Abstract
Malignant mesothelioma (MM) is uncommon in cats and dogs and can be challenging to diagnose. Adequate tissue sampling is required for superior diagnostic accuracy. Protoporphyrin IX, a metabolite of 5-aminolaevulinic acid (5-ALA), is a photosensitiser for photodynamic diagnosis (PDD). To the best of our knowledge, no study has reported the use of 5-ALA-PDD to detect MM in veterinary medicine. The present study describes the use of 5-ALA-PDD for MM diagnosis in a cat and dog, as well as the effectiveness of intracavitary chemotherapy. We evaluated the use of PDD with 5-ALA hydrochloride (5-ALA-PDD) in two cases of MM. A 12-year-old cat presented with a 1-month history of respiratory distress, and a 9-year-old dog presented with a 3-month history of mild abdominal distention. We endoscopically biopsied lesions in both the cases using 5-ALA-PDD. Histopathological examination revealed mesothelioma, and immunohistochemical staining was positive for calretinin. Both patients were treated with carboplatin. The cat died of respiratory failure. Although, the dog's condition improved 21 days after the first chemotherapeutic drug administration, the dog died on day 684 owing to cardiac-related issues. 5-ALA-PDD is thus, safe and feasible for the diagnosis of MM in veterinary medicine.

Abstract
AIM We developed the Training Program on Child Abuse Prevention for Citizens (TCAP-C) and tested its effects and acceptability among citizen leaders (CLs). METHODS Community-based participatory research using a pretest-posttest follow-up design was conducted in Tokyo, Japan from September 2021 to March 2022. Participants completed questionnaires before, upon completion, and one month and three months after TCAP-C. Recognition, knowledge, and behaviors regarding child abuse and community consciousness were collected and compared before and one and three months after TCAP-C, and the degree of satisfaction, understanding, and meaningfulness were collected upon completion. We analyzed data using repeated-measures ANCOVA. RESULTS A total of 111, 98, 101, and 94 participants completed the questionnaires before, upon completion, and one and three months after TCAP-C, respectively. Overall, the recognition, knowledge, and community consciousness scores significantly improved from before to one month and three months after TCAP-C. Regarding the behaviors, only the behaviors of learning and watching over were significantly improved from before to one month after TCAP-C; however, those behaviors were not different between before and three months after TCAP-C. Furthermore, 95% participants reported being entirely satisfied with TCAP-C, and 85% and 91% reported good understanding and meaningfulness of the program. CONCLUSIONS TCAP-C is acceptable and can improve CL recognition, knowledge, and community consciousness.

Abstract
The aim of this study was to obtain basic data that might serve as criteria in the diagnosis of delayed eruption of the permanent teeth. The synchronicity of the eruption of corresponding contralateral teeth was determined. Data were obtained on both the deciduous and permanent dentition based on records made every 2 months at the Department of Pediatric Dentistry of Tokyo Dental College. These data were then used to investigate bilateral differences in the timing of eruption of the permanent teeth. Over 80% of incisors, first molars, mandibular canines, and maxillary first premolars erupted within 4 months of their contralateral counterparts, while this occurred in 75% of maxillary canines, mandibular first premolars, and mandibular second molars, 70% of maxillary and mandibular second premolars, and 65% of maxillary second molars. Bilateral differences in the timing of permanent tooth eruption varied depending on type of tooth, and these differences tended to be smaller for teeth erupting at an earlier point in the order of eruption, and greater for those erupting at a later point. These results suggest that the failure of a contralateral tooth to erupt within 4 months of its counterpart might serve as a criterion in a diagnosis of suspected delayed eruption of a permanent tooth.

Abstract
We report the successful morphological correction of a maxillary lateral incisor with a talon cusp and the preservation of vital pulp by employing an intentional partial pulpotomy. A talon cusp is a comparatively rare morphological tooth anomaly that may cause multiple clinical problems. An 11-year-old girl was referred to our department for morphological correction of a maxillary lateral incisor with a talon cusp prior to orthodontic treatment. Following a detailed CT examination of the interior morphology, the abnormal cusp was resected and an intentional partial pulpotomy performed. Five years postoperatively, the tooth showed no abnormalities. These results indicate that an intentional partial pulpotomy following a detailed CT examination is effective in correcting complicated morphological anomalies such as a talon cusp containing extended dental pulp.

Abstract
Dental treatment for patients with physical or mental disability is often performed under general anesthesia due to level of cooperation with treatment, type and location of treatment, time required, or number of times patient is required to attend hospital. University hospitals are receiving an increasing number of requests from local private dentists and dental clinics to provide dental care for patients with physical or mental disability which can only be performed under general anesthesia. We carried out a retrospective survey of the routes of referral and types of dental treatment carried out in such patients under general anesthesia at Tokyo Dental College Suidobashi Hospital. The survey covered a 5-year, 9-month period from April 2006 to December 2011, during which 163 patients, comprising 106 men and 57 women, were treated. Their age ranged widely, from 2 to 53 years, with a high proportion (118 patients, 72.4%) being minors aged under 20. Among the total number of patients, 69 (42.3%) had disorders associated with mental retardation. One hundred and two patients (62.6%) had been referred from other medical institutions, with a particularly high number coming from public dental clinics for patients specializing in such patients. Conservative restorative procedures were performed in most cases (59.4%), with composite resin restorations being particularly frequent. After treatment, many patients returned to their referring medical institutions, which were responsible for subsequent management, but information on the posttreatment status was not available for some patients. Tokyo Dental College Suidobashi Hospital frequently collaborates with local medical institutions, and the present results suggest the importance of improving such collaboration.

Abstract
PURPOSE The fusion of primary teeth may be associated with the absence of 1 of the 2 permanent successors. Moreover, even if both successors erupt, developmental disturbances such as microdontia or delayed tooth formation may occur. The purpose of this study was to elucidate the effects of different combinations of fused primary teeth on the eruption of permanent successors. METHODS One hundred ninety-seven children with 247 fused primary teeth were examined. Combinations of primary teeth involved in the fusion were identified, and the effects of these different combinations on the presence, morphology, and eruption of the permanent successors were determined. RESULTS Three types of fusion in the primary teeth were identified: (1) between the maxillary central and lateral incisors (UCI/LI); (2) between the mandibular central and lateral incisors (LCI/LI); and (3) between the mandibular lateral incisor and canine (LLI/C). The results revealed an absence of the successional lateral incisor in 65% of UCI/LI cases and 74% of LLI/C cases, whereas only 16% of LCI/LI cases resulted in a missing successor. CONCLUSIONS Fused primary teeth are highly correlated with the absence of permanent teeth, and the prevalence depends on the combination of fused primary teeth.

Abstract
We demonstrate 1 GHz count rate photon detection with photon number resolution by using a multi-pixel photon counter (MPPC) and performing baseline correction. A bare MPPC chip mounted on a high-frequency circuit board is employed to increase response speed. The photon number resolving capability is investigated at high repetition rates. This capability remains at a repetition rate of 1 GHz and at rates as high as an average of 2.6 photons detected per optical pulse. The photon detection efficiencies are 16% at λ = 450 nm and 4.5% at λ = 775 nm with a dark count rate of 270 kcps and an afterpulse probability of 0.007.

Abstract
A supernumerary tooth fused to a normal tooth often causes malocclusion and esthetic problems because of malformation and large crown. This requires treatment such as sectioning and extraction of the supernumerary tooth, modification of crown shape by contouring and restoration, or extraction. Moreover, endodontic treatment is often required as part of the procedure since pulp exposure occurs frequently during sectioning and modification of crown shape. The purpose of this paper was to report the case of a supernumerary tooth fused to the permanent maxillary left central incisor in a 9-year-old boy with unilateral (left side) cleft lip and palate and describe its management. After a thorough examination employing X-ray Computed Tomography (CT), the supernumerary tooth was separated from the central incisor at the fusion site and extracted under local anesthesia. No endodontic treatment was performed on the conserved central incisor. The central incisor's rotation was corrected by orthodontic treatment, followed by modification of the crown shape with composite resin. More than 4 years have passed since the first operative treatment, and the central incisor still remains vital. This case shows that a precise diagnosis is important in sectioning a fused tooth, and that CT-based data are very useful in planning treatment.

Abstract
Multipixel silicon avalanche photodiodes (Si APDs) are novel photodetectors used as silicon photomultipliers (SiPMs), or multipixel photon counter (MPPC), because they have fast response, photon-number resolution, and a high count rate; one drawback, however, is the high dark count rate. We developed a system for cooling an MPPC to liquid nitrogen temperature and thus reduce the dark count rate. Our system achieved dark count rates of <0.2 cps. Here we present the afterpulse probability, counting capability, timing jitter, and photon-number resolution of our system at 78.5 K and 295 K.

Abstract
e16558 Background: Recently, the number of young patients with invasive uterine cervical carcinoma is increasing in Japan because of earlier sexual activity and low rate of receiving screening test of uterine cervical carcinoma in Japan. However, no large studies have been performed so far to evaluate the clinical outcomes of curative intended radiation therapy for young patients with invasive uterine cervical carcinoma in Japan. Then, the current study was designed. Methods: One hundred and five patients under 40 years old were registered in the mulitiinstitutional study. The median age was 34.5 years old (range: 24–39 years old). According to FIGO, clinical stage was as follows. Stage Ib/IIa/IIb/IIIa/IIIb/IVa were 10/4/38/2/47/3, respectively. The median maximal tumor diameter was 5.5 cm (range: 2–9.2 cm). Curative intended radiation therapy was the combination of high-dose rate intracavitary brachytherapy (HDR-ICBT) combined with external beam radiation therapy (ERT). The total dose of ERT ranged from 44 Gy to 68 Gy. The total dose of HDR-ICBT to point A ranged from 12 Gy to 48 Gy. Eighty five patients received chemotherapy. Results: The 5-year overall survival rate and local control rate of all patients was 58.4 % and 59.3 %, respectively. The 5-year overall survival rates of stage Ib/IIa/IIb/IIIa/IIIb/IVa were 90.0 %/not available (NA)/73.8%/100%/37.4%/0%, respectively. The 5-year local control rates of Stage Ib/IIa/IIb/IIIa/IIIb/IVa were 80.0 %/50.0 %/73.8 %/100 %/54.6 %/NA, respectively. Sixteen patients experienced grade 3 or greater late radiation morbidity. Conclusions: Clinical outcomes of stage I-II in the young were equivalent to the Japanese standard treatment results of all ages. However, clinical outcomes of stage IIIb and IVa in the young were worse than those of all ages (5-year OS of all ages in Japan: IIIb: 50 %, IVa: 25 %). No significant financial relationships to disclose.

Abstract
PURPOSE To establish dosimetric predictors of radiation esophagitis (RE) in patients treated with a combination of carboplatin, paclitaxel, and radiotherapy. METHODS AND MATERIALS Three-dimensional radiotherapy plans of 26 patients with non-small-cell lung cancer who received 50-60 Gy of radiotherapy concurrently with weekly administration of carboplatin (AUC 2) and paclitaxel (40-45 mg/m(2)) were reviewed in conjunction with RE. The factors analyzed included the following: percentages of organ volumes receiving >40 Gy (V40), >45 Gy (V45), >50 Gy (V50), and >55 Gy (V55); the length of esophagus (total circumference) treated with >40 Gy (LETT40), >45 Gy (LETT45), >50 Gy (LETT50), and >55 Gy (LETT55); the maximum dose in the esophagus (Dmax); and the mean dose in the esophagus (Dmean). Data were obtained on the basis of superposition algorithm. RESULTS All factors except Dmax showed statistical correlation with RE. Good correlations were shown between RE and LETT45 (rho = 0.714) and V45 (rho = 0.686). CONCLUSIONS LETT45 and V45 appear to be useful dosimetric predictors of RE. It is also suggested that Dmax does not predict RE.

Abstract
We studied the serological cross-reactions among Bartonella henselae, Chlamydia pneumoniae and Coxiella burnetii by indirect fluorescence antibody (IFA) method, using sera from 8 patients with cat scratch disease (CSD), 13 patients with C. pneumoniae infection and 12 patients with acute Q fever. B. henselae IgG antibody was negative in 13 patients with C. pneumoniae infection, and was positive in 3 (titers being 1:64) of 12 patients with Q fever, whereas B. henselae IgM antibody was negative in all the patients with C. pneumoniae infection or Q fever. C. burnetii IgG antibody was removed by absorption of these 3 sera with C. burnetii antigens, whereas B. henselae IgG antibody did not change. C. pneumoniae IgG antibody was positive in 3 (titers being 1:125 in two, 1:32 in one) of 8 patients with CSD. Both C. pneumoniae and B. henselae IgG antibody titers were significantly reduced by absorption of these 3 sera with B. henselae antigens. C. burnetii IgG or IgM antibodies were negative in all patients with CSD. In conclusion, no serological cross-reaction between B. henselae and C. burnetii was observed. On the other hand. B. henselae IgG antibody cross-reacted to C. pneumoniae antigens, whereas C. pneumoniae IgG antibody did not cross-react to B. henselae antigens. Our findings suggest that determination of B. henselae IgG or IgM antibodies were not influenced by C. pneumoniae and C. burnetii antigens.

Abstract
BACKGROUND AND PURPOSE The incidence and extent of radiation esophagitis were assessed endoscopically in patients treated with concurrent chemoradiotherapy. PATIENTS AND METHODS Eighty-two patients who received thoracic radiotherapy for lung, thymic, or esophageal cancer were investigated endoscopically from July 1991 to the end of 1997. Among them, 23 esophageal cancer patients were treated with radiation alone, and the others were treated with concurrent chemoradiotherapy. Esophageal endoscopy was performed during or just after radiotherapy. The presence of radiation esophagitis was assessed and assigned an endoscopic score (i.e. grade 0 for normal, 1 for erythema, 2 for erosion or sloughing, 3 for ulcer, hemorrhage, or stricture). The symptomatic grade was assessed using the RTOG (Radiation Therapy Oncology Group) acute radiation morbidity score. RESULTS A correlation was seen between endoscopic and RTOG scores. However, even some patients with RTOG grade 0 to 1 had endoscopic grade 3 esophagitis. Endoscopic grade 3 was observed in 16 (27.1%) patients in the concurrent chemoradiotherapy group, whereas it did not occur in any patient in the radiation alone group (P=0.004). CONCLUSIONS Our results suggest that (1) RTOG score correlates closely to esophageal mucosal damage, and (2) more severe esophagitis occurs in those undergoing concurrent chemoradiotherapy than those undergoing radiotherapy alone [corrected].

Abstract
PURPOSE To evaluate the outcomes of orbital irradiation with or without high-dose or pulsed corticosteroids in patients with Graves' ophthalmopathy (GO). METHODS AND MATERIALS One hundred and twenty-one patients with moderate to severe GO who received orbital irradiation from 1987 to 1997 were retrospectively analyzed. A total dose of 20 Gy in 10 fractions was delivered to the bilateral retrobulbar volume. Eighty-six patients were treated in combination with high-dose or pulsed corticosteroids and irradiation. Univariate and multivariate analyses were performed to assess the prognostic variables. RESULTS The median follow-up period was 26 months. The overall clinical response was evaluated as excellent in 17 patients (14%), good in 65 (54%), fair in 31 (25%), no response in 7 (6%), and worse in 1 (1%). The best responses were noted for soft-tissue signs, extraocular muscle involvement, and sight loss, while a limited response was noted for proptosis. Multivariate analysis revealed that the use of high-dose corticosteroid or pulsed corticosteroids, female gender, and a shorter duration of ophthalmopathy before radiotherapy were significantly correlated with favorable outcomes. No long-term complications related to radiotherapy were observed. CONCLUSION Orbital irradiation combined with high-dose or pulsed corticosteroids is an effective treatment for moderate to severe GO, especially in cases with major manifestations of soft-tissue signs, extraocular muscle impairment, or sight loss.

Abstract
Surgical management of unerupted teeth depends upon a thorough understanding of anatomic, physiologic and pathologic factors. Attention has been given to problems of eruption in the maxillary anterior region. It is a region where a variety of anomalies occur. Since the maxillary anterior region influences appearance so greatly, early detection of difficulties and careful planning and treatment can be extremely beneficial to patients. The purpose of this case report is to present a case of maxillary permanent canine impaction in a horizontal displacement that developed after loss of the deciduous canine to chronic apical periodontitis, and incomplete root resorption of the deciduous canine.
