Objective: To determine the accuracy of preoperative MRI in predicting cochlear obstruction in pediatric patients with a history of bacterial meningitis. Methods: A case series with chart review was performed at a tertiary care multidisciplinary cochlear implant program. Forty-five children with hearing loss that resulted from bacterial meningitis were implanted from 1991 to 2006. Twenty-five children had preoperative MRI with high-resolution axial T2-weighted images to assess for cochlear patency. Results: Seventeen of 25 patients (68%) had surgical evidence of cochlear obstruction. Six patients (37.5%) required circummodiolar drill-outs, and one patient (6.25%) underwent placement of a double array cochlear implant. The nine remaining patients (56%) with cochlear obstruction required removal of fibrous tissue or drilling of the inferior basal turn, but did not require manipulation of the ascending basal turn to achieve full electrode insertion. The sensitivity, specificity, and positive and negative predictive value of MRI predicting intraoperative cochlear obstruction with 95 percent confidence intervals was 94.1 percent (71–99), 87.5 percent (47–99), 94.1 percent (71–99) and 87.5 percent (47–99), respectively. Conclusion: Preoperative high-resolution T2 MRI may be useful in predicting cochlear obstruction in patients with a prior history of bacterial meningitis.

Objective 1) To determine pediatric cochlear implant performance outcomes for hearing loss secondary to bacterial meningitis. 2) To determine if a performance difference exists in pediatric cochlear implant patients with and without labyrinthitis ossificans. Methods A retrospective case review was performed at a tertiary care multi-disciplinary cochlear implant program. 45 children were implanted from 1991 to 2006 whose hearing loss resulted from bacterial meningitis. Mode of communication, school placement and performance were reviewed. Results 21 patients(52%) were in a mainstream educational enviroment and 19 (48%) were in a special needs enviroment. 24 subjects (58%) used an auditory-verbal mode of communication, while 17 (42%) used total communication. The mean speech reception threshold was 28dB with a range from 5 to 65dB. 14 subjects (56%) had labyrinthis ossifcans, while 11 subjects (44%) did not. Conclusions The present study demonstrated that over half of our subjects developed labyrinthitis ossificans. Despite the presence of cochlear ossification, patients with bacterial meningitis-induced hearing loss can often perform in a main-stem classroom with auditory-verbal communication.

AbstractIntroduction:Chorda tympani injury as a complication of middle-ear surgery has been extensively studied with regard to its effects upon taste. However, the chorda tympani also carries parasympathetic fibres to the salivary glands of the oral cavity. To date, little has been reported about the effect of chorda tympani section upon salivary function.Setting:Tertiary care centre.Material and methods:We report a case series of three patients with bilateral chorda tympani lesions. Chorda tympani function was assessed using ‘taste strips’ and unstimulated sialometry. A careful history of oral symptoms was taken.Results:All patients showed transient or permanent bilateral ageusia of the anterior two-thirds of the tongue, and a decreased resting salivary flow rate. In addition, all patients suffered from transient or persistent, distressing xerostomia.Conclusion:Taste disorders may occur after middle-ear surgery but they are mostly transient, even when the chorda tympani nerves are sectioned bilaterally. In contrast, bilateral chorda tympani lesions may lead to severe, persistent and distressing xerostomia. Based on this neglected aspect of chorda tympani function, we emphasise the importance of preserving the chorda tympani whenever possible.

OBJECTIVE: To determine the frequency and clinical manifestations of patients with post-poliomyelitis syndrome (PPS) in a Brazilian division of neuromuscular disorders. METHODS: A total of 167 patients with prior history of paralytic poliomyelitis was investigated for PPS, based on international diagnostic criteria. Other variables analyzed were: gender, race, age at poliomyelitis infection, age at PPS onset, and PPS symptoms. RESULTS: One hundred and twenty-nine patients presented PPS, corresponding to 77.2% of the studied population. 62.8% were women and 37.2% were men. Mean age of patients with PPS at onset of PPS symptoms was 39.9±9.69 years. Their main clinical manifestations were: new weakness in the previously affected limbs (69%) and in the apparently not affected limbs (31%); joint pain (79.8%); fatigue (77.5%); muscle pain (76%); and cold intolerance (69.8%). CONCLUSIONS: Most patients of our sample presented PPS. In Brazil, PPS frequency and clinical features are quite similar to those of other countries.

Background: Tramadol use has been increasing in the adult and pediatric population. Practitioners must be alert because Tramadol misuse can lead to severe intoxication in which respiratory failure and seizures are frequent. Overdoses can lead to death. We report 47 pediatric cases with history of accidental tramadol exposure in children.Methods: An observational, retrospective, single center case -series of children with a history of accidental tramadol exposure in children admitted in pediatric intensive care unit of tertiary care center, Niloufer Hospital (Osmania Medical College) Hyderabad, Telangana India.Results: Of 47 children, 22 (47%) are male and 25 (53%) were female. At presentation 11 (23%) had loss of consciousness, 14 (29%) seizures, 17 (36%) hypotonia was noted. Pupils were miotic in 22 (47%) mydriatic in 2 (4.2%) normal in rest of children. Hemodynamic instability noted in 13 (27.6%). Serotonin syndrome (tachycardia, hyperthermia, hypertension, hyper reflex, clonus) was noted on 5 (10.6%) children. Respiratory depression was seen in 4 (8%) children who needed ventilatory support. Antidote Naloxone was given in 7 children. No adverse reaction was noted with Naloxone. All 47 children were successfully discharged.Conclusions: Overdoses can lead to death and practitioners must be alert because of the increasing use of tramadol in the adult and pediatric population. The handling of the tramadol should be explained to parents and general population and naloxone could be efficient when opioid toxicity signs are present.

Purpose Technological advancements and the ever-increasing use of computed tomography (CT) have greatly increased the detection of incidental findings, including tiny pulmonary nodules. The management of many “incidentalomas” is significantly influenced by a patient's history of cancer. The study aim is to determine if CT requisitions include prior history of malignancy. Methods Requisitions for chest CTs performed at our adult tertiary care hospital during April 2012 were compared to a cancer history questionnaire, administered to patients at the time of CT scan. Patients were excluded from the study if the patient questionnaire was incomplete or if the purpose of the CT was for cancer staging or cancer follow-up. Results A total of 569 CTs of the chest were performed. Of the 327 patients that met inclusion criteria, 79 reported a history of cancer. After excluding patients for whom a history of malignancy could not be confirmed through a chart review and excluding nonmelanoma skin cancer, dysplasia, and in situ neoplasm, 68 patients were identified as having a history of malignancy. We found 44% (95% confidence interval [0.32-0.57]) of the chest CT requisitions for these 68 patients did not include the patient's history of cancer. Of the malignancies that were identified by patient questionnaire but omitted from the clinical history provided on the requisitions, 47% were malignancies that commonly metastasize to the lung. Conclusions A significant number of requisitions failed to disclose a history of cancer. Without knowledge of prior malignancy, radiologists cannot comply with current guidelines regarding the reporting and management of incidental findings.

ABSTRACT Objectives: To study the cleft lip and cleft palate in the poverty stricken Sub-Himalayan Garhwal region of India, being a commonly seen congenital abnormality and scarcity of studies about the demography of cleft in this region. Design: A prospective cohort observational case series was performed on 4657 cleft patients at a Tertiary care Hospital in Dehradun, India, over a period of 5 years. Outcome measures: The authors investigated the differences between age and sex with cleft status and family history of clefts, birth order, religion, socioeconomic status, parent literacy, source of information for treatment, haematological investigations showing the status of infection and coagulation in such children and satisfaction after treatment. Results: Seventy-two percent parents of cleft lip patients were illiterate, and only 8% were graduates, the majority of patients were from the low socioeconomic class. The siblings of 1.1% of the cleft patients had similar deformity. Anemia was seen in 83.16% cases which was commonly microcytic hypochromic type and eosinophilia was seen in 25.50% of cases. In the coagulation profile, International Nationalized Ratio was found to be raised in 52.12%. Almost 95% of the families were fully satisfied by the treatment and results. Conclusion: This study will provide baseline information on the status of these less privileged cleft patients in this mountainous region for future reference to health workers.

Abstract Background Rhino-Orbital-Cerebral Mucormycosis (ROCM) is an important infectious disease encountered in huge number in this recent post-covid 19 era. An alteration in defence immune system during covid-19 illness, in the presence of uncontrolled hyperglycaemia has led to the new epidemic of ROCM especially in developing nations like India. Method This case series of thirteen patients illustrates the various clinical presentation, laboratorical parameters, imaging features and outcome of patients of ROCM admitted in a tertiary care hospital in Northern India. Result In our case series, a total of 13 newly diagnosed cases of Rhino-Orbital-Cerebral Mucormycosis were studied. History of covid-19 illness was observed in 7 cases (53.8%), use of steroid during Covid-19 illness was seen in 5 cases (38.5%), oxygen therapy was given in 4 cases (30.8%). Co-morbid state in the form of diabetes mellitus was present in 12 cases (92.3%) with mean duration 16.69 months with an important finding of 6 cases (46.2%) having new-onset diabetes; hypertension in present in 3 cases (23.1%). Magnetic resonance imaging of paranasal sinuses showed involvement of multiple sinuses in all the 13 cases(100%), including maxillary and ethmoidal sinuses, with frontal in 12 cases (92.3%), sphenoidal in 11 cases (84.6%), symmetric in 9 cases (69.2%), mastoiditis in 4 cases (30.8%), maxillary space involvement in 4 cases (30.8%), palatal involvement in 1 case (7.7%). Multi-speciality approach treatment was given in the liposomal amphotericin B therapy in all the patients along with thorough endo-nasal debridement done in all cases, transcutaneous retrobulbar amphotericin B in 6 cases (46.2%) with exenteration done in 7 patients (53.9%). At 3 months of follow-up, there was substantial clinical improvement in all the cases. Conclusion There should be definite emphasis on high suspicion of mucor clinically for early diagnosis and aggressive management at initial state of diagnosis for better outcome. The need for sustained proper glycemic control during covid 19 era along with judicious use of steroid and public awareness for early symptoms and manifestations of mucor can curb the magnitude of such potentially opportunistic epidemic to a substantial rate. The longer the infection remains undetected, the greater the devastation ROCM can impose, of which blindness is an important hazard.

Background: Gallbladder is rarely injured as it is embedded in the liver and well protected by ribcage. Gallbladder perforation is a rare complication of acute calculus cholecystitis. Spontaneous gallbladder perforation is even rarer.Case Series: We present our experience of 4 cases of spontaneous gallbladder perforation. The patients were mostly males (3:1) with age ranging from 42-64 years. All the patients presented with abdominal pain, distension, ileus and fever ranging from 2-5 days duration. There was no prior history of biliary colic. Examination revealed abdominal tenderness and ileus. Abdominal radiographs showed multiple air-fluid levels and no pneumoperitoneum. Sonography and CT scan of abdomen revealed pericholecystic fluid, intra-abdominal collection with no evidence of gallstones. Provisional diagnosis was peritonitis in 3 and acute pancreatitis in one case. Image guided abdominal paracentesis yielded bilious fluid. In view of lack of clinical improvement and aspiration of bilious content all the patients were subjected to laparotomy. Gallbladder perforation in fundus region without stones and intra-abdominal bile collection was noted in all the patients. Cholecystectomy with peritoneal lavage and abdominal drainage was performed in all cases. Postoperative course was uneventful except wound infection in 2 cases. Histopathology report revealed features of acute cholecystitis in 2 and acute on chronic cholecystitis in the remaining 2 patients.Conclusion: Diagnosis of spontaneous gallbladder perforation should be suspected in middle aged patients who present with acute abdomen but does not have classical signs of peritonitis and in whom paracentesis has yielded bilious fluid.

Abstract Background While Clostridium difficile gastrointestinal infection (CDI) is the most common hospital-acquired infectious disease, C. difficile bacteremia (CDB) is exceedingly rare and its risk factors, mortality rate, and modalities of treatment are not well defined. Methods We conducted a retrospective, IRB approved, chart review of adult patients with a diagnosis of CDB admitted to our institutions from 2011 through 2017. Variables catalogued included previous antibiotic and proton pump inhibitor (PPI) use, co-morbid conditions, prior history of CDI, diarrhea at the time of CDB, active malignancy, and gastrointestinal (GI) disruption (e.g., perforated viscous, GI bleeding, abdominal malignancy). Treatment courses and outcomes for CDB were also gleaned. Results Seven patients with CDB were identified, with ages ranging from 35 to 81 years (median 65 years). Six (85.7%) patients had evidence of GI disruption and three (42.9%) were noted to have active cancer. Three (42.9%) patients had previous CDI by testing and three (42.9%) had complaints of diarrhea at the time of diagnosis. Six (85.7%) patients had exposure to PPIs before CDB diagnosis, and five (71.4%) had prior antibiotic exposure in the past 30 days. Five (71.4%) patients had a polymicrobial bloodstream infection, with the majority of organisms being enteric in nature. In terms of CDB treatment, the majority of patients received intravenous (IV) metronidazole and/or IV vancomycin in addition to broad-spectrum antibiotics due to the polymicrobial nature of their infection. Three (42.9%) patients died during their hospitalization, only one who had polymicrobial bacteremia. Conclusion CDI is the most common cause of hospital acquired infection, although rarely causes bacteremia. Notable findings in our population included older age, concomitant malignancy, evidence of GI disruption, and prior exposure to PPIs and antibiotics. Antibiotics chosen to treat CDB were IV metronidazole and/or IV vancomycin, with other broad-spectrum antibiotics utilized due to polymicrobial bacteremia. CDB is associated with a high mortality rate and is commonly manifested as a polymicrobial bloodstream infection. This is one of the larger case series that adds to the scant literature characterizing patients diagnosed with CDB. Disclosures All authors: No reported disclosures.

OBJECTIVE The goals of this study were to retrospectively review high-resolution CTs (HRCTs) of pediatric postmeningitic cochlear implant recipients and to correlate results with surgical findings. METHODS HRCTs of 20 children (11 months to 12 years old) who underwent implantation with multichannel devices were reviewed. Results were correlated with the degree of ossification observed at surgery. RESULTS Ninety percent of subjects required drilling of ossified bone within the basal turn at surgery. HRCT of the cochleas suggested ossification within the basal turn in 45% (50% sensitivity). Ossification of the lateral semicircular canal on HRCT was present in 72% (77% sensitivity). Five of 6 cases without radiographic evidence of ossification had positive findings at surgery. CONCLUSION Ossification is a common occurrence in postmeningitic deaf children. Ossification of the lateral semicircular canal on HRCT is a more sensitive measure for predicting ossification than evidence of cochlear involvement. Absence of ossification on HRCT is no guarantee of cochlear patency at the time of implantation.
