Laparoscopic Assisted Vaginal Hysterectomy Versus Vaginal Hysterectomy

Introduction: Hysterectomy is the commonest gynecologic operation, performed for malignant and benign conditions. There are many approaches to hysterectomy for benign disease. Studies comparing the techniques have showed that vaginal hysterectomy has benefits in terms of reduced hospital stay, faster recovery and less operating time. Objective: The purpose of this study is to compare the surgical and immediate postoperative outcomes of Laparoscopic Assisted Vaginal Hysterectomy (LAVH) with those of Vaginal Hysterectomy (VH). Methods: Retrospective descriptive study, comparing two groups of women who underwent LAVH or VH in our department during a 24 months period, from January 2009 to December 2010. The two groups were compared regarding age, vaginal deliveries, previous abdominal surgery, uterine and adnexal pathology, intra-operative and post-operative complications, uterus weight, blood loss and number of days until discharge. Results: In our study 42 LAVH and 99 VH were included, with a patient mean age of 47 and 59, respectively. The most frequent indication for hysterectomy was fibroids (80%) for LAVH and POP(58.6%) for HV. In LAVH group 47.6% of patients had previous abdominal surgery, vs 28.2% in VH group. The medium operative time was 167 minutes for LAVH vs 99 minutes for HV. The intra-operative complications were one case (2%) of accidental incision of rectum in LAVH, and one bladder incision in the VH (1%). There were 3 conversions to laparotomy for difficult technique (7%) in LAVH group. There were no significant post-operative complications for LAVH. In VH group there were 2 cases of haemoperitoneum (2%) and 1 case requiring blood transfusion (1%). The mean time for discharge was 4.23 days for LAVH and 4.46 days for VH. Conclusions: In our study, the main advantage for VH was the reduced operative time. In terms of time to discharge there was no difference between the 2 groups. The main intra-operative complication of LAVH was the risk of conversion to laparotomy, but post-operatively this procedure had fewer complications than VH. In conclusion, LAVH is a safe option for women requiring hysterectomy in cases where VH is anticipated to be technically difficult.

Influence of cardiorespiratory fitness and parental lifestyle on adolescents' abdominal obesity

The aims of this study were (1) to analyse the influence of cardiorespiratory fitness (CRF) and parental overweight status (POS) and socioeconomic status (SES) on abdominal obesity. This study was comprised of 779 adolescents (12-18 years). Waist-height ratio (WHtR), 20 m shuttle-run test to ascertain CRF, POS according to World Health Organization recommendations and SES of parents using level of education were analysed. Using WHtR, the prevalence of abdominal obesity was 21.3% (23.5% girls and 17.9% boys; p = 0.062). Regardless of gender, participants who belonged to the WHtR risk group had significantly (p ≤ 0.05) lower CRF scores than the WHtR non-risk group; 84.4% of girls who belonged to the WHtR risk group had one or two overweight parents (p ≤ 0.05). Boys with low CRF (OR: 6.43; CI: 3.33-12.39) were more likely to belong to the WHtR risk group compared with their lean peers. Girls with low CRF (OR: 1.78; CI: 1.14-2.78) and with at least one overweight parent (OR: 2.50; CI: 1.07-5.85) or two overweight parents (OR: 4.90; CI: 2.08-11.54) were associated with the risk of abdominal obesity. This study highlights the influence of adolescents' family on abdominal obesity, especially in girls. Further, the data suggested that low CRF was a strong predictor of risk values of abdominal obesity in adolescence.

Abdominal angiostrongyliasis with involvement of liver histopathologically confirmed: a case report

Human abdominal angiostrongyliasis is a zoonotic disease caused by ingestion of the L3 larvae of Angiostrongylus costaricensis. The human infection gives rise to a pathological condition characterized by acute abdominal pain, secondary to an inflammatory granulomatous reaction, marked eosinophilia and eosinophilic vasculitis. Most commonly this disease is limited to intestinal location, primary ileocecal, affecting the mesenteric arterial branches and intestinal walls. We present one of the few cases reported around the world with simultaneous involvement of the intestines and liver, including proved presence of nematodes inside the hepatic arteriole.

Transoesophageal Echocardiography for Monitoring Liver Surgery: Data from a Pilot Study

A pilot study aimed to introduce intraoperative monitoring of liver surgery using transoesophageal echocardiography (TEE) is described. A set of TEE measurements was established as a protocol, consisting of left atrial (LA) dimension at the aortic valve plane; mitral velocity flow integral, calculation of stroke volume and cardiac output (CO); mitral annular plane systolic excursion; finally, right atrial area. A total of 165 measurements (on 21 patients) were performed, 31 occurring during hypotension. The conclusions reached were during acute blood loss LA dimension changed earlier than CVP, and, in one patient, a dynamic left ventricular (LV) obstruction was observed; in 3 patients a transient LV systolic dysfunction was documented. The comparison between 39 CO paired measurements obtained by TEE and PiCCO2 revealed a statistically significant correlation (P < 0.001, r = 0.83). In this pilot study TEE successfully answered the questions raised by the anesthesiologists. Larger cohort studies are needed to address this issue.

Influência da atividade muscular abdominal na velocidade do oi tsuki

Introdução: No karaté a região lombo pélvica é importante, pois permite dar estabilidade e potenciar a força produzida na aplicação de técnicas de karaté. Apesar disso, nenhum estudo estuda a influência da atividade muscular abdominal na velocidade de aplicação de técnicas. Existem diversos estudos sobre o karaté mas nenhum deles foca a importância da atividade muscular abdominal. Objetivo: O objetivo deste estudo é verificar se o timing e a magnitude de ativação dos músculos abdominais influenciam a velocidade aplicada na técnica de karaté oi tsuki. Metodologia: Estudo transversal analítico com 7 praticantes de karaté do sexo masculino com graduação de 3º kyu (1º nível de cinturão castanho) ou superior. Foi avaliado o timing e a magnitude de ativação muscular abdominal com eletromiografia de superfície e a velocidade de movimento com sistema Qualisys, durante a execução do oi tsuki. Para dados estatísticos realizou-se o teste de spearman (nível de significância de 0,05) para testar correlação entre timing e a velocidade e entre magnitude de ativação e a velocidade, recorrendo ao coeficiente de determinação para verificar o grau de correlação. Para verificar diferenças bilaterais entre os timings e a magnitude de ativação dos músculos abdominais realizou-se o teste de Wilcoxon (nível de significância de 0,05). Resultados: Foi observada uma relação estatisticamente significativa (p< 0,05) entre o timing de ativação dos músculos transversos/oblíquos internos abdominais e do oblíquo externo contra lateral com a velocidade média do oi tsuki. Os timings de ativação dos músculos retos abdominais e oblíquo externo ipsilateral não revelaram valores de significância (p> 0,05) que possibilitem afirmar que existe relação entre esses timings e a velocidade média do oi tsuki. Não existem valores estatisticamente significativos (p> 0,05) para afirmar que existe relação entre a magnitude de ativação dos músculos abdominais e a velocidade média do oi tsuki. A velocidade máxima do movimento não foi afetada nem pelos timings de ativação dos músculos do abdómen, nem pelas suas magnitudes de ativação. Apenas o timing entre os músculos Transversos/oblíquos internos contra lateral e ipsilateral revelou diferenças. Conclusão: O tronco evidencia ser importante para a prática do karaté, não só pela melhoria da performance, mas também pela melhoria de estabilidade e consequente técnica. Apresenta uma aparente melhoria na velocidade inicial da técnica, podendo afetar positivamente a performance. Para além da performance, contribui para a segurança das estruturas lombo pélvicas, promovendo um menor risco de lesão.

Necrosis of a Guinea Pig Stomach after Contact with Povidone-Iodine: a Case Report

Rodents are the most frequently used animals in surgical experimentation. It is estimated that guinea pigs in particular are the third most commonly used species in this context. To disinfect guinea pigs’ skin, either alcohol or surgical iodine are most often used. In the context of an animal research project, a Nissen operation was performed in an adult male guinea pig. Because of accidental contamination of the operative field, a 10% povidone-iodine cutaneous solution was applied to the serosa of the anterior wall of the stomach and to the gastric fundus. The guinea pig died 12 hours after surgery due to an acute necrotizing hemorrhagic gastritis. Although there have been a few reports of povidone-iodine toxicity in the guinea pig, as far as the authors could determine, this is the first time that such a serious abdominal complication is reported. The authors believe that the possibility of a similar event should be taken into consideration when planning, executing and interpreting experiments in the guinea pig.

Analysis of the Dynamics and Origin of Epileptic Activity in Patients with Tuberous Sclerosis Evaluated for Surgery of Epilepsy

Objective: The epilepsies associated with the tuberous sclerosis complex (TSC) are very often refractory to medical therapy. Surgery for epilepsy is an effective alternative when the critical link between the localization of seizure onset in the scalp and a particular cortical tuber can be established. In this study we perform analysis of ictal and interictal EEG to improve such link. Methods: The ictal and interictal recordings of four patients with TSC undergoing surgery for epilepsy were submitted to independent component analysis (ICA), followed by source analysis, using the sLORETA algorithm. The localizations obtained for the ictal EEG and for the average interictal spikes were compared. Results: The ICA of ictal EEG produced consistent results in different events, and there was good agreement with the tubers that were successfully removed in three of the four patients (one patient refused surgery). In some patients there was a large discrepancy between the localization of ictal and interictal sources. The interictal activity produced more widespread source localizations. Conclusions: The use of ICA of ictal EEG followed by the use of source analysis methods in four cases of epilepsy and TSC was able to localize the epileptic generators very near the lesions successfully removed in surgery for epilepsy. Significance: The ICA of ictal EEG events may be a useful add-on to the tools used to establish the connection between epileptic scalp activity and the cortical tubers originating it, in patients with TSC considered for surgery of epilepsy.

O Eco-Doppler na Dissecção da Aorta Abdominal

Apresenta-se um caso clínico de dissecção da aorta abdominal - tipo B - diagnosticada por eco-Doppler e tomografia axial computorizada (TC). Discute-se o interesse do eco-Doppler no diagnóstico de dissecção da aorta abdominal e na avaliação do envolvimento arterial visceral. É ainda um método útil no follow-up dos doentes com terapêutica conservadora.

Ovarian Borderline Tumor and Fertility-Sparing Surgery

Ovarian borderline tumors (OBTs) are frequently diagnosed in women of reproductive age. There is no consensus about their management, and it sometimes represents a dilemma aboutwhat should be done: fertility sparing surgery or a hysterectomy with salpingo-oophorectomy? Case: A 32-year-old nulligravida, diagnosed with a right ovarian borderline tumor is presented. She underwent pelvic washings, right salpingo-oophorectomy, appendectomy, and omental and peritoneal biopsies (laparotomic approach). Macroscopically, the left ovary was normal and subsequent exploration for staging was also normal, including the lymph nodes. Intraoperatively, frozen section examination was unclear, suggesting an OBT. Results: The final histopathologic diagnosis was ovarian borderline tumor, stage IIC (International Federation of Gynecology and Obstetrics [FIGO] staging). The patient expressed a desire to preserve her fertility. Thirty-six months postsurgery, she became pregnant spontaneously and delivered a healthy newborn at term. Conclusions: Conservative surgery can be performed in young patients treated for an OBT, provided they are closely followed up and that this surgery is performed after careful consideration and informed consent. It is, however, controversial with respect to performing hysterectomy and salpingo-oopherectomy upon the patient’s completion of childbearing.

Ophthalmic Complications of Bariatric Surgery

Obesity is increasing vastly in the world, and the number of bariatric surgeries being performed is also increasing. Patients being submitted to bariatric surgeries, especially malabsorptive procedures, have an increased risk of developing nutrient deficiencies, which can culminate in symptomatic hypovitaminosis, if supplementation is not done correctly. The eye and the optic system need an adequate level of several vitamins and minerals to perform properly, especially vitamin A, and this article wants to cover the main nutrients involved, the possible ophthalmic complications that can arise by their deficiency, and the management of those complications.

A Rare Abdomino-Pelvic Tumor: Paraganglioma

Paragangliomas are rare tumors, with a reported incidence of 2–8 per million. They are chromaffin cell tumors that develop from the neural crest cells and may be divided in tumors derived from the parasympathetic or sympathetic ganglia. We report a case a of a 32-year-old nulliparous woman, referred to our Infertility Clinic. Abdomino-pelvic ultrasound identified a large abdominopelvic tumor, without ovarian origin (both ovaries were identified and had normal morphology). Magnetic Resonance Imaging suggested a right adnexal multicystic, vascularized mass close to iliac vessels and questioning an ovarian origin. At exploratory laparotomy, a 10 cm encapsulated and vascularized mass was found beginning just below right renal artery and extending to the level of the broad ligament. This mass was totally excised and histopathology was consistent with Paraganglioma.

Adenocarcinoma of the Ileum: A Rare and Challenging Entity

INTRODUCTION: Primary small bowel malignancy is unusual and accounts for 1-3% of all gastrointestinal tract neoplasms. Adenocarcinoma is one of the most common histologic types, but its frequency decreases with more distal locations. Its clinical presentation is nonspecific and is usually associated with advanced disease, which contributes to delayed diagnosis. PRESENTATION OF CASE: A 66-year-old woman was admitted to the hospital with a 6-day history of progressively worsening abdominal pain localized in the right lower quadrant, nausea, and vomiting. Investigation revealed an inflammatory appendiceal tumor. The patient underwent surgery and an unexpected tumor involving the distal ileal segment and ileocecal appendix was found. Right radical hemicolectomy with en bloc resection of the distal ileum was performed. Histopathological examination revealed adenocarcinoma of the ileum. DISCUSSION: This rare entity is associated with a nonspecific clinical presentation that contributes to delayed diagnosis and treatment, and consequently to a worse prognosis. Approximately half of the cases are only diagnosed at surgery. Primary treatment consists of wide resection with locoregional lymphadenectomy. The role of adjuvant chemotherapy has yet to be determined. CONCLUSION: This case demonstrates an unusual condition characterized by late and challenging diagnosis. We highlight the importance of an earlier diagnosis and optimal treatment for improved patient outcomes.
