Abstract
Expanded intronic G4C2 repeats in the C9ORF72 gene cause amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). These intronic repeats are translated through a non-AUG-dependent mechanism into five different dipeptide repeat proteins (DPRs), including poly-glycine-arginine (GR), which is aggregation-prone and neurotoxic. Here, we report that Kapβ2 and GR interact, co-aggregating, in cultured neurons in-vitro and CNS tissue in-vivo. Importantly, this interaction significantly decreased the risk of death of cultured GR-expressing neurons. Downregulation of Kapβ2 is detrimental to their survival, whereas increased Kapβ2 levels mitigated GR-mediated neurotoxicity. As expected, GR-expressing neurons displayed TDP-43 nuclear loss. Raising Kapβ2 levels did not restore TDP-43 into the nucleus, nor did alter the dynamic properties of GR aggregates. Overall, our findings support the design of therapeutic strategies aimed at up-regulating Kapβ2 expression levels as a potential new avenue for contrasting neurodegeneration in C9orf72-ALS/FTD.

Abstract
Human skull has always been used for victim identification in forensic odontology. The gender-dimorphic bone of the skull is the mandible. The gonial angle has frequently been investigated for gender estimation with variable results and requires further exploration. We aim to compare the efficacy of gonial angle estimation by ancient methods of lateral cephalometric tracing compared with more recent digital analysis methods for gender estimation in the Indian population. Lateral cephalograms of 191 (96 M and 95F) cases above the age of 17 years were retrieved. Cephalometric analysis of gonial angle on radiographs was done using both manual cephalometric tracing method and digitally using Adobe Photoshop software. The results were subjected to statistical analysis for evaluation. The mean gonial angle was higher in females (125.05; 123.77 and 125.28) than in males (122.583; 121.715 and 122.008) using both manual and digital methods. On applying the logistical regression analysis (LRA), the digital method showed the highest gender estimation accuracy of 60.7% followed by Burstone's analysis (57.1%) and manual conventional analysis (56.5%). Burstone's analysis (57.9%) correctly identified increased females, whereas digital analysis (62.5%) and manual conventional analysis (59.4%) accurately recognised increased males. The present study showed a higher gender estimation accuracy using digital methods as compared to manual methods, but it still lacks the credibility to be used as a sole factor for predicting the gender of an individual. Hence, a cumulative factor must be taken into consideration for gender identification which would provide more promising results.

Abstract
OBJECTIVE Angiogenesis plays a vital role at the molecular level in various inflammatory lesions, that lead to their chronicity. Oral lichen planus is an immune-mediated chronic inflammatory disorder. The angiogenetic role and exact mechanisms in oral lichen planus are still unclear due to a dearth of studies. Its clinical significance with angiogenesis also requires further elucidation necessitating a thorough review of the studies that have been conducted so far. The present review was designed to identify the dependence of oral lichen planus progression on angiogenesis which could aid in devising metronomic treatments required to halt the progression of this disease. MATERIALS AND METHODS A thorough search was made using MEDLINE by PubMed, Scopus, Google scholar, Cochrane library, and EMBASE databases. Original research articles, that immunohistochemically evaluated angiogenesis in oral lichen planus were included for review. Risk of bias was analysed for each study using Modified Newcastle-Ottawa scale and Review Manager 5.4 was used to output its result. RESULTS Twenty-nine published articles were included for data synthesis. The most commonly employed antibody was CD34, however, upregulated VEGF expression was the principal while ICAM-1, VCAM-1, and PECAM-1 were critical angiogenic factors to mediate angiogenesis in oral lichen planus. CONCLUSION The current evidence supports that angiogenesis, a fundamental pathogenetic mechanism of oral lichen planus, leads to its persistence and chronicity. However, studies with a larger sample size, standard evaluation criteria, different subtypes, and adequate follow-up are warranted.

Abstract
BACKGROUND Intraosseous mucoepidermoid carcinoma (IMEC) and Glandular odontogenic cyst (GOC) are those two pathological entities causing diagnostic dilemma due to the histopathological similarity. An accurate distinction between the two entities is difficult as both presents with a common radiological and histological similarities. The aim of our systematic review was to establish the diagnostic reliability of CRTC1/3::MAML2 gene fusion for the distinction between IMEC and GOC. METHODS A complete electronic literature search was made in MEDLINE by PubMed, Google Scholar, and EMBASE databases. Articles with keywords using molecular genetic findings of CRTC1/3::MAML2 gene fusion transcripts, IMEC and GOC were assessed and included for the systematic review. RESULTS Twelve subgroups having both qualitative and quantitative analysis revealed CRTC1/3::MAML2 sensitivity of 100% and specificity of 70.59% in differentiating GOC and IMEC. Fixed-effects model confirmed translocation-negative cases to have a decreased risk of association with IMEC (combined odds ratio 8.770, 95% confidence interval - 2.45 to 31.45, p < 0.002). CONCLUSIONS The current evidence supports that in all cases with positive gene fusion transcript of the CRTC1/3::MAML2 was specific for IMEC and was significantly differentiating it from GOC. Whereas cases of IMEC with negative gene fusion transcript pose diagnostic difficulty in differentiating from a GOC which is negative for CRTC1/3::MAML2 expression.

Abstract
A lepromatous patient treated with dapsone in the pre-MDT era to the point of smear negativity (> 6 years), relapsed 5 years after stopping treatment. He was then put on WHO-MDT for multibacillary (MB) leprosy, and was treated again; he had negative slit skin smears (3 years). He again presented with a relapse of leprosy 17 years after stopping treatment, and this time he presented with borderline leprosy in reaction.

Abstract
OBJECTIVES To assess the urinary nitric oxide metabolites in lepromatous patients in ENL (type 2 reactions) and to compare these metabolites after subsidence of reactions following antireactional therapy. Further to compare the levels in a group of lepromatous leprosy patients without reactions. DESIGN The initial urine samples were collected from lepromatous leprosy patients when they came with ENL before commencing antireactional therapy and repeat samples were taken after resolution of ENL. Morning urine samples were collected from LL patients without reactions. Nitrites and nitrates in urine were measured using commercially available kit. Mean levels of nitric oxide metabolites of LL patients with ENL and without ENL were compared by student's 't' test. The level during ENL and after resolution was compared by paired 't' test. RESULTS The nitric oxide metabolites were analyzed in 14 LL patients with ENL and after resolution of ENL and in 5 LL patients without reaction. The level of urinary nitric oxide metabolite is higher in LL patients in ENL reaction compared to LL patients without reaction (P < 0.04). These levels were reduced significantly with resolution of reaction following antireactional therapy (P < 0.004). CONCLUSION The findings of this study suggested that the NO/NOM excretion is increased in leprosy patients during ENL episodes. With antireactional therapy (steroids) and clinical improvement the levels are reduced.

Abstract
Morbidity in leprosy is almost always due to reactions. Similarly, to a great extent, deformities in leprosy are the consequence of reactions occurring both in borderline patients (type 1 or reversal reactions) and in lepromatous patients (type 2 or ENL reactions). Over the last three decades, work has centred around finding who are prone to getting the reactions, identifying the risk factors and improving the management of reactions in order to alleviate quickly the suffering and prevent and reverse nerve damage consequent to reactions. Though several new drugs have been tried and found somewhat useful, corticosteroids and thalidomide continue to be the mainstay in the management of leprosy reactions. A brief review of the current understanding is presented.

Abstract
The present article is the result of a study of the leprosy caseload in Agra City and is based on a house-to-house survey conducted during April-July 2003 in 5 areas. During the survey 198,150 persons were examined, and 287 cases were detected, giving a prevalence rate of 14.5/10,000. A majority of them (92%) were new cases, detected and diagnosed for the first time. The patient load was found to be unevenly distributed with comparatively more number of patients in areas such as Jamuna Kinara, Shah Ganj and Lohamandi. Among the 264 newly detected cases, 14.8% were of MB type. Overall deformity of grade > or = 2 was seen in 2.8% of patients--0.4% in PB and significantly high at 18% in MB leprosy. The observations reveal that leprosy is endemic in slum areas of Agra City.

Abstract
The bacteriological index (BI) of the skin smears is traditionally one of the important parameters of assessment of severity and of progress of leprosy under multidrug therapy. The present study reports on BI clearance among 578 multibacillary treated leprosy patients and the factors that influence this clearance. The patients were treated till smear negativity or for 2 years fixed duration and their skin smears periodically examined every 6 to 12 months till negativity (and even afterwards). We confirm that bacterial clearance is a slow process. The time taken for each log-unit decline in BI is between 13.6 to 24 months probably depending on initial BI level. The rate of smear negativity appears to be dependent on immune competence of the patients as reflected by a rapid BI decline in borderline BT-BB patients vis-à-vis BL-LL lepromatous patients both in the low and high BI group. Patients who had several episodes of ENL, took significantly longer time (63.7 months versus 53.5 months, p<0.0001) to become smear negative than those without ENL.

Abstract
The immune responses of 19 treated lepromatous patients who had remained smear negative for a long period were assessed for specific cell-mediated immunity (CMI), anti-Mycobacterium leprae antibodies and cytokine release in response to challenge with M. leprae soluble antigen (MLSA). All of these patients remained anergic to Mitsuda lepromin. Lymphoproliferation in response to M. leprae antigen was noted in only two patients. Significant reduction in the phenolic glycolipid I (PGL-I) antibody response in treated patients with no difference in the M. leprae 35-kDa antibody response was observed when these responses were compared with those of active lepromatous patients. More treated patients produced interleukin-2 (IL-2) and interferon gamma (IFN-gamma) than did active patients. On the other hand, fewer treated patients produced IL-10 than did active patients. These limited findings suggest that the host immune response makes an attempt toward upregulation of CMI in some treated LL/BL patients.

Abstract
This population sample survey conducted in rural and urban areas of the Agra District in India showed an active leprosy caseload of 60.1/10,000 in the rural and 39.1/10,000 in the urban areas against a targeted prevalence of < 1/10,000. The disease appeared to be widespread since almost 65% of the villages or urban pockets surveyed had at least one prevalent case of leprosy. Significantly larger numbers of leprosy patients were found among males, agricultural/manual workers, persons with no formal schooling, individuals living in unkept households with dirty surroundings, and among those living in dark and poorly ventilated houses. The epidemiological significance of this study reveals the endemic nature of leprosy in Agra and suggests the need to intensify and widen case-detection activities to achieve leprosy control.

Abstract
Rehabilitation experts have been addressing the problem of accommodating disabled workers in the workplace for many years. When these disabled workers return to work, accomplishing the tasks they performed prior to their disability can present a serious challenge. Meeting this challenge successfully requires that employers provide accommodations at the workplace so that the disabled workers can continue to contribute efficiently to the operation of the enterprise. Disabilities that are caused by amputations are quite critical. The severity of the injury in terms of loss of a limb and the costs associated with accommodations make this type of disability extremely significant. This paper deals with accommodating "permanent partial" and "permanent total disabilities" due to amputations. The paper is divided into two main parts. The first part focuses on the causes of amputations, types, and difficulties that an amputee faces in the work environment. In this part, an understanding of the amputee physiology has been developed. The second part of the paper addresses the various measures that employers may take in accommodating the amputees at the workplace. Design guidelines are provided to make the workplace suitable for the amputees.

Two groups of MB leprosy patients, one treated to the point of smear negativity (TSN) and the other given therapy for fixed duration (24 doses of WHO MB regimen) (FDT), were compared for relapse rates during treatment and in the post-treatment period. During the follow-up of 980.2 person years in 260 patients treated with FDT, 20 relapses (2.04/100 patient years) were observed. In the other group of 301 patients, who received therapy till smear negativity, 12 relapses in 1085.46 person years (1.10/100 patient years) occurred. Comparison of survival rates (without relapse) has shown that although there is no difference up to 4 years, the risk of relapse was significantly higher on longer follow-up in the FDT group. In addition, when patients were compared on the basis of initial bacterial load, it was found that the relapse rates in patients with BI > or = 4 was significantly higher (P < 0.01) in the FDT group as compared to those receiving treatment till the point of smear negativity (4.29 versus 1.27/100 patient years). All the relapsed patients responded to retreatment with the same drug combination, indicating that the exacerbation in their condition was because of insufficient treatment. It is suggested that to prevent or reduce relapses, treatment where feasible would be continued till smear negativity, at least in patients with high BI.

Abstract
Clofazimine is an important and effective constituent of multi drug therapy for leprosy. A study has been conducted to determine the distribution of clofazimine in maternal milk so that the safety of breast-feeding during maternal ingestion of the drug can be ascertained. Eight female leprosy patients (LL/BL) on clofazimine, 50 mg daily or 100 mg on alternate days for 1-18 months, (mean 5.0 +/- 1.81 months; median 3.25 months) and in the early lactating phase were studied. Blood samples and milk specimens were collected 4-6 hr after the last daily dose. Clofazimine was assayed in the milk and plasma samples by HPTLC. Mean plasma and milk clofazimine levels were 0.9 +/- 0.03 micrograms/ml and 1.33 +/- 0.09 micrograms/ml respectively. The ratio of milk to plasma drug concentration ranged from 1.0 to 1.7 with a mean of 1.48 +/- 0.08. The amount of drug ingested by the infants was 0.199 +/- 0.013 mg/kg/day which represented 22.1 +/- 1.9% of the maternal dose.

Abstract
An attempt has been made to definite the levels of "protective sensibility" in terms of perception thresholds to monofilament nylon induced touch/pressure stimuli. Certain problems were observed while interpreting the observations. There appears to be a range of threshold values instead of a clear cut-off point. We suggest that a monofilament nylon stimulus two times the normal threshold value for that patient be taken as cut-off point. This will make the observations of Birke and Sims (1986) and Hammond and Klenerman (1987) reasonable without having any need to exclude the cases who defy the boundaries laid by them. Since the genesis of plantar ulcer is multifactorial, it appears logical to include all patients who have a certain degree of hypoaesthesia, for special ulcer care program. The likely problems while using monofilament nylons in the field and their possible solutions have also been outlined.

Abstract
Sixteen neuritic cases have been seen developing cutaneous lesions. These cutaneous lesions by and large appear within 4 months after the diagnosis of neuritic leprosy. Leprosy pathology in cutaneous lesions has been found ranging between indeterminate and borderline lepromatous group. Development of cutaneous lesions does not seem to be influenced by age, sex or number of nerves or lepromin status. Neither lesions seem to appear in any particular part of the body. Therapy, duration and type i.e. monodrug or multidrug, also does not seem to influence the development of cutaneous lesions in either way. It appears that neuritic cases with either very early (indeterminate) or with advanced multibacillary neural pathology may develop skin lesions. Skin lesion possibly appear following reversal reaction in skin. Cases with newly developed skin lesions well respond to standard therapy. Development of cutaneous lesions by neuritic cases possibly indicates towards the natural history of the disease, conforming to the hypothesis that leprosy is basically neural in inception and that all other forms emerge from it.

Abstract
The threshold to touch was tested in hands and feet of normal persons using Semmes-Weinstein graded monofilament nylons. The minimum stimulus to which response could be elicited was nylon number 3.61 in palms and 4.31 in soles. These numbers relate to the logarithm of the force applied, 3.61 corresponding to 0.217 gm force and 4.31 to 2.35 gm force respectively. The area of pain insensitivity complained by the patient more or less corresponds to that revealed by objective testing. It was interesting to observe that loss of pain sensitivity was confined to a smaller area compared to touch and thermal insensibility in the part innervated by the same nerve trunk.

Abstract
Trigeminal neuralgia is a well recognized clinical entity. However, it has not been reported to mimic leprosy or vice versa. Of the 3 cases reported here, 2 initially presented with neuralgic symptoms similar to that seen in trigeminal neuralgia and later developed borderline lesions on the face. The 3rd case demonstrated a tingling sensation along with firm and palpable supraorbital nerve (a branch of trigeminal nerve), and a very early skin lesion on the face pointed to the need to consider neuritic type leprosy before concluding the final diagnosis of a disease like trigeminal neuralgia which calls for a different therapeutic approach.

Abstract
We observed 29 patients presenting with vague peripheral neurological symptoms for 6 months or more. During this period, 16 developed clinical leprosy, 3 developed borderline tuberculoid leprosy and the other 13 developed neuritic leprosy. Of these 13 cases 11 subsequently developed skin lesions similar to those seen in indeterminate and in borderline tuberculoid leprosy. Based on the above observations, an attempt has been made to explain the evolution of early lesions of leprosy.

Abstract
This study describes a comparative evaluation of dapsone kinetics in humans on administration of Dapsomine, a capsule containing dapsone 100 mg dispersed in oily-base suspension of clofazimine 50 mg. Seven untreated lepromatous leprosy patients were given one capsule of Dapsomine a day for seven days and the pharmacokinetics parameters in this group were compared with those from another group of seven patients who received dapsone 100 mg and clofazimine 50 mg separately. There were no statistically significant differences in parameters such as peak dapsone plasma concentration (Cmax), basal plasma level (C24h), time to peak level (tmax), absorption half-life (t1/2 alpha), elimination half-life t1/2 beta) and areas under plasma concentration-time curves (AUC0-8h) and AUC0-24h) between the two groups.

Abstract
A patient of lepromatous leprosy, who received a high dose of clofazimine as part of multidrug therapy, for chronic erythema nodosum leprosum (ENL) had frequent 'haemoptysis'. The haemoptysis was later found to be due to expectoration of clofazimine. This interesting, and perhaps first case of such an occurrence, is reported.

Abstract
A comparison was made of the numbers of epidermal Langerhans cells in active and regressed lesions of tuberculoid and lepromatous leprosy using the OKT6 and OKIa monoclonal antibodies. A reduction in the numbers of CD1+ epidermal Langerhans cells was noticed in the regressed lesions of both the tuberculoid and lepromatous leprosy lesions unlike the active lesions. The majority of infiltrates in both types of regressed lesions were HLA-DR+ and CD1-.

Abstract
Immunohistological analysis of infiltrates of nerves in patients with neuritic leprosy was carried out using monoclonal antibodies defining T cell subsets, Langerhans cells, HLA DR antigens, and indirect immunofluorescence. In all, eight nerves were analyzed. 2 of the 8 nerves showed epithelioid cell granulomas surrounded by large numbers of lymphocytes. The predominant lymphocytes in these granulomas were activated T cells expressing CD3 and HLA DR antigens. The proportion of CD3+ and CD4+ cells was higher than that of CD8+ cells. The ratio of CD4+/CD8+ cells in these two biopsy specimens was 5.6 and 1.5, respectively. In these nerves CD4+ cells were diffusely scattered into epithelioid cell granulomas, while CD8+ cells were localized at the periphery of the granuloma. The remaining six nerves showed macrophages containing numerous bacilli, and a few lymphocytes and plasma cells diffusely distributed into the granuloma. In these nerves, only occasional lymphocytes expressing CD3 or CD4 or CD8 and HLA DR antigens were noticed. In two fo the biopsy specimens, a small proportion of CD8+ cells were visualized. Macrophages and Schwann cells were HLA DR+ in all nerves. CD1+ cells were not seen in the infiltrates of any of these nerves. A similar pattern and distribution of cells was noticed in the nerve granulomas of tuberculoid and lepromatous leprosy. These findings suggest that the mechanisms of nerve damage in the patients with neuritic leprosy could be either immunological or non-immunological, depending on the nature and characteristics of the infiltrates.

Abstract
Sera from 478 persons (348 leprosy patients, 33 tuberculosis patients, 29 healthy contacts of leprosy patients, 38 normal healthy Indians, and 30 normal healthy Europeans) were screened for anti-HIV-1 IgG antibodies by ELISA. None was positive. In addition, 132 samples (from 43 leprosy patients, 21 tuberculosis patients, 5 healthy contacts of leprosy patients, 33 normal healthy Indians, and 30 normal healthy Europeans) were also tested by Western blot assay for anti-HIV-1 IgG antibodies. Only 1 of the 63 healthy subjects expressed a prominent p17 band. One or more bands were found in 44 (leprosy patients 33/43, tuberculosis patients 7/21, and leprosy contacts 4/5) of the remaining 69 sera. Antibody to the HIV-1-specific antigen p24 was expressed by 17 of these subjects (14/43 leprosy patients, 1/21 tuberculosis patients, and 2/5 leprosy contacts), either as a single band or in combination with other bands. This raises the possibility of a common antigenic pattern between HIV-1 and mycobacteria, especially Mycobacterium leprae.

Abstract
Regularity of DDS intake among 366 leprosy patients attending our out patient department voluntarily was assessed by urine spot test. It was found that only 54.6% of them had taken their last dose of drug within the previous three days. Those who kept their appointment showed better compliance than those who did not. Urinary DDS positivity was found to be unrelated to sex, occupation or the type of the disease. In the younger age group the compliance was low, as also among the patients coming from nearby places as compared to those who were residing in far off districts.

Abstract
Langerhans cells (LC) were defined by indirect immunofluoresence using OKT6 monoclonal antibody in the skin lesions of 11 untreated patients with tinea corporis. The number and distribution of OKr6 + epidermal LC in the lesions was very low in comparison to that found in the normal skin. In most of the lesions, T6 + LC could not be seen in the epidermis. A like antigens were not detectable on the keratinocytes. These observations suggest deceased CMI response to the fungal infection and that the reduction in LC may be a contributing factor in the pathogenesis of tinea corporis.

Abstract
A study has been undertaken wherein (TT/BT) cases with less than 5 lesions have been given DDS for 12 months alone or in combination with steroids for initial 1 month or rifampicin for initial one week. It has been found that only about three fourths of the cases become disease inactive in 12 months period. Follow up of 15 to 21 months in the post treatment period has shown a relapse rate of 6.33 per 1000 patient months. There was no difference in number of relapses occurring in the three regimens i.e. with or without rifampicin. Half the relapses were primarily in the nerves. During the course of treatment, a slightly higher number of patient in the DDS group had nerve problems as compared to group wherein additional steroids had been given.

Abstract
To study the effect of prothionamide. on the infectivity of untreated lepromatous patients 20 cases were randomly given either 250 mg or 500 mg prothionamide monotherapy daily for 2 months. All patients tolerated the drug well. Clinical improvement with healing of mucosal ulcers was seen in 13 of the 16 cases. Nasal smears become negative in all the cases within 2 months. Mouse footpad inoculation done from biopsy specimens/skin scrape suspension- s became non infective to mice in all the cases within the trial period. There was a substantial reduction in ,the MI and histopathology showed complete fragmentation of the bacilli with a significant increase in the lymphocyte content. The -findings suggest a rapid bactericidal effect and a similar, use fullness on both the doses of the drug for the treatment of multibacillary leprosy.

Abstract
With an aim to reduce the length of treatment of leprosy, as a first step an investigation has been undertaken to evaluate the efficacy of maintenance therapy in non-lepromatous cases. Relapse rates in a group of 47 cases, in whom treatment had been given only til the point of inactivity (the trial group) have been compared with a similar group of 27 cases who received additional 18 months maintenance therapy (the control group). No difference in relapse rates has been found (2.13 per 1000 patient months in trial group as against 2.58 per 1000 patient months in the control group). This suggests that additional 18 months maintenance therapy, as is currently recommended, does not offer any additional advantage in reducing the relapses.

Abstract
Anorectics are clinically used in the management of obesity to accept dietary restriction through decreased desire of food intake. The present study, indicates that the drug SK & F 38393 a dopamine agonist given to albino rats at the doses of 1 mg/kg and 5 mg/kg caused decreased food intake. Central side effects observed with amphetamine and other related drugs were not observed with this drug. The drug thus may be used as an anorectic agent without central side effects.

Abstract
A quantitative estimation of discharge of M. leprae in the milk of 39 leprosy female patients has been made. Twelve of the 39 patients (10 LL/BL and 1 each of T/BT and BB) showed bacilli in their milk. Only one of these patients was on treatment. AFB count in 10 ml of milk was found to range from 4.3 X 10(4) to 4.3 X 10(5). Significance of discharge of such a large number of bacilli in breast milk is discussed.

Abstract
22 Adult Male Lepromatous patients suffering from recurrent lepra reaction have been allotted to either a regimen of combined treatment with Clofazimine and Thalidomide alone. The initial dosage of either of the drugs was 300 mg daily administered in divided doses of 100 mg three times a day. The preliminary assessment of the ongoing study, indicates that the combined treatment controls the reactional state more rapidly than monotherapy with Thalidomide alone. Results of treatment as regards relief of neuritis and arthritis are particularly gratifying. Four month.ases relapsed into reactional status from 2 days to 15 days. 5 cases on the combined therapy relapsed from one to three months. Three other cases required six months and three cases 8 months treatment before clofazimine could be withdrawn. It would appear that a maintenance therapy of 6 months with flofazimine would be necessary for maintaining the control of reactional episodes while employing this combined therapy.
