This document summarizes a study that examined dermatoglyphic patterns (fingerprints and handprints) in autistic children in Nigeria. The researchers took fingerprints and palm prints from 20 autistic children and 20 non-autistic children. They analyzed and compared the digital patterns, ridge counts, and other dermatoglyphic features between the two groups. Some differences were observed between the autistic and non-autistic groups, such as differences in the frequency of arch, whorl, ulnar loop, and radial loop patterns. However, no statistically significant differences were found when comparing total ridge counts and a-b ridge counts between the groups. The study aims to determine if there are any correlations between dermatoglyph
Cephalofacial indices of the ibo and yoruba ethnic groups in southern nigeriaAlexander Decker
The document summarizes a study that measured cephalic and facial indices of Ibo and Yoruba ethnic groups in southern Nigeria. The study found that Ibo subjects had higher cephalic indices than Yoruba subjects, with both groups falling in the brachycephalic head type range. Facial indices showed both groups had a hypereuriprosopic face type. Cephalic index showed sexual dimorphism only in the Yoruba group. The data provides information on head and face shapes of the ethnic groups that can be useful for forensic and medical purposes.
Idiopathic scoliosis is a spinal deformity that affects otherwise healthy children and adolescents during growth. Genetic factors are known to play a role based on twin studies. While over 35 candidate genes have been identified, the genetic variants that affect susceptibility to spinal curvature and progression remain unknown. Estrogen receptors have been extensively examined as candidates due to their role in bone growth, but studies on the association between idiopathic scoliosis and estrogen receptor genes like ESR1 and ESR2 have had inconsistent results. More research is needed to better understand the genetic basis and identify individuals at risk of progression to help improve treatment options.
This document summarizes a study that aims to determine which combinations of clinical signs observed on prenatal ultrasounds best predict a mutation in genes COL1A1 or COL1A2 that causes Osteogenesis imperfecta (OI), a genetic disorder that causes brittle bones. The study analyzes data collected from prenatal cases submitted to a collagen diagnostic lab, including ultrasound findings of signs like shortened long bones, bowed bones, and fractures, as well as the results of genetic testing. The goal is to establish guidelines for physicians to help recognize OI in fetuses and determine when genetic testing is required, in order to provide better care for affected fetuses and families.
Enhancing Rare Disease Literature for Researchers and PatientsErin D. Foster
This document discusses efforts to enhance accessibility of rare disease literature for researchers and patients. It describes adding layperson synonyms to the Human Phenotype Ontology to help patients understand disease descriptions. Over 44% of existing synonyms were marked as layperson terms. The document also discusses a pilot project to annotate rare disease case reports with associated genes and phenotypes to identify the rarest cases and facilitate information sharing and community building. Next steps include further literature annotation and incorporating the data into databases. The overall goal is to improve dissemination of information on rare diseases.
1. The document analyzes clinical signs seen on ultrasounds of fetuses suspected of having Osteogenesis Imperfecta (OI) and whether those signs correlate with mutations found in type 1 collagen genes (COL1A1 and COL1A2) after genetic testing.
2. Data from 31 fetuses showed that 53% had mutations in type 1 collagen genes confirming OI. 100% of those cases showed bowed long bones and multiple fractures on ultrasound.
3. The results suggest that fractures and bowed long bones are the most common clinical signs seen on ultrasound in fetuses later diagnosed with OI through genetic testing.
The document discusses research being conducted by Oregon scientists on the sexual preferences of male sheep. The research aims to study biological factors associated with sexual orientation in sheep. However, the research has generated significant backlash from animal rights and LGBT groups who have misinterpreted the goals of the research. Media coverage of the research has spread misinformation and accusations against the scientists. The scientists emphasize that their research goal is to further basic scientific understanding and not to change human sexuality.

The document summarizes a study on the clinical and socio-demographic profile of patients with dissociative disorder. Key findings include:
1) Dissociative disorder was more prevalent among females (75%) between the ages of 30-40 years, who were married housewives with low socioeconomic status and education.
2) The most common presentations were trance and possession (30%) and motor dissociation (25%).
3) Most patients were from rural areas (62.25%) and of lower socioeconomic status (65%), highlighting dissociative disorder is more common in developing countries.
Hearing loss among elderly patients in an ear clinic in nigeriaAlexander Decker
This study investigated hearing loss patterns among elderly patients seen at an ear clinic in Nigeria. Of the 586 patients who underwent audiometry over 3 years, 88 (15%) were elderly (age 65+). The mean age was 72.4 years and most were males. Over 80% had hearing loss, and 82% of those had disabling hearing loss. While sensorineural hearing loss was most common, mixed and conductive hearing losses were also present. Moderately severe hearing loss was the most prevalent. The majority had a sloping audiometric pattern typical of presbycusis, but other patterns occurred as well. Disabling hearing loss is very common in the elderly and often goes unaddressed, risking social
This study examined 79 dry crania (55 male and 24 female) from southern Nigeria to determine the incidence and dimensions of single and double hypoglossal canals, and whether these dimensions differ between sexes. Measurements were taken of the internal and external diameters of the hypoglossal canals. The results showed significant differences in all dimensions between males and females. Bilateral single hypoglossal canals were most prevalent. In conclusion, the size of the hypoglossal canal is sex-specific, with significant differences found between males and females in this population.

This study examined the incidence of absence of the palmaris longus tendon in 1,020 subjects from Jordan. The overall absence was 38.62%, with bilateral absence being more common than unilateral absence. Absence was more common in females compared to males. While bilateral absence was higher in left-handed subjects, the differences were not statistically significant. The findings add to variability reported in literature and show the middle eastern population has a higher prevalence of absence than Caucasian populations.
This study aimed to determine the prevalence of knee osteoarthritis (OA) in India through a community-based cross-sectional study of 5,000 subjects across five regions of India. The overall prevalence of knee OA was found to be 28.7%, with higher rates in females, older individuals, those with higher BMI, sedentary lifestyles, and those who used western toilets. Risk factors associated with knee OA included age, gender, BMI, physical activity level, occupation, and lifestyle. The results were consistent with prior studies showing knee OA is common and prevalence increases with age, especially in females over 45 years old.

Analytical Study of Clinicopathological Data of Saudi Patients with Osteoarth...Prof. Hesham N. Mustafa
SUMMARY: Knee osteoarthritis (OA) is a common disabling disease. Epidemiological studies have revealed various risk
factors for OA, including sex, aging, obesity, occupational illnesses, and chronic diseases. Here we evaluate the clinical, pathological,
and radiological findings of knee OA in a subset of Saudi patients who were subjected to total knee replacement (TKA). The study
population included 30 Saudi patients with knee OA who were operated by TKA (from June 2014 to December 2015) in the Department
of Orthopedics, Faculty of Medicine, King Abdulaziz University, Saudi Arabia. Patient’s clinical and radiological data were collected
from the hospital files. Pathological examination of the excised superior articular surface of tibia and femoral condyles were done.
Pearson Chi-squared analysis was used to test for differences between the variables in associated risk factors. There were more women
than men. Sixty per cent of patients were older than 60 years [mean age, 59.2 (females) and 61.7 (men) years-old]. All patients exceeded
obesity class 1, with females being more obese than males. Pathological examination of the superior articular surface of tibia and femoral
condyles showed high score lesions, which was more apparent in females than in males. Radiological findings showed that most lesions
were high grade. The findings of this study will help to understand the pathogenesis of OA and improve treatment decision making
relevant to TKA in knee OA in Saudi Arabia and elsewhere.

Women with polycystic ovary syndrome (PCOS) have elevated levels of hormones like luteinizing hormone and testosterone, as well as higher levels of insulin and insulin resistance compared to healthy women. They also have increased levels of inflammatory markers like C-reactive protein, interleukin-6, and leptin. This study found these abnormalities in the hormones and inflammatory cytokines of women with PCOS ages 23-40, indicating that hormone imbalances associated with insulin resistance and elevated inflammatory markers may worsen infertility in women with PCOS.

A universal model for managing the marketing executives in nigerian banksAlexander Decker
This document discusses a study that aimed to synthesize motivation theories into a universal model for managing marketing executives in Nigerian banks. The study was guided by Maslow and McGregor's theories. A sample of 303 marketing executives was used. The results showed that managers will be most effective at motivating marketing executives if they consider individual needs and create challenging but attainable goals. The emerged model suggests managers should provide job satisfaction by tailoring assignments to abilities and monitoring performance with feedback. This addresses confusion faced by Nigerian bank managers in determining effective motivation strategies.

This document summarizes a study on the determinants of savings in Namibia from 1991 to 2012. It reviews previous literature on savings determinants in developing countries. The study uses time series analysis including unit root tests, cointegration, and error correction models to analyze the relationship between savings and variables like income, inflation, population growth, deposit rates, and financial deepening in Namibia. The results found inflation and income have a positive impact on savings, while population growth negatively impacts savings. Deposit rates and financial deepening were found to have no significant impact. The study reinforces previous work and emphasizes the importance of improving income levels to achieve higher savings rates in Namibia.

A survey paper on sequence pattern mining with incrementalAlexander Decker
This document summarizes four algorithms for sequential pattern mining: GSP, ISM, FreeSpan, and PrefixSpan. GSP is an Apriori-based algorithm that incorporates time constraints. ISM extends SPADE to incrementally update patterns after database changes. FreeSpan uses frequent items to recursively project databases and grow subsequences. PrefixSpan also uses projection but claims to not require candidate generation. It recursively projects databases based on short prefix patterns. The document concludes by stating the goal was to find an efficient scheme for extracting sequential patterns from transactional datasets.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties.

ABSTRACT
Dermatoglyphic patterns have positive correlation in a number of genetic diseases. This research was carried out
to determine any possible relationship between dermatoglyphics and autism in Nigeria using digital and palmar
patterns, total ridge count, a-b ridge count and crease pattern. The digital and palmar prints of 20 autistic subjects
from an autistic centre in Port Harcourt, Rivers state Nigeria were taken with parental guidance. The percentage
frequency distribution of the digital pattern of the autistic subject was 49.5% for the arch, 18.5% for the whorl,
28.5% for the ulnar loop and 3.5% for the radial loop against 44% for the ulnar loop, 25.5% for the arch, 22% for
the whorl and 8.5% for the radial loop for normal subjects. The mean values of the a –b ridge counts on the right
and left hands of autistic male were 34.66 and 33.33 against 36.40 and 31.33 in non-autistic children
respectively while in female they were 38.6 and 35.8 against 41.40 and 38.6 respectively.
Though no statistical significant difference was observed when the two groups were compared (P>0.05). It was,
however, observed that the number of the total ridge counts in the right and left hands of the autistic children
were lower than those of the normal subjects. Thus, there is need for further investigation using larger sample
size. The data from this study will serve as a good reference for future study on this subject in Nigeria.
Key Words: Dermatoglyphics and Autism
INTRODUCTION
Autism is a complex developmental disorder or disability that typically appears during the first three years of
life.The term autism was derived from a Greek word “Auto” meaning self, thus it is also defined as the tendency
to morbid self absorption at the expense of regulation by outward reality. Autism impairs the normal
development of the brain in the area of social interaction and communication skills. Children and adult with
autism typically have difficulties in verbal and non-verbal communication, social interactions, and leisure.
Autism is the most common of the pervasive Developmental Disorders, affecting an estimated 2 – 6 per 1,000 or
0.002 – 0.006% individuals, this means that as many as 300,000 to 900, 000 Nigerians today are believed to have
some form of autism. It is four times more prevalent in boys than girls. Autism is mutifactorial, that is it is
influenced by both genetic and environmental factors (Walker, 2005).
Studies have shown that a positive correlation exist between dermatoglyphics and some disease conditions,
especially those with genetic basis. Such conditions include those associated with organic mental
retardation(Boroffice,1978;Steveson et al.,1997;Than et al.,1998;Franceschini et al.,2002).It has been suggested
also that dermatoglyhic studies may aid in the diagnosis of such conditions(Rex and Preus,1982;Schmnidt et
al.,1981).Nervous system disorders of functional ethiopathogenesis have also been positively correlated with
dermatoglyphics. These include schizophrenia(Oladipo et al.,2005) and schizotypal personality(Van-Os et
al.,2000).Reports are also available on the correlation of Dermatoglyphics in Diabetes mellitus(Oladipo and
Ogunowo,2004), Idiopathic(primary) dilated cardiomyopathy(Oladipo et al.,2007) , breast cancer(Oladipo et
al.,2009), epileptic disorder (Bogdanov et al., 1999), rheumatism(Belov and Miakotkin, 1988) prostate cancer
(Oladipo et al.,2009;Howard et al., 1988 ).
This study was carried out to determine any possible correlation between dermatoglyphic patterns and autism in
Nigeria.

MATERIALS AND METHODS
In this study, 20 autistic (16 males and 4 females) and 20 non autistic (16 males and 4 females) children were
selected from the Autistic Centre and the Catholic Special Child Day School in Port Harcourt Rivers State,
Nigeria. All subjects were Nigerians by both parents and grandparents.
The parents/guidance of the children were administered a questionnaire containing their names, age, sex
background and behaviour to fill to make sure they fall into the category.
Fingerprints were then taken with white paper and purple ink pad (Penrose,1963). Hands were thoroughly
washed with water and soap and dried before taking prints. This was done to remove dirt from the hands.
Screening was done on the white duplicating paper containing the prints with the aid of a magnifying glass. No
distinction was made between the varieties of whorl (w) patterns, also tented arch was recorded as an arch
(A).Loop was recorded as either ulnar loop (UL) or radial loop (RL).All the patterns were as defined by Penrose
(1963).A straight line was drawn to join A and B triradii and the number of intersecting ridges counted. These
gave A-B ridge counts(Figure 1).
The various digits were designated as follow: Thumb- i; Index finger-ii; Middle finger-iii; Ring finger-iv; Little
finger-v. L and R stand for left and right respectively.
Data analysis: The student t-test and chi-square test were used for statistical analysis at significant level of 0.05.

RESULTS
The mean percentage frequency distribution of digital pattern among autistic and normal subjects (left hand) is
summarized in table 1.Arch and Radial loop had the highest number in autistic patient compare to normal
subjects. While the Whorl and Ulnar loop showed the highest percentage frequency in normal subject compare to
autistic patients.
The mean percentage frequency distribution of digital pattern among autistic and normal subjects (right hand) is
summarized in table 2. Arch and Ulnar loop had the highest frequency in autistic patient compare to normal
subjects. While the Whorl and Radial loop showed the highest percentage frequency in normal subject compare
to autistic patients.
The total ridge counts on each digit of autistic patients is summarized in table 3,the total ridge count is higher on
the left hand compared to the right hand, although within the highest count on the thumb of the right hand.
The total ridge counts on each digit of normal subjects is summarized in table 4,In normal subjects the total

ridge count is also higher on the left hand as compare to the right, but the overall total count is about twice
higher in normal subject compare to autistic patients
The mean, standard deviation and standard error of A-B ridge count of both normal and autistic male and female
subject is summarized in tables 5 and 6.A-B ridge counts is observed to by higher in both normal and autistic
females than male, but no significant difference was observed statistically.
DISCUSSION
Dermatoglyphic analysis of the digital patterns in Down’s syndrome and normal individuals showed a
statistically significant different of 96% loop pattern as against 63.6% in normal (Boroffice, 1978). No such
difference was observed in the present study.
On the right palm arch and ulnar loop had the highest frequency in autistic patient compare to normal subjects.
While the Whorl and Radial loop showed the highest percentage frequency in normal subject compare to autistic
patients, on the left palm arch and radial loop had the highest number in autistic patient compare to normal
subjects. While the Whorl and Ulnar loop showed the highest percentage frequency in normal subject compare to
autistic patients.
In this study it was observed that the total ridge count of both right and left hands of the normal subjects were
higher compare to those of autistic patients, our findings is in line with that of Walker, 2005,who compared the
dermatoglyphic patterns of autistic children to control subjects matched socioeconomically and by age and sex.
Analysis of the dermal ridge patterns and ridge count resulted in significant difference between the 78 autistic
and 78 normal children.
CONCLUSION
It is recommended that this study should be carried out in other centres in Nigeria to establish standard parameter
values which could be used when making diagnosis for these patients.
