Heterotopic pregnancy occurs when an intrauterine pregnancy co-exists with an ectopic pregnancy. It is a potentially fatal condition, rarely occuring in natural conception cycle. But its incidence is increased since the rise in PID, pelvic surgery, IUD, and advent of assisted reproductive technology involving use of superovulatory drugs and/or in vitro-fertilization. We present a case of intrauterine twin pregnancy and right tubal pregnancy following treatment with in vitro-fertilization. The right tubal pregnancy was diagnosed after rupturing at 6th gestational weeks, and resected via laparoscopy. And healthy twin babies were delivered without complication at 38th gestational week. So we report this case with a brief review of the literatures.

The purpose of this study was to compare food intakes between Korean breast cancer patients and a healthy control group. We compared the intake of nutrients of 117 food items between Korean breast cancer patients (n=97) and age matched healthy controls (n=97). Nutrient intake was estimated using a quantitative food frequency questionnaire. The mean caloric intake of breast cancer patients and healthy controls was not significantly different. Breast cancer patients consumed significantly less fat and antioxidant nutrients such as vitamin A, retinol, beta-carotene, vitamin C and vitamin E when compared to the control subjects. Among the food items, the intake of eggs (p<0.01), legumes (p<0.05), vegetables (p<0.05), seasonings (p<0.001), and oils and fats (p<0.01) in breast cancer patients was significantly lower than that in the controls. These results suggest that Korean breast cancer patients consumed less amount of soy and vegetables, which are rich source of antioxidant nutrients and phytosterols. Thus, dietary guidance to increase intake of these foods may be beneficial in the prevention of breast cancer.

In allogeneic transplantation, including the B6 anti-BALB.B settings, H60 and H4 are two representative dominant minor histocompatibility antigens that induce strong CD8 T-cell responses. With different distribution patterns, H60 expression is restricted to hematopoietic cells, whereas H4 is ubiquitously expressed. H60-specific CD8 T-cell response has been known to be dominant in most cases of B6 anti-BALB.B allo-responses, except in the case of skin transplantation. To understand the mechanism underlying the subdominance of H60 during allogeneic skin transplantation, we investigated the dynamics of the H60-specific CD8 T cells in B6 mice transplanted with allogeneic BALB.B tail skin. Unexpectedly, longitudinal bioluminescence imaging and flow cytometric analyses revealed that H60-specific CD8 T cells were not always subdominant to H4-specific cells but instead showed a brief dominance before the H4 response became predominant. H60-specific CD8 T cells could expand in the draining lymph node and migrate to the BALB.B allografts, indicating their active participation in the anti-BALB.B allo-response. Enhancing the frequencies of H60-reactive CD8 T cells prior to skin transplantation reversed the immune hierarchy between H60 and H4. Additionally, H60 became predominant when antigen presentation was limited to the direct pathway. However, when antigen presentation was restricted to the indirect pathway, the expansion of H60-specific CD8 T cells was limited, whereas H4-specific CD8 T cells expanded significantly, suggesting that the temporary immunodominance and eventual subdominance of H60 could be due to their reliance on the direct antigen presentation pathway. These results enhance our understanding of the immunodominance phenomenon following allogeneic tissue transplantation.

BACKGROUND: Disparities of Minor H antigens can induce graft rejection after MHC-matched transplantation. H60 has been characterized as a dominant antigen expressed on hematopoietic cells and considered to be an ideal model antigen for study on graft-versus-leukemia effect. METHODS: Splenocytes from C57BL/6 mice immunized with H60 congenic splenocytes were used for establishment of H60-specific CTL clones. Then the clones were characterized for proliferation capacity and cytotoxicity after stimulation with H60. Clone #14, #15, and #23 were tested for the TCR binding avidity to H60-peptide/H-2Kb and analyzed for TCR sequences. RESULTS: H60-specific CTL clones showed different levels of proliferation capacity and cytotoxic activity to H60-stimulation. Clones #14, #15, and #23 showed high proliferation activity, high cytotoxicity, and low activities on both aspects, respectively, and have TCRs with different binding avidities to H60-peptide/H-2Kb with t 1/2 values of 4.87, 6.92, and 13.03 minutes, respectively. The TCR usages were Valpha12D-3-01+Jalpha11-01 and Vbeta12-1-01+Dbeta1-01+J2-7-01 for clone #14, Valpha13D-1-02+Jalpha34-02 and Vbeta13-1-02+Dbeta2-01+Jbeta2-7-01 for clone #15, and Valpha16D+Jalpha45-01 and Vbeta12-1-01+Dbeta1-01+Jbeta2-5-01 for clone #23. CONCLUSION: The results will be useful for modeling GVL and generation TCR transgenic mouse.

The management of severe recalcitrant atopic dermatitis (AD) is a challenging issue for clinicians and patients. We hypothesized that repeated intramuscular injections of autologous immunoglobulin (autologous immunoglobulin therapy: AIGT) might induce clinical improvements in patients with AD by stimulation of the active immune response to antigen-binding-site of pathogenic antibodies. We tried AIGT in 3 adult patients with severe recalcitrant AD whose clinical conditions could not be effectively controlled by medical treatments (including oral cyclosporine) for more than 2 years. Autologous immunoglobulin was purified from the autologous plasma by affinity chromatography using Protein A. The patients were treated by an intramuscular injection of 50 mg of autologous immunoglobulin twice a week for 4 weeks. A clinical severity score of AD (SCORAD value) showed a decrease greater than 30% at 8 weeks after the initiation of AIGT compared with the baseline before the initiation of AIGT in all 3 patients with severe recalcitrant AD. No significant side effects from treatment were observed. Further studies with larger numbers of patients are required to evaluate the clinical usefulness of AIGT for AD.

PURPOSE: Mycoplasma pneumoniae is one of the most common causes of pneumonia in children and adolescents. Though cold agglutinin test and specific antibody test are used in the diagnosis of mycoplasma pneumonia, there are some limitations in early diagnosis. In this study, we evaluated the availability and usefulness of polymerase chain reaction (PCR) in the diagnosis of M. pneumoniae pneumonia and compared it with serologic test. METHODS: One hundred twenty four children who were clinically diagnosed with pneumonia and admitted to Kyunghee Hospital from January 1998 to March 2001 were enrolled. Mycoplasma specific antibody test using commercial kit (Serodia-MYCO II, Fusirebio Inc., Tokyo, Japan) and PCR using mycoplasma DNA obtained from throat swabs were done. The sensitivity and specificity of PCR were evaluated. RESULTS: M. pneumoniae pneumonia was diagnosed when the mycoplasma specific antibody titer was over 1: 160 or when the titer increased more than fourfold during follow-up period. The specificity, sensitivity, false-positive rate and false-negative rates of PCR were 93.0%, 58.3%, 33.3%. and 9.7%, respectively. CONCLUSION: PCR has shown high specificity. But, the positive result in PCR don't correlate with the disease activity and PCR does not have high sensitivity. So PCR must be used alongside with serologic test in the diagnosis of pneumonia. But, it seems possible to improve sensitivity by delicate handling of samples and by improving PCR technology, and PCR will possibly be used in the diagnosis of early infections of M. pneumoniae pneumonia and in the evaluation of treatments in the future.

Photoacoustic imaging (PAI) is a new promising medical imaging technology available for diagnosing and assessing various pathologies. PAI complements existing imaging modalities by providing information not currently available for diagnosing, e.g., oxygenation level of the underlying tissue. Currently, researchers are translating PAI from benchside to bedside to make unique clinical advantages of PAI available for patient care. The requirements for a successful clinical PAI system are; deeper imaging depth, wider field of view, and faster scan time than the laboratory-level PAI systems. Currently, many research groups and companies are developing novel technologies for data acquisition/signal processing systems, detector geometry, and an acoustic sensor. In this review, we summarize state-of-the-art clinical PAI systems with three types of the imaging transducers: linear array transducer, curved linear array transducer, and volumetric array transducer. We will also discuss the limitations of the current PAI systems and describe latest techniques being developed to address these for further enhancing the image quality of PAI for successful clinical translation.

Journal of Korean Physical Therapy 2020;32(4):250-257
Purpose:
This study examined the effects of training using the slime on the hand function and problem behavior in adults with intellectual disabilities.
Methods:
Five adults with intellectual disabilities who were judged as Level 1 or Level 2 were selected. The training consisted of one session (50 min)/day, one day/week for 10 weeks (preparatory activities: 5 min, slime activities: 40 min, finishing activities: 5 min) The functions of the hand (Purdue Pegboard Test [PPT], grip strength test [GST]) and problem behavior (Korean Behavior Problems Inventory [K-BPI]) were assessed three times (first assessment; pre, second assessment; post-5 weeks, third assessment; post-10 weeks). Wilcoxon signed-rank tests were used to analyze changes in the subjects’ performance before and after the intervention.
Results:
In the PPT, the use of the non-dominant hand was increased significantly (p<0.05). No significant differences were observed in the remaining results, but the mean value increased. In addition, although the problem behavior was not statistically significant, an increase in the problem behavior score was noted.
Conclusion
The training using the slime for adults with intellectual disabilities is effective in hand function improvement and reducing problem behavior.

The increased expression of receptors for advanced glycation endproduct (RAGE) is known as a key player in the progression of vascular remodeling.However, the precise signal pathways regulating RAGE expression in vascular smooth muscle cells (VSMCs) in the injured vasculatures are unclear. Given the importance of mitogen-activated protein kinase (MAPK) signaling in cell proliferation, we investigated the importance of MAPK signaling in high-mobility group box 1 (HMGB1)-induced RAGE expression in VSMCs. In HMGB1 (100 ng/ml)-stimulated human VSMCs, the expression of RAGE mRNA and protein was increased in association with an increase in AGE-induced VSMC proliferation. The HMGB1-induced RAGE expression was attenuated in cells pretreated with inhibitors for ERK (PD98059, 10 μM) and p38 MAPK (SB203580, 10 μM) as well as in cells deficient in ERK and p38 MAPK using siRNAs, but not in cells deficient of JNK signaling. In cells stimulated with HMGB1, the phosphorylation of ERK, JNK, and p38 MAPK was increased. This increase in ERK and p38 MAPK phosphorylation was inhibited by p38 MAPK and ERK inhibitors, respectively, but not by JNK inhibitor. Moreover, AGE-induced VSMC proliferation in HMGB1-stimulated cells was attenuated in cells treated with ERK and p38 MAPK inhibitors. Taken together, our results indicate that ERK and p38 MAPK signaling are involved in RAGE expression in HMGB1-stimulated VSMCs. Thus, the ERK/p38 MAPKRAGE signaling axis in VSMCs was suggested as a potential therapeutic target for vascular remodeling in the injured vasculatures.
