Surgical management of gastroschisis with the use of primary and staged closure based on the department's 20-year experience.

ABSTRACTBACKGROUND: Gastroschisis is a common developmental anomaly of the abdominal front wall. The aim of surgical management is to restore the integrity of the abdominal wall and to insert the bowel into the abdominal cavity with the use of the primary or staged closure technique.The objective of this paper is to analyze our 20-year experience with surgical treatment of gastroschisis with primary and staged closure, to compare the postoperative course for the said techniques as well as to identify factors influencing the course and early results of treatment. METHODS: The research materials consist of a retrospective analysis of medical history of patients treated at the Pediatric Surgery Clinic in Poznan over 20 years period from 2000 to 2019. 59 patients were operated on: 30 girls and 29 boys. RESULTS: Surgical treatment was performed in all the cases. Primary closure was performed in 32% of the cases, whereas staged silo closure was performed in 68% of the cases. Postoperative analgosedation was used for 6 days on average after primary closures, and 13 days on average after staged closures. Generalized bacterial infection was present in 21% of patients treated with primary closures and 37% for staged closures. Infants treated with staged closure began enteral feeding considerably later (day 22) than those treated with primary closure (day 12). CONCLUSIONS: It is not possible to indicate clearly which surgical technique is superior to the other based on the results obtained. When choosing the treatment method, the patient's clinical condition, associated anomalies, and the medical team's experience must be taken into consideration.

The Surgical Procedure in the Case of Ovarian Lesion in Neonate.

BACKGROUND: In newborns and infants, ovarian lesions can be detected during ultrasound examination before or after birth. Malignant ovarian lesions account for <1% of malignancies in newborns. However, in case of doubt about the nature of the lesion, surgery with tissue collection for histopathologic evaluation should be considered with the absolute condition of fertility preservation. OBSERVATIONS: The aim of this publication was to describe a case report of a 3-day-old infant who presented an ovarian lesion on postnatal ultrasound, with features suggesting a malignant nature of the ovary. In the described case, laparoscopy and mini-laparotomy were performed, torsion was excluded. The ovary was preserved, and histopathologic examination excluded the malignant nature of the lesion. CONCLUSION: A detailed analysis of the clinical status, laboratory tests, and imaging studies is necessary before making a final decision on further therapeutic, especially surgical management of a newborn with an ovarian lesion.

Thyroid diseases in children and adolescents requiring surgical treatment-indications, techniques, results, and complications based on 10 years of the single center's own experience.

Introduction: Although thyroid abnormalities are observed less frequently in children than in adults, the increased incidence of thyroid cancer makes it mandatory for all pediatric surgeons to be knowledgeable about the disorders of this gland. Thyroid abnormalities can be associated with hyperthyroidism or hypothyroidism and euthyroidism and/or symmetric or asymmetric enlargement of the gland. Aim: The present study was undertaken to retrospectively analyze the indications, surgical techniques used, results obtained, and complications found in the surgical treatment of thyroid diseases in children and adolescents in a surgical center for the macro-region of western Poland. Methods: The data of 148 patients undergoing total or partial thyroidectomy between 2013 and 2022 were analyzed from the medical records of the Department of Pediatric Surgery, Traumatology, and Urology of the Medical University of Poznan, Poland. Results: A total of 95 children underwent subtotal thyroidectomy and 64 underwent total thyroidectomy, of which the procedure was widened to include prophylactic removal of neck lymph nodes in 45 patients. There were 113 girls (76%) in the analyzed group, and the average age of the patients at the time of surgical treatment was 15 years. The average time from the diagnosis of thyroid disease to surgery was 4 months, ranging from 2 weeks to 3 years. Of the 64 patients undergoing total thyroid resection, 35 (54.69%) were diagnosed with thyroid cancer. Conclusions: Collaboration within a multidisciplinary team ensures optimal surgical outcomes in children and adolescents with thyroid disease. With extreme caution, thyroid removal is a safe procedure with few complications, but the experience of the surgeon performing thyroid surgery in children remains crucial. Despite the absence of such a diagnosis in the first fine-needle aspiration biopsy, the high percentage of thyroid carcinomas in the analyzed group may be because the initial biopsy was performed in a less experienced center, also in terms of histopathological laboratory. Hence, we point out the necessity of performing a repeat fine-needle aspiration biopsy (according to the Bethesda classification) in a more experienced center before the final decision of thyroidectomy.

Testicular and scrotal abnormalities in pediatric and adult patients.

Testicular and scrotal abnormalities can occur in children, adolescents, and adults. The lesions, often accompanied by pain and swelling/enlargement of the scrotum, can cause anxiety in patients and their parents. Regardless of age, proper diagnosis is based on adequate anamnesis and physical examination. Color Doppler ultrasound is the first-line test in the differential process of testicular and scrotal diseases. Testicular and scrotal lesions require differentiation for benign and malignant processes as well as therapeutic management, including urgent surgical intervention. The aim of this paper is to present the most common causes of testicular and scrotal abnormalities in pediatric and adult patients and to outline the symptoms and diagnostic and therapeutic management.

A Rare Case of Dedifferentiated Liposarcoma with Osteosarcomatous Differentiation-Diagnostic and Therapeutic Challenges.

INTRODUCTION: Liposarcomas are the most common of all sarcomas. A well-differentiated liposarcoma can transform into a dedifferentiated liposarcoma with myogenic, osteo- or chondrosarcomatous heterologous differentiation. Genomic amplification of MDM2 gene is then characteristic. Treatment usually involves surgical resection to radically remove the tumor. Other treatments such as chemotherapy and radiotherapy may also be used. CASE REPORT: A 60-year-old patient was admitted to the hospital for surgical treatment of a left renal mass. The true location of the tumor was discovered only intraoperatively. The lesion was completely removed laparoscopically with preservation of the capsule. Genomic amplification of MDM2 gene was confirmed. One and a half years after surgery, despite the removal of the tumor without the surrounding margin of healthy tissue, the patient remains without recurrence. CONCLUSION: Dedifferentiated liposarcoma with osteosarcomatous differentiation is a sporadic case and may occur in various locations of the retroperitoneal space, also mimicking a renal tumor. The laparoscopic technique is a safe surgical treatment for tumors of unclear origin. Removal of dedifferentiated liposarcoma with osteosarcomatous differentiation tumor with preservation of the lesion capsule without maintaining a margin of healthy tissue also allows for long-term cure. Precise immunohistochemical and molecular studies may have an impact on the effectiveness of further treatment and the prognosis of the patient. A patient after surgical treatment of liposarcoma requires constant outpatient follow-up for the reason of the high risk of local and distant recurrence.

Ileal pouch-anal anastomosis in paediatric age group: perioperative period, functional outcome and patient satisfaction.

<b> Introduction: </b> Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is a procedure which enables reconstruction of the continuity of the gastrointestinal track after resection of the large intestine and rectum. The most common diseases that require this type of resection include: ulcerative colitis and familial adenomatous polyposis. </br></br> <b>Aim:</b> The study aimed to determine the effectiveness of IPAA in the surgical treatment of the paediatric age group. </br></br> <b>Material and methods:</b> The research material was collected based on medical records of 21 patients who underwent proctocolectomy at the Department of Pediatric Surgery, Traumatology, and Urology of the Medical University of Poznan in 2000-2021. </br></br> <b>Results: </b> In a group of 21 patients, 11 children were qualified for proctocolectomy due to ulcerative colitis (UC), 6 due to familial adenomatous polyposis (FAP), 3 due to Hirschsprung's disease (HD), and one child due to Crohn's disease (CD). Early complications in treated patients included dehiscence of the postoperative wound, bleeding from the lower gastrointestinal tract and anastomotic leakage. Late complications included pouchitis, stenosis of the ileostomy, narrowing of the anastomotic site and soiling. Quality of life was rated at an average of 9-10 by 16 patients on a scale of 1-10. </br></br> <b>Conclusions:</b> IPAA is a proven method of reconstruction for the paediatric age group requiring proctocolectomy. Complications are common, most often related to the underlying disease and the clinical condition of the patients. Despite possible complications, patients rate their quality of life high on the scale. Each qualification for surgery should be carried out in a multidisciplinary team.

Are There Any Limiting Factors of Minimally Invasive Adrenalectomy in Children? Over 20-Year Single-Center Experience.

<b> Introduction:</b> Laparoscopic adrenalectomy is more widely recognized as a valuable treatment method for benign and malignant tumours. </br></br> <b>Aim:</b> This study reviews over 20-year experience with laparoscopic adrenalectomy in children in Central-West Poland. </br></br> <b>Materials and methods:</b> During the last 21 years, 5041 laparoscopic procedures were performed, among them 39 adrenalectomies in children aged from 2 days to 17 years. The following data were analysed: patient's age at diagnosis and surgery, lesion volume in CT/MRI examination, duration of surgery, the incidence of complication after surgery, and length of hospitalization. </br></br> <b>Results:</b> The volume of adrenal lesion visualized by CT or MRI before surgery varied from 0.5 cm3 up to 490 cm3, with a median of 14 cm3. As many as 80% of adrenalectomies allowed radical removal of the lesion and 92% of those procedures were performed without any complications. From all data analysed, only age, both at diagnosis and at surgery, was significantly lower in patients with a malignant lesion. </br></br> <b>Conclusions:</b> Laparoscopic adrenalectomy is a valuable method to use in paediatric patients for both benign and malignant adrenal lesions. However, in patients with malignant adrenal lesions it may be expected that the procedure will be more difficult due to the lower age and larger lesion size.

Why Is Health Care for Children with Down Syndrome So Crucial from the First Days of Life? A Retrospective Cohort Study Emphasized Transient Abnormal Myelopoiesis (TAM) Syndrome at Three Centers.

Down syndrome (DS) is a common genetic disorder and is associated with an increased likelihood of many diseases, including defects of the heart, genitourinary system, gastrointestinal tract, and oncological diseases. The aim of this study was to analyze medical problems occurring in newborns with DS and to create a basic diagnostic and therapeutic algorithm intended primarily for neonatologists, pediatricians, family physicians, and physicians of other specialties caring for children with DS. Over a 5-year period, the medical records of 161 neonates with Down syndrome from four neonatology departments in Poznan, Poland, were examined. After applying exclusion criteria, 111 patients were analyzed. Data obtained from medical history included sex, week of gestation, birth weight, APGAR score, clinical symptoms, peripheral blood count with smear, and clinical features such as jaundice, hemorrhagic diathesis, ascites, hepato- or splenomegaly, pericardial or pleural effusion, respiratory failure, and other rare transient signs of abnormal myelopoiesis: fetal edema, hepatic fibrosis, renal failure, and rush. In the study group, 8% of children with Down syndrome were diagnosed with a heart and 1.8% with a genitourinary defect. Transient abnormal myelopoiesis syndrome (Transient abnormal myelopoiesis (TAM)) was found in 10% of newborns with DS. A blood count with blood smear, cardiology consultation with echocardiography, and an abdominal ultrasound should be performed in the first few days after birth in all newborns with Down syndrome. If this is not possible and the child's condition is stable, these tests can be performed within 2-3 months after birth.

Diagnosis and treatment of thyroid cancer in adult patients - Recommendations of Polish Scientific Societies and the National Oncological Strategy. 2022 Update [Diagnostyka i leczenie raka tarczycy u chorych doroslych - Rekomendacje Polskich Towarzystw Naukowych oraz Narodowej Strategii Onkologicznej. Aktualizacja na rok 2022].

The guidelines Thyroid Cancer 2022 are prepared based on previous Polish recommendations updated in 2018. They consider international guidelines - American Thyroid Association (ATA) 2015 and National Comprehensive Cancer Network (NCCN); however, they are adapted according to the ADAPTE process. The strength of the recommendations and the quality of the scientific evidence are assessed according to the GRADE system and the ATA 2015 and NCCN recommendations. The core of the changes made in the Polish recommendations is the inclusion of international guidelines and the results of those scientific studies that have already proven themselves prospectively. These extensions allow de-escalation of the therapeutic management in low-risk thyroid carcinoma, i.e., enabling active surveillance in papillary microcarcinoma to be chosen alternatively to minimally invasive techniques after agreeing on such management with the patient. Further extensions allow the use of thyroid lobectomy with the isthmus (hemithyroidectomy) in low-risk cancer up to 2 cm in diameter, modification of the indications for postoperative radioiodine treatment toward personalized approach, and clarification of the criteria used during postoperative L-thyroxine treatment. At the same time, the criteria for the preoperative differential diagnosis of nodular goiter in terms of ultrasonography and fine-needle aspiration biopsy have been clarified, and the rules for the histopathological examination of postoperative thyroid material have been updated. New, updated rules for monitoring patients after treatment are also presented. The updated recommendations focus on ensuring the best possible quality of life after thyroid cancer treatment while maintaining the good efficacy of this treatment.

Diagnostics and treatment of complications of SARS-CoV-2 infection in the pediatric surgery department. An analysis based on seven clinical cases and literature review.

<b> Introduction:</b> Pediatric inflammatory multisystem syndrome - temporally associated with SARS-CoV-2 (PIMS-TS) is a new disease, the first cases of which were observed in the spring of 2020. It affects children who have been infected with SARS-CoV-2 virus (severe acute respiratory syndrome coronavirus 2) and children who have been in direct contact with patients suffering from COVID-19 (coronavirus disease 2019). The disease is characterized by a wide spectrum of symptoms and the development of generalized inflammation of different organs and systems. One of the numerous symptoms may be severe abdominal pain. </br></br> <b>Aim:</b> The aim of this study was to review the available literature and analyze the results of patients treated at the Department of Pediatric Surgery, Traumatology and Urology in Poznan in whom PIMS-TS imitated acute surgical abdominal disease. </br></br> <b>Materials and methods:</b> material for the study was collected on the basis of medical records of patients treated at the Department of Pediatric Surgery, Traumatology and Urology of the Poznan University of Medical Sciences in the period between March 2020 and February 2021. </br></br> <b>Results:</b> TDuring this period, seven patients met the PIMS-TS criteria and three children were qualified for surgical treatment. Only one patient had an acute surgical cause of abdominal pain. </br></br> <b>Discussions:</b> The guidelines of the expert group at the Polish Pediatric Society and the National Consultant in the field of Pediatrics indicate the need to exclude acute surgical abdominal disease as a criterion for the diagnosis of PIMS-TS syndrome. In patients with acute abdominal pain, imaging and laboratory tests are sometimes diagnostically inconclusive, therefore exploratory laparoscopy is worth considering in order to differentiate PIMS-TS from acute surgical abdominal disease.

How to Treat a Child With a Concurrent Diagnosis of Leukemia and Generalized Mucormycosis? Case Report.

Mucormycosis is a rare but a devastating and lifethreatening fungal infection caused by fungi of the order Mucorales usually in immunocompromised patients. Depending on the organs and tissues involved, there are sinus, pulmonary, gastrointestinal, orbital, cerebral, cutaneous and disseminated mucormycosis. Only sporadic cases of hepatic mucormycosis have been described. Hence, we present a complicated treatment management in a 16-month-old child with leukemia and generalized mucormycosis localized in the liver and in the gastrointestinal tract. The collaboration of a multidisciplinary team and appropriate therapy gave a chance not only to save the patient's life, but to carry out anticancer treatment, which resulted in leukemia remission. A 6-month course of isavuconazole and amphotericin B liposomal as well as surgical treatment led to the cure of the fungal infection.

Clinical, Histological, Cytogenetic and Molecular Analysis of Monozygous Twins with Wilms Tumor.

The familial occurrence of childhood cancers has been proven for a long time. Wilms' tumors often do not have a clear germline genetic cause. However, approximately 2% of all nephroblastoma cases are familial. Descriptions of twins with the same cancer are extremely rare, so our aim was to present the background of the available literature of the occurrence of Wilms' tumor in a pair of monozygotic twin girls with detailed clinical, histological, and molecular analysis. Two twins were born of unrelated Caucasian parents. Family history revealed no known chronic diseases or malformations. At the age of 3.5 years, the first twin was admitted to the emergency department due to hematuria and abdominal pain. Ultrasound examination revealed an enlarged right kidney, 12.8 cm, with a mass in the upper pole measuring 56 × 69 × 78 mm. The second girl was referred for an abdominal ultrasound, which revealed a right kidney measuring 8.6 cm with a central mass measuring 54 × 45 × 41 mm. Both children underwent surgical resection, and the histopathological result showed a mixed form of nephroblastoma, predominantly epithelioid with residual blastemal compartment. Detailed clinical, histological, cytogenetic, and molecular analyses were performed on both sisters. It was also decided to identify environmental factors. Information was obtained that the girls' parents run a farm and regularly use pesticides and chemical rodenticides. Based on our observations and the available literature, Wilms tumor in monozygotic twins may be present. Both genetic and environmental factors may be involved in the development of tumors. After excluding methylation abnormalities and mutations in the genes studied, we questioned whether the onset of Wilms tumor in both sisters could be the result of exposure of the twins' parents to pesticides.

Profile of Girls With Adnexal Torsion: Single Center Experience.

OBJECTIVE: To compare features of pre-menarchal and post-menarchal patients with adnexal torsion. METHODS: We reviewed hospital records to note examination findings, laboratory work-up, imaging results, operative findings and course during hospital stay for 56 girls aged from 7 days to 17 years with adnexal torsion presenting between January, 2012 and December, 2020. RESULTS: 31 girls were pre-menarchal. Pain was the most common symptom. There were significant differences in the volume of the ovary visualized in ultrasound in amenorrheic and menstruating girls [median (IQR) 78234 (39600, 183600) mm3 vs 243432 (158661, 388800) mm3; P=0.004]. Pain was the most common symptom. Over the years, there was an increase in laparoscopic procedures, and efforts to preserve the ovary after the torsion. CONCLUSIONS: The differential diagnosis in the case of abdominal pain should include adnexal torsion both in non-menstruating and menstruating girls.

The management of pediatric patient with head injury in an adult-oriented Emergency Department.

INTRODUCTION: The aim of the work is to present the possible struggles that a doctor of the Hospital Emergency Department for adults may encounter when admitting a pediatric patient with a head injury. Head trauma is the most common cause of death or permanent injury in the pediatric population. The lack of experience in dealing with a minor patient, as well as the lack of knowledge of anatomical and physiological differences make it necessary to introduce simple algorithms. It helps to facilitate decision-making proces while facing this challange. METHODS: The paper discusses the recommended management of a pediatric patient with the head injury treated by a team with limited experience in the field, based on a review of the literature - available studies and publications from the last 15 years - as well as the authors own experience. RESULT: In case of the pediatric head trauma there is a need to develop a patient examination scheme, paying attention to the specific anatomical and physiological differences resulting from the patient's age. It i salso recommended to introduce an algorithm that allows to limit and reasonably use imagining mostly CT scan in pediatric patients ( CHALICE, CATCH and PECARN algorithms). The article also recommends methods of management in the case of particular types of craniocerebral trauma.

Liver biopsies in children indications, techniques, results and complications. A single-centre study.

INTRODUCTION: Liver biopsy is a safe and helpful diagnostic tool for many liver disorders. It can be performed using various techniques. Regardless of the technique, the liver biopsy is considered to be a safe procedure. AIM OF THE STUDY: We aimed to analyze the indications, techniques, results, and complications of liver biopsies in the paediatric age group. MATERIAL AND METHODS: We retrospectively obtained the data from the medical history records of 63 paediatric patients who underwent the liver biopsy. The data were analyzed statistically. RESULTS: The most often performed type of biopsy was core needle biopsy (tru-cut), followed by core needle aspiration biopsy, fine-needle aspiration biopsy, open biopsy, and laparoscopic biopsy. Complications in the form of hematoma occurred only in 2 cases. The most common indications for the procedure were viral hepatitis monitoring/diagnosis, focal lesions, and autoimmune hepatitis. The histopathological results were predominantly hepatitis (viral and non-viral) and neoplasm. CONCLUSIONS: Liver biopsy is a safe procedure regardless of the technique used to obtain a tissue sample. Therefore, it should not be avoided when it is indicated.

Clinically Malignant Breast Lesion in an Adolescent Girl: A Case Report.

Diseases of the breast in adolescent women are usually benign, and their treatment is simple using appropriate medical strategy and rarely surgical therapy. The whole team's real challenge is when the girl presents malignant breast cancer symptoms such as a non-movable tumor, nipple discharge, nipple retraction, retraction of the skin, inflammatory infiltration of the breast, or ulceration. Presented here is a case of a 15-years-old girl with the features of a malignant neoplasm of the breast. There was an observed non-movable tumor, retraction of the nipple, inflammatory infiltration, and pain. The performed ultrasound and magnetic resonance imaging suggested a malignant lesion measuring 84 mm × 66 mm × 50 mm. After many diagnostic difficulties, the lesion evacuated spontaneously, and the abscess was diagnosed. In conclusion, not all features of a malignant breast tumor in adult women are typical for adolescent females. In young girls, breast diseases are usually benign, and appropriate diagnostics and therapy allow for an effective cure. Atypical breast lesions require the extraordinary cooperation of a multidisciplinary team.

Arterial constriction after resection of neuroblastic tumors in children: Two-center retrospective study.

BACKGROUND/PURPOSE: Neuroblastic tumors are the most common pediatric extracranial solid tumors in infants and very young children. Although, especially in newborns, there is an increasing number of situations in which observation alone is used, surgery remains an important step in the treatment of neuroblastoma but can be complicated by arterial vasospasm in the surgical field. The aim of this two-center retrospective study was to analyze the occurrence of arterial constriction as a complication of neuroblastic tumors resection. METHODS: Medical records of patients who were treated surgically for neuroblastic tumors in the years 2012-2019 were reviewed. RESULTS: For 8 years, 113 children were treated for neuroblastic tumors. The treatment included both primary and delayed surgery after initial chemotherapy carried out according to SIOPEN protocols. In 11 out of 113 cases (9.7%) local arterial constriction was observed. In 6 out of 11 cases an attempt was made to save the organ, however, two patients suffered from kidney atrophy, two other partial kidney infarctions, one child suffered from partial limb paresis, and another from brain ischemia and death. CONCLUSIONS: Local arterial constriction constitutes a relatively common (10% of cases) and severe complication of neuroblastic tumors resection. Efficacy of local application of papaverine based on our experience remains unproven hence further research is warranted.

Evaluation of the activity and medical nutrition therapy types used by nutrition support teams in hospitals in the Greater Poland voivodeship.

INTRODUCTION: Nutrition therapy is medical treatment that includes assessment of patients' nutritional status, their nutrient requirements, supply of nutritional products in appropriate quantities, and monitoring all of these processes. The nutrition support team is responsible for the organization of the nutrition therapy. AIM: To evaluate the activity of nutrition support teams in hospitals in the Greater Poland voivodeship. MATERIAL AND METHODS: An evaluation of nutrition support teams' activity and the types of nutrition therapy used in hospitals in the Greater Poland voivodeship was made. In order to collect all the necessary data, a questionnaire with closed-ended questions was sent to all hospitals registered in the voivodeship. RESULTS: Out of 25 hospitals that returned the completed questionnaire, 15 (60.0%) confirmed the presence of a nutrition support team in their structures. In previous reports it was 17 centres (68.0%) that had such team, but sometimes the team was not working to its full extent. 73.0% of hospitals were satisfied with both the presence of the team and its activity concerning proper fulfilment of entrusted tasks. The activity of nutrition support teams in the Greater Poland voivodeship correlated closely with the size of the hospital. CONCLUSIONS: Nutrition support teams function in the majority of hospitals in the Greater Poland voivodeship. Nutrition teams are more common in larger hospitals. In order to provide proper medical nutrition therapy, the legal obligation to appoint nutrition support teams in the hospitals should be restored.

The Important Role of the Radiologist in Determining the Indications for the Surgical Treatment of Neuroblastoma with Vascular Image-Defined Risk Factors: A Case Report.

The International Neuroblastoma Risk Group Staging System (INRGSS) is based on the age of patients and preoperative imaging, with attention paid to whether the primary tumor is affected by one or more of specific image-defined risk factors (IDRFs). This publication presents a 2.5-year-old boy with neuroblastoma who had an accidental ligation of the celiac trunk during tumor resection. The consequences of this complication were pancreatic and spleen ischemia and necrosis, ischemia, and perforation of the common bile duct, gallbladder, stomach, and duodenum. The aim of this publication was to highlight the great role of the radiologist in determining the indications for neuroblastoma tumor removal, especially with current vascular IDRFs, and to show how the radiologist's insightful approach can save the patient from irreversible complications.

Simultaneous Occurrence of Choriocarcinoma in an Infant and Mother.

Infantile choriocarcinoma is an extremely rare disease. We present a case study of a 1-month-old male with choriocarcinoma diagnosed simultaneously with his mother. On admission to hospital, the disease was very advanced and massive progression and multi-organ failure caused the death of the patient despite the implemented treatment. It was too late to save the child's life, but early enough to save his mother. The authors believe that the serum levels of hCG should be determined in every newborn with anemia and liver tumor, especially when the mother has a positive history of miscarriage.
