The Impact of the COVID-19 Pandemic on the Most Common Diagnoses in Pediatric Surgery: Abdominal Pain, Acute Scrotum, Upper and Lower Extremity Injuries-Tertiary Center Experience.

OBJECTIVE: The coronavirus disease-19 pandemic has brought new patterns of behavior among patients and their parents. The reorganization of the health care system has reduced the number of elective surgical procedures in Croatia. In our study, we were interested in whether the pandemic has caused a statistically significant decrease in the number of examinations of children in the emergency department according to the most common diagnoses in pediatric surgery and whether there was a decrease in the number of emergency surgeries. MATERIALS AND METHODS: We retrospectively analyzed data from the Hospital Information System. The analysis included 15 months of the pre-coronavirus disease-19 period and 15 months of the coronavirus disease-19 period. The primary outcome of the study was to determine the cumulative number of all examinations and then to determine the number of examinations according to the most common diagnoses and, consequently, to determine whether there was a statistically significant decrease. The secondary outcome was to determine the cumulative number of all operations and then to determine the number of the most common emergency operations and, consequently, to see if there was a statistically significant decrease. RESULTS: In the 15 months of the pre- coronavirus disease-19 period, a total of 33 646 children were examined in the emergency department, while in the coronavirus disease-19 period, 26 831 were examined (P = .010). Although a decrease was recorded in all categories, a statistically significant decrease was recorded for diagnoses of abdominal pain (P = .007) and lower extremity injuries (P = .014). The total number of operations, due to strict measures and reduction of the elective program, decreased statistically significantly in the coronavirus disease-19 period (P < .0001). The number of most common emergency operations did not decrease statistically significantly. CONCLUSION: This study represents the first longer, 15-month experience of a pandemic in the only and largest children's hospital in Croatia. There is no doubt that coronavirus disease-19 had the effect of reducing the number of examinations in the emergency department for all the most common diagnoses, but the number of operations did not change significantly.

Specific small bowel injuries due to prolapse through vaginal introitus after transvaginal instrumental gravid uterus perforation: a review.

A small bowel prolapse through the vaginal introitus after a transvaginal instrumental gravid uterus perforation is a surgical emergency. To define the mechanisms of an irreversible, small bowel ischaemia due to small bowel prolapse through a vaginal introitus, ClinicalTrials.gov, PubMed, PubMed Central, and Google Scholar were searched. Out of the 81 articles screened, 28 cases of a small bowel evisceration through vaginal introitus were included. A small bowel obstruction severity grading was defined with risk factors; potential mechanisms of different severity grades after a transvaginal instrumental gravid uterine perforation with a vaginal evisceration. The duration of symptoms or a delay in the diagnosis did not change the incidence of the two most severe grades-mesenteric stripping and a small bowel degloving. Both obstruction types develop immediately during an instrumental abortion. The severity of obstruction does not influence the maternal outcome.

From Ataxia to Diagnosis of Askin Tumor - a Case Report.

Peripheral primitive neuroectodermal tumors (pPNET) are a group of extremely rare, aggressive, malignant tumors that are most often found in the thorax (Askin tumor), abdomen, pelvis, extremities and less frequently in the head and neck. The most important prognostic factor is the stage of the tumor. Significant progress both in surgery and in neoadjuvant and adjuvant chemotherapy and radiotherapy, as well as the improvement in diagnosis by cytogenetic and immunohistochemical analysis, should improve the survival rate. We report a case of a 14-year-old girl, with ataxic gait, cardiopulmonary compensated, without respiratory symptoms, who was referred to our hospital for further examination and treatment of newly discovered tumor of the left hemithorax. After a detailed radiological and laboratory investigation, next step was an extensive thoraco-neurosurgical surgery. After histopathological, cytological and molecular analysis, a diagnosis of Askin tumor was made.

Treating Giant Congenital Nevus With Integra Dermal Regeneration Template in a 9-Year-Old Girl.

Integra dermal regeneration template has been well established in treating deep extensive burns, but there are very few cases reported of treating large full-thickness skin defects such as giant nevi. Apart from psychological and cosmetic burdens, the giant congenital nevus carries increased risk of malignant alteration. We present the case of a 9-year-old girl with a giant congenital nevus on her left lower leg. A total excision was done and she was successfully treated with Integra (LifeSciences Corp, Plainsboro, NJ). Three weeks later, a thin split-skin graft was applied over the neodermal skin layer. The takeoff was 91%. Protected with the silver wound dressing, the rest of the wound healed. A donor site morbidity was minimal, and the final result was excellent both in aesthetic and functional aspects.

Bilateral Ovarian Torsion during Follow-up for Antenatally Detected Ovarian Cysts.

Ovarian torsion is a surgical emergency demanding timely diagnosis and treatment to prevent loss of the ovaries which if happens may result in functional and emotional consequences. Simple (less than 5cm in size) ovarian cysts require follow-up for potential self-resolution. We describe a case of antenatally detected bilateral ovarian cysts that developed bilateral ovarian torsions on follow-up, postnatally.

Rare Abdominal Wall Malformation: Case Report of Umbilical Cord Hernia.

The umbilical cord hernia is the rarest form of abdominal wall malformations, anatomically completely different from gastroschisis and omphalocele. It occurs due to the permanent physiological evisceration of abdominal organs into umbilical celom and persistence of a patent umbilical ring. The umbilical cord hernia is often mistaken for omphalocele and called "small omphalocele". Here we present a case of a female newborn with umbilical cord hernia treated in our Hospital. After preoperative examinations surgery was done on the second day of life. The abdominal wall was closed without tension. The aim of this article is to present the importance of the proper diagnose of these three entities and to stimulate academic community for the answer, is this umbilical cord hernia or small omphalocele.

Torsion of a mesenchymal hamartoma of the liver in a 1-year-old boy.

We report a case of a one-year-old boy who was referred to our clinic suspected of having acute abdomen. On physical examination, the abdomen was soft, diffusely tender with weak peristalsis. Ultrasonography and MRI of the right hemiabdomen demonstrated a well-defined, solid, expansive formation with slightly lobulated contours and an interspersed inhomogeneous structure with overall dimensions of 59 × 45 × 50 mm. After midline laparotomy was performed, a cystic tumor was found, twisted around a pedicle which was arising from the falciform ligament and it measured 5-6 cm in diameter. The tumor appeared to be necrotic. The mass was ligated and extirpated on the pedicle and sent for histopathological analysis. After the surgery, the boy was hemodynamically stable, without respiratory complications and all laboratory findings were within normal limits. Histopathological analysis showed that the tumor was composed of mesenchymal stroma with sparse glimpses of hepatocytes and bile ducts with partly cystic changes lined by orderly epithelium. Given the clinical data, histology and immunohistochemistry analysis (alpha-fetoprotein, CK8/18, hepatocyte, desmin and CD31) a diagnosis of a twisted mesenchymal hamartoma of the liver was made.

[THE SCALP AS A SPLIT-THICKNESS GRAFT DONOR IN THE TREATMENT OF A MASSIVE THERMAL INJURY]. / VLASISTE KAO DONOR TRANSPLANTATA DJELOMICNE DEBLJINE KOZE U LIJECENJU MASIVNE TERMALNE OZLJEDE.

We are presenting our initial experience with the utilization of the scalp as a donor for split thickness skin grafting in the treatment of massive thermal injuries. Rapid donor reepithelization, absence of hypertrophic scarring in the donor area, inconspicuous donor area and a large area for the procurement of grafts in the pediatric population are the advantages that are emphasized in the literature. The outcome in a 3-year-old boy who suffered a burn injury from an open fire in the family house on the 57% of his total body surface area (48% full thickness burn) showed that the "take rate", in the absence of a massive local infection, was around 80% and that the scalp can be utilized again as a donor area after a period of 14 days. Folliculitis and alopecia are complications that should be kept in mind when using this technique.

[STERNAL CLEFT ­ REPORT OF THREE CASES]. / RASCJEP PRSNE KOSTI ­ PRIKAZ TROJE BOLESNIKA.

During the last 25 years we surgically treated three patients with sternal cleft anomaly, aged from 6 weeks to 2 years. The aim of this case series is to present this extremely rare congenital anomaly and differences in the operative treatment of sternal cleft (SC) depending on patients age due to flexibility of the chest wall. Patients presented to us with signs of sternal cleft; displaced sternoclavicular articulations and paradoxical motion of the skin over the defect. Preoperatively we performed X-ray and computed tomography of the chest which revealed displaced sternoclavicular articulations with superior incomplete sternal cleft and echocardiography which showed orthotopic heart without malformations of the great vessels. Surgical treatment included primary closure in two infants and Sabiston's technique in a two-year-old girl. All three patients were successfully operated without complications.

[INITIAL EXPERIENCE WITH TOPICAL NEGATIVE PRESSURE THERAPY IN THE TREATMENT OF PEDIATRIC BURNS].

We are presenting the experience of the Referral Centre for Pediatric Traumatism of the Croatian Ministry of Health in the usage of topical negative pressure therapy (TNP) method for the treatment of pediatric burns. In the period of 20 months we have used negative pressure wound therapy method in eight children aged between 1.5 and 10 years. Burn injuries total body surface area ranged between 3% and 30%. TNP was used either for the wound bed conditioning or for the fixation of skin grafts. Average skin graft "take" was 86% eight days after surgery according to the evaluation by the senior author. Based on our initial experience, we can confirm that TNP is a very useful tool which enables good wound bed conditioning as well as a good fixation tool for skin grafts if the burned area does not exceed 30% of total body surface area.

Duodenal Duplication Cyst: A Rare Differential Diagnosis in a Neonate with Bilious Vomiting.

Bilious vomiting is a relevant sign in neonates that requires immediate evaluation and diagnosis. A duplication of the intestinal tract is a possible cause of obstruction if located distally to the major duodenal papilla of Vater and most of them involve the jejunum, stomach, or colon. Duodenal duplications are very rare and can have an endoscopic or surgical treatment after diagnosis. We present a case of a 16-day-old term newborn that consulted because of bilious vomiting and after evaluation with imaging and upper endoscopy, a duodenal duplication cyst was found at the level of the third portion causing compression of the intestinal lumen that required surgical resolution with duodenocystostomy.

Isolated fallopian tube torsion with partial hydrosalpinx in a premenarcheal girl: a case report.

INTRODUCTION: Isolated fallopian tube torsion as a complication of a preexisting hydrosalpinx is a rare finding in pediatric patients. The obvious rarity of this condition, its subtle diagnostic features and dissonant previous reporting about the appropriate therapeutic approach according to age, future conception capacity and potential complications of possible pregnancies make the decision about which surgical approach to use very difficult. In this report, we describe the case of a patient with such a presentation and review the literature. Very few similar reports of neosalpingostomy in pediatric patients have been published to date. CASE PRESENTATION: In our present report, we describe the case of an 11-year-old Caucasian prepubertal girl who presented to our hospital with complaints of abdominal pain in the right lower quadrant, nausea and vomiting. The diagnostic workup led us to conclude that she had a torsion of the right ovary, which was cystically altered. Exploratory surgery revealed a partial hydrosalpinx and consecutive isolated torsion of the fimbrial part. The proximal isthmic part of the fallopian tube was intact and vital. Restorative surgery was performed to create a neosalpingostomy on the viable isthmic part of the tube and remove the cystic and twisted fimbrial and infundibular parts. CONCLUSION: The surgical procedure described in this report is technically simple and feasible, but leaves doubts about the final outcome.

[A rare tumor of the lung in childhood--inflammatory myofibroblastic tumor]. / Rijetki tumor pluca u djecjoj dobi --inflamatorni miofibroblasticni tumor.

Inflammatory myofibroblastic tumor (IMT) is a rare benign neoplasm, mainly involving the lungs of the children. It represents 0.7% of all lung tumors. It was first described by Brunn in 1939.2 Diagnosis is very difficult and often only possible after resection of the tumor. We would like to present a case of pulmonary IMT in a 13-year-old girl who presented with symptoms like cough, shortness of breath, and chest discomfort. Chest X ray and computed tomography revealed the presence of a right lower lobe lung mass. Its clinical and radiological findings were diverse and non specific. The mass was removed in toto, histopathology confirmed the inflammatory myofibroblastic tumor of the lung. Intraoperative and postoperative courses were uneventful. The patient has been without any signs of relapse 2 years after the surgery.

Cystic lymphangioma of jejunal mesentery mimicking acute appendicitis: case report.

Cystic lymphangiomas of the small bowel mesentery are rare manifestations of intra-abdominal tumors. Usually, they are discovered incidentally during examination for an unrelated abdominal illness. We present a case of a 4-year-old boy who was admitted to our hospital because of the right lower quadrant acute abdominal pain suspect of acute appendicitis. At laparotomy, a giant, cystic, encapsulated and lipomatous mesenterial mass was found, 15 x 15 x 10 cm in size, infiltrating the jejunum. The tumor was located 70 cm from Treitz's ligament. Extirpation of tumor mass with intestinal resection of the involved loops was necessary. Pathologic examination confirmed the diagnosis of mesenteric cystic lymphangioma. Although they are rare, cystic mesenteric lymphangiomas should be considered as a possible cause of acute abdomen and treated with surgical resection. Prognosis after surgical removal is excellent.

Venomous snakebites in the Croatian North Dalmatia region.

AIM: The aim of this research project is to analyze the epidemiological, clinical and laboratory attributes of venomous snakebites and to ascertain the timely and efficient treatment at the location where the incident took place or in varying clinical conditions. METHODS: Epidemiological, clinical and laboratory data were collected from people who were bitten by venomous snakes as well as treatments at Zadar General Hospital during a span of eleven years (1999-2009) which were analyzed retrospectively. RESULTS: During that period, 93 people were bitten by venomous snakes of which 57 patients (62%) were male and 36 (38%) were female. In 82 cases (90%), the bite area was localized on the limbs while in the remaining 11 cases the bite area was located elsewhere. At the time of the venomous snakebite, 31 (33%) patients were performing leisure activities and 44 (47.31%) of them were at work. The most common local snakebite signs are swelling and pain at the bite site (93 patients; 100%), hematomas and ecchymoses (87 patients; 89%). Of the affected patients, 8 suffered from compartment syndrome and one person (0.97%) expired. CONCLUSION: Antivenom treatment for preventing possible allergic reactions should take place at the medical institution where the victim was transported. However, when transport is not immediately available or in cases where the victim shows clear signs of envenomation, antivenom treatment should be used immediately because its effect is weaker if the venom is allowed to run its course.

Suicide attempt by swallowing sponge or pica disorder: a case report.

INTRODUCTION: There are many ways how children with mental illness have actually tried to hurt themselves. Suicidal thinking or attempts always indicate that professional help is needed (2). Every object which can be potential dangerous should be removed but this is very difficult to do. Some of children with these symptoms had Pica diseases. Pica is a medical disorder characterized by an appetite for substances largely non-nutritive (e.g. metal, coal, soil, feces, paper, soap, gum, etc.) or an abnormal appetite for some things that may be considered foods. MATERIAL AND METHODS: The patient swallow sponge from a pillow over a long period of time and she came into our hospital with abdominal pain. She was 16 years old and had abdominal distension, vomiting, abdominal cramping and failure to pass gas or stool. Immediately we suspected mechanical blockade of the intestine. Diagnosis was clinically confirmed by X-rays of the abdomen and with ultrasound. RESULTS: The operative treatment was indicated and we found the proximal bowel distended and the distal segment collapsed. The part of bowel necrosis was removed and anastomosis was done. CONCLUSION: When patients are determined to attempt suicide or have Pica disorder it is very difficult to prevent.

Pulsed dye laser treatment of vascular lesions in childhood.

Almost all congenital vascular abnormalities affect the skin and are evident from birth or become so during the first few weeks of life. The two most common types of vascular birthmarks, hemangiomas and vascular malformations, may appear to be very similar but their course and treatment are different. Hemangiomas appear in the first few weeks of life and usually regress spontaneously over time. Vascular malformations are always present from birth even though they might not be apparent, never disappear and often grow during the person's lifetime and may vary extremely from high blood flow lesions, sometimes located in critical sites that may be life-threatening to asymptomatic spots of mere aesthetic concern. Laser therapy nowadays has become indispensable in the management of pediatric vascular lesions. With a proper balance of wavelength, energy density and pulse duration, the laser energy of thermo coagulation could be molded to effectively manage different lesions. Both dermatology and plastic surgery have been transformed by understanding vascular lesions biology and modern laser technology. As a result, we can now provide an optimal selective treatment with minimal collateral damage. Although alternatives such as the potassium titanyl phosphate (KTP), red/infrared (IR), or intense pulsed light lasers are available, pulsed dye lasers continue to be the standard of care for the majority of pediatric vascular lesions.

Expression and prognostic value of the Ki-67 in Wilms' tumor: experience with 48 cases.

PURPOSE: Ki-67, tumor proliferation marker, is an important prognostic factor in a variety of cancers. In the present study, we investigated the expression and the prognostic value of Ki-67 in nephroblastoma. METHODS: Ki-67 expressions were investigated by immunohistochemistry on paraffin-embedded material in 48 children operated on because of nephroblastoma. Patients were treated according to SIOP protocol. The mean follow-up period was 5.4 years. A proliferation index was obtained by immunohistochemistry using anti-Ki-67 anti-body. RESULTS: The mean Ki-67 proliferation index in the blastemal type was 12.3%, and in the epithelial type, 21.4%. In the anaplastic type, Ki-67 proliferation index was: in the blastemal component 20%, in the stromal 21%, and in the epithelial 31%. In the mixed tumor type, Ki-67 proliferation index was assessed as: in the blastemal component 10%, in the epithelial 33% and in the stromal 31.5%. Proliferation index for the epithelium was significantly higher than those found for the blastema (P = 0.001). A correlation between Ki-67 and tumor stage found proliferation index significantly higher in stages I and II (P = 0.002). CONCLUSION: The results support the conclusion that Ki-67 is a relevant marker for assessing the proliferative activity and tumor cell dynamics of nephroblastoma, but it may not be a good clinical prognostic marker.

Peptide therapy with pentadecapeptide BPC 157 in traumatic nerve injury.

We focused on the healing of rat transected sciatic nerve and improvement made by stable gastric pentadecapeptide BPC 157 (10 microg, 10ng/kg) applied shortly after injury (i) intraperitoneally/intragastrically/locally, at the site of anastomosis, or after (ii) non-anastomozed nerve tubing (7 mm nerve segment resected) directly into the tube. Improvement was shown clinically (autotomy), microscopically/morphometrically and functionally (EMG, one or two months post-injury, walking recovery (sciatic functional index (SFI)) at weekly intervals). BPC 157-rats exhibited faster axonal regeneration: histomorphometrically (improved presentation of neural fascicles, homogeneous regeneration pattern, increased density and size of regenerative fibers, existence of epineural and perineural regeneration, uniform target orientation of regenerative fibers, and higher proportion of neural vs. connective tissue, all fascicles in each nerve showed increased diameter of myelinated fibers, thickness of myelin sheet, number of myelinated fibers per area and myelinated fibers as a percentage of the nerve transected area and the increased blood vessels presentation), electrophysiologically (increased motor action potentials), functionally (improved SFI), the autotomy absent. Thus, BPC 157 markedly improved rat sciatic nerve healing.
