Steroid-Induced Pancreatitis: Establishing an Accurate Association Poses a Challenge

The association between steroids and pancreatitis has been reported in the literature. However, due to its rarity, it can be challenging to make an early diagnosis. Hence, when diagnosing patients presenting with signs and symptoms of pancreatitis, there should be a high suspicion for medication-induced variants, after ruling out other common causes. In our report, we present the case of an individual with recurrent pancreatitis caused by the use of prednisone for musculoskeletal pain, the probable cause being steroids due to a high Naranjo score. The patient experienced clinical improvement with the resolution of pancreatitis after the steroids were discontinued.

First report of blood parasites in fishes from Kashmir and their effect on the haematological profile

Cyprinus carpio communis Linnaeus, Carassius carassius Linnaeus, Schizothorax curvifrons Heckel and Triplophysa marmorata species of fishes were captured from Anchar Lake and river Jhelum of Kashmir Himalaya for hematological and parasitological analysis. During the investigation haemoflagellates from the genus Babesiosoma and Trypanosoma were recorded in the blood smears. Trypanosomes were present in all the species except C. carpio, whereas Babesiosoma were only found in T. marmorata. Haematological analysis revealed a significant (p<0.01) reduction in red blood cell count in the fishes infected with Babesiosoma and Trypanosoma. A significant decrease (p<0.05) was recorded in haemoglobin value and packed cell volume in the infected fishes in comparison to the non-infected fishes.

External validation of prognostic model of one-year mortality in patients requiring prolonged mechanical ventilation

BACKGROUND

External validation of prognostic model for one-year mortality in patients ventilated for 21 days or more. A measure that identifies patients who are at high risk of mortality after prolonged ventilation will help physicians communicate prognoses to patients or surrogate decision makers. Our objective was to validate a prognostic model developed by Carson et al in a different setting.

METHODS

An observational study was conducted from September 2002 to September 2007 in 30 beds Medical/Surgical Intensive Care Unit (ICU) at Mercy Fitzgerald Hospital (MFH) and 20 beds Medical/Surgical ICU at Mercy Philadelphia Hospital (MPH). One hundred and fifty medical and surgical patients requiring mechanical ventilation after acute illness for at least 21 days after initial intubation were enrolled.

RESULTS

One year mortality was 45.4%. Area under the receiver operating characteristic curve for three month mortality was 0.90 and for one year mortality was 0.92. For identifying patients who had ≥90% risk of death at 3 month had sensitivity of 40% and specificity of 95% and risk of death at 1 year had sensitivity of 70% and specificity of 99%. Four predictive variables, requirement of vasopressors, hemodalysis, platelet count ≤ 150 x 10 9/L and age ≥50 yrs can be used as a simple prognostic score that clearly identifies low-risk patients and high-risk patients.

CONCLUSIONS

Simple clinical variables measured on day 21 of mechanical ventilation can identify patients at highest and lowest risk of death from prolonged mechanical ventilation.

Laparoscopic fenestration of non-parasitic liver cysts and health-related quality of life assessment

Although laparoscopic fenestration has become an established treatment in symptomatic liver cyst patients in the recent years, the success of surgical treatment cannot only be evaluated by post-operative morbidity and mortality. Therefore, the aim of this study was to analyze the safety of laparoscopic fenestration of non-parasitic liver cysts and to assess the impact of this therapy on patients' quality of life. A total of 43 patients who underwent laparoscopic fenestration of non-parasitic liver cysts at our center were included in this study. Post-operative course was assessed and patients' quality of life was evaluated before surgery and at present time using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ C-30). The results were that, post-operative morbidity and mortality rates were 0%. After a median follow-up of 49 months (19-97 months) the recurrence rate was 11.1% for simple liver cysts (SLC) and 42.9% for polycystic liver disease (PCLD). Thirty-one out of 43 patients (72.1%) completed the EORTC C-30 questionnaire. There was highly significant post-operative improvement in global health status (p < 0.001) as well as in physical (p = 0.002), role (p = 0.004), emotional (p = 0.003) and social (p = 0.001) functioning. Furthermore, a significant reduction of symptoms could be shown for pain (p < 0.001), nausea and vomiting (p = 0.001), appetite loss (p = 0.006), insomnia (p = 0.04) and fatigue (p = 0.025). To conclude, laparoscopic fenestration of symptomatic non-parasitic liver cysts is a safe procedure with good long-term results and the patients' benefit of this intervention is excellent as shown by highly significant improvement in patients' quality of life.

The Preceptor Model of Clinical Instruction: The Lived Experiences of Students, Preceptors, and Faculty-of-Record

The preceptor model of clinical instruction will become increasingly popular due to the cost of undergraduate education, the scholarly demands of research and teaching, and an interest in developing new partnerships among students, clinicians, and teachers. It is quite timely, therefore, that nurse researchers reveal the nature and utility of this instructional model prior to its widespread use. To that end, hermeneutic interviews (N = 31) were conducted with senior-level undergraduate nursing students (n = 10), staff nurse preceptors (n = 11), and master's and PhD-prepared faculty-of-record (n = 10). Employing interpretive phenomenology, the authors identified common meanings, relational themes, and a constitutive pattern designated learning nursing thinking. An examination of this pattern and its associated themes may help identify those teaching practices that should be extended and those that should be altered.
