⏳ Case-based MCQ | #Case_344
〰〰〰〰〰〰〰〰〰〰〰〰〰〰
A 12‐year‐old boy is brought to the clinic because of a several monthhistory of strange behavior. According to his parents, the boy occasionally starts staring and does not respond at all. He also has tears in his eyes during these events. These episodes last several seconds and he then returns to his baseline. He has not sustained any head trauma andis on no medications.

⏳ Case-based MCQ | #Case_343 | #answer
〰〰〰〰〰〰〰〰〰〰〰〰〰〰
✅ B
This patient has mixed metabolic acidosis and metabolic alkalosis (choice B) despite the normal values of pH, [HCO‐3], PaCO2. The evidence supporting an acid base disturbance in this patient is the highplasma anion gap (PAG) of 21mmol/L (calculated as: [Na] – [HCO‐3] – [Cl]). The discrepancy between DPAG and D[HCO‐3] indicates high anion gap metabolic acidosis. DPAG and D[HCO‐3] are calculated by subtracting the normal values of these parameters from the prevailing patient values. DPAG is thus, 11mmol/L (21 – 10) and D[HCO‐3] is ‐3mmol/L (24 – 27). This means that there are 8mmol /L of unmeasured anions and indicates existence of high anion gap metabolic acidosis. These unmeasured anions are most likely ketoacids from starvation that accompanies Hyperemesis Gravidarum. Indeed, ketoacidosis and kentonuria are essential criteria for diagnosis of this disorder. Metabolic alkalosis is suggested by the normal pH in the presence of metabolic acidosis (due to ketoacids) and this is further supported by the fact that the patient has severe vomiting which is known to cause metabolic alkalosis. When vomiting stops in this patient and before she starts normal feeding, pH may transiently decrease because metabolic acidosis will then be uncovered. On the other hand if this patient is fed parenterally and vomiting persists pH may transiently increase because metabolic alkalosis will then be uncovered.
⚠ She has normal acid base status (choice A) is an incorrect statement. The high plasma anion gap (PAG) and the discrepancy between DPAG and D[HCO‐3] indicates an abnormal acid base status.
⚠ She has mixed metabolic acidosis and respiratory alkalosis (choice C) is not correct. If this patient had mixed metabolic acidosis and respiratory alkalosis, PaCO2 would not be normal. By definition, respiratory alkalosis results from low PaCO2 due to excessive washout of CO2 from the body. If this patient had an isolated or simple metabolic acidosis (ketoacidosis from starvation and she is not vomiting) and normal respiratory system, respiratory compensation would bring PaCO2 down and raise the pH back towards normal. If she had respiratory alkalosis on top of metabolic acidosis, PaCO2 would be brought down even more that what usually occurs during ordinary respiratory compensation to metabolic acidosis and pH might return all the way back to normal.
⚠ She has mixed metabolic alkalosis and respiratory acidosis (choice D) is not correct. If this patient had mixed metabolic alkalosis and respiratory acidosis PaCO2 would not be normal. By definition, respiratory acidosis results from high PaCO2 due to retention of CO2 in body fluids. If this patient had an isolated or simple metabolic alkalosis (due to vomiting but no ketoacidosis) and normal respiratory system, respiratory compensation would raise PaCO2 and decrease the pH back towards normal. If she had respiratory acidosis on top of metabolic alkalosis, PaCO2 would be raised even more that what would occur during ordinary respiratory compensation to metabolic alkalosis and pH might return all the way back to normal.
⚠ Her acid base status is unclassifiable and needs further evaluation (choice E) is not correct. Obviously, the acid base status of this patient is classifiable and is classified as mixed metabolic acidosis and metabolic alkalosis.
🔖 Key point:
In a patient with Hyperemesis Gravidarum, normal values of pH, D [HCO‐3] and PaCO2 do not excludeacid base disturbance. The anion gap should be calculated to look for concealed acid base disturbances.

〰〰〰〰〰〰〰〰〰〰〰〰〰〰
A primigravida in her 7th gestational week was brought to hospital with severe nausea and vomiting of three days duration. No other symptoms could be elicited. Physical examination is as follows: pulse rate 108 bpm, respiratory rate 17/min, blood pressure 98/58 mmHg and body temperature 37.1°C; diminished skin turgor and dry oral mucous membrane and the rest of physical examination was normal. With appropriate work‐up the diagnosis of Hyperemesis Gravidarum was established. Some of her lab results are as follows:
pH 7.42
[HCO‐3] 24mmol/L
PaCO2 39mmHg
Serum sodium 140mmol/L
Serum potassium 3.7mmol/L
Serum chloride 95mmol/L

Patients with Down syndrome have a 15% increased incidence of atlantoaxial instability (AAI). There is a resulting risk of spinal cord injury in these patients. Certain sports are contraindicated for those with AAI, including gymnastics, and radiographs should be obtained prior to participation.
