Today's global health challenges in underserved communities include the growing burden of cancer and other non-communicable diseases (NCDs); infectious diseases (IDs) with epidemic and pandemic potential such as COVID-19; and health effects from catastrophic 'all hazards' disasters including natural, industrial or terrorist incidents. Healthcare disparities in low-income and middle-income countries and in some rural areas in developed countries make it a challenge to mitigate these health, socioeconomic and political consequences on our globalised society. As with IDs, cancer requires rapid intervention and its effective medical management and prevention encompasses the other major NCDs. Furthermore, the technology and clinical capability for cancer care enables management of NCDs and IDs. Global health initiatives that call for action to address IDs and cancer often focus on each problem separately, or consider cancer care only a downstream investment to primary care, missing opportunities to leverage investments that could support broader capacity-building. From our experience in health disparities, disaster preparedness, government policy and healthcare systems we have initiated an approach we call flex-competence which emphasises a systems approach from the outset of program building that integrates investment among IDs, cancer, NCDs and disaster preparedness to improve overall healthcare for the local community. This approach builds on trusted partnerships, multi-level strategies and a healthcare infrastructure providing surge capacities to more rapidly respond to and manage a wide range of changing public health threats.A 60-year-old man with no significant medical history was found unresponsive by his neighbour; he had neck stiffness on physical examination in the emergency department. He later developed acute hypoxic respiratory failure requiring endotracheal intubation. He is a binge drinker on weekends, and methamphetamine was detected in his urine. Contrast-enhanced CT of the chest, abdomen and pelvis revealed multifocal pneumonia, bilateral psoas abscesses and right infraspinatus muscle abscess. Blood, sputum and cerebrospinal fluid cultures grew Streptococcus pneumoniae Transthoracic echocardiography (TTE) revealed tricuspid endocarditis with mild valve insufficiency. He was initially treated with intravenous antibiotics and underwent incision and drainage of right psoas abscess. However, he still had recurrent fever and confusion. Repeat TTE showed larger vegetation, and he also developed septic emboli at the posterior basal right lower lobe pulmonary artery. The patient underwent tricuspid valve debridement and was finally discharged after completing 6 weeks of intravenous antibiotic treatment.Compromised free flap perfusion secondary to thrombus formation is a routinely encountered complication in microvascular free tissue transfer. Various modalities were tried out prophylactically to prevent thrombus formation, and likewise, various methods are tried for salvaging the flap with effective thrombectomy. We present the use of Fogarty vascular catheter for thrombectomy and effective salvage of the flap.Endobronchial ultrasound (EBUS) has long been a common diagnostic tool used in the diagnosis of pulmonary pathologies. In the last decade, increased interest has been shown in its usage via the oesophagus for sampling lesions inaccessible via the airways. We describe three cases in which we used this modality to biopsy lesions not visualised via conventional EBUS and which would be too risky to be attempted via a CT-guided biopsy with a high likelihood of complications. find more More focused education on using EBUS via the oesophagus for respiratory trainees could greatly improve overall clinical practice. It improves the diagnostic yield of lesions and prevents subsequent referral to gastrointestinal colleagues which may delay diagnosis especially during the COVID-19 pandemic as was the case in our patient cohort where services are already limited. EBUS, due to its smaller size, is less irritant to the upper airways and requires less sedation than endoscopic ultrasound (EUS) scopes. It is also shorter than an EUS scope improving manoeuvrability. Each of our cases resulted in early histological diagnosis and subsequent appropriate treatment.A 61-year-old Hispanic man with no psychiatric history presented with an acute onset of personality changes, including aggression and hypersexuality, which progressed to hallucinations and fluctuations in mental status, and was diagnosed with anti-N-methyl-D-aspartate receptor encephalitis. This report emphasises the importance of having anti-NDMA receptor encephalitis on the list of differential diagnoses in acute, unprovoked personality changes in older adults.Toxic leukoencephalopathy (TL) is characterised by an insult to the myelin of the cerebral white manner which can be attributed to a number of offending agents, including drugs of abuse. We report a case of a fit and well young man presenting to hospital with an altered mental state. It was subsequently determined that the patient inhaled a significant volume of nitrous oxide recreationally. Nitrous oxide is easily accessible and the second most consumed drug among young adolescents (16-24 years old). Following extensive investigations and brain imaging, the patient was subsequently diagnosed with TL. After a prolonged hospital admission, he went on to make a complete neurological recovery.We report here the case of a 40-year-old man who presented with sphenoid sinusitis complicated by jugular and cerebral venous thrombosis and intracranial infection 6 weeks after coiling of an anterior choroidal artery aneurysm. The pathogeny of this unusual and severe complication is discussed.Marchiafava-Bignami disease (MBD) is a rare, toxic demyelinating disorder of the central nervous system associated with chronic alcoholism and malnutrition. The clinical presentation is varied and non-specific, including symptoms of acute dementia, impaired consciousness, dysarthria, hemiparesis, pyramidal tract signs, seizure activity, ataxia and signs of interhemispheric disconnection. The differential diagnosis of MBD may include Wernicke's encephalopathy, multiple sclerosis, encephalitis, infectious or paraneoplastic leucoencephalopathy, infarction, Alzheimer's disease, multi-infarct dementia and frontotemporal lobar degeneration (Pick) disease. The diagnosis of MBD is dependent on MRI findings of hyperintensity of the corpus callosum on T2 and fluid-attenuated inversion recovery T2 sequences, with or without extracallosal lesions. The use of MRI in diagnosis has allowed for early initiation of treatment with parenteral thiamine, and improved the prognosis of MBD from frequently fatal to a mortality of less than 8%.
