Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.

Background: The high number of knee osteoarthritis cases could lead arthroplasty more frequent. Total Knee Replacement (TKR) surgery procedure is at risk of massive bleeding. Bleeding can affect albumin levels and the onset of intra-compartment pressure on the nerves. The use of tranexamic acid could be done to reduce bleeding.Objective: Proving the effect of intravenous tranexamic acid administration on patients who will undergo TKR surgery.Methods: The experiment was conducted experimentally using primary laboratory data obtained before and after surgery in patient which will be performed TKR operation starting from April 2017.Result: There are 64 patients who had undergone total knee replacement surgery. The mean preoperative hemoglobin in the tranexamic acid group and without tranexamic acid was 13.06±1.46g/dl and 12.44±0.87g/dl. The mean hemoglobin after surgery was 10.29 ±1.14 g/dl and 9.16±0.97 g/dl. In the group receiving tranexamic acid, 32 (100%) reported low postoperative VAS scores, did not require blood transfusions and did not require albumin transfusion. Groups not receiving tranexamic acid, 32 (100%) moderate postoperative VAS scores, 4 people (12.5%) required the blood transfusion, and 3 (9.4%) required transfusion of albumin.Conclusion: The results of this study showed that the group given tranexamic acid had higher hemoglobin levels after surgery than the untreated group of tranexamic acid; there was no difference in albumin levels after surgery in both groups; the administration of tranexamic acid will decrease the amount of blood loss, decrease the degree of pain, and decrease the need for blood transfusions after total knee replacement surgery.

A 15 years old girl with main complaint a mass in her pedis since she was 2 years old. The mass' size was equal with the skin, the color was red, and there were no pain although in walk. The mass got bigger and it started to cause pain when used in walking. The mass get bleedy after it had been crushed by stone,. Then, bleeding always happen when there was a contact, although only soft touch. Patient had contact history with tuberculosis patient. Tuberculoma is a mass that is caused by infection of bacil mycobacterium tuberculosis, while hemangioma is a soft tissue mass that formed by vascular. Hemangioma commonly happened in children about 4-10% in children's tumor. It happened in a girl 3-5 times more than in a boy. Both of them are rare happen in the same time, especially in pedis. From this case, we can find both type in the same patient. For this case of soft tissue tumor, we use open biopsy. After we know the result, the best treatment for hemangioma and tuberculoma of the pedis for this case is below knee amputation. The best treatment for this case is amputation, and after amputation, the patient never complain about pain anymore, she feels satisfied and overall her quality of life is improving Keywords: Hemangioma pedis, Tuberculoma pedis, 15 years old Correspondence : orioctapaedi@gmail.com ABSTRAKSeorang perempuan berusia 15 tahun dengan keluhan utama massa di pedisnya sejak dia berusia 2 tahun. Ukuran massa sama dengan kulit, warnanya merah, dan tidak ada rasa sakit meski digunakan untuk berjalan. Massa semakin besar dan mulai menimbulkan rasa sakit saat digunakan dalam berjalan. Massa menjadi mudah berdarah setelah pernah tersandung batu. Kemudian, pendarahan selalu terjadi saat ada kontak, meski hanya sentuhan lembut. Pasien memiliki riwayat kontak dengan pasien tuberkulosis. Tuberkuloma adalah massa yang disebabkan oleh infeksi basil Mycobacterium tuberculosis, sedangkan hemangioma adalah massa jaringan lunak yang terbentuk oleh pembuluh darah. Hemangioma biasanya terjadi pada anak-anak dan merupakan sekitar 4-10% pada tumor anak-anak. Hemangioma terjadi pada anak perempuan 3-5 kali lebih banyak daripada pada anak laki-laki. Keduanya jarang terjadi pada saat bersamaan,
