Recurrence Pattern and Prognosis of Pancreatic Cancer After Pancreatic Fistula

Background

The negative impact of anastomotic leakage on cancer-specific survival and recurrence patterns has been recognized in colorectal cancer. In pancreatic cancer, pancreatic fistula (PF) is a serious morbidity, but its negative effect on long-term outcome remains to be elucidated. The aim of this study was to determine the impact of PF on pancreatic cancer recurrence.

Methods

The medical records of 184 patients with curative pancreatectomy for pancreatic cancer were reviewed. PF was scored on the basis of the International Study Group of Pancreatic Fistula classification. Overall and disease-free survivals and recurrence patterns were analyzed. Grade A PF was excluded because the negative effects can be negligible.

Results

PF occurred in 51 of the 184 patients (27.7%). The mortality related to PF was 0.5% (1 of 184). PF was an independent risk factor for peritoneal recurrence (hazard ratio 3.974; 95% confidence interval 1.345–11.737; P = 0.013). According to the analysis of disease-free survival in patients with peritoneal recurrence, time to recurrence was shorter and the survival rate was worse in patients with PF than in those without PF (5.6 vs. 8.2 months; 6-month survival, 40 vs. 71%; 1-year survival, 7 vs. 19%; P = 0.053). PF was an independent prognostic factor after multivariate analysis (hazard ratio 3.257; 95% confidence interval 1.201–8.828; P = 0.020).

Conclusions

PF was statistically significantly related to peritoneal recurrence, and patients with PF developed peritoneal recurrence earlier than those without PF. With regard to the development of peritoneal recurrence, PF may be considered to be a negative prognostic factor.

     

A Preoperative Predictive Scoring System for Postoperative Pancreatic Fistula after Pancreaticoduodenectomy

Background  

Postoperative pancreatic fistula (POPF) remains a leading cause of morbidity after pancreaticoduodenectomy (PD). In the present study we sought to establish a preoperative scoring system with which to predict this complication.     

Perioperative cardiopulmonary complications after cervical spine surgery in the prone position: the relationship between age and preoperative testing

Background  

Cardiac arrest during spine surgery in the prone position is difficult to manage as poor access makes cardiopulmonary resuscitation and defibrillation difficult. Advanced age is the maximal risk factor for cardiac arrest. Therefore, we wanted to determine the relationship between age and cardiac risk factors/pre-operating tests for cervical spine surgery in the prone position.     

Familial lateral temporal lobe epilepsy confirmed with intracranial electroencephalography and successfully treated by surgery

Documentation of familial epilepsy is of paramount importance for identification of epilepsy-associated genes, elucidation of pathomechanisms of epilepsy, and development of treatment of epilepsy. We report a Japanese family with 5 members with lateral temporal lobe epilepsy beginning around the second decade of life. All seizures were intractable to medical treatment, and four patients underwent surgical treatment following long-term monitoring by intracranial electroencephalography with subdural electrodes, which revealed neocortical origins for the seizure. These four patients were successfully treated with surgery. The clinical features of this familial temporal lobe epilepsy seem to be different from those of previously reported types of familial temporal lobe epilepsy.     

Optimum initial dose of silodosin for treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia

We investigated the optimum initial dose and timing of administration of α1A-adrenoceptor antagonist silodosin for treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH/LUTS). Ninety-eight patients were given a 4 mg dose after breakfast (group A), 4 mg after supper (group B), or 4 mg after breakfast and after supper (group C). At baseline, 4, 8 and 12 weeks after treatment, we assessed International Prostate Symptom Score (IPSS) and quality of life (QOL) index. Twenty-five percent or less improvement of total IPSS and no improvement of QOL index compared with baseline were defined as treatment failure at each evaluation point. Otherwise treatment was considered effective. In group A and group B, patients with treatment failure at 4 or 8 weeks after treatment, the dose of silodosin was increased to 8 mg daily. At the end of the study, 83 patients were evaluable. At 12 weeks after treatment, 20 of the 31 patients in group A and 22 of the 29 patients in group B remained on the 4 mg dose ; silodosin was effective in 65 and 76% of the patients, respectively. When patients with dose escalation were included, silodosin was effective in 81 and 90% of the patients, respectively. Silodosin was effective in 18 of the 23(78%) patients in group C, although improvement of total IPSS and voiding symptom score of IPSS at 12 weeks after treatment was better in group C than in group A or group B, the difference was not significant. In patients with IPSS less than 20, the degree of improvement of IPSS was similar among the 3 groups. In contrast, in patients with IPSS of 20 or greater the degree of improvement was better in group C than in group B or group C, but the difference was not significant. Storage symptom score of IPSS was significantly improved in all 3 groups without any significant difference among the 3 groups. Three patients (52, 59 and 76 years old) experienced abnormal ejaculation. In conclusion, 4 mg of silodosin daily showed effectiveness against BPH/LUTS, but 8 mg of silodosin daily might be better for patients with severe LUTS.     

Staged hybrid repair using telescoped stent graft fixation for aortic arch and descending aortic aneurysms

Staged repair of extensive thoracic aortic aneurysms is complicated, with a high incidence of interval rupture between stages. We describe the systematic staged hybrid procedure of a previous endovascular repair of a descending aortic aneurysm and open surgical repair of an aortic arch aneurysm. In the second-stage arch repair, the stent graft was easily retracted and fixed, without dissection, around the aortic arch aneurysm distal side. Extensive thoracic aortic aneurysms were managed without interim rupture or neurologic deficits. This approach avoided the potential for interim rupture because recovery from the first-stage endovascular repair was shorter than that from open repair.     

Injury and pre-hospital trauma care in Hanoi, Vietnam

BACKGROUND: In Vietnam, injury is the leading cause of death in children under 18, and road traffic accidents are the fifth leading cause of death. Information systems for pre-hospital trauma care are insufficient. OBJECTIVES: The objective of this study was to assess injury morbidity and mortality, and the existing level of pre-hospital trauma care in Hanoi city. RESEARCH DESIGN AND SUBJECTS: A cross-sectional study was conducted in seven districts in Hanoi in 2006. We studied 2800 households (11,334 members), 9 hospitals and an emergency service centre. RESULTS: The injury morbidity rate was 1134/100,000 (year(-1)), and the injury mortality rate was 23.7/100,000 (year(-1)). There was no significant difference in age or sex between injury severity levels (p>0.05). Road traffic accidents were the leading cause of injury. Causes of injury mortality differed among different age groups. Only 4% of injured cases were transported to hospital by ambulance. Fifty-two percent of victims did not receive first aid at the site. Pre-hospital trauma care was separately provided by the emergency service centre and hospitals. There was no communication network between the emergency service centre and hospitals, ambulances and hospitals, or between different hospitals. CONCLUSIONS: The results reveal that injury is a major health problem in Hanoi and that the pre-hospital care system lacks both coordination and many vital components. Study results may assist decision-makers in identifying interventions to improve health and safety for the population of Hanoi.     

Incidence and outcome of osteoporotic fractures in 2004 in Sado City,Niigata Prefecture,Japan

Osteoporotic fracture in elderly populations is increasing worldwide, but there are few data on the incidence and outcome of osteoporotic fractures, including upper extremity and vertebral fracture, during a certain period in a defined geographic area. The purpose of this study was to determine the incidence of osteoporotic fractures in a particular area: Sado City, Niigata Prefecture, Japan. From January to December 2004, osteoporotic fractures of the vertebra, hip, distal radius, and proximal humerus in Sado City were recorded. The incidence, age, gender, type of fracture (for hip fracture), right or left side (for distal radius, proximal humerus, and hip fracture), place of injury, cause of injury, outcome, hospitalization period, and patient status regarding taking of drugs for osteoporosis treatment were checked for each fracture. The incidence was calculated based on the whole population of Sado City. The incidence per 100,000 population was 232.8, 121.4, 108.6, and 37.1 for fractures of the vertebra, hip, distal radius, and proximal humerus, respectively. The total incidence of these four kinds of fracture was 499.9 per 100,000 persons per year. The average age at the time of injury was 81.4, 77.7, 75.7, and 60.2 years old for fractures of the hip, vertebra, proximal humerus, and distal radius, respectively. As the average age increased, the percentage of fractures that occurred indoors also increased; that is, a higher percentage of hip fractures occurred indoors, followed by fractures of the vertebra, proximal humerus, and distal radius. Most patients were not taking anti-osteoporosis drugs before fractures of the hip or vertebra. We determined the incidence of major osteoporotic fractures in 1 year in a defined geographic area. Our data showed that 81% of hip fracture patients also had a vertebral fracture and that the average age at the time of injury was higher for hip fractures than for vertebral fractures. Therefore, these results suggest that vertebral fracture leads to hip fracture, indicating that early fracture prevention and continuous prevention strategies through positive treatment are of importance in osteoporotic elderly people.     

Surgical cryoablation and left ventriculoplasty for electrical storm after acute myocardial infarction

A 65-year-old man was referred to our hospital to treat recent anterior myocardial infarction. Coronary artery angiography showed acute occlusion of left anterior descending coronary artery (LAD) and chronic occlusion of right coronary artery. After emergent percutaneous coronary intervention for LAD, drug-refractory electrical storm necessitating frequent electrical defibrillating cardioversion occurred. This patient successfully underwent surgical cryoablation, left ventriculoplasty and coronary revascularization. At 2 years and 10th month after the operation, he is well without limitation of daily activities and any evidence of myocardial ischemia and ventricular tachycardia.     

Behçet’s disease complicated by IgA nephropathy with nephrotic syndrome

A 65-year-old woman with a 48-year history of Behçet’s disease associated with nephrotic syndrome is described. Immunofluorescence study revealed IgA nephropathy. Following treatment with an angiotensin II type-I receptor-blocker, an anti-platelet drug, and an HMG-CoA reductase inhibitor, accompanied by dietary restrictions of protein and sodium, proteinuria was markedly decreased. This report describes our experience with a rare entity of Behçet’s disease complicated by nephrotic syndrome due to IgA nephropathy. Routine urine examination and renal biopsy are needed for the detection and diagnosis of renal problems with Behçet’s disease.
