Reverse LISS plating for intertrochanteric Hip Fractures in elderly patients
CQ Zhang, Y Sun, DX Jin, C Yao, SB Chen, BF Zeng
BMC Musculoskeletal Disorders , 2010, DOI: 10.1186/1471-2474-11-166
Abstract: We treated 28 elderly patients with a mean age of 82.3 years. According to the Evens classification, there were 2 Type I fractures, 2 Type II fractures, 3 Type III fractures, 13 Type IV fractures, 6 Type V fractures and 2 Type R fractures. All fractures were treated using the reverse LISS. Radiographic and clinical evidence of functional outcome and complications were evaluated.Mean perioperative blood loss was 92.4 milliliters (range 35 to 245 milliliters), and the mean postoperative hospital stay was 8.7 days (range 3 to 14 days).Complications included one minor wound hematoma. Radiographically, no collapses, screw cutouts, or head penetrations were seen. All surviving patients (28 of 28; 100 percent) had uneventful fracture healing with union achieved by six months in all patients.Use of the Reverse LISS plating for intertrochanteric hip fractures resulted in event-free fracture healing.Hip fractures are a leading cause of death and disability among the elderly. Approximately 50% of hip fractures are intertrochanteric fractures, a large percentage of which are unstable [1,2]. Treatment goals for this patient population include early rehabilitation, restoration of the anatomic alignment of the proximal part of the femur, and maintenance of the fracture reduction [3]. Different approaches have been used to solve this problem, including trochanteric osteotomy techniques, cementing, and different types of fixation devices. Despite improved techniques and devices, failure of fixation is still a problem in unstable intertrochanteric fractures[4].In recent years, the minimally invasive surgical techniques have led to a widespread use of many new implants [5,6]it has been shown that they can reduce operative complications and postoperative morbidity. As such, the present study evaluates the treatment of intertrochanteric hip fractures with the reverse LISS plating system.The present study was reviewed and approved by our institutional review board, and informed consent w

Public Issues Education and Extension Practice in Nigeria
BF Umar
Journal of Agricultural Extension , 2011,
Abstract: This paper advocates that public issues education (PIE) and conflict management are new societal concerns extension professionals in Nigeria should tackle. The paper believes that incorporating PIE into policy making will allow communities in Nigeria to use public-issue conflicts as an opportunity to collaboratively explore topics, better understand the issues, and consider alternative solutions. The paper provides an overview of the concept of PIE, the process of public policy education and how PIE helps communities involved in public-issue disputes to reach agreements. Furthermore, the paper identifies (1) roles extension professionals in Nigeria should play in PIE; (2) principles they should observe to successfully impart policy education; (3) ways for evaluating the success of PIE; and (4) institutional requirements for involvement of extension professionals in PIE in Nigeria. The paper concludes that involvement of extension professionals in PIE can only be possible when the institutional environment of extension agencies in the country gives it a worthy support. The extension professionals also will require training on the principles and process of PIE and the ability to practically apply skills so acquired for them to effectively impart public policy education.

Pollination efficiency of Apis mellifera Linnaeus, 1758 (Hymenoptera, Apidae) on the monoecious plants Jatropha mollissima (Pohl) Baill. and Jatropha mutabilis (Pohl) Baill. (Euphorbiaceae) in a semi-arid Caatinga area, northeastern Brazil

Abstract: previous studies have shown the superior competitive ability of honeybees compared with native bees in the exploitation of floral resources and nesting sites besides their low efficiency in pollinating native plant species. however, there is little evidence of the effect of this invading species on autochthonous plant populations in natural environments. thus experiments were performed to test the pollination efficiency of honeybees in two species of jatropha (euphorbiaceae), j. mollissima (pohl) baill. and j. mutabilis (pohl) baill., after a single flower visitation. samplings were carried out between march and april 2006 in a hyperxerophilous shrub-arboreal caatinga at esta??o biológica de canudos, bahia (9o 56′ 34" s, 38o 59′ 17" w), the property of funda??o biodiversitas. apis mellifera was efficient at pollinating j. mollissima (100%) and j. mutabilis (85%). this high efficiency may be explained by 1) the simple floral characteristics of both plant species, which facilitate access to the sexual organs of the plant; and 2) the body size of a. mellifera that fits the flower's dimensions.
Studies on arbuscular mycorrhisation of papaya
WS Khade, BF Rodrigues
African Crop Science Journal , 2009,
Abstract: Carica papaya L. is known to exhibit a strong growth response to colonisation by arbuscular mycorrhizal fungi; yet it is generally believed that mycorrhizal growth effects are primarily nutritionally mediated and are inversely related to improved soil fertility, especially available soil P, which affects the fungus symbiotic effectiveness. This study was, therefore, undertaken to evaluate the influence of selective arbuscular mycorrhizal fungi on vegetative growth of Carica papaya L. Studies were carried out in India on mycorrhization of Carica papaya var. Surya seedlings. The experiment comprised of un-inoculated seedlings, seedlings inoculated with Glomus intraradices, seedlings inoculated with Glomus mosseae and seedlings inoculated with mixed inoculum [Glomus intraradices + Glomus mosseae]. Inoculation with arbuscular mycorrhizal fungi significantly (P<0.05) increased all the growth parameters viz., plant height, stem girth, leaf area and root length. Mycorrhizal plants exhibited significant increase in fresh and dry weights of shoot and root systems. A higher root: shoot ratio was also observed in mycorrhizal plants than the control plants. Glomus mosseae was the most effective species of arbuscular mycorrhizal fungi, recording the highest root colonisation and exerting profound influence on growth of papaya.
The prevalence of exercise-induced asthma among school children
BF Mtshali, KE Mokwena
South African Family Practice , 2009,
Abstract: Exercise-induced asthma (EIA) is one of the major factors that affect optimal performance in sport. The prevalence of EIA is reported to be on the increase among school children worldwide. The aim of this study was to indicate EIA prevalence among primary-school children in South Africa. A field study determined the prevalence of EIA. A convenience sample of 127 children aged 8 to 16 years was selected. A health- screening questionnaire was used. The criteria for selection were that the subjects should be non- asthmatics and should not have any other illness during the screening that could interfere with the results. Peak expiratory flow rate (PEFR) was measured pre- and post-exercise using an ASSESS peak flow meter. The subjects did a six-minute run on a school playground. The post-exercise PEFR was measured within 10 minutes of exercise. The determinant of EIA was ≥ 10% decrease in PEFR after exercise. A total of 112 (88%) subjects participated in the study. Fifteen subjects were excluded (eight had asthma, five had respiratory tract infection and two had other illnesses). The average exercise heart rate was ± 80% of predicted maximal heart rate. The prevalence of EIA was 23% (n = 26). The incidence of a history of allergic rhinitis was statistically significantly increased among those with positive tests (p = 0.027). This study highlights the need to screen all children so that EIA can be determined and addressed appropriately.
The 1950-1998 warm ENSO events and regional implications to river flow variability in Southern Africa
BF Alemaw, TR Chaoka
Water SA , 2006,
Abstract: The variability of annual river runoff and its possible association with the 1950-1998 seasonal El Ni o/Southern Oscillation (ENSO) is investigated in 502 rivers gauged in 9 countries of the Southern African region. We found some evidence of possible links between available surface water resources in terms of mean annual runoff and warm ENSO events. This was revealed by the existence of strong and nearly-strong positive linear correlation between annual discharges and the warm seasonal ENSO indices explained by the sea level pressure (SLP) data. Of the 502 rivers we considered, 150 rivers exhibit strong positive correlation between the December to February quarter ENSO indices and the annual runoff – with 25% of the variance in annual runoff being accounted for by the warm ENSO events. A relatively weaker positive correlation also occurred in 174 rivers we considered. The strong positive correlation occurs in parts of Zambia, Namibia, Mozambique and the lowveld in South Africa. In these parts of Southern Africa, there is evidence of a general decline in annual runoff after the mid-1970s compared to the period before it. These revelations are explored and are found to be partly explained by the high frequency of drought-related warm ENSO phenomena that occurred during the same period.
