Surgical practice in rural communities: challenges and opportunities

I have attempted to point out some problems that face the surgeon in a rural practice as well as some of the advantages of living in a rural community. Surgical residents may find that a career choice in rural surgery merits their attention and consideration because the apparent obstacles can be readily overcome, and practice in a rural area can be intellectually and professionally challenging and rewarding.     

The impact of patient delay and physician delay on the outcome of laparoscopic cholecystectomy for acute cholecystitis

BACKGROUND: Laparoscopic cholecystectomy is now used in the management of acute cholecystitis. Under these circumstances unfavorable conditions may result in conversion and complications. Information about these conditions may help in planning the laparoscopic approach or in proceeding directly to open cholecystectomy. This study was initiated to evaluate perioperative factors associated with conversion and complications of laparoscopic cholecystectomy in acute cholecystitis. Special attention was paid to the duration of complaints until surgery, to the delay on the part of the patient, and to the delay on the part of the physician. METHODS: Between January 1994 and December 1997, we attempted to perform laparoscopic cholecystectomy on 348 patients with acute cholecystitis. All perioperative data were collected on standardized forms. RESULTS: There were 182 cases (52%) of acute uncomplicated cholecystitis, 90 (26%) of gangrenous cholecystitis, 33 of hydrops (9.5%), and 43 of empyema of the gallbladder (12.5%). Seventy six patients (22%) needed conversion to open cholecystectomy and complications occurred in 57 cases. Advanced cholecystitis was associated with significant patient delay (P = 0.01), and it had a significantly higher conversion rate (39%) compared with early cholecystitis (14.5%); (P <0.00001). Conversion rates were also associated with male gender (P = 0.0017), a history of biliary disease (P = 0.0085), and a patient delay of >48 hours (P = 0.028). The total and infectious complication rates were associated with an age older than 60 years (P = 0.023 and 0.007, respectively) and male gender (P = 0.026 and 0.014, respectively). CONCLUSIONS: In acute cholecystitis, patient delay is associated with a high conversion rate. Early timing of laparoscopic cholecystectomy tends to reduce the conversion rate, as well as the total and the infectious complication rates. Male gender, a history of biliary disease, and advanced cholecystitis are associated with conversion. Male and older patients are associated with a high total and infectious complication rates.     

Effects of single intravenous doses of recombinant human interleukin-10 on subsets of circulating leukocytes in humans

Recombinant human interleukin-10 (rhIL-10) is a potent and specific immunomodulatory agent which inhibits endotoxin-stimulated pro-inflammatory cytokine production by monocytes, blocks T-lymphocyte activation by antigen presenting cells, and modulates T(H)1/T(H)2 balance in immune responses. In previous clinical trials, rhIL-10 administered to healthy volunteers induced rapid and transient elevations of neutrophil and monocyte counts and reductions of lymphocyte counts in addition to suppression of endotoxin-stimulated whole blood cytokine synthesis. We sought to better characterize the effects of rhIL-10 on immunophenotypically defined subsets of circulating leukocytes that could be relevant to its immunomodulatory effects. Healthy volunteers were given single doses of 10 microg/kg rhIL-10 (n = 8) or equivalent placebo (n = 4) by intravenous injection. Significant changes of circulating leukocytes included transiently increased neutrophils and monocytes with parallel increases of CD33+ and CD14+ cells. Total lymphocytes as well as total CD3+, CD3+/CD4+ and CD3+/CD8+ cells transiently decreased. Mean fluorescence intensity of CD11a (integrin alpha-chain subunit of lymphocyte function antigen-1, LFA-1) on lymphocytes transiently but significantly decreased, suggesting a mechanism for transient alteration of lymphocyte trafficking. In addition, mean fluorescence intensity of HLA-DR (major histocompatibility class II) on CD14+ cells (predominantly monocytes) transiently but significantly decreased, implying a possible alteration of antigen presenting function. Further study will be required to elucidate the immunomodulatory roles and potential clinical significance of these hematologic changes in therapeutic trials of rhIL-10 in patients with chronic inflammatory and autoimmune diseases.     

Complications following operative treatment of primary malignant bone tumours in the pelvis.

AIM: To report the complication rates of limb-salvage reconstruction in the pelvis. Detailed analyses about the type, treatment and outcome of post-operative complications, various reconstruction options are presented. METHODS: Factors that might influence the occurrence of complications were evaluated of 50 consecutive surgically treated patients. RESULTS: The mean follow-up was 57 months. Limb-salvage procedures were used in 42/50 patients, amputations in 8/50 patients. After limb-salvage procedures complications occurred in 32/42 patients, after hemipelvectomy in 6/8 patients. The 1 and 5-year overall survival rate was 92 and 68%, respectively. CONCLUSION: There is a high complication rate in reconstructive techniques using hemipelvic autografts and/or allografts. These procedures are appropriate only in well selected patients. The complication rates following endoprosthetic reconstruction are comparably low.     

Primary malignant tumours of bone and soft tissue in the elderly.

AIMS: This study reports outcome, functional results and quality of life of 45 elderly patients with age over 70 after surgery for primary malignant bone and soft tissue tumours. METHODS: There were 24 primary malignant bone tumours and 21 soft tissue sarcomas. The most frequent diagnoses were: chondrosarcoma, malignant fibrous histiocytoma and liposarcoma. Local tumour resection with and without osteosynthesis, endoprostheses, and amputations had been performed for surgery. The patients were prospectively followed in a tumour register. RESULTS: Complication and revision rate, functional outcome using the Musculoskeletal Tumor Society score, 5-year survival rate, median survival time and quality of life according to the Life Satisfaction Index A and the global health and quality-of-life scale of the QLQ-C30 revealed results that are only slightly inferior to those reported in younger tumour patients. CONCLUSIONS: The results of this study generally justify even extensive tumour surgery in the elderly patient over 70 although outcomes are not quite as good as those reported for younger adults. However, especially in the old patient indications like general condition and comorbidity should be given due consideration before any decision is made on whether surgery should be performed and if so what surgical technique should be applied.     

What is the difference between squamous cell carcinoma and adenocarcinoma of the cervix? A matched case–control study

The objective of this study was to investigate the efficacy of treatment strategies in patients with adenocarcinoma (AC) of the cervix and compare it with those with squamous cell carcinoma (SCC) of the cervix. Women with FIGO (1994) stage IB1 AC, especially pathologic tumor size of 2-4 cm, treated with class III hysterectomy, were compared with those with SCC treated with comparable strategy in a case-controlled study. Eighty patients (20 cases, 60 controls) were analyzed. Lymphvascular space invasion (P = 0.01) and lymph node metastasis (P = 0.07) were more frequent in patients with SCC than in those with AC. However, there was no significant difference in depth of stromal invasion (P = 0.51) and invasion of the parametrium (P = 0.44) between two groups. And there was also no statistically significant difference in disease-free survival (P = 0.86) and overall survival (P = 0.89) between two groups. Primary radical surgery followed by adjuvant therapy, same as for SCC, would be acceptable for AC with pathologic tumor size of 2-4 cm. Although it was difficult to determine whether AC recurred more systemically, more effective treatment strategies than those currently available for AC should be considered to reduce the systemic recurrence.     

Tear of the distal biceps branchii tendon: A new method of ultrasound evaluation

Tear of the distal biceps brachii tendon is an uncommon injury. Ultrasound evaluation of the distal tendon using an anterior approach is often difficult because of technical factors. We describe a new method of ultrasound evaluation of the distal biceps tendon insertion. This involves a posterior approach with the forearm pronated. With pronation of the forearm, the radial tuberosity faces posteriorly, bringing the distal biceps tendon insertion into view. A surgically proven case of distal biceps tendon tear is presented to illustrate our technique.     

Achilles tendinopathy after treatment with fluoroquinolone

Fluoroquinolone antibiotic therapy is a recognized but poorly understood cause for Achilles tendinopathy. We report here a patient who developed bilateral partial Achilles tendon tears as a result of fluoroquinolone therapy. Ultrasound and MRI were both useful in identifying and distinguishing between Achilles tendinosis and tendon rupture. The current published literature on this problem was also reviewed.     

Versatility in multiple mini-interview implementation: Rater background does not significantly influence assessment scoring

Abstract

The medical school admissions process seeks to assess a core set of cognitive and non-cognitive competencies that reflect professional readiness and institutional mission alignment. The standardized format of multiple mini-interviews (MMIs) can enhance assessments, and thus many medical schools have switched to this for candidate interviews. However, because MMIs are resource-intensive, admissions deans use a variety of interviewers from different backgrounds/professions. Here, we analyze the MMI process for the 2018 admissions cycle at the VCU School of Medicine, where 578 applicants were interviewed by 126 raters from five distinct backgrounds: clinical faculty, basic science faculty, medical students, medical school administrative staff, and community members. We found that interviewer background did not significantly influence MMI evaluative performance scoring, which eliminates a potential concern about the consistency and reliability of assessment.
