Objective: In the differential diagnosis between uterine fibroids and uterine sarcomas, realworld magnetic resonance imaging (MRI) diagnostic information is scarce; furthermore, high diagnostic sensitivity is important in clinical practice. We previously developed a diagnostic algorithm to detect uterine sarcoma with high sensitivity using simple MRI images and serum lactate dehydrogenase (LDH) levels. In this multicenter study, we investigated the preoperative diagnosis of sarcoma in the real world and further validated the usefulness of our diagnostic algorithm. Methods: Of 154 uterine sarcomas and 154 uterine fibroids treated at 15 centers between January 2006 and December 2020, 139 sarcomas (16 smooth muscle tumors of uncertain malignant potential) and 141 fibroids with diffusion-weighted imaging information were included in the analysis. The diagnostic algorithm was validated by 3 radiologists who were blinded to the clinical information and pathologic diagnoses and who read the MRIs. Results: The sensitivity/specificity of preoperative diagnosis was 77.7%/92.9% for the preoperative report; 92.1%/72.3% for algorithm A; and 82.0%/85.8% for algorithm B (McNemar’s test p<0.05). Comparison of overall survival rates among 3 groups (Group 1: negative A, Group 2: positive A and negative B; Group 3: positive B) using algorithms A and B showed p=0.012. On multivariate analysis, stage, and serum LDH level were independent prognostic factors. Conclusion MRI is useful for preoperative diagnosis of uterine sarcoma, and the sarcoma diagnostic algorithm presented in this study is an option for diagnosing sarcoma with greater sensitivity. This information should be shared with patients.

The purpose of this study was to describe the incidence, severity, and burden of injuries in Japanese male collegiate rugby union players. Initially, 170 male collegiate rugby union players from one university club were registered in this epidemiological surveillance study. The occurrence of injuries was recorded by a team medical staff during the 2017–2021 playing seasons. The incidence of injuries was 6.87 injuries/1000 h. This incidence was significantly higher during matches (100.37 injuries/1000 h) than that during training (3.63 injuries/1000 h). The severity of injuries was 31.0 days, and there were no significant differences between matches and training, or forwards and backs. The burden of injuries was 213.1 days/1000 h. This burden was significantly higher during matches (2887.8 days/1000 h) compared to training (120.1 days/1000 h). Matches had higher incidence of ankle sprain/ligament injuries (15.80 injuries/1000 h) and concussion (15.36 injuries/1000 h). The most common injury site was the ankle (1.24 injuries/1000 h). However, the greatest severity and burden were observed for knee injuries (severity: 59.1 days, burden: 48.6 days/1000 h). Furthermore, the greatest burden of injury type was knee sprain/ligament injuries (39.4 days/1000 h). In addition, the incidence of acromioclavicular joint injury was significantly higher in forwards, whereas hamstring strain was significantly higher in backs. The common injury mechanisms identified were being tackled (16.0%) and tackling (14.7%), followed by overuse (12.1%). In order to improve the player welfare of the Japanese collegiate rugby union players, it is necessary to work on the prevention strategy considering the injury profile.

Objective: Glaucoma is the most frequent cause of blindness in Japan and is primarily treated using IOP-lowering ophthalmic solutions. Although the patients themselves frequently instill ophthalmic solutions, instillation by caregivers may be necessary for various reasons. Therefore, we evaluated pharmaceutical characteristics of antiglaucoma ophthalmic solutions and their usability from the caregivers' viewpoint.Methods: Five dorzolamide hydrochloride-timolol maleate ophthalmic solutions and 2 travoprost-timolol maleate ophthalmic solutions were evaluated concerning the pharmaceutical characteristics and subjective squeezability rated by adults aged 20 years or above.Results: Among the dorzolamide hydrochloride-timolol maleate compounding ophthalmic solutions, the squeeze force was the lowest in COSOPT® ophthalmic solution (11.8 N), and DORMOLOL® combination ophthalmic solution NITTEN was rated highest, with 68.2% of the subjects placing it within the top 3 levels of a 7-level scale. Of the travoprost-timolol maleate ophthalmic solutions, the squeeze force was 9.8 N, lower than the pioneer drug, in TraTimo® combination ophthalmic solution NITTO, which was also rated in the top 3 levels by 90.3% of the subjects. A strong negative correlation was observed between the squeeze force and squeezability.Conclusion: In instillation by caregivers, the squeeze force was shown to be correlated with subjective squeezability as in instillation by patients themselves. This study provided information concerning the usability of ophthalmic solutions from the caregivers' viewpoint. For the future, it is necessary to select ophthalmic solutions from the caregivers' as well as the patients' viewpoints by utilizing information obtained in this study.

STUDY DESIGN: A retrospective cohort study. PURPOSE: This study aims to investigate postoperative shoulder imbalance (PSI) ≥5 years postoperatively in patients who underwent posterior spinal fusion using hooks at the upper instrumented vertebra (UIV) for Lenke type 1 adolescent idiopathic scoliosis (AIS). OVERVIEW OF LITERATURE: Studies have reported PSI due to excessive correction of the main thoracic curve. METHODS: We examined 56 patients with AIS who underwent a posterior spinal fusion with hooks at the UIV from 2004 to 2010. Of these, we enrolled 14 patients who underwent surgery, at least, 5 years ago. X-rays and Scoliosis Research Society-22 (SRS-22) questionnaire were administered. To evaluate the shoulder balance, T1 vertebral tilt angle (T1 tilt), clavicle angle, and radiographic shoulder height (RSH) were measured. PSI was considered as the absolute value of the postoperative RSH being ≥20 mm. Based on radiographs obtained immediately postoperatively, we divided patients into two groups as follows: the balanced group (absolute value of RSH <20 mm) and imbalanced group (absolute value of RSH ≥20 mm). RESULTS: The frequency of PSI was 28.6% immediately postoperatively, 0% 2 years postoperatively, and 7.1% at the last follow-up. In the balanced group, PSI did not occur even at 2 years postoperatively or at the last follow-up. In the imbalanced group, PSI was improved in all patients 2 years postoperatively and all patients, except one patient, at the last follow-up. No significant differences were noted in the frequency of distal adding-on at 2 years postoperatively or the last follow-up between the balanced group and the imbalanced group. We observed moderate negative correlations between the absolute value of T1 tilt and the SRS-22 pain and satisfaction at the last follow-up. CONCLUSIONS: Hooks at the UIV could adjust the shoulder balance to avoid long-term PSI in patients with AIS.

Objective: In this study, pharmaceutical properties were compared between the original and generic ophthalmic solutions containing betamethasone.Methods: The squeeze force, drop weight, surface tension, pH, kinematic viscosity, and total number of drops were measured. The drop volume was calculated from the drop weight and specific gravity. Information on preservatives contained in each product was collected from package inserts.Results: There was a significant difference in the squeeze force between the original and generic drugs. The pH and kinematic viscosity did not differ between the drugs. The drop volume was in the range of 30.3 to 47.2 μL, and the surface tension ranged between 33.7 and 65.2 mN/N. The total number of drops was approximately 100 in the original drug, being the lowest.Conclusion: The results of this study showed that the squeeze forces of all generic products but RINBETA PF, which was contained in a specific container, were smaller than that of the original product. The drop volumes of 2 generic products were ≥ 15-μL smaller than that of the original product, but they were within the permissible range. The maximum difference in the surface tension was approximately 33 mN/N, suggesting that drug solution relatively frequently overflows from the eyes. The total number of drops for all generic products was greater than that for the original product, suggesting that the former can be used at a higher frequency. Based on these results, pharmacists must select products in accordance with individual patients.

Since attention is sometimes required with regard to the use and handling of external medications or injection drugs in drug therapy, patients may have a feeling of “inconvenience”. We, therefore, focused on a feeling of “inconvenience when using” external medications and injection drugs, and conducted a questionnaire survey to investigate the level of awareness and current status of using assist devices that can effectively reduce such inconvenience. The survey took place at a pharmacy, and involved interviews using a questionnaire. Of the 197 respondents, valid responses were obtained from 147 individuals (74.6%). As the results, 25.9% of individuals using external medications or injection drugs responded ‘yes’ concerning the feeling of “inconvenience when using” them. In addition, 39.4% of individuals using eye drops and 10.5% of those using insulin similarly responded. However, only 10.9% knew of the availability of assist devices that are expected to reduce the inconvenience. The results revealed that a certain number of people feel the “inconvenience” of external dosage forms investigated in this study, suggesting the need for pharmacists to consider that patients may have problems using their medications, and to recommend and support the use of assist devices that can be operated by patients.

An inflammatory fibroid polyp (IFP) is a mesenchymal tumor of the gastrointestinal tract. IFPs in the small intestine are the most frequently detected with symptoms, such as abdominal pain and tarry stool due to intussusception. Accordingly, few studies have reported jejunal IFP as a cause of occult gastrointestinal bleeding (OGIB) diagnosed via both of capsule endoscopy (CE) and double-balloon enteroscopy (DBE). A 68-year-old woman presented with a progression of anemia and a positive fecal occult blood test result. Esophagogastroduodenoscopy and total colonoscopy findings were unremarkable. CE revealed a tumor with bleeding in the jejunum. DBE also revealed a jejunal polypoid tumor. Bleeding from the tumor seemed to have caused anemia. The patient underwent partial laparoscopic resection of the jejunum, including resection of the tumor. The tumor was histopathologically diagnosed as IFP. To our knowledge, this is the first reported case of laparoscopic resection of jejunal IFP with OGIB diagnosed via CE and DBE preoperatively.

To smoothly proceed with the national policies and projects concerning dementia measures, it is important that pharmacists who take care of patient in clinical practice sufficiently understand its contents. In this study, we conducted a questionnaire survey involving chain community pharmacists to investigate the level of awareness concerning these policies and projects. Subjects were 446 chain community pharmacists. The questionnaire consisted of 17 items (e.g. the level of awareness regarding the “Comprehensive Strategy to Accelerate Dementia Measures (New Orange Plan)”, “Dementia Supporters Caravan Program (Caravan Program)”, and “Dementia training certified pharmacist program (Certification program)”). The questionnaires were filled out anonymously. The levels of awareness concerning the “New Orange Plan” and “Caravan Program” were 34.7% and 48.9%, respectively. Sixty-one percent of subjects attended a “Dementia Supporter Training Lecture”, 30.4% of whom were wearing the “orange ring”. The levels of awareness and the hope of acquisition concerning the “Certification program” were 47.8% and 79.8%, respectively. To achieve the purpose of “contribution to early detection of dementia by pharmacist” of the “New Orange Plan”, it is necessary to conducting the workshop and to create an opportunity to come in contact with dementia patients. It is also important to recognize that it is necessary to enlighten the meaning of wearing an “orange ring” and to enlarge the circle of dementia supporters. In addition, it is thought that more dementia patients can be supported in the community by increasing the levels of awareness concerning the “Certification program” and giving appropriate advice and response.

To administer oral anticancer drugs safely, the simple suspension method has been introduced in many hospitals. Therefore, concerning drugs for which it is unclear whether or not this method is applicable, testing must be able to be conducted at any time. In this study, we investigated 20 oral anticancer drugs to expand information on the application of the simple suspension method. Disintegration/suspension and permeability tests were conducted, as described in the 3rd version of the Tube Administration Handbook for Oral Drugs. All products were disintegrated/suspended after 10 minutes. On permeability tests, there was no residue in any tube for tubal feeding. On the final evaluation, the products were regarded as suitable (grade 1). Bicalutamide tablets (80 mg, TCK and KN), which were analyzed in this study, were regarded as suitable (grade 1) on the final evaluation. On the other hand, the simple suspension method is not applicable for a brand-name drug, Casodex^® tablets (80 mg). This may be related to the different additives. Furthermore, the results suggest that, even when the simple suspension method is not applicable for a brand-name drug, it may become applicable for generic drugs. This may provide a new merit for promoting the use of generic drugs.
