Pathogenesis of dry eye in leprosy and tear functions.

Seventy-five leprosy patients and an equal number of age- and sex-matched controls were examined for tear functions, using Schirmer's test and tear break up time (BUT). There was no statistically significant difference in the Schirmer's test, but the tear BUT showed a statistically significant lower value of < 10 seconds in multibacillary patients compared to paucibacillary patients. Leprosy patients with lagophthalmos and decreased corneal sensation showed a lower value of tear BUT which was also statistically significant.

Nocardia farcinica pleuritis in a lepromatous patient with severe necrotizing reaction: an unusual presentation.

A young, male, lepromatous leprosy patient with a severe necrotizing erythema nodosum leprosum reaction treated with prolonged oral steroids and thalidomide developed pleuritis that was caused by a rare opportunistic pathogen, Nocardia farcinica. This organism was resistant to most antibiotics but was susceptible to amikacin and minocycline. During the course of treatment the patient developed severe gastritis which necessitated the removal of clofazimine and the inclusion of an H2 receptor antagonist.

Histological changes in the nerve, skin and nasal mucosa of patients with primary neuritic leprosy.

Primary neuritic leprosy (PNL) presents as a peripheral neuropathy with no visible skin patches and skin smears negative for acid fast bacilli. The pathogenesis of PNL is poorly understood. The aim of the study was to document the histological changes in the nerve, apparently normal skin and nasal mucosa in PNL and to study its significance to the pathogenesis of leprosy lesions.

Long-term follow up of multibacillary leprosy patients with high BI treated with WHO/MDT regimen for a fixed duration of two years.

Forty-six, newly detected, previously untreated multibacillary (MB) patients with a bacterial index (BI) of > or = 3+ who had received WHO/MDT for 2 years were followed up for a total duration of 424 person-years and a mean duration of 9.26 +/- 2.98 years per patient.

Relapse as histoid leprosy after receiving multidrug therapy (MDT); a report of three cases.

The histoid type of leprosy has been described as occurring in lepromatous leprosy patients who relapse after many years of apparently successful dapsone monotherapy. Three patients who had received the World Health Organization-recommended regimens of multidrug therapy (WHO/MDT) relapsed as histoid leprosy 12-15 years after completion of treatment. In one patient, through mouse foot pad studies, the bacilli were found to be sensitive to rifampin and clofazimine and resistant to dapsone.

Bacteriological study of pus isolates from neuropathic plantar ulcers associated with acute inflammatory phase.

In this retrospective study, sensitivity of organisms cultured from ulcers of leprosy patients without and with diabetes mellitus, diabetic patients without leprosy and patients with ulcers from other causes was examined. The profile of organisms grown from these groups of patients did not differ significantly. However, there was a high prevalence of organisms like Proteus, E.

Monitoring motor nerve function in leprosy patients.

Manual muscle strength testing has an important function in the management of leprosy patients. Its importance was first recognized in the 1960s, especially when following patients who were started on steroid treatment to monitor the nerve function and the effect of treatment. In those days, and still in many centres today, many or all muscles were tested that are innervated by the nerves that can be at risk in leprosy.

Leprosy affected beggars as a hidden source for transmission of leprosy.

Background & Objectives: Despite the large scale implementation of multidrug therapy (MDT), the incidence rates of leprosy have not declined in several hyperendemic countries. Before searching for non-human reservoirs of leprosy it would be necessary to look for hidden human sources. This would include destitute leprosy affected persons who resort to begging and operate in congested areas.

Epithelioid granuloma in the iris of a lepromatous leprosy patient; an unusual finding.

This case report depicts a case of histopathologically confirmed polar lepromatous (LL) leprosy with a bacterial index of 4+. He experienced recurrent episodes of erythema nodosum leprosum (ENL) in the first 5 years after diagnosis. Skin smears became negative after 6 years of dapsone monotherapy and have remained negative since that time.

Study of the problem of hidden cases of leprosy among "inaccessible" section of urban population in Madras City.

A questionnaire survey was conducted amongst 1300 general practitioners (GPs) of Madras city to assess the magnitude of leprosy problem amongst the upper middle class and upper class populations who are getting treatment from these GPs. A total of 2944 leprosy patients were being treated by 200 GPs. One third of these patients belonged to the upper middle/upper class section of the population living in the city of Madras.

Papillon-lefevre Syndrome : Improvement of Skin Lesions After the Loss of Permanent Teeth.

A case of Papillon-Lefevre syndrome (PLS) showed improvement of skin lesions after the loss of permanent teeth which is an unusual feature. The case is being reported because of this feature.

Pathology of a lepromatous eye.

Histopathological examination of an enucleated eye from a lepromatous leprosy patient showed the cornea, ciliary body, and part of the choroid to be infiltrated by macrophages filled with Mycobacterium leprae. The walls of blood vessels in the sclera, ciliary body and the anterior choroid demonstrated the presence of M. leprae, giving credence to the blood-borne entry of M.

Histopathological activity in paucibacillary leprosy patients after ROM therapy.

Histopathological activity was assessed in the skin tissue of 13 skin-smear negative, borderline tuberculoid leprosy patients after administration of a single dose of ROM (rifampin 600 mg, ofloxacin 400 mg and minocycline 100 mg) therapy. Biopsies taken just before therapy showed Mycobacterium leprae to be present in eight cases. After 6 months, only three showed granulomatous lesions and others showed only resolving or inactive lesions.

Hypopigmented face patches; their distribution and relevance to ocular complications in leprosy.

Eighty-two leprosy patients with hypopigmented patches over the face (cases) and an equal number of age-, sex-, and classification-matched leprosy patients without any hypopigmented patches over the face (controls) were examined for the distribution of hypopigmented facial patches, areas of anesthesia over the face, and eye complications. The hypopigmented patches did not follow any pattern and overlapped in the areas of sensation supplied by the three branches of the trigeminal nerve. Anesthesia over the face, evaluated by a Semmes-Weinstein monofilament which exerted a force of 0.

Being a female leprosy patient in south India.

The problems of women patients as revealed by a case study of a woman patient and a questionnaire study of 100 leprosy patients (47 men and 53 women) are presented. These include, besides general ones like ignorance of facts about the disease, specific ones like lack of privacy during clinical examination, indifference towards women's feelings and difficulties in communicating with male workers. A greater sensibility towards the sentiments and problems of women patients, on the part of the health service is required to amend the situation.

Lepromatous lymphadenopathy and concomitant tuberculous axillary lymphadenitis with sinus. A case report.

A 25-year-old male patient with florid lepromatous leprosy presented with right axillary lymphadenopathy and a discharging sinus. He also had scabies with chronic right otitis media. Histopathological examination of the lymph node revealed lepromatous lymphadenitis coexisting with tuberculosis.

Nasal mucosa and skin of smear-positive leprosy patients after 24 months of fixed duration MDT: histopathological and microbiological study.

The skin and nasal mucosa of 10 lepromatous leprosy patients who had completed 24 doses of fixed duration multidrug therapy (MDT) but who continued to be skin-smear positive for acid-fast bacilli (AFB) were examined histopathologically. The nasal mucosa showed granuloma fractions that exceeded those seen in the skin specimens, signifying that activity in this region subsides much more gradually than the activity in the skin. Mouse foot pad studies done using T900r mice with an inoculum from the nasal mucosa biopsy specimens of these patients did not demonstrate any growth of Mycobacterium leprae, indicating that these bacilli were not viable.

Impact of leprosy on the quality of life.

Leprosy is considered by many as not merely a medical condition, but as a condition encompassing psychological, socioeconomic and spiritual dimensions that dehabilitate an individual progressively, unless properly cared for. The present study was undertaken to document the nature and extent of decreases in the quality of life (QOL) of an affected person. The World Health Organization questionnaire on quality of life was given to a representative random sample of 50 leprosy-affected persons and 50 unaffected individuals in the Bommasamudram Taluk of Chittoor District, Andhra Pradesh, India.

Childhood leprosy in an endemic area.

A study was done on 794 new cases of leprosy among children (aged 0-14 years) detected and treated with MDT during 1990-1995 in Gudiyatham Taluk, South India. Incidence rates of leprosy and proportion of multibacillary cases increased with age, while bacillary + tuberculoid was most common. Over 80% had a single patch and most children were detected through surveys.

Infectious keratitis in leprosy.

Aim: To describe leprosy characteristics, ocular features, and type of organisms that produce infective corneal ulcers in leprosy patients.

Method: The records of all leprosy patients admitted for treatment of corneal ulcers between 1992 and 1997 were reviewed.

Results: 63 leprosy patients, 53 males and 10 females, are described.

Incidence of nerve damage in leprosy patients treated with MDT.

The incidence rates of sensory and motor impairments during and after multidrug therapy (MDT) are reported for a prospective cohort of patients who had no nerve damage at registration (N = 1621). Sensory and motor loss increased with age and both were high among multibacillary patients as compared with paucibacillary patients. The lateral popliteal (common peroneal) and posterior tibial nerves seem to be most affected for sensory loss; whereas the posterior tibial and ulnar nerves are mainly responsible for motor loss.

Quantitative assessment of facial sensation in leprosy.

The trigeminal and great auricular nerves which supply sensation to the face are affected in leprosy. No objective sensory testing methods have been devised for testing sensation in the face. Testing for corneal sensation to ascertain trigeminal nerve or visualization and palpation of the great auricular nerve alone may not be enough to establish the involvement of these nerves.

Histological studies in primary neuritic leprosy: changes in the nasal mucosa.

The nasal mucosae of 39 cases of primary neuritic leprosy (PNL) registered at Karigiri were studied histologically to determine nasal mucosal involvement in PNL and its relevance to the pathogenesis of the disease. Specific changes of leprosy were seen in 20 (51%) biopsies, ranging from macrophage granulomas with acid fast bacilli, to epithelioid granulomas and nerve inflammation. The remaining biopsies revealed chronic inflammatory changes of the mucosa or mild non-specific nerve changes.

Histological studies in primary neuritic leprosy: changes in the apparently normal skin.

The visually normal skin of 196 patients diagnosed clinically to have primary neuritic leprosy was studied histologically to determine whether there were any specific changes due to the disease in this site. Histological changes due to leprosy were seen in 32.1% of the patients, and included, indeterminate leprosy in 19.
