ABSTRACT
A pregnant woman in her 20s presented with an excessive desire to smell a specific household cleaning product. She was found to have severe iron deficiency anaemia and her symptoms resolved following intravenous iron supplementation. She described symptoms of fatigue, shortness of breath and olfactory cravings. The specific scent could not be replicated with other smells and the woman had to significantly modify her lifestyle to accommodate the excessive desire. She had a similar experience during her prior pregnancy which resolved after the correction of severe iron deficiency anaemia. This unique symptom has been described as desiderosmia: iron deficiency manifesting as olfactory cravings. This underappreciated but useful symptom is defined as a separate entity to pica, as there is an absence of desire to ingest the product. Desiderosmia can harm mother and baby through inhalation of potentially harmful fumes; hence, women who describe this symptom should be assessed for iron deficiency anaemia.

BACKGROUND: The current COVID-19 pandemic has been shown to have profound effects on pregnant women globally, particularly, on their psycho-social wellbeing. Despite this, there has been limited qualitative inquiry into the experiences of pregnant women during the pandemic. AIM: This original research aimed to study the perspectives of pregnant women in Australia in relation to the impact of the COVID-19 pandemic on their pregnancy experience. METHODS: A qualitative descriptive study design with semi-structured interviews was adopted. The study was performed in Melbourne, Australia. A total of fifteen interviews were conducted. Data was analysed thematically to develop major themes and subthemes. RESULTS: A total of four major themes were developed: support for a positive experience, impact on preparedness in pregnancy and beyond, facing uncertainty of a pandemic, and retaining resilience and optimism. CONCLUSIONS: The COVID-19 pandemic has affected the experience of pregnant women with potential to compromise their psycho-social wellbeing. The major themes identified in this study offer insight to organisations to develop woman-centred care during the pandemic and optimise the psycho-social wellbeing of pregnant women.

BACKGROUND: Heterotopic pregnancies are increasing in prevalence and this case highlights the importance of excluding the diagnosis in patients with pelvic pain following miscarriage. A known pre-existing intrauterine pregnancy can be falsely reassuring and delay the diagnosis of a potentially life-threatening concurrent ectopic pregnancy. CASE PRESENTATION: In this report, we describe a case of spontaneous heterotopic pregnancy in a woman who had initially presented with pelvic pain and vaginal bleeding, and was diagnosed on pelvic ultrasound with a missed miscarriage; a non-viable intrauterine pregnancy. She re-presented 7 days later with worsening pelvic pain and bleeding, and a repeat pelvic ultrasound identified a ruptured tubal ectopic pregnancy in addition to an incomplete miscarriage of the previously identified intrauterine pregnancy. She underwent an emergency laparoscopy where a ruptured tubal ectopic pregnancy was confirmed. CONCLUSION: Being a time critical diagnosis with the potential for an adverse outcome, it is important that the emergency physician considers heterotopic pregnancy as a differential diagnosis in patients presenting with pelvic pain following a recent miscarriage. The same principle should apply to pelvic pain in the context of a known viable intrauterine pregnancy or recent termination of pregnancy. A combination of clinical assessment, beta human chorionic gonadotropin levels, point of care ultrasound and formal transvaginal ultrasound must be utilized together in these situations to explicitly exclude heterotopic pregnancy.

Ovarian ectopic pregnancies are a rare occurrence; however the incidence is on the rise. Preoperative diagnosis remains difficult due to nonspecific clinical symptoms and USS findings. Most patients undergo diagnostic laparoscopy with subsequent surgical management. We present the case of a 32-year-old female who presented with vaginal bleeding and an unsited pregnancy, with a BhCG of 24693. Formal USS described unruptured right tubal ectopic with ovarian pregnancy being diagnosed at laparoscopy. A wedge resection was conducted to preserve ovarian function. Postoperative recovery was uneventful and BhCG levels returned to zero (nonpregnant) in an outpatient setting. Although laparoscopy remains the gold standard of diagnosis and treatment, in this case report we discuss benefits of early diagnosis for fertility conserving management, including nonsurgical options.
ABSTRACT
There is limited evidence supporting the routine use of Holter monitoring (HM) in patients with acute ischaemic stroke. This study aimed to assess the diagnostic yield of HM and determine whether any cardiac disease parameter(s) would permit more focused targeting of HM. We performed a retrospective evaluation of HM in patients with acute ischaemic stroke admitted to our hospital over a one-year period to assess diagnostic yield and whether certain cardiac disease parameters were correlated with HM results. The diagnostic yield was 9%, the number needed to screen was 11, and the cost to detect one clinically significant case was AUS$1,300. Apart from age, stratifying patients by cardiac disease parameters did not predict HM result. This strengthens the use of HM in all patients presenting with acute ischaemic stroke of unknown aetiology.

The skin secretions of Australian tree frogs are rich in peptides with potential antimicrobial activity. They interrupt bacterial cell membranes, although precisely how and whether all peptides have the same mechanism is not known. The interactions of three of these peptides-aurein 1.2, maculatin 1.1, and caerin 1.1 with supported phospholipid bilayers-are examined here using quartz crystal microbalance and atomic force microscopy. These approaches enabled us to reveal variations in material structure and density as a function of distance from the sensor surface when comparing mass sensorgrams over a range of harmonics of the natural resonance of the sensor crystal and hence obtain for the first time to our knowledge a mechanistic assessment of membrane disruption. We found that caerin inserted into the bilayer in a transmembrane manner, regardless of concentration and phospholipid composition consistent with a pore-forming mechanism. In contrast, maculatin and aurein interacted with membranes in a concentration-dependent manner. At low concentrations (<5 microM), maculatin exhibited transmembrane incorporation whereas aurein was limited to surface association. Upon reaching a threshold value of concentration, both peptides lysed the membrane. In the case of maculatin, the lysis progressed in a slow, concentration-dependent manner, forming mixed micelles, as shown by atomic force microscopy imaging. Aurein-induced lysis proceeded to a sudden disruption, which is consistent with the "carpet" mechanism. Both maculatin and aurein exhibit specificity toward phospholipids and thus have potential as candidates as antimicrobial drugs.
