Rapidly progressive precocious puberty during the COVID-19 lockdown. / Pubertad precoz y pubertad rápidamente progresiva durante el confinamiento por la pandemia por COVID-19.

Introduction. During the COVID-19 pandemic, an increase in consultations for precocious puberty (PP) was observed. Our objective was to determine the frequency of PP and its progression before and during the pandemic. Methods. Retrospective, observational, analytical study. The medical records of patients who consulted with the Department of Pediatric Endocrinology between April 2018 and March 2021 were assessed. Consultations for suspected PP during the pandemic (period 3) were analyzed and compared to the 2 previous years (periods 1 and 2). Clinical data and ancillary tests done in the initial assessment and PP progression information were collected. Results. Data from 5151 consultations were analyzed. An increase in consultations for suspected PP was observed during period 3 (21% versus 10% and 11%, p < 0.001). Patients who consulted for suspected PP during period 3 increased 2.3-fold (80 versus 29 and 31, p < 0.001). In total, 95% were female; this was the population analyzed. We included 132 patients with similar age, weight, height, bone age, and hormonal characteristics in the 3 periods. During period 3, a lower body mass index, a higher percentage of Tanner breast stage 3-4, and a greater uterine length were observed. Treatment was indicated upon diagnosis in 26% of the cases. In the rest, their evolution was monitored. During follow-up, a rapidly progressive course was observed more frequently in period 3 (47% versus 8% versus 13%, p: 0.02). Conclusions. We observed an increase in PP and a rapidly progressive evolution in girls during the pandemic.

Assessment of Potential Risk Factors, Characteristics, and Outcome of Pneumothorax and Pneumomediastinum in Patients with COVID-19: A Retrospective Case-control Study

Introduction: Pneumothorax (PTX) and/or pneumomediastinum (PMD) are rare complications of Coronavirus Disease-2019 (COVID-19) and are linked to high mortality. Incidence rates vary between 0.56-2.01% in the reported literature. With clinical examination being hampered in the current pandemic setting, there is a delay in the diagnosis. There is a need to identify and establish potential predictive factors, that may aid in identifying patients with a high-risk of developing PTX and/or PMD. Aim: To identify potential risk factors and thus, explore their association with PTX and/or PMD among patients with COVID-19. Materials and Methods: A retrospective case-control study was conducted at MS Ramaiah Medical College and Hospital, Bangalore, South India over a six-month period. A total of 130 patients diagnosed with COVID-19 were recruited in a 1:3 ratio as cases and controls respectively. Cases were patients, diagnosed radiologically with PTX and/or PMD, and controls were, matched individuals without PTX and/or PMD. Patient's clinical and laboratory parameters (complete blood count, renal and liver function tests, serum levels of inflammatory markers such as C-reactive protein (CRP), lactate dehydrogenase (LDH), and D-Dimer were tested for potential association with PTX and/or PMD. Student's t-test, Chi-square test, multivariate and univariate logistic regression analysis were performed. Results: During the study period, there was a total of 3,251 COVID-19 admissions at the centre with 976 patients requiring Intensive Care Unit (ICU) admission. The overall incidence of PTX and/or PMD during the study period was (31/3251) 0.95%. The previous history of COVID-19, non vaccination with COVID-19 vaccine, cough as a predominant symptom, high values of baseline CRP, total bilirubin, Aspartate Transaminase (AST), and total leukocyte counts had a positive association. In-hospital mortality (54.8% vs 33.30%) and mortality 28 days (35.7% vs 7.6%) following discharge, were higher among those with PTX and/or PMD. Conclusion: Patients with a history of previous infection with COVID-19, non vaccination/incomplete-vaccination with COVID-19 vaccines, and patients with increasing total leukocyte counts and AST levels, high baseline total serum bilirubin were at increased risk of a detrimental clinical course and may indicate, the possibility of development of PTX and/or PMD in COVID-19 disease.

INFECTIONS IN KIDNEY TRANSPLANT RECIPIENTS :SINGLE CENTER EXPERIENCE FROM TERTIARY CARE CENTER IN SOUTH INDIA

Introduction: Infections occurring in the post transplant period are the major cause of morbidity and mortality in renal transplant recipients. Early infections (within the first month) are more likely to be due to nosocomially acquired pathogens, surgical issues, and donor-derived infections. Opportunistic pathogens occur after 6 months, reflects the greater impact of immunosuppressive therapies. Late infections may be secondary to opportunistic pathogens or conventional ones. Methods: It is a retrospective observational study.All hospitalised patients with infections were included between November 2019 to march 2022 excluding covid 19 infections.Infections were categorised based on time line of infection into less than one month, 1-6 months and more than 6 months and sub categorised based on type of organisms and source of infection.All baseline characteristics, labs, microbiological including serology, PCR and cultures, radiological findings and histopathological findings were noted.Complications including graft dysfunction and need for various supports such as O2, ionotropes, ventilator and dialysis and treatment details and in hospital patient outcomes were analysed using descriptive statistics. Results: 53 patients admitted with infection in the given period were included in the study.Among them 88.67% were males and 11.33% females. In the study population 66.03 % underwent live related renal transplant and 33.97% underwent deceased donor transplantation. Mean age of the study population was 35.2 years. There were 118 events of infection identified during the study period.UTI was the most common post-transplant infection and occurred in 36.44 % of total events. There were 13 events of post-transplant infection in the first month. Most common infection in early post-transplant period was UTI, 53.84 % of events of UTI occurred followed by pneumonia in 23.07% of total events. E coli was isolated in 57.14 % of events There were 48 events of infections in the period of 1- 6 months.UTI was the most common infection (37.5 % of total events ) and E coli was the most common organism isolated(44.44 %). Pneumonia was the second commonly occurred event in 18.75 % of total events and Klebsiella was the most common isolated ( 55.56 % ).CMV disease was identified in 10.41% events, 40 % had tissue invasive CMV, 60% presented with cytopenia. There were 57 events of infections after 6 months, UTI was the most common infection(31.57% events) and E coli was the most common organism (44.00%).Pneumonia occurred in 19.29% followed by skin and soft tissue infection (13.94 %)herpes zoster ( 8.75% ) gastroenteritis(7.01%), BKVN (5.26%),oral candidiasis (3.50%)CMV disease (3.50%), tuberculosis(3.5%), meningitis (1.75%) and dengue(1.75%). 95.76% of infectious event was associated allograft dysfunction and 22.64 % of the study population had PTDM. In 15.25 % of events, patients had septic shock at presentation.Amongst them 44.44% had urosepsis, 33.33% had pneumonia, 22.22% had acute gastroenteritis. 18.86 % expired during hospital stay,amongst them 60 % had pneumonia and 30% had urosepsis and 10% had acute gastroenteritis.

Clues from the Pandora's Box: Frequency of Acute Abdominal Symptoms in COVID-19 and Its Association with Inflammatory Markers-a Cross-Sectional Study.

Coronavirus disease 2019 (COVID-19) is primarily considered to be a respiratory ailment. Hitherto, abdominal symptoms have been reported with variable frequency in acute COVID-19. The purpose of this study was to estimate the frequency of abdominal symptoms at presentation among patients hospitalised with COVID-19 infection, and to determine their association with disease severity. This was a single-centre cross-sectional observational study conducted at a COVID-19 tertiary care hospital (CTRI/2021/10/037195, registered on 08/10/2021). Consecutive patients hospitalised with acute COVID-19 illness during the study period were included in the study. Their demographic information, abdominal symptoms, comorbidities and category of COVID-19 illness were elicited. All patients had serum inflammatory markers tested on the day of hospitalisation. Among the 685 participants, 214 patients had mild-to-moderate category illness whereas the rest 471 had severe COVID-19 illness. Abdominal complaints were present among 132/685 (18.3%) patients with distension of abdomen (8.03%) being the most common symptom, followed by vomiting (6.72%) and abdominal pain (3.94%). At admission to the hospital, abdominal complaints were commoner among patients with severe disease than in those with mild-to-moderate disease (101/471 vs. 31/214; p=0.029). Abdominal symptoms were associated with a higher neutrophil to lymphocyte ratio (p=0.029). The mortality among COVID-19 patients with abdominal symptoms was higher (9.09 vs. 3.25%; p = 0.007). This study demonstrates the spectrum of abdominal symptoms that can be a part of acute COVID-19 at hospitalisation and also highlights their prognostic potential in acute COVID-19 infection.

Temporal trends in legionellosis national notification data and the effect of COVID-19, Switzerland, 2000-2020.

The notification rate of legionellosis in Switzerland and other European countries has markedly increased over the last 20 years. Here, we investigated the Swiss notification data on legionellosis from 2000 to 2020 in regards of overall time trend, content and data quality. We further explored the impact of the COVID-19 pandemic on the reported case numbers using an interrupted time series approach. Between 2000 and 2020, 5980 cases were included in our analysis. The annual crude notification rate for legionellosis cases increased from 1.1/100,000 population (CI: 0.9-1.4) in 2000 to 5.6/100,000 population (CI: 5.1-6.1) in 2020. In recent years, the summer peaks have been more pronounced and some shifted earlier in the year. The highest notification rate was recorded in 2018 with 6.7/100,000 population (CI: 6.2-7.3). The hospitalisation rate for notified cases remained high across all study years (89.9%), while the case fatality rate slightly decreased (from 7.7% to 3.6%). COVID-19 containment measures, such as travel restrictions and/or related behavioural changes, are associated with a temporary decline in cases of 35%. Overall, the quality of the notification data was good. Clinical data were more susceptible to interferences than data from laboratory reporting, which could be observed most clearly in the decline of clinical reports by 4.3 percentage points in 2020. As the case classification for Legionnaires' disease includes pneumonia symptoms, this decline could lead to an underestimation of Legionnaires' disease cases, yet the continuous reporting though the diagnostic laboratories suggested a robust surveillance system for legionellosis in Switzerland.

Simian Immunodeficiency Virus Infection Mediated Changes in Jejunum and Peripheral SARS-CoV-2 Receptor ACE2 and Associated Proteins or Genes in Rhesus Macaques.

Angiotensin converting enzyme-2 (ACE2) and associated proteins play a pivotal role in various physiological and pathological events, such as immune activation, inflammation, gut barrier maintenance, intestinal stem cell proliferation, and apoptosis. Although many of these clinical events are quite significant in SIV/HIV infection, expression profiling of these proteins has not been well reported. Considering the different pathological consequences in the gut after HIV infection, we hypothesized that the expression of ACE2 and associated proteins of the Renin-angiotensin system (RAS) could be compromised after SIV/HIV infection. We quantified the gene expression of ACE2 as well as AGTR1/2, ADAM17, and TMPRSS2, and compared between SIV infected and uninfected rhesus macaques (Macaca mulatta; hereafter abbreviated RMs). The gene expression analysis revealed significant downregulation of ACE2 and upregulation of AGTR2 and inflammatory cytokine IL-6 in the gut of infected RMs. Protein expression profiling also revealed significant upregulation of AGTR2 after infection. The expression of ACE2 in protein level was also decreased, but not significantly, after infection. To understand the entirety of the process in newly regenerated epithelial cells, a global transcriptomic study of enteroids raised from intestinal stem cells was performed. Interestingly, most of the genes associated with the RAS, such as DPP4, MME, ANPEP, ACE2, ENPEP, were found to be downregulated in SIV infection. HNFA1 was found to be a key regulator of ACE2 and related protein expression. Jejunum CD4+ T cell depletion and increased IL-6 mRNA, MCP-1 and AGTR2 expression may signal inflammation, monocyte/macrophage accumulation and epithelial apoptosis in accelerating SIV pathogenesis. Overall, the findings in the study suggested a possible impact of SIV/HIV infection on expression of ACE2 and RAS-associated proteins resulting in the loss of gut homeostasis. In the context of the current COVID-19 pandemic, the outcome of SARS-CoV-2 and HIV co-infection remains uncertain and needs further investigation as the significance profile of ACE2, a viral entry receptor for SARS-CoV-2, and its expression in mRNA and protein varied in the current study. There is a concern of aggravated SARS-CoV-2 outcomes due to possible serious pathological events in the gut resulting from compromised expression of RAS- associated proteins in SIV/HIV infection.

COVID-19 risks and extra-protective measures practised among Nigerian orthodontists and orthodontic residents.

BACKGROUND AND AIMS: There is a high possibility of transmitting the coronavirus (severe acute respiratory syndrome coronavirus 2) in the orthodontic clinic because orthodontists and their patients are in very close contact when orthodontic care is being given. The aim of this study was to evaluate the knowledge and perception of Nigerian orthodontists and orthodontic residents about the risks of COVID-19 as well as the extra-protective infection control measures that need to be taken. MATERIALS AND METHODS: This was a descriptive, cross-sectional study. The questionnaires were distributed and retrieved from consenting participants through an online platform. The questionnaires were analysed using the Statistical Package for the Social Sciences software version 23. The results were presented in tables and charts. RESULTS: Out of a total of 90 members on the association's WhatsApp group as at the time the study was being conducted, a total of 48 respondents participated in this study. There were more females (60.4%) than males. Majority (97.9%) of the respondents agreed/strongly agreed that an infected patient could infect the orthodontic clinic staff members with COVID-19 while most were of the view that debonding (95.8%) and retainer delivery (70.8%) posed a risk for spread of the virus. More than half of the respondents (52.1%) considered it necessary to change N95 masks after each patient as an extra-protective measure against COVID-19. CONCLUSIONS: Majority of the respondents knew about the risks that COVID-19 posed to different aspects of orthodontic practice and were also knowledgeable about some of the extra-protective measures that they should take. There is a need to improve the knowledge of the participants concerning the use of appropriate mouth rinses to reduce the risks of transmission of COVID-19 in the dental/orthodontic clinic.

New onset diabetes with diabetic ketoacidosis in a child with multisystem inflammatory syndrome due to COVID-19.

INTRODUCTION: Multisystem inflammatory syndrome in children (MIS-C) is a unique clinical complication of SARS-CoV-2 infection observed in pediatric patients. COVID-19 is emerging as a potential trigger for the development of diabetes in children. Here, we report a patient presenting with MIS-C and new onset diabetes, and discuss the implication and clinical management of these concomitant conditions. CASE PRESENTATION: An eight-year-old female presented with hyperglycemia, ketosis and metabolic acidosis consistent with diabetic ketoacidosis (DKA) in the setting of fever, rash, respiratory distress, hemodynamic instability, reduced systolic function with dilation of the left anterior descending artery, and positive SARS-CoV-2 antibodies suggestive of MIS-C.
