RATIONALE: Septo-optic dysplasia (SOD) is a rare congenital disorder that may cause jaundice in infants. However, it is usually prone to neglect and misdiagnosis in infants with cholestasis because endocrine disorder such as panhypopituitarism is rare in the cause of infantile cholestasis. We report a case of SOD concurrent with acquired cytomegalovirus (CMV) infection, who presented with prolonged jaundice as the first clinical sign. PATIENT CONCERNS: The patient was a 2-month-old male infant who presented with cholestasis, combined with fever and panhypopituitarism...

RATIONALE: Primary malignant melanoma (MM) of the mediastinum is exceedingly rare; a review of the English-language literature reveals only a small number of case reports. In this paper, we discuss a case of primary mediastinal MM and present a review of the relevant literature on its clinical features and treatment. PATIENT CONCERNS: A 52-year-old male presenting with back pain was admitted to our hospital for treatment. Imaging examination revealed an anterior mediastinal mass and no evidence of other metastatic or primary lesions...

Chloroma refers to the extramedullary proliferation of immature myeloid precursors occurring in a gamut of myeloproliferative and myelodysplastic conditions; acute myeloid leukemia (AML), being the commonest. With nonspecific clinical and imaging manifestations, it runs a high risk of misdiagnosis which may significantly affect the outcome of an otherwise treatable lesion. Also with these lesions heralding impending blast crises, awareness of the imaging findings becomes imperative. Imaging not only helps raise the suspicion, but also guides further confirmation by demonstration of specific immunohistochemistry markers, ensuring timely institution of chemotherapy;...

BACKGROUND: Equine atypical myopathy (AM) is a toxic rhabdomyolysis associated with ingestion of hypoglycin A, derived typically in Europe, from Acer pseudoplatanus tree. Despite the wide distribution of this tree species in the UK, the number of cases reported annually varies, and there has been an apparent increase in prevalence in recent years. Although AM was first recognised in the UK, epidemiological studies have never been conducted focused solely on this country. OBJECTIVES: To describe the spatiotemporal distribution, presentation, treatment and outcome of AM cases reported in the UK...

We compared estimated costs of re-testing HIV-positive persons before ART initiation to the costs of ART provision to misdiagnosed HIV-negative persons. Savings from averted unnecessary ART costs were greater than re-testing costs within one year using assumptions representative of HIV testing performance in programmatic settings. Countries should implement re-testing before ART initiation.

The inflammatory and non-inflammatory disorders affecting the blood vessels are an important cause of death among patients. Additionally, some of the findings could be very subtle, while the consequences of misdiagnosis tragic. There is a limited number of factors by which the cutaneous blood vessels can be affected and the most common examples in the clinical practice will be discussed here: non-inflammatory purpuras; vascular-occlusive disorders; urticarias; vasculitides; and neutrophilic dermatoses.

As an important biological signal, electrocardiogram (ECG) signals provide a valuable basis for the clinical diagnosis and treatment of several diseases. However, its reference significance is based on the effective acquisition and correct recognition of ECG signals. In fact, this mV-level weak signal can be easily affected by various interferences caused by the power of magnetic field, patient respiratory motion or contraction, and so on from the sampling terminal to the receiving and display end. The overlapping interference affects the quality of ECG waveform, leading to the false detection and recognition of wave groups, and thus causing misdiagnosis or faulty treatment...

The schwannoma-like pleomorphic adenoma is a rare histopathological variant of the pleomorphic adenoma. Five previous reports with seven cases exist in English language literature. These tumors present in the parotid gland most commonly. Intraparotid schwannomas of the facial nerve and schwannomas with glandular differentiation have also been reported. A 60-year-old male presented with an asymptomatic swelling over the left angle of the mandible. The swelling had been present for about 12 years with a recent increase in size...

Reference intervals provide valuable information to medical practitioners in their interpretation of quantitative laboratory test results, and are critical in the assessment of patient health and in clinical decision-making. The reference interval serves as a health-associated benchmark with which to compare an individual test result. While the concept of reference intervals and their utility appear straightforward, the process of establishing accurate and reliable reference intervals is considerably complex and involved...

This study aimed to ascertain views, incidence of reporting and diagnostic criteria for gastric foveolar dysplasia. A questionnaire, a post-questionnaire discussion and microscopic assessment of selected cases was conducted by gastrointestinal pathologists to explore the above-stated aims. Fifty-four percent of respondents never or rarely diagnosed gastric foveolar-type dysplasia. The general consensus was that round nuclei, lack of nuclear stratification, presence of inflammation/damage and surface maturation favoured reactive change; while architectural abnormalities/complexity and nuclear enlargement mainly were used to separate low-grade from high-grade foveolar dysplasia...

BACKGROUND: Extranodal follicular dendritic cell sarcoma (FDCS) is a very rare malignancy with a variable clinical course. It is often not considered and has the potential to result in a misdiagnosis of other common sarcomas or sarcomatoid carcinomas. This is particularly true with the preoperative biopsy specimen, in which the tissue sample is often small. CASE PRESENTATION: A case of FDCS in a 63-year-old woman, arising in the urinary bladder, a previously unreported site, is described...

BACKGROUND: Dengue is a common cause of infection in adults in tropical countries. Sepsis is a syndrome of systemic manifestations induced by infection of any organisms; including bacterial, fungal and viral agents. Here, we investigated the diagnosis, management and outcomes of dengue patients presenting with sepsis in a prospective study of community-acquired sepsis in Thailand. METHODS: From June to December 2015, 874 adult patients (age≥18 years) with suspected or documented community-acquired infection, with ≥3 diagnostic criteria for sepsis according to the Surviving Sepsis Campaign 2012, and within 24 hours of admission were evaluated...

Traumatic or spontaneous hemarthroses are an important cause of joint effusions, and can complicate innate or acquired coagulopathies. The elbow is an unusual location for a spontaneous hemarthrosis; we describe a previously unreported case of warfarin-induced spontaneous elbow hemarthrosis, diagnosed by point-of-care ultrasound. On the basis of clinical and ultrasound findings arthrocentesis was deferred, and the patient was successfully treated with warfarin reversal and conservative care. Physical examination is unreliable for the detection of a joint effusion, and misdiagnosis and can lead to unnecessary investigation or resource use...

Breast cancer is the most prevalent cancer that affects women all over the world. Early detection and treatment of breast cancer could decline the mortality rate. Some issues such as technical reasons, which related to imaging quality and human error, increase misdiagnosis of breast cancer by radiologists. Computer-aided detection systems (CADs) are developed to overcome these restrictions and have been studied in many imaging modalities for breast cancer detection in recent years. The CAD systems improve radiologists' performance in finding and discriminating between the normal and abnormal tissues...

OBJECTIVE: The diagnosis and management of patients with idiopathic intracranial hypertension (IIH) frequently relies on lumbar puncture to ascertain intracranial pressures. However, pressures derived this way may be spurious due to patient body habitus and behavior. We recently incorporated direct continuous intracranial pressure (ICP) monitoring into the work-up for IIH and review our experience and outcomes. METHODS: Through billing records, we identified all patients during a 3-year period who had a diagnosis of idiopathic intracranial hypertension and who underwent ICP monitoring prior to shunt placement or revision...

BACKGROUND: Fractures of the proximal femur constitute a major public health problem, with an annual incidence in Spain of 7.6 cases per 1000 inhabitants over 65 years of age. Hip fractures are frequent in elderly patients, related to osteoporosis and with low energy trauma, which means that they can be considered a geriatric syndrome. Simultaneous ipsilateral extra- and intra-articular hip fractures are considered as very rare are, and generally speaking, classified as extra- or intra-capsular fractures...

Wilson disease (WD) is a neurodegenerative disorder, which presents as a spectrum of neurologic manifestations that includes tremor, bradykinesia, rigidity, dystonia, chorea, dysarthria, and dysphagia, together with a combination of neurologic symptoms that can easily lead to misdiagnosis. An early diagnosis of WD, and appropriate anticopper treatment, usually leads to a marked improvement in patient health. Conversely, delayed diagnosis can result in persistent pathology, which, left untreated, can ultimately prove lethal...
