Full Text Available The human face is composed of small functional and cosmetic units, of which the eyes and periocular region constitute the main point of focus in routine face-to-face interactions. This dynamic region plays a pivotal role in the expression of mood, emotion, and character, thus making it the most relevant component of the facial esthetic and functional unit. Any change in the periocular unit leads to facial imbalance and functional disharmony, leading both the young and the elderly to seek consultation, thus making blepharoplasty the surgical procedure of choice for both cosmetic and functional amelioration. The applied anatomy, indications of upper eyelid blepharoplasty, preoperative workup, surgical procedure, postoperative care, and complications would be discussed in detail in this review article.

Full Text Available Sixteen years after scleral buckle surgery with a hydrogel episcleral exoplant, a 43-year-old woman presented with progressive binocular diplopia, ptosis, and an expanding mass in her upper eyelid. She underwent surgical removal of the hydrogel exoplant through an anterior approach. The exoplant proved to be friable, fragmented, and encapsulated in a fibrous tissue; the exoplant was removed in its entirety. Postoperatively, the eyelid mass resolved, while her diplopia and ptosis improved slightly.

The aim of this study was to determine the relation of the vector force needed to lift the upper eyelids and the degree of exophthalmos (EX). In the 109 magnetic resonance imaging films, the degree of EX (the shortest distance from the cornea to the line connecting both lateral orbital rims), the anterior angle (θ, an angle formed from the lower margin of the upper eyelid-superior transverse ligament (STL)--with a parallel line connecting the supraorbital rim and the infraorbital rim in the sagittal film), the length from the STL to the upper eyelid margin (levator length [LL]), the thickness of the STL (WT), and the thickness the of levator palpebrae (LT) were measured.The average EX was 14.5 ± 2.35  mm. The average θ was 33.84 ± 2.15 degrees. The vector force needed to lift the upper eyelids (cos θ) was 0.83. The average LL was 21.0 ± 1.54  mm. The average WT was 1.07 ± 0.22  mm. The average LT was 1.69 ± 0.30  mm. There was a significant positive relationship between the EX and age (P = 0.022). The EX in those younger than 20 years (12.8 ± 2.06) was significantly lesser than that of the other age groups. There was no significant relationship between the EX and cos θ. However, there was a significant positive relationship between the EX and the LL. There was a significant positive relationship between LL and LT, and between LL and WT.The farther the eyeball protrudes, the longer the LL is needed. The longer the LL is, the thicker the levator muscle and STL.

Cosmetically unappealing lax, wrinkled eyelid skin may result from various processes including connective tissue diseases, natural aging, and blepharochalasis. Since the end-stage eyelid changes due to several different processes are similar, the presence or absence of prior chronic or recurrent eyelid edema is an important differentiating point. We review blepharochalasis and provide a logical approach to its differential diagnosis.

Management of upper airway edema caused by hereditary angioedema

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.

Reconstruction of the Upper Eyelid with Flaps and Free Grafts after Excision of Basal Cell Carcinoma

Alessandro Guido Actis

2011-11-01

Full Text Available Purpose: To describe a reconstructive technique of the superior eyelid with flaps and free grafts after excision of a basal cell carcinoma. Methods: Single case report of a 79-year-old woman who presented to our hospital with a basal cell carcinoma of the upper eyelid margin with initial erosion. Results: A large and full-thickness excision of the carcinoma was performed. The reconstruction technique should be customized to the individual patient. In this case, the use of a full-thickness tarsal graft from the contralateral upper eyelid, followed by an ipsilateral bipedicled flap and finally by a skin graft, was an effective surgical procedure, performed in one stage, without complications, and with good functional and esthetic results. Conclusions: Malignant neoplasms represent the leading cause of plastic reconstruction in the orbital region. Surgical techniques must be individualized for each patient and for each type of carcinoma. Reconstructive techniques with free grafts and flaps yield excellent results in the orbital region, particularly when some advice and a few fundamental rules are followed, namely accurate hemostasis of the receiving graft bed by moderate use of diathermy, careful suturing of the edges, and application of a compressive dressing for at least 4 days. Postoperative complications are very rare.

To report the histopathological diagnosis ofeyelid tumors and to study the prevalence of eyelid tumors in Chiang Mai University Hospital Chiang Mai, Thailand. A retrospective review of medical and pathological records ofpatients diagnosed as eyelid tumor that underwent histopathological biopsy between January 2007 and December 2013 in Chiang Mai University Hospital was done. Three hundred sixteen cases of eyelid tumors were reviewed. The mean age at diagnosis was 54.2 +/- 19.6 years (range 1 month-99 years), women were 59.5% (n = 188) and men 40.5% (n = 128). The tumor sites were left lower eyelid (27.5%), right upper eyelid (24.4%), right lower eyelid (21.2%), and left upper eyelid (18.7%). There were 204 (64.6%) benign tumors and 112 (35.4%) malignant tumors. Nevi were the most common in benign group (16.4%) and basal cell carcinoma was the most common eyelid malignancy (18.0%). The most common histopathological diagnosis for benign eyelid tumor was nevus, while the most common malignant eyelid tumor was basal cell carcinoma at Chiang Mai University Hospital.

Solitary eyelid schwannoma

2014-01-01

Full Text Available Schwannomas are rare benign tumors arising from Schwann cells of peripheral nerves that form the neural sheath. While there have been reports of such tumors in the orbit, solitary schwannomas arising from the eyelids are very rare. There are reports of schwannomas being erroneously diagnosed as chalazion, inclusion cysts or even eyelid malignancy. We are reporting a case of a 20-year-old female who presented with a painless, non-tender, slow-growing mass in the upper eyelid of the right eye. The external appearance of the mass was suggestive of an implantation cyst of the eyelid and it could be completely excised as it had a well-defined capsule. Histopathological examination showed characteristic hypercellular and hypocellular areas with fusiform nuclei that tended to form palisades. The purpose of reporting this case of schwannoma in a young female is to recommend the inclusion of this entity as a differential diagnosis of well-defined lid tumors.

Full Text Available Background. To assess Cutler-Beard procedure results in patients after wide excision of malignant eyelid tumours. Materials and Methods. The records of two women and two men (four patients referred to our clinic with eyelid mass complaints and malign eyelid tumour diagnosis according to the histopathological examination were examined retrospectively. Results. The patients were 60–73 years old and their average age was 66±11.10. The follow-up period of the cases was 16 (6–25 months. Total excisional biopsy was applied to all patients and then Cutler-Beard full thickness lid reconstruction was done because of the wide localization of the tumour. The patients’ diagnoses were consistent with basal cell carcinoma, sebaceous gland carcinoma, eyelid lymphoma, and squamous cell carcinoma. The patients’ eyelids were separated from each other 1 month postoperatively with a second operation. Superior eyelid entropium and blepharochalasis were seen in one patient during followup. Conclusions. Cutler-Beard flap is a successful procedure for superior eyelid tumours accompanied by wide tissue loss. The long-time closure of the eyelids and the need for secondary surgery are the major disadvantages of this procedure. Our experience with this procedure will reveal better results with large case series.

Full Text Available Background: The aim of this study was to minimize edema and ecchymosis following rhinoplasty through a closed drainage system to address concealed hemorrhage.Methods: This study was designed as a prospective، double blinded, randomized contr-olled study. Fifty one patients who underwent septorhinoplasty were included in this study and divided in two groups. In group A, a closed drainage system was applied in the most dependent posterior septal area following septal harvesting. Concealed bloody secretions were drained out of mouth in a vacutaner tube during three concecutive post operative days. In control group, group B, exactly the same classic rhinoplasty opera-tion by the same surgeon was done as for study group except omitting the closed drainage system. Degree of supra-tip and eyelid edema was evaluated on post operative days through photographic and software image analysis. Edema and ecchymosis rating of eyelids and ecchymosis of paranasal and cheek area done based on photographic analysis by independent plastic surgeons using a defined grading system.Results: Eyelid ecchymosis was reduced significantly on post operative day 14 in the study group (P=0.03. Ecchymosis of paranasal and check was reduced considerably likewise on days 7 and 14 in group A using Mann-Whitney test (P=0.03. There was no significant deference regarding supra tip edema on post operative days. The same hold true for the eyelids edema.Conclusion: Significant decrement observed in eyelids ecchymosis on day 14 and para-nasal and cheek ecchymosis on postoperative days 7 and 14 in study group. There were no positive effects regarding supra tip and eyelid edema reduction using closed drainage system to evacuate concealed haemorrhage in posterior septum space. There could be different etio-pathologies for two common morbidities following rhinoplasty that should be addressed separately.

Toft, Peter B

2016-01-01

To review and present the results of a one-step method employing a free tarsal plate graft and a myocutaneous pedicle flap plus a free skin graft for reconstruction of large upper eyelid defects after tumour surgery. This was a retrospective case-series of 8 patients who underwent reconstruction of the upper eyelid after tumour removal. The horizontal defect involved 50-75% of the lid (3 pts.), more than 75% (3 pts.), and more than 75% plus the lateral canthus (2 pts.). The posterior lamella was reconstructed with contralateral upper eyelid tarsal plate. The anterior lamella was reconstructed with a laterally based myocutaneous pedicle flap in 7 patients, leaving a raw surface under the brow which was covered with a free skin graft. In 1 patient with little skin left under the brow, the anterior lamella was reconstructed with a bi-pedicle orbicularis muscle flap together with a free skin graft. All patients healed without necrosis, did not suffer from lagophthalmos, achieved reasonable cosmesis, and did not need lubricants. In one patient, a contact lens was necessary for three weeks because of corneal erosion. One patient still needs a contact lens 3 months after excision to avoid eye discomfort. Large upper eyelid defects can be reconstructed with a free tarsal plate graft and a laterally based myocutaneous pedicle flap in combination with a free skin graft. Two-step procedures can probably be avoided in most cases.

[Treatment of eyelid retraction in Grave's disease by recession of the levator complex].

Fichter, N; Schittkowski, M; Guthoff, R F

2004-11-01

The chronic stage in Grave's orbitopathy is characterised by fibrotic changes within the orbital soft tissues, especially the extraocular muscles. Retraction of the eyelids is a common clinical feature of this phenomenon. To solve this problem several techniques for lengthening the upper eyelid have been described with variable rates of success. In this report we describe our modified Harvey's technique for the correction of upper eyelid retraction which includes a complete recession of the Muller's muscle/levator complex from the tarsal plate without the interposition of a spacer. Finally only the skin and the superficial orbicularis muscle are sutured. We also report about our results with this procedure. 8 patients (1 male, 7 female) with lid retraction in Grave's ophthalmopathy were recorded who had undergone the modified lengthening technique by an external approach between 2001 and 2004. Four patients underwent a bilateral procedure and 1 patient showed a significant under-correction, necessitating reoperation. So a total of 13 procedures were included in this follow-up study. Beside the common ophthalmological examination, special interest was put in the difference of the two eyelid apertures in primary position pre- and postoperatively. Within a follow-up period of at least 3 months we recorded an averaged lengthening of the upper eyelid of 3.1 mm. The difference of the two eyelid apertures in primary position improved from 2.2 mm preoperatively to 1.0 mm postoperatively. Only 1 patient needed reoperation because of a significant under-correction. There were no late over-corrections observed. The modified Harvey's technique to lengthen the upper eyelid is a safe and effective method to reduce upper eyelid retraction in Grave's disease. An eventually required orbital decompression or extraocular muscle surgery has to be done before the lid surgery.

Full Text Available Total upper and lower eyelid defect is usually secondary to the excision of malignant or benign tumours, trauma and burns. Reconstruction of this type of defect is important not only for the cosmetic result, but also for coverage of the cornea an d prevent injury to eyeball. Pyogenic granuloma is usually preceded by the history of trauma to the eyelid. But reports of giant pyogenic granuloma of both upper and lower eyelid are rare. We present here a ten year old boy diagnosed primary immune deficient with a large fungating mass over both upper and lower eyelid, which was excised and total upper and lower eyelid defect was reconstructed with paramedian forehead flap. Histopathology revealed pyogenic granuloma. Post operatively c hild had good lid movements.

A patient was found to have a metallic foreign body in the left anterior orbit on CT imaging, but the foreign body was not evident on clinical examination. On high-resolution ultrasonography, an object was identified in the left upper eyelid; however, the typical shadow with metallic foreign bodies was not seen. A high-power oscillating magnet was then applied to the eyelid, which revealed a subcutaneous metallic foreign body in the left upper eyelid. When used in conjunction, the high-resolution ultrasound and oscillating magnet successfully localized and facilitated retrieval of the metallic foreign body from the left upper eyelid.

Morgellons disease is characterized by complaints of uncomfortable skin sensations and fibers emanating from nonhealing skin lesions. Morgellons disease is well-known in the dermatology and psychiatry literature, where it is typically considered a subtype of delusional parasitosis, but it has not yet been described in the ophthalmology literature. A patient with self-reported Morgellons disease is presented, who was referred for evaluation of left lower eyelid ectropion. She reported that her skin was infested with fibers that were "trying to get down into the eyelid." On examination, she had ectropion of the left lower eyelid, broken cilia, and an ulcerated left upper eyelid lesion concerning for carcinoma. Biopsy of the lesion was consistent with excoriation. Treatment of her ectropion was deferred out of concern for wound dehiscence, given the patient's aggressive excoriation behavior. This case is presented to make the ophthalmologist aware of this disorder and to highlight the appropriate clinical management.

To determine the functional and cosmetic outcome of using skin graft from prepuce (after circumcision) to reconstruct eyelids in congenital lid coloboma. Four male infants with large eyelid coloboma and marked exposure keratopathy were included. All the patients were selected from the outpatient clinic of Tanta University Eye Hospital, Egypt from March 2006 till August 2009. One-stage reconstruction was used to repair the defect. For upper eyelid coloboma, sliding tarsoconjunctival flap with a free skin graft from of skin of prepuce (after circumcision) was done.For lower lid coloboma, conjunctival dissection with reflection over the cornea with use of a free skin graft from prepuce. All infants had large unilateral defect, 3 upper lids and 1 lower lid. The cosmetic and functional outcome of using skin of the prepuce was satisfactory with good color match in all cases. Also functional and cosmetic results of tarsoconjunctival sliding flap was excellent. All the cases were followed up for a period ranged from 7 to 36 months. Tarsoconjunctival rotational flap and the use of skin of prepuce are very helpful and seems to be an adequate method of reconstruction of large eyelid defect in male patients when the usual donor sites for skin grafts are not available as in infants.

Eyelid malpositions: An overview

Directory of Open Access Journals (Sweden)

Marian Pauly

2017-01-01

Full Text Available Eyelid malpositions are the result of forces acting upon the eyelid margin. A normal eyelid should have a quick return snap to the eyeball. Frequently, tendon laxity at the medial and lateral canthi will render the eyelid margin unstable making it susceptible to contractile forces. Based on the contractile forces either entropion, ectropion, retraction or lagophthalmos can occur. The goal in treating a given eyelid malposition is to reposition the eyelid so that the new healing forces will overcome the pathologic forces. The common approaches include eyelid and canthal tendon tightening, eyelid retractor advancement or recession and skin grafting or transposition flaps. This review article briefly describes the various aspects of lid malpositions in detail.

Eight months later, he presented with erythema and swelling of right upper eyelid. An incisional biopsy was performed, reporting extranodal marginal zone B cell lymphoma. when a tumour at the site of a gold weight implant is refractory to treatment, it is essential to perform an incisional biopsy to establish the histopathological diagnosis. Ocular adnexal lymphomas are relatively common. The presence of foreign material can cause chronic inflammation that could be the stimulus for the development of a lymphoproliferative disorder.

Bhattacharya, Mallar; Kallet, Richard H; Ware, Lorraine B; Matthay, Michael A

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.

M Rafieian

2012-10-01

Full Text Available Introduction: Entropion and ectropion with involutional changes are the most common eyelid malpositions. Entropion is a condition in which the eyelid margin turns inwards against the globe and ectropion is a malposition in which the lid turns outwards or is pulled away its normal position from the globe. Knowledge of eyelid problems and their abnormalities is a key to plan a successful surgical procedure. Methods: This descriptive study lasted from Sep. 2008 to March 2009. We evaluated 78 patients with eyelid malpositions who referred to educational hospitals of Yazd. The patients were examined by an eye specialist. Each patient’s demographic data, type of eyelid malposition, specific treatment results and 6-month follow up of each patient were recorded by the questioners and then were analyzed statistically by SPSS13 software, chi-square and fisher exact test. Results: Among 78 cases, entropion was observed in 41 cases(52.6%, trichiasis in 31 cases(39.7%, ectropion in 27 cases(34.6% and distichiasis in 3 cases (3.8%. The Wies procedure proved to be influential in entropion treatment and lateral tarsal strip canthoplasty surgery also reported acceptable results in ectropion. Conclusion: The involutional changes were the most common causing factors for eyelid malpositions. Entropion appears most prevalently specially in right upper eyelid. The Wies and lateral tarsal strip canthoplasty procedures were thoroughly successful in treatment of entropion and ectropion of either upper or lower eyelids

The aim of this study was to demonstrate the characteristics of sticky eyelid syndrome (SES) and to suggest a modified definition and new classification of the disease in relation to the severity of the syndrome in East Asian patients. Forty-four eyes of 31 patients with sticky eyelid syndrome were included in this study. The medical records of patients who were diagnosed with sticky eyelid syndrome were retrospectively reviewed. Sticky eyelid syndrome was defined as an abnormal adhesion between the upper and lower eyelids during blinking. We divided the subjects into four grades according to the severity of the disease. Among 31 patients, there were 10 men and 21 women. The mean age of patients was 62.5 years. A total of 13 patients had SES bilaterally. All patients had meibomian gland dysfunction (MGD). Thirty-three eyes had dermatochalasis, and 30 eyes had involutional ptosis. Horizontal lower lid laxity was observed in 23 eyes, and reverse ptosis found in 15 eyes. Patients were classified into four groups as follows: G1: 11 (25%), G2: 24 (54.5%), G3: 6 (13.6%) and G4: 3 eyes (6.8%). Patients in Grade 1 tended to improve only with medical treatment for MGD. However, surgical management was necessary for patients in Grades 3 and 4. Meibomian gland dysfunction is a fundamental risk factor for developing sticky eyelid syndrome. Further, combined upper lid ptosis or lower lid laxity may be aggravating factors. According to the grading, medical or surgical management can be chosen. © 2014 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

To investigate the clinicopathologic correlation between horizontal eyelid laxity and extracellular matrix components, such as collagen and elastic fibers, in involutional ectropion and entropion. Another goal was to compare the differences between involutional ectropion and entropion in regard to extracellular matrix content using computer-assisted morphometry. This clinicopathologic study included 20 consecutive patients with involutional ectropion (group 1) and 20 consecutive patients with involutional entropion (group 2). The pinch test was performed to measure horizontal eyelid laxity in both groups. Full-thickness eyelid biopsy specimens were examined by light microscopy and computer-assisted morphometry. The Mann-Whitney U test, the Pearson chi-square test, the Pearson correlation coefficient calculation, and a linear regression analysis were performed. All sections of specimens from patients in groups 1 and 2 revealed abnormal collagen and elastic fibers. The Pearson correlation coefficient revealed a significant negative correlation between horizontal eyelid laxity and extracellular matrix content in the eyelid skin, the pretarsal orbicularis oculi muscle, the perimeibomian tarsal stroma, and the intermeibomian tarsal stroma. Linear regression demonstrated that horizontal eyelid laxity is dependent upon extracellular matrix components in all eyelid regions. Collagen fiber content was significantly increased in specimens from patients in group 1 compared with specimens from patients in group 2. The present findings suggest that a reduction of collagen and elastic fibers may contribute to the development of excessive horizontal eyelid laxity in patients with involutional ectropion and entropion of the lower eyelid.

Full Text Available Background & objectives : The surgery of breast cancer like any other surgeries may bring about some problems and complications, which the knowledge of these problems may be an effective way for prevention or dealing with the complications. The motor and sensory impairments in the upper limb of the surgery side necessitate the utilization of the rehabilitation methods. The main purpose of this research was to show the effect of Pilates exercise on range of motion and edema of upper limb in females suffering from breast cancer after going through surgery.   Methods: This quasi- experimental study was conducted on 25 patients randomly chosen among the patients referring to Cancer Institute. The designed exercise included five "Mat Pilates" moves which were done for 15 sessions until the patient reached fatigue borderlines. Meantime, the control group was doing routine active exercises in physiotherapy center. The range of motion and edema of upper limb was measured before and after applying the designed exercise. For describing the data, the mean and standard deviation, and for inferential analysis, the correlated T-tests and one way analysis of variance were used in level of significance of 5%, to compare the variants before and after applying the designed exercise.   Results: The results showed a significant difference between the flexion, extension, and internal, external rotation of shoulder, flexion and extension of elbow, flexion, extension, supination deviation and pronation deviation of the wrist and forearm before and after experiment in Pilates group. While in the control group, flexion, extension, internal and external rotation of shoulder, flexion and extension of elbow, and flexion of wrist showed a significant difference before and after the experiment.   Conclusion: The use of Pilates exercise after mastectomy surgery can increase the range of motion of the upper limb in the involved side of the patients, and decrease the edema

El 36 % de los pacientes se encontraban en el grupo comprendido entre los 31 y los 50 años de edad, y solo el 6 % eran menores de 15 años. El 64 % de los casos operados correspondieron al sexo femenino. El 41 % de las neoplasias se localizaron en párpado superior y el 40 % en el inferior. Encontramos 16 tipos histológicos de tumores. Los tumores benignos de los párpados son más frecuentes a partir de la tercera década de la vida. Afectan preferentemente al sexo femenino. Se localizan preferentemente en el párpado superior e inferior. Los quistes, seguidos por los nevus y las queratosis fueron los diagnósticos histológicos más frecuentes.A descriptive and retrospective study of 266 medical histories corresponding to patients with histological diagnosis of benign eyelid neoplasias was made. They were operated on at the Oculoplastic Surgery Department of "Pando Ferrer" Ophthalmologic Hospital from January, 1989, to December, 1999. 36 % of the patients were in the group aged 31-50 and only 6 % were under 15. 64 % of the cases that underwent surgery were females. 41 % of the neoplasias were localized in the upper eyelid and 40 % in the lower eyelid. 16 histological types of tumors were found. The benign eyelid tumors are more frequent from the third decade of life on, and females are the most affected. These tumors are localized mainly in the upper and lower eyelid. Cysts, followed by nevus and keratosis were the commonest histologic diagnoses.

to study normal blood and lymph microcirculation of the upper and lower eyelids in different age groups. The study included 108 volunteers (216 eyes) aged from 20 to 80 years with no signs of changes in anterior segment structures, who were grouped by age ranges (20-30 years, 31-40 years, 41-50 years, 51-60 years, 61-70 years, and 71-80 years) into 6 groups equal in gender and quantitative composition. In all volunteers, microcirculation of the upper and lower eyelids was examined by laser Doppler flowmetry (LDF) ('LASMA MC-1' peripheral blood and lymph flow analyzer and 'LASMA MC' laser diagnostic complex, LASMA LLC). The average perfusion changes in blood and lymph flow as well as blood and lymph flow oscillations were analyzed. Blood and lymph flow in the microvasculature of the upper and lower eyelids is variable and depends on neither the age, nor gender of the test subject. On LDF-gram, every increase in amplitude of blood flow corresponds to a decrease in that of lymph flow. The non-invasive method of LDF expands our diagnostic capabilities as it enables assessment of not only blood, but also lymph flow. The data obtained can serve as a starting point for exploring microcirculation in different age groups in the presence of different pathological processes.

Oriental upper blepharoplasty.

Weng, Chau-Jin

2009-02-01

Aesthetic surgery of the upper eyelids is a very common procedure performed in cosmetic practices around the world. The word blepharoplasty, however, has a different meaning in Asia than it does elsewhere. Orientals have different periorbital anatomic characteristics, their motivations for seeking eyelid treatment are different, and operative techniques have been adapted consequently. There are also many eyelid shapes among Orientals, mostly with regard to the presence and location of the supratarsal fold and/or presence of an epicanthal fold. The surgeon must therefore master a range of surgical procedures to treat these variations adequately. It is critical to know the indications for each blepharoplasty technique as well as their complications to select the right surgery and avoid unfavorable results. Epicanthoplasty performed on the right patient can greatly improve aesthetic results while retaining ethnic characteristics. This article will discuss Oriental eyelid characteristics, preoperative patient assessment, commonly used corrective techniques for the "double-eyelid" creation, and complications and how to avoid them.

2017-05-04

Complications associated with gold-weight insertion for lagophthalmos are uncommon, recent reports have provided evidence to suggest that type IV hypersensitivity to gold can cause a persistent inflammatory reaction. We present a case of a 46-year-old man who experienced persistent post-operative inflammation, and summarize previously documented cases. This patient underwent uncomplicated insertion of an upper eyelid gold weight for right-sided facial nerve palsy. He had no allergies or implanted metalwork. Post-operatively erythema was noted at seven-weeks and did not resolve. The weight was removed after six-months. The histopathological findings were in keeping with type IV hypersensitivity and similar to previous cases. Although infrequent, this complication has poor outcomes. The definitive management is removal of the weight. Information regarding implanted gold, and previous reactions should be elicited pre-operatively. Type IV hypersensitivity should be considered in patients with persistent inflammation that do not respond to antibiotic or steroid therapy.

Eyelid sebaceous carcinoma (SC) represents a highly aggressive malignancy. Despite the poor prognosis, genetic alterations as potential molecular targets are not available. KRAS mutation and HER2 gene amplification may be candidates related to their genetic alterations. We examined the HER2 and KRAS alteration status in eyelid SCs and compared it with that in other eyelid tumors. The controversial topics of the human papillomavirus (HPV) and p16 expression were also investigated. HER2 amplification was determined by silver in situ hybridization, while immunohistochemistry was performed to study protein expressions in 14 SCs and controls, including 23 other eyelid malignancies and 14 benign tumors. Peptide nucleic acid-mediated PCR clamping and direct sequencing were used to detect KRAS mutations. HER2 protein overexpression was observed in 85.7% (12/14) of the SCs, of which two-thirds showed HER2 gene amplification. HER2 protein overexpression and HER2 amplification were found more frequently in eyelid SCs than in other eyelid tumors. All SCs harbored wild type KRAS genes. No HPV infections were identified in the SCs. Nevertheless, p16 overexpression was found in 71.4% (10/14) of SCs, irrespective of the status of HPV infection. Furthermore, p16 overexpression in eyelid SCs was also significantly higher than that in other eyelid tumors. HER2 protein overexpression, HER2 gene amplifications, and wild type KRAS genes are common in eyelid SCs. HER2 gene amplification may represent potential therapeutic targets for the treatment of eyelid SCs. Copyright © 2014 Elsevier GmbH. All rights reserved.

2011-02-01

To study the basic eyelid and orbital measurement in the four main ethnic groups of southern Thailand. The basic eyelid and orbital surface anatomy of 101 normal subjects aged 20-40 years old were measured in the four ethnic groups of which the majority of people in southern Thailand belong to: Thai, Chinese, Thai-Malay, and Thai-Chinese. Of the 101 subjects, 51 were male and 50 were female. Each ethnic group had at least 12 normal subjects. Male-female data were analyzed separately and compared between groups. The palpebral fissure heights in Thai, Chinese, Thai-Malay, and Thai-Chinese males were 9.5, 9.0, 10.2 and 9.6 mm respectively, which demonstrated statistically significant differences between Thai-Malay versus Thai, and Thai-Malay versus Chinese. The palpebral fissure lengths were 30.4, 29.8, 30.5 and 30.5 mm, but without statistically significant differences. The marginal reflex distances were 3.2, 2.8, 3.7 and 3.1 mm respectively with a statistically significant difference only between Thai-Malay versus Chinese. The levator functions were 15.2, 15.2, 15.3 and 15.2 mm. The upper lid creases were 7.1, 4.0, 6.6, and 4.4 mm, statistically significantly different in Thai versus Chinese, Thai versus Thai-Chinese and Chinese versus Thai-Malay. The Hertel exophthalmometer measurements were 15.4, 16.3, 16.6 and 15.9 mm without statistically significant differences. The female measurements were overall similar to the male measurements, with some parallel differences between the groups. The eyebrow position in this age group was mostly at and above the orbital rim in both genders and all ethnic groups. An absence of upper lid crease and an epicanthal fold were found in significantly greater numbers in the Chinese group compared to the others, while parallel lid crease was significantly found in greater numbers in the Thai-Malay group than in the others. Different eyelid characteristics in diferent ethnic groups are an important feature to note when planning for

Periocular rejuvenation is the most common aesthetic plastic surgery. The aim of this study was to determine effects of micropunch blepharopeeling (MBP) approach vs blepharoplasty (BP) in periocular rejuvenation. This is a clinical trial study on 22 patients who underwent periorbital rejuvenation referred to University Skin Clinics. Patients were randomly divided into two groups of blepharoplasty or micropunch blepharopeeling. After procedure, all patients were followed in 2 weeks and 2 months and were asked about complications. Patients' satisfaction was scored based on 5-grade scale. Physician satisfaction was assessed based on patients' photographs taken before and 2 months after surgery based on 4-grade scale. The mean age of group MBP was 48.45 ± 7.71 and group BP was 45.45 ± 7.20 (P-value = .36) and Fitzpatrick skin type was not significantly different. Scar was significantly different between groups that 4 (36.4%) patients of BP complained from scars, while none of MBP had significant scar (P-value = .04). Patients were statistically more satisfied with MBP in terms of symmetry, pain, and scar (P-value = .048, .040, and<.001, respectively). Also, MBP was significantly more satisfying for physicians in terms of symmetry and scar (P-value = .047 and <.001, respectively). Micropunch blepharopeeling can be considered as an acceptable procedure of upper eyelid rejuvenation mentioned by patients and physicians. Micropunch blepharopeeling causes fewer scars, better symmetry, and less pain. © 2018 Wiley Periodicals, Inc.

Full Text Available Rania El Essawy,1 Rasha Essameldin Galal21Department of Ophthalmology, 2Department of Pediatrics, Faculty of Medicine, Cairo University, Cairo, EgyptBackground: The purpose of this study was to evaluate the results and complications of early surgical resection of large amblyogenic subdermal eyelid hemangiomas in infants after prior short-term parenteral administration of corticosteroids.Methods: Sixteen infants were given dexamethasone 2 mg/kg/day in two divided doses for three consecutive days prior to scheduled surgical excision of large eyelid hemangiomas. The lesions were accessed via an upper eyelid crease, subeyebrow incision, or a lower eyelid subciliary incision.Results: In all cases, surgical excision of the entire lesion was possible with no significant intraoperative or postoperative complications. The levator muscle/aponeurosis complex was involved in 31.25% of cases and was managed by reinsertion or repositioning without resection. A satisfactory lid position and contour with immediate clearing of the visual axis was achieved in all but one case (93.8%.Conclusion: Parenteral corticosteroids helped in reducing volume and blood flow from the hemangiomas, allowing for very early total excision of large subdermal infantile hemangiomas without significant intraoperative hemorrhage. This resulted in immediate elimination of any reason for occlusion amblyopia. Long-term follow-up of visual development in these patients would help to demonstrate the effectiveness of this strategy compared with more conservative measures.Keywords: large eyelid hemangiomas, early surgical resection, parenteral corticosteroids

Monopolar radiofrequency treatment of the eyelids: a safety evaluation.

Biesman, Brian S; Pope, Karl

2007-07-01

Monopolar radiofrequency (RF) energy has been used to successfully accomplish noninvasive skin tightening of the face, abdomen, and extremities. Owing to concerns about injury to the eye itself, monopolar RF treatment of the eyelids has not been feasible. The objective was to evaluate the safety of a novel 0.25-cm(2)"shallow" treatment tip for noninvasive tightening of eyelid skin. This was a tripartite study that began with an animal model to evaluate soft tissue effects and temperature change at the ocular surface. Findings were then extrapolated to ex vivo evaluation of human eyelids and ultimately to an in vivo human eyelid safety study. The animal studies demonstrated that the 0.25-cm(2) treatment tip could be used safely on eyelids in conjunction with appropriate ocular protection. The ex vivo human eyelid studies confirmed that, at typical treatment settings, the shallow treatment tip did not produce frank eyelid injury. The in vivo human studies confirmed that, at the tested settings, the novel treatment tip did not injure the eyelids or eyes. If used properly, the 0.25-cm(2) treatment tip can be safely used on human eyelids.

Allergic contact dermatitis is considered one of the most common causes of eyelid dermatitis. In addition to metals and topical antibiotics, fragrances have emerged as a leading source of contact allergy for individuals with this condition. The objective of this study was to determine the added benefit of including a fragrance tray when patch testing patients presenting with eyelid dermatitis. During a 4.5-year period, all patients with suspected allergic contact dermatitis involving the eyelids were patch tested with both standard and fragrance trays. One hundred consecutive patients with eyelid dermatitis were patch tested. Of these patients, 42 (42%) tested positive for 1 or more allergens within the fragrance series. Of these patients, 15 (36%) had no fragrance markers detected on the standard series, and these allergens would therefore have been missed had fragrance series testing not been performed. Overall, fragrance markers within the standard series detected 73.2% (41/56) of cases of fragrance allergy. Our results suggest that there may be a significant benefit to fragrance series testing in patients with eyelid dermatitis. Fragrance tray inclusion in this population may identify additional cases of fragrance allergy that are missed by the standard series.

Garcia, Giancarlo A; Nguyen, Christine V; Yonkers, Marc A; Tao, Jeremiah P

Baby shampoo is used as an alternative surgical skin preparation, but the evidence supporting its use is scarce with no descriptions of efficacy in the periocular region. The authors compare the efficacy of baby shampoo, povidone-iodine (PI, Betadine) and isopropyl alcohol (IA) in reducing eyelid skin bacterial load. Prospective, randomized, comparative, and interventional trial. Bacterial load on adult, human eyelid skin was quantitated before and after cleansing with 1) dilute baby shampoo, 2) 10% PI, or 3) 70% IA. Paired skin swabs were collected from a 1 cm area of the upper eyelid of subjects before and after a standardized surgical scrub technique. Samples were cultured on 5% sheep blood agar for 24 hours. The number of colony forming units (CFU) was assessed and bacterial load per square centimeter of eyelid skin was quantified. Baseline and postcleansing samples were assessed from 42 eyelids of 42 subjects (n = 14 for each of baby shampoo, PI, and IA). Before cleansing, similar amounts of bacterial flora were grown from all specimens (median log CFU/cm = 2.04 before baby shampoo, 2.01 before PI, 2.11 before IA; p > 0.05). All 3 cleansing agents significantly reduced the bacterial load (p shampoo, 0.39 after PI, 0.59 after IA; p > 0.05). Change from baseline in bacterial load was statistically similar for all 3 agents (median reduction in log CFU/cm = 1.28 with baby shampoo, 1.57 with PI, 1.40 with IA; p > 0.05). These corresponded to bacterial load reductions of 96.3%, 96.6%, and 98.4% for baby shampoo, PI, and IA, respectively. Baby shampoo achieved comparable diminution in eyelid skin bacterial load to PI or IA. These data suggest baby shampoo may be an effective preoperative cleansing agent.

A 16-year-old boy developed over a 2-month interval a lightly pigmented left upper eyelid lesion measuring 1.5 mm in greatest diameter that, when excised, microscopically was hypercellular and composed almost exclusively of nonpigmented epithelioid cells that created florid, large intraepidermal junctional nests and sheets and nests of subepidermal cells. The diagnosis was a Spitz nevus. HMB-45, MART-1, and microphthalmia-associated transcription factor were all positive and established the melanocytic nature of the benign tumor. The Ki-67 proliferation index (5%) and 2 mitoses/mm(2) were both low; p16 protein was immunohistochemically identified in the nevoid cells. We review the clinical, histopathologic, and other immunohistochemical features of this entity and provide a brief differential diagnosis (including separation from a Spitzoid melanoma). This is only the third eyelid Spitz nevus reported in the literature and is the most fully characterized immunohistochemically. At their present stage of development, contemporary immunohistochemical biomarkers, while providing supplemental information, nonetheless remain less than definitive in terms of reliably distinguishing benign from malignant Spitz lesions.

Despite the fact that the majority of eyelid tumors are benign, proper management in daily practice requires detection of the malignant ones. Several clinical criteria are usually proposed to support or reject a hypothesis of malignancy; however, most are of limited reliability. In any case of doubt, outpatient biopsy is recommended, so as to establish the correct diagnosis and formulate the most appropriate treatment plan. In all facial malignancies, the first (and absolutely mandatory) consideration is control of the cancer. Then, restoration of eyelid function can be addressed, in the following order: protection of the globe by complete dynamic eyelid closure and opening, visual function (and prevention of possible deprivation amblyopia) by insuring a clear visual axis, correction of the tear film, efficient lachrymal drainage, and only then the role of the eyelids in facial expression and esthetics. For most malignant eyelid tumors, the best assurance of complete excision is obtained by extemporaneous examination of the resection margins by frozen section (by Mohs' micrographic surgery techniques, or a variation thereof). Currently, advancement and transposition flaps, possibly in combination with tarso-conjunctival or skin grafts, are the most utilised techniques. Despite the lack of histological verification, new treatment modalities, including topical chemotherapy, photodynamic therapy and cryotherapy, may provide interesting treatment options, particularly in collaboration with the dermatologist.

Full Text Available Aim: To observe the incidence of full or partial eyelid closure at death. Materials and Methods: The presence of ptosis was recorded in 100 consecutive hospice patient deaths. Results: Majority (63% of the patients died with their eyes fully closed, however, 37% had bilateral ptosis at death, with incomplete eye closure. In this study, central nervous system tumor involvement and/or acute hepatic encephalopathy appeared to be pre-mortem risk factors of bilateral ptosis at death. Conclusion: Organicity and not psychogenicity is, therefore, the likely etiology of failure of full eyelid closure at death.

Some studies on radiotherapy for eyelid cancer have been reported, but the optimal radiation doses for different histological types and tumor sizes have not been detailed. So I studied the optimal radiation doses in radiotherapy for eyelid cancer. The patients were fourteen and histological diagnoses were made on the basis of biopsies or surgery before radiotherapy. Surgical cut margins were positive in 10 cases. In 5 of these cases, tumors were visible. There were 9 sebaceous adenocarcinomas (SAC), 4 squamous cell carcinomas (SCC), and 1 basal cell carcinoma (BCC). In 13 of 14 cases, radiation was applied to eyelids in which tumor-surgical cut margin distances were 3 mm or less. The eyeballs were covered with lead or tungsten shields, and the eyelids were irradiated with a total dose of 50 to 66.6 Gy. In 5 cases, radiation was applied prophylactically for ipsilateral pre-auricle lymph node areas. 11 of 13 cases were locally controlled. I gave greater radiation doses for SAC than for SCC or BCC. I also gave greater doses for in visible tumors than for invisible ones. In the acute phase dermatitis, inflammation of the cornea, conjunctivitis, etc. occurred but they were mild. Later reactions were decreased cilia, dry eye, inflammation of cornea, conjunctivitis, discomfort of the scar, etc. Cataracts were also seen, but they were of senile origen. Because 81.8% of the tumors were controlled, this radiation method was useful with salvage therapies to select an optimal radiation dose according to the differences among histological types and tumor sizes. 60% of visible tumors were also controlled so I think that radical therapy using radiation alone is possible.

The utility of impression cytology in ocular diseases has predominantly been restricted to the diagnosis of dry eye, limbal stem cell deficiency and conjunctival neoplasias. Its role in malignant eyelid lesions remains largely unexplored. Although scrape cytology is more popular for cutaneous lesions, impression cytology, being non-traumatic, has an advantage in small and delicate areas such as the eyelid. The present study has been designed to evaluate its role in the diagnosis and management of malignant eyelid lesions. Thirty-two histopathologically proven malignant eyelid lesions diagnosed over a 2-year period, including 13 basal cell carcinomas, 11 sebaceous carcinomas, four squamous cell carcinomas, two malignant melanomas and two poorly differentiated carcinomas, formed the study group. The results of impression cytology were compared with those of histopathology in the study group and with an age- and sex-matched group of benign cases as controls. The sensitivity of impression cytology was 84% (27/32) for the diagnosis of malignancy and 28% (9/32) for categorization of the type of malignancy. Impression cytology is a simple, useful, non-invasive technique for the detection of malignant ulcerative eyelid lesions. It is especially useful as a follow-up technique for the detection of recurrences. © 2014 John Wiley & Sons Ltd.

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

Anthrax is a disease caused by Bacillus anthracis. The disease affects primarily herbivores including sheep, cattle, horses, and other domestic animals. Humans may rarely be affected. We examined one male and two female patients with a localised itchy erythematous papule of the eyelid. A necrotising ulcer formed in each of the three cases resulting in a black lesion. Scraping in each case showed Gram positive rods and culture grew Bacillus anthracis. All three patients responded to the intravenous administration of penicillin G, and the lesion resolved leaving scars in two cases. Anthrax is a rare disease but should be considered in the differential diagnosis of ulcers or pustules of the eyelids. Images PMID:1486081

2007-01-01

Full Text Available Background: Eyelid malignancies are completely treatable if detected early. The treatment depends on the invasiveness of the cancer which in turn depends on the type of malignancy. Aim: The aim of the study was to characterize the distribution of the types of eyelid malignancies in central India. Settings and Design: The study was conducted in the Department of Plastic and Maxillofacial Surgery at a tertiary care hospital. Materials and Methods: We report a series of 27 cases of eyelid malignancies. In the same case series, we also include a case of malignant hemangiopericytoma which is an extremely rare form of eyelid malignancy worldwide. Statistical Analysis: Depending on the underlying statistical distribution, either analysis of variance (ANOVA or the Kruskal-Wallis (K-W test was used to assess the differential distribution of these variables across the types of eyelid malignancies observed in this study. Results: We observed that sebaceous cell carcinoma (~37% was almost as prevalent as basal cell carcinoma (~44% in the study subjects and had an earlier age of occurrence and a more rapid clinical course. Conclusions: Sebaceous cell carcinoma of the eyelid is almost as common as basal cell carcinoma in a large tertiary care centre in central India.

Objective: To analyse the demography, mode of presentation, gross morphology, histopathological diagnosis and subsequent course of malignant eyelid tumours in north-west Pakistan. Methods: The retrospective observational study was performed at the Department of Ophthalmology, Khyber Teaching Hospital, Peshawar, from January 2007 to July 2010, and comprised data related to 222 patients. Charts of patients with malignant eyelid tumours admitted to the department during study period were reviewed. Patients' demographic data, gross and microscopic features of the tumours and their subsequent course of treatments were recorded. SPSS 14 was used for statistical analysis. Results: Of the total, 122 (54.1%) patients were male and 102 (45.9%) were female. Mean age of all patients was 59.3+-14.2 years. Among the patients, 73 (32.9%) had the involvement of the lower lid; 57 (25.7%) the upper lid; 18 (8.11%) the medial canthus; 2 (0.9%) the lateral canthus; and 72 (32.4%) had more than one region involved. On histopathology, basal cell carcinoma was the most common (n= 131; 59%), followed by squamous cell carcinoma in 70 (31.5%), sebaceous gland carcinoma in 15 (6.8%), malignant melanoma in 3 (1.3%) and undifferentiated carcinoma in 3 (1.3%) cases. Of the total tumours, 164 (73.87%) did not spread, and 58 (26.13%) spread either locally or distantly. Conclusion: Basal cell carcinoma was is the most common malignant eyelid tumour in the study. Squamous cell carcinoma, which was second, was found to be more common in north-west Pakistan than in any other part of Asia, while the sebaceous gland carcinoma was relatively less common. (author)

Full Text Available Eversion of the third eyelid - EPT, is a condition when the third eyelid rolls back, actually of its margin anteriorally. It occurs almost exclusively in big dog breeds such as the German shepherd, doga, St. Bernard, Newfoundalnder, retrievers, and English bulldogs. Congenital or acquired weakness of the PT cartilage is considered as the main reason for the incidence of EPT. The clinical picture is diverse and it most often depends on the intensity, duration and possible complications. The most prominent sign is a certain degree of EPT. Therapy is based on careful submucous excision of the deformed cartilage, with optional stitching of the conjunctive. The most frequent complication is a repeated eversion of the eyelid, as well as protrusion of the PT gland. The prognosis is good if the preoperative and operative procedure are carried out as required, and the eyelid is not too long. .

2015-03-01

Full Text Available INTRODUCTION: Congenital eversion of the eyelids, a condition usually seen shortly after birth is a rare condition affecting one or both eyelids of the eye. Many etiologies have been described but no specific cause has been identified. We report a case of congenital eve rsion of eyelids which was managed conservatively with spontaneous correction seen in 6 days. KEYMESSAGE: Congenital eversion of the eyelids is a rare easily identifiable and potentially treatable condition. Decision of surgical intervention has to be take n with care and must be individualized for each case. Congenital eversion must be differentiated from congenital ectropion due to causes like ichthyosis as the treatment widely differs. All ophthalmologists need to be aware of this condition as it can be e asily managed on an outpatient basis

Eyelid Dermatitis: Contact Allergy to 3-(Dimethylamino)propylamine

Science.gov (United States)

Knopp, Eleanor; Watsky, Kalman

2014-01-01

We present the case of a 42-year-old woman with intractable eyelid dermatitis. Patch testing revealed sensitization to 3-(dimethylamino)propylamine (DMAPA). DMAPA is an important etiology of allergic contact dermatitis of the eyelids and face but is easily missed even with expanded-series patch testing. We also review the most common causative allergens in eyelid dermatitis cited in the literature over the past decade. DMAPA is a reagent used in the formation of cocamidopropyl betaine (CAPB), a common additive to liquid soaps, shampoos, and other cleansing products because of its utility as a surfactant. Beginning in the 1980s, reports of allergy to CAPB surfaced in the literature. Ultimately, a majority of patch testing studies have shown that clinical allergy to CAPB-containing products actually reflects allergy to contaminant DMAPA in most cases. Amidoamine, another intermediate in the formation of CAPB, may also be implicated through a proposed mechanism of conversion to DMAPA in the skin. When patch-testing for eyelid and facial dermatitis, it is crucial to test with DMAPA directly, not just with CAPB; unlike commercial-grade CAPB, the CAPB in patch test kits is ultrapure and does not contain contaminant DMAPA.

Ameli, F; Phang, K S; Masir, N

2011-12-01

Churg-Strauss syndrome, a small and medium vessel vasculitis, was first described by Churg and Strauss in 1951. It is characterised by the presence of asthma, prominent tissue and blood eosinophilia, systemic vasculitis, and pulmonary and systemic necrotising allergic granulomas. Involvement of the skin, heart and gastrointestinal tract is well documented, but ocular presentation is unusual. We describe a 40-year-old lady who presented with recurrent upper eyelid swelling due to conjunctival lesions. Although she has chronic asthma, Churg-Strauss syndrome was never suspected. The diagnosis of Churg-Strauss syndrome was only made following histological examination of the conjunctival lesions.

The recent finding of negative thyrotropin receptor (TSHR antibodies, as measured in the ­Thyretain™ thyroid-stimulating immunoglobulin (TSI reporter bioassay, in patients with euthyroid Graves’ disease raises the possibility that TSHR antibodies are not the cause of ophthalmopathy in all situations. Here, we have tested serum from patients with HT with and without ophthalmopathy or isolated upper eyelid retraction (UER for TSHR antibodies, using the TSI reporter bioassay and collagen XIII as a marker of autoimmunity against the orbital fibroblast. Study groups were 23 patients with HT with ophthalmopathy, isolated UER, or both eye features and 17 patients without eye signs. Thyretain™ TSI results were expressed as a percentage of the sample-to-reference ratio, with a positive test being taken as a sample-to-reference ratio of more than 140%. Serum collagen XIII antibodies were measured in standard enzyme-linked immunosorbent assay. TSI tests were positive in 22% of patients with HT with no eye signs but in no patient with eye signs. In contrast, TSI tests were positive in 94% of patients with Graves’ ophthalmopathy. Tests were negative in all normal subjects tested. Collagen XIII antibodies were detected in 83% of patients with ophthalmopathy, UER, or both eye features, but in only 30% of patients with no eye signs. Our findings suggest that TSHR antibodies do not play a major role in the pathogenesis of ophthalmopathy or isolated UER in patients with HT.

To determine computed tomographic (CT) imaging characteristics of retropharygeal edema, we reviewed CT images in 18 patients with head and neck tumors. Retropharyngeal edema spread craniocaudally between soft palate and upper half of thyroid cartilage in all patients. No edema fluid extended above soft palate and below thyroid cartilage. Horizontally, it spread symmetrically in ten and asymmetrically in eight patients. Predominance in asymmetrical retropharyngeal edema was found on the same side as that of unilateral predominance both in lymph nodes enlargement and jugular vein stenosis/occlusion. All patients had edema also in other cervical spaces. Edema of retropharyngeal and other spaces fluctuated synchronously. In 14 patients, as primary lesion and/or cervical lymph nodes regressed, retropharyngeal edema disappeared or decreased. Retropharyngeal edema had some imaging characteristics. With knowledge of that, we could avoid diagnostic confusion when evaluating head and neck CT images. (orig.)

RESULTS:(1The clinically total effective rate was 74% of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups(PPPPCONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation; partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

The feasibility of topical application onto the (lower) eyelid skin to deliver hydrophilic and lipophilic compounds into the conjunctiva and ocular tissues was evaluated by comparing with conventional eye drop application. Skin permeation and the concentration of several model compounds, and skin impedance were determined utilizing eyelid skin from hairless rats, as well as abdominal skin in the same animals for comparison. In vitro static diffusion cells were used to assess the skin permeation in order to provide key insights into the relationship between the skin sites and drugs. The obtained results revealed that drug permeation through the eyelid skin was much higher than that through abdominal skin regardless of the drug lipophilicity. Specifically, diclofenac sodium salt and tranilast exhibited approximately 6-fold and 11-fold higher permeability coefficients, respectively, through eyelid skin compared with abdominal skin. Histomorphological evaluation and in vivo distribution of model fluorescent dyes were also examined in the conjunctiva and skin after eyelid administration by conventional microscope and confocal laser scanning microscope analyses. The result revealed that eyelid skin has a thinner stratum corneum, thereby showing lower impedance, which could be the reason for the higher drug permeation through eyelid skin. Comparative evaluation of lipophilic and hydrophilic model compounds administered via the eyelid skin over 8h revealed stronger fluorescence intensity in the skin and surrounding tissues compared with eye drop administration. These results suggested that the (lower) eyelid skin is valuable as a prospective site for ophthalmic medicines. Copyright © 2017 Elsevier B.V. All rights reserved.

Focal frontal epileptiform discharges in a patient with eyelid myoclonia and absence seizures

Full Text Available Eyelid myoclonia with absences is classified as a unique type of generalized seizure. Its pathogenesis is proposed to involve the functional abnormalities in cortical–subcortical networks. Here, we describe the case of a 7-year-old boy who had eyelid myoclonia with absences, along with focal motor seizures. Video-EEG monitoring demonstrated eyelid myoclonia associated with 4- to 5-Hz generalized polyspike–waves preceded by focal frontal discharges. Interictal EEG showed focal epileptiform discharges over the frontal regions. Our case suggests an important role of the frontal lobe in the generation of eyelid myoclonia with absences.

A gene prenature ovarian failure associated with eyelid malformation maps to chromosomes 3q22-q23

Premature ovarian failure and XX gonadal dysgenesis leading to female infertility have been reported in association with an autosomal dominantly inherited malformation of the eyelids: blepharophimosis-ptosis-epicanthus inversus syndrome (BPES; MIM 110100). This association distinguishes BPES type I from BPES type II, in which affected females are fertile and the transmission occurs through both sexes. Recently, a gene responsible for BPES type II has been mapped to chromosome 3q22-q23, and the critical region for the gene location has been reduced to the interval between loci D3S1615 and D3S1316. Hitherto, however, no information regarding the localization of the gene for BPES type I, in which female ovarian failure is associated with eyelid malformation, has been available. We have studied two independent families affected with BPES type I, including a total of 12 affected individuals (6 infertile women) and 6 healthy relatives. The diagnostic criteria for the ophthalmological anomaly included (1) reduced horizontal diameter of palpebral fissures, (2) drooping of the upper eyelids, and (3) an abnormal skinfold running from the lower lids. Telecanthus and a flat nasal bridge were present in most cases. In both families the disease was transmitted only by the male, and no affected woman of childbearing age was fertile. 12 refs., 2 figs., 1 tab.

Pathogenesis of Brain Edema and Investigation into Anti-Edema Drugs

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. PMID:25941935

Merkel cell carcinoma (MCC) in the eyelid and periocular region can be treated surgically, in most cases, with preservation of the eye and reasonable visual function. Adjuvant radiation therapy, sentinel lymph node biopsy, and chemotherapy should be considered for MCC of the eyelid and periocular region, especially for larger tumors that are T2b or more advanced and lesions that present with regional nodal or distant metastasis.

Full Text Available Reconstruction of the eyelids after skin cancer excision can be challenging. Surgical treatment options are multiple; deep anatomy knowledge of lamellar components is mandatory to choose the most adequate surgical planning. Eyelids’ role in vision and social relationship is critical; both function and aesthetics are tough to restore. Using a flap provides a satisfying texture and colour match with adjacent tissues and ensures short contraction during healing; furthermore, grafts are sometimes necessary to achieve pleasing results. Hundreds of surgical techniques have been described aiming for eyelid reconstruction; in our paper, we want to provide for our audience the most reliable and useful procedures for subtotal and total eyelid reconstruction following NMSC full-thickness excision.

ventilatorio con PEEP o CPAP, no necesitando de cualquier otra terapia. El pronóstico es bueno, con mejoría en la mayoría de los casos en las primeras 24 horas.BACKGROUND AND OBJECTIVES: 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. CASE REPORT: 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. CONCLUSIONS: 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

Primary Intestinal Lymphangiectasia Manifested as Unusual Edemas and Effusions

2016-01-01

Abstract Primary intestinal lymphangiectasia (PIL) is a rare disorder of unknown etiology characterized by diffuse or localized dilation and eventual rupture of the enteric lymphatic vessels in mucosa, submucosa, and/or subserosa. Lymph, rich in all kinds of proteins and lymphocytes, leaks into the gastrointestinal tract via the affected lymphatic vessels causing hypoproteinemia and lymphopenia. The main symptom is variable degrees of pitting edemas of bilateral lower limbs. But edemas of any other parts of body, and mild serous effusions may also occur sometimes. PIL occurs in conjunction with a right hemifacial edema, a right upper limb lymphedema, asymmetric bilateral calves edemas, and a unilateral massive pleural effusion seems never to be reported before. In addition, increased enteric protein loss that may cause severe hypoproteinemia usually get overlooked, and the lymphatic system disorders always put the diagnoses in a dilemma. We described a case of a 17-year-old Chinese girl with a history of gradually progressive swellings of right-sided face, right upper limb, and bilateral calves since 3 to 4 months of age. A right-sided massive pleural effusion, a moderate pericardial effusion, and a mild ascites have been proved unchanged by a series of computerized tomography (CT) scans since 5 years ago. The diagnosis of PIL was finally confirmed by severe hypoproteinemia, endoscopic changes, and histology of jejunum biopsy. Further lymphoscintigraphy and lymphangiography also identified lymph leakage in her bowel and several abnormal lymphatic vessels. A high-protein, low-fat diet supplemented with medium-chain triglycerides (MCT) showed some benefit. This case suggested that PIL was a rare but important etiology of hypoproteinemia, effusions, and edemas. PIL, effusions, and lymphedema can be the features of multisegmental generalized lymphatic dysplasia. In addition, both lymphoscintigraphy and intranodal lymphangiography could be considered when lymphatic

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.

Background and purpose: Surgical excision remains the standard and most reliable curative treatment for eyelid carcinoma, but frequently causes functional and cosmetic impairment of the eyelid. We therefore investigated the efficacy and safety of radiation therapy in eyelid carcinoma. Patients and methods: Twenty-three patients with primary carcinoma of the eyelid underwent radiation therapy. Sebaceous carcinoma was histologically confirmed in 16 patients, squamous cell carcinoma in 6, and basal cell carcinoma in 1. A total dose of 50-66.6 Gy (median, 60 Gy) was delivered to tumor sites in 18-37 fractions (median, 30 fractions). Results: All but 3 of the 23 patients had survived at a median follow-up period of 49 months. The overall survival and local progression-free rates were 87% and 93% at 2 years, and 80% and 93% at 5 years, respectively. Although radiation-induced cataracts developed in 3 patients, visual acuity in the other patients was relatively well preserved. There were no other therapy-related toxicities of grade 3 or greater. Conclusion: Radiation therapy is safe and effective for patients with primary carcinoma of the eyelid. It appears to contribute to prolonged survival as a result of good tumor control, and it also facilitates functional and cosmetic preservation of the eyelid. (orig.)

Possible physiological role of milk epidermal growth factor in neonatal eyelid opening

The eyelid opening of newborn mice occurs normally on day 13.9 +/- 1.8 after birth. When newborn mice were injected with anti-epidermal growth factor (EGF) antibody every other day starting on day 1 after birth, the eyelid opening was delayed by ∼ 3 days. The effect of anti-EGF became less prominent as the treatment was started at later times: when it was give from day 7, no delay in eyelid opening was observed. On the other hand, eyelid opening was enhanced by ∼ 3 days by EGF injection given on day 3 for every other day. This effect of EGF was antagonized by simultaneous administration of anti-EGF antibody. EGF was present at a concentration of 6.6 ng/ml in the plasma of 1-wk-old pups nursed by their mother, but it was not detectable in the plasma of 3-wk-old weaned pups. EGF concentration in the submandibular glands, however, was 17 times greater in 3- than in 1-wk-old pups. EGF was measured by radioimmunoassay. These results suggest that milk EGF may play a physiological role in eyelid opening during the neonatal period

A 16-year-old African American male, the youngest patient to date, presented with a well-circumscribed upper eyelid lesion. On excision, the dermal nodule was contiguous with the epidermis, displayed trichohyalin-like bodies in an expanded outer root sheath, and was composed chiefly of small cellular clusters separated by a prominent network of periodic acid Schiff -positive hyaline bands of basement membrane material. The tumor cells were positive for high molecular weight cytokeratins (CK) 5/6, CK14, and CK34βE12 and were negative for CK7, carcinoembryonic antigen and epithelial membrane antigen. Negative S100, glial fibrillary acidic protein, and smooth muscle actin immunoreactions ruled out a myoepithelial lesion. The Ki-67 proliferation index was <10%. The diagnosis was a hyalinized trichilemmoma, contrasting with the more common lobular type. As an isolated lesion, trichilemmoma does not portend Cowden syndrome.

Edema in palliative care patients is a common symptom, however, the research base for all aspects of its care is extremely poor. To evaluate a specialist palliative care edema service in order to report on the patient population referred, the types of edema encountered, and the causes of edema. Prior to study, three different edema types were described for evaluation: lymphedema, nonlymphatic edema, and a combination of the two. Retrospective chart evaluation was completed from August 2013 through January 2014. Patients with edema assessed by the specialist palliative care physiotherapy edema service. Sixty-three cases were included, comprising 10.5% of all new palliative care referrals during the study period. Ninety-two percent (n = 58) had a diagnosis of cancer and 57% (n = 36) were female. Age ranged from 45-97 years. The most common edema type was a mixed edema (46%, n = 29), followed by lymphedema (27%, n = 18) and nonlymphatic edema (16%, n = 10). Lymphorrhea occurred in 9.5% of cases. The most common reasons for edema, based on clinical opinion, were blocked lymphatics (33%) and dependency from immobility (27%). The most common site for edema was in the lower limbs (89%, n = 56). The time lapse from the last treatment to death ranged from 1-225 days. Having a mixed edema type or lymphorrhea was a relatively poor prognostic sign. This is the first study to describe in detail the occurrence of edema in palliative care patients. Edema may be present for many months prior to death making the search for effective treatments imperative.

We experienced a case of negative pressure pulmonary edema after tracheal extubation following reversal of rocuronium-induced neuromuscular blockade by sugammadex. In this case, the contribution of residual muscular block on the upper airway muscle as well as large inspiratory forces created by the respiratory muscle which has a low response to muscle relaxants, is suspected as the cause.

Sporotrichosis is a common subcutaneous mycosis caused by an infection with dimorphic fungus Sporothrix schenckii. We present a series of patients with eyelid sporotrichosis and study the clinical and histopathological presentation, microbiology, treatment options, and outcome. A retrospective case-series study of patients with a clinical diagnosis of eyelid sporotrichosis. Records were examined to obtain information regarding patient demographics, presenting symptoms and signs, histopathological examination, microbiology, management, and outcomes. Ten patients (4 men, 6 women; mean age 46.5 years, range 3-81 years) were included. Based on their clinical manifestations, eyelid sporotrichosis was classified into 3 major forms: (i) fixed cutaneous (6/10 cases), (ii) lymphocutaneous (3/10 cases), and (iii) eyelid abscess (1/10 cases). All the cases were treated with a terbinafine 12-week regimen. Nodules, papules, and abscesses regressed after treatment. No recurrence was discovered after a 12-week follow-up. Eyelid sporotrichosis has typical features of clinical manifestations. Histopathological examination and tissue culture are helpful for diagnosis. Confirmed cases normally require long-term systematic treatment with antifungal agents, but surgical removal is normally unnecessary. Copyright © 2016 Canadian Ophthalmological Society.

Full Text Available Lower eyelid reconstruction after tumor resection or trauma is extremely important in order to obtain the protection of the globe and it requires extra care. The aim of this study is to evaluate the techniques that we use in lower eyelid reconstruction. Between the years of 1999-2009, a total of 23 patients who had lower eyelid defects due to tumor resection (21 patients or trauma (2 patients were reconstructed by the use of various flaps. Eleven of the patients were women and twelve of them were men. Average age was 60.7.

Hearing of eyeball movements has been reported in superior semicircular canal dehiscence (SSCD), but not hearing of eyelid movements. Our main objective was to report the hearing of eyeball and/or eyelid movements in unilateral SSCD. Our secondary objective was to access its specificity to SSCD and discuss the underlying mechanism. Six patients with SSCD who could hear their eyeball and/or eyelid movements were retrospectively reviewed. With the aim of comparisons, eight patients with an enlarged vestibular aqueduct (EVA), who share the same mechanism of an abnormal third window, were questioned on their ability to hear their eyeball and/or eyelid movements. Three patients with SSCD could hear both their eyeball and eyelid movements as a soft low-pitch friction sound. Two patients with SSCD could hear only their eyelid movements, one of whom after the surgery of a traumatic chronic subdural hematoma. The latter remarked that every gently tapping on the skin covering the burr-hole was heard in his dehiscent ear as the sound produced when banging on a drum, in keeping with a direct transmission of the sound to the inner ear via the cerebrospinal fluid. One patient with SSCD, who could hear only his eyeball movements, had other disabling symptoms deserving operation through a middle fossa approach with an immediate relief of his symptoms. None of the eight patients with EVA could hear his/her eyeball or eyelid movements. Hearing of eyeball and/or eyelid movements is highly suggestive of a SSCD and do not seem to occur in EVA. In case of radiological SSCD, clinicians should search for hearing of eyeball and/or eyelid movements providing arguments for a symptomatic dehiscence. The underlying mechanism is discussed particularly the role of a cerebrospinal fluid transmission.

Full Text Available O entrópio congênito primário da pálpebra superior é mais raro que o da pálpebra inferior. O diagnóstico no neonato, apesar de ser difícil, é imprescindível. O seu reconhecimento precoce exige a correção cirúrgica imediata, pois essa é uma condição que não melhora espontaneamente, podendo levar a úlceras de córnea com nefastas conseqüências para a visão. Várias técnicas cirúrgicas têm sido descritas para correção da deformidade. Na análise e comparação dos dados do pré, per e pós-operatório do presente caso com os descritos na literatura, é enfatizada a importância da retração da lamela posterior da pálpebra no mecanismo etiopatogênico. Com o tempo de seguimento de 34 meses, os autores apresentam o resultado e descrevem o procedimento realizado, que consistiu no deslocamento do músculo orbicular pré-tarsal e da aponeurose do músculo elevador da pálpebra superior para a área pré-septal após terem sido desinseridos da face anterior do tarso.The primary congenital entropion of the superior eyelid is more infrequent than the one of the inferior eyelid. The premature diagnosis of this deformity in newborns, although difficult, is very necessary because implies an immediate surgical correction as it is a condition that does not recover spontaneously even leading to corneal ulceration with disastrous consequences for the vision. Many surgical techniques have been described to correct this malformation. The analysis and confrontation of the pre, per and postoperative data of the current case with the ones present in the literature emphasizes the importance of the retraction of the eyelid's posterior lamella in the etiopathogenesis mechanism. With the follow-up period of 34 months the authors present the results and describe the procedure taken, which consisted in the transplantation of the pretarsal orbicular muscle and of the aponeurosis of the levator muscle for the preseptal region after being removed

The next three articles in this issue take a unique approach to discussing volumetric restoration. Robert Glasgold has provided an assessment for each facial region and five different renowned authors (TK, SPS, RF, SML, and EFW) have been asked to speak on a particular volumetric product, of which they are considered an expert, as it applies to the different regions of the face. The articles are broken into the following: (1) upper third which corresponds to the upper eyelid, brow, temple, and forehead; (2) middle third which will cover lower eyelid, cheek, and perioral area; and (3) lower third which discusses the marionette, prejowl, and jawline. Our hope is that by placing differing opinions of experienced authors, organized by facial region together, the reader will have the opportunity to more readily compare the options. The contributing authors and their product area are as follows: Theda Kontis, MD-hyaluronic acid; Steve Smith, MD-calcium hydroxyl appetite; Rebecca Fitzgerald, MD-poly-L lactic acid; Sam Lam, MD-polymethyl methacrylate; and Edwin Williams, MD-Autologous Fat Transfer. If the author included general comments on the product, they are included in the article on the upper face only and are not repeated. Please note that other individuals may also have significantly assisted in the production of these articles, but those listed above are the senior authors.

Primary Intestinal Lymphangiectasia Manifested as Unusual Edemas and Effusions: A Case Report.

Science.gov (United States)

Wang, Xuefeng; Jin, Hong; Wu, Weilu

2016-03-01

Primary intestinal lymphangiectasia (PIL) is a rare disorder of unknown etiology characterized by diffuse or localized dilation and eventual rupture of the enteric lymphatic vessels in mucosa, submucosa, and/or subserosa. Lymph, rich in all kinds of proteins and lymphocytes, leaks into the gastrointestinal tract via the affected lymphatic vessels causing hypoproteinemia and lymphopenia. The main symptom is variable degrees of pitting edemas of bilateral lower limbs. But edemas of any other parts of body, and mild serous effusions may also occur sometimes. PIL occurs in conjunction with a right hemifacial edema, a right upper limb lymphedema, asymmetric bilateral calves edemas, and a unilateral massive pleural effusion seems never to be reported before. In addition, increased enteric protein loss that may cause severe hypoproteinemia usually get overlooked, and the lymphatic system disorders always put the diagnoses in a dilemma.We described a case of a 17-year-old Chinese girl with a history of gradually progressive swellings of right-sided face, right upper limb, and bilateral calves since 3 to 4 months of age. A right-sided massive pleural effusion, a moderate pericardial effusion, and a mild ascites have been proved unchanged by a series of computerized tomography (CT) scans since 5 years ago. The diagnosis of PIL was finally confirmed by severe hypoproteinemia, endoscopic changes, and histology of jejunum biopsy. Further lymphoscintigraphy and lymphangiography also identified lymph leakage in her bowel and several abnormal lymphatic vessels. A high-protein, low-fat diet supplemented with medium-chain triglycerides (MCT) showed some benefit.This case suggested that PIL was a rare but important etiology of hypoproteinemia, effusions, and edemas. PIL, effusions, and lymphedema can be the features of multisegmental generalized lymphatic dysplasia. In addition, both lymphoscintigraphy and intranodal lymphangiography could be considered when lymphatic system

Vasoactive intestinal polypeptide (VIP) innervation of the human eyelid glands.

Seifert, P; Spitznas, M

1999-06-01

This study was conducted to obtain morphological proof of innervating nerve fibres in the glands of the human eyelid (accessory lacrimal glands of Wolfring, meibomian glands, goblet cells, glands of Zeis, glands of Moll, sweat glands, glands of lanugo hair follicles) and identification of the secretomotorically active neuropeptide vasoactive intestinal polypeptide (VIP) as a common transmitter. Epoxy-embedded ultrathin sections of tissue samples from human eyelids were studied using electron microscopy. Paraffin sections fixed in Bouin-Hollande solution were immunostained with rabbit antiserum against VIP. With the electron microscope we were able to identify nerves in the glandular stroma of all the glands examined with the exception of goblet cells. Intraepithelial single axons were only seen in the parenchyma of Wolfring glands. The morphological findings corresponded with the immunological finding of VIP-positive, nerve-like structures in the same locations, with the exception of lanugo hair follicle glands, and goblet cells. Our findings indicate that the glands of the eyelids and main lacrimal gland represent a functional unit with VIP as a possible common stimulating factor. Copyright 1999 Academic Press.

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

Expression of Anti-apoptotic Protein BAG3 in Human Sebaceous Gland Carcinoma of the Eyelid.

Science.gov (United States)

Yunoki, Tatsuya; Tabuchi, Yoshiaki; Hayashi, Atsushi

2017-04-01

Bcl-2-associated athanogene 3 (BAG3), a co-chaperone of heat shock protein 70 (HSP70), has been shown to play a role in anti-apoptosis of various malignant tumors. In this study, the expression of BAG3 was examined in human sebaceous gland carcinoma of the eyelid. The expression of BAG3 was evaluated by immunohistochemistry of surgical samples from 5 patients with sebaceous gland carcinoma in the eyelid. BAG3 was positive diffusely in the cytoplasm in all patients. The average positive rate of BAG3 was 73.0±26.0% in tumor cells of all patients. BAG3 was highly expressed in sebaceous gland carcinoma of the eyelid. BAG3 may play an important role in the pathogenesis and progression of sebaceous gland carcinoma of the eyelid.

Somogyi, Marie; Lyons, Lance J; Durairaj, Vikram

A healthy 31-year-old female presented with an elevated vascular lesion on the right lower eyelid margin. Histology results from excisional biopsy demonstrated a range of intradermally nested atypical melanocytes with negative staining for BRCA1-associated protein 1, confirming the diagnosis of Wiesner nevus. Wiesner nevi may be a cutaneous hallmark of the BRCA1-associated protein 1-associated cancer susceptibility syndrome, and to our knowledge, this is the first report of such a lesion presenting anywhere on the ocular adnexa.

This represents just the sixth case of gouty tophus of the eyelid reported in the literature.

Preliminary evidence that light through the eyelids can suppress melatonin and phase shift dim light melatonin onset.

Science.gov (United States)

Figueiro, Mariana G; Rea, Mark S

2012-05-07

A previous study reported a method for measuring the spectral transmittance of individual human eyelids. A prototype light mask using narrow-band "green" light (λmax = 527 nm) was used to deliver light through closed eyelids in two within-subjects studies. The first study investigated whether an individual-specific light dose could suppress melatonin by 40% through the closed eyelid without disrupting sleep. The light doses were delivered at three times during the night: 1) beginning (while subjects were awake), 2) middle (during rapid eye movement (REM) sleep), and 3) end (during non-REM sleep). The second study investigated whether two individual-specific light doses expected to suppress melatonin by 30% and 60% and delivered through subjects' closed eyelids before the time of their predicted minimum core body temperature would phase delay the timing of their dim light melatonin onset (DLMO). Compared to a dark control night, light delivered through eyelids suppressed melatonin by 36% (p = 0.01) after 60-minute light exposure at the beginning, 45% (p = 0.01) at the middle, and 56% (p light levels 1 and 2, respectively. These studies demonstrate that individual-specific doses of light delivered through closed eyelids can suppress melatonin and phase shift DLMO and may be used to treat circadian sleep disorders.

2007-01-01

The Purpose of this study was to evaluate retrospectively the management and prognosis of Merkel cell carcinoma of the eyelid in Japanese patients. Cases diagnosed as Merkel cell carcinoma of the eyelid from January 1993 to February 2005 in 111 institutions in Japan were included in this retrospective study. Management and prognosis were evaluated. The total number of cases enrolled was 21 (5 male and 16 female patients). Excision of the tumor was carried out in 18 cases. Two cases were treated with either irradiation or local injection of interferon after biopsy of the tumor. After initial treatment, there were recurrences in 3 cases; local recurrence in one case and nodal metastasis in two cases. No patient died because of Merkel cell carcinoma of the eyelid. Excision with wide surgical margins with irradiation is recommended as the first choice of treatment for Merkel cell carcinoma of the eyelid. Because the number of patients was only 21 and the duration of observation was short, further investigation is necessary to determine the optimal management and more accurate prognosis for Merkel cell carcinoma.

Acute hemorrhagic edema of infancy (AHEI) is an unusual form of leukocytoclastic vasculitis with dramatic distinguishing skin lesions that occurs in infants ages 4 to 24 months old. The disease presents with skin eruptions that usually start with large (1-5 cm), symmetrically distributed, hemorrhagic lesions in a characteristic cockade pattern. The lesions are typically located on the lower extremities, face (in particular the ears, cheeks, and eyelids), and gluteal area. Fever may accompany skin eruptions. Clinical presentation at onset requires clinical and laboratory examination to distinguish it from more serious diseases and other vasculitis. The main differential diagnosis of AHEI is Henoch-Schönlein purpura. AHEI is generally a self-limiting disease, so a conservative approach should be considered. Topical or systemic corticosteroid therapy has been reported to be beneficial, as well as antihistamines and dapsone, although AHEI usually resolves completely with or without treatment. We report two cases of AHEI and an update of the literature. © 2012 Wiley Periodicals, Inc.

En resumen se trata de una modificación quirúrgica que facilita la técnica, disminuye las complicaciones postoperatorias, mejora la recuperación y evita la sensación de cuerpo extraño intraocular de una resección conjuntivalBlepharoptosis is the abnormally low of the top eyelid during the direct look. Best results are obtained by resection or advance of the elevator muscle or aponeurosis, whenever the elevator has a suitable function. We present a modification to the Blaskovics´s technique for correction of moderate blepharoptosis, with good function of the elevator muscle. We present a serie of 10 cases where we used a variant of Blaskovics’s technique of resection of the elevator for surgical correction of ptosis. Seven were bilateral cases and 3 unilateral ones. In all the cases the elevator function was between 4 and 8 mm and ptosis was major than 4mm with visual field decrease in the direct look. Surgical technique included a cutaneous horizontal incision of Blepharoplasty, wide exhibition of elevator muscle and aponeurosis, respecting orbicular fatty bags and separating it from the palpebral conjunctive. In all the cases correction of the ptosis were obtained. The grade of asymmetry was lower than 0,3 cm. One case presented in the inmediate postoperatory opening of the suture in his medial side and had to be re-taken after 10 days. The palpebral postoperative edema was solved between 2 – 8th day allowing evaluation in that moment. Patient’s satisfaction was good or very good and the visual field was complete in all patients Classic surgical techniques and its modifications for correction of ptosis keep on being valid. With this modification that respects conjuctive we avoid to add morbidity to the surgical process. We think that

It is well known that blood perfusion is important for the survival of skin flaps. As no study has been conducted to investigate how the blood perfusion in human eyelid skin flaps is affected by the flap length and diathermy, the present study was carried out to investigate these in patients. Fifteen upper eyelids were dissected as part of a blepharoplastic procedure, releasing a 30-mm long piece of skin, while allowing the 5 mm wide distal part of the skin to remain attached, to mimic a skin flap (hereafter called a "skin flap"). Blood perfusion was measured before and after repeated diathermy, using laser speckle contrast imaging. Blood perfusion decreased from the base to the tip of the flap: 5 mm from the base, the perfusion was 69%, at 10 mm it was 40%, at 15 mm it was 20%, and at 20 mm it was only 13% of baseline values. Diathermy further decreased blood perfusion (measured 15 mm from the base) to 13% after applying diathermy for the first time, to 6% after the second and to 4% after the third applications of diathermy. Blood perfusion falls rapidly with distance from the base of skin flaps on the human eyelid, and diathermy reduces blood perfusion even further. Clinically, it may be advised that flaps with a width of 5 mm be no longer than 15 mm (i.e., a width:length ratio of 1:3), and that the use of diathermy should be carefully considered.

We report a case of upper airway obstruction after extubation in a 69-year-old female patient who underwent transurethral ureterolithotripsy (TUL). She had underwent bilateral modified radical neck dissection 7 years previously. TUL went smoothly in Trenderenburg position, and the extubation was performed after antagonism of neuromuscular block. The patient was closely observed in the operating theater, but about 10 minutes after extubation, she was noted to have dyspnea and tracheal tug. Dexamathasone 2 mg IV was given but was unsuccessful. Although we could support the airway with bag-mask ventilation, continuous stridor required re-intubation. Direct laryngoscopy revealed severe obstruction caused by laryngeal edema. An otolaryngologist was consulted and he performed tracheostomy. We transferred the patient to the intensive care unit for observation. Flexible fiberoptic scope examination performed on postoperative day (POD) 1 showed the decrease of the laryngeal edema. Tacheal tube was removed on POD 7 and she was discharged from the hospital POD 10 without further complications. Patients after a neck dissection may be at elevated risk for postoperative laryngeal edema caused by lymphatic destruction or venous congestion of the neck.

Background Edema associated with quetiapine has been described in only one case report to date and represents a potentially serious adverse reaction. Methods We present a case series of three patients who developed bilateral leg edema following initiation of quetiapine. Results One of these patients had a recurrence of edema with subsequent rechallenge. Another patient developed quetiapine-induced edema following a prior episode of olanzapine-induced edema. All the cases present a compelling temporal relationship between the drug challenge and the adverse event. Conclusions Prompt recognition and intervention with discontinuation of the offending agent is important for this potentially serious, seemingly idiosyncratic, vascular complication. PMID:19439156

2007-01-01

The purpose of this study was to report the effect of botulinum toxin for eyelid retraction in dysthyroid ophthalmopathy with or without hypertrophy of intraorbital muscles. We reviewed 28 eyes of 23 cases who received injection of botulinum toxin for eyelid retraction. Eyelid retraction improved in 23 eyes (82%). The height of palpebral fissure ranged from 8 to 12 mm, average 10.8 mm, before treatment. It ranged from 5 to 12 mm, average 9.4 mm, 2 weeks after treatment. The difference was significant. By magnetic resonance imaging (MRI), hypertrophy of levator and/or superior rectus muscle was present in 19 eyes and absent in 9 eyes. Eyelid retraction improved in 2 eyes (11%) in the former group and in one eye (11%) in the latter. Dalrymple sign was present in 28 eyes before and disappeared in 14 eyes after treatment. Graefe sign was present in 28 eyes before and disappeared in one eye after treatment. Botulinum toxin is effective for eyelid retraction and not for Graefe sign in dysthyroid ophthalmopathy.

Full Text Available Currently, ultrasound biomicroscopy (UBM is the only diagnostic method that uses a 50‑100 MHz transducer with a depth of penetration of 4 mm. This provides greater sensitivity and resolution.Aim. To visualize meibomian glands and to evaluate their morphological and functional status using UBM.Methods. UBM was performed in 14 patients aged 29‑81 with obvious meibomian gland dysfunction (MGD and healthy meibomian glands. 6 patients had no biomicroscopic signs of blepharitis while 8 patients had biomicroscopic signs of blepharitis, blepharoconjunctivitis, and MGD.Results. UBM provides detailed information on meibomian glands and eyelid margins and their pathological conditions, i.e., eyelid margin thickening due to inflammation, meibomian gland orifice obstruction, increase in distance between meibomian glands due to their atrophy, and cartilaginous tissue destruction. UBM findings may depend on patient age as well as on disease stage and severity. When re-positioning UBM transducer, bullous conjunctiva and subconjunctival cysts can be visualized. This provides differential diagnosis between opaque cysts and tumors.Conclusion. UBM combined with standard exams increases information value, reliability, and accuracy of the diagnostics of anterior segment disorders and facilitates the development of targeted therapeutic approaches. Further studies on diagnostic value of conjunctiva and eyelids UBM are required.

One of the most common complications of double eyelid operations is asymmetry. To reduce asymmetry, we fixed the dermis to the tarsal plate at the same level as the skin incision, and objectively evaluated the symmetry of the height using photogrammetry.Of 30 patients who had double eyelid operations by the intratarsal fixation technique, 15 patients completed a minimum follow-up of 6 months. After the skin incision and removal of the orbicularis oculi muscle and the orbital fat, the pretarsal fat pad was excised to expose the superior portion of the tarsal plate. The 3 fixation points were marked on the tarsal plate at the same level with the skin incision using a spreading caliper. The dermis was fixed to the marked points of the tarsal plate and the skin was closed.The height of the double eyelid was measured by clinical photography at 4 points when the eyes were opened and at 3 points when the eyes were closed. The height proportional index at each point was obtained by dividing the height of the left double eyelid by that of the right double eyelid. We compared each height proportional index with "1" to evaluate the symmetry of both double eyelids using a paired t test.The follow-up period was an average of 9.0 months. The mean height proportional indices were 0.97 (a), 0.96 (b), 0.98 (c), 1.08 (d), 0.97 (e), 1.02 (f), and 1.13 (g). According to a paired t test, the height of the left double eyelid was not different from that of the right double eyelid.Intratarsal fixation, along with other previously known methods, decreases asymmetric double eyelids.

Analysis of peritumoral edema

International Nuclear Information System (INIS)

Ikeda, Yukio; Nakazawa, Shozo

1984-01-01

In this study, seventy patients with brain tumors (34 glioblastomas, 21 meningiomas and 15 metastatic tumors) were examined by CT scan with and without contrast medium infusion and by postoperative histologic verification in all cases. Peritumoral hypodensity areas on CT scan have generally been interpreted as cerebral edema. Peritumoral edema as seen in CT scan was classified into four grades according to the ratio of the largest diameter of tumor and the size of the zone of edema. The grade of peritumoral edema was closely related to the degree of malignancy of the brain tumors. 8 out of 9 glioblastomas which demonstrated slight peritumorol edema, Grade I, had large cystic formations which seemed to serve as buffer action to compression mechanism by brain tumors. The grade of peritumoral edema was also related to the location of the tumor and venous involvement. Infusion of mannitol into the internal carotid artery is said to disrupt the blood-brain barrier. Intracarotid mannitol infusions in one glioblastoma produced the definite increase of contrast enhancement. Whether this phenomenon suggests an extravasation of contrast medium or the invasion of the tumor is not clear. The regional circulation and the extent of peritumoral edema was evaluated by means of dynamic CT scan. The CT number-time curve gave a few parameters. The peak value was considered to be related to the blood volume of the region of interest. It was a common finding that the peak value in the region of peritumoral edema was decreased, compared to the region of tumor and normal brain. Clinical application of dynamic CT scan may be useful to evaluate the regional circulation and the extent of peritumoral edema. (J.P.N.)

Eyelid contracture may indicate recurrent basal cell carcinoma, even after Mohs' micrographic surgery.

Mohs' micrographic surgery (MMS) is an effective means of margin control in the management of periocular basal cell carcinomas (BCC). We describe three cases of recurrent BCC that presented with progressive eyelid contracture after MMS. They illustrate high-risk factors for recurrence, namely large tumor size, medial canthal location, previous treatment, and aggressive histological features. Careful long-term surveillance with serial photography may identify early eyelid contracture and thus assist in the detection of recurrent BCC after MMS and improve patient outcome.

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 Edema is defined as a palpable swelling caused by an increase in interstitial fluid volume. Leg edema is a common problem with a wide range of possible causes and is the result of an imbalance in the filtration system between the capillary and interstitial spaces. Major causes of edema include venous obstruction, increased capillary permeability and increased plasma volume secondary to sodium and water retention. In both hospital and general practice, the patient with a swollen leg presents a common dilemma in diagnosis and treatment. The cause may be trivial or life-threatening and it is often difficult to determine the clinical pathway. The diagnosis can be narrowed by categorizing the edema according to its duration, distribution (unilateral or bilateral and accompanying symptoms. This work provides clinically oriented recommendations for the management of leg edema in adults.

The fractionated stereotactic radiotherapy by Cyberknife is an option in the treatment of eyes tumors. The advantages of the Cyberknife in the choroid melanomas are in its infra-millimetric precision, to the automated repositioning on the skull bones and to the conformity brought by the stereotaxy. The objective of this study was to validate the quality of repositioning and the immobility of the eyes with closed eyelids. Conclusion: the reproducibility of the eye positioning with closed eyelids seems enough to consider the conservative treatment of choroid melanomas by fractionated stereotactic radiotherapy by Cyberknife without implementation of fiducials nor retrobulbar anaesthesia.

Full Text Available When acute inflammation in anterior eye segment of a forward piece of an eye was stopped, ophthalmologists face a problem of absence of acute inflammation signs and at the same time complaints to the remain discomfort feelings. It causes dissatisfaction from the treatment. The complaints are typically caused by disturbance of tears productions. No accidental that the new group of diseases was allocated — the diseases of the ocular surface. Ocular surface is a difficult biologic system, including epithelium of the conjunctiva, cornea and limb, as well as the area costal margin eyelid and meibomian gland ducts. Pathological processes in conjunctiva, cornea and eyelids are linked with tears production. Ophthalmologists prescribes tears substitutions, providing short-term relief to patients. However, in respect that the lipid component of the tear film plays the key role in the preservation of its stability, eyelids hygiene is the basis for the treatment of dry eye associated with ocular surface diseases. Eyelids hygiene provides normal functioning of glands, restores the metabolic processes in skin and ensures the formation of a complete tear film. Protection of eyelids, especially the marginal edge from aggressive environmental agents, infections and parasites and is the basis for the prevention and treatment of blepharitis and dry eye syndrome. The most common clinical situations and algorithms of their treatment and prevention of dysfunction of the meibomian glands; demodectic blepharitis; seborrheic blepharitis; staphylococcal blepharitis; allergic blepharitis; barley and chalazion are discussed in the article. The prevention keratoconjunctival xerosis (before and postoperative period, caused by contact lenses, computer vision syndrome, remission after acute conjunctiva and cornea inflammation is also presented.

It has been difficulty to visualize lymphatics in living patients. Conventional or direct lymphography has been the gold standard for delineation of the lymphatic system, but this procedure is invasive, difficulty to perform, and harmful to the lymphatic vascular endothelium. The aim of our study was to determine its severity, and to understand the drainage patterns on patients with peripheral edema by functional lymphatic studies. Tc-99m antimony sulfide colloid 25 MBq with 0.4 ml volume was injected intradermally in the first, second and third web space of the foot or hand in 40 patients with peripheral edema (5 in upper extremity and 35 in lower extremity). Initial flow after injection and whole body images at approximately 30 minutes. 1-4 hours were obtained. In 9/40 cases with peripheral edema normal lymphoscintigram were revealed, primary lymphedema was observed in 5/31 cases. The imaging patterns in primary lymphedema were absent (3 cases) or delayed (2 cases) transport, lymphatic duct dilatation (1), cutoff (1), decrease in size and number of lymph nodes (2). The Common caused of edema in secondry lymphedema (26/31) were carcinoma (13), inflammation (5), post-operation (5), and unknown origin (3). The common imaging findings in carcinoma showed non-visualization of lymph nodes (13), dermal backflow (8), collateral circulation (5), and in inflammation lymphatic obstruction (2), increase in size and number of lymph nodes (2), delayed transport (1), and in post-operation dermal backflow (3), delayed transport (2), decrease in number and size of lymph node (2) Clear images patterns were observed difference between primary lymphedema an secondary lymphedema. Radionuclide lymphoscintigraphy is essentially non-invasive, easy to perform repeatedly, and harmless to the lymphatic vascular endothelium for evaluation of a patient with lymphedema

Patients and methods. We observed 8 children aged 3,5‑8 years (sex ratio was 1:1. In all cases, examination, palpation, surgical excision of the tumor with histological examination were performed. Results. Trichilemmoma, or pilomatricoma, was suggested from clinical manifestations. Epithelioma Malherbe was diagnosed by histology only. Microscopically, the tumor is surrounded by a capsule which includes two cell types. Peripheral basophilic cells are small cells with poor cytoplasm, indistinct borders, and deeply basophilic nucleus. Central shadow cells have a distinct border and a central unstained area. Islands of small basaloid epithelial cells with squamous cell focuses and cornification are embedded in the stroma. Epithelial lesions are often necrotized. Epithelial mass is surrounded by granulations with giant cells. Osseous trabeculae are often adjacent to necrotic lesions. Further follow-up revealed no complications or recurrences. Conclusions. Our observations and literature data suggest that epithelioma Malherbe is occured in 1.3 % of benign eyelid tumors in childern. Tumor growth is slow and non-invasive.

Edema is an accumulation of fluid in the interstitial space that occurs as the capillary filtration exceeds the limits of lymphatic drainage, producing noticeable clinical signs and symptoms. The rapid development of generalized pitting edema associated with systemic disease requires timely diagnosis and management. The chronic accumulation of edema in one or both lower extremities often indicates venous insufficiency, especially in the presence of dependent edema and hemosiderin deposition. Skin care is crucial in preventing skin breakdown and venous ulcers. Eczematous (stasis) dermatitis can be managed with emollients and topical steroid creams. Patients who have had deep venous thrombosis should wear compression stockings to prevent postthrombotic syndrome. If clinical suspicion for deep venous thrombosis remains high after negative results are noted on duplex ultrasonography, further investigation may include magnetic resonance venography to rule out pelvic or thigh proximal venous thrombosis or compression. Obstructive sleep apnea may cause bilateral leg edema even in the absence of pulmonary hypertension. Brawny, nonpitting skin with edema characterizes lymphedema, which can present in one or both lower extremities. Possible secondary causes of lymphedema include tumor, trauma, previous pelvic surgery, inguinal lymphadenectomy, and previous radiation therapy. Use of pneumatic compression devices or compression stockings may be helpful in these cases.

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.

Bone marrow edema of the knee joint is a frequent clinical picture in MR diagnostics. It can be accompanied by symptoms and pain in the joint. Diseases that are associated with bone marrow edema can be classified into different groups. Group 1 includes vascular ischemic bone marrow edema with osteonecrosis (synonyms: SONK or Ahlbaeck's disease), osteochondrosis dissecans, and bone marrow edema syndrome. Group 2 comprises traumatic or mechanical bone marrow edema. Group 3 encompasses reactive bone marrow edemas such as those occurring in gonarthrosis, postoperative bone marrow edemas, and reactive edemas in tumors or tumorlike diseases. Evidence for bone marrow edema is effectively provided by MRI, but purely morphological MR information is often unspecific so that anamnestic and clinical details are necessary in most cases for definitive disease classification.

Eyelid conditioning, including delay eyelid conditioning and trace eyelid conditioning, has been used extensively to study neural structures and mechanisms of learning and memory as a form of associative learning. In the present study, microcurrent electrical stimulation was used to stimulate the medial prefrontal cortex (mPFC) to induce delay eyelid conditioning in guinea pigs. The acquisition rate and relative latency of the conditioned eyelid response (CR) and the startle eyelid response (SR) were analyzed. The mPFC sites in the guinea pigs were examined under a light microscope following Nissl staining. In addition, the expression of Fos protein in neurons was detected using immunohistochemistry and western blot analysis. The results indicated that the acquisition rates of CR and SR were increased significantly (Pmicrocurrent electrical stimulation of the mPFC in guinea pigs was triggered by the expression of Fos protein. The observations of the present study further expand the understanding of conditioned reflexes and may aid future investigations into the formation of eyelid conditioning and the mechanisms underlying the circuit in various conditions.

Spread of edema with brain tumors

Cerebral edema associated with brain tumors is visualized on CT as a hypodensity lesion involving mainly the white matter. The detailed features of its evolution were investigated in a review of CT examinations performed on 56 patients with brain tumors, with the following results. 1. The susceptibility to edema varied according to the types of fibers. Association fibers were more sensitive to edema than projection and commissural fibers. 2. The edema had a characteristic of spreading along not only the association fibers but also the projection and commissural fibers. 3. The spread of edema along the association fibers was interupted in sites of convergence of the fibers such as the external capsule and just beneath the central sulcus in the certrum semiovale. 4. In some cases with intra-axial tumors, the edema extended mainly in the projection and commissural fibers considered to be more resistant to it. For example, in cases with parietal and temporal intra-axial tumors, the posterior limb of the internal capsule was often more edematous than the external capsule. 5. The edema associated with meningioma had a characteristic of spreading mainly along the association fibers. When situated close to the corpus callosum, however, the commissural fibers were also involved. Edema extending mainly in the internal capsule, thus, was rarely observed in meningioma. 6. There was unique pattern of spread of edema in frontal tumors, which differentiated their CT pattern. Therefore, the location of the tumor could be correctly diagnosed by the pattern of the edema extension, even near the central sulcus or in the operculum region. (author)

Gerzanich, Volodymyr; Simard, J Marc

2015-01-01

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. PMID:26661240

Eyelid Localization for Iris Identification

Directory of Open Access Journals (Sweden)

T. Ea

2008-12-01

Full Text Available This article presents a new eyelid localization algorithm based on a parabolic curve fitting. To deal with eyelashes, low contrast or false detection due to iris texture, we propose a two steps algorithm. First, possible edge candidates are selected by applying edge detection on a restricted area inside the iris. Then, a gradient maximization is applied along every parabola, on a larger area, to refine parameters and select the best one. Experiments have been conducted on a database of 151 iris that have been manually segmented. The performance evaluation is carried out by comparing the segmented images obtained by the proposed method with the manual segmentation. The results are satisfactory in more than 90% of the cases.

Asahi, Minoru; Kikuchi, Haruhiko; Hirai, Osamu

1992-01-01

Brain edema associated with intracranial meningiomas was investigated on 80 patients, excluding recurrent cases. Statistically significant positive correlations with the degree of edema were found with large tumors, the convexity or parasagittal locations, the venous outflow disturbance, and the evidence of cortical disruption or peritumoral enhancement visualized on computed tomography or magnetic resonance imagings. Patients with a short clinical history and with angiographic evidence of hypervascularity tended to have edema, but there was no statistical significance. It is concluded that various factors are responsible for the edema associated with meningiomas and that it would be hard to determine the most important cause, since each factor plays a part edema production, spread, and resolution.

Patricia Mitiko Santello Akaishi

2011-08-01

Full Text Available PURPOSE: External dacryocystorhinostomy is routinely performed through a cutaneous vertical incision placed on the lateral aspect of the nose. The lower eyelid crease approach has been seldom reported. The purpose of this study is to report the cosmetic and functional results of the lid crease approach for external dacryocystorhinostomy in a series of patients. METHODS: Prospective, interventional case series. Twenty-five consecutive patients (17 women ranging in age from 3 to 85 years (mean ± SD= 44.84 ± 23.67 were included in the study. All patients but one underwent unilateral external dacryocystorhinostomy with a 10 to 15 mm horizontal incision placed on a subciliary relaxed eyelid tension line. The inner canthus was photographed with a Nikon D70S digital camera with a macrolens and resolution of 3008 x 2000 pixels at 1, 3 and 6 months after surgery. The resulting scar was judged from the photographs by 3 observers (ophthalmologist, plastic and head and neck surgeons according to a four level scale (1= unapparent, 2= minimally visible, 3= moderately visible, 4= very visible. RESULTS: The surgery was easily performed in all patients with a 90.48% success. Three of the elderly patients (ages 61, 79 and 85 yr developed mild lacrimal punctum ectropion, which resolved with conservative treatment. One patient had a hypometric blink which spontaneously recovered within one month. The mean score for scar visibility was 2.19 (1st mo, 1.65 (3th mo and 1.44 (6th mo. CONCLUSIONS: The eyelid crease approach is an excellent option for external dacryocystorhinostomy. It leaves an unapparent scar since the first month after surgery, even in younger patients. The functional results are excellent and comparable to other techniques. Care should be taken in elderly patients with lower eyelid laxity in order to prevent lacrimal punctum ectropion.

In this study, retrospective review of case series was performed.Participants: All patients who underwent ectropion or entropion surgery in a tertiary medical center between 2007 and 2014 were included. The etiology of eyelid malpositioning was involutional or cicatricial.Methods: The medical files of the study participants were reviewed for the presence and type of glaucoma, medical treatment, duration of treatment, and the amount of drops per day. These data were compared to a matched control group of 101 patients who underwent blepharoplasty for dermatochalasis in the same department during the same period.Main outcome measure: In this study, the prevalence of glaucoma in individuals with ectropion or entropion was the main outcome measure.Results: A total of 227 patients (57% men, mean age: 79.2 years who underwent ectropion or entropion surgery comprised the study group and 101 patients who underwent upper blepharoplasty for dermatochalasis comprised the control group. Compared to four patients in the control group (4%, P=0.01, 30 of the study patients (13.2% had coexisting glaucoma. Of 30 glaucomatous patients, 25 had primary open-angle glaucoma for a mean duration of 10.3 years. The glaucomatous patients were treated with an average of 2.7 antiglaucoma medications.Conclusion: An increased prevalence of known glaucoma in patients undergoing ectropion or entropion repair surgery was found. This observation may indicate that the chronic usage of topical anti-glaucoma eyedrops may lead to an increased risk of developing eyelid malpositions, especially in

The pronounced inspiratory efforts following UAO lead to excessive negative inspiratory pressure, which may cause acute pulmonary edema. Early recognition and prompt treatment of NPPE is necessary to prevent patient morbidity and mortality. In addition, the physician should carefully manage the patient who has risk factors of UAO to prevent this situation. We experienced a case of NPPE following laryngospasm after tracheal extubation in an obese patient who underwent open reduction of orbital wall and nasal bone surgery.

1992-01-01

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.

Bone marrow edema in sports: General concepts

Vanhoenacker, F.M.; Snoeckx, A.

2007-01-01

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

To study the epidemiologic, clinical and histological aspects of eyelid carcinomas in our context, and to evaluate our surgical management on an oncological, functional and aesthetic level. This work is a retrospective bicentric study extended over a 5-year period between January 2009 and December 2013, including 64 patients with eyelid carcinoma undergoing surgery in the Plastic and Reconstructive Surgery Department at the Avicenne University Hospital of Rabat and in the ENT/Head and Neck Surgery Department at the Hassan II University Hospital of Fez. The study included 25 men and 39 women with a mean age of 60.6 ± 15.33 years. Advanced age and chronic sun exposure were the most important risk factors. The most commonly involved site was the lower eyelid (53%). Histological examination emphasized the very high prevalence of basal cell carcinoma (90.62%). Surgical treatment was performed in all our patients followed by an extemporaneous and/or standard histological examination of the surgical specimen. Exenteration was performed in one patient with adjuvant radiation therapy. Reconstruction incorporated a variety of techniques, of which total skin graft and Mustardé flap were the most common in our series. Aside from a few complications, the postoperative results were satisfactory for the majority of our patients. Malignant tumors of the eyelids, of which basal cell carcinoma is the most common, pose a therapeutic problem where surgery remains the most utilized treatment option. The best treatment is prevention and diagnosis of early lesions to improve prognosis and to avoid worse outcomes. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

2011-01-01

Full Text Available Pulmonary edema has been reported in SCUBA divers, apnea divers, and long-distance swimmers however, no instances of pulmonary edema in triathletes exist in the scientific literature. Pulmonary edema may cause seizures and loss of consciousness which in a water environment may become life threatening. This paper describes pulmonary edema in three female triathletes. Signs and symptoms including cough, fatigue, dyspnea, haemoptysis, and rales may occur within minutes of immersion. Contributing factors include hemodynamic changes due to water immersion, cold exposure, and exertion which elevate cardiac output, causing pulmonary capillary stress failure, resulting in extravasation of fluid into the airspace of the lung. Previous history is a major risk factor. Treatment involves immediate removal from immersion and in more serious cases, hospitalization, and oxygen administration. Immersion pulmonary edema is a critical environmental illness of which triathletes, race organizers, and medical staff, should be made aware.

Jéssica Carolinne Damasceno

Full Text Available ABSTRACT Purpose: Malignant lesions of the eyelid are the most common eye cancers. Although rarely lethal, late diagnosis can lead to serious visual morbidity. Definitive diagnosis of neoplastic lesions is pathological. Indications and types of eyelid lesions in a single high-volume ophthalmic reference center in Sao Paulo, Brazil, were analyzed. Methods: The surgical pathological reports of patients who underwent eye removal procedures between January 2000 and December 2012 were retrieved from the electronic database of the Ophthalmology Department and retrospectively reviewed. Data regarding the final anatomopathological diagnosis, sex, and age were analyzed via the χ2 test with Yates' correction. Results: Of the 1,113 eyelid tumors resected over the 13-year study period, 324 (29% lesions were malignant. The most prevalent lesions were basal cell, squamous cell, and sebaceous gland carcinomas. The median ages of patients (females, n=165, 51%; males, n=159, 49% with a diagnosis of basal cell, squamous cell, and sebaceous gland carcinomas were 65, 75, and 70 years, respectively. Conclusion: This is the largest retrospective cohort analysis of eyelid tumors in a Latin American population. These findings are in agreement with those from large centers in other countries and regions.

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.)

AJCC utilizes a primary tumor, lymph node, metastasis (pTNM cancer staging approach.Objective: We wanted to determine if the AJCC pTNM carcinoma staging system identified patients with highly aggressive carcinoma of the eyelid. We also wanted to determine if there were any unexpected issues in its practical application. Design: We conducted a 15-year, consecutive, retrospective review of all cases of excisional biopsy for carcinoma of the eyelid. We reviewed the original histopathology slides and complete pathology records for each case.Results: Over a 15-year review period, 52 cases of excisional biopsy for carcinoma of the eyelid were identified. The average age of the study population was 72 years. Nodular well-differentiated basal cell carcinoma (BCC was the predominant histology for 85% of cases. Morpheaform/metatypical BCC was the next dominant at 9%. Squamous cell carcinoma and sebaceous carcinoma followed at 4% and 2%, respectively. We were able to assign clear staging to 50 of the 52 cases with the available pathology data. The stage results were as follows: stage 1A 72%, stage 1B 22%, stage II 4%, stage III 2%, with no cases of stage IV metastatic disease.Conclusions: The 7th edition AJCC Carcinoma of the Eyelid chapter proved to be a practical tool for carcinoma staging of the eyelid. The largest tumor dimension remains an effective predictive factor. High-grade pathologic prognostic factors such as tumor necrosis or perineural spread had a 100% association with a final stage of II or greater.

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 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

The water in normal and edematous brain tissues of rats was studied by the pulse nuclear magnetic resonance (NMR) technique, measuring the longitudinal relaxation time (T1) and the transverse relaxation time (T2). In the normal brain, T1 and T2 were single components, both shorter than in pure water. Prolongation and separation of T2 into two components, one fast and one slow, were the characteristic findings in brain edema induced by both cold injury and triethyl tin (TET), although some differences between the two types of edema existed in the content of the lesion and in the degree of changes in T1 and T2 values. Quantitative analysis of T1 and T2 values in their time course relating to water content demonstrated that prolongation of T1 referred to the volume of increased water in tissues examined, and that two phases of T2 reflected the distribution and the content of the edema fluid. From the analysis of the slow component of T2 versus water content during edema formation, it was demonstrated that the increase in edema fluid was steady, and its content was constant during formation of TET-induced edema. On the contrary, during the formation of cold-injury edema, water-rich edema fluid increased during the initial few hours, and protein-rich edema fluid increased thereafter. It was concluded that proton NMR relaxation time measurements may provide new understanding in the field of brain edema research

Full Text Available PURPOSE: To review the role of Mustarde’s flap for post basal cell carcinoma excision lower eyelid reconstruction , its clinical outcomes and complications. METHODS: The Mustarde’s rotational cheek flap has been used to reconstruct the lower eyelids of 16 patients from 2008 to 2015 in proven cases of bcc. RESULT S: Mustarde’s flaps have very high functionally as well as cosmetic acceptability with minimum patient morbidity. The most frequent complications were downward contraction and sagging of the flap and ectropion of the lid margin. To prevent them, the zygomatico - cheek flap must be carefully designed, rotated, and sutured as high as possible so that immediately postoperatively, t he palpebral fissure is only a narrow slit.

Full Text Available Congenital ptosis (CP represents a significant reconstructive problem Numerous studies have not yet provided full and satisfactory results. In this study, we have presented our experience in the surgical treatment of 108 patients by the use of Son Ye Guang's modified method - frontal muscle transposition. A total of 108 patients with CP were surgically treated at the Clinic for Plastic Surgery and Burns of the Military Medical Academy in the period 1991-2000. Unilateral ptosis was operated in 85 patients, and bilateral in 23 patients. CP was more frequently found in males (58.34% than in females (41.66%. The youngest patient was only 5.5 years old, and the oldest was 42, the average age was 21.3 years. All patients were operated on by the same surgeon, and were monitored monthly during the first six months and then twice a year for the next 3 years. Postoperative results were evaluated after 6 months: the action of raising the eyelids was compared to the full amplitude of movement of the eye on the healthy side. The closure of the eyelids and the symmetry of the palpebral fissure in a steady horizontal view was also assessed. The action of the opening as well as closure of the eyelids in full amplitude was obtained in all operated patients. Asymmetry of the palpebral fissure in a steady horizontal view up to 1 mm did not require additional correction. In 9 cases, asymmetry of the palpebral fissure greater than 1 mm was subsequently corrected. The advantages of this surgical method compared to the other, previously described techniques, were emphasized in the conclusion. The main advantage was the elimination of postoperative lagophthalmos, which represented the problem in all previously used methods.

Purpose: To analyze the results of radical radiotherapy by electron beams for squamous cell carcinoma (SCC) of the eyelid and to find the possible prognostic factors. Materials and Methods: Records of 38 patients with histologically confirmed SCC of the eyelid who underwent electron beam radiation therapy between 1964 and 2010 in our institution were retrospectively reviewed. Median tumor size was 15 mm (range, 3–40 mm). T stage was T1 in three, T2a in six, T2b in 14, and T3a in 15 patients. Four patients had nodal metastasis. Of the 38 patients, 14 had relapsed disease after prior treatment. Median radiation dose was 60.0 Gy (range, 45.0–70.4 Gy). Median follow-up was 72.5 months (range, 2.0–369 months). Results: 5-year local relapse-free, nodal relapse-free, distant metastasis-free and relapse-free rates for all patients were 71.8%, 77.5%, 90.6% and 58.0%, respectively. In seven patients, lymph node metastases occurred in 11 faciocervical regions. The 5-year overall survival was 79.5%. T stage and radiation dose expressed in EQD 2 Gy tended to have impacts on local control. Relapsed patients showed unfavorable local relapse-free rate, however this was without statistical significance. Of the 14 patients who died, 12 succumbed to concurrent diseases. Grade 3 or greater severe late morbidities (CTCAE ver4.0) were observed in nine patients. Due to the morbidities, two patients lost their vision. Conclusion: Radical radiotherapy for SCC of the eyelid yielded good results and could be a treatment option. Whether radiation-dose escalation could improve local control in advanced T stages and relapsed patients needs further study

Additionally, 36‑item Medical Outcomes Study-Short Form (MOS-SF-36 and benefit evaluation method were developed. Methods. Information analysis and mathematical methods and public health technology evaluation methods (i.e., modelling, analysis of disease burden, and budget impact analysis were applied to economic aspect study. Decision tree model based on these finding was developed and applied to cost estimating of blepharoconjunctival and exogenous dry eye treatment in computer vision syndrome. Two scenarios of patient management were considered, i.e., typical management and management using therapeutic eyelid hygiene. Similar model was developed for early postoperative period after LASIK. Short-run analysis (1 year was performed, direct medical costs were considered. This analysis implies the calculation of overall cost (economic burden of the disease. Official data on adult population size in 2014 and the occurrence of the disease were used to assess prevalence. Budget impact analysis evaluates the difference in total economic effects due to comparison technology use in money terms. Sensitivity analysis assesses the stability of simulation results. Medical treatment cost was considered the most valuable parameter. Results and conclusions. Direct medical costs of typical management and management using therapeutic eyelid hygiene in demodicosis, computer vision syndrome, and after LASIK were 14,623 RUB and 9,200 RUB (savings of 37 %, 17,630 RUB and 9,200 RUB (savings of 47 %, 4,425.5 RUB and 3,004 RUB (savings of 32 %, respectively. Analysis of economic burden with respect to disease occurrence and typical management costs demonstrated that in 2015 this parameter was estimated as 576,198,416,556 RUB. In terms of direct medical costs, therapeutic eyelid hygiene saves 44

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.

Regional pulmonary edema caused by acute mitral insufficiency after rupture of chordae tendinae with prolaps of the posterior mitral valve

An unilateral or predominantly lobar pulmonary edema is an unusual clinical or radiological finding, often misdiagnosed as one of the more common causes of focal lung disease. We report 2 cases of a regional pulmonary edema caused by the acute onset of a severe mitral insufficiency after the rupture of chordae tendinae resulting in a prolaps of the posterior mitral leaflet. In both cases the regional pulmonary edema was initially misdiagnosed as a pneumonic infiltration, which delayed the cardiological diagnostical procedures and the surgical intervention. The mechanism of the regional edema is an excentric regurgitation jet into the left atrium, which is usually directed to the orifice of the right upper lobe pulmonary vein which increases the hydrostatic vascular pressure in the corresponding lung segment. For the confirmation of the diagnosis, transesophageal echogradiographye is helpful in documenting the direction of the regurgitant flow and detecting differential gradients between the right and left pulmonary venous systems. The pulmonary infiltrations, which persisted for several weeks, dissappeared within a few days after surgical mitral-valve-reconstruction in both cases. (orig.) [de

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.

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.

Full Text Available Neurogenic pulmonary edema is a life threatening complication of severe central nervous system injury. The most common cause of neurogenic pulmonary edema is subarachnoid hemorrhage followed by head trauma and epilepsy. The rare causes are cervical spine trauma, multiplesclerosis, cerebellar hemorrhage and intracranial tumors. Neurogenic pulmonary edema is characterized by an increase in extravascular lung water in patients who have sustained a sudden change in neurologic condition. The exact pathophysiology is unclear but it probably involves an adrenergic response to the central nervous system injury which leads to increased catecholamine, pulmonary hydrostatic pressure and increased lung capillary permeability. The presenting symptoms are nonspecific and often include dyspnea, tachypnea, tachycardia, hypoxemia, pinkfroty secretion, bilateral pulmonary infiltrates and crackles. These symptoms start within minutes or hours and resolves 48-72 hours that typically for neurogenic pulmonary edema. Basic principles of treatment, surgical decompression, reduce intracranial pressure, controlled ventilation with suplemental oxygen, positive end expiratory pressure and diuresis. We report a case with neurogenic pulmonary edema that occured after head trauma. (Journal of the Turkish Society Intensive Care 2012; 10: 59-62

1984-08-01

Retinal hemorrhages can be associated with typical cystoid macular edema. We examined the fundus photographs and fluorescein angiograms of 313 eyes of 264 patients with documented cystoid macular edema to establish the incidence and characteristics of associated intraretinal hemorrhages. As we wanted to study only those hemorrhages unique to cystoid macular edema, we excluded 86 eyes because the patients had diseases known to be associated with retinal hemorrhages. These diseases included diabetes mellitus, branch retinal vein occlusion, hypertensive retinopathy, venous stasis retinopathy, and perifoveal telangiectasia. Of the remaining 227 eyes with cystoid macular edema, 56 (24.7%) were identified with retinal hemorrhages not associated with systemic disease. The hemorrhages were characteristically oval, round, or linear and frequently filled or partially filled the intraretinal cystoid space. In many patients, a blood-fluid level was observed.

Osmotherapy in brain edema

2012-01-01

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.

[Acute neurogenic pulmonary edema].

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.

Normal structure of the accessory organs of the eye is essential for normal eye physiology. Among the most important accessory organs of the eye are the eyelids, the conjunctiva-associated lymphoid tissue (CALT) and the lacrimal gland (LG). The aim of this study was to demonstrate the histological structure of the eyelids and LG by histochemical and ultrastructural analysis. The study was performed on 13 adult female Bilgorajska geese. Eyelid samples were stained with the Alcian blue (AB pH 2.5) and periodic acid-Schiff (PAS) methods. Staining methods used for LG were AB pH 2.5, aldehyde fuchsin (AF), PAS and Hale's dialysed iron (HDI). Within the connective tissue of the eyelids, well-developed, diffuse, CALT follicles were observed, mostly under the conjunctival epithelium. Numerous lymphocytes were present within loose connective tissue. Staining of the eyelids with the PAS method demonstrated the presence of goblet cells of a mucous nature, and AB pH 2.5 staining indicated the presence of sulfated acid mucopolysaccharides. PAS staining of LG revealed the presence of secretory cells containing weakly PAS-positive granules. All epithelial cells of the corpus glandulae and the duct systems reacted positively to AB pH 2.5. HDI staining detected the presence of carboxylated acid mucopolysaccharides. Transmission electron microscopy investigations revealed two types of secretory epithelial cells in LG. Both types of LG cells contained drop-like secretory vesicles of different sizes with low or high electron density in cytoplasm, as well as small and large lipid vacuoles, and numerous small primary lysosomes.

Reinke edema is one of the common cause of dysphonia middle-aged population, and severe thickening of vocal folds require surgical treatment. Smoking plays a major role on etiology. Vocal fold cysts are also benign lesions and vocal trauma blamed for acquired cysts. We would like to present 3 cases with vocal fold cyst related with Reinke edema. First case had a subepidermal epidermoid cyst with Reinke edema, which could be easily observed before surgery during laryngostroboscopy. Second case had a mucous retention cyst into the edematous Reinke tissue, which was detected during surgical intervention, and third case had a epidermoid cyst that occurred 2 months after before microlaryngeal operation regarding Reinke edema reduction. These 3 cases revealed that surgical management of Reinke edema needs a careful dissection and close follow-up after surgery for presence of vocal fold cysts.

Cerebral edema is one of the main acute complications arising after irradiation of brain tumors. Microbeam radiation therapy (MRT), an innovative experimental radiotherapy technique using spatially fractionated synchrotron x-rays, has been shown to spare radiosensitive tissues such as mammal brains. The aim of this study was to determine if cerebral edema occurs after MRT using diffusion-weighted MRI and microgravimetry. Prone Swiss nude mice's heads were positioned horizontally in the synchrotron x-ray beam and the upper part of the left hemisphere was irradiated in the antero-posterior direction by an array of 18 planar microbeams (25 mm wide, on-center spacing 211 mm, height 4 mm, entrance dose 312 Gy or 1000 Gy). An apparent diffusion coefficient (ADC) was measured at 7 T 1, 7, 14, 21 and 28 days after irradiation. Eventually, the cerebral water content (CWC) was determined by microgravimetry. The ADC and CWC in the irradiated (312 Gy or 1000 Gy) and in the contralateral non-irradiated hemispheres were not significantly different at all measurement times, with two exceptions: (1) a 9% ADC decrease (p < 0.05) was observed in the irradiated cortex 1 day after exposure to 312 Gy, (2) a 0.7% increase (p < 0.05) in the CWC was measured in the irradiated hemispheres 1 day after exposure to 1000 Gy. The results demonstrate the presence of a minor and transient cellular edema (ADC decrease) at 1 day after a 312 Gy exposure, without a significant CWC increase. One day after a 1000 Gy exposure, the CWC increased, while the ADC remained unchanged and may reflect the simultaneous presence of cellular and vasogenic edema. Both types of edema disappear within a week after microbeam exposure which may confirm the normal tissue sparing effect of MRT. For more information on this article, see medicalphysicsweb.org.

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 ( 0.05), 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

The purpose of our study is to describe shifting bone marrow edema in the knee as the MR imaging feature of intra-articular regional migratory osteoporosis of the knee. Five men, aged 45-73 years, were referred by orthopedic surgeons for MR imaging evaluation of knee pain, which had been present for 2 weeks to 6 months. One patient had a prior history of blunt trauma. None had risk factors for osteonecrosis. Four patients had two MR examinations and the patient with prior blunt trauma had four. Plain radiographs were obtained in all patients. In all cases, a large area of marrow edema initially involved a femoral condyle, with migration of the bone marrow edema to the other femoral condyle, tibia, and/or patella occurring over a 2- to 4-month period. Adjacent soft tissue edema was present in all five patients, while none had a joint effusion. Radiographs of two patients showed generalized osteopenia. In the absence of acute trauma or clinical suspicion of infection, a large area of bone marrow edema without a zone of demarcation may represent intra-articular regional migratory osteoporosis. Demonstration of shifting bone marrow edema on follow-up examinations suggests this diagnosis. (orig.)

Muscle hyperactivity of grimacing muscles, including the orbicularis oculi and corrugator supercilii muscles that cause crow's feet and a glabellar frown line with ageing, cannot be accurately evaluated by surface observation. In 71 subjects, this study investigated the extent to which grimacing muscles are innervated by the bilateral motor cortices, whether the corticofacial projection to the grimacing muscles affects the facially innervated stapedius muscle tone by measuring static compliance of the tympanic membrane, and whether unilateral tight eyelid closure with contraction of the grimacing muscles changes static compliance. Unilateral tight eyelid closure and its subsequent change in the contralateral vertical medial eyebrow position revealed that motor neurons of the orbicularis oculi and corrugator supercilii muscles were innervated by the bilateral motor cortices with weak-to-strong contralateral dominance. The orbicularis oculi, corrugator supercilii, and stapedius muscles innervated by the bilateral motor cortices had increased muscle hyperactivity, which lowered the vertical medial eyebrow position and decreased the static compliance of the tympanic membrane more than those innervated by the unilateral motor cortex. Unilateral enhanced tight eyelid closure with contraction of the grimacing muscles in certain subjects ipsilaterally decreased the static compliance with increased contraction of the stapedius muscle, which probably occurs to immobilise the tympanic membrane and protect the inner ear from loud sound. Evaluation of unilateral tight eyelid closure and the subsequent change in the contralateral vertical medial eyebrow position as well as a measurement of the static compliance for the stapedius muscle tone has revealed muscle hyperactivity of grimacing muscles.

To evaluate the incidence, quantity, and presentation of intra- and extraosseous edema accompanying benign and malignant primary bone lesions, the magnetic resonance (MR) studies of 63 consecutive patients with histologically proven primary bone tumors were reviewed. MR scans were assessed for the presence and quantity of marrow and soft tissue edema and correlated with preoperative findings, resected specimens and follow-up data. The signal intensity and enhancement of tumor and edema prior to and after intravenous administration (if any) of gadolinium-labled diethylene triamine pentaacetate (Gd-DTPA) was analyzed. Marrow edema was encountered adjacent to 8 of 39 maglinant tumors and 14 of 24 benign lesions. Soft tissue edema was found accompanying 28 of 39 malignancies and 10 of 24 benign disorders. On enhanced T1-weighted MR images tumor and edema were difficult to differentiate. Tumor inhomogeneity made this differentiation easier on T2-weighted sequences. In 36 patients the contrast medium Gd-DTPA was used. Edema was present in 27 of these patients and the respective enhancement of tumor and edema could be compared. Edema always enhanced homogeneously, and in most cases it enhanced to a similar degree as or more than tumor. Marrow and, more specifically, soft tissue edema is a frequent finding adjacent to primary bone tumors. The mere presence and quantity of marrow and soft tissue edema are unreliable indicators of the biologic potential of a lesion. Unenhanced MR scans cannot always differentiate between tumor and edema, but the administration of Gd-DTPA is of assistance in differentiating tumor from edema. Awareness of marrow and/or soft tissue edema adjacent to bone lesions is of importance because edema can be a pitfall in the diagnostic work-up and staging prior to biopsy or surgery. (orig.)

Full Text Available Chronic constipation is a common condition which may result in fecal impaction. A 13-year-old male with chronic constipation and encopresis presented with fecal impaction for three weeks. The impaction caused abdominal pain, distension, encopresis, and decreased oral intake. He was found in severe distress with non-pitting edema of his feet and ankles along with perineal edema. The pedal edema worsened after receiving a fluid bolus, so concern arose for venous compression or a thrombus. A Duplex Ultrasound demonstrated changes in the venous waveforms of the bilateral external iliac and common femoral veins without thrombosis. Manual disimpaction and polyethylene glycol 3350 with electrolytes resolved the pedal and perineal edema. Four months later, he had soft bowel movements without recurrence of the edema. A repeat Duplex Ultrasound was normal. We present a child in whom severe fecal impaction caused pelvic venous compression resulting in bilateral pedal and perineal edema.

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.

Grisolia, Ana Beatriz Diniz; Couso, Ricardo Christopher; Matayoshi, Suzana; Douglas, Raymond S; Briceño, César Augusto

2017-08-09

Thyroid eye disease (TED) is an autoimmune condition with an unpredictable course that may lead to permanent facial disfigurement. Eyelid retraction is one of the most common findings, and frequently demands attention due to ocular exposure and impaired cosmesis. Surgical treatment remains the most effective option, but there is a role for temporary corrections during the active phase of the disease, as well as in patients who are poor surgical candidates. The aim of this review is to describe the non-surgical modalities currently available for treatment of eyelid malposition in TED. The authors have focused on the use of hyaluronic acid, triamcinolone injections and botulinum toxin type A as non-surgical treatment alternatives, paying special attention to dosing, technique, efficacy and duration of effect. Non-surgical treatment modalities may represent viable in cases where surgical correction is not an option. Although temporary, these modalities appear to be beneficial for ocular exposure remediation, improving quality of life and broadening our therapeutic arsenal. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Eyelid cancer is a therapeutic challenge due to the cosmetic and functional implications of this anatomical region and the objectives of therapy are tumor control, functional and cosmetic outcome. The present study was performed to analyze local control, toxicity, functional and cosmetic results in patients with eyelid carcinoma treated by interstitial brachytherapy. In this study 60 patients with eyelid carcinoma were treated by interstitial brachytherapy using iridium ({sup 192}Ir) wires with a linear activity of 1.2-1.7 mCi/cm. The prescription dose was 51-70 Gy (mean 65 Gy, median 66 Gy). Of the 60 patients 51 (85.0 %) had received no prior treatment, 4 (6.7 %) had received previous surgery with positive or close margins and 5 (8.3 %) had suffered local recurrence after surgery. Of the tumors 52 (86.7 %) were basal cell carcinoma, 7 (11.7 %) squamous cell carcinoma and 1 (1.7 %) Merkel cell carcinoma. Clinical stage of the 51 previously untreated tumors was 38 T1N0, 12 T2N0 and 1 T3N0. Mean follow-up was 92 months (range 6-253 months). Local control was maintained in 96.7 % of patients. Late effects higher than grade 2 were observed in 3.0 % of cases. Functional and cosmetic outcomes were optimal in 68.4 % of patients. Interstitial brachytherapy for carcinoma of the eyelid can achieve local control, cosmetic and functional results comparable to those of surgery. (orig.)

Full Text Available Due to the importance of clinically significant macular edema in diabetic patients, this study is aimed to determine if laser photocoagulation is effective in the treatment of clinically significant diabetic macular edema. 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 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

A case was considered in detail of a patient with pulmonary edema of immunnocomplex nature in aerogenic intoxication by nickel tetracarbonyl. It was shown that acute aerogenic intoxication nickel carbonyl by led to unfolded toxic autoimmune syndrome. In this case autoimmune immunecomplex pulmonary lesion (AIPL) menifested by progressing pulmonary edema with expressed parenchymatous respiratory insufficiency played a leading role. Lesion of endothelium of pulmonary capillaries by immune complexes has the most significant in pathogenesis of pulmonary edema. The fact that edema appears due to AIPL, is confirmed by high efficiency of glucocorticoid therapy. Use of glucorticoids serves as a diagnostic test which provides an effective roentgenologic diagnosis of AIPL and differential diagnosis of any other pathological processes in the lungs

Full text: Currently, myocardial edema monitoring after acute myocardial infarction (AMI) is based on visualization of the region with increased signal-intensity on T2-weighted images. Native T1 and T2 mapping are promising novel MRI techniques to quantitatively assess myocardial edema. The purpose of the study was to quantitatively evaluate resorption of myocardial edema following AMI by native T1 and T2 -mapping cardiac magnetic resonance imaging (CMR). CMR (1.5 Tesla Philips Achieva) was performed in 30 patients four times after reperfused AMI at baseline (BL) at 9±6 days after infarction and at 7±1 weeks (follow-up 1, FU1), 3.6±0.5 months (FU2) and 6.5±0.7 months (FU3), respectively. Edema sensitive black-blood T2-weighted (T2w) STIR CMR was performed on end-diastolic LV short-axes. A free-breathing, navigatorgated multi-echo sequence was used for short-axis T2 mapping. T1 mapping was performed using the modified look-locker inversion recovery (MOLLI) sequence. T2 maps were calculated from nine and T1 maps from eight echoes using a dedicated plug-in written for OsiriX software. Two experienced observers independently evaluated T2w-CMR as well as T1 and T2 mapping using the HeAT-Software applying a threshold method. Size of edema and prolongation of the native T1- or T2-time was measured using a cutoff >2SD of remote normal myocardium. Edema size continuously decreased from BL with 32.8 %LV to 24.6 %LV at FU1, to 19.1 %LV at FU2 and to 16.4 %LV at FU3 using T2w-CMR. An almost identical decrease of edema size was observed using native T1 and T2 - mapping. T2 times only decreased between BL from 79±5 ms to 73±2 ms at FU1 (P<0.05), but no further change was observed at later time points with 70±5 ms at FU2 and 70±6 ms at FU3. At all time points the T2 times of remote normal myocardium were about 50±2 ms and significantly lower compared to the edema zone. Also native T1 time within the edema was with 1253 ±103 ms significantly increased compared to remote

2015-03-06

An eyelid or orbital lipogranuloma can occur following nasal packing with liquid paraffin, petroleum jelly or an antibiotic-based cream. It usually presents a few weeks or months after the initial procedure. We present a report of three such cases of sclerosing lipogranuloma involving the eyelid, which occurred following a sinonasal surgery where nasal packing using petroleum jelly was performed. The typical clinical course and the classical histopathological features are highlighted. All cases were diagnosed by histopathological examination as sclerosing lipogranuloma. Complete surgical removal resulted in complete resolution on 1 month follow-up. The diagnosis is based on a high degree of suspicion following a detailed history of prior use of lipid-based products for nasal packing following endonasal surgery. Histopathology is diagnostic. Surgical excision is the treatment of choice, however, due to its infiltrative nature, it may be difficult to obtain a complete cure. 2015 BMJ Publishing Group Ltd.

Experimental brain edema was produced by either cold injury or TET (triethyl-tin) intoxication in twenty-five Wistar rats, weighing about 250 g each, and then analyzed using MRI (magnetic resonance imaging). The MRI was carried out with a 0.1 Tesla clinical apparatus (Asahi Mark J), using a special coil (7 cm in diameter) devised for small animals in order to obtain SR, SE, IR, and calculated T/sub 1/ and T/sub 2/ images. A dose of 0.5 mmol/kg of Gd-DTPA was injected intravenously for the cold-injury edema, and MRIs of the rat brains were started immediately and obtained successively for 3 hours. MRI showed spatial resolution sufficient to differentiate the cortex from the caudate nucleus, even in such a small rat brain. Rat brains with TET intoxication (cytotoxic edema) showed a marked prolongation of T/sub 1/ and T/sub 2/ in the white matter. Consequently, the TET-intoxication images reflected these characteristic findings. Cold-induced edema showed an increased signal intensity in the injured cortex, the white matter, and the opposite white matter when compared with a normal brain. These changes correlate well with the previously reported in vitro data. When Gd-DTPA was administered to the rats with cold-induced edema, the signal intensity of the cold-injury lesion was significantly reduced. These changes were clearly demonstrated by the calculated T/sub 1/ images. To two rats we administered a dose of 0.5 mmol/kg of Gd-DTPA; The T/sub 1/ values for the cold-injury lesions, before and after the injection, were about 445 msec and about 200 msec respectively. These studies were useful not only in evaluating brain edema, but also in analysing the effect of Gd-DTPA on the brain edema.

To elucidate the sequential radiologic manifestations of reperfusion edema after lung transplantation. The study group comprised five consecutive lung transplant recipients (M:F=3:2;mean age; 47.5 years) who between July 1996 and April 2002 underwent lung transplantation procedures (four, unilateral; one, bilateral) at our institution. We retrospectively reviewed the serial postoperative radiographs obtained and characterized the lung infiltrates. Lung infiltrates compatible with reperfusion edema were present in all patients (5/5). Reperfusion edema appeared on day 1 in four, and by day 2 in the other. In all transplanted lungs, infiltrates were found in the perihilar and basilar regions, and were scored as maximal on day 1 in one, day 3 in two, day 4 in one and day 5 in the other. The recognition of sequential radiological manifestations helps identify recognition of reperfusion edema after lung transplantation

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 Radiology residents interpreted chest radiographs more accurately than did EM and IM residents. Residents were able to more accurately identify 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.

Between 1969 and 1985, 30 patients with carcinomas of the eyelid were treated by radiation, including 19 primary cases and 11 secondary cases. The latter were less controlable than the former. According to histology, there were 21 squamous cell carcinomas, 6 basal cell carcinomas and 3 adenocarcinomas. Among the 21 patients with squamous cell carcinomas, 5 had local recurrences, 10 had lymph node metastasis and 3 had distant metastasis. Patients with other histological classifications had no local recurrences, except for one who received incomplete therapy due to diabetes. Almost all of the controlled patients with squamous cell carcinomas were treated with a TDF value greater than 90. Although the visual function was damaged by irradiation in seven patients, the lesions of 6 of them were too advanced to avoid radiation injuries. (author)

Glufosinate-ammonium (GLA) is a broad-spectrum herbicide used worldwide. We report a patient who attempted suicide by ingesting a liquid herbicide containing GLA. A diffusion-weighted MRI showed cytotoxic edema in the hippocampus as well as vasogenic edema in the striata. To our knowledge, vasogenic edema caused by GLA-containing herbicide involving the striatum has not been reported in association with cytotoxic edema in the hippocampus. We assume that this herbicide affected the central nervous system via different mechanisms to produce both cytotoxic and vasogenic edema in the same patient.

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.

Negative pressure pulmonary edema revisited: Pathophysiology and review of management

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 Primary intestinal lymphangiectasia (PIL or Waldmann's disease is a rare protein-losing gastroenteropathy of unknown etiology. Less than 200 cases have been reported globally. Patients may be asymptomatic or present edema, lymphedema, diarrhea, ascites and other manifestations. We report two pediatric cases with PIL with extremely different outcome in a 3-year follow-up period. The first patient presented with persistent diarrhea, hypoalbuminemia and failure to thrive, while the second patient presented with an abrupt eyelid edema. Hypoproteinemia was the common laboratory finding for the two patients and upper gastrointestinal endoscopy established the diagnosis. The first patient relapsed five times during the follow-up period after the diagnosis had been made and required intravenous albumin administration and micronutrient supplementation. The second patient revealed normal gastrointestinal endoscopy 4 months after the diagnosis had been established; he followed an unrestricted diet and remained asymptomatic throughout the follow-up period. PIL can be either severe, affecting the entire small bowel, leading to lifetime disease, or sometimes affects part of the small bowel, leading to transient disorder.

Fujii, K.

1994-01-01

To evaluate the role of MR imaging in the diagnosis of edema, various types of edema were examined with MR imaging. MR imaging of edematous limbs was performed on 60 patients (lymphatic edema 48, nonlymphatic edema 12) using. T1-and T2-weighted spin-echo and shot inversion time inversion recovery sequences. Thickness and signal intensity of the cutis, subcutis and subfascia were evaluated in the images. In all 48 cases with lymphatic edema, trabecular structures suggesting dilated collateral lymphatic vessels were observed in the swollen subcutis. Two cases with nephrotic syndrome showed similar findings. In 6 cases with venous edema, fatty intensity was found in the subfascia. In the remaining 4 cases, the subcutis exhibited only water intensity. MR imaging is a potential contributor to the diagnosis of various edematous diseases. (orig./MG)

Scalp edema is an uncommon and striking finding in children that may alarm both parents and physicians. The objectives of this case report were to raise awareness among pediatric emergency physicians of the unusual presentation of sunburn as scalp edema. We present the case of an eight-year-old boy with sunburn of the head, presenting with scalp and face edema. Pitting edema and erythema were dominant on the forehead. Shaving of the boy's head the day before the symptoms was the most striking issue, and the sunburn healed gradually without any complications. Healthcare professionals should be aware of this condition, and the diagnosis of sunburn must be kept in mind in otherwise healthy-looking patients with a unique history.

Computed tomography (CT) is the first noninvasive method available for directly visualizing brain edema in man. On CT scans perifocal edema is shown as an area of low density surrounding a lesion. The purpose of this report is to evaluate the effect of corticosteroids on brain edema as seen by CT (HITACHI CT-H 250). Nine patients with brain-tumor and one with brain-abscess were treated with betamethasone for about ten days (dosage started with 12 - 16 mg/day, and tapered). In eight cases, and improvement in the neurological findings was observed. An impressive reduction of peritumoral edema was shown on CT scans in six of these eight cases. There was, however, no significant correlation between the degree of the reduction of edema on CT and that of the improvement in neurological findings. The mode of the CT number in the region of edema did not differ significantly between pre- and post-steroid treatment in the cases showing a recognizable reduction of edema on CT. This failure to change is probably due to the insufficient mechanical accuracy of the CT scanner at the present stage of technology. Through our experiences, it seems that CT is one of the most promising tools for a dynamic study of brain edema in man. (author)

Sobel, Rachel K; Carter, Keith D; Allen, Richard C

2012-09-01

Periorbital edema is a common problem that deserves scrutiny. Although a variety of healthcare providers may see this clinical entity, ophthalmologists are often consulted along the way toward diagnosis. It can challenge even the most astute clinicians. A diagnosis may reveal merely a bothersome issue or potentially a sight-threatening or life-threatening problem. Comprehensive reviews on this topic are scarce. Textbooks are brief. There are, however, many studies in the scientific literature of notable cases of periorbital edema. The causes generally fall into the categories of infectious, inflammatory or tumors, medication related, and postsurgical or trauma. This article synthesizes the current literature on the topic with a case series from our institution. It aims to provide a thorough resource for all practitioners to make the prospect of triaging, diagnosing, and treating periorbital edema less daunting.

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

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.

1998-01-01

To evaluate the frequency of peritumoral bone marrow(BM) edema accompanying benign giant cell tumor(GCT) of the appendicular bone by magnetic resonance(MR) imaging and to correlate MRI findings with those of plain radiography and bone scintigraphy. Eighteen cases of pathologically proven benign GCT of the appendicular bone were retrospectively analyzed using MR images, plain radiographs and bone scintigrams. A plain radiography was available in 15 cases, and a scintigram in six. Marrow edema was defined as peritumoral signal changes which were of homogeneous intermediate or low signal intensity(SI) onT1WI and high SI on T2WI, relative to the SI of normal BM, and homogeneous enhancement on Gd-DTPA -enhanced T1WI. The transition zone, sclerotic margin and aggressiveness of the lesion were assessed on the basis of plain radiographs. BM edema seen on MR images was correlated with plain radiographic and scintigraphic findings. 1. Peritumoral BM edema was seen on MR images in 10 of 18 cases (55.5%). 2. In 8 of 15 cases for which plain radiographs were available, MR imaging revealed BM edema. In six of these eight, transition zone was wide, while in two it was narrow. Six of seven patients without marrow edema showed a wide transition zone, and in one this was narrow. There was significant correlation between BM edema shown by MR imaging and the transition zone seen on plain radiographs (x 2 , p<0.05). But the aggressiveness shown by plain radiographs correlated only marginally while the presence of sclerotic rim did not correlate. 3. All six cases for which a bone scintigram was available showed an extended uptake pattern. In five of the six, MR imaging revealed edema. Peritumoral BM edema was frequently seen (55.5%) in the GCTs of appendicular bone; it was more often shown in association with a wide transition zone by plain radiographs.=20

Computed tomographic (CT) examinations were performed in 94 lesions of 50 patients with metastatic brain tumors. Peritumoral edema (A E ) and tumor area (A T ) were measured using the planimetric method on the CT scan films that demonstrated maximum size of the tumor. Then, the volume of the peritumoral edema (V E ) and the surface area of the tumor (S T ) were claculated from these data. Eighty-three brain lesions from lung cancers were subdivided into 49 adenocarcinomas, 11 squamous cell carcinomas, 16 small cell carcinomas and 7 large cell carcinomas. Eleven metastatic tumors from breast cancers were all adenocarcinomas. There was statistical correlation between the surface area of tumor and the volume of the peritumoral edema for the adenocarcinoma (r=0.4043, p E /S T ratios in small cell carcinomas were smaller then those in non-small cell carcinomas, when the volume of the tumor was larger than 10 mm 3 . Accordingly, we suggest that the volume of the peritumoral edema in the small cell carcinoma is generally smaller than that in others. (author)

Laparoscopy to evaluate scrotal edema during peritoneal dialysis.

Haggerty, Stephen P; Jorge, Juaquito M

2013-01-01

Acute scrotal edema is an infrequent complication in patients who undergo continuous ambulatory peritoneal dialysis (CAPD), occurring in 2% to 4% of patients. Inguinal hernia is usually the cause, but the diagnosis is sometimes confusing. Imaging modalities such as computed tomographic peritoneography are helpful but can be equivocal. We have used diagnostic laparoscopy in conjunction with open unilateral or bilateral hernia repair for diagnosis and treatment of peritoneal dialysis (PD) patients with acute scrotal edema. TECHNIQUE AND CASES: Three patients with acute scrotal edema while receiving CAPD over the span of 7 years had inconclusive results at clinical examination and on diagnostic imaging. All patients underwent diagnostic laparoscopy that revealed indirect inguinal hernia, which was concomitantly repaired using an open-mesh technique. Diagnostic laparoscopy revealed the etiology of the scrotal edema 100% of the time, with no complications, and allowed concomitant repair of the hernia. One patient had postoperative catheter outflow obstruction, which was deemed to be unrelated to the hernia repair. Diagnostic laparoscopy is helpful in confirming the source of acute scrotal edema in CAPD patients and can be performed in conjunction with an open-mesh repair with minimal added time or risk.

Purpose: To derive a rigorous analytic solution to the dosimetric effects of prostate edema so that its impact on the conventional pre-implant and post-implant dosimetry can be studied for any given radioactive isotope and edema characteristics. Methods and Materials: The edema characteristics observed by Waterman et al (Int. J. Rad. Onc. Biol. Phys, 41:1069-1077; 1998) was used to model the time evolution of the prostate and the seed locations. The total dose to any part of prostate tissue from a seed implant was calculated analytically by parameterizing the dose fall-off from a radioactive seed as a single inverse power function of distance, with proper account of the edema-induced time evolution. The dosimetric impact of prostate edema was determined by comparing the dose calculated with full consideration of prostate edema to that calculated with the conventional dosimetry approach where the seed locations and the target volume are assumed to be stationary. Results: A rigorous analytic solution on the relative dosimetric effects of prostate edema was obtained. This solution proved explicitly that the relative dosimetric effects of edema, as found in the previous numerical studies by Yue et. al. (Int. J. Radiat. Oncol. Biol. Phys. 43, 447-454, 1999), are independent of the size and the shape of the implant target volume and are independent of the number and the locations of the seeds implanted. It also showed that the magnitude of relative dosimetric effects is independent of the location of dose evaluation point within the edematous target volume. It implies that the relative dosimetric effects of prostate edema are universal with respect to a given isotope and edema characteristic. A set of master tables for the relative dosimetric effects of edema were obtained for a wide range of edema characteristics for both 125 I and 103 Pd prostate seed implants. Conclusions: A rigorous analytic solution of the relative dosimetric effects of prostate edema has been

Amiloride-Sensitive Sodium Channels and Pulmonary Edema

Directory of Open Access Journals (Sweden)

Mike Althaus

2011-01-01

Full Text Available The development of pulmonary edema can be considered as a combination of alveolar flooding via increased fluid filtration, impaired alveolar-capillary barrier integrity, and disturbed resolution due to decreased alveolar fluid clearance. An important mechanism regulating alveolar fluid clearance is sodium transport across the alveolar epithelium. Transepithelial sodium transport is largely dependent on the activity of sodium channels in alveolar epithelial cells. This paper describes how sodium channels contribute to alveolar fluid clearance under physiological conditions and how deregulation of sodium channel activity might contribute to the pathogenesis of lung diseases associated with pulmonary edema. Furthermore, sodium channels as putative molecular targets for the treatment of pulmonary edema are discussed.

Ultrasonography (US) is useful for visual detection of edematous tissues to assess subcutaneous echogenicity. However, visualization of subcutaneous echogenicity is interpreted differently among operators because the evaluation is subjective and individual operators have unique knowledge. This study objectively assessed leg edema using US with a gel pad including fat for normalization of echogenicity in subcutaneous tissue. Five younger adults and four elderly people with leg edema were recruited. We compared assessments of US and limb circumference before and after the intervention of vibration to decrease edema in younger adults, and edema prior to going to sleep and reduced edema in the early morning in elderly people. These assessments were performed twice in elderly people by three operators and reliability, interrater differences, and bias were assessed. For US assessment, echogenicity in subcutaneous tissue was normalized to that of the gel pad by dividing the mean echogenicity of subcutaneous tissue by the mean echogenicity of the gel pad. In younger adults, the normalized subcutaneous echogenicity before the intervention was significantly higher than that after the intervention. In elderly people, echogenicity indicating edema was significantly higher than that after edema reduction. Edema was detected with accuracy rates of 76.9% in younger adults and 75.0% in elderly people. Meanwhile, limb circumference could be used to detect edema in 50.0% of healthy adults and 87.8% of elderly people. The intra-reliability was excellent (intraclass correlation coefficient > 0.9, p 0.7, p edema with high reliability. Therefore, this method has the potential to become a new gold standard for objective assessment of leg edema in clinical practice. PMID:28792959

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.

Memory, as measured by changes in an animal's behavior some time after learning, is a reflection of many processes. Here, using a trace paradigm, in mice we show that de novo protein synthesis is required for acquisition, consolidation, reconsolidation, and extinction of classically conditioned eyelid responses. Two critical periods of protein synthesis have been found: the first, during training, the blocking of which impaired acquisition; and the second, lasting the first 4 h after training, the blocking of which impaired consolidation. The process of reconsolidation was sensitive to protein synthesis inhibition if anisomycin was injected before or just after the reactivation session. Furthermore, extinction was also dependent on protein synthesis, following the same temporal course as that followed during acquisition and consolidation. This last fact reinforces the idea that extinction is an active learning process rather than a passive event of forgetting. Together, these findings demonstrate that all of the different stages of memory formation involved in the classical conditioning of eyelid responses are dependent on protein synthesis.

Massive vulvar edema in a woman with preeclampsia preceded the development of massive ascites and impending eclampsia. A 17-year-old preeclamptic, primiparous woman was admitted with preeclampsia and massive vulvar edema. Other causes were excluded. The vulvar edema increased as the blood pressure and ascites increased, and a severe headache developed. Cesarean section for increasing preclampsia was performed. In the puerperium, the blood pressure improved and vulvar edema resolved. The clinical picture of the vulvar edema correlated with the severity of the preeclampsia. The presence of vulvar edema in women with preeclampsia should indicate immediate admission to the hospital. These patients must be considered as at high risk, and close monitoring must be instituted. In our case, vulvar edema preceded massive ascites development. We assume a common development mechanism for these signs in preeclampsia, due mainly to increased capillary permeability and hypoalbuminemia. The attending physician must be prepared for immediate delivery and possible preeclampsia complications in these patients.

Leucomycin-induced acute generalized exanthematous pustulosis complicated with pitting edema of the legs

Full Text Available Acute generalized exanthematous pustulosis (AGEP is characterized by fever, sterile nonfollicular pustules, and neutrophilia. More than 90% of cases of AGEP are induced by antibiotics such as aminopenicillins and macrolides. However, little is known about the side effects associated with leucomycin. To the best of our knowledge, the following case is the first one reporting leucomycin-induced AGEP. The case presented here is of a 43-year-old man who suffered from generalized pustulosis and severe leg edema 2 days after taking leucomycin for an upper respiratory tract infection. With discontinuation of leucomycin and a short course of systemic steroid treatment, these symptoms were gradually relieved.

Injuries such as traumatic brain injury and stroke can result in increased blood-brain barrier permeability. This increase may lead to water accumulation in the brain tissue resulting in vasogenic edema. Although the initial injury may be localised, the resulting edema causes mechanical damage and compression of the vasculature beyond the original injury site. We employ a biphasic mixture model to investigate the consequences of blood-brain barrier permeability changes within a region of brain tissue and the onset of vasogenic edema. We find that such localised changes can indeed result in brain tissue swelling and that the type of damage that results (stress damage or strain damage) depends on the ability of the brain to clear edema fluid.

Callen, Andrew L; Illangasekare, Tushani; Poder, Liina

Massive ovarian edema is a benign clinical entity, the imaging findings of which can mimic an adnexal mass or ovarian torsion. In the setting of acute abdominal pain, identifying massive ovarian edema is a key in avoiding potential fertility-threatening surgery in young women. In addition, it is important to consider other contributing pathology when ovarian edema is secondary to another process. We present a case of a young woman presenting with subacute abdominal pain, whose initial workup revealed marked enlarged right ovary. Further imaging, diagnostic tests, and eventually diagnostic laparoscopy revealed that the ovarian enlargement was secondary to subacute appendicitis, rather than a primary adnexal process. We review the classic ultrasound and MRI imaging findings and pitfalls that relate to this diagnosis.

Drowning stars: reassessing the role of astrocytes in brain edema.

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.

Myofibroma is a neoplasia of myofibroblasts that can be solitary or multiple and it is found most commonly in the head & neck region including scalp, forehead, parotid region and oral cavity. In the eyelid it is rarely reported. It has a benign course in the solitary form and fatal in its multiple form. A 4 month male infant referred to Farabi hospital -the referral center for eye diseases- with a 2 month history of a mass in his eyelid with gradual enlargement with no other complaints. The only abnormal physical finding was a 2.5 cm mass in the eyelid. This mass was excised and sent to the hospital pathology laboratory. When confronting a spindle cell lesion with a nodular or multinodular growth pattern which appears biphasic due to alteration of light and dark staining areas, the surgical pathologist should think to the possibility of myofibroma. Its pattern of growth and architecture rules out the other differential diagnoses like nodular fasciitis, fibrous histiocytoma, infantile fibromatosis, and peripheral primitive neuroectodermal tumor, mesenchymal chondrosarcoma, malignant hemangiopericytoma, juvenile fibrosarcoma and poorly differentiated synovial sarcoma. In difficult cases immunohistochemical staining is helpful that is Vimentin & Actin positivity & Desmin, CK, EMA & S100 negativity.

PATHOGENESIS OF OPTIC DISC EDEMA IN RAISED INTRACRANIAL PRESSURE

Science.gov (United States)

Hayreh, Sohan Singh

2015-01-01

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

O objetivo deste artigo foi relatar um caso de edema pulmonar por pressão negativa (EPPN após extubação traqueal com sucesso terapêutico, após uso de ventilação mecânica não-invasiva com pressão positiva. RELATO DO CASO: Paciente do sexo feminino, 22 anos, foi submetida à colecistectomia aberta. Os exames pré-operatórios encontravam-se sem alterações. Imediatamente após extubação a paciente apresentou dispnéia súbita e crepitações pulmonares. Foi iniciado tratamento para edema agudo de pulmão com oxigenoterapia sob máscara de Venturi, elevação do tórax e diurético. A paciente foi encaminhada a UTI devido a falha no tratamento. Ao chegar a UTI foi iniciada ventilação mecânica não-invasiva (VMNI com pressão de suporte (15 cmH2O e pressão expiratória final positiva (5 cmH2O com resolução dos sintomas. A paciente foi mantida em observação por mais 24 horas depois do evento com boas condições e recebeu alta para o quarto sem sintomas. CONCLUSÕES: O EPPN é uma entidade de difícil diagnóstico e deverá ser observada sempre que os pacientes evoluem com sinais e sintomas de insuficiência respiratória pós-extubação. Esta paciente se beneficiou de VMNI, mas caso haja falha terapêutica, a intubação traqueal e o suporte ventilatório mecânico invasivo deverão ser instituídos para melhor oxigenação dos pacientes.BACKGROUND AND OBJECTIVES: Negative pressure pulmonary edema after acute upper airway obstruction is a well-described event, thought infrequently diagnosed and reported.

Diabetes is a serious chronic condition,which increase the risk of cardiovascular diseases,kidney failure and nerve damage leading to amputation.Furthermore the ocular complications include diabetic macular edema,is the leading cause of blindness among adults in the industrialized countries.Today,blindness from diabetic macular edema is largely preventable with timely detection and appropriate interventional therapy.The treatment should include an optimized control of glycemia,arterial tension,lipids and renal status.The photocoagulation laser is currently restricted to focal macular edema in some countries,but due the high cost of intravitreal drugs,the use of laser treatment for focal and diffuse diabetic macular edema(DME),can be valid as gold standard in many countries.The intravitreal anti vascular endothelial growth factor drugs(ranibizumab and bevacizumab),are indicated in the treatment of all types of DME,but the correct protocol for administration should be defined for the different Retina Scientific Societies.The corticosteroids for diffuse DME,has a place in pseudophakic patients,but its complications restricted the use of these drugs for some patients.Finally the intravitreal interface plays an important role and its exploration is mandatory in all DME patients.

1996-01-01

Objective. Radiation therapy is often used to treat bone und soft tissue neoplasms, and commonly results in soft tissue edema in the radiation field. However, the time course, distribution and degree of this edema have not been well characterized. Our study was carried out to better define these features of the edema seen following neutron and photon radiation therapy. Results. In general, soft tissue signal intensity in the radiation field initially increased over time, peaking at about 6 months for neutron-treated patients and at about 12-18 months for photon-treated patients. Signal intensity then decreased slowly over time. However, at the end of the follow-up period, signal intensity remained elevated for most patients in both groups. Signal intensity in a particular tissue was greater and tended to persist longer on STIR sequences than on T2-weighted sequences. Survival analysis of signal intensity demonstrated much longer edema survival times for neutron-treated patients than for photon-treated patients. Signal intensity increase in the intramuscular septa persisted for much longer than for fat or muscle. A mild increase in size was noted in the subcutaneous fat and intramuscular septa. Muscle, on the other hand, showed a decrease in size following treatment. This was mild for the photon-treated group and more marked for the neutron-treated group. Conclusions. There is a relatively wide variation in the duration and degree of post-irradiation edema in soft tissues. This edema seems to persist longer in the intramuscular septa than in fat or muscle. Although the duration of follow-up was limited, our study suggests that this edema resolves in roughly half the photon-treated patients within 2-3 years post-treatment and in less than 20% of neutron-treated patients by 3-4 years post-treatment. Muscle atrophy was seen in both photon- and neutron-treated patients, but was more severe in the neutron-treated group. (orig./vhe). With 4 figs

2016-01-01

Full Text Available Background/Aim. Upper limb lymphedema is one of the most frequent chronic complications after breast cancer treatment with a significant impact on the upper extremity function and quality of life (QoL. The aim of this study was to estimate health-related quality of life (HRQoL in patients with breast-cancer-related lymphedema and its correlation with upper limb function and the size of edema. Methods. The cross-sectional study included 54 breast-cancer-related lymphedema patients. The quality of life was evaluated by the Short Form 36-Item Health Survey (SF-36. Upper limb function was assessed by the Quick Disability of the Arm, Shoulder and Hand questionnaire (Quick DASH. The size of lymphedema was determined by the arm circumference. Results. The higher HRQoL score was assessed for mental health (47.0 ± 12.2 than for physical one (42.2 ± 7.5. The highest values of SF-36 were found in the domains of Mental Health (67.7 ± 22.9 and Social Function (70.1 ± 23.1. The lowest scores were registered in the domains of Role Physical (46.9 ± 39.1 and General Health (49.3 ± 20.1. Upper extremity function statistically significantly correlated with the domains Role Physical, Bodily Pain and Physical Composite Summary and also, with the domain Role Emotional (p 0.05. Conclusions. Physical disability in patients with breast cancer-related lymphedema influences quality of life more than mental health. Upper limb function has a significant impact on quality of life, not only on the physical, but also on the mental component. The presence of breast-cancer-related lymphedema certainly affects upper limb function and quality of life, but in this study no significant correlation between the size of edema and quality of life was found.

For the purpose of treating brain tumors satisfactorily with steroids, CT findings of brain tumors were analyzed, and pathogenesis of peritumoral edema and supposed effects of steroids were investigated. The degree of peritumoral edema and contrast enhancement and their relationship were analyzed in total 201 patients with brain tumors (gliomas, meningiomas, and metastatic brain tumors). As a result, significant peritumoral edema was recognized in 59% of patients with metastatic brain tumors, 46% of patients with glioma, and 34% of patients with meningioma. As a rule, there was a relationship between peritumoral edema and malignancy or localization of braiin tumors. Severe peritumoral edema was observed in malignant supratentorial tumors (over 60%), but peritumoral edema which was found in infratentorial tumors benign gliomas was mild. The degree of contrast enhancement differed according to tumors, and there was not always a relationship between the degree of contrast enhancement and malignancy or localization of brain tumors. CT findings of brain tumors after the administration of steroids showed decrease in the degree of contrast enhancement. Judging from the effect of steroids to inhibit increased vascular permeability associated with brain edema, like CT findings of peritumoral edema, the degree of contrast enhancement which probably expressed vascularity or vascular permeability seemed to be important in deciding the indications for steroid administration.

Forced eyelid closure test (FECT) is a clinical screening test developed from the original Cogan lid twitch (CLT) sign to assist in the diagnosis of ocular myasthenia gravis (OMG), We evaluated the sensitivity and specificity of FECT compared with CLT and benchmarked to standard diagnostic tests. This study was a retrospective chart review of 48 patients using electronic medical records of those that presented with ptosis and/or diplopia at Doheny Eye Institute, University of California, Los Angeles between February 2015 and April 2016. Patients without FECT testing were excluded. FECT and CLT results, and final diagnosis were recorded. To perform FECT, the patient was asked to squeeze his or her eyelids shut for 5-10 seconds then open quickly and fixate in primary position. The excessive upward overshoot of eyelids movement indicated a positive FECT. The test was performed by a neuro-ophthalmologist before establishing the diagnosis. Patients who had equivocal test results and/or inconclusive final diagnosis were excluded. Of the 48 patients studied, 18 patients (37.5%) had positive FECT; 15 of whom had a final diagnosis of OMG (83.3%). Of the 30 patients with negative FECT, 1 had OMG (3.3%). Of the 48 patients, 35 patients also had a documented CLT result (72.9%). CLT was positive in 11 of these 35 patients (31.4%), and 9 of these 11 had OMG (81.8%). Of the 24 patients with negative CLT, 2 of them had OMG (8.3%). Sensitivity and specificity of FECT were 94% and 91% (joint 95% confidence region: sensitivity × specificity = [0.70, 1] × [0.75, 1]). The relative true-positive fraction (rTPF) between FECT and CLT was 1.15; the relative false-positive fraction was 1.31. FECT is a simple clinical screening test with good sensitivity and specificity for OMG.

The spreading of focal brain edema induced by ultraviolet irradiation

Ferszt, R.; Neu, S.; Cervos-Navarro, J.; Sperner, J.

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

Pathophysiology, Evaluation, and Management of Edema in Childhood Nephrotic Syndrome.

Science.gov (United States)

Ellis, Demetrius

2015-01-01

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.

Cellular characterization of the peritumoral edema zone in malignant brain tumors

Engelhorn, T.; Schwarz, M.A.; Savaskan, N.E.

2009-01-01

Brain edema is a hallmark of human malignant brain tumors and contributes to the clinical course and outcome of brain tumor patients. The so-called perifocal edema or brain swelling imposes in T2-weighted MR scans as high intensity areas surrounding the bulk tumor mass. The mechanisms of this increased fluid attraction and the cellular composition of the microenvironment are only partially understood. In this study, we focus on imaging perifocal edema in orthotopically implanted gliomas in rodents and correlate perifocal edema with immunohistochemical markers. We identified that areas of perifocal edema not only include the tumor invasion zone, but also are associated with increased glial fibrillary acidic protein (GFAP) and aquaporin-4 expression surrounding the bulk tumor mass. Moreover, a high number of activated microglial cells expressing CD11b and macrophage migration inhibitory factor (MIF) accumulate at the tumor border. Thus, the area of perifocal edema is mainly dominated by reactive changes of vital brain tissue. These data corroborate that perifocal edema identified in T2-weighted MR scans are characterized with alterations in glial cell distribution and marker expression forming an inflammatory tumor microenvironment.

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.

Full Text Available Soft tissue deflation and descent have long been implicated in the pathogenesis of facial aging. In the periorbital area, the upper orbital region is thought to change by descent of the eyebrow, as well as deflation of brow fat. While the understanding of the aging changes in the upper eyelid region are relatively simple, the lower eyelid poses a myriad of aging changes, each demanding a specific management plan. These can be best described in terms of elevations, or 'Hills' and hollows, or 'Valleys'. This article simplifies the understanding of the lower eyelid in the light of anatomical knowledge, and available literature. It forms a basis of easy diagnosis and treatment of the soft tissue changes in the lower eyelid and malar region.

Magnetic resonance imaging of cold injury-induced brain edema in rats

Houkin, Kiyohiro; Abe, Hiroshi; Hashiguchi, Yuji; Seri, Shigemi.

1996-01-01

The chronological changes of blood-brain barrier disruption, and diffusion and absorption of edema fluid were investigated in rats with cold-induced brain injury (vasogenic edema) using magnetic resonance imaging. Contrast medium was administered intravenously at 3 and 24 hours after lesioning as a tracer of edema fluid. Serial T 1 -weighted multiple-slice images were obtained for 180 minutes after contrast administration. Disruption of the blood-brain barrier was more prominent at 24 hours after lesioning than at 3 hours. Contrast medium leaked from the periphery of the injury and gradually diffused to the center of the lesion. Contrast medium diffused into the corpus callosum and the ventricular system (cerebrospinal fluid). Disruption of the blood-brain barrier induced by cold injury was most prominent at the periphery of the vasogenic edema. Edema fluid subsequently extended into the center of the lesion and was also absorbed by the ventricular system. Magnetic resonance imaging is a useful method to assess the efficacy of therapy for vasogenic edema. (author)

Demodex infestations cause blepharitis and are difficult to treat. Recently, a new type of eyelid wipes with terpenoids has been found effective. We aim to evaluate patient satisfaction after short-term use and compare two teaching modalities on the techniques of use. Eligible participants were taught to use eyelid wipes (Cliradex ® ) by either live or online video demonstration based on random allocation. Participants used the wipes twice daily for a week. All participants had prior evaluation of socioeconomic status, dry eye symptoms, and meibomian gland features. After 1 week, competence of use was assessed by participants showing their technique to the investigator, and a questionnaire on comfort, ease, and convenience of use was administered. Higher scores indicate greater satisfaction, and these levels are compared among the two teaching modalities using chi square. A total of 50 participants were recruited, with a mean age of 42±16 years, and 88% of the participants were females. Overall, median comfort level was 4.0 (range: 1-6), ease level was 5.0 (3-6), and convenience level was 5.0 (2-6). Median stinging was 2.0 (1-4), which corresponded to some but mild stinging. The median competence level was 4.0 (2-4), which corresponded to excellent competence. These satisfactory levels (ease, comfort, and convenience) experienced were not significantly associated with different socioeconomic indicators, that is, housing type, income, highest education level, and were not different between teaching methods ( p >0.05). Short-term use of Cliradex eyelid wipes seems to be acceptable to most people. The teaching instructions before using these wipes were equally effective - whether live or online video demonstration was used.

International Nuclear Information System (INIS)

Shi Yuxin; Xu Jianfeng

2005-01-01

Objective: To semi-quantitatively evaluate the cerebral perfusion in the peritumoral brain edema of cerebral tumors using CT perfusion imaging. Methods: Twenty-one patients with peritumoral brain edema (including pathologically confirmed meningiomas n=4, metastasis n=10, gliomas n=7) were examined by CT perfusion imaging. The regional cerebral blood flow (rCBF), regional cerebral blood volume (rCBV), and mean transit time (MTT) were calculated for peritumoral brain edema and the contralateralwhite matter. The rCBF and rCBV were compared between peritumoral brain edema and the contralateral white matter. The mean ratios (edema/contralateral white matter) of rCBF and rCBV were compared among the three tumors. Results: The rCBF and rCBV of peritumoral brain edema were significantly lower than those of contralateral white matter in patients with meningiomas and metastasis (rCBF: t=2.92 and 3.82, P 0.05). The mean ratios (edema/contralateralwhite matter) of rCBF and rCBV were not significantly different between meningiomas and metastasis (t=0.23 and 0.73, P>0.05), but both of them were significantly lower than those of gliomas (t=3.05 and 3.37, P<0.01, 0.005). Conclusion: The rCBF and rCBV in peritumoral brain edema were significantly lower than those of contralateral white matter in patients with meningiomas and metastasis, while almost the same with or higher than those of contralateral white matter in patients with gliomas. CT perfusion can provide quantitative information of blood flow in peritumoral brain edema, and is useful in the diagnosis and follow-up of cerebral tumors. (authors)

Full Text Available Purpose: To report the efficacy of intravitreal dexamethasone implant in a patient with retinitis pigmentosa and bilateral cystoid macular edema unresponsive to topical carbonic anhydrase inhibitors. Case Report: A 36-year-old man with bilateral cystoid macular edema associated with retinitis pigmentosa that was unresponsive to topical carbonic anhydrase inhibitors underwent bilateral 0.7-mg intravitreal dexamethasone implants two weeks apart. Spectral domain optical coherence tomography revealed resolution of macular edema one week following each injection in both eyes and his visual acuity improved. However, macular edema recurred two months later in OS and three months later in OD. Second implant was considered for both eyes. No implant-related complication was experienced during the follow-up of seven months. Conclusion: Inflammatory process seems to play a role in retinitis pigmentosa. Intravitreal dexamethasone implant may offer retina specialists a therapeutic option especially in cases unresponsive to other treatment regimens in eyes with retinitis pigmentosa-related macular edema.

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.

Full Text Available Se estima que en el mundo hay 120 millones de diabéticos y que cada 15 años el número de estos se duplica. 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. Se realizó un estudio descriptivo-prospectivo de caso control, en el cual, el paciente constituyó su propio control. La muestra estuvo formada por 30 pacientes diabéticos, con diagnóstico de edema macular diabético que fueron candidatos a la aplicación del medicamento. Predominó el sexo femenino con más de 6 años de edad, a pesar que se mejora la agudeza visual, esta no se correspondía con la disminución evidente del edema macular. Los pacientes que no tuvieron tratamiento láser previo, respondieron mejor al medicamento aplicado, como complicaciones postratamiento se presentó hipertensión ocular, involuci

Pathophysiology, Evaluation, and Management of Edema in Childhood Nephrotic Syndrome

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. PMID:26793696

To investigate the etiology of lower limb edema after arterial reconstruction, 12 patients (16 limbs) who underwent arterial reconstruction due to atherosclerosis obliterans were observed. There was no relationship between the severity of limb edema and serum factors (serum total proteins, albumin, BUN, and creatinine), ankle/brachial arterial pressure ratio, peripheral venous pressure or RI lymphoscintigraphy in the supine position. The lymphatic flow in RI lymphoscintigraphy at 3∼4 weeks after operation increased with statistically significant difference compared to the preoperative flow whether the patient was in the supine or upright position. Though there was no significant relationship between the severity of leg edema and postoperative lymphatic flow in the supine position, postoperative lymphatic flow in the upright position decreased as the severity of leg edema increased. Increased lymphatic flow in the follow-up period was associated with increased severity of leg edema in the upright position. It is concluded that postoperative leg edema is due to the damage to the lymphatic vessels during operation, and then the lymphatic channels cannot adapt to the increased lymphatic flow after the arterial reconstruction.

Steven M Couch

2008-11-01

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

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 -3 and 0.81 ± 0.09 x 10 -3 mm/s 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.)

Bone marrow edema of the knee joint is a frequent clinical picture in MR diagnostics. It can be accompanied by symptoms and pain in the joint. Diseases that are associated with bone marrow edema can be classified into different groups. Group 1 includes vascular ischemic bone marrow edema with osteonecrosis (synonyms: SONK or Ahlbaeck's disease), osteochondrosis dissecans, and bone marrow edema syndrome. Group 2 comprises traumatic or mechanical bone marrow edema. Group 3 encompasses reactive bone marrow edemas such as those occurring in gonarthrosis, postoperative bone marrow edemas, and reactive edemas in tumors or tumorlike diseases. Evidence for bone marrow edema is effectively provided by MRI, but purely morphological MR information is often unspecific so that anamnestic and clinical details are necessary in most cases for definitive disease classification. (orig.) [German] Das Knochenmarkoedem des Kniegelenks ist ein haeufiges Erscheinungsbild in der MR-Diagnostik. Es kann mit Symptomen und Schmerzen des Gelenks einhergehen.

Gruppe gehoeren das vaskulaer-ischaemische Knochenmarkoedem mit Osteonekrose (Synonyme SONK oder Morbus Ahlbaeck), die Osteochondrosis dissecans und das Knochenmarkoedemsyndrom, zur 2. Gruppe das traumatologische oder mechanische Knochenmarkoedem. In der 3. Gruppe werden reaktive Knochenmarkoedeme zusammengefasst wie bei Gonarthrose, postoperative Knochenmarkoedeme und reaktive Oedeme bei Tumor oder tumoraehnlichen Erkrankungen. Der Nachweis eines Knochenmarkoedems gelingt mit der MRT sehr sensitiv, die rein morphologische MR-Information ist jedoch oft unspezifisch, sodass anamnestische und klinische Informationen fuer die sichere Zuordnung einer Erkrankung in den meisten Faellen notwendig sind.

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.

Diagnosis of hydrostatic versus increased permeability pulmonary edema with chest radiographic criteria in critically ILL patients

International Nuclear Information System (INIS)

Aberle, D.R.; Wiener-Kronish, J.P.; Webb, W.R.; Matthay, M.A.

1987-01-01

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

[As opposed to normal subjects, eyelid position doesn't interfere with postural behavior in blind subjects].

A previous study has shown some behavioral differences in normal subjects depending on the position of the eyelids: the postural behavior was varying if the subject had the eyes open in darkness or the eyes closed. In this study, we explore the possible role of vision on this behavior. The postural behavior of 12 blind and nine visually impaired participants was studied during undisturbed upright stance. In this sample, no difference was found in the conditions eyes open in the dark and eyes closed: the observed behavior in blind and visually impaired subjects is different compared to normal sighted subjects who show a visual preference even in total darkness when the eyes are open. Our two groups (blind and visually impaired) actually show a difference on the median frequency of the centre of gravity displacements. Our results suggest an adaptive mechanism of the central nervous system in healthy individuals to predominantly weigh visual cues when the eyelids remain open. Good visual acuity and time seem to be necessary for this process.

Nonspecific edema is a syndrome which is caused by a metabolism disorder of sodium and water. The people who suffer with this are mostly women about 25 - 50 years old. When it happens periodic edema, abdominal distension acratia, and obesity accompany the disease. Through several means of examination, no organic disease was found in the heart, liver, or kidney. Now 16 edema cases have been irradiated with laser and the result is satisfactory. The results are reported in this paper.

Autofluorescence Imaging for Diagnosis and Follow-up of Cystoid Macular Edema

Directory of Open Access Journals (Sweden)

Nazanin Ebrahimiadib

Full Text Available Lipofuscin results from digestion of photoreceptor outer segments by the retinal pigment epithelium (RPE and is the principal compound that causes RPE fluorescence during autofluorescence imaging. Absorption of the 488-nanometer blue light by macular pigments, especially by the carotenoids lutein and zeaxanthin, causes normal macular hypo-autofluorescence. Fundus autofluorescence imaging is being increasingly employed in ophthalmic practice to diagnose and monitor patients with a variety of retinal disorders. In macular edema for example, areas of hyper-autofluorescence are usually present which are postulated to be due to dispersion of macular pigments by pockets of intraretinal fluid. For this reason, the masking effect of macular pigments is reduced and the natural autofluorescence of lipofuscin can be observed without interference. In cystic types of macular edema, e.g. cystoid macular edema due to retinal vein occlusion, diabetic macular edema and post cataract surgery, hyperautofluorescent regions corresponding to cystic spaces of fluid accumulation can be identified. In addition, the amount of hyper-autofluorescence seems to correspond to the severity of edema. Hence, autofluorescence imaging, as a noninvasive technique, can provide valuable information on cystoid macular edema in terms of diagnosis, followup and efficacy of treatment.

Diagnostic difficulties with intraorbital foreign bogies: A case report

As a result of trauma, a foreign body can enter the orbit and, via the orbital fissures, the cranial cavity. The most common are metallic, which are easily seen in X-rays, while low-density foreign bodies cause diagnostics problems. A 27-year old patient underwent trauma of the left orbit when walking in a forest. Twenty-four hours after the trauma the patient came to the ophthalmology outpatient clinic with complaints of inability to move the upper eyelid. The cause of the complaint was a 6-cm-long piece of wood within the orbit which was penetrating the middle cranial fossa via the upper orbital fissure. X-rays are the bases of diagnosing orbito-cranial injures and are a sufficient radiological method when the foreign body is metallic. CT is indispensable for the precise localization of low-density foreign bodies, the estimation of injury, and for diagnosis. CT scans are not typical for each foreign body. In this case, the hypo density of the wood was initially misinterpreted as an intra orbital air edema. (author)

Ex vivo confocal microscopy is a recent imaging technique for the perioperative control of skin tumour margins. Up to date, it has been used in the fluorescence mode and with vertical sections of the specimen margins. The aim of this study was to evaluate its use in the reflectance mode and with a horizontal ('en face') scanning of the surgical specimen in a series of basal cell carcinoma of the eyelid. Prospective consecutive cohort study was performed at the University Hospital of Saint-Etienne, France. Forty-one patients with 42 basal cell carcinoma of the eyelid participated in this study. Basal cell carcinomas were excised with a 2-mm-wide clinically safe margin. The surgical specimens were analysed under ex vivo confocal microscopy in the reflectance mode and with an en face scanning in order to control at a microscopic level if the margins were free from tumour invasion. Histopathogical examination was later performed in order to compare the results. Sensitivity and specificity of ex vivo confocal microscopy for the presence of tumour-free margins. Ex vivo confocal microscopy results were consistent with histopathology in all cases (tumour-free margins in 40 out of 42 samples; sensitivity and specificity of 100%). Ex vivo confocal microscopy in the reflectance mode with an 'en face' scanning can control tumour margins of eyelid basal cell carcinomas and optimize their surgical management. This procedure has the advantage on the fluorescent mode of not needing any contrast agent to examine the samples. © 2016 Royal Australian and New Zealand College of Ophthalmologists.

Posterior lumbar subcutaneous (PLS) edema on spine magnetic resonance (MR) images is a common incidental, though neglected finding. This study was undertaken to investigate the relations between PLS edema and pathologic conditions. Between January and December 2009, 138 patients with PLS edema, but without a spinal tumor or a history of recent surgery or trauma, and 80 infectious spondylitis patients without PLS edema were enrolled in this retrospective study. Available medical records and lumbar spine MR images were evaluated. The degree of edema was quantified using an arbitrary scoring system. Further, the correlations between the degree of edema and age, sex, body mass index (BMI), degeneration of posterior spinal structures (PSS) and infectious spondylitis were analyzed. Of the 93 cases with a calculable BMI, 61 (66%) had a BMI of > 23 kg/m2. Correlations between the degree of edema and sex, age and BMI grade were all statistically non-significant. Thirty-three cases (24%) had an underlying disease, such as heart problem, diabetes mellitus, liver cirrhosis, chronic renal failure, extra-spinal tumor or connective tissue disorder. The numbers of cases with infectious spondylitis and an idiopathic condition was 61 (44%) and 44 (32%), respectively. The grade of infectious spondylitis was not found to be significantly associated with the degree of edema (p = 0.084). In cases with an idiopathic condition, the correlation between the degree of edema and PSS degeneration was statistically significant (p = 0.042). Radiologists should not disregard PLS edema, because it is related to an underlying disease and thus may be of clinical significance.

Among them, 9 cases had clinical manifestations of sudden hip pain, 7 cases had limited ability of walking and hip movement;all patients had no obvious injury history, non of the female patients was pregnant. All patients were followed up from 3 to 12 months, the following-up were topped after MRI when the symptoms disappeared for 3 months. The MRI demonstrated diffuse bone marrow edema involving the femoral head, neck and the inter-trochanteric region, 13 hips of 10 patients with bone marrow edema included 6 cases in grade 1, 5 cases in grade 2,2 cases in grade 3; 9 hips with hip hydrarthrosis included 6 hips in grade I ,1 hip in grade II, 2 hips in grade III. After treatment for 3 to 12 months the hip symptoms of the patients disappeared and MRI images were normal. MRI is useful in defining the location and extent of proximal femur bone marrow edema syndrome.

Sequential observations of brain edema with proton magnetic resonance imaging and spectroscopy

International Nuclear Information System (INIS)

The purpose of this study was to assess the relationship between morphological and metabolic changes in brain edema using proton magnetic resonance systems. The serial changes during the first 24 hours in the cold-injury trauma rat brain model were investigated by proton magnetic resonance imaging ( 1 H MRI) and high-resolution proton MR spectroscopy ( 1 H MRS). We also analyzed the efficacy of AVS 1,2-bis (nicotinamide)-propane which can scavenge free radicals to the edema in this experiment. The edema was developing extensively via the corpus callosum in ipsi- and contralateral hemispheres as shown by gradually increased signal intensity on 1 H MRI. 1 H MRS initially showed accumulation of acetate and lactate, and transient increasing of glutamine. After 24 hours, the increased glutamine decreased below the control, alanine increased, and N-acetyl aspartate decreased with the edema development. AVS-treatment significantly suppressed edema development, increases of lactate and alanine and decreases of N-acetyl aspartate. We suggest that the cold-induced lesion contains anaerobic glycolysis deterioration and results in severe brain tissue breakdown. AVS is proved valuable for the treatment of this edema lesion. Clinical 1 H MRS showed prolonged lactate elevation and significant decreases of other metabolites in human ischemic stroke edema. In peritumoral edema, decreased N-acetyl aspartate gradually improved, and slightly elevated lactate disappeared after tumor removal. 1 H MRS feasibly characterizes the ischemic and peritumoral edema and makes a quantitative analysis in human brain metabolism. We believe the combined 1 H MRI and MRS study is a practical method to monitor the brain conditions and will make it easy and possible to find new therapeutic agents to some brain disorders.

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.)

Neurogenic mediators contribute to local edema induced by Micrurus lemniscatus venom

Science.gov (United States)

2017-01-01

Background/Aims Micrurus is one of the four snake genera of medical importance in Brazil. Coral snakes have a broad geographic distribution from the southern United States to Argentina. Micrurine envenomation is characterized by neurotoxic symptoms leading to dyspnea and death. Moreover, various local manifestations, including edema formation, have been described in patients bitten by different species of Micrurus. Thus, we investigated the ability of Micrurus lemniscatus venom (MLV) to induce local edema. We also explored mechanisms underlying this effect, focusing on participation of neuropeptides and mast cells. Methodology/Principal findings Intraplantar injection of MLV (1–10 μg/paw) in rats caused dose- and time-dependent edema with a peak between 15 min and 1 h after injection. MLV also induced degranulation of peritoneal mast cells (MCs). MC depletion by compound 48/80 markedly reduced MLV-induced edema. Pre-treatment (30 min) of rats with either promethazine a histamine H1 receptor antagonist or methysergide, a nonselective 5-HT receptor antagonist, reduced MLV-induced edema. However, neither thioperamide, a histamine H3/H4 receptor antagonist, nor co-injection of MLV with HOE-140, a BK2 receptor antagonist, altered the response. Depletion of neuropeptides by capsaicin or treatment of animals with NK1- and NK2-receptor antagonists (SR 140333 and SR 48968, respectively) markedly reduced MLV-induced edema. Conclusions/Significance In conclusion, MLV induces paw edema in rats by mechanisms involving activation of mast cells and substance P-releasing sensory C-fibers. Tachykinins NKA and NKB, histamine, and serotonin are major mediators of the MLV-induced edematogenic response. Targeting mast cell- and sensory C-fiber-derived mediators should be considered as potential therapeutic approaches to interrupt development of local edema induced by Micrurus venoms. PMID:29161255

2009-01-01

Background and objective: The assessment of bone marrow edema-like signal intensity in magnetic resonance imaging (MRI) in patients after osteochondral autograft transplantation (OCT) in the knee joint is a parameter of yet indefinite value. This study determines the prevalence of persistent edema-like signal intensity in OCT patients and evaluates the correlation between edema and morphological imaging findings of the graft and clinical pain symptoms. Materials and methods: In this longitudinal observational study, 10 patients after OCT were followed by MRI prospectively 1 month, 3 months, 6 months, 12 months, and 24 months post-operatively. All MR examinations were performed on a 1.0 T MR unit with the same protocol using a modified scoring system (magnetic resonance observation of cartilage repair tissue-MOCART) for evaluation. Edema-like signal intensity in and beneath the osteochondral graft was assessed in its prevalence and graded using a coronal short tau inversion recovery fast spin echo (STIR-FSE) sequence: grade 1, normal; grade 2, moderate (diameter 2 cm). The finding of edema-like signal intensity was correlated with graded parameters describing the morphology of the repair tissue assessed in a sagittal dual FSE sequence including: (a) surface of repair tissue: grade 1, intact; grade 2, damaged. (b) Cartilage interface: grade 1, complete; grade 2, incomplete. (c) Bone interface: grade 1, complete; grade 2, delamination. The finding of edema-like signal intensity was also correlated with the KOOS pain score assessing knee pain after 12 months. Results: Initially, after 1 month the prevalence of edema-like signal intensity was 70% (7/10 patients) and finally after 24 months 60% (6/10 patients). We found no significant relationship between the prevalence and degree of edema-like signal intensity and parameters describing the morphology of the repair tissue. Also the clinical pain score did not show significant correlation with edema. Conclusion

Radionuclide lymphoscintigraphy in limb edemas; La lymphoscintigraphie dans la pathologie lymphatique des membres: reflexions apres 20 ans d`utilisation

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

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.)

We attempted to evaluate the diagnostic usefulness of the degree of perilesional edema around intracerebral hematoma in predicting the underlying cause. This study included 54 patients with intracerebral hematoma for whom the underlying cause was confirmed by biopsy, radiological or clinical methods. Cases of subarachnoid hemorrhage, hemorrhagic transformation of cerebral infarction and intraventricular hemorrhage were excluded. The lesion size was defined as the average value of the longest axis and the axis perpendicular to this. The size of the perilesional edema was defined as the longest width of the edema. In all cases, the sizes of the lesion and edema were measured on the T2 weighted image. We defined the edema ratio as the edema size divided by the lesion size. 23 cases were diagnosed as intracerebral hemorrhage due to neoplastic conditions, such as metastasis (n=17), glioblastoma (n=5), hemangioblastoma (n=1). 31 cases were caused by non-neoplastic conditions, such as spontaneous hypertensive hemorrhage (n=23), arteriovenous malformation (n=4), cavernous angioma (n=3), and moya-moya disease (n=1). In fourteen cases, which were confirmed as malignant intracerebral hemorrhage, the edema ratio was more than 100%. Of the other cases, only 8 were confirmed as malignant intracerebral hemorrhage. It was found that the larger the edema ratio, the more malignant the intracerebral hemorrhage, and this result was statistically significant (p<0.001). Measurement of perilesional edema and the intracerebral hematoma ratio may be useful in predicting the underlying causes

In order to study the mechanism(s) underlying re-expansion edema, we measured the concentration of labeled albumin (RISA) in the extravascular, extracellular water (EVECW) of the lung as a measure of pulmonary vascular permeability. Re-expansion edema was first induced by rapid re-expansion of rabbit lungs that had been collapsed for 1 wk by pneumothorax. The RISA in EVECW was expressed as a fraction of its plasma concentration: (RISA)L/(RISA)PL. The volume of EVECW (ml/gm dry lung) was measured using a 24 Na indicator. Results in re-expansion edema were compared with normal control lungs and with oleic acid edema as a model of permeability edema. In re-expanded lungs, EVECW (3.41 +/- SD 1.24 ml/g) and (RISA)L/(RISA)PL 0.84 +/- SD 0.15) were significantly increased when compared with normal control lungs (2.25 +/- 0.41 ml/g and 0.51 +/- 0.20, respectively). Results in oleic acid edema (5.66 +/- 2.23 ml/g and 0.84 +/- 0.23) were similar to re-expansion edema. This suggested that re-expansion edema is due to increased pulmonary vascular permeability caused by mechanical stresses applied to the lung during re-expansion

Full Text Available Non melanomatous skin cancers constitute a major part of the cancers that occur in the face, especially in the darker skinned people. Surgical excision stays as the main modality of treatment in these giving very good cure rates. The major drawback of surgery is the resultant functional and esthetic deformity, which has been considerably reduced with proper application of reconstructive surgery principles. In order to achieve good outcome attention has to be given to understand the anatomy as well as tissue requirement at specific areas of the face. There is a great variation in the reconstructive methods in the different sites. This article reviews briefly the anatomy and methods of reconstruction available for the post cancer excisions involving the lips, eyelids and the auricle.

Diabetic Macular Edema: Current Understanding, Pharmacologic Treatment Options, and Developing Therapies.

Science.gov (United States)

Miller, Kevin; Fortun, Jorge A

2018-01-01

Diabetic retinopathy and diabetic macular edema comprise a major source of visual disability throughout the developed world. The etiology and pathogenesis of macular edema is intricate and multifactorial, in which the hyperglycemic state in diabetes induces a microangiopathy. Through several inflammatory and vasogenic mediators, including vascular endothelial growth factor (VEGF) upregulation and inflammatory cytokines and chemokines, pathologic changes are induced in the vascular endothelium triggering breakdown of the blood retinal barrier, causing extravasation of fluid into the extracellular space and manifesting clinically as macular edema, resulting in visual loss. The advent of medications targeting the VEGF pathway has led to great clinical improvements compared with the previous standard of care of laser therapy alone, as shown in studies such as RISE, RIDE, VIVID, VISTA, and DRCR. However, analyses have shown that many patients have inadequate response or are nonresponders to anti-VEGF therapy, demonstrating the need for additional therapies to more comprehensively treat this disease. Although corticosteroid treatments and implants have demonstrated some efficacy in adjunctive and supplemental treatment, the need to more adequately treat macular edema remains. Our knowledge of diabetic macular edema continues to grow, leading to new currently available and emerging pharmacotherapies to further enhance our treatment and restore vision in those affected by diabetic macular edema. This review will discuss the pathogenesis of diabetic macular edema and the pharmacologic therapies available for its treatment, including anti-VEGF, steroids, and newer therapies still in development, such as angiopoietin antagonists, Tie2 agonists, kallikrein inhibitors, interleukin inhibitors, and others.

A train of blue light pulses delivered through closed eyelids suppresses melatonin and phase shifts the human circadian system

Full Text Available Mariana G Figueiro, Andrew Bierman, Mark S ReaLighting Research Center, Rensselaer Polytechnic Institute, Troy, NY, USAAbstract: A model of circadian phototransduction was published in 2005 to predict the spectral sensitivity of the human circadian system to narrow-band and polychromatic light sources by combining responses to light from the spectral-opponent “blue” versus “yellow” cone bipolar pathway with direct responses to light by the intrinsically photosensitive retinal ganglion cells. In the model, depolarizing “blue” responses, but not hyperpolarizing “yellow” responses, from the “blue” versus “yellow” pathway are combined with the intrinsically photosensitive retinal ganglion cell responses. Intrinsically photosensitive retinal ganglion cell neurons are known to be much slower to respond to light than the cone pathway, so an implication of the model is that periodic flashes of “blue” light, but not “yellow” light, would be effective for stimulating the circadian system. A within-subjects study was designed to test the implications of the model regarding retinal exposures to brief flashes of light. The study was also aimed at broadening the foundation for clinical treatment of circadian sleep disorders by delivering flashing light through closed eyelids while people were asleep. In addition to a dark control night, the eyelids of 16 subjects were exposed to three light-stimulus conditions in the phase delay portion of the phase response curve while they were asleep: (1 2-second flashes of 111 W/m2 of blue (λmax ≈ 480 nm light once every minute for 1 hour, (2 131 W/m2 of green (λmax ≈ 527 nm light, continuously on for 1 hour, and (3 2-second flashes of the same green light once every minute for 1 hour. Inferential statistics showed that the blue flash light-stimulus condition significantly delayed circadian phase and significantly suppressed nocturnal melatonin.

Immersion pulmonary edema may occur during scuba diving, snorke-ling or swimming. It is a rare and often recurrent disease, mainly affecting individuals aged over 50 with high blood pressure. However it also occurs in young individuals with a healthy heart. The main symptoms are dyspnea, cough and hemoptysis. The outcome is often favorable under oxygen treatment but deaths are reported. A cardiac and pulmonary assessment is necessary to evaluate the risk of recurrence and possible contraindications to immersion.

Cerebral edema associated to scorpion sting: a two-case sting report

2005-12-01

Full Text Available Scorpionism is a public health problem in some places in Mexico. The clinical symptoms of envenomation by scorpion sting are by sympathetic and parasympathetic stimulation, developing systemic and local symptoms. The Central Nervous System (CNS is one of the organs that are affected. In some cases, cerebral edema develops. In this report we present two pediatric cases with the association of envenomation by scorpion sting and cerebral edema. The first case developed severe cerebral edema, which progressed to a fatal outcome; and the other case developed mild cerebral edema with a satisfactory evolution. The pathophysiology of this complication is not well known and probably is the consequence of hypoxia, secondary to respiratory failure, laryngospasm and seizures that are manifestations of envenomation by scorpion sting.

Cruz, Ana Sofia; Menezes, Sónia; Silva, Maria

2016-01-01

Pulmonary edema is caused by the accumulation of fluid within the air spaces and the interstitium of the lung. Neurogenic pulmonary edema is a clinical syndrome characterized by the acute onset of pulmonary edema following a significant central nervous system insult. It may be a less-recognized consequence of raised intracranial pressure due to obstructive hydrocephalus by blocked ventricular shunts. It usually appears within minutes to hours after the injury and has a high mortality rate if not recognized and treated appropriately. We report a patient with acute obstructive hydrocephalus due to ventriculo-atrial shunt dysfunction, proposed to urgent surgery for placement of external ventricular drainage, who presented with neurogenic pulmonary edema preoperatively. She was anesthetized and supportive treatment was instituted. At the end of the procedure the patient showed no clinical signs of respiratory distress, as prompt reduction in intracranial pressure facilitated the regression of the pulmonary edema. This report addresses the importance of recognition of neurogenic pulmonary edema as a possible perioperative complication resulting from an increase in intracranial pressure. If not recognized and treated appropriately, neurogenic pulmonary edema can lead to acute cardiopulmonary failure with global hypoperfusion and hypoxia. Therefore, awareness of and knowledge about the occurrence, clinical presentation and treatment are essential. Copyright © 2013 Sociedade Brasileira de Anestesiologia.

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.

Full Text Available Diversos fatores têm sido associados ao desenvolvimento de edema peritumoral nos meningiomas. Foram estudados os aspectos radiológicos e anátomo-patológicos de 51 meningiomas intracranianos operados no Hospital Universitário Clementino Fraga Filho (HUCFF. Dois terços dos meningiomas apresentavam edema perilesional. O tamanho dos meningiomas correlacionou-se com a presença de edema, sendo mais frequente nos meningiomas grandes (>4cm. A localização parece, também, influenciar no desenvolvimento do edema peritumoral, sendo mais acentuado nos meningiomas da asa do esfenóide e incomum nos meningiomas do tubérculo selar. Os subtipos histológicos de meningioma não se correlacionaram com a intensidade do edema peritumoral. Dos diversos mediadores químicos descritos na literatura recente relacionados ao desenvolvimento de edema peritumoral em tumores intracranianos, destaca-se o fator de crescimento do endotélio vascular (VEGF. A expressão nos meningiomas do VEGF e de seu receptor flk-1 foi estudada com técnica imuno-histoquímica, demonstrando a sua expressão nas células tumorais.

Full Text Available The aim of this study is to report a rare case of macular edema as a presentation of hydroxychloroquine-related retinal toxicity. We presented a case of a 46-year-old female patient using hydroxychloroquine for underlying rheumatoid arthritis (RA with blurred vision over the left eye. Uveitis and macular edema were found initially. Systemic survey did not reveal any other etiology. Topical corticosteroid was given under the impression of RA-related uveitis. The uveitis resolved 1 week later, but macular edema persisted in spite of treatment. Under the suspicion of drug-related complication, we try to discontinue hydroxychloroquine. Her symptoms improved gradually after cessation of hydroxychloroquine, and further serial image study confirmed subsiding of the macular edema without any further treatment. Except the well-known signs of the retinal toxicity, macular edema might be a rare presentation of hydroxychloroquine-related retinal toxicity.

The fractionated stereotactic radiotherapy by Cyberknife is an option in the treatment of eyes tumors. The advantages of the Cyberknife in the choroid melanomas are in its infra-millimetric precision, to the automated repositioning on the skull bones and to the conformity brought by the stereotaxy. The objective of this study was to validate the quality of repositioning and the immobility of the eyes with closed eyelids. Conclusion: the reproducibility of the eye positioning with closed eyelids seems enough to consider the conservative treatment of choroid melanomas by fractionated stereotactic radiotherapy by Cyberknife without implementation of fiducials nor retrobulbar anaesthesia.

The features of edema extending to the posterior limb of the internal capsule (PLIC) were investigated in a review of MR imaging (MRI), with the following results. Edema was seen along the lateral and medial margins of the PLIC, although the PLIC itself was resistant to edema. The edema along the lateral and medial margins tended to extend into the lentiform nucleus and thalamus, respectively, and was considered to be edema of the extrapyramidal and thalamocortical tracts. When edema was abundant, the PLIC was traversed by many edematous tracts which seemed to connect the lentiform nucleus with the thalamus. The PLIC looked like a comb, and this finding was a good anatomical landmark on MR T2-weighted images. We have used the term 'comb appearance' to describe this finding. (author)

Highlights: • We establish a new indicator of pericardial edema in developing zebrafish (precardiac edema). • Property of precardiac edema by TCDD is similar to that for conventional pericardial edema. • COX2b (but not COX2a)–thromboxane pathway is involved in precardiac edema by TCDD. - Abstract: The cardiovascular system is one of the most characteristic and important targets for developmental toxicity by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in fish larvae. However, knowledge of the mechanism of TCDD-induced edema after heterodimerization of aryl hydrocarbon receptor type 2 (AHR2) and AHR nuclear translocator type 1 (ARNT1) is still limited. In the present study, microscopic analysis with a high-speed camera revealed that TCDD increased the size of a small cavity between the heart and body wall in early eleutheroembryos, a toxic effect that we designate as precardiac edema. A concentration–response curve for precardiac edema at 2 days post fertilization (dpf) showed close similarity to that for conventional pericardial edema at 3 dpf. Precardiac edema caused by TCDD was reduced by morpholino knockdown of AHR2 and ARNT1, as well as by an antioxidant (ascorbic acid). A selective inhibitor of cyclooxygenase type 2 (COX2), NS398, also markedly inhibited TCDD-induced precardiac edema. A thromboxane receptor (TP) antagonist, ICI-192,605 almost abolished TCDD-induced precardiac edema and this effect was canceled by U46619, a TP agonist, which was not influential in the action of TCDD by itself. Knockdown of COX2b and thromboxane A synthase 1 (TBXS), but not COX2a, strongly reduced TCDD-induced precardiac edema. Knockdown of COX2b was without effect on mesencephalic circulation failure caused by TCDD. The edema by TCDD was also inhibited by knockdown of c-mpl, a thrombopoietin receptor necessary for thromobocyte production. Finally, induction of COX2b, but not COX2a, by TCDD was seen in eleutheroembryos at 3 dpf. These results suggest a role of the COX2b�

Bone marrow edema syndrome

Korompilias, Anastasios V.; Lykissas, Marios G.; Beris, Alexandros E.; Karantanas, Apostolos H.

2009-01-01

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 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.

A portable non-invasive head detecting system based on microwave technology was developed for evaluation of cerebral edema change inside human brain. Real-time monitoring of cerebral edema in the brain helps the clinician to assess medical condition and treatment. In this work, a microwave signal was transmitted and coupled into an open-end circular waveguide sensor, incident on a 3D printed head phantom, and reflected back to receiver. Theoretically, the operation of this instrument depends on the conductivity contrast between cerebral edema and healthy brain tissues. The efficacy of the proposed detecting system is verified using 3D printed anatomically and dielectrically realistic human head phantoms with simulated cerebral edema targets with different size. Changes in the amplitude of time domain result were shown to be induced by the expansion or decrease of the edema volume. The eventual goal of this proposed head evaluating system is use in the hospital as an effective real-time monitoring tool.

Dose calculation for permanent prostate implants incorporating spatially anisotropic linearly time-resolving edema

Purpose: The objectives of this study were (i) to develop a dose calculation method for permanent prostate implants that incorporates a clinically motivated model for edema and (ii) to illustrate the use of the method by calculating the preimplant dosimetry error for a reference configuration of 125 I, 103 Pd, and 137 Cs seeds subject to edema-induced motions corresponding to a variety of model parameters. Methods: A model for spatially anisotropic edema that resolves linearly with time was developed based on serial magnetic resonance imaging measurements made previously at our center to characterize the edema for a group of n=40 prostate implant patients [R. S. Sloboda et al., ''Time course of prostatic edema post permanent seed implant determined by magnetic resonance imaging,'' Brachytherapy 9, 354-361 (2010)]. Model parameters consisted of edema magnitude, Δ, and period, T. The TG-43 dose calculation formalism for a point source was extended to incorporate the edema model, thus enabling calculation via numerical integration of the cumulative dose around an individual seed in the presence of edema. Using an even power piecewise-continuous polynomial representation for the radial dose function, the cumulative dose was also expressed in closed analytical form. Application of the method was illustrated by calculating the preimplant dosimetry error, RE preplan , in a 5x5x5 cm 3 volume for 125 I (Oncura 6711), 103 Pd (Theragenics 200), and 131 Cs (IsoRay CS-1) seeds arranged in the Radiological Physics Center test case 2 configuration for a range of edema relative magnitudes (Δ=[0.1,0.2,0.4,0.6,1.0]) and periods (T=[28,56,84] d). Results were compared to preimplant dosimetry errors calculated using a variation of the isotropic edema model developed by Chen et al. [''Dosimetric effects of edema in permanent prostate seed implants: A rigorous solution,'' Int. J. Radiat. Oncol., Biol., Phys. 47, 1405-1419 (2000)]. Results: As expected, RE preplan for our edema model

Edema surrounding the medial collateral ligament (MCL) is seen on MR imaging in patients with MCL injuries and in patients with radiographic osteoarthritis in the non-traumatic knee. Because we noted MCL edema in patients without prior trauma or osteoarthritis, we studied the association between intra-articular pathology and MCL edema in patients without knee trauma. We evaluated the MR examinations of 247 consecutive patients (121 male, 126 female with a mean age of 44 years) without recent trauma for the presence of edema surrounding the MCL, meniscal and ACL tears, medial meniscal extrusion, medial compartment chondromalacia, and osteoarthritis. The percentages of patients illustrating MCL edema with and without each type of pathology were compared using Fisher's exact test to determine if there was a statistically significant association. We found MCL edema in 60% of 247 patients. MCL edema was present in 67% of patients with medial meniscal tears, 35% with lateral meniscal tears, 100% with meniscal extrusion of 3 mm or more, 78% with femoral chondromalacia, 82% with tibial chondromalacia, and 50% with osteoarthritis. The percentage of patients with edema increased with the severity of the chondromalacia. These associations were all statistically significant (p <0.02). The mean age of those with MCL edema was 49.7 years compared with 34.9 years without MCL edema (p <0.001). Patient gender and ACL tear did not correlate with MCL edema. Nine (4%) of the 247 patients had MCL edema without intra-articular pathology. None of these 9 patients had MCL tenderness or joint laxity on physical examination. We confirmed that MCL edema is associated with osteoarthritis, but is also associated with meniscal tears, meniscal extrusion, and chondromalacia. In addition, MCL edema can be seen in patients without intra-articular pathology, recent trauma or MCL abnormality on physical examination. (orig.)

Full Text Available OBJECTIVE: Determine the prevalence of postural edema and investigate whether working posture - sitting down or standing up - affect its frequency. METHODS: Sixteen traffic control agents were assessed by water displacement volumetry and the results were analyzed in two groups, depending on working posture. Those who worked standing up for more than 4 hours were allocated to the SU group and those who worked sitting down for more than 4 hours were allocated to the SD group. Each worker was assessed before and after their working shift for three consecutive days. Data were analyzed using ANOVA and the test of equality of two proportions. The significance level was set at p ≤ 0.05. The assessment showed that members of both groups had postural edema of the lower extremities (p ≤ 0.001. RESULTS: When the frequency of postural edema was compared across groups, a trend was observed for greater edema formation in the SU group than in the SD group, although without statistically significant difference. CONCLUSION: It was concluded that traffic control agents suffer postural edema after 4 hours working in either of the postures investigated although with a predominance of edema formation among those who work standing up.

Effect of edema, relative biological effectiveness, and dose heterogeneity on prostate brachytherapy

Many factors influence response in low-dose-rate (LDR) brachytherapy of prostate cancer. Among them, edema, relative biological effectiveness (RBE), and dose heterogeneity have not been fully modeled previously. In this work, the generalized linear-quadratic (LQ) model, extended to account for the effects of edema, RBE, and dose heterogeneity, was used to assess these factors and their combination effect. Published clinical data have shown that prostate edema after seed implant has a magnitude (ratio of post- to preimplant volume) of 1.3-2.0 and resolves exponentially with a half-life of 4-25 days over the duration of the implant dose delivery. Based on these parameters and a representative dose-volume histogram (DVH), we investigated the influence of edema on the implant dose distribution. The LQ parameters (α=0.15 Gy -1 and α/β=3.1 Gy) determined in earlier studies were used to calculate the equivalent uniform dose in 2 Gy fractions (EUD 2 ) with respect to three effects: edema, RBE, and dose heterogeneity for 125 I and 103 Pd implants. The EUD 2 analysis shows a negative effect of edema and dose heterogeneity on tumor cell killing because the prostate edema degrades the dose coverage to tumor target. For the representative DVH, the V 100 (volume covered by 100% of prescription dose) decreases from 93% to 91% and 86%, and the D 90 (dose covering 90% of target volume) decrease from 107% to 102% and 94% of prescription dose for 125 I and 103 Pd implants, respectively. Conversely, the RBE effect of LDR brachytherapy [versus external-beam radiotherapy (EBRT) and high-dose-rate (HDR) brachytherapy] enhances dose effect on tumor cell kill. In order to balance the negative effects of edema and dose heterogeneity, the RBE of prostate brachytherapy was determined to be approximately 1.2-1.4 for 125 I and 1.3-1.6 for 103 Pd implants. These RBE values are consistent with the RBE data published in the literature. These results may explain why in earlier modeling studies

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.

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. 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. 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 < 0.001, Spearman-Rho) and depth of tumor (p < 0.001). In a multifactorial analysis of maximum edema with the uncorrelated factors age, regional location of tumor and degree of necrosis, only the extent of necrosis (p = 0.022) had a significant effect. Age at diagnosis does not determine degree of peritumoral edema, and tumor localization in the white matter is associated with greater

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.

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 Remitting seronegative symmetrical synovitis with pitting edema is a rare rheumatological disorder that presents with symmetrical hand and/or foot edema resembling rheumatoid arthritis. It is generally seen in male patients in older age, but atypical cases in different age groups have been documented. Although no clear mechanism has been described, certain genetic and environmental factors have been suggested for etiopathogenesis. Medical treatment is mainly focused on glucocorticoid therapy. This article aims to discuss the Remitting seronegative symmetrical synovitis with pitting edema syndrome and to review the current literature. [Cukurova Med J 2017; 42(1.000: 147-154

Solid facial edema (SFE) is a rare complication of acne vulgaris. To examine the clinical features of acne patients with solid facial edema, and to give an overview on the outcome of previous topical and systemic treatments in the cases so far published. We report two cases from Switzerland, both young men with initially papulopustular acne resistant to topical retinoids. Both cases responded to oral isotretinoin, in one case combined with oral steroids. Our cases show a strikingly similar clinical appearance to the cases described by Connelly and Winkelmann in 1985 (Connelly MG, Winkelmann RK. Solid facial edema as a complication of acne vulgaris. Arch Dermatol. 1985;121(1):87), as well as to cases of Morbihan's disease that occurs as a rare complication of rosacea. Even 30 years after, the cause of the edema remains unknown. In two of the original four cases, a potential triggering factor was identified such as facial trauma or insect bites; however, our two patients did not report such occurrencies. The rare cases of solid facial edema in both acne and rosacea might hold the key to understanding the specific inflammatory pattern that creates both persisting inflammation and disturbed fluid homeostasis which can occur as a slightly different presentation in dermatomyositis, angioedema, Heerfordt's syndrome and other conditions.

Massive Scrotal Edema: An Unusual Manifestation of Obstructive Sleep Apnea and Obesity-Hypoventilation Syndrome

Full Text Available Obstructive sleep apnea (OSA may occur in association with obesity-hypoventilation (Pickwickian syndrome, a disorder of ventilatory control affecting individuals with morbid obesity. Through the pressor effects of chronic hypercapnia and hypoxemia, this syndrome may result in pulmonary hypertension, right heart failure, and massive peripheral edema. We present a case of severe scrotal edema in a 36-year-old male with OSA and obesity-hypoventilation syndrome. A tracheostomy was performed to relieve hypoxemia and led to dramatic improvement of scrotal edema. No scrotal surgery was necessary. Followup at two months showed complete resolution of scrotal edema, improvement in mental status, and normalization of arterial blood gas measurements. This case demonstrates that OSA and obesity-hypoventilation syndrome may present with massive scrotal edema. Furthermore, if OSA is recognized as the cause of right heart failure, and if the apnea is corrected, the resultant improvement in cardiac function may allow reversal of massive peripheral, including scrotal, edema.

Ontogeny of metabolic rate and red blood cell size in eyelid geckos: species follow different paths.

Directory of Open Access Journals (Sweden)

Zuzana Starostová

Full Text Available While metabolism is a fundamental feature of all organisms, the causes of its scaling with body mass are not yet fully explained. Nevertheless, observations of negative correlations between red blood cell (RBC size and the rate of metabolism suggest that size variation of these cells responsible for oxygen supply may play a crucial role in determining metabolic rate scaling in vertebrates. Based on a prediction derived from the Cell Metabolism Hypothesis, metabolic rate should increase linearly with body mass in species with RBC size invariance, and slower than linearly when RBC size increases with body mass. We found support for that prediction in five species of eyelid geckos (family Eublepharidae with different patterns of RBC size variation during ontogenetic growth. During ontogeny, metabolic rate increases nearly linearly with body mass in those species of eyelid geckos where there is no correlation between RBC size and body mass, whereas non-linearity of metabolic rate scaling is evident in those species with ontogenetic increase of RBC size. Our findings provide evidence that ontogenetic variability in RBC size, possibly correlating with sizes of other cell types, could have important physiological consequences and can contribute to qualitatively different shape of the intraspecific relationship between metabolic rate and body mass.

Current autopsy principles for evaluating the existence of brain edema are based on a macroscopic subjective assessment performed by pathologists. The gold standard is a time-consuming histological verification of the presence of the edema. By measuring the diameters of the cranial cavity, as individually determined morphometric parameters, a mathematical model for rapid evaluation of brain edema was created, based on the brain weight measured during the autopsy. A cohort study was performed on 110 subjects, divided into two groups according to the histological presence or absence of (the - deleted from the text) brain edema. In all subjects, the following measures were determined: the volume and the diameters of the cranial cavity (longitudinal and transverse distance and height), the brain volume, and the brain weight. The complex mathematical algorithm revealed a formula for the coefficient ε, which is useful to conclude whether a brain edema is present or not. The average density of non-edematous brain is 0.967 g/ml, while the average density of edematous brain is 1.148 g/ml. The resulting formula for the coefficient ε is (5.79 x longitudinal distance x transverse distance)/brain weight. Coefficient ε can be calculated using measurements of the diameters of the cranial cavity and the brain weight, performed during the autopsy. If the resulting ε is less than 0.9484, it could be stated that there is cerebral edema with a reliability of 98.5%. The method discussed in this paper aims to eliminate the burden of relying on subjective assessments when determining the presence of a brain edema.

Microscopic study of edema in hydatidiform mole

Directory of Open Access Journals (Sweden)

Olivar C. Castejón

2014-09-01

Full Text Available Objectives: the purpose of this study is to use light microscopy and scanning electron microscopy to determine the effect of edema on the structure of the molar vesicle. Methods: samples were taken from the complete hydatidiform mole and processed using conventional light and scanning electron microscopy techniques and an observation protocol that identified four variables: factors underlying the development of edema; the condition of the trophoblast basement membrane, development of the villi, accumulation and degeneration of sulphated mucosubstances at stromal level. Results: light microscopy showed a permeable trophoblastic basement membrane, a swollen syncytium, edematous regions disorganizating the stromal region and causing ischemic necrosis of cells. Using scanning electron microscopy, the basement membrane was found to be distended and thickened, with large irregular holes for the entry and movement of liquid, leaving a wide range of fluids during the influx process and depriving stromal cells of nutrition. Conclusions: a new three-dimensional view of the changes brought about by the entry of fluids into the stroma of molar hydropic vesicles was provided by scanning electron microscopy and confirmed by light microscopy, thereby explaining the changes occurring at the level of the stroma as an effect of the edema.

Reexpansion pulmonary edema: review of pediatric cases.

Science.gov (United States)

Kira, Shinichiro

2014-03-01

Reexpansion pulmonary edema (RPE) is an increased permeability pulmonary edema that usually occurs in the reexpanded lung after several days of lung collapse. This condition is recognized to occur more frequently in patients under the age of 40 years, but there has been no detailed analysis of reported pediatric cases of RPE to date. For this review, PubMed literature searches were performed using the following terms: 're(-)expansion pulmonary (o)edema' AND ('child' OR 'children' OR 'infant' OR 'boy' OR 'girl' OR 'adolescent'). The 22 pediatric cases of RPE identified were included in this review. RPE was reported in almost the entire pediatric age range, and as in adult cases, the severity ranged from subclinical to lethal. No specific treatment for RPE was identified, and treatment was administered according to the clinical features of each patient. Of the 22 reported cases, 10 occurred during the perioperative period, but were not related to any specific surgical procedures or anesthetic techniques, or to the duration of lung collapse. Pediatric anesthesiologists should be aware that pediatric RPE can occur after reexpansion of any collapsed lung and that some invasive therapies can be useful in severe cases. © 2013 John Wiley & Sons Ltd.

The extracts obtained from 14 plants of the Mexican medicinal flora were assessed for anti-inflammatory activity by carrageenan-induced rat paw edema model. The i.p. administration of the extracts at a dose of 400 mg/kg produced a high reduction of edema with 70% of the plant extracts. Oenothera rosea methanol extract, Sphaeralcea angustifolia chloroform extract, Acaciafarnesiana, Larrea tridentata and Rubus coriifolius methanol extracts as well as the aqueous extract of Chamaedora tepejilote were demonstrated to be particularly active against the induced hind-paw edema. Moderate inhibition of edema formation was also demonstrated with the methanol extracts of Astianthus viminalis, Brickellia paniculata, C. tepejilote and Justicia spicigera.

Background and objectives Although venous congestion has been linked to renal dysfunction in heart failure, its significance in a broader context has not been investigated. Design, setting, participants, & measurements Using an inception cohort of 12,778 critically ill adult patients admitted to an urban tertiary medical center between 2001 and 2008, we examined whether the presence of peripheral edema on admission physical examination was associated with an increased risk of AKI within the first 7 days of critical illness. In addition, in those with admission central venous pressure (CVP) measurements, we examined the association of CVPs with subsequent AKI. AKI was defined using the Kidney Disease Improving Global Outcomes criteria. Results Of the 18% (n=2338) of patients with peripheral edema on admission, 27% (n=631) developed AKI, compared with 16% (n=1713) of those without peripheral edema. In a model that included adjustment for comorbidities, severity of illness, and the presence of pulmonary edema, peripheral edema was associated with a 30% higher risk of AKI (95% confidence interval [95% CI], 1.15 to 1.46; Pedema was not significantly related to risk. Peripheral edema was also associated with a 13% higher adjusted risk of a higher AKI stage (95% CI, 1.07 to 1.20; Pedema were associated with 34% (95% CI, 1.10 to 1.65), 17% (95% CI, 0.96 to 1.14), 47% (95% CI, 1.18 to 1.83), and 57% (95% CI, 1.07 to 2.31) higher adjusted risk of AKI, respectively, compared with edema-free patients. In the 4761 patients with admission CVP measurements, each 1 cm H2O higher CVP was associated with a 2% higher adjusted risk of AKI (95% CI, 1.00 to 1.03; P=0.02). Conclusions Venous congestion, as manifested as either peripheral edema or increased CVP, is directly associated with AKI in critically ill patients. Whether treatment of venous congestion with diuretics can modify this risk will require further study. PMID:26787777

Magnetic resonance perfusion and diffusion studies were undertaken to clarify the significance of ischemia in the pathogenesis of peritumoral brain edema in patients with meningiomas. Included in this study were 26 patients with 27 meningiomas and 5 gliomas. Perfusion-weighted imaging (PWI) was performed using a gradient-echo, echo-planar-imaging (EPI) sequence for calculation of the relative regional cerebral blood volume (rrCBV) and the relative regional cerebral blood flow index (rrCBFi). Furthermore, multi-slice spin-echo EPI sequences were applied in order to obtain anisotropic and isotropic diffusion-weighted imaging (DWI). Apparent diffusion coefficient (ADC) values were then calculated for peritumoral brain parenchyma from tumors, with and without edema, using various diffusion sensitivities. Meningiomas without edema demonstrated a minimal increase of perfusion parameters in the peritumoral brain tissue. In contrast, cases with brain edema had highly significant (p 2 . The DWI showed a significantly larger ADC value within areas of brain edema, compared with the normal white matter (0.74 x 10 -3 vs 1.55 x 10 -3 mm 2 /s; p<0.0001). Increases in EI correlated with increases in ADC values. In 31% of the meningiomas associated with edema, areas with increased signal, probable ischemia, demonstrated significantly lower ADC values, in comparison with the rest of the edematous areas. These areas were confined to tissue immediately adjacent to the tumor. In general, the decrease in rrCBV in brain edema represents a consequence from, rather than a cause of, vasogenic edema. Ischemic alterations can be regarded as secondary, facultative phenomena in the pathogenesis of meningioma-related brain edema. (orig.)

2005-07-01

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.

The eyelid geckos (family Eublepharidae) include both species with temperature-dependent sex determination and species where genotypic sex determination (GSD) was suggested based on the observation of equal sex ratios at several incubation temperatures. In this study, we present data on karyotypes and chromosomal characteristics in 12 species (Aeluroscalabotes felinus, Coleonyx brevis, Coleonyx elegans, Coleonyx variegatus, Eublepharis angramainyu, Eublepharis macularius, Goniurosaurus araneus, Goniurosaurus lichtenfelderi, Goniurosaurus luii, Goniurosaurus splendens, Hemitheconyx caudicinctus, and Holodactylus africanus) covering all genera of the family, and search for the presence of heteromorphic sex chromosomes. Phylogenetic mapping of chromosomal changes showed a long evolutionary stasis of karyotypes with all acrocentric chromosomes followed by numerous chromosomal rearrangements in the ancestors of two lineages. We have found heteromorphic sex chromosomes in only one species, which suggests that sex chromosomes in most GSD species of the eyelid geckos are not morphologically differentiated. The sexual difference in karyotype was detected only in C. elegans which has a multiple sex chromosome system (X(1)X(2)Y). The metacentric Y chromosome evolved most likely via centric fusion of two acrocentric chromosomes involving loss of interstitial telomeric sequences. We conclude that the eyelid geckos exhibit diversity in sex determination ranging from the absence of any sexual differences to heteromorphic sex chromosomes, which makes them an interesting system for exploring the evolutionary origin of sexually dimorphic genomes.

Objective: To evaluation the treatment response of Gamma Knife surgery (GKS) for the control of cerebral metastases and peritumoral edema using standard MRI. Method: 42 consecutive patients with 75 metastatic lesions were recruited in this study (28 men, 14 women; mean age 60±12 years). Gadolinium enhancement T 1 WI scans were performed on one day before and three months after GKS. Treatment response was evaluated by calculating the changes of tumor volume and edema index before and after GKS. Results: Mean tumor volumes on the baseline and post treatment were 7.0 cm 3 and 3.3 cm 3 respectively. Mean peritumoral edema indexes were 9.9 and 4.3 respectively. Tumor growth control rate and peritumoral edema control rate were 91% and 85% respectively. Conclusion: GKS is effective for both brain metastasis and peritumoral edema, and the tumor volume influences GKS efficacy. Conventional MRI provides useful information to predict treatment response of GKS for cerebral metastasis. (authors)

Surgical resection in combination with radiotherapy in selected cases remains the best option for patients with cerebral metastases. Postoperative relapse of brain metastases occurs frequently and can be reduced by postoperative whole-brain radiotherapy (WBRT). Continuous spread of tumor cells from the primary lesions is debated as a cause of recurrence. It is well known that in gliomas, infiltration takes place within the surrounding edema. Obviously, most brain metastases are usually associated with peritumoral edema, which may act as an indicator of infiltration and more aggressive tumor biology. Therefore, we aimed to investigate the correlation of tumor and edema volumes with overall survival in patients with cerebral metastases. A total of 143 patients diagnosed with brain metastasis (male:female=1.1:1) who underwent surgical resection were included retrospectively in this analysis. Clinical data were retrieved from electronic patient files. The volumes of tumor and edema calculated by manual delineation. The ratio of edema to tumor volume was calculated, leading to dichotomization of the patients. The median tumor volume was 20.1 cc (range=0.8-90.8 cc) and the median volume of edema 49.5 cc (range=0-179.9 cc). The volume of metastases did not significantly correlate with overall survival. The ratio of edema to tumor volume was also not a prognostic factor in terms of overall survival. Only surgical resection, preoperative recursive partitioning analysis class, and postoperative addition of WBRT, as well as female sex, demonstrated beneficial effects. The extent of edema surrounding cerebral metastases does not appear to influence overall survival in patients suffering from brain metastases, although it seems to be responsible for most of the patients' symptoms. The hypothesis that the extent of edema was disadvantageous concerning survival was supported by our data. Copyright© 2017, International Institute of Anticancer Research (Dr. George J. Delinasios

Methods and Materials: Forty-eight primary GBM patients received three-dimensional conformal radiotherapy that did not intentionally include peritumoral edema within the clinical target volume between July 2000 and June 2001. All 48 patients have subsequently recurred, and their original treatment planning parameters were used for this study. New theoretical radiation treatment plans were created for the same 48 patients, based on Radiation Therapy Oncology Group (RTOG) target delineation guidelines that specify inclusion of peritumoral edema. Target volume and recurrent tumor coverage, as well as percent volume of normal brain irradiated, were assessed for both methods of target delineation using dose-volume histograms. Results: A comparison between the location of recurrent tumor and peritumoral edema volumes from all 48 cases failed to show correlation by linear regression modeling (r 2 0.0007; p = 0.3). For patients with edema >75 cm 3 , the percent volume of brain irradiated to 46 Gy was significantly greater in treatment plans that intentionally included peritumoral edema compared with those that did not (38% vs. 31%; p = 0.003). The pattern of failure was identical between the two sets of plans (40 central, 3 in-field, 3 marginal, and 2 distant recurrence). Conclusion: Clinical target volume delineation based on a 2-cm margin rather than on peritumoral edema did not seem to alter the central pattern of failure for patients with GBM. For patients with peritumoral edema >75 cm 3 , using a constant 2-cm margin resulted in a smaller median percent volume of brain being irradiated to 30 Gy, 46 Gy, and 50 Gy compared with corresponding theoretical RTOG plans that deliberately included peritumoral edema

Full Text Available Mariana G Figueiro, Barbara Plitnick, Mark S Rea Lighting Research Center, Rensselaer Polytechnic Institute, Troy, NY, USA Abstract: Circadian rhythm disturbances parallel the increased prevalence of sleep disorders in older adults. Light therapies that specifically target regulation of the circadian system in principle could be used to treat sleep disorders in this population. Current recommendations for light treatment require the patients to sit in front of a bright light box for at least 1 hour daily, perhaps limiting their willingness to comply. Light applied through closed eyelids during sleep might not only be efficacious for changing circadian phase but also lead to better compliance because patients would receive light treatment while sleeping. Reported here are the results of two studies investigating the impact of a train of 480 nm (blue light pulses presented to the retina through closed eyelids on melatonin suppression (laboratory study and on delaying circadian phase (field study. Both studies employed a sleep mask that provided narrowband blue light pulses of 2-second duration every 30 seconds from arrays of light-emitting diodes. The results of the laboratory study demonstrated that the blue light pulses significantly suppressed melatonin by an amount similar to that previously shown in the same protocol at half the frequency (ie, one 2-second pulse every minute for 1 hour. The results of the field study demonstrated that blue light pulses given early in the sleep episode significantly delayed circadian phase in older adults; these results are the first to demonstrate the efficacy and practicality of light treatment by a sleep mask aimed at adjusting circadian phase in a home setting.

Full Text Available We describe a patient with Kawasaki disease (KD and retropharyngeal edema following a blackfly bite. An 8-year-old boy was referred to our hospital because of a 3-day-history of fever and left neck swelling and redness after a blackfly bite. Computed tomography of the neck revealed left cervical lymph nodes swelling with edema, increased density of the adjacent subcutaneous tissue layer, and low density of the retropharyngeum. The patient was initially presumed to have cervical cellulitis, lymphadenitis, and retropharyngeal abscess. He was administered antibiotics intravenously, which did not improve his condition. The patient subsequently exhibited other signs of KD and was diagnosed with KD and retropharyngeal edema. Intravenous immunoglobulin therapy and oral flurbiprofen completely resolved the symptoms and signs. A blackfly bite sometimes incites a systemic reaction in humans due to a hypersensitive reaction to salivary secretions, which may have contributed to the development of KD in our patient.

To explore the reasonable therapeutic strategy for different types of epicanthus. Patients with epicanthus were classificated according to the shape, extent and inner canthal distance and treated with different methods appropriately. Modified asymmetric Z plasty with two curve method was used in lower eyelid type epicanthus, inner canthus type epicanthus and severe upper eyelid type epicanthus. Moderate upper epicanthus underwent '-' shape method. Mild Upper epicanthus in two conditions which underwent nasal augumentation and double eyelid formation with normal inner canthal distance need no correction surgery. The other mild epicanthus underwent '-' shape method. A total of 66 cases underwent the classification and the appropriate treatment. All wounds healed well. During 3 to 12 months follow-up period, all epicanthus were corrected completely with natural contour and unconspicuous scars. All patients were satisfied with the results. Classification of epicanthus hosed on the shape, extent and inner canthal distance and correction with appropriate methods is a reasonable therapeutic strategy.

Full Text Available Molluscum contagiosum (MC is a viral infection of the skin and mucosal tissues characterized by skin-colored or transparent round nodules with a dimple or pit in the center. The infection is caused by a DNA poxvirus called the MC virus. Although MC generally occurs in children, it has also been reported in immunocompromised and atopic patients. The virus is transmitted by skin contact or sexual intercourse. The lesions disappear spontaneously within several months in most cases. However, excision, cryotherapy, cauterization, topical chemical and antiviral agents, and/or oral cimetidine are used in refractory cases or to accelerate the healing process. Herein, we discussed the clinical findings and our treatment of two patients with unilateral chronic conjunctivitis associated with eyelid MC lesions in light of the literature.

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.

Acute bone marrow edema of the hip: role of MR imaging

2007-01-01

Acute bone marrow edema of the hip is a diagnostic challenge for both radiologists and clinicians. Marrow edema is often seen in patients with hip pain and restriction of motion. In patients with acute non-traumatic hip pain, whose radiographs are negative or inconclusive, MR imaging is the imaging study of choice. MR imaging is the most sensitive and specific imaging technique for detecting transient osteoporosis and osteonecrosis, as well as for detecting and staging fractures and microfractures. MR imaging is able to show marrow involvement in various inflammatory disorders and to diagnose reactive marrow edema from femoroacetabular impingment and greater trochanteric pain syndrome. In patients with septic arthritis, it may also depict associated marrow edema and suggest its reactive or infectious origin. For the neoplastic disorders, although plain radiographs should be the initial examination, MR imaging may follow for assessing extension to the surrounding soft tissues and/or associated pathologic fracture, facilitating thus the treatment planning. Computed tomography is more accurate compared with MR imaging in diagnosing intra-articular osteoid osteomas. (orig.)

We reviewed the MR appearances of six cases of longitudinal stress fracture of the lower extremity.Results. One fracture was in the femur and five were in the tibia. Four of the tibial fractures showed edema starting in the mid-tibia at the level of the nutrient foramen with the fracture on the anteromedial cortex. The other tibial fracture started at the nutrient foramen. Three fractures (two tibial and the femur fracture) showed eccentric marrow edema; all fractures showed either eccentric periosteal reaction or soft tissue edema.Conclusion. Primary diagnosis of longitudinal stress fracture is made by finding a vertical cleft on one or more axial images. Secondary signs of position of the nutrient foramen and patterns of edema may be useful. (orig.)

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.

Full Text Available AIM:To evaluate the efficacy and safety of methazolamide in treating refractory uveitic macular edema. METHODS: Retrospective self-controlled study was designed. A total of 15 patients(20 eyeswith refractory uveitic macular edema which used methazolamide as adjuvant therapy were enrolled in Shanghai First People's Hospital from January 2015 to June 2016. The changes of central macular thickness(CMTand best corrected visual acuity(BCVAwere observed at baseline and 2, 4, 8wk after treatment. We also focused on the incidence of complications and relapse. RESULTS: The CMT was 445.95±154.10μm, 338.83±138.34μm, 251.50±40.20μm, 244.90±35.68μm at baseline, 2, 4 and 8wk after treatment, respectively. The differences among them were statistically significant(F=15.467, PF=5.208, PCONCLUSION: Methazolamide is beneficial in improving macular edema and vision in 4wk. When the cumulative dose is more than 1400mg, we need pay attention to the complications. After discontinuing methazolamide for 1wk, macular edema relapsed in some patients, and more than half of patients recurred after 3mo. So the patients should be followed closely in 3mo after withdrawal of methazolamide.

This study reviewed the dental literature in order to determine the association of bone marrow edema with osteoarthritis and temporomandibular joint (TMJ) internal derangement disorders. A literature search was performed using electronic databases PubMed/Medline (National Library of Medicine, Bethesda, Maryland) and Cochrane for articles published during the last 15 years (January 2000-December 2014). A predetermined inclusion and exclusion criteria were used for filtering the scientific papers. Research articles fulfilling the basic inclusion criteria were included in the review. The reviewed studies showed that bone marrow edema is found in painful joints with osteoarthritis in a majority of cases. A few cases with no pain or significant degenerative changes are reported to have a bone marrow edema pattern as well. Bone marrow edema, increased fluid level, and pain are associated with osteoarthritis in the majority of patients reporting TMJ arthritis. Degenerative and disc displacement conditions are multifactorial and require further investigations. Magnetic resonance imaging can be employed to detect bone marrow edema even in the absence of pain and clinical symptoms in the patients of internal derangements.

The regional clearance of /sup 99m/Tc-diethylenetriamine penta-acetate from the lungs was measured in 14 patients with noncardiogenic pulmonary edema, six patients with acute pulmonary edema secondary to heart failure, and 29 normal subjects. The radionuclide was delivered in an aerosol which was inhaled for 120 seconds, and the subsequent decline of radioactivity from the lungs was monitored for seven minutes over each of six peripheral regions of interest with a computerized scintillation camera. The average /sup 99m/Tc-DTPA clearance of these regions was accelerated above the 98 percent confidence limits in all but three of the patients with noncardiogenic edema. The mean clearance value in this group of patients was significantly greater than those in normal subjects or patients with cardiogenic pulmonary edema. Clearances returned toward normal in each of seven subjects who improved clinically. Only one of the patients with cardiogenic pulmonary edema had an elevated average clearance rate, and the mean clearance for this population was not statistically greater than normal. This procedure appears to detect increased epithelial permeability caused by lung injury and may help distinguish between cardiogenic and noncardiogenic pulmonary edema

Traumatic brain injury (TBI) is associated with poor neurological outcome, including necrosis and brain edema. In this study, we investigated whether agmatine treatment reduces edema and apoptotic cell death after TBI. TBI was produced by cold injury to the cerebral primary motor cortex of rats. Agmatine was administered 30 min after injury and once daily until the end of the experiment. Animals were sacrificed for analysis at 1, 2, or 7 days after the injury. Various neurological analyses were performed to investigate disruption of the blood-brain barrier (BBB) and neurological dysfunction after TBI. To examine the extent of brain edema after TBI, the expression of aquaporins (AQPs), phosphorylation of mitogen-activated protein kinases (MAPKs), and nuclear translocation of nuclear factor-κB (NF-κB) were investigated. Our findings demonstrated that agmatine treatment significantly reduces brain edema after TBI by suppressing the expression of AQP1, 4, and 9. In addition, agmatine treatment significantly reduced apoptotic cell death by suppressing the phosphorylation of MAPKs and by increasing the nuclear translocation of NF-κB after TBI. These results suggest that agmatine treatment may have therapeutic potential for brain edema and neural cell death in various central nervous system diseases.

Diabetic macular edema (DME), one the most prevalent causes of visual loss in industrialized countries, may be diagnosed at any stage of diabetic retinopathy. The diagnosis, treatment, and follow up of DME have become straightforward with recent developments in fundus imaging, such as optical coherence tomography. Laser photocoagulation, intravitreal injections, and pars plana vitrectomy surgery are the current treatment modalities; however, the positive effects of currently available intravitreally injected agents are temporary. At this point, further treatment choices are needed for a permanent effect. The articles published between 1985-2015 years on major databases were searched and most appropriate 40 papers were used to write this review article.

2008-01-01

The robustness of treatment planning to prostatic edema for three different isotopes ( 125 I, 103 Pd, and 131 Cs) is explored using dynamical dose calculations on 25 different clinical prostate cases. The treatment plans were made using the inverse planning by simulated annealing (IPSA) algorithm. The prescription was 144, 127, and 125 Gy for 125 I, 131 Cs, and 103 Pd, respectively. For each isotope, three dose distribution schemes were used to impose different protection levels to the urethra: V 120 =0%, V 150 =0%, and V 150 =30%. Eleven initial edema values were considered ranging from 1.0 (no edema) to 2.0 (100%). The edema was assumed to resolve exponentially with time. The prostate volume, seed positions, and seed activity were dynamically tracked to produce the final dose distribution. Edema decay half-lives of 10, 30, and 50 days were used. A total of 675 dynamical calculations were performed for each initial edema value. For the 125 I isotope, limiting the urethra V 120 to 0% leads to a prostate D 90 under 140 Gy for initial edema values above 1.5. Planning with urethra V 150 at 0% provides a good response to the edema; the prostate D 90 remains higher than 140 Gy for edema values up to 1.8 and a half-life of 30 days or less. For 103 Pd, the prostate D 90 is under 97% of the prescription dose for approximately 66%, 40%, and 30% of edema values for urethra V 120 =0%, V 150 =0%, and V 150 =30%, respectively. Similar behavior is seen for 131 Cs and the center of the prostate becomes 'cold' for almost all edema scenarios. The magnitude of the edema following prostate brachytherapy, as well as the half-life of the isotope used and that of the edema resorption, all have important impacts on the dose distribution. The 125 I isotope with its longer half-life is more robust to prostatic edema. Setting up good planning objectives can provide an adequate compromise between organ doses and robustness. This is even more important since seed misplacements will contribute

To analyze high risk factors of postoperative upper gastrointestinal (GI) bleeding after neurosurgery so as to give guidance for prevention of GI bleeding. A questionnaire was developed to investigate the medical records of 1500 patients who were hospitalized and underwent neurosurgical operations in 1997. Logistic regression analysis was made. 1430 valid questionnaires were obtained. Postoperative upper GI bleeding occurred in 75 patients (5.24%). The incidence of upper GI bleeding were 6.64% (54/813) in the male patients and 3.40% (21/617) in the female persons (P = 0.007); 9.88% (41/415) in those aged > 50 and 3.35% in those aged hematoma, intraventricular hemorrhage, subdural hematoma, and extradural hematoma were 15.7%, 10.0%, 6.00%, and 2.94% respectively (P = 0.02). The incidence of upper GI bleeding of the patients with tumors of fourth ventricle of cerebrum, brainstem, cerebral hemisphere, and sellar hypothalamus were 15.79% (3/19), 7.89%, 5.71%, and 3.74% respectively. In the emergent cases, the incidence of upper GI bleeding was higher in those with hypertension. The incidence of upper GI bleeding was 5.46% in the patients undergoing adrenocortical hormone treatment, significantly higher than that in those who did not receive such treatment (2.13%). Patients who are at high risk of developing postoperative upper GI bleeding including that: age greater than 50 years; male; Glasgow Coma Score less than 10 pre and post operation; The lesion was located in brain stem and forth ventricle; Hypertensive cerebral hemorrhage; Intracerebral and intraventricular hemorrhagic brain trauma; Postoperative pneumonia, brain edema, encephalic high pressure, pyogenic infection of the central nervous system and other postoperative complications. The mortality of patients with postoperative upper GI bleeding was evidently higher than that of the patients without postoperative upper GI bleeding.

2006-01-01

The purpose of this study is to determine the impact of edema on the dose delivered to the target volume. An evaluation of the edema characteristics was first made, and then a dynamical dosimetry algorithm was developed and used to compare its results to a standard clinical (static) dosimetry. Source positions and prostate contours extracted from 66 clinical cases on images taken at different points in time (planning, implant day, post-implant evaluation) were used, via the mean interseed distance, to characterize edema [initial increase (Δr 0 ), half-life (τ)]. An algorithm was developed to take into account the edema by summing a time series of dose-volume histograms (DVHs) with a weight based on the fraction of the dose delivered during the time interval considered. The algorithm was then used to evaluate the impact of edema on the dosimetry of permanent implants by comparing its results to those of a standard clinical dosimetry. The volumetric study yielded results as follows: the initial prostate volume increase was found to be 1.58 (ranging from 1.15 to 2.48) and the edema half-life, approximately 30 days (range: 3 to 170 days). The dosimetric differences in D 90 observed between the dynamic dosimetry and the clinical one for a single case were up to 15 Gy and depended on the edema half-life and the initial volume increase. The average edema half-life, 30 days, is about 3 times longer than the previously reported 9 days. Dosimetric differences up to 10% of the prescription dose are observed, which can lead to differences in the quality assertion of an implant. The study of individual patient edema resorption with time might be necessary to extract meaningful clinical correlation or biological parameters in permanent implants

Surgery comprised laparoscopically assisted radical vaginal hysterectomy (LARVH) (35.4%), radical abdominal hysterectomy (RAH) (48.4%), simple hysterectomy (HE) (11.5%) or exenteration (4.7%). Results: 73 patients had lymph node metastases, 119 had negative lymph nodes. In patients with LARVH 6-74 (median 30) lymph nodes were removed, with RAH 3-70 (median 21 lymph nodes), and after HE or exenteration 5-50 (median 13 lymph nodes). 90 patients had 25 or less lymph nodes removed, 83 patients more than 25 lymph nodes removed. Prognostic factors, such as age, FIGO stages, histologic grading and type of histology were well balanced in these cohorts. 45 (23.4%) of all patients developed clinically relevant lymph edema of the lower limb with a median latency of 11 (1-121) months. When 25 or less lymph nodes were removed 17.8% of patients developed leg edema, when more than 25 lymph nodes were removed 32.5% of patients were diagnosed with lymph edema (p = 0.025). Radiotherapy and chemotherapy had no influence on the incidence of leg edema. Overall survival at 5 (10) years was independent of number of lymph nodes removed. Conclusion: The data suggest increasing rates of leg edema with increasing number of lymph nodes dissected independent of the type of radiotherapy and chemotherapy performed. The lymph node sampling policy should be planned carefully in respect to minimize the risk of leg lymph edema. (orig.)

To evaluate the distribution of meibomian gland dropout and analyze the correlation between dropout and meibomian gland dysfunction (MGD). A total of 161 eyes of 85 patients with MGD were recruited as the MGD group; 88 eyes of 46 health volunteers were enrolled as the control group (2:1 matched for age and sex). Examinations included the Schirmer I test, breakup time, symptom questionnaire, corneal fluorescein staining, meibum quality, meibomian gland expressibility, and meibomian gland dropout. (1) The incidences of chalazion and eyelid surgery were significantly higher in patients with MGD. (2) All clinical indexes were better in healthy volunteers (all P dropout in the upper eyelid was statistically lower (P dropout than did the middle part, except in the lower eyelid of the control group. (4) The entire or partial dropout was positively related to MGD occurrence. Both additive dropout of the entire 2 eyelids and that of the 2 nasal parts had the strongest correlation (r = 0.792, P dropout (r = -0.229, P dropout of additive (r = 0.185, P dropouts exist in different or single eyelids. (2) Dropout evaluation is better when covering the entire area of both upper and lower meibomians. (3) Nasal part dropout plays a more essential role than the other dropouts in MGD occurrence.

Full Text Available AIM: To investigate the effects of Huoxuelishuimingmu Granules on corneal edema after phacoemulsification.METHODS: Ninety cases with at least second degree corneal edema the first day after phacoemulsification were randomly divided into the routinely treated group and the Huoxuelishuimingmu Granules intervened group, 45 cases for each group. To the routinely treated group, Tobramycin and Dexamethasone Eye Drops, Compound Tropicamide Eye Drops and Recombinant Bovine Basic Fibroblast Growth Factor Eye Drops were administered in turn during the treatment. While to the Huoxuelishuimingmu Granules intervened group, traditional Chinese medicines with the function of promoting blood circulation, alleviating water retention and removing nebula named Huoxuelishuimingmu Granules were additionally administered. The curative effects and the time taken for vanishment of corneal edema in each group were then observed. One week was counted as a course of treatment and curative effects were calculated after two courses.RESULTS: The Huoxuelishuimingmu Granules intervened group showed a much higher clinical cure rate and took quite shorter time for vanishment of corneal edema compared with the group treated with routine drugs(PP>0.05. CONCLUSION: Huoxuelishuimingmu Granules has a preferable clinical effect on corneal edema after phacoemulsification, shortening the duration of corneal edema and restoring the sight of patients in advance.

The objective was to assess the prevalence of lumbar facet joint edema in patients with low back pain. Lumbar spine MR examinations (1.5 T) of 145 consecutive patients (87 women, 58 men; mean age 52.8, range 17-94 years) were retrospectively evaluated with regard to the presence of facet joint edema. The MR protocol included sagittal short-tau inversion recovery (STIR), T1- and T2-weighted as well as transverse T2-weighted images. In 9 patients follow-up MR examinations were performed and results were compared with pain. The agreement between the change in intensity of facet joint edema and the change in intensity of pain was assessed using kappa statistics and Kendall's tau coefficient. In 21 of the 145 patients (14%) edema was found at the facet joints: in 52.4% at L4/5, in 19.0% at L5/S1, in 14.3% at L4/5 and L5/S1, in 9.5% at L3/4 and L4/5, and in 4.8% at L3/4. The agreement between the change in pain score and intensity of edema within the follow-up group was ''almost perfect'' (kappa = 0.81). Kendall's tau coefficient was 0.91, indicating high agreement. Sagittal STIR images detect facet joint edema in 14% of patients with low back pain. This fact may be useful for planning treatment including facet joint injections. (orig.)

Accurate measurement of edema volume is essential for the investigation of tissue response and recovery following a traumatic injury. The measurements must be noninvasive and repetitive over time so as to monitor tissue response throughout the healing process. Such techniques are particularly necessary for the evaluation of therapeutics that are currently in development to suppress or prevent edema formation. In this study, we propose to use optical coherence tomography (OCT) technique to image and quantify edema in a mouse ear model where the injury is induced by a superficial-thickness burn. Extraction of edema volume is achieved by an attenuation compensation algorithm performed on the three-dimensional OCT images, followed by two segmentation procedures. In addition to edema volume, the segmentation method also enables accurate thickness mapping of edematous tissue, which is an important characteristic of the external symptoms of edema. To the best of our knowledge, this is the first method for noninvasively measuring absolute edema volume. PMID:27282161

Of the many aspects of aesthetic surgery, the double-eyelid operation generates the most interest for Japanese surgeons, as there has been an enormous demand for it by patients who are fashion-conscious. It has been possible to locate 32 operative procedures that have been published in the Japanese literature over the past ninety years. Some of these procedures have been reviewed here in relation to the cultural and social changes which are important factors determining the extent of the demand for the operation and which correlate with various changes in surgical technique. This study chronologically describes each of the principal methods related to these social changes and also considers the influence of cultural fads and fashions.

During experiments with rats it has been established that preparations with a pronounced prophylactic effect on lung edema development in nonirradiated animals in some cases do not effect in such a way (or even aggravate the edema development) the irradiated animals (at 650 R dose). On the contrary ineffective or negatively effecting preparations in nonirradiated animals may exhibit a noticeable prophylactic effect on irradiated animals.

Full Text Available The change in difference between bioimpedance analysis (BIA and dual-energy X-ray absorptiometry (DEXA according to edema is an important issue for peritoneal dialysis (PD patients. We reviewed all adults who received PD. Patients had undergone two body composition measurements. 1108 cases were measured simultaneously by BIA and DEXA. Measurements were divided into four quartiles based on edema index. There were significant correlations and intraclass correlations between the two methods for lean mass (LM, fat mass (FM and bone mineral content. On a simple linear regression analysis, non-standardized-βs of total LM decreased as the grade of edema index increased (from 1.008 to 0.949. Those of total FM were increased as the grade of edema index increased (from 1.034 to 1.162. Bias for total LM changed to negative and negative bias increased as the grade of edema index increased (from 0.406 kg to –2.276 kg. There was a positive bias for total FM in first quartile and increased as the grade of edema index increased (from 0.594 kg to 2.863 kg. In conclusion, the present study demonstrates that BIA can measure normal hydrated LM in CAPD patients with edema. However, FM is overestimated in PD patients with edema. The difference between the two measurements increases as the grade of edema increases.

Calcineurin plays an important role in the development of neuronal excitability, modulation of receptor's function and induction of apoptosis in neurons. It has been established in kindling models that status epilepticus induces brain focal edema and astrocyte activation. However, the role of calcineurin in brain focal edema and astrocyte activation in status epilepticus has not been fully understood. In this study, we employed a model of lithium-pilocarpine-induced status epilepticus and detected calcineurin expression in hippocampus by immunoblotting, brain focal edema by non-invasive magnetic resonance imaging (MRI-7T) and astrocyte expression by immunohistochemistry. We found that the brain focal edema was seen at 24 h after status epilepticus, and astrocyte expression was obviously seen at 7 d after status epilepticus. Meanwhile, calcineurin expression was seen at24 h and retained to 7 d after status epilepticus. A FK506, a calcineurin inhibitor, remarkably suppressed the status epilepticus-induced brain focal edema and astrocyte expression. Our data suggested that calcineurin overexpression plays a very important role in brain focal edema and astrocyte expression. Therefore, calcineurin may be a novel candidate for brain focal edema occurring and intracellular trigger of astrogliosis in status epilepticus.

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.

Full Text Available Proper monitoring for volume overload is important to improve prognosis in peritoneal dialysis (PD patients. The association between volume status and residual renal function (RRF remains an unresolved issue. The aim of the present study was to evaluate the association between the edema index and survival or RRF in incident PD patients.We identified all adults who underwent PD. The edema index was defined as the ratio of extracellular fluid to total body fluid. Participants with available data regarding survivorship or non-survivorship during the first year after PD initiation were included in the area under the receiver operating characteristic curve analysis. The cutoff value of the edema index for 1-year mortality was >0.371 in men and >0.372 in women. Participants were divided into two groups according to the cutoff value of their baseline edema indices: High (>cutoff value and Low (≤ cutoff value. Survivors during the first year after PD initiation were divided into two groups according to the initial and 1-year edema index: Non-improvement (maintenance of criteria in the initial Low group during the year and Other (all participants except those in the Non-improvement group.In total, 631 patients were enrolled in the present study. The cutoff value of the edema index for 1-year mortality was >0.371 in men and >0.372 in women. The respective mean initial RRF values (mL · min(-1 · 1.73 m(-2 in the Low and High groups, respectively, were 4.88 ± 4.09 and 4.21 ± 3.28 in men (P = 0.108, and 3.19 ± 2.57 and 2.98 ± 2.70 in women (P = 0.531. There were no significant differences between groups in either sex. The respective mean RRF values at 1 year after PD initiation in the Low and High groups, respectively, were 3.56 ± 4.35 and 2.73 ± 2.53 in men, and 2.80 ± 2.36 and 1.85 ± 1.51 in women. RRF at 1 year after PD initiation was higher in the Low group than in the High group (men: P = 0.027; women: P = 0.001. In men, the cumulative 5-year

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.
