RESUMEN

SETTING: Biratnagar Eye Hospital, Biratnagar, Nepal, which offers ear surgery for chronic suppurative otitis media (CSOM). OBJECTIVE: In patients with CSOM awaiting surgery, to determine the 1) sociodemographic characteristics 2) bacterial isolates and their antibiotic resistance patterns and 3) characteristics of those refused surgery, including antibiotic resistance. DESIGN: A cohort study using hospital data, January 2018-January 2020. RESULTS: Of 117 patients with CSOM and awaiting surgery, 64% were in the 18-35 years age group, and 79% were cross-border from India. Of 118 bacterial isolates, 80% had Pseudomonas aeruginosa and 16% had Staphylococcus aureus. All isolates showed multidrug resistance to nine of the 12 antibiotics tested. The lowest antibiotic resistance in P. aeruginosa was for vancomycin (29%) and moxifloxacin (36%), and for S. aureus, this was vancomycin (9%) and amikacin (17%). Fourteen (12%) patients underwent surgery: myringoplasty (n = 7, 50%), cortical mastoidectomy with tympanostomy (n = 4, 29%) and modified radical mastoidectomy (n = 3, 21%). Those infected with P. aeruginosa and with resistance to over six antibiotics were significantly more likely to be refused for surgery. CONCLUSION: Patients awaiting ear surgery were predominantly infected with multidrug-resistant P. aeruginosa and were consequently refused surgery. This study can help inform efforts for improving surgical uptake and introducing cross-border antimicrobial resistance surveillance.


LIEU: Hôpital ophtalmologique de Biratnagar, Népal, qui propose des interventions chirurgicales de l'oreille aux patients atteints d'otite moyenne chronique suppurée (CSOM). OBJECTIF: Déterminer 1) les caractéristiques sociodémographiques, 2) les isolats bactériens et leurs profils de résistance aux antibiotiques et 3) les caractéristiques des patients se voyant refuser la chirurgie (dont résistance aux antibiotiques) chez les patients atteints de CSOM en attente de chirurgie. MÉTHODE: Étude de cohorte réalisée à l'aide de données hospitalières, janvier 2018-janvier 2020. RÉSULTATS: Sur les 117 patients atteints de CSOM en attente de chirurgie, 64% appartenaient à la tranche d'âge des 18­35 ans et 79% étaient des patients transfrontaliers en provenance d'Inde. Sur 118 isolats bactériens, 80% étaient des isolats de Pseudomonas aeruginosa et 16% de Staphylococcus aureus. Tous les isolats ont montré une résistance à neuf des 12 antibiotiques testés. Les plus faibles résistances chez P. aeruginosa étaient celles à la vancomycine (29%) et à la moxifloxacine (36%). Pour S. aureus, il s'agissait de celles à la vancomycine (9%) et à l'amikacine (17%). Quatorze (12%) patients ont subi une intervention chirurgicale : myringoplastie (n = 7, 50%), mastoïdectomie corticale avec tympanotomie (n = 4, 29%) et mastoïdectomie radicale modifiée (n = 3, 21%). Les patients infectés par P. aeruginosa avec une résistance à plus de six antibiotiques étaient significativement plus susceptibles de se voir refuser la chirurgie. CONCLUSION: Les patients en attente de chirurgie de l'oreille étaient principalement infectés par un isolat multirésistant de P. aeruginosa, et se sont donc vu refuser la chirurgie. Cette étude peut permettre d'orienter les efforts visant à améliorer le taux de chirurgies réalisées et à mettre en place une surveillance transfrontalière des résistances antimicrobiennes.

RESUMEN

In this work, laser-induced breakdown spectroscopy (LIBS) has been used for the quantitative and qualitative analysis of the sage sample using the calibration-free LIBS (CF-LIBS) technique. The sage plasma is generated by focusing the second harmonics (532 nm) of a Q-switched Nd:YAG laser with a repetition rate of 10 Hz and pulse duration of 5 ns. The emission spectra are recorded using a LIBS 2000 detection system spectrometer consisting of five high-resolution spectrometers covering a wavelength range from 200 to 720 nm. The optical emission spectra of the sage sample reveal the spectral lines of Fe, Ca, Ti, Co, Mn, Ni, and Cr. The plasma temperature and electron number density of the neutral spectral lines of the pertinent elements have been deduced using the Boltzmann plot and Stark-broadening line profile method, with average values 8855±885K and 3.89×1016cm-3, respectively. The average values of the plasma parameters were used for the quantification of the detected elements in the sample. Based on the calibration-free method, the measured results demonstrate that Fe is the major constituent in the sample, having a percentage concentration of 48.1%, while the remaining elements are Ca, Ti, Co, Mn, Ni, and Cr, with percentage concentrations 0.7%, 5.3%, 8%, 11%, 12.3%, and 14.6%, respectively. This study demonstrates the feasibility of LIBS for the compositional analysis of major and trace elements present in the plant samples and its further applications in medicine.

RESUMEN

Provisions for post-trial access (PTA) of the experimental intervention are required before the start of a clinical trial. Although there has been ample attention for PTA in the context of preventive vaccine research, discussions on PTA barely include maternal vaccine trials in which mother-infant pairs are exposed to the intervention. In maternal vaccination trials, specific PTA arrangements are required because pregnancy is transient and PTA may apply to the next pregnancy or the child. In this article, we examine the application and adherence to PTA in the context of maternal vaccine trials. We focused on differences between publications before and after 2000 when international ethical guidance documents formalized PTA requirements. Randomized maternal vaccine trials were included after a systematic search for clinical trials in phases II and III with a maternal vaccine as intervention. We used PTA as defined at the time of publication in the World Medical Association's Declaration of Helsinki (DoH) or in the ethical guidelines of the Council for International Organizations of Medical Sciences (CIOMS). In addition, we investigated whether PTA was included in the trial design. Therefore, we contacted principal investigators (PI's) of the publications found in the review to fill out a questionnaire regarding provisions for PTA. Before and after 2000, no trial articles examined in the systematic review described PTA in their trial publication (0/7, 0% and 0/17, 0%, respectively). In addition, more than half of the PI's of the trials found were not familiar with PTA recommendations in international ethical guidelines. Most cases of PTA included making knowledge available by publishing the results of the trial. The revision of the DoH in 2002 and the CIOMS ethical guidelines in 2002 has not resulted in increased PTA provisions for maternal vaccination trials. PTA is a shared responsibility of various stakeholders including sponsors, Institutional Review Boards, regulators, political entities, and researchers. Inclusion of PTA provisions in trial protocols and publications on maternal vaccination trials is essential to increase transparency on the form and content of these provisions.

RESUMEN

There are two types of tumors found in the cardiac chamber. These are divided into primary intra-cardiac tumors and secondary intra-cardiac tumors. Primary intra cardiac tumors are rare and among them 29% are myxomas. Majority of them are found in the left atrium. Here, we report a case of a myxoma in the right atrium with hepatomegaly and Hepatitis B virus infection. The coexistence of all these conditions is very rare. A 52 years old patient presented with history of shortness of breath on exertion along with fever and generalized weakness for 6 months which aggravated lately for last 2 months. He was then taken for better medical care and hospitalization. On cardiac evaluation he had soft S1 and S2 over the tricuspid region on the right lower parasternal region. He had bilateral mild pitting pedal edema. On further examination, it was revealed that he had mild tender hepatomegaly with jaundice. His blood analysis for HBsAg was positive. Echocardiogram showed right atrial myxoma of 14.3cm² almost completely occupying the right atrium and even protruding into the Inferior Venacava however not fully obstructing it. The inferior vena cava size was mildly dilated (22mm). Abdominal ultrasound report showed hepatomegaly (17.6cm) with coarse hepatic parenchyma. In this report, we emphasize the rarity of myxoma in the Right Atrium, its difficult diagnosis because of the location and the atypical presentation in the echocardiograph.

RESUMEN

PurposeTo evaluate and compare the accuracy of modern intraocular lens (IOL) power calculation formulae in pediatric eyes and compare prediction error (PE) obtained with manufacturer's vs personalized lens constant.Patients and methodsAn observational case study was conducted in 117 eyes (117 patients) undergoing pediatric cataract surgery with IOL implantation. PE was calculated as predicted refraction minus actual postoperative refraction, and absolute PE as absolute difference independent of the sign, (APE)=predicted refraction minus actual postoperative refraction. This was done for each formula using manufacturer's and personalized lens constant. Further, PE and APE were evaluated according to axial length (AL).ResultsMean age of children was 2.97 years. About 66/117 eyes (56.4%) were below 2 years of age. Using Holladay 2, Holladay 1, Hoffer Q, and SRK/T formulae with manufacturer's lens constant, mean PE was 0.36, 0.41, 0.69, and 0.28 diopter (D), respectively. With personalized lens constant, it was 0.16, 0.15, 0.50, and -0.12 D, respectively. Difference in mean PE between the formulae was statistically significant (P<0.0001). SRK/T and Holladay 2 formulae had the least PE, both with manufacturer's and personalized constant. For eyes with AL<20 mm, SRK/T and Holladay 2 formulae gave the least PE. Personalizing the lens constant led to a decrease in mean PE in all formulae, except the Hoffer Q formula. However, personalizing the lens constant did not significantly improve the APE. At least 21% eyes had an APE of >2 D with all formulae, even with personalized lens constants.ConclusionIn pediatric eyes, SRK/T and the Holladay 2 formulae had the least PE. Personalizing the lens formula constant did reduce the PE significantly for all formulae except Hoffer Q. In extremely short eyes (AL<20 mm), SRK/T and Holladay 2 formulae gave the best PE.

RESUMEN

PURPOSE: Non-tuberculous mycobacteria (NTM) are important pathogens in lung transplant recipients. This study describes the spectrum of NTM respiratory tract infections and examines the association of NTM infections with lung transplant complications. METHODS: Data from 208 recipients transplanted from November 1990 to November 2005 were analyzed. Follow-up data were available to November 2010. Lung infection was defined by bronchoalveolar lavage, sputum, or blood cultures in the appropriate clinical setting. All identified NTM respiratory tract infections were tabulated. The cohort of patients with NTM lung infections (NTM+) were compared to the cohort without infection (NTM-). Univariate and multivariate analysis was performed to determine characteristics associated with NTM infection. Survival analyses for overall survival and development of bronchiolitis obliterans syndrome (BOS) were also performed. RESULTS: In total, 52 isolates of NTM lung infection were identified in 30 patients. The isolates included Mycobacterium abscessus (46%), Mycobacterium avium complex (MAC) (36%), Mycobacterium gordonae (9%), Mycobacterium chelonae (7%), and Mycobacterium fortuitum (2%), with multiple NTM isolates seen on 3 different occasions. The overall incidence was 14%, whereas cumulative incidences at 1, 3, and 5 years after lung transplantation were 11%, 15%, and 20%, respectively. Comparisons between the NTM+ and NTM- cohorts revealed that NTM+ patients were more likely to be African-American and have cytomegalovirus mismatch. Although no difference was seen in survival, the NTM+ cohort was more likely to develop BOS (80% vs. 58%, P = 0.02). NTM+ infection, however, was not independently associated with development of BOS by multivariate analysis. CONCLUSION: With nearly 20 years of follow-up, 14% of lung recipients develop NTM respiratory tract infections, with M. abscessus and MAC more commonly identified. M. gordonae was considered responsible for nearly 10% of NTM infections. Although survival of patients with NTM infections is similar, a striking difference in BOS rates is present in the NTM+ and NTM- groups.

RESUMEN

There is limited evidence and lack of consensus whether second-hand smoke (SHS) increases risk of tuberculosis (TB), which has substantial implications for unrestricted smoking indoors and TB control policies. We aimed to establish the association between SHS and the risk of acquiring and worsening of TB in non-smokers. We identified 428 articles in the initial search and 12 comparative epidemiological studies met our inclusion criteria. Exposure to SHS was found to have a higher risk of TB infection [risk ratio (RR) 1·19, 95% confidence interval (CI) 0·90-1·57] compared to non-exposure; however, this did not reach statistical significance. There was marked variability (I 2 = 74%, P = 0·0008) between studies' results, which could be explained by the differences in the diagnostic criteria used. Exposure to SHS was found to be statistically significantly associated (RR 1·59, 95% CI 1·11-2·27) with the risk of TB disease. There was significant heterogeneity (I 2 = 77%, P = 0·0006) between studies' results, which was sourced to the internal characteristics of the studies rather than combining different study designs. We did not find any studies for SHS and TB treatment-related outcomes. Thus, we conclude that SHS exposure may increase the risk of acquiring TB infection and progression to TB disease; however, the evidence remains scanty and weak.

RESUMEN

SUMMARY In general, tuberculosis (TB) is more common in men than women. However, for reasons currently not understood, women are 1.5-2 times more likely to report TB compared to men in Pashtun region (Afghanistan, adjacent provinces Pakistan and Iran). We explored whether or not gender disparity in TB notifications in the Pashtun region of Pakistan can be explained by Pashtun ethnicity. Using an ecological linear regression design, we estimated the effect of Pashtun ethnicity on female-to-male ratio (FMR) in TB notifications after adjusting for other determinants of women's health, in Pakistan. Districts with a high proportion of women of Pashtun ethnicity had a 44% (95% confidence interval 27-61) increase in FMR of notified TB cases compared to those with low proportions, after controlling for confounders. Genetic predisposition and distinct socio-cultural determinants could be possible causative factors. However, these hypotheses need further evaluation through rigorous longitudinal studies.

RESUMEN

Rhabdomyolysis is a syndrome characterized by injury to skeletal muscle fibers with disruption and release of toxic metabolites into circulation. It is characterized by triad of muscle weakness, myalgia and dark urine and is associated with increased creatine kinase and lactate dehydrogenase. A severely malnourished 10 year old girl with severe diabetic ketoacidosis as hemr initial presentation of type 1 diabetes mellitus developed rhabdomyolysis (CK- 12,000 U/L) with non-oliguric renal failure during her initial course of hospital stay. The possible cause of her RM was attributed to severe hypophosphatemia (minimum serum phosphate, 0.8 mg/dL). Management of diabetic ketoacidosis phosphate supplementation and urinary alkalinization with diuresis improved her clinical course. She was discharged on Day 9 with Insulin. We recommend frequent monitoring of serum phosphate during early period of DKA, particularly in malnourished children, and its normalization in case of severe hypophosphatemia.

RESUMEN

Fungal infections are common after lung transplantation. However, disseminated fusariosis is rare and we report the first case of airway complications associated with this infectious process. A 77-year-old Caucasian woman, who was status post left single-lung transplant for emphysema, presented to clinic 8 months after lung transplantation with pleurisy, shortness of breath, and declining lung function. Bronchoscopy showed narrowing of the left anastomotic site with dynamic compression during exhalation. An AERO stent was deployed successfully, but 3 weeks later, her symptoms recurred. Bronchoscopy showed total stent occlusion with thick tenacious mucus. Fusarium solani was isolated from cultures, and a new 1.5 cm skin nodule was found on the anteromedial midportion of the patient's left lower leg. Voriconazole and anidulafungin were started. No evidence of mucus accumulation was seen during a follow-up bronchoscopy. It is likely that Fusarium infection contributed to the initial anastomotic complication as well as to obstruction of the stent. Furthermore, the stent may have contributed to establishment and development of disseminated fusariosis. With antifungal therapy, stent patency was maintained and the patient improved clinically.

RESUMEN

CONTEXT: Donepezil is a centrally-acting, reversible acetylcholinesterase inhibitor that is used in the treatment of Alzheimer disease. Altered mental status, nausea, vomiting, and bradycardia have been reported in therapeutic and supratherapeutic ingestions of donepezil, though pediatric exposures have not been well-described. We report a case of prolonged altered mental status and recurrent bradycardia in a child with a single-pill ingestion of donepezil. CASE DETAILS: A 14-month-old boy was brought to the Emergency Department 3 hours after ingesting one of his grandfather's donepezil tablets (10 mg). Upon arrival, he was somnolent and drooling, with multiple episodes of vomiting and diarrhea. Pupils were normal. Initial vitals: temperature, 36.8°C; blood pressure, 103/56 mmHg; heart rate, 140/min; respiratory rate, 36/min; oxygen saturation, 97%. His drooling, vomiting, and diarrhea resolved, but he remained intermittently agitated. Over the course of the following four days, he had intermittent, episodes of asymptomatic bradycardia to a low of 55/min, primarily when sleeping. A transient episode of junctional rhythm was observed. Serum donepezil level 97 hours post-ingestion was 10 ng/ml. He did not require atropine treatment, and was discharged in stable condition on hospital day 5. DISCUSSION: Donepezil has a prolonged elimination of half-life in adults of approximately 70 hours. Despite its relative specificity for central AChEs, peripheral cholinergic symptoms have been described. We report a case of a symptomatic ingestion of donepezil in a child. CONCLUSIONS: Even after a single-tablet ingestion, donepezil may cause prolonged altered mental status and bradycardia in young children.

RESUMEN

BACKGROUND: Sexual dysfunction due to antipsychotics is a significant problem encountered with first-generation antipsychotics. Even the second-generation antipsychotics like risperidone are not free of sexual dysfunction due to its D2 blocking properties leading to hyperprolactinaemia. Newer antipsychotic aripiprazole, partial dopamine agonist, with neutral effect on prolactin level or even decreasing it, is associated with avoidance of sexual dysfunction. OBJECTIVES: To assess the effect of risperidone and aripiprazole on sexual function of schizophrenic patients. METHODS: This was an open-label, cross-sectional, observational study conducted at College of Medical Sciences, Bharatpur. Schizophrenic patients attending OPD and inpatient, taking risperidone or aripiprazole for at least two months were included in this study. Forty one patients, without chronic medical illness and sexual dysfunction before starting drugs, with informed consent were studied during Jan 2012 and Aug 2012. RESULTS: Changes in sexual activity was found in 11(55%) of those taking risperidone while, only 3(14.3%) had any kind of sexual difficulty. This was statistically significant (p=0.006). Majority, 92.7% of the patients did not report about changes in sexual activity spontaneously. CONCLUSION: Sexual dysfunction was statistically significantly higher in those taking risperidone. Prevalence of sexual dysfunction was low with aripiprazole. Except those having poor sexual functions due to the drugs, the majority had to be specifically inquired about the effects of drug on sex life.

RESUMEN

The Declaration of Helsinki and the Council of the International Organization of Medical Sciences provide guidance on standards of care and prevention in clinical trials. In the current and increasingly challenging research environment, the ethical status of a trial design depends not only on protection of participants, but also on social value, feasibility, and scientific validity. Using the example of a study assessing efficacy of a vaccine to prevent human papilloma virus in HIV-1 infected adolescent girls in low resource countries without access to the vaccine, we compare several trial designs which rank lower on some criteria and higher on others, giving rise to difficult trade-offs. This case demonstrates the need for developing more nuanced guidance documents to help researchers balance these often conflicting criteria.

RESUMEN

Lung nodules after lung transplantation most often represent infection or post-transplant lymphoproliferative disorder in the allograft. Conversely, native lung nodules in single lung transplant recipients are more likely to be bronchogenic carcinoma. We present a patient who developed native lung cavitary nodules. Although malignancy was anticipated, evaluation revealed probable Phaeoacremonium parasiticum infection. Phaeoacremonium parasiticum is a dematiaceous fungus first described as a cause of soft tissue infection in a renal transplant patient. Lung nodules have not been previously described and this is the first case, to our knowledge, of P. parasiticum identified after lung transplantation.

RESUMEN

Xpert(®) MTB/RIF testing was offered to consecutive patients with presumptive tuberculosis (TB) attending two hospitals in Pakistan during April-May 2012, in addition to routine diagnostic protocol (smear microscopy, chest radiography and clinical judgement). We assessed the relative contribution of each tool in detecting pulmonary TB under routine conditions. Of 606 participants, 121 (20%) were detected as pulmonary TB: 46 (38%) by microscopy, 38 (31%) by Xpert alone and 37 (31%) on clinical and radiological grounds; 41 (65%) were detected by both Xpert and microscopy. One patient had rifampicin resistance. Although Xpert detected approximately twice as many TB cases as microscopy (n = 79, 65%), clinical judgement remained favoured by clinicians even when smear and Xpert were negative.


En plus d'un protocole de diagnostic de routine (examen microscopique des frottis, cliché thoracique et évaluation clinique), on a offert Xpert® MTB/RIF à des patients consécutifs suspects de tuberculose (TB) qui présentaient à deux hôpitaux du Pakistan au cours de la période avril­mai 2012. Nous avons évalué la contribution relative de chaque outil à la détection de la TB pulmonaire dans les conditions de routine. Sur 606 participants, 121 (20%) ont été diagnostiqués comme TB pulmonaire : 46 (38%) par l'examen microscopique, 38 (31%) par Xpert seul, et 37 (31%) sur une base clinique et radiologique ; 41 (65%) ont été détectés par l'examen microscopique et Xpert. Chez un patient, on a trouvé une résistance à la rifampicine. Quoique l'Xpert ait détecté approximativement deux fois le nombre de cas de TB détectés par l'examen microscopique (n = 79, 65%), le jugement clinique reste favorisé par les cliniciens, même lorsque le résultat du frottis et de l'Xpert est négatif.


En dos hospitales de Paquistán se propuso a un grupo de pacientes con presunción de tuberculosis (TB) que acudieron de manera consecutiva entre abril y mayo del 2012 la prueba Xpert® MTB/RIF, además del protocolo diagnóstico corriente (que comportaba la baciloscopia, la radiografía de tórax y la evaluación clínica). Se analizó la contribución relativa de cada instrumento en el diagnóstico de la TB pulmonar en las condiciones corrientes. De los 606 participantes, en 121 (20%) se estableció el diagnóstico de TB pulmonar de la siguiente manera: en 46 casos (38%) por microscopia, en 38 (31%) mediante la prueba Xpert sola y en 37 casos (31%) con base en las características clínicas y radiográficas; 41 (65%) fueron detectados por microscopia y Xpert. Un paciente exhibió resistencia a rifampicina. Si bien la prueba Xpert permitió el diagnóstico de cerca del doble de casos de tuberculosis que la baciloscopia (n = 79, 65%), el juicio clínico predomina aun en la decisión de los médicos, incluso frente a un resultado negativo de la baciloscopia y la prueba Xpert.

RESUMEN

This case report describes a solitary fibrous tumour presenting as a pedunculated mass arising from an almost completely atretic right middle lobe of lung. The intraoperative findings and pathologic diagnostic criteria used are described. To our knowledge, this is the first case report of a solitary fibrous tumour associated with partial lung atresia.

RESUMEN

PURPOSE: The purpose of this large-animal study was to assess the safety and effects of negative pressure therapy (NPT) when used as temporary abdominal closure in the immediate post-decompression period after abdominal compartment syndrome (ACS). METHODS: Using a hemorrhagic shock/resuscitation and mesenteric venous pressure elevation model, ACS was physiologically induced in 12 female Yorkshire swine. At decompression, animals were allocated to either NPT (n = 6) or Bogota bag (n = 6) as temporary abdominal closure and studied for a period of 48 h or until death. Outcomes measured included morbidity and mortality, as well as hemodynamic parameters, ventilator-related measurements, blood gases, coagulation factors, and organ (liver, kidney, lung, and intestinal) edema and histology at the time of death/sacrifice. RESULTS: All animals developed ACS. Early application of NPT was associated with decreases in mesenteric venous and central venous pressure, and significantly increased drainage of peritoneal fluid. In addition, there was no increase in the incidence of mortality, recurrent intra-abdominal hypertension/ACS, or any deleterious effects on markers of organ injury. CONCLUSIONS: Early application of NPT in this porcine ACS model is safe and does not appear to be associated with an increased risk of recurrent intra-abdominal hypertension. The results of this animal study suggest that the application of NPT following decompression from ACS results in greater peritoneal fluid removal and may translate into augmented intestinal edema resolution secondary to more favorable fluid flux profiles.
