Parameters affecting the decay of some organophosphorus pesticides: a study by high-performance liquid chromatography.
An HPLC procedure has been developed to follow the decay of malathion and methylparathion under control conditions using an mu-Bondapak C18 column with a mixture of acetonitrile and water to mobile phase and an ultraviolet detector for detection. Studies have been conducted to monitor their degradation in water and soil at different temperatures, pH and organic content. The results show that the persistence of the pesticides decreases with increase in temperature, pH and organic content.

Separation of endosulphan and its major metabolites by GC and HPLC.
Efficient gas-liquid chromatography and high-performance liquid chromatography methods for the separation of endosulphan I and II and its major metabolites have been developed using a glass column packed with 3% OV-225 and a C18 reversed-phase column with acetonitrile:water (70:30 v/v) as mobile phase, respectively.

Identification of metabolites of malathion in plant, water and soil by GC-MS.
Metabolism of malathion (O,O,-dimethyl S-[1,2-bis(ethoxy carbonyl)-ethyl]phosphorodithioate) has been studied in plants, water and soil. A number of products identified by gas chromatography-mass spectrometry (GC-MS), have been formed by de-esterification, oxidation and hydrolysis of malathion. Hydrolysis of the P-S and C-S bonds occur in alkaline pH 8.0 and acidic pH 5.5, respectively.

Rapid diagnosis of typhoid fever.
A Reverse Passive Haemagglutination Test (RPHA) was designed for the detection of Salmonella typhi antigen and rapid diagnosis of typhoid fever. Two per cent fresh sheep RBC's were coated with 32 micrograms/ml of immunoglobulin. The minimal detectable level of the antigen was 1250 micrograms/ml. Cross reactions were observed with the samples of patients suffering from Salmonella paratyphi A and pseudomonas infections. The RPHA established was used for the detection of S. typhi antigen in culture broths from 100 patients with clinically suspected typhoid fever with culture and/or widal positive, 50 patients with septicemia caused by bacteria other than S. typhi and 50 normal, afebrile healthy controls. It was found that the sensitivity and specificity of this assay was 70% and 92% respectively.

Palmoplantar lesions in leprosy.
Palms and soles are considered immune to leprosy. A study was carried out to assess the frequency of lesions over palms and soles and to correlate their occurrence with various parameters. Two hundred eighty leprosy patients were screened for lesions over palms and soles. Palmo-plantar lesions were observed in 10% of the patients screened. Slit-skin smears and biopsies were done from routine sites and palmo-plantar lesions. Histopathology and slit-skin smear confirmed the presence of disease. Eight were in type I reaction, and 50% of patients with type I reaction screened showed lesions over palms and/or soles. The reason for this is not known; probably inapparent lesions become apparent during reactions. Lesions of various morphology were observed. Silky hand was observed in one case.

Leprosy and herpes zoster; an association or dissociation?
Nerve involvement is common to the pathogenesis of both leprosy and herpes zoster. We report two cases of borderline leprosy in which the skin lesions characteristically spared the healed zoster scar. Possible mechanisms and relationship are discussed.

Paucibacillary multidrug therapy in leprosy. 7 1/2 years experience.
Three hundred and twenty-three paucibacillary (PB) leprosy patients were treated with WHO-recommended multidrug therapy (MDT) and followed up for over 7 1/2 years. The paucibacillary MDT regimen (PBR) was well accepted and tolerated. Complete clinical regression was attained in 61.2% patients after 6 doses of PBR. Persistence of clinical activity after 6 months of therapy was associated with occurrence of type I upgrading reaction, presence of six or more patches and more than two thickened major nerve trunks. Reversal reactions were encountered in 15.9% patients, one third of which were accompanied by severe neuritis. Delayed upgrading reaction occurred in six patients, two patients had relapse one and two years after stopping of PBR. The WHO recommended MDT regimen for paucibacillary cases needs careful evaluation and it may be necessary to extend the treatment beyond six months in certain situations.

Effect of clofazimine on eye in multibacillary leprosy.
Seventy-six patients of multibacillary leprosy received clofazimine as part of multidrug therapy (MDT) for periods ranging between 6 and 24 months. Complete ocular examination including slit lamp microscopy and examination of tears was carried out in all these patients. Reddish brown conjunctival and corneal pigmentation was seen in 46% and 53% of the patients respectively. Clofazimine crystals in tears were found in 32% of the patients. Apart from this no other eye changes or symptoms attributable to clofazimine were observed.

Leprosy, liver and jaundice.
Nine patients of leprosy, 5 BL and 4 LL who developed jaundice during the course of disease were investigated. Two LL patients developed jaundice during ENL reaction. There was slight hepatomegaly in 5 patients and moderate splenomegaly in 3 only. There was significant alterations in liver enzymes and serum bilirubin in all patients. The abnormalities of the enzymes levels persisted for abnormally long periods even when the serum bilirubin had come down and the patients had become asymptomatic. Blood for HBsAg and anti-HAV IgM was negative in all the patients except one in whom HBsAg was positive. Drugs could not be implicated as the cause of jaundice, all patients maintained recovery even after restarting antileprosy drugs. The possibility of non A, non B viruses producing hepatitis during the course of disease is brought out. Course of prolonged jaundice in leprosy is compared with other diseases which could result in a similar situation.

Short term combination therapy for paucibacillary leprosy--histological evaluation & follow-up study.
68 patients with paucibacillary disease were started on various regimes of multi drug therapy, consisting of ethionamide, rifampicin or clofazimine administered with dapsone. Serial skin biopsies were taken from 32 patients at one, two and three years and even later after the initial pre treatment biopsy. Actual material was available for study from 9 patients. All regimens were tolerated well except the one with ethionamide. However the therapeutic response was equal in all combination therapies as supported by histopathology. Compared to that with dapsone monotherapy the response was quicker with combination. Dapsone plus rifampicin combination was best tolerated and it worked out to be economical as well. No relapse was noted in any group during two or more years follow up.

The associated diseases with leprosy.
The prevalence of cutaneous, medical and surgical disorders was studied in 846 leprosy patients. Common cutaneous disorders among leprosy patients were pityriasis versicolor, tinea, pyodermas, warts, acquired ichthyosis, scabies, pediculosis and callosities. Only pityriasis versicolor had higher incidence when compared to general population. Common medical diseases were tuberculosis, infective hepatitis and diabetes mellitus. The epidemiological importance of their co-existence with leprosy is discussed and relevant literature of other diseases found to be frequently associated with leprosy is reviewed.

Eighth nerve evaluation in leprosy.
25 cases of bacillary positive leprosy patients and 25 age and sex matched controls were investigated for assessment of cochleo-vestibular status. Impaired hearing was complained of by 4 patients. None had tinnitus, dizziness or vertigo. On testing 44% patients were found to have unilateral or bilateral perceptive deafness. Specialised tests of hearing indicated that the deafness was of cochlear type. The vestibular functions were not affected. Leprosy seems to selectively involve the cochlea.

More about clofazimine--3 years experience and review of literature.
Local and systemic side effects of clofazimine in 514 Leprosy and 26 vitiligo patients who had taken the drug in different doses (100 mg to 300 mg daily) for variable periods of time. The commonest side effect noted was reddish brown pigmentation of skin in 77.8% patients. In an equal number of patients, ichthyotic changes on the peripheral parts of the body were noticed. GIT symptoms occurred only in 0.04% patients in the form of abdominal pain, epigastric distress, mild transient nausea and anorexia. Other minor side effects noted were reddish coloration of sweat, urine and tears. Schilling's, d-xylose tests and faecal fat excretion were near normal in the 21 patients in whom these parameters were done. No abnormality in the Jejunal mucosal biopsy was observed after therapy. No abnormality in the EKG or serum biochemistry occurred even after prolonged therapy. We found the drug to be very safe in the usual doses.
