RESUMEN

OBJECTIVE: This study aimed to investigate the efficacy of hot posterior nasal packing and hot saline irrigation in bleeding control after adenoidectomy. METHODS: A total of 130 patients scheduled for adenoidectomy were included in the study, and randomized into two groups at the beginning of the surgical operation. After adenoidectomy, saline impregnated tampon, and saline irrigation at room temperature (22 °C) was applied to the patients in one group while 50 °C saline impregnated tampon and saline irrigation at the same temperature were applied to the patients in the other group. We recorded hemostasis for up to 3 min after tamponade for bleeding control, and the amount of bleeding into the nasopharynx. RESULTS: The age of the patients ranged from 1.5 to 13 years (mean ± SD: 6.07 ± 3.08 years, and 5.33 ± 2.55 years, 22 °C and 50 °C saline irrigation groups, respectively). There were 37 males and 28 females in the 22 °C saline group, while 34 males and 31 females in the 50 °C saline group. When comparing the two groups, there was no statistically significant difference in terms of duration of hemostasis (p = 0.64). However, bleeding scores at 2 nd min after the tamponade were significantly lower in the 50 °C saline group (p = 0.007). The amount of bleeding in the 50 °C saline group was also significantly lower than the 22 °C saline group (p = 0.015). CONCLUSION: In this study, application of 50 °C saline impregnated tampon, and hot saline irrigation was found to be more effective in the control of bleeding after adenoidectomy by reducing the amount of bleeding compared to 22 °C saline impregnated tampon application and saline irrigation at 22 °C. However, hot nasal packing and hot saline irrigation did not affect duration of hemostasis and cauterization.

RESUMEN

Frontal cells appear in two locations-in the frontal recess and in the frontal sinus. The aim of this study was to analyze the anatomic and clinical differences between the frontal cells at each location. The author reviewed 487 left and right sides of coronal computed tomography (CT) scans of the sinuses obtained from 300 consecutively presenting patients (600 sides) who were being evaluated for chronic sinusitis. For the purposes of this study, the frontal cells were classified according to location; group A cells were located in the area of the frontal recess (Bent and Kuhn cell types I and II), and group B cells were those that had invaded the frontal sinus itself (Bent and Kuhn cell types III and IV). The presence or absence of frontal sinusitis and concha bullosa was determined, as was the degree of frontal sinus pneumatization. Analysis revealed statistically significant differences between group A and group B in all three parameters; the prevalence of frontal sinusitis and hyperpneumatization of the frontal sinus was higher in group B, and the prevalence of concha bullosa was higher in group A (all p < 0.05). These findings imply that it might be more reasonable both clinically and anatomically to categorize frontal cells based on their location rather than on their Bent and Kuhn type.

RESUMEN

BACKGROUND: Controlled hypotension is a technique that is used to limit intraoperative blood loss to provide the best possible surgical field during surgery. OBJECTIVE: The aim of this double-blind, randomized, controlled study was to compare the effects of desflurane combined with esmolol or dexmedetomidine on the amount of blood in the surgical field, recovery time, and tolerability in adult patients undergoing tympanoplasty. METHODS: Turkish patients aged 18 to 60 years, classified as American Society of Anesthesiologists physical status I or II, who were scheduled for tympanoplasty were randomly divided into 2 groups: the esmolol group or the dexmedetomidine group. After the anesthesia induction in the esmolol group, a loading dose of esmolol was infused intravenously over 1 minute at 1 mg/kg, followed by a maintenance rate of 0.4 to 0.8 mg/ kg/h. In the dexmedetomidine group, a loading dose of dexmedetomidine was infused intravenously over 10 minutes at a rate of 1 µg/kg, followed by a maintenance rate of 0.4 to 0.8 µg/kg/h. The infusion rates were then titrated to maintain mean arterial pressure (MAP) of 65 to 75 mm Hg. General anesthesia was maintained with desflurane 4% to 6%. Heart rate (HR) and MAP were recorded during anesthesia. The following 6-point scale was used to assess the amount of bleeding in the operative field: 0 = no bleeding, a virtually bloodless field; 1 = bleeding that was so mild that it was not a surgical nuisance; 2 = moderate bleeding that was a nuisance but did not interfere with accurate dissection; 3 = moderate bleeding that moderately compromised surgical dissection; 4 = bleeding that was heavy but controllable and that significantly interfered with surgical dissection; and 5 = massive bleeding that was uncontrollable and made dissection impossible. Scores ≤2 were considered to be optimal surgical conditions. The sedation score was determined at 15, 30, and 60 minutes after tracheal extubation using the following scale: 1 = anxious, agitated, or restless; 2 = cooperative, oriented, and tranquil; 3 = responsive to commands; 4 = asleep, but with brisk response to light, glabellar tap, or loud auditory stimulus; 5 = asleep, sluggish response to glabellar tap or auditory stimulus; and 6 = asleep, no response. Time to extubation and to total recovery from anesthesia (Aldrete score ≥9 on a scale of 0-10), adverse effects (eg, intraoperative hypotension [blood pressure <65 mm Hg], bradycardia [HR <50 beats/min]), intraoperative fentanyl consumption, and postoperative nausea and vomiting were recorded. Arterial blood gas analysis and kidney and liver function tests were conducted. All patients were evaluated by the same attending surgeon and anesthesiologist, both of whom were blinded to the administered study drugs. RESULTS: Fifty-two consecutive white patients undergoing tympanoplasty were identified. Two patients had to be excluded because of hypertension and 2 refused to participate. Forty-eight patients were equally randomized to either the esmolol group (n = 24 [16 women, 8 men]; mean [SD] age, 38.4 [10.5] years) or the dexmedetomi-dine group (n = 24 [17 women, 7 men]; mean age, 35.5 [14.7] years). Sedation scores were not collected for 1 patient in the esmolol group; therefore, analysis was conducted for 23 patients. The median (range) of the scores for the amount of blood in the surgical field in the esmolol and dexmedetomidine groups was 1 (0-3) and 1 (0-2), respectively (P = NS). Mean intraoperative fentanyl consumption in the esmolol group was significantly higher than in the dexmedetomidine group (50.0 [3.0] vs 25.0 [2.5] µg/min; P = 0.002). In the esmolol group, the mean times to extubation and to recovery from anesthesia were significantly shorter than those of the dexmedetomidine group (7.0 [1.4] vs 9.1 [1.9] minutes, respectively; 5.9 [2.1] vs 7.9 [2.3] minutes; both, P = 0.001). The mean sedation scores were significantly lower in the esmolol group (n = 23, because of intent-to-treat analysis) compared with the dexmedetomidine group at 15 minutes (2.5 [0.6] vs 3.6 [0.5]; P = 0.001) and 30 minutes (2.6 [0.6] vs 3.3 [0.6]; P = 0.001) postoperatively. No significant differences were found between the study groups in regard to blood urea nitrogen or creatinine concentration, aspartate aminotransferase or alanine aminotransferase activities, pH, partial pressure of carbon dioxide, or bicarbonate, before or after the operation. CONCLUSIONS: Both esmolol and dexmedetomidine, combined with desflurane, provided an effective and well-tolerated method of achieving controlled hypotension to limit the amount of blood in the surgical field in these adult patients undergoing tympanoplasty. Esmolol was associated with significantly shorter extubation and recovery times and significantly less postoperative sedation compared with dexmedetomidine.

RESUMEN

Paragangliomas are neuroendocrine tumors of paraganglionic tissue which are extremely rare in the sellar area. We present a case of sellar paraganglioma with parasellar and suprasellar extension in a 70-year-old man who presented with headache. CT demonstrated sellar mass with suprasellar and right parasellar extension. The lesion was removed subtotally via a trans-sphenoidal approach. Histopathological diagnosis was paraganglioma. Differential diagnosis between paragangliomas and unusual types of pituitary adenomas, especially null-cell adenomas, is made by presence of cell nests (Zellballen) in paraganglioma, lack of immunopositivity for pituitary hormones, cytoplasmic immunopositivity for chromogranin A and neuron-specific enolase, and immunonegativity for cytokeratin 19, cytokeratin 20 and endomysial antibody. In the case of a mass in the sellar region, paraganglioma, although rare, should be included in the differential diagnosis.

RESUMEN

OBJECTIVE: The aim of this study was to investigate cochlear damage in Crimean-Congo hemorrhagic fever (CCHF) infection. METHODS: Thirty-two CCHF patients (study group) and 13 healthy people (controls) were included in the study. CCHF patients were also grouped for the presence of fever. CCHF was diagnosed with the presence of CCHF virus-specific IgM antibody or CCHF virus (CCHFV) antigen by ELISA. Cochlear damage was determined by a 'fail' in the transient evoked otoacoustic emission (TEOAE) test. RESULTS: The proportion of TEOAE test 'fail' results in the CCHF patients was significantly higher than in the control group (p<0.05). We found no increase in the proportion of TEOAE test 'fail' results related to fever in the study group. CONCLUSIONS: CCHF disease damages cochlear function regardless of fever.

RESUMEN

BACKGROUND: Rhinolithiasis is a rare and under-diagnosed clinical entity whose etiology and pathogenesis is poorly understood. OBJECTIVE: The objective of the study is to review the clinical and radiologic features of rhinolithiasis and mineralogical-chemical composition of the rhinoliths with the aim of shedding light on its etiology and pathogenesis. METHODS: Our subjects consisted of 8 rhinolithiasis cases. Clinical presentations, signs, and symptoms of the patients with radiologic findings are presented, and X-ray diffraction analyses of the stones were carried out to assess their mineralogical composition. RESULTS: Nasal obstruction appeared to be the chief symptom, followed by nasal discharge and facial pain. Neither exogenous nor endogenous nidi were identified in any of the cases. Mineralogical analyses of the rhinoliths revealed Whitlockite [(Ca,Mg)3 (PO4)2] in one and Dahllite [Ca5 (PO4,CO3)3OH] in 7 cases. CONCLUSION: We hypothesized that some substances or organic objects form the nidi of the rhinoliths and are disintegrated over the course of mineral precipitation. This hypothesis was supported by radiologic and microscopic findings.

RESUMEN

BACKGROUND: We need more data about the variations of skull base to minimize the complications of ethmoidectomy. The aim of this study was to analyze the relationship between the pneumatization of the frontal sinus and height of the fovea ethmoidalis. METHODS: Paranasal coronal computed tomography (CT) scans of 487 sides of 300 patients were evaluated. The presence of the frontal cell and pneumatization of the frontal sinus were studied with respect to the height of the fovea ethmoidalis. RESULTS: We found a statistically significant correlation between the frontal cell and frontal sinus hyperpneumatization (p = 0.000). We determined that there was a deeper fovea ethmoidalis in the sides that have a frontal cell (p

RESUMEN

OBJECTIVES: Nuclear characteristics of epithelial cells in nasal polyps were analyzed. PATIENTS AND METHODS: The slides of 35 patients who underwent surgery for nasal polyposis and 18 slides of normal mucosa were examined. The specimens were stained with hematoxylin-eosin. Tissue sections were analyzed by a CCD camera and the Karyotype Program of Human Cytogenetics Nomenclature System on a Macintosh computer (OS 9). Fifty epithelial cells in each slide were randomly selected and transferred to the automated karyotyping system and photographed. The diameters of the nuclei were measured and some peculiar nuclear features were examined, including unsmooth appearance of the nuclear membrane, anaphase-bridge, and binucleation. RESULTS: There were significant differences between nasal polyp and normal mucosa groups in terms of nuclear diameter, perimeter, and volume, with all variables being greater in the nasal polyp group (p=0.001). Unusual nuclear features differed significantly (unsmooth nuclear membrane appearance, p<0.001; anaphase-bridge, p=0.041; binucleation, p=0.018), as well. CONCLUSION: Epithelial cells of nasal polyps exhibit nuclear instability.

RESUMEN

OBJECTIVES: We evaluated the correlation between the microbial content of chronic suppurative otitis media (CSOM) and regional climatic parameters. METHODS: We assessed the interrelations between monthly mean records of temperature, maximum temperature, atmospheric pressure, and humidity and the aerobic microbial flora in CSOM. RESULTS: Forty-three bacteria of Enterobacteriaceae, 67 staphylococcal spp, 51 Pseudomonas aeruginosa, 9 Streptococcus pneumoniae, 1 alpha-hemolytic Streptococcus, 1 Enterococcus sp, and 2 Edwardsiella tarda strains were recovered from 173 patients with CSOM. There was a good relationship between enteric bacteria and monthly mean temperature (r = 0.501) and significant colonization rates due to increasing monthly mean temperature (p = .040) and monthly mean maximum temperature values (p = .048). CONCLUSIONS: When the weather warmed, the frequency of isolation of enteric bacteria increased significantly. Temperature changes may affect the enteric bacterial colonization of CSOM.

RESUMEN

BACKGROUND: An animal study is performed to determine the early effect of 1% Na hyaluronate on mucociliary clearance function. METHODS: One percent of Na hyaluronate was introduced into the maxillary sinuses of rabbits by anterior antrostomy. A physiological solution of 1% NaCl was introduced into the maxillary sinuses of a control group to equalize the influence of Na for both groups. The treatment material was sprayed with an atomizer for coating the maxillary sinus lining. Technetium-99m diethylenetriamine pentaacetate dynamic scintigraphic imaging was performed to evaluate mucociliary clearance function on all rabbits 72 hours after the surgical procedure. RESULTS: Although the mean rate of mucociliary clearance of the Na hyaluronate group was slightly worse than the control group; there was no statistically significant difference between them. CONCLUSION: There is no early effect of exogenous 1% Na hyaluronate on mucociliary clearance function.
