"ABSTRAKPemeriksaan thyroid-stimulating hormon TSH) merupakan salah satu pemeriksaan utama dalam mendiagnosis kelainan pada kelenjar tiroid. World Health Organization (WHO) merekomendasikan pemeriksaan kadar TSH menggunakan bahan serum. Penggunaan plasma dapat membantu pencapaian turn around time (TAT) laboratorium namun perbedaan hasil pengukuran antara serum dan plasma belum diketahui. Pada penelitian dibandingkan hasil pengukuran kadar TSH menggunakan tabung penampung serum dengan clot activator tanpa gel pemisah (Tabung I), tabung penampung plasma dengan antikoagulan heparin tanpa gel pemisah (Tabung II), dan tabung penampung plasma dengan antikoagulan heparin dan gel pemisah (Tabung III). Selain itu juga dilihat gambaran kadar TSH berdasarkan jenis kelamin, usia, dan kadar glukosa darah sewaktu. Desain penelitian adalah potong lintang dengan menggunakan 89 subjek penelitian yang dipilih secara censecutive sampling. Didapatkan median kadar TSH pada tabung I, II, dan III secara berturut-turut sebesar 1,380 (0,032-7,420) µIU/mL, 1,380 (0,030-7,480) µIU/mL, dan 1,360 (0,030-7,460) µIU/mL. Tidak didapatkan perbedaan bermakna kadar TSH ketiga tabung secara statistik. Median selisih kadar TSH antara tabung II dan III dengan tabung I secara proporsional didapatkan sebesar -0,9% (-7,2 - 2,2)% dan -1,7% (-8,0 - 1,6)%. Penyimpangan kadar TSH tabung II dan III yang didapatkan telah sesuai dengan nilai ketidaktepatan yang dapat diterima menurut Ricos. Didapatkan gambaran median kadar TSH pada kelompok laki-laki dan perempuan secara berturut-turut sebesar 1,500 (0,032-4,250) µIU/mL dan 1,345 (0,058-7,420) µIU/mL. Median kadar TSH pada kelompok usia 31-40 tahun dan >61 tahun secara berturut-turut sebesar 1,190 (0,609-3,240) µIU/mL dan 1,730 (0,088-5,760) µIU/mL. Pada kelompok glukosa darah sewaktu <200 mg/dL didapatkan nilai median glukosa darah sewaktu pada kelompok kadar TSH di atas nilai rujukan, dalam rentang nilai rujukan dan dibawah nilai rujukan secara berturut-turut sebesar 175 (151-199) mg/dL, 89 (60-190) mg/dL, dan 107 (73-117) mg/dL. Dari hasil yang diperoleh dapat disimpulkan bahwa spesimen dari ketiga tabung penampung dapat digunakan untuk pemeriksaan kadar TSH tanpa memberikan perbedaan hasil yang bermakna baik secara statistik maupun secara klinis. Gambaran kadar TSH yang didapatkan menunjukkan nilai median kadar TSH lebih tinggi pada laki-laki dibandingkan perempuan, terdapat pola peningkatan kadar TSH pada kelompok usia yang lebih tua, dan nilai median glukosa lebih tinggi pada kelompok kadar TSH di atas rentang nilai rujukan.

ABSTRACTThyroid-stimulating hormone (TSH) is one of the important laboratory parameters in diagnosing the thyroid gland abnormalities. The World Health Organization (WHO) recommends using serum samples to measure TSH levels. The use of plasma samples can help to improve laboratory turn around time (TAT) but the difference of measurements results between serum and plasma samples is unknown. The aims of this atudy were to compare TSH levels using serum tubes with clot activator (Tube I), plasma tubes with heparin anticoagulants (Tube II), and plasma tubes with heparin anticoagulant and gel separator (Tube III), and to show an overview of TSH levels according to gender, age, and random blood glucose levels. A cross sectional study was conducted using 89 blood samples from subjects that were selected by consecutive sampling. The median TSH levels in tubes I, II, and III were 1.380 (0.032-7.420) µIU/mL, 1.380 (0.030-7.480) µIU/mL, and 1.360 (0.030-7.460) µIU/mL respectively. There were no statistically significant differences in TSH levels of the three tubes. The median TSH levels differences of tubes II and III compared to tube I were -0.9% (-7.2 - 2.2) and -1.7% (-8.0 - 1.6) respectively. Biases of the measurement results obtained were in accordance with the spesicified desirable bias according to Ricos. The median TSH levels of the male and female groups was 1.500 (0.032-4.250) µIU/mL and 1.345 (0.058-7.420) µIU/mL respectively. Median TSH levels of 31-40 years old age group and >61 years old age group were 1.190 (0.609-3.240) µIU/mL and 1.730 (0.088-5.760) µIU/mL respectively. In the group of blood glucose level <200 mg/dL, the median of blood glucose level according to above, within, and below reference range of TSH were 175 (151-199) mg/dL, 89 (60-190) mg/dL, and 107 (73-117) mg/dL. In conclusion, specimens from the three tubes could be used to examine TSH levels without giving neither statistically nor clinically significant difference. The measurement of TSH levels obtained in the study showed a higher median TSH levelin the male group compared to the female group, higher TSH levels in the older age group, and a higher median glucose level in the TSH group above the reference range of TSH.

"Nuclear medicine is an important element of daily practice for the endocrinologist, both for diagnosis and for treatment. The continuous rapid development of nuclear medicine procedures has created the need for a concise, up-to-date practical guide that presents the essential information required by the endocrinologist. This book is designed to ensure ease of use in clinical practice and provides the most relevant information on nuclear medicine as applied to endocrine pathology. It is divided into three sections covering general aspects of nuclear medicine, the role of nuclear endocrinology in diagnosis, and the role of nuclear endocrinology in therapy. The endocrine glands are covered by organ and by pathology. Pertinent background information is provided, choice of radiopharmaceutical is explained, and the role of different image acquisition techniques is discussed. In addition, informative clinical cases are presented with the aid of high-quality images."

"Concurrently, there have been a number of recent advances in surgical treatment, as well as diagnostic modalities that allow us to detect small amounts of residual local and metastatic disease. Additionally, a reexamination of past treatment regimens has led to new recommendations regarding the use of radioactive iodine, and to new therapeutic options, such as targeted therapy which have supplanted the use of more toxic chemotherapy for metastatic cancer. Multiple academic organizations have developed consensus guidelines for the management of thyroid cancer, occasionally with conflicting recommendations. In Thyroid cancer, a renowned group of authors presents a broad overview of the pathology, pathophysiology, diagnosis, and management of thyroid cancer, with an emphasis on recent evidence-based information.

"Keganasan tiroid dapat ditemukan sekitar 5% dari kasus dengan nodul tiroid. Untuk penatalaksanaan kasus nodul tiroid perlu membedakan kasus jinak dari yang ganas. Biopsi aspirasi jarum halus (BAJaH) dilakukan praoperasi sedangkan potong beku dilakukan pada saat operasi. Tujuan tulisan ini ialah mengevaluasi ketepatan diagnosis pemeriksaan BAJaH serta PB bersama sitologi imprint (PB+I) pada kasus-kasus nodul tiroid di Departemen Patologi Anatomik FKUI-RSCM. Penelitian ini merupakan uji diagnostik menggunakan data arsip klinikopatologik di Departemen Patologi Anatmik FKUI-RSCM selama tahun 1999-2003. Spesimen dengan kelengkapan data hasil pemeriksaan BAJaH; data hasil pemeriksaan potong beku disertai sediaan sitologi imprint, serta sediaan histologik terfiksasi formalin dari bahan biopsi / operasi tiroid yang sama, digunakan dalam penelitian ini. Sensitivitas, spesifisitas dan akurasi PB+I lebih tinggi daripada BAJaH (berturut-turut 86,8% vs 73,7% ; 99,0% vs 83,9% ; 94,8% vs 80,5%). Bila hasil BAJaH konkordan dengan hasil PB+I, akurasi gabungan ke dua pemeriksaan tersebut menjadi 95,1%. Evaluasi potong beku bersama sitologi imprint masih sangat bermanfaat, karena pemeriksaan ini secara bermakna menunjukkan akurasi yang tinggi dalam mendiagnosis keganasan tiroid.

Thyroid malignancy can be found on 5% of thyroid nodules. In order to better managed of thyroid nodules, skills to differentiate benign from malignant cases were needed. Fine needle aspiration biopsy (FNAB) was done preoperatively while frozen section (FS) and imprint cytology (IC) should be done intra-operatively. The objective of this research paper is to evaluate the diagnostic accuracy of FNAB versus frozen section combined with imprint cytology (FS+IC) in thyroid nodules at the Anatomic-Pathology Department FMUI-CM Hospital, Jakarta. This diagnostic test, used data from clinico-pathological records in Anatomic Pathology Department, Faculty of Medicine University of Indonesia / Dr. Cipto Mangunkusumo General Hospital, Jakarta, Indonesia during 1999-2003. Specimens with complete data of FNAB results, data of FS and slides of IC. All formalin fixed`specimens were reevaluated and used as the golden standard. Sensitivity, spesificity and accuracy of FS+IC were higher than FNAB (86.8% vs 73.7% ; 99.0% vs 83.9% ; 94.8% vs 80.5% respectively). If the results of FNAB were concordant with the result of FS+IC, the combined examination yields accuracy of 95.1%. The evaluation of frozen section combined with imprint cytology is very useful, because this examination significantly showed high accuracy in diagnosing thyroid malignancy.

"Latar belakang dan tujuan : Nodul tiroid banyak ditemukan pada populasi dewasa. Kebanyakan merupakan lesi jinak yang tidak memerlukan tindakan lanjutan, namun 7-15% dapat ganas. Modalitas paling sensitif untuk evaluasi adalah ultrasonografi (USG), namun untuk memastikan jenis nodul tetap diperlukan diagnosis invasif dengan lini pertama yaitu pemeriksaan sitopatologi dengan fine needle aspiration biopsy (FNAB). Saat ini berkembang elastografi untuk menilai kekakuan jaringan, dengan teori semakin ganas nodul maka semakin padat jaringan dan elastisitas berkurang. Elastografi kualitatif menggunakan skoring dengan kriteria Rago berdasarkan warna nodul yang semakin gelap dengan meningkatnya kepadatan. Diharapkan elastografi dapat menjadi tambahan untuk evaluasi nodul tiroid. Tujuan penelitian untuk mengetahui kesesuaian antara pemeriksaan strain elastografi kualitatif kriteria Rago dengan hasil sitopatologi. Metode : Uji kesesuaian menggunakan data primer elastografi nodul tiroid berdasarkan sistem skoring Rago dengan hasil sitopatologi berdasarkan klasifikasi Bethesda, dengan desain potong lintang (cross sectional), di RSCM bulan Juli-Agustus 2018. Subjek penelitian adalah 39 nodul yang dikategorikan menjadi benign, intermediate, dan malignant. Analisis statistik menggunakan uji McNemar dan Kappa. Hasil : Didapatkan kesesuaian antara hasil strain elastografi dengan FNAB dengan hasil McNemar test p=0,214, nilai Kappa R=0,52 dan p=0,000. Kesimpulan : Terdapat kesesuaian antara elastografi menggunakan sistem skoring kategori Rago dengan sitopatologi dengan tingkat kesesuaian moderate sehingga elastografi dapat menjadi pemeriksaan tambahan untuk evaluasi nodul tiroid.

Introduction : Thyroid nodule is common condition in adult populations, which mostly are benign. Nevertheless, malignancy can be found in 7-15% nodules. The most sensitive modality to evaluate thyroid nodule is ultrasonography (USG), although invasive examination is still necessary to confirm benignity or malignancy with first line is cytopathology with fine needle aspiration biopsy (FNAB). Elastography is developed to asses tissue elasticity, with theory that higher malignancy the cells are denser and elasticity is decreasing. In qualitative elastography there is Rago scoring system criteria based on colors appearing in nodules which darker as nodule grows denser. Elastography may become additional examination to evaluate thyroid nodules. The objective of this research is to acknowledge the concordance between qualitative strain elastography and cytopathology result.

Methods : This research is suitability test using primary data of thyroid nodules elastography and cytopathology results in RSCM between July to August 2018. The design is cross sectional. The subjects are 39 nodules and every nodule is grouped into three categories which is benign, intermediate, and malignant. Statistical analysis is performed using McNemar and Kappa test.

Result : Concordance can be found between scoring system strain elastography with FNAB results with McNemar test p=0,214, Kappa R=0,52 and p=0,000.

Conclusion : There is concordance between scoring system strain elastography using Rago criteria with FNAB results with moderate level of agreement. Thus, elastography can be used as additional examination to evaluate thyroid nodules."

Background: Melasma is an acquired hyperpigmentation disorder, clinically as

asymmetrical blackish brown macules, especially on the facial area. Several factors are

thought to play a role, including thyroid dysfunction and zinc deficiency.

Objective: To determine serum zinc levels in melasma and non-melasma patients with

and without thyroid dysfunction.

Methods: A cross-sectional study was conducted in Jakarta in September-December

2019. There were 60 melasma patients and 60 non-melasma patients. The two groups

were matched for age and sex. Atomic absorption spectrophotometry was used to

measure serum zinc levels. Blood laboratory was used to check thyroid function (TSH

and FT4). Statistical analysis was done by SPSS software.

Results: The mean serum zinc level in the melasma group was 10.25 ± 1.89 μmol / L

and non-melasma was 10.29 ± 1.46 μmol / L (p <0.901). The mean serum zinc level in

melasma patients with thyroid dysfunction was 8.77 ± 0.69, melasma without thyroid

dysfunction 10.33 ± 1.89, non-melasma with thyroid dysfunction 10.48 ± 2.4, and nonmelasma

without thyroid dysfunction 10.27 ± 1.4 (p <0.184).

Conclusions: There was no significant difference between serum zinc levels in the

melasma and non-melasma groups with and without thyroid dysfunction."
