Both statins and magnesium are associated with NMDA receptors and anti-inflammatory effect. Peripheral NMDA receptors are known to be involved in inflammationinduced pain. This study aimed to investigate the impact of perioperative use of a statin– magnesium combination on opioid consumption in patients who underwent cardiac surgery. This was a retrospective study of 542 patients who underwent cardiac surgery. The patients were divided into two groups according to statin use: the statin–magnesium group (n=375) and the magnesium-only group (n=167). Patients in the magnesium- only group received only perioperative magnesium, but no statins, to prevent atrial fibrillation following cardiac surgery. After propensity-score matching, 228 patients (n=114 in each group) were analyzed to investigate opioid consumption, visual analogue scale (VAS) pain scores over a 72-h period, and pain outcomes according to the duration of statin treatment (<1 or ≥1 yr). The consumed opioid volume was significantly smaller in statin–magnesium group than the magnesium-only group, both before (p=0.010) and after matching (p=0.017). The statin–magnesium combination did not significantly reduce the VAS pain scores compared with magnesium alone. Although the statin–magnesium combination did not significantly reduce the pain intensity compared with magnesium alone, the combination therapy was effective in reducing opioid consumption after surgery.

Background: Fever is a common cause of pediatric consultation in the emergency department. However, identifying the source of infection in many febrile infants is challenging because of insufficient presentation of signs and symptoms. Meningitis is a critical cause of fever in infants, and its diagnosis is confirmed invasively by lumbar puncture. This study aimed to evaluate potential laboratory markers for meningitis in febrile infants. Methods: We retrospectively analyzed infants aged <3 months who visited the emergency department of our hospital between May 2012 and May 2017 because of fever of unknown etiology. Clinical information and laboratory data were evaluated. Receiver operating characteristic (ROC) curves were constructed. Results: In total, 145 febrile infants aged <3 months who underwent lumbar punctures were evaluated retrospectively. The mean C-reactive protein (CRP) level was significantly higher in the meningitis group than in the non-meningitis group, whereas the mean white blood cell count or absolute neutrophil count (ANC) did not significantly differ between groups. The area under the ROC curve (AUC) for CRP was 0.779 (95% confidence interval [CI], 0.701–0.858). The AUC for the leukocyte count was 0.455 (95% CI, 0.360–0.550) and that for ANC was 0.453 (95% CI, 0.359–0.547). The CRP cut-off value of 10 mg/L was optimal for identifying possible meningitis. Conclusion CRP has an intrinsic predictive value for meningitis in febrile infants aged <3 months. Despite its invasiveness, a lumbar puncture may be recommended to diagnose meningitis in young, febrile infants with a CRP level >10 mg/L.

Thrombotic thrombocytopenic purpura (TTP) can cause serious morbidity and mortality, and differentiating between this disease and systemic lupus erythematosus (SLE) can prove challenging. Although rare, TTP accompanied by SLE is linked to several complications and a higher mortality rate. Herein, we report a case of a 16-year-old boy who presented with systemic symptoms, such as petechiae, and was diagnosed with acquired TTP following a laboratory test. Steroid treatment was initiated and a diagnosis of SLE was reached after the symptoms had improved. Treatment with low-dose prednisone in addition to hydroxychloroquine was continued. The patient did not develop renal failure or neurologic deficit. No specific symptoms were observed after treatment and during the follow-up period. Early treatment of SLE is crucial, but it is difficult to reach an early diagnosis because the symptoms are similar to those of TTP. In the current study, an early diagnosis of TTP led to prompt treatment, thereby avoiding the fatal symptoms that could be caused by SLE.

BACKGROUND: More remifentanil and less propofol may speed up the early recovery from anesthesia. This study evaluated the hemodynamic response and recovery profile of high-dose remifentanil/lowdose propofol anesthesia, compared with low-dose remifentanil/highdose propofol anesthesia for lower abdominal surgery. METHODS: Sixty women undergoing lower abdominal surgery were randomly assigned to either groups H or L. Anesthesia was maintained with remifentanil 0.5 micro/kg/min and propofol 4 mg/kg/h in group H, or with remifentanil 0.25 micro/kg/min and propofol 8 mg/kg/h in group L. The heart rate, blood pressure, and EEG bispectral index (BIS) score were recorded. At the end of surgery, the anesthetic agents were discontinued, and the early emergence, recovery, and side effects were assessed. RESULTS: In both groups, the heart rate and systolic blood pressure were decreased over time compared with the preanesthetic baseline values (P < 0.05) but there were no differences between the two groups. The frequency of hemodynamic events (hypertension, hypotension, and bradycardia) and their rescue drugs were similar in the two groups. The BIS scores were lower during anesthesia in group L than in group H (P < 0.05). The time to spontaneous ventilation, eye opening on verbal command, extubation, orientation, and full recovery were faster in group H than in group L (P < 0.05). The incidences of side effects were similar in both groups. CONCLUSIONS: In lower abdominal surgery, high-dose remifentanil/ low-dose propofol anesthesia offers faster recovery than low-dose remifentanil/high-dose propofol anesthesia. However, there were no differences in the hemodynamic changes and side effects between the groups.

BACKGROUND: Night shift work has well-known adverse effects on health. However, few studies have investigated the relationship between thyroid diseases and night shift work. This study aimed to examine night shift workers and their changes in thyroid stimulating hormones (TSH) levels over time. METHODS: Medical check-up data (2011–2015) were obtained from 967 female workers at a university hospital in Incheon, Korea. Data regarding TSH levels were extracted from the records, and 2015 was used as a reference point to determine night shift work status. The relationships between TSH levels and night shift work in each year were analyzed using the general linear model (GLM). The generalized estimating equation (GEE) was used to evaluate the repeated measurements over the 5-year period. RESULTS: The GEE analysis revealed that from 2011 to 2015, night shift workers had TSH levels that were 0.303 mIU/L higher than the levels of non-night shift workers (95 % CI: 0.087–0.519 mIU/L, p = 0.006) after adjusting for age and department. When we used TSH levels of 4.5 ≥ mIU/L to identify subclinical hypothyroidism, night shift workers exhibited a 1.399 fold higher risk of subclinical hypothyroidism (95 % CI: 1.050–1.863, p = 0.022), compared to their non-night shift counterparts. CONCLUSIONS: This result of this study suggests that night shift workers may have an increased risk of thyroid diseases, compared to non-night shift workers.

Stress-induced cardiomyopathy or Takotsubo cardiomyopathy is a recently described clinical entity which is associated with a chest pain occurring during a stress, an abnormal ECG and/or an increase in the troponin blood level and a transient left ventricular dysfunction. Transient left ventricular dysfunction generally involves the midsection and the apex of the heart with an akinesis. We reported a case of a 55-year-old female patient who developed a stress-induced cardiomyopathy after local epinephrine use during ophthalmologic surgery.

PURPOSE: Hypernatremia most frequently occurs in the immature newborn and be severe in association with intraventricular hemorrhage (IVH). This study examined the frequency, onset and risk factors of hypernatremia, and the relationship between hypernatremia and IVH in very low birth weight (VLBW; <1,250 g) infants. METHODS: We retrospectively reviewed the medical records of 55 VLBW infants admitted between January 2006 and December 2009 to the neonatal intensive care unit of Wonkwang University Hospital and who survived over 7 days. Serum sodium concentration, sodium intake, fluid and weight loss, as suggested risk factors of hypernatremia, and the incidence of IVH were evaluated. The infants were divided into a hypernatremia group (> or =150 mEq/L) and nonhypernatremia group, and were compared. RESULTS: Incidence of hypernatremia in the VLBW infants was 52.7%, and mean starting time of hypernatremia was 2.8+/-1.3 days. There were no differences in the sodium and fluid intake between the two groups. Weight loss at day 3 after birth was significantly higher in the hypernatremia compared to the nonhypernatremia group (P<0.05); thereafter weight loss was non-significantly higher. The incidence of IVH in VLBW infants was 38.2%, and the difference between the two groups was not significant. CONCLUSION: Hypernatremia occurs commonly in VLBW infants and is most commonly caused by weight loss in the early days after birth. Incidence of IVH is not likely influenced by hypernatremia with marginally elevated sodium concentration.

BACKGROUND: The objective of this study was to explore whether individual variations in the concentration of growth factors (GFs) influence the biologic effects of platelet-rich plasma (PRP) on human mesenchymal stem cells (HMSCs). METHODS: The concentrations of 7 representative GFs in activated PRP (aPRP) were measured using ELISA. The effects of PRP on the proliferation and alkaline phosphatase (ALP) activity of HMSCs were examined using several concentrations of aPRP from 3 donors; the relationships between the GF levels and these biologic effects were then evaluated using 10% aPRP from 5 subgroups derived from 39 total donors. HMSCs were cultured in DMEM with the addition of aPRP for 4 or 12 days; then, DNA content and ALP activity were measured. RESULTS: The quantity of DNA increased significantly at a 10% concentration of aPRP, but the ALP activity was suppressed at this concentration of aPRP. The GF concentrations varied among donors, and 5 subgroups of characteristic GF release patterns were identified via cluster analysis. DNA levels differed significantly between groups and tended to be higher in groups with higher concentrations of transforming growth factor-beta1 (TGF-beta1) and platelet-derived growth factors (PDGFs). DNA quantity was positively correlated with TGF-beta1 concentration, and was negatively correlated with donor age. ALP activity was negatively correlated with PDGF-BB concentration. CONCLUSIONS: The varying GF concentrations may result in different biologic effects; thus, individual differences in GF levels should be considered for reliable interpretation of the biologic functions and standardized application of PRP.

Supernumerary derivative (22) syndrome is a rare genomic syndrome. It is characterized by severe mental retardation, microcephaly, failure to thrive, preauricular tag or sinus, ear abnormalities, cleft and/or high-arched palate, micrognathia, kidney abnormalities, congenital heart defects, and genital abnormalities in males. In 99% of the cases, one of the parents is a balanced carrier of a translocation between chromosome 11 and chromosome 22. To date, there have been about 100 case reports of supernumerary derivative (22) syndrome. In most of the cases, supernumerary derivative (22) syndrome was the result of 3:1 meiotic segregation in the maternal 11;22 translocation carrier. We now report a case of 47,XX, + der(22)t(11;22)(q23;q11.2) resulting from 3:1 meiotic segregation of the paternal translocation carrier.
