Diagnostic Exercise from The Latin Comparative Pathology Group. Clinical History: A young adult, spayed female dog was presented for necropsy by animal control, with concerns for abuse in the form of chemical burns. Necropsy and Microscopic Findings: There was marked alopecia and coalescing ulceration affecting approximately 60% of the integument, roughly evenly distributed over the body. Affected areas included the mucocutaneous junctions, the palmar and plantar surfaces of the limbs, the paw pads, and the nasal planum. Ulcers measured up to 1 cm in diameter, frequently coalesced, and varied in stage of development; some were prominent, dark red, and shiny with roughened borders and others contained pink granulation tissue. In areas of alopecia without ulceration, the skin was smooth and glistening. The nails were variably sloughed; some digits possessed a bare quick and some had nails up to 3 cm long, but which were separating from the underlying quick. The dog was in adequate body condition.

Although chemical burns constitute 3% to 5% of all burns, they are responsible for 30% of burn-related deaths. Chemical burns cause protein denaturation in physiological proteins by different mechanisms such as reduction, oxidation, corrosion, purification, salinization, and protoplasmic poisoning. Time is very important in the treatment of chemical burns. Chemical substances should be removed very quickly from the body. Chemical scalp burns (with bones) are a rare injury in clinical practice. In the case of scalp burns, including bones, it becomes an important problem when flab surgeries fail or cannot be performed. This study was planned to examine the formation of granulation tissue by drilling holes in the cranium after chemical scalp burns, and to determine the process of grafting and clinical practice. A 55-year-old male patient was admitted to the emergency department after a chemical burn (nitric acid). He was admitted to the burn center with 20% of the total chemical burn being in the third degree, especially on the head and chest area. The patient was treated with debridement. Since the cranial periosteum was burned, the defect was wide and there was a chemical burn for the second time, graft and flap surgeries could not be performed. Multiple holes were drilled on the skull. Approximately a month later, granulation was observed in all holes in the cranium. The granulated areas in the skull were cleaned and debrided. The defect in the cranium was closed with a split thickness graft. Approximately 15 days later, he was discharged from the hospital. Therefore, after exposure to nitric acid, more than half of the scalp was burned to the bone. After the necrotic tissues were cleaned, the skull bones appeared. Since graft and flap surgeries could not be performed, granulation was stimulated on the cranium by opening holes in the skull.

Reproductive  health education should be given since early childhood by using language that is adapted to the stage of development. If you procrastinate and wait until the teenager it is already too late because in the days of the digital era, as now, all the information can be easily accessed by anyone including children early age. If the early childhood misinformed about their reproductive organs it would disrupt the physical and psychological development due to the wrong behavior in caring for and maintaining reproductive organs. Qur’an as the holy book of Muslims describes the steps of reproduction and  imparting education wisely as well as how to apply such education. This kind of education must be in accordance with the conditions of children and there should not be a lie about it We can also use media and methods such as pictures, songs, tap or other visual  media which can give clearer information, so that children can clearly see parts of the body, their characteristics, and how to treat and care them. The impropriate approach in conveying this kind of knowledge will be very dangerous for children. The provision of early age reproductive organs education can prevent the occurrence of deviant behavior as well as protect children from dangerous influence in early childhood development.

Abstract Background Phenotyping dementia is always a complex task for a clinician. There is a need for more practical biomarkers to aid clinicians. Objective The aim of the study is to investigate the shape profile of corpus callosum (CC) in different phenotypes of dementia. Materials and Methods Our study included patients who underwent neuroimaging in our facility as a part of clinical evaluation for dementia referred from Geriatric Clinic (2017–2018). We have analyzed the shape of CC and interpreted the finding using a seven-segment division. Results The sample included MPRAGE images of Alzheimer’ dementia (AD) (n = 24), posterior cortical atrophy- Alzheimer’ dementia (PCA-AD) (n = 7), behavioral variant of frontotemporal dementia (Bv-FTD) (n = 17), semantic variant frontotemporal dementia (Sv-FTD) (n = 11), progressive nonfluent aphasia (PNFA) (n = 4), Parkinson’s disease dementia (PDD) (n = 5), diffuse Lewy body dementia (n = 7), progressive supranuclear palsy (PSP) (n = 3), and corticobasal degeneration (CBD) (n = 3). We found in posterior dementias such as AD and PCA-AD that there was predominant atrophy of splenium of CC. In Bv-FTD, the genu and anterior half of the body of CC was atrophied, whereas in PNFA, PSP, PDD, and CBD there was atrophy of the body of CC giving a dumbbell like profile. Conclusion Our study findings were in agreement with the anatomical cortical regions involved in different phenotypes of dementia. Our preliminary study highlighted potential usefulness of CC in the clinical setting for phenotyping dementia in addition to clinical history and robust biomarkers.

The aim of the current study was to evaluate the relation of automatically determined body condition score (BCS) and inline biomarkers such as β-hydroxybutyrate (BHB), milk yield (MY), lactate dehydrogenase (LDH), and progesterone (mP4) with the pregnancy success of cows. The cows (n = 281) had 2.1 ± 0.1. lactations on average, were 151.6 ± 0.06 days postpartum, and were once tested with “Easy scan” ultrasound (IMV imaging, Scotland) at 30–35 d post-insemination. According to their reproductive status, cows were grouped into two groups: non-pregnant (n = 194 or 69.0% of cows) and pregnant (n = 87 or 31.0% of cows). Data concerning their BCS, mP4, MY, BHB, and LDH were collected each day from the day of insemination for 7 days. The BCS was collected with body condition score camera (DeLaval Inc., Tumba, Sweden); mP4, MY, BHB, and LDH were collected with the fully automated real-time analyzer Herd Navigator™ (Lattec I/S, Hillerød, Denmark) in combination with a DeLaval milking robot (DeLaval Inc., Tumba, Sweden). Of all the biomarkers, three differences between groups were significant. The body condition score (BCS) of the pregnant cows was higher (+0.49 score), the milk yield (MY) was lower (−4.36 kg), and milk progesterone in pregnant cows was (+6.11 ng/mL) higher compared to the group of non-pregnant cows (p < 0.001). The pregnancy status of the cows was associated with their BCS assessment (p < 0.001). We estimated that cows with BCS > 3.2 were 22 times more likely to have reproductive success than cows with BCS ≤ 3.2.

AbstractWe investigated effects of ecological and physiological factors on brood patch area and prolactin levels in free-ranging Lesser Snow Geese (Chen caerulescens caerulescens; hereafter “Snow Geese”) and Ross's Geese (C. rossii). On the basis of the body-size hypothesis, we predicted that the relationships between prolactin levels, brood patch area, and body condition would be stronger in Ross's Geese than in the larger Snow Geese. We found that brood patch area was positively related to clutch volume and inversely related to prolactin levels in Ross's Geese, but not in Snow Geese. Nest size, nest habitat, and first egg date did not affect brood patch area in either species. Prolactin levels increased as incubation progressed in female Snow Geese, but this relationship was not significant in Ross's Geese. Prolactin levels and body condition (as indexed by size-adjusted body mass) were inversely related in Ross's Geese, but not in Snow Geese. Our findings are consistent with the prediction that relationships between prolactin levels, brood patch area, and body condition are relatively stronger in Ross's Geese, because they mobilize endogenous reserves at faster rates than Snow Geese.Factores Ecológicos y Fisiológicos que Afectan el Área del Parche de Incubación y los Niveles de Prolactina en Gansos Nidificantes del Ártico

The insectivorous bat Myotis nigricans is widely distributed throughout the Neotropics, including Brazil, and has a reproductive biology that is affected by climate and food availability. To evaluate the reproductive capacity of this species, morphofunctional parameters of the testes were correlated with environmental variables and the body condition of individuals captured. After bats had been killed, their testes were removed, fixed in Karnovsky’s fluid for 24 h and embedded in resin for evaluation by light microscopy. The mean annual tubulosomatic index (0.58%) and the percentage of seminiferous tubules in the testes (88.96%) were the highest ever recorded for the Order Chiroptera. The percentage of Leydig cells and volume of the cytoplasm of Leydig cells were higher in the rainy than dry season (80.62 ± 3.19% and 573.57 ± 166.95 μm, respectively; mean ± s.d.). Conversely, the percentage of nuclei of the Leydig cells in the dry season (26.17 ± 3.70%; mean ± s.d.) and the total number of Leydig cells (6.38 ± 1.84 × 109; mean ± s.d.) were higher in the dry season. The results of the present study could help in future conservation of these bats because they provide a better understanding of the bats’ reproductive strategies and how the species can adapt to changes.

Abstract BACKGROUND Pediatric and Young-Adult (AYA) brain tumors often present with hydrocephalus. As temporary cerebrospinal fluid (CSF) diversion procedure, we perform long-term indwelling external ventricular drainage (EVD) in the case of the management of CSF diversion more than two weeks presumably. The aim of this study is to investigate the initial management for hydrocephalus in pediatric /AYA patients with brain tumor, especially about long-term EVD. MATERIALS AND METHODS The patients less than 30 years of age diagnosed with brain tumor between 2005 and 2019 were retrospectively analyzed. Procedures of long-term EVD were similar to that of ventriculoperitoneal shunt (VPS) operation. Using flow-control VPS system, peritoneal catheter passed out of the body at the anterior chest, and distal end of the catheter was connected to standard EVD system. RESULTS In total of 345 patients with brain tumor, 109 had hydrocephalus at presentation. Among them, 25 patients (23%) underwent long-term EVD. The main reasons for selecting long-term EVD were to avoid intraperitoneal dissemination (n=13), and to maintain longer period of CSF diversion for the treatment of tumor (n=12). The median of long-term EVD was 38 days (range: 12 – 222 days). Although one case suffered from drainage tube occlusion at 59 days, there were no other complications such as infection or accidental evulsion. Eventually, 3 cases required permanent VPS for persistent hydrocephalus. CONCLUSION Long-term EVD is safe and effective option for CSF diversion. This procedure should be taken into consideration if patients have a risk of dissemination and may elude permanent VPS.

AbstractChanges in the body condition of Antarctic minke whales (Balaenoptera bonaerensis) have been investigated in a number of studies, but remain contested. Here we provide a new analysis of body condition measurements, with particularly careful attention to the statistical model building and to model selection issues. We analyse body condition data for a large number (4704) of minke whales caught between 1987 and 2005. The data consist of five different variables related to body condition (fat weight, blubber thickness and girth) and a number of temporal, spatial and biological covariates. The body condition variables are analysed using linear mixed-effects models, for which we provide sound biological motivation. Further, we conduct model selection with the focused information criterion (FIC), reflecting the fact that we have a clearly specified research question, which leads us to a clear focus parameter of particular interest. We find that there has been a substantial decline in body condition over the study period (the net declines are estimated to 10% for fat weight, 7% for blubber thickness and 3% for the girth). Interestingly, there seems to be some differences in body condition trends between males and females and in different regions of the Antarctic. The decline in body condition could indicate major changes in the Antarctic ecosystem, in particular, increased competition from some larger krill-eating whale species.

Полноценное, сбалансированное питание - основной фактор в формировании здоровья детей, когда в организме наиболее интенсивно протекают процессы роста и развития, формируются и созревают многие органы и системы, совершенствуются их функции. В статье приведены основные направления исследований зарубежных и отечественных ученых по лечению генетических заболеваний, таких как фенилкетонурия. Одним из приоритетных направлений в области здорового питания населения России в соответствии со Стратегией научно-технологического развития РФ до 2030 г. является развитие производства пищевых продуктов, обогащенных незаменимыми ингредиентами, специализированных продуктов детского питания, продуктов функционального назначения, диетических пищевых продуктов и биологически активных добавок. По данным ВОЗ от структуры питания на 70 % зависят здоровье и физическое развитие детей и подростков. Фенилкетонурия (ФКУ) - наследственное заболевание, вызывающее нарушение метаболизма аминокислоты фенилаланина у ребенка, одно из первых, рекомендованных ВОЗ для ранней диагностики у новорожденных. Отсутствие лечения вызывают серьезное поражение центральной нервной системы, отставание в умственном и физическом развитии. Особенностью современного этапа развития диетотерапии для детей, страдающих различными заболеваниями, в том числе наследственными, является разработка качественных функциональных продуктов питания, способствующих сохранению и улучшению здоровья ребенка за счет регулирующего и нормализующего воздействия на организм с учетом его физиологического состояния и возраста. Данные продукты можно широко использовать в практике лечебного питания не только в составе гипофенилаланиновой диеты, но и при любых заболеваниях, требующих ее соблюдения. В настоящее время единственным методом лечения ФКУ является диетотерапия, организованная с первых дней жизни с использованием специализированных смесей без фенилаланина. Из питания исключаются высокобелковые продукты растительного и животного происхождения. Целью лечебного воздействия диеты на ребенка является поддержка концентрации фенилаланина (ФА) в крови в пределах 2-12 мг на 100 мл в зависимости от возраста ребенка. Full-fledged balanced nutrition is the main factor in the formation of children's health, when the processes of growth and development are most intense in the body, many organs and systems are formed and mature, and their functions are improved. The article presents the main research areas of foreign and domestic scientists on the treatment of genetic diseases, such as phenylketonuria. One of the priority areas in the field of healthy nutrition of the Russian population in accordance with the Strategy for Scientific and Technological Development of the Russian Federation until 2030 is the development of the production of food products enriched with essential ingredients, specialized children's food products, functional products, dietary food products and biologically active additives. According to WHO, the health and physical development of children and adolescents depends on the nutritional structure by 70%. Phenylketonuria (PKN) - an inherited disease that causes impaired metabolism of the amino acid phenylalanine in a child - is one of the first recommended by WHO for early diagnosis in newborns. Lack of treatment causes serious damage to the central nervous system, a lag in mental and physical development. A feature of the modern stage of development of dietary therapy for children suffering from various diseases, including hereditary ones, is the development of quality functional food products that contribute to the preservation and improvement of the health of the child, due to the regulatory and normalizing effect on the body, taking into account its physiological state and age. These products can be widely used in the practice of therapeutic nutrition not only in the sastava of the hypophenylalanine diet, but also for any diseases requiring its observance. Currently, the only method of treating PKN is diet therapy, organized from the first days of life using specialized mixtures without phenylalanine. High-protein products of vegetable and animal origin are excluded from nutrition. The goal of the therapeutic effect of the diet on the child is to maintain the concentration of phenylalanine (FA) in the blood in the range of 2-12 mg per 100 ml, depending on the age of the child.
