In this study we report an uncommon endoscopic endonasal image of an atrophic optic nerve as seen after surgical removal of a suprasellar meningioma. The peculiarity of this case is the long-lasting underestimated ocular symptomatology of the patient who reported a 15-year history of impairment of vision on her left eye. After making serendipitously the diagnosis of a suprasellar mass, an endoscopic endonasal surgery was performed and, at the end of tumor removal, the impressive left optic nerve atrophy due to enduring local compression was visualized...

As health technologies are slowly adapted in low resource settings, the support modalities, equipment and supplies that allow these advances to be implemented are often not fully considered. It is not uncommon to install a new computed tomography scan machine in a hospital in sub-Saharan Africa only to suffer extensive downtime from unreliable electricity supply or unavailability of contrast agents (Essential Health Technologies WHO 2011). Countless expensive high-tech devices sit idle in low resource settings for lack of proper disposables and properly trained health care professionals...

Although small prior studies have suggested that IgE can be low in common variable immunodeficiency (CVID), the workup for patients with recurrent infections and suspected hypogammaglobulinemia does not include the routine measurement of serum IgE. We sought to test the hypothesis that low/undetectable serum IgE is characteristic of CVID by comparing the frequency of low/undetectable serum IgE in healthy controls and patients with CVID. We measured total serum IgE in a large multi-center cohort of patients with CVID (n = 354) and compared this to large population-based cohorts of children and adults...

Acute rhinosinusitis is an important health problem. Even though its frequency is not well documented in our country?, the economic burden it bears is not insignificant as it notably alters the quality of life of affected patients. Its diagnosis is generally clinical in nature, with further studies reserved only for the differential diagnoses of complications or tumour-like processes. The most frequent causes are viral infections, although Streptococcus pneumoniae and Haemophilus influenzae are the most commonly isolated bacterial agents...

BACKGROUND: Medication errors are not uncommon in hospitalized patients. Paediatric patients may have increased risk for medication errors related to complexity of weight-based dosing calculations or problems with drug preparation and dilution. This study aimed to determine the incidence of medication errors in paediatric anaesthesia in a university paediatric hospital, and to identify their characteristics and potential predictive factors. METHODS: This prospective incident monitoring study was conducted between November 2015 and January 2016 in an exclusively paediatric surgical centre...

BACKGROUND: Lingual hematoma (LH) is a relatively uncommon entity seen after both medical and traumatic etiologies. Regardless of the cause, the feared complication is acute airway obstruction. CASE REPORT: Our case involves a 39-year-old man who presented to the Emergency Department via emergency medical services with an enlarging LH after an unwitnessed fall, suspected to be an alcohol withdrawal seizure. The bleeding was likely exacerbated by previously undiagnosed thrombocytopenia...

Fever of unknown origin (FUO) is commonly defined as fever higher than 38.3°C on several occasions during at least 3 weeks with uncertain diagnosis after a number of obligatory investigations. The differential diagnosis of FUO can be subdivided in four categories: infections, malignancies, noninfectious inflammatory diseases, and miscellaneous causes. In most cases of FUO, there is an uncommon presentation of a common disease. FDG-PET/CT is a sensitive diagnostic technique for the evaluation of FUO by facilitating anatomical localization of focally increased FDG uptake, thereby guiding further diagnostic tests to achieve a final diagnosis...

BACKGROUND: Flap congestion is a frequently described intraoperative complication during autologous breast reconstruction with abdominal perforator flaps, which, if not addressed, can lead to detrimental results such as flap failure. Here, we describe our institution's algorithm of intraoperative salvage of congested flaps and present their outcomes. METHODS: All patient charts from 2002 to 2016 of a single plastic surgeon were reviewed for patients who underwent deep inferior epigastric perforator flap breast reconstruction resulting in 602 patients and 831 flaps...

Premature Ventricular Contraction (PVC)/ventricular tachycardia (VT) with left bundle branch block (LBBB) morphology and inferior axis has been described classically to originate from the right ventricular outflow tract (RVOT). Some uncommon sites of idiopathic ventricular arrhythmia (VA) origins have been revealed including tricuspid annulus (TA) and right ventricular (RV) inflow free wall region. We present a series of two cases who have undergone electrophysiological study and successful radiofrequency ablation of frequent monomorphic PVCs with LBBB pattern originating from relatively uncommon sites of RV - TA and RV inflow free wall region...

Lisfranc injuries are relatively uncommon. No specific incidence of subtle injuries has been reported; however, almost one-third are missed on initial review. These missed injuries are a common cause of litigation. Although seen in high-energy injuries with direct application of forces, they are also associated with lower-energy indirect mechanisms, often on the athletic field. This article provides a topical review of subtle Lisfranc disruptions, focusing on contemporary perspectives, and describes a modification to the most prevalent classification system...

Humans can seamlessly infer other people's preferences, based on what they do. Broadly, two types of accounts have been proposed to explain different aspects of this ability. The first account focuses on spatial information: Agents' efficient navigation in space reveals what they like. The second account focuses on statistical information: Uncommon choices reveal stronger preferences. Together, these two lines of research suggest that we have two distinct capacities for inferring preferences. Here we propose that this is not the case, and that spatial-based and statistical-based preference inferences can be explained by the assumption that agents are efficient alone...

Background Macrophage activation syndrome (MAS) is an uncommon but serious complication of systemic lupus erythematosus (SLE). We aimed to identify factors associated with MAS among adult hospitalized SLE patients. Methods Within the Brigham and Women's Hospital (BWH) Lupus Center Registry, we identified adult SLE patients > age 17 who had been hospitalized from 1970 to 2016, with either ferritin > 5000 ng/ml during admission or "macrophage activation syndrome" or "MAS" in discharge summary...

Ovarian smooth muscle tumours are rare. Notable myxoid change in smooth muscle tumours is uncommon, and raises diagnostic issues that need to be considered on evaluating a spindle cell lesion with notable myxoid change. There is only one case of myxoid leiomyoma of the ovary previously reported. We here report a case of ovarian leiomyoma with areas of myxoid stroma and discuss the relevant differential diagnosis and histological features to be assessed in such a lesion.

Malignancies of the parotid gland are relatively uncommon, accounting for only 3-6% of all head and neck cancers. Most of them are primary neoplasms, metastases are uncommon. Renal cell carcinoma (RCC) represents 3% of adult malignancies, the clear cell type comprises up to 70% of all RCC. RCC has an unpredictable behavior and the unique potential to metastasize to nearly every organ in the body. Though not as frequent, metastatic RCC to the head and neck has been identified in the thyroid, salivary glands, skull base, sinuses, pharynx, tonsils, tongue, lip and skin...

Magnesium is the second most abundant intracellular cation. Deficiency can cause several neurological complications, including cerebellar syndromes, with various MRI findings. These include cerebellar oedema, presumably through a similar mechanism to that in posterior reversible encephalopathy syndrome (PRES). People particularly vulnerable to deficiency include those with high alcohol consumption, excessive loss due to gastrointestinal pathology and those taking certain medications, including proton pump inhibitors...

OBJECTIVE: In view of low prevalence rates, diabetes is discussed as a protective factor for the occurrence of Takotsubo syndrome (TTS). Furthermore, it was associated with improved outcome in a small single-center analysis. Therefore, this study assessed the prevalence and prognostic relevance of concomitant diabetes in TTS. RESEARCH DESIGN AND METHODS: A total of 826 patients with TTS were enrolled in an international, multicenter, registry-based study (eight centers in Italy and Germany)...

Plexiform neurofibroma (PNF) is a rare variant of neurofibromatosis type1 (NF-1), which histopathologically, is a subtype of benign nerve sheath tumors, neurofibromas (NF). It develops as a result of proliferation in all parts of peripheral nervous system and can cause the functional damage, deformities, pain, considerable mortality, and morbidity and even the increasing risk of malignant transformation in some critical cases. Currently, the surgical intervention is the treatment of choice for PNF patients, which due to the tumor invasion, massive growth, and the chance of postoperative regrowth is not possible...
