    Screening mammography identifies suspicious, non palpable mammary lesions. Mammographic needle localization (MNL) is currently being used to facilitate excision biopsy of these lesions. Thirty-two patients underwent biopsies of the breast after MNL for non-palpable lesions. Mammographic indications for biopsy consisted of microcalcifications (48%), mass or abnormal density (21%) or mass+abnormal density (24%). The carcinoma was identified in four cases (12%). Two of these were in situ, one was microinvasive and one was frankly invasive. Three were treated with a modified radical mastectomy. One of these non palpable lesion demonstrated nodal metastasis but none showed distant metastasis. All radiologically detected abnormalities were removed and confirmed with repeat radiology. No complications were identified. MNL effectively localizes non-palpable lesion of the breast and compliments accurate diagnosis and treatment of early carcinoma of the breast

    Learning results of physics at SMPN 1st Natar is not maximum because of the conventional teaching method of the teachers. This research compared the learning results of Exclusive model with direct instruction (DI) model, the purpose was to find out the differences between learning results of Exclusive model with DI model and to investigate which models that has higher average. The population was all students of VIII class at SMPN 1 Natar and the samples were students of VIII E and VIII F with Purposive Sampling method. The research design was Pre-Experimental Design with One Group Pretest-Posttest Design type. The hypothesis was analized by using normalize test and Independent Sample t-test, the results of Independent Sample t-test indicated that t-value cognitive result was 3.35, affective was 4.26, and psychomotor was 9.47 higher than t-table (2.04), it means that there were differences of average learning result of Exclusive model with DI model, and the average of Exclusive model was higher than DI model.Hasil belajar Fisika siswa di SMPN 1 Natar belum maksimal disebabkan cara mengajar guru yang konvensional. Penelitian ini membandingkan hasil belajar model Exclusive dengan model Direct instruction (DI), bertujuan untuk mengetahui perbedaan hasil belajar model Exclusive dengan model DI dan manakah yang rata-rata hasil belajarnya lebih tinggi. Populasi penelitian ini yaitu seluruh siswa kelas VIII dan sampelnya yaitu siswa kelas VIII E dan VIII F dengan metode Purposive Sampling. Disain penelitian berupa Pre-Eksperimental Design dengan tipe One Group Pretest-Posttest Design. Hipotesis dianalisis menggunakan uji normalitas dan uji Independent Sample t-test, diperoleh nilai t-hitung kognitif (3.35), afektif (4.26), dan psikomotor (9.47) lebih besar dari t-tabel (2.04), artinya ada perbedaan rata-rata hasil belajar model Exclusive dengan model DI serta rata-rata hasil belajar siswa pada kelas Exclusive lebih tinggi dibandingkan dengan kelas DI

    Program Keluarga Berencana adalah upaya peningkatan kepedulian dan peran serta masyarakat melalui pendewasaan usia perkawinan, pengaturan kelahiran, pembinaan ketahanan keluarga, peningkatan kesejahteraan keluarga kecil, bahagia dan sejahtera. Di Indonesia metode kontrasepsi yang paling banyak digunakan adalah metode suntik yaitu 47,96%. Di Desa Humbia Kecamatan Tagulandang Selatan Kabupaten SITARO, terdapat 41 orang yang menggunakan kontrasepsi suntik dari 78 akseptor KB. Kontrasepsi suntik merupakan yang paling banyak digunakan oleh para akseptor KB karena aman, sederhana, efektif dan dapat dipakai pasca persalinan. Penelitian ini bertujuan untuk mengetahui hubungan antara umur, pengetahuan dan sikap dengan penggunaan alat kontrasepsi suntik pada akseptor KB di Desa Humbia Kecamatan Tagulandang Selatan Kabupaten SITARO. Penelitian ini adalah penelitian survei analitik dengan rancangan studi potong lintang. Teknik pengambilan sampel yaitu total populasi. Populasi dalam penelitian ini adalah seluruh wanita pasangan usia subur yang memakai alat kontrasepsi di Desa Humbia Kecamatan Tagulandang Selatan Kabupaten SITARO. Analisis data dilakukan dengan menggunakan uji Chi-Square dengan tingkat kepercayaan 95% (α = 0,05). Hasil uji statistik menunjukkan variabel yang berhubungan dengan penggunaan alat kontrasepsi suntik yaitu umur (p-value = 0,044) dan pengetahuan (p-value = 0,002). Sedangkan variabel yang tidak berhubungan dengan penggunaan alat kontrasepsi suntik adalah sikap (p-value = 0,517).Kata Kunci: Umur, Pengetahuan, Sikap, Penggunaan Alat Kontrasepsi Suntik.ABSTRACTFamily Planning Program is an effort to increase community awareness and participation through maturation of marriage age, birth arrangement, family resilience development, improvement of small family welfare, happy and prosperous. In Indonesia the most widely used method of contraception is the injection method that is 47,96%. In Humbia Village, South Tagulandang District of SITARO Regency, there were 41 people who used injectable contraceptives from 78 Family Planning acceptors. Injectable contraception is the most widely used by Family Planning acceptors because it’s safe, simple, effective and can be used postpartum. This study aims to determine the relationship between age, knowledge and attitude with the use of injectable contraceptives on family planning acceptors in Humbia Village, South Tagulandang District of SITARO Regency. This research is an analytic survey research with cross sectional study design. The sampling technique is total population. The population in this study were all women of fertile couples who used contraceptives in Humbia Village, South Tagulandang District of SITARO Regency. Data analysis was done by using Chi-Square test with 95% confidence level (α = 0,05). The result of statistical test shows that variables related to the use of injectable contraceptives are age (p-value = 0,044) and knowledge (p-value = 0,002). While variable that has not related to the use of injectable contraceptives is attitude (p-value = 0,517).Keywords: Age, Knowledge, Attitude, Use of Injectable Contraceptives

    Isolated tricuspid valve infective endocarditis - A report of 6 cases

    Get PDF
    Six cases of isolated tricuspid valve endocarditis in young women are described. Preceding genital sepsis was a predisposing factor in 4 patients. Cardiac signs are unusual at presentation, rendering the diagnosis difficult. Pleuropulmonary manifestations are the predominant findings, while overt signs of tricuspid insufficiency and right heart failure occur late in the disease. Staphylococcus aureus is the pathogen most commonly found and requires energetic treatment for a minimum of 4 weeks. The value of echocardiography in establishing an early diagnosis is stressed. Persistent sepsis constitutes a major indication for surgery.S Afr Med J 1990; 78: 34-3

    A two-species continuum model for aeolian sand ripples

    Get PDF
    We formulate a continuum model for aeolian sand ripples consisting of two species of grains: a lower layer of relatively immobile clusters, with an upper layer of highly mobile grains moving on top. We predict analytically the ripple wavelength, initial ripple growth rate and threshold saltation flux for ripple formation. Numerical simulations show the evolution of realistic ripple profiles from initial surface roughness via ripple growth and merger.Comment: 9 pages, 3 figure
