Abdominal musculature abnormalities as a cause of groin pain in athletes. Inguinal hernias and pubalgia.

There has been increasing interest within the European sports medicine community regarding the etiology and treatment of groin pain in the athlete. Groin pain is most commonly caused by musculotendinous strains of the adductors and other muscles crossing the hip joint, but may also be related to abdominal wall abnormalities. Cases may be termed "pubalgia" if physical examination does not reveal inguinal hernia and there is an absence of other etiology for groin pain. We present nine cases of patients who underwent herniorrhaphies for groin pain. Two patients had groin pain without evidence of a hernia preoperatively (pubalgia). In the remaining seven patients we determined the presence of a hernia by physical examination. At operation, eight patients were found to have inguinal hernias. One patient had no hernia but had partial avulsion of the internal oblique fibers from their insertion at the public tubercle. The average interval from operation to return to full activity was 11 weeks. All patients returned to full activity within 3 months of surgery. One patient had persistent symptoms of mild incisional tenderness, but otherwise there were no recurrences, complications, or persistence of symptoms. Abnormalities of the abdominal wall, including inguinal hernias and microscopic tears or avulsions of the internal oblique muscle, can be an overlooked source of groin pain in the athlete. Operative treatment of this condition with herniorrhaphy can return the athlete to his sport within 3 months.     

Associations between patient report of symptoms and anatomic impairment visible on lumbar magnetic resonance imaging

STUDY DESIGN: A cross-sectional study comparing the relationship of symptoms with anatomic impairment visible on lumbar magnetic resonance imaging in 408 symptomatic subjects. OBJECTIVE: To determine how various anatomic impairments, including the magnitude and location of nerve compression visible on lumbar magnetic resonance imaging, are associated with patient reports of pain, weakness, and dysesthesia. SUMMARY AND BACKGROUND DATA: Anatomic impairments of the intervertebral disc, radicular canal, and associated soft tissues are prevalent in people with and those without low back pain or lower extremity radiculopathy. This has led to confusion in differentiating between symptom generators and benign variation visible on lumbar magnetic resonance imaging. Recent literature has suggested that the presence of nerve compression is an important finding in the prediction of symptoms. However, the threshold for meaningful nerve compression has not been described. METHODS: In this study, 408 participants undergoing a diagnostic workup for low back pain, radiculopathy, and/ or completed a survey and pain drawing. Participants underwent standardized lumbar magnetic resonance imaging using a 1.5-T scanner. Two classification systems describing the spatial distribution of symptoms were developed. An additional system to quantify the magnitude of nerve and thecal sac compression was created. All systems were assessed for reliability, after which comparisons among variables were performed using Chi2 as well as simple and multiple logistic regression analysis. RESULTS: The reliability coefficients for categorizing patients on the basis of pain drawing ranged from 0. 75 to 0.88. The S1-S2 segmental distribution was the most commonly reported location of symptoms, followed by L4-L5. The most common magnetic resonance imaging diagnosis was "unremarkable," followed by "disc impairment without nerve compression." Disc extrusion was present in 10.8% of participants. The reliability of classifying nerve compression visible on magnetic resonance imaging ranged from 0.27 to 1. Nerve compression was present in 37% of participants, and 18% had severe nerve compression. There were no significant associations between segmental distribution of symptoms and the presence of anatomic impairment. However, according to a collapsed classification scale, severe nerve compression and disc extrusion were predictive of pain distal to the knee (odds ratios, 2.72 and 3. 34). The self-report of weakness was associated mildly with severe nerve compression and disc extrusion, but not with other findings. Magnetic resonance imaging findings did not predict self-reports of dysesthesia. CONCLUSIONS: The presence of disc extrusion and/or ipsilateral, severe nerve compression at one or multiple sites is strongly associated with distal leg pain. Mild to moderate nerve compression, disc degeneration or bulging, and central spinal stenosis are not significantly associated with specific pain patterns. Although segmental distributions of pain can be determined reliably from pain drawings, this finding alone is of little use in predicting lumbar impairment. The self-report of lower extremity weakness or dysesthesia is not significantly related to any specific lumbar impairments.

Liver metastases from breast cancer: long-term survival after curative resection

BACKGROUND: Liver metastases from breast cancer are associated with a poor prognosis (median survival < 6 months). A subgroup of these patients with no dissemination in other organs may benefit from surgery. Available data in the literature suggest that only in exceptional cases do these patients survive more than 2 years when given chemohormonal therapy or supportive care alone. We report the results of liver resection in patients with isolated hepatic metastases from breast cancer and evaluate the rate of long-term survival, prognostic factors, and the role of neoadjuvant high-dose chemotherapy. PATIENTS AND METHODS: Over the past decade, 17 women underwent hepatic metastectomy with curative intent for metastatic breast cancer. The follow-up was complete in each patient. The median age at the time breast cancer was diagnosed was 48 years. Neoadjuvant high-dose chemotherapy (HDC) with hematopoietic progenitor support was used in 10 patients before liver resection. Perioperative complications, long-term outcome, and prognostic factors were evaluated. RESULTS: Seven of the 17 patients are currently alive, with follow-up of up to 12 years. Four of these patients are free of tumors after 6 and 17 months and 6 and 12 years. The actuarial 5-year survival rate is 22%. One patient died postoperatively (mortality rate, 6%) of carmustine-induced fibrosing pneumonitis. There was no further major morbidity in the other patients. The liver was the primary site of recurrent disease after liver resection in 67% of the patients. Patients in whom liver metastases were found more than 1 year after resection of the primary breast cancer had a significantly better outcome than those with early (< 1 year) metastatic disease (P = .04). The type of liver resection, the lymph node status at the time of the primary breast cancer resection, and HDC had no significant impact on patient survival in this series. CONCLUSIONS: Favorable 22% long-term survival can be achieved with metastasectomy in this selected group of patients. Careful evaluation of pulmonary toxicity from carmustine and exclusion of patients with extrahepatic disease are critical. Improved survival might be achieved with better selection of patients and the use of liver-directed adjuvant therapy.     

Laparoscopic splenectomy in children with hematological disorders: preliminary experience at the Children's Hospital of New Orleans

Minimally invasive surgery has recently gained acceptance as the surgical approach of choice for a variety of surgical disorders in children. Although traditional open surgery is still regarded as the standard approach for a splenectomy in children when necessary for hematologic disorders a few cases of successful laparoscopic splenectomy (LS) have been reported. We present our initial 11 cases of LS in children assessing surgical outcome. Eleven patients ages 2 through 15 years underwent LS between June of 1996 and July of 1999 at the Children's Hospital of New Orleans. Indications for surgery included idiopathic thrombocytopenic purpura, congenital spherocytosis, and hemolytic anemia. In all patients the diameter of the spleen was less than 15 cm. Surgical outcome was assessed according to the following parameters: operative time, postoperative length of stay, postoperative morbidity, and cosmetic results. Data were accumulated on the basis of retrospective chart review. LS was completed in all 11 patients. Postoperative morbidity was minimal and the median postoperative stay was 2.4 days (range 1-5). Mean operative time was 3 hours and 10 minutes (range 1.5-7 hours) with the last six procedures completed in an average of just over 2 hours. Intravenous analgesia was discontinued in <48 hours in all patients. Cosmetic results were judged excellent in all cases. We conclude that LS was safe in children with certain hematologic disorders. Adequate selection of patients, appropriate preoperative preparation of patients, meticulous surgical technique, and careful postoperative care were key factors in obtaining the same long-term results as with open surgery.     

Randomized phase III study of docetaxel compared with paclitaxel in metastatic breast cancer.

PURPOSE: This randomized, controlled, multicenter, open-label, phase III study compared docetaxel versus paclitaxel in patients with advanced breast cancer that had progressed after an anthracycline-containing chemotherapy regimen. PATIENTS AND METHODS: Patients (n = 449) were randomly assigned to receive either docetaxel 100 mg/m2 (n = 225) or paclitaxel 175 mg/m2 (n = 224) on day 1, every 21 days until tumor progression, unacceptable toxicity, or withdrawal of consent. RESULTS: In the intent-to-treat population, both the median overall survival (OS, 15.4 v 12.7 months; hazard ratio [HR], 1.41; 95% CI, 1.15 to 1.73; P = .03) and the median time to progression (TTP, 5.7 months v 3.6 months; HR, 1.64; 95% CI, 1.33 to 2.02; P < .0001) for docetaxel were significantly longer than for paclitaxel, and the overall response rate (ORR, 32% v 25%; P = .10) was higher for docetaxel. These results were confirmed by multivariate analyses. The incidence of treatment-related hematologic and nonhematologic toxicities was greater for docetaxel than for paclitaxel; however, quality-of-life scores were not statistically different between treatment groups over time. CONCLUSION: Docetaxel was superior to paclitaxel in terms of OS and TTP. ORR was higher for docetaxel. Hematologic and nonhematologic toxicities occurred more frequently in the docetaxel group. The global quality-of-life scores were similar for both agents over time.     

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.
