Volume gástrico residual em diabéticos obesos mórbidos após jejum noturno ou 3 horas de suplemento enriquecido com carboidratos: um estudo piloto cruzado randomizado.

RACIONAL: Para reduzir o risco de regurgitação durante a anestesia para procedimentos eletivos, os volumes gástricos residuais (VRG) têm sido tradicionalmente minimizados com jejum noturno. O jejum pré-operatório prolongado tem algumas consequências adversas e tem sido abandonado para a maioria dos procedimentos cirúrgicos, com exceção de pacientes obesos e/ou diabéticos. OBJETIVOS: O objetivo deste estudo foi avaliar o VRG em pacientes diabéticos obesos mórbidos após jejum tradicional ou abreviado. MÉTODOS Este estudo foi aprovado pelo Comitê de Ética em Pesquisa em Seres Humanos da Universidade Federal de Mato Grosso, sob o número 179.017/2012. Este é um projeto prospectivo, randomizado e cruzado em 8 pacientes diabéticos tipo II com obesidade mórbida. O VRG foi medido endoscopicamente após jejum noturno tradicional (pelo menos 8 horas) ou após jejum abreviado (6 horas para sólidos e 3 horas para uma bebida contendo água mais 25 g (12,5%) de maltodextrina). Os dados são expressos como média e variação e as diferenças foram comparadas com testes t pareados em p<0,05. RESULTADOS: A população estudada tinha 41,5 (28-53) anos de idade, peso médio de 135 (113-196) kg, índice de massa corporal (IMC) de 48,2 (40-62,4) kg/m2 e diabetes tipo II de 4,5 (1-10) anos. O VRG após o jejum abreviado foi de 21,5 (5-40) ml versus 26,3 (7-65) ml após o jejum tradicional. Essa diferença não foi significativa (p=0,82). CONCLUSÕES:  O esvaziamento gástrico em pacientes diabéticos obesos mórbidos é semelhante após jejum tradicional ou abreviado com uma bebida com carboidrato.BACKGROUND: To reduce the risk of regurgitation during anesthesia for elective procedures, residual gastric volumes (RGV) have traditionally been minimized with overnight fasting. Prolonged preoperative fasting have some adverse consequences and has been abandoned for most surgical procedures, with the exception of obese and/or diabetic patients.  AIMS: The aim of this study was to assess the RGV in  morbidly obese diabetics patients after traditional or abbreviated fasting. METHODS: This study was approved by the Committee of Ethics in Research in Human Beings from the Federal University of Mato Grosso, number 179.017/2012. This is a prospective, randomized, and cross-over design in 8 morbidly obese type II diabetic patients. RGV was measured endoscopically after either traditional overnight fasting (at least 8 hours) or after abbreviated fasting (6 h for solids and 3 hours for a drink containing water plus 25 g (12.5%) of maltodextrin). Data are expressed as mean and range and differences were compared with paired t tests at p<0.05.  RESULTS: The study population was 41.5 (28-53) years old, with a mean weight of 135 (113-196) kg, body mass index (BMI) 48.2 (40-62.4) kg/m2, and having type II diabetes for 4.5 (1-10) years. The RGV after abbreviated fasting was 21.5 (5-40) ml vs 26.3 (7-65) ml after traditional fasting. This difference was not significant (p=0.82). CONCLUSIONS: Gastric emptying in morbidly obese diabetics patients is similar after either traditional or abbreviated fasting with a carbohydrate drink

An Atypical Case of Lumbar Scheuermanns Disease

Scheuermann diseases true etiology still remains unknown, but there appears to be a strong genetic as well as an environmental contribution. The kyphotic deformity is frequently attributed to "poor posture" which is still resulting in delayed diagnosis. Because of its natural history which has not been clearly defined, treatment modalities and indications remain debated. However, Scheuermann also described changes occur in the disc spaces of the spine which can lead to back pain, there are still some confusions in terminology, diagnosis and the mangement of the disease. We aimed to remind that miscellaneous disease with a brief and different case of report. [Med-Science 2016; 5(2.000): 715-9

Pilonidal sinus disease - Etiological factors, pathogenesis and clinical features

and lsquo;Pilonidal sinus' disease, which is most commonly seen in reproductive populations, such as young adults - mostly in males who are in their twenties - is actually a controversial disease in that there is no consensus on its many facets. It is sometimes seen as an infected abscess draining from an opening or a lesion extending to the perineum. It may also present as a draining fistula opening to skin. In terms of etiological factors, various theories (main theories being congenital and acquired) have been established since it was first described, no universal understanding achieved. A long and significant post-operative care period with different lengths of recovery depending on the type of operation are quite prevalent with regards to recurrence and complication status. In order to prevent recurrence and improve the quality of life, etiological and predisposing factors as well as clinical features of sacrococcygeal pilonidal disease should be well known, a detailed differential diagnosis should be made, and a suitable and timely intervention should be performed. It was aimed here to explain the etiological factors, pathogenesis and clinical features of the disease that may present with various clinical symptoms. [Arch Clin Exp Surg 2016; 5(4.000): 228-232

A Rare Causing of Difficulty in Defecation: Rectal Schwannoma

Objective: Schwannomas are mainly benign, non-epithelial tumors originating in the Schwann cells, which form nerve sheaths. Schwannomas account for about 2-8% of all gastrointestinal mesenchymal tumors, encountered more frequently in the stomach and the small intestine. Schwannomas of the colon and rectum are extremely rare. Case Presentation: In this report, we present a thirty-nine-year-old woman admitted for complaints of rectal fullness and difficulty in defecation. At her rectal examination, a polypoid tumor 22x27x27mm in size was found filling the lumen of the rectum; it was well defined, with a homogeneous nature and benign appearance. Complete excision of the tumor was achieved by a transanal surgical approach. Histolopathological and immunohistochemical diagnosis of the tumor reported a rectal schwannoma. There has been no tumor recurrence at 18 months after surgical excision. Conclusion: A schwannoma of the rectum is rare; a benign tumor can usually be separated from GISTs with immunohistochemical staining, and it carries a good prognosis with local excision, which is the procedure of choice.

Current treatment approaches for ankle ligament injuries: what has changed?

Because of inadequate and unsuccesful management of ALI, undesired chronic disabilities may unluckily be observed. Treatment of these patients should be planned comprehensive and detailed depending on patients diagnosis, injurys severity and stage. Program should not only be focused on to solve edema. An integrated treatment covering injurys acute and subacute period and a comprehensive algorithm including an early rehabilitation program would provide better recovery times.

Anti-adhesive effects of argan oil on postoperative peritoneal adhesions

The aim of this study is to reveal effect of Argan oil on postoperative peritoneal adhesion. Twenty-four Wistar albino rats were divided into three groups. After laparotomy was carried out intraperitoneally, 0,9% NaCl and 3 ml Argan Oil applied to saline and Argan oil groups, respectively. Four subjects in each groups were sacrificed at postoperative day 3 and 7. Macroscopic adhesions and microscopic cellular reactions, such as giant cell, lymphocyte/plasmocyte, neutrophil and histiocyte, were assessed and hydroxyproline levels were measured in all three groups. Adhesion and fibrosis scores were lower both 3rd and 7th days in Argan oil, but only lower fibrosis scores were statistically significant (p [Med-Science 2018; 7(3.000): 557-60

Computer-Aided Detection (Cadx) For Plastic Deformation Fractures In Pediatric Forearm

Bowing fractures are incomplete fractures of tubular long bones, often observed in pediatric patients, where plain radiographic film is the non-invasive imaging modality of choice in routine radiological workflow. Due to weak association between bent bone and distinct cortex disruption, bowing fractures may not be diagnosed properly while reading plain radiography. Missed fractures and dislocations are common in accidents and emergency practice, particularly in children. These missed injuries can result in more complicated treatment or even long-term disability. The most common reason for missed fractures is that junior radiologists or physicians lack expertise in pediatric skeletal injury diagnosis. Not only is additional radiation exposure inevitable in the case of misdiagnosis, but other consequences include the patient\u27s prolonged uncomfortableness and possible unnecessary surgical procedures. Therefore, a computerized image analysis system, which would be secondary to the radiologists’ interpretations, may reduce adverse effects and improve the diagnostic rates of bowing fracture (detection and quantification). This system would be highly desirable and particularly useful in emergency rooms. To address this need, we investigated and developed a new Computer Aided Detection (CADx) system for pediatric bowing fractures. The proposed system has been tested on 226 cases of pediatric forearms with bowing fractures with respect to normal controls. Receiver operation characteristic (ROC) curves show that the sensitivity and selectivity of the developed CADx system are satisfactory and promising. A clinically feasible graphical user interface (GUI) was developed to serve the practical needs in the emergency room as a diagnostic reference. The developed CADx system also has strong potential to train radiology residents for diagnosing pediatric forearm bowing fractures
