Orbital cellulitis is an uncommon condition with risks to sight and life. As a complication of maxillofacial injuries, the literature suggests this is only possible with fractures or direct inoculation, and there are no reports to the contrary. Here, we make the first report of a possible etiology by which orbital cellulitis developed in a 14-year-old boy even without skin breach or bony fractures; as well as a rare causative pathogen. He presented with facial abscess and progressive orbital cellulitis after blunt facial trauma, requiring functional endoscopic sinus surgery with needle aspiration of facial abscess externally. Cultures showed growth of Streptococcus constellatus/Parvimonas micra, and he received further antibiotics with full recovery. The pathophysiology of orbital cellulitis in this patient is attributed to vascular congestion and local pressure from maxillofacial contusion and maxillary hemoantrum, with impaired paranasal sinus ventilation encouraging anaerobic bacterial growth. Further progression led to facial abscess formation and intraorbital spread with orbital cellulitis. The pediatric demographic is injury-prone, and self-reporting of symptoms can be delayed. Hence, increased suspicion of complicated injuries and orbital cellulitis may be required when managing maxillofacial contusions so that prompt treatment can be given.

A randomized comparison of ultrasound (US)-guided core needle biopsy (CNB) under the assistance of hydrodissection with fine needle aspiration (FNA) was performed to evaluate the feasibility, safety and effectiveness for the diagnosis of high-risk cervical lymph nodes. Patients from December 2018 to May 2020 were randomly assigned to the CNB group and the FNA group at a ratio of 1:1. This study protocol was approved by the Ethics Committee of our hospital and registered in the Chinese Clinical Trial Registry (ChiCTR1800019370). The feasibility of CNB for high-risk cervical lymph nodes was evaluated by observing and recording the separation success rate (SSR) and technical success rate (TSR) of the CNB group. Safety was evaluated by comparing the incidence of major complications in the two groups. The diagnostic efficacy was evaluated by comparing the diagnostic accuracy, sensitivity, and specificity of the two groups. A total of 84 patients (84 lymph nodes) were randomized into the CNB (n = 42) and FNA (n = 42) groups. All patients in the CNB group achieved successful hydrodissection and biopsy. The SSR and TSR were both 100% in the CNB group. There were no major complications during or after the process in the two groups. Compared with the FNA group, the CNB group was significantly superior in terms of diagnostic accuracy and sensitivity (100% vs. 81.0%, P = 0.009; 100% vs. 79.2%, P = 0.035, respectively). The specificity of the two groups was 100%, and there was no significant difference. Compared with FNA, CNB under the assistance of hydrodissection is a feasible and safe method but is more effective for the diagnosis of high-risk cervical lymph nodes.Clinical Trial Registration, ChiCTR1800019370.

Background: Tuberculosis (TB) is one of the most important infectious diseases worldwide. Bacillus Calmette-Guerin (BCG) is a live attenuated vaccine, entered into the childhood immunization program by the World Health Organization (WHO) in 1974 to prevent TB. One of the relatively common complications of BCG vaccination is regional lymphadenitis. Objectives: This study aimed to determine the lymphadenitis incidence in BCG-vaccinated children in southwest Iran. Methods: In a prospective descriptive study, infants born from March to June 2017 were evaluated for BCG vaccine complications at two, four, six, nine, and 12 months of age in Ahvaz, southwestern Iran. Results: The study enrolled 1,506 infants (794 males and 712 females). Among the vaccinated infants, four (0.26%) had injection site reactions, and 106 (7.03%) presented lymphadenitis (66 males and 40 females). The lymphadenitis rate was significantly higher in males than in females (P = 0.024). The mean age at presentation was 4.28 ± 0.79 months. Suppurative lymphadenitis was seen in 53 (50%) cases and nonsuppurative lymphadenitis in 53 (50%) cases. About 80% of nonsuppurative lymphadenitis resolved entirely or partially after a one-year follow-up. Of 53 cases with suppurative lymphadenitis, 46 (43.4%) developed spontaneous drainage, and seven (6.6%) were drained by needle aspiration. No significant relationship was found between the BCG inoculation site and lymphadenitis rate. No other complications such as osteomyelitis or disseminated BCG infection were observed after one year of follow-up. Conclusions: The relatively high incidence of BCG lymphadenitis in this study may be due to the vaccine strain, young vaccinees, and improper vaccination techniques. In most cases, nonsuppurative lymphadenitis regressed spontaneously, and suppurative lymphadenitis was drained spontaneously or by needle aspiration.

Many clinicians increasingly use dry needling in clinical practice. However, whether patients’ intake of antithrombotic drugs should be considered as a contraindication for dry needling has not been investigated to date. As far as we know, there are no publications in analyzing the intake of antiplatelet or anticoagulant agents in the context of dry needling techniques. A thorough analysis of existing medications and how they may impact various needling approaches may contribute to improved evidence-informed clinical practice. The primary purpose of this paper is to review the current knowledge of antithrombotic therapy in the context of dry needling. In addition, reviewing guidelines of other needling approaches, such as electromyography, acupuncture, botulinum toxin infiltration, and neck ultrasound-guided fine-needle aspiration biopsy, may provide specific insights relevant for dry needling. Based on published data, taking antithrombotic medication should not be considered an absolute contraindication for dry needling techniques. As long as specific dry needling and individual risks are properly considered, it does not change the risk and safety profile of dry needling. Under specific circumstances, the use of ultrasound guidance is recommended when available.

AbstractThe etiology of solid retroperitoneal mass may be autoimmune or neoplastic and should be investigated by imaging and histology. The spectrum of differential diagnoses includes retroperitoneal fibrosis and retroperitoneal tumors. As treatment for these entities differs substantially, early and accurate diagnosis is essential. We present a case of a 54-year-old woman admitted to our hospital with stroke-like symptoms. Suspecting vasculitis, magnetic resonance imaging of the head and abdomen was performed, which revealed circular enhancement of the internal carotid artery as well as retroperitoneal and periaortic masses. In light of the radiographic findings, an autoimmune process, such as retroperitoneal fibrosis, was hypothesized. Steroid treatment was initiated but did not lead to significant remission. Re-evaluation of the mass with fine-needle aspiration did not show malignant cells while diagnostic surgery and histological assessment revealed neoplastic lymphoproliferation. The final diagnosis was a non-Hodgkin B-cell lymphoma. Chemo- and immunotherapy were initiated. Follow-up abdominal computed tomography revealed significant remission of the retroperitoneal mass. Initially, the retroperitoneal mass was highly suspicious for RF. While imaging can be useful, obtaining histology should always be considered when there is an uncertain clinical presentation. Without histology, we would have missed a non-Hodgkin B-cell lymphoma in this case. Minimally invasive techniques such as fine-needle aspiration may be practical but can give false-negative results.

Objectives: Bone is a frequent site of metastases and typically indicates a short-term prognosis in cancer patients. The majority of skeletal metastases are due to breast and prostate cancer. Bone metastasis is actually much more common than primary bone cancers, especially in adults. Fine-needle aspiration cytology (FNAC) provides reasonably accurate pre-operative diagnosis in vast majority of cases. This study aims to elicit the cytomorphological detail of various metastatic bone tumors. Material and Methods: A total of 109 cases of tumors metastatic to bone have been included in this study. The details of the cases were available from the archives of the department of cytology. May Grunwald Giemsa and hematoxylin and eosin stained smears were studied and examined for the cytomorphological spectrum. Cell block and immunohistochemistry tests were done, wherever feasible. Results: Among 109 patients, the mean age was 54.52 years. There was male preponderance with 90 males and 19 females. The most common site of metastases was in the vertebra (82 cases), and 76 cases were in the dorsolumbar region. The most common type of tumor metastasizing was adenocarcinoma. Conclusion: FNAC is a very useful, economical procedure. There are characteristic cytological features of the metastatic lesions and the basic diagnostic categorization of the malignant tumors is possible on FNAC. Regarding the primary source clinical history, radiological features of the primary tumor, if any, and immunocytochemistry may be needed.

Abstract Introduction Thyroid dysfunctions associated with SARS-CoV-2 are emerging in scientific literature. During the second COVID-19 epidemic spread, we evaluated a patient with the suspect of subacute thyroiditis. Methods and results Specimen from fine-needle aspiration of a hypoechoic undefined area was analyzed for cytology and for SARS-CoV-2 detection. SARS-CoV-2 was retrieved by real-time polymerase chain reaction on the cytologic sample, which was then cultured on Vero E6 cells and demonstrated to be cytopathic. Whole-genome sequence was deposited. Histological exam diagnosed a rare case of primary thyroid sarcoma with diffuse and strong expression of mouse double minute 2 homolog (MDM2) oncoprotein. Ultrastructural examination confirmed, in several neoplastic cells, the presence of viral particles in cytoplasmic vacuoles. Conclusions In our hypothesis, SARS-CoV-2 and sarcoma coexistence could represent a synergistic interplay, ultimately favoring both viral persistence and tumor proliferation: the overexpression of MDM2 in tumor cells might have generated a favorable immunological niche for SARS-CoV-2 localization and, in turn, SARS-CoV-2 could have favored tumor growth by inducing MDM2-mediated p53 downregulation. Functional studies are needed to confirm this suggestive pathway.
