A 15-year-old girl is admitted to hospital following a ruptured ectopic pregnancy. She comes from a family of Jehovah's Witnesses. Her haemoglobin on admission is 6.7 g/dl. She consents to a blood transfusion but her mother refuses. What is the most appropriate course of action?
Your Answer: Give the blood transfusion
Explanation:People aged 16 or over are entitled to consent to their own treatment. This can only be overruled in exceptional circumstances. Children under the age of 16 can consent to their own treatment if they’re believed to have enough intelligence, competence and understanding to fully appreciate what’s involved in their treatment. This is known as being Gillick competent.Otherwise, someone with parental responsibility can consent for them.This could be:the child’s mother or fatherthe child’s legally appointed guardiana person with a residence order concerning the childa local authority designated to care for the childa local authority or person with an emergency protection order for the child.Giving the blood transfusion is therefore both clinically and ethically the right course of action.Jehovah’s Witnesses frequently carry a signed and witnessed Advance Decision Document listing the blood products and autologous procedures that are, or are not, acceptable to them It is appropriate to have a frank, confidential discussion with the patient about the potential risks of their decision and the possible alternatives to transfusion, but the freely expressed wish of a competent adult must always be respected.

A 9 year old girl who has recently undergone a laparoscopic appendicectomy for a perforated appendix develops a swinging temperature of 38.8 C while on admission. What is next step in her management?
Your Answer: Arrange for an ultrasound scan to look for intra-abdominal collection
Explanation:Children who present with ruptured appendices are at increased risk of intra abdominal collections or abscesses. A swinging temperature is the first clue in indicating an intra abdominal abscess in a patient who had recently undergone surgery for a perforated appendix. The best course of action is therefore to get an ultrasound of the fluid collection before proceeding to rule out any other complication.

A 15-year-old boy presents to the physician complaining of malaise and inability to participate in physical activities due to exhaustion. His vitals, including the blood pressure are within the normal range and the labs are as follows: sodium 145 mmol/lpotassium 2.8 mmol/lbicarbonate 30 mmol/lchloride 83 mmol/l (95-107)magnesium 0.5 mmol/l (0.75-1.05)glucose 5.0 mmol/lrenin 5.1 mmol/ml per h (3-4.3)aldosterone 975 mmol/l (330-830)urea 5.2 mmol/l. What is the most likely diagnosis?
Your Answer: Chronic fatigue syndrome
Correct Answer: Gitelman’s syndrome
Explanation:Gitelman syndrome is a kidney disorder that causes an imbalance of charged atoms (ions) in the body, including ions of potassium, magnesium, and calcium.The signs and symptoms of Gitelman syndrome usually appear in late childhood or adolescence. Common features of this condition include painful muscle spasms (tetany), muscle weakness or cramping, dizziness, and salt craving. Also common is a tingling or prickly sensation in the skin (paraesthesia), most often affecting the face. Some individuals with Gitelman syndrome experience excessive tiredness (fatigue), low blood pressure, and a painful joint condition called chondrocalcinosis. Studies suggest that Gitelman syndrome may also increase the risk of a potentially dangerous abnormal heart rhythm called ventricular arrhythmia.

A 12-year-old girl presents with constant dripping of urine despite being able to void a full volume bladder. An ultrasound scan shows bilaterally enlarged kidneys. What is the most probable diagnosis for this patient?
Your Answer: Horseshoe kidney
Correct Answer: Duplex kidney with ectopic ureter
Explanation:The most probable diagnosis for this patient would be a duplex kidney with an ectopic ureter inserting below the bladder neck. Rationale: The Weigert-Myer law states that the upper moiety ureter inserts inferior and medial to the lower moiety ureter. Other options:- Horseshoe kidney would display as a single pelvic kidney on an ultrasound scan.- Ureterocele would be a cystic lesion within the bladder or may prolapse at birth. – Continence should not be affected by polycystic kidney disease. – The overactive bladder would cause frequency and urgency, neither of which is mentioned in the history.

Question 8

A baby born at 25 weeks gestation around 24 hours ago is reported to be in a critical state. Birth weight is 550g and the baby shows a poor respiratory effort. The membranes ruptured just prior to the delivery with no signs of maternal fever or sepsis. The infant received no antenatal steroids. After delivery, the neonate was subsequently intubated, resuscitated and given a dose of Curo surf. he was extubated onto CPAP within 6 hours. UVC and UAC access was established and benzylpenicillin and gentamicin were administered. Small amounts of maternal breast milk were given for mouthcare. The baby's cardiovascular system was stable and early ABG samples were within acceptable ranges. At 24 hours of age the baby deteriorates with numerous desaturations and bradycardias requiring reintubation. First gas following reintubation shows pH 7.19, CO2 8.6 kPa, BE -10. Oxygen requirement is 60%. FBC is unremarkable. The baby is cool peripherally and central CRT is 3-4 seconds. There is a loud machinery murmur. Abdominal radiograph shows a football sign. What is the most likely cause of the baby's deterioration?
Your Answer: Group B streptococcus infection
Correct Answer: Spontaneous intestinal perforation
Explanation:Spontaneous intestinal perforation (SIP) of the new-born, also referred to as isolated perforation or focal intestinal perforation (FIP) of the new-born, is a single intestinal perforation that is typically found at the terminal ileum. SIP occurs primarily in preterm infants with very low birth weight (VLBW, birth weight <1500 g) and extremely low birth weight (ELBW, birth weight <1000 g), umbilical catheter placement, maternal drug use and twin-to-twin transfusion syndrome. SIP is a separate clinical entity from necrotizing enterocolitis, the most severe gastrointestinal complication of preterm infants.

A 16-year-old male presents to the clinic with a month-long history of headaches, which are worse in the morning and when lying down. There is no significant past medical history and he is not currently taking any medications. Eye examination reveals left sided homonymous hemianopia with macular sparing. A lesion is most likely suspected in which of the following sites?
Your Answer: Right sided optic tract
Explanation:Homonymous hemianopia (HH) is a visual field defect involving either two right or the two left halves of the visual field of both eye. It results from the damage of the visual pathway in its suprachiasmatic part. The causes of HH include stroke, brain tumours, head injuries, neurosurgical procedures, multiple sclerosis and miscellaneous conditions. HH result in a severe visual impairment and affect a variety of cognitive visual functions. Patients with HH frequently have difficulties with reading and scanning scenes in sufficiently rapid fashion to make sense of things as a whole. They stumble, fall or knock objects in their surroundings, since they cannot see them and they are frequent surprised that somebody or something suddenly appeared in their visual field. The prognosis of visual field deficit recovery is highly variable and depends on the cause and severity of brain nd optic pathway injury.
