Randomized trial of Codetron for pain control in osteoarthritis of the hip/knee

Patients suffering from pain due to osteoarthritis of the hip and knee participated in a double-blind placebo controlled trial using daily Codetron home care units for 6 weeks over the tibial, saphenous, popliteal and sciatic nerves, and tender points. Seventy-four percent of patients in the real Codetron (Group A) and 28% of the patients in sham Codetron (Group B) improved their pain level more than 25% as measured by visual analogue scale. The difference in pain improvement in the two groups was statistically significant (p less than 0.02 using Fisher's exact probability ratio). Other functional parameters proved to be insensitive to change in this study. This is highly suggestive of beneficial effect of nonhabituating Codetron as a complementary modality in the therapy of chronic pain conditions such as osteoarthritis.     

The Victim Care Service: a program for victims of sexual assault

Sexual victimization is a singularly traumatic event. At times, however, the implicit danger of the trauma experience itself gets exaggerated. For the victim the more lasting damage frequently stems from how he or she was treated by friends, family, health care providers, and public authorities following the incident. Treating the victimized patient as quickly and sensitively as possible is essential to minimizing the potential for further victimization. The Emergency Department at Boston City Hospital is frequently the site for the acute management of sexual assault victims. The Victim Care Service is designed to prevent secondary traumatization of such victims. The five-phase program and the fundamental assumptions upon which the phases are based are presented.     

Primary arteriovenous fistula between common iliac vessels: ultrasound, computer tomographic, and angiographic findings--a case report

A giant aneurysm of the right common iliac artery presenting with an arteriovenous fistula (AVF) between the iliac artery and iliac vein and deep venous thrombosis of the right lower extremity is reported. The clinical signs and the radiologic and surgical management of the condition are discussed. In addition a brief review of the literature is given.     

Chronic thromboembolic occlusion in the adult can mimic pulmonary artery agenesis

In the first 100 patients operated on for C T-E PH, three were referred with the diagnosis of UPAA having been made elsewhere. We found that many features of these two conditions are so similar that differential diagnosis is very difficult. Shared features may include findings on chest x-ray film, pulmonary angiography, CT scan and MRI studies. Since the two conditions vary substantially with respect to the methods of potential surgical correction, recognition of this possible differential diagnostic dilemma is important.     

Is a paediatrician required at caesarean section?

In a series of 460 consecutive deliveries there were 55 caesarean sections (mainly under epidural anaesthesia) without evidence of fetal distress and with a cephalic presentation. There was no statistically significant difference in the frequency of resuscitation in this group compared with 296 spontaneous vertex deliveries. It is concluded that a paediatrician is not routinely required at caesarean section under epidural provided there is no fetal distress and the presentation is cephalic.     

A randomized multicenter study to determine the efficacy of activity restriction for preterm labor management in patients testing negative for fetal fibronectin.

OBJECTIVE: To assess the impact of activity restriction (AR) on the incidence of preterm birth in women treated for preterm labor testing negative for fetal fibronectin (fFN). STUDY DESIGN: Women who were diagnosed with preterm labor and tocolyzed with magnesium sulfate were concurrently screened with fFN for the purpose of subsequent management. Included were consenting patients with negative fFN, gestational age 23 0/7-33 6/7 weeks, cervical dilation < or =3 cm, and minimal vaginal bleeding. Patients were randomized to AR or no AR. Primary study outcome was incidence of preterm delivery and interval from randomization to delivery. RESULTS: A total of 73 women with negative fFN were randomized (36 with AR, 37 without AR). The overall preterm birth rate was 40%, with 44.4% of patients with AR and 35.1% of patients without AR delivering preterm, p=0.478. CONCLUSION: Maternal AR did not impact pregnancy outcome. The incidence of preterm birth in symptomatic women testing fFN negative was higher than previously reported.     

Relationship of MAO-A promoter (u-VNTR) and COMT (V158M) gene polymorphisms to CSF monoamine metabolites levels in a psychiatric sample of caucasians: A preliminary report.

Monoamine oxidase A gene promoter (MAOA-uVNTR) and catechol-O-methyltransferase V158M (COMT-V158M) gene functional polymorphisms are reported to be associated with impulsive-aggression, but a biological intermediate effect remains to be determined. This study assessed the association of these polymorphisms with cerebrospinal fluid (CSF) monoamine metabolites as endophenotypes. Ninety-eight Caucasian psychiatric subjects were assessed for Axis I and II diagnosis. Subjects were genotyped for the functional polymorphisms, MAOA-uVNTR and COMT-V158M. CSF was obtained by lumbar puncture. Relationships of the two polymorphism to monoamine metabolites: HVA, 5-HIAA, and MHPG were examined. The higher-expressing MAOA-uVNTR genotype was associated with higher CSF-HVA levels in males only (n = 46) (195.80 pmol/ml, SD = 61.64 vs. 161.13, SD = 50.23, respectively; P = 0.042). No association was found with diagnosis. COMT-V158M had no association with CSF monoamine metabolites. The association of MAOA-uVNTR with dopaminergic activity in males is a preliminary finding that needs to be replicated in a larger sample of Caucasian males and relationships sought with clinical phenotypes.

Rapidly growing breast cancer: results of a retrospective analysis with a study of prognostic factors

Between January 1977 and December 1982, 66 consecutive patients have been treated for unilateral, rapidly progressing, non metastatic breast cancer. They were divided into three groups: Group A (n = 10): tumor whom volume had increased during the 2 months before diagnosis; Group B (n = 30): inflammatory signs (erythema, skin oedema, elevated local temperature) involving less than one half of the breast; Group C (n = 26): inflammatory signs involving more than one half of the breast. All patients where managed similarly: 3 to 4 courses of chemotherapy (CMF: n = 24; AVCF: n = 42), then loco regional irradiation therapy with cobalt 60, followed by maintenance chemotherapy, only if the first chemotherapy had proved effective (CMF: n = 13; AVCF: n = 27). Nine patients with residual tumor after radiotherapy underwent mastectomy with axillary dissection. The actuarial 5 years survival for the whole group is 29%, and respectively 49%, 38% and 9% for the groups A, B and C. The median disease free intervals are 43, 29 and 12 months respectively. Fifteen prognostic factors likely to influence overall survival or disease free survival were evaluated. With univariate analysis, 8 factors were found to be of individual prognostic value: extent of initial erythema, erythema present after initial chemotherapy, erythema present after radiotherapy, non menopaused status, tumor diameter greater than 10 cms, residual breast tumor (clinical or radiographic) after maintenance chemotherapy, supra clavicular adenopathy (N3). Age at the diagnosis, type of chemotherapy, or performance of a radical mastectomy did not influence the prognosis. Multivariate analysis using the Cox-model isolated 3 factors of bad prognosis: erythema involving the whole breast at initial diagnosis, erythema present at the end of initial chemotherapy, N3.
