Scoring system
A white blood cell count greater than 15,000 cells/mm3 and serum sodium level less than 135 mmol/L have a sensitivity of 90% in detecting the necrotizing soft tissue infection. It also has a 99% chance of ruling out necrotizing changes if the values have shown otherwise. Various scoring systems are being developed to determine the likelihood of getting necrotizing fasciitis, but a scoring system developed by Wong and colleagues in 2004 is the most commonly used. It is the laboratory risk indicator for necrotizing fasciitis (LRINEC) score, which can be used to stratify by risk those people having signs of severe cellulitis or abscess to determine the likelihood of necrotizing fasciitis being present. It uses six laboratory values: C-reactive protein, total white blood cell count, hemoglobin, sodium, creatinine, and blood glucose. A score of 6 or more indicates that necrotizing fasciitis should be seriously considered. The scoring criteria are:

CRP (mg/L) ≥150: 4 points
WBC count (×103/mm3)
<15: 0 points
15–25: 1 point
>25: 2 points
Hemoglobin (g/dL)
>13.5: 0 points
11–13.5: 1 point
<11: 2 points
Sodium (mmol/L) <135: 2 points
Creatinine (umol/L) >141: 2 points
Glucose (mmol/L) >10: 1 pointHowever, the scoring system has not been validated. The values would be falsely positive if any other inflammatory conditions are present. Therefore, the values derived from this scoring system should be interpreted with caution. About 10% of patients with necrotizing fasciitis in the original study still had a LRINEC score <6. A validation study showed that patients with a LRINEC score ≥6 have a higher rate of both death and amputation.
Postpartum psychosis is a rare condition, affecting 1-2 per 1000 women. Postpartum psychosis is classified as a psychiatric emergency and requires hospital admission.Additionally, a variety of medical co-morbidities can mimic or worsen psychiatric symptoms. Prevention
Screening
There are no specific screening recommendations for postpartum blues. Nonetheless, a variety of professional organizations recommend routine screening for depression and/or assessment of emotional well-being during pregnancy and postpartum. Universal screening provides an opportunity to identify women with sub-clinical psychiatric conditions during this period and those at higher risk of developing more severe symptoms. Specific recommendations are listed below:

American College of Obstetrics and Gynecology (ACOG): In 2018, ACOG recommended universal screening for depression and anxiety using a validated tool at least once during pregnancy or postpartum, in addition to a full assessment of mood and well-being at the postpartum visit. This is in addition to existing recommendations for annual depression screening in all women. American Academy of Pediatrics (AAP): In 2017, the AAP recommended universal screening of mothers for postpartum depression at the 1-, 2-, 4-, and 6-month well child visits. United States Preventative Services Task Force (USPSTF): In 2016, the USPSTF recommended depression screening in the general adult population, including pregnant and postpartum women. Their recommendations did not include guidelines for frequency of screening. Primary prevention
Given the mixed evidence regarding causes of postpartum blues, it is unclear whether prevention strategies would be effective in decreasing the risk of developing this condition.
