抄録 Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is a promising method for controlling tumors, although it does not entirely eliminate recurrence. Oxidative stress is associated with the progression of hepatocarcinogenesis, while also acting as an anticancer response. The objective of the present study was to investigate the factors influencing post-RFA outcomes. We recruited 235 newly diagnosed HCC patients who received RFA for single tumors. The patients with recurrence were sub-grouped into early and segmental recurrence groups. The characteristics of the sub-grouped patients were evaluated, including by measuring oxidative stress marker reactive oxygen metabolites and antioxidant marker OXY-adsorbent tests. The factors associated with poor survival were a high Child-Pugh score and early recurrence within 2 years in the same segment. The patients who experienced recurrence within 2 years in the same segment showed a larger tumor diameter than did others. According to a multivariate analysis, the OXY values were also significantly low in these patients. In conclusion, maintaining the antioxidant reservoir function with a high OXY value might be necessary to prevent early recurrence within the RFA-treated segment.

抄録 The importance of centralizing treatment services for severely ill children has been well established, but such entralization remains difficult in Japan. We aimed to compare the trauma and illness severity and mortality of children admitted to two common types of ICUs for children. According to the type of management and disposition of the medical provider, we classified ICUs as pediatric ICUs [PICUs] or general ICUs, and analyzed differences in endogenous and exogenous illness settings between them. Overall, 1,333 pediatric patients were included, with 1,143 patients admitted to PICUs and 190 patients to general ICUs. The Pediatric Cerebral Performance Category score (PCPC) at discharge was significantly lower in the PICU group (adjusted OR: 0.45; 95%CI: 0.23-0.88). Death and unfavorable neurological outcomes occurred less often in the PICU group (adjusted OR: 0.29; 95%CI: 0.14-0.60). However, when limited to exogenous illness, PCPC scores (adjusted OR: 0.38; 95%CI: 0.07-1.99) or death/unfavorable outcomes (adjusted OR: 0.72; 95%CI: 0.08-6.34) did not differ between the groups. PCPC deterioration and overall sequelae/death rates were lower in PICUs for children with endogenous illnesses, although the outcomes of exogenous illness were similar between the 2 unit types. Further studies on the necessity of centralization are warranted.

抄録 In this retrospective single-center cohort study, we investigated the impact of preoperative use of an alpha-1 adrenergic receptor (AR) blocker on the outcome of single-session extracorporeal shock wave lithotripsy (SWL) in 193 male patients who underwent SWL for a single ureteral calculus between 2006 and 2016. We reviewed their medical records to obtain the data on the preoperative use of alpha-1 AR blockers. The primary outcome was treatment success after single-session SWL. We performed a multivariable logistic regression analysis adjusting for clinically important confounders to examine the association between preoperative use of alpha-1 AR blockers and the treatment success of SWL. Among the 193 patients, 15 (7.8%) were taking an alpha-1 AR blocker preoperatively. A multivariable analysis showed that preoperative use of an alpha-1 AR blocker was a significant negative predictor for treatment success of SWL (adjusted odds ratio 0.17; 95% confidence intervals, 0.04-0.74). Our findings suggest that the preoperative use of an alpha-1 AR blocker was a negative predictor of treatment success of SWL in male patients with a single ureteral calculus. Clinicians should pay more attention to the preoperative drug use in determining an appropriate stone therapy modality.

抄録 Ketamine has been clinically proven to ameliorate depression, including treatment-resistant depression. The detailed mechanism of action of ketamine in treatment-resistant depression remains unclear. We examined the effects of ketamine on the immobility times of adrenocorticotropic hormone (ACTH)-treated rats during the forced swim test, and we explored the mechanism by which ketamine acts in this model. We investigated the neuroanatomical site of action by microinjecting ketamine into the medial prefrontal cortex of rats. A significant reduction of the rats’ immobility during the forced swim test was observed after the intraperitoneal injection of ketamine in both saline- and ACTH-treated rats. The microinjection of ketamine into the medial prefrontal cortex also decreased immobility during the forced swim test in both saline- and ACTH-treated rats. The immobility-decreasing effect of intraperitoneally injected ketamine was blocked by administering WAY100635, a 5-HT1A receptor antagonist, into the medial prefrontal cortex. These findings contribute to the evidence that ketamine can be useful against treatment-resistant depressive conditions. The immobility-reducing effects of ketamine might be mediated by 5-HT1A receptor activity in the medial prefrontal cortex.

抄録 We examined the effect of D-Tagatose on the growth of oral bacteria including Streptococcus mutans (S. mutans). Saliva collected from 10 healthy volunteers was plated on BHI medium (to culture total oral bacteria) and MBS medium (to culture S. mutans, specifically). Agar plates of BHI or MBS containing xylitol or D-Tagatose were cultured under aerobic or anaerobic conditions. We then counted the number of colonies. In BHI plates containing D-Tagatose, a complete and significant reduction of bacteria occurred under both aerobic and anaerobic conditions. In MSB medium, significant reduction of S. mutans was also observed. We then performed a doubleblind parallel randomized trial with 19 healthy volunteers. They chewed gum containing xylitol, D-Tagatose, or both for 4 weeks, and their saliva was collected weekly and plated on BHI and MSB media. These plates were cultured under anaerobic conditions. Total bacteria and S. mutans were not effectively reduced in either the D-Tagatose or xylitol gum group. However, S. mutans was significantly reduced in volunteers chewing gum containing both D-Tagatose and xylitol. Thus, D-Tagatose inhibited the growth of S. mutans and many types of oral bacteria, indicating that D-Tagatose intake may help prevent dental caries, periodontitis, and many oral diseases.

抄録 Differentiated thyroid carcinoma (DTC) in juvenile patients is often an extensive and aggressive disease with a high frequency of recurrence. However, the prognosis is excellent, with a low mortality rate even when advanced disease is present, although prognostic factors and treatment strategy remain uncertain. Between April 2004 and March 2017, 33 juvenile patients (< 30 years old) were diagnosed with DTC and treated at our institution. We retrospectively investigated prognosis and factors including sex, reason for discovery, treatment, pathological factors and treatment progress to clarify the risk factors. All patients underwent curative surgical treatment. Pathologically, lymph node metastasis was identified in 25 patients (75%). Thirteen patients (39%) had bilateral cervical metastasis. In addition, 9 (27%) had more than 10 metastatic lymph nodes. The 2 patients with more than 20 metastatic lymph nodes were treated with radioactive iodine (RAI). Five patients (15%) had local recurrences and received surgery. There have been no further recurrences or deaths. However, no factors were determined to significantly predict the recurrence of juvenile DTC. Local recurrent disease was treated with surgery and/or RAI until remission, and survival was excellent in juvenile DTC.

抄録 The prognosis of advanced non-small cell lung cancer (NSCLC) patients has improved in recent decades, especially for patients with an oncogenic driver mutation. Anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) are effective for patients with the echinoderm microtubule-associated protein-like 4-ALK fusion gene. Several ALK-TKIs have been established: the first-generation ALK-TKI, crizotinib; second-generation ALK-TKIs, alectinib and ceritinib; and third-generation ALK-TKI, lorlatinib. Some ALK-TKIs are effective for tumors that are resistant to other ALK-TKIs; however, as is known in epidermal growth factor receptormutant lung cancer, tumor resistance is inevitable. ALK-positive NSCLCs acquire resistance via various mechanisms, making it a heterogeneous disease. Therefore, it is necessary to develop next-generation treatment strategies, such as the use of next-generation ALK-TKIs for secondary mutations, or combination therapies with ALK-TKIs and other TKIs. In this review, we summarize the development and use of ALK-TKIs, prior pivotal clinical trials, and resistance mechanisms.

抄録 To clarify the relevance of prolactin (PRL) to clinical parameters in patients who visited our general medicine department, medical records of 353 patients in whom serum PRL levels were measured during the period from 2016 to 2018 were retrospectively reviewed. Data for 140 patients (M/F: 42/98) were analyzed after excluding patients lacking detailed records and patients taking dopaminergic agents. Median serum PRL levels were significantly lower in males than females: 6.5 ng/ml (IQR: 4.2-10.3) versus 8.1 ng/ml (5.9-12.9), respectively. Pain and general fatigue were the major symptoms at the first visit, and past histories of hypertension and dyslipidemia were frequent. Male patients with relatively high PRL levels (≥ 10 ng/ml) had significantly lower levels of serum albumin and significantly higher levels of serum LDH than those with low PRL (< 10 ng/ml). There were significant correlations of male PRL level with the erythrocyte sedimentation rate (R=0.62), serum LDH level (R=0.39) and serum albumin level (R=−0.52), while the level of serum CRP (R=0.33) showed an insignificant but weak positive correlation with PRL level. Collectively, these results show that PRL levels had gender-specific relevance to various clinical factors, with PRL levels in males being significantly related to inflammatory status.

抄録 Indexes for objectively evaluating abnormal gait in hip osteoarthritis (OA) patients and determining effective interventions are unclear. We analyzed the abnormal gait of hip OA patients by focusing on movements of the trunk and pelvis to establish an effective evaluation index for each direction of motion. We studied 28 patients with secondary hip OA due to developmental dysplasia of the hip and 16 controls. The trunk and pelvic movements during gait were measured in the medial-lateral (x), vertical (y), and back-and-forth (z) directions by a triaxial angular accelerometer. Gait speed, steps, step length, muscle strength, range of motion, and timed up-and-go (TUG) test performance were measured. We determined the correlations between physical function and the index of abnormal gait in the hip OA patients. Movements other than trunk and pelvic motions in the y-direction indicated abnormal gait in the patients. Significant correlations were found between abnormal gait and range of motions (extension, internal rotation), TUG score, stride length, and steps. The TUG test, stride length and steps were important for evaluating abnormal gait in hip OA patients. Individual interventions for each movement direction are required.

抄録 Endoscopic submucosal dissection (ESD) has become the first-line treatment for early gastric neoplasms; however, a subset of patients treated by this method develop aspiration pneumonia. We conducted a comprehensive prospective analysis of the factors contributing to post-ESD aspiration pneumonia in early gastric neoplasms in this study, with special focus on whether pre-treatment oral care can prevent aspiration pneumonia. Sixty-one patients who underwent ESD for gastric neoplasms were randomly assigned to the oral care or control groups. ESD was performed under deep sedation. Of 60 patients whose data were available for analysis, 5 (8.3%) experienced pneumonia confirmed either by chest radiography or computed tomography. Although no difference in the rate of pneumonia was found between the control and oral care groups, the post-oral care bacteria count was significantly higher in the saliva of patients who developed pneumonia compared to those without pneumonia. In addition, the presence of vascular brain diseases and the dose of meperidine were also significantly associated with the occurrence of pneumonia. These results suggest that the number of oral bacteria as well as pre-existing vascular brain diseases and high-dose narcotics can affect the incidence of post-ESD pneumonia.

抄録 During radiation therapy, incident radiation oblique to the skin surface is high and may cause severe skin damage. Understanding the dose of radiation absorbed by the skin is important for predicting skin damage due to radiation. In this study, we used a high-energy (4 MV) X-ray system and an optically stimulated luminescence dosimeter (OSLD) that was developed for personal exposure dosimetry. We determined the dose variation and angular dependence, which are the characteristics of a small OSLD required to derive the calculation formula for the oblique surface dose. The dose variation was determined using the coefficient of variation. The maximum coefficient of variation for 66 small-field OSLDs was 1.71%. The angular dependence, obtained from the dose ratio of the dosimeter in the vertical direction, had a maximum value of 1.37. We derived a new equation in which the oblique surface dose can be calculated within the error range of −7.7-5.1%.

抄録 We report a case of late-onset hyperprogressive disease after cessation of a PD-1 inhibitor. A male was diagnosed with metastatic lung adenocarcinoma with little progression for 2 months before treatment. He received pembrolizumab as a second-line treatment and was subsequently prescribed docetaxel for 3 months until a slight increase in pleural effusion. At the time of progression to docetaxel, he commenced prednisolone because of immune-system-related diarrhea. After that, his general condition rapidly worsened with severe fatigue and hypoxia. Computed tomography revealed a massive increase of pleural effusion and replacement of almost the entire liver with cancer over a period of 5 weeks.

抄録 Polydactyly is one of the most common foot congenital anomalies. It is often detected immediately after birth, but the diagnosis can sometimes be delayed if the symptoms are less evident. A 2-year-old girl with a complaint of recurrent bleeding from the right toenail was diagnosed with foot polydactyly. She underwent corrective surgery, and her family was satisfied with the outcome. Although the diagnosis of polydactyly may be difficult in cases with minor nail problems, further radiographic evaluation will be needed for the improvement of the patient’s quality of life.

抄録 We encountered a rare case of thymic cyst accompanied by mediastinitis. A 39-year-old Japanese male presented with fever and chest pain. The chest CT revealed a mass composed of a lobular cystic lesion with inflammation, suggesting the onset of mediastinitis. A definitive histological diagnosis was not obtained, and we performed a thymectomy. Pathologically, the thymic cyst was accompanied by multiple cavities, mimicking thymic cysts, caused by the inflammatory abscess. The surrounding adipose tissue showed inflammatory cell infiltrations with chronic fibrosis. These findings indicate that clinicians should be aware that thymic cysts may cause severe mediastinitis.

抄録 A 53-year-old man was diagnosed with acute myeloid leukemia, which was refractory to chemotherapies. Systemic papules appeared afterward. The skin biopsies revealed filamentous fungal infection including fusariosis. Despite antifungal therapy, the infection did not resolve, because neutropenia persisted with the leukemia. He underwent hematopoietic stem cell transplantation (HSCT) to overcome the leukemia and restore normal hematopoiesis but died from fusariosis just before engraftment. Fusarium fujikuroi species complex was detected in blood cultures with poor antifungal susceptibility. Because restoring normal hematopoiesis is important in the treatment of fusariosis, HSCT might be considered for patients with persistent pancytopenia.

抄録 We report a 47-year-old Japanese female with 10 previous treatments for multiple bilateral renal cell carcinoma (RCC) associated with von Hippel-Lindau disease. The 14-mm right lower pole renal tumor was in contact with the right ureter. Laparoscopic cryoablation was performed to protect the ureter wrapped with gauze. Computed tomography (CT) monitoring was used to confirm the precise ≥ 6 mm ice-ball margin. There was no local progression at 6-months post-surgery. The serum creatinine has been stable. This is apparently the first report of combined laparoscopic and CT monitoring of an ice-ball formation and its margin during cryoablation for RCC.

抄録 We report a case of psoriatic arthritis where oligoarthritis preceded the skin lesions. A 57-year-old man complained of left third-finger pain. Laboratory examinations were negative for anti-cyclic citrullinated peptide antibodies and rheumatoid factor; he was treated for suspected rheumatoid arthritis. Six years later, X-ray revealed enthesitis of his fingers and wrist joint. At 9.5 years after the initial visit, skin lesions appeared in the left auricular region and buttock and dermatopathology findings indicated psoriasis vulgaris. The final diagnosis was psoriatic arthritis. In cases of seronegative oligoarthritis, psoriatic arthritis must be considered because some patients demonstrate osteoarticular lesions preceding skin lesions.

抄録 Taxanes are key drugs for patients with breast cancer. A major adverse effect associated with the administration of the taxane docetaxel is chemotherapy-induced peripheral neuropathy (CIPN). We are conducting a singlecenter, single-arm, open-label historical control trial to evaluate the ability of compression therapy using stockings or sleeves to prevent CIPN due to docetaxel treatment. The primary endpoint is the incidence of all-grade CIPN according to patients’ records until 3 weeks after the fourth docetaxel administration. This study’s results will clarify whether compression therapy using stockings or sleeves can prevent CIPN in breast cancer patients.

抄録 Gastric cancer usually arises in middle-aged to older patients, and is rarely found in younger patients. The clin-ical characteristics, etiology, prognosis, preventive methods and treatment of gastric cancer in young patients have not been fully investigated because of its low prevalence. In this review, we discuss the current under-standing and clinical problems associated with gastric cancer in young patients. Helicobacter pylori (H. pylori), which is a major cause of gastric cancer, especially in older populations, is closely associated with gastric cancer in young patients as well as in older patients. Gastric cancer in young patients tends to be diagnosed at an advanced stage with alarm symptoms. However, young patients with advanced gastric cancer tend to have a favorable general condition and organ function, so they can tolerate intensive systematic chemotherapy. Unfortunately, the prognosis of gastric cancer in young patients with an advanced stage is not favorable. We should not take this rare disease lightly, given its poor prognosis if patients are diagnosed at an unresectable stage. The evaluation of the H. pylori infection status and performance of H. pylori eradication therapy to prevent gastric cancer in young patients as well as the development of more intensive chemotherapy regimens for unre-sectable gastric cancer in young patients are warranted.

抄録 Alkaline phosphatase (ALP) is an enzyme that is expressed in a variety of tissues. Among the isoforms of ALP, bone-specific alkaline phosphatase (BAP) is used as a marker for evaluating bone metabolism. We investigated the clinical usefulness of the ratio of serum BAP to total ALP for the diagnosis of various disorders in general practice. We retrospectively analyzed the cases of 107 Japanese patients whose serum BAP levels were exam-ined, focusing on clinical characteristics. We observed that the BAP/ALP ratios of the patients with fever and those with inflammatory diseases were significantly lower than the ratios of other patient groups. The BAP/ALP ratios of the patients with osteoporosis and those with metabolic bone diseases were higher than those of the patients with other conditions. The BAP/ALP ratio was found to be negatively correlated with age, a cor-relation that has not been found in other ethnicities. The serum BAP/ALP ratio was inversely correlated with serum CRP levels but was positively correlated with serum albumin levels and hemoglobin concentrations. Collectively, our results suggest that the BAP/ALP ratio could be a useful predictor for important geriatric con-ditions seen in general practice.
