Which of the following statements with regard to Enteric perforation are correct? 1. Salmonella typhi is the causative organism for Enteric fever 2. Enteric perforation characteristi- cally occurs during third week of illness 3. Typhoid ulcers are placed trans- versely to the long axis of the gut 4. Terminal ileum is the most common site for enteric perfora- tion Select the correct answer using the code given below :
This question asks to identify the correct statements regarding Enteric perforation. Let's analyze each statement:
Statement 1: $Salmonella typhi$ is the causative organism for Enteric fever.
Analysis: $Salmonella typhi$ is indeed the bacterium responsible for causing typhoid fever, a common form of enteric fever. Therefore, this statement is correct.
Statement 2: Enteric perforation characteristically occurs during the third week of illness.
Analysis: While intestinal complications, including perforation, often peak during the third week of typhoid fever, it is not universally characteristic or exclusively limited to this period. Complications can arise earlier or later. Thus, this statement is considered incorrect in the context of needing a 'characteristic' feature.
Statement 3: Typhoid ulcers are placed transversely to the long axis of the gut.
Analysis: Typhoid ulcers, which are areas of necrosis and inflammation in the intestinal lining (Peyer's patches), are described in relation to their orientation. According to this statement, they are placed transversely. This statement is considered correct.
Statement 4: Terminal ileum is the most common site for enteric perforation.
Analysis: The terminal ileum, being rich in Peyer's patches where $Salmonella typhi$ preferentially localizes, is the most frequent location for typhoid-related intestinal perforations. Therefore, this statement is correct.
Based on the analysis, statements 1, 3, and 4 are correct, while statement 2 is incorrect.
The correct option is the one that includes statements 1, 3, and 4.
