The American Diabetes Association (ADA), European Association for the Study of Diabetes (EASD), Joint British Diabetes Societies for Inpatient Care (JBDS), American Association of Clinical Endocrinology (AACE) and Diabetes Technology Society (DTS) convened a panel of internists and diabetologists to update the ADA consensus statement on hyperglycaemic crises in adults with diabetes, published in 2001 and last updated in 2009. The objective of this consensus report is to provide up-to-date knowledge about the epidemiology, pathophysiology, clinical presentation, and recommendations for the diagnosis, treatment and prevention of diabetic ketoacidosis (DKA) and hyperglycaemic hyperosmolar state (HHS) in adults. A systematic examination of publications since 2009 informed new recommendations. The target audience is the full spectrum of diabetes healthcare professionals and individuals with diabetes.

OBJECTIVE: The literature about oral manifestations and dental management in maple syrup urine disease (MSUD) is sparse. The aim of this report is to present a new case of MSUD with special emphasis on oral findings and to review the relevant literature.
METHODS: A case report of a 4-year-old boy with MSUD was described according to the CARE guidelines for describing case reports. Scoping review of relevant literature was performed, according to the PRISMA-ScR guidelines, by searching PubMed, Medline, Embase, and the grey literature for articles describing dental management and/or oral manifestations in MSUD.
RESULTS: The initial search identified 219 articles, but only 4 met the inclusion criteria. Rampant caries and plaque induced gingivitis were the main oro-dental findings in MSUD. Other oral findings included enamel hypoplasia, skeletal abnormalities, and abnormal oral behaviors. Disease-related factors appeared to play a major role in the development of the observed oral phenotype.
CONCLUSIONS: Oral health in MSUD seems to be influenced by the reliance on semi-synthetic diet and associated neurocognitive complications. Tailored oral health promotional interventions should be included in the multidisciplinary management of patients with MSUD.

Idiopathic ketotic hypoglycemia (IKH) is defined as bouts of hypoglycemia with increased blood or urine ketones in certain children after prolonged fasting or during illness. IKH is divided into physiological IKH, which is most frequently observed in normal children with intercurrent acute illness, and pathological IKH, which occurs in children who lack counter-regulatory hormones, have a metabolic disease, or have Silver-Russell syndrome. The typical patient is a young child between the ages of 10 months and 6 years. Episodes nearly always occur in the morning after overnight fasting. Symptoms include those of neuroglycopenia, ketosis, or both. IKH may be diagnosed after ruling out various metabolic and hormonal conditions associated with ketotic hypoglycemia. Sufficient amounts of carbohydrates and protein, avoidance of prolonged fasting, and increased frequency of food ingestion are the main modes of treating IKH. It is crucial to understand the pathogenesis of IKH and to distinguish physiological IKH from pathological IKH. In this mini-review, we present a brief summary of IKH in terms of its definition, types, clinical presentation, diagnosis, and therapeutic approach in children.

This single centre case series describes the presentation and management of six cases of peripartum hyponatraemia in women who were otherwise deemed low-risk at delivery. It highlights presenting symptoms such as fatigue, confusion and seizures as well as the effects on the neonate. It also focuses on areas of interest such as fluid intake, hormonal effects of ADH and oxytocin and the association with birthing pools for future research.

Urinalysis is a widely used diagnostic tool to assist clinicians in determining the etiology of various acute or chronic pathologies. Primary care, general internal medicine, and family medicine clinicians should be adept at identifying indications for urinalyses, in addition to appropriately interpreting their results. In this article, we provide an overview of urinalysis for non-nephrologists.

BACKGROUND: Hyperemesis gravidarum(HEG) is one of the severe health problems in early pregnancy. Obstetricians should be aware of systemic inflammation in HEG patients to provide better preventive strategies.
OBJECTIVE: Hyperemesis gravidarum(HEG) is one of the most common causes of hospitalization in early pregnancy. Complete blood count parameters can be used as inflammatory markers in patients with HEG. We aimed to investigate the Systemic Immune-Inflammation Index (SII)in predicting the severity of HEG.
METHODS: This cross-sectional study was performed with 469 pregnant women diagnosed and hospitalized with HEG. The study parameters were calculated from complete blood count tests and urine analysis. Demographic characteristics, the Pregnancy Unique Quantification of Emesis (PUQE) scale values, and ketonuria levels at hospital admission were recorded. The neutrophil‑to‑lymphocyte ratio (NLR), platelet‑to‑lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and SII, calculated by the formula (neutrophil × platelet/lymphocyte), were evaluated for predicting the severity of HEG.
RESULTS: There was a positive correlation between the increased degree of ketonuria and SII. The cut-off value of SII for predicting the severity of HEG was 1071.8 (AUC 0.637, 95% CI (0.582-0.693), p<0.001), and sensitivity and specificity were 59% and 59%, respectively. The cut-off value of SII to predict the length of hospitalization was 1073.6(AUC: 0.565, 95% CI: (0.501-0.628), p = 0.039); sensitivity and specificity were 56.3% and 55.5%, respectively.
CONCLUSIONS: The clinical utility of SII in predicting HEG severity is limited due to relatively low sensitivity and specificity. Further research is needed to determine the importance of inflammatory indices in HEG patients.

OBJECTIVE: Hyperemesis gravidarum is an illness that starts in early pregnancy and manifests itself with oral intake problems, electrolyte imbalance, ketonuria, and weight loss. Inflammation is closely associated with the hyperemesis gravidarum, and inflammatory indicators have been studied to understand its pathophysiology. This study investigates the relationship of ketonuria levels with inflammatory markers platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and neutrophil-to-lymphocyte ratio (NLR) for hyperemesis gravidarum patients.
METHODS: This retrospective case control study was conducted at Kütahya Medical Sciences University Tertiary Research and Training Hospital between December 2019 and December 2020. A total of 173 pregnancies, 82 of them with hyperemesis gravidarum and 91 of them low-risk pregnancies were included in the study. The patients\' demographic profiles and laboratory parameters were recorded. The patients were divided into hyperemesis gravidarum and control groups and the groups were compared for the levels of inflammation markers. For the hyperemesis gravidarum group, the relationship between ketonuria levels and the inflammation severity was investigated.
RESULTS: MLR, NLR, PLR levels were higher in the hyperemesis gravidarum group than the control group in a statistically significant way (p < 0.001 for all of the comparisons). The hyperemesis gravidarum group was subdivided into four groups based on their ketonuria levels, and their MLR, NLR, PLR levels were compared. The differences between the groups were statistically significant (p < 0.001) and the indicators increased with the ketonuria levels. Finally, ketonuria levels had a positive and significant correlation with MLR (rho =0.67, p < 0.001), PLR (rho =0.67, p < 0.001), and NLR (rho =0.8, p < 0.001).
CONCLUSIONS: Hyperemesis gravidarum patients have higher levels of hematologic inflammation indicators than healthy pregnant patients. For these patients, the levels of the indicators increase with ketonuria levels.

OBJECTIVE: To assess the association between ketonuria and hyperemesis gravidarum (HG) disease severity.
METHODS: We included pregnant women hospitalised for HG who participated in the Maternal and Offspring outcomes after Treatment of HyperEmesis by Refeeding (MOTHER) trial and women who were eligible, chose not to be randomised and agreed to participate in the observational cohort. Between October 2013 and March 2016, in 19 hospitals in the Netherlands, women hospitalised for HG were approached for study participation. The presence of ketonuria was not required for study entry. Ketonuria was measured at hospital admission with a dipstick, which distinguishes 5 categories: negative and 1+ through 4 + . The outcome measures were multiple measures of HG disease severity at different time points: 1) At hospital admission (study entry): severity of nausea and vomiting, quality of life and weight change compared to pre-pregnancy weight, 2) One week after hospital admission: severity of nausea and vomiting, quality of life and weight change compared to admission, 3) Duration of index hospital admission and readmission for HG at any time point RESULTS: 215 women where included. Ketonuria was not associated with severity of nausea and vomiting, quality of life or weight loss at hospital admission, nor was the degree of ketonuria at admission associated with any of the outcomes 1 week after hospital admission. The degree of ketonuria was also not associated with the number of readmissions. However, women with a higher degree of ketonuria had a statistically significant longer duration of hospital stay (per 1+ ketonuria, difference: 0.27 days, 95 % CI: 0.05 to 0.48).
CONCLUSIONS: There was no association between the degree of ketonuria at admission and severity of symptoms, quality of life, maternal weight loss, or number of readmissions, suggesting that ketonuria provides no information about disease severity or disease course. Despite this, women with a higher degree of ketonuria at admission were hospitalised for longer. This could suggest that health care professionals base length of hospital stay on the degree of ketonuria. Based on the lack of association between ketonuria and disease severity, we suggest it has no additional value in the clinical management of HG.

BACKGROUND: Recently, new concepts about obesity and normal weight subtypes with metabolic conditions are rising and ketone bodies are emerging as a significant indicator of metabolic health. This study aimed to find a relationship between ketonuria and those subtypes.
METHODS: The data of 19,036 subjects were analyzed in this cross-sectional study (2013-2017 Korea National Health and Nutrition Examination Survey, KNHANES). Based on body mass index and adult treatment panel III with modification of waist circumference, individuals were categorized into 4 groups: metabolically healthy normal weight (MHNW), metabolically healthy obese (MHO), metabolically unhealthy normal weight (MUNW), and metabolically unhealthy obese (MUO). Individuals were divided into 2 groups, positive and negative ketonuria groups, and the metabolic parameters were compared.
RESULTS: The metabolic indicators of the positive ketonuria group showed better results than those of the negative ketonuria group and the MHNW group showed the highest proportion of positive ketonuria. The MHNW group showed higher urinary ketones than the MUO group (odds ratio [OR], 0.391; 95% confidence interval [CI], 0.254-0.601) in men. In women, OR of having ketonuria was 0.698 (95% CI, 0.486-1.002) in the MHO group and 0.467 (95% CI, 0.226-0.966) in the MUNW group compared to the MHNW group, respectively.
CONCLUSIONS: Compared to the MHNW group, the MUO group showed lower presence of ketonuria in men, and tendency to have less ketonuria in women.

Ketosis is a metabolic situation involving an increase in blood and urine concentrations of ketones that, when prolonged, leads to acidosis. Moderate ketosis usually appears after a fast of a few hours, but its prolongation exposes to hyperketosis. Observation: A 25-year-old woman presented to the emergency department for cohercitive vomiting. She was fasting for a long time in a spiritual setting and had a restricted diet limited to water and vitamin supplements. Clinical and biological assessment was in favour of fasting ketoacidosis. Evolution was favorable with intravenous hydration, poly-ionic and micronutrient supplementation and a gradual resumption of oral feeding. Conclusion: We report the case of a patient with fasting ketoacidosis. Besides consequences of this ketoacidosis, the challenge was also in resuming oral feeding in order to avoid a potentially fatal inappropriate renutrition syndrome.
