Background: Elevated blood glucose concentration, also known as hyperglycemia, has been identified as a significant factor influencing the prognosis of COVID-19, alongside the impact of the SARS-CoV-2 infection itself., Methods: This research is a cross-sectional investigation that examined the relationship between COVID-19 and hyperglycemia in patients admitted to Afzalipour Hospital in Kerman, Iran, from July to September 2021. A standardized data sheet was used to capture demographic data (age, gender) and laboratory information (blood sugar, arterial blood oxygen saturation, and C-reactive protein (CRP)) upon admission., Results: The present research evaluated a total of 300 individuals diagnosed with COVID-19, with an average age of 50.19 ± 15.55 years. Among these patients, the majority were male, accounting for 51.67% of the total. Hyperglycemia was seen in 21.67% of patients, but less than 20% had new-onset diabetes. Individuals exhibiting hyperglycemia were typical of advanced age (P < 0.001). Furthermore, there was a slight but statistically significant association between advanced age and elevated blood glucose concentration (R = 0.254, P < 0.001). Gender had no significant impact on the occurrence of hyperglycemia (P = 0.199). There was no significant association between CRP levels and blood glucose concentration (P = 0.524) or the incidence of hyperglycemia (P = 0.473). Although there was no significant disparity in blood oxygen saturation between individuals with or without hyperglycemia (P = 0.06), higher blood glucose concentration was correlated with lower blood oxygen saturation (R = -0.151, P < 0.001)., Conclusion: Considering the correlation between blood glucose concentration, advanced age, and disease severity, it is recommended to carefully screen and monitor all COVID-19 patients for hyperglycemia and new-onset diabetes. Effective management of these complications could enhance the control of patients' overall prognosis and subsequent complications., (© 2024. The Author(s).)

Background: Infertility is defined as the failure to achieve pregnancy after one year of unprotected intercourse within a marital relationship. Approximately 10%-15% of couples worldwide experience infertility issues, with nearly half of these cases attributed to male factors. Among men with unexplained infertility, genetic mutations have been identified as a potential cause. Studies have indicated that mutations affecting the function of the protein encoded by the ACTL9 gene may play a role in male infertility., Methods: The purpose of this research was to identify mutations in the ACTL9 gene associated with male infertility in a sample of 40 infertile men with unknown causes. Genomic DNA extraction and PCR amplification were carried out on samples from each individual. The genetic material was then analyzed using Sanger sequencing, followed by bioinformatics and segregation analysis to determine the potential effects of the observed variations., Result: A novel genetic variant, c.376G>A (p.Glu126Lys), was identified in an infertile male individual, representing a previously unreported finding that was validated through segregation analyses. This specific variant induces a change from glutamate to lysine at the amino acid level by replacing the nucleotide G with A in the genomic DNA sequence, consequently impacting the secondary structure and function of the protein., Conclusions: The conclusive analysis of the procedure indicated that this alteration has the potential to interfere with the process of fertilization, ultimately resulting in the complete failure of fertilization (TFF) and causing male infertility., (© 2024 The Author(s).

Background: Predicting and finding the viral agents responsible for neonatal late-sepsis has always been challenging., Method: In this cross-sectional study, which has been done from September 2020 to December 2022, 145 hospitalized neonates suspected to late-onset sepsis alongside routine sepsis workup, were also evaluated for severe acute respiratory syndrome-coronavirus-2 (SARS-COV-2) infection, by nasopharyngeal real-time polymerase chain reaction (RT-PCR) or serological tests., Result: 145 neonates including 81 girls and 64 boys with a mean age of 12.3 ± 5.9 days and an average hospitalization stay of 23.1 ± 15.4 days were enrolled in the study. While 76.6% of them had negative bacterial culture, 63 patients (43.4%) showed evidence of SARS-COV-2 infection in RT-PCR or serology tests. None of the underlying factors including gender, age, and laboratory investigation had a significant relationship with SARS-COV-2 infection. Similarly, the outcomes of death and length of hospitalization were not different between the two groups with positive and negative SARS-COV-2 RT-PCR (P < 0.05). There was only a significant relationship between radiological changes including reticulonodular pattern, consolidation, pleural effusion, and different types of infiltrations and SARS-COV2 infection., Conclusion: Considering the widespread of coronavirus disease 2019 (COVID-19) in newborns, it seems logical to investigate the SARS-COV-2 infection in late-sepsis., (© 2024.

Background: In April 2020, an association between multisystem inflammatory syndromes (MIS-C) was observed in children with severe acute respiratory syndrome coronavirus infection (SARS-CoV-2). Most patients had heart involvement alone, and most patients had pericardial effusion. This study aimed to express and emphasize cardiac involvement in pediatric patients with respiratory symptoms who were diagnosed with COVID-19., Methods: This study was conducted in July 2021 in Kerman province, Southeastern Iran, during a notable surge in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. The study included 904 pediatric patients diagnosed with COVID-19. Data collection involved a comprehensive assessment of clinical symptoms and manifestations. Patients with fever lasting more than five days were admitted to the hospital. Echocardiography was utilized for cardiac involvement diagnosis, with 47 patients undergoing this diagnostic procedure., Results: Of the 904 patients, most of them had high fevers (74%). Fifty-five patients had a fever for more than five days and were hospitalized. Of the 47 patients who underwent echocardiography, 45 (81%) had heart involvement. In 75% of patients, pericardial effusion was the only cardiac involvement. Patients with pericardial effusion were treated with dexamethasone up to 3 mg every 8 h for 72 h., Conclusions: MIS-C has a wide range of clinical symptoms. In cases where the fever is prolonged and there are gastrointestinal symptoms, physicians have clinical suspicion to diagnose this syndrome. Most cases of pericardial effusion are alone and improve with treatment with glucocorticosteroids., (© 2024. The Author(s).)

Background: Renal involvement is the most damaging long-term complication of Immunoglobulin-A (IgA) vasculitis. In the lack of a definite predictive biomarker for renal involvement, antiphospholipid antibodies (aPL) have been proposed in recent years., Methods: In this prospective cohort of 48 pediatric patients who were admitted with IgA vasculitis from September 2015 to June 2017, two serum samples were taken 12 weeks apart to detect Anti-Phospholipid antibodies. All patients were followed-up for renal involvement for six months., Results: Renal involvement occurred in 14 out of 48 patients with IgA vasculitis (29.16%). APLs were positive in nine out of 14 patients with IgA vasculitis and renal involvement (64.28%), in contrast to only six out of 34 patients with IgA vasculitis without renal involvement (17.64%). The presence of aPL antibodies was statistically associated with renal involvement (P=0.002). Although, the relationship between both sex (P=0.025) and age (P=0.046) with aPL positivity was statistically significant, performing a modified logistic regression test, the odds ratio was significant between the groups with and without renal involvement only in term of age and aPL positivity)., Conclusion: The presence of aPL antibodies was statistically associated with renal involvement. We found a significant relationship between the age and aPL positivity. Hence, we need multicenter, more extensive cohort studies to reach a better and more accurate conclusion on the relationship between serum aPLs and renal involvement in IgA vasculitis patients., Competing Interests: The authors report no conflicts of interest regarding this manuscript. None of the authors, nor their institutions, received any payment or services from a third party for any aspect of the submitted work., (© The Author(s).)

Background: Empyema as a rare cause of respiratory distress in neonatal period has not yet been reported after Corona virus disease 2019 (COVID-19) and even rarely in the context of bacterial infections is age group., Case Presentation: The first neonate of quadruplets, resulting from Cesarean-Section of a 30-year-old mother without a history of previous illness, born at 34 weeks of gestation with a birth weight of 1600 gram. All four newborns were hospitalized; while the first one underwent nasal continuous positive airway pressure (N-CPAP) with a positive end-expiratory pressure of 6 and fractional inspired oxygen of 0.6, due to respiratory distress, noting a respiratory score of five out of 12.She was resuscitated one hour later due to bradycardia and underwent ventilator support. She received a single dose of pulmonary surfactant, intravenous paracetamol, and phenobarbital due to respiratory distress syndrome, Pectus Ductus Arteriosus, and unilateral clonic movements, respectively. In the lack of positive blood culture, she extubated two days later and breast-feeding was started. On day eight, she underwent high flow nasal cannula. On day 12, she suddenly developed respiratory distress, mottling, and abdominal distension, leading to N-CPAP and re-evaluation. The nasopharyngeal sampling for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) real time Polymerase chain reaction and the blood culture for staphylococcus aurous became positive. A large volume pleural effusion including septa and loculation in right hemi-thorax on chest computerized tomography scan and ultrasound was seen, necessitating to thoracotomy, which was not possible due to her general condition. Remdesivir was started and antibiotics changed to a more broad-spectrum coverage. Chest tube was inserted and Alteplase was injected for three consecutive days with beneficial effects. She had no problem for six-month follow up., Conclusion: This was a case of empyema thoracic in the context of SARS-CoV-2 and Staphylococcus arouses co-infection. In our experience, it can be treated by chest drainage and fibrinolysis in neonatal period., (© 2023. The Author(s).)

Background: H-type Tracheoesophageal Fistula (TEF) is a particular type of congenital esophageal anomalies, in which patients present with non-specific symptoms that can result in delayed diagnosis. Here, we report two pediatric cases with a rarer variant called ‟dual H-type TEFˮ., Case Presentation: We present two cases of H-type TEF. The first was a 45-day-old boy with feeding problem and cyanosis while feeding, and the second was a three-month-old girl with cough and choking after feeding from the first day of birth. In both cases, two separate TEFs were detected during diagnostic evaluation by flexible bronchoscopy. Both were repaired simultaneously through a cervical incision. The first patient deteriorated 13 days after the surgery, disturbancing in acid-base balance and expired unfortunately., Conclusion: Hence, it is necessary to consider the possibility of double TEF in any newly diagnosed H-type TEF., (© 2023.

COVID-19-associated acute transverse myelitis (ATM) cases have been reported worldwide. Nevertheless, Iran, Italy, and the USA are the most affected countries, witnessing the possibility that genetic factors might be associated with this susceptibility. The genetic variants of the coronavirus-2 entry mechanisms and host innate immune response-related genes like interferons, interleukins, Toll-like receptors, human leukocyte antigens, blood groups, and some risk loci may be accountable. This study describes the compatibility of the geographical distribution between ATM and the Neanderthal core haplotype that confers risk for severe COVID-19 and some possible culprit genes., Competing Interests: The authors declared no conflict of interest.

Background: There is growing evidence of nervous system involvement and related complaints in children with coronavirus disease 2019 (COVID-19). However, it seems that attempts to track of the virus in the nervous system have so far been unsuccessful., Case Presentation: Here we describe two pediatric cases of severe COVID-19 who had positive cerebrospinal fluid (CSF) and nasopharyngeal polymerase chain reaction (PCR) tests for severe acute respiratory syndrome coronavirus disease 2019 (SARS-CoV-2). A 36-month-old girl who presented with fever, diarrhea, mild left ventricular dysfunction and bizarre movements, and a five-month-old boy who presented with fever, watery diarrhea, severe dehydration, mottling, and two episodes of seizure. Their CSF analyses and cultures were normal. They admitted in intensive care unit (ICU) for near four days and discharged after ten days without any complaint., Conclusion: This is one of the first reports of the presence of coronavirus in the central nervous system in COVID-19 pediatric patients, emphasizing the neurotropism and neuroinvasion characteristics of the virus., (© 2023.

Background: Neonatal phototherapy (NNPT) has long been used as an effective and relatively safe method of treating neonatal hyperbilirubinemia. Considering the subsequent evidence of long-term impacts of NNPT such as malignancies, this study was conducted to evaluate the relationship between NNPT and childhood cancers., Methods: This case-control study assessed 116 children up to 4 years old with every kind of cancer referred to the Oncology department of Afzalipour hospital, Kerman, Iran, from 2011 to 18. Moreover, 116 pediatric patients without cancer hospitalized at the same Center were included after sex and age matching as the control group. The history of phototherapy and its duration were evaluated in these two groups., Results: We found no association between the NNPT and malignancies in children. However, high intensive phototherapy was higher historically among affected cancerous patients than in non-cancerous cases without any statistically significant difference (25% vs 19%; P = 0.26). Maternal educational level and history of maternal infection during pregnancy, which initially appeared to be two factors associated with malignancy in single variable regression analyses, were not significant based on the adjusted models., Conclusions: The results did not show a positive correlation between NNPT and childhood cancers, which may partly be due to the relatively small sample size of the study. However, some other evidence is worrisome enough that NNPT should not be considered risk-free. Additional multi-centric studies should be undertaken to specify that phototherapy is really safe., (© 2022. The Author(s).)

Background: Despite the relative prevalence of small bowel and proximal colon perforation in the neonatal period, recto-sigmoid perforation is extremely rare. Full-term neonates experience intestinal perforation less frequently than premature infants. Here we report a neonate with sigmoid perforation and simultaneous Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection., Case Presentation: A 2550 g female neonate born at 38-weeks' gestation from a coronavirus disease-2019 (COVID-19) infected mother by cesarean section. Despite a good Apgar score in the first and fifth minutes, she was admitted to the neonatal intensive care unit with grunting and mild respiratory distress. She underwent antibiotics and oxygen by head box resulting in an Oxygen Saturation rate of 94%. The patients' respiratory distress decreased during the second day, resulting once breastfeeding without tolerance. While she passed meconium in the first 2 days, she developed abdominal distention on day 3. The nasopharyngeal SARS-CoV-2 real-time polymerase chain reaction (RT-PCR) was performed with positive results. Surgical consultation was requested and a thoraco-abdominal X-Ray was performed at this stage, which suspected to be a gastrointestinal perforation. Due to clinical deterioration and persistent abdominal distention, a contrast study was performed with water-soluble contrast, which confirmed intestinal perforation. However, the surgical exploration revealed perforation of the sigmoid colon at the posterior segment. The patient underwent antibiotic therapy, abdominal lavage, and colostomy, immediately. She was discharged in good condition approximately 14-days later., Conclusion: To our knowledge, this is the first report of sigmoid colon perforation in a term neonate following COVID-19., (© 2022.

The global coronavirus disease 2019 (COVID-19) pandemic appears to have some streaks of severity in pediatrics. These streaks include variable signs of respiratory distress, a new entity called multi-system inflammatory syndrome, and some evidences of neurological symptoms involving both central and peripheral nervous systems. Here, we described the first pediatric patient with COVID-19 who presented with acute transverse myelitis. An 11-year-old otherwise healthy girl presented to our clinic with acute onset of lower limbs paresis, urinary and fecal retention, alongside epigastric pain, and fever for 3 days. A neurological examination revealed a severe flaccid paraplegia in her lower limbs associated with a sensory level at T5. She was evaluated systematically for all probable causes of her symptoms, and finally, due to having a positive nasopharyngeal PCR test, she was considered to suffer from post-COVID-19 transverse myelitis. She underwent intravenous-immunoglobulin, methylprednisolone pulse, and other supportive cares without obvious results. Therefore, she underwent seven sessions of plasma exchange with little effects on muscle strength. The focal inflammation and injury of the spinal cord, otherwise known as transverse myelitis, have a wide array of potential etiologies. Transverse myelitis has been well documented to be the result of viral and bacterial infections. We believe our patient was not involved in a cytokine storm status due to good CRP, IL-6 and Ferritin levels. Albeit, we cannot certainly consider the patient to have a direct viral impactor involved in a late immunity process. To our knowledge, this is the first report of TM in the field of pediatrics occurred after COVID-19. Thus, this is critical to note that children can present with some severe types of COVID-19., Competing Interests: None declared

Background: Although, preliminary reports of Severe Acute Respiratory Syndrome (SARS)-CoV-2 infection suggest that the infection causes a less severe illness in children, there is now growing evidence of other rare or even serious complications of disease., Case Presentation: During the recent COVID-19 pandemic in Kerman, Iran, two children (an 8 year-old boy and a 6 year-old girl) were referred to outpatient Clinic of Pediatric Rheumatology with complaints of limping. Both children had experienced fever and mild respiratory tract infection. At the beginning of the second week of infection, they developed joint effusion. They both tested positive for coronavirus infection and were therefore diagnosed with post Coronavirus reactive arthritis. Both children were treated successfully with rest and Non-Steroidal Anti-Inflammatory Drugs (NSAID). They did not have any medical problems in the two months fallow up., Conclusions: These two cases suggest that COVID-19 may be rheumatogenic. Highlighting the need for awareness of physicians, especially pediatricians, regarding the pathogenesis margins of this virus, as late presentations are of great importance.

Juvenile dermatomyositis (JDM) is a rare idiopathic inflammatory disease, which usually presents with skin rashes along with muscle weakness. We report a case of JDM in a 10- year-old girl with no skin manifestations presenting with progressive muscle weakness and fatigue. Further laboratory investigations, along with a muscle biopsy, confirmed the diagnosis of adermatopathic JDM. The patient was treated with intravenous immunoglobulin, corticosteroids, methotrexate, hydroxychloroquine, pamidronate, and rituximab. Following treatment, patients' symptoms subsided, and she gained normal muscular strength over a year.

Background: The current diagnostic cornerstone for septic arthritis contains gram stains, bacterial culture, and cell count with a differential of aspirated synovial fluid. Recently, a synovial leukocyte esterase (LE) test has been used for diagnosing septic arthritis. Since this test measures the esterase activity of leukocytes, there is always a dilemma for using this test in patients with inflammatory arthritis., Methods: We collected the synovial fluid specimens as part of the general diagnostic protocol for patients suspected of Juvenile Idiopathic Arthritis (JIA) or Septic Arthritis (SA). Each group included 34 patients. We compared the result of the synovial LE test with the result of the culture of each patient., Results: The mean ages of patients were 64.14 ± 31.27 and 50.88 ± 23.19 months in the JIA group and septic arthritis group, respectively. The LE test results were positive in 30 specimens, trace in 3 and negative in one in the first-time test and were positive in 31 specimens and trace in 3 in the second-time test, while it was negative in all patients with JIA. Hence, the sensitivity of the synovial LE test was 80.8%, the specificity, PPV, and NPV were 78.6, 70.0, 86.8% respectively based on a positive culture., Conclusion: The leukocyte esterase strip test can be used as a rapid, bedside method for diagnosing or excluding bacterial infections in different body fluids. The synovial LE test can be used as an accurate test to rapidly rule in or out an acute articular bacterial infection, even in patients with concurrent inflammatory arthritis.
