Insights

Identifying nonorganic symptoms in children with failure to thrive (FTT) can accurately predict nonorganic FTT. However, the absence of nonorganic symptoms does not rule out this diagnosis, necessitating further investigation.

Area of Science:

  • Pediatrics
  • Child Health
  • Clinical Diagnosis

Background:

  • Failure to thrive (FTT) is a complex condition requiring accurate diagnosis.
  • Differentiating between organic and nonorganic causes of FTT is crucial for appropriate management.

Purpose of the Study:

  • To evaluate the predictive accuracy of specific symptoms and signs in classifying children with FTT into organic or nonorganic groups.
  • To determine the utility of clinical presentation in diagnosing nonorganic failure to thrive (NOFTT).

Main Methods:

  • A cohort of 208 outpatients aged 6 months to 14 years with FTT was studied.
  • Predefined clinical features were assessed as predictors for organic/nonorganic FTT.
  • All participants underwent a comprehensive diagnostic workup to rule out organic etiologies.

Main Results:

  • A high positive predictive value (96%) was observed for nonorganic symptoms in diagnosing NOFTT.
  • The negative predictive value for NOFTT was 92% when no organic symptoms were present.
  • The absence of nonorganic symptoms did not exclude a NOFTT diagnosis (41% negative predictive value).

Conclusions:

  • The presence of nonorganic symptoms, coupled with the absence of organic symptoms, strongly supports a diagnosis of NOFTT.
  • Limited laboratory investigations may be sufficient when nonorganic symptoms are identified, aiding in efficient diagnosis.

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

Formulating and Validating Nursing Diagnosis II

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.
Risk nursing diagnoses represent clinical judgments of an individual, family, or community more vulnerable to developing the health problem than others...

Formulating and Validating Nursing Diagnosis I

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.

Nursing Diagnosis

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.
The nursing diagnosis focuses on evidence-based...

Role of Communication in the Nursing Process I: Assessment and Diagnosis

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 process.

Assessment of Airway, Skin Color, and Use of Accessory Muscles

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
