[Cripples at the medieval hospital of Bátmonostor, Hungary--archeological findings].

Cripples from the medieval hospital of Bátmonostor, Hungary. People with disabilities were generally burdened with a painful fate in ancient times, however in the hospitals was no effective therapy. The hospital of Batmonostor was founded at late 13th century, The authors examine by morphological, radiological and histological methods 426 complete skeletons excavated from medieval (14th-15th century) cemetery of Bátmonostor (Hungary). Among them 30 cases (7.1%) of bony ankylosis, (24 cases on lower limb and 6 cases on upper limb) was found. Sacroiliac ankylosis 3 cases, Bechterew's spondylitis ankylopoetica 1 case was seen. Spondylitis tuberculosa and malum Potti 4 cases, and hunchback with other aetiology 2 cases was detected. Beside the cases with ankylosis severe posttraumatic osteomyelitis (7 cases), primary malignant bone tumors (2 cases) and an osteoplastic metastatic tumors (probably prostata carcinoma) was diagnosed. Paleopathologic study of the physically disabled may yield information and insight on the prevalence of crippling disorders. The authors hypothetize, that crippled persons lived in the hospital until their deaths.

Prospective randomised comparison of organ-preserving pancreatic head resection with pylorus-preserving pancreaticoduodenectomy.

BACKGROUND AND AIMS: In a prospective, randomised, control trial organ-preserving pancreatic head resection (OPPHR) was compared with pylorus-preserving pancreaticoduodenectomy (PPPD) to assess the advantages and disadvantages of each type of operation. PATIENTS AND METHODS: Forty patients were allocated randomly to either the OPPHR (n=20) or the PPPD (n=20) group. The surgical data, postoperative complications, induction of diabetes mellitus, postoperative pain and quality of life 1 year, postoperatively, were considered. RESULTS: The two study groups of 20 patients were well balanced with regard to sex, age, chronic pancreatitis history and indication for surgery. The duration of the operation for OPPHR and PPPD was 142.5+/-4.9 and 278+/-6.9 min, respectively (P<0.05). The postoperative mortality in each group was zero. After OPPHR and PPPD, the morbidity was 0 and 40%, respectively (P<0.05). The duration of hospital stay was also significantly different: 8.05+/-0.9 vs 13.8+/-3.9 days (P<0.05). After 1 year the pain relief was effective in both groups, but three patients acquired diabetes mellitus after PPPD; the body weight had increased by 7.8+/-0.9 and 3.2+/-0.3 kg after OPPHR and PPPD, respectively (P<0.05). CONCLUSION: The two procedures are equally safe and effective with regard to pain relief, but OPPHR is superior to PPPD not only in the operation data and morbidity, but also in the quality of life 1 year postoperatively. OPPHR should be regarded as a recommended procedure in the treatment of chronic pancreatitis.

Surgical management and complex treatment of infected pancreatic necrosis: 18-year experience at a single center.

Infected pancreatic necrosis (IPN), the most severe form of acute pancreatitis, is responsible for most cases of pancreatitis-related morbidity and mortality. Since 1986, 220 patients with IPN have been treated. The surgical treatment was performed on average 18.5 days (range, 8-25 days) after the onset of acute pancreatitis and consisted of wide-ranging necrosectomy, combined with widespread drainage and continuous lavage. In 108 of the 220 cases, some other surgical intervention (distal pancreatic resection, splenectomy, total pancreatectomy, cholecystectomy, colon resection, etc.) was also performed. Following surgery, the supportive therapy consisted of immunonutrition (glutamine and arginine supplementation) and modification of cytokine production with pentoxifylline and dexamethasone. Continuous lavage was applied for an average of 44.5 days (range, 21-95 days), with an average of 9.5 L (range, 5-20 L) of saline per day. The bacteriologic findings revealed mainly enteral bacteria, but Candida infection was also frequently detected (21%). Forty-eight patients (22%) had to undergo reoperation. The overall hospital mortality was 7.7% (17 patients died). In our experience, IPN responds well to adequate surgical treatment, continuous, longstanding widespread drainage and lavage, together with supportive therapy consisting of immunonutrition and modification of cytokine production, combined with adequate antibiotic and antifungal medication.

Necrolytic migratory erythema.

BACKGROUND: Necrolytic migratory erythema is considered to be a paraneoplastic dermatosis. The classical symptoms are associated with alpha-cell pancreatic islet cell tumor or 'glucagonoma'. Generally, extracutaneous hallmarks of this disease include weight loss, diabetes, anaemia and diarrhoea. OBSERVATION: We report a case of a 39-year-old woman with a 3-year history of recalcitrant psoriasiform eruption, who had no other associated symptoms on routine examination. Histologic examinations suggested necrolytic migratory erythema. Abdominal computer tomography was performed, which revealed a tumor in the tail of the pancreas. After distal resection of the pancreas her skin symptoms resolved in a few days time. Histology was consistent with glucagonoma. She is clinically well and symptomless and no signs of metastasis after 4 years. CONCLUSIONS: It is infrequent to have only necrolytic migratory erythema, hyperglucagonaemia and islet-cell tumor but no other extracutaneous symptoms in glucagonoma syndrome. To our knowledge, ours is the second such case reported in the literature. Skin symptoms are important, often they are the clue to the diagnosis of glucagonoma syndrome.

Polymorphism of the TNF-alpha, HSP70-2, and CD14 genes increases susceptibility to severe acute pancreatitis.

OBJECTIVES: Proinflammatory cytokines and heat shock proteins play fundamental roles in the pathogenesis of acute pancreatitis. We studied whether polymorphisms of the tumor necrosis factor alpha (TNF-alpha), heat shock protein 70-2 (HSP70-2), and CD14 genes correlate with the severity of acute pancreatitis. METHODS: Patients with acute pancreatitis (n = 77) of mixed etiology were grouped according to the severity of the disease on the basis of the Ranson scores. Healthy blood donors (n = 71) served as controls. TNF-alpha-308 polymorphism was determined by NcoI RFLP, HSP70-2 polymorphism by PstI RFLP, and CD14-159 polymorphism by melting point analysis. RESULTS: There was a moderate increase in the frequency of the TNF1/2 genotype (P = 0.046) among patients with severe acute pancreatitis as compared with those with mild disease. A more significant increase was observed in the frequency of the HSP70-2 G allele between groups of patients with mild or severe pancreatitis (18.9% vs. 53%; P < 0.001). Conversely, the A/A genotype was markedly more frequent among the patients with mild pancreatitis (P < 0.0001). There was no significant correlation between CD14-159 promoter polymorphism and the severity of pancreatitis. CONCLUSION: High frequencies of the HSP70-2 G and the TNF-alpha -308 A alleles were associated with risk of severe acute pancreatitis. Genotype assessments may be important prognostic tools to predict disease severity and the course of acute pancreatitis. Therefore, genotype assessments may also be used to guide treatment or to identify risk populations for severe acute pancreatitis.

Safe closure technique for distal pancreatic resection.

BACKGROUND AND AIMS: Various methods had previously been employed to manage the proximal pancreas after distal resection (mattress sutures with duct ligation; pancreato-enterostomy or stapling with stainless steel staples, etc.), with postoperative complications in 13% (6%-30%) of the cases, on average. In our practice, to reduce these complications, we applied staples made from Polysorb (Auto Suture), an absorbable lactomer. PATIENTS/METHODS: In the past 10 years, distal pancreatic resection in 90 patients [62 men, 28 women, mean age 52 (24-72)] years) was followed by closure of the resection surfaces with absorbable lactomer clips. Indications for distal resection (with or without splenectomy) were: focal pancreatic necrosis, spontaneous pancreatic fistulas, abscess, pseudocyst, traumatic disruption, segmental chronic obstructive pancreatitis in the tail, and benign (cystadenoma, or insulinoma) or malignant tumours. RESULTS: The postoperative period was uneventful in all these patients, without any complications (pancreatic fistula, abscess or bleeding). No morbidity or mortality occurred in the follow-up period (6 or 12 months postoperatively) with the exception of one patient who suffered a pseudocyst 6 months after surgery and was treated by cysto-jejunostomy. CONCLUSIONS: The clinical results clearly demonstrated that the application of absorbable lactomer staples for closure of the transected margin of the pancreas is a safe alternative to the standard closure technique. These staples can be applied in all cases when distal pancreatic resection is indicated for benign or malignant disorders or a traumatically injured pancreatic gland.

[Surgical treatment of neuroendocrine tumours of the pancreas].

Gastro-entero-pancreatic (GEP) endocrine tumours can originate from various pancreatic islet cells, from endocrine cells of the gastric and duodenal mucosa, or from APUD cells of neuroectodermal origin in the gastrointestinal tract. They are benign when smaller than 2 cm, but larger tumours are generally malignant. Surgery is the only method for the curative treatment of GEP tumours. A diagnosed and localised tumour is an absolute indication for radical surgery. Conservative medical treatment may be indicated only in an inoperable condition, but in this case tumour reduction surgery is suggested. In the last 15 years 22 patients with pancreatic neuroendocrine tumours were treated without any mortality. Except for two of them, the surgical therapy was curative.

[Results of surgical treatment of pancreatic cancer].

UNLABELLED: The aim of this study was to assess the results of the treatment of (255) patients with pancreatic cancer in the Department of Surgery, University of Szeged, during the time period 1997-2001. METHODS: The age, male/female ratio, postoperative morbidity and mortality were discussed. RESULTS: The resecability rate was 17.3% (44/255 patients). The mortality rate was 2.3% (1/44 patients) after radical operations and 12.1% (15/124 patients) after the palliative procedures. Localization and UICC staging after pancreatic tumors were analyzed. CONCLUSIONS: In spite of the improvement of the new diagnostic methods, the proportion of patients undergoing radical surgery has not been increased in this period. Palliative surgical procedures are indicated in the case of advanced tumor stage. Choledochojejunostomy with Roux-Y loop offers the best results for the treatment of biliary obstruction. The role of endoscopic stenting is very questionable and the increased rate of postoperative biliary infections indicates that this procedure should be avoided in the preoperative treatment of patients who are suitable for potentially curative operation.

[Surgical and endoscopic management of bile duct cancer].

UNLABELLED: There is still considerable controversy regarding the value of surgical versus nonsurgical treatment for bile duct cancer. Therapeutic modalities vary from total hepatectomy and liver transplantation to percutaneous or endoscopic stent insertion. The aim of this study was to assess the results of the treatment of 118 patients presented with bile duct cancer in the Department of Surgery, University of Szeged, during the time period 1990-2002. METHODS: The age, male/female ratio, postoperative morbidity and mortality were analyzed. RESULTS: The resectability rate was 18% (21/118). The mortality rate was 23.8% (5/21) after radical operations and 7% or 12.5% after the palliative procedures. 67 patients had palliative surgery following unsuccessful or recurrent jaundice after non-surgical palliation. The previously applied palliative methods have been transpapillary stenting, endoscopic pig-tail drainage, percutaneous transhepatic drainage or dilatation. CONCLUSIONS: Palliative surgery for jaundice caused by extrahepatic bile duct cancer is justified in cases with an unsuccessful attempt for endoscopic stenting or occlusion of endoscopically placed endoprothesis. Bilio-enteric bypass with a Roux-Y jejunal loop is superior than external drainage respecting desicterization, postoperative recovery, mortality, complication rate and quality of life.

Importance of cytokines, nitric oxide, and apoptosis in the pathological process of necrotizing pancreatitis in rats.

OBJECTIVES: Ischemia-reperfusion injury can be involved in the pathophysiology of acute necrotizing pancreatitis. The aim of our study was to determine the production of cytokines, tumor necrosis factor (TNF) and interleukin-6 (IL-6), the activation of the inducible nitric oxide synthase (iNOS), and the development of apoptosis during this pathologic process. METHODS: Acute pancreatitis was produced in male Wistar rats by injection of 200 microL of 6% taurocholic acid into the main pancreatic duct in combination with the temporary (15 minutes) occlusion of the inferior splenic artery. Six and 24 hours later, the histologic damage was evaluated, and serum amylase, TNF, IL-6 levels, and iNOS and apoptotic activity from pancreatic and pulmonary tissues were determined. RESULTS: Twenty-four hours after the induction of pancreatitis, the mortality rate was 63%. During this period, the serum TNF and IL-6 levels were permanently high (50 +/- 12 and 58 +/- 10 U/mL and 7083 +/- 1610 and 6790 +/- 850 U/mL after 6 and 24 hours, respectively). The iNOS activity showed an increasing tendency in the pancreas, and a decrease following an initial increase in the lung (from 4.2 +/- 0.6 to 5 +/- 0.4 and from 6.8 +/- 0.6 to 3.8 +/- 0.5 pmol/min/mg protein after 6 and 24 hours, respectively). Histologic examination confirmed severe necrotizing pancreatitis. In the pancreas, the apoptotic activity increased significantly (from 4 +/- 4 to 27 +/- 5/mm at 6 and 24 hours), while in the lungs, following an initial increase it declined during the course of necrotizing pancreatitis (from 49 +/- 4 to 11 +/- 6/mm at 6 and 24 hours). CONCLUSION: Our results indicate that intraductal taurocholic acid and ischemia-reperfusion provokes severe acute necrotizing pancreatitis with a high mortality rate and leads to systemic inflammatory reaction, which appears to be the consequence of the activation of the cytokine cascade and iNOS. The degree of NO overproduction by iNOS corresponds with the apoptotic process in the pancreas and the lung.

Organ-preserving resection of the pancreatic head in patients with chronic pancreatitis.

INTRODUCTION: In chronic pancreatitis (CP), enlargement of the head of the pancreas develops in consequence of inflammatory alterations. A new safe procedure has been developed for duodenum-preserving pancreatic head resection, and this prospective report is concerned with the results attained with this operation. PATIENTS AND METHODS: In 94 patients a new surgical management was performed after the development of an inflammatory tumour of the pancreatic head. The preoperative morbidity comprised frequent abdominal pain, a weight loss in all patients, jaundice in 8 patients, and latent and insulin-dependent diabetes mellitus in 8 and 8 patients, respectively. The diagnosis was confirmed by ERCP, sonography and CT. Pancreatic functions were checked by means of the amylium tolerance test (ATT), the glucose tolerance test and stool elastase. The surgical procedure consisted in a local resection of the inflammatory tumour in the region of the pancreatic head, without division and cutting of the pancreas over the portal vein. Reconstruction, with drainage of the secretion from the remaining pancreas into the intestinal tract, took place through a jejunal Roux-en-Y loop. In 8 icteric cases and in 12 patients with stenosis of the common bile duct, prepapillary bile duct anastomosis was also performed with the jejunal loop. RESULTS: Only one reoperation was performed, in consequence of anastomosis bleeding, but no mortality was noted in the postoperative and follow-up period. The duration of hospitalization ranged between 7 and 12 days, with a median of 8.5 days. In the median follow-up period of 24 months (range 6 to 42), all the patients became complaint-free, and the weight increased by a mean of 10 kg (range 4-25). The ATT and the stool elastase level demonstrated an exocrine function improvement, no significant change was noted in the preoperative endocrine function. CONCLUSIONS: The results clearly reveal that this organ-preserving pancreatic head resection is a safe and effective procedure for definitive control of the complications following the inflammatory alterations of CP.

[Light- and temperature-induced degradation of fumagillin].

The antibiotic fumagillin with amebicidal and fungicidal effects isolated from Aspergillus fumigatus is the only presently known agent for the treatment of life threatening serious microsporidiosis occurring in patients with AIDS. Fumagillin and its degradation products were measured by HPLC at given time intervals after storage under defined conditions (temperature, relative humidity). Significant degradation took place even in samples stored in freezer; therefore fumagillin drug substance should be stored below -60 degrees C. Light also induced a degradation process in fumagillin, thus it is proposed to be stored and transported in brown glass.

[Pancreas resection for lung cancer metastasis].

This case report describes the successful resection of a solitary pancreatic metastasis that developed 21 months following lobectomy of an early pulmonary adenocarcinoma (pT1N0M0). The metastasis caused no complaints. The resected pancreas contained a glucagonoma in addition to the metastasis. In the literature we have found no similar case of simultaneous operable metastatic and a secondary pancreatic tumor.
