Mycobacterium celatumis a nontuberculous mycobacterium shown to cause symptoms similar to pulmonaryM. tuberculosis. Certain strains have been shown to cross-react with the probes used to detectM. tuberculosis, making this a diagnostic challenge. We present a 56-year-old gentleman who developed signs and symptoms of lung infection with computed tomography scan of the chest showing right lung apex cavitation. Serial sputum samples were positive for acid-fast bacilli and nucleic acid amplification testing identifiedM. tuberculosisribosomal RNA, resulting in treatment initiation. Further testing with high performance liquid chromatography showed a pattern consistent withM. celatum. This case illustrates the potential forM. celatumto mimicM. tuberculosisin both its clinical history and laboratory testing due to the identical oligonucleotide sequence contained in both. An increasing number of case reports suggest that early reliable differentiation could reduce unnecessary treatment and public health intervention associated with misdiagnosed tuberculosis.

OBJECTIVE: To describe a case of a medication bezoar and to review the clinical presentation, diagnosis, risk factors, pathogenesis, complications, and treatment of medication bezoars. DATA SOURCES AND STUDY SELECTION: A MEDLINE search (January 1966–December 1997) of the English-language literature pertaining to bezoars was performed. These articles were scanned, and literature specifically discussing medication bezoars was selected. Additionally, the reference sections of pertinent review and case reports were scanned for additional relevant literature. DATA SYNTHESIS: Bezoars are concretions of foreign material within the body. In the case of medication bezoars, these concretions occur within the digestive tract and are composed of medications and/or medication vehicles. Rarely, however, is bezoar formation solely due to a medication. In nearly all reported cases the patient had one or more significant risk factors that contributed to bezoar formation. The exact method by which medication bezoars form is dependent on the particular type or combination of medications involved. Bezoar formation may be associated with significant complications for the patient due to the presence of the bezoar and because of the effects of the medication within the bezoar. Treatment of medication bezoars depends largely on the location and the cause of the bezoar. CONCLUSIONS: Medication bezoars are a rare but potentially serious complication of medication use in certain patients. These patients often present with signs and symptoms consistent with an obstruction of the gastrointestinal tract and represent an even greater diagnostic challenge due to the rarity of this complication. These patients also face significant complications from both the bezoar and the medication within the bezoar. To date, treatment of medication bezoars involves mainly physical manipulation of the bezoar through lavage, endoscopic removal, or, in most cases, surgical removal.

Abstract Background: Clinical history and exam findings obtained during the initial evaluation of a patient presenting with neuromuscular complaints are often pivotal in the formulation of diagnostic and therapeutic approach. However, disorders that have diverse overlapping manifestations may pose a diagnostic challenge for clinicians. Although case reports can be valuable sources for guiding clinical decisions, retrieval of applicable information from them is not straightforward. Methods: In this paper, we propose a feature-extraction-based method to improve the efficacy and effectiveness of this process. The accuracy of the method in linking clinical presentations to correct diagnoses is examined using 30 case reports of amyotrophic lateral sclerosis, monomelic amyotrophy, and inclusion body myositis, obtained from PubMed Central Open Access Subset. Results: The results show that feature extraction not only augments semantic classification with explainability but also improves the performance. Conclusions: If developed further, the approach can be used to provide clinicians with decision support in challenging clinical situations.

SummaryCase reports cited in Medline or Biological Abstracts (1966-1996) were reviewed to evaluate the impact of vitamin K1 dietary intake on the stability of anticoagulant control in patients using coumarin derivatives. Reported nutrient-drug interactions cannot always be explained by the vitamin K1 content of the food items. However, metabolic data indicate that a consistent dietary intake of vitamin K is important to attain a daily equilibrium in vitamin K status. We report a diet that provides a stable intake of vitamin K1, equivalent to the current U.S. Recommended Dietary Allowance, using food composition data derived from high-performance liquid chromatography. Inconsistencies in the published literature indicate that prospective clinical studies should be undertaken to clarify the putative dietary vitamin K1-coumarin interaction. The dietary guidelines reported here may be used in such studies.

Abstract Background Chronic ocular graft-versus-host disease (oGVHD) is an ocular comorbidity of graft-versus-host disease (GVHD) that usually occurs concurrently with systemic manifestations. Failure to detect and treat oGVHD in its early stages may lead to progression of ocular signs and symptoms leading to oGVHD that is refractory to conventional treatment. Case presentation We report the clinical course of a 19-year-old male and a 59-year-old female with severe and progressive chronic oGVHD without concurrent systemic signs of chronic graft-versus-host disease (cGVHD). Although their systemic conditions had been stable, both suffered from severe oGVHD and were referred to our clinic. Both cases exhibited marked improvement in conjunctival inflammation and fibrotic changes after amniotic membrane transplantation (AMT). Both cases underwent keratoplasty eventually to stabilize ocular surface conditions and to improve visual function. Conclusions We reported the clinical outcomes of 2 cases of chronic oGVHD without concurrent systemic comorbidities that were treated with AMT. The clinician should be aware that cGVHD may persist in target organs even in the absence of concurrent systemic comorbidities following seemingly successful systemic treatment. A multidisciplinary team approach is essential in the early detection and therapeutic intervention for chronic oGVHD.

Abstract Background Subacute sclerosing panencephalitis (SSPE) is a potentially lethal complication of measles infection. Neurological complications take years to manifest after primary viral infection of brain and can lead to blindness in some individuals. Findings A 13-year-old female patient with history of Bell’s palsy 2 months prior, presented with rapidly progressing necrotizing retinitis in both eyes. Soon after, she was unable to walk, developed myoclonic jerks, altered sensorium and loss of bowel and bladder control. Her clinical history, CSF IgG measles antibody analysis, MRI brain and EEG findings confirmed the diagnosis of SSPE. Conclusion SSPE in our case presented as Bell’s palsy and sudden painless diminution of vision due to ocular involvement, and developed full blown disease within 2 months. SSPE can present as a diagnostic challenge and warrants early identification and referral for timely diagnosis and management.

Abstract Background This case report demonstrates pericardial effusion, acute pericarditis, and cardiac tamponade in an otherwise healthy woman who had a positive test result for coronavirus disease 2019. Few case reports have been documented on patients with this presentation, and it is important to share novel presentations of the disease as they are discovered. Case presentation A Caucasian patient with coronavirus disease 2019 returned to the emergency department of our hospital 2 days after her initial visit with worsening chest pain and shortness of breath. Imaging revealed new pericardial effusion since the previous visit. The patient became hypotensive, was taken for pericardial window for cardiac tamponade with a drain placed, and was treated for acute pericarditis. Conclusion Much is still unknown about the implications of coronavirus disease 2019. With the novel coronavirus disease 2019 pandemic, research is still in process, and we are slowly learning about new signs and symptoms of the disease. This case report documents a lesser-known presentation of a patient with coronavirus disease 2019 and will help to further understanding of a rare presentation.

OBJECTIVE To review the clinical evidence for routine use of bleomycin test dosing. DATA SOURCES English-language review articles, references from retrieved articles, case reports, and clinical trials were identified from a MEDLINE literature search (1966–July 2005). Key search terms included bleomycin, test dose, anaphylactic reactions, and hypersensitivity. Information from an unpublished E-mail survey, the manufacturer, and the Internet was also used. DATA SYNTHESIS Early clinical trials and isolated case reports suggest that bleomycin-induced acute hypersensitivity reactions occur in 1% of patients with lymphoma and <0.5% of those with solid tumors. The reactions are mainly characterized by high-grade fever, chills, hypotension, and in a few cases, cardiovascular collapse, which can lead to death. The exact mechanism of these reactions is unclear, but is thought to be related to the release of endogenous pyrogens from the host cells. Evidence does not suggest any correlation between doses and the onset or severity of the reactions. Supportive care, including hydration, steroids, antipyretics, and antihistamines, may resolve the symptoms. However, it may not completely prevent recurrences. CONCLUSIONS The incidence of acute hypersensitivity or hyperpyrexic reactions associated with bleomycin is very low, but the reaction is potentially fatal. Clinicians should monitor their patients for any signs and symptoms of acute hyperpyrexic reactions during bleomycin administration. Since the onset of the reactions can occur with any dose of bleomycin and at any time, routine test dosing does not seem to predict when drug reactions may occur.

Cutaneous leishmaniasis is rare in Bangladesh although very few case reports are seen since last few years. But Visceral Leishmaniasis (kala azar) and PKDL are common in this region. In country like ours where tuberculosis and leprosy are more prevalent Cutaneous Leishmaniasis is very likely to be mistreated as Cutaneous tuberculosis especially lupus vulgaris or leprosy. Cases of Cutaneous Leishmaniasis (CL) are usually imported to Bangladesh from other endemic countries. A patient from an endemic area of Cutaneous Leishmaniasis, a non-healing nodulo-ulcerative lesion on exposed part of the body, dermal infiltration with lymphocytes, histiocytes and plasma cells and demonstration of intracellular parasites in lesional skin establish the diagnosis of Cutaneous Leishmaniasis. We present a case of Cutaneous Leishmaniasis in a Bangladeshi adult working in Saudi Arabia for more than 15 years. He presented with multiple ulcerative lesions on nasal bridge, right ear lobule and dorsum of right ring finger. The patient’s clinical history, morphology of the lesions and laboratory analysis were consistent with Cutaneous Leishmaniasis, a rare entity for Bangladesh.Bangladesh J Medicine Jul 2014; 25 (2) : 78-80

Background and Aims. Cardiac outpouchings encounter a series of distinct congenital or acquired entities (i.e. aneurysms, pseudoaneurysms, diverticula, and herniations), whose knowledge is still poorly widespread in clinical practice. This review aims to provide a comprehensive overview focusing on definition, differential diagnosis, and prognostic outcomes of cardiac outpouchings, as well as further insights on therapeutic options, in order to assist physicians in the most appropriate decision-making. Methods. The material reviewed was obtained by the following search engines: MEDLINE (PubMed), EMBASE, Google Scholar, and Clinical Trials databases, from January 1966 until March 2021. We searched for the following keywords (in title and/or abstract): (“cardiac” OR “heart”) AND (“outpouching” OR “outpouch” OR “aneurysm” OR “pseudoaneurysm” OR “false aneurysm” OR “diverticulum” OR “herniation”). Review articles, original articles, case series, and case reports with literature review were included in our search. Data from patients with congenital or acquired cardiac outpouchings, from prenatal to geriatric age range, were investigated. Results. Out of the 378 papers initially retrieved, 165 duplicates and 84 records in languages other than English were removed. Among the 129 remaining articles, 76 were included in our research material, on the basis of the following inclusion criteria: (a) papers pertaining to the research topic; (b) peer-reviewed articles; (c) using standardized diagnostic criteria; and (d) reporting raw prevalence data. Location, morphologic features, wall motion abnormalities, and tissue characterization were found to have a significant impact in recognition and differential diagnosis of cardiac outpouchings as well as to play a significant role in defining their natural history and prognostic outcomes. Conclusions. Careful recognition of cardiac outpouchings remains a diagnostic challenge in clinical practice. Due to a broad cluster of distinctive and heterogeneous entities, their knowledge and timely recognition play a pivotal role in order to provide the most appropriate clinical management and therapeutic approach.

Background: A mass in the right iliac fossa is a common diagnostic problem encountered in clinical practice, requiring skill in diagnosis. Methods: 100 patients with signs and symptoms of right iliac fossa mass admitted in Hospital were identified and were studied by taking detailed clinical history, physical examination and were subjected to various investigations like x ray erect abdomen, chest x-ray, contrast x-ray . Result: In this study of out of 100 cases, 65.00% of cases were related to appendicular pathology either in the form of appendicular mass or appendicular abscess. There were 12.00% cases of ileocaecal tuberculosis. Conclusion: Appendicular lump remains the most common cause for right iliac fossa pain. Ileocaecal tuberculosis is one of the most important differential diagnoses for pain abdomen. Keywords: Appendicular Mass, Ileocaecal Tuberculosis, Carcinoma Caecum, Right Iliac Fossa Mass.
