RESUMO

Chondromas are benign cartilaginous tumors and rarely develop in the nasal septum. Although it causes different symptoms depending on the location and size of the tumor, the most common complaints are nasal obstruction and epistaxis. A submucosal mass narrowing the nasal passage can be seen in the septum by an endoscope. Computed tomography gives information about the localization and size of the mass. A definitive diagnosis is made by histopathologic examination. Treatment is surgical excision. Endoscopic surgery provides a less invasive and successful treatment. This case series aims to share that 2 cases with a diagnosis of nasal septal chondroma were successfully treated with endoscopic surgery.

RESUMO

Sudden idiopathic hearing loss (SIHL) is defined as sensorineural hearing loss at 30 dB or more at 3 consecutive frequencies that begins within 72 hours, and the etiology of the disease is still unclear. Steroid treatment is used as systemic and local (intratympanic) in sudden hearing loss, and different results have been reported for both treatment modalities. This study aimed to compare the results of the treatment in patients who received systemic steroid (SS) therapy and in patients who received systemic and intratympanic steroid (ITS) therapy for SIHL. In all, 169 patients who were admitted to our clinic with the diagnosis of SIHL between January 2007 and June 2018 were randomly divided into 2 treatment groups according to their admittance day, such as patients who received only SSs and patients who received SSs and ITSs. The results of these 2 treatment protocols were investigated. Statistical analysis was performed for all patients by grouping many factors that could be effective in prognosis, such as age, sex, and time of initiation of treatment. No differences were found between the SS group and the combined systemic-ITS group in treatment success. It was determined that being under 15 years of age, over 60 years of age, starting treatment after 7 days, vertigo, high initial hearing loss, descendant type, and total loss type in the audiogram configuration are poor prognostic factors. Being between 16 and 59 years of age, starting treatment within 7 days, having no vertigo, mild hearing loss, and having ascendant and plateau type in audiogram configuration are good prognostic factors. We observed that adding ITS treatment to SS treatment as an initial treatment did not provide any extra benefit. However, prospective, randomized, controlled studies will clarify the topic.

RESUMO

OBJECTIVE: This study aims to evaluate the demographic characteristics, indications for surgery, clinical follow-up results and complication rates of pediatric patients who have received a Paparella Type 1 tympanostomy tube (TT) insertion. METHODS: Retropective review of 816 ears of 442 pediatric patients who received Paparella type 1 tympanostomy tube insertions was performed. The patients' age, indication for surgery, middle ear effusion, time to extrusion and postoperative complications were analyzed retrospectively. Ears operated for chronic otitis media with effusion (COME) and recurrent acute otitis media (RAOM) were included in the study. Ears that underwent tympanostomy tube insertion for middle ear atelectasis and suppurative complications of acute otitis media were excluded from the study. Ears with middle ear effusion mucoid and serous were included. Ears without middle ear effusion or with purulent effusion were excluded from the study. Patients with a cleft palate, Down syndrome, craniofacial anomalies and those without regular follow-up until their tubes were extruded, were excluded from the study. RESULTS: The mean age of surgery was 5.11 years. 54.3 % of the patients were male and 45.7 % were female. 734 (90 %) tube insertions were performed for patients with COME and 82 (10 %) for those with RAOM. Mucoid middle ear effusion was observed in 86.9 % and serous in 13.1 %. The mean extrusion time of the tubes was 7.16 months. 93.1 % of the tubes were extruded spontaneously within 1 year and 99.9 % within 2 years. Postoperative complications of patients that were included were 8.7 % with otorrhea, 7.7 % premature extrusion, 8.2 % tube occlusion, 0.2 % displacement into the middle ear, 8.2 % tympanic membrane changes (5.4 % sclerosis, 2.3 % retraction and 0.5 % atrophy), 1.2 % permanent perforation, 0.1 % cholesteatoma and 0.1 % retained their tube. Premature extrusion was found to be significantly higher in the RAOM group compared with the COME group (p = 0.042). Tube extrusion time did not affect tympanic membrane changes (p = 0.061). CONCLUSIONS: Complication rates after Paparella Type 1 tube insertion are low. The incidence of complications such as otorrhea and tube occlusion were not significantly different between the indication and middle ear effusion groups. Compared to COME group, premature extrusion were found more frequently in the RAOM group. Complications of displacement into the middle ear, permanent perforation, cholesteatoma and retained tube were much rarer.

RESUMO

We investigated the effectiveness of N-acetyl cysteine (NAC) and curcumin, which have known antioxidant and anti-inflammatory effects, in reducing acoustic trauma. We randomly divided 40 adult male rats into four groups: a control group (group 1), a curcumin group (group 2), a NAC group (group 3), and an ethyl alcohol group (group 4). The rats were exposed to 110 dB sound at a frequency of 4 kHz for 2 h to simulate acoustic trauma. Group 1, group 2, group 3, and group 4 received 1 ml saline, 200 mg/kg curcumin, 350 mg/kg NAC, or 1 ml ethyl alcohol, respectively, intraperitoneally 30 min before and 24 and 48 h after acoustic trauma. Distortion product otoacoustic emissions (DPOAEs) were recorded before and after the acoustic trauma, and 72 h after drug administration. In group 2, signal-to-noise ratio (SNR) values in frequencies of 1000 Hz, 1500 Hz, and 4000 Hz decreased in the second measurements when compared to the first, and showed improvements in the third measurements in comparison to the second ones. In group 3, SNR values decreased in the second measurements, but only the values at 6000 Hz were found to be statistically significant (p = 0.007). The values in the third measurements were statistically significant when compared to the second ones. There was a statistically significant difference in the third measurements in both groups 2 and 3, possibly due to curcumin and NAC treatment. This study showed that curcumin and NAC may be effective against noise-induced hearing loss.

RESUMO

INTRODUCTION: Facial nerve damage is a condition that causes functional, psychological, and cosmetic problems; and treatment methods need to be improved. OBJECTIVE: We investigated the efficacy of titanium-prepared platelet-rich fibrin as a healing enhancer at the region of transection of the facial nerve. METHODS: Twenty-seven New Zealand male rabbits were used in this study, divided into three experimental groups. Group 1, the sham group (n=7); Group 2, the suture group (n=10); and Group 3, the suture+T-PRF group (n=10). In Group 1, the facial nerve trunk was dissected, and no additional surgical intervention was performed. For Group 2, a transection was made to the facial nerve trunk and the nerve endings were sutured together. In Group 3, nerve endings were sutured after transection, and a titanium-prepared platelet-rich fibrin membrane was wrapped in a tube around the damaged area. All animals were followed up weekly for the presence of corneal reflex, whisker movement and low ears. Bilateral facial electromyography was performed both preoperatively and postoperatively at the 1st, 3rd, 5th, 7th, 10th weeks. Tissue samples obtained at the 10th week were histopathologically examined, and intra-group and inter-group comparisons were performed. RESULTS: Subjects in Group showed improvement in whisker movement and ear drop one week earlier than Group 2. In Group 3, the nerve stimulation threshold required to trigger the compound muscle action potential had returned to values similar to the preoperative control values (11.31±2.16V) by 5 weeks postoperatively (12.51±3.97V), (p=0.249). CONCLUSION: Titanium-prepared platelet-rich fibrin administration contributed to partial nerve healing both on a functional and an electrophysiological level.

RESUMO

BACKGROUND AND OBJECTIVE: Pancreatic cancer is an aggressive disease with an impaired survival despite improvements in clinical management. Thus, understanding disease biology is of vital importance in order to overcome therapeutic challenges and achieve better prognosis. The purpose of this review is to outline the genetic landscape of pancreatic cancer along with its clinical implications. METHODS: We reviewed existing literature using electronic databases to outline the genetic landscape in pancreatic cancer. KEY CONTENT AND FINDINGS: This review mainly contains information on the genetic background of pancreatic cancer, mainly KRAS, CDKN2A, TP53 and SMAD4, with emphasis on the importance of understanding disease biology. CONCLUSIONS: The genetic aspects of pancreatic cancer have been well described especially with the introduction of next generation sequencing techniques. Future studies focusing on translation of these alterations in clinical application might pave the way for personalized surveillance and therapy.

RESUMO

Objectives: Nomograms and scoring systems in gastric cancers have been mainly developed based on adequate lymph node (lN) dissections. This study aimed to perform external validation of a nomogram developed for predicting overall survival (OS) in gastric cancer patients with insufficient number of examined LNs (eLNs) and to evaluate its usability as compared with the 8th American Joint Committee on Cancer (AJCC)'s Tumor-Node-Metastasis staging system. Methods: Medical records of 262 patients undergoing complete surgical resection for gastric cancers and having pathologically confirmed diagnosis were retrospectively reviewed. The study included 104 (39.7%) patients (82 males, median age, 60.3 years) with insufficient number of eLNs (<16). The 5-year OS rate was calculated using the nomogram and according to the AJCC system. Results: The median follow-up period was 37.4 months (range: 0.9-122.9). Of the patients, 69 (66.3%) died and 35 (33.7%) achieved 5-year survival within the follow-up period. The nomogram and the AJCC system predicted OS were significantly lower in patients who died than in those who achieved 5-year survival (p<0.001 for both). According to the receiver operative characteristics-curve, the area under the curve for the nomogram (0.801; 95% CI, 0.715-0.887; p<0.001) was larger than that for the AJCC system (0.754; 95% CI, 0.659-0.849; p<0.001). Conclusion: The nomogram developed for gastric cancer patients with insufficient number of eLNs (<16) was effective in predicting 5-year OS in our cohort and was superior to the AJCC system.

RESUMO

OBJECTIVE: To test the efficacy of including albumin in the Memorial Sloan Kettering Cancer Center (MKSCC) nomogram (MSKCC+A) on predicting the overall survival. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Ankara Training and Research Hospital & Ataturk Training and Research Hospital, Turkey, in 2020, on patients who were operated between 2009 and 2014 to confirm the 5-year survival results. METHODOLOGY: Patients who underwent R0 resection for colon cancer were evaluated. For each patient in the cohort, the 5-year probability of survival was calculated and compared with actual, using the AJCC (American Joint Committee on Cancer), MSKCC and MSKCC+A estimation systems obtained using logistic regression. The performance of the estimation methods was evaluated by the ROC analysis. RESULTS: Two hundred and thirty-nine patients were studied. When the patients with more than 5-year overall survival were compared, the AJCC, MSKCC, and enhanced MSKCC survival scores were significantly higher. AUC = 0.699 for the AJCC staging system, AUC = 0.702 for the MKSCC nomogram, and AUC = 0.777 when the albumin level was added to the MKSCC system. CONCLUSIONS: The use of the MSKCC overall survival nomogram in patients with colon cancer appears useful for both clinicians and patients. The prognostic power of this calculator was found to be further enhanced by including the preoperative serum albumin level as an extra variable in the nomogram. KEY WORDS: Nomograms, Neoplasm grading, Survival, Colon cancer, Serum albumin.

RESUMO

OBJECTIVE: To evaluate the surgical outcome in patients diagnosed as having rhinogenic contact point headaches (RCPH). SUBJECTS AND METHODS: Thirty-six patients (aged 17-58 years) with RCPH underwent mini functional endoscopic sinus surgery procedures. Patients' pain complaints were evaluated with a visual analog scale (VAS) both pre- and postoperatively. RESULTS: All patients reported a decrease in the intensity of pain postoperatively. Nineteen patients (52.7%) reported complete relief. The difference between the preoperative (mean 8.62) and postoperative VAS pain scores (mean 2.11) was statistically very significant (p = 0.0000). No major complications were encountered. CONCLUSION: The removal of contact points in patients with RCPH is very effective in carefully selected patients.

RESUMO

Fungus balls or mycetomas are extramucosal and noninvasive accumulations of degenerating fungal hyphae. In head and neck they may localized most frequently in the paranasal sinuses, especially in the maxillary sinus. These indolent infections are mostly caused by Aspergillus spp. In this article, we present two rare fungus ball cases: one occurring in an automastoidectomy cavity of a temporal bone and the other in a concha bullosa. Typically, both patients admitted with vague symptoms consistent with chronic infection resistant to conventional antibacterial medication.

RESUMO

Although considered a rare complication, gossypiboma continues to be a clinically important and probably more frequently encountered than reported situation. This study aimed to report a case of gossypiboma that was mistaken for a hydatid cyst in the preoperative evaluation. A 34-year-old male patient with a history of Nissen Fundoplication presented with a large mass palpable in the epigastrium and both the left upper and lower quadrants of the abdomen. Computerized tomography was reported to show a 20x18 cm cystic mass with a collapsed germinative membrane inside it. Laparotomy, which was performed with a suggested diagnosis of type 3 hydatid cyst, revealed that the mass was caused by a 30x30 cm surgical abdominal compress. We believe gossypiboma should be kept in mind in the differential diagnosis of abdominal hydatid cysts in the presence of a former abdominal operation, especially when the result of indirect hemagglutination test is negative.

RESUMO

We aimed to investigate if orbital dysmorphisms were more common in patients with long-standing and advanced nasal polyposis. A total of 42 nasal polyposis patients and 55 healthy controls were enrolled in this study. The distances between medial and lateral canthi were measured using a sliding caliper, and distances between medial and lateral orbital walls were evaluated on paranasal sinus CT scans. The results were compared using Student's t test and Mann-Whitney U test. The distance between medial canthi was found to be significantly increased in nasal polyposis patients compared to controls (P = 0.004). No difference was observed between patients and controls in terms of distances between lateral canthi, medial orbital walls and lateral orbital walls. Anatomic changes regarding orbital morphology may occur in patients with long-standing and advanced nasal polyposis. Early diagnosis and appropriate treatment is of paramount importance in the management of nasal polyposis, since significant anatomic changes leading to orbital dysmorphisms may occur in advanced and long-standing cases. Studies on larger series must be conducted to unveil the morphologic changes and genetic predisposition in nasal polyposis.

RESUMO

CONCLUSION: The study showed that surgery in the maxillary sinus can affect its development. OBJECTIVE: To quantitatively evaluate the long-term impact of sinus surgery on its development in the rabbit. MATERIALS AND METHODS: This was an experimental study performed at an academic tertiary medical center using 20 4-week-old New Zealand white rabbits. The rabbits underwent unilateral right maxillary sinus surgery. The contralateral maxillary sinus used as a control did not undergo the operation. The maxillary sinus ostium was enlarged on the operated side. Volumetric analysis of the maxillary sinus was performed 1 year post-surgery. The maxillary sinus volumes of both sides were calculated using Multidedector CT and the volumetric measurements of the operated side were compared with the non-operated side. RESULTS: Maxillary sinus development was significantly reduced on the surgical side. Maxillary sinus growth on the surgical side was determined as 87% compared with the non-surgical side.

RESUMO

Adenoid cystic carcinoma of the parotid gland is a rare and slowly growing, but highly malignant tumor. Surgical resection of a malignant parotid tumor should include resection of the facial nerve when the nerve is involved in the tumor. Facial nerve reconstruction is required after nerve resection. A 14 year-old female presented with complaints of painless enlargement of the right parotid gland and facial asymmetry. Physical examination revealed a firm mass in the region of the parotid gland as well as right facial paralysis. Biopsy obtained from the mass showed an adenoid cystic carcinoma of the parotid gland. A radical parotidectomy with a modified radical neck dissection was carried out. Grafting material for the facial reconstruction was harvested from the great auricular nerve. The proximal main trunk and each distal branch of the facial nerve were coapted with the greater auricular nerve. The patient received radiotherapy after surgery and was seen to achieve grade IV facial function one year after surgery. Thus, the great auricular nerve is appropriate grafting material for coaptation of each distal branch of the facial nerve.

RESUMO

BACKGROUND: There are varying opinions on the feasibility of the placement of synthetic materials in contaminated surgical fields. The aim of this study was to investigate the outcomes of the use of a commercially available composite mesh in the presence of abdominal infection. METHODS: Twenty-four hours after the induction of experimental peritonitis, 20 rats were randomized into 2 groups of 10 subjects. After abdominal cleansing with a second laparotomy, the abdomen was closed with running sutures in the control group and the composite mesh was applied in the experimental group before closure. The rats were followed up for findings of sepsis, mortality, and wound infection. On the 28th day, the rats were sacrificed and evaluated for abdominal infection, abdominal adhesions, and bacterial growth in the mesh and tissue cultures. RESULTS: The mortality rate was 0% and 30% in the control and mesh groups, respectively (p=0.21), and the wound infection rate was 20% and 57.1% (p=0.162). In the mesh group, the adhesions were significantly more intense (p=0.018) and significantly more microorganisms proliferated in the tissue cultures (p=0.003). CONCLUSION: The significant increase in the intensity of adhesions and bacterial proliferation, as well as the higher rate of mortality and wound infection in the mesh group indicated that this composite mesh cannot be used safely in the repair of abdominal defects in the presence of abdominal infection.

RESUMO

BACKGROUND: We present a case of recurrent meningitis in a patient with an occult skull base defect and without clinically or radiologically demonstrable rhinorrhea. CASE DESCRIPTION: A 34-year-old female patient presented with headache, fever, and cervical pain and was diagnosed with acute purulent meningitis. Her medical history revealed another meningitis episode following an upper respiratory tract infection 4 years before. She did not have any rhinorrhea complaint. Nasal endoscopy and computerized tomography with metrizamide failed to demonstrate any subclinical rhinorrhea. However, a bony defect in the cribriform plate and a submucosal nasoseptal collection of cerebrospinal fluid behind an intact septal nasal mucosa were detected in computerized tomography and magnetic resonance imaging studies. An endoscopic repair of the defect at the anterior cranial fossa was performed with a composite middle turbinate graft. CONCLUSION: We suggest that even if anamnesis and radiological evaluation do not confirm rhinorrhea, dehiscence of bony roof and additional submucosal collection of fluids should be investigated in patients with recurrent meningitis.

RESUMO

BACKGROUND: This study investigated the effects of an amino acid mixture containing arginine, glutamine, and ß-hydroxy-ß-methyl butyrate on secondary healing of ischemic wounds in a rat model (N = 18). METHODS: After the formation of a bipediculated flap on each rat, 2 full-thickness excisional skin wounds (2 × 2 cm) were created on every flap. The rats were then randomized into the control and treatment groups. Every rat received standardized rat food throughout the study. The rats in the treatment group were administered an extra 200 mg/kg of L-arginine, 200 mg/kg of L-glutamine, and 40 mg/kg of ß-hydroxy-ß-methyl butyrate per day. Wound sizes were measured on days 0, 4, 10, and 14. The rats were sacrificed, and the wounds were excised for biochemical and histologic examination on the 14th day. RESULTS: As compared with the control group, the treatment group's wound sizes were significantly smaller on days 10 and 14 ( P < .001), as was its inflammatory cell accumulation score ( P = .008). There was no significant difference between the 2 groups in collagen accumulation ( P = .340), granulation tissue maturation ( P = .161), angiogenesis ( P = .387), or reepithelialization ( P = .190) and no significant difference between hydroxyproline concentrations in wounds ( P = .287). DISCUSSION: This amino acid combination seems to have a positive impact on the secondary healing of experimental ischemic wounds when introduced as a supplement to the standard diet, and the reduction in the inflammatory process appears to play a role in this effect.

RESUMO

OBJECTIVE: Although many surgical patients face postoperative problems due to a poor nutritional status, there is evidence that many cases of malnutrition still go unnoticed and untreated in surgical wards. This study aims to define the current attitudes of surgeons toward nutritional screening and support. MATERIAL AND METHODS: A questionnaire with 13 questions was e-mailed to 1500 surgeons. Cross-queries were made over the responses. RESULTS: The response rate was 20.9%. Most of the respondents (89.5%) implemented nutritional screening. However, only 24.6% of these surgeons screened every patient for malnutrition. The time to initiate nutritional support varied among respondents, and only 25.5% started nutritional support early enough prior to surgery. Only 9.9% of respondents implemented evidence based practices for preoperative fasting, and 21.2% preferred immunonutrition products for patients undergoing major abdominal surgery for cancer. The responses of surgeons, who participated in at least one scientific meeting on nutrition per year, were more coherent with the nutrition guidelines. CONCLUSIONS: The results of this study reveal that the awareness and knowledge of clinical nutrition need improving amongst surgeons. To increase this awareness and knowledge, continuous learning throughout their career seems essential.

RESUMO

Concha bullosa is the most common anatomic variant of the middle turbinate. It remains usually asymptomatic. Pyocele occurs when concha bullosa becomes infected. In the formation of a pyocele, middle turbinate may become expanded and occupy the surrounding structures with local bone destruction. Direct extension of mass from the nose into the orbit may occur, because the orbital contents are separated from the ethmoidal labyrinth only by the thin lamina papyracea. We report a case of concha bullosa pyocele with orbital extension. Orbital involvement is also associated with ocular functional loss. In this case, ocular motion and vision remained normal despite of the presence of orbital extension for 2 years.
