Final answer:
The case studies provide scenarios of postoperative complications and the need for diagnostic testing like CT scan, urine analysis, and blood work, and touch on subjects like bariatric surgery and obesity management.
Step-by-step explanation:
The provided case studies describe various clinical scenarios. In the first, Roberta developed abdominal pain and a high fever, along with blood in her urine after undergoing laparoscopic cholecystectomy. The presented symptoms, like burning sensation during urination, suggest possible complications like a urinary tract infection (UTI) or another procedure-related issue that requires immediate medical evaluation.
In Marisa's situation, her severe abdominal pain, swollen lymph nodes, fatigue, fever, and recent medical history indicate a complex case that demands further diagnostic tests such as a CT scan and blood work to identify infections or other postoperative complications like appendicitis.
The historical case of the male patient from 1861 showcases a serious condition with diffuse gangrenous inflammation and paralysis, which would have required thorough medical intervention probably not available at that time.
The last case implies the subjects of bariatric surgery, obesity, and basal cell carcinoma, suggesting a focus on weight management strategies, potential surgical interventions, and a separate case of skin cancer which is not elaborately discussed here but highlights the importance of multidisciplinary approaches in patient care.
