RESUMEN
Congenital abdominal adhesions are a rare condition that can result in a small bowel obstruction at any age, more frequently in pediatric populations. The cause remains unknown, and the importance of aberrant congenital bands is related to the difficulty of diagnosis, and cases of death with late detection have been documented. This research examines the expression of Caudal Type Homeobox 1 (CDX1), Indian Hedgehog (IHH), Sonic Hedgehog (SHH), GATA Binding Protein 4 (GATA4), Forkhead Box A2 (FOXA2) and Forkhead Box F1 (FOXF1) gene expression in human abdominal congenital adhesion fibroblast and endothelium cells by chromogenic in situ hybridization, with the aim of elucidating their potential association with the etiology of congenital intra-abdominal adhesion band development. The potential genes' signals were examined using a semi-quantitative approach. Significant correlations were observed between the expression of CDX1 (p <.001) and SHH (p=0.032) genes in fibroblasts from congenital intra-abdominal adhesions compared to fibroblasts from control peritoneal tissue. Statistically significant very strong correlations were found between the CDX1 and IHH comparing endothelium and fibroblast cells in congenital abdominal adhesion bands. There was no statistically significant difference found in the distribution of IHH, FOXA2, GATA4, and FOXF1 between the fibroblasts and endothelium of the patients compared to the control group. The presence of notable distinctions and diverse associations suggests the potential involvement of numerous morpho-pathogenetic processes in the development of intraabdominal adhesions.
RESUMEN
Located in northern Europe, Latvia is one of the three Baltic States with a population of 1.9 million. The country has a rich history of medical education spanning a century and is becoming an emerging global hub for medical education. Although the surge in international students has been beneficial for the development of educational and research infrastructure, increasing demands from local students, along with institutional capacity constraints, have overburdened the available resources. Substantial investments are being made to adapt to the rapidly changing geopolitical and techno-biomedical landscape. This perspective paper presents an overview of the country's medical education system, its challenges, and prospects from pre-university to doctoral level.
RESUMEN
Congenital upper extremity deformities are rare, the reported incidence is from 0.15% to 0.2%. The thumb is very important for a hand's functionality, as it provides up to 50% of its total performance. Proper pinch grip formation at the age of 12 to 16 months is part of normal development; however, no functional development can affect a child's psychoemotional development. Well-described techniques such as third or fourth superficial flexor transposition can be found in the literature. There is a paucity of studies on using the extensor indicis proprius (EIP) transposition for stabilization of the ulnar collateral ligament for the first metacarpophalangeal joint (MCPJ). Techniques for the usage of EIP tendon for the reconstruction of absent extensor pollicis longus tendon are more commonly practiced as they create abduction and extension for the thumb hypoplasia grade II-IIIa. We performed EIP transposition with subperiosteally fixation for the ulnar collateral ligament stabilization for thumb hypoplasia patients with a mean age of 38 months (11 to 128) and grade II (n=9), grade IIIa (n=4), and grade IIIb (n=1). Long-term follow-up (2 to 10 y) for the esthetical and functional study was performed. Patients and parents are satisfied with functional and esthetic outcomes. We believe that the EIP tendon transposition can be an alternative method for thumb hypoplasia patients grade II-IIIa reconstruction.

Osteosarcoma is a common bone tumor for pediatric patients that has a complex treatment including chemotherapy and radical surgical resection. There are few functional leg reconstruction possibilities described in the literature for pediatric patients due to limited growth potential. The aim of this report is to show long-term results using double vascularized growth plate flaps for the long segmental tibial reconstruction in growing children with satisfactory functionality and preserved limb growth without the use of permanent foreign materials. Three patients with sarcoma in the proximal part of the tibial bone were treated with complex therapy that included preoperative chemotherapy, radical resection of proximal metaepiphysis with tibial growth plate and half of the diaphysis and transplantation of double fibula growth plate flaps-the pedicled ipsilateral and the contralateral as a microvascular flap. The first patient, a male, 13 year with periosteal sarcoma, underwent 17 cm tibial resection with transplantation of the ipsilateral fibula 20 cm and contralateral fibula 20.1 cm, and continued follow-up for 6 years. The second patient, a male, 6 years of age with osteosarcoma, had 14 cm tibial resection with 16 cm ipsilateral and 16.1 cm contralateral fibular transplantation, continued follow-up for 5 years. The third patient, a female, 12 years of age with osteosarcoma, underwent 14 cm tibial resection with 15.4 cm ipsilateral and 15.9 cm contralateral fibular transplantation, and current follow-up of 1 year. Double fibular growth plate transfer is limb-sparing method for a proximal tibial reconstruction with natural growth potential for the pediatric patients.

Background and Objectives. The aim of this study is to determine the prevailing microbiota in samples from pediatric patients with acute appendicitis, as well as evaluate the antibacterial sensitivity of the isolated microorganisms, comparing the data obtained with the clinic's antibacterial therapy guidelines. Materials and Methods. The study group consisted of 93 patients between the ages of 7 and 18. All patients underwent a laparoscopic or conventional appendectomy. The children were hospitalized with signs and symptoms suggestive of acute appendicitis. Microbiological cultures from the appendix and abdominal cavity were collected intraoperatively. Results. E. coli was identified in most cases irrespective of the clinical presentation of acute appendicitis. Most strains were susceptible to ampicillin and amoxicillin/clavulanic acid. Five strains of E. coli produced extended spectrum beta-lactamase (ESBL). Pseudomonas aeruginosa (P. aeruginosa) was the second most commonly isolated causative agent. Furthermore, it was common in cases of acute complex appendicitis. Most strains of P. aeruginosa were resistant to amoxicillin/clavulanic acid, ertapenem, ampicillin and cefotaxime, yet were susceptible to ceftazidime. Regardless of the clinical presentation, the samples yielded mixed isolates. Conclusion. E. coli is the main causative agent of acute appendicitis in the pediatric population displaying susceptibility to various antibiotics. P. aeruginosa was more prevalent in cases of acute complex appendicitis. P. aeruginosa isolates were susceptible to ceftazidime; however, they were resistant to cefotaxime, which should, therefore, be removed from guidelines for empirical antibacterial treatment of acute appendicitis due to phenotypic resistance of P. aeruginosa. We recommend antibiotics with distinct implementation to avoid antibiotic resistance.

Primary obstructive megaureter (POM) morphogenesis is not fully known. The aim of the study was to evaluate the appearance of different factors that might take part in the pathogenesis of POM. Megaureter tissues of 14 children were stained with hematoxylin and eosin as well as with immunohistochemistry for protein gene product 9.5, nerve growth factor receptor, transforming growth factor beta 1 (TGFß1), fibroblast growth factor receptor 1 (FGFR1), matrix metalloproteinase 2 (MMP-2), angiotensin 2 receptor type 2, and sonic hedgehog (SHH) protein. Apoptosis was detected by terminal dUTP nick-end labeling reaction. POM tissues revealed transitional epithelium with scattered vacuolization, submucosa with inflammatory cells, and focally vacuolized and chaotically organized muscle layers. Apoptosis, appearance of MMP-2, FGFR1, and SHH prevailed, but TGFß1 positive cell number was lower in patients. Correlation between MMP-2 in epithelium and endothelium, FGFR1 and MMP-2 in epithelium, and TGFß1 in epithelium and connective tissue in patients was detected. POM morphopathogenesis involves an apoptotic cell death of epithelium and smooth muscle as well as tissue degradation in epithelium and connective tissue of the ureter wall. The decrease of tissue growth through diminished TGFß1 expression and stimulation of FGFR1 and MMP-2 suggests a disbalance of tissue remodelation in the megaureter wall.

Radial absence or severe hypoplasia in radial longitudinal deficiency (RLD) is most commonly treated through stabilization of the carpus on the ulna (centralization or radialization) with or without preliminary distraction. Alternative methods include bone transfer to replace the absent or deficient radius using the proximal fibula, vascularized or nonvascularized, and more recently the transfer of a vascularized second metatarsophalangeal joint. There is paucity of articles suggesting vascularized fibula growth plate transfer for RLD grade III where proximal part of radius can be found and none about double fibular growth plate transplantation. We developed new technique a bilateral growth plate transplantation for the pediatric patient with unilateral RLD stage IV (Bayne and Klug). Totally 2 patients were operated using new technique. No vascular problems occurred and no peroneal nerve damage were observed at the follow-ups. Annual growth was determined on x-rays at the 1 and 2-year follow-ups measuring 0.75 to 0.9 cm with open growth plates. The x-rays also show no changes that can harm the long-term growth potential in the forearm, demonstrating this technique's capacity to achieve better results for forearm length and functionality in comparison to the Vilkki procedure or radialization operation and there is no need to sacrifice second toe. Thumb reconstruction can be done at age 3 or 4 years using pollicization or toe-to hand transplantation techniques. The patients and parents are satisfied with functional and esthetic outcomes. We believe the double fibular growth plate transplantation is a promising method to use to reconstruct unilateral RLD grade IV.

This case series study consists of six children, aged 5-16 years, admitted to a centralized tertiary paediatric hospital serving a population of 1.9 million with acute appendicitis in the setting of SARS-CoV-2 infection. From the beginning of the pandemic in March 2020 until August 2021, 121 COVID-19-positive children were admitted to the hospital. A total of 49 (40.5%) of these patients presented with gastrointestinal symptoms, of which six were diagnosed with acute appendicitis. Five underwent an appendectomy, while one was treated conservatively. To date, it has been reported that appendicitis may have a plausible association with SARS-CoV-2 infection in children. With COVID-19 cases rising, every medical specialist, including all paediatric surgeons, must be ready to treat common acute diseases with SARS-CoV-2 infection as a comorbidity. Providers should consider testing for this infection in paediatric patients with severe gastrointestinal symptoms. Non-surgical treatment of acute appendicitis in children may gain new importance during and after the COVID-19 pandemic. Further studies are needed to prove the link of causality between COVID-19 and acute appendicitis in children.
RESUMEN
Calculous cholecystitis connects to inflammation and various complications. It is a common disease in the paediatric population, yet it is still uncertain how inflammation factors are involved in its morphopathogenesis. Twenty calculous cholecystitis surgery tissue samples were obtained from 20 children. As a control, seven unaffected gallbladders were used. Tissues were immunohistochemically stained for IL-1α, IL-4, IL-6, IL-7, IL-8, IL-10, and IL-17A, and the slides were inspected by light microscopy. To evaluate statistical differences and correlations between interleukins, Mann-Whitney U and Spearman's tests were used. Statistically significant difference between patient and control gallbladder epithelium was for IL-1α and IL-17A, but connective tissue-IL-1α, IL-4, IL-6, IL-7, IL-8, and IL-17A positive structures. A strong positive correlation in patients was detected between epithelial IL-1α and IL-1α in connective tissue, epithelial IL-6 and IL-7, IL-6 and IL-17A, IL-7 and IL-10, IL-7 and IL-17A, as well as between IL-6 and IL-7, IL-7 and IL-10 in connective tissue. The increase of IL-1α, IL-4, IL-6, IL-7, IL-8 and IL-17A positive structures suggests their role in the morphopathogenesis of calculous cholecystitis. The correlations between interleukins in epithelium and in connective tissues prove that the epithelial barrier function and inflammatory response in deeper layers are sustained through intercellular signalling pathways.
RESUMEN
PURPOSE: This prospective, single-center cohort study analyzes the potential of inflammatory protein mediator leucine-rich alpha-2 glycoprotein 1 (LRG1) for the early and accurate diagnosis of acute appendicitis (AA), and differentiation of acute complicated (AcA) from uncomplicated appendicitis (AuA). METHODS: Participants were divided into the AcA, AuA, and control groups, and their serum (s-LRG1) and urine LRG1 (u-LRG1) levels were assayed preoperatively on the second and fifth postoperative days. RESULTS: 153 patients participated, 97 had AA. Preoperative u-LRG1 with a cut-off value of 0.18 µg/mL generated an area under the receiver operated characteristic (AUC) curve of 0.70 (95% CI 0.62-0.79) for AA versus control (p < 0.001), while the results for AcA versus AuA were not significant (AUC 0.60, 95% CI 0.49-0.71, p = 0.089). The s-LRG1 levels of AA versus the control with a cut-off value of 51.69 µg/mL generated an AUC of 0.94 (95% CI 0.91-0.99, p < 0.001). The cut-off value of s-LRG1 was 84.06 µg/mL for diagnosis of AcA from AuA, and therefore, significant (AUC 0.69, 95% CI 0.59-0.80, p = 0.001). CONCLUSIONS: LRG1 exhibited excellent diagnostic performance as an inexpensive, non-invasive, rapid, and accurate biomarker able to reflect the pathogenesis of AA. LRG1 has the potential to replace advanced imaging to diagnose clinically ambiguous AA cases.
RESUMEN
Congenital diaphragm hernia (CDH) is a congenital disease that occurs during prenatal development. Although the morbidity and mortality rate is rather significant, the pathogenesis of CDH has been studied insignificantly due to the decreased accessibility of human pathological material. Therefore the aim of our work was to evaluate growth factors (transforming growth factor-beta (TGF-ß), basic fibroblast growth factor (bFGF), insulin-like growth factor 1 (IGF-1), hepatocyte growth factor (HGF)) and their receptors (fibroblast growth factor receptor 1 (FGFR1), insulin-like growth factor 1 (IGF-1R)), muscle (dystrophin, myosin, alpha actin) and nerve quality (nerve growth factor (NGF), nerve growth factor receptor (NGFR), neurofilaments (NF)) factors, local defense factors (ß-defensin 2, ß-defensin 4), programmed cell death (TUNEL), and separate gene (Wnt-1) expression in human pathological material to find immunohistochemical marker differences between the control and the CDH patient groups. A semi-quantitative counting method was used for the evaluation of the tissues and structures in the Biotin-Streptavidin-stained slides. Various statistically significant differences were found in immunoreactive expression between the patient and the control group tissue and the morphological structures as well as very strong, strong, and moderate correlations between immunoreactives in different diaphragm cells and structures. These significant changes and various correlations indicate that multiple morphopathogenetic pathways are affected in CDH pathogenesis. This work contains the evaluation of the causes for these changes and their potential involvement in CDH pathogenesis.
RESUMEN
Rhabdomyosarcoma (RMS) is a common soft tissue sarcoma in childhood, however, it is very rare in the neonatal period (0.4-2% of cases). This case depicts a boy, who presented with RMS at two weeks of age, but officially diagnosed at the age of three months. MRI and scintigraphy determined a soft tissue tumor in the soleus muscle, while biopsy confirmed embryonal RMS with high mitotic activity (Ki67 (monoclonal antibodies) ~80%). CWS (Cooperative Weichteilsarkom Studiengruppe)-2012 with I2VA (ifosfamide, vincristine, actinomycin) chemotherapy regimen was administered per protocol. Surgical treatment was performed at age of six months and 18 days. The operation consisted of radical tumor resection and total triceps surae with partial fibula resection. Immediate reconstruction of triceps muscle was accomplished using a vascularized functional musculocutaneous vastus lateralis flap. Functional outcome was measured using the Lower Extremity Functional Scale (LEFS) and the Foot and Ankle Outcome Score (FAOS) with the results of 92.5% and 99% respectively.

PURPOSE: The study aim is to determine whether serum and urine interleukin-6 (IL-6) and neutrophil gelatinase-associated lipocalin (NGAL) can be included in the early diagnostic algorithm for pediatric appendicitis. METHODS: Prospective single-center cohort study included 92 children divided into control, acute complicated appendicitis (AcA) and acute uncomplicated appendicitis (AnA) groups. Serum and urine samples were assayed for IL-6 and NGAL preoperatively, and on the second and fifth postoperative days. Intraoperative and bacteriological findings divided the appendicitis patients. RESULTS: Average serum biomarker levels were higher in appendicitis patients versus the control, and the following values were produced via receiver operating characteristic (ROC) analysis. NGAL and IL-6 cutoff values were 113.95 ng/ml and 24.64 pg/ml, respectively, NGAL had 68.3% sensitivity and 65.5% specificity, while IL-6 had 72.6% and 86.2%. Comparing AcA and AnA, IL-6 was the only biomarker of significance yielding 77.4% sensitivity and 58.1% specificity with a 26.43 pg/ml cutoff value. Urine biomarkers were non-specific in differentiation appendicitis severity and ultimately, between infectious and non-infectious disease. CONCLUSION: Although NGAL provided measurable useful diagnostic information in evaluating children for appendicitis, its values were not sufficient for appendicitis severity. Serum IL-6 remains a strong biomarker for suspected acute appendicitis and has promising results predicting its severity.

Congenital thumb hypoplasia is a rare deformity of the upper extremity. The classification of thumb hypoplasia was created by Blauth in 1967 (types I to V). The base of the first metacarpal bone is absent for hypoplasia types IIIb to V, therefore, toe-to-hand transplantation is not recommended. A stable first carpometacarpal joint has been considered a mandatory factor for a successful toe-to-hand transplantation. The aim of this study is to describe a new technique for thumb reconstruction with the second toe transfer and metatarsophalangeal joint (MTPJ) arthrodesis, which can provide a five-digit hand and restore thumb functionality for thumb hypoplasia IIIb to V. We performed second toe-to-hand transplantation with MTPJ arthrodesis for 3 pediatric patients (mean age, 69 mo) with congenital thumb hypoplasia IIIb (n=2), grade V (n=1). Long-term follow-up evaluated the functions and esthetics of the hands for grade IIIb patients (n=2). We believe the second toe transfer with MTPJ arthrodesis transplantation is a promising method for reconstructing a full-length congenital or traumatic thumb absence for the pediatric population.

BACKGROUND AND OBJECTIVES: Congenital thumb hypoplasia is a rare deformity of upper extremity. The incidence for thumb hypoplasia grade II-V is 1:10,000 newborns per year in Latvia. A technique for extensor indicis proprius (EIP) tendon transfer with subperiosteal fixation was developed and used for thumb hypoplasia grades II and IIIa. Pollicization or second-toe-to-hand transplantation with metatarsophalangeal (MTP) joint arthrodesis was used for the reconstruction of hypoplasia grade IIIb-V. The aim of this retrospective cohort study is to evaluate the outcomes for reconstruction techniques used in one surgical center during a ten-year period by one surgeon to evaluate functional and aesthetical outcomes for new techniques. MATERIALS AND METHODS: In total, 21 patients were operated on during 2007-2017, and 18 of these patients were involved in this study. Long-term follow-up was completed to evaluate the functions and aesthetics of the hands. RESULTS: disabilities of the arm, shoulder and hand (DASH) was 9.35 (8-10.7) for the second-toe-to-hand with MTP joint arthrodesis transplantation method for pollicization method 19.8 (6-26.7), and for the EIP tendon transposition, 14.54 (0.9-56.3). CONCLUSIONS: The postoperative functional parameters of congenital hand hypoplasia patients, regardless of the surgical method, are worse than the functional results of healthy patients. The use of the second-toe-to-hand with MTP joint arthrodesis transplantation method provides patients with congenital hand IIIb-V hypoplasia a stable and functional first finger formation. The functional results are comparable to the clinical results of the pollicization method while ensuring the creation of a five-digit hand.

The first toe-to-hand transplantation was done in 1898 by Nicoladoni. It was a staged procedure and the toe flap was based on a pedicle. With advancement of optical instruments and microsurgeons' skills in 1964 the first microvascular toe-to-hand transplantation on a rhesus monkey was done. The technique's development has not stopped, many authors have modified it to achieve better outcomes for both traumatic and congenital hand defects. The most commonly used toes for transplantation are first, second, and second to third toe block. Well described plantar and dorsal vascular systems for first web space vessels as well as possibility to perform successful perforator anastomosis allows us to improve toe-to-hand transplantation further. There is a paucity of studies on single fourth toe-to-hand transplantation. We performed fourth-toe transplantation for three pediatric patients (mean age, 73 mo) with congenital (n=2) and traumatic (n=1) hand defects. Common plantar digital arteries were used for blood supply to the transplanted toes. No vascular problems occurred, and all transplanted toes survived. Patients and parents are satisfied with functional and esthetic outcomes. Early podometry results show insignificant changes which should not harm the foot in the long-term. We believe the fourth-toe transplantation is a promising method to use to reconstruct congenital or traumatic absence of digits for pediatric population.

BACKGROUND AND OBJECTIVE: The diagnostic role of serum cytokines depends on the etiology and pathogenesis of acute appendicitis (AA) and acute mesenteric lymphadenitis (AML). The aim of this study was to evaluate differences in cytokine levels between AA and AML. MATERIALS AND METHODS: Data of 7- to 18-year-old children were collected prospectively from October 2010 to October 2013. There were 31 patients with AA (AA group), 26 with AML (AML group), and 17 with elective non-inflammatory surgical disease (control group). Serum levels of IL-10, IL-12(p70), IL-1ß, IL-4, IL-6, IL-8, IL-17, MCP-1, EGF, TNF-α and white blood count (WBC) were measured three times consecutively in each group. RESULTS: The level of IL-6 and IL-10 was significantly higher in the AA group than the AML group at the first measurement (8pg/mL vs. 3.2pg/mL, P=0.000; 6.1pg/mL vs. 3.2pg/mL, P=0.005, respectively). There was a significant difference observed in time dynamics of concentration of IL-6 and MCP-1 for AA and AML. The area under the curve (AUC) was 0.77 (95% CI 0.64-0.89; P=0.001) for IL-6 with a cut-off value of 4.3pg/mL (67.7% sensitivity and 76.9% specificity) for AA 1h before surgery. The AUC for WBC was 0.72 (95% CI 0.58.4-0.85; P=0.005) with a cut-off value of 10.7×103/µL (sensitivity 71.0% and specificity 46.2%). CONCLUSIONS: Serum IL-6 with a cut-off value of 4.3pg/mL and WBC with a cut-off value of 10.7×103/µL assessed together will yield more sensitivity for AA.

BACKGROUND AND OBJECTIVE: There is a high incidence of childhood tuberculosis in Latvia, including children aged less than 1 year, while BCG-associated lymphadenitis is one of the most frequent adverse events requiring surgical treatment. The aim of this study was to analyze the incidence of purulent BCG adenitis through-out the population of Latvia after the introduction of BCG-SSI(®) vaccine and to evaluate the treatment results. MATERIAL AND METHODS: The study included 194 patients. All patients had received the BCG-SSI(®) vaccine during the first week of life routinely or at a later time according to the indications. The indications for surgical treatment were lymph node destruction also affecting the skin. All patients in this study received surgical treatment - the affected lymph node extirpation. RESULTS: The mean age of the patients was 5.12±0.96 months. A total of 172 patients had purulent axillar lymphadenitis, 14 had purulent supraclavicular lymphadenitis, 8 patients had lymphadenitis at both localizations. During the whole study period the incidence of BCG adenitis varied from 0.02% to 0.36%, while the mean rate was 0.11%±0.08% from 184,068 vaccinated children during the study period. We observed an increasing trend in the incidence of BCG lymphadenitis during the study period. The primary and complete healing rate at the end of period was 99.5% (n=193) following an affected lymph node extirpation. The mean hospitalization time after the operation was 3.71±0.18 days. CONCLUSIONS: The incidence of BCG-SSI(®) vaccine associated purulent lymphadenitis varied widely with an increasing trend, followed by the return to the product characteristic limits. Indications for the surgical treatment should not be changed. Extirpation of the purulent BCG adenitis is a safe treatment method and leads to the primary wound healing in the majority of cases.

BACKGROUND: Body weight, length and head and thoracic circumference are routinely measured in obstetric and neonatal departments. Reference values for these measurements have been established for the neonatal population. Neonatal abdominal circumference is not routinely measured, and no reference values for this measurement have been determined. To evaluate the increase in abdominal circumference in newborns with abdominal pathology such as necrotizing enterocolitis, information about normal abdominal circumference in healthy neonates shortly after birth is needed. The aim of this study was to determine the correlation between abdominal circumference and birth weight by measuring the abdominal circumference of premature neonates soon after birth. METHODS: Abdominal circumference was measured within 30 min of birth in 220 neonates born between 23 and 35 weeks' gestation. RESULTS: There was no statistically significant difference in abdominal circumference between boys and girls in the study population. A specific formula for estimating normal abdominal circumference was developed: y = 0.0053x + 14.83 (y = abdominal circumference in cm; x = body weight in g; 0.0053 = regression coefficient; 14.83 = regression constant). CONCLUSION: A positive linear correlation between abdominal circumference and birth weight was found in infants at birth. The correlation can be summarized as a linear regression equation. Further studies are needed to investigate possible factors associated with abdominal circumference in fed versus unfed preterm infants.
