Correlation of mechanical imaging and histopathology of radical prostatectomy specimens: a pilot study for detecting prostate cancer.

PURPOSE: A new modality termed mechanical imaging has recently been developed. We determined whether mechanical imaging could be used to detect prostate cancer in radical prostatectomy specimens. MATERIALS AND METHODS: Stress patterns on the surface of excised prostates were evaluated using the data obtained from a planar piezoelectric resistive force sensor array. Seven radical prostatectomy and 2 cystoprostatectomy specimens were manually palpated and evaluated by the mechanical imager. The prostates were histopathologically analyzed for the presence of cancer. The results of the manual palpation, mechanical imaging and pathological analysis were correlated. RESULTS: Mechanical imaging correlated closely with nodules palpated in all specimens and in 1 it revealed a suspicious area undetected by palpation, which on subsequent histological analysis demonstrated carcinoma. CONCLUSIONS: Mechanical imaging can detect areas of heterogeneity in prostate tissue which correlate with cancer. Our findings provide the basis for the development of a transrectal mechanical imaging probe for prostate cancer detection.

Perineural invasion and Gleason 7-10 tumors predict increased failure in prostate cancer patients with pretreatment PSA <10 ng/ml treated with conformal external beam radiation therapy.

PURPOSE: It has been well established that prostate cancer patients with pretreatment PSA <10 ng/ml enjoy excellent bNED control when treated with definitive external beam radiation therapy. This report identifies predictors of failure for patients with pretreatment PSA <10 ng/ml. These predictors are then used to define favorable and unfavorable prognostic subgroups of patients for which bNED control is compared. METHODS AND MATERIALS: Between 3/87 and 11/94, 266 patients with T1-T3NXM0 prostate cancer and pretreatment PSA values <10 ng/ml were treated with definitive external beam radiation therapy. Median central axis dose and median follow-up for the entire group was 72 Gy (63-79 Gy) and 48 months (2-120 months). Predictors of bNED control were evaluated univariately using Kaplan-Meier methodology and the log-rank test and multivariately using Cox proportional hazards modeling. Covariates considered were pretreatment PSA, palpation stage, Gleason score, presence of perineual invasion (PNI) and central axis dose. Independent predictors based on multivariate results were then used to stratify the patients into two prognostic groups for which bNED control was compared. bNED failure is defined as PSA > or = 1.5 ng/ml and rising on two consecutive determinations. RESULTS: Univariate analysis according to pretreatment and treatment factors for bNED control demonstrates a statistically significant improvement in 5-year bNED control for patients with Gleason score 2-6 vs. 7-10, patients without evidence of perineural invasion (PNI) vs. those with PNI, and patients with palpation stage T1/T2AB vs. T2C/T3. Multivariate analysis demonstrates that Gleason score (p = 0.0496), PNI (p = 0.0008) and palpation stage (p = 0.0153) are significant independent predictors of bNED control. Based on these factors, patients are stratified into a more favorable prognosis group (Gleason 2-6, no PNI, and stage T1/T2AB, n = 172) and a less favorable prognosis group (Gleason 7-10 or PNI or T2C/T3, n = 94). A comparison of the two groups reveals that bNED control is significantly lower in the less favorable prognosis group (74% vs. 91% at 5 years, p = 0.0024). CONCLUSIONS: (1) This report identifies Gleason 7-10 and the presence of PNI as well as palpation stage T2C/T3 as factors that predict worse bNED outcome for patients with pretreatment PSA <10 ng/ml who are treated with radiation therapy alone. (2) Patients with these pretreatment prognostic factors may benefit from adjuvant therapies or altered treatment programs. (3) In order to make fair comparisons between radiation therapy and prostatectomy series, the distribution of perineual invasion and Gleason 7-10 must be taken into account.

Noninvasive detection of inguinofemoral lymph node metastases in squamous cell cancer of the vulva by L-

In the majority of patients with early stage squamous cell cancer (SCC) of the vulva, an inguinofemoral lymphadenectomy is performed (in retrospect) for diagnostic reasons: exclusion of inguinofemoral lymph node metastases. The morbidity of this procedure, however, is significant. The aim of the present study was to evaluate noninvasive detection of inguinofemoral lymph node metastases by positron emission tomography (PET) using L-[1-11C]-tyrosine (TYR) as tracer. In patients with SCC of the vulva, scheduled for resection of the primary tumor and uni- or bilateral inguinofemoral lymphadenectomy, results of preoperative palpation of the groins and TYR-PET imaging were compared with histopathology. PET imaging was performed using two different methods. In a first group (n = 16), nonattenuation corrected 'whole body' scans were performed, and in a second group (n = 9), attenuation corrected static emission scans. Sensitivity, specificity, accuracy, and positive and negative predictive value for palpation were 62%, 89%, 82%, 67%, and 87% per groin. Sensitivity, specificity, accuracy, and positive and negative predictive value for TYR-PET were calculated for the two methodologies separately and overall. There were no significant differences. Overall values were 53%, 95%, 94%, 33%, and 98% per lymph node and 75%, 62%, 65%, 41% and 88% per groin. Detection of inguinofemoral lymph node metastases by TYR-PET is not superior to palpation. Neither palpation nor TYR-PET is able to adequately predict or exclude presence of inguinofemoral lymph node metastases in patients with SCC of the vulva.

Endofinger for tactile localization of pulmonary nodules during thoracoscopic resection.

To localize a deeply situated small pulmonary nodule during thoracoscopic resection, we developed as instrument a so-called "endofinger" for tactile localization of the nodule, and examined its usefulness. An attempt was made in 26 patients, using endofinger palpation under thoracoscopy, to localize twenty-six pulmonary nodules, each of which was less than 20 mm in diameter (mean 12.2 mm) and situated apart from the pleural surface. An endofinger comprises an extended "finger' section connected with a sleeve section. The sleeve section fits with a large contract area over the surgeon's forefinger, effectively lengthening it. The surgeon uses an endofinger in each hand and palpates a pulmonary nodule with the endofinger from two directions simultaneously. Surgeons could feel the hardness of nodules with a high degree of sensitivity. The sense of touch of the endofinger is much better than that of a simple bar, due to the large contact area of the sleeve section with the real finger. With the endofinger palpation 22 of 26 nodules were localized and their margins confirmed. All of 19 nodules larger than 10 mm in size had their locality confirmed by endofinger palpation. Four of 7 nodules smaller than 10 mm in size could not be localized, however. The endofinger is a useful instrument for tactile localization of pulmonary nodules under thoracoscopic surgery, especially for nodules larger than 10 mm. The method is simple, low-cost, time-saving, and has no complications.

[The diagnostic value of rectal ultrasound in the assessment of parametrial infiltration of cervix cancer].

In addition to rectal palpation, rectosonography seems to be a promising method in pretherapeutic examination of the parametrium in patients with cervical carcinoma. To evaluate the usefulness of this examination we determined the sensitivity and specificity of rectal palpation performed by one examinator, rectal palpation performed by changing examiners, and rectal sonography. The results of the clinical examination of 128 parametria (64 women) were compared to histological findings following Wertheim-Meigs operation. Sensitivity and specificity were as follows one examiner 48% and 96%, changing examiners 44% and 94%, rectosonography 55% and 99%. In conclusion, we suggest that rectal sonography is a careful and moderate method that can be an important supplement to rectal palpation in pretherapeutic staging of cervical cancer.

Salivary gland disease in human immunodeficiency virus-positive women from the WIHS study. Women's Interagency HIV Study.

OBJECTIVE: To determine the prevalence of enlargement, tenderness, and absence of saliva on palpation as indicators of salivary gland disease in women who are human immunodeficiency virus (HIV)-positive. STUDY DESIGN: The study subjects are participants in the Women's Interagency HIV Study (WIHS), a multicenter study examining HIV-seropositive women and at-risk HIV-seronegative women. A total of 576 HIV-positive women and 152 HIV-negative women were examined at their baseline oral visit for clinical markers of salivary gland disease. Viral load levels, CD4 counts, and CD8 counts were obtained as part of the related core study. RESULTS: HIV-positive women had higher rates of salivary gland enlargement (4.3%), tenderness (6.9%), and absence of saliva on palpation (26.6%) compared with HIV-negative women, who had rates of 1.3%, 4.6%, and 13.2%, respectively. Absence of saliva was significantly different (P =. 001) between the 2 groups. When 2 of the 3 clinical findings were combined, comparisons between the HIV-positive women and HIV-negative women became significant at the P <.05 level for every combination, except for enlargement/tenderness for the submandibular/sublingual gland. For the HIV-positive women, the viral load was significantly related to enlargement (P =.019) and enlargement/absence of saliva on palpation (P =.037) for the parotids and enlargement (P =.046), absence of saliva (P =.043), and enlargement/absence of saliva (P =.022) for the submandibular/sublingual glands. Significant linear trends were found for increasing viral load and enlargement (P =.013) and enlargement/tenderness (P =.024) for the submandibular/sublingual glands. Significance was present for submandibular/sublingual absence of saliva and tenderness/absence of saliva for CD4 and CD8 medians. CONCLUSIONS: Serostatus is related to salivary gland disease as assessed by glandular enlargement, tenderness, and absence of saliva on palpation. Furthermore, our findings indicate that a multidimensional approach to gland assessment may provide a more complete and perhaps more adequate description of glandular involvement with HIV infection.

Thoracoscopic localization techniques for patients with a single pulmonary nodule and positive oncological anamnesis: a prospective study.

INTRODUCTION: Our aim was to evaluate the best intrathoracoscopic localization technique in patients with a single pulmonary nodule and a history of malignancy. METHOD: We divided 30 patients into two groups, well matched for diameter and depth of the pulmonary lesion. In 15 patients (group A) we performed intrathoracoscopic ultrasound (US) to locate the pulmonary nodule, while in the other 15 patients (group B) intrathoracoscopic radioguided occult lesion localization (ROLL) was used. In both groups, the localization technique was compared to finger palpation. In group A, 6 nodules were in the left lung and 9 in the right; in group B, 7 lesions were in the left and 8 in the right lung. In each group, the distance of the nodule from the pleural surface was 2-2.5 cm in 8 patients, and > 2.5 cm in the remaining 7. In both groups, the diameter of the nodule was </= 1 cm in 6 patients, and 1-1.5 cm in 9 patients. All patients underwent thoracoscopic wedge resection, and 6 patients with a primary pulmonary lesion underwent posterior-lateral thoracotomy for lobectomy and mediastinal lymphadenectomy. RESULTS: In group A, US localized the nodule in 15 of 15 patients (100%) while finger palpation located the nodule in 11 of 15 (73%) (P = NS). In group B, both ROLL and finger palpation localized the nodule in 12 of 15 patients (80%) (P = NS). CONCLUSION: Intrathoracoscopic US seems superior to radioguided and finger palpation localization techniques for single pulmonary nodules. Thus, we are now routinely using intraoperative US to identify single pulmonary nodules.

Low-power laser treatment for shoulder pain.

OBJECTIVE: The objective of this study is to investigate the effect of low-power gallium-arsenide laser treatment on the patients with shoulder pain. BACKGROUND DATA: Low-energy laser therapy has recently been popularized in the treatment of various rheumatologic, neurologic, and musculoskeletal disorders such as osteoarthritis, rheumatoid arthritis, fibromyalgia, carpal tunnel syndrome, rotator cuff tendinitis, and chronic back pain syndromes. METHODS: A total of 40 patients who applied to our clinic with shoulder pain and complied with the selection criteria were included in the study. The patients were randomly assigned into Group I (n = 20, laser treatment) and Group II (n = 20, control). In Group I, patients were given laser treatment and an exercise protocol for 10 sessions during a period of 2 weeks. Laser was applied over tuberculum majus and minus, bicipital groove, and anterior and posterior faces of the capsule, regardless of the existence of sensitivity, for 1 min at each location at each session with a frequency of 2000 Hz using a GaAs diode laser instrument (Roland Serie Elettronica Pagani, wavelength 904 nm, frequency range of 5-7000 Hz, and maximum peak power of 27 W, 50 W, or 27 x 4 W). In Group II, placebo laser and the same exercise protocol was given for the same period. Patients were evaluated according to the parameters of pain, palpation sensitivity, algometric sensitivity, and shoulder joint range of motion before and after treatment. RESULTS: Analysis of measurement results within each group showed a significant posttreatment improvement for some active and passive movements in both groups, and also for algometric sensitivity in Group I (p < 0.05-0.01). Posttreatment palpation sensitivity values showed improvement in 17 patients (85%) for Group I and six patients (30%) for Group II. Comparison between two groups showed superior results (p < 0.01 and p < 0.001) in Group I for the parameters of passive extension and palpation sensitivity but no significant difference for other parameters. CONCLUSIONS: The results of our study have shown better results in palpation sensitivity and passive extension, but no significant improvement in pain, active range, and algometric sensitivity in laser treatment group compared to the control group in the patients with shoulder pain.

The effect of structured training on breast self-examination search behaviors as measured using biomedical instrumentation.

BACKGROUND: Although breast self-examination (BSE) has long been recommended by health care practitioners as a complement to mammography and clinical breast examination, only a small percentage of U.S. women report doing monthly BSE, and an even smaller number of women perform this procedure proficiently. OBJECTIVES: To measure the effect of a structured training protocol on improving two dimensions of BSE technique (depth of palpation and search time) in each of two search patterns (vertical strip and concentric circle) using biomedical instrumentation. METHODS: For this study, 41 young women participated in a structured training protocol for BSE instruction. The dependent variable was thoroughness of search, for which there were two measures: depth of palpation (displacement of the sensors) and duration of the examination. An instrumented breast model designed by the investigator provided quantitative measurements of examination behaviors and was used to test outcomes of the instruction. RESULTS: Multivariate analyses demonstrated an overall difference across examinations (F = 28.03; p = 0.0001). Univariate tests showed treatment effects for both dependent variables: depth of palpation and duration of examination. CONCLUSIONS: Individual training in BSE with guided practice improved two measures of thoroughness of search: depth of palpation and duration of search time. Biomedical instrumentation represented a novel approach to the collection of quantitative performance data.

Stimulus-evoked EMG monitoring during transpedicular lumbosacral spine instrumentation. Initial clinical results.

OBJECTIVES: The authors developed and evaluated an electrophysiologic method for minimizing the risk of nerve root trauma associated with the placement of pedicle screws during transpedicular lumbosacral fixation in humans. SUMMARY OF BACKGROUND DATA: Various methods have been evaluated to reduce the high complication rates associated with lumbosacral transpedicular fixation, but none are without significant limitations or drawbacks. Using a pig model, we previously developed a technique for assessing, by electrophysiologic means, the potential risk associated with placement of a screw at a given site. In this report, the authors describe their experience with this technique in patients. METHODS: Electromyogram (EMG) was monitored from eight lower extremity muscles bilaterally. Square-wave electrical shocks (200 microseconds, 7 mA) were delivered through the instruments used to form and evaluate each pedicle hole, and through the screw itself if placement was deemed safe. Provided that the instruments used (e.g., awl, tap, probe) do not exit from bone in any direction below the entry point, the resistance of bone to the 7 mA stimulus intensity is high enough such that no nerve roots are stimulated, and the EMG traces remain flat. Conversely if EMG is evoked, it warns of a potential perforation in a pedicle wall or in the anterior body. RESULTS: The authors evaluated this technique in 18 patients in whom a total of 102 screws were placed. Based on results of electrophysiologic and palpatory evaluation, 68% of the screws were placed in a satisfactory manner. Electrophysiologic evidence of a perforation, which could not be confirmed by palpation or visualization, was seen in another 13% of this total. The remaining 19% of screw placements involved sites where a defect was missed originally by palpation alone, but was located based on electrophysiological testing combined with palpation and visualization (11%), and where a perforation was initially palpated (8%). There was no postoperative morbidity associated with malpositioned screws. CONCLUSIONS: Our results indicate that the technique is sensitive and, based on early clinical results, reliable in the detection of perforations in pedicle screw placement. Moreover, the method is inexpensive, rapid, and easily implemented into a standard intraoperative monitoring protocol.

Functional disturbances of the masticatory system related to temporomandibular joint involvement by rheumatoid arthritis.

Several theories have been proposed concerning the aetiology of dysfunction of the temporomandibular joint (TMJ). To analyse the relationship of radiographic changes to clinical signs and symptoms of TMJ dysfunction, the present study was conducted in subjects highly predisposed to TMJ involvement, i.e. in patients with rheumatoid arthritis (RA). The aim of the study was to estimate the frequency of disturbances in the masticatory system of RA patients. In addition, the relationship between TMJ abnormalities and the signs and symptoms of dysfunction was investigated. The study consisted of sixty patients with RA and forty control subjects. Asymptomatic subjects were more frequent in the RA group than in the controls. Muscle pain during palpation was recorded in 53.3%, clicking in 53.3%, crepitation in 21.7%, reduced movement capacity of the TMJ in 41.7%, and restricted mouth opening in 31.7% of the RA patients examined. In the control group the most common symptoms and signs were clicking (57.5%), muscle pain during palpation (57.5%) and restricted opening (25.0%). Normal radiographic appearance of the TMJ in RA patients was found in 31.7%. Minor changes comprised 31.7%, moderate changes 21.6%, and severe changes or total loss of the condyle 15.0%. In the control group a normal joint was detected in 87.5%, while minor changes were encountered in 7.5%, and moderate or severe changes only in 5.0%. No relationship was found between Helkimo's anamnestic, clinical or occlusal indices and the severity of the disease graded according the criteria outlined by the American Rheumatism association (ARA). In the ARA group the frequency of signs and symptoms of dysfunction increased with the destructive changes in the TMJ area. In the controls, muscle pain during palpation and clicking sounds in the TMJ were most commonly connected with normal radiographic appearance of the TMJ. In the discriminant analysis the most discriminating factors were crepitation, tenderness to palpation of muscles and movement of TMJ.

The kinematic center: a reference for condylar movements.

The kinematic center of the temporomandibular condyle is that condylar point which follows as much as possible the same movement path during different types of mandibular movements. In this study, the location of the kinematic center with respect to the palpated lateral pole of the condyle was investigated. Also, the lengths of the condylar movement path reconstructed by means of the kinematic center and the palpated condyle were compared. Mandibular movements were recorded with 6 degrees of freedom in 20 healthy subjects. A software procedure calculated the location of the kinematic center as that mandibular point for which the protrusive and opening movement path showed a minimal difference. For each subject, its average location was calculated on the basis of 16 pairs of protrusive and opening movements. The kinematic center was located posteriorly and superiorly with respect to the palpated condylar point (p < 0.0001). The standard deviation in the anterior-posterior coordinate of the average kinematic center was smaller than that in the superior-inferior coordinate (p < 0.0001). During opening, the path length of the kinematic center is longer than that of the palpated lateral pole of the condyle (p < 0.0001). In contrast to left-right differences found in the path lengths of the lateral pole of the condyle, no left-right differences were found for the kinematic center.

Validity of clinical measures of shoulder subluxation in adults with poststroke hemiplegia.

OBJECTIVES: Shoulder subluxation after cerebrovascular accident has been associated with chronic pain, orthopedic complications, peripheral nerve damage, and autonomic dysfunction. Clinical diagnosis and gradation of subluxation is problematic due to the lack of precision in frequently used measures. The objective of this study was to assess the validity of clinical techniques used to assess inferior subluxation of the hemiplegic shoulder by comparing these techniques with radiographic measurement. METHOD: In 20 male subjects with hemiplegia, the presence, type, and degree of subluxation was assessed with three clinical measures: palpation, arm length discrepancy, and thermoplastic jig measurement. Anterior-posterior X rays of the hemiplegic shoulder were taken after clinical examination. RESULTS: Spearman rank correlation coefficients between the X rays and the three clinical measures were relatively low. Palpation had the highest correlation (rs = .76), followed by arm length discrepancy (rs = .46), and thermoplastic jig measurement (rs = .42). CONCLUSION: These findings provide cautious optimism about using these clinical measures to identify subluxation. Although detection was best with palpation, the likely inability to determine clinical overcorrecting of subluxation makes use of palpation alone suspect. Improved techniques of arm length measurement may provide a solution to this problem. These findings further necessitate that improved procedures for clinical assessment of subluxation be developed.

Intraoperative ultrasonography of the liver in patients with abdominal tumors: a new approach.

OBJECTIVES: To compare liver intraoperative ultrasonography (IOU), computed tomography (CT), preoperative ultrasonography (USG), and intraoperative inspection and palpation in the detection of hepatic lesions in patients with abdominal tumors. METHODS: This was a prospective study including 60 patients with abdominal tumors evaluated by USG, CT, inspection and palpation, and hepatic IOU during exploratory laparotomy. Sensitivity, specificity, and positive and negative predictive values for all methods were calculated. Agreement of methods with histopathologic results was calculated by kappa statistics and the Spearman coefficient. RESULTS: Of the 60 patients, 49 (81.6%) had positive findings for hepatic lesions. Lesions could not be counted in 3 patients. The 46 remaining cases were diagnosed by histologic examination. Sensitivity, specificity, and positive and negative predictive values were 42.9%, 88.9%, 90%, and 40% for USG; 59.5%, 77.8%, 86.2%, and 45.2% for CT; 69.0%, 88.9%, 93.5%, and 55.2% for inspection and palpation; and 90.5%, 77.8%, 90.5%, and 77.8% for IOU, with histologic examination used as a criterion standard. Fair to moderate agreement was found for USG, CT, and inspection and palpation (kappa = 0.24, 0.31, and 0.49, respectively). Substantial agreement was found for IOU (kappa = 0.68). Changes in surgical strategy were made in 19 (41.3%) of the 46 cases with positive findings. CONCLUSIONS: High sensitivity associated with substantial agreement with histopathologic findings shows that IOU is an indispensable evaluation method for hepatic screening in patients with abdominal tumors who undergo laparotomy and should become a routine procedure wherever available.

Clinical presentation of pyloric stenosis: the change is in our hands.

BACKGROUND: Hypertrophic pyloric stenosis classically presents as projectile vomiting during the third to fourth week of life, associated with good appetite. Additional classical presenting findings include palpation of the pyloric tumor, described as olive-shaped; a visible gastric peristaltic wave after feeding; and hypochloremic, hypokalemic metabolic alkalosis. It was recently claimed that this presentation has changed due to the easier access to gastrointestinal imaging. OBJECTIVE: To validate this contention and discuss possible reasons. METHODS: We conducted a retrospective chart review of all patients who underwent pyloromyotomy for HPS between 1990 and 2000. Only patients with confirmed HPS at the time of surgery were included. We also performed a comprehensive review of older studies for comparison. RESULTS: Seventy patients underwent pyloromyotomy over the 10 year period. Overall, 81% of patients were male infants and the mean age at diagnosis was 40 days. The mean duration of symptoms was 8 days. A firstborn child was noted in 43% of the cases. The classical symptom of projectile vomiting was absent in one-third of the patients, a pyloric tumor was not palpated in one-half of the cases, bicarbonate was higher than 28 mEq/L in 20%, and a pH of above 7.45 was present in 25% of patients. Hypochloremia was noted in about one-third. We found a good correlation between ultrasonographic width and length of the pylorus and the intraoperative findings. Pylorus length +/- 24 mm correlated with significantly longer duration of symptoms. When compared with previous studies, the main findings were not significantly different; namely, mean age at diagnosis, percentage of male gender, and duration to diagnosis. The decrease in the number of pyloric tumors palpated paralleled the increase in the use of upper gastrointestinal series and ultrasonography in particular. CONCLUSIONS: The clinical presentation of HPS has not actually changed despite the easier accessibility of GI imaging studies. However, the one significant change is the low percentage of pyloric tumors palpated, probably due to declining clinical skills accompanied by earlier utilization of imaging studies. The use of imaging and laboratory studies did not change the age at diagnosis but may have shortened the time for diagnosis and reduced the postoperative stay. Imaging and laboratory studies may be helpful for the subgroup with a non-classical clinical presentation.

[Torsion of appendix of testis and epididymis: a report of 4 cases].

We report our clinical and pathological observations on four patients with torsion of appendix testis or epididymis, and reviewed 72 cases of torsion of the appendages of intrascrotal organs collected from the Japanese literature; 35 cases of torsion of appendix testis, 36 cases of torsion of appendix epididymis and 1 case of torsion of paradidymis . Case 1 was a 10-year-old boy visiting us because of pain and swelling in his right scrotum continuing for the past ten days. His right scrotum was found to contain a hen-egg sized tender mass. The testis and epididymis could not be differentiated by palpation. The blood count disclosed 10,000 white blood cells. At operation, two appendix epididymis were found in his right scrotum. One of them was twisted 360 degrees clockwise and 10 x 8 x 5 mm in size. Case 2 was a 11-year-old boy with complaint of pain in his left lower abdomen and left scrotum for the past three days. Palpation of his left scrotal contents revealed a slightly hard testis and tender epididymis. At operation, we found his left spermatic cord to be twisted 90 degrees counterclockwise and appendix epididymis 180 degrees counterclockwise. The twisted appendix epididymis was 10 x 8 x 7 mm in size. Case 3 was a 13-year-old boy whose complaint was left scrotal pain. The upper pole of his left testis was found to be swollen and tender by palpation. The exposure of his left scrotum at operation revealed that his left epididymis was abnormally attached to his left testis and had two appendices. One of these appendix epididymis was twisted 180 degrees clockwise and measured 10 x 10 x 8 mm. Case 4 was a 19-year-old male who suffered from right testicular pain for the past seven days. He had a history of three intermittent episodes of similar right testicular pain during the past two years. His right testis was enlarged and palpated slightly hard and tender. We explored his right scrotum surgically and found the appendix testis twisted and enlarged to little-finger's head size. However, it was impossible to determine whether the rotation was clockwise or counterclockwise because the twisted appendix was too severely damaged. The preoperative diagnosis was correct in one case and three were erroneously diagnosed as having torsion of spermatic cord. All four cases were treated by surgery which relieved all patients of discomfort.

Relationships between risk factors and treatment outcome in a group of patients with temporomandibular disorders.

The aim of this study was to compare somatic complaints, anxiety, and pain related to temporomandibular disorders (TMD) in a group of TMD patients who had high scores for headache and muscle palpation compared with that of a group of TMD patients who had low or medium scores for headache and palpation before and 2 years after conservative TMD treatment, consisting of counseling, muscle exercises, and a stabilization splint. The high-score group consisted of 23 patients who had headaches several times a week or daily and had more than three muscles graded as severely tender to palpation. The low/medium-score group comprised 28 patients who had headaches hardly ever, once or twice a month, or several times a month, and with muscles graded as slightly or medium tender to palpation. The patients answered three questionnaires (McGill Pain Questionnaire [Norwegian version], a somatic complaints questionnaire, and the trait part of Spielberger Stait-Trait Anxiety Inventory) before and 2 years after treatment. The findings showed differences between the two groups concerning pain description, general muscle complaints, and anxiety both before and after the treatment, with the high-score group showing the highest values. In general, the treatment outcome had improved in the low/medium-score group but remained unchanged in the high-score group.

Evaluation of the general practice program of women education for breast self-examination.

The aim of the study was to evaluate the program of education of women for breast self-examination (BSE) in general practice. A random sample of 5% of women over 18 years of age, living in Dugave (a suburb in Novi Zagreb) were chosen for the study. The study covered 251 women of whom 122 (48.6%) presented for BSE training. Women were taught about BSE by the method which included the theoretical part, group discussion, practical training on silicon breast model, individual practice of BSE, and additional individual assessment of the acquired skill of BSE. Six months after the BSE training, out of 116 women presented for retesting, BSE was performed by 91 (78.4%) women: 75 (82.4%) performed BSE regularly once a month or in two months, while 60 (65.9%) women dedicated sufficient time to BSE. Assessment of BSE performance in our subjects showed palpation with the longer parts of fingers and palpation of the whole breast to be skills best mastered by the women. Palpation of the nipple area and palpation of the armpit were sections of BSE in which the women also achieved good results. It is surprising that breast inspection, easy as the procedure may seem, is the section of BSE in which the women did not achieve expected results. On the post-course assessment, as many as 15 (12.9%) women left out breast inspection, while 10 (8.6%) women performed breast inspection in a completely wrong way. Keeping self-records on BSE was by far the most poorly assessed part. Incomplete keeping of self-records on BSE findings is an important objection to BSE as a procedure which should contribute to the systematic continuous drive for early detection of breast cancer. The most important conditions for the education of women for BSE are the knowledge, ability and willingness of the GP and members of his team to provide health education to the population under their care. BSE is not the ultimate solution, but is a significant step in the continuous struggle against breast cancer. That is why it is essential that all women be informed about BSE and as many women as possible be covered by systematic education for BSE. Authors' results indicate that it is possible to implement the proposed model of continuous education of women for BSE within the scope of work of the GP's team.
