  Supraventricular tachycardia (SVT) is a rhythm disturbance originating at or above the atrioventricular (AV) node, characterized by a narrow complex (QRS < 120 milliseconds) with a rate exceeding 100 beats per minute (bpm). The common types of SVT encompass atrioventricular nodal re-entrant tachycardia, atrioventricular re-entrant tachycardia, and atrial tachycardia. The differential diagnosis comprises sinus tachycardia, atrial tachycardia, junctional tachycardia, atrial fibrillation, atrial flutter, or multi-atrial tachycardia. Factors such as medications, caffeine, alcohol, physical or emotional stress, or cigarette smoking can trigger SVT in susceptible individuals. Electrical conduction in the heart commences at the sinoatrial (SA) node, proceeding to the atrial tissue and the AV node. At the AV node, there's an approximately 100-millisecond delay in the electrical signal. Subsequently, the signal navigates through the His-Purkinje system, branching into the left and ri...

  Hidradenitis suppurativa (HS), also known as acne inversus, is a chronic inflammatory skin disorder characterized by lesions such as deep-seated nodules, abscesses, draining tracts, and fibrotic scars. These lesions typically develop in areas where skin rubs together or where there are many sweat glands, with common sites including the axillary, groin, perianal, perineal, and inframammary regions. Depending on the stage of the disease, individuals may experience painful, tender papules, cysts, or nodules, along with areas of scar tissue. The condition may also involve the discharge of foul-smelling pus from the skin and the formation of sinus tracts under the skin. While there is no cure for HS, various treatment options are available based on the severity of the condition. For mild to moderate cases, treatment may involve the use of antibiotic creams, lotions, or washes, oral antibiotics, local steroid injections, minor surgical procedures, laser therapy, and hormone-regulatin...

  Essential tremor (ET) is among the most prevalent and common neurodegenerative movement disorders. It is an enhanced physiological monosymptomatic condition transmitted as an autosomal dominant trait. Essential tremor (ET) could be childhood- and adult-onset cases, which are similar and usually appear in the second decade but can begin as early as 2 years of age. Typically, the tremor is marked in the upper limbs and involves the head, voice, lower limbs, and trunk. Despite its high prevalence, ET is still frequently undiagnosed or misdiagnosed, and public recognition of the disease and its impact remain low. Furthermore, many patients with ET, particularly those with initial episodes of tremors, do not seek medical care, remain undiagnosed, and do not receive treatment. Essential tremors most often affect the hands and arms bilaterally and are symmetric; also, cases of asymmetric essential tremors have been reported. In most cases, the tremor frequency of e...
