Background: Pain following hip fracture and internal fixation is a major factor during the treatment of elderly patients on rehabilitation programs. A proactive pain management program was instituted in our geriatric rehabilitation ward in 2005.

Objectives: To compare retrospectively two groups of patients, one before and one after implementation of the proactive pain management program.

Methods: The study group comprised 67 patients and the control group 77 patients. Pain in the study group was evaluated daily by the visual analogue scale (VAS) and the outcome of the rehabilitation process by the Functional Independence Measure (FIM). During the study period (2003–2006) no changes were made in the rehabilitation team, methods or facilities other than introduction of the pain control program. We compared the FIM scores between admission and discharge in both groups.

Results: Improvement in FIM scores between admission and discharge was significantly higher in the study group than in the control group (11.07 ± 7.9 vs. 8.4 ± 7.3, P < 0.03). There was no significant difference between the average lengths of stay.

Conclusions: These data support the view that the proactive monitoring of pain in surgical hip fracture patients is associated with a better outcome of the rehabilitation process.

Background: Major changes in the evaluation and treatment of curable colorectal cancer (CRC) have emerged in the last two decades. These changes have led to better patient outcome over time.

Objectives: To evaluate the impact of these changes as reflected in the difference in long-term outcome of a consecutive group of recently laparoscopically operated curable CRC[1] patients and a consecutive group of patients operated 20 years earlier in the same department.

Methods: Data of the new group were taken from our prospectively collected data of patients who underwent elective laparoscopic surgery for CRC in recent years. Data regarding patients operated on 20 years ago were retrieved from previous prospectively collected data on the long-term survival of CRC patients operated in the same department.

Results: The recently operated group comprised 203 patients and the previous group 199 patients. Perioperative mortality was 0.5% in the new group versus 1.5% in the old group (not significant). There were more early-stage and more proximal tumors in the recently operated group. A Kaplan-Meier 5-year survival analysis revealed no difference between stage I patients of the two groups. However, there was a significant increase in 5-year survival in the new group for stage II (85% vs. 63%, P = 0.004) and for stage III patients (57% vs. 39%, P = 0.01). This trend was maintained after removing the rectal cancer patients from the calculated data.

Conclusions: We have demonstrated improved survival for stage II and III CRC patients over a 20-year period in the same medical center. This change most likely reflects advances both in imaging techniques leading to more accurate staging and in adjuvant treatments.

Background: Meningiomas are frequently detected incidentally. Their natural history has not yet been established because it is difficult to predict the growth pattern. Therefore, the management, after the radiological diagnosis, is still controversial.

Objectives: To evaluate the clinical outcome and growth rate of conservatively treated meningiomas at our tertiary center, identify prognostic factors of tumor growth, and suggest guidelines based on the available data and our experience.

Methods: We reviewed the clinical records of 56 patients with 63 untreated meningiomas. Most were diagnosed incidentally. Clinical features and imaging findings at diagnosis and during follow-up were compared between growing and non-growing tumors. Potential patient- and tumor-related predictive factors for growth were analyzed.

Results: The study group included 46 women (52 meningiomas) and 10 men (11 meningiomas) aged 39–83 years. Mean tumor size was 18 ± 11 mm (range 3–70 mm) at diagnosis and 22 ± 11 mm (range 8–70 mm) at last follow-up; mean follow-up time was 65 ± 34 months (range 15–152 months). During follow-up 24 tumors (38%) grew at a rate of 4 mm per year; none became symptomatic. Only two prognostic factors were statistically significantly associated with low growth rate: older age and tumor calcifications.

Conclusions: Given our finding of a low growth incidence of meningiomas in the elderly, we support conservative management in patients aged 70 years or older. Calcifications into the meningioma are also indicative of slow growth, suggesting a conservative strategy. Surgery is recommended in younger patients in whom tumor growth occurs more often and a longer follow-up is necessary.

Background: One of the major concerns in performing nephron-sparing surgery (NSS) for renal cell carcinoma (RCC) is the risk of tumor recurrence.

Objectives: To assess the rate, predictors and mechanisms of oncological failure in patients after NSS[1] for renal cancer.

Methods: Between 1993 and 2008 NSS was performed in 229 patients via flank incision. Only patients without metastases at diagnosis and minimal 12 months follow-up were included in the outcome analysis.

Results: During a mean follow-up of 45 ± 34 months (range 6–168 months) tumor recurrence was observed in 13 patients (5.6%). Mean follow-up time for detection of oncological failure was 51 months (range 6–132 months).  All patients with oncological failure were males, with a mean age of 61 years (median 58, range 51–74 years). The average size of the enucleated lesion was 5 cm (range 4–7 cm). Intraoperative frozen sections as well as postoperative final pathological examination of the surgical margins were negative in all recurrent cases. Mechanisms of recurrence were distant metastases (n=4), surgical scar implantation (n=2), perirenal fat recurrence (n=2), local renal recurrence at the surgical site (n=1), and new renal lesions (n=4). Predictors of oncological failure included warm ischemia time (P = 0.058), tumor size (P = 0.001), tumor location (central versus peripheral) (P = 0.015), and multifocality (P = 0.001).

Conclusions: Distant dissemination, seeding during surgery, residual disease and new growth are the mechanisms responsible for cancer relapse. Large central lesions, long warm ischemia time and multifocality were significant predictors of oncological failure.

Background: On-site cardiac surgery is not widely available in developing countries despite a high prevalence of coronary artery disease.

Objectives: To analyze the safety, feasibility and cost-effectiveness of transradial percutaneous coronary intervention without on-site cardiac surgery in a community hospital in a developing country.

Methods: Of the 174 patients who underwent PCI[1] for the first time in our center, we analyzed two groups: stable coronary disease and acute myocardial infarction. The primary endpoint was the rate of complications during the first 24 hours after PCI. We also analyzed the length of hospital stay and the rate of hospital readmission in the first week after PCI, and compared costs between the radial and femoral approaches.

Results: The study group comprised 131 patients with stable coronary disease and 43 with acute MI[2]. Among the patients with stable coronary disease 8 (6.1%) had pulse loss, 12 (9.16%) had on-site hematoma, and 3 (2.29%) had bleeding at the site of the puncture. Among the patients with acute MI, 3 (6.98) had pulse loss and 5 (11.63%) had bleeding at the site of the puncture. There were no cases of atriovenous fistula or nerve damage. In the stable coronary disease group, 130 patients (99%) were discharged on the same day (2.4 ± 2 hours). In the acute MI group, the length of stay was 6.6 ± 2.5 days with at least 24 hours in the intensive care unit. There were no hospital readmissions in the first week after the procedure. The total cost, which includes equipment related to the specific approach and recovery room stay, was significantly lower with the radial approach compared to the femoral approach (US$ 500 saving per intervention).

Conclusions: The transradial approach was safe and feasible in a community hospital in a developing country without on-site cardiac surgery backup. The radial artery approach is clearly more cost effective than the femoral approach.

Background: Injury to patent grafts or cardiac chambers may occur during reoperation after coronary artery bypass grafting. Preoperative spatial localization of bypass grafts with computed tomography may improve the safety of these procedures.

Objectives: To characterize patients who undergo CT before repeat operations after previous coronary artery bypass grafting, and evaluate its benefit in terms of surgical outcome.

Methods: We compared 28 patients who underwent cardiac gated CT angiography before reoperation (CT group) to 45 re-do patients who were not evaluated with CT (no‑CT group).

Results: The two groups were similar in most preoperative and operative characteristics. The CT group, however, included more patients with patent saphenous vein grafts and fewer with emergency operations, acute myocardial infarction and need for intraaortic balloon pump support. During mid-sternotomy, there was no injury to grafts in the CT group, while there were two patent grafts and three right ventricular injuries in the no-CT group. There was no significant difference in perioperative mortality (3.6% vs. 8.9%). The overall complication rate in the CT group was 21.4% compared to 42.2% in the no‑CT group (P = 0.07). The only independent predictors of postoperative complications were diabetes mellitus, preoperative stroke and preoperative acute MI[1].

Conclusions: The patency and proximity of patent grafts to the sternum are well demonstrated by multidetector CT and may provide the surgeon with an important roadmap to avoid potential graft injury. A statistical trend towards reduced complications rate was demonstrated among patients who underwent CT angiography before their repeat cardiac operation. Larger series are required to demonstrate a statistically validated complication-free survival benefit of preoperative CT before repeat cardiac surgery.

Background: Sporadic abdominal desmoid tumors are rare and data on these tumors as a distinct disease entity are lacking. Previous abdominal surgery, trauma, pregnancy and estrogen intake are considered risk factors. Although desmoidsare benign, invasion and a high recurrence rate are common.

Objectives: To evaluate outcomes of surgery for this rare disease.

Methods: Since 1995, 16 patients with pathologically confirmed desmoid tumor were operated on in our center. All familial adenomatous polyposis patients were excluded. A retrospective analysis of data was performed.

Of the 16 patients 12 (75%) were females. Mean age was 40.5 years (range 24-70). Thirteen patients were symptomatic and 3 were incidentally diagnosed. All patients presented with an isolated mass; 7 (50%) originated in the abdominal wall, 6 (37.5%) were retroperitoneal and 3 were (18.8%) mesenteric. All tumors except one were completely excised. Morbidity was low with no mortality. One patient was reoperated due to involved margins. None of the patients had recurrence within a median follow-up of 64 months (range 5-143).

Conclusions: The perception of sporadic abdominal desmoids as tumors with a high recurrence rate (20-70%) is probably incorrect. Adequate surgery with wide margins leads to a very low recurrence rate; cure is a legitimate goal.
