RESUMO

Coronary artery disease (CAD) is a serious health problem that causes a considerable number of mortality in a number of affluent nations throughout the world. The estimated death encountered in many developed countries includes including Pakistan, reached 111,367 and accounted for 9.87% of all deaths, despite the mortality rate being around 7.2 million deaths per year, or 12% of all estimated deaths accounted annually around the globe, with improved health systems. Atherosclerosis progressing causes the coronary arteries to become partially or completely blocked, which results in CAD. Additionally, smoking, diabetes mellitus, homocystinuria, hypertension, obesity, hyperlipidemia, and psychological stress are risk factors for CAD. The symptoms of CAD include angina which is described as a burning, pain or discomfort in the chest, nausea, weakness, shortness of breath, lightheadedness, and pain or discomfort in the arms or shoulders. Atherosclerosis and thrombosis are the 2 pathophysiological pathways most frequently involved in acute coronary syndrome (ACS). Asymptomatic plaque disruption, plaque bleeding, symptomatic coronary blockage, and myocardial infarction are the prognoses for CAD. In this review, we will focus on medicated therapy which is being employed for the relief of angina linked with CAD including antiplatelet medicines, nitrates, calcium antagonists, blockers, catheterization, and the frequency of recanalized infarct-related arteries in patients with acute anterior wall myocardial infarction (AWMI). Furthermore, we have also enlightened the importance of biomarkers that are helpful in the diagnosis and management of CAD.

RESUMO

Coronary artery disease (CAD) is a cardiovascular disease of the blood vessels that makes vessels, narrow and hardened and difficult to supply blood to the heart. The epidemiology of CAD disease is a common clinical syndrome of a global health priority and the burden is increasing at an alarming rate worldwide. The prevalence of CAD not only increases mortality, morbidity and worsens the patient quality of life but also puts a huge burden on the overall healthcare system. The novel risk factors include: cholesterol level, cigarette smoking, diabetics, obesity, and hypertension, respectively are the causative agents of CAD. Furthermore, the etiology of CAD is also a very complex process and several interrelated etiological factors are involved in the pathogenesis of CAD. The signs and symptoms of CAD appear like angina, heart failure, and dyspnea, myocardial infarction, and arrhythmia, respectively. The management and diagnosis of CAD include different types of medications that are used nowadays for the treatment of this disease. The highlights of the present review focused on stent technology and its useful applications. Finally, we also addressed the benefits of the stent, and its potential complications, effectiveness, indication, and contraindication that play a significant role in the recovery of CAD disease.

RESUMO

Cancer is one of the most prevalent diseases worldwide. The most prevalent condition in women when aberrant cells develop out of control is breast cancer. Breast cancer detection and classification are exceedingly difficult tasks. As a result, several computational techniques, including k-nearest neighbor (KNN), support vector machine (SVM), multilayer perceptron (MLP), decision tree (DT), and genetic algorithms, have been applied in the current computing world for the diagnosis and classification of breast cancer. However, each method has its own limitations to how accurately it can be utilized. A novel convolutional neural network (CNN) model based on the Visual Geometry Group network (VGGNet) was also suggested in this study. The 16 layers in the current VGGNet-16 model lead to overfitting on the training and test data. We, thus, propose the VGGNet-12 model for breast cancer classification. The VGGNet-16 model has the problem of overfitting the breast cancer classification dataset. Based on the overfitting issues in the existing model, this research reduced the number of different layers in the VGGNet-16 model to solve the overfitting problem in this model. Because various models of the VGGNet, such as VGGNet-13 and VGGNet-19, were developed, this study proposed a new version of the VGGNet model, that is, the VGGNet-12 model. The performance of this model is checked using the breast cancer dataset, as compared to the CNN and LeNet models. From the simulation result, it can be seen that the proposed VGGNet-12 model enhances the simulation result as compared to the model used in this study. Overall, the experimental findings indicate that the suggested VGGNet-12 model did well in classifying breast cancer in terms of several characteristics.

RESUMO

INTRODUCTION: Helicobacter pylori (H. pylori) colonization is prevalent all over the world, and it is associated with low socioeconomic status, poor hygiene, and overcrowding. Its eradication is important since it is an etiologic agent for gastritis, peptic ulcer, gastric carcinoma, and mucosa-associated lymphoid tissue lymphoma. Different regimens are available for the eradication of H. pylori and include triple therapy and sequential therapy. Our study aims to compare the efficacy of triple therapy versus sequential therapy in the eradication of H. pylori. MATERIAL AND METHODS: This randomized clinical trial was conducted at the Pakistan Institute of Medical Sciences Hospital, Islamabad, from September 2016 to September 2017 after the approval of the institutional review board. A total of 160 patients were enrolled and equally divided into two, group A and group B. A twice-daily dose of amoxicillin 1,000 mg, rabeprazole 20 mg, and clarithromycin 500 mg was given to group A for 10 days, while group B was initially given rabeprazole 20 mg and amoxicillin 1,000 mg two times daily for the first five days (i.e., induction phase), followed by triple therapy that included rabeprazole 20 mg, clarithromycin 500 mg, and metronidazole/tinidazole 500 mg twice daily for the next five days. A negative stool antigen test performed four weeks after the completion of therapy was considered an effective eradication. A proforma was used to collect data that included age, gender, city or province of residence, family income, group (group A or group B), and eradication efficacy. Analysis of the data was performed using the Statistical Package for the Social Sciences version 17 (SPSS Inc., Chicago, USA). RESULTS: A total of 160 patients were included, with mean age and standard deviation of 40.02±24.4 years. The male/female ratio was 1.8:1. Successful eradication of H. pylori achieved in group A was 67.5% (N=54) in comparison to group B, which was 95% (N=76) (p=0.001). CONCLUSION: Sequential therapy was superior to triple therapy in H. pylori eradication.

RESUMO

Introduction: Acute appendicitis is one of the leading causes of acute abdominal pain and surgical emergency. Stump appendicitis is a known complication of appendectomy whereby a retained appendiceal tip serves as a nidus for recurrent bouts of inflammation. Nevertheless, full-blown appendicitis of the vermiform appendix after a prior appendectomy remains a diagnostic conundrum. Case presentation: A 45-year-old woman presented with a six-month history of right iliac fossa pain. Pertinently, she had undergone a prior open appendectomy twelve years ago. Further investigative workup revealed full-blown appendicitis, which was not attributable to a retained appendiceal stump. A subsequent laparoscopic appendectomy was performed, and the resultant specimen was sent for further evaluation, confirming the diagnosis of recurrent appendicitis. Clinical discussion: Acute appendicitis is one of the most common life-threatening abdominal surgical emergencies worldwide, with 300000 appendectomies performed annually in the United States alone. Stump and chronic appendicitis are two separate and exceedingly rare clinical entities that may present simultaneously and develop serious complications unless promptly recognized and appropriately managed. The present paper prompts the clinicians to distinguish amongst the two at the initial surgery in order to thwart further exacerbations. Conclusion: While stump appendicitis is a rare but well-characterized complication of a prior appendectomy, full-blown appendicitis of vermiform appendix remains elusive. It is therefore imperative to distinguish between a duplicated and a recurrent appendix at the initial operative procedure to facilitate optimal patient management.

RESUMO

Introduction: Pancreatic pseudocysts remain a feared complication of acute or chronic pancreatitis and are often characterized by collections of fluids due to underlying damage to the pancreatic ducts, culminating in a walled-off region bereft of an epithelial layer but surrounded by granulation tissue. While fungal infections of pancreatic pseudocysts are rarely encountered, candida albicans remains the most frequently implicated organism. Case presentation: A 55-year-old male presented with pain in the left-hypochondriac region, accompanied by non-bilious emesis and nausea. Interestingly, the patient also tested positive for a COVID-19 infection. Investigative workup divulged enhancing pancreatic walls with a radiologic impression consistent with a pancreatic pseudocyst. An ultrasound-guided external drainage was performed; the drainage was conducted unremarkably, with the resultant fluid collection revealing the presence of Candida Glabrata. The patient was commenced on antifungal therapy and continues to do well to date. Discussion: Infectious ailments of pancreatic pseudocysts remain a widely known complication of acute pancreatitis. While it is rare, fungal infection is a crucial consideration for patients with pancreatic pseudocysts, especially in the context of a lack of an adequate response to antibiotics, deterioration, comorbidities, and immunocompromised states. Conclusion: Rapid identification of the microbe responsible for pancreatic pseudocyst infection is vital for time-sensitive treatment and a more rapid recovery, curbing associated morbidity and mortality.

RESUMO

Introduction: Meckel's diverticulum is a congenital anomaly that is often detected incidentally. When it presents symptomatically, it causes painless gastrointestinal bleeding. Nevertheless, in rare instances, it can cause acute intestinal obstruction, often obscuring the true clinical picture. Case presentation: A 31-year-old male presented to the emergency department with a 24-h history of unremitting nausea, biliary emesis, abdominal distension, and absolute constipation. After ruling out the most common etiologies of acute bowel obstruction, radiological imaging was obtained and was suggestive of meckel's diverticulum. Laparoscopic meckel's diverticulectomy was performed, with the subsequent histopathological analysis confirming ectopic gastric tissue. Discussion: Meckel's diverticulum occurs consequent to incomplete obliteration of the vitelline or omphalomesenteric duct, which connects the developing intestines to the yolk sac. It is found in roughly 2% of the population, of which only about 4% may become symptomatic due to any number of complications. Specifically, small bowel obstruction (SBO) and diverticulitis secondary to ectopic gastric or pancreatic tissue are the most common presentations of symptomatic MD. Conclusion: Although relatively rare in adults, MD should be considered in the list of differentials in patients with intussusception leading to SBO, especially on a background history unremarkable for the most common etiologies causing SBO including post-operative adhesions and hernias.

RESUMO

Left-sided gallbladder (LSGB) is a rare anatomic variation that, while benign in the context of its transposition, is of significant intraoperative importance. Due to its association with other anatomic anomalies involving key structures in the hepatobiliary system, discovering it intraoperatively as opposed to preoperatively suddenly increases the difficulty of a gallbladder procedure.

RESUMO

Fallopian tube torsion secondary to paraovarian or paratubal cyst is a rare gynecological cause of acute abdomen. The condition has no distinctive signs and symptoms. There are no characteristic features on radiological imaging, making preoperative diagnosis very difficult. Paraovarian cysts that are less than 4 cm in size are mostly asymptomatic and found incidentally during a pelvic examination or radiological imaging. It seldom leads to any complications like fallopian tube torsion hemorrhage or rupture. We report a case of an adolescent girl, who presented with severe abdominal pain. Transabdominal ultrasound was suggestive of a cystic structure less than 4 cm in size in the left adnexa. Doppler ultrasound showed normal blood flow to both ovaries. Diagnostic laparoscopy was performed, which revealed a twisted left-sided fallopian tube with a fimbrial paraovarian cyst. Detorsion and paraovarian cystectomy was performed. Although paraovarian cysts are mostly asymptomatic, those arising near the fimbrial end can lead to torsion of the fallopian tube, therefore it should always be considered a possible cause of acute abdomen in adolescent girls with adnexal cysts on ultrasound. Timely surgical intervention can prevent complications such as fallopian tube necrosis, gangrene, removal of the tube, and its long-term implications especially in women of the reproductive age group.

RESUMO

Breast sarcomas remain a rare malignancy and are noted to portend a particularly dismal prognosis. Due to their high rates of recurrence, a surgical excision with negative margins remains the preferred treatment modality. Nevertheless, their sparse prevalence often poses a diagnostic conundrum. In this report, we chronicle the case of a 46-year-old female with a recurrent breast sarcoma that was treated with wide local excision. Interestingly, no flap reconstruction, skin graft surgery, or primary wound closure was performed, and the resultant wound was left to heal by secondary intention. The patient continues to do well to date, with no postoperative complications.

RESUMO

Ovarian tumors occurring secondarily to metastatic colorectal carcinoma remain a rare occurrence. Since ovarian tumors remain predominantly asymptomatic in the initial stages, they are often diagnosed incidentally. The vague, non-specific symptoms elicited by a secondary ovarian carcinoma, coupled with a histopathology remarkably similar to that evoked by primary ovarian tumors, render its ascertainment a diagnostic challenge. We hereby delineate an interesting case of a metachronous ovarian adenocarcinoma in a 19-year-old patient with a prior medical history significant for colorectal carcinoma treated with hemicolectomy. Subsequent diagnostic workup divulged a mass in her left adnexal region, which was ultimately diagnosed as a metastatic colon adenocarcinoma to the ovary. Unfortunately, the patient succumbed to the aggressive malignancy and did not survive. We therefore aim to accentuate the diagnostic and therapeutic dilemmas fomented by ovarian adenocarcinomas that arise secondarily to primary colorectal cancers.

RESUMO

Introduction Soft tissue sarcomas remain an exceedingly rare malignancy. While soft tissue sarcomas boast a high mortality rate, their characteristics and behavior patterns are poorly understood. This study aims to evaluate the various aspects that pertain to soft tissue sarcomas, including their histology, tumor characteristics, survival rates, and therapeutic modalities. Methods A retrospective study analyzing the data from 19 patients presenting over four years with a histologically confirmed diagnosis of soft tissue sarcomas was conducted. The patients were studied for various parameters, including tumor site and the particular pathological subtypes. The data obtained were analyzed using the SPSS 23.0 statistical software (IBM Corporation, Armonk, NY), and the results were then tabulated. Results A total of 19 patients with a confirmed diagnosis of a soft tissue sarcoma were included in the study. The mean age of the patients included was 45.32 ± 16.88 years. Wide local excision was the most common surgical procedure employed for the resection of these tumors. Within the cohort, the mortality rate was noted to hover at 10.52%. Gastrointestinal stromal tumors were observed in 21% of the patients and were therefore the most common histological subtype. Of the patients included, 42.10% required blood transfusion during the perioperative time. Most of the tumors were noted to be intermediate grade, with high-grade tumors observed in 26.3% of the cases. Conclusion Soft tissue sarcomas remain a rare but potent cause of death in developing countries. The diversity of the tissues that they afflict renders their prompt detection a diagnostic challenge. A meticulous exploration of the various characteristics honed by soft tissue sarcomas, such as the particular histological subtype and the associated mortality rates, can better elucidate the prognosis and the eventual disease outcomes.

RESUMO

Background Breast cancer remains the most common cause of cancer related mortality amongst women in Pakistan. Postoperative complications can demoralize the patients and potentially delay adjuvant treatment, leading to adverse outcomes. The overarching aim of the study is to delineate the early postoperative outcomes of breast cancer surgery in Pakistan. Materials and Methods A retrospective study involving patients who underwent breast cancer surgery from June 2016 to December 2019 was conducted. Perioperative morbidities (30 days) were evaluated and documented. The results obtained were analyzed using the SPSS 23 software (IBM Corporation, Armonk, NY). Results A total of 94 patients were included in the study, with the mean age of 50±12.8 years. Breast conserving surgery was performed in 32% (n=31) of the patients, while the remaining 68% (n=63) underwent modified radical mastectomy. The most common complications were seroma formation, flap necrosis and hematoma formation and were observed in 5.3% (n=5), 4.3% (n=4) and 3.2% (n=3) of the patients, respectively. Conclusion Early postoperative complications can delay the commencement of adjuvant systemic therapy required for further management of breast cancer. These complications elicit equally grave consequences for patients undergoing breast conserving surgery and modified radical mastectomy.

RESUMO

Background Affections of the gallbladder remain exceedingly ubiquitous and often warrant surgical intervention. The histopathological patterns represent a spectrum, ranging from cholecystitis to gallbladder carcinoma. The present study aims to delineate the occurrence of various gallbladder histopathologies in a tertiary care hospital in Pakistan. Methods A retrospective study was conducted at Maroof International Hospital, Islamabad, Pakistan. Histopathological records of 442 gallbladder specimens obtained from cholecystectomy were analysed. The prevalence of various histopathological outcomes was assessed. The data were eventually analysed using the SPSS 23.0 software (Armonk, NY: IBM Corp.). Thereafter, the distribution of various gallbladder histopathologies was tabulated across gender.  Results Of the 442 patients included, 330 were females and 112 were males, with the mean age hovering at 45.77±14.65 years. The most common histopathological findings were chronic cholecystitis and cholesterolosis, observed in 78.6% and 32.8% of the patients, respectively. While only one case of gallbladder adenocarcinoma was observed, multiple specimens divulged premalignant lesions including reactive atypia and intestinal metaplasia. Conclusions Diseases of the gallbladder often mandate prompt surgical intervention. Of these, chronic cholecystitis, which is an established risk factor for gallbladder carcinoma, is exceedingly common. The employment of histopathological techniques remains imperative in the detection of premalignant and malignant lesions that might otherwise evade macroscopic detection and thus progress to adenocarcinoma.

RESUMO

Ovarian carcinomas remain a cause of soaring mortality in the general population. Due to their anatomical location in the pelvis, malignant ovarian transformations often evade early detection, reaching astronomical proportions before eliciting clinically obvious symptoms. Epithelial ovarian carcinomas encompass a concoction of tumours derived from the ovarian surface epithelium, and are further subdivided into several subtypes ascertained primarily through histopathological workup. Of these subtypes, endometrioid ovarian carcinoma is noted to be a particularly well-differentiated tumour that often presents early in the disease course. Contrarily, advanced-stage tumours manifest a vague constellation of symptoms, such as abdominal distension and bloating, resulting in dilatory tumour detection. We hereby delineate an interesting case of a high-grade ovarian endometrioid carcinoma that, due to its vague presenting symptoms and a concomitant history of amenorrhea, was erroneously regarded as pregnancy. Subsequent diagnostic workup divulged a bilateral endometrioid ovarian carcinoma with associated serosal involvement and extensive lymph-vascular invasion.

RESUMO

Liposarcomas are exceedingly rare entities that evoke malignant transformation of connective tissue and fat cells. These tumours occur throughout the soft tissues of the body, afflicting a myriad of regions. In the adult population, liposarcomas represent the most prevalent subtype of sarcomas, and often arise de novo. Retroperitoneal liposarcomas (RLS) are a ubiquitous subset of sarcomas that, due to their deep location in the hollow abdomen, can grow to astronomical proportions before manifesting any noticeable symptoms; a prompt diagnosis of RLS is therefore often rendered dilatory. We hereby delineate the case of a 43-year-old woman who presented with vague left hemiabdominal distention and discomfort. A subsequent computed tomography scan divulged a giant retroperitoneal growth impaling on and thus displacing the pancreas. A compartmental, en bloc resection was performed, with subsequent histopathology of the excised specimen revealing a well-differentiated liposarcoma. The surgical intervention was curative and led to an uneventful recovery. This paper highlights the pertinence of surgical management as an appropriate treatment modality for a complete resection of RLS.
