Visual inspection with acetic acid for cervical cancer screening outside of low-resource settings.

OBJECTIVES: To assess visual inspection with acetic acid (VIA) as a screening tool for use in a well-equipped health center in Peru, to evaluate VIA as an alternative or adjunct to the Papanicolaou (Pap) smear, and to determine if VIA can play a role in settings other than low-resource ones. METHODS: This was a prospective study of 1 921 asymptomatic women living in Lima, Peru, carried out in 1999 and 2000. The study was performed at a cancer center equipped with the latest-generation technology and highly trained oncologists. The women underwent a complete clinical evaluation, including a Pap smear and VIA. Participants with any positive test were referred for colposcopy and biopsy. RESULTS: More women tested positive by VIA than on the Pap smear (6.9% vs. 4.2%; P = 0.0001). There were 35 women with histologic cervical intraepithelial neoplasia grade 1 (CIN 1); of these, 15 were detected by Pap and 20 by VIA (P = 0.4). A diagnosis of CIN 2 or 3 (CIN 2-3) was confirmed in a total of 13 cases; Pap detected 5 of the cases and VIA 11 of the cases (P = 0.06). The positive predictive value for detection of CIN 2+ was 8.3% for VIA and 6.3% for Pap (P = 0.5). Most importantly, while only 2.3% of patients with a positive VIA were lost to follow-up before colposcopy, that was true for 26.3% of the women with a positive Pap smear (P < 0.0001). CONCLUSIONS: VIA is useful for detection of precursor lesions of cervical cancer not only in low-resource settings but also in well-equipped health centers and cancer centers. In these non-low-resource settings, VIA has a positive predictive value comparable to the conventional Pap smear, but it is more likely to achieve earlier diagnosis, follow-up, and treatment than cytology-based screening.

Clinical Impact of 18F-FDG-PET in the Suspicion of Recurrent Ovarian Carcinoma Based on Elevated Tumor Marker Serum Levels

Purpose: To retrospectively evaluate the contribution of 18F-fluorodeoxy-glucose-positron emission tomography (FDG-PET) to the diagnosis and clinical management of patients who were suspected of recurrent ovarian carcinoma, based on elevated tumor markers levels with normal or equivocal computed tomography (CT) or nuclear magnetic resonance (NMR).Procedures: 20 patients with these characteristics underwent FDG-PET. PET findings were confirmed in 14, in 7 by surgery, and in the other 7 by clinical course.Results: Recurrence was confirmed in 12 patients, all with FDG-PET positive. In other 2, recurrence was rule out and in 1, FDG-PET was negative. FDG-PET accuracy was 93% with 4 surgeries avoided and guided other 6.Conclusions: FDG-PET is an useful technique for detecting recurrent ovarian carcinoma suspected by elevated tumor markers levels and normal or equivocal results in the morphologic imaging techniques and has an important clinical impact on the management of these patients.     

Treatment of osteoarthritis of the knee with valgus deformity by means of varus osteotomy

Nineteen cases of osteoarthritis of the knee with valgus deformity in 17 patients were treated by femoral supracondylar varus osteotomy (17 cases) or by high tibial varus osteotomy (2 cases) over the last 15 years. Fixation was performed using a 95 degrees AO blade-plate in 13 of the femoral osteotomies and a straight plate in the other four. The mean follow-up time was 6.5 years. The valgus deformity was idiopathic in 14 cases, secondary to rheumatoid arthritis in 2 cases and to tibial valgus in one case. The Hospital for Special Surgery (HSS) score was used to evaluate the clinical results: nearly 75% were excellent or good. The causes related to poor results are analyzed regarding indication and surgical technique. It appears that varus osteotomy is an effective procedure for the treatment of osteoarthritis of the knee with valgus deformity, above all in order to alleviate pain, although the operation requires precision, and correct selection of patients is of prime importance.     

Treatment of proximal hypospadias with a tubularized island flap urethroplasty and the onlay technique: a comparative study

BACKGROUND/PURPOSE: The onlay island flap urethroplasty was first described in the repair of mid and distal penile hypospadias. Since then, this technique has been increasingly used in more severe cases of hypospadias, because of the complications of tubularized flaps, mainly megaurethra and proximal anastomotic strictures. The aim of this study was to compare the morbidity of these 2 techniques. METHODS: Between April 1994 and December 1998, 80 patients underwent surgical treatment for hypospadias. A tubularized island flap (Ducketttechnique) was performed in 42 cases, and the onlay island flap technique was used in 38 patients. The authors retrospectively compared the complication rate and type of these 2 procedures. RESULTS: Altogether, fistula was the most frequent complication without any significant difference between the 2 groups (21.4% for Duckett technique and 18.4% for onlay repair; P > .05). However, the anastomotic stricture was much more common in the tubularized flap group (7.14% v 2.63%; P < .05). Moreover, a megaurethra was found only in the Duckett technique group (4.7%). There was no case of chordee recurrence, but 6 patients (15.7%) treated with the onlay technique required urethrolysis including dissection of the chord behind the urethral plate, and in the other 3 patients of the same group (7.9%), a dorsal Nesbit plication also was necessary. In all these cases, the urethroplasty included an island cutaneous flap to provide ventral coverage to the neourethra. CONCLUSIONS: The authors conclude that both techniques present similar complications. However, proximal strictures and megaurethra are more common after the Duckett technique. This procedure is of choice in patients with scrotal hypospadias. Conversely, the onlay repair should be completed with other procedures (urethrolysis, dorsal Nesbit plication) to obtain good results in patients with severe degree of chordee.     

Satisfaction with provider communication among Spanish-speaking Medicaid enrollees.

OBJECTIVE: To determine if differences between English- and Spanish-speaking parents in ratings of their children's health care can be explained by need for interpretive services. METHODS: Using the Consumer Assessment of Health Plans Survey-Child-Survey (CAHPS), reports about provider communication were compared among 3 groups of parents enrolled in a Medicaid managed care health plan: 1) English speakers, 2) Spanish speakers with no self-reported need for interpretive services, and 3) Spanish speakers with self-reported need for interpretive services. Parents were asked to report how well their providers 1) listened carefully to what was being said, 2) explained things in a way that could be understood, 3) respected their comments and concerns, and 4) spent enough time during medical encounters. Multivariate logistic regression was used to compare the ratings of each of the 3 groups while controlling for child's gender, parent's gender, parent's educational attainment, child's health status, and survey year. RESULTS: Spanish-speaking parents in need of interpretive services were less likely to report that providers spent enough time with their children (odds ratio = 0.34, 95% confidence interval = 0.17-0.68) compared to English-speaking parents. There was no statistically significant difference found between Spanish-speaking parents with no need of interpretive services and English-speaking parents. CONCLUSIONS: Among Spanish- versus English-speaking parents, differences in ratings of whether providers spent enough time with children during medical encounters appear to be explained, in part, by need for interpretive services. No other differences in ratings of provider communication were found.     

Peripheral nervous system neurotoxicity secondary to chemotherapy treatment]

Peripheral neurotoxicity is a crucial side effect of chemotherapeutic agents. It is the only situation where there is no preventive treatment. Neuromuscular toxicity has become the major dose limiting side effect for many chemotherapeutic agents. The iatrogenic toxic neuropathy is a growing neurologic problem, as cancer patients are beign treated with increasing doses of chemotherapy drugs. Major advances in cancer treatment have resulted from the use of drug combinations; for some combinations this raises the possibility of sinergistic neurotoxicity. The following report reviews the SNP toxicities encountered with cisplatin, vincristine, taxanes and others, and methods to minimize the deleterious effect of chemotherapeutic agents.     

Recurrent remodeling after ventricular assistance: is long-term myocardial recovery attainable?

BACKGROUND: Long-term left ventricular assist devices (LVAD) have been used both as a bridge to heart transplantation and to recovery of native myocardial function. Despite much evidence for reversal of some of the structural and functional changes present in the failing heart during LVAD support, clinical evidence for sustained myocardial recovery is scant. We describe 2 patients in whom myocardial recovery during LVAD support led to device explanation only to have heart failure recur. This necessitated a second LVAD implantation, a process that we have termed recurrent remodeling. METHODS: The medical records of 2 patients with cardiomyopathy supported with HeartMate LVADs (Thermo Cardiosystems, Inc, Woburn, MA) were retrospectively reviewed. RESULTS: One patient was supported with an LVAD for 2 months, at which time the LVAD was explanted. Progressive deterioration of cardiac function followed, requiring a second LVAD 19 months after LVAD explanation. After 2 months of further LVAD support, a second episode of apparent myocardial recovery was observed during a period of device malfunction. The other patient was supported with an LVAD for 12 months, at which time the LVAD was explanted. The patient experienced progressive hemodynamic deterioration and required a second LVAD 6 months after LVAD explantation. Heart transplantations of both patients were successful. CONCLUSIONS: Our understanding of myocardial recovery in the setting of hemodynamic unloading with LVAD support has not yet progressed to the point where we are able to accurately predict successful long-term LVAD explantation. The evolution of reliable predictors of sustainable myocardial recovery will help to avoid further cases of recurrent remodeling requiring repeat LVAD implantation.
