Purpose: The aim of this study is to investigate the optimal treatment for lymphangioma in children by analyzing the effectiveness and complications of treatment modalities.
Methods: We reviewed 128 patients with lymphangioma treated at our institution between 1979 and 2005. Periods of treatment were divided arbitrarily into 2 groups: period I, from 1979 to 1988 (n = 53); and period II, from 1989 to 2005 (n = 75). According to radiological appearance, patients were grouped into 4 types: single cystic (SI; n = 23), macrocystic (MA; n = 11), microcystic (MI; n = 69), and cavernous (CA; n = 25).
Results: Sclerotherapy as primary treatment was performed in only 2 patients (3.8%) in period I using bleomycin but increased significantly in period II to 48 patients (64.0%) using OK-432 (P < .01). Nevertheless, primary surgical excision (69/78 patients, 88.5%) was significantly more successful than sclerotherapy (32/50, 64.0%) (P < .01). The following are the locations and types of lesions: head/neck (n = 69; SI, 11; MA, 5; MI, 42; CA, 11), trunk (n = 34; SI, 6; MA, 6; MI, 15; CA, 7), and extremities/other (n = 25; SI, 6; MI, 12; CA, 7). The effectiveness of sclerotherapy in SI, MA, MI, and CA types was 90.9%, 100%, 68.0%, and 10.0%, respectively. Seventeen patients (SI, 1; MI, 8; CA, 8) who received primary sclerotherapy required surgical excision with good outcome. Complications after primary surgical excision were more serious compared with sclerotherapy.
Conclusion: Sclerotherapy with OK-432 was not as effective as reported in the literature. We recommend OK-432 injection therapy alone for SI and MA types and surgical excision after pretreatment with OK-432 for MI and CA types.

Determination of adequate bony resection margins in inflammatory jaw pathologies using SPECT-CT in primary mandibular reconstruction with virtually planned vascularized bone flaps.
Clin Oral Investig

Department of Oral and Maxillofacial Surgery, University Hospital RWTH Aachen, Pauwelsstraße 30, D-52074, Aachen, Germany.
Objectives: In advanced stages of osteoradionecrosis, medication-related osteonecrosis of the jaw, and osteomyelitis, a resection of sections of the mandible may be unavoidable. The determination of adequate bony resection margins is a fundamental problem because bony resection margins cannot be secured intraoperatively. Single-photon emission computed tomography (SPECT-CT) is more accurate than conventional imaging techniques in detecting inflammatory jaw pathologies.

Methods: Consecutive MRI examinations of patients undergoing RALP for PCa were retrospectively collected from two medical institutions. Patients from center 1 undergoing RALP between January 2020 and December 2021 were included in the derivation cohort and those between January 2022 and December 2022 were allocated to the validation cohort.
Evidence-Based Surgical Guidelines for Treating Children With Rhabdomyosarcoma.
Pediatr Blood Cancer
January 2025
Department of Pediatric Surgery, Pediatric Oncology Institute - GRAACC - Federal University of São Paulo, São Paulo, Brazil.
Background: Surgery remains the cornerstone of treatment for rhabdomyosarcoma (RMS) in children. However, there is considerable variation in surgical management practices worldwide, highlighting the need for standardized Clinical Practice Guidelines (CPG).
Methods: The CPG development involved assembling a multidisciplinary group, prioritizing 10 key topic areas, conducting evidence searches, and synthesizing findings.
Intraoperative methylene blue staining is effective as a single mapping technique in the identification of sentinel lymph nodes in dogs with low-grade mast cell tumours.
J Small Anim Pract

Department of Veterinary Medical Sciences, University of Bologna, Bologna, Italy.
Objectives: The aim of this prospective study was to assess the association between methylene blue staining pattern and the presence of histologic nodal metastasis in dogs with low-grade mast cell tumour in low-resource settings for the efficient diagnosis of lymphatic spread.
Methods: Dogs with a single, cytologically low-grade mast cell tumour and no documented distant metastases were prospectively included and underwent surgery. Along with primary mast cell tumour removal, intraoperative sentinel lymph node mapping with peritumoral mast cell tumour injection and regional lymph node excision, regardless of whether blue dye was visible in the lymph node, were performed.
Zinner syndrome unveiled: Ectopic ureter and seminal vesicle cyst leading to urinary dysfunction: A case report.
Radiol Case Rep

Department of Radiology, Makassed hospital, Jerusalem, Palestine.
Zinner syndrome (ZS) is a rare congenital urological condition characterized by a triad of ipsilateral seminal vesicle cysts, unilateral renal agenesis, and ejaculatory duct obstruction, first described in 1914. This case report details the presentation and management of a 27-year-old male diagnosed with ZS following a 2-month history of urinary frequency, hesitancy, dysuria, and painful ejaculation. Physical examination revealed a left lower abdominal mass, and imaging confirmed the classic findings of ZS, including unilateral renal agenesis, an enlarged seminal vesicle cyst, and an ectopic ureter.
