RESUMEN
Introduction: Blood culture-negative infective endocarditis is the condition in which a causative organism cannot be identified after inoculation of at least three samples using standard blood-culture systems for 7 days. It has a low reported incidence of about 2.5-31%. Causes may be infectious or non-infectious; use of prior antibiotic therapy is usually the leading factor. Case presentation: The authors present a case of true culture-negative endocarditis involving the mitral valve, with multiple foci of spread including brain, spleen, liver, and Intervertebral disc, which remained persistent despite treatment with intravenous broad-spectrum antibiotics on an inpatient and outpatient basis but eventually improved after upgrading alternative broad-spectrum antibiotic for an extended duration. The patient had complications in the form of a flail mitral valve with persistent mitral regurgitation, requiring mitra-clip placement. Discussion: Positive blood culture is one of the major diagnostic criteria to establish infective endocarditis. Patients may have persistent negative cultures due to previous antibiotic use, the presence of fastidious organisms, or the use of inappropriate techniques or media. Involvement of a multidisciplinary team, use of multimodal investigations, and appropriate antibiotic stewardship are crucial. Extended duration of treatment and upgrading antibiotics can be helpful next steps in highly suspicious cases. With multifocal spread as in our case, it further becomes challenging to control and treat the infection as it is frequently connected with higher morbidity and mortality. Conclusion: Blood culture-negative endocarditis is an entity that can present with early complications. It is diagnostically and therapeutically challenging to treat such patients. Multimodal approaches for early diagnosis and appropriate treatment are crucial owing to its high morbidity and mortality.
RESUMEN
Diesel fuel aspiration can occasionally result in an uncommon but potentially deadly condition called chemical pneumonitis. Case presentation: In this case study, a 16-year-old boy gave a history of diesel fuel siphoning from a motor vehicle tank, which brought him to our emergency room. He complained of coughing, breathing difficulties, and chest discomfort upon admission to the hospital. Patchy bilateral parenchymal lung opacities consistent with acute chemical pneumonitis were seen in radiological imaging tests. Treatment included supportive care, oxygen supplementation, and intravenous antibiotics. The patient's symptoms improved gradually throughout his hospitalization, and he was eventually discharged home with a good prognosis. Clinical discussion: Siphoning is a common practice in developing countries like Bangladesh. Workers at automobile transfer hydrocarbon products from one vehicle to other. However, its aspiration can cause a pneumonia like features and may wrongly misdiagnose. Diagnosis is made mainly on history taking. Conclusion: Physicians ought to know that patients exposed to diesel fuel may develop chemical pneumonitis, and they should consider this for an early diagnosis and effective treatment that can lead to favourable outcomes.
RESUMEN
Nepal is a country of Himalayas including Mt Everest, the tallest mountain in the world, where a lot of people travel to high altitudes. Significant number of people develop high-altitude illness which includes acute mountain sickness (AMS), high altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE) leading even to death. Addressing this issue demands more efforts on both the preventive and treatment aspects to decrease the sufferings of people in this modern time of advanced healthcare and technology.
RESUMEN
Iodine deficiency is a major cause of thyroid disorders worldwide. Nepal lies in the endemic area of iodine deficiency which was previously referred to as Himalayan goiter belt, with high prevalence of iodine deficiency disorders including goiter, cretinism and hypothyroidism. With effective implementation of universal salt iodization program, Nepal has a successful public health story to share having drastically reduced the iodine deficiency disorders. Moreover, challenge has appeared with rising number of excess iodine states. Thyroid dysfunction is growing higher and the increasing proportion of hyperthyroidism is particularly concerning. Time has come for us to suitably review the standards of salt iodization and control the increasing number of cases with thyroid dysfunction by the coordinated efforts of all stakeholders, along with sustaining the optimal level of iodine.
