RESUMEN

PURPOSE: Periorbital edema and ecchymosis that may occur after surgery in septorhinoplasty patients who have undergone lateral osteotomy are common morbidities and are seen as the main limiting factors for the recovery process of the patients. There are many different studies in the literature about the causes of periorbital edema and ecchymosis. In this study, the authors aimed to investigate the possible relationships between the bone density and bone thickness measured in the frontal process of the maxillary bone, and postoperative periorbital edema and ecchymosis, which are suitable for the osteotomy lines that they will detect in computerized tomography. METHODS: Between January 1, 2019 and November 11, 2020, 59 patients whose nasal pathologies were determined by paranasal sinus computed tomography examination due to nasal deformity and nasal deformity and who underwent septorhinoplasty operation were included in this study. Bone density and thickness measurements were performed on the frontal process of the maxillary bone in accordance with the lateral osteotomy lines on the lateral nasal wall in each patient, right and left side. According to the bone density values measured at the point determined on the lateral osteotomy line, 2 groups were formed as "very dense" and "less dense." According to the bone thickness values of the patients, 2 groups were determined as "thick" and "thin." Thus, the authors investigated the relationship between periorbital edema and ecchymosis on the postoperative first, third, and seventh days obtained from the examination files of the patients. FINDINGS: When bone density subgroups are examined, it has been shown that the degree of periorbital edema of the patients in the "very dense" and "less dense" group categories decreased from the first day to the seventh postoperative day. The degrees of periorbital edema on the third postoperative day were statistically higher in the "less dense" group than in the "very dense" group. In the authors' study, no correlation was found between the degrees of postoperative periorbital edema and ecchymosis and bone density subgroups on other days. While an increase was observed in the periorbital ecchymosis grades of the patients in the "less dense" subgroup category from the first day to the third postoperative day, the periorbital ecchymosis grades of the patients in the "very dense" subgroup category decreased from the first day to the third day. In both subgroups, the lowest periorbital ecchymosis levels were observed on the postoperative seventh day.When bone thickness subgroups are examined, it has been shown that the degree of periorbital edema of the patients in the "thick" and "thin" group categories decreases from the first day to the seventh day postoperatively. When the bone thickness subgroups were examined, the periorbital ecchymosis degrees of the patients in the "thick" and "thin" group categories increased on the third postoperative day, while it reached the lowest level on the postoperative seventh day. There was no significant difference between the first, third, and seventh-day periorbital edema and ecchymosis conditions in the "thick" and "thin" groups. CONCLUSION: The authors observed that periorbital edema and ecchymosis that may occur after septorhinoplasty can be affected by the variable features of the lateral nasal wall bone structure. The authors conclude that the changes in the healing process can be affected by different bone density values in particular.

RESUMEN

The aim of this study was to identify the potential prognostic roles of the preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and red cell distribution width (RDW) in patients with laryngeal squamous cell carcinoma (LSCC). 81 patients who underwent surgery for the larynx carcinoma were enrolled in the study. NLR, PLR and RDW were used as outcome measures. Local recurrence was detected in 30 (37.0 %) patients and neck lymph node metastasis was detected 6 (7.4 %) patients during follow-up period. Mortality was seen in 7 (8.6 %) patients. The mean PLR in the T1 and T2 stage tumors were significantly lower than the T4 stage. The mean RDW and PLR were significantly higher in the exitus group than the survivor group. The mean NLR in the patients with local recurrence was significantly higher than the non-recurrent patients. Progression-free survival (PFS) was lower in patients with high NLR. When analyzed by the Cox regression analysis of factors affecting the local recurrence, NLR was found to significantly affect the recurrence. According to ROC analysis for mortality, NLR was not found to be a prognostic factor, although the PLR and RDW were significant prognostic factors. According to Cox regression analysis, a high PLR increases mortality 4.2 times and a high RDW 4.6 times. Although in univariate analysis MCV, RDW and tumor grade were predictors of mortality, RDW and tumor grade independent predictors were found. Further studies involving large patient groups are required.

RESUMEN

OBJECTIVE: To investigate the effect of nasal septum deviation, without obstructive sleep apnea, on sleep quality. METHODS: The present case-controlled study enrolled patients older than 16 years with nasal septum deviation who attended the Otorhinolaryngology Clinic between December 2013 and July 2014. The control group was selected from patients attending the clinic for another complaint. Sleep quality was evaluated via the Pittsburgh Sleep Quality Index, and differences between the groups were compared using the Mann-Whitney U test. RESULTS: During the study period, 55 patients with nasal septum deviation were included in the study group, and the control group consisted of 51 patients with no complaints of nasal obstruction. Compared with the control group, patients with nasal septum deviation were found to be significantly higher (P <0.05) in all parameters of Pittsburgh Sleep Quality Index. CONCLUSION: The presence of nasal septum deviation with nasal obstruction should be investigated in patients with sleep disorders. If any pathology is present, opening the nasal passages should be ensured and sleep disorders reevaluated.

RESUMEN

A 42-year-old man presented with a white plastic-like material exposed in the left medial canthal area, with a fistula and purulent discharge. He had undergone endonasal dacryocystorhinostomy 7 years earlier for left eye epiphora; he had persistent postoperative epiphora and recurrent dacryocystitis despite multiple drainage attempts and antibiotics elsewhere. Computed tomography showed bilateral enlarged cystic lacrimal sacs, with a well-defined contoured tunnel-like hole at the center of the left sac. Treatment included excision of the foreign body, which was a Griffiths' collar button nasolacrimal stent, excision of the fistula tract, and revision dacryocystorhinostomy with implantation of bicanalicular silicone stent. He recovered with no further symptoms or complications. This case highlights the importance of follow-up for removal of an implanted Griffiths' stent after dacryocystorhinostomy. Patients with recurrent dacryocystitis may benefit from a detailed history of previous surgery, careful examination, and imaging to evaluate for endogenous and exogenous foreign bodies such as lacrimal sac calculi, and retained lacrimal sac stents.

RESUMEN

Otitis media (OM) is a common health problem. Nasal airways play an important role in etiopathogenesis of OM. The aim of this study is to evaluate nasal airways by objective methods in chronic otitis media (COM) cases. The relationship between the course of the disease and nasal parameters is also investigated. Fifty-six patients who had chosen an operation for chronic otitis media were included in the study. The control group was composed of 30 healthy patients. Patients were subjected to acoustic rhinometry and rhinomanometry. Nasal airway resistance and cross-sectional area measurements were taken. The results of the COM group and the control group were compared. Cases were classified by the course of the disease such as suppurative/progressive/active and non-suppurative/inactive and the nasal parameters of these sub-groups were compared. In cases with unilateral COM, nasal cavity results from both sides were compared. The nasal airway resistance of the COM group was statistically significantly higher than the control group (p < 0.05). However, there was no difference in cross-sectional area measurements. There was no significant difference between the suppurative/progressive/active and non-suppurative/inactive groups. However, the suppurative group had higher nasal resistance (p > 0.05). There was no statistical difference between the measurements of each side in unilateral COM cases. This study found that COM cases have greater nasal airway resistance. No significant difference was found in cross-sectional area measurements so the increase in resistance may be linked to mucosal rather than structural changes. There was no evidence for a relationship between the course of the OM and nasal airway parameters.

RESUMEN

BACKGROUND: Curcumin has been shown to decrease ischemia-reperfusion (I/R) injury in kidney or brain tissues. In this study, the effects of curcumin were evaluated in skeletal muscle during I/R injury. MATERIALS AND METHODS: Hind limb ischemia was induced by clamping the common femoral artery and vein. After 4 h ischemia, the clamp of the femoral vessels of animals was taken off and the animal underwent 2 h reperfusion. We measured plasma concentrations of interleukin-1ß (IL-1ß) and tumor necrosis factor-α (TNF-α) using enzyme-linked immunosorbent assay (ELISA). The right gastrocnemius muscle was harvested and immediately stored at -30°C for the assessment of superoxide dismutase (SOD), catalase (CAT) activities, and measurement of glutathione (GSH), malondialdehyde (MDA), and protein oxidation (PO) levels. Curcumin (100 mg/kg), α-tocopherol, and normal saline (10 mL /kg1) were administered intraperitoneally 1 h prior reperfusion. RESULTS: Plasma TNF-α or IL-1ß levels increased significantly in I/R group. The plasma levels of these proinflammatory cytokines were reduced in curcumin group. Muscle tissues of I/R groups revealed significantly higher antioxidant enzyme (superoxide dismutase, glutathione peroxidase, catalase) activities, and increased levels of malondialdehyde, nitric oxide, and protein carbonyl content compared with the SHAM group. Levels of these parameters in muscle revealed significant reductions in the I/R + curcumin group compared witho the I/R group. Curcumin has more potent antioxidant activity than vitamin E in the skeletal muscle I/R. CONCLUSION: In this study, protective effects of curcumin against skeletal muscle ischemia-reperfusion injury have been revealed. We underscore the necessity of human studies with curcumin that would be hypothetically beneficial preventing skeletal muscle I/R injury.

RESUMEN

OBJECTIVES: We investigated whether the maxillary sinus plays a stimulatory role in nasal nitric oxide (NO) synthesis. Research on sinusitis and nasal polyps has found low NO levels in exhaled air and linked this to obstruction of the ostium. However, the major source of NO in exhaled air is thought to be the nasal mucosa. In this study, Streptococcus pneumoniae was applied to the maxillary sinus to investigate changes in NO synthesis of the nasal mucosa. METHODS: An experimental study was performed with New Zealand white rabbits. Three groups, pneumococcus, control and sham, were created. The maxillary sinus of the pneumococcal group was exposed to Streptococcus pneumoniae suspension. Before and after the exposure, bilateral biopsy specimens were taken from the inferior turbinate. Specimens were examined by RT-PCR for expressions of endothelial nitric oxide synthase (e-NOS) and inducible nitric oxide synthase (i-NOS). Physiological saline solution was administered to the maxillary sinus in the control group and biopsies were obtained. The sham group underwent only biopsy. RESULTS: A significant increase in i-NOS expression of tissue samples from the pneumococcal group on the same and opposite sides were detected. There was no increase in e-NOS expression in this group. The control and sham groups had no significant change in i-NOS or e-NOS expression. CONCLUSION: In the acute period after the maxillary sinus is exposed to a pathogen, i-NOS expression increases in the nasal mucosa, but endothelial NOS expression is not affected. Consequently, a combined response in the maxillary sinus and the nasal mucosa for nitric oxide synthesis is shown in the present study.

RESUMEN

Warthin's tumor is a benign salivary gland tumor of the parotid gland. Although bilateral or multicentric involvement of the parotid gland is common, extraparotid involvement is seen rarely. The nasopharynx is an unusual region for extraparotid involvement. In this article, we present a 52-year-old male case with a synchronized Warthin's tumor in the bilateral parotid gland and nasopharynx, and we discuss the clinical management of the disease.

RESUMEN

Objectives: Retrocochlear pathology associated with audiovestibular symptoms is detected in very few of the patients, and most of the internal acoustic canal magnetic resonance imaging examinations (IAC-MRIs) are either completely normal or include accompanying incidental findings (IFs). The aim of our study is to reveal the presence and frequency of IFs in IAC-MRIs, together with retrocochlear lesions. In addition, we intend to emphasize the clinical importance of these IFs. Methods: A retrospective analysis of 374 serial IAC-MRI scans. Results: Gender distribution: 201 males and 173 females. Age range: 2-82 years. Seventy-two scans (19.25%) were totally normal. Fifteen scans (4.01%) demonstrated only pontocerebellar angle findings (PCAFs). The presence of PCAF and IF was together in 57 scans (15.24%). In 230 (61.50%) of the scans, only IFs were present. The incidence of IFs in all IAC-MRIs was 76.74% (287 of 374). Critical findings that may require clinical further evaluation and examination were present in 34 scans (9.09%). IFs that did not require further examination were observed in 253 scans (67.65%). Conclusion: Various IFs can be detected with IAC-MRI that may cause similar symptoms with PCAF. And unfortunately, some of these IFs may be of very high clinical importance. All referral clinicians should know well that these audiovestibular symptoms can appear as IFs anywhere in the auditory pathway, and how they should be followed in their clinical approach.

RESUMEN

Tularemia is a disease caused by Francisella tularensis and widely seen at northern hemisphere of the world. In Turkey, oropharyngeal infections caused by a less virulent serotype F.tularensis subsp. Holarctica are more prevalent. The aim of this study was to present the results of an epidemiological research performed after the detection of tularemia cases from Biga county of Canakkale province, Turkey, in December 2009. Following the report of two tularemia suspected cases from two villages (Baliklicesme and Sinekci) of Biga, an epidemiological investigation was undertaken to inspect the situation in this area. Water samples, clinical samples as throat swabs, wound swabs and serum samples were collected. Samples were cultured on heart agar supplemented with sheep blood, cysteine and antibiotics. Cultures were incubated at 37°C in 5% CO(2) and followed for 10 days. Suspected colonies were identified by slide agglutination test using F.tularensis antisera. F.tularensis antibodies were investigated by standard tube agglutination method. Positive results obtained with agglutination test were also checked for a probable crossreaction with Brucella antibodies by Rose-Bengal test. Water and wound samples were investigated using real-time polymerase chain reaction (RT Taqman PCR; Quantica, Techne Inc, UK) with probe and primers specific for ISFtu2 gene. All of the cultures yielded negative results, however eight of 16 water samples, one lymph node aspirate and one throat sample were found positive in F.tularensis TaqMan RT-PCR test. In tube agglutination test positive antibody titers between 1:20-1:1280 were detected in 36 of 115 serum samples. Two cases with antibody titers of 1:1280 and accompanying acute clinical findings, were diagnosed as tularemia and treated accordingly. Lymphatic drainage fluid samples obtained from one of these patients yielded positive result in PCR, however clinical sample could not be obtained from the other patient. The only epidemiological linkage between these acute cases (n= 2) and the other seropositive subjects (n= 34) was the use of local water supply system. It was learned that water obtained through reverse osmosis system had been used as drinking water at Baliklicesme village. Pre- and post-reverse osmosis system water samples from Baliklicesme village and samples from water supply of Sinekci village revealed positive results for F.tularensis by PCR. Since the only epidemiological relation between these two villages was using local water supply, tularemia cases encountered in this area were attributed to a waterborne epidemic and an automatic chlorination system was set up at each water reservoir in these villages. The establishment of these preventive measures curbed the growth of the epidemic. The cases presenting with throat sore, fever, lymphadenopathy (more than 2 cm), non-responsive to beta-lactam antibiotics, should be further investigated for tularemia. This work emphasizes that systematic setup and control of water disinfection systems are crucial to prevent tularemia outbreaks. Community and related authorities should be educated about the importance of water sanitation and chlorination.

RESUMEN

BACKGROUND: In this study, we evaluated how the Merocel and nasal splint packing placed in the nose after septoplasty surgery affects the olfactory and mucociliary functions of the nose in the early period, and compared the 2 packing with each other. MATERIAL AND METHOD: The study included 60 patients with isolated septal deviation and 30 patients in the control group. The patients were randomly divided into 2 groups. Nasal splint was inserted after septoplasty in group A (n = 30). Merocel was inserted in group B (n = 30). The Sniffin sticks test and saccharin test were applied to the patients before surgery and 15 days after the surgery. The same tests were applied to the control group consisting of 30 patients and the results were compared. RESULTS: No complications, such as postoperative bleeding, submucoperichondrial hematoma, or abscess formation, were found in both groups. Mucociliary function was improved after septoplasty, and it was statistically significant, but there was no statistically significant difference between both packing groups. A statistically significant difference was found for the odor test in patients who used nasal splint packing in comparison with patients who used Merocel in the early period. CONCLUSION: The odor test showed significant differences between the 2 groups and this was statistically significant in the early period. Mucociliary function was better after surgery, but there was no statistical difference in the different nasal packing groups.

RESUMEN

OBJECTIVE: To evaluate the effectiveness of different therapies for idiopathic sudden sensorineural hearing loss and prognostic factors, and determine the most successful treatment according to the audiogram type and time from onset to treatment. METHODS: A total of 90 cases from February 2009 to January 2015 were classified under Group I oral treatment (methylprednisolone, acyclovir, betahistine-dihydrochloride, and vitamin B12); Group II oral treatment + intratympanic steroids (ITS); Group III oral treatment + hyperbaric oxygen; and Group IV only ITS. A pure tone average (PTA) improvement of less than 10 dB was assessed as "no improvement," a PTA of 10 dB or more or a 10% or more increase in the speech discrimination score (SDS) as "partial improvement," and a hearing threshold within 10 dB and SDS within 5%-10% of the unaffected ear as "full improvement." RESULTS: Overall, 32.2% patients showed full and 28.9% showed partial improvement, whereas 38.9% showed no improvement. There was no significant difference in terms of mean hearing gain between the different treatment methods. As the degree of hearing loss and time from onset to treatment increased, improvement worsened (p<0.05). Descending audiogram had lower mean hearing gains compared to other groups (p=0.014). There was no significant effect of age, sex, tinnitus and/or vertigo, and systemic disease on treatment success (p>0.05). CONCLUSION: The most important factors affecting prognosis were the time from onset to treatment, hearing loss severity, and audiogram type. Only ITS avoided side effects and reduced hospitalization. ITS in the first two weeks, followed by hyperbaric oxygen were considered as the treatment priority.

RESUMEN

OBJECTIVES: This study aims to analyze the correlation between biomarkers and risks of cervical lymph node invasion, recurrence, distant metastasis and survival regarding the clinicopathological variables in laryngeal cancers. PATIENTS AND METHODS: Forty-one patients with laryngeal cancers were examined retrospectively. The correlations evaluated between E-cadherin, Ki-67, c-erbB-2 expressions, tumor site, differentiation, the risk of cervical lymph node metastasis, perineural, perivascular, pericapsular invasion and recurrence as well as survival time. RESULTS: There was significant correlation between T-grade and the survival rates, and between pericapsular invasion and the lowest survival rates. There was no significant correlation between E-cadherin, Ki-67, c-erbB-2 expressions and clinicopathological variables of tumor. Positive correlation between strong stain of E-cadherin and Ki-67 proliferation index was determined. CONCLUSION: These markers are not reliable prognostic and predictive factors for laryngeal cancers. E-cadherin expression was protected in well-differentiated and less invasive cancers, which maintain their cell-cell adhesions whereas it was reduced in undifferentiated cancers. Positive correlation between E-cadherin and Ki-67 proliferation shows that histopathological differentiation of laryngeal cancers is maintained in spite of the high proliferation index.

RESUMEN

OBJECTIVE: Chronic otitis media (COM) is a disorder characterized by perforation of the eardrum and hearing loss following chronic inflammation of the middle ear cavity, ossicules, and mastoid cells. Eustachian dysfunction plays an important role in COM etiopathogenesis and postoperative prognosis. The determinants of postoperative prognosis are still being researched. This study aimed to research the prognostic value of acoustic rhinometry (ARM) and rhinomanometry (RMM) in COM surgery in terms of eradication of the infection after operation, graft success, and hearing gain in operated cases. MATERIALS AND METHODS: This study included 58 patients who underwent surgery with a diagnosis of COM. Patients were assessed in terms of age, gender, COM type, treatment methods used, eradication of infection, graft success, and hearing gain. ARM and RMM measurements were performed in the preoperative period. ARM and RMM values were statistically compared in terms of the existence of postoperative infection, graft success, and hearing gain. RESULTS: In terms of ARM and RMM measurements, there was no statistically significant difference between cases where postoperative infection control was assured and cases with ongoing infection; successful and failed cases in terms of grafting; or successful and failed cases in terms of postoperative hearing. When preoperative and postoperative air-bone gap averages were compared, statistically significant differences were observed. CONCLUSION: In the presence of a nasal obstruction in cases with chronic otitis, elimination of this situation is the first line of treatment. Infection control, graft success, and improvement of hearing will be possible to a greater extent in the postoperative period for patients with the nasal pathology remedied.

RESUMEN

OBJECTIVES: We aimed to investigate the effects of hesperetin as a flavanon both histopathologically and immunohistochemically on cochlear apoptosis in a rat model of cisplatin-induced ototoxicity (CIO). The evaluation of the effects of hesperetin on cisplatin-induced hearing loss was performed using distortion product otoacoustic emission (DPOAE). METHODS: Twenty-eight wistar albino rats were used in the current study. The rats were randomly divided into four groups with seven rats in each group. Group C was exposed to a single dose of cisplatin (12mg/kg) by intraperitoneal injection. Group CH received intraperitoneally cisplatin (12mg/kg) and hesperetin (20mg/kg). Group H was exposed to hesperetin (20mg/kg) intraperitoneally. The sham group (group S) received normal saline (6cc) intraperitoneally. The measurements of DPOAE and signal-noise ratios (SNR) were performed before the treatment and again on the first and 6 days after administration of the drugs. Rats were sacrificed and cochleae were dissected 10 days after drug administration. The cochlear tissue was assessed in all groups by histopathologic, immunohistochemical and TUNEL assay. In addition, serum oxidative stress markers and antioxidant parameters were analyzed. RESULTS: There was a significant difference between the basal value and the sixth day at frequencies 8.4, 9.6 and 9.96 for group C. We also found a significant difference between the first and sixth day at frequencies 7.2, 8.4, 9.6 and 9.96. On the 6th day, there were significant differences between C and S groups at all frequencies except 2.4. We showed a significant difference between C and H groups at frequencies 4.8, 6.0, 8.4, 9.6 and 9.96. There was also a significant difference between C and CH groups at frequencies 2.4, and 3.6. We found lower levels of oxidants and higher levels of antioxidants in CH group as compared to C group. C group had a significantly greater number of TUNEL-positive cells than did S, H and CH groups. The number of TUNEL-positive cells in CH group was higher than in S and H groups. There was a significant difference between the positive PCNA cells of CH group compared to S and H groups in spiral ganglion and stria vascularis. In addition, there were no positive PCNA cells in C group. CONCLUSIONS: Hesperetin may prevent ototoxicity by increased antioxidant enzymes and reduced oxidant parameters and protected against apoptosis resulting from a proliferation of cochlear cells in CIO.

RESUMEN

Oxytetracycline has been suggested as an alternate therapy for chronic recurrent sialadenitis and sialorrhea. We conducted an experimental study to investigate the sclerotic effect of this drug on the submandibular gland by histopathologic methods. Our subjects were 20 New Zealand white rabbits, which were divided into two groups of 10. The right submandibular gland of the rabbits in the active-treatment group was injected with 0.3 ml of oxytetracycline (100 mg/ml), and that of the controls was injected with saline. Four weeks after the injections, all the glands were removed. Histopathologic studies, including hematoxylin and eosin and Masson trichrome staining, were carried out. The glands were evaluated for tissue inflammation, congestion, fibrosis, edema, lipomatosis, and atrophy. To investigate apoptosis, terminal deoxynucleotidyl transferase-mediated dUTP-digoxigenin nick-end labeling (TUNEL) immunohistochemical staining was used. In the study group, inflammation (n = 9), congestion (n = 9), fibrosis (n = 6), edema (n = 6), and lipomatosis (n = 4) were observed; in the sham group, only lipomatosis was seen (n = 5). The TUNEL assay results for acinar cells were 4.51 ± 1.41% in the oxytetracycline group and 2.08 ± 1.76% in the control group (p = 0.006); the corresponding figures for the duct cells were 7.05 ± 0.87% and 3.10 ± 2.26% (p = 0.001). Based on our findings, we conclude that oxytetracycline might be a viable alternative for the treatment of chronic recurrent sialadenitis and sialorrhea. However, more research in this area is needed.

RESUMEN

Actinomycotic abscess of the thyroid gland is rare especially in childhood. In this article, we report the second pediatric case in literature, at age of 18 months. Although spread of actinomycotic infection to the thyroid gland from upper aerodigestive tract by preformed pathways such as piriform sinus fistula seems rational, it was demonstrated neither in current nor in previous cases. Therefore, further work-up such as barium swallow, which is onerous to perform in a child may be reserved for recurrent cases.

RESUMEN

The head and neck region includes many vital anatomic structures. So, diseases of this region may have a more morbid and mortal course compared to other anatomic regions. In this article, we report a patient showing various symptoms due to a suture needle which was left in the surgical region during the extraction of the left inferior molar tooth three years ago.

RESUMEN

Rheumatoid arthritis is a chronic erosive rheumatic disease that can present with polyarticular involvement. Anti-TNF-alpha drugs are used in cases that are resistant to traditional disease-modifying antirheumatic drugs (DMARDs). Anti-TNF-alpha drugs are groundbreaking drugs, the efficacy of which has been proven in the treatment of rheumatoid arthritis. However, the data concerning safety remain limited and contradictory. The risk of tuberculosis reactivation, various infections, as well as lymphoproliferative disease and/or secondary malignancy is a matter of discussion. In this report, we report a 52-year-old male patient using adalimumab for active rheumatoid arthritis who presented to our polyclinic with generalized mouth and throat sores, hoarseness, and swallowing difficulty. Candida laryngitis was detected in the laryngoscopy and culture samples. Adalimumab was discontinued, and the infection was controlled with anti-fungal treatment.
