Paediatric core condition- 4 Flashcards

1
Q

Intestinal obstruction

A

Intestinal obstruction is where a physical obstruction prevents the flow of faeces through the intestines. This blockage will lead to a back-pressure through the gastrointestinal system, causing vomiting. It also causes absolute constipation, where the patient is unable to pass stools or wind.

Q

Causes and diagnosis of intestinal obstruction

A

Causes= Meconium ileus, Hirschsprungs disease, Oesophageal atresia, Duodenal atresia, Intussusception, Imperforate anus, Malrotation of the intestines with a volvulus, strangulated hernia

Diagnosis= Abdominal xray. This may show dilated loops of bowel proximal to the obstruction and collapsed loops of bowel distal to the obstruction. There will also be absence of air in the rectum.

A
  • Persistent vomiting. This may be bilious, containing bright green bile.
  • Abdominal pain and distention
  • Failure to pass stools or wind
  • Abnormal bowel sounds. These can be high pitched and “tinkling” early in the obstruction and absent later.

Q

Management of intestinal obstruction

A

Needs to be referred to a paediatric surgical unit as an emergency. Initial management involves making them nil by mouth and inserting a nasogastric tube to help drain the stomach and stop the vomiting. They will also require IV fluids to correct any dehydration and electrolyte imbalances, and keep them hydrated while waiting for definitive management of the underlying cause.

Q

Irritable hip i.e. transient synovitis pathophysiology

A

Temporary irritation and inflammation in the synovial membrane of the joint. Most common cause of hip pain in children aged 3-10 years, often associated with viral upper respiratory tract infections. Children with transient synovitis typically do not have a fever. Children with joint pain and a fever need urgent management for septic arthritis.

Q

Transient synovitis: NICE guidelines

A

Children aged 3 – 9 years with symptoms suggestive of transient synovitis may be managed in primary care if the limp is present for less than 48 hours and they are otherwise well, however they need clear safety net advice to attend A&E immediately if the symptoms worsen or they develop a fever. They should also be followed up at 48 hours and 1 week to ensure symptoms are improving and then fully resolve.

  • Treated with chemotherapy, with treatment survival is 5-6 years
27
Q

Chronic lymphoblastic leukaemia

A
  • Most common in males over 60 due to the proliferation of functionally incompetent malignant B cells
  • Normally asymptomatic but can present with non-tender lymphadenopathy, hepatosmegaly, weight loss, night sweats and fever
  • Diagnosis= The most common initial blood result is an incidental lymphocytosis. Subsequent blood film shows smudge cells, which are cells damaged as they lack a cytoskeletal protein. Also use flow cytometry and bone marrow biopsy
  • Treatment: chemotherapy
28
Q

Risk factors for leukaemia= syndromes

A

Downs syndrome, Kleinfelters syndrome, Noonan syndrome, Fanconi’s anaemia

29
Q

Pyloric stenosis

A

Pyloric stenosis typically presents in the second to fourth weeks of life with vomiting, although rarely may present later up to four months. It is caused by hypertrophy of the circular muscles of the pylorus. More common in males, first borns and with family history

30
Q

  • constipation and dehydration may also be present
  • a palpable mass may be present in the upper abdomen
  • hypochloraemic, hypokalaemic alkalosis due to persistent vomiting
  • Failure to thrive, if examined after feeding you can see peristalsis in the abdomen
31
Q

Pyloric stenosis: diagnosis and management

A

Diagnosis is most commonly made by ultrasound.

Management involves laparoscopic pyloromyotomy (known as Ramstedt’s operation). Until the procedure should be nil by mouth and kept on IV fluids. Severely dehydrated babaies may require acute fluid resuscitation.

* Metaphyseal corner fractures (occur due to a twisting/pulling motion on a limb)
* Finger fractures
* Clavicle fractures
* Bloods to exclude organic causes such as clotting disorders or haematological malignancy

36
Q

Non-accidental injury: management

A
  • Always inform a senior if you suspect non-accidental injury. Every workplace will additionally have a named safeguarding lead you can contact
  • Admit the child for safeguarding while investigations continue. Ensure other children at home are also safe.
  • Management of injuries
  • Clear and thorough documentation is vitally important
  • Contact social care to see if the child/caregiver is known to them already

46
Q

SGA: screening

A

Any woman with one major risk factor will be referred for serial growth scans, which are essential to monitor and diagnose SGA. If a woman has three or more minor risk factors, she should be referred for uterine artery Doppler at 20-24 weeks gestation. Women with abnormal uterine artery Doppler should also be referred for serial growth scans.
