{"question": "Dennie Morgan folds are seen in", "exp": "Ans. b (Atopic dermatitis) (Ref. H - 18th/pg. 52, 52)Half of patients with Atopic dermatitis (AD) present within the first year of life, and 80% present by 5 years of age. About 80% ultimately coexpress allergic rhinitis or asthma. The infantile pattern is characterized by weeping inflammatory patches and crusted plaques on the face, neck, and extensor surfaces. The childhood and adolescent pattern is marked by dermatitis of flexural skin, particularly in the antecubital and popliteal fossae. AD may resolve spontaneously, but approximately 40% of all individuals affected as children will have dermatitis in adult life. The distribution of lesions may be similar to those seen in childhood; however, adults frequently have localized disease, manifesting as lichen simplex chronicus or hand eczema (see below). In patients with localized disease, AD may be suspected because of a typical personal history, family history, or the presence of cutaneous stigmata of AD such as perioral pallor, an extra fold of skin beneath the lower eyelid (Dennie-Morgan folds), increased palmar skin markings, and an increased incidence of cutaneous infections, particularly with Staphylococcus aureus. Regardless of other manifestations, pruritus is a prominent characteristic of AD in all age groups and is exacerbated by dry skin. Many of the cutaneous findings in affected patients, such as lichenification, are secondary to rubbing and scratching.SKIN FEATURES OF ATOPIC DERMATITIS# Atopic Pleat (Dennie-Morgan fold): An extra fold of skin that develops under the eye.# Cheilitis: Inflammation of the skin on and around the lips.# Hyperlinear Palms: Increased number of skin creases on the palms.# Hyperpigmented Eyelids: Eyelids that have become darker in color from inflammation or hay fever.# Ichthyosis: Dry, rectangular scales on the skin.# Keratosis Pilaris: Small, rough bumps, generally on the face, upper arms, and thighs.# Lichenification: Thick, leathery skin resulting from constant scratching and rubbing.# Papules: Small raised bumps that may open when scratched and become crusty and infected.# Urticaria: Hives (red, raised bumps) that may occur after exposure to an allergen, at the beginning of flares, or after exercise or a hot bath.# White dermographism: excessive redness along line of stroke with thin objecteTYPES OF ECZEMA (DERMATITIS)# Allergic contact eczema (dermatitis): A red, itchy, weepy reaction where the skin has come into contact with a substance that the immune system recognizes as foreign, such as poison ivy or certain preservatives in creams and lotions.# Atopic dermatitis: A chronic skin disease characterized by itchy, inflamed skin.# Contact eczema: A localized reaction that includes redness, itching, and burning where the skin has come into contact with an allergen (an allergy-causing substance) or with an irritant such as an acid, a cleaning agent, or other chemical.# Dyshidrotic eczema: Irritation of the skin on the palms of hands and soles of the feet characterized by clear, deep blisters that itch and bum.# Neurodermatitis: Scaly patches of the skin on the head, lower legs, wrists, or forearms caused by a localized itch (such as an insect bite) that become intensely irritated when scratched.# Nummular eczema: Coin-shaped patches of irritated skin--most common on the arms, back, buttocks, and lower legs--that may be crusted, scaling, and extremely itchy.# Seborrheic eczema: Yellowish, oily, scaly patches of skin on the scalp, face, and occasionally other parts of the body.# Stasis dermatitis: A skin irritation on the lower legs, generally related to circulatory problems.", "cop": 2, "opa": "Lichen planus", "opb": "Atopic dermatitis", "opc": "Keratosis pilaris", "opd": "Nummular eczema", "subject_name": "Skin", "topic_name": "Dermatitis Erythema", "id": "8e8e9959-22e7-4739-a4ee-22d96fc4a7a3", "choice_type": "single"}

{"question": "22 years women with diffuse hair loss for 1 month, with past history of enteric fever, before 4 months, likely cause", "exp": "Ans. is 'b' i.e. Telogen effluvium * Diffuse hair loss for 1 month with a history of enteric fever before 4 months suggest the diagnosis of Telogen effluvium.* To understand telogen effluvium, we need to have some knowledge of the hair growth cycle.Hair does not grow continuously on the human scalp.The anagen (growing) phase for terminal hair can extend 3 to 7 years and is a reflection of the size of the hair follicle.Catagen is the transitional portion of the hair growth cycle, between anagen and telogen and lasts only 1 to 2 weeks.During this time, there is a rapid involution and regression of the hair follicle. The hair follicle then enters the telogen phase, which is a relatively fixed period of time, approximately 100 days, regardless of the size of the hair follicle. There is no growth of the hair shaft during this phase. It is at the end of the telogen phase that the entire hair shaft, also often referred to as the club hair, will spontaneously shed, while a new hair shaft is forming within the hair canal. The white bulb at the end of the hair, along with the loosely attached collection of friable debris gives the shed hair its characteristic appearance. In the scalp of the healthy, young human adult, approximately 90% of the hair will be in the anagen (growth) phase and approximately 10% will be in the telogen (dormancy) phase.Less than 1% will be in the catagen (transitional) phase.What is Telogen Effluvium??When excessive amounts of hair simultaneously switch from anagen (growth) into telogen (dormancy) and subsequently shed several months later, the phenomenon is referred to as a telogen effluvium.Telogen effluviums can be acute or chronic.What causes Telogen Effluvium?In order to cause a large number of hair follicles to simultaneously switch from the anagen (growing) phase into the telogen (resting) phase, the body has to undergo some systemic insult.A telogen effluvium is not caused by topical medications. But because there is a required time lapse of several months between the inciting cause and the excessive shedding of hair, the exact cause of the telogen effluvium is often not positively identified.A typical and common case of telogen effluvium would be the episode of severe shedding of hair that may occur approximately 100 days after a woman has given birth. The inciting factor is probably the abrupt hormonal changes that occur at the end of pregnancy. All of the hair grows back within a year.Other causes of telogen effluvium include illness,major physicaltrauma,menopause,crash diets,severe psychological stress,major surgery (especially with general anesthesia),hypo- or hyperthyroidism,anemia's,acute and severe blood loss,heavy metal poisoning, etc.Chronic illness such as malignancy, and any chronic debilitating illness,such as systemic lupus erythematosus,end-stage renal disease, - or liver disease can cause telogen effluvium.InfectionsTyphoid, malaria, dengue Anagen effluviumAnagen effluvium is the loss of anagen hair which typically happens after radiation therapy of chemotherapy especially with alkylating agents.", "cop": 2, "opa": "Androgenic alopecia", "opb": "Telogen effuvium", "opc": "Anagen effuvium", "opd": "Alopecia areata", "subject_name": "Skin", "topic_name": "Anatomy of Skin", "id": "d9beac3a-28f7-427c-b04a-7c0aed9ed11f", "choice_type": "single"}

{"question": "Presumably, the Varicella zoster virus infects", "exp": "(A) Dorsal root ganglion[?]Varicella-Zoster Virus (VZV):Herpes Zoster Herpes zoster (shingles) is a sporadic disease that results from reactivation of latent VZV from dorsal root ganglia.Most patients with shingles have no history of recent exposure to other individuals with VZV infection.Herpes zoster is characterized by a unilateral vesicular dermatomal eruption, often associated with severe pain. The dermatomes from T3 to L3 are most frequently involved.If the ophthalmic branch of the trigeminal nerve is involved, zoster ophthalmicus results.The onset of disease is heralded by pain within the dermatome, which may precede lesions by 48-72 h; an erythematous maculopapular rash evolves rapidly into vesicular lesions.In a few patients, characteristic localization of pain to a dermatome with serologic evidence of herpes zoster has been reported in the absence of skin lesions, an entity known as zoster sine herpetica.In Ramsay Hunt syndrome, pain and vesicles appear in the external auditory canal and patients lose their sense of taste in the anterior two-thirds of the tongue while developing ipsilateral facial palsy.The geniculate ganglion of the sensory branch of the facial nerve is involved.CNS involvement may follow localized herpes zoster. Many patients without signs of meningeal irritation have CSF pleocytosis and moderately elevated levels of CSF protein. Symptomatic meningoencephalitis is characterized by headache, fever, photophobia, meningitis and vomiting.Human alpha-herpesvirus Causes varicella (chickenpox) and herpes zoster (shingles) Primary VZV infection leads to chicken pox VZV establishes latency in dorsal root ganglia after primary infection VZV can reactivate at a later time, causing herpes zoster.

It is effectively made non-infectious by treatment with rifampicin for 3 weeks ( KERALA 2007)and by dapsone for 90 days. Local application of rifampicin (drops or spray) may destroy all the bacilli within 8 days.Anti-leprotic drugsRIFAMPICINIt is bactericidal to M.leprae and rapidly renders leprosy patients noncontagious. Up to 99.99% M.leprae are killed in 3-7 days.MOA-Rifampicin binds to the beta subunit of bacterial DNA-dependent RNA polymerase and thereby inhibits RNA synthesisOther indications include tuberculosis, prophylaxis of meningococcal and H.influenza meningitis and carrier state,combined with doxycycline in brucellosis, 2nU/3rd choice drug in MRSA,diphtheroids and legionella.Adverse effectsImparts a harmless orange color to urine, sweat, tears, and contact lenses .Rashes, thrombocytopenia, and nephritis.Cholestatic jaundice and occasionally hepatitis.Rifampin commonly causes light-chain proteinuria.If administered less often than twice weekly, rifampicin causes a flu-like syndrome characterized by fever, chills, myalgias, anemia, and thrombocytopenia and sometimes is associated with acute tubular necrosis. Rifampin strongly induces most cytochrome P-450 isoforms.DAPSONE (DDS)-Dapsone (diaminodiphenylsulfone).Like the sulfonamides, inhibits folate synthesis.

{"question": "TOC for penicillin resistant gonorrhoea", "exp": "B i.e. Ceftriaxone Neisseria gonorrhea is a gram negative, aerobic, non-motile, non-sporeforming, diplo/mono-cocciQ, exclusively a human pathogen that principally infects host columnar epithelium. It is oxidase positive like other Neisseria species, from which it is distinguished by their ability to grow on selective media & to utilize glucose but not maltose, sucrose or lactose. Gonorrhoea is, the second most common (after Chlamydia trachomatis which is the most common) genital /sexually transmitted infection in US, UK and other developed countriesQ (Harrison 1442; Rook's 34.24). The incidence of gonorrhea is higher in developing countriesQ than industrialized nations predominantly affecting young, nonwhite, unmarried, less educated urban population. (Harrison 1220) Chlamydia trachomatis is the most common cause of non gonococcal urethritis (NGU) and postgonococcal urethritis (PGU)Q. PGU refers to NGU developing in men 2-3 weeks after treatment of gonococcal urethritis with single doses of agents such as penicillin or cephalosporins which lack activity against Chlamydia. In US most of acute urethritis cases are NGU and C. trachomatis is implicated in most (30-50%) of these casesQ. The other causes of NGU are Ureaplasma urealyticum, Mycoplasma genitalium, Trichomonas vaginalis and herpes simplex virus (HSV). Gonorrhoea is a STD which commonly manifests as cervicitis (primary site of infection in females), urethritis (most common/primary site of infection in males presenting as rapid onset severe burning dysuria with profuse purulent discharge)Q, proctitis & conjunctivitis. If untreated it can 1/t local complications such as endometritis, salpingitis, tuboovarian abscessQ, baholinitis, peritonitis and perihepatitis (Fitz-Hugh Cuis Syndrome) in females; peri urethritis and epididymitisQ in male patients and ophthalmia neonatorum in new borns. Disseminated gonococcemia is uncommon & 1/t skin lesions, tenosynovitis, ahritis and in rare cases endocarditis & meningitis. Because of ascending spread of infection testis is spared or (uncommonly) last to be involvedQ only after urethritis, prostatitis, epididymitis in gonorrhea. Single dose regimens of 3rd generation cephalosporins ceftriaxone (IM) and cefixime (oral) are the mainstays of therapyQ for uncomplicated gonococcal infection of urethra, cervix, rectum, or pharynx. Septinomycin is an alternative (2nd) regimen for uncomplicated gonococcal infections in penicillin allergic patients. All 3 drugs are suitable for pregnant & breast feeding women. The new management for complaints of urethral discharge involves a combined modality of treatment for N. gonorrhea and C. trachomatisQ as most cases are d/t coinfection with both pathogens and incorporate an agent eg. azithromycin or doxycycline that is effective agenist chlamydial infection. Pregnant women who should not take doxycycline, should receive concurrent treatment with a macrolide antibiotic for possible chlamydial infection.
