Hemophilia B acquired after cadaveric liver transplantation: a case report.

Hemophilia B is a recessive hereditary disease, and manifestations result from coagulation factor IX deficiency. Although improbable, as factor IX is produced exclusively in the liver, the possibility of developing the disease after transplantation represents an infrequent but potentially morbid complication. Standard laboratory tests may be insufficient to determine the probability of transmission of this pathology. This report describes the case of a patient who developed hemophilia B after liver transplantation whose donor had no prior knowledge of the disease.

Quality of Life after 10 Years of Liver Transplantation.

AIM: This study goal was to evaluate the long-term quality of life of patients who underwent cadaveric liver transplants (CLT) in two Brazilian hospitals. METHODS: Medical records of all patients who underwent CLT and survived over 10 years were revised. The international validated questionnaire Short-Form 36 was employed to assess the quality of life. Patients data were obtained from electronic medical records and study protocols. RESULTS: A total of 342 patients underwent CLT, of which 129 were alive and 93 fully answered the questionnaire and were included in the study. The group consisted of 62 men (66.6%) and 31 women (33.4%), with average age of 40.1±15.9 years. Follow-up time was 16±4.1 years. The most common indication of CLT was hepatic cirrhosis caused by hepatitis C virus, 24.7%. Transplanted patients had lower scores than the general population in mental health [62.9 (95%CI: 60.1-65.7,) vs. 74.5, p < 0.001]. In all other domains, transplanted patients had similar (emotional aspect limitiation, pain, and general health status) or superior (physical aspect limitation, social aspects, functional capacity, and vitality) scores than the general population. Functional capacity score was lower in patients with long-term complications, who were aged more than 50-years, and unemployed. CONCLUSIONS: The quality of life in patients with more than 10 years after CLT was similar or superior than the general population, except for the mental health domain.

Hepatectomy and intrahepatic hepaticocutaneous jejunostomy for bilateral primary hepatolithiasis: Case report.

INTRODUCTION: Primary hepatolithiasis is a rare disease in western countries and it is associated with repeated attacks of acute cholangitis. Without proper treatment, hepatolithiasis can lead to progressive biliary strictures and secondary biliary cirrhosis. PRESENTATION OF CASE: A 40 years old male was admitted due to recurrent cholangitis during the last 18 years. Bilateral primary hepatolithiasis was diagnosed and treated by left hepatectomy with an intrahepatic hepaticocutaneous jejunostomy. There were no postoperative complications and the patient was discharged after 7 days. DISCUSSION: The management of patients with primary hepatolithiasis remains a challenging task due to the high incidence of residual and recurrent stones after treatment. CONCLUSION: Primary bilateral hepatolithiasis is a complex disease that can be managed with partial hepatectomy with an intrahepatic hepaticocutaneous jejunostomy.

Results of laparoscopic cholecystectomy in the elderly. / Resultado da colecistectomia laparoscópica em idosos.

OBJECTIVE: to evaluate the results of laparoscopic cholecystectomy in the elderly compared with younger patients. METHODS: we retrospectively reviewed computerized medical records of all patients who underwent laparoscopic cholecystectomy for chronic or acute cholecystitis from January 1, 2011 to March 31, 2018 at a single teaching hospital. We stratified the patients into two groups: elderly (≥60 years of age) and younger (<60 years of age). RESULTS: of 1,645 patients subjected to laparoscopic cholecystectomy, 1,161 (70.3%) were younger and 484 (29.7%) were elderly. The rate of male was higher in the elderly (n=185; 38.2%) group than in the younger (n=355; 30.6) (p=0.003). Jaundice was more common in the elderly (p=0.004). The rate of prior abdominal operation was also higher in the elderly (p<0.001). The percentage of patients with ASA score II, III, and IV was higher in the elderly group (p<0.001 in score II and III and 0.294 in score IV). Operative time was longer in the elderly (71.68±31.27) than in the younger group (p=0.001). The following perioperative data were higher in the elderly: acute cholecystitis (p<0.001), conversion rate (p=0.028), postoperative complications (p=0.042), and mortality (p=0.026). CONCLUSION: the operative time is longer and the rate of acute cholecystitis, conversion to open cholecystectomy and postoperative complications are higher in the elderly patients submitted to laparoscopic cholecystectomy when compared with younger individuals.

Neuroendocrine regulation of energy balance: Implications on the development and surgical treatment of obesity.

INTRODUCTION: Obesity, a serious public health problem, occurs mainly when food consumption exceeds energy expenditure. Therefore, energy balance depends on the regulation of the hunger-satiety mechanism, which involves interconnection of the central nervous system and peripheral signals from the adipose tissue, pancreas and gastrointestinal tract, generating responses in short-term food intake and long-term energy balance. Increased body fat alters the gut- and adipose-tissue-derived hormone signaling, which promotes modifications in appetite-regulating hormones, decreasing satiety and increasing hunger senses. With the failure of conventional weight loss interventions (dietary treatment, exercise, drugs and lifestyle modifications), bariatric surgeries are well-accepted tools for the treatment of severe obesity, with long-term and sustained weight loss. Bariatric surgeries may cause weight loss due to restriction/malabsorption of nutrients from the anatomical alteration of the gastrointestinal tract that decreases energy intake, but also by other physiological factors associated with better results of the surgical procedure. OBJECTIVE: This review discusses the neuroendocrine regulation of energy balance, with description of the predominant hormones and peptides involved in the control of energy balance in obesity and all currently available bariatric surgeries. CONCLUSIONS: According to the findings of our review, bariatric surgeries promote effective and sustained weight loss not only by reducing calorie intake, but also by precipitating changes in appetite control, satiation and satiety, and physiological changes in gut-, neuro- and adipose-tissue-derived hormone signaling.

BAROS METHOD CRITICAL ANALYSIS(BARIATRIC ANALYSIS AND REPORTING SYSTEM).

INTRODUCTION: Although it has received several criticisms, which is considered to be the most effective method used for global assessment of morbid obesity surgical treatment, still needs to be updated. OBJECTIVE: Critical analysis of BAROS constitution and method. METHOD: BAROS as headings was searched in literature review using data from the main bariatric surgery journals until 2009. RESULTS: Where found and assessed 121 papers containing criticisms on BAROS constitution and methodology. It has some failures and few researches show results on the use of this instrument, although it is still considered a standard method. Several authors that used it found imperfections in its methodology and suggested some changes addressed to improving its acceptance, showing the need of developing new methods to qualify the bariatric surgery results. CONCLUSION: BAROS constitution has failures and its methodology needs to be updated.

Duodenal-jejunal bypass surgery enhances glucose tolerance and beta-cell function in Western diet obese rats.

BACKGROUND: The aim of this study was to investigate the effect of the duodenal-jejunal bypass (DJB) on glucose homeostasis and islet insulin secretion in Western diet (WD) obese rats. METHODS: Male Wistar rats received a standard rodent chow diet (CTL group) or WD ad libitum. After 32 weeks of diet, WD rats were submitted to duodenal-jejunal bypass (WD DJB) or sham (WD S-DJB) operation. Intraperitoneal (ip) glucose tolerance test was performed 1 week after surgery. Body weight, fat pad depots, glycemia, insulinemia, HOMA-IR, and glucose-induced insulin secretion were evaluated 1 month after surgery. RESULTS: Body weight and fat pads of the WD group were higher than those of the CTL group. Sham and DJB surgeries did not alter these parameters. WD and WD S-DJB rats were glucose intolerant, insulin resistant, and hyperinsulinemic. WD DJB rats showed similar glucose tolerance, insulin sensitivity, and plasma insulin levels to those of CTL rats. WD rats presented higher fat and glycogen contents in the liver. DJB surgery normalized fat and glycogen stores in the liver of the WD DJB group. Insulin release at 11.1-mM glucose, in isolated islets from WD and WD S-DJB rats, was higher than from islets of CTL rats. In contrast, DJB surgery improves the beta-cell secretory capacity with increased glucose-induced secretion at 5.6-, 11.1-, and 22.2-mM glucose in WD DJB islets, compared with CTL islets. CONCLUSIONS: DJB surgery improves glucose homeostasis and enhances beta-cell glucose responsiveness in rats submitted to the WD diet without any modification in adiposity.

[Laparoscopic cholecystectomy in transplant patients]. / Colecistectomia laparoscópica em transplantados.

OBJECTIVE: This study reviews our experience with laparoscopic cholecystectomy in the treatment of cholelithiasis in transplant patients. METHODS: Demographic data, medications used, and operative and postoperative data of all transplant recipients who were subjected to laparoscopic cholecystectomy for cholelithiasis at our hospital were obtained. RESULTS: A total of 15 transplant patients (13 renal transplantation and 2 bone marrow transplantation) underwent laparoscopic cholecystectomy. All patients were admitted to the hospital on the day of the operation. The immunosuppressive regimen was not modified during hospitalization. Clinical presentation of cholelithiasis was biliary colicky (n=12), acute cholecystitis (n=2), and jaundice (n=1). The operation was uneventful in all patients. Postoperative complications were nausea and vomiting in 2 patients, prolonged tracheal intubation in 1, wound infection in 1 and large superficial hematoma in 1 patient. CONCLUSION: Laparoscopic cholecystectomy is associated to a low morbidity and mortality and good postoperative outcome in transplant patients with uncomplicated cholecystitis.

The impact of bariatric surgery on nonalcoholic fatty liver disease.

PURPOSE OF REVIEW: To analyze the effects of bariatric surgery on nonalcoholic fatty liver disease by reviewing the most important and recent studies. RECENT FINDINGS: The prevalence of obesity has increased dramatically over the last decades. Comorbidities related to obesity, such as nonalcoholic fatty liver disease are also increasing. Nonalcoholic fatty liver disease is a progressive disease with potential evolution to liver cirrhosis and hepatocellular carcinoma. Overweight patients who have nonalcoholic fatty liver disease should be considered for a weight loss program; however, long-term result with dietary interventions and drug therapy has been disappointing. Bariatric surgery is effective in promoting long-term weight loss in morbidly obese patients with control of comorbidities, especially those associated with the metabolic syndrome. On the basis of the early experience with extensive intestinal bypass, it was believed that rapid weight loss could cause liver damage. In contrast, recent prospective and retrospective observational studies and case series have demonstrated that bariatric surgery is well tolerated and is associated with nonalcoholic fatty liver disease regression in a significant number of patients. SUMMARY: There is good level of evidence that bariatric surgery is associated with nonalcoholic fatty liver disease regression in morbidly obese patients.

[Opinion and knowledge of the population of a Brazilian city about organ donation and transplantation]. / Opinião e conhecimento da população da cidade de curitiba sobre doação e transplante de órgãos.

OBJECTIVE: To determine the opinion and knowledge of the population of Curitiba about organ donation and transplantation. METHODS: The opinion and knowledge about organ donation and transplantation of 1,000 subjects over 18 years of age were determined. The subjects responded to a questionnaire of 20 queries. Respondents had age, gender, social-economic, and education distributions similar to those of the Brazilian population, as defined by the Brazilian Institute of Geography and Statistics (IBGE). RESULTS: Eighty-seven percent of respondents were in favor of organ donation. There was no difference in the percentage of respondents in favor of donation in relation to gender, marital status, religion, and income. The main reasons in favor of donation were to save life, to help other persons and to donate life. The main reasons against donation were distrust towards medicine or the Brazilian transplantation organization, the existence of organ sale, and fear of body mutilation. Most respondents believed that wealthy people have a better chance to receive an organ than poor people, that sales of organs exists in Brazil, and that misdiagnosis of brain death may occur. CONCLUSION: Most respondents are in favor of organ donation and have a good knowledge of organ donation and transplantation. The majority distrusts Brazilian organization of organ distribution and brain death diagnosis.

[Effect of watery extract of Orbignya phalerata (babassu) in the gastric healing in rats: morphological and tensiometric study]. / Efeito do extrato aquoso de Orbignya phalerata (babaçu) na cicatrização do estômago em ratos: estudo morfológico e tensiométrico.

INTRODUCTION: The large use of plants in the prevention and treatment of different diseases is a milenar practice. In Brazil due to it's rich flora there is a huge material for research and use in popular medicine. The babassu (Orbignya phalerata) is a native tree from North of the Brazil and has a high concentration at the State of Maranhão. The powder of it's mesocarp is known as amid, and has been used as meal and medication due to the known activity against antiinflammatory reaction, pain, pyrexia and immunomodulation. PURPOSE: To analyze the effect of mesocarp of Orbignya phalerata (babassu) in gastric wound healing in rats under morphologic and tensiometric aspects. METHOD: Forty Wistar rats, male, adults were submitted to a longitudinal incision of 1 cm in the gastric body and sutured with separated stitches of polypropylene 6.0. After this common procedure the animals were allocated in the aleatory way in two groups Orbignya (GO) and Control (GC) with 20 animals each one. In the GO was used intraperitoneal doses of 50 mg/kh of Orbignya phalerata extract and in the GC water 1 ml/kg. Each group was divided in two subgroups of ten rats according to the period of death, at 3rd and 7th post-operative days. After the death, the abdominal cavity was evaluated and the stomach withdrawn. For the comparative analysis between the groups the macroscopic and histological parameters of wound healing were utilized. RESULTS: There were no abscess, fistulae and haematom in the animals of the study. Abdominal adhesions were observed in both groups of the animals at 3rd and 7th post-operative days. Dehiscence of the gastrography was identified in one 3rd day rat of subgroups GO. The resistance to air insufflation was higher in GO 3rd day (p=0.087). The analysis of histological parameters showed statistical difference related to wound coaptation in favor to subgroup GO 7th post-operative day. CONCLUSIONS: The extract of mesocarp of Orbignya phalerata in dose and path utilized positively interfered on the gastrography when compared with control group in animals at 7th post-operative day.

[Schinus terebinthifolius Raddi and it's influence in the healing process of colonic anastomosis: experimental study in rats]. / Efeito do extrato hidroalcoólico de Aroeira (Schinus terebinthifolius Raddi) na cicatrização de anastomoses colônicas: estudo experimental em ratos.

INTRODUCTION: The healing is a complex biological event that involves inflammation, chemotaxis, cells proliferation, differentiation and remodeling. In Brazilian popular medicine, the "Aroeira" is used to treat different situations The anastomotic healing is always a preoccupation among surgeons. The fail in intestinal anastomosis leads to fistulas and dehiscences. PURPOSE: To evaluate the effect of the hydroalcoholic extract of Schinus terebinthifolius Raddi (Brazilian pepper tree) in the healing of colonic anastomosis. METHODS: Forty Wistar rats were randomly divided in two groups (Aroeira and control), each one with 20 animals, according to the treatment received after the anastomosis (Aroeira extract or saline solution 0,9%) and each group was divided in two subgroups (C3 and C7 and A3 and A7,) according to the euthanasia day (at 3rd and at 7th). The macroscopic, microscopic and bursting pressure measurements were performed. To evaluate the groups, the non-parametric test of Mann-Whitney was applied. RESULTS: In the macroscopic aspects, there was no significant difference between the Aroeira and the control group, both at the 3rd and the 7th days. When compared the subgroups of microscopic analysis at the 3rd day, the difference between the Aroeira and the control group was significant in the variables congestion (p = 0.005), polymorphonuclears (p = 0.034), mononuclears (p = 0.023), fibroblastic proliferation (p = 0.023) and at the healing stage (p = 0.001). At the 7th day analysis, the difference between the Aroeira and the control group was significant in all the variables of microscopic analysis. No significant differences were found in the bursting pressure. CONCLUSION: It was observed a favorable effect of Aroeira, at microscopic level, in the healing process of colonic anastomosis.

[Effects of Jatropha gossypiifolia L. (bellyache bush) extract on the healing process of colonic anastomosis: experimental study in rats]. / Ação do extrato de Jatropha gossypiifolia L. (pião roxo) na cicatrização de anastomose colônica: estudo experimental em ratos.

INTRODUCTION: Phytotherapy has been drawing interest from the scientific community regarding its potential wound healing properties. There are few studies available that present a correct scientific methodology and, therefore, phytotherapy remains an open field for further research. PURPOSE: To evaluate the effects of Jatropha gossypiifolia L. (bellyache bush) on the healing of colonic anastomosis in rats. METHODS: Forty Wistar rats were subjected to a complete section of the colon, that was soon sutured with eight separate stitches using monofilament polypropylene 6-0. Randomly, the animals were divided into control group (CG), with 20 rats, which were injected with 0.9% sodium chloride solution intraperitoneally (1 mL/kg) and Jatropha group (JG), also with 20 rats, which were injected with Jatropha gossypiifolia L. alcoholic extract intraperitoneally (1 mL/kg). Each of the groups was subdivided into two subgroups of ten rats, according to the sacrifice date, third and seventh days (CG3/ CG7 and JG3/ JG7). After sacrifice, the segment of the colon containing 1cm proximal and distal to the site of anastomosis was removed and subjected to the pressure test with air insulation. This segment was then opened and a 1.0 x 0.5 cm part was removed and placed under 10% formaldehyde for histological analysis with hematoxylin-eosin and Masson's trichrome stainings. RESULTS: The evaluation of the pressure rupture test demonstrated statistical significance regarding the sacrifice date. On the third day, the average pressure of the CG (25.4 mmHg) and the JG (76.4 mmHg) revealed p = 0.013, and on the seventh day, the average pressure of the CG (187,3 mmHg.) and the JG (135.1 mmHg.) revealed p = 0.014. When assessing the microscopic variables among the groups of the 3rd day, only the variables edema and polymorphonuclear cells did not show statistical differences. On the 7th day, all of the variables assessed demonstrated significant differences. CONCLUSIONS: Regarding mechanical resistance, there was a difference in resistance between the JG3 and the CG3, and a shift of resistance when comparing the JG7 and CG7, which suggests a weakening of the Jatropha effect at a later stage of healing. The histological evaluation revealed an improvement of the acute inflammatory process in the JG3 when compared to the CG3, which was even more intense during the chronic stage, when the two groups are compared on the seventh day. The histological study of the inflammatory process, in general, showed a favorable effect to the Jatropha group compared to the control group.

[Donor quality of life after living donor liver transplantation]. / Qualidade de vida do doador após transplante hepático intervivos.

BACKGROUND: Quality of life of the donor after living donor liver transplantation has not been evaluated in Brazil yet. AIM: To evaluate the quality of live of the donor after living donor liver transplantation. METHODS: Of a total of 300 liver transplantations, 51 were of living donors. All donors with less than 6 months of follow-up and those who did not want to participate were excluded from the study. The donors answered a questionnaire contained 28 questions about several aspects of donation. Demographic and clinical data from the donors were also evaluated. RESULTS: Thirty-seven donors were included in the study. Thirty-two were first or second degree relatives of the receptor. Only one donor would not donate again. Twenty-two donors (59%) experienced more postoperative pain than they had previously anticipated. Return to regular activities occurred in less than 3 months for 21 donors (57%). Twenty-one donors (57%) referred financial loss with the donation due to expenses with medications, exams, transportation or lost wages. Thirty-three (89%) had no modification or limitation in their lives after donation. The most negative aspects of donation were postoperative pain and the presence of a surgical scar. Most postoperative complications resolved with clinical treatment, but severe or potentially fatal complications occurred in two patients. CONCLUSIONS: Most donors had good recovery and returned to regular activities few months after donation. The most negative aspect of donation was postoperative pain.
