Bisphosphonates are potent inhibitors of bone resorption and considered as a gold standard and are generally recommended as first-line therapy in patients with osteoporosis. Though bisphosphonates are shown to significantly reduce the risk of vertebral, non-vertebral and hip fractures, recent reports suggest a possible correlation between long-term bisphosphonate therapy and the occurrence of insufficiency fractures owing to prolonged bone turnover suppression. We report a patient with non-traumatic stress fractures of bilateral femoral shafts related to long-term bisphosphonate therapy indicating the need for a critical evaluation of patients with long-term bisphosphonate therapy.

Baker cyst is an enlargement of the gastrocnemius-semimembranosus bursa. Neuropathy can occur due to either direct compression from the cyst itself or indirectly after cyst rupture. We report a unique case of a 49-year-old man with left sole pain and paresthesia who was diagnosed with posterior tibial neuropathy at the lower calf area, which was found to be caused by a ruptured Baker cyst. The patient's symptoms resembled those of lumbosacral radiculopathy and tarsal tunnel syndrome. Posterior tibial neuropathy from direct pressure of ruptured Baker cyst at the calf level has not been previously reported. Ruptured Baker cyst with resultant compression of the posterior tibial nerve at the lower leg should be included in the differential diagnosis of patients who complain of calf and sole pain. Electrodiagnostic examination and imaging studies such as ultrasonography or magnetic resonance imaging should be considered in the differential diagnosis of isolated paresthesia of the lower leg.

Squamous cell carcinoma of the ovary is rare. It is considered to be associated with benign cystic teratoma, Brenner tumor and ovarian endometriosis which undergo malignant degeneration in their epithelial layers. Although ovarian metastasis from advanced cervical cancer is well known, however, ovarian metastasis from microinvasive cervical cancer is extremely rare. Because there are few reports about squmaous cell carcinom of the ovary, the pathogenesis is still not well known. Recently we experienced a case of squamous cell carcinoma in ovary presenting 109 months after surgical therapy of a microinvasive cervical cancer. We report this case with a brief review of literature and possible pathogenesis.

In Korea, the Hospice, Palliative Care, and Life-sustaining Treatment Decision-making Act was enacted in February 2016 in order to ensure that the patient's self-determination in end-of-life care processes is respected. To enhance physicians' understanding of this act and to provide proper criteria for medical judgment in variety of clinical settings, consensus guidelines were published in November 2016. In this article, the characteristics of these guidelines and related issues regarding the definitions of ‘the end stage of disease’ and ‘last days of life’ and the criteria for medical judgment are presented and summarized. According to the guidelines, the term ‘end stage of disease’ refers to a state in which there is no possibility of a fundamental recovery and the symptoms are expected to worsen within months. The terms ‘the last days of life’ and ‘the final days of life’ refer to a state in which, despite treatment, the patient's condition is worsening and death is impending, with no possibility of recovery. The attending physician and another relevant specialist should both judge a patient's medical condition as either ‘end stage of disease’ for hospice/palliative care or ‘the last days of life’ for dying patient care according to the law. Caregivers should provide appropriate medical information to eligible patients for palliative or ‘end stage of disease’ care through advance care planning. Therefore, it is critically necessary that caregivers understand the legitimate process of hospice/palliative and dying patient care based on the patient's wishes and best interests. Physicians should apply these consensus guidelines to eligible patients considering their clinical course and the patients' wishes.

BACKGROUND: Sleep is an essential restorative physiologic phenomenon. Impaired sleep results in significant negative effect to the health. Symptoms like sleep initiation difficulty, frequent awakening, severe snoring have related to poor sleep quality. We studied frequency and compared the characteristics of common sleep disorders at family practice. METHODS: We surveyed patients over 18 years of age and their guardians who visited 16 familial practices for 6 days. We investigated sleep characteristics, frequency of sleep disorder and associated factors by questionnaires and analyzed by frequency analysis, Spearman's correlation coefficient, multiple logistic regression. RESULTS: We enrolled 1,117 participants. Older participants were more likely to report early sleep onset and off time, short sleep duration. Mean number of awakening during a typical night is 1.69. Female complained difficulties in initiation and maintenance of sleep more than male. A total of 32.5% had these insomnia symptoms and related to hypertension, stroke, stress, arthralgia, depression, urological disorder. 31.1% had excessive daytime sleepiness, related to stress, arthralgia, depression. Loud snoring and gasp for breath showed positive correlation between male, high BMI. Disrupted sleep over 3 times was related to old age, female, diabetes, hypertension, stroke, stress, arthralgia, depression. Restless leg syndrome were high in elderly, high BMI, stress, arthralgia and depression. CONCLUSION: About one in three who visit in primary medical practice have sleep disorder symptoms like insomnia, daytime fatigue, snoring. 3% of them have gasp for breath, 8% have restless leg syndrome.

Purpose:
Considering the high disease burden and unique features of Asian patients with breast cancer (BC), it is essential to have a comprehensive view of genetic characteristics in this population. An institutional targeted sequencing platform was developed through the Korea Research-Driven Hospitals project and was incorporated into clinical practice. This study explores the use of targeted next-generation sequencing (NGS) and its outcomes in patients with advanced/metastatic BC in the real world.
Materials and Methods:
We reviewed the results of NGS tests administered to BC patients using a customized sequencing platform—FiRST Cancer Panel (FCP)—over 7 years. We systematically described clinical translation of FCP for precise diagnostics, personalized therapeutic strategies, and unraveling disease pathogenesis.
Results:
NGS tests were conducted on 548 samples from 522 patients with BC. Ninety-seven point six percentage of tested samples harbored at least one pathogenic alteration. The common alterations included mutations in TP53 (56.2%), PIK3CA (31.2%), GATA3 (13.8%), BRCA2 (10.2%), and amplifications of CCND1 (10.8%), FGF19 (10.0%), and ERBB2 (9.5%). NGS analysis of ERBB2 amplification correlated well with human epidermal growth factor receptor 2 immunohistochemistry and in situ hybridization. RNA panel analyses found potentially actionable and prognostic fusion genes. FCP effectively screened for potentially germline pathogenic/likely pathogenic mutation. Ten point three percent of BC patients received matched therapy guided by NGS, resulting in a significant overall survival advantage (p=0.022), especially for metastatic BCs.
Conclusion
Clinical NGS provided multifaceted benefits, deepening our understanding of the disease, improving diagnostic precision, and paving the way for targeted therapies. The concrete advantages of FCP highlight the importance of multi-gene testing for BC, especially for metastatic conditions.
