Prolonged neuromuscular blockade with mivacurium in a newborn

Recent reports have demonstrated that puerperal psychosis is preceded by prodromic signs. These signs must be recognized in a multidisciplinary context, opening the way to improved diagnosis, therapy and prognosis. On the basis of our clinical experience, we stress the important of early management in women who present prodromic signs of puerperal psychosis. Specific management relies on intensive psychotherapy with daily sessions centered on filiation. With this approach, the emergence of delusions can generally be prevented, usually allowing an uninterrupted mother-infant relationship. We hypothesize that this approach has a favorable influence on later mother-child interactions and cause profound changes in the mother's psychic organization, resulting in a better long-term prognosis. We illustrate our point with a case report.     

Two reconstructive techniques for flatfoot deformity comparing contact characteristics of the hindfoot joints

The effect of two different methods of reconstruction of flatfoot deformity and the role of the posterior tibial tendon on the contact characteristics of the hindfoot joints were quantified using pressure-sensitive film. Each of 10 cadaver feet was loaded quasi-statically by an axial compressive force to simulate varying loads. First, a specimen was tested intact, then it was tested after sectioning the spring ligament and loading the specimen cyclically to create one type of flatfoot deformity. It was then tested again after reconstructing the deformity. Reconstructions used were the Dillwyn-Evans procedure (bone graft in osteotomy of the calcaneus) or the calcaneocuboid distraction arthrodesis (CCDA). We found that surgically produced flatfoot deformity altered mainly the talonavicular joint, by decreasing its contact area. The Dillwyn-Evans method had less effect on the talonavicular joint (altering 2 of 6 measured parameters) than the CCDA (3 of 6) and more effect on the anteriomedial facet (altering 3 of 6 parameters) than the CCDA (1 of 6). The Dillwyn-Evans method had more effect on the posterior facet (altering 2 of 6 measured parameters) than the CCDA (1 of 6). Function of the posterior tibial tendon had no effect on contact characteristics of the hindfoot joints after either type of reconstruction. These findings are based on measurements using a quasi-statically-loaded foot model at three selected positions, and results may be different with dynamic loading.     

Postsurgical bile leaks: endoscopic obliteration of the transpapillary pressure gradient is enough

OBJECTIVES: Bile leaks are a well documented complication of biliary surgery, occurring more frequently with laparoscopic procedures. Endoscopic therapy with a long biliary endoprosthesis traversing the site of the leak is effective. We have evaluated the hypothesis that equalizing biliary and duodenal pressures with a short transpapillary stent is an equally effective therapy for bile leaks. METHODS: Thirty one consecutive patients presenting over a 52-month period with postsurgical bile leaks were evaluated. Patients had been treated with long endoprostheses (stents or nasobiliary tubes), sphincterotomy, or short transpapillary stents. The success, complication rate, need for additional therapy, and hospitalization time of each therapeutic approach were determined. RESULTS: Endoscopic therapy was successful in all 25 patients in whom a bile leak could be documented. The clinical success, need for radiological drainage, length of hospitalization, and incidence of pancreatitis were similar for all methods of treatment. CONCLUSIONS: These results confirm that endoscopic therapy is highly successful in the treatment of postoperative bile leaks and suggest that the mechanism of healing is the equalization of bile duct and duodenal pressures, allowing flow of bile into the duodenum. The endoscopic placement of short transpapillary stents without sphincterotomy is a temporary, effective, and technically simple method of pressure equalization. This should be considered as the primary therapy for most postoperative bile leaks.     

Primary retroperitoneal germ cell tumours: excision via a thoracoabdominal extraperitoneal approach

BACKGROUND: Primary retroperitoneal germ cell tumours usually present as a large abdominal mass in young men. The testes are normal on examination and ultrasonography but there are usually raised serum levels of human chorionic gonadotrophin and/or alpha-fetoprotein. METHODS: Fourteen men (median age 33 years) with primary retroperitoneal germ cell tumours were treated by chemotherapy followed by surgical resection of the primary tumour and metastases via a thoracoabdominal extraperitoneal approach. RESULTS: There was minimal morbidity. The survival rate was 13 of 14 and the disease-free survival rate was 11 of 14 after a median follow-up of 15 months. CONCLUSION: The thoracoabdominal extraperitoneal approach for the removal of retroperitoneal germ cell tumours and their metastases after chemotherapy improves tumour clearance, morbidity and recovery time compared with the transperitoneal anterior approach.     

The medical technological aspects of the development of laser therapy apparatus

Three variants of narcosis were compared in order to choose the optimal anesthesia for traumatic surgery involving blood loss of 15, 15 to 30, and more than 30% of the due volume of circulating blood. Microcirculation of the eye conjunctiva, central hemodynamics, hemostasis system, and lipid peroxidation were studied. Calypsol-based non-inhalation multicomponent intravenous anesthesia including neuroleptanalgesia and seduxen was found to be the least toxic and indicated for patients subjected to traumatic surgery involving blood loss of more than 30%.     

Designing drugs for transport into the brain

Research findings regarding general self-concept, academic self-concept, and self-awareness in students with learning disabilities have varied, and results are still inconclusive regarding the consistency between students' and teachers' judgments of academic performance. The current study focuses on students' and teachers perceptions of the students' strategy use and performance in nine different academic and organizational domains. Six hundred sixty-three students and their 57 teachers were involved in the study. Findings indicated that the students with learning disabilities considered themselves appropriately strategic and competent in the five domains of reading, writing, spelling, math, and organization. These students also rated their academic performance and organization as average to above-average in seven of nine domains, with the exception of checking and planning their work. Nevertheless, the self-ratings of the students with learning disabilities were still significantly lower than the self-ratings of average achievers in virtually all domains. The second major set of findings revealed a sharp discrepancy between the self-assessments of the students with learning disabilities and their teachers' judgments. Teachers rated the students with learning disabilities as weak in their strategy use and below-average in their performance in all nine academic and organizational domains. Finally, gender differences were not evident in eight of the nine domains. These results have added to the increasing body of literature indicating that students with learning disabilities frequently perceive themselves as capable and effective and often rate themselves as academically stronger than their teachers judge them to be.     

Matrix metalloproteases and their inhibitors in the pleura

Vulvovaginal candidiasis is a frequent inflammatory process in women but it has not been widely studied in female sex workers (FSWs). To estimate the frequency of Candida species infection in FSWs and to identify related risk factors and clinical findings, we carried out a retrospective study of 1923 FSWs over 11 years. We also performed a prospective study of 163 consecutive FSWs with a history of candidiasis during a 4-year period. Candida species were isolated in 1967 samples (18.5% of the total). Candida albicans (89.3%) was the most frequent species, followed by Candida glabrata (2.7%), Candida parapsilosis (1.2%) and Saccharomyces cerevisiae (0.4%). In the prospective study of 163 patients, we found vaginal discharge in 76.1% of cases, soreness in 52.1% and vulval pruritus in 32.5%. We identified 12 patients (7.4%) with recurrent vulvovaginal candidiasis. No statistical difference was found between recurrent vulvovaginitis and the use of oral contraceptives, oral sex, tight-fitting clothing and synthetic underwear. FSWs have the same prevalence of candidiasis as other groups of women described in published literature. The proportion of albicans and non-albicans species does not differ between women with recurrent and non-recurrent vulvovaginal candidiasis (VVC).
