Short-term effect of glucocorticoid injection into the superficial masseter muscle of patients with chronic myalgia: a comparison between fibromyalgia and localized myalgia.

The aim of this study was to investigate whether the treatment effect of intramuscular glucocorticoid injection differs between patients with fibromyalgia and those with localized myalgia of the masseter muscle concerning pain, tenderness to digital palpation, pressure pain threshold, pressure pain tolerance level, maximum voluntary occlusal force, or intramuscular temperature. Twenty-five patients with fibromyalgia and 25 patients with localized myalgia of the masseter muscle were first asked to assess their pain on a visual analogue scale; afterward, a routine clinical examination, including tenderness to digital palpation, was performed. For each patient, the pressure pain threshold, pressure pain tolerance level, and maximum voluntary occlusal force, as well as the intramuscular temperature, were recorded. Finally each patient received an injection of glucocorticoid. The examination and glucocorticoid treatment were repeated after approximately 2 weeks, and a follow-up was performed after another 5 weeks. In the fibromyalgia group, there was a reduced tenderness to digital palpation in response to the treatment. The localized myalgia group responded with a general improvement of symptoms as well as a significant reduction of pain intensity and tenderness to digital palpation. The results of this study indicate that patients with fibromyalgia and localized myalgia in many respects show a similar response to local glucocorticoid treatment.

Is the posterior belly of the digastric muscle palpable? A qualitative systematic review of the literature.

Palpation of the posterior belly of the digastric muscle in the postmandibular region is included in many study protocols and examination schemes of the masticatory system. The aim of the present investigation was to systematically search the dental/medical literature to find evidence for the palpability of this muscle. In August 2004, a systematic search was carried out using different electronic databases (PubMed, Cochrane Library, Web of Science, Japana Centra Revuo Medicina, MedPilot, Latin American and Caribbean Health Sciences, and three on-line databases of dental journals not listed currently in Medline), supplemented by manual search in the Austrian journal Stomatologie. Additional manual searches were carried out in the Journal of Orofacial Pain and Journal of Dental Research to identify pertinent abstracts of scientific congresses. One relevant hit was found in the Japanese database. The manual search showed one pertinent congress abstract. In both publications, the authors concluded that due to anatomical reasons the posterior belly of the digastric muscle was not palpable. Hence, evidence is lacking that the posterior digastric muscle is accessible to palpation. Because the postmandibular region is usually tender upon palpation, a high incidence of positive findings can be expected even among healthy subjects. This may lead to wrong clinical judgments, possibly provoking unnecessary diagnostic and therapeutic measures.

Clinical versus ultrasound examination of the thyroid gland in common clinical practice.

In a prospective series of 72 patients, clinical and ultrasonographic examination of the thyroid gland were compared in detail. Normal-sized lobes were differentiated from enlarged ones both by inspection and by palpation. When lobar size was assessed by palpation, the estimate was most clearly influenced by increase in width. The correlation between two examiners in lobe size assessment was significant. In the classification of thyroid disease as diffuse, solitary, or multinodular, clinical examination and ultrasonography correlated significantly. However, only one third of the clinically solitary nodules proved to be solitary by ultrasound examination. Of 77 separate nodules, 43 escaped detection on clinical examination. Of these 43, 14 nodules exceeded 2 cm in diameter. It is concluded that the use of ultrasonography frequently alters the primary evaluation of thyroid nodularity based on palpation.

Thyroid nodules: clinical effect of ultrasound-guided fine-needle aspiration biopsy.

Ultrasound (US)-guided fine-needle aspiration biopsy (FNA) was performed on 268 thyroid nodules (135 palpable, 133 nonpalpable) in 210 patients with various thyroid conditions; 62 nodules also had palpation-guided FNA. Surgical pathology was obtained in 67 malignant nodules and 32 benign nodules. Although the initial failure rate for palpation-guided FNA (12 of 62) was significantly higher than that for US-guided FNA (10 of 268) (p < 0.001), sensitivity (96%), specificity (91%), accuracy (94%), and positive (96%) and negative predictive values (91%) of US-guided FNA for malignancy (n = 99) were not significantly different from those (88%, 90%, 88%, 95%, and 75%, respectively) of palpation-guided FNA (n = 34) for those nodules where an adequate biopsy was obtained. US-guided FNA established a correct diagnosis in 20 of 22 patients with nonpalpable malignancy and in another nodule in the opposite thyroid lobe in 16 of 17 patients with thyroid malignancy. This procedure determined the correct cancer staging in 19 of 21 patients. US-guided FNA can reliably (1) select a patient who needs surgery and (2) avoid unnecessary surgery. This technique will help determine a cancer staging and institute an appropriate treatment.

Measuring engagement of the fetal head: validity and reproducibility of a new ultrasound technique.

OBJECTIVE: Fetal head engagement can be assessed by translabial ultrasound and has been shown to be predictive of delivery mode. We attempted to validate the technique by comparing ultrasound with abdominal and vaginal palpation. Reproducibility was tested in a blinded test-retest series. METHODS: In a prospective clinical study, 139 nulliparous women between 35 + 3 and 40 + 4 weeks' gestation were assessed by translabial ultrasound, abdominal palpation of the fetal head (n = 139) and vaginal examination (n = 112). Ultrasound was performed using two methods, with the symphysis pubis as reference. A test-retest series was performed in 90 women. RESULTS: Ultrasound of head engagement correlated strongly with abdominal palpation, full Bishop scores and vaginal assessment (all P < 0.001 for Kendall's tau-b). Intraclass correlation coefficients (n = 90) for the two methods were 0.75 and 0.92, signifying excellent interobserver agreement. Reproducibility was higher for the method using the central symphyseal axis as reference. CONCLUSION: Quantitation of head engagement by translabial ultrasound is highly reproducible and correlates strongly with clinical measures of head engagement. We are now undertaking a prospective study to assess the predictive value of this new parameter for intrapartum events.

Modern imaging techniques and ultrasound-guided aspiration cytology for the assessment of neck node metastases: a prospective comparative study.

Although palpation has proved to be an unreliable staging procedure, the indications for and the implications of more reliable radiologic staging methods for the neck in patients with a primary squamous cell carcinoma of the head and neck remain controversial. Only a very accurate imaging technique can replace neck dissection in clinical NO disease. This study compares the value of palpation with computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound (US) with or without guided aspiration cytology for neck node staging. One hundred and thirty-two patients with squamous cell carcinoma of the head and neck were examined radiologically before undergoing a total of 180 neck dissections as part of their treatment. CT, US and MRI proved to be significantly more accurate than palpation for cervical lymph node staging. The accuracy of US-guided aspiration cytology was significantly better than of any other technique used in this study. Modern imaging techniques are essential for appropriate assessment of neck node metastases. In view of advances in the accuracy of contemporary imaging, the need for elective treatment of the neck requires reappraisal.

Prospective, blinded comparison of laparoscopic ultrasonography vs. contrast-enhanced computerized tomography for liver assessment in patients undergoing colorectal carcinoma surgery.

PURPOSE: To prospectively and blindly compare intraoperative laparoscopic ultrasonography to preoperative contrast-enhanced computerized tomography in detecting liver lesions in colorectal cancer patients. Additionally, we compared conventional (open) intraoperative ultrasonography with bimanual liver palpation to contrast-enhanced computerized tomography in a subset of patients. METHODS: From December 1995 to March 1998, 77 consecutive patients underwent curative (n = 63) or palliative (n = 14) resections for colorectal cancer. All patients undergoing curative resections were randomized to either laparoscopic (n = 34) or conventional (n = 29) surgery after informed consent. All patients underwent contrast-enhanced computerized tomography, diagnostic laparoscopy, and laparoscopic ultrasonography before resection. In those patients who had conventional procedures, intraoperative ultrasonography with bimanual liver palpation was also done. All laparoscopic ultrasonography and intraoperative ultrasonography evaluations were performed by one of two radiologists who were blinded to the CT results. All hepatic segments were scanned using a standardized method. The yield of each modality was calculated using the number of lesions identified by each imaging modality divided by the total number of lesions identified. RESULTS: In 43 of the 77 patients, both the laparoscopic ultrasonography and CT scan were negative for any liver lesions. In 34 patients, a total of 130 lesions were detected by laparoscopic ultrasonography, CT, or both. When compared with laparoscopic ultrasonography, intraoperative ultrasonography with bimanual liver palpation identified one additional metastatic lesion and no additional benign lesions. laparoscopic ultrasonography identified two patients with mets who had negative preoperative contrast-enhanced computerized tomography. CONCLUSIONS: Laparoscopic ultrasonography of the liver at the time of primary resection of colorectal cancer yields more lesions than preoperative contrast-enhanced computerized tomography and should be considered for routine use during laparoscopic oncologic colorectal surgery.

Continuous pulse amplitude monitoring of infrainguinal bypass grafts in the first 24 postoperative hours.

To evaluate continuous pulse amplitude monitoring (CPAM) as a method for early postoperative graft surveillance following infrainguinal bypass surgery, a prospective observational study was carried out in 34 consecutive infrainguinal bypass grafts. CPAM tracings were compared with pre- and postoperative pulse palpation, ankle/brachial index (ABI) measurements, and pulse volume recordings (PVR). The utility of each method was defined by its ability to demonstrate graft patency in the first 24 hours. Pulse palpation was considered a useful monitoring tool if a postoperative pedal pulse was found in the absence of palpable preoperative pulses. The ABI qualified in this respect if a postoperative increase of at least 0.25 could be demonstrated; for PVR tracings an increase of at least one category was required. The utility of CPAM was established by an increase of at least 5 mm compared to the preoperative values. There were no early graft failures. We were therefore unable to calculate the ability of the studies to predict graft failure. The percentages (95% confidence limits) for which pulse palpation, ABI, and PVR were found capable of demonstrating graft patency were 50% (range 34% to 66%), 53% (range 36% to 70%), and 71% (range 54% to 83%), respectively. CPAM appeared to be far superior to these three methods with a utility of 94% (range 81% to 98%; p < 0.05). Patient and operator acceptability of CPAM was high. Skin pressure problems are a potential risk if the CPAM probe is left attached to the skin for more than 24 hours. CPAM was a valuable and reliable means of monitoring infrainguinal vascular reconstructions. Apart from being inexpensive, continuous, objective, and simple, CPAM is noninvasive and painless. It is advisable to remove the probe 24 hours after surgery, when the most crucial period for graft monitoring has passed.

Accuracy of lung imaging in metastases with implications for the role of thoracoscopy.

Thoracoscopy for wedge resection of lung metastases is rapidly increasing in frequency. This technique precludes bimanual palpation of the lung to locate additional lesions not seen on the surface. Finger palpation is inadequate. Implications regarding the failure to identify all metastases and the negative impact on long-term survival led us to review retrospectively the correlation between pathologic findings and imaging reports. One hundred forty-four patients who had resection of lung metastases from colorectal cancer were studied. All had chest roentgenograms and 72 had computed tomographic scans as well. Chest roentgenogram and computed tomographic reports differed in the number of nodules reported in 17 of 72 patients (24%). In 3 of 17 patients chest roentgenogram showed more nodules than computed tomography. Chest roentgenogram differed from pathologic findings at surgery in 57 of 144 patients (39%). Twenty-six of 57 patients (46%) had more lesions than chest roentgenogram detected and 31 had fewer. Computed tomographic scans differed from pathologic findings in 30 of 72 patients (42%). If one or two lesions were imaged, 12 patients had fewer cancers (some lesions were benign) and 18 had more cancers than computed tomography reported; computed tomographic scans erred 28% of the time. The inability to adequately palpate the entire lung using the thoracoscope alone markedly impairs the surgeon's ability to know if a resection of all lesions has been done. The validity of using thoracoscopy resection in the management of metastatic disease is seriously questioned other than for diagnosis.

Squamous metaplasia in hormonally treated prostatic cancer. Significance during follow-up.

A prospective study of 59 hormonally treated prostatic cancer cases was undertaken during follow-up with sequential transrectal palpation and fine-needle aspiration. At initiation of therapy patients' ages ranged from forty-eight to eighty-two years (median, 68 years). The usual follow-up interval was 6 +/- 3 months, and follow-up periods ranged from six months to one hundred twenty months (median 48 months). The cytologic findings were categorized under four cytologic response types and palpation findings under five response grades. Four different degrees of squamous metaplasia (1+, 2+, 3+, 4+) were observed in smears, depending on semiquantitative determination of squamous metaplastic cells in relation to the total amount of benign and malignant epithelial cells in the smear. There were 341 follow-up observations in which both transrectal fine-needle aspiration cytology and palpation were done. In 306 of these, cytologic findings were found to be adequate. Comparison of squamous metaplasia with cytologic response types revealed a highly significant difference between the benign state and recurrence/frank malignancy. This was also true when frequency of squamous metaplasia was compared with palpatory response grades. It was found that squamous metaplasia can be a valuable adjunct to other cytomorphologic changes such as shrinkage of tumor cell size and decrease in size of nucleoli or its disappearance, in determining response to hormonal therapy.

Blood pressure after cardiopulmonary bypass: which technique is accurate?

To evaluate the accuracy with which a patient's aortic blood pressure can be estimated upon separating from cardiopulmonary bypass (CPB), simultaneously recorded radial artery pressure, oscillometric brachial artery pressure, pressure in the CPB circuit, and the surgeon's estimate of blood pressure by aortic palpation were compared to directly measured aortic root pressure. After obtaining institutional approval and written informed consent, 20 patients requiring CPB for cardiac operations were studied. General anesthesia was induced and maintained with fentanyl, vecuronium, and enflurane. Blood pressure measurements were made before CPB and repeated 2, 5, and 10 minutes after discontinuation of CPB. Radial artery systolic pressure before CPB and radial artery mean pressure 10 minutes after CPB were different from the aortic root pressures (P < 0.05). Although the other radial artery pressures and the surgeon's estimate of systolic aortic pressure were statistically similar to the aortic root pressures, the range of differences was clinically significant. The oscillometric technique and CPB line were poor estimates of aortic root pressure. Of the techniques used to estimate aortic blood pressure, including radial arterial, oscillometric, aortic line of the CPB circuit, and digital palpation, the radial arterial was the best, and the aortic line from the CPB machine and palpation by the surgeon were the worst. When a clinician is unsure of the blood pressure during separation from CPB, direct measurement of central aortic blood pressure is advised.

Thoracoscopic localization techniques for patients with solitary pulmonary nodule and history of malignancy.

BACKGROUND: Our aim was to evaluate the best intrathoracoscopic localization technique in patients with single pulmonary nodule and a history of malignancy. METHODS: We divided 50 patients in two groups, well matched for diameter and depth of the pulmonary lesion. In 25 patients we performed intrathoracoscopic ultrasound to locate the pulmonary nodule (group A), whereas in the other 25 patients the radio-guided technique was adopted (group B). In both group A and group B, the localization techniques were compared with finger palpation. In group A, 12 nodules were in the left lung and 13 in the right one; in group B, 11 lesions were in the left and 14 in the right lung. In both groups, the distance of the nodule from the pleural surface was 2.6 +/- 0.5 cm (2 to 2.5 cm in 14 patients, and >2.5 cm for the remaining 11). The diameter of the nodule was 1.26 +/- 0.22 (< or =1 cm in 10 patients, and 1 to 1.5 cm in 15) in both groups. All patients underwent thoracoscopic wedge resection, and 10 patients with a primary pulmonary lesion underwent posterior-lateral thoracotomy for lobectomy and mediastinal lymphadenectomy. RESULTS: In group A, ultrasound localized the nodule in 24 of 25 patients (96%) whereas finger palpation localized it in 19 of 25 (76%; not significant). In group B, both the radio-guided and finger palpation techniques localized the nodule in 20 of 25 patients (80%; not significant). No complications were recorded with the ultrasound technique; however, 10 cases of pneumothorax were detected after the radio-guided technique (p < 0.01). CONCLUSIONS: Both the ultrasound and radio-guided techniques are accurate to detect solitary pulmonary nodules, but the radio-guided method yields complications as compared with the ultrasound.

Cutaneous two-point discrimination thresholds and palpatory sensibility in chiropractic students and field chiropractors.

OBJECTIVE: To investigate differences in cutaneous 2-point discrimination and palpatory sensibility at different stages in a chiropractic training course and in field chiropractic practitioners. METHODS: Static 2-point discrimination and palpation thresholds of the skin in the dominant index finger were measured in 102 subjects taken from the first and final years of a chiropractic degree/masters course and practicing field chiropractors. Two-point discrimination measurements were obtained by applying modified electronic engineering calipers mounted on a lever arm, which allowed the points to be lowered onto the skin at a constant rate and pressure. Palpation measurements were made by locating a nylon monofilament under a variable number of sheets of paper held in a purpose-designed frame. Paper thickness was measured by using electronic engineering calipers. Differences in the 2-point discrimination and palpation threshold measurements recorded between cohorts were analyzed by using 1-way analysis of variance (ANOVA) and Tukey-Kramer multiple comparison tests. RESULTS: A statistically significant reduction was observed in 2-point discrimination thresholds between first-year (control group) and fifth-year chiropractic students (P <.001) but not between the control group and the practicing field chiropractors. A progressive increase was observed in palpatory sensibility, as determined by the thickness of paper through which the nylon monofilament could be felt, from first-year chiropractic students to practicing field chiropractors. A significant difference in palpatory threshold was also found between first year students and chiropractors (P <.05). Although both 2-point discrimination and palpatory discrimination thresholds were different between groups, no statistically significant correlation could be made to link statically recorded 2-point discrimination acuity with palpatory sensibility. CONCLUSION: These investigations support previous research that 2-point discrimination improved through the chiropractic training program at the Anglo-European College of Chiropractic but that this appeared not to be retained into field practice. However, the changes in palpatory ability were maintained and improved on in professional practice, suggesting that 2-point discrimination thresholds do not provide a good measure of palpatory ability.

Effect of daily parathyroid hormone (1-34) on lumbar fusion in a rat model.

BACKGROUND CONTEXT: Despite numerous studies evaluating the anabolic effects of intermittent administration of parathyroid hormone (PTH) on bone, there are no published studies examining its effect on spinal fusion outcomes. PURPOSE: To determine the effect of daily injection of human recombinant PTH(1-34) on posterolateral lumbar fusions in a rat model. STUDY DESIGN: Prospective, case-controlled, preclinical animal study. OUTCOME MEASURES: Manual palpation and serum osteocalcin. METHODS: Single-level, intertransverse process spinal fusions were performed with iliac crest autograft in 56 Sprague-Dawley rats. Animals received daily injections of placebo or PTH(1-34). At 6 weeks, fusion masses were assessed by manual palpation. Serum osteocalcin levels were assessed in a subset of the animals. RESULTS: Manual palpation revealed the control group to have a fusion rate of 37% (10/27) and the PTH(1-34)-treated group to have a fusion rate of 52% (15/29). Mean serum osteocalcin levels were 59.8 and 88.6 ng/L for the control and PTH(1-34) groups, respectively. CONCLUSIONS: There was a trend towards greater fusion rate in the PTH(1-34) group as compared with the placebo group. Further, PTH(1-34) administration was associated with a significant increase in osteocalcin levels. Certainly, further investigations are warranted, as an injectable agent capable of increasing fusion rates would be of great clinical value.

Video-assisted approach for transxiphoid bilateral lung metastasectomy.

Radical resection has proved to be the most effective treatment of lung metastases, and manual palpation is considered the most accurate method for detection of occult metastases. To allow bilateral manual palpation during video-assisted metastasectomy, we developed a transxiphoid approach without sternotomy. Twenty-one lesions were successfully resected in 6 patients without mortality or morbidity. This approach allows easy manual palpation of the lungs and facilitates bilateral video-assisted metastasectomy.

The role of computed tomography in the investigation of recurrent axillary disease in patients with carcinoma of the breast.

Carcinoma of the breast commonly recurs in the axilla. A nodal mass may be palpable and computed tomography (CT) is frequently requested in order to differentiate recurrent tumour from the longer term effects of surgery and radiotherapy. We have reviewed the CT scans of 35 such patients referred consecutively to our CT unit. CT only detected the presence of recurrent tumour in one patient in whom a mass could not be palpated. This patient had a previously irradiated 'wooden' axilla making clinical examination impossible. CT failed to diagnose recurrence in two patients; one with disease in normal sized nodes and the other with axillary vein thrombosis. We conclude that CT of the axilla only appears to be of value when the axilla is impossible to palpate due to previous treatment. The key to the diagnosis of axillary tumour recurrence is careful palpation supplemented by aspiration cytology of any mass. When no mass is evident on clinical examination, CT is unlikely to demonstrate disease.

Pilot study of the heterogeneous patterns of masticatory muscle coordination in nonpatient population.

This pilot study characterized coordination patterns of the muscles of mastication during voluntary chewing in a nonclinical population. Dental students (n = 177) who did not exhibit symptoms of temporomandibular disorder were screened by a comprehensive muscle and temporomandibular joint palpation examination. A group of 44 students was identified on the basis of the presence of four or more tender points indicated during palpation. This group was further subgrouped by the absence (group A-1) and presence (group A-2) of temporomandibular joint clicking. Five volunteers from groups A-1 and A-2 and five volunteers without any palpation tenderness and joint clicking (control group) were examined by simultaneous recordings of electromyography of bilateral masseter and posterior one third of the temporalis muscles and by mandibular kinesiography. The electromyographic coordination pattern for the control group demonstrated predominantly working masseter muscle activity. This "predominant working masseter" pattern was not observed in groups A-1 or A-2. Additional analyses of the recordings indicated that a hypoactive tendency of the working side masseter muscle particularly outlasting the tooth contact was present in group A-1, whereas significant hyperactivity of the posterior one third of the temporalis was present in group A-2. The data suggested that an asymptomatic nonpatient population may be functionally diverse.

High resolution real-time ultrasonography in the localization of the undescended testis.

In a prospective study ultrasound was compared to palpation in 41 instances in which a testis was not present in the scrotum. A testis was palpable in 20 of these instances and not palpated in 21. Of 20 palpable undescended testes 14 (70 per cent) were identified by ultrasound. Of the 21 instances in which a testis was not palpated 3 intra-abdominal and 5 inguinal testes were identified at exploration. One of these organs (an inguinal testis) was identified by ultrasound. Two false positive sonograms in which a gubernacular structure mimicked an undescended testis occurred. Sonography cannot satisfactorily stand alone as a screening modality in the management of the undescended testis.
