Highlights Leiomyosarcoma of the larynx a very rare malignancy. Leiomyosarcoma of the larynx may represent a serious diagnostic challenge. No therapeutic protocol has been established yet. Treatment modalities depends on size, location, extension of the tumor. The prognosis is conditioned by the quality of surgical excision and the occurrence of recurrence and metastases.

Thirty one  samples of gum swabs were collected from patients with tooth caries (5-30 years old)  from the College of Science (Biology department )- University of Baghdad- Iraq for the period from October 2018 to December 2018. , The samples were transported, after inoculation in a transport media (nutrient broth), to the laboratory of the College of Science and then cultured on mannitol salt agar and  blood agar). The isolates belonging to Staphylococcus spp. were identified by biochemical tests and Vitek 2 compact system, while the more antibiotic resistant isolates were identified by using Polymerase Chain Reaction(﴾PCR)  and sequencing of 16SrRNA . The results showed sharp UV absorption peaks at 330 - 340nm and AFM at 56 nm. Transmission Electron Microscope (TEM) results showed that lemon silver nanoparticles (NPs) are spherical in shape. The results also demonstrated that  the silver NPs have a higher antibacterial activity with a diameter of inhibition zone that reached 16mm as compared with the common three mouthwash and toothpaste brands (Colgate, Crest and Close up) that had inhibition zone values of 5-8mm.

IntroductionNasopharyngeal adenoid cystic carcinoma is a rare tumor. Compared with others nasopharyngeal tumors, it is characterised by slow evolution but it is locally aggressive and has a high tendency to recurrences. Due to the rarity of cases, no consensus exists about treatment approaches.Presentation of the caseWe report the case of a 55-year-old-woman, with a locally advanced adenoid cystic carcinoma. The patient was operated by endoscopic surgery, received radiation and had a good objective response. The follow-up showed no local recurrence after one year.ConclusionThe aim of this work is to review the literature concerning this rare malignancy, and discusses treatment approaches in initial situations and during recurrences.We supported the interest of the intraoperative neuronavigation system for surgical safety.

Highlights Sialolipoma is a rare salivary gland tumor defined histologically by mature adipocytes encasing normal salivary glandular components. Complete excision of the mass with the lobes of the salivary glands involved seems to be adequate for definitive management. Congenital sialolipoma should be kept in mind in the differential diagnosis of congenital parotid mass, especially when CT scanning shows a well‑circumscribed fat‑like tissue within the parotid gland. Although surgical excision is usually sufficient to treat sialolipoma of the parotid gland, postoperative follow-up is necessary as multifocal lesions can potentially persist, which could lead to recurrence.

Highlights Penetrating craniofacial wounds caused by foreign bodies are a rare case of emergency facial surgery and require complex medical management. Their management must be rapid and multidisciplinary. The extraction of the foreign body should be under direct visual control in order to avoid or reduce the damage done to cerebral tissue.
