To compare features of pre-menarchal and post-menarchal patients with adnexal torsion.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, 2020.31 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.The differential diagnosis in the case of abdominal pain should include adnexal torsion both in non-menstruating and menstruating girls.

Embryonal rhabdomyosarcoma, a malignant soft tissue neoplasm, is 1 of the most common pediatric tumors of the vagina. Although radical surgery has been replaced with radiation therapy, chemotherapy, and conservative surgery, the use of vaginoscopy is still uncommon. We present the case of an infant who underwent vaginoscopic resection because of botryoid sarcoma at 9 months of age.

In inflammatory bowel diseases (IBD) diarrhea can be caused by exacerbation and/or infectious agents. Fecal calprotectin (FC) is a well-established biomarker of intestinal inflammation in IBD. However, its usefulness in depiction of IBD exacerbation from infectious diarrhea is limited. The value of fecal pyruvate kinase isoenzyme type 2 (M2-PK) in this application remains unknown.To compare the performance of M2-PK and FC in discriminating between diarrhea caused by IBD and infectious agents.One hundred three patients were enrolled for the study, including 32 with ulcerative colitis (UC), 21 with Crohn's disease (CD), 29 with acute diarrhea caused by rotavirus (AD-RV), and 21 with acute diarrhea caused by Salmonella enteritidis (AD-SE). M2-PK and FC were measured using ELISA. Areas under receiver operating characteristic curves (AUCs), sensitivities and specificities for both tests in distinguishing between patient subgroups with moderate to severe UC and CD from AD-RV and AD-SE were calculated.Differences in AUCs between M2-PK and FC for distinguishing UC [CD] from AD-RV were -0.06 (p0.028) [-0.10 (p0.0018)] and for differentiating UC [CD] from AD-SE were 0.03 (NS) [-0.19(p0.0011)].M2-PK sensitivities and specificities in distinguishing UC [CD] from AD-RV were 75.0%[71.4%] and 89.7% [89.7%] and for differentiation of UC [CD] from AD-SE were 56.3% [71.4%] and 95.2[57.1%].The performance of M2-PK in distinguishing between children with moderate-to-severe IBD and patients with infectious gastroenteritis was inferior to FC. Neither test had sensitivity ands pecificity sufficient for everyday clinical application.

Study design Polish adaptation of the original version of Scoliosis Research Society (SRS) instrument. Objective The transcultural adaptation of SRS-22 and evaluation of its internal consistency. Summary of background data High psychometric value of the SRS-22 Questionnaire has made it an effective evaluation instrument in clinically assessing the functional status of patients with adolescent idiopathic scoliosis. Methods First, 2 translators translated the original version into Polish. Afterwards, the translators identified differences between the translations and produced a consensus version. In the third stage, 2 native English speakers produced back translations. Finally, a team of 2 orthopedic surgeons, translators, a statistician and a psychologist reviewed all the translations to produce a prefinal version. The questionnaire was administered to 60 girls at the age of 16.6, SD 2.0 with adolescent idiopathic scoliosis treated with the Cotrel-Dubousset method in Pediatric Orthopaedics and Traumatology Clinic in Poznan. Results The internal consistency in the Polish version equaled 0.89 for the overall result and 0.81 for function, 0.81 for pain, 0.80 for mental health, 0.77 for self-image, and 0.69 for treatment satisfaction domains, respectively. Conclusion The Polish version of SRS-22 is characterized by high internal consistency for all domains and for the overall score, which makes it an evaluation tool after surgical treatment compatible with the original SRS-22.

Background: Pediatric hemangiopericytoma (HPC) is an extremely rare vascular tumor with little data available on its clinical course and management. Methods: Fourteen children with HPC registered in Polish Pediatric Rare Tumors and Polish Pediatric Soft-tissue Sarcomas Studies between 1992 and 2002 are reported. Results: Seven patients (F/M: 5/2, age 2–10 months) had infantile HPC, four of whom had primary tumors affecting superficial tissues of the trunk and upper limbs. No child had initial nodal or organ metastases. Primary excision (PE) was performed only in three patients with superficial lesions. They received no supplemental treatment. The remaining four children responded well to chemotherapy (CHT), entering complete remission after CHT alone (n= 2) or after delayed resection (n= 2). No relapses occurred and all patients were alive 48–146 months after treatment. Seven patients (F/M: 2/5, age 3.2–16.5 years) had adult-type HPC, five of whom had tumors localized in superficial tissues of the lower limbs or head/neck. All patients presented with locally advanced disease. PE was performed in five children (complete in four); all patients were alive at follow up of 40–127 months. Three patients died of recurrence after incomplete PE despite supplemental chemo- and radiotherapy. Conclusions: Complete surgical excision remains the mainstay of treatment for both HPC types. In unresectable adult-type HPC adjuvant chemo- and radiotherapy should be administered in macro- and microscopic tumor residues, but the prognosis is poor despite supplemental treatment. High chemo-responsiveness of infantile-type HPC produces a favorable outcome even in cases of unresectable, life-threatening tumors.
