Palliative care in rural areas can be difficult to assess and, often is of lower quality compared to more densely populated regions. A program of multicenter palliative care discussion forum via tele-videoconference may be a promising tool for exchanging valuable experience and constructing a comprehensive hospice care system in Taiwan and China.The multicenter palliative care discussion forum began 1997 and 2010 in Taiwan and China, respectively. In every forum, 1 to 2 cases were presented by multiple field specialists, and multi-dimensional problems were discussed. All of these case reports and reference materials from the forums were analyzed.The conference discussed 199 and 143 cases in Taiwan and China, including 172 and 143 cancer patients. The most common mentioned symptom was pain (66.3% in Taiwan, 96.95% in China). As time went on, the rate of discussion in pain management issues decreased, but the social and psycho-spiritual issues increased in Taiwan. After some major legal and social changes, the discussion of ethical issues increased rapidly. In China, the trends and ranking in discussion of nonpain management issues stabilized and showed most frequently in psycho-spiritual issues, followed by social, ethical and legal issues.Sharing palliative experience via tele-videoconferences is an effective tool to improve the quality of care, and also saves a significant amount of time and expense. Experts in different professions from different hospitals should discuss any palliative problems, share their valuable experience, and ponder a comprehensive hospice care.

Aspirin (ASA) exerts an anti-tumor effect via the COX pathway. Clinical studies on the chemopreventive effects of ASA on uterine cancer (UC) remain inconsistent. We used population-based retrospective cohort study to evaluate the UC in ASA users in Taiwanese women. From insurance claims data, we identified 23,342 women received ASA treatment between 2000 and 2010 and a comparison group of same sample size randomly selected from the same database matched by the propensity score. The incidence of UC in the ASA cohort was 10% of that in the comparison group (0.28 vs 2.73 per 10,000 person-years). The Poisson regression analysis estimated adjusted incidence rate ratio (IRR) was 0.10 (95% confidence interval (CI) = 0.09–0.11) for ASA users relatives to comparisons after controlling for covariates. The UC incidence in ASA users decreased with age, from 0.61 per 10,000 person-years in the 20 to 39 years old (adjusted IRR = 0.21, 95% CI = 0.15–0.29) to 0.21 per 10,000 person-years in the 65 to 80 years old (adjusted IRR = 0.15, 95% CI = 0.12–0.16). The incidence was higher in longer term users. Hormone therapy of estradiol was associated with the increase of UC risk in both cohorts, but less in ASA users than comparisons (1.34 vs 4.75 per 10,000 person-years). This study suggests that ASA use was associated with a decreased risk of UC. Further prospective randomized clinical trials are warranted to confirm the association.

This study compared the surgical outcomes of two surgical methods for treating multilevel cervical spondylotic myelopathy (MCSM) combined with cervical kyphotic deformity (CKD): (1) the ELTA method consisted of expansive open-door laminoplasty (EOLP) followed by three-segment anterior cervical discectomy fusion (ACDF), and (2) the LAPI method consisted of long-segment ACDF followed by long-level posterior instrumented fusion (PIF). Surgical treatment of CKD combined with MCSM remains challenging. Surgical considerations should include adequate spinal cord decompression and restoration of satisfactory cervical sagittal alignment (CSA). In certain situations, a solid PIF structure is vital to prevent failure. We included 105 patients who underwent the aforementioned surgical methods for MCSM combined with CKD from January 2013 to December 2017. The minimum follow-up period was 1 year. Comparative analysis was performed to compare the two surgical strategies’ preoperative and postoperative functional outcomes, including a visual analog scale for neck pain, neck disability index, the Japanese Orthopedic Association cervical myelopathy score, and the Nurick score, as well as the CSA radiographic outcomes, including C2-7 Cobb angle, C2-7 sagittal vertical axis, and C7 slope. The risk factors related to reduced improvement in functional status were analyzed. A total of 63 patients underwent ELTA and 42 patients underwent LAPI. Improvements in functional outcomes were considerable in both groups. The mean C2-7 Cobb angle was restored from 7.4° ± 2.1° kyphosis to 8.8° ± 4.7° lordosis in the ELTA group and from 15.3° ± 4.2° kyphosis to 15.8° ± 8.1° lordosis in the LAPI group. The maximal correction angle was 22.6° in the ELTA group and 42.6° in the LAPI group. Although changes in CSA seemed to be significantly correlated with improvements of functional status, the ELTA and LAPI methods were both effective for treating MCSM combined with CKD, when appropriately selected. The ELTA method was indicated for MCSM patients who had a low degree of CKD, whereas the LAPI method was indicated for MCSM patients who had poor function scores and a high degree of CKD.

Previous studies have suggested that patients with psychotic or mental disorders are relatively pain insensitive, resulting in difficulties in the diagnosis of acute intra-abdominal diseases requiring emergency surgeries. We aimed to evaluate whether central nervous system (CNS) or mental disorders are associated with perforated appendicitis in patients with acute appendicitis. We conducted a population-based case-control study using Taiwan's National Health Insurance Research database. Patients aged >18 years who had been hospitalized with a diagnosis of acute appendicitis between 2000 and 2013 were identified. After 1:1 matching for age and sex, 2792 patients with perforated appendicitis (case group) and 2792 patients with nonperforated appendicitis (control group) were included. CNS disorders, mental disorders, pain control medication, and several comorbidities were analyzed for the odds of appendiceal perforation with 95% confidence interval (CI) using the multivariable logistic regression model. Schizophrenia and dementia were associated with a high risk of appendiceal rupture in patients with acute appendicitis, with an adjusted odds ratio of 2.01 for dementia (95% CI: 1.19–3.39, P = .009) and 4.8 for schizophrenia (95% CI: 1.62–14.19, P = .005). Other factors, such as other CNS disorders, comorbidities, and pain control medication, were not associated with the risk of perforated appendicitis. Dementia and schizophrenia are associated with perforated appendicitis in patients with acute appendicitis. This might be owing to altered pain perception, difficult symptom expression, and delayed hospitalization. Further studies are still needed to determine the underlying mechanism and confirm the causality.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder among the women of reproductive age. We conducted a nationwide population-based retrospective cohort study to analyze the association between PCOS and the subsequent development of gynecological cancers, namely endometrial, breast, and ovarian cancer. For this population-based cohort study, we used the Taiwan National Health Insurance Research Database, which contains information on approximately 24.7 million insured individuals. The cohort included women who had received a diagnosis of PCOS between 1998 and 2013. An age-matched systematic random-sampling method with a ratio of 1:4 was used for patient selection for the non-PCOS reference cohort. Multivariate Cox proportional hazard regression analysis was used to determine the effects of PCOS on the risks of gynecologic and breast cancer. The data are presented as hazard ratios (HRs) with 95% confidence intervals (CIs). The PCOS cohort consisted of 8155 patients with PCOS, and the comparison cohort consisted of 32,620 matched patients without PCOS. The incidence of endometrial cancer was 226 and 15 per 100,000 person-years in the PCOS and comparison groups, respectively. A statistically significant higher risk of endometrial cancer was found in the PCOS cohort (adjusted HR [aHR] = 17.7, 95% CI = 4.9–64.2) than in the comparison cohort. However, no association was observed between PCOS and ovarian (aHR = 1.64, 95% CI: 0.63–4.27) or breast cancer (aHR = 0.98, 95% CI: 0.58–1.65). The results of this large population-based cohort study supported the premise that women with PCOS might have an increased risk of endometrial cancer, but no association between PCOS and the risks of ovarian and breast cancer was found.

Studies on the relationship between gynecologic surgery and subsequent ovarian cancer have been carried out in limited Western ethnic groups. We aim to evaluate whether receiving hysterectomy and/or salpingectomy associated with ovarian cancer risk in Taiwan. From the Taiwan National Health Insurance Research Database, we identified a gynecologic surgery cohort consisting of women who had newly received hysterectomy (N = 181,151), salpingectomy (N = 45,410) or both hysterectomy and salpingectomy (N = 11,875) in 2000 to 2013. A comparison cohort of 953,744 women was randomly selected from women without the surgeries, frequency-matched by age and index date of the surgery case. They were followed up to identify subsequent ovarian cancer by the end of 2013. The overall ovarian cancer incidence was 4.4-fold greater in the gynecologic surgery cohort than in the comparison cohort (41.5 vs 9.43 per 106 person-years) with an adjusted hazard ratio of 3.86 (95% confidence interval = 2.56–5.84). Women with both hysterectomy and salpingectomy had the highest incidence and followed by women with hysterectomy or salpingectomy (52.5, 45.5, or 23.3 per 106 person-years, respectively). No ovarian cancer was noted in the subgroup with bilateral salpingectomies. We conclude that women with gynecologic surgery of hysterectomy and/or salpingectomy are at an increased risk of developing ovarian cancer, particularly among women who have had other gynecologic comorbidity. Women with gynecologic surgery and comorbidity deserve greater attention to prevent and screen for ovarian cancer.

Although the optimal treatment for femur shaft fracture is intramedullary nailing fixation, nonunion still occurs. We determined the oligotrophic nonunion rate among femur fractures managed operatively and identified risk factors for reoperation. This was a retrospective clinical study. The data of the patients between 40 and 70 years old with diaphyseal femur fracture who have received reamed and interlocked intramedullary nailing fixation in our hospital from February 2014 to April 2018 were collected. They were followed at regular intervals for at least 1 year after the operation. The primary outcome was nonunion of the fracture site that required reoperation in accordance with the radiographic union scale for tibial shaft fracture (RUST), which is a reasonable score system for lower limb diaphyseal fracture. Three of them were hypertrophic nonunion (1.9%) and the other 13 cases were oligotrophic nonunion (8.6%) at postoperative 12 months follow-up. All of the postoperative plain films showed adequate reduction quality. The three hypertrophic nonunion cases were all obese male with fracture site comminution. Fracture at the proximal third junction, hypertension (HTN) and diabetes mellitus (DM) was significantly associated with oligotrophic nonunion of the fracture site from logistic regression analysis. The mean RUST score 3 months after the operation was not significantly different between the union group and nonunion group but was significantly lower 6 months after the operation in the nonunion group. In conclusion, intramedullary nailing of the femur shaft fractures was associated with a low risk of nonunion at the 1-year follow-up in the middle age group. Those with comorbidity such as obese, HTN, and DM, with fracture site at the proximal third junction or comminution should be followed up closely and rehabilitation with cause aggressively. Radiographic scale as the RUST score at postoperative 6 months could be used to predict this complication.

Hysterectomy is a common procedure for benign pathologies of the uterus. Reduced production of estrogen following hysterectomy has been reported. Yet the association between hysterectomy and coronary artery disease (CAD) risk remains controversial. The aim of this study was to investigate the effect of hysterectomy on the risk of CAD; calculations were adjusted for traditional risk factors. This study used a 1 million patient cohort of the Taiwan National Health Insurance database and included a total of 7331 women who received hysterectomy from 2000 to 2013. We randomly selected a control group composed of 29,324 women without hysterectomy by 1:4 matching the age (exact year) with the hysterectomy group. The mean (standard deviation) age was 43.5 ± 4.0 in the hysterectomy and 43.6 ± 4.0 in the control group. A total of 1986 CAD cases developed in both groups during a median follow-up of 7 years. Significant differences were observed in CAD incidence in the hysterectomy versus control group (9.82 vs. 7.17/1000 person-years, P

Neurilemmoma commonly occurs from the fourth to sixth decades of life with an incidence of 3 to 10 per 100,000 people, and is rare in adolescence. This case report describes the clinical and radiographic features of 2 rare cases with intraspinal neurilemmoma of the cervical and thoracic spine. A 29-year-old man who experienced middle back pain with prominent right lower limb weakness, and an 11-year-old boy who suffered from sudden onset neck pain with left arm weakness and hand clawing for 2 weeks before admission to our department were included in this case report. Magnetic resonance imaging of both patients revealed an intraspinal mass causing spinal cord compression at the cervical and thoracic spine. The patients subsequently received urgent posterior spinal cord decompression and tumor resection surgery. The histopathology reports revealed neurilemmoma. The 2 patients recovered and resumed their normal lives within 1 year. Intraspinal neurilemmoma is rare but should be considered in the differential diagnosis of spinal cord compression. Advances in imaging techniques and surgical procedures have yielded substantially enhanced clinical outcomes in intraspinal neoplasm cases. Delicate preoperative study and surgical skill with rehabilitation and postoperative observation are critical.
