HIV/AIDS has become a burden for health in with it sufferers has reached 39 million worldwide. Around 620 thousand PLWHA has been identified all over Indonesia, with Surabaya has been listed among the top five cities with the highest number of HIV / AIDS cases in Indonesia. This study was to determine the correlations between the HIV / AIDS knowledge with the Surabaya college studentâ€™s attitude towards PLWHA. This study was observational analytic research with cross-sectional approach. A proportional sampling chose as the research sampling technique, with 250 college students became the respondents. Data were collected from the results of filling out the online questionnaire. A Contingency Phi was used to perform a statistical test. The results indicated only 41.6% of respondents had a good knowledge level about HIV/AIDS, while 77% of the students have already shown a positive attitude towards PLWHA. Furthermore, it is known that there was a relationship between students' knowledge regarding HIV / AIDS and their attitude towards PLWHA with a p-value of 0,000. From these results, it is expected that there will be an HIV/AIDS socialization for college students to increase a more comprehensive knowledge about HIV/AIDS and PLWHA.

Published: October 2018

Pulau Sulawesi dipengaruhi oleh fenomena Central Pacific (CP) dan Eastern Pacific (EP) El Niño. Curah hujan Sulawesi mencakup ketiga pola hujan yang ada di Indonesia yaitu Monsunal, equatorial, dan lokal. Variabilitas ketiga pola curah hujan tersebut akan memberikan respon yang berbeda terhadap pengaruh dari kedua tipe El Niño tersebut. Maka, Kajian ini akan membahas pengaruh dari kedua tipe El Niño terhadap curah hujan Sulawesi. Penelitian ini Menggunakan data curah hujan bulanan berasal dari Climate Prediction Center (CPC) National Oceanic and Atmospheric Administration (NOAA), Suhu Permukaan Laut (SPL) bulanan dari System Ocean Data Assimilation (SODA) versi 2.2.4 dan oceanic Niño Indeks (ONI) dengan periode Januari 1950 hingga Desember 2010 (60 tahun). Perhitungan statistik sederhana berupa perata-rataan, korelasi, dan analisa komposit digunakan dalam kajian ini. Penentuan tipe El Niño menggunakan tiga buah indeks yang berbeda. Hasilnya diperoleh bahwa Curah hujan Sulawesi berkurang saat kedua tipe El Niño. Penurunan curah hujan akibat EP El Niño berkisar antara 5 – 20 mm sedangkan akibat CP El Niño berkisar antara 2-12 mm. Wilayah Sulawesi dengan pola curah hujan monsunal merupakan wilayah yang mengalami penurunan curah hujan terbesar akibat kedua tipe El Niño tersebut, kemudian diikuti dengan pola curah hujan equatorial dan terakhir Lokal.

The aim — to compare the changes of the values of quality of life (QoL) in patients with stable coronary artery disease and preserved left ventricular (LV) ejection fraction (EF) within 6 months after revascularization interventions (coronary artery bypass grafting — CABG, or percutaneous coronary intervention — PCI) and to identify the factors that may affect QoL changes.Materials and methods. A single­center prospective study included data from a clinical, instrumental and laboratory examination of 115 patients (91 (79.1 %) men and 24 (20.9 %) women aged 32 to 92 years (mean age — 63 ± 10) with CAD and preserved LV systolic function (LVEF ≥ 45 %) consecutively selected for CABG (n = 71) or coronary stenting (n = 44). QoL was assessed by MLHFQ, SAQ and SF­36 questionnaires before and 6 months after myocardial revascularization. Also, changes in the distance of 6­minute walking test, Doppler echocardiographic indices of the LV diastolic function and the level of the brain natriuretic peptide (BNP) were analyzed.Results and discussion. After 6 months of follow­up in the study groups, the levels of QoL according to MLHFQ, SF­36 and SAQ scores significantly improved, compared to the baseline data (p < 0.001). In both groups there was a decrease of the functional class of angina by the Canadian classification (p < 0.001). There were no significant differences in the manifestation of stable angina pectoris in the compared groups after 6 months (p = 0.237). Improvement of QoL was associated with decrease of the BNP level from baseline 108.8 (50.1 — 185.4) to 32.3 (12.6 — 57.8) pg/ml in the stenting group (p = 0.002) and from 115.4 (62.0 — 150.6) to 52.4 (20.4 — 95.9) pg/ml in the CABG group (p < 0.001). The distance of the 6­minute walk test in the stenting group increased from 223 (148 — 328) m to 550 (400 — 600) m; in the CABG group this distance was, respectively, 260 (195 — 300) and 550 (415 — 600) m.Conclusions. Thus, in patients with stable ischemic coronary disease and preserved LV systolic function after coronary artery stenting or CABG, a significant improvement of QoL values was observed, compared to the baseline data. Favorable changes in QoL may be due to a decrease of angina pectoris, improvement of the Doppler echocardiographic parameters of LV diastolic function and functional status of the patients. The above­mentioned changes were associated with decrease of the BNP level.

Published: October 2018

The aim — to increase the effectiveness of treatment in patients with dermal burns by applying pH meters to determine the depth of dermal burns and the choice treatment.Materials and methods. The results of examination and treatment of 170 patients with dermal burns with the 5 — 40 % TBSA have been analyzed. During the first, second and third day, a series of pH meters were performed: pH meter on the unharmed skin of the homologous segment, pH meter on different sites of the wound, around the wound. The pH of the wound was measured by a pH meter with a flat electrode for the skin. Clinical, biochemical, statistical methods of study were carried out. The accuracy, sensitivity and specificity of the tested method has been proved.Results and discussion. A series of pH meters were used as the basis for calculating the constant pH for each degree of burn. The values of burn depth parameters were compared with the histopathological assessment and the clinical outcome at patient discharge. The average pH after the first day for epidermal burns, which healed for 7 — 10 days, was 7.6 ± 0.1 units, for dermal superficial burns healed within 3 weeks — 8.3 ± 0.2 units and for deep dermal burns that did not heal on their own during the study period — 8.9 ± 0.3 units. The pH difference in more than 3 units was detected in 80 patients from the main group with dermal burn, pain was absent in these areas of wounds in the pain test, deep necrosis was determined visually, indicating the presence of deep dermis burns among these patients. All patients underwent early excision of necrotic tissues with plastic wounds. 20 % of the comparison group lacked the objective diagnostics at the early stage leading to delay in surgical intervention, which in turn caused a prolonged duration of a hospital stay. The high sensitivity of the pH test was determined 24 hours after the injury. Probability of the diagnosing the depth of a burn wound 24 hours after the injury by the pH metric test was equal to 84 %. Specificity of the test — 95 %.Conclusions. The contact pH metric for wounds in patients with dermal burns is an objective method to determine the depth of thermal damage in the early stages after the injury as well as predict the course of the wound process. The difference in the pH of the homologous segments one day after the injury (D pH) equal to 2 units is a clear indication for the presence of superficial dermal burns. The pH difference D pH іn 4 units demonstrates the presence of deep dermal burns and is an indication for early surgical treatment.

The aim — to study the possibilities of endovenous electric welding during the comprehensive surgical treatment of acute ascending thrombophlebitis (AAT) of great saphenous vein (GSV).Materials and methods. The treatment results in the period from 2015 to 2017 are analysed. 22 patients with AAT GSV at the age from 25 to 69 years (mean age — 49.36 ± 2.75 years). There were 5 men (22.73 %), women — 17 (77.27 %). According to the international classification of the CEAP (Clinical Etiological Anatomical Pathophysiological) class C2 was diagnosed in 4 patients, class C3 — in 9, class C4 — in 3, class C5 — in 5, class C6 — in 1. AAT GSV care was carried out with the endovenous electric welding of thrombosed vein segment. As a source of current, a multifunctional device for electric welding of live tissues EK300M («Svarmed», Ukraine) was used. Treatment results clinical evaluation was carried out considering the signs of thrombophlebitis recurrence, inflammatory infiltrate reduction in the welded vein area, pain syndrome reduction or disappearance, chronic venous insufficiency symptoms. The stability of the occlusion was monitored by ultrasound duplex angioscanning.Results and discussion. Patients with AAT GSV treated with endovenous electric welding were discharged from the hospital on the 4th — 7th day (on average — 4.86 ± 0.23 day) after the operation. In the near future, recurrence of thrombophlebitis was not fixed. In 19 (86.36 %) patients at the time of discharge from the hospital, inflammatory infiltrate along the welded vein significantly decreased, in 3 (13.64 %) — the pain syndrome managed to be completely decreased. In all operated, according to ultrasound duplex angioscanning, there was a stable occlusion of the welded veins. At 6 — 12 months in 19 (86.36 %) patients, ultrasonic duplex angioscanning revealed fibrous degeneration of welded GSV, in 3 (13.64 %) — recanalization of GSV.Conclusions. Endovenous electric welding of thrombosed GSV in 86.36 % of cases provided complete occlusion, fibrous transformation of the welded vein, reduced trauma and improved cosmetic result of the operation.

Published: October 2018

The aim — to develop a method for the breast volume determining and to compare its accuracy with the standard method (Kuklin).Materials and methods. The study included 70 women aged 29 to 58 years, an average of 42.31 ± 0.97 years, subject to surgical treatment (mastectomy) for malignant breast cancer, not exceeding 3 cm in diameter. The volume of the breast to be removed was measured before the operation by original method with the developed instrument and the Kuklin’s method and after the operation by the method of fluid displacement (MFD) — Archimedes’ method, which was considered the standard. The absolute difference in the values (ADV) and the relative difference in the values (RDV) of the measurement breast volume by the original method and the Kuklin method in relation to the MFD were calculated.Results and discussion. According to the MFD data, the volume of the breast was 82 — 978 ml, an average of 363.0 ± 24.7 ml, according to the own method and the Kuklin method, 85 — 960 ml and 100 — 920 ml, an average of 360.6 ± 24.3 ml and 353.3 ± 23.3 ml. respectively, p > 0.05. The average value of ADV according to the method of Kuklin was 29.9 ± 1.5 ml (5 — 61 ml), by original method — 10.3 ± 0.47 ml (3 — 20 ml), p = 0.001. The average value of RDV according to the method of Kuklin was 9.84 ± 0.6 % (1.7 — 31.6 %,), according to the own method — 3.4 ± 0.2 % (1.3 — 12.6 %), p = 0.001. The rate of RDV less than 5 % according to the method of Kuklin was 10.0 %, by own method — 87.1 %. The frequency of RDV more than 5 % according to the method of Kuklin was 90.0 % (mean volume of the breast 31.1 ± 1.5 ml), according to the original method — 12.9 % (average volume of the breast 11.2 ± 0.7 ml), p = 0.001.Conclusions. The developed original method for the breast volume determining provides a high measurement accuracy: the RDV rate of less than 5 % is 87.1 % (mean 10.1 ± 0.5 ml), 5.1 — 12.6 % — 12.9 % (mean 11.2 ± 0.7 ml). The developed method more accurately estimates the volume of breast than the standard method (Kuklin): the average value of ADV was 10.3 ± 0.47 ml versus 29.9 ± 1.5 ml, p = 0.001 and RDV — 3.4 ± 0.2 % vs. (9.8.4 ± 0.6 %), p = 0.001, respectively.

Published: October 2018

The aim — to study the effectiveness of preoperative portal vein embolization (PVE) in patients with cholangiocarcinoma, preparing for radical expanded liver resection (ELR).Materials and methods. PVE was performed in 148 patients with cholangiocarcinoma as fierts step for ELR from 2006 to 2015. Indications for PVE were a future liver remnant (FLR) less than 30 % of total liver volume and a bilirubin level less than 300 mg/l. The change in liver volumes was evaluated by comparsion of CT scans before PVE and before ELR, liver function was assessed with standard laboratory tests.Results and discussion. As a result, PVE managed to achieve a statistically significant increase of FLR by 45.5 %, which made it possible to exclude all patients from high­risk group and to perform ELR in 141 (95.6 %) patients. The dynamics of laboratory tests indicates the processes of cytolysis and a decrease of synthetic liver function that occur after PVE with complete restoration for 3 weeks.Conclusions. PVE allows to increase FLR in patients with cholangiocarcinomas, in the absence of complications, which gives us the right to recommend the inclusion of this technique in the protocol for the preparation of patients with cholangiocarcinomatoexpanded liver resection.
