RESUMO
The incidence of hypertriglyceridaemic pancreatitis is increasing. Hypertriglyceridaemia may be associated with false lowering of serum amylase and lipase in vitro. A retrospective study of serum lipase levels in 26 individuals who had acute pancreatitis diagnosed based on clinical criteria together with changes on computer tomography in the setting of severe hypertriglyceridaemia over a 5-year period from January 2017 to December 2021 was performed. Serum lipase levels were in the normal range in two patients (7.7%) and less than three times the upper end of the reference interval in 11 individuals (42%). Awareness of the potential for normal and nonsignificantly elevated serum lipase levels in the setting of hypertriglyceridaemic pancreatitis is important to avoid a missed diagnosis, to enable appropriate short- and long-term management and to prevent recurrent episodes.

BACKGROUND: Physiological changes in pregnancy may result in significant alterations in endocrine hormone profiles, serum and urine electrolytes and endocrine gland morphology on imaging. Pregnancy-specific pathophysiological processes may also affect the results for endocrine tests. Investigation of endocrine disorders in pregnancy requires knowledge of these changes and awareness of the safety of dynamic hormone testing and imaging for the mother and foetus. OBJECTIVE: This review seeks to outline the important physiological changes in pregnancy affecting reference intervals of basal and dynamic endocrine tests in pregnancy and the scenarios in which these changes are clinically significant, the pregnancy-specific disorders that may affect the investigation of endocrine disorders, and the safety of dynamic testing and imaging. CONCLUSION: Awareness of the effect of physiological changes, and the potential impact of pregnancy-specific disorders of endocrine tests, and the safety of imaging is crucial to the management of endocrine disorders in pregnancy.

BACKGROUND: Limited access to obstetrics and gynaecology (O&G) services in rural and remote Australia is believed to contribute to suboptimal birth outcomes. AIMS: To describe the characteristics of pregnancy aeromedical transfers, in-hospital outcomes, and patient access to O&G services, as compared to whole of Australia data. MATERIALS AND METHODS: We conducted a cohort study of women who required aeromedical retrieval for pregnancy-related issues between the 1 January 2015 and 31 December 2017. RESULTS: Hospital outcome data were collected on 2171 (65.2%) mothers and 2438 (100.0%) babies. The leading retrieval reason was threatened preterm labour and delivery (n = 883; 40.7%). Most patients were retrieved from rural and remote areas (n = 2224; 93.0%). Retrieved patients were significantly younger (28.0 vs 30.0 years, 95% CI 27.7-28.3), more likely to be overweight or obese (52.2% vs 45.1%, 95% CI 47.5-56.9) and to have smoked during their pregnancy (14.0% vs 9.9%, 95% CI 12.5-15.5) compared to Australian pregnant women overall. Over one-third of transferred women gave birth by Caesarean section (n = 812; 37.4%); the median gestational age at birth was 33.0 (95% CI 32.7-33.3) weeks. Early gestation is associated with low birth weights (median = 2579.5 g; 95% CI 2536.1-2622.9), neonatal resuscitation (35.4%, 95% CI 33.5-37.3), and special care nursery admission (41.2%, 95% CI 39.3-43.2). There were 42 (1.7%, 95% CI 1.2-2.2) stillbirths, which was significantly higher than seen Australia-wide (n = 6441; 0.7%). CONCLUSION: This study found that pregnant women retrieved by the Royal Flying Doctor Service were younger, with higher rates of obesity and smoking.

Profound physiological changes in the maternal cardiovascular system occur shortly after conception. These changes may impact upon the investigation of healthy and complicated pregnancies. Additionally, concerns regarding fetal exposure to ionising radiation are important considerations in maternal testing. This manuscript reviews the important physiological changes pertinent to the investigation of maternal cardiovascular disease in pregnancy.

BACKGROUND: Peripartum cardiomyopathy is associated with significant risks of decline in left ventricular function and adverse maternal and fetal outcome in subsequent pregnancy. The risks of pregnancy in women with dilated cardiomyopathy are unclear. We aimed to assess the outcome of pregnancy in women with dilated cardiomyopathy seen at our institution and to review the literature on this subject. METHODS: A retrospective audit of the outcomes of 14 pregnancies to 12 women with dilated cardiomyopathy. RESULTS: There were no cardiac events and no woman had a decline in left ventricular function during pregnancy. There was a high rate of prematurity and adverse fetal outcome related to this, including four neonatal deaths. CONCLUSION: Maternal outcomes in this small series were satisfactory though only three women had moderate-severe left ventricular dysfunction at baseline. There was a high rate of premature delivery and adverse neonatal outcome.

The practice of medicine depends on the accuracy of biochemical assays. The high prevalence of incidental masses on imaging necessitates a correct biochemical diagnosis before proceeding to radiological studies. Hormonal assays, tumour markers, and markers of cardiac injury are particularly susceptible to heterophile antibody interference which may lead to inaccurate and misleading results, inappropriate investigation and/or treatment, patient concern and potential harm. A case of heterophile antibody interference in the measurement of ACTH in a patient with Cushing's syndrome resulting in unnecessary invasive investigation is presented. Close collaboration and communication between laboratory and clinical staff is essential where laboratory results and the clinical picture are not congruent.

Melanoma is the most common cancer in women during their reproductive years and kills more young Australians than any other single cancer. Care of women whose pregnancy is complicated by a diagnosis of malignancy is complex. The risk of delaying treatment to the mother, the short-term and long-term risks of premature delivery to the child, and the immediate risks to the foetus and long-term risks to the child of maternal treatment with surgery, radiotherapy or medical therapies must be considered.

Sleep disordered breathing (SDB) which includes obstructive sleep apnoea (OSA) and upper airway resistance syndrome (UARS), has emerged as a risk factor for adverse maternal-foetal outcomes in pregnancy. Physiological changes of pregnancy predispose a woman 'at risk' towards developing SDB. The increasing incidence of OSA in pregnancy closely correlates with the population trends of obesity. Common screening tools validated in non-pregnant subjects including Epworth Sleepiness Scale (ESS) and Berlin Questionnaire (BQ) are poor predictors of SDB in pregnancy. Preeclampsia, gestational hypertension and gestational diabetes mellitus (GDM) are linked with SDB. Preeclampsia and OSA share common pathological associations. It is unclear if one predisposes the other. Foetal morbidity includes intrauterine growth restriction (IUGR), preterm delivery, low birth weight, neonatal intensive care unit (NICU) admission and Apgar score of less than seven at one minute. Continuous positive airway pressure (CPAP) is a well-documented treatment of SDB in pregnancy and has been shown to reverse some of the adverse events. It becomes imperative to diagnose and manage this condition as OSA causes substantial morbidity in the untreated pregnant patient and foetus. Three short clinical cases and a literature review on SDB on pregnancy are presented.

PURPOSE: This study aims to investigate the prevalence and factors predictive of vitamin D deficiency in patients with malignancy in Brisbane, Australia (latitude 27° S). METHODS: This is a prospective cross-sectional study measuring serum levels of 25-hydroxyvitamin D (25-OHD) in 100 subjects with non-haematological cancer at least 18 years of age not taking vitamin D supplements attending a day oncology unit and oncology/palliative care inpatient ward in Brisbane, Australia. RESULTS: Thirty-seven per cent of outpatient and 49 % of inpatient subjects respectively were vitamin D deficient. Functional status was predictive of low vitamin D levels. CONCLUSION: There was a high prevalence of vitamin D deficiency in patients with cancer in Brisbane, Australia.
