Cutaneous Sinus

Odontogenic cutaneous sinus tract (OCST) (synonyms: odontogenic cutaneous fistula, odontogenic subcutaneous granuloma, etc.) is an abnormal tube-shape formation which serves as a pathway for pus drainage from the locus of tooth–associated infection to the cutaneous lesion. OCST is a collective term and commonly is manifested in six cutaneous forms: as dimpling with fistula, cutaneous infiltration, nodule, suppurated nodule, abscess, or even cyst-like cutaneous formation. The purpose of this paper is to present the diverse clinical and radiological appearance (cone-beam computed tomography [CBCT] and ultrasound [US]) of single and multiple OCSTs based on the literature and our four cases. As long as limited publications present the ultrasound appearance of the OCSTs, we will focus on meticulous description of sonograms as well, giving a possibility for oral and maxillofacial surgeons to understand all advantages of that type of non-ionizing radiation diagnostics, avoiding misdiagnosis and mistreatment of OCSTs. Case 1: A 24-year-old male with OCST to the left mandibular region from the lower left first molar. Cutaneous lesion of OCST manifested as a transition stage from cutaneous infiltration to abscess. Case 2: A 41-year-old male with odontogenic cutaneous fistula of the right mandibular body region from the lower right second molar. It`s manifested as deep dimpling with active fistula. Case 3: A 45-year-old male with unilateral multiple OCSTs: 1) odontogenic cutaneous fistula of the left cheek from the left second maxillary molar and 2) a scar from a surgically treated OCST located in the projection of the left mandible from the tooth #3.6. Case 4: An 18-year-old male with OCST to left nasolabial fold and cheek from the upper left first molar. The pathology manifested as a subcutaneous abscess first and a nodule after the abscess lancing. These cases highlight the diverse cutaneous manifestations of the OCSTs. The US appearances of different parts of the OCST are presented, the popular terminology for the same cutaneous lesions are discussed, the new terms are proposed, and the treatment strategies based on histologic results are debated.

Cutaneous Sinus

Cutaneous sinus tracts of dental origin are relatively rare, but frequently misdiagnosed. In this case report, we present a seven-year-old patient with a cutaneous lesion in the left submandibular region misdiagnosed by a physician as an abscess secondary to suppurative lymphadenitis, and thus incorrectly treated with surgery and systemic antibiotics. Following a detailed dental examination, the patient was correctly diagnosed with an odontogenic sinus tract from a periapical abscess of tooth 36. Treatment of the immature tooth was initiated with apexification combined with nonsurgical endodontic treatment. The cutaneous and the periapical lesions were all resolved after the treatment and there has been no recurrence during an eight-year follow-up.

Dermatomyositis (DM) is an autoimmune inflammatory myopathy with some cutaneous manifestations. We present the case of a patient with a bone-depth skin ulceration on the elbow that was well healed with a transposition flap using a dorsal interosseous artery perforator. A 56-year-old man reported difficulties when climbing stairs and diffuse pain of unclear origin throughout his body that started 2 months previously. The patient was diagnosed with DM, and the department of plastic and reconstructive surgery was consulted for the management of an ulcerative skin lesion on the left elbow. The dorsal interosseous artery was first detected by vascular Doppler ultrasonography, and a transposition flap was designed including the pedicle. The flap was transposed to cover the bone exposure over the olecranon. At 4 weeks postoperatively, complete healing of the wound was observed without complications, and the patient had full range of motion of the elbow without pain. Despite major developments in the medical treatment of DM, ulcerative cutaneous lesions remain difficult to treat. Our experience suggests that the use of a transposition flap including the dorsal interosseous artery is suitable for the treatment of ulcerative lesions around the elbow in DM patients.

China officially recognized atypical pneumonia outbreak in December 2019; on 11 March 2020, the World Health Organization declared COVID-19 as a pandemic that is produced by a new coronavirus, named SARS-CoV-2, of rapid transmissibility, which can be asymptomatic, with mild to severe respiratory symptoms, and with cardiovascular, neurological, gastrointestinal, and cutaneous complications. Considering that the pandemic prolonged more than initially expected was prognostic, it is essential for the medical community to identify the signs and symptoms of COVID-19. Thus, this work’s objectives were to present cases of cutaneous lesions observed in COVID-19 Mexican patients. We register cutaneous lesions in COVID-19 patients referred from internal medicine and otorhinolaryngology services to dermatology. We presented four interesting cases with cutaneous lesions, including exanthema morbilliform, urticaria, chilblains, ecchymosis, and facial edema, and review the available literature. The most frequent cutaneous markers are rash, chilblains, and urticaria. Skin lesions may be the first manifestation of COVID-19, accompany initial respiratory symptoms, or appear during the disease course. Symptoms associated with vascular changes (livedo reticularis and vasculitis) are considered of poor prognosis.

SUMMARY Acanthamoeba spp. are free-living amebae that inhabit a variety of air, soil, and water environments. However, these amebae can also act as opportunistic as well as nonopportunistic pathogens. They are the causative agents of granulomatous amebic encephalitis and amebic keratitis and have been associated with cutaneous lesions and sinusitis. Immuno compromised individuals, including AIDS patients, are particularly susceptible to infections with Acanthamoeba. The immune defense mechanisms that operate against Acanthamoeba have not been well characterized, but it has been proposed that both innate and acquired immunity play a role. The ameba's life cycle includes an active feeding trophozoite stage and a dormant cyst stage. Trophozoites feed on bacteria, yeast, and algae. However, both trophozoites and cysts can retain viable bacteria and may serve as reservoirs for bacteria with human pathogenic potential. Diagnosis of infection includes direct microscopy of wet mounts of cerebrospinal fluid or stained smears of cerebrospinal fluid sediment, light or electron microscopy of tissues, in vitro cultivation of Acanthamoeba, and histological assessment of frozen or paraffin-embedded sections of brain or cutaneous lesion biopsy material. Immunocytochemistry, chemifluorescent dye staining, PCR, and analysis of DNA sequence variation also have been employed for laboratory diagnosis. Treatment of Acanthamoeba infections has met with mixed results. However, chlorhexidine gluconate, alone or in combination with propamidene isethionate, is effective in some patients. Furthermore, effective treatment is complicated since patients may present with underlying disease and Acanthamoeba infection may not be recognized. Since an increase in the number of cases of Acanthamoeba infections has occurred worldwide, these protozoa have become increasingly important as agents of human disease.

Abstract: Chronic cutaneous lesions affect 15% of diabetic human patients and represent a risk 15 to 46 times larger of limb amputations compared to people with normal glycemia. It is assumed that half of these amputations could be prevented by early treatment of wounds, for example, with proper cell therapy. Objectives: In this study, the action of the autologous transplant of mesenchymal stem-cells (MSC) was evaluated compared to the treatment with autologous platelet rich plasma (PRP) in the cicatrization of cutaneous lesions induced in diabetic mice. These animals were previously treated with streptozootocin to induce diabetes mellitus and round wounds of 1.5cm in diameter were created in the posterior region. Diameters of the wounds and healing time were evaluated during 30 days and the results were submitted to variance analysis and Tukey's test average. It was noticed that the animals treated with MSC presented a more accelerated cicatrization of the cutaneous lesion than the animals treated with PRP. However, the treatment with PRP presented better results than just the daily asepsis of the lesions with saline or covering them with semi-permeable bandage. Besides, the use of semi-permeable bandage kept the cutaneous lesions of diabetic mice did not interfere negatively with cicatrization, proved to be harmless to use, but kept the cutaneous lesions more hydrated than the ones exposed to the environment.
