Abstract
The 3-Hydroxy Benzaldehyde-N-methyl 4-Stilbazolium Tosylate (3- HBST) is a new organic NLO crystal and it is a new derivative in stilbazolium tosylate family. In this work we have synthesized 3-HBST and the single crystal was grown by conventional slow cooling method. The structure and lattice parameters of the grown crystal were determined by the single crystal X-ray diffraction (XRD) technique and it is exhibiting good crystalline nature which is observed from the powder XRD. In order to check the crystalline quality the rocking curve was recorded using multi crystal X-ray diffractometer. The functional groups were identified from both FTIR and NMR spectral analyses. The π-π* and n-π* optical transition energy levels were estimated from the absorption peaks. The NLO property was confirmed by measuring relative SHG efficiency by Kurtz powder test; it shows 24 times higher SHG efficiency than that of urea. In order to test the mechanical stability the Vickers and Knoop micro hardness measurement were carried out and found that the micro hardness number decreases with increasing load. The melting point was determined from Differential Scanning Colorimetry (DSC).

Abstract
Onychomycosis is a common chronic nail disorder where dermatophytes are the predominant pathogens. However, non-dermatophytic moulds like Aspergillus can also be implicated as the causative agents. Herein, we report a rare case of onychomycosis due to Emericella quadrilineata ( Aspergillus tetrazonus) in an apparently immunocompetent host.

Abstract
BACKGROUND & OBJECTIVES Leprosy type 1 reactions (T1R) are acute episodes of immune exacerbation that are a major cause of inflammation and nerve damage. T1R are diagnosed clinically and supported by histopathology. No laboratory marker is currently available that can accurately predict a T1R. Increased plasma and tissue expression of inducible nitric oxide synthase (i-NOS) and chemokine CXCL10 have been demonstrated in T1R. We studied the gene expression and immunoexpression of i-NOS, CXCL10 and its receptor CXCR3 in clinically and histopathologically confirmed patients with T1R and compared with non-reactional leprosy patients to understand which biomarker has better potential in distinguishing reaction from non-reaction. METHODS Gene expression of i-NOS, CXCL10 and CXCR3 was studied in 30 skin biopsies obtained from patients with borderline tuberculoid (BT), mid-borderline (BB) and borderline lepromatous (BL) leprosy with and without T1R by real-time PCR. Further validation was done by immunohistochemical expression on 60 borderline leprosy biopsies with and without T1R. RESULTS Of the 120 patients histopathological evaluation confirmed T1R in 65 (54.2%) patients. CXCR3 gene expression was significantly (P<0.05) higher in BT- and BB-T1R patients compared to those without T1R. The CXCL10 gene expression was significantly higher (P<0.05) in BB leprosy with T1R but the difference was not significant in patients with BT with or without T1R. Immunoexpression for CXCR3 was significant in both BB-T1R and BB (P<0.001) and BT and BT-T1R (P<0.001). Immunoexpression of CXL10 was significant only in differentiating BB from BB-T1R leprosy (P<0.01) and not the BT cases. i-NOS immunoexpression was not useful in differentiating reactional from non-reactional leprosy. INTERPRETATION & CONCLUSIONS Both CXCL10 and CXCR3 appeared to be useful in differentiating T1R reaction in borderline leprosy while CXCR3 alone differentiated BT from BT-T1R. CXCR3 may be a potentially useful immunohistochemical marker to predict an impending T1R.

Abstract
Toxicity of conventional (profenofos 50 EC and λ-cyhalothrin 5 EC) and non-conventional (flubendiamide 480 SC, chlorantraniliprole 18.5 SC, emamectin benzoate 5 SG) insecticides was determined on the basis of median lethal concentration (LC50) values on third instar larvae of jute hairy caterpillar, Spilarctia obliqua under laboratory conditions. Further, the promising binary insecticides combinations with lesser LC50 values and adequate synergistic activity were evaluated under field conditions. The LC50 values calculated for insecticides viz., chlorantraniliprole, flubendiamide emamectin benzoate, λ-cyhalothrin and profenophos were 0.212, 0.232, 0.511, 0.985 and 3.263 ppm, respectively. Likewise, the LC50 values for flubendiamide with λ-cyhalothrin in 3:1 proportion was most toxic (0.103 ppm) amongst all the other binary combinations with λ-cyhalothrin. Chlorantraniliprole in combination with λ-cyhalothrin at 1:1 proportion (0.209 ppm) was most toxic followed by 3:1 proportion (0.345 ppm). Similarly, emamectin benzoate in combination with λ-cyhalothrin at 1:1 proportion was more toxic (0.271 ppm) than 3:1 ratio (0.333 ppm). Toxicity index of flubendiamide + λ-cyhalothrin (3:1 ratio) was highest (970.87). Bioefficacy of synergistic binary combinations along with individual insecticides established the superiority of profenophos + λ-cyhalothrin (3:1) with 89.12% reduction in infestation and recorded maximum fibre yield 38.67qha' under field condition. Moreover, combination of diverse insecticides group might sustain toxicity against the target insect for longer period with least probability of resistance development.

Abstract
Background Patients with Post kala-azar dermal leishmaniasis (PKDL) are considered a reservoir of Leishmania donovani. It is imperative to identify and treat them early for control of visceral leishmaniasis (VL), a current priority in the Indian subcontinent. We explored trends in clinico-epidemiological features of PKDL cases over last two decades, for improving management of the disease. Methods Clinically suspected cases were diagnosed with rK39 strip test followed by parasitological confirmation by microscopy and/or PCR/qPCR in skin tissue/slit aspirates. Patients were treated with antimonials till 2008 and subsequently with miltefosine. Results The study indicated higher incidence of PKDL cases in areas of high endemicity for VL, with 20 % cases reporting no history of VL. Approximately 26 % cases of PKDL were initially misdiagnosed at primary health centers. Duration between onset of PKDL and diagnosis was above 12 months in 80 % cases. Diagnostic sensitivity was 32-36 % with microscopy and 96–100 % with PCR/qPCR. Compliance to treatment was over 85 % with miltefosine while 15 % with antimonials. Relapse rate with miltefosine was up to 13.2 %. Conclusions PKDL patients tend to delay reporting and are often misdiagnosed. Confirmatory diagnosis using minimally invasive skin slit aspirate samples would help overcome such issues. There was a paradigm shift in compliance with miltefosine; however, increasing relapse rate indicated the need for newer therapies with oral formulations.

Abstract
Background Recent studies have shown significant decline in the final cure rate after miltefosine treatment in visceral leishmaniasis. This study evaluates the efficacy of miltefosine in the treatment of post kala-azar dermal leishmaniasis (PKDL) patients recruited over a period of 5 years with 18 months of follow-up. Methodology In this study 86 confirmed cases of PKDL were treated with two different dosage regimens of miltefosine (Regimen I- 50mg twice daily for 90 days and Regimen II- 50 mg thrice for 60 days) and the clinical outcome assessed monthly. Cure/relapse was ascertained by clinical and histopathological examination, and measuring parasite burden by quantitative real-time PCR. In vitro susceptibility of parasites towards miltefosine was estimated at both promastigote and amastigote stages. Results Seventy three of eighty six patients completed the treatment and achieved clinical cure. Approximately 4% (3/73) patients relapsed by the end of 12 months follow-up, while a total of 15% (11/73) relapsed by the end of 18 months. Relapse rate was significantly higher in regimen II (31%) compared to regimen I (10.5%)(P<0.005). Parasite load at the pre-treatment stage was significantly higher (P<0.005) in cases that relapsed compared to the cases that remained cured. In vitro susceptibility towards miltefosine of parasites isolated after relapse was significantly lower (>2 fold) in comparison with the pre-treatment isolates (P<0.005). Conclusion Relapse rate in PKDL following miltefosine treatment has increased substantially, indicating the need of introducing alternate drugs/ combination therapy with miltefosine. Increasing resistance to antimonials has paved the way for the oral drug miltefosine for PKDL treatment. Recent studies show a significant decline in the final cure rate of VL after miltefosine treatment in the Indian subcontinent. This is the first study to evaluate the efficacy of miltefosine treatment in a large number of PKDL cases with 18 months follow-up. PKDL cases that completed miltefosine treatment responded well and showed initial cure; however, with 18 months of follow up period, the final cure rate was only about 85%. Treatment regimen based on high dosage over short duration resulted in high relapse rate. We observed that the parasites isolated from the cases that relapsed were more tolerant to miltefosine (>2 fold) compared to the isolates from pre-treatment stage. Estimation of parasite load at pre-treatment stage indicated that the patients with higher initial parasitic burden were at a higher risk of relapse. The declining efficacy of monotherapy with miltefosine warrants the need of alternate regimens for treatment of PKDL.

Abstract
We present a rare case of a 30-year-old woman who presented with a swelling on the lateral aspect of her left forearm, present since 6 months, adjacent to a 16-year-old burn scar. X-ray of elbow joint and forearm revealed the subcutaneous nature of the swelling. Giemsa and periodic acid-Schiff-stained smears and potassium hydroxide mount of fine-needle aspirate of the swelling revealed dematiaceous, branching, and septate fungal hyphae. Fungal culture of the aspirated pus showed growth of Exophiala jeanselmei. Histopathological examination revealed brown-coloured hyphae with foreign body giant cell reaction and palisading granulomas in the surrounding tissue. The patient was successfully treated with surgical excision of the swelling. All the cases of phaeohyphomycosis due to Exophiala spp. in India are also reviewed.

Abstract
BACKGROUND Post kala azar dermal leishmaniasis (PKDL) is a sequel to visceral leishmaniasis or kala azar seen predominantly in the Indian subcontinent and Africa. Histopathological descriptions of the condition are limited. METHODS Biopsies of 88 skin and 16 mucosal lesions were evaluated for histopathological findings on formalin-fixed, paraffin-embedded tissues. RESULTS There were 71 (80.7%) males and 17 (19.3%) females with a mean age of 24.8 and 28.5 years, respectively. A past history of kala azar was present in 64 (72.7%) patients and post kala azar dermal leishmaniasis developed a mean of 6.2 years after visceral leishmaniasis. Of the biopsies studied, the clinical lesions were macular in 14 (15.9%), papulo-nodular in 32 (36.3%) and showed both macules and papulo-nodules in 42 (47.8%). Follicular plugging was a common epidermal finding. A clear Grenz zone was frequently noted. The dermal infiltrates were arranged mainly in three patterns: superficial perivascular infiltrates in 16 (18.1%), perivascular and perifollicular infiltrates in 24 (27.3%) and diffuse infiltrates in 41 (46.6%) biopsies. Leishman-Donovan (LD) bodies were noted in 13 (44.9%) of 69 cases on slit-skin smear and in 25 (28.4%) of 88 biopsies. In 16 patients, where both skin and mucosal biopsies were available, LD bodies were identified in 10 (62.5%) mucosal biopsies as compared to 3 (18.7%) skin biopsies. LIMITATIONS The retrospective nature of the study and the lack of controls were limitations. CONCLUSION The various histomorphological patterns of post kala azar dermal leishmaniasis are a useful clue to the diagnosis even when LD bodies have not been detected. This study also suggests that LD bodies are more frequently seen in mucosal biopsies in comparison to cutaneous biopsies.

Abstract
BACKGROUND Rheumatoid arthritis is a chronic and systemic inflammatory disorder, in which Lipoprotein (a) [Lp (a)] increases plaque formation and thus promotes atherosclerosis. Coronary artery disease is one of the co-morbidity in rheumatoid arthritis patients. AIM The aim of this study is to evaluate Lp (a) as a cardiovascular risk factor in patients with rheumatoid arthritis. This was a comparative study in which Lp (a) and lipid profile were compared in rheumatoid arthritis patients and controls. MATERIALS AND METHODS The study included 30 sero-positive rheumatoid arthritis patients and 30 normal healthy subjects with an age and sex matched group of 25-80 years. Statistical analysis was performed using SPSS version 17. RESULTS Serum Lp (a) concentration was significantly increased (P < 0.001) in rheumatoid arthritis patients compared with controls. Serum high-density lipoprotein-cholesterol was significantly lowered (P < 0.05) in patients as compared to controls. There was no significant difference in serum total cholesterol, triglycerides, and very low density lipoprotein-cholesterol between patients and controls. CONCLUSION The findings indicate that the patients with rheumatoid arthritis are at high risk of developing cardiovascular disease in future due to the increased level of Lp (a). In addition to conventional lipid profile, estimation of Lp (a) can prove to be a valuable tool in risk assessment of population in general and management of disease in particular.

Abstract
Background: Neonatal jaundice refers to yellow coloration of the skin and the sclera (whites of the eyes) of newborn babies that result from the accumulation of bilirubin in the skin and mucous membranes. Because bilirubin is potentially toxic to the central nervous system. Genetic disorders of bilirubin conjugation, particularly the common Gilbert's syndrome, can also contribute to neonatal hyperbilirubinemia. Objective: The aim of this study was to evaluate the lipid per-oxidation and antioxidant enzyme activities in patients with neonatal jaundice before and after phototherapy. Materials and Methods: The study includes 50 neonatal jaundice patients with average age 2-15 days. All patients of neonatal jaundice receiving phototherapy except feeding, cleaning. Subjects selected were from the patients attending Pediatrics Department. Plasma malondialdehyde (MDA), erythrocyte glutathione peroxidase (GPX), superoxide dismutase and catalase (CAT) to monitor the bilirubin level. Results: The results show increased levels of bilirubin compared with controls (P < 0.001) shows the level of plasma MDA in control, before and after phototherapy. Represents the level of GPX was significantly increased in after the phototherapy group when compared with before phototherapy and control SPSS soft ware: (P < 0.001). Shows the reduced glutathione (GSH) level in plasma was significantly decreased in the after phototherapy group when compared with before phototherapy and control (P < 0.001). And finally with ascorbic acid and CAT. Conclusion: It is evident from the study that increased oxidative stress in neonatal jaundice babies leads to decrease in the levels of antioxidants like GSH and ascorbic acid and disturb their metabolism, that weaken their ability to fight the growing stress. Intense oxidative stress and decreased antioxidants may contribute to neural cell death and alter the erythrocytomembrane structure processing in neonatal jaundice.

Abstract
This report describes 6 HIV-negative patients including 5 children with scrofuloderma and an adult with lupus vulgaris, out of a total of 303 cases of cutaneous tuberculosis seen during a 4½-year period, who showed a positive tuberculin test and granulomatous histopathology, but failed to respond to first-line antitubercular therapy. They were suspected to have multidrug-resistant infection as no other cause could be ascertained. Tissue aspirate or biopsy was sent for histopathology and culture. Mycobacterium tuberculosis was isolated from the aspirate in three patients and sputum in one with associated pulmonary tuberculosis. Drug susceptibility tests showed that all isolates were resistant to rifampicin and isoniazid, and one each additionally to streptomycin and ethambutol, respectively. In two, culture was unsuccessful. All were administered second-line antitubercular drugs. Clinical improvement was appreciable within 2 months as weight gain, and regression of ulcers, swellings and plaques. Two completed the recommended 24 months of therapy. Multidrug-resistant cutaneous tuberculosis should be suspected in patients with no response to first-line drugs, with clinical deterioration, and where other causes of treatment failure are not forthcoming. Owing to poor isolation rates on culture and low sensitivity of molecular tests, in such cases, a trial of second-line anti-tubercular drugs may be justified for a reasonable period of 2 months. Where facilities permit, culture and drug sensitivity tests should be done before starting treatment. Culture positivity is better from aspirated material.

Abstract
BACKGROUND Cancer is a disease that evokes wide spread fear among people and is one of the leading causes of deaths in the world. Diethylnitrosamine (DEN) is a known carcinogen in rodent liver. DENs reported to undergo metabolic activation by cytochrome P450 enzymes to form reactive electrophiles that cause oxidative stress leading to cytotoxicity, mutagenicity and carcinogenicity. OBJECTIVE The present study was carried out to evaluate the antioxidant activity of ethanolic extract of Tinospora cordifolia (EETC) in N-nitrosodiethylamine (DEN) induced liver cancer in male Wister albino rats. MATERIALS AND METHODS The antioxidant activity was assessed by the levels of lipid peroxidation (LPO), enzymic and nonenzymic antioxidants. RESULT A significant levels of LPO was increased as the enzymic and nonenzymic antioxidants values were decreased in liver cancer bearing animals. CONCLUSIONS The administration of EETC to cancer bearing animals reverted the LPO levels, enzymic and nonenzymic antioxidants to near normal.

Abstract
Upgrading typel lepra reaction or reversal reaction (RR) is an acute inflammatory complication of leprosy and a disparity exists between clinicians and pathologists for diagnosing a RR. Inter-observer variations among pathologists also compound this problem as no universally agreed diagnostic criteria exist. 120 biopsies and H&E stained slides were assessed by 3 pathologists. The pathologists were blinded to the clinical diagnosis and to each other's observations. Each pathologist assigned a likelihood of reaction by their histopathological observations as definitely reaction, probable reaction and no reaction. Clinicopathological correlation and interobserver agreement was analyzed statistically. Discordance between clinical and histopathological diagnosis was seen in 30.8% by pathologist 1 (P1), 23.7% by pathologist 2 (P2) and 34.5% bythe pathologist 3 (P3). Dermal edema, intragranuloma edema and epidermal erosion were consistent findings by all observers. Definite reaction was seen in 54.2% of cases by P1, 53.3% by P2 and 34.5% by P3. Kappa statistics for strength of agreement showed good agreement between 3 pathologists with P1 (κ = 0.83), P2 (κ = 0.61), P3 (κ = 0.62). RR are underdiagnosed on histopathological examination but this study shows that dermal edema, edema within the granuloma and partial obliteration of grenz zone by granuloma are reliable clues to diagnose a RR on histopathology.

Abstract
Mutations in STXBP1 have recently been identified as a cause of infantile epileptic encephalopathy. The underlying mechanism of the disorder remains unclear and, recently, several case reports have described broad and progressive neurological phenotypes in addition to early-onset epilepsy. Herein, we describe a patient with early-onset epilepsy who subsequently developed a progressive neurological phenotype including parkinsonism in her early teens. A de novo mutation in STXBP1 (c.416C>T, p.(Pro139Leu)) was detected with exome sequencing together with profound impairment of complex I of the mitochondrial respiratory chain on muscle biopsy. These findings implicate a secondary impairment of mitochondrial function in the progressive nature of the disease phenotype.

Abstract
Background: Xylene is used as a clearing agent in hematoxylin and eosin (H and E) staining of tissue sections in routine histopathology based diagnosis. However, the hazards associated with exposure to xylene are of concern. Numerous solutions mainly essential oils have been evaluated in the past as clearing agents, which can possibly be substituted for xylene during the routine tissue processing. Aim: The aim of this study is to compare the efficacy of essential oil (cedarwood oil), as a possible replacement for xylene in H and E staining procedures. Materials and Methods: The study was carried out in the Department of Oral Pathology and Microbiology. Thirty paraffin blocks of the routine biopsy specimen were retrieved from the department archives. The cedarwood oil was procured from organic and essential oil dealer in the local market. Two to three paraffin sections of four micron thickness were cut from each of the 30 paraffin blocks of processed tissue specimens, were subjected to different clearing agents: Essential oil (8% cedarwood oil) or xylene and stained with H and E stain. The stained sections were scored based on nuclear and cytoplasmic details, clarity and uniformity of staining. Results: Significant correlation was observed between cedarwood oil and xylene in terms of the three staining quality parameters assessed. Conclusions: We conclude that cedarwood oil can be an effective, eco-friendly and safe alternative to xylene as a clearing agent in the histopathological laboratory.

Abstract
Ameloblastoma is usually considered a homogenous neoplasm and is thought of as the most primitive of all odontogenic neoplasms. However, detailed investigations have proven clinicopathological diversity in a significant number of cases, thus mounting the evidence in favor of considering ameloblastoma as a mysterious lesion. The purpose of this article is to report a unique case of desmoplastic ameloblastoma and to throw light on the atypical changes noticed in the stromal component. The findings of this case have served to add interesting parameters to the study of stromal changes associated with this perplexing odontogenic tumor.

Abstract
It is important for dermatologists to be aware of cutaneous changes related to religious practices to help in their recognition and management. The anatomic location of cutaneous lesions associated with friction from praying varies based on religious practice. Allergic contact dermatitis from products and substances commonly used in worshipping also vary by religion. Some religious practices may render individuals prone to infections that manifest on the skin. Tattoos of godly figures also may adorn the body. Religious practices also have been implicated in cases of urticaria, köbnerization, and leukoderma. This article reviews the clinical presentation of some of the most common cutaneous changes that occur in individuals who practice the following religions: Christianity, Islam, Judaism, Hinduism, and Sikhism.

Abstract
Myxoinflammatory fibroblastic sarcoma is a low grade sarcoma that is composed of a mixed inflammatory infiltrate along with spindled, epithelioid and bizarre appearing cells in a background of hyaline and myxoid zones. Seen affecting the distal extremities commonly, with an equal sex predilection, these tumors are rare and require an extensive immunohistochemical work up for proper diagnosis. They have a tendency to recur.

Abstract
This study is focused on the recovery and recycling of plastics waste, primarily polycarbonate, poly(acrylonitrile-butadiene-styrene) and high impact polystyrene, from end-of-life waste electrical and electronic equipments. Recycling of used polycarbonate, acrylonitrile-butadiene-styrene, polycarbonate/acrylonitrile-butadiene-styrene and acrylonitrile-butadiene-styrene/high impact polystrene material was carried out using material recycling through a melt blending process. An optimized blend composition was formulated to achieve desired properties from different plastics present in the waste electrical and electronic equipments. The toughness of blended plastics was improved with the addition of 10 wt% of virgin polycarbonate and impact modifier (ethylene-acrylic ester-glycidyl methacrylate). The mechanical, thermal, dynamic-mechanical and morphological properties of recycled blend were investigated. Improved properties of blended plastics indicate better miscibility in the presence of a compatibilizer suitable for high-end application.

Abstract
The diagnosis of any pathology is fundamentally based on the microscopic structure of cells and tissues and this remains as the standard by which all other diagnostic tests are measured. In this era, the pathologists are relying on the examination of tissue section stained by histochemical means and it is supported by the advanced immunological, biochemical and molecular techniques. This review will provide the information about one of the way that can be followed to unravel the molecular mechanism in spotting the disease process. Technologies used to study the cellular process are same for the normal and the abnormal cell. Experimental strategy briefed here is also applicable for both. The cellular process can be studied either from protein to gene or from gene to protein. Earlier days biochemical analysis (isolation of protein, protein sequencing) was separate and genetic analysis (genomic mapping) was separate. But now with advent of recombinant DNA technology it is possible to have a link between the biochemical and genetic analysis. Intermediary step of development of oligonucleotide synthesis, complementary DNA probe and cloning has revolutionized the research process. Identified gene can be compared with the normal gene by comparative genomics or expressed proteins by expression proteomics.

Abstract
OBJECTIVES Post-kala-azar dermal leishmaniasis (PKDL) is well recognized in the Indian subcontinent and is not infrequently confused with leprosy. The present report describes findings in an unusual case of PKDL. METHODS We report an adult male who presented with firm nodules on the face and extremities, along with hypopigmented macules on the neck with deformity and hypoesthesia over the right upper extremity. The patient had experienced similar lesions seven years previously and had used multibacillary multi-drug therapy for leprosy with complete resolution of the nodules. RESULTS At the current presentation, skin smears from ear lobes and nodules were negative on Ziehl-Neelsen staining. Histopathological examination revealed a dermal lymphohistiocytic infiltrate with plasma cells. Giemsa staining of a tissue smear revealed Leishmania donovani bodies, and an rK39 antigen test was positive. The patient responded well to oral miltefosine. CONCLUSIONS This case is noteworthy because the patient exhibited an unusual combination of healed leprosy sequelae and active PKDL lesions, which caused a diagnostic dilemma.

Abstract
Schwannoma is an intraoral rare, benign neoplasm arising from and consisting solely of Schwann cells. Its etiology is unknown. It presents as a solitary, slow growing, smooth surfaced, generally asymptomatic firm mass. Schwannomas commonly occur between 30 and 50 years. It is relatively uncommon, although a quarter of all Schwannoma's occurs in the head and neck region. Schwannoma of the floor of the mouth is rare in the oral region. Described is a case of Schwannoma of the floor of the mouth in a 28-year-old male, of large size.
