Abstract
ELISA for anti-desmoglein antibodies (Dsg) is commonly used for diagnosis and assessment of treatment response in pemphigus vulgaris (PV). The present study was conducted to assess the relationship between salivary and serum Dsg1 and Dsg3 levels, and whether salivary Dsg1 and Dsg3 levels correlate with clinical disease severity of oral mucosal lesions in PV. In total 43, patients with PV with predominantly mucosal involvement were recruited. Both serum and salivary samples were collected from the cases, and salivary samples were also collected from five controls. There was a statistically significant correlation between serum and salivary Dsg1 levels and between serum and salivary Dsg3 levels. There was no correlation between serum or salivary Dsg1 and Dsg3 levels with the objective component of the oral mucosal Autoimmune Bullous Skin Disorder Intensity Score (ABSIS). Serum Dsg1 levels significantly correlated with cutaneous ABSIS, but there was no correlation between cutaneous ABSIS and either salivary Dsg1, salivary Dsg3 or serum Dsg3. As salivary Dsg titres correlate with serum levels, saliva can serve as a simple and noninvasive alternative to serum for Dsg ELISA.

Abstract
The objective of the present study was to investigate the effect of testicular tissue lysate (TTL) on developmental competence of germinal vesicle (GV) stage porcine oocytes. Two types of TTL were prepared through repeated freeze-thaw in liquid nitrogen, one from whole testicular tissue (wTTL) and other from either of four different sections of testes, namely just beneath the tunica albuginea (TA), from the transitional area between the seminiferous cord/tubules and the mediastinum testis (TR) and from the intermediate area (parenchymal tissue origin) and CE (cauda epididymis origin). The whole or section-wise TTL treatments were given for 44 hr during in vitro maturation (IVM). Oocyte maturation was done in either of the two media, namely defined (high-performance basic medium for porcine oocyte maturation, commercially available) and serum containing (TCM199). After maturation, oocytes were co-incubated with fresh spermatozoa for 6 hr and then transferred to embryo culture media. Treatment of GV stage oocytes with wTTL (1 mg/ml) increased the cleavage and morula percentage rate (69.23 ± 6.23 and 48.15 ± 6.77, respectively) than that of their control (58.33 ± 8.08 and 32.54 ± 5.53, respectively) in defined media, and in serum-containing media, cleavage and morula percentage rate were almost equal in both treatment (54.56 ± 7.79 and 34.70 ± 6.78, respectively) and control (59.52 ± 8.21 and 38.52 ± 6.54, respectively). However, effect of wTTL was not significant. In case of section-wise TTL supplements, TR section significantly (p < .01) improved cleavage and morula rate (58.43 ± 7.98 and 36.14 ± 6.89, respectively) followed by TA. In conclusion, present study indicates that IVM, in vitro fertilization and in vitro culture of embryo are improved in the presence of TTL, particularly its TR section. Further study is expected to reveal the principal components of TTL which may prove useful for IVM.

Abstract
Purpose: To evaluate the role of image-guided fine-needle aspiration cytology (FNAC) of deep-seated lymph nodes. Material and Methods: Image-guided FNACs were performed on 242 patients of deep-seated lymph nodes which included thoracic, retroperitoneal and abdominal nodes. A sterile 3.5/5-MHz micro convex sector probe was used for localisation of the node. The FNAC was performed using a 0.7- to 0.9-mm needle with the stylet removed and attached to a 20-ml syringe and FNAC handle after the needle was visualised in the lesion. For each case a minimum of 4-5 smears were made, and two observers without bias interpreted the smears. Results: A total of 242 patients were aspirated, of which 216 (90%) aspirations were US-guided and the remaining 26 (10%) were CT-guided. Adequate material for cytologic diagnosis was obtained in 208 (86%) patients with a similar diagnostic accuracy. The aspirate material was non-representative or scanty in 34 (14%) patients. The most common cytological diagnosis was tuberculosis/consistent with tuberculosis seen in 108 (45%) patients followed by metastasis (17%) and reactive hyperplasia (10%). Non-Hodgkin lymphoma was diagnosed in 22 (9%) patients. All patients were briefly followed for a period of 1 1/2 to 2 years (mean 1 year). Conclusion: Image-guided FNAC has a pivotal role, and is a cost-effective tool for establishing tissue diagnosis as a primary investigative modality. It is also helpful and accurate in follow-up of patients with a known malignant disease, thereby avoiding surgical intervention.

Abstract
BACKGROUND Recently, a new population of IL-17-producing CD4 T helper (Th) cells, named Th17, was identified and shown to be involved in various inflammatory and autoimmune diseases, including psoriasis. AIM To determine the frequency of Th17 cells and related cytokines in peripheral blood of patients with psoriasis, and to analyse their association with disease severity. METHODS This was a prospective study comprising 34 patients with psoriasis and 24 healthy controls. Clinicoepidemiological details of patients were recorded, and severity of psoriasis was assessed by means of the Psoriasis Area and Severity Index. Circulating Th1 and Th17 cells in untreated patients with psoriasis and healthy controls were quantified by flow cytometry. In sera collected from patients with psoriasis and healthy controls, concentrations of IL-17A and IL-23 were examined by ELISA. RESULTS Increased frequencies of CD4+ IL-17A+ T cells were seen in peripheral blood of patients with psoriasis vulgaris (P < 0.001). Although serum IL-17A and IL-23 concentrations were higher in patients with psoriasis than in controls, the results did not reach statistical significance. We could not find any correlation between the studied T cells or related cytokines and the disease severity. CONCLUSION Increased serum levels of circulating Th17 cells and related cytokines may contribute to the cutaneous pathology of psoriasis, as well as the inflammatory process that is a hallmark of psoriasis.

Abstract
The ocular system can be affected in systemic lupus erythematosus (SLE) in one third of patients. However, optic nerve involvement is relatively uncommon, but is more so in pediatric SLE patients, where it can occur in 1% of cases. We report three children with SLE who presented with optic nerve involvement. Two children had optic neuritis, with optic neuritis being the first manifestation in one child. The third child had ischaemic optic neuropathy secondary to antiphospholipid syndrome. A careful work up for SLE should be performed in every child with optic nerve disease. Prompt diagnosis and early treatment results in a better prognosis.

Abstract
OBJECTIVE Data on outcome of childhood lupus nephritis from developing countries are sparse. This study looks at outcome in children with lupus nephritis from a federal government-funded teaching hospital in North India. METHODS This study included children less than 14 years of age with lupus nephritis who presented to a single center during a period of 24 years (1991 to 2013). Data on clinical characteristics and outcome were extracted from medical records. The primary outcome was actuarial survival (time-to-death) and secondary outcome was actuarial renal survival using Kaplan-Meier analysis. A worst-case scenario that assumed children who were lost to follow-up as having either died or gone into end-stage renal disease was also calculated. Log-rank test and Cox-regression were used to assess difference in survival by histological class and predictors of poor outcome, respectively. RESULTS This study included 72 children, with a female:male ratio of 3:1, mean (±SD) age at onset of lupus 9.3 (±2.4) years and mean (±SD) time from onset-to-nephritis being 9.4 (±12.6) months. Renal biopsy was conducted in 53 children. The most common histological class was class IV (35 children). Mortality occurred in 22 children (30%), with half of these occurring at presentation. The two important causes of death were infection and end-stage renal disease. Actuarial survival was 81%, 67% and 59% at one, five and 10 years, respectively. In the worst-case scenario, actuarial survival was 72%, 53% and 38%, respectively. Renal survival was 96%, 89% and 78% (worst-case scenario 86%, 73% and 52%) at one, five and 10 years, respectively. There was no difference in survival by histological class. On univariate analysis, serum creatinine at presentation (hazard ratio = 2.2 (95% CI 1.3-3.9)) and serious infection (hazard ratio 7.9 (95% CI 2.6-23.5)) were statistically significant predictors of time-to-death. CONCLUSION Outcome of children with lupus nephritis from India is worse than developed countries. Nearly one-third of the children died, half at presentation, with common causes being infection and end-stage renal disease.

Abstract
The present study was undertaken to evaluate the role of propofol in altering pentylenetetrazol induced seizure threshold in rats. Total 42 Wistar rats were used to evaluate different parameters (onset of action, duration of seizure, seizure severity score and number of seizure) following propofol injection. The present results showed that there was significant reduction in the time required for onset of seizure in propofol treated groups following PTZ treatment. If treated with propofol alone (2 and 5 mg/kg), there was no significant difference as compared to controls. In seizure severity score assessment, there was no significant difference with various doses of propofol alone treated groups, but the difference was observed in propofol (2 and 5 mg/kg) treated groups following PTZ treatment. Duration of seizure also significantly increased in propofol (5 mg/kg) treated group, but at 2 mg/kg of propofol treatment, no significant difference was observed. The present results showed that propofol ameliorate seizure threshold and caused prolongation of duration of seizure. However, further study and trials are needed to confirm the present results.

Abstract
OBJECTIVE To evaluate the role of fine needle aspiration biopsy (FNAB) material in 25 HIV-positive cases with lymphadenopathy. STUDY DESIGN We selected 25 cases for the present study who were enzyme-linked immunosorbent assay positive for HIV (HIV-1). FNAB was performed as a routine, outdoor procedure with informed consent of the patient. For each case, along with routine May-Grünwald-Giemsa and hematoxylin and eosin staining, Ziehl-Neelsen staining for acid-fast bacilli and periodic acid-Schiff staining for fungi were performed wherever necessary. RESULTS A total of 28 sites were aspirated from 25 HIV patients. All these patients were heterosexual, and none had a history of drug abuse. FNAB was performed under ultrasound guidance in all four cases of a retroperitoneal group of lymph nodes. The most common FNAB diagnosis was reactive lymphoid hyperplasia (10), followed by tuberculosis (8). There were three cases diagnosed as fungal infection (two, Cryptococcus; one, histoplasmosis). FNAB of a case of lymph node was suggestive of tuberculosis. There was one case each diagnosed as non-Hodgkin's lymphoma and squamous cell carcinoma (metastatic). One case of a small axillary lymph node did not yield representative material. CONCLUSION FNAB is a relatively inexpensive initial investigative technique in the diagnosis and management of HIV-positive patients. It can obviate the need for surgical excision and enable immediate treatment of specific infections.

Abstract
OBJECTIVE To analyze cases of palpable cutaneous/ subcutaneous scalp nodules and evaluate the clinical features and role of fine needle aspiration cytology (FNAC) in their diagnosis. STUDY DESIGN A total of 1,022 cases of metastatic malignancies at various sites were analyzed over a period of two years. FNAC was performed as a routine outpatient procedure for palpable lesions and under ultrasound or computed tomographic guidance for nonpalpable, internal sites. Histologic correlation was done when possible. RESULTS Eighteen cases were found to be metastatic scalp nodules. The scalp as a metastatic site constituted 1.76% of all metastatic sites, 7.72% of extranodal sites, and 15.3% of extranodal and extrahepatic sites. Of the 18 cases, 7 (38.9%) had primaries in the head and neck region (thyroid, 3; orbit, 1; tonsil, 1; tongue, 1; and parathyroid, 1). Cutaneous/subcutaneous metastasis was encountered in 58 patients, and the 18 cases of scalp metastasis constituted 31.03% of all cutaneous sites. CONCLUSION Careful examination of the skin on the entire body, with particular attention to the scalp, should be done when a primary internal malignancy or recurrence is suspected. FNAC is a very helpful and cost-effective modality in determining the nature of such lesions.

Abstract
A giant-cell tumor of the sacrum is rare, and poses significant therapeutic and surgical difficulties largely because of its location. Patients usually present with pain in the lower back radiating to one or both lower limbs, with or without neurological deficit. The index case presented with difficulty in defecation, in addition to pain in both lower limbs for 6 mo. The patient was seen to have a rectal mass, and a per-rectal fine-needle-aspiration was performed. The smears showed a cellular aspirate composed of a large number of osteoclastic giant cells, admixed intimately with clusters and a scattered population of mononuclear cells. Mitotic figures were not observed. Although the differential diagnosis of osteoclastic giant cell-containing lesions is broad, the presence of strong cohesiveness between the mononucleated cells and giant cells in cohesive clusters is a very helpful diagnostic feature, and was a prominent finding in the present case.
