| REVIEW OF LITERATURE: RINGWORM (TINEA)
DEFINITION Ø Dermatophytes are fungi capable of causing superficial skin infections known as Ringworm or dermatophytosis. (6) Ø It is a chronic infection of the hair, skin or nails by dermatophytes (a type of fungi that invade the superficial layer of epidermis and survive on the keratin of the skin, hair and nails) (7) Ø There are three genera of dermatophytes: Trichophyton, Microsporum and Epidermophyton. They are grouped according to their natural habitat as geophilic (soil), zoophilic (animals), and anthropophilic(humans). (8) Ø Transmission may be indirect (via desquamated epithelium) or direct through bodily contact. (8) HISTORICAL VIEW à Robert Remak (1815-1865): discoverer of the fungal character of Dermatophytoses Robert Remak was the first scientist to undertake successful research on fungal skin infections. A neurologist, physiologist, and embryologist, Remak was the first to observe the fungal changes causing the disease of favus; however, he gave credit for the discovery to Professor Johann Schönlein and denied all attempts by others to credit him with the discovery by calling them a mistake. He named the disease Achorion schönleinii; however, over time, the name was changed to Trichophyton schoenleinii. (9) Ø PREDISPOSING FACTORS Warm, humid climate, poor nutrition and hygiene, obesity, diabetes mellitus and debilitating illness. (8) CAUSES Ø Age, sex, genetic and racial factors Ø Endocrine and metabolic factors Ø Temperature and microenvironment Ø Competing organisms and co-pathogens (10) PATHOLOGY Ø Invasion of the epidermis by dermatophytes follows a common pattern, starting with adherence between arthroconidia and keratinocytes, followed by penetration through and between cells and the development of a host response. (10) CLINICAL FEATURES These depend upon the site and the species of fungus involved, v Tinea corporis - Typical infections consist of erythematous, scaly plaques, with an annular appearance that accounts for the common name “ringworm.†(7) The lesion starts as a papule which spreads ring-like peripherally with central clearing. The lesions are usually circinate with an active border consisting of vesicles and scaling. (8) v Tinea cruris - Deep inflammatory nodules or granulomas occur in some infections, most often those inappropriately treated with mid- to high-potency topical glucocorticoids. Involvement of the groin. It presents as a scaling, erythematous eruption sparing the scrotum v Tinea pedis - variable erythema, edema, scaling, pruritus, and occasionally vesiculation. Infection of web space between the fourth and fifth toes. v Tinea unguium - opacified, thickened nails and subungual debris. v Tinea capitis - non-inflammatory infection with mild scale and hair loss that is diffuse or localized. Inflammatory dermatosis with edema and nodules. (7) v Tinea Barbae - It is invasion of hairs of beard by fungus, resulting in inflammatory lesion with follicular pustules. Usually due to unhygienic shaving by road side barbers. (11) Ø CLINICAL CLASSIFICATION
| Tinea corporis or Tinea circinata | ringworm infection of body | | Tinea pedis or athlete’s foot | ringworm infection of the foot | | Tinea cruris or Eczema-marginatum | ringworm infection of the groin and buttock | | Tinea unguium or onychomycosis | ringworm infection of the nails | | Tinea capitis or Tinea tonsurans | ringworm infection of the head, scalp, eyebrows, eyelashes | | Tinea favosa | ringworm infection of the scalp | | Tinea manuum | ringworm infection of the hand | | Tinea barbae | ringworm infection of the beard | | Tinea incognito or Steroid-modified tinea | ringworm infection of skin {odd tinea appearance} occurs following the application of steroidal cream | (8) (10) DIAGNOSIS Dermatophytes are seen as hyphae and spores in skin scales (obtained by scraping with a scalpel) or in nail or hair samples, and mounted in 10% KOH for 20 minutes. These can also be cultured on Sabouraud’s medium, or on Dermatophyte Test Medium (DTM). (8) Nail clippings may be sent for histologic examination with periodic acid–Schiff (PAS) stain. (7) DIFFERENTIAL DIAGNOSIS · Tinea capitis - Alopecia areata, Seborrheic dermatitis, Psoriasis, Bacterial infections and tumors, trichotillomania · Tinea corporis - Nummular dermatitis, Atopic dermatitis, Tinea versicolor, Granuloma annulare, Candidiasis, psoriasis, pityriasis rosea · Tinea manuum - Irritant or allergic contact dermatitis, Psoriasis · Tinea cruris – Candidiasis, Seborrheic dermatitis, Psoriasis and lichen simplex chronicus. · Tinea pedis - Contact dermatitis, Dyshidrotic eczema (pompholyx), Psoriasis · Tinea unguium – Psoriasis, paronychia, trauma. (12) COMPLICATIONS à These include permanent alopecia due to scarring and an allergic vesicular reaction on the sides of fingers and palms. Atypical presentations of tinea occur in the immunosuppressed and when the rash is mistreated with topical steroids (“tinea incognitoâ€). (13) Ø MANAGEMENT Ø Prophylaxis 1. Patients who sweat a lot should change their clothes frequently, wear cotton socks and avoid synthetic material. 2. Clothes, especially the underwear, and towels should be boiled in hot water. 3. Footwear should be of the open type permitting sufficient aeration. 4. Intertriginous areas should be kept dry with powders, e.g. talcum or antifungal powder. 5. Shampoo the hair immediately after visit to the barber’s shop. (8) Ø Treatment Ø Treatment can be topical (terbinafine or miconazole cream) or systemic (terbinafine, griseofulvin or itraconazole). (6) Ø Homoeopathic management “If we do not increase our knowledge of the capabilities of our homoeopathic drugs, our homoeopathic art will become static. It will make no progress.†(14) -Dr. H.A. Robert As we all know, our homoeopathic materia medica has been enriched with innumerable and valuable drugs. We are using practically the same materia medica that we did fifty or more years ago. It requires no alteration but we need a deeper acquaintance with our remedies by applying it therapeutically. (14) Homoeopathy has been defined as the Science of Therapeutics which means that department of medical science which relates to the treatment of disease and action of remedial agents on the human organism, both in health and disease. So, some of homeopathic remedy which are much important for treatment of ringworm from sourcebook like pocket manual of homoeopathic materia medica & repertory by W. Boericke, Materia Medica of Homoeopathic Medicines by Dr. S.R. Phatak are as under; v Arsenicum album: Itching, burning, swellings; oedema, eruption, papular, dry, rough, scaly; worse cold and scratching. Malignant pustules. Ulcers with offensive discharge.

(18) Ø According to Dr. Richard Hughes… Tinea is a generic name, applicable to all parasitic affections, whether they be of animal or of vegetable origin. The " tinea tonsurans " is the ringworm of the scalp, "Tinea favosa " is now commonly called " favus." The treatment of this disease is one of the triumphs of homoeopathy, re commending Sulphur, Dulcamara, Viola tricolor, Oleander, and Hepar sulphuris according to the symptoms. " Tinea circinata,’: or ringworm of the surface (which must not be confounded with herpes circinatus, which is a constitutional affection), must be similarly treated (without epilation), as also " tinea decalvans "—the parasitic form of alopecia areata, and " tinea " or " pityriasis versicolor " (chloasma). Sulphurous acid makes an excellent lotion for these affections. Herpes circinatus (which must not be confounded with tinea circinata—" ringworm of the surface") has in my hands, since the proving of Tellurium produced so similar an eruption, always been treated by this remedy. Ringworm—That this disease is, when recent, amenable to internal remedies alone, seems to disprove the theory of its primarily parasitic origin; The great medicine for it is Sepia, at about the 6th dilution. But if this fails, you must resort to some local parasiticides, of which a solution of Sulphurous acid or of corrosive sublimate is the best. (19) Ø According to J. C. Burnett (M.D.) … “The trichophyton is not the disease itself, but its organic scavenger. Cure the internal disease, and this scavenger dies.†(20) -Dr. J. Compton Burnett à Ringworm is an Internal Disease of the organism having for its outward sign the ringworm consisting of fungi thriving in a certain order: the fungi are the guests of the diseased host; cure the host’s diseased state, and the fungus—the ringworm—dies off from lack of a proper medium. à The internal treatment of ringworm by Sulphur, Sepia, and Tellurium is good, the treatment of ringworm by the internal administration of very infrequent doses of high potencies of Bacillinum is direct, exact, radical, and beyond compare; the remedy being pathologically homoeopathic to the whole morbid state and crasis of the individual, and not merely pathologically similar to the superficial cutaneous manifestations. à In daily life we find ringworm a difficult disorder to cure: a few cases yield to almost any sensible treatment, but the bulk of them offer a stubborn resistance. 1) it is a constitutional complaint. 2) it is generated by the together-being of numbers of young people in close spaces i.e., by their personal emanations, or anthropotoxine. 3) it is so to speak, "subtuberculosis." 4) it is curable by its pathologic similimum here termed Bacillinum, in high potency, internally and infrequently administered. 5) That the mycosis is merely the concomitant external manifestation of the disease and not the disease itself. 6) the external treatment of the disease is irrational, unscientific, and, probably, harmful to the patient. 7) it is commonly bred in schools. 8) truly healthy children cannot catch it because the fungus cannot grow upon such. 9) There is, therefore, no reason why a ringworm child should be excluded from school life or the company of its fellows in home life. 10) And, finally, that the trichophyton of ringworm is to ringworm what the bacillus of Koch is to tuberculosis, —the trichophyton and the bacillus being, moreover, nearly related to one another.
