Objective of the research: to study the features of the radiological picture of the brain and internal organs of newborns with severe perinatal asphyxia, who underwent general therapeutic hypothermia (GTH). Materials and methods: the study included 116 newborns with severe perinatal asphyxia. GTH was performed in 72 patients (group 1), 44 children did not receive hypothermia in the 2 (control) group. In the first 6 hours of life, children of groups 1 and 2 underwent ultrasound of the brain and abdominal organs and chest x-ray. The complex ultrasound scan was repeated at 3–5, 7–10, 14–16 and 21–28 days. Repeated chest x-ray was carried out strictly according to the indications. Results: GTH reduced the incidence of organic brain lesions by 18% in children with severe perinatal asphyxia (p0,05). The study revealed a number of undesirable consequences associated with GTH. Transient effusion into the abdominal and thoracic cavities was diagnosed by ultrasound in 8 (11%) patients after hypothermia, while there were no such changes in children in the control group (p<0,05). X-ray of the chest in newborns who received GTH during the first 14 days revealed edematous-hemorrhagic changes in the lungs more often than in patients of the control group – 55 (76%) and 24 (55%), respectively (p<0,05). Conclusions: GTH effectively prevented the development of severe post-hypoxic changes in the brain. The negative effect of hypothermia on microcirculation was manifested by the development of effusion into the serous cavities and edematous-hemorrhagic syndrome.

Purpose: Learning the state of the internal organs in newborns with severe perinatal asphyxia after general therapeutic hypothermia. Material and methods: 80 newborns with severe perinatal asphyxia born from January 2014 to May 2019 in Kursk were under observation. In the first 6 hours of life, 52 patients were started with general therapeutic hypothermia (1st observation group), 28 newborns did not perform hypothermia (2nd control group). All children underwent a dynamic complex radiological examination, included ultrasound of the brain, abdominal organs and retroperitoneal space, echocardiography with Doppler, chest X-rays. Results and discussion: In both groups of observations, radiation symptoms of liver and gallbladder changes were identified: a uniform increase in the echogenicity of the hepatic parenchyma (98.1 % of cases in group 1 and 100 % of cases in group 2, p > 0.05), visual “impoverishment” of the vascular pattern (98.1 % and 100 %, p > 0.05), hepatomegaly (19.2 % and 21.4 %, p > 0.05), thickening of the gallbladder walls, loose sediment or suspension in its lumen (7.7 % and 10.7 %, p > 0.05). All 80 examined patients showed a bilateral increase in echogenicity of the renal parenchyma with visual impoverishment of intraorgan blood flow and impaired corticomedullary differentiation. The described internal organs changes were reversible and due, in our opinion, mainly to the effect of asphyxiation and resuscitation measures. According to the results of chest X-ray, we did not reveal the effect of therapeutic hypothermia on the incidence of hospital pneumonia: it was found in 34.6 % newborns from the 1st group and in 42.9 % – from the 2nd one (p > 0.05). However, in the first 14 days of life the respiratory failure caused by edematous and hemorrhagic changes in patient’s lungs was detected more often in patients from observation group then in patients from control group: respectively 76.9 % and 42.8 % of cases (p <0.05). This indicates a negative effect of general therapeutic hypothermia on the respiratory system of newborns with severe perinatal asphyxia.

Abstract Background: Hypocalcemia, hypomagnesemia, and hyperphosphatemia are common electrolyte disturbances in perinatal asphyxia(PA). Different reasons have been proposed for these electrolyte disturbances. This study investigated the effect of the urinary excretion of calcium(Ca), magnesium(Mg), and phosphorus(P) on the serum levels of these substances in babies who were treated using therapeutic hypothermia for hypoxic ischemic encephalopathy(HİE) caused by PA. This study sheds light on the pathophysiology that may cause changes in the serum values of these electrolytes.Method: This study included 21 healthy newborns(control group) and 38 patients(HİE group) who had undergone therapeutic hypothermia due to HİE. Only infants with a gestational age of 36 weeks and above and a birth weight of 2000 g and above were evaluated. The urine and serum Ca, Mg, P, and creatinine levels of all infants were evaluated at 24, 48, and 72 hours.Results: The lower serum Ca value and the higher serum P value of the HİE group were found to be statistically significant compared to the control group. There was no significant difference in serum Mg values between the groups. However, hypomagnesemia was detected in five patients from the HİE group. The urine excretions of these substances, which were checked at different times, were found to be significantly higher in the HİE group compared to the control group.Conclusion: This study determined that the urinary excretion of Ca, Mg, and P has an effect on the serum Ca, Mg, and P levels of infants with HİE.

AbstractNo consensus exists regarding the definition of ventilator-associated pneumonia (VAP) in neonates and reliability of chest X-ray (CXR) is low. Lung ultrasound (LU) is a potential alternative diagnostic tool. The aim was to define characteristics of VAP in our patient population and propose a multiparameter score, incorporating LU, for VAP diagnosis. Between March 25, 2018, and May 25, 2019, infants with VAP were identified. Clinical, laboratory and microbiology data were collected. CXRs and LU scans were reviewed. A multiparameter VAP score, including LU, was calculated on Day 1 and Day 3 for infants with VAP and for a control group and compared with CXR. VAP incidence was 10.47 episodes/1000 ventilator days. LU and CXR were available for 31 episodes in 21 infants with VAP, and for six episodes in five patients without VAP. On Day 1, a VAP score of > 4, and on Day 3 a score of > 5 showed sensitivity of 0.94, and area under the curve of 0.91 and 0.97, respectively. AUC for clinical information only was 0.88 and for clinical and CXR 0.85.Conclusion: The multiparameter VAP score including LU could be useful in diagnosing VAP in neonates with underlying lung pathology. What is Known:• Ventilator associated pneumonia (VAP) is common in infants on the neonatal unit and is associated with increased use of antibiotics, prolonged ventilation and higher incidence of chronic lung disease.• Commonly used definitions of VAP are difficult to apply in neonates and interpretation of chest X-ray is challenging with poor inter-rater agreement in patients with underlying chronic lung disease. What is New:• The multiparameter VAP score combining clinical, microbiology and lung ultrasound (LU) data is predictive for VAP diagnosis in preterm infants with chronic lung disease.• LU findings of VAP in neonates showed high inter-rater agreement and included consolidated lung areas, dynamic bronchograms and pleural effusion.

Our objective was to estimate the effect of therapeutic hypothermia on platelet count in neonates after perinatal asphyxia. We performed a retrospective case control study of all (near-) term neonates with perinatal asphyxia admitted between 2004 and 2012 to our neonatal intensive care unit. All neonates treated with therapeutic hypothermia were included in this study (hypothermia group) and compared with a historic control group of neonates with perinatal asphyxia treated before introduction of therapeutic hypothermia (2008). Primary outcome was thrombocytopenia during the first week after birth. Thrombocytopenia was found significantly more often in the hypothermia group than in the control group, 80% (43/54) versus 59% (27/46) (P=.02). The lowest mean platelet count in the hypothermia group and control group was97×109/Land125×109/L(P=.06), respectively, and was reached at a mean age of 4.1 days in the hypothermia group and 2.9 days in the control group (P<.001). The incidence of moderate/severe cerebral hemorrhage was 6% (3/47) in the hypothermia group versus 9% (3/35) in the control group (P=.64). In conclusion, neonates with perinatal asphyxia treated with therapeutic hypothermia are at increased risk of thrombocytopenia, without increased risk of cerebral hemorrhage.

Study Results

The work is dedicated to the research of direct results and immediate possible complications of interventions in X-ray surgery with coronary stent implantation. Our patients with chronic coronary syndrome and reduced left ventricular ejection fraction (LVEF) of less than 40% were studied. The study included 112 patients who were divided into two groups. The first group included 51 patients with LVEF <40% (mean value 32.8 ± 1.14%), the second group involved 61 patients with LVEF >40% (mean value 59.4 ± 1.02%). The mean age of the subjects ranged from 59 to 74 years (mean value 63.85 ± 1.73 years). There were no gender-related differences among the selected patients. There was no statistical difference in comorbidities in both groups. Both groups of patients were examined and managed according to the protocol of diagnosis and treatment adopted at the National Amosov Institute of Cardiovascular Surgery for patients suffering from chronic coronary syndrome. The study results show that patients with coronary artery disease and reduced LVEF 2 times more often developed complications in early postoperative period after PCI with revascularization through stent placement than in group of patients with preserved contractile myocardial function. Duration of PCI procedure and contrast agent use was 26.3±1.4% and 29.8±4.2% higher, respectively; the frequency of life-threatening arrhythmias was 54% higher. Intraoperational signs of acute heart failure developed 4.8 times less often in the control group than in the experimental group. In general, all the patients after stenting achieved good anti-ischemic effect.

Background: The burden of interstitial lung disease (ILD) in rheumatoid arthritis (RA) patients in resource limited countries like India is often under-reported. This study was conducted to find out the clinicoradiological profile of ILD in patients with RA in India. Aims and Objectives: (1)To find out the frequency of Interstitial Lung Disease (ILD) in Rheumatoid Arthritis (RA) (2) To correlate the clinical findings with those of radiological(Chest x-ray & HRCT Thorax) and pulmonary function tests including Spirometry, TLCO (Diffusing capacity of the Lung for Carbon monoxide/DLCO Corrected for alveolar volume i.e., DLCO/V) Estimation. Materials and Methods: Thirty consecutive patients of RA (with or without pulmonary symptoms or signs) who fulfill the American Classification of Rheumatology criteria1987 were selected from the patients attending the General Medicine OPD (Rheumatology Division) of B.R. Singh Hospital during the study period regardless of being on any medications for RA. This was a cross-sectional, descriptive study. Results were tabulated in Microsoft office excel worksheet and descriptive statistics were expressed as means, standard deviations (SD) mean for continuous normally distributed data and as percentages. Statistical software SPSS version 19.0 was used for data analysis. Unpaired t test (for continuous data)/Chi square test (for proportion) was used for comparing cases and controls. Results: The frequency of ILD in RA was 60%. Female patients with a positive rheumatoid factor had a greater chance of development of ILD.The frequency was found to be increased after the age of 40 years. Though in this study 60% of patients had restrictive pattern, 31% had obstructive and 3 % had mixed pattern on Spirometry. The patients with deforming RA had greater frequency of restrictive or mixed pattern on Spirometry. 22.22% patients had a decreased TLCO despite having normal CXR. Despite being asymptomatic12 patients had restrictive lung disease and reduced TLCO with HRCT evidence of ILD. Overall, Spirometry & TLCO are the most appropriate tests to detect restrictive lung disease in patients with RA. In fact, HRCT can show evidence of ILD even when clinical parameters and Chest X-ray are normal.On HRCT of thorax reticular pattern and sub-pleural fibrosis (UIP-Usual interstitial pneumonia) are the predominant pattern. Conclusion: The frequency of ILD in RA is quite high. It may be recommended to use Spirometry & TLCO as screening test for detection of restrictive lung disease in patients with RA who should undergo HRCT of chest to confirm presence of ILD in a resource limited setting.

The aim: To define the degree for glial acidic fibrillary protein expression on the structural components of cerebellum of the rats in health and when rats influenced by the food additives complex. Materials and methods: In order to determine the degree of expression of the immunohistochemical marker GFAP on the structural components of the cerebellum of rats we applied immunohistochemical, morphometric and statistical methods in our study. Results: In histological specimens at the end of 1st week of observation in the gray matter of the cerebellum there occurred a gradual increase in 1.16 times of the average number of GFAP-positive cells. At the end of 4th week of the experimental study, the average number of GFAP-positive cells increased accurately (at p<0.05 compared to the control group) in 1.27 times, at the end of 8th week it has increased in 1.99 times, at the end of 12th week in 2.25, and at the end of 16th week in 2.39 times. Conclusions: The outcomes of our study are as follows the increase in the average number of GFAP-positive cells is directly related to the decrease in the average number of major neurons of the gray matter of the brain, while the fluctuations in the average number of astrocytic glia cells represent a compensatory mechanism in the recovery of gray matter neurons of the brain from neural stem cells with the subsequent development of reactive astrogliosis and, thereafter the possible development of neuropathology.

Abstract A patient who had a primary lung carcinoma in remission but had a solitary metastatic lesion to the cerebellum was referred to the neurosurgery service. He was noted to be thrombocytopenic, and further hemostatic evaluation revealed chronic disseminated intravascular coagulation. He was treated with heparin and platelet transfusions. Although the fibrinogen levels improved, the thrombocytopenia persisted. Four weeks after admission, repeat chest x-ray films and tomograms indicated progressing metastatic nodules. A review of the literature reveals a variety of hemostatic defects associated with tumor metastatic to the brain. This current case indicates the need for careful hemostatic evaluation in all patients with brain lesions.

This study investigated the neurohistological effect of lead acetate on cerebellar cortex of adult wistar rats. Lead is a common industrial poisonous substance that its prevalence in the environment exhibits toxic effect which makes different organs & tissues especially the central nervous system vulnerable to lead exposure. Lead is however, found useful applications in diverse items of daily needs like paints, water pipes, car batteries, leaded gasoline, ammunition, cosmetics, hair dye, airplanes, shielding for x-ray machines. Thirty-six (36) adult wistar rats of both sexes weighing between 120-250 grams were randomly grouped into four groups. Group A, B, C and D each group containing seven (9) rats. Group A rats served as the control, and was maintained on standard feed and water for 28 days, group B, C and D rats were treated orally once daily with 0.09g/kg, 0.18g/kg and 0.2g/kg of lead acetate respectively for 28 days. The weights of the wistar rats were recorded on weekly basis during the treatment. All the wistar rats in group A, B, C and D were sacrificed by cervical dislocation on the 29th day of the treatment. The brain was removed and weighed with a sensitive balance and the cerebellum of each rats was then fixed in 10% formol saline, the tissue was processed and stained with Hematoxylin and Eosin for histological study. Results showed that the mean body weights of the wistar rats significantly decreased in the treated groups when compared with the control group. The mean brain weights of the lead treated groups showed a significant decrease when compared to the control group. Histological study of the brain (cerebellar cortex) of the treated groups demonstrated degenerative changes revealed shrinkage, reduced sized and cellular loss of the Purkinje cells with vacuolations in the Purkinje cell layer compared with normal cerebellar histoarchitecture in the control. The study concluded that lead acetate has a neurotoxic effect on the cerebellar cortex of adult wistar rats which may ultimately impair some cerebellar functions.
