time, two target ions and their intensity ratio for 77 organic acids and 13 amino acids metabolites. Metabolites above the cut-off values were flagged as abnormal compounds. The data interpretation was a based on combination of flagged metabolites. Diagnostic or index metabolites were categorized into three groups, "and", "or" and "NO" compiled for each disorder to improve the specificity of the diagnosis. Groups "and" and "or" comprised essential and optional compounds, respectively, to reach a specific diagnosis. Group "NO" comprised metabolites that must be absent to make a definite diagnosis. We tested this system by analyzing patients with confirmed Propionic aciduria and others. Results: In all cases, the diagnostic metabolites were identified and correct diagnosis was founded to be made among the possible disease suggested by the system. Conclusion: The study showed that the developed method could be the method of choices in rapid, sensitive and simultaneous screening for organic aciduria and amino acidopathy with this simplified automated system.

Objective : This study was carried out to investigate the progress of bilateral simultaneous facial palsy and the effect of Hominis Placenta herbal-acupunture and the other oriental medical therapies. Method : We used two methods to research the progress of disease. 1. Diagnosis - Facial muscle test, Taste test, Hearing test, Photographies, Lab-finding 2. Treatment - Acupuncture, Herbal-acupuncture, Electroacupuncture, Herb-med Edema rate, Pain endurance, WBC, Hemoglobin, Platelet, Total protein, Albumin, Globulin, RA factor, CRP Results : The onset of Rt. facial palsy was earlier than Lt. facial palsy 3days. The reaction on the treatment of Rt. facial palsy was more dull than Lt. facial palsy. In terms of treatment period, Rt. facial palsy was very longer than Lt. facial palsy. Conclusion : According to the above results, we discoveried that Hominis Placenta herbal-acupunture and the other oriental medical therapies had good influence on the bilateral simultaneous facial palsy. In the future, we should endeavor to know influence between Rt. and Lt. face in case of bilateral simultaneous Bell's palsy.

Northern corn leaf spot and southern corn leaf blight caused by Cochliobolus carbonum (anamorph, Bipolaris zeicola) and Cochliobolus heterostrophus (anamorph, Bipolaris maydis), respectively, are common maize diseases in Korea. Accurate detection of plant pathogens is necessary for effective disease management. Based on the polyketide synthase gene (PKS) of Cochliobolus carbonum and the nonribosomal peptide synthetase gene (NRPS) of Cochliobolus heterostrophus, primer pairs were designed for PCR to simultaneously detect the two fungal pathogens and were specific and sensitive enough to be used for duplex PCR analysis. This duplex PCR-based method was found to be effective for diagnosing simultaneous infections from the two Cochliobolus species that display similar morphological and mycological characteristics. With this method, it is possible to prevent infections in maize by detecting infected seeds or maize and discarding them. Besides saving time and effort, early diagnosis can help to prevent infections, establish comprehensive management systems, and secure healthy seeds.

Lemierre's syndrome is rare disease characterized by anaerobic sepsis, internal jugular vein thrombosis, septic emboli that resulted from head and neck infection. Lemierre's syndrome has significant morbidity, so immediate, accurate diagnosis and treatment is needed. It is necessary to perform contrast-enhanced computed tomography (CT) for diagnosis. Systemic antibiotics is recommended, and surgical interventions, anticoagulation may beis considered for treatment. We report misdiagnosed case as a simple deep neck infection on initial ultrasonography with simultaneous abscess aspiration but finally diagnosed and treated internal jugular vein thrombophlebitis (Lemierre's syndrome) on CT scan. We report a case of a 45-year-old patient, who was diagnosed with a simple deep neck infection and treated with simultaneous abscess aspiration, but finally diagnosed and treated internal jugular vein thrombophlebitis (Lemierre's syndrome) on CT scan.

The economic impact of swine mycoplasma infection is high. An accurate diagnosis is often difficult and time consuming. We report the development and validation of an effective multiplex polymerase chain reaction (PCR) assay that detects Mycoplasma (M.) hyopneumoniae and M. hyorhinis. The multi detection of M. hyopneumoniae and M. hyorhinis primer set were employed to detect mycoplasma species and typing of the species was performed on the basis of sequence analysis of the PCR product. The target nucleic acid fragments were specifically amplified by M. hyopneumoniae and M. hyorhinis PCR with 16S ribosomal DNA primers. Single and mixed Mycoplasma species DNA templates were used to evaluate the specificity of the multiplex assay. The corresponding specific DNA products were amplified for each pathogen. The multiplex PCR assay provides a novel tool for simultaneous detection and differentiation of M. hyopneumoniae and M. hyorhinis.

Objective: This study was designed to investigate the possibility of quantification of the diagnosis of abdominal coldness (AC) in patients with functional dyspepsia (FD). Methods: Forty-four patients with FD were enrolled in this study. Three Korean medicine doctors each randomly examined all abdomens. Diagnosis of AC was made by consensus of at least two of the doctors. Body temperature (oral by digital oral thermometer) and skin temperature (by digital infrared thermal imaging [DITI]) were measured, followed by administration of the Cold and Heat questionnaire (CHQ) and the Instrument of Pattern Identification for Functional Dyspepsia (IPIFD). Results: Of the 44 patients with FD, 22 were assigned to the AC group and 22 to the non-AC group. The concordance rate of diagnosis among the three doctors was 63.6% (28/44), with a ${\kappa}$ of 0.504, indicating means moderate agreement). Neither the oral nor the skin temperatures showed statistically significant differences between the AC and non-AC groups. However, the CHQ scores and 'Simultaneous Occurrence of Cold and Heat Syndromes pattern' scores of the IPIFD were higher in AC group and showed statistically significant differences (p=0.010 and 0.009). Conclusions: This is the first study conducting quantitative measurements of abdominal coldness in patients with FD. Although oral and skin temperature showed no statistical significance between AC and non-AC groups, the concordance rate of diagnosis of AC among the three Korean Medicine doctors was moderate. The CHQ scores and 'Simultaneous Occurrence of Cold and Heat Syndromes pattern' scores of the IPIFD also suggest that diagnosis of AC is relevant to cold and heat patterns, and these questionnaires could be utilized as supportive data for the diagnosis of AC. Further studies should be conducted for the purpose of quantifying and standardizing abdominal examinations in Korean Medicine.

Inherited metabolic disorders (IMD) are a group of disorders involving various metabolic pathways. Genetic diagnosis of IMD has been challenging because of extremely heterogeneous nature and extensive laboratory and/or phenotype overlap. Conventional genetic diagnosis was a gene-by-gene approach that needs a priori information on the causative genes that might underlie the IMD. Recent implementation of next-generation sequencing (NGS) technologies has changed the process of genetic diagnosis from a gene-by-gene approach to simultaneous analysis of targeted genes possibly associated with the IMD using gene panels or using whole exome/genome sequencing (WES/WGS) covering entire human genes. Clinical NGS tests can be a cost-effective approach for the rapid diagnosis of IMD with genetic heterogeneity and are becoming standard diagnostic procedures.
