Present study aimed to investigate the immunological activities of cell wall associated protein antigen solubilized with Triton X-100 (TSP) from Mycobacterium tuberculosis H37Rv and conducted on 43 patients with pulmonary tuberculosis (newly diagnosed, medicated within 12 months and chronic refractory patients) and 17 normal healthy controls. These immunological responses were compared with those induced by the PPD or 30 kDa antigen from M, tuberculosis H37Rv culture filtrates, identified as biologically important secreted proteins. Proliferative responses to mycobacterial antigens were compared in peripheral blood mononuclear cells (PBMC) of healthy subjects and pulmonary tuberculosis patients. Signiticant blastogenic responses to the TSP were observed in healthy tuberculin reactors, newly diagnosed and some of antituberculosis drug-medicated patients by H-thymidine incorporation assay. IL-12 p40 and IFN-r mRNA expressions to the TSP were markedly increased, whereas IL-10 and TNF-a mRNA expressions were decreased at a 5 day-stimulation by PBMC in healthy tuberculin reactors, newly diagnosed and medicated patients. However, patients with chronic refractory tuberculosis exhibited more depressed IL-12 p40 and IFN-r mRNA expressions to all of the antigens than another groups. Interestingly, very low IL-10 and TNF-a mRNA expressions cultured with the TSP were also shown. These data suggest that the TSP may be involved in the macrophage activation by induction of Th1 stimulatory signals, such as IL-12, and suppression of Th1 inhibitory cytokine, IL-10.

PURPOSE: The aim of this study was to evaluate the utility of contrast-enhanced MRI with first-pass and delayed images in prediction of myocardial viability after acute myocardial infarction. MATERIALS AND METHODS: Ten patients (M:F=:4, mean age =6 5 years) with acute myocardial infarction underwent first-pass image after bolus injection of gadolinium (one image/sec for 120sec)and delayed image (7 2 minutes later). According to 60 segments on midventricular level, the assessment of MRI were concerned about location of lesion, depth of lesion, enhancement on first-pass image and enhancement pattern on delayed image. MRI findings were compared with wall motion on resting echocardiography and stress or follow-up echocardiography. RESULTS: 1) MRI findings were classified into 4 types: normal enhancement on first-pass and delayed images (type 1), normal enhancement on first-pass image and nontransmural hyperenhancement on delayed image (type 2), non-transmural enhancing defect on first-pass image and transmural enhancement with endocardial non-enhancing defect on delayed image (type 3), and transmural enhancing defect on first-pass image and transmural hyperenhancement on delayed image (type 4).2) Type 2 suggested viable myocardium and type 3 had high porbability of viability. Type was compatible with non-viable myocardium. CONCLUSION: Enhancing defect on first-pass image and involving thickness on both the first-pass image and delayed image in contrast enhanced MRI may predict myocardial viability.

Cervical pregnancy is a rare and dangerous form of ectopic pregnancy in which the blastocyst implants within the cervical canal below the internal os of the uterine cervix. The characteristic clinical sign is a severe asymptomatic uterine bleeding in early pregnancy or during curettage. Most cervical pregnancies result in early spontaneous abortion, complicated by severe hemorrhage from the eroded blood vessels within the cervical tissue. Because of uncontrolled profuse vaginal bleeding, total hysterectomy has been the mostly necessitated to control life-threatening bleeding. Transvaginal sonography allows early diagnosis, and conservative treatment (two-time treatment : first treatement with systemic or intraamnionic methotrexate, secondly with curettage or ligature of the uterine arteries) improves the patient's fertility. Successful treatment is defined as elimination of the cervical pregnancy with preservation of the uterus. We report two cases of cervical pregnancy managed, successfully with methotrexate, leucovorin and curettage.

Background:
An evident relationship has been shown between psoriasis and metabolic comorbidities. However, the results in pediatric psoriasis vary from study to study, and no meta-analysis exists on the association of metabolic comorbidities with pediatric psoriasis. Objective: To evaluate the association between psoriasis and metabolic comorbidities in pediatric patients.
Methods:
We searched articles published in PubMed, EMBASE, and Cochrane Library databases from inception to April 30, 2019. All observational studies reporting the prevalence of obesity or metabolic comorbidities in pediatric patients with psoriasis were included.
Results:
The meta-analysis included 16 unique studies meeting the inclusion criteria. The pooled odds ratios in pediatric patients with psoriasis was 2.40 (95% confidence interval [CI], 1.60∼3.59) for obesity (13 studies), 2.73 (95% CI, 1.79∼ 4.17) for hypertension (8 studies), 2.01 (95% CI, 1.09∼3.73) for diabetes mellitus (8 studies), 1.67 (95% CI, 1.42∼1.97) for dyslipidemia (7 studies), and 7.49 (95% CI, 1.86∼30.07) for metabolic syndrome (4 studies).
Conclusion
Pediatric patients with psoriasis showed a significantly higher prevalence of obesity, hypertension, diabetes, dyslipidemia, and metabolic syndrome. Adequate monitoring and timely management of metabolic comorbidities should be considered in these patients.

Marchiafava-Bignami disease (MBD) is characterized by cerebral white matter lesions associated with chronic alcoholism. Premortem diagnosis of MBD is usually based on history and clinical manifestations. We report a case of acute MBD in which diffusion-weighted MRI (DWI) showed high signal intensities along the white matter including the corpus callosum. DWI may be useful in premortem diagnosis of acute MBD.

Mitochondria are key organelles involved in energy production, functioning as the metabolic hubs of cells. Recent findings emphasize the emerging role of the mitochondrion as a key intracellular signaling platform regulating innate immune and inflammatory responses. Several mitochondrial proteins and mitochondrial reactive oxygen species have emerged as central players orchestrating the innate immune responses to pathogens and damaging ligands. This review explores our current understanding of the roles played by mitochondria in regulation of innate immunity and inflammatory responses. Recent advances in our understanding of the relationship between autophagy, mitochondria, and inflammasome activation are also briefly discussed. A comprehensive understanding of mitochondrial role in toll-like receptor-mediated innate immune responses and NLRP3 inflammasome complex activation, will facilitate development of novel therapeutics to treat various infectious, inflammatory, and autoimmune disorders.

PURPOSE: Total anomalous venous return(TAPVR) is associated in more than 60Yo of patients with right isomerism and can significantly complicate the management of single ventricle patients at any stage of management. We studied the results of management and sought to determine factors that may influence survival in patients with TAPVR in right atrial isomerism. METHODS: Between February 1991 and July 1999, 14 patients with TAPVR in right atrial isomerism underwent operations,' we reviewed our experience after performing single ventricle palliation RESULTS: Seven patients were of the obstructive type TAPVR and seven patients were of the non-obstructive type TAPVR. The mean age at operation was 17 months and mean body weight at operation was 7.3kg. Direct surgical repair for the pulmonary vein was performed in seven patients and in the others, TAPVR could be satisfactorily managed by the use of bilateral cavopulrnonary anastomosis(BCPS) to exclude the distal superior vena cava(SVC). At a mean follow-up of 27 months, there were five deaths, arid pulrnonary vein restenosis developed in four patients in the direct surgical repair group. In the other group, there was neither mortality nor morbidity. Also, the presence of pulmonary venous obstruction was associated with high mortality. CONCLUSION: According to our study, TAPVR can be satisfactorily managed by the use of BCPS to exclude the distal SVC in the non-obstructive type. But further evaluation of surgical methods about other types of TAPVR are warranted, because TAPVR not requiring intervention includes any low supracardiac and some mixed types.
