Treatment of giant cell tumours of bone by radical curettage and bone cement

Background: Giant cell tumour of bone remains a difficult and challenging management problems because there are no absolute clinical radiographic or histologic parameters that accurately predict the tendency of any single lesion to recur or metastasize.Methods: We performed surgery on 12 patients of GCT with radical curettage and bone cement over a period of 5.8 years. Results were evaluated using the musculoskeletal skeletal grading system.Results: The present series consists of 12 case of GCT age ranging from 16-45 years. Painful swelling was the commonest presentation, limitation of motion was seen in 9 cases and pathological fracture was seen in 1 case. 9 of the tumour occurred around knee joint. Rare involvement of talus was seen in 1 case. Overall 9 patients had a perfect functional score of 30 points and 1 patient scored less than 20 points.Conclusions: Acrylic cement reconstruction is safe and effective procedure that provides local adjuvant therapy, the cement field defect is mechanically stable. Patient can bear weight immediately and rehabilitate quickly

Disposal of Household Wastewater in Soils of High Stone Content (1981-1983)

Four experimental filter fields were constructed with built-in monitoring equipment in Nixa soils. These soils contain many chert fragments and a fragipan about 60 cm below the soil surface. The fragipan restricts downward movement of water and is the designlimitingfeature. The four filter fields were: 1. A standard filter field, 76 cm deep. The bottom of the trench was in the fragipan. 2. A modified standard filter field, 30 cm deep. The bottom of the trench was above the fragipan. 3. A modified pressure filter field, 40 cm deep. The bottom of the trench was above the fragipan. In addition, a pressure-distribution system was used to insure uniform distribution of effluent in the trench. Inadvertently, this field was installed in a different soil, and the results cannot be compared directly with the other three. 4. Another modified pressure filter field with the bottom of the trench only 6 cm below the soil surface. Observation of these systems confirms that placing filter fields higher in the soil above the hydraulically limiting horizon results in improved hydraulic performance. The presence of the fragipan amplified the adverse effects attributable to climatic stress. The seepage beds which are higher in the soil profile are able to handle the effluent load and climate load with less danger of surfacing

Atmospheric circulation patterns, cloud-to-ground lightning, and locally intense convective rainfall associated with debris flow initiation in the Dolomite Alps of northeastern Italy

The Dolomite Alps of northeastern Italy experience debris flows with great frequency during the summer months. An ample supply of unconsolidated material on steep slopes and a summer season climate regime characterized by recurrent thunderstorms combine to produce an abundance of these destructive hydro-geologic events. In the past, debris flow events have been studied primarily in the context of their geologic and geomorphic characteristics. The atmospheric contribution to these mass-wasting events has been limited to recording rainfall and developing intensity thresholds for debris mobilization. This study aims to expand the examination of atmospheric processes that preceded both locally intense convective rainfall (LICR) and debris flows in the Dolomite region. 500 hPa pressure level plots of geopotential heights were constructed for a period of 3 days prior to debris flow events to gain insight into the synoptic-scale processes which provide an environment conducive to LICR in the Dolomites. Cloud-to-ground (CG) lightning flash data recorded at the meso-scale were incorporated to assess the convective environment proximal to debris flow source regions. Twelve events were analyzed and from this analysis three common synoptic-scale circulation patterns were identified. Evaluation of CG flashes at smaller spatial and temporal scales illustrated that convective processes vary in their production of CF flashes (total number) and the spatial distribution of flashes can also be quite different between events over longer periods. During the 60 min interval immediately preceding debris flow a majority of cases exhibited spatial and temporal colocation of LICR and CG flashes. Also a number of CG flash parameters were found to be significantly correlated to rainfall intensity prior to debris flow initiation

Teknologi Pembuatan Perahu Tradisional oleh Masyarakat di Sekitar Danau Tigi Kampung Puyai

Penelitian ini bertujuan untuk mengetahui jenis kayu dan teknik pembuatan serta pemeliharaan dan pola transfer pengetahuan dari proses pembuatan perahu. Metode penelitian yang digunakan yaitu metode deskriptif dengan teknik wawancara semistruktural dan observasi langsung di lapangan. Hasil penelitian menunjukkan bahwa terdapat 12 jenis kayu dari 7 famili yang digunakan oleh masyarakat Kampung Puyai sebagai bahan baku pembuatan perahu tradisional. Terdapat 3 (tiga) jenis kayu yang sering digunakan untuk badan perahu yaitu Digi (Nothofagus recurva Steenis), Epo (Eugeniaanomala), Danmoane (Toona sp.). Proses pembuatan perahu meliputi pembagian batang, pembentukan perahu, penghalusan, penyelesaian (finishing), penarikan perahu ke danau dan pengujian kelayakan perahu. Pemeliharaan dilakukan untuk mencegah terjadinya  kerusakan perahu antara lain: pembersihan setiap kali pemakaiaan, perbaikan secara menyeluruh, perlindungan terhadap perahu dari panas matahari. Pola transfer pengetahuan pembuatan perahu secara tradisional kepada generasi berikutnya dilakukan dengan cara mengajak para pemuda untuk ikut serta dalam proses pembuatan perahu.&nbsp

Bone hydatid disease of distal femur and diaphysis of tibia: report of two cases with review of literature

Cystic echinococcus or hydatidosis is a parasitic infection of humans and animals. In this we are reporting 2 cases. one is hydatid disease at distal femur left side and other patient having hydatid disease at shaft tibia rt side. both cases investigated and definitive surgery was done as arthrodesis with long tibio-femoral nail for distal femoral hydatidosis and curettage for tibial hydatidosis. Both patient given albendazole and followed up. in recent follow-up both cases do not have signs of recurrence. hence case report of these two cases is discussed along with review of literature

What causes the irregular cycle of the atmospheric tape recorder signal in HCN?

Variations in the mixing ratio of long-lived trace gases entering the stratosphere in the tropics are carried upward with the rising air with the signal being observable throughout the tropical lower stratosphere. This phenomenon, referred to as "atmospheric tape recorder" has previously been observed for water vapor, CO2, and CO which exhibit an annual cycle. Recently, based on Microwave Limb Sounder (MLS) and the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) satellite measurements, the tape recorder signal has been observed for hydrogen cyanide (HCN) but with an approximately two-year period. Here we report on a model simulation of the HCN tape recorder for the time period 2002-2008 using the Chemical Lagrangian Model of the Stratosphere (CLaMS). The model can reproduce the observed pattern of the HCN tape recorder signal if time-resolved emissions from fires in Indonesia are used as lower boundary condition. This finding indicates that inter-annual variations in biomass burning in Indonesia, which are strongly influenced by El Nino events, control the HCN tape recorder signal. A longer time series of tropical HCN data will probably exhibit an irregular cycle rather than a regular biannual cycle. Citation: Pommrich, R., R. Muller, J.-U. Grooss, G. Gunther, P. Konopka, M.
