Presenting History
In children presenting with suspected Severe Acute Malnutrition (SAM), elicit the chronicity of weight loss, muscle and fat wasting, edema progression, changes in appetite, behavioral alterations, and precipitating infections.
- Wasting & Failure to Thrive:
- Onset & Course: When was the failure to gain weight or progressive loss of weight first noticed?
- Fat & Muscle Loss: Is there visible loss of subcutaneous fat over the buttocks ("baggy pants" appearance), thighs, arms, and face ("old man facies" / wizened appearance)?
- Activity & Behavior: Has the child become apathetic, listless, intensely irritable on handling, or ceased playing and walking?
- Edema Characteristics:
- Onset & Distribution: When did the swelling start? Did it begin over the dorsum of both feet and ankles (bilateral pitting pedal edema - hallmark of kwashiorkor)?
- Progression: Has it extended up the legs, to hands, or facial puffiness?
- Appetite & Feeding Status:
- Appetite: Is the child actively refusing feeds or taking small sips? Can the child pass an appetite test with RUTF?
- Diarrheal Illness: Any watery loose stools, vomiting, or abdominal distension?
- Skin & Hair Changes:
- Skin: Are there dark hyperpigmented peeling patches over pressure areas, perineum, or thighs (flaky paint dermatosis)?
- Hair: Has hair become thin, sparse, brittle, light brown or reddish, with alternating light and dark bands (flag sign)?
Negative History (3C 1D Framework)
| Category | Pertinent Negative Question | Rationale / Significance |
|---|---|---|
| Causes | Preceding Infections: No history of measles, severe pertussis, or recurrent pneumonia. Faulty Feeding: No delayed complementary feeding or early cessation of breastfeeding. Tuberculosis Contact: No contact with a chronic cough / pulmonary TB adult. HIV Risk: No parental risk factors, chronic thrush, or recurrent suppurative otitis. | Measles and pneumonia frequently precipitate catastrophic acute catabolism. Inadequate caloric density and protein intake is the primary etiology. Occult tuberculosis is the major underlying secondary cause. HIV enteropathy and immunosuppression accelerate wasting. |
| Complaints (Differentiating) | Chronic Diarrhea / Steatorrhea: No history of bulky, pale, foul-smelling, floating stools. Renal / Cardiac Edema: No history of morning periorbital swelling, oliguria, frothy urine, or cyanosis. | Differentiates primary nutritional SAM from celiac disease and cystic fibrosis. Distinguishes kwashiorkor edema from nephrotic syndrome and CCF. |
| Complications | Hypoglycemia: No history of sweating, tremors, sudden limpness, or convulsions. Hypothermia: No history of cold extremities or axillary temperature $<36.0^\circ\text{C}$. Severe Dehydration / Shock: No history of lethargy, sunken eyes, rapid weak pulse, or delayed CRT. Sepsis / Severe Pneumonia: No history of fast breathing, chest indrawing, or grunting. | Hypoglycemia ($<54\text{ mg/dL}$) causes sudden neurological mortality in SAM. Impaired thermoregulation and reduced metabolic rate lead to hypothermia. Dehydration is difficult to diagnose due to baseline wasting and skin elasticity loss. Severely malnourished children fail to mount a fever or leukocytosis during severe sepsis. |
| Differentials | Hepatic Failure: No history of jaundice, clay-colored stools, or bleeding tendency. Severe Stunting (Endocrine): No history of preserved subcutaneous fat with short stature. | Rules out primary hepatic cirrhosis causing hypoalbuminemia. Differentiates acute wasting from isolated endocrine growth hormone deficiency. |
Other Relevant History
- Birth & Gestational History: Birth weight, gestational age (preterm / IUGR status).
- Feeding & Dietary History: Detailed 24-hour dietary recall. Calculate calories and protein strictly against Ideal Body Weight (IBW) for chronological age or 50th percentile weight-for-height.
- Immunization History: Check specifically for Measles / MR vaccine and Vitamin A supplementation.
- Developmental History: Assess gross motor and social developmental milestones.
- Socioeconomic & Sanitation: Kuppuswamy / BG Prasad scale, access to safe drinking water, open defecation.
History Summary
"Master/Miss `Patient Name`, a `Age` old `male/female` child, `Birth Order` born of a `consanguineous/non-consanguineous` marriage from `City, State`, presented with a `Duration` history of failure to thrive, progressive severe wasting of muscles and body fat, listlessness, bilateral pedal edema of `Duration in days` duration, and recent onset of loose stools and poor feeding, in the absence of chronic cough, TB contact, convulsions, or gross hematuria.
In view of the severe wasting, bilateral pitting pedal edema, and apathy, I would like to consider a provisional diagnosis of Severe Acute Malnutrition (SAM with Marasmic-Kwashiorkor presentation), currently complicated by `Dehydrating Diarrhea / Hypothermia / Anorexia`, requiring immediate inpatient stabilization at the Nutritional Rehabilitation Center (NRC)."
General & Head-to-Toe Examination
- Child Behavioral State: Document Prechtl state (e.g., Prechtl State 2: drowsy, listless, miserable on disturbance, severe apathy).
- Vitals: Heart rate, respiratory rate, blood pressure, temperature (check for hypothermia $<36.0^\circ\text{C}$), and capillary refill time (CRT).
- Anthropometry (Mandatory SAM Triad):
- Weight-for-Length/Height (WFH): Calculate Z-score ($< -3\text{ SD}$ diagnostic).
- Mid-Upper Arm Circumference (MUAC): Check with Shakir tape in children 6-59 months ($< 11.5\text{ cm}$ / Red Zone diagnostic).
- Bilateral Pitting Pedal Edema: Check dorsum of feet for 3 seconds (Grade +, ++, or +++ diagnostic).
- General Physical Findings:
- Facies: "Old man facies" (loss of buccal fat pads) or moon facies (kwashiorkor).
- Muscle & Fat Wasting: Loss of fat over axillae, groins, gluteal folds ("baggy pants").
- Skin Changes: Flaky paint / crazy pavement dermatosis, xerosis, petechiae.
- Hair Changes: Sparse, brittle, hypopigmented hair with flag sign.
- Nutritional Stigmata: Bitot spots, corneal xerosis (Vit A), angular stomatitis (Vit B2), spongy bleeding gums (Vit C), rachitic rosary (Vit D), severe pallor (Iron/Folate).
Systemic Examination
Abdomen
- Scaphoid or distended with thin abdominal wall; palpate liver span (enlarged soft smooth liver indicates hepatic steatosis / fatty liver of kwashiorkor); spleen not palpable; bowel sounds normal or hyperactive.
Cardiovascular & Respiratory Systems
- Low-volume pulse, distant heart sounds; alert: high risk of acute heart failure with excess fluids; clear breath sounds or crackles of pneumonia.
Central Nervous System
- Apathy, generalized hypotonia, hyporeflexia; check for signs of meningism or encephalopathy.
Final Summary & Diagnosis
"A `Age` old `male/female` child presenting with severe wasting, bilateral pedal edema, and poor feeding, with anthropometry demonstrating Weight-for-Length `< -3 SD`, MUAC `MUAC in cm`, and bilateral pitting pedal edema, accompanied by hepatomegaly (fatty liver) and dermatosis.
My final diagnosis is Severe Acute Malnutrition (SAM - Marasmic-Kwashiorkor) with `Medical Complications: Anorexia / Failed Appetite Test / Dehydration / Hypothermia`, requiring admission to the Nutritional Rehabilitation Center for WHO 10-step inpatient management."
