    Hemangiomas are benign vascular tumors. They are the prerogative of the liver and skin. And genitourinary localizations are rare and have only been rarely reported in the prostat, bladder, ureter or the perineum. In the light of published cases, urethral hemangiomas are mostly found in males. Few cases of hemangioma in the female urethra were reported. We report a cavernous hemangioma of the urethra in a 61 years old patient who presented bleeding from the urethra and micturition disorders. Physical examination revealed a tumor 3 cm x 2 polyploid arising from the terminal urethra (urethral hemangioma). We performed surgical resection of the tumor, along with bladder drainage. The postoperative course was simple. We update through a review of the literature aspects of the diagnostic and therapeutic care of the urethral hemangioma.

    Infantile hemangioma (IH) is the most common benign vascular tumour affecting children. Most infantile hemangiomas are self-limiting, but some require specific treatment. Propranolol has been proposed for the treatment of infantile hemangiomas. The aim of this study is to explore the mechanism of action of propranolol for the treatment of infantile hemangiomas and to demonstrate its safety and efficacy through a review of the literature. The non cardioselective bêta-blocker propranolol has been used in a pediatric setting for 40 years and, since 2008, has a new indication. A clearly significant improvement has been observed in the condition of children with complicated IH (10%) treated with propranolol. This new indication has been widely described in the international literature. Various explanations have been put forward for the mechanism of action including a vasoconstrictor, antiangiogenic and apoptotic effect of propranolol on the different cells making up an IH. Overall tolerance is good and the efficacy markedly superior to that of any other treatments used for this purpose. In conclusion, with its good tolerance profile and superior efficacy versus all the other available therapies, propranolol can be considered to be a first-line treatment for complicated IH.

  4. Anastomosing hemangioma of the kidney: a literature review of a rare morphological variant of hemangioma

    PubMed Central

    2015-01-01

    Background Anastomosing hemangioma (AH) of the kidney is a recently described morphological variant of hemangioma. It poses a diagnostic dilemma for clinicians because of its rarity and the overlapping features it shares with other renal vascular tumors. The aim of this paper is to review all the cases of AH of the kidney in the literature. Methods The literature was extensively searched for case reports of AH of the kidney and the clinical and pathological characteristics of the tumor were extracted. Results A total of 45 cases were reviewed. The mean age of presentation was 50 years (range, 15-83 years) and male sex accounted for 68.8% of the cases reviewed. AH of the kidney was mostly unilateral with only 4 cases of bilateral involvement of the kidney. The average size of the tumor is 1.5 cm (range, 0.1-7 cm). Incidental finding of AH of the kidney accounted for 62% of the cases reviewed. The ultrasound findings demonstrated varying echogenicity and the tumor appeared as solid and well demarcated heterogeneous masses on CT. The average follow up of the patients in this review was 26 months (range, 1-156 months). Conclusions AH of the kidney is a rare vascular tumor and a morphological variant of hemangioma. It has a characteristic sinusoidal architecture with a semblance of splenic sinusoids. It has overlapping clinical and imaging features with other vascular tumors of the kidney. Histological review and immunohistochemical studies are essential for accurate diagnosis. AH runs a benign course without evidence of disease recurrence during follow up. PMID:26244138

    Capillary hemangiomas are benign vascular neoplasms. When associated with the spine, these growths frequently involve the vertebral body, but rarely have they been reported to occur as intradural lesions, while even more rarely occurring in a true intramedullary location. We report a rare case of an intramedullary capillary hemangioma of the thoracic spinal cord and a review of the literature. PMID:21139881

    Retroperitoneal hemangiomas are very rare. This paper presents the case of a 71-year-old female patient with giant cavernous hemangioma of the retroperitoneum who underwent surgical treatment for abdominal pain and left lower limb edema. Interventional staged treatment with percutaneous transcatheter arterial embolization prior to surgery was considered. Radical resection of the tumor was performed, which caused the symptoms to abate. Additionally a literature review of cases involving cavernous hemangioma in the retroperitoneal space is presented. No description of retroperitoneal cavernous hemangioma originating from the bowel was found in the analyzed reports. PMID:28096841

  7. Zygomatic Intraosseous Hemangioma: Case Report and Literature Review.

    2017-03-01

    Intraosseous hemangiomas are uncommon intrabony lesions, representing approximately 0.5 to 1% of all intraosseous tumors. Their description varies from "benign vasoformative neoplasms" to true hamartomatous proliferations of endothelial cells forming a vascular network with intermixed fibrous connective tissue stroma. These commonly present as a firm, painless swelling. Intraosseous hemangiomas present more commonly in females than in males and most likely occur in the fourth decade of life. The most common etiology of intraosseous hemangioma is believed to be prior trauma to the area. They have a tendency to bleed briskly upon removal or biopsy, making preoperative detection of the vascular nature of the lesion of significant importance. There are four variants: (1) capillary type, (2) cavernous type, (3) mixed variant, and (4) scirrhous type. Generally most common in the vertebral skeleton, they can also present in the calvarium and facial bones. In the head, the most common site is the parietal bone, followed by the mandible, and then malar and zygomatic regions. Intraosseous hemangiomas of the zygoma are rare entities with the first case reported in 1950 by Schoenfield. In this article, we review 49 case reports of intraosseous hemangioma of the zygoma, and also present a new case treated with excision followed by polyether-ether ketone implant placement for primary reconstruction.

    We report the case of 2 infants born with a lumbar dermal sinus tract and an overlying angiomatous skin lesion referred to our pediatric neurosurgery service for evaluation of a tethered cord. Both infants were born with a lumbar dimple and were found to have a large cutaneous hemangioma without neurologic symptoms. An MRI of the lumbar spine revealed an isointense mass in the dorsal epidural at L(4) with an adjacent mass effect and extension into the overlying soft tissues. The spinal cord also appeared to be tethered with a fatty filum terminale. We performed a lumbar laminectomy and laminoplasty to remove the mass and to release the tethered cord. Pathologic examination confirmed the diagnosis of capillary hemangioma. Several case reports describe spinal capillary hemangiomas in adults, but only one found in the literature describes a case in an infant. We provide a review of the literature of spinal capillary hemangiomas and support the practice of evaluating infants with cutaneous lumbosacral hemangiomas for underlying spinal cord abnormalities.

    Soft tissue hemangiomas are commonly encountered lesions, accounting for 7-10 % of all benign soft tissue masses (Mitsionis et al. J Foot Ankle Surg 16(2):27-9, 2010). While the literature describes the great majority of hemangiomas as asymptomatic and discovered only as incidental findings, they do have the potential to induce reactive changes in neighboring structures (Pastushyn et al. Surg Neurol 50(6):535-47, 1998). When these variants occur in close proximity to bone, they may elicit a number of well-documented reactive changes in osseous tissue (Mitsionis et al. J Foot Ankle Surg 16(2):27-9, 2010; DeFilippo et al. Skelet Radiol 25(2):174-7, 1996; Ly et al. AJR Am J Roentgenol 180(6):1695-700, 2003; Sung et al. Skelet Radiol 27(4):205-10, 1998). However, instances of direct extension into bone by soft tissue hemangiomas--that is, infiltration of the mass's vascular components into nearby osseous tissue--are currently undocumented in the literature. In these cases, imaging plays an important role in differentiating hemangiomas from malignant lesions (Mitsionis et al. J Foot Ankle Surg 16(2):27-9, 2010; Sung et al. Skelet Radiol 27(4):205-10, 1998; Pourbagher, Br J Radiol 84(1008):1100-8, 2011). In this article, we present such a case that involved the sacral spine. Imaging revealed a soft tissue mass with direct extension of vascular components into osseous tissue of the adjacent sacral vertebrae. Biopsy and subsequent histopathologic examination led to definitive diagnosis of soft tissue hemangioma. While MRI is widely regarded as the gold standard imaging modality for evaluating hemangiomas, in this report we describe how CT can aid in narrowing the differential diagnosis when one encounters a vascular lesion with adjacent osseous changes. Furthermore, we review the literature as it pertains to the imaging of soft tissue hemangiomas that occur in proximity to osseous tissue, as well as correlate this case to current theories on the pathogenesis of hemangiomas

    Vertebral hemangiomas are benign vascular lesions of the vertebral column; only 0.9-1.2% of all vertebral hemangiomas cause spinal cord compression. We report a 34-year-old female who was admitted to the neurosurgery clinic with a history of back pain, poor quality of life and easy fatigability for 1.5 years. Her medical history revealed a fall from a height of 2 meters 1.5 years ago. Neurology examination revealed bilateral hypoesthesia below the T8 level and hyperactive deep tendon reflexes in her left leg. Computed tomography scan of the thoracic spine showed T8 vertebral hemangioma, and magnetic resonance imaging showed a T8 hemangioma compressing the spinal cord. Surgical intervention was planned and T8 total laminectomy was performed. The tumor extending into the anterior spinal cord was resected, and T8 vertebroplasty with short segment posterior stabilization and fusion was performed. We aimed to present a new treatment approach for symptomatic vertebral hemangiomas and reviewed the relevant literature.

    Propranolol has recently become the treatment of choice for management of subglottic and airway hemangiomas. This literature review aimed to determine the success rate of propranolol for managing these lesions as well as the rate of rebound growth following propranolol treatment cessation. Literature search involving MEDLINE and Scopus to identify English-language articles. Studies were identified using hemangioma, subglottic or airway, and propranolol for search terms. Studies were eligible for inclusion if they reported the treatment used, individual deidentified patient data, and contained patients without medical or surgical treatment prior to propranolol therapy RESULTS: Initial review included 107 abstracts. Twenty-four articles including case reports and case series met inclusion criteria and were included in the qualitative analysis. Forty-nine patients were included. Twenty-eight (57%) were treated with propranolol alone, and 20 (41%) were treated with a combination of propranolol and a corticosteroid. Thirty-seven (76%) of patients were treated with a dose of 2 mg/kg/d of propranolol. The initial treatment was successful in 43 (88%) of patients. Rebound growth occurred in four (9%) patients. Overall, six (12%) patients underwent surgical resection. Propranolol is efficacious for treating subglottic hemangiomas. Rebound growth does occur in a small subset of patients during the propranolol wean. Close observation for children during weaning of propranolol therapy for subglottic hemangioma is essential. Adjunctive management strategies need to be used in patients with rebound growth. Laryngoscope, 2017. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

    Hemangiomas are benign tumors originating in the vascular tissues of skin, mucosa, muscles, glands, and bones. Although these tumors are common lesions of the head and neck, they rarely occur in the nasal cavity and paranasal sinuses. Cavernous haemangioma of the lateral wall of the nasopharynx has not previously been reported. We examined the clinical, radiological and therapeutic management of cavernous haemangioma of nasopharynx starting from a clinical case of a 26-year-old woman with a history of recurrent and conspicuous epistaxis and left-sided nasal associated severe obstruction. Nasopharynx examination, by flexible endoscopy, showed a cystic mass borne by the left side wall of the nasopharynx, in contact with the soft palate, covered by intact and regular mucosa. Contrast-enhanced computed tomography (CT) scan, confirmed these findings and showed contextual lamellar calcifications and inhomogeneous enhancement. The nasal endoscopic approach (FESS), under general anesthesia, allowed removal of the mass, without complications, after careful hemostasis of arterial branches. It was possible to establish the precise site of origin of the tumor only during the surgical procedure. Histopathological study showed mucosa with extensive vascular proliferation, with framework of lacunar/cavernous haemangioma, also present at lamellar bone tissue level. An unusual site and an unspecific clinical appearance can make diagnosis and treatment of a cavernous hemangioma of the nasopharynx difficult. The nasal endoscopic technique proved to be reliable in terms of adequate exposure and visualization of the lesion, control of bleeding, and complete removal of the mass. PMID:28352748

    Epithelioid hemangioma (EH) is an uncommon benign vascular lesion, also known as angioblastic lymphoid (or angiolymphoid) hyperplasia with eosinophilia, characterized by an unclear etiopathogenesis. It usually affects young to middle-aged adults and develops in the head and neck region, as painless cutaneous or subcutaneous reddish papules or nodules. Large vessels involvement is extremely rare, and to date only two cases affecting the brachial artery have been cited in literature. In this report we present a further case of EH of the brachial artery and review the pertinent literature. PMID:28352744

    Pancreatic hemangiomas are a rare type of cystic tumor, with very few cases reported in the literature. Herein, we present the case of a 28-year-old woman who was admitted to our hospital for abdominal pain. A physical examination failed to reveal any abnormalities that could explain her symptoms. A contrast-enhanced computed tomography showed a multilocular cyst with moderately enhanced septa and fluid-fluid levels in the body and tail of the pancreas. A serous cystadenoma or pseudocyst of the pancreas was initially suspected, and the patient underwent a subtotal pancreatectomy and splenectomy. The pathologic diagnosis was a pancreatic hemangioma. This is the second case of pancreatic hemangioma with fluid-fluid levels reported in the literature. Upon imaging, the presentation of this tumor can resemble serous or mucinous cystadenomas, pseudocysts of the pancreas, and side-branch type intraductal papillary mucinous neoplasms. This report reviews the clinical symptoms, radiologic features, pathologic characteristics, differential diagnoses, and treatment of this rare lesion type. PMID:26290651

    Patient: Female, 55 Final Diagnosis: Anastomosing capillary hemangioma in the left kideny Symptoms: Left flank pain Medication: — Clinical Procedure: Partial nephrectomy Specialty: Diagnostics • Laboratory Objective: Rare disease Background: Vascular tumors of the kidney are rare tumors that are usually diagnosed and confirmed by histopathological examination due to the difficulty in definitive diagnosis by clinical and radiological examination. Anastomosing hemangioma is a rare variant of capillary hemangioma that mimics angiosarcoma. Case Report: Here, we present a case of a 55-year-old female with a history of partial nephrectomy due to clear cell renal cell carcinoma three years earlier, who presented with a contralateral anastomosing capillary hemangioma. The diagnosis was confirmed by histopathology and immunohistochemistry studies. Conclusions: Anastomosing hemangioma is a rare variant of capillary hemangioma. It has a sinusoidal growth pattern which resembles splenic parenchyma. It mimics malignant neoplasms, thus, clinical and radiological examination are not enough for accurate diagnosis. In this paper, we discuss the most crucial differential diagnoses and the pitfalls in diagnosing this rare variant of hemangioma. Furthermore, we present a literature review of all cases reported in the English-language literature. PMID:28286335

    Intraosseous hemangiomas arising from the nasal turbinate are exceedingly rare, with few reported cases in the literature. We describe a 61-year-old man found to have a nasal cavity mass on sinus computed tomograph (CT) and magnetic resonance imaging (MRI). Although an atypical site of occurrence, distinctive internal honeycomb bony trabeculations demonstrated on CT allowed the correct diagnosis of an intraosseous hemangioma to be prospectively proposed by the interpreting radiologist which had direct clinical and surgical impacts.

    Pulmonary sclerosing hemangioma (PSH) is a relatively rare benign tumor. However, as it occurs only rarely, the natural course of the tumor is not well understood. In the present study, a case is presented of a 35-year-old woman who underwent intermittent fevers for more than one year. This case highlighted fever as a rare symptom of PSH. Fever is possibly one of the symptoms of PSH, although it is less likely to occur. Another symptom of the patient was that the tumor grew quickly in two months. The lesion was diagnosed as multiple sclerosing hemangioma of the lung (i.e., PSH), in which papillary, solid and sclerotic patterns appeared. Immunohistochemical evaluation of the lesion revealed positive staining for thyroid transcription factor 1 (TTF1), epithelial membrane antigen (EMA), pancytokeratin (PCK) and cytoskeleton 7 (CK7). In the present case study, the biological activity of PSH was identified to be aggressive. A review of the literature was performed in order to comment further on the clinical and pathological features of this rare disease. PMID:28357098

    Capillary hemangiomas are benign tumors found in the skin and soft tissues in younger people. They occur in the central nervous system only rarely, and intradural occurrence is extremely rare. We report here a 60-year-old man presenting with thoracic girdle pain and progressive gait disturbance. Magnetic resonance images of the thoracic spine showed a 12 × 8 × 20 mm, well-defined intradural mass at the T2 level, compressing the spinal cord laterally. Relative to the spinal cord, the mass was hypo- to isointense on T1-weighted images and relatively hyperintense on T2-weighted images, with strong enhancement on contrast-enhanced T1-weighted images. The patient underwent T1-2 hemilaminectomy with resection of the intradural extramedullary tumor, which showed characteristics of a capillary hemangioma on histologic examination. The patient's symptoms improved following the surgery and no clinical or radiological evidence of recurrence was noted at the 2-year follow-up. We present this case with a review of the literature, highlighting features for differential diagnosis. PMID:25045565

    Hemangiomas are benign dysplasias or vascular tumors consisting of vascular spaces lined with endothelium. Nowadays, radiotherapy for vertebral hemangiomas (VHs) is widely accepted as primary treatment for painful lesions. Nevertheless, the role of surgery is still unclear. The purpose of this study is to propose a novel algorithm of treatment about VHs. This is a case report of an extensive VH and a review of the literature. A case of vertebral fracture during radiotherapy at a total dose of 30 Gy given in 10 fractions (treatment time 2 weeks) using a linear accelerator at 15 MV high-energy photons for extensive VH is reported. Using PubMed database, a review of the literature is done. The authors have no study funding sources. The authors have no conflicting financial interests. In the literature, good results in terms of pain and neurological deficits are reported. No cases of vertebral fractures are described. However, there is no consensus regarding the treatment for VHs. Radiotherapy is widely utilized in VHs determining pain. Surgery for VHs determining neurological deficit is also widely accepted. Perhaps, regarding the width of the lesion, no indications are given. We consider it important to make an evaluation before initiating the treatment for the risk of pathologic vertebral fracture, since in radiotherapy, there is no convention regarding structural changes determined in VHs. We propose a new algorithm of treatment. We recommend radiotherapy only for small lesions in which vertebral stability is not concerned. Kyphoplasty can be proposed for asymptomatic patients in which VHs are small and in patients affected by VHs determining pain without spinal canal invasion in which the VH is small. In patients affected by pain without spinal canal invasion but in which the VH is wide or presented with spinal canal invasion and in patients affected by neurological deficits, we propose surgery.

    1) Describe the origins of the use of propranolol in the treatment of subglottic hemangiomas, 2) Perform meta-analysis of all case reports and series in which propranolol was used to treat subglottic hemangiomas. Literature review and meta-analysis. A total of 61 cases were identified from 19 scholarly articles. Cases were assessed by parameters including age at diagnosis, presence of other hemangiomas, percent airway obstructed, dose of propranolol, treatment duration, age at therapy termination, use of steroids, and treatment failure. Treatment failure was defined as: 1) Need for surgery after initiation of propranolol, 2) Return of symptoms, or 3) Endoscopic worsening/recurrence of hemangioma. All data was subjected to comprehensive statistical analysis. Though not statistically significant, a trend was noted towards a decreased treatment failure rate with increasing doses of propranolol (p = 0.0563). The use of concurrent steroids was associated with a higher failure rate (p = 0.0487). Notably, no associations were observed between the presence of additional hemangiomas, prior surgery, or increased initial percent airway obstruction with treatment failure. Propranolol is rapidly becoming the standard of care in the treatment of subglottic hemangiomas. Despite widespread adoption, the rarity of this condition has limited previous studies to case reports and small series. No evidence-based guidelines exist for proper dosing of propranolol. The results of this meta-analysis suggest a benefit to higher doses of propranolol (3 mg/kg/day), though further investigation is needed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Klippel-Trenaunay syndrome is a congenital vascular anomaly characterized by a triad of varicose veins, cutaneous capillary malformation, and hypertrophy of bone and soft tissue. Gastrointestinal and genitourinary vascular malformations in Klippel- Trenaunay syndrome may present with lower gastrointestinal bleeding and hematuria. The majority of patients with splenic hemangiomatosis are asymptomatic. We herein report a case admitted to the Gastroenterology Clinic with life-threatening hematochezia and symptomatic iron deficiency anemia. The patient's history was remarkable for subtotal cystectomy and enterocystoplasty in December 2002 for vascular malformation, located in the bladder, which presented with hematuria. Although the patient was also diagnosed with colonic varices and splenic hemangiomas at that time, due to the asymptomatic mild intermittent hematochezia and splenic hemangiomas, the patient did not seek any help for rectal bleeding until her admittance to our department for evaluation of massive lower gastrointestinal bleeding. Endoscopy revealed vascular malformations starting from the transitional zone in the rectum extending up to the descending colon. Due to this extensive involvement of the rectum and sigmoid colon, no interventional endoscopic procedure was attempted and she was referred to surgery. A very low anterior resection with double stapling technique was done. Postoperative follow-up has been uneventful for six months since the operation. To the best of our knowledge, this is the first Klippel-Trenaunay syndrome case presenting with lower gastrointestinal bleeding, hematuria and splenic hemangiomas. The literature on the evaluation and management of lower gastrointestinal and genitourinary bleeding in Klippel-Trenaunay syndrome is reviewed.

    Tracheal hemangioma is a rare benign vascular tumor in adults. We reported a case of massive hemoptysis caused by a cavernous hemangioma in a 75-year-old man. This is the first report, to our knowledge, of a tracheal cavernous hemangioma that presented with massive hemoptysis. The lesion was removed with a CO2 laser under rigid laryngoscopy. Endovascular tumors, such as tracheobronchial hemangiomas, should be considered a diagnostic option in cases of massive hemoptysis without a significant underlying lung lesion. PMID:25861344

    Infantile hemangiomas as frequent infancy tumors have been a controversial issue of medical scientists worldwide. Their clinical aspects are various and their physiopathology is yet to be fully understood. Numerous publications outline the characteristics, causes, evolution possibilities and therapeutic approaches. Deciding whether to treat or not is the main question of this kind of pathology. Hemangiomas that have complications or can cause irreversible damage need therapy. This is a brief review of up-to-date information regarding the presentation of infantile hemangiomas and target-therapies. PMID:26528043

    Hobnail hemangioma is a small benign vascular malformation of the superficial and mid-dermis with variable clinical presentation. To review the clinical characteristics of hobnail hemangioma in pediatric patients. A retrospective chart review performed of all histopathologically confirmed cases of hobnail hemangioma from May 2000 to December 2014. Data on demographics, clinical characteristics, and results of immunohistochemical staining were collected. Four male and 2 female patients identified. Congenital lesions were reported in 3 cases. The most common anatomic location was the extremities. Treatment options included observation and surgical excision. Hobnail hemangioma is an uncommon benign vascular malformation. Due to its benign nature, treatment is not required. If treatment is indicated, complete surgical excision appears to be the most effective option. © The Author(s) 2015.

    Background Cavernous hemangiomas of the adrenal gland are rare, benign, non-functioning neoplastic tumors. To our knowledge, 55 cases have been reported in the literature to date. Case presentation We report the first case of a large, non-functioning adrenal cavernous hemangioma that was incidentally found during the preoperative staging workup of a 75 year old woman with left breast adenocarcinoma. Imaging with US, CT scan and MRI showed a heterogeneous 8 cm mass with non-specific radiological features that was located on the left adrenal gland. The mass was surgically excised and pathology revealed an adrenal hemangioma with areas of extramedullar hemopoiesis. Conclusion Although adrenal hemangiomas are rare and their preoperative diagnosis is difficult, they should always be included in the differential diagnosis of adrenal neoplasms. PMID:19193247

    Context Hemangiomas are the commonest benign tumors of the spine. Most occur in the thoracolumbar spine and the majority are asymptomatic. Rarely, hemangiomas cause symptoms through epidural expansion of the involved vertebra, resulting in spinal canal stenosis, spontaneous epidural hemorrhage, and pathological burst fracture. Findings We report a rare case of a 73-year-old woman, who had been treated for two months for degenerative neurogenic claudication. On admission, magnetic resonance imaging and computed tomographic scans revealed a hemangioma of the third lumbar vertebra protruding to the epidural space producing lateral spinal stenosis and ipsilateral nerve root compression. The patient underwent successful right hemilaminectomy for decompression of the nerve root, balloon kyphoplasty with poly-methyl methacrylate (PMMA) and pedicle screw segmental stabilization. Postoperative course was uneventful. Conclusion In the elderly, this rare presentation of spinal stenosis due to hemangiomas may be encountered. Decompression and vertebral augmentation by means balloon kyphoplasty with PMMA plus segmental pedicle screw fixation is recommended.

    Hepatic hemangiomas are benign tumors of the liver consisting of clusters of blood-filled cavities, lined by endothelial cells, fed by the hepatic artery. The vast majority of HH are asymptomatic, most often being discovered incidentally during imaging investigations for various unrelated pathologies. Typical hemangiomas, the so-called capillary hemangiomas, range from a few mm to 3 cm, do not increase in size over time and therefore are unlikely to generate future symptomatology. Small (mm-3 cm) and medium (3 cm-10 cm) hemangiomas are well-defined lesions, requiring no active treatment beside regular follow-ups. However, the so-called giant liver hemangiomas, of up to 10 cm (most commonly) and even 20+ cm in size (according to occasional reports) can, and usually will develop symptoms and complications that require prompt surgical intervention or other kind of therapy. HH belong to the class of hepatic "incidentalomas", so-called because they are diagnosed incidentally, on imaging studies performed as routine examinations or for other reasons than the evaluation of a possible liver mass. Less than half of HH present with overt clinical symptoms, consisting, most often, of upper abdominal pain (this is usually the case for large lesions, which cause the distension of Glisson's capsule). Hepatic hemangiomas require a careful diagnosis to differentiate from other focal hepatic lesions, co-occurring diagnoses are also possible.

    Pancreatic hemangioma is a rare type of benign vascular tumor. Low clinical suspicion and inability of current cross sectional imaging techniques to differentiate it from other pancreatic lesions, contribute to the difficulty in making the correct diagnosis. Without a definitive diagnosis, and due to concern for malignancy, in many instances, surgery is performed. We report a case of pancreas cavernous hemangioma in an 18-year-old female. The patient presented with three-month history of epigastric pain. Physical examination and routine blood tests were normal. Abdominal Computed Tomography scan revealed a 5 cm × 6 cm complex non-enhancing cystic mass in the head of pancreas. Magnetic resonance imaging, endoscopic ultrasonography (EUS) and EUS guided fine needle aspiration cytology were non-diagnostic. Because of uncontrolled symptoms, the patient underwent surgical resection. Histopathology and Immunohistochemical staining confirmed the diagnosis of cavernous hemangioma of pancreas. PMID:26361427

    Background: Congenital hemangiomas are benign vascular tumors, and the intracranial counterpart was described in very few cases. Case Description: A newborn presented with an intracranial tumor associated with an arachnoid cyst, diagnosed by antenatal ultrasound at 37 weeks of gestation. Surgery was indicated due to increased head circumference and bulging fontanelle, and a complete resection of an extra-axial red–brown tumor was performed at the 3rd week of life. Microscopy revealed a hemangioma. Conclusion: Hemangioma is a rare differential diagnosis that must be considered in extra-axial intracranial tumors affecting infants and neonates. The radiological features are not helpful in differentiating from other tumors, and surgery is indicated when the diagnosis is uncertain or whenever there are signs of increased intracranial pressure.

    Intraosseous hemangiomas are one of the rarest lesion of jaw bones (0.5–1%) occurring most commonly in vertebral column, skull bone, and rarely in mandible. Mainly occurs in the second decade of life with female: male predilection (2:1). Origin of hemangiomas is still debatable. World Health Organization considers it as a true benign neoplasm of vascular origin, and many authors believe it to be a hamartoma. It is very difficult to diagnose due to variable clinical and radiological features. A biopsy is not done on a routine basis due to a higher risk of hemorrhage. Management is very difficult because of massive vascular network in that region. Here, we are presenting a case report of a 14-year-old boy with intraosseous hemangioma of right body of mandible, which was treated with en bloc surgical resection of mandible and followed by reconstruction.

    Vascular tumors of the breast are rare and may pose a diagnostic challenge. Breast hemangioma is a very rare benign vascular neoplasm accounting for 0.4% of all breast tumors. It is most commonly detected as an incidental microscopic finding in biopsy specimens obtained for unrelated reasons. We describe here a very rare case of a sinusoidal breast hemangioma in a postmenopausal patient who presented with a palpable breast mass. A complete surgical resection was performed because the tumor exhibited atypical imaging features. We conclude that although in carefully selected cases of breast hemangioma a conservative management with follow up imaging is a reasonable option, in cases with atypical imaging or pathological characteristics a complete surgical resection of the vascular tumor is mandatory in order to exclude the possibility of an underlying angiosarcoma.

    Type and timing of treatment for symptomatic hemangiomas in pregnant females are challenging due to fetus survival and conflicts in neurological recovery. In this article, we report a 40-year-old female patient at pregnancy week 23 with a complicated hemangioma at T1 level. Physical examination revealed an incomplete spastic paraplegia. Patient did not accept any surgery due to child's death risk. Patient was started corticoid treatment and no more weight bearing was allowed. At the 28th week of pregnancy, the patient underwent cesarean section immediately followed by selective arterial embolization, decompression, fixation, and radiotherapy. At two-year follow-up, the patient was pain free, without any signs of local recurrence and with complete neurological recovery. A multidisciplinary approach is mandatory to save the life of the fetus without damaging the spinal cord functions of the mother.

    Introduction Cavernous hemangioma of the skull is a rare pathological diagnosis, accounting for 0.2% of bone tumors and 7% of skull tumors. Usually calvarial bone cavernous hemangioma are associated with a benign clinical course and, despite their enlargement and subsequent erosion of the surrounding bone, the inner table of the skull remains intact and the lesion is completely extracranial. Presentation of a case The authors present the unique case of a huge left frontal bone cavernous malformation with intradural extension and brain compression determining a right hemiparesis. Discussion Calvarial cavernous hemangiomas are benign tumors. They arise from vessels in the diploic space and tend to involve the outer table of the skull with relative sparing of the inner table. More extensive involvement of the inner table and extradural space is very unusual and few cases are reported in literature. To the best of our knowledge, intradural invasion of calvarial hemangioma has not been previously reported. Conclusion Our case highlights the possibility of an aggressive course of this rare benign pathology. PMID:27061482

    Purpose: The current study analyzes the potential role of radiotherapy (RT) in symptomatic vertebral hemangioma (SVH). Methods and Materials: Seven cooperating German institutions collected clinical information, treatment plans, and outcome data for all patients with SVH referred for local RT. Results: From 1969 to 2008, a total of 84 patients with 96 symptomatic lesions were irradiated for SVH. The primary indication for radiotherapy was pain (97.6%), and 28.6% of patients had additional neurological symptoms. RT was performed at a median total dose of 34 Gy, with a median single dose of 2.0 Gy. After receiving a median follow-up of 68 months, the overall patient response rate was 90.5%. Complete symptom remission occurred in 61.9% of patients, 28.6% of patients had partial pain relief, and 9.5% of patients had no pain relief. In 26.2% of patients, radiological signs of reossification were observed in long-term follow-up but not significantly correlated with pain relief. Most importantly, total doses of >=34 Gy resulted in significantly greater symptomatic relief and control rate than total doses of <34 Gy. Conclusions: This study consists of the largest database of cases reported so far using RT for SVH. RT is easy, safe, and effective for pain relief treatment for SVH. Total doses of at least 34 Gy give the best symptomatic response.

    Capillary hemangioma in the cranial cavity is rare. This report describes 2 additional cases presenting shortly after pregnancy and provides a systematic review summarizing clinical experience to date. Case reports were compiled retrospectively. Patient 1 was a 28-year-old woman who presented with a simple partial seizure associated with left-sided visual distortions that progressed to a secondary generalized tonic-clonic seizure. Imaging revealed a contrast-enhancing lesion in the right temporal region adjacent to the transverse sinus, with vasogenic edema and scalloping of the inner table. The angiographic appearance suggested the correct diagnosis. Patient 2 was a 41-year-old woman who presented with progressive visual disturbance 6 months after giving birth to her second child. Subtle symptoms of headache and visual disturbance had commenced during pregnancy. Noncontrasted imaging displayed a homogenous tumor with surrounding vasogenic edema in the occipital region. PubMed and Science Citation Index were reviewed systematically for prior publications. Complete surgical excision was performed in both patients. Neuropathological examination confirmed benign capillary hemangioma consisting of a meshwork of capillary-sized and larger feeder vessels in both instances. Systematic review was based on 20 publications and a total of 24 patients; their clinical, radiological, and surgical features as well as management are summarized. At follow-up, symptoms had resolved and magnetic resonance imaging confirmed complete removal in both patients. Intracranial capillary hemangioma is rare, and treatment is empirical. Review of limited published reports suggests that surgery is the most commonly used treatment and that complete excision seems most likely to prevent further recurrence.

    Anastomosing hemangioma is a recently described, unusual variant of capillary hemangioma which seems to be unique for the genitourinary system, with a particular proclivity for the kidney. Histologically, it is characterized by a unique sinusoidal architecture reminiscent of splenic parenchyma that can lead to concern for angiosarcoma. We herein report a further case of anastomosing hemangioma originating in the right kidney of a 48-year-old Chinese man. The patient had a past medical history significant for hepatocellular carcinoma; this tumor was incidentally identified as an asymptomatic right renal mass during the periodical surveillance of the hepatic cancer. The resected tumor measured 2.5cm in maximum diameter and microscopically demonstrated an overall lobulated growth pattern with alternating cellular areas composed of anastomosing sinusoidal capillary-sized vessels lined by hobnail endothelial cells, and edematous, hyaline paucicellular areas. Cytologically the tumor cells were generally bland and exhibited positivity for CD31, CD34 immunohistochemically. The patient had been in a good status without evidence of tumor recurrence 12 months after the surgery. This rare variant renal hemangioma is in need of more recognition and should not be over-diagnosed as a malignance, particularly angiosarcoma. PMID:23573324

    Reported herein is a renal anastomosing hemangioma which developed slowly in the past four years. A 25-year-old woman was found a mass localized in the upper portion four years ago, and only slow progression in the past four years. She underwent a laparoscopic partial nephrectomy of right kidney and diagnosed as anastomosing hemangioma. On histology the vascular components of the tumor had an anastomosing pattern without well-definite margins. Immunohistochemically, only endothelial markers (CD31, CD34) were expressed on the vascular components of tumor cells. Smooth muscle actin (SMA), cytokeratin (CK), EMA and S-100 and so on were all negative in the epithelioid tumor cells. The patient was alive at 16 months after operation, without any evidence recurrence or metastasis. Anastomosing hemangioma is an extremely rare vascular neoplasm; only 23 cases were previously described until now. Our report of anastomosing hemangioma arising from the kidney with slow progression will improve the knowledge of primary vascular tumors arising in the kidney. PMID:25973131

    Renal hemangioma is a relatively rare benign tumor with a wide range of clinical and radiological presentation, not easy to differentiate preoperatively from a renal cancer. Due to its benign nature complete surgical resection is the recommended therapy and is considered curative. A 73-year old male patient followed-up for a lung carcinoma and a chronic renal failure underwent a CT scan showing a 35-mm mass of the inferior pole of the left kidney. The patient underwent robot-assisted partial nephrectomy with left inferior pole selective warm ischemia. The outcome was favorable and no repercussions on the renal reserve were observed postoperatively. Histopathological characteristics of the surgical specimen were consistent with renal cavernous hemangioma. A robot-assisted operation allows the fine dissection required to carry out a bloodless nephron-sparing surgery without a complete warm ischemia. The use of robot could be noteworthy for nephron-sparing surgery in cases of concomitant chronic renal failure.

    2014-06-01

    A case of intractable hiccup developed by cavernous hemangioma in the medulla oblongata is reported. There have been only five previously reported cases of medullary cavernoma that triggered intractable hiccup. The patient was a 28-year-old man who was presented with intractable hiccup for 15 days. It developed suddenly, then aggravated progressively and did not respond to any types of medication. On magnetic resonance images, a well-demarcated and non-enhancing mass with hemorrhagic changes was noted in the left medulla oblongata. Intraoperative findings showed that the lesion was fully embedded within the brain stem and pathology confirmed the diagnosis of cavernous hemangioma. The hiccup resolved completely after the operation. Based on the presumption that the medullary cavernoma may trigger intractable hiccup by displacing or compression the hiccup arc of the dorsolateral medulla, surgical excision can eliminate the symptoms, even in the case totally buried in brainstem.

    Introduction Scalp congenital hemangiomas (CHs) are rare vascular malformations among infants; they can be associated with an array of complications, including cardiac and cosmetic issues. Here, we report the endovascular treatment of a premature infant with a suspected large right parietal scalp hemangioma and associated high-output cardiac failure. Case description A two-day-old female premature infant (29 weeks gestational age; 1330 g birth weight) was referred by the neonatologists to our department for consultation and potential treatment of a large right parietal CH causing abrupt hypotension and high-output cardiac failure. Doppler ultrasound imaging at bedside revealed areas of arterial-venous shunting from the scalp and the presence of a superior sagittal sinus waveform, consistent with intracranial venous drainage. To alleviate cardiac dysfunction secondary to this lesion, trans-arterial embolization via n-butyl cyanoacrylate (nBCA) glue and deployment of detachable coils was performed via umbilical artery to occlude the right superficial temporal and occipital artery branches supplying the CH. Following treatment, the infant continued to require ventilator management, vasopressor support, and correction of coagulopathy, but by post-operative day two, her condition improved remarkably and the mass size began decreasing. The patient was discharged after a relatively uncomplicated subsequent 2½-month course in the neonatal intensive care unit. Conclusion Endovascular therapy proved effective and safe in treating cardiac failure associated with scalp CH, despite potential complications associated with neuro-interventional surgery in premature infants. Appropriate consideration in this patient population should be given to factors including blood loss, contrast use, radiation exposure, operative time, and possible intra-/post-operative complications.

    Congenital hemangiomas are rare solitary vascular tumors that do not proliferate after birth. They are characterized as either rapidly involuting congenital hemangiomas (RICHs) or noninvoluting congenital hemangiomas (NICHs) based on their clinical progression. NICHs have no associated complications, but are persistent. RICH, while usually asymptomatic, may ulcerate or bleed early in their presentation, but involute quickly during the first few months of life. Hepatic RICHs are not associated with cutaneous RICHs, but may result in high-output cardiac failure due to arteriovenous or portovenous shunting. In the following review, the clinical characteristics and current management specific to congenital hemangiomas is discussed.

    We report three new cases of patients with Sturge-Weber Syndrome and symptomatic retinal detachments from diffuse choroidal hemangiomas successfully treated with photodynamic therapy (PDT) and review medical literature on the available treatment options for choroidal hemangiomas. All patients were treated with a single session of PDT with verteporfin infused at a concentration of 6 mg/m(2) and treated for 83 seconds with 689-nm Zeiss laser that was delivered with total energy level of 50 J/cm(2) with an intensity of 600 mW/cm(2). The exudative retinal detachment (RD) and macular edema completely resolved in all cases by 1-4 months after PDT treatment. Visual acuity improved in all three cases with diminished tumor size in the areas of treatment. One case was followed for 5 months, another for 2 years, and the third case for 6 years, with no recurrence of exudative RD. PDT is an effective treatment option for visual deterioration from exudative retinal detachment in patients with diffuse choroidal hemangiomas.

    Infantile hemangiomas (IHs) are the most common vascular tumors in infants, appearing in early infancy and ultimately regressing with time. Clinical presentation may vary, with a minority of lesions causing impairment of vital function (e.g., respiratory or visual obstruction), permanent scarring, and/or disfigurement. The pathogenesis of IH is complex and poorly understood. Risk factors implicated in their development include preterm birth and placental anomalies. IH presents a myriad of clinical challenges, including correct diagnosis and whether or not to pursue treatment. This article is a review of the current literature regarding pathogenesis, clinical presentation, treatment, and prognosis of IH. Birth Defects Research, 2017.© 2017 Wiley Periodicals, Inc.

    To systematically review studies of laser treatment of infantile hemangioma (IH). We searched multiple databases including MEDLINE® and EMBASE from 1982 to June 2015. Two investigators independently screened studies against predetermined criteria and extracted key data. Investigators independently assessed study risk of bias and the strength of the evidence of the body of literature. We identified 29 studies addressing lasers: 4 randomized controlled trials, 8 retrospective cohort studies, and 17 case series. Lasers varied across studies in type, pulse width, or cooling materials. Most comparative studies (n = 9) assessed variations of pulsed dye laser (PDL) and examined heterogeneous endpoints. Most studies reported on treatment of cutaneous lesions. Overall, longer pulse PDL with epidermal cooling was the most commonly used laser for cutaneous lesions; Nd:YAG was the most commonly used intralesionally. Most studies reported a higher success rate with longer pulse PDL compared with observation in managing the size of IH, although the magnitude of effect differed substantially. CO2 laser was used for subglottic IH in a single study, and was noted to have a higher success rate and lower complication rate than both Nd:YAG and observation. Studies comparing laser with β-blockers or in combination with β-blockers reported greater improvements in lesion size in combination arms versus β-blockers alone and greater effects of lasers on mixed superficial and deep IH. Strength of the evidence for outcomes after laser treatments ranged from insufficient to low for effectiveness outcomes. Strength of the evidence was insufficient for the effects of laser compared with β-blockers or in combination with β-blockers as studies evaluated different agents and laser types. Studies assessing outcomes after CO2 and Nd:YAG lasers typically reported some resolution of lesion size, but heterogeneity among studies limits our abilities to draw conclusions. Studies of laser

    2016-04-01

    Infantile hemangiomas are complex benign vascular tumors that present after birth. Hemangioma lesions have a predictable course of growth, but little is understood about the mechanism behind their development. Infantile hemangiomas are considered proliferative lesions of the endothelial cells. To effectively manage infants with infantile hemangiomas, a clear understanding of the pathogenic pathways is important and can assist the healthcare provider with effective treatment. This understanding will facilitate a relationship of support with the families of affected infants. EBSCO host and Ovid database search for key words of infantile hemangiomas, propranolol, vascular lesion, and proliferative lesion was utilized. Articles on pathophysiology along with recent research studies were include in the search. The use of propranolol is a recent development in the treatment of infantile hemangiomas, which has shown a high rate of response in decreasing the size and reducing the potential for life-long complications. Different studies have shown the same success rate with the use of propranolol but with different variables. As a healthcare team member, better identification and customized care of these patients can reduce the rare but devastating complications of infantile hemangiomas. Future research can help identify the most effective dose and course of propranolol administration.

    Background: Primary intraosseous cavernous hemangiomas (PICH) of the skull represent an infrequent bone tumor. Although some rare cases of PICHs located in the skull base have been published, to our concern only three cases have been reported in the English literature of PICHs arising within the clivus. Case Description: We present the case of a patient presenting an isolated abducens paresis due to a rare PICH of the clivus showing also an unusual destruction of the inner table as well as infiltration of the dura mater. Due to this uncommon infiltrative pattern of an otherwise expected intraosseous tumor, a cerebrospinal fluid (CSF)-fistula occurred while performing a transnasal biopsy. The patient recovered successfully without need of lumbar drainage or re-surgery. Additionally, intratumoral decompression was sufficient to relief the abducens paresis. Conclusions: Our case provides new and meaningful information about clinical features as well as growth pattern of these rare clival tumors. We also discuss the importance of knowing these peculiarities before surgery in order to plan the optimal operative management as well as to avoid complications while approaching PICHs localized in such a delicate cranial region.

    Typical engineering methods utilized to calculate stresses on a roof structure involve simplifying assumptions that render a complex non-linear structure a simple and basic determinate beam. That is, instead of considering the composite action of the entire roof structure, the engineer evaluates only a single beam that is deemed conservatively to represent an affected rafter or top chord of a truss. This simplification based on assumptions of a complex problem is where significant conservatism can be introduced. Empirical data will be developed to evaluate this issue. Simple wood beams will be tested to failure. More complex and complete sections of roof structures that include composite action will also be tested to failure. The results can then be compared. An initial step in this process involves a literature review of any work that has been performed on roof structure composite action. The following section summarizes the literature review that was completed.

    Retinal capillary hemangioma (angiomatosis retinae; von Hippel's disease) is a relatively uncommon vascular tumor. When seen in association with systemic angiomas, it is known as von Hippel-Lindau disease. Untreated, these tumors can cause numerous sight threatening sequelae, including exudative and tractional retinal detachment. Recently, the dye yellow laser has been demonstrated to be a safe and effective method of ablating retinal hemangiomas. This paper discusses the case of a retinal hemangioma that was successfully treated with the dye yellow laser. The current treatment modalities of retinal hemangiomas are reviewed, as well as recent literature on the tunable organic dye laser and its utilization in the treatment of retinal vascular disorders.

    Symptomatic vertebral hemangiomas during pregnancy are rare, as only 27 cases have been reported in the literature since 1948. However, symptomatic vertebral hemangiomas can be responsible for spinal cord compression, in which case they constitute a medical emergency, which raises management difficulties in the context of pregnancy. Pregnancy is a known factor responsible for deterioration of these vascular tumors. In this paper, the authors report 2 clinical cases of symptomatic vertebral hemangiomas during pregnancy, including 1 case of spontaneous fracture that has never been previously reported in the literature. The authors then present a brief review of the literature to discuss emergency management of this condition. The first case was a 28-year-old woman at 35 weeks of gestation, who presented with paraparesis. Spinal cord MRI demonstrated a vertebral hemangioma invading the body and posterior arch of T-3 with posterior epidural extension. Laminectomy and vertebroplasty were performed after cesarean section, allowing neurological recovery. The second case involved a 35-year-old woman who presented with spontaneous fracture of T-7 at 36 weeks of gestation, revealing a vertebral hemangioma with no neurological deficit, but it was responsible for pain and local instability. Treatment consisted of postpartum posterior interbody fusion. With a clinical and radiological follow-up of 2 years, no complications and no modification of the hemangiomas were observed. A review of the literature reveals discordant management of these rare cases, which is why the treatment course must be decided by a multidisciplinary team as a function of fetal gestational age and maternal neurological features.

  20. Papillary hemangiomas and glomeruloid hemangiomas are distinct clinicopathological entities.

    2010-02-01

    The author reviews and compares the clinicopathological features of papillary hemangiomas and glomeruloid hemangiomas, 2 rare, cutaneous intravascular capillary-type vascular lesions with overlapping morphological details. Immunostaining for collagen IV highlighted discriminating features in these lesions. Thin basement membranes and glomeruloid architecture are typical of glomeruloid hemangiomas, whereas papillae with thick mantles of a basement membrane- like matrix enveloping pericytes are prominent in papillary hemangiomas. Thus, collagen IV staining patterns provide further evidence that papillary and glomeruloid hemangiomas represent distinct histopathological entities. This additional technique should allow pathologists to readily distinguish between the lesions and make a proper diagnosis. What is important is that glomeruloid hemangiomas-often presenting in a spectrum of multiple cutaneous vascular lesions, including cherry hemangiomas-are a hallmark of POEMS (acronym for polyneuropathy, oganomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) syndrome and/or multicentric Castleman's disease, whereas papillary hemangiomas clinically present as innocent solitary cutaneous hemangiomas in otherwise healthy individuals.

    Over the past decade, the treatment of infantile hemangiomas has undergone dramatic breakthroughs. This review critically evaluates the latest literature that supports the myriad treatment options for infantile hemangiomas. It chronicles the fading role of steroid therapy and evolution of propranolol use as the major treatment modality. Although propranolol is helping this disease become more of a medical disease and less of a surgical dilemma, the report also reveals a continued search to find nonsystemic treatment options. In summary, this is an evidence-based medicine review for the treatment of infantile hemangiomas.

    Given the widespread use of propranolol in infantile hemangioma (IH) it was considered essential to perform a systematic review of its safety. The objectives of this review were to evaluate the safety profile of oral propranolol in the treatment of IH. We searched Embase and Medline databases (2007-July 2014) and unpublished data from the manufacturer of Hemangiol/Hemangeol (marketed pediatric formulation of oral propranolol; Pierre Fabre Dermatologie, Lavaur, France). Selected studies included ≥10 patients treated with oral propranolol for IH and that either reported ≥1 adverse event or effect (AE) or planned to capture AEs. Data capture was standardized and extracted study design, demographic characteristics, IH characteristics, intervention, and safety outcomes. AEs were assigned a system organ class and preferred term. A total of 83 of 398 identified literature records met the inclusion criteria, covering 3766 propranolol-treated patients. The manufacturer's data for 3 pooled clinical trials (435 propranolol-treated patients) and 1 Compassionate Use Program (1661 patients) were included. AE data were reported for 1945 of 5862 propranolol-treated patients. The most frequently reported AEs included a range of sleep disturbances, peripheral coldness, and agitation. The most serious AEs (atrioventricular block, bradycardia, hypotension, bronchospasm/bronchial hyperreactivity, and hypoglycemia-related seizures) were managed by decreasing doses or temporary/permanent discontinuation of propranolol. Limitations included the variety of included study designs; monitoring, collection, and reporting of AE data; small sample sizes for some articles; and the wide scope of review. Oral propranolol is well tolerated if appropriate pretreatment assessments and within-treatment monitoring are performed to exclude patients with contraindications and to minimize serious side effects during treatment.

    Infantile hemangiomas (IH) are common pediatric tumors. This meta-analysis was performed to review the therapeutic efficacy and safety of pulsed dye laser (PDL) in the treatment of IH. Seven databases were searched, including PubMed, OvidSP, Karger, Elsevier, EMBASE, Web of Science and Wiley Online Library. The review collected the characteristics of year of publication, hemangiomas cases, prior treatment, laser parameters, adverse side, pretreatment symptom, and number of response from all articles. A total of 1580 studies were identified, the first round search retrieved 39 articles met inclusion criteria. Of those, only 13 articles with 1529 hemangiomas were included in the meta-analysis. This meta-analysis demonstrated an overall resolution rate of 89.1% with 6.28% incidence of adverse effect. PDL may be the effective modality to decrease the proliferative phase and accelerate rates of involution and resolution with few adverse events. © The Author 2014.

    According to the International Society for the study of vascular Anomalies, vascular anomalies are classified as vascular neoplasms and vascular malformations. In some vascular lesions, categorization as a neoplasm or malformation has not been established with confidence so far. In order to further clarify the nosology of verrucous hemangioma, we studied 13 cases. To analyze immunohistochemical characteristics of verrucous hemangiomas in order to gain further insight in its histogenesis. We carried out a retrospective review. Immunohistochemical expression for Wilms tumor 1 (WT1), Glut-1 and D2-40 was performed in 13 cases. Immunohistochemistry performed with Glut-1 and WT1 showed positive staining in all lesions. All verrucous hemangiomas lacked D2-40 immunostaining. This is the first report in the literature investigating WT1 in verrucous hemangioma in order to further clarify the nosology of this vascular anomaly. Despite the clinical features of verrucous hemangioma, which are similar to those seen in vascular malformations, verrucous hemangioma exhibited an immunoprofile similar to vascular neoplasms, according to WT1 and Glut-1 positivity. © 2013 John Wiley & Sons A/S.

    Cavernous hemangiomas are the most common benign tumors of the liver, which are now seen more often thanks to common use of newer imaging techniques. A review of the literature on cavernous hemangiomas of the liver, including the author's experience with 14 cases, provides data as a touchstone for discussion of the incidence, etiology, symptoms, pathology, diagnosis including ultrasound, radionuclide imaging, computed tomography and angiography, management including resection, hepatic artery ligation, radiation and corticosteroid, and the natural history of these lesions. The author concludes that surgical resection of cavernous hemangiomas should be undertaken with due concern for the relation between the severity of symptoms and the operative risks involved.

    Hemangiomas are common benign vascular tumors of infancy characterized by a proliferative growth phase followed by very slow inevitable regression (involutive phase) between one to ten years of age, about 60% to 70% of the lesions are found in the head and neck region. There are many treatment modalities reported in the literature for head and neck hemangiomas, including wait and see policy, drug therapy, sclerotherapy (steroids, bleomycin), cryotherapy, isotope radiotherapy, laser therapy, and surgical therapy. There still exist many controversies over the optimal treatment options for individual patient. Based on our clinical experience on 250 cases and literature review, a rational treatment regime for head and neck hemangioma was proposed in this study: (1) As it is not possible to predict, whether a hemangioma will remain small and unproblematic or grow into a very large lesion, early therapy is the only way out of this dilemma. A white or pink macule, a port-wine stain-like lesion initially appearing in the children can be effectively and easily removed by laser, thus preventing a growth in the size in the early stage. (2) The term of "wait and see" should be substituted by "close observation", and this approach should only be reserved for hemangiomas which are without visible growth or in the involutive phase. (3) Systematic drug therapy (steroids, interferon alpha-2a ) should be considered for large hemangioma, multiple hemangiomas, life-threatening hemangiomas and hemangiomas with complications such as ulceration, infection, bleeding, dysfunction, etc. Congestive heart failure, consumptive coagulopathy, and thrombocytopenia are also urgent indications for the institution of corticoid therapy. (4) Growing hemangioma can be treated effectively by systematic drug therapy, sclerotherapy, laser therapy or combined therapy. The argon laser (514 nm in wavelength, 0.5 mm in depth) is useful in the treatment of superficial telangiectasias and small, flat cutaneous

    The purpose of this article was to discuss about the use of corticosteroids in head and neck hemangioma as one of the safest noninvasive therapy, focusing on intralesional steroid injection, including perilesional and infusion, for curing or reducing tumor size. A systematic review was done by means of all English publication in PubMed during the period of 1996 to 2008 using the keywords "hemangioma" and "intralesional steroid injection." The studies involved were retrospective and prospective case reviews on using intralesional steroid injection with or without other treatment modalities. Exclusion criteria included letter to the editor, comment, and discussion. Evaluation was done covering the indication, age and sex of the patients, location of the lesion, reduction in volume and resolution after intralesional steroid injection, including perilesional and infusion, the improvement of symptoms and signs, local and systemic complications, dose, and the number of injections required to achieve the desired clinical and aesthetic results. Using the 7th ed. EndNote program, 81 abstracts were successfully retrieved. Finally, this study limited our analysis to 22 studies. A total of 749 patients received intralesional steroid injections, including perilesional and infusion, with or without other treatment modalities. Age of the participants ranged from 10 days to 4 years (mean, 4.17 months). Six references evaluated the percentage of reduction in volume and size after intralesional steroid injection; 71% revealed excellent clinical response, 23.4% good, 2.96% poor, 2% no response, and 0.6% were lost to follow-up. From the remaining, 82% of the participants revealed improvement in sign and symptoms. Three articles mentioned aesthetic evaluation, and all stated excellent to good outcome. Intralesional steroid injection is a good option for treating head and neck hemangioma at proliferative phase with relatively low complications.

    Subglottic hemangioma is a rare condition that can be potentially life threatening because of airway obstruction. It is common for subglottic hemangioma to be misdiagnosed as croup initially. Infants with a subglottic hemangioma and cutaneous facial hemangiomas in a "beard" distribution should be evaluated for PHACE syndrome. Endoscopic laser resection is effective for subglottic hemangioma but carries a chance of subglottic stenosis, up to 25%. Open excision of subglottic hemangioma is an excellent option, particularly in patients with bilateral or circumferential subglottic hemangioma. It is a more extensive surgery when compared with endoscopic laser resection. Surgeons who do not have access to a pediatric intensive care unit staffed by experienced pediatric intensivists should not use this procedure.

    The phakomatose von Hipple-Lindau (VHL) disease is a multisystem disorder characterized by hemangioblastomas of the central nervous system (CNS), retinal angiomas, and multiple cysts and tumors of the viscera. Retinal capillary hemangiomas are the most common manifestation of VHL disease, which can occur in the optic nerve, where it may simulate disc edema, or in the retinal periphery, which is characterized by massive retinal exudation. Both locations can result in progressive accumulation of exudates leading to a decrease in visual acuity and potentially to a serous retinal detachment. A juxtapapillary hemangioma was observed in a 72-year-old man who presented for a routine examination. The patient was asymptomatic, despite the presence of a trace afferent papillary defect. This finding had to be carefully differentiated from sectoral disc edema. Blood tests, computed tomography (CT), and magnetic resonance imaging (MRI) all had normal results. Fluorescein angiography was a valuable secondary test showing early filling of the vascular network overlying the nerve head and characteristic late hyperfluorescence. There are 2 distinct forms of capillary hemangiomas--the juxtapapillary tumor or the peripheral capillary hemangioma. Although both types are similar histologically, they do vary in their appearance, differential diagnosis, and treatment. In both types, fluorescein angiography is an extremely helpful ancillary test in making the initial diagnosis. This case report reviews the ocular manifestations and systemic findings associated with VHL disease.

    2011-09-01

    To review and evaluate the medical literature on new treatments for periocular infantile (capillary) hemangioma. Recent studies have shown a promising new therapy for infantile hemangioma using nonselective β-blockers, including oral propranolol and topical timolol. Conventional treatments for infantile hemangioma include the use of corticosteroids, laser, surgery, and immunomodulator therapy. Recently, systemic and topical β-blockers have been used to successfully treat infantile hemangioma. The drugs' mechanism of action remains uncertain, but plausible theories include vasoconstriction, modulation of pro-survival signal transduction pathways, and endothelial cell apoptosis. Whereas no life-threatening adverse events from β-blocker treatment have been described, there have been reports of bradycardia, hypotension, bronchospasm, hypoglycemia, and electrolyte disturbances resulting from systemic use of propranolol to treat infantile hemangioma. Sleep and gastrointestinal disturbances have also been frequently reported. Topical timolol application for localized, superficial tumors may confer similar efficacy as oral propranolol while reducing systemic effects. Despite the recent explosion of interest surrounding this novel treatment, current treatment and protocol-monitoring recommendations are based largely on the experience of individual centers. Several randomized controlled studies are currently underway, the results of which will guide future standard-of-care treatment for infantile hemangioma.

    2010-01-01

    Purpose of review Infantile hemangioma is a common vascular tumor with a unique lifecycle: rapid growth in infancy, followed by a period of involution, leading to complete regression. This review summarizes recent studies of molecular mechanisms of hemangioma formation and places new findings and hypotheses in the context of past accomplishments. Recent findings The new work identifies a novel signaling pathway for vascular growth factor and extracellular matrix regulation in vascular endothelial cells and provides a basis for novel therapeutic strategies. In hemangioma-derived endothelial cells defects in a vascular endothelial growth factor receptor/integrin complex reduce the expression of a vascular endothelial growth factor decoy receptor. As a consequence, hemangioma endothelial cells exhibit constitutive vascular endothelial growth factor signaling. Germ-line mutations in components of the growth factor receptor/integrin complex in some hemangioma patients, and somatic mutations in a phosphatase in sporadic hemangioma specimens, raise the possibility that hemangioma formation involves a combination of germline risk factor mutations and somatic mutations, similar to what recent studies have shown is the case for venous malformations. Summary Alterations in pathways that negatively control vascular endothelial growth factor signaling in vascular endothelial cells are responsible for the formation and rapid growth of infantile hemangiomas.

    Benign masses arising from facial bones have been reported several times in the literature. Hemangiomas are one of the uncommon benign tumors. In this study, the authors aimed to present a rare patient of zygomatic intraosseos hemangioma and their management. A 40-year-old woman with a mass in her left lateral cantus admitted to our clinic. Preoperative computed tomography and magnetic resonance imaging revealed an osseos mass in her left zygoma. The authors conclude that it should be kept in mind that although they are very rare benign tumors, intraosseos hemangiomas can cause facial masses. Meticulous radiologic examination can give important clues for differential diagnosis before the surgery.

We report a case of a PICH at the anterior clinoid process in a 66-year-old female presenting with headaches and visual impairment. CT and MR imaging showed a mass in the anterior clinoid process. The lesion showed hyperintensity on T1- and T2-weighted imaging, and gadolinium was homogenously enhanced. The lesion was removed surgically, and histologically confirmed as a cavernous hemangioma. Preoperative examinations could not provide a definitive diagnosis. A brief clinical and radiological review of the literature is presented.

    Three cases of symptomatic cavernous hemangioma of the liver are reported. All three patients have normal angiograms. A review of the literature shows that the diagnosis of hemangioma may be made noninvasively with a high degree of accuracy. Technetium Tc 99m-labeled red blood cell scanning is very specific, while dynamic computed tomography may be more sensitive for small lesions. A combination of the two modalities makes the diagnosis in greater than 90% of cases. Magnetic resonance imaging is also sensitive and specific. Angiography, as shown in these cases, may not only be questionably indicated, but may be misleading. The treatment for symptomatic lesions is resection, and secondary alternatives are discussed.

    OBJECTIVE Vertebral hemangiomas are common tumors that are benign and generally asymptomatic. Occasionally these lesions can exhibit aggressive features such as bony expansion and erosion into the epidural space resulting in neurological symptoms. Surgery is often recommended in these cases, especially if symptoms are severe or rapidly progressive. Some surgeons perform decompression alone, others perform gross-total resection, while others perform en bloc resection. Radiation, embolization, vertebroplasty, and ethanol injection have also been used in combination with surgery. Despite the variety of available treatment options, the optimal management strategy is unclear because aggressive vertebral hemangiomas are uncommon lesions, making it difficult to perform large trials. For this reason, the authors chose instead to report their institutional experience along with a comprehensive review of the literature. METHODS A departmental database was searched for patients with a pathological diagnosis of "hemangioma" between 2008 and 2015. Medical records were reviewed to identify patients with aggressive vertebral hemangiomas, and these cases were reviewed in detail. RESULTS Five patients were identified who underwent surgery for treatment of aggressive vertebral hemangiomas during the specified time period. There were 2 lumbar and 3 thoracic lesions. One patient underwent en bloc spondylectomy, 2 patients had piecemeal gross-total resection, and the remaining 2 had subtotal tumor resection. Intraoperative vertebroplasty was used in 3 cases to augment the anterior column or to obliterate residual tumor. Adjuvant radiation was used in 1 case where there was residual tumor as well. The patient who underwent en bloc spondylectomy experienced several postoperative complications requiring additional medical care and reoperation. At an average follow-up of 31 months (range 3-65 months), no patient had any recurrence of disease and all were clinically asymptomatic, except the

    Abstract Primary intraosseous cavernous hemangiomas (PICHs) are benign vascular tumors that may involve any part of the body. PICH occurs more frequently in the spine and less commonly in skull. The earliest description in the English literature was in 1845 by Toynbee, who reported a vascular tumor arising in the confines of the parietal bone. Skull PICHs do not always have typical radiologic features and should always be considered in the differential diagnosis of malignant skull lesions. We now reviewed and analyzed related literatures in detail with reporting a rare case of PICH in the left front bone that was surgically resected. PMID:26986133

    Parafunctional activities associated with the stomatognathic system include lip and cheek chewing, nail biting, and teeth clenching. Bruxism can be classified as awake or sleep bruxism. Patients with sleep bruxism are more likely to experience jaw pain and limitation of movement, than people who do not experience sleep bruxism. Faulty occlusion is one of the most common causes of bruxism that further leads to temporomandibular joint pain. Bruxism has been described in various ways by different authors.

    Compadrazgo, "coparenthood," is a traditional ritual fictive kinship system that provides a network of mutually supportive relationships in the Mexican American culture. A literature search of CINAHL, Medline, PsychoInfo, and Web of Science was used to identify peer-reviewed journals and original sources. Keywords included comadre, compadrazgo, fictive kin, social support, Mexican, and Mexican American. Additional resources were identified through a focused review of references. Findings from this study indicate knowledge about compadrazgo, is limited to the social organization, historical practices, and a preliminary description of the compadres role. Minimal information is available about the relationship between compadrazgo, and health, and variations in roles and responsibilities of compadrazgo, participants. Frequency of enactment of compadrazgo, responsibilities and barriers to the enactment of social support by compadres remain unknown. Variations in practice have not been explored. Nursing implication include the recommended ways that compadrazgo, can be encouraged or promoted in patient care.

    Hemangiomas are the most common tumor of infancy and childhood, affecting approximately 10% of infants by the age of 1 year. The diagnosis can nearly always be made by the patient's history and findings on physical examination. Prior to the classification system outlined by Mulliken and Glowacki, the natural course of hemangiomas was poorly understood and treatment was inconsistent, ranging from benign neglect to deforming surgical intervention. However, with an improved understanding of the natural course of hemangiomas, as well as advances in anesthesia, laser technology, medical therapy, and surgical methods, an aesthetic approach to facial hemangiomas was developed by the senior author (E.F.W.) and is reviewed in this article.

    Pyomyositis is a primary bacterial infection of the skeletal muscles. It is known as tropical myositis as most cases have been reported in patients living in tropical areas and, until recently, it was considered unusual in the temperate zone. The condition is usually diagnosed late, and for this reason it is followed by an increased morbidity and sometimes a significant mortality rate. A review of the literature indicates a possibly rising incidence in non-tropical areas. This condition should be considered in patients with muscle pain, fever, leucocytosis, elevated ESR and CRP, in tropical and non-tropical countries, in previously healthy patients as well as in patients suffering other health problems, particularly HIV infection. An MRI investigation should be performed early as it is the imaging technique of choice during the first stage of the disease. A case of a primary iliopsoas pyomyositis diagnosed during the initial stage using MRI is presented as an illustration.

    As part of the Filtration task EM-31, WP-2.3.6, which is a joint effort between Savannah River National Laboratory (SRNL) and the Pacific Northwest National Laboratory (PNNL), tests were planned to evaluate crossflow filtration in order to the improve the use of existing hardware in the waste treatment plants at both the Department of Energy (DOE) Savannah River Site (SRS) and Hanford Site. These tests included experiments to try different operating conditions and additives, such as filter aids, in order to create a more permeable filter cake and improve the permeate flux. To plan the SRNL tests a literature review was performed to provide information on previous experiments performed by DOE laboratories, and by academia. This report compliments PNNL report (Daniel, et al 2010), and is an attempt to try and capture crossflow filtration work performed in the past that provide a basis for future testing. However, not all sources on crossflow filtration could be reviewed due to the shear volume of information available. In this report various references were examined and a representative group was chosen to present the major factors that affect crossflow filtration. The information summarized in this review contains previous operating conditions studied and their influence on the rate of filtration. Besides operating conditions, other attempted improvements include the use of filter aids, a pre-filtration leaching process, the backpulse system, and various types of filter tubes and filter coatings. The results from past research can be used as a starting point for further experimentation that can result in the improvement in the performance of the crossflow filtration. The literature reviewed in this report indicates how complex the crossflow issues are with the results of some studies appearing to conflict results from other studies. This complexity implies that filtration of mobilized stored waste cannot be explained in a simple generic sense; meaning an empirical

    Three new cases of spinal cord compression due to vertebral hemangioma are reported. The clinical presentation, with spinal pain, radicular radiation, and paraparesis, is similar to that of primary lymphoma, metastatic tumor, and disc disease. If the characteristic plain film changes of vertical trabeculations and striations are present, the preoperative diagnosis is facilitated, but in the majority of cases these are not seen. In some instances, vertebral body or pedicle erosion is present. A myelographic epidural block will be seen on further study. Spinal arteriography can prove helpful. Surgical decompression results in marked neurological improvement if intervention takes place before the onset of complete paralysis. The authors recommend that the diagnosis of vertebral hemangioma be considered in the differential diagnosis of epidural spinal cord compression whenever considered in the differential diagnosis of epidural spinal cord compression whenever a primary malignant neoplasm cannot be identified.

    Liver hemangiomas are the most common benign liver tumors and are usually incidental findings. Liver hemangiomas are readily demonstrated by abdominal ultrasonography, computed tomography or magnetic resonance imaging. Giant liver hemangiomas are defined by a diameter larger than 5 cm. In patients with a giant liver hemangioma, observation is justified in the absence of symptoms. Surgical resection is indicated in patients with abdominal (mechanical) complaints or complications, or when diagnosis remains inconclusive. Enucleation is the preferred surgical method, according to existing literature and our own experience. Spontaneous or traumatic rupture of a giant hepatic hemangioma is rare, however, the mortality rate is high (36-39%). An uncommon complication of a giant hemangioma is disseminated intravascular coagulation (Kasabach-Merritt syndrome); intervention is then required. Herein, the authors provide a literature update of the current evidence concerning the management of giant hepatic hemangiomas. In addition, the authors assessed treatment strategies and outcomes in a series of patients with giant liver hemangiomas managed in our department.

    Spinal hemangiomas can be categorized into three different groups based on location. Vertebral body (VB) hemangiomas are frequent incidental findings on magnetic resonance (MR) imaging. There is a subdivision of these with spinal epidural extension that have been reported in the literature. Spinal hemangiomas can also be epidural without VB involvement; these are extremely rare with few reported cases in the thoracic epidural spinal column. The diagnosis and imaging characteristics as well as the surgical tools used in gross-total resection of spinal epidural hemangioma are not well understood. The authors present a detailed characterization of a spinal epidural hemangioma in a 30-year-old woman who presented with complaints of gradual onset of low-back pain that worsened over 1 year. The MR imaging findings indicated a large L2-S1 epidural spinal mass causing thecal sac compression. The patient underwent an L2-S1 laminectomy, and a vascular extradural mass was noted on the posterior aspect of the dura mater. Preoperative spinal angiography as well as intraoperative angiography was performed. Total resection of the tumor was achieved using intraoperative embolization with sodium tetradecyl sulfate and microscopic dissection. The postoperative MR imaging findings and clinical outcome were excellent. The findings and use of sodium tetradecyl sulfate in gross-total resection are discussed. The authors also review treatment modalities and demonstrate the utility and effectiveness of intraoperative sodium tetradecyl sulfate in grosstotal resection of large difficult spinal epidural hemangiomas.

    A 58-year-old male was diagnosed esophageal hemangioma during a endoscopy in regular examination. The patient was referred to the department of gastroenterology in our hospital to treatment. Combined endoscopic band ligation (EBL) and endoscopic mucosal resection (EMR) was performed for diagnostic treatment. Histopathological results revealed hemangioma. Even though several approaches such as esophagectomy, endoscopic removal, sclerotherapy, and laser therapy have been used to remove the esophageal hemangiomas, recently less invasive methods were preferred. Here we describe a case of esophageal hemangioma removed by EBL & EMR.

    Cavernous hemangioma is the most common benign tumour of the liver and is found quite commonly during abdominal ultrasonography performed for other diseases. It is often asymptomatic and undergoes enlargement in fewer than 10% of cases. Spontaneous rupture of a giant hepatic hemangioma (diameter > 4 cm) with hemoperitoneum occurs very rarely. Only 32 cases have been reported in a recent review of the medical literature, with an operative mortality of more than 35%. We describe a new case of a giant subcapsular hemangioma localised in hepatic segments II and III in an 84-year-old woman, which ruptured spontaneously into the abdominal cavity and presented with hemoperitoneum and hypovolaemic shock. The hemangioma was diagnosed preoperatively by spiral CAT and treated successfully with emergency hepatic bisegmentectomy.

    2016-01-01

    Hemangioma is the clinical term for a benign vascular neoplasm due to proliferation of the endothelial lining of blood vessels. Their most frequent location is the body skin and oral mucosa. One of the treatment modalities for hemangiomas is intralesional injection of sclerosing agents which cause the damage of blood vessels followed by their obliteration. The objective of the study was to describe the facility of application and evaluate the efficiency of sclerotherapy with aethoxysklerol 1%. Method. The case presented with intraoral submucosal hemangioma of the cheek was treated by intralesional injection of aethoxysklerol 3% diluted in water for injections at a 4 : 1 ratio (0.75%) at the first appointment and 3 : 1 (1%) at the second appointment. The effect of sclerotherapy was evaluated on the following visits in time intervals of two weeks. Results. The hemangioma disappeared without complications after the second injection of aethoxysklerol 1%. The successful results of the study were comparable to the data of literature with variations according to the used sclerosant agent, its concentration, the number of injections, and the intervals between each session. Conclusion. Since sclerotherapy is a very effective, inexpensive, and easy-to-apply treatment, it should be the treatment of choice, especially for intraoral superficial hemangiomas. PMID:27994889

It is one of the most challenging when imaging is not able to differentiate it from an intrameatal vestibular schwannoma. We report a cavernous hemangioma extruding from the internal auditory canal, diagnosed after a left translabyrinthine resection in a 45-year-old man complaining of profound sensorineural hearing loss, with no facial paresis or dizziness. The preoperative differential diagnosis of a vestibular schwannoma was impossible, due to the absence of calcifications that usually characterize temporal bone hemangiomas. Clinical presentation, radiological features and treatment considerations are discussed along with up-to-date review of pertinent literature. When considering an apparent small intra-auditory canal schwannoma, otoneurologists should be aware of the rare possibility of a cavernous hemangioma. Early diagnosis and surgical treatment may improve the functional outcome, possibly preserving neural integrity. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Dr. Juan Rosai has been a consistent contributor to the literature on this topic throughout most of his career, and this article reviews selected cutaneous endothelial lesions that he helped to characterize. They include histiocytoid-epithelioid hemangioma, targetoid-hobnail hemangioma, acquired tufted hemangioma, glomeruloid hemangioma, spindle cell hemangioma, retiform hemangioendothelioma, and angiosarcoma. Two potential simulants of angiosarcoma-papillary intravascular endothelial hyperplasia and cutaneous rudimentary meningocele-meningothelial hamartoma-are also considered.

    Fingers often suffer trauma and the clinician is continuously faced with the difficult task of clarifying the distinction between a hemangioma and a traumatic lesion. This study was undertaken to examine ten cases in which a small skin mass located on a finger had been diagnosed preoperatively as hemangioma. Our results showed that seven masses were confirmed pathologically as hemangioma (five cavernous hemangiomas and two capillary hemangiomas), two as traumatic thrombosis and one varix. The clinical manifestations of the two cases of traumatic thrombosis were related to those of hemangioma. In the varix, endothelial proliferation was observed in the area of the thrombosis. This phenomenon is called "intravascular papillary endothelial hyperplasia", and can confuse the differential diagnosis between a vascular neoplasm and a traumatic thrombosis. Our findings demonstrate that since the traumatic lesions were firmer than the hemangiomas, hardness on physical examination may be a helpful indicator in the differential diagnosis of a hemangioma and a traumatic lesion.

    This article reviews the use and effectiveness of emergency cerclage for women who present with a dilated cervix in the second trimester of pregnancy and seeks to identify predictors of favorable emergency cerclage outcomes. We searched PubMed and the Cochrane Library for the period January 1995 to April 2012 and used the terms "emergency cerclage," "emergency stitch," "rescue cerclage," and "rescue stitch." Thirty-four studies in which transvaginal emergency cervical cerclage was performed in women with a dilated cervix were identified and included. Predictors of poor outcome were prolapsed membranes, evidence of intra-amniotic or systemic infection, symptomatic presentation, cervical dilatation greater than 3 cm, or cerclage after 22 weeks. According to observational and limited randomized controlled trials, the cerclage group did significantly better than the bed-rest group in mean randomization-to-delivery interval, preterm delivery before 34 weeks, and compound neonatal morbidity. The current data suggest that emergency cerclage is associated with a longer latency period and, most often, with better pregnancy outcomes when compared with bed rest. Many of the predictors of adverse outcomes appear to be associated with evidence of inflammation or infection. Obstetricians and gynecologists, family physicians After completing this CME activity, physicians should be better able to review the use and evaluate the effectiveness of emergency cerclage for women who present with a dilated cervix in the second trimester, to identify predictors of favorable emergency cerclage outcomes, and to compare emergency cerclage versus bed rest.

    We describe a rare case of vertebra (intraosseous) hemangioma with bilateral and symmetrical epidural extension causing cord compression in a 24-year-old woman. The epidural component was isointense to cord on both T1 and T2 sequences, and enhanced markedly and homogenously following gadolinium administration. The gradual in onset and progressive nature with the typical enhancing pattern lead the neurosurgeon to the more common diagnosis of spinal meningioma. Epidural extension of vertebral hemangiomas causing cord compression is rarely reported. Review of literatures reveal that cases that have been reported are of unilateral extension into epidural space and of cavernous type. This is the first case report of capillary vertebral (intraossous) hemangioma with bilateral extension through both intervetebral foramen into the epidural space causing myelopathy.

    Hepatic cavernous hemangiomas are benign tumors of the liver that are often an incidental finding. They are usually asymptomatic but may cause symptoms when traumatized, may bleed spontaneously, or may produce pain by virtue of their large size and mass effect. A retrospective analysis of the clinical presentation, liver function tests, and diagnostic imaging procedures in 20 patients with hepatic hemangiomas is presented and the literature is reviewed. The 20 patients had 27 mass lesions as seen on liver scintigraphy, computed tomography, or sonography. Technetium-99m-labeled red blood cell flow studies and blood pool scintigrams showed delayed filling of the mass lesions, diagnostic of hemangiomas. This finding was not encountered in any other type of lesion. A new diagnostic algorithm is proposed in which flood-flow and blood-pool scintigraphy play a more prominent role in the diagnostic workup.

    Objectives This systematic review identifies and reviews both peer-reviewed and 'grey' literature, across a range of disciplines and from diverse sources, relating to the condition of children living in mountain communities in low- and middle-income countries. Findings The literature on poverty in these communities does not generally focus on the particular vulnerabilities of children or the impact of intersecting vulnerabilities on the most marginalised members of communities. However, this literature does contribute analyses of the broader context and variety of factors impacting on human development in mountainous areas. The literature on other areas of children's lives-health, nutrition, child mortality, education, and child labour-focuses more specifically on children's particular vulnerabilities or experiences. However, it sometimes lacks the broader analysis of the many interrelated characteristics of a mountainous environment which impact on children's situations. Themes Nevertheless, certain themes recur across many disciplines and types of literature, and point to some general conclusions: mountain poverty is influenced by the very local specificities of the physical environment; mountain communities are often politically and economically marginalised, particularly for the most vulnerable within these communities, including children; and mountain communities themselves are an important locus for challenging and interrupting cycles of increasing inequality and disadvantage. While this broad-scale review represents a modest first step, its findings provide the basis for further investigation.

    Hemangioma of the rib is a rare benign vascular tumor. Herein, we report a 63-year-old man presenting with hemangioma of the left sixth rib. An osteolytic eccentric expansive mass with calcification and focal cortical disruption was detected on chest computed tomography (CT). The mass showed low 2-deoxy-2-[18F]-fluoro-D-glucose (18F-FDG) avidity on positron emission tomography. The patient underwent resection of the left sixth rib. Based on the histopathology findings, a diagnosis of cavernous hemangioma was made. Rib hemangiomas and malignant lesions appear similar on CT scans; therefore, most cases of rib hemangiomas reported in the literature were treated with rib resection. However, rib hemangiomas should be included in the differential diagnosis of an asymptomatic patient if an osteolytic expansive lesion containing sunburst calcifications with low 18F-FDG avidity is observed on a CT scan.

    We report a case of a cystic abdominal mass on ultrasound which presented a diagnostic dilemma at 32 weeks gestation. A presumptive antenatal diagnosis of a subcapsular liver hematoma (SCH) was made based on the location and ultrasound appearance similar to SCH seen in pediatric and adult patients. Sequential evaluation of the mass showed an evolving ultrasound appearance which reinforced our initial impression of a subcapsular hematoma of the fetal liver. Postnatal ultrasound confirmed the resolving SCH as well as a previously undetected echo bright lesion characteristic of an infantile focal hemangioma directly adjacent to the resolving SCH.

    1991-02-01

    We report a case of right ventricular hemangioma which is extremely rare. It was situated on the anterior wall of the right ventricle and protruded into the out flow tract. Aortography revealed that the main feeding artery was the conus brunch. Operation was done under cardiopulmonary bypass. The tumor was situated between LAD and RCA and resected incompletely, because of the fear that complete removal would occlude blood flow of both LAD and RCA. Histological examination disclosed intramuscular hemangioma. The postoperative course was uneventful. To our knowledge, this is the second resected case in the Japanese literature and the eighth case in the world literature.

    A great deal of concern is recently being expressed relative to the playing of tackle football by adolescent Canadians. The purpose of this literature review is to try to summarize the important data from the available world literature. Very few Canadian statistics are available. Most of the data comes from United States experience. Tackle football injury is examined from various perspectives: 1. Equipment 2. Mechanisms of injury 3. Types of injury, with some emphasis on epiphyseal injury 4. Prevention 5. Comparison with other sports Although no “hard and fast” conclusion is drawn, the paper tends to show that: 1. Football is dangerous 2. Football is damaging to many body systems 3. Prevention of injury is difficult under present conditions 4. Alternate games, such as soccer and rugby seem to provide the same benefits with less catastrophic injuries

    Reestablishing blood flow and allowing the continuation of root development are some of the objectives of pulp revascularization. This procedure is currently indicated for teeth with incomplete root formation as an alternative to the traditional treatment of apecification, which consists of inserting calcium hydroxide paste into the root canal for a determined time period in order to induce the formation of a calcified barrier. Although it is considered as the most classically employed therapy, the permanence of the paste for long time periods may lead to the weakening of the root due to hygroscopic properties, as well as proteolytic activities of calcium hydroxide. Therefore, there has been a permanent search for alternatives which allow the full development of immature teeth. Revascularization has emerged as such an alternative, and a range of treatment protocols can be found in the scientific literature. The aim of this paper is to accomplish a literature review concerning this issue.

  11. REVIEW OF PLUTONIUM OXIDATION LITERATURE

    SciTech Connect

    Korinko, P.

    2009-11-12

    A brief review of plutonium oxidation literature was conducted. The purpose of the review was to ascertain the effect of oxidation conditions on oxide morphology to support the design and operation of the PDCF direct metal oxidation (DMO) furnace. The interest in the review was due to a new furnace design that resulted in oxide characteristics that are different than those of the original furnace. Very little of the published literature is directly relevant to the DMO furnace operation, which makes assimilation of the literature data with operating conditions and data a convoluted task. The oxidation behavior can be distilled into three regimes, a low temperature regime (RT to 350 C) with a relatively slow oxidation rate that is influenced by moisture, a moderate temperature regime (350-450 C) that is temperature dependent and relies on more or less conventional oxidation growth of a partially protective oxide scale, and high temperature oxidation (> 500 C) where the metal autocatalytically combusts and oxidizes. The particle sizes obtained from these three regimes vary with the finest being from the lowest temperature. It is surmised that the slow growth rate permits significant stress levels to be achieved that help break up the oxides. The intermediate temperatures result in a fairly compact scale that is partially protective and that grows to critical thickness prior to fracturing. The growth rate in this regime may be parabolic or paralinear, depending on the oxidation time and consequently the oxide thickness. The high temperature oxidation is invariant in quiescent or nearly quiescent conditions due to gas blanketing while it accelerates with temperature under flowing conditions. The oxide morphology will generally consist of fine particles (<15 {micro}m), moderately sized particles (15 < x < 250 {micro}m) and large particles (> 250 {micro}m). The particle size ratio is expected to be < 5%, 25%, and 70% for fine, medium and large particles, respectively, for

    Ongoing instability in the nursing workforce is raising questions globally about the issue of nurse turnover. A comprehensive literature review was undertaken to examine the current state of knowledge about the scope of the nurse turnover problem, definitions of turnover, factors considered to be determinants of nurse turnover, turnover costs and the impact of turnover on patient, and nurse and system outcomes. Much of the research to date has focused on turnover determinants, and recent studies have provided cost estimations at the organizational level. Further research is needed to examine the impact of turnover on health system cost, and how nurse turnover influences patient and nurse outcomes.

  13. Improving intelligence: a literature review.

    Buschkuehl, M; Jaeggi, S M

    2010-05-01

    Intelligence is associated with performance on a wide range of cognitive tasks and is a reliable predictor for educational and professional success. Therefore, the development of effective training regimens that aim to improve intelligence is of high interest. In recent years, there has been accumulating evidence that certain interventions have a positive impact on intelligence. The aim of the present paper is to provide a literature review on such studies. Despite promising results, we conclude that there are still many unknown variables and that the mechanisms that underlie improvements in intelligence are not well understood. More work is needed in order to disentangle these involved processes and to further refine existing training regimens.

    The aim of the study was to report the results of a systematically conducted literature review of empirical studies about healthcare organizations' ethics and management or leadership issues. Electronic databases MEDLINE and CINAHL yielded 909 citations. After a two stage application of the inclusion and exclusion criteria 56 full-text articles were included in the review. No large research programs were identified. Most of the studies were in acute hospital settings from the 1990s onwards. The studies focused on ethical challenges, dilemmas in practice, employee moral distress and ethical climates or environments. Study samples typically consisted of healthcare practitioners, operational, executive and strategic managers. Data collection was mainly by questionnaires or interviews and most of the studies were descriptive, correlational and cross-sectional. There is need to develop conceptual clarity and a theoretical framework around the subject of organizational ethics and the breadth of the contexts and scope of the research needs to be increased.

    In the medical literature, there is little known about vaginal wind, though from clinical expertise, it turns out to be a consistent and underreported problem. The aim of this review was to collect the available literature about the different aspects of vaginal wind. A systematic literature search was conducted using three databases until December 2015. The search strategy was built using relevant synonyms of vaginal wind. Study characteristics were extracted. Risk of bias, the quality of the relevant studies and the level of evidence was judged. Eleven studies met the inclusion criteria. Vaginal wind occurs on random movements and during or after coitus. The prevalence ranges from one to 69%. The pathophysiology is unclear and the incidence unknown. Known risk factors are vaginal delivery and urinary incontinence. Provoking factors are coitus, digital stimulation, cunnilingus and exercising. Female sexual function is decreased. The sexual function of male partners with vaginal wind is not influenced. Overall vaginal wind leads to a decrease in the quality of live and can have cause social isolation. The treatment is related to the cause and mainly not successful. Tampons can be used for treatment as well as prevention. Vaginal wind is an underestimated health issue with a severe impact on sexual functioning. Adequate research is needed regarding the influence of sexual activity, weight, age, parity, the underlying pathophysiological mechanisms, prevention and treatment. Copyright © 2017 Elsevier B.V.

    Capillary hemangioma (capillary lobular hemangioma) and cavernous hemangioma (venous malformation) are relatively common oral tumors/malformations and are characterized by increased numbers of normal and abnormal blood vessels. However, the causes of these lesions are not well understood. CD105 (endoglin) is predominantly expressed in proliferating blood endothelial cells (ECs). We analyzed expressions of CD105, CD34, von Willebrand factor, Ki-67, cyclooxygenase-2 (COX-2), and vascular endothelial growth factor (VEGF)-A in 31 capillary hemangiomas and 34 cavernous hemangiomas. Staining scores were calculated as the product of the proportion score and intensity score. Morphologically normal oral mucosa specimens (n = 10) were simultaneously evaluated as normal controls. As compared with cavernous hemangiomas and normal controls, capillary hemangiomas had higher staining scores for CD105, VEGF-A, and COX-2. The Ki-67 labeling index was significantly higher in capillary hemangiomas than in cavernous hemangiomas and normal controls (P < 0.01). These findings suggest that the biological characteristics of capillary and cavernous hemangiomas are quite different. The ECs of capillary hemangiomas actively proliferated and were generally regulated by VEGF-A. In contrast, the ECs of cavernous hemangiomas lacked proliferative activity. These results suggest that angiogenesis and vasodilatation of pre-existing blood vessels are important in the development of capillary hemangioma and cavernous hemangioma, respectively.

    Microscopic colitis (MC) refers to chronic inflammation of the colon which is characterized by histologic changes at the level of a radiologically and endoscopically normal mucosa. It is a common cause of chronic non-bloody diarrhea that occurs primarily in older individuals; however, there are few studies in the literature with strong scientific evidence compared to other inflammatory bowel diseases (IBD), which limits the knowledge of physicians and pathologists. This article aims to review the information on MC, describing diagnostic methods and drugs available for treatment. We conducted a search of the Pubmed database and CAPES Portal using the keywords "microscopic colitis", "collagenous colitis", "lymphocytic colitis", and "review" for selection of articles published between 1996 and 2015 related to the topic. Based on the studies discussed in this review, we conclude that MC is a relatively new gastrointestinal disorder, most studies are incipient particularly with respect to pathophysiology and immunology, and budesonide is the best documented short-term treatment. However, further studies are needed to elucidate the best strategy for treatment in the long term.

    2016-03-01

    Genital infantile hemangiomas are vascular anomalies that often require complex management and interdisciplinary care. Propranolol was first used to treat patients with infantile hemangiomas in 2008 and has since gained acceptance as first-line therapy. We review the presentation, course, management and outcomes of all cases of genital infantile hemangiomas managed by propranolol administration at a single institution from April 2010 to July 2014. During the study period 9 patients with genital infantile hemangiomas were referred to our hemangioma treatment clinic. Propranolol was initially administered under careful outpatient monitoring at a dose of 1 mg/kg daily in 8 patients. One patient, a 700 gm premature infant, was started on therapy in the inpatient setting at 0.5 mg/kg daily, given the history of prematurity. All patients underwent successful increase of dose to at least 2 mg/kg for the observation phase after tolerating the starting doses. One patient discontinued propranolol prematurely per parental request due to concern regarding peripheral vasoconstriction. Otherwise, no patient demonstrated significant hypotension, symptomatic bradycardia, hypoglycemia or other major side effect requiring treatment discontinuation. All patients who continued the treatment protocol had excellent response to therapy. Propranolol therapy for genital infantile hemangiomas was successfully initiated and the dosage increased in 9 young children without significant side effects and with marked improvement in all patients who continued on treatment. Propranolol is the only Food and Drug Administration approved therapy for treatment of patients with this vascular anomaly and should be considered first-line therapy for genital infantile hemangiomas.

    Propranolol has been used successfully in a limited number of children with infantile hemangiomas. This multicenter retrospective study describes the efficacy and adverse effects of propranolol in infantile hemangioma. Seventy-one infants with infantile hemangiomas were treated with oral propranolol, 1 mg/kg/12 hours, for at least 12 weeks. A photograph based severity scoring assessment was performed by five observers to evaluate efficacy, utilizing a scoring system of 10 as the original infantile hemangioma before treatment and 0 as completely normal skin. The mean of the five independent measurements was used in the analysis. Propranolol was a rapid and effective treatment for infantile hemangiomas at 4 weeks (p < 0.001), at 8 weeks (p < 0.001 compared to the 4 wks value), at 12 weeks (p < 0.05 compared to the 8 wks value), and thereafter up to 32 weeks (p < 0.01 compared to the 16 wks value). The response of infantile hemangiomas to propranolol was similar regardless of sex, age at onset of treatment, type of involvement (segmental and nonsegmental), facial segments affected, special locations (eyelid, nasal tip, and parotid region), ulceration, and depth of infantile hemangiomas. Very few side effects were reported; mainly agitated sleep in 10 of 71 patients. In the series of patients in this study, oral propranolol 2 mg/kg/day was a well-tolerated and effective treatment for infantile hemangiomas. Prospective studies are needed to establish the exact role of propranolol in the treatment of infantile hemangiomas. © 2011 Wiley Periodicals, Inc.

    2005-01-01

    This review summarizes the literature on pathological buying published during the past 15 years. Pathological or compulsive buying is defined as frequent preoccupation with buying or impulses to buy that are experienced as irresistible, intrusive, and/or senseless. The buying behavior causes marked distress, interferes with social functioning, and often results in financial problems. Studies on the phenomenology, diagnosis, classification, comorbidity, epidemiology, and treatment are presented. Pathological buying should be diagnosed as impulse control disorder not otherwise specified (ICD-10 F63.9). Psychiatric comorbidity is frequent, particulary mood, anxiety, substance use, eating, impulse control and obsessive-compulsive disorders. The positive results of pharmacological treatment with antidepressants (usually SSRI) and opioid antagonists could not be confirmed in controlled trials. A disorder specific cognitive-behavioral group treatment manual was published in USA. A controlled study is currently conducted in USA and since 2003 at the Department of Psychosomatics and Psychotherapy at the University Hospital Erlangen.

    Regeneration and tissue repair processes consist of a sequence of molecular and cellular events which occur after the onset of a tissue lesion in order to restore the damaged tissue. The exsudative, proliferative, and extracellular matrix remodeling phases are sequential events that occur through the integration of dynamic processes involving soluble mediators, blood cells, and parenchymal cells. Exsudative phenomena that take place after injury contribute to the development of tissue edema. The proliferative stage seeks to reduce the area of tissue injury by contracting myofibroblasts and fibroplasia. At this stage, angiogenesis and reepithelialization processes can still be observed. Endothelial cells are able to differentiate into mesenchymal components, and this difference appears to be finely orchestrated by a set of signaling proteins that have been studied in the literature. This pathway is known as Hedgehog. The purpose of this review is to describe the various cellular and molecular aspects involved in the skin healing process. PMID:27828635

    Background and aims. An ideal root canal filling material should completely seal the entire root canal space and block communication between the root canal system and its surrounding tissues; it should also be nontoxic, noncarcinogenic, non-genotoxic, biocompatible, insoluble in tissue fluids and dimensionally stable. Bonding to dentin is a promising property, which can prevent leakage and improve the sealing ability of root canal filling materials. Resilon was developed and rec-ommended initially because the existing rootcanal filling materials did not bond to root canal dentin. Since its introduction in 2004, numerous reports have been published regarding various aspects of this material. The aim of this literature review is to present investigations regarding Resilon’s physical and chemical properties and leakage studies. Materials and methods. A review of the literature was performed by using electronic and hand searching methods for Resilon from May 2004 to April 2012. Results. There are many published reports regarding Resilon. The searchshowed that Resilon is composed of a parent polymer, polycaprolactone or Tone, which is a biodegradable aliphatic polyester, with filler particles consisting of bioactive glass, bismuth oxychloride and barium sulfate. It possesses some antibacterial and antifungal properties. It is a promising material for root canal filling. Despite the presence of numerous case reports and case series regarding these applications, there are few designed research studies on clinical applications of this material. Resilon has some drawbacks such as high cost. Conclusion. Resilon seals well and is a biocompatible material. However, more clinical studies are needed to confirm its efficacy compared with other materials. PMID:24082982

    Solares, Roberto; Romero, Maria Isabel

    2004-01-01

    Supernumerary premolars appear to be more common than previously estimated. The purpose of this report was to review most of the cases published in the dental literature since 1932. The authors found that supernumerary premolars occur 3 times more in males than in females, indicating a possible sex-linked inheritance, with the highest frequency of occurrence in the mandibular premolar region (74%). They are also the most common supernumerary teeth in the mandibular arch (7%), and their incidence is 1% (1 in 157)-much higher than previously reported. Maxillary supernumerary premolars were found to occur at a lower rate (26%). The possible mechanisms of development are described, with a localized hyperactivity of the dental lamina being the most widely accepted theory. Recurrence of supernumerary premolars after being surgically removed has been reported in 8% of the cases reviewed. Patients with a previous history of anterior conical or tuberculated supernumerary teeth at an early age have a 24% possibility of developing single or multiple supernumerary premolars at a later age. Early diagnosis and appropriate follow-up with panoramic radiographs is extremely important. Various treatment recommendations are also discussed.

  7. Voyeurism: a review of literature.

    PubMed

    Smith, R S

    1976-11-01

    The most striking thing about the literature on voyeurism is the relative lack of material in print. In the present work, the author was able to find only 15 articles and no books that deal specifically with voyeurism. Of the 57 references compiled for this review, not one involves an experimental manipulation of variables. An attempt is made to review as many aspects of voyeurism as possible, giving illustrative case material whenever available. The areas of troilism and coprophilia are covered in some detail to establish to what degree they belong to the deviation of voyeurism. Theory of perversion has centered around the psychoanalytic and behavioral schools because of the lack of material from other approaches. The voyeur is found to be a relatively young man of low socioeconomic status, who sociosexually is said to be "not retarded but a late bloomer." He is prone to minor crimes and not major offenses. It is suggested that moyeurism be considered a deviation from normal sexual behavior and that deviations are not in and of themselves criminal behavior. At present, punishment is genera-ly mild but highly variable and unpredictable. Treatment is usually analysis or group therapy, but other forms of therapy such as aversion and avoidance conditioning are being attempted with increasing success.

    Background Postlicensure data has identified a causal link between rotavirus vaccines and intussusception in some settings. As rotavirus vaccines are introduced globally, monitoring intussusception will be crucial for ensuring safety of the vaccine programs. Methods To obtain updated information on background rates and clinical management of intussusception, we reviewed studies of intussusception in children <18 years of age published since 2002. We assessed the incidence of intussusception by month of life among children <1 year of age, seasonality, method of diagnosis, treatment, and case-fatality. Findings We identified 82 studies from North America, Asia, Europe, Oceania, Africa, Eastern Mediterranean, and Central & South America that reported a total of 44,454 intussusception events. The mean incidence of intussusception was 74 per 100,000 (range: 9–328) among children <1 year of age, with peak incidence among infants 5–7 months of age. No seasonal patterns were observed. A radiographic modality was used to diagnose intussusception in over 95% of the cases in all regions except Africa where clinical findings or surgery were used in 65% of the cases. Surgical rates were substantially higher in Africa (77%) and Central and South America (86%) compared to other regions (13–29%). Case-fatality also was higher in Africa (9%) compared to other regions (<1%). The primary limitation of this review relates to the heterogeneity in intussusception surveillance across different regions. Conclusion This review of the intussusception literature from the past decade provides pertinent information that should facilitate implementation of intussusception surveillance for monitoring the postlicensure safety of rotavirus vaccines.

  12. Cardiac Cavernous Hemangioma Coexisting With Pulmonary Cavernous Hemangiomas and Giant Hepatic Hemangioma.

    PubMed

    Wang, Chunping; Chen, Hao; Sun, Lin; Mei, Yunqing

    2017-02-01

    We describe a case of cardiac cavernous hemangioma with coexisting pulmonary cavernous hemangiomas and hepatic hemangioma. A 35-year-old woman who had previously received a living donor liver transplant to cure giant hepatic hemangioma was seen because of chest pain. A cardiac neoplasm and multiple pulmonary nodules were detected. The tumor was surgically removed, and biopsy specimens were taken from the lung nodules. Histopathologic examination confirmed that both lesions were cavernous hemangiomas. The patient was discharged without adverse events postoperatively. Cardiac hemangioma is an extremely rare entity; the present case is unique for its multiorgan involvement. Suspicion of this entity should be aroused if the imaging manifestation suggests a vascular nature.

  13. Geopressured habitat: A literature review

    SciTech Connect

    Negus-de Wys, Jane

    1992-09-01

    A literature review of the geopressured-geothermal habitat is summarized. Findings are presented and discussed with respect to the principal topics: Casual agents are both geological and geochemical; they include disequilibrium compaction of sediments, clay diagenesis, aquathermal pressuring, hydrocarbon generation, and lateral tectonic compression. The overall physical and chemical characteristics of the habitats are dictated by varying combinations of sedimentation rates, alteration mineralogy, permeability, porosity and pressure, temperature, fluid content and chemistry, and hydrodynamic flow. Habitat pressure seals are considered in terms of their formation processes, geologic characteristics, and physical behavior, including pressure release and reservoir pressure recharge on a geologic time scale. World-wide occurrence of geopressured-geothermal habitats is noted. The main thrust of this topic concerns the U.S.A. and Canada; in addition, reference is made to occurrences in China and indications from deep-sea vents, as well as the contribution of paleo-overpressure to habitat initiation and maintenance. Identification and assessment of the habitat is addressed in relation to use of hydrogeologic, geophysical, geochemical, and geothermic techniques, as well as well-logging and drill-stem-test data. Conclusions concerning the adequacy of the current state of knowledge and its applicability to resource exploration and development are set forth, together with recommendations for the thrust of future work.

    This article examines how to synthesise and critique research literature. To place the process of synthesising the research literature into context, the article explores the critiquing process by breaking it down into seven sequential steps. The article explains how and why these steps need to be kept in mind if a robust comprehensive literature search and analysis are to be achieved. The article outlines how to engage in the critiquing process and explains how the literature review needs to be assembled to generate a logical and reasoned debate to examine a topic of interest or research in more detail.

    Since their introduction in 1991, propeller flaps are increasingly used as a surgical approach to loss of substance. The aim of this study was to evaluate the indications and to verify the outcomes and the complication rates using this reconstructing technique through a literature review. A search on PubMed was performed using "propeller flap", "fasciocutaneous flap", "local flap" or "pedicled flap" as key words. We selected clinical studies using propeller flaps as a reconstructing technique. We found 119 studies from 1991 to 2015. Overall, 1,315 propeller flaps were reported in 1,242 patients. Most frequent indications included loss of substance following tumor excision, repair of trauma-induced injuries, burn scar contractures, pressure sores and chronic infections. Complications were observed in 281/1242 patients (22.6%) occurring more frequently in the lower limbs (31.8%). Partial flap necrosis and venous congestion were the most frequent complications. The complications' rate was significantly higher in infants (<10 years old) and in the older population (>70 years old) but there was not a significant difference between the sexes. Trend of complication rate has not improved during the last years. Propeller flaps showed a great success rate with low morbidity, quick recovery, good aesthetic outcomes and reduced cost. The quality and volume of the transferred soft tissue, the scar orientation and the possibility of direct donor site closure should be considered in order to avoid complications. Indications for propeller flaps are small- or medium-sized defects located in a well-vascularized area with healthy surrounding tissues.

    2012-11-01

    As faculty members, we frequently find that first-year doctoral students in nursing are confused about how to conduct a systematic integrated literature review. This could be due to its vague definition and a lack of recent literature that provides directions for conducting a systematic integrated literature review. This article aims to provide directions for conducting a systematic integrated literature review by identifying the essential components of published literature reviews in nursing. To achieve this goal, the literature was searched by using the keywords nursing, systematic, and review in multiple databases. A total of 267 articles were selected and are included in this systematic integrated literature review. The articles were then sorted by study design and analyzed in six areas of interests. Finally, a practical guideline for conducting systematic integrated literature reviews is proposed based on the analysis of the literature.

    Major liver resection during pregnancy is extremely rare. When required, the associated physiologic and anatomic changes pose specific challenges and greater risk for both mother and fetus Materials and methods: Three cases of major liver resection during pregnancy due to different etiologies are presented. The relevant literature is reviewed and discussed. We present 3 cases of major liver resection due to giant liver hemangioma with Kasabach-Merrit syndrome, giant hydatid cyst, and intrahepatic cholangiocarcinoma, at gestational week (GW) 17, 19, and 30, respectively. All patients had an uneventful postoperative course, continued the pregnancy and gave birth at GW 38. Major liver resection can be performed safely during pregnancy. A multidisciplinary team of surgeons, anesthesiologists and gynecologists, in a highly experienced tertiary hepatobiliary center, should be involved.

  2. Hemangioma of the Interatrial Septum: CT and MRI Features

    2011-02-15

    Hemangioma of the heart is a rare primary benign tumor mainly appearing as enhancing, homogenous, well-circumscribed mass. We report a case of a 61-year-old asymptomatic woman, whose echocardiography showed a cardiac mass, which was described as the atypical myxoma of the right atrium. For further imaging, contrast-enhanced computed tomography and cardiac magnetic resonance imaging were undertaken, which showed a tumor located in the interatrial septum with imaging characteristics of hemangioma. In the literature, cardiac hemangioma is usually described as an intensely enhancing mass. In our opinion, early peripheral puddling of contrast material with filling in on delayed images is a typical pattern of its enhancement. This characteristic, in addition to high signal intensity on T2-weighted images, allows differentiation of a hemangioma from other benign and malignant tumors.

    2009-03-15

    The incidence of vertebral hemangiomas as the most common benign spinal neoplasms has been differently reported from 10 to 27% based on autopsy series, plain X-rays and MRI reviews. In this study, we reviewed consecutive 782 standard spinal MRI with axial and sagital T1 weighted and T2 weighted images looking for hemangiomas. In this study, the incidence of hemangioma was 26.9%, more common in females (30%) than males (23%), in older age group and in lumbar spine. Most hemangiomas (65%) were less than 10 mm in diameter. Multiple hemangiomas were seen in 33% of cases. The results of this study are similar to another Mediterranean study reported based on MRI findings, but differ from other reports using X-ray or autopsy as diagnostic tool, suggesting the influence of either the race or the sensitivity of the diagnostic tool on the incidence of vertebral hemangioma.

  7. Biology of Infantile Hemangioma

    2014-01-01

    Infantile hemangioma (IH), the most common tumor of infancy, is characterized by an initial proliferation during infancy followed by spontaneous involution over the next 5–10 years, often leaving a fibro-fatty residuum. IH is traditionally considered a tumor of the microvasculature. However, recent data show the critical role of stem cells in the biology of IH with emerging evidence suggesting an embryonic developmental anomaly due to aberrant proliferation and differentiation of a hemogenic endothelium with a neural crest phenotype that possesses the capacity for endothelial, hematopoietic, mesenchymal, and neuronal differentiation. Current evidence suggests a putative placental chorionic mesenchymal core cell embolic origin of IH during the first trimester. This review outlines the emerging role of stem cells and their interplay with the cytokine niche that promotes a post-natal environment conducive for vasculogenesis involving VEGFR-2 and its ligand VEGF-A and the IGF-2 ligand in promoting cellular proliferation, and the TRAIL-OPG anti-apoptotic pathway in preventing cellular apoptosis in IH. The discovery of the role of the renin–angiotensin system in the biology of IH provides a plausible explanation for the programed biologic behavior and the β-blocker-induced accelerated involution of this enigmatic condition. This crucially involves the vasoactive peptide, angiotensin II, that promotes cellular proliferation in IH predominantly via its action on the ATIIR2 isoform. The role of the RAS in the biology of IH is further supported by the effect of captopril, an ACE inhibitor, in inducing accelerated involution of IH. The discovery of the critical role of RAS in IH represents a novel and fascinating paradigm shift in the understanding of human development, IH, and other tumors in general. PMID:25593962

    We describe for the first time a rare coexistence of a cardiac cavernous hemangioma with multiple pulmonary cavernous hemangiomas. Computed tomography revealed bilateral pulmonary nodules, left pleural effusion, and pericardial effusion. Positron emission tomography showed a pericardial neoplasm. Pathologically, multiple large dilated vascular spaces, lined by a single layer of endothelial cells and filled with blood, were revealed in both the cardiac tumor and the pulmonary nodules. Immunohistochemical examination of the lining cells showed positivity for CD31, FLI1, FVIII, and CD34. Taken together, these findings led to the diagnosis of cardiac cavernous hemangioma and multiple pulmonary cavernous hemangiomas.

    Alveolitis are infectious complications following the dental extraction. They appear under two forms: dry, characterized by a painful syndrome and uninhabited alveolus, and suppurative, which becomes identified by provoked pain and alveolus filled. Their etiopathogenesis remain a subject of interrogation because of the rarity of studies concerning this complication. Nevertheless, treatment is mainly favorable by a sedation of the pain and the startup of a physiological healing. From this article, we are going to review their clinical forms, their etiology as well as the followed treatment.

    Psychological resilience is comprised of an adaptive functioning standard before the current and accumulated risks of life. Furthermore, it has a comprehensive range of psychological resources which are essential to overcome adversities, such as personal competences, self-beliefs and interpersonal control which interact with the social networks support. The objectives are to show the concepts of psychological resilience in elderly, relative to dominant theoretical models and the main data about psychological resilience in aging, found in an international and Brazilian review from 2007 to 2013. The descriptors "resilience, psychological resilience and aging", "resiliência e envelhecimento, velhice e velho", were used in PubMed, PsychInfo, SciELO and Pepsic databases. Fifty three international and eleven national articles were selected. The international articles were classified in four categories: psychological and social coping resources, emotional regulation before stressing experiences, successful resilience and aging and correlates, and resilience measures. The Brazilian articles were grouped in three: psychological and social resources, resilience in carers and theory review. Articles on psychological resources and on emotional regulation prevailed as key factors associated with psychological resilience in aging.

    Abstract Introduction: We report the case of a multicentric Castleman disease (MCD) with initial renal involvement. Although the renal involvement in this case was typical of MCD, it constitutes a rare presentation of the disease, and in our case the renal manifestations led to the haematological diagnosis. Clinical Findings/Patient Concerns: The patient was admitted for fever, diarrhea, anasarca, lymphadenopathies and acute renal failure. Despite intravenous rehydration using saline and albumin, renal function worsened and the patient required dialysis. While diagnostic investigations were performed, right hemiplegia occurred. There was no anemia or thrombocytopenia. Diagnoses: Kidney biopsy was consistent with glomerular thrombotic microangiopathy (TMA). Lymph node histology was consistent with hyalin-vascular variant of Castleman disease. Outcomes: Given the renal and neurological manifestations of this MCD-associated TMA, the patient was treated with plasma exchange during one month, and six courses of rituximab, cyclophosphamide and dexamethasone. The evolution was favorable. Conclusion: Although rare, this diagnosis is worth knowing, as specific treatment has to be started as soon as possible and proved to be efficient in our case as well as in other reports in the literature.

    2016-06-01

    Introduction Professor Archibald Cochrane, after whom the Cochrane Collaboration is named, was influential in promoting evidence-based clinical practice. He called for "relevant, valid research" to underpin all aspects of healthcare. Systematic reviews of the literature are regarded as a high quality source of cumulative evidence but it is unclear how truly systematic they, or other review articles, are or 'how systematic is systematic?' Today's evidence-based review industry is a burgeoning mix of specialist terminology, collaborations and foundations, databases, portals, handbooks, tools, criteria and training courses. Aim of the review This study aims to identify uses and types of reviews, key issues in planning, conducting, reporting and critiquing reviews, and factors which limit claims to be systematic. Method A rapid review of review articles published in IJCP. Results This rapid review identified 17 review articles published in IJCP between 2010 and 2015 inclusive. It explored the use of different types of review article, the variation and widely available range of guidelines, checklists and criteria which, through systematic application, aim to promote best practice. It also identified common pitfalls in endeavouring to conduct reviews of the literature systematically. Discussion Although a limited set of IJCP reviews were identified, there is clear evidence of the variation in adoption and application of systematic methods. The burgeoning evidence industry offers the tools and guidelines required to conduct systematic reviews, and other types of review, systematically. This rapid review was limited to the database of one journal over a period of 6 years. Although this review was conducted systematically, it is not presented as a systematic review. Conclusion As a research community we have yet to fully engage with readily available guidelines and tools which would help to avoid the common pitfalls. Therefore the question remains, of not just IJCP but

    Glomeruloid hemangioma is a rare, histologically distinctive, cutaneous, benign vascular tumor, originally described by Chan et al. Glomeruloid hemangioma appears specific to polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes syndrome (POEMS), and is usually, but not always, related to Castleman's disease. We herein report two cases with glomeruloid hemangioma, without any features of the POEMS syndrome. Glomeruloid hemangioma requires a high index of suspicion for diagnosis. It could rarely present as a solitary finding, without any evidence of an underlying POEMS syndrome. PMID:23716835

    2013-01-01

    The concept of lamellar keratoplasty (LK) is not new. However, newer forms of lamellar keratoplasty techniques have emerged in the last decade or so revolving around the concept of targeted replacement of diseased corneal layers. These include anterior lamellar keratoplasty (ALK) techniques that aim to selectively replace diseased corneal stroma and endothelial keratoplasty techniques aiming to replaced damaged endothelium in endothelial disorders. Recent improvements in surgical instruments and introduction of new techniques as well as inherent advantages such as preservation of globe integrity and decreased graft rejection have resulted in the reintroduction of LK as an acceptable alternative to conventional PK. In this review, indications, benefits, limitations, and outcomes of various anterior and posterior lamellar keratoplasty techniques are discussed. PMID:24223301

  18. Review literature on uterine carcinosarcoma.

    PubMed

    Singh, Rajendra

    2014-01-01

    Carcinosarcoma of the uterus is a rare gynaecological neoplasm, which is also known as malignant mixed mesodermal tumor. Traditionally this tumour has been regarded as a subtype of uterine sarcoma, and its origin remains controversial. The exact nature and prognosis was not clear in the past. It is believed that uterine carcinosarcoma have a Mullerian duct origin and have a capacity to differentiate into various mesenchymal and epithelial components. Regarding the histogensis, various theories have been given; of which 'conversion theory' was broadly accepted. Carcinosarcoma are mostly of monoclonal origin with the carcinomatous component being the driving force. This type of tumor is broadly divided into two groups, homologous and heterologous, depending on the characteristics of the stroma or mesenchymal components of endometrial tissue. It is more frequent in black women and postmenopausal women. Radiation is a possible etiological factor but the exact etiology is not known yet. However, tamoxifen may induce carcinogenesis in some patients. Its clinical feature is very similar to endometrial carcinoma i.e. postmenopausal vaginal bleeding, have a very aggressive behavior and a poor prognosis. This pelvic malignancy is treated by multimodality therapy including surgery, chemotherapy and radiotherapy. Here we are reviewing old concepts about the disease and modern understandings of the origin, classification, pathogenesis and recent advances in the treatment of the uterine carcinosarcoma.

  19. Prospective study of the frequency of hepatic hemangiomas in infants with multiple cutaneous infantile hemangiomas.

    Multiple cutaneous infantile hemangiomas have been associated with hepatic hemangiomas. Screening of infants with five or more cutaneous infantile hemangiomas with abdominal ultrasound is often recommended. The aim of this study was to determine the frequency with which hepatic hemangiomas occur in infants with five or more cutaneous infantile hemangiomas compared to those with one to four cutaneous infantile hemangiomas and to characterize the clinical features of these hepatic hemangiomas. A multicenter prospective study of children with cutaneous infantile hemangiomas was conducted at pediatric dermatology clinics at Hemangioma Investigator Groups sites in the United States, Canada, and Spain between October 2005 and December 2008. Data were collected, and abdominal ultrasonography was performed on infants younger than 6 months old with five or more cutaneous infantile hemangiomas and those with one to four cutaneous infantile hemangiomas. Twenty-four (16%) of the 151 infants with five or more cutaneous infantile hemangiomas had hepatic hemangiomas identified on abdominal ultrasound, versus none of the infants with fewer than five (p = 0.003). Two of the 24 infants with hepatic hemangiomas received treatment specifically for their hepatic hemangiomas. Infants with five or more cutaneous infantile hemangiomas have a statistically significantly greater frequency of hepatic hemangiomas than those with fewer than 5. These findings support the recommendation of five or more cutaneous infantile hemangiomas as a threshold for screening infants younger than 6 months old for hepatic hemangiomas but also demonstrate that the large majority of these infants with hepatic hemangiomas do not require treatment.

    Klippel-Trenaunay syndrome is a congenital vascular anomaly characterized by a triad of varicose veins, cutaneous capillary malformation, and hypertrophy of bone and (or) soft tissue. Gastrointestinal vascular malformations in Klippel-Trenaunay syndrome may present with gastrointestinal bleeding. The majority of patients with splenic hemangiomatosis and/or left inferior vena cava are asymptomatic. We herein report a case admitted to the gastroenterology clinic with life-threatening hematochezia and symptomatic iron deficiency anemia. Due to the asymptomatic mild intermittent hematochezia, splenic hemangiomas and left inferior vena cava, the patient did not seek any help for gastrointestinal bleeding until his admittance to our department for evaluation of massive gastrointestinal bleeding. He was referred to angiography because of his serious pathogenetic condition and inefficiency of medical therapy. The method showed that hemostasis was successfully achieved in the hemorrhage site by embolism of corresponding vessels. Further endoscopy revealed vascular malformations starting from the stomach to the descending colon. On the other hand, computed tomography revealed splenic hemangiomas and left inferior vena cava. To the best of our knowledge, this is the first Klippel-Trenaunay syndrome case presenting with gastrointestinal bleeding, splenic hemangiomas and left inferior vena cava. The literature on the evaluation and management of this case is reviewed.

    This article reviews the research literature on gay fathers, and includes brief historical perspectives and statistical data. The major portion of the article compares studies of gay fathers with other groups such as lesbian mothers and nongay fathers. Because the literature is sparse, and the research has severe limitations such as small sample size, few definitive statements about these men can be made with certainty. Even so, tentative generalizations are proposed. The article concludes with some suggestions for future research.

    Objective This review integrates the literature on cavity liners and current concepts of pulp protection with the aim of establishing a better understanding of the role of calcium hydroxide as a cavity liner. Materials and methods A search was conducted through PubMed, MEDLINE, and Ovid for articles with the criteria for the following terms: cavity liners and bases, pulp protection, and calcium hydroxide liners. No specific inclusion or exclusion criteria were applied as to what articles would be included in this review. It was hoped that the extent of the literature reviewed would be as comprehensive as possible. Conclusion This review underlines the fact that calcium hydroxide liners should only be used in the deepest spots in the cavity where the remaining dentine thickness is ≤0.5 mm. A protective layer of resin-modified glass ionomer should always follow the application of calcium hydroxide liners. PMID:28761378

    2017-06-01

    Pyogenic granulomas are benign, reactive, typically superficial vascular lesions that can be idiopathic or arise secondary to trauma, underlying vascular malformations, infections, physiologic or pathologic endocrine changes, and hormone therapy. Deep-seated/subcutaneous pyogenic granulomas (DSPG) are rarely seen in any age group. Pediatric DSPGs can be a clinical and pathologic challenge because these lesions mimic other vascular lesions, including kaposiform hemangioendothelioma, infantile hemangiomas and vascular malformations. Retrospective search of DSPG excised at Cincinnati Children's Hospital Medical center between June 2010 and June 2011 was conducted. Clinical information was obtained from patient charts and histologic slides were retrieved and reviewed. Of the 106 cases of pyogenic granuloma, 4 (3.8%) were diagnosed as DSPG. We report the details of those 4 cases and compare them with the other pediatric DSPG cases reported in the literature. We also review the histologic differential diagnosis of DSPG in pediatric population. Our results suggest that these lesions may not be as rare as inferred by literature, but, rather, underdiagnosed. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  6. TRANSPORT THROUGH CRACKED CONCRETE: LITERATURE REVIEW

    SciTech Connect

    2012-05-11

    Concrete containment structures and cement-based fills and waste forms are used at the Savannah River Site to enhance the performance of shallow land disposal systems designed for containment of low-level radioactive waste. Understanding and measuring transport through cracked concrete is important for describing the initial condition of radioactive waste containment structures at the Savannah River Site (SRS) and for predicting performance of these structures over time. This report transmits the results of a literature review on transport through cracked concrete which was performed by Professor Jason Weiss, Purdue University per SRR0000678 (RFP-RQ00001029-WY). This review complements the NRC-sponsored literature review and assessment of factors relevant to performance of grouted systems for radioactive waste disposal. This review was performed by The Center for Nuclear Waste Regulatory Analyses, San Antonio, TX, and The University of Aberdeen, Aberdeen Scotland and was focused on tank closure. The objective of the literature review on transport through cracked concrete was to identify information in the open literature which can be applied to SRS transport models for cementitious containment structures, fills, and waste forms. In addition, the literature review was intended to: (1) Provide a framework for describing and classifying cracks in containment structures and cementitious materials used in radioactive waste disposal, (2) Document the state of knowledge and research related to transport through cracks in concrete for various exposure conditions, (3) Provide information or methodology for answering several specific questions related to cracking and transport in concrete, and (4) Provide information that can be used to design experiments on transport through cracked samples and actual structures.

  7. Thyroid hemangiomas diagnosed on sonography.

    Park, Sung Hee; Kim, Soo Jin; Jung, Hyun Kyung

    2014-04-01

    Primary thyroid hemangiomas are extremely rare, and only a few cases have been previously reported. Primary hemangiomas are developmental anomalies resulting from the inability of the angioblastic mesenchyme to form canals. Thyroid hemangiomas are generally considered difficult to diagnose preoperatively because of their low incidence and nonspecific imaging findings. Here we report 2 cases of thyroid hemangiomas that were diagnosed correctly on preoperative sonography. Our cases showed similar sonographic findings, such as well-circumscribed hypoechoic lesions with internal channel-like linear lines, and bloody content was aspirated during fine-needle aspirations. Our report shows that thyroid hemangiomas can be diagnosed correctly by sonography with or without confirmation of bloody content in the lesions by fine-needle aspiration.

    2012-01-01

    INTRODUCTION Cavernous hemangioma of the adrenal gland is a rare non-functioning benign neoplasm. PRESENTATION OF CASE A 62-year-old woman with chronic obstructive pulmonary disease was diagnosed as having an incidental non-functioning adrenal tumor. Because of the impossibility of ruling out the presence of malignancy, conventional surgical resection was carried out. The histopathology revealed a 12.5 cm × 11.5 cm × 8 cm adrenal mass with large and lacunae vascular spaces lined with mature endothelial cells. These findings were compatible with cavernous hemangioma. DISCUSSION The majority of patients in the literature underwent surgical resection due to the impossibility of excluding malignancy, because of related symptoms in patients with large masses, or because of the risk of spontaneous tumoral rupture. CONCLUSION These tumors are quite infrequent. Due to the low frequency and the lack of specific symptoms, most adrenal hemangiomas are diagnosed postoperatively. PMID:23287064

    2013-01-01

    Infantile hemangiomas are the most common benign vascular tumors in infancy and childhood. As hemangioma could regress spontaneously, it generally does not require treatment unless proliferation interferes with normal function or gives rise to risk of serious disfigurement and complications unlikely to resolve without treatment. Various methods for treating infant hemangiomas have been documented, including wait and see policy, laser therapy, drug therapy, sclerotherapy, radiotherapy, surgery and so on, but none of these therapies can be used for all hemangiomas. To obtain the best treatment outcomes, the treatment protocol should be individualized and comprehensive as well as sequential. Based on published literature and clinical experiences, we established a treatment guideline in order to provide criteria for the management of head and neck hemangiomas. This protocol will be renewed and updated to include and reflect any cutting-edge medical knowledge, and provide the newest treatment modalities which will benefit our patients. PMID:24260591

    2000-01-01

    Background: There is a small body of research on improving the clarity of abstracts in general that is relevant to improving the clarity of abstracts of systematic reviews. Objectives: To summarize this earlier research and indicate its implications for writing the abstracts of systematic reviews. Method: Literature review with commentary on three main features affecting the clarity of abstracts: their language, structure, and typographical presentation. Conclusions: The abstracts of systematic reviews should be easier to read than the abstracts of medical research articles, as they are targeted at a wider audience. The aims, methods, results, and conclusions of systematic reviews need to be presented in a consistent way to help search and retrieval. The typographic detailing of the abstracts (type-sizes, spacing, and weights) should be planned to help, rather than confuse, the reader. PMID:11055300

  1. Tire Crumb Research Study Literature Review / Gap ...

    EPA Pesticide Factsheets

    In order to more fully understand data gaps in human exposure and toxicity to tire crumb materials, ATSDR, CPSC and EPA undertook a collaborative effort in the form of a scientific literature review and subsequent gaps analysis. The first objective of the Literature Review and Gap Analysis (LRGA) collaboration was to identify the existing body of literature related specifically to human exposure to tire crumb materials through the use of synthetic turf athletic fields and playgrounds. The second objective was to characterize and summarize the relevant data from the scientific literature. The final objective was to review the summary information and identify data gaps to build on the current understanding of the state-of-the-science and inform the development of specific research efforts that would be most impactful in the near-term. Because of the need for additional information, the U.S. Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (ATSDR), and the U.S. Consumer Product Safety Commission (CPSC) launched a multi-agency action plan to study key environmental human health questions. The Federal Research Action Plan includes numerous activities, including research studies (U.S. EPA, 2016). A key objective of the Action Plan is to identify key knowledge gaps.

    To compare computed tomography (CT) and magnetic resonance imaging (MRI) findings between two histological types of nasal hemangiomas (cavernous hemangioma and capillary or lobular capillary hemangioma). CT (n = 20; six pre-contrast; 20 post-enhancement) and MRI (n = 7) images from 23 patients (16 men and seven women; mean age, 43 years; range, 13-73 years) with a pathologically diagnosed nasal cavity hemangioma (17 capillary and lobular capillary hemangiomas and six cavernous hemangiomas) were reviewed, focusing on lesion location, size, origin, contour, enhancement pattern, attenuation or signal intensity (SI), and bony changes. The 17 capillary and lobular hemangiomas averaged 13 mm (range, 4-37 mm) in size, and most (n = 13) were round. Fourteen capillary hemangiomas had marked or moderate early phase enhancement on CT, which dissipated during the delayed phase. Four capillary hemangiomas on MRI showed marked enhancement. Bony changes were usually not seen on CT or MRI (seen on five cases, 29.4%). Half of the lesions (2/4) had low SI on T1-weighted MRI images and heterogeneously high SI with signal voids on T2-weighted images. The six cavernous hemangiomas were larger than the capillary type (mean, 20.5 mm; range, 10-39 mm) and most had lobulating contours (n = 4), with characteristic enhancement patterns (three centripetal and three multifocal nodular), bony remodeling (n = 4, 66.7%), and mild to moderate heterogeneous enhancement during the early and delayed phases. CT and MRI findings are different between the two histological types of nasal hemangiomas, particularly in the enhancement pattern and size, which can assist in preoperative diagnosis and planning of surgical tumor excision.

    It is the purpose of this article to illuminate the phenomenon of unitary pattern through a review of theoretical literature. Unitary pattern is a phenomenon of significance to the discipline of nursing because it is manifested in and informs all person-environment health experiences. Unitary pattern was illuminated by: addressing the barriers to understanding the phenomenon, presenting a definition of unitary pattern, and exploring Eastern and Western theoretical literature which address unitary pattern in a way that is congruent with the definition presented. This illumination of unitary pattern will expand nursing knowledge and contribute to the discipline of nursing.

    2005-04-01

    To review the body of literature addressing polypharmacy in individuals aged 60 years and older to (a) determine primary care providers' definition of polypharmacy, (b) explore how polypharmacy was assessed in primary care, and (c) seek tested interventions that address polypharmacy. A systematic review of electronic bibliographic databases (e.g. EBSCOHost, InfoTrac, OVID, FirstSearch, and FirstSearch Deluxe) utilizing the search terms "polypharmacy," "polypharmacy and elderly," "polypharmacy and research," and "multiple medications" for the period January 1991 to October 2003 was completed. The search was supplemented with online site searches of relevant journals and review of reference lists of each article. Results of the literature review revealed that polypharmacy continues to be a significant issue and little research has been conducted regarding the methods primary care providers utilize to assess polypharmacy. Also, there is a gap in the literature regarding the interventions implemented by primary care providers to address polypharmacy. The following definition of polypharmacy in clinical practice might be more practical: the use of medications that are not clinically indicated. Selecting appropriate limits for numbers of medications may be counterproductive in populations with multiple comorbidities.

    EPA Pesticide Factsheets

    A literature review was conducted to identify available surface sediment sampling technologies with an ability to collect undisturbed sediments to depths of up to 1 meter below the water sediment interface. This survey was conducted using published literature and references, Environmental Protection Agency reports, professional sources, journal articles, internet web sites, sales brochures, and other sources as identified. For each piece of sampling equipment or sampling tool identified during the literature search, the following information was collected: general description of the equipment or tool, including its size, shape, weight, and composition; manufacturer's name, address, phone number, and email; a picture of the equipment or tool; the general mechanism of operation; sample volume collected; chemical and physical compatibility concerns; labor requirements; cost; and other requirements such as electrical power or specialized training. Sampling methodologies included in this investigation are grab or core types of sampling devices, as these types are most typically used in collecting surface sediments. In this review, 40 samplers were identified that included 13 grab samplers and 27 core samplers. Grab samplers included in the review are the Ponar, Birge-Ekman, Van Veen, Peterson, Mud Snapper, Scoopfish, Shipek, Smith-McIntyre, and others. Core samplers included in the review are the piston, splitcore, box, Vibracore, Mackereth, Ballchek, Craib, Gomex,

  7. Defining professional nursing accountability: a literature review.

    Krautscheid, Lorretta C

    2014-01-01

    Professional nursing accountability is described by both professional nursing organizations and nursing education credentialing agencies as a core aspect that underpins professional nursing practice. Although accountability is foundational to professional practice, a review of the literature revealed no consistent language or definition regarding professional nursing accountability. Instead, the literature itself reveals that professional nursing accountability is challenging to both describe and define. The ambiguity surrounding how to define professional nursing accountability contributes to challenges associated with both teaching and evaluating student nurse accountability within nursing education curricula. This article provides a reliable and comprehensive definition of professional nursing accountability derived from a synthesis of the literature. Recommendations for nursing education practice and recommendations for nursing education research are proposed.

    2012-01-01

    Toothbrushes are commonly used in hospital settings and may harbor potentially harmful microorganisms. A peer-reviewed literature review was conducted to evaluate the cumulative state of knowledge related to toothbrush contamination and its possible role in disease transmission. A systematic review was conducted on adult human subjects through three distinct searches. The review resulted in seven experimental and three descriptive studies which identified multiple concepts related to toothbrush contamination to include contamination, methods for decontamination, storage, design, and environmental factors. The selected studies found that toothbrushes of healthy and oral diseased adults become contaminated with pathogenic bacteria from the dental plaque, design, environment, or a combination of factors. There are no studies that specifically examine toothbrush contamination and the role of environmental factors, toothbrush contamination, and vulnerable populations in the hospital setting (e.g., critically ill adults) and toothbrush use in nursing clinical practice.

    We report the 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) findings of sclerosing angiomatoid nodular transformation (SANT) of the spleen. The patient was a 37-year-old woman with a splenic mass incidentally found on abdominal ultrasound. FDG-PET/CT showed weak FDG accumulation (maximum standardized uptake value = 3.65). An unenhanced CT scan showed a low density and well-circumscribed splenic tumor that demonstrated weak enhancement from the arterial to delayed phase. Although hemangioma or hamartoma of the spleen was preoperatively diagnosed, histopathological examination revealed SANT. Therefore, when a splenic tumor with weak contrast medium enhancement and low FDG accumulation is observed, SANT should be considered as a differential diagnosis. Although CT and magnetic resonance imaging features of SANT have been reported, there are few reports on FDG-PET/CT findings. We report the radiological features of SANT, including FDG-PET/CT, and review the literature on SANT.

    Lipedema is a disorder of adipose tissue that primarily affects females and is often misdiagnosed as obesity or lymphedema. Relatively few studies have defined the precise pathogenesis, epidemiology, and management strategies for this disorder, yet the need to successfully identify this disorder as a unique entity has important implications for proper treatment. In this review, we sought to review and identify information in the existing literature with respect to the epidemiology, pathogenesis, clinical presentation, differential diagnosis, and management strategies for lipedema. The current literature suggests that lipedema appears to be a clinical entity thought to be related to both genetic factors and fat distribution. While distinct from lymphedema and obesity, there are some existing treatments such as complex decongestive physiotherapy, liposuction, and laser-assisted lipolysis. Management of lipedema is complex and distinct from lymphedema. The role of newer randomized controlled studies to further explore the management of this clinical entity remains promising. © The Author(s) 2014.

    This article aims to examine gender stereotypes in relation to men in nursing, discuss gender discrimination cases in nursing, and explore methods used for promoting equal educational opportunities during nursing studies. The literature review was based on related databases, such as CINAHL, Science Direct, MEDLINE, and EBSCO. Legal case studies are included in order to provide a more practical example of those barriers existing for men pursuing nursing, as well as statistical data concerning gender discrimination and male attrition to nursing schools in relation to those barriers. These strengthen the validity of the manuscript. Literature review showed that gender discrimination is still prevalent within nursing profession. Nursing faculty should prepare male nursing students to interact effectively with female clients as well. Role modeling the therapeutic relationship with clients is one strategy that may help male students. In general, the faculty should provide equal learning opportunities to nursing students.

    PubMed

    Kittle, Jolene

    Gangs and gang violence are a concerning cause of preventable injuries and death in the trauma community. The number of gangs and gang members has been on an upward trend since 2003 with an estimated 30,000 gangs in the United States. This includes approximately 850,000 gang members. Trauma centers are in a unique position to participate in the prevention of gang violence. This review compiles current, relevant literature on gangs and gang violence covering the following topics: prevention/intervention, contributing influences, and experiential reflections. The purpose of the literature review is to deepen understanding of gangs and gang violence and potentiate further research in this area in order to help promote successful prevention efforts. Trauma nurses can use this information in developing culturally sensitive, compassionate care and trauma centers will find this useful in the development of injury prevention programs aimed at the reduction of gang and street violence.

    Proprioceptive mechanoreceptors provide neural feedback for position in space and are critical for three-dimensional interaction. Proprioception is decreased with osteoarthritis of the knees, which leads to increased risk of falling. As the prevalence of osteoarthritis increases so does the need for total knee arthroplasty (TKA), and knowing the effect of TKA on proprioception is essential. This article reviews the literature regarding proprioception and its relationship to balance, aging, osteoarthritis, and the effect of TKA on proprioception. Knee arthroplasty involving retention of the cruciate ligaments is also reviewed, as well the evidence of proprioception in the posterior cruciate ligament after TKA.

    Peters anomaly is a rare dramatic finding at birth and can be associated with other systemic malformations. We performed a literature review of multiple case reports and case series to better define the common characteristics and unusual findings associated with Peters anomaly. A representative case is discussed followed by a literature review of multiple case reports and case series. The literature search was conducted for the years 1969 to 2009. Cases and case series were included in the review of published English ophthalmic literature. Cases were excluded if no information was reported on ocular and systemic malformations or if no information was reported on surgical interventions or outcomes. In addition, if cases did not report laterality of the lesion, they were excluded from the review. Fifty-eight cases were found that fit the above criteria, and the relevant cases were reviewed to better characterize the systemic malformations, interventions, and outcomes associated with Peters anomaly reported in the literature. Fifty-eight cases of Peters anomaly were reviewed. Of those cases reporting sex, 56% were men and 44% of cases were women. In terms of laterality, 67.2% of cases were bilateral versus 32.8% of cases that were unilateral. Moreover, bilateral cases of Peters anomaly were associated with a higher rate of systemic malformations (71.8%) versus unilateral Peters anomaly (36.8%). This difference was significant (P < 0.03 by Fischer exact test). In the 15 eyes where results of penetrating keratoplasty were reported, the overall success rate was 53%. However, the success rate was significantly higher in patients with Peters anomaly type I (87.5%), as opposed to those patients with Peters anomaly type II (14.2%) (P < 0.02 by Fischer exact test). The clinical features, epidemiology, genetics, complications, and treatments of Peters anomaly are presented. Cornea specialists who care for pediatric patients should be aware of the common and uncommon

    Objectives The aim of this study was to evaluate the technical and clinical outcomes of using laparoscopic radiofrequency (RF) ablation for treating large subcapsular hepatic hemangiomas. Methods We retrospectively reviewed our sequential experience of treating 124 large subcapsular hepatic hemangiomas in 121 patients with laparoscopic RF ablation. Results The mean diameter of the 124 hemangiomas was 9.1 ± 3.2 cm (5.0–16.0 cm). RF ablation was performed successfully in all patients. There were 55 complications related to the ablation in 26 patients, including 5 of 69 (7.3%) patients with hemangioma <10 cm and 21 of 52 (40.4%) patients with hemangiomas ≥10 cm (P < 0.001). No injuries to abdominal viscera occurred in all the 121 patients. According to the Dindo–Clavien classification, all the complications were minor in 26 patients (Grade I). Out of 124 hepatic hemangiomas, 118 (95.2%) were completely ablated, including 70 of 72 (97.2%) lesions < 10 cm and 48 of 52 (92.3%) lesions ≥ 10 cm (P = 0.236). Conclusion Laparoscopic RF ablation therapy is a safe, feasible and effective procedure for large subcapsular hepatic hemangiomas, even in the hepatic hemangiomas ≥ 10 cm. Its use avoids thermal injury to the abdominal viscera. PMID:26901132

    Wipe sampling is an important technique for the estimation of contaminant deposition in buildings, homes, or outdoor surfaces as a source of possible human exposure. Numerousmethods of wipe sampling exist, and each method has its own specification for the type of wipe, wetting solvent, and determinative step to be used, depending upon the contaminant of concern. The objective of this report is to concisely summarize the findings of a literature review that was conducted to identify the state-of-the-art wipe sampling techniques for a target list of compounds. This report describes the methods used to perform the literature review; a brief review of wipe sampling techniques in general; an analysis of physical and chemical properties of each target analyte; an analysis of wipe sampling techniques for the target analyte list; and asummary of the wipe sampling techniques for the target analyte list, including existing data gaps. In general, no overwhelming consensus can be drawn from the current literature on how to collect a wipe sample for the chemical warfare agents, organophosphate pesticides, and other toxic industrial chemicals of interest to this study. Different methods, media, and wetting solvents have been recommended and used by various groups and different studies. For many of the compounds of interest, no specific wipe sampling methodology has been established for their collection. Before a wipe sampling method (or methods) can be established for the co

    Infantile hemangiomas are well known for their rapid growth during the first 6 to 9 months of life, followed by a spontaneous but slow involution. The standard of care is to treat these lesions at an early age with propranolol to expedite the involution process; however, surgery still remains an active component in the management. Medical treatment with propranolol or natural involution will often result in residual telangiectasias. We evaluated the efficacy of using a diode laser as a treatment for telangiectasias following cervicofacial infantile hemangioma involution. Case series with chart review. Tertiary care hospital and practice specializing in the care of vascular anomalies. Twenty patients, aged 4 months to 11 years (average 2.69 years), underwent treatment with a 532-nm diode laser to treat the residual telangiectasias following hemangioma involution. All procedures were performed in the operating room. To assess the efficacy, we independently evaluated pre- and posttreatment digital photographs and ranked them on a 0- to 4-point scale (0 = no change and 4 = complete response). Adverse reactions were also recorded. The telangiectasias showed considerable improvement following treatment. In more than half of the patients treated, the affected area demonstrated a complete response. No adverse reactions were noted. A 532-nm diode laser effectively treats the remaining telangiectasias following hemangioma involution. Whether used independently or in conjunction with other treatment modalities, the diode laser should be part of the surgical armamentarium when treating infantile hemangiomas. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

    2012-01-01

    Introduction Childbearing depression (CBD) and childhood aggression are serious and international problems that encumber public health. Although maternal depression has received much attention in the literature in the last three decades, clinically it remains under-diagnosed and under-treated, especially during pregnancy. As a result, many mothers and families are left to suffer its long-lasting physical and psychosocial effects. This article's aim is to review the current literature on whether CBD increases the likelihood of childhood aggression in children ages six years and younger. Methods Using keywords, an electronic search was performed using Cumulative Index of Nursing and Allied Health, PsycINFO, and PubMed databases. Search limits included the following: 2000-2010, English, peer-review, human, All Child: 0-18. From more than 2,000 search results, 13 articles were reviewed based on relevance to paper's inquiry and sample size greater than 50. Results In all, the articles agreed that depression in women increases the likelihood of early childhood aggression by causing negative parenting behaviors. However, this finding is tempered by a number of weaknesses in the quality of articles reviewed and by the complexity of the topic. Conclusion More research is needed to determine the etiology and interplay of mediating factors between CBD and childhood aggression. This could inform the study and implementation of effective and early prevention, screening, and treatment measures and programs for maternal depression and childhood aggression. PMID:22739482

    2016-01-01

    The global primary literature on Zika virus (ZIKV) (n = 233 studies and reports, up to March 1, 2016) has been compiled using a scoping review methodology to systematically identify and characterise the literature underpinning this broad topic using methods that are documented, updateable and reproducible. Our results indicate that more than half the primary literature on ZIKV has been published since 2011. The articles mainly covered three topic categories: epidemiology of ZIKV (surveillance and outbreak investigations) 56.6% (132/233), pathogenesis of ZIKV (case symptoms/ outcomes and diagnosis) 38.2% (89/233) and ZIKV studies (molecular characterisation and in vitro evaluation of the virus) 18.5% (43/233). There has been little reported in the primary literature on ZIKV vectors (12/233), surveillance for ZIKV (13/233), diagnostic tests (12/233) and transmission (10/233). Three papers reported on ZIKV prevention/control strategies, one investigated knowledge and attitudes of health professionals and two vector mapping studies were reported. The majority of studies used observational study designs, 89.7% (209/233), of which 62/233 were case studies or case series, while fewer (24/233) used experimental study designs. Several knowledge gaps were identified by this review with respect to ZIKV epidemiology, the importance of potential non-human primates and other hosts in the transmission cycle, the burden of disease in humans, and complications related to human infection with ZIKV. Historically there has been little research on ZIKV; however, given its current spread through Australasia and the Americas, research resources are now being allocated to close many of the knowledge gaps identified in this scoping review. Future updates of this project will probably demonstrate enhanced evidence and understanding of ZIKV and its impact on public health. PMID:27244249

The costs of the disease's management remain large for individuals and society. While literature on the economic impact of schizophrenia is abundant, few studies have focused on its humanistic burden. This does not only concern patients, but also caregivers, relatives, neighbours and others in a patient's daily life. This burden appears through several dimensions, including treatment side effects and the impact on caregivers and features of the patient's environment. The aim of this review is to consider, compile and describe the humanistic burden of schizophrenia as documented in the literature. We conducted a literature review assessing the worldwide disease burden of schizophrenia, taking into account all humanistic burden topics. The search considered several databases, including Embase, Medline, Cochrane Library, The German Institute of Medical Documentation and Information (DIMDI) and the ISPOR conference websites. The search identified 200 literature reviews, covering several dimensions of humanistic burden and documenting many issues. Main findings included the high death rates that may be explained by long-lasting negative health habits, disease- and treatment-related metabolic disorders, and consequent increased frequencies of cardiovascular diseases. Co-existing depression was found to have adverse consequence on the course of schizophrenia progression, morbidity and mortality. Cognitive impairment also adds to the burden of schizophrenia. Social impairment is worsened by underestimated stigmatisation and lack of corresponding awareness within the professional and social spheres. Finally, caregiver burden was found to be considerable. Humanistic burden among patients with schizophrenia is substantial potentially impacted by co-morbid depressive symptoms

    The global primary literature on Zika virus (ZIKV) (n = 233 studies and reports, up to March 1, 2016) has been compiled using a scoping review methodology to systematically identify and characterise the literature underpinning this broad topic using methods that are documented, updateable and reproducible. Our results indicate that more than half the primary literature on ZIKV has been published since 2011. The articles mainly covered three topic categories: epidemiology of ZIKV (surveillance and outbreak investigations) 56.6% (132/233), pathogenesis of ZIKV (case symptoms/ outcomes and diagnosis) 38.2% (89/233) and ZIKV studies (molecular characterisation and in vitro evaluation of the virus) 18.5% (43/233). There has been little reported in the primary literature on ZIKV vectors (12/233), surveillance for ZIKV (13/233), diagnostic tests (12/233) and transmission (10/233). Three papers reported on ZIKV prevention/control strategies, one investigated knowledge and attitudes of health professionals and two vector mapping studies were reported. The majority of studies used observational study designs, 89.7% (209/233), of which 62/233 were case studies or case series, while fewer (24/233) used experimental study designs. Several knowledge gaps were identified by this review with respect to ZIKV epidemiology, the importance of potential non-human primates and other hosts in the transmission cycle, the burden of disease in humans, and complications related to human infection with ZIKV. Historically there has been little research on ZIKV; however, given its current spread through Australasia and the Americas, research resources are now being allocated to close many of the knowledge gaps identified in this scoping review. Future updates of this project will probably demonstrate enhanced evidence and understanding of ZIKV and its impact on public health.

    There is evidence that acupuncture may relieve pain. To assess the evidence about the effectiveness of acupuncture to relieve postoperative pain. A systematic review of the literature selecting controlled clinical trials and systematic reviews comparing acupuncture with standard pain management. The value and quality of reports were evaluated using Jadad scale and STRICTA protocol. Pain intensity and analgesic consumption were the primary endpoints sought. Five controlled trials and two systematic reviews were selected. A meta-analysis was not feasible due to the heterogeneity of studies. In the postoperative period of tonsillectomy, acupuncture reduced pain by 36 and 22% at 20 minutes and two hours, respectively. In knee replacement, acupuncture reduced pain by 2% and analgesic consumption by 42%. In the postoperative period of dental interventions, acupuncture reduced pain by 24% at two hours. Acupuncture may be useful to manage postoperative pain, but more controlled studies are required.

    The literature related to people with borderline intellectual functioning (BIF) was systematically reviewed in order to summarize the present knowledge. Database searches yielded 1,726 citations, and 49 studies were included in the review. People with BIF face a variety of hardships in life, including neurocognitive, social, and mental health problems. When adults with BIF were compared with the general population, they held lower-skilled jobs and earned less money. Although some risk factors (e.g., low birth weight) and preventive factors (e.g., education) were reported, they were not specific to BIF. The review finds that, despite the obvious everyday problems, BIF is almost invisible in the field of research. More research, societal discussion, and flexible support systems are needed.

    2013-12-01

    Meralgia Paresthetica (MP) is a nerve entrapment which may cause pain, paresthesias, and sensory loss within the distribution of the lateral cutaneous nerve of the thigh. When the differential diagnosis of lateral or anterolateral thigh pain is inconclusive, MP should be considered as a potential source. MP produces similar signs and symptoms as those associated with more common diagnoses such as lumbar spine pathology. This clinical commentary will review the most relevant literature on MP with an emphasis on recognition and management of this condition. The authors reviewed the most relevant published literature on MP from 1970 to 2013 located using the databases PubMed, CINAHL, and Proquest. MP still remains a diagnostic challenge since it can mimic other common diagnoses. Understanding the current literature surrounding the diagnosis and treatment of MP is essential for clinicians practicing in the outpatient environment. The consensus on the most effective non-surgical and surgical interventions is still limited, as is the research on physical therapy interventions for this condition. Perhaps the lack of research and global consensus represents a knowledge deficit that makes MP a challenge to diagnose and successfully treat. Future collaborative studies are needed to improve the clinical diagnostics and understanding of interventions for this pathology. 5.

Description of Topic with Related Evidence: The authors reviewed the most relevant published literature on MP from 1970 to 2013 located using the databases PubMed, CINAHL, and Proquest. Discussion/Relation to Clinical Practice: MP still remains a diagnostic challenge since it can mimic other common diagnoses. Understanding the current literature surrounding the diagnosis and treatment of MP is essential for clinicians practicing in the outpatient environment. The consensus on the most effective non‐surgical and surgical interventions is still limited, as is the research on physical therapy interventions for this condition. Perhaps the lack of research and global consensus represents a knowledge deficit that makes MP a challenge to diagnose and successfully treat. Future collaborative studies are needed to improve the clinical diagnostics and understanding of interventions for this pathology. Level of Evidence: 5 PMID:24377074

    Studies have revealed possible link between periodontitis and different systemic diseases. There is need to review this interesting subject. The aims are: to provide a comprehensive literature that can easily be consulted, on the subject; to draw the attention of health practitioners to the impact of oral health on the general well-being; and to emphasize the need for a deeper interaction between medical and dental training. The Medline database was searched for relevant literature by combining each of the following terms, “oral health,” “oral infection,” “periodontitis,” with “systemic diseases.” Manual library search and review of bibliographies of published literature were also conducted. Periodontitis is a constant potential source of infection and has been considered as a separate risk factor for some cardiovascular, respiratory, endocrine, musculoskeletal, and reproductive system related abnormalities. Oral health impacts on the general well-being, and if comprehensive health care is ever to be achieved, oral health should not be seen as a separate, distant, and less important area of health, which is totally unrelated to lifespan and its quality.

    The term “resilience” is ubiquitous in technical literature; it appears in numerous forms, such as resilience, resiliency, or resilient, and each use may have a different definition depending on the interpretation of the writer. This creates difficulties in understanding what is meant by ‘resilience’ in any given use case, especially in discussions of interdisciplinary research. To better understand this problem, this research constructs a preliminary integrative literature review to map different definitions, applications and calculation methods of resilience invoked within critical infrastructure applications. The preliminary review uses a State-of-the-Art Matrix (SAM) analysis to characterize differences in definition across disciplines and between regions. Qualifying the various usages of resilience will produce a greater precision in the literature and a deeper insight into types of data required for its evaluation, particularly with respect to critical infrastructure calculations and how such data may be analyzed. Results from this SAM analysis will create a framework of key concepts as part of the most common applications for “resilient critical infrastructure” modeling.

    The discovery of beta-adrenergic blocker effects on infantile hemangiomas has affected the choice of treatment in recent years. Oral propranolol is effective in treating infantile hemangiomas, but the risk of systemic side effects remains a concern. Data from literature review reported positive clinical outcomes with no major adverse effects observed in children using topical beta-blocker such as timolol maleate. Topical application of timolol eye drop has been mentioned in few studies, most of which reported that the solution cannot stay on the site of application due to its fluidity. Adding hydroxyethyl cellulose into a timolol solution increased its viscosity by forming a hydrogel and thus changed the rheology property. The compounded timolol gel exhibited thixotropy property allowing better and longer contact at sites of application. Experimental data from literature review showed desirable characteristics and measurable flux of timolol across human stratum corneum. Gel dosage form allows easy and precise application and maximizes timolol's therapeutic efficacy at the sites of application. Copyright© by International Journal of Pharmaceutical Compounding, Inc.

    In general, veterinary dermatologists do not have extensive clinical experience of nonhuman primate (NHP) dermatoses. The bulk of the published literature does not provide an organized evidence-based approach to the NHP dermatologic case. The veterinary dermatologist is left to extract information from both human and veterinary dermatology, an approach that can be problematic as it forces the clinician to make diagnostic and therapeutic decisions based on two very disparate bodies of literature. A more cohesive approach to NHP dermatology – without relying on assumptions that NHP pathology most commonly behaves similarly to other veterinary and human disease – is required. This review of the dermatology of NHP species includes discussions of primary dermatoses, as well as diseases where dermatologic signs represent a significant secondary component, provides a first step towards encouraging the veterinary community to study and report the dermatologic diseases of nonhuman primates.

    Aims: Through the review of relevant literature this study illuminates the concepts of social marketing and breastfeeding. It specifically discusses the positioning of the link between social marketing and breastfeeding within different fields of study and develops a theoretical framework that tries to bridge the gap between those disciplines. Method: Various electronic databases were used and through systematic selection 11 scientific articles were identified that this literature review is based on. Results: The review indicates that the relationship between social marketing and breastfeeding is complex. There are indications that this relationship is being investigated within three distinct fields of research: psychology/education, public health and marketing. Depending on the research field the emphasis is put on either breastfeeding or social marketing as well as on the other concepts that were discovered to be of importance within this relationship. Namely, group and individual demography as well as behaviour were revealed to be important elements of the link between social marketing and breastfeeding. Conclusions: Based on the results this study concludes that a more multidimensional view on the relationship between the concepts under study is needed since the focus of previous studies is very one-sided and limited to just one element when all elements should be integrated equally.

    The present literature review on functional assessment in physiotherapy was carried out for the following reasons: 1) to identify the functional instruments used in the field of physiotherapy that were supported by published evidence of their psychometric qualities; 2) to investigate how these instruments relate to the International Classification of Functioning, Disability and Health (ICF); and 3) to investigate the use of functional instruments in the financing of physiotherapy. A search of Medline from 1990 to December 2005, in the domains of functional evaluation, psychometric qualities, functional classification, and health policy in relation to physiotherapy resulted in a list of 1,567 studies. Two reviewers examined the resulting references on the basis of their title and abstract, in order to select the studies that presented data on the psychometric qualities of functional evaluation tests, leading to a final selection of 44 such studies. A selection of functional tests was identified in four major diagnostic groups treated in community physiotherapy: musculoskeletal disorders (including lower back pain), stroke, the elderly, and traumatic brain injuries. The functional tests authors identified essentially cover the body and activities dimension of the ICF. The selected tests could be used as a basis for the standardisation of functional evaluation of the major diagnostic groups treated in community physiotherapy. This means that standards are available for reporting and following the evolution of patients both longitudinally and transversally. Nevertheless, in the current literature review no attempt at using functional outcomes as a rationale for financing physiotherapy could be found to date.

    In previous decades, manufacturers faced a lot of challenges because of globalization and high competition in markets. These problems arise from shortening product life cycle, rapid variation in demand of products, and also rapid changes in manufcaturing technologies. Nowadays most manufacturing companies expend considerable attention for improving flexibility and responsiveness in order to overcome these kinds of problems and also meet customer's needs. By considering the trend toward the shorter product life cycle, the manufacturing environment is towards manufacturing a wide variety of parts in small batches [1]. One of the major techniques which are applied for improving manufacturing competitiveness is Cellular Manufacturing System (CMS). CMS is type of manufacturing system which tries to combine flexibility of job shop and also productivity of flow shop. In addition, Dynamic cellular manufacturing system which considers different time periods for the manufacturing system becomes an important topic and attracts a lot of attention to itself. Therefore, this paper made attempt to have a brief review on this issue and focused on all published paper on this subject. Although, this topic gains a lot of attention to itself during these years, none of previous researchers focused on reviewing the literature of that which can be helpful and useful for other researchers who intend to do the research on this topic. Therefore, this paper is the first study which has focused and reviewed the literature of dynamic cellular manufacturing system.

    Workplace safety has been historically neglected by organizations in order to enhance profitability. Over the past 30 years, safety concerns and attention to safety have increased due to a series of disastrous events occurring across many different industries (e.g., Chernobyl, Upper Big-Branch Mine, Davis-Besse etc.). Many organizations have focused on promoting a healthy safety culture as a way to understand past incidents, and to prevent future disasters. There is an extensive academic literature devoted to safety culture, and the Department of Energy has also published a significant number of documents related to safety culture. The purpose of the current endeavor was to conduct a review of the safety culture literature in order to understand definitions, methodologies, models, and successful interventions for improving safety culture. After reviewing the literature, we observed four emerging themes. First, it was apparent that although safety culture is a valuable construct, it has some inherent weaknesses. For example, there is no common definition of safety culture and no standard way for assessing the construct. Second, it is apparent that researchers know how to measure particular components of safety culture, with specific focus on individual and organizational factors. Such existing methodologies can be leveraged for future assessments. Third, based on the published literature, the relationship between safety culture and performance is tenuous at best. There are few empirical studies that examine the relationship between safety culture and safety performance metrics. Further, most of these studies do not include a description of the implementation of interventions to improve safety culture, or do not measure the effect of these interventions on safety culture or performance. Fourth, safety culture is best viewed as a dynamic, multi-faceted overall system composed of individual, engineered and organizational models. By addressing all three components of

    Resident doctors contribute significantly to the quality of undergraduate medical training and it is assumed that by participating in the process, they also improve their own professional competency. We decided to investigate whether there is evidence to support this assumption. Our hypothesis, the physician-as-teacher rule, stated that "A skilled teacher has an increased likelihood of becoming a competent clinician, than a skilled clinician has of becoming a competent teacher". We conducted a literature review to search for evidence to confirm or refute this assumption. Twenty-four articles written after 1990 were identified as relevant from 132 references we generated by searching Medline. The identified articles were qualitatively reviewed to identify key research conclusions and/or main discussion points. The findings from the review were collated and discussed. None of the studies showed specific evidence of how teaching results in improved professional competence. However, there was evidence that teaching ability correlated positively with the perception of clinical competency. There was also need for improved supervision and training programmes for residents in teaching skills. The review provided evidence that teaching influenced the perceived professional competency of physicians positively. Physicians who were perceived as competent were those who taught effectively, and who had a basic understanding of teaching and learning. The review shows that training in teaching is essential for physicians, and that further research is still needed to demonstrate the effect of good teaching on professional competency.

    The present study aimed to update the literature review on the prevalence of fibromyalgia published in 2006. A bibliographical survey was carried out from 2005 to 2014 in the MEDLINE, Web of Science, Embase, LILACS and SciELO databases and 3274 records were identified. Five researchers selected the studies, following the inclusion criteria: studies that obtained the prevalence of fibromyalgia. Fibromyalgia studies in associated diseases were excluded. When screening by title and abstract, 2073 irrelevant articles were excluded. The full texts of 210 articles were evaluated for eligibility and this review included 39 studies, described in 41 articles. The selected studies were grouped into four categories: (A) prevalence of fibromyalgia in the general population; (B) prevalence of fibromyalgia in women; (C) prevalence of fibromyalgia in rural and urban areas; (D) prevalence of fibromyalgia in special populations. The literature shows values of fibromyalgia prevalence in the general population between 0.2 and 6.6%, in women between 2.4 and 6.8%, in urban areas between 0.7 and 11.4%, in rural areas between 0.1 and 5.2%, and in special populations values between 0.6 and 15%. This literature review update shows a significant increase in fibromyalgia prevalence studies in the world. The new 2010 American College of Rheumatology criteria have not been widely used yet and the COPCORD (Community-oriented program for control of Rheumatic Diseases) methodology has increased the quality of studies on the prevalence of rheumatic diseases in general.

    Cold urticaria is one of the five most common causes of chronic urticaria and is grouped as a physical urticaria. It can occur after exposure to cold, either through solid objects, air or liquids. Patients may have symptoms of urticaria, angioedema, respiratory distress and even anaphylaxis when the skin is exposed to a cold environment, such as handling refrigerated objects, swimming in cold water or entering an air-conditioned room. Five cases of cold urticaria are presented, followed by a brief literature review.

    Pseudocirrhosis describes morphological changes of the liver that closely mimic cirrhosis, without the typical histopathological changes seen in cirrhosis. It most commonly occurs in patients with metastatic breast cancer, although it has been reported in other malignancies as well. Like in cirrhosis, portal hypertension is often seen in patients with pseudocirrhosis. Pseudocirrhosis is a rare but important complication of metastatic cancer. In this case series and literature review, we describe 6 patients with hormone-receptor-positive metastatic breast cancer. We report the significant morbidity associated with pseudocirrhosis in the course of treatment in patients with metastatic breast cancer. PMID:27721722

    Obesity has currently reached epidemic proportions, both in Chile and in the world. This condition is associated to a variety of maternal complications in all stages of the vital cycle and during pregnancy. Medical treatment has not proved successful thus resulting in an increase in bariatric surgery in recent years, even when it is not first line treatment. This literature review aims to report updated results of surgical treatment for obesity before and during pregnancy with respect to fertility, gestational diabetes, pre-eclampsia and pregnancy-induced hypertension. It also looks into the possible effects of surgery on fetal development, and its relation to premature delivery, fetal macrosomy, low birth weight and neural tube defects, as well as effects on maternal and fetal outcomes, mainly in nutrition. Lastly, we suggest some recommendations that arise from this review on the role of contraception, nutrition and time between surgery and pregnancy.

    The Montessori method was initially applied to children, but now it has also been applied to people with dementia. The purpose of this study is to systematically review the research on the effectiveness of this method using Medical Literature Analysis and Retrieval System Online (Medline) with the keywords dementia and Montessori method. We selected lo studies, in which there were significant improvements in participation and constructive engagement, and reduction of negative affects and passive engagement. Nevertheless, systematic reviews about this non-pharmacological intervention in dementia rate this method as weak in terms of effectiveness. This apparent discrepancy can be explained because the Montessori method may have, in fact, a small influence on dimensions such as behavioral problems, or because there is no research about this method with high levels of control, such as the presence of several control groups or a double-blind study.

    The purpose of the present article was to assess the available literature concerning pain and autism. First, authors summarized the published articles on pain reactivity in people with autism. Second, the hypotheses envisaged to explain the presence of expressive particularities in people with autism spectrum disorders were reviewed; these included endogenous opioid excess theory, sensorial abnormalities and sociocommunicative deficit. Finally, the present review dealt with the tools available to assess and manage pain in people with autism. In conclusion, the authors revealed the need for more research to obtain more consensual data and provided some recommendations in this domain that were under exploited by the scientific community. From a clinical point of view, more knowledge about pain in people with autism should enable the development of specific assessment tools and, consequently, better pain management in daily care.

    Recently, several in vitro and in vivo studies demonstrated promising results about the use of photodynamic therapy during root canal system disinfection. However, there is no consensus on a standard protocol for its incorporation during root canal treatment. The purpose of this study was to summarize the results of research on photodynamic therapy in endodontics published in peer-reviewed journals. A review of pertinent literature was conducted using the PubMed database, and data obtained were categorized into sections in terms of relevant topics. Studies conducted in recent years highlighted the antimicrobial potential of photodynamic therapy in endodontics. However, most of these studies were not able to confirm a significant improvement in root canal disinfection for photodynamic therapy as a substitute for current disinfection methods. Its indication as an excellent adjunct to conventional endodontic therapy is well documented, however. Data suggest the need for protocol adjustments or new photosensitizer formulations to enhance photodynamic therapy predictability in endodontics.

  17. Radiography Students' Learning: A Literature Review.

    2016-01-01

    To describe research methodology and findings concerning radiography students' learning. Health sciences databases were searched to perform a traditional narrative literature review. Thirty-five peer-reviewed articles published between 2000 and 2014 were analyzed using thematic analysis. Specific methods of learning were found to be of the most interest. The studies focused primarily on the use and usability of a method or the students' general experiences of it. The most commonly studied methods were e-learning and interprofessional learning, which students perceived as positive methods for theoretical studies and clinical training. Students' learning regarding research was the focus of only one article reporting a wide variety of students' research interests. Most studies reported quantitative research gathered from questionnaires and surveys. Additional research, especially from a qualitative point of view, is needed to deepen the evidence-based knowledge of radiography student learning.

    Research on the transgender population is often limited to their medical care, and in particular to their mental well-being. The social and family environment in which a social gender role transition takes place is often overlooked. Although research is limited, this article reviews the existing literature on the family aspect of a gender transition. Articles regarding three different aspects were selected for this review: first, the issue of parenthood during transition and the experiences of children with a transgender parent, second, the experiences of partners and ex-partners of transgender individuals, and third, the experiences of parents with a gender variant child. Articles were restricted to those with a focus on family members and situations during transition. For all three contexts, several mediating factors, both individual and social, were distinguished. Various challenges for future research were identified.

    2011-02-01

    The aim of this review is to describe nurses' work motivation from the perspective of staff nurses. This information would be useful for the development of motivation strategies and further research into nurses' work motivation. A thorough review of the research literature. The literature search was performed using four databases: CINAHL, PubMed, PsychINFO, and SocINDEX. Only studies that met the following criteria were selected for review: (1) were published between 1990 and 2009, (2) were written in English, (3) dealt with work motivation, (4) concerned working staff nurses, (5) involved empirical research, (6) clearly and explicitly provided the research results about the factors affecting nurses' work motivation. Altogether 24 studies met these criteria and were included in this review. Inductive content analysis was carried out to analyse and categorise the data. Nursing research has neither clear understanding nor consensus about the concept of work motivation; nor has a universal definition been adopted. Despite limited empirical evidence it may be concluded that staff nurses appear to be motivated. Five categories of factors affecting their work motivation were identified: (1) work-place characteristics, (2) working conditions, (3) personal characteristics, (4) individual priorities, and (5) internal psychological states. Further research is needed to gain a more comprehensive insight into nurses' work motivation and the factors affecting it. This can be achieved by defining the concept of work motivation as precisely as possible, working out a pertinent research methodology, and subsequently developing and testing a theoretical model of nurses' work motivation.

  1. The meaning of spirituality: a literature review.

    PubMed

    Dyson, J; Cobb, M; Forman, D

    1997-12-01

    This paper presents a literature review in relation to the meaning of spirituality. It is proposed that meeting the spiritual needs of patients is a fundamental part of providing holistic nursing care, but that the assessment and meeting of those needs is impeded by inadequate definitions and conceptual frameworks. It should not be assumed that spirituality is either synonymous, or coterminous, with religion, and it is suggested that to adopt this restrictive view is unhelpful in the provision of individualized care. Reflection on the literature reveals that the self, others and 'God' provide the key elements within a definition of spirituality, and that other emerging themes namely meaning, hope, relatedness/connectedness, beliefs/belief systems and expressions of spirituality, can be articulated in the context of those three key elements. In particular, it is proposed that the nature of 'God' may take many forms and, essentially, is whatever an individual takes to be of highest value in his/her life. It is suggested that the themes emerging from the literature can be utilized as a framework to give practitioners and researchers a direction for future exploration of the concept of spirituality.

    To evaluate cases diagnosed as "oral hemangiomas" based on the immunohistochemical expression of human glucose transporter protein (GLUT-1) and on histopathological features, and to investigate whether the classification proposed by the ISSVA was used correctly to classify these lesions. All cases stored in the archives of an Oral Pathology Service and diagnosed as "oral hemangiomas" were reviewed. Seventy-seven cases were analyzed regarding the expression of GLUT-1. GLUT-1(+) specimens were classified as true infantile hemangioma (IH) and GLUT-1(-) specimens were reclassified based on their histopathological features. The nomenclature of these lesions was evaluated and some cases were reclassified. Only 26 (33.8%) of the specimens were indeed IHs. Among the GLUT-1(-) specimens, 20 (26.0%) were reclassified as pyogenic granulomas (PGs) and 31 (40.2%) as vascular malformations. Considering the previously applied nomenclature, only 47.5% of the cases initially diagnosed as "hemangiomas" were IHs. In the group of "capillary hemangiomas", most cases (56.2%) were PGs. Among the three "cellular hemangiomas", two were PGs and one was IH. Most (88.8%) "cavernous hemangiomas" were vascular malformations. Careful and parameterized review of cases of vascular anomalies is necessary using auxiliary tools such as GLUT-1, since the exclusive use of histopathological findings might be insufficient to differentiate some anomalies. Accurate clinical examination and the use of biomarkers such as GLUT-1 are essential for the diagnosis. Copyright © 2017. Published by Elsevier Inc.

  3. Imagery in Dance: A Literature Review.

    Pavlik, Katherine; Nordin-Bates, Sanna

    2016-01-01

    Dance imagery is a consciously created mental representation of an experience, either real or imaginary, that may affect the dancer and her or his movement. In this study, imagery research in dance was reviewed in order to: 1. describe the themes and ideas that the current literature has attempted to illuminate and 2. discover the extent to which this literature fits the Revised Applied Model of Deliberate Imagery Use. A systematic search was performed, and 43 articles from 24 journals were found to fit the inclusion criteria. The articles were reviewed, analyzed, and categorized. The findings from the articles were then reported using the Revised Applied Model as a framework. Detailed descriptions of Who, What, When and Where, Why, How, and Imagery Ability were provided, along with comparisons to the field of sports imagery. Limitations within the field, such as the use of non-dance-specific and study-specific measurements, make comparisons and clear conclusions difficult to formulate. Future research can address these problems through the creation of dance-specific measurements, higher participant rates, and consistent methodologies between studies.

    Statement of problem: Evidence is limited on the efficacy of zirconia-based fixed dental prostheses. Objective: To carry out a literature review of the behavior of zirconium oxide dental restorations. Material and Methods: This literature review searched the Pubmed, Scopus, Medline and Cochrane Library databases using key search words “zirconium oxide,” “zirconia,” “non-metal restorations,” “ceramic oxides,” “veneering ceramic,” “zirconia-based fixed dental prostheses”. Both in vivo and in vitro studies into zirconia-based prosthodontic restoration behavior were included. Results: Clinical studies have revealed a high rate of fracture for porcelain-veneered zirconia-based restorations that varies between 6% and 15% over a 3- to 5-year period, while for ceramo-metallic restorations the fracture rate ranges between 4 and 10% over ten years. These results provoke uncertainty as to the long-term prognosis for this material in the oral medium. The cause of veneering porcelain fractures is unknown but hypothetically they could be associated with bond failure between the veneer material and the zirconia sub-structure. Key words:Veneering ceramic, zirconia-based ceramic restoration, crown, zirconia, tooth-supported fixed prosthesis. PMID:24596638

  5. Neonatal testicular torsion: a systematic literature review.

    2011-10-01

    Neonatal testicular torsion (NTT) is rare and reported salvage rates vary widely both in their cited frequency and plausibility. The timing and necessity of surgery is controversial with different centers arguing for the conservative management of all cases while others argue for prompt exploration for all. Confusion also reigns over the need to fix the contralateral testis. In order to clarify the issue the authors reviewed the literature and found 18 case series of NTT, containing 268 operated cases suitable for analysis. This paper reviews the literature on NTT specifically regarding salvage rates and timing/necessity of surgery. Its primary aim is to produce an overall salvage rate in the operated group. Overall salvage rate was 8.96%, 24 testes. When operation is specified as an emergency, salvage may be as high as 21.7%. While salvage of a testis torted at birth is rare, it is reported. Early asynchronous torsion is also rare but reported. Worryingly, bilateral torsion can present with unilateral signs.Given these findings, we would suggest early surgery with fixation of the contralateral side.

  6. Emotional outcome after intensive care: literature review.

    2008-10-01

    This paper is a report of a literature review to identify (a) the prevalence of emotional and psychological problems after intensive care, (b) associated factors and (c) interventions that might improve this aspect of recovery. Being a patient in intensive care has been linked to both short- and long-term emotional and psychological consequences. The literature search was conducted during 2006. Relevant journals and databases were searched, i.e. Medline and CINAHL, between the years 1995 and 2006. The search terms were 'anxiety', 'depression', posttraumatic stress', 'posttraumatic stress disorder' and 'intensive care'. Fifteen papers were reviewed representing research studies of anxiety, depression and posttraumatic stress, and seven that represented intensive care follow-up clinics and patient diaries. Being in intensive care can result in significant emotional and psychological problems for a number of patients. For the majority of patients, symptoms of distress will decrease over time but for a number these will endure for some years. Current evidence indicates that emotional problems after intensive care are related to both subjective and objective indicators of a patient's intensive care experience. Evidence suggests some benefit in an early rehabilitation programme, daily sedation withdrawal and the use of patient diaries. However, additional research is required to support such findings. Our understanding of the consequences of intensive care is improving. Psychological care for intensive care patients has lagged behind care for physical problems. We now need to focus on developing and evaluating appropriate interventions to improve psychological outcome in this patient group.

  7. A literature review of nursing turnover costs.

    2013-04-01

    To report the findings of a literature review of studies examining nursing staff turnover costs published between 1990 and 2010. Nurse turnover is a global concern that is both costly for health-care organizations and, in the context of the work environment, affects quality and safety. We reviewed past literature and describe the conceptualization of nurse turnover, evaluate the methodologies and calculation of costs, identify the reported range of turnover costs and provide suggestions for future study. We report inconsistencies in past studies in terms of the conceptualization and measurement of nurse turnover and turnover rates, the methodologies for gathering data and the data sources used, the approaches for calculating turnover costs and the resulting nursing staff turnover costs estimated. Past studies reached different conclusions about nurse turnover. We still need to explore the actual costs and benefits of nurse turnover and retention. This study should be helpful for nurse executives as they build a business case to address nurse turnover in their organizations, and for policy-makers as they develop policies about turnover. © 2012 Blackwell Publishing Ltd.

    This paper reviews the literature on reference pricing (RP) in pharmaceutical markets. The RP strategy for cost containment of expenditure on drugs is analyzed as part of the procurement mechanism. We review the existing literature and the state-of-the-art regarding RP by focusing on its economic effects. In particular, we consider: (1) the institutional context and problem-related factors which appear to underline the need to implement an RP strategy; i.e. its nature, characteristics and the sort of health care problems commonly addressed; (2) how RP operates in practice; that is, how third party-payers (the insurers/buyers) have established the RP systems existing on the international scene (i.e. information methods, monitoring procedures and legislative provisions); (3) the range of effects resulting from particular RP strategies (including effects on choice of appropriate pharmaceuticals, insurer savings, total drug expenditures, prices of referenced and non-referenced products and dynamic efficiency; (4) the market failures which an RP policy is supposed to address and the main advantages and drawbacks which emerge from an analysis of its effects. Results suggest that RP systems achieve better their postulated goals (1) if cost inflation in pharmaceuticals is due to high prices rather than to the excess of prescription rates, (2) when the larger is the existing difference in prices among equivalent drugs, and (3) more important is the actual market for generics.

  9. The "good death": An integrative literature review.

    2016-12-01

    The "good death" is a dynamic concept and has evolved over time to become a "revivalist" good death: a planned, peaceful, and dignified death, at home, surrounded by family members. As the "good death" continues to evolve, the key questions are: How do cultural perceptions of death and dying change? What are the forces that shape Western attitudes and beliefs around death and dying? And how does the "good death" discourse frame the dying experience in contemporary society? The purpose of this manuscript is to describe the underlying discourse in the literature on the "good death" in Western societies. An integrative literature review of data from experimental and nonexperimental sources in PubMed, CINAHL, PsychINFO, and SocINDEX of 39 articles from 1992 to 2014. Four main themes emerged from reviewing 39 articles on the "good death": (1) the "good death" as control, (2) the wrong "good death," (3) the threatened "good death," and (4) the denial of dying. Evolving in response to prominent social attitudes and values, the contemporary "good death" is a powerful, constraining discourse that limits spontaneity and encourages one way to die. Social, political, and demographic changes now threaten the stability of the "good death"; dying is framed as an increasingly negative or even unnecessary process, thus marginalizing the positive aspects of dying and rendering dying absent, invisible.

    There is a lack of agreement regarding the types of lesions and clinical conditions that should be included in the term "geographic atrophy." Varied and conflicting views prevail throughout the literature and are currently used by retinal experts and other health care professionals. We reviewed the nominal definition of the term "geographic atrophy" and conducted a search of the ophthalmologic literature focusing on preceding terminologies and the first citations of the term "geographic atrophy" secondary to age-related macular degeneration. According to the nominal definition, the term "geography" stands for a detailed description of the surface features of a specific region, indicating its relative position. However, it does not necessarily imply that the borders of the region must be sharply demarcated or related to any anatomical structures. The term "geographical areas of atrophy" was initially cited in the 1960s in the ophthalmologic literature in the context of uveitic eye disease and shortly thereafter also for the description of variants of "senile macular degeneration." However, no direct explanation could be found in the literature as to why the terms "geographical" and "geographic" were chosen. Presumably the terms were used as the atrophic regions resembled the map of a continent or well-defined country borders on thematic geographical maps. With the evolution of the terminology, the commonly used adjunct "of the retinal pigment epithelium" was frequently omitted and solely the term "geographic atrophy" prevailed for the nonexudative late-stage of age-related macular degeneration itself. Along with the quantification of atrophic areas, based on different imaging modalities and the use of both manual and semiautomated approaches, various and inconsistent definitions for the minimal lesion diameter or size of atrophic lesions have also emerged. Reconsideration of the application of the term "geographic atrophy" in the context of age-related macular

    A profound nursing shortage exists in India where nurses are increasingly outmigrating to practice nursing in surrounding countries and abroad. This is important globally because countries with the lowest nursing and healthcare workforce capacities have the poorest health outcomes. This review sought to synthesize and unify the evidence about nurse migration from India and includes a look at nurse retention within India. A comprehensive literature review was performed to synthesize and unify both qualitative and quantitative research. Bibliographic databases searched included CINAHL, MEDLINE, PsycINFO, and EconLit using associated keywords for empirical and descriptive literature published between January 2004 and May 2014. Hand searches of the Nursing Journal of India from 2004 to February 2014 and the Journal of Nursing Research Society of India from its inception in 2007-February 2014 were also completed. 29 studies were selected and analyzed for the review. Data were appraised for quality; reduced through sub-categorization; extracted; and coded into a framework. Thematic interpretation occurred through comparing and contrasting performed by multiple reviewers. Findings included an exponential growth in nurse recruitment efforts, nurse migration, and a concomitant growth in educational institutions within India with regional variations in nurse migration patterns. Decision-making factors for migration were based on working conditions, salience of family, and the desire for knowledge, skill, technology, adventure and personal enrichment. Challenges associated with migration included questionable recruiting practices, differing scopes of practice encountered after migration and experiences of racism and cultural differences. A shift toward a positive transformation of nursing status in India has resulted in an increased respect for individual nurses and the profession of nursing. This was attributed to the increased globalization of nursing. Results from this

    In support of the goals of Department of Homeland Security’s (DHS) National Protection and Programs Directorate and the Federal Emergency Management Agency, the DHS Office of Science and Technology is seeking to develop and/or modify consequence assessment tools to enable drinking water systems owner/operators to estimate the societal and economic consequences of drinking water disruption due to the threats and hazards. This work will expand the breadth of consequence estimation methods and tools using the best-available data describing water distribution infrastructure, owner/assetlevel economic losses, regional-scale economic activity, and health. In addition, this project will deploy the consequence methodology and capability within a Web-based platform. This report is intended to support DHS effort providing a review literature review of existing assessment tools of water and wastewater systems consequences to disruptions. The review includes tools that assess water systems resilience, vulnerability, and risk. This will help to understand gaps and limitations of these tools in order to plan for the development of the next-generation consequences tool for water and waste water systems disruption.

    Process Mining focuses on extracting knowledge from data generated and stored in corporate information systems in order to analyze executed processes. In the healthcare domain, process mining has been used in different case studies, with promising results. Accordingly, we have conducted a literature review of the usage of process mining in healthcare. The scope of this review covers 74 papers with associated case studies, all of which were analyzed according to eleven main aspects, including: process and data types; frequently posed questions; process mining techniques, perspectives and tools; methodologies; implementation and analysis strategies; geographical analysis; and medical fields. The most commonly used categories and emerging topics have been identified, as well as future trends, such as enhancing Hospital Information Systems to become process-aware. This review can: (i) provide a useful overview of the current work being undertaken in this field; (ii) help researchers to choose process mining algorithms, techniques, tools, methodologies and approaches for their own applications; and (iii) highlight the use of process mining to improve healthcare processes.

    2013-05-01

    The purpose of this review was to summarize recent developments regarding photodynamic therapy (PDT) in the field of dentistry. A review of pertinent literature was carried out in PubMED to determine the current position of PDT applications in dentistry. One hundred thirteen relevant articles were retrieved from PubMED by inserting the keywords "photodynamic therapy", "dentistry", "periodontology", "oral surgery", and "endodontics". It is anticipated that this overview will create a specific picture in the practitioner's mind regarding the current status and use of PDT. In spite of different results and suggestions brought about by different researchers, PDT can be considered as a promising and less invasive technique in dentistry. PDT seems to be an effective tool in the treatment of localized and superficial infections. Within the limitations of the present review, it can be concluded that although PDT cannot replace antimicrobial therapy at its current stage, it may be used as an adjunctive tool for facilitating the treatment of oral infections. Oral infections (such as mucosal and endodontic infections, periodontal diseases, caries, and peri-implantitis) are among the specific targets where PDT can be applied. Further long-term clinical studies are necessary in establishing a more specific place of the technique in the field of dentistry.

  16. Harmful effects of shisha: literature review

    PubMed Central

    2014-01-01

    Tobacco is a preventable cause of morbidity and mortality across the world. A recently infamous way of smoking tobacco is shisha. Shisha smoking is also known as water pipe, hookah and Narghile smoking. The percentage of shisha smokers is on the rise rapidly spanning the globe. A literature review was conducted to identify all evidence on the epidemiological variations and health effects of shisha smoking. “Pub med” is used as a searching tool to identify all relevant empirical studies conducted worldwide. A qualitative overview of evidence is presented. Exposure to Shisha smoking is significantly associated with low infant weight, heart rate variations, hyperglycemia and hypertriglyceridemia. Increased risk of carcinoma is also leagued with it including carcinomas of the pancreas and lung being at the forefront. In conclusion, this review identifies grounds of several adverse conditions being associated with the habit of shisha smoking. It also evaluates the relevant epidemiological variations around the globe. The review culminates in the importance of enlightening shisha smokers regarding its deleterious effects. PMID:24708750

    It is not known what constitutes the optimal emergency management system, nor is there a consensus on how effectiveness and efficiency in emergency response should be measured or evaluated. Literature on the role and tasks of commanders in the prehospital emergency services in the setting of mass-casualty incidents has not been summarized and published. This comprehensive literature review addresses some of the needs for future research in emergency management through three research questions: (1) What are the basic assumptions underlying incident command systems (ICSs)? (2) What are the tasks of ambulance and medical commanders in the field? And (3) How can field commanders' performances be measured and assessed? A systematic literature search in MEDLINE, PubMed, PsycINFO, Embase, Cochrane Central Register of Controlled Trials, Cochrane Library, ISI Web of Science, Scopus, International Security & Counter Terrorism Reference Center, Current Controlled Trials, and PROSPERO covering January 1, 1990 through March 1, 2014 was conducted. Reference lists of included literature were hand searched. Included papers were analyzed using Framework synthesis. The literature search identified 6,049 unique records, of which, 76 articles and books where included in qualitative synthesis. Most ICSs are described commonly as hierarchical, bureaucratic, and based on military principles. These assumptions are contested strongly, as is the applicability of such systems. Linking of the chains of command in cooperating agencies is a basic difficulty. Incident command systems are flexible in the sense that the organization may be expanded as needed. Commanders may command by direction, by planning, or by influence. Commanders' tasks may be summarized as: conducting scene assessment, developing an action plan, distributing resources, monitoring operations, and making decisions. There is considerable variation between authors in nomenclature and what tasks are included or highlighted

    Electronic whiteboards are being introduced into hospitals to communicate real-time patient information instantly to staff. This paper provides a preliminary review of the current state of evidence for the effect of electronic whiteboards on care processes and patient outcomes. A literature search was performed for the dates 1996 to 2014 on MEDLINE, EMBASE, IEEE Xplore, Science Direct, and the ACM Digital Library. Thirteen papers, describing 11 studies, meeting the inclusion criteria were identified. The majority of studies took place in the Emergency Department. While studies looked at the impact of electronic whiteboards on the process of care, there is an absence of evidence concerning impact on patient outcomes. There is a need for robust research measuring the impact of electronic whiteboards on inpatient care.

    Current thought and research positions which may allow for an improved capability to understand the impact of introducing automation to an existing system are established. The orientation was toward the type of studies which may provide some general insight into automation; specifically, the impact of automation in human performance and the resulting system performance. While an extensive number of articles were reviewed, only those that addressed the issue of automation and human performance were selected to be discussed. The literature is organized along two dimensions: time, Pre-1970, Post-1970; and type of approach, Engineering or Behavioral Science. The conclusions reached are not definitive, but do provide the initial stepping stones in an attempt to begin to bridge the concept of automation in a systematic progression.

    2007-11-01

    This article is part of a wider study entitled Value of Nursing, and contains the literature search from electronic databases. Key words for the search included 'values of nursing', 'values in nursing', 'organisational values' and 'professional identity'. Thirty-two primary reports published in English between 2000 and 2006 were identified. The findings highlight the importance of understanding values and their relevance in nursing and how values are constructed. The value of nursing is seen to be influenced by cultural change, globalization, and advancement in technology and medicine. These factors are crucial in providing a more structured and measured view of what nursing is, which will result in greater job satisfaction among nurses, better nurse retention and enhanced patient care within a supportive and harmonious organization. The findings of this review have implications for policy makers in recruitment and retention in determining the global value of nursing.

    Microgrids are an increasingly common component of the evolving electricity grids with the potential to improve local reliability, reduce costs, and increase penetration rates for distributed renewable generation. The additional complexity of microgrids often leads to increased investment costs, creating a barrier for widespread adoption. These costs may result directly from specific needs for islanding detection, protection systems and power quality assurance that would otherwise be avoided in simpler system configurations. However, microgrids also facilitate additional value streams that may make up for their increased costs and improve the economic viability of microgrid deployment. This paper analyses the literature currently available on research relevant to value streams occurring in microgrids that may contribute to offset the increased investment costs. A review on research related to specific microgrid requirements is also presented.

    CCS research has been focused on CO2 storage in geologic formations, with many potential risks. An alternative to conventional geologic storage is carbon mineralization, where CO2 is reacted with metal cations to form carbonate minerals. Mineralization methods can be broadly divided into two categories: in situ and ex situ. In situ mineralization, or mineral trapping, is a component of underground geologic sequestration, in which a portion of the injected CO2 reacts with alkaline rock present in the target formation to form solid carbonate species. In ex situ mineralization, the carbonation reaction occurs above ground, within a separate reactor or industrial process. This literature review is meant to provide an update on the current status of research on CO2 mineralization. 2

    This report fulfills the M4 milestone M4FT-13OR08220112, "Report Documenting Experimental Activities." The purpose of this report is to document the results of a literature review conducted of studies related to the vibration and shock associated with the normal conditions of transport for rail shipments of used nuclear fuel from commercial light-water reactors. As discussed in Adkins (2013), the objective of this report is to determine if adequate data exist that would enable the impacts of the shock and vibration associated with the normal conditions of transport on commercial light-water reactor used nuclear fuel shipped in current generation rail transportation casks to be realistically modeled.

  4. A review of recent literature on plague

    Pollitzer, R.

    1960-01-01

    In his comprehensive monograph on plague, published by WHO in 1954, Dr Pollitzer pointed out that despite the marked drop in the incidence of this disease in recent years, he considered it impossible for various reasons to be complacent about the situation. Since this monograph appeared, plague has shown a truly spectacular decrease, but in case this is partly the outcome of a natural periodicity of the infection, the author still feels that the disease ”should be given continued attention by those interested in global public health”. To this end he summarizes here the latest information on the subject, his review covering not only works published since 1954, but also some earlier literature (particularly from the USSR) which was not available to him at the time of preparation of his monograph.

    Mozart ear is a congenital auricular deformity, which is mainly characterized by a bulging appearance of the anterosuperior portion of the auricle, a convexly protruded cavum conchae, and a slit-like narrowing of the orifice of the external auditory meatus. It is said to be uncommon, and because no one has yet fully described neither the disease nor the treatment, the concept of Mozart ear has not been unified. This report describes a case of a 13-year-old girl presented with an unusual congenital deformity which showed the features of Mozart ear. It is an extremely rare deformity that only about 4 clinical cases have been reported in medical literature thereby a treatment method has not been fully discussed. For surgical correction of our cases, we excised deformed conchal cartilage, turned it over, regrafted, and maintained a cosmetically positive result. We also reviewed and described the origin, current concept, and treatment method of Mozart ear.

  6. Anabolic steroids: a review of the literature.

    1984-01-01

    The use of anabolic steroids by athletes is controversial. On the one hand, many athletes believe that steroids improve athletic performance and thus provide an advantage to those who use them. On the other hand, the medical and scientific communities believe that inadequate scientific data exist to support the claim that anabolic steroids can improve athletic performance while overwhelming scientific data demonstrate their deleterious effects. Therefore, a large information and credibility gap concerning anabolic steroids exists between the athletes and the medical and scientific communities. We believe that this gap can be closed if both groups are better informed about anabolic steroids. We provide a detailed review of the literature on anabolic steroids that provides to the reader the information needed to make an informed decision on the relative risks and benefits of anabolic steroids to the athlete.

    The scope of the research was to increase the understanding of social media's influence among nurses while highlighting gaps in the literature and areas for further research. The search of PubMed database was performed in November 2015, using terms to identify peer-reviewed articles that describe the use of social media for nursing students or nurse practitioners. A systematic approach was used to retrieve papers and extract relevant data. There were identified 23 full text articles involving social media and nurse-related terminology. The majority of the studies were interventional (n = 20) that assessed social media as a teaching tool. Podcasts, Multiplayer virtual worlds and mixed social media platforms has also been assessed. Social media is used as a tool of information for nurses mainly as the means for engaging and communicating.

    Much has been written about the causes, prevention, and nursing management of pressure ulcers. A review of current literature on the subject reveals that, in spite of the enormity of information available, the problem continues to consume a large percentage of nursing time and energy. Studies of aggressive prevention and ongoing continuing education programs have demonstrated significant reduction of incidence and time of treatment, as well as dramatic cost savings. The Agency for Health Care Policy and Research (AHCPR) has recommended that all patients at risk for pressure ulcer development be placed on some form of pressure-reducing support surface. There is a wide variety of these products available, but a surprisingly limited quantity of published articles specifically compare the efficacy of one product to another.

    A literature review was carried out focusing on the main factors associated with suicidal ideation, attempts and completed suicide in elders. The following databases were searched: MEDLINE, PsychINFO, SciELO and Biblioteca Virtual em Violência e Saúde da BIREME (BIREME's Violence and Health Virtual Library), referring to the period from 1980 to 2008. Fifty-two references were selected and analyzed. They showed a strong relationship among suicide ideation, attempt and completion in elderly individuals, which results from the interaction of complex physical, mental, neurobiological and social factors. Suicide associated with depression in the elderly can be prevented, provided the person is properly treated. In Brazil, it is necessary to invest in research, given the persistent increase in suicide rates among aged people, especially among males.

    The resurgence of airships has created a need for dynamics models and simulation capabilities adapted to these lighter-than-air vehicles. However, the modeling techniques for airship dynamics have lagged behind and are less systematic than those for fixed-wing aircraft. A state-of-the-art literature review is presented on airship dynamics modeling, aiming to provide a comprehensive description of the main problems in this area and a useful source of references for researchers and engineers interested in modern airship applications. The references are categorized according to the major topics in this area: aerodynamics, flight dynamics, incorporation of structural flexibility, incorporation of atmospheric turbulence, and effects of ballonets. Relevant analytical, numerical, and semi-empirical techniques are discussed, with a particular focus on how the main differences between lighter-than-air and heavier-than-air aircraft have been addressed in the modeling. Directions are suggested for future research on each of these topics.

    Myxedema ascites caused by hypothyroidism is rare, so its diagnosis is often delayed and patients frequently receive unnecessary procedures such as liver biopsies and exploratory laparotomies. We report a 71-yr-old man with clinical ascites that was the first manifestation of hypothyroidism, and which resolved completely in response to thyroid hormone replacement therapy. To our knowledge, this is the first report of myxedema ascites in Korea. A review of the literature revealed 51 well-documented cases of myxedema ascites. Analyses of ascites from patients in this condition usually show high protein (>2.5 g/dL) and low white blood cell counts, with a high proportion of lymphocytes. A consistent feature is the good response to thyroid hormone replacement therapy, which has always led to resolution of the ascites. Myxedema ascites is thus rare but easy to treat; it should be borne in mind, especially if the ascites fluid has a high protein content. PMID:16891828

    Psychiatric Intensive Care Units (PICU) have been part of most inpatient psychiatric services for some time, although information about their functioning and outcome has not previously been collated. To conduct a systematic literature review to assess the current state of knowledge about such services. A search of electronic databases was undertaken, followed by obtaining additional references from items obtained. Over 50 papers in English containing some empirical data were identified. Most studies were retrospective. Typical PICU patients are male, younger, single, unemployed, suffering from schizophrenia or mania, from a Black Caribbean or African background, legally detained, with a forensic history. The most common reason for admission is for aggression management, and most patients stay a week or less. Evidence of the efficacy of PICU care is very poor. Most research so far has been small scale, and more substantial work using better methodologies is clearly required.

    Cognitive rest has been suggested as a treatment for school athletes who have sustained a concussion, but the concept has rarely been defined. The purpose of this article is to provide a comprehensive definition of cognitive rest, based on an integrative literature review. The method of synthesis was guided by Avant and Walker's concept analysis format. The importance of rest is discussed as a nursing intervention, and model cases are presented to clarify the concept. Three defining attributes of cognitive rest are established: freedom from physical or mental discomfort, abstinence from mental exertion, and mental and emotional balance. Empirical referents are given as well as a suggested protocol to enable school nurses to form cognitive rest and return-to-classroom protocols that can be adapted to individual school settings. © The Author(s) 2015.

    PubMed

    Love, Katie L

    2016-01-01

    This study presents a systematic literature review exploring the uses and potential benefits of Black Feminism in nursing research. Black Feminism may benefit knowledge development for nursing in a variety of ways, such as illuminating the multifaceted factors of Black women's identities in helping scholars move away from generalization of experiences, to improve understanding of health disparities, and making such changes by broadening the social consciousness of the nurse researchers, who are predominantly White. Discrimination in health disparities may be deconstructed if the focus is placed on asking different research questions and offering different interventions with the social structures that contributes to such actions. When Black Feminism guides the research method (including research questions and analysis), the accuracy of representing the experiences of Black women is increased. In this research, Black Feminism highlights experience, coping mechanisms, spiritual values, a tradition of strength, and a holistic view of identity.

    Data on tolerability and safety of aripiprazolo during pregnancy and in childbirth are so far limited. Aim of the present study is to provide a review of the literature on the safety profile of aripiprazole during pregnancy and on maternal and neonatal outcomes, including two cases coming from our database (www.degradatabase.it). Medline database was searched for English language articles by using the following keywords: "aripiprazole", "atypical antipsychotic", "major malformations", "perinatal complications", "pregnancy". We reported 2 cases of women treated with aripiprazole during their pregnancy at the Clinic of Affective Disorders in Pregnancy and Postpartum of the United Hospital of Ancona (DEGRA Center - www.depressionegravidanza.it). The data available in the literature did not provide clear evidence about the safety and potential risks related to this drug during pregnancy. Data coming from our database did not detected any malformations and perinatal complications after exposure to aripiprazole in 2 newborns beyond the first trimester of pregnancy. From the evidence available, aripiprazole seems to be an antipsychotic effective and well tolerated in the treatment of women with psychotic disorders in pregnancy. However, further studies are needed to better establish the safety of aripiprazole during pregnancy, particularly as the risk of major malformtions and perinatal complications is concerned.

    Numerous brands and types of artificial tears are available on the market for the treatment of dysfunctional tear syndrome. Past literature has focused on comparing the components of these products on patient’s clinical improvement. The wide array of products on the market presents challenges to both clinicians and patients when trying to choose between available tear replacement therapies. Different formulations affect patients based on etiology and severity of disease. In order to provide an unbiased comparison between available tear replacement therapies, we conducted a literature review of existing studies and National Institutes of Health clinical trials on commercially available, brand name artificial tears. Outcomes evaluated in each study, as well as the percent of patients showing clinical and symptomatic improvement, were analyzed. Fifty-one studies evaluating different brands of artificial tears, and their efficacy were identified. Out of the 51 studies, 18 were comparison studies testing brand name artificial tears directly against each other. Nearly all formulations of artificial tears provided significant benefit to patients with dysfunctional tear syndrome, but some proved superior to others. From the study data, a recommended treatment flowchart was derived. PMID:25114502

    Abstract Nocardia are Gram-positive filamentous bacteria responsible for infections ranging from opportunistic life-threatening disseminated diseases to chronic skin and soft-tissue infections. Even if virtually all organs can be infected, articular involvement is rare. Therefore, we report 3 recent cases and performed a literature review of cases of Nocardia arthritis in order to describe clinical features, therapeutic challenges, and outcome of these patients. Among 34 patients (31 in the literature plus our 3 cases), 21 (62%) were due to hematogenous dissemination, 9 (26%) were due to direct bacterial inoculation through the skin, and in 4 cases, the mechanism of infection was unknown. Four out of these 34 cases occurred on prosthetic joints. Whereas hematogenous infections mostly occurred in immunocompromised hosts (17 of 21, 81%), direct inoculation was mostly seen in immunocompetent patients. Eighty-two percent of patients (28 out of 34) received trimethoprim-sulfamethoxazole-containing regimens and median antibiotic treatment duration was 24 weeks (range, 12–120) for hematogenous infections and 12 weeks (range, 6–24) for direct inoculations. Outcome was favorable in 27 cases despite unsystematic surgical management (17 cases) without sequelae in 70% of the cases. Nocardia arthritis is rare but its management is complex and should rely on a combined approach with rheumatologist, infectious diseases expert, and surgeon. PMID:26496274

    The presence of social support, and more recently, connection, has been linked to multiple health benefits and longevity measures and the lack of connection is associated with premature morbidity and mortality. Connected health is a growing industry, and we were interested in determining whether or not scholars in the field have established the ways in which technology could facilitate or promote connection between patients and healthcare providers. This integrative literature review sought to collect and analyze research studies addressing social support or connection in a sample of patients with diabetes to evaluate the social support or connection metrics in use, the type of technology deployed by researchers to achieve connection, and to assess the state of the science in this area. We hypothesized that being connected to someone who cares is good for your health. We believe this holds true even when connection is accomplished with mobile technologies. Thirty five studies were included in this review, 21 utilized technology to enhance patient-provider connection. The articles included in this review were from a total of more than nine countries and took place in hospital, physician office, and community settings. They represented people from childhood through to old age. Technologies evaluated include: telephone interventions, email, text messaging, interactive voice response (IVR), video blogs, apps, websites, and social media. There were multiple operational definitions of social support and self-management used as variables within the studies. Findings from this review suggest that being connected does matter to patients with diabetes, and being connected to family matters the most, even though the associations are complex and not always predictable. Furthermore, patients with diabetes will utilize a variety of technologies to connect with healthcare providers, team members, and even other people with the same disease.

    The authors reviewed the literature, published from 1970 through December 2009, on biomechanical research in dance. To identify articles, the authors used search engines, including PubMed and Web of Science, five previous review articles, the Dance Medicine and Science Bibliography, and reference lists of theses, dissertations, and articles being reviewed. Any dance research articles (English language) involving the use of electromyography, forceplates, motion analysis using photography, cinematography or videography, and/or physics analysis were included. A total of 89 papers, theses/dissertations, and abstracts were identified and reviewed, grouped by the movement concept or specialized movements being studied: alignment (n = 8), plié (8), relevé (8), passé (3), degagé (3), développé (7), rond de jambe (3), grand battement (4), arm movements (1), forward stepping (3), turns (6), elevation work (28), falls (1), and dance-specific motor strategies (6). Several recurring themes emerged from these studies: that elite dancers demonstrate different and superior motor strategies than novices or nondancers; that dancers perform differently when using a barre as opposed to without a barre, both in terms of muscle activation patterns and weight shift strategies; that while skilled dancers tend to be more consistent across multiple trials of a task, considerable variability is seen among participants, even when matched for background, years of training, body type, and other variables; and that dance teachers recommend methods of achieving movement skills that are inconsistent with optimal biomechanical function, as well as inconsistent with strategies employed by elite dancers. Measurement tools and the efficacy of study methodologies are also discussed.

The search yielded a total of 576 hits, 331 titles and abstracts were screened, 42 papers were retrieved and reviewed and 23 articles were included. Analysis reveals an overarching theme of uncertainty in diagnosing dying and two subthemes: (1) 'characteristics of dying' involve dying trajectories that incorporate physical, social, spiritual and psychological decline towards death; (2) 'treatment orientation' where decision making related to diagnosing dying may remain focused towards biomedical interventions rather than systematic planning for end-of-life care. The findings of this review support the explicit recognition of 'uncertainty in diagnosing dying' and the need to work with and within this concept. Clinical decision making needs to allow for recovery where that potential exists, but equally there is the need to avoid futile interventions. Published by the BMJ Publishing Group Limited.

    Objective Burnout is a state of mental and physical exhaustion related to work or care giving activities. Burnout during residency training has gained significant attention secondary to concerns regarding job performance and patient care. This article reviews the relevant literature on burnout in order to provide information to educators about its prevalence, features, impact, and potential interventions. Methods Studies were identified through a Medline and PsychInfo search from 1974 to 2009. Fifty-one studies were identified. Definition and description of burnout and measurement methods are presented followed by a thorough review of the studies. Results An examination of the burnout literature reveals that it is prevalent in medical students (28%–45%), residents (27%–75%, depending on specialty), as well as practicing physicians. Psychological distress and physical symptoms can impact work performance and patient safety. Distress during medical school can lead to burnout, which in turn can result in negative consequences as a working physician. Burnout also poses significant challenges during early training years in residency. Time demands, lack of control, work planning, work organization, inherently difficult job situations, and interpersonal relationships, are considered factors contributing to residents' burnout. Potential interventions include workplace-driven and individual-driven measures. Workplace interventions include education about burnout, workload modifications, increasing the diversity of work duties, stress management training, mentoring, emotional intelligence training, and wellness workshops. Individual-driven behavioral, social, and physical activities include promoting interpersonal professional relations, meditation, counseling, and exercise. Conclusions Educators need to develop an active awareness of burnout and ought to consider incorporating relevant instruction and interventions during the process of training resident physicians

    2011-01-01

    SUMMARY Aim of the work Aim of the work was to execute a review of the international literature about the cementation of zirconia restorations, analyzing the properties of the cements most commonly used in clinical activities. Materials and methods It was performed, through PubMed, a bibliographic search on the international literature of the last 10 years using the following limits: studies in English, in vitro studies, randomized clinical trial, reviews, meta-analysis, guide-lines. Were excluded from the search: descriptive studies, case reports, discussion articles, opinion’s leader. Results From studies results that common surface treatments (silanization, acid etching) are ineffective on zirconia because it has an inert surface without glassy component (on which this surface treatments act primarily), instead the sandblasting at 1atm with aluminium oxide (Al2O3) results significantly effective for the resulting roughening that increase the surface energy and the wettability of the material. Furthermore it has been shown that zinc phosphate-based cements, Bis-GMA-based and glass-ionomer cements can’t guarantee a stable long-term adhesion, instead resin cements containing phosphate monomer 10-methacryloyloxyidecyl-dihyidrogenphosphate (MDP) have shown higher adhesion and stability values than the other cements. In particular, it has seen that bond strength of zirconia copings on dentin, using MDP-based cement, is about 6,9MPa; this value is comparable to that obtained with gold copings cementation. Conclusions Analyzed studies have led to the following conclusions: sandblasting with aluminium oxide (Al2O3) is the best surface treatment to improve adhesion between resin cements and zirconia; resin cements containing phosphate ester monomers 10-methacryloyloxyidecyl-dihyidrogenphosphate (MDP) have shown in the studies an higher bond strength and stability after ageing treatment; the best procedure for cementing zirconia restorations results the combination of

    We present a young asymptomatic woman with splenomegaly and a large isolated splenic mass demonstrated by ultrasonography, /sup 99m/Tc sulfur colloid, and gallium scintigraphy studies. Computerized tomography (CT) and three-phase 99mTc-labeled red blood cell imaging suggested a malignant lesion. Repeated sonographically guided fine needle aspiration (FNA) obtained only blood, suggesting the possible vascular nature of the tumor. Splenectomy established the diagnosis of splenic hemangioma (SH) with marked sclerotic changes. We conclude from this case that (1) the sclerotic and cystic changes in the SH and the abdominal lymphadenopathy could explain why the three-phase red blood cell and CT scanning, respectively, suggested that the lesion was malignant rather than benign; (2) guided FNA of a splenic mass suspected to be hemangioma may be an additional safe and useful diagnostic procedure. Multiple aspirations yielding blood alone suggest hemangioma and may prevent an unnecessary operation. To the best of our knowledge, this is the first reported case in the literature of FNA of splenic hemangioma.

    Background: Epithelioid hemangioendothelioma (EHE) is a rare sarcoma of vascular origin, which is clinically and histologically intermediate between benign hemangioma and angiosarcoma. It is most commonly found in the liver, lung, and bone, however, 46 intracranial cases have been reported in the literature, of which this is the fifth reported suprasellar tumor. Case Description: A 45-year-old woman developed progressive lethargy, somnolence, and memory decline over the course of 6 months. On computed tomography (CT), she was found to have a large hypothalamic mass and underwent subtotal resection via a bifrontal craniotomy. Conclusions: While primary intracranial EHE is an uncommon presentation of a rare tumor, the suprasellar region does not seem to be an unusual location when it does occur. Prognosis is generally good, and may be better for primary intracranial disease than that for EHE originating elsewhere. Surgery is the first line of therapy, with variable benefit from adjuvant chemotherapy or radiation when total resection is not possible. Chemotherapeutic approaches in current use are directed at preventing endothelial proliferation. PMID:27656318

    To report a case of a bladder cavernous hemangioma, as well as the main features of its diagnosis and treatment. A 74 year old patient, regular smoker, presented with total macroscopic hematuria of moderate intensity with large rounded clots. On physical examination the patient's mucous membranes color was normal, and digital rectal examination showed a normal size prostate with fibroelastic consistency. An abdominal ultrasound was performed showing a slight bladder bottom thickening in addition to free clots and a homogeneous and normal prostate. Cystoscopy confirmed the presence of a sessile violet-colored rounded retrotrigonal tumor, 2 cm in diameter and 0.5 in height; it was immediately resected. The pathological study reported cavernous hemangioma. Patient's evolution has been satisfactory. Bladder cavernous hemangioma is a rare cause of hematuria, and transurethral resection of the small size lesions constitutes an effective option as a definitive surgical treatment.

    Schizophrenia represents a major burden for patients, their families, healthcare systems and societies. The objective of this literature review is to document the economic burden of schizophrenia. The literature search was performed using the MEDLINE-PUBMED database and the following keywords: schizophrenia and cost, burden of disease, qaly or price. The grey literature search was performed using several databases (e.g. Banque de Données en Santé Publique) and the Google Scholar(®) web search engine. The studies that met the following criteria were included: published since 1998, written in English or French, studied OECD countries and presented costs data that were given in monetary terms. The costs data identified in the literature were classified into the following five main categories: cost for healthcare system, cost for social and medico-social system (medico-social system is a French specificity), cost for prison and legal systems, cost of informal care given by family, and cost associated with productivity losses. To improve comparability, costs were reported as a percentage of health care expenditures and as a per-ten-thousand of GDP (gross domestic product). Among the 201 articles identified as potentially relevant to the topic, nine were included in the literature review. Schizophrenia health care costs ranged from four (Ireland) to 140000 of GDP (Spain). Hospital care was the main health care cost driver but ranged from 19 (USA) to 92% (Belgium) demonstrating a great variability in treatment patterns. The costs for social and medico-social system ranged from 1.3 (Korea) to 13.80000 of GDP (USA) and the costs of informal caregivers ranged from 1.2 (Australia) to 12.70000 of GDP (Spain). The productivity losses associated with unemployment ranged from 6.2 (Australia) to 21.30000 of GDP (USA). The productivity losses associated with premature mortality ranged from less than 0.01 (Canada) to 3.850000 (Ireland). Among others factors, such as targeted

    Despite all the investment in research, uncertainty persists in anticipatory grief (AG) literature, concerning its nuclear characteristics and definition. This review aimed to synthesize recent research in order to develop further knowledge about the family experience of AG during a patient's end of life. An integrative review was performed using standard methods of analysis and synthesis. The electronic databases Medline, Web of Knowledge, and EBSCO and relevant journals were systematically searched since 1990 to October 2015. Twenty-nine articles were selected, the majority with samples composed of caregivers of terminally ill patients with cancer. From systematic comparison of data referring to family end-of-life experience emerged 10 themes, which correspond to AG nuclear characteristics: anticipation of death, emotional distress, intrapsychic and interpersonal protection, exclusive focus on the patient care, hope, ambivalence, personal losses, relational losses, end-of-life relational tasks, and transition. For the majority of family caregivers in occidental society, AG is a highly stressful and ambivalent experience due to anticipation of death and relational losses, while the patient is physically present and needed of care, so family must be functional and inhibit grief expressions. The present study contributes to a deeper conceptualization of this term and to a more sensitive clinical practice.

    A literature review of nurses' job satisfaction. Little is known about factors evoking job satisfaction among nurses, whereas more is known about stress, burnout and dissatisfaction. The positive viewpoint is an important research area and needs to be studied. Original studies were accessed by a systematic search from electronic databases (Abi/Inform, PsycINFO, Cinahl and Medline Ovid) using the keywords 'nurses' and 'job satisfaction' and chosen by certain criteria. The data chosen for this review consist of 21 scientific articles. Data were analysed using content analysis. and conclusions Most of the studies are quantitative studies, the majority of them were conducted in the United States. Job satisfaction at work varies in different specialty areas of nursing work. Two significant themes in job satisfaction are interpersonal relationships between nurses and patient care. Different ways of organizing work are also relevant for job satisfaction. Nurse managers have a strong role in promoting nurses' job satisfaction: attention should be paid especially to strengthening nurses' interpersonal relationships and facilitate nurses' capacity to deliver high-quality patient care.

    Trisomy 13 mosaicism is a rare genetic disorder affecting a small minority of all trisomy 13 cases. It occurs when two cell populations that are karyotypically different are present in the same individual and are derived from a single zygote. As a rule, the phenotype is mitigated to a less dysmorphic appearance and longer survival, making genetic counseling a difficult task. Capillary hemangiomas are a common feature of full trisomy 13, seen in 27-56% of all cases. We report on an 18-months-old girl with extensive cutaneous anomalies, mild dysmorphic features, and slight psychomotor delay, without structural defects and provide an up-to-date review of all cases of trisomy 13 mosaicism with skin involvement. To our knowledge, this is the second clinical report of a patient with trisomy 13 mosaicism with hemangiomas and port wine stains, but no structural defects. © 2015 Wiley Periodicals, Inc.

  13. Personal Health Records: A Systematic Literature Review

    PubMed Central

    2017-01-01

    Background Information and communication technology (ICT) has transformed the health care field worldwide. One of the main drivers of this change is the electronic health record (EHR). However, there are still open issues and challenges because the EHR usually reflects the partial view of a health care provider without the ability for patients to control or interact with their data. Furthermore, with the growth of mobile and ubiquitous computing, the number of records regarding personal health is increasing exponentially. This movement has been characterized as the Internet of Things (IoT), including the widespread development of wearable computing technology and assorted types of health-related sensors. This leads to the need for an integrated method of storing health-related data, defined as the personal health record (PHR), which could be used by health care providers and patients. This approach could combine EHRs with data gathered from sensors or other wearable computing devices. This unified view of patients’ health could be shared with providers, who may not only use previous health-related records but also expand them with data resulting from their interactions. Another PHR advantage is that patients can interact with their health data, making decisions that may positively affect their health. Objective This work aimed to explore the recent literature related to PHRs by defining the taxonomy and identifying challenges and open questions. In addition, this study specifically sought to identify data types, standards, profiles, goals, methods, functions, and architecture with regard to PHRs. Methods The method to achieve these objectives consists of using the systematic literature review approach, which is guided by research questions using the population, intervention, comparison, outcome, and context (PICOC) criteria.

    Fifteen years ago, Baechler presented his "strategic theory of suicide". Following a viewpoint initiated at the end of the 1950's by Stengel and Cook, he proposed the more accomplished theoretical development of suicidal functions. We propose a critical review of international empiric literature following this approach. We carried out a bibliographic research on PsychINFO(®) databank, crossing terms of suicide attempt, deliberate self-harm and parasuicide, to reasons, motivations, functions, intentions. Thirty-one articles were selected. They cover a period ranging from 1971 to 2008, and from Europe to the USA. Few studies have been conducted in France, but international literature has grown since 1970, and some questionnaires have been created: e.g. the Motives for Parasuicide Questionnaire (MPQ, Kerkhof et al., 1993 [28]) and the Reasons for Attempting Suicide Questionnaire (RASQ, Holden et al., 1998 [24]). The first intentions mentioned are internal perturbations type: to get relief, to escape, cannot endure situation or thoughts any longer, loss of control. They are often blended with interpersonal intentions: to make people understand what they felt, to seek help, to make things easier for others, while more aggressive, punitive or manipulative functions are seldom reported. Women report more reasons than men, but do not differ in their pattern of intentions. Suicide attempters report varying desire to die across studies. Some inconsistent distinctions can be made from age and gender but few from subjects' suicidal history. One can wonder if subject's answers are really honest, particularly in regards to social desirability. Links between internal perturbations and suicidal intent, hopelessness, and depression are logically found, which aims to give evidence that, at least for this dimension, subjects give true answers, but which also point out the redundant aspect of some items of the suicidant functions scales (e.g. "to die"). Today, it turns out that this

    Studies have found that deaf individuals have higher rates of psychiatric disorder than those who are hearing, while at the same time encountering difficulties in accessing mental health services. These factors might increase the risk of suicide. However, the burden of suicidal behaviour in deaf people is currently unknown. The aim of the present review was to provide a summary of literature on suicidal behaviour with specific reference to deaf individuals. The objectives of the review were to establish the incidence and prevalence of suicidal behaviour in deaf populations; describe risk factors for suicidal behaviour in deaf populations; describe approaches to intervention and suicide prevention that have been used in deaf populations. A number of electronic databases (e.g. Medline, PsycINFO, CINAHL, EMBASE, Dissertation Abstracts International, Web of Science, ComDisDome, ASSIA, Education Sage Full Text, Google Scholar, and the grey literature databases FADE and SIGLE) were explored using a combination of key words and medical subject headings as search terms. Reference lists of papers were also searched. The Science and Social Sciences Citation Index electronic databases were used to identify studies that had cited key papers. We also contacted experts and organisations with an interest in the field. Very few studies focussed specifically on suicide in deaf populations. Those studies that were included (n = 13) generally involved small and unrepresentative samples. There were limited data on the rate of suicidal behaviour in deaf people. One study reported evidence of hearing impairment in 0.2% of all suicide deaths. Another found that individuals with tinnitus seen in specialist clinics had an elevated rate of suicide compared to the general population. The rates of attempted suicide in deaf school and college students during the previous year ranged from 1.7% to 18%, with lifetime rates as high as 30%. Little evidence was found to suggest that risk factors for

    There is ongoing interest in including grey literature in systematic reviews. Including grey literature can broaden the scope to more relevant studies, thereby providing a more complete view of available evidence. Searching for grey literature can be challenging despite greater access through the Internet, search engines and online bibliographic databases. There are a number of publications that list sources for finding grey literature in systematic reviews. However, there is scant information about how searches for grey literature are executed and how it is included in the review process. This level of detail is important to ensure that reviews follow explicit methodology to be systematic, transparent and reproducible. The purpose of this paper is to provide a detailed account of one systematic review team's experience in searching for grey literature and including it throughout the review. We provide a brief overview of grey literature before describing our search and review approach. We also discuss the benefits and challenges of including grey literature in our systematic review, as well as the strengths and limitations to our approach. Detailed information about incorporating grey literature in reviews is important in advancing methodology as review teams adapt and build upon the approaches described.

    Hemangioma is a mesenchymal benign tumor formed by blood vessels. Anomalies affect up to 10% of children and they are more common in females than in males. The aim of our study was to compare the treatment efficacy, namely the curative effect and adverse events, such as loss of pigment and appearance of scarring, between classical surgery techniques and laser techniques. For that reason a group of 223 patients with hemangioma was retrospectively reviewed. For treatment, a pulsed dye laser (PDL) (Rhodamine G, wavelength 595 nm, pulsewidth between 0.45 and 40 ms, spot diameter 7 mm, energy density 9-11 J cm-2) was used and the results were compared with a control group treated with classical surgical therapy under general anesthesia. The curative effects, mainly number of sessions, appearance of scars, loss of pigment, and relapses were evaluated as a marker of successful treatment. From the results it was evident that the therapeutic effects of both systems are similar. The PDL was successful in all cases. The surgery patients had four relapses. Classical surgery is directly connected with the presence of scars, but the system is safe for larger hemangiomas. It was confirmed that the PDL had the optimal curative effect without scars for small lesions (approximately 10 mm). Surgical treatment under general anesthesia is better for large hemangiomas; the disadvantage is the presence of scars.

    Although adverse events in children treated with propranolol have proven rare, the appropriate methods of assessing cardiovascular risk and monitoring for toxicity when the medication is used for infantile hemangiomas remain unclear. We sought to analyze Holter monitor reports of otherwise healthy patients on propranolol for infantile hemangiomas to determine the incidence of sustained arrhythmias and to evaluate the utility of Holter monitoring in the outpatient setting. We retrospectively reviewed the charts of patients with infantile hemangioma who underwent 24-hour Holter monitoring after initiation or dose escalation of propranolol between 2011 and 2014. In all, 43 patients aged 1.8 to 36.2 months, with 44 Holter monitor reports, were included in the study. No sustained arrhythmias were revealed. The treatment plan was not altered in any patient based on the Holter monitor report. This was a retrospective study design. Our study suggests that Holter monitoring may be unnecessary in otherwise healthy patients with infantile hemangioma older than 12 weeks who are treated with propranolol in the outpatient setting.

    2006-01-01

    The purpose of this review was to inform all medical health care professionals about cuboid syndrome, which has been described as difficult to recognize and is commonly misdiagnosed, by explaining the etiology of this syndrome, its clinical diagnosis in relation to differential diagnoses, commonly administered treatment techniques, and patient outcomes. A comprehensive review of the relevant literature was conducted with MEDLINE, EBSCO, and PubMed (1960 - Present) using the key words cuboid, cuboid syndrome, foot anatomy, tarsal bones, manual therapy, and manipulation. Medical professionals must be aware that any lateral foot and ankle pain may be the result of cuboid syndrome. Once properly diagnosed, cuboid syndrome responds exceptionally well to conservative treatment involving specific cuboid manipulation techniques. Other methods of conservative treatment including therapeutic modalities, therapeutic exercises, padding, and low dye taping techniques are used as adjuncts in the treatment of this syndrome. Immediately after the manipulation is performed, the patient may note a decrease or a complete cessation of their symptoms. Occasionally, if the patient has had symptoms for a longer duration, several manipulations may be warranted throughout the course of time. Due to the fact radiographic imaging is of little value, the diagnosis is largely based on the patient’s history and a collection of signs and symptoms associated with the condition. Additionally, an understanding of the etiology behind this syndrome is essential, aiding the clinician in the diagnosis and treatment of this syndrome. After the correct diagnosis is made and a proper treatment regimen is utilized, the prognosis is excellent. Key Points Define the poorly understood condition of cuboid syndrome. Provide an understanding of the anatomical structures involved. Provide an explanation as to the cause of this syndrome. Demonstrate ways to evaluate by making a differential diagnosis. To inform

    EPA Pesticide Factsheets

    Following advice from the SAB Council, when estimating the economic value of reductions in air pollution-related mortality and morbidity risk, EPA accounts for the effect of personal income on the willingness to pay to reduce the risk of adverse health outcomes. These income growth adjustment factors are calculated using a combination of income elasticity estimates and income growth projections, both of which have remained essentially unchanged since 1999. These income elasticity estimates vary according to the severity of illness. EPA recently received advice from the SAB regarding the range of income elasticities to apply as well as the research standards to use when selecting income elasticity estimates. Following this advice, EPA consulted with a contractor to update its income elasticity and income growth projections, and generate new income growth adjustment factors. The SAB would evaluate the income elasticity estimates identified in the EPA-provided literature review, determining the extent to which these estimates are appropriate to use in human health benefits assessments.

    The occurrence of lactation is a rare complication of breast plastic surgery. During the course of his practice, the plastic surgeon will probably encounter this complication. The goal of this article is to carry out a literature review of all published galactorrhea and/or galactocele cases following a breast-reduction or a breast-augmentation, representing a total of 34 cases reported in 21 articles. The physiopathology of this complication is linked to an inappropriate secretion of prolactin in a surgical context. The factors favoring this complication would be the number of pregnancies, a history of recent and extensive nursing, and the intake of certain medicines such as an oestro-progestative pill. The main symptom of this complication is the occurrence of a uni- or bilateral galactorrhea, on average 12.6 days after the surgery. The main differential diagnosis is a postoperative infection. The explorations presented a hyperprolactinemia in 69% of cases. No biological inflammatory syndrome was reported. A fluid collection evoking a galactocele was visible on the ultrasound in 65% of cases. One case of prolactin-secreting pituitary adenoma was reported. Depending on the case, the treatment varied from a simple surveillance to the association of a dopamine agonist, an antibiotic therapy, and a surgical revision. A diagnostic and therapeutic management strategy is proposed.

  4. Broadening the perspective of pica: literature review.

    PubMed Central

    Lacey, E P

    1990-01-01

    Pica is an eating disorder that is manifested by a craving for oral ingestion of a given substance that is unusual in kind and or quantity. It is a long-standing practice that has far reaching implications for prevention and treatment--implications for public health as well as clinical personnel who work in settings where they have the potential for influencing health knowledge, attitudes, and behaviors of their patients. Pica practices also challenge researchers and social scientists whose work encompass development and refinement of models related to nutritional deficiencies. The body of literature on pica is so fragmented that it is difficult to find a precise summary of the knowns and unknowns about the condition. There is little consistency in defining pica, classifying substances ingested, identifying key characteristics of practicers, recommending treatment, or in projecting outcomes. This review presents a framework for understanding pica as a general practice, summarizes divergent reported hypotheses and conclusions, and illustrates that there is a need for more comprehensive studies of prevalence and incidence and use of deductive as well as inductive research processes.

    The literature on intersucking in cattle is reviewed. The following features are described: incidence, moments of appearance, relationship between herd mates, environmental factors (housing system, size of herd, area per animal, feeding places available, feed ration, nutrient deficiencies, housing and feeding practices during the rearing period), animal factors (genetic predisposition, social bonds, imitation), consequences (pathological changes, milk loss), and forms of symptomatic treatment (mechanical devices, surgery). It is concluded that rearing methods (bucket feeding of milk, early group housing) and genetic predisposition are likely to be the most important factors in the aetiology of intersucking in mature dairy cattle. As methods of symptomatic treatment are not successful in every case and are subject to ethical dispute, it is advisable not to treat intersucking cattle regardless of the symptomatic approach. This is the more important because there is clear evidence of genetic predisposition. The mode of inheritance is still unknown, but is likely to act through sucking motivation or drive at an early age. In problem herds more attention should be paid to rearing methods and selection of (A.I.) bulls. There also is a need for further research into the aetiology, particularly by longitudinal studies in which a large number of animals are studied from birth to first lactation.

    Phosphate ores contain elevated levels of natural radioactivity, some of which is released to the environment during processing or use of solid byproducts. The effect of radionuclides from Idaho phosphate processing operations on the local communities has been the subject of much research and study. The literature is reviewed in this report. Two primary radionuclide pathways to the environment have been studied in detail: (1) airborne release of volatile radionuclides, primarily /sup 210/Po, from calciner stacks at the two elemental phosphorus plants; and (2) use of byproduct slag as an aggregate for construction in Soda Springs and Pocatello. Despite the research, there is still no clear understanding of the population dose from radionuclide emissions, effluents, and solid wastes from phosphate processing plants. Two other potential radionuclide pathways to the environment have been identified: radon exhalation from phosphogypsum and ore piles and contamination of surface and ground waters. Recommendations on further study needed to develop a data base for a complete risk assssment are given in the report.

    With the amazing increasing in number of participants, rock climbing has become a popular sport in the last decade. A growing number of participants, with different skill level, inevitably leads to an increased number of injuries related to this practice. The kind of lesions that can be observed in rock-climbers is very specific and often involves the hand. For this reason is very important for any hand surgeon that is exposed to sport injuries to know which and the most common injuries related to this sport and which are the basic principles for the treatment of those. The aim of this article is to review the literature that has been published in the last ten year in this topic. On the NCBI database 22 articles where found that where related to rock climbing lesion affecting the hand or the whole body. Differences where found according to kind of rock climbing activity that was analyzed, alpine climb leads to more serious injuries, often affecting the lower limb, while in sport and recreational rock climbing the upper limb and the hand are definitely the most affected parts. Flexor pulley lesions, followed by fractures and strains are the most common lesions affecting the hand that are related to this practice.

    The purpose of this article is to review the nursing literature related to professional boundary violations in nursing. A search was conducted using CINAHL, MEDLINE, Ebscohost, and NCSBN. The key words searched were professional boundaries, boundary violation, boundary crossings, nurse, home health nurses, and home nursing. The search returned over 40 publications related specifically to boundary violations and nursing although only four of them are published research studies and one as a dissertation. Seven common characteristics emerged from the nonresearch nursing articles on professional boundaries: (1) Dual relations/role reversal, (2) Gifts and money, (3) Excessive self-disclosure, (4) Secretive behavior, (5) Excessive attention/overinvolvement, (6) Sexual behavior, and (7) Social media. Additional nursing research is greatly needed in the area of professional boundaries. The nurse-patient relationship should always be maintained for the benefit of the patient and not the personal gain of the nurse. Ongoing education in nursing practice regarding professional boundaries is needed. Nurses need to be mindful of state practice acts, codes of conduct, and employer policies.

    Leishmaniasis is a vector-borne protozoan infection whose clinical spectrum ranges from asymptomatic infection to fatal visceral leishmaniasis. Over the last decades, an increase in imported leishmaniasis cases in developed, non-endemic countries, have been pointed-out from a review of the international literature. Among the possible causes are increasing international tourism, influx of immigrants from endemic regions and military operations. The main area for the acquisition of cutaneous leishmaniasis, especially for adventure travelers on long-term trips in highly-endemic forested areas, is represented from South America, whereas popular Mediterranean destinations are emerging as the main areas to acquire visceral variant. Leishmaniasis should be considered in the diagnostic assessment of patients presenting with a compatible clinical syndrome and a history of travel to an endemic area, even if this occurred several months or years before. Adventure travelers, researchers, military personnel, and other groups of travelers likely to be exposed to sand flies in endemic areas, should receive counseling regarding leishmaniasis and appropriate protective measures.

    Djenkolism is an uncommon but important cause of acute kidney injury. It sporadically occurs after an ingestion of the djenkol bean (Archidendron pauciflorum), which is native to Southeast Asia. The clinical features defining djenkolism include: spasmodic suprapubic and/or flank pain; urinary obstruction; and acute kidney injury. The precise pathogenesis of acute kidney injury following djenkol ingestion remains unknown. However, it is proposed that an interaction between the characteristics of the ingested beans and the host factors causes hypersaturation of djenkolic acid crystals within the urinary system, resulting in subsequent obstructive nephropathy with sludge, stones, or possible spasms. We report a case of djenkolism from our rural clinic in Borneo, Indonesia. Our systematic literature review identified 96 reported cases of djenkolism. The majority of patients recovered with hydration, bicarbonate therapy, and pain medication. Three patients required surgical intervention; one patient required ureteral stenting for the obstructing djenkolic acid stones. Four of the 96 reported patients died from acute kidney failure. We stress the importance of awareness of djenkolism to guide medical practitioners in the treatment of this rare disease in resource-poor areas in Southeast Asia.

    The biochemical profile of classic primary hyperparathyroidism (pHPT) consists of both elevated calcium and parathyroid hormone levels. The standard of care is parathyroidectomy unless prohibited by medical comorbidities. Because more patients are undergoing routine bone density evaluation and neck imaging studies for other purposes, there is a subset of people identified with a biochemically mild form of the pHPT that expresses itself as either elevated calcium or parathyroid hormone levels. These patients often do not fall into the criteria for operation based on the National Institutes of Health consensus guidelines, and they can present a challenge of diagnosis and management. The purpose of this paper is to review the available literature on mild pHPT in an effort to better characterize this patient population and to determine whether patients benefit from parathyroidectomy. Evidence suggests that there are patients with mild pHPT who have overt symptoms that are found to improve after parathyroidectomy. There is also a group of patients with biochemically mild pHPT who are found to progress to classic pHPT over time; however, it is not predictable which group of patients this will be. Early intervention for this group with mild pHPT may prevent progression of bone, psychiatric, and renal complications, and parathyroidectomy has proven safe in appropriately selected patients at high volume centers.

    The objective of this first literature review, in this area, is to unveil the current status of knowledge on superstition in sport. Its outcome reveals that superstitious behaviors vary with the type of sport, athletic level, as well as athletic role. In agreement with past theories, they increase with the level of challenge, as reflected by the importance of the competition, as well as with the level of uncertainty. Cultural factors, in conjunction with the education level, as well as gender, have a strong influence on superstitious behaviors in sports. Based on current thoughts, religiosity and superstition are different psychological constructs used as psychological aids by several athletes. Personality factors appear to mediate the manifestation of the behavior. Elite athletes are clearly more superstitious than non-elite athletes, An interaction between athletic skill and task-difficulty emerges to be another strong predictor of superstition in sport. It is evident that a set of complex personal and situational factors interact in the manifestation of superstitious behavior in sport that is used for the regulation of emotions in a quest for optimal performance. It is concluded that the objective benefits (i.e., success) of superstition in sport may be ascribed to the placebo effect that yields an increased sense of control and mental reassurance in unpredictable contest situations. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

  13. Rothia mucilaginosa pneumonia: a literature review.

    2015-03-01

    Rothia mucilaginosa, a gram-positive coccus member of the family Micrococcaceae, is considered part of the normal microflora of the human mouth and the upper respiratory tract. Although this organism is believed to be of low virulence, it is increasingly recognized as an opportunistic pathogen mostly affecting immunocompromised hosts. The medical literature was reviewed and we found 19 published cases of R. mucilaginosa pneumonia. We also report on a case of pneumonia attributed to this microorganism in a patient with chronic obstructive pulmonary disease (COPD). From January 1970 to August 2014, a total of 20 patients with R. mucilaginosa pneumonia were studied. Patients with haematologic malignancies (7/20), profoundly neutropenic with central line catheters (7/20) are at higher risk of developing the infection, while immunocompetent hosts with impaired pulmonary defences are less frequently affected (4/20). Beta-lactams or vancomycin alone or in combination with other antibiotics have been successfully used for the treatment of R. mucilaginosa pneumonia. The outcome was favourable in 18 cases. Only one fatality was attributed to the infection. R. mucilaginosa should be considered in the diagnosis of pneumonia in both immunocompromised and immunocompetent hosts. Early diagnosis and timely administration of appropriate antibiotic treatment are necessary for cure.

  14. Congenital psoriasis: case report and literature review.

    Lehman, Julia S; Rahil, Anudeep K

    2008-01-01

    While childhood psoriasis is fairly common, congenital psoriasis appears to be rare and has not been well characterized. We present a patient with histologically confirmed congenital psoriasis. By reviewing the literature, we aim to both define this disease and compare it to infantile and childhood psoriasis. Electronic searches found articles reporting patients with biopsy-proven congenital psoriasis. We recorded clinical features, such as family history, anatomic involvement, and disease severity. We compared these data with previous descriptions of infantile and childhood psoriasis. We included nine patients with congenital psoriasis in our analysis. No patient had a first-degree family history of psoriasis. While the face, scalp, chest, and trunk were frequently involved, the buttocks generally were spared. Several patients had persistent disease despite therapy. In this series, congenital psoriasis differed from infantile and childhood psoriasis in several respects. Specifically, congenital psoriasis was associated with a lower prevalence of relevant family history, which could increase over time, and a different pattern of anatomic involvement, which may reflect exposure to age-associated environmental factors. Although several patients with congenital psoriasis had severe disease, this likely represents publication bias. Additional reports of congenital psoriasis with extended follow-up are needed to better characterize this condition.

  15. Income Elasticity Literature Review | Science Inventory | US ...

    EPA Pesticide Factsheets

    Following advice from the SAB Council, when estimating the economic value of reductions in air pollution-related mortality and morbidity risk, EPA accounts for the effect of personal income on the willingness to pay to reduce the risk of adverse health outcomes. These income growth adjustment factors are calculated using a combination of income elasticity estimates and income growth projections, both of which have remained essentially unchanged since 1999. These income elasticity estimates vary according to the severity of illness. EPA recently received advice from the SAB regarding the range of income elasticities to apply as well as the research standards to use when selecting income elasticity estimates. Following this advice, EPA consulted with a contractor to update its income elasticity and income growth projections, and generate new income growth adjustment factors. The SAB would evaluate the income elasticity estimates identified in the EPA-provided literature review, determining the extent to which these estimates are appropriate to use in human health benefits assessments.

    2004-03-01

    Integral to the Advanced Fuel Cycle Initiative (AFCI) Program’s proposed closed nuclear fuel cycle, the fission products cesium and strontium in the dissolved spent nuclear fuel stream are to be separated and managed separately. A comprehensive literature survey is presented to identify cesium and strontium separation technologies that have the highest potential and to focus research and development efforts on these technologies. Removal of these high-heat-emitting fission products reduces the radiation fields in subsequent fuel cycle reprocessing streams and provides a significant short-term (100 yr) heat source reduction in the repository. This, along with separation of actinides, may provide a substantial future improvement in the amount of fuel that could be stored in a geologic repository. The survey and review of the candidate cesium and strontium separation technologies are presented herein. Because the AFCI program intends to manage cesium and strontium together, technologies that simultaneously separate both elements are of the greatest interest, relative to technologies that separate only one of the two elements.

    The concept of vulnerability is delimited by dynamic social and multigenerational processes involving at least three dimensions: exposure to risk trajectories, internal and external capabilities of reaction and possibilities of adaptation based on both the intensity of risk and the resilience of people. In order to identify and describe the synthetic indices of vulnerability, there was an integrative literature review. We consulted free access articles indexed in the following databases: BioMed, Bireme, PubMed, Reldalyc, SciELO and Web of Science; and we used controlled descriptors in English and Portuguese for all time slots available with selection and analysis of 47 studies that reported results of 23 synthetic indices of vulnerability. The results showed that the synthetic indices of vulnerability address four themes: social determinants of health; environmental and climatic conditions; family and course of life; territories and specific geographic areas. It was concluded that the definition of the components and indicators, as well as the methodologies adopted for the construction of synthetic indices need to be evaluated by means of the limitations and advantages of reporting the vulnerability through summary measures in policy formulation and decision-making aimed at human development.

  18. The utility of GLUT1 as a diagnostic marker in cutaneous vascular anomalies: A review of literature and recommendations for daily practice.

    To assess the utility of GLUT1 as an immunohistochemical marker in the diagnostics of cutaneous vascular anomalies. A systematic literature search was conducted for studies on GLUT1 staining patterns in cutaneous vascular lesions. Data was grouped according to the latest ISSVA classification for vascular anomalies. Vascular tumors: GLUT1 staining was positive in 368/386 (95%) of infantile hemangiomas. Congenital hemangiomas (16 cases) and kaposiform hemangioendotheliomas (62 cases) were all negative for GLUT1. Angiosarcomas were GLUT1 positive in 12/39 (31%) and epithelioid hemangioendotheliomas in 2/27 (7%) of cases. Vascular malformations: All vascular malformations (33 arteriovenous malformations, 16 capillary malformations, 64 lymphatic malformations, 54 venous malformations, 3 venous-lymphatic malformations and 3 capillary venous-lymphatic malformations) were negative for GLUT1 staining. Unclassified vascular anomalies: Angiokeratomas were GLUT1 positive in 1/15 (7%) and verrucous hemangiomas in 71/100 (71%) of cases. Microvenular hemangiomas were negative for GLUT1 in all 9 cases. GLUT1 can be used as an additional diagnostic tool in cutaneous vascular lesions. A negative GLUT1 stain renders a diagnosis of infantile hemangioma unlikely. A positive GLUT1 stain excludes vascular malformations and is suggestive of infantile hemangioma. One must be cautious, however, that the final diagnosis is made through interpretation of all clinical and diagnostic features, and not based on GLUT1 staining alone. Copyright © 2017 Elsevier GmbH.

    2006-01-01

    Little is known about the pathogenesis of infantile hemangiomas despite the fact that they are relatively common tumors. These benign neoplasms occur in as many as 1 in 10 births, and although rarely life threatening, hemangiomas can pose serious concerns to the cosmetic and psychosocial development of the afflicted child. Ulceration, scarring, and disfigurement are significant problems as are encroachment of the ear and eye, which can threaten hearing and vision. The precise mechanisms controlling the rapid growth observed in the first months of life and the spontaneous involution that follows throughout the course of years remain unknown. In this report we demonstrate the presence of large numbers of hematopoietic cells of the myeloid lineage in proliferating hemangiomas and propose a mechanism for the observed evolution of these lesions that is triggered by hypoxia and involves the participation of myeloid cells. We report the results of experiments using myeloid markers (CD83, CD32, CD14, CD15) that unexpectedly co-labeled hemangioma endothelial cells, providing new evidence that these cells are distinct from normal endothelium.

    Areas of blanched skin in children may be seen as an independent finding or in association with vascular birthmarks. We performed a retrospective chart review to identify and describe infants with areas of ventral midline blanching in the presence of segmental infantile hemangiomas. We identified nine full-term infants with partial or full segmental hemangiomas and areas of midline ventral blanching. Additional ventral wall defects were seen in five patients. Six had cardiac anomalies and six had intracranial anomalies. Five were diagnosed with definite PHACE (posterior fossa, hemangioma, arterial, cardiac, and eye abnormalities) syndrome and three had possible PHACE syndrome. Eight were complicated by ulceration. Treatment varied according to the case. Ventral blanching, even in the absence of overt midline defects, can be seen in infants with segmental hemangiomas at risk for PHACE syndrome. We hypothesize that midline blanching may represent a minor manifestation of a developmental ventral defect. © 2014 Wiley Periodicals, Inc.

  4. Hemangioma of the prostate - an unusual cause of lower urinary tract symptoms: Case report

    PubMed Central

    2011-01-01

    Background Hemangioma of the prostate gland is extremely rare and only a few cases have been reported. There have been several cases of hemangioma of posterior urethra, urinary bladder and periprostatic plexus in the literature, all presenting with hematuria or hematospermia. Diagnosis of prostatic hemangioma is difficult due to its rarity and unspecific symptoms such as hematuria, hematospermia or lower urinary tract symptoms. It cannot be detected by conventional examinations such as cystoscopy or standard rectal ultrasonography. Case presentation We present a case of prostatic hemangioma in an 84-year old male presenting with lower urinary tract symptoms. Bleeding has not been a feature in our case and diagnosis was not made until after operation. The patient was treated as a case of bladder neck outflow obstruction with transurethral resection of prostate gland and simultaneous bladder neck incisions. A period of self-catheterization was instituted due to postoperative urinary retention as the result of detrusor insufficiency. Conclusion Hemangioma of prostate gland is extremely rare and symptomatic prostatic hemangioma should be treated either by transurethral resection of prostate or laser evaporation. PMID:21486499

    Psychiatric disorders are consistent with the gene x environment model, and non-specific environmental factors such as childhood trauma, urbanity, and migration have been implicated. All of these factors have in common to dysregulate the biological pathways involved in response to stress. Stress is a well-known precipitating factor implicated in psychiatric disorders such as depression, bipolar disorder, anxiety, and possibly schizophrenia. More precisely, psychosocial stress induces dysregulation of the hypothalamic-pituitary-adrenal axis (HPA) and could modify neurotransmission, which raises the question of the involvement of stress-related biological changes in psychotic disorders. Indeed, the literature reveals dysregulation of the HPA axis in schizophrenia. This dysregulation seems to be present in the prodromal phases (UHR subjects for ultra-high risk) and early schizophrenia (FEP for first episode psychosis). Thus, and following the stress-vulnerability model, stress could act directly on psychotic onset and precipitate the transition of vulnerable subjects to a full-blown psychosis. The present paper reviews the literature on stress and onset of schizophrenia, with consideration for the causal role vs. associated role of HPA axis dysregulation in schizophrenia and the factors that influence it, in particular during prodromal and earlier phases. We also discuss different methods developed to measure stress in humans. We performed a bibliographic search using the keywords 'cortisol', 'glucocorticoid', 'HPA' with 'UHR', 'CHR', 'at-risk mental state', 'first episode psychosis', 'schizotypal', 'prodromal schizophrenia' in Medline, Web of Knowledge (WOS), and EBSCO completed by a screening of the references of the selected articles. Stress has been studied for many years in schizophrenia, either by subjective methods (questionnaires), or objective methods (standardized experimental protocols) with biological sampling and/or brain imaging methods.

    Hemangioma is the most common vascular tumor of infancy; presentation is often as cutaneous infantile hemangioma (IH). Cutaneous hemangioma is a clinical diagnosis. Most IHs follow a benign course, with complete involution without treatment in the majority of cases. Visceral hemangioma often involves the liver and manifests as a life-threatening disorder. Hepatic hemangiomas may be associated with high output cardiac failure, coagulopathy, and hepatomegaly which generally develop between 1 and 16 weeks of age. Mortality has been reportedly high without treatment. We report a rare case of a male infant with neonatal hemangiomatosis with diffuse peritoneal involvement, which mimicked a malignant-looking tumor on imaging, and discuss therapeutic options and efficacy. Propranolol is efficacious for IH but generally not useful for other forms of vascular hemangiomas, tumors, and malformations. In our case of neonatal peritoneal hemangiomatosis, propranolol appears to have halted the growth and possibly expedite the involution of the hemangiomatosis without other treatments.

    Today vertebral hemangioma is not completely understood entity, neither its pathogenesis nor optimal treatment is determined. Nowadays in majority of clinics in this country ineffective radiotherapy remains the first-line treatment. We analyzed results of treatment of 205 patients (286 lesions) with aggressive hemangiomas operated in Department of Neurosurgery of Military Medical Academy and Department of Nuclear Medicine of of Russian Scientific Center of Radiological and Surgical Technologies (Saint-Petersburg, Russia) since 1999 till 2009. Percutaneus vertebroplasty was performed in 167 lesions, radiotherapy was applied in 119 aggressive hemangiomas. Vertebroplasty is more effective for treatment of aggressive hemangiomas in comparison with radiotherapy. Signs of hemangiomas aggression, indications for surgery, and tactics of management were determined. Use of percutaneous vertebroplasty for treatment of aggressive hemangiomas resulted in fast recovery of the patients. This procedure is minimally invasive, it reduces hospital stay and duration of recovery.

    A new solvent system is being evaluated for use in the Modular Caustic-Side Solvent Extraction Unit (MCU) and in the Salt Waste Processing Facility (SWPF). The new system replaces the current dilute nitric acid strip solution with 0.01 M boric acid. This literature study is performed to determine if there is a potential for boric acid to crystallize in the lines with emphasis on the transfer lines to the Defense Waste Processing Facility. This report focuses on the aqueous phase chemistry of boric acid under conditions relevant to MCU and SWPF. Operating and transfer conditions examined for the purpose of this review include temperatures between 13 C (McLeskey, 2008) and 45 C (Fondeur, 2007) and concentrations from 0 to 3M in nitric acid as well as exposure of small amounts of entrained boric acid in the organic phase to the sodium hydroxide caustic wash stream. Experiments were also conducted to observe any chemical reactions and off-gas generation that could occur when 0.01 M boric acid solution mixes with 3 M nitric acid solution and vice versa. Based on the low concentration (0.01M) of boric acid in the MCU/SWPF strip acid and the moderate operating temperatures (13 C to 45 C), it is unlikely that crystallization of boric acid will occur in the acid strip solution under process or transfer conditions. Mixing experiments of boric and nitric acid show no measurable gas generation (< 1 cc of gas per liter of solution) under similar process conditions.

    Cryptococcosis is reported in adults and is often acquired immune deficiency syndrome (AIDS)-associated; however, its frequency in children is low. Based on the National Survey on Cryptococcosis conducted in Colombia, an epidemiological and clinical analysis was performed on cases of the disease observed in children less than 16 years old between 1993-2010. We found 41 affected children (2.6% prevalence) from the 1,578 surveys received. The country mean annual incidence rate was 0.017 cases/100,000 children under 16 years, while in Norte de Santander the incidence rate was 0.122 cases/100,000 (p < 0.0001). The average age of infected children was 8.4 and 58.5% were male. In 46.3% of cases, a risk factor was not identified, while 24.4% had AIDS. The most frequent clinical manifestations were headache (78.1%), fever (68.8%), nausea and vomiting (65.6%), confusion (50%) and meningeal signs (37.5%). Meningitis was the most frequent clinical presentation (87.8%). Amphotericin B was given to 93.5% of patients as an initial treatment. Positive microbiological identification was accomplished by India ink (94.7%), latex in cerebrospinal fluid (100%) and culture (89.5%). Out of 34 isolates studied, Cryptococcus neoformans var. grubii (VNI 85.3%, VNII 8.8%) was isolated in 94.1% of cases and Cryptococcus gattii (VGII) was isolated in 5.9% of cases. These data are complemented by a literature review, which overall suggests that cryptococcosis in children is an unusual event worldwide. PMID:25317708

  11. Microalgae harvesting and processing: a literature review

    Shelef, G.; Sukenik, A.; Green, M.

    1984-08-01

    The objective of this report is to present a discussion of the literature review performed on methods of harvesting microalgae. There is no single best method of harvesting microalgae. The choice of preferable harvesting technology depends on algae species, growth medium, algae production, end product, and production cost benefit. Algae size is an important factor since low-cost filtration procedures are presently applicable only for harvesting fairly large microalgae. Small microalgae should be flocculated into larger bodies that can be harvested by one of the methods mentioned above. However, the cells' mobility affects the flocculation process, and addition of nonresidual oxidants to stop the mobility should be considered to aid flocculation. The decision between sedimentation or flotation methods depends on the density difference between the algae cell and the growth medium. For oil-laden algae with low cell density, flotation technologies should be considered. Moreover, oxygen release from algae cells and oxygen supersaturation conditions in growth medium support the use of flotation methods. If high-quality algae are to be produced for human consumption, continuous harvesting by solid ejecting or nozzle-type disc centrifuges is recommended. These centrifuges can easily be cleaned and sterilized. They are suitable for all types of microalgae, but their high operating costs should be compared with the benefits from their use. Another basic criterion for selecting the suitable harvesting procedure is the final algae paste concentration required for the next process. Solids requirements up to 30% can be attained by established dewatering processes. For more concentrated solids, drying methods are required. The various systems for algae drying differ both in the extent of capital investment and the energy requirements. Selection of the drying method depends on the scale of operation and the use for which the dried product is intended.

    There is no uniform pretreatment cardiac evaluation for infants treated with oral propranolol, which is now the drug of choice for hemangiomas of infancy requiring systemic medical intervention. The aim of this study was to report and evaluate the findings of pretreatment cardiac evaluation. Data were reviewed for patients evaluated by a single hemangioma specialist and a single pediatric cardiologist prior to initiation of propranolol for infantile hemangioma. Cardiac evaluation included a complete echocardiogram. From July 2009 through January 2013, 239 consecutive patients 12 months of age or younger (median 2.7 months) were screened. No patients had cardiac contraindications to propranolol. However, 50 patients (21%) had an abnormal echocardiogram: 39 atrial septal defects (5 associated with right heart enlargement), 6 ventricular septal defects, 2 patent ductus arteriosus, 1 aortic coarctation, 1 pulmonary valve stenosis, and 1 aberrant subclavian artery. Overall, 69 patients had an audible heart murmur, 44 of which were not associated with pathologic findings on echocardiogram. All patients with a ventricular septal defect and 16 of 39 with an atrial septal defect had a murmur. Two of seven patients with PHACE syndrome had cardiac anomalies. None of the findings precluded the use of propranolol. Assisted reproductive technologies were used in 18% of pregnancies, including in vitro fertilization in 12%. Cardiac contraindications to propranolol treatment are uncommon in patients with infantile hemangioma. However, anatomic abnormalities were more common than reported in the general population. Further study is necessary to determine whether there is a pathogenic relationship between cardiac defects and nonsyndromic infantile hemangioma. © 2014 Wiley Periodicals, Inc.

    Hepatic cavernous hemangiomas are usually small and asymptomatic. They are usually discovered incidentally and only a few require treatment. However, giant hemangiomas may cause symptoms,which are indications for treatment. We describe four cases of symptomatic giant hepatic hemangiomas successfully treated with transcatheter arterial embolization, performed with polyvinyl alcohol particles. There were no complications. Follow-up with clinical and imaging examinations showed disappearance of symptoms and decrease in size of lesions.

    Vertebral hemangiomas are common lesions and usually considered benign. A rare subset of them, however, are characterized by extra-osseous extension, bone expansion, disturbance of blood flow, and occasionally compression fractures and thereby referred to as aggressive hemangiomas. We present a case of a 67-year-old woman with progressive paraplegia and an infiltrative mass of T4 vertebra causing mass effect on the spinal cord. Multiple conventional imaging modalities were utilized to suggest the diagnosis of aggressive hemangioma. Final pathologic diagnosis after decompressive surgery confirmed the diagnosis of an osseous hemangioma.

  15. Non-celiac gluten sensitivity: literature review.

    PubMed

    2014-01-01

    A significant percentage of the general population report problems caused by wheat and/or gluten ingestion, even though they do not have celiac disease (CD) or wheat allergy (WA), because they test negative both for CD-specific serology and histopathology and for immunoglobulin E (IgE)-mediated assays. Most patients report both gastrointestinal and nongastrointestinal symptoms, and all report improvement of symptoms on a gluten-free diet. This clinical condition has been named non-celiac gluten sensitivity (NCGS). We attempt to define the current pathogenic, clinical, and diagnostic criteria of this "new" disease, to provide a practical view that might be useful to evaluate, diagnose, and manage NCGS patients. We reviewed the international literature through PubMed and Medline, using the search terms "wheat (hyper)sensitivity," "wheat allergy," "wheat intolerance," "gluten (hyper)sensitivity," and "gluten intolerance," and we discuss current knowledge about NCGS. It has been demonstrated that patients suffering from NCGS are a heterogeneous group, composed of several subgroups, each characterized by different pathogenesis, clinical history, and, probably, clinical course. NCGS diagnosis can be reached only by excluding CD and WA. Recent evidence shows that a personal history of food allergy in infancy, coexistent atopy, positive for immunoglobulin G (IgG) antigliadin antibodies and flow cytometric basophil activation test, with wheat and duodenal and/or ileum-colon intraepithelial and lamina propria eosinophil counts, could be useful to identify NCGS patients. Future research should aim to identify reliable biomarkers for NCGS diagnosis and to better define the different NCGS subgroups. Key teaching points: • Most patients report both gastrointestinal and nongastrointestinal symptoms, and all agree that there is an improvement of symptoms on a gluten-free diet. • NCGS diagnosis can be reached only by excluding celiac disease and wheat allergy. • Patients

    AIM: To investigate whether systemic lupus erythematosus (SLE) is associated with benign focal liver lesions and vascular liver diseases, since these have been occasionally reported in SLE patients. METHODS: Thirty-five consecutive adult patients with SLE and 35 age- and sex-matched healthy controls were evaluated. Hepatic and portal vein patency and presence of focal liver lesions were studied by colour-Doppler ultrasound, computerized tomography and magnetic resonance were used to refine the diagnosis, clinical data of SLE patients were reviewed. RESULTS: Benign hepatic lesions were common in SLE patients (54% vs 14% controls, P < 0.0001), with hemangioma being the most commonly observed lesion in the two groups. SLE was associated with the presence of single hemangioma [odds ratios (OR) 5.05; 95% confidence interval (CI) 1.91-13.38] and multiple hemangiomas (OR 4.13; 95% CI 1.03-16.55). Multiple hemangiomas were associated with a longer duration of SLE (9.9 ± 6.5 vs 5.5 ± 6.4 years; P = 0.04). Imaging prior to SLE onset was available in 9 patients with SLE and hemangioma, showing absence of lesions in 7/9. The clinical data of our patients suggest that SLE possibly plays a role in the development of hemangioma. In addition, a Budd-Chiari syndrome associated with nodular regenerative hyperplasia (NRH), and a NRH associated with hepatic hemangioma were observed, both in patients hospitalized for abdominal symptoms, suggesting that vascular liver diseases should be specifically investigated in this population. CONCLUSION: SLE is associated with 5-fold increased odds of liver hemangiomas, suggesting that these might be considered among the hepatic manifestations of SLE. PMID:22110281

    AIM: To compare safety and therapeutic efficacy of laparoscopic radiofrequency (RF) ablation vs computed tomography (CT)-guided RF ablation for large hepatic hemangiomas abutting the diaphragm. METHODS: We retrospectively reviewed our sequential experience of treating 51 large hepatic hemangiomas abutting the diaphragm in 51 patients by CT-guided or laparoscopic RF ablation due to either the presence of symptoms and/or the enlargement of hemangioma. Altogether, 24 hemangiomas were ablated via a CT-guided percutaneous approach (CT-guided ablation group), and 27 hemangiomas were treated via a laparoscopic approach (laparoscopic ablation group). RESULTS: The mean diameter of the 51 hemangiomas was 9.6 ± 1.8 cm (range, 6.0-12.0 cm). There was no difference in the diameter of hemangiomas between the two groups (P > 0.05). RF ablation was performed successfully in all patients. There was no difference in ablation times between groups (P > 0.05). There were 23 thoracic complications in 17 patients: 15 (62.5%, 15/24) in the CT-guided ablation group and 2 (7.4%, 2/27) in the laparoscopic ablation group (P < 0.05). According to the Dindo-Clavien classification, two complications (pleural effusion and diaphragmatic rupture grade III) were major in two patients. All others were minor (grade I). Both major complications occurred in the CT-guided ablation group. The minor complications were treated successfully with conservative measures, and the two major complications underwent treatment by chest tube drainage and thoracoscopic surgery, respectively. Complete ablation was achieved in 91.7% (22/24) and 96.3% (26/27) in the CT-guided and the laparoscopic ablation groups, respectively (P > 0.05). CONCLUSION: Laparoscopic RF ablation therapy should be used as the first-line treatment option for large hepatic hemangiomas abutting the diaphragm. It avoids thermal injury to the diaphragm and reduces thoracic complications. PMID:26019459

    Congenital vascular tumors of the skin have been described in people and a few animals, but unlike infantile hemangiomas in children, spontaneous regression has not been described in animals. A 2-day-old male Belgian Blue cross calf was presented for multiple congenital cutaneous masses that were soft, alopecic, and hyperemic; the calf had no other apparent abnormalities. Two weeks later, one mass had regressed. Surgical excision of one of the remaining masses was performed; histopathologic and immunohistochemical findings were considered diagnostic for epithelioid hemangioma. Eight months following initial presentation, all the masses had regressed spontaneously. This constitutes the first account in the veterinary literature of spontaneous regression in a congenital vascular tumor.

    Cavernous hemangioma of the larynx is an uncommon, difficult-to-diagnose vascular tumor for which there is no significant imaging literature to date. The possibility of improved diagnosis through RBC scanning might obviate injudicious biopsy and potential hemorrhage within the airway. Utilizing the radionuclide RBC scan, which labels the patient's own RBCs initially with cold pyrophosphate, and subsequently with technetium 99m as pertechnetate, we have identified successfully four patients with cavernous hemangioma of the larynx. All presented with a supraglottic mass involving at least the aryepiglottic fold and arytenoid region unilaterally. This report describes our satisfactory diagnostic imaging experience with the radionuclide RBC scan and suggests both its imaging specificity and its role in the management of this lesion.

    Vascular anomalies are a heterogeneous group of congenital blood vessel disorders more typically referred to as birthmarks. Subcategorized into vascular tumors and malformations, each anomaly is characterized by specific morphology, pathophysiology, clinical behavior, and management approach. Hemangiomas are the most common vascular tumor. Lymphatic, capillary, venous, and arteriovenous malformations make up the majority of vascular malformations. This paper reviews current theory and practice in the etiology, diagnosis, and treatment of these more common vascular anomalies. PMID:22611412

    Aim. Cavernous hemangioma-like Kaposi sarcoma is a rare morphologic type of Kaposi sarcoma. So far there are no cases in the literature defining the histological features of this morphologic spectrum in detail. In this study we presented two classical-type cutaneous Kaposi sarcoma cases with histologic findings resembling cavernous hemangioma in company with clinical and histopathological data. Cases. One hundred and eighty-five classical-type cutaneous Kaposi sarcoma lesions in 79 patients were assessed retrospectively in terms of histopathological features. Findings of two cases showing features of cavernous hemangioma-like Kaposi sarcoma whose clinical data could be accessed were presented in accompany with the literature data. Both cases were detected to have bluish-purple, protruded, irregularly bordered cutaneous lesions. Histopathological examination revealed a lesion formed by cavernous hemangioma-like vascular structures organized in a lobular pattern that became dilated and filled with blood. Typical histological findings of early-stage KS, consisting of mononuclear inflammation, extravasated erythrocytes, and a few immature vascular structures in superficial dermis, were observed. All cases were serologically HIV-1 negative. A positive reaction with HHV-8, CD31, CD34, and D2-40 monoclonal antibodies was identified at both cavernous hemangioma-like areas and in immature vascular structures. Results. Cavernous hemangioma-like Kaposi sarcoma is a rare Kaposi sarcoma variant presenting with diagnostic challenges, that may be confused with hemangioma. As characteristic morphological features may not be observed in every case, it is important for diagnostic purposes to show immunohistochemical HHV-8 positivity in this variant.

    2016-01-01

    Pyogenic granuloma (PG), more accurately known as lobular capillary hemangioma, is a benign vascular tumor that usually occurs in the skin or oral mucosa. This lesion is rarely reported in the gastrointestinal tract but is known to bleed if not resected. We herein describe a case series with the clinical, endoscopic, and histologic findings of four cases of gastrointestinal PG at our institution. In addition, we provide a review of the literature and summation of all reported cases of PG specific to the gastrointestinal tract. Based on our experience, we suggest that the actual incidence of gastrointestinal PG may in fact be higher than reported because PG can be unrecognized or improperly diagnosed. It is important for the clinician to properly recognize this lesion as a source of anemia and its propensity to bleed during biopsy or resection. PMID:27403353

    POEMS syndrome is a paraneoplastic manifestation associated with hematopoietic disorders such as multiple myeloma and Castleman disease. POEMS is an acronym for the main clinical features of the syndrome, namely, Polyneuropathy, Organomegaly, Endocrinopathy, M protein, and Skin abnormalities. Glomeruloid hemangiomas are considered to be a specific clinical marker of POEMS syndrome. However, while they are not pathognomonic, their presence should raise suspicion of this syndrome or alert clinicians to its possible future development, as these lesions can appear years before the onset of the syndrome. We report the cases of 2 women with plasma cell dyscrasias and sudden onset of lesions with a vascular appearance and histologic findings consistent with glomeruloid hemangioma. Recognition of this vascular tumor is important for the early diagnosis of POEMS syndrome. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    The group of passive prostheses consists of prosthetic hands and prosthetic tools. These can either be static or adjustable. Limited research and development on passive prostheses has been performed although many people use these prosthesis types. Although some publications describe passive prostheses, no recent review of the peer-reviewed literature on passive prostheses is available. Review the peer-reviewed literature on passive prostheses for replacement of the hand. Literature review. Four electronic databases were searched using a Boolean combination of relevant keywords. English-language articles relevant to the objective were selected. In all, 38 papers were included in the review. Publications on passive prosthetic hands describe their users, usage, functionality, and problems in activities of daily living. Publications on prosthetic tools mostly focus on sport, recreation, and vehicle driving. Passive hand prostheses receive little attention in prosthetic research and literature. Yet one out of three people with a limb deficiency uses this type of prosthesis. Literature indicates that passive prostheses can be improved on pulling and grasping functions. In the literature, ambiguous names are used for different types of passive prostheses. This causes confusion. We present a new and clear classification of passive prostheses. Clinical relevance This review provides information on the users of passive prosthetic hands and tools, their usage and the functionality. Passive prostheses receive very little attention and low appreciation in literature. Passive prosthetic hands and tools show to be useful to many unilateral amputees and should receive more attention and higher acceptance.

  9. [Spasmodic torticollis and vertebral hemangioma].

    PubMed

    Durán, E; Chacón, J R

    Spasmodic torticollis in young patients should give rise to a clinical suspicion that this is secondary to another primary disorder. Therefore a series of diagnostic tests should be carried out before it is labelled as idiopathic. The patient was a thirty year old man who had had difficulty in writing with his right hand since childhood. At the age of 20 years he was diagnosed as having writer's cramp and idiopathic spasmodic torticollis. On general physical examination no abnormalities were found. On neurological examination he had: absence of reflexes of both arms, limited but painless rotation of the neck towards the left and hypertrophy of the left trapezius muscle. Laboratory, neurophysiological and neuroimaging investigations seeking a secondary cause for the torticollis were all normal. There were no Keyser-Fleischer rings. Chest X-ray showed, dorsal scoliosis with convexity to the left. CAT and MR of the spine showed a hemangioma in the body of T1. On arteriography of the supra-aortic and vertebral trunks a hemangioma was found at T1 which received contrast material via a branch of the right thyro-bi-cervico-scapular trunk. Various treatments were tried (diazepam, Botox, Dysport, tetrabenazine, baclofen, etc.) with no improvement. A definite diagnosis of secondary torticollis could not be made since the hemangioma was supplied by a very narrow vascular pedicle, so embolization was contraindicated. Cervical spinal cord alterations may cause focal dystonia due to increased excitability of the spinal motor neurone, due to dysfunction of the disinhibitory descending reciprocal paths.

    A 61-year-old female patient presented with diffuse pain in the dorsal region of the back of 3 months duration. The magnetic resonance imaging showed an extramedullary, extradural space occupative lesion on the right side of the spinal canal from D5 to D7 vertebral levels. The mass was well marginated and there was no bone involvement. Compression of the adjacent thecal sac was observed, with displacement to the left side. Radiological differential diagnosis included nerve sheath tumor and meningioma. The patient underwent D6 hemilaminectomy under general anesthesia. Intraoperatively, the tumor was purely extradural in location with mild extension into the right foramina. No attachment to the nerves or dura was found. Total excision of the extradural compressing mass was possible as there were preserved planes all around. Histopathology revealed cavernous hemangioma. As illustrated in our case, purely epidural hemangiomas, although uncommon, ought to be considered in the differential diagnosis of spinal epidural soft tissue masses. Findings that may help to differentiate this lesion from the ubiquitous disk prolapse, more common meningiomas and nerve sheath tumors are its ovoid shape, uniform T2 hyperintense signal and lack of anatomic connection with the neighboring intervertebral disk or the exiting nerve root. Entirely extradural lesions with no bone involvement are rare and represent about 12% of all intraspinal hemangiomas.

    PubMed

    Burke, F J Trevor

    2012-05-01

    Ozone, either in gaseous form or as ozonated water, has been available for use as a treatment for dental caries for a decade. This paper reviews the literature on the subject by examining the findings of publications in the peer review literature. Eighteen papers were identified by a literature search. From the review of these, it was concluded that, while some laboratory studies and some short duration clinical studies have suggested that ozone may be effective in the treatment of root caries or killing of oral micro-organisms, the clinical evidence for the use of ozone in treatment of caries is not compelling.

Methods A PubMed search was performed using the terms pregnancy and chiropractic. Sources were cross-referenced to obtain further articles and research information after reviewing the articles obtained through the search. Results Thirty-three references were used for this review. The current literature reports favorable results on the use of chiropractic care throughout pregnancy. Conclusions Chiropractic evaluation and treatment during pregnancy may be considered a safe and effective means of treating common musculoskeletal symptoms that affect pregnant patients. The scarcity of published literature warrants further research. PMID:19674697

  5. Quiescent Volcano-Chest Wall Hemangioma.

    Saldanha, Elroy; Martis, John J S; Kumar, B Vinod; D'Cunha, Rithesh J; Vijin, V

    2017-08-01

    Chest wall hemangiomas are rare tumors that may originate within the soft tissue or from the ribs. Intramuscular hemangioma is infrequent, representing less than 1 % of all hemangiomas, and the localization in the chest wall is even less frequent. They are typically cutaneous in location, large, and poorly circumscribed and can be locally destructive. We present a case of a 34-year-old lady presented with firm lump 3 × 3 cm in left upper and inner quadrant of left breast well defined borders, non-pulsatile and restricted mobility. Sono-mammogram was suggestive of ill-defined lesion at 10 o'clock position. CT chest was conclusive of chest wall hemangioma. The patient underwent excision of the lump. HPE was suggestive of cavernous hemangioma. Cavernous hemangioma typically manifest at birth or before the age of 30 years. CT is more sensitive than plain radiography in detecting phleboliths, which are present in approximately 30 % of cavernous hemangiomas. Surgical excision would be treatment of choice. In this case, the site of the lesion was in the breast clinically mimicking that of a fibroadenoma which warrants hemangioma as a differential diagnosis.

    A maxillary sinus hemangioma was detected as an incidental finding during magnetic resonance imaging of the head. The CT findings are more characteristic for the diagnosis of this lesion. Preoperative diagnosis of maxillary sinus hemangioma is important since these lesions can frequently cause a large amount of hemorrhage during surgery.

    2016-04-01

    Recently, anti-vascular endothelial growth factor (anti-VEGF) agents have been described in the literature as a valid treatment option for symptomatic liver hemangiomas, but only limited evidence supports this notion. The purpose of this study was to elucidate whether or not the administration of anti-VEGF agents can reliably achieve a size reduction in liver hemangiomas. We examined patients with incidental hemangiomas who received anti-angiogenic agents for the treatment of other malignancies. Our study population consisted of 17 colorectal cancer patients and one lung cancer patient carrying 21 hemangiomas who received bevacizumab, and seven renal cell carcinoma patients carrying nine hepatic hemangiomas who received sunitinib. We have measured the liver hemangioma volume on both the pre-treatment and post-treatment computed tomography images and then calculated the volume alteration rates. No statistically significant difference (P = 0.365) in the volume of the liver hemangiomas was observed before (1.1-168.8 cm(3); mean ± SD 19.8 ± 39.7 cm(3)) or after (1.2-163.6 cm(3); 19.3 ± 38.0 cm(3)) bevacizumab treatment. The volume reduction rate ranged from -35.0 to 11.2 % (mean ± SD -1.3 ± 10.8 %). The sunitinib treatment group also showed no statistically significant difference (P = 0.889) in hemangioma volume before (1.2-6.5 cm(3); 3.0 ± 1.8 cm(3)) or after (1.2-6.0 cm(3); 3.0-1.7 cm(3)) treatment. The volume reduction rate ranged from -13.3 to 7.7 % (median: mean ± SD -2.5 ± 6.6 %). We did not observe liver hemangioma shrinkage after bevacizumab or sunitinib treatment. Our data do not support the application of anti-VEGF agents for the treatment of hepatic hemangiomas.

    Integrative and systematic reviews present synthesized research. Scholars have called for increased rigor and reporting in reviews. The purpose of this methodological review was to describe the characteristics of nurse-led reviews. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines directed the review process. Many reviews did not clearly report the search strategy used and methods for data extraction and quality appraisal, indicating that there has not been an increase in rigor. Authors of reviews are encouraged to report sufficient methodological details, so peer reviewers and consumers can determine whether the methods were rigorous enough to contribute meaningful results.

  11. Signaling pathways in the development of infantile hemangioma

    PubMed Central

    2014-01-01

    Infantile hemangioma (IH), which is the most common tumor in infants, is a benign vascular neoplasm resulting from the abnormal proliferation of endothelial cells and pericytes. For nearly a century, researchers have noted that IH exhibits diverse and often dramatic clinical behaviors. On the one hand, most lesions pose no threat or potential for complication and resolve spontaneously without concern in most children with IH. On the other hand, approximately 10% of IHs are destructive, disfiguring and even vision- or life-threatening. Recent studies have provided some insight into the pathogenesis of these vascular tumors, leading to a better understanding of the biological features of IH and, in particular, indicating that during hemangioma neovascularization, two main pathogenic mechanisms prevail, angiogenesis and vasculogenesis. Both mechanisms have been linked to alterations in several important cellular signaling pathways. These pathways are of interest from a therapeutic perspective because targeting them may help to reverse, delay or prevent hemangioma neovascularization. In this review, we explore some of the major pathways implicated in IH, including the VEGF/VEGFR, Notch, β-adrenergic, Tie2/angiopoietins, PI3K/AKT/mTOR, HIF-α-mediated and PDGF/PDGF-R-β pathways. We focus on the role of these pathways in the pathogenesis of IH, how they are altered and the consequences of these abnormalities. In addition, we review the latest preclinical and clinical data on the rationally designed targeted agents that are now being directed against some of these pathways. PMID:24479731

    2015-01-01

    Background: Cavernomas are benign lesions that most commonly occur intra-parenchymally, but occasionally they have been described as arising from the dura mater. Extra-axial cavernous angiomas (or hemangiomas) account for 0.4–2% of all intracranial vascular malformations, and they usually occur in the middle cranial fossa, associated with the cavernous sinus. Other possible localizations (e.g. tentorium, convexity, anterior cranial fossa, cerebellopontine angle, Meckel's cave, sella turcica and internal auditory meatus) are rare, and they account only for 0.2–0.5%. Case Description: We report a case of a 30-year-old female presenting with a 2 years history of headache unresponsive to drug therapy. The magnetic resonance imaging showed a dural-based lesion in the left frontal region; the lesion size was: 1.5 cm × 3.5 cm. The appearance suggested a convexity meningioma. A left frontal craniotomy was performed, and the histopathological diagnosis deposed for a cavernous hemangioma of the dura mater. The follow-up at 1-year was good without any neurologic deficit. Conclusions: Dural-based cavernous hemangiomas of the convexity are uncommon lesions. Up to now, only 13 cases have been described in the literature. The authors have discussed clinical aspects, radiological features, surgical treatment, and operative findings. PMID:26421218

    To evaluate changes in infantile hemangioma tissue before and after propranolol therapy, using gray-scale and color Doppler ultrasound imaging. Case series with chart review. Tertiary pediatric hospital. Medical records and image studies of head and neck infantile hemangioma patients treated with propranolol, identified in a quality improvement database, were reviewed. Patients with imaging before and at least 4 weeks following the initiation of treatment were included. Data collected included sex, age, location, and concurrent treatment. Student t tests were used to evaluate change in cutaneous lesion area, volume, and vessel density. Logistic regression was used to compare lesion area, volume, and vessel density. Of the 177 patients identified, 19 met inclusion criteria. Fourteen of 19 were female, and 5 of 19 were older than 1 year. Mean lesion area change with treatment was 13.0 cm(2) (range, -2.8 to 28.9 cm(2), P = .05). Measured volume change was a mean of 10.3 cm(3) (range, 1.5-19.2 cm(3), P = .01). Mean vessel density change was 4.4 vessels per cm(2) (range, 2.5-6.3 vessels per cm(2), P < .01). Treatment decreased clinically determined hemangioma area proportionately less than gray-scale and color Doppler ultrasound measured lesion volume. Gray-scale and color Doppler ultrasound measured treatment response did not differ with sex, lesion location, or age at propranolol initiation. Gray-scale and color Doppler ultrasound imaging of propranolol-treated infantile hemangiomas detected a significant reduction in lesion volume and vessel density. Patient age at propranolol treatment and concomitant corticosteroid use did not affect lesion volume change.

    2013-03-01

    We reviewed the epidemiology, clinical characteristics, disease severity, and economic burden of influenza B as reported in the peer-reviewed published literature. We used MEDLINE to perform a systematic literature review of peer-reviewed, English-language literature published between 1995 and 2010. Widely variable frequency data were reported. Clinical presentation of influenza B was similar to that of influenza A, although we observed conflicting reports. Influenza B-specific data on hospitalization rates, length of stay, and economic outcomes were limited but demonstrated that the burden of influenza B can be significant. The medical literature demonstrates that influenza B can pose a significant burden to the global population. The comprehensiveness and quality of reporting on influenza B, however, could be substantially improved. Few articles described complications. Additional data regarding the incidence, clinical burden, and economic impact of influenza B would augment our understanding of the disease and assist in vaccine development.

  2. The joy at birth: an interpretive hermeneutic literature review.

    Crowther, Susan; Smythe, Elizabeth; Spence, Deb

    2014-04-01

    this literature review examines the experience of joy at birth and what that joy means. The premise is that the whole of the birthing experience has not been fully explicated in the literature and that something of significance remains unexplored and unspoken. It is argued that a hermeneutic phenomenological approach to reviewing literature provides unique insights and leads to deeper understandings about birth and the experience of joy that attunes at that moment. the philosophical underpinnings informed by Heidegger and Gadamer are central to this review and therefore the process of reviewing literature hermeneutically is described. Heideggerian phenomenology is used as the method to ask the questions of the literature in order that concealed and hidden experiences of joy at birth are made visible where they are gleaned from the literature. A hermeneutic lens is used to uncover relationships within the phenomenon of joy at birth and meaning. although a vast birth literature was reviewed joy at birth was often ignored, hidden or covered over. Reviewing the literature on relationships, professional presence, place of birth, birth satisfaction studies and birth as peak and spiritual experience provides glimpses of the phenomenon 'joy at birth'. it is argued that joy at birth remains largely neglected as a phenomenon worthy of consideration. Plausible interpretations are presented that suggest that joy at birth points to something significant and meaningful. Spiritual and sacred meaning is alluded to in the papers reviewed yet the majority of papers that investigate birth leave this meaning unspoken. The review highlights a need for further thinking and questioning about birth that would direct on-going investigation. Copyright © 2014 Elsevier Ltd. All rights reserved.

  3. Integrative Literature Review: Ascertaining Discharge Readiness for Pediatrics After Anesthesia.

    Whitley, Deborah R

    2016-02-01

    Unplanned hospital readmissions after the administration of general anesthesia for ambulatory procedures may contribute to loss of reimbursement and assessment of financial penalties. Pediatric patients represent a unique anesthetic risk. The purpose of this integrative literature review was to ascertain specific criteria used to evaluate discharge readiness for pediatric patients after anesthesia. This study is an integrative review of literature. An integrative literature search was conducted and included literature sources dated January 2008 to November 2013. Key words included pediatric, anesthesia, discharge, criteria, standards, assessment, recovery, postoperative, postanesthesia, scale, score, outpatient, and ambulatory. Eleven literature sources that contributed significantly to the research question were identified. Levels of evidence included three systematic reviews, one randomized controlled trial, three cohort studies, two case series, and two expert opinions. This integrative literature review revealed evidence-based discharge criteria endorsing home readiness for postanesthesia pediatric patients should incorporate consideration for physiological baselines, professional judgment with regard to infant consciousness, and professional practice standards/guidelines. Additionally, identifying and ensuring discharge to a competent adult was considered imperative. Nurses should be aware that frequently used anesthesia scoring systems originated in the 1970s, and this review was unable to locate current literature examining the reliability and validity of their use in conjunction with modern anesthesia-related health care practices.

  4. Solid fuel grindability: a literature review

    SciTech Connect

    Hills, L.

    2007-07-01

    The most commonly used measurement of coal grindability is the Hardgrove Grindability Index (HGI) however, many solid fuels do not exhibit the grinding performance predicted by this index. Parameters which can influence grindability and possibly lead to inaccurate prediction of grindability as determined by HGI include: composition and texture, mineral components, brittleness, and rank (which establishes carbon, volatile matter, and moisture contents). Descriptions of these parameters are provided. Alternative measurements of grindability from literature are presented. The most promising may be a revision on the standard HGI, in which a mill capacity factor is derived from the number of mill rotations to crush coal to a specific fineness. 88 refs.

  5. Case report: living donor liver transplantation for giant hepatic hemangioma using a right lobe graft without the middle hepatic vein

    PubMed Central

    2014-01-01

    Hepatic hemangioma patients with Kasabach-Merritt syndrome have reportedly been cured by liver transplantation. However, liver transplantation as a potential cure for a stable patient without Kasabach-Merritt syndrome remains debatable. We report the case of a 27-year-old female patient with a giant hepatic hemangioma. The hemangioma measured 50 × 40 × 25 cm in size and weighed 15 kg, which is the largest and heaviest hemangioma reported in the literature. The patient showed jaundice, ascites, anemia, and appetite loss; but no disseminated intravascular coagulation was observed through laboratory findings. We successfully operated using a right lobe graft without the middle hepatic vein from a 55-year-old donor. At the long-term follow-up, the patient experienced two acute rejections, which were confirmed by biopsy. However, the patient still survives with good graft function after 50 months. PMID:24708716

    Scientific software plays an important role in critical decision making, for example making weather predictions based on climate models, and computation of evidence for research publications. Recently, scientists have had to retract publications due to errors caused by software faults. Systematic testing can identify such faults in code. This study aims to identify specific challenges, proposed solutions, and unsolved problems faced when testing scientific software. We conducted a systematic literature survey to identify and analyze relevant literature. We identified 62 studies that provided relevant information about testing scientific software. We found that challenges faced when testing scientific software fall into two main categories: (1) testing challenges that occur due to characteristics of scientific software such as oracle problems and (2) testing challenges that occur due to cultural differences between scientists and the software engineering community such as viewing the code and the model that it implements as inseparable entities. In addition, we identified methods to potentially overcome these challenges and their limitations. Finally we describe unsolved challenges and how software engineering researchers and practitioners can help to overcome them. Scientific software presents special challenges for testing. Specifically, cultural differences between scientist developers and software engineers, along with the characteristics of the scientific software make testing more difficult. Existing techniques such as code clone detection can help to improve the testing process. Software engineers should consider special challenges posed by scientific software such as oracle problems when developing testing techniques.

    2011-12-01

    Methamphetamine (METH) use and dependence is a serious public health concern with implications across multiple areas from societal impact to burden on psychiatric and medical resources. An estimated 8% of admissions to substance abuse treatment programs are related to stimulants with METH/amphetamine abuse. To date, effective pharmacotherapy options to enhance abstinence have not been identified. The objective of this article is to critically review the literature of METH treatment options. Preclinical research and human research with compounds not yet available commercially in the United States will not be included. A literature review was conducted for research on pharmacological treatments for METH use and addiction. Trial information on the use of sertraline, bupropion, mirtazapine, modafinil, dextroamphetamine, ondansetron, risperidone, aripiprazole, baclofen, and gabapentin was reviewed. Aripiprazole trials appeared in the reviewed literature more frequently than the other medications. Based on the findings of this review, no single medication demonstrated consistent efficacy and each trial contained a variety of methodological limitations.

    As the specialty of emergency medicine evolves in countries around the world, and as interest in international emergency medicine (IEM) grows within the United States, the IEM Literature Review Group recognizes an ongoing need for a high-quality, consolidated, and easily accessible evidence base of literature. The IEM Literature Review Group produces an annual publication that strives to provide readers with access to the highest quality and most relevant IEM research from the previous year. This publication represents our fifth annual review, covering the top 24 IEM research articles published in 2009. Articles were selected for the review according to explicit, predetermined criteria that emphasize both methodologic quality and impact of the research. It is our hope that this annual review acts as a forum for disseminating best practices, while also stimulating further research in the field of IEM. © 2010 by the Society for Academic Emergency Medicine.

  18. The Rare Association of Spina Bifida and Extrarenal Wilms Tumor: A Case Report and Review of the Literature.

    The diagnosis of nephroblastoma outside of the kidneys, in the absence of a renal primary tumor, is known as extrarenal Wilms tumor (ERWT). ERWT is an uncommon entity that typically involves the embryonic path of the developing kidneys and gonads. The occurrence of ERWT in a dysraphic spine is uncommon, with no reported cases of preoperative diagnosis, with all cases diagnosed at pathology. These tumors are malignant and ideally should be completely excised. Thus, preoperative diagnosis would be highly desirable. A newborn female was found to have a lumbar lipoma. Magnetic resonance imaging (MRI) was performed to rule out lipomyelomeningocele. The MRI showed a dorsal lipoma on the terminal spinal cord, as well as a 2 × 2 cm uniformly enhancing mass abutting the bifid posterior elements of L5. The lesion was completely excised, and the pathological diagnosis was ERWT. We report this case with a review of the literature to raise awareness of this association, illustrate the key imaging findings, and document the clinical outcome. The lack of pathognomonic radiologic features makes the preoperative diagnosis extremely difficult, but a diagnosis of ERWT should be considered in the context of a soft tissue mass without the typical imaging features of a hemangioma or teratoma.

    To carry out an extensive review of the literature on tooth staining with particular regard to some of the more recent literature on the mechanisms of tooth staining involving mouthrinses. Comprehensive review of the literature over four decades. A knowledge of the aetiology of tooth staining is of importance to dental surgeons in order to enable a correct diagnosis to be made when examining a discoloured dentition and allows the dental practitioner to explain to the patient the exact nature of the condition. In some instances, the mechanism of staining may have an effect on the outcome of treatment and influence the treatment options the dentist will be able to offer to patients.
