Impact of Gensingen brace treatment on Lenke 5 curvatures and chronic low back pain in late adolescent and adult scoliosis patients.

Background: Lenke 5C (lumbar and or thoracolumbar) curve patterns lead to loss of lumbar lordosis which is associated with low back pain in later adulthood. We undertook our study to investigate if brace treatment may have an effect on low back pain and on improving the cosmetic appearance in late adolescents and adults. Objectives: To estimate if conservative treatment may have an effect on pain in single lumbar curvatures in late adolescent and adult patients with Adolescent Idiopathic Scoliosis (AIS) using a Gensingen Brace by Weiss (GBW). Method: We investigated AIS patients with Lenke 5C pattern who wore a GBW prospectively. The inclusion criteria of our study were age over 15 years, Cobb angle greater than 20° before treatment and Risser 4 or 5. A verbal pain rating scale was used (no pain, mild pain, moderate pain, severe pain, very severe pain). Results: A total of 26 patients met the inclusion criteria. The average age was 17.7 years and the average Cobb angle was 41.5°. Nineteen patients (73.1%) experienced mild or moderate chronic low back pain before treatment and seven patients (26.9%) were asymptomatic but seeking treatment for cosmetic reasons. At follow-up, a 23% correction of the curve was achieved. All previously symptomatic patients reported that they no longer experienced low back pain after having worn the brace regularly. Conclusion: High correction bracing seems to have a positive effect on the curve and on chronic low back pain in patients with a scoliosis and a Lenke 5C curve pattern. Clinical implications: High correction, pattern specific bracing with a GBW may be applied aiming at reducing structural curves and chronic low back pain in late adolescent and adult patients with AIS and with a single lumbar curvature.

Fires, Smoke Exposure, and Public Health: An Integrative Framework to Maximize Health Benefits From Peatland Restoration.

Emissions of particulate matter from fires associated with land management practices in Indonesia contribute to regional air pollution and mortality. We assess the public health benefits in Indonesia, Malaysia, and Singapore from policies to reduce fires by integrating information on fire emissions, atmospheric transport patterns, and population exposure to fine particulate matter (PM2.5). We use adjoint sensitivities to relate fire emissions to PM2.5 for a range of meteorological conditions and find that a Business-As-Usual scenario of land use change leads, on average, to 36,000 excess deaths per year into the foreseeable future (the next several decades) across the region. These deaths are largely preventable with fire reduction strategies, such as blocking fires in peatlands, industrial concessions, or protected areas, which reduce the health burden by 66, 45, and 14%, respectively. The effectiveness of these different strategies in mitigating human health impacts depends on the location of fires relative to the population distribution. For example, protecting peatlands through eliminating all fires on such lands would prevent on average 24,000 excess deaths per year into the foreseeable future across the region because, in addition to storing large amounts of fuel, many peatlands are located directly upwind of densely populated areas. We also demonstrate how this framework can be used to prioritize restoration locations for the Indonesian Peatland Restoration Agency based on their ability to reduce pollution exposure and health burden. This scientific framework is publicly available through an online decision support tool that allows stakeholders to readily determine the public health benefits of different land management strategies.

[PRESSURE ULCER TREATMENT EXPERIENCE AT CLINICAL DEPARTMENT OF PLASTIC, RECONSTRUCTIVE AND AESTHETIC SURGERY, DUBRAVA UNIVERSITY HOSPITAL: COMPARISON OF RESULTS RECORDED IN THE 2011-2016 AND 2003-2008 PERIOD].

Results of this clinical study on surgical treatment of pressure ulcers at Department of Plastic, Reconstructive and Aesthetic Surgery, Dubrava University Hospital showed that there was no difference between the 2011-2016 and 2003-2008 periods, indicating continuation of good surgical treatment planning and appropriate postoperative care. Despite the smaller number of hospitalized patients in the 2011-2016 period (31 patients and 42 reconstructive procedures), the number of reconstructive procedure was similar to the recent 2003-2008 period (47 patients and 57 reconstructive procedures). The best results of reconstruction of sacral region pressure ulcer were achieved with fasciocutaneous and musculocutaneous flaps. Whenever possible, depending on the extent of the defect, musculocutaneous flaps should be preferred for reconstruction. It is especially suitable for pressure ulcer recurrence. For ischial region reconstruction, good results can be obtained by mobilizing the semimembranosus and/or semitendinosus in defect gap. For trochanteric region, the tensor fascia lata flap is a good choice. For maximal functional and reconstructive results, a multidisciplinary approach in pressure ulcer treatment has the leading role in the modern concept of wound healing. Surgical treatment should always include radical debridement, ostectomy and well planned defect reconstruction. Conservative treatment should be support to surgical treatment with a focus on patient health care and high hygiene measures. In recent years (2011-2016), the usage of better conservative treatment led to reduction of patient hospital stay and surgical treatment of pressure ulcer. Further 'wound care' nurses training in Croatia can lead the trend towards advanced practice nursing in pressure ulcer prevention and conservative treatment.

Reversin increase the plasticity of bone marrow-derived mesenchymal stem cell for generation of cardiomyocyte in vitro.

AIM: to speed up transdifferentiation of bone marrow-derived stem cells into cardiomyocyte in vitro by inducing dedifferentiation of bone marrow-derived mesenchymal stem cell, before induction by 5-aza-2'-deoxycytidine into cardiomyocyte. METHODS: two-three months old 2.5 kg weight adult male New Zealanad Rabbits were anesthezied with ether, thigh bones were excised, and bone marrow cells were obtained by aspiration. RESULTS: in our experiments after 1 week of mesenchymal stem cell cultures, 20 nM reversin was given to induce dediferentiation and after 24 hours exposure with 9µM 5-aza-2-deoxycytidine, early phase of cardiomyocyte differentiation appeared as cultured cell were strongly positive for GATA-4 and weakly positive for MLC-2ά, although beating cardiomyocyte has not yet appeared at the end of experiment. These experiments also showed a marked CD34+ and c-kit+ gene expression on RT-PCR examination. CONCLUSION: reversine increase plasticity of bone marrow-derived mesenchymal stem cell to generate cardiomyocyte after 5-aza-2'-deoxycytidine induction. CD34+ and c-kit+ may be a marker for cardiomyocyte progenitor cells.

New haplotypes of the Plasmodium falciparum chloroquine resistance transporter (pfcrt) gene among chloroquine-resistant parasite isolates.

Mutations in the Plasmodium falciparum chloroquine resistance transporter (pfcrt) gene were examined to assess their associations with chloroquine resistance in clinical samples from Armopa (Papua) and Papua New Guinea. In Papua, two of the five pfcrt haplotypes found were new: SVIET from Armopa and CVIKT from an isolate in Timika. There was also a strong association (P < 0.0001) between the pfcrt 76T allele and chloroquine resistance in 50 samples. In Papua New Guinea, mutations in the pfcrt gene were observed in 15 isolates with chloroquine minimum inhibitory concentrations (MICs) of 16-64 pmol, while the remaining six isolates, which had a wild-type pfcrt gene at codon 76, had MICs of 2-8 pmol. These observations confirm that mutations at codon 76 in the pfcrt gene are present in both in vivo and in vitro cases of chloroquine resistance, and that detection of the pfcrt 76T allele could predict potential chloroquine treatment failures.

Configuration and localization of the nipple-areola complex in men.

The causes of bilateral absence of the nipple-areola complex in men are seldom congenital, but attributable rather to destruction as a result of trauma, or after mastectomy in female-to-male transsexuals and in male breast cancer, or after the correction of extreme bilateral gynecomastia. Such a bilateral loss becomes a major reconstructive challenge with respect to the configuration and localization of a new nipple-areola complex. Because there is very little information available in the literature, we carried out a cross-sectional study on the configuration and localization of the nipple-areola complex in men.A total of 100 healthy men aged 20 to 36 years were examined under standardized conditions. The first part of the study dealt with the configuration of the nipple-areola complex (dimensions, round or oval shape). The second part concentrated on the localization of the complex on the thoracic wall with respect to anatomic landmarks and in correlation to various parameters such as weight and height of the body, circumference of the thorax, length of sternum, and position in the intercostal space. Of the 100 subjects examined, 91 had oval and seven had a round nipple-areola complex. An asymmetry between the right and the left side was found in two cases. The mean ratio of the horizontal/vertical diameter of an oval nipple-areola complex was 27:20 mm and the mean diameter for a round nipple-areola complex was 23 mm. The center of the nipple-areola complex was in the fourth intercostal space in 75 percent and in the fifth intercostal space in 23 percent of the subjects. To localize the nipple-areola complex on the thoracic wall de novo, at least two reproducible measurements proved to be necessary, composed of a horizontal line (distance from the midsternal line to the nipple = A) and a vertical line (distance from the sternal notch to the intersection of line A, = B). The closest correlation for the horizontal distance A was given by the circumference of the thorax: A = 2.4 cm + [0.09 x circumference of thorax (cm)], (r = 0.68). The best correlation to calculate the vertical distance B was found using the distance A and the length of the sternum: B = 1.2 cm + [0.28 x length of sternum (cm)] + [0.1 x circumference of thorax (cm)], (R = 0.50). In cases of bilateral absence, we recommend creating an oval nipple-areola complex in men. The appropriate localization can be calculated by means of two simple equations derived from the circumference of the thorax and the length of the sternum.

Isolation from the Sorghum bicolor mycorrhizosphere of a bacterium compatible with arbuscular mycorrhiza development and antagonistic towards soilborne fungal pathogens.

A gram-positive bacterium with antagonistic activity towards soilborne fungal pathogens has been isolated from the mycorrhizosphere of Sorghum bicolor inoculated with Glomus mosseae. It has been identified as Paenibacillus sp. strain B2 based on its analytical profile index and on 16S ribosomal DNA analysis. Besides having antagonistic activity, this bacterium stimulates mycorrhization.

[Silicone breast implants and risk of carcinoma]. / Silikonski implantati za dojku i rizik od karcinoma.

Breast reconstruction, i.e. enlargement of the breast by use of silicone implants, has been performed for almost 40 years. Due to its qualities silicone is being widely used in different branches of surgery. New scientific and technological knowledge have resulted in a variety of types of silicone implants (sheet, filling). There is a great interest, but also controversies concerning the development of breast cancer and connective tissue disease in implant bearing patients. There is no evidence on the influence of silicone implants on the breast cancer development. Regardless of the presence of the implant, standard mammography, additional tangential projections, Eklund's maneuver, ultrasonography in addition to a careful clinical examination are sufficient for an adequate follow-up and detection of even minimal changes within the breast tissue.

[Aneurysms of the extracranial part of the carotid artery]. / Aneurizme ekstrakranijskog dijela karotidne arterije.

The purpose of this article is to take firm position on the surgical treatment of the carotid artery aneurysm on the basis of ten years of experience, considering their rare occurrence and significant pathology. From January 1984 to December 1994, ten patients with aneurysms or pseudoaneurysms of extracranial carotid arteries were diagnosed and operated in the Department of Vascular Surgery, Clinical Hospital "Sestre milosrdnice" in Zagreb. In the same period, eight hundred operations of extracranial carotid arteries were performed. Special emphasis is put on the etiology of the disease where atherosclerosis is prevalent, but cases of traumatic, mycotic and postoperative aneurysms are also shown. In symptomatology, signs of palpable local tumor dominated in six patients, while in three patients central nervous system symptoms were found. All patients with neurologic symptoms were in the group with atherosclerotic aneurysms. In nine patients resection of the aneurysm and reconstruction with the interposition of a part of vena saphena magna or with allograft was performed. In one patient, neoanastomosis of the internal carotid artery in the common carotid artery was performed following the resection of a small aneurysm. In the early postoperative period there was no morbidity nor mortality. In view of frequent preoperative neurologic complications and good postoperative results, surgical treatment is indicated in all cases. Reconstruction is always indicated, and the procedure of choice is reconstruction with the interposition of a part of great saphenous vein.
