Background: The prostate may become larger and begin to cause problems as male ages. Ultrasound is a commonly used imaging modality for the assessment of the prostate. Objective: The aim of this study was to identify the normal measurements (volume and diameters) of the prostate gland in Khartoum state Sudan in normal Sudanese. Method: This descriptive study of the study was done in Sudan teaching hospital, from March –to October 2019. 60 patients were randomly selected, their age ranged from 20 to 60 years; patients with symptoms related to prostate pathologies were excluded. Transabdominal ultrasound scanning by3.5 MHz probes was performed. And the Maximum length, width, and depth of the prostate diameters were obtained as well as the prostate volumes. Results: The results of the study revealed that the prostate length, width and thickness Diameters mean values were (4.88) cm, (3.37) cm, and (4.55) cm respectively, the Mean prostate volume obtained from the above parameters was18.65 ml. The study also showed that there was an increase in the prostate volume in relation to an increase in the patient's age and weight. Transabdominal ultrasound is a respectful approach and should be used confident pathologies among Sudanese and for normal measurements.

The physical and engineering properties of fresh and dried tiger nut (Cyperus esculentus) were determined at moisture content of 41.20% and 16.40% on wet basis respectively. The mean values for the three principal axes (length, width and thickness) were 9.52mm, 8.16mm, and 8.16mm for fresh tiger nut and 9.14mm, 7.72mm and 8.03mm for dried tiger nut respectively, showing a decrease with decrease in moisture content and was significantly different at p?0.05. The mean values of the bulk density, true density and porosity of both fresh and dried tiger nut were 0.59g/cm3 , 0.97g/cm3 , 40.61 and 0.58g/cm3, 0.94g/cm3 , 40.35 respectively and were not significantly different at p?0.05. The mean angle of repose and coefficient of static friction over formica, stainless steel, glass and plywood surfaces of fresh tiger nut were 50.11o , 2.73, 2.45, 2.22 and 1.77 while that of dried tiger nut were 48.23o , 2.41, 2.03, 2.11 and 2.00 respectively. The mean rupture force increased with compression force of 90.08N on the major axis to 116.88N for fresh tiger nut and from 120.55N to 161.10N for dried tiger nut and were significantly different at p?0.05. These properties determined are necessary in the design and fabrication of hoppers, conveyor equipment and the force tiger nut can withstand before it is ruptured.

The Impact

138 Background: PSA density (PSAD) is a strong predictor of aggressive prostate cancer (PCa) and is often used as a selection criterion for active surveillance. However, measurement of PSAD can vary depending on the modality used to estimate prostate volume (PV). We analyzed a prospective cohort of men undergoing MRI−US fusion biopsy to assess the variation in PV obtained with both imaging modalities, and investigate the impact of this variation on PSAD measurement in order to determine if it led to re-classification of patients above or below the current threshold of PSAD used in clinical practice (0.15 ng/mL/cc). Methods: All men were consecutively enrolled in this prospective study and had their PV measured on MRI prior to prostate biopsy (PB), and on Trans-Rectal Ultrasound (TRUS) at the time of PB. PSAD was calculated by dividing the last PSA prior to biopsy by the PV ascertained with each imaging modality. We used paired t-tests and Wilcoxon signed−rank tests to compare the difference in PV and PSAD obtained with TRUS and MRI. We also categorized PSAD measurements on each imaging modality above and below a cut-off of 0.15 ng/mL/cc. We used the McNemar’s test for paired proportions to estimate the significance of discordance in PSAD categorization based on each imaging modality. Results: Of the 124 men, the mean PV assessed with MRI (70 cc) was 7 cc more on average (SD: 11, median = 4 cc) than that obtained with TRUS (63 cc) (P < 0.0001). Furthermore, the mean PSAD obtained with MRI (0.17 ng/mL/cc), was 0.01 ng/mL/cc lower (SD: 0.07, median = 0.01) than that obtained with TRUS (0.18 ng/mL/cc) (P < 0.0001). 118 (95%) men had concordant PSAD values assessed with either imaging modality using the cut-off of 0.15 ng/mL/cc. All 6 (5%) men with discordant PSAD values who were above the cut-off with PV obtained via TRUS were reclassified as being below the cut-off with PV assessed via MRI (P < 0.01). Conclusions: MRI can overestimate PV compared to TRUS. This may translate to reclassification of men around the currently used PSAD threshold and have implications for treatment decision making and selection of patients for active surveillance.

There is a lack of accurate three-dimensional studies to locate malar prominence for specified population, this study aims to locate the malar prominence using stable landmarks using CBCT. To derive a novel method to accurately locate the malar prominence and to assess and compare the malar prominence between males and females among Bangalore population using 3D CBCT study. All CBCT scans of study subjects belong to Bangalore population were collected from the pre-existing data available in Radiology imaging Solutions (CBCT centre), Bangalore during the period of September 10th to October 10th 2020. This is a descriptive study. A total of 42 subjects including 21 Males and 21 females were assessed using full skull CBCT scans which were converted to DICOM format and reconstructed into 3D images using NEMOCEPH 3D software. Landmarks used to locate the malar prominence were Fzs, Z, Zm and Ans. The intersection of these landmarks is considered to be as constructed maxillozygion(My). For the accuracy of the constructed Maxillozygion point (My), the distance between the actual Maxillozygion (Mzy) and constructed Maxillozygion (My) is measured and calculated between left and right halves of males and females. Three Orthogonal planes constructed were Midsagittal, Axial and Coronal Planes and the linear measurements with reference to all three reference planes in both the groups are measured. Student paired t- Test, Independent Student t Test, Mann Whitney Test. The mean distance from Mzy and my between right and left half of the face was compared using student paired t- Test. There is no significant difference (p=0.35).The mean values of the constructed anatomical landmark (maxillozygion) coordinated to three orthogonal planes between right and left sides of the face is compared using student paired T test and for both the genders (males and females) was compared using Independent Student t Test, and it is significantly higher in males as compared to females and it is statistically significant at (p=0.01). The location of malar prominence using CBCT by a novel method for Bangalore population is found which can be helpful in diagnosis and treatment planning for malar augmentation, camouflage treatment in subjects with midface deficiencies.

The study was undertaken on 11 Surti male kids of identical age and birth weight from 14 weeks of age till puberty and sexual maturity up to 47 weeks (12 months) of age. The scrotal biometry, i.e., length, width, circumference (cm) and volume (cm3) were recorded using standard procedures at 3 weeks intervals. The mean weight of animals at birth, 14 and 35 weeks of age was 1.53±0.05, 9.86±0.61 kg and 17.84±1.09 kg, respectively and thereafter it did not change much till 47 weeks of age. Similarly, the mean values of scrotal length, width, circumference (cm) and scrotal volume (cm3) at 14 weeks of age were 2.89±0.22, 2.05±0.17, 8.82±0.72 and 21.36±0.93, respectively, which then gradually increased with an advancing age till 35 weeks of age reaching 10.65±0.30, 7.55±0.24, 19.45±0.65 and 200.45±16.67, respectively, which later became almost stable. At puberty, the average age and body weight were 27.00±0.75 weeks and 15.16±0.56 kg, and at sexual maturity 38.18±0.90 weeks and 19.61±0.93 kg, respectively. Great individual variation was noted in all the biometric traits among bucks studied. The blood plasma profile studied at bimonthly intervals revealed significant increase in total protein and ALT, and decrease in cholesterol and cobalt concentrations with advancing age. However, the AST and macro-micro minerals did not vary, suggestive of acquiring adult profile by 6 months of age. Based on the age, scrotal biometry, semen quality and blood biochemistry, it could be inferred that the Surti bucks attained full reproductive potential at around 9- 10 months of age with stable blood plasma profile.

Anthropologic parameters of the spleen are important because many diseases present with reduction or enlargement of the spleen. No data exists about the standard dimensions of the normal spleen in Iranian population. Therefore, the objective of the study was to investigate anthropologic parameters of the spleen in Iranian cadavers.  In 2014-2015, this cross sectional study was undertaken from the Razavi Khorasan Province of Iran. Iranian cadavers (n=693, 152 female/541 male) with no history of poisoning, drug or alcohol addiction, no gross abnormality and injury of the spleen were included in the study. The length, width and thickness of spleen were measured using a Vernier caliper. The mean values of the demographic data were age= 40.28 ± 20.97 years; weight = 63.68 ± 17.40 kg; height = 160.03 ± 28.45 cm and BMI = 25.03 ± 20.46 kg/m2. The mean values of the spleen length, width, thickness, notch, weight and index in the cadavers were 11.32 ± 3.10 cm, 8.05 ± 2.35 cm, 20.12 ± 9.21 mm, 0.84 ± 1.35, 123.87 ± 82.46 g, and 2.01 ± 1.40, respectively. Accessory spleen was found in five cadavers. The anthropologic parameters of the spleen showed significant difference between males and females except for index of the spleen.  Having standard data on the spleen is useful for radiologists, surgeons, anatomists and anthropologists. The results of the study may provide valuable data in the standardization of the anthropologic parameters of the spleen in the Iranian population.

The present study was conducted to determine the histological and histomorphometric variations in the tongue, oesophagus, proventriculus, and gizzard of ostriches (Struthio camelus) with regards to the sex and advancing age. A total of 40 healthy ostriches of both sexes and five age groups; young (up to 1 year, 1 to 2 years and 2 to 3 years) and adult (3 to 4 years and above 4 years) in equal numbers (n = 8) were used in this study. The organs under study were collected immediately after slaughtering the birds. Overall, the colour, shape, weight and various dimensions (length, width, and diameter) of the collected organs were recorded. The mean values of the gross anatomical variables of the studied organs increased (P &lt; 0.05) among all the young groups (i.e., from 1 to 2 years, 2 to 3 years). Similarly, the organs under study in the adult groups (birds aged 3 to 4 years and above 4 years) grew (P &lt; 0.05) as well. However, the differences between the adults were not significant. The histological analysis and histometric measurements were conducted on paraffin embedded tissue sections with Image J<sup>®</sup> analysis software. The statistical analysis revealed a significant increase in the thickness of the different tunics of the digestive organs in all the groups except those the adult groups. These findings may be of importance for the strategic manipulation of feed and nutrition to enhance the growth rate and also to diagnose pathological processes.

Introduction: Benign prostatic Hyperplasia is a common disorder and cause of morbidity in the ageing men. The evaluation symptoms and the bother associated with it are important for management. International Prostate Symptom Score (IPSS), Quality of life (QOL) and Benign Prostatic Hyperplasia Impact Index (BII) are practiced to quantify the severity of the disease. The size of prostate gland does not correlate with lower urinary tract symptoms. Correlation among above scoring is also not clear. Aim of the study is to evaluate correlation of prostate volume with International Prostate Symptom Score, Benign Prostatic Hyperplasia Impact Index and prostate size.Methods: Prospective study. Ninety-eight patients were included. Patients were assessed preoperatively with the International Prostate Symptom Score, Benign Prostatic Hyperplasia Impact Index and prostate volumes by trans abdominal ultrasound.Results: The mean age was 66.7  ± 7.3 years (50- 84) the mean IPSS, QOL, BII and prostate volumes were 23.6 ±6.0, 5.1 ± 0.9, 7.1±2.4 and 47.5±16.63 respectively. There was positive correlation between the IPSS and BII, IPSS and QOL and BII and  QOL (rs= 0.89, 0.585 and 0.530 respectively) and no correlation between IPSS and BII with prostatic weight. (rs= -0.04 and -0.07 respectively).Conclusion: Management of the benign prostate hyperplasia should be considered on the bother symptoms and not on the size of the prostate.Journal of Society of Surgeons of Nepal Vol.17(1) 2014: 6-10

The purpose of this study was to evaluate the correlation between real-time intra-operative ultrasound-based dosimetry (USD) and day 0 post-implant CT dosimetry (CTD) 131 Cs permanent prostate brachytherapy. Fifty-two consecutive patients who underwent prostate brachytherapy with 131 Cs were evaluated. Real time operating room planning was performed using VariSeed 7.1 software. Post-needle placement prostate volume was used for real-time planning. Targets for dosimetry were D90 >110%, V100 >90%, V150 <50%, and V200 <20%. The CT scan for post-operative dosimetry was obtained on day 0. The mean values for USD, CTD, and the linear correlation, respectively, were, for D90: 114.0%, 105.61%, and 0.15; for V100: 95.1%, 91.6%, and 0.22; for V150: 51.5%, 46.4%, and 0.40; and for V200: 15.8%, 17.9%, and 0.42. The differences between the mean values for USD and CTD for D90 (p<0.01), V100 (p<0.01), and V150 (p<0.05) were statistically significant. For D90, 30.8% of patients had a >15% difference between USD and CTD and 51.9% of patients had a >10% difference between these values. In contrast, the USD and CTD for V100 were within 5% in 55.8% of patients and within 10% in 86.5% of patients. This study demonstrates a correlation between the mean intra-operative USD and post-implant day 0 CTD values only for V200. Significant variation in D90, V150, and V200 values existed for individual patients between USD and CTD. These results suggest that real-time intra-operative USD does not serve as a surrogate for post-operative CTD, and that post-operative CTD is still necessary.
