Parvovirus B19 infection in a patient of juvenile arthritis: A case report

Parvovirus B19 infection, or fifth disease or erythema infectiosum, is a self-limiting viral exanthem and can occur along with other connective tissue disorders. Occasionally, children may have preceding chronic joint complaints suggestive of juvenile idiopathic arthritis. A 7-year-old female patient presented to the outpatient department with a rash over her face, upper and lower limbs, and trunk, which was preceded by fever. The patient is a known case of juvenile arthritis. On examination, there were multiple erythematous and skin-colored plaques over cheeks; few pustules over lips; multiple erythematous papules over upper limbs, lower limbs, and trunk; multiple erythematous macules over palms; and swelling over interphalangeal joints of bilateral hands, elbow and knee joints with genu valgum deformity of limbs. The patient was given topical antibiotic and steroid combination cream and oral antihistaminic for her cutaneous complaints.

Study on quantitative analysis of bracket-induced nonlinear response of labio-cheek soft tissue during the orthodontic process / 生物医学工程学杂志

In the orthodontics process, intervention and sliding of an orthodontic bracket during the orthodontic process can arise large response of the labio-cheek soft tissue. Soft tissue damage and ulcers frequently happen at the early stage of orthodontic treatment. In the field of orthodontic medicine, qualitative analysis is always carried out through statistics of clinical cases, while quantitative explanation of bio-mechanical mechanism is lacking. For this purpose, finite element analysis of a three-dimensional labio-cheek-bracket-tooth model is conducted to quantify the bracket-induced mechanical response of the labio-cheek soft tissue, which involves complex coupling of contact nonlinearity, material nonlinearity and geometric nonlinearity. Firstly, based on the biological composition characteristics of labio-cheek, a second-order Ogden model is optimally selected to describe the adipose-like material of the labio-cheek soft tissue. Secondly, according to the characteristics of oral activity, a two-stage simulation model of bracket intervention and orthogonal sliding is established, and the key contact parameters are optimally set. Finally, the two-level analysis method of overall model and submodel is used to achieve efficient solution of high-precision strains in submodels based on the displacement boundary obtained from the overall model calculation. Calculation results with four typical tooth morphologies during orthodontic treatment show that: ① the maximum strain of soft tissue is distributed along the sharp edges of the bracket, consistent with the clinically observed profile of soft tissue deformation; ② the maximum strain of soft tissue is reduced as the teeth align, consistent with the clinical manifestation of common damage and ulcers at the beginning of orthodontic treatment and reduced patient discomfort at the end of treatment. The method in this paper can provide reference for relevant quantitative analysis studies in the field of orthodontic medical treatment at home and abroad, and further benefit to the product development analysis of new orthodontic devices.

Effects of different frequencies of pricking-bloodletting at auricular points plus auricular point sticking therapy on the serum levels of related factors in patients with acne vulgaris / 针灸推拿医学（英文版）

Objective: To observe the effects of different frequencies of pricking-bloodletting at auricular points plus auricular point sticking therapy on the levels of the serum immunoglobulin G (IgG), immunoglobulin M (IgM), testosterone (T), and insulin-like growth factor-1 (IGF-1) in patients with acne vulgaris (AV). Methods: Ninety patients with AV were randomly assigned to treatment group 1, treatment group 2, and treatment group 3 according to the random number remainder grouping method, with 30 cases in each group. All three groups received pricking-bloodletting at auricular points plus auricular point sticking therapy. Treatment group 1 was treated once a week, treatment group 2 was treated twice a week, and treatment group 3 was treated 3 times a week. Four-week treatment was taken as 1 treatment course, and 3 treatment courses were observed. On the day before the start of the study and on the day next to the end of each course, the global acne grading system (GAGS) score was recorded, and 3 mL of blood from the median cubital vein was collected to test the serum levels of IgG, IgM, T, and IGF-1. After 3 courses of treatment, the efficacy index was calculated according to the GAGS score, and the serum indicators in patients with effective treatment (efficacy index ≥20％) and complete sampling were analyzed. Results: A total of 60 patients were included in the final blood indicator analysis. After 3 courses of treatment, the intra-group comparisons showed that the serum IgG level increased significantly in patients in treatment group 1 (P<0.01); the serum T level decreased significantly in the female patients in treatment group 2 (P<0.05); the IGF-1 level significantly decreased in the patients in all three groups (P<0.05 or P<0.01). There were no significant differences in the serum levels of IgG, IgM, T, and IGF-1 among the three groups at each time point (P>0.05). Conclusion: Pricking-bloodletting at auricular points plus auricular point sticking therapy can affect the levels of serum IgG, T, and IGF-1 in AV patients. The level of the serum IGF-1 can be reduced by treatment once a week, twice a week, or 3 times a week. Treatment once a week can increase the patients' serum IgG level, and treatment twice a week can significantly decrease the serum T level in female patients. Reducing the serum IGF-1 level may be one of the action mechanisms of pricking-bloodletting at auricular points plus auricular point sticking therapy in treating AV.

Pleomorphic Adenoma of the Cheek. Case Report with Review / Adenoma Pleomórfico de Mejilla. Reporte de Caso con Revisión

ABSTRACT: Pleomorphic adenoma (PA), also called benign mixed tumor, is the most common tumor of the salivary glands. About 70 % of these tumors occur in the parotid gland and an uncommon site are the minor salivary glands. The most common sites of PA of the minor salivary glands are the palate followed by lips and cheek. Other rare reported sites include the fauces, floor of the mouth, tongue, tonsil, pharynx, retromolar area and nasal cavity. Here we report a case of pleomorphic adenoma of minor salivary glands of the cheek in a 22-year-old male. The mass was removed by wide local excision with adequate margins, and the patient was followed for 1-year post operatively with no recurrence.

El tumor glómico es una neoplasia vascular originada de las células del músculo liso del componente neuromioarterial, responsable del control del flujo sanguíneo microvascular. Representa el 1,6% de todos los tumores de tejidos blandos, localizándose principalmente en la zona subungüeal y clínicamente muy doloroso. Su diagnóstico puede ser tardío debido a su pequeño tamaño, manifestaciones clínicas inespecíficas y localizaciones anatómicas inusuales. El tratamiento principalmente es quirúrgico, el cual es curativo, permitiendo además la confirmación histopatológica. Se presenta el reporte de caso de una paciente de 13 años de edad con un tumor glómico de localización inusual en mucosa bucal.

The glomus tumor is a vascular neoplasm originating from smooth muscle cells of neuromyoarterial component, responsible for the control of microvascular blood flow. It represents 1.6% of all soft tissue tumors, being located mainly in the subungual area and clinically very painful. Diagnosis may be delayed because of their small size, nonspecific clinical manifestations and unusual anatomical locations. Treatment is primarily surgical, which is healing, also allowing the histopathologic confirmation. The case report of a 13-year-old patient with an unusual-located glomus tumor in the oral mucosa is presented.

Efficacy of Fentanyl Buccal Tablets for Patients Who Cannot Retain at the Above a Rear Molar between the Upper Cheek and Gum

Fentanyl buccal tablets place the tablet at the buccal site (above a rear molar, between the upper cheek and gum) and wait until it dissolves, but some patients may not be able to retain it due to defects of the maxillary molars. The aim of this study was to evaluate the effectiveness and safety of fentanyl buccal tablets when they were used outside the buccal site. Seven patients were treated with fentanyl buccal tablets outside the buccal site. For each of 5 episodes in which effective dose was identified, were investigated to average pain intensity assessed on a 0 to 10 numerical rating scale at 30 min postadministration and reduction in pain intensity of more than 33%. Pain intensity significantly decreased at 30 min postadministration in 5 patients with effective doses identified (p<0.001). In 92.0% of episodes treated, there was a reduction in pain intensity of more than 33%. Adverse events were somnolence and nausea with mild. However, these effects did not result in discontinuation of medication. Our findings suggested that fentanyl buccal tablets can be used effectively and safely even when patients used outside the buccal site.

A bichectomia na harmonização e função orofacial / The bichectomy in harmonization and orofacial function

A Cirurgia Plástica e a Odontologia constituem áreas intimamente envolvidas com a face, por ser esta "o cartão de visitas" do ser humano. O apelo estético está relacionado com a mídia, e também com a aceitação física e emocional. Uma estética harmoniosa representa um aumento da autoestima e uma demonstração de sucesso socioeconômico. A multidisciplinaridade tem ganho espaço nas ciências da saúde por representar uma associação de conceitos e técnicas entre diversos profissionais altamente especializados para a máxima performance dos resultados, trazendo realização e conforto para o paciente. Assim, a bichectomia é um procedimento contemporâneo que visa uma ressecção parcial do corpo adiposo da bochecha, com o intuito estético e funcional. Estético porque proporciona uma face mais harmônica; e funcional porque visa a correção de incômodos traumáticos promovidos por uma interferência na mastigação. O objetivo desta revisão sistemática foi ilustrar clínicos e pesquisadores sobre o procedimento cirúrgico (bichectomia) calcado em bases científicas evidenciáveis e em conhecimentos ético-legais.

Plastic surgery and Dentistry are areas closely involved with the face, as this is the "visiting card" of the human being. The aesthetic appeal is related to the media, but also to physical and emotional acceptance. A harmonious aesthetic represents a better self-esteem and a demonstration of socio-economic success. Multidisciplinarity has gained space in health sciences because it represents an association of concepts and techniques among several highly specialized professionals for maximum results performance, bringing achievement and comfort to the patient. Thus, bichectomy is a contemporary procedure that aims at a partial resection of the cheek adipose body for aesthetic and functional purposes. Aesthetic because it provides a more harmonious face; and functional because it aims to correct traumatic discomfort caused by interference with chewing. The aim of this systematic review was to illustrate clinicians and researchers about the surgical procedure (bichectomy) based on evidenced scientific and ethical-legal knowledge.

An unusual giant schwannoma over face diagnosed on FNAC: a case report

Schwannoma is a slow growing benign peripheral nerve sheath tumor arising from schwann cells. It is also known as neurilemmoma. Although it is common in the head and neck region, it rarely exceeds 10 cm in size. Usually Schwannomas are notlarger than 5 to 6 cm in diameter.Large tumors are uncommon and are found in posterior mediastinum or retroperitoneum. We are presenting an unusual giant cell schwannoma over face (cheek) measuring 12×10cmsin size which caused facial deformity to the patient. The tumor was diagnosed on FNAC where cell block was prepared and IHC was done which showed S-100 positivity. This size schwannomaover cheek site has not been reported in the literature as far our knowledge. Therefore this case is unique for its size over face.

The aim of this review is to provide current evidence on various techniques used to obtain a youthful lid-cheek junction and to show the role of blending the lid-cheek junction in modern lower blepharoplasty.

Treatment of acne vulgaris with auricular acupoint pricking-bloodletting plus auricular point sticking therapy: a randomized controlled study / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of auricular point pricking-bloodletting plus auricular point sticking therapy for acne vulgaris. Methods: A total of 66 patients with acne vulgaris were randomized into an observation group and a control group by the random number table, with 33 cases in each group. The observation group was treated with auricular point pricking-bloodletting plus auricular point sticking therapy, and the control group was treated only with auricular point sticking therapy. The treatments of both groups were performed twice a week, 4 weeks as a course of treatment, for 3 courses in total. The scores of skin lesions and dermatology life quality index (DLQI) scores were recorded before and after treatment to assess the clinical efficacy. Results: During the trial, there were 3 cases of drop-out both in the observation group and the control group. After 3 courses of treatment, the total effective rate of the observation group was 96.7％, while that of the control group was 76.7％. The difference between the two groups was statistically significant (P<0.05). The intra-group comparison showed that the scores of skin lesion and DLQI were both decreased with the increase of treatment times, that was, the scores were lower than those at the previous time point (allP<0.05). After 1, 2, and 3 courses of treatment, the scores of skin lesion and DLQI of both groups were statistically different from those of the same group before treatment (allP<0.05). At every time point during the treatment, the scores of skin lesion and DLQI of the observation group were lower than those of the control group, and the differences between the two groups were statistically significant (all P<0.05). Conclusion: Auricular point pricking-bloodletting plus auricular point sticking has a better curative effect than auricular point sticking therapy alone in the treatment of acne vulgaris, and has a time-effect correlation.

Two separate nodules of Merkel cell carcinoma occurring concomitantly on one cheek

Merkel cell carcinoma (MCC) is a rare and highly aggressive neuroectodermal carcinoma arising from mechanoreceptor Merkel cells. Multiple MCCs are even rarer. We report a case of two independent MCCs simultaneously present in the cheek of a patient, which were effectively and esthetically treated using a cheek flap. Punch biopsy performed in a 60-year-old woman admitted with a chief complaint of two skin-colored hard nodules in her left cheek, accompanied by an itching sensation, was suggestive of MCC. Accordingly, we performed sentinel lymph node biopsy through the modified Blair incision under general anesthesia, in cooperation with the head and neck surgery department. The defect was covered with a cheek flap by slightly extending the existing incision following wide excision with a safety margin of 1 cm. This paper is significant in that it introduces an effective reconstruction technique that maintains function using a cheek flap for the management of this rare case. In addition, this paper is the first to classify multiple MCCs according to the time of onset. We believe that this paper presents an effective alternative reconstruction technique with sentinel node biopsy through the modified Blair incision.

A Case of Secondary Trigeminal Neuralgia Caused by Infected Postoperative Maxillary Cyst

Postoperative maxillary cyst (POMC) is relatively common complication among patients who underwent Caldwell-Luc surgery. Patients with POMC usually have no symptoms, although cyst extension can result in bone destruction or cystic infection with pain. The trigeminal nerve consists of the ophthalmic nerve, maxillary nerve, and mandibular nerve. Among these branches, the maxillary nerve runs to the lateral and frontal sides of the maxillary sinus wall. POMC can rarely lead to trigeminal neuropathy caused by cyst enlargement that compresses some branches of the trigeminal nerve. Recently, we experienced a case with trigeminal neuralgia due to POMC. The patient was successfully treated with inferior meatal antrostomy. We report this rare case with a literature review.
