RESUMO
Introduction: Aortic pseudoaneurysms are a type of contained rupture where most of the aortic wall is breached, leaving only a thin rim of the remaining wall or adventitia to hold the blood. This condition carries a high risk of rupture and potentially fatal complications. Typically, patients present with chest pain; haemoptysis can also occur, though rarely. Case description: A 64-year-old male who presented with two episodes of haemoptysis, with no history of cardiovascular surgery or trauma. A chest computerized tomography (CT) followed by an aortogram revealed a thoracic aortic pseudoaneurysm and the patient underwent surgical aortic repair without any complications. This case underscores the rare presentation of thoracic aortic pseudoaneurysm. Discussion: Haemoptysis is a rare manifestation of thoracic aorta pseudoaneurysm and can be a warning sign of impending rupture. Haemoptysis may occur due to formation of aortopulmonary fistula or direct erosion of pseudoaneurysm into lung parenchyma. Conclusion: It is imperative for clinicians to recognise such manifestations early for prompt diagnosis and prevention of complications. LEARNING POINTS: Recognise haemoptysis as the manifestation of thoracic aortic pseudoaneurysm.Early diagnosis and treatment are crucial due to high rate of complications and mortality.Trauma and cardiovascular surgery are the most common cause for thoracic aortic pseudoaneurysm; however, sometimes it can occur due to atherosclerosis.
RESUMO
Babesiosis is a potentially life-threatening tick-borne parasitic infection. Severe disease in splenectomized individuals may require exchange transfusion. A 58-year-old male with a history of splenectomy presented with 2 weeks of subjective fever, weakness, and abdominal pain. He denied any rashes, tick bites, or recent travel. He had a motor vehicle accident a few years ago and had undergone an emergency splenectomy. On examination, the patient was febrile (39.3 °C), tachycardic (106/min), and jaundiced. Labs revealed anemia and thrombocytopenia. Computed tomography (CT) abdomen revealed asplenia. As it was summer, there was concern for a tick-borne illness. A peripheral smear showed schistocytes, and labs revealed hyperbilirubinemia, high lactate dehydrogenase (LDH), low haptoglobin, and reticulocytosis (13%), consistent with hemolysis. Testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), Ehrlichia, Borrelia, Anaplasma, and viral hepatitis was negative. Antibody testing for Babesia microti was positive. A blood parasite smear confirmed Babesia microti with a parasitemia of 9.5%. The patient received intravenous azithromycin and atovaquone for severe babesiosis. On day 2 of hospitalization, parasitemia increased to 14.7%. Hemoglobin and platelets dropped further on day 3. His parasite load remained consistently above 10% despite medical treatment. A decision was made for a red blood cell (RBC) exchange transfusion for severe disease, which was performed on the fourth day of hospitalization. Clinical improvement was seen after one session of exchange RBC transfusion. Hemoglobin remained stable, and thrombocytopenia improved 1 day after RBC exchange transfusion. Parasitemia dropped to 1.2% after 4 days of exchange transfusion, and azithromycin was switched to oral. He received 9 days of inpatient azithromycin and atovaquone. He was discharged with a plan to continue the oral antimicrobials for 3 more weeks. Asplenia and parasitemia > 10% are associated with severe babesiosis. Asplenia, in particular, is associated with severe infection, hospitalization, and prolonged duration of therapy. Exchange transfusion in severe babesiosis can be lifesaving.
RESUMO
Left ventricular non-compaction cardiomyopathy (LVNC), or non-compaction cardiomyopathy (NCCM), is defined by pronounced left ventricular trabeculations and deep intertrabecular recesses connecting with the ventricular cavity. Patients with NCCM can be asymptomatic or have severe complications, including heart failure, arrhythmias, thromboembolism, and sudden cardiac death. Our case discusses a patient with shortness of breath who was found to have a newly decreased ejection fraction. The workup revealed non-ischemic cardiomyopathy and cardiac MRI showed hyper-trabeculations consistent with NCCM. The patient was started on oral anticoagulation and guideline-directed medical therapy (GDMT) and discharged with an event monitor. NCCM stands as a relatively rare and enigmatic condition, often veiled in ambiguity. The absence of standardized diagnostic and management protocols further complicates its clinical landscape. While echocardiography is the primary diagnostic tool, its tendency for under-diagnosis poses a significant challenge. Conversely, advanced imaging modalities like cardiac MRI may lead to instances of overdiagnosis. Treatment approaches are non-specific, incorporating GDMT, anticoagulation, implantable cardioverter-defibrillator placement, and genetic testing paired with counseling. Prioritizing genetic research is crucial to uncover tailored therapeutic interventions. Establishing consensus guidelines and refining diagnostic accuracy are pivotal steps toward mitigating the risks associated with under and over-diagnosis.
RESUMO
Adult-onset Still's disease (AOSD) stands as a perplexing condition with diverse clinical manifestations, posing significant diagnostic challenges for healthcare professionals. This case report delves into the clinical trajectory, diagnostic challenges, treatment strategies, and outcomes experienced by a 67-year-old female with AOSD. This report advocates for considering AOSD as a potential diagnosis in patients presenting with systemic inflammatory symptoms, especially when other conditions have been ruled out. It highlights the complexity of AOSD and the importance of interdisciplinary collaboration, close monitoring, and personalized treatment strategies to optimize patient outcomes.
RESUMO
Introduction: Blue rubber bleb nevus syndrome is a rare disorder of venous malformations, with around 200 cases reported. We present a case of Mycobacterium xenopi infection in a patient with blue rubber bleb nevus syndrome. Case Description: A 40-year-old female with blue rubber bleb nevus syndrome, asthma, and bronchiectasis came to the pulmonology clinic with shortness of breath and a cough. She was recently admitted for a bronchiectasis exacerbation but continued to have a worsening productive cough and fevers. The most recent CT scan of the chest showed interval stable right upper lobe fibrocavitary disease, demonstrating gradual progression over two years. She had occasional positive cultures for Mycobacterium Avium Complex and M. xenopi one year previously, assumed to be a colonizer and not treated. Most recent hospital cultures were negative for bacteria and an acid-fast bacilli smear. She was sent to the emergency department for bronchiectasis exacerbation and returned to the clinic six weeks later with two sputum cultures growing M. xenopi. It was decided to treat M. xenopi as this was likely the cause of her cavitary lung lesion and frequent infections. Azithromycin, rifampin, and sulfamethoxazole/trimethoprim were initiated. Intravenous amikacin was added later on. She finally had a right partial lung resection done after one year at an outside hospital. She was on and off antibiotics for M. xenopi for approximately three years with negative repeat cultures for non-tuberculous mycobacteria. Conclusion: Due to the high mortality of M. xenopi infections (which can be as high as 69%), treatment of at least twelve months is recommended. To our knowledge, this is the first reported case of M. xenopi in a patient with blue rubber bleb nevus syndrome. LEARNING POINTS: The decision to initiate treatment for non-tuberculous mycobacterium infections is often challenging with prolonged treatment.Lifetime monitoring is required in patients with blue rubber bleb nevus syndrome, which can have pulmonary complications.M. xenopi has the highest mortality among non-tuberculous mycobacterium infections and requires at least 12 months of treatment.
RESUMO
Posterior scleritis is a rare inflammatory eye condition affecting the posterior segments of the sclera and is more prevalent in females. Its clinical presentation, often nonspecific, includes ocular pain, headache, and vision loss. Misdiagnosis is common due to a lack of specific symptoms posing a potential threat to vision. The etiology is often tied to rheumatic diseases, such as rheumatoid arthritis (RA), systemic erythematous lupus (SLE), and anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis. Posterior scleritis poses diagnostic challenges, mimicking many other ocular conditions, hence necessitating a thorough clinical eye exam. Laboratory studies, including inflammatory markers and markers of rheumatic diseases, may identify underlying systemic diseases. Imaging, including B-scan ultrasound and magnetic resonance imaging (MRI), aids in accurate diagnosis. Treatment involves non-steroidal anti-inflammatory drugs (NSAID), as well as topical corticosteroids for mild disease and systemic corticosteroids for severe disease. Biologic therapy has become increasingly significant for refractory cases. A multidisciplinary approach involving ophthalmology and rheumatology is crucial in the management of this potential sight-threatening disease. This case report highlights a 46-year-old woman with a history of RA-associated posterior scleritis.
RESUMO
Pleural effusions can be secondary to several different etiologies. Sometimes, they can be related to hypothyroidism. We present a case of massive pleural effusion resulting from hypothyroidism. A 75-year-old male with a history of liver cirrhosis, hypothyroidism, and medication non-adherence presented to the emergency department (ED) with shortness of breath and altered mental status. Physical exam and chest imaging were consistent with right-sided pleural effusion. Effusion was exudative. Multiple recurrences complicated the hospitalization despite thoracentesis and pleurodesis. Labs revealed hypothyroidism, and finally, the patient was started on hormone replacement, resulting in the resolution of the effusion. Pleural effusion is a rare manifestation of hypothyroidism, thought to be mediated by vascular endothelial factors. Pleural fluid analysis shows both exudative and transudative patterns. Hormonal replacement is the mainstay of treatment. Clinicians need to be aware of the rare etiologies of pleural effusion. Depending on the patient's presentation, due work-up should be done to ensure a timely diagnosis and management.
RESUMO
Introduction: Combination-based adjuvant chemotherapy utilising capecitabine and oxaliplatin is widely used in gastric cancer treatment. Rare but severe cardiac events such as prolonged QT, cardiac arrest and cardiogenic shock can result from their use. Case description: A 45-year-old female with gastric adenocarcinoma was started on capecitabine-oxaliplatin chemotherapy one week before presenting to the emergency department with weakness. Blood pressure was 78/56 mmHg, heart rate 140 bpm and oxygen saturation 85%. She became unresponsive with pulseless ventricular fibrillation; CPR was initiated with immediate intubation. She received two shocks with a return of spontaneous circulation. Laboratory tests revealed serum potassium (3.1 mmol/l), magnesium (1.1 mg/dl) and troponin (0.46 ng/ml). An EKG revealed sinus tachycardia with a prolonged QT interval (556 ms). The combined effects of capecitabine, oxaliplatin and electrolyte abnormalities likely contributed to the QT prolongation. An echocardiogram demonstrated an ejection fraction of 10%-15%. An emergent right-heart catheterisation showed right atrial pressure of 10 mmHg and pulmonary artery pressure of 30/18 mmHg; cardiac output and index were not recorded. An intra-aortic balloon pump was placed, and she was admitted to the ICU for cardiogenic shock requiring norepinephrine, vasopressin and dobutamine. A repeat echocardiogram showed a significantly improved ejection fraction of 65%, and she was discharged. Discussion: Capecitabine and oxaliplatin cardiotoxicity is an exceedingly rare occurrence, with both drugs reported to cause QT prolongation. Conclusion: Healthcare providers must recognise the QT prolongation effects of capecitabine and oxaliplatin, leading to life-threatening cardiac arrhythmias. LEARNING POINTS: Recognise the QT-prolonging effects of capecitabine and oxaliplatin-based chemotherapy.Recognise that cardiogenic shock and cardiac arrest with capecitabine and oxaliplatin-based chemotherapy can occur in individuals with benign cardiac history, especially early in treatment.
RESUMO
Non-typhoidal Salmonella typically presents with gastroenteritis. However, an invasive Salmonella infection, which may be typically seen in immunocompromised patients, has a propensity for aortic involvement, especially in patients with risk factors for atherosclerosis. Here we present a 60-year-old female with multiple comorbid conditions and currently on immunosuppressants for rheumatoid arthritis, who presented with nausea, vomiting, and fever of three weeks duration and was found to have Salmonella bacteremia. Blood cultures were positive for Salmonella enterica. Computed tomography (CT) abdomen with contrast was concerning for mycotic aortitis. The patient underwent endovascular repair of an aortic ulcer and was treated with a six-week course of ceftriaxone. Mycotic aneurysm is a rare but potentially fatal complication of invasive Salmonella infection. It occurs typically in older men with atherosclerotic risk factors. It mostly presents as fever, back pain, and/or abdominal pain. Our patient was a middle-aged female who presented with non-specific symptoms. CT angiogram is the diagnostic modality of choice and treatment may require surgical vascular repair and long-term antibiotics. A high level of suspicion is needed to diagnose Salmonella-related mycotic aneurysm/aortitis. Early diagnosis and treatment may improve the mortality.
RESUMO
Subacute thyroiditis (SAT) is an inflammatory disease of the thyroid gland. It can present with overlapping features of other etiology of thyroiditis. It can present with thyroid enlargement and systemic symptoms such as fever as well as neck pain and may be confused with infectious thyroiditis. It can be difficult to diagnose and present as fever of unknown origin (FUO). A good history, physical examination, laboratory investigation, as well as imaging may aid in the correct diagnosis and prevent the inappropriate use of antibiotics. Treatment is usually with nonsteroidal anti-inflammatory drugs (NSAIDs) as well as corticosteroids. We herein present a case of SAT presenting as FUO. We highlighted the importance of proper clinical evaluation, the importance of thyroid imaging, and how to differentiate other forms of thyroiditis.
RESUMO
Neuroblastoma is the most common embryonal tumor of childhood and has a variable presentation. Stage 4S neuroblastoma, described as a localized primary tumor in an infant with metastasis to skin, liver, or bone marrow, is an exception to the poor prognosis seen in widespread metastasis of neuroblastoma. Survival in infants with this stage of the disease is over 90%. Stage 4S with massive liver involvement, however, confers a poor prognosis. We need more research on the optimum treatment modality for patients with Stage 4S disease and massive hepatomegaly to improve patient outcomes.
RESUMO
A fecalith is a common cause of acute appendicitis, and laparoscopic surgery is the mainstay of its management. Literature review shows that a fecalith may be retained in the gut following a laparoscopic appendectomy in some rare cases. In most cases, the fecalith becomes symptomatic with time due to the formation of an abscess, fistulous tract, or inflammation of the appendicular stump (stump appendicitis). We report a case of retained appendicular fecalith presenting with symptoms similar to acute appendicitis, 15 years after laparoscopic appendectomy.
RESUMO
OBJECTIVE: To explore the knowledge and perceptions about pre-diabetes screening and management amongst physicians, final year medical students, and patients. METHODS: The cross-sectional observational study was conducted at Shifa International Hospital, Shifa Foundation Clinic and Shifa College of Medicine, Islamabad, Pakistan, from November 2017 to February 2018. A structured questionnaire was used to assess doctors' and final year medical students' knowledge about screening and management of pre-diabetes. A group of patients were also interviewed about pre-diabetes awareness and their primary resources for health-related information. Data was analysed using SPSS 23. RESULTS: Of the 267 participants, there were 85(32%) doctors, 82(31%) medical students and 100(37%) patients. Only 61(71.8%), 44(51.7%) and 34(39.8%) physicians and 53(64.6%), 30(36.5%) and 26(31.6%) students could accurately identify impaired fasting blood glucose, glycated haemoglobin and impaired glucose tolerance criteria for pre-diabetes, respectively. Regarding risk factors for pre-diabetes screening, ethnicity, cardiovascular diseases and gestational diabetes were identified by 8(9.4%), 6(7.1%) and 9(10.6%) physicians and 10(12.2%), 6(7.3%) and 15(18.3%) students, respectively. There was no statistically significant relation of correct identification of pre-diabetes criteria with specialties, designations and years of experience post-qualification (p>0.5). Only 3(3%) patients were aware of pre-diabetes or borderline diabetes. CONCLUSIONS: Knowledge and perception of doctors, medical students and patients about pre-diabetes was found to be deficient. Efforts are required to reinforce its identification and management at all levels..
