Healthcare-Associated Infective Endocarditis: a Case Series in a Referral Hospital from 2006 to 2011

Background: Healthcare-associated infective endocarditis (HCA-IE), a severe complication of medical care, shows a growing incidence in literature. Objective: To evaluate epidemiology, etiology, risk factors for acquisition, complications, surgical treatment, and outcome of HCA-IE. Methods: Observational prospective case series study (2006-2011) in a public hospital in Rio de Janeiro. Results: Fifty-three patients with HCA-IE from a total of 151 cases of infective endocarditis (IE) were included. There were 26 (49%) males (mean age of 47 ± 18.7 years), 27 (51%) females (mean age of 42 ± 20.1 years). IE was acute in 37 (70%) cases and subacute in 16 (30%) cases. The mitral valve was affected in 19 (36%) patients and the aortic valve in 12 (36%); prosthetic valves were affected in 23 (43%) patients and native valves in 30 (57%). Deep intravenous access was used in 43 (81%) cases. Negative blood cultures were observed in 11 (21%) patients, Enterococcus faecalis in 10 (19%), Staphylococcus aureus in 9 (17%), and Candida sp. in 7 (13%). Fever was present in 49 (92%) patients, splenomegaly in 12 (23%), new regurgitation murmur in 31 (58%), and elevated C-reactive protein in 44/53 (83%). Echocardiograms showed major criteria in 46 (87%) patients, and 34 (64%) patients were submitted to cardiac surgery. Overall mortality was 17/53 (32%). Conclusion: In Brazil HCA-IE affected young subjects. Patients with prosthetic and native valves were affected in a similar proportion, and non-cardiac surgery was an infrequent predisposing factor, whereas intravenous access was a common one. S. aureus was significantly frequent in native valve HCA-IE, and overall mortality was high.

Avaliação crítica da cirurgia na hipertensão portal esquistossômica

There are over 100.000 patients affected by schistosomotic portal hipertension, that may suffer rupture of the esophageal varices. Besides the portal hypertension, local factors must be emphazised as responsible for the three distal centimeters of the esophagus, called "zona vulnerável" (vulnerable zone). The beter liver functional reserve of these schistosomotic patients as compared to the cirrhotic, present two favorable condititions: (1) beter possibility of conservative treatment during acute hemorrhage; (2) elective surgical treatment may be undergo without a mandatory step of large portal descompression. The Author only indicate surgical treatment in patients with hemorrhage antecedence and his preference consist in splenectomy plus obliterative suture of the varices at the "vulnerable zone" and when possible, ligature of left gastric vein also; 358 patients were undergone surgery with operative mortality 3.07%, 347 were followed during 1 to 25 years; late mortality 8.38%; recurrence hemorrage 11.58%; none porto-sustemic encephalopaty was observed.

Detection of the acute phase of abdominal angiostrongyliasis with a parasite-specific IgG enzyme linked immunosorbent assay

Angiostrongylus costaricensis may cause intestinal lesions of varied severity when it accidentally infects man in Central and South America. First-stage larvae have never been detected in stools. Therefore, a parasite-specific IgG ELISA was evaluated for the determination of the acute phase of infection. The specificity and the sensitivity of the immunoassay was shown to be 76.2% and 91.1%, respectively. Eight serum samples taken from patients with histopathological diagnosis, at different time points (3 to 15 months) after surgical treatment, showed a sharp and early decline in antibody reactivity. The titration of anti-A. costaricensis antibodies has proved to be a useful method for the diagnosis of acute abdominal angiostrongyliasis.

Imaging techniques and histology in the evaluation of liver fibrosis in hepatosplenic schistosomiasis mansoni in Brazil: a comparative study

Few publications have compared ultrasound (US) to histology in diagnosing schistosomiasis-induced liver fibrosis (LF); none has used magnetic resonance (MR). The aim of this study was to evaluate schistosomal LF using these three methods. Fourteen patients with hepatosplenic schistosomiasis admitted to hospital for surgical treatment of variceal bleeding were investigated. They were submitted to upper digestive endoscopy, US, MR and wedge liver biopsy. The World Health Organization protocol for US in schistosomiasis was used. Hepatic fibrosis was classified as absent, slight, moderate or intense. Histology and MR confirmed Symmers' fibrosis in all cases. US failed to detect it in one patient. Moderate agreement was found comparing US to MR; poor agreement was found when US or MR were compared to histology. Re-classifying LF as only slight or intense created moderate agreement between imaging techniques and histology. Histomorphometry did not separate slight from intense LF. Two patients with advanced hepatosplenic schistosomiasis presented slight LF. Our data suggest that the presence of the characteristic periportal fibrosis, diagnosed by US, MR or histology, associated with a sign of portal hypertension, defines the severity of the disease. We conclude that imaging techniques are reliable to define the presence of LF but fail in grading its intensity.

The decision of an obese woman to have bariatric surgery: the social phenomenology

Objective To understand the process by which an obese woman decides to have bariatric surgery. Method A qualitative survey with a social phenomenology approach, carried out in 2012, with 12 women, using the phenomenological interview. Results A woman bases the decision to have the surgery on: the inappropriateness of her eating habits; a physical appearance that is incompatible with an appearance that is standardized by society; the social prejudice that she has to live with; the limitations imposed by obesity; and her lack of success with previous attempts to lose weight. Outcomes that she hopes for from the decision to have the surgery include: restoring her health; achieving social inclusion; and entering the labor market. Conclusion This study allows one to reflect that prescriptive actions do not give a satisfactory response to a complexity of the subjective questions involved in the decision to have surgery for obesity. For this, what is called for is a program of work based on an interdisciplinary approach, and training that gives value to the bio-psycho-social aspects involved in a decision in favor of surgical treatment.

Glenohumeral interposition of rotator cuff stumps: a rare complication of traumatic rotator cuff tear

Abstract The present report describes a case where typical findings of traumatic glenohumeral interposition of rotator cuff stumps were surgically confirmed. This condition is a rare complication of shoulder trauma. Generally, it occurs in high-energy trauma, frequently in association with glenohumeral joint dislocation. Radiography demonstrated increased joint space, internal rotation of the humerus and coracoid process fracture. In addition to the mentioned findings, magnetic resonance imaging showed massive rotator cuff tear with interposition of the supraspinatus, infraspinatus and subscapularis stumps within the glenohumeral joint. Surgical treatment was performed confirming the injury and the rotator cuff stumps interposition. It is important that radiologists and orthopedic surgeons become familiar with this entity which, because of its rarity, might be neglected in cases of shoulder trauma.

Cisto esplênico não-parasitário e não-neoplásico

The authors present a rare case of pathology from spleen, a nonparasitic, non-neoplastic splenic cyst, in an adult male patient without a previous history of abdominal trauma. Principal clinical findings were pain in left upper quadrant, nausea, regurgitation and precocious satiation. On investigation, ultrasonography and CT scan showed an expansive lesion in the spleen, compressing the stomach. Surgical procedure was splenectomy and a microscopical examination revealed a non- parasitic, non-neoplastic splenic cyst. Splenic cysts are usually benigns, but surgical remotion is necessary when they are symptomatic or exist risk of rupture. In this report is presented the classification of splenic cysts, clinical manifestations, diagnostics methods and discussed their surgical treatment.

Neurofibrossarcoma associado a neurofibromatose

The clinical and pathological aspects of neurofibromatosis are summarized and an updated pathogeny of the tumor is made. The malignancy of the NFS senns to be linled to the NF - 1 gene mutations, with loss of the suppressor gene in the chromosone 17 pl. The surgical treatment is always useful because it lowers the pressure and relieves the patient.

Quilotórax traumático por ferimento penetrante do tórax

The authors report two cases of traumatic chylothorax. They were caused by gunshot wounds producing thorax transfixing injuries and lhe chilothorax was subsequently diagnosed during lhe thoracic drainage follow-up, a chilous colar was noticed in lhe drainage output. This was confirmed with a Sudam 111 stain. Both cases were treated conservatively with Total Parenteral Nutrition according to the current literature. One of the cases, in its evolution, required surgical treatment due to a persistent high output fistulae.

Fistula gastrocólica

A case of gastrocolic fistula(GCF) in a patient with duodenal stenosis who had previously undergone gastroenteric anastomosis is reported. The patient went through hemigastrectomy, partial colectomy and segmental enterectomy with bloc resection. Reconstruction was carried out through Billroth II gastrojejunostomy, jejunojejunostomy and end-to-end anastomosis of the colon. The patient had good post-operative evolution and was discharged from hospital seven days after surgery. GCF should be suspected in patients presenting weight loss, diarrhea and fecal vomiting, mainly with history of peptic ulcer surgery, gastric or colonic malignancy and use of steroidal and nonsteroidal antiinflamatory drugs. Barium enema is the choice test for diagnosis, however, the benign or malignant nature of the lesion should always be evaluated through high digestive endoscopy. Clinical treatment with oral H2-antagonists and discontinuing ulcerogenic medications might be indicated in some cases; surgical treatment is indicated in cases of malignant disease and might be indicated in cases of peptic disease as it treats GCF and also the baseline disease. Some advise upwards colostomy at first. The most used technique is bloc resection, including the fistulous tract, hemigastrectomy and partial colectomy. Gastrectomy, fistulous tract excision and colon suturing may be performed in some cases. The mortality rate is related to metabolic disorders and the recurrence with the use of antiinflammatory drugs.

Diverticulo epifrênico do esôfago

Disphagia is a very common complaint among patients seeking a gastroenterologists. Esophageal motility disorder is a frequent finding, at times associated with pulsion diverticula. We present a case of a 68 year old female patient with thoracic pain and double epiphrenic diverticula. The upper gastrointestinal tract examination revealed two epiphrenic diverticula, one with 6-7 cm and the other measuring 2 cm, located 30 cm from the dental arcade. She underwent surgical treatment to remove the larger diverticula, a long esophageal myotomy and a Belsey-Mark IV antireflux technique. She presented an uneventful recovery and is doing well I8 months following surgery.

Trauma abdominal penetrante consecutivo à corrente elétrica industrial

The authors present a case report of a victim of high power electric shock. The main electric lesion was a penetrating abdominal wound with loss of substance of the abdominal wall and an electric lesion of the hepatic segment and of the gallbladder. The surgical treatment included hepatic segmentectomy, cholecystectomy, repair of the abdominal wall with Marlex prosthesis and skin graft, besides the debridment of the lesions of extremities. The postoperative evolution was satisfactory and the follow-up for 6 months didn't show any sequelae.

Tumor carcinóide do reto

The rectum is the second most common location of the carcinoid tumors of the gastrointestinal tract. It represents approximately one or two per cent of the rectal neoplasms. Metastases are less frequent and it presents a better prognosis than carcinoid tumors found in the digestive tract. Treatment is surgical and the technique to be used depends fundamentally on the size of the tumor and the degree of in the intestinal wall penetration. Lesions which are greater than one centimeter have been treated with local excision, while the ones greater than two centimeters have been submitted to a radical resection. This article presents a case of rectal carcinoid diagnosed and treated initially as adenocarcinoma by abdominal rectossigmoidectomy. There were no signs of recurrence after a period of five years and six months of post-surgical follow-up. Nowadays the validity of radical resection in the treatment of rectal carcinoids has been much questioned due to the fact that it has not shown a significant raise in survival rate when compared with patients who were submitted to a local resection.

Derivação biliopancreática com preservação gástrica videolaparoscópica: sistematização técnica

BACKGROUND: The authors describe a videolaparoscopic technical variation of biliopancreatic diversion, and its rationale, as well as its preliminary results.They operated on 12 female patients, age between 26 and 49 years, BMI range 47,4 and 59,5kg/m². There were no intraoperative complications; operative time ranged from 2 to 4,5 hours; discharge in the 3rd. postoperative day. Liquid dietetic recommendations in the early period, and normal diet after the first week. One patient was readmmitted after 1 week with abdominal pain because of excessive ingestion of food; there was deep venous trombosis in one patient. Follow-up showed loss of excess weight of 27,4% after four months. Initial results of the described operation sugests it may be a good alternative to morbid obesity surgical treatment; it is strongly required a multidisciplinar pre and postoperative treatment program.
