Each point is one tumor sample, which we have color-coded by tissue type. A dotted box highlights the cluster of samples that have both PIK3CA and TP53 mutations, which are usually mutually exclusive. (EPS 751 kb

    Penerapan biaya standar dapat mendorong para eksekutif dan penyelia Perusahaan untuk meningkatkan efisiensi dan efektifitas proses produksi untuk mencapai standar yang telah ditetapkan. Penetapan biaya standar dapat memberikan pedoman untuk mengetahui biaya yang seharusnya terjadi dalam proses produksi. Adapun tujuan dari penelitian ini adalah untuk mengetahui besar biaya standar yang telah diterapkan dan bagaimana penerapan biaya standar pada PT. Pertani. Alat analisis data yang digunakan adalah analisa metode deskriptif analisa dengan pendekatan kuantitatif. Dari hasil analisa tersebut Perusahaan sudah menerapkan biaya standar. Pada tahun 2011 besar biaya stadar yang telah diterapkan adalah sebesar Rp. 6.569.771.800 dengn biaya produksi yang terjadi Rp. 5.563.445.750 dengan demikian Perusahaan mengalami efisiensi sebesar Rp. 1.006.326.050 dengan presentase 18,088 %. Oleh karena itu sebaiknya Perusahaan mempertahankan biaya produksi yang telah disepakati dengan para pemasok sehingga efisiensi dapat tetap terjadi dikarenakan lebih murah dari standar harga yang telah ditetapkan oleh Perusahaan

    Perioperative lumbar drain utilization in transsphenoidal pituitary resection

    ObjectiveTo evaluate lumbar drain (LD) efficacy in transnasal resection of pituitary macroadenomas in preventing postoperative cerebrospinal fluid (CSF) leak, technique safety, and effect on length of hospital stay.MethodsWe conducted a retrospective data review of pituitary tumor patients in our institution who underwent surgery between December 2006 and January 2013. All patients were operated on for complete surgical resection of pituitary macroadenoma tumors. Patients were divided into 2 groups: group 1 received a preoperative drain, while LD was not preoperatively inserted in group 2. In cases of tumors with suprasellar extension with anticipation of high-flow leak, LD was inserted after the patient was intubated and in a lateral position. Lumbar drain was used for 48 hours, and the drain was removed if no leak was observed postoperatively. In documented postoperative CSF leak patients with no preoperative drain, the leak was treated by LD trial prior to surgical reconstruction. Cases in which leak occurred 6 months postoperatively were excluded.ResultsOur study population consisted of 186 patients, 99 women (53%) and 87 men (47%), with a mean age of 50.3+/-16.1 years. Complications occurred in 7 patients (13.7%) in group 1 versus 21 (15.5%) in group 2 (p=0.72). Postoperative CSF leak was observed in 1 patient (1.9%) in group 1 and 7 (5%) in group 2 (Fisher exact test=0.3). Length of hospital stay was a mean of 4.7+/-1.9 days in group 1 and a mean of 2.7+/-2.4 days in group 2 (p<001). The most common reason to extend hospital stay was management of diabetes insipidus.ConclusionAlthough LD insertion is generally considered safe with a low risk of complications, it increases the length of hospitalization. Minor complications include headaches and patient discomfort

    Meningiomas of the Tuberculum and Diaphragma Sellae

    Introduction Although tuberculum sellae (TS) and diaphragma sellae (DS) meningiomas have different anatomical origins, they are frequently discussed as a single entity. Here we review the radiologic and intraoperative findings of TS and DS meningiomas and propose a radiologic classification. Methods We retrospectively reviewed 10 consecutive TS and DS meningiomas. Data regarding clinical presentation, preoperative imaging, and intraoperative findings were analyzed. Three sellar dimensions were measured on magnetic resonance imaging (MRI): the tuberculum-sellar floor interval (TSFI), the planum-tuberculum interval (PTI), and the total height. Results Three distinct anatomical patterns were recognized: exclusively tubercular meningiomas (type A) were accompanied by elongation of the TSFI and, more significantly, of the PTI; combined TS and DS meningiomas (type B) were associated with relative elongation of both the PTI and TSFI; and the sole exclusively DS meningioma (type C) was associated with elongation of neither PTI nor TSFI. Conclusion Suprasellar meningiomas can be classified as tubercular, combined, or diaphragmatic based on preoperative MRI. Exclusively tubercular meningiomas (type A) require only a supradiaphragmatic approach. Tumor involvement of the sellar diaphragm (type B or C) requires resection of the diaphragm and thus a combined infra- and supradiaphragmatic approach
