Introduction The cochlear anatomy varies in each individual, and that has an impact on decisions regarding the insertion of electrodes. The measurement of the cochlear size is the routine examination required to choose the proper cochlear implant (CI) electrodes. Objective To acquire normative data on the size of the cochlea (length, width, height, scala timpani [ST] height, cochlear duct length [CDL]) of CI candidates in Medan, Indonesia. Methods This descriptive study was conducted based on high-resolution computed tomography (HRCT) temporal bone data and on HRCT temporal data manipulated to reconstruct three-dimensional (3D) multiplanar images with OsiriX MD DICOM Viewer version 9.5.1 (Pixmeo SARL, Bernex, Geneva, Switzerland) viewer of 18 patients (36 ears) who were CI candidates in Medan, Indonesia, in order to determine cochlear length (A), cochlear width, cochlear height, ST height and CDL, calculated through a simple mathematical function. Results The average cochlear length (A) was 8.75 mm (standard deviation [SD] = 0.31 mm); the average cochlear width was 6.53 mm (SD = 0.35 mm); the average cochlear height was 3.26 mm (SD = 0.24 mm) and the average ST height at the basal cochlea was 1.00 mm (SD = 0.1 mm); and 0.71 mm (SD = 0.1 mm) at the half turn of cochlea. The average total CDL was 32.45 mm (SD = 1.31 mm; range: 30.01–34.83 mm). Conclusion The cochlear size varies in each individual; therefore, the temporal bone measurement of CI candidates using HRCT is essential: for the selection of suitable implant electrodes; to minimize cochlear damages at the insertion of the electrode arrays; and to maximize the hearing improvements.

AbstrakTempat pembuangan akhir (TPA) sampah domestik dengan sistem penampungan terbuka sangat berisiko mencemari air tanah milik warga yang bermukim di sekitarnya melalui proses perlindian. Untuk mengetahui kandungan logam berat dalam air tanah di sekitar TPA, sebanyak 68 sampel air sumur gali (45 sumur Dusun I dan 23 sumur Dusun IV) dari Desa Namobintang Kecamatan Pancurbatu Kabupaten Deli Serdang, Sumatera Utara, telah dianalisis dengan inductively couple plasma atomic emission spectroscopy. Hubungan jarak sumur dengan konsentrasi kromium, merkuri, dan timbal diuji dengan Mann-Whitney, Spearman's Correlation dan analisis regresi linier sederhana. Hasil penelitian menunjukkan konsentrasi kromium, timbal, dan merkuri (rerata ± deviasi standar, mg/L) masing-masing 0,036 ± 0,0096; 0,0003 ± 0,00018; dan 0,005 ± 0,0041 (Dusun I); 0,0370 ± 0,0115; 0,00026 ± 0,00013; dan 0,0070 ± 0,0069 (Dusun IV). Dari 68 sumur yang dianalisis, hanya ada 8 sumur yang konsentrasi timbalnya melebihi batas menurut Peraturan Kementerian Kesehatan Republik Indonesia Nomor 492/Per/IV/2010. Sementara itu, tidak ada korelasi jarak sumur gali ke TPA dengan konsentrasi kromium, merkuri, dan timbal dalam air sumur gali tersebut. Disimpulkan bahwa perlindian sampah di Namobintang tidak mencemari air sumur-sumur gali yang berjarak 84 meter atau lebih dari TPA. Kata kunci: Kromium, merkuri, tempat pembuangan akhir (TPA), timbal Abstract Dumping site of domestic wastes has potential risk to contaminate groundwater of the surrounding population through leaching process. To determine heavy metals (chromium, lead, and mercury) in groundwater at surrounding dumping site, a total of 68 dig well water samples (45 from Hamlet I and 23 from Hamlet IV) of Namobintang Village, Pancurbatu Sub-District of Deli Serdang Regency, North Sumatra, were analyzed using Inductively Couple Plasma Atomic Emission Spectroscopy. The relationship between the dig well distance and chromium, mercury, and lead content was tested by Mann-Whitney, Spearman's Correlation and Simple Linier Regression. The result of this study showed that chromium, lead, and mercury concentrations (mean ± SD, mg/L) were 0.036 ± 0.0096; 0.0003 ± 0.00018; and 0.005 ± 0.0041 (Hamlet I); 0.0370 ± 0.0115; 0.00026 ± 0.00013; and 0.0070 ± 0.0069 (Hamlet IV). Of 68 dig well water samples analyzed, there were only 8 water samples that had lead concentrations exceeding the drinking water limit of Peraturan Kementerian Kesehatan Republik Indonesia Nomor 492/Per/IV/2010. Meanwhile, there was no correlation of dig well distance to dumping site and heavy metal concentrations in dig well water. The study concluded that solid waste leachate in Namobintang did not contaminate the dig wells water located at 84 meters or more from the dumping site.

Background: The use of toluene in printing dominates the use of metal chemicals. Toluene is used in 75% of printing work activities. Accumulation of toluene concentrations in printing can cause health problems to workers. The purpose of this study was to analyze the effect of toluene exposure on central nervous system disorders in printing industry workers. Subjects and Method: This study was cross sectional in the printing industry in Medan, North Sumatra. The population consists of 50 people with consecutive sampling technique sampling. Data on subjective symptoms of central nervous system disorders were measured by the German version of the Q18 questionnaire. The data were analyzed using multiple logistic regression tests. Results: Subjective symptoms of central nervous system disorders increased with tenure ≥2 years (OR = 4.19; p = 0.018) and smoking (OR = 8.91; p = 0.001). Subjective symptoms of central nervous system disorders decreased with age ≤30 years (OR = 0.17; p = 0.004), female sex (OR = 0.50; p = 0.002). Conclusions:The most dominant variable affecting the subjective symptoms of central nervous system disorders is the smoking habit variable with a probability value of 0.92 or 92%.

Background: Musculoskeletal complaints often occur in saleswomen who do awkward standing during work. Repair of standing position can reduce the risk of musculoskeletal pain. This study aimed to examine the effectiveness of corrective work posture on alleviating musculoskeletal disorder (MSD) symptoms among saleswomen in the department store. Subjects and Method: This was a quasi experiment before and after with no control design conducted in Rantauprapat department store, North Sumatera. A sample of 30 sales women from the department store was selected for this study. The dependent variable was MSD scores as measured by Nordic Body Map (NBM). The independent variables were corrective work posture. The data before and after corrective work posture were compared and tested by t-test. Results: There was a difference between poor and good posture in MSD symptoms among saleswomen in the Department Store. Saleswomen with poor posture had higher MSD symptoms (mean 64.45) than those with good posture (53.39), and it was statistically significant (p= 0.001). Conclusions: Saleswomen with poor posture has higher MSD symptoms than those with good posture.
