Abstract
Neonatal diabetes mellitus (NDM) is a rare type of monogenic diabetes. At present, most published studies have focused on the types of gene mutations associated with NDM and the therapeutic effect of sulfonylureas (SUs) on the disease; few studies on NDM-associated intracranial hemorrhage (ICH) exist. In addition, p.V59M mutations generally lead to intermediate DEND (iDEND: intermediate developmental delay and neonatal diabetes) syndrome without epilepsy. Here, we present a case of a 1-month-old male infant who was diagnosed with NDM caused by a KCNJ11 missense mutation (p.V59M), presenting with cerebral injury. In the early stage of the disease, continuous insulin dose adjustment did not achieve an ideal level of blood glucose. Although blood glucose was subsequently controlled by oral SUs, which were administered after the genetic test result, the patient still displayed epilepsy and developmental delay. In this case report, we present our experience in the treatment of the infant, switching from insulin to oral SUs and we thought that SUs have limited effects on improving the prognosis of neurodevelopmental disturbances in NDM with foci of encephalomalacia. In addition, there may be a relationship between KCNJ11 missense mutations and cerebral injury, and further research must be carried out to confirm these points.

Abstract
OBJECTIVE Neonatal diabetes mellitus (NDM) may be transient or permanent, and the majority is caused by genetic mutations. Early diagnosis is essential to select the patients who will respond to oral treatment. In this investigation, we aimed to present the phenotype and genotype of our patients with NDM and share our experience in a single tertiary center METHODS A total of 16 NDM patients from 12 unrelated families are included in the study. The clinical presentation, age at diagnosis, perinatal and family history, consanguinity, gender, hemoglobin A1c, C-peptide, insulin, insulin autoantibodies, genetic mutations, and response to treatment are retrospectively evaluated. RESULTS The median age at diagnosis of diabetes was five months (4 days-18 months) although six patients with a confirmed genetic diagnosis were diagnosed >6 months. Three patients had KCNJ11 mutations, six had ABCC8 mutations, three had EIF2AK3 mutations, and one had a de novo INS mutation. All the permanent NDM patients with KCNJ11 and ABCC8 mutations were started on sulfonylurea treatment resulting in a significant increase in C-peptide level, better glycemic control, and discontinuation of insulin. CONCLUSION Although NDM is defined as diabetes diagnosed during the first six months of life, and a diagnosis of type 1 diabetes is more common between the ages of 6 and 24 months, in rare cases NDM may present as late as 12 or even 24 months of age. Molecular diagnosis in NDM is important for planning treatment and predicting prognosis. Therefore, genetic testing is essential in these patients.

Abstract
OBJECTIVES Diabetes mellitus (DM) is a major chronic metabolic disease in the world, and the prevalence has been increasing rapidly in recent years. The channel of KATP plays an important role in the regulation of insulin secretion. The variants in ABCC8 gene encoding the SUR1 subunit of KATP could cause a variety of phenotypes, including neonatal diabetes mellitus (ABCC8-NDM) and ABCC8-induced nonneonatal diabetes mellitus (ABCC8-NNDM). Since the features of ABCC8-NNDM have not been elucidated, this study is aimed at concluding the genetic features and clinical characteristics. METHODS We comprehensively reviewed the literature associated with ABCC8-NNDM in the following databases: MEDLINE, PubMed, and Web of Science to investigate the features of ABCC8-NNDM. RESULTS Based on a comprehensive literature search, we found that 87 probands with ABCC8-NNDM carried 71 ABCC8 genetic variant alleles, 24% of whom carried inactivating variants, 24% carried activating variants, and the remaining 52% carried activating or inactivating variants. Nine of these variants were confirmed to be activating or inactivating through functional studies, while four variants (p.R370S, p.E1506K, p.R1418H, and p.R1420H) were confirmed to be inactivating. The phenotypes of ABCC8-NNDM were variable and could also present with early hyperinsulinemia followed by reduced insulin secretion, progressing to diabetes later. They had a relatively high risk of microvascular complications and low prevalence of nervous disease, which is different from ABCC8-NDM. CONCLUSIONS Genetic testing is essential for proper diagnosis and appropriate treatment for patients with ABCC8-NNDM. And further studies are required to determine the complex mechanism of the variants of ABCC8-NNDM.

Abstract
OBJECTIVE A precision medicine approach is used to improve treatment of patients with monogenic diabetes. Herein, we searched SU efficiency according to the genotype-phenotype correlation, dosage used, and side effects. RESEARCH DESIGN AND METHODS Systematic review conducted according the PRISMA control criteria identifying relevant studies evaluating the in vivo and in vitro sensitivity of ATP-dependent potassium channels according to the characteristics of genetic mutation. RESULTS Hundred and three selected articles with complete data in 502 cases in whom 413 (82.3%) had mutations in KCNJ11 (#64) and 89 in ABCC8 (# 56). Successful transfer from insulin to SU was achieved in 91% and 86.5% patients, respectively, at a mean age of 36.5 months (0-63 years). Among patients with KCNJ11 and ABCC8 mutations 64 and 46 were associated with constant success, 5 and 5 to constant failure, and 10 and 4 to variable degrees of reported success rate, respectively. The glibenclamide dosage required for each genotype ranged from 0.017 to 2.8 mg/kg/day. Comparing both the in vivo and in vitro susceptibility results, some mutations appear more sensitive than others to sulfonylurea treatment. Side effects were reported in 17/103 of the included articles: mild gastrointestinal symptoms and hypoglycaemia were the most common. One premature patient had an ulcerative necrotizing enterocolitis which association with SU is difficult to ascertain. CONCLUSIONS Sulfonylureas are an effective treatment for monogenic diabetes due to KCNJ11 and ABCC8 genes mutations. The success of the treatment is conditioned by differences in pharmacogenetics, younger age, pharmacokinetics, compliance, and maximal dose used.

Abstract
BACKGROUND The effect of naproxen on the treatment of neoplastic fever is still unclear. A systematic review and meta-analysis were performed to investigate the effect of naproxen in the treatment of cancer fever or suspicion. Besides, the latest and most convincing evidence was provided for the earlier use of naproxen in treating cancer patients with fever of unknown origin. METHODS A literature review was conducted to identify all published studies on the naproxen for the treatment of neoplastic fever. Electronic databases (eg, PUBMED, EMBASE and the Cochrane Library) were searched until October 2018. Data were extracted, and the risk of bias was assessed by 2 authors independently. Standard meta-analyses on the rate of successful treatment were conducted using a random-effects model, and relative risks were calculated with 95% confidence intervals (CIs). RESULTS A total of 15 studies, recruiting 582 participants, were included, which were 1 randomized controlled trial (RCT), 1 non-RCT, 3 cross-sectional studies, and 10 case-series studies. The result of our meta-analysis revealed that the success rate on the treatment of neoplastic fever using naproxen was 94.1% (95% CI: 87.6%-97.3%). The success rate of the suspected neoplastic fever was 79.8%; for fever of unknown origin, it also reached 67.7%. In this meta-analysis, the success rate was 98.1% (95% CI: 95.0%-99.3%) in the dosage of 250 mg twice a day. Besides, a small dose of 125 mg naproxen, 375 mg twice a day and 250 mg 3 times a day were also useful. The result of the subgroup analysis revealed that the difference was not statistically significant in the treatment success rate for solid tumors and hematologic malignant. CONCLUSIONS The result of our meta-analysis suggested that naproxen exhibited a highly successful rate for the treatment of neoplastic fever. Besides, naproxen was also satisfactory in improving symptoms of suspected neoplastic fever and fever of unknown origin. The earlier use of naproxen might be able to mitigate cancer patient's suffering and enhanced their quality of life. These findings, however, rely primarily on observational data and should be interpreted rigorously. Further well-conducted trials are required to assess naproxen for the treatment of neoplastic fever.

Abstract
Diabetes mellitus and impaired fasting glucose associated with single gene mutations are less rare than previously thought and may account for more than 6% of patients attending a pediatric diabetes clinic. The number of loci involved in monogenic diabetes exceed 25, and appropriate genetic diagnosis is crucial to direct therapy, for genetic counseling and for prognosis of short- and long-term complications. Among patients with neonatal diabetes (i.e. with onset within first 6 months of life) and patients with Maturity Onset Diabetes of the Young (MODY; an autosomal dominant form of diabetes), those carrying mutations in KCNJ11, ABCC8, HNF1A and HNF4A genes usually respond to oral therapy with sulphonylurea, while those bearing GCK mutations do not necessitate any treatment. Sensor-augmented continuous subcutaneous insulin infusion has been successfully employed in neonatal diabetes, and long-lasting effectiveness of sulfonylurea in KCNJ11 mutation carriers with neonatal diabetes well documented.
