Objective: To evaluate and compare the costal cartilage lateral crural strut graft’s (LCSG) ability to support a weak lateral crus in patients with external nasal valve dysfunction (EVD) undergoing primary versus revision functional rhinoplasty. Methods: This is a prospective cohort study of 26 patients (mean [SD]: 40.23 [6.75] years of age; 10 [38%] females) with clinically diagnosed EVD, who underwent primary versus revision functional rhinoplasty with the use of a costal cartilage LCSG (10 [38%] primary functional rhinoplasty patients and the 16 [62%] revision patients). Preoperative and 12-month postoperative subjective and objective functional measurements along with statistical analysis were performed. Results: While all baseline demographic and preoperative functional measurement scores were similar between the 2 groups, the primary cohort’s preoperative scores were higher overall. Follow-up was a mean of 14.58 months. The primary group demonstrated a greater difference in score improvement postoperatively in all categories. All patients had significantly improved visual analog scale (VAS), Nasal Obstruction Symptom Evaluation Scale, 22-Item Sinonasal Outcome Test, and nasal peak inspiratory flow (NPIF) scores. When comparing the overall score outcome and surgical efficacy of the LCSG, both groups had near equal final score outcomes with the exception of VASL and NPIF. Conclusion: The LCSG is a viable and versatile option in the management of EVD for both primary and revision rhinoplasty patients.

"The aim of this work is to evaluate the shelf life of cow’s ricotta under MAP (Modified Atmosphere Packaging). MAP is a packaging technique commonly used in the food industry in order to control the microbial growth. After the extraction of the air present in the headspace of the package, a mixture of CO2, O2 and N2 in different percentage is usually introduced before the packaging sealing. Based on these premises, a design of experimental tests has been created in order to evaluate the effect of each process parameters. To perform these test, it is also required the creation of thermoformed trays (made with a multilayer material using PET/EVOH/PE) in which the ricotta was inserted and packaged in a modified atmosphere. After the time intervals established in the experimental program, the analysis of the MAP was carried out using a special instrument (“Oxybaby” made by Witt SpA), able to measure the quantity of gas present in the headspace of the thermoformed trays. Then a statistical analysis of the obtained results was carried out. The results showed that after 10 days the product was edible for all types of atmosphere, but at 20 and, especially, at 30 days, even in the trays wrapped with CO2, the product was not acceptable for human consumption. One of the possible solutions, in order to lengthen the shelf life of cow’s ricotta, consists in the pre-sterilization of the trays before the product packaging with a solution of H2O2."

St George's Respiratory Questionnaire

Tuberculosis (TB) is one of the disease as the highest contributor to the disease burden in Indonesia. Tuberculosis can affect the patients’ quality of life, such as psychological, physical, and social functioning. St. George's Respiratory Questionnaire (SGRQ) is a special instrument which was widely used to measure the patients’ quality of life with respiratory disease. The objective of this study was to validate the Indonesian version of the SGRQ as instrument to collect data. A descriptive cross section design with 61 subjects was conducted at the Pulmonary Clinics and Primary Health Centers in the region of Yogyakarta within 3 months. The validation process included the known group validity, convergent and discriminant validity and factor analysis. There were 14 items question numbers which did not meet the criteria for convergent validity and 9 items which did not meet the criteria for discriminant validity. Known group validity analysis on gender showed that of the three domains of SGRQ, the activity domain gave statistically significant result. The factor analysis showed the result of Kaiser Meyer Olkin analysis (KMO) was less than 0.5. With a few modifications, the Indonesian version of SGRQ is valid and reliable for measuring quality of life in tuberculosis patients.

Anak penderita Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) di Indonesia memperlihatkan tren yang semakin meningkat karena meningkatnya proporsi perempuan terinfeksi HIV/AIDS. Pertimbangan pada dampak besar yang dihadapi anak penderita HIV mendorong kebutuhan pengembangan instrumen khusus untuk mengukur kualitas hidup mereka. Penelitian ini bertujuan mengembangkan instrumen kualitas hidup anak penderita AIDS dengan memodifikasi instrumenyang ada sesuai dengan konteks Indonesia. Pada penelitian ini ditemukan hasil bahwa instrumen yang dikembangkan mempunyai reliabilitas yang cukup baik pada balita dan anak usia 5 – 11 tahun. Nilai reliabilitas (Cronbach’s Alpha) balita, domain fungsi fisik, fungsi sosial, dan gejala HIV masing masing adalah 0,71; 0,72; dan 0,88, sedangkan pada anak 5 – 11 tahun, domain fungsi-fungsi fisik, psikologis, sosial, sekolah, dan gejala terkait HIV masing-masing 0,76; 0,89; 0,67; 0,67; dan 0,88. Penelitian ini menunjukkan untuk konteks Indonesia, nilai ambang batas CD4 yang menunjukkan perbedaan kualitas hidup adalah 15%. Pada balita, dari berbagai ketiga domain, hanya domain gejala terkait HIV yang cukup sensitif untuk mendeteksi perbedaan kualitas hidup anak, sementara pada anak 5 – 11 hanya domain fungsi fisik dan fungsi psikologis yang cukup sensitif untuk mendeteksi perbedaan kualitas hidup anak. Penelitian ini menunjukkan bahwa dampak HIV pada anak masih terkonsentrasi pada gangguan fungsi fisik, fungsi psikologis, dan gejala terkait HIV.Kata kunci: Instrumen pengukuran, anak terinfeksi HIV, kualitas hidupAbstractChildren with HIV/AIDS in Indonesia are increasing due to the increase of woman with HIV. A special instrument for measuring quality of life (QoL) of children with HIV is needed to be developed as the great impact of the infection to children. This study was conducted by modifying the existing QoL instrument of children for Indonesian context. The study indicated that thereliability of the instrument is quite good both for children under 5 and 5 – 11 years old. Reliability values (Cronbach’s Alpha) for under 5, domains of physical function, social function, and HIV-related symptoms are 71, 72, and 88 respectively while for children 5 – 11 years old, domains of physical, psychological, social, and school functions, and HIV-related symptoms are 76, 89, 67, 67, and 88 respectively. The study showed, for Indonesian context, 15% of CD4 is indicated as the threshold to detect the difference of QoL forchildren with HIV. However, for under 5 years old, only questions of HIV-related symptoms domain which is sensitive to detect difference QoL, whereas for children of 5 – 11 years old, the questions concerning physical and psychological domains which are sensitive to detect difference QoL. The study indicated that the impact of HIV on children is mostly on physical andpsychological functions and HIV-related symptoms.Key words: Measurement instrument, children with HIV, quality of life
