Vascular variations of the head and neck are common, but oft en go unnoticed because they generally do not present clear clinical symptoms. Lack of awareness of the presence and location of such variations may result in iatrogenic complications or even fatalities. Physicians and surgeons should be cognizant of such variations given their potential clinical signifi cance.

Pressure head was gained from the distribution of pores to characterize the sandstones of the Shajara reservoirs of the permo-Carboniferous Shajara Formation. The attained values of pressure head were employed to calculate the pressure head fractal dimension. Based on field observations in addition to the acquired values of the pressure head fractal dimension, the sandstones of Shajara reservoirs were divided here into three units. The obtained units from base to top are: Lower Shajara Pressure Head Fractal Dimension Unit, Middle Shajara Pressure Head Fractal Dimension Unit and Upper Shajara Pressure Head Fractal Dimension Unit.

Patients under two years of age who were admitted Emergency Department (ED) within three months due to MHT and who underwent cranial CT scan were included in the study. Trauma mechanisms, Glasgow Coma Scale (GCS) scores, symptoms (crying/unrest, vomiting, to refuse eating, drowsiness, loss of consciousness) and clinical signs (hyperemia/ecchymosis, abrasion, skin laceration, cephalohematoma, fontanel bulging) were retrospectively screened.

A sixty-five-years-old male patient with history of non-Hodgkin’s lymphoma of the right orbit and a fifty-years-old female patient with chronic lymphocytic leukemia with peripheral lymphocytosis were treated on TomoTherapy. In the first case, a 1 cm beam was used for planning a delivery of 30.6 Gy in 17 fractions with a sequential boost of 9 Gy in 5 fractions. Tumor involvement of the ipsilateral lens and lacrimal gland in the planning target volume necessitated a compromise between preserving patient’s vision and delivery of tumoricidal dose to the target. In the second case, 30 Gy in 20 fractions delivery was planned with a 2.5 cm beam. The tumor extended anteriorly and this technique allowed sparing more orbital tissue and required a high modulation factor.

Medical records of each occurrence of neurologic signs in 181 South American Camelids admitted on 185 occasions (90 alpacas and 95 llamas) were evaluated. Age ranged from 0 days to 20 years, but 70.5% of cases were ≥ 1 year old. Specific clinical diagnosis was achieved by cerebrospinal fluid analysis (CSF), radiographs, computed tomography, laboratory testing, or necropsy in 74% of cases. 54% of cases survived; 46% of cases died or were euthanized. The most common diagnosis (31%) was parasitic myelopathy/encephalopathy (PME). CSF eosinophilia ≥10% was found in 85% of parasitic spinal migrations but only in 55% of intracranial migrations, and 73% had increased protein in CSF. There was a seasonal bias for PME with 79% of cases occurring between October and March. Survival of PME cases was 77% for spinal migration but only 7% when intracranial migration occurred. The most common diagnoses, excluding PME, were infectious disease (15%) and trauma (12%). Most trauma cases involved the cervical spine of which 50% survived.

A cross- sectional study was conducted to assess the nutritional status of the children with rickets aged <5 years at District Headquarter Hospital, Upper Dir in which 50 children were included 33 (66%) male and 17 (34%) female. The study included anthropometric measurement (weight, height and head circumference), clinical presentation, radiographic findings, biochemical assessments, dietary status and information about exposure to sun. clinical results reveal that all children were having one or more clinical signs and symptoms of nutritional rickets including rachitic rosary (14%), widely open anterior fontanel (22%), widening of wrist (14%), bowing of legs (14%), chest infection (22%), diarrhea (10%), delayed eruption of teeth (24%), failure to thrive (10%), fits (4%), sweating (26%) and irritability (20%).

Headache is among the main pediatric symptom and the physicians should meet the diagnostic criteria of the International Headache Society. In a cross-sectional study, during August 2015 to August 2016, the types of headaches and the sociodemographic profile of patients between 4 and 18 years of age were evaluated. The headache patients were previously diagnosed and followed at the Pediatric Neurology Service of Salvador, according to established criteria. The study was approved by Research Ethics Committee and it was carried out with the application of a specific questionnaire. In the overall study population (N = 58) were detected: primary headache migraine type that incapacitated the daily activities in 34/58 (58.6%) and the socioeconomic profile showed the family income below two salaries (in Real currency) in 38/58 (65.5%) of the population. As observed in adults, the headaches constitute a disabling diagnosis and it is impactful in the development of activities of daily living in the age group of this study, corroborating the literature on the importance of early diagnosis and therapy.

Two replicate studies were conducted on a commercial goat dairy. The objective was to determine the effects of dietary supplementation with OmniGen-AF, a nutritional supplement that supports immune function in ruminants, on milk production, somatic cell count (SCC), percentages milk fat (%MF) and milk protein (%MP) in lactating dairy goats.

The posterior approach to the hip joint involves operating in close proximity to the sciatic nerve. Iatrogenic injury to the sciatic nerve has been reported to occur in 0.6 - 1.9% of cases [1]. Stretching, transection or suturing of the nerve may occur during access or while closing the capsule and short external rotators to the hip.

Mutation in a single nucleotide of a gene has the potential to change the structure and/or function of its protein. Albeit simply saying, it is not observed to be a general phenomenon. The effect of mutation is primarily determined by the stereochemical nature of the amino acid which has replaced the previous amino acid, resulting in the residue location being affected. Here we show that despite a change in the frequency of occurrence of a particular amino acid in a particular protein in different types of organisms, the overall function of the protein can still remain unaffected, even when the resultant protein conformation is relatively altered.
