Objective. The Onodi cell is the posterior-most ethmoid air cell and an important anatomical variant because of the intimate spatial relationship with the optic nerve, internal carotid artery, and sellar floor during sphenoid sinus surgery. The authors evaluated the incidence of Onodi cells, their clinical importance, and the association between preoperative radiological findings and surgical findings. Study Design. Case series with chart review. Setting. Tertiary care medical center. Methods. The authors retrospectively reviewed the medical records of 162 cases, including preoperative paranasal sinus computed tomography (PNS CT) findings and the findings with the endoscopic endonasal transsphenoidal approach (EETSA). They evaluated the prevalence of Onodi cells and the clinical manifestations in the patients with these cells. They also examined the clinical significance of these cells during EETSA. Results. Onodi cells were identified in the preoperative PNS CT of 53 patients, whereas Onodi cells were observed in 54 (33.3%) of the 162 patients at EETSA. The Onodi cells were bilateral in 23 patients and unilateral in 31. In all cases, the Onodi cells limited the exposure of the sellar floor. Only after removing these cells was the entire sellar floor exposed so that the tumors could be removed completely. Conclusion. Onodi cells were observed more frequently than in previous studies, and 98.1% of them were identified on preoperative PNS CT. When reviewing PNS CT images preoperatively, one needs to identify the presence of Onodi cells. The Onodi cells must be removed to completely resect tumors located in the sellar region during EETSA.

ABSTRACT Background Chronic rhinosinusitis (CRS) is diagnosed on the basis of symptoms, nasal endoscopic findings and computed tomography of the paranasal sinuses (CT PNS). Where indicated, functional endoscopic sinus surgery (FESS) is the surgical treatment. Objective To determine correlations between subjective symptom severity and objective endoscopic and radiologic findings in CRS and to compare these before and after FESS. Materials and methods Analysis of prospectively collected data of 20 patients undergoing FESS at a tertiary care medical center followed up for a minimum period of 6 months after surgery. RSI questionnaire-based symptom score, Lund-Mackay system-based endoscopic and CT finding scores were recorded preoperatively and at 8 weeks and 6 months postoperatively. Results Significant positive correlation was noted between the three parameters before surgery, especially endoscopic and radiological scores (r = 0.94 in the latter, p < 0.01 in all three). Postoperative improvement was statistically significant for all three parameters, even at the 6 months stage (p < 0.001). Postoperative correlations reduced significantly, especially between endoscopic and radiological scores. Conclusion This study showed the relevance of objective evaluation of routine parameters of CRS, preoperatively. It also confirmed the usefulness of FESS in indicated cases, in terms of statistical improvement of these parameters. However, repeat CT scans and the methods of scoring used by us may not be equally applicable in the long-term postoperative scenario. How to cite this article Deepthi NV, Menon UK, Menon IR.

Flap Viability

Objectives The pedicled nasoseptal flap (NSF) has dramatically reduced postoperative cerebrospinal fluid leakage following endoscopic endonasal approach (EEA) surgery. Although rare, its arterial supply may be damaged during harvest or may be preoperatively damaged for numerous reasons. Early recognition permits harvesting a contralateral flap before sacrificing its pedicle as part of the surgical exposure or use of an alternative flap. Design Technical feasibility study and case series. Setting Tertiary care university-associated medical center. Participants Five patients requiring an EEA with NSF reconstruction. Main Outcome Measures During NSF harvest, intravenous indocyanine green (IVICG) was administered, and a customized endoscopic system was used to visualize the emerging fluorescence. At the end of each case, just before final positioning of the NSF, additional IVICG was administered, and the custom endoscope was again introduced to evaluate fluorescence. Results In four patients, the entire NSF fluoresced brightly with IVICG on initial harvest and before final positioning. One patient showed heterogeneous fluorescence of the pedicle and distal parts of the NSF at both stages. All NSFs healed well without complication. Conclusion IVICG facilitates real-time evaluation NSF's arterial supply. This may provide early recognition of arterial compromise, allowing the harvest of alternate flaps or modification of surgery.

Objective To identify the sociodemographic characteristics and risk factors associated with suspected foreign bodies in the ear, nose, throat, airway, and esophagus among Polish children. Study Design Case series with chart review. Setting Tertiary care medical center. Subjects and Methods A retrospective analysis of the medical records of patients hospitalized for a suspected foreign body (FB) between 1998 and 2008 was conducted. Data regarding place of residence, presence of siblings, parents’ educational status, seasonality, psychomotor development, age, and sex were collected and statistically analyzed. Results Of the 1011 patients with suspected foreign body insertion, 849 (84%) had a positive diagnosis. Of the confirmed foreign bodies, 96 were found in the tracheobronchial tree, 142 were found in the esophagus, and 611 were located in the external auditory canals, nasopharyngeal passage, tonsils, auricles, or lips. Sociodemographically, 596 of the children came from urban areas, with a preponderance of males (55%). Objects were removed more frequently in summer and autumn (60%). Children with siblings (53%) predominated. The majority of patients (52%) had parents with an elementary education. Food was the most frequent foreign body in children under 3 years of age. Patients with delayed psychomotor development constituted 1.6% of the analyzed population. Conclusions Being male, 1 to 3 years of age, belonging to an urban family with siblings, and having parents with an elementary education increased the risk of foreign body insertion. Training caregivers about proper nutrition and safety rules when playing with children can reduce the risk of accidents related to foreign body insertion.

Introduction: Multidrug-resistant strains of Acinetobacter pose a serious therapeutic dilemma in hospital practice, particularly when they cause meningitis, as the few antimicrobial agents to which these isolates are susceptible have poor central nervous system (CNS) penetration.  Methodology: We retrospectively reviewed the clinical course and outcome of eight consecutive cases of meningitis due to Acinetobacter spp. in children ages 15 years or less, seen in a tertiary care medical center in Karachi, Pakistan. Results: Of the eight cases of Acinetobacter meningitis, isolates from five patients were pan-resistant, and two were multidrug-resistant. A neurosurgical procedure was performed in five of eight patients followed by external ventricular drain insertion prior to the development of infection. Seven received intravenous (IV) polymyxin (mean; 12.8 days), while 5/8 also received intrathecal (IT) polymyxin (mean; 12.0 days). The mean length of hospitalization was 38.7 ± 19 days. All patients achieved cerebrospinal fluid (CSF) culture negativity by the end of treatment (mean; 5.4 days). Two patients died: one with pan-resistant Acinetobacter, and the second with a multi-drug resistant isolate. Conclusion: Post-neurosurgical multidrug-resistant and pan-resistant Acinetobacter meningitis can be successfully treated if appropriate antimicrobial therapy is instituted early. The role of IT polymyxin B administration alone versus combination therapy (IV and IT) needs further study.

OBJECTIVE To evaluate the effectiveness of octreotide acetate in the treatment of refractory bone marrow transplant—associated diarrhea. DESIGN Case series encompassing 30 months. SETTING A 12-bed bone marrow transplant unit at a tertiary care medical center. PARTICIPANTS Twenty-four patients with bone marrow transplant—associated diarrhea who did not improve with supportive or attapulgite therapy. INTERVENTIONS Patients received subcutaneous octreotide acetate at doses ranging from 50 to 250 μg 2 to 3 times daily. Concurrent treatment with antimotility or antisecretory agents did not occur. MAIN OUTCOME MEASURES The number of bowel movements and stool volumes were recorded daily. Complete response to octreotide therapy was defined as a reduction of both stool output and stool frequency by more than 50% within 72 hours. Partial response was defined as a reduction of either stool output or stool frequency by more than 50% within 72 hours. Treatment failure occurred if neither of the two parameters decreased by 50% within the designated time period. RESULTS Twenty-eight treatment challenges were initiated in the 24 patients evaluated. Diarrhea completely or partially subsided in 23 of 28 challenges (82.1%) within 72 hours. Stool output decreased from 1143 ± 595 at baseline to 252 ± 356 mL/d within 72 hours (p < 0.005). Stool frequency decreased from a baseline of 7.5 ± 3.4 to 2.7 ± 2.2 stools per day within 72 hours (p < 0.005). Adverse effects associated with octreotide were pain or burning at the injection site (24.1%), abdominal pain (13.8%), and increased stool output (6.9%). CONCLUSIONS These data suggest octreotide acetate significantly reduces stool output and frequency in patients with refractory bone marrow transplant—associated diarrhea. Additional research is necessary before this agent can be recommended for routine use in this patient population.

Objective Few studies have investigated pharyngeal intraluminal baseline impedance (BI) levels in patients with laryngopharyngeal reflux (LPR). The aim of this study was to compare intraluminal BI levels between patients with LPR and healthy controls. Study Design Retrospective case series. Setting Tertiary care medical center. Subjects and Methods We conducted a retrospective analysis of 24-hour multichannel intraluminal impedance (MII)–pH monitoring results from patients with suspected LPR complaining of reflux symptoms. Patients with suspected LPR were divided into 2 groups according to the 24-hour MII-pH monitoring (LPR group: patients with symptoms with reflux events ≥1, symptom but no reflux [SNR] group: patients with symptoms but no reflux event). Healthy controls were recruited and also underwent 24-hour MII-pH monitoring. We compared the esophageal and pharyngeal BI levels and ratios between 3 groups. Results Pharyngeal BI levels in the LPR group were significantly higher than in the healthy controls. In addition, the pharyngeal BI levels in the SNR group were significantly higher than in the healthy controls. All ratios of pharyngeal to distal esophageal BI levels in the LPR and SNR group were significantly higher than in the healthy controls. However, there were no significant differences in esophageal BI levels and ratios between the 3 groups. Conclusion We found that the pharyngeal BI levels were higher in patients with LPR than in healthy controls. In addition, the pharyngeal BI levels measured by 24-hour MII-pH monitoring in patients with LPR symptoms, but without a reflux episode, were higher than in the healthy controls.

AbstractObjective:To characterize the epidemiology of invasive pulmonary aspergillosis (IPA).Design:A retrospective case series.Setting:An 850-bed, academic, tertiary-care medical center.Participants:Adult inpatients, between January 1, 1990, and December 31, 1998, with either a histopathology report consistent with IPA or a discharge diagnosis of aspergillosis.Methods:We reviewed medical records and categorized case-patients as definitive or probable and acquisition of IPA as nosocomial, indeterminate, or community using standard definitions. To determine the rate of aspergillus respiratory colonization, we identified all inpatients who had a respiratory culture positive for Aspergillus species without a histopathology report consistent with IPA or a discharge diagnosis of aspergillosis. Three study intervals were defined: interval 1,1990 to 1992; interval 2,1993 to 1995; and interval 3,1996 to 1998. Carpeting in rooms for patients following heart-lung and liver transplant was removed and ceiling tiles were replaced during interval 1; a major earthquake occurred during interval 2.Results:72 case-patients and 433 patients with respiratory colonization were identified. Acquisition was nosocomial for 18 (25.0%), indeterminate for 9 (12.5%), and community-acquired for 45 (62.5%) case-patients. Seventeen (23.6%) of the 72 case-patients had prior transplants, including 15 solid organ and 2 bone marrow. The IPA rate per 100 solid organ transplants (SOTs) decreased from 2.45 during interval 1 to 0.93 during interval 2 and to 0.52 during interval 3 (chi-square for trend, 5.44; P<.05). The hospitalwide IPA rate remained stable at 0.03 per 1,000 patient days.Conclusions:The SOT IPA rate decreased after intervals 1 and 2, although the hospitalwide IPA rate remained stable during the study period. Post-earthquake hospital demolition and construction occurring after interval 2 was not associated with an increase in the rate of IPA at our institution.

Abstract: Objective: Sacrificing the auricle has severe postoperative impacts on patients with temporal bone malignancy who have undergone en bloc temporal bone resection. The auricular complications following en bloc temporal bone resection remain unclear. Therefore, this study aimed to examine auricular complications following en bloc temporal bone resection and reveal the associated risk factors. Study Design: Case series with chart review. Setting: Single tertiary care medical center Participants: Our study includes all cases who underwent en bloc temporal bone resection with preserved auricle for temporal bone malignancy from January 1993 to July 2020. The resulting dataset contained 64 patients during the review period. Main outcome measures: We examined the relationship of auricular complications with surgical procedures and patient profiles. Results: Three of 64 cases (4.7%) showed postoperative auricular complication. The cause in all three cases was venous congestion. Postoperative bloodletting to relieve the congestion effectively salvaged the auricle in two of these cases. Insufficient bloodletting to relieve the auricular congestion in the remaining case led to auricular necrosis. Pre-/infra-auricular lymph node dissection is correlated with auricular complications with statistical significance. Conclusions: Temporal bone resection causes auricular congestion due to vascular insufficiency, particularly insufficient venous outflow. An immediate and continuous application of bloodletting can improve venous drainage after temporal bone resection to prevent auricle necrosis.

Abstract Background and study aims There are conflicting data regarding the risk of post-ERCP pancreatitis (PEP) with self-expandable metallic stents (SEMS) compared to polyethylene stents (PS) in malignant biliary obstructions and limited data related to benign obstructions. Patients and methods A retrospective cohort study was performed of 1136 patients who underwent ERCP for biliary obstruction and received SEMS or PS at a tertiary-care medical center between January 2011 and October 2016. We evaluated the association between stent type (SEMS vs PS) and PEP in malignant and benign biliary obstructions. Results Among the 1136 patients included in our study, 399 had SEMS placed and 737 had PS placed. Patients with PS were more likely to have pancreatic duct cannulation, pancreatic duct stent placement, double guidewire technique, sphincterotomy and sphincteroplasty as compared to the SEMS group. On multivariate analysis, PEP rates were higher in the SEMS group (8.0 %) versus the PS group (4.8 %) (OR 2.27 [CI, 1.22, 4.24]) for all obstructions. For malignant obstructions, PEP rates were 7.8 % and 6.6 % for SEMS and plastic stents, respectively (OR 1.54 [CI, 0.72, 3.30]). For benign obstructions the PEP rate was higher in the SEMS group (8.8 %) compared to the PS group (4.2 %) (OR 3.67 [CI, 1.50, 8.97]). No significant differences between PEP severity were identified based on stent type when stratified based on benign and malignant. Conclusions PEP rates were higher when SEMS were used for benign obstruction as compared to PS. For malignant obstruction, no difference was identified in PEP rates with use of SEMS vs PS.
