Abstract
Objectives The objective was to investigate the microscopic artifacts made in the uterus of cervical high-grade squamous intraepithelial lesion (HSIL) resected by hysterectomy through minimally invasive (H-MI) procedures and to verify whether these specimens are suitable for histopathological assessment. Materials and Methods This single-center retrospective study analyzed 28 patients with cervical HSIL, consisting of 21 premenopausal and seven postmenopausal women, who underwent H-MI. The proportion of the cervical mucosa covered by intact surface epithelium (residual ratio [RR]) was measured on microscopically. Surgical margin's status was also verified. Results All cases developed detachment of the cervical surface epithelium to a varying extent. The RR was significantly higher in the premenopausal patients (median: 75.5%) than in the postmenopausal patients (median: 37.6%). Among the premenopausal patients, the RR was lower in the cases on whom uterine manipulator (UM) was used (median: 70.5%) than in the cases without UM use (median 92.7%). Among the 21 cases whose resected uterus contained HSIL, the vaginal resection margin was not assessable in three (14.2%) of the seven postmenopausal cases due to the artifact. Conclusion Although transvaginal manipulation of the uterus causes detachment of the cervical surface epithelium, H-MI for cervical HSIL provides an acceptable specimen for histological assessment in premenopausal patients, even if UM is used. In postmenopausal women, H-MI easily develops artifactual loss of cervical surface epithelium, sometimes providing an unfavorable specimen for microscopic assessment.

Abstract
OBJECTIVE Clinically amyopathic dermatomyositis (CADM) patients frequently develop refractory interstitial lung disease (ILD), with a poor prognosis. We aimed to verify the efficacy and safety of plasma exchange (PE) treatment for ILD in CADM. METHOD A retrospective case-control study was conducted to compare clinical outcomes with and without PE treatment in CADM-ILD patients refractory to combination therapy of high-dose glucocorticoids, calcineurin inhibitors, and cyclophosphamide. Among 19 enrolled patients, 11 were further treated with PE. We compared survival rates and other clinical characteristics. PE consisted of either fresh-frozen plasma or albumin as a replacement solution. RESULTS Basal clinical characteristics at diagnosis, including age, gender, serum ferritin, Krebs von den Lungen-6 (KL-6), C-reactive protein, and respiratory function tests, did not differ between the two groups. The survival rate for treatment with PE was higher than for treatment without PE (91% and 50%, respectively, p < 0.05). Among PE-treated patients, anti-melanoma differentiation-associated gene-5 (anti-MDA-5) antibody titre, ferritin, and KL-6 as serological activity markers were sustainably reduced only after initiating PE. Therapeutic intervention with PE reduced the frequency of exacerbation of ILD requiring methylprednisolone pulse therapy. The occurrence of bacterial, fungal, and cytomegalovirus infection did not differ between the groups with and without PE, and adverse events associated with PE resolved with appropriate intervention. CONCLUSION Combination therapy with PE was associated with an improved survival rate, and may be effective for the management of refractory ILD in CADM patients. A personalized therapeutic strategy including PE could be introduced for fatal rapidly progressive ILD.

Abstract
Introduction In our previous study, we have developed the Child Psychosis-risk Screening System (CPSS), which incorporates psychological and behavioral characteristics of childhood into an algorithm, based on a retrospective survey. Objectives In this study, we actually tried to evaluate the risk of psychosis in pediatric and psychiatric outpatients using the CPSS. Methods We conducted an epidemiological study of 323 outpatients aged 6-18 years visiting pediatric and psychiatric departments using CBCL and clinical data (sex, age, winter birth, chief complaint, diagnosis, abuse, bullying, hikikomori). ROC analysis was used to assess the accuracy of CPSS predictions. Cross-sectional logistic regression analysis was performed on the clinical data to identify factors associated with risk groups exceeding the cutoff value. Results The results of the ROC analysis showed that the AUC (Area under the ROC Curve) was 80.3%, indicating that the CPSS has Moderate accuracy. The cutoff value was 98.11% (sensitivity: 0.857, specificity: 0.835), and 18% of the subjects were identified as risk groups above this value. Cross-sectional logistic regression analysis showed that schizophrenia diagnosis, no abuse, winter birth, and hikikomori were associated with the risk group, with respective odds ratios of 22.88, 10.76, 1.91, and 1.37. Conclusions The results of this study suggest that the CPSS can be applied to pediatric practice for early detection of risk for psychosis. The risk group is also present among pediatric patients with physical chief complaints. The factors suggested to be associated with risk groups may reflect the factors acting on the critical period of psychosis onset and the dynamic state. Disclosure No significant relationships.

Abstract
Introduction Previously, we conducted a statistical case-control study of adolescent Hikikomori patients in Japan using the Parental Assessment of Psychological, Behavioral and Environment Scales. That study did not reveal any pathologies specific to Hikikomori patients. On the other hand, environmental factors such as “lack of communication between parents” and “overuse of the Internet” were shown to be significant predictors of Hikikomori severity. Objectives In this study, using the same methodology as our previous study in Japan, we conducted a case-control study in France. The following questions were examined : (1) whether the pathology of Hikikomori patients in Japan and France is the same, and (2) whether the environmental factors associated with the severity of Hikikomori are the same in Japan and France. Methods Using CBCL and our original scales, we descriptive-statistically compared clinical and subclinical psycho-behavioral characteristics of adolescent Hikikomori patients and a control group. In addition, environmental factors that make Hikikomori more severe were clarified by multiple regression analysis. Results The results showed that there was no difference in the pathology of Hikikomori between Japan and France. On the other hand, the statistical predictors of Hikikomori severity were “lack of communication between parents and children” and “Lack of communication with the community,” which differed from those in Japan. Conclusions Although it is safe to assume that Japanese and French Hikikomori’s pathology is generally the same, different strategies may be needed to prevent the onset of Hikikomori and to stop it from becoming severe.

Abstract
Introduction Children in a prodromal state manifesting as truancy or social isolation (hikikomori) often complain of problems that are physical in nature and are subject to significant changes. We developed the Child Psychosis-Risk Screening System (CPSS) that incorporates childhood psycho-behavioral characteristics revealed through a retrospective survey of schizophrenia patients into its algorithm. Objectives Our research aimed to test the risk identification of pediatric and psychiatric clinic outpatients using the CPSS. Methods We conducted an epidemiological study involving 204 outpatients between the ages of 6 and 14 years who had been examined at a pediatric or psychiatric clinic using the CBCL and clinical data from medical charts. Logistic regression analysis and T-tests were performed using each clinical data variable to clarify the risk of the CPSS calculated from the CBCL data and contributing factors. Results The results of the logistic regression analysis demonstrated that the diagnostic category (physical illness or DSM-5 diagnosis) and chief complaint did not contribute to differentiate between the high-risk and low-risk groups. Meanwhile, the environmental factors of “abuse” and “social isolation” did contribute to the discrimination of the two groups. Conclusions The fact that the diagnostic category during childhood does not contribute to the discrimination of the high- risk group warrants attention. It is possible that the high-risk group only had a latent endophenotype that had not yet manifested during this period. The factors suggested to have an association with the high-risk group may be reflecting activators and the dynamic state of the critical period for psychosis. Disclosure No significant relationships.

Abstract
Introduction Social withdrawal, or hikikomori, is one of Japan’s most serious psychosocial issues. The concept gained international attention around 2010 and widespread psychiatric epidemiological studies have since been conducted. Objectives With an understanding of the extensive range of hikikomori circumstances as a spectrum, we aimed to quantitatively measure the severity of hikikomori in adolescent subjects, an age group considered particularly susceptible to the condition, and to identify factors associated with its severity. Methods We selected population demographics, socioeconomic data, and psycho-behavioral characteristics as factors related to hikikomori and explored their associations with hikikomori severity using cross-sectional analysis. Subjects were a patient group of middle school students examined as outpatients at a psychiatric clinic during adolescence for a chief complaint of hikikomori and a control group of middle school students matched for sex and age. Subjects’ parents completed a questionnaire pertaining to their child’s hikikomori symptoms and living environment along with the Child Behavior Checklist (CBCL). The data collected was then statistically analyzed. Results T-test results demonstrated that scores for all CBCL syndrome scales were significantly higher in the patient group, but no scores fell within the clinical range. Multiple regression analysis revealed that being anxious/depressed, somatic complaints, lack of communication between parents, and overuse of the Internet were statistical predictors of hikikomori severity. Conclusions It may be possible to prevent hikikomori from becoming severe if the above predictors are used to identify high-risk individuals requiring active intervention while hikikomori is at an early stage.

Abstract
Vascular-type Ehlers-Danlos syndrome (vEDS) is an autosomal-dominant inherited disorder caused by a deficit in collagen III. It results from heterogeneous mutations in the α1 collagen III gene (COL3A1) and is associated with life-threatening complications, even in younger patients. However, the details of the pathogenesis underlying the COL3A1 mutation causing vEDS remain unclear. Here, we focus on anomalies in collagen fiber size and the endoplasmic reticulum (ER) stress response in patients with vEDS using electron microscopy (EM). We discovered that although the infants did not have vEDS, collagenous formations were similar to their samples in vEDS. Moreover, we examined the expression of activating transcription factor 6 (ATF6) as an ER stress marker and cartilage oligomeric matrix protein (COMP) as a binding partner protein for collagen fibrils in the dermis and COL3A1. The expression levels of ATF6 in the vEDS group were significantly higher than in infants and controls; COMP and COL3A1 levels were significantly lower. The fragile collagen fibrils in vEDS might form as a result of ER stress and that small, newly formed collagen fibrils may appear. This research revealed a novel prospect regarding an issue that has been unclear for a long time, which is the reason for the abnormal sizes of collagenous fibrils in vEDS.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) refers to a group of diseases, characterized by abnormal proliferation of lymphocytes, that develop after organ transplantation. PTLD is associated with poor prognosis, and has become a major problem for transplant patients. In this report, we described a case of malignant lymphoma of the cervix in a bicollis uterus considered to be a PTLD in a patient after renal transplantation. The incidence of this disease is expected to increase as the survival rate of transplant patients improves. Hence, it is very important for gynecological oncologists to consider the presence of PTLD when examining such patients.

Abstract
Prostaglandin D2 (PGD2 ) plays an important role in atopic dermatitis (AD), and 11,15-dioxo-9α-hydroxy-2,3,4,5-tetranorprostan-1,20-dioicacid (PGDM) is a major metabolite of PGD2 . We investigated the relationship between urinary PGDM levels and severity of paediatric AD. In total, 31 patients with AD and 21 healthy controls (HCs) without AD were recruited, and urinary PGDM levels were measured. Of the 31 patients with AD, 14 were reassessed for urinary PGDM after topical steroid therapy. There was no difference in urinary PGDM levels between patients with AD and HCs. Although there was a significant positive correlation between the SCORing Atopic Dermatitis (SCORAD) index and the serum level of thymus and activation-regulated chemokine (TARC), the urinary PGDM levels did not correlate with either SCORAD or serum TARC. Moreover, both SCORAD and serum TARC were significantly improved by topical steroid therapy; however, urinary PGDM levels were not changed. In conclusion, the level of urinary PGD2 metabolites in children with AD is substantially the same as that in HCs even if the disease is severe.

Abstract
Potassium iodide (KI), initially derived from seaweed in the early 19th century, is used for treating sporotrichosis in dermatological practice. KI has also been used to treat several noninfectious inflammatory skin diseases. However, the mechanisms underlying the improvement in such skin diseases remain unknown, and KI is not used widely. Thus, although KI is an old drug, physicians may not prescribe it frequently because they lack knowledge about it. Although KI is very inexpensive and causes few side effects, it has been superseded by new powerful and expensive drugs, such as biological agents. We applied 3% KI topically to areas of inflammation induced by SDS in mice. The levels of IL-1 and TNF-α gene expression were reduced, whereas that of IL-10 gene expression was increased. Small interfering RNA that was designed to reduce IL-10 gene expression levels was injected into the same mice, and the anti-inflammatory effects of KI were not observed. Thus, the pharmacologic action of KI is based on its anti-inflammatory effects caused by the increase in IL-10 levels. This information would increase dermatologists' awareness of KI as an efficacious and cost-effective treatment.

Abstract
BACKGROUND The gold standard for diagnosis of cutaneous sporotrichosis involves the isolation of the fungus, Sporothrix, by a culture test. Generally, the sampling for the culture test is performed at the same time as skin biopsy under local anaesthesia. However, the culture test may occasionally return a false negative result. OBJECTIVE The aim of our study was to investigate the diagnostic value of a molecular method for diagnosing cutaneous sporotrichosis from formalin-fixed and paraffin-embedded (FFPE) tissues. METHODS Over a 30-year period, we collected 52 cases of cutaneous sporotrichosis from biopsied specimens that had been positively diagnosed by a culture test. A nested PCR specific for Sporothrix detection was applied using FFPE tissue as template. The results were compared with control samples from 79 patients diagnosed with other cutaneous diseases according to histopathological, clinical findings and a cutler test. RESULTS Of the 52 patients who were tested positive on the culture test, all cutaneous diseases were detected by PCR. Of the 59 patients in the control group, 58 tested negative by PCR. Under our conditions, the calculated sensitivity of this method was 100%, the specificity was 98.7% and the kappa coefficient was 0.984 (95% CI: 0.953-1.000). CONCLUSIONS The specific PCR assay used appears to be a useful tool for the prompt and accurate diagnosis of sporotrichosis. Using this method, it would be possible to diagnose cutaneous sporotrichosis for patients who were suspected of cutaneous sporotrichosis but tested negative on culturing, and for pathologically suspected cutaneous sporotrichosis patients for whom the culture test was not undertaken.

Abstract
AIM The objective of this study was to investigate the long-term oncological outcomes of minimally invasive radical hysterectomy (MIRH) for the treatment of early-stage cervical cancer retrospectively in the wake of the laparoscopic approach to cervical cancer (LACC) trial. METHODS A total of 109 patients with stage IA1 with lymphovascular space involvement, IA2, and IB1 cervical cancers were included in this study. The surgical and oncological outcomes were retrospectively evaluated. All patients underwent type C MIRH with a no-touch isolation technique for cervical tumor. RESULTS The median number of resected pelvic lymph nodes was 36 (range, 14-94), and 10 patients (9.2%) had positive nodes. One patient (0.9%) had positive surgical margins. Forty-six patients (42%) underwent adjuvant therapy. The median follow-up time was 73 months (range, 30-146 months). Five patients (4.6%) developed recurrent disease, and 3 patients (2.8%) died of cervical cancer. The 5-year disease-free survival and overall survival rates were 96.3% and 97.2%, respectively. A comparison between patients with tumor diameter ≤ 2 cm (n = 59) and those with tumor diameter > 2 cm (n = 50) did not identify any significant differences, with 5-year disease-free survival 96.6% versus 94.0% and 5-year overall survival 98.3% versus 96.0%, respectively. CONCLUSION In this retrospective study, MIRH with a no-touch isolation technique for stage IA to IB1 cervical cancer was a safe approach in terms of oncological outcomes. However, every surgeon who treats early-stage cervical cancer should inform each patient of the results of the LACC trial because it has an exceedingly high impact.

Abstract
Werner syndrome (WS) is an autosomal recessive disorder characterized by physical signs and symptoms, including premature aging and scleroderma-like skin changes. The gene responsible for WS is the WRN gene. A significant proportion of WS-related malignant tumours are non-epithelial types, and the incidence of oral squamous cell carcinoma (SCC) is rare. A case of oral SCC of the lower alveolus and gingiva arising in a 63-year-old woman with WS is reported here. Biopsy confirmed moderately differentiated SCC. Surgical resection was performed and there was no recurrence or metastasis at the 3-year follow-up. Mutation analysis using next-generation sequencing, detected no mutations in the genes encoding the molecules strongly involved in the development of oral SCC, such as TP53 or PIK3CA. No obvious mutations were detected. Based on the results of the study, the results of mutation analysis suggest that this case might be genetically different from the common mechanisms of SCC in the oral cavity.

Abstract
BACKGROUND Despite restoration of fertility after kidney transplantation, the benefit is limited in female kidney recipients. Our objective is to determine the reasons for this discrepancy. METHODS We evaluated 315 women who underwent kidney transplantation from 1983 to 2015 (a median of age at transplantation [10th-90th percentile] of 32 years [7-55 years]); 230 recipients between the ages of 15 to 49 years old as of March 2016 were observed. RESULTS We experienced 10 abortions and 21 live births from our 23 recipients and 2 abortions and 7 live births in 7 recipients from other transplant center. The live birth rate was 8.9 per 1000 female transplant recipients of childbearing age. Seven recipients received either treatments of artificial insemination or in vitro fertilization. Average age at pregnancy was 33.2 ± 3.2 years old, and the fertile period post-transplantation was longer in recipients with live births than those without live births (14.1 ± 7.1 vs 9.9 ± 7.3 years, P < .05). In 42.9% of recipients with live birth, pregnancy-induced hypertension was observed in the last trimester. The gestational age and the average birth weight were 32.8 ± 5.0 months and 2184 ± 632 g, respectively. During follow-up of 14.5 years, there was one case of graft loss, which is a rate of 2.5 per 1000 female recipients. CONCLUSION Although pregnancy complications are often observed in kidney recipients, graft survival is less influenced by pregnancy. Importantly, kidney disease at childbearing age disrupts pregnancy even after kidney transplantation.

Abstract
BACKGROUND The aim of this study was to assess the differences in pharmacokinetic (PK) profiles after the 1:1 ratio-based conversion from a twice-daily to a once-daily tacrolimus formulation (TD-TAC and OD-TAC, respectively) in pediatric recipients of kidney transplants. METHODS TD-TAC was initially administered to 29 pediatric patients who underwent kidney transplantations between April 2010 and September 2015 and were then subsequently switched to OD-TAC. The switch dose ratio was 1:1, and the 24-hour complete PK parameter assessment was performed before and after the regimen was changed from TD-TAC to OD-TAC. RESULTS The mean total daily dose at baseline was 5.5 ± 2.9 mg (0.18 ± 0.10 mg/kg body weight). Consecutive PK studies revealed no significant difference in the mean time to achieve maximum concentrations and the area under the concentration-time curve from 0 to 24 hours (AUC0-24) of both drug formulations. However, the mean trough concentration (Cmin) and the maximum concentration of OD-TAC were 22% and 6% lower and higher, respectively, than those of TD-TAC. Therefore, a better correlation was observed between the AUC0-24 and Cmin of OD-TAC than between those of TD-TAC. CONCLUSIONS After the change from TD-TAC to OD-TAC, the AUC0-24 values were equivalent despite a 22% reduction in Cmin. Cmin may therefore be an excellent predictor in the therapeutic drug monitoring of OD-TAC because of its superior correlation with AUC0-24.

Abstract
We experienced a case of bullous pemphigoid (BP) arising in juvenile hyaline fibromatosis (JHF) associated with oral squamous cell carcinoma (SCC). JHF is a very rare disease inherited in an autosomal recessive fashion. Skin-colored, elastic hard nodules up to 10 cm in size were scattered mainly on the trunk and scalp. Gingival hypertrophy and an ill-defined mass with an irregular surface on the hard palate were noticed. A skin biopsy and a gingival biopsy confirmed the diagnosis of JFH and oral SCC, respectively. The patient was receiving anti-cancer drugs for the treatment of oral SCC and the treatment was successful. In the meantime, bean to nail sized bullas were noticed on the hands and feet. Histological examination, immunofluorescence method and ELISA confirmed the diagnosis of BP. The pathophysiological mechanisms are discussed in the present case.

Abstract
Chromosomal and genomic instability due to telomere dysfunction is known to play an important role in carcinogenesis. To study telomere shortening in the epidermis surrounding actinic keratosis, we measured telomere lengths of basal, parabasal, and suprabasal cells in epidermis with actinic keratosis (actinic keratosis group, n = 18) and without actinic keratosis (sun-protected, n = 15, and sun-exposed, n = 13 groups) and in actinic keratosis itself as well as in dermal fibroblasts in the 3 groups, using quantitative fluorescence in situ hybridization. Among the 3 cell types, telomeres of basal cells were not always the longest, suggesting that tissue stem cells are not necessarily located among basal cells. Telomeres of basal cells in the sun-exposed group were shorter than those in the sun-protected group. Telomeres in the background of actinic keratosis and in actinic keratosis itself and those of fibroblasts in actinic keratosis were significantly shorter than those in the controls. Our findings demonstrate that sun exposure induces telomere shortening and that actinic keratosis arises from epidermis with shorter telomeres despite the absence of any histologic atypia.

Abstract
Aortic regurgitation in association with aortic stenosis is rare in the fetus. Findings have shown that severe aortic regurgitation is worsened by the increase in systemic vascular resistance after birth, resulting in low cardiac output, hypoxemia, and neonatal death. This report describes a unique case of aortic regurgitation with aortic stenosis, severe mitral regurgitation, retrograde flow in the aortic arch, and an enormous left atrium with a restrictive foramen ovale in a fetus. In this case, aortic regurgitation was diminished immediately after birth, indicating that spontaneous improvement in aortic regurgitation after birth should be taken into account when the final prognosis is predicted.

Abstract
BACKGROUND Interleukin (IL) 33, a novel member of the IL-1 family, is produced mainly by epithelial cells and endothelial cells in response to various types of stress, including necrosis. The effects of IL-33 on the immune cells involved in allergic contact dermatitis have recently been revealed in vitro. However, in vivo, the induction mechanism and function of IL-33 are not fully understood. OBJECTIVES Our objectives were to investigate induction of IL-33 in keratinocytes and to evaluate the functions of IL-33 and its inducers in a murine model of allergic contact dermatitis. MATERIAL AND METHODS KERTr cells, a human keratinocyte cell line, were cultured with various cytokines, including tumor necrosis factor (TNF) alpha and interferon (IFN) gamma. IL-33 expression was detected using quantitative reverse transcriptase polymerase chain reaction, immunocytochemistry, and Western blotting. The functions of IL-33, TNF-a, and IFN-y in allergic contact dermatitis were evaluated using a murine model. RESULTS TNF-alpha and IFN-gamma induced expression of IL-33 mRNA and protein in KERTr cells. Blockade of IL-33 attenuated swelling in the ears of the experimental mice. Similar effects were noted for blockade of TNF-alpha and IFN-gamma in these mice. CONCLUSIONS TNF-alpha and IFN-gamma induce expression of IL-33, and IL-33 produced by keratinocytes contributes to allergic contact dermatitis. Blockade of IL-33, TNF-alpha, and IFN-gamma could represent novel and potent strategies to treat allergic contact dermatitis.

Abstract
BACKGROUND Recent studies have demonstrated that systemic or topical PUVA therapy, i.e., ultraviolet A (UVA) irradiation following treatment with 8-methoxypsoralen (8-MOP), is effective against the sclerotic skin lesions in systemic sclerosis. However, the mechanisms still remain unknown. OBJECTIVE To clarify the mechanisms of this therapy, we created a mouse model of bleomycin (BLM) injection-induced scleroderma and evaluated the effects of PUVA on the fibrotic lesions of scleroderma in this mouse model. METHODS BLM was injected subcutaneously once a day into the mice for 24 days. During the injection period, one group of mice was irradiated with UVA following local application of 8-MOP. Control groups were also set up, which were injected with phosphate-buffered saline, instead of BLM. Skin tissue samples examined histopathologically changes, measured of the content of hydroxyproline, and checked for the expression of genes encoding type I collagen, type III collagen, and transforming growth factor-β1 (TGF-β1). RESULTS The mouse models of scleroderma was found to show an increase in the density of the collagen fibers and thickening of the dermis and increased expressions of type I collagen, type III collagen, and TGF-β1. However, the combination of BLM treatment and topical PUVA treatment mice appeared reduced the dermal thickness and hydroxyproline content, down-regulation of expressions of the type I and type III collagen genes was observed while the expression of the TGF-β1 gene remained unchanged. CONCLUSION These results suggest that the effectiveness of topical PUVA therapy is attributable to the down-regulation of the expressions of the collagen genes by this treatment. The results additionally suggest that is not mediated by down-regulated expression of the TGF-β1.
