Vascular air embolism (VAE) is a known complication of contrast-enhanced CT (CECT) scan occurring in venous or arterial circulation with a wide spectrum of presentations. We report a case of a 44-year-old woman with endometrial adenocarcinoma stage IVB complicated with liver abscess and pulmonary embolism who developed VAE following a routine CECT scan after the sixth cycle of chemotherapy. This was an incidental finding and the patient remained asymptomatic throughout. As such, she was treated conservatively and gradually recovered. This case report serves as a reminder that VAE should be considered in patients presenting with unexplained symptoms following this procedure.

AIMS: Heart failure (HF) patients diagnosed with breast cancer (BC) may have a higher risk of death, and different HF presentation and treatment than patients without BC.

METHODS AND RESULTS: A total of 14 998 women with incident HF (iHF) or prevalent HF (pHF) enrolled in the Swedish HF Registry within and after 1 month since HF diagnosis, respectively, between 2008 and 2013. Patients were linked with the National Patient-, Cancer-, and Cause-of-Death Registry. Two hundred and ninety-four iHF and 338 pHF patients with BC were age-matched to 1470 iHF and 1690 pHF patients without BC. Comorbidity and treatment characteristics were compared using the χ2 tests for categories. Cox proportional hazard models assessed the hazard ratio (HR) and 95% confidence intervals (95% CIs) of all-cause and cardiovascular mortality among HF patients with and without BC. In the pHF group, BC patients had less often myocardial infarction (21.6% vs. 28.6%, P

Fulltext Molar pregnancy with normal viable fetus presenting with severe pre-eclampsia: a case report

Atuk FA, Basuni JBM

J Med Case Rep, 2018 May 21;12(1):140.

PMID: 29779493 DOI: 10.1186/s13256-018-1689-9

BACKGROUND: While gestational trophoblastic disease is not rare, hydatidiform mole with a coexistent live fetus is a very rare condition occurring in 0.005 to 0.01% of all pregnancies. As a result of the rarity of this condition, diagnosis, management, and monitoring will remain challenging especially in places with limited resources and expertise. The case we report is an interesting rare case which presented with well-described complications; only a few similar cases have been described to date.

CASE PRESENTATION: We report a case of a 21-year-old local Sarawakian woman with partial molar pregnancy who presented with severe pre-eclampsia in which the baby was morphologically normal, delivered prematurely, and there was a single large placenta showing molar changes.

CONCLUSION: Even though the incidence of this condition is very rare, recognizing and diagnosing it is very important for patient care and it should be considered and looked for in patients presenting with pre-eclampsia.

Longitudinal study on the impact of urinary continence and sexual function on health-related quality of life among Japanese men after robot-assisted radical prostatectomy

Ngoo KS, Honda M, Kimura Y, Yumioka T, Iwamoto H, Morizane S, et al.

Int J Med Robot, 2019 Aug;15(4):e2018.

PMID: 31115140 DOI: 10.1002/rcs.2018

BACKGROUND: The aim of this study is to investigate the impact of robotic-assisted radical prostatectomy (RARP) on the health-related quality of life (HRQOL).

METHODS: We prospectively reviewed HRQOL parameters using Short-Form Health Survey, patient self-reporting of urinary incontinence and International Index of Erectile Function, among patients who underwent RARP between 2010 and 2016.

RESULTS: Among 249 men studied, all had significantly worse HRQOL domain scores at 1 month post operatively but 24 months after surgery, all domains reached or surpassed their baseline values. Only Bodily Pain, General Health, Role-Emotional, Mental Health domains, and Mental Health Composite were significantly improved. Improvement in urinary continence was mirrored by improvements in both Mental and Physical Component Scores.

CONCLUSIONS: Within a 2-year post-operative period, men who underwent RARP had regained their overall quality of life. The recovery of urinary continence significantly impacted the mental, physical, emotional, and social well-being of those patients.

Fulltext Acoustic neuroma with orofacial paresthesia: description of an atypical presentation

Lim CC, Misron K, Liew YT, Wong EHC

BMJ Case Rep, 2019 Nov 04;12(11).

PMID: 31690691 DOI: 10.1136/bcr-2019-232275

Acoustic neuroma (AN) usually manifests with asymmetric hearing loss, tinnitus, dizziness and sense of disequilibrium. About 10% of patients complain of atypical symptoms, which include facial numbness or pain and sudden onset of hearing loss. Patients with atypical symptoms also tend to have larger tumours due to the delay in investigation. We report a particularly interesting case of a patient presented to us with numbness over her right hemifacial region after a dental procedure without significant acoustic and vestibular symptoms. Physical examination and pure tone audiometry revealed no significant findings but further imaging revealed a cerebellopontine angle mass. The changing trends with easier access to further imaging indicate that the presentation of patients with AN are also changing. Atypical symptoms which are persistent should raise clinical suspicion of this pathology among clinicians.

Metformin: A Salutary Candidate for Colorectal Cancer Treatment in Patients with Diabetes

Samuel VP, Dahiya R, Singh Y, Gupta G, Sah SK, Gubbiyappa SK, et al.

J Environ Pathol Toxicol Oncol, 2019;38(2):133-141.

PMID: 31679276 DOI: 10.1615/JEnvironPatholToxicolOncol.2019029388

The current study is a review of the literature on patients with diabetes who are diagnosed with colorectal cancer (CRC), encompassing recent research on CRC and the molecular level changes occurring in these patients on the basis of varying environmental as well as non-environmental factors. It has been noted that nearly 50% of all patients undergo the systemic treatment module; however, most of them exhibit drug resistance. In addition, targeted gene therapy has also been used in treatment but has been found to be effective only in patients with a specified molecular profile (or else this might lead to an increased risk of developing resistant mutations). This has led to increasing interest among researchers in finding innovative treatment options. Metformin, a biguanide, has been widely used in treating diabetes. The drug has been reportedly used in cases of hypothesis-generating retrospective population studies of diabetic patients showing reduced incidence of cancer. Metformin helps in reduction of excess insulin levels that possess various effects on cell signaling and metabolism. Nonetheless, there is need for an in-depth study on its molecular mechanism to fill any existing research gaps.

Diabetes mellitus (DM) is frequently increased in many countries and become a serious health problem worldwide. Diabetes is associated with dysfunction of different organs such as heart, eyes, blood vessels, nerves, and kidneys. There is a strong connection between diabetes and cancer. Metformin is one of the most commonly prescribed oral antidiabetic medicines and it is suggested as the first-line therapy due to its comparatively safe, inexpensive, effective and well-tolerated. Some of the in vitro and in vivo investigations proved that metformin may have a direct anticancer action by preventing the proliferation of malignant cells and formations of the colony, inducing arrest of cell cycle and apoptosis and suppressing tumor growth. The antiproliferative mechanism of metformin alone or in combination with various chemotherapeutic agents is complex and involves several beneficial roles. In this regard, clinical studies are required to explain these roles. In the coming future, the use of metformin, alone or in combination with current chemotherapy, might be a conventional approach to effectually manage lung cancer. This mini-review provides a critical overview of currently available clinical trials investigating the effects of metformin in lung cancer.

Fulltext Diffuse large B-cell lymphoma presenting with extensive cutaneous infiltration

Shamsudin N, Chang CC

Singapore Med J, 2012 Sep;53(9):e198-200.

PMID: 23023915

We report a case of systemic diffuse large B-cell lymphoma presenting with extensive infiltration of the skin. A 56-year-old woman presented with a two-month history of pruritic erythematous plaques and nodules over the neck, trunk and upper limbs. She also had night sweats, weight loss, lethargy and reduced effort tolerance. Systemic examination revealed a pale, ill appearance with hepatosplenomegaly and lymphadenopathy. Blood investigations showed pancytopenia (haemoglobin 6.3 g/dL, total white cell count 3.0 × 10(9)/L, platelet count 138 × 10(9)/L) with a few suspicious mononuclear cells and a mildly elevated lactate dehydrogenase level (478 U/L). Skin biopsy demonstrated diffuse sheets and nodular infiltrates of CD20 and CD79a positive neoplastic cells in the dermis and subcutis. Computed tomography revealed multiple cervical, axillary, mediastinal, para-aortic and mesenteric lymph nodes. Bone marrow aspiration and trephine biopsy confirmed marrow involvement by non-Hodgkin's lymphoma. The patient was treated with chemotherapy, which resulted in resolution of the skin lesions.

Fulltext Leucocoria in a boy with Kawasaki disease: a diagnostic challenge

Che Mahiran CD, Alagaratnam J, Liza-Sharmini AT

Singapore Med J, 2009 Jul;50(7):e232-4.

PMID: 19644606

Retinoblastoma, the most common primary intraocular malignancy of childhood, usually presents in the first three years of life. Atypical presentation of retinoblastoma can masquerade as virtually any ocular or orbital pathology, which may lead to diagnostic dilemmas especially in the presence of other systemic diseases. We report a 20-month-old boy who was diagnosed with coronary aneurysm as a complication of Kawasaki disease, and presented with sudden left eye redness. His mother noticed the presence of white pupillary reflex three months earlier. Atypical acute ocular presentation secondary to Kawasaki disease was initially suspected, but the presence of multiple calcification and mild proptosis on imaging suggested characteristics of advanced retinoblastoma. Histopathological examination of the enucleated eye, which revealed a classical rosette pattern appearance, confirmed the diagnosis. Atypical presentations of retinoblastoma are usually associated with advanced disease. The presence of other systemic conditions further complicates the diagnosis. Early diagnosis is important to reduce the mortality and morbidity.

Fulltext Anaemia and cancer treatment: a conceptual change

Khan FA, Shukla AN, Joshi SC

Singapore Med J, 2008 Oct;49(10):759-64.

PMID: 18946607

Anaemia is the most common haematological abnormality in cancer patients, and unfortunately, it is often under-recognised and undertreated. The aetiopathology of anaemia in cancer patients is complex and is usually multifactorial. There is enough evidence suggesting that tumour hypoxia in anaemic patients has a negative impact on the treatment outcomes in cancer patients. The use of recombinant human erythropoietin is becoming a new standard of care in cancer patients. Various well-controlled studies have shown that the use of erythropoietin (EPO) increases the haemoglobin level, thereby decreasing the need for frequent transfusions and improving the tumour responses, cancer-free survival and quality-of-life parameters in cancer patients. However, a few recent clinical trials failed to replicate the survival benefit. Hence, a free unrestricted use of EPO is to be avoided. The past belief that anaemia does not matter in cancer patients is now considered invalid and is being seriously challenged. This article aims to present some recent findings on the impact of anaemia on outcomes, with discussion on the possible causes and effects. The benefits of the use of EPO analogues in cancer-related anaemia are also presented.

Cervical cancer burden, status of implementation and challenges of cervical cancer screening in Association of Southeast Asian Nations (ASEAN) countries

Zhao S, Huang L, Basu P, Domingo EJ, Supakarapongkul W, Ling WY, et al.

Cancer Lett, 2022 Jan 28;525:22-32.

PMID: 34728309 DOI: 10.1016/j.canlet.2021.10.036

Multiple barriers impede the transformation of evidence-based research into implementation of cervical cancer screening in ASEAN countries. This review is the first of its kind to show the disease burden of cervical cancer, progress till date to implement screening and corresponding challenges, and propose tailored solutions to promote cervical cancer prevention in ASEAN. In 2020, approximately 69 000 cervical cancer cases and 38 000 deaths happened in ASEAN, and more than 44% and 63% increases on new cases and deaths are expected in 2040. Only four countries have initiated population-based cervical cancer screening programs, but the participation rate is less than 50% in some countries and even lower than 10% in Myanmar and Indonesia. Inequity and unavailability in service delivery, lack of knowledge and awareness, limited follow-up and treatment capacity, and funding sustainability affect successful scale-up of cervical cancer screening most in ASEAN. Implementing HPV detection-based primary screening, appropriate management of screen-positives, enhancing health education, integrating health services can accelerate reduction of cervical cancer burden in ASEAN. Achieving high screening coverage and high treatment compliance will help ASEAN countries remain aligned to cervical cancer elimination strategies.

18F-PSMA-1007 PET/CT for Initial Staging of Renal Cell Carcinoma in an End-Stage Renal Disease Patient

Marafi F, Sasikumar A, Aldaas M, Esmail A

Clin Nucl Med, 2021 Jan;46(1):e65-e67.

PMID: 33181733 DOI: 10.1097/RLU.0000000000003354

A 46-year-old man with end-stage renal disease and renal cell carcinoma underwent F-FDG PET/CT for initial staging followed by F-PSMA-1007 PET/CT. Unlike F-FDG, which undergoes renal clearance, F-PSMA-1007 undergoes hepatobiliary clearance and thus generates superior quality images. F-PSMA-1007 PET/CT showed intense tracer-avid left renal mass lesion (FDG nonavid); lytic bone lesions (FDG avid) and single liver lesion (FDG nonavid). This case highlights the superiority of F-PSMA-1007 over F-FDG PET/CT in identifying primary lesion as well as metastatic sites in case of renal cell carcinoma even in the presence of end-stage renal disease.

PMID: 9663321

A case of gigantic pyogenic granuloma with three recurrences in the lower anterior gingiva is presented. Surgical wide excision of the lesion is the treatment of choice. The tumour must be excised down to the periosteum and the irritants around it removed to avoid recurrence. A contributing factor to the gigantic lesion is hormonal changes during pregnancy. Long-term review for 18 months after the third surgery showed no evidence of recurrence at the surgical site.

PMID: 11242630

INTRODUCTION: Although the majority of patients with primary hyperparathyroidism have a relatively asymptomatic benign disorder, there are patients who have a more aggressive disorder.

CLINICAL PICTURE: We report a case of primary hyperparathyroidism presenting during pregnancy complicated by antepartum haemorrhage and severe prematurity. The diagnosis was made postpartum, when her problems rapidly progressed to result in severe neuromuscular weakness, bilateral pathological hip fractures as well as nephrolithiasis.

TREATMENT: Surgical parathyroidectomy was performed. The underlying lesion was a large solitary parathyroid adenoma with cystic elements.

CONCLUSION: Primary hyperparathyroidism is not an innocuous disease and can result in severe morbidity if left untreated.
