Folliculotropic mycosis fungoides treated with electron beam therapy that evolved into fatal, tumor-stage mycosis fungoides and erythroderma with multiple ulcerations

　A 71-year-old woman diagnosed with mycosis fungoides with multiple erythematous plaques and follicular papules on the scalp, trunk, and thigh was referred to our institution. Folliculotropic mycosis fungoides was histologically diagnosed, and the erythematous papules and plaques regressed temporarily after total-skin electron beam therapy. The patient then developed tumors and erythroderma. The area of painful erosion spread, and her condition rapidly worsened. The patient died 3 years and 4 months after the first examination due to multiple organ failure caused by sepsis. The cause of rapid evolution into erythroderma remains elusive and requires further investigation in similar cases

Immune-related aseptic meningitis diagnosed by Cube FLAIR on enhanced magnetic resonance imaging for a lung cancer patient administered atezolizumab: A case report

Immune checkpoint inhibitors (ICIs) can cause immune-related adverse events (irAEs), such as neurological toxicity. A 46-year-old man was diagnosed with squamous cell lung cancer. Lung cancer recurred 3 years after he experienced left segmental lung rejection. Therefore, he received atezolizumab as fourth-line chemotherapy. He experienced fever, headache, and decreased consciousness 10 days after the first dose of atezolizumab. Plain head computed tomography and cerebrospinal fluid examination showed no significant findings. Magnetic resonance imaging (MRI) with a Gadolinium (Gd)-enhanced Cube fluid-attenuated inversion recovery (FLAIR) sequence showed nodular abnormalities with contrast enhancement. Thus, aseptic meningitis caused by ICIs was suspected. His consciousness level gradually improved with glucocorticoid therapy. Moreover, most nodular abnormalities observed on cerebral MRI disappeared concurrently. Thus, Gd-enhanced Cube FLAIR sequence has the unique ability to reveal immune-related aseptic meningiti

Detection of Glaucoma and Other Vision-Threatening Ocular Diseases in the Population Recruited at Specific Health Checkups in Japan

[Background:] The efficacy of vision screening for adults has not been well established. The present study aimed to investigate the prevalence of vision-threatening ocular diseases, including glaucoma, among subjects who participated in specific health checkups in Japan. [Methods:] This cross-sectional study included 1360 individuals who underwent comprehensive ophthalmic examinations at 16 ophthalmology clinics located in three municipalities. We surveyed the study participants using a questionnaire. The participants also underwent visual acuity and refraction tests, intraocular pressure tests, slit-lamp microscopy, fundus examinations, fundus photography, optical coherence tomography, and static perimetry. [Results:] The mean age of the subjects was 63.7 ± 8.7 years (range, 40– 74 years). Among the 1360 participants, 168 (12.4%) were diagnosed with glaucoma and 33 (2.4%) with preperimetric glaucoma. Cataracts were seen in 741 participants (54.5%), and 77 (5.7%) were diagnosed with clinically significant cataracts. Retinal diseases included macular degeneration (1.2%), diabetic retinopathy (1.0%), chorioretinal atrophy (0.5%), macular epiretinal membrane (2.9%), branch retinal vein occlusion (0.7%), and others (2.0%). Regarding the type of glaucoma, 93.5% of participants with glaucoma were diagnosed with open-angle glaucoma in a broad sense (81.0% with normal-tension glaucoma and 12.5% with primary open-angle glaucoma). Multivariate analysis showed that male sex, age, systemic comorbidities, and myopia were significant risk factors for open-angle glaucoma. [Conclusion:] Many adults with ocular diseases were screened by ophthalmic checkups. The addition of simultaneous ophthalmic checkups to specific health checkups could be an effective measure for the prevention of visual impairment in the older population

Effects after starting or switching from bisphosphonate to romosozumab or denosumab in Japanese postmenopausal patients

Purpose We aimed to investigate the longitudinal changes in bone metabolic markers and bone mineral density (BMD) after starting or switching from bisphosphonate (BP) to romosozumab (ROMO) or denosumab (DENO) therapies over 12 months and to determine predictors that establish associations with changes in BMD among the patients received the ROMO therapy. Methods Postmenopausal osteoporosis patients with a high risk of fracture-154 in total-were recruited; their therapies were switched to ROMO or DENO from BP/naive or vitamin D (ND) (ND-ROMO: 43, BP-ROMO: 38, ND-DENO: 38, and BP-DENO: 35). Longitudinal changes in bone metabolic markers and BMD were evaluated. Results ROMO groups showed significant increases in BMD of the lumbar spine at 6 and 12 months and femoral neck at 12 months compared to the DENO groups. Although BP-ROMO showed significant increase in the lumbar spine BMD compared to BP-DENO, there were no significant differences in femoral neck and total hip BMDs between BP-ROMO and BP-DENO. Among the ROMO groups, % changes of BMD from baseline to 12 months were associated with bone metabolic markers at baseline and changes in TRACP-5b from baseline to 3 months. Conclusions ROMO continuously increased BMD for 12 months and performed better than DENO. On the other hand, effects of ROMO switched from BP on BMD of femoral neck and total hip were almost same with DENO. Bone metabolic markers at baseline and changes in TRACP-5b from baseline to 3 months may predict the efficacy of ROMO after 12 months of administration

Real-world effectiveness of screening programs for age-related macular degeneration: amended Japanese specific health checkups and augmented screening programs with OCT or AI

[Purpose] To investigate the effectiveness of screening and subsequent intervention for age-related macular degeneration (AMD) in Japan. [Study design] Best-case-scenario analysis using a Markov model. [Methods] The clinical effectiveness and cost-effectiveness of screening for AMD were assessed by calculating the reduction proportion of blindness and the incremental cost-effectiveness ratio (ICER). The Markov model simulation began at screening at the age of 40 years and ended at screening at the age of 90 years. The first-eye and second-eye combined model assumed annual state-transition probabilities in the development and treatment of AMD. Data on prevalence, morbidity, transition probability, utility value, and treatment costs were obtained from previously published reports. Sensitivity analysis was performed to assess the influence of the parameters. [Results] In the base-case analysis, screening for AMD every 5 years, beginning at age 40 years and ending at age 74 years (reflecting the screening ages of the current Japanese legal “Specific Health Checkups”) showed a decrease of 40.7% in the total number of blind patients. The screening program reduced the number of blind people more than did the additional AREDS/AREDS2 formula supplement intake. However, the ICER of screening versus no screening was ¥9, 846, 411/QALY, which was beyond what people were willing to pay (WTP) in Japan. Sensitivity analysis revealed that neither OCT nor AI improved the ICER, but the scenario in which the prevalence of smoking decreased by 30% improved the ICER (¥4, 655, 601/QALY) to the level under the WTP. [Conclusions] Ophthalmologic screening for AMD is highly effective in reducing blindness but is not cost-effective, as demonstrated by a Markov model based on real-world evidence from Japan

Boron neutron capture therapy for vulvar melanoma and genital extramammary Paget’s disease with curative responses

Abstract Background Although the most commonly recommended treatment for melanoma and extramammary Paget’s disease (EMPD) of the genital region is wide surgical excision of the lesion, the procedure is highly invasive and can lead to functional and sexual problems. Alternative treatments have been used for local control when wide local excision was not feasible. Here, we describe four patients with genital malignancies who were treated with boron neutron capture therapy (BNCT). Methods The four patients included one patient with vulvar melanoma (VM) and three with genital EMPD. They underwent BNCT at the Kyoto University Research Reactor between 2005 and 2014 using para-boronophenylalanine as the boron delivery agent. They were irradiated with an epithermal neutron beam between the curative tumor dose and the tolerable skin/mucosal doses. Results All patients showed similar tumor and normal tissue responses following BNCT and achieved complete responses within 6 months. The most severe normal tissue response was moderate skin erosion during the first 2 months, which diminished gradually thereafter. Dysuria or contact pain persisted for 2 months and resolved completely by 4 months. Conclusions Treating VM and EMPD with BNCT resulted in complete local tumor control. Based on our clinical experience, we conclude that BNCT is a promising treatment for primary VM and EMPD of the genital region. Trial registration numbers UMIN00000512

Combining Optical Coherence Tomography and Fundus Photography to Improve Glaucoma Screening

We aimed to evaluate the accuracy of glaucoma screening using fundus photography combined with optical coherence tomography and determine the agreement between ophthalmologists and ophthalmology residents. We used a comprehensive ophthalmologic examination dataset obtained from 503 cases (1006 eyes). Of the 1006 eyes, 132 had a confirmed glaucoma diagnosis. Overall, 24 doctors, comprising two groups (ophthalmologists and ophthalmology residents, 12 individuals/group), analyzed the data presented in three screening strategies as follows: (1) fundus photography alone, (2) fundus photography + optical coherence tomography, and (3) fundus photography + optical coherence tomography + comprehensive examination. We investigated the diagnostic accuracy (sensitivity and specificity). The respective sensitivity and specificity values for the diagnostic accuracy obtained by 24 doctors, 12 ophthalmologists, and 12 ophthalmology residents were as follows: (1) fundus photography: sensitivity, 55.4%, 55.4%, and 55.4%; specificity, 91.8%, 94.0%, and 89.6%; (2) fundus photography + OCT: sensitivity, 80.0%, 82.3%, and 77.8%; specificity, 91.7%, 92.9%, and 90.6%; and (3) fundus photography + OCT + comprehensive examination: sensitivity 78.4%, 79.8%, and 77.1%; specificity, 92.7%, 94.0%, and 91.3%. The diagnostic accuracy of glaucoma screening significantly increased with optical coherence tomography. Following its addition, ophthalmologists could more effectively improve the diagnostic accuracy than ophthalmology residents. Screening accuracy is improved when optical coherence tomography is added to fundus photography
