Neoadjuvant Hypertermic Isolated Limb Perfusion in Treatment of Undifferentiated Spindle Cell Sarcoma of Lower Limb with Achieved Complete Pathologic Response.

BACKGROUND: Hyperthermic isolated limb perfusion uses therapeutic effect of hyperthermia in the bounded compartment of the limb together with increased concentration of chemotherapy effect than what would be achieved in systemic application. Gold standard was melphalan (Alkeran) in combination with tasonermin (Beromun, tumor necrosis factor alpha). The efficacy of this combination has been demonstrated in limb soft tissue sarcomas and in patients with limb isolated bulky disease of malignant melanoma. CASE: We describe a case of a 65-year-old female patient with undifferentiated spindle-cell sarcoma treated by a multidisciplinary team at the 2nd Surgical Clinic of Cardiovascular Surgery and Clinic of Oncology General University Hospital in Prague and at the Department of Orthopaedics Na Bulovce Hospital with the aim of preserving the limb despite the advanced disease. The patient underwent hyperthermic isolated limb perfusion with tasonermin and melphalan with partial response on magnetic resonance imaging. Subsequent wide resection was done with complete pathological remission according to histological examination maintaining a fully functional limb. The patient is followed without signs of recurrence. CONCLUSION: Hyperthermic isolated limb perfusion with tasonermin and melphalan is an important part of a multimodal approach in the treatment of extremity sarcomas with a high percentage of responses that increase the percentage of limbs retaining resections. Multidisciplinary team should consider this option in patients with localized limb sarcomas and should be performed in specialized centers with experience in this procedure.

Prevention of neural tube defects by folic acid - awareness among women of childbearing age in Slovakia.

BACKGROUND: Folic acid deficiency plays a central role in the aetiology of many congenital anomalies including neural tube defects. Protective effect of folic acid on embryo may be acquired only if taken periconceptionally. OBJECTIVES: The aim of the study was to investigate the awareness about folic acid among women of childbearing age in Bratislava, Slovakia. METHODS: There were 130 respondents involved in the research (106 pregnant women, 24 female students of medical faculty). Using questionnaire we acquired following data: pregnancy details, interest in diet before and during pregnancy, recommendations regarding nutrition and supplementation pre- and post-conception, knowledge about folic and other acid in 2004 and 2009. RESULTS: More than half of the respondents knew the sources of folic acid. The interest in the nutrition facts of the food dropped from 91 % to 58.5 %. The number of pregnant women advised about correct nutrition and folic acid supplementation before and during pregnancy increased from 16 % to 37 %. Planning the next gravidity with folic acid supplementation became greater than 21 % (38 % in 2009). Nevertheless, only 46 % of these women believed that proper food content with folic acid may prevent congenital anomalies. In a group of students planning to take folic acid periconceptionally the number raised up to 62.5 %. CONCLUSION: The results revealed low knowledge about the effect of folic acid on developing embryo among women of childbearing age. Effective intervention programs are needed with the aim to improve periconceptional intake of folic acid in 2004 and 2009. The results in both periods show low knowledge about this essential vitamin (Tab. 1, Fig. 8, Ref. 31).

[Use of allogenous material in the management of spina bifida aperta]. / Pouzitie alogénneho materiálu pri riesení spina bifida aperta.

AIM: "Conditio sine qua non" in the management of open neural tube defects includes closure of all layers with as minimum as possible tension left within the suture region, in order to prevent early, as well as long-term postoperative complications. In extensive fascial defects, the authors used the Gore-Tex patch as an alternative to myofascial or fasciocutaneous flaps. PATIENTS AND METHODS: From January 2004 to January 2008, 23 patients suffering from open spina bifida underwent surgery in the Bratislava Pediatric Surgery Centre. In 17 subjects, the fascia was sutured following a myofascial release, in 2 subjects the suture was secured with tissue adhesive. In 4 subjects, the Gore-Tex patch was implanted to secure the "tension free" plasty; the Gore-Tex Dual Mesh was used in 2 subjects as well as the Gore-Tex Spinal. RESULTS: Two subjects, who had the Gore-Tex Dual Mesh implanted, developed sequestration of the implant during the late postopertive period. Upon reoperation, the authors removed the Gore-Tex Dual Mesh in the both subjects. However, they found a firm fibrous membrane, which was considered sufficient to protect the dural sac. On the contrary, the both subjects who had the Gore-Tex Spinal implanted, healed with no complications recorded. CONCLUSION: Based on the experience, the Gore-Tex Dual Mesh, although implanted lege artis, does not appear a suitable material for fascia replacements in open spina bifida plastic procedures. Further experience will give more evidence, whether Gore-Tex Spinal would be a suitable alternative, however, the courses in the 2 subjects have hitherto been encouraging.
