Paget-von Schroetter syndrome: case description in the light of the literature

A 27 year old patient with a thrombosis of the subclavian vein (Paget- von Schroetter's-syndrome) was treated successfully with a systemic streptokinase thrombolysis. Indications and success of the different therapeutic ways in current literature (conventional management, systemic and local thrombolysis) are compared to each other. The authors prefer treatment with systemic thrombolysis, patients with contraindications should be treated with conservative management. Nevertheless no final conclusions can be drawn, as there are no controlled studies comparing the different concepts in treatment.     

Image-directed percutaneous biopsies with a biopsy gun

Core tissue for histologic study is believed by many pathologists to be more diagnostic than material from needle aspiration. Recently, a biopsy "gun" has been introduced, which simplifies core biopsies. With this device, 182 biopsies of multiple anatomic sites were performed with ultrasonic, computed tomographic, and fluoroscopic guidance and 18-gauge needles. High-quality histopathologic specimens were obtained in 177 of the biopsies, and diagnostic target tissue was obtained in 167. Only three significant complications occurred: one bleeding complication that required transfusion and two cases of pneumothorax that necessitated placement of chest tubes. The biopsy gun eliminated the disjointed movements of conventional "skinny" needle biopsies, and none of the samples demonstrated significant "crush" artifact or obscuring blood, problems that are commonly associated with manual biopsy techniques. Patient discomfort was decreased with this system compared with that of manual biopsies, and the total procedure time was reduced. Because of these distinct advantages, the authors now use the biopsy gun exclusively for all percutaneous biopsies and recommend that other institutions consider the use of this biopsy method.     

Validating signals of ovulation: Do women who think they know,really know?

This study was carried out to test whether women who think they know when they ovulate, really know. Fifty-three women of age 18.7 to 46.1 (mean age 28.4 years) participated in initial interviews about ovulation. Criteria for recruitment included perceived ovulation, regular menstrual cycles, and not using hormonal contraception. Women collected and refrigerated urine samples from day 5 until they thought they ovulated. Samples collected within 48 h of the perceived signal were then tested for a pre-ovulatory LH surge. Of the 53 original participants, 36 women provided urine samples for 1-6 cycles, so that 87 cycles were tested. Subjective signals of ovulation varied between women and between cycles but included abdominal pain and changes in cervical discharge, libido, and mood. Of the 87 cycles tested, during which women identified one or multiple signals of ovulation, 37 of the 87 urine specimens tested positive for an LH surge for a concordance rate of 42.5%. Using the first tested cycle from the 36 women who provided urine specimens, 13 of those specimens demonstrated an LH surge, for a concordance rate of 36.1%. That rate dropped to 28% (7/25) when women who used basal body temperature as an ovulatory signal were excluded. Finally, the mean level of accuracy among the 15 women who contributed 3-6 urine specimens for testing was 48.9%. The results of this study demonstrate a low degree of concordance between LH surge and perceived ovulation among women who think they know when they ovulate. The most motivated study participants were right about half of the time. Although there is variation among women in their ability to know when they ovulate, this study suggests that, for most women, ovulation is concealed.     

Age and symptom experience at menopause in the Selska Valley, Slovenia

OBJECTIVE: To assess age and symptom experience at menopause in a high-altitude population in the Selska Valley of Slovenia. DESIGN: In four mountain villages, all houses were approached and 80% of eligible residents were interviewed. Additional women were interviewed for comparison in the valley below. Age at interview ranged from 32.7 to 85.5 years, with a mean of 58.2 years. The majority of women (62%) were aged 40 to 65 years. RESULTS: Of the 58 women interviewed, 7 had undergone menopause by hysterectomy (12%). Recalled age at natural menopause ranged from 42 to 54, with a mean of 50.3 (SD 2.9). By probit analysis, median age at natural menopause was 52.03. Fifty-five percent of participants reported ever having experienced a hot flash, although only 24% reported hot flashes during the 2 weeks before being interviewed. When the sample was limited to women aged 40 to 65, frequency of hot flashes in the 2 weeks before the interview was 39%. For all participants, the most frequent complaint was lack of energy (66%), followed by backaches (59%), and joint stiffness (53%). CONCLUSIONS: In contrast to expectations, age at menopause was not earlier and hot flash frequency was not significantly lower at higher elevations.     

Osteosarcomatosis

A review of the 690 cases of osteosarcoma in the radiographic file of the Armed Forces Institute of Pathology revealed 29 cases of "osteosarcomatosis" (multiple skeletal sites of osteosarcoma). Fifteen of these patients were 18 years old and under and manifested rapidly appearing, usually symmetric, sclerotic metaphyseal lesions. The remaining 14 patients were more than 18 years old and had fewer, asymmetric sclerotic lesions. In most patients (28 of 29), a radiographically dominant skeletal tumor was seen. Pulmonary metastases occurred in the majority of patients and were detected at the same time as the bone lesions. These 29 patients were studied with regard to demographic data and skeletal distribution and radiographic appearance of their lesions. As a result of the findings, a metastatic origin from a primary dominant osteosarcoma is favored over a multifocal origin as the basis for osteosarcomatosis. Osteosarcomatosis is more commonly encountered in the mature skeleton than has been previously recognized.     

ROLE OF EPIDURAL MEDICATION IN LUMBOSCIATIC SYNDROME

Role of epidural medication through caudal route was studied in 109 patients having lumbago with or without sciatica to highlight the value of this mode of treatment which relieved symptoms in more than 70% of cases without hospitalisation and without being off work for long periods as in usual methods of conservative treatment.KEY WORDS: Epidural medication, Backache, Lumbago, Sciatica     

The effect of bipolar electrosurgical coagulation waveform on a rat uterine model of fallopian tube sterilization

Laparoscopic bipolar electrosurgical sterilization has been employed for nearly two decades. This bipolar procedure was intended to reduce the incidence of unintended complications, such as bowel burns. However, compared to the monopolar procedure, it produced a higher failure rate. This study examines the role of the low power-high voltage coagulation waveform on the effectiveness of electrosurgical desiccation on the rat uterine model of the fallopian tube. Desiccations were performed with both Kleppinger and Storz forceps using generator settings from 2 to 6. Desiccations performed to the visual endpoint (blanch, swell, and collapse) required from 23.8 to 30.0 joules, although procedures performed at a generator setting of 2 required long application times, an average 15.4 sec (Storz) and 28.2 (Kleppinger). All bipolar procedures led to a loss of tissue at the desiccation site at 12 weeks postsurgery. Therefore, the electrosurgical coagulation waveform proved to be effective in producing adequate in vivo tissue destruction even at very low generator settings.
