A Case of Myxedema Coma and Adrenal Insufficiency Post Pembrolizumab.

Background: Despite their important clinical benefits, immune checkpoint inhibitors (ICIs) are associated with a spectrum of side effects known as immune-related adverse events (irAEs). These can be of various organ system backgrounds, including dermatologic, pulmonary, gastrointestinal, and endocrine. Polyglandular endocrinopathies (PLEs) post-ICIs therapy has been reported in the literature; however, to our knowledge, only a few have been documented with pembrolizumab. Case Report. We present a case of a female patient who developed myxedema coma (MC) and adrenal insufficiency (AI) after 4 months of stopping pembrolizumab, a programed-cell death-1 inhibitor. The patient was clinically symptomatic and was subsequently treated with levothyroxine and hydrocortisone. Discussion. It is very important to be vigilant and alert in detecting MC and AI to avoid any mortality. Pembrolizumab's effect on inducing antitumor responses leads to a wide variety of multiorgan alterations. Its role in raising the risk of all-grade endocrine disorders has been previously highlighted along with thyroidal dysfunctions. Our patient's presentation falls within the literature-based median time for hypothyroidism and AI with respect to the period from the initiation of pembrolizumab. The patient's predisposition to hypothyroidism and the likelihood of intertwined manifestations of AI and hypothyroidism should always be considered in the setting of critical illness. Conclusion: It is of high significance to explore the mechanism of action of ICIs and their side effects. PLEs can house some endocrinologic emergencies that are life threatening.

Lower odds of COVID-19-related mortality in hospitalised patients with type II diabetes mellitus: A single-centre study.

BACKGROUND: COVID-19 infection in patients with type 2 diabetes mellitus (T2DM) -a chronic illness in Lebanon-is not well described. METHODS: This was a single-centre retrospective observational study of 491 patients, including 152 patients with T2DM, who were hospitalised for COVID-19 between 20 August 2020 and 21 April 2021. Data on clinical characteristics, laboratory and radiological findings and outcomes were collected from the electronic medical records. Clinical characteristics and in-hospital mortality between patients with and without T2DM infected with COVID-19 using multivariate analysis were compared. RESULTS: Patients with T2DM were significantly older than those without T2DM (mean age, 68.7 vs. 60.3 years). Patients with T2DM were more likely to present with a body temperature of <38.3°C (83.9% vs. 69.9%) and less likely to present with chest pain (3.9% vs. 9.1%) and sore throat (2.0% vs. 6.8%). Patients with T2DM were more likely to be hypertensive (76.35% vs. 41%) and dyslipidaemic (58.6% vs. 25.7%) and had more frequent underlying coronary artery disease (33.6% vs. 12.4%). The rates of patients with creatinine levels of ≥1.17 mg/L and troponin T levels of ≥4 ng/dL were higher in the T2DM group than in the non-T2DM group (30.4% vs. 15% and 93.3% vs. 83.1%, respectively). Patients with T2DM were more likely to be admitted to the intensive care unit (ICU) (34.2% vs. 22.1%), require invasive ventilation (18.4% vs. 10.3%) and receive vasopressors (16.4% vs. 10.0%). Increasing age and the use of invasive ventilation and vasopressors were associated with higher odds of mortality (odds ratio (OR), 1.08, 9.95 and 19.83, respectively), whereas longer ICU stay was associated with lower odds of mortality (OR, 0.38). The odds of mortality were lower in the T2DM group than in the non-T2DM group (OR, 0.27). CONCLUSION: Among patients hospitalised for COVID-19, those with T2DM were older, presented with milder symptoms and had more comorbidities and higher troponin T levels compared with those without T2DM. Despite the worse clinical course, the patients with T2DM had lower odds of mortality than those without T2DM.

Diabetes Mellitus across the Arabo-Islamic World: A Revolution.

Background: Mankind continues to suffer from the ever-growing diabetes epidemic and the rapid rise of type 2 diabetes mellitus (T2DM). This metabolic disease has been studied since ancient civilizations. The Arabo-Islamic civilization excelled in establishing some of the most notable discoveries and teachings that remained the blueprint for years to come in the field of diabetology. Aim: This article aimed to review the ancient history of diabetes mellitus, with its main focus on the Arabo-Islamic civilization, and to report our subjective views and analysis of some of the past recommendations based on modern-day findings. Discussion. It is natural to have the teachings of medicine dynamically inspired by one civilization to another, as various fields continue to expand and evolve. This also applies to diabetology as the Arabo-Islamic world used the outlines of prior civilizations to revolutionize the understanding of the disease. Al-Razi and Ibn Sina are probably two of the most renowned polymaths in history, and their contributions to diabetology are well documented. Ibn Maymun's postulation about the higher prevalence of diabetes in Egypt as compared to Andalusia is something to be carefully studied. It could be that diabetes mellitus' underdiagnosis and late-stage detection are some of the major reasons for the disparity between the two mentioned regions. Modern-day Arabo-Islamic scholars continue to excel in revolutionizing diabetology. Conclusion: The Arabo-Islamic world houses an impressive bout of scholars who have contributed since the ancient times to diabetology. This scientific locomotion shows no signs of stopping, as it continues to shine during the present day, and likely in the future.

A Rare Presentation of Intrasellar Mucocele Post-transsphenoidal Resection of a Non-secreting Pituitary Macroadenoma.

An enlarging sphenoid sinus mucocele can facilitate the growth of an intrasellar sinus mucocele. This subsequently leads to pituitary gland compression and endocrine abnormalities. We report the case of a 54-year-old man who underwent transsphenoidal resection of a non-secreting pituitary macroadenoma. Twenty years later he presented with headache, visual disturbances, erectile dysfunction, and poor libido and was diagnosed with a large sphenoid sinus mucocele that consequently extended into the sellar region. Based on the literature review, isolated intrasellar sinus mucocele post-transsphenoidal endoscopic surgery has been reported once. This is the first case of an intrasellar mucocele post-transsphenoidal resection to present with endocrine compromise on top of the compressive pituitary stalk symptoms.

Evolution of COVID-19 infection characteristics in a Lebanese cohort of inpatients during different pandemic periods.

This study aims to describe COVID-19 patients characteristics, laboratory and imaging results, and the different outcomes of patients admitted to the Lebanese American University Medical Center-Rizk Hospital over a period of 9 months. In this observational retrospective study, data were obtained from electronic medical records of 491 male and female patients from the ages of 17 to 97. Analysis of the patients was performed in 3 periods: August 2020 to October 20 November 202020 to January 2021 and February 2021 to April 2021 corresponding with 3 waves of newly diagnosed cases during this period. The sample showed a male predominance with an average age of 63. The average hospitalization length was 10.1 days. The majority of patients were discharged to quarantine. The distribution of hospitalized cases was significantly correlated to the monthly distribution of newly COVID-19 cases in Lebanon. There was no significant difference in patient's characteristics between the 3 periods of the study (gender, age, body mass index, smoking, and medical conditions). Clinical presentations of the patients varied between the 3 periods. Similarly, the course and outcome of infection varied. Patients received less oxygen during period 1, while more patients were cured during period 3. This study presents the first Lebanese cohort of COVID-19 patients with their medical background, clinical presentation, laboratory results, radiological findings and course of infection with its outcome. It also shows how the relations between the medical manifestation of the COVID-19 pandemic and the socio-political measures of infection control are deeply intertwined.

Effect of combination of prophylactic or therapeutic anticoagulation with aspirin on the outcomes of hospitalized COVID-19 patients: An observational retrospective study.

Regimens for managing thromboembolic complications of COVID-19 are still not very well established. The present study compares the clinical characteristics and outcomes of patients hospitalized with COVID-19 receiving different anticoagulation regimens with and without aspirin. This is a retrospective observational study of 491 patients hospitalized for COVID-19 from August 2020 to April 2021. Data regarding clinical characteristics, laboratory findings, and outcomes of patients receiving different anticoagulation with and without aspirin regimens was collected, according to which 5 patient groups were defined: received no anticoagulation (NAA), prophylactic anticoagulation with (PA) or without aspirin (PAA) and therapeutic anticoagulation with (TA) or without aspirin (TAA). The average age was highest in the TAA group. Desaturation was highest in the TA and TAA groups. Diabetes, hypertension, dyslipidemia and coronary artery disease were the most prevalent in aspirin groups (PAA and TAA) as was heart failure in the TA and TAA groups and cancer in the TA and PAA groups. Elevated troponin was observed in the PAA and TAA groups. TA and TAA patients received oxygen therapy, needed ICU admission overall, and required invasive ventilation and vasopressors the most. Prophylactic anticoagulation groups (PA and PAA) had the highest patient survival rates. Patients with severe COVID-19 infections were more likely to receive higher, therapeutic, anticoagulation doses. Aspirin was given to patients with preexisting comorbidities, but it had no statistically significant impact on the outcomes of the different groups. Groups receiving prophylactic anticoagulation had the best survival outcomes.

Cryptococcal meningitis post-covid-19 infection: Immunomodulation, a double-edged sword.

Cryptococcal meningitis is an opportunistic infection associated with altered immunity. Immunomodulatory agent use in severe coronavirus disease 2019 (COVID-19) may predispose such infections. Here, we present a 75-year-old male patient who presented with fever and altered general status after severe COVID-19 infection and developed cryptococcal meningitis. Opportunistic infection may arise from the use of immunomodulation in severe COVID-19, especially in the elderly population. This article describes the case and extensively reviews cryptococcal disease post-COVID-19 literature, highlighting the risk from immunosuppressive treatment.

Intravenous high dose vitamin C and selected antiviral drugs in hospitalized COVID-19 patients: a descriptive cohort study.

INTRODUCTION: There is lack of universal agreement on the management of COVID-19. Intravenous high dose vitamin C (HDVC), remdesivir (RDV), and favipiravir (FPV) have been suggested as part of the treatment regimens and only RDV is approved by the Food and Drug Administration (FDA) so far. There is no study in Lebanon that addresses the descriptive cohort of HDVC and antiviral therapy amongst COVID-19 inpatients. Our goal was to highlight such a cohort. METHODOLOGY: A retrospective electronic chart review of COVID-19 inpatients was done over a period of 10 months (August 2020 to April 2021). Comparative data analysis was performed between HDVC and non-HDVC (NHDVC) groups, and RDV and FPV groups. RESULTS: Among HDVC patients, 70.1% (p = 0.035) and 67.2% (p = 0.008) had dyspnea and desaturation respectively. Patients on HDVC were less likely to remain in hospital for more than 20 days (p = 0.003). HDVC patients were more likely to be on oxygen therapy with 74.7% (p = 0.002). RDV patients were more likely to be on other COVID-19-related medications during hospitalization including the use of tofacitinib, baricitinib, tocilizumab, and anticoagulation as recommended in the guidelines. Statistical significance was noted for the status on discharge as 90.1% of the patients that received RDV were discharged after clinical improvement, compared to the 74.2% of the FPV patients. CONCLUSIONS: Further research is needed to establish local guidelines for the treatment of COVID-19. A significant role of HDVC and FPV might resurface if randomized control trials are conducted.

Pseudotumor Cerebri Secondary to Jugular Bulb Thrombosis: A Case Report and a Review of the Diagnostic Steps.

Pseudotumor cerebri (PTC) secondary to cerebral venous sinus thrombosis can be a difficult diagnosis to make for various reasons, including an atypical patient profile and potentially pleomorphic signs and symptoms. The symptoms can be insidious and can evolve acutely, subacutely, or chronically. To complicate the picture even further, neurodiagnostic testing can be particularly troublesome due to both false-positive and false-negative results. Frequently, multiple imaging modalities are variably deployed, and they include computed tomography (CT) with and without contrast, computed tomography venogram (CTV), magnetic resonance imaging (MRI), and magnetic resonance venography (MRV) of the brain. The thrombus can be quite subtle, requiring the seasoned eye of an experienced neuroradiologist. Nevertheless, when a diagnosis is made, the treatment can be highly efficacious and gratifying as it can prevent serious visual complications. We present a rare case of PTC due to a jugular bulb thrombosis and outline the challenging diagnostic steps.

The Lebanese Healthcare Crisis: An Infinite Calamity.

In the past, a number of events rocked Lebanon, a small region of the previously prestigious Phoenician civilization. Whether it was mandates, wars, or economic compromises, the country always seemed to rise up again to a prominent stature in the Middle East. Once known as Switzerland of the East, Lebanon was torn apart by the works of sectarian battles during the civil war from 1975 to 1990. Since then, the country has never been the same with the turmoil left and right. Despite all of that, the healthcare sector has been one of the most prominent in the Middle East and the entire Arab world with accomplished physicians returning from immigration to serve their country. Lebanon excelled in holding first-time international conferences, performing medical interventions, and offering one of the best healthcare education and training to its juniors. The most recent setbacks since late 2019 have, however, held Lebanon back and subsequently handcuffed the healthcare system, leading to the impactful demise of the once glorious care. Nevertheless, the healthcare system remains one of the top-tier domains fighting against the coronavirus disease 2019 (COVID-19) pandemic and the failings of the rocked state.

Incidence of diabetes and its predictors in the Greater Beirut Area: a five-year longitudinal study.

BACKGROUND: Type 2 Diabetes (T2D) remains a world epidemic. Obtaining accurate estimates of its incidence and their predictors will aid in targeting preventive measures, allocating resources, and strategizing its management. The Middle East North Africa region has high T2D prevalence and rates of rise. Few incidence studies exist for the region, and none from Lebanon. The current study objective was to determine diabetes incidence and diabetes predictors in a community-based Lebanese sample. A secondary objective was to describe the metabolic control over time in adults with preexisting diabetes. METHODS: This is a five-year (2014-2019) follow-up study on a random sample of 501 residents of the Greater Beirut area. Out of 478 people eligible to participate in the follow-up study, 198 returned (response rate 39.5%). Assessment included medical history, anthropometric measures, food frequency, sleep, and lifestyle questionnaires. Laboratory data included glycemic indices (fasting glucose and HbA1C) and other biological markers. The diagnosis of probable diabetes (PD) was based on one abnormal test for either fasting glucose ≥ 126 mg/dL or HbA1C ≥ 6.5% or having history of diabetes. RESULTS: The incidence of diabetes was 17.2 (95% CI 9.6-28.7) per 1000 person-years. Cardiometabolic risk factors independently associated with diabetes were: older age, higher BMI, family history of diabetes, metabolic syndrome, higher CRP and triglyceride level; whereas an independent predictor of diabetes was previous BMI. In addition, the 42 participants with preexisting diabetes had worsening of their metabolic profile over a five-year period. CONCLUSIONS: The incidence of diabetes was high as compared to some reported world rates, and in line with the high prevalence in the MENA region. The risk was highest in those with positive family history and the presence of the metabolic syndrome or its components. Preventive measures should particularly target participants with that specific risk profile. This becomes particularly important when observing that metabolic control gets worse over time in individuals with diabetes.

The Spread of Plasmidic AmpC in a General Lebanese Hospital Over Nine Consecutive Years and the Relationship With Restricted Isolation Protocols.

Background: The dreaded bacterial infection by extended-spectrum ß-lactamases (ESBL)-producers has always troubled the medical field whether on the public, scientific, or clinical levels. One of the lesser known ß-lactamases, which is capable of hydrolyzing broad and extended-spectrum cephalosporins-i.e., cephamycins plus oxyimino-ß-lactams-are the AmpC ß-lactamases. This group, which has also been termed occasionally-and incorrectly-as ESBL Class C, confers resistance to ß-lactamase inhibitors. The prevalence of plasmidic AmpC (pAmpC) strains is possibly still a matter of debate considering the unevenly matched data between phenotypically-detected and molecularly-detected pAmpC. Aim: In the absence of any study in Lebanon addressing the AmpC, our intention was to determine the numbers and percentages of AmpC Enterobacteriaceae isolates, notably plasmid-mediated ones, across different wards at the Centre Hospitalier du Nord (CHN), Lebanon, and highlight the importance of infection control protocols. Materials and Methods: Carriage and infection with pAmpC Enterobacteriaceae were retrospectively investigated between 2011 and 2015 and prospectively between 2016 and 2019 at the Centre Hospitalier du Nord Hospital, North Lebanon. The rise or decline in the numbers of such strains, in concordance with the allegedly intensive isolation of the patients, were analyzed. Results: Intensive care unit (ICU) data shows an initial rise in infection isolates from 2012 to 2014 and in the carriage isolates from 2012 to 2013 with later notable overall decrease in the both isolates' numbers with the application of the isolation protocols at CHN from 2014 onwards. Floors 2, 3, and 4 seemed to house the bulk of the isolates as well. Conclusion: Preventive measures, such as on-going surveillance of the hospital wards by specialized healthcare personnel and strict implementation of infection control practices, should be a top priority in any medical center in order to isolate such strains and try to put a limit for the development and the dissemination of any possible multidrug resistant strains.

Fixed Drug Eruption Secondary to Four Anti-diabetic Medications: An Unusual Case of Polysensitivity.

We report a case of fixed drug eruption in a 58-year-old lady treated for diabetes with four pharmacologically different anti-diabetic agents that were used at separate times of therapy. Skin manifestations, including erythema, blisters, and ulcers, developed over the right leg each time after the initiation of metformin, gliclazide, vildagliptin, and empagliflozin; and disappeared following the discontinuation of the drugs. Magnesium stearate was the common excipient identified in the four agents. This is an extremely rare case of fixed drug eruption caused by structurally dissimilar drugs.

A case of massive saddle pulmonary embolism and benign tracheal stenosis in a patient with COVID-19 infection.

Since December 2019, the novel coronavirus disease 2019 (COVID-19) outbreak that started in Wuhan, China, has become a global pandemic affecting millions of people around the globe. These patients are prone to a number of complications either related to their disease or to the different treatment modalities. Pulmonary embolism (PE) and benign post-intubation tracheal stenosis (BTS) are among these complications. In this study, we report the case of a patient with a recent COVID-19 infection that got complicated by a massive PE as well as a BTS.
