    Bilateral medial medullary infarction (MMI) is a rare type of stroke with poor outcomes. Inferior olivary nucleus hypertrophy results from a pathologic lesion in the Guillain-Mollaret triangle. The relationship between inferior olivary nucleus hypertrophy and the medullary lesion is obscure. To the best of our knowledge, only 1 autopsy case with unilateral medial medullary infarction that was associated with ipsilateral inferior olivary nucleus hypertrophy has been reported. We describe a rare case with acute infarction in the bilateral medial medulla oblongata accompanied by subacute bilateral inferior olivary nucleus hypertrophy and panmedullary edema. The hypertrophy appeared to have been caused by local ischemic damage to the termination of the central tegmental tract at the bilateral inferior olivary nucleus.

    The POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) is a rare paraneoplastic syndrome based on a clonal plasma cell disorder. Optic disc edema (ODE) is a frequent ocular sign in POEMS syndrome. The cause of the ODE has not yet been entirely clarified. This article reports the case of a 62-year-old male suffering from POEMS syndrome with a bilateral ODE.

    A 5-month-old infant presented with bilateral abdominoscrotal hydroceles since birth and left leg edema and cyanosis. An ultrasound of the abdomen showed a cystic mass. Computed tomography showed a fluid filled mass extending intra-abdominally through the inguinal canal from the scrotum. A bilateral hydrocelectomy was performed, and the proximal sac was completely excised through the inguinal incision. The edema of the left leg resolved 2 days after surgery. The postoperative course was uneventful, without complication.

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

    Full Text Available La distensión abdominal es un síntoma común, siendo en general la presentación inicial de enfermedades sistémicas o desórdenes gastrointestinales. Otras causas son infrecuentes. Los quistes del cordón espermático son poco frecuentes, pero aún más su ubicación intraabdominal, su tamaño habitual es insuficiente para producir distensión. El paciente presentado en este caso es un varón con criptorquidia bilateral admitido por distensión abdominal, interpretada inicialmente como síndrome ascítico edematoso. La ecografía interpretó la distensión como ascitis tabicada, y la tomografía computada como debida a un gran quiste. En la exploración quirúrgica se diagnosticó un quiste gigante del cordón espermático de ubicación abdominal.Abdominal distention is a frequent symptom, being often the initial presentation of systemic diseases or gastrointestinal disorders. Other causes are uncommon. Spermatic cord cysts are infrequent, abdominal location is even rarer, and the size of the cysts is usually not enough to produce abdominal distention. In our case a man with bilateral cryptorchidism was admitted with abdominal distention and edema of the lower extremities initially interpreted as ascitic-edematous syndrome. Ultrasonography interpreted abdominal distention as septate ascites, computed tomography as a giant cyst. Exploratory surgery showed a giant spermatic cord cyst in the left spermatic cord.

    Femoral neck fractures resulting from pregnancy-associated osteoporosis is a rare condition. Herein, we report an undoubted case of pregnancy-associated osteoporosis in a 38-year-old primiparous patient with pre-existing anorexia nervosa who suffered bilateral femoral neck fractures in the third trimester and early post-partum period. Magnetic resonance imaging revealed femoral neck fractures as well as diffuse marrow edema involving both femoral heads, which are considered under ordinary circumstances as characteristic imaging findings of transient osteoporosis of the hip. Based on our experience, we propose that pregnancy-associated osteoporosis might be present in femoral neck fractures attributed to transient osteoporosis of the hip in pregnancy. Conversely, bone status should be carefully and accurately estimated in cases of potential transient osteoporosis of the hip in pregnancy to reduce future fracture risk. © 2017 The Authors Journal of Obstetrics and Gynaecology Research published by John Wiley & Sons Australia, Ltd on behalf of Japan Society of Obstetrics and Gynecology.

    To describe a case of a patient with multiple myeloma without extraocular end-organ damage but with cystoid macular edema and macular detachments who was treated with bortezomib and dexamethasone. There was a complete resolution of retinal and subretinal fluid and significant improvement of vision. The patient's ocular disease was monitored with visual acuity, dilated fundus examinations, and optical coherence tomography before, during, and after treatment. The patient in this case report was a 43-year-old African American man with a medical history of untreated, "smoldering" multiple myeloma, hypertension, hyperlipidemia who presented to our clinic with progressive painless loss of vision in both eyes over 6 weeks. Before treatment with bortezomib and dexamethasone, the patient had complaints of confusion, muscle stiffness, joint pain, and 20-lb unintentional weight loss; however, he did not have hypercalcemia, renal insufficiency, anemia, or bone lesions typical of active multiple myeloma. The bilateral cystoid macular edema and subfoveal neurosensory retinal detachments, noted on presentation and confirmed by optical coherence tomography, completely resolved over the course of treatment with bortezomib and dexamethasone. This case of bilateral cystoid macular edema and subfoveal neurosensory retinal detachments is remarkable for both its presentation and response to therapy. The macular edema and macular detachments along with nonspecific complaints of confusion, muscle stiffness, joint pain, and weight loss were the presenting signs and symptoms; signs typically used as guides to initiate treatment for multiple myeloma were not present. Macular edema in the context of paraproteinemia is usually associated with Waldenstrom's macroglobulinemia and has classically been reported as "silent" with respect to fluorescein angiography. Our patient has multiple myeloma and demonstrated leakage on fluorescein angiography. The case is also notable in that there was

Ocular side effects such as intraocular pressure (IOP, cataract, and tolerability of bilateral injections was reviewed.Results: Twenty-two eyes of eleven patients treated with a total of 32 DEX implants were included. Ten of eleven patients received bilateral implants due to active noninfectious uveitis while the other demonstrated macular edema in both eyes following separate central retinal vein occlusions. Among the patients with bilateral uveitis, the mean interval between DEX implant in the initial eye and the subsequent DEX in the fellow eye was 15.6 days (range 2–71 days. Seven of the ten patients received the second implant in the fellow eye within 8 days of the initial implantation. None of the patients had bilateral implantations on the same day. Seven eyes required reimplantation for recurrence of inflammation (mean interval between first and repeat implantation was 6.00±2.39 months. Following single or, in the case of the aforementioned seven eyes, repeat DEX implantation, all 20 uveitic eyes demonstrated clinical and/or angiographic evidence of decreased inflammation in the form of reduction in vitreous cells on slit lamp ophthalmoscopy, macular edema on ophthalmoscopy, or optical coherence tomography and/or disc and vascular leakage on fluorescein angiography.

Algunos datos son descriptivos y reflejan la situación actual: en los países avanzados solo 30 % de los diabéticos tipo I están adecuadamente controlados y 7 % de los tipo 2 con características de alto riesgo no han sido revisados nunca por ningún oftalmólogo. La prevalencia de la retinopatía diabética está determinada por el tipo de diabetes mellitus y por la edad del paciente, disminuye según aumenta la edad. La retinopatía diabética más frecuente es la no proliferativa en un 80 %, contra un 20 %, la proliferativa. La diabetes mellitus en Cuba tiene una prevalencia aproximadamente de 1/10 000. Estudios recientes revelan una prevalencia de la retinopatía diabética de alrededor de 20-25 % entre los pacientes diabéticos. La detección temprana de la retinopatía, el edema macular, y el tratamiento precoz son cruciales en el esfuerzo por reducir la incapacidad visual presentada en los pacientes con diabetes. En este trabajo se evalúa la efectividad de la triamcinolona intravítrea como tratamiento general antiangiogénico y antiinflamatorio del edema macular en un grupo de pacientes diabéticos que fueron atendidos en el Instituto Cubano Oftalmológico "Ramón Pando Ferrer, desde enero hasta julio de 2006.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A neuralgia do nervo trigêmeo é uma condição intensamente dolorosa, caracterizada por surtos de dor lancinante e súbita, tipo choque, com duração de poucos segundos a dois minutos e geralmente unilateral. Sua incidência anual é de cerca de 4,3 em 100.000 na população geral, tendo manifestação bilateral em apenas 3% desses casos. O objetivo deste artigo foi descrever um caso raro de neuralgia do trigêmeo primário bilateral. RELATO DO CASO: Paciente de 61 anos, maranhense, casada, do lar, com antecedente de hipertensão arterial e há seis anos com queixa de dor intensa em V2-V3 à esquerda, com duração de 5 a 10 segundos, em região lateral do nariz e mandibular, com piora ao falar, mastigar e com diminuição da temperatura. Já havia utilizado clorpromazina (3 mg a cada oito horas e carbamazepina (200 mg a cada oito horas durante seis meses sem alívio da dor. Ao exame físico apresentava alodinia térmica e mecânica em regiões de V2-V3. Estava em uso de gabapentina (1.200 mg ao dia com alívio parcial da dor. Foi então aumentada a gabapentina para 1500 mg ao dia e introduzida amitriptilina 12,5 mg à noite. Evoluiu com dor leve e esporádica com diminuição da intensidade da dor ao longo de 10 meses de tratamento, sendo reduzida progressivamente a gabapentina para 600 mg ao dia e mantida a amitriptilina 12,5 mg ao dia. Após um ano, começou a apresentar dor de característica semelhante em região mandibular à direita, tendo melhorado com aumento de gabapentina para 900 mg ao dia. Não apresentava exames alterados de tomografia ou ressonância magnética de encéfalo. CONCLUSÕES: A carbamazepina é o fármaco de primeira escolha para tratamento de neuralgia trigeminal, porém a gabapentina tem sido cada vez mais utilizada como primeira medida farmacológica ou em casos refratários à terapia convencional.JUSTIFICATIVA Y OBJETIVOS: La neuralgia del nervio trigémino es una condici

    Zoledronic acid-induced uveitis (ZAIU) is rare but severe, and has been recently considered part of an acute phase reaction. Only 15 cases have been reported since 2005. Here we describe a case with macular edema, which is the first reported case observed after long-term alendronate tolerance. A 63-year-old Asian woman received her first intravenous zoledronic acid treatment for the management of postmenopausal osteoporosis as a more convenient substitute for oral alendronate. Twenty-four hours later, bilateral eye irritations, periorbital swelling, blurred vision, and diplopia presented. The complete blood count and transaminase levels were normal, but the erythrocytic sedimentation, C-reactive protein, and serum C4 levels were elevated. On detailed ophthalmological examination, a diagnosis of bilateral acute uveitis and macular edema in the right eye was made. The ocular symptoms were not improved until administration of topical and oral steroids. Complete resolution was achieved. There was no rechallenge of bisphosphonates, and no recurrence at 6 months follow-up. Based on an extensive review, abnormal fundus is rarely reported, especially in cases of macular edema. Rechallenge with zoledronic acid in five cases induced no additional uveitis, and changing the medication to pamidronate in another patient was also tolerated. Interestingly, our patient suffered from uveitis soon after intravenous zoledronate exposure after a two-year tolerance to oral alendronate. This is the first report of zoledronic acid induced uveitis with macular edema after long-term alendronate tolerance. Prior oral alendronate may not entirely prevent ZAIU. Steroids are usually necessary in the treatment of ZAIU. Bisphosphonate rechallenge is not fully contraindicated, and prior steroid administration may be a more reasonable treatment choice according to the available evidence.

El edema pulmonar de altura (EPA es una entidad que pone en peligro la vida y que ocurre en sujetos predispuestos pero sanos. Esto permite estudiar los mecanismos subyacentes del edema pulmonar en humanos, sin la presencia de factores que presten a la confusión como enfermedades concomitantes. El EPA resulta de la conjunción de dos defectos mayores: acumulación de líquido en el espacio alveolar debido a una hipertensión pulmonar hipóxica exagerada, y alteración en la eliminación del mismo por un defecto en el transporte transepitelial alveolar de sodio. En esta revisión, describimos brevemente las características clínicas y revisaremos este novedoso concepto. Proveemos evidencia experimental de como la síntesis alterada de óxido nítrico y/o la disminución de su biodisponibilidad representan el defecto central que predispone a la vasoconstricción pulmonar hipóxica exagerada y a la acumulación de líquido en el espacio alveolar. Mostramos que la hipertensión pulmonar hipóxica exagerada, per se, no es suficiente para producir un EPA, y que una alteración en la eliminación del fluido del espacio alveolar representa un segundo mecanismo fisiopatológico importante. Finalmente, describimos cómo los nuevos aportes obtenidos de los estudios del EPA pueden ser trasladados al manejo de otros estados patológicos ligados a la hipoxemia.High altitude constitutes an exciting natural laboratory for medical research.

    To compare the efficacy of intravitreal bevacizumab (IVB) injection alone or with intravitreal triamcinolone acetonide (IVB/IVT) versus macular photocoagulation (MPC) in bilateral diabetic macular edema (DME). In this study we revisited data from a subset of subjects previously enrolled in a randomized clinical trial. The original study included 150 eyes randomized to three treatment arms: 1.25 mg IVB alone, combined injection of 1.25 mg IVB and 2 mg IVT, and focal or modified grid MPC. To eliminate the possible effects of systemic confounders, we selected fellow eyes of bilaterally treated subjects who had undergone different treatments; eventually 30 eyes of 15 patients were re-evaluated at baseline, 6, 12, 18, and 24 months. Using mixed model analysis, we compared the treatment protocols regarding visual acuity (VA) and central macular thickness (CMT). Improvement in VA in the IVB group was significantly greater compared to MPC at months 6 and 12 (P = 0.037 and P = 0.035, respectively) but this difference did not persist thereafter up to 24 months. Other levels of VA were comparable at different follow-up intervals (all P > 0.05). The only significant difference in CMT was observed in favor of the IVB group as compared to IVB/IVT group at 24 months (P = 0.048). Overall VA was superior in IVB group as compared to MPC up to 12 months. Although the IVB group showed superiority regarding CMT reduction over 24 months as compared to IVB/IVT group, it was comparable to the MPC group through the same period of follow up.

  5. Large right atrial myxoma containing gastric heterotopia presenting with dyspnea and bilateral leg edema due to pulmonary emboli and cardiovascular obstruction: the first known report of gastric heterotopia in the cardiovascular system.

    Cappell, Mitchell S; Lapin, Seth; Rose, Malcolm

    2008-02-01

    A 52-year-old male presented with progressive dyspnea, bilateral leg edema, and elevated central venous pressure due to a large right atrial myxoma that caused vascular obstruction and pulmonary emboli. The myxoma contained gastric heterotopia. Other unusual features of this atrial myxoma included its large size, right atrial location, and attachment to the right atrial wall. Although gastric heterotopia has been reported throughout the gastrointestinal tract, and occasionally in other organs, this is the first report of gastric heterotopia in the cardiovascular system. This report confirms and extends previous reports of glandular elements or enteric glands within atrial, or cardiac, myxomas. The clinical presentation of the currently reported patient is explained as follows: the elevated central venous pressure resulted from cardiovascular obstruction and the dyspnea from multiple pulmonary emboli due to the large atrial myxoma. In this case, the clinical presentation was not attributable to the gastric heterotopia. The association of gastric heterotopia with atrial myxoma may, however, be clinically important because of the propensity of gastric heterotopia in the gastrointestinal tract to produce complications. The reported association may provide clues to the histogenesis of these two entities.

  6. Nephritic edema.

    Kurtzman, N A

    2001-05-01

    Nephritic edema results from the primary retention of salt. Acute glomerulonephritis is the prototypical form of the disorder. The stimulus for the salt retention arises within the kidney by an unknown mechanism. As effective arterial blood volume (EABV) was normal at the start of the disease process, it becomes expanded as salt and water are added to it. The pathophysiological sequelae of this process are compared with those which follow the salt retention of congestive heart failure (CHF). The latter is a syndrome in which salt retention is secondary, driven by the contraction of EABV which is at the heart of CHF. Finally, mechanisms responsible for the salt retention of nephrosis are considered. It is possible, and even likely, that most patients with nephrotic edema have primary salt retention, rather than secondary edema. If this view is correct, salt is retained not because of urinary protein loss and its consequent hypoalbuminemia, but rather because of the glomerulopathy which caused the syndrome in the first place.

Se evaluaron, como parte de una investigación prospectiva, la edad, el sexo, los antecedentes patológicos personales, los exámenes complementarios preoperatorios, el tiempo de retirada de los tubos pleurales, las complicaciones, la mortalidad, la evolución posoperatoria a los 6 y 12 meses y se comparó la utilidad de esta técnica con la convencional. Los datos obtenidos se procesaron mediante un programa computadorizado, con el objetivo de expresarlos en forma de tablas y figuras. La quinta década de la vida y el sexo masculino fueron los más afectados. Los exámenes complementarios preoperatorios más utilizados fueron la radiografía y fluoroscopia de tórax, la gasometría y las pruebas funcionales ventilatorias. La disnea fue el síntoma más frecuente, el tiempo promedio de retirada de los tubos pleurales fue de ocho días, la fuga aérea fue la complicación encontrada con mayor frecuencia, no hubo mortalidad operatoria, la evolución posoperatoria fue excelente y la comparación entre ambas técnicas quirúrgicas demostró la superioridad científica, económica y social de la resección simultánea del enfisema bulloso bilateral por esternotomía media. De los resultados anteriores se concluye que el tratamiento quirúrgico simultáneo del enfisema bulloso bilateral por

    Superolateral Hoffa's fat pad (SHFP) edema is a previously described magnetic resonance (MR) finding located between the patellar tendon and the lateral femoral condyle. The purpose of our study was to determine the prevalence and clinical significance of SHFP edema in female collegiate volleyball players. Sixteen female collegiate volleyball players were consented for bilateral knee evaluations which consisted of history, physical examination and MR imaging. Each MR study was reviewed for the presence of SHFP edema, and 6 patellar maltracking measurements were done. These were tibial tuberosity-trochlear groove distance, patellar translation, lateral patellofemoral angle, trochlear depth, trochlear sulcus angle, and lateral trochlear inclination angle. A total of 16 athletes, 32 knees (16 girls; age range, 18-22 years; mean, 19.9) were enrolled in the study. Sixteen knees (50%) in 8 athletes had SHFP edema, with 100% bilaterality; 16 knees in 8 athletes had no evidence of SHFP edema (50%). Functional outcomes and physical examination findings were within normal limits for all athletes with no difference noted between SHFP edema-positive and -negative individuals. There was a statistically significant difference in the tibial tuberosity-trochlear groove distance, patellar translation, and patellofemoral angle (P value of volleyball athletes have a very high prevalence of SHFP edema, which is always bilateral. Although the exact etiology of SHFP edema remains inconclusive, it could potentially be a sensitive indicator of subtle patellar maltracking which cannot be distinguished by history and physical examination findings. Given the very high prevalence of SHFP edema and this being an asymptomatic finding, there is likely little clinical significance of this in majority of high-performance athletes.

    Neurogenic pulmonary edema is an underrecognized and underdiagnosed form of pulmonary compromise that complicates acute neurologic illness and is not explained by cardiovascular or pulmonary pathology. This review aims to provide a concise overview on pathophysiology, epidemiology, clinical characteristics, impact on outcome and treatment of neurogenic pulmonary edema, and considerations for organ donation. Database searches and a review of the relevant medical literature. Selected studies included English-language articles concerning neurogenic pulmonary edema using the search terms "neurogenic" with "pulmonary oedema" or "pulmonary edema," "experimental neurogenic pulmonary edema," "donor brain death," and "donor lung injury." Selected studies were reviewed by both authors, and data extracted based on author consensus regarding relevance for this review. Existing evidence is organized to address: 1) pathophysiology, 2) epidemiology and association with different neurologic diseases, 3) clinical presentation, 4) impact on outcome, 5) treatment, and 6) implications for organ donation after brain death. Neurogenic pulmonary edema occurs as a complication of acute neurologic illness and may mimic acute lung injury of other etiology. Its presence is important to recognize in patients due to its impact on clinical course, prognosis, and treatment strategies.

    Full Text Available Cystoid macular edema (CME is a condition that involves the macula, causing painless vision loss. In this paper, we report a case of niacin-induced bilateral cystoid macular edema (CME in a middle-age woman taking low dose of niacin (18 mg of nicotinic acid. Optical coherence tomography (OCT showed retinal thickening and cystoid spaces in both eyes, whereas fluorescein angiography (FA; HRA 2, Heidelberg Engineering revealed the absence of fluorescein leakage also in later phases. Four weeks after discontinuation of therapy there were a complete disappearance of macular edema at funduscopic examination and an improvement of visual acuity in both eyes. Furthermore OCT showed a normal retinal profile in both eyes. In our opinion considering the wide availability of niacin, medical monitoring and periodical examination should be considered during niacin administration. To our knowledge, this is the first report in the literature that described the very low-dose niacin-induced bilateral niacin maculopathy.

    Full Text Available Xanthogranulomas (XGRs of the choroid plexus are rare, asymptomatic, and benign lesions usually found incidentally. Here, we present a case of a 47-year-old male with bilateral XGR of the choroid plexus with periventricular edema and discuss our case in relation to a review of existing literature pertaining to the radiology of XGRs. To the best of our knowledge, this is the first reported case of bilateral trigonal XGR causing brain edema without ventricular dilatation. Despite the fact that they can cause hydrocephalus, XGRs are silent and benign lesions. Although the etiopathology of XGRs remains poorly understood, enhanced imaging analyses may provide additional information regarding edema and focal white matter signal changes.

    Despite the fact that it has been used since the 1960s in diseases associated with brain edema and has been investigated in >150 publications on head injury, very little has been published on the outcome of osmotherapy. We can only speculate whether osmotherapy improves outcome, has no effect......, osmotherapy can be negative for outcome, which may explain why we lack scientific support for its use. These drawbacks, and the fact that the most recent Cochrane meta-analyses of osmotherapy in brain edema and stroke could not find any beneficial effects on outcome, make routine use of osmotherapy in brain...... edema doubtful. Nevertheless, the use of osmotherapy as a temporary measure may be justified to acutely prevent brain stem compression until other measures, such as evacuation of space-occupying lesions or decompressive craniotomy, can be performed.

  13. [Acute neurogenic pulmonary edema].

    Science.gov (United States)

    Roquefeuil, B

    1975-01-01

    Neurogenic edema, in the strict sense of the term, has at the present time practically not benefitted from precise hemodynamic investigations in human clinical practice, and owing to this fact, authors still classify them under the heading "mixed edema or of unknown pathogenesis". In contrast with this lack of information in man, animal experimental works are surprising by their coherence and the experimental facility of producing neurogenic edema (cranial hypertension by a small inflatable balloon and cisternal infection of fibrin). If one excludes the now ancient vagal theories (CAMERON 1949; CAMPBELL, 1949) which were never confirmed, all of the most recent experimental works (SARNOFF, 1952; DUCKER, 1968; LUISADA, 1967; MORITZ, 1974) confirm the adrenergic disorder of central origin during neurogenic A.P.E. which from the hemodynamic standpoint is like an authentic hemodynamic A.P.E. with raised left atrial pressure, pulmonary venous pressure and pulmonary capillary pressure.

    Full Text Available Masumi G Asahi, Calvin Chou, Ron P Gallemore Retina Macula Institute, Torrance, CA, USA Purpose: We aimed to describe the first case of macular edema following intracorporeal injection of alprostadil, a prostaglandin E1. Methods: This was a retrospective case report followed with optical coherence tomography, fundus photos, and fluorescein angiography images. Results: A patient developed bilateral cystoid macular edema following intracorporeal injection of alprostadil, a prostaglandin E1 for treatment of erectile dysfunction. The edema resolved following treatment with nonsteroidal anti-inflammatory drugs (NSAIDs and corticosteroids, with subsequent recovery in visual acuity. Discussion: Systemic prostaglandin administration can cause macular edema and vision loss, indicating that elevated systemic prostaglandin levels may affect visual function. This has potential implications for other systemic disorders and treatments that could affect macular function. Keywords: alprostadil, inflammation

    Edema is defined as the condition in which intraluminal lymph fluid components leak into the tissues and the interstitium fluid is abnormally increased. At the site of edema, toxication, allergy or inflammation occasionally occurs. This paper will focus on local skin and mucosal edema. Toxic edema is locally caused by intake of industrial goods or medical products (pharmaceuticals). Like urticaria, allergic edema is attributed to the increased vascular permeability caused by a chemical mediator. Inflammatory edema is the state in which increased inflammatory reaction in local skin causes increases in osmotic pressure of the tissues and metabolism and then inflammatory effusion accumulate there. It includes burn and cellulites.

  16. Exercise-Induced Pulmonary Edema in a Triathlon

    Full Text Available Introduction. Family physicians have more opportunities to attend athletic competitions as medical staff at first-aid centers because of the increasing popularity of endurance sports. Case. A 38-year-old man who participated in a triathlon race experienced difficulty in breathing after swimming and was moved to a first-aid center. His initial oxygen saturation was 82% and a thoracic computed tomography scan showed bilateral ground glass opacity in the peripheral lungs. His diagnosis was noncardiogenic pulmonary edema associated with exercise or swimming: exercise-induced pulmonary edema (EIPE or swimming-induced pulmonary edema (SIPE. Treatment with furosemide and corticosteroid relieved his symptoms of pulmonary edema. Discussion. Noncardiogenic pulmonary edema associated with endurance sports is not common, but knowledge about EIPE/SIPE or neurogenic pulmonary edema associated with hyponatremia, which is called Ayus-Arieff syndrome, is crucial. Knowledge and caution for possible risk factors, such as exposure to cold water or overhydration, are essential for both medical staff and endurance athletes. Conclusion. To determine the presence of pulmonary edema associated with strenuous exercise, oxygen saturation should be used as a screening tool at a first-aid center. To avoid risks for EIPE/SIPE, knowledge about these diseases is essential for medical staff and for athletes who perform extreme exercise.

  17. Pulmonary edema: radiographic differential diagnosis

    1997-01-01

    To evaluate the feasibility of using chest radiography to differentiate between three different etiologies of pulmonary edema. Plain chest radiographs of 77 patients, who were clinically confirmed as having pulmonary edema, were retrospectively reviewed. The patients were classified into three groups : group 1 (cardiogenic edema : n = 35), group 2 (renal pulmonary edema : n = 16) and group 3 (permeability edema : n = 26). We analyzed the radiologic findings of air bronchogram, heart size, peribronchial cuffing, septal line, pleural effusion, vascular pedicle width, pulmonary blood flow distribution and distribution of pulmonary edema. In a search for radiologic findings which would help in the differentiation of these three etiologies, each finding was assessed. Cardiogenic and renal pulmonary edema showed overlapping radiologic findings, except for pulmonary blood flow distribution. In cardiogenic pulmonary edema (n=35), cardiomegaly (n=29), peribronchial cuffing (n=29), inverted pulmonary blood flow distribution (n=21) and basal distribution of edema (n=20) were common. In renal pulmonary edema (n=16), cardiomegaly (n=15), balanced blood flow distribution (n=12), and central (n=9) or basal distribution of edema (n=7) were common. Permeability edema (n=26) showed different findings. Air bronchogram (n=25), normal blood flow distribution (n=14) and peripheral distribution of edema (n=21) were frequent findings, while cardiomegaly (n=7), peribronchial cuffing (n=7) and septal line (n=5) were observed in only a few cases. On plain chest radiograph, permeability edema can be differentiated from cardiogenic or renal pulmonary edema. The radiographic findings which most reliably differentiated these two etiologies were air bronchogram, distribution of pulmonary edema, peribronchial cuffing and heart size. Only blood flow distribution was useful for radiographic differentiation of cardiogenic and renal edema

    Full Text Available Acute dacryoadenitis is an uncommon condition that involves inflammation of the lacrimal gland. In rare instances, dacryoadenitis may be bilateral. A delay in proper treatment of an otherwise simple case of dacryoadenitis may lead to significant soft tissue morbidity such as cellulitis, lacrimal gland abscess, or orbital abscess. We report the case of a 24-year-old male who presented to the emergency department with acute bilateral dacryoadenitis. The patient′s symptoms did not respond to oral antibiotics and he subsequently required admission for intravenous antibiotics. During his hospitalization the patient had diagnostic testing to try to determine the etiology for his symptoms. The unique aspects of managing a case of bilateral dacryoadenitis as well as treatment recommendations are discussed in this case report.

    A 57-year-old woman experienced bilateral acute ischemic optic neuropathy after spine surgery. Routine MR imaging sequence, T2-weighted image, showed subtle high signal intensity on bilateral optic nerves. A contrast-enhanced T1 weighted image showed enhancement along the bilateral optic nerve sheath. Moreover, diffusion-weighted image (DWI) and an apparent diffusion coefficient map showed markedly restricted diffusion on bilateral optic nerves. Although MR findings of T2-weighted and contrast enhanced T1-weighted images may be nonspecific, the DWI finding of cytotoxic edema of bilateral optic nerves will be helpful for the diagnosis of acute ischemic optic neuropathy after spine surgery.

    Reperfusion following lower-torso ischemia in humans leads to respiratory failure manifest by pulmonary hypertension, hypoxemia, and noncardiogenic pulmonary edema. The mechanism of injury has been studied in the sheep lung lymph preparation, where it has been demonstrated that the reperfusion resulting in pulmonary edema is due to an increase in microvascular permeability of the lung to protein. This respiratory failure caused by reperfusion appears to be an inflammatory reaction associated with intravascular release of the chemoattractants leukotriene B 4 and thromboxane. Histological studies of the lung in experimental animals revealed significant accumulation of neutrophils but not platelets in alveolar capillaries. The authors conclude that thromboxane generated and released from the ischemic tissue is responsible for the transient pulmonary hypertension. Second, it is likely that the chemoattractants are responsible for leukosequestration, and third, neutrophils, oxygen-derived free radicals, and thromboxane moderate the altered lung permeability

    bom, com melhora na maioria dos casos nas primeiras 24 horas.JUSTIFICATIVA Y OBJETIVOS: Edema pulmonar por presión negativa pós-obstrucción de vía aérea actualmente es una entidad bien descrita, no obstante, probablemente poco diagnosticada y los casos poco publicados. El objetivo de este relato es presentar un caso de edema pulmonar por presión negativa pós-obstrucción de vía aérea superior, cuya principal característica fue la asimetría de edema pulmonar, siendo mucho más acentuado en el pulmón derecho. RELATO DEL CASO: Niño de 4 años, 17 kg, ASA I, fue sometido a adenoamigdalectomia y cauterización de cornetes, bajo anestesia general con sevoflurano/óxido nitroso/O2. La cirugía duró 1 hora y 30 minutos sin cualquier interocurrencia. Con la superficialización de la anestesia y el paciente, ventilando espontáneamente, reaccionó al tubo, que fue retirado. Después de esto, los esfuerzos ventilatorios resultaron en retracción de la pared torácica, sin aparente movimiento de aire siendo imposible ventilarlo con máscara facial, ocurriendo hipoxemia grave (SpO2 de 50% necesitando ser reintubado. En este momento fue verificado que el pulmón se encontraba más duro y había estertores bilateralmente, caracterizando edema pulmonar. Una radiografía de tórax mostró infiltración pulmonar difuso bilateralmente, no obstante, con atelectasia del lobo superior derecho, mostrando acentuada asimetría de edema pulmonar. El paciente tuvo que ser ventilado mecánicamente con PEEP durante 20 horas, cuando fue extubado. Hubo mejoría progresiva del edema pulmonar, recibiendo alta en 48 horas. CONCLUSIONES: El edema pulmonar por presión negativa es una entidad rara con alto grado de morbidad, poco diagnosticada y exige del anestesiologista conocimiento actualizado y tratamiento adecuado. Normalmente es bilateral, raramente unilateral y excepcionalmente con expresiva asimetría como en nuestro relato. La mayoría de los casos es tratada con soporte

    The treatment of diabetic macular edema has known a fast development in the last 5 years where the transition from laser monotherapy to intravitreal pharmacotherapy is becoming standard practice. Intravitreal injections therapy is in a continuous development with promising positive results. The use of intratvitreal devices in the treatment of macular edema of vascular cause has become a viable alternative also in treating diabetic macular edema. Several clinical studies have revealed the superiority of intravitreal treatment versus laser monotherapy. This article is evaluating and reviewing present and future treatments used to combat diabetic macular edema. [corrected].

    2016-03-01

    Advancements in molecular biology have led to a greater understanding of the individual proteins responsible for generating cerebral edema. In large part, the study of cerebral edema is the study of maladaptive ion transport. Following acute CNS injury, cells of the neurovascular unit, particularly brain endothelial cells and astrocytes, undergo a program of pre- and post-transcriptional changes in the activity of ion channels and transporters. These changes can result in maladaptive ion transport and the generation of abnormal osmotic forces that, ultimately, manifest as cerebral edema. This review discusses past models and current knowledge regarding the molecular and cellular pathophysiology of cerebral edema. © The Author(s) 2015.

    Bone marrow edema syndrome (BMES) refers to transient clinical conditions with unknown pathogenic mechanism, such as transient osteoporosis of the hip (TOH), regional migratory osteoporosis (RMO), and reflex sympathetic dystrophy (RSD). BMES is primarily characterized by bone marrow edema (BME) pattern. The disease mainly affects the hip, the knee, and the ankle of middle-aged males. Many hypotheses have been proposed to explain the pathogenesis of the disease. Unfortunately, the etiology of BMES remains obscure. The hallmark that separates BMES from other conditions presented with BME pattern is its self-limited nature. Laboratory tests usually do not contribute to the diagnosis. Histological examination of the lesion is unnecessary. Plain radiographs may reveal regional osseous demineralization. Magnetic resonance imaging is mainly used for the early diagnosis and monitoring the progression of the disease. Early differentiation from other aggressive conditions with long-term sequelae is essential in order to avoid unnecessary treatment. Clinical entities, such as TOH, RMO, and RSD are spontaneously resolving, and surgical treatment is not needed. On the other hand, early differential diagnosis and surgical treatment in case of osteonecrosis is of crucial importance. (orig.)

    Full Text Available Purpose: To report a case of diabetic macular edema with prominent chorioretinal folds. Case Report: This study involved a 55-year-old male with untreated bilateral diabetic retinopathy who had undergone cataract surgery at another clinic. Following that surgery, diabetic macular edema rapidly exacerbated, accentuating marked cystoid macular edema and radial chorioretinal folds in the macula. Investigation of his medical history revealed that in addition to diabetes, he had uncontrolled hypertension and severe diabetic nephropathy. Vitreous surgery was performed on both eyes due to a resistance to a subtenon injection of triamcinolone acetonide or intravitreal injection of an antivascular endothelial growth factor agent. After surgery, the macular edema and chorioretinal folds showed a tendency towards improvement. Thereafter, kidney transplant surgery was performed for renal failure, and a mild tendency of chorioretinal folds was observed. Conclusion: In the case presented in this study, we observed remarkable cystoid macular edema in the fovea centralis and theorize that distortion with the surrounding tissue might have occurred, thus leading to the formation of chorioretinal folds around the macula.

    We report a case of laryngeal edema associated with the Vogt-Koyanagi-Harada (VKH) syndrome. A 32-year-old African-American female presented with a 12-day prodrome, including headache, tinnitus and shortness of breath, which preceded sudden photophobia and bilateral visual loss. Examination and clinical testing were most consistent with VKH, and the patient improved with intravenous methylprednisolone therapy. The patient had persistent dyspnea, which was out of proportion to chest CT findings and which was exacerbated during a recurrence of VKH. Flexible fiberoptic laryngoscopy with stroboscopy revealed diffuse laryngeal edema. Symptoms were alleviated with breathing exercises. Several autoimmune diseases may cause diffuse laryngeal edema. In this case, VKH was associated with the patient's glottic edema and dyspnea. We recommend that laryngeal edema be considered in the differential diagnosis for patients with dyspnea and VKH.

    Lower extremity edema is extremely common among patients seen across multiple specialties. The differential diagnosis is broad and ranges from simple dependent edema to more complex conditions such as chronic venous disease and lymphedema. Several key features from the history and physical exam can assist with the diagnosis. Imaging is rarely necessary at the initial visit unless venous thromboembolism is suspected. Treatment is specific to the etiology of the edema, but compression stockings, elevation, exercise, and weight loss remain the cornerstone in most cases.

    Full Text Available A 39-year-old male was admitted to our clinic with symptoms of headache, dizziness, nausea, otalgia, otorrhea, tinnitus, and hearing loss in both ears for 3 weeks. Physical examination revealed edema in the tympanic membrane and external ear canal, and pain by palpation in the mastoid area bilaterally. There was no nystagmus, and the rest of the physical examination was otherwise normal. Temporal bone high resolution computed tomography (CT showed a lesion causing erosion in the mastoid cortex, tegmen tympani, ossicles, and in the bone covering the sigmoid sinus bilaterally. There was also erosion in the superior semicircular canal and petrous bone on the left side. Cortical mastoidectomy was performed under general anesthesia. Histopathologic examination of the tissue revealed Langerhans cell histiocytosis (LCH. In this paper a case with LCH, presenting with bilateral mastoid involvement which has been rarely reported in the literature, is discussed with the existing literature.

    Fiddler's neck is a dermatosis of violinists and violists. It characteristically presents as focal lichenification and pigmentation on the left side of the neck. Edema may also occur in the same area and lead to cosmetic concern or fear of malignancy. The edema apparently results from pressure on the patient's neck by the base of the violin or viola and is worsened by holding the instrument in a drooping position.

    2016-10-01

    Negative-pressure pulmonary edema (NPPE) or postobstructive pulmonary edema is a well-described cause of acute respiratory failure that occurs after intense inspiratory effort against an obstructed airway, usually from upper airway infection, tumor, or laryngospasm. Patients with NPPE generate very negative airway pressures, which augment transvascular fluid filtration and precipitate interstitial and alveolar edema. Pulmonary edema fluid collected from most patients with NPPE has a low protein concentration, suggesting hydrostatic forces as the primary mechanism for the pathogenesis of NPPE. Supportive care should be directed at relieving the upper airway obstruction by endotracheal intubation or cricothyroidotomy, institution of lung-protective positive-pressure ventilation, and diuresis unless the patient is in shock. Resolution of the pulmonary edema is usually rapid, in part because alveolar fluid clearance mechanisms are intact. In this review, we discuss the clinical presentation, pathophysiology, and management of negative-pressure or postobstructive pulmonary edema. Copyright © 2016 American College of Chest Physicians.

    Vulvar edema is a condition rarely reported and without defined treatment that may result in functional limitation. The aim of the report is to describe a case series of patients with disabling vulvar edema of different etiologies that were treated with manual lymphatic drainage (MLD) and multilayer compression therapy (MCT). Four cases of vulvar edema are described: one in a woman with cervical cancer; one in a woman in the postoperative period of bilateral adrenalectomy for pheocromocytoma; and two in pregnant women with preeclampsia. All cases were treated with MLD and MCT during hospitalization. Total resolution of the edema occurred in 2 to 5 d of treatment. The present case series is the first to report the use of the MLD and MCT in the successful management of female genital edema. This report suggests that the vulvar edemas for these four patients treated with MLD and MCT seem to resolve faster than expected based on previously reported untreated edemas or edemas treated with different therapeutic approaches.

    We qualitatively assessed the regional distribution of vasogenic edema in a case of postpartum eclampsia. Although diffusion-weighted imaging showed no abnormalities, bilateral high signal was seen on T2-weighted images and apparent diffusion coefficient (ADC) maps. ADC of 1.45 ± 0.10 mm 2 /s x 10 -3 for the posterior cerebral artery (PCA) territory and 1.22 ± 0.12 mm 2 /s x 10 -3 for the watershed areas were significantly higher than those in the territories of the anterior (0.85 ± 0.07 mm 2 /s x 10 -3 ) and middle cerebral (0.79 ± 0.06 mm 2 /s x 10 -3 )arteries (P < 0.05). The predilection of ADC changes within the PCA territory and in a previously undescribed watershed distribution supports the hypothesis that vasogenic edema in eclampsia is due to hypertension-induced failure of vascular autoregulation.

    Negative pressure pulmonary edema after acute upper airway obstruction is a well-described event, though infrequently diagnosed and reported. This report aimed at presenting a case of upper airway obstruction negative pressure pulmonary edema following acute upper airway obstruction characterized by pulmonary edema asymmetry, being more prominent in the right lung. A 4-year-old boy, 17 kg, phisical status ASA I submitted to combined tonsillectomy, adenoidectomy and turbinate cauterization under general anesthesia with sevoflurane/nitrous oxide/O2. Surgery duration was 90 minutes without complications. During anesthetic recovery and spontaneously breathing, patient reacted to tracheal tube, which was removed. Following, ventilatory efforts resulted in chest wall retraction without apparent air movement, being impossible to ventilate him with facial mask. Symptoms evolved to severe hypoxemia (50% SpO2) requiring reintubation. At this point, it was observed that the lung was stiffer and there were bilateral rales characterizing pulmonary edema. A chest X-ray showed diffuse bilateral infiltrates, right upper lobe atelectasis and marked pulmonary edema asymmetry (right greater than left). Patient was mechanically ventilated with PEEP for 20 hours when he was extubated. There was a progressive pulmonary edema improvement and patient was discharged 48 hours later. Negative pressure pulmonary edema (NPPE) is a rare event with high morbidity risk. It is often not diagnosed and requires from the anesthesiologist an updated knowledge and adequate management. It is usually bilateral, rarely unilateral, and exceptionally asymmetric as in this case. Most cases are treated by mechanical ventilation with PEEP or CPAP without any other therapy. The prognosis is favorable, with most cases recovering within the first 24 hours.

    Four patients of Greek ancestry had dominantly inherited cystoid macular edema. Characteristics of this syndrome include the following: an early onset and prolonged course of cystoid changes in the macula, followed by atrophy of the macula in later stages. Some patients also show leakage of fluorescein from the optic disc capillaries, subnormal EOG Lp/Dt ratios, elevated rod dark adaptation thresholds, red-green and blue-yellow color deficiencies, normal ERG findings, hyperopia, peripheral pigmentary retinopathy, and vitreous opacities. Dominantly inherited cystoid macular edema is a distinct genetic trait among the dominantly inherited macular dystrophies.

    Propofol is frequently used in the emergency department to provide procedural sedation for patients undergoing various procedures and is considered to be safe when administered by trained personnel. Pulmonary edema after administration of propofol has rarely been reported. We report a case of a 23-year-old healthy male who developed acute cough, hemoptysis and hypoxia following administration of propofol for splinting of a foot fracture. Chest radiography showed bilateral patchy infiltrates. The patient was treated successfully with supportive care. This report emphasizes the importance of this potentially fatal propofol-associated complication and discusses possible underlying mechanisms and related literature.

    Full Text Available Background: Annual pilgrimage (Yatra to the cave shrine of Shri Amarnath Ji′ is a holy ritual among the Hindu devotees of Lord Shiva. Located in the Himalayan Mountain Range (altitude 13,000 ft in south Kashmir, the shrine is visited by thousands of devotees and altitude sickness is reportedly common. Materials and Methods: More than 600,000 pilgrims visited the cave shrine in 2011 and 2012 with 239 recorded deaths. Thirty one patients with suspected altitude sickness were referred from medical centers en-route the cave to Sher-i-Kashmir Institute of Medical Sciences, a tertiary-care center in capital Srinagar (5,000 ft. The clinical features and the response to treatment were recorded. Results: Thirty-one patients (all lowlanders, 19 male; age 18-60 years, median 41 had presented with acute onset breathlessness of 1-4 days (median 1.9 d starting within 12-24 h of a rapid ascent; accompanied by cough (68%, headache (8%, dizziness and nausea (65%. Sixteen patients had associated encephalopathy. Clinical features on admission included tachypnea ( n = 31, tachycardia ( n = 23, bilateral chest rales ( n = 29, cyanosis ( n = 22 and grade 2-4 encephalopathy. Hypoxemia was demonstrable in 24 cases and bilateral infiltrates on radiologic imaging in 29. Ten patients had evidence of high-altitude cerebral edema. All patients were managed with oxygen, steroids, nifedipine, sildenafil and other supportive measures including invasive ventilation ( n = 3. Three patients died due to multiorgan dysfunction. Conclusions: Altitude sickness is common among Amaranath Yatris from the plains and appropriate educational strategies should be invoked for prevention and prompt treatment.

  13. Therapeutic implications of melatonin in cerebral edema.

    Cerebral edema/brain edema refers to the accumulation of fluid in the brain and is one of the fatal conditions that require immediate medical attention. Cerebral edema develops as a consequence of cerebral trauma, cerebral infarction, hemorrhages, abscess, tumor, hypoxia, and other toxic or metabolic factors. Based on the causative factors cerebral edema is differentiated into cytotoxic cerebral edema, vasogenic cerebral edema, osmotic and interstitial cerebral edema. Treatment of cerebral edema depends on timely diagnosis and medical assistance. Pragmatic treatment strategies such as antihypertensive medications, nonsteroidal anti-inflammatory drugs, barbiturates, steroids, glutamate and N-methyl-D-aspartate receptor antagonists and trometamol are used in clinical practice. Although the above mentioned treatment approaches are being used, owing to the complexity of the mechanisms involved in cerebral edema, a single therapeutic strategy which could ameliorate cerebral edema is yet to be identified. However, recent experimental studies have suggested that melatonin, a neurohormone produced by the pineal gland, could be an effective alternative for treating cerebral edema. In animal models of stroke, melatonin was not only shown to reduce cerebral edema but also preserved the blood brain barrier. Melatonin's beneficial effects were attributed to its properties, such as being a potent anti-oxidant, and its ability to cross the blood brain barrier within minutes after its administration. This review summarizes the beneficial effects of melatonin when used for treating cerebral edema.

    Full Text Available Various aberrant muscles and fibro-tendinous structures have been identified in the anterior wrist, some of them blamed to be possible causes for neurovascular compression syndromes. Herewith, we describe such an intriguing structure related to the flexor carpi ulnaris muscle. During routine dissection of both upper limbs of an adult cadaver, an interesting crescent-shaped fibro-tendinous structure was identified bilaterally, arising broadly from the lateral side of the distal tendon of the flexor carpi ulnaris. This aberrant structure arched over the ulnar artery and nerve before they enter the canal of Guyon and the median nerve just before the carpal tunnel. Further distally, the fibro-tendinous arch narrowed and interlaced with the flexor retinaculum and palmar aponeurosis longitudinal fibres. In this case there was also concomitant bilateral absence of the palmaris longus muscle. Because this aberrant fibro-tendinous arch has very close relations to the median nerve and ulnar nerve and artery in the wrist, it may possibly cause neurovascular compression during some muscle activity.Varios músculos y estructuras fibro-tendinosas aberrantes se han identificado en la parte anterior de la muñeca, muchas de las cuales se considera que pueden causar síndromes de compresión neurovascular. A continuación describimos una tal estructura relacionada con el músculo flexor carpi ulnaris. Durante disecciones de rutina de ambos miembros superiores de cadáveres de adultos fue descubierta una estructura fibro-tendinosa con forma de medialuna en ambos miembros originando de la parte lateral del tendón distal del flexor carpi ulnaris. Esta estructura formaba un arco pasando sobre y cubriendo la arteria y el nervio ulnar antes de que entren en el canal de Guyon, y sobre el nervio mediano justo antes de que entre en el canal carpal. Este arco fibro-tendinoso seguía estrechándose hasta entrelazarse con el ligamento transverso del carpo y las fibras

    Mumps virus infection primarily affects the salivary glands and may incur various complications. Laryngeal edema is such a rare complication that few adult cases have been reported. We report the first known pediatric patient with mumps with laryngeal edema. An 8-year-old boy developed dyspnea after a rapidly progressive swelling of his face and neck. Laryngoscopy revealed edematous changes in the supraglottic and subglottic regions, and computed tomography confirmed significant laryngeal edema in addition to swelling of the cervical soft tissue and the salivary glands. Laboratory findings revealed a high serum amylase level and confirmed the diagnosis of mumps. Intravenous steroid administration alleviated the dyspnea, although the patient required temporary tracheal intubation to maintain airway patency. He did not need tracheotomy and did not experience any other complications. Laryngeal edema must be regarded as a rare, potentially life-threatening complication of mumps. When mumps is diagnosed with significant swelling of the neck, an emergency airway should be established to prevent airway obstruction.

    Full Text Available A pneumonectomia, embora seja tecnicamente simples, está associada a alta incidência de complicações (cerca de 60%. As complicações respiratórias correspondem a aproximadamente 15% deste total. A mortalidade global dessa cirurgia é de 8,6%, mas em presença de complicações respiratórias, a taxa de mortalidade chega a 30%. O edema pulmonar pós-pneumonectomia é uma complicação rara (3% a 5%, mas muito grave, sendo fatal na maioria dos casos. Foi descrito pela primeira vez há pouco mais de vinte anos mas, apesar da gravidade alarmante, pouco sabemos acerca de sua fisiopatologia, embora muitas hipóteses tenham sido levantadas. Uma vez instalado, nenhuma medida é comprovadamente eficaz no seu tratamento. Vários fatores de risco estão associados ao aparecimento do edema pulmonar pós-pneumonectomia, dentre os quais a sobrecarga hídrica, que foi o primeiro fator evitado. Entretanto, muitos trabalhos mostram não haver relação direta entre o volume recebido e o desenvolvimento do edema. A prevenção é a melhor forma de evitá-lo e deve ser realizada de maneira multifatorial, envolvendo toda a equipe médica, desde o momento da anestesia até os cuidados cirúrgicos e na terapia intensiva. No entanto, tão importante quanto a prevenção, é a suspeita clínica precoce, identificando os pacientes em risco para essa grave complicação.Although pneumonectomy is a technically simple procedure, it has been associated with a high (60% incidence of complications.

    Full Text Available Background/Aim. The effect of drugs leaves permanent consequences on the brain, organic in type, followed by numerous manifestations, and it significantly affects the development of mental dysfunctions. The clinicians are often given a task to estimate a patient’s personality during treatment or during experts estimate of a drug addict. The aim of this research was to determine the differences, if any, in characteristics of addicts experience and personality traits in drug addicts with or without cerebral edema. Methods. The research was conducted on a sample of 252 male drug addicts, the average age of 23.3 (SD = 4.3 years. Cerebral edema was confirmed on magnetic resonance (MR images of the brain performed during the treatment of the addicts. The participants were tested by the psychologists using Minnesota Multiphasic Personality Inventory (MMPI-201 test, and the data were processed using canonical discriminate analysis within the SPSS program. The dependent variable in the study was cerebral edema. A block of independent variables, designed for the requirements of this study, consisted of two subgroups. The first one consisted of 12 variables describing the relevant characteristics of drug abuse. The second subgroup consisted of 8 psychopathological tendencies in the personality defined by the mentioned test. Results. Cerebral edema was confirmed in 52 (20.63% of the drug addicts. The differences between the groups of drug addicts with and without cerebral edema were determined in the following: the time span of taking drugs (0.301, use of alcohol parallel with drugs (0.466, and treatment for addiction (0.603. In the drug addicts with a cerebral edema, MMPI-201 confirmed the increase in the scales for hypochondria, psychopathic deviations and psychastenia, and the decrease in the scales for schizophrenia and depression. Conclusion. Our study confirmed a possible connection between cerebral edema and personality traits in a number of the

    Full Text Available Congenital bilateral absence of the vas deferens (CBAVD is a form of male infertility in which mutations in the cystic fibrosis transmembrane conductance regulator (CFTR gene have been identified. Here we identify different mutations of CFTR and the poly-T variant of intron 8 (IVS8 in Argentine patients and analyze sweat test values and clinical characteristic related to Cystic Fibrosis (CF. For counseling purposes the two most frequent mutations in Argentine CF population: DF508 and G542X were screened in wives. In all cases, it was possible to reduce the risk of CF/CBAVD descendants in these couples because none of the mutation were found in the 36 samples. Eight patients (23% showed abnormal chloride values (> 60 mmol/l. A second group of 6 patients (18% had borderline values of sweat chloride (40-59 mmol/l. We defined another group with 6 patients (18%, with normal sweat chloride levels (30-39 mmo/l and a fourth group of 14 (41% patients with sweat chloride below 30 mmol/l. DF508, the most frequent CF mutation in the Argentine population, was found on 15 of the 72 chromosomes (21%, R117H mutation was detected on 2 of 62 chromosomes (3%. Only one R347P allele was found on 28 chromosomes analyzed (2%. On a sample of 27 patients, IVS8 analysis showed a frequency of 6/56 chromosomes (11% of 5T allele. Even though these findings present an improvement in the detection of mutations related to clinical correlations in Argentine CBAVD population, the search for other common and uncommon mutations should be continued.La ausencia bilateral congénita de vasos deferentes (CBAVD es una forma de infertilidad masculina en la que se han identificado mutaciones en el gen de la conductancia transmembrana de la fibrosis quística (CFTR.

    2015-01-01

    We describe a case of 17 year-old male with a nasopharyngeal rhabdomyosarcoma who developed postobstructive pulmonary edema (POPE) after removing the endotracheal tube following biopsy. He developed muffled voice, rhinorrhea, dysphagia, odynophagia, and difficulty breathing through nose and weight loss of 20 pounds in the preceding 2 months. A nasopharyngoscopy revealed a fleshy nasopharyngeal mass compressing the soft and hard palate. Head and neck MRI revealed a large mass in the nasopharynx extending into the bilateral choana and oropharynx. Biopsy of the mass was taken under general anesthesia with endotracheal intubation. Immediately after extubation he developed oxygen desaturation, which did not improve with bag mask ventilation with 100% of oxygen, but improved after a dose of succinylcholine. He was re-intubated and pink, frothy fluid was suctioned from the endotracheal tube. Chest radiograph (CXR) was suggestive of an acute pulmonary edema. He improved with mechanical ventilation and intravenous furosemide. His pulmonary edema resolved over the next 24 h. POPE is a rare but serious complication associated with upper airway obstruction. The pathophysiology of POPE involves hemodynamic changes occurring in the lung and the heart during forceful inspiration against a closed airway due to an acute or chronic airway obstruction. This case illustrates the importance of considering the development of POPE with general anesthesia, laryngospasm and removal of endotracheal tube to make prompt diagnosis and to initiate appropriate management.

    Pulmonary edema is known to develop in users of heroin and methadone. Its association with cocaine use is usually a postmortem finding. There has been only 1 report of pulmonary edema being diagnosed clinically after cocaine use. In that case the cocaine was used intravenously, and death occurred within 3 h after the onset of symptoms. Here we describe a patient who developed acute pulmonary edema after smoking "freebase" cocaine. The pulmonary edema resolved spontaneously within 72 h. The cause of the acute reversible pulmonary edema was probably related to both pressure- and permeability-related changes.

    We present an unusual ocular complication during the perioperative period, bilateral orbital edema in an otherwise healthy child after an outpatient surgical procedure. Ocular complications under general anesthesia remain a rare event. When periorbital edema is present, the appropriate work-up includes ruling out the potential for an allergic event by reviewing the medications administered and serum tryptase testing. Ophthalmology consultation should be considered to exclude pathology native to the eye itself. An allergist may assist in confirming a diagnosis and for allergic testing, if indicated. In our patient, the eventual diagnosis of exclusion was that of a localized reaction to the cellophane-based eye tape.

    Children with either acute or chronic upper airway obstruction are at risk for postobstructive pulmonary edema. Appropriate diagnosis and management are important in leading to a good outcome for the patient. We describe 2 cases of postobstructive pulmonary edema caused by brief acute upper airway obstruction. In the first case, a child choked on a hot dog and in the second on a "jawbreaker." Both children developed symptoms of complete upper airway obstruction and were managed initially with the Heimlich maneuver and subsequently developed increased work of breathing associated with an oxygen requirement after relief of the obstruction. Both children were managed in the pediatric intensive care unit and were discharged after resolution of symptoms without sequelae.

    Full Text Available Acute hemorrhagic edema of infancy is a rare form of leukocytoclastic vasculitis. Mostly it appears under three years of age and is characterized by purpuric skin lesions, fever and edema. A three years-old boy, who has cough and coryzea was admitted to our clinic for fever and red spots on legs and arms. In physical examination; ecimotic skin lesions on right ear, face, arms, dorsal of the hands, buttocks, legs and dorsal of the feet were found. In the laboratory tests acute phase reactants were elevated and blood coagulation tests were in normal range. Hepatit A,B,C and TORCH markers were negative. Punch biopsy obtained from gluteal area showed leukositoclastic vasculity. Focal fibrinogen accumulation was detected by immun fluorescent microscopy. Regression on lesions was not observed despite supportive therapy, so prednisolone (1 mg/kg/day therapy was started. On the third day of the steroid therapy, complete recovery was achived.

    Pulmonary edema occurs when fluid flux into the lung interstitium exceeds its removal, resulting in hypoxemia and even death. Noncardiogenic pulmonary edema (NPE) generally results when microvascular and alveolar permeability to plasma proteins increase, one possible etiology being oxidant injury. Reactive oxygen and nitrogen species (RONS) can modify or damage ion channels, such as epithelial sodium channels, which alters fluid balance. Experimental systems in which either RONS are increased or protective antioxidant mechanisms are decreased result in alterations of epithelial sodium channel activity and support the hypothesis that RONS are important in NPE. Both basic and clinical studies are needed to critically define the RONS-NPE connection and the capacity of antioxidant therapy (either alone or as a supplement to β-agonists) to improve patient outcome.

    2012-01-01

    Full Text Available Bilateral sixth nerve paresis following closed head injury, though rare, is a known entity. However, delayed-onset post-traumatic bilateral abducens paresis is extremely rare. We present two cases. The first patient had onset of bilateral abducens paresis 2 weeks after closed head injury and the second patient after 3 days. The cause in the former was detected to be chronic subdural hematoma and in the latter is speculated to be edema/ischemia due to injury to soft tissue structures housing these nerves. The delayed onset of bilateral abducens paresis following head injury may vary according to the cause. There may be another mechanism of injury apart from direct trauma. Though rare, it needs to be evaluated and may have a treatable cause like elevated intracranial pressure.

    Full Text Available A young female presenting with right flank pain, fever, raised creatinine and bilateral hydronephrosis was treated with antibiotics elsewhere, with presumptive diagnosis of bilateral pyelonephritis. She had partial relief in symptoms and her creatinine level showed an improvement. Three months later during evaluation at our center she had anuria, hypertensive crisis and pulmonary edema which were managed with emergency bilateral percutaneous nephrostomies. Cross-sectional imaging and ureteroscopy suggested bilateral synchronous intramural mid-ureteric lesions as underlying pathology. Histopathology of the ureteric segments during laparotomy revealed caseating granulomas suggestive of tuberculosis. This clinical presentation has not been previously described in urinary tuberculosis.

    A 61 year-old man presented with progressive shortness of breath. Computed tomography scan of the chest showed diffuse ground glass infiltrates and dilated pulmonary vessels in the right lung in addition to bilateral pulmonary masses with obstruction of the left main pulmonary bronchus. The patient underwent bronchoscopy with destruction of the tumor obstructing the left main pulmonary bronchus, resulting in clinical improvement and resolution of the right pulmonary infiltrates. We hypothesize that the patient developed right pulmonary edema secondary to hypoxic vasoconstriction of the left lung. This case suggests a rare mechanism of unilateral pulmonary edema and supports inclusion of pulmonary edema in the differential diagnosis of unilateral pulmonary infiltrates in the setting of contralateral bronchial obstruction.

    Terminology of persistent diabetic macular edema has been initially reserved to cases unresponsive to conventional laser photocoagulation according to ETDRS criteria. While knowledge about pathophysiology of macular edema evolved and new drugs became available, the terminology of persistent diabetic macular edema expanded to include resistance to most current therapies. The purpose of this paper is to review medical and surgical options in the treatment of such difficult cases according to literature data and personal experience.

  18. Bone marrow edema in sports: General concepts

    This paper will discuss the value of medical imaging in the detection and follow-up of bone marrow edema (BME), resulting from acute and chronic trauma in sports. MR imaging is the only imaging technique that allows direct evaluation of bone marrow edema in sports medicine. The use of fat suppressed T2-weighted or STIR images is particularly appropriate to detect bone marrow edema. The extent of bone marrow edema reflects the biomechanics of trauma. Compressive forces between two bony structures will result in extensive areas of bone marrow edema, whereas distraction forces provoke more subtle areas of bone marrow edema at the insertion of supporting structures of joints. In most clinical situations, a combination of compression and distraction forces is present, causing a complex pattern of bone marrow edema. A meticulous pattern approach of the distribution of these bone marrow changes around a joint can reveal in most instances the underlying mechanism of trauma. This may be helpful to analyze which joint supporting structures may be at risk. In the acute setting, plain radiography and CT scan may have an additional role in the detection of small avulsion fractures occurring at the site of minor areas of bone marrow edema. The clinical significance and natural history of bone marrow edema is still a matter of debate

    Eight (23%) of 35 children with acute pericardial effusions due to infection or juvenile rheumatoid arthritis (JRA) had associated transient pulmonary edema demonstrated on plain chest radiographs. The presence or absence of radiographic pulmonary edema correlated well with clinical and hemodynamic parameters in patients with JRA but not in those with infectious pericarditis. There was no definite relationship between radiographic edema and amount of pericardial fluid as estimated echocardiographically or removed at pericardiocentesis. Rapidity of pericardial fluid accumulation could not be assessed in this study. Children of young age with underlying JRA were the most likely subjects to have radiographic pulmonary edema in conjunction with an acute pericardial effusion. (orig.)

    Acute carbon monoxide poisoning has frequently occurred in Korean, because of the coal briquette being widely used as fuel in Korean residences. Carbon monoxide poisoning has been extensively studied, but it has been sparsely reported that pulmonary edema may develop in acute CO poisoning. We have noticed nine cases of pulmonary edema in acute CO poisoning last year. Other possible causes of pulmonary edema could be exclude in all cases but one. The purpose of this paper is to describe nine cases of pulmonary edema complicated in acute CO poisoning and discuss the pathogenesis and the prognosis

    Cerebral edema causes intracranial hypertension (ICH) which leads to severe outcome of patients in the clinical setting. Effective anti-edema therapy may significantly decrease the mortality in a variety of neurological conditions. At present drug treatment is a cornerstone in the management of cerebral edema. Osmotherapy has been the mainstay of pharmacologic therapy. Mannitol and hypertonic saline (HS) are the most commonly used osmotic agents. The relative safety and efficacy of HS and mannitol in the treatment of cerebral edema and reduction of enhanced ICP have been demonstrated in the past decades. Apart from its osmotic force, HS exerts anti-edema effects partly through inhibition of Na(+)-K(+)-2Cl(-) Cotransporter-1 (NKCC1) and aquaporin 4 (AQP4) expression in astrocytes. Melatonin may also reduce brain edema and exert neuroprotective effect on several central nervous system diseases through inhibition of inflammatory response. The inhibitors of Na/H exchanger, NKCC and AQP4 may attenuate brain edema formation through inhibition of excessive transportation of ion and water from blood into the cerebral tissue. In this review we survey some of the most recent findings in the drug treatment of brain edema focusing on the use of osmotherapy, melatonin and inhibitors of ion cotransporters and water channels. A better understanding of the molecular mechanism of these agents would help to improve in the clinical management of patients with brain edema.

    A 70-year-old female developed respiratory failure due to pharyngolaryngeal edema after posterior occipito-cervical fusion. She had a history of total thyroidectomy with bilateral neck dissection for advanced thyroid cancer associated with multiple lung metastases. However, her general condition was good, and she was not in cachexia. Her pulmonary function test revealed %VC of 54% and %FEV1.0 of 79%. This posterior occipito-cervical fusion was necessary for pain relief. Twenty-four hours after surgery she suddenly showed dyspnea, requiring tracheal intubation, and was supported by mechanical ventilation. The pharyngolaryngeal edema was recognized with bronchoscopy from the lower larynx with arytenoid region to nasal choana. In several days she recovered from pharyngolaryngeal edema and was extubated. She was discharged from ICU after close observation for 24 hours after extubation. She developed respiratory distress again due to difficulty in sputum expectoration, resulting in emergency tracheostomy an the floor at midnight. In this case, pharyngolaryngeal edema may have been caused by disturbance of lymphatic flow due to posterior occipito-cervical fusion in a patient with a past history of bilateral neck dissection. We also reviewed the literature in this report.

    Full Text Available Brain edema is a potentially fatal pathological state that occurs after brain injuries such as stroke and head trauma. In the edematous brain, excess accumulation of extracellular fluid results in elevation of intracranial pressure, leading to impaired nerve function. Despite the seriousness of brain edema, only symptomatic treatments to remove edema fluid are currently available. Thus, the development of novel anti-edema drugs is required. The pathogenesis of brain edema is classified as vasogenic or cytotoxic edema. Vasogenic edema is defined as extracellular accumulation of fluid resulting from disruption of the blood-brain barrier (BBB and extravasations of serum proteins, while cytotoxic edema is characterized by cell swelling caused by intracellular accumulation of fluid. Various experimental animal models are often used to investigate mechanisms underlying brain edema. Many soluble factors and functional molecules have been confirmed to induce BBB disruption or cell swelling and drugs targeted to these factors are expected to have anti-edema effects. In this review, we discuss the mechanisms and involvement of factors that induce brain edema formation, and the possibility of anti-edema drugs targeting them.

    Noncardiogenic pulmonary edema is an important cause of respiratory disease in dogs and cats but few reports describe its radiographic appearance. The purpose of this retrospective case series study was to describe radiographic findings in a large cohort of dogs and cats with presumed noncardiogenic pulmonary edema and to test associations among radiographic findings versus cause of edema. Medical records were retrieved for dogs and cats with presumed noncardiogenic edema based on history, radiographic findings, and outcome. Radiographs were reviewed to assess lung pattern and distribution of the edema. Correlation with the cause of noncardiogenic pulmonary edema was evaluated with a Fisher's exact test. A total of 49 dogs and 11 cats were included. Causes for the noncardiogenic edema were airway obstruction (n = 23), direct pulmonary injury (n = 13), severe neurologic stimulation (n = 12), systemic disease (n = 6), near-drowning (n = 3), anaphylaxis (n = 2) and blood transfusion (n = 1). Mixed, symmetric, peripheral, multifocal, bilateral, and dorsal lung patterns were observed in 44 (73.3%), 46 (76.7%), 55 (91.7%), 46 (76.7%), 46 (76.7%), and 34 (57.6%) of 60 animals, respectively. When the distribution was unilateral, pulmonary infiltration involved mainly the right lung lobes (12 of 14, 85.7%). Increased pulmonary opacity was more often asymmetric, unilateral, and dorsal for postobstructive pulmonary edema compared to other types of noncardiogenic pulmonary edema, but no other significant correlations could be identified. In conclusion, noncardiogenic pulmonary edema may present with a quite variable radiographic appearance in dogs and cats. © 2016 American College of Veterinary Radiology.

    Peritumoral edema associated with 28 meningiomas was studied. The results of radiological investigation, using MRI, CT, and angiography, and histological studies were described and correlated with each other in order to clarify the mechanism of peritumoral cerebral edema production. Extensive peritumoral edema was recognized when the venous sinus or cortical veins, especially the superficial and deep Sylvian veins, were invaded and/or compressed markedly by the tumor. Therefore, large tumors (more than 5 cm in diameter) which were located in the parasagittal area and the middle cranial fossa had a tendency to be associated with extensive peritumoral edema. The posterior fossa meningiomas were associated with small edema because there were rich venous channels in the posterior fossa. Although there have been several reports that the peritumoral edema of meningioma would be produced by the vessels of the tumor itself and would migrate through the tumor capsule into the surrounding brain tissue, and although mechanical factors alone are not sufficient to explain peritumoral edema production, we would like to postulate that the longstanding mechanical compression of venous circulation by the meningioma might be an important factor in the production of the peritumoral cerebral edema.

    Early detection of pulmonary edema is vital to appropriate fluid management following subarachnoid hemorrhage (SAH). Lung ultrasound (LUS) has been shown to accurately identify pulmonary edema in patients with acute respiratory failure (ARF). Our objective was to determine the accuracy of daily screening LUS for the detection of pulmonary edema following SAH. Screening LUS was performed in conjunction with daily transcranial doppler for SAH patients within the delayed cerebral ischemia (DCI) risk period in our neuroICU. We reviewed records of SAH patients admitted 7/2012-5/2014 who underwent bilateral LUS on at least 5 consecutive days. Ultrasound videos were reviewed by an investigator blinded to the final diagnosis. "B+ lines" were defined as ≥3 B-lines on LUS. Two other investigators blinded to ultrasound results determined whether pulmonary edema with ARF (PE-ARF) was present during the period of evaluation on the basis of independent chart review, with a fourth investigator performing adjudication in the event of disagreement. The diagnostic accuracy of B+ lines for the detection of PE-ARF and RPE was determined. Of 59 patients meeting criteria for inclusion, 21 (36%) had PE-ARF and 26 (44%) had B+ lines. Kappa for inter-rater agreement was 0.821 (p pulmonary edema following SAH and may assist with fluid titration during the risk period for DCI.

    Postoperative cerebral edema around a deep brain stimulation (DBS) electrode is an uncommon reported complication. The goal of this study was to identify instances of postoperative edema based on clinical presentation, and to remark on their management. A retrospective chart review was performed on all patients who underwent DBS electrode implantation over a 3-year period. Routine CT imaging on postoperative day (POD) 1 was negative. Patients were identified based on clinical neurological changes, leading to imaging and subsequent diagnosis. Five of 145 patients (3.4%) presented with new neurological symptoms from POD 1 to 14, which were confirmed by CT imaging to show perilead and/or subcortical edema around 6 of 281 electrodes (2.1%). Four of 5 patients had unilateral edema despite bilateral implantation. Clinical presentations varied widely. Two patients presenting on POD 1 with deteriorating conditions required longer inpatient stays with supportive measures than those presenting later (p = 0.0002). All patients were treated with corticosteroids and returned to baseline by 3 months after surgery. Acute instances of DBS lead edema may occur as early as POD 1 and can rapidly progress into profound deficits. Treatment with supportive care and corticosteroids is otherwise identical to those cases presenting later. © 2017 S. Karger AG, Basel.

    Full Text Available Propofol is frequently used in the emergency department to provide procedural sedation for patients undergoing various procedures and is considered to be safe when administered by trained personnel. Pulmonary edema after administration of propofol has rarely been reported. We report a case of a 23-year-old healthy male who developed acute cough, hemoptysis and hypoxia following administration of propofol for splinting of a foot fracture. Chest radiography showed bilateral patchy infiltrates. The patient was treated successfully with supportive care. This report emphasizes the importance of this potentially fatal propofol-associated complication and discusses possible underlying mechanisms and related literature. [West J Emerg Med. 2014;15(7:–0.

    To analyze the demographics, risk factors, clinical and microbiological characteristics of cases of bilateral simultaneous infective keratitis. In this retrospective case series, patients with clinical evidence of bilateral simultaneous infective keratitis were identified from January 1, 2011 to August 31, 2016. Demographics, risk factors, clinical and microbiological characteristics, and treatment outcomes were analyzed. Five patients (ten eyes) with bilateral simultaneous infective keratitis were identified. The mean age was 32.8 years (SD,±8.8; range, 24-44). All the patients were disposable soft contact lens wearers before presentation. The average size of the infiltrate was 4.76mm 2 (SD±9.0; range, 0.2-31.34). A total of 4 types of bacteria were isolated, with Pseudomonas aeruginosa being the most frequently isolated bacteria involving 5 eyes of four patients. Infection resolved with medical treatment in 9 eyes, 1 patient required therapeutic corneal transplantation for impending corneal perforation. The average time taken for infection to resolve was 6.7days (SD±4.5; range, 2-16). In this case series, the most common risk factor of bilateral simultaneous microbial keratitis was use of soft disposable contact lens and the most commonly isolated bacteria was Pseudomonas aeruginosa. Bilateral simultaneous infective keratitis is uncommon and is a serious complication of contact lens use in immunocompetent adult patients. Copyright © 2017 British Contact Lens Association.

    In a series of 56 staged bilateral carotid endarterectomies, new neurologic symptoms developed in 5% and 20% following the first and second procedure, respectively. All complications were transient or minor. The incidence of postendarterectomy hypertension was significantly higher following...... the second procedure, when operations were staged less than 3 weeks apart. A correlation between these hypertensive episodes and the occurrence of new neurologic symptoms could not be shown. However, as this correlation has been proved in several other reports, bilateral carotid endarterectomy is advised...... to be staged at least 3 weeks apart. In addition, a conservative attitude towards contralateral asymptomatic lesions is proposed....

    To the editor:--A 29-year-old white woman was seen April 17, 1967, with a severe angioneurotic edema of the face which had developed suddenly. She had taken aspirin for the two previous days and ethynodiol diacetate with mestranol (Ovulen) for 15 days. Treatment with epinephrine and dexamethasone administered parenterally and diphenhydramine orally did not benefit. Oral contraceptive thereapy was discontinued, and the edema subsided five days later. On April 25, she was asymptomatic. Aspirin had produced no ill effect, and oral contraceptive therapy was started again. After four days edema of the uvula and soft palate appeared, and again medication did not give relief. The edema subsided after a few days during which the patient abstained from cosmetics, tooth pastes, and all allergenic dietary items. Later she resumed all foods and contactants, but has taken no oral contraceptives, and has remained asymptomatic.

    2015-10-01

    There have been two major theories surrounding the development of edema in nephrotic syndrome (NS), namely, the under- and overfill hypotheses. Edema is one of the cardinal features of NS and remains one of the principal reasons for admission of children to the hospital. Recently, the discovery that proteases in the glomerular filtrate of patients with NS are activating the epithelial sodium channel (ENaC), resulting in intrarenal salt retention and thereby contributing to edema, might suggest that targeting ENaC with amiloride might be a suitable strategy to manage the edema of NS. Other potential agents, particularly urearetics and aquaretics, might also prove useful in NS. Recent evidence also suggests that there may be other areas involved in salt storage, especially the skin, and it will be intriguing to study the implications of this in NS.

    Cervical spondylolysis, which is defined as a cleft between the superior and inferior articular facets of the articular pillar, is a rare condition. The sixth cervical vertebra (C6) is the level most commonly affected. Cases involving C2, C3, C4, or C5 have also been reported. However, to date, no case of C7 spondylolysis has been reported. To present a rare case of bilateral spondylolysis of the seventh cervical vertebra (C7) in a 58-year-old man. A case report. A 58-year-old man visited our hospital with chronic posterior neck pain radiating to the left upper extremity. Magnetic resonance imaging (MRI) study revealed left foraminal disc herniations at C5-C6 and C6-C7. Cervical spondylolysis involving C7 was discovered incidentally during computed tomography (CT)-guided transforaminal steroid injection. Plain radiographs, CT images, and MRIs were reviewed thoroughly once again. The patient's symptoms were relieved after he received CT-guided transforaminal steroid injections. Plain radiographs revealed a radiolucent defect in the articular pillar and cleft at the spinous process of C7. Computed tomography confirmed bilateral spondylolysis and spina bifida occulta of the C7 vertebra. Magnetic resonance imaging revealed absence of edema, which was suggestive of a chronic lesion. Involvement of C7 is not exceptional in a case of cervical spondylolysis. Copyright © 2010 Elsevier Inc. All rights reserved.

    A 63-year-old woman presented with radionecrosis in the bilateral temporal lobes manifesting as dementia about 30 years after undergoing conventional radiotherapy for pituitary adenoma. Computed tomography and magnetic resonance (MR) imaging showed edema and cystic lesions in both temporal lobes. The mass in the left temporal lobe was excised. MR imaging 12 days after surgery showed reduced edema. Her dementia had improved. Radionecrosis usually occurs between several months and a few years after radiotherapy. The incidence of radionecrosis is estimated as 5%, but may be higher with longer follow-up periods. Clinical reports have suggested that larger total doses of radiation are associated with earlier onset of delayed necrosis and the fractional dose is the most significant factor causing cerebral radionecrosis. Radionecrosis can occur long after conventional radiotherapy or stereotactic radiosurgery using a linac-based system or a gamma knife unit. (author)

    Imaging findings of bilateral pulmonary vein atresia have not been described. To describe cardiac CT findings and clinical outcomes of bilateral pulmonary vein atresia. Three newborns with bilateral pulmonary vein atresia were encountered at our institution during a period of 8 years. We evaluated prenatal echocardiographic findings, clinical presentations, postnatal echocardiographic findings, chest radiographic findings, cardiac CT findings and clinical outcomes. All newborns presented immediately after birth with severe cyanosis, respiratory distress and acidosis that were unresponsive to medical management. Prenatal and postnatal echocardiographic studies and chest radiography were misleading, inconclusive or nonspecific in making the diagnosis in these children; however cardiac CT clearly demonstrated atresia of the bilateral pulmonary veins with multiple small mediastinal collateral veins and pulmonary edema. Surgical treatments were not feasible for this anomaly. Their clinical outcomes were universally dismal and all infants died within 3 days. Cardiac CT provides an accurate diagnosis of bilateral pulmonary vein atresia and leads to prompt treatment decision in these children. (orig.)

There was no additional specific findings for each cancer in bilateral breast cancers which was different from unilateral cancers. Therefor, in the patients with unilateral breast cancer, possibility of the second lesion in the contralateral side must be considered and a close follow up observation should be done for at least 3 years

    Full Text Available ANTECEDENTES: el edema macular diabético constituye la causa más frecuente de baja visión en personas con retinopatía diabética. En los diabéticos con edema macular diabético severo o difuso, la fotocoagulación con láser no ha brindado los resultados deseados. OBJETIVOS: revisar el estado actual del uso del acetato de triamcinolona por vía intravítrea en los pacientes con esa enfermedad. DESARROLLO: el acetato de triamcinolona es un corticoide con una potente acción antiinflamatoria y antiangiogénica, que consigue estabilizar la barrera hematorretiniana e inhibir la angiogénesis, de ahí que se ha empleado en el tratamiento del edema macular diabético, donde el daño de la barrera hematorretiniana y la liberación de factores angiogénicos en respuesta a la hipoxia están implicados fuertemente en la patogénesis de este tipo de edema. La administración intravítrea en diversas dosificaciones, y no en pocas ocasiones en forma repetida, han mostrado resultados un tanto controversiales al comparar el efecto beneficioso que produce el acetato de triamcinolona, con la corta duración de su efecto y las preocupaciones relacionadas con las complicaciones (hipertensión ocular, endoftalmitis, hemorragia vítrea, etc. relacionadas con las reinyecciones. Actualmente se ensayan dispositivos que liberan el acetato de triamcinolona de forma lenta y prolongan su efecto, para encontrar una estrategia de tratamiento más razonable y que sus efectos terapéuticos sean siempre superiores a los efectos indeseados. CONCLUSIONES: el tratamiento con acetato de triamcinolona constituye una alternativa en la mejoría del edema macular diabético, aunque estudios prospectivos y con período de seguimiento largo son necesarios para llegar a resultados más consistentes.BACKGROUNDS: diabetic macular edema is the more frequent cause of low grade vision in persons presenting with diabetic retinopathy.

    To report an human immunodeficiency virus-positive patient undergoing therapy for cryptococcal meningitis who developed progressive optic disc edema that was steroid responsive. Observational case report. One month after commencing antifungal treatment for cryptococcal meningitis, the patient developed bilateral, progressive, recurrent optic disc edema with subretinal fluid that coincided with initiation of highly active antiretroviral therapy and recovery of CD4 cell counts. Lumbar puncture revealed normal opening pressure, and cerebrospinal fluid showed no recurrence of cryptococcal infection. There was no evidence of uveitis. The patient rapidly improved with a 5-day course of high-dose intravenous methylprednisolone. Recurrent optic disc edema with loss of vision after treatment of cryptococcal meningitis in the setting of normal intracranial pressure may represent a unique manifestation of immune reconstitution inflammatory syndrome localized to the optic nerve without uveitis. This is consistent with the temporal relationship between starting highly active antiretroviral therapy, CD4 count recovery, and the development of progressive disc edema in the study patient. Isolated optic nerve inflammation as a manifestation of immune reconstitution inflammatory syndrome has not been widely reported.

    Peritumoral edema associated with 28 meningiomas was studied. The results of radiological investigation, using MRI, CT, and angiography, and histological studies were described and correlated with each other in order to clarify the mechanism of peritumoral cerebral edema production. Extensive peritumoral edema was recognized when the venous sinus or cortical veins, especially the superficial and deep Sylvian veins, were invaded and/or compressed markedly by the tumor. Therefore, large tumors (more than 5 cm in diameter) which were located in the parasagittal area and the middle cranial fossa had a tendency to be associated with extensive peritumoral edema. The posterior fossa meningiomas were associated with small edema because there were rich venous channels in the posterior fossa. Although there have been several reports that the peritumoral edema of meningioma would be produced by the vessels of the tumor itself and would migrate through the tumor capsule into the surrounding brain tissue, and although mechanical factors alone are not sufficient to explain peritumoral edema production, we would like to postulate that the longstanding mechanical compression of venous circulation by the meningioma might be an important factor in the production of the peritumoral cerebral edema.

    Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968—May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V—Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed. ImagesFig. 1Fig. 4Fig. 6Fig. 7 PMID:4845653

    2011-05-16

    Supernumerary teeth are teeth in excess of the normal series occurring in any region of the dental arch. They are located mostly in the anterior maxillary region and are classified according to their location and morphology. The tuberculate type of supernumerary tooth possesses more than one cusp or tubercle (barrel shaped). It is rare to find bilateral tuberculate supernumerary teeth in the premaxillary region and when found they rarely erupt. This report describes a 13-year-old boy with erupted palatally placed bilateral tuberculate supernumerary teeth. The presence of these supernumerary teeth led to the labial displacement and rotations of the anterior maxillary teeth. The treatment involved extraction of the supernumerary teeth and a referral for orthodontic management of the crowding, displacement and rotations. The occurrence of erupted palatally placed tuberculate anterior teeth in this case is a rare experience. However, the associated orthodontic problems are within familiar spectrum.

    Twenty children with bilateral Wilms' tumor were presented to the Children's Hospital Medical Center and Children's Cancer Research Foundation, Sidney Farber Cancer Institute, and Joint Center for Radiation Therapy (CHMC-CCRF, SFCI, JCRT) from January 1, 1956 to December 31, 1976. Of these 20, 16 had simultaneous and 4 had metachronous disease on presentation. All patients were treated with surgery, radiation and chemotherapy. Of the 16 patients with simultaneous disease, 10 (63%) are alive and free of disease 12+ to 175+ months post diagnosis and treatment, with median follow-up of 121 months. There were no long-term survivors in the metachronous group; all were dead of disease within 21 months from initial presentation of original tumor. With these data we relate prognosis to extent of disease and discuss a general approach to the management of bilateral Wilms' tumor

    ABSTRACT Supernumerary tooth is a developmental anomaly and has been argued to arise from multiple etiologies. These teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. They can cause a variety of complications in the develo­ping dentition. Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anterior maxilla. Here is the presentation of a case of unusual location of supernumerary teeth located in between mandibular first and second molar region bilaterally.

    OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors...... are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012...... that a separated hematoma density and the absence of postoperative drainage were independent predictors of retreatment. CONCLUSIONS In bCSDHs bilateral surgical intervention significantly lowers the risk of retreatment compared with unilateral intervention and should be considered when choosing a surgical...

METHODS: We identified all patients diagnosed with tonsillar squamous cell carcinoma (TSCC) in eastern Denmark during a 15-year period to detect the incidence of synchronous BiTSCCs. The tumours were assessed for p16Ink4a expression, the presence of HPV DNA and HPV genotypes....... Furthermore, we systematically reviewed the literature examining BiTSCCs. RESULTS: Of the total of 1119 TSCCs diagnosed in eastern Denmark from 2000 to 2014, we identified 12 BiTSCCs, nine of which initially presented as a cancer of unknown primary (CUP) in the neck. Nine cases were bilaterally HPV16 positive...... (HPV16+), while two cases were HPV16+ in one tonsil and respectively, HPV33 and HPV35 positive in the contralateral tonsil. One case was bilaterally HPV-negative. We also identified an increase in the incidence of BiTSCCs after 2012 when histological examination of the entire tonsil tissue became...

    A 61-year-old woman with metastatic breast cancer presented with migrainelike episodes over the past 10 months. FDG-PET/CT(PET/CT) showed relatively symmetric areas of photopenia predominantly in the bilateral superior parietal lobules. Subsequent contrast-enhanced MRI revealed leptomeningeal metastasis in the bilateral posterior parietal regions with associated vasogenic edema in the adjacent brain parenchyma. There was no clear evidence of parenchymal metastasis on MRI. After chemotherapy, the areas of abnormality resolved on PET/CT 8 months later, and the patient showed interval symptomatic improvement. The present case demonstrates brain parenchymal photopenia on PET/CT as an indirect sign of leptomeningeal metastasis reflecting regional vasogenic edema.

    Pulmonary edema increasingly is recognized as a perioperative complication affecting outcome. Several risk factors have been identified, including those of cardiogenic origin, such as heart failure or excessive fluid administration, and those related to increased pulmonary capillary permeability secondary to inflammatory mediators. Effective treatment requires prompt diagnosis and early intervention. Consequently, over the past 2 centuries a concentrated effort to develop clinical tools to rapidly diagnose pulmonary edema and track response to treatment has occurred. The ideal properties of such a tool would include high sensitivity and specificity, easy availability, and the ability to diagnose early accumulation of lung water before the development of the full clinical presentation. In addition, clinicians highly value the ability to precisely quantify extravascular lung water accumulation and differentiate hydrostatic from high permeability etiologies of pulmonary edema. In this review, advances in understanding the physiology of extravascular lung water accumulation in health and in disease and the various mechanisms that protect against the development of pulmonary edema under physiologic conditions are discussed. In addition, the various bedside modalities available to diagnose early accumulation of extravascular lung water and pulmonary edema, including chest auscultation, chest roentgenography, lung ultrasonography, and transpulmonary thermodilution, are examined. Furthermore, advantages and limitations of these methods for the operating room and intensive care unit that are critical for proper modality selection in each individual case are explored.

    Cerebral edema formation stems from disruption of blood brain barrier (BBB) integrity and occurs after injury to the CNS. Due to the restrictive skull, relatively small increases in brain volume can translate into impaired tissue perfusion and brain herniation. In excess, cerebral edema can be gravely harmful. Astrocytes are key participants in cerebral edema by virtue of their relationship with the cerebral vasculature, their unique compliment of solute and water transport proteins, and their general role in brain volume homeostasis. Following the discovery of aquaporins, passive conduits of water flow, aquaporin 4 (AQP4) was identified as the predominant astrocyte water channel. Normally, AQP4 is highly enriched at perivascular endfeet, the outermost layer of the BBB, whereas after injury, AQP4 expression disseminates to the entire astrocytic plasmalemma, a phenomenon termed dysregulation. Arguably, the most important role of AQP4 is to rapidly neutralize osmotic gradients generated by ionic transporters. In pathological conditions, AQP4 is believed to be intimately involved in the formation and clearance of cerebral edema. In this review, we discuss aquaporin function and localization in the BBB during health and injury, and we examine post-injury ionic events that modulate AQP4- dependent edema formation.

  9. Corticosteroid Treatment in Diabetic Macular Edema

    2017-06-01

    Full Text Available Diabetic macular edema is the most common cause of visual impairment in patients with diabetes mellitus. The pathogenesis of macular edema is complex and multifactorial. For many years, laser photocoagulation has been considered the standard therapy for the treatment of diabetic macular edema; however, few patients achieve significant improvements in visual acuity. Today the intravitreal administration of anti-inflammatory or anti-angiogenic agents together with the use of laser photocoagulation represents the standard of care for the treatment of this complication. The intravitreal route of administration minimizes the systemic side effects of corticosteroids. Steroid-related ocular side effects are elevated intraocular pressure and cataract, while injection-related complications include endophthalmitis, vitreous hemorrhage, and retinal detachment. In order to reduce the risks and complications, intravitreal implants have been developed recently to provide sustained release of corticosteroids and reduce repeated injections for the management of diabetic macular edema. In this review, the efficacy, safety, and therapeutic potential of intravitreal corticosteroids in diabetic macular edema are discussed with a review of recent literature.

    Multiple endocrine neoplasia (MEN) type 2B is a rare hereditary disorder characterized by medullary thyroid carcinoma, pheochromocytoma, and neuroma. Early signs of MEN 2B are usually neuroma, gastrointestinal problems, and medullary thyroid carcinoma. Noncardiogenic pulmonary edema is rare as a presenting symptom. We report a 31-year-old male who was admitted to our hospital because of noncardiogenic pulmonary edema. He was 168 cm in height, weighed 55 kg, and had an arm span of 166 cm. No marfanoid habitus was evident, but thickened lips and tongue neuroma were present. Chronic constipation had been present since childhood, and the patient had a two-year history of untreated hypertension. Noncardiogenic pulmonary edema and toxic megacolon were noted, and abdominal computed tomography revealed bilateral adrenal tumors. Ultrasonography of the thyroid showed two mass lesions. Intubation and mechanical ventilation were performed because of severe hypoxemia. Endocrinological examinations showed high levels of serum and urinary fractionated catecholamines, serum calcitonin, serum carcinoembryonic antigen, and serum intact parathyroid hormone. It was suggested that the high level of catecholamine from pheochromocytoma had caused the pulmonary edema. RET gene analysis showed a codon 918 mutation in exon 16 resulting in an ATG (methionine) to ACG (threonine) substitution, but analysis of the patient's parents showed the wild type. Therefore, the patient was diagnosed as having de novo MEN 2B. He underwent laparoscopic bilateral adrenectomy and total thyroidectomy. However, the values of serum calcitonin and CEA did not decrease to the normal ranges. Patients with early-stage MEN 2B have distinct characteristics that can aid early detection of the disease, thus possibly allowing them to be saved.

    Lupus vulgaris is a common form of cutaneous tuberculosis in China, mostly involving the head and neck region. Turkey ear is a clinically descriptive term, used for a massively enlarged earlobe with bluish-red or violaceous indurated plaques and nodules, which can be a sign of lupus vulgaris. A 47-year-old female presented with edema and reddish ulcerated lesions on both ears which was diagnosed as lupus vulgaris by conventional laboratory investigations and the patient showed good response to antituberculous therapy. Occurrence of turkey ears in lupus pernio (sarcoidosis) should also be mentioned here as this presentation was originally described in this condition. Two case reports of turkey ear have been reported with cutaneous tuberculosis (not bilateral). However, occurrence of bilateral turkey ears in cutaneous tuberculosis has not been described so far in the literature.

    Symptomatic peri-lead edema is a rare complication of deep brain stimulation that has been reported to develop 4 to 120 days postoperatively. Here we report the case of a 63-year-old Hispanic man with an 8-year history of Parkinson's disease who underwent bilateral placement of subthalamic nucleus deep brain stimulation leads and presented with acute, symptomatic, unilateral, peri-lead edema just 33 hours after surgery. We document a thorough radiographic time course showing the evolution of these peri-lead changes and their regression with steroid therapy, and discuss the therapeutic implications of these findings. We propose that the unilateral peri-lead edema after bilateral deep brain stimulation is the result of severe microtrauma with blood-brain barrier disruption. Knowledge of such early manifestation of peri-lead edema after deep brain stimulation is critical for ruling out stroke and infection and preventing unnecessary diagnostic testing or hardware removal in this rare patient population.

    Anthrax is a highly lethal disease caused by the Gram-(+) bacteria Bacillus anthracis. Edema toxin (ET) is a major contributor to the pathogenesis of disease in humans exposed to B. anthracis. ET is a bipartite toxin composed of two proteins secreted by the vegetative bacteria, edema factor (EF) and protective antigen (PA). Our work towards identifying a small molecule inhibitor of anthrax edema factor is the subject of this letter. First we demonstrate that the small molecule probe 5'-Fluorosulfonylbenzoyl 5'-adenosine (FSBA) reacts irreversibly with EF and blocks enzymatic activity. We then show that the adenosine portion of FSBA can be replaced to provide more drug-like molecules which are up to 1000-fold more potent against EF relative to FSBA, display low cross reactivity when tested against a panel of kinases, and are nanomolar inhibitors of EF in a cell-based assay of cAMP production.

    2011-09-01

    Although rarely encountered in the clinical setting, massive tongue edema is a known phenomenon that can occur in craniosynostotic children in the postoperative period. In 1998, Kunhert described an encounter with an adolescent patient with Crouzon syndrome who required craniectomy for complications associated with Chairi malformation [1]. Following her procedure she had rapid tongue edema which was felt to be secondary to obstruction of the venous drainage of the tongue. Despite extensive workup and unsuccessful medical attempts to reduce the swelling, she was extubated with rapid resolution of the tongue edema [1]. In our facility, two children with underlying craniofacial diagnoses underwent elective surgical procedures. During their postoperative course, they encountered postoperative massive tongue swelling which ultimately required tracheotomy to relieve the compression and upper airway obstruction. We describe the clinical manifestations, treatment, and postoperative outcomes identified in these two cases. Published by Elsevier Ireland Ltd.

    Full Text Available Introduction Triazolam belongs to the group of benzodiazepines and may have side effects on the respiratory system which include not only respiratory depression, but also transient benign non cardiac pulmonary edema.Case report A 52 year old obese woman developed pulmonary edema after she was taking triazolam for almost two weeks without any other medications. All possible cardiogenic and non cardiogenic causes were excluded. The condition was severe enough to require non invasive ventilation.Discussion This case differs from the other report of triazolam associated non cardiac pulmonary edema for its severity requiring non invasive ventilation. The pathogenetic mechanism is unknown. Despite the lack of objective evidence to explain pulmonary venous hypertensive changes in our case, we want to advice that triazolam should be used with caution in obese patients, as obesity might aggravate this described drug adverse reaction.

    Full Text Available El edema cerebral es una complicación clínica severa, asociada a numerosas patologías y es causa frecuente de muerte. Puede ser vasogénico o celular, aunque generalmente ambos tipos de edema coexisten. El edema celular afecta de manera predominante a los astrocitos y ocurre en condiciones hiposmóticas (hiponatremia o isosmóticas (traumatismo craneoencefálico, isquemia, epilepsias, encefalopatía hepática. En el edema hiposmótico las células del cerebro tienen la capacidad de recuperar el volumen, mediante un mecanismo activo de adaptación, consistente en la movilización de osmolitos intracelulares, que son los iones K+ y Cl- y moléculas orgánicas, como aminoácidos, polialcoholes y aminas. La adaptación a la condición de hiponatremia modifica la concentración de estos osmolitos, restableciendo la isosmolaridad de la célula con el entorno hiposmótico. La corrección de la condición hiponatrémica debe tomar en cuenta estos mecanismos adaptativos para evitar que un ajuste demasiado rápido no sea seguido por el correspondiente cambio en la concentración de osmolitos intracelulares. En el edema isosmótico, aparentemente no existen los mecanismos de regulación activa del volumen debido, posiblemente a que es el cambio en la distribución iónica el responsable del edema. Por ello, la estrategia de prevención parece ser el mecanismo indicado para evitar las complicaciones asociadas a este tipo de edema.

    Full Text Available It is generally agreed that the testis is under endocrine control from the pituitary, and is influenced by physiological and paracrine factors within the organ.The aim of this study is to analyze the effect of unilateral and bilateral epididectomy on the testicular tissue growth of rats.Twenty- one male old Sprague-Dawley rats (28 days old were used in the study. Rats were assigned into 3 equal groups. The first group was the control group, while unilateral and bilateral epididectomy was performed on the second and third groups, respectively. Twenty-one days after the epididectomy, testicular tissues from each group were taken and fixed in Bouin solution. Paraffin sections were stained with Haematoxylin and Eosin, Vangiesson, PAS-Hemalun and examined by light microscopy.Disorganization of the germinal epithelium, desquamation, degeneration and edema in interstitial tissue was seen in the testicular cross sections of the unilateral group. Arrest in spermatozoon stage in some tubules and presence of eosinophylic stained multinucler bodies were recognizable. In the bilateral group, degeneration and atrophic status in the seminiferous tubules of the bilateral group was observed preciesly, and occasional interstitial edema and perforations in the basal lamina were recognizable. In addition, vasodilatation, arrest in spermatozoa stage and multinucleated bodies in some of the seminiferous tubules lumen were observed in some testicular cross sections of this group.As a result, epididectomy causes degeneration in the germinal epithelium and hypoplasia in Leydig cells.It is concluded that epididectomy causes degeneration in the germinal epithelium, interruption of spermatogenesis, and a notable decrease in the number of Leydig cells.

    1991-01-01

    Perfusion scintigraphy of the lungs has shown that a reverse direction of postural reactions of the pulmonary blood flow is observed in patients with mitral valvular disease. It is accounted for by the action of gravitation on capillary hydrostatic pressure resulting in the localization of interstitial edema in pulmonary venous hypertension mainly in the lower lung, its microcirculatory bed being compressed and the blood flow redistributed to the opposite upper lung. Therefore successive perfusion scintigraphy of the lungs in the vertical position and in the lateral position with a RP administered twice, can serve as a sensitive test for diagnosis of interstitial lung edema

    Full Text Available Radiation retinopathy (RR is a progressive, chronic condition directly related to the amount of radiation administered to the retina. We report a 37-year-old patient with medulloblastoma that was treated with external beam radiation and presented to us with bilateral cystoid macular edema. He was treated with monthly bevacizumab injections only in his worst seeing eye. There was a significant improvement in his fellow eye, with marked retinal thickness reduction. Therefore, we present clinical evidence of systemic absorption and fellow eye activity of the drug (bevacizumab. One must be aware of distant side effects after intravitreal injections.

    Carbon monoxide (CO) intoxication is a leading cause of severe neuropsychological impairments. Peripheral nerve injury has rarely been reported. It consists usually in a demyelinating polyneuropathy or mononeuropathy affecting mainly the lower limbs. Isolated involvement of both upper extremities has been described in only 4 patients related to root damage. We report the first case of bilateral brachial plexus injury following CO poisoning and review all previous CO-induced neuropathy described in literature. After being unconscious for three hours, a 42 years old man experienced bilateral brachial weakness associated with edema of the face and the upper limbs. Neurological examination showed a brachial diplegia, distal vibratory, thermic and algic hypoesthesia, deep tendon areflexia in upper limbs. There was no sensory or motor deficit in lower extremities. No cognitive disturbances were detected. Creatine kinase was elevated. Electroneuromyogram patterns were compatible with the diagnosis of bilateral C5 D1 brachial axonal plexus injury predominant on the left side. Clinical course after hyperbaric oxygen therapy was marked by a complete recovery of neurological disorders. Peripheral neuropathy is an unusual complication of CO intoxication. Bilateral brachial plexus impairment is exceptional. Various mechanisms have been implicated including nerve compression secondary to rhabdomyolysis, nerve ischemia due to hypoxia and direct nerve toxicity of carbon monoxide. Prognosis is commonly excellent without any sequelae.

    Bilateral high signal intensity in basal ganglia on T1-weighted images is unusual, the purpose of this study is to describe the pattern of high signal intensity and underlying disease. During the last three years, 8 patients showed bilateral high signal intensity in basal ganglia on T1-weighted image, as compared with cerebral white matter. Authors analyzed the images and underlying causes retrospectively. Of 8 patients, 5 were male and 3 were female. The age ranged from 15 days to 79 years. All patient were examined by a 0.5T superconductive MRI. Images were obtained by spin echo multislice technique. Underlying causes were 4 cases of hepatopathy, 2 cases of calcium metabolism disorder, and one case each of neurofibromatosis and hypoxic brain injury. These process were bilateral in all cases and usually symmetric. In all cases the hyperintense areas were generally homogenous without mass effect or edema, although somewhat nodular appearance was seen in neurofibromatosis. Lesions were located in the globus pallidus and internal capsule in hepatopathy and neurofibromatosis, head of the caudate nucleus in disorder of calcum metabolism, and the globus pallidus in hypoxic brain injury. Although this study is limited by its patient population, bilateral hyperintense basal ganglia is associated with various disease entities. On analysis of hyperintense basal ganglia lesion, the knowledge of clinical information improved diagnostic accuracy

    2013-01-01

    Full Text Available The main objective of the facial edema evaluation is providing the needed information to determine the effectiveness of the anti-inflammatory drugs in development. This paper presents a system that measures the four main variables present in facial edemas: trismus, blush (coloration, temperature, and inflammation. Measurements are obtained by using image processing and the combination of different devices such as a projector, a PC, a digital camera, a thermographic camera, and a cephalostat. Data analysis and processing are performed using MATLAB. Facial inflammation is measured by comparing three-dimensional reconstructions of inflammatory variations using the fringe projection technique. Trismus is measured by converting pixels to centimeters in a digitally obtained image of an open mouth. Blushing changes are measured by obtaining and comparing the RGB histograms from facial edema images at different times. Finally, temperature changes are measured using a thermographic camera. Some tests using controlled measurements of every variable are presented in this paper. The results allow evaluating the measurement system before its use in a real test, using the pain model approved by the US Food and Drug Administration (FDA, which consists in extracting the third molar to generate the facial edema.

    MR imaging criteria for diagnosing acute disseminated encephalomyelitis (ADEM) have not been clearly established. Due to the wide spectrum of differential considerations, new imaging features allowing early and accurate diagnosis for ADEM are needed. We hypothesized that ADEM lesions would be characterized by vasogenic edema due to the potential reversibility of the disease. Sixteen patients who met the diagnostic criteria for ADEM proposed by the International Pediatric Multiple Sclerosis Study Group (IPMSSG) and had complete MR imaging studies performed at our institution during the acute phase of the disease were identified retrospectively and evaluated by experienced pediatric neuroradiologists. Vasogenic edema was demonstrated on diffusion-weighted imaging (DWI) and corresponding apparent diffusion coefficient (ADC) maps in 12 out of 16 patients; cytotoxic edema was identified in two patients while the other two patients displayed no changes on DWI/ADC. ADC values for lesions and normal-appearing brain tissue were 1.39 ± 0.45 x 10{sup -3} and 0.81 ± 0.09 x 10{sup -3} mm/s{sup 2}, respectively (p = 0.002). When considering a cutoff of 5 days between acute and subacute disease, no difference between ADC values in acute vs. subacute phase was depicted. However, we found a significant correlation and an inverse and significant relationship between time and ADC value. We propose that vasogenic edema is a reliable diagnostic sign of acute neuroinflammation in ADEM. (orig.)

    2001-04-01

    We diagnosed and treated a case of Ludwig's angina in a 45-year-old man who had edema of the floor of mouth and the tongue along with bilateral submandibular sialadenitis and sialolithiasis. We secured the patient's airway via nasal fiberoptic intubation in the surgical intensive care unit and administered intravenous antibiotics. The edema subsided, and the patient was extubated on the third postoperative day and discharged shortly thereafter. To our knowledge, this is the first reported case of a patient with bilateral submandibular sialadenitis and sialolithiasis presenting as Ludwig's angina. Despite the decreasing incidence of this disease, Ludwig's angina remains an important disease process because a failure to control the airway can have disastrous consequences. Proper diagnosis, airway control, antibiotic therapy, and occasionally surgical management are essential to ensure the safety of the patient.

    2005-06-01

    Bilateral internal carotid artery dissections have been reported, but spontaneous bilateral dissections are rare. Internal carotid artery dissection can present with a spectrum of symptoms ranging from headache to completed stroke. Two cases of spontaneous bilateral carotid artery dissection are presented, one with headache and minimal symptoms and the other with a stroke syndrome. No cause could be found in either case, making the dissections completely spontaneous. Bilateral internal carotid artery dissection (ICAD) should be considered in young patients with unexplained head and neck pain with or without focal neurological symptoms and signs. The increasing availability of imaging would sustain the higher index of suspicion.

A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    Full Text Available Purpose. To characterize the economic and quality of life burden of diabetic macular edema (DME in Canadian patients. Patients and Methods. 145 patients with DME were followed for 6 months with monthly telephone interviews and medical chart reviews at months 0, 3, and 6. Visual acuity in the worst-seeing eye was assessed at months 0 and 6. DME-related healthcare costs were determined over 6 months, and vision-related (National Eye Institute Visual Functioning Questionnaire and generic (EQ-5D quality of life was assessed at months 0, 3, and 6. Results. Mean age of patients was 63.7 years: 52% were male and 72% had bilateral DME. At baseline, visual acuity was categorized as normal/mild loss for 63.4% of patients, moderate loss for 10.4%, and severe loss/nearly blind for 26.2%. Mean 6-month DME-related costs/patient were as follows: all patients (n=135, $2,092; normal/mild loss (n=88, $1,776; moderate loss (n=13, $1,845; and severe loss/nearly blind (n=34, $3,007. Composite scores for vision-related quality of life declined with increasing visual acuity loss; generic quality of life scores were highest for moderate loss and lowest for severe loss/nearly blind. Conclusions. DME-related costs in the Canadian healthcare system are substantial. Costs increased and vision-related quality of life declined with increasing visual acuity severity.

    Full Text Available Purpose: To report the impact of transient, self-resolving, untreated "macular edema" detected on spectral domain optical coherence tomography in Asian Indian premature infants with retinopathy of prematurity (ROP on visual acuity (VA and refraction at 1-year of corrected age. Materials and Methods: Visual acuity and refraction of 11 infants with bilateral macular edema (Group A was compared with gestational age-matched 16 infants with ROP without edema (Group B and 17 preterms infants without ROP and without edema (Group C at 3, 6, 9 and 12 months of corrected age using Teller Acuity Cards and cycloplegic retinoscopy. Sub-group analysis of the previously described pattern A and B macular edema was performed. Results: Visual acuity was lower in infants with macular edema compared with the other two control groups throughout the study period, but statistically significant only at 3 months. Visual improvement in these infants was highest between the 3 rd and 6 th month and plateaued by the end of the 1 st year with acuity comparable to the other two groups. The edema cohort was more hyperopic compared to the other two groups between 3 and 12 months of age. Pattern A edema had worse VA compared to pattern B, although not statistically significant. Conclusion: Macular edema, although transient, caused reduced VA as early as 3 months of corrected age in Asian Indian premature infants weighing <2000 g at birth. The higher hyperopia in these infants is possibly due to visual disturbances caused at a critical time of fovealization. We hypothesize a recovery and feedback mechanism based on the principles of active emmetropization to explain our findings.

    Full Text Available O edema pulmonar neurogênico é rara e grave complicação de pacientes com traumatismo craniencefálico (TCE. Pode ocorrer também em outras patologias do sistema nervoso central, tais como acidentes vasculares cerebrais (AVC, tumores ou após crises epilépticas, entre outras. Foram avaliados 36 casos com TCE grave e quatro pacientes com AVC, internados na UTI geral, no período de janeiro a setembro 1995. Nesse intervalo de tempo foram diagnosticados dois casos de edema pulmonar neurogênico, um ocorrendo em paciente com TCE grave e outro em paciente com AVC hemorrágico. O diagnóstico foi estabelecido pelo rápido desenvolvimento de edema pulmonar, com hipoxemia grave, queda da complacência pulmonar e infiltrados difusos bilaterais sem história prévia de aspiração traqueal ou outro fator de risco para o desenvolvimento de síndrome de angústia respiratória aguda. No primeiro paciente com trauma craniencefálico, o edema neurogênico foi diagnosticado na internação, uma hora após o trauma, com concomitante reação inflamatória grave e boa evolução em três dias. O outro caso, com AVC hemorrágico, desenvolveu edema neurogênico no quarto dia após drenagem de hematoma intraparenquimatoso, evoluindo para o óbito.Neurogenic pulmonary edema is a rare and serious complication in patients with head injury. It also may develop after a variety of cerebral insults such as subarachnoid hemorrhage, brain tumors and after epileptic seizures. Thirty six patients with severe head injury and four patients with cerebrovascular insults treated in Intensive Care Unit of HC-UNICAMP from January to September 1995 were evaluated. In this period there were two patients with neurogenic pulmonary edema, one with head injury and other with intracerebral hemorrhage. Diagnosis was made by rapid onset of pulmonary edema, severe hypoxemia, decrease of pulmonary complacence and diffuse pulmonary infiltrations, without previous history of tracheal

    Clinical and neuroradiological studies involving cerebral angiography were conducted in four patients with eclampsia. In three cases (case 1, 2 and 4), neurological focal signs, abnormal low density areas on cranial CT and T{sub 2} high intensity areas on cranial MRI disappeared within a month. But in one case (case 3), cerebral infarction occurred and right hemiparesis and aphasia persisted. Cerebral angiography in the acute phase demonstrated vasospasm in all cases and arterial occlusion in the middle cerebral artery due to vasospasm in case 3. Angiography demonstrated several types of spasms, including diffuse, peripheral and multi local. Furthermore, in some cases, diffuse vasospasms were recognized at the siphon and extracranial portions of the internal carotid artery. In one case (Case 4), segmental vasospasms were detected in the bilateral vertebral arteries. Three to four weeks later, follow-up cerebral angiography was performed in three cases. Cerebral vasospasms had partially or completely recovered. Subarachnoid hemorrhage (SAH) was excluded by lumbar puncture and neuroradiological findings in all cases. We concluded that eclampsia itself causes cerebral vasospasm and that the mechanism of vasospasm is different from that of SAH, since cerebral vasospasm occurred in the extracranial cerebral arteries. We suspected that cerebral vasospasm in eclampsia causes cerebral ischemia, which leads to cytotoxic edema and dysfunction of the blood-brain barrier (BBB) and cerebral autoregulation. With this background, brain edema, especially vasogenic edema, may easily occur and clinical symptoms of eclampsia may appear when the blood pressure rapidly increases. (author).

    Full Text Available Diabetic macular edema (DME is a major cause of visual impairment in diabetic patients. Laser photocoagulation is the standard management strategy for macular edema, but its results remain unsatisfactory. Several clinical trials of new treatment modalities for DME have been conducted over the past 10 years. We performed a literature search of English articles, published between 2000 and 2010, by using the PubMed database. The keywords searched included “diabetic macular edema and treatment” with limits set to include only clinical trials and review articles, over 50 articles were reviewed. Among the newer treatment modalities reviewed, therapy with anti-vascular endothelial growth factor (VEGF antibodies showed significantly better efficacy, with level I evidence. However, multiple injections were required to maintain its efficacy. Therefore, the associated complications and cost implications are the major limitations of this treatment. Several combinations of different modalities have been evaluated in the literature, but none are more efficacious than monotherapy with anti-VEGF antibodies. Since DME is a multifactorial disease, further studies involving combinations of modalities or new treatments modalities may be needed to reduce the number of injections required or improve the visual outcomes in case of DME.

    Pulmonary edema has been revealed in 132 patients (51.6 %) during radiologic examination of 256 patients with chronic renal failure. The performance of anterio-posterior chest radiographs was in most cases necessary and quite sufficient for making diagnostic conclusions. Follow up study of patients with pulmonary edema and analysis of radiologic picture of the alterations permitted physicians to distinguish approximately 3 stages of the process development, which transit from one into another. Stage 1 involves early disorders and prodromes of pulmonary edema; Stage 2 interstitial lung edema; Stage 3 alveolar edema. The circulation enforcement of the upper lobar vessels has been the main feature of stage 1. Radiogramometry provided additional information for the pulmonary edema diagnosis. For instance, cardioradiometric data are useful for pulmonary edema diagnosis and evidence in favour of its close connection with heart disorders

    Full Text Available Escitalopram is an antidepressant of the selective serotonin reuptake inhibitor(SSRI class. In this manuscript, we report the case of a female patient who developed bilateral acute angle-closure glaucoma induced by escitalopram. A 46-year-old female patient was admitted to our ophthalmology clinic with complaints of severe pain around the both eyes, headache, nausea, and vomiting for two days. In her past medical history, she was using escitalopram for depression for two years. Visual acuity was at hand movement level in both eyes. Anterior segment examination showed bilateral diffuse conjunctival hyperemia, corneal edema, shallow anterior chamber, and fixed dilated pupils. Intraocular pressure was 47 mmHg in the right and 68 mmHg in the left eye. The diagnosis was acute angle-closure glaucoma, and the escitalopram medication was discontinued. She was treated with topical and systemic antiglaucomatous medication. After the cornea become clear, bilateral peripheral laser iridotomy was done. In the following year, she did not begin escitalopram medication again and no other acute angle-closure attack was seen. (Turk J Ophthalmol 2014; 44:396-9

    Pathophysiological changes in experimental brain edema and cerebral ischemia were examined by the in vivo 1 H- and 31 P-NMR method. Two types of experimental brain edema were induced in rats by cold injury and by triethyltin (TET) intoxication. Experimental cerebral ischemia was induced in rats by the four-vessel occlusion method. During the course of these pathological conditions, the 1 H-MRIs and 31 P-NMR spectra were measured sequentially with a single NMR spectrometer (4.8 tesla, 9 cm bore magnet). In the cold-injury edema, high-intensity lesions were detected in the gray and white matters of the injured hemisphere by means of SE images with a long Te 3 hours after the injury. The intensity reached its maximum 16 to 24 hours after the injury, and then returned to normal 7 days later. These high-intensity lesions indicated an increase in the T2 value in the edematous tissue. There were no changes in the 31 P-NMR spectra during the course of edema formation and absorption. In the TET-induced edema, high-intensity lesions were also detected in the bilateral white matter by means of SE images with a long Te from the 3rd day up to the 7th day during the injection of TET. These high-intensity lesions subsided 42 days after the discontinuance of injecting TET. There were no changes in the 31 P-NMR spectra during the whole course of TET-induced edema. In the cerebral ischemia, no remarkable changes in the MRI were detected in either SE or IR images during the ischemic and recirculated periods. However, dynamic changes in the 31 P-NMR spectra were detected during the course of cerebral ischemia. In the pre-ischemic period, the peaks of the ATP, PCr, phosphodiesters (PDE), Pi, and phosphomonoesters (PME) were detected. After the induction of ischemia, the ATP and PCr peaks decreased, while one Pi peak increased rapidly. (J.P.N.)

    Full Text Available We tested the capacity of leaf (Urera baccifera, Loasa speciosa, Urtica leptuphylla, Chaptalia nutans, and Satureja viminea and root (Uncaria tomentosa extracts to inhibit edema induced by Bothrops asper snake venom. Edema-forming activity was studied plethysmographically in the rat hind paw model. Groups of rats were injected intraperitoneally with various doses of each extract and, one hour later, venom was injected subcutaneously in the right hind paw. Edema was assessed at various time intervals. The edematogenic activity was inhibited in those animals that received an injection U. tomentosa, C. nutans or L. speciosa extract. The extract of U. baccifera showed a slight inhibition of the venom effect. Extract from S. viminea and, to a lesser extent that of U. leptuphylla, induced a pro-inflammatory effect, increasing the edema at doses of 250 mg/kg at one and two hours. Rev. Biol. Trop. 54(2: 245-252. Epub 2006 Jun 01.Se investigó la capacidad de los extractos de las hojas de Urera baccifera, Loasa speciosa, Urtica leptuphylla, Chaptalia nutans, Satureja viminea y de la raíz de Uncaria tomentosa para inhibir el edema inducido por el veneno de Bothrops asper por métodos pletismométricos. Los grupos de ratas fueron inyectados intraperitonealmente con varias dosis de cada extracto y una hora mas tarde se inyectó veneno por vía subcutánea en la pata trasera derecha de la rata. Se evaluó el edema en distintos intervalos de tiempo. Los resultados muestran que la actividad edematogénica fue inhibida en los animales que recibieron los extractos de raíz de U. tomentosa, hojas de C. nutans y L. speciosa. Los extractos de hojas de U. baccifera mostraron leve inhibición del efecto del veneno. El extracto de hojas de S. viminea y en menor grado el de U. leptuphylla indujeron un efecto pro inflamatorio.

    Full Text Available Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

    Full Text Available We present a case of a metastatic breast cancer patient with cystoid macular edema (CME occurring during treatment with paclitaxel and bevacizumab. She had a history of neoadjuvant chemotherapy and partial mastectomy plus axillary lymph node dissection for stage IIB left-breast cancer. Twenty-four months later, she was diagnosed with multiple bone metastases and underwent chemotherapy with paclitaxel and bevacizumab. Thirty-three months after the initiation of the chemotherapy, she noticed bilateral blurred vision. The retinal thickening with macular edema was observed by optical coherence tomography, resulting in a diagnosis of CME. With cessation of paclitaxel and administrating ocular instillation of a nonsteroidal anti-inflammatory drug, her macular edema gradually reduced and disappeared in a month. While CME caused by chemotherapy is very rare, taxane may cause ocular adverse events such as CME. It is important to urge patients to consult an ophthalmologist promptly when they have visual complaints during taxane chemotherapy.

    Early diagnosis of breast vasculitis (BV) is difficult because this condition is rare and occasionally mimics breast cancer clinically or radiologically. It may present as systemic disease or as an isolated lesion in the breast, without systemic evidence. When vasculitis appears in the breast, it also might manifest as a tumor-like lesion, and in previous cases, tissue acquisition was needed for confirmation of the diagnosis because of BV's resemblance to inflammatory breast cancer. We report a case of isolated BV that was suspected of being inflammatory breast cancer clinically, but manifested as bilateral breast edema on mammography. In this case, sonographic findings included not only nonspecific edema findings that might be seen in other cases, but also suggestive findings of hypoechoic circumferential arterial wall thickening with perivascular fat infiltrations that are similar to the halo sign in large arteries but have not been reported in the breast. These are helpful for presumptive diagnosis of BV using ultrasound.

    Dialysis disequilibrium syndrome is a metabolic complication that can be caused by rapid removal of plasma urea during hemodialysis. Dialysis disequilibrium syndrome can lead to osmotic demyelinating syndrome. This case report describes one case of encephalopathy accompanied by dialysis disequilibrium syndrome with imaging findings acquired immediately after hemodialysis in a 55-year-old woman with chronic renal failure. The patient was observed to present repetitive seizures and sudden deterioration of consciousness immediately after hemodialysis. Shortly after the onset of symptoms, the patient underwent a CT scan. The imaging findings of the CT scan reveal symmetrical diffuse white matter edema of bilateral cerebral hemispheres that extends to the pons along the internal capsule. A follow-up MRI taken two years later shows that reversible changes without damage have occurred in the lesions. The patient can thus be seen to present symptoms characteristically associated with dialysis disequilibrium syndrome, while brain imaging reveals dif-fuse reversible brain edema.

    Fingolimod is a potent drug in relapsing forms of multiple sclerosis. Visual impairment due to fingolimod-associated macular edema (FAME) usually leads to discontinuation of fingolimod therapy. We report on a 24-year old woman with bilateral FAME. We continued fingolimod and added oral acetazolamide, which led to recovery of visual acuity and regression of macular edema. However, fingolimod had to be discontinued when fluorescein angiography revealed an enlarged foveal avascular zone. Oral acetazolamide might be a treatment option for FAME, while ischemic conversion may be limiting. Ophthalmologic assessments are mandatory for follow-up when fingolimod therapy is continued after onset of FAME. Copyright © 2015 Elsevier B.V. All rights reserved.

  7. Dialysis Disequilibrium Syndrome-Induced Cerebral Edema in a Patient with Uremia Following Hemodialysis: A Case Report

    2012-01-01

    Dialysis disequilibrium syndrome is a metabolic complication that can be caused by rapid removal of plasma urea during hemodialysis. Dialysis disequilibrium syndrome can lead to osmotic demyelinating syndrome. This case report describes one case of encephalopathy accompanied by dialysis disequilibrium syndrome with imaging findings acquired immediately after hemodialysis in a 55-year-old woman with chronic renal failure. The patient was observed to present repetitive seizures and sudden deterioration of consciousness immediately after hemodialysis. Shortly after the onset of symptoms, the patient underwent a CT scan. The imaging findings of the CT scan reveal symmetrical diffuse white matter edema of bilateral cerebral hemispheres that extends to the pons along the internal capsule. A follow-up MRI taken two years later shows that reversible changes without damage have occurred in the lesions. The patient can thus be seen to present symptoms characteristically associated with dialysis disequilibrium syndrome, while brain imaging reveals dif-fuse reversible brain edema.

    Pulmonary edema is a potentially life-threatening complication of acute airway obstruction. It develops rapidly, without warning, in young healthy individuals. Two forms of post-obstructive pulmonary edema (POPE) (also known as negative pressure pulmonary edema, NPPE) have been identified. POPE I follows sudden, severe upper airway obstruction. POPE II occurs following surgical relief of chronic upper airway obstruction. Treatment for both is supportive. Full and rapid recovery can be expecte...

    The finding of muscle edema restricted to a single muscle compartment on MRI usually indicates a diagnosis of traumatic injury, myositis, denervation or neoplasm. This case demonstrates that deep venous thrombosis can also be the cause of isolated deep posterior compartment muscle edema in the calf and should be considered in the differential diagnosis even in the absence of diffuse soft tissue or subcutaneous edema.

    Cerebral edema plays a central role in the pathophysiology of many diseases of the central nervous system (CNS) including ischemia, trauma, tumors, inflammation, and metabolic disturbances. The formation of cerebral edema results in an increase in tissue water content and brain swelling which, if unchecked, can lead to elevated intracranial pressure (ICP), reduced cerebral blood flow, and ultimately cerebral herniation and death. Despite the clinical significance of cerebral edema, the mechan...

    The purpose of this study is to evaluate the incidence and the degree of peritumoral edema on MRI in meningioma and to correlate other MR findings with the edema. MR images of 35 patients with histologically confirmed meningioma were retrospectively reviewed. We analyzed the MR findings with special attention to the presence or absence and degree of edema. The edema was grade as absent, mild (extending less than 1 cm from outer margin of mass), moderate (1 to 3 cm with mild mass effect), and severe (more than 3 cm with marked mass effect). We also evaluated size and margin of the tumor, heterogeneity of mass signal, enhancement pattern and dural enhancement of the masses. In 24 patients with cerebral angiography, cerebral vascularity on angiogram was correlated with MR findings. Statistic correlation analysis was done using SAS ver 6.04. Twenty five of 35 cases (72%) had edema; mild in 11 case, moderate in 10 cases, and severe in 4 cases. Heterogeneous signal intensity of mass (<0.001), heterogeneous enhancement of mass (<0.001). mass size (<0.001), location (<0.001), and vascularity on angiography (<0.05) were well correlated with edema, while mass margin (>0.05), dural enhancement (>0.05), and histologic type (>0.05) were not correlated with edema. In meningioma, moderate to severe peritumoral edema occurred in 41% (14/35). The edema was correlated with heterogenous enhancement, size, location, heterogeneous signal intensity and vascularity of the mass on angiography.

    Pulmonary edema is the pathological increase of extravascular lung water found most often in patients with congestive heart failure and other critically ill patients who suffer from intravenous fluid overload. A non-invasive lung density monitor that is accurate, easily portable, safe and inexpensive is needed for clinical evaluation of pulmonary edema. Other researchers who have employed Compton scattering techniques generally used systems of extended size and detectors with poor energy resolution. This has resulted in significant systematic biases from multiply-scattered photons and larger errors in counting statistics at a given radiation dose to the patient. We are proposing a patented approach in which only backscattered photons are measured with a high-resolution HPGe detector in a compact system geometry. By proper design and a unique data extraction scheme, effects of the variable chest wall on lung density measurements are minimized. Preliminary test results indicate that with a radioactive source of under 30 GBq, it should be possible to make an accurate lung density measurement in one minute, with a risk of radiation exposure to the patient a thousand times smaller than that from a typical chest x-ray. The ability to make safe, frequent lung density measurements could be very helpful for monitoring the course of P.E. at the hospital bedside or outpatient clinics, and for evaluating the efficacy of therapy in clinical research. 6 refs., 5 figs.

    Experimental cerebral edema was produced on the right parietal lobe of Wistar male rats with a cold metal probe cooled by liquid nitrogen. Twenty hour later, 3 H-dexamethasone was either intramuscularly or intravenously injected into rats, estimated in the brain tissue by the liquid scintillation counting method. Edematous brain generally contained much higher 3 H-activity than the control. Furthermore, I.V. injection showed higher 3 H-activity than I.M injection in edematous and control brains at all times. For examination of the subcellular distribution of 3 H-dexamethasone in edematous brain, 3 H-activity was most strongly detected in the supernatant fraction (63%), followed by the heavy mitochondrial fraction (25.4%) and the nuclear fraction (8.4%). Although edematous brain tissue constantly demonstrated higher 3 H-activity than the control, its supernatant fraction conversely had less activity. As a next step, distribution of 3 H-dexamethasone in the supernatant fraction was studies. The result was that the high molecular weight fraction in the edematous brain showed higher radioactivity than the control. From these findings, unequivocal distribution of dexamethasone in the supernatant fraction of edematous brain tissue could be correlated with its biochemical action for preventing brain edema.

    Pseudophakic cystoid macular edema (PCME) is a common complication following cataract surgery. Acute PCME may resolve spontaneously, but some patients will develop chronic macular edema that affects vision and is difficult to treat. This disease was described more than 50 years ago, and there are multiple options for clinical management. We discuss mechanisms, clinical efficacy, and adverse effects of these treatment modalities. Topical non-steroidal anti-inflammatory agents and corticosteroids are widely used and, when combined, may have a synergistic effect. Intravitreal corticosteroids and anti-vascular endothelial growth factor (anti-VEGF) agents have shown promise when topical medications either fail or have had limited effects. Randomized clinical studies evaluating anti-VEGF agents are needed to fully evaluate benefits and risks. When PCME is either refractory to medical therapy or is associated with significant vitreous involvement, pars plana vitrectomy has been shown to improve outcomes, though it is associated with additional risks.

    2006-10-01

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    Brain edema in unruptured brain arteriovenous malformations (AVMs) is rare; this study examines (1) its frequency and clinical presentation, (2) imaging findings with emphasis on venous drainage abnormalities, and (3) implications of these findings on natural history and management. Presentation and imaging features of all unruptured brain AVMs were prospectively collected in our brain AVM database. Neurological findings, size, location, venous drainage pattern, presence of venous thrombosis, ectasia, or stenosis, and brain edema were specifically recorded. Treatment details of all patients with brain edema and their clinical and imaging follow-up were reviewed. Finally, a comparison was made between patients with and without edema. Brain edema was found in 13/329 unruptured brain AVMs (3.9%). Neurological deficit (46.2%), venous thrombosis (38.5%), venous ectasia (84.6%), stenosis (38.5%), and contrast stagnation in the draining veins (84.6%) were more frequent in patients with brain edema than without edema. Eight patients with brain edema received specific treatment (embolization = 5, surgery = 2, radiosurgery = 1). Clinical features correlated well with change in degree of edema in six. Three of five embolized patients were stable or showed improvement after the procedure. On follow-up, however, intracranial hemorrhage developed in three. Brain edema in unruptured brain AVMs is rare, 3.9% in this series. Venous outflow abnormalities are frequently associated and appear to contribute to the development of edema. Progressive nonhemorrhagic symptoms are also associated, with a possible increased risk of hemorrhage. Palliative embolization arrests the nonhemorrhagic symptoms in selected patients, although it may not have an effect on hemorrhagic risk. (orig.)

  1. Resolution of Pulmonary Edema. Thirty Years of Progress

    2014-01-01

    In the last 30 years, we have learned much about the molecular, cellular, and physiological mechanisms that regulate the resolution of pulmonary edema in both the normal and the injured lung. Although the physiological mechanisms responsible for the formation of pulmonary edema were identified by 1980, the mechanisms that explain the resolution of pulmonary edema were not well understood at that time. However, in the 1980s several investigators provided novel evidence that the primary mechanism for removal of alveolar edema fluid depended on active ion transport across the alveolar epithelium. Sodium enters through apical channels, primarily the epithelial sodium channel, and is pumped into the lung interstitium by basolaterally located Na/K-ATPase, thus creating a local osmotic gradient to reabsorb the water fraction of the edema fluid from the airspaces of the lungs. The resolution of alveolar edema across the normally tight epithelial barrier can be up-regulated by cyclic adenosine monophosphate (cAMP)-dependent mechanisms through adrenergic or dopamine receptor stimulation, and by several cAMP-independent mechanisms, including glucocorticoids, thyroid hormone, dopamine, and growth factors. Whereas resolution of alveolar edema in cardiogenic pulmonary edema can be rapid, the rate of edema resolution in most patients with acute respiratory distress syndrome (ARDS) is markedly impaired, a finding that correlates with higher mortality. Several mechanisms impair the resolution of alveolar edema in ARDS, including cell injury from unfavorable ventilator strategies or pathogens, hypoxia, cytokines, and oxidative stress. In patients with severe ARDS, alveolar epithelial cell death is a major mechanism that prevents the resolution of lung edema. PMID:24881936

    To investigate the change of brain edema in patients with cerebral infarction by non-invasive cerebral electrical impedance (CEI) measurements. An invariable secure current at a frequency of 50 kHz and an intensity of 0.1 mA was given into a person's brain. CEI values of the bilateral hemisphere of 200 healthy volunteers and 107 patients with cerebral infarction were measured by non-invasive brain edema monitor. The results of perturbative index (PI) converted from CEI were compared with the volumes of brain edema, which were calculated by an image analysing system according to magnetic resonance imaging or computed tomography. (1) In the healthy volunteers, PI values in the left and right hemisphere were 7.98 +/- 0.95 and 8.02 +/- 0.71 respectively, and there was no significant difference between the two sides (p>0.05). Age, gender and different measuring times did not obviously affect PI values (p>0.05). (2) In the cerebral infarction group, CEI measurements were more sensitive to the volumes of lesion, which were more than 20 ml. The positive ratio of PI was higher when the volumes of infarction were >20 ml (80.0%): the ratio of PI was 75.9% when the volumes of infarction were 20-50 ml and it was 83.3% when the volumes of lesion were more than 50 ml. PI was lower when the volumes were less than 20 ml. (3) PI of the infarction side increased obviously 3-5 days after onset; the difference of two sides was the most significant. There was a positive correlation between PI of the infarction side and volume of infarction. PI may be a sensitive parameter for non-invasive monitoring of the change of brain edema in patients with cerebral infarction. CEI is a valuable method for the early detection of brain edema.

    Decompressive surgery has since long been a promising therapeutic approach for patients with acute severe brain injury at risk to develop severe brain edema. The underlying rationale of removing part of the cranium is to create space for the expanding brain to prevent secondary damage to vital brain tissue. However, until recently, randomized controlled trials that demonstrate the efficacy of decompressive surgery or benefit for outcome were missing. This has changed since the results of 3 randomized trials on hemicraniectomy in malignant infarction of the middle cerebral artery have been published in 2007. In this article, the current evidence for decompressive surgery in the treatment of cerebral ischemia, intracranial hemorrhage, traumatic brain injury, inflammatory diseases, or severe metabolic derangements is reviewed. Although there is increasing evidence for the efficacy of decompressive surgery in reducing intracranial pressure and even mortality, a critical point remains the definition of good or acceptable outcome.

    Acute hemorrhagic edema of infancy (AHEI) is a cutaneous vasculitis seen in children. Many consider it to be a clinical variant of Schönlein-Henoch purpura, but others regard it as a separate entity because of its benign nature, age of onset, lack of visceral involvement, and frequent absence......, or vaccination. Because of the unknown etiology and benign character, which leads to spontaneous complete recovery, there is no specific treatment necessary for AHEI, and according to the literature, systemic corticosteroids do not seem to alter the course of the disease. We report the case of an 11-month......-old boy who manifested massive periorbital edema along with all of the clinical characteristics of this entity and showed clear improvement of the symptoms after a 24-hour administration of systemic corticosteroid therapy. Given the positive effect of this therapy, we propose that systemic corticosteroids...

    Edema formation frequently complicates brain infarction, tumors and trauma. Despite the significant mortality of this condition, current treatment options are often ineffective or incompletely understood. Recent studies have revealed the existence of a brain-wide paravascular pathway for cerebrospinal (CSF) and interstitial fluid (ISF) exchange. The current review critically examines the contribution of this ‘glymphatic’ system to the main types of brain edema. We propose that in cytotoxic edema, energy depletion enhances glymphatic CSF influx, whilst suppressing ISF efflux. We also argue that paravascular inflammation or ‘paravasculitis’ plays a critical role in vasogenic edema. Finally, recent advances in diagnostic imaging of glymphatic function may hold the key to defining the edema profile of individual patients and thus enable more targeted therapy. PMID:25236348

In addition, the effects of risk factors arc surveyed* This is an existing data study considering patients with clinically significant diabetic macular edema, treated with argon-green laser photocoagulation in Labbafinejad hospital, department of lasertherapy, from 1995 to 1997. in 60 (42.6% eyes the treatment method was focal, in 22 (15.6% eyes grid, and in 59 (41.84 modified grid laser photocoagulation was performed. The results are based upon deterioration of visual acuity, occurance of moderate visual loss and improvement or persistence of CSME. We studied 114 eyes from 87 patients. Two years after initial treatment, visual acuity improved in 19.1% of eyes, unchanged in 9.5% and worsened in 71.4% of eyes. After this period the rate of moderate visual loss was 28.6% and CSME was improved in 23.8% of eyes. According to our study, baseline visual acuity and retinopathy severity were two important intervening factors in response to lasertherapy. Comparing our results with natural course of diabetic macular edema, indicates that in assessing visual outcome laser photocoagulation is an effective modality in treatment of CSME, but it is not effective in maintaining or improving visual acuity, which is due to patients delay in visiting ophthalmologists and paying not enough attention to follow-up visits.

    To assess changes in retinal vascular caliber in response to short-term use of nepafenac eye drops in patients with mild diabetic macular edema. Thirty-four patients with previously untreated bilateral mild diabetic macular edema were included in this prospective study. For each participant, one eye was randomly assigned to nepafenac treatment (0.1%, three times/day) and the other eye was left untreated throughout the study. Using digital fundus photographs, retinal vascular calibers were calculated and compared in treated and untreated eyes at the baseline, week 1, and week 6. Baseline vessel diameters did not differ in treated and fellow eyes (p > 0.05). Over the 6 weeks of the study, significant vasoconstriction of the retinal arteriolar caliber was observed at weeks 1 (p  0.44). Significant macular thickness difference was only observed at week 6 (p = 0.002). Topical nepafenac has a significant narrowing effect on the retinal arteriolar diameter and a significant reductive effect on central macular thickness in eyes with mild diabetic retinopathy.

    To evaluate chest radiographic criteria in distinguishing mechanisms of pulmonary edema, the authors studied 45 intubated patients with extensive edema. Edema type was clinically classified by the ratio of alveolar edema-to-plasma protein concentration in association with compatible clinical/hemodynamic parameters. Chest films were scored as hydrostatic, permeability, or mixed by three readers in blinded fashion based on cardiac size, vascular pedicle width, distribution of edema, effusions, peribronchial cuffs, septal lines, or air bronchograms. Overall radiographic score accurately identified 87% of patients with hydrostatic edema but only 60% of those with permeability edema. Edema distribution was most discriminating, with a patchy peripheral pattern relatively specific for clinical permeability edema. Hydrostatic features on chest radiograph were common with permeability edema, including effusions (36%), widened pedicle (56%), cuffs (72%), or septa (40%). The authors conclude that the chest radiograph is limited in distinguishing edema mechanism in the face of extensive pulmonary edema

    Full Text Available Simultaneous bilateral primary pneumothorax is a very rare (1.6 / 100,000 and life-threatening condition. Clinical presentation may vary from mild dyspnea to tension pneumothorax. It may be milder particularly in younger patients, but more severe in patients with advanced age, and tube thoracostomy is a life preserver in the latter group. Since mortality and recurrence rates following tube thoracostomy are high, endoscopic approaches to bilateral hemithorax have been reported in literature. Apical wedge resection and pleural procedures are recommended in video thoracoscopy or mini thoracotomy even if no bulla and/or bleb are detected. Bilateral surgical interventions and additional pleural procedures are associated with increased rate of post-operative complications and longer postoperative hospital-stays. As a first-line approach, the surgical method toward any side of lung with air leakage following a previous tube thoracostomy is considered less invasive, especially in younger patients. Here, we present a case of simultaneous bilateral primary spontaneous pneumothorax (SBPSP in a 21-year old male with no history of smoking and chronic pulmonary disease. A unilateral surgical intervention was performed, and no recurrence was observed during 5-year follow up.

    We report a 51-year-old man with a dural arteriovenous fistula (DAVF) associated with bilateral thalamic lesions. He was admitted to our hospital because of cognitive disorder. T2-weighted MRI and fluid-attenuated inversion recovery (FLAIR) sequence of the brain revealed symmetric hyperintense lesions of bilateral thalamus and abnormal flow void that represents the enlarged veins. Cerebral angiography demonstrated DAVF in the superior petrosal sinus (SPS). It was mainly supplied by the internal carotid arteries. The strait sinus was not revealed, and the venous drainage was retrograde into the internal cerebral vein. Therefore the mechanism of cognitive disorder in this case was considered to be vasogenic edema of the bilateral thalamus due to DAVF of SPS. We decided to treat the DAVF by embolization via the feeding arteries approach, because strait sinus was not revealed and venous approach was difficult. After embolization, the size of DAVF was remarkably reduced. His cognitive disorder was markedly improved and the hyperintense area on T2-weighted MRI and FLAIR sequence had disappeared. Cognitive disorder due to DAVF of SPS is very rare. It is also difficult to diagnose bilateral thalamic lesions as DAVF, but it may be reversible by DAVF treatment. Thus, early diagnosis and treatment is important. Like this case, abnormal flow void that represents the enlarged veins could help to diagnose bilateral thalamic lesions due to DAVF.

    The chemical toxins in smoke and not the heat are responsible for the pulmonary edema of smoke inhalation. We developed a synthetic smoke composed of carbon particles (mean diameter of 4.3 microns) to which toxins known to be in smoke, such as HCl or acrolein, could be added one at a time. We delivered synthetic smoke to dogs for 10 min and monitored extravascular lung water (EVLW) accumulation thereafter with a double-indicator thermodilution technique. Final EVLW correlated highly with gravimetric values (r = 0.93, P less than 0.01). HCl in concentrations of 0.1-6 N when added to heated carbon (120 degrees C) and cooled to 39 degrees C produced airway damage but no pulmonary edema. Acrolein, in contrast, produced airway damage but also pulmonary edema, whereas capillary wedge pressures remained stable. Low-dose acrolein smoke (less than 200 ppm) produced edema in two of five animals with a 2- to 4-h delay. Intermediate-dose acrolein smoke (200-300 ppm) always produced edema at an average of 147 +/- 57 min after smoke, whereas high-dose acrolein (greater than 300 ppm) produced edema at 65 +/- 16 min after smoke. Thus acrolein but not HCl, when presented as a synthetic smoke, produced a delayed-onset, noncardiogenic, and peribronchiolar edema in a roughly dose-dependent fashion.

    Massive ovarian edema is a rare benign condition that predominantly affects childbearing women as well as preadolescent girls. It is thought to result from intermittent or partial torsion of the ovary compromising the venous and lymphatic drainage but with preserved arterial supply. The clinical features of massive ovarian edema are nonspecific and can simulate tumors, leading to unnecessary oophorectomy. To demonstrate imaging features that should alert radiologists to consider the diagnosis of massive ovarian edema preoperatively so that fertility-sparing surgery may be considered. We identified five girls diagnosed with massive ovarian edema at pathology. Presenting symptoms, sidedness, imaging appearance, preoperative diagnosis, and operative and histopathological findings were reviewed. Age range was 9.6-14.3 years (mean age: 12.5 years). Common imaging findings included ovarian enlargement with edema of the stroma, peripherally placed follicles, isointense signal on T1-W MRI and markedly hyperintense signal on T2-W MRI, preservation of color Doppler flow by US, and CT Hounsfield units below 40. The uterus was deviated to the affected side in all patients. Two of the five patients had small to moderate amounts of free pelvic fluid. Mean ovarian volume on imaging was 560 mL (range: 108-1,361 mL). While the clinical presentation of massive ovarian edema is nonspecific, an enlarged ovary with stromal edema, peripherally placed follicles and preservation of blood flow may be suggestive and wedge biopsy should be considered intraoperatively to avoid unnecessary removal of the ovary.

    Full Text Available Because the brain edema has a crucial impact on morbidity and mortality, it is important to develop a noninvasive method to monitor the process of the brain edema effectively. When the brain edema occurs, the optical properties of the brain will change. The goal of this study is to access the feasibility and reliability of using noninvasive near-infrared spectroscopy (NIRS monitoring method to measure the brain edema. Specifically, three models, including the water content changes in the cerebrospinal fluid (CSF, gray matter and white matter, were explored. Moreover, these models were numerically simulated by the Monte Carlo studies. Then, the phantom experiments were performed to investigate the light intensity which was measured at different detecting radius on the tissue surface. The results indicated that the light intensity correlated well with the conditions of the brain edema and the detecting radius. Briefly, at the detecting radius of 3.0cm and 4.0cm, the light intensity has a high response to the change of tissue parameters and optical properties. Thus, it is possible to monitor the brain edema noninvasively by NIRS method and the light intensity is a reliable and simple parameter to assess the brain edema.

    Diagnosing the underlying cause of acute dyspnea can be challenging. Lung ultrasound may help to identify pulmonary edema as a possible cause. To evaluate the ability of residents to recognize pulmonary edema on lung ultrasound using chest radiographs as a comparison standard. This is a prospective, blinded, observational study of a convenience sample of resident physicians in the Departments of Emergency Medicine (EM), Internal Medicine (IM), and Radiology. Residents were given a tutorial on interpreting pulmonary edema on both chest radiograph and lung ultrasound. They were then shown both ultrasounds and chest radiographs from 20 patients who had presented to the emergency department with dyspnea, 10 with a primary diagnosis of pulmonary edema, and 10 with alternative diagnoses. Cohen's κ values were calculated to describe the strength of the correlation between resident and gold standard interpretations. Participants included 20 EM, 20 IM, and 20 Radiology residents. The overall agreement with gold standard interpretation of pulmonary edema on lung ultrasound (74%, κ = 0.51, 95% confidence interval 0.46-0.55) was superior to chest radiographs (58%, κ = 0.25, 95% confidence interval 0.20-0.30) (P pulmonary edema with lung ultrasound than with chest radiograph. Physicians with minimal exposure to lung ultrasound may be able to correctly recognize pulmonary edema on lung ultrasound.

    Cerebral edema associated with brain tumors is extremely common and can occur in both primary and metastatic tumors. The edema surrounding brain tumors results from leakage of plasma across the vessel wall into the parenchyma secondary to disruption of the blood-brain barrier. The clinical signs of brain tumor edema depend on the location of the tumor as well as the extent of the edema, which often exceeds the mass effect induced by the tumor itself. Uncontrolled cerebral edema may result in increased intracranial pressure and acute herniation syndromes that can result in permanent neurological dysfunction and potentially fatal herniation. Treatment strategies for elevated intracranial pressure consist of general measures, medical interventions, and surgery. Alhough the definitive treatment for the edema may ultimately be surgical resection of the tumor, the impact of the critical care management cannot be underestimated and thus patients must be vigilantly monitored in the intensive care unit. In this review, we discuss the pathology, pathophysiology, and clinical features of patients presenting with cerebral edema. Imaging findings and treatment modalities used in the intensive care unit are also discussed. © The Author(s) 2015.

    Full Text Available Objectives: To investigate the epidemiology and frequency of serous macular detachment (SMD in patients diagnosed with diabetic macular edema (DME. Materials and Methods: Hundred and forty-three eyes of 104 patients with DME were examined retrospectively. According to the results of OCT, the patients were separated into two groups; patients diagnosed with SMD and DME (group 1 and patients diagnosed with DME (group 2. They were assessed based on demographic characteristics, average age, duration of diabetes mellitus (DM, hypertension (HT history, best-corrected visual acuity, and diabetic retinopathy stages. Results: The average age of the patients was 61±8.7 years. Forty-three patients (41.3% were female and 61 patients (58.7% were male. Fifty-four of 104 patients (51.9% had DME with SMD. 21 (38.8% patients had bilateral SMD. In group 1, 31 patients were male (57.4% and 23 patients were female (42.6%. In group 2, 30 (60% patients were male and 20 (40% patients were female. In group 1, average age was 60.2±9.6 and the average duration of DM was 12.2±7.0 years, whereas the average age was 61.9±7.6 and the average duration of DM was 14.06±6.8 years in group 2. Forty-two patients in group 1 (77.8% and 30 patients (60% in group 2 had history of HT. Before the treatment, the average best-corrected visual acuity was found to be 0.30±0.24 in group 1 and 0.32±0.25 in group 2. Conclusion: Today, it is thought that diabetic maculopathy is the leading cause of SMD and it is a determining factor of treatment applications. In our study, we aimed at investigating the frequency of SMD in DME and the risk factors for the development of SMD. Although there were some differences between the factors, only the history of HT was found statistically higher in patients with SMD (p=0.04. (Turk J Ophthalmol 2015; 45: 92-96

    2013-04-01

    Full Text Available Background: The essential features of Posterior Reversible Encephalopathy Syndrome (PRES are headache, mental changes, seizures, visual symptoms and often arterial hypertension. Brain RMN typically shows cortico-sottocortical parieto-occipital edema, with a bilateral and symmetric distribution. PRES develops in clinical conditions as hypertensive encephalopathy, preeclampsia/ eclampsia, autoimmune diseases, after transplantation, infections and as an adverse effect of immunosuppressive drugs or chemotherapy. It usually completely reverses with treatment, although permanent sequelae are possible in case of delayed or missed diagnosis. Case report: We describe the case of a transsexual (M!F and tetraplegic patient, admitted for neck and low back pain. She suddenly developed headache, confusion, seizures and severe hypertension with normal blood tests. RMN showed multiple cortico-sottocortical areas of vasogenic and citotoxic edema in temporo-occipital, parietal, frontal, and cerebellar regions. Soon after the beginning of the antihypertensive therapy, clinical recovery was observed, as well as the disappearance of edema at RMN. Discussion and conclusions: Although PRES is usually associated with definite pathological conditions, it is not always the case, as was for the patient here described, who had no predisposing factors in her past clinical history, and presented hypertension only in the acute phase of the syndrome. Since, moreover, PRES usually presents with acute non specific features and it can be misdiagnosed with other serious diseases, the clinician will be helped by the knowledge of this syndrome to promptly start diagnostic workup and treatments, and avoid permanent neurological deficits.

    Retinal Vein Occlusions are vascular diseases affecting the Central Retinal Vein and its branches causing decreased retinal drainage resulting in significant clinical and functional pathological changes. RVO determines the increase of vascular permeability, with edema and hemorrhage and development of collateral vessels in a few weeks. Among the serious consequences of venous occlusion is the installation of macular edema to which depends long-term visual prognosis. Macular Edema is the accumulation of intraretinal serous fluid in the macular area caused by the breakdown of blood-retinal barrier.

    Full Text Available Diabetic macular edema (DME can cause blindness in diabetic patients suffering from diabetic retinopathy (DR. DM parameters controls (glycemia, arterial tension, and lipids are the gold standard for preventing DR and DME. Although the vascular endothelial growth factor (VEGF is known to play a role in the development of DME, the pathological processes leading to the onset of this disease are highly complex and the exact sequence in which they occur is still not completely understood. Angiogenesis and inflammation have been shown to be involved in the pathogenesis of this disease. However, it still remains to be clarified whether angiogenesis following VEGF overexpression is a cause or a consequence of inflammation. This paper provides a review of the data currently available, focusing on VEGF, angiogenesis, and inflammation. Our analysis suggests that angiogenesis and inflammation act interdependently during the development of DME. Knowledge of DME etiology seems to be important in treatments with anti-VEGF or anti-inflammatory drugs. Current diagnostic techniques do not permit us to differentiate between both etiologies. In the future, diagnosing the physiopathology of each patient with DME will help us to select the most effective drug.

    Currently, the optimal surgical approach for bilateral aneurysms remains controversial. Alternative interventional methods, such as unilateral or bilateral approaches, have been used during a single session or 2 different sessions. The unilateral approach can be used successfully to treat contralateral aneurysms that develop in a paramedian location. However, such an approach is more difficult for treating contralateral aneurysms in more distant locations. The unilateral approach can decrease complication rates, operation time, and length of hospital stay. In this study, we aimed to identify when the unilateral approach should be chosen in patients with bilateral middle cerebral artery (MCA) aneurysms and to compare the effect of each approach on the operation time and duration of hospital stay. Between March 2003 and May 2016, 17 bilateral MCA aneurysms were diagnosed in patients who presented to our clinic with complaints of headache and a diagnosis of subarachnoid hemorrhage. The extent of the cerebral edema, A1 + M1 distance on the opposite site, and configuration of the contralateral aneurysm were determined by preoperative radiologic studies. Based on these findings, 7 patients underwent unilateral surgery, and 10 patients received the bilateral approach. The 2 groups had a very similar postoperative course. Nonetheless, the operation time and hospital stay were significantly longer for patients who underwent bilateral surgery than those treated with the unilateral approach. In selected patients with bilateral MCA aneurysms, the unilateral approach is a favorable alternative that is less invasive, decreases the operation time and hospital stay, and leads to fewer complications.

    Full Text Available Lymphoma involving the lacrimal gland is rare. Most of the cases are unilateral at presentation. In this case, we present the diagnostic evaluation of a patient with bilateral lacrimal gland lymphoma. At presentation, the patient had inferomedial eccentric proptosis of the right eye. The patient also had limitation in the upper and lateral gaze in this eye. On magnetic resonance imaging, a mass was detected not only in the right but also in the left eye corresponding to the area of the lacrimal gland. Excisional biopsy was performed in the right eye with lateral orbitotomy approach. Histopathological examination revealed extranodal marginal zone lymphoma involving the lacrimal gland. No concurrent systemic lymphoma was detected during systemic evaluation of the patient. The patient was directed to the oncology department for systemic treatment planning. In conclusion, bilateral involvement is rare in lacrimal gland diseases but it can show severe diseases like lymphoma.

    Full Text Available Pulmonary edema is a potentially life-threatening complication of acute airway obstruction. It develops rapidly, without warning, in young healthy individuals. Two forms of post-obstructive pulmonary edema (POPE (also known as negative pressure pulmonary edema, NPPE have been identified. POPE I follows sudden, severe upper airway obstruction. POPE II occurs following surgical relief of chronic upper airway obstruction. Treatment for both is supportive. Full and rapid recovery can be expected with appropriate management. A case report of a middle aged man with acute onset epiglottitis who developed negative pressure pulmonary edema after intubation is presented. The report includes a brief discussion on etiology, clinical features and management dilemma of acute upper airway obstruction.

    To discuss the possible etiopathogenetic mechanism of inner ear damage induced by the ingestion of potassium hydroxide (KOH). We report the case of a 37-year-old patient with sudden bilateral sensorineural hearing loss after accidental ingestion of a KOH solution. The first ear, nose and throat examination disclosed only mild edema of the upper airways. He was treated in the intensive care unit and prescribed high-dose steroids, proton pump inhibitors and sucralfate for 2 weeks. Unfortunately, there was no recovery of the hearing loss, and no audiogram changes were noticed after 12 months of follow-up. After exploring the possible etiopathogenetic mechanism involved, the authors believe that in this case, a transient severe hemodynamic imbalance can actually be considered to be the most reliable explanation for the inner ear damage and subsequent onset of permanent bilateral sensorineural hearing loss.

    Full Text Available Acute hemorrhagic edema of infancy is an uncommon benign cutaneous vasculitis. Despite its worrisome presentation, it carries good prognosis with rarely reported systemic involvement. Management of these cases has been an area of debate with majority of physicians adopting conservative modalities. We report a case that presented with classic triad of rash, low grade fever, and peripheral edema along with two rarely reported manifestations in literature: hemorrhagic lacrimation and epistaxis.

    Ischemic edema can alter the structure and permeability of the blood-brain barrier. Recent studies have reported that progesterone reduces cerebral edema after cerebral ischemia. However, the underlying mechanism of this effect has not yet been elucidated. In the present study, progesterone effectively reduced Evans blue extravasation in the ischemic penumbra, but not in the ischemic core, 48 hours after cerebral ischemia in rats. Progesterone also inhibited the down-regulation of gene and pr...

    Focal hand dystonia in musicians, also known as musician's dystonia, is a task-specific movement disorder characterized by unwanted involuntary muscle contractions occurring only when playing a musical instrument. Case 1 was a 50-year-old female professional pianist who underwent staged bilateral ventro-oral (Vo) thalamotomy, with an interval between the first and second surgery of 4 years. The first surgery (right Vo thalamotomy) led to significant improvements in dystonic symptoms without any complications. Pre- and postoperative Tubiana's musician's dystonia scale (TMDS) scores were 2 and 5, respectively. The second surgery (left Vo thalamotomy) also led to significant improvements in dystonic symptoms, with dysarthria and verbal recall disturbance resolving within 3 months. Pre- and postoperative TMDS scores were 2 and 5, respectively. The patient was subsequently able to return to live-stage performances. Case 2 was a 48-year-old male clarinet repair technician who underwent staged bilateral Vo thalamotomy, with an interval between the first and second surgery of 13 months. The first surgery (right Vo thalamotomy) led to dramatic improvements in symptoms without any complications. Pre- and postoperative TMDS scores were 2 and 5, respectively. The second surgery (left Vo thalamotomy) also led to significant improvements in symptoms with transient hypophonia. Pre- and postoperative TMDS scores were 2 and 5, respectively. The patient was subsequently able to return to work without difficulty. The findings in these 2 cases indicate the utility of bilateral stereotactic Vo thalamotomy in the treatment of medically intractable musician's dystonia affecting both hands.

    Generalized edema is a major presenting clinical feature of children with nephrotic syndrome (NS) exemplified by such primary conditions as minimal change disease (MCD). In these children with classical NS and marked proteinuria and hypoalbuminemia, the ensuing tendency to hypovolemia triggers compensatory physiological mechanisms, which enhance renal sodium (Na(+)) and water retention; this is known as the "underfill hypothesis." Edema can also occur in secondary forms of NS and several other glomerulonephritides, in which the degree of proteinuria and hypoalbuminemia, are variable. In contrast to MCD, in these latter conditions, the predominant mechanism of edema formation is "primary" or "pathophysiological," Na(+) and water retention; this is known as the "overfill hypothesis." A major clinical challenge in children with these disorders is to distinguish the predominant mechanism of edema formation, identify other potential contributing factors, and prevent the deleterious effects of diuretic regimens in those with unsuspected reduced effective circulatory volume (i.e., underfill). This article reviews the Starling forces that become altered in NS so as to tip the balance of fluid movement in favor of edema formation. An understanding of these pathomechanisms then serves to formulate a more rational approach to prevention, evaluation, and management of such edema.

    Postoperative pulmonary edema is a well-known postoperative complication caused as a result of numerous etiological factors which can be easily detected by a careful surveillance during postoperative period. However, there are no preoperative and intraoperative criteria which can successfully establish the possibilities for development of postoperative pulmonary edema. The aims were to review the possible etiologic and diagnostic challenges in timely detection of postoperative pulmonary edema and to discuss the various management strategies for prevention of this postoperative complication so as to decrease morbidity and mortality. The various search engines for preparation of this manuscript were used which included Entrez (including Pubmed and Pubmed Central), NIH.gov, Medknow.com, Medscape.com, WebMD.com, Scopus, Science Direct, MedHelp.org, yahoo.com and google.com. Manual search was carried out and various text books and journals of anesthesia and critical care medicine were also searched. From the information gathered, it was observed that postoperative cardiogenic pulmonary edema in patients with serious cardiovascular diseases is most common followed by noncardiogenic pulmonary edema which can be due to fluid overload in the postoperative period or it can be negative pressure pulmonary edema (NPPE). NPPE is an important clinical entity in immediate post-extubation period and occurs due to acute upper airway obstruction and creation of acute negative intrathoracic pressure. NPPE carries a good prognosis if promptly diagnosed and appropriately treated with or without mechanical ventilation.

  11. [Macular Edema in Uveitis - Steroids or VEGF Inhibitors?

    2017-06-09

    Macular edema in uveitis patients is certainly the most frequent complication leading to a permanent and irreversible reduction in vision during the course of the disease. Thanks to optical coherence tomography (OCT) technology and fluorescein angiography (FAG), significantly more macular edemas are detected. Macular edema can be found in various uveitis varieties and can show different clinical patterns. All macular edema should be treated. Macular edema with active inflammation usually reacts very well to general uveitis treatment. In the case of eyes without visible inflammation, however, the response to such therapy is usually less effective. According to the latest treatment recommendations, dexamethasone implants should be used as the first intravitreal therapy. Vascular endothelial growth factor inhibitors (VEGF inhibitors) are second-line treatment regimens. The choice of therapy is, therefore, primarily based on the degree of inflammation and the individual complications, such as glaucoma, lens situation or previous increase in IOP after steroid administration. These individual complications may allow using VEGF inhibitors as first line treatment. An improvement in the macular edema can be achieved with both groups of active substances.

    To access the CT findings of pulmonary edema and to compare them, according to the cause. CT findings (thin section, 20 ; thick section, 16) of pulmonary edema in 36 patients [cardiac disease (group 1, n=20), renal disease (group 2, n=13), ARDS (group 3, n=3)] were analyzed and compared. There were 21 men and 15 women ranging in age from 27 to 77 years. Distribution (even, central, or peripheral) and patterns of pulmonary edema were compared between the three groups. The distribution of edema, appearing as consolidation or ground-glass opacity, was even in 75% (n=15) of group 1, even in 46% (n=6) and central in 38% (n=5) of group 2, and peripherally predominant in 100% (n=3) of group 3. Interlobular septal thickening was seen in 80% (n=16), 69% (n=9), and 0% of group 1, 2 and 3, respectively. Centrilobular ground-glass opacity was noted in six patients. In spite of various findings and considerable overlapping of the findings of pulmonary edema, the distribution and pattern of edema differed according to the cause, and this can be helpful for differential diagnosis

  13. The spreading of focal brain edema induced by ultraviolet irradiation

    1978-01-01

    Focal brain edema limited to one cerebral hemisphere was produced by ultraviolet irradiation of the exposed cortex. Tissue water content was determined by the gravimetric method which allows microsampling. Therefore, the spread of edema around the small necrotic area be mapped more precisely than by determination of dry weight which calls for larger samples. As early as 30 min after irradiation, hyperemia and swelling of the brain are observed under the operating microscope. This correlates with venous stasis, hyperemia, and broadened perivascular spaces around venules and large capillaries accompanied by a marked rise in the specific weigth of the tissue. After 4h an edema front can be observed spreading from the perinerotic zone in which there is a marked rise in endothelial cell vesicular activity. Edema reaches maximum levels in the deep white matter at 48h post irradiation with normalisation of the tissue water content after 96h. The velocity at which the edema front spreads from the cortex to the periventricular area lies in the range of 0.25mm/h. Edema reabsorption coincides with signs of retrograde micropinocytosis in endothelial cells. (orig./AJ) [de

  14. Aquaporin-4: A Potential Therapeutic Target for Cerebral Edema

    2016-01-01

    Aquaporin-4 (AQP4) is a family member of water-channel proteins and is dominantly expressed in the foot process of glial cells surrounding capillaries. The predominant expression at the boundaries between cerebral parenchyma and major fluid compartments suggests the function of aquaporin-4 in water transfer into and out of the brain parenchyma. Accumulating evidences have suggested that the dysregulation of aquaporin-4 relates to the brain edema resulting from a variety of neuro-disorders, such as ischemic or hemorrhagic stroke, trauma, etc. During edema formation in the brain, aquaporin-4 has been shown to contribute to the astrocytic swelling, while in the resolution phase, it has been seen to facilitate the reabsorption of extracellular fluid. In addition, aquaporin-4-deficient mice are protected from cytotoxic edema produced by water intoxication and brain ischemia. However, aquaporin-4 deletion exacerbates vasogenic edema in the brain of different pathological disorders. Recently, our published data showed that the upregulation of aquaporin-4 in astrocytes probably contributes to the transition from cytotoxic edema to vasogenic edema. In this review, apart from the traditional knowledge, we also introduce our latest findings about the effects of mesenchymal stem cells (MSCs) and microRNA-29b on aquaporin-4, which could provide powerful intervention tools targeting aquaporin-4.

    Concerning a hydraulic bilateral construction robot, its system constitution, structures and functions of important components, and the results of some tests are explained, and the researches conducted at Gifu University are described. The construction robot in this report is a servo controlled system of a version developed from the mini-shovel now available in the market. It is equipped, in addition to an electrohydraulic servo control system, with various sensors for detecting the robot attitude, vibration, and load state, and with a camera for visualizing the surrounding landscape. It is also provided with a bilateral joy stick which is a remote control actuator capable of working sensation feedback and with a rocking unit that creates robot movements of rolling, pitching, and heaving. The construction robot discussed here, with output increased and response faster thanks to the employment of a hydraulic driving system for the aim of building a robot system superior in performance to the conventional model designed primarily for heavy duty, proves after tests to be a highly sophisticated remotely controlled robot control system.

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    In a 48-year-old otherwise healthy man, a bilateral common peroneal palsy was diagnosed clinically and neurophysiologically. He reported on strength training with weights in both arms, lifting the weights and his upper body from a deep squatting position with broadly positioned legs akimbo in a hitherto unusual intensity. Regarding the pathophysiological mechanisms, 2 options are considered: first, stretching of the nerve at the fascia of the peroneal longus muscle and along the fibula neck, and second, compression of the nerve during squatting with weights loaded and with strongly activated anterior tibial and peroneal muscles.

    Full Text Available Introduction. In 1814 Giovanni Monteggia first described two cases of fractures of the proximal third of ulna with dislocation of the radial head. These fractures are more common in children than in adults, and mutual Monteggia fracture is a rare complication. This study presents a treatment course of a patient with bilateral Monteggia fracture. Case report. A 55- year-old patient was injured by falling in the yard. Radiography showed bilateral Monteggia fracture type II (by the Badon classification. Operative treatment of fracture was done by a compression plate on the right side and by the zuggurtung technique on the left one. Closed repositioning of the radial head was done on both sides. The patient was wearing a plaster splint for the upper arm for 21 days. After removing the fixation, the function of the elbow was determined by the Broberg Morrey score (BM which was on the right side 45.5 and on the left side 47.5. After the proper physical therapy, four months after the surgery, BM score was 100 on the right side, and 93 on the left one. Conclusion. Surgical treatment and early rehabilitation is the key for the return of good function of both elbows.

    To investigate the factors contributing to pioglitazone-induced edema, we analyzed sodium excretion and several clinical parameters before and after administration of pioglitazone. We analyzed these parameters before and after 8 weeks of administration of pioglitazone to female subjects with type 2 diabetes. When we evaluated whether a significant correlation was found between salt excretion and blood pressure, six patients showed such correlation and 20 patients did not. After 8 weeks of pioglitazone administration, five patients had developed edema, and, surprisingly, such correlation was not found in all five subjects. Salt excretion after administration of pioglitazone was significantly lower in subjects who developed edema and those who showed the correlation, and the hematocrit was significantly lower after administration in the subjects who showed the correlation, but not in the edema group. Pioglitazone-induced edema would be caused not only by fluid retention, but also by other factors, such as vascular permeability. (J Diabetes Invest, doi: 10.1111/ j.2040-1124.2010.00046.x, 2010).

    Global cerebral edema is common among patients with poor-grade subarachnoid hemorrhage and is associated with poor outcome. Currently no targeted therapy exists largely due to an incomplete understanding of the underlying mechanisms. This is a prospective observational study including 39 consecutive patients with poor-grade subarachnoid hemorrhage with multimodal neuromonitoring. Levels of microdialysate lactate-pyruvate ratio, episodes of cerebral metabolic crisis (lactate-pyruvate ratio >40 and brain glucose cerebral perfusion pressure, and transcranial Doppler sonography flow velocities were analyzed. Median age was 54 years (range, 45 to 61 years) and 62% were female. Patients with global cerebral edema on admission (n=24 [62%]) had a higher incidence of metabolic crisis in the first 12 hours of monitoring (n=15 [15% versus 2%], Pcerebral edema. There was no difference in brain tissue oxygen tension or cerebral perfusion pressure between the groups; however, in patients with global cerebral edema, a higher cerebral perfusion pressure was associated with lower lactate-pyruvate ratio (Pcerebral edema is associated with early brain metabolic distress.

    Acute pediatric encephalitis with fulminant cerebral edema can rapidly become fatal or result in devastating neurological sequelae. All cases coded with the discharge diagnosis of acute encephalitis between January 2000 and December 2010 were reviewed. Of the 1038 children with acute pediatric encephalitis, 25 were enrolled in our study with ages ranging from 5 months to 16 years. The major neurological symptoms included an altered level of consciousness (72%), vomiting (60%), and headache (48%). The onset of neurological symptoms to signs of brain herniation ranged from 0 days to 9 days. Nineteen (76%) patients had a seizure 24-48 hours prior to showing signs of fulminant cerebral edema, and 12 (48%) patients developed status epilepticus. Sixteen patients died, and no survivors returned to baseline. Risk factors for seizures and status epilepticus were compared between the fulminant cerebral edema group (n = 25, 19 seizures, including 12 status epilepticus) and control group (nonfulminant cerebral edema) (n = 1013, 444 seizures, including 141 status epilepticus; p = 0.001 for seizures and p cerebral edema in children with acute encephalitis.

    A portable external pneumatic intermittent compression (EPIC) device has been successful in reducing peripheral edema. This study explored the effectiveness of EPIC for treating dependent pregnancy edema. In the study, 42 healthy pregnant women received EPIC for 30 minutes at 40 torr while in the left lateral recumbent position: Group One with mid-thigh boots, and Group Two with below-knee boots. Prior to compression, descriptive data were gathered, leg circumference measurements made, and surface skin temperatures recorded for three sites per leg. Vital signs were taken and pedal edema subjectively indexed. Following compression, circumferences, skin temperatures, vital signs, and edema indices were rerecorded. Three volumes were calculated for each leg using a mathematical model of leg segments as conical frustum units. Mean volume reductions for each leg were significant. The mid-thigh-length boots produced greater mean volume decreases. The volume decrease for calf, lower leg, and foot frustum units were significant. EPIC holds promise as a useful treatment for dependent pregnancy edema.

    To evaluate the effect of internal limiting membrane (ILM) peeling during vitrectomy for nontractional diabetic macular edema. PUBMED, MEDLINE and CENTRAL were reviewed using the following terms (or combination of terms): diabetic macular edema, nontractional diabetic macular edema, internal limiting membrane peeling, vitrectomy, Müller cells. Randomized and nonrandomized studies were included. The eligible studies compared anatomical and functional outcomes of vitrectomy with or without ILM peeling for tractional and nontractional diabetic macular edema. Postoperative best-corrected visual acuity and central macular thickness were considered, respectively, the primary and secondary outcomes. Meta-analysis on mean differences between vitrectomy with and without ILM peeling was performed using inverse variance method in random effects. Four studies with 672 patients were eligible for analysis. No significant difference was found between postoperative best-corrected visual acuity or best-corrected visual acuity change of ILM peeling group compared with nonpeeling group. There was no significant difference in postoperative central macular thickness and central macular thickness reduction between the two groups. The visual acuity outcomes in patients affected by nontractional diabetic macular edema using pars plana vitrectomy with ILM peeling versus no ILM peeling were not significantly different. A larger prospective and randomized study would be necessary.

    Imatinib mesylate (Gleevec) is a chemotherapy medication developed to treat chronic myelogenous leukemia as well as gastrointestinal stromal tumors (Savage, N Engl J Med 2002;346:683-93). Ocular side effects are commonly reported with the use of imatinib mesylate, such as periorbital edema and epiphora. More serious ocular side effects, such as optic disc edema, are rarely reported. This case is of a patient who presented with monocular painless loss of vision in the left eye from a previously documented 20/20 to 20/70 shortly after starting treatment with imatinib mesylate. Every aspect of the ocular presentation and clinical history were addressed to unveil the cause of the disc edema. After ruling out all other causes, the patient was later diagnosed with unilateral optic disc edema as a related side effect of the toxicity from imatinib mesylate. The properties of imatinib mesylate and the possible etiology of secondary optic disc edema are discussed. This study aims to highlight the importance of systemic medications review for possible etiology of ocular disease as well as the multidisciplinary approach to managing oncology patients with ocular side effects.

    Distinguishing between vasogenic edema and reactive astrogliosis may be difficult in some instances. This study was performed to test the hypothesis that diffusion-weighted (DW) imaging with apparent diffusion coefficient (ADC) maps can be used to differentiate these two types of changes. The study population included 11 patients with perilesional vasogenic edema and 11 patients with gliosis examined with conventional MR imaging and DW imaging. The signal intensities of conventional pulse sequences and ADC values were calculated in regions of interest placed in the hyperintense edematous or gliotic regions and compared with those of normal-appearing white matter. Signal intensity ratios and ADC values in gliosis were compared with those in vasogenic edema using the Mann-Whitney U-test. While considerable overlap was present for signal intensity ratios on conventional MR images, areas of gliosis demonstrated significantly higher ADC values (1.76 {+-} 0.09 x 10{sup -3} mm{sup 2}/s) than areas of vasogenic edema (1.35 {+-} 0.06 x 10{sup -3} mm{sup 2}/s; P < 0.0001) without overlap. ADC values are helpful in differentiating reactive gliosis from vasogenic edema. (orig.)

    Full Text Available Supernumerary teeth are more common in the permanent than in primary dentition. In the primary dentition, the anomaly is most frequently observed in the maxillary lateral incisor region, followed by the maxillary midline where they are termed as mesiodens. Supernumerary teeth in the primary canine region are rare. This paper describes a rare case of nonsyndromic supernumerary primary maxillary canine distributed bilaterally in a 4-year-old boy. Both the supernumeraries resembled size and shape of normal primary canine. The right supplemental canine is high labially placed, whereas the left one is seen normally aligned in the dental arch distal to lateral incisor. One of the most significant sequelae of primary supernumerary teeth is their duplication in the permanent series. Radiographic examination of supernumerary primary canine did not indicate any such anomaly in the permanent dentition. The patient was kept under observation.

    Four cases of bilateral internal carotid occlusion are reported with respect to clinical features, hemodynamics and various image diagnosis. MRI is applied to three cases. The patients comprised 2.08 % of all cerebral occlusive diseases treated during the past five years at our clinic. One case is of abrupt onset and three cases are progressing profiles. In one of these cases, collateral circulation is supplied mainly by leptomeningeal anastomosis of the posterior cerebral artery and posterior pericallosal artery branching from the basilar artery. In two of them, they are supplied through the circle of Willis. Middle cerebral artery occlusion, occlusion supra occlusionem, however, causes decisive ischemic lesion in its teritory. Applying MRI, complicated ischemic lesions, such as lacunar infarction, paraventricular lesion, deep white matter lesion and border zone infarction can clearly be identified. In the case of total aphasia, the lesions responsible are demonstrated clearly by MRI, but only vaguely by X-ray CT. (author)

    2016-01-01

    Full Text Available Immersion Pulmonary Edema (IPE is a unique medical condition being increasingly described in the medical literature as sudden-onset pulmonary edema in the setting of scuba diving and/or swimming. We report on three patients with unique presentations of IPE with associated development of Takotsubo cardiomyopathy (TTC. All three cases occurred in Oahu, Hawaii and were seen by the same cardiologist within a span of seven years. Each patient was scuba diving with sudden onset dyspnea with pulmonary edema on chest x-ray. Cardiac catheterization revealed no significant epicardial stenosis or thrombosis. EKGs showed typical evolution of symmetric T wave inversion. Wall motion abnormalities resolved. IPE and TTC may occur together and may be more common than initially thought. Physical and emotional stressors are known to trigger TTC. TTC should be considered as a possible complication of IPE. Initial workup should include EKGs, cardiac enzymes, echocardiogram and, in the appropriate situation, cardiac catheterization.

  17. Pathogenesis of optic disc edema in raised intracranial pressure.

    2016-01-01

    Optic disc edema in raised intracranial pressure was first described in 1853. Ever since, there has been a plethora of controversial hypotheses to explain its pathogenesis. I have explored the subject comprehensively by doing basic, experimental and clinical studies. My objective was to investigate the fundamentals of the subject, to test the validity of the previous theories, and finally, based on all these studies, to find a logical explanation for the pathogenesis. My studies included the following issues pertinent to the pathogenesis of optic disc edema in raised intracranial pressure: the anatomy and blood supply of the optic nerve, the roles of the sheath of the optic nerve, of the centripetal flow of fluids along the optic nerve, of compression of the central retinal vein, and of acute intracranial hypertension and its associated effects. I found that, contrary to some previous claims, an acute rise of intracranial pressure was not quickly followed by production of optic disc edema. Then, in rhesus monkeys, I produced experimentally chronic intracranial hypertension by slowly increasing in size space-occupying lesions, in different parts of the brain. Those produced raised cerebrospinal fluid pressure (CSFP) and optic disc edema, identical to those seen in patients with elevated CSFP. Having achieved that, I investigated various aspects of optic disc edema by ophthalmoscopy, stereoscopic color fundus photography and fluorescein fundus angiography, and light microscopic, electron microscopic, horseradish peroxidase and axoplasmic transport studies, and evaluated the effect of opening the sheath of the optic nerve on the optic disc edema. This latter study showed that opening the sheath resulted in resolution of optic disc edema on the side of the sheath fenestration, in spite of high intracranial CSFP, proving that a rise of CSFP in the sheath was the essential pre-requisite for the development of optic disc edema. I also investigated optic disc edema with

    Sulfite is commonly used in pharmaceuticals as a preservative. We report a unique clinical presentation of localized periorbital edema on the left eye after administration of sulfite-containing dexamethasone. The patient's sulfite sensitivity was confirmed by sulfite oral provocation test: periorbital edema on the same site developed after ingestion of 200 mg sodium bisulfite. She was non-atopic and did not complain of any respiratory symptoms. Allergy skin prick test with 100 mg/ml sodium bisulfite showed a negative result. She also has aspirin-sensitive urticaria which was confirmed by oral provocation test. In conclusion, sulfite can induce a localized periorbital edema, an uncommon manifestation in sensitive patients. Further investigations are needed to clarify the pathogenetic mechanisms.

    Full Text Available Discoid Lupus Erythematosus (DLE is an autoimmune disorder that usually occurs on sun exposed areas of head and neck. Infrequently it could be presented by palpebral involvement and rarely unilateral upper eye lid edema and erythema have been reported as the sole manifestation of DLE. We describe a 38-year-old woman with chronic left upper eye lid edema and erythema from one year ago which was induced by steroid injection for left eyebrow alopecia. Histopathologic and direct immunofluorescent studies were made on palpebral skin tissue and confirmed DLE diagnosis. Antinuclear antibody (ANA titer was 1/160 with speckled pattern. She was treated by oral hydroxychloroquine (400 mg daily with moderate improvement after three months. We should think about DLE in cases with chronic upper eye lid edema and erythema. The aim of this case report is to emphasize that ophthalmologist and dermatologists should be aware of different presentations of DLE in the periorbital area to prevent misdiagnosis.

    Acute hemorrhagic edema of infancy is a rare but benign vasculitis occurring in infants aged from 4 to 24 months. Skin lesions can take various forms, including extensive hemorrhagic purpura, and can therefore be mistaken for purpura fulminans if associated with fever, which leads to initiating broad-spectrum antibiotic treatment. In the present case, we describe a 7-month-old boy with acute hemorrhagic edema of infancy and rapidly extensive purpura lesions that led to intravenous cefotaxime and amikacin treatment. Diagnosis was made on the next day by a dermatologist, based on the typical aspect of skin lesions, hemodynamic stability, and negative bacteriological samples. Coxsackie virus B5, a pathogenic enterovirus, was found by specific PCR in cerebrospinal fluid. The outcome was spontaneously favorable after discontinuation of antibiotics on day 2. We discuss the imputability of the enterovirus in triggering this case of acute hemorrhagic edema of infancy. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Methodology: Routine transthoracic echocardiography, computed tomography scan of the thorax, magnetic resonance angiography of the renal arteries, and conventional digital subtraction angiography were applied. Comprehensive NF-1 mutation analysis was carried out by fluorescence in situ hybridization analysis, long-range reverse transcriptase polymerase chain reaction, and multiple-ligation probe assay. All other investigations were performed using routine, well-established techniques. Results: The subject is a 34-year-old, half-Chinese male; NF-1 was suspected at age 15 years for the first time. His medical history included preterm birth, mild facial dysmorphism, "café au lait" spots, subcutaneous and paravertebral fibromas, multifocal tachycardia, atrial fibrillation, and heart failure in early infancy. Noncalcified bone fibromas in the femur and tibia were detected at age 8 years. Surgical right leg lengthening was carried out at age 11 years. Bilateral renal artery stenosis, stenosis and aneurysm of the superior mesenteric artery, and an infrarenal aortic stenosis were detected at age 15 years. Leg edema and ectasia of the basilar artery were diagnosed at age 18 years. After an episode with an erysipela at age 34 years, he developed pericardial and pleural effusion during a 4-month period. Stenosis of the left subclavian vein at the level of thoracic duct insertion was detected. After repeated pleural punctures, pleural effusion was interpreted as chylothorax.

    Full Text Available Steven M Couch, Sophie J BakriMayo Clinic Department of Ophthalmology, Mayo Clinic, Rochester, MN, USAAbstract: Triamcinolone acetonide (TA is a corticosteroid that has many uses in the treatment of ocular diseases because of its potent anti-inflammatory and anti-permeability actions. Intraocular inflammation broadly referred to as uveitis can result from several causes, including the immune system and after ophthalmic surgery. One of the most common reasons for vision loss with uveitis is macular edema. TA has been used for many years as an intravitreal injection for the treatment of ocular diseases. Several case control studies have been reported showing the efficacy of TA in the treatment of intraocular inflammation and associated macular edema caused by Behcet’s disease, Vogt-Koyanagi-Harada syndrome, sympathetic ophthalmia and white dot syndromes. It has also been shown efficacious in cases of pars planitis and idiopathic posterior uveitis. Some authors have reported its use in postoperative cystoid macular edema. Many of the studies on the use of TA in controlling intraocular inflammation and concomitant macular edema showed its effect to be transient in many patients requiring reinjection. Complications can arise from intravitreal injection of TA including elevated intraocular pressure and cataract. Rarely, it can be associated with infectious and non-infectious endophthalmitis. TA may be useful as an adjuvant in the treatment of uveitis and its associated macular edema, especially in patients resistant or intolerant to standard treatment.Keywords: triamcinolone acetonide, Behcet’s disease, sympathetic ophthalmia, Vogt-Koyanagi-Harada syndrome, white dot syndromes, uveitis, cataract surgery, macular edema, endophthalmitis

Após tratamento específico, o paciente apresentou melhora tanto da acuidade visual quanto do aspecto fundoscópico. O achado de oclusão de veia central da retina bilateral pode levar ao diagnóstico de importantes doenças sistêmicas. os achados fundoscópicos podem servir de parâmetro na avaliação do tratamento.The authors report the case of a 16-year-old male patient who presented with blurred vision and bilateral optic disc edema, then developing bilateral central retinal vein occlusion. On laboratory work-up, he was found to have multiple myeloma IgA along with hyperviscosity syndrome, which led to the ophthalmological features. After proper treatment, the patient recovered visual acuity and normalized his eye fundus changes. Bilateral central retinal vein occlusion finding may yield the diagnosis of major systemic diseases. Fundoscopic features may serve as parameters on treatment evaluation.

    We report the case of a 70-year-old female patient who developed corneal edema and iris discoloration following the inadvertent use of 1% methylene blue instead of 0.025% trypan blue to stain the anterior capsule during cataract phacoemulsification surgery. Copious irrigation was performed upon realization of incorrect dye use. Corneal edema and iris discoloration developed during the early postoperative period and persisted at 24-months follow-up. However, keratoplasty was not required. The intracameral use of 1% methylene blue has a cytotoxic effect on the corneal endothelium and iris epithelium. Copious irrigation for at least 30 min using an anterior chamber maintainer may improve outcomes.

    Full Text Available Hyperthyroidism is one of the most common causes of cardiac failure. Blood volume expands greatly during pregnancy, especially after the last part of the second trimester. Such expansion exacerbates the symptoms of heart failure and accelerates the development of pulmonary edema when abnormal thyroid function is not well controlled. Two cases of pregnancy complicated with congestive heart failure and pulmonary edema due to hyperthyroidism are reported here. Both patients did not receive treatment for hyperthyroidism during pregnancy, and both sought clinical help during the third trimester. The clinical problems were resolved by medical management before delivery.

    There has recently been an expansion in the use of bilateral salpingectomy at the time of sterilization to theoretically decrease ovarian cancer risk. We sought to determine if postpartum salpingectomy is equivalent to postpartum bilateral tubal ligation (BTL) in terms of duration, estimated blood loss (EBL), and complication rate. A retrospective case series (Canadian Task Force Classification II-2). An academic inner-city hospital. All patients admitted for delivery of full-term intrauterine pregnancy desiring permanent sterilization between March 2014 and March 2015 were included. Excluded patients included those who had sterilization at the time of the cesarean section or other surgical procedure. Two cohorts were identified, those who had a planned postpartum tubal ligation and those having a postpartum salpingectomy. Postpartum sterilization. Researchers of this study recorded demographics, medical histories, and abdominal surgical histories for all patients who met the inclusion criteria. Surgical times, EBL, and complication rates were reviewed. Unpaired t test calculations were used to identify differences between age, body mass index, parity, and surgical time between the 2 cohorts. Chi-square tests were used to determine the statistical significance between complication rates, history of abdominal surgery, and past medical history of tubal disease between the 2 cohorts. Eighty women were identified, 64 in the BTL group and 16 in the salpingectomy cohort. The demographics of each cohort were equivocal. The average surgical time was 59.13 and 71.44 minutes in the BTL and salpingectomy cohorts, respectively. Of the 80 patients, only 1 had an EBL greater than 50 mL; this patient was in the BTL group. Four complications were noted in the BTL cohort, but none were evident in the salpingectomy group. There were no documented sterilization failures in the follow-up period (median = 9 months). Postpartum salpingectomy is slightly longer in duration but with

    Sodium magnetic resonance imaging is being used to study pulmonary edema in rats. Alloxan is used to induce permeability edema, and a saline infusion to induce hydrostatic edema. Images are made before and after edema is induced and after an infusion of varying doses of dextran-magnetite (1-5 mL) of different particle sizes and coating (charged or uncharged). The dextran-magnetite reduces signal intensity in the heart, liver, and lungs by differing amounts. The amount that enters the extravascular space of the lung should be a function of the type of edema and dextranmagnetite parameters and may enable one to distinguish the type of edema

    Diffuse alveolar hemorrhage (DAH) with negative-pressure pulmonary edema (NPPE) is an uncommon yet life-threatening condition. We aimed at describing the circumstances, clinical, radiological, and bronchoscopic features, as well as the outcome of patients with NPPE-related DAH. We performed a retrospective, observational cohort study, using data prospectively collected over 35 years in an intensive care unit (ICU). Of the 149 patients admitted for DAH, we identified 18 NPPE episodes in 15 patients, one admitted four times for recurrent NPPE-related DAH. The patients were primarily young, male, and athletic. The NPPE setting was postoperative (n = 12/18, 67%) or following generalized tonic-clonic seizures (n = 6/18, 33%). Hemoptysis was almost constant (n = 17/18, 94%), yet rarely massive (>200 cc, n = 1/18, 6%), with anemia observed in 10 (56%) episodes. The DAH triad (hemoptysis, anemia, and pulmonary infiltrates) was observed in 50% of episodes (n = 9/18), and acute respiratory failure in 94% (n = 17/18). Chest computed tomography revealed diffuse bilateral ground glass opacities (n = 10/10, 100%), while bronchoscopy detected bilateral hemorrhage (n = 12/12, 100%) and macroscopically bloody bronchoalveolar lavage, with siderophage absence in most (n = 7/8, 88%), indicating acute DAH. While one episode proved fatal, the other 17 recovered rapidly, with a mean ICU stay lasting 4.6 (2-15) days. Typically, the evolution was rapidly favorable under supportive care. NPPE-related DAH is a rare life-threatening condition occurring primarily after tonic-clonic generalized seizure or generalized anesthesia. Clinical circumstances are a key to its diagnosis. Early diagnosis and recognition likely allow for successful management of this potentially serious complication, whereas ictal-DAH appears ominous in epileptic patients.

    Full Text Available We report a 48-year-old female patient who presented to the emergency room with right eyelid edema, with 3 days of evolution. She had suffered minor trauma to this eye one week before. She reported episodes of right eyelid swelling of spontaneous resolution since the occurrence of a traumatic brain injury 5 years ago. Ophthalmological examination showed a soft and painless eyelid edema of the right eye. Brain computed tomography showed an area of bone discontinuity of the orbital roof with brain herniation and a CSF leak into the eyelid (blepharocele. Magnetic resonance confirmed the result of TC and revealed an area of frontal encephalomalacia. Ibuprofen (800 mg/day was prescribed, with complete resolution within 20 days. She was evaluated by Neurosurgery with no indication of surgery due to the resolution of the edema and absence of symptoms. Blepharocele is a rare entity that should be considered in the differential diagnosis of unilateral eyelid edema. It can be secondary to an orbital fracture or congenital lesion.

    2013-06-01

    Neurogenic pulmonary edema (NPE) is an acute life-threatening complication associated with many forms of central nervous system injury. NPE usually appears within minutes to hours after injury and has a high mortality rate if not recognized and treated appropriately. Lung ultrasound quickly provides at the bedside relevant information on the state of aeration and ventilation of the lung. We describe a case report of acute respiratory insufficiency after posterior cranial fossa surgery. The patient underwent a subtotal meningiomectomy. Postoperative course was complicated by respiratory failure with unstable hemodynamic parameters. The pulmonary edema was suspected, and sonography examination was performed. Lung ultrasound showed typical signs for non-cardiogenic pulmonary edema. Transthoracic echocardiography showed preserved left ventricle systolic function, but signs of the severe hypovolemia were found. We corrected for the preload and ventilator support settings. Within 24 h, her respiratory status improved with a resolution of the pulmonary edema. Lung ultrasound at the bedside can provide accurate information on lung status in neurocritically ill patients with acute respiratory failure. The addition of transthoracic echocardiography to lung sonography provides an additive insight on the eventual pulmonary involvement. Lung ultrasound has the potential to become a reference tool for bedside dynamic respiratory monitoring in the Neuro ICU.

    The aim of this study was to compare periorbital edema and ecchymosis seen after closed (endonasal) and open (external) septorhinoplasty (SRP). In total, 50 patients undergoing hump extraction and osteotomies were allocated to 2 groups. Group 1 consisted of 25 patients who underwent closed SRP. Group 2 consisted of 25 patients who underwent open SRP. Operation time, amount of intraoperative bleeding, and complications were recorded. Scoring of eyelid edema and periorbital ecchymosis was evaluated on the first, third, and seventh postoperative days using a scale of 0 to 4 by the first author. There was no statistically significant difference between the groups in terms of age, sex, or operation time. No significant difference was observed clinically or statistically in the scores of periorbital edema or ecchymosis between groups 1 and 2 on the first, third, and seventh postoperative days (P > 0.05). The authors observed no clinically or statistically significant difference in comparing periorbital edema and ecchymosis seen after closed and open SRP.

    Full Text Available La altura constituye un fascinante laboratorio natural para la investigación médica. Si bien al principio el objetivo de la investigación en la altura fue la comprensión de los mecanismos de adaptación del organismo a la hipoxia y la búsqueda de tratamientos para las enfermedades relacionadas con la altura, durante la última década el alcance de esta investigación se ha ampliado considerablemente. Dos importantes observaciones han generado las bases para el crecimiento del alcance científico de la investigación en la altura. Primero, el hecho de que el edema pulmonar agudo de la altura constituye un modelo único para estudiar los mecanismos fundamentales de la hipertensión pulmonar y el edema pulmonar en humanos. Segundo, que la hipoxia ambiental asociada con la exposición a la altura facilita la detección de disfunción vascular pulmonar y sistémica en un estadio precoz. Aquí revisaremos los estudios que, capitalizando estas observaciones, han llevado a la descripción de nuevos mecanismos subyacentes del edema pulmonar y de la hipertensión pulmonar, y a la primera demostración directa de la existencia de una programación fetal sobre la disfunción vascular en humanos.

    Functional and molecular changes associated with pathophysiological conditions are relatively easily detected based on tissue samples collected from patients. Population specific cellular responses to disease might remain undiscovered in samples taken from organs formed by a multitude of cell types. This is particularly apparent in the human cerebral cortex composed of a yet undefined number of neuron types with a potentially different involvement in disease processes. We combined cellular electrophysiology, anatomy and single cell digital PCR in human neurons identified in situ for the first time to assess mRNA expression and corresponding functional changes in response to edema and increased intracranial pressure. In single pyramidal cells, mRNA copy numbers of AQP1, AQP3, HMOX1, KCNN4, SCN3B and SOD2 increased, while CACNA1B, CRH decreased in edema. In addition, single pyramidal cells increased the copy number of AQP1, HTR5A and KCNS1 mRNAs in response to increased intracranial pressure. In contrast to pyramidal cells, AQP1, HMOX1and KCNN4 remained unchanged in single cell digital PCR performed on fast spiking cells in edema. Corroborating single cell digital PCR results, pharmacological and immunohistochemical results also suggested the presence of KCNN4 encoding the α-subunit of KCa3.1 channels in edema on pyramidal cells, but not on interneurons. We measured the frequency of spontaneous EPSPs on pyramidal cells in both pathophysiological conditions and on fast spiking interneurons in edema and found a significant decrease in each case, which was accompanied by an increase in input resistances on both cell types and by a drop in dendritic spine density on pyramidal cells consistent with a loss of excitatory synapses. Our results identify anatomical and/or physiological changes in human pyramidal and fast spiking cells in edema and increased intracranial pressure revealing cell type specific quantitative changes in gene expression.

    Indirect radionuclide lymphoscintigraphy is a safe, non-invasive and physiological method for the assessment of the limb lymphatic system. Colloids as antimony or rhenium sulphide labeled with 99m technetium have been widely used for morphological studies. Quantitative studies involving a continuous count rate monitoring of the injection sites followed by a computer analysis of dynamic image sequences have been a new promising step for an objective measurement of the peripheral lymphatic function. The injection site is always bilateral on the first web space of either the hand or the foot using a small volume (<0.2 mL) of the radiocolloid. This method has been validated on 30 young healthy volunteers and normal values established from a group of 125 upper and 141 lower limbs (normal subjects). The normal results showed a slight but continuous decrease in lymphatic function depending on the age of the subject. In pathological situations, we observed dysfunction of the lymphatic system in pure lymphoedemas or so-called lympho-venous edemas as demonstrated on the 1,182 upper and 2,463 lower limbs tested. The radionuclide lymphoscintigraphy may be helpful in cases of unilateral swollen limbs demonstrating a lymphatic dysfunction on a clinically normal contralateral limb at the first stage of a distal edema which appears within a few weeks or days, in a transient edema phase when normal status and oedema alternate. The lymphoscintigraphy gives objective and reproducible parameters necessary to assess the lymphatic variation under therapy (decongestive physiotherapy, surgery, drugs) and may be useful in the selection of new lympho-tonic treatments. This method is only reflecting the lymphatic function and is unable to appreciate the total lymphatic flow of the limb. Its results only reflect what happens at the injection site and it may be necessary to add a second test using a proximal injection in order to assess the occurrence of lymph nodes not visualized by the

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. © 2016 The authors.

    The aim of the study was to investigate whether children with bilateral conductive hearing loss benefit from their second device (i.e., the bilateral bone conduction device [BCD]). Speech recognition in noise was assessed in 10 children fitted with bilateral BCDs during childhood. Speech recognition was measured in 2 conditions with both BCDs active. Spatial resolution was tested with the Minimum Audible Angle test in the bilateral and monaural listening conditions. Children demonstrated an improvement in speech recognition when speech was presented from the front and noise was presented from the right-hand side as compared with both speech and noise being presented from the front. The minimum audible angle decreased from 57° in the best monaural condition to 13° in the bilateral condition. The audiological outcomes demonstrate the advantage of bilateral BCD fitting in children with bilateral conductive hearing loss.

    Unilateral and bilateral sudden sensorineural hearing loss represent different disease entities. The unilateral condition is more common and predominantly idiopathic, and up to 65 per cent of patients spontaneously recover hearing. Conversely, the bilateral condition is rare, mostly associated with serious systemic conditions, and has a higher prevalence of morbidity and mortality. A literature search using the PubMed database was conducted using the MeSH terms 'sudden', 'bilateral' and 'sensorineural hearing loss'. One hundred and three reported cases of bilateral sudden sensorineural hearing loss were identified. The condition is most often associated with toxic, autoimmune, neoplastic and vascular conditions. A younger age of onset, with a bimodal age distribution, was seen for bilateral sudden sensorineural hearing loss, compared with the unilateral condition. Patients with the bilateral condition had more profound hearing loss, with poorer recovery and a 35 per cent mortality rate. Vestibular symptoms were also less common than in the unilateral condition. The presentation of bilateral sudden onset sensorineural hearing loss is a medical emergency requiring thorough and urgent investigation to exclude life-threatening and reversible conditions.

    Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

    intratorácica ocasionado por la obstrucción de las vías aéreas superiores. Se describió el caso de paciente saludable, sometida a la anestesia general, que presentó edema agudo pulmonar después de la extubación traqueal. RELATO DEL CASO: Paciente de 23 años, sexo femenino, estado físico ASA II, sometida a la anestesia general para videolaparoscopía ginecológica. El procedimiento duró 3 horas, sin intercurrencias. Después de la extubación, la paciente presentó laringoespasmo y disminución de la saturación de oxígeno. Hubo una mejoría después de la colocación de la cánula oral y administración de oxígeno bajo presión positiva, con máscara facial. Estabilizado el cuadro, se la llevó a la sala de recuperación postanestésica, en donde, en cuanto entró, presentó edema agudo de pulmón con eliminación de secreción sero-sanguinolenta. El tratamiento constó de elevación del dorso, oxígeno bajo máscara, furosemida y restricción hídrica. La radiografía torácica mostró una imagen compatible con edema agudo pulmonar y área cardíaca normal. El electrocardiograma (ECG, ecocardiografía y enzimas cardíacas estaban normales. La paciente presentó una buena evolución, recibiendo alta hospitalaria al día siguiente, sin síntomas. CONCLUSIONES: El edema agudo de pulmón asociado a la obstrucción de las vías aéreas superiores es una condición clínica que puede agravar los procedimientos quirúrgicos de baja morbidez y que aparece principalmente en pacientes jóvenes. El tratamiento debe ser empezado rápidamente, pues la resolución también es rápida y en la mayoría de las veces, no quedan secuelas.BAKGROUND AND OBJECTIVES: Negative pressure pulmonary edema has been defined as non-cardiogenic edema, with transudation of fluid to the interstitial space of the lungs due to an increase in negative intrathoracic pressure secondary to obstruction of the upper airways.

    Andressa Alves da Silva

    Full Text Available Leptospirosis is a zoonosis of worldwide occurrence caused by the spirochete Leptospira interrogans. It is an acute feverish disease with a broad clinical spectrum and follows a characteristic biphasic course. Bilateral facial palsy is a rare clinical condition and the differential diagnosis of its causes is extensive. The objective of this exploratory study, presented as a case report, is to describe the occurrence of bilateral facial palsy as an unusual manifestation of leptospirosis. This suggestion should not be overlooked when analyzing the causes for bilateral facial palsy, and should be considered with other possible differential diagnoses, some of which are potentially fatal.

    Full Text Available Bilateral tubal pregnancy is very rare and occurs in only 1 out of every 200,000 spontaneous pregnancies. In this case, a 29-year-old woman with a history of primary infertility underwent treatment with human menopausal gonadotropin (hMG-human chorionic gonadotropin (hCG, and became pregnant. A gestational sac (GS was not detected in the uterus and transvaginal ultrasonography (USG revealed GS with fetal heartbeat in the left adnexa at 7 weeks and 6 days of gestation. The patient underwent laparoscopic surgery and ultimately, bilateral tubal pregnancy was diagnosed. Consequently, bilateral fallopian tube resection was performed. Afterwards, she conceived by assisted reproductive technology (ART and delivered vaginally. This case suggests that even if a GS is found in one fallopian tube by USG, it is important to evaluate the other fallopian tube carefully.

    2015-06-01

    Full Text Available The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we introduce a way to control the tonal weighting coefficients, the flowing bilateral filter, reducing "halo" artifacts typically produced by the regular bilateral filter around a large peak surrounded by two valleys of lower values. In this paper we propose to investigate exact and approximated versions of CPU and parallel GPU (Graphical Processing Unit based implementations of the regular and flowing bilateral filter using the NVidia CUDA API. Fast implementations of these filters are important for the processing of large 3D volumes up to several GB acquired by x-ray or electron tomography.

    Full Text Available Spontaneous bilateral ectopic gestation is very rare. The authors report a case diagnosed and taken care of at Yalgado Ouedraogo Teaching Hospital, Ouagadougou. It was a 30-year-old patient with no known pathological history. She had presented at the obstetric emergencies with a state of hypovolemic shock by haemoperitoneum with digestive disorders, pelvic pain, vaginal bleeding, and a mention of delayed menstruation. The ultrasound coupled with the urinary immunological pregnancy test confirmed the diagnosis of ruptured ectopic pregnancy and a bilateral form was suspected. A laparotomy in emergency confirmed the diagnosis of bilateral ectopic gestation with a right ampullary unruptured pregnancy and a left isthmic ruptured gestation. A bilateral salpingectomy was performed and counseling was made for the use of medical help of procreation in case of future need of pregnancy.

    The purpose of this study was to evaluate the bilateral coordination in children and adolescents with visual impairments aged 7 to 18 years in comparison to their sighted peers. An additional objective was to identify the influence of sex and age on bilateral coordination. Seventy-five individuals with congenital severe visual impairment (40 girls and 35 boys) comprised the visually impaired group. The Sighted group comprised 139 youth without visual impairment. Subtest 4 of the Bruininks-Oseretsky Test of Motor Proficiency was administered to test bilateral coordination. To analyze the effect of the independent variables in the results obtained in the Subtest 4, four linear regression models were applied according to group and sex. The results indicated that severe visual impairment and lack of visual sensation had a negative effect on the development of participants' bilateral coordination, which however did not depend on sex or age. © The Author(s) 2016.

    To present a case of a patient with simultaneous bilateral retinal detachments treated successfully with bilateral pneumatic retinopexy. Case report. This is a case of an otherwise healthy 49-year-old woman with no remarkable ocular history that presented with simultaneous phakic superior bilateral rhegmatogenous retinal detachments. Treatment on the day of presentation included laser retinopexy of the inferior lattice degeneration in the left eye and bilateral intravitreal injection of 0.4 cc of 100% C3F8 gas preceded by topical anesthesia. After 48 hours, both retinas were completely reattached, and bilateral laser retinopexy was performed to the superior tears. After a review of the literature, the authors could find only two reported cases of simultaneous bilateral retinal detachments treated successfully with pneumatic retinopexy. This is not only a cost-effective procedure but also allows treatment when there is no immediate operating room availability or a when a quick referral for surgery is not possible.

    Purpose: To determine whether patients with early-stage bilateral breast cancer can be treated with definitive irradiation following breast-conserving surgery with acceptable survival, local control, complications, and cosmesis. Methods and Materials: During the period 1977-1992, 55 women with Stage 0, I, or II concurrent (n = 12) or sequential (n = 43) bilateral breast cancer were treated with definitive irradiation following breast-conserving surgery. The records of these 55 patients with 110 treated breasts were reviewed for tumor size, histology, pathologic axillary lymph node status, first and overall site(s) of failure, and adjuvant chemotherapy or hormonal therapy. Curves for survival, local control, and regional control were determined. Cosmetic outcome, complication rates, and matching technique were analyzed. The median total radiation dose delivered was 64 Gy (range 42-72) using tangential whole-breast irradiation followed by an electron or iridium implant boost. The tangential fields were matched with no overlap in 40 patients (73%); there was overlap on skin of up to 4 cm in 14 patients (25%); and the matching technique was unknown in 1 patient (2%). The median follow-up for the 12 women with concurrent bilateral breast cancer was 4.0 years. The median follow-up for the other 43 women with sequential cancer was 9.3 and 4.9 years, respectively, after the first and second cancers. Results: For the overall group of 55 patients, the 5- and 10-year overall survival rates were 96% and 94%, respectively, after treatment of the first cancer, and 96% and 92%, respectively, after treatment of the second cancer. The 5- and 10-year actuarial relapse-free survival rates were 90% and 75%, respectively, after treatment of the first cancer, and 83% and 72%, respectively, after treatment of the second cancer. For the 110 treated breast cancers, the 5- and 10-year actuarial local failure rates were 5% and 15%, respectively. Complication rates were: 28% breast edema, 8

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

    Full Text Available We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 µm in the right eye and of 710 µm in the left eye, as well as an average paracentral pachymetry of 436 and 270 µm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus.

    Organophosphorus exposure affects different organs such as skeletal muscles, the gastrointestinal tract, liver, lung, and brain. The present experiment aimed to evaluate the effect of escin on cerebral edema induced by acute omethoate poisoning. Sprague-Dawley rats were administered subcutaneously with omethoate at a single dose of 60 mg/kg followed by escin treatment. The results showed that escin reduced the brain water content and the amount of Evans blue in omethoate-poisoned animals. Treatment with escin decreased the levels of tumor necrosis factor-alpha (TNF-α), matrix metalloproteinase-9 (MMP-9), cyclooxygenase-2 (COX-2), and prostaglandin E₂ (PGE₂) in the brain. Escin also alleviated the histopathological change induced by acute omethoate poisoning. The findings demonstrated that escin can attenuate cerebral edema induced by acute omethoate poisoning, and the underlying mechanism was associated with ameliorating the permeability of the blood-brain barrier.

    2006-05-01

    Full Text Available Massive ovarian edema (MOE is a rare entity characterized by an accumulation of stromal edema fluid and occurs primarily in young women. The etiology is not clear, but is suspected to be the result of partial torsion of the ovary. After the establishment of a correct diagnosis, organ-sparing surgical treatment is the standard treatment. With the assistance of laparoscopy, we diagnosed and managed MOE in a 26-year-old woman who had a 4-year history of primary infertility and intermittent lower abdominal pain that had lasted for more than 6 months. With de-torsion, wedge resection, and plication of the ovary, the patient was successfully relieved of the abdominal pain and experienced no recurrence in the follow-up period. A later spontaneous pregnancy demonstrated the practicality of this conservative treatment.

    The purpose of this study was to examine the frequency of muscle edema and the diagnostic usefulness of Gd-DTPA in neuromuscular diseases. 144 consecutive patients with various generalized neuromuscular diseases were examined by MR imaging. Areas of high signal intensity, relative to normal muscle, were seen in 36% of T2-weighted images, whereas the corresponding T1-weighted images showed normal or lower signal intensities. These edema-like abnormalities -enlargement of the extracellular fluid space-were found more often in inflammatory and metabolic myopathies, but were also seen in degenerative myopathies. Contrast-enhanced T1-weighted images in 25 patients were not more sensitive than plain T2-weighted images. (orig.)

    Full Text Available Purpose: To describe optical coherence tomography (OCT findings in a patient with Berlin′s edema following blunt ocular trauma. Case Report: A 26-year-old man presented with acute loss of vision in his left eye following blunt trauma. He underwent a complete ophthalmologic examination and OCT. Fundus examination revealed abnormal yellow discoloration in the macula. OCT disclosed thickening of outer retinal structures and increased reflectivity in the area of photoreceptor outer segments with preservation of inner retinal architecture. Re-examination was conducted one month later at the time which OCT changes resolved leading to a surprisingly normal appearance. Conclusion: OCT can be a useful tool in the diagnosis and follow-up of eyes with Berlin′s edema and may reveal ultrastructural macular changes.

    Recently, we characterized a Gamma Knife® radiation necrosis mouse model with various magnetic resonance imaging (MRI) protocols to identify biomarkers useful in differentiation from tumors. Though the irradiation was focal to one hemisphere, a contralateral injury was observed that appeared to be localized in the white matter only. Interestingly, this injury was identifiable in T2-weighted images, apparent diffusion coefficient (ADC), and magnetization transfer ratio (MTR) maps, but not on post-contrast T1-weighted images. This observation of edema independent of vascular changes is akin to the perilesional edema seen in clinical radiation necrosis. The pathology underlying the observed white-matter MRI changes was explored by performing immunohistochemistry for healthy axons and myelin. The presence of both healthy axons and myelin was reduced in the contralateral white-matter lesion. Based on our immunohistochemical findings, the contralateral white-matter injury is most likely due to axonal degeneration

    To assess the value of positional shifting to a gravity-dependent area, as revealed by HRCT, in differentiating pulmonary edema (PE) from other conditions. Sixteen consecutive patients in whom plain radiographs suggested the presence of pulmonary edema but the clinical findings were indefinite underwent HRCT of the lung. For initial scanning they were in the supine position, and then in the prone position. Findings of ground-glass opacity, interlobular septal thickening and peribronchovascular interistitial thickening were analyzed in terms of the presence and degree of shifting to a gravity-dependent area, a grade of high, intermediate or low being assigned. PE was diagnosed in 8 of 16 cases, the remainder being designated as non-pulmonary edema (NPE). Ground-glass opacity was observed in all 16, while the degree of positional shifting was found to be high in ten (PE:NPE=6:4), intermediate in four (PE:NPE=2:2), and low in two (PE:NPE=0:2). There was no significant difference between the two groups (ρ > 0.05). Interlobular septal thickening was observed in all but two NPE cases; the degree of shifting was high in six (PE:NPE=6:0), intermediate in one (PE), and low in seven (PE:NPE=1:6). Shifting was significantly more prominent in PE than in NPE case (ρ <0.05). Peribronchovascular interstitial thickening was positive in all PE cases and one NPE case, with no positional shifting. Positional shifting of interlobular septal thickening to a gravity-dependent area, as demonstrated by HRCT, is the most specific indicator of pulmonary edema

    Assessing the pathology of the synovium, its thickening and increased vascularity through ultrasound and magnetic resonance examinations (more often an ultrasound study alone) is still considered a sensitive parameter in the diagnosis of rheumatoid arthritis and in monitoring of treatment efficacy. Magnetic resonance studies showed that, aside from the joint pannus, the subchondral bone tissue constitutes an essential element in the development of rheumatoid arthritis. Bone marrow edema correlates with inflammation severity, joint destruction, clinical signs and symptoms of rheumatoid arthritis, and thus is considered a predictor of rapid radiological progression of the disease. The newest studies reveal that bone marrow edema may be a more sensitive indicator of the response to therapy than appearance of the synovium. Bone marrow edema presents with increased signal in T2-weighted images, being most visible in fat saturation or IR sequences (STIR, TIRM). On the other hand, it is hypointense and less evident in T1-weighted images. It becomes enhanced (hyperintense) after contrast administration. Histopathological studies confirmed that it is a result of bone inflammation (osteitis/osteomyelitis), i.e. replacememt of bone marrow fat by inflammatory infiltrates containing macrophages, T lymphocytes, B lymphocytes, plasma cells and osteoclasts. Bone marrow edema appears after a few weeks from occurrence of symptoms and therefore is considered an early marker of inflammation. It correlates with clinical assessment of disease activity and elevated markers of acute inflammatory phase, i.e. ESR and CRP. It is a reversible phenomenon and may become attenuated due to biological treatment. It is considered a “herald” of erosions, as the risk of their formation is 6-fold higher in sites where BME was previously noted

In the present study, we investigated the efficacy and safety of a new betamethasone valerate medicated plaster (Betesil® to manage facial swelling, edema, inflammation, ecchymosis, and hematoma, when applied immediately after a facial rejuvenation procedure.Materials and methods: We applied the plaster to the skin of 20 healthy patients for 12 hours immediately after hyaluronic acid-based procedure performed with the aim of erasing facial wrinkles of perioral and nasolabial folds and improving chin and eye contour. A further 20 patients underwent the same cosmetic procedure, but they were treated with an aescin 10% cream (applied immediately after the procedure, in the evening, and the morning after and served as control group.Results: Betesil® application resulted in a significant improvement in swelling/edema/inflammation score, if compared with aescin 10% cream (P < 0.01. As for facial ecchymosis and hematoma around the needle injection track, only two patients in the active treatment group displayed minimal ecchymosis and hematoma. In the control group, two patients presented minimal ecchymosis and three slight hematoma. However, using the ecchymosis/hematoma score, no significant difference between Betesil® and aescin 10% cream groups was observed. Patients’ satisfaction was significantly higher among subjects receiving Betesil®, if compared to patients receiving aescin 10% cream (P < 0.01.Conclusion: The present study supports the use of Betesil® plaster immediately after facial cosmetic procedures in order

    Full Text Available In bilateral thumb amputations, the functional impairment is serious and every attempt should be made to reconstruct the thumb. We report a case of bilateral post traumatic thumb amputation, reconstructed with bilateral second toe transfer. Only two such cases have been reported in literature so far. Though there are various modalities for the reconstruction of thumb, microvascular toe transfer has its own merits. The convalescent period is minimal with excellent function. It is bilaterally symmetric and aesthetically superior to the osteoplastic reconstruction. The technical details are discussed, and the long term functional and aesthetic results are presented.

  10. Management of upper airway edema caused by hereditary angioedema

    Directory of Open Access Journals (Sweden)

    Farkas Henriette

    2010-07-01

    Full Text Available Abstract Hereditary angioedema is a rare disorder with a genetic background involving mutations in the genes encoding C1-INH and of factor XII. Its etiology is unknown in a proportion of cases. Recurrent edema formation may involve the subcutis and the submucosa - the latter can produce obstruction in the upper airways and thereby lead to life-threatening asphyxia. This is the reason for the high, 30-to 50-per-cent mortality of undiagnosed or improperly managed cases. Airway obstruction can be prevented through early diagnosis, meaningful patient information, timely recognition of initial symptoms, state-of-the-art emergency therapy, and close monitoring of the patient. Prophylaxis can substantially mitigate the risk of upper airway edema and also improve the patients' quality of life. Notwithstanding the foregoing, any form of upper airway edema should be regarded as a potentially life-threatening condition. None of the currently available prophylactic modalities is capable of preventing UAE with absolute certainty.

    Sánchez Marteles, Marta; Urrutia, Agustín

    2014-03-01

    Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index 30 mmHg) and absent or reduced diuresis (acute myocardial infarction. Treatment consists of general measures to reverse acidosis and hypoxemia, as well as the use of vasopressors and inotropic drugs. Early coronary revascularization has been demonstrated to improve survival in shock associated with ischaemic heart disease. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    In acute cerebral ischemia, the assessment of irreversible injury is crucial for treatment decisions and the patient's prognosis. There is still uncertainty how imaging can safely differentiate reversible from irreversible ischemic brain tissue in the acute phase of stroke. We have searched PubMed and Google Scholar for experimental and clinical papers describing the pathology and pathophysiology of cerebral ischemia under controlled conditions. Within the first 6 h of stroke onset, ischemic cell injury is subtle and hard to recognize under the microscope. Functional impairment is obvious, but can be induced by ischemic blood flow allowing recovery with flow restoration. The critical cerebral blood flow (CBF) threshold for irreversible injury is ∝15 ml/100 g x min. Below this threshold, ischemic brain tissue takes up water in case of any residual capillary flow (ionic edema). Because tissue water content is linearly related to X-ray attenuation, computed tomography (CT) can detect and measure ionic edema and, thus, determine ischemic brain infarction. In contrast, diffusion-weighted magnetic resonance imaging (DWI) detects cytotoxic edema that develops at higher thresholds of ischemic CBF and is thus highly sensitive for milder levels of brain ischemia, but not specific for irreversible brain tissue injury. CT and MRI are complimentary in the detection of ischemic stroke pathology and are valuable for treatment decisions. (orig.)

We have searched PubMed and Google Scholar for experimental and clinical papers describing the pathology and pathophysiology of cerebral ischemia under controlled conditions. Within the first 6 h of stroke onset, ischemic cell injury is subtle and hard to recognize under the microscope. Functional impairment is obvious, but can be induced by ischemic blood flow allowing recovery with flow restoration. The critical cerebral blood flow (CBF) threshold for irreversible injury is ∝15 ml/100 g x min. Below this threshold, ischemic brain tissue takes up water in case of any residual capillary flow (ionic edema). Because tissue water content is linearly related to X-ray attenuation, computed tomography (CT) can detect and measure ionic edema and, thus, determine ischemic brain infarction. In contrast, diffusion-weighted magnetic resonance imaging (DWI) detects cytotoxic edema that develops at higher thresholds of ischemic CBF and is thus highly sensitive for milder levels of brain ischemia, but not specific for irreversible brain tissue injury. CT and MRI are complimentary in the detection of ischemic stroke pathology and are valuable for treatment decisions. (orig.)

    To evaluate the CT findings and clinical significance of colonic edema in liver cirrhosis. We retrospectively reviewed the CT scans of 221 cases of clinically diagnosed liver cirrhosis in 173 patients. In 30 of these [23 men and six women aged between 35 and 67(mean, 54) years], colonic edema was present. We evaluated its distribution (ascending, transverse or descending colon), analysed serum albumin and bilirubin levels, and in both the colonic edema and non-colonic edema group, determined whether ascites was present. Thus, we sought correlation between the presence of colonic edema, the severity of liver cirrhosis, and each parameter. CT revealed colonic edema in 30 of 221 cases(14%). Of the 30, 13 cases(43%) were diffuse colonic edema and 17(57%) were regional edema. Among these 17 cases, 12(71%) were seen only in the ascending colon, while five(29%) were seen in both the ascending and transverse colon. In the group with colonic edema, the mean level of serum albumin was 2.6g/dl, and that of serum bilirubin was 4.9mg/dl ; 20 patients(67%) had ascites. In the group without colonic edema, mean levels of serum albumin and serum bilirubin were 3.0g/dl and 4.1mg/dl, respectively ; 43 patients(30%) had ascites. There was no significant statistical difference in serum albumin and bilirubin levels between the colonic edema and non-colonic edema group(p>0.05), though ascites was more common among the former group. In cases of liver cirrhosis, CT evidence of colonic edema is not uncommon. The ascending colon is most frequently involved, though disease severity does not vary significantly according to site. When CT reveals the presence of colonic edema, further diagnostic evaluation is not necessary if there is no evidence of clinical symptoms

    11 C-methylated inulin, supposedly useful for imaging of brain edema and pulmonary edema, was prepared using cyclotron produced 11 CO 2 . The synthesis consists of the production of 11 C-methyl iodide and its coupling with inulin alkoxide sodium in dimethylsulfoxide as solvent. 11 C labeled inulin was purified by alcohol precipitation. The radiochemical yield of pure 11 C-inulin was 34% of 11 CO 2 30 min after the end of bombardment. The blood clearance and body distribution of 11 C was observed in rabbits after i.v. injection of 11 C-inulin. The blood clearance curve was composed of a sum of three exponential functions. The gamma camera image showed that the 11 C activity in blood moved quickly to kidneys and urine and a small dose of radioactivity remained persistently in edematous tissues, i.e. the edematous lung tissues produced by oleic acid treatment.

    Full Text Available According to the National Hip Fracture Database, over 64,000 patients were admitted with a hip fracture across England, Wales, and Northern Ireland in 2013, but very few are bilateral, and there are no current cases in the literature of bilateral neck of femur fractures in a patient with bilateral below-knee amputations. We present a case of a 69-year-old bilateral below-knee amputee male admitted to the emergency department with bilateral hip pain and radiological evidence of bilateral displaced neck of femur fractures. The patient subsequently underwent synchronous bilateral total hip replacements under general anaesthetic and an epidural and then went on to make a full recovery. He was discharged 27 days after arrival in hospital. Outpatient follow-up at 3 months has shown that the patient has returned to a similar level of preinjury function and is still able to carry out his daily activities with walking aids and bilateral leg prostheses.

    To assess bilateral breast cancer patients, initially diagnosed with stage II unilateral breast cancer. 113 patients with stage 0-II breast cancer diagnosed between 1983 and 2011 were assessed. Of these, 8 patients had bilateral breast cancer: 7 patients with metachronous bilateral breast cancer and 1 patient with synchronous breast cancer. Breast ultrasound, mammography, computed tomography and magnetic resonance imaging were used to diagnose recurrence, loco regional and distant metastasis. Age at diagnosis ranged from 37 to 59 years, with a maximum age incidence in the 4th decade (age between: 31-40 years). The average time interval between the two breast cancers was 8.125 years. The most common histological type was invasive ductal carcinoma. All eight patients with bilateral breast cancer had at least one type of recurrence/metastasis, mostly in the liver, and statistically the pleuropulmonary and liver metastases were the most frequent causes of death. Patients in the 4th decade diagnosed with unilateral breast cancer are at risk of developing bilateral breast cancer. In metachronous breast cancer, the time interval between the detection of the second breast cancer and death is directly proportional to the time interval between the two breast cancers.

    We conducted an evaluation of outcomes for microsurgical vasectomy reversal in which sperm are absent from the vas fluid in order to determine a threshold obstructive interval when vasoepididymostomy (VE) may be indicated. Vasectomy reversal was performed for 32 patients with intravasal azoospermia: 25 received bilateral vasovasostomy (VV), 1 had a bilateral VV, 5 underwent VV/VE, and 1 had bilateral VE. Overall, the patency rate was 50% (14 of 28). Five pregnancies (20%) and 3 live births (12%) occurred in 25 patients with sufficient follow-up. One pregnancy was electively terminated and the other is ongoing, for an ongoing or delivered rate of 16%. The patency rate for VV (either bilateral or unilateral) was 55% (12 of 22). Median obstructive interval was 7 years in patent and 15 years in nonpatent cases, respectively, (P =.0027). Sperm were not observed after VV in any case n which the obstructive interval was greater than 11 years. If VV was limited to obstructive intervals of 11 years or less, then the patency rate was 80% (12 of 15) and the pregnancy rate was 38% (5 of 13). The patency rate for bilateral VV was 67% (8 of 12) if clear fluid was observed on at least one side. We conclude that VE is not required in every case of intravasal azoospermia, but it could improve success rates in this setting. Based on our experience, VE may be indicated for intravasal azoospermia if the obstructive interval is more than 11 years.

    In Brazil electricity is traded through three segments: the spot market that balances offer and demand, with prices calculated by a cost-based computational model; the regulated market , where prices are settled in public auctions, and the free market for bilateral contracts. As spot and regulated market prices are public information, a seller is able to calculate his opportunity price to trade a bilateral contract in the free market by using the non-arbitrage principle. Thus, the seller searches the price of a bilateral contract in the free market that balances his/her revenues with the value expected in case it were negotiated in the regulated and the spot market. Besides the expected revenue, the seller may also consider the CVaR to measure the risk of her/his bilateral contract in the free market. So this paper develops a binomial lattice approach to price bilateral contracts in the free market, considering the seller's opportunity of negotiations in both regulated and spot markets, and measuring the contract risk directly.

    Bilateral anterior dislocation of the shoulders with fractures of both greater tuberosities is very rare. A 76-year-old woman sustained a bilateral anterior dislocation of her shoulders with fractures of the greater tuberosity on both sides after a fall on stairs. Her arms were abducted and externally rotated. Radiological examination revealed the bilateral anterior dislocation and also the bilateral fractures of the greater tuberosity. Prompt closed reduction followed by a 3 weeks immobilization and subsequent rehabilitation allows a good outcome. Results at one-year follow-up were satisfactory with normal range of motion and no redislocations occurring. To our knowledge, this is the first reported case of bilateral anterior shoulder dislocation associated with fractures of both greater tuberosities in elderly woman.

    To present the results of bilateral superior rectus transposition with medial rectus recession in a case of chronic bilateral sixth nerve palsy. Bilateral superior rectus transposition with medial rectus recession resulted in full correction of esotropia with resolution of horizontal diplopia, improvement in abduction, and regain of stereoacuity in our case. There was minimal limitation of adduction, with no abnormal vertical or torsional changes. Bilateral superior rectus transposition with medial rectus recession appears to be a useful procedure for surgical treatment of bilateral sixth nerve palsy with minimal side effects. Given its potential for reduced risk of anterior segment ischemia (ASI), it may have especially good value in the select group of patients at risk for ASI. Studies with larger sample size and longer follow up are needed to further evaluate this procedure and elucidate the variables in surgical technique for superior rectus transposition.

    A rare case of bilateral ventrolateral pontine infarction in a 70-year-old man who developed progressive dysarthria and bilateral sensory disturbance is reported with literature review. He had been diagnosed with hypertension, dyslipidemia, and impaired glucose tolerance 10 years earlier. Ten days before admission, he was aware of the difficulty in walking and speaking, which gradually worsened. On admission he showed bilateral thermal hypoalgesia of face and lower extremities, dysarthria, dysphagia, and ataxic gait. High resolution three-dimensional MRI revealed bilateral ventrolateral pontine infarction with a large atherosclerotic plaque in the ventral side of the basilar artery, which led to a diagnosis of atherothrombotic brain infarction. The atherosclerotic plaque in the basilar artery was thought to be responsible for simultaneous occlusion of the bilateral short circumflex arteries of the pons.

    Pulmonary edema associated with increased vascular permeability is a severe complication of Staphylococcus aureus-induced sepsis and an important cause of human pathology and death. We investigated the role of the mammalian acid sphingomyelinase (Asm)/ceramide system in the development of lung edema caused by S. aureus. Our findings demonstrate that genetic deficiency or pharmacologic inhibition of Asm reduced lung edema in mice infected with S. aureus. The Asm/ceramide system triggered the formation of superoxide, resulting in degradation of tight junction proteins followed by lung edema. Treatment of infected mice with amitriptyline, a potent inhibitor of Asm, protected mice from lung edema caused by S. aureus, but did not reduce systemic bacterial numbers. In turn, treatment with antibiotics reduced bacterial numbers but did not protect mice from lung edema. In contrast, only the combination of antibiotics and amitriptyline inhibited both pulmonary edema and bacteremia protecting mice from lethal sepsis and lung dysfunction suggesting the combination of both drugs as novel treatment option for sepsis. Antibiotics are often insufficient to cure S. aureus-induced sepsis. S. aureus induces lung edema via the Asm/ceramide system. Genetic deficiency of Asm inhibits lung dysfunction upon infection with S. aureus. Pharmacologic inhibition of Asm reduces lung edema induced by S. aureus. Antibiotics plus amitriptyline protect mice from lung edema and lethal S. aureus sepsis.

    Our previous studies have shown that female mice have less brain edema and better recovery in neurological deficits after intracerebral hemorrhage (ICH) and that 17β-estradiol treatment in male mice markedly reduces ICH-induced brain edema. In this study, we investigated the role of gender and the estrogen receptors (ERs) in iron-induced brain edema. There were three parts in this study: (1) either male or female mice received an injection of 10 μL FeCl2 (1 mM) into the right caudate; (2) females received an intracaudate injection of FeCl2 or saline with 1 μg of ICI 182,780 (antagonists of ERs) or vehicle; and (3) males were treated with the ER regulator tamoxifen (5 mg/kg subcutaneously) or vehicle 1 h after FeCl2 injection. Mice were euthanized 24 h later for brain edema determination. FeCl2 induced lower brain edema in females than in males. Co-injection of ICI 182,780 with FeCl2 aggravated iron-induced brain edema in female mice. ICI 182,780 itself did not induce brain edema at the dose of 1 μg. Tamoxifen treatment reduced FeCl2-induced brain edema in male mice. In conclusion, iron induced less brain edema in female mice than in males. ER modification can affect iron-induced brain edema.

    Breast-conserving surgery (BCS) is commonly used in breast cancer treatment. Despite its benefits, some women will be troubled by breast edema. Breast edema may cause an unsatisfactory cosmetic result, influencing the quality of life. The purpose of this systematic review is to investigate the incidence of breast edema and to identify risk factors of breast edema in breast cancer patients following BCS and radiotherapy. A systematic literature search was performed using different electronic databases (PubMed, Web of Science, Cochrane, Embase) until June 2014. Inclusion criteria were as follows: (1) research studies that included female breast cancer patients who were treated with BCS and radiotherapy and (2) studies that investigated the incidence of breast edema and/or risk factors of breast edema. Exclusion criteria were (1) reviews or case studies and (2) studies published before 1995. We identified in total 28 papers which represented 4,011 patients. There was a great variation in the incidence of breast edema (0-90.4 %). We identified several possible risk factors for breast edema namely increasing irradiated breast volume, increasing boost volume, the use of a photon boost, increasing breast separation, a higher density of the breast tissue, a large tumor, a higher specimen weight, postoperative infection, acute postoperative toxicity, and diabetes mellitus. However, their prognostic value remains uncertain. Breast edema is a common complaint after BCS and radiotherapy. A number of possible risk factors associated with breast edema were identified, but further research is warranted.

    To describe the excellent outcome of surgery for bilateral giant retinal tears (GRTs) with better options of endotamponade. This is a case report of a 62-year-old man who presented with bilateral GRTs and associated retinal detachment. The tear in the right eye was supero-temporal and silicone oil was used as an endotamponade. The tear in the left eye was infero-temporal and perfluorocarbon liquid was used as an endotamponade. The outcome at 6 months after surgery was excellent with visual acuities of 6/6 in both eyes. Improved availability of endotamponade agents allows repair of bilateral GRTs to be done at the same time, with good surgical outcomes.

    Reiter's syndrome is commonly associated with conjunctivitis and rarely with uveitis. Bilateral disciform keratitis at presentation is a very rare manifestation in Reiter's syndrome. A 13-year-old boy developed bilateral disciform keratitis with oligoarthritis following an episode of conjunctivitis. In addition he had suspected bacterial keratitis with hypopyon in the left eye as a possible secondary infection of an epithelial defect that is a feature of Reiter's keratitis. Empirical treatment with intensive topical antibiotics as a therapeutic trial completely resolved the hypopyon and the disciform keratitis settled with topical steroid treatment. The patient achieved a best corrected vision of 20/20 in both the eyes 6 weeks after the treatment. Bilateral disciform keratitis can occur as a complication of Reiter's syndrome. Also the possibility of secondary infection of the epithelial defect needs to be borne in mind.

    Clear cell sarcoma of the kidney (CCSK) accounts for 2-5% of all pediatric renal malignancies, and is known for its propensity to metastasize to bone and other sites. We are reporting two cases with bilateral CCSK that were diagnosed at our institution. One patient initially presented with bilateral renal masses, as well as pulmonary, hepatic and bone metastasis; while other present only with bilateral masses with no evident distant metastasis. Both patients received aggressive neo-adjuvant chemotherapy to decrease tumor size. One patient completed his designated treatment and initially showed complete remission (CR); eventually suffering from relapse. The other patient’s tumor progressed during the course of chemotherapy. Both cases manifested brain dissemination at the time of relapse or progression. This emphasizes the importance of staging stratification in CCSK. This also illustrates CCSK’s ability to metastasize to bone and other sites including the brain (a primary relapse site in our cases)

    1998-06-01

    This study reports a 64-year-old right-handed male who manifested bilateral tactile recognition deficits. They were diagnosed as bilateral tactile agnosia, since the patient showed difficulty in semantic association of objects despite preserved hylognosis and morphognosis. The patient had a bilateral lesion in the subcortical region of the angular gyrus. The case reported by Endo et al. (1992) had a right hand tactile agnosia due to a subcortical lesion in the left angular gyrus. Our findings support Endo's hypothesis that tactile agnosia occurs when the somatosensory association cortex is disconnected from the semantic memory store located in the inferior temporal lobe by a subcortical lesion of the angular gyrus. We suggest that the extent of the lesion in the tactual-semantic pathway is related to the severity of tactile agnosia and the types of the tactile naming errors.

  20. Bilateral fusion of permanent maxillary incisors

    2011-01-01

    Full Text Available Dental fusion is a rare developmental anomaly, which is included in the anomalies of tooth morphology or shape. Fusion can occur at the level of enamel or enamel and dentin, which results in the formation of a single tooth with enlarged clinical crown. Fusion is more common in deciduous dentition. Incisors are reported to be fused in primary and permanent dentition, but bilateral fusion is a rare occurrence. The prevalence of bilateral fusion in the permanent dentition is less frequent than unilateral fusion and is reported to be around 0.05%. The authors report a case of a 20-year-old male with bilateral fusion of maxillary central and lateral incisors. Multi-disciplinary treatment approach is essential to get the desired esthetic result. The best way to manage these difficult cases depends on a number of factors including the knowledge and technical skills of the practitioner.

    Bilateral giant hydrocele in an adult is a rare clinical entity. A 31-year-old man presented with painless bilateral scrotal swelling that had appeared at age 13 years and had increased very slowly since. Computed tomography and ultrasonography revealed collection of fluid on both sides of the scrotum. Giant scrotal hydrocele were diagnosed, and surgical excision was performed. The fluid volume was 1,050 ml in right, 645 ml in left. No inguinal hernia was found. Pathologic examination of the resected portion of the tunica vaginalis testis revealed inflammatory changes, and fluid cytology was negative. Eight months has passed, and there has been no evidence of recurrence.

    Full Text Available Atrial myxoma is the most common primary cardiac tumor. Its clinical presentation spreads from asymptomatic incidental mass to serious life-threatening cardiovascular complications. We report the case of a 44-year-old man with evening fever and worsening dyspnea in the last weeks, admitted to our hospital for acute pulmonary edema. The cardiac auscultation was very suspicious for mitral valve stenosis, but the echocardiography revealed a huge atrial mass with a diastolic prolapse into mitral valve orifice causing an extremely high transmitral gradient pressure. Awareness of this uncommon acute presentation of atrial myxoma is necessary for timely diagnosis and prompt surgical intervention.

    Full Text Available We describe an incident of development of acute pulmonary edema after the device closure of a secundum atrial septal defect in a 52-year-old lady, which was treated with inotropes, diuretics and artificial ventilation. Possibility of acute left ventricular dysfunction should be considered after the defect closure in the middle-aged patients as the left ventricular compliance may be reduced due to increased elastic stiffness and diastolic dysfunction. Baseline left atrial pressure may be > 10 mmHg in these patients. Associated risk factors for the left ventricular dysfunction are a large Qp:Qs ratio, systemic hypertension, severe pulmonary hypertension and paroxysmal atrial fibrillation.

    In this review article, we first present a brief overview of the vascular and neural components of diabetic retinopathy. Next, the multifocal electroretinogram (mfERG) technique, which can map neuroretinal function noninvasively, is described. Findings in diabetic retinal disease using the mfERG are reviewed. We then describe the progress that has been made to predict the onset and progression of diabetic retinopathy and edema in specific retinal locations, using quantitative models based on the mfERG. Finally, we consider the implications for the future of these predictive models.

    Full Text Available Nonsteroidal anti-inflammatory drugs (NSAIDs are nowadays widely used in ophthalmology to reduce eye inflammation, pain, and cystoid macular edema associated with cataract surgery. Recently, new topical NSAIDs have been approved for topical ophthalmic use, allowing for greater drug penetration into the vitreous. Hence, new therapeutic effects can be achieved, such as reduction of exudation secondary to age-related macular degeneration or diabetic maculopathy. We provide an updated review on the clinical use of NSAIDs for retinal diseases, with a focus on the potential future applications.

Corticosteroids are of therapeutic benefit because of their anti-inflammatory, antiangiogenic, and BRB-stabilizing properties. Delivery modes include periocular and intravitreal (via pars plana injection. To offset the short intravitreal half-life of corticosteroid solutions (~3 hours and the need for frequent intravitreal injections, sustained-release intravitreal corticosteroid implants have been developed. Dexamethasone intravitreal implant provides retinal drug delivery for ≤6 months and recently has been approved for use in the treatment of DME. Pooled findings (n=1,048 from two large-scale, randomized Phase III trials indicated that dexamethasone intravitreal implant (0.35 mg and 0.7 mg administered at ≥6-month intervals produced sustained improvements in best-corrected visual acuity (BCVA and macular edema. Significantly more patients showed a ≥15-letter gain in BCVA at 3 years with dexamethasone intravitreal implant 0.35 mg and 0.7 mg than with sham injection (18.4% and 22.2% vs 12.0%. Anatomical assessments showed rapid and sustained reductions in macular edema and slowing of retinopathy progression. Phase II study findings suggest that dexamethasone intravitreal implant is effective in focal, cystoid, and diffuse DME, in vitrectomized eyes, and in combination with laser therapy.

    To describe the high-resolution CT (HRCT) findings of re-expansion pulmonary edema (REPE) following a thoracentesis for a spontaneous pneumothorax. HRCT scans from 43 patients who developed REPE immediately after a thoracentesis for treatment of pneumothorax were retrospectively analyzed. The study group consisted of 41 men and two women with a mean age of 34 years. The average time interval between insertion of the drainage tube and HRCT was 8.5 hours (range, 1-24 hours). The patterns and distribution of the lung lesions were analyzed and were assigned one of the following classifications: consolidation, ground-glass opacity (GGO), intralobular interstitial thickening, interlobular septal thickening, thickening of bronchovascular bundles, and nodules. The presence of pleural effusion and contralateral lung involvement was also assessed. Patchy areas of GGO were observed in all 43 patients examined. Consolidation was noted in 22 patients (51%). The geographic distribution of GGO and consolidation was noted in 25 patients (58%). Interlobular septal thickening and intralobular interstitial thickening was noted in 28 patients (65%), respectively. Bronchovascular bundle thickening was seen in 13 patients (30%), whereas ill-defined centrilobular GGO nodules were observed in five patients (12%). The lesions were predominantly peripheral in 38 patients (88%). Of these lesions, gravity-dependent distribution was noted in 23 cases (53%). Bilateral lung involvement was noted in four patients (9%), and a small amount of pleural effusion was seen in seven patients (16%). The HRCT findings of REPE were peripheral patchy areas of GGO that were frequently combined with consolidation as well as interlobular septal and intralobular interstitial thickening.

    The purpose of the study was to evaluate the effi cacy of Kinesio Tape (Kinesio USA, Albequerque, NM) for reducing hand edema in individuals with hemiplegia post stroke. Seventeen individuals who experienced acute stroke were screened for visual signs of edema and were randomly assigned to experimental and control groups. The experimental group received Kinesio Tape that was applied to hand and forearm for 6 days in combination with standard therapy; the control group received standard therapy. Blinded raters assessed edema reduction via circumferential measurements. Application of Kinesio Tape did not result in statistically signifi cant reduction in edema. Large and medium effect sizes were seen for edema reduction at the metacarpophalangeal and wrist joints, respectively, with Kinesio Tape. Further research is warranted to investigate the utility of Kinesio Tape in edema reduction.

    A volumetric analysis of pre- and post-radiosurgery (PreSRS and PostSRS) edema in patients with cerebral metastases was performed to determine factors of a predictive model assessing the risk of developing increased edema relatively early after SRS. One-hundred-fourteen metastases in 55 patients were analyzed. Selection for this analysis required an MRI ≤ 30 days before SRS and an MRI ≤ 100 days after SRS. Tumor volumes were calculated on PreSRS, SRS, and PostSRS T1-weighted postgadolinium images while edema volumes were calculating using PreSRS and PostSRS fluid-attenuated inversion recovery MR images. An increase in edema was defined as an increase in measurable edema of at least 5%. We developed and evaluated a model predicting the relative risk (RR) of increased edema after SRS. Peritumoral edema increased in 18% (21/114) of the analyzed lesions. Melanoma/renal histology, recursive partitioning analysis class III, and prior WBRT carried RRs of developing postSRS edema increase of 2.45, 2.48, and 3.16, respectively (all P values edema/tumor ratio predicted for a RR of 1.007/ratio unit, and steroid dose at time of SRS predicted for a RR of 0.89/mg (all P values edema after SRS was developed based from these data and may be useful in identifying patients who might benefit from prophylactic anti-edema therapies before, during, or after SRS. This model could be used as the basis of inclusion criteria for prospective trials investigating novel anti-edema therapies.

    A case of bilateral fibrotic contracture of the infraspinatus muscles in a five-year-old Belgian Shepherd dog is described. The dog was presented with progressive forelimb lameness with postural and gait abnormalities three months after an episode of overexertion. When walking, the lower part of both forelimbs swung in a lateral arc causing a circumduction movement and in the standing position, the dog showed elbow adduction with external rotation of the distal part of both front limbs. Orthopaedic examination revealed bilateral atrophy of both infraspinatus and supraspinatus muscles and restriction in the range of motion of both shoulders, especially when attempting abduction and flexion. No specific findings were observed in the shoulder or elbow radiographs but hyperechogenic areas were evident in the ultrasonographic examination of both infraspinatus muscles. A diagnosis of fibrotic contracture of both infraspinatus muscles was established and bilateral tenectomy of the insertion tendons of the infraspinatus muscles was performed. Complete recovery of the animal was achieved after the surgery, which was confirmed in a long-term follow-up (10 months). In conclusion, physical examination and ultrasonography allowed a proper diagnosis of the condition, and tenectomy of the infraspinatus muscles resulted in a complete recovery of the patient even with bilateral involvement.

E-mail: saulocaldas@hotmail.com A case of bilateral queilosquise in a cattle two years old was reported. Clinically, there was cachexia, difficulty in grasping food and water intake. The clinical examination revealed that the nasal orifices were discontinuous with the upper lip, which allowed communication between the nostrils and mouth in its rostral portion, crowding of incisors (tweezers, as well as exposure of medium and the 2nd corner and of the tongue. In this case, the bilateral queilosquise was the result of flaws in fusion of the maxillary process and the medial nasal process and its surroundings, probably due to mineral deficiencies of pregnant cow. This pathogenesis was suggested by excluding other possible causes, the knowledge of the existence of mineral deficiencies in the region where the event occurred and bad nutritional status of pregnant female.

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

    Eighteen infantile cases with bilateral vocal cord paralysis were treated at our hospital from 1970 to 1993. All cases were diagnosed using a flexible fiberscope to examine the larynx. Direct laryngoscopy was performed under general anesthesia for the definite diagnosis and differential diagnosis from laryngomalacia, subglottic stenosis, tracheal stenosis, or laryngeal web. Bilateral vocal cord paralysis in children is a rare disease, there have been few and reported cases. Eight cases were male and 10 cases were female. Thirteen cases were congenital, 4 cases acquired and 1 case was unknown. The characteristic symptoms of bilateral vocal cord paralysis include normal or near normal phonation with inspiratory stridor which may progress to complete respiratory obstruction. Associated anomalies and diseases included 3 cases of immature infant, 2 of myelomeningocele, and single cases of Arnold-Chiari malformation, cerebral palsy, hydrocephalus, laryngomalacia, William's syndrome, Wiedemann-Beckwith syndrome, hypoxia, esophageal hiatus hernia, gastroesophageal reflex, spina bifida, COFS syndrome, and cerebral atrophy. Laryngeal function was completely recovered in seven cases following growth of the children incompletely recovered in five cases, and 2 cases retained right vocal cord paralysis. Tracheostomy was performed in 2 cases. One case died from the original disease, and the other one case was unknown. Swallowing function, phonation and development were good. Our experience suggests that the airway with bilateral vocal cord paralysis in children can be managed well without the need for tracheostomy.

Methods and Materials: The charts of all patients with the diagnosis of breast cancer treated with CS+RT at our facilities prior to 1993 were reviewed to identify patients with bilateral disease. A total of 50 patients identified as having bilateral breast cancer conservatively treated(BCT) served as the index population. Out of the 50 patients, 23 presented with synchronous bilateral breast cancer and 27 presented with metachronous bilateral breast cancer. A group of 984 patients with unilateral breast cancer (UCT) treated with CS+RT during the same time interval served as the first control group. A second control group was comprised of 42 patients with early stage bilateral breast cancer presenting during the same time interval treated with bilateral mastectomy (BMAST). Patients who had locally advanced disease in either breast or those patients treated exclusively for lobular carcinoma in situ in either breast were excluded from the analysis. Of the 42 BMAST patients, 33 presented with synchronous disease and nine presented with metachronous disease. Local-regional relapse rates were calculated from the date of treatment of each breast. Overall survival and distant relapse rates were calculated from the date of treatment of the second breast cancer diagnosed. Survival curves were calculated via the life table method and statistical comparisons between curves were performed using the log rank statistic. Chi square analysis was used to detect differences between categorical variables. Results: As of December 1995, the median follow-up of the bilateral conservatively treated patient population was 9.4 years. No statistically significant differences were noted

    Full Text Available Acute corneal edema is caused by various factors, with different levels of severity, and various forms of presentation. This paper reports the case of a male patient presenting with acute corneal edema without epithelium compromise, whose clinical picture, ophthalmological examination and additional tests did not reveal its etiology. Also, a review of available literature was conducted looking for all known causes of acute corneal edema, which are classified according to the etiology of the corneal edema into injury or inflammation of the corneal epithelium or stroma, endothelial dysfunction or increase in intraocular pressure.

    Perianeurysmal edema and aneurysm wall enhancement are previously described phenomenon after coil embolization attributed to inflammatory reaction. We aimed to demonstrate the prevalence and natural course of these phenomena in unruptured aneurysms after endovascular treatment and to identify factors that contributed to their development. We performed a retrospective analysis of consecutively treated unruptured aneurysms between January 2000 and December 2011. The presence and evolution of wall enhancement and perianeurysmal edema on MRI after endovascular treatment were analyzed. Variable factors were compared among aneurysms with and without edema. One hundred thirty-two unruptured aneurysms in 124 patients underwent endovascular treatment. Eighty-five (64.4 %) aneurysms had wall enhancement, and 9 (6.8 %) aneurysms had perianeurysmal brain edema. Wall enhancement tends to persist for years with two patterns identified. Larger aneurysms and brain-embedded aneurysms were significantly associated with wall enhancement. In all edema cases, the aneurysms were embedded within the brain and had wall enhancement. Progressive thickening of wall enhancement was significantly associated with edema. Edema can be symptomatic when in eloquent brain and stabilizes or resolves over the years. Our study demonstrates the prevalence and some appreciation of the natural history of aneurysmal wall enhancement and perianeurysmal brain edema following endovascular treatment of unruptured aneurysms. Aneurysmal wall enhancement is a common phenomenon while perianeurysmal edema is rare. These phenomena are likely related to the presence of inflammatory reaction near the aneurysmal wall. Both phenomena are usually asymptomatic and self-limited, and prophylactic treatment is not recommended. (orig.)

    Traumatic brain injury is a heterogeneous disorder resulting from an external force applied to the head. The development of cerebral edema plays a central role in the evolution of injury following brain trauma and is closely associated with neurologic outcomes. Recent advances in the understanding of the molecular and cellular pathways contributing to the posttraumatic development of cerebral edema have led to the identification of multiple prospective therapeutic targets. The authors summarize the pathogenic mechanisms underlying cerebral edema and highlight the molecular pathways that may be therapeutically targeted to mitigate cerebral edema and associated sequelae following traumatic brain injury.

    For the first time, we have implemented photoacoustic tomography (PAT) to image the water content of an edema in vivo. We produced and imaged a cold-induced cerebral edema transcranially, then obtained blood vessel and water accumulation images at 610 and 975 nm, respectively. We tracked the changes at 12, 24, and 36 h after the cold injury. The blood volume decreased after the cold injury, and the maximum area of edema was observed 24 h after the cold injury. We validated PAT of the water content of the edema through magnetic Resonance Imaging and the water spectrum from the spectrophotometric measurement.

    Full Text Available History of present illness: A 24-year-old male was brought in by paramedics status post motor vehicle collision (MVC into an electric pole and tree at high speed. The patient was an unrestrained driver who required extrication. The patient complained of left hip pain, left foot pain, and difficulty extending his bilateral lower extremities. He denied numbness or tingling to his lower extremities. The patient had normal vitals; his bilateral lower extremities were held in flexion at the hips, but otherwise had no obvious injuries. The patient’s pelvis was stable with palpable distal pulses and intact motor and sensory function of his distal lower extremities. Significant findings: The initial radiograph of the pelvis revealed bilateral hip dislocations. Small bony fragments were noted in the right hip joint, suggestive of an underlying fracture. The sacroiliac joints and the pelvic ring were intact. In the emergency department, bilateral hip reductions were performed using the Captain Morgan technique.1 The post-reduction film showed reduction of the bilateral hip dislocations with extensive comminuted and displaced fractures of the right and left acetabula. Discussion: Bilateral hip dislocations are extremely rare, occurring in only 1% of all hip dislocations,2 and require immense force, typically occurring in MVCs (74%.3-7 Associated injuries include fracture of the acetabulum or femoral head, sciatic nerve damage, and obstruction of the blood supply to the femoral head.8 X-ray imaging and CT scans are used to assess the injury and to detect intra-articular fragments.3 Definitive treatment is achieved by closed reduction if possible; otherwise open reduction is utilized.9 Post-reduction therapy includes a non-weight-bearing period of time. Complications include avascular necrosis of the femoral head, osteonecrosis, and posttraumatic arthritis, the occurrence of which can be decreased by early reduction.4,10-12 This patient underwent bilateral

    In order to evaluate the effect of acute upper airway obstruction upon pulmonary edema (PE) formation, we studied seven dogs that were subjected to inspiratory obstruction for three hours. Hypoxia was avoided by the administration of supplemental oxygen during the study period. Six dogs developed pulmonary vascular congestion, and four developed histologic findings of PE. Inspiratory intrapleural pressure decreased to -28 +/- 4 mmHg in dogs that developed PE and to -23 +/- 2 mmHg in dogs that did not. Transmural pulmonary artery pressure and pulmonary artery wedge pressure did not increase significantly. Central venous pressure during inspiration (CVPi) increased in all dogs, and CVP at end expiration (CVPe) was significantly higher in dogs with PE. Dogs that developed PE experienced a decrease in cardiac output and an increase in systemic vascular resistance. Furthermore, alveolar ventilation declined in dogs with PE, ultimately resulting in ventilatory failure. Pulmonary edema formation was not preceded by an increase in pulmonary vascular pressures but was associated with higher CVP, pulmonary vascular congestion, and hypercarbia.

    Baniya, Santosh, Christopher Holden, and Buddha Basnyat. Reentry high altitude pulmonary edema in the Himalayas. High Alt Med Biol. 18:425-427, 2017.-Reentry high altitude pulmonary edema (HAPE), a subset of HAPE, is a well recognized, life-threatening illness documented almost exclusively in the North and South Americans, who live at high altitude (>2500 m) and return to their homes after a brief sojourn of days to months at lower altitude. This phenomenon has not been reported in Sherpas or other people of Tibetan origin in Nepal or India. And it has rarely been reported from Tibet. In this study we document a case of reentry HAPE in Manang region (3500 m) of Nepal in a 7-year-old Nepali boy of Tibetan ancestry who fell ill when he ascended to his village (Manang, 3500 m) from Besisahar (760 m) in 1 day in a motor vehicle after spending the winter (December to March) at Besisahar with his family. With more motorable road access to high altitude settlements in the Himalayas, reentry HAPE may need to be strongly considered by healthcare professionals in local residents of high altitude; otherwise life-threatening complications may ensue as in our case report.

    Full Text Available Dominic McHugh, Bhaskar Gupta, Manzar Saeed King's College Hospital, Denmark Hill, London, England, UK Purpose: This study investigates the efficacy of an intravitreal gas injection in inducing a posterior vitreous detachment (PVD in patients with clinically significant diabetic macular edema refractory to laser therapy. Methods: A local ethics committee-approved technique of an intravitreal injection of pure perfluoropropane gas (C3F8 was performed for all participants. After a period of prone positioning, the patients underwent regular and detailed clinical review. Main outcome measures: The induction of a PVD, change in macular thickness, change in visual acuity. Results: A PVD was induced in all five eyes with subsequent signs of reduction in macular thickness and resolution of exudates. Mean visual improvement was 11 ETDRS (Early Treatment Diabetic Retinopathy Study letters (range 4–21. Apart from a transient vitreous hemorrhage in one eye, there were no significant treatment-related complications. Conclusion: The induction of a PVD by pneumatic retinopexy appears to have a significant influence on diabetic macular edema in eyes which have not successfully responded to macular laser therapy. A randomized clinical trial is justified on the basis of the initial promising data. Keywords: optical coherence tomography, OCT, posterior vitreous detachment, perfluoropropane

    Full Text Available Diabetes mellitus is a chronic disease which has multiple effects on different end-organs, including the retina. In this paper, we discuss updates on diabetic macular edema (DME and the management options. The underlying pathology of DME is the leakage of exudates from retinal microaneurysms, which trigger subsequent inflammatory reactions. Both clinical and imaging techniques are useful in diagnosing, classifying, and gauging the severity of DME. We performed a comprehensive literature search using the keywords “diabetes,” “macula edema,” “epidemiology,” “pathogenesis,” “optical coherence tomography,” “intravitreal injections,” “systemic treatment,” “hypertension,” “hyperlipidemia,” “anemia,” and “renal disease” and collated a total of 47 relevant articles published in English language. The main modalities of treatment currently in use comprise laser photocoagulation, intravitreal pharmacological and selected systemic pharmacological options. In addition, we mention some novel therapies that show promise in treating DME. We also review systemic factors associated with exacerbation or improvement in DME.

    The effects of glycerol on brain water and solute distribution in cerebral edema are not well known. In brail edema induced in dogs by focal freezing, tissue underlying the necrotic lesion had an elevated water content but the remainder of the brain was unaltered. Administration of glycerol to maintain plasma glycerol at about 35 mM dehydrated normal white matter, but water and solute contents of the edematous white matter were not changed. During the initial 3 hours of glycerol infusion, CSF pressure fell, but when the infusion was continued for 6 hours or more, a gradual rise in CSF pressure was observed. In three animals, the final CSF pressure was higher than preinfusion values. At this time, brain water content was significantly less than normal, but both CSF osmolality and glycerol concentration were higher than plasma. The data show that glycerol infusion can decrease intracranial volume towards normal by dehydration of normal, but not damaged, brain tissue. The rebound rise in CSF pressure observed during the continuous administration of glycerol cannot be explained by rehydration of brain tissue but may be related to alterations in CSF dynamics.

    Objective To investigate the mortality associated with cardiovascular diseases and the effect of estrogen treatment in women who underwent unilateral or bilateral oophorectomy before menopause. Design We conducted a cohort study with long-term follow-up of women in Olmsted County, MN, who underwent either unilateral or bilateral oophorectomy before the onset of menopause from 1950 through 1987. Each member of the oophorectomy cohort was matched by age to a referent woman from the same population who had not undergone any oophorectomy. We studied the mortality associated with cardiovascular disease in a total of 1,274 women with unilateral oophorectomy, 1,091 women with bilateral oophorectomy, and 2,383 referent women. Results Women who underwent unilateral oophorectomy experienced a reduced mortality associated with cardiovascular disease compared with referent women (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.67–0.99; P = 0.04). By contrast, women who underwent bilateral oophorectomy before age 45 years experienced an increased mortality associated with cardiovascular disease compared with referent women (HR, 1.44; 95% CI, 1.01–2.05; P = 0.04). Within this age stratum, the HR for mortality was significantly elevated in women who were not treated with estrogen through age 45 years or longer (HR, 1.84; 95% CI, 1.27–2.68; P = 0.001) but not in women treated (HR, 0.65; 95% CI, 0.30–1.41; P = 0.28; test of interaction, P = 0.01). Mortality was further increased after excluding deaths associated with cerebrovascular causes. Conclusions Bilateral oophorectomy performed before age 45 years is associated with increased cardiovascular mortality, especially with cardiac mortality. However, estrogen treatment may reduce this risk. PMID:19034050

In the first decade of life, patients usually develop a decrease in visual acuity. Long-term visual outcomes can be poor due to the limited number of known successful treatments. Purpose: The purposes of this study were to present, for the first time, a p.Arg197Cys missense mutation in the RS1 gene (OMIM: 300839 in a four-generation Italian family with RS1 and to examine the clinical response to the treatment with acetazolamide tablets alone or in combination with dorzolamide eye drops as assessed by spectral-domain optical coherence tomography (SD-OCT. Methods: Eleven individuals, including two brothers with RS1 (patients 1 and 2, underwent a full medical history examination and a comprehensive ocular assessment that involved SD-OCT, fluorescein angiography, electroretinography and DNA analysis. Each RS1 patient received oral acetazolamide (375 mg daily during the first three months. Thereafter, patient 1 continued only with dorzolamide eyedrops three times a day for a period of three months, while patient 2 spontaneously stopped both medications. Results: Sequence analysis of the RS1 gene identified a hemizygous c.589C>T (p.Arg197Cys missense mutation in exon 6, which has not been previously reported in an Italian family. A different response to the medical therapy was observed in the four eyes of the two affected brothers hemizygous for

    Full Text Available Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis.

  10. Bilateral post-traumatic gluteal compartment syndrome: A case report and review of literature

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Gluteal compartment is a rare site for compartment syndrome. Gluteal compartment syndrome has most commonly been described in the literature as occurring after prolonged immobility associated with substance abuse, improper operative positioning, sickle cell-induced infarct, post-traumatic and spontaneous superior gluteal artery rupture, exercise, and post-arterial embolization of the internal iliac artery prior to abdominal aortic aneurysm repair. Trauma is rarely associated with this syndrome. Gluteal compartment syndrome occurs in approximately 0.9% of trauma patients. Posttraumatic gluteal compartment syndrome develops because of edema with traumatic contusions, crush injuries and hematoma formation due to blunt superior or inferior gluteal artery injuries in all compartments of the gluteal region Only 6 previous cases have been reported in the literature. Two previous cases involved positioning for urological procedures, while the other cited causes of bilateral gluteal compartment syndrome include exercise-induced, trauma, and prolonged immobilization from substance abuse. One of the most immediately devastating results of a missed compartment syndrome is the risk of the development of rhabdomyolysis with the resulting squeal of myoglobinuria, hyperkalemia, and acidosis resulting in renal failure, shock, multiple organ failure, disseminated intravascular coagulation, and possibly death. Here we report a case of posttraumatic bilateral compartment syndrome which developed secondary to pressure due to patient being trapped under a vehicle following a vehicular accident. He was operated upon and a bilateral fasciotomy was done. Although he did not develop any renal complications, the sciatic nerve palsy on the left side did not recover. The patient is still under follow up.

    Conclusion and importance: Bilateral superior rectus transposition with medial rectus recession appears to be a useful procedure for surgical treatment of bilateral sixth nerve palsy with minimal side effects. Given its potential for reduced risk of anterior segment ischemia (ASI, it may have especially good value in the select group of patients at risk for ASI. Studies with larger sample size and longer follow up are needed to further evaluate this procedure and elucidate the variables in surgical technique for superior rectus transposition.

  12. Hardware Implementation of a Bilateral Subtraction Filter

    2009-01-01

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    2011-04-01

    Full Text Available Abstract Background Peritumoral edema is a characteristic feature of malignant glioma related to the extent of neovascularisation and to vascular endothelial growth factor (VEGF expression. The extent of peritumoral edema and VEGF expression may be prognostic for patients with glioblastoma. As older age is a negative prognostic marker and as VEGF expression is reported to be increased in primary glioblastoma of older patients, age-related differences in the extent of peritumoral edema have been assessed. Methods In a retrospective, single-center study, preoperative magnetic resonance imaging (MRI scans of steroid-naïve patients (n = 122 of all age groups were analysed. Patients with clinically suspected, radiologically likely or known evidence of secondary glioblastoma were not included. Extent of brain edema was determined in a metric quantitative fashion and in a categorical fashion in relation to tumor size. Analysis was done group-wise related to age. Additionally, tumor size, degree of necrosis, superficial or deep location of tumor and anatomic localization in the brain were recorded. Results The extent of peritumoral edema in patients >65 years (ys was not different from the edema extent in patients ≤ 65 ys (p = 0.261. The same was true if age groups ≤ 55 ys and ≥ 70 ys were compared (p = 0.308. However, extent of necrosis (p = 0.023, deep tumor localization (p = 0.02 and frontal localisation (p = 0.016 of the tumor were associated with the extent of edema. Tumor size was not linearly correlated to edema extent (Pearson F = 0.094, p = 0.303 but correlated to degree of necrosis (F = 0.355, p Conclusion Age at diagnosis does not determine degree of peritumoral edema, and tumor localization in the white matter is associated with greater extent of edema. The area of necrosis is reflective of volume of edema. In summary, the radiographic appearance of a glioblastoma at diagnosis does not reflect biology in the elderly patient.

    Full Text Available Context. The possibility of cephalic venous hypertension with the resultant facial edema and elevated cerebrospinal fluid pressure continues to challenge head and neck surgeons who perform bilateral radical neck dissections during simultaneous or staged procedures. Case Report. The staged procedure in patients who require bilateral neck dissections allows collateral venous drainage to develop, mainly through the internal and external vertebral plexuses, thereby minimizing the risks of deleterious consequences. Nevertheless, this procedure has disadvantages, such as a delay in definitive therapy, the need for a second hospitalization and anesthesia, and the risk of cutting lymphatic vessels and spreading viable cancer cells. In this paper, we discuss the rationale and feasibility of preserving the external jugular vein. Considering the limited number of similar reports in the literature, two cases in which this procedure was accomplished are described. The relevant anatomy and technique are reviewed and the patients’ outcomes are discussed. Conclusion. Preservation of the EJV during bilateral neck dissections is technically feasible, fast, and safe, with clinically and radiologically demonstrated patency.

    Previous studies have indicated edema may be involved in the pathophysiology following hypoxic-ischemic encephalopathy (HIE), and melatonin may exhibit neuro-protection against brain insults. However, little is known regarding the mechanisms that involve the protective effects of melatonin in the brain and peripheral tissues after HIE. The present study aimed to examine the effects of melatonin on multiple organs, and the expression of edema related proteins in a neonatal rat model of hypoxic-ischemic brain damage (HIBD). One hundred ninety-two neonatal rats were randomly divided into three subgroups that underwent a sham surgery or HIBD. After the HIBD or sham-injury, the rats received an intraperitoneal injection of melatonin or an equal volume vehicle, respectively. We investigated the effects of melatonin on brain, kidney, and colon edema via histological examination and the expression of edema related proteins, including AQP-4, ZO-1 and occludin, via qPCR and western blot. Our data indicated (1) Melatonin reduced the histological injury in the brain and peripheral organs induced by HIBD as assessed via H-E staining and transmission electron microscopy. (2) Melatonin alleviated the HIBD-induced cerebral edema characterized by increased brain water content. (3) HIBD induced significant changes of edema related proteins, such as AQP-4, ZO-1 and occludin, and these changes were partially reversed by melatonin treatment. These findings provide substantial evidence that melatonin treatment has protective effects on the brain and peripheral organs after HIBD, and the edema related proteins, AQP4, ZO-1, and occludin, may indirectly contribute tothe mechanism of the edema protection by melatonin.

    Full Text Available Rafael Campos Polo, Consuelo Rubio Sánchez, Diego Manuel García Guisado, María José Díaz Luque Unit of Retina, Department of Ophthalmology, Hospital Virgen del Puerto, Plasencia, Cáceres, Spain Purpose: To assess the effectiveness and safety of intravitreal aflibercept in clinically significant diabetic macular edema (DME in daily clinical practice. Methods: Prospective, open-label, single-center study. Anti-vascular endothelial growth factor naïve patients with clinically significant DME received intravitreal injections of aflibercept 2 mg, five monthly doses followed by a fixed schedule every 2 months for 12 months. The mean change in best-corrected visual acuity (BCVA (Early Treatment Diabetic Retinopathy Study [ETDRS] letters was the primary outcome. Results: The mean BCVA improved significantly as compared with baseline at 12 months of treatment (47.3 [14.2] vs 62.2 [13.9] ETDRS letters, P<0.001. Significant improvement in BCVA was already observed at visit 2 after the loading doses of aflibercept. At 12 months, gains in ETDRS letters were documented in all eyes (100%, with gains ≥10 letters in 89.6%, ≥15 letters in 65.5%, and ≥20 letters in 6.9% (n=2. A significant reduction in central macular thickness from a mean of 460.5 (11.8 µm at baseline to 229.0 (43.8 µm at 12 months (P<0.001 was observed. Significant reductions of central macular thickness were already observed after the loading doses and continued lowering throughout the study period. No adverse events occurred. Conclusion: Aflibercept as a first-line therapy was effective and well tolerated for treating clinically significant DME in naïve patients in daily practice. Successful results in terms of improvement of visual and reduction in central macular thickness contribute to provide evidence for the positioning of aflibercept as a first-line indication of newly diagnosed clinically significant DME.

    1990-01-01

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions

    2016-01-01

    Introduction Isolated traumatic fractures of both Patellae, occurring at the same time, in an otherwise healthy person, are very rare. The Patella, as a subcutaneous and a cancellous bone, is vulnerable to injury. However, simultaneous injury to both Patellae without the involvement of any other bony injuries occurs infrequently, and only a few cases have been reported in the literature. Case Presentation We report a rare case of isolated, traumatic bilateral Patella fracture with unusual fracture patterns and briefly review the literature. Conclusions In simultaneous bilateral Patella fractures, good functional outcome can be expected following a stable surgical fixation and a structured rehabilitation regime. However, personality of the fracture determines salvage versus sacrifice of the Patella. PMID:27218047

    2017-12-01

    Bilateral masseter muscle hypertrophy is an alteration in shape and thickness of the masseter muscles that can modify the width of the lower face causing aesthetic and functional problems. A 21-year-old man was referred to the Department of Maxillofacial Surgery at the Civil Hospital in Brescia by his dentist for an evaluation of his facial appearance with a square-face type. To reduce the undesirable facial appearance, a surgical intraoral approach was performed; the procedure includes the bilateral dissection of the masseter muscle, partial lipectomy, and the ostectomy of the mandibular angle assisted by a surgical guide built on a stereolithographic model. The patient was satisfied with the functional and aesthetic outcomes of both the profile and the frontal views. There was no evidence of complication at a 1-year follow-up. This new method yields optimal aesthetic results with an enhanced outline of the lower face.

    Full Text Available Elastofibroma dorsi is a rare, slow-growing soſt tissue tumor of the chest wall. The tumor typically located under the lower pole of the scapula. A 57-year-old woman who had retiredas a teacher, presented with a 1-year history of pain on the back and with a 3-month history of swelling located under the leſt scapula. Computed tomography and magnetic resonance imaging showed bilateral, solid soſt tissue tumors under the scapula. She underwent total resection of the tumor on the leſt side. Tumor was diagnosed histopathologically as elastofibroma. Elastofibroma dorsi can be undetermined because of its localization. Radiological examination is important especially on diagnosis of bilateral localization.

    This case study describes a 37-year-old male who suffered a bilateral transverse acetabulum fracture with a fracture of the posterior wall and a double-sided dorsal hip dislocation in combination with a left-sided femoral head fracture (Pipkin IV) while skiing in a "fun park". The accurate diagnosis and presurgical planning was made by means of a computed tomography (CT) scan and a subsequent 3D reconstruction. After a primarily executed shielded repositioning of the bilateral hip dislocationearly secondary and anatomical reconstruction of the double-sided acetabulum fracture was possible using the Kocher-Langenbeck approach. A consistent physiotherapy as well as rehabilitation finally led to a positive clinical result for the patient.

  10. Bilateral Breast Masses with a Rare Etiology

    2013-01-01

    Full Text Available Breast masses have a variety of benign and malignant etiologies. We present the case of a 28-year-old woman with bilateral large painful breast masses that developed rapidly in the three weeks before first presentation. Further investigation revealed bilateral ovarian masses. Biopsies of both ovarian masses were taken, and the pathology reported Burkitt’s lymphoma. Additional staging with a PET scan was suggestive of bone marrow involvement, but bone marrow biopsy was negative. Examination of the cerebrospinal fluid did not identify malignant cells. The patient underwent CODOX-M/IVAC chemotherapy, and a complete response was demonstrated after one cycle of treatment. Six months after finishing chemotherapy the patient remained in complete remission. To our knowledge this is the first case reporting simultaneous involvement of breast, ovaries, and bones in Burkitt’s lymphoma. Gynecologists and oncologists should be aware of this pattern. Polychemotherapy treatment must be initiated rapidly with curative intent.

    Full Text Available 【Abstract】There is a dearth of case reports de-scribing simultaneous bilateral patellar tendon ruptures in the medical literature. These ruptures are often associated with systemic disorders such as lupus erythematosus or chronic steroid use. The author describes a case of a 24-year-old man who sustained traumatic bilateral patellar ten-don ruptures without any history of systemic disease or steroidal medication. We repaired and reattached the rup-tured tendons to the patella and augmented our procedure with allogeneic tendon followed by wire loop reinforcement. One year after operation, the patient regained a satisfactory range of motion of both knees with good quadriceps strength and no extensor lag. The recurrent microtrauma from a history of intense sports activity and a high body mass index may have played an important role in this trauma event.

    Fibroadenomas are benign lesions of breast commonly found in young age group. These focal tumours contain both mesenchymal and glandular tissue. Giant juvenile fibroma of breast is rare variant of fibroadenoma found usually in less than 20 years of age. They present with rapid enlargement of single or multiple, discrete, painless large nodule of breast. A 14-years-old premenarche girl presented with large bilateral breast lumps for two months. FNAC showed features of juvenile fibroadenoma. Breast conserving surgical excision of lumps was performed and histopathology confirmed the diagnosis of juvenile fibroadenoma. Giant juvenile fibroadenomas are characterised by rapid enlargement of encapsulated mass. The aetiology is unknown, although end-organ hypersensitivity to normal level of estrogen is postulated. We present a case of bilateral giant juvenile fibroadenoma for its rarity.

    2008-06-01

    Full Text Available Cerebral arteriovenous fistula (AVF is a vascular malformation that is rare in the pediatric population. Older children with cerebral AVF tend to present with neurologic problems related to intracranial venous hypertension or intracranial hemorrhage. Cardiac and pulmonary complications following acute neurologic injury such as subarachnoid hemorrhage are common in adults, but are rarely reported in children. However, complications have been reported in cases of enterovirus 71 rhombencephalitis in infants and children and can cause high morbidity and mortality. Here, we report a 14-year-old boy who presented with cardiac failure associated with pulmonary edema following cerebral hemorrhagic stroke due to AVF. After aggressive investigation and management, we intervened before significant hypoxia and hypotension developed, potentially reducing the risk of long-term adverse neurologic consequences in this patient.

    Full Text Available Negative pressure pulmonary edema (NPPE is a dangerous and potentially fatal condition with a multifactorial pathogenesis. Frequently, NPPE is a manifestation of upper airway obstruction, the large negative intrathoracic pressure generated by forced inspiration against an obstructed airway is thought to be the principal mechanism involved. This negative pressure leads to an increase in pulmonary vascular volume and pulmonary capillary transmural pressure, creating a risk of disruption of the alveolar-capillary membrane. The early detection of the signs of this syndrome is vital to the treatment and to patient outcome. The purpose of this review is to highlight the available literature on NPPE, while probing the pathophysiological mechanisms relevant in both the development of this condition and that involved in its resolution.

    Full Text Available Negative pressure pulmonary edema (NPPE is one of the common complications of upper airway obstruction seen by anesthesiologist during either in induction or emergence sometimes both. Patients who have experienced NPPE are generally healthy without comorbidities. NPPE is a result of marked decrease in intrathoracic pressure caused by ventilator efforts against a closed glottis resulting in disruption of normal intravascular Starling mechanism, leading to transudation of intravascular protein, and fluids into the pulmonary interstitium. The onset of NPPE is usually rapid and without prompt recognition and intervention, the outcome can be fatal. This case report is of a 40-year-old female adult, who underwent right-sided percutaneous nephrolithotomy for stone in the right kidney otherwise uncomplicated surgical procedure.
