New Onset Diabetes and Acute Pancreatitis- A Sequela of Long COVID?

Introduction: The association between worse COVID-19 outcomes and diabetes has been well-established in the literature. However, with more cases of new-onset diabetes and pancreatitis being reported with or after COVID-19 infection, it poses the question if there is a causal relationship between them. Case Description: 31 y/o female with COVID-19 infection 4-6 weeks ago with moderate symptoms (not requiring hospital admission or monoclonal ab), presented to ED with bandlike epigastric pain radiating to back, which is worsened with food, associated with nausea, vomiting, polyuria, and fatigue. Workup showed lipase 232, AST 180, ALT 256. Blood glucose was 281 and HbA1c was 12. CT A/P showed post cholecystectomy status, normal pancreas with mesenteric adenitis. MRCP showed hepatic steatosis with trace fluid around the pancreas s/o inflammation, and no evidence of choledocholithiasis or biliary dilatation. She denied alcohol use and autoimmune workup for pancreatitis was unremarkable. Islet cell antibodies were negative. The patient improved with fluid resuscitation and was discharged home on insulin with plans to transition to oral agents outpatient. Discussion(s): Long COVID is defined as a range of conditions or symptoms in patients recovering from COVID-19, lasting beyond 4 weeks after infection. A retrospective cohort study showed increased new-onset diabetes incidence in patients after COVID-19. This was redemonstrated in a systematic review and meta-analysis that showed a 14.4% increased proportion of new diagnoses of diabetes in patients hospitalized with COVID-19. Possible pathophysiology that have been attributed to this include undiagnosed pre-existing diabetes, hyperglycemia secondary to acute illness and stress from increased inflammatory markers during the cytokine storm, the effect of viral infections on the pancreas, and concurrent steroid use in patients with severe respiratory disease. The binding of SARS-CoV-2 to ACE2 receptors is thought to the other mechanism by which COVID can cause pancreatitis and hyperglycemia. Study showed increased lipase and amylase levels in patients with COVID and the increase in serum levels was proportional to the severity of the disease. Patients who died due to COVID-19 were also found to have degeneration of the islet cells. While, several studies have showed new onset diabetes and pancreatitis during an active COVID infections, we need larger cohort studies to comment on its true association or causation, especially in patients with long COVID symptoms. As more cases of new onset diabetes and pancreatitis with COVID-19 are being reported, there may be a need for more frequent blood sugar monitoring during the recovery phase of COVID-19.Copyright © 2023

Kikuchi-Fujimoto Disease Following COVID-19 Vaccination: Experience at a Population-Based Referral Center

Objectives: Multiple case reports describe Kikuchi-Fujimoto disease (KFD) following COVID-19 vaccination, but the true nature of this phenomenon is unknown. The purpose of this study was to further assess the relationship between KFD and COVID-19 vaccination at the population level.Methods: Confirmed KFD cases from January 2018 to April 2022 were identified from provincial pathology archives and analyzed in the context of vaccination statistics from public health resources.Results: Our statistical models provide evidence of a temporal association between KFD and both antecedent COVID-19 vaccine administration as well as age-stratified vaccination rates. Eight new cases of plausible COVID-19 vaccine-associated KFD are presented, collectively exhibiting clinical and pathologic features that overlap substantially with those of idiopathic KFD.Conclusions: Our findings indicate that KFD is observed in association with COVID-19 vaccination and suggest that mechanistic studies are warranted.

Human Monkeypox Virus (hMPXV) Remerges-Another Global Health Concern during the COVID-19 Disaster

The increase in human monkeypox virus (hMPXV) cases amidst the COVID-19 pandemic has raised fear among the general public. The monkeypox virus and the now-extinct smallpox virus belong to the orthopox family of viruses. Although first discovered in 1958, Monkeypox was only well recognized outside the sub-Saharan African countries until the world experienced a monkeypox pandemic in May 2022. The virus is common in some areas of Africa and is often spread through close contact with an infected person or animal. However, recent international trade, travel, and tourism developments have caused viral outbreaks outside Africa. The most recent pandemic in 2022 has been strange because epidemiologists have not found a link between cases and the virus's ability to spread through sexual contact. The structural and pathogenic activities of the virus that attack host cells need to be better understood. Because of this, it is important to know how viruses and the immune system work together to develop effective ways to treat and prevent diseases. To summarize existing research on Monkeypox, we conducted a narrative review using the MEDLINE, EMBASE, PUBMED, and Scopus databases to look at simultaneous zoonotic pandemics caused by the SARS-CoV-2 or COVID-19 coronavirus and presented the most to date information on the symptoms, epidemiology, diagnosis, prevention, and treatment of Monkeypox. However, more research on epidemiological details, ecology, and virus biology in endemic areas is required to understand the virus better and prevent further human infection. This short review discusses the research results that have already been published about how the monkeypox virus affects humans. © 2023, Liaquat University of Medical and Health Sciences.

Kikuchi-Fujimoto Disease: A Case of SARS-CoV-2 Infection Triggering the Rare Disease.

Kikuchi-Fujimoto disease (KFD), or histiocytic necrotizing lymphadenitis, is a rare, benign, and self-limited disease caused by subacute necrotizing regional lymphadenopathy. The etiology is unknown, although virus and autoimmune mechanisms have been proposed. Patients develop enlarged lymph nodes, fever, and, less frequently, extranodal signs. No specific laboratory test contributes to the diagnosis, and lymph node biopsy is the gold standard to define the diagnosis. The treatment is generally with supportive therapy and usually is spontaneously resolved within six months.  In this article, the authors present the case of a 41-year-old female with mild SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection 10 weeks before she was admitted to the emergency department (ED) due to cervical lymphadenopathies and fever lasting over three weeks. Physical examination revealed multiple lymphadenopathies on the submandibular and jugular regions, cutaneous rash, and hepatosplenomegaly. Blood tests showed elevated acute phase proteins, thrombocytopenia, and increased transaminases and lactate dehydrogenase (LDH). Computed tomography (CT) of the neck showed multiple adenopathies at levels I, II, III, and IV according to the Classification for Lymph Nodes from the American Head and Neck Society and American Academy of Otolaryngology on the right side. Excision biopsy was performed and histopathological examination confirmed KFD. A comprehensive analysis performed was unrevealing of an infectious or autoimmune cause and was assumed to be most likely triggered by SARS-CoV-2 infection given the timeframe correlation. KFD diagnosis is challenging and there are few reported cases of association with SARS-CoV-2 in the literature. Although further investigation is still needed to better understand the relation between them, it is important that physicians take SARS-CoV-2 infection and vaccination into consideration in KFD's differential diagnosis.

Kikuchi-Fujimoto disease type lymph node reaction with increased plasmacytoid dendritic cells may appear as a side effect following COVID-19 vaccination: Report of a case and literature review

Subsequent to mass vaccination programs against COVID-19, diverse side effects have been described, both at the injection site, such as pain, redness and swelling, and systemic effects such as fatigue, headache, muscle or joint pain. On rare occasions, a lymphadenopathic syndrome may develop, raising the clinical suspicion of a lymphoproliferative disorder. We present the case of a 30-year-old woman who developed self-limiting left axillary lymphadenopathy following COVID-19 vaccination. To date, only seven similar cases with a complete clinicopathological description have been published, and fourteen cases have been notified to the European adverse events databases (Eudravigilance) in relationship with vaccination against COVID-19. It is important to be aware of this potential complication when a lymphadenopathic syndrome develops following vaccination, to avoid unnecessary treatment.Copyright © 2023 Sociedad Espanola de Anatomia Patologica

X-Linked Inhibitor of Apoptosis (XIAP) deficiency presenting as hemophagocytic lymphohistiocytosis triggered by drug allergy

X-linked inhibitor of apoptosis (XIAP) deficiency is a primary immunodeficiency associated with recurrent hemophagocytic lymphohistiocytosis (HLH) episodes. The clinical phenotypes of XIAP deficiency vary, ranging from splenomegaly to life-threatening inflammation. We report a case of XIAP deficiency with unusual late-onset HLH presentation likely triggered by a drug allergy. A previously healthy adolescent boy presented to the hospital with fever and rash seven days after starting antibiotics for a neck abscess. Laboratory evaluation demonstrated cytopenias, elevated liver enzymes, and increased inflammatory markers. Initially, antibiotics were discontinued due to concern for drug rash. He continued to deteriorate clinically and became hypotensive. Additional testing revealed decreased NK cell function, as well as elevated ferritin, triglycerides, and soluble IL-2 receptor. SLAM-Associated Protein (SAP) and XIAP evaluation by flow cytometry demonstrated decreased XIAP expression. Subsequently, genetic testing revealed a known pathogenic mutation in BIRC4 (c.421_422del), confirming the diagnosis of XIAP deficiency.Copyright © 2023

Reactivation of Tuberculosis and COVID-19 in Pediatric Patients

Objective Mycobacterium tuberculosis is an immobile aerobic bacillus that causes tuberculosis (TB) disease. We aimed to evaluate the association between coronavirus disease 2019 (COVID-19), COVID-19-related drugs, TB reactivation, and TB incidence during the pandemic. Methods Eight patients who were diagnosed as having TB in Meram Medical Faculty, Necmettin Erbakan University between March 1, 2020, and December 31, 2021, at the beginning of the pandemic, were enrolled in this study. The presence of COVID-19 infection was confirmed using COVID-19 antibody tests and the patients' COVID-19 history. We evaluated the demographic data, laboratory findings, imaging tests, and pathology results of all patients. Results We checked all our patients with TB using COVID-19 antibodies (immunoglobulin [Ig]G + IgM) or polymerase chain reaction. Seven of the eight patients were female (87.5%). The median age was 16 years. Family screening of all patients was negative, and they had bacillus Calmette-Guerin vaccine scars. Two patients had chronic diseases. One was diagnosed as having primary ciliary dyskinesia in our department (patient no. 8) and the second was under follow-up by the rheumatology department with a diagnosis of juvenile idiopathic rheumatoid arthritis. Conclusion There has been an increase in the incidence of TB in children, especially in adolescents, during the pandemic period. This may be due to the pathogenic structure of the COVID-19 virus with an unknown mechanism. In addition, lifestyle changes and changes in health care policies during the pandemic may have caused this. Further research should be performed on this topic.Copyright © 2023 Authors.

Group A Streptococcus Necrotizing Lymphadenitis: A Case Report.

Necrotizing lymphadenitis (NL) is a rare entity that can occur as a complication of bacterial cervical lymphadenitis (CL) and is characterized by unilateral or bilateral cervical lymphadenopathy. NL most commonly presents in females and most reports have been in Japan. In this case, we present a 37-year-old male with no significant past medical history who presented with an unusual presentation and clinical course of NL. Initial workup for Epstein-Barr Virus (EBV) and other infectious etiology was negative. Yet, aspiration later revealed Group A Streptococcus. When the patient's pain and swelling did not subside with the initial antibiotic and supportive treatment, the patient underwent a repeat aspiration and biopsy that revealed a necrotic mass or lymph node. NL is uncommon and rarely due to infectious etiology. However, this marks a case in which a Group A Streptococcus was shown to be associated with subsequent necrotic lymph nodes and should allow practitioners to further consider an infectious etiology in the differential diagnosis of NL.

SARS-CoV-2-fertozés okozta Kikuchi-Fujimoto-betegség sikeres gyógyítása.

The Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis) is an autolimited process, which can be caused by viral agents like Epstein-Barr virus, human herpes virus, HIV, B19 parvovirus, paromyxoviruses, SARS-CoV-2, Toxoplasma and Yersinia. The correct diagnosis is based on histological findings. A 45-year-old female patient presented in our ambulatory room with a unilateral neck mass, fever, dysphonia and dysphagia. The patient was double-tested positive for SARS-CoV-2 approximately 1 month before the symptoms started. Before examination, the nasopharyngeal rapid test for SARS-CoV-2 resulted negative. After hospitalization, intravenous antibiotic (Augmentin, 3 × 1.2 g; Klion, 2 × 100 mg) and steroid (Solu-Medrol, 2 × 125 mg) therapy were administered. The neck and chest CT described a right-sided retropharyngeal abscess with bilateral neck lympadenopathy. Urgent tracheotomy, neck dissection and lymph node biopsy were made. The intraoperative findings excluded the presence of the abscess. The histological findings confirmed the necrotizing histiocytic lymphadenitis. Despite of the fact that the Kikuchi-Fujimoto disease is autolimited, we can see that, in this particular case, the lymphadenopathy after the SARS-CoV-2 infection caused a life-threatening situation. The formed extratissular liquid imitated the image of a retropharyngeal abscess. In the searched worldwide literature, similar intervention for this type of process was not described. Tracheotomy, neck dissection and removing the lymph nodes as ,,trigger zones" caused the full recovery of the patient. In the future, we consider important proving and clarifying the correlation between SARS-CoV-2 and Kikuchi-Fujimoto disease. Orv Hetil. 2022; 163(27): 1061-1065.

Kikuchi-Fujimoto disease following COVID-19 infection in a 13-year- old girl

Background/Purpose: Kikuchi-Fujimoto disease (KFD) is a rare, self-limited histiocytic necrotizing lymphadenitis. Although it is of uncertain aetiology, it is associated with viral infections and autoimmune diseases. Hence, it is crucial to identify KFD from other conditions with lymphadenopathy. Here we present a case of KFD after COVID-19 infection. Method(s): Medical records were traced and reviewed Results: A previously healthy 13-year- old girl was admitted in April 2022 with four weeks of fever, dry cough, loss of weight, followed by 1 week history of painful cervical lymphadenopathy and nonspecific maculopapular rash. She received her second dose of Covid 19 vaccine in January 2022. Unfortunately, she was diagnosed with CAT II, COVID 19 infection in March 2022. There was no history of allergy, recent traveling and cat scratch injury. Clinically there was no strawberry tongue, erythema of the lips, conjunctivitis or distal extremities changes to suggest Kawasaki disease. She was initially diagnosed with infection related lymphadenitis, treated with oral azithromycin for three days and intravenous ceftriazone for one week with no improvement. Her laboratory results showed hypochromic microcystic anaemia with leucopenia, raised inflammatory markers and lactate-dehydrogenese levels. Extensive workup for infection was unremarkable. Immunology test showed ANA, ANCA, ENA were negative with normal complements. Ultrasound abdomen was normal. Excisional lymph node biopsy revealed confluent areas of necrosis surrounded by histiocytes (CD68+) with absent of neutrophils. No granuloma or atypical lymphoid cells seen. Based on histopathology report, diagnosis of KFD was established. As she was not able tolerate orally, IV hydrocortisone was started and subsequently switched to oral prednisolone. She responded well to corticosteroids with fever subsided within a day and cervical lymphadenopathy reducing in size and resolved in one month. Prednisolone was able to taper off by two months. She showed complete recovery with no recurrence during follow-up. Conclusion(s): In persistent febrile painful lymphadenopathy, excision lymph node biopsy is essential to establish definite diagnosis. This case highlights the possible association between COVID-19 and KFD.

Protein losing enteropathy (PLE) secondary to norovirus infection in a 4 year old patient

Case Report: Protein losing enteropathy (PLE) occurs when proteins leak from the gastrointestinal (GI) system more rapidly than they are produced. Inflammation of the GI tract facilitates increased membrane permeability of gastric mucosa, leading to excess protein leakage. 1 PLE in children has been associated with CMV, rotavirus, COVID-19, HIV, C. difficile, and autoimmune diseases like Crohn's Disease. 2-6 Norovirus is a known cause of PLE in immunocompromised pediatric patients. 7-8 However, to our knowledge, there are no case reports about PLE precipitated by norovirus in immunocompetent pediatric patients. The purpose of this case report is to present a case of PLE precipitated by a norovirus infection in a 4- year-old previously healthy child. While the above gastrointestinal viruses have been proposed as precipitators for this disease, PLE precipitated by norovirus infection has not been well described. This case also highlights the importance of early diagnosis and management to avoid complications. Method(s): Our patient initially presented with two days of abdominal pain, diarrhea, emesis, reduced urine output, and swelling of the lower extremities. He was exposed to several sick family members-his sister had upper respiratory symptoms and his grandmother had gastrointestinal symptoms. Physical exam was notable for diminished breath sounds in the right lower lobe, abdominal distension with diffuse tenderness and dullness to percussion, significant scrotal and penile edema, and bilateral lower extremity pitting edema. Laboratory results revealed leukocytosis, hypoalbuminemia, hyponatremia, elevated aspartate aminotransferase (AST), and elevated serum alpha-1-antitrypsin, as well as low Immunoglobulins G and M. CD3 and CD4 levels were low reflecting cellular immune dysregulation seen in patients with PLE. IgA and Tissue Transglutaminase (TTF) were within normal limits. Ebstein Barr Virus and cytomegalovirus IgM antibodies were negative. COVID IgG was negative as well. His Polymerase chain reaction (PCR) gastrointestinal panel was positive for norovirus. A chest X-ray showed a large right pleural effusion. Abdominal CT revealed large ascites slightly more predominant in the upper abdomen, mesenteric lymphadenitis, and bilateral pleural effusions. Echocardiogram showed small anterior and apical pericardial effusions. Result(s): Based on the patient's elevated serum alpha-1 antitrypsin levels, hypoalbuminemia, low levels of immunoglobulins and lymphocytes, and clinical manifestations of ascites, bilateral pleural effusions, pericardial effusion, and dependent edema, along with a positive PCR for norovirus, the diagnosis of PLE secondary to Norovirus was made. Conclusion(s): This case demonstrates the importance of recognizing viruses like Norovirus as potential causes of PLE to avoid a delay in diagnosis and initiation of therapy, and to avoid unnecessary additional testing.

Mesenteric Adenopathy and Adenitis

Mesenteric adenopathy and adenitis are common causes of abdominal pain, requiring emergency admission to hospital. The term mesenteric adenitis is generally used to denote painful lymphadenopathy due to viral infection and is mostly associated with self-limiting viral infections. However, mesenteric adenopathy and adenitis can be associated with infection with SARS-Cov-2 or the human immunodeficiency virus in which setting these have a particularly poor prognosis. Recent advances in our understanding of the mesentery and the organisation of the human body shed new light on the position of mesenteric adenopathy and adenitis in disease in general. Both these abnormalities of the mesentery are observed in most diseases of the abdomen. The frequency with which they are observed means there is an increasing need to scientifically and clinically investigate both. Improved understanding of mesenteric adenopathy and adenitis is likely to greatly enhance our understanding of abdominal and systemic diseases in general. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Tender cervical lymphadenitis as a herald of multi-system inflammatory syndrome in COVID-19 infection of children and adolescents: a report of two cases.

BACKGROUND: Post-COVID-19 multisystem inflammatory syndrome (MIS) has been increasingly recognized but fever with isolated tender cervical lymphadenitis as the initial presentation has been rarely reported. We present 2 female patients one a child and the other an adolescent. CASE PRESENTATION: Case 1 was a 13-year-old girl who presented with tender cervical lymphadenopathy and fever 3-weeks post-COVID-19, and then developed features of MIS 5 days later. Case 2, also female, was 18 years old. She had no history of COVID-19 infection or immunization but had a serologic diagnosis of COVID-19. She similarly presented with fever and tender cervical lymphadenopathy, and then progressed rapidly to develop features of MIS. Both patients responded well to treatment with immunosuppressants and intravenous immunoglobulin. CONCLUSION: Tender cervical lymphadenopathy could be the herald of multi-system inflammatory syndrome following COVID-19 infection among children and adolescents, which the clinicians must have a good suspicion about.

Purulent lymphadenitis due to Halomonas hamiltonii: a case report.

Halomonas hamiltonii is a gram-negative rod bacterium isolated from highly saline environments. H. hamiltonii has rarely been reported as a human pathogen. Herein, we present the first case report of a purulent lymphadenitis caused by H. hamiltonii worldwide. The patient was a previously healthy girl aged 1 year who was referred to our hospital for left axillary lymphadenitis. Although oral amoxicillin was administered, lymphadenitis did not improve, and an abscess developed. After incision and drainage, the abscess was reduced. No recurrence of lymphadenitis was observed. The pus culture was negative. However, the 16S ribosomal DNA was amplified by the melting temperature mapping method. The amplified 16S ribosomal DNA sequence revealed 99.7% identity of H. hamiltonii. To the best of our knowledge, this is the first case of H. hamiltonii infection in a lymph node. This pathogen should be considered when diagnosing purulent lymphadenitis in healthy patients with lymphadenopathy of unknown origin.

ROCK AND ROLL AND LASER IN BETWEEN: BRONCHOSCOPIC LITHOTRIPSY

SESSION TITLE: Case Reports of Procedure Treatments Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: Broncholiths are calcifications in the tracheobronchial tree that are most commonly associated with indolent infections. Disease manifestations range from asymptomatic stones in the airway to major complications such as massive hemoptysis or post-obstructive pneumonias. Depending on severity of the disease, patient management can range from conservative strategies to surgical interventions. We report successful reduction of a large obstructive broncholith in the right middle lobe via Holmium-yttrium aluminum garnet (Ho:YAG) laser lithotripsy. CASE PRESENTATION: Patient is a 55 year old male who presented with on going purulent cough, fever and pleuritic chest pain for 3 months. He had associated weight loss (>10 lbs in 3 months), malaise, increased fatigue, and scant hemoptysis. Initial chest x-ray was evident of right middle lobe consolidation. Respiratory infection panel, COVID PCR, AFB cultures and fungal cultures were negative. Subsequent CT of his chest showed right middle lobe opacities with areas of obstruction with a broncholith. Subsequently, patient underwent rigid bronchoscopy to allow for left sided airway protection via direct tamponade if patient develops massive hemoptysis. A bronchoscopic inspection was performed through the rigid scope that confirmed the broncholith. Obliteration of broncholith was then performed via Ho:YAG. After multiple laser treatments, we noted improvement in the size of the broncholith. Patient admitted to significant improvement in chest pain, hemoptysis and cough since the procedure. DISCUSSION: Broncholithiasis refers to calcified material eroding the tracheobronchial tree and causing inflammation and obstruction. Etiology of broncholiths include calcified peribronchiolar lymph nodes that erode into the airway lumen. Lymph node calcifications in the thorax are associated with lymphadenitis from fungal or mycobacterial infections. Management depends on the size of broncholiths. For larger stones, flexible bronchoscopy is often used to confirm diagnosis. When forceps extraction is not feasible, stone fragmentation with Ho:YAG is generally utilized, but they carry the risk of massive hemoptysis or bronchial injury. Surgical interventions, such as lobectomy or pneumonectomy, are reserved for patients with recurrent pneumonias, bronchiectasis, bronchial stenosis or broncho-esophageal or aorto-tracheal fistulas. In our case, we demonstrate successful reduction of a non-mobile broncholith by protecting the airway using rigid bronchoscopy by interventional pulmonology and subsequently avoiding surgical intervention in a patient with repeated post-obstructive pneumonia. CONCLUSIONS: Management of broncholiths should be individualized for symptomatic patients. A comprehensive assessment with appropriate imaging and involvement of interventional pulmonology can result in successful reduction of the stone and minimizing complications.

Functional Gastrointestinal Disorders as a Post-Covid Infection Sequel in Pediatric Patients in Mexico

INTRODUCTION: The rate of pediatric patients diagnosed with Sars Cov 2 has increased since the early stages of the pandemic. Gastrointestinal symptoms have been demonstrated to be relatively common in pediatric COVID-19 patients as well as severe complications like PIMS syndrome because of the expression of ACE II in different areas of the digestive tract which serves as a receptor for their entry and infection in the body. During the last months of the omicron variant wave, we observed some gastrointestinal conditions in pediatric patients days after the resolution of the Sars Cov 2 acute infection period, sparking our interest to execute further research and analysis. OBJECTIVE(S): Describe the presence of functional gastrointestinal disorders as a post-covid infection sequel METHODS: We performed a descriptive, cross-sectional, observational, retrospective study, were we recollected the clinical and epidemiological data from the medical records of pediatric patients with a history of Sars cov-2 infection confirmed with positive PCR or antigen (sars cov-2) tests at Hospital Angeles Lomas, Mexico City. We included children from 6 months up to 16 years of age, who presented functional gastrointestinal disorders at a minimum 15 days after the infection that fulfilled Rome IV criteria. We evaluated the frequency and proportion of the qualitative variables;we obtained the arithmetic mean and the standard deviation for the quantitative variables with normal distribution RESULTS: We included data from 30 patients with confirmed covid 19 diseases by positive pcr or antigen (sars cov-2) tests, with a mean age 5.327 +/- 3.8 years Min: 7 months Max: 16 years, with a female predominance of 56.7% vs 43% male patients. During the acute infection by covid, 20% presented respiratory symptoms, 13.3% gastrointestinal symptoms, 36.7% only fever, 3.3% dysgeusia and 26.7% were asymptomatic. Adequate nutritional status was detected in 93% of the patients. The mean days the patients presented manifestations was 32 +/- 14 days, at a minimum 15 days, with a maximum of 63 days, being the most frequent functional gastrointestinal disorders: abdominal pain 90%, bloating 76%, vomit and reflux 33%, diarrhea 30%, constipation 26.7%. There was no weight loss in the patients, the appropriate treatment was given for each case. There was no complication in 90% of the patients, 10% presented acute abdominal pain and were transferred to the emergency room, 1 patient was diagnosed with appendicitis and 2 patients with mesenteric lymphadenitis. CONCLUSION Special attention must be paid to toddler and preschooler patients with Sars Cov 2 infection, regardless of the clinical manifestation in acute infections, mild or asymptomatic, functional gastrointestinal disorders may occur in the first 2 months after a positive PCR test. The ileum and the colon are places in which there is a greater expression of the ACE II, so when the enterocytes are invaded by SARS CoV-2, they may produce alterations in absorption and other mechanisms that could be the cause of these consequences. It is of vital importance that all pediatricians are aware of the consequences of the disease to prevent misdiagnosis.

CAVITATORY LUNG RHIZOPUS INFECTION IN RENAL TRANSPLANT RECIPIENT: RARE CASE REPORT

Introduction: Mucormycosis is a life threatening fungal infection commonly seen in diabetics and immunocompromised individuals. It is caused by one of the members of mucoraceae family which includes mucor, rhizopus, rhizomucor, absidia and others. Its prevalence has become more common in covid pandemic. Methods: We report a rare case of large cavitatory Rhizopus infection in a renal transplant recipient. Patient was initiated on antitubercular therapy for tubercular lymphadenitis two months prior to transplant. He was given rabbit ATG as induction agent and was on triple maintenance immunosuppression with tacrolimus/ mycophenolate mofetil/ steroids. Patient developed post transplant Diabetes mellitus. Four months post transplant he presented with cough, fever and left sided chest and shoulder pain for 10 days. Covid RT PCR was done twice and it came out to be negative. High Resolution Computed tomography Chest revealed thick walled cavity abutting the chest wall (10.3 x 7.1cm) in left upper lobe. Blood culture was sterile after five days of incubation. Serum Beta galactomannan was negative. He was empirically started on broad spectrum antibiotics and antifungals (oral voriconazole). He underwent bronchoscopy on day 4 of admission. As tuberculosis was a differential, gene expert, tubercular culture and AFB stain was obtained on Bronchoalveolar(BAL) fluid which all came out to be negative. Microbiological sample from BAL Fluid revealed growth of Rhizopus species. He was started on Liposomal amphotericin B. Since the cavitatory lesion occupied almost the entire left lung, surgical resection was offered to the patient to which patient refused. Results: He improved symptomatically after 10 days of Liposomal amphotericin B. Total of 10 weeks of Liposomal amphotericin B was given. Follow up CT after 40 days showed significant reduction in size of cavity to 7.5cm. A surprising complete resolution of the lung cavity was seen after 4 months. Conclusions: This case is one of the very few reported cases of invasive pulmonary rhizopus infections. It emphasizes how medical treatment alone can lead to complete resolution of such large cavitatory lesions without surgical intervention. No conflict of interest

Kikuchi-Fujimoto Disease Following COVID-19 Infection in a 7-Year-Old Girl: A Case Report and Literature Review.

The coronavirus disease 2019 (COVID-19) symptoms in children are relatively mild and often do not require treatment. Nonetheless, complications caused by the immune response to COVID-19 in children are possible and diverse. We present the case of a 7-year-old girl with persistent fever and lymphadenopathy arising from SARS-CoV-2 infection, diagnosed with Kikuchi-Fujimoto Disease (KFD) on lymph node biopsy. KFD is a rare benign disease, clinically characterized by fever and tender cervical lymphadenopathy affecting posterior cervical lymph nodes. We also reviewed six previously reported cases of COVID-19-associated KFD that occurred in school-aged children and compared them with the present case. The clinical course of COVID-19-associated KFD was similar to that of previous reports of KFD with a favorable prognosis. This is the first report of a school-aged child developing KFD following SARS-CoV-2 infection. KFD should be considered when approaching patients with hyperinflammatory states who present with prolonged fever and cervical lymphadenopathy after COVID-19.

Unilateral lymphadenopathy in a child, another banal case of illness before the weekend?

Introduction Cervical lymphadenopathy is a common finding in the pediatric population and manifests itself uni- or bilaterally. The causes of an acute cervical lymphadenopathy in general pediatric practice are commonly infections (bacterial or viral). Uncommon causes are immunological diseases such as Kawasaki syndrome and Kikuchi-Fujimoto disease. A progression of the lymph node swelling could lead to abscess. Methods We present a clinical case and a systematic literature research on PubMed was performed. Results A 9-year-old patient who developed a high fever 3 days apart with right cervical lymphadenitis and restricted neck mobility was reported to our hospital. The imaging revealed a lymphadenitis on the right side of the neck with increased inflammation parameters and negative blood cultures. Despite the intensive treatment, the patients condition was worsening and was transferred to a pediatric intensive care unit as an emergency, where a previous SARS- CoV- 2 infection was diagnosed as the cause of the symptoms and treated accordingly. Conclusions Patients infected from COVID-19 disease report commonly ENT symptoms as loss of smell and taste, nasal obstruction with rhinorrhea and a sore throat. Cervical lymphadenopathy was less common finding. Our research did not come across any description of unilateral lymphadenopathy as an initial symptom of a PIMS. The sonographic evaluation of the cervical lymph nodes is essential in the diagnosis of lymphadenitis colli and decisive for the indication of surgical procedures.
