    Two late gestation Holstein cows about to begin the third lactation developed massive vulvar edema. These were the only affected animals in the herd of 500 milking cows. The vulvar edema spontaneously regressed postpartum for both cows. Massive vulvar swelling is seldom observed in dairy cows in advanced pregnancy and is not described in the literature.

  16. Vulvar lipoma: a case report

    PubMed Central

    2014-01-01

    Introduction Vulvar lipoma is a rare tumor localization and only a few cases have been reported. The clinical characteristics of vulvar lipoma are well known. However, it is important to distinguish lipomas from liposarcomas. We report a case of vulvar lipoma and discuss its clinical features, including diagnostic aspects, with emphasis on histopathological evaluation of all excised lesions. We also report and discuss patient management and treatment outcomes. Case presentation We report the case of a 27-year-old Moroccan woman. Our patient presented with a painless and slow-growing right vulvar mass that had evolved over one year, which had suddenly become uncomfortable when walking. A physical examination revealed a single soft and pasty mass in her left labium majus, which could be mobilized under her skin towards her mons pubis. The largest dimension of the mass measured 6cm. Magnetic resonance imaging showed a homogenous hyperintense mass with a well-defined contour in her left labium majus; a fat-suppressed magnetic resonance image demonstrated a marked signal intensity decrease. The mass was completely removed surgically. A histological examination revealed a circumscribed benign tumor composed of mature adipocytes, confirming the diagnosis of vulvar lipoma. Conclusion Vulvar lipomas must be differentiated from liposarcomas, which demonstrate very similar clinical and imaging profiles. The final diagnosis should be based on histopathological evaluation. A precise diagnosis should allow for appropriate surgical treatment. PMID:24946809

    Steroid induced skin atrophy is the most frequent and perhaps most important cutaneous side effect of topical glucocorticoid therapy. To date, it has not been described in vulvar skin. We describe a patient with significant vulvar skin atrophy following prolonged steroid application to treat vulvar dermatitis. The extensive atrophy in the perineum resulted in secondary ‘webbing’ and partial obstruction of genital hiatus and superimposed dyspareunia. Prolonged topical steroids may result in atrophic changes in vulvar skin. Therefore, further research in clinical correlates of steroid-induced atrophy in the vulvar region is warranted.

    Vulvar malignancies are important tumors of the female reproductive system. They represent a serious health issue with an incidence between 2 and 7 per 100,000 and year. We provide a review about most important cancer entities, i.e., melanoma, squamous cell carcinoma, basal cell carcinoma, neuroendocrine cancer, and skin adnexal malignancies.Squamous cell carcinoma is the most common vulvar malignancy that can develop from vulvar intraepithelial neoplasia or de novo. Basal cell carcinoma represents only 2% of all vulvar cancers. Melanoma of the vulva exists in two major types-superficial spreading and acral lentiginous. A special feature is the occurrence of multiple vulvar melanomas. Of the adnexal cancer types Paget's disease and carcinoma are seen more frequently than other adnexal malignancies. The dermatologist should be aware of this problem, since he might be the first to be consulted by patients for vulvar disease. Treatment should be interdisciplinary in close association to gynecologists, oncologists, and radiologists. PMID:25930015

    In this case report we describe the use of a 2-stage approach to treat severe recurrent vulvar lymphangiectasia in a patient with Noonan syndrome. First, 3 functional lymphatic vessels were identified and anastomosed to venules in an end-to-end fashion. Then, in a second surgical procedure, the vulvar lesions were resected as much as possible and the vulva was reconstructed. By the 12-month follow-up the patient had recovered well. Although there were still some small vesicles on the left labia there was no more ooze, itch, and pain. Lymphatic mapping using indocyanine green showed improvement of the edema of her vulva region and patent LVA. In addition to the demonstration of this 2-stage approach, this case report also demonstrates the benefits of preemptive LVA before performing surgery that may be at high risk for postoperative lymph edema.

    Vulvar carcinoma is an uncommon tumor that is seen most often in older women. Subtle symptoms such as pruritus should prompt examination and targeted biopsy in all women as this disease can be successfully treated even in elderly, frail individuals. Vulvar cancer has a bimodal age distribution and is seen in both young and older women with risk factors including human papillomavirus (HPV) infection, smoking, and vulvar skin diseases (i.e., lichen sclerosus). This cancer is staged surgically, with an update in 2009 incorporating prognostic factors. The treatment of vulvar carcinoma has evolved to include more conservative surgical techniques that provide improved cure rates with emphasis on minimizing morbidity. Advanced and metastatic lesions are now treated with chemoradiation which produces substantial cure rates with decreased morbidity. Promising areas of research in vulvar cancer include refinement of sentinel lymph node biopsy, prevention of lymphedema, and preservation of sexual function following treatment. PMID:25151473

    2015-11-01

    Vulvar cancer is uncommon, accounting for 0.3% of all new US cancer diagnoses. The majority of cases are squamous cell carcinoma. Malignant melanoma is the second most common type. Other cases are related to chronic inflammatory skin disorders such as lichen sclerosus. Vulvar intraepithelial neoplasia (VIN) is a precursor to squamous cell vulvar cancer. It may be the usual type associated with human papillomavirus (HPV) infection, or the differentiated type often associated with chronic skin disorders. Risk factors for VIN are HPV infection, cigarette smoking, chronic skin disorders, and immunosuppression. Symptoms of vulvar cancer include pruritus, bleeding, skin color change, skin lesions, and dysuria. VIN and vulvar cancer are diagnosed by skin biopsy. Treatment of VIN includes wide local excision, via surgical removal or with laser or ultrasonic surgical aspiration procedures. Medical therapy with imiquimod also may be used. Prognosis is good with early detection; the 5-year survival rate for stage I cancer is greater than 85%. Advanced disease has a poor prognosis, with a 5-year survival rate in stage IV disease as low as 5%. Although screening for vulvar cancer is not recommended, clinicians should evaluate and biopsy any suspicious vulvar lesions. Current efforts at prevention are aimed at HPV vaccination.

    Vulvar squamous cell carcinoma (VSCC) is a gynecological cancer with an incidence of two to three per 100,000 women. VSCC arises from vulvar intraepithelial neoplasia (VIN), which is diagnosed through painful punch biopsy. In this study, optical coherence tomography (OCT) is used to differentiate between normal and VIN tissue. We hypothesize that (a) epidermal layer thickness measured in OCT images is different in normal tissue and VIN, and (b) quantitative analysis of the attenuation coefficient (μoct) extracted from OCT data differentiates VIN from normal vulvar tissue. Twenty lesions from 16 patients are imaged with OCT. Directly after data acquisition, a biopsy is performed. Epidermal thickness is measured and values of μoct are extracted from 200 OCT scans of normal and VIN tissue. For both methods, statistical analysis is performed using Paired Mann-Whitney-test. Correlation between the two methods is tested using a Spearman-correlation test. Both epidermal layer thickness as well as the μoct are different between normal vulvar tissue and VIN lesions (p<0.0001). Moreover, no correlation is found between the epidermal layer thickness and μoct. This study demonstrates that both the epidermal thickness and the attenuation coefficient of vulvar epithelial tissue containing VIN are different from that of normal vulvar tissue.

  12. Committee Opinion No 673: Persistent Vulvar Pain.

    PubMed

    2016-09-01

    Persistent vulvar pain is a complex disorder that frequently is frustrating to the patient and the clinician. It can be difficult to treat and rapid resolution is unusual, even with appropriate therapy. Vulvar pain can be caused by a specific disorder or it can be idiopathic. Idiopathic vulvar pain is classified as vulvodynia. Although optimal treatment remains unclear, consider an individualized, multidisciplinary approach to address all physical and emotional aspects possibly attributable to vulvodynia. Specialists who may need to be involved include sexual counselors, clinical psychologists, physical therapists, and pain specialists. Patients may perceive this approach to mean the practitioner does not believe their pain is "real"; thus, it is important to begin any treatment approach with a detailed discussion, including an explanation of the diagnosis and determination of realistic treatment goals. Future research should aim at evaluating a multimodal approach in the treatment of vulvodynia, along with more research on the etiologies of vulvodynia. PMID:27548558

    2014-01-01

    Background Vulvar defects result chiefly from oncologic resection of vulvar tumors. Reconstruction of vulvar defects restores form and function for the purpose of coitus, micturition, and defecation. Many surgical options exist for vulvar reconstruction. The purpose of this article is to present our experience with vulvar reconstruction. Methods From 2007 to 2013, 43 women presented to us with vulvar defects for reconstruction. Their mean age at the time of reconstruction was 61.1 years. The most common cause of vulvar defect was from resection of vulvar carcinoma and extramammary Paget's disease of the vulva. Method s of reconstruction ranged from primary closure to skin grafting to the use of pedicled flaps. Results The main complications were that of long term hypertrophic and/or unaesthetic scarring of the donor site in 4 patients. Twenty-two patients (51%) were able to resume sexual intercourse. There were no complications of flap loss, wound dehiscence, and urethral stenosis. Conclusions We present a subunit algorithmic approach to vulvar reconstruction based on defect location within the vulva, dimension of the defect, and patient age and comorbidity. The gracilis and gluteal fold flaps are particularly versatile and aesthetically suited for reconstruction of a variety of vulvar defects. From an aesthetic viewpoint the gluteal fold flap was superior because of the well-concealed donor scar. We advocate the routine use of these 2 flaps for vulvar reconstruction. PMID:25075361

    2013-02-01

    The subepidermal hormonally sensitive tissue of the vulva is anatomically unique and may give rise to a wide variety of vascular tumors. As a consequence, classifying vulvar vascular lesions has been challenging due both to the wide variety of lesions that may be encountered and the heterogeneity in reporting across several disciplines. The purpose of this study is to present an institutional experience of vulvar vascular lesions. Overall, 85 patients were identified over a 26-year period. Vascular lesions belonging to the following classes included (n, %total) benign vascular tumors (32, 38%), dilatations of preexisting vessels (31, 36%), hyperplasia/reactive (7, 8%), tumors with significant vascular component (11, 13%), malformations (3, 4%), and malignant vascular tumors (1, 1%). Two reaction patterns based on vulvar lymphatic pathology were identified: one is a stromal dominant pattern and the other is a vascular dominant pattern. Vulvar vascular malformations and true vascular malignancies, although rare, may have associated high morbidity. To accurately classify vulvar lymphatic lesions, the pathologist must carefully consider the patient's clinical history taking into account features such as preexisting lymphedema. PMID:23348141

    2016-04-01

    Vulvar lymphangioma circumscriptum (LC) is a rare entity which may present as a painful, warty lesion. In contrast to the congenital form, which occurs in children, the acquired form arises in older adults and may be associated with infection, Crohn's disease, or prior pelvic/regional surgery. We present a case of acquired LC of the vulva in a 55-year-old woman who presented with a 3-4 year history of vulvar pain following chemotherapy, radiation, and brachytherapy for cervical cancer. Vulvar shave biopsies followed by excision revealed a thickened dermis with epidermal hyperkeratosis, parakeratosis, elongated rete ridges and dilated lymphatic channels containing eosinophilic material and scattered thrombi. The differential diagnosis for this unusual lesion includes more common conditions such as condyloma acuminatum, fungating squamous cell carcinoma and molluscum contagiosum. It is important to recognize the clinical presentation as well as the distinct histological appearance of this rare benign entity. PMID:27331134

  20. ACOG Committee Opinion No. 509: Management of vulvar intraepithelial neoplasia.

    PubMed

    2011-11-01

    Vulvar intraepithelial neoplasia (VIN) is an increasingly common problem, particularly among women in their 40s. The term VIN is used to denote high-grade squamous lesions and is subdivided into usual-type VIN (including warty, basaloid, and mixed VIN) and differentiated VIN. Usual-type VIN is commonly associated with carcinogenic genotypes of human papillomavirus (HPV) and other HPV persistence risk factors, such as cigarette smoking and immunocompromised status, whereas differentiated VIN usually is not associated with HPV and is more often associated with vulvar dermatologic conditions, such as lichen sclerosus. Biopsy is indicated for any pigmented vulvar lesion. Treatment is indicated for all cases of VIN. When occult invasion is not a concern, VIN can be treated with surgical therapy, laser ablation, or medical therapy. After resolution, women should be monitored at 6 and 12 months and annually thereafter. PMID:22015906

    2014-01-01

    The objective of this paper is to present general considerations which should be kept in mind by clinicians in charge of women with vulvar diseases. Four representative vulvar dermatoses are described. Lichen simplex chronicus is a pathological condition related to chemical and mechanical irritant agents. Detrimental effects of these irritants, in the presence of other dermatoses, have to be considered when therapeutic responses are unsatisfactory. Lichen sclerosus is the most common vulvar dermatosis in elderly. However, it should be kept in mind that it may be diagnosed at any age. Lichen planus, in spite of sharing a similar range of etiological factors with lichen sclerosus, is a very distinct entity. Finally, Paget's disease, although rare, is also described especially because of the challenge it represents both clinically and therapeutically. PMID:24511539

    Women with vulvar vestibulitis syndrome (VVS) suffer from severe pain and discomfort in the area around the introitus at almost any stimulus that causes pressure within the vestibule. In spite of the severe sensory symptoms present in these women, the influence of the peripheral nerves in the vulvar vestibulum has not been clarified before. In this study the nerve supply in the vestibular mucosa in women with VVS and in healthy women free from vulvar symptoms has been revealed by PGP 9.5 immunohistochemistry. The results show a significant increase in the number of intraepithelial nerve endings in women with VVS, indicating an alteration in the nerve supply in the afflicted area. PMID:9813445

    When assessing women with chronic vulvar pain, women's health physical therapists search for comorbid mechanical components (including musculoskeletal, fascial, and visceral) and other disorders that may contribute to or be caused by chronic vulvar pain (CVP). Pelvic floor hypertonicity is a key perpetuating factor for CVP. Comprehensive physical therapy evaluation and suggested physical therapy interventions are described. Anatomy of the pelvis, common evaluative findings, and specifics for pelvic floor muscle rehabilitation are presented. Normalization of pelvic floor muscle function contributes to the reduction of CVP. Successful treatment includes the identification and treatment of co-existing physical abnormalities throughout the trunk and pelvis. PMID:20868404

    Cellular angiofibroma is a mesenchymal tumor that affects both genders. Nucci et al. first described it in 1997. Cellular angiofibroma is generally a small and asymptomatic mass that primarily arises in the vulvar-vaginal region, although rare cases have been reported in the pelvic and extrapelvic regions. It affects women most often during the fifth decade of life. The treatment requires simple local excision due to low local recurrence and no chance of metastasization. The current study presents a case of angiofibroma in the vulvar region that measured approximately 20 cm. PMID:27293929

    Vulvar or vaginal neoplasia was diagnosed in 99 dogs. The most common clinical sign was vulvar discharge or the sudden appearance of a protruding mass from the vulva. Most of the dogs were old (average age, 10.8 years) and sexually intact. Of the 99 tumors, 72 were benign, 17 were malignant, and 10 were transmissible venereal tumors. Except for the transmissible venereal tumors, most tumors were of smooth muscle or fibrous tissue origin (leiomyoma, fibroma, and leiomyosarcoma). In the dogs with benign tumors, surgical excision of the tumor combined with ovariohysterectomy was effective in preventing recurrence of disease. PMID:6629979

    Two camels (Camelus dromedarius), 3- and 4-years-old, respectively, from an eastern Tennessee wildlife farm presented with persistent weight loss and large vulvar masses. An initial biopsy of the vulvar mass of one of the camels performed by a local veterinarian showed eosinophilic dermatitis. An allergic or parasitic dermatitis was suspected. The two camels were treated with one dose of sodium iodide (66 mg/kg, in 1.0 L of normosolR, IV) and ivermectin 1% (200 ug/kg PO). Upon presentation at the Veterinary Teaching Hospital, University of Tennessee, additional biopsies of the masses again revealed eosinophilic dermatitis. Microscopic examination of a Gomori methenamine silver (GMS)-stained section prepared from the biopsy of one of the camels revealed the presence of fungal-like hyphae of a mold which was suspected to be Pythium insidiosum. The vulvar masses were surgically debulked in both animals and sodium iodide and Pythium-immunotherapy prescribed. Pythium insidiosum was isolated in culture and hyphae elements were detected in histological sections confirming the diagnosis of pythiosis in both animals. Despite signs of progressive healing of the vulvar surgical areas, postoperative persistent weight lost in one of the camels suggested the possibility of gastro intestinal (GI) tract pythiosis. This camel died 5 months after the first onset of clinical signs and unfortunately a necropsy was not performed. The other camel responded well to the combination of surgery, iodides, and immunotherapy and has currently rejoined the other members of the herd. PMID:21696258

    Squamous cell carcinoma of the vulva is a disease of significant clinical importance, which arises in the presence or absence of human papillomavirus. We used comparative genomic hybridisation to document non-random chromosomal gains and losses within human papillomavirus positive and negative vulvar cancers. Gain of 3q was significantly more common in human papillomavirus-positive cancers compared to human papillomavirus-negative cancers. The smallest area of gain was 3q22-25, a chromosome region which is frequently gained in other human papillomavirus-related cancers. Chromosome 8q was more commonly gained in human papillomavirus-negative compared to human papillomavirus-positive cancers. 8q21 was the smallest region of gain, which has been identified in other, non-human papillomavirus-related cancers. Chromosome arms 3p and 11q were lost in both categories of vulvar cancer. This study has demonstrated chromosome locations important in the development of vulvar squamous cell carcinoma. Additionally, taken together with previous studies of human papillomavirus-positive cancers of other anogenital sites, the data indicate that one or more oncogenes important in the development and progression of human papillomavirus-induced carcinomas are located on 3q. The different genetic changes seen in human papillomavirus-positive and negative vulvar squamous cell carcinomas support the clinicopathological data indicating that these are different cancer types.

    OBJECTIVE. The aim of this study was to evaluate the efficacy of fat grafting in the treatment of severe vulvar lichen sclerosus (LS). Our primary outcome was to assess the improvement of mucocutaneous trophism, the resolution/reduction of symptoms, and the histological features of the vulvar skin after treatment. The secondary outcome was to evaluate the improvement in life quality, and in resumption and quality of sexual life. METHODS. Between 2011 and 2014, 36 patients were offered fat grafting to treat LS. Inclusion criteria were age between 25 and 80 years, histopathologic diagnosis of LS, good health, failure of previous first line treatments. RESULTS. 34 out of 36 patients (94%) showed a better vulvar trophismof the skin and mucosae; 27 (75%) had an improvement in caliber and elasticity of the vaginal introitus; clitoris burying degree was reduced in 18 patients (50%), 30 (83%) reported an increased volume of labia major a and minor a, 34 (94%) had a complete disappearance of scratching lesions, and 28 (78%) showed a remission of white lesions. Eventually 34 patients (95%) stopped using topical corticosteroids routinely. The improvement in life quality was significant for both DLQI (p b 0001) and FSFI (p b 0001). CONCLUSIONS. Fat grafting may have a role as a support and completion treatment in selected cases of women with vulvar LS who do not respond to first line therapy or in severe cases where the anatomical impairment does not allow a regular sexual function and a good quality of life.

    The vulva is a particularly common locus of chronic pain with neuropathic characteristics that occurs in women of any age, though most women with neuropathic type chronic vulvar pain will remain undiagnosed even following multiple physician visits. Here, we report on an exemplary case of a middle-aged woman who was referred to the Vulvovaginal Disease Clinic with debilitating vulvar burning and itching over the right labium majus that had been persisting for 2 years and was considered intractable. Careful history taking and clinical examination, followed by electrophysiological assessment through somatosensory evoked potentials was consistent with genitofemoral neuralgia, for which no obvious cause could be identified. Adequate pain relief was obtained with a serotonin–noradrenaline reuptake inhibitor and topical gabapentin cream. We briefly discuss the epidemiology, diagnosis, and treatment of genitofemoral neuralgia and provide a series of clues to guide clinicians in obtaining a presumptive diagnosis of specific neuropathic pain syndromes that may underlie chronic vulvar pain. We further aim to draw attention to the tremendous burden of chronic, unrecognized vulvar pain. PMID:26664155

    The decrease of lung compliance in pulmonary edema underlies ventilator-induced lung injury. However, the cause of the decrease in compliance is unknown. We tested the hypothesis that in pulmonary edema, the mechanical effects of liquid-filled alveoli increase tissue stress in adjacent air-filled alveoli. By micropuncture of isolated, perfused rat lungs, we established a single-alveolus model of pulmonary edema that we imaged using confocal microscopy. In this model, we viewed a liquid-filled alveolus together with its air-filled neighbor at different transpulmonary pressures, both before and after liquid-filling. Instilling liquid in an alveolus caused alveolar shrinkage. As a result, the interalveolar septum was stretched, causing the neighboring air-filled alveolus to bulge. Thus, the air-filled alveolus was overexpanded by virtue of its adjacency to a liquid-filled alveolus. Confocal microscopy at different depths of the liquid-filled alveolus revealed a meniscus. Lung inflation to near-total lung capacity (TLC) demonstrated decreased compliance of the air-filled but not liquid-filled alveolus. However, at near TLC, the air-filled alveolus was larger than it was in the pre-edematous control tissue. In pulmonary edema, liquid-filled alveoli induce mechanical stress on air-filled alveoli, reducing the compliance of air-filled alveoli, and hence overall lung compliance. Because of increased mechanical stress, air-filled alveoli may be susceptible to overdistension injury during mechanical ventilation of the edematous lung. PMID:20118224

    Despite of the fact that the vulva contains a high density of apocrine and anogenital mammary glands in addition to eccrine glands and folliculosebaceous units, the benign vulvar adnexal tumours are rare. Though the varied clinical presentation and diverse histopathological spectrum of vulvar neoplasms has amazed the pathologists, only few studies have been reported in literature. The present five year study consists of only five cases of benign vulvar neoplasms depicting their rarity. Hidradenoma papilliferum and syringoma were the most common entities followed by Chondroid syringoma. The aim of our study is to explore and highlight the histopathological diversity of benign vulvar adnexal tumours reflecting the relative frequency of these structures. PMID:27047567

    A number of reports associate human papillomavirus (HPV) with cervical cancer and cancer cell lines derived from this tumour type. Considerably fewer reports have focused on the role of HPV in carcinomas from other sites of female anogenital squamous epithelia. In this study we have tested for the presence of HPV in eight low-passage vulvar carcinoma cell lines and one extensively passaged cell line, A431. One cell line from a primary vaginal carcinoma was included. The presence of the HPV was evaluated by the polymerase chain reaction (PCR), by Southern blot analysis and by two-dimensional gel electrophoresis. General primer-mediated PCR was applied by using primers from the L1 region, E1 region and HPV 16 E7 region. Southern blot hybridisation was performed under low-stringency conditions (Tm = -35 degrees C) using a whole genomic HPV 6/16/18 probe mixture and under high stringency conditions (Tm = -18 degrees C) with the whole genomic probes of HPV 16 and 33. HPV 16 E6-E7 mRNA was assessed by ribonuclease protection assay (RPA). HPV was found in only one vulvar carcinoma cell line, UM-SCV-6. The identified type, HPV 16, was integrated in the cell genome and could be amplified with all primers used. Also E6-E7 transcripts were found in these cells. Five original tumour biopsies were available from the HPV-negative cell lines for in situ hybridisation. All these were HPV negative with both the HPV 6/16/18 screening probe mixture under low stringency and the HPV 16 probe under high stringency. The results indicate that vulvar carcinoma cell lines contain HPV less frequently than cervical carcinoma cell lines and suggest that a significant proportion of vulvar carcinomas may evolve by an HPV-independent mechanism.

    Vulvar cancer is the fourth most common gynecological cancer worldwide. However, limited studies have been completed on the molecular characterization of vulvar squamous cell carcinoma resulting in a poor understanding of the disease initiation and progression. Analysis and early detection of the precursor lesion of HPV-independent vulvar squamous cell carcinoma (VSCC), differentiated vulvar intraepithelial neoplasia (dVIN), is of great importance given dVIN lesions have a high level of malignant potential. Here we present an examination of adjacent normal vulvar epithelium, dVIN, and VSCC from six patients by peptide Matrix-assisted laser desorption/ionization Mass Spectrometry Imaging (MALDI-MSI). The results reveal the differential expression of multiple peptides from the protein cytokeratin 5 (CK5) across the three vulvar tissue types. The difference observed in the relative abundance of CK5 by MALDI-MSI between the healthy epithelium, dVIN, and VSCC was further analyzed by immunohistochemistry (IHC) in tissue from eight VSCC patients. A decrease in CK5 immunostaining was observed in the VSCC compared to the healthy epithelium and dVIN. These results provide an insight into the molecular fingerprint of the vulvar intraepithelial neoplasia that appears to be more closely related to the healthy epithelium than the VSCC. PMID:27399691

    The optical coherence tomography (OCT), a noninvasive and noncontact diagnostic method, was introduced in 1995 for imaging macular diseases. In diabetic macular edema (DME), OCT scans show hyporeflectivity, due to intraretinal and/or subretinal fluid accumulation, related to inner and/or outer blood-retinal barrier breakdown. OCT tomograms may also reveal the presence of hard exudates, as hyperreflective spots with a shadow, in the outer retinal layers, among others. In conclusion, OCT is a particularly valuable diagnostic tool in DME, helpful both in the diagnosis and follow-up procedure.

    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

Up to 30 % of the cases are diagnosed in a clinical condition of irresectability, and some kind of strategy has to be taken into account beyond surgery. In this regard, a common and standard definition is critical to maximize oncological results and minimize complications after treatments.

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.

    Human papillomavirus (HPV) infection is in the vast majority of patients accountable for the development of vulvar, cervical and vaginal intraepithelial neoplasia (VIN, CIN, VAIN); precursors of vulvar, cervical and vaginal cancers. The currently preferred treatment modality for high grade VIN, CIN and VAIN is surgical excision. Nevertheless surgical treatment is associated with adverse pregnancy outcomes and recurrence is not uncommon. The aim of this review is to present evidence on the efficacy, safety and tolerability of imiquimod (an immune response modifier) in HPV-related VIN, CIN and VAIN. A search for papers on the use of imiquimod in VIN, CIN and VAIN was performed in the MEDLINE, EMBASE and Cochrane library databases. Data was extracted and reviewed. Twenty-one articles met the inclusion criteria and were analyzed; 16 on VIN, 3 on CIN and 2 on VAIN. Complete response rates in VIN ranged from 5 to 88%. Although minor adverse effects were frequently reported, treatment with imiquimod was well tolerated in most patients. Studies on imiquimod treatment of CIN and VAIN are limited and lack uniformly defined endpoints. The available evidence however, shows encouraging effect. Complete response rates for CIN 2-3 and VAIN 1-3 ranged from 67 to 75% and 57 to 86% respectively. More randomized controlled trials on the use of imiquimod in CIN, VAIN and VIN with extended follow-up are necessary to determine the attributive therapeutic value in these patients. PMID:26335596

    Ectopic breast tissue is defined as glands located outside of the breast. Ectopic breast tissue should be excised because it may develop benign (fibroadenoma) or malignant pathologic processes. Less than forty cases of fibroadenomas have been reported in the literature. Although lactation changes can occur, lactating adenoma in the vulva are extremely rare. Only four cases have been reported. We report a case of a young woman who presented with vulvar mass during her lactation. The mass was excised, and histology confirmed vulvar lactating adenoma associated with fibroadenoma. This is the first case of vulvar heterotopic breast lesion associating lactating adenoma and fibroadenoma. PMID:23330038

    Vulvar and vaginal atrophy (VVA) is a common and progressive medical condition in postmenopausal women. The REVIVE (REal Women's VIews of Treatment Options for Menopausal Vaginal ChangEs) survey assessed knowledge about VVA and its impact in 3,046 postmenopausal U.S. women, and recorded women's attitudes about their interactions with health care providers and about available treatments. REVIVE identified poor disease awareness and understanding among women, failure of health care professionals to evaluate women for VVA signs and symptoms, low treatment rates and concerns about the safety and efficacy of available therapies. Strategies to address these needs include proactive screening, education for women and clinicians about VVA and recommendations for treatment and follow-up. PMID:26264795

    Purpose: To investigate dosimetric predictors of laryngeal edema after radiotherapy (RT). Methods and Materials: A total of 66 patients were selected who had squamous cell carcinoma of the head and neck with grossly uninvolved larynx at the time of RT, no prior major surgical operation except for neck dissection and tonsillectomy, treatment planning data available for analysis, and at least one fiberoptic examination of the larynx within 2 years from RT performed by a single observer. Both the biologically equivalent mean dose at 2 Gy per fraction and the cumulative biologic dose-volume histogram of the larynx were extracted for each patient. Laryngeal edema was prospectively scored after treatment. Time to endpoint, moderate or worse laryngeal edema (Radiation Therapy Oncology Group Grade 2+), was calculated with log rank test from the date of treatment end. Results: At a median follow-up of 17.1 months (range, 0.4- 50.0 months), the risk of Grade 2+ edema was 58.9% {+-} 7%. Mean dose to the larynx, V30, V40, V50, V60, and V70 were significantly correlated with Grade 2+ edema at univariate analysis. At multivariate analysis, mean laryngeal dose (continuum, hazard ratio, 1.11; 95% confidence interval, 1.06-1.15; p < 0.001), and positive neck stage at RT (N0-x vs. N +, hazard ratio, 3.66; 95% confidence interval, 1.40-9.58; p = 0.008) were the only independent predictors. Further stratification showed that, to minimize the risk of Grade 2+ edema, the mean dose to the larynx has to be kept {<=}43.5 Gy at 2 Gy per fraction. Conclusion: Laryngeal edema is strictly correlated with various dosimetric parameters; mean dose to the larynx should be kept {<=}43.5 Gy.

    Objective Chronic vulvar pruritus and vulvodynia are common vulvar diseases. The aim of this study was to compare gynecological and sexual and physical abuse histories from patients with these diagnoses, and from healthy controls. Materials and Methods Questionnaires were self-completed by patients diagnosed with vulvar itch-scratch (n= 93), vulvodynia (n= 232), and patients presenting for annual gynecological examinations (n= 104) at the University of Michigan Hospitals, Ann Arbor, Michigan. Results Patients who came for annual examinations were less likely to report past gynecological infections (p < 0.05) and indicated higher interest in and more frequent sexual activity than the other two groups (p = 0.003). Vulvodynia patients had the highest scores on the McGill Pain Questionnaire (p < 0.001). Subjects with either vulvar disorder were more likely to self-report a history of gynecologic infections than annual examination controls. Rates of sexual (p = 0.78) and physical abuse (p = 0.12) were similar for all three groups. Conclusions Patients with vulvar pruritus and vulvodynia report similar rates of sexual and physical abuse.

    Hereditary angioneurotic edema results from the deficiency of C1-esterase inhibitor. The clinical picture of this autosomal dominant disorder is characterized by recurrent attacks of edema formation in the subcutis and/or the submucosa. The clinical records of 21 children with established hereditary angioneurotic edema were reviewed. Follow-up care included laboratory check-ups and abdominal ultrasound. Clinical manifestations of the disease first occurred in 2.5 to 12 years of age. Mechanical trauma was the most common precipitating factor. Pedigree-analysis revealed 19 patients with afflicted relatives. Long-term prophylaxis was initiated with tranexamic acid and danazol in 10 cases; 2 children required short-term prophylaxis. Therapy improved serum complement parameters significantly and reduced the frequency and severity of clinical manifestations. Acute, life-threatening edematous attacks were treated by the administration of C1-inhibitor concentrate, which achieved the resolution of the edema within several hours. Abdominal ultrasonography performed during the attack invariably demonstrated transitory ascites that resolved spontaneously after treatment. Adequate prophylaxis and follow-up care can spare pediatric patients from edematous attacks. Undesirable adverse effects can be avoided and the patient's quality of life can be enhanced considerably by administering the lowest effective drug dose. PMID:11143287

    HEALTH ISSUE: In Canada, cancers of the endometrium, ovaries, vulva, vagina, placenta and adnexa account for 11% of all malignant neoplasms in women and 81% of all genital cancers. Although the incidence and mortality from vulvar and vaginal cancers are very low, endometrium and ovarian cancer are important public health problems. KEY FINDINGS: In Canada, there has been no appreciable improvement in survival for women with advanced endometrial (EC) or ovarian cancer (OC) over the past 30 years. The prognosis of EC is good for most patients because diagnosis is made at early stages. However, survival of OC is poor; more than 70% of cases are diagnosed at late stages. Up to 10% of OCs is linked to familial aggregation. Cancers of the vulva and of the vagina are very rare. The survival experience for women with the latter is worse than for those with the former. Both share many risk factors with cervical cancer and the recent developments in the study of HPV infection should be applicable to these diseases as well. Of particular interest will be the advent of vaccines for the primary prevention of HPV infection. DATA GAPS AND RECOMMENDATIONS: At present, the best available means to diagnose gynecologic malignancies is a detailed clinical examination, considering the totality of information on potential and proven risk factors, such as age, reproductive health, sexual practices, use unopposed estrogens or of oral contraceptives or tubal ligation, obesity, diet, smoking, and the familial clustering of some of these cancers.

    Vulvar vestibulitis syndrome (VVS) is a long lasting disorder of superficial dyspareunia in young women. Quantitative sensory testing, including mechanical and temperature pain thresholds and warm/cold difference limen (WCL), was performed in the vestibular mucosa in 22 women (mean age 25.0 years) with vestibulitis and 20 control subjects (mean age 25.6 years). The tests were carried out on days 7-11 of the menstrual cycle. Patients had allodynia to mechanical testing with von Frey filaments, 14.3+/-3.1mN in the symptomatic posterior area as compared with 158+/-33.5mN in healthy subjects, P<0.0001. The pain threshold to heat was 38.6+/-0.6 degrees C in patients and 43.8+/-0.8 degrees C in controls, P<0.0001. In addition, pain threshold to cold was 21.6+/-1.2 degrees C in patients whereas cooling down to 6 degrees C was usually not painful in controls. WCL was 4.9+/-0.5 degrees C in patients and 9.6+/-1.5 degrees C in healthy subjects, P<0.01. The results are compatible with the hypothesis that patients with VVS have an increased innervation and/or sensitization of thermoreceptors and nociceptors in their vestibular mucosa. PMID:11690731

    About 100 million women are estimated to be circumcised globally. Various rates of complications have been encountered, especially after circumcision, such as bleeding, infection, shock, menstrual irregularity, difficulty in urination or common urinary tract infections, inguinal pain, difficulty in sexual intercourse, and genital circumcision scar especially at the vulvar region, and cystic or solid character mass in short and long term. Furthermore, the maternal-fetal morbidity and mortality increase due to bleeding and fistula, which develop after prolonged labor, travail, and difficult labors. Our aim in this paper was to discuss a 42-year-old multiparous female case who had undergone type 2 radical genital mutilation (circumcision) when she was 7 years of age, along with the literature, which has been evaluated for the gradually growing mass at the left inguinal canal region in the last 10 years and diagnosed as epidermoid inclusion cyst developing secondary to postcircumcision surgical ground trauma, since there was no other case found in the literature search that had been circumcised at such an early age and developing after circumcision at such advanced age, and, therefore, this is suggested to be the first case on this subject.

    Malignant melanoma of the vulva and vagina is relatively uncommon and accounts for <5% of all melanomas in women. The aim of our study was to establish the biological properties and evaluate potential therapeutic targets in these tumors. We collected a series of 65 cases from three centers and re-evaluated the tumor tissue for predominant growth pattern (superficial spreading, nodular, and mucosal lentiginous) and tumor thickness. KIT (CD117) expression was detected immunohistochemically. In addition, tumors were screened for BRAF, NRAS, and KIT mutations by PCR and DNA sequencing as well as for KIT amplifications by fluorescence in situ hybridization. None of the cases contained BRAF mutations. NRAS mutations and KIT amplifications were detected in similar frequency (∼12%) in tumors of the vulva and vagina. In contrast, KIT mutations were present in 18% of primary melanomas of the vulva, but in none of the tumors arising in the vagina. Moderate or strong KIT protein expression was detected in 30 cases, including all tumors with KIT mutations and 6 of the 7 with KIT amplifications. In conclusion, BRAF mutations are virtually absent in melanomas originating from the vulva or vagina, whereas NRAS mutations and KIT amplifications occur in both locations. KIT mutations appear to be specific for melanomas of the vulva, suggesting that in spite of the anatomic proximity, the development of vulvar and vaginal melanomas involves different molecular alterations which may be targeted by novel treatment approaches.

    Methylchloroisothiazolinone/methylisothiazolinone is a preservative found in cosmetic and industrial products, and is a common ingredient in moist toilet paper. It is a well-known allergen and is capable of causing allergic contact dermatitis.We present the case of a 58-year-old white woman with a cutaneous vulvar eruption with associated discomfort and pruritus of 6 months in duration. She had been treated with antibiotic and antifungal agents without improvement of symptoms. Careful history taking revealed that the patient was using moist toilet paper. Patch testing confirmed an allergy to methylchloroisothiazolinone, a preservative in the moist toilet paper. After discontinuation of the product and treatment with potent topical steroids, the eruption completely cleared.With the growing use of moist toilet paper among adults, the risk of exposure and potential sensitization is increasing. Health care providers should be aware of the risks of moist toilet paper containing potential allergens because perianal and perineal dermatitis caused by these products may be unrecognized or misdiagnosed. After proper treatment, patients must be educated about alternatives and the importance of label reading. PMID:23760148

    Vulvar squamous cell carcinoma (VSCC) is a rare female genital neoplasm. Although numerous molecular changes have been reported in VSCC, biomarkers of clinical relevance are still lacking. On the other hand, there is emerging evidence on the use of mtDNA as a diagnostic tool in oncology. In order to investigate mtDNA status in VSCC patients, haplogroup distribution analysis and D-loop sequencing were performed. The results were compared with available data for the general Polish population, cancer free-centenarians as well as patients with endometrial and head and neck cancer. The obtained data were also compared with the current status of mitochondrial databases. Significant differences in haplogroup distribution between VSCC cohort, general Polish population and cancer-free centenarians cohort were found. Moreover, a correlation between the VSCC patients haplogroup and HPV status was observed. Finally, a specific pattern of mtDNA polymorphisms was found in VSCC. Our results suggest that the mitochondrial genetic background may influence the risk of VSCC occurrence as well as susceptibility to HPV infection. PMID:20825678

    Infections of the vulva can present a complex differential to the gynecologist, ranging from superficial skin infections to lifethreatening necrotizing fasciitis. Recognition and timely treatment remain universal to skin and soft-tissue infections as the subcutaneous anatomy of the vulva can facilitate rapid spread to other tissues with significant morbidity and mortality. Employing a multidisciplinary team approach to care for vulvar cellulitis and abscess can guide treatment from antibiotic therapies to more aggressive surgical debridement. In this report, we describe a case of vulvar abscess caused by Methicillin-resistant staphylococcus aureus (MRSA) in a postmenopausal woman with underlying diseases of bronchiectasis and atelectasis.

    We present the case of a 68-year-old woman with acute pulmonary edema secondary to the administration of naloxone to reverse an inadvertent narcotic overdose. The patient presented following a 12-hour history of increasingly bizarre behavior and confusion. A total IV dose of 1.6 mg naloxone was administered in an attempt to reverse the suspected overconsumption of a codeine-containing cough suppressant. She immediately became agitated, tachycardic, and diaphoretic; a clinical diagnosis of acute pulmonary edema was made. Following treatment with furosemide, nitroglycerin, and morphine sulfate, the patient recovered completely without further incident. Although naloxone is thought to be a safe drug with few complications, it should not be used indiscriminantly, and the smallest doses necessary to elicit the desired response should be used.

    Hyskon (32 percent dextran-70) (Hyskon Division, Pharmacia) is used during hysteroscopy to help visualization of the uterine surfaces. Pulmonary edema of an uncertain cause has occurred in many patients. Because this study could not be conducted in humans, we determined if Hyskon caused cardiogenic or non-cardiogenic pulmonary edema in a dog model. Dogs were randomly assigned to receive an infusion of Hyskon or whole blood to sustain left ventricular end-diastolic pressure between 20 and 23 millimeters of mercury for 60 minutes. In dogs receiving blood, there was no protein in the bronchoalveolar lavage before or after blood was given. In the Hyskon group, there was no protein in the bronchoalveolar lavage before Hyskon and 0.6 +/- 1.4 milligrams per deciliter (range of 0.1 to 3.7 milligram per deciliter) after Hyskon. The ratio of bronchoalveolar lavage protein to plasma protein after Hyskon was 8.0 +/- 18.0 percent compared with zero percent in the blood group. Hyskon altered pulmonary microvascular membrane permeability, causing alveolar flooding with plasma proteins and possibly accounting for the deterioration of oxygenation and pulmonary compliance seen in patients. These results suggest a significant noncardiogenic component of Hyskon induced pulmonary edema. PMID:7505487

    This paper continues the series of studies introducing holistic approach to analysis of clinical data. Namely, besides the information regarding his/her disease, each hospitalized cancer patient also provides the variety of data regarding his/her psychological, cultural, social, economical, genetic, constitutional and medical background. The aim of this study was to introduce a holistic approach to analysis of medical data, in this case clinical data regarding cancer of the vulva. Such approach requires the collection of data regarding different aspects of the cancer patients, and after the satisfactory sample size is obtained (which should be at least five times greater than the number of examined patient characteristics), the performance of factor analysis. In this study, the authors have processed the data regarding 25 characteristics of all 755 vulvar cancer patients treated between 1938 and 1990 at the Department for Gynecological Oncology of the University Hospital for Gynecology and Obstetrics, Zagreb, Croatia. In factor analysis, the principal components were rotated after the initial extraction (the authors recommended the use of oblimin rotation) in order to obtain better ground for interpretation of the obtained results. The next step in this approach was the stepwise exclusion of characteristics with smallest commonality according to Kaiser-Meyer-Olkin criteria, and retaining the characteristics and components with the most significant impact on the explained system variance. When the number of principal components and initial analyzed characteristics was reduced to 3-4 and 7-10, respectively, the ultimate interpretations and conclusions were made. This approach outlined some clusters of correlations between medical data which are difficult to identify using other statistical procedures, primarily the impacts of various socioeconomic and hereditary-constitutional variables on overall survival.

    OBJECTIVE: To evaluate the risk of vulvar vestibulitis syndrome (VVS) associated with genital infections in a case-control study. METHODS: Diagnosed cases with VVS (n = 69) and age-frequency-matched healthy controls (n = 65) were enrolled from gynecology clinics in a university medical hospital during 1999. They were compared for potential risk factors and symptoms of disease. RESULTS: VVS cases had a significantly higher risk of physician-reported bacterial vaginosis (BV) (odds ratio, OR = 9.4), Candida albicans (OR = 5.7), pelvic inflammatory disease (PID) (OR = 11.2), trichomoniasis (OR = 20.6), and vulvar dysplasia (OR = l5.7) but no risk associated with human papillomavirus (HPV), ASCUS, cervical dysplasia, genital warts, chlamydia, genital herpes or gonorrhea. Genital symptoms reported significantly more often with VVS included vulvar burning (91 vs. 12%), dyspareunia (81 vs. 15%), vulvar itching (68 vs. 23%) and dysuria (54 vs. 19%) (p < 0.0001). CONCLUSION: A history of genital infections is associated with an increased risk of VVS. Long-term follow-up case-control studies are needed to elucidate etiologic mechanisms, methods for prevention and effective treatment. PMID:12648313

    When vulvar lichen sclerosus occurs in prepubertal children it is widely believed that it is likely to remit at puberty. However when it occurs in adult women it is accepted that remission is unlikely and that in addition untreated or inadequately treated disease may be complicated by significant disturbance of vulvar architecture and less commonly squamous cell carcinoma. Our database reveals 18 girls who developed lichen sclerosus prior to puberty who are now adolescents or young adults. Twelve have remained under surveillance and the other six patients have been lost to follow-up. We report a prospective series of these 12 patients. Three patients have achieved complete remission sustained for three or more years, all prior to menarche. Nine patients, or 75% of the cohort, who still had active lichen sclerosus at puberty continue to require maintenance therapy after menarche. Of the 12, six have had significant disturbance of vulvar architecture. The concept that prepubertal lichen sclerosus resolves at puberty would appear not to be true in the majority of patients. Even when diagnosed early and treated effectively, childhood onset lichen sclerosus may be complicated by distortion of vulvar architecture. PMID:20199450

    Objective: The objectives of this study were to assess the efficacy of medical management for vulvar vestibulitis and to examine several historical variables and determine their predictive values as to which treatments will be most successful. Methods: Seventy-four patients diagnosed with vulvar vestibulitis were evaluated. Each patient was treated using a sequence of consecutive medical therapies for vulvar vestibulitis. These therapies were topical aqueous 4% lidocaine with intercourse, topical corticosteroid therapy, oral amitriptyline, topical low-dose 5-fluorouracil (5-FU) cream, intralesional alpha-interferon, and a low-oxalate diet in combination with oral calcium citrate. The patients were followed over 3–30 months and their responses to therapy were assessed. In addition, a statistical analysis was performed to determine the positive predictive values of certain historical variables and specific treatment successes. Results: Forty-nine patients reported positive responses to one of the initiated therapies. More specifically, 18.1% of the patients who used lidocaine, 33.8% who used topical corticosteroids, 57.1% who used amitriptyline, 16.7% who used 5-FU, none who received interferon, and 50% who tried a low-oxalate diet had positive responses to therapy. No historical variables were predictive of which therapies would have the most successful outcome. Conclusions: Medical management is effective in alleviating the symptoms of vulvar vestibulitis. Various aspects of a patient's history are not helpful in selecting the therapy that will be most effective. PMID:18472890

    Experimental modeling of inflammatory edema by sub-plantar injection of carrageenan and formalin in mice and rats is widely used to evaluate potential anti-inflammatory activity of new drugs. This systematic analysis of published data showed that carrageenan induced paw edema model is used for evaluating the anti-inflammatory activity mostly in rats rather than mice. Formalin induced paw edema in rats and mice is used primarily for evaluation of the analgesic activity of drugs. Taken together, the results of this systematic review of available literature on edema modeling substantiate recommendation to use carrageenan paw edema in rats and formalin paw edema in mice as complementary, but not interchangeable models of inflammation.

    OBJECTIVE To present a case of a patient with clinical and radiological features of reexpansion pulmonary edema, a rare and potentially fatal disease. CASE DESCRIPTION An 11-year-old boy presenting fever, clinical signs and radiological features of large pleural effusion initially treated as a parapneumonic process. Due to clinical deterioration he underwent tube thoracostomy, with evacuation of 3,000 mL of fluid; he shortly presented acute respiratory insufficiency and needed mechanical ventilation. He had an atypical evolution (extubated twice with no satisfactory response). Computerized tomography findings matched those of reexpansion edema. He recovered satisfactorily after intensive care, and pleural tuberculosis was diagnosed afterwards. COMMENTS Despite its rareness in the pediatric population (only five case reports gathered), the knowledge of this pathology and its prevention is very important, due to high mortality rates. It is recommended, among other measures, slow evacuation of the pleural effusion, not removing more than 1,500 mL of fluid at once. PMID:24142327

    Cerebral edema causes intracranial hypertension (ICH) which leads to severe outcome of patients in the clinical setting. Effective anti-edema therapy may significantly decrease the mortality in a variety of neurological conditions. At present drug treatment is a cornerstone in the management of cerebral edema. Osmotherapy has been the mainstay of pharmacologic therapy. Mannitol and hypertonic saline (HS) are the most commonly used osmotic agents. The relative safety and efficacy of HS and mannitol in the treatment of cerebral edema and reduction of enhanced ICP have been demonstrated in the past decades. Apart from its osmotic force, HS exerts anti-edema effects partly through inhibition of Na(+)-K(+)-2Cl(-) Cotransporter-1 (NKCC1) and aquaporin 4 (AQP4) expression in astrocytes. Melatonin may also reduce brain edema and exert neuroprotective effect on several central nervous system diseases through inhibition of inflammatory response. The inhibitors of Na/H exchanger, NKCC and AQP4 may attenuate brain edema formation through inhibition of excessive transportation of ion and water from blood into the cerebral tissue. In this review we survey some of the most recent findings in the drug treatment of brain edema focusing on the use of osmotherapy, melatonin and inhibitors of ion cotransporters and water channels. A better understanding of the molecular mechanism of these agents would help to improve in the clinical management of patients with brain edema. PMID:26948324

    2014-01-01

    Background Despite global eradication efforts, female genital cutting is still deep routed practice in some parts of Asia and East Africa. The crude and unscientific natures of the practice lead to many complications. Epidermoid inclusion cysts of the vulva are one of the late complications of female genital cutting and typically present as painless cystic swellings. But clinical presentation as ‘stone’ containing, hard vulvar mass is reported only once in the literature and presentation with acute vulvar pain has never been documented. Case presentation A 21 yrs old, Ethiopian, unmarried, lady presented with sever acute vulvar pain, discharge, and a stony hard vulvar swelling 13 years after type-III female genital cutting (infibulation). Surgical excision of the cyst, which contained two ‘stones’ inside it, and defibulation were done. Histopathology confirmed calcified, keratinizing epidermoid inclusion cyst of the vulva. Conclusions Clinicians, in areas where female genital cutting is prevalent, should be aware of such unusual late vulvar complication of the practice which might be misdiagnosed for other solid vulvar swellings and be familiar with the appropriate management.

    Vulvar dystrophy” is characterized by chronic alterations of vulvar trophism, occurring in both physiological (menopause) and pathological (lichen sclerosus, vulvar graft-versus-host disease) conditions. Associated symptoms are itching, burning, dyspareunia and vaginal dryness. Current treatments often do not imply a complete remission of symptoms. Adipose-Derived Stem Cells (ADSCs) injection represents a valid alternative therapy to enhance trophism and tone of dystrophic tissues. We evaluated efficacy of ADSCs-based therapy in the dystrophic areas. From February to April 2013 we enrolled 8 patients with vulvar dystrophy. A biopsy specimen was performed before and after treatment. Digital photographs were taken at baseline and during the follow-up. Pain was detected with Visual Analogue Scale and sexual function was evaluated with Female Sexual Function Index. All patients received 2 treatments in 3 months. Follow-up was at 1 week , 1 and 3 months, and 1 and 2 years. We obtained a significant vulvar trophism enhancement in all patients, who reported pain reduction and sexual function improvement. Objective exam with speculum was easy to perform after treatment. We believe ADSCs-based therapy finds its application in the treatment of vulvar dystrophies, since ADSCs could induce increased vascularization due to their angiogenic properties and tissue trophism improvement thanks to their eutrophic effect.

    Purpose The aim of the study was to report our experience with high-dose-rate interstitial brachytherapy (HDR-ISBT) in locally advanced and recurrent vulvar cancer. Material and methods Between 2004 and 2014, fourteen women with locally advanced or recurrent vulvar cancer were treated using HDR-ISBT in our Centre. High-dose-rate interstitial brachytherapy was performed as a separate treatment or in combination with external beam radiotherapy (EBRT) (given prior to brachytherapy). Results Patients were divided into: group I (n = 6) with locally advanced tumors, stages III-IVA after an incisional biopsy only, and group II (n = 8) with recurrent vulvar cancer after previous radical surgery. In group I, median follow up was 12 months (range 7-18 months); 1-year overall survival (OS) was 83%. Transient arrest of cancer growth or tumor regression was noticed in all patients but 4/6 developed relapse. Median time to failure was 6.3 months (range 3-11 months). The 1-year progression-free survival (PFS) was 33%. In group II, median follow up was 28 months (range 13-90 months). The 1-year and 3-year OS was 100% and 80%, respectively. The arrest of cancer growth or tumor regression was achieved in all patients. In 4/8 patients neither clinical nor histological symptoms of relapse were observed but 4/8 women experienced relapse. Median time to failure was 31 months (range 13-76 months). The 1-year and 3-year PFS was 100% and 62.5%, respectively. Two patients (14.3%) in group II had severe late toxicity (G3). Conclusions High-dose-rate interstitial brachytherapy is a well-tolerated treatment option in selected patients with advanced or recurrent vulvar cancer. It is a safe and effective treatment modality for advanced and recurrent vulvar cancer, yielding good local control with acceptable late treatment related side effects. In our study, patients with recurrent vulvar cancer had better results in HDR-ISBT treatment, probably because of the smaller tumor volume. This

    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. PMID:26080256

    A 61-year-old woman was referred to surgery for incidentally found colonic polyps during a health examination. Physical examination revealed widespread eczematous skin lesion without pruritus in the perianal and vulvar area. Abdominopelvic computed tomography showed an approximately 4-cm-sized, soft tissue lesion in the right perianal area. Inguinal lymph node dissection and Mils’ operation extended to perianal and perivulvar skin was performed. Histologically, the anal canal lesion was composed of mucin-containing signet ring cells, which were similar to those found in Pagetoid skin lesions. It was diagnosed as an anal canal signet ring cell carcinoma (SRCC) with perianal and vulvar Pagetoid spread and bilateral inguinal lymph node metastasis. Anal canal SRCC is rare, and the current case is the third reported case in the English literature. Seven additional cases were retrieved from the world literature. Here, we describe this rare case of anal canal SRCC with perianal Pagetoid spread and provide a literature review. PMID:26447133

    Women with vulvar vestibulitis syndrome (VVS) have a distinct burning pain provoked by almost any stimuli in the area around the vaginal introitus. In a previous study we observed an increased number of intraepithelial free nerve endings in women with VVS. The aim of the present study was to neurochemically characterize the superficial nerves in the vulvar vestibular mucosa of women with VVS. Immunohistochemical methods were used to detect neuropeptides normally found in various types of nerve fibers. Calcitonin gene-related peptide, which is known to exist in nociceptive afferent nerves, was the only neuropeptide detected in the superficial nerves of the vestibular mucosa. These findings confirm our previous theory that the free nerve endings within the epithelium are nociceptors. PMID:10592432

    Objective This study aimed to examine the prognostic value of overexpressed p16INK4a in vulvar cancer. Although the tumor suppressor p16INK4a has been shown to be of prognostic value in a wide variety of cancers and precancerous lesions, its role in the vulvar cancer is still unclear. Methods All publications in English language on the association between p16INK4a and clinicopathological features of vulvar cancer were searched from Pubmed, Embase, and Web of Science, and those in Chinese language were identified manually and online from the China National Knowledge Infrastructure. Strict inclusion and exclusion criteria were followed. Odds ratios(ORs) or risk ratios(RRs) with 95% confidence intervals(CIs) were pooled to assess the strength of association. Publication bias was estimated using funnel plots and the Egger’s regression test. Results A total of 17 studies with 2309 patients were included. The p16INK4a overexpression was found to correlate significantly with the lower International Federation of Gynecology and Obstetrics stage(I+II vs III+IV; OR = 0.60,95%CI:0.41–0.86,P = 0.006),negative lymph node metastasis(negative vs positive; OR = 0.61,95%CI:0.39–0.95,P = 0.029),patient’s age<55(OR = 0.54,95%CI:0.31–0.96,P = 0.034),human papillomavirus–positive status(OR = 0.01,95%CI:0.00–0.11,P<0.001),and higher overall survival(RR = 0.53,95%CI = 0.35–0.80,P = 0.003). Conclusion The p16INK4a might be associated with a higher survival and indicates better prognosis of vulvar cancer. PMID:27031618

    Objective The goal of this study was to investigate the between cluster of differentiation 109 (CD109) expression and tumor diameter, invasion depth, tumor grade, presence of lymph-node metastasis, and overall survival in patients with vulvar squamous cell carcinoma, which is the most common type of vulvar cancer. Method Twenty-six patients who underwent an operation for vulvar cancer between 1999 and 2009 in our clinic were included in this study. Immunohistochemical staining was performed on formalin-fixed and paraffin-embedded tissue. Result Tumor diameter was not found to be significantly associated with CD109 expression, intensity of cytoplasmic staining, or combined score (P = 0.325, P = 0.169, P = 0.352, respectively). Invasion depth and combined score were also not significantly correlated with CD109 expression (P = 0.324 and P = 0.174 respectively). There was a negative correlation between invasion depth and the intensity of cytoplasmic staining (P = 0.042). There was no significant correlation between tumor stage and CD109 expression, the intensity of cytoplasmic staining, and the combined score (P = 0.574, P = 0.389, P = 0.605, respectively). A significant positive correlation was observed between tumor grade and CD109 expression, the intensity of cytoplasmic staining, and the combined score (P = 0.003, P = 0.018, P = 0.008, respectively). No significant difference was found between the percentages of CD109 expression in patients with positive (48%) and negative (11%) lymph nodes (P = 0.058). The percentage of CD109 expression did not significantly differ in relation to overall survival (P = 0.483). Conclusion Comprehensive and more extensive studies are needed to examine the relationship between CD109 expression and vulvar malignant lesions. PMID:23776335

    Vulvar cancer is an uncommon disease with approximately 1000 cases reported annually in the UK. Lymph node involvement is an important prognostic indicator. Vulvectomy and bilateral groin node dissection are the preferred surgical treatments for early disease and increase survival. However, significant morbidity with lymphocyst formation and wound breakdown has been reported in more than 50% of cases. We report the first case following use of the PlasmaJet® neutral argon coagulation system to reduce postoperative lymphocyst formation. PMID:21792333

    Lichen sclerosus (LS) is an inflammatory dermatosis with a predilection for the anogential skin. Vulvar LS can be a debilitating disease, causing pruritus and pain, and it carries the potential for atrophy, scarring, and significant functional impairment. Recently, many advances have been made regarding the etiology and natural history of the disease process; however, much debate still exists regarding the most advantageous medical and surgical management of this disorder. In an effort to provide a comprehensive review on current vulvar LS literature, the following three controversies will be discussed: (1) optimal disease treatment, (2) theories behind LS's oncogenicity and treatments for minimizing malignancy, and (3) the value of surgical treatment for LS. Ultra-potent topical corticosteroids (TCSs) are the first-line treatment for vulvar LS, while topical calcineurin inhibitors (TCIs) remain second-line agents for patients for whom TCS treatment resulted in incomplete resolution of symptoms or adverse events. Due to the relapsing nature of the disease, long-term maintenance therapy is often required. In addition, recent advances have contributed to the understanding of the association between LS and squamous cell carcinoma (SCC). While the exact mechanism responsible for LS-associated SCC is not known, immune dysregulation and inflammation may play an important role; therefore, successful treatment of LS should be directed towards alleviation of symptoms and reversal of the underlying histopathologic changes. Patients with LS-associated malignancy, as well as patients who need correction of functionally restrictive, scarring processes, can successfully undergo surgical intervention with tissue conservation.

    This review provides guidelines and aims to estimate utilisation rates of treatment modalities applied in vulvar cancer. Current standards of treatment are as follows: wide local excision instead of radical vulvectomy in the case of small tumour (T < 2 cm), no lymph node dissection in the case of a micro-invasive tumour (invasion <1 mm), unilateral lymph node dissection in the case of a lateral tumour and inguinal-femoral lymphadenectomy by separate incisions instead of en bloc inguinal-femoral lymph node excision. Implementation of sentinel lymph node biopsy in patients with tumours not exceeding 4 cm is safe and efficiently eliminates redundant groin dissections. Pre-operative treatment with chemoradiotherapy reduces tumour size and improves surgical excision of inoperable primary tumours or fixed lymph nodes, but side effects are considerable. Literature search performed using PubMed database (from: 1 June 2005 to 1 June 2015) with the terms 'consecutive', 'vulvar cancer', 'treatment' identified seven full-text manuscripts, including data on 1114 patients. Utilisation rates of neoadjuvant radiochemotherapy, chemotherapy alone, surgery, adjuvant radiotherapy and adjuvant radiochemotherapy were 5.9%, 0.3%, 89.3%, 22.6% and 0.2% respectively. An evidence-based estimation of appropriate rates of surgery, radiotherapy and chemotherapy for vulvar cancer is needed to compare management reflecting guidelines with presented here real frequency of applied modalities.

    Vulvar cancer is a relatively rare gynecologic malignancy with an annual incidence in developed countries of approximately 2 per 100,000 women. Vulvar squamous cell carcinoma (VSCC) has two etiological pathways: a high risk human papillomavirus (HPV)-dependent route, which has usual vulvar intraepithelial neoplasia (uVIN) as a precursor lesion, and an HPV-independent route, which is associated with differentiated VIN (dVIN), lichen sclerosus, and genetic alterations, such as TP53 mutations. Research on the molecular etiology of vulvar cancer has increased in the past years, not only regarding genetic alterations, but also epigenetic changes. In genetic alterations, a mutation irreversibly changes the nucleotide sequence of the DNA, or the number of copies of chromosomes per cell is altered. In epigenetics, the nucleotide sequence remains the same but genes can be 'switched' on or off by, for example, DNA methylation or histone modification. We searched the current literature on genetic and epigenetic alterations in VSCC and its precursor lesions. Many studies have reported a higher incidence of somatic mutations in HPV-negative tumors compared to HPV-positive tumors, with TP53 mutations being the most frequent. Allelic imbalances or loss of heterozygosity are more frequently found in higher stages of dysplasia and in invasive carcinomas, but it is not exclusive to HPV-negative tumors. A limited number of studies are available on epigenetic changes in vulvar lesions, with hypermethylation of CDKN2A being the most frequently investigated change. For most genes, hypermethylation occurs more frequently in vulvar squamous cell carcinomas than in precursor lesions. As most studies have focused on HPV infection and TP53 mutations, we suggest that more research should be performed using whole genome or next generation sequencing to determine the true landscape of genetic and epigenetic alterations in vulvar squamous cell carcinoma.

    Vulvar melanoma is the second most common vulvar cancer. Patients with vulvar melanoma usually present with the disease at a late stage and have a poor prognosis. The prognostic predictors reported in the literature are not unequivocal and the role of lichen sclerosus and c-KIT mutations in the aetiology of vulvar melanoma is unclear. Breslow staging currently seems to be the most adequate predictor of prognosis. We thus performed a clinicopathological and literature review to identify suitable predictors of prognosis and survival and investigated the expression of c-KIT (by immunohistochemistry) in patients with vulvar melanoma (n=33) from the Gynaecological Cancer Centres of the Royal Hospital for Women (Sydney, Australia) and John Hunter Hospital (Newcastle, Australia). Our series of 33 patients fitted the expected clinical profile of older women: delayed presentation, high stage, limited response to treatment and poor prognosis. We identified 3 patients (9.1%) with lichen sclerosus associated with melanoma in situ, although no lichen sclerosus was found in the areas of invasive melanoma. No patient had vulvar nevi. We identified a) Breslow's depth, b) an absence of any of the pathological risk factors, such as satellitosis, in-transit metastasis, lymphovascular space invasion (LVSI) and dermal mitosis, c) removal of inguino-femoral lymph nodes, d) lateral margin of >1 cm, and e) c-KIT expression as valuable prognostic predictors for disease-free survival. We conclude that c-KIT expression is, apart from Breslow's depth, another valuable predictor of prognosis and survival. Lichen sclerosus may be associated with vulvar melanoma. PMID:24535703

    The objective of this study was to assess reduction in cerebral edema following linear accelerator radiosurgery (LINAC) as first line therapy for brain metastasis. We reviewed the medical records of all patients who underwent LINAC radiosurgery for brain metastasis at our institution during 2010-2012, and who had not previously undergone either surgery or whole brain radiotherapy. Data were analyzed for 55 brain metastases from 46 patients (24 males), mean age 59.9 years. During the 2 months following LINAC radiosurgery, the mean steroid dose decreased from 4.8 to 2.6 mg/day, the mean metastasis volume decreased from 3.79±4.12 cc to 2.8±4.48 cc (p=0.001), and the mean edema volume decreased from 16.91±30.15 cc to 12.85±24.47 cc (p=0.23). The 17 patients with reductions of more than 50% in brain edema volume had single metastases. Edema volume in the nine patients with two brain metastases remained stable in five patients (volume change <10%, 0-2 cc) and increased in four patients (by >10%, 2-14 cc). In a subanalysis of eight metastases with baseline edema volume greater than 40 cc, edema volume decreased from 77.27±37.21 cc to 24.84±35.6 cc (p=0.034). Reductions in brain edema were greater in metastases for which non-small-cell lung carcinoma and breast cancers were the primary diseases. Overall, symptoms improved in most patients. No patients who were without symptoms or who had no signs of increased intracranial pressure at baseline developed signs of intracranial pressure following LINAC radiosurgery. In this series, LINAC stereotactic radiosurgery for metastatic brain lesions resulted in early reduction in brain edema volume in single metastasis patients and those with large edema volumes, and reduced the need for steroids.

    Melatonin has been shown to diminish edema in rats. Melatonin can be used to treat spinal cord injury. This study presumed that melatonin could relieve spinal cord edema and examined how it might act. Our experiments found that melatonin (100 mg/kg, i.p.) could reduce the water content of the spinal cord, and suppress the expression of aquaporin-4 and glial fibrillary acidic protein after spinal cord injury. This suggests that the mechanism by which melatonin alleviates the damage to the spinal cord by edema might be related to the expression of aquaporin-4 and glial fibrillary acidic protein.

    There have been two major theories surrounding the development of edema in nephrotic syndrome (NS), namely, the under- and overfill hypotheses. Edema is one of the cardinal features of NS and remains one of the principal reasons for admission of children to the hospital. Recently, the discovery that proteases in the glomerular filtrate of patients with NS are activating the epithelial sodium channel (ENaC), resulting in intrarenal salt retention and thereby contributing to edema, might suggest that targeting ENaC with amiloride might be a suitable strategy to manage the edema of NS. Other potential agents, particularly urearetics and aquaretics, might also prove useful in NS. Recent evidence also suggests that there may be other areas involved in salt storage, especially the skin, and it will be intriguing to study the implications of this in NS. PMID:26290369

    This study describes a patient diagnosed as a case of bipolar affective disorder complaining of bothersome incidence of pedal edema 1 month after the initiation of atypical antipsychotic regimen with risperidone and quetiapine. All hematological and biochemical profiles were found to be normal. On discontinuation of risperidone, the condition remained unresolved even after 2 weeks, and the edema progressed reaching her calves. On tapering the dose of quetiapine, she started showing gradual improvement in edematous condition. Quetiapine was slowly discontinued. No further recurrence of edema occurred, and hence, no further medication changes were implemented. Pedal edema was found to be resolved within weeks of dechallenge of the regimen. Naranjo adverse drug reaction probability scale gave a score of 7 which denotes “probable” adverse drug reaction with quetiapine. PMID:26997731

    Purpose To report transient corneal edema after phacoemulsification as a predictive factor for the development of pseudophakic cystoid macular edema (PCME). Methods A total of 150 eyes from 150 patients (59 men and 91 women; mean age, 68.0 ± 10.15 years) were analyzed using spectral domain optical coherence tomography 1 week and 5 weeks after routine phacoemulsification cataract surgery. Transient corneal edema detected 1 week after surgery was analyzed to reveal any significant relationship with the development of PCME 5 weeks after surgery. Results Transient corneal edema developed in 17 (11.3%) of 150 eyes 1 week after surgery. A history of diabetes mellitus was significantly associated with development of transient corneal edema (odds ratio [OR], 4.04; 95% confidence interval [CI], 1.41 to 11.54; p = 0.011). Both diabetes mellitus and transient corneal edema were significantly associated with PCME development 5 weeks after surgery (OR, 4.58; 95% CI, 1.56 to 13.43; p = 0.007; and OR, 6.71; CI, 2.05 to 21.95; p = 0.003, respectively). In the 8 eyes with both diabetes mellitus and transient corneal edema, 4 (50%) developed PCME 5 weeks after surgery. Conclusions Transient corneal edema detected 1 week after routine cataract surgery is a predictive factor for development of PCME. Close postoperative observation and intervention is recommended in patients with transient corneal edema. PMID:25646056

    Cerebral edema is a potentially life-threatening complication shared by diseases of different etiology, such as diabetic ketoacidosis, acute liver failure, high altitude exposure, dialysis disequilibrium syndrome, and salicylate intoxication. Pulmonary edema is also habitually present in these disorders, indicating that the microcirculatory disturbance causing edema is not confined to the brain. Both cerebral and pulmonary subclinical edema may be detected before it becomes clinically evident. Available evidence suggests that tissue hypoxia or intracellular acidosis is a commonality occurring in all of these disorders. Tissue ischemia induces physiological compensatory mechanisms to ensure cell oxygenation and carbon dioxide removal from tissues, including hyperventilation, elevation of red blood cell 2,3-bisphosphoglycerate content, and capillary vasodilatation. Clinical, laboratory, and necropsy findings in these diseases confirm the occurrence of low plasma carbon dioxide partial pressure, increased erythrocyte 2,3-bisphosphoglycerate concentration, and capillary vasodilatation with increased vascular permeability in all of them. Baseline tissue hypoxia or intracellular acidosis induced by the disease may further deteriorate when tissue oxygen requirement is no longer matched to oxygen delivery resulting in massive capillary vasodilatation with increased vascular permeability and plasma fluid leakage into the interstitial compartment leading to edema affecting the brain, lung, and other organs. Causative factors involved in the progression from physiological adaptation to devastating clinical edema are not well known and may include uncontrolled disease, malfunctioning adaptive responses, or unknown factors. The role of carbon monoxide and local nitric oxide production influencing tissue oxygenation is unclear. PMID:22579570

    A 25-year-old Caucasian female with multiple genital warts involving the vulvar area was treated with imiquimod 5% cream. During follow-up the patient developed areas of hypopigmentation at the site of application of imiquimod cream and areas of hypomelanosis around multiple preexisting nevi of the trunk. At 18 months follow-up genital depigmentation persisted and halo nevi of the trunk were still present. Different mechanisms of imiquimod-induced depigmentation have been reported. Halo nevi are considered expression of an autoimmune response. In the case presented here, it might be conceivable that both vitiligo-like depigmentation at the site of application and halo of hypomelanosis around melanocytic nevi have been induced by the same immunologic mechanism elicited by topical application of imiquimod.

    Vulvar angiomyofibroblastoma is rare tumor of obscure histological origin. Here a case of 49-year old woman is described with this intriguing benign vulvar entity. The tumor developed at left vulvar labia and clinically imitated Bartholin cyst with clinical complaints of regional discomfort without pain. A macroscopic evaluation revealed well separated, encapsulated tumor of 3,5 cm in diameter. On cut surface the tumor was whitish, flesh, solid with myxoid appearance without any apparent cysts formation. There were alternating hypo- and hypercellular in the neoplasm. Microscopically the tumor comprised proliferation of small thin walled vessels that were surrounded with cuffs and islands of epithelioid, spindle and plasmacytoid cells with occasional vacuolization. Some aggregations of cells were quite dense and in such fields, vessels were compressed and ecstatic enough to mimic a bit haemangiopericytoma pattern. A production of myxoid intercellular matrix was seen in loose, hypocellular areas and was confirmed by positive pas-alcian blue stain that demonstrated prominent myxoid stroma and intracytoplasmatic globules of acid glicoproteins. The immunoprofile was remarkable enough to show strong expression of vimentin and desmin, while there was a lack of pan-keratin (CKAE1/3) and smooth muscle actin (SMA) immunoreactivities. Such an immunofentype is regarded to share some of myofibrolastic origin despite SMA negativity. Tumor cells seemed to sprout from perivascular regions giving an impression of accumulations strictly associated with neighbouring vascular branches. This configuration of cells is very often viewed as pericyte-like proliferation. Thus, our case of angiomyofibroblastoma is an example of tumor that probably derives from perivascular stem cells that acquire some of myoid features. PMID:25546934

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

    Neurogenic pulmonary edema is a rare and serious complication in patients with head injury. It also may develop after a variety of cerebral insults such as subarachnoid hemorrhage, brain tumors and after epileptic seizures. Thirty six patients with severe head injury and four patients with cerebrovascular insults treated in Intensive Care Unit of HC-UNICAMP from January to September 1995 were evaluated. In this period there were two patients with neurogenic pulmonary edema, one with head injury and other with intracerebral hemorrhage. Diagnosis was made by rapid onset of pulmonary edema, severe hypoxemia, decrease of pulmonary complacence and diffuse pulmonary infiltrations, without previous history of tracheal aspiration or any other risk factor for development of adult respiratory distress syndrome. In the first case, with severe head trauma, neurogenic pulmonary edema was diagnosed at admission one hour after trauma, associated with severe systemic inflammatory reaction, and good outcome in three days. The second case, with hemorrhagic vascular insult, developed neurogenic pulmonary edema the fourth day after drainage of intracerebral hematoma and died. PMID:9629392

    A 57-year-old man who had been intermittently taking one 300-mg tablet of quinine sulfate orally for leg cramps experienced transient acute pulmonary edema and hypotension 30-40 minutes after ingestion on two consecutive occasions. He was not taking any concomitant drugs, and there was no alternative explanation for either event. Serial troponin T tests and electrocardiograms, obtained on admission to the hospital, followed by an outpatient echocardiogram and a coronary angiogram, were essentially normal. We compared this case with one previously published and nine previously unpublished reports of quinine-associated pulmonary edema and conclude that some cases of pulmonary edema or adult respiratory distress syndrome in patients with malaria may be caused by an adverse reaction to quinine. Although infrequent, clinicians should be aware of this potentially serious and costly adverse reaction. PMID:15460183

    The treatment of diabetic macular edema is rapidly evolving. The era of laser therapy is being quickly replaced by an era of pharmacotherapy. Several pharmacotherapies have been recently developed for the treatment of retinal vascular diseases such as diabetic macular edema. Several intravitreal injections or sustained delivery devices have undergone phase 3 testing while others are currently being evaluated. The results of clinical trials have shown the superiority of some of these agents to laser therapy. However, with the availability of several of these newer agents, it may be difficult to individualize treatment options especially those patients respond differently to various therapies. As such, more effort is still needed in order to determine the best treatment regimen for a given patient. In this article, we briefly summarize the major new therapeutic additions for the treatment of diabetic macular edema and allude to some future promising therapies. PMID:24379924

    Retinal edema should be defined as any increase of water of the retinal tissue resulting in an increase in its volume. It may be of cytotoxic or vasogenic origin. Development of vasogenic macular edema is dependent on a series of factors such as blood pressure, blood-retinal barrier permeability, retinal cell damage, retinal tissue osmotic pressure and retinal tissue compliance. Objective measurements of retinal thickness are now possible using the Retinal Thickness Analyser. Localised measurements of blood-retinal barrier permeability may also be obtained using the Retinal Leakage Analyser, a modified confocal scanning laser fluorometer, while obtaining simultaneously angiographic images of the choroid and retina. These new imaging techniques show that cytotoxic and vasogenic retinal edema may occur independently in the early stages of diabetic retinopathy. These findings offer new perspectives for designing novel therapeutic strategies. PMID:10896349

    Gynaecological leiomyosarcoma (gLMS) represent a heterogeneous group of soft tissue sarcoma, characterized by rare incidence, high aggressiveness and propensity to infiltrate secondary organs, poor prognosis and lethality, because of the lack of biological mechanisms that underlying their progression and effective pharmaceutical treatments. This study was focused on some of the aspects of progression and dissemination of a subtype of gLMS namely vulvar LMS (vLMS). We therefore used a vulvar LMS-derived cell line namely SK-LMS-1, coupled with in vitro and in vivo assays. We observed that SK-LMS-1 cells have a strong invasive capacity in vitro, through the activity of matrix metalloproteinases 2 and 9, while in vivo these cells induce a strong angiogenic response and disseminate to the chick embryo liver. Therefore, we postulate that metalloproteinases are involved in the spreading behaviour of SK-LMS-1. Further investigations are necessary to better understand the molecular and cellular machinery involved in the progression of this malignancy. PMID:26010680

    We sought to determine whether women with in situ or invasive squamous cell vulvar cancer were more likely than other women to have had a previous or concurrent tumour at other anogenital sites. One hundred and fifty-eight women with vulvar cancer were identified who were first diagnosed during 1980-1985, were ages 18-79 years at that time, and were residents of one of three counties in western Washington. Two control groups were selected: (1) from records of hospital pathology departments, a sample of 113 women with certain benign conditions of the vulva; (2) through random digit dialing, a sample of 212 women from the general population of these counties. Information on a history of other cancers, and on sexual, reproductive, medical, and demographic characteristics was collected from cases and controls in at-home interviews. Cases were more likely to report a history of other anogenital cancers than were controls, with relative risks of 3.5-29.8, depending on the type of case group and type of control. These associations were not explained by case-control differences in demographic characteristics or frequency of cervical screening. On the other hand, prior or concurrent non-anogenital cancers were equally common in cases and controls. These results support the hypothesis that the different anogenital cancers have at least one aetiology in common. PMID:3390379

    Objective To assess the efficacy of topical capsaicin in the treatment of vulvar vestibulitis syndrome. Study Design Thirty-three consecutive women referred for vulvar vestibulitis syndrome were treated with topical capsaicin 0.05 %. The capsaicin cream was applied twice a day for 30 days, then once a Day for 30 days, and finally 2 times a week for 4 months. Results In 19 patients (59%), improvement of symptoms was recorded, but no complete remission was observed. Symptoms recurred in all patients after the use of capsaicin cream was discontinued. A return to a twice-weekly topical application of the cream resulted in the improvement of symptoms. Severe burning was reported as the only side effect by all the patients. Conclusion Response to treatment was only partial, possibly due to the concentration of the compound being too low, or to the need for more frequent than daily applications. The therapeutic role of capsaicin should hence be confined to a last-choice medical approach. PMID:15775875

    Vulvar lichen sclerosis (VLS) is a chronic, inflammatory and mucocutaneous disease of extragenital skin, which often goes undetected for years. The underlying causes are associated with the decrease of VEGF that reduces the blood oxygenation of vulva and the structural changes in the collagen fibrils, which can lead to scarring of the affected area. However, few methods are available for quantitative detection of VLS. Clinician's examinations are subjective and may lead to misdiagnosis. Spectroscopy is a potentially effective method for noninvasive detection of VLS. In this paper, we developed a polarized, hyperspectral imaging system for quantitative assessment. The system utilized a hyperspectral camera to collect the reflectance images of the entire vulva under Xenon lamp illumination with and without a polarizer in front of the fiber. One image (Ipar) acquired with the AOTF parallel to the polarization of illumination and the other image (Iper) acquired with the AOTF perpendicular to the illumination. This paper compares polarized images of VLS in a pilot clinical study. The collected reflectance data under Xenon lamp illumination without a polarizer are calibrated and the hyperspectral signals are extracted. An IRB approved clinical trial was carried out to evaluate the clinical utility for VLS detection. Our pilot study has demonstrated the technical potential of using this polarized hyperspectral imaging system for in vivo detection of vulvar lichen sclerosis.

    Numerous studies have revealed that cofilin-l (CFL1) is associated with cancer cell migration and invasion in various types of tumor tissues. We investigated the roles of CFL1 in vulvar squamous cell carcinoma (VSCC). CFL1 expression was detected in VSCC and normal vulvar tissues using immunohistochemistry and western blotting. The vulvar carcinoma SW962 cell line was transfected with CFL1 small interfering RNA (siRNA) and exposed to periplocoside. We then assessed changes in cell proliferation, apoptosis, invasion and metastasis. We detected changes in CFL1 mRNA and protein expression by RT-PCR and western blotting, and alterations in protein expression of various relevant molecules by western blotting. CFL1 expression was found to be significantly upregulated in the VSCC tissues compared with the normal vulvar tissues by immunohistochemistry and western blotting (P<0.05) and was positively correlated with International Federation of Gynecology and Obstetrics (FIGO) stage, differentiation and lymphatic metastasis (P<0.05). After CFL1 knockdown by siRNA transfection, SW962 cells exhibited a decrease in growth, G1 phase cell cycle arrest, induction of apoptotic, low invasion and metastasis, and disrupted lamellipodium formation. We found that the protein expression of Bcl-xL, cyclin A1, MMP2, MMP9 and STAT3 was decreased, while expression of Bax was increased. Periplocoside inhibited SW962 cell growth, promoted apoptosis, suppressed invasion and migration, and lamellipodium formation. Periplocoside exposure resulted in lower CFL1, Bcl-xL, cyclin A1, MMP2, MMP9 and STAT3 levels, but a higher Bax level compared with the control group. We demonstrated that abnormal CFL1 expression may affect vulvar carcinogenesis and subsequent progression. CFL1 silencing by siRNA significantly inhibited VSCC cell progression, which suggests that CFL1 is a potential therapeutic target for vulvar cancer.

    2015-01-01

    Purpose: To review the relationship between kinetics, efficacy, and safety of several corticosteroid formulations for the treatment of diabetic macular edema. Methods: Reports of corticosteroid use for the treatment of diabetic macular edema were identified by a literature search, which focused on the pharmacokinetics, efficacy, and safety of these agents in preclinical animal models and clinical trials. Results: Available corticosteroids for diabetic macular edema treatment include intravitreal triamcinolone acetonide, dexamethasone, and fluocinolone acetonide. Because of differences in solubility and bioavailability, various delivery mechanisms are used. Bioerodible delivery systems achieve higher maximum concentrations than nonbioerodible formulations. There is a relationship between visual gains and drug persistence in the intravitreal compartment. Safety effects were more complex; level of intravitreal triamcinolone acetonide exposure is related to development of elevated intraocular pressure and cataract; this does not seem to be the case for dexamethasone, where two different doses showed similar mean intraocular pressure and incidence of cataract surgery. With fluocinolone acetonide, rates of intraocular pressure elevations requiring surgery seem to be dose related; rates of cataract extraction were similar regardless of dose. Conclusion: Available corticosteroids for diabetic macular edema exhibit different pharmacokinetic profiles that impact efficacy and adverse events and should be taken into account when developing individualized treatment plans.

    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. PMID:24147200

    Little is known on the difference in the incidence of vulvar and vaginal melanomas in various racial/ethnic groups. Population-based incidence of these melanomas in Asian and Hispanic individuals is almost unknown. Using 1992-2005 data provided by the National Cancer Institute's Surveillance, Epidemiology, and End Results Program, we calculated age-adjusted incidence rates of vulvar and vaginal melanomas in various racial/ethnic groups. From 1992 to 2005, there were 324 vulvar melanomas and 125 vaginal melanomas diagnosed in this group. The annual age-adjusted incidence rates (per million female population) of vulvar and vaginal melanomas in the different racial/ethnic groups was 0.87 (Blacks), 0.75 (American-Indian), 1.03 (Asians and Pacific Islanders), 1.22 (Hispanics), and 1.90 (non-Hispanic Whites). The overall white/black incidence ratio in vulvar and vaginal melanomas was 3.14 : 1 and 1.02 : 1, respectively; which is much less than that of cutaneous melanoma (13 : 1-17 : 1) and uveal melanoma (18 : 1) and is similar to that of conjunctival melanoma (2.6 : 1) and other mucosal melanomas (2.1 : 1-2.3 : 1). The low racial difference in vulvar and vaginal melanomas (as well as conjunctival and other mucosal melanomas) may be determined by their microenvironment factors (all originate from mucosa or semi-mucosa tissues). The incidence of vulvar and vaginal melanomas has does not increased in recent decades or toward the south (more sun exposure), indicating that ultraviolet radiation is not a causative factor in these melanomas. The slight decrease of incidence of vulvar melanoma in dark pigmented individuals may be related to the biochemical protective effects of melanin (as an antioxidant) rather than their photo-screen effects.

    We report a case of unusual cutaneous amyloidosis involving the vulva in a patient with multiple myeloma. Genital examination revealed a dense agglomeration of verrucous papules and pedunculated condyloma-like tumors. The correct diagnosis was established by immunohistochemical examinations that visualized large amounts of lambda light chains, whereas no reaction was detected for kappa light chains or human papilloma virus. In this way, the differential diagnosis of condylomata acuminata could be ruled out. Condyloma-like lesions have been described in patients suffering from multiple myeloma, but the present case is unusual because of the extensive involvement. Vulvar amyloidosis should be added to the list of possible presentations of myeloma-associated systemic amyloidoses. PMID:9920983

    Malignant melanoma of the urethra is a rare tumour that is difficult to diagnose and treat, resulting in a poor prognosis. In this paper, we present the case of a 65-year-old woman who was referred to a gynaecologist because of a urethral mass that mimicked a caruncle. The tumour was removed by local excision, and a pathological analysis revealed a malignant melanoma. Distal urethrectomy was performed after three months with no evidence of residual tumour. There was no evidence of disease at a six-year followup. In this paper, we compare the epidemiology, treatment, staging, and prognosis of vulvar cancer in general to malignant melanoma of the vulva in particular. PMID:23320214

    Vulvar lichen sclerosus (VLS) is a chronic inflammatory disease with a huge impact on a person's quality of life. On the basis of the immunologic changes in VLS, treatment with a high potency topical corticosteroid is recommended. The currently available guidelines identified the ultra-potent corticosteroid clobetasol propionate 0.05% (CP) as the first-line recommended treatment but growing evidence supports the use of the potent corticosteroid mometasone furoate 0.1% (MMF). We reviewed the available studies assessing MMF in the treatment of VLS. Both non comparative and comparative studies were included in this review. Findings from clinical trials indicate that MMF is an effective and safe option in the treatment of VLS both in the active phase and in long-term maintenance treatment. Consistent with the findings from the comparative studies, MMF shows similar efficacy and safety to CP. PMID:25449823

    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.

    Influenza infection can cause acute respiratory distress syndrome (ARDS), leading to poor disease outcome with high mortality. One of the driving features in the pathogenesis of ARDS is the accumulation of fluid in the alveoli, which causes severe pulmonary edema and impaired oxygen uptake. In this issue of the JCI, Peteranderl and colleagues define a paracrine communication between macrophages and type II alveolar epithelial cells during influenza infection where IFNα induces macrophage secretion of TRAIL that causes endocytosis of Na,K-ATPase by the alveolar epithelium. This reduction of Na,K-ATPase expression decreases alveolar fluid clearance, which in turn leads to pulmonary edema. Inhibition of the TRAIL signaling pathway has been shown to improve lung injury after influenza infection, and future studies will be needed to determine if blocking this pathway is a viable option in the treatment of ARDS.

    The evolution of scuba divers pulmonary edema is described. When discovered in 1981, it was believed to be a cold-induced response in a submerged, otherwise healthy, scuba diver. The clinical features are described and discussed, as are the demographics. An alleged prevalence of 1.1% was complicated by problematic statistics and an apparent increase in reported cases. Recurrences both while diving and swimming or snorkeling were common. More recent case reports and surveys are described, identifying predisposing factors and associations, including cardiac pathology. Stress cardiomyopathies, reversible myocardial disorder or Takotsubo cardiomyopathy, may complicate the presentation, especially in older females. Relevant cardiac investigations and autopsy findings are reviewed. Disease severity and potential lethality of scuba divers pulmonary edema became more apparent early this century, and these influence our current recommendations to survivors. First aid and treatment are also discussed. PMID:27265985

    Objective To systematically review previous studies and to evaluate the feasibility and safety of video endoscopic inguinal lymphadenectomy (VEIL) in vulvar cancer. Methods We conducted a comprehensive review of studies published through September 2014 to retrieve all relevant articles. The PubMed, EMBASE, Web of Science, Cochrane Library, Wan Fang Data and Chinese National Knowledge Infrastructure databases were systematically searched for all relevant studies published in English or Chinese through September 2014. Data were abstracted independently by two reviewers, and any differences were resolved by consensus. Results A total of 9 studies containing 249 VEIL procedures involving 138 patients were reviewed. Of the 249 VEIL procedures, only 1 (0.4%) was converted to an open procedure for suturing because of injury to the femoral vein. The range of operative time was 62 to 110 minutes, and the range of estimated blood loss was 5.5 to 22 ml. The range of the number of harvested lymph nodes was 7.3 to 16. The length of hospital stay varied from 7 to 13.6 days across reports. The incidence of lymph node metastasis was 19.7% (27/138), and the recurrence rate was 4.3% (3/70) within 3 to 41 months of follow-up. One or more short-term complications were documented in 18 of 138 (13.0%) patients. Complications after VEIL were observed in 14 (10.13%) patients and in 15 (6.0%) of the VEIL cases, including major lymphocyst formation in 9 (3.6%), lymphorrhea in 2 (0.8%), inguinal wound infection without wound breakdown in 3 (1.2%) and lymphedema in 1 (0.4%). Conclusions VEIL appears to be a feasible procedure in the management of vulvar cancer. There may be potential benefits that result in lower morbidity compared to traditional methods, but this has yet to be objectively proven. PMID:26496391

    Every year thousands of ski, trekking or climbing fans travel to the mountains where they stay at the altitude of more than 2500-3000m above sea level or climb mountain peaks, often exceeding 7000-8000m. High mountain climbers are at a serious risk from the effects of adverse environmental conditions prevailing at higher elevations. They may experience health problems resulting from hypotension, hypoxia or exposure to low temperatures; the severity of those conditions is largely dependent on elevation, time of exposure as well as the rate of ascent and descent. A disease which poses a direct threat to the lives of mountain climbers is high altitude pulmonary edema (HAPE). It is a non-cardiogenic pulmonary edema which typically occurs in rapidly climbing unacclimatized lowlanders usually within 2-4 days of ascent above 2500-3000m. It is the most common cause of death resulting from the exposure to high altitude. The risk of HAPE rises with increased altitude and faster ascent. HAPE incidence ranges from an estimated 0.01% to 15.5%. Climbers with a previous history of HAPE, who ascent rapidly above 4500m have a 60% chance of illness recurrence. The aim of this article was to present the relevant details concerning epidemiology, pathophysiology, clinical symptoms, prevention, and treatment of high altitude pulmonary edema among climbers in the mountain environment.

    Malignant melanoma of the vulva is a rare disease with aggressive behavior and poor prognosis. It consist < 5% of all cases of melanoma in females, as the ratio of its manifestation, compared with the cutaneous melanoma is 1:71. Higher risk of developing melanoma of the vulva is established in white women, as the peak of the incidence is between 60 and 70 years of age. Clinically, MM of the vulva manifests as asymptomatic pigmented, rarely a pigmented lesion, as the usual clinical form is superficial spreading MM and much less common nodular MM, which is associated with a poorer prognosis in. general. The diagnosis is confirmed by histological examination. Conduction of PCR and DNA analysis for detection of BRAF mutations, NRAS mutations and KIT amplification is also appropriate. Advanced age, black race, tumor size, tumor thickness, ulceration, presence of satellite lesions, involvement of adjacent organs (vagina, urethra), and the presence of regional or distant metastases are identified as the most important prognostic markers. Radical wide excision followed by bilateral lymphadenectomy id considered as the optimal therapeutic approach. PMID:25909143

    Vaginal and vulvar cancers do not account for a large proportion of gynecologic malignancies but their impact is significant. Both vaginal and vulvar lesions have precursors and display levels of dysplasia before progression to invasive disease. Human Papillomavirus (HPV) is a known causative agent of such dysplasia and can be detected now more readily than ever with adequate recognition techniques and provider awareness. Although HPV vaccination is still lagging compared to other recommended childhood vaccinations, the impact on lower genital tract neoplasia is promising. The bivalent and quadrivalent vaccines have been shown to be efficacious and the newest nonavalent vaccine should add even more of impact on coverage of cancer-causing HPV types. Although it is still early to show true clinical and population-based disease reduction due to low disease incidence and relatively short time of vaccine availability, the potential is noteworthy.

    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.

    Ospemifene is a selective estrogen receptor modulator (SERM), or estrogen receptor agonist/antagonist, that was recently approved by the US Food and Drug Administration for the treatment of dyspareunia associated with vulvar and vaginal atrophy, a chronic condition that affects up to 60% of postmenopausal women. Ospemifene is the first and only nonestrogen compound approved for this indication. Compared with other approved SERMs, such as tamoxifen, toremifene, bazedoxifene, and raloxifene, the estrogen-like effects of ospemifene in the vaginal epithelium are unique. This review first discusses the rationale for developing ospemifene, including its mechanism of action, and then focuses on the clinical development of ospemifene for the treatment of dyspareunia associated with vulvar and vaginal atrophy. Included are discussions of the effects of ospemifene on the endometrium, serum lipids, coagulation markers, bone, and breast cancer. In conclusion, ospemifene is a SERM with a unique estrogen agonist/antagonist tissue profile that was recently approved in the US for the treatment of dyspareunia associated with vulvar and vaginal atrophy in postmenopausal women. Ospemifene warrants further clinical investigation for the treatment and prevention of osteoporosis and breast cancer. PMID:24109197

    Background Upper extremity lymph edema is the most common side effect of breast cancer treatment that may produce significant physical and psychological morbidity. Pain is the frequent symptom of lymph edema that causes impairment of activities in daily life. Objectives The aim of this study was assessment of the effect of complex decongestive therapy (CDT) on upper extremity lymph edema and pain in women with post breast surgery lymph edema. Patients and Methods In this quasi- experimental research with before- after design, 36 women with moderate lymph edema after breast surgery participated in the program. Edema volume was measured by water displacement method; pain values were evaluated by visual analog scale (VAS). Data were recorded before intervention and 2 and 4 weeks after it. CDT included the first phase (intensive phase) and the second phase (maintenance phase). Each phase lasted 2 weeks. After use of Shapiro Wilk test for normality, analysis of variances with GEE and repeated measurements were used to analyze the data. Results After one month doing CDT program, significant decrease of edema was noticed (P < 0.0001), also pain decreased during 2 and 4 weeks after intervention (P < 0.0001). Conclusions This study indicated that CDT program is effective in reducing lymph edema volume and pain in women with moderate post breast surgery lymph edema. It seems that raising patients’ awareness and training healthcare professionals regarding lymph edema preventive strategies have an important role in earlier and better combating this complication.

    The development of pulmonary edema is divided in cardiogenic and non-cardiogenic. Cardiogenic edema pathogenically is caused by elevated hydrostatic pressure in the pulmonary capillaries due to left sided congestive heart failure. Non-cardiogenic pulmonary edema is categorized depending on the underlying pathogenesis in low-alveolar pressure, elevated permeability or neurogenic edema. Some important examples of causes are upper airway obstruction like in laryngeal paralysis or strangulation for low alveolar pressure, leptospirosis and ARDS for elevated permeability, and epilepsy, brain trauma and electrocution for neurogenic edema. The differentiation between cardiogenic versus non-cardiogenic genesis is not always straightforward, but most relevant, because treatment markedly differs between the two. Of further importance is the identification of the specific underlying cause in non-cardiogenic edema, not only for therapeutic but particularly for prognostic reasons. Depending on the cause the prognosis ranges from very poor to good chance of complete recovery. PMID:20582896

    Diffusion tensor imaging (DTI) by magnetic resonance imaging (MRI) is now used not only for delineating white matter fiber tracts, but also for assessing the histological characteristics of pathological tissues. Among these uses, predicting the extent or existence of tumor cell invasion into white matter by DTI is under extensive investigation. The previously reported tumor infiltration index (TII) holds great potential for the discrimination of pure vasogenic edema from tumor-infiltrated edema. However, conflicting data are being reported questioning the clinical value of TII. The present investigation reevaluated the utility of TII in patients with meningioma or glioma. We found that TII was unable to discriminate vasogenic from tumor-infiltrated edema. Conversely, detailed voxel-by-voxel comparison of TII and (11)C-methionie PET in the T2-hyperintense area of gliomas showed that TII and (11)C-methionie PET has a positive correlation, suggesting that, although TII is unable to discriminate the cause of edema, the extent of tumor cell invasion into white matter is depicted in gliomas by TII. These data suggest that TII involves both vasogenic and tumor-infiltrated factors, rather than only a single factor. A more intensive investigation is required to reach a complete understanding of TII. PMID:19696968

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

    The question of whether pulmonary edema develops during exercise on land is controversial. Yet, the development of pulmonary edema during swimming and diving is well established. This paper addresses the current controversies that exist in the field of exercise-induced pulmonary edema on land and with water immersion. It also discusses the mechanisms by which pulmonary edema can develop during land exercise, swimming, and diving and the current gaps in knowledge that exist. Finally, this paper discusses how these fields can continue to advance and the areas where clinical knowledge is lacking. PMID:21660232

    Objectives Time trends on the incidence and characteristics of invasive vulvar cancer in Germany have so far been studied in few local population- and hospital based tumor registries. We aimed to provide an overview on recent developments of vulvar cancer in Germany, using population-based cancer registry data. Methods We analyzed the data on vulvar cancer of eight population-based German cancer registries for the period 1999-2011. ICD-10 codes and ICD-O-3 morphology codes were used to select site and histologic types. The annual percentage change was calculated on age-adjusted incidence rates with a joinpoint regression model. Results A total of 12,711 registered cases of invasive carcinoma of the vulva were included in the analyses, hereof were 12,205 of squamous cell origin. Age-standardized incidence rates of vulvar cancer annually increased by 6.7% (95% confidence limits: 5.6-7.9) from 1.7 per 100,000 women in 1999 to 3.6 per 100,000 women in 2011. An increase was observed among women of all ages, and especially between 30 and 69 years of age. Conclusion The annual incidence of invasive carcinoma of the vulva nearly doubled in the past decade in Germany, considerably exceeding the rates observed in other Western European countries. A combination of changes in risk factors, and documentation practice might have contributed to the observed substantial increase in vulvar cancer incidence. PMID:26020540

    Human papillomavirus (HPVs) are a family of sexually viruses with over 100 different genotypes identified till date. They are associated in 99% of cervical cancers, with HPV16 found in about 50% of cases. They are a cause of the second most common female cancer worldwide. PDT may constitute an alternative treatment for condyloma by HPV. In this work we present the development of a PDT device specifically designed for the treatment of vulvar and vaginal lesions induced by HPV. This equipment has been used in a clinical protocol and it is optically based on 640 nm LED (light emitting diodes) arrays. There are three illumination probes available that were anatomically designed for specific site applications: a 30 mm x 115 mm diffuser cylinder for intravaginal illumination and uniform irradiance of 42 mW/cm2; a 36 mm circular probe with 118 mW/cm2 and a 74 mm circular probe with 57 mW/cm2, both for external illumination. The 10% aminolevulinic acid cream is topically placed over the lesions and 4-6 hours after the application the illumination is performed. The illumination time is set depending on the chosen probe and treatment area to achieve a fluence of 200 J/cm2. In this presentation, the preliminary results of this clinical trial will be presented.

    Treatment of vulvar lichen sclerosus (VLS) in children by topical corticosteroids gives control of symptoms and some resolution of physical signs, but large studies are limited. We report the largest study of 72 prepubertal girls with VLS, 62 of whom were prospectively treated with daily application of an ultrapotent topical corticosteroid (UPTC), clobetasol propionate 0.05% ointment, for 3 months, with a follow-up period of 4-8 years [the remaining 10 patients responded to mild to moderate potency topical corticosteroids (MPTCs)]. The results were compared with a retrospective study of 31 prepubertal girls with VLS treated with MPTCs. MPTCs led to symptom clearance in 32.2% of patients, whereas UPTC led to symptom clearance in 72.6% of patients. Improvement in clinical signs following UPTC occurred in 90.3% of children at 3 months, with total resolution of clinical signs occurring in 29.2% at the 4-year follow-up or at puberty. No serious adverse effects occurred with UPTC treatment. In children with VLS, UPTCs relieve symptoms, resolve signs and possibly prevent scarring. UPTCs should therefore be the treatment of choice for VLS in children. PMID:25477189

    The aim of this study was to evaluate the effectiveness of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) for the treatment of vulvar lichen sclerosus (VLS) and compare its effectiveness with that of clobetasol propionate. Four sessions of topical photodynamic therapy (PDT) were administered at 2-week intervals (n = 20). Clobetasol propionate (0.05%) was used daily for 8 weeks (n = 20). The rate of complete response in the PDT group (14/20) was double that of the clobetasol propionate group (7/20) (p < 0.05, 2 = 4.912). Horizontal visual analogue scores indicated that PDT was more effective than clobetasol propionate. Pain intensity numeric rating scale values for PDT were between 3.05 and 4.45. One month after the final session of PDT, only one patient relapsed and all 7 patients in clobetasol propionate group relapsed. ALA-PDT is a well-tolerated and effective option for the treatment of VLS. PMID:26775671

    Composition of the bacterial microbiome in the vagina and vestibule from 30 women with vulvar vestibulitis syndrome (VVS) and 15 healthy controls were compared by pyrosequencing 16S rRNA amplicons. Vaginal concentrations of interleukin (IL)-1β were determined by ELISA. Questionnaires elicited clinical and symptom data. Eighteen genera were detected in vaginal samples, and 23 genera were identified in vestibule samples, from women with VVS. The genera at both sites and the mean number of genera in subjects with VVS were largely similar to those in control subjects. However, differences were noted including higher proportions of Streptococcus and Enterococcus in women with VVS. Furthermore, Lactobacillus iners was more frequently identified in women with VVS while L. crispatus was more frequent in the control women. The dominant bacterial genera in the vagina closely paralleled the dominant genera present in the corresponding vestibular sample in both groups, leading us to postulate that vaginal secretions are an important source of bacteria present on the vestibule. Vaginal IL-1β levels were similar and varied depending on the dominant bacteria. We conclude in this pilot study that no major differences are apparent in the vagina and vestibule between women with or without VVS, except for an increased prevalence of Streptococcus and L. iners in some women with VVS.

    As previously noted, although visual loss usually does not fall below 20/200 in the presence of ME, it may nevertheless be a significant disability. Additional interventions may include referral to low vision clinics, home health agencies, visual loss support groups, and local or regional blindness agencies to aid the patient's occupational rehabilitation, coping mechanisms, and adaptation responses in the presence of this potentially debilitating process. Control of blood sugar, blood pressure, and the intervention of focal/grid laser treatments to seal leaks and prevent further edema provide the best chance of maintaining useful vision throughout life. Patient education is paramount to improve comprehension of the condition, recommended treatment modalities, and compliance with prescribed regimens. Assessments and interventions related to knowledge and sensory deficits, anxiety, discomfort, ineffective coping mechanisms, and health maintenance behaviors add a quality link in the multidisciplinary approach surrounding the delivery of care to patients with NPDR and clinically significant ME.

    Serotonin syndrome (SS) is a potentially life-threatening condition resulting from excessive central and peripheral serotonergic activity. Clinically, it is a triad of mental-status changes, neuromuscular abnormalities, and autonomic disturbances. It can be caused by intentional self-poisoning, overdose, or inadvertent drug interactions. We report the case of a 58-year-old male with type 2 diabetes mellitus and obsessive compulsive disorder who developed pulmonary edema as a possible complication of SS. SS was caused by a combination of three specific serotonin re-uptake inhibitors (fluoxetine, fluvoxamine, and sertraline), linezolid, and fentanyl. The hospital course was further complicated by difficult weaning from the ventilator. SS was identified and successfully treated with cyproheptadine and lorazepam. The case highlights the importance of effective consultation-liaison and prompt recognition of SS as the presentation may be complex in the presence of co-morbid medical illness. PMID:26997733

    Wear of low-oxygen-transmissible soft contact lenses swells the cornea significantly, even during open eye. Although oxygen-deficient corneal edema is well-documented, a self-consistent quantitative prediction based on the underlying metabolic reactions is not available. We present a biochemical description of the human cornea that quantifies hypoxic swelling through the coupled transport of water, salt, and respiratory metabolites. Aerobic and anaerobic consumption of glucose, as well as acidosis and pH buffering, are incorporated in a seven-layer corneal model (anterior chamber, endothelium, stroma, epithelium, postlens tear film, contact lens, and prelens tear film). Corneal swelling is predicted from coupled transport of water, dissolved salts, and especially metabolites, along with membrane-transport resistances at the endothelium and epithelium. At the endothelium, the Na+/K+ - ATPase electrogenic channel actively transports bicarbonate ion from the stroma into the anterior chamber. As captured by the Kedem–Katchalsky membrane-transport formalism, the active bicarbonate-ion flux provides the driving force for corneal fluid pump-out needed to match the leak-in tendency of the stroma. Increased lactate-ion production during hypoxia osmotically lowers the pump-out rate requiring the stroma to swell to higher water content. Concentration profiles are predicted for glucose, water, oxygen, carbon dioxide, and hydronium, lactate, bicarbonate, sodium, and chloride ions, along with electrostatic potential and pressure profiles. Although the active bicarbonate-ion pump at the endothelium drives bicarbonate into the aqueous humor, we find a net flux of bicarbonate ion into the cornea that safeguards against acidosis. For the first time, we predict corneal swelling upon soft-contact-lens wear from fundamental biophysico-chemical principles. We also successfully predict that hypertonic tear alleviates contact-lens-induced edema. PMID:21820076

    Diabetes mellitus (DM) is a chronic disease that affects 387 million people worldwide. Diabetic retinopathy (DR), a common complication of DM, is the main cause of blindness in the active population. Diabetic macular edema (DME) may occur at any stage of DR, and is characterized by vascular hyperpermeability accompanied by hard exudates within the macula. Medical and surgical therapies have dramatically reduced the progression of DR, and timely intervention can reduce the risk of severe vision loss by more than 90 %. In 2012, intravitreal ranibizumab became the first antivascular endothelial growth factor (anti-VEGF) agent approved for DME and, since then, many reports of the use of ranibizumab for DME have been promising. Randomized, prospective, multicenter clinical trials-most notably, RESOLVE, READ-2, RISE/RIDE, RESTORE, DRCR.net protocol I, and RETAIN-reported improvements in best-corrected visual acuity and decreased central retinal thickness as measured with optical coherence tomography in patients with DME. Similar treatment benefits have also been noted in clinical trials evaluating intravitreal aflibercept and bevacizumab (DAVINCI, VISTA/VIVID, and BOLT) and more recently DRCR.net protocol T. Intravitreal steroids (dexamethasone intravitreal implant and fluocinolone acetonide), particularly in refractory cases, also play a significant role in the management of DME (MEAD/CHAMPLAIN and FAMOUS/FAME studies). In summary, over the last 5 years, blocking VEGF and inflammation has been shown to improve visual outcomes in patients with macular edema due to DM, revolutionizing the treatment of center-involved DME and establishing a new standard of care.

    2015-01-01

    Pulmonary edema clearance is necessary for patients with lung injury to recover and survive. The mechanisms regulating edema clearance from the lungs are distinct from the factors contributing edema formation during injury. Edema clearance is effected via vectorial transport of Na+ out of the airspaces which generates an osmotic gradient causing water to follow the gradient out of the cells. This Na+ transport across the alveolar epithelium is mostly effected via apical Na+ and chloride channels and basolateral Na,K-ATPase. The Na,K-ATPase pumps Na+ out of the cell and K+ into the cell against their respective gradients in an ATP-consuming reaction. Two mechanisms contribute to the regulation of the Na,K-ATPase activity:recruitment of its subunits from intracellular compartments into the basolateral membrane, and transcriptional/translational regulation. Na,K-ATPase activity and edema clearance are increased by catecholamines, aldosterone, vasopressin, overexpression of the pump genes, and others. During lung injury, mechanisms regulating edema clearance are inhibited by yet unclear pathways. Better understanding of the mechanisms that regulate pulmonary edema clearance may lead to therapeutic interventions that counterbalance the inhibition of edema clearance during lung injury and improve the lungs’ ability to clear fluid, which is crucial for patient survival.

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

    The literature on genital and pelvic pain has largely focused on heterosexual women. An online study examined characteristics of vulvar pain in 839 lesbian, bisexual, and heterosexual women 18-45 years of age and investigated associations between relationship qualities such as love and communication with participants' perceptions of pain's influence on relationships. Characteristics of vulvar pain were similar across groups. Groups differed in how they perceived pain to impact their relationships, such that better communication for same-sex couples and more love for mixed-sex couples was associated with the perception of their pain as having less of an effect on their relationship functioning.

    A new entity termed "myoepithelioma-like tumor of the vulvar region (MELTVR)" has been proposed as a rare mesenchymal neoplasm of the vulvar area. Histologically, MELTVRs are usually similar to soft tissue myoepitheliomas; however, they have a characteristic immunoprofile, including positivity for estrogen receptor and negativity for S100 protein, and loss of SMARCB1 expression. In this first known case report of MELTVR, the authors present a case of MELTVR that was histologically categorized in a nonmyxoid spindle-cell tumor group and resembled solitary fibrous tumor rather than soft tissue myoepithelioma.

    Purpose: To examine clinical outcomes and relapse patterns in locally advanced vulvar carcinoma treated using preoperative chemotherapy and intensity modulated radiation therapy (IMRT). Methods and Materials: Forty-two patients with stage I-IV{sub A} (stage I, n=3; stage II, n=13; stage III, n=23; stage IV{sub A}, n=3) vulvar cancer were treated with chemotherapy and IMRT via a modified Gynecological Oncology Group schema using 5-fluorouracil and cisplatin with twice-daily IMRT during the first and last weeks of treatment or weekly cisplatin with daily radiation therapy. Median dose of radiation was 46.4 Gy. Results: Thirty-three patients (78.6%) had surgery for resection of vulva; 13 of these patients also had inguinal lymph node dissection. Complete pathologic response was seen in 48.5% (n=16) of these patients. Of these, 15 had no recurrence at a median time of 26.5 months. Of the 17 patients with partial pathological response, 8 (47.1%) developed recurrence in the vulvar surgical site within a median of 8 (range, 5-34) months. No patient had grade ≥3 chronic gastrointestinal/genitourinary toxicity. Of those having surgery, 8 (24.2%) developed wound infections requiring debridement. Conclusions: Preoperative chemotherapy/IMRT was well tolerated, with good pathologic response and clinical outcome. The most common pattern of recurrence was local in patients with partial response, and strategies to increase pathologic response rate with increasing dose or adding different chemotherapy need to be explored to help further improve outcomes.

  11. Prognostic significance of c-KIT in vulvar cancer: bringing this molecular marker from bench to bedside

    2012-01-01

    Background Vulvar carcinomas are rare tumors, and there is limited data regarding molecular alterations. To our knowledge there are no published studies on c-KIT and squamous cell carcinomas of the vulva (VSCC). Although there are a significant number of other tumor types which express c-KIT, there remains controversy as to its relationship to patient outcome. Thus, we wished to investigate such controversial findings to determine the prognostic importance of c-KIT by evaluating its protein and mRNA expression in VSCCs, correlating these findings with clinicopathological features and Human Papillomavirus (HPV) infection. Methods c-KIT expression was scored by immunohistochemistry (IHC) as positive or negative in 139 formalin-fixed paraffin-embedded (FFPE) cases of vulvar carcinomas arrayed in a tissue microarray (TMA) using the DAKO® A4502 rabbit polyclonal c-KIT antibody (diluted 1:100). c-KIT mRNA was evaluated by qRT-PCR in 34 frozen samples from AC Camargo Hospital Biobank (17 tumoral and 17 non-tumoral samples) using TaqMan probes–Applied Biosystems [Hs00174029_m1]. HPV genotyping was assessed in 103 samples using Linear Array® HPV Genotyping Test kit (Roche Molecular Diagnostics, Basel, Switzerland). All results obtained were correlated with clinical and pathological data of the patients. Results c-KIT protein was positive by immunohistochemistry in 70.5% of the cases and this was associated with a higher global survival (p = 0.007), a higher recurrence-free survival (p < 0.0001), an absence of associated lesions (p = 0.001), lymph node metastasis (p = 0.0053), and HPV infection (p = 0.034). Furthermore, c-KIT mRNA quantitation revealed higher levels of transcripts in normal samples compared to tumor samples (p = 0,0009). Conclusions Our findings indicate that those vulvar tumors staining positively for c-KIT present better prognosis. Thus, positivity of c-KIT as evaluated by IHC may be a good predictor for use of more conservative

    Objectives To explore clinically relevant differences in severity of vulvar and vaginal atrophy (VVA) in postmenopausal women treated with ospemifene compared with placebo. Methods Analysis of two multicenter, randomized, double-blind, 12-week phase-III studies in postmenopausal women (40–80 years, with VVA, treated with ospemifene 60 mg/day or placebo (Study 310 and Study 821)). Severity of vaginal dryness and dyspareunia were evaluated using a four-point scoring system and clinically relevant differences between ospemifene and placebo were analyzed and are presented as improvement (reduction in ≥ 1 unit on four-point scoring system), substantial improvement (reduction in 2–3 units on four-point scoring system) and relief (severity score of mild/none after 12 weeks). Results In Study 310, significantly more women with a most bothersome symptom of dyspareunia had improvement (68.3% vs. 54.1%; p = 0.0255) or relief (57.5% vs. 41.8%; p = 0.0205) in the severity of dyspareunia from baseline to week 12 with ospemifene compared with placebo. For those with a most bothersome symptom of vaginal dryness, significantly more experienced improvement (74.6% vs. 57.7%; p = 0.0101), substantial improvement (42.4% vs. 26.9%; p = 0.0172) and relief (66.1% vs. 49.0%; p = 0.0140) of vaginal dryness from baseline to week 12 with ospemifene compared with placebo. Proportions of women with improvement/substantial improvement/relief of symptoms of vaginal dryness or dyspareunia were similar in Study 821. Clinically relevant differences were noticeable by week 4. Conclusions Treatment with ospemifene was consistently associated with greater improvement, substantial improvement or relief in the severity of the most bothersome symptoms of vaginal dryness or dyspareunia compared with placebo.

    Objective Assessment of 12-month safety of ospemifene 60 mg/day for treatment of postmenopausal women with vulvar and vaginal atrophy (VVA). Methods In this 52-week, randomized, double-blind, placebo-controlled, parallel-group study, women 40–80 years with VVA and an intact uterus were randomized 6 : 1 to ospemifene 60 mg/day or placebo. The primary objective was 12-month safety, particularly endometrial; 12-week efficacy was assessed. Safety assessments included endometrial histology and thickness, and breast and gynecological examinations. Efficacy evaluations included changes from baseline to week 12 in percentage of superficial and parabasal cells and vaginal pH. Results Of 426 randomized subjects, 81.9% (n = 349) completed the study with adverse events the most common reason for discontinuation (ospemifene 9.5%; placebo 3.9%). Most (88%) treatment-emergent adverse events with ospemifene were considered mild or moderate. Three cases (1.0%) of active proliferation were observed in the ospemifene group. For one, active proliferation was seen at end of study week 52, and diagnosed as simple hyperplasia without atypia on follow-up biopsy 3 months after the last dose. This subsequently resolved with progestogen treatment and dilatation and curettage. In six subjects (five ospemifene (1.4%), one placebo (1.6%)) endometrial polyps were found (histopathology); however, only one (ospemifene) was confirmed as a true polyp during additional expert review. Endometrial histology showed no evidence of carcinoma. Statistically significant improvements were seen for all primary and secondary efficacy measures and were sustained through week 52 with ospemifene vs. placebo. Conclusions The findings of this 52-week study confirm the tolerance and efficacy of oral ospemifene previously reported in short- and long-term studies. PMID:23984673

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

    Massive ovarian edema is a rare tumor-like condition found in young women resulting from accumulation of fluid mostly due to partial or intermittent torsion of the ovary or secondary, to a preexisting ovarian lesion. We report a case of a 13-year-old girl presenting with an ovarian mass measuring 16 cm. CA-12-5 levels were slightly elevated. Concerns regarding underlying malignancy led to salpingo-oophorectomy. Pathological evaluation revealed a massive ovarian edema and multiple thromboses of ovarian veins. Differentiating massive ovarian edema from malignant ovarian tumor is crucial to prevent patients from undergoing unnecessary surgery. PMID:23649810

    Clinicians commonly use electrical stimulation (ES) to control acute edema. But, except for anecdotal reports, there is little evidence to support that practice. We recently conducted a series of controlled, blinded studies on several nonhuman animal models to determine the efficacy of several forms of ES, but high-voltage pulsed current (HVPC) in particular, in controlling acute posttraumatic edema. We observed that acute posttraumatic edema is curbed by HVPC when certain protocols are used. Results of these studies suggest to us that wave form, polarity, treatment schedule, intensity and frequency of pulses all influence ES, and that clinical protocols need revision. PMID:16558209

    Several pathogenic bacteria produce adenylyl cyclase toxins, such as the edema factor (EF) of Bacillus anthracis. These disturb cellular metabolism by catalyzing production of excessive amounts of the regulatory molecule cAMP. Here, a structure-based method, where a 3D- pharmacophore that fit the active site of EF was constructed from fragments, was used to identify non-nucleotide inhibitors of EF. A library of small molecule fragments was docked to the EF- active site in existing crystal structures and those with the highest HINT scores were assembled into a 3D-pharmacophore. About 10,000 compounds, from over 2.7 million compounds in the ZINC database, had a similar molecular framework. These were ranked according to their docking scores, using methodology that was shown to achieve maximum accuracy (i.e., how well the docked position matched the experimentally determined site for ATP analogues in crystal structures of the complex). Finally, 19 diverse compounds with the best AutoDock binding/docking scores were assayed in a cell based assay for their ability to reduce cAMP secretion induced by EF. Four of the test compounds, from different structural groups, inhibited in the low micromolar range. One of these has a core structure common to phosphatase inhibitors previously identified by high-throughput assays of a diversity library. Thus, the fragment based pharmacophore identified a small number of diverse compounds for assay, and greatly enhanced the selection process of advanced lead compounds for combinatorial design.

    The ultrasonic method was used in acute experiments on cats with open chest under artificial lung ventilation to obtain blood flow in low-lobar pulmonary artery and vein, the blood pressure in pulmonary artery, as well as the left atrial pressure in fat (olive oil) and mechanical (Lycopodium spores) pulmonary embolism. It is shown that pulmonary embolism produces the decrease in the blood flow in pulmonary artery and vein, the increase of the pressure in pulmonary artery and left atria, the increase of lung vessels resistance. The decrease is observed of systemic arterial pressure, bradycardia, and extrasystole. After 5-10 min the restoration of arterial pressure and heart rhythm occur and partial restoration of blood flow in pulmonary artery and vein. In many experiments the blood flow in vein outdoes that in the artery--it allows to suppose the increase of the blood flow in bronchial artery. After 60-90 min there occur sudden decrease of systemic arterial pressure, the decrease of the blood flow in pulmonary artery and vein. The pressure in pulmonary artery and resistance of pulmonary vessels remain high. Pulmonary edema developed in all animals. The death occurs in 60-100 min after the beginning of embolism.

    Vulvar cancer (VC) represents about 4% of gynecologic malignancies, its incidence increases with age and peak incidence is found between 70-79 years. In cases of locally advanced disease surgery is often required and radical vulvectomy, with or without mono-bilateral inguino-femoral lymphadenectomy, is standard management. Various devices have been implemented in gynecological surgery in an attempt to minimize or avoid frequent intra/postoperative complications linked to energy use, unfortunately the majority of these devices require monopolar or bipolar energy. Ultracision® represents a unique surgical device capable of performing both cutting and coagulation at different intensities without use of electric energy. The use of Ultracision® in the radical treatment of VC has advantages both in terms of intraoperative and postoperative complications responsible for the reduction of surgical time and blood loss, complete tissue removal according to oncological criteria, diminished desensitization of peripheral areas and reduction of wound complications. These advantages have been widely demonstrated and contribute to making Ultracision® a cost-effective option in the routine treatment of patients affected by vulvar cancer especially when considering its safety in cardiopathic patients with implanted pacemaker. If the impressive results achieved in radical vulvar surgery will be confirmed, scalpel use could be proposed as routine for surgery of the routinely in surgical approach of vulvar and perineal area, in both benign and malignant disease.

    Several studies have shown that a woman’s vaginal or axillary odors convey information on her attractivity. Yet, whether such scents induce psychoneuroendocrinological changes in perceivers is still controversial. We studied if smelling axillary and vulvar odors collected in the periovulatory and late luteal phases of young women modify salivary testosterone and cortisol levels, as well as sexual desire in men. Forty-five women and 115 men, all of them college students and unacquainted with each other, participated in the study. Female odors were collected on pads affixed to the axilla and on panty protectors both worn the entire night before experiments. Men provided five saliva samples, a basal one before the smelling procedure, and four more 15, 30, 60, and 75 min after exposure to odors. Immediately after smelling the odor source, men answered a questionnaire rating hedonic qualities of scents, and after providing the last saliva sample they answered questionnaire on sexual desire. We found that periovulatory axillary and vulvar odors increased testosterone and cortisol levels, with vulvar scents producing a more prolonged effect. Luteal axilla odors decreased testosterone and cortisol levels, while luteal vulva odors increased cortisol. Periovulatory axilla and vulva scents accounted for a general increase of interest in sex. These odors were also rated as more pleasant and familiar, while luteal vulvar odors were perceived as intense and unpleasant. PMID:24194730

    In the current S2 guidelines, the standard surgical therapy for patients with vulvar cancer also includes inguino-femoral lymphadenectomy. However, in view of the severe side-effects associated with this approach such as problems with wound healing, lymphoceles and lymphoedema, the search is on for alternative treatments that could decrease treatment-associated morbidity and improve patientsʼ quality of life, particularly for node-negative patients. The sentinel lymph node technique is currently the gold standard in the treatment of unifocal breast cancer (clinically negative axilla), and studies on the use of this technique in the treatment of vulvar cancer are promising. To date, the diagnostic accuracy of this method in vulvar cancer has only been evaluated in a single, one-arm, non-randomised, multicentre study. In preparation for a multicentre study, in 2010 we surveyed 41 German hospitals to investigate how often they used the sentinel lymph node technique compared to inguino-femoral lymphadenectomy. The hospitals were grouped according to hospital size and number of patients treated for vulvar cancer. The decision criteria to determine the type of procedure performed were also investigated. Finally, the hospitals were asked whether they would be willing to participate in a prospective clinical study to evaluate the sentinel lymph node technique in patients with vulvar cancer. The majority of surgeons questioned (73 %) already had some experience with this technique in patients with vulvar cancer. In our survey, 27 % of hospitals carried out inguino-femoral lymphadenectomy, 10 % used the sentinel lymph node technique, and 63 % used both methods. In 24 % of hospitals, the standard procedure consisted of the sentinel lymph node technique supplemented by inguino-femoral lymphadenectomy. Only 20 % of the institutions surveyed in our study carried out sentinel lymph node biopsy alone in accordance with the criteria of the consensus recommendations

    The mechanism of edema formation in the nephrotic syndrome has long been a source of controversy. In this review, through the construct of Starling's forces, we examine the roles of albumin, intravascular volume, and neurohormones on edema formation and highlight the evolving literature on the role of primary sodium absorption in edema formation. We propose that a unifying mechanism of sodium retention is present in the nephrotic syndrome regardless of intravascular volume status and is due to the activation of epithelial sodium channel by serine proteases in the glomerular filtrate of nephrotic patients. Finally, we assert that mechanisms in addition to sodium retention are likely operant in the formation of nephrotic edema. PMID:22718186

    Late onset of corneal edema after cataract surgery is an unusual complication. We report a case of corneal edema presenting one month after cataract surgery. During implantation of the foldable lens, one haptic of the intraocular lens fractured at the optic haptic junction. This caused lens decentration, necessitating an intraocular lens exchange ten days later. The patient was recovering well but presented again two weeks later with a drop in vision due to corneal edema. A retained haptic of the intraocular lens was seen in the inferior anterior chamber angle. After surgical removal of the retained haptic the corneal edema fully resolved. Retained intraocular lens fragments can cause corneal endothelial damage, which may be reversible with an early diagnosis and intervention. PMID:19384021

    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.

    High-altitude pulmonary edema (HAPE) is a lethal, noncardiogenic form of pulmonary edema that afflicts susceptible individuals after rapid ascent to high altitude above 2,500 m. Prevention of HAPE is achieved most effectively by gradual ascent allowing time for proper acclimatization. Certain prophylactic medications may further reduce the risk of ascending to high altitude in individuals with a prior history of HAPE. The most effective and reliable treatment of HAPE is immediate descent and administration of supplemental oxygen. PMID:23478563

    The prediction of ovulation time is one of the most important and yet difficult processes in pig production, and it has a considerable impact on the fertility of the herd and litter size. The objective of this study was to assess the vulvar skin temperature of sows during proestrus and estrus using infrared thermography and to establish a possible relationship between the variations in vulvar temperature and ovulation. The experimental group comprised 36 crossbred Large White × Landrace females, of which 6 were gilts and 30 were multiparous sows. Estrus was detected twice daily and the temperature was obtained every 6 hours from the vulvar area and from two control points in the gluteal area (Gluteal skin temperature [GST]). A third variable, vulvar-gluteal temperature (VGT) was obtained from the difference between the vulvar skin temperature and the GST values. The animals were divided into two subgroups: group A consisting of 11 animals with estrus detected at 6:00 AM, Day 4 postweaning, and group B comprising seven animals with estrus detected at 6:00 AM, Day 5 post-weaning. Both groups showed a similar trend in the VGT. The VGT increased during the proestrus, reaching a peak 24 hours before estrus in group A and 48 hours before estrus in group B. The VGT then decreased markedly reaching the lowest value in groups A and B, respectively, 12 and 6 hours after estrus. Although the time of ovulation was only estimated on the basis of a literature review, the matching between the temporal variations of the VGT values and the predicted time of the peak of estradiol secretion that ultimately leads to the ovulation processes suggests that the VGT values represent a potential predictive marker of the ovulatory events.

    Experimental and clinical studies on the evaluation of water content in cases of brain edema were performed in vivo, using MR proton relaxation times (longitudinal relaxation time, T1; transverse relaxation time, T2). Brain edema was produced in the white matter of cats by the direct infusion method. The correlations between proton relaxation times obtained from MR images and the water content of white matter were studied both in autoserum-infused cats and in saline-infused cats. The correlations between T1 as well as T2 and the water content in human vasogenic brain edema were also examined and compared with the data obtained from the serum group. T1 and T2 showed good correlations with the water content of white matter not only in the experimental animals but also in the clinical cases. The quality of the edema fluid did not influence relaxation time and T1 seemed to represent almost solely the water content of the tissue. T2, however, was affected by the nature of existence of water and was more sensitive than T1 in detecting extravasated edema fluid. It seems feasible therefore to evaluate the water content of brain edema on the basis of T1 values.

    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

    Procedures aimed at the treatment of precancerous lesions and ectopia on the uterine cervix are frequently linked to lesions of anatomical structures. The application of hyaluronic acid (Cicatridine vaginal ovules) promotes accelerated healing of the uterine cervix and acquisition of a normal shape in the uterine cervix canal. Local application of hyaluronic acid in the vagina following radiotherapy due to cancer in the uterine cervix or endometrium favourably affects the healing of post-irradiation lesions in the vagina and improves quality of life. Over 90% of patients responded positively to the application of hyaluronic acid in the form of a cream on dystrophic lesions in the vulva. Hyaluronic acid aids the healing process of post-procedural wounds in the uterine cervix, following radiotherapy applied due to cancer of the uterine cervix, endometrium and in vulvar dystrophy.

    Photodynamic therapy has been described as an effective therapeutic option in selected cases of anogenital lichen sclerosus that are refractory to first-line treatments. However, procedure-related pain is a limiting factor in patient adherence to treatment. The authors report the case of a 75-year-old woman with highly symptomatic vulvar lichen sclerosus, successfully treated with photodynamic therapy. An inhaled 50% nitrous oxide/oxygen premix was administered during sessions, producing a pain-relieving, anxiolytic, and sedative effect without loss of consciousness. This ready-to-use gas mixture may be a well-tolerated and accepted alternative to classical anesthetics in Photodynamic therapy, facilitating patients' adherence to illumination of pain-prone areas.

    Anogenital warts (condyloma acuminatum or venereal warts) are a common sexually transmitted disease in males and females. Common clinical treatment of anogenital warts is conservative, however, in extreme cases conservative therapy is insufficient and surgical excision is required. Giant condyloma acuminata (Buschke-Löwenstein tumour) is an extremely rare clinical type of genital wart, characterised by aggressive down growth into underlying dermal structures. A 55-year-old female presented with cauliflower-like growth over the anogenital and sacral region, earlier diagnosed as condyloma acuminatum which was resistant to conservative therapy. During the period between 2005 and 2008 the patient underwent five surgical procedures. Due to the size and location of the tumour, gynaecological and plastic surgeons were involved in the procedures. In addition, definitive histology examination identified a superficial vulvar carcinoma. PMID:23420321

    The purpose of this planning study was to determine whether intensity-modulated radiation therapy (IMRT) reduces the radiation dose to organs at risk (OAR) when compared with 3D conventional radiation therapy (3D-CRT) in patients with vulvar cancer treated by irradiation. This study also investigated the use of sequential IMRT boost (seq-IMRT) and simultaneous integrated boost (SIB-IMRT) for dose escalation in the treatment of locally advanced vulvar cancer. Five vulvar cancer patients treated in the postoperative setting and 5 patients treated with definitive intent (def-group) were evaluated. For the postoperative group, 3D-CRT and IMRT plans to a total dose (TD) of 45 Gy were generated. For the def-group, 4 plans were generated: a 3D-CRT and an IMRT plan to a TD of 56.4 Gy, a SIB-IMRT plan to a TD of 56 Gy, and a SIB-IMRT with dose escalation (SIB-IMRT-esc): TD of 67.2 Gy. Mean dose and dose-volume histograms were compared using Student's t-test. IMRT significantly (all p < 0.05) reduced the D{sub mean}, V30, and V40 for all OAR in the adjuvant setting. The V45 was also significantly reduced for all OAR except the bladder. For patients treated in the def-group, all IMRT techniques significantly reduced the D{sub mean}, V40, and V45 for all OAR. The mean femur doses with SIB-IMRT and SIB-IMRT-esc were 47% and 49% lower compared with 3D-CRT. SIB-IMRT-esc reduced the doses to the OAR compared with seq-3D-CRT but increased the D{sub max.} for the small bowel, rectum, and bladder. IMRT reduces the dose to the OAR compared with 3D-CRT in patients with vulvar cancer receiving irradiation to a volume covering the vulvar region and nodal areas without compromising the dosimetric coverage of the target volume. IMRT for vulvar cancer is feasible and an attractive option for dose escalation studies.

    To investigate the clinical features and finger symptoms of eosinophilic fasciitis (EF), we reviewed five patients with EF. The chief complaint was pain, edema and/or stiffness of the extremities. The distal extremities were affected in all patients, and there was also proximal involvement in one patient. One patient had asymmetrical symptoms. All four patients with upper limb involvement had limited range of motion of the wrist joints, and three of them complained of finger symptoms. Two of these three patients showed slight non-pitting edema of the hands, and the other one had subcutaneous induration of the forearm. All four patients with lower limb symptoms had limited range of motion of the ankle joints, and two showed edema or induration of the legs. Inflammatory changes in the joints were not detected in any of the patients. Two patients displayed neither objective induration nor edema, and two patients had muscle tenderness. In conclusion, finger symptoms of patients with EF might be caused by fasciitis of the forearms, which leads to dysfunction of the long finger flexors and extensors as well as slight edema of hands. Limited range of motion of wrist and/or ankle joints indicates sensitively distal muscle dysfunction caused by fasciitis. PMID:26248532

    The aim of this study is to report a case of complete regression of diabetic macular edema after subcutaneous injection of exenatide in a patient with type 2 diabetes mellitus. This study is an interventional case report. Blood investigations, complete ophthalmic examinations and optical coherence tomography were performed. A 55-year-old female affected by poorly controlled type 2 diabetes mellitus presented with visual impairment due to macular edema in the right eye. The left eye showed mild edema without visual loss. Best-corrected visual acuity (BCVA) was 20/80 and 20/20, respectively. The patient was encouraged to improve metabolic control, and the antidiabetic therapy was modified combining exenatide 10 μg subcutaneously twice daily to her regimen of oral metformin. The patient did not receive any ocular treatment. A complete tomographic resolution of macular edema was observed after 1 month and BCVA improved to 20/63. These findings were confirmed for the entire 6-month follow-up duration. No ocular or non-ocular adverse events were recorded. This is the first reported case of complete regression of macular edema in a diabetic patient after subcutaneous injection of exenatide. PMID:23925692

    Acute hemorrhagic edema of infancy (AHEI) is a rare acute benign cutaneous leukocytoclastic vasculitis affecting children younger than 24 months of age. Its presentation can be confused with those of urticaria, erythema multiforme, Henoch-Schönlein purpura, idiopathic thrombocytopenia,meningococcemia, Kawasaki disease, and drug rash. We present 2 cases of acute hemorrhagic edema of infancy, discuss the characteristics of AHEI, and compare and contrast AHEI with similar dermatologic presentations. This review provides emergency physicians with the basic knowledge necessary to easily recognize AHEI as a distinct clinical entity. The patients were 19- and 23-month-old females who presented to the pediatric emergency department at St Mary's Hospital,Mayo Clinic in Rochester, Minnesota, with impressive purpuric rashes and edema of the hands and feet after preceding upper respiratory tract infections. Both children had benign courses with complete resolution of clinical findings. These 2 cases typify the presentation of AHEI.Acute hemorrhagic edema of infancy presents with characteristic purpuric lesions and extremity edema. The emergency physician's recognition of these presenting characteristics will help diagnose AHEI, avoid unnecessary procedures and tests, and aid in counseling the patient's parents. PMID:26774545

    Diagnosis of edema, abnormal accumulation of water in tissue, is important for managing various traumatic injuries and diseases. However, there is no established method for real-time, noninvasive monitoring of edema. In severe extensive burn injuries, edema develops both topically and systemically due to the increased permeability of blood vessels. In this study, we examined photoacoustic (PA) monitoring of edema formed in rat burn models. Deep dermal burn with a 20% total body surface area was made in the dorsal skin of rats. Burn and its adjacent nonburn tissues were irradiated with 6-ns light pulses at 1430 nm, which is one of the absorption peak wavelengths of water in the near infrared. The PA signal amplitude increased until 12 - 24 hr postburn, and thereafter it gradually decreased to its initial level; the latter phase (after 24 hr postburn) coincided with a diuretic phase in the rats. There was a significant correlation between the PA signal amplitudes and water contents in the tissue measured by wet/dry weight method. These findings demonstrate the validity of PA measurement for real-time, noninvasive monitoring of edema.

    The aim of this study was to determine the effectiveness of granulocyte-macrophage colony-stimulating factor (GM-CSF) impregnated gauze in preventing or healing radiation-induced dermatitis. Sixty-one patients were irradiated for vulvar carcinoma. Thirty-seven applied steroid cream at irradiated areas throughout radiotherapy (Group A) and 24 patients applied additionally GM-CSF impregnated gauze (40 micrcog/cm2 of skin-irradiated area, twice per day) in addition to the steroid cream, after 20 Gy of irradiation (Group B). The score of skin reactions (P=0.008, chi2 test) and the time interval of radiotherapy interruption (P=0.037, Mann-Whitney U test) were statistically significantly reduced in Group B patients. Multivariate analysis of variance showed for this group not only a significant reduction in the Sum of Gross Dermatitis Scoring (P<0.001, adjusted for Duration of Dermatitis) but also a significant reduction of the healing time (P=0.02, adjusted for Sum of Gross Dermatitis Scoring). The pain grading was less (P=0.014, chi2 test) and pain reduction was noticed sooner after the application of GM-CSF impregnated gauze (P=0.0017, Mann-Whitney U test). Multivariate logistic regression analysis showed that the only significant effect on dermatitis score is due to Body Mass Index (P=0.034) and the application of GM-CSF (P=0.008). GM-CSF impregnated gauze can be effective in preventing and healing radiation-induced dermatitis and in reducing the interruption intervals of radiotherapy for vulvar carcinomas. PMID:11472614

    Vulva cancer is the fourth leading gynaecological malignancy, accounting for approximately 4 % of all gynaecological cancers. Surgery represents the treatment of choice, and cases of advanced or recurrent vulvar cancers are to date a major challenge to multidisciplinary teams. Abdominoperineal excision (APE) in combination with vulvectomy and inguinal lymphadenectomy is the only curative treatment option. Patients' files of all women with squamous cell carcinoma of the vulva who underwent abdominoperineal resection were retrospectively reviewed with special regards to technical challenges the general surgeon will face. Seven women were enrolled in this retrospective study with a median age of 71 years (range 56-79 years). In six patients, the pelvic floor after abdominoperineal excision could be closed by direct suture of the levator muscles. One woman underwent abdominoperineal resection with closure of the defect using a vertical rectus abdominis myocutaneous (VRAM) flap. All women underwent radical vulvectomy, in five patients in combination with bilateral inguinal lymph node dissection. Operation time was 377 min (range 130-505 min). The median overall survival after surgery was 27 months (range 4-84 months), with a calculated 5-year survival rate of 42 %. Women with negative lymph nodes revealed a longer survival time after surgery compared to women with lymph node metastases (15.5 vs. 72 months; p = 0.09). Abdominoperineal excisions represent a powerful tool in the multidisciplinary treatment regimen of advanced or recurrent vulvar cancer. Reconstruction of the pelvic floor usually does not require myocutaneous flaps, even when facing large tumours. Despite high complication rates, radical surgery was a feasible treatment with long-term survival potential without mortality. PMID:27011549

    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.

    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

    A 12-year-old boy developed severe acute respiratory distress during a school break requiring resuscitative measures. The episode started shortly after a short choking episode with a cookie. History, physical examination, laboratory results, chest X-ray, and clinical course supported the diagnosis of negative pressure pulmonary edema (NPPE). NPPE occurring outside a hospital setting, especially following a short episode of choking on a cookie, is rarely reported in children. Understanding the pathophysiological mechanisms contributing to pulmonary edema can help in distinguishing NPPE from other causes of fulminant respiratory distress, and especially from other causes of noncardiogenic pulmonary edema.

    Background Premenstrual syndrome is a group of symptoms linked to the menstrual cycle, and edema is among these symptoms. Physiotherapy is often sought by many patients for the treatment of edema; however, for an adequate prescription of physiotherapeutic procedures, the distribution of edema throughout the body has yet to be characterized. Objective To determine the most frequent symptoms and body regions that present with edema in women during the premenstrual period. Subjects and methods Sixty women with a mean age of 24.6±4.7 years were evaluated during their premenstrual (between days 21 and 28) and menstrual period (between days 1 and 3), and the collected data included body mass, height, biotype (body-fat distribution), face, breast, limb-circumference measurements, and limb-volume estimate, and an adapted version of the Premenstrual Symptoms Screening Tool was used. Statistical analysis was performed using Student’s t-test and the test for equality of two proportions (P≤0.05). Results Premenstrual syndrome was identified in 91.7% of the women, and the most frequent symptoms were irritability (73.33%) and physical symptoms, including swelling (65%), and anxiety (58.3%). Edema was detected in the following areas: facial, epigastric, mammary, umbilical, and pubic, the mid-third of the arms, distal forearm, in both thighs and in the mid-third of the legs determined by circumference measurements, and in both upper and lower limbs, according to the estimated volume. Conclusion In this study population, the most frequent symptoms were irritability, physical symptoms, and anxiety, with distribution of edema in the face, breast, abdomen, pubic area, distal upper limb, and proximal lower limb.

  7. Draining the edema: a new role for aquaretics?

    PubMed

    Bockenhauer, Detlef

    2014-05-01

    Investigations into edema formation in nephrotic syndrome have mostly focused on the primary role of sodium. While there is controversy about whether sodium retention is an inherent aspect of nephrotic syndrome (overfill hypothesis) or a secondary consequence (underfill hypothesis), the critical role of sodium in driving fluid retention is generally accepted. Consequently, treatment of edema is based on enhancing renal sodium excretion, using saluretics to block tubular reabsorption of sodium. However, there is also evidence of renal water retention: urine in nephrotic patients is typically highly concentrated (unless urinary concentrating ability is impaired by loop diuretics), and vasopressin levels are commonly elevated. Consequently, aquaretics, i.e., drugs that inhibit renal water reabsorption, may constitute effective treatments for nephrotic edema. In fact, these drugs are already approved for the treatment of non-nephrotic edematous states, such as those encountered in congestive heart or liver failure. In this edition of Pediatric Nephrology, two case reports raise the possibility that aquaretics may also be helpful in the treatment of nephrotic edema. These case reports provide no solid evidence for such treatment, and there clearly are serious concerns about inducing critical hypovolemia with potentially catastrophically consequences, such as thrombosis and shock. Yet these concerns similarly apply to saluretics, which clinicians routinely use in the treatment of edema. In addition, the described powerful effect of aquaretics with respect to the resolution of edema, as well as our understanding of the underlying physiology, argue for a more systematic, yet careful assessment of these drugs in the treatment of nephrotic syndrome.

    This article describes pulmonary edema in two young, physically healthy individuals following routine intensive dental treatment under general anesthesia. The etiology, diagnosis, prognosis, and treatment are discussed. This paper demonstrates that young, healthy patients may develop pulmonary edema in the perianesthesia period or even during anesthesia itself. Obstructive events, which occur especially in the post extubation period, may trigger this condition, as may other well-known phenomena. Early diagnosis and intensive treatment are mandatory in order to effectively resolve the situation. PMID:10323128

Copious irrigation was performed upon realization of incorrect dye use. Corneal edema and iris discoloration developed during the early postoperative period and persisted at 24-months follow-up. However, keratoplasty was not required. The intracameral use of 1% methylene blue has a cytotoxic effect on the corneal endothelium and iris epithelium. Copious irrigation for at least 30 min using an anterior chamber maintainer may improve outcomes. PMID:27224079

    We previously reported that lung edema clearance was stimulated by dopamine (DA). The purpose of this study was to determine whether the DA-mediated stimulation of edema clearance occurs via an adrenergic or dopaminergic regulation of alveolar epithelial Na, K-ATPase. When isolated perfused rat lungs were coinstilled with DA and SCH 23390 (a specific D(1) receptor antagonist), there was a dose-dependent attenuation of the stimulatory effects of DA. Coinstillation with S-sulpiride (a specific D(2) receptor antagonist) or propranolol (a beta-adrenergic antagonist) did not alter DA-stimulated clearance. Similarly, the specific dopaminergic D(1) agonist fenoldopam increased lung edema clearance, but quinpirole (a specific dopaminergic D(2) agonist) did not. (125)I-SCH 23982 binding studies suggested that D(1) receptors are expressed on alveolar type II (ATII) cells with an apparent dissociation constant (K(d)) of 4.4 nM and binding maximum (Bmax) 9.8 pmol/mg. Consistent with these results, the D(1) receptor messenger RNA (mRNA) and protein were detected in ATII cells by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot analysis, respectively. These data demonstrate a novel mechanism involving the activation of dopaminergic D(1) receptors which mediates DA-stimulated edema removal from rat lungs. PMID:10471628

    Vascular endothelial growth factor-A is a major player in vascular development and a potent vascular permeability factor under physiological and pathological conditions by binding to a decoy receptor Flt1 and its primary receptor Flk1. In this study, we show that Flt1 heterozygous (Flt1(+/-)) mouse embryos grow up to adult without life-threatening abnormalities but exhibit a transient embryonic edema around the nuchal and back regions, which is reminiscent of increased nuchal translucency in human fetuses. Vascular permeability is enhanced and an intricate infolding of the plasma membrane and huge vesicle-like structures are seen in Flt1(+/-) capillary endothelial cells. Flk1 tyrosine phosphorylation is elevated in Flt1(+/-) embryos, but Flk1 heterozygosity does not suppress embryonic edema caused by Flt1 heterozygosity. When Flt1 mutants are crossed with Aspp1(-/-) mice which exhibit a transient embryonic edema with delayed formation and dysfunction of lymphatic vessels, only 5.7% of Flt1(+/-); Aspp1(-/-) mice survive, compared to expected ratio (25%). Our results demonstrate that Flt1 heterozygosity causes a transient embryonic edema and can be a risk factor for embryonic lethality in combination with other mutations causing non-lethal vascular phenotype.

    2010-01-01

    Introduction A rare case of optic disc edema associated with cutaneous larva migrans is presented. To the best of our knowledge, this has not been previously reported in literature. Joint management by ophthalmology and tropical medicine teams proved most beneficial for our patient, facilitating correct diagnosis, appropriate investigations and instigation of suitable treatment. Case presentation A 45-year-old Caucasian man, a naturalist, from the UK developed cutaneous larva migrans while in Kenya and presented to us with visual disturbance secondary to unilateral optic disc edema. This resolved after receiving a single dose of ivermectin and visual acuity reverted to normal. Conclusion To the best of our knowledge, optic disc edema associated with cutaneous larva migrans has not been previously reported. This case highlights the importance of taking relevant history of recent travel to endemic areas affected by the nematodes in patients presenting with optic disc edema, and pertinent questioning regarding non-ocular symptoms, including skin lesions. In this case, a history of recent foreign travel and treatment for skin lesions was crucial. PMID:20609253

    Subarachnoid hemorrhage following intracranial aneurysmal rupture is a major cause of morbidity and mortality. Several factors may affect the probability of rupture, such as tobacco and alcohol use; size, shape, and location of the aneurysm; presence of intraluminal thrombus; and even the sex of the patient. However, few data correlate such findings with the timing of aneurysmal rupture. The authors report 2 cases of middle-age women with headache and MRI findings of incidental aneurysms. Magnetic resonance imaging showed evidence of surrounding parenchymal edema, and in one case there was a clear increase in edema during follow-up, suggesting a progressive inflammatory process that culminated with rupture. These findings raise the possibility that bleb formation and an enlargement of a cerebral aneurysm might be associated with an inflammatory reaction of the aneurysm wall resulting in perianeurysmal edema and subsequent aneurysmal rupture. There may be a temporal link between higher degree of edema and higher risk for rupture, including risk for immediate rupture. PMID:25036206

Flk1 tyrosine phosphorylation is elevated in Flt1+/− embryos, but Flk1 heterozygosity does not suppress embryonic edema caused by Flt1 heterozygosity. When Flt1 mutants are crossed with Aspp1−/− mice which exhibit a transient embryonic edema with delayed formation and dysfunction of lymphatic vessels, only 5.7% of Flt1+/−; Aspp1−/− mice survive, compared to expected ratio (25%). Our results demonstrate that Flt1 heterozygosity causes a transient embryonic edema and can be a risk factor for embryonic lethality in combination with other mutations causing non-lethal vascular phenotype.

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

    Objective To evaluate the safety, local tumor efficacy and relief of symptoms of electrochemotherapy (ECT) treatment in patients affected by recurrence of vulvar cancer (VC), unsuitable for standard treatments. Methods Ten patients were recruited with histological diagnosis of recurrence of VC. Intravenous bleomycin was injected, after an accurate mapping of all lesions and ECT was performed. Response to therapy was evaluated and quality of life (QoL) was evaluated via questionnaires. Results Diagnosis stage of primary tumors, according to the FIGO system, was: four patients respectively at stage IB (40%), and at stage II (40%), one patient at stage IIIA (10%), one patient with Paget cancer (10%). Mean age was 76 years (SD ± 7) at time of enrollment. Eight patients (80%) were previously submitted to surgery and/or radio-chemotherapy. Mean treatment time was 20 (range 10-20) min. After a median follow-up of 12 (3-22) months, six patients (60%) were alive. Conclusions Objective responses (ORs) with local control of the tumor were obtained in 80%. After a mean follow-up of 12 (3-22) months six patients (60%) were alive. The favorable outcome of this study, indicates that ECT is a reliable treatment option that may improve their functioning, thus enhancing the care provided in the palliative setting. PMID:26882959

    Vulvar and vaginal atrophy (VVA) is a common complaint in postmenopausal women and consists of a variety of symptoms and strong repercussions that negatively affect comfort during sexual activity and ultimately impact quality of life. The EU and US REVIVE surveys have detected significant barriers in health-care professional management and educational programs that prevent correct diagnosis and effective treatment. This was common in both Europe and the US, but differential behaviors and patterns could be detected after reviewing the published results. The frequency of reporting VVA symptoms was lower in European participants. However, a better knowledge that VVA is a consequence of menopause was evident in Europe, probably in relation to more frequent gynecological visits and more frequent specialist visits as a referral health-care professional. Moreover, a trend towards an improved satisfaction with management by the health-care professional was observed in Europe. European participants acknowledged a significantly higher impact of VVA symptoms on sexual intercourse and partner interaction than North American (US) participants, and both cohorts were observed to have differences between their respective VVA symptom profiles. These observations have implications in the overall concerns that participants stated with long-term VVA medication and for the optimal therapeutic approach, providing evidence to support the concept that unexplored methods to improve management of patients with VVA remain.

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

    Massive ovarian edema (MOE) is a rare entity characterized by an accumulation of stromal edema fluid and occurs primarily in young women. The etiology is not clear, but is suspected to be the result of partial torsion of the ovary. After the establishment of a correct diagnosis, organ-sparing surgical treatment is the standard treatment. With the assistance of laparoscopy, we diagnosed and managed MOE in a 26-year-old woman who had a 4-year history of primary infertility and intermittent lower abdominal pain that had lasted for more than 6 months. With de-torsion, wedge resection, and plication of the ovary, the patient was successfully relieved of the abdominal pain and experienced no recurrence in the follow-up period. A later spontaneous pregnancy demonstrated the practicality of this conservative treatment. PMID:16835988

    To investigate the role of posterior hypothalamus and central neurotransmitters in the pulmonary edema due to hypobaric hypoxia, rats were placed in a high altitude simulation chamber (barometric pressure-294.4 mmHg) for 24 h. Exposure to hypobaric hypoxia resulted in increases in mean arterial blood pressure, renal sympathetic nerve activity, right ventricular systolic pressure, lung wet to dry weight ratio and Evans blue dye leakage. There was a significant attenuation in these responses to hypobaric hypoxia (a) after lesioning posterior hypothalamus and (b) after chronic infusion of GABAA receptor agonist muscimol into posterior hypothalamus. No such attenuation was evident with the chronic infusion of the nitric oxide donor SNAP into the posterior hypothalamus. It is concluded that in hypobaric hypoxia, there is over-activity of posterior hypothalamic neurons probably due to a local decrease in GABA-ergic inhibition which increases the sympathetic drive causing pulmonary hypertension and edema.

    2014-08-01

    Vascular endothelial growth factor (VEGF) plays a pivotal role in the development of diabetic macular edema (DME), the leading cause of vision loss among working-aged individuals. A decade of clinical trials demonstrated that drugs that bind soluble VEGF restore the integrity of the blood-retinal barrier, resolve macular edema, and improve vision in most patients with DME. Four drugs (pegaptanib, ranibizumab, bevacizumab, and aflibercept) effectively treat DME when administered by intravitreal injections. Only ranibizumab has received U.S. Food and Drug Administration (FDA) approval for DME, but bevacizumab is commonly used off-label, and an FDA application for aflibercept is pending. Effective treatment requires repeated injections, although recent data suggest that the treatment burden diminishes after 1 year. Intravitreal therapy is generally safe, although the incidence of systemic thromboembolic events varies among trials. PMID:24919750

    Summary Assessing the pathology of the synovium, its thickening and increased vascularity through ultrasound and magnetic resonance examinations (more often an ultrasound study alone) is still considered a sensitive parameter in the diagnosis of rheumatoid arthritis and in monitoring of treatment efficacy. Magnetic resonance studies showed that, aside from the joint pannus, the subchondral bone tissue constitutes an essential element in the development of rheumatoid arthritis. Bone marrow edema correlates with inflammation severity, joint destruction, clinical signs and symptoms of rheumatoid arthritis, and thus is considered a predictor of rapid radiological progression of the disease. The newest studies reveal that bone marrow edema may be a more sensitive indicator of the response to therapy than appearance of the synovium. Bone marrow edema presents with increased signal in T2-weighted images, being most visible in fat saturation or IR sequences (STIR, TIRM). On the other hand, it is hypointense and less evident in T1-weighted images. It becomes enhanced (hyperintense) after contrast administration. Histopathological studies confirmed that it is a result of bone inflammation (osteitis/osteomyelitis), i.e. replacememt of bone marrow fat by inflammatory infiltrates containing macrophages, T lymphocytes, B lymphocytes, plasma cells and osteoclasts. Bone marrow edema appears after a few weeks from occurrence of symptoms and therefore is considered an early marker of inflammation. It correlates with clinical assessment of disease activity and elevated markers of acute inflammatory phase, i.e. ESR and CRP. It is a reversible phenomenon and may become attenuated due to biological treatment. It is considered a “herald” of erosions, as the risk of their formation is 6-fold higher in sites where BME was previously noted PMID:23493495

    Background Axillary web syndrome (AWS) is a condition that may develop following breast cancer surgery and that presents as a palpable axillary cord of tissue. Objective The purposes of this study were: (1) to determine the clinical characteristics of AWS related to movement, function, pain, and postoperative edema and (2) to define the incidence of and risk factors for AWS within the first 3 months following breast cancer surgery. Design This was a prospective cohort study with a repeated-measures design. Methods Women who underwent breast cancer surgery with sentinel node biopsy or axillary lymph node dissection (N=36) were assessed for AWS, shoulder range of motion, function, pain, and postoperative edema (using girth measurements, bioimpedance, and tissue dielectric constant) at 2, 4, and 12 weeks. Demographic characteristics were used for risk analysis. Results Seventeen women (47.2%) developed AWS, and AWS persisted in 10 participants (27.8%) at 12 weeks. Abduction range of motion was significantly lower in the AWS group compared with the non-AWS group at 2 and 4 weeks. There were no differences between groups in measurements of function, pain, or edema at any time point. Trunk edema measured by dielectric constant was present in both groups, with an incidence of 55%. Multivariate analysis determined lower body mass index as being significantly associated with AWS (odds ratio=0.86; 95% confidence interval=0.74, 1.00). Limitations Limitations included a short follow-up time and a small sample size. Conclusion Axillary web syndrome is prevalent following breast/axilla surgery for early-stage breast cancer and may persist beyond 12 weeks. The early consequences include movement restriction, but the long-term effects of persistent AWS cords are yet unknown. Low body mass index is considered a risk factor for AWS. PMID:25977305

The mean time to the onset of symptoms was 3 +/- 1.3 days after arrival. Common symptoms were dyspnea, cough, headache, chest congestion, nausea, fever, and weakness. Orthopnea, hemoptysis, and vomiting were rare, occurring in 7%, 6%, and 16%, respectively. Symptoms of cerebral edema occurred in 14%. A temperature exceeding 100 degrees F occurred in 20%, and 17% had a systolic blood pressure of 150 mm of mercury or higher. Blood pressures were higher in patients older than 50 years (142 mm of mercury). Rales were present in 85%, and a pulmonary infiltrate was present in 88%; both were most commonly bilateral or on the right side. The amount of infiltrate was mild. Men appeared to be more susceptible than women to high-altitude pulmonary edema. Pulse oximetry in 45 patients showed a mean oxygen saturation of 74% (38% to 93%). Treatment methods depended on severity and included a return to quarters for portable nasal oxygen, an overnight stay in the clinic for continuing oxygen, or a descent to Denver for recovery or admission to a hospital. All patients received oxygen for 2 to 4 hours in the clinic. There were no deaths or complications. Images Figure 2. Figure 3. PMID:8775933

    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.

    2014-03-01

    Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index < 2.2l/min/m(2). The process typically presents with hypotension (systolic blood pressure < 90 mmHg or a decrease in mean arterial pressure > 30 mmHg) and absent or reduced diuresis (< 0.5 ml/kg/h). The most common cause is left ventricular failure due to acute myocardial infarction. Treatment consists of general measures to reverse acidosis and hypoxemia, as well as the use of vasopressors and inotropic drugs. Early coronary revascularization has been demonstrated to improve survival in shock associated with ischaemic heart disease. PMID:24930078

    Cytotoxic brain edema triggered by neuronal swelling is the chief cause of mortality following brain trauma and cerebral infarct. Using fluorescence lifetime imaging to analyze contributions of intracellular ionic changes in brain slices, we find that intense Na(+) entry triggers a secondary increase in intracellular Cl(-) that is required for neuronal swelling and death. Pharmacological and siRNA-mediated knockdown screening identified the ion exchanger SLC26A11 unexpectedly acting as a voltage-gated Cl(-) channel that is activated upon neuronal depolarization to membrane potentials lower than -20 mV. Blockade of SLC26A11 activity attenuates both neuronal swelling and cell death. Therefore cytotoxic neuronal edema occurs when sufficient Na(+) influx and depolarization is followed by Cl(-) entry via SLC26A11. The resultant NaCl accumulation causes subsequent neuronal swelling leading to neuronal death. These findings shed light on unique elements of volume control in excitable cells and lay the ground for the development of specific treatments for brain edema. PMID:25910210

    Acute hemorrhagic edema of young children is an uncommon but likely underestimated cutaneous leukocytoclastic vasculitis. The condition typically affects infants 6-24 months of age with a history of recent respiratory illness with or without course of antibiotics. The diagnosis is made in children, mostly nontoxic in appearance, presenting with nonpruritic, large, round, red to purpuric plaques predominantly over the cheeks, ears, and extremities, with relative sparing of the trunk, often with a target-like appearance, and edema of the distal extremities, ears, and face that is mostly non-pitting, indurative, and tender. In boys, the lesions sometimes involve the scrotum and, more rarely, the penis. Fever, typically of low grade, is often present. Involvement of body systems other than skin is uncommon, and spontaneous recovery usually occurs within 6-21 days without sequelae. In this condition, laboratory tests are non-contributory: total blood cell count is often normal, although leukocytosis and thrombocytosis are sometimes found, clotting studies are normal, erythrocyte sedimentation rate and C-reactive protein test are normal or slightly elevated, complement level is normal, autoantibodies are absent, and urinalysis is usually normal. Experienced physicians rapidly consider the possible diagnosis of acute hemorrhagic edema when presented with a nontoxic young child having large targetoid purpuric lesions and indurative swelling, which is non-pitting in character, and make the diagnosis either on the basis of clinical findings alone or supported by a skin biopsy study.

    Myocardial interstitial edema forms as a result of several disease states and clinical interventions. Acute myocardial interstitial edema is associated with compromised systolic and diastolic cardiac function and increased stiffness of the left ventricular chamber. Formation of chronic myocardial interstitial edema results in deposition of interstitial collagen, which causes interstitial fibrosis. To assess the effect of myocardial interstitial edema on the mechanical properties of the left ventricle and the myocardial interstitium, we induced acute and chronic interstitial edema in dogs. Acute myocardial edema was generated by coronary sinus pressure elevation, while chronic myocardial edema was generated by chronic pulmonary artery banding. The pressure-volume relationships of the left ventricular myocardial interstitium and left ventricular chamber for control animals were compared with acutely and chronically edematous animals. Collagen content of nonedematous and chronically edematous animals was also compared. Generating acute myocardial interstitial edema resulted in decreased left ventricular chamber compliance compared with nonedematous animals. With chronic edema, the primary form of collagen changed from type I to III. Left ventricular chamber compliance in animals made chronically edematous was significantly higher than nonedematous animals. The change in primary collagen type secondary to chronic left ventricular myocardial interstitial edema provides direct evidence for structural remodeling. The resulting functional adaptation allows the chronically edematous heart to maintain left ventricular chamber compliance when challenged with acute edema, thus preserving cardiac function over a wide range of interstitial fluid pressures.

    The inflammatory response induced by Bothrops lanceolatus venom (BLV) in the rat hind-paw was studied measuring paw edema. Non-heated BLV (75microg/paw) caused a marked paw edema accompanied by intense haemorrhage whereas heated venom (97 degrees C, 30s; 12.5-100microg/paw) produced a dose- and time-dependent non-haemorrhagic edema. The response with heated BLV was maximal within 15min disappearing over 24h. Heated venom was then routinely used at the dose of 75microg/paw. The prostacyclin analogue iloprost (0.1microg/paw) potentiated by 125% the venom-induced edema. The histamine H(1) receptor antagonist mepyramine (6mg/kg) or the serotonin/histamine receptor antagonist cyproheptadine (6mg/kg) partially inhibited BLV-induced edema whereas the combination of both compounds virtually abolished the edema. The lipoxygenase inhibitor BWA4C (10mg/kg), but not the cyclooxygenase inhibitor indomethacin (10mg/kg), significantly inhibited the edema (35% reduction; P<0.05). Dexamethasone (1mg/kg) also markedly (P<0.001) reduced venom-induced edema. The bradykinin B(2) receptor antagonist Hoe 140 (0.6mg/kg) reduced by 30% (P<0.05) the venom induced edema, whereas the angiotensin-converting enzyme inhibitor captopril (300microg/paw) potentiated by 42% (P<0.05) the edema. Bothrops lanceolatus antivenon (anti-BLV) reduced by 28% (P<0.05) the venom-induced edema while intravenous administration of antivenom failed to affect the edema. In conclusion, BLV-induced rat paw edema involves mast cell degranulation causing local release of histamine and serotonin, a phenomenon mediated mainly by kinins and lipoxygenase metabolites. Additionally, the use of a specific Bothrops lanceolatus antivenom, given subplantarily or intravenously, revealed to be little effective to prevent BLV-induced edema. PMID:11137542

    Objective To evaluate treatment outcomes for patients with vulvar cancer with grossly positive pelvic lymph nodes (PLNs). Methods From a database of 516 patients with vulvar cancer, we identified patients with grossly positive PLNs without distant metastasis at initial diagnosis. We identified 20 patients with grossly positive PLNs; inclusion criteria included PLN 1.5 cm or larger in short axis dimension on CT/MRI (n=11), FDG-avid PLN on PET/CT (n=3), or biopsy-proven PLN disease (n=6). Ten patients were treated with chemoradiation (CRT) therapy, 4 with RT alone, and 6 with various combinations of surgery, RT or CRT. Median follow-up time for patients who had not died of cancer was 47 months (range, 4-228 months). Results Mean primary vulvar tumor size was 6.4 cm; 12 patients presented with 2009 AJCC T2 and 8 with T3 disease. All patients had grossly positive inguinal nodes, and the mean inguinal nodal diameter was 2.8 cm. The 5-year overall survival and disease specific survival rates were 43% and 48%, respectively. Eleven patients had recurrences, some at multiple sites. There were 9 recurrences in the vulva, but no isolated nodal recurrences. Four patients developed distant metastasis within 6 months of starting radiation therapy. Conclusions Aggressive locoregional treatment can lead to favorable outcomes for many patients with grossly involved PLNs that is comparable to that of grossly involved inguinal nodes only. We recommend modification of the FIGO stage IVB classification to more accurately reflect the relatively favorable prognosis of patients with PLN involvement. PMID:25524458

    The aim of this study was to compare morphologic assessment and p16 immunohistochemistry (IHC) in the determination of human papilloma virus (HPV) status in vulvar squamous cell carcinoma (VSCC). A total of 201 invasive VSCC cases were classified as "HPV-associated" when warty/basaloid VSCC or high-grade squamous intraepithelial lesion (vulvar intraepithelial neoplasia 2/3) was observed, or "HPV-independent" in the presence of well-differentiated keratinizing invasive SCC or differentiated vulvar intraepithelial neoplasia. For p16 IHC, strong nuclear and cytoplasmic staining of all cells in at least the lowermost third of the epithelium was scored as positive. All cases with discrepant HPV predictions by hematoxylin and eosin morphology versus p16 IHC were further analyzed by polymerase chain reaction for HPV DNA. On the basis of hematoxylin and eosin morphologic assessment, 50/201 tumors showed features suggestive of HPV-associated, and 47 of those showed p16 immunoreactivity (94% concordance). Of the 146 cases considered HPV-independent based on hematoxylin and eosin, 115 (79%) showed negative p16 immunostaining. Thus 83% (162/196) concordance between morphologic assessment and p16 IHC was observed, overall. In 34 cases, where morphologic assessment and p16 IHC did not agree, HPV polymerase chain reaction agreed with p16 IHC in 32/34 (94%). The sensitivity and specificity of p16 IHC in classification of VSCC as HPV-independent or HPV-associated was 100% and 98.4%, respectively. Morphologic assessment and p16 IHC are concordant in classifying VSCC as HPV-independent or HPV-associated in a majority of cases (83%). Most of the discrepant cases are p16-positive well-differentiated keratinizing VSCC, and HPV polymerase chain reaction supports classification of a large majority of these (94%) as HPV-associated. p16 IHC is validated as an accurate surrogate marker for determination of HPV status in VSCC.

    BACKGROUND AND PURPOSE Global cerebral edema is an independent predictor of mortality and poor outcomes after aneurysmal SAH. Global cerebral edema, a complex disease process, is thought to be associated with an altered cerebral autoregulatory response. We studied the association between cerebral hemodynamics and early global cerebral edema by using CTP. MATERIALS AND METHODS We retrospectively studied consecutive patients with aneurysmal SAH with admission CTP performed at days 0–3. Two neuroradiologists classified global cerebral edema and hydrocephalus on NCCT performed concurrently with CTP. Global cerebral edema was defined as diffuse effacement of the sulci and/or basal cisterns or diffuse disruption of the cerebral gray-white matter junction. CTP was postprocessed into CBF and MTT maps by using a standardized method. Quantitative analysis of CTP was performed by using standard protocol with ROI sampling of the cerebral cortex. The Fisher exact test, Mann-Whitney test, and independent-samples t test were used to determine statistical associations. RESULTS Of the 45 patients included, 42% (19/45) had global cerebral edema and 58% (26/45) did not. Patient groups with and without global cerebral edema were well-matched for demographic and clinical data. Patients with global cerebral edema were more likely to have qualitative global CTP deficits than those without global cerebral edema (P = .001) with an OR = 13.3 (95% CI, 2.09–138.63). Patients with global cerebral edema also had a very strong trend toward statistical significance, with reduced quantitative CBF compared with patients without global cerebral edema (P = .064). CONCLUSIONS Global perfusion deficits are significantly associated with global cerebral edema in the early phase after aneurysmal SAH, supporting the theory that hemodynamic disturbances occur in global cerebral edema.

    Objectives Approximately 30% of women treated for squamous high-grade intraepithelial neoplasia (VIN3), often associated with human papillomavirus (HPV), have recurrent disease. In this study, we assess predictors of recurrence that may provide targets for early prevention or treatment. Materials and Methods Women with VIN3 who participated in a previous population-based case-control study with blood and tumor samples completed a follow-up telephone interview an average of 5 years after initial diagnosis. The risk of recurrence was determined by proportional hazards modeling. Results Women with VIN3 in the follow-up study (n = 65) were similar to women with VIN3 in the parent study (n = 215) with regard to age at primary diagnosis, level of current cigarette smoking (>60%), and lifetime number of partners. We found that 22 (33.8%) of 65 participants had a vulvar recurrence and that 73.4% recurred within 3 years of treatment. Recurrences occurred more often among women with common warts in the decade before diagnosis (hazard ratio [HR] = 2.5, 95% CI = 1.1–5.8) and among those with a previous anogenital cancer (HR = 2.7, 95% CI = 1.2–6.3). Interestingly, recurrence was less frequent among women who mounted a natural antibody response to HPV16 (HR = 0.4, 95% CI = 0.2–0.9). Conclusions These data provide strong preliminary evidence that VIN3 recurrence was less frequent among those with HPV16 antibodies. Vaccination with the currently licensed HPV vaccine as part of adjunctive therapy for VIN3 would increase antibody response and may decrease risk of recurrence. Randomized controlled trials are needed to determine whether HPV vaccination is effective against VIN3 recurrence. PMID:27224532
