Abstract
BACKGROUND Epidermolytic ichthyosis (EI) is a major form of nonsyndromic inherited ichthyosis, characterized by erythroderma, marked hyperkeratosis and scale, bulla and erosion at birth, associated with KRT1/KRT10 mutations. The cytokine and chemokine profiles in EI are poorly understood, and specific treatment options have not been established. AIM To explore novel biomarkers and therapeutic targets in patients with EI. METHODS We analysed cytokine levels in serum and skin samples from 10 patients with inherited ichthyosis, including seven patients with EI. Wild-type and mutant KRT1 constructs were established and transfected into HaCaT cells, an immortalized keratinocyte cell line, for in vitro immunoblotting and immunocytochemistry analyses. RESULTS Multiplex cytokine/chemokine analysis revealed that 10 cytokines/chemokines [interleukin (IL)-1β, IL-4, IL-17A, IL-16, IL-18, IL-1 receptor-α, macrophage colony-stimulating factor, interferon-α2, basic fibroblast growth factor and monocyte chemotactic protein-3] were significantly increased in patients with EI. Furthermore, IL-18 levels were significantly higher in patients with EI [n = 7; 2714.1 (1438.0) pg mL-1] than in healthy controls [n = 11; 218.4 (28.4) pg mL-1, P < 0.01]. Immunohistochemical analyses showed that IL-18 expression was elevated in skin samples from patients with EI. Serum IL-18 levels correlated with the severity of ichthyosis, as measured by the Ichthyosis Scoring System. Immunoblotting analysis revealed that mature IL-18 levels were increased in the supernatant of mutant KRT1 expressing HaCaT cells. Additionally, these cells showed NLRP3 aggregation in the cytoplasm and ASC clustered around mutant keratin aggregations. These findings suggest that mutant keratin might promote the activation of the NLRP3 inflammasome and its downstream caspase-1-mediated IL-18 release in keratinocytes from patients with EI. CONCLUSIONS Our results suggest that serum IL-18 is a severity marker released from the skin of patients with EI. Blockade of IL-18 may be a useful novel therapeutic option for patients with EI.

Abstract
Hailey-Hailey disease (HHD) is a rare autosomal dominant acantholytic dermatosis clinically characterized by recurrent erythematous plaques and erosions mainly on the intertriginous regions. Although HHD seriously affects quality of life, conventional treatments often fail to provide long-term relief for most patients. The effectiveness of apremilast, a phosphodiesterase-4 inhibitor, against severe HHD was first reported in 2018, and after further testing, this agent is currently expected to be established as an efficacious and safe therapeutic option. Here we report two cases of HHD treated with apremilast which showed opposite outcomes. Although the case with extremely severe symptoms showed remarkable and long-lasting improvement with apremilast used after acute treatment with oral corticosteroid, the other case, with milder symptoms treated only with apremilast, showed no improvement. Our transcriptome analysis using skin samples collected prior to apremilast administration revealed the involvement of the NF-κB signaling pathway, which is related to the responses to bacteria and other organisms. However, this pathway was more strongly activated in case 2 than in case 1, suggesting that the steroid treatment preceding apremilast may have been effective and supportive in the apremilast-responding case. One of the two cases highlights the potential of apremilast as a treatment option for HHD, but the other underlines the difficulties in managing HHD and the complexity of the disease background. The accumulation of cases and larger clinical studies are expected to precisely evaluate the safety and efficacy of apremilast, and the potential for therapies in combination with conventional treatments.

Abstract
Carotenoderma is a yellow-orange coloration of the skin caused by high levels of serum carotenoids, mostly due to the excessive intake of carotenoid-rich foods. The yellowish coloration is typically observed on the palms, soles, and nasolabial folds. Although the physical appearance is prominent, the condition itself is benign and harmless. Diagnosing carotenoderma is not difficult because of its unique manifestations, but its pathophysiology remains unclear. We report a relatively rare case of carotenoderma due to lycopenemia caused by the excessive intake of lycopene-rich vegetables and fruits. Lycopene is a carotenoid component that is distinguished by the high absorption of light around 488 nm. Given these characteristics, we examined a hematoxylin-eosin-stained specimen from the patient and tape-stripped samples by fluorescent microscopy with 488 nm wavelength emission and compared them with normal skin samples. Notably, the patient's samples showed a weaker autofluorescence in the stratum corneum and sweat glands. Furthermore, we measured carotenoid concentrations in the patient's skin noninvasively with Vegecheck® and found a higher score than the average of 24 healthy volunteers. These results support the long-held hypothesis that carotenoids are secreted in sweat and are deposited in the stratum corneum. To the best of our knowledge, no previous reports have measured skin carotenoid levels nor detailed the pathological findings of carotenoderma patients. This case further highlights that the excessive intake of lycopene causes carotenoderma and demonstrates that carotenoid deposition is particularly pronounced in the stratum corneum of the skin.

Objectives
Angiopoietin-like protein 2 (ANGPTL2) is a protein, whose structure is similar to that of angiopoietin, but binds to a different receptor. Overexpression of ANGPTL2 promotes chronic inflammation and relates to the development of aging-related diseases. ANGPTL2 has been reported to be mainly secreted by adipose tissue. Although ANGPTL2 has been implicated in the pathogenesis of heart failure, there are no studies about serum ANGPTL2 levels in patients with heart failure participating in cardiac rehabilitation program. The aim of this study was to investigate the characteristics, related factors and changes of ANGPTL2 in patients with chronic heart failure during phase III of cardiac rehabilitation program.
Methods
The subjects included 57 patients (70.1 ± 10.2 years old; 46 men) with chronic heart failure whose serum ANGPTL2 levels were measured during the maintenance phase of cardiac rehabilitation program. Furthermore, we classified 25 patients (70.6 ± 7.5 years old; 23 men) from the 6-month course into a reduced group and an unchanged group to characterize change in ANGPTL2. We excluded patients who were admitted or discharged within 3 months of the evaluation of serum ANGPTL2. We evaluated exercise tolerance using the cardiopulmonary exercise test, grip strength, body composition using a body composition analyzer, blood examinations, and echocardiography. Serum ANGPTL2 was measured by solid-phase sandwich enzyme-linked immunosorbent assay (ELISA).
Results
The median value of ANGPTL2 was 4.05 ng/ml. ANGPTL2 was positively correlated with body weight, body mass index, body fat mass, body fat percentage, C-reactive protein (CRP) and total protein (TP) levels, and negatively correlated with skeletal muscle mass percentage and anaerobic threshold (AT). From the result of the logistic regression analysis, AT (OR=0.68, 95% CI:0.47-0.97and TP (OR=20.1, 95% CI:2.52-160.63) were extracted as independent factors related to the level of ANGPTL2. In addition, overall serum ANGPTL2 levels decreased significantly after 6 months. Changes in ANGPTL2 in the reduced group showed a positive correlation between baseline peak VO2, left ventricular ejection fraction and skeletal muscle rate, and a negative correlation with baseline ANGPTL2, CRP, body fat mass. In an unchanged group, HbA1c increased, but no significant change was observed in other factors.
Conclusions
Exercise tolerance in patients with chronic heart failure during maintenance phase might be related to the inflammation marker ANGPTL2. Serum ANGPTL2 levels with stable chronic heart failure patients decreased significantly 6 months after continued cardiac rehabilitation.

Abstract
Background: Hereditary fibrosing poikiloderma with tendon contractures, myopathy, and pulmonary fibrosis (POIKTMP) is an extremely rare disease caused by mutations in FAM111B, and only approximately 30 cases have been reported worldwide. Some patients develop interstitial pneumonia, which may lead to progressive pulmonary fibrosis and poor prognosis. However, no effective treatment for interstitial pneumonia associated with POIKTMP has been reported. Here, we report an autopsy case of POIKTMP, wherein interstitial pneumonia was improved by corticosteroids. Case Presentation: A 44-year-old Japanese man was referred to our hospital due to poikiloderma, hypotrichosis, and interstitial pneumonia. He developed progressive poikiloderma and muscle weakness since infancy. He also had tendon contractures, short stature, liver cirrhosis, and interstitial pneumonia. Mutation analysis of FAM111B revealed a novel and de novo heterozygous missense mutation, c.1886T > G (p(Phe629Cys)), through which we were able to diagnose the patient with POIKTMP. 3 years after the POIKTMP diagnosis, interstitial pneumonia had worsened. After 2 weeks of administrating 40 mg/day of prednisolone, his symptoms and lung shadows improved. However, he subsequently developed severe hepatic encephalopathy and eventually died of respiratory failure due to bacterial pneumonia and pulmonary edema. Autopsy revealed an unclassifiable pattern of interstitial pneumonia, as well as the presence of fibrosis and fatty degeneration in several organs, including the liver, kidney, skeletal muscle, heart, pancreas, and thyroid. Conclusions: We report a case of POIKTMP in which interstitial pneumonia was improved by corticosteroids, suggesting that corticosteroids could be an option for the treatment of interstitial pneumonia associated with this disease.

Abstract
We report 2 generalized verrucosis (GV) patients homozygous for a novel mutation in the start codon of IL7. Unlike the previous report in which IL-7 deficiency accompanied CD4 T lymphocytopenia, circulating CD4 T cells were not depleted in one of our patients, suggesting a GV pathogenesis other than poor T-cell development.

Abstract
We demonstrate that revertant mosaicism frequently occurs in loricrin keratoderma and that somatic recombination is the major mechanism underlying this therapeutically important phenomenon. Revertant mosaicism is a phenomenon in which pathogenic mutations are rescued by somatic events, representing a form of natural gene therapy. Here, we report on the first evidence for revertant mosaicism in loricrin keratoderma (LK), an autosomal dominant form of ichthyosis caused by mutations in LOR on 1q21.3. We identified two unrelated LK families exhibiting dozens of previously unreported white spots, which increased in both number and size with age. Biopsies of these spots revealed that they had normal histology and that causal LOR mutations were lost. Notably, dense single nucleotide polymorphism mapping identified independent copy-neutral loss-of-heterozygosity events on chromosome 1q extending from regions centromeric to LOR to the telomere in all investigated spots, suggesting that somatic recombination represents a common reversion mechanism in LK. Furthermore, we demonstrated that reversion of LOR mutations confers a growth advantage to cells in vitro, but the clinically limited size of revertant spots suggests the existence of mechanisms constraining revertant clone expansion. Nevertheless, the identification of revertant mosaicism in LK might pave the way for revertant therapy for this intractable disease.

Abstract
BACKGROUND Mucous membrane pemphigoid (MMP) is a rare chronic autoimmune subepithelial blistering disorder, targeting multiple basement membrane zone (BMZ) proteins including collagen XVII (COL17). Circulating autoantibodies of MMP are often undetected due to their lower titers. The oral mucosa is a valuable substrate for the detection of autoantibodies in MMP patients. However, obtaining normal human oral mucosa is more difficult than obtaining normal human skin. We established immortalized normal human oral mucosal keratinocytes (OMKs) and performed immunoblotting using immortalized OMK lysate for detecting autoantigens in MMP. METHODS Immortalized OMKs were generated from primary OMKs using E6/E7 proteins of HPV. We compared the protein expression levels of major BMZ proteins between primary OMKs and immortalized OMKs. We performed immunoblotting to detect autoantigens using cell lysates from immortalized OMKs in 30 MMP patients. RESULTS There were no significant differences between primary OMKs and immortalized OMKs in terms of protein expression levels of the BMZ proteins, including COL17, laminin 332, integrin α6/β4, collagen VII, and collagen IV. Cell lysates of immortalized OMKs effectively identified MMP autoantigens in 60% (18/30) of MMP sera. We found an interesting case of MMP whose autoantibodies preferentially reacted to the 120-kD protein that is an ectodomain of COL17. CONCLUSION We demonstrated that a cell lysate of immortalized OMKs is a reliable substrate for the detection of MMP autoantigens. This newly developed immunoblotting analysis method promises to contribute to the diagnosis of MMP.

Abstract
TGM1 is the most common gene responsible for lamellar ichthyosis. Previous studies have suggested that patients with lamellar ichthyosis carrying two missense mutations in TGM1 show significantly less severe phenotypes than those with at least one truncating mutation in TGM1. Here, we report a patient with severe lamellar ichthyosis who was compound heterozygous for TGM1 missense mutations, including a novel one. A 22-year-old Japanese man presented with large, dark brown, plate-like scales on the extremities and small adherent scales on the face and trunk. His other clinical findings included ectropion, hair loss, hypohidrosis, hyperthermia in summer, palmoplantar keratoderma and constriction of the fingers. Dermoscopy revealed accentuated sulci cutis with numerous large keratotic plugs in the cristae cutis. Histologically, orthohyperkeratosis and mild acanthosis were noted. Electron microscopy showed reduced cornified envelope thickness and numerous lipid droplets in the stratum corneum. Mutation analysis revealed the patient to be compound heterozygous for missense mutations, c.620T>C (p.Leu207Pro) and c.1631A>G (p.Tyr544Cys), in TGM1. Furthermore, we showed that TGM1 enzymatic activity was largely absent in his epidermis. These findings led us to diagnose him as having lamellar ichthyosis. This study has two important notions. First, even two missense mutations in TGM1 can cause severe lamellar ichthyosis. Second, this is the first report of dermoscopic findings of lamellar ichthyosis, implicating the obstruction of sweat glands by keratotic plugs in the pathogenesis of hypohidrosis in the disease. In conclusion, this study provides further insights into genotype-phenotype correlations and pathogenesis in lamellar ichthyosis.

Abstract
Acquired dermal melanocytosis of the face and extremities (ADMFE) is an unusual form of acquired dermal melanocytosis (ADM). In this paper, we report a case of ADMFE and review the published literature. Our review highlights several clinical differences between ADMFE and ADM: (i) more frequent involvement of the nasal alae in ADMFE than in ADM, (ii) less frequent involvement of the cheeks in ADMFE than in ADM, (iii) limbs affected in all cases of ADMFE but in few cases of ADM, and (iv) frequent involvement of conjunctiva and/or gingiva in ADMFE but very rare involvement in ADM. These findings strongly support the hypothesis that ADMFE is clinically distinct from the classic form of ADM, and gaining an understanding of its phenotype will enable accurate diagnosis and early intervention by Q-switched laser therapy, which should benefit those patients with disease-related cosmetic issues.

Abstract
Arterial compliance (AC) is an index of the elasticity of large arteries. Endothelial dysfunction has been reported to result in reduced arterial compliance, which represents increased arterial stiffness. A reduction in AC is elicited by high-intensity resistance training, however the mechanisms are obscure. Because a single bout of resistance exercise causes a transient increase in circulating plasma endothelin-1 in humans, some vasoconstrictors may play a role in the mechanisms. The present study aimed to investigate whether resistance training-induced decrease in AC is associated with changes in circulating vasoconstrictors levels in young men. Young sedentary men were assigned to control (n=5) or training (n=9) groups. The training group performed four-week high-intensity resistance training (weight training exercise; three sessions/week). We measured AC and plasma levels of endothelin-1, angiotensin II, and norepinephrine before and after intervention. Resistance training significantly decreased AC, whereas the changes in plasma levels of neither endothelin-1, nor angiotensin II, nor norepinephrine were significantly different between the control and the training groups. Moreover, we found no significant correlations between changes in circulating plasma levels (endothelin-1, angiotensin II, and norepinephrine) and in the AC. Despite of no alteration of the resting circulating plasma levels (endothelin-1, etc.), we cannot exclude a possibility that the tissue/local concentrations of vasoconstrictors (endothelin-1, etc.) around the vessels might be increased and also involved in a reduction of AC in the training group. Taken together, the present results suggest that circulating vasoconstrictors (endothelin-1, etc.) in plasma are not involved in a reduction in AC by the resistance training.

Abstract
Heterozygous chromosomal inversions suppress recombination. Therefore, they may potentially influence recombination-associated phenotypes of human diseases, but no studies have verified this hypothesis. Here, we describe a 35-year-old man with severe congenital ichthyosis. Mutation analysis revealed a heterozygous splice-site mutation, c.1374-2A>G (p.Ser458Argfs*120), in KRT10 on 17q21.2. This mutation was previously reported in patients with ichthyosis with confetti type I (IWC-I), a prominent skin disease characterized by the frequent occurrence of recombination-induced reversion of pathogenic mutations. Intriguingly, the number of revertant skin areas in this patient is considerably reduced compared with typical IWC-I cases. G-banded karyotyping revealed that the patient harbors a heterozygous nonpathogenic inversion, inv(17)(p13q12), whose long-arm breakpoint was subsequently refined to chromosomal positions (chr17: 36,544,407-36,639,830) via FISH. Collectively, the only chance of revertant mosaicism through somatic recombination appears to involve recombination between the KRT10 mutation and the inversion breakpoint. Indeed, in the examined revertant spot, the KRT10 mutation was diminished by somatic recombination starting from chromosomal positions (chr17: 36,915,505-37,060,285) on 17q12. This study provides the first evidence to our knowledge implicating chromosomal inversions as a potential modifier of clinical phenotypes. Furthermore, the reduced occurrence of revertant spots in the recombination-suppressed patient suggests that somatic recombination is the main mechanism of revertant mosaicism in IWC-I.

Abstract
Nagashima-type palmoplantar keratosis (NPPK) is an autosomal recessive skin disorder with a high, unmet medical need that is caused by mutations in SERPINB7. Almost all NPPK patients carry the founder nonsense mutation c.796C>T (p.Arg266Ter) in the last exon of SERPINB7. Here we sought to determine whether topical nonsense-suppression (readthrough) therapy using gentamicin is applicable to NPPK. First, we demonstrated that gentamicin enhanced readthrough activity in cells transfected with SERPINB7 cDNA carrying the mutation and promoted full-length SERPINB7 protein synthesis in NPPK keratinocytes. We next conducted an investigator-blinded, randomized, bilaterally controlled compassionate use study of topical gentamicin in which five NPPK patients with c.796C>T were enrolled. Patients' self-reported improvement of hyperkeratosis was significantly greater on the gentamicin side than the control side (P = 0.0349). In two patients, hyperkeratosis was improved on the gentamicin side, as determined by a blinded-investigator assessment. These results indicate the therapeutic potential of topical gentamicin for NPPK. Unexpectedly, we also found that mutant SERPINB7 mRNAs harboring r.796c>u were degraded by nonsense-mediated mRNA decay. Furthermore, the truncated SERPINB7 protein was degraded via a proteasome-mediated pathway. These findings provide important insights into the mRNA/protein quality-control system in humans, which could be a potential therapeutic target for genetic diseases.

Abstract
PURPOSE The aim of this study was to investigate the efficacy of prone-position computed tomography (CT) for detecting and classifying inguinal hernia relative to supine-position CT before laparoscopic inguinal hernia repair. METHODS Seventy-nine patients who underwent laparoscopic transabdominal preperitoneal repair of inguinal hernia were enrolled in this prospective study. Patients diagnosed with inguinal hernia by physical examination underwent abdominal CT in the supine and prone positions for preoperative assessment. The anatomy of the right and left inguinal regions was confirmed during the surgery and compared with the preoperative CT findings. RESULTS The 79 cases included 87 operated lesions and 71 non-operated contralateral inguinal sites. Of the 84 clinical hernias, inguinal hernia was detected significantly more frequently on prone-position CT images (84, 100%) than on supine-position CT images (55, 65.5%). In addition, the inguinal hernia type was determined with significantly greater accuracy on prone-position CT images (96.4%) than on supine-position CT images (58.3%). Twenty-two occult hernias were detected by laparoscopy. The detection rate and accuracy for determining the type of occult hernia were significantly greater when using prone-position CT images [19 of 22 lesions (86.4%) and 77.3%, respectively] than when using supine-position CT images [8 of 22 lesions (36.4%) and 27.3%, respectively]. CONCLUSIONS Prone-position CT is adequate for detecting and classifying inguinal hernia and for evaluating occult hernia.

Abstract
Liver ischemia reperfusion injury (IRI) is an important problem in liver transplantation. Thrombomodulin (TM), an effective drug for disseminated intravascular coagulation, is also known to exhibit an anti-inflammatory effect through binding to the high-mobility group box 1 protein (HMGB-1) known as a proinflammatory mediator. We examined the effect of recombinant human TM (rTM) on a partial warm hepatic IRI model in wild-type (WT) and toll-like receptor 4 (TLR-4) KO mice focusing on the HMGB-1/TLR-4 axis. As in vitro experiments, peritoneal macrophages were stimulated with recombinant HMGB-1 protein. The rTM showed a protective effect on liver IRI. The rTM diminished the downstream signals of TLR-4 and also HMGB-1 expression in liver cells, as well as release of HMGB-1 from the liver. Interestingly, neither rTM treatment in vivo nor HMGB-1 treatment in vitro showed any effect on TLR-4 KO mice. Parallel in vitro studies have confirmed that rTM interfered with the interaction between HMGB-1 and TLR-4. Furthermore, the recombinant N-terminal lectin-like domain 1 (D1) subunit of TM (rTMD1) also ameliorated liver IRI to the same extent as whole rTM. Not only rTM but also rTMD1 might be a novel and useful medicine for liver transplantation. This is the first report clarifying that rTM ameliorates inflammation such as IRI in a TLR-4 pathway-dependent manner.

Abstract
BACKGROUND We evaluated the efficacy and safety of superselective embolization with assistance of colonoscopy for acute colonic hemorrhage. METHODS Of 92 cases of acute colonic hemorrhage requiring colonoscopic intervention, 11 (12 %) could not be successfully treated. Of these, 10 patients (9 men, mean age 65.5 years, range 39-75 years) underwent superselective embolization. Hemorrhage was caused by diverticular disease (n = 8), polypectomy (n = 1), and vascular malformation (n = 1). In all 10 cases, the radiopaque clips were placed at the bleeding point via colonoscopy. Microcatheters were used in all procedures, and embolization was performed at the level of the vasa recta leading to or near the clips with Gelfoam particles, microcoils, or both. RESULTS Immediate hemostasis was achieved in all patients. In 6 of 10 patients (60 %), selective angiograms showed no active extravasation at the time of the procedure and the embolization was performed using clips as a landmark. In the remaining four patients, selective angiograms showed active extravasation from the vasa recta leading to the clips. The mean number of embolized vessels with no active extravasation and with active extravasation was 1.83 (range 1-3) and 1.25 (range 1-2), respectively. The mean duration of clinical follow-up was 11.6 months (range 1-29 months). One patient (10 %) bled from a different site than the treated site a month after embolization, but the bleeding ceased after endoscopic intervention. All the patients (100 %) were evaluated for objective evidence of ischemia by colonoscopy. Four of the 10 patients (40 %) were found endoscopically to have small areas of ischemia involving only the mucosa, but they remained asymptomatic. There was no bowel infarction or stricture. CONCLUSIONS Colonoscopy-assisted superselective embolization may be a safe and useful procedure for acute colonic hemorrhage without active extravasation on angiogram.
