ABSTRACT

BACKGROUND Oral squamous cell carcinoma (OSCC) is the most common of head and neck malignancies in well-developed countries. In most cases, patients with OSCC experience a degree of nutritional status disturbances and decreased quality of life (QoL). This study aimed to compare nutritional status and QoL in 51 patients before and after surgery for OSCC. MATERIAL AND METHODS Fifty-one eligible patients with OSCC were followed during a 3-year period (2019-2022). For all patients, we determined body mass index (BMI), serum albumin (ALB), prognostic nutritional index, and nutritional risk index before and after treatment. Also, all patients completed a standardized QoL questionnaire before and after treatment. The obtained data were compared between the groups by using the t test and multivariate Cox regression. RESULTS The values of BMI and NRI were statistically significantly different between the preoperative and postoperative measurements (24.1 kg/m² vs 21.1 kg/m², and 103 vs 100.1, respectively, P=0.001), while values of ALB and prognostic nutritional index did not differ significantly (41.35 g/L vs 39.1 g/L, and 48.5 vs 46.2, respectively). Dysphagia (P=0.03) and chewing problems (P=0.04) were found to be the 2 most important factors decreasing the QoL of patients. CONCLUSIONS Based on our results, BMI and NRI were the most sensitive parameters of nutritional status. Dysphagia and chewing problems were the 2 most important factors affecting the QoL in patients with OSCC.

ABSTRACT

BACKGROUND A fracture of the orbital floor can lead to complications such as enophthalmos, impaired eye motility, or diplopia, which is why it is necessary to reconstruct the bony walls of the orbit. This study from a single center in Nis, Serbia, included 58 patients with unilateral orbital floor fracture and aimed to use volumetric measurement to compare the fractured and non-fractured orbit before and after surgery using a titanium implant or a resorbable poly-d, l-lactic acid (PDLLA) implant. MATERIAL AND METHODS From 2018 to 2022, a total of 58 patients with unilateral orbital floor fractures were treated at the Clinic of Dental Medicine, Nis. Computed tomography examination was used for volumetric measurement of the fractured and non-fractured (contralateral) orbit before and after the surgical procedure. A titanium implant was used in 31 patients, and a PDLLA implant was used in 27 patients. RESULTS Orbital volume ratio did not differ statistically significantly in relation to the type of implant (P=0.591). The postoperative volume did not differ statistically significantly from the volume of the contralateral side (titanium, P=0.212; PDLLA, P=0.232). There was a significant correlation between orbital volume and enophthalmos both before and after surgery (P=0.012, P=0.018, respectively). CONCLUSIONS Measuring the preoperative volume of the injured orbit is sufficient data for an indication because reconstruction depends primarily on the correlation between the volume and enophthalmos. The findings from this study showed that preoperative orbital volumetry using computed tomography evaluated enophthalmos and provide data to assist orbital floor reconstruction.

ABSTRACT

BACKGROUND/AIM: Cancers of the lip, oral cavity and pharynx (LOCP) are frequently grouped together mainly because they have similar risk factors. The incidence rate of these cancers varies worldwide depending on the geographic location. The aim of this study was to determine trends in age-standardized incidence rates of LOCP cancers in the Belgrade population during a 12-year period, from 1999 to 2010. METHODS: From The Serbian Cancer Registry (The Registry), we extracted all cases of LOCP cancers registered in Belgrade from January 1, 1999 to December 31, 2010. Joinpoint regression analysis was used to define trends and annual percentage change (APC). RESULTS: A total number of 2,025 (1,509 in men and 516 in women) LOCP cancers were reported to the Registry during the study period. The age standardized rate (ASR) for the entire period and for all LOCP cancers, was 6.24 per 100,000 persons (10.35 for men and 2.86 for women). ASR for lip cancers decreased (p < 0.001) during the study period with APC of -8.4%. The ASR for oral cavity and pharyngeal cancers increased (p < 0.05). CONCLUSION: Our results show a significantly decreasing trend of the incidence rate for lip cancers in the population of the city of Belgrade between 1999 and 2010. On the contrary, the incidence of oral cavity and pharyngeal cancers increased for both men and women.

ABSTRACT

Introduction: Mucoepidermoid carcinoma, compared to other tumors of salivary glands, occurs in 5­10% of cases. Histopathologically, it is divided into a well differentiated tumor that is of low-grade of malignancy, and a medium and poorly differentiated tumor of high grade of malignancy. Central mucoepidermoid carcinoma (CMEC) of the mandible was firstly described by Lepp in 1936, on a 66-year-old female patient. CMEC is characterized by atypical clinical image and radiological manifestation. Case Outline: A 55-year-old female patient was examined at the Clinic of Dentistry in Nis, Serbia, with anamnestic data regarding the presence of painless swelling in the right side of the mandible. Considering the histopathological results and presence of enlarged lymph nodes, right hemimandibulectomy and tumour excision from pterygomandibular space followed by supraomohyoid neck dissection was done. In due course, postoperative radiotherapy was applied (60 Gy) Conclusion: CMEC represents a rare tumor, characterized by local tissue destruction and ability to metastasize. Initial biopsy represented the key in preoperative planing. Radical excision with neck lymph node dissection followed by postoperative radiotherapy in our case represent a successful method of treating CMEC of the mandible.

ABSTRACT

INTRODUCTION: Nonmelanoma skin cancers in the literature are mainly related to basal cell and squamous cell skin carcinoma. OBJECTIVE: The aim of the study was to determine the trend in the incidence of histological types of nonmelanoma skin cancers in the population of the city of Belgrade from 1999 to 2011. METHODS: From the Serbian National Cancer Registry we extracted all recorded cases of skin cancer in Belgrade from January 1st 1999 to December 31st 2011. Incidence rates were standardized by the method of direct standardization with the world population as the standard population. Trends and annual percentage change (APC) of incidence rate were calculated by performing joinpoint regression analyses. RESULTS: Incidence rate of nonmelanoma skin cancer showed significantly increasing trend between 1999 and 2006 with APC of 8.6% (95% Cl: 5.6-11.7), basal cell carcinoma increased with APC of 8.4% (95% Cl: 5.2-11.6) and squamous cell skin carcinoma with APC of 9.33% (95% Cl: 5.7-13.1). The incidence increased with age for both men and women, especially after the age of 60. CONCLUSION: Our results showed a continuously increasing incidence trend of both basal cell and squamous cell skin carcinomas in the population of the city of Belgrade between 1999 and 2011. Adequate primary and secondary prevention would certainly be successful in reducing this type of cancer in the future.

ABSTRACT

AIM: To describe demographic and histomorphological characteristics of 139 patients with epithelial salivary gland tumors in the Southeastern Serbia population. METHODS: A total number of 139 patients with epithelial tumors arising in major and minor salivary glands in the period 2010-2012 was evaluated. After standard tissue proceeding, the routine haematoxylin-eosin (HE) and histochemical alcian blue-periodic acid-Schiff (AB - PAS) methods were used for histomorphological examination. RESULTS: Among 139 patients, 102 (73.38%) had benign, and 37 (26.62%) malignant tumors. The majority of tumors were localized in the parotid gland, in 117 (84.17%) patients. Among benign tumors there were 50 (49.02%) pleomorphic adenoma, 48 (47.06%) Warthin's tumor, two (1.96%) myoepithelioma, and two (1.96%) oncocytoma. In the group of malignant tumors the most common was mucoepidermoid carcinoma, in 12 (32.43%) patients, carcinoma ex pleomorphic adenoma in six (16.22%), adenoid cystic carcinoma in five (13.51%), and oncocytic carcinoma in three (8.11%) patients. CONCLUSION: Benign tumors were more common than malignant ones, with predominance of pleomorphic adenoma. Malignant tumors are less common than benign in the large salivary glands, and more common in the minor salivary glands. Histochemical AB-PAS method helps in the diagnosis of mucinous salivary gland carcinoma.

ABSTRACT

PURPOSE: To investigate both the clinicopathological and immunohistochemical characteristics of a very rare skin cancer - Merkel cell carcinoma (MCC) - and to review the relevant literature. METHODS: The study group was composed of 12 patients, with mean age 53.08±10.26 years. Multiple subcutaneous masses and lymph node metastases were surgically removed. Paraffin blocks of formaldehyde-fixed tumor tissue were cut and stained for histological, histochemical and immunohistochemical studies. The following antibodies (Dacopatt) were used: Chromogranin A, CK20, CK7, Melan A, CD20 and CD45Ro. RESULTS: The tumors involved the dermis while sparing the epidermis. The most frequently affected sites were sun-exposed skin (8 patients on the head and neck) and the most common histological subtype of MCC was the intermediate variant. Six patients had lymph node metastasis and 2 had locoregional recurrences. Haematogenous lung metastases of MCC and primary located in the trunk were found only in our youngest patient (36-year-old). Immunostaining revealed positive reactivity for neuroendocrine and epithelial markers and negative reactivity for melanoma, B/T lymphomas and small cell metastatic lung carcinoma. CONCLUSION: MCC is a rare malignant primary cutaneous neoplasm with epithelial and neuroendocrine differentiation, demanding wide local excision. The pathological differential diagnosis includes basal cell carcinoma, melanoma, lymphoma, and metastatic small cell lung carcinoma. The diagnosis of MCC is possible only immunohistochemically, by using the wide spectrum of antibodies, characteristic of microscopically similar tumors.

ABSTRACT

Oro-antral communications (OAC) greater than 4-5 mm in diameter can seldom be counted on to heal spontaneously without the necessity for surgical closure. The initial experience in applying an absorbable polyglactin/polydioxanon implant (Ethisorb(®)), in non-surgical closure of OAC ranging from 5 to 7 mm in diameter, is presented. Twelve patients of varying ages with OAC up to 72 h in duration, have been treated with Ethisorb(®). Failures were not demonstrated in the form of the creation of an oro-antral fistula (OAF), and in all patients, OAC-s were closed with the epithelization of post-extraction wounds up to 21 days after implantation of Ethisorb(®). Based on these initial encouraging results, we propose that an Ethisorb(®) biopolymeric absorbable implant can be used in selected clinical cases for non-surgical closure of OAC.

ABSTRACT

A salivary fistula is one of possible postoperative complications in the surgery of parotid gland tumors. We present three cases of postparotidectomy salivary fistulas, successfully treated by surgical access using 2-octyl-cyanoacrylate while closing the skin layer. The previous treatment of these cases by other therapeutic options did not give satisfactory results. In a 5-year follow-up period there were no signs of fistulas relapses. The surgical access with use of 2-octyl cyanoacrylate can be one of therapeutic options for the closing of postparotidectomy salivary fistulas, especially in cases where other therapeutic accesses are not successful.

ABSTRACT

INTRODUCTION: In 1963 Beckwith presented a report on the first patient with extreme cytomegaly of adrenal cortex, hyperplasia of kidneys and pancreas and Leydig cell hyperplasia. Wiedemann completed description of the new syndrome by adding umbilical hernia and macroglossia. The diagnosis is made based on the clinical signs of omphalocele or some other umbilical deformity, macroglossia, congenital asymmetry, visceromegaly (liver, pancreas, and kidneys). CASE OUTLINE: A 16-month-old male child was admitted for examination because of macroglossia. He underwent examination on several occasions by an endocrinologist due to recurrent hypoglycaemic crisis. The patient was observed by a paediatric neurophysicatrist for disorders of mental development. Hypoglycaemia, muscular hypotonia of the anterior abdominal wall with umbilical hernia and macroglossia were observed by clinical examination. Inratraoral examination revealed macroglossia with microstomia, suckling and swallowing difficulties, hypotonia of the perioral muscles with increased salivation. It was therefore decided to perform surgical reduction of the prominent tongue and develop good condition for nutrition, speech function and the development of orofacial system. CONCLUSION: The diagnosis of macroglossia is based on subjective clinical criteria such as the morphology and amount of protrusion of the tongue, difficulty in articulating sounds, breathing, and hypersalivation. Some authors have suggested that the tongue size may be analyzed radiographically with a cephalogram. Treatment of macroglossia is controversial because of the absence of objective clinical criteria.

ABSTRACT

INTRODUCTION: Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. They are described as both superficial and deep formations with most frequently slow intermittent growth. Apart from aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also an optical nerve compression syndrome. CASE OUTLINE: In this paper, we described a child with a congenital orbital dermoid cyst localized in the upper-nasal quadrant that was showing signs of a gradual enlargement and progression. The computerized tomography revealed a cyst of 1.5-2.0 cm in size. At the Maxillofacial Surgery Hospital in Nis, the dermoid cyst was extirpated in toto after orbitotomy performed by superciliary approach. Postoperative course was uneventful, without inflammation signs, and after two weeks excellent functional and aesthetic effects were achieved. CONCLUSION: Before the decision to treat the dermoid and epidermoid cysts operatively, a detailed diagnostic procedure was necessary to be done in order to locate the cyst precisely and determine its size and possible propagation into the surrounding periorbital structures. Apart from cosmetic indications, operative procedures are recommended in the case of cysts with constant progressions, which cause the pressure to the eye lobe, lead to motility disturbances and indirectly compress the optical nerve and branches of the cranial nerves III, IV and VI.

ABSTRACT

INTRODUCTION: Reconstruction of perinasal area is still a challenge for the surgeon who is involved in excisional tumor surgery. The authors report their experience in reconstruction of hemi-nose defects with the free microvascular submental island flap prelaminated with oral mucosa. MATERIAL AND METHODS: A 73-year-old male patient with recurrent extensive basal cell carcinoma of the right hemi-nose (nasal ala and lateral nasal part) and portion of the upper lip underwent to excisional surgery and creation of lateral nasal defect 3 x 2 cm in size. Six months after the first surgery the reconstruction of postoperative defect was done by means of free microvascular submental flap prelaminated with oral mucosa. RESULTS: After necrosis of flap 3 mm x 4 mm in size around the tip zone of the nose on the 7" postoperative days, the rest of microvascular submental flap prelaminated with oral mucosa survived completely with good cosmetic and nasal respiratory results. CONCLUSION: This flap can be used successfully in reconstruction of the hemi-nose area. Color and texture of the flap match with adjacent tissue and adequate diameter of submental vessels and reasonably long vascular pedicle enables successful microvascular anastomosis.

ABSTRACT

BACKGROUND/AIM: Sjögren's syndrome is a chronic autoimmune systemic disease characterized by polyglandular tissue destruction, leading to keratoconjunctivitis sicca and xerostomia. These patients have 44-fold increased risk of developing salivary gland lymphoma, of which 80% are marginal zone (MALT) type. Having in mind that criteria for distinguishing benign lymphoepithelial lesions from MALT lymphoma are obscure, the aim of this study was to provide practical information that could be integrated into diagnostic practice. METHODS: Among 32 parotidectomies, 27 cases were identified as having benign lymphoepithelial disorders and 5 cases low grade MALT lymphoma. Histological sections were stained routinely with hematoxylin and eosin (H&E and special stains. Immunohistochemical study was performed by LSAB2 method, by using primary antibodies for CD20, CD3, Kappa and Lambda light chains and Cytokeratin (Dako Denmark). RESULTS: The 27 patients with Sjögren's sialoadenitis (22 women and 5 men), and 5 patients with MALT lymphoma (only women) were included in this analysis. According to the Ann Harbor Classification, all patients with MALT lymphoma had stage IE. Both groups of patients had an indolent clinical course, except permanent, rapid parotid enlargement in the patients with MALT lymphoma. Histologically, the periductal lymphoid infiltrate, gradually extended to the acini, completely replacing them by a sea of polyclonal lymphocytes, immunoblasts, germinal centers and plasma cells (confirmed immunohistochemically), but sparing the ducts and preserving lobular appearance. The histological feature of salivary gland MALT lymphoma included heterogeneous B-cell infiltrate that totally or subtotally had effaced the normal glandular structure. Malign lymphoepithelial lesions, representing infiltration of the ductal and epithelial structures by monoclonal neoplastic B-cells, positive for CD20, were highlighted by antibody to cytokeratin. CONCLUSION: The optimal diagnosis of salivary gland MALT lymphoma requires careful integration of clinical, morphological and immunohistochemical results.

ABSTRACT

BACKGROUND: Mucosa-associated lymphoid tissue (MALT) lymphoma was described for the first time in 1983 by Isaacson and Wright. It was classified into extranodal non-Hodkin's lymphomas of B-cell lymphocytes of the marginal zone of reactive lymphe follicles. It is characterized by both hyperplasia and colonization of plasmocytic, centrocytoid and monocytoid cells, by the infiltration of interfollicular and parafollicular parts of interstitium, as well as by the invasion of clusters of neoplastic lymphoid cells of the glandular epithelium, forming the pathognomic lymphoepithelial MALT limphoma lesions. CASE REPORT: In this paper we presented the two female patients, 59 and 75 years of age, with MALT lymphomas, associated with Miculicz's and Sjögren's syndromes. The paper also underlined rather many-month-long, indolent clinical course, evalution of both tumors, massive in size, as well as two-sided localization in the case of the Miculicz's syndrome. After the subtotal parotidectomy, using conservation of nerve facialis, the tissue blocks were fixed in 10% formaldehyde. The paraffine sections were stained by routine histochemical and an immunohistochemical method by using monoclonal antibodies for both B-cell and T-cell lymphomas, due to the verification of lymphoepithelial lesions. The MALT lymphoma diagnosis was based on the histological criteria and confirmed by an immunohistochemical method. After the surgical therapy accompanied by chemotherapy, the patients were controlled at regular intervals, and residual MALT lymphoma did not appear. CONCLUSION: MALT lymphoma is a rare tumor of the salivary glands, with the most frequent localization in the parotide gland. It had a slow clinical course, without metastases in both patients. The diagnosis was made pathohistologically and confirmed immunohistochemically. The surgical therapy was accompained by adjuvant chemotherapy.

ABSTRACT

This paper reports the results of experimental use of glass-ionomer microimplants in the augmentation of the maxillary alveolar ridge in dogs. The study included ten adult mongrel dogs 5 years of age, weighing between 50 and 70 pounds (25-30 kg), divided into 2 groups of 5 dogs each. In both groups, the maxillary 4th premolar and 1st molar were removed after the elevation of a buccal mucoperiosteal flap. The alveolar bone adjacent to the extracted teeth was also removed. In the experimental group (5 dogs), Ionogran a glass-ionomer microimplants (GIMIs) (Ionogran particle size of 0.5-1.0 mm, IONOS Medizinische Produkte GmbH & Co. KG, D-8031 Seefeld, Gemany) were used for augmentation and were inserted in the created defects. The extraction sockets and bone defects were augmented with an average amount of 2 g of GIMIs. In the control group, the bone defects were left unfilled as a control for bone healing. Histological examination showed that the glass-ionomer microimplants were extremely osteoconductive and inert materials. Stimulation of growth of new bone tissue in contact with the glass-ionomer microimplants was evident. No inflammatory cells were detected on or adjacent to the GIMIs. In the control group, incomplete bone healing with fibrous scar tissue and inflammatory cells was noted. These results indicate that glass-ionomer microimplants represent highly osteoconductive and biocompatible materials for use in bone surgery.
