Background: Point-of-care bedside lung ultrasound is a diagnostic adjunct in the management of respiratory diseases. We describe the clinical progress and lung ultrasound findings of a Singaporean COVID-19 intensive care unit patient who was diagnosed with COVID-19 infection. Methods: The clinical course of one COVID-19 patient managed in the intensive care unit was traced. The patient was diagnosed with COVID-19 virus infection and intubated after developing respiratory failure. Serial point-of-care bedside lung ultrasound was performed by the managing intensivist daily, and correlated with the clinical progress and chest X-ray imaging done for the patient. Results: The patient exhibited lung ultrasound findings consistent with that described for viral pneumonias. This included numerous B-lines and subpleural consolidations with disrupted pleural lines distributed symmetrically, predominantly in bilateral upper BLUE points, and lower BLUE points bilaterally. Coalescing B-lines leading on to the development of bilateral “white lung” were associated with worsening acute respiratory distress syndrome. An increased density or reduction of the B-lines was associated with clinical improvement or deterioration, respectively. Conclusions: Trained clinicians, who are familiar with point-of-care lung ultrasonography, may consider point-of-care bedside ultrasound as an important adjunct to history and physical examination for the diagnosis and management of COVID-19 when advanced imaging is not available because of logistical reasons or infectious control. This applies in particular to cases where resources are limited, and patient transfers to facilities offering such services may prove hazardous.

Objectives: This case series would like to highlight hypophosphatemia related to ferric carboxymaltose and its adverse clinical consequences. Background: Intravenous iron supplementation is a good alternative to oral iron replacement in iron deficiency anaemia due to its ability to correct iron deficit with minimal infusions without incurring the gastrointestinal side effects of oral iron replacement. Ferric carboxymaltose is one common formula for intravenous iron supplementation. However, an increasingly recognised adverse side‐effect of intravenous ferric carboxymaltose is hypophosphatemia. There has been increasing reports and studies highlighting hypophosphatemia related to intra‐venous iron therapy. Though initially thought to be transient and asymptomatic, recent studies have shown that persistent hypophosphatemia in iron therapy can result in debilitating disease including myopathy, fractures and osteomalacia. Methods: A retrospective analysis of all patients who had ferric carboxymaltose was performed. Results: We highlight 3 cases where hyposphatemia affected the clinical outcomes. Conclusion: With the increased use of IV iron it is important to be aware of the high potential for hypophosphatemia secondary to ferric carboxymaltose. [ABSTRACT FROM AUTHOR]

Point-of-care ultrasound is increasingly important in the management of acute medical emergencies. An elderly man was brought to the emergency department after 2 days of fever and urinary retention. He was drowsy and had peri-arrest arrhythmia. He was hypoperfused peripherally with a systolic blood pressure of 45 mmHg and so was managed as for septic shock with no obvious aetiology. Chest and abdominal physical examinations were unremarkable. The source of sepsis was unclear. A point-of-care abdominal ultrasound was performed by the reviewing internist which detected a pneumoperitoneum, leading to a change in diagnosis to a perforated viscus which was confirmed later by a CT of the abdomen and pelvis.

Summary: Ferric carboxymaltose (FCM) administration helps reduce transfusion requirements in the perioperative situation, which improves patient outcomes and reduces healthcare costs. However, there is increasing evidence of hypophosphataemia after FCM use. We aim to determine the incidence of hypophosphataemia after FCM administration and elucidate potential biochemical factors associated with the development of subsequent hypophosphataemia. A retrospective review of anonymised data of all FCM administrations in a single institution was conducted from August 2018 to August 2021. Each unique FCM dose administered was examined to assess its effect on Hb and serum phosphate levels within the subsequent 28 days from each FCM administration. Phosphate levels were repeatedly measured within the 28‐day interval and the lowest phosphate level within that period was determined. Patients' serum phosphate levels within 28 days of FCM administration were compared against normal serum phosphate levels within 2 weeks before FCM administration. The odds ratios of various pre‐FCM serum markers were calculated to elucidate potential biochemical predictors of post‐FCM hypophosphataemia. In 3 years, a total of 1296 doses of FCM were administered to 1069 patients. The mean improvement in Hb was 2.45 g/dL (SD = 1.94) within 28 days of FCM administration, with the mean time taken to peak Hb levels being 6.3 days (SD = 8.63), which is earlier than expected, but was observed in this study and hence reported. The incidence of hypophosphataemia <0.8 mmol/L was 22.7% (n = 186), and <0.4 mmol/L was 1.6% (n = 9). This figure is lower than the numbers reported in previously published meta‐analyses given that routine checks of serum phosphate levels were not conducted initially and hence could possibly be higher. The odds of developing hypophosphataemia (<0.8 mmol/L) were 27.7 (CI: 17.3–44.2, p < 0.0001) if baseline serum phosphate was less than 1 mmol/L. The odds of developing hypophosphataemia (<0.8 mmol/L) were 1.3 (CI: 1.08–1.59, p < 0.01) if the change in Hb levels observed after FCM administration were more than 4 g/dL. Hypophosphataemia after FCM administration is significant and FCM should be used by clinicians with caution. [ABSTRACT FROM AUTHOR]

Background: Arterial and venous thrombosis are reported to be common in critically ill COVID-19 patients. Method and results: This is a national multicenter retrospective observational study involving all consecutive adult COVID-19 patients who required intensive care units (ICU) admission between 23 January 2020 and 30 April 2020 in Singapore. One hundred eleven patients were included and the venous and arterial thrombotic rates in ICU were 1.8% (n = 2) and 9.9% (n = 11), respectively. Major bleeding rate was 14.8% (n = 16). Conclusions: Critically ill COVID-19 patients in Singapore have lower venous thromboembolism but higher arterial thrombosis rates and bleeding manifestations than other reported cohorts.

The article discusses sigmoid colon adenocarcinoma, who underwent anterior resection and adjuvant chemotherapy seven months earlier, was found to have a hypermetabolic. Topics include The lesion was not palpable and was also occult on both mammogram and ultrasound imaging; nodular adenosis is a common benign breast lesion which can appear as a nodular mass on imaging; and the patient remains well three years on with no clinical or radiologic evidence of primary metastatic disease.

Introduction: This study aimed to evaluate the clinical utility of positron emission tomography/magnetic resonance imaging (PET/MRI), especially in comparison with PET/computed tomography (CT), which has been widely used in clinical practice in multiple myeloma., Method: F-18 fluorodeoxyglucose PET/MRI and PET/ CT studies were done at baseline and when at least a partial response to treatment was achieved. These were done for newly-diagnosed myeloma patients who have not had more than 1 cycle of anti-myeloma treatment, or for relapsed and/or refractory myeloma patients before the start of next line of therapy., Results: PET/MRI correlated significantly with PET/CT, in terms of number of lesions detected, standardised uptake value (SUVmean and SUVmax, both at baseline and post-treatment. PET/MRI and PET/CT correlated with survival at baseline, but not post-treatment., Conclusion: In this study, PET/MRI was more sensitive in detecting early disease and disease resolution post-treatment, compared with PET/CT. However, PET/MRI was less sensitive in detecting lesions in the ribs, clavicle and skull., Competing Interests: No relevant conflicts of interest to disclose.

OBJECTIVE. The purpose of this study is to provide a concise summary of the current experience with 68 Ga-labeled prostate-specific membrane antigen (PSMA)-11 imaging of prostate and nonprostate malignancies and benign conditions. CONCLUSION. PSMA is overexpressed in prostate cancer and in the neovasculature of many other malignancies. The relevance of PSMA as a biologic target, coupled with advances in the design, synthesis, and evaluation of PSMA-based radionuclides for imaging and therapy, is anticipated to play a major role in patient care.
