When there is metastasis to the bones, it mimics multiple myeloma on radiological skeletal survey. The objective of this report is to draw attention to this rare carcinoma which, usually, presents as a small painless nodule within the first three decades of life. We report this rare case of SS in a middle aged Nigerian lady who presented initially at National Orthopaedic Hospital (NOHE) with chronic severe right hip pain in which the initial radiological skeletal survey strongly suggested multiple myeloma. Definitive diagnosis and management of this case of synovial sarcoma was very challenging to the patient and managing unit. Conclusion: Early diagnosis of SS is critical at which point surgical excision or radiotherapy may be the preferred treatment option to achieve a favorable outcome. When metastasis is extensive, chemotherapy becomes the therapy of choice and it does not come cheap or easily available.","PeriodicalId":299013,"journal":{"name":"International Academic Research Journal of Surgery","volume":"2019 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124026733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hemorrhagic presentation of AVM is associated with significant morbidity and mortality; it is an independent predictor of future hemorrhage. AVM rupture is one of the most frequent and important causes of hemorrhagic stroke during pregnancy and puerperium. Whether the risks of AVM rupture increases during pregnancy and puerperium is controversial, but maternal physiological changes in hemodynamics, blood volume, and hormonal effects on the vessel walls could potentially increase the risk of hemorrhage from AVMs during pregnancy and in the postpartum period. For AVM during pregnancy and puerperium, previous studies have demonstrated histologic changes in arteries and arterioles of pregnant women, thought to be mediated by progesterone; the changes included fragmentation of reticular fibers and loss of normal corrugation of elastic fibers, which might play a role in the increased risk for AVM hemorrhage during pregnancy. However, there is insufficient evidence to guide management decisions for ruptured AVMs during pregnancy, and further well-designed, multicenter, perspective clinical trials are needed. We report the case of a young woman, who had an emergency ceasarean surgery for a headeck and consciousness disorder witch evoked eclampsia, while in fact; she had a rupture of arteriovenous malformation following the rupture of a cerebral Arterio-venous malformation in cerebral imaging.","PeriodicalId":299013,"journal":{"name":"International Academic Research Journal of Surgery","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114554125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advanced energy sources, such as the harmonic scalpel, though expensive, may provide the advantage of shorter operating time by reducing smoke, bloodless dissection in the GB bed, lower risk of bleeding from the cystic artery due to secure vessel sealing, and avoiding the use of a larger number of titanium clips. Thus, a study was undertaken to compare the advantages of Two Clips Laparoscopic Cholecystectomy (TCLC) over conventional laparoscopic cholecystectomy (CLC).

Traffic accidents and falls are the most prevalent causes of trauma. In this case, a CT scan is the gold standard for detecting BAT. However, there are several limits to this examination, particularly in terms of availability, cost, and radiation exposure. In BAT, FAST assists in the detection of intraabdominal free fluid. Case Description: Three pediatric patients with stable hemodynamics underwent BAT in this case series. All three patients were below 17 years old and had stomach discomfort due to a traffic accident. All three patients tested positive for FAST. Then, a contrast CT scan of the abdomen revealed a splenic rupture in the three patients and a splenic rupture and liver rupture in one of them. All the patients were hemodynamically stable before being treated with symptomatic medicines in a conservative (non-surgical) manner. All of the patients had satisfactory outcomes and could return home without undergoing surgery. Conclusion: Both FAST and CT scans do not affect therapeutic care, that were conservative management in these patients with stable hemodynamics. As a result, FAST may be a less expensive examination alternative, reducing radiation exposure and lowering the risk of cancer in children in the future.","PeriodicalId":299013,"journal":{"name":"International Academic Research Journal of Surgery","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114229038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This number increases annually (Departemen Kesehatan RI, Statistik morbiditas dan mortalitas di rumah sakit; 2005-2010). Breast cancer in women is associated with progesterone hormone, which is a female reproductive hormone (DeVita, V. T. et al., 2011). Both in-vivo and in-vitro researches on the effect of progesterone on breast cancer progression has been carried out in other studies. However, clinical research on this topic is rarely done. Therefore, the authors were interested in doing this research (Sobri, F. B. et al., 2018). Material and Methods: This was cross-sectional research. This was a follow-up study from research conducted five years ago in The Department of Surgical Oncology Dr. Moewardi Hospital Surakarta between March to May 2015. Subjects of this study were Luminal A breast cancer patients carried out for progesterone examination in the blood and assessed for TNM stage. Evaluation of progesterone levels in the blood and TNM stage were performed in November to December 2020. Statistical analysis: In this study data, bivariate and multivariate analyses were carried out. Logistic regression test for ordinal data was used for bivariate analysis, whereas Chi-square/Fisher exact test was performed for data with nominal dichotomy scale. Multivariate analysis was done using logistic regression with a significance p-value less than 0.05 in the bivariate analysis to determine the odds ratio. Data was significant if p less than 0.05. Results: Based on bivariate analysis with logistic regression test and multivariate analysis, progesterone levels in the blood of Luminal A breast cancer patients influence the breast cancer progression, with p-value = 0.037 on bivariate analysis and p-value = 0.031 on multivariate analysis. Increased progesterone levels in the blood of Luminal A breast cancer patients multiplied the risk of breast cancer progression by 12 times.

The cause of the disease lies in quantitative (type 1, type 3) or qualitative (type 2) abnormalities of vonWillebrand factor (vWF). vWF has two important functions in coagulation. On the one hand, it circulates in plasma as a carrier protein for factor VIII and thus has a protective function; on the other hand, it is responsible for platelet adhesion to the subendothelium of injured vessels and platelet aggregation . The risk of bleeding varies according to the severity of the injury. The therapeutic management strategy depends on the type of disease.

Methods: This cohort study was conducted in Sanglah General Hospital, from 2016 to 2021. All data was obtained by Cancer Registry and electronic medical records. There were nine variables that being analyzed in this study, such as age, gender, side, size, consistency, vascularization, node, and cytology. The data was pooled and analyzed in SPSS and R studio.

Further, nomogram was developed to plot the probability of cancer from significant variables. By using only cytology parameter, the cancer predictive value was only less than 10%. Even age and consistency parameter by physical examination gave a higher value of 30% predictive value.
