Endoscopic Optic Nerve Decompression in a Hamamy Syndrome Patient With Bilateral Optic Canal Stenosis.

Hamamy Syndrome is an autosomal recessive syndrome with craniofacial, neurological, and osteological implications. Patients most commonly present with repeated long fractures however, other affected systems with their respective clinical presentations warrant a thorough reporting and understanding of this genetic disorder. Herein, the authors, present a 21-year-old male patient diagnosed with Hamamy Syndrome with bilateral stenosis of the optic canals and associated bilateral vision loss. This case report documents the patient's initial presentation 6 years ago, which included a history of right vision loss for 2 months, followed by a 6-year follow-up period during which the patient underwent 3 optic nerve decompression surgeries. There is currently a limited number of reports in the English literature on Hamamy Syndrome, with the primary focus being on genetic, dental, orthopedic, and neuropsychiatric aspects, but the neural foraminal narrowing with associated neuropathy has never been reported.

Comparison of the clinical outcomes of patients with NSAID-exacerbated respiratory disease receiving aspirin or biologicals.

OBJECTIVE: NSAID-exacerbated respiratory disease (NERD) is characterized by exacerbation of respiratory symptoms after NSAID intake. While research for specific treatment options continues in patients who cannot tolerate or are unresponsive to aspirin treatment after aspirin desensitization (ATAD), biologicals have emerged as a new therapeutic option in NERD patients. The aim of this study was to compare the quality of life, and the sinonasal and respiratory outcomes of NERD patients treated with ATAD or biologicals. METHODS: Patients who have been followed up at a tertiary care allergy center and who have been receiving at least one of ATAD, mepolizumab or omalizumab for at least six months were included. Evaluations were made using sinonasal outcome test (SNOT-22), asthma control test (ACT), short form-36 (SF-36), blood eosinophil counts, need for recurrent functional endoscopic sinus surgeries (FESS), and asthma or rhinitis exacerbations requiring oral corticosteroids (OCS). RESULTS: A total of 59 patients comprised of 35 (59%) females and 24 (41%) males with a mean age of 46.1 (min-max, 20-70) years were included. The baseline blood eosinophil count was higher, and a significant decrease in blood eosinophil counts was observed in the mepolizumab group compared to ATAD group (p = 0.001, p < 0.001, respectively). At follow-up, the rate of recurrent FESS was lower in the group that received mepolizumab (p = 0.02). CONCLUSIONS: In NERD patients, mepolizumab significantly decreased blood eosinophil counts and recurrent FESS. There was no significant difference between the patients receiving ATAD or mepolizumab regarding other clinical parameters.

Age at diagnosis, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio as prognoticators in pediatric sinonasal rhabdomyosarcoma.

BACKGROUND: The relationship between pretreatment blood parameters and clinical outcomes of patients with pediatric sinonasal rhabdomyosarcomas has not been described. The purpose of this study was to determine the prognostic factors and certain laboratory parameters that affect the survival and long-term survival in pediatric sinonasal rhabdomyosarcoma. METHODS: Medical records of pediatric sinonasal rhabdomyosarcoma cases who were treated and followed up between 2004 and 2020 in Hacettepe University were retrospectively reviewed. The relationship between clinical features, laboratory parameters and survival was investigated. RESULTS: Age at the time of diagnosis, pretreatment neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) had significant effect on survival (p < 0,004, p < 0,037, p < 0,016, respectively). Survival rate was higher in patients younger than 10 (≤10 years of age) at the time of diagnosis (p = 0,004), patients with a NLR of 2 or below (≤2) (p = 0,037), and patients with a PLR of 150 or below (≤150) (p = 0,016). ≤ 10 years of age at the time of diagnosis was found as an independent prognostic factor affecting survival (hazard ratio [HR], 5382; 95 % confidence interval [CI], 1476- 19,623; P = 0,011). In addition, a pretreatment PLR of 150 or below (≤150) was found as another independent prognostic factor that affects survival (hazard ratio [HR], 4386; 95 % confidence interval [CI], 1161- 16,567; P = 0,029). CONCLUSIONS: Preoperative NLR and PLR may be important parameters to predict the prognosis of pediatric sinonasal rhabdomyosarcoma. Further research with larger patient groups are warranted.

The utility of acoustic pharyngometry in treatment of obstructive sleep apnea patients with expansion sphincter pharyngoplasty surgery.

PURPOSE: Expansion sphincter pharyngoplasty (ESP) is a common surgery for patients with obstructive sleep apnea (OSA) which aims to correct the obstruction at the palatal level. The effectiveness of ESP has been widely shown in the literature using surgical success rates, but to our knowledge, there is no research which documents the changes in the upper airway anatomy objectively. We aimed to demonstrate the effectiveness of expansion sphincter pharyngoplasty using acoustic pharyngometry. We also aimed to study the possible utility of acoustic pharyngometry in predicting surgical outcomes. METHODS: Pre- and post-operative acoustic pharyngometry and polysomnography data of patients who underwent expansion sphincter pharyngoplasty were compared prospectively. Minimum cross-sectional area (MCA) and total volume of the pharynx (TPV), apnea-hypopnea index (AHI), and surgical success rates were evaluated. RESULTS: Fifty-two patients with OSA were invited to this study, and 35 patients who agreed to participate were enrolled. All patients underwent ESP surgery. Surgical success rate was 63% according to Sher's criteria. The mean AHI of the patients decreased from 29.6 ± 16.3 to 18.3 ± 18.1. MCA increased from 1.1 ± 0.4 to 2.3 ± 0.4 cm2, and TPV increased from 21.1 ± 6.9 to 31.7 ± 5.5 cm3. Comparative analysis of the successful and unsuccessful groups yielded no significant differences between the groups concerning pre- and post-operative MCA and TPV or in mean changes in MCA and TPV achieved with the surgery. CONCLUSION: Improvement in the upper airway anatomy by expansion sphincter pharyngoplasty can be clearly demonstrated using acoustic pharyngometry. Acoustic pharyngometry findings are quite similar in patients with successful and unsuccessful outcomes; therefore, pharyngometry findings cannot be used to predict surgical success; and surgical success cannot be solely attributed to the changes in MCA and TPV.

Assessment of the relationship between polysomnography parameters and plasma malondialdehyde levels in patients with obstructive sleep apnea.

PURPOSE: The relationship of plasma malondialdehyde (MDA) with major parameters of PSG was investigated to find out if there was a correlation between these variables. METHODS: Polysomnograms were done on a total of 37 adults who do not have a history of any systemic illness, smoking, and supplement use. Plasma MDA measurements and their relationship with PSG parameters were analyzed. RESULTS: The mean MDA concentrations in patients with lower AHI values were also lower than those in the patients with higher AHI (p < 0.001). Higher predominance of apnea in patients with similar AHI values, longer mean apnea durations, O2 saturation dips to < 90%, and higher ODI values predicted higher plasma MDA concentrations. CONCLUSIONS: Higher oxidative stress measurements predicted more severe clinical picture. These findings show that oxidative stress measurement with MDA may provide a simple tool to screen patients for OSA and help select them for PSG study appropriately, if indicated.

The First Enterobacter cloacae Co-Producing NDM and OXA-48 Carbapenemases and Interhospital Spread of OXA-48 and NDM-Producing Klebsiella pneumoniae in Turkey.

BACKGROUND: The aim of this study was to investigate the occurrence of carbapenemase-producing Enterobacteriaceae. METHODS: A total of 54 carbapenem nonsusceptible Enterobacteriaceae (CRE) isolates were recovered from clinical samples sent to the Dr. Lutfi Kirdar Kartal Training and Research Hospital from the period 2011 through 2014. Forty-four isolates were Klebsiella pneumoniae (CRKP) and the other 10 were Enterobacter cloacae (CREC).The isolate identifications and antibiotic sensitivity tests were performed using a Vitek2 automatic system. The clonality of isolates was determined using rep-PCR Diversilab. Presence of blaOXA-48, blaNDM, blaVIM, blaIMP, and blaKPC genes were screened using polymerase chain reaction (PCR) with specific primers. RESULTS: CRKP were isolated from blood, urine, wounds, catheter tips, and tracheal aspirate samples; a total 44 isolates were evaluated. All isolates were nonsusceptible to ertapenem/imipenem or meropenem. Eighteen percent of the isolates were resistant to colistin. CREC were isolated from blood, urine, cerebrospinal fluid and sputum; a total of 10 isolates were evaluated. They were resistant to all carbapenems and 90% were resistant to cefoperazone/sulbactam and trimethoprim/sulfamethoxazole, and 50 - 70% isolates were resistant to gentamicin, amikacin, and ciprofloxacin. Thirty-three (75%) OXA-48 producing CRKP were identified. Thirteen (29.5%) were positive and two (4.5%) NDM-producing K. pneumoniae were co-producing OXA-48. Of the ten CREC strains tested, eight were positive for blaNDM, one isolate was positive for blaVIM and another for blaIMP genes. rep-PCR typing revealed the presence of a clonal dissemination in CRKP and CREC in the hospital. CONCLUSIONS: To our knowledge, this is the first identification of blaNDM in E. cloacae isolates in Turkey. These findings describe an interhospital spread of CRKP-producing OXA-48 and NDM carbapenemases that started in 2011. Continuous monitoring is necessary to better understand their dissemination in the hospital, which probably occurred as a result of transmission from an environmental reservoir. These findings emphasize the need for intensive surveillance and precautions.

Effects of Expansion Sphincter Pharyngoplasty on the Apnea-Hypopnea Index and Heart Rate Variability.

PURPOSE: Heart rate variability (HRV) is a noninvasive and sensitive method used to evaluate autonomic function of the heart based on specific polysomnographic parameters. This study aimed to determine the effect of expansion sphincter pharyngoplasty (ESP) on HRV and the apnea-hypopnea index (AHI) in patients with obstructive sleep apnea (OSA). MATERIALS AND METHODS: This retrospective cohort study included patients who presented to the Department of Otorhinolaryngology, Hacettepe University Hospital (Ankara, Turkey), were diagnosed with OSA, and underwent ESP. Patient medical records, including demographic data, polysomnographic findings, and HRV parameters, were reviewed. The predictor variable was the effect of ESP on the AHI and the primary outcome variables were HRV parameters. Descriptive and bivariate statistics were computed using χ2 test, t test, and Mann-Whitney U test. RESULTS: The mean age of the 28 patients (20 men and 8 women) was 43 ± 9.9 years. Surgical success (AHI, <20; 50% decrease in the AHI) was achieved in 16 patients (57.1%). The AHI decreased in 22 patients (78.6%) but increased in 6 patients (21.4%) after ESP. The ratio of low-frequency power (LF) to high-frequency power (HF) decreased significantly in the patients with successful surgery and in those whose AHI decreased after surgery (P = .02 and P = .001, respectively). For the change in the LF/HF ratio, 19 patients had a decrease in sympathetic activity, whereas 9 had an increase in sympathetic activity, after ESP. A decrease in sympathetic activity after ESP was significantly associated with surgical success and a decrease in the AHI (P = .033 and P = .001, respectively). CONCLUSION: ESP is an effective surgical option for the treatment of OSA and lowers the AHI. Successful ESP plays a role in decreasing sympathetic activity of the heart, which might be associated with a decrease in the risk of cardiovascular disease.

The status of the middle turbinate and the risk of sinusitis after endoscopic transnasal sphenoidotomy.

The objectives of this study are to evaluate the occurrence of postoperative middle turbinate lateralization and the relationship between this lateralization and the risk of iatrogenic sinusitis after endoscopic transnasal sphenoidotomy procedure. Patients who undergone endoscopic transnasal sphenoidotomy and came under the surveillance of our otorhinolaryngology department between the January of 2010 and the December of 2015 were retrospectively scanned. Among them, the patients who were evaluated with paranasal sinus computed tomography (CT) postoperatively were included in the study. The amount of middle turbinate lateralization in each patient was evaluated by comparing their routine preoperative CT image with the postoperative CT image. The air-fluid levels or soft tissue opacifications in the sinuses or obstruction of the ostiomeatal complex were accepted as the evidence of sinusitis on the images. The patients were asked questions regarding their symptoms of sinusitis on a phone interview for the statistical evaluation of their preoperative and postoperative Visual Analog Scale scores of complaints of sinusitis. The difference between preoperative and postoperative measurements was found to be statistically significant (p < 0.001, 95% CI). The middle turbinate position was lateralized in 31 patients (81.6%), medialized in four patients (10.5%), and remained unchanged in three patients (7.9%). Overall, the sinus opacification and mucosal thickening rates did not change significantly which suggested the operation did not pose patients at increased risk of sinusitis. Mean VAS scores of complaints of sinusitis did not change significantly except for sensation of facial pressure, which showed a minor but statistically significant decrease (p < 0.001). This study revealed the lateralization of the middle turbinate after transnasal sphenoidotomy. However, it seemed that this lateralization did not create a predisposing factor for the development of acute and chronic sinusitis.

Correlation between transvaginal ultrasound measured endometrial thickness and histopathological findings in Turkish women with abnormal uterine bleeding.

AIM: The present study aims to determine how transvaginal ultrasonography and histopathological examination findings are correlated in a cohort of premenopausal and postmenopausal Turkish women with abnormal uterine bleeding. METHODS: This is a retrospective review of 350 Turkish women who underwent transvaginal ultrasonography and suction curettage as a result of abnormal uterine bleeding. RESULTS: Sonographic appearance of the endometrium was normal in 244 patients (69.7%), while homogeneous thickening was detected in 47 patients (13.4%) and cystic thickening in 21 patients (6.0%). A sonographic diagnosis of endometrial polyp was made in 38 patients (10.9%). Histopathological analysis of endometrial samplings revealed proliferative endometrium (36%), secretory endometrium (24.6%), decidualization (10.9%), endometrial polyp (8.3%), endometritis (6.8%), endometrial hyperplasia (4.6%), irregular shedding (3.7%), atrophic endometrium (3.1%), endometrial cancer (1.1%) and placental retention (0.9%). The sonographic and histopathological findings correlated significantly (χ(2) = 122 768, P = 0.001; r = 0.215, P = 0.001). Approximately 51% of the women with homogeneous endometrial thickening had proliferative endometrium. Only 44.7% of the women with ultrasonographically visualized endometrial polyps had histopathologically diagnosed endometrial polyps. Nearly 57% of the women with cystic endometrial thickening had proliferative endometrium. CONCLUSION: If there is no facility for hysteroscopy or hysteroscopy-guided endometrial biopsy for women with abnormal uterine bleeding, transvaginal ultrasonography findings can be efficiently used to make a preliminary diagnosis and, thus, notify the pathologists.

Predictors of fatality in pandemic influenza A (H1N1) virus infection among adults.

BACKGROUND: The fatality attributed to pandemic influenza A H1N1 was not clear in the literature. We described the predictors for fatality related to pandemic influenza A H1N1 infection among hospitalized adult patients. METHODS: This is a multicenter study performed during the pandemic influenza A H1N1 [A(H1N1)pdm09] outbreak which occurred in 2009 and 2010. Analysis was performed among laboratory confirmed patients. Multivariate analysis was performed for the predictors of fatality. RESULTS: In the second wave of the pandemic, 848 adult patients were hospitalized because of suspected influenza, 45 out of 848 (5.3%) died, with 75% of fatalities occurring within the first 2 weeks of hospitalization. Among the 241 laboratory confirmed A(H1N1)pdm09 patients, the case fatality rate was 9%. In a multivariate logistic regression model that was performed for the fatalities within 14 days after admission, early use of neuraminidase inhibitors was found to be protective (Odds ratio: 0.17, confidence interval: 0.03-0.77, p=0.022), nosocomial infections (OR: 5.7, CI: 1.84-18, p=0.013), presence of malignant disease (OR: 3.8, CI: 0.66-22.01, p=0.133) significantly increased the likelihood of fatality. CONCLUSIONS: Early detection of the infection, allowing opportunity for the early use of neuraminidase inhibitors, was found to be important for prevention of fatality. Nosocomial bacterial infections and underlying malignant diseases increased the rate of fatality.

[Fosfomycin susceptibility of urinary Escherichia coli isolates producing extended-spectrum beta-lactamase according to CLSI and EUCAST recommendations]. / CLSI ve EUCAST önerilerine göre genislemis spektrumlu beta-laktamaz üreten Escherichia coli idrar izolatlarinda fosfomisin duyarliligi

The increasing rate of antibiotic resistance in Escherichia coli, the most common pathogen of urinary tract infections (UTIs), leads to difficulties in choosing appropriate antibiotic treatment and achieving treatment success. The aim of this study was to investigate in vitro activity of fosfomycin, presented as a favorable choice for the treatment of UTIs caused especially by extended-spectrum beta-lactamase (ESBL)-producing strains. A total of 244 E.coli strains, of them 118 were ESBL positive and 126 were negative, isolated from urine samples of inpatients and outpatients between May 2011-May 2012, were included in the study. Antibiotic susceptibilities of the isolates were determined by disk diffusion method (DDM) and ESBL production was confirmed by double-disc diffusion method according to the CLSI (Clinical and Laboratory Standards Institute) recommendations. Minimum inhibitor concentration (MIC) values for fosfomycin were detected by E-test method. Fosfomycin zone diameters and MIC values of isolates were interpreted according to the breakpoints of both CLSI and EUCAST (European Committee on Antimicrobial Susceptibility Testing). Susceptibilities of ESBL positive and negative isolates to fosfomycin and other antibiotics, and the results of fosfomycin susceptibility tests obtained by different methods were compared. The correlation between fosfomycin zone diameters and MIC values was calculated. In the study, the resistance rates of ESBL-producing isolates to ciprofloxacin, trimethoprim-sulfamethoxazole, gentamicin and amikacin were detected as 67%, 51%, 51% and 19%, respectively, while those rates were as 9%, 21%, 4% and 11%, respectively in non-ESBL producers. The difference between the two groups were found statistically significant (p< 0.001). Fosfomycin resistance of ESBL-producing and non-producing isolates were 3% and 1%, respectively, indicating no significant difference between the two groups (p= 0.356). According to fosfomycin MIC breakpoints defined by CLSI, 98.3% of ESBL-producing isolates and 100% of non-producing isolates were found susceptible to fosfomycin. According to EUCAST recommendations 98.3% of ESBL-producing isolates and 99.2% of non-producing isolates were found susceptible to fosfomycin. There was no significant difference between ESBL-positive and -negative strains according to CLSI and EUCAST recommendations (p= 0.233 and p= 0.611, respectively). When the methods were compared with each other, there were significant differences between DDM and CLSI-MIC or EUCAST-MIC (p= 0.033 and p= 0.049, respectively) and between CLSI-MIC and EUCAST-MIC (p< 0.001). There was a weak reverse linear correlation between fosfomycin zone diameters and MIC values (r= -0.138, p= 0.032). It was concluded that fosfomycin which had a high activity against ESBL-producing isolates was an appropriate alternative antibiotic in the treatment of UTIs.

Salvage Endoscopic Nasopharyngectomy for Recurrent Nasopharyngeal Cancer: an Institutional Experience.

Objective: This study aims to present the surgical and oncological long-term outcomes of patients with locally recurrent nasopharyngeal cancer (NPC) following endoscopic endonasal nasopharyngectomy (EEN). Methods: The medical records of 11 patients who underwent EEN due to recurrent NPC were retrospectively reviewed. Results: The mean age of the patient cohort, consisting of 10 males (90.9%) and one female (9.1%), was 44±13.01 years at the time of initial diagnosis. Seven patients (63.7%) had local recurrence, and four patients (36.3%) had loco-regional recurrence. The mean time to first recurrence from the initial diagnosis was 40.3 months, with a 5-year overall survival (OS) rate of 72.7% and a disease-free survival (DFS) rate of 27.3%. There were no significant differences between the concurrent chemoradiotherapy (CRT) and induction chemotherapy+concurrent CRT treatment groups in terms of DFS and OS as a first-line treatment (p=0.645). Conclusion: EEN is a viable alternative approach for selected cases of locally recurrent NPC, considering the morbidities associated with re-irradiation.

Evaluation of otorhinolaryngologic, audiologic, and genetic findings in children with cystic fibrosis: A tertiary care experience.

OBJECTIVES: To evaluate otorhinolaryngologic findings and the relationship between aminoglycoside (AG) exposure and hearing loss in paediatric patients with cystic fibrosis (cwCF). We also aimed to investigate the genetic predisposition to AG ototoxicity by screening for m.1555A>G mutations. METHODS: CwCF who underwent otorhinolaryngologic and audiologic examinations were retrospectively included. Clinical characteristics, ear-nose-throat related symptoms, and a history of ototoxic drug exposure were recorded. m.1555A>G mutations were retrospectively screened among patients with audiologic evaluations. RESULTS: Two hundred thirty-four cwCF were included in this study with a median age of 10.7 (range, 6.8-14.2) years. Nasal obstruction (14.1%) was the most common symptom. Fifty-two (22.2%) patients had chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP). There was a positive correlation between CRSwNP and the symptom of nasal obstruction (r:.234, p < .001), snoring (r:.179, p = .006), and sleeping with mouth open (r:.138, p = .034). One hundred forty-nine (63.6%) patients had audiologic evaluations; 14 (9.4%) had hearing impairment. No statistical significance existed between ototoxicity and IV AG exposure (p = .90). Six (42.8%) of 14 patients did not receive ototoxic drugs. One hundred nineteen (50.8%) patients were screened for m.1555A>G mutations, and none were detected. CONCLUSIONS: Almost a quarter of the study population had CRSwNP. Neither the relationship between AGs exposure and hearing loss nor the genetic predisposition to AG ototoxicity could be shown in cwCF.

Skull base surgery for malignant tumors: The 2nd international collaborative study (1995-2015).

BACKGROUND: The current study presents the effort of a global collaborative group to review the management and outcomes of malignant tumors of the skull base worldwide. PATIENTS AND METHODS: A total of 28 institutions contributed data on 3061 patients. Analysis evaluated clinical variables, survival outcomes, and multivariable factors associated with outcomes. RESULTS: The median age was 56 years (IQR 44-67). The open surgical approach was used in 55% (n = 1680) of cases, endoscopic resection was performed in 36% (n = 1087), and the combined approach in 9.6% (n = 294). With a median follow-up of 7.1 years, the 5-year OS DSS and RFS were 65%, 71.7% and 53%, respectively. On multivariable analysis, older age, comorbidities, histology, dural/intracranial involvement, positive margins, advanced stage, and primary site were independent prognostic factors for OS, DSS, and RFS. Adjuvant RT was a protective prognostic factor. CONCLUSION: The progress across various disciplines may have contributed to improved OS and DSS in this study compared to previous reports.

A new transnasal approach to nasolabial cyst: endoscopic excision of nasolabial cyst.

Nasolabial cyst (NC) is one of the midface lesions that are seen rarely. Nasolabial cyst is generally seen in females typically on the fourth and fifth decades and localized unilaterally. Diagnosis usually depends on clinical evaluation. Sublabial excision is the classic method, but endoscopic marsupialization is suggested in current literature. An NC that is totally excised endoscopically is introduced in this article. This is the first case of NC excised endoscopically that is described in English literature.

[A predisposing clinical condition for disseminated tuberculosis: hairy cell leukemia]. / Disemine tüberküloz için predispozan klinik durum: Tüylü hücreli lösemi.

Hairy cell leukemia (HCL), a rare and slow-progressive B-cell lymphoproliferative disease, enhances predisposition to infectious complications, especially to disseminated mycobacterial infections. Although the association between HCL and mycobacterial disease has been established, disseminated Mycobacterium tuberculosis infection has been reported only in a few case series. In this report, a disseminated tuberculosis (TB) case who had been diagnosed as HCL with histopathologic examination of the bone marrow after being investigated for the etiology of fever of unknown origin, was presented. A 56-year-old male patient who was admitted to our clinic with the complaints of three weeks' duration fever, chills, night sweats and cough was hospitalized. On physical examination, the body temperature of the patient who appeared very ill, was 39°C. Dispersed macular rash that turned pale when pressure was applied, was detected on the legs, arms and back. There were no signs of peripheral lymphadenopathy, hepatomegaly or splenomegaly. Laboratory results revealed haemoglobin 10 g/dl, white blood cell count 1000/mm3, thrombocytes 143.000/mm3, erythrocyte sedimentation rate 41 mm/h, CRP 200 mg/L, uric acid 9.5 mg/dl, AST 118 IU/L, ALT 102 IU/L and LDH 429 IU/L. Thorax computed tomography showed mediastinal and bilateral hilary lymphadenopathy. Although preliminary diagnosis was lymphoma, examination of acid-fast bacilli in three days sequential sputum samples and sputum culture for the growth of mycobacteria (Bactec MGIT 960 TB system, Becton Dickinson, Md) were performed to rule out miliary TB. Blood cultures were also performed with non-radiometric fully automated TB hemoculture bottles (Bactec TB, Becton Dickinson, Md). Sputum cultures yielded no mycobacterial growth, however M.tuberculosis growth was detected in blood culture on the 27th day of inoculation. Bone marrow biopsy revealed HCL. However the patient died on the 14th day of hospitalization. In conclusion, disseminated tuberculosis should be considered for differentional diagnosis in patients with HCL or similar hematologic malignancies since TB is endemic in Turkey.

Endoscopic Excision of the Intraosseous Hemangioma of the Nasal Bone.

An intraosseous hemangioma is a rare benign tumor of the bone. Moreover, it is rarely observed in the nasal bone. A 58-year-old female patient complained of swelling in the nasal dorsum and mild pain. CT showed a round mass with a honeycomb appearance meanwhile, MRI revealed a hypointense mass in T1 sequences and hyperintense in T2 and gadolinium sequences. Endoscopic removal of the intraosseous hemangioma was performed. No recurrence was observed in the post-op 6th-month follow-up. Supplementary Information: The online version contains supplementary material available at 10.1007/s12070-023-03729-x.

Topical Intranasal Insulin Enhances Healing of Nasal Mucosa: An Experimental Animal Study.

OBJECTIVE: Aim of this study was to evaluate the effect of topical intranasal insulin on healing of nasal mucosa in a rat model. METHODS: Forty-eight Wistar rats, weighing between 250 and 300 g and aged 10-12 weeks were used and randomized into two equal groups. 1.9 mm curette was introduced through the left nostril and 1.9 mm mucosa from the left nasal septum was curetted. Postoperatively, animals in the control group received 1 mL of physiologic saline, 3 times a day in a nasal irrigation fashion. Animals in the experimental group received 1 mL of 5 IU/mL regular insulin in saline solution. Subjects were sacrificed after 5, 10, and 15 days and macroscopic and histomorphometric evaluations were performed. RESULTS: There were no mucosal synechiae and septal perforation macroscopically. Histological examination revealed that the defect size reduction was 21% in the saline group versus 56% in the insulin group on the fifth day (p = 0.006). There was 62% defect reduction in the saline group versus 79% in the insulin group on the 10th day (p = 0.034). On the 15th day, only 67% of saline group animals had complete defect closure, whereas 100% of animals treated with insulin had complete closure (92% vs 100% mucosal defect reduction, p = 0.036). Both edema and inflammation were less in the insulin group on 15th day (p = 0.006; p = 0.023, respectively). CONCLUSION: The results from this study support the safety and efficacy of topical insulin on wound healing in the literature. This study could guide further experimental studies that examine human sinonasal wound healing.

Macrophage activation syndrome triggered by primary disseminated toxoplasmosis.

We report the case of a patient with disseminated toxoplasmosis who presented with cervical lymphadenopathies and pneumonia. Although the infection was successfully treated with co-trimoxazole, the patient developed reactive macrophage activation syndrome (rMAS). To our knowledge, this is the first reported case of rMAS triggered by toxoplasmosis in the medical literature.

Influenza B-associated encephalopathy in two adults.

Influenza virus is associated with a variety of neurological complications, of which the most commonly encountered are seizures and encephalopathy. Acute encephalitis and postinfectious encephalopathy have been reported infrequently in association with influenza A and B virus infections. We describe two previously healthy adults who presented with encephalopathy with a virologically documented influenza B infection.
