Clinical Observation and Value Analysis of Endovascular Interventional Therapy for Intracranial Venous Sinus Thrombosis.

Biomed Res Int 2022 14;2022:4931210. Epub 2022 Jun 14.

Department of Neurosurgery, Wuxi People's Hospital Affiliated to Nanjing Medical University, Wuxi, Jiangsu, China.

The main aim of this study was to investigate the therapeutic effect of endovascular interventional therapy on cerebral venous sinus thrombosis (CVST). 137 patients with CVST were included, 92 patients were treated with interventional therapy, and 45 patients were treated with conventional anticoagulant therapy. Through endovascular therapy (EVT) combined with therapy, the patients were treated with EVT in combination with conventional anticoagulant therapy, and the prognosis of the two groups of patients was evaluated.

Direct intracranial invasion of eccrine spiradenocarcinoma of the scalp: a case report and literature review.

BMC Neurol 2022 Jun 18;22(1):223. Epub 2022 Jun 18.

Department of Neurosurgery, Nagoya University Graduate School of Medicine, 65 Tsurumai-cho, Showa-ku, Nagoya, Aichi, 466-8550, Japan.

Background: Eccrine spiradenocarcinoma (SC), also known as malignant eccrine spiradenoma, is a rare malignant cutaneous adnexal neoplasm arising from long-standing benign eccrine spiradenoma. Malignant skin tumors rarely show direct intracranial invasion. However, once the intracranial structure is infiltrated, curative excision with sufficient margins can become extremely difficult, particularly when the venous sinuses are involved. Read More

Infra-Temporal and Pterygo-Palatine Fossae Tumors: A Frontier in Endoscopic Endonasal Surgery-Description of the Surgical Anatomy of the Approach and Report of Illustrative Cases.

Int J Environ Res Public Health 2022 May 25;19(11). Epub 2022 May 25.

Programma Neurochirurgia Ipofisi-Pituitary Unit, IRCCS Istituto delle Scienze Neurologiche di Bologna, 40139 Bologna, Italy.

Infratemporal and pterygopalatine fossae (ITF and PPF) represent two complex paramedian skull base areas, which can be defined as jewelry boxes, containing a large number of neurovascular and osteomuscular structures of primary importance. They are in close communication with many craniofacial areas, such as nasal/paranasal sinuses, orbit, middle cranial fossa, and oral cavities. Therefore, they can be involved by tumoral, infective or inflammatory lesions spreading from these spaces. Read More

[Anatomy for Endoscopic Endonasal Skull Base Surgery].

No Shinkei Geka 2022 May;50(3):535-543

Department of Otolaryngology-Head and Neck Surgery, Nagoya City University, Graduate School of Medical Sciences.

Endoscopic endonasal skull base surgery has become popular due to its minimally invasive nature to the patient and the development of various medical devices. The reason why it is considered less invasive is that it is possible to reach the anterior skull base lesion using the corridor of the nasal cavity and paranasal sinuses. The roles of the nasal sinuses include acting as breathing pathways, warming, humidifying, and filtering of inhaled air, olfaction, and being a resonant cavity, all of which are important for a comfortable life, and the loss of these functions reduces the quality of life.

Department of Otolaryngology Head and Neck Surgery, Xiangya Hospital, Central South University, Changsha, Hunan 410008, China; Otolaryngology Major Disease Research Key Laboratory of Hunan Province, Changsha, Hunan 410008, China; National Clinical Research Center for Geriatric Disorders, Xiangya Hospital, Central South University, Changsha, Hunan 410008, China; Anatomy Laboratory of Division of Nose and Cranial Base, Clinical Anatomy Center of Xiangya Hospital, Central South University, Changsha, Hunan 410008, China. Electronic address:

Adenoid cystic carcinoma (ACC) is a rare malignant tumor derived mainly from the salivary glands, representing approximately 1% of all headandneck carcinomasand 10% of all salivary gland neoplasms. ACC displays a paradoxical behavioral combination of an indolent growth pattern but an aggressive progression, with local recurrence and distant metastasis. The propensity of ACC of the head and neck (ACCHN) for perineural invasion and its anatomical location, especially if it extends to the nasal cavity and paranasal sinuses, facilitates tumor involvement in the surrounding structures, such as the orbit, pterygopalatine fossa, Meckel'scave, and cavernous sinus, which can lead to skull base involvement and intracranial extension.

Adenoid cystic carcinoma of sinonasal origin masquerading as an intraconal lesion.

BMJ Case Rep 2022 May 13;15(5). Epub 2022 May 13.

Radiodiagnosis, Datta Meghe Institute of Medical Sciences - Wardha Campus, Wardha, Maharashtra, India.

Adenoid cystic carcinoma is an uncommon tumour of the salivary glands, although affliction of mucin-producing glands present in the oral cavity, oropharynx and paranasal sinuses is not uncommon. Other possible sites are lacrimal, oesophagus, trachea-bronchial tree, lungs, uterus, cervix, prostate. These tumours have a tendency to be aggressive and most show invasion into the adjacent region.

Biological roles and clinical significance of estrogen and androgen receptors in head and neck cancers.

J Cancer 2022 4;13(7):2189-2199. Epub 2022 Apr 4.

General Hospital, Clinical Medical Academy, Shenzhen University, Shenzhen 518055, Guangdong, China.

Head and neck cancers (HNC) include malignant tumors that grow in and around the mouth, larynx, throat, sinuses, nose, and salivary glands. Accumulating evidence in malignancies suggests the aberrant expressions of the estrogen receptor (ER) and the androgen receptor (AR) in HNC, such as in laryngeal cancer and cancer of the salivary gland. Moreover, the signaling pathways involving these receptors that mediate tumorigenesis, proliferation, apoptosis, migration, and invasion have been elucidated. Read More
