RESUMEN
Background: Spontaneous bacterial peritonitis (SBP) is a fatal complication of ascites fluid infection. The causes of SBP in children differ from those in adults, and these bacteria are frequently resistant to antibiotics. Therefore, this study investigated the clinical findings, bacterial etiology, and antimicrobial resistance in children with SBP. Methods: This study was conducted on all new pediatric ascites patients, who were admitted to the Department of Pediatric Gastroenterology, Namazi Hospital, affiliated with Shiraz University of Medical Sciences (Shiraz, Iran) from 2021 to 2022. Required data such as demographic information, and clinical information such as complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Gram staining, blood culture by Automated Blood Culture System (BACTEC), and antibiogram of ascites fluids by disc diffusion method were all collected. Finally, the data were statistically analyzed using SPSS Software (version 26). Besides, the t test, Fisher's exact, Mann-Whitney, and Chi square tests were used for data analysis. In all tests, P≤0.05 was considered statistically significant. Results: The present study examined 62 children with ascites of which 18 (29%) had SBP. The median (IQR) age was 2.5 (8.1) years. Thirty-four (54.8%) of the participants were girls. Abdominal pain was the most common clinical manifestation in patients (54%), and there was a significant association between abdominal pain and SBP (P=0.02). In 12 positive ascites fluid cultures, coagulase-negative staphylococci had the highest frequency (25%), followed by Escherichia coli (16.7%). Third-generation cephalosporins had a 25% sensitivity in the total positive cultures. This sensitivity was 33.3% for Gram-negative cultures and 16.6% for Gram-positive cultures. Conclusion: Although third-generation cephalosporins are recommended as the primary antibiotic for the empirical treatment of SBP, the present study found high bacterial resistance. Finally, empirical therapy should be tailored to each region's bacterial resistance features.

Background: There have been few studies on the effect of Kegel exercises on the treatment of functional constipation in children. Hence, the present study investigated the add-on role of Kegel exercises in children with functional constipation. Methods: This clinical trial was conducted on children with functional constipation, according to Rome IV, who were referred to the pediatric department of Imam Reza Clinic (Shiraz, Iran) in 2022. The sample consisted of 64 children who were randomly assigned to either the intervention or the control groups. In the control group, a pediatrician administered conventional therapy, including diet training, defecation training, and polyethylene glycol (PEG) syrup (0.7 g/Kg daily). In the treatment group, in addition to conventional therapy, a pediatrician taught Kegel exercises to the child both verbally and in writing in the presence of their parents. To investigate the effectiveness of the intervention, frequency of defecation, defecation time, assistance used for defecation, incomplete emptying, unsuccessful defecation, abdominal pain, and painful defecation were selected as the outcomes. Independent sample t test was used for continuous variables. Categorical variables were reported as frequency and percentages. To examine the difference in categorical outcome variables, Wilcoxon (pre and post), Chi square, and Fisher exact tests were used. Data were analyzed using SPSS software version 21. P<0.05 were considered statistically significant. Results: Twenty-seven (88.4%) patients in the Kegel exercise group reported a defecation time of less than 5 min, while only 12 (37.5%) patients in the control group reached this time, and this difference was statistically significant (P=0.001). Moreover, patients in the treatment group showed significant improvements in terms of incomplete emptying of stool, unsuccessful defecation, abdominal pain, and painless defecation (P=0.001, P=0.001, P=0.001, P=0.037, respectively). After intervention, the use of laxatives, digits, or enemas to assist defecation was not significantly different between the groups (P=0.659). Conclusion: Kegel exercise was an effective adjunctive treatment for pediatric functional constipation.Trial Registration Number: IRCT20230424057984N1.

Background: Large-volume paracentesis has become the first treatment choice for patients with severe and refractory ascites. The studies have reported several complications after therapeutic paracentesis. But there are few published data on the complications with or without Albumin therapy. We aimed to analyze the safety and complications of large-volume paracentesis in children with or without albumin therapy. Methods: This study was conducted on children with severe ascites with chronic liver disease who underwent large-volume paracentesis. They were divided into albumin-infused and albumin non-infused groups. In the case of coagulopathy, no adjustment was made. Albumin was not administered after the procedure. The outcomes were monitored to evaluate the complications. To compare two groups, a t-test was utilized, and the ANOVA test was used to compare several groups. If the requirements for using these tests were not met, Mann-Whitney and Kruskal-Wallis tests were applied. Results: Decreased heart rate was observed in all time intervals and was meaningful six days after paracentesis. MAP also decreased statistically at 48 hours and six days after the procedure (P < 0.05). Other variables did not show any meaningful change. Conclusion: Children having tense ascites with thrombocytopenia, prolonged PT, Child-Pugh class C, and encephalopathy can undergo large-volume paracentesis without any complication. Albumin administration before the procedure in patients with low levels of Albumin (<2.9) can effectively overcome the problems of tachycardia and increased mean arterial pressure. There will be no need for Albumin administration after paracentesis.
RESUMEN
Background: Large-volume paracentesis is the preferred treatment for patients with severe and refractory ascites. Several complications were reported during therapeutical paracentesis. However, there are very few published studies on the change in blood cell count after paracentesis. This study aimed to evaluate any changes in blood cell counts after ascites fluid drainage. Methods: This study was conducted on patients with severe ascites and chronic liver disease who underwent large-volume paracentesis at Namazi Hospital, in Shiraz, Iran, between March 2021 and February 2022. A data gathering form containing the patient's medical history, cause of cirrhosis, ascites fluid volume, as well as routine tests including primarily sodium, potassium, and basal creatinine, was filled out. Before and after the surgery, the total blood cell count was measured. Before the procedure, adjustment was made in the case of coagulopathy and albumin deficiency. The effect of factors such as the volume of drained fluid, splenomegaly, antibiotics, and steroid use was assessed on the changes in the number of blood cells. Using the JAMOVI 2.3.9 software, a paired t test and multiple regression were applied for statistical analysis (P<0.001). Results: The study included 37 patients. After the paracentesis procedure, the number of blood cells significantly decreased in all groups (P<0.001). The followings are the amounts of each type of blood cells before and after the procedure: Platelet=153837±91862 and 115648±69136, red blood cells=3.53±0.784 and 3.22±0.705, white blood cells=12.3±7.78 and 8.6±5.5. None of the study variables, including drained volume, splenomegaly, antibiotics, and steroid use, were significant predictors of the changes in the blood cell count after paracentesis (P>0.001). Conclusion: The findings of the present study showed that children with tense ascites who had large-volume paracentesis might experience a sharp drop in blood cell count after the procedure, which was a transient physiological condition.

OBJECTIVES: Hereditary fructose intolerance (HFI) is caused by aldolase B enzyme deficiency. There has been no report about HFI from Iran and the type of mutations has not been reported in the Iranian population so far. CASE PRESENTATION: Herein we report a 2 year old girl presented with failure to thrive, hepatomegaly, and liver dysfunction. The primary impression has been hepatic glycogen storage disease type 1 or 6. This diagnosis was not confirmed by laboratory data and liver biopsy. Therefore, targeted-gene sequencing (TGS) covering 450 genes involved in inborn errors in metabolic diseases was performed. The results of TGS showed a rare novel homozygous pathogenic variant c.944del (p.Gly315ValfsTer15) in the ALDOB gene. CONCLUSIONS: This report introduces a novel variant that expands the mutational spectrum of the ALDOB gene in patients with HFI.

Background & Objective: The TSH reference range's validity affects the thyroid dysfunction diagnosis. The primary objective of this study is to determine the reference range, which is established according to age and region. Methods: The data were collected retrospectively from people over the age of one who visited Motahari Clinic for routine health checkups between August 2017 and October 2019. TSH, T4, T3, personal drug usage, and thyroid history were collected. After excluding subjects with thyroid diseases and outliers, 1392 participants were analyzed. Hormone intervals of men and women ≥1 year old have been determined using the non-parametric method. Results: The non-disease subjects' TSH, T3, and T4 reference ranges were 0.64 to 5.94 lU/mL, 0.91 to 2.47 ng/dL, and 5.53 to 12.48 g/dL, respectively. According to this range, total thyroid dysfunction prevalence in our study in children was 8.94%. There was no significant difference between TSH, T4 level, and gender in the non-disease population (P=0.46 and 0.13, respectively), but there was a statistical difference between sex and T3 (P =0.03). Our study also illustrates that for subjects under 18 years old and older, the hormones (TSH, T3, T4) concentration are statistically different (P≤0.001). Conclusion: We found a statistically difference between hormone values younger and older than age 18 (P=≤0.01); therefore, it is not appropriate to use the same reference range for children younger than age 18 and adults. There was male predominance in the population aged1-18 years old.
RESUMEN
BACKGROUND: Leeches are a class of hermaphroditic parasites that can attach to various body parts and start sucking blood. Gastrointestinal (GI) bleeding due to leeches is a rare phenomenon that is more common in less developed countries. Common symptoms include melena, hematemesis, pallor, weakness, and fatigue. Due to the similar symptoms of this issue to the main differential diagnoses of GI bleeding in pediatrics, such as diarrhea, constipation, diverticulitis, esophagitis, and anal fissures, it is challenging to differentiate it from the rest. CASE PRESENTATION: We present a three-year-old boy who was transferred to our center with hematemesis, tarry stool, and a drop in hemoglobin level. He finally was diagnosed with a leech in his stomach. CONCLUSIONS: In less developed counties, the inability to reach safe drinking water, swim in lakes or springs, and inadequate awareness of public health information among individuals can be risk factors for leech infestation.

Patient variants in Tubby Like Protein-3 (TULP3) have recently been associated with progressive fibrocystic disease in tissues and organs. TULP3 is a ciliary trafficking protein that links membrane-associated proteins to the intraflagellar transport complex A. In mice, mutations in Tulp3 drive phenotypes consistent with ciliary dysfunction which include renal cystic disease, as part of a ciliopathic spectrum. Here we report two sisters from consanguineous parents with fibrocystic renal and hepatic disease harboring a homozygous missense mutation in TULP3 (NM_003324.5: c.1144C>T, p.Arg382Trp). The R382W patient mutation resides within the C-terminal Tubby domain, a conserved domain required for TULP3 to associate with phosphoinositides. We show that inner medullary collecting duct-3 cells expressing the TULP3 R382W patient variant have a severely reduced ability to localize the membrane-associated proteins ARL13b, INPP5E, and GPR161 to the cilium, consistent with a loss of TULP3 function. These studies establish Arginine 382 as a critical residue in the Tubby domain, which is essential for TULP3-mediated protein trafficking within the cilium, and expand the phenotypic spectrum known to result from recessive deleterious mutations in TULP3.
RESUMEN
The esophagus is the gastrointestinal tract's primary organ that transfers bolus into the stomach with peristaltic motion. Therefore, its lesions cause a significant disturbance in the nutrition and digestive system. Esophageal disease treatment sometimes requires surgical procedures that involve removal and circumferential full-thickness replacement. Unlike other organs, the esophagus has a limited regeneration ability and cannot be transplanted from donors. There are various methods of restoring the esophageal continuity; however, they are associated with certain flaws that lead to a non-functional recovery. As an exponentially growing science, tissue engineering has become a leading technique for the development of tissue replacement to repair damaged esophageal segments. Scaffold plays a significant role in the process of tissue engineering, as it acts as a template for the regeneration of growing tissue. A variety of scaffolds have been studied to replace the esophagus. Due to the many tissue quality challenges, the results are still inadequate and need to be improved. The success of esophageal tissue regeneration will finally depend on the scaffold's capability to mimic natural tissue properties and provide a qualified environment for regeneration. Thereby, scaffold fabrication techniques are fundamental. This article reviews the recent developments in esophageal tissue engineering for the treatment of circumferential lesions based on scaffold biomaterial engineering approaches.

ETHNOPHARMACOLOGICAL RELEVANCE: Rosa × damascena Herrm., known as damask rose, is a bushy shrub that is found abundantly in Fars province, Iran. This species has been used in Iranian traditional practices for the treatment of abdominal pain and constipation, as gastrointestinal diseases. Brown sugar (Saccharum officinarum L.) has also shown laxative effects in pediatric patients with functional constipation. AIM OF STUDY: This study aimed to compare the effects of Polyethylene Glycol (PEG) and a syrup made of R. damascena and brown sugar on the treatment of functional constipation in children aged above 12 months. MATERIALS AND METHODS: This double-blind randomized clinical trial was performed on 100 patients. One group received PEG and the other received an herbal syrup containing the decocted extract of 0.1 g R. damascena petals mixed with 0.85 g brown sugar per 1 mL. The patients were followed up for two and four weeks and their progresses were recorded. RESULTS: The cure rate was 100% in the R. damascena group and 91.7% in the control group. R. damascena and brown sugar syrup had an odds ratio of 1.09 in the treatment of functional constipation compared to PEG, but the difference was not statistically significant. The only adverse effect detected in the R. damascena group after four weeks was the bad taste of the medication that was too sweet. Nonetheless, this could be solved during the pharmaceutical processes. CONCLUSION: The R. damascena extract and brown sugar syrup can be used as an effective, safe, and inexpensive agent in the treatment of functional constipation.

BACKGROUND: The most common infection in children with the hepatic disease with or without cirrhotic ascites is spontaneous bacterial peritonitis (SBP), which occurs in the absence of an evident intra-abdominal source of infection. The present study aims to assess the value of calprotectin in ascitic fluid in the diagnosis of ascitic fluid infection in children with liver cirrhosis. MATERIALS AND METHODS: In this cross-section study, 80 children with underlying liver disease who attended the Hepatology and Emergency Department in Shiraz University Hospitals were studied. All the patients were evaluated by a thorough history, clinical examination, laboratory investigations, diagnostic paracentesis with PMNLs count, and Calprotectin, which was measured in 1 mL ascitic fluid by ELISA. RESULTS: Thirty-five patients (43.75%) were diagnosed with ascitic fluid infection. Of these children 6 cases had positive ascitic fluid culture (SBP). Calprotectin was high in AFI patients with a statistically significant difference in AFI patients compared to non-AFI patients. The cut-off levels were 91.55 mg /L and the area under the curve was 0.971. So it can serve as a sensitive and specific diagnostic test for detection of AFI in children with underlying liver disease. CONCLUSION: Elevated ascitic calprotectin levels in cirrhotic patients are a diagnostic and reliable marker for the detection of AFI and are considered a surrogate marker for PMN.

BACKGROUND: One of the most severe side effects of solid-organ transplantation is posttransplant lymphoproliferative disease (PTLD). People with human immunodeficiency virus infection (HIV), an immunosuppressive disease comparable to HIV, have a higher chance of developing lymphoma when their peripheral blood contains elevated levels of the immunoglobulins kappa and lambda free light chains (FLCs). METHODS: This systematic review's objective was to monitor associated B lymphoma cells in PTLD patients. In order to find relevant studies published between 1/1/2000 and 1/9/2022, two independent researchers conducted searches (MT, AJ). A literature search of English language publications was conducted using MEDLINE through PubMed, EMBASETM through Ovid, the Cochrane Library, and Trip. In addition to Magiran and SID, we searched KoreaMed and LILACS for literature published in other languages. sFLC or PTLD, transplant, or Electrophoresis are terms used in the search strategy. RESULTS: A total of 174 studies were selected. After analyzing their correspondence with the required criteria, a final review of five studies was conducted. The manuscript presents current findings on the potential benefits of the clinical applicability of sFLCs in PTLD. While the preliminary results appear promising, the only consistent result is that early-onset PTLD is predicted within the first two years after transplant, a biomarker that could be used to diagnose the condition. CONCLUSIONS: Therefore, PTLD has been predicted by using the sFLCs. There have been contradictory results to date. Future research could include assessing the quantity of sFLCs and their quality in transplant recipients. In addition to PTLD and complications after transplantation, sFLCs may provide insight into other diseases. To confirm the validity of sFLCs, more studies are needed.

OBJECTIVES: Glycogen storage diseases (GSDs) are heterogeneous disorders caused by various enzyme deficiencies. GSD type IX α2, the most common subtype of GSD IX, is due to a deficiency of hepatic phosphorylase kinase. Herein we will report a novel mutation in this disease with an unusual presentation. CASE PRESENTATION: we describe a 3-year-old boy who suffered from hepatomegaly, fatty liver disease, and liver cirrhosis. The cause of cirrhosis at a young age was unknown based on the laboratory data and liver biopsy, so we performed a targeted-gene sequencing (TGS) covering 450 genes involved in inborn metabolic diseases consisting of glycogen storage disorders genes with hepatic involvement. He was found out to have a rare novel pathogenic variant in the PHKA2 gene. CONCLUSIONS: This novel variant c.2226+2T > C expands the mutational spectrum of the PHKA2 gene. Also, severe liver damage (cirrhosis) in patients with GSD- IX α2 has rarely been reported, which needs further discussion. We hypothesize that unidentified PHKA2 variants may be a rare cause of childhood liver cirrhosis.

BACKGROUND Celiac disease is a common disorder but there are few studies comparing the clinical features of the disease in adults, adolescents and children. METHODS Demographic and clinical characteristics of all patients with celiac disease referred to the Celiac Clinic were evaluated and compared in different age groups. RESULTS Of 3416 participants, 473 patients were included. 302 (63.8%) were women and 171 (36.2%) were men. Overall, 325 (68.7%) and 411 (86.9%) patients had gastrointestinal (GI) and non-GI manifestations, respectively. The most common symptom in adults was psychiatric problems (66.5%), while abdominal discomfort was the most common symptom in adolescents (45.2%) and children (53.8%). According to age groups, GI manifestations were seen in 79 (66.4%), 119 (59.8%), and 127 (81.9%) children, adolescents, and adults, respectively. Adults had significantly more GI manifestations than the other groups (PR 1.167; 95% CI: 1.094- 1.244; p < 0.001). Non-GI manifestations were seen in 90 (75.6%), 174 (87.4%), and 147 (94.8%) children, adolescents, and adults, respectively. Adults had significantly more non-GI manifestations than the other groups (PR 1.112; 95% CI: 1.060-1.168; p < 0.001). CONCLUSION Our study showed that there were significant differences in the clinical features of celiac disease between the different age groups. Considering these results may help plan for future studies.
RESUMEN
BACKGROUND: We aimed to evaluate the impact of COVID-19 pandemic on pediatric transplant outcomes and determine whether to continue pediatric transplant activity or not, and how policies intended our center has been effective in preventing COVID-19 among organ transplant recipients. METHODS: We conducted a single-center, retrospective, cohort study of hospitalized pediatrics after organ transplantation at Shiraz transplant center since March to August 2020. All liver and kidney transplanted children were included the study and their laboratory and clinical related COVID-19 characteristics were followed up till 3 months after transplantation during hospitalization period and then weekly by the transplant committee. RESULTS: Fifty-one patients underwent transplantation including 11 kidney and 40 liver recipients. The mean age of the pediatric cases was 6.72 ± 5.47 years. A total of 11 patients died due to post-transplant complications, while none of the patients presented any sign or symptoms in favor of COVID-19 in the hospital course after transplantation. Six transplants including 2 kidney and 4 liver were canceled when positive PCR tests were detected in their donors before the surgery. In the 3 months of follow up, two patients presented with symptoms including high grade fever, malaise, rhinorrhea, and GI symptoms. Both patients had two negative PCR, and no radiologic or laboratory results regarding COVID-19 were also detected. One had positive influenza PCR, while the second one had a positive serologic test for EBV; CT, computed tomography CONCLUSION: Transplant programs could continue their activities during the COVID-19 pandemic with specific case selection, accurate screening methods and following protective protocols.

Glycogen storage diseases (GSDs) are known as complex disorders with overlapping manifestations. These features also preclude a specific clinical diagnosis, requiring more accurate paraclinical tests. To evaluate the patients with particular diagnosis features characterizing GSD, an observational retrospective case study was designed by performing a targeted gene sequencing (TGS) for accurate subtyping. A total of the 15 pediatric patients were admitted to our hospital and referred for molecular genetic testing using TGS. Eight genes namely SLC37A4, AGL, GBE1, PYGL, PHKB, PGAM2, and PRKAG2 were detected to be responsible for the onset of the clinical symptoms. A total number of 15 variants were identified i.e. mostly loss-of-function (LoF) variants, of which 10 variants were novel. Finally, diagnosis of GSD types Ib, III, IV, VI, IXb, IXc, X, and GSD of the heart, lethal congenital was made in 13 out of the 14 patients. Notably, GSD-IX and GSD of the heart-lethal congenital (i.e. PRKAG2 deficiency) patients have been reported in Iran for the first time which shown the development of liver cirrhosis with novel variants. These results showed that TGS, in combination with clinical, biochemical, and pathological hallmarks, could provide accurate and high-throughput results for diagnosing and sub-typing GSD and related diseases.

BACKGROUND: Motorcycle drivers are among the most vulnerable road users, accounting for a large proportion of global traffic accidents. This study aimed to investigate the association between the score of adult attention-deficit/hyperactivity (ADHD) traits and risky driving behaviors (RDB) with alcohol intake (AI) and narcotics consumption (NC) among motorcyclists in Iran. METHODS: This multi-center cross-sectional study encompassed 1747 motorcyclists from three cities in Iran. A random sampling method was applied in this study, and the required data was collected using three standard questionnaires on ADHD, substance abuse, and RDB. Independent sample t-test, covariance analysis, and quantile regression (QR) were used to analyze the data. RESULTS: The results of t-test and analysis of covariance indicated that AI and NC were significantly associated with ADHD score and RDB among the motorcycle drivers. Additionally, the QR models showed that these effects were significant at all quantiles of ADHD and RDB, even for individuals who were at lower quantiles. CONCLUSIONS: Considering the potential dangers of driving after AI and NC, appropriate measures should be adopted before certifying a driving license to screen ADHD as a predisposing factor for substance abuse and RDB. Furthermore, it is essential to equip traffic police with adequate diagnosis kits and establish heavy penalties for the offenders. In this regard, all interventions aimed to reduce traffic accidents among motorcycle drivers should be done considering the interrelationship between ADHD, RDB, and substance abuse.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide. One treatment is the use of metformin but its efficacy remains to be established. OBJECTIVE: The present systematic review and meta-analysis aimed to provide a more robust examination of the evidence for the effectiveness of metformin for treating non-diabetic NAFLD patients. METHODS: An extensive literature search was undertaken using online databases (PubMed, Embase, Scopus, Web of Science and Cochrane Library) to detect randomized controlled trials (RCTs) investigating the effect of metformin administration on liver enzymes and body composition in non-diabetic NAFLD patients up to 10 December 2019. A random-effects or fixed-effect models were performed to pool weighted mean difference (WMD) and 95% confidence intervals (CI). RESULTS: Six RCTs involving 307 individuals were included to the present meta-analysis. Compared to controls, metformin significantly reduced body mass index (BMI) (WMD: -0.77 kg/m2, 95 % CI = [-1.46, -0.07], P = 0.03, I2 = 0.0 %) and serum aspartate aminotransferase (AST) (WMD: -5.94 U/L, 95 % CI = [-11.51, -0.38], P = 0.03, I2 = 67.6 %). Also, body weight (WMD: -2.70 kg, 95 % CI = [-5.49, 0.09], P = 0.05, I2 = 33.7%) was marginally significant and serum alanine transaminase (ALT) (WMD: -5.04 U/L, 95 % CI = [-13.92, 3.84], P = 0.26, I2 = 60.9 %) was not statistically significant affected by metformin administration. There was no evidence of publication bias. CONCLUSION: In summary, the present study emphasizes the clinical importance of metformin administration for improving liver function and body composition in non-diabetic NAFLD patients. Moreover, the further large-scale and well-designed RCTs are required to confirm these findings.
