Background: Performing identity is a prime task in medicolegal and postmortem examinations. Age is the first parameter that has to be determined followed by sex. There are several techniques through which sex can be determined. As well there are different anatomical, physiological and pathological parameters determination of sex. Aim: To determine the sexual dimorphism in the cranial sagittal suture closure macroscopically. Methods: All the cases for this purpose had been selected from those brought for autopsy in the Department of Forensic Medicine and Toxicology, King Edward Medical University Lahore during the year 2016. Results: The statistical analysis revealed early closure in males than in females both ectocranially and endocranially with advancing age in the sagittal suture of cranial vault. The p value was found significant being less than 0.05 thereby establishing the fact that sexual dimorphism in the cranial sagittal suture exists. Conclusion: Conclusively the determination of sex is possible from the pattern of Cranial Sutures closure on autopsy table. Key words: Sex, Sagittal, Suture, Cranial

A total of 65 skulls of the Australian sealion, Neophoca cinerea, was examined to investigate the extent to which sexual dimorphism is reflected in cranial dimensions (n = 32) and skull growth, and to determine whether cranial sutures (n = 18) can be useful in age determination. All adult skull dimensions studied display significant sexual dimorphism. Skull growth ceases close to 4–7 years of age for females (Suture Fusion Rating, SFR 25–34) but skull growth in males continues until at least 16 years of age. In animals with a SFR ≥� 25, male skulls have a minimum condylobasal length of 272 mm, whereas female skulls have a maximum condylobasal length of 259 mm. The relatively early closure of the cranial vault sutures (cessation of brain growth) is balanced by the continued growth of the bony projections that provide muscle attachment (e.g. mastoid width). The later fusion of the snout and palate sutures corresponds with the continued growth of the snout and palate to match the prolonged growth of the mandibles. The upper sixth postcanine tooth was present in 43% of the adult female skulls, but only 15% of the adult male skulls. The data suggest that it may be possible to determine age(s) from examination of the sequence of fusion of cranial sutures as well as by calculation of an overall suture fusion rating for the skull.

Suture Closure

Background:- Age estimation is one of the important parameters for estimation of biological profile of an individual. Generally speaking, estimation of age of an individual whether living or dead is very important in Medicolegal and forensic scenario. The objective of the present study was to observe the chronology and pattern of union of cranial sutures namely coronal and lambdoid and to find out the relationship between closure of cranial suture and age of the deceased. An attempt was also made to see the applicability of Acsadi and Nemeskeri method in an Indian population. A total of 193 adult calvaria (133 males and 60 females) were studied from the autopsy cases. The extent of obliteration was studied ectocranially and endocranially in the two main sutures of the calvarium i.e. coronal and lambdoid. Results:- The results indicate that a strong positive correlation of ectocranial with endocranial suture closure is found in the age group of 30-39 years for right coronal, left coronal, while age group of 60-69 years shows a strong positive correlation for lambdoid sutures. This has also been confirmed in the study that the cranial suture obliteration starts endocranially and proceeds towards ectocranial surface. Statistically insignificant sex differences exist in suture closure. Conclusion:- The coronal and lambdoid sutures were closed in the age group of above 70 years with mean values of 3.54 for coronal and 3.7 for lambdoid suture. Acsadi and Nemeskeri’s method was found to be applicable to the Indian population for determination of age from cranial sutures.

Early Surgical Treatment

One hundred and twenty children have been treated surgically for premature fusion of the cranial sutures in this clinic. Thirty-six of these have been operated on in the first six months of life and constitute the material on which this report is based. These have included 19 instances of sagittal suture closure, 10 of coronal closure, 5 of multiple suture involvement and 2 miscellaneous cases. The marked reduction in incidence and degree of mental retardation, the prevention of visual impairment, and the improvement in cosmetic appearance which can be achieved by recognition and surgical treatment of this lesion in early infancy are emphasized. The operation of choice in this clinic is linear craniectomy parallel to the suture which is prematurely fused with insertion of polyethylene film over the bony margins to delay closure. With proper precautions and supportive treatment this type of surgery is well tolerated and the complications are negligible during the first few months of life.

The banana agro-export sector in Ecuador provides millions of dollars in income for this concept, but with this development, a series of quality standards have been established that must be met to enter the export system. This has contributed to establishing good post-harvest production and management practices that guarantee the optimal production of bananas and plantains. The objective of this study was to determine the factors involved in the rejection of bananas (Musa acuminata) destined for international commercialization. The methodology considered the design modality of non-experimental transactional research, with a quantitative approach. The methodological design was developed in three phases at Finca 6 Hermanas located in the Barraganete sector of the San Juan parish in the Puebloviejo canton of the Los Ríos Province, Ecuador. The results highlight that the main causes for which banana rejection is generated are due to abiotic factors (damage, dry latex, scar, insect damage, broken neck, overgrowth) in a higher percentage of 79.55 % and biotic factors ( twins, diseases, short finger) by 20.45 %. The average rejection was 6 361 fingers and1 269 Kilograms (K) over the 6-week study duration. The analysis of variance turned out to be significant for variable 1 (biotic and abiotic). Ho is rejected; with the criterion of p-value < 0.0001 and F (9; 45) = 2.10., F = 13.17> F critic. In the case of variable (2) “work weeks”, Ho is accepted with the criteria obtained of p-value of 0.7694 and F (5; 45) = 2.4., As F = 0.51 < F critic, it is concludes, that with a significance level of 5% the null hypothesis is accepted. It is concluded that these figures lead to the elaboration of strategies that systemically mitigate the damages, by correcting each one of the causes that cause the deterioration of the banana and increasing the economic gains of the commercialization process.

Abstract Background Sex determination is one of the leading criterion in identification and verification of an individual. However, the potential roles of differences in adjacent fingerprint white line count (FWLC) in sex inference are not well elucidated in the literature especially among Hausa population. The study was conducted to determine sexual dimorphism and predict sex using adjacent digit FWLC difference (adj. DFWLCD) among Hausa population of Kano state, Nigeria. Methods The study population involved 300 participants. FWLC was determined from a plain fingerprint captured using live scanner. The formula for adj. DFWLCD of thumb and fifth digit is dR15 for right hand. The same applied for possible combination in cephalocaudal direction. Mann-Whitney and t tests were used for comparison of variables between sexes. Binary logistic regression analyses were employed for determination of sex. Results We observed a significantly larger adj. DFWLCD in males compared with females in most of the digit combination. A significant sexual dimorphism was observed in most of the adj. DFWLCD involving ring digit in both right (dR14, dR24, and dR34) and left (dL14, dL24, and dL34). The best discrimination was observed in adjacent FWLC difference of second and fourth digits in both right and left digits (dR24 and dL24). This was further supported by stepwise logistic regression analyses. Conclusion The adj. DFWLCD exhibits sexual dimorphism. The best prediction potentials were found to be dR24 and dL24 for right and left hands respectively.

Symptomatic Intracranial Hemorrhage

Background and Purpose: Time to reperfusion is an essential factor in determination of outcomes in (AIS). We sought to establish the effect of the procedural time on the clinical and radiographic outcomes of AIS patients undergoing intra-arterial therapy. Methods: Retrospective review of a prospectively collected database of endovascularly treated large vessel AIS in a large academic center. Data from all consecutive patients who underwent mechanical thrombectomy from September 2010 to July 2012 were analyzed. The variable of interest was procedural time (defined as time from groin puncture to end of procedure). Outcome measures included the rates of symptomatic intracebral hemorrhage (sICH, defined as any parenchymal hematoma e.g. PH-1/PH-2), final infarct volume, 90-day mortality, and independent functional outcomes (modified Rankin Scale, mRS 0-2) at 90 days. Results: The entire cohort included 242 patients with a mean age of 65.5+/- 14.2 and median baseline NIHSS 20. Of the patients 49.38% were females. The median ASPECTS score was 8. The mean procedure time was significantly shorter in patients with good outcome (86.73 vs. 73.13 respectively, P-value: 0.0228). However, after controlling for ASPECTS score, type of retrieval device, TICI score, volume of infarct, interval from symptoms onset to puncture, and co-morbidities, this association did not prove to be significant (P-value = 0.7101). Patients with SICH had significantly higher mean procedure time than patients without SICH (79.65 vs. 104.5 respectively; P-value: 0.0319) which remained significant when controlling to the previous factors (OR = 0.974 with a 95 % CI of (0.957, 0.991). There was no correlation between the volume of infarction and the procedure time (r = 0.10996, P-value: 0.0984). There was no association between procedure time and 90-day mortality (77.8 vs. 88.2 minutes in survivals vs. deaths respectively; P-value: 0.0958). Conclusion: Our data support an association between the risk of SICH and a longer procedure time while no definite association between procedural times and the final infarction volume or long-term functional outcomes was found after adjustment for multiple imbalances.

The Relationship

No matter how simple, at first glance, the old method of determining the position of the fetal head in the pelvic cavity along the sagittal suture and fontanelles, it still sometimes leads to unpleasant mistakes not only for inexperienced, novice doctors, but sometimes for doctors with quite a long local experience, and even , albeit more rarely, specialist doctors. Difficulties in such a determination of the position of the head in the pelvis arise especially when this accuracy is especially needed, that is, during obstetric operations (the imposition of forceps, perforator, cranioclast, etc.). In these cases, either due to the long standing of the head, or due to its inconsistency with the mother's pelvis, both the sagittal suture and the fontanelles are very strongly masked by the head tumor and the configuration of the head. Even a very experienced obstetrician-gynecologist can hardly understand the resulting picture of the relationship between sutures and fontanelles.

Background: Various factors have been identified as influencing factors of breast cancer. The free radicals can cause increased oxidative stress by negatively affecting the body’s nucleic acids, lipids and proteins leading to various illnesses including cancer. Therefore, this study was aimed at discovering the progress of treatment of breast carcinoma by exploring the connections of the disease with free radical injury.Methods: The present study was conducted among 30 breast carcinoma patients received in the surgery department of BRD Medical College Gorakhpur. Determination of the levels superoxide dismutase (SOD) (the procedure of photoluminescence), catalase (method of Cavarochi) and the lipid peroxidise was done. The results were presented as mean and standard error (SE). P value of <0.05 was considered as statistically significant.Results: Among the total participants, 73% patients had infiltrating ductal carcinoma and 27% patients had intraductal carcinoma. The dismutase levels showed an increase in the post-operative patients for both the groups. The catalase levels and the lipid peroxide levels showed a reduction in the postoperative patients (p<0.05).Conclusions: The present study result showed that the low amounts of SOD and catalase may not be sufficient to detoxify high amounts of free radicals. The administration of catalase could help in reducing the symptoms. Though, low amounts of SOD and catalase may not be sufficient to detoxify high amounts of free radicals. The administration of enzymes could help in the treatment of breast cancer patients.
