Chest pain is the second most common presenting symptom to emergency departments (ED) in Australia, although up to 85% of these patients do not have an acute coronary syndrome (ACS). Cardiologist-led rapid access chest pain clinics (RACPC) have been proposed overseas to assist in the management of such patients, with prompt outpatient assessment if patients are deemed low risk and discharged from the ED. The use of RACPCs in Australia has been only recently proposed; we therefore sought to examine one such RACPC in an Australian context...

Background: Imaging studies, particularly simple and contrast-enhanced tomography, constitute the first diagnostic approach to detect recurrence of musculoskeletal tumors. The aim of the present retrospective study was to demonstrate the usefulness of scintigraphy plus SPECT/CT (single photon emission computed tomography) with thallium-201 (201 Tl) in the evaluation of malignant musculoskeletal tumors with suspicion of recurrence or metastatic disease. Methods: Eight weeks after the last therapy, 72 scintigraphy and SPECT/CT studies were performed to assess regional recurrence and metastatic disease in 42 patients with different types of malignant musculoskeletal tumors, such as osteosarcoma, Ewing's sarcoma, rhabdomyosarcoma, retinoblastoma, synovial sarcoma, and Wilms tumor at the Hospital Infantil de México Federico Gómez...

Previous animal studies have not conclusively determined the association between exposure to humidifier disinfectants (HDs) containing 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) and/or 2-methyl-4-isothiazolin-3-one (MIT) and development of HD-associated lung injuries. Nonetheless, patients exposed to HDs containing only CMIT and/or MIT showed clinically similar lung injuries to those exposed to HDs containing polyhexamethylene guanidine (PHMG) or oligo (2-[2-ethoxy]ethoxyethyl) guanidinium chloride (PGH)...

Primary bronchus-associated lymphoid tissue (BALT) lymphoma comprises 5% of non-Hodgkin's lymphoma (NHL) and usually has an indolent course. Synchronous primary lung cancers with BALT lymphoma are seldom seen in patients with adenocarcinoma of the lung. Synchronous squamous cell carcinoma (SCC) and BALT lymphoma is an extremely rare occurrence. We report an unusual case of stage 4 BALT lymphoma requiring treatment that revealed an underlying ipsilateral mass causing a diagnostic dilemma. An 84-year-old female with a history of systemic lupus erythematosus, deep vein thrombosis, and thrombotic microangiopathy presented to the hospital with cough and dyspnea on exertion...

A 93-year-old woman was admitted to the hospital because of respiratorydiscomfort. A chest CT scan indicated aspiration pneumonitis and, simultaneously, intussusception was observed in the splenic flexure region. Abdominal enhance CT scan revealed a tumor in the advanced region of intussusception. Laparoscopy-assisted ileocecal resection was performed. Since the intussusception was difficult to reduce laparoscopically, the ileocecum was mobilized and the intussusception was reduced manually. In the resected specimen, a type 1 tumor was observed in the cecum and histopathologic ally diagnosed as cercal cancer...

The diagnosis of pneumonia is challenging. Our objective was to assess whether a low-dose computed tomography (LDCT) modified the probability of diagnosing pneumonia in elderly patients.We prospectively included patients aged over 65 years, with a suspicion of pneumonia treated with antimicrobial therapy. All patients had a chest radiograph and LDCT within 72 h of inclusion. The treating clinician assessed the probability of pneumonia before and after the LDCT by using a Likert scale. An adjudication committee retrospectively rated the probability of pneumonia and was considered as reference for diagnosis...

INTRODUCTION: Pulmonary intravascular talcosis is a rare condition occurring in intravenous drug users injecting oral medications. Talc results in a foreign-body granulomatous reaction giving a radiological haematogenic miliary appearance mimicking miliary tuberculosis. Drug users represent a population at risk for both these conditions and their distinction may be challenging. CASE REPORT: We reported the case of a man, 33 year-old, intravenous drug addict, detected by the health services because he was the partner of a person who died of contagious and multi-resistant tuberculosis...

Diffuse idiopathic skeletal hyperostosis (DISH) is an increasingly prevalent ankylosing condition. Patients with DISH have an increased risk of spinal fractures, hypothetically the result of biomechanical changes in the spine. The aim of this study was to analyze the occurrence of biomechanical stress shielding in patients with DISH. To do this, bone mineral density (BMD) was measured longitudinally in the vertebral bodies of subjects with and without DISH and in the newly formed bone of subjects with DISH...

We present a 64-year-old woman with autosomal dominant polycystic kidney disease and hepatic cysts admitted to our hospital for high fever, intense coughing and right abdominal pain. The chest X-ray showed right pleural effusion suggestive of pneumonia. An abdominal ultrasound and computed tomography (CT) were done but did not show evidence of cyst infection or other abdominal complications. A gallium-67-citrate single-photon emission CT/CT, a relatively cheaper technique than positron emission tomography/CT was performed...

Empyema secondary to foreign body aspiration is rare in adults. We present a case of empyema in a 77-year-old male patient related to a remote aspiration event during a dental procedure. A CT of the chest and bronchoscopy confirmed that a metallic foreign body was located within the right lower lobe bronchus. His pleural fluid culture revealed Sphingomonas paucimobilis which is a low-virulent opportunistic gram-negative bacilli and rarely causes infection. The patient received meropenem followed by levofloxacin and recovered uneventfully...

Tuberculosis continues to be a major health problem worldwide. Multidrug resistant tuberculosis (MDR-TB) infection that occurs in childhood is caused by adult MDR-TB agents which are in circulation and resistant to primary drugs. In this case report a 17-month-old child with MDR-TB who was cured after a 24-month therapy regimen was presented. Physical examination of a 17-month-old girl admitted to the hospital with the cause of recurrent pneumonia revealed a rubbery lymphadenopathy less than 2 cm in the right upper cervical region...

Routine imaging for mediastinal malignancies includes chest X-ray, CT or MRI. T1 and T2 mapping are novel MRI techniques which may have a role in expanding the assessment of internal tumour characteristics. This case report details two middle-aged women who had similar clinical presentations of mediastinal masses of comparable size and appearance when assessed with routine imaging. T1 and T2 maps were acquired on MRI to investigate whether these tumours could be further differentiated prior to surgery. T1 and T2 mapping supported suspicion for which tumour components were solid and cystic, as subsequently confirmed histologically...

REVIEW

Sarcoidosis is a multisystem granulomatosis which may result in a wide variety of clinical and biological presentations. Symptoms are often nonspecific, and incidental abnormal findings on chest radiography is rather common. Although sarcoidosis resolves favorably in most cases, some localizations can provoke functional impairment or even impact on patients' prognosis. The diagnosis is based on a pathological hallmark which is the non-necrotizing epithelioid-cell rich granuloma. Owing to the ability to detect inflammation throughout the body with a high sensibility, FDG-PET/CT gained a central role in sarcoidosis because it can suggest the diagnosis in certain clinical context, guide biopsy, evaluate the extent of the disease, help assess the prognosis, and monitor immunosuppressive therapy...

Sarcoidosis is a granulomatous disease of unknown cause, occurs worldwide and has a highly variable prevalence. The disease is typically dominant in the lungs, although it can affect virtually any organ and is unpredictable in its clinical course. The severity of pulmonary sarcoidosis ranges from incidentally discovered radiographic abnormalities in asymptomatic patients to a chronic progressive disease that is refractory to treatment. Mortality from sarcoidosis appears to have increased in the past three decades, with respiratory failure being the most common cause of sarcoidosis-related death...
