A young child with VACTERL association who refused oral intake and had relied on gastric tube feeding for almost all of her nutritional intake since birth was initially managed with nutritional guidance based on the assumption that refusal was due to oral hypersensitivity. However, no improvement was observed in the refusal of oral intake, and her inherent developmental delay and bilateral hearing loss prevented the continuation of nutritional guidance. A speech-language-hearing therapist was then consulted to assess the patient’s swallowing function, and the diagnosis was that the lack of experience of oral intake itself and the dependence on tube feeding were more likely causes of the refusal than oral hypersensitivity. We therefore decided to use the approach proposed by Tazumi et al. for stepwise management of eating disorders requiring tube feeding in young children. This allowed us to create a step-bystep management plan toward achieving oral intake, resulting in gradual but significant changes in the patient's eating behavior. Although oral intake has not been achieved as of the time of writing, we are continuing to manage the patient with this trial-and-error approach.

Pelvic floor muscles play an important role in inner unit functioning related to excretion, reproduction, support of pelvic organs, posture, and respiration, while their weakening is a characteristic health problem for many women. The pelvic floor is closely related to women’s life events, and protection and strengthening of the pelvic floor in accordance with life stages will lead to the prevention of pelvic floor disorders (pelvic frailty). Pelvic floor muscle exercises may be the first choice for prevention, improvement, and/or conservative treatment of pelvic organ prolapse caused by weakening of pelvic floor muscle groups. Also, pelvic floor muscle exercises can be done on a daily and continuous basis as a fitness activity; but proper assessment and practice with appropriate methods are important. In addition, an integrated program that includes lifestyle modification can enhance its effectiveness. In order to realize the lifelong well-being of women, there is a need to further develop effective pelvic floor exercises in creating a more comprehensive prevention-care health system for society.

Objective:
Maternal embryonic leucine zipper kinase (MELK) is receiving an attention as a therapeutic target in various types of cancers. In this study, we aimed to evaluate the prognostic significance of MELK expression in ovarian cancer using clinical samples, and assessed the efficacy of a small molecule MELK inhibitor, OTS167, using patient-derived ovarian cancer cells as well as cell lines.
Methods:
Expression levels of MELK in 11 ovarian cancer cell lines were confirmed by western blotting. Inhibitory concentration of OTS167 was determined by colorimetric assay.MELK messenger RNA (mRNA) expression was evaluated in 228 ovarian cancer patients by quantitative polymerase chain reaction. Growth inhibition of OTS167 was also evaluated using freshly-isolated primary ovarian cancer cells including spheroid formation condition.
Results:
MELK mRNA expression was significantly higher in ovarian cancer than in normal ovaries (p<0.001), and high MELK mRNA expression was observed in patients with advanced stage, positive ascites cytology and residual tumor size. Patients with high MELK mRNA expression showed shorter progression-free survival (p=0.001). Expression of MELK was also confirmed in 10 of 11 ovarian cancer cell lines tested, and the half maximal inhibitory concentration of MELK inhibitor, OTS167, ranged from 9.3 to 60 nM. Additionally, OTS167 showed significant growth inhibitory effect against patient-derived ovarian cancer cells, regardless of their tumor locations, histologic subtypes and stages.
Conclusions
We demonstrated MELK as both a prognostic marker and a therapeutic target for ovarian cancer using clinical ovarian cancer samples. MELK inhibition by OTS167 may be an effective approach to treat ovarian cancer patients.

Objective: Lenvatinib is an oral multitarget tyrosine kinase inhibitor (mTKI) and is recommended for patients with advanced hepatocellular carcinoma (HCC) with Child-Pugh A liver function, who are not amenable to surgical resection, locoregional treatment, or transcatheter arterial chemoembolization. Hepatogastric fistula is a rare complication with a poor prognosis in patients with HCC. Previous reports on fistula formation during mTKI therapy for HCC were all associated with sorafenib. Here, we report the first case of recurrent hepatogastric fistula during lenvatinib therapy for advanced HCC managed using an over-the-scope clip (OTSC).Patient: We present the case of a 73-year-old man with alcoholic liver cirrhosis who was treated for multiple HCC for 7 years. HCC was treated using repetitive transcatheter arterial chemoembolization, radiofrequency ablation, and sorafenib. Owing to disease progression, lenvatinib treatment was started. During lenvatinib treatment, recurrent hepatogastric fistulas developed. An OTSC was useful for fistula closure and prevention of recurrence.Results: The major cause of fistula formation is considered to be the direct invasion of HCC; however, HCC treatment might also be a contributing factor in our case. In addition, OTSC was useful for fistula closure.Conclusion: Clinicians should be aware of the fatal complications during HCC treatment.

Pelvic floor trauma developing into pelvic frailty is a significant concern in urogynecology or orthopedics. The majority of women who have experienced vaginal childbirth are affected, to a certain extent, by some form of pelvic floor damage, thereby eliciting substantial alterations of functional anatomy in the pelvic cavity which are manifested as urinary incontinence or pelvic organ prolapse (e.g., uterine prolapse). With the above in mind, medical researchers, continence experts, and continence exercise practitioners in the research areas of sports medicine and rehabilitation medicine believe that the coordinated activity of pelvic floor muscles, in association with the abdominal muscles, is a prerequisite for urinary and defecatory continence. Since the pelvic floor forms the base of the abdominal cavity, stronger pelvic floor muscles are crucial in maintaining such capabilities. Opposing action of the abdominal and pelvic floor muscles ensures that exercises for one may also strengthen the other. Appropriate abdominal maneuverability or logical exercise training of the abdominal muscles may thus be beneficial in maintaining not only strength but also coordination, flexibility, and endurance of pelvic floor muscles and abdominal muscles. Such exercises, collectively known as pelvic floor muscle training, may be effective for long-term pelvic cavity care and also in rehabilitating cases of pelvic floor dysfunction. Further research is needed, however, in determining whether pelvic floor muscle function can be truly enhanced or maintained by such exercises in cases of pelvic floor dysfunction and/or decreased urinary continence.
