Introduksi Spondilitis tuberculosis (TB) merupakan kasus infeksi tulang belakang tersering terutama di negara berkembang. Tiga hingga 5% kasus Spondilitis TB berkembang menjadi deformitas kifosis >60 derajat. Deformitas kifosis dapat mengakibatkan paraplegia dan gangguan fungsi lainnya, sehingga harus ditatalaksana dan dicegah dengan koreksi operatif. Studi ini bertujuan untuk mengetahui luaran klinis dan radiologis pada deformitas kifosis pasca koreksi operatif dan hubungannya dengan faktor-faktor yang memengaruhi deformitas kifosis. Metode Penelitian ini menggunakan desain potong lintang terhadap pasien Spondilitis TB dengan deformitas kifosis yang dilakukan tindakan koreksi operatif selama tahun 2014-2018 di RSUPN Cipto Mangunkusumo. Dilakukan penilaian luaran klinis ODI (Oswestry Disability Index) dan ASIA Impairment Scale, serta penilaian radiologis berupa persentase derajat koreksi dan loss of correction. Penilaian tersebut dilakukan pada saat pra-operasi, pasca-operasi, 6 dan 12 bulan pasca operasi, serta saat kontrol terakhir. Hasil Dari 78 pasien yang diikut sertakan dalam penelitian ini, rata-rata berusia 31,4 tahun dan mayoritas perempuan. Gejala awal tersering adalah backpain. Median jumlah keterlibatan vertebra adalah 2 dengan lokasi tersering pada level torakal. Durasi kontrol adalah 6 hingga 54 bulan. Pemilihan teknik operasi posterior lebih sering digunakan dibanding kombinasi dan tidak terdapat perbedaan yang bermakna pada pemilihan teknik operasi dengan luaran klinis maupun radiologis (p>0,05). Terdapat perbedaan yang bermakna secara statistik pada perbandingan nilai klinis, dan radiologis pre dengan pasca operasi (p<0,001). Perbaikan neurologis ASIA scale tampak mulai signifikan sejak 6 bulan pasca operasi (p<0,001). Sudut kifosis awal memberikan pengaruh yang signifikan terhadap semua kategori luaran (p<0,001). Terdapat komplikasi berupa pseudoarthrosis pada 2 pasien dan defisit neurologis yang menetap pada 1 pasien. Kesimpulan Tatalaksana operasi korektif pada pasien spondilitis TB dengan deformitas kifosis menunjukkan perbaikan luaran klinis, laboratorium dan radiologis. Sudut awal kifosis mempengaruhi luaran klinis dan radiologis.

ABSTRACT
Introduction Spondylitis tuberculosis (TB) is the most common case of spinal infection, especially in developing countries. Three to 5 % of Spondylitis TB cases will develop into more than 60o of kyphotic deformity. Kyphotic deformity can cause late paraplegia and other functional disturbances, therefore a kyphotic correction should be performed to prevent and treat the complications. The purpose of the study is to analyze the clinical and radiological outcome of kyphotic deformity in Spondylitis TB patients post kyphotic correction and to analyze the factors influencing the kyphotic deformity Method This study used cross-sectional design on Spondylitis TB patients who underwent corrective surgery as one of the treatment during 2014-2018 at Cipto Mangunkusumo Hospital. Evaluation of delta ODI (Oswestry Disability Index) and ASIA impairment scale were used to assess the clinical outcome. For radiological outcome, we assessed the percentage of correction and loss of correction. The data was collected from the medical record and also the patient; pre-surgery, post-surgery, 6 and 12 months post-surgery, also the current condition Result Out of the 78 patients included in this study, the average age was 31.4 years and for the majority of women. The majority of initial symptoms was complaint of backpain. The median number of vertebral involvement was 2, the majority of the location of the vertebrae involved were at the thoracic level. The choice of posterior surgery techniques is more often used than combination (posterior-anterior), however no significant differences was found when we compared the technique used with the clinical and radiological outcome (p>0,005) There were significant differences between pre and post-operative clinical and radiological value (p<0,001). Neurological improvement (ASIA scale) appears to be significant since 6 months postoperatively (p <0.001). Pre-operative kyphotic angle was found to be an influential factor in all outcome categories (p<0,001). There was pseudoarthrosis in 2 patients and refracter neurological deficit in 1 patient.

Sebagian besar peneliti menyatakan pasien dengan clubfoot idiopatik yang ditatalaksana dengan metode Ponseti memberikan hasil baik. Kekurangan metode Ponseti adalah angka rekurensi yang relatif tinggi. Penelitian ini merupakan penelitian kohort retrospektif yang dilakukan di Poliklinik Orthopaedi Rumah Sakit Ciptomangunkusumo pada tahun 2007 - 2010. Studi ini menunjukkan hanya variabel wilayah tempat tinggal yang mempengaruhi luaran skor Pirani dengan nilai OR 21,60 (95% IK 2,39 – 195,29). Jarak yang jauh dari tempat penyedia fasilitas kesehatan, membuat orang tua pasien mengalami keberatan untuk kontrol rutin. Hal tersebut menyebabkan penatalaksanaan yang tidak optimal sehingga menyebabkan hasil akhir yang kurang baik. Jarak tempat tinggal terhadap tempat layanan kesehatan, berpengaruh terhadap luaran penatalaksanaan Ponseti pada kasus clubfoot di RSCM.

ABSTRACT
Most of the researchers said that patients with idiopathic clubfoot treated by the Ponseti method give good results. However, this method has the disadvantage which is a relatively high recurrence rate which influenced by cultural factors. The study design is retrospective cohort study conducted at the outpatient setting in Ciptomangunkusumo Hospital from 2007 to 2010. This study showed that only the residential distance to the health facility that influence the value of Pirani score outcome OR 21.60 (95% CI 2.39 to 195.29). Patients living far from health facility, tend to miss routine control. This leads to sub-optimal management causing unfavorable outcome. The residential distance to the health service, influence the outcome of the Ponseti treatment of clubfoot cases in the hospital.

Introduction Osteosarcoma is the most common malignant bone tumor seen in Cipto Mangunkusumo Hospital (CMH). Treatment for osteosarcoma includes limb-salvage surgery (LSS), and it is increasingly more frequently performed compared to amputation. This study aims to analyze the outcome of LSS compared to amputation for osteosarcoma patients in CMH. Methods This is a retrospective cohort study to review osteosarcoma patients during 1995-2014 period in CMH. Analysis was performed on survival rate, local recurrence, metastasis, complication, and functional score according to Musculoskeletal Tumor Scoring System (MSTS) for patients underwent LSS or amputation. Kaplan-Meier method was used to determine survival rate, and disease-free survival rate between LSS and amputation. Log-rank analysis was used to determine relationship between patients characteristic. Chi-Square, Exact-Fischer, and Mann-Whitney U tests were used to analyze the correlation between MSTS score and patient characteristics, rate of recurrence, metastasis, and complication. To determine the influence of patient characteristics to survival, Cox regression analysis, Wald Test and backward stepwise multivariate analysis were performed. Results and discussion 5-year survival rate osteosarcoma patients was 14.6%, 5-year survival rate for LSS was 34.8% compared to 15.9% for amputation. Disease-free survival for LSS was 96,2%, while amputation was 86,5%. Survival were influenced by metastasis, type of surgical intervention, and tumor size. According to multivariate analysis, survival was most influenced by metastasis. Metastasis were found predominantly in lungs. Initial symptoms and Enneking stage were correlated to metastasis (p=0.02 and 0.007, respectively). Infection was the most common complication. FNAB gave the least complication compared to other types of biopsy. LSS gave the highest functional score (83.3%) compared to amputation (61.7%). Patients with local recurrence tend to have poor functional score (p=0.023). Conclusion The highest survival rate for osteosarcoma patients in CMH was found on patients who underwent LSS. Good functional outcome according to MSTS score (83.3%) were found on patients who underwent LSS and free of local recurrence.

Psoriasis merupakan penyakit autoimun yang disebabkan kelainan genetik dan dipicu faktor lingkungan, penyakit ini menyerang kulit dan sistemik seperti sendi dan kuku. Sel punca mesenkim (SPM) asal tali pusat manusia memiliki kapasitas proliferasi yang tinggi, imunomodulator yang luas dan imunogenitas yang rendah. Penelitian ini menggunakan model tikus psoriasis yang diinduksi dengan krim imiquimod 5% selama 6 hari. Tikus dibagi menjadi kelompok 5 kelompok yang diberi SPM atau Phosphate Nuffer Saline (PBS) secara intradermal atau subkutan serta kontrol normal. Pemberian SPM dan PBS dilakukan sebelum pengolesan krim. Penilaian harian kulit tikus dilakukan dengan skoring modified Psoriasis Area and Severity Index (mPASI). Setelah pembedahan, kulit tikus dianalisa terhadap ekspresi relatif gen Interleukin (IL)-17 dan IL-10. Sebagian kulit difiksasi dengan formalin dan dilakukan pemeriksaan histologi dan imunohistokimia dengan antibodi Anti-CD11b. Analisa statistik memperlihatkan skor mPASI kelompok SPM mengalami penurunan bermakna dibanding kelompok PBS. Ekspresi relatif gen IL-17 menurun dan gen IL-10 meningkat pada kelompok SPM dibandingkan PBS. Pewarnaan Hematoksilin dan Eosin memperlihatkan rerata tebal epidermis dan jumlah kapiler mengalami penurunan pada kelompok SPM dibanding PBS. Rerata jumlah infiltrasi sel CD11b+ kelompok SPM menurun secara bermakna dibandingkan PBS. Penyuntikan SPM terutama intradermal mampu menyebabkan remisi pada lesi lokal kulit psoriasis pada model tikus Wistar. ......Psoriasis is a chronic inflammatory disease affecting mainly the skin and other parts such as nails and joints. Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) are highly proliferative immunomodulator cells with low immunogenicity. The Psoriasis rat model was induced with 5% imiquimod cream for 6 days. The rats were divided into 5 groups receiving intradermal or subcutaneous injections of hUC-MSCs or Phosphate Buffer Saline (PBS), and a normal control group. MSCs and PBS were administered before cream application. Daily skin assessments were performed using a modified Psoriasis Area and Severity Index (mPASI) scoring system. After harvest, rat skin was analyzed for relative expression of Interleukin (IL)-17 and IL-10 genes. Some skin samples were fixed with formalin for histological examination and immunohistochemistry with Anti-CD11b antibodies. Statistical analysis showed a significant reduction in mPASI scores in the hUC-MSCs group compared to the PBS group. Histology staining revealed a decrease in epidermal thickness and capillary in the hUC-MSCs group. The infiltration of CD11b+ cells significantly decreased in the hUC-MSCs group.  The relative gen expression of IL-17 decreased, while IL-10 gene increased in the hUC-MSCs group. Particularly, intradermal injection of hUC-MSCs induced remission of local psoriasis skin lesions in the rat model.
