Do transsexuals have micturition disorders?

OBJECTIVE: Transsexualism occurs with an estimated prevalence of 2.4:100,000 male-to-female (MTF) and 1:100,000 female-to-male (FTM) transsexuals. As sex reassignment surgery involves surgery of the urethra and transsexuals are substituted life-long with the cross gender hormones there could possibly arise micturition disorders. Aim of the study was to determine if transsexuals have an increased risk of micturition disorders and if so which. STUDY DESIGN: Between January and July 2003 we examined 25 transsexuals whereof 18 were MTF and 7 were FTM transsexuals using King's Health Questionnaire, visual analogue scale for patient's well being, perineal and transabdominal ultrasound, urine dipstick and uroflow measurement. RESULTS: 17 out of 25 patients considered themselves very happy. In MTF transsexuals, a diverted stream, overactive bladder and stress urinary incontinence was a common problem. Prostate volume was small with 20 g and palpation did not confirm and solid or suspicious lesions. None of the patients had significant residual urine but MTF transsexuals had a reduced urinary flow. We could not detect a current urinary tract infections in any of the patients. CONCLUSION: Transsexuals have an increased risk for the development of micturition disorders including stress urinary incontinence and overactive bladder compared to age-matched control groups and should be counselled preoperatively. Reasons for the development of incontinence might be surgery including pudendal nerve damage, hormonal reasons and ageing.

Iatrogenic sciatic nerve injury in eighteen dogs and nine cats (1997-2006)

OBJECTIVE: To report clinical features associated with iatrogenic peripheral nerve injury in dogs and cats admitted (1997-2006) to a referral teaching hospital. STUDY DESIGN: Retrospective study. ANIMALS: Dogs (n=18), 9 cats. METHODS: Patients had acute signs of monoparesis attributable to sciatic nerve dysfunction that developed after treatment. Neurologic examination and electrodiagnostic testing were performed. Surgical therapy was used for nerve entrapment and delayed reconstructive surgery used in other cases. RESULTS: Of 27 nerve injuries, 25 resulted from surgery (18 with treatment of pelvic injuries). Iliosacral luxation repair resulted in tibial (4 cats) and peroneal (3 dogs) nerve dysfunction. Other causes were intramedullary pinning of femoral fractures (3), other orthopedic surgery (cemented hip prosthesis [2] and tibial plateau-leveling osteotomy [1]), and perineal herniorrhaphy [1]. Nerve injury occurred after intramuscular injection (1 cat, 1 dog). Immediate surgical treatment was removal of intramedullary nails, extruded cement, or entrapping suture. Delayed nerve transplantation was performed in 2 dogs. Within 1 year, 13 patients recovered completely, clinical improvement occurred in 7, and there was no improvement in 7. Five of the 7 dogs that did not recover had acetabular or ilium fracture. CONCLUSION: Iatrogenic sciatic nerve injury occurred most commonly during treatment of pelvic orthopedic diseases and had a poor prognosis. Clinical variation in sciatic nerve dysfunction in dogs and cats can be explained by species anatomic differences. CLINICAL RELEVANCE: Iatrogenic sciatic nerve injury leads to severely debilitating locomotor dysfunction with an uncertain prognosis for full-functional recovery.

Atraumatic splenic rupture in amyloidosis

BACKGROUND: Splenic involvement in amyloidosis is rather frequent (5-10%). An atraumatic rupture of the affected spleen is however an extremely rare event. We report on a patient with undiagnosed amyloidosis who underwent emergency splenectomy for atraumatic splenic rupture. METHODS: Review of the literature and identification of 31 patients, including our own case report, with atraumatic splenic rupture in amyloidosis. Analysis of the clinical presentation, the surgical management, the nomenclature and definition of predisposing factors of splenic rupture. RESULTS: We identified 15 women and 16 men (mean age 53.3 +/- 12.4 years; median 52, range: 27-82 years) with an atraumatic splenic rupture. Easy skin bruisability and factor X deficiency were detected in four (13%) and five patients (16%), respectively. The diagnosis of splenic rupture was made either by computed tomography (n = 12), ultrasound (n = 5), exploratory laparotomy (n = 9) or autopsy (n = 4). All patients underwent surgery (n = 27) or autopsy (n = 4). Amyloidosis was previously diagnosed in nine patients (29%). In the remaining 22 patients (71%), the atraumatic splenic rupture represented the initial manifestation of amyloidosis. Twenty-five patients (81%) suffered from primary (AL) and four patients (13%) from secondary amyloidosis (AA). In two patients, the type of amyloidosis was not specified. A moderate splenomegaly was a common feature (68%) and the characteristic intraoperative finding was an extended subcapsular hematoma with a limited parenchymal laceration (65%). In five patients with known amyloidosis, the atraumatic splenic rupture was closely associated with autologous stem-cell transplantation (ASCT) (16%). Three patients were suffering from multiple myeloma (10%). A biopsy-proven amyloidotic liver involvement was present in 14 patients (45%), which lead to atraumatic liver rupture in two patients. The splenic rupture related 30-day mortality was 26% (8/31). CONCLUSIONS: Atraumatic splenic rupture in amyloidosis is associated with a high 30-day mortality. It occurs predominantly in patients with previously undiagnosed amyloidosis. A moderate splenomegaly, coagulation abnormalities (easy skin bruisability, factor X deficiency) and treatment of amyloidosis with ASCT are considered predisposing factors for an atraumatic splenic rupture.

Development of an ultrasound-guided technique for pudendal nerve block in cat cadavers.

The objective of this prospective experimental cadaveric study was to develop an ultrasound-guided technique to perform an anaesthetic pudendal nerve block in male cats. Fifteen fresh cadavers were used for this trial. A detailed anatomical dissection was performed on one cat in order to scrutinise the pudendal nerve and its ramifications. In a second step, the cadavers of six cats were used to test three different ultrasonographic approaches to the pudendal nerve: the deep dorso-lateral, the superficial dorso-lateral and the median transperineal. Although none of the approaches allowed direct ultrasonographical identification of the pudendal nerve branches, the deep dorso-lateral was found to be the most advantageous one in terms of practicability and ability to identify useful and reliable landmarks. Based on these findings, the deep dorso-lateral approach was selected as technique of choice for tracer injections (0.1 ml 1% methylene blue injected bilaterally) in six cat cadavers distinct from those used for the ultrasonographical study. Anatomical dissection revealed a homogeneous spread of the tracer around the pudendal nerve sensory branches in all six cadavers. Finally, computed tomography was performed in two additional cadavers after injection of 0.3 ml/kg (0.15 ml/kg per each injection sites, left and right) contrast medium through the deep dorso-lateral approach in order to obtain a model of volume distribution applicable to local anaesthetics. Our findings in cat cadavers indicate that ultrasound-guided pudendal nerve block is feasible and could be proposed to provide peri-operative analgesia in clinical patients undergoing perineal urethrostomy.

Lameness and foot lesions in Swiss dairy cows: II. Risk factors.

The objective of this study was to evaluate risk factors associated with foot lesions and lameness in Swiss dairy cows. Potential risk factors were recorded by means of examination of 1'449 Swiss cows and the management systems of 78 farms during routine claw-trimming, and during personal interviews with the associated farmers. Statistical analysis of animal-based and herd level risk factors were performed using multivariate logistic regression models. The risk of being lame was increased in cows affected by digital dermatitis complex, heel-horn erosion, interdigital hyperplasia, Rusterholz' sole ulcer, deep laceration, double sole and severe hemorrhages. Cleanliness, BCS, affection with other foot lesions, breed, importance of claw health to the farmer, frequency of routine claw-trimming, producing according to the guidelines of the welfare label program RAUS, and silage feeding were shown to be associated with the occurrence of some of the evaluated foot lesions and lameness. The identified risk factors may help to improve management and the situation of lameness and claw health in dairy cows in Switzerland and other alpine areas with similar housing and pasturing systems.

THE EXPRESSION AND CELLULAR LOCALIZATION OF CC-CHEMOKINE RECEPTOR 5 (CCR5) AFTER TRAUMATIC BRAIN INJURY

Traumatic brain injury results from a primary insult and secondary events that together result in tissue injury. This primary injury occurs at the moment of impact and damage can include scalp laceration, skull fraction, cerebral contusions and lacerations as well as intracranial hemorrhage. Following the initial insult, a delayed response occurs and is characterized by hypoxia, ischemia, cerebral edema, and infection. During secondary brain injury, a series of neuroinflammatory events are triggered that can produce additional damage but may also help to protect nervous tissue from invading pathogens and help to repair the damaged tissue. Brain microglia and astrocytes become activated and migrate to the site of injury where these cells secrete immune mediators such as cytokines and chemokines. CC-chemokine receptor 5 (CCR5) is a member of the CC chemokine receptor family of seven transmembrane G protein coupled receptors. CCR5 is expressed in the immune system and is found in monocytes, leukoctyes, memory T cells, and immature dendritic cells. Upon binding to its ligands, CCR5 functions in the chemotaxis of these immune cells to the site of inflammation. In the CNS, CCR5 and its ligands are expressed in multiple cell types. In this study, I investigated whether CCR5 expression is altered in brain after traumatic brain injury. I examined the time course of CCR5 protein expression in cortex and hippocampus using quantitative western analysis of tissues from injured rat brain after mild impact injury. In addition, I also investigated the cellular localization of CCR5 before and after brain injury using confocal microscopy. I have observed that after brain injury CCR5 is upregulated in a time dependent manner in neurons of the parietal cortex and hippocampus. The absence of CCR5 expression in microglia and its delayed expression in neurons after injury suggests a role for CCR5 in neuronal survival after injury.

Current aspects and future prospects of total anorectal reconstruction - a critical and comprehensive review of the literature

PURPOSE: Many rectal cancer patients undergo abdominoperineal excision worldwide every year. Various procedures to restore perineal (pseudo-) continence, referred to as total anorectal reconstruction, have been proposed. The best technique, however, has not yet been defined. In this study, the different reconstruction techniques with regard to morbidity, functional outcome and quality of life were analysed. Technical and timing issues (i.e. whether the definitive procedure should be performed synchronously or be delayed), oncological safety, economical aspects as well as possible future improvements are further discussed. METHODS: A MEDLINE and EMBASE search was conducted to identify the pertinent multilingual literature between 1989 and 2013. All publications meeting the defined inclusion/exclusion criteria were eligible for analysis. RESULTS: Dynamic graciloplasty, artificial bowel sphincter, circular smooth muscle cuff or gluteoplasty result in median resting and squeezing neo-anal pressures that equate to the measurements found in incontinent patients. However, quality of life was generally stated to be good by patients who had undergone the procedures, despite imperfect continence, faecal evacuation problems and a considerable associated morbidity. Many patients developed an alternative perception for the urge to defecate that decisively improved functional outcome. Theoretical calculations suggested cost-effectiveness of total anorectal reconstruction compared well to life with a permanent colostomy. CONCLUSIONS: Many patients would be highly motivated to have their abdominal replaced by a functional perineal colostomy. Given the considerable morbidity and questionable functional outcome of current reconstruction technique improvements are required. Tissue engineering might be an option to design an anatomically and physiologically matured, and customised continence organ.

Plate fixation of extra-articular fractures of the proximal phalanx: do new implants cause less problems?

BACKGROUND Limited range of finger motion is a frequent complication after plate fixation of phalangeal fractures. The purpose of this study was to evaluate the results of plate fixation of extra-articular fractures of the proximal phalanx using current low-profile mini-fragment-systems. METHODS From 2006 to 2012, 32 patients with 36 extra-articular fractures of the proximal phalanx of the triphalangeal fingers were treated with open reduction and plate fixation (ORPF) using 1.2 and 1.5 mm mini-fragment systems. Patients presenting with open fractures grade 2 and 3 or relevant laceration of adjacent structures were excluded from the study. We retrospectively evaluated the rate of mal-union or non-union after ORPF, the need for revision surgery, for plate removal, and for tenolysis. Data were analyzed for further complications with regard to infections or complex regional pain syndrome (CRPS). RESULTS No infections were noted. Five patients developed transient symptoms of CRPS. Six weeks postoperatively, total active finger motion (TAM) averaged 183°, and all 32 patients underwent formal hand therapy. At the latest follow-up or at the time of plate removal, respectively, the mean TAM improved to 213°. Extension lag of proximal interphalangeal joints was found in 67 % of all fractured fingers. Secondary surgery was necessary in 14 of 32 patients (2 corrective osteotomies, 12 plate removals including 7 procedures explicitly because of reduced mobility). CONCLUSIONS Despite of new implant designs significant problems persist. Adhesions of extensor tendons leading to limited range of finger motion are still the most frequent complications after ORPF of proximal phalangeal fractures, even in absence of significant soft-tissue damage. LEVEL OF EVIDENCE Therapeutic, Retrospective, Level IV.

Komplikationen beim kathetergestützten Aortenklappenersatz nach transfemoralem Zugang

Hintergund Seit mehr als 10 Jahren wird der kathetergestützte Aortenklappenersatz (Transkatheter-Aortenklappenimplantation, „transcatheter aortic valve implantation“, TAVI) durchgeführt. Bereits in der Anfangsphase haben sich eingriffstypische Komplikationen nach transfemoralem Zugang herauskristallisiert. Ziel der Arbeit Beispielhaft wird anhand von 4 Sektionsfällen beschrieben, wie die Indikationsstellung zur TAVI und die Vermeidbarkeit der Komplikation zu prüfen ist. Material und Methoden Bei einer 86-jährigen Frau war es im Rahmen eines Repositionsversuchs des Implantats zu einem Abriss der rechten Beckengefäße gekommen. Bei einer 82-jährigen Frau war es während der Intervention zu einem Einriss des Aortenklappenrings mit Perikardtamponade gekommen. Eine 89-jährige Frau erlitt während der Intervention eine gedeckte Aortenverletzung und war während der anschließenden operativen Versorgung des Defekts verstorben. Im vierten Fall war bei einer 83 Jahre alt gewordenen Patientin im Rahmen des transfemoralen Klappenersatzes die Positionierung der Klappe misslungen, und ventrikelwärts entwickelte sich eine Embolisation der entfalteten Klappe. Es wurde eine zweite gleichartige Klappe positioniert, die in der Aorta hielt. Ergebnisse Die Indikationsstellung zur TAVI war in den 4 Fällen der multimorbiden Patientinnen gerechtfertigt. Die Komplikationen waren sehr unterschiedlich und die Gefäßverletzungen in 2 Fällen aufgrund der begonnenen Operationen nicht mehr zu prüfen. Schlussfolgerungen Die Versorgung einer Komplikation ist beim indikationsgerechten Patientenkollektiv aufgrund der Multimorbidität extrem schwierig und mit zahlreichen weiteren Komplikationen behaftet.

Structural recovery in lesioned adult mammalian spinal cord by x-irradiation of the lesion site.

Mechanical injury to the adult mammalian spinal cord results in permanent morphological disintegration including severance/laceration of brain-cord axons at the lesion site. We report here that some of the structural consequences of injury can be averted by altering the cellular components of the lesion site with x-irradiation. We observed that localized irradiation of the unilaterally transected adult rat spinal cord when delivered during a defined time-window (third week) postinjury prevented cavitation, enabled establishment of structural integrity, and resulted in regrowth of severed corticospinal axons through the lesion site and into the distal stump. In addition, we examined the natural course of degeneration and cavitation at the site of lesion with time after injury, noting that through the third week postinjury recovery processes are in progress and only at the fourth week do the destructive processes take over. Our data suggest that the adult mammalian spinal cord has innate mechanisms required for recovery from injury and that timed intervention in certain cellular events by x-irradiation prevents the onset of degeneration and thus enables structural regenerative processes to proceed unhindered. We postulate that a radiation-sensitive subgroup of cells triggers the delayed degenerative processes. The identity of these intrusive cells and the mechanisms for triggering tissue degeneration are still unknown.

Cuidar no parto : prática de episiotomia

Enquadramento – A episiotomia é uma incisão feita no períneo para aumentar o canal vaginal com o objetivo de evitar outros traumas perineais durante o parto. No entanto, esta prática, por si só, já se considera um trauma perineal pelo corte em estruturas que podem desencadear problemas futuros. A Organização Mundial de Saúde (1996) recomenda a utilização limitada da episiotomia uma vez que não existem evidências credíveis de que a utilização generalizada ou de rotina desta prática tenha um efeito benéfico. Objetivos: Demonstrar evidência científica dos determinantes da prática de episiotomia seletiva em mulheres com parto normal/eutócico; identificar a prevalência de episiotomia; analisar os fatores (variáveis sociodemográficas, variáveis relativas ao recém-nascido, variáveis contextuais da gravidez e contextuais do parto) que influenciam na ocorrência de episiotomia. Métodos: O estudo empírico I seguiu a metodologia de revisão sistemática da literatura. Efetuou-se uma pesquisa na EBSCO, PubMed, SciELO, RCAAP de estudos publicados entre janeiro de 2008 e 23 de dezembro de 2014. Os estudos encontrados foram avaliados tendo em consideração os critérios de inclusão previamente estabelecidos. Dois revisores avaliaram a qualidade dos estudos a incluir utilizando a grelha para avaliação crítica de um estudo descrevendo um ensaio clínico prospetivo, aleatorizado e controlado de Carneiro (2008). Após avaliação crítica da qualidade, foram incluídos no corpus do estudo 4 artigos nos quais se obteve um score entre 87,5% e 95%. O estudo empírico II enquadra-se num estudo quantitativo, transversal, descritivo e retrospetivo, desenvolvido no serviço de Obstetrícia do Centro Hospitalar Cova da Beira, segundo um processo de amostragem não probabilística por conveniência (n = 382). A recolha de dados efetuou-se através da consulta dos processos clínicos das mulheres com idade ≥ 18 anos que tiveram um parto vaginal com feto vivo após as 37 semanas de gestação. Resultados: Evidência de que a episiotomia não deve ser realizada de forma rotineira, cujo uso deve restringir-se a situações clínicas específicas. A episiotomia seletiva, comparada com a episiotomia de rotina, está relacionada com um menor risco de trauma do períneo posterior, a uma menor necessidade de sutura e a menos complicações na cicatrização. Amostra constituída por 382 mulheres, na faixa etária dos 18-46 anos. Apenas, não se procedeu à episiotomia em 41,7% da amostra, apontando para a presença da episiotomia seletiva. Número significativo de mulheres com parto eutócico (80,5%), com sutura (95,0%), laceração de grau I (64,9%), dor perineal (89,1%) sujeitas a episiotomia (58,3%). A maioria dos recém-nascidos nasceram com peso normal (92,3%), com um valor expressivo de mulheres sujeitas a episiotomia (91,4%). Ainda se constatou a existência de casos, apesar de reduzidos, em que o recém-nascido nasceu macrossómico (5,4%), tendo-se recorrido igualmente a esta prática. Não há uma associação direta entre a realização de episiotomia e os scores do APGAR. Conclusão: Face a estes resultados e com base na evidência científica disponível que recomenda, desde há vários anos, que se faça um uso seletivo da episiotomia, sugere-se que os profissionais de saúde estejam mais despertos para esta realidade, de modo a que se possam anular as resistências e as barreiras de mudanças por parte dos mesmos face ao uso seletivo da episiotomia. Para promover essa mudança de comportamentos é importante não só mostrar as evidências científicas, bem como transpô-las para a prática, capacitando os profissionais de saúde, sobretudo os enfermeiros, na sua atuação. Palavras-chave: Parto Normal/eutócico; Episiotomia; Episiotomia seletiva; Episiotomia de rotina.

Inferior Hypogastric Plexus Block Affects Sacral Nerves and the Superior Hypogastric Plexus

Background. The inferior hypogastric plexus mediates pain sensation through the sympathetic chain for the lower abdominal and pelvic viscera and is thought to be a major structure involved in numerous pelvic and perineal pain syndromes and conditions. Objectives. The objective of this study was to demonstrate the structures affected by an inferior hypogastric plexus blockade utilizing the transsacral approach. Study Design. This is an observational study of fresh cadaver subjects. Setting. The cadaver injections and dissections were performed at the Department of Forensic Sciences and Insurance Medicine, Semmelweis University, Budapest, Hungary after obtaining institutional review board approval. Methods. 5 fresh cadavers underwent inferior hypogastric plexus blockade with radiographic contrast and methylene blue dye injection by the transsacral fluoroscopic technique described by Schultz followed by dissection of the pelvic and perineal structures to localize distribution of the indicator dye. Radiographs demonstrating correct needle localization by contrast spread in the specific tissue plane and photographs of the dye distribution after cadaver dissection were recorded for each subject. Results. In all cadavers the dye spread to the posterior surface of the rectum and the superior hypogastric plexus. The dye also demonstrated distribution to the anterior sacral nerve roots of S1, 2, and 3 with bilateral spread in 3 cadavers and ipsilateral spread in 2 of them. Limitations. The small number of cadaver specimens in this study limits the results and generalization of their clinical significance. Conclusions. Inferior hypogastric plexus blockade by a transsacral approach results in distribution of dye to the anterior sacral nerve roots and superior hypogastric plexus as demonstrated by dye spread in freshly dissected cadavers and not by local anesthetic spread to other pelvic and perineal viscera.
