Postmortem diagnosis of invasive meningococcal disease
Emerging Infectious Diseases
|February 26, 2014
Abstract:
We diagnosed invasive meningococcal disease by using immunohistochemical staining of embalmed tissue and PCR of vitreous humor from 2 men in New York City. Because vitreous humor is less subject than other body fluids to putrefaction, it is a good material for postmortem analysis.
Insights
Diagnosing invasive meningococcal disease postmortem is possible using immunohistochemical staining and PCR on vitreous humor. This method offers a reliable approach for analyzing biological samples, even after decomposition.
Area of Science:
- Microbiology
- Forensic Pathology
- Ophthalmology
Background:
- Invasive meningococcal disease (IMD) poses diagnostic challenges, particularly in postmortem cases.
- Timely and accurate diagnosis is crucial for public health surveillance and understanding disease transmission.
Observation:
- Two cases of invasive meningococcal disease were diagnosed in deceased individuals in New York City.
- Analysis involved immunohistochemical staining of embalmed tissue and polymerase chain reaction (PCR) of vitreous humor.
Findings:
- Vitreous humor proved to be a valuable biological sample for postmortem analysis due to its resistance to putrefaction.
- The combination of immunohistochemistry and PCR enabled definitive diagnosis of Neisseria meningitidis.
Implications:
- This study highlights the utility of vitreous humor in postmortem microbiological investigations.
- The described diagnostic approach can aid in identifying the causative agents of infectious diseases in challenging forensic cases.
- Improved postmortem diagnostics contribute to more comprehensive epidemiological data and disease control strategies.

Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.

A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.

The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.

Nursing diagnoses represent a problem validated by major defining characteristics. There are four categories of nursing diagnoses: problem-focused, risk, health promotion or wellness, and syndrome. The anatomy of a nursing diagnosis includes three components: problem statement or diagnostic label, defining characteristics, and related factors.

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

The nursing process uses scientific reasoning, problem-solving, and critical thinking to guide nurses in providing patients with appropriate care. This process is a systematic approach to recognize, avoid, and treat current or potential health issues while promoting the patient's well-being.
The nursing process considers the patient's emotional and physical well-being. The process can be repeated or stopped at any point if judged essential. Assessment is the first step in the nursing...
