A rare cause of left ventricular outflow tract mass in infancy: Cardiac papillary fibroelastoma

Haranal M, Febrianti Z, Latiff HA, Rahman SA, Sivalingam S

Asian Cardiovasc Thorac Ann, 2021 Oct;29(8):816-818.

PMID: 33641433 DOI: 10.1177/0218492321998500

Primary cardiac tumors are one of the rare causes of intracardiac masses in pediatric population. Cardiac papillary fibroelastomas are benign cardiac tumors with predilection for valvular endocardium, and the presentation is dictated by the cardiac structure involved and the tumor characteristics. We report an infant with cardiac papillary fibroelastoma manifesting as an asymptomatic left ventricular outflow tract mass. This case is being presented to emphasize the rare occurrence of cardiac papillary fibroelastoma in pediatric population and to be cognizant of this entity when considering differential diagnosis of intracardiac masses in this subgroup.

Fulltext Understanding hyperemesis gravidarum

Loh KY, Sivalingam N

Med J Malaysia, 2005 Aug;60(3):394-9; quiz 400.

PMID: 16379204

Nausea and vomiting are common in early pregnancy affecting 70-80 percent of pregnant mothers. In a majority of women vomiting begins between 4-7 weeks of pregnancy. Nausea and vomiting are usually mild and self-limiting, however some of the mothers have a more profound course which lead to hyperemesis gravidarum. Careful clinical evaluation is necessary to exclude underlying medical illnesses or non pregnancy related causes of severe vomiting. Hyperemesis gravidarum poses health risk to both mother and baby, therefore prompt treatment should be initiated without delay. Non pharmacotherapy such as dietary modification and emotional support are useful. Pharmacotherapy with antiemetics, pyridoxine, methylprednisolone are effective and relatively safe. Severe hyperemesis with dehydration and electrolyte imbalance may need hospitalisation for electrolyte and fluid replacement.

Fulltext A rare case of chondrosarcoma of the clavicle

Amalourde A, Vinayaga P, Naveed N, Jamal A, Looi LM, Sengupta S

Med J Malaysia, 2004 Dec;59 Suppl F:60-2.

PMID: 15941166 MyJurnal

Although all types of tumour and tumour-like conditions have been described to occur in the clavicle, they only contribute to less then 0.5% of all skeletal tumours. The incidence of primary chondrosarcoma of the clavicle is extremely rare. To our knowledge it has not been reported in Malaysia. We would like to highlight the possibility of chondrosarcoma as a differential diagnosis for a clavicular lesion.

Fulltext Practical way of creating differential diagnoses through an expanded VITAMINSABCDEK mnemonic

Zabidi-Hussin ZA

Adv Med Educ Pract, 2016;7:247-8.

PMID: 27217805 DOI: 10.2147/AMEP.S106507

Having an organized, structured thinking process is critical in medicine. It is through this thinking process that enables one to go through the method of history-taking, which will eventually lead to making a definitive diagnosis and all other processes that follow. The use of mnemonic has been found to be useful for this purpose. The mnemonic VITAMINSABCDEK, is a convenient and practical way to assist in expanding the differential diagnoses and covers all possible causes of an illness. It is also easy to remember, as the vitamins whose letters are represented in this mnemonic cover the entire range of vitamins known.

Although the diagnosis of thymolipoma has improved with the introduction of computerized tomography (CT), variations in CT appearance are still being described; this paper describes a case which resembled a lipoma. The CT features of thymolipoma are discussed with special reference to the differential diagnosis. Surgical excision should be considered for patients who are found to exhibit a fatty intrathoracic mass on CT.

Metastatic follicular thyroid carcinoma: a case report

Sathasivam H, Loh YM, Saw CL, Khalid N

Gerodontology, 2017 Jun;34(2):276-279.

PMID: 27384017 DOI: 10.1111/ger.12240

OBJECTIVE: A case of oral metastatic follicular thyroid carcinoma is presented.

BACKGROUND: Metastatic tumours are more frequent in older individuals and can be the only sign/symptom of an undiagnosed primary malignancy.

CASE REPORT: A 69-year-old lady presented with an enlarging mandibular swelling. Incisional biopsy and imaging studies were suggestive of metastatic follicular thyroid carcinoma.

CONCLUSION: Metastatic tumours should be considered in the differential diagnosis of mandibular swellings especially in older individuals.

An Expansile Well-defined Radiolucency in Anterior Mandible: Case Presentation with Treatment Approach and Literature Update

Arora S, Urs AB, Choudhary Z

Gulf J Oncolog, 2017 Jan;1(23):77-81.

PMID: 28272008

A 15-year-old Indian male patient presented with a history of pain and swelling in left mandible. Imaging studies revealed a well-defined unilocular radiolucency in the body of the mandible. Patient also gave the past history of the surgery of the jaws, which was histopathologically diagnosed as dentigerous cyst. Following this patient underwent incisional biopsy and later excisional biopsy. The histopathologic diagnosis for incisional biopsy was unicystic ameloblastoma but final diagnosis was dentinogenic ghost cell tumor for the excised tissue. To the best of our knowledge, this appears o be the first case of dentigerous cyst transforming into dentinogenic ghost cell tumor. The clinical presentation of the case, differential diagnosis and treatment modalities are being discussed.

Fulltext Benign Lymphoepithelial Cyst: An Unusual Cause of Parotid Swelling in Two Immunocompetent Patients

Thong HK, Athar PPSH, Mustaffa WMW

Open Access Maced J Med Sci, 2019 Jul 15;7(13):2142-2145.

PMID: 31456841 DOI: 10.3889/oamjms.2019.577

BACKGROUND: Lymphoepithelial cysts, which are benign and slow-growing tumours, usually involve the head and neck regions. Benign lymphoepithelial cysts (BLECs) are the most common cause of parotid swelling in human immunodeficiency virus (HIV)-positive patients and are less common in immunocompetent patients.

CASE PRESENTATION: Here, we present two cases of immunocompetent patients with long-standing, progressively enlarging parotid swelling. Postoperative histopathological examination of these patients revealed features of BLEC.

CONCLUSION: Wide surgical excision is the gold standard for treatment and recurrences is rare. These cases are of particular interest because of the rarity of BLEC in HIV-negative patients and highlight an important differential diagnosis of parotid swelling.

Fulltext About clinicopathological conference and its' practice in the School of Medical Sciences, USM

Hassan S

Malays J Med Sci, 2006 Jul;13(2):7-10.

PMID: 22589598

The clinicopathological conference, popularly known as CPC primarily relies on case method of teaching medicine. It is a teaching tool that illustrates the logical, measured consideration of a differential diagnosis used to evaluate patients. The process involves case presentation, diagnostic data, discussion of differential diagnosis, logically narrowing the list to few selected probable diagnoses and eventually reaching a final diagnosis and its brief discussion. The idea was first practiced in Boston, back in 1900 by a Harvard internist, Dr. Richard C. Cabot who practiced this as an informal discussion session in his private office. Dr. Cabot incepted this from a resident, who in turn had received the idea from a roommate, primarily a law student.

Fulltext An Infratemporal Meningioma: A Diagnostic Dilemma

Kaur A, Ali R, Omar E, Hashim H

J Radiol Case Rep, 2021 Jan;15(1):1-10.

PMID: 33717402 DOI: 10.3941/jrcr.v15i1.3898

A 46-year-old male presented with painless, recurrent bilateral ear discharge and an enlarging right temporal swelling. There were no neurological deficits. Imaging revealed an enhancing, soft tissue mass at the right infratemporal region involving the right temporalis muscle with a small, enhancing intradural component and associated hyperostosis of the greater wing of the right sphenoid bone. Tumour debulking of the right temporalis tumour was performed. Tumour invasion of the right temporalis muscle was noted intraoperatively. Histopathological result was consistent with fibrous meningioma WHO Grade 1 involving surgical resection margins. Follow-up MRI revealed residual right temporal extracranial component. Thus, plans were made for a second stage tumour debulking, however at time of writing, surgery had not been performed. This case highlights the differing appearances of the common meningioma occurring extracranially with elaboration of its differential diagnosis and management.

Evaluation of a Rapid Kit for Detection of IgM against Leptospira in Human

Rao M, Amran F, Aqilla N

Can J Infect Dis Med Microbiol, 2019;2019:5763595.

PMID: 30881530 DOI: 10.1155/2019/5763595

Introduction: Leptospirosis is an acute febrile illness, known for its protean clinical manifestations and the challenge in differentiating from other infectious diseases. Standardized confirmatory test is antibody dependent and not accessible by the suburban community. This study measures efficiency of an immune-chromatographic assay, Leptocheck WB, in detecting acute leptospirosis.

Methods: A total of 142 sera were used for kit evaluation. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated by comparing rapid kit results with gold standard laboratory, microscopic agglutination test (MAT).

Results: We found this rapid kit to have a sensitivity and specificity of 66.6% and 78.9%, respectively, whereas the PPV and NPV of the kit appeared to be 73.3% and 73.2%, respectively.

Discussion: Test efficiency of this rapid kit is reasonable. It is specific in detecting leptospiral antibody and assures clinician of accurate diagnosis by having higher PPV and NPV. It is prompt and efficient in comparison with conventional methods in assisting differential diagnosis. High sensitivity and specificity leptospirosis rapid test is indeed a crucial measure to assist the diagnosis of acute undifferentiated febrile illnesses.

Neurological disorders (NDs) are often fatal to horses. Thus, symptoms of equine NDs commonly indicate euthanasia. Current diagnostic approaches for equine NDs is based on clinical signs, differential diagnoses, analysis of cerebrospinal fluid (CSF), assessment of histopathological lesions, and imaging. However, advances in biofluid biomarkers in the diagnosis of human neurological diseases can potentially be applied to equine NDs. In this review, we described the established human blood and CSF neurobiomarkers that could potentially be used to diagnose equine NDs.
