As a consequence Polish Government made a decision to go into a lockdown in order to secure the population against SARS-CoV-2 outbreak what had its major influence on the Polish Health Care System. All of the social and medical factors caused by the pandemic might influence children’s health care, including urgent cases. The aim of this survey was the analysis of medical charts with focus on the course and results of surgical treatment of children who underwent appendectomy before and during the COVID-19 pandemic. Material and methods: We performed analysis of charts of 365 subjects hospitalized in the Pediatric Surgery Department from 1st January 2019 to 31st December 2020 because of acute appendicitis. Patients were divided into two groups—those treated in 2019—b...

The optimal management of neonatal simple ovarian cysts is still a matter of discussion. MATERIALS Authors present four cases of neonatal ovarian cysts treated in Pediatric Surgery Clinic of Medical Academy in Bialystok in the period of 2002-2003. Three girls were managed conservatively--they are still in outpatient care. One girl was managed surgically. CONCLUSIONS The main aim of treatment is to preserve the ovary. Uncomplicated prenatal ovarian cysts should be treated depending on size and echographic patterns at birth.

Due to the existing risk of developing tumors in dysgenetic gonads, the patient was admitted to the clinic for prophylactic gonadectomy The operation was then postponed as a result of rapid progression to end-stage renal failure, and the patient was placed on hemodialysis. During subsequent laparoscopy both ovaries and dysgenetic gonads were resected. Histopathological examination revealed the presence of both seminal ducts and epididymis. Early prophylactic resection of dysgenetic gonads, such as was undertaken in this patient, is indicated in children with Frasier syndrome to prevent the development of germ cell tumors.

The purpose of this novel human study, was to characterize inflammatory response in children undergoing laparoscopic cholecystectomy, by analyzing changes in selected inflammatory mediators: C-reactive protein concentration and circulating 20S proteasome activity following surgical injury and to correlate them with the duration of the surgical procedure. Plasma C-reactive protein concentration (CRP) was determined by standard biochemical laboratory procedures. Proteasome activity in the plasma of children was assessed using Suc-Leu-Leu-Val-Tyr-AMC peptide substrate. Statistically significant increase in the plasma proteasome activity and C-reactive protein concentration, was noted (p < .05) in children after laparoscopic cholecystectomy. We found the correlation between the 20S proteasome activity and the length of the procedure. In children undergoing longer lasting laparoscopic cholecystectomy the proteasome activity was much higher than in patients having shorter surgical procedure. The CRP concentration and 20S proteasome activity significantly increase after surgery, but only 20S proteasome activity correlate with the length of the surgery. This may confirm that CRP is only an indicator of pathological state, while the function of the proteasomes is more complex because of their participation in the processes of repair and wound healing, and in the removal of damaged proteins.

MATERIAL AND METHODS 31 children scalded by hot water who were managed at the Department of Paediatric Surgery between 2014-2015, after primarily presenting with burns in 4-20% TBSA were included into the study (age 9 months up to 14 years, mean age 2,5+1 years). There were 10 girls and 21 boys. Venous blood samples were drawn 2-6h, and 12-16h after the thermal injury, and on the subsequent days 3, 5 and 7. The matrix metalloproteinase-2, collagen type IV and laminin-5 concentrations were assessed using Surface Plasmon Resonance Imaging by the investigators blinded to the other data. RESULTS The MMP-2, laminin-5 and collagen type IV concentrations in the blood plasma of patients with burns, were highest 12-16h after thermal injury, the difference was statistically significant. The MMP-2, laminin-5 and collagen type IV concentrations measured 3 days, 5 days and 7 days after the thermal injury, slowly decreased over time, and on the 7th day reached the normal range, when compared with the concentration measured in controls. CONCLUSION Current work is the first follow-up study regarding MMP-2 in burns. MMP-2, laminin-5 and collagen type IV levels were elevated early after burn injury in the plasma of studied patients, and were highest 12-16h after the injury. MMP-2, laminin-5 and collagen type IV levels were not proportional to the severity of the burn. We believe in the possibility that the gradual decrease of MMP-2, collagen type IV and laminin-5 concentrations could be connected with the process of healing, but to prove it, more investigation is needed in this area. The SPR imaging biosensor is a good diagnostic tool for determination of MMP-2, laminin-5 and collagen type IV in blood plasma of patients with burns.

Cathepsin B (CatB) belongs to a family of lysosomal cysteine proteases and plays an important role in intracellular proteolysis. Objectives. The concentration of CatB and 20S proteasome was evaluated in the serum of children with appendicitis, before and after surgery, on a basis of an innovative method for determining biomolecules concentration-surface plasmon resonance imaging (SPRI) biosensor. Material and methods. Forty-two children with acute appendicitis, who were treated at the Department of Pediatric Surgery (Medical University of Bialystok, Poland), were randomly included into the study (age: 5-17 years, mean age: 11.5 ±1 year). There were 15 girls and 27 boys in the study group. Eighteen healthy, age-matched subjects, admitted for planned surgeries, served as controls. Exclusion criteria were the following: severe preexisting infections, immunological or cardiovascular diseases that required longterm medication, and complicated cases of appendicitis with perforation of the appendix and/or peritonitis. Results. The CatB concentrations in the blood plasma of patients with acute appendicitis were elevated before surgery, they were the highest 24 h after surgery, and were above the range of concentrations measured in controls; the difference was statistically significant. The CatB concentration measured 72 h after the operation was decreased, but still did not reach the normal range when compared with the concentration measured in controls (p < 0.05). Conclusions. Cathepsin B concentration may reflect the metabolic response to acute state of inflammation, surgical intervention in the abdominal cavity and the process of gradual ebbing of the inflammation. The method of operation-classic open appendectomy or laparoscopic appendectomy-does not influence the general trend in the CatB concentration in children with appendicitis. There is a strong positive correlation between the CatB and 20S proteasome concentrations 24 h after surgery. The SPRI method can be successfully used for determining the concentration of active forms of enzymes presented in lysosomes in the diagnosis of inflammatory conditions in the abdominal cavity.

Because of its simplicity and effectiveness, percutaneous endoscopic gastrostomy (PEG) is nowadays considered the method of choice. To prevent complications, in children after prior abdominal and gastric surgeries, several methods have been reported to verify the anatomic relationship between the stomach and adjacent organs prior to gastric puncture. The aim of the study: we wanted to present our experience with the use of laparoscopic monitoring during the PEG procedure. Patients and methods Our case series include twelve patients who had had LAP-PEG procedure done after prior abdominal or gastric surgery. Nine patients were previously treated with ventriculoperitoneal shunts because of hydrocephalus. Two patients were previously operated on because of gastro-esophageal reflux. One patient was previously surgically treated because of Hirschsprung disease. Age at LAP-PEG ranged from 1 year 5 months to 17 years 1 month (mean 6 years 7 months) and weight ranged from 9 to 42 kg. The time between previous abdominal surgery and PEG insertion procedure ranged from 1 year 3 months to 17 years (mean 5 years 10 months). Results Mean duration of LAP-PEG was 41 min. In all patients, LAP-PEG was performed safely without perioperative complications. The mean length of hospital stay was 4 days (range from 3 to 6 days). Conclusions We believe that laparoscopic assistance diminishes the risk of major complications related to the PEG tube insertion procedure in children after previous laparotomy. Furthermore, adequate fixation of the stomach to the abdominal wall during LAP-PEG prevents the development of leakage and peritonitis. LAP-PEG should be considered the method of choice for obtaining enteral access in children after prior abdominal and especially gastric surgeries.

The objective of this study was to describe daily functioning of both caregivers and their children with gastrostomy tube. Using a semistructured questionnaire, this descriptive study examined perceptions of feeding and adherence to feeding recommendations for caregivers of children with neurological disabilities and gastrostomy tube. The questionnaire covered various aspects of child’s gastrostomy care, ranging from changing buttons, method of feeding, tolerance of diet, and problems with the gastrostomy site and device to how gastrostomy feeding has affected their lives. Parents and carers of 44 children completed a questionnaire. Children in the study (n = 44) had had a gastric tube in place for at least 1 month, and children with cerebral palsy had been assessed at level V of the Gross Motor Function Classification System. Most caregivers reported improvement in the children following placement and significant improvements in their own social functioning. Carers reported a significant reduction in feeding times, increased ease of drug administration, and reduced concern about their child’s nutritional status. Most caregivers reported a beneficial effect on their children of the gastrostomy feeding tube placement—improved nutrition and decreased health complications. Consistent with prior research, this study found that the majority of caregivers were satisfied with the gastrostomy tube placement results and felt the improvement in the quality of their life.

This review includes an update on the current knowledge on pathogenesis, a discussion on indications for treatment, and a review of the mechanisms underlying the different treatment methods. Although most infantile hemangiomas require only active observation because of their natural course, which results in involution, about 10% present with complications that require immediate treatment. The basic treatment includes systemic and topical options. In cases of insufficient response or rebound growth, other forms of treatment should be considered. In some cases, combined therapy might be initiated.

Despite improved medical care, many burn patients develop permanent scars, which are a serious cosmetic, functional and psychological burden. We present the possible use of a pulsed dye laser (PDL) and an ablative fractional CO2 laser (AFCL) in the treatment of post-burn scars, with particular emphasis on the paediatric population. PDL is intended to reduce scar redness through selective photothermolysis of blood vessels to reduce local hypervascularity. This type of laser can be also used to reduce pruritus, most likely by modifying local cytochemical reactions. Ablative fractional carbon dioxide laser therapy (AFCL) may be optionally used to improve scar texture and reduce its thickness. AFCL can also restore normal function of the scarred area. It causes vaporisation of scar tissue fragments, thereby stimulating collagen reconstruction. The fact that PDL and AFCL can be safely combined during the same procedu...

The aim of this study was to investigate the rate of change in proteasome chymotrypsin-like (ChT-L) activity and C-reactive protein concentration depending on the degree of tissue damage and their correlation with prealbumin concentrations in children before and after abdominal surgery. This experimental study included children who underwent abdominal surgery between 2015 and 2017. Plasma prealbumin concentrations and C-reactive protein levels (CRP) were determined by standard biochemical laboratory procedures. Proteasome activity was assessed using a Suc-Leu-Leu-Val-Tyr-AMC peptide substrate. Elevation of plasma proteasome activity was noted in children after laparoscopic and open abdominal surgeries. However, 20S proteasome activity in children undergoing conventional open surgery was signifi...

In full-term newborn boys its incidence is estimated at 2-5%. During the first three months of life, in half of these boys the testicles will descend spontaneously into the scrotum, but at the end of the first year of life 1% of boys will have cryptorchidism. Among boys born prematurely, about 30% of them have undescended testicles at birth, but also in such cases approximately 80% of undescended testes descend by the third month of life. The authors discuss the epidemiology, pathophysiology, aetiology, and treatment of undescended testicle in boys.

The aim of this study was to investigate the rate of change in proteasome chymotrypsin-like (ChT-L) activity and C-reactive protein concentration depending on the degree of tissue damage and their correlation with prealbumin concentrations in children before and after abdominal surgery. This experimental study included children who underwent abdominal surgery between 2015 and 2017. Plasma prealbumin concentrations and C-reactive protein levels (CRP) were determined by standard biochemical laboratory procedures. Proteasome activity was assessed using a Suc-Leu-Leu-Val-Tyr-AMC peptide substrate. Elevation of plasma proteasome activity was noted in children after laparoscopic and open abdominal surgeries. However, 20S proteasome activity in children undergoing conventional open surgery was signifi...

The aim of the study: Investigation of the concentrations of MMP-1 (Matrix metalloproteinase-1), MMP-2 (Matrix metalloproteinase-2) and fibronectin in the saliva of patients planned for endodontic treatment or surgical extraction. Material and methods: Seventy-five patients with caries and 14 healthy subjects were included in the study. Subjects were divided into group 1, in which 50 patients were planned for endodontic treatment, and group 2, in which 25 patients were planned for surgical extraction. For the measurements, we used a surface plasmon resonance imaging biosensor. Results: We found higher levels of MMP-1, MMP-2 and fibronectin in the saliva of patients planned for dental treatment than in healthy donors. We found lower concentrations of MMP-2 in subjects planned for surgical extraction, than in patients planned for endodontic treatment; however, there were no such differences in salivary concen...

In full-term newborn boys its incidence is estimated at 2-5%. During the first three months of life, in half of these boys the testicles will descend spontaneously into the scrotum, but at the end of the first year of life 1% of boys will have cryptorchidism. Among boys born prematurely, about 30% of them have undescended testicles at birth, but also in such cases approximately 80% of undescended testes descend by the third month of life. The authors discuss the epidemiology, pathophysiology, aetiology, and treatment of undescended testicle in boys.
