Characteristics and predictors of burnout among healthcare professionals: a cross-sectional study in two tertiary hospitals.

BACKGROUND: The pattern and impact of burnout among the medical staff are not yet well defined. However, the consequences of burnout are not limited to the healthcare providers but also may affect their family, colleagues and patients in a negative manner. We aimed to assess the characteristics and predictors of burnout among health professionals at two large tertiary hospitals. METHODS: We conducted a cross-sectional study during the period from July 2018 to 31 December 2018. Data, via Maslach Burnout Inventory survey, were collected from physicians and other healthcare workers in two hospitals. RESULTS: A total of 624 responses to questionnaires were analysed. Half of the respondents were physicians, and men constituted the majority. About 10% (95% CI, 7.8 to 12.5) of the respondents satisfied the criteria of burnout. Emotional exhaustion (EE) was observed in 45.7%, depersonalisation (DP) in 26.9% and personal accomplishment (PA) in 41.2% of the respondents. There was a positive correlation between EE and DP (r=0.627, p=0.001), and a weak negative correlation between DP and PA (r=-0.195, p=0.001). Young age, less experience, trauma surgery, lack of habits and getting depressed ≥1 time/week were predictors of burnout. CONCLUSIONS: Burnout affects one-tenth of the health professionals in the tertiary hospitals in Qatar. Physicians are more likely to have higher DP and lower PA, whereas nurses prone to have higher EE. In this study, no gender discrepancy is appreciated and the junior medical staff is at a higher risk of burnout.

Asthma knowledge, care, and outcome during pregnancy: The QAKCOP study.

Asthma is the most common chronic medical condition affecting pregnancy. Optimizing asthma management in pregnancy is paramount for the well-being of both the mother and the baby. The primary objectives of this study were to assess patient's knowledge about asthma, the level of asthma care, and fetal and maternal outcomes among pregnant asthmatic women in this wealthy country with tremendous improvement in maternal and fetal health care. The secondary objective was to identify barriers to asthma control. This was a cross-sectional, face-to-face, prospective study of 80 pregnant women with physician-diagnosed asthma. About 56% of patients reported worsening of their asthma control during pregnancy, of which 52.3% felt this worsening in the third trimester. About 65% of patients had uncontrolled asthma during their pregnancy, and inhaler technique was incorrect in 64.4%. Only 38% of patients knew the difference between controller and reliever asthma medications, 12.7% of patients had received written asthma action plan, 17% had a spirometry done in the previous 5 years, and 3.8% had peak expiratory flow meter at home. The main reasons for uncontrolled asthma were lack of knowledge about right asthma medications in 30% and fear of side effects of inhaled corticosteroids in 19% of patients. No financial reason was reported. Significant associations between total number of pregnancies, poor perception of asthma medications, asthma exacerbation during delivery and poor asthma control were observed. Preeclampsia and congenital anomalies occurred at higher rates than previously reported among general population in this country. The tremendous improvements in maternal health care and socioeconomic status do not seem to be a barrier to the globally recognized poor asthma care in pregnancy. Important strategies are much needed.

Medical thoracoscopy for exudative pleural effusion: an eight-year experience from a country with a young population.

BACKGROUND: With the exception of areas with high prevalence of tuberculosis, medical thoracoscopy is becoming the diagnostic modality of choice for exudative pleural effusions. The aims of this study were to determine the diagnostic yield and safety of medical thoracoscopy for exudative pleural effusions and ascertain the etiology of such effusions in Qatar. METHODS: This is a retrospective-descriptive study of 407 patients who underwent diagnostic medical thoracoscopy for exudative pleural effusions from January, 2008 till December, 2015 at the only tertiary referral center performing this procedure in Qatar. RESULTS: Tuberculosis was the most common etiology of exudative pleural effusions in Qatar accounting for 84.5% of all causes. Around 85% of patients were young males (mean age of 33 ± 12.1 years). The diagnostic yield of medical thoracoscopy for tuberculous pleural effusion was 91.4%. Malignant pleural effusions accounted for 5.2% of cases. Minor bleeding occurred in 1.2% of cases with no procedure-related mortality observed. CONCLUSION: Medical thoracoscopy is a very safe procedure. Tuberculous pleuritis is by far the most common etiology of exudative pleural effusions in Qatar. Closed needle biopsy is a worth consideration as an initial safe, easy and low-cost diagnostic modality for exudative pleural effusions in this country.

Somatic survival and organ donation among brain-dead patients in the state of Qatar.

BACKGROUND: The Qatari law, as in many other countries, uses brain death as the main criteria for organ donation and cessation of medical support. By contrast, most of the public in Qatar do not agree with the limitation or withdrawal of medical care until the time of cardiac death. The current study aims to examine the duration of somatic survival after brain death, organ donation rate in brain-dead patients as well as review the underlying etiologies and level of support provided in the state of Qatar. METHODS: This is a retrospective study of all patients diagnosed with brain death over a 10-year period conducted at the largest tertiary center in Qatar (Hamad General Hospital). RESULTS: Among the 53 patients who were diagnosed with brain death during the study period, the median and mean somatic survivals of brain-dead patients in the current study were 3 and 4.5 days respectively. The most common etiology was intracranial hemorrhage (45.3 %) followed by ischemic stroke (17 %). Ischemic stroke patients had a median survival of 11 days. Organ donation was accepted by only two families (6.6 %) of the 30 brain dead patients deemed suitable for organ donation. CONCLUSION: The average somatic survival of brain-dead patients is less than one week irrespective of supportive measures provided. Organ donation rate was extremely low among brain-dead patients in Qatar. Improved public education may lead to significant improvement in resource utilization as well as organ transplant donors and should be a major target area of future health care policies.

The burden of adult asthma in a high GDP per capita country: the QASMA study.

BACKGROUND: Asthma is a major health problem worldwide. Suboptimal asthma care and poor asthma control are common even in developed countries. Qatar has the highest gross domestic product per capita in the world and high per capita health expenditure. No prior study has assessed the burden of adult asthma in this country. OBJECTIVES: To assess asthma control, patients' level of education about asthma, and level of asthma care in a country with the highest gross domestic product per capita in the world. METHODS: A face-to-face, cross-sectional study of 520 adults with physician-diagnosed asthma conducted in various health care facilities in Qatar. RESULTS: Thirty-three percent, 41%, and 26% of patients had uncontrolled, controlled, and partly controlled asthma, respectively. Only 4.9% of patients had previously received a written asthma management plan, 3.5% had a flow meter at home, and 37.2% had a spirometry performed in the previous 5 years. In addition, 42.9% misunderstood the role of reliever and controller medications. Inhaler technique was incorrect in 47% of these patients. There was a significant association between the type of physician practice and level of asthma control, with worst control being at the general practice level. Moreover, 57.3% of patients had at least 1 asthma-related visit to the emergency department in 1 year and 18.7% had more than 3 visits. CONCLUSION: The very high gross domestic product per capita in Qatar and the high health expenditure per capita do not seem to have led to better asthma care and control. A comprehensive national asthma service improvement program is much needed.

Optimal management, prevalence, and clinical behavior of saddle pulmonary embolism: A systematic review and meta-analysis.

INTRODUCTION: The central location, size, and instability of saddle pulmonary embolism (SPE) have raised significant concerns regarding its clinical, hemodynamic effects as well as optimal management. Pulmonary embolism (PE) guidelines barely address such concerns. We aimed to pool the available data on the clinical behavior and outcomes of SPE and study the effects of various treatment modalities on mortality outcomes. METHODS: PubMed, Scopus, and Google Scholar were searched for articles (any date up to February 28, 2022) reporting patients with SPE. Data on SPE demographics, clinical characteristics, management, and outcomes were extracted and analyzed. RESULTS: Results from all SPE cases: A total of 5251 patients from 194 studies were included in the review. Dyspnea (57 %) was the most prevalent symptom. Massive and submassive PE comprised 9.7 % and 45.8% of cases, respectively. Thrombolytic therapy (TT) was administered in 18.1 %, and thrombectomy was performed in 16 % of cases. SPE-related mortality was observed in 4.6 %, late decompensation in 9.5 %, and PE recurrence in 4.5 % of cases. Female sex (61.5 % vs. 41.3 %, p = 0.019), hypoxemia (90 % vs. 59.2 %, p < 0.001), massive PE features (89.7 % vs. 30.1 %, p < 0.001), associated chronic kidney disease (CKD) (10.3 % vs. 1.4 %, p = 0.002), and the need for mechanical ventilation (28.2 % vs. 13.1 %, p = 0.02) were significantly associated with increased mortality. The use of TT was significantly associated with increased survival (27.1 % vs. 12.5 %, p < 0.001). In a multivariate logistic regression model, massive PE features significantly increased the odds of death (OR: 29.3, CI: 4.86-181.81, p < 0.001), whereas, treatment with anticoagulation (AC) alone (OR: 0.1, CI: 0.027-0.356, p < 0.001), TT (OR: 0.065, CI: 0.019-0.26, p < 0.001), surgical thrombectomy (ST) (OR: 0.047, CI: (0.010-0.23), p < 0.001), or percutaneous thrombectomy (PT) (OR: 0.12, CI: 0.020-0.84, p = 0.032) significantly decreased odds of death. Results from a meta-analysis of observational studies: Meta-analysis of the included 17 observational studies revealed an overall 10 % (95 % CI: 4.56-16.89) SPE prevalence among all PE cases. The overall SPE-related mortality rate was 8 % (95 % CI: 5.26-10.96). Massive PE was observed in 13.3 % (95 % CI: 5.56-23.70), PE recurrence in 5.1 % (95 % CI: 2.22-9.05), and late decompensation in 11 % (95 % CI: 3.43-22.34) of patients. CONCLUSIONS: SPE comprises 10 % of all PE cases. Despite its ominous radiologic appearance, the clinical, hemodynamic, and mortality outcomes of SPE seem comparable to that of other PE types in general. The presence of massive PE features is the main predictor of mortality in SPE patients. AC, TT, ST, and PT are all associated with decreased odds of death from SPE.

Prevalence, Outcome, and Optimal Management of Free-Floating Right Heart Thrombi in the Context of Pulmonary Embolism, a Systematic Review and Meta-Analysis.

Free-floating right-heart thrombus (FFRHT) in the context of a pulmonary embolism (PE) is a rare but serious encounter with no guidelines addressing its management. We performed a systematic review and meta-analysis addressing prevalence, clinical behavior, and outcomes of FFRHT associated with PE. Among the included 397 patients with FFRHT and PE, dyspnea was the main presenting symptom (73.3%). Obstructive shock was documented in 48.9% of cases. Treatment with thrombolytic therapy, surgical thrombectomy, and percutaneous thrombectomy was documented in 43.8%, 32.7%, and 6.5% of patients, respectively. The overall mortality rate was 20.4%. Syncope (p: 0.027), chest pain (p: 0.006), and obstructive shock (p: 0.037) were significantly associated with mortality. Use of thrombolytic therapy was significantly associated with survival (p: 0.008). A multivariate logistic regression model to determine mortality predictors revealed that syncope (OR: 1.97, 95% CI: 1.06-3.65, p: 0.03), and obstructive shock (OR: 2.23, 95% CI: 1.20-4.14, p: 0.01) were associated with increased death odds. Treatment with thrombolytic therapy (OR: 0.22, 95% CI: 0.086-0.57, p: 0.002) or surgical thrombectomy (OR: 0.35, 95% CI: 0.137-0.9, p: 0.03) were associated with reduced death odds. Meta-analysis of observational studies revealed a pooled prevalence of FFRHT among all PE cases of 8.1%, and overall mortality of 23%. Although uncommon, the presence of FFRHT in the context of PE is associated with high obstructive shock and mortality rates. Favorable survival odds are observed with thrombolytic therapy and surgical thrombectomy. Data are derived from case reports and observational studies. Clinical trials elucidating these findings are needed.

Saddle versus non-saddle pulmonary embolism: differences in the clinical, echocardiographic, and outcome characteristics.

The central location, the size, and instability of saddle pulmonary embolism (PE) have raised considerable concerns regarding its hemodynamic consequences and the optimal management approach. Sparse and conflicting reports have addressed these concerns in the past. We aimed to evaluate the clinical presentation, hemodynamic and echocardiographic effects, as well as the outcomes of saddle PE, and compare the results with those of non-saddle type. This was a retrospective study of 432 adult patients with saddle and non-saddle PE. Overall, 432 patients were diagnosed with PE by computed tomography pulmonary angiography (CTPA). Seventy-three (16.9%) had saddle PE, and 359 had non-saddle PE. Compared to those with non-saddle PE, patients with saddle PE presented more frequently with tachycardia (68.5% vs. 46.2%, P= .001), and tachypnea (58.9% vs. 42.1%, P= .009) on admission, required more frequent intensive care unit (ICU) admissions (45.8% vs. 26.6%, P= .001) and thrombolysis/thrombectomy use (19.1% vs. 6.7%, P= .001), and were at more risk of developing decompensation and cardiac arrest after their initial admission (15.3% vs. 5.9%, P= .006). On echocardiography, right ventricular (RV) enlargement (60% vs. 31.1%, P= .000), RV dysfunction (45.8% vs. 22%, P= .000), and RV systolic pressure (RVSP) of greater than 40 mmHg (61.5% vs. 39.2%, P= .003) were significantly more observed with saddle PE. The two groups did not differ concerning the rates of hypotension (17.8% vs. 18.7%, P= .864) and hypoxemia (41.1% vs. 34.3%, P= .336) on admission and mortality rates. A logistic regression model indicated that the use of oral contraceptive pills (OCP), RVSP > 40 mmHg, and development of hypotension and decompensation following admission were associated with an increased likelihood of having saddle embolus. Saddle PE accounts for a higher proportion among all PE cases than previously reported. Patients with saddle PE tend to present more frequently with adverse hemodynamic and echocardiographic changes and decompensate after their initial presentation. OCP use, development of hypotension, and decompensation following admission and RVSP > 40 mmHg are significant predictors of saddle PE. These characteristics should not be overlooked when managing patients with saddle PE.

Electronic Cigarette or Vaping Product Use-Associated Lung Injury in a Previously Healthy Young Male.

Vaping (i.e., the use of electronic cigarettes) has been gaining popularity among people for the past few years, perhaps due to the misconception that its use is less harmful than traditional cigarettes. Although the long-term effects of these products are still unknown, it has been shown that they can be implicated in acute lung injury in healthy people. In 2019, an epidemic of severe acute lung injury was reported in the United States, and it was linked to vaping or electronic cigarette use and was referred to as e-cigarette or vaping product use-associated lung injury (EVALI). Here, we present the first case of EVALI in the state of Qatar.

Featuring Trends in the Epidemiology of Lung Cancer Following the Publication of the National Cancer Strategy in Qatar.

OBJECTIVES: Qatar has witnessed significant reforms in its health care system, including the care of cancer patients. In 2011, the National Cancer Strategy was released with the aim to deliver a high standard of care to cancer patients across the country. We sought to investigate the featuring trends in the epidemiological and clinical characteristics of lung cancer in Qatar following the publication of the National Cancer Strategy. METHODS: We conducted a retrospective cohort study documenting the epidemiological and clinical characteristics of primary lung cancer cases in Qatar diagnosed from 1 January 2011 to 31 December 2018. RESULTS: The overall age-standardized incidence rate was 8.7 per 100 000 persons (11.6 per 100 000 and 5.4 per 100 000 persons for males and females, respectively). The one, three, and five-year overall survival rates were 67.0%, 48.0%, and 28.0%, respectively. The three-year overall survival rates for stages I, II, III, and IV were 97.0%, 78.0%, 52.0%, and 31.0%, respectively. The three-year survival rates for males and females were 43.0% and 64.0%, respectively (p = 0.029), for Qatari and non-Qatari nationals were 42.0% and 49.0%, respectively (p = 0.252), and for smokers and non-smokers were 39.0% and 69.0%, respectively (p ≤ 0.001). The overall age-standardized mortality rate was 5.5 per 100 000 persons. Adenocarcinoma was the most common histologic type. CONCLUSIONS: Despite the low overall lung cancer incidence rate in Qatar, there is a rise in the incidence among females when compared to previous studies. Qatar has favorable five-year lung cancer survival rates compared to many developed and neighboring countries. Policymakers in the country should consider the changing patterns in lung cancer incidence when planning future preventive strategies.

A 23-Year-Old Man with SARS-CoV-2 Infection Who Presented with Auditory Hallucinations and Imaging Findings of Cytotoxic Lesions of the Corpus Callosum (CLOCC).

BACKGROUND Cytotoxic lesions of the corpus callosum (CLOCC) is a rare clinical and radiological syndrome that has been associated with various infectious etiologies. CLOCC are among the recently described neurological associations with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with coronavirus disease 2019 (COVID-19). We report a case of CLOCC in a man with SARS-CoV-2 infection who presented with auditory hallucinations and rapidly developed systemic inflammatory response syndrome (SIRS). CASE REPORT A 23-year-old man with no past medical and psychiatric history presented with auditory hallucinations, restlessness, and suicidal ideations. A nasopharyngeal swab specimen tested using real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay was positive for SARS-CoV-2. A brain MRI revealed an isolated oval-shaped lesion in the splenium of the corpus callosum, with hyperintense signal on diffusion-weighted imaging (DWI) and hypointense on apparent diffusion coefficient (ADC) maps, suggestive of CLOCC. After a dramatic hospital course associated with multiple organ dysfunction syndrome (MODS) and severe intra-abdominal and cerebral bleeding, he developed cardiac arrest and died on hospital day 15. CONCLUSIONS This case highlights the need for increased vigilance for the atypical manifestations of SARS-CoV-2 infection. In addition, it suggests that CLOCC can be considered as a differential diagnosis by clinicians in patients with SARS-CoV-2 infection who present with unexplained neurological and neuropsychiatric symptoms, leading to poor outcome.

Impact of the COVID-19 Pandemic on Clinical Practice, Medical Education, and Research: An International Survey.

OBJECTIVES: Because of the mandatory sanitary measures established during the Covid-19 Pandemic, we have proposed to describe the new clinical, educative, and research practices of an international sample of doctors. METHODS: We have used an online electronic survey of a convenient sample of doctors from 40 countries using a multiple-choice online questionnaire, including three domains.  424 out of 456 respondents provided adequate responses. RESULTS: Most respondents were from medical (51.5%) and surgical (11.8%) specialties. Over half of the respondents practiced in academic centers and one fifth in the private sector. Coronavirus pandemic induced frequent changes in practice, such as seeing fewer patients in clinics than usual (34.9%) and utilization of telemedicine (31.3%). A significant disruption in medical education activities and residents' training was observed, resulting in the cancellation of many activities such as grand rounds, departmental and multidisciplinary meetings, and case conferences with over-reliance on virtual and on-demand educational sessions. The residents' supervision and support were significantly reduced. Almost 16% of respondents were involved in research work on coronavirus pandemic while a third continued their usual research activity, but half were not involved in any research at the time of the survey. CONCLUSIONS: The COVID19 pandemic has promoted new practices in the field as the recourse to telemedicine, virtual conferences, and thematic researches on COVID-19. The unexpected situation has opened new prospects for future doctors' preparation for these new means of practice and learning of medicine.

Rifampicin-Induced Pneumonitis Mimicking Severe COVID-19 Pneumonia Infection.

BACKGROUND Rifampicin-induced pneumonitis is an infrequent occurrence, with only a few cases reported in the literature. Furthermore, this condition constitutes a diagnostic challenge, particularly in the era of COVID-19 infection. Here, we report a case of rifampicin-induced pneumonitis with clinical, imaging, and histological features of acute respiratory distress syndrome (ARDS), which required severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing to exclude a diagnosis of coronavirus disease 2019 (COVID-19) pneumonia. CASE REPORT A 43-year-old man on anti-TB treatment for TB meningitis developed new-onset fever, fatigue, hypoxemic respiratory failure, and bilateral pulmonary opacities. His clinical, chest X-ray, and CT thorax findings of ARDS were similar to both rifampicin-induced pneumonitis and severe COVID-19 pneumonia. However, reverse transcription polymerase chain reaction (RT-PCR) testing from a nasopharyngeal swab and bronchoalveolar lavage (BAL) via the GeneXpert system was negative for SARS-CoV-2. A detailed workup, including lung biopsy, revealed drug-induced pneumonitis as the cause of his presentation. His pneumonitis improved after discontinuation of rifampicin and recurred following the rifampicin challenge. CONCLUSIONS This case highlights the importance of early, rapid, and accurate testing for SARS-CoV-2 during the COVID-19 pandemic for patients presenting with acute respiratory symptoms, so that accurate diagnosis and early patient management are not delayed for patients with treatable causes of acute and severe lung diseases. Timely identification of rifampicin-induced pneumonitis via a high clinical suspicion, detailed workup, and histopathological analysis is required to avoid permanent damage to the lungs.

Fungal Malignant Otitis Externa Involves a Cascade of Complications Culminating in Pseudoaneurysm of Internal Maxillary Artery: A Case Report.

BACKGROUND Pseudomonal infection is the most common cause of malignant otitis externa (MOE), which typically affects elderly diabetic patients. Fungi are a rare cause of MOE. MOE can be life-threatening if not recognized and treated promptly. It can result in a wide spectrum of complications, including skull-base osteomyelitis, cranial nerve palsy, cerebral venous thrombosis, and brain abscess. Pseudoaneurysm formation of the intracranial vessels is a life-threatening complication of MOE that is seldom reported in the literature. CASE REPORT We report the case of a 66-year-old diabetic man with MOE who was initially treated with antipseudomonal antibiotics after negative initial culture results. His MOE resulted in a cascade of complications, including facial nerve palsy, skull base osteomyelitis, and sigmoid sinus thrombosis, and culminated in left maxillary artery pseudoaneurysm formation resulting in massive epistaxis and hemodynamic instability. Endovascular embolization resulted in a successful obliteration of the pseudoaneurysm. A subsequent functional endoscopic sinus surgical (FESS) tissue biopsy confirmed Candida glabrata as the etiological agent. The patient was successfully treated with antibiotics and antifungal and anticoagulation therapy, and was discharged home in good condition. CONCLUSIONS A high index of suspicion for the diagnosis of fungal MOE, particularly in intractable cases of MOE with negative initial cultures, should be maintained. Pseudoaneurysm formation is a life-threatening complication of MOE that is seldom reported in the literature and should be suspected in any patient with MOE who presents with epistaxis or intracranial bleeding.

Diagnostic value of bronchoalveolar lavage in the subset of patients with negative sputum/smear and mycobacterial culture and a suspicion of pulmonary tuberculosis.

BACKGROUND: The diagnostic value of bronchoalveolar lavage in patients with negative sputum/smear for tuberculous bacilli has been well studied. However, its value in the subset of patients with both negative sputum/smear and culture is seldom reported. METHODS: A retrospective study of patients referred for diagnostic bronchoscopy for the suspicion of pulmonary tuberculosis during the period from April 1st, 2015 to March 30th, 2016, and who had negative sputum/smear and culture for tuberculous bacilli. RESULTS: One hundred and ninety patients fulfilled the inclusion criteria. Bronchoalveolar lavage detected further 61/190 (32.1%) pulmonary tuberculosis cases. Bronchoalveolar lavage mycobacterial culture and polymerase chain reaction (positive in 60/190 (31.6%) and 58/190 (30.5%) of patients respectively) provided the highest diagnostic yield, whereas direct smear provided the lowest yield. Bronchoalveolar lavage had a sensitivity of 89.7%, a specificity of 100%, a positive predictive value of 100%, a negative predictive value of 94.6%, and a test accuracy of 96.3% in suspected pulmonary tuberculosis cases with negative sputum/smear and culture. Positive bronchoalveolar lavage yield for tuberculosis was significantly associated with a positive QuantiFERON-TB Gold In-Tube test, positive purified protein derivative skin test, radiological evidence of upper zone abnormality and patient's origin being from the Indian subcontinent. CONCLUSION: Bronchoalveolar lavage should be pursued as a useful diagnostic tool for suspected pulmonary tuberculosis cases when sputum/smear and culture are negative. Its value is higher in the subset of patients with positive QuantiFERON-TB Gold In-Tube test, positive purified protein derivative skin test, upper zone abnormality on radiograph or being from the Indian subcontinent.

Massive Pulmonary Embolism as the Initial Presentation of Acromegaly: Is Acromegaly a Hypercoagulable Condition?

BACKGROUND The clinical presentation in acromegaly is usually insidious, with headaches or visual disturbances being the most common symptoms. Previous studies have shown higher fibrinogen levels, lower protein C and S activity values, and enhanced platelet function in patients with acromegaly compared to a normal population. Nevertheless, the link between hypercoagulability and acromegaly is often overlooked and rarely reported in the literature. CASE REPORT We report a case of a young man with a massive pulmonary embolism as the initial presentation of acromegaly. Extensive workup excluded other causes of thrombophilia. Furthermore, the diagnosis of acromegaly was confirmed by the patient's clinical features as well as laboratory and radiological testing. A literature review on the link between hypercoagulability and acromegaly was performed. CONCLUSIONS This case report shed light on hypercoagulability as an under-recognized serious complication of acromegaly and paves the road for future studies on this topic.

Errors in Aerosol Inhaler Use and Their Effects on Maternal and Fetal Outcomes among Pregnant Asthmatic Women (Subanalysis from QAKCOP Study).

Data on inhaler technique and its effects on maternal and fetal outcomes during pregnancy are seldom reported. The primary objective of this study was to evaluate inhaler technique and identify errors in inhaler use among pregnant women with asthma. Secondary objectives were to identify factors associated with poor inhaler technique and study the association between inhaler technique and maternal and fetal outcomes. This was a cross-sectional, face-to-face, prospective study of 80 pregnant women with physician-diagnosed asthma. Seventy-three and 41 asthmatic pregnant women reported using pressurized metered dose inhalers (pMDIs) and dry powder inhalers (DPIs), respectively. Overall, wrong inhaler technique was observed in 47 (64.4%) subjects. Among pMDI users, correct inhaler use was observed in only 26/73 (35.6%) of the patients, with lack of coordination between inhalation and generation of the aerosol and failure to breathe out gently before using the inhaler, being the most common errors. Among DPI users, 21 (51.2%) demonstrated correct inhaler use, with failure to perform a breath-hold for 10 seconds after inhaling the powder and to exhale gently before using the inhaler being the most common errors. Significant associations between inhaler technique and patient's understanding of asthma medications and the kind of follow-up clinic (respiratory versus nonrespiratory clinic) were found. No significant associations between inhaler technique and various maternal and fetal outcomes or asthma control were found. In conclusion, improper inhalation technique is significantly prevalent in pregnant asthmatic women, particularly among those being followed in nonspecialized respiratory clinics. The lack of significant association between the inhaler technique and asthma control (and hence maternal and fetal outcomes) may simply reflect the high prevalence of uncontrolled asthma and significant contribution of other barriers to poor asthma control in the current patient's cohort. Multidisciplinary management of asthma during pregnancy with particular emphasis on patient's education is imperative.

Recent advances and controversies in adult cardiopulmonary resuscitation.

Since its introduction more than four and half decades ago, the science of cardiopulmonary resuscitation has been enriched with a significant amount of scientific evidence. This in turn has led to the birth of new evidence based guidelines for resuscitation published by the European Resuscitation Council and the American Heart Association in late 2005. This article aims to review the recent advances and controversies in the science of resuscitation.

Paradoxical vocal cord motion disorder: past, present and future.

Paradoxical vocal cord motion disorder (PVCM), also called vocal cord dysfunction, is an important differential diagnosis for asthma. The disorder is often misdiagnosed as asthma leading to unnecessary drug use, very high medical utilisation and occasionally tracheal intubation or tracheostomy. Laryngoscopy is the gold standard for diagnosis of PVCM. Speech therapy and psychotherapy are considered the cornerstone of management of this disorder. The aim of this article is to increase the awareness of PVCM among doctors, highlighting the main characteristics that distinguish it from asthma and discuss the recent medical achievements and the possible future perspectives related to this disorder.

Primary Pituitary Tuberculosis Revisited.

BACKGROUND Primary pituitary tuberculosis (in absence of other organ involvement and constitutional symptoms) is an extremely rare disease with total reported cases in the literature fewer than a hundred. Misdiagnosis as pituitary adenoma is common and late diagnosis can result in a permanent endocrine dysfunction and/or long-term neurologic sequelae. CASE REPORT We report on the case of a middle-aged woman who presented with severe headache and left third cranial nerve palsy. Magnetic resonance imaging (MRI) revealed a large pituitary tumor invading the left cavernous sinus. The case was initially misdiagnosed as pituitary adenoma. A pituitary biopsy was performed and was suggestive of pituitary tuberculosis. Extensive radiologic investigations did not reveal any evidence of other organ involvement by tuberculosis. She was successfully treated with anti-tuberculous medications. CONCLUSIONS In areas with a high pre-test probability of tuberculosis, pituitary tuberculosis should be included in the differential diagnosis of pituitary tumors in order to avoid unnecessary surgical interventions. Besides being the first histologically-proven primary pituitary tuberculosis case reported from Qatar, the current case is unique in that extensive radiologic investigations did not reveal any evidence of other systemic or pulmonary tuberculosis.
