RESUMO

Background: Mandibular condyle fractures in pediatric patients can lead to crippling sequelae such as ankylosis, pain and facial deformity if not managed properly. However, there is no consensus on the best approach for treating these fractures in children. Objective: This study aimed to describe the management of mandibular condyle fractures in growing patients across 14 maxillofacial departments worldwide. Methods: A retrospective multicenter study was conducted on children and adolescents aged 0 to 16 who had at least one mandibular condyle fracture. This study included patients who underwent expectant, closed, or open management and were treated over an 11-year period. Results: 180 patients had at least one mandibular condyle fracture, and 37 had a second condylar fracture. One hundred sixteen patients (65%) were males, and 64 (35%) were females (ratio 1.8:1). An expectant strategy was chosen in 51 (28%) patients, a closed treatment-stand-alone maxillomandibular fixation (MMF)-in 47 (26%), and open reduction and internal fixation (ORIF) was performed in 82 (46%) patients. The management varied significantly between the different departments (p < 0.0001). Significant differences were also identified between the fracture type (non-displaced, displaced or comminuted) and the management of the 180 patients with a single condylar fracture. Out of 50 non-displaced fractures, only 3 (6%) had ORIF, 25 (50%) had expectant management, and 22 (44%) had MMF. Out of 129 displaced fractures, 79 (62%) had ORIF, 25 (19%) had a soft diet, and 25 (19%) had MMF. Conclusions: Expectative management, MMF, and ORIF were all effective in treating pediatric mandibular condyle fractures, with a low incidence of complications and asymmetry.

RESUMO

INTRODUCTION: Trapdoor fractures of the orbital floor occur almost exclusively in the paediatric population. Despite being widely discussed in the literature, their management remains controversial. The objective of this retrospective study was to analyse the surgical experiences on paediatric trapdoor fractures in the maxillofacial centres participating in the WORMAT project. MATERIALS AND METHODS: 14 centres collected data for patients aged ≤16 years operated between January 2011 and December 2022. The demographic, cause and type of fracture, timing from injury to surgery, surgical approach, type of floor repair and outcomes were recorded. Diplopia, surgical wound infection, hardware loosening and dysesthesia in the infraorbital nerve area were recorded at follow-up. RESULTS: 43 patients were included: 25 children (0-12 y) and 18 adolescents (13-16 y) (mean age, 11.1 years). Surgical treatment was performed within 24 h in 51 % of the patients, within 24-72 h in 33 %, and beyond 72 h in the remaining. The orbital floor was repaired with a resorbable implant/membrane in 63 % of the patients, open reduction without an implant in 30 %, a titanium mesh implant in 3 adolescent patients. At follow-up (mean 16.3 months), 14 patients had residual diplopia in the upper fields, only two of these resolved within 6 months. DISCUSSION: A tendency toward an increased incidence of postoperative diplopia with longer intervals between trauma and surgery was observed. This study showed different choices regarding the material placed on the floor, with a preference for open reduction without implants in children, compared to the use of resorbable implants or membranes in adolescents.

RESUMO

Recently, microRNAs (miR) were identified to have potential links with oral squamous cell carcinoma (OSCC) and oropharyngeal squamous cell carcinoma (OPSCC) oncogenesis, specifically miR-21. Since HPV is a major risk factor for the development of these diseases, we aimed to search the literature regarding miR-21 expression in both HPV-positive and HPV-negative OSCC/OPSCC. The search was performed in the PubMed (MEDLINE), Scopus, Web of Science, and Cochrane electronic databases. The research question was as follows: Is there a difference in the tissue expression of miR-21 between patients with HPV-positive and those with HPV-negative OSCC/OPSCC? After conducting a meticulous search strategy, four studies were included, and they had a pooled sample size of 621 subjects with OSCC and/or OPSCC. Three studies did not find any significant difference in miR-21 expression between HPV-positive and HPV-negative OSCC/OPSCC. The findings of this systematic review showed that there are no differences in miR-21 expression between HPV-positive and HPV-negative OSCC/OPSCC. Nevertheless, it is worth noting that there are still insufficient studies regarding this important subject, because understanding how HPV influences miR-21 expression and its downstream effects can provide insights into the molecular mechanisms underlying OSCC/OPSCC development and progression.

RESUMO

INTRODUCTION: The aim of this 11-year retrospective multicentric study is to evaluate the policy of 14 maxillofacial surgery divisions in terms of titanium plate removal from paediatric patients who had undergone open reduction and internal fixation (ORIF) to treat maxillofacial fractures. MATERIAL AND METHODS: Patients ≤ 16 years undergoing surgical treatment for fractures of middle and lower third of the face between January 2011 and December 2022, with a minimum follow-up of 6 months, were included. Age (group A: ≤ 6 years, B: 7-12 years, C: 13-16 years), sex, fracture location and type, surgical approach, number, and location of positioned and removed plates, timing and indications for removal were recorded. RESULTS: 191/383 (50 %) patients (median age, 10 years; M:F ratio 2.1:1) underwent removal of 319/708 (45 %) plates. Maxillary dentoalveolar process (91 %), angle/ramus (63 %) and mandibular body (61 %) had a significantly higher removal rate than other fracture sites (p < 0.001). A significant decreasing trend in removal with increasing age was observed, from 83 % in Group A to 24 % in Group C (p < 0.001). On the total of positioned plates, 11 % were removed for symptomatic reasons (5 % infections, 6 % discomfort/pain) and 34 % for other reasons (28 % scheduled removal). DISCUSSION: This multicentric study showed that plate removal was not performed routinely in the paediatric population. The incidence and causes of symptomatic plates removal were consistent with the literature, while the plate removal rate from asymptomatic patients was lower. A correlation was found between increasing age and a reduction in the frequency of plate removal procedures.

RESUMO

BACKGROUND/AIM: Paediatric maxillozygomatic complex (MZC) fractures are uncommon, and there is a scarcity of data regarding their surgical treatment. The aim of this study was to analyse choices and outcomes of open reduction and internal fixation (ORIF) for MZC fractures among 14 maxillofacial centers around the world. MATERIALS AND METHODS: This multicentric retrospective observational study included patients ≤16 years of age with quadripod MZC fractures treated with ORIF from January 2011 and December 2022. The following data were collected: age, gender, dentition stage (deciduous, mixed, and permanent), cause of injury, type of fracture, surgical approach, site of osteosynthesis (infraorbital rim, zygomaticomaxillary buttress, frontozygomatic, and zygomaticotemporal sutures), material (titanium or resorbable) and number of plates used, and outcome. The minimum follow-up was 6 months. Statistical analyses were performed with Fisher's exact test or chi-squared test, as appropriate. RESULTS: Sixty-four patients (mean age, 12.3 years) with quadripod MZC fractures were included. Seventy-two percent of patients received a single-point fixation. The zygomaticomaxillary buttress was the most common site for fixation, both in single-point and two-point fixation schemes, especially in combination with the frontozygomatic suture. Increasing age was associated with a higher rate of plate removal (p < .001). Postoperative complications included 5 (7.8%) cases of wound infections, 2 (3.1%) infraorbital paraesthesia, 1 (1.6%) ectropion. Residual facial asymmetry was found in 5 (7.8%) patients and was not associated with the type of fixation (p > .05). CONCLUSIONS: This study highlights the possibility of using ORIF, even with a single point of fixation, for the treatment of displaced quadripod MZC fractures in the paediatric population. The zygomaticomaxillary buttress was the preferred site of fixation and allowed for adequate stabilization with no external scars and a low risk of tooth damage. Future prospective studies with long-term follow-up are needed to establish definitive surgical protocols and clarify the surgical decision-making.

RESUMO

PURPOSE: The training and preferences of surgeons influence the type of surgical treatment for mandibular fractures. This multicentre prospective study analyzed the current treatment strategies and outcomes for mandibular fractures with open reduction and internal fixation (ORIF). MATERIAL AND METHODS: This prospective study included patients aged ≥16 years who underwent ORIF for mandibular fractures in 12 European maxillofacial centers. Age, sex, pretrauma dental status, fracture cause, site and type, associated facial fractures, surgical approach, plate number and thickness (≤1.4 or ≥1.5 mm), duration of postoperative maxillomandibular fixation, occlusal and infective complications at 6 weeks and 3 months, and revision surgeries were recorded. RESULTS: Between May 1, 2021 and April 30, 2022, 425 patients (194 single, 182 double, and 49 triple mandibular fractures) underwent ORIF for 1 or more fractures. Rigid osteosynthesis was performed for 74% of fractures and was significantly associated with displaced ( P =0.01) and comminuted ( P =0.03) fractures and with the number of nonsurgically treated fracture sites ( P =0.002). The angle was the only site associated with nonrigid osteosynthesis ( P <0.001). Malocclusions (5.6%) and infective complications (5.4%) were not associated with osteosynthesis type. CONCLUSION: Rigid osteosynthesis was the most frequently performed treatment at all fracture sites, except the mandibular angle, and was significantly associated with displaced and comminuted fractures and the number of nonsurgically treated fracture sites. No significant differences were observed regarding postoperative malocclusion or infections among osteosynthesis types.

RESUMO

PURPOSE: Intraoperative stabilisation of bony fragments with maxillo-mandibular fixation (MMF) is an essential step in the surgical treatment of mandibular fractures that are treated with open reduction and internal fixation (ORIF). The MMF can be performed with or without wire-based methods, rigid or manual MMF, respectively. The aim of this study was to compare the use of manual versus rigid MMF, in terms of occlusal outcomes and infective complications. MATERIALS AND METHODS: This multi-centric prospective study involved 12 European maxillofacial centres and included adult patients (age ≥16 years) with mandibular fractures treated with ORIF. The following data were collected: age, gender, pre-trauma dental status (dentate or partially dentate), cause of injury, fracture site, associated facial fractures, surgical approach, modality of intraoperative MMF (manual or rigid), outcome (minor/major malocclusions and infective complications) and revision surgeries. The main outcome was malocclusion at 6 weeks after surgery. RESULTS: Between May 1, 2021 and April 30, 2022, 319 patients-257 males and 62 females (median age, 28 years)-with mandibular fractures (185 single, 116 double and 18 triple fractures) were hospitalised and treated with ORIF. Intraoperative MMF was performed manually on 112 (35%) patients and with rigid MMF on 207 (65%) patients. The study variables did not differ significantly between the two groups, except for age. Minor occlusion disturbances were observed in 4 (3.6%) patients in the manual MMF group and in 10 (4.8%) patients in the rigid MMF group (p > .05). In the rigid MMF group, only one case of major malocclusion required a revision surgery. Infective complications involved 3.6% and 5.8% of patients in the manual and rigid MMF group, respectively (p > .05). CONCLUSION: Intraoperative MMF was performed manually in nearly one third of the patients, with wide variability among the centres and no difference observed in terms of number, site and displacement of fractures. No significant difference was found in terms of postoperative malocclusion among patients treated with manual or rigid MMF. This suggests that both techniques were equally effective in providing intraoperative MMF.

RESUMO

Head and neck cancers (HNC) are a heterogeneous group of tumours mainly associated with tobacco and alcohol use and human papillomavirus (HPV). Over 90% of all HNC are squamous cell carcinomas (HNSCC). Sample material from patients diagnosed with primary HNSCC (n = 76) treated with surgery as primary treatment at a single centre were assessed for HPV genotype, miR-9-5p, miR-21-3p, miR-29a-3p and miR-100-5p expression levels. Clinical and pathological data were collected from medical records. Patients were enrolled between 2015 and 2019 and followed-up until November 2022. Overall survival, disease-specific survival and disease-free survival were assessed and correlated with clinical, pathological, and molecular data. Kaplan-Meier and Cox proportional hazard regression was used to assess different risk factors. In the study, male gender, HPV-negative HNSCC (76.3%) mostly located in the oral region (78.9%) predominated. Most patients had stage IV cancer (47.4%), and the overall survival rate was 50%. HPV was found not to affect survival, indicating that in this population, classic risk factors predominate. The presence of both perineural and angioinvasion was strongly associated with survival in all analyses. Of all miRNAs assessed, only upregulation of miR-21 was consistently shown to be an independent predictor of poor prognosis and may thus serve as a prognostic biomarker in HNSCC.

RESUMO

INTRODUCTION: The goal of mandibular fracture treatment is to restore static and dynamic occlusal functions. Open reduction and internal fixation (ORIF) of these fractures can be associated with an intraoperative and/or postoperative maxillo-mandibular fixation (MMF). The aim of this study was to analyse the use of perioperative MMF and its effects on occlusal outcomes in the management of mandibular fractures. MATERIAL AND METHODS: This multicentric prospective study included adult patients with mandibular fractures treated with ORIF. The following data were collected: age, gender, pre-trauma dental status (dentate, partially dentate), cause of injury, fracture site, associated facial fractures, surgical approach, type of ORIF (rigid, non-rigid or mixed), thickness and number of plates, modality of intraoperative MMF (arch bars, self-tapping and self-drilling screws [STSDSs], manual, other) and duration of postoperative MMF. The primary outcome was malocclusion at 6 weeks and 3 months. Statistical analyses were performed with Fisher's exact test or chi-square test, as appropriate. RESULTS: Between 1 May 2021 and 30 April 2022, 336 patients, 264 males and 72 females (median age, 28 years) with mandibular fractures (194 single, 124 double and 18 triple fractures) were hospitalized. Intraoperative MMF was performed in all patients. Osteosynthesis was rigid in 75% of single fractures, and rigid or mixed in 85% and 100% of double and triple fractures, respectively. Excluding patients who underwent manual reduction, postoperative MMF (median duration, 3 weeks) was performed in 140 (64%) patients, without differences by type or number of fractures (p > 0.05). No significant difference was found in the incidence of malocclusion in patients with postoperative MMF (5%, 95% confidence interval [CI], 2-10%) compared to those without (4%; 95% IC, 1-11%) (p > 0.05). CONCLUSION: Postoperative MMF was performed in more than half of the patients despite adequate fracture osteosynthesis, with wide variability amongst centers. No evidence of a reduction in the incidence of postoperative malocclusion in patients treated with postoperative MMF was found.

RESUMO

AIM: To analyze the differences in the population of perivascular and peritubular Leydig cells (LC) and the number of Reinke's crystals (RCs) in the testicles of infertile men with non-obstructive and obstructive azoospermia. METHODS: This retrospective case-control study was conducted on the testicle tissue of infertile men with obstructive (n=10) and those with non-obstructive azoospermia (n=100). Stereological analysis was performed on 7-µm paraffin sections. Measurements were carried out by using the Weibel multipurpose test system. RESULTS: Patients with non-obstructive azoospermia had a higher total/absolute number of LCs in the perivascular space (P=0.034). In these patients, no significant difference was found in the total and absolute number of RCs between the peritubular and perivascular space. Patients with obstructive azoospermia had around three times higher absolute number of RCs in both the peritubular and perivascular spaces (P=0.002; P<0.001) than non-obstructive group. CONCLUSION: Our results suggest that in patients with non-obstructive azoospermia LCs migrated or had different densities in the peritubular and perivascular space compared with patients with obstructive azoospermia. Moreover, the lower number of RCs could imply their utilization by LCs in testosterone production.

RESUMO

A small bowel prolapse through the vaginal introitus after a transvaginal instrumental gravid uterus perforation is a surgical emergency. To define the mechanisms of an irreversible, small bowel ischaemia due to small bowel prolapse through a vaginal introitus, ClinicalTrials.gov, PubMed, PubMed Central, and Google Scholar were searched. Out of the 81 articles screened, 28 cases of a small bowel evisceration through vaginal introitus were included. A small bowel obstruction severity grading was defined with risk factors; potential mechanisms of different severity grades after a transvaginal instrumental gravid uterine perforation with a vaginal evisceration. The duration of symptoms or a delay in the diagnosis did not change the incidence of the two most severe grades-mesenteric stripping and a small bowel degloving. Both obstruction types develop immediately during an instrumental abortion. The severity of obstruction does not influence the maternal outcome.

RESUMO

The aim of the review is to establish sexual and reproductive functions in men with spinal cord lesion (SCL). Many sexual and reproductive dysfunctions may be found in these patients including individual's low self-esteem, delay of orgasm, erectile or ejaculatory disorder and abnormalities of semen, which are characterized by lower sperm motility or viability. Owing to improvements in physical medicine and rehabilitation, the focus has been shifted from keeping patients alive towards ensuring the quality of life and improvements of sexual dysfunctions and later reproduction. Erectile dysfunction can be treated by using phosphodiesterase-5 inhibitors, intracavernosal injections, vacuum devices and penile prostheses. Semen can be retrieved from anejaculatory patients by medically assisted methods utilizing penile vibratory stimulation, electroejaculation, prostate mas-sage, or surgically. Although there is low chance for pregnancy in natural way in most of SCL pa-tients, fatherhood is possible through the introduction of assisted medical management. By use of various medical, technical and surgical procedures for sperm retrieval combined with assisted reproductive methods, high pregnancy rates have been reported comparable to those in able-bodied subfertile patients. Nevertheless, future studies are needed to improve semen quality and methods of assisted ejaculation in patients with SCL.

RESUMO

Expression pattern of the Ki-67, caspase-3 and matrix metalloproteinases-9 (MMP-9) factors were immunohistochemically analyzed in 48 human fetal lungs from 12 to 40 weeks of gestation. The number of Ki-67 positive cells in the epithelium of canaliculare (88cells/mm(2)) and sacculare stage (93cells/mm(2)) were significantly higher than in the epithelium of pseudoglandular stage (12cells/mm(2)) (p=0.0008 vs. p=0.003). The number of Ki-67 positive cells in the mesenchyme of canaliculare stage (132cells/mm(2)) was significantly higher than in the mesenchyme of pseudoglandular stage (37cells/mm(2)) (p=0.001). The proliferation of mesenchymal cells was higher than the epithelial cells in all developmental stages, especially in the canaliculare stage (p=0.007). Similarly, the number of caspase-3 positive cells in the epithelium of canalicular stage (13cells/mm(2)) was significantly higher than in the epithelium of pseudoglandular stage (6cells/mm(2)) (p=0.002) with peaks in the conductive epithelium of canalicular stage. The number of caspase-3 positive cells in the mesenchyme of canaliculare stage (3cells/mm(2)) was significantly higher than in the mesenchyme of saccular stage (0cells/mm(2)) (p=0.05). There were no caspase-3 positive cells in the mesenchyme of pseudoglandular stage. However, unlike the Ki-67 expression, mesenchymal cells in comparison to epithelial cells express substantially less caspase-3 in all developmental stages. Up to the saccular stage, the expression of MMP-9 in mesenchymal cells showed a linear increase with most pronounced expression in that stage. The number of MMP-9 positive cells in the mesenchyme of canaliculare (20cells/mm(2)) and sacculare (39cells/mm(2)) stage were significantly higher than in the mesenchyme of pseudoglandular stage (12cells/mm(2)) (p=0.04 vs. p=0.004). The first epithelial cells that express MMP-9 were present only at the alveolar stage. Increased proliferation and apoptosis of the mesenchymal cells of canalicular stage is important for formation of definite structures within the stroma of the lung parenchyma. Although apoptosis in the epithelium is not pronounced as proliferation, it is important for thinning of the epithelium and consequent spread of respiratory tract. However in the saccular stage when mesenchyme disappears, MMP-9 expression is more important for primitive alveoli differentiation.

RESUMO

We report a rare case of synchronous bilateral breast cancer in 79-year-old female patient treated at our hospital. The tumors were discovered one year ago after a complete clinical and radiological (mammography, US) examination with cytopunction of tumor masses. Results came back and showed carcinomas of both breasts. Patient underwent surgical re moval of the both breasts with bilateral axillary lymphadenectomy. Later histological examination confirmed earlier diagnosis of invasive ductal carcinoma in both breasts in a G3 stage. After surgical removal of the tumors patient was also treated with radiotherapy. One year after bilateral mastectomy and axillary lymphadenectomy, clinical and radiological examination that included mammography and ultrasound of breast with tumor marker C15-3 which was 2.8, we did not found recurrence of the tumor.

RESUMO

OBJECTIVE: To determine the degree of anxiety and depression in patients hospitalized at the Department of Oncology of the Mostar University Clinical Hospital and the relationship between the degree of anxiety and depression, sex, marital status, age, and education of the patients. PATIENTS AND METHODS: The study included 160 patients who were divided into two groups: a test and a control group. A patient from the test group was assigned a patient from the control group according to his/her age, gender, education level and marital status. The study population consisted of 80 patients who were treated at the Department of Oncology of the Mostar University Clinical Hospital from January 1, 2010 to March 31, 2010. The control group consisted of 80 patients who were admitted via the Family Medicine Office of the Mostar Community Health Center from March 1, 2010 to March 31, 2010. The Beck's Anxiety and Depression scale was used. The appropriate statistical methods were used to test the collected data. RESULTS: Patients hospitalized at the Department of Oncology had a greater degree of depression than the control group (exact test, P<0.001). A significant difference in the level of anxiety between the test and control groups was not found (exact test, P=0.143). A mild degree of anxiety was found in the cancer patients older than 60 and a high level of anxiety in the group aged 25-40 (exact test, P<0.001) and in highly educated patients (exact test, P=0.024). The research showed that the cancer patients from the younger age group had higher levels of depression (exact test, P<0.001). By comparing the degree of anxiety to the age in the control group, statistically significant difference was not found, so the highest level of anxiety was found in the patients aged between 41 and 60 (exact test, P<0.001). It was determined that a higher percentage of women (exact test, P=0.034) and patients over 60 years old (exact test, P=0.006) in the control group were more depressed. CONCLUSION: Although a statistically higher level of depression was determined for the test group patients, a statistically significant difference in the levels of anxiety between test and control groups was not found.
