Epigastric Pain in Acute Renal Infarction: The Forgotten Presentation

Epigastric pain is a manifestation of several medical and surgical conditions. However, when persistent epigastric pain is associated with microscopic or frank haematuria and elevated lactate dehydrogenase (LDH), especially in patients with increased risk of thromboembolic events, acute renal infarction (ARI) should be considered. We report the case of a 77-year-old male patient who presented with sudden persistent epigastric pain and elevated LDH who was found to have atrial fibrillation. The patient was diagnosed with ARI. ARI is not usually a typical differential diagnosis in patients with persistent epigastric pain and elevated LDH in whom the risk of thromboembolic events is high. Thus, physicians should perform a contrast-enhanced CT scan as early as possible to rule out or confirm renal infarction.

A randomised controlled trial comparing the effect of adjuvant intrathecal 2 mg midazolam to 20 micrograms fentanyl on postoperative pain for patients undergoing lower limb orthopaedic surgery under spinal anaesthesia.

Background: Intrathecal adjuvants are added to local anaesthetics to improve the quality of neuraxial blockade and prolong the duration of analgesia during spinal anaesthesia. Used intrathecally, fentanyl improves the quality of spinal blockade as compared to plain bupivacaine and confers a short duration of post-operative analgesia. Intrathecal midazolam as an adjuvant has been used and shown to improve the quality of spinal anaesthesia and prolong the duration of post-operative analgesia. No studies have been done comparing intrathecal fentanyl with bupivacaine and intrathecal 2 mg midazolam with bupivacaine. Objective: To compare the effect of intrathecal 2 mg midazolam to intrathecal 20 micrograms fentanyl when added to 2.6 ml of 0.5% hyperbaric bupivacaine, on post-operative pain, in patients undergoing lower limb orthopaedic surgery under spinal anaesthesia. Methods: A total of 40 patients undergoing lower limb orthopaedic surgery under spinal anaesthesia were randomized to two groups. Group 1: 2.6mls 0.5% hyperbaric bupivacaine with 0.4mls (20micrograms) fentanyl Group 2: 2.6mls of 0.5% hyperbaric bupivacaine with 0.4mls (2mg) midazolam Results: The duration of effective analgesia was longer in the midazolam group (384.05 minutes) as compared to the fentanyl group (342.6 minutes). There was no significant difference (P 0.4047). The time to onset was significantly longer in midazolam group 17.1 minutes as compared to the fentanyl group 13.2 minutes (P 0.023). The visual analogue score at rescue was significantly lower in the midazolam group (5.55) as compared to the fentanyl group 6.35 (P - 0.043). Conclusion: On the basis of the results of this study, there was no significant difference in the duration of effective analgesia between adjuvant intrathecal 2 mg midazolam as compared to intrathecal 20 micrograms fentanyl for patients undergoing lower limb orthopaedic surgery.

A dyadic perspective on genito-pelvic pain : trauma antecedents and treatment effectiveness

La vestibulodynie provoquée (VP) est la forme la plus répandue de douleur génito-pelvienne/trouble de la pénétration et la cause la plus fréquente de douleur vaginale chez les femmes pré-ménopausées. Les femmes qui en souffrent rapportent plus de détresse psychologique ainsi qu’un fonctionnement sexuel appauvri, une diminution de la fréquence des activités sexuelles et du plaisir, et plus d’attitudes négatives à l’égard de la sexualité. Les recherches portant sur les couples souffrant de VP ont montré le rôle prépondérant des variables relationnelles dans la modulation des conséquences sexuelles et psychologiques pour les femmes et leurs partenaires. Cependant, aucune analyse dyadique n’a été appliquée au facteur de risque étiologique le plus robuste, soit la maltraitance durant l’enfance. Par ailleurs, malgré des recommandations répétées pour inclure le partenaire dans le traitement psychologique pour la VP, aucune étude à ce jour n’a examiné l’efficacité d’une psychothérapie qui inclut systématiquement le partenaire et dont la cible est le couple. L’objectif général de cette thèse a été d’utiliser une perspective dyadique afin d’examiner les antécédents de maltraitance et l’efficacité d’une intervention conçue pour améliorer les issues des couples souffrant de VP. Le premier article vise à examiner les liens entre la maltraitance durant l’enfance des femmes souffrant de VP et leurs partenaires, et leur fonctionnement sexuel, leur ajustement psychologique, leur satisfaction conjugale et enfin avec la douleur rapportée par les femmes durant les relations sexuelles. Quarante-neuf couples souffrant de VP ont complété des questionnaires auto-rapportés. La maltraitance durant l’enfance chez les femmes était associée à un fonctionnement sexuel plus faible chez les femmes et les hommes, une augmentation de l’anxiété chez les femmes seulement, et une douleur affective accrue durant les relations sexuelles. La maltraitance durant l’enfance chez les hommes était associée à un fonctionnement sexuel plus faible, moins de satisfaction conjugale, plus d’anxiété chez les femmes et les hommes, et une douleur affective accrue durant les relations sexuelles rapportée par les femmes. En se basant sur les recommandations issues des études empiriques, une thérapie cognitive et comportementale pour les couples (TCCC) souffrant de VP a été développée. Le deuxième article présente les résultats d’une étude pilote testant son efficacité, fidélité et faisabilité potentielles. Neuf couples ont complété des questionnaires auto-rapportés pré- et post-traitement. La TCCC de 12 rencontres était manualisée. Les femmes ont rapporté une amélioration significative de la douleur, du fonctionnement et de la satisfaction sexuels, et les partenaires ont rapporté une amélioration significative de leur satisfaction sexuelle. Les couples ont rapporté des niveaux élevés de satisfaction quant à la psychothérapie, et les psychothérapeutes ont rapporté suivre le manuel de traitement de manière fidèle. Le troisième article, s’appuyant sur les résultats prometteurs de l’étude pilote, décrit le protocole de recherche pour un essai clinique randomisé mesurant l’efficacité de la TCCC comparée à une intervention médicale de première ligne, la lidocaïne topique, pour le traitement de la VP. Enfin, les implications cliniques et théoriques de la thèse sont discutées.

Post-menopausal metrorrhagia - an ovarian thecoma presentation

Os tecomas são tumores raros do ovário, do grupo dos tumores dos cordões sexuais, de natureza sólida e frequentemente unilaterais. Têm maior incidência no período pósmenopausa e normalmente são silenciosos. Quando sintomáticos traduzem-se por dor pélvica e metrorragia (condicionada pela habitual natureza produtora de estrogénios do tumor). Podem ser concomitantes a síndrome de Meigs e/ou de Golin-Goltz e associaremse a transformação benigna ou maligna do endométrio. Embora a ecografia possa ser inespecífica neste contexto, uma avaliação multiparamétrica abrangente em ressonância magnética, incluindo por estudo dinâmico e com ponderação em difusão, permite frequentemente orientar de modo favorável a marcha diagnóstica. Apresentamos um caso raro de tecoma do ovário, com espessamento associado do endométrio, avaliado por ecografia ginecológica por vias supra-púbica e transvaginal bem como tomografia computorizada e ressonância magnética, confirmado cirurgicamente. Tratou-se de uma examinada caucasiana de 61 anos de idade, apresentando-se com metrorragia pósmenopáusica, sem outros sintomas nem contexto familiar relevante. Procedeu-se, a este propósito, a uma revisão da literatura focada no diagnóstico multimodal diferencial, apresentação clínica, tratamento e prognóstico destes tumores.

Surgical infection and malnutrition

Background: Malnutrition in surgical patients is associated with delayed recovery, higher rates of morbidity and mortality, prolonged hospital stay, increased healthcare costs and a higher early re-admission rate. Methods: Data synthesis after review of pertinent literature. Results: The aetiology of malnutrition is multifactorial. In cancer patients, there is an abnormal peripheral glucose disposal, gluconeogenesis, and whole-body glucose turnover. Malnourished cancer patients undergoing major operations are at significant risk from perioperative complications such as infectious complications. Surgical aggression generates an inflammatory response which worsens intermediary metabolism. Conclusions: Nutritional evaluation and nutritional support must be performed in all surgical patients, in order to minimize infectious complications. Enteral nutrition early in the postoperative period is effective and well tolerated reducing infectious complications, improving wound healing and reducing length of hospital stay. Pharmaconutrition is indicated in those patients, who benefit from enteral administration of arginine, omega 3 and RNA, as well as parenteral glutamine supplementation. When proximal sutures are used, tubes allowing early jejunal feeding should be used.

Prevalence of surgical wound infection after surgery for breast cancer: systematic review

One of the known risk factors for abuse and neglect of the elderly is the decrease in functionat capacity, contributíng to self care dependency of instrumental actívities of daily living and basic activities of daily Itving (OMS, 2015). Methods: Cross-sectional study with non probabilistíc sample of 333 elderly, performed in a hospital, homes and day centers for the elderly. The data collectíon protocol tncluded socio-demographic data, Questíons to elicit Elder Abuse (Carney, Kahan B Paris, 2003 adap. By Ferreira Alves & Sousa, 2005), scale of instrumental actívi - ties of daily living Lawton and Brody and Katz index to assess the levei of independence in actívities of daily living. Objectives: To evaluate the assodation between abuse and neglect in the elderly, instrumental actívitíes of daily living and levei of independence in actívitíes of daily living. Results: Emotional abuse is signifícantty correlated with the levei of independence in activities of daity Uving (p = 0. 000), older peopie with less independence tend to have higher leveis of emotional abuse. The total abuse is signtficantly correlated with the leveis of independence in activittes of daily living (p = 0. 002), less independent elderty tend to suffer greater abuse and neglect. There were no statistically significant associations between abuse and neglect and instrumental activities of daily l1v1ng. Conclusions: The less independent elderly are more vulnerable to situatíons of abuse and neglect, being more exposed to emotional abuse. These results point to the need for health professionals/ nurses develop prevention interventions, including strategies to support carers and early screentng tn less independent elderly. Keywords: Elder abuse. Negligence. Nursing care. Frail elderly. PREVALENCE OF SURGICAL WOUND INFECTION AFTER SURGERY FOR BREAST CÂNCER: SYSTEMATIC REVIEW C. Amaral3, C. Teixeira"'1', F. Sousa'', C. Antãoa "Polythecnic Institute o f Bragança, Bragança, Portugal; bEPI Unit, Public Health Institute, University of Porto, Portugal. Contact details: catarinaisabeln.amaraliSsmaU.com Introduction: Breast câncer is one of the most common mahgnant pathology in European countries, as Portugal, where annual inddence is around 90 new cases per 100,000 women. Breast surgery is the usual treatment for this pathology, however such procedure can be complicated by the infection of surgical site. Objectives: To know the prevalence and determtnants of surgtcal wound infection after breast surgery. Methods: We conducted a systematic review by searching of the Web of Sdence electronic database for articles published over the last s1x years 1n developed countries. Over three hundred dtatíons were obtained and after excludtng citations with reasons, fíve artícles met our inclusion criteria and were included in the present review. Results: Prevalence of surgical wound infection varied across studies between 0. 1% and 12. 5%. Bilateral mastectomy is assodated with higher prevalence of wound infectíon than unilateral mastectomy (3. 6% vs 3, 3%), lumpectomy with immediate breast reconstruction (IBR) is related with higher frequency of wound infectíon than surgery with no IBR (0, 5% vs 0, 1%), also, mastectomy with IBR is associated with higher prevalence of wound infectíon than mastectomy wtth no IBR (1, 5% vs 0, 3%) and breast surgery followed by axiltary lymph nade dissectíon is related with higher prevalence of wound infection than surgical procedures wtth no axillary lymph node dissection (2, 82% vs 1, 66%). Conclusions: Nurses that provide post-operatíve care to women after breast surgery should be aware about risk of wound tnfectíon, partícularly after more invasive procedures.

Spinous Process Osteochondroma as a Rare Cause of Lumbar Pain

We present a case of a 5th Lumbar Vertebra (L5) spinous process osteochondroma as a rare cause of lumbar pain in an old patient. A 70-year-old male presented with progressive and disabling lower lumbar pain. Tenderness over the central and left paraspinal area of the lower lumbar region and a palpable mass were evident. CT scan showed a mass arising from the spinous process of L5. Marginal resection of the tumor was performed through a posterior approach. The histological study revealed an osteochondroma. After surgery, pain was completely relieved. After one year there was no evidence of local recurrence or symptoms. Osteochondromas rarely involve the spine, but when they do symptoms like pain, radiculopathy/myelopathy, or cosmetic deformity may occur. The imagiologic exam of election for diagnosis is CT scan. When symptomatic the treatment of choice is surgical resection. The most concerning complication of osteochondromas is malignant transformation, a rare event.

Evaluation of hemosponge in promoting dental socket healing after 3rd mandibular premolar extraction in a feline model

Aim: To investigate the healing process following use of collagen sponges in the dental socket after extraction. Wound complications during the study were also evaluated. Methods: 32 cats were included in this study. IV administration of the combination of diazepam (0.22 mg/kg) and ketamine (10 mg/kg) was used to induce general anesthesia. Surgical extraction of both 3rd mandibular premolars was performed. The open dental sockets were divided in two groups. In Group A, the open dental socket on the left side was closed using 4-0 Monocryl in simple interrupted pattern. In Group B, the right dental socket was filled with lyophilized hydrolyzed collagen and the buccal and lingual flaps were sutured using 4-0 Monocryl and simple interrupted pattern. Meloxicam (0.2 mg/kg) was used to manage the post-extraction pain in all cats. Ampicilline 20 mg/kg was used as prophylaxis. The wounds were observed during the study to evaluate any signs of inflammation or dehiscence. Radiographs were taken to compare healing of the socket 3 weeks after the procedure. A 1 mm biopsy punch sample was taken from sockets in all cats for comparison of the healing in both groups. Results: Hemorrhage occurred only in the sockets of Group A. Remission of radiolucent area occurred in both groups. Mean score of inflammation was lower and mean scores of fibrotic reaction and fibroplasia were higher in Group B (p<0.05). Conclusions: Use of hemosponge in alveolar socket may accelerate fibroplasia and formation of the connective tissue and reduce inflammation after tooth extraction. Therefore, post-extraction use of the hemostatic agent in the dental socket is recommended.

Complications associated with malnutrition in elective surgical patients in a Malaysian setting

Purpose: To identify the level of malnutrition and complications observed in Malaysia. Methods: A prospective, observational study was conducted with the objectives of identifying the degree of malnutrition, complications and the need for nutritional support in elective surgical patients. Collection of data was performed in local tertiary hospitals using a Patient Generated Subjective Global Assessment (PG - SGA) nutritional screening tool and medical records. Results: A total of 50 patients electively admitted for surgery were included. The results demonstrated that there was a significant increase in malnourished patients post-surgery compared to pre-surgery (p = 0.0001). Most interesting was the significant number of complications observed post-surgery compared to pre-surgery (p = 0.035) which was associated to the poor level of nutrition. The most common type of complications noted post-surgery were nosocomial infection, wound infection and readmission. Conclusion: Malnutrition is prevalent pre- and post-operatively in Malaysia. Therefore, focus on the outcome of these malnourished patients should be performed to reduce complications associated with poor nutrition.

Índice acumulativo de riesgo (nice) como prueba diagnóstica con base en tomografía corneal por elevación en la prevención de ectasia corneal post-lasik

Antecedentes La ectasia corneal post-lasik (ECPL) es una complicación infrecuente, pero devastadora en la cirugía lasik (queratomileusis asistida con éxcimer láser) para el tratamiento de la miopía con o sin astigmatismo. Con base en la tomografía corneal por elevación por imágenes de Scheimpflug (Sistema Pentacam HR, Oculus Wetzlar, Alemania), se propone un novedoso índice acumulativo de riesgo para ser utilizado como prueba diagnóstica de tamizaje y así prevenir esta complicación. Metodología Se realizó un estudio observacional analítico, de corte transversal tipo pruebas diagnósticas, con el fin de evaluar las características operativas del índice NICE teniendo como estándar de referencia el módulo de Belin-Ambrosio (Pentacam HR) utilizando un modelo de regresión logística binaria, tablas de contingencia y estimando el área bajo la curva ROC. Resultados Se evaluaron 361 ojos de los cuales el 59,3% provenían de pacientes de sexo femenino, la edad media global fue de 30 años (RIC 11,0). El modelo logístico binario aplicado se construyó con base en cuatro variables independientes cuantitativas (K2, PAQUI, EP e I-S) y una cualitativa (SEXO), y se determinó su relación con la variable dependiente, NICE (puntaje final). Las variables predictoras fueron estadísticamente significativas clasificando adecuadamente el 92,9% de los ojos evaluados según presencia o ausencia de riesgo. El coeficiente de Nagelkerke fue de 74,4%. Conclusiones El índice acumulativo de riesgo NICE es una herramienta diagnóstica novedosa en la evaluación de candidatos a cirugía refractiva lasik para prevenir la ectasia secundaria.

Physiological and symptomatic responses to cycling and walking in intermittent claudication

To shed light on the potential efficacy of cycling as a testing modality in the treatment of intermittent claudication (IC), this study compared physiological and symptomatic responses to graded walking and cycling tests in claudicants. Sixteen subjects with peripheral arterial disease (resting ankle: brachial index (ABI) < 0.9) and IC completed a maximal graded treadmill walking (T) and cycle (C) test after three familiarization tests on each mode. During each test, symptoms, oxygen uptake (VO2), minute ventilation (VE), respiratory exchange ratio (RER) and heart rate (HR) were measured, and for 10 min after each test the brachial and ankle systolic pressures were recorded. All but one subject experienced calf pain as the primary limiting symptom during T; whereas the symptoms were more varied during C and included thigh pain, calf pain and dyspnoea. Although maximal exercise time was significantly longer on C than T (690 +/- 67 vs. 495 +/- 57 s), peak VO2, peak VE and peak heart rate during C and T were not different; whereas peak RER was higher during C. These responses during C and T were also positively correlated (P < 0.05) with each other, with the exception of RER. The postexercise systolic pressures were also not different between C and T. However, the peak decline in ankle pressures from resting values after C and T were not correlated with each other. These data demonstrate that cycling and walking induce a similar level of metabolic and cardiovascular strain, but that the primary limiting symptoms and haemodynamic response in an individual's extremity, measured after exercise, can differ substantially between these two modes.

The Coming of Post-reflexive Society: Commodification and Language in Digital Capitalism

Language is a unique aspect of human communication because it can be used to discuss itself in its own terms. For this reason, human societies potentially have superior capacities of co-ordination, reflexive self-correction, and innovation than other animal, physical or cybernetic systems. However, this analysis also reveals that language is interconnected with the economically and technologically mediated social sphere and hence is vulnerable to abstraction, objectification, reification, and therefore ideology – all of which are antithetical to its reflexive function, whilst paradoxically being a fundamental part of it. In particular, in capitalism, language is increasingly commodified within the social domains created and affected by ubiquitous communication technologies. The advent of the so-called ‘knowledge economy’ implicates exchangeable forms of thought (language) as the fundamental commodities of this emerging system. The historical point at which a ‘knowledge economy’ emerges, then, is the critical point at which thought itself becomes a commodified ‘thing’, and language becomes its “objective” means of exchange. However, the processes by which such commodification and objectification occurs obscures the unique social relations within which these language commodities are produced. The latest economic phase of capitalism – the knowledge economy – and the obfuscating trajectory which accompanies it, we argue, is destroying the reflexive capacity of language particularly through the process of commodification. This can be seen in that the language practices that have emerged in conjunction with digital technologies are increasingly non-reflexive and therefore less capable of self-critical, conscious change.
