RESUMO
Percutaneous tracheostomy (PT) is a commonly performed procedure in ICUs as a safe and cost-effective alternative to surgical tracheostomy (ST). Bronchoscopy is frequently used during PT for real-time confirmation of needle placement and tube positioning. We present a case of a 42-year-old female with a complex medical history who underwent PT and experienced acute airway loss due to endotracheal tube obstruction caused by accumulated secretions. To prevent such complications, vigilance regarding airway obstruction, cautious bronchoscope advancement, avoiding endotracheal tube puncture, and readiness to abort the procedure and replace the tube are crucial.
RESUMO
Purpose: To examine the association of cigarette use and smoking-related health conditions by race/ethnicity among diverse and low-income patients at a federally qualified health center (FQHC). Methods: Demographics, smoking status, health conditions, death, and health service use were extracted from electronic medical data for patients seen between September 1, 2018, and August 31, 2020 (n=51,670). Smoking categories included everyday/heavy smoker, someday/light smoker, former smoker, or never smoker. Results: Current and former smoking rates were 20.1% and 15.2%, respectively. Males, Black, White, non-partnered, older, and Medicaid/Medicare patients were more likely to smoke. Compared with never smokers, former and heavy smokers had higher odds for all health conditions except respiratory failure, and light smokers had higher odds of asthma, chronic obstructive pulmonary disease, emphysema, and peripheral vascular disease. All smoking categories had more emergency department visits and hospitalizations than never smokers. The associations between smoking status and health conditions differed by race/ethnicity. White patients who smoked had a greater increase in odds of stroke and other cardiovascular diseases compared with Hispanic and Black patients. Black patients who smoked had a greater increase in odds of emphysema and respiratory failure compared with Hispanic patients. Black and Hispanic patients who smoked had a greater increase in emergency care use compared with White patients. Conclusion: Smoking was associated with disease burden and emergency care and differed by race/ethnicity. Health Equity Implications: Resources to document smoking status and offer cessation services should be increased in FQHCs to promote health equity for lower income populations.
RESUMO
BACKGROUND: Non-invasive oxygen therapy (NIT) consists of high-flow nasal oxygen (HFNO) and continuous positive airway pressure (CPAP). NIT is routinely being used for the management of acute respiratory failure secondary to coronavirus disease-2019 (COVID-19) with variable outcomes. However, previously published studies show that NIT failure might delay endotracheal intubation and invasive mechanical ventilation and results in worse outcomes in patients with hypoxemic respiratory failure. Early prediction of failure of NIT, will help in early decision-making in initiating invasive mechanical ventilation. We retrospectively studied the predictors for NIT failure in patients with moderate to severe COVID-19. METHODS: Adult patients (>18 years) admitted to the intensive care unit (ICU) with moderate to severe COVID-19 ARDS and received NIT [HFNO and CPAP non-invasive ventilation (NIV)] were included in this study. Baseline clinical and laboratory data were collected retrospectively from the electronic hospital information system. NIT failure was defined as the need for invasive mechanical ventilation after the initiation of NIT in the ICU. Univariate and multivariate logistic regression analyses were used to find out the possible predictors of NIT failure. RESULTS: Out of 254 patients admitted to ICU, 127 patients were initiated NIT at admission to ICU. During the course of the ICU stay, 33 (26%) patients subsequently required invasive mechanical ventilation (NIT failure). Respiratory rate-oxygenation index (ROX index) of <2.97 at two hours and <3.63 at six hours of ICU admission predicted NIT failure in our cohort of patients with a high positive predictive value. CONCLUSION: Patient selection is crucial for successful NIT in COVID-19. Application of ROX index measured in the first six hours of ICU admission helps in the identification of patients at risk of NIT failure with moderate to severe COVID-19 ARDS.
RESUMO
Background and objectives Recent randomized controlled trials (RCTs) have indicated potential therapeutic benefits with high-dose dexamethasone (HDD) or tocilizumab (TCZ) plus standard care in moderate to severe coronavirus disease 2019 (COVID-19) with acute respiratory distress syndrome (ARDS). No study has compared these two against each other. We aimed to compare the efficacy and safety of HDD against TCZ in moderate to severe COVID-ARDS. Methods Patients admitted with moderate to severe COVID-19 ARDS with clinical worsening within 48 hours of standard care were randomly assigned to receive either HDD or TCZ plus standard care. The primary outcome was ventilator-free days (VFDs) at 28 days. The main secondary outcomes were 28-day all-cause mortality and the incidence of adverse events. Our initial plan was to perform an interim analysis of the first 42 patients. Results VFDs were significantly lower in the HDD arm (median difference: 28 days; 95% confidence interval (CI): 19.35-36.65; Cohen's d = 1.14;p < 0.001). We stopped the trial at the first interim analysis due to high 28-day mortality in the HDD arm (relative risk (RR) of death: 6.5; p = 0.007; NNT (harm) = 1.91). The incidence of secondary infections was also significantly high in the HDD arm (RR: 5.5; p = 0.015; NNT (harm) = 2.33). Conclusions In our study population, HDD was associated with a very high rate of mortality and adverse events. We would not recommend HDD to mitigate the cytokine storm in moderate to severe COVID-19 ARDS. TCZ appears to be a much better and safer alternative.
RESUMO
OBJECTIVE: To evaluate the analgesic effi cacy of dexamethasone (DXA) vs. dexmedetomidine (DXM) as an adjunct to ropivacaine in ultrasound-guided interscalene block (USG-ISB) for arthroscopic shoulder surgery. METHODS: In this randomized double-blinded controlled trial, 60 American Society of Anesthesiologists grade 1-2 patients, 18-65 years, scheduled for arthroscopic shoulder surgery were randomly allocated to either group 1 (USG-ISB given with 0.5% ropivacaine 20 mL with 2 mL of saline containing DXM 0.5 mcg/kg) or group 2 (same protocol but DXA 8 mg instead of DXM). ISB was performed with in-plane technique under USG. Following surgery under general anesthesia, the patients received intravenous patient-controlled analgesia with fentanyl. Data were collected at 2-hourly intervals up to 24 hours after USG-ISB. The primary outcome was the duration of analgesia. Secondary outcomes consisted of pain ratings, total cumulative postoperative fentanyl consumption, patient satisfaction, and adverse effects. RESULTS: The groups were comparable regarding baseline demographic and clinical characteristics including onset of sensory and motor block. The duration of postoperative analgesia for group 2 was signifi cantly longer than for group 1 (22.40 ± 2.16 h vs. 19.30 ± 3.80 h; p < 0.001). Group 2 also required less total median number of boluses than group 1 (0 vs. 3; p < 0.001), less total fentanyl consumption (10.00 mcg ± 24.20 vs. 40.33 mcg ± 38.70; p < 0.001), less pain scores, and greater satisfaction (99.30 ± 2.53 vs. 93.30 ± 11.50; p=0.007). Adverse effects were few and comparable in both groups. CONCLUSION: Greater postoperative analgesia and opioid sparing effect was observed in patients receiving 8 mg DXA as adjunct for USG-ISB.

BACKGROUND: Phenol and alcohol have been used to ablate nerves to treat pain but are not specific for nerves and can damage surrounding soft tissue. Lidocaine at concentrations > 8% injected intrathecal in the animal model has been shown to be neurotoxic. Tests the hypothesis that 10% lidocaine is neurolytic after a peri-neural blockade in an ex vivo experiment on the canine sciatic nerve. METHODS: Under ultrasound, one canine sciatic nerve was injected peri-neurally with 10 cc saline and another with 10 cc of 10% lidocaine. After 20 minutes, the sciatic nerve was dissected with gross inspection. A 3 cm segment was excised and preserved in 10% buffered formalin fixative solution. Both samples underwent progressive dehydration and infusion of paraffin after which they were placed on paraffin blocks. The sections were cut at 4 µm and stained with hemoxylin and eosin. Microscopic review was performed by a pathologist from Henry Ford Hospital who was blinded to which experimental group each sample was in. RESULTS: The lidocaine injected nerve demonstrated loss of gross architecture on visual inspection while the saline injected nerve did not. No gross changes were seen in the surrounding soft tissue seen in either group. The lidocaine injected sample showed basophilic degeneration with marked cytoplasmic vacuolation in the nerve fibers with separation of individual fibers and endoneurial edema. The saline injected sample showed normal neural tissue. CONCLUSIONS: Ten percent lidocaine causes rapid neurolytic changes with ultrasound guided peri-neural injection. The study was limited by only a single nerve being tested with acute exposure.
RESUMO
BACKGROUND: Newborn screening comprises a paramount public health program seeking timely detection, diagnosis, and intervention for genetic disorders that may otherwise produce serious clinical consequences. Today newborn screening is part of the health care system of developed countries, whereas in India, newborn screening is still in the toddler stage. METHOD: We searched PubMed with the keywords newborn screening for metabolic disorders, newborn screening in India, and congenital disorder in neonates, and selected publications that seem appropriate. RESULTS: In India, in spite of the high birth rate and high frequency of metabolic disorders, newborn screening programs are not part of the health care system. At Union Territory, Chandigarh in 2007, newborn screening was initiated and is currently ongoing for three disorders, that is, congenital hypothyroidism, congenital adrenal hyperplasia, and glucose-6-phosphate dehydrogenase (G6PD) deficiency. Prevalence of these disorders is found to be 1:1400 for congenital hypothyroidism, 1:6334 for congenital adrenal hyperplasia, and 1:80 for G6PD deficiency. CONCLUSION: Mandatory newborn screening for congenital hypothyroidism should be implemented in India, and other disorders can be added in the screening panel on the basis of region-wise prevalence. The objective of this review is to provide insight toward present scenario of newborn screening in India along with recommendations to combat the hurdles in the pathway of mandatory newborn screening.

ETHNOPHARMACOLOGICAL RELEVANCE: Corchorus depressus Linn. has been used as an aphrodisiac in traditional Indian medicine to treat male sexual dysfunction and impotency. AIM OF THE STUDY: The petroleum ether, chloroform, ethyl acetate, n-butanol and aqueous fractions of 95% methanol extract of Corchorus depressus were screened initially for their in vitro aphrodisiac activity on rabbit corpus cavernosum smooth muscle. The chloroform fraction (CDC) was found to be the most active and therefore investigated further on general mating behavior, libido and potency of normal male Wistar albino rats in comparison with the standard drug, Sildenafil citrate. MATERIALS AND METHODS: Animals were divided into the following groups: Control, SC CDC 100, CDC 200, and CDC 400, who received saline, Sildenafil citrate or the chloroform fraction of Corchorus depressus at doses of 100, 200 or 400mg/kg b.wt., respectively. The route of administration for all the groups was oral dosing, which was once in a day for 45 days. To analyze the mating behavior, female rats with estrus phase were used. RESULTS: The chloroform fraction of methanolic extract of Corchorus depressus significantly reduced ML, IL, PEI and III. There was a significant increase in the MF, IF and EL and serum testosterone levels throughout the study period. The potency test significantly increased erections, quick flips, long flips and total reflex. In vitro aphrodisiac activity was significantly higher in chloroform fraction at a concentration of 25.0mg/ml, which induced 71.4% relaxation. The combined results of the above mentioned models indicate that the chloroform fraction of Corchorus depressus produces a significant increase in sexual activity as exhibited by 25mg/ml in vitro and 400mg/kg in vivo. In comparison with the control, all the drug-treated groups have shown drug-induced effects for a few parameters. CONCLUSIONS: In vitro and in vivo studies provide valuable experimental evidence that the chloroform fraction of methanolic extract of Corchorus depressus possesses aphrodisiac property. This study further substantiates the ethnopharmacological claims of Corchorus depressus as a sexual stimulating agent and offers a significant potential for studying the effect on male sexual response and its dysfunctions.

OBJECTIVE: Down syndrome (DS) has major resource implications especially in developing countries being third most important cause of mental handicap. Maternal serum screening for chromosomal aneuploidies and neural tube defects (NTDs) is practiced worldwide in many countries and has been integrated into mainstream health care, while it is gradually gaining momentum in Asian countries. METHODS: This prospective cohort study was carried out in pregnant women undergoing triple screening test between January 2007 and December 2010 after informed consent. Biomarkers alpha-fetoprotein, human-chorionic-gonadotropin and unconjugated-estriol were tested, and risk of pregnancy being affected with DS, Edward's syndrome or NTDs were calculated. Screen-positive patients were referred for detailed ultrasonography and confirmatory amniocentesis. Follow-up record was maintained until delivery. RESULTS: Of 7400 pregnant women enrolled, 419(5.7%) were screen-positive, including 339 positive for DS, two for trisomy 18, and 62 for NTDs. Total eight cases of DS were eventually diagnosed in the population (prevalence of DS = 1 : 925), seven of which were detected in utero following diagnostic evaluation for positive serum screen (DR of DS screen = 87.5%). Total five cases of NTD were observed, yielding NTD prevalence of 0.67/1000. CONCLUSIONS: Triple screening in the second trimester is reasonably effective for the detection of major chromosomal defects and NTDs, and can be implemented successfully also in India.

The test of the inner tube integrity is an important checklist prior to the safe use of Bain's breathing system. This is because the major concern with the use of Bain's circuit is the potential malfunctioning of the circuit due to avulsion of the inner fresh gas delivery tube at the machine end which will turn the outer tube into dead space, a hazard recognized by Hannallah. Pethick test although widely used may not be foolproof to detect leaks in the inner tube. Ghani suggested the use of a plunger to perform the inner tube occlusion. Partially or completely occluded outer tube may produce a false positive result. Using very high flows or prolonged occlusion may cause damage to anesthetic machine due to high pressure.

A 66-year-old man reported a slowly growing tumor on the lateral edge of his left upper eyelid. This lesion was hard but movable on palpation. A neoplasm of the lacrimal gland was suspected. CT showed a highly calcified lesion at the left upper eyelid. Resection of the tumor was performed, which was located just behind the orbital septum and in front of the lacrimal gland. Anatomopathologic investigation of the excised specimen with immunohistochemistry revealed a benign meningioma of a meningotheliomatous type, containing multiple bone elements. An ectopic orbital meningioma is rare, and this is the first case of a unique lateral localization of this lesion. Therefore, it should be included in the differential diagnosis of a lacrimal gland tumor.
