ABSTRACT

AIM: The aim of this study was to determine the effects of hepatitis B surface antigen (HBsAg) positivity of the donors on graft survival and liver complications in HBsAg(+) renal transplant recipients. PATIENTS AND METHOD: A group of 55 patients who underwent renal transplantation (RTx) in our hospital between 2001 and 2012 were included in the study. Patients were divided into 2 groups. Group 1 (n = 50) consisted of HBsAg(+) renal transplant recipients (RTR) whose donors were HBsAg(-). In Group 2 (n = 5), RTR and donors were both HBsAg(+). Lymphocyte cross matches, number of mismatches, donor types, renal replacement treatment modalities, drugs of induction treatment, and preoperative hepatitis B virus DNA titers of the groups were similar. In Group 1, 42 patients were taking lamivudine, 3 patients were taking entecavir, and 5 patients were taking tenofovir. All of the patients in Group 2 were taking lamivudine. Patient and graft survival rates, graft functions, acute hepatitis rates, acute rejection rates, and other clinical outcomes of the groups were compared. RESULTS: Demographic data of the groups were similar. Acute rejection rates (P = 0.458), graft survival rates (P = 0.515), and patient survival rates (P = 0.803) were also similar. No significant difference was found between the groups in terms of acute hepatitis rate (P = 0.511), glomerular filtration rate (calculated by Modification of Diet in Renal Disease formula) in the last follow-up (P = 0.988), alanine aminotransferase levels (P = 0.069), or delayed graft function rate (P = 0.973). Rates of chronic allograft dysfunction and new onset diabetes mellitus after transplantation were similar. CONCLUSION: Our study revealed that, RTx from HBsAg(+) donors to HBsAg(+) recipients is safe with antiviral treatment.

ABSTRACT

Renal transplantation is the most effective treatment method for end-stage renal disease (ESRD). However, new treatment modalities are being investigated, such as immunotoleration, to avoid the acute and chronic side effects of immunosuppressant drugs. We report a case in which a man had undergone allogenic stem cell transplantation from his brother 16 years ago due to chronic myeloid leukemia, and who then developed ESRD due to arterial hypertension and underwent renal transplantation (Rtx) from the same brother. The patient was followed up without immunosuppression due to full chimerism.

ABSTRACT

Due to surgical technical difficulties, inferior vena cava (VCI) thrombosis is contraindicated for renal transplantation in pediatric patients. Of 287 pediatric renal transplantations, 3 patients (9, 12, and 19 kg, respectively) with end-stage renal failure, who had VCI thrombosis at the level of renal vein, underwent end-to-end anastomosis to the proximal aspect of VCI for venous drainage. The latest creatinine values of the patients, who were in the postoperative 56(th), 28(th), and 14(th) months, were 0.6, 0.4, and 0.3 mg/dL, respectively, with graft and patient survival rates of 100%. We think that end-to-end venous drainage into the proximal caval system is the most appropriate surgical approach in pediatric recipients, who have an open suprarenal VCI and a small intra-abdominal cavity, in the presence of an appropriate size-matched graft.

ABSTRACT

AIM: This study aimed to investigate protective effects of ellagic acid on lungs in an experimental obstructive jaundice model. METHODS: Four groups were established, each consisting of ten randomly selected rats: Group 1: sham, Group 2: ellagic acid, Group 3: obstructive jaundice, and Group 4: obstructive jaundice + ellagic acid. Ellagic acid was administered orally at a dose of 60 mg/kg/day to group 2 and 4. The animals were sacrificed eight days later. The total oxidative status and the total antioxidant capacity in their lung tissue were determined, and malondialdehyde levels in their blood were measured. Histopathological changes in the lungs were examined. RESULTS: In the obstructive jaundice group treated with ellagic acid, there was a decrease in malondialdehyde levels and a reduction in the total oxidative status and the oxidative stress index, whereas the total antioxidant capacity increased (p < 0.001). The histopathological examination showed that neutrophil leukocyte infiltration and edema formation decreased and destruction of lung parenchyma disappeared following the treatment with the ellagic acid (p < 0.05). CONCLUSION: This study shows that ellagic acid has a protective effect against oxidative damage in lung tissue in obstructive jaundice.

ABSTRACT

BACKGROUND: Pancreatic injuries arising from blunt trauma are rarely seen. Diagnosis and treatment are difficult because of retroperitoneal localization of the organ. We present four pancreatic cases with isolated pancreatic injury due to blunt abdominal trauma. METHODS: This retrospective study included four pancreatic patients who were operated on due to isolated injury caused by blunt abdominal trauma at our department between January 2004 and October 2010. RESULTS: The patients consisted of three males and one female. One of them was in stage IV and the rest were in stage III. All underwent pancreaticojejunostomy, distal pancreatectomy, distal pancreatectomy + splenectomy and drainage, respectively. Fistula developed in two of them, and abscess developed in one, while the other one died. CONCLUSION: Diagnosis may be delayed since the clinical condition is initially stable. Tomography remains one of the most important diagnostic tools. Common risk factors for morbidity and mortality are the presence of ductal injury and delayed laparotomy (Tab. 1, Fig. 4, Ref. 22).

ABSTRACT

BACKGROUND: Damage control surgery is a life-saving procedure used in fatal injuries. Morbidity and mortality rate are high in these patients due to massive trauma. The aim of this study was to analyze the risk factors associated with mortality in abdominal traumas that underwent damage control surgery. PATIENTS AND METHODS: The retrospective study included 24 patients that underwent damage control surgery between January 2004 and September 2010. Age, gender, type of injury, period of time before admission, hemodynamic parameters, associated organ injury, injury severity score, surgical procedures performed, length of hospital stay, and complication and mortality rates were recorded. RESULTS: The study included 16 (66.7%) men and 8 (33.3%) women, with a mean age of 32.3 years. Median period of time before admission was 30.83 minutes. All the patients were present with hypothermia and acidosis at admission, while only 5 of them were hemodynamically stable. Mean 6.75 units of blood were transfused in all of them. Common etiological factors included gunshot (50%) and motor vehicle accident (25%). Hepatic injury (83.3%) was the most common organ injury. Mean injury severity score (ISS) was 28.88. Damage control surgery was performed in all the patients. Skin-only closure was applied in 17 (70.8%), while 7 (29.2%) patients received Bogota bag application. Definitive surgery was achieved through de-packing over 36-48 hours in average. Total mortality occurred in 11 (45.8%) patients. Period of time before admission, core temperature at admission, pH levels and amount of blood transfusion were statistically different in the mortality group. A total of 16 complications occurred in 10 patients. Among these, intraabdominal abscess (46.2%) was the most common. CONCLUSION: Hypothermia (< 35°C), acidosis (pH < 7.2), instability related to systolic blood pressure, massive blood transfusion, and delayed admission are predictive factors for mortality.

ABSTRACT

BACKGROUND: The aim of this study was to investigate the effects of prostaglandin E-1 (PGE-1) on preservation injury in livers perfused with the University of Wisconsin (UW) or histidine-tryptophan-ketoglutarate (HTK) solutions. MATERIALS AND METHODS: Five groups each including six rats included. Ringer's lactate RL (group 1), HTK (group 2), HTK + PGE-1 (group 3), UW (group 4), or UW PGE-1 (group 5). Liver tissue and preservation fluid samples were obtained from the perfused lives for pathological and biochemical examinations respectively at 0, 6 and 12 hours. RESULTS: Upon biochemical examination, aspartate aminotrasnferase and alanine aminotransferase values were highest among the group with RL solution and lowest with PGE-1. Liver structure was found to be damaged immediately after RL solution, whereas it was preserved in the other four groups. Fewer cellular changes were reported at the end of 12 hours in the groups administered PGE-1 compared with the other groups. CONCLUSIONS: PGE-1 when applied before preservation protected liver functions, decreased pathologic injury, and delayed changes that occur under cold ischemic conditions.

ABSTRACT

INTRODUCTION: Sigmoid volvulus is an important acute intestinal obstruction, leading to high mortality and requiring urgent operation. The purpose of this study is to analyze risk factors for mortality in patients that were operated on due to sigmoid volvulus at our Department. MATERIALS AND METHODS: The retrospective study included 158 patients, who were operated on due to sigmoid volvulus between January 1994-December 2010, in terms of age, gender, complaints at admission, physical signs, period of symptoms before admission, associated diseases, laboratory and radiological parameters, hospital stay, morbidity, and mortality. RESULTS: The study consisted of 135 men (85.4%) and 23 women (14.6%), with a mean age of 62.54 years. Cardiovascular disease and respiratory disease were present in 34 (21.5%) and 42 (26.6%) patients, respectively. Urgent operation was undertaken in 125, while 33 received elective surgery. Abdominal distension and pain was evident in all the patients. Generalized tenderness was detected in 58.2%, while 70.9% had hyperactive bowel sound with tympanism. Plain radiograph revealed an impression of "omega ans" in all patients, while free air was detected in 11.4% of them. Risk factors for mortality included age (p = 0.008), delayed admission (p = 0.001), cardiovascular and respiratory diseases (p = 0.001), fluid-electrolyte imbalance (p =0.001), presence of necrosis (p = 0.001), and major contamination (p = 0.001). Wound infection and intraabdominal abscess were more common in patients that developed mortality (p = 0.001 and p = 0.002). CONCLUSIONS: Complications like wound infection and intraabdominal abscess are more frequent in the patients with the risk of mortality. Delayed admission results in higher risk of mortality. Mortality rates can be reduced by early admission, preoperative intensive resuscitation, suitable antibiotics, and emergent and viable surgery.

ABSTRACT

PURPOSE: Scald burns are the leading cause of burns in children, especially in those younger than 5 years of age, however, they are easily preventable. Our aim in this study was to emphasise the importance and impact of scald burns caused by hot milk. METHODS: A total of 334 patients below seven years of age were included in this study. Of these, 252 were admitted with acquired hot water scald burns (Group 1) and 82 with hot milk scald burns (Group 2) between August 2009 and September 2010. Demographic data of the patients were retrospectively investigated. RESULTS: The depth of the burns was determined to be higher in Group 2 (p < 0.001). The total burnt body surface area in Group 1 and Group 2 were 17.1 ± 12.3 and 16.3 ± 10.9 (p = 0.99), respectively. Skin grafting was performed in 23 patients in Group 1 and 16 patients in Group 2 (p = 0.01) and complications developed in three patients in Group 1 and in five patients in Group 2 (p = 0.01). The mean length of hospital stay was 9.1 ± 7.4 days in Group 1 and 14.9 ± 9.8 days in Group 2 (p < 0.001) and the mortality rates were similar between the two groups. CONCLUSIONS: More emphasis should be placed on the effects of hot milk scalding due to its ominous clinical course and the high healthcare costs associated with this type of scalding. We believe that taking simple precautions would help reduce the physical, psychological effects and financial consequences of hot milk scalds.

ABSTRACT

To show drug interactions between tacrolimus and ertapenem, we retrospectively evaluated 13 renal transplant recipients who had been treated with ertapenem for urinary tract infections during prescription of a constant dose. The mean dose of tacrolimus to achieve desired therapeutic concentrations decreased significantly after beginning ertapenem. The decrease from 0.079 mg/kg to 0.043 mg/kg occurred 2 days after initiation of ertapenem (P < .005). These results suggest that ertapenem, which is not metabolized through the cytochrome (CYP) P450 3A metabolic pathway, interacts with tacrolimus by an unknown mechanism. This report recommends tacrolimus concentration monitoring and dose reductions when the two drugs are administered in combination.

ABSTRACT

INTRODUCTION: We aimed to investigate the possible protective effects of ellagic acid (EA) on the liver and remote organs against the hepatic ischemia-reperfusion injury. METHODS: Forty Wistar-Albino rats were divided into four groups each containing 10 rats. Group I with laparotomy only, Group II with laparatomy and ellagic acid application, Group III with hepatic ischemia-reperfusion and Group IV with hepatic ischemia-reperfusion and ellagic acid application. Hepatic ischemia was induced by pringle's manoeuvre for 30 minutes followed by 30 minutes reperfusion period. After induction of ischemia, EA was applied via oral gavage at a dose of 85 mg/kg. Blood samples were taken from the animals for biochemical analysis at 60th minute of the experiment in all groups. Simultaneously, liver, lung and kidney tissues were sampled for biochemical analyses and histopathological examinations. RESULTS: The administration of EA reduced serum malonyldialdehid levels (p<0.05) and liver's oxidative stress index compared with the non-use EA groups (p0.05). The use of EA did not exert significant protective effects against the effects of liver ischemia-reperfusion injury on the kidney and lung. CONCLUSION: In our experiments ellagic acid reduced the liver oxidative stress induced by ischemia-reperfusion injury. However, no significant histological improvement was found with EA. There were no significant protective effects on the remote organ injuries induced by ischemia-reperfusion (Tab. 3, Fig. 7, Ref. 37).

ABSTRACT

PURPOSE: The aim of this study was to evaluate the outcome of non-operative management (NOM) in patients with splenic injuries and to determine the predictive factors of NOM failure. METHODS: Two hundred and six patients with splenic injury were admitted between January 2005 and April 2011. Of the 206 patients with splenic injury, 47 patients met the inclusion criteria of NOM. The mechanism of injury, grade of splenic injury, other intra- and extra-abdominal injuries, systolic blood pressure on admission, hemoglobin levels, number of transfusions, Injury Severity Score (ISS), Glasgow Coma Scale score, and hospitalization period were recorded. The patients were divided into two groups: those with NOM and those in whom the failure of NOM led to laparotomy. The patients were monitored for vital signs, abdominal findings, and laboratory data. NOM was abandoned in cases of hemodynamic instability, ongoing bleeding, or development of peritonitis. Independent predictive factors of NOM failure were identified. The patients managed non-operatively were compared with the patients for whom NOM failed. RESULTS: NOM was successful in 40 of 47 patients. There were differences between the two groups for ISS, hemoglobin levels, need for blood transfusion, and the number of associated extra-abdominal injuries. The grade of splenic injury was determined to be an important and significant independent predictive factor for the success of NOM of splenic injuries. CONCLUSIONS: The grade of splenic injury is an important and significant independent predictor factor for the success of NOM. NOM is not recommended in patients with high-grade splenic injury.

ABSTRACT

PURPOSE: Rectal injuries, which are rarely encountered because of the anatomic characteristics, occur due to penetrating traumas. In the current study, we aimed to present experiences gleaned from our clinic concerning rarely encountered unusual rectal injuries, including those cases presented for the first time. METHODS: Eleven patients who had been treated for unusual rectal injuries in the General Surgery Clinic of Dicle University between 2004 and 2011 were retrospectively reviewed. RESULTS: The reasons for rectal injuries included foreign bodies in four cases, sexual intercourse in three cases, iatrogenic injuries in two cases, electric shock in one case, and animal horns in one case. All cases had extraperitoneal rectal injuries and all injuries were grade 2 injuries, except for the electrical burn. Primary repair was adequate for the treatment of six patients. Four patients underwent primary repair and ostomy, whereas one of the patients underwent debridement and an ostomy. The patients recovered without complications, except for one patient with sphincter insufficiency. CONCLUSION: The results of the current study suggested that primary repair is adequate in the patients with low-energy injuries and early presentation, whereas an ostomy is required for those with late presentation and for those with high-energy and destructive injuries.

ABSTRACT

Wilson's disease is an inherited disorder of copper metabolism characterized by reduced biliary copper excretion, which results in copper accumulation in the tissues with liver injury and failure. Orthotopic liver transplantation (OLT) can be lifesaving for patients with Wilson's disease who present with fulminant liver failure and for patients' unresponsive to medical therapy. The aim of this study was to review our experience with OLT for patients with Wilson's disease. Between September 2001 and April 2007, 25 OLTs were performed in 24 patients (7 females and 17 males) with Wilson's disease of mean age 15.6 +/- 9.9 years (range, 5-51 years). Six patients underwent transplantation owing to coexistent fulminant hepatic failure and 18 with chronic advanced liver disease with (n = 8) or without (n = 10) associated neurologic manifestations. We performed 3 full-size, deceased-donor OLTs and 22 living-related donor OLTs. Eight patients had a family history of Wilson's disease. We detected a Kayser-Fleischer ring in 18 patients. All patients had a low serum ceruloplasmin level (mean, 27.8 mg/dL) and a high urinary copper excretion level (mean, 4119 mug/d) before OLT. Following successful OLT, there was a significant reduction in urinary copper excretion (median, 37.1 mug/d) in all patients. Mean follow-up was 21.7 +/- 19.8 months (range, 2-60 months). Retransplantation was required in 1 patient at 12 days after the first OLT owing to primary graft nonfunction. Five of the 24 patients died within 4 months of the surgery. The remaining 19 survivors (79%) have remained well, with normal liver function and no disease recurrence. In conclusion, OLT was a curative procedure for Wilson's disease among patients presenting with fulminant hepatic failure and others with end-stage hepatic insufficiency. After OLT, the serum ceruloplasmin level increased to the normal range, urinary copper excretion decreased, and neurologic manifestations improved.
