Squamous cell carcinoma lower lip - an experience with Karapandzic technique

Carcinoma of the lip is a common cancer of head and neck area. It occurs frequently on the lower lip of middle-aged and elderly males who have a history of chronic sun exposure. Surgical excision and radiotherapy are regarded as equally effective treatment options, but preferred method is surgical excision. Karapandzic technique provides myoneurovascular pedicled advancement flap for reconstruction of the defect after surgical excision. It is a simple and safe technique, functionally and esthetically, sacrifices little tissue, heals rapidly and is effective for repair of defects covering 1/3 to 4/5 of the lower lip. We report a 62 years male who presented with a large, fungating, pus-discharging and tender mass of lower lip. Biopsy confirmed squamous cell carcinoma. Tumor was excised and defect was reconstructed using Karapandzic technique. Patient remained asymptomatic during follow-up visits.     

Evaluation of the optimal preemptive dose of gabapentin for postoperative pain relief after lumbar diskectomy: a randomized, double-blind, placebo-controlled study

We evaluated the optimal preemptive dose of gabapentin for postoperative pain relief after single-level lumbar diskectomy and its effect on fentanyl consumption during the initial 24 hours in a randomized, double-blinded, placebo-controlled study in 100 patients with American Society of Anesthesiologists physical status I and II. Patients were divided into five groups to receive placebo or gabapentin 300, 600, 900, or 1200 mg 2 hours before surgery. After surgery, patients were transferred to the postanesthesia care unit (PACU). A blinded anesthesiologist recorded the pain scores at time points of 6, 12, 18, and 24 hours in the PACU on a Visual Analog Scale (VAS; 0-10 cm) at rest. Patients received patient-controlled analgesia (fentanyl 1.0 mug/kg on each demand with lockout interval of 10 minutes); total fentanyl consumption during initial 24 hours was recorded. Data were entered into the statistical software package SPSS 9.0 for analysis (one-way analysis of variance and Student-Newman-Keuls test). Patients who received gabapentin 300 mg had significantly lower VAS score at all time points. They consumed less fentanyl (patients who received placebo processed 1217.5 +/- 182.0 versus 987.5 +/- 129.6 mug; P < 0.05). Patients who received gabapentin 600, 900, and 1200 mg had lower VAS scores at all time points than patients who received gabapentin 300 mg (P < 0.05). Increasing the dose of gabapentin from 600 to 1200 mg did not decrease the VAS score, nor did the increasing dose of gabapentin significantly decrease fentanyl consumption (702.5, 635, and 626.5 microg). Thus, gabapentin 600 mg is the optimal dose for postoperative pain relief following lumbar diskectomy.     

The effect of temporary hemiepiphyseal stapling on the growth plate: a radiologic and immunohistochemical study in rabbits

The purpose of this study was to investigate the effect of temporary hemiepiphyseal stapling on the bone geometry and proliferative activity of the physis in immature rabbits. Proximal medial epiphyseal stapling of the right tibia was performed in 46 6-week-old New Zealand white rabbits. The rabbits were assigned randomly into two groups. In group 1, the staples were inserted extraperiosteally and the rabbits were killed at the end of 3 weeks. In group 2, the staples were fixed subperiosteally (group IIA) or extraperiosteally (group IIB), the staples were removed at the end of 3 weeks, and the rabbits were killed at the end of 6 weeks. The articular line-diaphysis angle (ALDA) was significantly increased with 3 weeks of stapling. After the removal of staples, while ALDA continued to worsen in group IIA, it improved in group IIB. Bone was observed to bridge the physis in group IIA. However, the proliferative activity of the physis continued. Temporary hemiepiphyseal stapling is a safe and effective method for control of physeal growth of long bones before skeletal maturity. However, it is of paramount importance not to disturb the periosteum during stapling.     

Coronary bypass procedures in patients with renal artery stenosis

BACKGROUND AND AIM OF THE STUDY: We present our experience on patients with renal artery stenosis undergoing myocardial revascularization procedures. METHODS: Eighteen patients with varying degrees of renal artery stenosis were operated for coronary artery bypass grafting between 1996 and 2003. The overall incidence was 0.15%. There were nine male and nine female patients with a mean age of 62 +/- 8.2 (40-72 years). Four had bilateral and eight had significant unilateral (>50%) renal artery stenoses. Preoperatively, three patients had renal arterial intervention (stenting), and one patient was on hemodialysis. The mean preoperative creatinine value was 2.6 +/- 2.7 mg/dL (range 0.7 to 9.3). The patients were followed medically: two patients underwent off-pump coronary bypass grafting and the others were operated on-pump. RESULTS: There was only one mortality and two patients required hemodialysis postoperatively. The postoperative mean creatinine values were 3.4 +/- 4.9 mg/dL (range 1.0 to 12.5). No electrolyte imbalances were noted except that one case revealed a transient metabolic acidosis. Five patients required inotropic support with dopamine and two needed diuretic infusions. Only five patients demonstrated a refractory hyper tensive period postoperatively. CONCLUSIONS: The concomitant correction of renal artery stenosis with CABG is usually not necessary, but the principles for renovascular diseases must be kept in mind and individually oriented strategies must be planned.     

Best evidence continuous medical education

Health care professionals need to approach their profession with a view to life long learning. They need to develop a strategy to meet their learning needs in a reflective and effective manner. Continuous medical educational (CME) is the traditional tool for learning and updating knowledge. Most of them are in the forms of courses, conferences, journal clubs and workshops. They are mostly didactic sessions and evidence suggests that they are not effective to improve the clinical skills and attitude. Systematic review of teaching evidence-based medicine shows that interactive and clinically integrated learning is the most effective form of learning. It enhances knowledge and skills. Professionals should view CME in a holistic manner in the context of continuous professional development (CPD) and even in the wider concept of knowledge translation, which encompasses both CME and CPD. e Learning is one of the most important forms of non-traditional CME. It provides an efficient and increasingly interactive delivery system that can handle complex and layered information. More work needs to be done to see its effectiveness for practising clinicians.     

Left Main Myocardial Infarction in a Healthy Young Male—A Case Report

Acute left main coronary artery occlusion is a catastrophic and mostly fatal event. Patients may present with sudden death or cardiogenic shock. Intra-aortic balloon pump support and emergency revascularization is indicated to preserve the left ventricular function. We describe a case of left main thrombus in a health 24-year-old young male with no risk factors for coronary atherosclerosis.

Functional and chronic anorectal and pelvic pain disorders

Several organic and functional disorders of the urinary bladder, reproductive tract, anorectum, and the pelvic floor musculature cause pelvic pain. This article describes functional disorders in which chronic pelvic and anorectal pain cannot be explained by a structural or other specified pathology. Currently, these functional disorders are classified into urogynecologic conditions or cystitis and painful bladder syndrome, anorectal disorders, and the levator ani syndrome. Although nomenclature suggests that these conditions are distinct, there is considerable overlap of their symptoms and these disorders have much in common.     

Use of the day 6 bone marrow to alter remission induction therapy in patients with acute myeloid leukaemia: a leukemia intergroup study

Patients with acute myeloid leukaemia who fail to show substantial bone marrow cytoreduction by day 6 of induction therapy enter complete remission (CR) less frequently than patients with good bone marrow leukaemic cytoreduction. The objective of the current study was to determine whether an increase in the intensity of therapy on days 8, 9 and 10 ('augmentation' of remission induction therapy) for patients with poor bone marrow cytoreduction detected in the day 6 bone marrow could improve the complete remission rate without increasing the number of toxic deaths. Patients from six centres were entered and treated with standard dose ara-C for 7 or 10 d and an anthracycline for the first 3 d. Patients aged less than 60 years and with greater than 30% bone marrow biopsy cellularity or greater than 10% abnormal cells on the aspirate obtained 6 d after the start of therapy were augmented with cytosine arabinoside 3 g/m2 every 12 h on days 8, 9 and 10. Therapy was augmented in 116 of the 252 patients less than 60 years. There was a highly statistically significant difference between augmented and nonaugmented patients (P less than 0.001) for the per cent biopsy cellularity and per cent abnormal cells in the day 6 marrow. The CR rate for augmented patients was 69% and for nonaugmented patients 60% suggesting that augmentation therapy abrogated the prognostic significance of more extensive residual leukaemia in the day 6 bone marrow. The results suggest that augmentation of remission induction for patients with poor bone marrow cytoreduction detected 6 d after initiation of therapy, may salvage patients who are destined to fail remission induction because of resistant disease without producing excessive toxicity.
