BACKGROUND: Nasopharyngeal carcinoma (NPC) is malignant tumor growing in nasopharynx with a predilection in fossa Rossenmuller and nasopharyngeal roof. This research aimed to prove whether the means of argyrophilic nucleolar organizer region (mAgNOR) can predict the success of treatment in nasopharyngeal carcinoma patients.METHODS: We used diagnostic test method with longitudinal design and purposive sampling technique. Endoscopic biopsy examination was performed on 15 nasopharyngeal carcinoma patients before and after therapy, 13 patients underwent chemotherapy and other two underwent chemoradiotherapy. Tumor tissues were stained and AgNOR was calculated.RESULTS: Based on the tumor stage, sample characteristic showed 3 patients (20%) were in stage II, 3 patients (20%) in stage III, and 9 patients (60%) in stage IV, with pre- and post-therapy mAgNOR were 1.610±0.988 and 1.000±0.000, respectively in stage II, 1.100±0.092 and 1.000±0.000, respectively in stage III, 1.226±0.265 and 1.107±0.164, respectively in stage IV patients. Based on histopathology type, 4 patients (26.7%) had non keratinizing squamous cell carcinoma with pre- and post-therapy mAgNOR were 1.117±0.134 and 1.060±0.120, respectively, while 11 patients (73.3%) had undifferentiated squamous cell carcinoma with pre- and post-therapy mAgNOR were 1.335±0.528 and 1.065±0.146, respectively. Overall the pre-therapy were significantly higher than post-therapy mAgNOR. In subgroups there are significant differences in stage IV and type 3.CONCLUSION: The values of AgNOR were decreased in all NPC stages and significantly decreased in undifferentiated squamous cell carcinoma. AgNOR can be used to predict the successfulness of therapy in NPC.KEYWORDS: nasopharyngeal carcinoma, therapy, proliferation, mAgNOR
Latar belakang: Atresia koana adalah tertutupnya satu atau kedua posterior kavum nasi oleh membranabnormal atau tulang. Hal ini dapat terjadi bersamaan dengan kelainan kongenital lainnya. Atresia koanabilateral menyebabkan keadaan darurat pada saat kelahiran. Angka kejadian atresia koana adalah 1 kasus per5000 - 8000 kelahiran. Kejadian pada perempuan dua kali lebih banyak daripada laki-laki. Tujuan: Membahassatu kasus bayi dengan atresia koana bilateral yang didiagnosis di ruang operasi, yang tidak terdeteksisebelumnya karena adanya meningosil. Kasus: Bayi perempuan 16 hari dengan meningosil dan atresia koanabilateral. Penatalaksanaan: Pasien menjalani koanoplasti transnasal dan pemasangan stent. Pasien sembuhdengan baik. Kesimpulan: Atresia koana dapat terjadi bersama dengan kelainan kongenital lainnya, sehinggamemerlukan pemeriksaan yang teliti karena atresia koana bilateral menyebabkan keadaan darurat danmemerlukan penanganan segera.Kata kunci : atresia koana, koanoplasti, stent.ABSTRACTBackground: Choanal atresia is a condition where one or both posterior nasal cavity is blocked byabnormal bony or soft tissue. This condition can occur concomitant with other congenital anomalies. Bilateralchoanal atresia causes emergency situation at birth. The incidence of choanal atresia is one case per 5000-8000births and are twice as much in females. Purpose: To discuss a case of bilateral choanal atresia which wasdiagnosed in the operating theatre, undetected previously because of the meningocele. Case: A baby girl 16 daysold with meningocele and bilateral choanal atresia. Management: The patient underwent transnasalchoanoplasty and stenting. The result was satisfactory. Conclusion: Choanal atresia can occure with othercongenital abnormalities, so careful examination is mandatory as bilateral choanal atresia needs promptmanagement.Keywords : choanal atresia, choanoplasty, stent
Latar belakang: Adenoma pleomorfik adalah tumor kelenjar saliva yang paling sering ditemukan, yang merupakan suatu tumor jinak campuran yang terdiri dari sel-sel epitel dan diferensiasi mesenkimal. Adenomapleomorfik (AP) paling banyak ditemukan pada kelenjar saliva minor yang terdapat pada palatum, kemudian bibir, dasar rongga mulut, lidah, tonsil, faring, daerah retromolar dan rongga hidung. Kasus adenoma pleomorfik pada tonsil sangat jarang ditemukan, insiden AP lebih sering pada wanita dibanding pria dan terjadi pada usia 40-60 tahun, paling banyak pada usia 43-46 tahun. Tujuan: Melaporkan satu kasus AP pada tonsil seorang bayi yangberumur 7 bulan yang dilakukan tindakan ekstirpasi tumor trans-oral. Kasus: Seorang bayi perempuan umur 7 bulan, berat 6 kg datang dengan keluhan utama mendengkur. Dari alloanamnesis (ibunya) riwayat mendengkur dialami sejak anak berusia 4 bulan, bunyi napas bertambah keras sejalan dengan bertambahnya umur. Pada usia 6bulan pasien mulai sesak napas terutama saat minum susu, kadang-kadang disertai regurgitasi saat minum susu, tidak ada riwayat demam, kejang dan influenza sebelumnya. Dari pemeriksaan fisis Telinga Hidung Tenggorok (THT) tidak ditemukan kelainan pada pemeriksaan otoskopi dan rinoskopi anterior. Pada pemeriksaan faringoskopiditemukan massa pada pole atas fossa tonsilaris, tonsil T1 di inferior dari massa. Tonsil kiri T1 tenang. Bayi ini didiagnosis tumor tonsil kanan. Penatalaksanaan: Dilakukan tindakan eksterpasi tumor pada rongga mulut. Hasil pemeriksaan histopatologik jaringan tumor setelah tindakan eksterpasi tumor trans oral adalah adenoma pleomorfik sesuai dengan gambaran makroskopis massa. Kesimpulan: Suatu kasus tumor kelenjar saliva, yang sangat jarang terjadi pada anak.Kata kunci : Adenoma pleomorfik, tumor kelenjar saliva, ekstirpasi tumor trans oral.
