Common Neonatal Gastrointestinal Disorders

There are several common gastrointestinal disorders that can affect newborns. These include pyloric stenosis, necrotising enterocolitis (NEC), congenital duodenal atresia, Hirschsprung’s disease, and tracheoesophageal fistula (TOF).

Pyloric stenosis is characterised by hypertrophy of the circular pyloric muscle, and typically presents with non-bilious, projectile vomiting in the third or fourth week of life. Constipation and dehydration may also occur, and biochemistry may show hypokalaemic metabolic alkalosis. Boys are more likely to be affected, especially if born into a family with affected girls.

NEC is a condition primarily seen in premature infants, where portions of the bowel undergo necrosis. Symptoms include bilious vomiting, distended abdomen, and bloody stools, with late signs including bowel perforation and multi-organ failure.

Congenital duodenal atresia is a congenital absence or complete closure of a portion of the lumen of the duodenum, and presents with bile-stained vomiting, abdominal distension, and inability to pass meconium.

Hirschsprung’s disease is characterised by the failure of ganglion cells to migrate into the hindgut, leading to functional intestinal obstruction. Symptoms include abdominal distension, bile-stained vomiting, and failure to pass meconium.

TOF refers to a communication between the trachea and oesophagus, usually associated with oesophageal atresia. Symptoms include choking, coughing, and cyanosis during feeding, excess mucus, and recurrent lower respiratory tract infections. Other congenital anomalies may also be present.

Overall, early recognition and management of these neonatal gastrointestinal disorders is crucial for optimal outcomes.

Patients who have AF and stable CVD are typically prescribed anticoagulants while antiplatelets are discontinued. This is because such patients are at risk of stroke, as indicated by their CHADS-VASC score, which takes into account factors such as age, hypertension, and cardiovascular disease. Therefore, the patient in question needs to be treated accordingly. In this case, the patient should discontinue their antiplatelet medication and switch to oral anticoagulant monotherapy.

Managing Combination Antiplatelet and Anticoagulant Therapy

With the rise of comorbidity, it is becoming increasingly common for patients to require both antiplatelet and anticoagulant therapy. However, this combination increases the risk of bleeding and may not be necessary in all cases. While there are no guidelines to cover every scenario, a recent review in the BMJ offers expert opinion on how to manage this situation.

For patients with stable cardiovascular disease who require an anticoagulant, it is recommended that they receive antiplatelet therapy as well. However, if the patient has an indication for an anticoagulant, such as atrial fibrillation, it is best to prescribe anticoagulant monotherapy without the addition of antiplatelets.

In patients who have experienced an acute coronary syndrome or undergone percutaneous coronary intervention, there is a stronger indication for antiplatelet therapy. Typically, patients are given triple therapy (two antiplatelets and one anticoagulant) for four to six months after the event, followed by dual therapy (one antiplatelet and one anticoagulant) for the remaining 12 months. However, the stroke risk in atrial fibrillation varies according to risk factors, so there may be variation in treatment from patient to patient.

For patients who develop venous thromboembolism while on antiplatelets, they will likely be prescribed anticoagulants for three to six months. An ORBIT score should be calculated to determine the risk of bleeding. Patients with a low risk of bleeding may continue taking antiplatelets, while those with an intermediate or high risk of bleeding should consider stopping them.

Overall, managing combination antiplatelet and anticoagulant therapy requires careful consideration of the patient’s individual circumstances and risk factors.

A decrease in albumin levels is frequently observed after an acute phase response.

Acute phase proteins are a group of proteins that are produced by the liver in response to inflammation or infection. These proteins are involved in various physiological processes such as immune response, blood clotting, and iron metabolism. Examples of acute phase proteins include CRP, procalcitonin, ferritin, fibrinogen, alpha-1 antitrypsin, caeruloplasmin, serum amyloid A, serum amyloid P component, haptoglobin, and complement.

During the acute phase response, the liver decreases the production of other proteins known as negative acute phase proteins. These proteins include albumin, transthyretin, transferrin, retinol binding protein, and cortisol binding protein. The levels of acute phase proteins, particularly CRP, are commonly measured in acutely unwell patients. Elevated levels of CRP are indicative of inflammation or infection, and levels greater than 150 at 48 hours post-surgery suggest the development of complications.

It is important to note that while acute phase proteins play a significant role in humans, some of these proteins, such as serum amyloid P component, have a more significant role in other mammals like mice. Overall, the production of acute phase proteins is a crucial part of the body’s response to inflammation or infection, and monitoring their levels can aid in the diagnosis and management of various medical conditions.

To confirm or rule out ectopic pregnancy, the recommended investigation is transvaginal ultrasound. This is because it provides clearer images of the uterus, ovaries, and endometrium, making it more effective in detecting ectopic pregnancies compared to transabdominal scans. While serum Beta-HCG levels are helpful in managing ectopic pregnancies, a single test cannot completely rule out the possibility. Pregnant women are generally advised against undergoing CT scans and abdominal X-rays.

Ectopic pregnancy is a serious condition that requires prompt investigation and management. Women who are stable are typically investigated and managed in an early pregnancy assessment unit, while those who are unstable should be referred to the emergency department. The investigation of choice for ectopic pregnancy is a transvaginal ultrasound, which will confirm the presence of a positive pregnancy test.

There are three ways to manage ectopic pregnancies: expectant management, medical management, and surgical management. The choice of management will depend on various criteria, such as the size of the ectopic pregnancy, whether it is ruptured or not, and the patient’s symptoms and hCG levels. Expectant management involves closely monitoring the patient over 48 hours, while medical management involves giving the patient methotrexate and requires follow-up. Surgical management can involve salpingectomy or salpingotomy, depending on the patient’s risk factors for infertility.

Salpingectomy is the first-line treatment for women with no other risk factors for infertility, while salpingotomy should be considered for women with contralateral tube damage. However, around 1 in 5 women who undergo a salpingotomy require further treatment, such as methotrexate and/or a salpingectomy. It is important to carefully consider the patient’s individual circumstances and make a decision that will provide the best possible outcome.

Screening for Hepatocellular Carcinoma: Recommended Tests and Intervals

Regular screening for hepatocellular carcinoma (HCC) is recommended in high-risk patients. Abdominal ultrasound (US) is the primary screening tool, with 6-month intervals for follow-up if a lesion of < 1 cm is detected. If there is no growth over 1-2 years, routine 6-monthly surveillance can continue. Alpha-fetoprotein (AFP) levels may be used in conjunction with US, but are not reliable on their own. A triphasic contrast computed tomography (CT) scan is recommended every two years for high-suspicion cases. This article provides an overview of the recommended tests and intervals for HCC screening.

In the case of a non-shockable rhythm, it is crucial to administer adrenaline as soon as possible according to the ALS protocol. This should be done immediately and during alternate cycles. However, if the rhythm is shockable, adrenaline should be given after the third shock and then during alternate cycles. Amiodarone should be administered after the third shock, and a second dose may be considered after five shocks. Therefore, the other options are not appropriate.

The 2015 Resus Council guidelines for adult advanced life support outline the steps to be taken when dealing with patients with shockable and non-shockable rhythms. For both types of patients, chest compressions are a crucial part of the process, with a ratio of 30 compressions to 2 ventilations. Defibrillation is recommended for shockable rhythms, with a single shock for VF/pulseless VT followed by 2 minutes of CPR. Adrenaline and amiodarone are the drugs of choice for non-shockable rhythms, with adrenaline given as soon as possible and amiodarone administered after 3 shocks for VF/pulseless VT. Thrombolytic drugs should be considered if a pulmonary embolus is suspected. Atropine is no longer recommended for routine use in asystole or PEA. Oxygen should be titrated to achieve saturations of 94-98% following successful resuscitation. The Hs and Ts should be considered as potential reversible causes of cardiac arrest.

Treatment Options for Gastric Ulcers

Gastric ulcers can be caused by long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) and can lead to severe symptoms requiring hospitalization. Treatment options for gastric ulcers include intravenous proton pump inhibitors (PPIs) followed by long-term oral PPIs. A repeat gastroscopy is usually carried out to ensure that the ulcer has healed. In cases where the ulcer has perforated or is malignant, a partial gastrectomy may be indicated. Retesting for H. pylori may be necessary if the patient had previously tested positive. Adrenalin injection is only indicated for bleeding gastric ulcers. Placing the patient nil by mouth is not necessary for healing the ulcer.

Breastfeeding mothers should avoid taking aspirin as it may increase the risk of Reye’s syndrome. High doses of aspirin can also affect platelet function and cause hypoprothrombinaemia in infants with low vitamin K stores. However, paracetamol is safe to use for pain relief during breastfeeding. Anti-emetics such as cyclizine and prochlorperazine are also safe to use while breastfeeding and are unlikely to cause any harm.

Breastfeeding has some contraindications that are important to know, especially when it comes to drugs. Antibiotics like penicillins, cephalosporins, and trimethoprim are safe for breastfeeding mothers, as are endocrine drugs like glucocorticoids (in low doses) and levothyroxine. Epilepsy drugs like sodium valproate and carbamazepine, asthma drugs like salbutamol and theophyllines, and hypertension drugs like beta-blockers and hydralazine are also safe. Anticoagulants like warfarin and heparin, as well as digoxin, are also safe. However, some drugs should be avoided, such as antibiotics like ciprofloxacin, tetracycline, chloramphenicol, and sulphonamides, psychiatric drugs like lithium and benzodiazepines, aspirin, carbimazole, methotrexate, sulfonylureas, cytotoxic drugs, and amiodarone. Other contraindications include galactosaemia and viral infections, although the latter is controversial in the developing world due to the increased risk of infant mortality and morbidity associated with bottle feeding.

Understanding Geographic Tongue: Symptoms, Causes, and Management

Geographic tongue is a common and benign condition that affects the tongue. It is characterized by irregular, smooth, red patches with a white border that resemble a map. While some individuals may experience pain or discomfort, others may not have any symptoms at all. The cause of geographic tongue is unknown, and there is currently no cure. However, symptomatic pain relief and avoidance of certain triggers may help manage the condition.

It is important to differentiate geographic tongue from other oral conditions such as oral candidiasis, oral leukoplakia, and vitamin deficiencies. Oral candidiasis can present with white/yellow plaques that can be easily removed, while oral leukoplakia presents with painless white plaques that cannot be easily scraped away and may be pre-malignant. Vitamin deficiencies such as B12 and C can also cause oral symptoms.

Overall, geographic tongue is a harmless condition that primarily affects females. While it may cause discomfort for some individuals, it does not pose any serious health risks. If you are experiencing symptoms of geographic tongue, it is recommended to seek advice from a healthcare professional for proper diagnosis and management.

Before administering the vaccine, it is crucial to conduct a tuberculin skin test to rule out any previous exposure to tuberculosis.

The BCG Vaccine: Who Should Get It and How It’s Administered

The Bacille Calmette-Guérin (BCG) vaccine is a vaccine that provides limited protection against tuberculosis (TB). In the UK, it is given to high-risk infants and certain groups of people who are at risk of contracting TB. The vaccine contains live attenuated Mycobacterium bovis and also offers limited protection against leprosy.

The Greenbook provides guidelines on who should receive the BCG vaccine. It is recommended for all infants living in areas of the UK where the annual incidence of TB is 40/100,000 or greater, as well as infants with a parent or grandparent who was born in a country with a high incidence of TB. The vaccine is also recommended for previously unvaccinated tuberculin-negative contacts of cases of respiratory TB, new entrants under 16 years of age who were born in or have lived for a prolonged period in a high-risk country, healthcare workers, prison staff, staff of care homes for the elderly, and those who work with homeless people.

Before receiving the BCG vaccine, any person being considered must first be given a tuberculin skin test, except for children under 6 years old who have had no contact with tuberculosis. The vaccine is given intradermally, normally to the lateral aspect of the left upper arm. It can be given at the same time as other live vaccines, but if not administered simultaneously, there should be a 4-week interval.

There are some contraindications for the BCG vaccine, including previous BCG vaccination, a past history of tuberculosis, HIV, pregnancy, and a positive tuberculin test (Heaf or Mantoux). It is not given to anyone over the age of 35, as there is no evidence that it works for people of this age group.
