Pancreaticoduodenectomy for advanced duodenal and ampullary adenomatosis in familial adenomatous polyposis

Background

Patients with familial adenomatous polyposis (FAP) develop duodenal and ampullary polyps that may progress to malignancy via the adenoma–carcinoma sequence.

Objective

The aim of this study was to review a large series of FAP patients undergoing pancreaticoduodenectomy for advanced duodenal and ampullary polyposis.

Methods

A retrospective case notes review of all FAP patients undergoing pancreaticoduodenectomy for advanced duodenal and ampullary adenomatosis was performed.

Results

Between October 1993 and January 2010, 38 FAP patients underwent pancreaticoduodenectomy for advanced duodenal and ampullary polyps. Complications occurred in 29 patients and perioperative mortality in two. Postoperative histology revealed five patients to have preoperatively undetected cancer (R = 0.518, P < 0.001).

Conclusions

Pancreaticoduodenectomy in FAP is associated with significant morbidity, but low mortality. All patients under consideration for operative intervention require careful preoperative counselling and optimization.     

A portrait of district nursing: its contribution to primary health care

This paper explores the role and contribution of district nursing within primary health care. Examples of how this service is organised within different health care systems are used to discuss the context-dependent nature and challenges of the work. By drawing on UK policy change, health priorities and recent research into district nursing, the paper concludes that, in attempting to deal with the challenges of health care in the 21st century, the significance and potential of district nursing services are frequently overlooked. It is recommended that a research strategy for district nursing should build on the profession's comprehensive understanding of the needs of families and communities and should aim to provide evidence for practice that will further improve patient and client outcomes.     

Self-Efficacy,Depression, and Self-Care Activities in Adult Jordanians with Type 2 Diabetes: The Role of Illness Perception

Diabetes mellitus is reaching epidemic levels worldwide. In a developing country like Jordan, type 2 diabetes mellitus (T2DM) has reached a prevalence rate of 17.1%. This cross-sectional study examined the relationship between self-care activities and: illness perception, depression, social support, religiosity and spiritual coping, and self-efficacy among patients with T2DM. A random sample of 220 patients with T2DM, who attended Jordan University Hospital in Jordan were enrolled. The data were collected through a structured interview and the medical files. The instruments consisted of a sociodemographic and clinical standardised questionnaires: Brief Illness Perception Questionnaire, Patients’ Health Questionnaire-9; ENRICH Social Support Instrument; Religious and Spiritual Coping Subscale; Diabetes Management Self-Efficacy Scale; and Summary of Diabetes Self-Care Activities. Bivariate analysis investigated the relationship between variables. Structure Equation Modelling (SEM) was performed to test the proposed conceptual model. The study found that approximately 70% of the respondents suffered some form of depressive symptoms. The SEM showed a direct relationship between self-efficacy and self-care activities (β = 0.40; p < 0.001). Depression was indirectly related to self-care activities through self-efficacy (β = –0.20; p = 0.003); nevertheless, it was directly related to perception of: treatment control, consequences, and emotional representations. Overall, the sequence between illness perception and self-efficacy was mediated by depression. Strategies to promote self-efficacy and illness perception are vital in customising a diabetes health plan to meet Arabic cultural expectations.     

Thinking of the future and walking back to normal: an exploratory study of patients' experiences during recovery from lower limb fracture

Thinking of the future and walking back to normal: an exploratory study of patients' experiences during recovery from lower limb fracture ¶ Admission to hospital following a traumatic lower limb fracture is undoubtedly a stressful life event; however, few studies have detailed this from the patient's perspective. By exploring patients' experiences of hospitalization with lower limb trauma, this study aimed to explicate some of the factors impinging on the recovery trajectory. Patients' perceptions of the events influencing their strategies for coping with stress, hospitalization and temporary incapacity were investigated using a qualitative methodology. A convenience sample of nine patients was recruited from an orthopaedic ward in a district general hospital in Wales. The respondents used health diaries to document their recovery for up to 6 weeks after emergency surgery. These diaries were validated and supplemented by semi-structured interviews. Following their traumatic injuries, our respondents were subjected to a variety of stressors and uncertainties. They coped with this period of uncertainty by positive attempts to gain control over their situations, guided by an over-riding desire to 'return to normal' and assisted by the caring attributes of their nurses. From the experiences and events documented, this study was able to identify several stressors which could have been mitigated by optimization of the technical aspects of care, including the management of pain.     

Sequestration and microvascular congestion are associated with coma in human cerebral malaria

The pathogenesis of coma in severe Plasmodium falciparum malaria remains poorly understood. Obstruction of the brain microvasculature because of sequestration of parasitized red blood cells (pRBCs) represents one mechanism that could contribute to coma in cerebral malaria. Quantitative postmortem microscopy of brain sections from Vietnamese adults dying of malaria confirmed that sequestration in the cerebral microvasculature was significantly higher in patients with cerebral malaria (CM; n = 21) than in patients with non-CM (n = 23). Sequestration of pRBCs and CM was also significantly associated with increased microvascular congestion by infected and uninfected erythrocytes. Clinicopathological correlation showed that sequestration and congestion were significantly associated with deeper levels of premortem coma and shorter time to death. Microvascular congestion and sequestration were highly correlated as microscopic findings but were independent predictors of a clinical diagnosis of CM. Increased microvascular congestion accompanies coma in CM, associated with parasite sequestration in the cerebral microvasculature.     

Diagnosis, Clinical Presentation, and In-Hospital Mortality of Severe Malaria in HIV-Coinfected Children and Adults in Mozambique

Background.?Severe falciparum malaria with human immunodeficiency virus (HIV) coinfection is common in settings with a high prevalence of both diseases, but there is little information on whether HIV affects the clinical presentation and outcome of severe malaria. Methods.?HIV status was assessed prospectively in hospitalized parasitemic adults and children with severe malaria in Beira, Mozambique, as part of a clinical trial comparing parenteral artesunate versus quinine (ISRCTN50258054). Clinical signs, comorbidity, complications, and disease outcome were compared according to HIV status. Results.?HIV-1 seroprevalence was 11% (74/655) in children under 15 years and 72% (49/68) in adults with severe malaria. Children with HIV coinfection presented with more severe acidosis, anemia, and respiratory distress, and higher peripheral blood parasitemia and plasma Plasmodium falciparum histidine-rich protein-2 (PfHRP2). During hospitalization, deterioration in coma score, convulsions, respiratory distress, and pneumonia were more common in HIV-coinfected children, and mortality was 26% (19/74) versus 9% (53/581) in uninfected children (P?相似文献   

Effects of induction and maintenance plus long-term bisphosphonates on bone disease in patients with multiple myeloma: the Medical Research Council Myeloma IX Trial

The Medical Research Council Myeloma IX Trial (ISRCTNG8454111) examined traditional and thalidomide-based induction and maintenance regimens and IV zoledronic acid (ZOL) and oral clodronate (CLO) in 1960 patients with newly diagnosed multiple myeloma. Overall survival (OS) and skeletal-related event (SRE) data have been reported for the overall trial population. The present analysis investigated optimal therapy regimens for different patient populations in Myeloma IX. Patients were assigned to intensive or nonintensive treatment pathways and randomized to induction cyclophosphamide, vincristine, doxorubicin, and dexamethasone (CVAD) versus cyclophosphamide, thalidomide, and dexamethasone (CTD; intensive) or melphalan and prednisolone versus attenuated oral CTD (CTDa; nonintensive). Patients were also randomized to ZOL or CLO. In the nonintensive pathway, CTDa produced better responses and lower SRE rates than melphalan and prednisolone. ZOL improved OS compared with CLO independently of sex, stage, or myeloma subtype, most profoundly in patients with baseline bone disease or other SREs. In patients treated for ≥ 2 years, ZOL improved OS compared with CLO from randomization (median not reached for either; P = .02) and also from first on-study disease progression (median, 34 months for ZOL vs 27 months for CLO; P = .03). Thalidomide-containing regimens had better efficacy than traditional regimens, and ZOL demonstrated greater benefits than CLO.
