PERBEDAAN GAMBARAN HISTOPATOLOGI OTOT JANTUNG TIKUS WISTAR AKIBAT PAPARAN ARUS LISTRIK MELALUI MEDIA AIR TAWAR DAN AIR LAU

Latar belakang: Listrik merupakan suatu bentuk energi yang pada keadaan tertentu dapat melukai tubuh bahkan dapat menyebabkan kematian. Sengatan arus listrik dapat menjalar melalui media air. Komplikasi trauma listrik salah satunya adalah serangan jantung. Sengatan listrik mengakibatkan gangguan pada kelistrikan jantung dan merusak otot jantung. Tujuan: Mengetahui perbedaan gambaran histopatologi otot jantung tikus Wistar akibat paparan arus listrik melalui media air tawar dan air laut. Metode:Penelitian ini merupakan penelitian eksperimental laboratorik dengan rancangan penelitian the post test only group design. Terdapat 2 kelompok perlakuan dimana setiap kelompok terdapat 6 tikus Wistar jantan. Setiap kelompok perlakuan diberi sengatan pada arus listrik bolak-balik, 220V, 200mA, 50Hz selama 60 detik melalui media air laut. Setelah diberi perlakuan, dilakukan dekapitasi pada leher tikus dan diambil organ jantung kemudian dilakukan pembuatan preparat histologi menggunakan pengecatan HE. Setiap sediaan preparat sampel jantung dilakukan pembacaan dalam lima lapangan pandang dengan pembesaran 400x.Sasaran pembacaan adalah inti sel pada otot jantung yang berbentuk persegi. Hasil:UjiIndependent-t test didapatkanhasilp=<0,001, karenap< 0.05 makaterdapat perbedaan bermakna antara kelompok perlakuan 1 dan kelompok perlakuan 2. Simpulan: Terdapat perbedaan bermakna antara kerusakan sel otot jantung tikus Wistar akibat paparan arus listrik melalui media air laut dan air tawar. Kata kunci: Paparan arus listrik, Gambaran histopatologi otot jantung, Air tawar, Air laut

GIANT NON-FUNCTIONING ADRENOCORTICAL CARCINOMA

Objective: This study aims to report a case of a 51 year old male who was referred to our Department of Urology and was diagnosed with a nonfunctioning giant ACC. Case(s) Presentation: The case report describes a 51-year-old Indonesian man who presented to our department with complaints of persistent upper left abdomen discomfort, previously misdiagnosed as dyspepsia. He was diagnosed as having non-functioning adrenocortical carcinoma and underwent open adrenalectomy. Discussion: Although the patient is 51 years old and the tumor has grown to a signify cant size, no lymph node involvement or metastases was found and resection margins were found to be negative. In our patient, functional adrenal work-up results were normal. This has led us to suspect a non-functioning adrenal tumor. Metastatic work-up with CT cranial, chest, and bone survey were performed, with negative result. The biopsy result after resection confirmed the diagnosis of ACC. Conclusion: ACC is a rare aggressive tumor, malignant with poor prognosis. In our case, the non-secretory mass was diagnosed late by manifestation of mass effect symptoms in the upper left quadrant of the abdomen and was previously misdiagnosed as symptoms of dyspepsia. The functional work-up of adrenal masses helped in the determination of its non-functional status. Early diagnosis of ACC and early surgical excision helps in improving the overall survival rate of the patient. Keywords: Non-functioning, adrenocortical carcinoma (ACC), adrenalectomy, case report
