Avoiding confusion in high flow oxygen therapy concepts

Oxygen therapy is the main supportive treatment in hypoxemic respiratory failure and has traditionally been delivered using low and high flow devices. However, the maximal flow rates that these devices can deliver are limited because of the insufficient heat and humidity provided to the gas administered. Low flow devices such as the nasal cannula, conventional face mask and reservoir bag deliver a flow rate of up to 15 L/min by administering more variable oxygen fractions (FiO2), depending on the patient’s respiratory pattern, peak inspiratory flow and characteristics of the devices. Conventional high flow devices, such as venturi type masks, utilize a constant flow of oxygen through precisely sized ports, entraining the ambient air, using the Bernoulli principle, providing a more constant inspired oxygen fraction. However, they are less tolerated than nasal cannulas because they are less comfortable and the insufficient humidification and heating of the gas delivered [1]. In the last two decades, new devices have been developed to administer high humidified and heated flow through a nasal cannula (HFNC) that also allows the delivery of oxygen with a known FiO2 up to 100%. In the literature, this technique has also been called mini CPAP (continuous positive airway pressure), transnasal insufflation, high nasal flow ventilation, high flow oxygen therapy, and high flow nasal cannula oxygen therapy [2]. It is considered that high flow nasal cannula has certain benefits compared to those of oxygen therapy previously detailed. HFNC manages a flow of more than 30 L/min, which is able to surpass the peak inspiratory flow of the patient, being able to reach values ​​between 60-80 L/min depending on the flow used. The gas source, which may be delivered by an air/oxygen blender, fans, or a flow generating turbine, is connected by an active humidifier to a nasal cannula and the FiO2 can be adjusted independently of the flow. From a clinical point of view, there is some confusion between venturi and high flow nasal cannula devices. In the literature, both have been considered as high flow oxygen therapy devices. In our opinion this is not appropriate because the high nasal cannula flow is much more than a simple system for administering oxygen therapy [3]. Venturi-type masks provide the patient with a gas mixture with a controlled FiO2, but do not exert additional benefits on the ventilator mechanics of the patient. Nevertheless, HFNC allows the delivery of a high flow, which can also add oxygen therapy, providing a series of physiological effects that imply an active treatment to respiratory failure. Effects related to HFNC include the following: 1. Delivery of higher and more stable FiO2 values, ​​because the flow delivered is greater than the patient’s inspiratory demand. 2. The anatomical dead space decreases by washing the nasopharynx, consequently increases alveolar ventilation. This improves the thoracoabdominal synchrony. 3. Respiratory work decreases because it acts as a mechanical stent in the airway and markedly attenuates inspiratory resistance. 4. The gas administered is warmed and humidified, improving mucociliar clearance, reducing the risk of atelectasis, improving ventilation perfusion and oxygenation ratio. 5. There is a CPAP-like effect. The dynamic positive espiratory airway pressure generated by HFNC reaches a value between 6-8cmH2o depending on the flow and the size of the cannula. This positive pressure distends the lungs and ensures their recruitment. 6. Pulmonary end-expiratory volume is higher with HFCN than with conventional high-flow oxygen therapy. 7. In addition, the technique is considered easy and simple for the medical staff and nurses, and can be used in different areas (emergency, hospitalization, critical care unit, weaning centers) and even at home [4]. Currently available evidence has demonstrated that HFNC therapy is an alternative for the treatment of acute hypoxemic respiratory failure, hypercapnic respiratory failure, acute heart failure, as rescue therapy preventive therapy in post-extubation respiratory failure and in specific conditions such as bronchoscopy [5]. We believe that high-flow nasal cannula treatment should not be confused with high flow oxygen therapy of venturi masks. According to detailed mechanisms of action, HFNC is not limited to being only an oxygen therapy system but also behaves as a true treatment that can be used in different clinical scenarios, generating physiological benefits that result in the reduction of respiratory work. In addition, in venturi type masks, the air is not humidified and complications such as dryness and nasal pain are common, generating a poor tolerance to oxygen therapy. The benefits of proper humidification and heating of the gas delivered with HFNC therapy allow better comfort and tolerance of the patient with easy adherence to the treatment. All this contributes to making HFNC be considered a technique of choice in patients with hypoxemic respiratory failure. The growth in its use associated with easy acceptance for patients and the expansion in its application show us that HFNC is a promising therapy.

Successful treatment of late-onset pulmonary hypertension after atrial septal defect operation with macitentan: Our center experience

Published on: 17th August, 2018

OCLC Number/Unique Identifier: 7844628408

Background: Macitentan significantly improves pulmonary hemodynamics and survival in patients with primary pulmonary hypertension (PPH). Its beneficial effect, however, may be blunted due to the adverse impacts such as anemia and peripheral edema. Pulmonary arterial hypertension (PAH) is a significant consequence of congenital heart disease (CHD). Its presence and severity are associated with increased morbidity and mortality. We tried to evaluate that the effectiveness of the macitentan in patients with late-onset pulmonary hypertension after atrial septal defect operation in our center. Methods: The effect of a single dose of macitentan (10 mg) on pulmonary hemodynamics, functional capacity was examined in four patients with late-onset pulmonary hypertension after atrial septal defect operation. Results: The macitentan significantly improved mean pulmonary artery pressure (MPAP), cardiac output (CO), tricuspid annular plane systolic excursion (TAPSE), right ventricle systolic wave(RVS’), 6-minute walking test and NT-proBNP levels compared with before treatment. Conclusions: Macitentan can be used in patients with late-onset pulmonary hypertension after shunt operation especially atrial septal defect.

Effect of diabetes mellitus on the Pulmonary Function Tests in Sudanese Diabetic Patients

Published on: 29th August, 2018

OCLC Number/Unique Identifier: 7856188599

Background: Diabetes mellitus is a leading cause of illness and death. Pulmonary function test PFT has assumed a key role in epidemiological studies investigating the incidence, natural history and causality of lung disease. Methods: A cross sectional study was conducted in The National Ribat Teaching Hospital and Jabir Abualiz Specialized Diabetes Center in Khartoum state to measure the respiratory muscle power in 31 diabetic patients (case group) and 30 non-diabetics patients (control groups). Pulmonary function tests were measured by using Digital Spirometer-Micro-Plus version. Results: Lung function parameters between diabetic patients and their matched control group show no significant differences between the means of FVC, FEV1 and FEV1/FVC. However, diabetic patients showed significant reduction in PEFR. Conclusions: Exercise and well control of diabetes helped in preserving normal respiratory muscle power. Continuous reasonable exercise with good control is highly recommended for all diabetics.

COPD and low plasma vitamin D levels: Correlation or causality?

Published on: 27th October, 2018

OCLC Number/Unique Identifier: 7905962979

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death and its prevalence and incidence is also related to smoking behavior [1]. COPD is still a chronic inflammatory and progressive disease caused by multifactorial agents including environmental pollutants [2]. Besides that, it is emerging that endogenous epigenetic factors induced by lifestyle and environment [3] could play a role in the etiopathogenesis of the disease [4]. In the last years, several authors suggested that low vitamin D levels seem to be related with the increase of COPD manifestations [5]. Moreover, a multicentre, double-blind, randomised controlled trial documented that vitamin D supplementation protects against moderate or severe exacerbation of the disease, but not by upper respiratory infections [6]. However, low levels of vitamin D can be extended to many other diseases, including multiple sclerosis, diabetes, colon rectal cancer, headache or drug use [7-11]. Moreover, it is also important to remember that Vitamin D deficiency is common in high latitude regions, such as northern Europe, New Zealand, northern USA, and Canada where weaker ultraviolet B rays is not able to produce enough vitamin D. Finally, methodological factors (using low sensitivity methods) could contribute to misleading evaluation of circulating vitamin D levels. In any case, here we shall remind that vitamin D has a fundamental role in immunity [12]. In particular, it has been reported that vitamin D is able to shift the pro-inflammatory T-helper cell 1 to anti-inflammatory T-helper cell 2 [13]. Therefore, benefits of vitamin D supplementation in chronic diseases which directly or indirectly affect immune system are obvious. Today, the burden of COPD in never smokers is higher than previously believed. Therefore, more research is needed to unravel the characteristics of non-smokers COPD [1]. Notably, vitamin D levels are reported to be significantly lower in smoker’ssubjects than in non-smokers ones [14]. Therefore, low plasma vitamin D levels in COPD seems to be more a causality than a correlation.

Peculiarities of photon emisson of whole non-diluted human blood obtained from healthy donors and patients with some diseases

Published on: 31st December, 2018

OCLC Number/Unique Identifier: 7991708311

Blood plays an important role in oxygen absorption and its transfer to organs and tissues in vertebrates, as well as in a number of invertebrate species. Numerous interactions between cellular and non-cellular blood components constantly occur. A special role in these interactions belongs to erythrocytes and leukocytes, between which oxygen is constantly exchanged and activated, which we showed directly in whole blood. Blood is a liquid tissue, which is a complex cooperative system and has many inherent functions and the most important one is the ability to maintain the homeostasis of the body. Our experience has shown that despite its high optical density, undiluted blood of humans and animals can be a source of radiation due to the transformation of the energy of electron-excited (EEE) states and secondary processes occurring in the whole blood system. Parameters of this radiation - ultra-weak photons emission (UWPE) from blood - depend upon its physiological properties and reflect the physiological state of a donor. Analysis of UWPE from non-diluted blood is a simple and sensitive method that allows to monitor the course of treatment of a patient. In spite of high opacity of non-diluted blood it may be a strong source of UWPE both in the presence and absence of UWPE enhancers. Analysis of patterns of UWPE from blood reveals its highly non-linear, stable non-equilibrium and cooperative properties. Characteristic of a living system.

Dysfunctional breathing in children

Published on: 30th May, 2020

OCLC Number/Unique Identifier: 8607009162

Objective: Dysfunctional breathing (DB) refers to abnormal patterns of breathing. No gold standard exists for diagnosis. In clinical practice we regularly see children with functional breathing problems. We collected data from this patient group to gain more insight into the characteristics of children with dysfunctional breathing. Methods: We composed a retrospective, cross-sectional study. The population consisted of children referred to a physiotherapist by a pediatrician due to suspected dysfunctional breathing. Data from 2013-2015 were collected from patient files, selected according to patterns and onset of symptoms, concomitant asthma, Nijmegen questionnaire (NQ) score, maximum exercise capacity and breathing pattern. Results: A total of 201 patients were included in the study, 66% of whom were female. The mean age was 13.9 years; 26% of the children were overweight. The most frequently reported symptoms were breathlessness, chest pain/tightness and dizziness. Fifty-two percent had a NQ score ≥23, mainly female. Twenty-eight percent of the children scored < p5 for their age on maximum exercise capacity; this proportion was substantially higher among males. Of the total population, 78% scored < p50 for their age. Subgroups with a higher body mass index (BMI) showed lower maximum exercise capacity. Children presenting with pulmonary symptoms were primarily misdiagnosed with asthma. Conclusion: Dysfunctional breathing is a common cause of respiratory complaints. Most children with dysfunctional breathing have a high BMI and are in poor physical condition, which suggests a clinically relevant comorbidity and possible options for therapy. Children are often falsely diagnosed with asthma; better recognition will decrease unnecessary medication use.Introduction

Pulmonary Involvement in COVID-19 and ‘Long Covid’: The Morbidity, Complications and Sequelae

Published on: 15th June, 2021

Introduction: the perennial pandemic: There are serious challenges posed by the SARS-CoV-2 virus and COVID-19 as the disease. With the persistence of the pandemic over one and half year, it is being feared that the COVID-19 may have become the new reality associated with human existence world over and the mankind may have to live with it for years or even decades. Further, the grievous nature of the disease is evolving further with genomic changes in the virus in form of mutations and evolution of variants, with enhanced infectivity and probably virulence. Acute and chronic phases of COVID-19: Epidemiologically, it is becoming clear that apart from the advanced age and pre-existing conditions, such as diabetes, cardiovascular, pulmonary, and renal diseases, certain constituent factors render some patients more vulnerable to more severe forms of the disease. These factors influence the COVID-19 manifestations, its course, and later the convalescence period as well as the newly defined ‘Long COVID phase. The substantial continuing morbidity after resolution of the infection indicates persisting multisystem effects of ‘Long Covid’. Lung damage associated with COVID-19: COVID-19 is primarily a respiratory disease presenting with a broad spectrum of respiratory tract involvement ranging from mild upper airway affliction to progressive life-threatening viral pneumonia and respiratory failure. It affects the respiratory system in various ways across the spectrum of disease severity, depending on age, immune status, and comorbidities. The symptoms may be mild, such as cough, shortness of breath and fevers, to severe and critical disease, including respiratory failure, shock, cytokine crisis, and multi-organ failure. Implications for the post-COVID care: Depending on the severity of respiratory inflammation and damage, as well as associated comorbidities, duration of injury and genetics, the progressive fibrosis leads to constriction and compression of lung tissues and damage to pulmonary microvasculature. Consequently, the COVID-19 patients with moderate/severe symptoms are likely to have a significant degree of long-term reduction in lung function. Depending on the severity of the disease, extensive and long-lasting damage to the lungs can occur, which may persist after resolution of the infection. Managing the long COVID’s challenges: Given global scale of the pandemic, the healthcare needs for patients with sequelae of COVID-19, especially in those with lung affliction are bound to increase in the near future. The challenge can be tackled by harnessing the existing healthcare infrastructure, development of scalable healthcare models and integration across various disciplines with a combination of pharmacological and non-pharmacological modalities. Following clinical and investigational assessment, the therapeutic strategy should depend on the disease manifestations, extent of damage in lungs and other organs, and associated complications.

Organizing pneumonia as the initial presentation in rheumatoid arthritis – A case report

Published on: 25th June, 2021

OCLC Number/Unique Identifier: 9124705182

Organizing pneumonia (OP), can be seen in association with lung injury, infection, drug intoxication, and connective tissue diseases. Patients of rheumatoid arthritis (RA) are prone to develop interstitial lung disease (ILD), but the pulmonary involvement usually occurs several years after the joint manifestations. Only in about 10% cases of RA, the initial manifestation of the disease can be in the form of interstitial lung disease. OP as the initial manifestation of RA is extremely uncommon occurrence. Here is presented a case of 52-year-old male who presented with OP as the initial manifestation of RA. On investigation, the RA factor and anti-CCP Antibodies were positive. Based on clinical, radiological and histopathological findings the diagnosis was established.

A Case series on Asthma-COPD overlap (ACO) is independent from other chronic obstructive diseases (COPD and Asthma)

Published on: 30th July, 2021

OCLC Number/Unique Identifier: 9157820954

As we know that, Asthma and chronic obstructive pulmonary diseases are well characterized diseases, they can co-exist as asthma-COPD overlap (ACO). The co-existence of asthma-chronic obstructive pulmonary disease overlap (ACO) in chronic obstructive pulmonary disease (COPD) patients is often unrecognized. In patients with a primary diagnosis of COPD or Asthma, the identification of ACO has got implication for better prognosis and treatment. Such patients experience frequent exacerbations, poor quality of life, rapid decline in lung function and high mortality than COPD or Asthma alone. Inhalational steroids provide significant alleviation of symptoms in such patients and some studies suggest that the most severe patients may respond to biological agents indicated for severe asthma. Patients who have asthma with a COPD component tend to present with severe hypoxia because of Irreversible/fixed airway obstruction and impairment of the alveolar diffusion capacity by emphysematous changes. In contrast, patients with COPD who have an asthma component not only have exertional dyspnoea but also develop paroxysmal wheezing or dyspnoea at night or in the early morning. The criteria to diagnose asthma-COPD overlap (ACO) include positive bronchodilator response, sputum eosinophilia or previous diagnosis of asthma, high IgE and/or history of atopy. There is scarcity of literature available in country like India. We highlight the importance of identification of Asthma COPD overlap as different phenotype from COPD or asthma alone as it is challenging to diagnose ACO in India. We report 3 cases having both the features of asthma and COPD, later diagnosed with Asthma-COPD overlap.

Pulmonary mucormycosis in post-pulmonary tuberculosis as an emerging risk factor: A rare case report

Published on: 30th July, 2021

OCLC Number/Unique Identifier: 9272372142

Pulmonary mucormycosis is an uncommon pulmonary fungal disease, which is commonly seen in immunocompromised individuals. It is caused by fungi of class Zygomycetes. It constitutes the third most common invasive fungal infection following aspergillosis and candidiasis. Risk factors include patients with hematological malignancies, diabetes mellitus, and immunocompromised states. It is difficult to diagnose early due to non-specific clinical presentation and delay in treatment associated with greater mortality. As we know that Tuberculosis and HIV are highly prevalent in country like India. Post pulmonary tuberculosis is emerging as a risk factor for Pulmonary mucormycosis in the developing countries like India. Patients with non-resolving pneumonia are generally misdiagnosed as Pulmonary tuberculosis. The diagnosis of Pulmonary Mucormycosis is based upon demonstration of fungal hyphae in the clinical specimen. We highlight the importance of clinical suspicion in these cases for early diagnosis and early treatment initiation can reverse morbidity and mortality associated with Pulmonary Mucormycosis. We report 2 cases of Pulmonary mucormycosis present in post-pulmonary tuberculosis patients.

“Fatty Lungs”: An uncommon case of Autoimmune Pulmonary Alveolar Proteinosis

Published on: 5th August, 2021

OCLC Number/Unique Identifier: 9157841457

Pulmonary Alveolar Proteinosis (PAP) is a rare lung disease characterized by excessive accumulation of surfactant lipids and proteins in alveoli and terminal airways. It is caused by impaired GM-CSF signaling [1]. Surfactant is synthesized and secreted by alveolar type II epithelial cells, and removed by uptake and catabolism by these cells, and the alveolar macrophages. Patients with PAP usually describe gradual onset of progressive exertional dyspnea and non-productive cough. However, an asymptomatic presentation is observed in up to 25% of cases, even in the presence of diffuse radiographic changes. Three recognized subtypes exist. Autoimmune PAP is associated with neutralizing GM-CSF autoantibodies and accounts about 90% of cases. Secondary PAP may occur in the context of any disease that reduces the abundance or functionality of alveolar macrophages, resulting in impaired surfactant clearance. Congenital PAP is the result of genetic mutations that disrupt GM-CSF signaling, including mutations in the α- or β-chains of the GM-CSF receptor [1-3].

Use of Orthodeoxia by pulse Oximetry in the detection of Hepatopulmonary Syndrome

Published on: 4th August, 2017

OCLC Number/Unique Identifier: 7317595208

Chronic Hepatic deficiency due to the ingestion of alcohol remains as one of the main causes of morbidity and mortality in our country. From it a variety of complications arise, one of them is the Hepatopulmonary Syndrome, which usually goes unnoticed and undiagnosed; this syndrome is distinguished by the presence of hypoxemia and pulmonary vasodilation. The gold standard to establish a diagnostic is contrast-enhanced Echocardiogram. No pathognomonic sign is known for this syndrome, which leads the present elaboration to evaluate the use of orthodeoxia by pulse oximetry as a screening test in the detection of Hepatopulmonary Syndrome cases.

The revolution of cardiac surgery evolution Running head: Cardiac surgery evolution

Published on: 28th August, 2017

OCLC Number/Unique Identifier: 7317598809

From the first case of primitive cardiac surgery (CS), treatment of stab wound of the heart (Dr. Daniel Hale Williams, 1893), to recent surgical procedures and device implantations for end-stage heart failure (HF), the CS has grown and emerged in the public health more and more [1]. The heart valve disease had interested immediately since the non-cardiopulmonary era because of the multitude of rheumatic patients and congenital valve disease. In the 1952, Hufnagel implanted the first valve in descending aorta and it was the sign of the first step of the CS evolution. New prosthesis and heart valve techniques were tested between 1970 and 2000 with optimal results in patients’ quality of life and survival, at the same time of CPB evolution. Whilst, the evolution of heart valve surgery had stimulated new devices, prosthesis and the development of minimally invasive surgery, this was partially diminished by the spreading of trans catheter valve implantation. In the 2002, Dr. Alain Crabbier described a non-surgical prosthetic valve implantation firstly: it was the revolution of CS evolution [2]. The transcatheter valve implantation has evolved and spread rapidly with multiple approaches femoral to apical, aortic, axillary and carotid, and many suitable and technological devices. The higher and higher risk patients, the needs to avoid surgical complications, the evolution of available devices and the fabrication of new technologies have increased the efforts to improve trans catheter valve implantation [3]. The recent article of Loyalka et al, described a special case of tricuspid valve in valve replacement with Sapien 3, an innovative and alternative therapeutic choice to a tricuspid valve degeneration [4]. Instead, Sawara et al [5], documented as trans catheter aortic valve implantation for a failing surgical bio prosthesis or native aortic valve regurgitation has become an alternative for patients at high risk for redo surgical aortic valve replacement or aortic regurgitation since now off-label: that was a reliable and significant results in the era of trans catheter valve implantations. What would we attend from the future? In the most surgical centres, the trend were a significant decrease in patients undergoing to open-heart valve surgery compared to trans catheter valve implantation. Maybe the new ongoing studies of lower and mild-risk patients undergone to transcatheter procedure would open either a deeper collaboration of the heart team and a new therapeutic perspectives in the public health with a shift to more minimally invasive procedures, less day of hospitalization and I don’t see why not less costs for public health.

Endogenous Ligands of Toll Like Receptors: A Danger Signal to the Brain Memory at High Altitude

Published on: 15th October, 2018

OCLC Number/Unique Identifier: 7877908260

Sojourn to high altitude may affect various human systems if proper acclimatization not followed. If acclimatization failed, sojourners may suffer with high altitude sickness such as acute mountain sickness (AMS), high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE). Although a sojourner’s tolerance to high altitude hypoxia varies according to differences in physiology and physical conditioning. Acute mountain sickness may cause headache, insomnia, dizziness, nausea, vomiting and fatigue. While HACE is more serious stage where brain swelling occurs and it is potentially fatal. A sojourner with HACE may experience confusion, amnesia, delusions, and loss of consciousness. Staying in high altitude (above 9000 feet) environment poses low oxygen supply (hypobaric hypoxia) to the different body organs including brain.

SARS-CoV-2 infection and phylogenetic analysis with the risk factors in human body alongside the pulmonary effects and medication

Published on: 6th November, 2020

OCLC Number/Unique Identifier: 8698222103

Related the extremely transmittable abilities of SARS-CoV-2,a harmonious virus to the bat CoV, gets transmitted by three principal processes-- the inhalation of droplets from the SARS-CoV-2 infected person, contacting to the person, and by the surfaces and materials defiled with the virus. Whereupon bat Coronavirus is mostly like the pandemic causing virus SARS-CoV-2, bats are often deliberated and figured out as a possible primary host although no intermediate has not been defined yet in the wherewithal of transmission. The Spike Glycoprotein plays an important role in the case of penetration with the assistance of the ACE2 receptor and the Receptor Binding Domain. In the human body, infiltrating the nucleic acid into host cells, SARS-CoV-2 attacks one cell and one by one into the whole human body; therefore, infected cases are found symptomatic and asymptomatic considering the immune power. Patients with cardiovascular disease or diabetes proceed with their treatment with ACE2 often; therefore, there might be a high chance of getting infected. Whereas the SARS-CoV-2 infects the blood and then lungs, Antigens improvement can be better in order to avoid high-complicated effects. Currently, no vaccination or no accurate cure and treatment has not been defined. An explanation with analysis on SARS-CoV-2 has been performed from the aspect of virology, immunology and molecular biology. Several relevant figures have been included hereby in order to a better understanding of the very concept.

A rare case: Congenital Megalourethra in prune belly syndrome

Published on: 30th January, 2018

OCLC Number/Unique Identifier: 7355941035

Introduction: Prune Belly syndrome is a disease characterized by abdominal muscle defect, bilateral cryptorchidsim and urinary system anomalies (reflux megaureter, hydronephrosis, etc.). Pulmonary, cardiac, and gastrointestinal anomalies may also be present. Management of these rare cases is very important. In this case, the clinical course of a patient with Prune Belly syndrome with megaurethra is presented. Case: The patient from the first gestation and parturition with birth weight of 2500 g and 38 weeks was hospitalized because of the bilateral hydronephrosis. His physical examination revealed undescended testicles and a large penis. The abdominal muscles were not very atrophic. The size of the kidney was small, bilateral hydroureteronephrosis and wide posterior urethra on the ultrasound. Renal function tests were progressively disturbed and the patient underwent cystourethroscopy for diagnostic purposes in terms of posterior urethral valve. A large diverticulum was found in anterior urethra. Prune Belly Syndrome was thought because the orifices were in appearance of reflux. The vesicostomy was applied. After vesicostomy the renal function tests got better but he was hospitalized due to urosepsis two times. In cystoscopic examination, the diverticulum in the urethra was filled with urine and the drainage was very slow. Phimosis was opened with dorsal slit technique. Cutaneous urethrostomy was proximal to the anterior diverticulum. Conclusion: Prune Belly syndrome should be considered in patients with megaurethra and postrenal or renal insufficiency although there are no obvious clinical findings. In Prune Belly cases, via a large penis with obstruction signs, anterior urethral diverticulum should be considered.

The role of robotic segmentectomy for non-small cell lung cancer

Published on: 6th October, 2020

OCLC Number/Unique Identifier: 8682303248

Segmentectomy may be applied to all segments; superior segmentectomies (lower lobe superior segments for both lungs), lingulectomies (two segments forming lingulas of upper left lobe) and basal segmentectomies (segments other than superior segment for both lungs). In lung segment resections; segmentectomy has an equivalent morbidity, recurrence and survival rate compared to lobectomy, in patients with stage I lung cancer, tumors smaller than 2 cm and within the segmental anatomical limits. Segmentectomy also contributes more to preserving lung function and exercise capacity than lobectomy. In tumor resection; especially in patients with advanced age, insufficient performance or insufficient cardiopulmonary reserve, 2 cm in diameter and acceptable segmental margins may be provided. Limited long-term results show oncological results of robotic approach similar to open and VATS approaches. Robotic approach facilitates surgery with more intuitive movements, greater flexibility and high definition, three-dimensional vision. However, high cost and lack of touch sense are main disadvantages of robotic surgery. New studies are needed to assess quality of life, morbidity, oncological results and cost effectiveness. However, considering development of technology in our age and fact that many surgical robot brands will be released in the near future, it is predicted that disadvantages of robotic surgery will be minimized in the near future. This article reviews experience of segmentectomy in non-small cell lung cancer and discusses benefits and limitations of robotic segmentectomy.

OCLC Number/Unique Identifier: 8286573110

Agranulocytosis is one of the common reasons of consultation in hematology. It’s life-threatening because of an infection risk. The metamizole is a drug, known for its potential rare danger of inducing a severe agranulocytosis. However, it remains widely used because of its beneficial effect analgesic and antipyretic. We report in this study, a case of a girl who was 16 years old, referred for severe agranulocytosis, and appeared two weeks after treatment with Novalgin. The clinico-biological symptoms were dominated by Streptococcal septicemia with an infectious pulmonary and digestive focus. The blood cell count confirmed a severe agranulocytosis with total disappearance of neutrophils. Despite broad-spectrum antibiotic therapy and stimulation with hematopoietic growth factor, the clinical evolution was fatal in the short term. What motivates us to add this case to those of the literature in order to remind practitioners about the danger of this drug, and to promote has doubled of vigilance during use.
