Ovarian cystadenocarcinoma with an osteosarcoma component, is a very rare tumor. We aimed to describe a case of an osteosarcoma arising in an ovarian squamous cell carcinoma.

This paper presents the dynamic model ofthe soliton. Based on this model, it is supposed to study the state of the network. The term neural networks refers to the networks of neurons in the mammalian brain. Neurons are its main units of computation. In the brain, they are connected together in a network to process data. This can be a very complex task, and so the dynamics of neural networks in the mammalian brain in response to external stimuli can be quite complex. The inputs and outputs of each neuron change as a function of time, in the form of so-called spike chains, but the network itself also changes. We learn and improve our data processing capabilities by establishing reconnections between neurons.

Aim of the study: Clarification for the time of the clinical improvement after management COVID-19 pneumonia versus normal gradation of common workup is the target for the current study. Background: COVID-19 pneumonia is a current serious international pandemic infection. Generally, in medical diseases, the clinical response is commonly parallel to laboratory and radiological improvement. This rule may be different in COVID-19 pneumonia. Method of study and patients: The author reported retrospective-observational 47-case report series. The study was conducted in a physician outpatient clinic thorough nearly 12-months, starting from Jun 9, 2020, and, ended on May 8, 2021. All included cases were COVID-19 pneumonia and treated with conventional antibiotics, anticoagulants, and steroids. Results: The mean ±SD age was: 50.08 (14.9) years, with male sex predominance (55.32%). The mean days of clinical versus leukocytosis, neutrophilia, and lymphopenia improvement (0.84 ±0.49, 13.05 ±6.44, 13.05 ±7.01, 13.05 ±7.01).The mean ±SD days of clinical versus CRP, D-dimer, s. ferritin, and LDH improvement (0.84 ±0.49, 12.2 ±3.25, 12.2 ±6.21, 12.3 ±5.46, 20.92± 9.48). The mean days of clinical versus radiological and electrocardiographic improvement (0.84 ±0.49, 15.74 ±5.25, 11.45 ±5.45). The test was statistically significant in all the above tests (p-value is < .00001) Conclusions: Yassers COVID-19 Discrepancy phenomenon is a novel descriptive phenomenon that is always seen in all COVID-19 pneumonia. Initial dramatic improvement of the clinical status of COVID-19 pneumonic patient, not a simultaneously after the management, not a coincide with laboratory, radiological, and electrocardiographic workup. Further larger studies for the study medical regimen with considering of “Yassers COVID-19 Discrepancy phenomenon” is recommended.

A term male infant was born by spontaneous vaginal delivery to a 23 year old gravida 2 para 2 mother. His weight, length, and head circumference were 2720g (8%), 47cm (6%) and 31.5cm (1%) respectively; the remainder of his physical examination was unremarkable. The pregnancy was complicated by intra-uterine growth retardation, gestational diabetes controlled with glyburide, and gestational thrombocytopenia. The mother had a past medical history of obesity, BMI of 32 (>95%), HPV infection, and atypical squamous cells of the cervix. A fetal ultrasound at 38 weeks gestational age showed echogenic foci consistent with cholelithiasis (Figure 1); a previous US at 37 weeks gestational age was normal. On routine laboratory testing the mother’s blood type was O positive and the infant’s was A+ (positive). His transcutaneous bilirubin was 4.3 mg/dL at 36 hours of life. Both mother and son were discharged after two days without problem.
