Urinary tract infections and calculus UTI and renal stones (nepphrolithiasis), bladder stones
Table of contents (toc)
Introduction to UTI
A urinary tract infection (UTI) is an infection in any part of the urinary system, which includes the kidneys, ureters, bladder, and urethra. Most infections involve the lower urinary tract, specifically the bladder and urethra. UTIs are typically caused by bacteria, most commonly Escherichia coli (E. coli), that enter the urinary tract through the urethra and begin to multiply in the bladder.
Symptoms of uti
Symptoms of a UTI can include a strong, persistent urge to urinate, a burning sensation when urinating, passing frequent, small amounts of urine, urine that appears cloudy, or urine that has a strong odor. If the infection spreads to the kidneys, it can cause more severe symptoms, including fever, back pain, and nausea.
Treatment of UTI
UTIs are more common in women than in men, and they can usually be treated effectively with antibiotics.
Introduction to Nephrolithiasis
Nephrolithiasis, commonly known as kidney stones, refers to the formation of hard mineral and salt deposits in the kidneys. These stones can vary in size and may develop when urine becomes concentrated, allowing minerals to crystallize and stick together.
Symptoms of kidney stones
Kidney stones can cause severe pain when they pass through the urinary tract. Symptoms may include intense pain in the back or side, pain during urination, blood in the urine, and sometimes nausea and vomiting. The pain often starts suddenly and may come in waves as the stone moves.
Type of kidney stones
The main types of kidney stones include calcium stones (the most common type), struvite stones (which can form after a urinary tract infection), uric acid stones, and cystine stones (which are rare and usually occur in people with a genetic disorder).
Treatment of kidney stones
Treatment for nephrolithiasis depends on the size and type of stone. Smaller stones may pass on their own with increased fluid intake and pain management, while larger stones may require medical intervention, such as extracorporeal shock wave lithotripsy (ESWL) to break the stone into smaller pieces, or surgical removal. Preventative measures often include dietary adjustments and medications to reduce the risk of recurrence.
Introduction of urethral dilation in female: 30 causes of painful intercourse
Table of Contents(toc)
female genitourinary system
Urethra dilation is a delicate medical procedure done underanesthesis by a urologist or urosurgeon. The procedure is done after careful evaluation and by well trained professionals. Before going deeper into female urethra dilation lets review anatomy of female urethra in brief.
Urethral structure if pathological narrowing of urethra due to different reasons leading to difficulty passing urine and various other symptoms and consequences.
Anatomy of female urethra
Female urethra is tubular musculocutaneous organelle situation in genital region of female that connects bladder to the outer world. The urethra carries urine from bladder to the outside. The flow of urine from bladder is controlled by two valves viz. Internal and external urethral valves. The internal urethral valve is controlled by autonomic nervous system while external is under voluntary control. The overall length of fenale urethra is 4 centimetres or 1.5 inches.

Female urinary system anatomy
Indications of urethral dilation : an introduction
Sexual intercourse after female urrthra dilatation may become difficult rarely. Difficult or painful sexual intercourse is called dysparaunia and it may have several other causes including vaginal infection, dry vagina and many more listed as below.
Painful sexual intercourse or dyspareunia can be because of external genital problems to internal vaginal, uterine or pelvic disorders. Urethra also being near vagina can be the reason for dyspareunia where as other nearby organs and structures can also be part of it. It is also called genitopelvic pain. The causes of painful intercourse can be listed as below:
The flow of urine from bladder is controlled by two valves viz. Internal and external urethral valves. The internal urethral valve is controlled by autonomic nervous system while external is under voluntary control.

Introduction
Fire accidents are common type of injuries that happen in world daily basis.
Shock is a clinical condition that results due to inadequate tissue perfusion.
A critical condition brought on by the sudden drop in blood flow through the body.
May result from trauma, heatstroke, blood loss, an allergic reaction, severe infection, poisoning, severe burns or other causes.
Occurs when the metabolic needs of cells are not met because of inadequate blood flow.
These two topics are very common in emergency managent and should be well taught to medical students, graduates and paramedics.
Signs and symptoms
Cool, clammy skin
Pale or ashen skin
Bluish tinge to lips or fingernails (or gray in the case of dark complexions)
Rapid pulse
Rapid breathing
Nausea or vomiting
Enlarged pupils
Weakness or fatigue
Dizziness or fainting
Changes in mental status or behavior, such as anxiousness or agitation
Burn with Fire
Types of Shock
Hypovolemic Shock

Introduction to BURN
Burns are tissue damage that results from heat, overexposure to the sun or other radiation, or chemical or electrical contact.
Wound with destruction of tissue due to coagulation necrosis.
Causes of burn
Thermal burn/heat burn: dry heat
Scald: moist heat
Electric burn: electricity
Cold burn: frost bite
Chemical burn: strong acid and alkali
Radiation burn: X-rays, Gamma rays
Degree of Burn Classification and grading
First degree – superficial thickness
Second degree – Partial or intermediate thickenss
Third degree – Full thickness
Fourth degree
Management of burn
Remove burning source immediately.
Wrap the patient in a cloth and roll him in the floor.
Immerse 10-15 minutesin water or cool down the burnt part in running water for 15 minutes
Give liquids orally. Provide analgesics and antibiotics.
Do not rupture blister.
TT injection
First-degree burns:
Run cool water over the burn. Don’t apply ice. For sunburns, apply aloe vera gel. For thermal burns, apply antibiotic cream and cover lightly with gauze. You can also take over-the-counter pain medication.
Second-degree burns:
Treatment for second- and first-degree burns is similar.
Stronger antibiotic – such as silver sulfadiazine, to kill bacteria
Elevating the burned area can reduce pain and swelling.
May need dressing to be applied
Third-degree burns:
Third-degree burns can belife-threatening and often require skin grafts. Skin grafts replace damaged tissue with healthy skin from another of the uninjured part of the person’s body.
Wallace Rule of Nine
The Wallace Rule of Nines is a method used to estimate the total body surface area (TBSA) affected by burns. It divides the body into sections, each representing approximately 9% (or multiples thereof) of the total body surface area. The distribution is slightly different for adults and children due to differences in body proportions.
Wallace Rule of Nines for Adults:
Head and Neck: 9%
Each Arm: 9% (4.5% front, 4.5% back)
Each Leg: 18% (9% front, 9% back)
Anterior Torso (Chest and Abdomen): 18%
Posterior Torso (Back and Buttocks): 18%
Perineum/Genitalia: 1%
Wallace Rule of Nines for Children:
Head and Neck: 18% (larger proportion due to the relatively larger head size in children)
Each Arm: 9% (4.5% front, 4.5% back)
Each Leg: 14% (7% front, 7% back; less than in adults because legs are relatively shorter)
Anterior Torso (Chest and Abdomen): 18%
Posterior Torso (Back and Buttocks): 18%
Perineum/Genitalia: 1%
These percentages are used to help us quickly estimate the extent of burns and its severity, which is critical for determining the severity of the injury and guiding treatment decisions, such as fluid resuscitation and transfer to a specialized burn center.
Parkland Formula:
The Parkland formula, also known as the Baxter formula, is used to calculate the amount of fluid required for resuscitation in burn patients within the first 24 hours after injury. The formula is based on the patient’s weight and the total body surface area (TBSA) burned.
Total fluid requirement:4 mL×body weight (kg)×% TBSA burned4 , text{mL} times text{body weight (kg)} times text{% TBSA burned}
4mL×body weight (kg)×% TBSA burned
Administration:
First 8 hours: Administer half of the total fluid requirement.
Next 16 hours: Administer the remaining half.
Example for an Adult:
If an adult weighs 70 kg and has 30% TBSA burns:
Total fluid requirement:4×70×30=8,400 mL4 times 70 times 30 = 8,400 , text{mL}4×70×30=8,400mL
First 8 hours:8,400/2=4,200 mL8,400 / 2 = 4,200 , text{mL}8,400/2=4,200mL
Next 16 hours:4,200 mL4,200 , text{mL}4,200mL
The Parkland formula provides an initial guideline for fluid resuscitation, but ongoing assessment and adjustments based on the patient’s clinical response (urine output, vital signs, etc.) are critical for effective management.

Disulfiram like Reaction (disulfiram-like reaction) Mnemonics
Table of Contents(toc)
Introduction
You can use any of the below mnemonics to remember Disulfiram like Reaction (disulfiram-like reaction).
Disulfiram is a drug commonly used to treat alcohol abude and dependance in outpatient and inpatient settings.
capsules disulfiram
How does disulfiram reaction occur?
The disulfiram reaction occurs when disulfiram inhibits the enzyme aldehyde dehydrogenase, which is responsible for metabolizing acetaldehyde, a toxic intermediate of alcohol metabolism. Normally, alcohol is metabolized in two steps: ethanol is converted into acetaldehyde by alcohol dehydrogenase, and acetaldehyde is further broken down into acetic acid by aldehyde dehydrogenase. Disulfiram blocks the second step, causing acetaldehyde to accumulate in the bloodstream. This accumulation triggers symptoms such as flushing, nausea, vomiting, headache, tachycardia, and hypotension within 10–30 minutes of alcohol ingestion. The severity of symptoms depends on the amount of alcohol consumed and the disulfiram dose.

Disulfiram UK as Antabuse Agent
Many people want to buy antabuse in UK. They want to terminate their habit of abuse of alcohol and other medications.
Availability of Disulfiram in the UK
Disulfiram, commonly known by the brand name Antabuse, is available in the UK as a prescription-only medication used to support the treatment of chronic alcohol dependence. To obtain disulfiram, you must consult a healthcare professional who can assess your suitability for the medication and provide a prescription if appropriate. It’s important to note that disulfiram is typically prescribed as part of a comprehensive treatment plan, including counseling and support, to enhance its effectiveness in promoting abstinence from alcohol.
Disulfiram Dosing and Formulations According to the BNF
The British National Formulary (BNF) provides guidance on the dosing and formulations of disulfiram. Disulfiram is available in oral tablet form, with a common strength being 200 mg. The usual starting dose for adults is 200 mg daily, which may be increased if necessary, up to a maximum of 500 mg daily, depending on individual response and tolerance. It’s crucial that disulfiram is administered under medical supervision, with regular monitoring to assess efficacy and any potential adverse effects. Patients should be informed about the reactions that can occur if alcohol is consumed while taking disulfiram and advised to avoid all sources of alcohol, including those found in certain foods and medications.
Disulfiram Implants in the UK
Disulfiram implants are an alternative method of delivering the medication, involving the surgical insertion of disulfiram pellets under the skin. This method provides a sustained release of the drug over a period, potentially improving adherence by eliminating the need for daily oral dosing. In the UK, disulfiram implants are not widely available and are considered an off-label treatment option. Some private clinics may offer this service; however, it’s essential to approach such treatments with caution. The efficacy and safety of disulfiram implants are subjects of ongoing research, and they should only be considered after thorough consultation with a qualified healthcare professional who can provide guidance based on current clinical evidence and individual patient circumstances.
For more detailed information on disulfiram, including its dosing, formulations, and considerations regarding implants, consulting the BNF and seeking advice from healthcare providers is recommended.

Acne, also known as acne vulgaris is a common skin disease and disorder characterized by muliple lesions in skin. It affects mostly face area but may also affect neck chest and back in severe cases.
Acne contains both inflammatory or noninflammatory lesions spread around that area.
Acne mostly affects ‘pilosebaceous units’ you which is the name for ‘hair follicles’.
Acne affects above mentioned area because these areas contain most of the oil glands.
Pathophysiology of acne scars
Acne scars are generally formed after inflammation due acne bacterial infections.
These infections occur in hair follicles by bacteria named Cutibacterium acnes.
The inflammation can be subsided using steroids or other anti-inflammatory medications.
But this is not our goal in this article. Rather we will deal regarding subsiding inflammation without use of modern medicine and chemical.
We will deal with acne and acne scars in a natural way.
Steps of getting rid of acne scars naturally
You can follow these steps to get rid of acne scars naturally.
Do not get acne:
Yes you didn’t expect this in first but this is what we should do if we never wabt scars.
Read below for details on acne prevention.
Treat acne on time.
Acne, also known as acne vulgaris, is a prevalent skin condition affecting millions worldwide. It is characterized by the appearance of multiple lesions on the skin, which may vary in size, type, and severity. While acne primarily affects the facial area, it can extend to other regions such as the neck, chest, and back, especially in severe cases. The condition can be distressing, not just because of its physical appearance but also due to the discomfort and potential for scarring it causes.
Types of Acne Lesions
Acne lesions can be broadly classified into two types: inflammatory and non-inflammatory. Non-inflammatory lesions include comedones, which are further divided into open (blackheads) and closed (whiteheads) comedones. Inflammatory lesions, on the other hand, encompass papules, pustules, nodules, and cysts, which often lead to redness, swelling, and discomfort in the affected areas.
Why Acne Occurs in Specific Areas
Acne predominantly affects regions rich in oil glands, such as the face, neck, chest, and back. These areas contain what is known as pilosebaceous units, a term used to describe hair follicles and their associated sebaceous (oil) glands. These glands produce sebum, an oily substance that helps lubricate and protect the skin. However, excessive sebum production, combined with dead skin cells and bacterial growth, can clog these follicles, leading to acne.
Understanding Acne Scars
Acne scars are a common aftermath of inflammatory acne. These scars form due to damage to the skin tissue caused by severe inflammation and infections within the hair follicles. The bacteria responsible for this inflammation is called Cutibacterium acnes (previously known as Propionibacterium acnes). When the body attempts to heal these inflamed areas, it produces collagen to repair the damage. If too much or too little collagen is produced, scars can form.
Managing Inflammation in Acne
One of the critical steps in preventing acne scars is managing inflammation effectively. Steroids and other anti-inflammatory medications are often prescribed to reduce redness and swelling. However, some individuals prefer to explore natural methods to address inflammation and prevent scarring.
Natural Ways to Address Acne and Acne Scars
While modern medicine offers numerous solutions, some people opt for natural approaches to manage acne and reduce the risk of scarring. Below are some steps and tips to tackle acne scars naturally:
Prevent Acne from Occurring Prevention is always better than cure. To avoid scars, it is essential to prevent acne in the first place. This involves adopting a skincare routine that includes cleansing, exfoliating, and moisturizing appropriately. Maintaining a healthy diet, managing stress, and staying hydrated can also help keep acne at bay. acne scar treatment
Timely Treatment of Acne If acne does occur, it is crucial to treat it promptly. Delaying treatment increases the risk of severe inflammation, which can lead to scarring. Natural remedies such as tea tree oil, aloe vera, and honey may help reduce mild acne.
Avoid Picking or Popping Pimples Picking or popping pimples can worsen inflammation and lead to permanent scarring. Allowing the skin to heal naturally or seeking professional help is always recommended.
Use Natural Anti-Inflammatory Remedies Natural ingredients such as turmeric (known for its anti-inflammatory properties), green tea, and chamomile can help reduce redness and swelling. These can be applied topically or consumed as part of a balanced diet.
Exfoliate Gently Gentle exfoliation with natural scrubs like oatmeal or sugar can help remove dead skin cells, promoting the growth of new, healthy skin. Over-exfoliation, however, should be avoided as it can irritate the skin.
Hydrate and Protect the Skin Keeping the skin well-hydrated is essential for its overall health. Using natural moisturizers like aloe vera gel or coconut oil can help maintain the skin’s moisture barrier. Additionally, wearing sunscreen protects the skin from harmful UV rays, which can worsen scars.
Apply Natural Scar Remedies Natural ingredients like rosehip oil, vitamin E, and shea butter are known for their scar-healing properties. Regular application can help fade scars over time.
By following these natural steps, you can manage acne and its scars effectively without relying on chemical treatments. Consistency and patience are key, as natural remedies often take time to show noticeable results.
