Clinical Profile, Complications and Trends of Ocular Anaesthesia in a Multi-tier Ophthalmology Network in India: An Eight-Year Experience.

INTRODUCTION: To describe the clinical profile, complications and trends of ocular anaesthesia in a multi-tier ophthalmology network in India. METHODS: This retrospective hospital-based study included 417,622 patients presenting between January 2013 and December 2020. Patients who were administered either topical, local or general anaesthesia for ocular surgery in at least one eye were included as cases. The data were collected using an electronic medical record system. RESULTS: Among the 417,622 patients, local anaesthesia was administered to 280,638, (67.2%) patients and was the most commonly administered type followed by topical anaesthesia in 84,117 (20.14%) patients. The most common complication encountered in administering local anaesthesia was retrobulbar haemorrhage in 103 (0.037%) patients followed by lid haematoma in 49 (0.017%) patients. Tooth damage occurred in 40 (0.076%) patients followed by delayed recovery in 30 (0.057%) patients during general anaesthesia. The trend of local anaesthesia decreased (83.48% vs 53.36%), whereas the trend of topical anaesthesia increased (8.61% vs 32.42%) over the study period. CONCLUSION: There is a notable trend towards the adoption of less invasive anaesthetic methods, particularly in common surgeries such as cataract, intravitreal injection, and vitreoretinal surgery. However, despite this trend, a significant proportion of oculoplastic/orbital surgeries, trauma, and strabismus surgeries continue to be performed under general anaesthesia. These observations underscore the ongoing evolution of ocular anaesthesia practices, reflecting advancements in surgical techniques and patient preferences.

Fever at Time of Leukemia Diagnosis in Children: Predictor of Bloodstream Infection or Catheter Removal?

PURPOSE: To assess the incidence of fever at diagnosis in children with leukemia and determine if fever at diagnosis is a predictor of bloodstream infection (BSI) or central venous access device (CVAD) removal for infection either within the first 30 days or between 30 and 90 days after CVAD insertion. MATERIALS AND METHODS: One hundred fifty-one patients with acute leukemia (July 1, 2018, to December 31, 2020) who underwent a CVAD insertion within 2 weeks of diagnosis were included. Patient data included demographic characteristics, fever at diagnosis, CVAD type, antibiotics before and/or on the day of CVAD insertion, BSI incidence, BSI rates per 1,000 catheter days, and need for catheter removal after CVAD insertion within 30 days and between 30 and 90 days. RESULTS: Patients with fever at diagnosis had a significantly higher incidence of BSI within the first 30 days after CVAD insertion (17/23) than that among patients without fever (6/23) (P = .046) at diagnosis. No statistically significant difference was observed in the incidence of BSI between 30 and 90 days after CVAD insertion between patients with fever (5/11) and those without fever at diagnosis (6/11) (P = .519). Fever at diagnosis was not a predictor of CVAD removal within 30 days (9 patients required CVAD removal; 7/9 had fever and 2/9 had no fever) (P = .181) or between 30 and 90 days (4 patients required CVAD removal; 1/4 had fever and 3/4 had no fever at diagnosis) (P = .343) after insertion. CONCLUSIONS: Fever at diagnosis in patients with leukemia is not a predictor of CVAD removal for infection.

Fibrolipomatous hamartoma of the median nerve in a child with carpal tunnel syndrome: imaging findings and literature review.

Fibrolipomatous hamartoma of the median nerve is an uncommon benign tumour of the childhood, which usually manifests in adolescents or adulthood with signs of compressive neuropathy at wrist. Symptomatic tumour is unusual in children below 5 years age and can be underdiagnosed. Magnetic resonance imaging provides pathognomonic features for the diagnosis, obviating the need for biopsy. Although standard ultrasonography is frequently the first-line imaging approach in the evaluation of soft-tissue masses, sonographic findings of this lesion are less frequently reported and have to be kept in mind by radiologist. We report the unusual case of carpal tunnel syndrome secondary to fibrolipomatous hamartoma of the median nerve in a 4-year-old child successfully treated with surgical carpal tunnel release.

Pediatric liver cirrhosis interventional procedures: from biopsy to transjugular intrahepatic portosystemic shunt.

Cirrhosis is a complex diffuse process whereby the architecture of the liver is replaced by abnormal nodules because of the presence of fibrosis. Several pediatric diseases such as extrahepatic portal vein obstruction, biliary atresia, alpha-1-antitrypsin deficit and autoimmune hepatitis can lead to cirrhosis and portal hypertension in children. In this article the authors describe interventional radiology procedures that can facilitate the diagnosis and treatment of diseases associated with liver cirrhosis and portal hypertension in the pediatric population. These procedures include image-guided liver biopsy, mesenteric-intrahepatic left portal vein shunts, balloon-occluded retrograde transvenous obliteration, transjugular intrahepatic portosystemic shunts and splenic embolization.

Case report: Bilateral pleural effusion secondary to late migration of a tunneled central venous catheter in a patient affected by high risk neuroblastoma.

The insertion of long-term central venous catheters is a standard of care for children affected by malignancies, although it can be associated with life-threatening complications. The present paper reports an unusual mechanical complication related to the use of a long term tunneled central venous catheter in a pediatric oncologic patient. An 18 months old child, diagnosed with stage M high-risk retroperitoneal neuroblastoma, underwent ultrasound-guided placement of a 6 Fr bilumen long-term tunneled central venous catheter in the right internal jugular vein prior to the beginning of induction chemotherapy. The correct position of the distal tip of the catheter was confirmed by fluoroscopy. After 4 months of regular use of the device, the patient experienced neck swelling during high-dose chemotherapy infusion. A chest x-ray showed a dislocated catheter and bilateral pleural effusion. CT scan demonstrated the tip of the catheter rupturing the medial wall of the right jugular vein and entering the mediastinum; furthermore, pneumomediastinum, subcutaneous neck emphysema and bilateral pleural effusion were noticed and a thrombus was evident in the right jugular vein at the insertion in the brachiocephalic vein. The patient was then transferred to the Intensive Care Unit and bilateral thoracostomy tubes were placed urgently (500 mL of clear fluid were evacuated from pleural spaces). The dislocated catheter was removed electively on the following day under fluoroscopy. Despite ultrasound-guided placement and long-term uneventful use of the catheter, life-threatening central venous catheter-related mechanical complications can occur; the current case report emphasizes the importance of careful monitoring of patients with central venous catheters in order to quickly diagnose and treat potentially lethal complications.

Color Doppler Evaluation of Arterial Resistive Index in Infantile Hemangioma: A Useful Parameter to Monitor the Response to Oral Propranolol?

Infantile hemangioma (IH) is the most common benign vascular tumor in childhood. In more than 85% of all cases, IHs undergo spontaneous involution, but nearly 10-12% of IHs develop complications and require immediate therapy. Oral propranolol is currently the first-line treatment for IHs. Color Doppler ultrasound is the gold standard in the diagnosis of deep IH, and it is used to evaluate the morphological change and the modification of vascularization that occur during its evolution and treatment. To date, only few data in the literature described the changes of intralesional arterial resistive index (RI) during treatment with propranolol; particularly, some authors have shown an increase of intralesional arterial RI in IHs with clinical regression during treatment with propranolol. The objective of this paper is to evaluate the changes of RI of the intralesional arteries of the IHs during the treatment with oral propranolol. We retrospectively analyzed a total of 64 IHs in 60 patients treated with oral propranolol with a good clinical response. Gray-scale ultrasonography and color Doppler imaging were performed before and during the therapy. The intralesional RIs were measured before and during the treatment. For each lesion, we recorded the RI values, and then we calculated the mean RI value for any single lesion. We compared the mean RI value observed at the baseline with the mean RI value of the last detectable sampling at color Doppler. We also compared between them the mean RI values observed during intermediate ultrasound. The RI values were compared in 44 lesions, with at least two significant samplings of RI. In the 44 lesions compared, we did not find statistically significant variations in the mean RI values between the baseline control and the values recorded at the last post-treatment control. The time trend of mean RI values of the intermediate color Doppler analysis performed between the first pre-treatment control and the last measurable control did not show any statistically significant variation in the trend of mean RI values. Contrarily to what has been described by some authors, in our experience, we have not observed an increase of RI in IHs treated with oral propranolol.

Single-Stage Revision With Fluconazole Monotherapy in Fungal Prosthetic Knee Joint Infections.

Fungal prosthetic joint infection is rare, and two-stage revision is usually advocated. We present our experience with 2 cases of fungal prosthetic knee joint infection presenting 25 months and 3 years after index surgery. Both patients were managed with single-stage revision arthroplasty and fluconazole monotherapy. They remain asymptomatic with good knee society score after 2 years of follow-up. Preoperative workup of all aseptic loosening cases should include extended culture for fungal elements. Single-stage revision with antifungal therapy for 3 months gives good results in nonimmunocompromised patients with good soft-tissue envelope.

Imaging in Vaping-associated Lung Injury: Beyond the Haze.

E-cigarette or vaping, product associated lung injury is a rampant public health issue with a total of 2807 reported hospitalized patients in the United States as of February 18, 2020. Limited data, non-specific symptoms, non-responsiveness to antibiotics, and the lack of a specific biomarker, make it a diagnosis of exclusion. Overlap of clinical and imaging findings with other ongoing respiratory illness (MERS, SARS and COVID-19) poses a challenge in accurate diagnosis. We compiled 3 cases of patients hospitalized with confirmed vaping-associated lung injury and analyzed their imaging patterns, which revealed bilateral consolidation, ground-glass opacities and pleural effusions. We also reviewed the available literature on pathophysiology, imaging findings of EVALI and other respiratory illness.

A Model of Care Optimized for Marginalized Remote Population Unravels Migration Pattern in India.

BACKGROUND AND AIMS: Access to basic health needs remains a challenge for most of world's population. In this study, we developed a care model for preventive and disease-specific health care for an extremely remote and marginalized population in Arunachal Pradesh, the northeasternmost state of India. APPROACH AND RESULTS: We performed patient screenings, performed interviews, and obtained blood samples in remote villages of Arunachal Pradesh through a tablet-based data collection application, which was later synced to a cloud database for storage. Positive cases of hepatitis B virus (HBV) were confirmed and genotyped in our central laboratory. The blood tests performed included liver function tests, HBV serologies, and HBV genotyping. HBV vaccination was provided as appropriate. A total of 11,818 participants were interviewed, 11,572 samples collected, and 5,176 participants vaccinated from the 5 westernmost districts in Arunachal Pradesh. The overall hepatitis B surface antigen (HBsAg) prevalence was found to be 3.6% (n = 419). In total, 34.6% were hepatitis B e antigen positive (n = 145) and 25.5% had HBV DNA levels greater than 20,000 IU/mL (n = 107). Genotypic analysis showed that many patients were infected with HBV C/D recombinants. Certain tribes showed high seroprevalence, with rates of 9.8% and 6.3% in the Miji and Nishi tribes, respectively. The prevalence of HBsAg in individuals who reported medical injections was 3.5%, lower than the overall prevalence of HBV. CONCLUSIONS: Our unique, simplistic model of care was able to link a highly resource-limited population to screening, preventive vaccination, follow-up therapeutic care, and molecular epidemiology to define the migratory nature of the population and disease using an electronic platform. This model of care can be applied to other similar settings globally.

Prognostic value of soluble ST2 biomarker in heart failure patients with reduced ejection fraction - A multicenter study.

OBJECTIVE: To study the prognostic value of soluble Suppression of Tumorigenicity-2 (sST2) in heart failure patients with reduced ejection fraction (HFrEF). METHODS: In this prospective, observational, multicenter study, patients with heart failure (HF) and left ventricular ejection fraction (LVEF) <50% were included. Clinical evaluation and serum levels of sST2 were estimated at five time points during follow up. Study endpoint was the relationship of baseline and serial sST2 concentration in the blood to the composite endpoints of cardiac death and re-hospitalization for worsening of HF during one year follow up period. RESULTS: A total of 141 patients were enrolled. The mean age was 60±10.4years. At baseline evaluation, 49.6% patients were in New York Heart Association (NYHA) class III and 36.2% in class IV. Adverse events were observed in 57 patients (40.4%); 25 (17.7%) were re-hospitalized due to worsening of HF and 32 (22.7%) died due to cardiac causes. The median value of baseline sST2 was 46.36ng/ml (IQR 31.30-78.38). sST2 concentration at baseline was significantly higher among patients with adverse events in comparison to patients without adverse events (p=<0.001). Receiver operating characteristic curve (ROC) for baseline sST2 concentration identified 49ng/ml as optimal cut-off value to predict cardiac death and re-hospitalization, with a sensitivity and specificity of 72% and 75%, respectively. CONCLUSION: In patients with HFrEF, sST2 concentration at baseline as well as on serial testing was significantly correlated with cardiac death and re-hospitalization for worsening of HF.

Role of endovascular embolization in treatment of acute bleeding complications in haemophilia patients.

OBJECTIVE:: Bleeding complications either spontaneously or post-operatively are very common in patients with haemophilia. Sometimes these bleeding complications remain unresponsive despite being on high dose of clotting factor replacement. The aim was to assess the role of endovascular embolization in patients with haemophilia in (a) treating haemorrhagic complications due to local causes refractory to clotting factors substitution and (b) reducing intraoperative blood loss in elective pseudotumour surgery. METHODS:: 10 patients seen between January 2000 and April 2015 with severe haemophilia A or B who had unexplained profuse persistent bleeding or required large pseudotumour excision and were taken up for digital subtraction angiography and embolization were included in the study. Data of all these patients were reviewed using the computerized hospital information system and picture archiving and communication system. Details including indications for the procedure, patient preparation for the procedure, imaging findings, details of angiography with intervention, if any, and outcome as well as follow-up data were analyzed. RESULTS:: In 6 of these 10 cases, bleeding was spontaneous, in 2 cases due to trivial fall and in 2 cases due to post-operative bleeding. Angiography in these patients revealed vascular blush, abnormal hypervascularity or active extravasation. In all 10 patients, an embolization procedure was performed, with bleeding controlled in 8 patients. There were no procedure-related complications during the procedure, post-procedure bleeding or haematoma at the site of arterial access. One patient had recurrence of bleeding for whom surgical exploration was required, and one patient had significant bleeding intraoperatively which was controlled with high-dose clotting factors, blood transfusion and fresh frozen plasma intraoperatively. CONCLUSION:: Endovascular embolization is a safe, effective and cost-saving procedure in arresting bleeding in selected patients with severe haemophilia who are unresponsive to adequate clotting factor replacement and where local vascular causes could be contributing to the bleeding. Pre-operative embolization is also a good procedure to reduce intraoperative blood loss in patients with large pseudotumours. ADVANCES IN KNOWLEDGE:: Angiography and embolization in patients with haemophilia is technically challenging and should be performed by highly skilled interventional radiologists, which limits its wider use and familiarity among multidisciplinary teams managing haemophilia. By bringing the knowledge of this effective treatment to the specialist groups who care for patients with haemophilia, its wider application may be possible which can save life and/or reduce morbidity.

A pulmonary metastasis of a cystosarcoma phyllodes of the breast detected by 18F-FDG PET/CT.

We describe a pulmonary metastasis of a cystosarcoma phyllodes of the breast (CPB) detected by F-FDG PET/CT. A 65-year-old female patient previously operated on for a cystosarcoma phyllodes of the left breast underwent F-FDG PET/CT for restaging. F-FDG PET/CT showed an area of increased F-FDG uptake corresponding to a 2-cm right pulmonary nodule. Histology suggested the presence of a pulmonary metastasis of CPB.
