REVIEW
Hao Deng, Heng Xiao
Hailey-Hailey disease (HHD) is a rare autosomal dominant acantholytic dermatosis, characterized by a chronic course of repeated and exacerbated skin lesions in friction regions. The pathogenic gene of HHD was reported to be the ATPase calcium-transporting type 2C member 1 gene (ATP2C1) located on chromosome 3q21-q24. Its function is to maintain normal intracellular concentrations of Ca(2+)/Mn(2+) by transporting Ca(2+)/Mn(2+) into the Golgi apparatus. ATP2C1 gene mutations are reportedly responsible for abnormal cytosolic Ca(2+)/Mn(2+) levels and the clinical manifestations of HHD...

REVIEW
Jon Rosenberg, Benjamin T Galen
PURPOSE OF REVIEW: Recurrent meningitis is a rare clinical scenario that can be self-limiting or life threatening depending on the underlying etiology. This review describes the causes, risk factors, treatment, and prognosis for recurrent meningitis. As a general overview of a broad topic, the aim of this review is to provide clinicians with a comprehensive differential diagnosis to aide in the evaluation and management of a patient with recurrent meningitis. RECENT FINDINGS: New developments related to understanding the pathophysiology of recurrent meningitis are as scarce as studies evaluating the treatment and prevention of this rare disorder...

REVIEW
Simon Vulfsons, Negev Bar, Elon Eisenberg
PURPOSE OF REVIEW: The clinical diagnostic dilemma of low back pain that is associated with lower limb pain is very common. In relation to back pain that radiates to the leg, the International Association for the Study of Pain (IASP) states: "Pain in the lower limb should be described specifically as either referred pain or radicular pain. In cases of doubt no implication should be made and the pain should be described as pain in the lower limb." RECENT FINDINGS: Bogduks' editorial in the journal PAIN (2009) helps us to differentiate and define the terms somatic referred pain, radicular pain, and radiculopathy...

Meckel's diverticulum is a vestigial remnant of the omphalomesenteric duct. It is the most frequent defect of the gastrointestinal tract and is present in approx. 2% of the population: more often in boys than in girls, at a 3:1 ratio. Meckel's diverticulum causes clinical symptoms only in 4-6% of individuals. It is situated approximately 60-100 cm away from the Bauhin's valve. The wall of Meckel's diverticulum consists of all layers typical of the small intestine. It is usually approx. 2-3 cm long, but it can reach lengths of over 10 centimetres...

18FDG PET-CT is useful for early and differential diagnosis of dementia. ASL-MRI seems an attractive alternative. Visual agreement was calculated in 21 brain regions bilaterally in 9/11 patients with suspected early-stage dementia, excluding 2 patients due to ASL-MRI motion artefacts. Overall gross agreement was almost perfect and identical between and within modalities (κ=0.85-0.86, p<0.05). Intermodality regional agreement was variable, moderate (κ=0,56 in posterior cingulate) to perfect (including in precuneus), not different from intramodality agreement...

Anaplastic lymphoma kinase (ALK) positive diffuse large B-cell lymphoma (ALK+DLBCL) is a rare, distinct and aggressive subtype of non-Hodgkin's lymphoma (NHL). These tumors are considered to be derived from post-germinal center B cells but peculiarly their distinction is based on the fact that they are ALK-positive neoplastic B cells but lack expression of B cell markers (CD19,CD20, CD79a), T cell markers (CD3, CD5) and CD30. Its broad differential diagnosis and similarities to plasmablastic lymphoma, immunoblastic DLBCL, Anaplastic large-cell lymphoma (ALCL) of T-null cell lineage, and poorly differentiated/anaplastic carcinoma pose a grave challenge to physicians with conventional costly treatment for DLBCL failing to yield any clinical or prognostic significance in ALK+DLBCL...

BACKGROUND: It is a great challenge for pathologists to initially diagnose metastatic malignant mesothelioma (MM) by the lymph node biopsy without any history of primary MM. Because the onset of MM is hidden and the metastatic MM in lymph node is relatively uncommon. Besides, morphologic and immuohistochemistry features of MM are similar to other tumors. METHODS: In order to improve the initial diagnostic accuracy of metastatic MM from LN biopsy and to reduce or avoid the possibility of missed diagnosis or misdiagnosis, we had collected the clinical and pathological data of the metastatic MM cases in our department, and summarized the characteristics of morphological, immunohistochemical and fluorescence in situ hybridization (FISH) results...

Dedifferentiated chondrosarcoma is defined by the presence of a low grade malignant cartilaginous component juxtaposed to a high grade malignant non-cartilaginous sarcomatous components. Only 4 cases in which the high grade component showed epithelial differentiation have been reported in the literature; three featured a squamous and the one a glandular epithelial component. Here we describe a case of dedifferentiated chondrosarcoma exhibiting epithelial "adamantinoma-like" basaloid features. The patient underwent wide resection of the proximal tibia and post-operative chemotherapy and died 8 months after the diagnosis due to lung and bone metastases...

Stroke mimics (SM) are non-vascular conditions that present with an acute neurological deficit simulating acute ischemic stroke and represent a significant percentage of all acute stroke hospital admissions. The most common clinical SM includes conversion/functional (psychiatric disorder); seizures and postictal paralysis; toxic-metabolic disturbances; brain tumours; infections, and migraine. Imaging is essential for SM recognition, being Diffusion weighted imaging (DWI), perfusion imaging and angiographic studies very useful...

INTRODUCTION: Hyponatremia is the most common type of electrolyte imbalance, occurring when serum sodium is below threshold levels, typically 135mmol/L. Electrolyte balance has been identified as one of the most challenging subjects for medical students, but also as one of the most relevant areas to learn about according to physicians and researchers. We present a computer-interpretable guideline (CIG) model that will be used for medical training to learn how to improve the diagnosis of hyponatremia applying an expert consensus document (ECDs)...

The aim of this work is to review the spectrum of sinonasal lesions that extend to the endocranium and to present key points that may narrow the differential diagnosis. The most frequent sinonasal lesions that extend into the endocranium are malignant; however, benign entities are not unusual. Imaging diagnosis is difficult because malignant lesions and benign entities share similar clinical, epidemiologic, and imaging features. Tumor features in relation to bone, intratumor homogeneity and structure, magnetic resonance imaging signal, along with clinical and epidemiologic aspects may allow an appropriate diagnostic focus with important management implications...
