A common mode of transmission is through the water in swimming pools; thus the disease may occur in local epidemics (swimming pool conjunctivitis). It is also transmitted from the mother to the newborn.Treatment- azithromycin or doxycycline | Ophthalmology | Inflammations of Conjunctiva - Infective |

The patient is allowed to communicate unguided, by using 'free association'. The therapist remains passive with a non-directive approach; however, the therapist constantly challenges the existing defences and interprets resistance (during the therapy) and transference (patient's feelings, behaviours and relationship with the therapist). No direct advice is ever given to the patient. The crux of the therapy is on interpretation. During the therapy, the patient typically lies on the couch, with the therapist sitting just out of vision.

Meherban Singh 5/e, p 227
“Steroid treatment is contraindicated in presence of overt infection.”
Fernando Arias 3/e, p 220
Steroid therapy in preterm labour:
Steroids are recommended for all women in preterm labour before 32 weeks with or without membrane ruptures in whom there is no evidence of chorioamnionitis. According to ACOG, single dose steroid injection is recommended between 24 to 32 weeks. There is no concensus regarding treatment between 32-34 weeks. Corticosteroid therapy is not recommended before 24 weeks.
Advantage:
Steroids reduce the rate of respiratory distress syndrome, intraventricular hemorrhage and necrotising enterocolitis in the newborn.
The effect of treatment is maximal between 24 hours of the first dose and uptil 7 days.
Earlier it was recommended to give repeated doses weekly till the patient delivers but this practice is associated with significant fetal and neonatal side effects like cerebral palsy and should be abandoned.
Betamethasone is the steroid of choice as it also prevents periventricular leukomalacia although dexamethasone can also be used.
Dose:
Betamethasone = 2 doses of 12 mg, 24 hours apart,
Dexamethosane: 4 doses of 6 mg, 12 hours apart. | Gynaecology & Obstetrics | null |

| multi | After wounding, there is transient vasoconstriction mediated by catecholamines, thromboxane, and prostaglandin F2 (PGF2a). This period of vasoconstriction lasts for only five to ten minutes. Once a clot has been formed and active bleeding has stopped, vasodilatation occurs in an around the wound. Vasodilatation increases local blood flow to the wounded area, supplying the cells and substrate necessary for fuher wound repair. The vascular endothelial cells also deform, increasing vascular permeability. The vasodilatation and increased endothelial permeability is mediated by histamine, PGE2, and prostacyclin as well as growth factor VEGF (vascular endothelial cell growth factor). These vasodilatory substances are released by injured endothelial cells and mast cells and enhance the egress of cells and substrate into the wound and tissue. | Surgery | null |

| single | The uptake of exogenous cholesterol by cells results in a marked suppression of endogenous cholesterol synthesis. Low-density human lipoprotein not only contains the greatest ratio of bound cholesterol to protein but also has the greatest potency in suppressing endogenous cholesterogenesis. normally suppress cholesterol synthesis by binding to a specific membrane receptor that mediates inhibition of hydroxymethylglutaryl (HMG) coenzyme A reductase. In familial hypercholesterolemia the LDL receptor is dysfunctional, with the result that cholesterol synthesis is less responsive to plasma cholesterol levels. Suppression of HMG CoA reductase is attained using inhibitors (statins) that mimic the structure of mevalonic acid, the natural feedback inhibitor of the enzyme. Note: The LDL (apoB-100, E) receptor is defective in familial hypercholesterolemia, a genetic condition in which blood LDL cholesterol levels are increased, causing premature atherosclerosis.

– Refractory contact ulcer
– Peptic laryngeal granuloma
– Acid laryngitis (Heart burn, burning pharyngeal discomfort, nocturnal chocking due to interarytenoid pachydermia)

| multi | A proto-oncogene is a normal gene that could become an oncogene due to mutations or increased expression. Proto-oncogenes code for proteins that help to regulate cell growth and differentiation. Proto-oncogenes are often involved in signal transduction and execution of mitogenic signals, usually through their protein products. Upon acquiring an activating mutation, a proto-oncogene becomes a tumor-inducing agent, an oncogene. Examples of proto-oncogenes include RAS, WNT, MYC, ERK, and TRK. The MYC gene is implicated in Burkitt's Lymphoma, which stas when a chromosomal translocation moves an enhancer sequence within the vicinity of the MYC gene. The MYC gene codes for widely used transcription factors. When the enhancer sequence is wrongly placed, these transcription factors are produced at much higher rates. Another example of an oncogene is the Bcr-Abl gene found on the Philadelphia Chromosome, a piece of genetic material seen in Chronic Myelogenous Leukemia caused by the translocation of pieces from chromosomes 9 and 22. Bcr-Abl codes for a tyrosine kinase, which is constitutively active, leading to uncontrolled cell proliferation. | Pathology | General pathology |

They also occur in epidermal invaginations of the plantar foot surface called rete ridges. Most often, they are associated with sensory nerve endings, when they are known as Merkel nerve endings (Merkel cell-neurite complex). They are associated with slowly adapting (SA1) somatosensory nerve fibers. They are associated with the sense of light touch discrimination of shapes and textures. They can turn malignant and form the skin tumor known as Merkel cell carcinoma.DERIVATIVES OF NEURAL CRESTDerivative of neural crestDeveloping partsNeurons1.

| single | Ans. (d) Testicular torsion.Testicular torsion is most common between 10 and 25 years of age, although a few cases occur in infancy. Typically, there is sudden agonising pain in the groin and the lower abdomen. The patient feels nauseated and may vomit. Torsion of a fully descended testis is usually easily recognized. The testis seems high and the tender twisted cord can be palpated above it. The cremasteric reflex is lost.Image source- style="font-family: Times New Roman, Times, serif"> | Surgery | Miscellaneous (Testis & Scrotum) |
