Spirituality and the quality of life of cancer patients: An antidepressant effect.

OBJECTIVES: Cancer is the second leading cause of mortality in the world, and represents an economic, social and psychological burden. Scientific studies have focused on psychosocial coping mechanisms of patients and on factors improving their quality of life. Thus, the aim of the present study is to analyze the influence that spirituality would have on the quality of life of Lebanese cancer patients and to identify whether the influence on quality of life is mediated through a decreased depression. METHODS: This is a cross-sectional study targeting cancer patients in the hemato-oncology department of the Hôtel-Dieu de France Hospital (Beirut, Lebanon). It is based on a questionnaire composed of three parts: EQ-5D-5L, PHQ-9, and FACIT-Sp-12. Likewise, a control group suffering from chronic diseases and treated in the hospital was questioned. Univariate and multivariate analysis were conducted to assess the relationship between the different questionnaires for controls and for cancer patients. RESULTS: Thirty-nine cancer patients and eight control patients were questioned. In the univariate analysis, there was no relationship between depression and spirituality nor for spirituality and quality of life. After controlling for depression, an inverse correlation between quality of life and spirituality was shown. CONCLUSIONS: Our study is a pilot study which for the first time investigates the implication of depression in a "spirituality-quality of life" association. There is no clear association of spirituality with quality of life. In fact, the physical and psychological burden of chronically ill patients could exceed and render insignificant a possible impact of spirituality on quality of life.

Intradialytic hypotension: beyond hemodynamics.

Intradialytic hypotension is a major complication during hemodialysis session, associated with increased risk of cardiovascular events and mortality. Its pathophysiology is believed to be multifactorial and remains not well elucidated. The aim of this study is to put forward new mechanisms behind the development of intradialytic hypotension. The study included sixty-five subjects on chronic hemodialysis, divided into two groups: intradialytic hypotensive (n=12) and normotensive (n=53), according to the variation of systolic blood pressure between post-dialysis and pre-dialysis measurements. Renin and angiotensin converting enzyme I plasma concentrations increased in both groups but more likely in normotensive group. Aldosterone plasma concentration is increased in the normotensive group while it decreased in the intradialytic hypotension group. Plasma endothelin concentrations showed higher values in intradialytic hypotension group. Post-dialysis asymmetric dimethylarginine and angiotensin converting enzyme 2 plasma concentrations were significantly higher in intradialytic hypotension group as compared to normotensive one. Collectrin plasma concentrations were significantly lower in intradialytic hypotension group. Finally, post-dialysis vascular endothelial growth factor C plasma concentration significantly increased in intradialytic hypotension group. In conclusion, endothelial dysfunction characterized by a lower level of vasoactive molecule seems to play a critical role in intradialytic hypotension development.

Comparing laparoscopic and percutaneous renal biopsy for diagnosing native kidney disease: A matched pair analysis.

BACKGROUND: Percutaneous renal biopsy is a well-established diagnostic procedure in patients with underlying medical renal disease. Aim of this study is to compare the adequacy of the biopsy material, the diagnostic yield, and the complication rates of the trans-peritoneal laparoscopic approach and the image-guided percutaneous approach to renal biopsy in the diagnosis of native kidney disease. METHODS: We performed a matched-pair analysis matching 1:3 40 patients who underwent trans-peritoneal laparoscopic renal biopsy to 120 patients who underwent percutaneous renal biopsy in the same years. Patients were retrospectively analyzed. Differences in adequacy of biopsy material (i.e. number of glomeruli, continuous), diagnostic yield (categorical) and postoperative complications across the two groups were assessed using Wilcoxon Rank sum or χ2 test. RESULTS: Laparoscopic biopsy was associated with a higher number of harbored glomeruli (median 50, IQR 20-77) compared to the percutaneous approach (median 10, IQR 7-15), P<0.001. Adequate biopsies containing at least ten glomeruli were obtained in a significantly higher percentage of patients in the laparoscopic group versus the percutaneous group (92.5% vs. 57.1%, P<0.001). The laparoscopic approach was also associated with a significantly higher diagnostic yield than the percutaneous approach (82.5% vs. 63.5%, P=0.027). Patients who underwent laparoscopic biopsy had no perioperative or postoperative complications, resulting in a significantly lower complication rate than percutaneous biopsy (0% vs. 4%, P<0.001), particularly in the need for transfusion for post-procedure bleeding (0% vs. 1.8%, P<0.001). CONCLUSIONS: In this retrospective matched-pair analysis comparing patients undergoing renal biopsy for medical kidney disease, trans-peritoneal laparoscopic renal biopsy was safer and more effective for the diagnosis of medical renal diseases compared to percutaneous renal biopsy. Prospective trials with a good follow-up are needed to define the best candidate for each approach. LEVEL OF EVIDENCE: 4.

Trimethoprim-Sulfamethoxazole-induced Hepatotoxicity in a Renal Transplant Patient.

Drug-induced liver injury (DILI) represents liver damage from various therapeutic drugs. Antimicrobials are among the most common causes of DILI. We report a case of hepatic toxicity due to Trimethoprim-sulfamethoxazole (TMP-SMX) in a patient who underwent renal transplantation. Diagnosis has been made after a careful history taking, exclusion of competing etiologies and reversal of biochemical abnormalities after withdrawal of the antibiotic. TMP-SMX liver toxicity is well known but remains unpredictable and is rarely reported.

[Massive iatrogenic haemothorax treated by lidocaïne-adrenaline intercostal injection]. / Hémothorax iatrogène massif jugulé par injection intercostale de lidocaïne-adrénaline.

INTRODUCTION: Massive haemothorax is a relatively rare complication of thoracocentesis or the placement of tube thoracostomy. It is principally caused by intercostal vessel injury. The therapeutic approach consists in pleural drainage and sometimes thoracotomy for haemostasis. CASE REPORT: We describe a frail 72 year old patient, who developed a massive haemothorax occurring after a tube thoracostomy placing, persisting despite second pleural drainage, and complicated by deep haemodynamic shock. He was considered to have a very high risk of mortality if surgery was undertaken. Haemorrhage was totally stopped after intercostal instillation of lidocaïne-adrenaline. CONCLUSION: This case report suggests a role for pleural vasoconstrictor injection as initial treatment in case of persistent pleural haemorrhage caused by intercostal vessel injury.

[Agents and consequences of nosocomial infections in a Lebanese university hospital. Retrospective study over a two-year period]. / Agents et conséquences des infections nosocomiales dans un centre hospitalier universitaire libanais. Etude rétrospective sur 2 ans.

OBJECTIVES: Study the common sites of nosocomial infection, pathogens and antibiotic resistance in a university hospital. METHOD: Retrospective study during 1997 and 1998. RESULTS: One hundred eighty nosocomial infections were recorded in 154 patients. The incidence was 1.3 per 1 000 patient-days. Pneumonia was the second most frequent type of nosocomial infections after urinary tract infection, but caused the highest mortality. Gram-negative bacteria were the predominant agents (81%) with a major antibiotic resistance. CONCLUSION: A strict application of the preventive measures and surveillance program is warranted to control outbreaks of these infections.

Renal artery pseudoaneurysm after blunt abdominal trauma.

Renal artery pseudoaneurysms are rare after blunt abdominal trauma; only 11 cases have been previously reported. Pseudoaneurysms are caused by decelerating injuries of the renal artery after major falls or automobile accidents. Patients may be asymptomatic for many years, and the pseudoaneurysm may expand and rupture before diagnosis or treatment. The patients in four untreated cases died. The diagnosis of renal artery pseudoaneurysm can be made by Doppler sonography, computerized tomography, renal perfusion imaging, or contrast angiography. Treatment requires either surgical or percutaneous intervention. Renal salvage was possible in five of the seven patients treated. We report two additional patients with successful outcomes after surgical intervention.
