In China, Wuhan in the province of China, COVID-19 a patient suffering from pneumonia was tested and to identify the cause, the throat swab of the patient was tested. On 7th January 2020 WHO declared the identification as COVID-19. And then it was proclaimed as a pandemic. It classically causes a respiratory illness presenting as a mild cough, fever and . However, several investigators have advocated the involvement of the gastrointestinal tract and liver in COVID-19 infection similar to other infections. Further research studies have shown results that are expanding the possibility of transmission because RT-PCR assessment has shown significant evidence for the presence of virus not only in samples but also in stool samples. Studies have shown that virus in stool samples have got positive results even after the illness has resolved, and two respiratory tests were done 24 hours after COVID-19 being tested negative. The review article the different findings of the clinical presentation of COVID-19. It sheds light on the effects of COVID-19 in the gastrointestinal system along with the reasons for the high possibility of transmission of COVID-19 through the route.

This review article provides an overview of the etiology, pathogenesis, clinical presentation, diagnosis, and treatment methods for actinic keratosis, keratoacanthoma, and Bowen’s disease. The provoking factors are described, where the main importance is attached to insolation, previous immunosuppression and immunodeficiency and trauma. The pathogenesis of these diseases is described in the form of cascade models. Various clinical forms and their main dermatoscopic features, suitable for digital processing in automated diagnostic systems, are presented. A stepwise approach to the treatment of these nosologies is described, and a preliminary prognosis is assessed based on the duration of progression and the likelihood of transformation into squamous cell carcinoma. Given the fact that dermato-oncologists have not yet come to a consensus on the classification of the described diseases, in this article they are considered as a borderline, thereby demonstrating a fine line of transition from a precancerous state to cancer in situ.

Approximately over 500,000 children die annually due to severe dehydrating diarrhea caused by rotaviruses. This work investigated rotavirus infection among children less than 5 years with diarrhea in Lagos and determined the circulating electropherotypes and genotypes of the virus isolates. Three hundred and two (n=302) stool samples from children below 60 months were collected from different hospitals and health care centers in Lagos and subjected to enzyme immunoassay (EIA) to determine the presence of Group A rotavirus, RT-PCR to determine the G-types, and polyacrylamide gel electrophoresis (PAGE) to determine the electropherotypes. The results show that 60.3% of the samples showed distinct rotavirus RNA migration pattern, having long electropherotypes (55.3%) of seven variations dominating over the short electropherotypes (44.5%). Six different G-types were detected (G1, G2, G3, G4, G9, and G12). Serotypes G1 and G12 showed long electropherotypic pattern while G2, G3, and G9 exhibited either short or long electropherotype. All G4 detected show short electropherotypic pattern. In conclusion, information on the genomic diversity and RNA electropherotypes of rotaviruses detected in children with diarrhea in Lagos is reported in this study.

Since the mid-1980s there has been increasing interest in the effects of passive smoking on the health of children. It has been estimated that the total nicotine dose received by children whose parents smoke is equivalent to their actively smoking between 60 and 150 cigarettes per year. This review article considers the evidence for a relationship between passive smoking and disorders such as: prenatal damage to the fetus; poor growth indicators; respiratory illness; atopy and asthma; coronary heart disease; and sudden infant death syndrome. We conclude that paediatricians should not be complacent about the hazards of passive smoking for children and that public health education efforts should be continued

Objective: Although Covid-19 which has been identified as the disease caused by SARS COV-2 virus mainly affects the respiratory tract, it was observed that many systems were affected. The gastrointestinal system is one of the main systems involved. The aim of this manuscript was to perform epidemiological, virological, and clinical analysis of 59 Covid 19-positive patients with gastrointestinal symptoms. Method: Covid-19 diagnosed patients have been started to be admitted since March, 20, 2020. Epidemiological, demographical, clinical findings, laboratory analyses as well as hospitalization periods and disease progression of the patients presenting gastrointestinal system (GIS) symptoms admitted between March, 31, 2020 and August, 1, 2020. Results: Totally 710 Covid 19-positive patients hospitalized were screened. Among these patients, those with incomplete medical history and deficient data were excluded. The analysis of 281 patients admitted due to Covid-19 diagnosis with complete data since admission revealed that 59 patients presented GIS symptoms at admission. The aforesaid patients were compared with 222 patients admitted due to Covid-19 without GIS symptoms within the same period. GIS symptoms were detected on 59 (59/281) (20.99%) patients admitted due to Covid-19. Detailed review of these patients revealed that 18 (18/59) (30.50%) patients had nausea-vomiting, 10 (10/59) (16.95%) patients had abdominal pain, and 31 (31/59) (52.55%) patients had GIS bleeding. It was observed that vomiting was added into the clinical presentation in 7 of 18 patients. Although there is not any diarrhea symptom alone, total number of cases with diarrhea+abdominal pain, diarrhea+nausea-vomiting, diarrhea+nausea-vomiting+abdominal pain was 17 (17/59) (28.81%) of 59 patients. Conclusion: According to the results of this study, we have found 20.99% gi symptoms in the hospitalizated patients due to Covid 19. Although GIS symptoms are not associated with disease severity, they are important for the identification and spread of the disease, along with respiratory symptoms.

Abstract Background: Early and accurate identification of infection viruses among children can benefit the personalized medical treatment and management, and reduce the future occurrence of serious symptoms. Thus, it is critical to develop a high-throughput multiplex real-time RT-PCR method to improve the accuracy and efficiency in routine clinical lab tests. Here, we developed a RT-PCR combined with melting curve analysis (RRCMC) method for simultaneous detection of rotavirus A, B, C, norovirus GI and GII, adenovirus, astrovirus and sapovirus. Results: Stool samples were collected from 160 children with acute diarrhea and tested by RRCMC assay. A total of 71 patients were tested positive with norovirus, adenovirus or rotavirus. The RRCMC assay has high specificity. There is no internal cross-reaction through the 8 diarrhea viruses and no cross-reaction of other commonly intestinal pathogens and human genome. The detection limit was ranging from 1×102 to 1×105 copies/ml for each diarrhea virus. Conclusions: In conclusion, the RRCMC method is a suitable rapid clinical test for infection viruses, with the advantages of high-throughput, low cost, high sensitivity, and specificity.

Background: The recently launched high-throughput assays for the detection of antibodies against SARS-CoV-2 may change the managing strategies for the COVID-19 pandemic. This study aimed at investigating the performance of three high-throughput assays and one rapid lateral flow test relative to the recommended criteria defined by regulatory authorities. Methods: A total of 133 samples, including 100 pre-pandemic samples, 20 samples from SARS-CoV-2 RT-PCR positive individuals, and 13 potentially cross-reactive samples were analysed with SARS-CoV-2 IgG (Abbott), Elecsys Anti-SARS-CoV-2 (Roche), LIAISON SARS-CoV-2 S1/S2 IgG (DiaSorin) and 2019-nCOV IgG/IgM Rapid Test (Dynamiker Biotechnology Co). Results: All assays performed with a high level of specificity; however, only Abbott reached 100% (95% CI 96.3-100). The pre-pandemic samples analysed with Roche, DiaSorin and Dynamiker Biotechnology resulted in two to three false-positive results per method (specificity 96.9-98.0%). Sensitivity differed more between the assays, Roche exhibiting the highest sensitivity (100%, CI 83.9-100). The corresponding figures for Abbott, DiaSorin and Dynamiker Biotechnology were 85.0%, 77.8% and 75.0%, respectively. Conclusions: The results of the evaluated SARS-CoV-2 assays vary considerably as well as their ability to fulfil the performance criteria proposed by regulatory authorities. Introduction into clinical use in low-prevalent settings, should therefore, be made with caution.

Abstract Objective: Patients admitted to the hospital may unknowingly carry SARS-CoV-2 and hospitals have implemented SARS-CoV-2 admission screening. However, because SARS-CoV-2 RT-PCR may remain positive for months after infection, positive results may represent active or past infection. We determined the prevalence and infectiousness of patients who were admitted for reasons unrelated to COVID-19 but tested positive on admission screening. Methods: We conducted an observational study at the University of Iowa Hospitals & Clinics from July 7 to October 25, 2020. All patients admitted without suspicion of COVID-19 infection were included and medical records of those with a positive admission screening test were reviewed. Infectiousness was determined using patient history, PCR cycle threshold (Ct) value, and serology. Results: A total of 5,913 patients were screened and admitted for reasons unrelated to COVID-19. Of these, 101 had positive admission RT-PCR results. Thirty-six patient were excluded because they had respiratory signs/symptoms on admission on chart review. Sixty-five patients (1.1%) did not have respiratory symptoms. A total of 55 patients had Ct values available and were included in this analysis. The median age was 56 years, and (51%) were male. Our assessment revealed that 23 patients (42%) were likely infectious. The median duration of in-hospital isolation was five days for those likely infectious and two days for those deemed non-infectious. Conclusions: COVID-19 infection was infrequent among patients admitted for reasons unrelated to COVID-19. An assessment of the likelihood of infectiousness using clinical history, RT-PCR Ct values, and serology may help discontinue isolation and conserve resources.

Idiopathic thrombocytopenic purpiira (ITP), also known as primary immune or autoimmune thmmbocytopenic purpura, is a common cause of thrombocytopenia and bleeding complications in children and adults. It mav be confused with other causes of thrombocvtopenia and is treated with agents that varv in efjicacv, toxicity, and cost. Clinical presentation very in children and adult. In children, ITP is usually an acute, self-limited disorder that resolves spontaneously: in adults, it is typically a chronic disorder with a more insidious onset. In about one third of adults with ITP, the condition is persistent and relatively resistant to most treatments .Available evidence suggests that only about 5% of adults with chronic ITP have spontaneous remission. The principal therapeutic options for ITP include glucocorticoids, intravenous immunoglobulin and splenectomy. Other treatments have been used for refractory cases; these include intravenous anti-Rh (D), azathioprine, cyclophosphamide, danazol, vinca alkaloids, ascorbic acid, colchicine, interferon-alpha, combination chemotherapy, protein A, immunoadsorption, cyclosporine, epsilon-aminocaproic acid, plasma exchange, and accessory splenectomy.
