Adrenal Ganglioneuroma.

Adrenal ganglioneuromas are rare sympathetic differentiated tumors which originate from neural crest cells. These lesions are usually discovered incidentally on imaging and tend to be hormonally silent. Preoperative diagnosis of adrenal ganglioneuroma remains extremely challenging and the gold standard treatment is adrenalectomy. There is good prognosis after surgery without recurrence. We herein report a case of adrenal ganglioneuroma in a 15 year old female who presented with complaint of abdominal discomfort. Contrast Enhanced Computed Tomography abdomen showed a large septated hypodense right suprarenal mass which was echogenic on Ultrasonography. It showed T1 hypointense and T2 hyperintense signal on Magnetic Resonance Imaging of abdomen and pelvis. Excisional biopsy and histological examination of the mass was suggestive of adrenal ganglioneuroma. This report presents the clinical and radiological data for the rare tumor which would share some experience to facililate the diagnosis of adrenal ganglioneuroma.

Post-Operative Pain and Associated Factors in Patients Undergoing Single Visit Root Canal Treatment on Teeth with Vital Pulp.

Background Pain after root canal therapy is unwanted yet common experience for the patient and unpleasant for the dentist so it is always desirable to predict such pain. Objective To evaluate the frequency, intensity and associated factors of post-operative pain after single visit endodontic therapy on teeth with vital pulps. Method A total of 418 single visit root canal treatments were performed on patients of age 18 years and above by two endodontists. Canals were shaped with rotary ProTaper files. After the canal preparation, the canals were obturated, using lateral compaction technique, with ProTaper universal gutta-percha and AH-Plus sealer. Independent factors were recorded during the treatment and characteristics of postoperative pain were later surveyed through questionnaires. The severity of pain was recorded on a visual analogue scale (VAS) of 0-5. The data were analyzed using logistic regression models. Result The prevalence of post-operative pain within first six hours after treatment was high (79.2%) which decreased to 22% at the end of 72 hours however majority (70%) of the patients had mild to moderate pain (VAS 1-2). The factors that significantly influenced post-obturation pain experience were: gender (OR=0.55, 95%CI=0.32- 0.93; p=0.03), tooth type (OR-0.67; 95% CI=10.56-0.81, p=0.00), history of preoperative pain (OR=1.26; 95% CI= 1.04-1.51; p=0.02) and number of canals (OR=2.03; 95% CI=1.40-2.95; p=0.00). Conclusion The prevalence of some level of post -operative pain after single visit root canal therapy was high and was significantly influenced by female gender, increased number of canals, posterior tooth type and positive history of pre-operative pain.

Effect of holding of semen and washing of seminal plasma on quality and fertility of Hampshire boar semen preserved at liquid state.

The present study was aimed to reveal the effect on keeping quality of boar semen on holding or not holding at an elevated temperature than that used for preservation when combined with washing or not washing of seminal plasma. Twenty ejaculates, four from each of five Hampshire boars were used to hold for 0 and 4h in GEPS extender at 22°C and subsequently washed (1500×g for 10min) of seminal plasma or left unwashed and preserved at 15°C for 72h after extending with the same extender. The seminal parameters in terms of sperm motility, live spermatozoa, and live spermatozoa with intact acrosome (LIA) were evaluated at 0h-(immediately after extension) and thereafter at 24h intervals. The mean percentage of sperm motility was significantly (P<0.01) higher in unwashed than washed semen at both 0h and 4h of holding irrespective of preservation period. It was significantly (P<0.01) higher in semen held for 4h than 0h irrespective of washing and significantly (P<0.01) lower in washed than in unwashed semen irrespective of holding during preservation. Irrespective of preservation period the mean percentage of live spermatozoa was significantly (P<0.01) higher with 4h than 0h of holding in both unwashed and washed semen and was significantly (P<0.01) higher in unwashed than washed semen at both 0h and 4h of holding. It was significantly (P<0.01) higher for 4h held semen irrespective of washing and was significantly (P<0.01) lower in washed than in unwashed semen irrespective of holding during preservation. The mean percentage of LIA was significantly (P<0.01) higher with 4h than with 0h holding in both unwashed and washed semen and was significantly (P<0.01) higher in unwashed than in washed semen at both 0h and 4h of holding irrespective of preservation period. It was significantly (P<0.01) higher for 4h held as compared to unheld semen irrespective of washing and was significantly (P<0.01) lower in washed than unwashed semen irrespective of holding during preservation. The mean percentage of sperm motility, live spermatozoa and LIA decreased significantly (P<0.01) in 0h and 4h holding irrespective of washing and in unwashed and washed semen irrespective of holding with increase in preservation period. Among all the treatments unwashed semen held for 4h yielded superior sperm quality on preservation. A total of 32 female pigs were inseminated using preserved semen obtained with the best processing technique found in the study. The conception rate, farrowing rate and litter size at birth were recorded to be 81.25%, 78.13% and 7.96 respectively as compared to 73.38%, 67.57% and 6.68 respectively in the control group. It could be concluded that unwashed Hampshire boar semen held for 4h, extended with GEPS and preserved at 15°C for 72h was conducive to obtain optimum fertility and fecundity in females when used for artificial insemination.

Physical and morphometric characterization of indigenous cattle of Assam.

The present investigation was undertaken to study the physical and morphometric characteristics in indigenous cattle of Assam. The data pertain to 339 indigenous cattle of different categories. The physical characteristics included colour pattern of body coat, muzzle, tail switch, hoof and horn. Body length, height at wither, heart girth, pouch girth, length of tail, switch, neck, ear and head were taken up for morphometric characterization. The main body coat colour of indigenous cattle was brown (31.18%) followed by white (28.53%), fawn (15.29%), grey (13.53%), black (4.41%) and mixed (7.06%). The prominent colour of tail switch was black (74.53%). Most of animals had black muzzle (86.47%), black hooves (84.71%) and black horn (100%). Morphometric characteristics data obtained were classified according to location, age group and sex of the animal. The means for body length, height at wither, heart girth, pouch girth, length of tail, switch, neck, ear and head were 83.668±0.590, 91.942±0.55, 113.146±0.738, 121.181±0.761, 54.196±0.527, 26.098±0.186, 32.705±0.166, 18.131±0.111 and 35.035±0.195 cm, respectively. Age and sex had significant effect on all the morphometric characters however, location effect was non-significant. The indigenous cattle of Assam are comparatively smaller in size than most of the recognized breeds of cattle however coat colour showed sizeable variation. The data generated for indigenous cattle of Assam would be useful to characterize them.
