An enigma of hypothyroidism and hyponatremia coexistence: a nationwide population-based retrospective study.

INTRODUCTION: Hypothyroidism is a rare and possible cause of hyponatremia. However, the clinical epidemiology and risk of mortality (ROM) when they coexist still remain elusive. OBJECTIVES: We assessed the epidemiology and ROM among index patients with coexisting hypothyroidism and hyponatremia via a national population database. PATIENTS AND METHODS: This retrospective cohort study utilized Taiwan's National Health Insurance program database. Distributions of definite sociodemographic factors were analyzed. The annual incidence among the overall group and sex-subgroups was investigated. In addition, potential factors influencing the ROM were also evaluated. RESULTS: Of 4,549,226 patients from 1998 to 2015, a total of 3,140 index patients with concurrent hypothyroidism and hyponatremia were analyzed. The incidence rate increased tenfold from 1998 to 2015; average annual incidence rate was 174. Among the total participants, 57.1% were women; mean age was 72.6 ± 14.7 years and 88.8% were aged > 55 years. Although average length of stay (LOS) was 13.1 ± 15.4 days, the mortality group had significantly longer LOS than that in the survival group (12.9 days vs 22.2 days). Old age, catastrophic illness, cardiac dysrhythmia, and low hospital hierarchy were independent predictors of hospital mortality. The optimal LOS cutoff value for ROM prediction was 16 days. Index patients with LOS > 16 days increased ROM by 2.3-fold. CONCLUSIONS: Coexistent hypothyroidism and hyponatremia is rare, although the incidence increased gradually. Factors influencing the ROM, such as old age, underlying catastrophic status, cardiac dysrhythmia, hospital hierarchy, and LOS should be considered in clinical care.

New dimension on potential factors of successful pediatric peripheral intravenous catheterization.

BACKGROUND: Peripheral intravenous catheterization (PIVC) is pivotal to pediatric medical care; however, it is a challenging technique for pediatricians, and the parameters affecting successful pediatric PIVC establishment have not been fully investigated. METHODS: This prospective observational study collected data from pediatric patients aged less than 18 years who required PIVC. The participants were categorized into five groups for subgroup analysis: newborn, infant, toddler, pre-school, and student (children and adolescent). Data on demography, biochemistry, and PIVC executors were examined to elucidate the most powerful factors affecting the success of PIVC. RESULTS: A total of 935 peripheral venous cannulations conducted within 1 year were studied. Age-subgroup analysis showed the highest failure rate (FR) of PIVC in the infant group (18.4%). No significant difference in BMI standard deviation score was noted among the groups (p-value = 0.430). Compared with those for the success group, more attempts, longer completion time, and more medical staff were needed for the failure group (all p-values < 0.05). A high serum procalcitonin level was correlated with an increased FR (p-value = 0.016). In addition, the success rate was positively associated with the seniority of the operators, except for the 3-year experienced R3 group (93.5%) showing a higher success rate than the 4-year experienced CR group (84.2%). CONCLUSIONS: Difficulty in setting up PIVC was the greatest in infants and even greater than that in newborns. Even though seniority was a cardinal factor in successful PIVC, a high FR was still noted despite the lack of continuous and steady practice.

Dual effects of a gonadotropin-releasing hormone agonist on an adolescent girl with pelvic congestion syndrome and precocious puberty: a case report.

Pelvic congestion syndrome (PCS) typically causes chronic non-cyclical abdominal pain with a considerable negative effect on the quality of life of women. However, pediatric cases with PCS are limited and non-invasive therapy for adolescent patients has not been reported. We report here a 13-year-old girl who presented with intermittent abdominal pain since the age of 2 years and her symptoms further deteriorated after breast development at 6 years and 9 months old. PCS and coexistent idiopathic central precocious puberty were finally diagnosed on the basis of tortuous ovarian and pelvic veins, and a pubertal response to a gonadotropin-releasing hormone (GnRH) test without hypothalamic-pituitary lesions. After treatment with the GnRH agonist, the pain score was greatly reduced and there was increased prediction of adult height. This case highlights the occurrence of PCS in adolescents and also indicates the role of non-invasive GnRH agonists in young patients with PCS before surgical intervention.

Phenotypic features of a microdeletion in chromosome band 20p13: A case report and review of the literature.

BACKGROUND: 20p13 microdeletion syndrome has been reported to be associated with developmental delays, intellectual disability, epilepsy, and unspecific dysmorphic characteristics. However, only a few cases of 20p13 microdeletion have been described, and therefore its typical features and precise pathogenesis remain elusive. METHODS AND RESULTS: In this article, we report the case of a 9-month-old infant who presented with a large fontanelle, facial dysmorphism, and failure to thrive. Array-comparative genomic hybridization (aCGH) analysis confirmed a 2.01-Mb microdeletion in chromosome band 20p13 that involved SOX12 and NRSN2, both of which are considered paramount causative genes in patients with 20p13 microdeletion. To elucidate the typical features of 20p13 microdeletion, we further reviewed these previously reported cases and found that motor delay (90%) was the most common manifestation, followed by language delay (60%), abnormal digits (60%), mental retardation (50%), large fontanelle (50%), electroencephalography abnormalities (50%), and seizure (40%). CONCLUSION: This report highlights the potential of aCGH as a practical and powerful tool with which to detect submicroscopic chromosomal abnormalities in individuals presenting with a wide spectrum of phenotypes, ranging from facial dysmorphism to failure to thrive. Additionally, the literature review casts new light on the clinical features of 20p13 microdeletion.

Is preoperative bowel preparation necessary for gynecological oncology surgery?

OBJECTIVE: We investigated the necessity of preoperative bowel preparation for gynecological oncology surgery. MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients who underwent gynecological oncology surgery with simultaneous colon or rectal resection between April 2005 and September 2014 at the Tri-Service General Hospital, Taipei, Taiwan. Patients were divided into two groups based on whether preoperative mechanical bowel preparation (MBP) was performed. Patient characteristics, including duration of antibiotic treatment, surgical procedures, and occurrence of surgical and nonsurgical complications, were compared. RESULTS: We enrolled 124 patients who underwent gynecological oncology surgery with simultaneous colon or rectal resection, of whom 76 received MBP and 48 did not receive mechanical bowel preparation. On comparison between the two groups, no significant differences were noted in the assessed patient characteristics, including mean age (p = 0.61), Federation of Gynecology and Obstetrics stage (p = 0.9), American Society of Anesthesiologists grade (p = 0.9), body mass index (p = 0.8), and residual tumor size (p = 0.86). Furthermore, duration of antibiotic treatment (p = 0.97), surgical procedures (p = 0.99), and total hospital days (p = 0.75), were not different between groups. The risk of surgical (p = 0.78) or nonsurgical (p = 1.0) complications was not significantly higher in the non-MBP group than in the MBP group. CONCLUSION: MBP provides no significant benefit during gynecological oncology surgery. Thus, preoperative MBP is not essential before gynecological oncology surgery and can be omitted.

Biofeedback relaxation for pain associated with continuous passive motion in Taiwanese patients after total knee arthroplasty.

Effective pain management is crucial for patient recovery after total knee arthroplasty (TKA). Biofeedback therapy, which encourages relaxation and helps alleviate various conditions associated with stress, may help to decrease postoperative pain in patients undergoing TKA. A quasi- experimental design was used to investigate the efficacy of a biofeedback relaxation intervention in reducing pain associated with postoperative continuous passive motion (CPM) therapy. Sixty-six patients admitted to a general hospital in Taiwan for TKA were recruited and randomly assigned to the intervention or control group. The intervention group received biofeedback training twice daily for 5 days, concurrent with CPM therapy, whereas the control group did not receive the biofeedback intervention. Pain was measured using a numeric rating scale before and after each CPM therapy session on postoperative days 1 through 5. The CPM-elicited pain score was calculated by subtracting the pre-CPM pain score from the post-CPM pain score. Results of repeated-measures analysis of variance showed intervention group reported significantly less pain caused by CPM than did the control group (f = 29.70, p < 0.001). The study results provide preliminary support for biofeedback relaxation, a non-invasive and non-pharmacological intervention, as a complementary treatment option for pain management in this population.
