Massive ovarian oedema is a rare non-neoplastic clinicopathologic entity has a higher incidence in women during their second and third life decade. The oedema can be presented in one or both ovaries as a result of partial intermittent torsion of the ovarian pedicle that interferes to the venal and lymphatic drainage of the ovary. We present a clinical case of a 16 year old with massive ovarian oedema and we performed a review of the literature. The pathophysiology of this entity is very complex. We tried to perform a complete review of the literature and focus on the complexity of this entity as far as its pathophysiological backround is concerned and as far as its clinical presentation is concerned. In conclusion, massive ovarian oedema is a rare, multi disease mimicking clinical entity, with an acute or progressive clinical presentation. It has also to be a part of our differential diagnosis in cases of acute abdominal pain and we have to try to treat her conservatively, in order to preserve fertility.
An unusual case of primary spontaneous tension pneumothorax in a jamaican female.
Johnson, M; French, S; Cornwall, D
2014-06-01
Spontaneous pneumothorax is a well-recognized entity with a classical presentation of acute onset chest pain and shortness of breath. It may be complicated by the development of a tension pneumothorax or a haemopneumothorax. We report an interesting case of a spontaneous tension haemopneumothorax which presented atypically and was diagnosed on computed tomography (CT) scan of the chest. The clinical and pathophysiological characteristics and treatment of this unusual entity is discussed.

Turel, Mazda K; Wewel, Joshua T; Kerolus, Mena G; O'Toole, John E
2017-01-01
Idiopathic spinal cord herniation is a rare and often missed cause of thoracic myelopathy. The clinical presentation and radiological appearance is inconsistent and commonly confused with a dorsal arachnoid cyst and often is a misdiagnosed entity. While ventral spinal cord herniation through a dural defect has been previously described, intravertebral herniation is a distinct entity and extremely rare. We present the case of a 70-year old man with idiopathic thoracic transdural intravertebral spinal cord herniation and discuss the clinico-radiological presentation, pathophysiology and operative management along with a review the literature of this unusual entity.

In daily police practice, forensic investigation of criminal cases is mainly based on manual work and the experience of individual forensic experts, using basic storage and data processing technologies. However, an individual criminal case does not only consist of the actual offence, but also of a variety of different aspects involved. For example, in order to solve a financial criminal case, an investigator has to find interrelations between different case entities as well as to other cases. The required information about these different entities is often stored in various databases and mostly requires to be manually requested and processed by forensic investigators. We propose the application of semantic technologies to the domain of forensic investigations at the example of financial crimes. Such combination allows for modelling specific case entities and their interrelations within and between cases. As a result, an explorative search of connections between case entities in the scope of an investigation as well as an automated derivation of conclusions from an established fact base is enabled. The proposed model is presented in the form of a crime field ontology, based on different types of knowledge obtained from three individual sources: open source intelligence, forensic investigators and captive interviews of detained criminals. The modelled crime field ontology is illustrated at two examples using the well known crime type of explosive attack on ATM and the potentially upcoming crime type data theft by NFC crowd skimming. Of these criminal modi operandi, anonymized fictional are modelled, visualized and exploratively searched. Modelled case entities include modi operandi, events, actors, resources, exploited weaknesses as well as flows of money, data and know how. The potential exploration of interrelations between the different case entities of such examples is illustrated in the scope of a fictitious investigation, highlighting the potential of the approach.
Gastric Volvulus: A Rare Entity Case Report and Literature Review
Akhtar, Aisha; Sheikh, Abdul Ahad E; Sheikh, Abu Baker; Perisetti, Abhilash
2018-01-01
Gastric volvulus is a rare entity defined as an abnormal rotation of the stomach around itself. It is a diagnosis of exclusion; the clinical index of suspicion is always low and is mostly diagnosed on imaging or on the surgery table. When it occurs, it is an emergency due to the risk of strangulation and consequent gangrene of the stomach. Mesentero-axial (MA) gastric volvuli constitute one-third of all cases. Here, we are present an interesting case of acute MA gastric volvulus diagnosed with imaging and treated subsequently. PMID:29755908

Nontraumatic spinal cord injury from surfing is a new entity first described in 2004 and likely of ischemic etiology. We report the case of a 25-year-old man who presented to the emergency department with a 2-week history of lower extremity weakness after surfing in Indonesia. The patient reported developing low back pain, lower extremity weakness, sensory changes, and urinary retention shortly after his first surfing lesson. The patient was subsequently diagnosed with surfer's myelopathy. The purpose of this report is to review the clinical presentation, etiology, risk factors, and management of this increasingly described entity.

Primary effusion lymphoma (PEL) or body cavity lymphoma is a rare type of extra nodal lymphoma of B-cell origin that presents as lymphomatous effusion(s) without any nodal enlargement or tumor masses. It belongs to the group of AIDS related non-Hodgkin's lymphomas. First described in 1996 in HIV infected individuals who were coinfected with Kaposi's sarcoma-associated herpesvirus (KSHV) or HHV-8 virus, it was included as a separate entity in WHO classification of tumors of hematopoietic and lymphoid tissue in the year 2001. The definition included association with HHV-8 virus as a mandatory diagnostic criterion. However, cases were later reported where PEL-like disease process was diagnosed in HHV-8 negative patients. This was eventually recognized as a rare but distinct entity termed as “HHV-8-unrelated PEL-like lymphoma”. Herein, we are reporting a case of an elderly patient who presented with a large pleuropericardial effusion and was eventually diagnosed with this entity. Till date, only around 50 cases of HHV-8-unrelated PEL-like lymphoma have been reported and our case being EBV, HIV, and Hepatitis C negative makes it very unique and rare occurrence. We are also presenting a review of relevant literature focused mainly on comparing outcomes in patients treated with and without chemotherapy. PMID:24716045

A typical male looking adolescent with a legal female gender assignment presented with haematuria. Investigations led to the diagnosis of Persistent Mullerian Duct Syndrome. The condition is indeed a rare entity that needs a multidisciplinar team management. Case hypothesis: A case of Persistent Mullerian Duct Syndrome undiagnosed at birth because karyotyping was defaulted, thus resulting in a significant impact on the legal gender assignment and psychosocial aspects. Promising future implications: The reporting of this case is important to create awareness due to its rarity coupled with the rare presentation with hematuria as a possible masquerade to menstruation. There were not only medical implications, but also psychosocial and legal connotations requiring a holistic multidisciplinary management. Copyright® by the International Brazilian Journal of Urology.
An Exploration of Trainer Filtering Approaches

Simutator operators face a twofold entity management problem during Live-Virtual-Constructive (LVC) training events. They first must filter potentially hundreds of thousands of simulation entities in order 10 determine which elements are necessary for optimal trainee comprehension. Secondarily, they must manage the number of entities entering the simulation from those present in the object model in order to limit the computational burden on the simulation system and prevent unnecessary entities from entering the simulation, This paper focuses on the first filtering stage and describes a novel approach to entity filtering undertaken to maximize trainee awareness and learning. The feasibility of this novel approach is demonstrated on a case study and limitations to the proposed approach and future work are discussed.

Primary breast tuberculosis manifested as abscess is a rare entity. We are reporting a case of primary breast tuberculosis, which presented as breast abscess. Abscess was drained and tissue sent for histopathology. To our surprise, diagnosis came as breast tuberculosis. Aspiration cytology was not done, as it is not a routine test for abscess cases. Patient was put on anti- tubercular drugs. In the follow-up of 6 months, she was asymptomatic and advised to continue medicine.

The dorsal patellar defect is a relatively rare entity that involves the superolateral quadrant of the patella. It is usually considered to represent a delayed ossification process, although its exact origin remains unclear. Because of its usually innocuous nature and clinical course, invasive interventions are generally deemed unnecessary, although curretage has been successfully performed on symptomatic cases. This case report presents a rather unusual case of symptomatic bilateral dorsal patellar defects with cartilage involvement and widespread surrounding bone marrow edema as demonstrated by magnetic resonance imaging (MRI). Both cartilage involvement and bone marrow edema should be considered part of the spectrum of associated MRI findings that can be encountered in this entity. Furthermore, the presented case shows that symptomatic dorsal patellar defects can be treated conservatively with success and that (decrease of) pain symptoms are likely related to (decrease of) bone marrow edema.

INTRODUCTION Appendiceal diverticulosis is a rare entity, with a global incidence between 0.004% and 2.1% of all appendectomies. It has been related with an elevated risk of perforation in comparison to acute appendicitis, as well as an increased risk for synchronic appendicular cancer in 48% of the cases, and colonic cancer in 43%. The incidence of chronic appendicitis has been reported in 1.5% of all appendicitis cases. PRESENTATION OF CASE We present a 73-year-old female, with no relevant familial history, who presented due to a four-month-long oppressive, moderate pain in the lower right abdominal quadrant without irradiation or any other accompanying symptoms. DISCUSSION The documented incidence of appendiceal diverticula and chronic appendicitis by themselves is low; therefore the presence of both entities at the same time is extremely rare. CONCLUSION We present a case in which both diagnoses concurred in the same patient. The relevance of this case relies on the importance of the adequate knowledge of these pathologies, so we can approach them correctly. Although it does not represent an absolute surgical emergency, appendectomy represents the first therapeutic option. PMID:25460447

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare but well-reported clinical entity. It is classically described as symmetrical involvement of both upper extremities. Asymmetrical involvement had also been reported, but unilateral presentation is very rare. We hereby report a case of unilateral RS3PE in a patient of seronegative rheumatoid arthritis which was initially misdiagnosed as cellulitis and was given high dose antibiotics without any significant improvement. Later a rheumatologic consultation leads to a prompt diagnosis, and treatment with steroids leads to dramatic reversal of symptoms. This case demonstrates the rare presentation of this rare clinical entity and highlights the necessity of awareness regarding unilateral disease to clinicians.

Primary breast lymphoma (PBL) is a rare entity accounting for less than 1% of all breast malignancies. Diagnostic criteria for primary Hodgkin's lymphoma of the breast are: the presence of sufficient tissue for diagnosis, close interaction between mammary tissue and lymphomatous infiltrate and no evidence or prior diagnosis of widespread lymphoma. Our case illustrates an unusual presentation of Hodgkin's lymphoma of the breast: clinically as inflammatory breast cancer and core biopsy as granulomatous mastitis, the final diagnosis requiring surgical biopsy. Current information regarding this entity is scant, mainly build upon its rarity. In this paper we assess the clinical presentation, the step-by-step diagnosis, the treatment and the importance of immunohistochemistry in this uncommon condition. PMID:26225149

[Epithelioid hemangioendothelioma: an uncommon liver tumor].
Pareja, Eugenia; Cortés, Miriam; Rayon, Miguel; Moya, Angel; Mir, Jose
2010-01-01
We report the case of a female patient who was referred to our unit because of a solid liver tumor, suggestive of metastasis. After biopsy, the patient was diagnosed with epithelioid hemangioendothelioma of the liver. Epithelioid hemangioendothelioma is a rare entity with an unpredictable, potentially fatal, clinical course and outcome. Due to its rarity, this entity should be considered when a solitary hepatic lesion is detected and should be included in the differential diagnosis with liver metastases. We highlight the infrequency of this tumor, its presentation as a solitary hepatic lesion and the indication of surgical treatment. We describe the clinical and pathological characteristics of epithelioid hemangioendothelioma of the liver and report a new case of this entity. The distinct therapeutic options are discussed.

Lung cancer is the most common cancer worldwide. On imaging, it typically presents as mass or nodule. Recognition of these typical cases is often straightforward, whereas diagnosis of uncommon manifestations of primary lung cancer is far more challenging. Lung cancer can mimic a variety of benign entities, including pneumonia, lung abscess, postinfectious scarring, atelectasis, a mediastinal mass, emphysema and granulomatous diseases. Correlation with previous history, clinical and biochemical parameters is necessary in the assessment of these cases, but often aspecific and inconclusive. Whereas 18 F-fluorodeoxyglucose ( 18 F-FDG) Positron Emission Tomography is the cornerstone in staging of lung cancer, its role in diagnosis of these uncommon manifestations is less straightforward since benign entities can present with increased 18 F-FDG-uptake and, on the other hand, a number of these uncommon lung cancer manifestations do not exhibit increased uptake. Chest Computed Tomography (CT) is the imaging modality of choice for both lesion detection and characterization. In this pictorial review we present the wide imaging spectrum of CT-findings as well as radiologic-pathologic correlation of these uncommon lung cancer manifestations. Knowledge of the many faces of lung cancer is crucial for early diagnosis and subsequent treatment. A multidisciplinary approach in these cases is mandatory. Copyright © 2017 Elsevier B.V.

Isotretinoin is the most effective drug in the treatment of severe recalcitrant nodulocystic acne. However, treatment with this drug is associated with adverse effects, the most severe being teratogenesis. It has been estimated that 40% of pregnancies exposed to isotretinoin present spontaneous abortion and 35% develop embryopathy. We present the case of a newborn with a history of prenatal exposure to isotretinoin, a clinical entity that can be avoided, with severe congenital defects in the central nervous system and important facial dysmorphisms, with unfavorable clinical course.

[Choledocal cyst: analysis of 29 cases and review or the literature].
Vila-Carbó, J J; Ayuso, L; Hernández, E; Lluna, J; Ibáñez, V
2006-01-01
The aim of the present study has been to systematize the clinical presentation of the entity named choledochal cyst, in relation with its probable etiopathology and the intraoperative findings as well as its evolution after surgery, based on the revision of the literature and of our experience in 29 cases. 29 cases of cystic dilatation of the biliar duct extra and/or intrahepatic are analyzed. In 4 cases the diagnosis was prenatal and two were excluded of the study after it has been confirmed they suffered biliary atresia type I. In the left 27 cases, 19 variables are analyzed retrospectively, like age, sex, weight, symptoms, ultrasonographic images, etc. Subsequently, intra-operative cholangiographic findings were correlated with the clinic presentation and the evolution of the patients after surgery. Of the 27 cases analyzed 16 (59,25%) were cystic dilatations from which 14 had a neonatal or early clinic presentation (before 2 years), however the fusiform dilatations were presented later on. From the analyzed symptoms, in relation with the age only the pain and the jaundice showed significant differences, being the pain most frequent in later presentation ande the jaundice in the early form. The two cases of type 3 of Todani or choledochocele were of later presentation. An anomaly in the bilionpacreatric junction was detected in 15 patients; the majority had a later presentation, associated to pancreatitis in 4 cases. Primary cyst excision and biliary Roux-en-Y reconstruction was the treatment of election in the majority of cases. In 3 cases we used the appendix to replace the choledocus, but all three cases were reconverted two years later because of permanent elevation of ALT and GGT. In favour of the literature and of our experience nowadays it would be possible to systematize this malformation and make a division in two groups, depending on the cholangiographic findings and clinical presentation: 1. Cystic dilatations with a clinical neonatal presentation or beneath 2 years. 2. Fusiform dilatations with a later clinical predominance and associated frequently to pancreatitis and anomalous pancreatobiliary junction. Choledochocele is an entity that must be considered not only for its etiology but for its clinical presentation and treatment. Primary cyst excision and biliary Roux-en-Y reconstruction is the treatment of election. Regular long-term review of these patients is mandatory in the surveillance of sub-clinic cholangitis and the risk of possible long-term malignance of this entity.
Streptococcal toxic shock syndrome after breast reconstruction.
Agerson, Ashley N; Wilkins, Edwin G
2005-05-01
Streptococcal toxic shock syndrome (STSS) is an increasingly common disease entity but has rarely been described in the plastic surgery literature. We present the first known case of STSS associated with a reconstructive procedure. Two weeks postoperatively from a transverse rectus abdominis musculocutaneous flap for breast reconstruction, our patient presented with flulike symptoms and progressed rapidly to multiorgan failure. Though initially no nidus for infection was evident, the abdominal donor site was surgically debrided and found to contain group A Streptococcus. Following aggressive rehydration and antibiotic therapy, the patient gradually made a full recovery. In this case report, we review the presentation and epidemiology of STSS and compare it to the more common staphylococcal toxic shock syndrome. In addition, we discuss the management and outcomes of STSS, with an emphasis on raising clinical suspicion for this rare but dangerous entity.

Stabbing Yourself in the Heart: A Case of Autoimmunity Gone Awry
Vigneswaran, Hari; Parikh, Leslie; Poppas, Athena
2015-01-01
Within internal medicine, cardiac and neurologic pathology comprises a vast majority of patient complaints. Physicians and advanced-care practitioners must be highly educated and comfortable in the evaluation, diagnosis, and management of these entities. Chest pain accounts for millions of annual visits to the emergency room with pericarditis diagnosed in approximately four percent of patients with nonischemic chest pain. Guillain-Barre Syndrome is autoimmune polyneuropathy that often results in transient paralysis. Simultaneous diagnosis of both entities is a rare but described phenomenon. Here, we present a clinical case of GBS associated pericarditis. A fifty-five-year-old man with history of renal transplant presented with lower extremity weakness and urinary incontinence. Physical exam and diagnostic studies confirmed Guillain-Barre Syndrome. Patient subsequently developed stabbing chest pain with clinical presentation and electrocardiogram consistent with pericarditis. The patient was successfully treated for both diseases. This case highlights that although infrequent, internal medicine care providers must be cognizant of this correlation to ensure timely diagnosis and treatment. PMID:26664359
Tuberculosis-associated Fibrosing Mediastinitis: Case Report and Literature Review.
Tan, Ronald; Martires, Joanne; Kamangar, Nader
2016-01-01
Fibrosing mediastinitis is a rare condition defined by the presence of fibrotic mediastinal infiltrates that obliterate normal fat planes. It is a late complication of a previous granulomatous infection, such as histoplasmosis or tuberculosis (TB). Due to its rarity, fibrosing mediastinitis is often under-recognized, and the clinical presentation is variable and dependent on the extent of infiltration or encasement of structures within the mediastinum. We present a case of fibrosing mediastinitis in a man with a prior history of TB, who presented with progressive dyspnea and was found to have chronic mediastinal soft tissue opacities and pulmonary hypertension. His diagnosis was delayed due to the lack of recognition of this clinical/radiographic entity. Fibrosing mediastinitis is a rare entity usually caused by granulomatous disease. Most cases develop as a late complication of histoplasmosis or TB. The presence of calcified mediastinal soft tissue infiltrates on advanced chest imaging can be diagnostic of fibrosing mediastinitis in patients with a prior history of a granulomatous infection once active processes such as malignancy are excluded.
Giant hydronephrosis in a case of ureterocele with duplex system: an entity yet not reported.

2017-08-10
Ureterocele, which is a cystic dilatation of the terminal ureter, is usually associated with the upper moiety in a case of the duplex system. Giant hydronephrosis, a rare entity, is usually due to pelviureteric junction obstruction and is usually diagnosed in infants and children. We report a unique case of a unilateral complete duplex system with ureterocele with giant hydronephrosis of the upper moiety in an adult woman presenting as an abdominal lump. To the best of our knowledge, this is the first case of giant hydronephrosis associated with ureterocele in an adult patient. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Primary disorders of the lymphatic vessels--a unified concept.
Levine, C
1989-03-01
Congenital defects of lymphatics constitute a spectrum of disorders that may manifest with a variety of clinical presentations including lymphedema, chylous effusions, lymphangiomatous malformations with cystic masses and localized gigantism, and intestinal lymphangiectasia with malabsorption. These entities constitute a relatively rare group of disorders, the origin of which remains somewhat controversial, but in some it appears to be due to early lymphatic obstruction. Five cases are described, which demonstrate the anatomical pathology of these entities. A classification and description of the defects is also presented. An attempt is made to present a unified theory of origin for this seemingly diverse group of diseases. While these entities may be challenging from a diagnostic and therapeutic standpoint, a wide variety of imaging modalities, which includes lymphography, computed tomography scanning, and ultrasound, may be used to diagnose the extent and internal structural characteristics of the abnormalities.
A case of penile fracture at the crura of the penis without urethral involvement: Rare entity.
Srinivas, B V; Vasan, S S; Mohammed, Sajid
2012-07-01
Penile fracture is a rare injury, most commonly sustained during sexual intercourse. We report the case of a 29-year-old man who presented with bilateral rupture of the crura of the cavernosa without urethral injury. This is the first case in the literature to present with this unique finding. Urgent surgical exploration was performed and the injuries repaired primarily. At follow-up, the patient reported satisfactory erectile function. This case highlights the importance of early diagnosis with unusual presentation and early surgical repair for better outcome.
Idiopathic Subareolar Breast Abscess in a Male Patient
Ranga, Upasana; Veeraiyan, Saveetha
2015-01-01
We present a case of left breast abscess in a young male patient who presented with acute onset swelling left breast. Imaging studies helped in accurate diagnosis and the case was managed by subareolar incision and drainage. Subareolar breast abscess is an uncommon entity in male and should be kept as a differential diagnosis for male breast swellings. PMID:25738061
Lingual Thyroid Carcinoma: A Case Report and Review of Surgical Approaches in the Literature.
Stokes, William; Interval, Eric; Patel, Rusha
2018-07-01
Lingual thyroid cancer is a rare entity with a paucity of literature guiding methods of surgical treatment. Its location presents anatomic challenges with access and excision. We present a case of T4aN1b classical variant papillary thyroid carcinoma of the lingual thyroid that was removed without pharyngeal entry. We also present a review of the literature of this rare entity and propose a treatment algorithm to provide safe and oncologic outcomes. Our review of the literature found 28 case reports of lingual thyroid carcinoma that met search criteria. The trans-cervical/trans-hyoid approach was the most frequently used and provides safe oncologic outcomes. This was followed by the transoral approach and then lateral pharyngotomy. Complications reported across the series include 1 case of pharyngocutaneous fistula associated with mandibulotomy and postoperative respiratory distress requiring reintubation or emergent tracheostomy in 2 patients. The location of lingual thyroid carcinoma can be variable, and surgical management requires knowledge of adjacent involved structures to decrease the risk of dysphagia and airway compromise. In particular, for cases where there is extensive loss to swallowing mechanisms, laryngeal suspension can allow the patient to resume a normal diet after treatment.
Dermoid cyst of the pancreas: A case report with literature review
Lane, Jason; Vance, Ansar; Finelli, Daniel; Williams, Gary; Ravichandran, Pars
2012-01-01
Pancreatic dermoid cysts represent a rare entity with 35 cases described in the world literature, including the present one. Pre-operative diagnosis is difficult, with definitive diagnosis usually taking place intra-operatively. We report the case of a 63 year old male with a symptomatic, 6 cm cystic mass in the body of the pancreas. The pre-operative evaluation suggested a cystic neoplasm, but was indeterminate as to whether the lesion was benign or malignant. The diagnosis of dermoid cyst was made intra-operatively with frozen section. Although the diagnosis could not be made pre-operatively this retrospective report highlights the difficulty in evaluating cystic pancreatic lesions by imaging and summarizes the current body of knowledge on this rare entity.

Orthostatic hypotension as an unusual clinical manifestation of pheochromocytoma: a case report.
Bortnik, Miriam; Occhetta, Eraldo; Marino, Paolo
2008-08-01
Pheochromocytoma is a rare endocrine tumor which can have a highly variable presentation related to increased catecholamine secretion. We report the case of a 74-year-old man in whom recurrent episodes of syncope due to orthostatic hypotension were the only clinical manifestations of this challenging entity. Diagnosis of pheochromocytoma was achieved by biochemical test samples and computed tomography scans. Surgical excision of the tumor resulted in clinical improvement with normalization of catecholamine concentrations and no more episodes of orthostatic hypotension during a follow-up of 24 months. Although rare, pheochromocytoma may frequently cause disorders of orthostatic tolerance; because of its meaningful implications, screening for this entity should be considered in case of recurrent syncopal episodes due to new-onset orthostatic hypotension.

Cutaneous metastasis from transitional cell bladder carcinoma is a rare clinical entity associated with poor prognosis. We present a case of cutaneous metastasis arising from a transitional cell bladder carcinoma in a male patient who had undergone a radical cystectomy and bilateral ureterostomy 17 months previously. The cutaneous metastasis became evident 3 months before the manifestations of generalized recurrent disease. An awareness of this rare clinical entity and high index of suspicion is needed to rule out metastatic spread in patients with a previous history of transitional cell bladder carcinoma presenting with cutaneous nodules. Definitive diagnosis requires a histological confirmation, but prognosis is generally poor.

Cystic hepatic neoplasms are rare tumors, and are classified into two separate entities: mucinous cystic neoplasms (MCNs) and intraductal papillary mucinous neoplasms of the bile duct (IPMN-B). We report the case of a 56-year-old woman who presented with abdominal pain and jaundice due to the presence of a large hepatic multilocular cystic tumor associated with an intraductal tumor. Partial hepatectomy with resection of extrahepatic bile ducts demonstrated an intrahepatic MCN and an intraductal IPMN-B. This is the first report of the simultaneous occurrence of these two histologically distinct entities in the liver.
A case of adult anaplastic cerebellar ganglioglioma
Bouali, Sofiene; Maatar, Nidhal; Zehani, Alia; Mahmoud, Maha; Kallel, Jalel; Jemel, Hafedh
2018-01-01
Background: Anaplastic posterior fossa ganglioglioma in adults is exceedingly rare. To date, only one case of adult anaplastic posterior fossa ganglioglioma has been reported in the English literature and none has been described at the cerebellum. To our knowledge, this report is the third case of malignant posterior fossa ganglioglioma in adults and the first at the cerebellum. In general, this entity can be misdiagnosed preoperatively as a primary posterior fossa neoplasm, and by reporting our clinical and radiographic observations we want to add to the existing literature on this rare entity. Case Description: A 40-year-old man presented with a history of headaches and dizziness and progressive gait disturbance and was diagnosed with anaplastic ganglioglioma in the posterior fossa. Conclusions: Although rare, our case demonstrates that anaplastic ganglioglioma should be considered in the differential diagnosis of infratentorial tumors in adult patients. PMID:29527389
A curvilinear, anisotropic, p-version, brick finite element based on geometric entities

Hinnant, Howard E.
1992-01-01
A 'brick' solid finite element is presently developed on the basis of the p-version analysis, and used to demonstrate the FEM concept of 'geometric entities'. This method eliminates interelement discontinuities between low- and high-order elements, allowing very fine control over the shape-function order in various parts of the model. Attention is given to the illustrative cases of a one-element model of an elliptic pipe, and a square cross-section cantilevered beam.
High Grade Serous Cystadenocarcinoma of Testis-Case Report of a Rare Ovarian Epithelial Type Tumour
Nayanar, Sangeetha K; Varadharajaperumal, R; Satheeshbabu, TV; Balasubramanian, Satheesan
2017-01-01
Ovarian epithelial type tumour of testis are extremely rare tumours that resemble ovarian surface epithelial tumours. They usually present as testicular or paratesticular tumours and can be serous, mucinous, endometrioid or Brenner tumour. Serous and mucinous types account for the majority of tumours. The tumours are benign, borderline or malignant, commonly borderline. Here, we report a case of high grade serous cyst adenocarcinoma of testis which manifested as extensive metastasis in supraclavicular, mediastinal and abdominopelvic groups of lymph nodes, lung and adrenal gland without clinical evidence of an overt primary tumour. We report this case so as to make clinicians and pathologists aware of this rare entity and to stress on the fact that this rare entity should be kept in mind when evaluating cases of metastatic adenocarcinoma in male patients.

Modern manufacturing entities often operate in capital groups, and their role is sometimes limited to the function of cost centers. From the legal point of view, however, they are separate entities obliged to apply transfer pricing regulations. Meeting the requirements of the arm's length principle can be very difficult at this time, given the relationships and conflicts of interest in the capital group. Complexity increases in capital groups operating in different countries, due to differences in tax regulations. The main purpose of the paper is to demonstrate that the need to valuate the sale of finished goods to a manufacturing entity, which is a subject to a different tax jurisdiction, may lead to a problem of compliance with the arm's length principle. In addition, the paper proposes a methodology for comparability analysis that may be used by manufacturing entities to defend conditions of setting transfer pricing. The paper presents the different functional profiles of manufacturing entities and points out the difficulties that they may encounter when preparing the comparability analysis. It has also been noted that there are differences in transfer pricing regulations in different countries, for example by analyzing Polish and Czech regulations. The lack of uniform benchmarking legislation can cause inconsistencies in the selection of comparable data, resulting in differences in transfer pricing. The paper uses the method of legal regulation review and analysis of results of published studies concerning the scope of transfer pricing and comparability analysis. The paper also adopts a case study analysis.

To describe a case of metastatic renal cell carcinoma (RCC) masquerading as a jugular foramen paraganglioma (JP). To compare imaging findings between skull base metastatic RCC and histologically proven paraganglioma. A case of unexpected metastatic skull base RCC is reviewed. Computed tomography (CT) and magnetic resonance imaging (MRI) were compared between 3 confirmed cases of JP and our case of metastatic RCC. Diffusion-weighted MRI (DW-MRI) sequences and computed apparent diffusion coefficient (ADC) values were compared between these entities. A 55-year-old man presents with what appears clinically and radiographically to be JP. The tumor was resected, then discovered on postoperative pathology to be metastatic RCC. Imaging was retrospectively compared between 3 histologically confirmed cases of JP and our case of skull base RCC. The RCC metastasis was indistinguishable from JP on CT and traditional MRI but distinct by ADC values calculated from DW-MRI. Metastatic RCC at the skull base may mimic the clinical presentation and radiographic appearance of JP. The MRI finding of flow voids is seen in both paraganglioma and metastatic RCC. Diffusion-weighted MRI is able to distinguish these entities, highlighting its potential utility in distinguishing skull base lesions.

A number of neurological entities have been associated with systemic lupus erythematosus (SLE). Gullian-Barre syndrome (GBS) as a presenting feature of SLE remains uncommon with just 9 cases reported in the last half-century with the first case reported in 19641-9 (Table 1). We report a young female presenting with GBS in whom SLE and WHO class V lupus nephritis (LN) was subsequently diagnosed. The neurological symptoms partially responded to pulse methylprednisone, intravenous immunoglobulin (IVIG) and plasmapheresis.
Osteolytic Bone Lesions - A Rare Presentation of AML M6.

Acute myeloid leukemia (AML) M6 is a rare form of AML accounting for < 5 % of all AML. Extramedullary involvement is very rarely seen in this entity. Skeletal lesion has not been described in AML M6 before. We discuss the case of a 17 year old boy with AML M6, who presented with osteolytic lesion of right humerus. He was treated with induction and consolidation chemotherapy. The present case is the first report in literature of AML M6 presenting with skeletal lesions.

Pregnancy-related renal diseases are unique and need special attention, both for diagnosis and management. The major confounding factors for diagnosis are the physiological multiorgan changes that occur throughout the gestational period. Proper diagnosis of the renal disease is also important, given the impact of varied management options both on the maternal and fetal health. A young middle-aged female with a long-standing history of diabetes presented to the hospital with worsening proteinuria in her second trimester of pregnancy. Clinical history, examinations, and laboratory analysis did not give any clues for diagnosis of a specific disease entity. This led us to take the risk of renal biopsy for a tissue diagnosis. The odds of renal biopsy favored the management decision in her case, thereby avoiding the confusions prior to biopsy. The pathological diagnosis is a surprise though not a unique entity on its own (minimal change disease in pregnancy). The case illustrates the disparity of clinical presentations and the pathology in patients, and the importance of renal biopsy in pregnant patients in particular.

Tuberculosis (tb) of the chest wall is uncommon and it represents less than 5% of all cases of musculoskeletal tb and only 1-2% of tb. We present the case of an elderly woman with tb of the chest wall secondary to a nodal tb with an unusual presentation. The diagnosis of this entity is difficult because the disease often mimics other diseases such as pyogenic abscess, chest wall.

Fetus-in-fetu (FIF) is a rare entity in which malformed parasitic twin grows inside the body of its twin. It is most commonly presented with mass in the abdomen. We present a case of a 15-year-old boy who presented with abdominal mass since infancy. Radiological investigations are suggestive of FIF. Intraoperatively, malformed fetus in a sac was found and excised. Postoperatively the patient recovers well and was put on follow-up. PMID:28942402

Intratendinous deposits of hydroxyapatite crystals are very common, particularly in the rotator cuff. In rare cases, the calcium located in the thickness of the supraspinatus tendon can suffer intraosseous migration into the greater tuberosity. We present a case of this rare entity: a 28-year-old patient who attended with pain and functional weakness in the left shoulder. The plain radiograph showed a sclerotic lesion in the greater tuberosity of the humeral head with a radiolucent halo. The MRI showed a lytic lesion containing the calcium inside and associated with an extensive pattern of oedema of the accompanying bone marrow. A plain radiograph taken 6 months before showed a calcifying tendinitis in the thickness of the supraspinatus tendon. A large number of entities can present as single sclerotic lesions of the humeral head. The diagnostic key lies in the existence of the calcifying tendinitis in the earlier study. The treatment of this disease consists of surgical removal of the calcium. The recognition of this entity is important to avoid unnecessary complementary tests and aggressive surgery, given that the surgical treatment is curative and leads to disappearance of the symptoms.
Cervical necrotizing fasciitis of nonodontogenic origin: case report and review of literature.
Suárez, Aldo; Vicente, Mario; Tomás, Jose A; Floría, Luis M; Delhom, José; Baquero, Mari C
2014-11-01
Cervical necrotizing fasciitis (CNF) is a potentially fatal infection characterized by generalized necrosis of the cervical fascia that progresses rapidly. The incidence of this entity corresponds to 2.6% of all infections of the head and neck. The most frequent primary origin is dental infection, although other causes exist that should be evaluated.Delay in the diagnosis of this entity may lead to rapid progression and fatal outcome. Patients often present immunosuppression or systemic diseases that predispose them to this pathology. Cervical necrotizing fasciitis is associated with mortality rates of 7% to 20% depending on the extension of the cervical lesion. The highest rates correspond to cases that progress to mediastinitis or septic shock, which are the main and most frequent complications. Early detection and adequate emergency treatment are critical in the management of these patients and may reduce morbimortality and improve survival. The emergency services should be prepared to manage such cases efficiently, through a multidisciplinary treatment by coordinating emergency surgery with critical support and clinical stabilization of patients.We present a case of CNF of non odontogenic origin managed in our hospital.

The clinical history and histological features of seven cases of granulomatous mastitis are presented. The lesion occurs in young parous women as a tender extra-areolar breast lump. Histologically, non-caseating discrete granulomas are present, confined to breast lobules with, in three cases, coalescence of the granulomas and microabscess formation. Pathogenesis of the changes is discussed. It is thought that granulomatous mastitis is an entity morphologically distinct from duct ectasia/plasma cell mastitis and the commoner forms of granulomatous breast diseases. Images PMID:6889612

Amyand's hernia, a rare entity in the surgical pathology, presupposes the presence of the vermiform appendix inside a inguinal hernia sac (1). The hernia sac peritonitis by appendix swelling is even more rare, very few cases being presented in the surgical literature (1). The preoperatory diagnosis of Amyand's hernia is therefore very difficult. We herein present the case of a 71-year old male patient, operated on an emergency basis for hernia, which eventually turned out to be Amyand's hernia, a case which determined us to research the literature dedicated to this topic.

Non-immune hydrops fetalis (NIHF) is a challenging entity as it represents the end stage of several different disorders. Renal and genitourinary causes of NIHF are rare and include congenital renal malformations, tumors and ureter-urethra disorders. Herein, two NIHF cases with different renal causes were presented. The first case that had antenatal NIHF was diagnosed neonatal Bartter syndrome. The second case of NIHF with antenatal large cyst in the surrenal gland area required surgery and ectopic renal cyst was diagnosed. To our best of knowledge, these are the first reports of NIHF associated with neonatal Bartter syndrome and ectopic renal cyst in neonates. Although it may be coincidental, these cases suggest that both neonatal Bartter syndrome and unilateral ectopic renal cyst may cause NIHF development in neonates by several different mechanisms. Therefore, these two rare entities should be suspected in cases of NIHF with similar findings.

2014-01-01
INTRODUCTION Solid pseudo papillary pancreatic tumour is a rare entity. The atypical presentation causes a delayed or misdiagnosis of these pathology. It commonly affects the female population in the 2nd and 3rd decade of life. The presentation varies from non-specific abdominal pain to incidental findings in asymptomatic patients. It is a low-grade premalignant condition that is curable by excision of the tumour. PRESENTATION OF CASE This paper presents a 17-year-old girl with intra-abdominal mass diagnosed with solid pseudo papillary tumour that underwent Whipple's procedure. DISCUSSION We discuss the presentations, diagnosis and pathology findings of this rare pathology. CONCLUSION The diagnosis remains an enigma in view of the nature and location of the tumour. Resection is still the best choice remains for this condition. PMID:25462046
Case Report: A giant but silent adrenal pheochromocytoma – a rare entity

Herein we report a rare entity of a giant adrenal pheochromocytoma in a fifty-year-old male presenting with a vague abdominal pain. A computerised tomogram of the abdomen revealed a well-defined left supraadrenal giant lesion with no evidence of invasion to surrounding structures.The patient underwent surgical excision without any untoward postoperative events. Histopathological study revealed a benign pheochromocytoma. This report highlights the importance of acknowledging the fact that sometimes a giant adrenal pheochromocytoma can present with paucity of clinical signs and symptoms.Thorough investigations and a multidisciplinary team approach may lead to a better outcome in these patients.

Primary malignancies of the heart are so rare that most of the available data come from case reports or large single-center-based studies, with the overall incidence of 0.02% in the United States. Diagnosis in case of an isolated pericardial effusion as presentation is challenging, and determining that an angiosarcoma is even more challenging. Here, we presented a rare case of pericardial angiosarcoma which presented to us with tamponade. The patient eventually was diagnosed through pericardiectomy. A multimodality approach was attempted to treat the cancer. The clinical details of such a unique disease entity inspired us to present it as a case report.
[On the benefits to keep using the asperger diagnosis].
Delcommenne, M; Francolini, M; Bon, O L
The purpose of this paper is to examine the possible benefits to keep using the diagnosis of Asperger's syndrome. We first describe the evolution of this entity over time and within nomenclature bases such as the ICD- 10, the CFTMEA and the last versions of DSM. Then, we discuss more precisely the impact of the decision made in the DSM-5 to suppress the Asperger syndrome as a differentiated entity within the pervasive developmental disorders (PDD). This disorder chapter by the way also disappears and is replaced by Autism Spectrum Disorder (ASD). We present here three clinical cases encountered in an outpatient general child psychiatry clinic : 1 case was diagnosed as Asperger syndrome, 1 as infantile autism (early infantile autism) and 1 as another pervasive developmental disorder (psychotic disharmony). The objective was to expose the commonali ties and differences between these three entities. We conclude that keeping using the Asperger diagnosis is important for the clinical management of these clinical situations but also for the individual, his or her family and society at large.

Large structured databases of pathology findings are valuable in deriving new clinical insights. However, they are labor intensive to create and generally require manual annotation. There has been some work in the bioinformatics community to support automating this work via machine learning in English. Our contribution is to provide an automated approach to construct such structured databases in Chinese, and to set the stage for extraction from other languages. We collected 2104 de-identified Chinese benign and malignant breast pathology reports from Hunan Cancer Hospital. Physicians with native Chinese proficiency reviewed the reports and annotated a variety of binary and numerical pathologic entities. After excluding 78 cases with a bilateral lesion in the same report, 1216 cases were used as a training set for the algorithm, which was then refined by 405 development cases. The Natural language processing algorithm was tested by using the remaining 405 cases to evaluate the machine learning outcome. The model was used to extract 13 binary entities and 8 numerical entities. When compared to physicians with native Chinese proficiency, the model showed a per-entity accuracy from 91 to 100% for all common diagnoses on the test set. The overall accuracy of binary entities was 98% and of numerical entities was 95%. In a per-report evaluation for binary entities with more than 100 training cases, 85% of all the testing reports were completely correct and 11% had an error in 1 out of 22 entities. We have demonstrated that Chinese breast pathology reports can be automatically parsed into structured data using standard machine learning approaches. The results of our study demonstrate that techniques effective in parsing English reports can be scaled to other languages.

In a sequence of papers on the topic of message construction for interstellar communication by means of a cosmic language, the present author has discussed various significant requirements such a lingua should satisfy. The author's Lingua Cosmica is a (meta) system for annotating contents of possibly large-scale messages for ETI. LINCOS, based on formal constructive logic, was primarily designed for dealing with logic contents of messages but is also applicable for denoting structural properties of more general abstractions embedded in such messages. The present paper explains ways and means for achieving this for a special case: recursive entities. As usual two stages are involved: first the domain of discourse is enriched with suitable representations of the entities concerned, after which properties over them can be dealt with within the system itself. As a representative example the case of Russian dolls (Matrjoshka's) is discussed in some detail and relations with linguistic structures in natural languages are briefly exploited.
Accuracy control in Monte Carlo radiative calculations
NASA Technical Reports Server (NTRS)
Almazan, P. Planas
1993-01-01
The general accuracy law that rules the Monte Carlo, ray-tracing algorithms used commonly for the calculation of the radiative entities in the thermal analysis of spacecraft are presented. These entities involve transfer of radiative energy either from a single source to a target (e.g., the configuration factors). or from several sources to a target (e.g., the absorbed heat fluxes). In fact, the former is just a particular case of the latter. The accuracy model is later applied to the calculation of some specific radiative entities. Furthermore, some issues related to the implementation of such a model in a software tool are discussed. Although only the relative error is considered through the discussion, similar results can be derived for the absolute error.
Bietti's tapetoretinal degeneration with marginal corneal dystrophy crystalline retinopathy.
Welch, R B
1977-01-01
In 1937 Bietti reported a tapetoretinal degeneration with associated corneal deposits at the limbus. The hallmark of the disease was the crystalline characteristics of the retinal spots as well as those at the corneal limbus. Bagolini and Ioli-Spade in 1968 presented a 30 year follow-up on Bietti's cases and presented six additional cases. The present report delas with this entity in Orientals, a Chinese woman and a Japanese man.

Crapp, Seth; Harrar, Dana; Strother, Megan; Wushensky, Curtis; Pruthi, Sumit
2012-04-01
We present a case of Rocky Mountain spotted fever encephalitis in a child imaged utilizing diffusion-weighted MRI. Although the imaging and clinical manifestations of this entity have been previously described, a review of the literature did not reveal any such cases reported in children utilizing diffusion-weighted imaging. The imaging findings and clinical history are presented as well as a brief review of this disease.
The definitions of information and meaning two possible boundaries between physics and biology.
Barbieri, Marcello
2004-01-01
The standard approach to the definition of the physical quantities has not produced satisfactory results with the concepts of information and meaning. In the case of information we have at least two unrelated definitions, while in the case of meaning we have no definition at all. Here it is shown that both information and meaning can be defined by operative procedures, but it is also pointed out that we need to recognize them as a new type of natural entities. They are not quantities (neither fundamental nor derived) because they cannot be measured, and they are not qualities because are not subjective features. Here it is proposed to call them nominable entities, i.e., entities which can be specified only by naming their components in their natural order. If the genetic code is not a linguistic metaphor but a reality, we must conclude that information and meaning are real natural entities, and now we must also conclude that they are not equivalent to the quantities and qualities of our present theoretical framework. This gives us two options. One is to extend the definition of physics and say that the list of its fundamental entities must include information and meaning. The other is to say that physics is the science of quantities only, and in this case information and meaning become the exclusive province of biology. The boundary between physics and biology, in short, is a matter of convention, but the existence of information and meaning is not. We can decide to study them in the framework of an extended physics or in a purely biological framework, but we cannot avoid studying them for what they are, i.e., as fundamental components of the fabric of Nature.

Solitary extranevraxial plasmacytoma (SEP), as a clinical entity without signs of systemic myelomatosis, is extremely rare; it is difficult to find literature on the issue of patient management and proper course of action in the presence of associated pathology. The authors present a rare case of plasmacytoma of the skull vault associated with severe cardiac pathology, which made surgery extremely difficult and possible only through temporization of the interventions, as presented. We discuss our findings and opportunities for treatment in this case, which seemed unapproachable at presentation, in connection with the associated cardiac pathology. The case was followed-up for eight years with no recurrences.
Primary tuberculosis of the breast manifested as abscess: a rare case report.

Clinics in diagnostic imaging (178). Wünderlich syndrome and pseudoaneurysm.
Chung, Raymond; Chawla, Ashish; Peh, Wilfred Cg
2017-06-01
Wünderlich syndrome is a rare entity characterised by spontaneous retroperitoneal haemorrhage with renal origin. We present a case of Wünderlich syndrome secondary to clotting dyscrasia in a 64-year-old woman. The patient experienced a second Wünderlich haemorrhagic event with metachronous pseudoaneurysm formation, which was likely secondary to the large subcapsular haematoma stripping the renal capsule and tearing the cortical arteries. Selective pseudoaneurysm embolisations were successfully performed on both occasions. This clinical entity, its imaging differential diagnoses and management are discussed.

Round ligament leiomyoma: a rare manifestation of a common entity.
Deol, Madhvi; Arleo, Elizabeth Kagan
A 68-year-old woman with a history of multifocal uterine leiomyomas presented with left groin pain and was referred for cross-sectional imaging to assess for the presence of an inguinal hernia. In this patient, MRI demonstrated a round ligament leiomyoma encased in the proximal left inguinal canal. Leiomyomas are the most common benign gynecologic tumors, however round ligament leiomyomas are very rare. The purpose of this case report is to highlight a rare manifestation of a common entity.

Case report: a branchial cleft anomaly presenting as an oropharyngeal mass.
Mullin, David; Merz, Meredith
2011-12-01
Branchial anomalies are common cervical pathologic entities encountered in the field of otolaryngology and are typical in the pediatric and young adult populations. In most cases, these anomalies present as a cyst, sinus, or fistula in a rather stereotypical fashion. When a branchial anomaly deviates from the classic presentation, an improper diagnosis and inadequate management are more likely to occur, leading to an increased recurrence rate. We present a case of a 6-year-old girl with an incidental finding of a right posterior oropharyngeal wall mass, distinctly separate from the tonsillar fossa, which was found on pathologic analysis to be a branchial cleft anomaly. The theories regarding the pathogenesis of branchial anomalies are presented, along with other cases of atypical branchial anomalies.
A rare case of extra-nasopharyngeal angiofibroma of the septum in a female child.
Singh, G B; Shukla, S; Kumari, P; Shukla, I
2018-02-01
Extra-nasopharyngeal angiofibroma is a rare but distinct clinical entity, different from juvenile angiofibroma. This clinical record elucidates the only case of extra-nasopharyngeal angiofibroma arising from the septum in a female child, who presented with epistaxis. The histopathological diagnosis was confirmed by immunohistochemistry, and the case was managed surgically with no recurrence. In a female paediatric patient presenting with epistaxis, extra-nasopharyngeal angiofibroma (of the inferior turbinate) is a rare albeit important differential diagnosis, as it challenges the hormonal theory of angiofibroma aetiopathogenesis.

Primary mucinous cystadenocarcinoma (MCA) of breast is an exceedingly rare tumor with histologic resemblance to MCA arising in ovary, pancreas, and gastrointestinal tract. In this article, we present 2 additional cases of MCA of breast, one highlighting the diagnostic challenges of a rare entity that may potentially lead to unnecessary chemotherapy and the second case presenting with recurrence after 8 years of primary surgical excision defying the indolent behavior reported in the literature. To our knowledge, this is the first reported instance of such behavior.
The Effect of Realistic Contexts on Ontological Judgments of Novel Entities
Van Reet, Jennifer; Pinkham, Ashley M.; Lillard, Angeline S.
2014-01-01
Although a great deal of research has focused on ontological judgments in preschoolers, very little has examined ontological judgments in older children. The present study asked 10-year-olds and adults (N = 94) to judge the reality status of known real, known imagined, and novel entities presented in simple and elaborate contexts and to explain their judgments. Although judgments were generally apt, participants were more likely to endorse imagined and novel entities when the entities were presented in elaborate contexts. When asked to explain their reasoning, participants at both ages cited firsthand experience for real entities and general knowledge for imagined entities. For novel entities, participants referred most to indirect experiences when entities were presented in simple contexts and to general knowledge when those entities were presented in elaborate contexts. These results suggest that rich contextual information continues to be an important influence on ontological judgments past the preschool years. PMID:25914442

Sweet Syndrome: A Review and Update.
Villarreal-Villarreal, C D; Ocampo-Candiani, J; Villarreal-Martínez, A
2016-06-01
Sweet syndrome is the most representative entity of febrile neutrophilic dermatoses. It typically presents in patients with pirexya, neutrophilia, painful tender erytomatous papules, nodules and plaques often distributed asymmetrically. Frequent sites include the face, neck and upper extremities. Affected sites show a characteristical neutrophilic infiltrate in the upper dermis. Its etiology remains elucidated, but it seems that can be mediated by a hypersensitivity reaction in which cytokines, followed by infiltration of neutrophils, may be involved. Systemic corticosteroids are the first-line of treatment in most cases. We present a concise review of the pathogenesis, classification, diagnosis and treatment update of this entity.

Right fusiform response patterns reflect visual object identity rather than semantic similarity.
Bruffaerts, Rose; Dupont, Patrick; De Grauwe, Sophie; Peeters, Ronald; De Deyne, Simon; Storms, Gerrit; Vandenberghe, Rik
2013-12-01
We previously reported the neuropsychological consequences of a lesion confined to the middle and posterior part of the right fusiform gyrus (case JA) causing a partial loss of knowledge of visual attributes of concrete entities in the absence of category-selectivity (animate versus inanimate). We interpreted this in the context of a two-step model that distinguishes structural description knowledge from associative-semantic processing and implicated the lesioned area in the former process. To test this hypothesis in the intact brain, multi-voxel pattern analysis was used in a series of event-related fMRI studies in a total of 46 healthy subjects. We predicted that activity patterns in this region would be determined by the identity of rather than the conceptual similarity between concrete entities. In a prior behavioral experiment features were generated for each entity by more than 1000 subjects. Based on a hierarchical clustering analysis the entities were organised into 3 semantic clusters (musical instruments, vehicles, tools). Entities were presented as words or pictures. With foveal presentation of pictures, cosine similarity between fMRI response patterns in right fusiform cortex appeared to reflect both the identity of and the semantic similarity between the entities. No such effects were found for words in this region. The effect of object identity was invariant for location, scaling, orientation axis and color (grayscale versus color). It also persisted for different exemplars referring to a same concrete entity. The apparent semantic similarity effect however was not invariant. This study provides further support for a neurobiological distinction between structural description knowledge and processing of semantic relationships and confirms the role of right mid-posterior fusiform cortex in the former process, in accordance with previous lesion evidence. © 2013.

Extraocular muscle entrapment in a nondisplaced orbital fracture, although a well-known entity in pediatric trauma, is atypical in adults. It can present with a triad of bradycardia, nausea, and in rare cases, syncope, and result in severe fibrosis of damaged and incarcerated muscle. We present a case of muscle entrapment in a partially nondisplaced two-wall orbital fracture with accompanying preoperative bradycardia and intraoperative asystole in an adult PMID:26576246
Demodex Folliculitis of the Scalp: Clinicopathological Study of an Uncommon Entity.
Helou, Wissam; Avitan-Hersh, Emily; Bergman, Reuven
2016-09-01
Demodex is a saprophytic mite in humans commonly present in the pilosebaceous units, which has been implicated as a pathogen in several skin conditions. The clinical presentation and histopathology of Demodex folliculitis of the scalp have been described in only a few case reports. This study was performed to further elucidate the clinicopathological features of this entity. We have studied 333 consecutively submitted scalp biopsies performed for hair loss and alopecia. All specimens were completely step-sectioned. Biopsies with Demodex mites were further studied histopathologically, and the patients' clinical files were reviewed. There were 17 biopsies (5.1%) with Demodex in at least 1 pilosebaceous unit. Based on the clinical presentation, histopathology, and response to therapy, Demodex was considered to be nonpathogenic in 13 cases. The remaining 4 cases were characterized by hair loss, scalp erythema, scales, and pustules. There were 2 or more pilosebaceous units with Demodex along mononuclear and/or neutrophilic infiltrates around and in the involved follicles and occasionally granulomas. All 4 cases responded completely to metronidazole therapy. In conclusion, Demodex is infrequently found in scalp biopsies for hair loss and alopecia, and, in most cases, it does not seem to be pathogenic. Occasionally, however, it is associated with folliculitis characterized by hair loss, erythema, scales, and pustules clinically; neutrophilic and/or mononuclear-cell folliculitis with occasional granulomas histopathologically; and a prompt response to anti-Demodex therapy.
Case Report: Diagnosis of a Rare Plaque-Like Dermal Fibroma Successfully Treated With Mohs Surgery.
Gill, Pavandeep; Arlette, John; Shiau, Carolyn J; Abi Daoud, Marie S
CD34-positive plaque-like dermal fibroma (PDF) is a poorly characterised benign dermal neoplasm that has a wide differential diagnosis. It can be mistaken for other entities on superficial biopsy and be overtreated, leading to unnecessary worry and extensive surgery. To report on an uncommon presentation of this entity, the histopathologic differential diagnosis of PDF, and a novel treatment method. Clinical and histopathological information was obtained for a PDF lesion on a 75-year-old man. On superficial biopsy, the PDF lesion was misinterpreted as a possible neurothekeoma. Successful Mohs surgery and genetic testing confirmed the diagnosis of PDF, and the patient received appropriate tissue-sparing surgical management. This case adds to our current knowledge about PDF and highlights the importance of early recognition of these lesions to direct appropriate diagnostic testing (full-thickness biopsy) and management. This case confirms successful management with Mohs surgery.

Munchausen syndrome is rare factitious disorder which entails frequent hospitalization, pathological lying and intentional production of symptoms for sick role. Management requires collateral history taking, sound clinical approach, exclusion of organicity and addressing psychological issues. A case which presented with unusual symptoms of similar dimension is discussed here. The case brings out finer nuances in evaluation and management of this entity. PMID:25535450
Anal canal duplication and triplication: a rare entity with different presentations.
Palazon, P; Julia, V; Saura, L; de Haro, I; Bejarano, M; Rovira, C; Tarrado, X
2017-05-01
Anal canal duplication (ACD) is the rarest of gastrointestinal duplications. Few cases have been reported. Most cases present as an opening in the midline, posterior to the normal anus. The aim of our revision is to contribute with eight new cases, some of them with unusual presentations: five presented as the typical form, one with a perianal nodule, and two presented as two separate orifices (anal canal triplication). Complete excision was performed in all patients with no complications. ACD is the most distal and the least frequent digestive duplication. Its treatment should be surgical excision, to avoid complications such as abscess, fistulization, or malignization. Anal canal triplication has never been described before.

Lau, Steven K M; Cykowski, Matthew D; Desai, Shiv; Cao, Ying; Fuller, Gregory N; Bruner, Janet; Okazaki, Ian
2015-05-01
To report a case of primary rhabdomyosarcoma (RMS) of the pineal gland in an adult, as well as review the literature on this rare entity. The case is compared with previous reports of similar entities, with emphasis on this patient's characteristics and clinical presentation, investigations, and management. Diagnosis of primary RMS of the pineal gland was based on the presence of strap cells and multinucleated myotube-like structures, as well as tumor cell expression of skeletal muscle markers consistent with myogenic differentiation. Multimodality treatment was initiated based on pediatric protocols. Unfortunately, the disease progressed on treatment, and the patient survived only 5 months from diagnosis. Pineal RMS is a rare disease with poor prognosis. Optimal management is unknown but likely to involve aggressive multimodality therapy. Copyright© by the American Society for Clinical Pathology.

Obstructive hydrocephalus secondary to enlarged Virchow-Robin Spaces (VRS) is a rare entity, with only a few cases reported in the literature. Presenting symptoms vary widely from headaches to dizziness. We report a case of a 31-year-old man who presented with pulsatile tinnitus and magnetic resonance imaging showing obstructive hydrocephalus secondary to tumefactive VRS. After a cerebrospinal fluid diversion procedure in the form of an endoscopic third ventriculostomy, he had almost complete resolution of his symptoms. This is the first case of obstructive hydrocephalus secondary to enlarged VRS, presenting with pulsatile tinnitus. Copyright © 2017 Elsevier Inc. All rights reserved.
ED breast cases and other breast emergencies.
Khadem, Nasim; Reddy, Sravanthi; Lee, Sandy; Larsen, Linda; Walker, Daphne
2016-02-01
Patients with pathologic processes of the breast commonly present in the Emergency Department (ED). Familiarity with the imaging and management of the most common entities is essential for the radiologist. Additionally, it is important to understand the limitations of ED imaging and management in the acute setting and to recognize when referrals to a specialty breast center are necessary. The goal of this article is to review the clinical presentations, pathophysiology, imaging, and management of emergency breast cases and common breast pathology seen in the ED.
Facial diplegia: a clinical dilemma.
Chakrabarti, Debaprasad; Roy, Mukut; Bhattacharyya, Amrit K
2013-06-01
Bilateral facial paralysis is a rare clinical entity and presents as a diagnostic challenge. Unlike its unilateral counterpart facial diplegia is seldom secondary to Bell's palsy. Occurring at a frequency of 0.3% to 2% of all facial palsies it often indicates ominous medical conditions. Guillian-Barre syndrome needs to be considered as a differential in all given cases of facial diplegia where timely treatment would be rewarding. Here a case of bilateral facial palsy due to Guillian-Barre syndrome with atypical presentation is reported.
Angiofibroma of the nasal cavity in 13 dogs.
Burgess, K E; Green, E M; Wood, R D; Dubielzig, R R
2011-12-01
This case series describes a rare entity, nasal angiofibroma, in 13 dogs that were presented to the University of Wisconsin, School of Veterinary Medicine from 1988 to 2000. All dogs in this case series presented with clinical signs and radiographic changes that were strongly suggestive of a locally invasive neoplasm. However, histopathology completed on transnostral core biopsy samples revealed benign appearing vascular proliferation with secondary lymphosuppurative inflammation was established despite cytologic criteria of malignancy present in five dogs. On the basis of the outcomes in this case series, nasal angiofibroma should be considered a differential for dogs presenting with clinical signs consistent with a malignant nasal tumour. © 2011 Blackwell Publishing Ltd.

We investigated the critical contribution of right ventral occipitotemporal cortex to knowledge of visual and functional-associative attributes of biological and non-biological entities and how this relates to category-specificity during confrontation naming. In a consecutive series of 7 patients with lesions confined to right ventral occipitotemporal cortex, we conducted an extensive assessment of oral generation of visual-sensory and functional-associative features in response to the names of biological and nonbiological entities. Subjects also performed a confrontation naming task for these categories. Our main novel finding related to a unique case with a small lesion confined to right medial fusiform gyrus who showed disproportionate naming impairment for nonbiological versus biological entities, specifically for tools. Generation of visual and functional-associative features was preserved for biological and non-biological entities. In two other cases, who had a relatively small posterior lesion restricted to primary visual and posterior fusiform cortex, retrieval of visual attributes was disproportionately impaired compared to functional-associative attributes, in particular for biological entities. However, these cases did not show a category-specific naming deficit. Two final cases with the largest lesions showed a classical dissociation between biological versus nonbiological entities during naming, with normal feature generation performance. This is the first lesion-based evidence of a critical contribution of the right medial fusiform cortex to tool naming. Second, dissociations along the dimension of attribute type during feature generation do not co-occur with category-specificity during naming in the current patient sample.

Tuberculous mastoiditis is a well-documented entity with decreasing incidence in recent years. Tuberculous osteitis of the skull is even rarer. The case of a 58-year-old male with tuberculous mastoiditis complicated by extensive tuberculous osteitis of the skull is presented. This case serves to demonstrate both the difficulty in establishing the diagnosis of tuberculosis and the potentially disastrous consequences of the disease.

Inflammatory myofibroblastic tumors (IMTs) or inflammatory pseudotumors (IPs) have been extensively discussed in the literature. They are usually found in the lung and upper respiratory tract. However, reporting of cases involving the biliopancreatic region has increased over recent years. Immunohistochemical study of these lesions limited to the pancreatic head or distal bile duct seems to be compatible with those observed in a new entity called autoimmune pancreatitis, but usually intense fibrotic reaction (zonation) predominates producing a mass. When this condition is limited to the pancreatic head, the common bile duct might be involved by the inflammatory process and jaundice may occur often resembling adenocarcinoma of the pancreas. We have previously reported a case of IMT arising from the bile duct associated with autoimmune pancreatitis which is an extremely rare entity. Four years after Kaush-Whipple resection, radiological examination on routine follow-up revealed a tumor mass, suggesting local recurrence. Ultrasound-guided FNA confirmed our suspicious diagnosis. This present case, as others, suggests that persistent follow-up is necessary in order to prevent irreversible liver damage at this specific location. PMID:16804988
Towards an Obesity-Cancer Knowledge Base: Biomedical Entity Identification and Relation Detection
Lossio-Ventura, Juan Antonio; Hogan, William; Modave, François; Hicks, Amanda; Hanna, Josh; Guo, Yi; He, Zhe; Bian, Jiang
2017-01-01
Obesity is associated with increased risks of various types of cancer, as well as a wide range of other chronic diseases. On the other hand, access to health information activates patient participation, and improve their health outcomes. However, existing online information on obesity and its relationship to cancer is heterogeneous ranging from pre-clinical models and case studies to mere hypothesis-based scientific arguments. A formal knowledge representation (i.e., a semantic knowledge base) would help better organizing and delivering quality health information related to obesity and cancer that consumers need. Nevertheless, current ontologies describing obesity, cancer and related entities are not designed to guide automatic knowledge base construction from heterogeneous information sources. Thus, in this paper, we present methods for named-entity recognition (NER) to extract biomedical entities from scholarly articles and for detecting if two biomedical entities are related, with the long term goal of building a obesity-cancer knowledge base. We leverage both linguistic and statistical approaches in the NER task, which supersedes the state-of-the-art results. Further, based on statistical features extracted from the sentences, our method for relation detection obtains an accuracy of 99.3% and a f-measure of 0.993. PMID:28503356

Pernicious anemia is the most common cause of vitamin B12 deficiency in adults. This entity is associated with chronic atrophic gastritis. We report a case of pernicious anaemia in triplets. We also report a fourth case of cobalamin deficiency with antibodies against intrinsic factor and anti parietal cell antigen negative antibodies in a sibling. The present article reviews the pediatric presentation of pernicious anemia and highlights the possible existence of familial aggregation. Furthermore, the need for systematic familial screening and the usefulness of an endoscopic follow-up program in patients with pernicious anemia are evaluated.

DiGeorge syndrome is a congenital genetic disorder that affects the endocrine system, mainly the thymus and parathyroid glands. The syndrome produces different symptoms, which vary in severity and character between patients. It manifests with craniofacial dysmorphism and defects in the heart, parathyroid, and thymus. Patients can present with a palatal deformity and nasal speech. This rare entity is caused mainly due to deletion of chromosome 22q11.2. Radiographic evaluation of DiGeorge syndrome is necessary to define aberrant anatomy, evaluate central nervous system, craniofacial abnormalities, musculoskeletal system, and cardiothoracic contents. It also helps in planning surgical procedures and surgical reconstructions. We report a case of DiGeorge syndrome in a 4-month-old neonate and discuss the clinical, imaging, and cytogenetic findings that helped in the diagnosis of this rare entity.
Facebook Role Play Addiction - A Comorbidity with Multiple Compulsive-Impulsive Spectrum Disorders.
Nathan, Deeepa; Shukla, Lekhansh; Kandasamy, Arun; Benegal, Vivek
2016-06-01
Background Problematic Internet use (PIU) is an emerging entity with varied contents. Behavioral addictions have high comorbidity of attention deficit hyperactivity disorder and obsessive-compulsive spectrum disorders. Social networking site (SNS) addiction and role playing game (RPG) addiction are traditionally studied as separate entities. We present a case with excessive Internet use, with a particular focus on phenomenology and psychiatric comorbidities. Case presentation Fifteen-year-old girl with childhood onset attention deficit disorder, obsessive-compulsive disorder, adolescent onset trichotillomania, and disturbed family environment presented with excessive Facebook use. Main online activity was creating profiles in names of mainstream fictional characters and assuming their identity (background, linguistic attributes, etc.). This was a group activity with significant socialization in the virtual world. Craving, salience, withdrawal, mood modification, and conflict were clearly elucidated and significant social and occupational dysfunction was evident. Discussion This case highlights various vulnerability and sociofamilial factors contributing to behavioral addiction. It also highlights the presence of untreated comorbidities in such cases. The difference from contemporary RPGs and uniqueness of role playing on SNS is discussed. SNS role playing as a separate genre of PIU and its potential to reach epidemic proportions are discussed. Conclusions Individuals with temperamental vulnerability are likely to develop behavioral addictions. Identification and management of comorbid conditions are important. The content of PIU continues to evolve and needs further study.

Case presentation Fifteen-year-old girl with childhood onset attention deficit disorder, obsessive–compulsive disorder, adolescent onset trichotillomania, and disturbed family environment presented with excessive Facebook use. Main online activity was creating profiles in names of mainstream fictional characters and assuming their identity (background, linguistic attributes, etc.). This was a group activity with significant socialization in the virtual world. Craving, salience, withdrawal, mood modification, and conflict were clearly elucidated and significant social and occupational dysfunction was evident. Discussion This case highlights various vulnerability and sociofamilial factors contributing to behavioral addiction. It also highlights the presence of untreated comorbidities in such cases. The difference from contemporary RPGs and uniqueness of role playing on SNS is discussed. SNS role playing as a separate genre of PIU and its potential to reach epidemic proportions are discussed. Conclusions Individuals with temperamental vulnerability are likely to develop behavioral addictions. Identification and management of comorbid conditions are important. The content of PIU continues to evolve and needs further study. PMID:27156380

Massive cerebral involvement in fat embolism syndrome and intracranial pressure management.
Kellogg, Robert G; Fontes, Ricardo B V; Lopes, Demetrius K
2013-11-01
Fat embolism syndrome (FES) is a common clinical entity that can occasionally have significant neurological sequelae. The authors report a case of cerebral fat embolism and FES that required surgical management of intracranial pressure (ICP). They also discuss the literature as well as the potential need for neurosurgical management of this disease entity in select patients. A 58-year-old woman presented with a seizure episode and altered mental status after suffering a right femur fracture. Head CT studies demonstrated hypointense areas consistent with fat globules at the gray-white matter junction predominantly in the right hemisphere. This CT finding is unique in the literature, as other reports have not included imaging performed early enough to capture this finding. Brain MR images obtained 3 days later revealed T2-hyperintense areas with restricted diffusion within the same hemisphere, along with midline shift and subfalcine herniation. These findings steered the patient to the operating room for decompressive hemicraniectomy. A review of the literature from 1980 to 2012 disclosed 54 cases in 38 reports concerning cerebral fat embolism and FES. Analysis of all the cases revealed that 98% of the patients presented with mental status changes, whereas only 22% had focal signs and/or seizures. A good outcome was seen in 57.6% of patients with coma and/or abnormal posturing on presentation and in 90.5% of patients presenting with mild mental status changes, focal deficits, or seizure. In the majority of cases ICP was managed conservatively with no surgical intervention. One case featured the use of an ICP monitor, while none featured the use of hemicraniectomy.

Background Idiopathic granulomatous mastitis is an uncommon, benign entity with a diagnosis of exclusion. The typical clinical presentation of idiopathic granulomatous mastitis often mimics infection or malignancy. As a result, histopathological confirmation of idiopathic granulomatous mastitis combined with exclusion of infection, malignancy and other causes of granulomatous disease is absolutely necessary. Case Presentation We present a case of a young woman with idiopathic granulomatous mastitis, initially mistaken for mastitis as well as breast carcinoma, and successfully treated with a course of corticosteroids. Conclusion There is no clear clinical consensus regarding the ideal therapeutic management of idiopathic granulomatous mastitis. Treatment options include expectant management with spontaneous remission, corticosteroid therapy, immunosuppressive agents and extensive surgery for refractory cases. PMID:17662130
Prolonged social withdrawal disorder: a hikikomori case in Spain.
Ovejero, Santiago; Caro-Cañizares, Irene; de León-Martínez, Victoria; Baca-Garcia, Enrique
2014-09-01
The Japanese term hikikomori means literally 'to be confined'. Social withdrawal can be present in severe psychiatric disorders; however, in Japan, hikikomori is a defined nosologic entity. There have been only a few reported cases in occidental culture. We present a case report of a Spanish man with prolonged social withdrawal lasting for 4 years. This is a case of prolonged social withdrawal not bound to culture, as well as the second case of hikikomori reported in Spain. We propose prolonged social withdrawal disorder as a disorder not linked to culture, in contrast to hikikomori. Further documentation of this disorder is still needed to encompass all cases reported in Japan and around the world. © The Author(s) 2013.
A rare case of atypical pleomorphic adenoma arising from periocular ectopic lacrimal gland.
Wajda, Brynn N; Mancini, Ronald; Evers, Bret; Nick Hogan, R
2018-06-23
To describe features of atypical pleomorphic adenoma, a rare clinical entity, particularly when found in ectopic periocular lacrimal gland tissue. Case report of biopsy-confirmed periocular atypical pleomorphic adenoma. A 35-year-old female presented with a unique orbital lesion found to be ectopic lacrimal gland demonstrating atypical pleomorphic adenoma on formal histopathologic review. Pleomorphic adenoma is pathologically characterized as an epithelial lesion intermixed with mesenchymal elements. It is further classified as atypical with the presence of features such as hypercellularity, regions of necrosis or hyalinization, cellular dysplasia, capsular violation, and malignant characteristics without frank local extension or distant metastases. Due to its rarity, the natural history and prognosis of atypical pleomorphic adenoma is unclear. Physicians need to recognize this entity, and complete surgical excision with strict follow-up regimens are likely warranted.

Discovery of Predicate-Oriented Relations among Named Entities Extracted from Thai Texts
NASA Astrophysics Data System (ADS)
Tongtep, Nattapong; Theeramunkong, Thanaruk
Extracting named entities (NEs) and their relations is more difficult in Thai than in other languages due to several Thai specific characteristics, including no explicit boundaries for words, phrases and sentences; few case markers and modifier clues; high ambiguity in compound words and serial verbs; and flexible word orders. Unlike most previous works which focused on NE relations of specific actions, such as work_for, live_in, located_in, and kill, this paper proposes more general types of NE relations, called predicate-oriented relation (PoR), where an extracted action part (verb) is used as a core component to associate related named entities extracted from Thai Texts. Lacking a practical parser for the Thai language, we present three types of surface features, i.e. punctuation marks (such as token spaces), entity types and the number of entities and then apply five alternative commonly used learning schemes to investigate their performance on predicate-oriented relation extraction. The experimental results show that our approach achieves the F-measure of 97.76%, 99.19%, 95.00% and 93.50% on four different types of predicate-oriented relation (action-location, location-action, action-person and person-action) in crime-related news documents using a data set of 1,736 entity pairs. The effects of NE extraction techniques, feature sets and class unbalance on the performance of relation extraction are explored.
HGNET-BCOR Tumors of the Cerebellum: Clinicopathologic and Molecular Characterization of 3 Cases.

The central nervous system (CNS) high-grade neuroepithelial tumor with BCOR alteration (CNS HGNET-BCOR) is a recently described molecular entity. We report 3 new CNS HGNET-BCOR cases sharing common clinical presentation and pathologic features. The 3 cases concerned children aged 3 to 7 years who presented with a voluminous mass of the cerebellum. Pathologic features included proliferation of uniform spindle to ovoid cells with fine chromatin associated with a rich arborizing capillary network. Methylation profiling classified these cases as CNS HGNET-BCOR tumors. Polymerase chain reaction analysis confirmed the presence of internal tandem duplications in the C-terminus of BCOR (BCOR-ITD), a characteristic of these tumors, in all 3 cases. Immunohistochemistry showed a strong nuclear BCOR expression. In 2 cases, local recurrence occurred within 6 months. The third case, a patient who received a craniospinal irradiation after total surgical removal followed by a metronomics maintenance with irinotecan, temozolomide, and itraconazole, is still free of disease 14 months after diagnosis. In summary, CNS HGNET-BCOR represents a rare tumor occurring in young patients with dismal prognosis. BCOR nuclear immunoreactivity is highly suggestive of a BCOR-ITD. Whether CNS HGNET-BCOR should be classified among the category of "embryonal tumors" or within the category of "mesenchymal, nonmeningothelial tumors" remains to be clarified. Because CNS HGNET-BCOR share pathologic features and characteristic BCOR-ITD with clear cell sarcoma of the kidney, these tumors may represent local variants of the same entity.
Desmoid tumors of the abdominal wall: A case report
Overhaus, Marcus; Decker, Pan; Fischer, Hans Peter; Textor, Hans Jochen; Hirner, Andreas
2003-01-01
Background Desmoid tumors are slow growing deep fibromatoses with aggressive infiltration of adjacent tissue but without any metastatic potential. Case Presentation We report on two female patients with desmoid tumor of the abdominal wall who underwent primary resection. Both patients had a history of an earlier abdominal surgery. Preoperative evaluation included abdominal ultrasound, magnetic resonance imaging and computed tomography. The histology in both cases revealed a desmoid tumor. Conclusion Complete surgical resection is the first line management of this tumor entity. PMID:12890284
An Unusual Consolidation: Lobar Pulmonary Hemorrhage Due to Antithrombotic Therapy.
D'Amore, Katrina; Traficante, David; McGovern, Terrance; Propersi, Marco; Barnes, Stacey

Alveolar hemorrhage is a rare yet devastating clinical entity if not identified and treated aggressively. Exceedingly rare are the cases of anticoagulant-induced alveolar hemorrhage with very few cases described in the current literature. The nonspecific presentation of an alveolar hemorrhage makes its diagnosis and appropriate treatment difficult in the emergency department. We report a case of a patient on warfarin for atrial fibrillation who was initially misdiagnosed as having community-acquired pneumonia, but subsequently was identified to have a fatal alveolar hemorrhage.

Wilms' tumor (nephroblastoma), a primary renal neoplasm containing primitive blastema and embryonic glomerulotubular structures, is the most common malignant tumor of the urinary tract in children. There have been about 240 cases of adult Wilms' tumor reported in the world literature, however due to some differences in histologic findings, many cases have been reclassified as rhabdoid or clear cell sarcomas, both of which are recognized as separate entities. We report a case of an adult Wilms' tumor and discuss the clinical, radiographic and histologic features of this tumor.

Wandering spleen and gastric volvulus are two rare entities that have been described in association with congenital diaphragmatic hernia. The diagnosis is difficult and any delay can result in ischemia and necrosis of both organs. We present a case of a 13-year-old girl, previously operated on for anterior diaphragmatic hernia and intrathoracic gastric volvulus, that presented to our service for a subdiaphragmatic gastric volvulus recurrence associated with a wandering spleen. In this report we reviewed the literature, analyzing the clinical presentation, diagnostic assessment, and treatment options of both conditions, in particular in the case associated with diaphragmatic hernia.

Spinal epidural hematomas are uncommon in children. The diagnosis can be elusive as most cases present without a history of trauma, while symptoms can be atypical. We encountered a 35-month-old male presenting with nonspecific symptoms and no history of trauma. He later developed unilateral miosis and ptosis; MRI discovered a subacute cervicothoracic epidural which was promptly evacuated. The patient made an excellent recovery. We emphasize the frequent absence of identifiable trauma and the importance of thorough imaging when this entity is suspected. Miosis and ptosis, likely representing a partial Horner syndrome, is an extremely rare presentation, this being one of the only reported cases.

Necrotizing Infundibular Crystalline Folliculitis (NICF) is rare entity of unknown pathogenesis presenting as follicular crystalline papules arising in seborrheic areas. We report 2 cases of NICF in patients under targeted therapy for metastatic adenocarcinoma. In one case, the lesions reappeared cyclically every 3 weeks after each injection and in the other case, lesions persisted until disruption of the continuous oral therapy. Punch-biopsies demonstrated folliculitis with a plugging crystalline material associated with either bacteria or yeast. These are the first descriptions of drug-induced NICF.

While copper deficiency has long been known to cause cytopenias, copper deficiency myeloneuropathy is a more recently described entity. Here, we present the case of two clinically distinct presentations of acquired copper deficiency syndromes secondary to excessive use of zinc-containing denture adhesive over five years: myeloneuropathy and severe macrocytic anemia and neutropenia. Extensive laboratory testing and histologic evaluation of the liver and bone marrow, were necessary to rule out other disease processes and establish the diagnosis of copper deficiency. The initial presentation consisted of a myelopathy involving the posterior columns. Serum and urine copper were significantly decreased, and serum zinc was elevated. On second presentation (five years later), multiple hematological abnormalities were detected. Serum copper was again decreased, while serum zinc was elevated. Zinc overload is a preventable cause of copper deficiency syndromes. This rare entity presented herein highlights the importance of patient, as well as provider, education.

Intracerebellar malignant nerve sheath tumor in a child: case report and review of literature.
Joshi, Krishna Chaitanya; Chakravarthy, Hariprakash; Subramanian, Nirmala
2015-05-01
Intracerebellar malignant nerve sheath tumor (ICMNST) is an extremely rare entity, only two cases have been reported previously, and this is the first case to be reported in a child. The histogenesis, diagnosis, and management of this entity are very ambiguous, and natural history in a child is unknown. The authors report a 7-year-old girl who presented with ataxia and signs of raised intracranial pressure and discuss the challenges in diagnosis, surgical strategy, and treatment. Following gross total resection and radiation to tumor bed, the patient had unremarkable recovery and is recurrence free at 1-year follow-up. ICMNSTs are extremely rare tumors of the cerebellum. Preoperative radiological diagnosis is not possible due to its close radiological resemblance to other common posterior fossa tumors. Immunohistochemistry plays a pivotal role in clinching the diagnosis. Though the reported adult counterparts have shown dismal prognosis, the pediatric counterparts may fare better with good surgical resection followed by radiotherapy.
Occupational vocal cord dysfunction due to exposure to wood dust and xerographic toner.
Muñoz, Xavier; Roger, Alex; De la Rosa, David; Morell, Ferran; Cruz, Maria J
2007-04-01
Vocal cord dysfunction is a poorly understood entity that is often misdiagnosed as asthma. Both irritant and non-irritant vocal cord dysfunction have been described. This report presents two cases of irritant vocal cord dysfunction secondary to specific environmental exposure, the first to iroko and western red cedar wood (a carpenter) and the second to xerographic printing toner (a secretary). Several tests were performed, including chest radiographs, measurements of total serum immunoglobulin E, skin prick tests with common pneumoallergens (as well as iroko and western red cedar in the first case), pulmonary function studies, methacholine challenge testing, specific inhalation challenge performed with suspected agents in a single-blinded fashion, and peak expiratory flow testing and fiberoptic rhinolaryngoscopy (in case 1). During the specific inhalation challenge, the patients showed dysphonia, chest tightness, inspiratory stridor, and flattening of the inspiratory limb of the maximum flow-volume loop in spirometry, with no significant decreases in the level of forced expiratory volume in 1 second; fiberoptic rhinolaryngoscopy confirmed the diagnosis of vocal cord dysfunction in case 1. It is important to know that agents that can cause occupational asthma can also cause vocal cord dysfunction. The mechanisms by which these agents produce vocal cord dysfunction are unknown. The differences in the clinical presentation of the patients described relative to the reported cases suggest that more than one pathophysiological mechanism may be implicated in the genesis of this entity.

Male breast carcinomas are rare tumours, accounting for less than 1% of all malignancies in men. Intracystic Papillary Carcinoma (IPC) in males is a very rare entity, representing 5-7.5% of all male breast carcinomas. It lacks the classical clinical, radiological and cytological features of malignancy and usually presents as a benign-appearing lump. We report a case of Infiltrating Ductal Carcinoma (IDC) co-existing with intracystic papillary carcinoma in a 53-year-old male who presented with lump in the right breast.

We present a case of 38-year-old male with an extradural tumor which on histopathological examination showed features of inflammatory atypical meningioma (WHO Grade II). The intense inflammatory nature of osteolytic primary intraosseous meningioma has not been reported before. This entity deserves special mention because of the need for adjuvant therapy and proper follow-up.
Primary angiosarcoma of the spleen--CT, MR, and sonographic characteristics: report of two cases.

Primary angiosarcoma of the spleen is a rare entity, but it is the most common primary splenic malignancy. These tumors demonstrate an aggressive growth pattern and can be single or multiple. The diagnosis should be suspected in a patient who presents with splenomegaly but without evidence of lymphoma, malaria, leukemia, or portal hypertension. The tumor may also present with acute abdominal symptoms secondary to spontaneous splenic rupture. We describe two cases of primary angiosarcoma of the spleen with computed tomographic, magnetic resonance, and sonographic features.
Congenital hernia of cord: an often misdiagnosed entity
Raju, Rubin; Satti, Mohamed; Lee, Quoc; Vettraino, Ivana
2015-01-01
Congenital hernia of the cord, also known as umbilical cord hernia, is an often misdiagnosed and under-reported entity, easily confused with a small omphalocele. It is different from postnatally diagnosed umbilical hernias and is believed to arise from persistent physiological mid-gut herniation. Its incidence is estimated to be 1 in 5000. Unlike an omphalocele, it is considered benign and is not linked with chromosomal anomalies. It has been loosely associated with intestinal anomalies, suggesting the need for a complete fetal anatomical ultrasound evaluation. We present a case of a fetal umbilical cord hernia diagnosed in a 28-year-old woman at 21 weeks gestation. The antenatal and intrapartum courses were uncomplicated. It was misdiagnosed postnatally as a small omphalocele, causing unwarranted anxiety in the parents. Increased awareness and knowledge of such an entity among health professionals is important to prevent unwarranted anxiety from misdiagnosis, and inadvertent bowel injury during cord clamping at delivery.

[Amyloidosis maculosa: diagnosis in primary care].
Toribio da Pena, S R; Olmos, O; Borbujo, J; Bastos Amigo, J A; Jiménez-Sánchez, F; Alonso, A
1990-01-01
Amyloidosis maculosa is a clinical entity with low incidence factor in our medium, which basically affects middle-aged women. The lesion is characterised by the presence of poorly defined, hyperpigmented, brownish or greyish maculae that converge and focus basically on the upper back and shoulders, usually accompanied by pruritus. Three patients were erroneously catalogued for years as having pityriasis versicolor. Two of these patients presented a typical clinical amyloidosis maculosa, and the third presented a less common manifestation of the disease: a single, well-defined lesion in the subscapular region. We believe that the approach to the diagnosis of pityriasis versicolor with hyperpigmented lesions that do not respond to specific treatment should be revised. Although amyloidosis maculosa has a low incidence in our medium, it is an entity which should not be discarded in these cases.

Diffuse leptomeningeal glioneuronal tumor (DLGNT) was recently added to the World Health Organization classification of central nervous system tumors. DLGNT is a rare entity that occurs more commonly in pediatric patients, but occasional cases have been reported in adults. This tumor has been recognized as a distinct pathologic entity; however, its biologic behavior remains unclear. It is considered an indolent neoplasm, although considerable morbidity has been reported. For this reason, further characterization and collection of evidence are crucial. In this article, we reported a case of a 36-year-old woman with a DLGNT characterized by rapid, aggressive behavior. We also performed a review of the literature for reported cases of low-grade and high-grade forms involving adults and children. DLGNTs should no longer be considered only as low-grade tumors affecting pediatric patients. The spectrum of presentations also includes aggressive tumors affecting adults. Further clinical and pathologic data supported by cytogenetic and molecular investigations are mandatory to better characterize DLGNTs. Copyright © 2018 Elsevier Inc. All rights reserved.
Atypical presentations of methemoglobinemia from benzocaine spray.
Tantisattamo, Ekamol; Suwantarat, Nuntra; Vierra, Joseph R; Evans, Samuel J
2011-06-01
Widely used for local anesthesia, especially prior to endoscopic procedures, benzocaine spray is one of the most common causes of iatrogenic methemoglobinemia. The authors report an atypical case of methemoglobinemia in a woman presenting with pale skin and severe hypoxemia, after a delayed repeat exposure to benzocaine spray. Early recognition and prompt management of methemoglobinemia is needed in order to lessen morbidity and mortality from this entity.

[Painful tic convulsif: Case series and literature review].
Revuelta-Gutiérrez, Rogelio; Velasco-Torres, Héctor Sebastián; Vales Hidalgo, Lourdes Olivia; Martínez-Anda, Jaime Jesús
The coexistence of hemifacial spasm and trigeminal neuralgia, a clinical entity known as painful tic convulsive, was first described in 1910. It is an uncommon condition that is worthy of interest in neurosurgical practice, because of its common pathophysiology mechanism: Neuro-vascular compression in most of the cases. To present 2 cases of painful tic convulsive that received treatment at our institution, and to give a brief review of the existing literature related to this. The benefits of micro-surgical decompression and the most common medical therapy used (botulin toxin) are also presented. Two cases of typical painful tic convulsive are described, showing representative slices of magnetic resonance imaging corresponding to the aetiology of each case, as well as a description of the surgical technique employed in our institution. The immediate relief of symptomatology, and the clinical condition at one-year follow-up in each case is described. A brief review of the literature on this condition is presented. This very rare neurological entity represents less than 1% of rhizopathies and in a large proportion of cases it is caused by vascular compression, attributed to an aberrant dolichoectatic course of the vertebro-basilar complex. The standard modality of treatment is micro-vascular surgical decompression, which has shown greater effectiveness and control of symptoms in the long-term. However medical treatment, which includes percutaneous infiltration of botulinum toxin, has produced similar results at medium-term in the control of each individual clinical manifestation, but it must be considered as an alternative in the choice of treatment.

Mondor's disease of the breast. A retrospective review.
Salemis, Nikolaos S; Merkouris, Stamatios; Kimpouri, Konstantina
2011-01-01
Mondor's disease is a rare benign clinical entity characterized by thrombophlebitis of the superficial veins of the anterolateral thoraco-abdominal wall. Although several predisposing factors have been reported, the exact pathogenesis remains unclear. We retrospectively reviewed the medical records of all patients older than 14 years who were diagnosed with Mondor's disease of the breast at the Breast Cancer Surgery Unit of Army General Hospital over a 3-year period. Five cases of Mondor's disease were identified among 5717 breast examinations performed during the study period. In 4 patients the disease was considered to be idiopathic. Ultrasonography established the diagnosis in all patients but mammography was inconclusive in two cases due to the presence of dense breast tissue. Four patients received symptomatic treatment. All patients had complete clinical resolution within 2-8 weeks of presentation, and they are well without any evidence of recurrence for 3 to 32 months later. No cases were associated with breast cancer. Mondor's disease of the breast is a rare benign self-limiting clinical entity. Ultrasonography is the diagnostic modality of choice but mammography may be inconclusive in the presence of dense breast tissue. Awareness of this rare entity is mandatory to prevent an unnecessary biopsy whereas the patients should be reassured of the benign nature of this disorder. Thorough evaluation is however necessary to rule out an underlying breast cancer or another systemic disease.

[Primary cardiac lymphoma: a case report].
Parato, Vito Maurizio; Muscente, Francesca; Scarano, Michele
2017-01-01
Primary cardiac lymphomas are rare entities (1.3% of all primary cardiac tumors) of difficult clinical identification. We report a case of a primitive cardiac lymphoma in a 35-year-old immunocompetent patient, presenting with signs and symptoms of cardiac tamponade. Echocardiography revealed a lateral atrioventricular mass associated with large pericardial effusion. After pericardiocentesis, surgical excision was performed. Chemotherapy regimens were administered according to established protocols and were effective in inducing complete remission at 6 months.

Pleuroperitoneal mesothelioma is an extremely rare entity. Only few cases are reported worldwide. We hereby represent a case of pleural mesothelioma referred for F-18-Fluorodeoxyglucose positron emission tomography/computed tomography for response evaluation. Diffuse F-18-Fluorodeoxyglucose avid peritoneal and omental thickening noted which subsequently turned out to be mesothelial involvement on peritoneal biopsy. This case demonstrates the role of F-18-Fluorodeoxyglucose positron emission tomography/computed tomography in detecting other sites of involvement in case of malignant mesothelioma. PMID:28242997
Eosinophilic Mucin Otomastoiditis and Otopolyposis: A Progressive Form of Eosinophilic Otitis Media.
Azadarmaki, Roya; Westra, William; Prasad, Sanjay
2015-09-01
The purpose of this study is to introduce and define a disease entity on a continuum of eosinophilic otitis media: eosinophilic mucin otomastoiditis and otopolyposis. A case of a 66-year-old woman with complicated chronic otitis media is reported. A literature review of the National Library of Medicine's online database, with a focus on eosinophilic otitis media and eosinophilic mucin rhinosinusitis, was performed. The authors report the case of a 66-year-old woman with a history of asthma, chronic rhinosinusitis, nasal polyposis, and chronic otitis media who presented with allergic middle ear mucin and otic polyps. Treatment involved a tympanomastoidectomy with removal of otic polyps and steroid therapy. Eosinophilic mucin otomastoiditis with otopolyposis is a disease entity on a continuum of eosinophilic otitis media. This disease process shares similarities with eosinophilic mucin rhinosinusitis. Otic polypectomy and steroids are suggested therapeutic measures. © The Author(s) 2015.

Spontaneous pneumomediastinum is a rare entity, predominantly described in young man. The association of acute dyspnea, chest pains and subcutaneous emphysema is usually reported. We report the observation of a pneumomediastinum, fortuitously discovered in front of an isolated giant subcutaneous emphysema in a 59 year old man. The recent clinical history was only marked by the presence of intense and acute dental pains. Associated with a pneumoperitoneum, a retro-pneumoperitoneum, this clinical presentation is uncommon and differs from previous published case reports. Despite a complete evaluation of classical risk factors, its origin remains uncertain. However, the presence of huge dental injuries led to consider such local origin, facilitating air diffusion. This case report allows to reconsider spontaneous pneumomediastinum entity and to propose additional physiopathological mechanisms. This original description underlines the interest to systematically perform dental examination in the presence of unexplained pneumomediastinum.
Segmental stiff skin syndrome (SSS): A distinct clinical entity.
Myers, Kathryn L; Mir, Adnan; Schaffer, Julie V; Meehan, Shane A; Orlow, Seth J; Brinster, Nooshin K
2016-07-01
Stiff skin syndrome (SSS) is a noninflammatory, fibrosing condition of the skin, often affecting the limb girdles. We present 4 new patients with SSS with largely unilateral, segmental distribution. To date, reported cases of SSS have been grouped based on generally accepted clinical and histopathologic findings. The purpose of this study was to analyze differences in clinical and histopathologic findings between previously reported SSS cases. This is a retrospective review of 4 new cases and 48 previously published cases of SSS obtained from PubMed search. Of 52 total cases, 18 (35%) were segmentally distributed and 34 (65%) were widespread. The average age of onset was 4.1 years versus 1.6 years for segmental versus widespread SSS, respectively. Limitation in joint mobility affected 44% of patients with segmental SSS and 97% of patients with widespread SSS. Histopathologic findings were common between the 2 groups. This was a retrospective study of previously published cases limited by the completeness and accuracy of the reviewed cases. We propose a distinct clinical entity, segmental SSS, characterized by a segmental distribution, later age of onset, and less severe functional limitation. Both segmental SSS and widespread SSS share common diagnostic histopathologic features. Copyright © 2016 American Academy of Dermatology, Inc. All rights reserved.

Energy management in buildings is becoming more transactive. Pacific Northwest National Laboratory and the U.S. Department of Energy Building Technologies Office recently defined innovative use cases wherein market-like mechanisms are used to manage energy within buildings, between buildings, and between buildings and third-party entities, such as power utilities. A next step toward defining a set of transactive use cases in the buildings domain is to carefully diagram the corresponding business cases to capture details of transactions among all stakeholders and their economic value propositions. The principles of e3-value diagramming are applied in this report toward creating business value diagrams. Thesemore » principles are extended to be consistent with Universal Modeling Language use-case diagrams. Example diagrams are presented for a subset of buildings-domain use cases that were introduced in an earlier Pacific Northwest National Laboratory report. The diagrams are intended to clearly represent an understanding of the transactions through which individual entities accumulate value in their respective use cases, and the diagrams should therefore support economic valuation studies. The report reviews some of the foundational principles of e3 value and includes authors’ insights concerning the formulation of these diagrams using Universal Modeling Language as a more systematic modeling approach.« less
Acute Splenic Sequestration Crisis in Adult Sickle Cell Disease: A Report of 16 Cases.
Naymagon, Leonard; Pendurti, Gopichand; Billett, Henny H
2015-01-01
Acute splenic sequestration crisis (ASSC), characterized by rapidly progressive anemia and circulatory compromise in the setting of sudden splenic enlargement, is an uncommon entity among adult sickle cell patients. We reviewed cases of adult ASSC encountered at our institution to generate insight into the recognition, diagnosis, and treatment of the condition. Cases of adult ASSC during a 10-year period were identified retrospectively. Patient charts were reviewed for laboratory and imaging results; demographic data and clinical course were collected and reviewed. Sixteen cases of adult ASSC were identified. Most patients presented with pain crisis; only four of 16 patients presented with abdominal pain. The maximum decreases in hemoglobin (Hb) (42.0%) and platelets (62.1%) occurred at day 2.9, delaying identification and treatment. Hemodynamic instability played a large role in dictating risk stratification. Therapy consisted of transfusion (14/16) and splenectomy (5/16). No recurrences were noted in a mean follow-up time of 5.3 years but review of patients' charts demonstrated that at least one of the patients had two prior episodes. Adult ASSC may present with non specific findings and patients may not deteriorate until several days into a previously uneventful hospital course. Changes in platelet counts may be more reliable markers than changes in Hb level since red cell transfusions may interfere with assessments of the sequestration process. This case series of adult ASSC, the largest reported in the literature to date, highlights common clinical, laboratory, radiological, and pathological features of this uncommon entity and helps to guide recognition, diagnosis, and treatment.

Leptomeningeal dissemination in children is typical of high-grade, and occasionally low-grade, neoplasms. Rare cases of widely disseminated oligodendroglia-like leptomeningeal tumors, sometimes with associated spinal cord lesions, have been described that respond to treatment and follow an indolent course. Whether these lesions represent an established tumor category or are a unique entity remains to be established. We present 9 pediatric cases of such diffuse leptomeningeal neuroepithelial tumors (DLNT), 8 with assessment of 2 common genetic alterations seen in oligodendrogliomas, 1p and 19q chromosomal deletions and isocitrate dehydrogenase-1 (IDH1) R132H mutations. Four patients were male and 5 female, with a mean age at presentation of 4 years (range, 2 to 7 y). All presented with signs of increased intracranial pressure and diffuse contrast enhancement of the leptomeninges by magnetic resonance imaging. Three had a cervical or upper thoracic spinal cord tumor, and another had a small cerebellar lesion. Leptomeningeal biopsies showed a thickened and fibrotic arachnoid infiltrated by monotonous cells with round nuclei and prominent perinuclear clearing. All cases were strongly immunoreactive for S100 protein, and most showed faint granular synaptophysin reactivity. Six of 8 cases showed deletions of chromosome arm 1p by fluorescence in situ hybridization, 2 of which also had loss of 19q. None of the lesions reacted with IDH1-R132H antibodies. Although the clinicopathologic features show overlap of these DLNT lesions with oligodendroglioma and extraventricular neurocytoma, they do not exactly match either one, suggesting that DLNTs are a distinct tumor entity.

Spontaneous renal hemorrhage associated with renal tumors.
Mydlo, J H; Kaplan, J; Thelmo, W; Macchia, R J
1997-01-01
Spontaneous ruptures of the kidney sometimes require emergency surgery, at which time the etiology for the rupture becomes evident. Because the patient with previously existing renal pathology is asymptomatic, when these ruptures do occur one should be suspect of underlying disease. We present a case and discuss the relevant aspects of such entities.

Orofacial granulomatosis is a relapsing nonnecrotizing granulomatous syndrome that classically presents with lip and perioral swelling. Over the years, several patients have been referred to the Duke Eye Center Oculoplastics Department for severe, progressive, recurrent eyelid swelling interfering with both their functional vision and their appearance. In this IRB approved retrospective case series, we describe the clinical course of 5 such patients, including their presenting symptoms, diagnosis, and response to treatment. We hope that oculoplastics specialists will consider this entity in the differential diagnosis of periorbital edema and consider initiating localized anti-inflammatory treatment once the diagnosis has been made.
Atypical Presentations of Methemoglobinemia from Benzocaine Spray
Suwantarat, Nuntra; Vierra, Joseph R; Evans, Samuel J
2011-01-01
Widely used for local anesthesia, especially prior to endoscopic procedures, benzocaine spray is one of the most common causes of iatrogenic methemoglobinemia. The authors report an atypical case of methemoglobinemia in a woman presenting with pale skin and severe hypoxemia, after a delayed repeat exposure to benzocaine spray. Early recognition and prompt management of methemoglobinemia is needed in order to lessen morbidity and mortality from this entity. PMID:22162610

We present a case of an extremely rare and relatively new tumor entity of the kidney, the anaplastic sarcoma. Although of unknown origin and pathogenesis, treating such a tumor as if it was anaplastic Wilms' tumor seems to be the only therapeutic solution at the present time. Newer immunohistochemical staining and molecular probes should be applied to this neoplasm in order for us to understand it nature and maximize therapy. PMID:19219373

2015-01-01
Intraosseous pneumatocyst is a benign, gas-filled, cystic lesion, and is commonly encountered in iliac bone or sacrum. Other locations of this lesion following trauma are rare, and only a handful of isolated cases have been reported. The pathogenesis and etiologies of this uncommon entity are various and it can present a diagnostic challenge. Only four previous cases have described the natural course of intravertebral pneumatocysts. Here, the authors report a rare case of traumatic pneumatocyst, which resolved rapidly without further complication. Possible pathogenic mechanisms are discussed and reviews of literatures are included. PMID:26217389

Langerhans cell histiocytosis (LCH) of the vulva is rare and even moreso in postmenopausal women. Twenty-six cases of primary vulvar LCH have been described in the current literature, and only 8 cases are in postmenopausal women. We report an additional case of primary vulvar LCH in a 59-yr-old woman with subsequent multiorgan involvement. In this article, we briefly describe the clinical presentation, histopathological findings, and immunohistochemistry results of vulvar LCH. We want to emphasize the importance of recognizing this entity in a woman with vulvar lesions both for the clinician and the pathologist.
Barium appendicitis after upper gastrointestinal imaging.
Novotny, Nathan M; Lillemoe, Keith D; Falimirski, Mark E
2010-02-01
Barium appendicitis (BA) is a rarely seen entity with fewer than 30 reports in the literature. However, it is a known complication of barium imaging. To report a case of BA in a patient whose computed tomography (CT) scan was initially read as foreign body ingestion. An 18-year-old man presented with right lower quadrant pain after upper gastrointestinal imaging 2 weeks prior. A CT scan was obtained of his abdomen and pelvis that revealed a finding that was interpreted as a foreign body at the area of the terminal ileum. A plain X-ray study of the abdomen revealed radiopaque appendicoliths. Pathology confirmed the diagnosis of barium appendicitis. BA is a rare entity and the pathogenesis is unclear. Shorter intervals between barium study and presentation with appendicitis usually correlate with fewer complications. Copyright (c) 2010 Elsevier Inc. All rights reserved.

Complication of dental infections might be various and heterogeneous. The most common complications are represented by maxilar celulitis, canine space celulitis, infratemporal space celulitis, temporal celulitis and bacteremia. Among rarest complications we found: sepsis, bacterial endocarditis, mediastinitis, intracranial complications, osteomyelitis, etc. Although dental infections are often considered trivial entities, sometimes they can reach an impressive gravity. In this regard, the present study describes a case of dental infection complicated by meningitis, subdural empiema and cerebral vasculitis. Furthermore, we observed other neurological complications, like thalamic ischemic infarction, during the disease evolution. Noteworthy, these entities were not presented when the patient was admitted to hospital. Therefore, the main aim of this report is to highlight the serious consequences that an infection of dental origin could cause. Key words: Meningitis, subdural empyema, odontogenic infections.

Subareolar abscess of the male breast is a rare condition, which can be complicated by a fistula from the areolar skin into a lactiferous duct. In 1951, Zuska et al first characterised this entity in women. Literature on mammillary fistulas in men is scarce and therefore standardisation of treatment does not exist. We present two cases of recurrent subareolar abscesses with draining fistulas. Both patients were successfully treated by complete excision of the lactiferous duct fistula, and continue to do well with no evidence of disease recurrence. When male patients present with a draining subareolar abscess, one should have a high index of suspicion for a mammillary fistula. Failure to identify and surgically excise the fistula may lead to recurrence of the abscess and prolonged morbidity. The most effective management of this uncommon entity includes complete excision of the lactiferous duct fistula. PMID:24706699

2017-03-01
Numerical abnormalities of mitral leaflets is a special entity in congenital mitral malformations. Previously reported cases of uni-leaflet mitral valve were primarily related to absence or dysplasia of certain leaflets. We present a case here with mitral leaflets that were not divided into anterior and posterior as usual, but developed as an integral structure instead, which is different from previously documented cases of uni-leaflet mitral valves. Real time three-dimensional echocardiography (RT3DE) provides a visual presentation of the abnormal mitral structure which was confirmed by surgical operation. To the best of our knowledge, this unusual form of uni-leaflet mitral valve has not been reported yet. © 2017, Wiley Periodicals, Inc.
Connectivity-based, all-hexahedral mesh generation method and apparatus
Tautges, T.J.; Mitchell, S.A.; Blacker, T.D.; Murdoch, P.
1998-06-16
The present invention is a computer-based method and apparatus for constructing all-hexahedral finite element meshes for finite element analysis. The present invention begins with a three-dimensional geometry and an all-quadrilateral surface mesh, then constructs hexahedral element connectivity from the outer boundary inward, and then resolves invalid connectivity. The result of the present invention is a complete representation of hex mesh connectivity only; actual mesh node locations are determined later. The basic method of the present invention comprises the step of forming hexahedral elements by making crossings of entities referred to as ``whisker chords.`` This step, combined with a seaming operation in space, is shown to be sufficient for meshing simple block problems. Entities that appear when meshing more complex geometries, namely blind chords, merged sheets, and self-intersecting chords, are described. A method for detecting invalid connectivity in space, based on repeated edges, is also described, along with its application to various cases of invalid connectivity introduced and resolved by the method. 79 figs.

2005-01-01
Early detection and treatment of breast cancer, leading to longer survival, has revealed the natural history of this disease process. Linitis plastica of the stomach is a potential long-term sequela of metastatic breast cancer. Here we present a case of metastatic breast cancer presenting as linitis plastica, as well as the treatment algorithm for this rare clinical entity. The world literature describes a clear pattern of linitis plastica for metastatic infiltrating lobular breast cancer and a discrete nodular pattern for infiltrating ductal cancer, in regard to metastasis to the stomach. To our knowledge, this is the first case of infiltrating ductal cancer presenting as linitis plastica of the stomach.

Esophageal intramural pseudodiverticulosis is a rare pathology whose etiology is unknown, but which is frequently associated with three highly prevalent entities: esophageal reflux disease, esophageal candidosis and alcoholic esophagitis. With conservative treatment the course of these pathologies is usually benign. However, some severe cases are resistant to conservative treatment and may require more aggressive management. We here present the case of patient suffering from a severe esophagitis complicated by chronic mediastinitis with life-threatening repercussions, requiring esophagectomy as treatment.
Solid pseudopapillary tumor of the pancreas: case report and literature review.
Camacho-Aguilera, José Francisco; Romero-Mejía, César; Valenzuela-Espinoza, Alfonso

Solid pseudopapillary tumor of the pancreas is an epithelial tumor of low malignancy that primarily affects young women and represents approximately 1-2% of all pancreatic neoplasms. We present a case of this type of tumor treated in the General Hospital of Tijuana, Mexico, as well as a review of the literature. We present the case of a 37-year-old female with symptomatology of early satiety and abdominal distension. During open cholecystectomy we found a tumor in the body of the pancreas. Biopsy was done, establishing the diagnosis of solid pseudopapillary tumor of the pancreas. The patient was treated successfully with distal pancreatectomy and splenectomy. Solid pseudopapillary tumor of the pancreas is a rare neoplasm. It is more frequent in young women and has an unknown etiology. Clinical manifestations include abdominal pain, sensation of plenitude or early satiety, abdominal mass, nausea and vomiting. Laboratory tests are usually normal. Computerized axial tomography may show a large encapsulated heterogeneous mass. Diagnosis is established through biopsy and surgery is the best treatment for this pathological entity. One may conclude that the solid pseudopapillary tumor is a differential diagnosis in the presence of pancreatic tumors, although due to its rarity it is not the first option to discard. Surgery represents the best treatment for this pathological entity and should be attempted in all cases, independent of the size of the pancreatic injury.

Guillain-Barré syndrome and myasthenia gravis both lead to muscle weakness but the two combined is uncommon. Detection of these entities can help identify forms of autoimmune neuromuscular diseases that may respond to immunotherapy. This report sought to characterize the clinical features of these two entities when combined. This report is of a case of combined Guillain-Barré syndrome and myasthenia gravis. The clinical features were analyzed and correlated to those published in English literature from 1960 to 2012. Ten reports and 12 cases, including the present case, were reviewed. There were 12 patients (4 women and 8 men), aged 17 to 84 years, with combined Guillain-Barré syndrome and myasthenia gravis. Four had post-infectious Guillain-Barré syndrome followed by the development of myasthenia gravis concurrently or concomitantly within one month. All cases had symptoms of ptosis and areflexia. The other common presentations were limb weakness, oculobulbar weakness, and respiratory involvement. Functional outcome was mentioned in 10 patients and seven had good outcome (Hughes scale ≤ 2). Detection of ptosis with or without ophthalmoplegia, distribution of limb weakness, and reflex can help in recognizing combined Guillain-Barré syndrome and myasthenia gravis. The early recognition of this combination of peripheral nervous and neuro-muscular junction inflammation is important for initial treatment and prognosis.

The name epidermal nevus syndrome could be applied to a group of clinically and histopathologically different entities as has been pointed out by Happle. Phacomatosis pigmentokeratotica is a further type of epidermal nevus syndrome distinguished by the presence of a sebaceous nevus and a contralateral speckled lentiginous nevus of the papular type, associated with skeletal or neurological abnormalities. Three new cases of this recently delineated syndrome are presented. A common origin may account for the temporal and spatial relationship between the epidermal and the speckled lentiginous nevus. The concept of melanocytic-epidermal twin spotting similar to the interpretation of vascular twin spotting could explain the pathogenesis of this entity.
Dupuytren in a Child: Rare Presentation of a Rare Clinical Entity.
Spyropoulou, Georgia-Alexandra; Pavlidis, Leonidas; Milothridis, Panagiotis; Zaraboukas, Thomas; Demiri, Efterpi
2016-12-01
Dupuytren disease in children younger than 10 years is rare and only 8 histologically proven cases have been reported. A histologically proven Dupuytren disease in a 10-year-old with an uncommon clinical presentation as a nodule on the radial side of the middle phalanx of the little finger is documented. Dupuytren's disease should be in the differential diagnosis in cases of nodules and contractures in the palm and fingers of children. Copyright © 2016 American Society for Surgery of the Hand.

Solitary bone metastasis to fibula in patients of lung carcinoma is a rare entity, with only four cases reported in literature. We, hereby, present a case of a 50 year-old-male who was given three cycles of chemotherapy for lung carcinoma with no distant metastasis but presented 2 months later with a fusiform, painful swelling around the knee that was clinically suspected to be inflammatory in nature but proved to be fibular metastasis on cytology. There was no evidence of skeletal metastasis on initial bone scan. He was given palliative radiotherapy for this with symptomatic relief. PMID:28469322

De Garengeot's hernia: our experience of three cases and literature review
Akbari, Khalid; Wood, Claire; Hammad, Ahmed; Middleton, Simon
2014-01-01
Groin hernia is a common surgical presentation and nearly half of the femoral hernias present acutely with strangulation. The hernia sac usually contains omentum or small bowel. Rarely, the appendix can herniate into the femoral canal. De Garengeot's hernia is the term used to describe the presence of appendicitis in the femoral hernia. Hernia explorations are performed by surgical trainees and encountering a De Garengeot's hernia can be challenging to manage. We report our experience of three cases of this rare entity and a literature review to improve our understanding for optimum management. PMID:25080546

Background First branchial cleft anomalies (FBCA) are rare clinical entities of the head and neck. Typically, the tract of the FBCA begins in the external auditory canal and ends in the postauricular or submandibular region. Case Presentation We present a case of a 23-year-old man who had a first branchial cleft fistula with atypical opening on the root of the helical crus. Complete excision of the tract, including the cuff of surrounding cartilage, was performed. Histopathology revealed a fistular tract lined with squamous epithelium. To our knowledge, this is the first case to be reported of type I FBCA with an opening on the root of the helical crus. The low incidence and varied presentation often result in misdiagnosis and inappropriate treatment. Conclusions In the patients with FBCA, careful recognition of atypical variants is essential for complete excision. PMID:29560006
Susac syndrome: the first case report in Peru.
Rivadeneira-Sotelo, Carolina; Meza Vega, María; Segura-Chávez, Darwin; Castro-Suarez, Sheila
2017-08-30
Susac Syndrome is a rare entity, characterized by a triad of subacute encephalopathy, retinal artery occlusion and sensorineural hearing loss. It is more common in women and the age of onset fluctuates between 9-58 years of age. The pathogenesis is presented as microangiopathic changes at the cerebral, retinal and cochlear levels associated with an autoimmune mechanism. We present the case of a 31-year-old woman who started with a diffuse headache, puerile behavior, bradylalia and somnolence. As the disease progressed, she had auditory deficit and arterial obstruction of the right temporal retinal branch in retinal fluorescein angiography. Brain magnetic resonance showed rounded hyperintense lesions in the corpus callosum, periventricular region and cerebellum. This is the first reported case of Susac Syndrome in Peru, presented with the classic triad, which is an infrequent presentation. However, cases that show incomplete forms should be evaluated in a timely manner to initiate timely treatment and avoid irreversible consequences.

Intelligence analysts demand rapid information fusion capabilities to develop and maintain accurate situational awareness and understanding of dynamic enemy threats in asymmetric military operations. The ability to extract relationships between people, groups, and locations from a variety of text datasets is critical to proactive decision making. The derived network of entities must be automatically created and presented to analysts to assist in decision making. DECISIVE ANALYTICS Corporation (DAC) provides capabilities to automatically extract entities, relationships between entities, semantic concepts about entities, and network models of entities from text and multi-source datasets. DAC's Natural Language Processing (NLP) Entity Analytics model entities as complex systems of attributes and interrelationships which are extracted from unstructured text via NLP algorithms. The extracted entities are automatically disambiguated via machine learning algorithms, and resolution recommendations are presented to the analyst for validation; the analyst's expertise is leveraged in this hybrid human/computer collaborative model. Military capability is enhanced by these NLP Entity Analytics because analysts can now create/update an entity profile with intelligence automatically extracted from unstructured text, thereby fusing entity knowledge from structured and unstructured data sources. Operational and sustainment costs are reduced since analysts do not have to manually tag and resolve entities.

Presence of voltage-gated potassium channel complex antibody in a case of genetic prion disease
Jammoul, Adham; Lederman, Richard J; Tavee, Jinny; Li, Yuebing
2014-01-01
Voltage-gated potassium channel (VGKC) complex antibody-mediated encephalitis is a recently recognised entity which has been reported to mimic the clinical presentation of Creutzfeldt-Jakob disease (CJD). Testing for the presence of this neuronal surface autoantibody in patients presenting with subacute encephalopathy is therefore crucial as it may both revoke the bleak diagnosis of prion disease and allow institution of potentially life-saving immunotherapy. Tempering this optimistic view is the rare instance when a positive VGKC complex antibody titre occurs in a definite case of prion disease. We present a pathologically and genetically confirmed case of CJD with elevated serum VGKC complex antibody titres. This case highlights the importance of interpreting the result of a positive VGKC complex antibody with caution and in the context of the overall clinical manifestation. PMID:24903967

In 2005, the combined pulmonary fibrosis and emphysema (CPFE) was first defined as a distinct entity, which comprised centrilobular or paraseptal emphysema in the upper pulmonary lobes, and fibrosis in the lower lobes accompanied by reduced diffused capacity of the lungs for carbon monoxide (DLCO). Recently, the fibrosis associated with the connective tissue disease was also included in the diagnosis of CPFE, although the exposure to tobacco, coal, welding, agrochemical compounds, and tire manufacturing are the most frequent causative agents. This entity characteristically presents reduced DLCO with preserved lung volumes and severe pulmonary hypertension, which is not observed in emphysema and fibrosis alone. We present the case of a 63-year-old woman with a history of heavy tobacco smoking abuse, who developed progressive dyspnea, severe pulmonary hypertension, and cor pulmonale over a 2-year period. She attended the emergency facility several times complaining of worsening dyspnea that was treated as decompensate chronic obstructive pulmonary disease (COPD). The imaging examination showed paraseptal emphysema in the upper pulmonary lobes and fibrosis in the middle and lower lobes. The echo Doppler cardiogram revealed the dilation of the right cardiac chambers and pulmonary hypertension, which was confirmed by pulmonary trunk artery pressure measurement by catheterization. During this period, she was progressively restricted to the minimal activities of daily life and dependent on caregivers. She was brought to the hospital neurologically obtunded, presenting anasarca, and respiratory failure, which led her to death. The autopsy showed signs of pulmonary hypertension and findings of fibrosis and emphysema in the histological examination of the lungs. The authors highlight the importance of the recognition of this entity in case of COPD associated with severe pulmonary hypertension of unknown cause. PMID:28740835

Subacute subdural hematoma (SASDH) is an entity which is yet to capture the popular imagination among the neurosurgeons. Its management is often equated clinically to that of the chronic subdural hematoma (CSDH). However, their neurological deterioration is usually rapid, which seems to align them with acute subdural hematoma (ASDH). We proceed for their epidemiological evaluation. The advantages of a novel "double barrel technique (DbT)" over the conventional burrhole drainage are also presented. This retrospective study was conducted on all the patients having clinical and radiological evidence of SASDH, admitted to a tertiary care referral institute, during the period August 2013 to December 2015. Postoperatively, patients were followed-up for 3-24 months. 46.87% of the patients belonged to the 35-54 year age group with a male predominance (3.6:1); 68.7% had a history of alcohol abuse, whereas aspirin users were 25%. 87.5% cases were unilateral, 18.75% were hemispheric, and 46.87% were present on the left side. Altered consciousness (100%) followed by headache (37.5%) were the most common presenting clinical features. SASDH is an uncommon neurosurgical entity (0.89% of traumatic brain injury cases in our study) and mimics both CSDH as well as ASDH. The true incidence of SASDH may have been underestimated due to its clinical imitation with CSDH. This study in a South Asian nation also provides the epidemiological data of this rare neurosurgical entity. Outcome of surgery is good; our retrospective study confirms that "DbT" is an adequate and safe treatment. However, a better designed, randomized control trial will be needed to reinforce our findings.

Contribution of one case of non-Hodgkin lymphoma (NHL) with vesical involvement, that presented clinically with urological symptomatology. Vesical involvement is typical of NHL, and is becoming more frequent in association with the increased number of AIDS patients under immunosuppressive therapy. It should be expected that this currently unusual entity will become more common in the future.
Odontogenic keratocyst: a peripheral variant.
Vij, H; Vij, R; Gupta, V; Sengupta, S
2011-01-01
Odontogenic keratocyst, which is developmental in nature, is an intraosseous lesion though on rare occasions it may occur in an extraosseous location. The extraosseous variant is referred to as peripheral odontogenic keratocyst. Though, clinically, peripheral odontogenic keratocyst resembles the gingival cyst of adults, it has histologic features that are pathognomonic of odontogenic keratocyst. This article presents a case of this uncommon entity.

Gene fusions of EWSR1 with members of the CREB family of transcription factors (CREB1, ATF1, and CREM) have recently been described in exceptional intracranial myxoid mesenchymal tumors. Although this is a known gene fusion found in various mesenchymal tumors, EWSR1 fusion with CREM has only been observed in 3 intracranial myxoid tumors. In this paper, we present 1 such tumor with in-depth histopathological description and long-term follow-up. There is controversy regarding whether these tumors represent a novel entity or simply an intracranial localization of the myxoid variant of angiomatoid fibrous histiocytoma, a rare soft tissue tumor of the extremities. Out of 11 cases mentioned in the literature, the 3 isolated case reports by Dunham et al, Ochalski et al, and Alshareef et al are designated as angiomatoid fibrous histiocytoma, whereas the others are defined as a novel tumoral entity called intracranial myxoid mesenchymal tumor with EWSR1-CREB fusion. We believe the vast morphological and immunohistochemical spectrum of angiomatoid fibrous histiocytoma makes it difficult to dismiss this diagnosis.
Primary tuberculous petrositis.

Tuberculous osteomyelitis of the temporal bone is a rare and dangerous entity that should be included in the differential diagnosis of infectious processes of the base of the skull. We present the case of an 11-year-old child who presented with diplopia, ear discharge and hearing loss. The radiological and histopathological findings revealed tuberculous otitis with osteomyelitis and an abscess in the petrous apex. The child responded to anti-tuberculous chemotherapy. The diagnosis and management of tuberculous osteomyelitis are discussed and a brief review of the literature is presented.

We present a case of florid cemento-osseous dysplasia occurring in a 20-year-old Indian woman. The subject presented with three lesions involving the maxillary right quadrant, maxillary left quadrant and mandibular left quadrant. The mandibular left quadrant also demonstrated a cyst.The diagnosis was made by correlating the clinical presentation with that of the radiological and histopathological findings. This is a rare entity because of an unusual combination of Asian race along with the association of dentigerous cyst.

Esophago-pleural fistula (EPF) is an uncommon condition, despite of an anatomical proximity of these structures. Causes of EPF include pneumonectomy for suppurative or tubercular disease of lung and carcinoma lung, malignancy of esophagus. Benign EPF is rare and may be due to trauma or infection. The most common infectious cause is tuberculosis. Spontaneous development of fistula between esophagus and pleura is rarely described in literature. We, hereby present a spontaneous case of such a rare entity in a middle-aged male.

2000-01-01
Chemically induced avascular necrosis of bone is a well documented entity. Indomethacin is one of the causes of this condition but is often difficult to recognise. Review of the literature shows that only one case of indomethacin induced avascular necrosis has been reported in the English language between 1966 and the present. The case of a young healthy man, who developed avascular necrosis of head of femur after prolonged administration of indomethacin, is reported here.

Juvenile granulosa cell tumor of testis: case report and review of literature.
Dudani, Rajesh; Giordano, Lisa; Sultania, Priyanka; Jha, Kamlesh; Florens, Adrian; Joseph, Tessy
2008-04-01
Juvenile granulosa cell tumor (JGCT) of testis is extremely rare in childhood. It is considered a benign entity because metastasis has never been reported. Testicular-sparing surgery is the recommended treatment. We reported this case in a newborn who presented with unilateral scrotal swelling. Histopathology and immunohistochemistry confirmed JGCT. Follow-up at 6 months after surgery did not show any recurrence. Even though JGCT is very rare in childhood, it is one of the important differentials of newborn scrotal mass.

A factitious disorder (FD) is a diagnostic entity in which patients intentionally act physically or mentally ill without obvious benefits and without being consciously aware of a clear underlying motive. Most pediatric FD cases have been reported as Munchausen syndrome by Proxy; however, pediatric disease symptoms can also be intentionally falsified by child and adolescent patients. To our knowledge, in the medical literature, an FD patient presenting with stuttering has not been previously reported. In this case report, we aimed to discuss the diagnosis and treatment process of FDs in children and adolescents by reporting the cases of two FD patients presenting with stuttering according to the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition. Both patients improved with psychoeducation and early confrontation.

Papillary tumor of the pineal region (PTPR) is a newly recognized distinct entity in the 2007 World Health Organization nomenclature. This tumor is characterized by epithelial-appearing areas with papillary features and more densely cellular areas that often display ependymal-like differentiation. Ultrastructurally, this rare neuroepithelial tumor possesses neuroendocrine, secretory, and ependymal organelles that likely originate from the subcommissural organ (SCO) near the aqueduct of Sylvius. To date, approximately fifty-seven described cases worldwide have been recognized, with ages ranging from 5 years to 66 years (mean age=32 years). Clinical presentation most often includes headache and obstructive hydrocephalus. The tumor, which is well circumscribed, may be cystic and radiographically is often considered to be consistent with the findings of a pineocytoma. Microscopic evaluation often demonstrates a lesion with papillary areas lined by epithelioid tumor cells with eosinophilic cytoplasm and more cellular areas with cells exhibiting clear or vacuolated cytoplasm. Perivascular and true rosettes may be identified. Distinctive immunohistochemical features including reactivity for keratins (AE1/AE3, CAM 5.2, CK18) and only focal GFAP staining help distinguish this neoplasm from an ependymoma. The relative paucity of data compiled for this tumor makes giving an accurate diagnosis and prognosis a daunting task. We discuss two additional cases of PTPR that presented to us within a three-month span in order to more fully elucidate the possible presentations of this rare entity. Furthermore, we examine now 59 reported cases of PTPR in order to review the current diagnostic and treatment modalities in addition to exploring emerging research encompassing this unusual neoplasm.
Scalp Metastasis as the First Sign of Small-Cell Lung Cancer: Management and Literature Review
Salemis, Nikolaos S.; Veloudis, Georgios; Spiliopoulos, Kyriakos; Nakos, Georgios; Vrizidis, Nikolaos; Gourgiotis, Stavros
2014-01-01
Cutaneous metastasis from primary visceral malignancy is a relatively uncommon clinical entity, with a reported incidence ranging from 0.22% to 10% among various series. However, the presence of cutaneous metastasis as the first sign of a clinically silent visceral cancer is exceedingly rare. We describe here a case of an asymptomatic male patient who presented with a solitary scalp metastasis as the initial manifestation of an underlying small-cell lung cancer. Diagnostic evaluation revealed advanced disease. We conclude that the possibility of metastatic skin disease should always be considered in the differential diagnosis in patients with a history of smoking or lung cancer presenting with cutaneous nodules. Physicians should be aware of this rare clinical entity, and appropriate investigation should be arranged for early diagnosis and initiation of the appropriate treatment. The prognosis for most patients remains poor. PMID:25058760

The aim of this article is to report our experience in the diagnosis of two cases of iliac artery endofibrosis or arteriopathy, a rare entity occurring in high-performance athletes, presenting with intermittent claudication (right-sided in both) after maximal exercise. External iliac artery endofibrosis or arteriopathy is a likely diagnosis in competitive athletes free of cardiovascular risk factors who present with leg claudication. Arteriography and a papaverine-assisted mean pressure gradient across the iliac arteries of more than 10 mmHg is a useful diagnostic approach. Moreover, balloon angioplasty of the iliac artery in that patient, in whom a pressure gradient was detected,more » resulted in symptomatic relief for 2 months followed by mild symptom recurrence. Thus, although balloon angioplasty is feasible and safe, it might not be adequate to treat this entity and, thus, its value remains undefined.« less

Palisaded neutrophilic and granulomatous dermatitis and interstitial granulomatous dermatitis are uncommon granulomatous dermatoses that often arise in association with rheumatoid arthritis. These 2 entities have overlapping features and may exist on a spectrum. We report an intriguing case of a 53-year-old man with advanced rheumatoid arthritis who presented with a large indurated painful truncal plaque with a palpable cord in addition to a papulonodular eruption on his dorsal hands. Furthermore, our patient had a recurrence in a near-identical mirror-image pattern on the contralateral trunk. The constellation of clinical and histopathological findings in our patient further suggests that palisaded neutrophilic and granulomatous dermatitis and interstitial granulomatous dermatitis exist as overlapping disease entities on a continuum. In addition, we propose that recurrence of skin findings may be indicative of the severity of the underlying systemic disease process.
Gastric Volvulus with Segmental Necrosis Treated with Wedge Resection and Gastrogastrostomy.
Merz, Alexa Elizabeth; Preston, Jennifer Francis
2017-12-01
Ischemic necrosis is a feared complication of acute gastric volvulus, occurring in 11% of patients presenting with the condition and responsible for mortality in 30%. In such cases, there are few well-validated options for surgical reconstruction. We present the case of a 77-year-old woman with intraabdominal mesenteroaxial gastric volvulus with segmental ischemic gastric necrosis who underwent wedge gastrectomy and hand-sewn gastrogastrostomy. She did well postoperatively and experienced no significant gastrointestinal complications. Gastric wedge resection with gastrogastrostomy presents a novel surgical intervention for a rare and highly morbid entity. We hope to add it to the repertoire of surgeons facing acute gastric volvulus complicated by segmental necrosis.
Interactive entity resolution in relational data: a visual analytic tool and its evaluation.
Kang, Hyunmo; Getoor, Lise; Shneiderman, Ben; Bilgic, Mustafa; Licamele, Louis
2008-01-01
Databases often contain uncertain and imprecise references to real-world entities. Entity resolution, the process of reconciling multiple references to underlying real-world entities, is an important data cleaning process required before accurate visualization or analysis of the data is possible. In many cases, in addition to noisy data describing entities, there is data describing the relationships among the entities. This relational data is important during the entity resolution process; it is useful both for the algorithms which determine likely database references to be resolved and for visual analytic tools which support the entity resolution process. In this paper, we introduce a novel user interface, D-Dupe, for interactive entity resolution in relational data. D-Dupe effectively combines relational entity resolution algorithms with a novel network visualization that enables users to make use of an entity's relational context for making resolution decisions. Since resolution decisions often are interdependent, D-Dupe facilitates understanding this complex process through animations which highlight combined inferences and a history mechanism which allows users to inspect chains of resolution decisions. An empirical study with 12 users confirmed the benefits of the relational context visualization on the performance of entity resolution tasks in relational data in terms of time as well as users' confidence and satisfaction.

This Perspective addresses ambiguities in designations of "new drugs" intended as new therapeutic entities (NTEs). Designation of an NTE as a new drug is significant, as it may confer regulatory exclusivity, an important incentive for development of novel compounds. Such designations differ between jurisdictions according to their drug laws and drug regulations. Chemical, biological, and innovative drugs are addressed in turn. The terms new chemical entity (NCE), new molecular entity (NME), new active substance (NAS), and new biological entity (NBE) as applied in worldwide jurisdictions are clarified. Differences between them are explored through case studies showing why new drugs have different periods of exclusivity in different jurisdictions or none at all. Finally, this Perspective recommends that in future, for the purpose of new drug compilations, NME is used for a new chemical drug, NBE for a new biological drug, and the combined designation NTE should refer to either an NME or an NBE.
Granulomatous mastitis caused by histoplasma and mimicking inflammatory breast carcinoma.
Osborne, B M
1989-01-01
Two cases of a lobular, necrotizing granulomatous process causing a unilateral painful breast mass mimicking carcinoma are presented for comparison. While the morphologic appearance in each case was that of lobular granulomatous mastitis, the etiologic agent in one case appeared to be Histoplasma capsulatum, based on Grocott methenamine silver staining, and represents the second reported case of histoplasmosis involving only breast parenchyma. Awareness of the rare entity, granulomatous mastitis, is important for the pathologist because the definitive diagnosis is made microscopically. Thorough evaluation of the breast tissue is essential for its management and should eventually contribute to the clarification of its etiology.

Three cases are described presenting with progressive contractures in whom the muscles felt firm and `woody' and a clinical diagnosis of myosclerosis was made in each case. A patient and his young sister were shown to be suffering from spinal muscular atrophy with superimposed, excessive proliferative activity of fibroblasts, and in these cases a beneficial effect of penicillamine was demonstrated. The third case with a clinical picture of myosclerosis was found on muscle biopsy to have extensive inflammatory infiltration of the connective tissue, and responded temporarily at least to high doses of corticosteroids. It is emphasized that several different disease entities can give rise to this clinical picture. Images PMID:4793163

Suppurative parotitis is an uncommon entity identified in newborns. While Staphylococcus aureus has been frequently identified as the causative pathogen among the few patients diagnosed with neonatal suppurative parotitis (NSP), there has only been one prior case described in the literature that was due to methicillin-resistant Staphylococcus aureus (MRSA). Because of its virulence, MRSA presents new and substantial challenges for the surgeon; we describe two cases of NSP caused by MRSA and the subsequent surgical intervention necessitated for cure. We also include a review of all cases of NSP described in the English-language literature.

Arifin, Muhammad Z.; Yudoyono, Farid; Dahlan, Rully H.; Hernowo, Bethy S.; Sutiono, Agung B.; Faried, Ahmad
2014-01-01
Background: Giant dermatofibrosarcoma protuberans (DFSP) of the scalp is a rare case, which is an intermediate grade soft tissue neoplasm originating from the dermal layer of the skin, which usually occurs in adults. Case Description: We describe such a case in a 26-year-old male. A wide local excision of the tumor with a generous tissue margin was performed; microscopic and immunohistochemical findings established the diagnosis of recurrent DFSP. Conclusion: Our case is unique in that it is presented as a dermatofibrosarcoma protuberans of the scalp, which is an extremely rare clinical entity, and the patient remains well after 14 months with no further treatment, without any tumor recurrence.

2017-01-01
Gender dysphoria is a new entity introduced in the Diagnostic and Statistical Manual of Mental Disorder V to address the distress of the previously labeled gender identity disorder patients. It is less commonly seen in natal females, often starting in their childhood. Adults and adolescent natal females with early-onset gender dysphoria are almost always gynephilic. This case report is presented to discuss the interesting evolution of the symptoms in gender dysphoria case with difficulties in adjusting to the assigned sexual role, relationship problems, morbid jealousy, and severe depressive features with suicidal ideations.

2014-01-01
Non-traumatic perforations of the bile ducts are unfrequently encountered entities, all the more when they affect the intrahepatic bile ducts, exteriorizing their biliary content in the great peritoneal cavity. Reporting such a case has determined the authors to perform a careful overview of the cases present in the literature. An observation that can be made based on these is that the obstruction of the main bile duct due to lithiasis determines, by pressure increase, the dilation of the bile system branches, all on the background of an unknown malformation of the intrahepatic bile ducts.

Cryptococcus neoformans is a fungal pathogen associated with advanced HIV disease and other disorders associated with immune dysfunction. The pulmonary and the central nervous system are the most common manifestations of the disease. Localised osteomyelitis as the sole manifestation of extrapulmonary disease is rare. Herein, we present five cases of Cryptococcus osteomyelitis as the only manifestation of extrapulmonary disease. We also identified 84 additional cases of isolated cryptococcal osteomyelitis in the literature. Using these data, we have made some general recommendations regarding an approach to treatment of this uncommon clinical entity. © 2016 Blackwell Verlag GmbH.
Van Wyk Grumbach Syndrome: A Rare Consequence of Hypothyroidism.
Reddy, Pavan; Tiwari, Kritika; Kulkarni, Abhishek; Parikh, Ketan; Khubchandani, Raju
2018-05-19
Long standing hypothyroidism presenting as an ovarian mass has been well described in literature as the Van Wyk Grumbach syndrome (hypothyroidism, isosexual precocious puberty and ovarian mass). Here, authors report this entity in a 11 y 7 mo old girl child who was referred to a surgeon in view of intestinal obstruction along with a multiloculated ovarian cyst. On evaluation, she was found to have raised serum creatinine, short stature, delayed bone age and pituitary enlargement. She was diagnosed with autoimmune thyroiditis and was started on replacement therapy with thyroxine, after which the ovarian cysts regressed. This entity should be kept in mind in cases of ovarian cysts, especially those with isosexual precocity, to prevent unnecessary evaluation and surgical misadventures.
Anti-PIT-1 antibody syndrome; a novel clinical entity leading to hypopituitarism.
Bando, Hironori; Iguchi, Genzo; Yamamoto, Masaaki; Hidaka-Takeno, Ryoko; Takahashi, Yutaka

Various hypothalamic-pituitary diseases cause hypopituitarism. Inflammation related to autoimmunity also causes hypopituitarism. Hypophysitis is a representative disease caused by autoimmunity. Generally, anterior pituitary hormones are non-specifically impaired in this condition, but specific hormone defects have been reported in some cases. Anti-PIT-1 (pituitary-specific transcription factor 1) antibody syndrome is a novel clinical entity that presents an acquired combined pituitary hormone deficiency characterized by a specific defect in growth hormone, prolactin, and thyroid-stimulating hormone. Circulating anti-PIT-1 antibody along with various autoantibodies are detected with multiple endocrine organopathy, meeting the definition of autoimmune polyglandular syndrome. Mechanistically, cytotoxic T lymphocytes that specifically react with PIT-1 protein play an important role in the development of this syndrome.

Background: Vaginal stones are rare and often unknown entities. Most urologists may never see a case in their careers. Case Presentation: We present the case of a 34-year-old bedridden Caucasian woman with mental and physical disabilities who presented with a large primary vaginal calculus, which, surprisingly, had remained undiagnosed until the patient suffered a right renal colic caused by a ureteral stone. The vagina was completely filled and a digital examination was not possible. For this reason, the stone was removed using surgical pliers with some maneuvering. A vesicovaginal fistula was excluded, as well as foreign bodies or other nidi of infection. After, urethral lithotripsy was performed as planned. The postoperative course and follow-up were uneventful. Conclusion: Although vaginal calculi are extremely rare in literature, their differential diagnosis should be considered in women with incontinence and associated disabilities, paraplegia, or prolonged immobilization in recumbent position.
Subacute Sclerosing Panencephalitis of the Brainstem as a Clinical Entity
Yang, Jason; Ciacci, Joseph D.
2017-01-01
Subacute sclerosing panencephalitis (SSPE) is a rare progressive neurological disorder of early adolescence caused by persistent infection of the measles virus, which remains prevalent worldwide despite an effective vaccine. SSPE is a devastating disease with a characteristic clinical course in subcortical white matter; however, atypical presentations of brainstem involvement may be seen in rare cases. This review summarizes reports to date on brainstem involvement in SSPE, including the clinical course of disease, neuroimaging presentations, and guidelines for treatment. A comprehensive literature search was performed for English-language publications with keywords “subacute sclerosing panencephalitis” and “brainstem” using the National Library of Medicine PubMed database (March 1981–September 2017). Eleven articles focusing on SSPE of the brainstem were included. Predominant brainstem involvement remains uncharacteristic of SSPE, which may lead to misdiagnosis and poor outcome. A number of case reports have demonstrated brainstem involvement associated with other intracranial lesions commonly presenting in later SSPE stages (III and IV). However, brainstem lesions can appear in all stages, independent of higher cortical structures. The varied clinical presentations complicate diagnosis from a neuroimaging perspective. SSPE of the brainstem is a rare but important clinical entity. It may present like canonical SSPE or with unique clinical features such as absence seizures and pronounced ataxia. While SSPE generally progresses to the brainstem, it can also begin with a primary focus of infection in the brainstem. Awareness of varied SSPE presentations can aid in early diagnosis as well as guide management and treatment. PMID:29112137

Burkitt lymphoma, is described as an aggressive form of non-Hodgkin lymphoma of B cells which occurs most often in children and young adults, ovarian lymphoma can appear as a primary lesion or more commonly referred to as a metastasis. Primary ovarian lesions are rare manifestations corresponding to 0.5% of non-Hodgkin lymphoma and 1.5% of ovarian tumors. Clinic case: 31 years old female with general weakness, march incapacity, dyspnea, hyporexia, fever, diaphoresis, weight loss of 20 kg, flat abs with abdominal pain; Ca125 610 U/ml. Abdominal computed tomography shows a solid aspect tumor which affects the right pelvic cavity. Bilateral ovarian tumors were removed. Microscopically, both lesions show a "starry sky" pattern composed by a monotonous infiltration of lymphocytes mixed with large and clear macrophages, several atypical mitoses, and necrosis and hemorrhage areas. Immunohistochemistry was positive for CD10, CD20, and negative for CD3 and high Ki67 proliferation index. Bilateral ovarian Burkitt's lymphoma was diagnosed. Bilateral ovarian Burkitt's lymphoma is a rare entity, with a variability of presentations, the abdominal pain and abdominal tumors are the most frequent. The patient's prognosis at short term is poor, therefore it's necessary to know this entity and make an early diagnosis.

2015-01-01
There are very few reports in the literature of Castleman's disease affecting the carotid artery and a single previous report of a case of Castleman's disease of the neck originally mistaken as a carotid body tumor. We describe a rare case of Castleman's disease, manifesting with classic radiographic hallmarks of a carotid body tumor. The postoperative pathologic examination identified the resected mass as Castleman's lymphadenopathy. The management of this particular case is discussed, and the findings are highlighted. We present a unique case of a tumor initially and incorrectly diagnosed as a carotid body tumor. However, after comprehensive treatment with endovascular and surgical modalities and subsequent pathologic examination, the diagnosis of this rare entity was made.

Fibrolamellar carcinoma (FLC) has been considered a distinct clinical entity vs. hepatocellular carcinoma, with respect to its epidemiology, etiology, and prognosis. We describe the unusual case of a 23-year-old female patient with FLC and ovarian (Krukenberg) and peritoneal metastases, clinically mimicking an ovarian carcinoma. Multiple recurrences occurred despite initial R0 resection and chemotherapy, requiring surgical treatment. The patient survived five years and died from generalized disease. The particularities of our case are discussed by comparison with the other two similar cases and other date from the literature. To our knowledge, the ovarian involvement encountered in our case is the third case published in literature, being explained by the superficial location of the liver tumor.
Organizing Asian Pacific Islanders in an urban community to reduce HIV risk: a case study.
Loue, S; Lloyd, L S; Phoombour, E
1996-10-01
We present a case study of community organization efforts within the Asian Pacific Islander communities of San Diego County to reduce the risk of HIV transmission. We utilized a five-phase process to implement the strategies of locality development, social planning, and social action: community analysis, program design and initiation, program implementation, program maintenance and consolidation, and program reassessment. An evaluation of the process indicates that there were increases over time in the project's activities as well as in the levels of interagency connectedness. This is one of the few reported efforts to organize Asian Pacific Islander groups to address HIV transmission. Key elements that led to the successful organization of the original project into a tax-exempt nonprofit entity (the Asian Pacific Islander Community AIDS Project) were emphasis on community ownership, reliance on group consensus, use of "gatekeepers" to access communities, simultaneous multilevel programming, and service to the community as a "coordinating" entity.
Anomalous pulmonary venous connection: An underestimated entity.
Magalhães, Sara P; Moreno, Nuno; Loureiro, Marília; França, Manuela; Reis, Fernanda; Alvares, Sílvia; Ribeiro, Manuel
2016-12-01
Anomalous pulmonary venous connection is an uncommon congenital anomaly in which all (total form) or some (partial form) pulmonary veins drain into a systemic vein or into the right atrium rather than into the left atrium. The authors present one case of total anomalous pulmonary venous connection and two cases of partial anomalous pulmonary venous connection, one of supracardiac drainage into the brachiocephalic vein, and the other of infracardiac anomalous venous drainage (scimitar syndrome). Through the presentation of these cases, this article aims to review the main pulmonary venous developmental defects, highlighting the role of imaging techniques in the assessment of these anomalies.

Glandular and pseudoglandular tumors of the penile skin are extremely uncommon and can present diagnostic challenges. Primary adenosquamous carcinoma of the penis is an extremely rare tumor, composed of distinct areas of malignant squamous and glandular cells, making it a diagnostically challenging entity. The World Health Organization (WHO) recognizes several subtypes of squamous cell carcinoma (SCC), each with its own distinctive pathologic appearance, clinical associations and prognosis. Among these variants is the exceedingly uncommon adenosquamous carcinoma (ASC), representing 1%-2% of all SCC of the penis. Recent large studies have interrogated the presence of human papillomavirus (HPV) in malignant penile tumors and have shown specific morphologic patterns and clinical presentations to associate with HPV status. However, given the rarity of the adenosquamous variant of SCC, it has largely been excluded from these studies. The glandular components of these lesions can present a confusing appearance, particularly when a large tumor is represented on a small biopsy. Here we describe a difficult histologic presentation of this rare tumor, with the first published characterization of the HPV status of this subtype. This case represents a distinctly unusual case of metastatic HPV-positive primary cutaneous adenosquamous carcinoma of the penis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The authors report a rare case of multiple intraosseous inflammatory myofibroblastic tumors presenting with an aggressive clinical course. A 60-year-old man presented with a 3-month history of headache and 2 weeks of jaw pain. Magnetic resonance imaging showed a homogeneously enhancing mass in the right parietal bone with subcutaneous and intracranial invasion. Bone scintigraphy revealed 4 intraosseous lesions involving the cranium, mandible, ischium, and calcaneum. After admission, the patient showed left hemiparesis and seizures caused by rapid intracranial tumor extension. The cranial and mandible tumors were resected. Histopathological examinations of both specimens revealed myofibroblastic spindle cell proliferation with inflammatory cell infiltration, and a diagnosis of inflammatory myofibroblastic tumor was made. Two days postoperatively, the patient presented with a high fever and disturbance of consciousness with swelling of the subcutaneous tissues of the head and mandibular lesions. Magnetic resonance imaging revealed a massive intracranial extension of the tumor. Corticosteroid therapy induced remarkable shrinkage of all lesions, and relief from symptoms was obtained. Radiotherapy was then performed for residual tumors. Multiple intraosseous inflammatory myofibroblastic tumors of the bone are very uncommon and may mimic malignant tumors. It is important to recognize that this entity can occur in the cranium and as multiple bony lesions. The recommended treatment is complete surgical resection with adjuvant steroid treatment. Considering the aggressive nature of this entity, additional chemo- and/or radiotherapy may be warranted.
Nasopharyngeal branchial cysts-diagnosis and management: a case series.
Flis, Daniel W; Wein, Richard O
2013-02-01
Nasopharyngeal branchial cysts (NBCs) have been discussed in the literature in only a limited number of publications. Differing from Tornwaldt cysts, NBCs present laterally and arise from the fossa of Rosenmuller and may track superiorly within the bony confines of the Eustachian tube. Initially patients are asymptomatic but may present with aural fullness, unilateral conductive hearing loss, and serous otitis media as the cyst mass grows. Two of our three patients had the lesion incidentally identified at the time of assessment for another diagnosis. In this case series, imaging characteristics and response to treatment are reviewed. A literature search was performed to summarize the management options for this entity.

Myelolipoma in the mediastinum is an extremely rare entity. In this report, we present the case of a 79-year-old asymptomatic man who had three bilateral paravertebral mediastinal tumors. The three tumors were resected simultaneously using bilateral three-port video-assisted thoracoscopic surgery (VATS). There has been no evidence of recurrence within four years after the operation. Multiple bilateral mediastinal myelolipomas are extremely rare. There are no reports in the English literature of multiple bilateral thoracic myelolipomas that were resected simultaneously using bilateral VATS. We also present characteristic features of myelolipomas, which are helpful for diagnosis. PMID:24782978

Intracranial metastasis from breast cancer is a relatively common finding, however, the appearance of breast cancer metastasis in a meningioma is very rare. Several cases of tumor-to-tumor metastasis and collision tumors have been reported previously, with meningioma being implicated as the most common benign intracranial neoplasm to harbour the metastasis. Occasionally, the discovery of a tumor-to-meningioma metastasis may herald the diagnosis of an occult primary malignancy. Careful histopathological assessment of the resected meningioma specimen is pivotal to the management of these patients, as this will alter the treatment plan and prognosis considerably. Intracranial meningioma with collision breast cancer as primary presentation of an undiagnosed metastatic breast cancer is extremely rare. The current study presents a case of intracranial meningioma with collision breast cancer as a primary presentation, and reviews the available evidence for this unusual disease entity. PMID:29725531

breast metaplastic carcinomas are a heterogeneous group of neoplasms that exhibit a poor prognosis compared with invasive ductal carcinoma. Correspond less than 1% of all malignant neoplasms of the mammary gland. They usually present as high-grade tumors with a lower rate of lymph node metastases and decreased expression of estrogen and progesterone receptors and Her2 and increased expression of Her1 and Ki-67. we report a 52 year old woman with a breast carcinosarcoma presented with a left breast tumor fungated, ulcerated, polypoid and 18 cm in major diameter with lymph node metastases at diagnosis. She received multimodal management with neoadjuvant chemotherapy, followed by mastectomy and adjuvant chemotherapy; she presented progression of the disease with lung metastases and local massive recurrence, eventually died from complications associated to the disease. metaplastic carcinomas of the breast are extremely rare entities. Due the nature of disease and presentation, the prognosis is poor in these patients. There are several histologic subtypes based on studies of hematoxylin and eosin and immunohistochemical stains. It requires multimodal therapy (surgery, radiotherapy and chemotherapy) for best results.
Embedded object concept: case balancing two-wheeled robot
NASA Astrophysics Data System (ADS)
Vallius, Tero; Röning, Juha
2007-09-01
This paper presents the Embedded Object Concept (EOC) and a telepresence robot system which is a test case for the EOC. The EOC utilizes common object-oriented methods used in software by applying them to combined Lego-like software-hardware entities. These entities represent objects in object-oriented design methods, and they are the building blocks of embedded systems. The goal of the EOC is to make the designing of embedded systems faster and easier. This concept enables people without comprehensive knowledge in electronics design to create new embedded systems, and for experts it shortens the design time of new embedded systems. We present the current status of a telepresence robot created with Atomi-objects, which is the name for our implementation of the embedded objects. The telepresence robot is a relatively complex test case for the EOC. The robot has been constructed using incremental device development, which is made possible by the architecture of the EOC. The robot contains video and audio exchange capability and a controlling system for driving with two wheels. The robot consists of Atomi-objects, demonstrating the suitability of the EOC for prototyping and easy modifications, and proving the capabilities of the EOC by realizing a function that normally requires a computer. The computer counterpart is a regular PC with audio and video capabilities running with a robot control application. The robot is functional and successfully tested.
Round cell sarcomas beyond Ewing: emerging entities.
Antonescu, Cristina
2014-01-01
Primitive small blue round cell tumours (SBRCT) of childhood and young adults have been problematic to diagnose and classify. Diagnosis is also complicated in cases with atypical morphology, aberrant immunoprofiles and unusual clinical presentations. Even with the increased use of ancillary techniques in archival material, such as immunohistochemistry and molecular/genetic methods, a proportion of these tumours cannot be subclassified into specific histological types. A subset of tumours resembling microscopically the Ewing sarcoma family of tumours (EFT), being composed of primitive small round cells and occurring in paediatric or young adult age groups, remain unclassified, being negative for EWSR1, SS18(SYT), DDIT3(CHOP) and FOXO1(FKHR) gene rearrangements by FISH/RT-PCR. A small number of cases sharing the undifferentiated EFT appearance have been characterized recently carrying BCOR-CCNB3 or CIC-DUX4 fusions. However, based on the somewhat limited number of cases, it remains unclear if these newly defined genetic entities belong to any of the pre-existing clinicopathological disorders or represent altogether novel conditions. This review presents the latest molecular findings related to these SBRCTs, beyond the common EWSR1-ETS fusions. Specific attention has been paid to morphological features not associated typically with classic EFT, and the value of ancillary tests that can be applied when dealing with EWSR1-negative SBRCTs is discussed. © 2013 John Wiley & Sons Ltd.

Familial adenomatous polyposis (FAP) is an autosomal dominantly inherited intestinal polyposis syndrome with an incidence of about 1/8300 births and accounts for about 1% of all colorectal cancers. It has a spectrum of extra-intestinal manifestations including thyroid carcinoma which occur in 1-2% of affected. The cribriform morular variant (CMV) is a rare but distinct histological subtype of papillary thyroid carcinoma (PTC) associated with FAP. Most of the reported cases describe the above entity in the background of well-established FAP. We report a case where both entities presenting simultaneously in a previously undiagnosed patient with FAP without a family history of polyposis. A 24 year old Asian female presented to the surgical clinic with a goitre of eight months duration and recent onset of altered bowel habits with features of anaemia. She was previously healthy and there was no family history of adenomatous polyposis, colorectal carcinoma or thyroid neoplasms. Colonoscopy revealed large bowel polyposis and fine needle aspiration of thyroid revealed a smear suspicious for malignancy. She underwent total thyroidectomy which revealed CMV PTC. Histology was characterized by a prominent cribriform pattern of growth with interspersed cell clusters arranged as morules along with papillary structures which are the key features of this subtype. Diagnosis of CMV warrants ruling out of underlying FAP, irrespective of family history or gastrointestinal symptoms.
Pseudoangiomatous stromal hyperplasia causing massive breast enlargement
Bourke, Anita Geraldine; Tiang, Stephen; Harvey, Nathan; McClure, Robert
2015-01-01
Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign mesenchymal proliferative process, initially described by Vuitch et al. We report an unusual case of a 46-year-old woman who presented with a 6-week history of bilateral massive, asymmetrical, painful enlargement of her breasts, without a history of trauma. On clinical examination, both breasts were markedly enlarged and oedematous, but there were no discrete palpable masses. Preoperative image-guided core biopsies and surgery showed PASH. PASH is increasingly recognised as an incidental finding on image-guided core biopsy performed for screen detected lesions. There are a few reported cases of PASH presenting as rapid breast enlargement. In our case, the patient presented with painful, asymmetrical, massive breast enlargement. Awareness needs to be raised of this entity as a differential diagnosis in massive, painful breast enlargement. PMID:26475873

Extranodal natural killer/T-cell lymphoma (NKTL), nasal-type is one of the most aggressive lymphoid malignancies and is characterized by an extremely poor survival outcome. The present study reports the case of a 39-year-old Chinese male with history of extranodal NKTL who presented with a painless indurated mass in the glans penis. The results of an incisional biopsy revealed atypical cells that were positive for CD3, CD56, T-cell-restricted intracellular antigen-1, granzyme B and Epstein-Barr virus-encoded RNA, and negative for CD20. A diagnosis of metastatic NKTL was determined. The patient was treated with systemic chemotherapy consisting of cisplatin, dexamethasone, gemcitabine and pegaspargase, which resulted in remission and regression of the mass. In addition, a review of the literature was performed, and the data for 13 cases of non-B-cell penile lymphoma, including the present case, are presented. To the best of our knowledge, this is first review of this entity.

Chronic lingual papulosis: new, independent entity or "mature" form of transient lingual papillitis?
Bouquot, Jerry E; Adibi, Shawn S; Sanchez, Maga
2012-01-01
Several acute, usually pediatric variants of edematous, symptomatic fungiform lingual papillitis have been reported since the 1990s, most notably transient lingual papillitis (TLP); but no chronic forms have been mentioned. Is there a chronic counterpart, akin to the older palatal examples of inflammatory papillary hyperplasia? The objective of this study was to clinicopathologically characterize a previously unreported entity with clustered, chronic fibrous papules (nonsyndromic) of the tongue. Cases were collected from clinics in 2 dental schools. Five women and 4 men were identified with multiple, moderately firm, slightly pedunculated, normally colored masses clustered at the tip of the tongue (n = 4), covering the dorsal surface (n = 4) or on the lateral border (n = 1); 2 showed several erythematous or edematous papules (similar to TLP) admixed with fibrous papules. Patient ages ranged from 31 to 62 years (average 49) and all lesions had been present for many years. All lesions were asymptomatic except for the lateral border lesion, which presented with a burning sensation and mild tenderness (disappeared with antifungal medication). Five cases were associated with mouth breathing or a tongue-thrust habit; 4 were associated with geographic tongue or fissured tongue. Four papules were biopsied. All were composed of dense, avascular fibrous tissue with no or very few inflammatory cells; one showed focal mild neovascularity and edema. The lesion appeared to represent altered filiform papillae, more so than fungiform papillae. Chronic lingual papulosis (CLP) is an innocuous entity represented by focal or diffuse enlargement of numerous lingual papillae, primarily the filiform papillae. It appears to usually have an adult onset and most likely represents papillary reaction to very low-grade, chronic irritation or desiccation. Some cases with childhood onset, however, seem to be variations of normal anatomy. No treatment or biopsy is required, but a number of systemic disorders and syndromes must be ruled out before applying the CLP diagnosis. Copyright © 2012 Elsevier Inc. All rights reserved.
Swyer Syndrome With Gonadoblastoma: A Clinicoradiological Approach.
Agarwal, Arjit; Agarwal, Shubhra
2017-01-01
Primary amenorrhea is a common diagnostic challenge in the gynecology department, wherein there are numerous causes that need to be approached in a systematic manner. However, when a case with a pelvic lump or a solid pelvic mass presents to a gynecologist or a radiologist, the approach becomes difficult to justify amenorrhea and pelvic mass as a single entity. We present the case of a 36-year-old female with the complaints of primary amenorrhea with a pelvic mass. The case was approached keeping in view the diagnostic possibilities and applying the role of clinical, radiological, and laboratory analyses. The final diagnosis of Swyer syndrome with gonadoblastoma was made, and she was further subjected to operative resection and hormonal therapy. This study stresses on the approach to a case, wherein the diagnosis was based only on the clinician's acumen and the radiologist's expertise, providing a way to simplify the protocol in the evaluation of such types of cases.

Inverted follicular keratosis (IFK) is a rare benign tumor which usually appears as a firm papule on the face. The diagnosis is generally made by histopathology because the clinical appearance is difficult to differentiate from other lesions. Dermoscopic features of IFK have not been established to date. Herein we describe the dermoscopic findings of 4 cases of IFK. Radial peripheral hairpin vessels surrounded by a whitish halo arranged around a central white-yellowish amorphous area were observed in 3 cases, and glomerular vessels were present in the central area of one of them. The fourth case also presented a central white amorphous area but showed arborizing vessels. Reflectance confocal microscopy (available in 1 case) revealed a broadened honeycomb pattern, epidermal projections and hairpin and glomerular vessels. To our knowledge this is the first case series describing the dermoscopic features of inverted follicular keratosis and the first confocal microscopy description of this entity.
Acute Infantile Encephalopathy Predominantly Affecting The Frontal Lobes (AIEF).
Raha, Sarbani; Udani, Vrajesh
2012-12-01
Acute Infantile Encephalopathy Predominantly Affecting the Frontal Lobes (AIEF) is a relatively recent described entity. This article includes case reports of two patients who had bifrontal involvement during acute febrile encephalopathy. Case 1 describes a 1-y-old boy who presented with hyperpyrexia and dialeptic seizures. Imaging revealed significant bilateral frontal lobe involvement while serology proved presence of Influenza B infection. Over a period of one wk, he recovered with significant cognitive decline and perseveratory behavior. Another 6-y-old boy presented with language and behavioral problems suggestive of frontal dysfunction after recovering from prolonged impairment of consciousness following a convulsive status epilepticus. Bilateral superior frontal lesions with gyral swelling was evident on neuroimaging. These cases are among the very few cases of AIEF described in recent literature and the article also reviews this unique subtype of acute encephalopathy.
Epithelioid inflammatory myofibroblastic sarcoma: a case report
Clevenger, Jessica A.; Masters, Gregory A.; Bauer, Thomas L.; Nam, Brian T.
2015-01-01
Inflammatory myofibroblastic tumor (IMT) of the lung is a rare malignancy with few cases reported in the literature. Histologically, it is composed by spindle cells and an infiltrate of inflammatory cells. Children and young, non-smoking adults constitute the majority of cases, the clinical behavior ranges from a benign entity to a malignant process with rapid recurrence and metastatic progression. We present a case of epithelioid inflammatory myofibroblastic sarcoma (EIMS) of the pleura, a malignant variant of IMT, which was initially treated with debulking surgical resection followed by systemic chemotherapy. The tumor was found to have an anaplastic lymphoma kinase (ALK) gene rearrangement. An ALK directed tyrosine kinase inhibitor was used with an impressive response, the patient remains in remission nearly 1 year after presentation. The pathogenesis, pathologic findings, clinical behavior and imaging of pulmonary EIMS are discussed. PMID:26623133

The finding of gas within the gastric wall is not a disease by itself, rather than a sign of an underlying condition which could be systemic or gastric. We present the case of a woman identified with gastric emphysema secondary to the administration of high doses of steroids, with the purpose of differentiating emphysematous gastritis versus gastric emphysema due to the divergent prognostic implications. Gastric emphysema entails a more benign course, opposed to emphysematous gastritis which often presents as an acute abdomen and carries a worse prognosis. Owing to the lack of established diagnostic criteria, computed tomography is the assessment method of choice. Currently no guidelines are available for the management of this entity, since the evidence is limited to a few case series and a considerable number of single case reports. PMID:25093129

Brown tumors are erosive bony lesions caused by rapid osteoclastic activity and peritrabecular fibrosis due to hyperparathyroidism, resulting in a local destructive phenomenon. The classical “brown tumor” is commonly seen in ends of long bones, the pelvis and ribs. Facial involvement is rare and, when present, usually involves the mandible. We report a case of 60-year-old male with a rare initial presentation of primary hyperparathyroidism with bilateral maxillary brown tumors. The present case represents the third report of the bilateral maxillary brown tumors in a patient with primary hyperparathyroidism. Differential diagnosis is important for the right treatment choice. It should exclude other giant cell lesions that affect the maxillae. PMID:21731279

Osteoblastoma is a benign bone tumour found commonly in the spine and long tubular bones. Involvement of the talus is uncommon, and when present, is found in the neck of the talus. Osteoblastoma of the body of talus is a very rare entity. We report a young male, presenting as chronic ankle pain, with a radiolucent lesion with a thick periosteal shell in the body of the talus. Analysis of clinical, radiological and histological findings confirmed the diagnosis of osteoblastoma. The case is reported for the rarity of the site and atypical radiological features that osteoblastoma can present with. Copyright 2009 European Foot and Ankle Society. Published by Elsevier Ltd.

Primary aortic neoplasms are rare. Aortic sarcoma arising after endovascular aneurysm repair (EVAR) is a scarce subset of primary aortic malignancies, reports of which are infrequent in the published literature. The diagnosis of aortic sarcoma is challenging due to its non-specific clinical presentation, and the prognosis is poor due to delayed diagnosis, rapid proliferation, and propensity for metastasis. Post-EVAR, aortic sarcomas may mimic other more common aortic processes on surveillance imaging. Radiologists are rarely knowledgeable about this rare entity for which multimodality imaging and awareness are invaluable in early diagnosis. A series of three pathologically confirmed cases are presented to display the multimodality imaging features and clinical presentations of aortic sarcoma arising after EVAR.

Hemobilia secondary to gallbladder polyposis is rare in children but has been reported in a few children with metachromatic leukodystrophy. We present a case with preoperative multidetector computed tomography (MDCT) diagnosis of massive hemobilia caused by gallbladder polyposis in a patient with metachromatic leukodystrophy. Our report highlights the importance of both awareness of the association of gallbladder polyposis with other syndromes such as metachromatic leukodystrophy as well as the possibility of this entity presenting with life-threatening bleeding.

Sclerosing pseudotumour of the orbit is a rare idiopathic chronic inflammatory process, which greatly mimics neoplasms both clinically and on imaging studies. It is therefore important to differentiate this entity from true neoplasms and to rule out any systemic associations. We present a rare case of sclerosing orbital pseudotumour in an adult man with no systemic illnesses who presented with painless progressive proptosis of both eyes and showed a gradual initial response to steroid therapy but relapsed after a 2-year interval.

Peripheral primitive neuroectodermal tumors (PNET) are rare malignant tumors, affecting mostly children and adolescents and have been described in breast in eight case reports only. In this paper, we present a case of bilateral mammary ES/PNET where distinction between primary and metastatic diseases was discussed through a literature review. The aim of this work is to demonstrate that although rare, the possibility of PNET should be kept in mind while evaluating a palpable breast abnormality in a young female. PMID:23819085
Breast hematoma complicating anticoagulant therapy: management and literature review.
Salemis, Nikolaos S
2012-01-01
Anticoagulant-induced spontaneous breast hematoma is a very rare clinical entity with only a few cases reported in the literature so far. We describe a case of a spontaneous breast hematoma in a female patient under combined oral anticoagulant and antiplatelet therapy. Physicians should be aware of this possibility in patients under anticoagulant treatment presenting with sudden onset of breast pain and a palpable mass. Repeat imaging is mandatory until complete clinical and imaging resolution of the hematoma. If an abnormality persists, further investigation is needed to exclude an underlying malignancy.
A Rare Case of Ileocecal Tuberculosis with Pulmonary Embolism and Deep Vein Thrombosis

Venous thromboembolism in tuberculosis is not a well recognised entity. It is a less frequently reported complication of severe pulmonary tuberculosis. It is exceedingly rare when it complicates extrapulmonary tuberculosis. Here, we present a case of 22-year-old young female with abdominal tuberculosis complicated with reverse ileocecal intussusception, deep vein thrombosis and pulmonary embolism. An emergency vena cava filter was inserted prior to a limited right hemicolectomy. In this article, we discuss the rare association of venous thromboembolism with ileocecal tuberculosis.

Hyperparathyroidism can present itself as brown tumors (or osteolytic expansive lesions) that usually disappear after normalization of calcium and phosphate levels. It rarely occurs simultaneously with a giant cell tumor. The authors report one case of a localized form at the distal radius in a patient being followed for primary hyperparathyroidism. The diagnostic challenges related to the clinical and radiological similarities of these two pathological entities are discussed, as they can lead to delays in therapeutic management.

Exacerbation of pre-existing diabetes insipidus during pregnancy, mechanisms and management.
Tack, Lloyd J W; T'Sjoen, Guy; Lapauw, Bruno
2017-06-01
During pregnancy, physiological changes in osmotic homeostasis cause water retention. If excessive, this can cause gestational diabetes insipidus (DI), particularly in patients with already impaired vasopressin secretion. We present the case of a 34-year-old patient with pre-existing hypopituitarism who experienced a transient exacerbation of her DI during a twin pregnancy. In contrast to typical gestational DI, polyuria and polydipsia occurred during the first trimester and remained stable thereafter. This case highlights a challenging clinical entity of which pathophysiology, diagnostic approach and treatment will be discussed.
Etiology and management of spontaneous haemothorax

Spontaneous haemothorax (SH) is a subcategory of haemothorax that involves the accumulation of blood within the pleural space in the abscence of trauma or other causes. The clinical presentation is variable and includes a rapid progression of symptoms of chest pain and dyspnea that can be life threatening when hemodynamic instability and hypovolemic shock occurs. Despite haemothorax, SH is much less common with data limited to case reports and case series. A literature review has been performed to identify and summarise all potentials causes leading to this clinical entity. PMID:25922734

While pneumatosis cystoides intestinalis (PCI) is a rare disease entity associated with a wide variety of gastrointestinal and non-gastrointestinal disorders, PCI associated with massive intra- and retroperitoneal free air is extremely uncommon, and is difficult to diagnose differentially from perforated peritonitis. We present two cases of PCI associated with massive peritoneal free air and/or retroperitoneal air that mimicked perforated peritonitis. These cases highlight the clinical importance of PCI that mimics perforated peritonitis, which requires emergency surgery. Preoperative imaging modalities and diagnostic laparoscopy are useful to make an accurate diagnosis.

Signet-ring cell cancers deriving from the bladder are rare entities and usually present with advanced incurable disease and associated poor outlook. No standard effective chemotherapeutic option has been described largely due to the rarity of this malignancy. We report a case of a patient with metastatic bladder cancer, signet-ring cell variant. The patient progressed rapidly on standard first-line bladder cancer chemotherapy with gemcitabine and carboplatin. He responded well to second-line capecitabine with a clinically meaningful progression-free survival. PMID:20368884

Soft tissue infection due to Mycobacterium tuberculosis can affect muscle, tendons, fascia, bursa and synovial tissue. Tuberculous trochanteric bursitis is a rare entity that usually affects immunocompromised patients. Manifestations usually occur insidiously, which delays diagnosis and treatment. We present the case of an immunocompetent young woman who came to our department for chronic left hip pain. The study confirms the diagnosis of tuberculous trochanteric bursitis. This case demonstrates the importance of considering a possible infectious origin of bursitis in immunocompetent patients. Copyright © 2010 Elsevier España, S.L. All rights reserved.

Reference has been made in the literature of the variability in the clinical presentation of deficiency of complex III of the respiratory chain, identifying up to the moment, four groups, the first of which is characterized by hipotonia and wearness starting at variable ages. We report a new case of mitochondrial myopathy due to deficiency of this complex and included within this first group, and consider the importance of defining the clinical and histochemical characteristics of this polymorphous entity.

Introduction Nonparasitic splenic cysts are uncommon clinical entity and because of it, there is no information regarding their optimal surgical treatment. Case presentation A 41-years-old female with incidentally diagnosed nonparasitic splenic cyst which initially was asymptomatic. After two years of follow up, the patient underwent surgery; subtotal cystectomy and omentoplasty as an additional procedure. Postoperative course was uneventful. Conclusion Short and mid term results showed that near total cystectomy with omentoplasty was a safe successful procedure for treatment of epidermoid splenic cyst. PMID:19829799

Pneumothorax is a common complication following blunt chest wall trauma. In these patients, because of the restrictions regarding immobilization of the cervical spine, Anteroposterior (AP) chest radiograph is usually the most feasible initial study which is not as sensitive as the erect chest X-ray or CT chest for detection of a pneumothorax. We will present 3 case reports which serve for better understanding of the entity of occult pneumothorax. The first case is an example of a true occult pneumothorax where an initial AP chest X-ray revealed no evidence of pneumothorax and a CT chest immediately performed revealed evidence of pneumothorax. The second case represents an example of a missed rather than a truly occult pneumothorax where the initial chest radiograph revealed clues suggesting the presence of pneumothorax which were missed by the reading radiologist. The third case emphasizes the fact that "occult pneumothorax is predictable". The presence of subcutaneous emphesema and pulmonary contusion should call for further imaging with CT chest to rule out pneumothorax. Thoracic CT scan is therefore the "gold standard" for early detection of a pneumothorax in trauma patients. This report aims to sensitize readers to the entity of occult pneumothorax and create awareness among intensivists and ER physicians regarding the proper diagnosis and management.
Granular cell tumour of the neurohypophysis: an unusual cause of hypopituitarism.
Bello, Carlos Tavares; Cipriano, Patricia; Henriques, Vanessa; Duarte, João Sequeira; Marques, Conceição Canas
2018-01-01
Granular cell tumours (GCT) are rare, slow-growing, benign neoplasms that are usually located in the head and neck. They are more frequent in the female gender and typically have an asymptomatic clinical course, being diagnosed only at autopsy. Symptomatic GCT of the neurohypophysis are exceedingly rare, being less than 70 cases described so far. The authors report on a case of a 28-year-old male that presented to the Endocrinology clinic with clinical and biochemical evidence of hypogonadism. He also reported minor headaches without any major visual symptoms. Further laboratory tests confirmed hypopituitarism (hypogonadotrophic hypogonadism, central hypothyroidism and hypocortisolism) and central nervous system imaging revealed a pituitary macroadenoma. The patient underwent transcranial pituitary adenoma resection and the pathology report described a GCT of the neurohypophysis with low mitotic index. The reported case is noteworthy for the rarity of the clinicopathological entity. Symptomatic GCTs are rare CNS tumours whose cell of origin is not well defined that usually give rise to visual symptoms, headache and endocrine dysfunction.Imaging is quite unspecific and diagnosis is difficult to establish preoperatively.Surgical excision is challenging due to lesion's high vascularity and propensity to adhere to adjacent structures.The reported case is noteworthy for the rarity of the clinicopathological entity.

An Information Model is comprised of graphical and textual notation suitable for describing and defining the problem domain - in our case, TUNS or TCIS. The model focuses on the real world under study. It identifies what is in the problem and organizes the data into a formal structure for documentation and communication purposes. The Information Model is composed of an Entity Relationship Diagram (ERD) and a Data Dictionary component. The combination of these components provide an easy to understand methodology for expressing the entities in the problem space, the relationships between entities and the characteristics (attributes) of the entities. This approach is the first step in information system development. The Information Model identifies the complete set of data elements processed by TUNS. This representation provides a conceptual view of TUNS from the perspective of entities, data, and relationships. The Information Model reflects the business practices and real-world entities that users must deal with.

2008-01-01
Seborrheic keratosis of the penis is a rare entity. It has been mistaken as genital warts and differentiation is only made on histopathology. We are reporting a case presenting as multiple giant polypoidal lesions on the penile skin for the last 20 years. Seborrheic keratosis should be considered in the differential diagnosis of pedunculated lesions of the penis. The histopathology after shave excision will be diagnostic. PMID:19967020
Pneumonitis in Adult Onset Still's Disease: Uncommon or Under Diagnosed?
Fernandes, Silvia; Almeida, Margarida; Pereira da Silva, José Alberto; Romeu, José Carlos
2017-08-31
The adult onset Still's Disease is an uncommon entity characterized by multiple clinical manifestations. Pneumonitis, less often considered, deserves particular emphasis given the need for differential diagnosis and because it can progress to severe respiratory failure. With the aim to highlight the pulmonary parenchyma involvement in patients with adult onset Still's Disease, we present a case report which progresses with pneumonitis.
Collagenous gastritis: an unusual association with profound weight loss.
Wang, Hanlin L; Shah, Amit G; Yerian, Lisa M; Cohen, Russell D; Hart, John
2004-02-01
Collagenous gastritis is a distinctive disorder characterized by thickening of the subepithelial collagen layer in the gastric mucosa. Although this entity was recognized in 1989, its etiology, pathogenesis, and clinicopathologic features remain poorly understood because of its rarity. An unusual case of collagenous gastritis was observed in a 37-year-old man who presented with profound weight loss, a feature that has not previously been emphasized.
HIPAA Business Associate Contracts: the value of contracts for case managers.
Muller, Lynn S
2003-01-01
Case Managers are in the middle of the upcoming HIPAA regulation changes, with the issuance of the Final Privacy Rule. Every case obliges case managers to work with Individually Identifiable Health Information (IIHI) and Protected Health Information (PHI). The purpose of this article is to provide case managers in all practice settings with a clear understanding of a "Business Associate," of a "Covered Entity," and of the specifics of a Business Associate Contract. This information will demonstrate how case managers can benefit from the use of these contracts in their business life. As an essential component of an organization's compliance plan, Business Associate Contracts can become a sword or a shield. This article is particularly helpful to case managers in independent practice, as well as those who work for Covered Entities.

Urban metabolism is a basic theory for coping with global environmental problems, which is coherent with the aims of national environmental management. This paper analyzed the concept of urban metabolism, and pointed out the meaning for urban metabolism in physical space entities; reviewed the current methods for urban metabolism and its merits and shortages; analyzed the system boundaries, connotation, and methodologies; and summarized the advances on urban meta-bolism practices in physical space entities. At last, we made conclusions that there were shortages, including conception system, basic theory system, and interdisciplinary integrated theory system in current urban metabolism research, and the current cases studied in urban metabolism were limited and not suitable to the harmony development between society, economy, and environment. In the future, we need to strengthen comparison between different case studies from different countries, develop the prior modes of typical urban metabolism research, identify the mechanism for urban ecosystem, and strengthen the spatial decision support system of environmental management taking urban spatial entity spaces as units.

Anti-glutamic acid decarboxylase (anti-GAD65) antibodies are a rare cause of autoimmune encephalitis. This entity is mainly recognized in adults and very few cases were reported in children. We report on a paediatric case of anti-GAD encephalitis with severe presentation and uncontrollable dysautonomia. A 9-year-old girl was referred to our department for refractory seizures and behavioral disturbances. Brain magnetic resonance imaging (MRI) was normal. Repeat screening for antineuronal antibodies showed negative results for anti-NMDA receptor antibodies but positive results for anti-GAD65 with a low positivity of anti-Ma2 antibodies. Although a transient improvement was noticed after immunomodulatory treatment, the patient developed severe intractable autonomic imbalance including dysrythmia, alternating bradycardia/tachycardia, hypotension/hypertension, hypothermia/hyperthermia and hyperhidrosis. She deceased six months after onset. Our report intends to raise awareness of autoimmune encephalitis with anti-GAD65 antibodies which may involve extralimbic brain regions and manifest with fatal dysautonomia. We highlight the need for prompt diagnosis and aggressive management for this underdiagnosed entity in children. Copyright © 2018 European Paediatric Neurology Society. Published by Elsevier Ltd.

Elemental impurities in drug products can arise from a number of different sources and via a number of different means, including the active pharmaceutical ingredient, excipients, the vehicle, and leaching of elemental entities that are present in the drug product's manufacturing or packaging systems. Thus, knowledge about the presence, level, and likelihood of leaching of elemental entities in manufacturing and packaging systems is relevant to understanding how these systems contribute to a drug product's total elemental impurity burden. To that end, a joint team from the Extractables and Leachables Safety Information Exchange (ELSIE) Consortium and the International Pharmaceutical Aerosol Consortium on Regulation and Science (IPAC-RS) has conducted a review of the available literature on elemental entities in pharmaceutically relevant polymers and the presence of these elemental entities in material extracts and/or drug products. This review article contains the information compiled from the available body of literature and considers two questions: (1) What elemental entities are present in the relevant polymers and materials and at what levels are they present? (2) To what extent are these elemental entities leached from these materials under conditions relevant to the manufacturing and storage/distribution of solution drug products? Conclusions drawn from the compiled data are as follows: (1) Elemental entities are present in the materials used to construct packaging and manufacturing systems as these materials either contain these elemental entities as additives or are exposed to elemental entities during their production. (2) Unless the elemental entities are parts of the materials themselves (for example, SiO 2 in glass) or intentionally added to the materials (for example, metal stearates in polymers), their incidental amounts in the materials are generally low. (3) When elemental entities are present in materials and systems, generally only a very small fraction of the total available amount of the entity can be leached under conditions that are relevant to packaged drug products. Thus, while sources of certain elemental impurities may be ubiquitous in the natural environment, they are not ubiquitous in materials used in pharmaceutical packaging and manufacturing systems and when they are present, they are not extensively leached under relevant conditions. The information summarized here can be utilized to aid the elemental impurity risk assessment process by providing the identities of commonly reported elements and data to support probability estimates of those becoming elemental impurities in the drug product. Furthermore, recommendations are made related to establishing elements of potential product impact for individual materials. Extraneous impurities in drug products provide no therapeutic benefit and thus should be known and controlled. Elemental impurities can arise from a number of sources and by a number of means, including the leaching of elemental entities from drug product packaging and manufacturing systems. To understand the extent to which materials used in packaging systems contain elemental entities and the extent to which those entities leach into drug products to become elemental impurities, the Extractables and Leachables Safety Information Exchange (ELSIE) and International Pharmaceutical Aerosol Consortium on Regulation and Science (IPAC-RS) Consortia have jointly performed a literature review on this subject. Using the compiled information, it was concluded that while packaging materials may contain elemental entities, unless those entities are intentional parts of the materials, the amounts of those elemental entities are generally low. Furthermore, generally only a very small fraction of the total available amount of the entity can be leached under conditions that are relevant to packaged drug products. Thus, risk assessment of sources of elemental impurities in drug products that may be related to materials used in pharmaceutical packaging and manufacturing systems can utilize the information and recommendations presented here. © PDA, Inc. 2015.

Morel-Lavallée lesions are posttraumatic hemolymphatic collections caused by disruption of the interfascial planes between the subcutaneous soft tissue and muscle. Severe peripelvic Morel-Lavallée lesions have rarely been reported in the literature. By contrast, a number of cases of gluteal muscle necrosis following transcatheter angiographic embolization for pelvic fracture have been reported. Each entity can result in severe infection and sepsis, and the mortality rate in such cases is quite high. However, to date, no previous reports have described a case in which these life-threatening entities occurred simultaneously. A 32-year-old Asian man simultaneously developed severe peripelvic Morel-Lavallée lesions and gluteal muscle necrosis with sepsis following transcatheter angiographic embolization after an unstable pelvic fracture. Extremely large skin and soft tissue defects, which were untreatable with any commonly used flaps, were generated after repeated debridement. In addition, a deep-bone infection was suspected in his left fractured iliac bone, while motor function was almost completely lost in his left leg, possibly as a sequela of transcatheter angiographic embolization. As a result of his condition, a left hemipelvectomy was unavoidable. A pedicled fillet flap from his sacrificed left limb was used for the treatment of the defects and to provide a durable base for a prosthesis. Our patient survived and returned to his previous job 24 months after the surgery wearing a prosthetic left leg. As illustrated by the present case, severe peripelvic Morel-Lavallée lesions and gluteal muscle necrosis following transcatheter angiographic embolization can occur simultaneously after unstable pelvic fractures. Physicians should recognize that these entities can result in life-threatening sepsis and, therefore, should attempt to detect them as early as possible. When hemipelvectomy is unavoidable, a pedicled upper and lower leg in-continuity fillet flap may provide satisfactory outcomes.

We introduce a class of solitonlike entities in spinor three-component Bose-Einstein condensates. These entities generalize well-known solitons. For special values of coupling constants, the system considered is completely integrable and supports N soliton solutions. The one-soliton solutions can be generalized to systems with different values of coupling constants. However, they no longer interact elastically. When two so-generalized solitons collide, a spin component oscillation is observed in both emerging entities. We propose to call these newfound entities oscillatons. They propagate without dispersion and retain their character after collisions. We derive an exact mathematical model for oscillatons and show that the well-knownmore » one-soliton solutions are a particular case.« less
Endoscopic Endonasal Transsphenoidal Drainage of a Spontaneous Candida glabrata Pituitary Abscess.
Strickland, Ben A; Pham, Martin; Bakhsheshian, Joshua; Carmichael, John; Weiss, Martin; Zada, Gabriel
2018-01-01
Noniatrogenic pituitary abscess remains a rare clinical entity, and is the indication for surgery in <1% of transsphenoidal approaches. Correct diagnosis of this rare entity is often delayed. Without timely treatment, morbidity and mortality are high. Of the 200 cases reported to date, less than one-half have identified a causative organism. We report the second case of a pituitary abscess caused by Candida species, and also provide an intraoperative video showing the endoscopic management of this pathology. A 33-year-old woman presented with headache, hypopituitarism, and vision loss in the setting of diabetic ketoacidosis, and was found to have multiple abscesses in the liver, lung, kidney, and uterus. Brain magnetic resonance imaging revealed a 15-mm cystic sellar mass with restricted diffusion. The patient underwent urgent evacuation of the abscess via an endoscopic endonasal transsphenoidal route, with obvious purulent material filling the sella, later identified as Candida glabrata. Antimicrobial therapy was refined appropriately, and she exhibited significant improvement in neurologic function, although endocrinopathy has persisted. With timely management, including a combination of surgical drainage and appropriate antimicrobial therapy, neurologic outcomes are good in most cases of pituitary abscess; however, endocrinopathy often does not improve. Although most reported cases with identified causative organisms speciate bacteria, some cases are of fungal etiology and require different antimicrobial agents. This further underscores the importance of identifying the causative agent. Copyright © 2017 Elsevier Inc. All rights reserved.
[CLINICAL ENTITIES AND CHARACTERISTICS OF PAIN IN PATIENTS WITH RHEUMATIC DISEASES].
Prus, Višnja; Kardum, Željka
Musculoskeletal pain is the most common symptom present in almost all rheumatic diseases. Rheumatic diseases include more than 150 clinical entities. There is no uniform classification of rheumatic diseases. In general, we distinguish inflammatory rheumatic diseases, non-inflammatory degenerative articular diseases, systemic connective tissue diseases, metabolic disorders with articular manifestations, and regional and extended pain syndromes. According to the International Association for the Study of Pain (IASP), pain is defined as an unpleasant sensation associated with tissue damage or reported simultaneously with such damage. Pain has a physical, mental, and social component. In rheumatic diseases the pain is mostly chronic and may severely impair the patient’s general condition. The defining criteria involve a period of more than 3 or 6 months, and according to some definitions more than 6 weeks. In most cases the pain is nociceptive rather than neuropathic. Musculoskeletal pain, especially chronic pain, is a global public health problem because of its prevalence, as well as the frequently associated muslculoskeletal function impairment and development of chronic pain syndrome, which can be considered as a separate clinical entity and requires a biopsychosocial treatment approach.
A Cross-disciplinary Framework for the Description of Contextually Mediated Change
NASA Astrophysics Data System (ADS)
Gabora, Liane; Aerts, Diederik
We present a mathematical framework (referred to as Context-driven Actualization of Potential, or CAP) for describing how entities change over time under the influence of a context. The approach facilitates comparison of change of state of entities studied in different disciplines. Processes are seen to differ according to the degree of nondeterminism, and the degree to which they are sensitive to, internalize, and depend upon a particular context. Our analysis suggests that the dynamical evolution of a quantum entity described by the Schrödinger equation is not fundamentally different from change provoked by a measurement often referred to as collapse but a limiting case, with only one way to collapse. The biological transition to coded replication is seen as a means of preserving structure in the face of context, and sexual replication as a means of increasing potentiality thus enhancing diversity through interaction with context. The framework sheds light on concepts like selection and fitness, reveals how exceptional Darwinian evolution is as a means of 'change of state', and clarifies in what sense culture (and the creative process underlying it) are Darwinian.
Acquired bilateral telangiectatic macules: a distinct clinical entity.
Park, Ji-Hye; Lee, Dong Jun; Lee, Yoo-Jung; Jang, Yong Hyun; Kang, Hee Young; Kim, You Chan
2014-09-01
We evaluated 13 distinct patients with multiple telangiectatic pigmented macules confined mostly to the upper arms to determine if the clinical and histopathological features of these cases might represent a specific clinical entity. We retrospectively investigated the clinical, histopathologic, and immunohistochemical features of 13 patients with multiple telangiectatic pigmented macules on the upper arms who presented between January 2003 and December 2012. Epidermal pigmentation, melanogenic activity, melanocyte number, vascularity, epidermal thickness, and perivascular mast cell number of the specimens were evaluated. Clinically, the condition favored middle-aged men. On histopathologic examination, the lesional skin showed capillary proliferation and telangiectasia in the upper dermis. Histochemical and immunohistochemical analysis revealed basal hyperpigmentation and increased melanogenic activity in the lesional skin (P < .05). No significant difference in epidermal thickness or mast cell number was observed between the normal perilesional skin and the lesional skin. The clinical and histopathologic features of these lesions were relatively consistent in all patients. In addition, the features are quite distinct from other diseases. Based on clinical and histologic features, we suggest the name acquired bilateral telangiectatic macules for this new entity.
Dissecting disease entities out of the broad spectrum of bipolar-disorders.
Levine, Joseph; Toker, Lilach; Agam, Galila
2018-01-01
The etiopathology of bipolar disorders is yet unraveled and new avenues should be pursued. One such avenue may be based on the assumption that the bipolar broad spectrum includes, among others, an array of rare medical disease entities. Towards this aim we propose a dissecting approach based on a search for rare medical diseases with known etiopathology which also exhibit bipolar disorders symptomatology. We further suggest that the etiopathologic mechanisms underlying such rare medical diseases may also underlie a rare variant of bipolar disorder. Such an assumption may be further reinforced if both the rare medical disease and its bipolar clinical phenotype demonstrate a] a similar mode of inheritance (i.e, autosomal dominant); b] brain involvement; and c] data implicating that the etiopathological mechanisms underlying the rare diseases affect biological processes reported to be associated with bipolar disorders and their treatment. We exemplify our suggested approach by a rare case of autosomal dominant leucodystrophy, a disease entity exhibiting nuclear lamin B1 pathology also presenting bipolar symptomatology.

Solitary metastases after surgically-treated cervical cancer are a rare entity, with only few cases described so far. We present the case of a 31-year-old patient diagnosed with a tumoral splenic lesion at 18 months after surgically-treated cervical cancer. The patient was submitted to surgery, with a splenectomy being performed. The histopathological studies confirmed the presence of a squamous cell cervical cancer splenic metastasis. At one year follow-up after splenectomy, the patient is free of any recurrent disease. Solitary splenic metastases after surgically-treated cervical cancer are rarely seen; however, this diagnostic should not be omitted whenever a medical history of cervical cancer is present.

A Rare Case Report of Immobility-Induced Hypercalcemia in an Infant.
Vyas, Neha; Kaminski, Beth; MacLeish, Sarah
2016-04-01
Immobility-induced hypercalcemia is a rare cause of hypercalcemia in children, and to our knowledge it has never been reported in an infant. Infants and children are in a state of high bone turnover. Therefore, they are prone to the imbalance of osteoblastic and osteoclastic activity that occurs with prolonged immobilization, leading to hypercalcemia. Here we present the case of an infant with hypercalcemia who presented with fatigue, irritability, and failure to thrive after prolonged immobilization. Therapeutic interventions were conservative and included hydration and increased mobility leading to complete resolution. This case highlights the importance of including this rare entity in a differential diagnosis of hypercalcemia as well as screening postsurgical patients with prolonged immobility for hypercalcemia.

Legionnaire's Disease and Acute Renal Failure: A Case Report and Literature Review
Boucree, Michael C.
1988-01-01
A case report is presented of a young man admitted to a general hospital with leukocytosis, elevated temperature, right lower lobe infiltrate, and confusion. A diagnosis of rhabdomyolysis, acute renal failure, and Legionnaire's disease was made. The patient subsequently had a respiratory arrest and died on the 29th hospital day. This triad is currently an enigma in the field of internal medicine. The diagnosis of each entity is elusive, and in many cases must be made by the astute clinician. Diagnostic features along with early intervention measures and their expected outcomes are discussed. Recognition of the interrelationship of these diseases, risk factors, and vague clinical presentations might allow further prospective intervention methods and diagnostic procedures to be undertaken to avoid the fatal consequences seen in this disease triad.

Oskar Fischer and the study of dementia
2009-01-01
The centenary of Alois Alzheimer's description of the case of Auguste Deter has renewed interest in the early history of dementia research. In his 1907 paper Alzheimer described the presence of plaques and tangles in one case of presenile dementia. In the same year, Oskar Fischer reported neuritic plaques in 12 cases of senile dementia. These were landmark findings in the history of research in dementia because they delineated the clinicopathological entity that is now known as Alzheimer's disease. Although much has been written about Alzheimer, only little is known about Fischer. The present article discusses Fischer's work on dementia in the context of his life and time. PMID:18952676
The Seven Sleepers: a folie à deux case originating from a religious-cultural belief.
Yazar, Menekse Sila; Erbek, Evrim; Eradamlar, Nezih; Alpkan, Latif
2011-11-01
Folie à deux is an uncommon psychiatric entity characterized by the transfer of delusional ideas and/or abnormal behavior from one person to another, or many others, who are in close contact with the primarily affected patient. In this paper we present a case of folie à deux, involving a married couple who suffered from a shared psychotic disorder with delusional interpretations of specific suras of the Koran. These mystical delusions were derived from the Anatolian legend of The Seven Sleepers. The case resulted in the death of the wife. This study illustrates the role of cultural and religious factors in folie à deux.
Stiff-person syndrome: a case report and review of the literature.
Egwuonwu, Steve; Chedebeau, Fernando
2010-12-01
We report a case of stiff-person syndrome associated with several autoimmune diseases. A 49-year-old male with type 1 diabetes presented with a 6-month history of muscle rigidity and spasms of his upper and lower extremities. Anti-glutamic acid decarboxylase 65 antibody was elevated at 609 nmol/L. Electromyography revealed continuous motor unit activity in agonist and antagonist muscles. He responded favorably to diazepam, baclofen, and intravenous immunoglobulin infusions. This case report describes stiff-person syndrome in association with pernicious anemia and diabetes mellitus. A review of the literature discusses the diagnosis and treatment of this rare entity.
Hereditary and non-hereditary microangiopathies in the young. An up-date.
Ringelstein, E Bernd; Kleffner, Ilka; Dittrich, Ralf; Kuhlenbäumer, Gregor; Ritter, Martin A
2010-12-15
In recent years, a considerable number of new sporadic or hereditary small artery diseases of the brain have been detected which preferably occur in younger age, below 45 years. Cerebral microangiopathies constitute an appreciable portion of all strokes. In middle aged patients, hereditary cerebral small vessel diseases have to be separated from sporadic degenerative cerebral microangiopathy which is mainly due to a high vascular risk load. Features of the following disorders and details how to differentiate them, are reviewed here, namely CADASIL, MELAS, AD-RVLC, HEMID, CARASIL, PADMAL, FABRY, COL4A1-related cerebral small vessel diseases and a Portuguese type of autosomal dominant cerebral small vessel disease (SVDB). The symptomatic overlap of the cerebral microangiopathies include also other distinctive non-hereditary diseases like posterior (reversible) encephalopathy and Susac's syndrome which are also described. Some of the microangiopathies described here are not only seen in the young but also in the elderly. The precise diagnosis has direct therapeutic implications in several of these entities. Cerebral microangiopathies cause recurring strokes and diffuse white matter lesions leading to a broad spectrum of gait disturbances and in most of these disorders cognitive impairment or even vascular dementia in the long term. Often, they also involve the eye, the inner ear or the kidney. Several typical imaging findings from illustrative cases are presented. The order in which these diseases are presented here is not dictated by an inner logic principle, because a genetically or pathophysiologically based classification system of all these entities does not exist yet. Some entities are well established and not unusual, whereas others have only been described in a few cases in total. Copyright © 2010 Elsevier B.V. All rights reserved.
Two cases of cerebral aneurysms in HIV+ children.
Fulmer, B B; Dillard, S C; Musulman, E M; Palmer, C A; Oakes, J
1998-01-01
Two cases of fusiform cerebral aneurysms in human immunodeficiency virus (HIV) positive children are presented. To our knowledge, only 9 patients with this association have been reported. One of our patients represents the first report of a patient with an aneurysm associated with varicella-zoster vasculitis. One patient presented with a subarachnoid hemorrhage, Hunt-Hess grade IV, and posed difficult surgical management. The other patient suffered a cerebral infarct with a resulting hemiparesis. The first patient had a ventriculostomy placed, initially improved, and subsequently died from rebleeding. The second patient improved with medical management. AIDS arteriopathy, and specifically fusiform aneurysms, are being increasingly reported. The various presentations of this surgically challenging entity in light of other AIDS-related syndromes pose difficult management decisions. On occasion, the intracranial aneurysm may be the initial form of presentation as was present in our first patient.
Large bladder calculus masking a stone in single-system ureterocele.
Bhaskar, Ved; Sinha, Rahul Janak; Purkait, Bimalesh; Singh, Vishwajeet
2017-06-14
Ureterocele in an elderly is a rare entity. The presence of stone within ureterocele along with a large bladder calculus is an even rarer presentation. This phenomenon has not been reported so far to the best of our knowledge. We present an unusual case of a large bladder calculus with a concomitant stone in the associated ureterocele. The diagnosis was missed in the first instance due to the masking effect by the larger bladder calculus. Herein, we discuss this case and its management. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

Tuberculous pseudoaneurysm of the aorta is rare and exposes patients to a very high risk of unpredictable rupture. To our best knowledge, only 32 cases have been reported related to all arterial systems from 1993 to 2013 in the literature. We report a 44-year-old male who presented with an aortic pseudoaneurysm and tuberculosis of the kidney and vertebrae. He underwent endovascular repair and antibiotic therapy for tuberculosis, combined with a bare stent implanted to seal endoleaks after endograft stenting. The postoperative course was uneventful and the patient recovered and lived well afterwards. Epidemiology, pathogenesis, presentation, management, and mortality of this entity were reviewed and discussed.
Bilateral recurrent discloation of the patella associated with below knee amputation: A case report
Batra, Sumit; Kumar, Ratnesh; Lenka, Prasanna
2005-01-01
Background Recurrent dislocation of the patella in patients with below knee amputation is a known entity. Abnormally high-riding patella (patella alta) and medial patellofemoral ligament insufficiency in these patients predisposes them to patellar instability. The established treatment of this problem is surgical realignment. Case presentation A 25 year old male patient with bilateral below knee amputation presented with bilateral recurrent dislocation of the patella while walking on knees on uneven ground. Clinical and radiographic studies showed patella alta. A simple shoe modification was used to treat this patient. Conclusions A simple shoe modification can be used to treat such a condition which is otherwise treated surgically. PMID:15717922
Acute Promyelocytic Leukemia Presenting with Severe Marrow Fibrosis.
Shah, Harsh; Bradford, Carol; Sayar, Hamid
2015-01-01
We report a case of acute promyelocytic leukemia (APL) presenting with severely fibrotic marrow. There are four other reports of similar cases in the literature. Our patient was treated with All-Transretinoic Acid- (ATRA-) containing induction chemotherapy, followed by consolidation and maintenance therapy. He achieved a complete morphologic remission with adequate count recovery in a timely fashion, and later a molecular remission was documented. The patient remains in molecular remission and demonstrates normal blood counts now more than 4 years after induction. Since the morphological appearance may not be typical and the bone marrow may not yield an aspirate for cytogenetic analysis, awareness of such entity is important to make a correct diagnosis of this potentially curable disease.
Isolated rhomboencephalosynapsis - a rare cerebellar anomaly.
Paprocka, Justyna; Jamroz, Ewa; Scieszka, Ewa; Kluczewska, Ewa
2012-01-01
Rhomboencephalosynapsis (RES, RS) is a unique entity usually recognized in infancy based on neuroimaging. Cerebellar fusion and absence of cerebellar vermis is often associated with supratentorial findings. Since now there are about 50 cases described worldwide, with approximately 36 patients diagnosed by MRI. The authors present the first in Poland case of this uncommon malformation and review the literature. The authors describe a 28-month-old-girl with microcephaly and proper psychomotor development. The family history was unrelevant. Based on MRI the congenital malformation of posterior fossa-rhombencephalosynapsis was confirmed Presented patient is a typical example of MRI usefulness especially in patients with RES. RES symptoms are mild and that is why the diagnosis is usually made only in adulthood.
Infantile masturbation and paroxysmal disorders.
Omran, Mohammadreza Salehi; Ghofrani, Mohammad; Juibary, Ali Ghabeli
2008-02-01
A recurrent paroxysmal presentation in children leads to different diagnoses and among them are neurologic and cardiac etiologies. Infantile masturbation is not a well known entity and cannot be differentiated easily from other disorders. Aim of this study is to elucidate and differentiate this condition from epileptic seizures. We report 3 cases of 10 to 30 mth old girls of infantile masturbation that their symptoms initiated at 2, 3 and 8 mth of age. These present with contraction and extension of lower extremities, scissoring of legs, perspiration, changing face color. In 2 cases body rocking and legs rubbing initiated then there after. Masturbation is one of the paroxysmal non-epileptic conditions of early infancy and is in differential diagnosis of epileptic seizures.

Anomalous left coronary artery from the pulmonary trunk (ALCAPA) presents in early infancy with a clinical picture of congestive heart failure with left ventricular (LV) dysfunction and mitral insufficiency. These manifestations of myocardial ischaemia may be masked in the presence of an associated patent ductus arteriosus (PDA) or ventricular septal defect (VSD) which prevents the fall of pulmonary artery pressures and allows perfusion of the anomalous coronary artery. We present a case of a patient with large PDA-associated ALCAPA and preserved LV function. The importance of such a finding lies in the fact that VSD closure or PDA ligation in such cases would unmask the ALCAPA.
Schwannomatosis of Cervical Vagus Nerve.
Abdulla, Faheem Ahmed; Sasi, M P
2016-01-01
Cervical vagal schwannoma is a rare entity among lesions presenting as a neck mass. They are usually slow-growing benign lesions closely associated with the vagus nerve. They are usually solitary and asymptomatic. Multiple schwannomas occurring in patients without neurofibromatosis (NF) are rare and have recently been referred to as schwannomatosis. Here, we present a case of a neck mass that had imaging features suggestive of vagal schwannoma and was operated upon. Intraoperatively, it was discovered to be a case of multiple vagal cervical schwannoma, all directly related to the right vagus nerve, and could be resected from the nerve in toto preserving the function of the vagus nerve. Final HPR confirmed our pre-op suspicion of vagal schwannomatosis.

Charles Bonnet syndrome: three cases in the emergency department.
Frost, Elizabeth J; Mottley, J Lawrence; Edlow, Jonathan A
2012-05-01
Charles Bonnet Syndrome (CBS) is a cause of visual hallucinations in elderly patients that is often unrecognized by emergency physicians and has a relatively benign course. As the population ages, it is likely that the number of cases of CBS will increase (and thus, the numbers of those who present to an Emergency Department [ED] will be increasing). The case reports presented in this article will facilitate the recognition of CBS by the emergency physician. We describe 3 patients who presented to one ED for visual disturbances and were diagnosed with CBS in a 4-month time period. Recognition of this unusual but stereotypical cause of visual disturbances facilitates an accurate diagnosis, and spares patients the time and expense of blood testing, imaging, and consultations. If emergency physicians begin to recognize this benign entity, we can provide improved (and safer) patient care with appropriate ED interventions. Copyright © 2012 Elsevier Inc. All rights reserved.

Geometry and mechanics of two-dimensional defects in amorphous materials
Moshe, Michael; Levin, Ido; Aharoni, Hillel; Kupferman, Raz; Sharon, Eran
2015-01-01
We study the geometry of defects in amorphous materials and their elastic interactions. Defects are defined and characterized by deviations of the material’s intrinsic metric from a Euclidian metric. This characterization makes possible the identification of localized defects in amorphous materials, the formulation of a corresponding elastic problem, and its solution in various cases of physical interest. We present a multipole expansion that covers a large family of localized 2D defects. The dipole term, which represents a dislocation, is studied analytically and experimentally. Quadrupoles and higher multipoles correspond to fundamental strain-carrying entities. The interactions between those entities, as well as their interaction with external stress fields, are fundamental to the inelastic behavior of solids. We develop analytical tools to study those interactions. The model, methods, and results presented in this work are all relevant to the study of systems that involve a distribution of localized sources of strain. Examples are plasticity in amorphous materials and mechanical interactions between cells on a flexible substrate. PMID:26261331
Central xanthoma of the jaw in association with Noonan syndrome.
Olson, Nicholas J; Addante, Rocco R; de Abreu, Francine B; Memoli, Vincent A
2018-05-01
Xanthomas are histiocytic lesions of the skin, soft tissue and bone and are generally considered to be reactive in nature. When they arise in the bones of the jaw, they are referred to as central xanthomas. New evidence supports the hypothesis that central xanthomas are a separate and distinct entity from their extragnathic counterparts. Noonan syndrome (NS) is an autosomal dominant disorder that has been associated with giant cell lesions which also commonly occur in the jaw. We present a case of a 15year-old-male with NS who presented with a radiolucent lesion of the mandible that on excision, was found to be a central xanthoma. Although giant cell lesions have been well described in NS, xanthomas of the jaw have not been reported. We will also discuss the entities that must be excluded prior to making a diagnosis of central xanthoma, as this can affect both treatment and follow up. Copyright © 2018. Published by Elsevier Inc.
Liver abscess in ancient Greek and Greco-Roman texts.
Papavramidou, Niki; Samara, Anastasia; Christopoulou-Aletra, Helen
2014-01-01
This paper presents liver abscesses, as studied in the ancient Greek and Greco-Roman bibliography. Numerous references concerning this entity can be found in the writings of the Hippocratic doctors (5th cent. B.C.), Archigenes of Apamea (1st cent. A.D.), Galen (2nd cent. A.D.), Aretaeus of Cappadocia (2nd cent. A.D), Oribasius (4th cent. A.D.), Theophilus Protospatharius (7th cent. A.D.), and Paulus Nicaeensis (7th-10th cent. A.D.). In most cases the clinical manifestations, the prognosis and the method of treatment are presented. In all ancient writings we studied, the rupture of a liver abscess is also part of the main theme. In specific, the path that the fluid would follow after a rupture was considered to be a main prognostic factor, i.e. if the fluid "coursed into the stomach", the patient would definitely die. In this work, an attempt is also made to correlate the ancient descriptions to modern medical entities, such as amebic or pyogenic liver abscess.

Spinal cord herniation following surgery is an extremely uncommon clinical condition with very few reports in published literature. This condition usually occurs as a spontaneous idiopathic phenomenon often in the thoracic spine or following a scenario of post traumatic spinal cord/nerve root injury. Rarely has it been reported following spinal cord tumor surgery. To document a case of cervical spinal cord herniation as a late onset complication following spinal cord tumor surgery with an atypical presentation of monoparesis. Case report. We describe the clinical presentation, operative procedure, post operative outcome and review of literature of this rare clinical condition. A 57-year-old man presented with right upper limb monoparesis due to a spinal cord herniation 6 years after a cervical intradural meningioma excision. The patients underwent surgery to reduce the herniation and duroplasty with subsequent complete resolution of symptoms. Spinal cord herniation must be considered as differential diagnosis in scenarios of spinal cord tumor excision presenting with late onset neurological deficit. These cases may present as paraparesis, Brown-sequard syndrome and rarely as in our case as monoparesis.

In practices, some cases of salivary basal cell tumors that consist mainly of cribriform growth pattern are difficult to differentiate from adenoid cystic carcinoma (AdCC). Identification of reliable molecular biomarkers for the differential diagnosis between them is required. Twenty-two cases of cribriform salivary basal cell tumors (at least 10% cribriform pattern present in each tumor) comprising 18 cases of basal cell adenoma (BCA) and four cases of basal cell adenocarcinoma (BcAC) were collected between 1985 and 2008. Twenty cases of cribriform AdCC were retrieved from our archives. MYB protein expression and gene abnormalities were detected in all cases by immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) analyses, respectively. Neither MYB protein nor split genes were detected in any of the cases of cribriform basal cell tumors, while 55% (11/20) of cases of cribriform AdCC had MYB protein expression. High MYB expression was detected in 81.8% (9/11) cases, while low expression was found in the remaining cases. FISH analysis indicated that nine AdCC tumors with high MYB protein expression were split gene-positive, while MYB gene splitting was not detected in the 11 cases with low or absent MYB protein expression. The molecular changes in AdCC differ from those associated with cribriform basal cell tumors, which further confirms that cribriform basal cell tumors and AdCC are two distinct tumor entities. Simultaneous detection of MYB protein expression and the associated molecular changes could be beneficial in differentiating salivary cribriform basal cell tumors from AdCC. © 2015 John Wiley & Sons A/S.

Melorheostosis is a rare benign disease of cortical bone most frequently presenting as peripheral hyperostosis with a characteristic "melting wax" appearance on conventional radiographs. The disease most frequently affects the appendicular skeleton and is seen only rarely in the craniofacial bones. We discuss a case of melorheostosis in the nasal cavity and skull base with an atypical radiographic appearance and suggest findings that may differentiate craniofacial melorheostosis from more common entities in this region.
Congenital Eccrine Angiomatous Hamartoma: A Rare Entity Revisited
Mendiratta, Vibhu; Malik, Meenu; Agrawal, Mahima; Jain, Manjula; Gupta, Brijnandan
2018-01-01
Eccrine angiomatous hamartoma (EAH) is a rare benign malformation characterized by eccrine and vascular components. It usually presents at birth or during early infancy or childhood on lower extremities as a nodule or plaque. We report a case of asymptomatic tumoral swelling over the left leg in a 5-month-old Indian infant since birth. This was diagnosed as EAH on histopathology and confirmed on immunohistochemistry.

On the basis of two cases the differences between the plaque-like variant of dermatofibrosarcoma protuberans (PDFSP) and the plaque-like dermal fibromatosis (synonym: dermatomyofibroma; PDF) are presented. PDFSP and PDF are two clinically very similar dermal fibrous proliferations, but differentiation is important because of their different therapy and prognosis. Histologically and immunohistochemically PDFSP and PDF can be recognized as separate entities.

White piedra of scalp hair is considered a rare entity. We report three cases of this disorder all of whom presented with nodules on the hair. Potassium hydroxide preparations of the hair revealed clustered arthrospores and mature, easily detachable nodules. Cultures grew Trichosporon inkin in 2 patients and Trichosporon mucoides in one patient. Both these fungi are unusual causes of white piedra.

Gastric perforation (GP) in neonates is a rare entity with high mortality. Although the etiology is not completely understood, it mostly occurs in premature neonates on assisted ventilation. Combination of duodenal atresia and gastric perforation is very rare. We present a case duodenal atresia who developed gastric perforation after operetion for duodenal atresia. Analysis of the patient medical record and histology report did not reveal the etiology of the perforation.

Solitary plaques developed on the sun-exposed and damaged skin of five elderly, fair-skinned individuals. The lesions, erythematous to bluish confluent nodules and plaques with a cribriform appearance and comedone-like structures, presented a distinctive histologic picture of dilated, keratin-filled follicles within a matrix of amorphous, damaged collagen. We believe these cases demonstrate a distinct entity within the realm of actinic dermatoses, for which the name "actinic comedonal plaque" seems appropriate.
Congenital esophageal stenosis: the differential diagnosis and management.

Congenital esophageal stenosis (CES) is a rare congenital abnormality that is difficult to diagnose and often masquerades as other types of structural esophageal disease. We report three cases of CES with different presenting symptoms. We advocate for balloon dilation as the preferred first approach to therapeutic intervention. CES is an important clinical entity in the evaluation of pediatric esophageal disorders and should be suspected in young infants with dysphagia.

A telepresence robot system realized by embedded object concept
NASA Astrophysics Data System (ADS)
Vallius, Tero; Röning, Juha
2006-10-01
This paper presents the Embedded Object Concept (EOC) and a telepresence robot system which is a test case for the EOC. The EOC utilizes common object-oriented methods used in software by applying them to combined Lego-like software-hardware entities. These entities represent objects in object-oriented design methods, and they are the building blocks of embedded systems. The goal of the EOC is to make the designing embedded systems faster and easier. This concept enables people without comprehensive knowledge in electronics design to create new embedded systems, and for experts it shortens the design time of new embedded systems. We present the current status of a telepresence robot created with second-generation Atomi-objects, which is the name for our implementation of the embedded objects. The telepresence robot is a relatively complex test case for the EOC. The robot has been constructed using incremental device development, which is made possible by the architecture of the EOC. The robot contains video and audio exchange capability and a controlling system for driving with two wheels. The robot is built in two versions, the first consisting of a PC device and Atomi-objects, and the second consisting of only Atomi-objects. The robot is currently incomplete, but most of it has been successfully tested.

Fungal abscesses of the parotid gland are rare, and cases arising within parotid neoplasms have not been described previously. This report conveys our experience managing such an entity, which is further distinguished by its occurrence in an immunocompetent host. A 59-year-old man experienced multiple recurrences of a parotid fungal abscess requiring repeated drainage procedures. Definitive excision ultimately demonstrated Candida glabrata infecting a Warthin tumor. This case is the first report of a parotid neoplasm presenting as a fungal abscess. It contributes to the scant literature on fungal abscesses of the parotid, which previously has only been described in debilitated hosts and without an associated neoplasm. The case also expands the spectrum of disease associated with C. glabrata. Warthin tumor may be an occult etiology for a parotid fungal abscess, and definitive diagnosis and therapy may require parotidectomy.
Guillain-Barre syndrome complicating chikungunya virus infection.
Agarwal, Ayush; Vibha, Deepti; Srivastava, Achal Kumar; Shukla, Garima; Prasad, Kameshwar
2017-06-01
Chikungunya virus (CHIKV) is a mosquito-borne alphavirus which presents with symptoms of fever, rash, arthralgia, and occasional neurologic disease. While outbreaks have been earlier reported from India and other parts of the world, the recent outbreak in India witnessed more than 1000 cases. Various systemic and rarely neurological complications have been reported with CHIKV. We report two cases of Guillain-Barré syndrome (GBS) with CHIKV. GBS is a rare neurological complication which may occur after subsidence of fever and constitutional symptoms by several neurotropic viruses. We describe two cases of severe GBS which presented with rapidly progressive flaccid quadriparesis progressing to difficulty in swallowing and breathing. Both required mechanical ventilation and improved partly with plasmapharesis. The cases emphasize on (1) description of the rare complication in a setting of outbreak with CHIKV, (2) acute axonal as well as demyelinating neuropathy may occur with CHIKV, (3) accurate identification of this entity during outbreaks with dengue, both of which are vector borne and may present with similar complications.
Biological entities isolated from the stratosphere (22-27km): case for their space origin

Biological entities were isolated at a height of between 22-27 km in the stratosphere. Sampling of this region was carried out in the UK in July 2013 using a relatively simple low-cost balloon-borne sampler carrying aseptically clean scanning electron microscope stubs onto which aerosols were directly captured. The entities varied from a presumptive colony of ultra-small bacteria to two unusual individual organisms - part of a diatom frustule and a 200 micron-sized particle mass interlaced with biological filaments. Biological entities of this nature have not previously been reported occurring in the stratosphere; their likely origin is discussed and we provide arguments to support our view that such biological entities may have arrived from space. The new data gives strong confirmation of the Hoyle-Wickramasinghe theory of cometary panspermia.

Epithelial sheath neuroma is a rarely recognized but established entity in the medical literature. First described in 2000 by Requena et al, there have only been 7 published cases to date, mostly in female patients and presenting as symptomatic solitary lesions on the back without a known history of trauma. In 2006, Beer et al described and reviewed a dozen cases in which epithelial sheath neuroma-like features were seen in the advent of a surgical procedure, which was termed "re-excision perineural invasion" and attributed to possible eccrine duct implantation during surgery. Our case is a 66-year-old male patient who underwent an excision of a melanocytic neoplasm in which a reactive epithelial sheath neuroma was incidentally discovered in the excision specimen, adjacent to the biopsy site cicatrix. Histologically, there was benign cutaneous nerve hyperplasia with a proliferation of squamous epithelium in intimate apposition to the nerve bundles in the superficial dermis. We postulate that the process active in the formation of re-excision perineural invasion is the same as in epithelial sheath neuroma and that minor trauma not appreciable on histologic examination is responsible in the latter entity. We performed IL-6 staining and documented that IL-6 was upregulated at the interface of the nerve and reactive epithelium, but was absent in nerves distant from the site of surgery, suggesting that IL-6 may be essential to the lesion's development. The recognition of reactive epithelial sheath neuroma including the subcategory of re-excision perineural invasion is crucial for the dermatopathologist to prevent mislabeling this reactive entity as a perineural squamous cell carcinoma, which has clinical consequences for the patient such as wider re-excision and radiation treatment. Additionally, we have identified a potential pathophysiologic basis for this lesion.
Safety Case Development as an Information Modelling Problem
NASA Astrophysics Data System (ADS)
Lewis, Robert
This paper considers the benefits from applying information modelling as the basis for creating an electronically-based safety case. It highlights the current difficulties of developing and managing large document-based safety cases for complex systems such as those found in Air Traffic Control systems. After a review of current tools and related literature on this subject, the paper proceeds to examine the many relationships between entities that can exist within a large safety case. The paper considers the benefits to both safety case writers and readers from the future development of an ideal safety case tool that is able to exploit these information models. The paper also introduces the idea that the safety case has formal relationships between entities that directly support the safety case argument using a methodology such as GSN, and informal relationships that provide links to direct and backing evidence and to supporting information.
Mollaret meningitis: case report with a familial association.
Jones, Christopher W; Snyder, Graham E
2011-09-01
Mollaret meningitis is a syndrome characterized by recurrent bouts of meningitis that occur over a period of several years in an affected patient. Also known as recurrent lymphocytic meningitis, this entity involves repeated episodes of headache, stiff neck, fever, and cerebrospinal fluid pleocytosis. Herpes simplex virus type 2 is the most frequently implicated causative agent, and treatment involves the use of antiviral medications. We describe a case of Mollaret meningitis in a 47-year-old man who presented to the emergency department with his eighth episode of meningitis during a period of 20 years. Cerebrospinal fluid polymerase chain reaction testing for herpes simplex virus type 2 was positive, and further testing excluded other common viral, bacterial, and inflammatory causes of meningeal irritation. The patient's family history was significant for a brother who also had multiple episodes of aseptic meningitis during a period of several years. This represents the first published report of a possible familial association involving Mollaret meningitis. It is likely that Mollaret meningitis is underrecognized among emergency physicians, and improved recognition of this entity may limit unwarranted antibiotic use and shorten or eliminate unnecessary hospital admission.

Dermoid cyst of the spermatic cord is a very rare clinical entity with only a few cases reported in the literature so far. We herein describe an extremely rare case of a large dermoid cyst of the spermatic cord measuring 8.5 x 5 x 5 cm in a young patient who presented with clinical manifestations of an incarcerated inguinal hernia. After the cyst excision, a diffuse direct hernia became apparent and a Lichtenstein polypropylene mesh repair was performed. Direct hernia was likely the result of chronic pressure on the inguinal floor maintained by the large cyst. We conclude that although very rare, dermoid cyst of the spermatic cord should be considered as a part of the differential diagnosis in patients presenting with an irreducible inguinal mass of a long course.
Role of endoscopy in recalcitrant intraventricular tuberculoma-innovative novel treatment adjunct.
Udayakumaran, Suhas; Nair, Prakash; Kumar, Anil; Panikar, Dilip
2014-09-15
Introduction. Intraventricular tuberculomas are rare entities. To the best of our knowledge, only 14 cases have been reported in English literature. Medical management of cerebral tuberculomas is well accepted. Intraventricular tuberculomas may be recalcitrant for unclear reasons. An effective management protocol for this entity is unclear. To the best of our knowledge, the definitive indication, timing, and possible role of surgery in these lesions have not been discussed in literature. Materials and methods. A 27-year-old nursing professional who was undergoing treatment for miliary tuberculosis at another center presented to us in 2008 with right hemiparesis, deteriorating vision, and progressive decline in consciousness. In addition to antituberculous therapy (ATT), she underwent multiple CSF diversion procedures for the obstructive hydrocephalus secondary to a recalcitrant third ventricular tuberculoma. Finally, she underwent endoscopic decompression of the lesion with a very good clinical response at 1-year follow-up. Discussion. We discuss a patient with recalcitrant intraventricular tuberculoma managed using neuroendoscopy along with the standard antituberculous therapy. We also discuss in detail the technique we utilized for endoscopic management of this lesion. Conclusion. Being a rare entity, a consensus for management of these lesions is not possible, but we have demonstrated that neuroendoscopic management of these rare entities is an option giving the advantage of definitive diagnosis when required, hastening the resolution, and clearing the CSF pathway.
Data Type Registry - Cross Road Between Catalogs, Data And Semantics

As more data become accessible online, the opportunity is increasing to improve search for information within datasets and for automating some levels of data integration. A prerequisite for these advances is indexing the kinds of information that are present in datasets and providing machine actionable descriptions of data structures. We are exploring approaches to enabling these capabilities in the EarthCube DigitalCrust and Data Discovery Hub Building Block projects, building on the Data type registry (DTR) workgroup activity in the Research Data Alliance. We are prototyping a registry implementation using the CNRI Cordra platform and API to enable 'deep registration' of datasets for building hydrogeologic models of the Earth's Crust, and executing complex science scenarios for river chemistry and coral bleaching data. These use cases require the ability to respond to queries such as: What are properties of Entity X; What entities include property Y (or L, M, N…), and What DataTypes are about Entity X and include property Y. Development of the registry to enable these capabilities requires more in-depth metadata than is commonly available, so we are also exploring approaches to analyzing simple tabular data to automate recognition of entities and properties, and assist users with establishing semantic mappings to data integration vocabularies. This poster will review the current capabilities and implementation of a data type registry.

MRI appearance of massive renal replacement lipomatosis in the absence of renal calculus disease
Fitzgerald, E; Melamed, J; Taneja, S S; Rosenkrantz, A B
2011-01-01
Renal replacement lipomatosis is a rare benign entity in which extensive fibrofatty proliferation of the renal sinus is associated with marked renal atrophy. In this report, we present a case of massive renal replacement lipomatosis demonstrated on MRI. The presentation was atypical given an absence of associated renal calculus disease, and an initial CT scan was interpreted as suspicious for a liposarcoma. The differential diagnosis and key MRI findings that served to establish this specific diagnosis are reviewed. Histopathological correlation is also presented, as the patient underwent nephroureterectomy. PMID:21257835
Current insights into the aetiology of adolescent idiopathic scoliosis.

Scoliosis occurs in about 0.2-0.6% of the general population. In the majority of cases the cause of this entity remains mostly unidentified. The search for the causes covers almost all aspects of its possible origin. We collected and systematised the contemporary theories and concepts concerning the aetiology of adolescent idiopathic scoliosis. Genetic and hereditary factors are commonly accepted as possible causes; however, the identification of the single gene responsible for the development of this condition seems impossible, which suggests multifactorial mechanism of its formation. Dysfunctions of the nervous system are recognised risks related to the development of scoliosis, but they are classified as belonging to a separate aetiological category. Scoliosis develops at the quickest rate during the child's growth spurt, which prompted the research on the role of the growth hormone in scoliosis aetiology. Melatonin is another hormone that is studied as a possible factor involved in development of this entity. In cases of progressive scoliosis, increased activity of calmodulin-a protein that regulates the levels of calcium ions-has been observed. The scientists have characterised numerous qualitative and quantitative changes in the composition of the tissue of intervertebral discs, spinal ligaments and paraspinal muscles. Some of the theories, explaining the nature of this entity, presented in this review seem to have only a purely theoretical value; their proliferation only confirms the fact that the actual nature of this condition has not been unveiled yet, and suggests its multifactorial aetiology.

Purulent pericarditis is an uncommon entity, which is, in very rare cases, associated to infection of the aorta. We present the case of a 42-year-old male patient, who was admitted to hospital complaining of tiredness, diarrhea and leg edema. Clinical examination revealed a hypotensive and obviously shocked patient. He was ultimately diagnosed with a rare combination of purulent pericarditis followed by false aneurysm of the ascending aorta. He was successfully treated by surgical pericardial drainage, replacement of the ascending aorta and antibiotics. Mycotic aneurysms can rarely be associated with purulent pericarditis. Our literature review shows that there are two mechanisms explaining this association and that in most of the published cases infective endocarditis could not be demonstrated.

We present a cytogenetic clonal evolution that correlates morphological and immunological shifts in a case of a patient with a t(4;11) (q21;q23) acute leukemia. We take this opportunity to review 146 cases reported so far, with special reference to morphology, immunophenotyping, cytogenetics, clinical characteristics and evolution. Particular features are underlined, and prognosis, leukemic stem cell origin, chromosomal breakpoints and genes involved are discussed. A relationship between this type of leukemia and exposure to carcinogens is suggested by a high rate of secondary leukemia in adults and a high frequency in newborns and infants.

2017-07-01
Multinodular and vacuolating neuronal tumor is a recently described seizure-associated entity with overlapping features of a malformative and neoplastic process. We report a case of multinodular and vacuolating neuronal tumor in a 29-year-old man with a history of recent headaches and complex partial seizures. Neuroimaging revealed a nonenhancing, T2 and T2 fluid-attenuated inversion recovery hyperintense multinodular lesion in the right temporal lobe. Lesional tissue demonstrated well-demarcated nodules of ganglioid cells with vacuolation of both the perikarya and the fibrillary neuropil-like background. The ganglioid cells showed weak cytoplasmic reactivity for synaptophysin and were nonreactive for neurofilament and chromogranin. CD34-positive stellate cells were present within the nodules. A 50-gene next-generation sequencing panel did not identify any somatic mutations in genomic DNA extracted from the tumor.
Congenital anomalies of the optic nerve
Amador-Patarroyo, Manuel J.; Pérez-Rueda, Mario A.; Tellez, Carlos H.
2014-01-01
Congenital optic nerve head anomalies are a group of structural malformations of the optic nerve head and surrounding tissues, which may cause congenital visual impairment and blindness. Each entity in this group of optic nerve anomalies has individually become more prevalent as our ability to differentiate between them has improved due to better characterization of cases. Access to better medical technology (e.g., neuroimaging and genetic analysis advances in recent years) has helped to expand our knowledge of these abnormalities. However, visual impairment may not be the only problem in these patients, some of these entities will be related to ophthalmologic, neurologic and systemic features that will help the physician to identify and predict possible outcomes in these patients, which sometimes may be life-threatening. Herein we present helpful hints, associations and management (when plausible) for them. PMID:25859137

Austrian syndrome-the combination of meningitis, pneumonia and infective endocarditis due to Streptococcus pneumoniae infection, is a rare entity. In literature only a few hundreds of cases are reported but surprisingly we did not find any report on Austrian syndrome in or from Bangladesh. We report the case history of a middle aged Bangladeshi diabetic man, who had fever, cough, shortness of breath and altered mentation. He had tachycardia, bi-basal lung crepitations, new cardiac murmurs and meningism. Diagnostic work-up revealed Austrian syndrome. Because of the rarity of the condition, this case is reported. A case of pneumococcal pneumonia or meningitis should raise suspicion of concomitant endocarditis and Austrian syndrome, specially if there is heart failure, as early recognition and treatment may appear life-saving.

Background Patients with diabetic neuropathy (DPN) and fibromyalgia differ substantially in pathogenetic factors and the spatial distribution of the perceived pain. We questioned whether, despite these obvious differences, similar abnormal sensory complaints and pain qualities exist in both entities. We hypothesized that similar sensory symptoms might be associated with similar mechanisms of pain generation. The aims were (1) to compare epidemiological features and co-morbidities and (2) to identify similarities and differences of sensory symptoms in both entities. Methods The present multi-center study compares epidemiological data and sensory symptoms of a large cohort of 1434 fibromyalgia patients and 1623 patients with painful diabetic neuropathy. Data acquisition included standard demographic questions and self-report questionnaires (MOS sleep scale, PHQ-9, PainDETECT). To identify subgroups of patients with characteristic combinations of symptoms (sensory profiles) a cluster analysis was performed using all patients in both cohorts. Results Significant differences in co-morbidities (depression, sleep disturbance) were found between both disorders. Patients of both aetiologies chose very similar descriptors to characterize their sensory perceptions. Burning pain, prickling and touch-evoked allodynia were present in the same frequency. Five subgroups with distinct symptom profiles could be detected. Two of the subgroups were characteristic for fibromyalgia whereas one profile occurred predominantly in DPN patients. Two profiles were found frequently in patients of both entities (20-35%). Conclusions DPN and fibromyalgia patients experience very similar sensory phenomena. The combination of sensory symptoms - the sensory profile - is in most cases distinct and almost unique for each one of the two entities indicating aetiology-specific mechanisms of symptom generation. Beside the unique aetiology-specific sensory profiles an overlap of sensory profiles can be found in 20-35% of patients of both aetiologies. PMID:21612589
Chromoblastomycosis due to Fonsecaea pedrosoi: an old wine in a rare bottle.
Khan, Sadia; Kumar, Anil; Vinod, Vivek; Prabhakar, Vivek; Eapen, Malini; Thomas, Jacob; Dinesh, Kavitha; Karim, Shamsul
2015-03-15
Chromoblastomycosis is a chronic subcutaneous mycosis commonly caused by Fonsecaea, Phialophora, and Cladophialophora spp. Out of these, Fonsecaea pedrosoi is the most common etiological agent, implicated in 70%-90% of the cases reported worldwide. The histopathological diagnosis of chromoblastomycosis is based on visualization of medlar or sclerotic bodies in the tissue. These sclerotic bodies divide by planar division. Rarely, budding is seen in these sclerotic bodies. As this entity can be confused with phaeohyphomycosis, it is important to be aware of such a presentation also. We report two cases of chromoblastomycosis that showed budding sclerotic bodies.
Munchausen's syndrome in obstetrics and gynecology: a review.
Edi-Osagie, E C; Hopkins, R E; Edi-Osagie, N E
1998-01-01
Nineteen review articles and case reports were identified and reviewed through August 1996 in Index Medicus, MEDLINE (English and foreign language), conference abstracts, and bibliographies from major articles, textbooks and reviews, to review Munchausen's syndrome in obstetrics and gynecology. In these 19 articles, 30 reported cases of the syndrome were identified in obstetric and gynecological patients. This survey found that the presentation varied, diagnosis was difficult, treatment was unclear, and the economic burden was enormous. Increasingly, this syndrome is becoming an important clinical entity in the specialty, and requires a high index of suspicion to improve detection and optimize treatment.

Synovial sarcoma is a rare entity to be encountered in the head and neck region and is always a challenge in terms of diagnosis, treatment planning and reconstruction of the surgical defect. In our case, we faced a similar challenge for diagnosis and also have ventured for lateral trapezius flap as a new reconstructive option for such bulky tumour defects. We hereby present a 25-year old male patient with monophasic synovial sarcoma of posterior pharyngeal wall. The radiological and clinicopathological features along with various diagnostic tests and treatment options are discussed.
Heterotaxy syndrome with severe pulmonary hypertension in an adult.
Brandenburg, Vincent M; Krueger, Stefan; Haage, Patrick; Mertens, Peter; Riehl, Jochen
2002-05-01
Heterotaxy syndrome is a rare clinical entity in adults, characterized by situs ambiguus, congenital heart defects, and splenic malformations. We report the case of an adult with heterotaxy syndrome (including situs ambiguus, bilateral superior vena cava, hypoplastic right-sided spleen and portosystemic shunts) presenting with dyspnea due to severe pulmonary hypertension. Vasodilatory therapy was initiated, leading to marked reduction of clinical symptoms. This case exhibits 2 particular and partially novel features: primary diagnosis of heterotaxy syndrome may be delayed until adulthood, and heterotaxy syndrome may be associated with pulmonary hypertension, possibly on the basis of longstanding portosystemic shunts.
Paramolar – A supernumerary molar: A case report and an overview
Nayak, Gurudutt; Shetty, Shashit; Singh, Inderpreet; Pitalia, Deepti
2012-01-01
Paramolar is a supernumerary molar usually small and rudimentary, most commonly situated buccally or palatally to one of the maxillary molars. Paramolar is a developmental anomaly and has been argued to arise from a combination of genetic and environmental factors. Reports of this entity are rarely found in the dental literature. This article presents a case report of an unusual occurrence of a paramolar in the maxilla in otherwise a healthy individual. In addition, literature review, prevalence, classification, etiology, complications, diagnosis, and therapeutic strategies that may be adopted when supernumeraries occurs have been discussed.

2015-04-01
Intraosseous haemangiomas (IOHs) are benign vascular bone tumours that account for 1% of all primary bone tumours. They are most frequently seen in the vertebrae and skull, and are rarely found in long bones. Herein, we present an uncommon case of a 25-year-old woman with a solitary IOH that occupied the left femoral neck. We describe the clinical, radiological and histological details of the case, as well as the three-year outcome of the surgical treatment, which successfully preserved the femoral head. We also conducted a review of the literature on this uncommon entity.

I believe that the transient blindness which presented Alexander the Great after his being wounded on his head and/or his neck by a stone from a catapult during the siege of Cyropolis (329 BC) was in all probability a case of transient cortical blindness that was recognized as a special entity in the 1960s. I reached this conclusion after the comparative study of the Emperor's clinical picture provided by ancient texts, especially those of Plutarch and Quintus Curtius Rufus, with that of a modern medical bibliography.

2014-01-01
We present the case of a 58-year-old woman who had large lipomatous hypertrophy of the interventricular septum, a condition that is reported very infrequently. Preoperative cardiac magnetic resonance images revealed an inhomogeneous, infiltrating mass that was suppressed in fat-suppression mode. The extensive mass was causing right ventricular dysfunction, so we excised it through a right ventricular approach. The findings on histologic analysis of the mass were consistent with lipomatous hypertrophy. The patient died of septic shock on the 28th postoperative day. In addition to the patient's case, we discuss the characteristics and diagnosis of this rare entity. PMID:24808791

A case of sclerosing mucoepidermoid carcinoma with eosinophilia of the thyroid gland is described. The patient, a 32 year-old female with Hashimoto's thyroiditis, presented with a 4 cm nodule of the right lobe of the thyroid gland. The tumour was constituted by squamoid cords infiltrating a dense fibro-jaline stroma rich in eosinophils. The patient is alive and well 14 months after surgery. The literature is briefly reviewed and the differential diagnosis is discussed. In the Author's opinion, sclerosing mucoepidermoid carcinoma with eosinophilia of the tyroid is a well defined clinicopathological entity.
Autoimmune pancreatitis: case series and review of the literature.
Shakov, Rada; DePasquale, Joseph R; Elfarra, Hossam; Spira, Robert S
2009-01-01
Autoimmune pancreatitis (AuP) is a chronic pancreatic inflammation secondary to an underlying autoimmune mechanism. After early reports of a particular type of pancreatitis associated with hypergammaglobulinemia, others asserted that there is an autoimmune mechanism involved in some patients with chronic pancreatitis. In 1995 AuP was first described as a distinct clinical entity. Since then, there have been many documented cases of AuP in Japan, and now, perhaps due to increased awareness, more cases are being reported in Europe and the United States. Herein we present our experience with 3 cases of AuP and we review the relevant literature. These 3 cases demonstrate the difficulties that exist in making the diagnosis of AuP and the impact that the diagnosis can have on patient management.

Congenitally corrected transposition of the great arteries is a rare form of CHD. Situs inversus is a much less common variant of a congenitally corrected transposition of the great arteries. In rare cases, transposition events may be accompanied by various cardiac anomalies. However, situs inversus patients with congenitally corrected transposition, single coronary artery anomaly, and atrioventricular block together have not been reported previously. This combination of abnormalities is presented as a first in the literature.
Paraspinal tuberculosis mimicking malignancy.
Alherabi, Ameen Z; Marglani, Osama A; Gazzaz, Malak J; Abbas, Mohammed M
2013-12-01
Tuberculosis (TB) of the paraspinal muscles is a rare clinical entity. We present a case of an 18-year-old, Saudi male patient presenting with the clinical picture of a paraspinal mass that turned out to be paraspinal TB. It originated from the paraspinal tissues and muscles, and invaded the C6 and C7 vertebrae. Initially, it was highly suspicious for malignancy. A biopsy confirmed the diagnosis of TB, and the patient was treated successfully with anti-TB therapy. It is important to be aware that paraspinal TB can mimic malignancy.

Kikuchi-Fujimoto disease (KFD) is a benign and self-limited disease of unknown etiology that affects mainly young women. It presents with localized lymphadenopathy, usually cervical, accompanied with fever, night sweats, and leucopenia. KFD has been rarely described in association with autoimmune disorders, mainly systemic lupus erythematosus (SLE). We report the case of a young patient presenting with KFD coinciding with SLE. The association of KFD and SLE is reviewed. Moreover, a possible pathogenetic role of Ebstein-Barr virus linking the two clinical entities is discussed.
A case presentation of bilateral simultaneous Bell's palsy.

Bilateral simultaneous facial paralysis is an extremely rare clinical entity. Unlike the unilateral form, bilateral facial paralysis seldom falls into Bell's category. It is most often a special finding in a symptom complex of a systemic disease; many of them are potentially life-threatening, and therefore the condition warrants urgent medical intervention. Lyme disease, Guillian-Barre syndrome, Bell's palsy, leukemia, sarcoidosis, bacterial meningitis, syphilis, leprosy, Moebius syndrome, infectious mononucleosis, and skull fracture are the most common cause of bilateral facial paralysis. Here we present a 16-year-old patient with bilateral simultaneous Bell's palsy.

Neutrophil-rich CD30+ anaplastic large-cell lymphoma (ALCL) is a rare pathological entity without distinct clinical behavior. Twelve cases of neutrophil-rich CD30+ anaplastic large-cell lymphoma (ALCL) have been reported, three of them were HIV-infected patients. All these reports stressed the presence of neutrophil infiltration as a new morphologic feature of CD30+ ALCL. Only one case of cutaneous involvement presented with microabscess formation. We describe a case of neutrophil-rich CD30+ ALCL in an AIDS patient with a clinical picture determined by the massive neutrophil infiltration of the tumor without necrosis nor local infection, but with the formation of abscesses.
Concurrent Acute Retinal Necrosis in a Patient With Iridocorneal Endothelial Syndrome.
Vignesh, A P; Srinivasan, Renuka
2016-11-01
To report a rare case of concurrent acute retinal necrosis in a patient with iridocorneal endothelial syndrome (ICE). Case report. A 42-year-old woman showed acute diminution of vision in the right eye. Her fundus examination revealed features of acute retinal necrosis. She had also experienced gradual diminution of vision in her left eye for 5 years. The examination of her left eye revealed corneal edema with mild corectopia and increased intraocular pressure with abnormal endothelium on specular microscopy pointing to a diagnosis of ICE. This is a rare case where concurrent acute retinal necrosis and ICE syndrome are present in the same patient, possibly pointing to a common viral etiology causing both entities.
Central granular cell odontogenic tumor: Report of an unusual case.
Madan, Mani; Chandra, Shaleen; Raj, Vineet; Madan, Rohit
2016-01-01
Central granular cell odontogenic tumor (CGCOT) is an unusual benign odontogenic neoplasm characterized by the presence of granular cells associated with apparently inactive odontogenic epithelium. These tumors tend to occur in the posterior mandible and usually present as well-defined unilocular or multilocular radiolucent lesions. So far, only <40 cases of CGCOT have been described in the literature under various terminologies. Though these tumors were not considered as distinct entity in the recent WHO classification of odontogenic tumors, long-term follow-up is recommended as malignant counterpart of CGCOT has already been reported. The main aim of this article is to report an additional case of CGCOT to the literature, occurring in a 73-year-old male.

Although it is not a pathologically significant entity, cases of azygos lobe (AL) are interesting due to the difficulty of performing video-assisted thoracoscopic surgery (VATS) procedures in the affected patients and the presence of a congenital malformation. Currently, videothoracoscopic surgery has advanced to such a level that most thoracic procedures can be performed with video assistance. However, some technical difficulties may arise in cases with anatomical anomalies such as AL. This report presents the case of a patient with an azygos lobe who underwent videothoracoscopic lung resection due to the presence of non-small-cell lung carcinoma in the upper lobe of the right lung.

Ovarian hyperstimulation, hyperprolactinaemia and LH gonadotroph adenoma.
Castelo-Branco, Camil; del Pino, Marta; Valladares, Esther
2009-08-01
This report considers a highly exceptional case of ovarian hyperstimulation syndrome due to a gonadotroph adenoma secreting LH in a 31-year-old patient who presented with amenorrhoea and galactorrhoea syndrome and a complex bilateral ovarian mass. Magnetic resonance imaging revealed a pituitary adenoma, and laboratory tests corroborated the hyperprolactinaemia without other hormonal pituitary abnormalities. Ovarian hyperstimulation syndrome due to a gonadotroph adenoma with normal gonadotrophins is extremely rare. Most of the described cases are caused by FSH adenomas. Due to the originality of the case, it was considered useful for understanding the management of this entity, and it is proposed that LH adenomas should also be considered in the differential diagnosis of patients with spontaneous ovarian hyperstimulation syndrome.
Hemophagocytic lymphohistiocytosis secondary to T-cell/histiocyte-rich large B-cell lymphoma

2014-01-01
Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening clinical syndrome characterized by dysregulation of the immune system. Impaired function of cytotoxic T cells and natural killer cells is often seen, and T-cell malignancies represent most cases of lymphoma-associated HLH. HLH associated with B-cell lymphoma is rare. We describe a case of a 30-year-old man who presented with fever, splenomegaly, and hyperferritinemia. Bone marrow biopsy revealed T-cell/histiocyte-rich large B-cell lymphoma, a rare, aggressive B-cell malignancy. This case highlights the interplay between a pro-inflammatory cytokine microenvironment and tumor-mediated immune suppression, and addresses the importance of accurately diagnosing these entities for appropriate clinical management.

Morphea and lichen sclerosus et atrophicus (LSA) are two diseases that show considerable clinical and histopathological similarity and have been known to coexist in the same patient. Whether the two conditions are different entities or part of the same spectrum has been a topic of debate. This article describes a very rare and interesting case of concomitant morphea and LSA in a 50-year-old female in the same plaque following intramuscular drug injection in the deltoid region of the right arm. The coexistence of morphea and LSA in the same lesion has rarely been reported, thus compelling us to report this case.
Florid papillomatosis of the nipple: a rare presentation and review of the literature.
Salemis, Nikolaos S
2015-01-01
Florid papillomatosis (FP) of the nipple, or nipple adenoma, is a rare benign proliferative lesion originating from the lactiferous ducts of the nipple. It most commonly affects women in their fourth and fifth decades of life. Clinically, in most cases FP presents with serous or serosanguinous nipple discharge while in many cases an erythematoid or eroded lesion, a nodule or a swelling of the nipple may coexist thus resembling Paget's disease. We describe a case of FP with a very unusual clinical presentation. Diagnostic evaluation and management of the patient are discussed along with a review of the relevant literature. We conclude that FP should be always considered in the differential diagnosis of patients presenting with a rapidly enlarging nipple nodule even in the absence of any skin lesions or nipple discharge. Early diagnosis and prompt treatment are essential. Simple complete excision in order to eliminate the risk of recurrence is the treatment of choice for FP. Although in rare cases a coincidental ipsilateral or contralateral breast cancer has been reported, FP is considered as an entirely benign clinical entity associated with excellent prognosis.
Relatedness-based Multi-Entity Summarization

2017-01-01
Representing world knowledge in a machine processable format is important as entities and their descriptions have fueled tremendous growth in knowledge-rich information processing platforms, services, and systems. Prominent applications of knowledge graphs include search engines (e.g., Google Search and Microsoft Bing), email clients (e.g., Gmail), and intelligent personal assistants (e.g., Google Now, Amazon Echo, and Apple’s Siri). In this paper, we present an approach that can summarize facts about a collection of entities by analyzing their relatedness in preference to summarizing each entity in isolation. Specifically, we generate informative entity summaries by selecting: (i) inter-entity facts that are similar and (ii) intra-entity facts that are important and diverse. We employ a constrained knapsack problem solving approach to efficiently compute entity summaries. We perform both qualitative and quantitative experiments and demonstrate that our approach yields promising results compared to two other stand-alone state-of-the-art entity summarization approaches.

Masked proportional routing is an improved procedure for choosing links between adjacent nodes of a network for the purpose of transporting an entity from a source node ("A") to a destination node ("B"). The entity could be, for example, a physical object to be shipped, in which case the nodes would represent waypoints and the links would represent roads or other paths between waypoints. For another example, the entity could be a message or packet of data to be transmitted from A to B, in which case the nodes could be computer-controlled switching stations and the links could be communication channels between the stations. In yet another example, an entity could represent a workpiece while links and nodes could represent, respectively, manufacturing processes and stages in the progress of the workpiece towards a finished product. More generally, the nodes could represent states of an entity and the links could represent allowed transitions of the entity. The purpose of masked proportional routing and of related prior routing procedures is to schedule transitions of entities from their initial states ("A") to their final states ("B") in such a manner as to minimize a cost or to attain some other measure of optimality or efficiency. Masked proportional routing follows a distributed (in the sense of decentralized) approach to probabilistically or deterministically choosing the links. It was developed to satisfy a need for a routing procedure that 1. Does not always choose the same link(s), even for two instances characterized by identical estimated values of associated cost functions; 2. Enables a graceful transition from one set of links to another set of links as the circumstances of operation of the network change over time; 3. Is preferably amenable to separate optimization of different portions of the network; 4. Is preferably usable in a network in which some of the routing decisions are made by one or more other procedure(s); 5. Preferably does not cause an entity to visit the same node twice; and 6. Preferably can be modified so that separate entities moving from A to B do not arrive out of order.
Factitious Disorder as Repeated Diabetic Ketoacidosis
Oettel, David J.
2011-01-01
Factitious disorder is a challenging entity, both in diagnosis and treatment. The clinical presentation is variable in feigned symptoms and spans virtually all organ systems. The diagnostic criteria are simple, yet making the diagnosis is often complicated and can be delayed by focusing on the urgent or readily observable diagnosis. In this article, the authors present a case of factitious diabetic ketoacidosis resulting from the deliberate withholding of exogenous insulin. This particular case is dissected in order to portray the underlying psychopathology. In doing so, the authors illustrate how a patient with factitious disorder might fulfill unmet, presumably unrealized needs. The authors also discuss the diagnostic criteria and treatment strategies of factitious disorder, both of which are of considerable debate within the psychiatric community. PMID:21468297
Multifocal synchronous ipsilateral Warthin tumors: case report and review of the literature.

We report a case of a 73-year-old woman who presented with an enlarging superficial parotid mass, a concomitant ipsilateral deep-lobe parotid mass, and associated upper jugular lymphadenopathy. The clinical presentation and radiographic imaging were suggestive of malignancy, and the patient was treated with total parotidectomy with upper jugular lymph node sampling. Pathologic examination revealed two distinct masses, one in the superficial lobe and one in the deep lobe of the parotid gland, both consistent with synchronous Warthin tumors. Analysis of the upper jugular lymph nodes was consistent with reactive lymphoid hyperplasia. Although the true incidence of multicentricity in ipsilateral Warthin tumors may be underappreciated and underreported, this entity should remain in the differential diagnosis for unilateral parotid masses.

Parapharyngeal neuroglial heterotopia is a rare entity, and the specific radiographical findings are unclear. We present a case of parapharyngeal neuroglial heterotopia examined with proton magnetic resonance spectroscopy ( 1 H-MRS) and 18 F-fluorodesoxyglucose positron emission tomography ( 18 F-FDG PET). Our neonate patient presented with neck mass and polyhydramnios during gestation. Computed tomography and magnetic resonance imaging demonstrated the morphological characteristics, but failed to establish the diagnosis. 1 H-MRS showed a non-malignant pattern, but 18 F-FDG PET demonstrated high glucose metabolism. Complete resection was achieved and the histopathological diagnosis was neuroglial heterotopia. Assessment of biological activity may be useful for both preoperative diagnosis and postoperative evaluation of residual lesions.

Cat scratch disease (CSD) can present as a systemic disease in 5-10% of cases and lead to various disease entities. A previously healthy 16-month-old boy presented with fever for 7 days without other obvious symptoms. Abdominal computed tomography scan demonstrated enlarged right inguinal lymph nodes and multiple small round hypodensities in the spleen. Despite antibiotic treatment for 1 week, the fever persisted and the intrasplenic lesions progressed. Inguinal lymph node biopsy confirmed CSD by immunohistochemistry staining. The diagnosis of CSD was also supported by a history of contact, imaging and serological findings. The patient recovered after treatment with azithromycin for a total of 5 weeks and, in serial follow-up, the hepatosplenic micro-abscesses resolved after 4th months.

We report the case of a 26-year-old man who presented with small soft nodules with tiny hairs that had been present on his nose since childhood. The nodules were initially diagnosed as melanocytic nevi. However, dermoscopy showed many uniform hair follicles and an interfollicular 'pseudo-pigment network' in the nodules. Histologically, many well-differentiated hair follicles and sebaceous glands were seen in the dermis. Serial sectioning revealed neither central cysts nor a central canal. We therefore diagnosed this case as hair follicle nevus. Dermoscopy is now widely used as a non-invasive, in vivo technique for the diagnosis of pigmented skin lesions. Hair follicle nevus is a very rare disease and this is the first report to demonstrate the manifestation of this clinical entity by dermoscopy.
Rare Abdominal Wall Malformation: Case Report of Umbilical Cord Hernia.
Gliha, Andro; Car, Andrija; Višnjić, Stjepan; Zupancic, Bozidar; Kondza, Karmen; Petracic, Ivan
The umbilical cord hernia is the rarest form of abdominal wall malformations, anatomically completely different from gastroschisis and omphalocele. It occurs due to the permanent physiological evisceration of abdominal organs into umbilical celom and persistence of a patent umbilical ring. The umbilical cord hernia is often mistaken for omphalocele and called "small omphalocele". Here we present a case of a female newborn with umbilical cord hernia treated in our Hospital. After preoperative examinations surgery was done on the second day of life. The abdominal wall was closed without tension. The aim of this article is to present the importance of the proper diagnose of these three entities and to stimulate academic community for the answer, is this umbilical cord hernia or small omphalocele.

Astroblastoma is a rare and controversial glioma with variable clinical behavior. The diagnosis currently rests on histologic findings of a circumscribed glioma with astroblastomatous pseudorosettes and vascular hyalinization. Immunohistochemical studies have suggested different oncogenic drivers, such as BRAF p.V600E, but very few cases have been studied using genome-wide methodologies. Recent genomic profiling identified a subset of CNS embryonal tumors with astroblastoma-like morphology that harbored MN1 gene fusions, termed "CNS high-grade neuroepithelial tumors with MN1 alteration" (CNS-HGNET-MN1). To further characterize the genetic alterations that drive astroblastomas, we performed targeted next-generation sequencing (NGS) of 500 cancer-associated genes in a series of eight cases. We correlated these findings with break-apart fluorescence in situ hybridization (FISH) analysis of the MN1 locus and genome-wide DNA methylation profiling. Four cases showed MN1 alteration by FISH, including two pediatric cases that lacked other pathogenic alterations, and two adult cases that harbored other cancer-associated gene mutations or copy number alterations (eg, CDKN2A/B homozygous deletion, TP53, ATM and TERT promoter mutations). Three of these cases grouped with the CNS-HGNET-MN1 entity by methylation profiling. Two of four MN1 intact cases by FISH showed genetic features of either anaplastic pleomorphic xanthoastrocytoma (BRAF p.V600E mutation, CDKN2A/B homozygous deletion and TERT promoter mutation) or IDH-wildtype glioblastoma (trisomy 7, monosomy 10, CDK4 amplification and TP53, NRAS and TERT promoter mutations) and these cases had an aggressive clinical course. Two clinically indolent cases remained unclassifiable despite multimodal molecular analysis. We conclude that astroblastoma histology is not specific for any entity including CNS-HGNET-MN1, and that additional genetic characterization should be considered for astroblastomas, as a number of these tumors likely contain a methylation profile or genetic alterations that suggest classification as other tumor entities. Our heterogeneous molecular findings help to explain the clinical unpredictability of astroblastoma. © 2017 International Society of Neuropathology.

Gastric adenomyomas are extremely uncommon benign tumors in children. On histologic examination, these tumors have an epithelial component similar to pancreatic ducts. We present a case of a pyloric adenomyoma that clinically simulated hypertrophic pyloric stenosis in a newborn girl. Imaging tests, fundamentally magnetic resonance imaging, were very important in the characterization and diagnosis of this entity. Copyright © 2016 SERAM. Published by Elsevier España, S.L.U.

Gastric perforation (GP) in neonates is a rare entity with high mortality. Although the etiology is not completely understood, it mostly occurs in premature neonates on assisted ventilation. Combination of duodenal atresia and gastric perforation is very rare. We present a case duodenal atresia who developed gastric perforation after operetion for duodenal atresia. Analysis of the patient medical record and histology report did not reveal the etiology of the perforation. PMID:27896170

Stuttering priapism is a clinical phenomenon that occurs commonly in certain patient populations, including sickle cell anemia and other hematologic dyscrasias. Although the mechanism is still not completely understood, treatment is focused on prevention of recurrence in the outpatient setting, and immediate detumescence and minimizing corporal fibrosis in the acute setting. We present a case of stuttering priapism in a 44 year-old male with hereditary spherocytosis and discuss the pathophysiology and clinical management of this entity.

Sialolipoma is a rare neoplasm of salivary glands, described as a distinct entity by Nagao et al. in 2001. Thirty-six cases of sialolipoma in minor and major salivary glands have been reported thus far in addition to the two new cases of sialolipoma arising in the major salivary glands in this study. Thirty-six cases of sialolipoma published in English language reports were analyzed considering gender, age, location, size, duration of symptoms, treatment mode, follow-up, and histologic findings. Congenital sialolipomas were considered in this study. The first case occurred in a 45-year-old female and presented as a localized swelling in right parotid area. The second case occurred in an 18-year-old female as a swelling in the left parotid region. On histopathological examination, these lesions were diagnosed as sialolipoma. PMID:23878570

One of the central incentives for linked data implementations is the opportunity to leverage the rich logic inherent in structured data. The logic embedded in semantic models can strengthen capabilities for data discovery and data validation when pairing entities from distinct, contextually-related datasets. The creation of links between the two datasets broadens data discovery by using the semantic logic to help machines compare similar entities and properties that exist on different levels of granularity. This semantic capability enables appropriate entity pairing without making inaccurate assertions as to the nature of the relationship. Entity pairing also provides a context to accurately validate the correctness of an entity's property values - an exercise highly valued by data management practices who seek to ensure the quality and correctness of their data. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) semantically models metadata surrounding oceanographic researchcruises, but other sources outside of BCO-DMO exist that also model metadata about these same cruises. For BCO-DMO, the process of successfully pairing its entities to these sources begins by selecting sources that are decidedly trustworthy and authoritative for the modeled concepts. In this case, the Rolling Deck to Repository (R2R) program has a well-respected reputation among the oceanographic research community, presents a data context that is uniquely different and valuable, and semantically models its cruise metadata. Where BCO-DMO exposes the processed, analyzed data products generated by researchers, R2R exposes the raw shipboard data that was collected on the same research cruises. Interlinking these cruise entities expands data discovery capabilities but also allows for validating the contextual correctness of both BCO-DMO's and R2R's cruise metadata. Assessing the potential for a link between two datasets for a similar entity consists of aligning like properties and deciding on the appropriate semantic markup to describe the link. This highlights the desire for research organizations like BCO-DMO and R2R to ensure the complete accuracy of their exposed metadata, as it directly reflects on their reputations as successful and trustworthy source of research data. Therefore, data validation reaches beyond simple syntax of property values into contextual correctness. As a human process, this is a time-intensive task that does not scale well for finite human and funding resources. Therefore, to assess contextual correctness across datasets at different levels of granularity, BCO-DMO is developing a system that employs semantic technologies to aid the human process by organizing potential links and calculating a confidence coefficient as to the correctness of the potential pairing based on the distance between certain entity property values. The system allows humans to quickly scan potential links and their confidence coefficients for asserting persistence and correcting and investigating misaligned entity property values.
An approach to define semantics for BPM systems interoperability

This article proposes defining semantics for Business Process Management systems interoperability through the ontology of Electronic Business Documents (EBD) used to interchange the information required to perform cross-organizational processes. The semantic model generated allows aligning enterprise's business processes to support cross-organizational processes by matching the business ontology of each business partner with the EBD ontology. The result is a flexible software architecture that allows dynamically defining cross-organizational business processes by reusing the EBD ontology. For developing the semantic model, a method is presented, which is based on a strategy for discovering entity features whose interpretation depends on the context, and representing them for enriching the ontology. The proposed method complements ontology learning techniques that can not infer semantic features not represented in data sources. In order to improve the representation of these entity features, the method proposes using widely accepted ontologies, for representing time entities and relations, physical quantities, measurement units, official country names, and currencies and funds, among others. When the ontologies reuse is not possible, the method proposes identifying whether that feature is simple or complex, and defines a strategy to be followed. An empirical validation of the approach has been performed through a case study.

Hyalinizing clear cell carcinoma (HCCC) is a rare low-grade tumour of salivary glands that was first described as a distinct entity in 1994 by Milchgrub et al. EWSR1-ATF1 fusion was found to be specific for this tumour. The majority of the reported cases of HCCC arise from minor salivary glands within the oral cavity. Primary HCCC of the paranasal sinus is extremely uncommon. To our knowledge, only three cases have been reported in the English literature. Herein, we present a case of HCCC of the posterior ethmoid/maxillary sinus. A 63-year-old lady who presented with a long history of epistaxis. CT scan revealed a destructive mass in the left ethmoid/posterior maxillary sinus extending to the nasal cavity. Surgical excision was done and microscopic evaluation showed a tumour composed mainly of nests of clear epithelial cells separated by fibrocellular and hyalinized septa with extensive bone destruction. The tumour cells expressed CK5/6, EMA and p63 immunohistochemically but were negative for S100 protein, PAX-8, RCC and CK7. Sinonasal renal cell-like adenocarcinomas, myoepithelial carcinoma and metastatic renal cell carcinoma were excluded by radiological and immunohistochemical studies. Fluorescence in situ hybridization analysis revealed an EWSR1 gene rearrangement. Postoperative radiation was administrated and the patient did not show recurrence or distant metastasis 4 months after the surgery. Head and neck region have many tumours that demonstrate clear cell changes on histology. Thus, the differential diagnosis for HCCC is wide. Awareness of this rare entity and the possibility of it is arising in unusual location is necessary. EWSR1-AFT1 fusion, a consistent finding in HCCC, can be used to confirm the diagnosis.

Purpose: To present various forms of uveitis and/or retinal vasculitis attributed to Bartonella infection and review the impact of this microorganism in patients with uveitis. Methods: Retrospective case series study. Review of clinical records of patients diagnosed with Bartonella henselae and Bartonella quintana intraocular inflammation from 2001 to 2010 in the Ocular Inflammation Department of the University Eye Clinic, Ioannina, Greece. Presentation of epidemiological and clinical data concerning Bartonella infection was provided by the international literature. Results: Eight patients with the diagnosis of Bartonella henselae and two patients with B. quintana intraocular inflammation were identified. Since four patients experienced bilateral involvement, the affected eyes totaled 14. The mean age was 36.6 years (range 12–62). Uveitic clinical entities that we found included intermediate uveitis in seven eyes (50%), vitritis in two eyes (14.2%), neuroretinitis in one eye (7.1%), focal retinochoroiditis in one eye (7.1%), branch retinal vein occlusion (BRVO) due to vasculitis in one eye (7.1%), disc edema with peripapillary serous retinal detachment in one eye (7.1%), and iridocyclitis in one eye (7.1%). Most of the patients (70%) did not experience systemic symptoms preceding the intraocular inflammation. Antimicrobial treatment was efficient in all cases with the exception of the case with neuroretinitis complicated by anterior ischemic optic neuropathy and tubulointerstitial nephritis. Conclusion: Intraocular involvement caused not only by B. henselae but also by B. quintana is being diagnosed with increasing frequency. A high index of suspicion is needed because the spectrum of Bartonella intraocular inflammation is very large. In our study the most common clinical entity was intermediate uveitis. PMID:21750616

A case of florid reactive periostitis ossificans (RPO) arising in a long bone is presented. This is a rare bone proliferation with a pronounced periosteal reaction. Less than 100 cases have been described in the literature with far fewer outside the bones of the hand, feet, fingers, and toes. Although the etiology is unknown, a relationship to preceding trauma is suggested. The imaging and histologic features show an overlap with other bone lesions including bizarre parosteal osteochondromatous proliferation, subungual exostosis, and malignant surface tumors of bone and cartilage which include, periosteal and parosteal osteosarcoma. It is important to recognize the clinical presentation and diagnostic features of RPO as a benign entity so that it is not mistaken for a more aggressive neoplasm. We present a case of a right distal humeral lesion that on histopathological review revealed florid RPO. This diagnosis was not suspected on imaging studies, but was made on open biopsy of the mass. The patient remains disease free, years postoperatively. In addition to presenting this unique case report, we review the pertinent literature, and offer a differential diagnosis and treatment strategy for its management. PMID:26301184
Prostate carcinoma metastatic to the skin as an extrammamary Paget’s disease
2012-01-01
Aim The current paper describes a case of prostatic adenocarcinoma metastatic to the skin presenting as an extrammamary Paget's disease, a very rare and poorly characterised morphological entity. We report a case of prostatic carcinoma metastatic to skin showing a pattern of extramammary Paget's disease which has not been clearly illustrated in the literature Case presentation: A 63 year-old man with prostatic adenocarcinoma developed cutaneous metastases after 16 years. The inguinal metastases were sessile and 'keratotic.' The tumour displayed solid, glandular areas as well as a polypoid region suggestive of extramammary Paget's disease were identified. Discussion and conclusions We review the diagnostic criteria that have led to the correct histopathological diagnosis in this case. A differential diagnosis of the pagetoid spread in the skin and various forms of cutaneous metastases determined by a prostatic adenocarcinoma as well as the role of immunohistochemistry in establishing the prostatic origin are presented in the context of this case. Although, morphologically the cells presented in the skin deposits were not characteristic for adenocarcinoma of prostate, immunohistochemistry for PSA and PSAP suggested a prostatic origin.

Heritable Thoracic Aortic Disorders (H-TAD) may present clinically as part of a syndromic entity or as an isolated (nonsyndromic) manifestation. About one dozen genes are now available for clinical molecular testing. Targeted single gene testing is hampered by significant clinical overlap between syndromic H-TAD entities and the absence of discriminating features in isolated cases. Therefore panel testing of multiple genes has now emerged as the preferred approach. So far, no data on mutation detection rate with this technique have been reported. We performed Next Generation Sequencing (NGS) based screening of the seven currently most prevalent H-TAD-associated genes (FBN1, TGFBR1/2, TGFB2, SMAD3, ACTA2 and COL3A1) on 264 samples from unrelated probands referred for H-TAD and related entities. Patients fulfilling the criteria for Marfan syndrome (MFS) were only included if targeted FBN1 sequencing and MLPA analysis were negative. A mutation was identified in 34 patients (13%): 12 FBN1, one TGFBR1, two TGFBR2, three TGFB2, nine SMAD3, four ACTA2 and three COL3A1 mutations. We found mutations in FBN1 (N = 3), TGFBR2 (N = 1) and COL3A1 (N = 2) in patients without characteristic clinical features of syndromal H-TAD. Six TAD patients harboring a mutation in SMAD3 and one TAD patient with a TGFB2 mutation fulfilled the diagnostic criteria for MFS. NGS based H-TAD panel testing efficiently reveals a mutation in 13% of patients. Our observations emphasize the clinical overlap between patients harboring mutations in syndromic and nonsyndromic H-TAD related genes as well as within syndromic H-TAD entities, justifying a widespread application of this technique.

Osteolipoma is a rare variant of the ubiquitous lipoma. Published literature appears in the form of isolated case reports affecting soft tissue structures in the head, neck and rarely affecting the spine. We present a unique instance of an intraspinal osteolipoma in the cervical spine, without evidence of accompanying spinal dysraphism and an atypical clinical presentation of isolated dorsal column dysfunction. We describe the clinical presentation, operative procedure and post-operative outcomes with histopathological findings of this rare entity. A 61-year-old male presented with impaired dorsal column sensation due to an intraspinal extradural ossifying lesion in the cervical spinal canal. The patient underwent excision of the lesion with complete resolution of symptoms. Ossifying lesion in the spinal canal may be frequent finding on radiological imaging but presence of possible adipose tissue in the lesion should raise suspicion of rare clinical scenario of an osteolipoma.
Phrenic Nerve Palsy as Initial Presentation of Large Retrosternal Goitre.
Hakeem, Arsheed Hussain; Hakeem, Imtiyaz Hussain; Wani, Fozia Jeelani
2016-12-01
Unilateral phrenic nerve palsy as initial presentation of the retrosternal goitre is extremely rare event. This is a case report of a 57-year-old woman with history of cough and breathlessness of 3 months duration, unaware of the thyroid mass. She had large cervico-mediastinal goiter and chest radiograph revealed raised left sided hemidiaphragm. Chest CT scan did not reveal any lung parenchymal or mediastinal pathology. The patient underwent a total thyroidectomy through a cervical approach. The final pathology was in favor of multinodular goitre. Even after 1 year of follow up, phrenic nerve palsy did not improve indicating permanent damage. Phrenic nerve palsy as initial presentation of the retrosternal goitre is unusual event. This case is reported not only because of the rare nature of presentation, but also to make clinicians aware of the entity so that early intervention may prevent attendant morbidity.
Hepatobiliary fascioliasis in non-endemic zones: a surprise diagnosis.
Jha, Ashish Kumar; Goenka, Mahesh Kumar; Goenka, Usha; Chakrabarti, Amrita
2013-03-01
Fascioliasis is a zoonotic infection caused by Fasciola hepatica. Because of population migration and international food trade, human fascioliasis is being an increasingly recognised entity in nonendemic zones. In most parts of Asia, hepatobiliary fascioliasis is sporadic. Human hepatobiliary infection by this trematode has two distinct phases: an acute hepatic phase and a chronic biliary phase. Hepatobiliary infection is mostly associated with intense peripheral eosinophilia. In addition to classically defined hepatic phase and biliary phase fascioliasis, some cases may have an overlap of these two phases. Chronic liver abscess formation is a rare presentation. We describe a surprise case of hepatobiliary fascioliasis who presented to us with liver abscess without intense peripheral eosinophilia, a rare presentation of human fascioliasis especially in non-endemic zones.

3M syndrome: a report of four cases in two families.
Güven, Ayla; Cebeci, Ayşe Nurcan
2011-01-01
3M syndrome is a rare entity characterized by severe growth retardation, dysmorphic features and skeletal changes as its major components. It is differentiated from other types of dwarfism by its clinical features and by the typical slender long bones and foreshortened vertebral bodies that can be visualized radiographically. 3M syndrome has an autosomal recessive mode of inheritance. An early diagnosis is important for genetic counseling. In this report, we present four children (3 males, 1 female) from two families who were aged between 4(11/12) and 10(11/12) years and had clinical findings of 3M syndrome. One of these patients had received growth hormone (GH) treatment which was discontinued due to an inadequate height gain. Physicians should be aware of this entity in the differential diagnosis of children with severe short stature and mild skeletal changes.

Intradural Extramedullary Capillary Hemangioma in the Upper Cervical Spine: First Report.
Bouali, Sofiene; Maatar, Nidhal; Bouhoula, Asma; Abderrahmen, Khansa; Kallel, Jalel; Jemel, Hafedh
2016-08-01
The occurrence of intradural extramedullary capillary hemangiomas is exceedingly rare. To date, only 39 cases of intradural extramedullary capillary hemangiomas have been reported in the English literature, and all of these cases have been described at the lumbar and thoracic spinal levels. To our knowledge, this report is the first case of capillary hemangiomas of the cervical spine in the literature. In general, this entity is misdiagnosed preoperatively as a neoplasm. A 29-year-old man presented with neck pain and progressive gait disturbance, and was diagnosed with an intradural extramedullary capillary hemangioma in the cervical region. Although rare, our case demonstrates that capillary hemangioma should be considered in the differential diagnosis of intradural extramedullary tumor of the cervical spine.

The presence of air inside intracranial cavity is a rare entity known as pneumocephalus and in most cases doesńt present any clinical repercussion except in case of elevated intracranial pressure that can lead to a decreasing level of consciousness, coma and even death. We present a rare case of a young male, without medical precedents of interest, hospitalized in an intensive care unit for vigilance after a traffic accident with asymptomatic crane encephalic trauma and cranial computerized tomography without meaningful findings. During the intensive care unit stay positive pressure is applied in airway with non-invasive mechanical ventilation that produces air entrance in cranial cavity (pneumocephalus) causing neurological deterioration and necessity of urgent surgery.

Patients presenting with a penetrating missile lodged in the pelvis are at risk for having a urinary tract injury. Once in the bladder, the missile can become impacted in the urethra, causing retention that requires extraction. Rarely, the missile can be expulsed spontaneously through the urethra. To describe the world literature regarding undetected penetrating bladder injuries presenting as spontaneously voided bullets and to contribute an additional case to the literature. We present a case report of a 37-year-old man who sustained a gunshot wound to the right buttock, with an undetected urinary system injury and subsequent spontaneous voiding of a bullet. There have been <10 cases reported in the literature of spontaneously expulsed bullets from the urethra, all of which were undetected injuries on initial presentation. Physicians should be aware of the potential for undetected urinary tract injuries in patients with penetrating missiles to the pelvis and understand the appropriate evaluation and management strategies for these injuries.

Differential diagnosis of geniculate ganglion tumours includes chiefly schwannomas, haemangiomas and meningiomas. We report the case of a patient whose clinical and imaging findings mimicked the presentation of a facial nerve schwannoma.Pathological studies revealed a lesion with nerve bundles unstructured by intense collagenisation. Consequently, it was called fibrous connective tissue lesion of the facial nerve. Copyright © 2011 Elsevier España, S.L. All rights reserved.

Aortic aneurysms in childhood are rare disease entities and are usually seen in patients with genetic connective tissue disorders such as Marfans, Ehler-Danlos, and Loeys-Dietz syndrome (LDS). Patients affected with LDS present early in life and have a rapid disease progression. We report a case of repair of an ascending and aortic arch aneurysm in an infant with Loeys-Dietz syndrome. © 2018 Wiley Periodicals, Inc.
Collagenous spherulosis presenting as a mass of the breast.
Jan, Yee-Jee; Li, Mu-Chun; Ho, William L
2002-10-01
Collagenous spherulosis (CS) is a rare benign lesion which typically presents as an incidental microscopic finding accompanying other breast lesions. Pathologists who are not familiar with this entity occasionally misdiagnose CS as adenoid cystic carcinoma (ACC), cribriform ductal carcinoma in situ (C-DCIS), or atypical intraductal hyperplasia (AIH), especially when it presents as a mass. It is of utmost importance to differentiate benign CS from its malignant mimics in order to avoid unnecessary treatment. We report an unusual case of CS manifested as a mass in the right breast of a 45-year-old female and discuss the problems of differential diagnosis and histogenesis.

Bilateral venous thrombosis due to underlying malignancy is a rare entity. It is worthy to search for malignancy in patients of bilateral venous gangrene. Our patient presented with severe bilateral leg pain as a result of venous gangrene. There was associated left sided massive pleural effusion with scalp nodule. Fine needle aspiration cytology of scalp nodule revealed metastatic squamous cell carcinoma and fiber optic bronchoscopy guided biopsy from growth at left upper lobe bronchus confirmed the case as squamous cell carcinoma lung. It was rare for squamous cell carcinoma lung to present as bilateral venous gangrene with anticardiolipin antibody negative. PMID:24455526

Background POLG1 mutations have been associated with MELAS-like phenotypes. However given several clinical differences it is unknown whether POLG1 mutations are possible causes of MELAS or give raise to a distinct clinical and genetic entity, named POLG1-associated encephalopathy. Case presentation We describe a 74 years old man carrying POLG1 mutations presenting with strokes, myopathy and ragged red fibers with some atypical aspects for MELAS such as late onset, lack of cerebral calcification and presence of frontal and occipital MRI lesions better consistent with the POLG associated-encephalopathy spectrum. Conclusion The lack of available data hampers a definite diagnosis in our patient as well as makes it difficult to compare MELAS, which is a clearly defined clinical syndrome, with POLG1-associated encephalopathy, which is so far a purely molecularly defined syndrome with a quite heterogeneous clinical picture. However, the present report contributes to expand the phenotypic spectrum of POLG1 mutations underlining the importance of searching POLG1 mutations in patients with mitochondrial signs and MELAS like phenotypes but negative for common mtDNA mutations.

Embedded object concept with a telepresence robot system
NASA Astrophysics Data System (ADS)
Vallius, Tero; Röning, Juha
2005-10-01
This paper presents the Embedded Object Concept (EOC) and a telepresence robot system which is a test case for the EOC. The EOC utilizes common object-oriented methods used in software by applying them to combined Lego-like software-hardware entities. These entities represent objects in object-oriented design methods, and they are the building blocks of embedded systems. The goal of the EOC is to make the designing of embedded systems faster and easier. This concept enables people without comprehensive knowledge in electronics design to create new embedded systems, and for experts it shortens the design time of new embedded systems. We present the current status of the EOC, including two generations of embedded objects named Atomi objects. The first generation of the Atomi objects has been tested with different applications, and found to be functional, but not optimal. The second generation aims to correct the issues found with the first generation, and it is being tested in a relatively complex test case. The test case is a telepresence robot consisting of a two wheeled human height robot and its computer counter part. The robot has been constructed using incremental device development, which is made possible by the architecture of the EOC. The robot contains video and audio exchange capability, and a controlling and balancing system for driving with two wheels. The robot is built in two versions, the first consisting of a PDA device and Atomi objects, and the second consisting of only Atomi objects. The robot is currently incomplete, but for the most part it has been successfully tested.

BACKGROUND--Collagenous colitis and lymphocytic colitis present with a similar clinical picture. Whether these conditions are separate entities or whether they represent different pathological stages of the same condition is an unresolved issue. PATIENT--This is a case of collagenous colitis following a fulminant course in which a colectomy was necessary. In the operative specimen the thickened collagen plate, which had been present only two weeks preoperatively had been lost and the pathology was of a lymphocytic colitis. Six months postoperatively this patient developed a CREST syndrome and primary biliary cirrhosis. CONCLUSIONS--This case shows the lability of the collagen plate and the common ground between collagenous and lymphocytic colitis, and presents evidence that these two conditions are different manifestations of the same disease. It also describes for the first time an association between collagenous colitis and CREST syndrome and primary biliary cirrhosis. Images Figure 1 Figure 3 Figure 4 Figure 5 PMID:8707130
Cutaneous plasmacytosis: A rare entity with unique presentation.
Dhar, Subhra; Liani, Lalthleng; Patole, Kamlakar; Dhar, Sandipan
2017-01-01
Primary cutaneous plasmacytosis is a rare cutaneous disorder with extensive cutaneous plaques/papules mainly on the trunk and face. Cases have mostly been documented from Japan. We present here a rare case of cutaneous plasmacytosis from India of Mongolian descent. This 50-year-old female from Mizoram had extensive maculo-papular violaceous plaques distributed on the face, axillae, trunk and lower extremities. Initial and repeat skin biopsy revealed dense perivascular and periadnexal mature plasma cells. She also had lymphadenopathy. Serum protein electrophoresis did not reveal any M band and the Bence Jones protein was negative in urine. The patient had multiple superficial lymph nodes and a biopsy from the cervical lymph node showed effacement of normal nodal architecture by sheets of plasma cells. Immuno histochemistry was done from both skin and lymph node biopsies. The kappa and lambda tight chains were not restricted; there by proving the polyclonal nature of the plasma cells. The novelty of the case lies in its classical clinical presentation with histopathological documentation.

Mutations in the gene encoding parkin (PARK2) are the most common cause of autosomal recessive juvenile-onset and young-onset parkinsonism. The few available detailed neuropathologic reports suggest that homozygous and compound heterozygous parkin mutations are characterized by severe substantia nigra pars compacta neuronal loss. To investigate whether parkin-linked parkinsonism is a different clinicopathologic entity to Parkinson disease (PD). We describe the clinical, genetic, and neuropathologic findings of 5 unrelated cases of parkin disease and compare them with 5 pathologically confirmed PD cases and 4 control subjects. The PD control cases and normal control subjects were matched first for age at death then disease duration (PD only) for comparison. Presenting signs in the parkin disease cases were hand or leg tremor often combined with dystonia. Mean age at onset was 34 years; all cases were compound heterozygous for mutations of parkin. Freezing of gait, postural deformity, and motor fluctuations were common late features. No patients had any evidence of cognitive impairment or dementia. Neuronal counts in the substantia nigra pars compacta revealed that neuronal loss in the parkin cases was as severe as that seen in PD, but relative preservation of the dorsal tier was seen in comparison with PD (P = .04). Mild neuronal loss was identified in the locus coeruleus and dorsal motor nucleus of the vagus, but not in the nucleus basalis of Meynert, raphe nucleus, or other brain regions. Sparse Lewy bodies were identified in 2 cases (brainstem and cortex). These findings support the notion that parkin disease is characterized by a more restricted morphologic abnormality than is found in PD, with predominantly ventral nigral degeneration and absent or rare Lewy bodies.

We report a series of 7 unusual and morphologically distinct cervical or upper vaginal lesions in women aged 41 to 70 years. The lesions involved the cervix in 3 cases, the upper vagina in 2, the cervix and vagina in 1, and in 1 case the site of origin could not be determined. The lesions had a consistent morphologic appearance with a surface "plaque-like" or "stuck-on" configuration apparent in those cases where surrounding normal tissues were present. Broad coalescing solid sheets and interconnecting trabeculae of cytologically bland cells with a rather "basaloid" appearance emanated from the surface and there were scattered squamous eddies. Other features included peripheral palisading and a stroma containing hyalinized basement membrane-like material. Immunohistochemically, the lesions were diffusely positive with p63, CK5/6, and 34βE12 and focally positive with CK7, but largely negative with CK20, EMA, CEA, and BerEP4. p16 was negative or exhibited nonblock-type immunoreactivity and GATA3 was negative or weakly positive. Molecular testing detected human papillomavirus type 42 in 3 of 7 cases, with no virus detected in the remaining 4 cases. Rarely, similar cases have been reported previously as inverted transitional papilloma of the cervix or vagina, but based on the morphology and immunophenotype we do not feel these represent transitional lesions. We suggest the term seborrheic keratosis-like lesions to designate this new and rare entity, which may be associated with low-risk human papillomavirus infection. Limited follow-up in a small number of cases suggests that these lesions follow a benign clinical course.

To report a rare case of extranodal NK/T cell lymphoma (NKTL) and to compare its features with those cases previously reported. Case report, observational and literature review. Complete ophthalmologic examinations followed by excisional biopsy, histopathologic examination and therapy with radiation and chemotherapy. Evaluation of clinical presenting features and histopathologic diagnosis along with patient outcome. A 22 year old female presented as a referral with right orbital swelling, decreased vision and eye pain for 5 weeks. Subsequent orbital CT and multiple biopsies resulted in a diagnosis of extranodal natural killer (NK)/T cell lymphoma (NKTL). Despite continued chemotherapy and orbital radiation the patient expired within 3 months of diagnosis. To our knowledge, only 8 cases of orbital involvement without nasal mucosal involvement are reported in the literature, the majority in patients of male gender around the fifth decade. Here we present an atypical and aggressive case of extranodal NK/T cell lymphoma presenting in a 22 year old Caucasian female as orbital swelling without evidence of nasal mucosal involvement. It is important to distinguish NKTL from the more common benign lymphoproliferative lesions of the orbital adnexa as prognosis of these two clinical entities varies and timely diagnosis is key. The present case demonstrates that extranodal NKTL can occur in the orbit without evidence of the more common nasal mucosal presentations and should be included in the differential diagnosis of ocular adnexal lesions suspicious for a lymphoproliferative disorder and/or an inflammatory process.

The incidence of gastrointestinal metastases from lung cancer is higher than previously thought as they have been reported in 2-14% of the cases in autopsy studies. However, clinically significant metastases are rare. Small bowel perforation secondary to metastatic non-small cell lung cancer is a very rare clinical entity. The aim of this study is to describe a case of ileal perforation in a patient with intestinal metastases of a non-small cell lung cancer, along with a review of the literature. A 57-year-old male with a history of non-small cell lung cancer was referred to our emergency department with signs and symptoms of acute surgical abdomen. A computed tomography scan demonstrated dilated small bowel loops, liver deposits, and signs of perforation of an intra-abdominal hollow viscus. Emergency exploratory laparotomy revealed diffuse purulent peritonitis and a perforated ileal tumor. A segmental small bowel resection and primary anastomosis were performed. Histological and immunohistochemical findings were consistent with a metastatic non-small cell lung carcinoma. Additional evaluation revealed widespread metastatic disease. Unfortunately, despite adjuvant treatment, the patient died of progressive disease 2 months after surgery. Small bowel perforation due to metastatic non-small cell lung cancer is a very rare clinical entity. The possibility of small bowel metastases should be kept in mind in patients with lung cancer presenting with an acute abdomen. Intestinal perforation occurs in advanced stages and is usually a sign of widespread disease. Aggressive surgery can provide effective palliation and may improve short-term survival. The prognosis is however dismal.
Risk Modeling of Interdependent Complex Systems of Systems: Theory and Practice.
Haimes, Yacov Y
2018-01-01
The emergence of the complexity characterizing our systems of systems (SoS) requires a reevaluation of the way we model, assess, manage, communicate, and analyze the risk thereto. Current models for risk analysis of emergent complex SoS are insufficient because too often they rely on the same risk functions and models used for single systems. These models commonly fail to incorporate the complexity derived from the networks of interdependencies and interconnectedness (I-I) characterizing SoS. There is a need to reevaluate currently practiced risk analysis to respond to this reality by examining, and thus comprehending, what makes emergent SoS complex. The key to evaluating the risk to SoS lies in understanding the genesis of characterizing I-I of systems manifested through shared states and other essential entities within and among the systems that constitute SoS. The term "essential entities" includes shared decisions, resources, functions, policies, decisionmakers, stakeholders, organizational setups, and others. This undertaking can be accomplished by building on state-space theory, which is fundamental to systems engineering and process control. This article presents a theoretical and analytical framework for modeling the risk to SoS with two case studies performed with the MITRE Corporation and demonstrates the pivotal contributions made by shared states and other essential entities to modeling and analysis of the risk to complex SoS. A third case study highlights the multifarious representations of SoS, which require harmonizing the risk analysis process currently applied to single systems when applied to complex SoS. © 2017 Society for Risk Analysis.
Classical and unusual imaging appearances of melorheostosis.
Suresh, S; Muthukumar, T; Saifuddin, A
2010-08-01
This comprehensive review will discuss the classical and unusual radiological features of melorheostosis, which is an uncommon, non-hereditary, benign, sclerosing mesodermal disease with an incidence of 0.9 cases per million. The presentation of melorheostosis in the appendicular skeleton (more commonly involved) and in the axial skeleton (very few documented case reports) will be discussed. The aim of the review is to illustrate the associations and rare, but recognized, complications of the disorder. The role of cross-sectional imaging in the form of magnetic resonance imaging (MRI) and computed tomography (CT) in revealing the spectrum of disease manifestation and differentiation from other disease entities and malignancy will be explored.

Lymphoblastic lymphoma (LBL), seen primarily in children or young adults, is a malignant neoplasia that originates from B or T lymphocyte precursors and rarely occurs in the oral cavity. In this localization, neither the clinical features nor the radiologic appearances are pathognomic and can pose significant diagnostic problems. Histopathologically, it presents as a round blue cell tumor. An early and accurate diagnosis of this entity is very important due to its high cure rate. We report a case of B-cell LBL involving oral cavity in a 10-year-old child. The purpose of this report is to explore the diagnostic workup. PMID:27194876
Mask face: bilateral simultaneous facial palsy in an 11-year-old boy.

Bilateral facial paralysis is an uncommon clinical entity especially in the pediatric age group and occurs frequently as a manifestation of systemic disease. The most important causes are trauma, infectious diseases, neurological diseases, metabolic, neoplastic, autoimmune diseases and idiopathic disease (Bell's palsy). We report a case of an 11-year-old boy presenting with bilateral simultaneous peripheral facial paralysis. All possible infectious causes were excluded and the patient was diagnosed as having Bell's palsy (idiopathic). The most important approach in these cases is to rule out a life-threatening disease. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

The treatment of head and neck cancer with radiotherapy and radical neck dissection has many recognized complications. Radiotherapy in therapeutic doses can produce devascularization and weakening of bone. Radical neck dissection results in altered mechanics of the shoulder girdle and a disruption of normally balanced forces acting on the clavicle. An unusual case of clavicle fracture which is considered to have resulted from an interaction of the effects of these therapies is discussed. An approach for recognizing and distinguishing this entity by its time course, and radiographic and nuclide bone scan appearance is presented.

Missile embolism is a clinical entity in which a projectile object enters a blood vessel and is carried to a distant part of the body. We present a case of the discovery of an iliac vein to right ventricle missile embolus in a young man, with successful extraction through a right atriotomy. We provide a historical overview of the literature concerning missile embolism, and we argue that whereas acute embolized projectiles should be removed in almost all cases, it may be reasonable to simply observe an asymptomatic chronic missile embolus.

Hematological malignancies (HM) are highly amenable targets for immunotherapeutic intervention and may be effectively treated by antigen-specific T-cell based treatment. Recent studies demonstrate that physiologically occurring anti-cancer T-cell responses in certain HM entities target broadly presented non-mutated epitopes. HLA ligands are thus implied as prime targets for broadly applicable and antigen-specific off-the-shelf compounds. With the aim of assessing the presence of common targets shared among different HM which may enable addressing a larger patient collective we conducted a meta-analysis of 83 mass spectrometry-based HLA peptidome datasets (comprising 40,361 unique peptide identifications) across four major HM (19 AML, 16 CML, 35 CLL, and 13 MM/MCL samples) and investigated similarities and differences within the HLA presented antigenic landscape. We found the cancer HLA peptidome datasets to cluster specifically along entity and lineage lines, suggesting that the immunopeptidome directly reflects the differences in the underlying (tumor-)biology. In line with these findings, we only detected a small set of entity-spanning antigens, which were predominantly characterized by low presentation frequencies within the different patient cohorts. These findings suggest that design of T-cell immunotherapies for the treatment of HM should ideally be conducted in an entity-specific fashion. PMID:28159928
Tuberculous Otitis Media Leading to Sequentialib Bilateral Facial Nerve Paralysis
Gupta, Nitin; Dass, Arjun; Goel, Neha; Tiwari, Sandeep
2015-01-01
Introduction: Tuberculous otitis media (TOM) is an uncommon, insidious, and frequently misdiagnosed form of tuberculosis (TB). In particular, TOM is usually secondary to direct transmission from adjacent organs, while the primary form has been rarely reported. The main aim of treatment is to start the patient on an antitubercular regime and early surgical intervention to decompress the facial nerve if involved. Case Report: The case report of a twenty year-old male with bilateral tuberculous otitis media, who presented himself with fever followed by sequential bilateral facial nerve paralysis, bilateral profound hearing loss, and abdominal tuberculosis leading to intestinal perforation, is presented. To the best available knowledge and after researching literature, no such case depicting the extensive otological complications of tuberculosis has been reported till date. Conclusion: Tuberculosis of the ear is a rare entity and in most cases the clinical features resemble that of chronic otitis media. The diagnosis is often delayed due to varied clinical presentations and this can lead to irreversible complications. Early diagnosis is essential for prompt administration of antitubercular therapy and to prevent complications. PMID:26082906

Carney triad is a very rare syndrome characterized by the synchronous or metachronous occurrence of gastrointestinal stromal tumors, pulmonary chondroma, and extra-adrenal paraganglioma. We present the case of a 36-year-old woman with complete Carney triad who underwent a Ga-DOTA-TATE PET/CT scan for restaging of metastasizing extra-adrenal paraganglioma and for evaluation of targeted radionuclide therapy potential. On the Ga-DOTA-TATE PET scan, increased tracer accumulation was observed in paraganglioma metastases. This case highlights the usefulness of Ga-DOTA-TATE PET/CT for restaging of metastasizing paraganglioma in Carney triad and the option of targeted radionuclide therapy in this entity.

Background Fusobacterium nucleatum is a strict anaerobic microorganism that causes disease entities such as periodontal and soft tissue abscesses, pulmonary and intraabdominal infections and very rarely intracerebral infections. Case presentation Here, we report the rare case of a previously healthy 25-year-old German man with a cerebellar abscess caused by Fusobacterium nucleatum that resulted in rapid brain death. Toxicological screening showed positivity for amphetamines and cannabis. The diagnosis was obtained by polymerase chain reaction amplification of bacterial deoxyribonucleic acid in cerebrospinal fluid. Conclusions In drug users clinicians should think about rare causes of brain abscesses/meningitis. Early diagnosis is necessary and justifies the use of molecular techniques. PMID:24915846
Gingival leiomyomatous hamartoma of the maxilla: a rare entity
Raghunath, Vandana; Manjunatha, Bhari Sharanesha; Al-Thobaiti, Yasser
2016-01-01
Hamartoma is a tumour-like malformation appearing as a focal overgrowth of normal cells. Leiomyomatous hamartomas (LHs) are rare in the oral cavity and commonly seen in the Japanese and less than 40 cases have been reported in the Japanese and English literature. The clinical differential diagnoses are irritational (traumatic) fibroma and congenital epulis. It has to be differentiated histopathologically from its neoplastic counterparts and mesenchymomas. Hence, we report such a case of LHs, which presented as a sessile gingival growth occurring in the midline in a 15-year-old girl. The final diagnosis was based on the histopathological appearance which was confirmed by immunohistochemical staining of various markers. A review of the literature of previous cases was also carried out. PMID:27161203

Posterior rectus sheath hernia causing intermittent small bowel obstruction.
Lenobel, Scott; Lenobel, Robert; Yu, Joseph
2014-09-01
A posterior rectus sheath hernia is an abdominal wall hernia that is rarely encountered. Owing to its rarity, it can be easily overlooked in the setting of a patient presenting with abdominal pain. We report a case of a posterior rectus sheath hernia that caused intermittent small bowel obstruction. The unusual aspects of this case are that the defect was large, measuring 6 cm in the transverse diameter, and that it contained small bowel within a large portion of the rectus sheath. Because the defect was large and affected nearly the entire posterior rectus sheath, it was difficult to discern on computed tomography until a small bowel obstruction developed. In this case, a limited awareness of this clinical entity contributed to the delay in diagnosis.

We present the case of a 70-year-old man with a giant right-sided retroperitoneal pseudocyst, confirmed histologically after resection to be benign with appearances dissimilar to pancreatic and adrenal tissue. The cyst was noted incidentally on table at the time of laparoscopic surgery. Retroperitoneal pseudocysts most commonly arise from the pancreas and adrenal glands occurring as a result of an inflammatory process. Primary retroperitoneal pseudocysts are a rare entity. This case highlights the importance of examining the patient thoroughly and not focusing on the obvious. The mass was not palpated on initial review prior to listing for surgery, and the patient was asymptomatic from the mass. PMID:27190202

Calcified chronic subdural hematomas are an occurrence rarely seen in neurosurgical clinical practice. And when they occur bilaterally, the radiologic image they present is fascinating, as is the clinical presentation, but their management may be challenging. They have been reported to present with a multitude of neurologic deficits but never with diabetes insipidus, which is described here. Due to the rarity of this pathology, the management protocol is not well defined, though there have been quite a few papers on this condition. This review article gathers information published over the years on this rare entity to suggest a treatment protocol. Copyright © 2016 Elsevier Inc. All rights reserved.

Rectus sheath hematoma (RSH) presenting as acute surgical abdomen is a rare clinical entity. Failing to establish an early diagnosis will probably result in increased morbidity or unnecessary surgical intervention. We describe herein a case of an 85-year-old woman receiving anticoagulants who presented with typical clinical manifestations of acute surgical abdomen and a slightly palpable abdominal mass. Ultrasonography was inconclusive whereas computed tomography scans demonstrated a large right rectus sheath hematoma associated with hemoperitoneum. The patient was treated conservatively with success. It is therefore concluded that RSH must be considered in any elderly patient on anticoagulant therapy who presents with manifestations of acute surgical abdomen.

Solid papillary carcinoma of the breast, a newly-defined entity, is poorly recognized, and its nature and management is still debated. Eleven cases of pure solid papillary breast carcinoma in our archive and 253 cases reported in previous literature were retrospectively analyzed for their clinicopathological features and outcomes. The eleven cases occurred in elderly females. Grossly, all tumors were well-circumscribed and typically composed of solid papillary nodules. The tumor cells were bland-looking with low-grade atypia and mitoses < 5/10HPF. Immunophenotypically, all eleven cases showed positivity for ER and PR, negativity for CK5/6 and HER2, and a low proliferative index of Ki67. Five cases showed scattered positivity for myoepithelial marker p63, and four cases were positive for CK5/6 and CD10 around the nodules, whereas the other cases were completely negative for all myoepithelial markers. Five cases expressed the neuroendocrine marker synaptophysin, and six cases expressed chromogranin. In nine cases, mastectomy and axillary lymph nodes excision were performed, and only one showed micrometastasis in an axillary lymph node. There was no local recurrence or distant metastasis or breast carcinoma related-death during the follow-up periods of 50 months. Out of 253 solid papillary breast carcinomas reported in literature, the percentage of axillary lymph node metastasis was 4/136 (3%), with rare local recurrences and distant metastasis; only three patients died of breast carcinoma. Solid papillary carcinoma of the breast is a rare entity with distinctive clinicopathological features and excellent prognosis and should be distinguished from conventional breast carcinoma to avoid over-treatment.

The authors present an up-to-date review of toxic shock syndrome (TSS) - a life-threatening condition where toxins of the Gram-positive bacteria Staphyloccocus aureus and Streptococcus pyogenes play a key role in the pathogenesis. The authors provide insight into the epidemiology and pathogenesis of the disease and point out the relevant patient history data and clinical signs and symptoms that may indicate progression of TSS. Last but not least, the state of the art diagnostic and therapeutic approaches to early and full blown TSS are summarized. Case reports are presented to illustrate two different etiological forms of this relatively rare nosological entity.
A 5-year-old boy with only fever and giant coronary aneurysms: the enigma of Kawasaki disease?
Vignesh, Pandiarajan; Bhattad, Sagar; Singhal, Manphool; Singh, Surjit
2016-08-01
Epidemiological case definition of Kawasaki disease (KD) by the American Heart Association requires the presence of fever and four of the following: eye signs, oral mucosal changes, skin rashes, limb edema, and unilateral cervical lymphadenopathy. Incomplete KD is a well-known entity where there is lack of some of mucocutaneous features, and this occurs more often in infants. We report a 5-year-old boy with KD and giant coronary aneurysms, who presented only with fever and there is complete lack of skin and mucosal manifestations at presentation.

Aneurysmal Bone cyst (ABC)is a rare benign lesion of the bone which is infrequent in craniofacial region (12%). Rapid growth pattern causing bone expansion and facial asymmetry is a characteristic feature of ABC. Giant cell lesion is another distinct pathological entity. Here we present to you a rare case of dual pathology in an 11 year old female patient who presented with a large expansile lesion in the left hemimandible. All radiographic investigations were suggestive of ABC, aspiration of the lesion resulted in blood aspirate. However only after a histologic examination the dual nature of the lesion was revealed.

Approximately 100 years ago Eugen Bleuler published the most significant contribution to psychiatry by conceptualizing the term schizophrenia as a diagnostic entity. In modern diagnostic manuals Bleuler's concept is only reflected in subordinated criteria, i.e. the negative symptoms. On the occasion of the anniversary of Bleuler's essential publication, the present work aims to exemplify the differences in diagnostic concepts and it will be illustrated that Bleuler's intention to establish his so-called basic symptom as a guideline for diagnostics has to be considered as failed from a present day viewpoint.
Mycosis fungoides of the true vocal cord: a case report and review of the literature.
Maleki, Zahra; Azmi, Farrukh
2010-09-01
Mycosis fungoides is the most common type of cutaneous malignant T cell lymphoma which primarily affects skin. However, extracutaneous manifestation may occur in advanced stages, mostly observed in postmortem studies. We present a case of mycosis fungoides that disseminated to the true vocal cord of a 48-year-old African American man who presented with hoarseness. Only two cases that have also demonstrated a rare involvement of the true vocal cord have been reported in the English literature. In both cases, mycosis fungoides infiltration of the true vocal cord was seen postmortem, along with visceral dissemination of mycosis fungoides. We herein describe a single extracutaneous manifestation of mycosis fungoides in the true vocal cord of a living patient with a 21-year diagnosis of mycosis fungoides. Vocal cord involvement by mycosis fungoides must be considered as one of the differential diagnoses in any mycosis fungoides patients who complain of persistent hoarseness. Awareness of this entity is clinically important due to the necessity of a different management.

Pure uterine lipoma is a rare entity with only a few cases having been reported in the literature. They usually develop in postmenopausal woman and are mistaken for leiomyomas both clinically and on ultrasound examination. Magnetic resonance imaging (MRI) is the best modality for its preoperative diagnosis. Uterine lipoma has been reported in association with other lesions like endometrial carcinoma, cervical carcinoma and struma ovarii. We present a case of pure lipoma of the uterus with a coincidental benign brenners tumor of the ovary in a 60-year-old female. Patient presented with pain in the abdomen and a preoperative diagnosis of leiomyoma was made based on ultrasonography findings. Gross examination revealed a fatty tumor with a nodule in the right ovary. Microscopy confirmed the presence of pure uterine lipoma with a co-existent brenners tumor of the ovary. To the best of our knowledge this is the first case of uterine lipoma to be reported in association with ovarian brenners tumor.

Treatment-related changes can mimic brain tumor progression both clinically and radiographically. Distinguishing these two entities represents a major challenge in neuro-oncology. No single imaging modality is capable of reliably achieving such distinction. While histopathology remains the gold standard, definitive pathological criteria are also lacking which can further complicate such cases. We report a patient with high-grade glioma who, after initially presenting with histopathologically confirmed pseudoprogression 10 months following treatment, re-presented 3 years following concurrent chemoradiation with clinical and radiographic changes that were most consistent with progressive disease but for which histopathology revealed treatment effects without active glioma. This case highlights the potential late onset of treatment-related changes and underscores the importance of histopathologic assessment even years following initial therapy.

Metaplastic Warthin tumor is a rarely seen subtype of Warthin tumor. It can resemble squamous carcinomas histopathologically, because it contains atypical squamous cells on the necrotic surface. Making a diagnosis can become easier by knowing this entity of Warthin tumor well and by correlating the radiologic findings with pathology. In this case presentation, imaging features of a metaplastic Warthin tumor are presented together with its histopathologic findings. When a solid mass with peripheral enhancing cystic-necrotic component and well defined contour and capsule that shows early enhancement and washout is identified with imaging methods in parotid gland, metaplastic Warthin tumor should be indicated in the differential diagnosis before the histopathologic evaluation.

Large calcified subdural empyema.
Sarkar, S; Mazumder, U; Chowdhury, D; Dey, S K; Hossain, M; Nag, U K; Riaz, B K
2012-04-01
Subdural empyema is a known disease entity; however, calcified subdural empyema is uncommon. The authors present a case of an 11-year-old boy in whom there was diagnosed a chronic calcified subdural empyema 10 years after an attack of meningitis. The patient had suffered from generalized tonic clonic seizures occurring 2-6 times in a month. A large fronto-temporo-parietal craniotomy was carried out and the subdural empyema filled with numerous uncharacteristic tissue fragments with thick pus together with the partially calcified and ossified capsule was removed. The empyema mass was found to be sterile for bacteria. After the operation, no epileptic seizure occurred and the boy is on sodium valporate. We must emphasize the unusual occurrence of the chronic subdural empyema presenting with calcification-ossification and large size as observed in our case.
Unexpected metastatic pheochromocytoma - an unusual presentation.
Birrenbach, Tanja; Stanga, Zeno; Cottagnoud, Philippe; Stucki, Armin
2008-01-01
The classic triad of pheochromocytoma consists of episodic headache, sweating, and tachycardia. General clinicians should be aware, however, that this rare entity might present with a wide spectrum of clinical symptoms. We recently observed a noteworthy case of malignant pheochromocytoma where there was a lack of specific symptoms despite an advanced tumor stage. Malignancy is an important cause of mortality. Reliable diagnosis of malignancy depends upon evidence of local invasion, distant metastases, or recurrence. As in our case, new scintigraphic methods, such as 111-In-pentetreotide scintigraphy (Octreoscan), may occasionally reveal 123-I-metaiodobenzylguanidine-negative distant metastases and help to establish an early diagnosis of malignancy. Tumor size, and perhaps even biochemical profile, may be factors increasing the likelihood of a malignant process and may contribute to early identification of patients at risk.
Peripheral odontogenic fibroma: A case report and review
Baiju, C. S.; Rohatgi, Sumidha
2011-01-01
Odontogenic tumors mainly occur as intraosseous growths but sometimes may present in a peripheral location on the gingiva where they are referred to as peripheral odontogenic tumors (POTs) which are a rare entity, the most common of them being the peripheral odontogenic fibroma that is an otherwise uncommon, slowly growing, benign odontogenic neoplasm of the periodontal soft tissues. In fact, peripheral odontogenic fibroma is the only POT that is more frequent than its central counterpart. Although considered to be with a potential to recur after excision, the actual recurrence rate is not known due to paucity of literature. This paper presents a case report along with review of the available literature and reinforces the importance of patient follow-up in addition to radiographic and histological examination of seemingly innocuous gingival exophytic lesions.

Background: Pregnancy luteoma is a rare non neoplastic condition of the ovary. It is usually asymptomatic and found incidentally during imaging in pregnancy or during cesarean section. Pregnancy luteoma can also occur after ectopic pregnancy. Case Presentation: A 30 year old female presented to G.B. Pant Hospital, Andaman and Nicobar Islands institute of Medical Sciences, Port Blair in October 2015 with abdominal pain. After initial investigations, exploratory laporotomy was done for ruptured ectopic pregnancy. Enlarged ovary was removed along with the ruptured portion of fallopian tube. Histopathological examination revealed solid aggregates of large cells with abundant eosinophilic cytoplasm; diagnosis of pregnancy luteoma was given. Conclusion: It must be considered in the differential diagnosis of ovarian masses in pregnant females that early diagnosis of this entity may avoid unnecessary radical surgery. PMID:29062798

Intradiploic epidermoid cyst of the skull is a rare clinical entity that can exceptionally grow to a large size with intracranial extension. The authors report the case of a 38-year-old man with a giant epidermoid cyst of the parietal bone with extra and intracranial extension, presenting with focal neurological symptoms. The diagnosis was suggested at imaging (skull radiographs, CT and MRI), and confirmed at histology. Complete removal of the cyst and its capsule was performed followed by cranioplasty. Postoperatively, the patient was discharged free of symptoms. CT scan provides good evaluation of the bony lesion and may suggest intracranial extension. MRI is superior for evaluation of cerebral compression. The pathogenesis, clinical presentation, diagnostic evaluation and therapeutic management of these rare lesions are reviewed.

Pannus formation and valve thrombus can cause prosthetic valve failure. The authors report the case of a 50-year-old woman who presented to the emergency room with decompensated heart failure secondary to mechanical valve dysfunction. On two-dimensional and transesophageal echocardiography, the patient had severe aortic stenosis and regurgitation. A thrombus seen on the valve was felt to be the etiology of her prosthetic valve failure. She underwent emergent cardiac surgery for aortic valve replacement. Pathology revealed that although a small thrombus was present, extensive pannus was the underlying mechanism of valve dysfunction. Differentiation between pannus and thrombus may have important clinical implications, but this case illustrates that distinguishing between these entities by echocardiographic and clinical criteria may not be possible.
Intravascular Papillary Endothelial Hyperplasia (Masson’s Tumor) of the Radial Artery: A Case Report

Stark, Christopher, E-mail: Christopher.stark@uvmhealth.org; Olsen, Daniel; Morris, Christopher
Intravascular papillary endothelial hyperplasia (IPEH), often referred to as Masson’s tumor, is a benign non-neoplastic vascular lesion of the skin and subcutaneous tissues. Although it is rare, knowledge of the existence of IPEH is important as it can mimic other benign and malignant tumors, most notably angiosarcoma. IPEH remains an incompletely understood entity; however, most consider it to be the result of reactive endothelial proliferation following thrombus formation within a vessel, vascular malformation, or adjacent to a vessel. In this article, we report a case of IPEH arising within an arteriovenous malformation of the radial artery and present accompanying multimodalitymore » imaging and pathology figures. We will also describe the clinical presentation, pathophysiology, histology, imaging features, and management of IPEH.« less
Principles and tools for collaborative entity-based intelligence analysis.
Bier, Eric A; Card, Stuart K; Bodnar, John W
2010-01-01
Software tools that make it easier for analysts to collaborate as a natural part of their work will lead to better analysis that is informed by more perspectives. We are interested to know if software tools can be designed that support collaboration even as they allow analysts to find documents and organize information (including evidence, schemas, and hypotheses). We have modified the Entity Workspace system, described previously, to test such designs. We have evaluated the resulting design in both a laboratory study and a study where it is situated with an analysis team. In both cases, effects on collaboration appear to be positive. Key aspects of the design include an evidence notebook optimized for organizing entities (rather than text characters), information structures that can be collapsed and expanded, visualization of evidence that emphasizes events and documents (rather than emphasizing the entity graph), and a notification system that finds entities of mutual interest to multiple analysts. Long-term tests suggest that this approach can support both top-down and bottom-up styles of analysis.
[Anterior urethral valves and anterior urethral diverticulum, are they same entity?
Calleja Aguayo, E; Hernández Calvarro, A E; Bregante Ucedo, J; Marhuenda Irastorza, C
2015-04-15
We present our experience in the diagnosis and management of anterior urethral valves (AUV) and anterior urethral diverticula (AUD) as well as review of the bibliography. We retrospectively evaluated all the cases of the AUV and AUD treated in our hospital during the last 10 years. The clinical exploration, renal function study and renal and bladder ultrasound were evaluated in all the children. The diagnosis was completed with voiding cystography (VCUG) and cystoscopy as well as nuclear study in the relevant patients. Four patients have been treated in our center. AUV was suspected in those children with narrowing of the anterior urethra and thickened bladder with trabeculations at the VCUG. These findings were noticed in 50% of the patients, which also had a neonatal presentation. The diagnosis was confirmed by cystoscopy that allowed the endoscopic resection at the same procedure. The boys with AUD were managed by excision of the diverticulum with urethroplasty. On the follow up, one patient who had AUV, presented renal involvement in the nuclear scans with normal renal function. In our experience, the AUV and AUD behave as two different entities in terms of clinical presentation and treatment. The AUV have been effectively treated with endoscopic surgery and the AUD have pointed out open surgery, as described in the literature.
Persistent L5 lumbosacral radiculopathy caused by lumbosacral trunk schwannoma
Sharifi, Guive; Jahanbakhshi, Amin
2017-01-01
Schwannomais, usually, benign tumor of nerve sheath that occurs evenly along the spinal cord. Intra-pelvic schwannoma is very rare entity that may arise from lumbosacral nerve roots or from sciatic nerve. Radicular pain of the lower limb as a presenting symptom of pelvic schwannoma is extremely rare. In the current report, the patient is presented with a right sided L5 radicular pain typical of lumbar discopathy. Interestingly, a herniated lumbar disc was noted on lumbosacral magnetic resonance imaging (MRI). In pre-operative studies a large pelvic mass was detected in the right pre-sacral area with solid and cystic components consistent with schwannoma. The patient underwent a low midline laparotomy to evacuate the retroperitoneal mass. Uniquely, we found the tumor to be arisen from lumbosacral trunk not from a root or peripheral nerve. Most cases with intra-pelvic schwannoma present so late with vague abdominal and pelvic discomfort or pain, low back pain, urinary and bowel symptoms because of compressive effect of the tumor, or incidentally following gynecologic work-ups; So, these patients are mostly referred to gynecologists and urologists. A neurosurgeon should have a high degree of suspicion to diagnose such an entity among his or her patients presented with pains typical for discopathy. PMID:28413533

Introduction Polymastia and polythelia may be asymptomatic or cause pain, restriction of arm movement, milk discharge, cosmetic problems or anxiety. Cosmesis is the main indication for surgical excision of accessory breasts in axilla. In addition it also confirms the diagnosis and allays the patient’s fear of harbouring a malignancy. Aim To evaluate the presentation of symptoms, investigations required for diagnosis and the management to improve the treatment protocols in patients with breast diseases. Materials and Methods This retrospective study on breast diseases presenting as supernumerary breasts and nipples was conducted in the Department of Surgery between January 2013 and January 2016 at MMIMS Research and hospital, Mullana, Ambala. Patients were evaluated for breast diseases, either benign or malignant in both genders. A total of 32 cases diagnosed as accessory breasts disease were retrieved from the hospital archive. The clinical and radiological evaluation was done in the form of ultrasound and mammography wherever necessary. Accessory breast tissues were excised under general anesthesia and histopathological examinations were done. Results Out of 32 cases: 1(3.125%) male patient had unilateral and 1(3.125%) male had bilateral accessory nipple, 7 (21.87%) females had unilateral and 1(3.125%) had bilateral accessory nipple, 1 (3.125%) diagnosed as accessory axillary fibroadenoma in female, 16(50%) presented as unilateral and 5 (15.62%) had bilateral swelling in the axilla as accessory breast. Patients underwent surgical excision and in 8(25%) cases z- shaped incision was made in view of better cosmesis. Patients were followed up upto 6 months postoperatively. There were no residual swelling and movements of the arm over the shoulder joint were normal. In 3(9.37%) cases, wound dehiscence occurred; in 2 (6.25%) cases lymphoedema formation was seen. These were successfully managed conservatively. Conclusion As breast swellings either fibroadenoma or carcinoma are common entities to come across everywhere but accessory breasts are rarely encountered especially in rural areas because of less awareness. The study found that there was tendency to neglect the swelling as there were minimal symptoms present. We also came across a rare entity, accessory breast and accessory nipples. A clinician should not ignore such cases taking as simple swelling because of chances of discovering a malignancy can occur. PMID:27891392

Turban pin aspiration syndrome is a new clinical entity afflicting young Islamic girls wearing a turban.The goal of this study was to present our experience in diagnosis and treatment of this new entity, define its clinical and epidemiologic features, and shed a new light on the role of fashion in the increased incidence. A retrospective study in a tertiary university hospital. Review of clinical parameters and epidemiologic features of 26 patients diagnosed with turban pin aspiration syndrome admitted to the Hadassah-Hebrew University Hospitals in Jerusalem from 1990 to 2010. All patients were Muslim females with an average age of 16 years. In all cases, the history was positive for accidental aspiration. Most of the pins were located in the trachea (42%). In 20 cases, the pins were extracted by rigid bronchoscopy without major complications. Fluoroscopy-assisted rigid bronchoscopy was used successfully in three cases. In one case, the object was self-ejected by coughing before the bronchoscopy, and two patients were referred to the chest unit for thoracotomy. Clinicians should be aware of this distinct form of foreign body aspiration, its method of diagnosis, and extraction techniques. A cultural investigation showed a difference in the turban-fastening technique of young girls as compared with their mothers. Removal by rigid bronchoscopy is a safe method with a high success rate and should be considered as the preferred extraction method of choice.

Wandering spleen with horseshoe kidney a rare occurrence.
Than, Da Jun; Ern, Teo Ten; Karim, Khasnizal Bin Abdul
2018-01-01
Wandering spleen is a rare clinical entity in itself, with only 2 cases reported thus far when correlated with congenital under-development of the kidney, it usually happens due to under development of its surrounding ligaments. Herein we present a case of wandering spleen with underlying congenital deformity of horseshoe kidney which requires splenectomy due to late presentation. A 21 year old lady presented with worsening of chronic abdominal pain for 3 years, associated with nausea and vomiting. Physical examination showed a vague mass located at epigastric region. Consecutively, computed tomography images showed a well-defined, oval, hypoechoic spleen extending from center of abdomen up to epigastric region measuring 15.5 × 13 cm with twisted pedicle. Finally the patient underwent surgical treatment. The intraoperative findings were consistent with computed tomography images. The patient made a full recovery and was discharged well. Wandering Spleen was first described by Van Horne during autopsy back in 1667. Its location is maintained by peritoneal attachments such as lienorenal, splenocolic, splenophrenic, gastrosplenic and phrenicocolic ligaments. Among which, the gastrosplenic ligament and lienorenal ligaments are of greatest significance. Patient with a wandering spleen may present asymptomatic, with a movable mass in the abdomen, or with chronic or intermittent abdominal pain because of partial torsion and spontaneous de-torsion of the spleen as in our case. When feasible especially in young patients, splenopexy should always be the first consideration but however if gross infarct has occurred then splenectomy is inevitable to save the patient. Wandering spleen is a unique surgical entity moreover when appeared in congruence with horseshoe kidney. Its diagnosis should be made in prompt to prevent splenic infarction and to try to salvage with splenopexy especially in younger population. However in patient where splenic torsion with infarction has occurred, splenectomy would be the treatment of choice. Copyright © 2018 The Author(s). Published by Elsevier Ltd.. All rights reserved.
Clinical characteristics of keratosis obturans and external auditory canal cholesteatoma.
Park, So Young; Jung, Young Hoon; Oh, Jeong-Hoon
2015-02-01
Keratosis obturans (KO) and external auditory canal cholesteatoma (EACC) have been considered separate entities. While the disorders are distinct, they share many overlapping characteristics, making a correct diagnosis difficult. In the present study, we compared their clinical characteristics and radiological features to clarify the diagnostic criteria. Retrospective case series. Academic medical center. The clinical data of 23 cases of EACC and KO were retrospectively reviewed. The following clinical characteristics were compared between the 2 groups: sex, age, onset of symptoms, follow-up period, audiometric results, and imaging findings on temporal bone computed tomography including bilaterality, location, and the presence of extension to adjacent tissue. The mean age of the EACC group was significantly older than that of the KO group. All of the cases of EACC occurred unilaterally, and bilateral occurrences of KO were observed in 4 of 9 cases. All of the lesions in the KO group were circumferential, and no lesion in the EACC group invaded the superior canal wall. No significant differences in symptoms, such as acute otalgia, otorrhea, and hearing loss, were noted between the 2 groups. The incidence of conductive hearing impairment more than 10 dB was higher in the KO group than in the EACC group. Thus, KO and EACC are 2 distinct disease entities that share common features in clinical characteristics except for predominant age and bilaterality. Conservative treatment with meticulous cleaning of the lesion was successful in most cases with a long-term follow-up. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

The occurrence of rudimentary horn pregnancy is an extremely rare and potentially serious obstetric entity, threatening maternal and fetal outcome. The authors report five cases of rudimentary horn pregnancy, the difficulties in making a proper diagnosis and the therapeutic management of this pathological entity, stressing the importance of transvaginal ultrasound, of pelvic MRI and laparoscopy in the early diagnosis of this type of uterine malformation.
LeadMine: a grammar and dictionary driven approach to entity recognition.
Lowe, Daniel M; Sayle, Roger A
2015-01-01
Chemical entity recognition has traditionally been performed by machine learning approaches. Here we describe an approach using grammars and dictionaries. This approach has the advantage that the entities found can be directly related to a given grammar or dictionary, which allows the type of an entity to be known and, if an entity is misannotated, indicates which resource should be corrected. As recognition is driven by what is expected, if spelling errors occur, they can be corrected. Correcting such errors is highly useful when attempting to lookup an entity in a database or, in the case of chemical names, converting them to structures. Our system uses a mixture of expertly curated grammars and dictionaries, as well as dictionaries automatically derived from public resources. We show that the heuristics developed to filter our dictionary of trivial chemical names (from PubChem) yields a better performing dictionary than the previously published Jochem dictionary. Our final system performs post-processing steps to modify the boundaries of entities and to detect abbreviations. These steps are shown to significantly improve performance (2.6% and 4.0% F1-score respectively). Our complete system, with incremental post-BioCreative workshop improvements, achieves 89.9% precision and 85.4% recall (87.6% F1-score) on the CHEMDNER test set. Grammar and dictionary approaches can produce results at least as good as the current state of the art in machine learning approaches. While machine learning approaches are commonly thought of as "black box" systems, our approach directly links the output entities to the input dictionaries and grammars. Our approach also allows correction of errors in detected entities, which can assist with entity resolution.
