Gonococcal Infective Endocarditis Returns

Disseminated gonococcal infection occurs in 0.5%-3% of gonorrhea cases, usually in the form of either a triad of arthralgia, tenosynovitis, and skin lesions or purulent arthritis. Other rare complications include gonococcal infective endocarditis that occurs in 1%-2% of cases with 99 cases reported in the literature since 1938. Our case presents an additional rare case of aortic valve gonococcal endocarditis requiring surgical intervention and a prolonged antibiotic course, despite the absence of genitourinary symptoms or mucosal evidence of infection. This case was found to have sepsis and gonococcal endocarditis, which was clearly confirmed with positive blood cultures and aortic valve vegetation. It was further complicated by the evidence of splenic embolization and severe aortic regurgitation requiring surgical valve replacement and debridement of an annular perivalvular abscess. A high degree of suspicion is needed to early diagnose these unusual cases of gonococcal endocarditis, especially in sexually active individuals, for its known virulence causing valve destruction and high mortality. Our case represents a valuable addition to the reported cases of this diagnosis and is complemented by a short literature review.

Gemella morbillorum- and Capnocytophaga sp.-Related Mycotic Thoracic Aortic Aneurysm and Mediastinal Abscess: An Unusual Case Report, a Treatment Challenge, and a Review of Literature

A thoracic mycotic aortic aneurysm is an uncommon entity that can complicate mediastinal abscesses. Gemella morbillorum and Capnocytophaga sp. are oral bacteria that are very rarely encountered in this setting, especially when occurring together and with other organisms, posing a difficult treatment challenge per the available guidelines and sensitivities. We present in detail this interesting case of a multi-organism mediastinal abscess and thoracic mycotic aortic aneurysm after a previous esophagogastroduodenoscopic procedure in a 51-year-old female with known achalasia who presented with upper abdominal pain, including a successful surgical and antibiotic treatment regimen and a literature review of the involved topics.

To Lumbar Puncture or Not to Lumbar Puncture: A Case of Lyme Neuroborreliosis

Lyme disease is a zoonotic infection increasing in prevalence across the United States. While the recognition of its classic clinical signs is sufficient to establish the diagnosis in the early stages, the diagnosis of Lyme neuroborreliosis (LNB) may be challenging and the diagnostic approaches may have to be tailored. We report a rare case of early disseminated LNB presenting with features of Banwarth syndrome in the form of painful radiculoneuritis, motor weakness, and facial palsy in a middle-aged female who presented to an Upstate New York Hospital during summer. Lyme antibody testing was found to be positive at a level of 11.70 by enzyme immunoassay and Western Blot was IgM positive with three out of three reactive borrelial proteins. Lumbar puncture was not performed per the patient's preference. Otherwise, the laboratory workup along with MRI of the brain and cervical spine were grossly unremarkable. The patient was treated with a four-week course of oral doxycycline with resolution of all her symptoms. The diagnostic value of lumbar puncture in certain presentations of LNB remains controversial and is further discussed in this review.

Association between family history and severity of coronary artery disease in a nationwide sample of patients with a first time myocardial infarction

 

Having an early family history of coronary artery disease (CAD) is strongly associated with incident cardio-vascular disease. In younger patients with acute coronary syndrome, an association between family history and the severity of CAD, determined by the number of affected coronary arteries diagnosed through coronary angiography, has been reported. However, it is unknown if these findings apply to unselected patients with a first-time myocardial infarction (MI) and whether an early family history of other atherosclerotic cardiovascular diseases (ASCVD) affect CAD severity. Therefore, our objective was to investigate the association between a family history of ASCVD and the extent of CAD determined by coronary angiography findings in a large nationwide sample of patients with a first-time MI.

Material and methods

This study included a consecutive sample of 22,686 one-year survivors of first-ever MI aged, 18 to 76 years, identified in the national register SWEDEHEART. Attending the standardized 1-year revisit after MI, from 2006 through 2013. First-degree relatives, defined as parents and full siblings, were identified in the Swedish Multi-Generation Register and data on historical hospitalisations and deaths were extracted. The exposure was defined as having a first-degree relative with records of early ASCVD, defined as a register-verified hospitalisation due to myocardial infarction, any angina with coronary revascularization, stroke or cardiovascular death before the age of 55 in male or 65 years in female relatives. The primary outcome was severity of CAD categorized to four groups: zero-, single-, two- or three-vessel disease as registered in SWEDE-HEART. Left main stem disease was included in the three-vessel category. The distribution of the CAD severity categories was compared between those with and without an early family history of ASCVD using multinomial logistic regression, adjusted for age and sex and using single-vessel disease as the reference group.

Results

We included 22 686 participants (median age 63 [IQR 57–68] years; 27% women), of which 1450 had a family history of early ASCVD. A total of 2134 patients did not have any significant obstructive findings at the first coronary angiography, 10 951 patients had single-vessel disease, 5516 patients had two-vessel disease and 3970 patients had three-vessel or main stem disease. Both two-vessel disease (RRR 1.31, 95% CI 1.14–1.50) and three vessel and/or left main stem disease (RRR 1.29, 95% CI 1.1–1.51) were more common in patients with early family history of ASCVD when adjusting for age and sex, whereas no significant angiographic disease was less common (RRR 0.76, 95% 0.61–0.95).

Conclusion

Patients with a first-time MI and a family history of early ASCVD have an approximately 30% higher risk of advanced coronary artery disease, with more than two affected coronary vessels or left main stem disease.

An Unusual Case of the "Terrible Triad" in a Transgender Woman

With the increasing use of sodium-glucose cotransporter-2 inhibitors for type 2 diabetes and heart failure, clinicians need to understand how to treat euglycemic diabetic ketoacidosis (DKA), which is a potential side effect of the medication. The disease triad of euglycemic ketoacidosis, acute pancreatitis, and hypertriglyceridemia (HTG) has complex pathogenesis, and often the trigger of the triad is unknown. Here, we present an unusual case of euglycemic DKA in a transitioning transgender woman on canagliflozin who was treated with 10% dextrose and insulin infusions and apheresis. What makes our case unique is an added layer of complexity with her use of estrogen supplements contributing to HTG and gallstone formation, which could have set off the disease triad.

Investigating the need for therapeutic drug monitoring of imipenem in critically ill patients: Are we getting it right?

BACKGROUND

The drug levels and clearances of imipenem in critically ill patients are not comprehensively described in current literature, yet it is vital that adequate levels be achieved for therapeutic success.

OBJECTIVES

To determine the proportion of critically ill patients treated with imipenem/cilastatin with sub-therapeutic imipenem plasma levels, and to compare the clinical outcomes of those patients with therapeutic levels with those who had sub-therapeutic levels.

METHODS

Trough imipenem plasma levels of 68 critically ill patients from a surgical intensive care unit were measured using a validated high-performance liquid chromatography method. Imipenem trough levels were compared with the minimum inhibitory concentration (MIC) of the causative bacterial agents, based on a target value of 100% time above MIC (¦T >MIC).

RESULTS

The proportion of participants with sub-therapeutic imipenem levels was 22% (95% confidence interval (CI) 13% - 34%). The 14- and 28-day mortality rates in the sub-therapeutic group were 33% and 40%, respectively, compared with 19% (p=0.293) and 26% (p=0.346), respectively, in the therapeutic group. Sub-therapeutic imipenem plasma levels are associated with adjusted hazard ratio of 1.47 (95% CI 0.55 - 3.91).

CONCLUSIONS

The lower proportion of critically ill patients with sub-therapeutic imipenem plasma levels in this study compared with previous studies may be attributed to the practice of higher dosages and the administration method of extended infusions of imipenem/cilastatin in our setting. The results demonstrate a trend of higher mortality in patients with sub-therapeutic imipenem levels, although the results were not statistically significant at this sample size.

THE VALUE OF A REGIONAL 'LIVING' COVID-19 REGISTRY AND THE CHALLENGES OF KEEPING IT ALIVE

BACKGROUND

The availability of accurate, reliable, and timely clinical data is crucial for clinicians, researchers, and policymakers so that they can respond effectively to emerging public health threats. This was typified by the recent SARS-CoV-2 pandemic and the critical knowledge and data gaps associated with novel Coronavirus 2019 disease (COVID-19).We sought to create an adaptive, living data mart containing detailed clinical, epidemiologic, and outcome data from COVID-19 patients in our healthcare system. If successful, the approach could then be used for any future outbreak or disease.

METHODS

From 3/13/2020 onward, demographics, comorbidities, outpatient medications, along with 75 laboratory, 2 imaging, 19 therapeutic, and 4 outcome-related parameters, were manually extracted from the electronic medical record (EMR) of SARS-CoV-2 positive patients. These parameters were entered on a registry featuring calculation, graphing tools, pivot tables, and a macro programming language. Initially, two internal medicine residents populated the database, then professional data abstractors populated the registry. Clinical parameters were developed with input from infectious diseases and critical care physicians and using a modified COVID-19 worksheet from the U.S. Centers for Disease Control and Prevention (CDC). Registry contents were migrated to a browser-based, metadata-driven electronic data capture software platform. Eventually, we developed queries and used various business intelligence (BI) tools which enabled us to semi-automate data ingestion of 147 clinical and outcome parameters from the EMR, via a large U.S. hospital-based, service-level, all-payer database. Statistics were performed in R and Minitab.

RESULTS

From March 13, 2020 to May 17, 2021, 549,691 SARS-CoV-2 test results on 236,144 distinct patients, along with location, admission status, and other epidemiologic details are stored on the cloud-based BI platform. From March 2020 until May 2021, extraction of clinical-epidemiologic parameter had to be performed manually. Of those, 543 have had >/=75 parameters fully entered in the registry. Ten clinical characteristics were significantly associated with the need for hospital admission. Only one characteristic was associated with a need for ICU admission. Use of supplemental oxygen, vasopressors and outpatient statin were associated with increased mortality.Initially, 0.5hrs -1.5 hours per patient chart (approximately 450-575 person hours) were required to manually extract the parameters and populate the registry. As of May 17, 2021, semi-automated data ingestion from the U.S. hospital all-payer database, employing user-defined queries, was implemented. That process can ingest and populate the registry with 147 clinical, epidemiologic, and outcome parameters at a rate of 2 hours per 100 patient charts.

CONCLUSION

A living COVID-19 registry represents a mechanism to facilitate optimal sharing of data between providers, consumers, health information networks, and health plans through technology-enabled, secure-access electronic health information. Our approach also involves a diversity of new roles in the field, such as using residents, staff, and the quality department, in addition to professional data extractors and the health informatics team.Initially, due to the overwhelming number of infections that continues to accelerate, and the labor/time intense nature of the project, only a small fraction of all patients with COVID-19 had all parameters entered in the registry. Therefore, this report also offers lessons learned and discusses sustainability issues, should others wish to establish a registry. It also highlights the registry's local and broader public health significance. Beginning in June 2021, whole-genome sequencing results such as lineages harboring important viral mutations, or variants of concern will be linked to the clinical meta-data.

A Case of Failure of EkoSonic™ Endovascular System in the Treatment of Submassive Pulmonary Embolism

Submassive pulmonary embolism (SPE) is characterized by the presence of right ventricular (RV) strain as visualized on echocardiogram or CT scan with brain natriuretic peptide (BNP) and/or troponin elevation. The condition accounts for 20-25% of all pulmonary embolism (PE) cases. In cases of SPE, catheter-directed thrombolysis (CDT) is generally considered in the presence of severe hypoxemia, worsening RV dysfunction, patients with increasing tachycardia and elevated troponins, free-floating thrombus in the right atrium or RV, and presence of extensive clot burden. EkoSonic™ Endovascular System (EKOS; Boston Scientific, Marlborough, MA) has been successfully used to treat cases of PE even where systemic thrombolytic therapy has failed. However, in this article, we describe a unique case of the failure of EKOS in treating a 71-year-old African American man who presented to the hospital with progressively worsening chest pain, shortness of breath, and fatigue. He was suspected to have SPE; however, a CT pulmonary angiogram could not be performed to estimate the clot burden due to an acute kidney injury. He was diagnosed with coronavirus disease 2019 (COVID-19) pneumonia during the hospitalization and had a delayed EKOS procedure with minimal improvement in oxygenation and clot burden. He subsequently underwent half-dose systemic thrombolytic therapy with complete resolution of his symptoms. Given our success with half-dose systemic therapy, we propose that it may be considered as a "rescue therapy" in cases where EKOS fails to deliver results.

Standardized delivery room management for neonates with a prenatal diagnosis of congenital heart disease: A model for improving interdisciplinary delivery room care

Precise characterization of cardiac anatomy and physiology through fetal echocardiography can predict early postnatal clinical course. Some neonates with prenatally defined critical congenital heart disease have anticipated precipitous compromise during perinatal transition for which specialized, diagnosis-specific delivery room care can be arranged to expeditiously stabilize cardiopulmonary hemodynamics. In this article, we describe our institutional approach to the delivery room care of neonates with prenatally diagnosed congenital heart disease, emphasizing our diagnosis-specific care pathways for newborns with critical disease.

Amisulpride-induced agranulocytosis: A case report

Introduction

Agranulocytosis is a potentially life-threatening haematological side effect induced by typical and atypical neuroleptic. When agranulocytosis is associated with a specific anti-psychotic, the medication should be discontinued. This severe side effect is troublesome.

Case report

We report the case of a 60-year-old man, treated with amisulpride for schizophrenia, who developed an agranulocytosis. This patient had been treated with first and second generation anti-psychotic drugs during his life and had already been exposed to many neuroleptics without any signs of toxicity. However, after three days of the introduction of amisulpride he presented a rapid onset agranulocytosis (leukocytes 1.2 G/L and neutrophils 0.4 G/L). After discontinuation of amisulpride, blood count returned to normal. The favorable evolution after discontinuation of treatment: the normality of biological and cytological examinations is in favor of a causal relationship between this severe neutropenia al introduction of amisulpride.

Conclusion

This case report highlights the risk of amisulpride in inducing agranulocytosis, a risk underestimated in regard of the clozapine risk to induce agranulocytosis or neutropenia. For this reason, it seems reasonable to recommend performing a blood count before introduction and during the treatment by anti-psychotics.

A DFT study of Janus structure of S and Se in HfSSe layered as a promising candidate for electronic devices

The transition-metal dichalcogenides are presently being intensively researched because of their unique optoelectronic properties. Further, the success of TMDs in all areas of science without exception has opened the street to find other two-dimensional materials. Based on density functional theory, we study the vibrational and electronic properties of the mixed-phase of S and Se in HfSSe system, i.e, HfSSe monolayer and HfSSe/HfSSe bilayer. In this framework, our systems are full dynamically stable, which shown by their phonon dispersion. Also, we found that the HfSSe (heterolayer) monolayer is an indirect semiconductor (0.63 eV with BLYP), while the HfSSe (alternating) monolayer is a direct semiconductor (0.753 eV with BLYP). Our AA, AB, AA', and AB' of HfSSe/HfSSe (heterolayer) bilayer are indirect band gaps in a range 0.361-0.830 eV, which are promising candidates for electronic devices as field-effect transistors, photodetectors, and other optoelectronics. Nevertheless, HfSSe/HfSSe (alternating) bilayer is a direct bandgap semiconductor with a value of 0.671 eV, when vdW is used.

[An evolutionist approach of mood disorders from a transcultural perspective]

INTRODUCTION

The objective of this paper is to verify if traits and symptoms defined as pathological and maladjusted in certain contexts may produce adaptive effects in other contexts, especially if they occur in sub-threshold forms.

METHODS

A historical examination of how the symptoms of depression have changed in front of great social changes and an analysis of Sardinian migrants' thymic profiles toward several metropolises.

RESULTS AND CONCLUSIONS

Mood disorders have been increasing since the "English malady" in the 17th century, and we suppose that some forms of mood disorders might have an adaptive advantage. Otherwise, the increase of such an epidemic would have been self-limited. From a sociobiological point of view, it is highly probable that the environment of a rapidly evolving society can select people who are explorers and able to support accelerated biorhythms and that the condition of social change stimulates psychological and psychopathologic changes. It is also possible that hyperthymic persons modulate and create the new environment. If this model can explain the epidemic of mood disorders, its verification should guide future research.

Neuropathy by folic acid supplementation in a patient with anaemia and an untreated cobalamin deficiency: a case report

The rising rates of bariatric surgery (BS) are accompanied by neurological complications related to nutrient deficiencies. One of the risk factors for neurological complications in BS patients is poor vitamin and mineral supplementation. Prevention, diagnosis and treatment of these disorders are necessary parts of lifelong care after BS. Particularly important for optimal functioning of the nervous system are vitamin B₁ , B₆ , B₁₂ (cobalamin), E, copper and possibly vitamin B₁₁ (folic acid). In this case report, we narrate about a patient with anaemia and multiple vitamin and mineral deficiencies after Roux-en-Y gastric bypass (RYGB) with an alimentary limb of 150 cm and a biliopancreatic limb of 100 cm. RYGB is associated with an increased risk of vitamin deficiencies, especially a vitamin B₁₂ deficiency. The patient in this case report developed psychiatric-neurological symptoms due to folic acid supplementation in an untreated cobalamin deficiency. Second, we tried to elucidate the vitamin physiology to understand specific mechanisms after BS.

The adverse effects of interferon-free regimens in 149 816 chronic hepatitis C treated Egyptian patients

BACKGROUND

Interferon-free regimens are associated with high sustained virological response; however, associated adverse effects have yet to be fully reported.

AIM

To evaluate the adverse effects associated with the different direct-acting antiviral drug (DAA) regimens in Egyptian patients.

METHODS

This multicenter retrospective study included all adverse effects during and after treatment with DAA regimens of 149 816 chronic hepatitis C treated Egyptian patients. Patients received sofosbuvir (SOF)/ribavirin (RBV) (n = 21 835), SOF/simeprevir (n = 24 215) SOF/daclatasvir (DCV) (n = 58 477), SOF/DCV/RBV (n = 45 188) and paritaprevir/ombitasvir/ritonavir/RBV (n = 101). The duration of treatment varied between 12 and 24 weeks. All changes in the treatment regimens, discontinuation, mortality, and serious side effects were reported.

RESULTS

Adverse effects developed in 2475 (1.7%) (mean age [54 ± 9], male gender [53%]) patients. Serious side effects developed in 68% of these patients, and SOF/RBV was the most common causing regimen (73%, P < 0.001). Anaemia and hyperbilirubinemia were the most common side effects (731/149816, 0.5% and 463/149816, 0.3%, respectively) and SOF/RBV (588/21835, 3% and 353/21835, 1.6%, respectively) showed the highest incidence in the treated patients. Hepatocellular carcinoma and mortality were reported in 0.02% and 0.06% of all treated patients, respectively. Patients with liver cirrhosis showed higher incidence of serious side effects (Log rank P = 0.045) and mortality (Log rank P = 0.025) than patients without liver cirrhosis. Male gender (P = 0.012), lower haemoglobin (P < 0.001), platelets (P < 0.001) and albumin (P = 0.001), higher bilirubin (P = 0.002) and cirrhosis (P < 0.001) were factors associated with serious side effects development.

CONCLUSION

Adverse effects associated with DAAs are few, anaemia being the most common. SOF/RBV regimen showed the highest rate of side effects while SOF/DCV showed the least.

Lipoedema in patients after bariatric surgery: report of two cases and review of literature

Lipoedema is a disorder of adipose tissue that is characterized by abnormal subcutaneous fat deposition, leading to swelling and enlargement of the lower limbs as well as the trunk. This entity is often misdiagnosed as lymphoedema or obesity and, therefore, may be overlooked and missed in patients scheduled for bariatric surgery. Patients with lipoedema who undergo bariatric surgery may have to continue to have extensive lower extremity and trunk adiposity despite adequate weight loss. In this report, we present two patients who had extensive trunk and lower extremity adiposity, one of them before and the other after the bariatric surgery.

Local disease-ecosystem-livelihood dynamics: reflections from comparative case studies in Africa

This article explores the implications for human health of local interactions between disease, ecosystems and livelihoods. Five interdisciplinary case studies addressed zoonotic diseases in African settings: Rift Valley fever (RVF) in Kenya, human African trypanosomiasis in Zambia and Zimbabwe, Lassa fever in Sierra Leone and henipaviruses in Ghana. Each explored how ecological changes and human–ecosystem interactions affect pathogen dynamics and hence the likelihood of zoonotic spillover and transmission, and how socially differentiated peoples’ interactions with ecosystems and animals affect their exposure to disease. Cross-case analysis highlights how these dynamics vary by ecosystem type, across a range from humid forest to semi-arid savannah; the significance of interacting temporal and spatial scales; and the importance of mosaic and patch dynamics. Ecosystem interactions and services central to different people's livelihoods and well-being include pastoralism and agro-pastoralism, commercial and subsistence crop farming, hunting, collecting food, fuelwood and medicines, and cultural practices. There are synergies, but also tensions and trade-offs, between ecosystem changes that benefit livelihoods and affect disease. Understanding these can inform ‘One Health’ approaches towards managing ecosystems in ways that reduce disease risks and burdens.

This article is part of the themed issue ‘One Health for a changing world: zoonoses, ecosystems and human well-being’.

Generic daclatasvir plus sofosbuvir, with or without ribavirin, in treatment of chronic hepatitis C: real-world results from 18 378 patients in Egypt

BACKGROUND

Treatment of chronic hepatitis C using combination of sofosbuvir (SOF) and daclatasvir (DCV) was used in several clinical trials and multicentre studies, which were somewhat limited to genotypes 1-3. The national program in Egypt is using SOF-DCV combination for large scale treatment.

AIM

To assess the efficacy and safety of combined SOF-DCV in treating patients with HCV-G4 in a real-world setting.

METHODS

Data and outcome of chronic HCV patients who were treated for 12 weeks with generic medications: DCV 60 mg plus SOF 400 mg ± ribavirin (RBV) within the national hepatitis C treatment program in Egypt are presented. Treatment-naïve patients without cirrhosis were treated without RBV, and those who had cirrhosis or were treatment-experienced (interferon experienced or SOF experienced) received RBV. Efficacy and safety were assessed, and baseline factors associated with sustained virological response at post-treatment week 12 (SVR12) were explored.

RESULTS

During the first 2 months of the programme, 18 378 patients with HCV-G4 started treatment with SOF-DCV with or without RBV. Overall, 95.1% achieved SVR12 (95.4% among patients treated without RBV and 94.7% for patients treated with RBV, P = .32). Treatment was prematurely discontinued in only 1.5% of patients. The most common events leading to discontinuation were patient withdrawal (n = 76) and pregnancy (n = 5). Five deaths occurred within this group.

CONCLUSIONS

Real-world experience of generic SOF-DCV in patients with chronic HCV-G4 proved to be safe and associated with a high SVR12 rate, in patients with different stages of fibrosis.

Early effects of Epac depend on the fine-tuning of the sarcoplasmic reticulum Ca2+ handling in cardiomyocytes

In cardiac muscle, signaling through cAMP governs many fundamental cellular functions, including contractility, relaxation and automatism. cAMP cascade leads to the activation of the classic protein kinase A but also to the stimulation of the recently discovered exchange protein directly activated by cAMP (Epac). The role of Epac in the regulation of intracellular Ca²⁺ homeostasis and contractility in cardiac myocytes is still matter of debate. In this study we showed that the selective Epac activator, 8-(4-chloro-phenylthio)-2'-O-methyladenosine-3', 5'-cyclic monophosphate (8-CPT), produced a positive inotropic effect when adult rat cardiac myocytes were stabilized at low [Ca²⁺]_o (0.5mM), no changes at 1mM [Ca²⁺]_o and a negative inotropic effect when [Ca²⁺]_o was increased to 1.8mM. These effects were associated to parallel variations in sarcoplasmic reticulum (SR) Ca²⁺ content. At all [Ca²⁺]_o studied, 8-CPT induced an increase in Ca²⁺ spark frequency and enhanced CaMKII autophosphorylation and the CaMKII-dependent phosphorylation of SR proteins: phospholamban (PLN, at Thr17 site) and ryanodine receptor (RyR2, at Ser2814 site). We used transgenic mice lacking PLN CaMKII phosphorylation site (PLN-DM) and knock-in mice with an inactivated CaMKII site S2814 on RyR2 (RyR2-S2814A) to investigate the involvement of these processes in the effects of Epac stimulation. In PLN-DM mice, 8-CPT failed to induce the positive inotropic effect at low [Ca²⁺]_o and RyR2-S2814A mice showed no propensity to arrhythmic events when compared to wild type mice myocytes. We conclude that stimulation of Epac proteins could have either beneficial or deleterious effects depending on the steady-state Ca²⁺ levels at which the myocyte is functioning, favoring the prevailing mechanism of SR Ca²⁺ handling (uptake vs. leak) in the different situations.

Antipsychotic polypharmacy among schizophrenia outpatients

Introduction

Since their introduction by Delay and Deniker in the 1950s, neuroleptic drugs have significantly modified the evolutionary prognosis of schizophrenia. Their combination has also become a widespread practice.

Objectives

The aim of this study was to analyze the associations of neuroleptic drugs by describing the characteristics of types and doses, understanding the reasons for these associations and studying the relationship existing in such situation regarding adherence to treatment, tolerance and the number of hospitalizations.

Methods

Our study was retrospective, descriptive and analytical. It has been conducted from March, 1st to May, 30th 2015 and involved 70 stabilized patients diagnosed with schizophrenia according to DSM 5. Clinical characteristics were collected from patients and their medical records. Evaluations were conducted using PANSS, MARS and GAS.

Results

Overall, 70 male patients were recruited. The mean age was 40 years old: 30% received classical monotherapy while 70% were treated only by an atypical antipsychotic. Among patients receiving two drugs, 85% received classical bitherapy while 9% were under both classical and atypical drugs. Only 6% received atypical bitherapy. Chlorpromazine equivalent doses in case of monotherapy was 325.92 mg/day, while it reached 1148.65 mg/day in case of drugs association. Administration of a combined therapy had poor tolerance rate and all patients suffered from adverse effects. Adherence to treatment was better while receiving monotherapy (88% versus 45%) and the number of hospitalizations was lower with an average of 3 against 10.

Conclusion

Our study revealed several shortcomings in our current management of patients with schizophrenia and addressed the implication of socioeconomic status on therapeutic outcomes.

Sofosbuvir-based treatment regimens: real life results of 14 409 chronic HCV genotype 4 patients in Egypt

BACKGROUND

Chronic hepatitis C virus infection is one of the most important health problems in Egypt. The Ministry of Health's National Treatment Programme introduced sofosbuvir-based therapy in October 2014.

AIM

To assess the clinical effectiveness and predictors of response to SOF-based treatment regimens, either dual therapy, with SOF/ribavirin (RBV) for 6 months or triple therapy with SOF/peg-IFN-alfa-2a/RBV for 3 months, in a cohort of patients treated in National Treatment Programme affiliated centres in Egypt.

METHODS

Between October 2014 and end of 2014, patients who were eligible for treatment were classified according to their eligibility for interferon therapy: Group 1 (interferon eligible) were treated with triple therapy for 12 weeks and Group 2 (interferon ineligible) were treated with dual therapy for 24 weeks. Difficult to treat patients included those with F3-F4 on Metavir score, Fib-4 >3.25, albumin ≤3.5, total Bilirubin >1.2 mg/dL, INR >1.2 and platelet count <150 000 mm³ .

RESULTS

Twelve weeks post-treatment data were available on 14 409 patients; 8742 in group 1 and 5667 in group 2. In group 1, the sustained virological response at week 12 (SVR12) was 94% and in group 2 the SVR12 was 78.7%. Multivariate logistic regression analysis in which treatment failure is the dependent variable was done. Male gender, being a difficult to treat patient and previous interferon therapy were significant predictors of nonresponse in both treatment groups.

CONCLUSION

Results of sofosbuvir-based therapies in Egypt achieved similar rates of SVR12 as seen in phase III efficacy studies.

Effects of Irrigation and Rainfall on the Population Dynamics of Rift Valley Fever and Other Arbovirus Mosquito Vectors in the Epidemic-Prone Tana River County, Kenya

Rift Valley fever (RVF) is a mosquito-borne viral zoonosis that is found in most regions of sub-Saharan Africa, and it affects humans, livestock, and some wild ungulates. Outbreaks are precipitated by an abundance of mosquito vectors associated with heavy persistent rainfall with flooding. We determined the impact of flood-irrigation farming and the effect of environmental parameters on the ecology and densities of primary and secondary vectors of the RVF virus (RVFV) in an RVF-epidemic hotspot in the Tana River Basin, Kenya. Mosquito sampling was conducted in farms and villages (settlements) in an irrigated and a neighboring nonirrigated site (Murukani). Overall, a significantly higher number of mosquitoes were collected in farms in the irrigation scheme compared with villages in the same area (P < 0.001), or farms (P < 0.001), and villages (P = 0.03) in Murukani. In particular, key primary vectors of RVFV, Aedes mcintoshi Marks and Aedes ochraceous Theobald, were more prevalent in the farms compared with villages in the irrigation scheme (P = 0.001) both during the dry and the wet seasons. Similarly, there was a greater abundance of secondary vectors, particularly Culex univittatus Theobald and Culex pipiens (L.) in the irrigation scheme than in the Murukani area. Rainfall and humidity were positively correlated with mosquito densities, particularly the primary vectors. Adult floodwater mosquitoes and Mansonia spp. were collected indoors; immatures of Ae. mcintoshi and secondary vectors were collected in the irrigation drainage canals, whereas those of Ae. ochraceous and Aedes sudanensis Theobald were missing from these water bodies. In conclusion, irrigation in RVF endemic areas provides conducive resting and breeding conditions for vectors of RVFV and other endemic arboviruses.

Comparison Between Different Intramuscular Vitamin B12 Supplementation Regimes: a Retrospective Matched Cohort Study

BACKGROUND

The incidence of vitamin B₁₂ deficiency after bariatric surgery can range from 26 to 70 %. There is no consensus on optimal vitamin B₁₂ supplementation in postbariatric patients. The objective of this study was to compare three different regimes.

METHODS

In this retrospective matched cohort study, we included 63 patients with methylmalonic acid (MMA) levels ≥300 nmol/L. Group A (n = 21) received 6 intramuscular (im) vitamin B₁₂ injections including a loading dose, group B (n = 21) received 3 im vitamin B₁₂ injections without loading dose and group C (n = 21) received no im vitamin B₁₂ injections.

RESULTS

The total post-bariatric patient population consisted of 14 males (22.2 %) and 49 women (77.8 %) with a mean current body mass index of 30.6 ± 8.0 kg/m². There was no significant difference in vitamin B₁₂ and MMA levels between 3 groups at baseline. There was a significant difference in follow-up vitamin B₁₂ levels of group A compared to group B (p = 0.02) and group A compared to group C (p = 0.03). In the follow-up results, there is also a significant decrease in MMA levels of group A compared to group B (p = 0.02), group A compared to group C (p < 0.001), and group B compared to group C (p < 0.01).

CONCLUSIONS

In this study, a shorter injection regime is probably not sufficient to treat a vitamin B₁₂ deficiency. An injection regime with 6 injections recovered all vitamin B₁₂ deficiencies biochemically. MMA levels cannot recover spontaneously over time without additional im injection regime.

Antipsychotics-induced leukopenia and neutropenia: A case report and review of literature

Introduction

Antipsychotic drugs effectively control psychotic symptoms, but may cause important side effects, significantly increasing morbidity and mortality. Hematologic abnormalities are frequent and may be life-threatening in some patients. Many prospective investigations confirmed neutropenia as a frequent occurrence with virtually all atypical antipsychotics.

Objective and methods

Define epidemiological, clinical and therapeutic characteristics of antipsychotics – induced leukopenia and neutropenia through a case report and a review of literature.

Case report

Patient 28 years old native of Tunis, with family history: brother who suffer of undifferentiated schizophrenia. Since the age of 16 years he has been followed for disorganized schizophrenia (DSM IV). He was initially put under Haldol Decanoate (2 months), fluphenazine (2 months), amisulpride (3 months), sulpride (2 months), olanzapine (3 months), Rispreridone (1 month), aripiprazole (5 months) leukopenia/neutropenia is occurring during treatment with each molecule and which promptly resolved after discontinuation. Reduced white blood cell count has also been reported after addition of lithium. Actually an ECT is proposed for this patient.

Conclusion

This case report shows the importance of hematological monitoring during the course of typical or atypical treatment.

Affective disorders in multiple sclerosis

Background

Psychiatric disorders have a remarquable frequency in multiple sclerosis. The leading group of these disorders consists of affective disorders. These psychiatric conditions can worsen the outcome of multiple sclerosis, thus contributing to increase the burden of the disease to both patients and relatives. Managing such a complicated situation needs a focus on the underlying links between affective disorders and multiple sclerosis.

Objective

To examine the hypotheses proposed to explain the high prevalence of affective disorders in patients with multiple sclerosis.

Methods

Literature was reviewed using the Medline database and the following keywords “bipolar disorder” “affective disorder”, “mania” and “multiple sclerosis”.

Results

PubMed research returned 13 results. After manual inspection, 10 articles were retained and examined. The cause of the high comorbidity between multiple sclerosis and mood disorders is regarded as being multifactorial: the medication used in multiple sclerosis possibly inducing/exacerbating mood disturbances, the demyelinazing brain lesions which could bring about depression or mania, genetic overlapping with affective disorders and last the psychological reactions and adjustment difficulties to the neurological handicap.

Conclusion

Despite the fact that the higher prevalence of affective disorders in multiple sclerosis is well established, these disorders still remain underdiagnosed and undertreated. A shift towards a better assessment of the psychiatric comorbidity in multiple sclerosis patients and the optimal treatment of those disorders is fundamental.

Body dysmorphic disorder and psychosis: A case report and review of literature

Introduction

Patients with body dysmorphic disorder (BDD) are concerned about a slight or non-existent defect on their appearance, causing significant stress and interfering on their social and professional life.

Despite its prevalence and psychosocial impact, this disorder remains unknown by many clinicians.

Methods and objective

Through a review of literature and illustration in our case report we will define: the symptomatology of this pathology, psychopathological models of the disorder and the etiopathogenic assumptions associated with it, in terms of risk factors and neurobiological correlations.

Case report

Patient 33 years old unmarried having been the victim of an AVP at the age of 25 years causing him a head injury above right eye for which he undergoes cosmetic surgery three times but the patient still not satisfied with installation of psychotic and delusional disorders requiring the use of antipsychotics.

Conclusion

The complexity of body dysmorphic disorder should not discourage clinicians to confront this disease. The management requires more than putting under medical treatment associated to psychotherapy, we also need a good relationship of trust and maintain effective working alliance.

Short and long-term outcomes of systemic drainage to IVC: a new technique for pancreas transplantation

Ninety-eight percent of the whole pancreas does not serve the purpose of pancreatic transplantation and it is a major cause of surgical complications. Up to 30% of pancreas transplant recipients experience surgical complications and require reoperation. Graft thrombosis and pancreatitis are the most common complications of pancreas transplantation (PT). Thus, different surgical techniques have been described to overcome the surgical hurdles and reduce surgical complications. In this study, for the first time, we report short- and long-term outcomes of PT with inferior vena cava (IVC) venous drainage. Forty-five PTs (22 simultaneous pancreas and kidney [SPK] transplantations and 23 pancreas after kidney [PAK] transplantations) were performed with this technique in our center. Sixty-eight percent of the donors were imported from outside of our area after they were declined by their local transplantation center. Patient and graft survival rates were 100% at 1 year. No graft thrombosis or pancreatitis occurred with this technique. Six patients (13.3%) required reoperation (3 bleeding, 2 anastomotic leak, and 1 small bowel perforation). No patient or graft loss occurred due to surgical complications. We conclude that this technique provides fast and easy dissection of the venous drainage of the PT without the need of complete occlusion of venous outflow. Surgical complication rates were lower with this technique compared with other reported techniques.
