Diagnosis of CKD and Hypertension: NICE Guidelines

The National Institute for Health and Care Excellence (NICE) has provided guidelines for the diagnosis of chronic kidney disease (CKD) and hypertension. To diagnose CKD, more than one estimated glomerular filtration rate (eGFR) reading below 60 is required over a period of three months. Similarly, hypertension should not be diagnosed based on a single blood pressure reading, but rather through ambulatory or home blood pressure monitoring. Acute kidney injury is characterized by a significant increase in serum creatinine or oliguria, and eGFR is not a reliable indicator for its diagnosis. NICE also recommends using eGFRcystatinC to confirm or rule out CKD in individuals with an eGFR of 45-59 ml/min/1.73 m2, sustained for at least 90 days, and no proteinuria or other markers of kidney disease.

Factors to Consider in Prostate Cancer

Ethnicity is a significant factor to consider when discussing prostate cancer. The incidence of prostate cancer varies geographically, with the highest rates found in men of black ethnic group and the lowest rates in Chinese men. Age is another important factor, as prostate cancer is rare in men under 50 years old, with the majority of diagnoses made in patients over 65. Family history is also a risk factor, particularly in younger men. Prostate cancer can cluster within families, and having a first-degree relative under 70 with prostate cancer can double a patient’s relative risk of developing the disease. Finally, diet is another factor to consider, as a diet rich in red meat and dairy products has been linked to an increased risk of prostate cancer. By taking these factors into account, healthcare professionals can better assess a patient’s risk of developing prostate cancer and provide appropriate screening and treatment.

Renal Complications in Rheumatoid Arthritis Treatment

Rheumatoid arthritis is a chronic autoimmune disease that affects the joints and can lead to disability. The use of gold, penicillamine, and non-steroidal anti-inflammatory agents as disease-modifying drugs in the treatment of rheumatoid arthritis can result in renal complications. Membranous glomerulonephritis is a common complication that occurs due to the widespread thickening of the glomerular basement membrane. Immunofluorescence reveals granular deposits of immunoglobulin and complement. Methotrexate, another drug used in the treatment of rheumatoid arthritis, can also be toxic to the kidney in large doses. However, such doses are unlikely in patients with rheumatoid arthritis. It is important for healthcare providers to monitor renal function in patients receiving these medications to prevent renal complications.

Patients with stress incontinence who do not respond to pelvic floor muscle exercises and refuse surgical intervention may be prescribed duloxetine as a second-line treatment, according to NICE guidelines. If conservative treatments fail or the patient desires further management, referral to a urogynaecologist, gynaecologist, or urologist for assessment and surgical management may be considered. For urgency incontinence, anticholinergic drugs such as darifenacin, oxybutynin, and tolterodine are typically used as first-line treatments, while mirabegron may be prescribed if antimuscarinic drugs are ineffective, not tolerated, or contraindicated.

Urinary incontinence is a common condition that affects approximately 4-5% of the population, with elderly females being more susceptible. There are several risk factors that can contribute to the development of urinary incontinence, including advancing age, previous pregnancy and childbirth, high body mass index, hysterectomy, and family history. The condition can be classified into different types, such as overactive bladder, stress incontinence, mixed incontinence, overflow incontinence, and functional incontinence.

Initial investigation of urinary incontinence involves completing bladder diaries for at least three days, performing a vaginal examination to exclude pelvic organ prolapse, and conducting urine dipstick and culture tests. Urodynamic studies may also be necessary. Management of urinary incontinence depends on the predominant type of incontinence. For urge incontinence, bladder retraining and bladder stabilizing drugs such as antimuscarinics are recommended. For stress incontinence, pelvic floor muscle training and surgical procedures may be necessary. Duloxetine, a combined noradrenaline and serotonin reuptake inhibitor, may also be offered to women who decline surgical procedures.

In summary, urinary incontinence is a common condition that can be caused by various risk factors. It can be classified into different types, and management depends on the predominant type of incontinence. Initial investigation involves completing bladder diaries, performing a vaginal examination, and conducting urine tests. Treatment options include bladder retraining, bladder stabilizing drugs, pelvic floor muscle training, surgical procedures, and duloxetine.

Understanding PSA Testing and Biopsy Risks for Prostate Cancer

Prostate-specific antigen (PSA) testing is a common screening tool for prostate cancer. However, it should not be measured without a digital examination. If the screen is positive, a biopsy may be needed, which carries risks such as infection, haematuria, and haematospermia, as well as a small mortality risk. It’s important to note that about one-third of men with a raised PSA will have prostate cancer, but biopsies can miss about one-fifth of cancers.

When counselling a man for PSA testing, it’s crucial to explain the potential risks and benefits. Urgent referral is not necessary if the prostate is simply enlarged and the PSA is within the age-specific reference range. The Prostate Cancer Risk Management Programme recommends age-specific cut-off PSA measurements, with a threshold of 3.5 ng/ml for men under 50, over 3.5 ng/ml for men aged 50-59, 4.0 ng/ml for men aged 60-69, and clinical judgement for men aged 70 and over.

Understanding the nuances of PSA testing and biopsy risks can help men make informed decisions about their prostate health.

Urgent Admission for a Patient with Acute Glomerulonephritis

Explanation:

A patient presenting with nephritic syndrome, including haematuria, oliguria, hypertension, and oedema, is likely suffering from acute glomerulonephritis, possibly post-streptococcal. This condition can lead to acute kidney injury and requires urgent investigation. Therefore, routine referral to paediatric nephrologists or urologists is not appropriate in this case. Instead, the patient needs to be admitted to the hospital for urgent investigation and management. While follow-up with paediatric nephrologists may be necessary, the acute presentation with hypertension and oedema requires immediate attention. A two-week rule referral for suspected malignancy is not indicated in this case.

Urinary tract infections (UTIs) are common in adults and can affect different parts of the urinary tract. Lower UTIs are more common and can be managed with antibiotics. For non-pregnant women, local antibiotic guidelines should be followed, and a urine culture should be sent if they are aged over 65 years or have visible or non-visible haematuria. Trimethoprim or nitrofurantoin for three days are recommended by NICE Clinical Knowledge Summaries. Pregnant women with symptoms should have a urine culture sent, and first-line treatment is nitrofurantoin, while amoxicillin or cefalexin can be used as second-line treatment. Asymptomatic bacteriuria in pregnant women should also be treated with antibiotics. Men with UTIs should be offered antibiotics for seven days, and a urine culture should be sent before starting treatment. Catheterised patients should not be treated for asymptomatic bacteria, but if they are symptomatic, a seven-day course of antibiotics should be given, and the catheter should be removed or changed if it has been in place for more than seven days. For patients with signs of acute pyelonephritis, hospital admission should be considered, and local antibiotic guidelines should be followed. The BNF recommends a broad-spectrum cephalosporin or a quinolone for 10-14 days for non-pregnant women.

Understanding Gonorrhoea

Gonorrhoea is a sexually transmitted infection caused by Neisseria gonorrhoeae. It is characterized by purulent urethral discharge and epididymitis. To diagnose gonorrhoea, a Gram stain of the urethral discharge fluid is performed. It is important to trace partners where possible to prevent further spread of the infection.

The treatment of choice for gonorrhoea is Ceftriaxone IM due to increased resistance to fluoroquinolones. Azithromycin 1G orally as a single dose is also recommended. Other combinations are available as alternatives. It is crucial to screen the patient for other sexually transmitted infections, including HIV.

In summary, gonorrhoea is a common sexually transmitted infection that can be easily diagnosed and treated. Early detection and treatment are essential to prevent complications and further spread of the infection.

Undescended Testicles in Infants: Diagnosis and Treatment Options

Undescended testicles, also known as cryptorchidism, is a common condition in male infants where one or both testicles fail to descend into the scrotum. This can lead to potential complications such as infertility and an increased risk of testicular cancer.

The recommended course of action is to refer the infant to paediatric surgery or urology before six months of age. The current recommended timing for surgery is before 12 months of life to preserve the stem cells for subsequent spermatogenesis. However, even with surgical treatment, long-term outcomes remain problematic with impaired fertility and an increased cancer risk.

If one or both testicles are retractile, annual follow-up throughout childhood is advised due to the risk of ascending testis syndrome. Hormone treatment is an option, but it has a lower success rate and more adverse effects compared to surgery.

For cases where a single testis is undescended, a referral to paediatric surgery or urology should be made by six months of age if the testis has not descended. It is important to review the surgical option after 12 months of age.

Early diagnosis and prompt treatment are crucial in managing undescended testicles in infants.

Asymptomatic Bacteriuria in Elderly and Pregnant Women

Asymptomatic bacteriuria is a common condition in elderly and pregnant women. In healthy patients, a pure growth with normal white and red cells doesn’t require treatment unless an invasive urological procedure is planned. However, in pregnant women, it should be treated as it is associated with low birth weight and premature delivery. There is no evidence of long-term harm or benefit from medication in patients with a normal renal tract. It is important to be cautious in apparently asymptomatic men who may have chronic prostatitis.

Public Health England advises against sending urine for culture in asymptomatic elderly individuals with positive dipsticks. Urine should only be sent for culture if there are two or more signs of infection, such as dysuria, fever > 38 °C, or new incontinence. Asymptomatic bacteriuria in the elderly should not be treated as it is very common, and treating it doesn’t reduce mortality or prevent symptomatic episodes. In fact, treating it can increase side effects and antibiotic resistance.
