Clinical, molecular, and drug resistance epidemiology of HIV in Jordan, 2019-2021: a national study

BACKGROUND

Limited epidemiologic studies have been conducted in Jordan describing the HIV epidemic. This study aimed to address this gap to inform HIV prevention and control.

METHODS

A nationally-representative cross-sectional study was conducted among adults living with HIV in Jordan. Laboratory testing included HIV viral load and next-generation-sequencing-based clinical genotype. Log-binomial regression estimated risk ratios (RRs) and 95% confidence intervals (CIs).

RESULTS

Among 231 (70%) participants, most were male (184/80%), and from Jordan (217/94%). Among 188 treatment-experienced-participants (>6 months), 165 (88%) were virally suppressed. High level resistance was most frequent against nucleoside reverse transcriptase inhibitor (13/81%), and integrase-strand transfer inhibitor (INSTI) (10/62%) drugs among viremic (≥1,000 HIV copies/mL) treatment-experienced participants with drug resistant mutations (DRMs, n=16). Common HIV subtypes (n=43) were B (6/14%), A1 (5/12%), and CRF01_AE (5/12%); additionally, novel recombinant forms were detected. In multivariate analysis, independently higher risk for late diagnosis (n=49) was observed with diagnosis through blood donation (vs check-up: RR 2·20, 95%CI 1·16-4·17) and earlier time-period of diagnosis (1986-2014 vs 2015-2021: RR 2·87, 95%CI 1·46-5·62).

CONCLUSIONS

Late diagnosis and INSTI resistance endanger national HIV prevention and treatment in Jordan - high-level resistance to INSTI suggests therapeutic drug monitoring is needed for treatment efficacy, and conservation of treatment options.

Prevalence and Associated Factors of Toenail Onychomycosis Among Patients with Diabetes in Jordan

BACKGROUND

Toenail onychomycosis is common in patients with diabetes and it can increase the risk of secondary infections and foot complications. Despite several studies investigating the prevalence and associated factors of toenail onychomycosis from different parts of the world, there are no data from Jordan.

OBJECTIVE

To determine the prevalence and the associated factors of toenail onychomycosis among patients with diabetes in Jordan.

METHODS

A cross-sectional study was conducted on 375 patients with diabetes at the National Centre for Diabetes, Endocrinology, and Genetics in Amman, Jordan. Several socio-demographic and health-independent variables including foot self-care practices were collected. Toenail onychomycosis was assessed by a specimen culture and microscopic examinations. Descriptive and inferential statistics were used for data analysis.

RESULTS

The prevalence of toenail onychomycosis was 57.6% (n=216). Multiple logistic regression revealed four significant associated factors; the presence of neuropathy (β=1.87, p=0.02), being an ex-smoker (β=2.69, p=0.01), being treated by both insulin and oral hypoglycemics drugs (β=1.32, p=0.03), and using antibiotics in the last year (β=1.78, p=0.02).

CONCLUSION

The prevalence of toenail onychomycosis among patients with diabetes in Jordan is high. Regular foot screening and podiatric care are recommended especially among patients with diabetic neuropathy, current treatment by insulin and oral hypoglycemics drugs, previous history of smoking, and previous use of antibiotics.

Percutaneous Partial Bone Excision in the Management of Diabetic Toe Osteomyelitis

BACKGROUND

Diabetic foot osteomyelitis affecting the toes is associated with several complications including amputation. Management is variable and include medical therapy alone or coupled with surgery. Removal of infected tissues is a common therapeutic option. However, limited source data are available. This study determines the outcome and complications of percutaneous partial bone excision (PPBE) of infected bone among diabetic patients with toe osteomyelitis.

METHODS

This is an uncontrolled experimental prospective study in diabetic patients who underwent PPBE of infected pieces of bone for toe osteomyelitis in the outpatient setting at a single foot clinic. All participants were followed up until the occurrence of wound healing or amputation.

RESULTS

Forty-seven patients (mean ± SD age was 62.8 ± 11.6 years) participated. Forty-four patients (93.6%) had complete healing and 3 (6.4%) required toe amputation. The mean (±SD) wound healing time was 11 (±4.6) (range, 7-22) weeks. Diabetes mellitus type 1 and younger age were significantly associated with increased risk for amputation.

CONCLUSION

PPBE of infected toes in diabetic patients can be performed successfully and safely in the outpatient clinic. It can also improve healing and avoids inpatient stay.

LEVEL OF EVIDENCE

Level II, prospective cohort study.

Assessing Healthcare Workers' Knowledge and Their Confidence in the Diagnosis and Management of Human Monkeypox: A Cross-Sectional Study in a Middle Eastern Country

The ongoing multi-country human monkeypox (HMPX) outbreak was declared as a public health emergency of international concern. Considering the key role of healthcare workers (HCWs) in mitigating the HMPX outbreak, we aimed to assess their level of knowledge and their confidence in diagnosis and management of the disease, besides the assessment of their attitude towards emerging virus infections from a conspiracy point of view. An online survey was distributed among HCWs in Jordan, a Middle Eastern country, during May−July 2022 using a questionnaire published in a previous study among university students in health schools in Jordan. The study sample comprised 606 HCWs, with about two-thirds being either physicians (n = 204, 33.7%) or nurses (n = 190, 31.4%). Four out of the 11 HMPX knowledge items had <50% correct responses with only 33.3% of the study respondents having previous knowledge that vaccination is available to prevent HMPX. A majority of study respondents (n = 356, 58.7%) strongly agreed, agreed or somewhat agreed that the spread of HMPX is related to a role of male homosexuals. Confidence in the ability of diagnosis based on the available monkeypox virus diagnostic tests was reported by 50.2% of the respondents, while the confidence levels were lower for the ability to manage (38.9%) and to diagnose (38.0%) HMPX cases based on their current level of knowledge and skills. Higher confidence levels for HMPX diagnosis and management were found among physicians compared to nurses. The endorsement of conspiracy beliefs about virus emergence was associated with lower HMPX knowledge, the belief in the role of male homosexuals in HMPX spread, and with lower diagnosis and management confidence levels. The current study highlighted the gaps in knowledge regarding HMPX among HCWs in Jordan as well as the lack of confidence to diagnose and manage cases among physicians and nurses. Raising the awareness about the disease is needed urgently considering the rapid escalation in the number of cases worldwide with reported cases in the Middle East. The attitude towards male homosexuals’ role in HMPX spread necessitates proper intervention measures to prevent stigma and discrimination among this risk group. The adoption of conspiratorial beliefs regarding virus emergence was widely prevalent and this issue needs to be addressed with proper and accurate knowledge considering its potential harmful impact.

Painful subacute thyroiditis occurring after the administration of influenza vaccine and hyaluronic acid dermal filler: A case report

RATIONALE

The occurrence of subacute thyroiditis (SAT) after vaccines or after hyaluronic acid skin fillers is very rare and might be related to genetic susceptibility. We suggest that the co-administration of both products could potentially increase the possibility of development of SAT.

PATIENT CONCERNS

A 58-year-old Caucasian healthy female initially presented with chills, myalgia, dysphagia, sore throat, dry cough, fatigue, and intermittent fever of 38.5°C orally after simultaneous injection of an influenza vaccine and a dermal filler containing hyaluronic acid. Ten days later the patient developed palpitations and neck pain radiating to the left jaw.

DIAGNOSIS AND INTERVENTIONS

She was diagnosed with SAT on day 16 after her first visit and responded promptly to etoricoxib treatment.

OUTCOMES

The patient progressed clinically from hyperthyroidism to euthyroid state and eventually to hypothyroidism and further testing showed she had HLA B-35 haplotype.

LESSONS

Physicians should be aware that SAT might be associated with the administration an influenza vaccine and this possible association might increase if the vaccine was co-administered with a dermal filler.

Tracking the Epidemiologic Shifts in Hepatitis A Sero-Prevalence Using Age Stratification: A Cross-Sectional Study at Jordan University Hospital

The study of hepatitis A virus (HAV) epidemiology and sero-prevalence has important public health implications. Changes in the epidemiology of hepatitis A can result in a larger pool of susceptible persons in countries with improved sanitation and hygienic conditions if vaccination is not provided. The aim of this study was to investigate the prevalence of HAV immunoglobulin G (IgG) in Jordan. In addition, we aimed to identify the potential differences in HAV sero-prevalence based on age, among other variables. We recruited the study participants at Jordan University Hospital in Amman, Jordan, during October 2020-June 2021. Assessment of participants' socio-demographic variables was done using a paper-based questionnaire. Testing for HAV IgG was based on a competitive enzyme linked immunosorbent assay (ELISA). The study population comprised 360 individuals with a median age of 18 years. The overall sero-prevalence of HAV in our study sample was 38.3%. Divided by age, the sero-prevalence of HAV was 8.2%, 12.3%, and 20.8% among individuals aged 10 years or less, 15 years or less, and 30 years or less, respectively. The estimated age at mid-population immunity was between 21 and 30 years. Besides age, individuals residing outside the Central region of Jordan had a significantly higher HAV sero-prevalence. Additionally, the use of filtered municipal water was associated with a lower sero-prevalence of HAV compared with the use of unfiltered municipal water among individuals aged 15 years or less. The results of this study suggest an intermediate to low endemicity of HAV in Jordan. An epidemiologic shift of HAV sero-prevalence with a declining rate of positivity for HAV IgG was noticed in this study. This highlights the importance of the recently introduced HAV vaccination in Jordan. Future research to evaluate the public health benefits of HAV vaccination in Jordan is recommended.

Low COVID-19 Vaccine Acceptance Is Correlated with Conspiracy Beliefs among University Students in Jordan

Vaccination to prevent coronavirus disease 2019 (COVID-19) emerged as a promising measure to overcome the negative consequences of the pandemic. Since university students could be considered a knowledgeable group, this study aimed to evaluate COVID-19 vaccine acceptance among this group in Jordan. Additionally, we aimed to examine the association between vaccine conspiracy beliefs and vaccine hesitancy. We used an online survey conducted in January 2021 with a chain-referral sampling approach. Conspiracy beliefs were evaluated using the validated Vaccine Conspiracy Belief Scale (VCBS), with higher scores implying embrace of conspiracies. A total of 1106 respondents completed the survey with female predominance (n = 802, 72.5%). The intention to get COVID-19 vaccines was low: 34.9% (yes) compared to 39.6% (no) and 25.5% (maybe). Higher rates of COVID-19 vaccine acceptance were seen among males (42.1%) and students at Health Schools (43.5%). A Low rate of influenza vaccine acceptance was seen as well (28.8%), in addition to 18.6% of respondents being anti-vaccination altogether. A significantly higher VCBS score was correlated with reluctance to get the vaccine (p < 0.001). Dependence on social media platforms was significantly associated with lower intention to get COVID-19 vaccines (19.8%) compared to dependence on medical doctors, scientists, and scientific journals (47.2%, p < 0.001). The results of this study showed the high prevalence of COVID-19 vaccine hesitancy and its association with conspiracy beliefs among university students in Jordan. The implementation of targeted actions to increase the awareness of such a group is highly recommended. This includes educational programs to dismantle vaccine conspiracy beliefs and awareness campaigns to build recognition of the safety and efficacy of COVID-19 vaccines.

High Rates of COVID-19 Vaccine Hesitancy and Its Association with Conspiracy Beliefs: A Study in Jordan and Kuwait among Other Arab Countries

Vaccination could be an effective strategy for slowing the spread of the current coronavirus disease 2019 (COVID-19) pandemic. Vaccine hesitancy could pose a serious problem for COVID-19 prevention, due to the spread of misinformation surrounding the ongoing pandemic. The aim of this study was to assess the attitudes towards the prospective COVID-19 vaccines among the general public in Jordan, Kuwait and other Arab countries. We also aimed to assess the association between COVID-19 vaccine acceptance and conspiracy beliefs. This study used an online survey distributed in December 2020, with items assessing conspiracies regarding COVID-19's origin and vaccination. Attitudes towards COVID-19 vaccines were assessed using the Vaccine Conspiracy Belief Scale (VCBS), with higher scores indicating a greater belief in vaccine conspiracy. A total of 3414 respondents completed the survey, the majority being residents of Jordan (n = 2173, 63.6%), Kuwait (n = 771, 22.6%) and Saudi Arabia (n = 154, 4.5%). The acceptance rates for COVID-19 and influenza vaccines were 29.4% and 30.9%, respectively. Males, respondents with higher educational levels and those with histories of chronic disease had higher rates of COVID-19 vaccine acceptance. Beliefs that COVID-19 vaccines are intended to inject microchips into recipients and that the vaccines are related to infertility were found in 27.7% and 23.4% of respondents, respectively. Higher VCBS scores were found among females, respondents with lower educational levels and respondents relying on social media platforms as the main source of information. The high rates of vaccine hesitancy in Jordan and Kuwait, among other Arab countries, are alarming. They could hinder the proper control of COVID-19 in the region. The harmful effect of COVID-19 misinformation and conspiracy beliefs was manifested in vaccine hesitancy. This may represent a massive obstacle to the successful control of the pandemic. A reliance on social media as the main source of information about COVID-19 vaccines was associated with vaccine hesitancy. This should alert governments, policy makers and the general public to the importance of vigilant fact checking.

Temporal increase in D614G mutation of SARS-CoV-2 in the Middle East and North Africa

BACKGROUND

Phylogeny construction can help to reveal evolutionary relatedness among molecular sequences. The spike (S) gene of SARS-CoV-2 is the subject of an immune selective pressure which increases the variability in such region. This study aimed to identify mutations in the S gene among SARS-CoV-2 sequences collected in the Middle East and North Africa (MENA), focusing on the D614G mutation, that has a presumed fitness advantage. Another aim was to analyze the S gene sequences phylogenetically.

METHODS

The SARS-CoV-2 S gene sequences collected in the MENA were retrieved from the GISAID public database, together with its metadata. Mutation analysis was conducted in Molecular Evolutionary Genetics Analysis software. Phylogenetic analysis was done using maximum likelihood (ML) and Bayesian methods.

RESULT

A total of 553 MENA sequences were analyzed and the most frequent S gene mutations included: D614G = 435, Q677H = 8, and V6F = 5. A significant increase in the proportion of D614G was noticed from (63.0%) in February 2020, to (98.5%) in June 2020 (p < 0.001). Two large phylogenetic clusters were identified via ML analysis, which showed an evidence of inter-country mixing of sequences, which dated back to February 8, 2020 and March 15, 2020 (median estimates). The mean evolutionary rate for SARS-CoV-2 was about 6.5 × 10-3 substitutions/site/year based on large clusters' Bayesian analyses.

CONCLUSIONS

The D614G mutation appeared to be taking over the COVID-19 infections in the MENA. Bayesian analysis suggested that SARS-CoV-2 might have been circulating in MENA earlier than previously reported.

COVID-19 misinformation: Mere harmless delusions or much more? A knowledge and attitude cross-sectional study among the general public residing in Jordan

Since the emergence of the recent coronavirus disease 2019 (COVID-19) and its spread as a pandemic, media was teeming with misinformation that led to psychologic, social and economic consequences among the global public. Probing knowledge and anxiety regarding this novel infectious disease is necessary to identify gaps in knowledge and sources of misinformation which can help public health efforts to design and implement more focused interventional measures. The aim of this study was to evaluate the knowledge, attitude and effects of misinformation about COVID-19 on anxiety level among the general public residing in Jordan. This cross-sectional study was conducted using an online-based questionnaire that took place in April 2020, which targeted people residing in Jordan, aged 18 and above. The questionnaire included items on the following: demographic characteristics of the participants, knowledge about COVID-19, anxiety level and misconceptions regarding the origin of the pandemic. The total number of participants included in final analysis was 3150. The study population was predominantly females (76.0%), with mean age of 31 years. The overall knowledge of COVID-19 was satisfactory. Older age, males, lower monthly income and educational levels, smoking and history of chronic disease were associated with perceiving COVID-19 as a very dangerous disease. Variables that were associated with a higher anxiety level during the pandemic included: lower monthly income and educational level, residence outside the capital (Amman) and history of smoking. Misinformation about the origin of the pandemic (being part of a conspiracy, biologic warfare and the 5G networks role) was also associated with higher anxiety levels. Social media platforms, TV and news releases were the most common sources of information about the pandemic. The study showed the potential harmful effects of misinformation on the general public and emphasized the need to meticulously deliver timely and accurate information about the pandemic to lessen the health, social and psychological impact of the disease.

Conspiracy Beliefs Are Associated with Lower Knowledge and Higher Anxiety Levels Regarding COVID-19 among Students at the University of Jordan

The world has been afflicted heavily by the burden of coronavirus disease 2019 (COVID-19) that overwhelmed health care systems and caused severe economic and educational deficits, in addition to anxiety among the public. The main aim of this study was to evaluate the mutual effects of belief that the pandemic was the result of a conspiracy on knowledge and anxiety levels among students at the University of Jordan (UJ). An electronic-based survey was conducted between 29 March, 2020 and 31 March, 2020. The targeted population involved all undergraduate and postgraduate students from the health, scientific and humanities schools at UJ. Survey sections included 26 items on: socio-demographic information, knowledge and sources of information about the disease, attitude towards the false notion that COVID-19 stemmed from a conspiracy and items to assess the anxiety level among students during the quarantine period. The total number of participants was 1540 students. The mean age of study participants was 22 years and females predominated the study population (n = 1145, 74.4%). The majority of participants perceived the disease as moderately dangerous (n = 1079, 70.1%). Males, Jordanians and participants with lower income were more inclined to feel that COVID-19 is very dangerous. A lower level of knowledge and a higher level of anxiety about COVID-19 were associated with the belief that the disease is part of a conspiracy. Females and participants with lower income were more likely to believe that the disease is related to conspiracy. Belief in conspiracy regarding the origin of COVID-19 was associated with misinformation about the availability of a vaccine and the therapeutic use of antibiotics for COVID-19 treatment. The Ministry of Health in Jordan was the most common source of information about COVID-19 reported by the participants (n = 1018). The false belief that COVID-19 was the result of a global conspiracy could be the consequence of a lower level of knowledge about the virus and could lead to a higher level of anxiety, which should be considered in the awareness tools of various media platforms about the current pandemic.

Prevalence and Associates of Foot Deformities among Patients with Diabetes in Jordan

OBJECTIVES

To determine the prevalence of, and factors associated with, people with foot deformities, among patients with diabetes in Jordan.

METHODS

A cross-sectional study was conducted on 1000 diabetic participants recruited from the National Center for Diabetes, Endocrinology, and Genetics in Jordan. Participants had their feet clinically examined to detect the following foot deformity outcomes: Hallux valgus, claw/hammer toe, prominent metatarsal heads, limited joint mobility, pes cavus, Charcot foot, and amputations. Sociodemographic and health variables were also collected from participants' interviews, medical records, or clinical examination. Logistic regression was used to analyse associations between variables and each foot deformity outcome.

RESULTS

Of the 1000 diabetic patients: Hallux valgus was found in 17.4%, claw\hammer toe in 16%, prominent metatarsal head in 14.2%, limited joint mobility in 9.4%, pes cavus in 3.2%, Charcot foot in 2.1%, and amputations in 1.7%. Hallux valgus was associated with gender (p=0.012), age (p<0.01) and shoe choices (p=0.031); claw\hammer toe was associated with age (p=0.04), retinopathy (p<0.001), sensory and painful neuropathy (p<0.001); limited joint mobility was associated with age only (p=0.001); Charcot foot was associated with glycemic control (p=0.016), hypertension (p<0.000), sensory neuropathy (p<0.001), and painful neuropathy (p<0.001); and, amputations were associated with duration of diabetes (p<0.043), sensory neuropathy (p=0.001), and painful neuropathy (p=0.001).

CONCLUSION

Prevalence of different foot deformities in Jordan variedbetween 1.7% - 17.4%. Sociodemographic factors such as age, gender and shoes choices or presence of diabetes-related microvascular complications (neuropathy and retinopathy) or hypertension were independently associated with foot deformities among the Jordanian diabetic population.

Recurrent meningitis in children: etiologies, outcome, and lessons to learn

PURPOSE

Recurrent meningitis in children is a rare condition. However, its early recognition is important in order to prevent serious complications. This study aims to review cases of recurrent meningitis in children.

METHODS

This is a retrospective study that included children diagnosed with recurrent meningitis and who were followed at child neurology clinic at the Jordan University Hospital from January 2001 to June 2017.

RESULTS

Thirteen patients were included (nine males and four females). Age of first episode of meningitis ranged from 2 months to 9.5 years. The delay in diagnosis of the underlying cause after the first episode ranged from 6 months to 2.5 years. Underlying causes included inner ear malformation in one patient, skull fractures in two, and dermal sinuses (thoracic spinal and occipital dermal sinus) in two patients. No identifiable cause was found in eight patients. Streptococcus pneumoniae was identified in four (31%) patients, Staphylococcus aureus in two (15%), and no organism was isolated in seven (54%). Three patients (23.1%) developed neurological sequel including developmental delay, limb spasticity, and epilepsy. Two patients had sensorineural hearing loss related to meningitis, and two patients had sensorineural hearing loss mostly related to their original disease.

CONCLUSION

A detailed history, examination, and thorough investigations are necessary to determine the underlying cause of recurrent meningitis. In addition, in patients with positive CSF bacterial culture, finding the underlying etiology is very likely.

Prevalence of blood-borne viral infections among autopsy cases in Jordan

Background: Morgues are high risk areas for the spread of infection from cadavers to staff during the post-mortem examination. Infection can spread from corpses to workers by airborne transmission, by direct contact, or through needle and sharp object injuries. Objective: Knowledge about the prevalence of these infections on autopsy is essential to determine the risk of transmission and to further enforce safety measures. Methods: This is a descriptive study. All autopsies performed in the Department of Forensic Medicine at Jordan University Hospital during the study period were tested for the serology of human immunodeficiency, hepatitis B and C viruses. Positive tests were confirmed by nucleic acid testing. Results: A total of 242 autopsies were tested. Age ranged from 3 days to 94 years (median 75.5 years, mean 45.3 years (21.9 ±  SD)). There were 172 (71%) males. The cause of death was considered natural in 137 (56.6%) cases, accidental in 89 (36.8%), homicide in nine (3.7%), suicide in four (1.7%), and unknown in three (1.2%) cases. Hepatitis B surface antigen was positive in five (2.1%) cases. Hepatitis C virus antibody was positive in five (2.1%) cases and the hepatitis C virus polymerase chain reaction was positive in two (0.8%) cases. HIV antibody was not detected in any of the cases. The infection status of cases was not associated with age, sex, nationality, or cause of death. Conclusion: The study findings indicated that there is a low prevalence of virus-infected autopsies in Jordan. However, the risk of transmission remains a potential threat and therefore the necessary precautions should always be taken during autopsy.

Congenital insensitivity to pain and anhydrosis due to a rare mutation and that is complicated by inflammatory bowel disease and amyloidosis: a case report

Patients with congenital insensitivity to pain and anhydrosis syndrome are at risk for renal amyloidosis and inflammatory bowel disease. Physicians caring for such patients should be aware of these complications.

Bilateral primary psoas abscesses due to methicillin-resistant Staphylococcus aureus in a neutropenic patient: a case report

Background

Pyogenic abscess of psoas muscles is a rare condition. Psoas abscess due to methicillin-resistant Staphylococcus aureus is an emerging and rare infection and so far the related data are scarce.

Case presentation

We report the rare case of primary and bilateral large psoas abscesses due to methicillin-resistant Staphylococcus aureus in a 54-year-old Arab Jordanian woman with breast cancer who had neutropenia after starting chemotherapy. She was diagnosed 50 days after onset of symptoms. However, despite this delay in diagnosis and the large size of the abscesses, she had a full recovery. She was treated with antibiotics and percutaneous drainage and was doing very well at a follow up of 18 months.

Conclusions

Psoas abscess due to methicillin-resistant Staphylococcus aureus might have insidious presentation with extensive disease especially in immunocompromised patients. However, it can be managed effectively with percutaneous catheter drainage and appropriate antibiotic therapy.

Subacute thyroiditis following influenza vaccine: a case report and literature review

Subacute thyroiditis following influenza vaccination is a rarely reported condition. Here, we review this condition and report the case of a 40-year-old male who developed subacute thyroiditis following the administration of an influenza vaccine containing the (H1N1) pandemic 2009 strain. Interestingly, the patient had history of pericarditis and his HLA typing showed HLA B35. Physicians should be aware of this complication for influenza vaccine and of the relationship of HLA B35 haplotype with the susceptibility to subacute thyroiditis and other autoimmune disorders.

Fatal encephalitis due to BK virus in a patient with common variable immunodeficiency: a case report

Encephalitis due to BK virus is a rare condition. Here, we describe a young male patient with common variable immunodeficiency who developed fatal encephalitis due to BK virus. The patient presented initially with ocular symptoms that were followed by behavioral changes and spastic quadriparesis. Diagnosis was made by the compatible clinical findings and detection of viral DNA by polymerase chain reaction in the cerebrospinal fluid. To the best of our knowledge, this is the first report of BK virus encephalitis in a patient with common variable immunodeficiency. We suggest that BK virus should be suspected in cases of encephalitis; particularly in patients with immunodeficiency.

Peripheral arterial disease in diabetic Jordanian patients and the agreement between ankle brachial index and toe brachial index

This study aims to screen patients with type 2 diabetes mellitus for peripheral arterial disease (PAD) and to determine the agreement between ankle brachial index (ABI) and toe brachial index (TBI). A total of 182 diabetic patients at 40 years of age or older were assessed using both ABI and TBI. Mean age was 60.5 (SD ±8.1) years. PAD was present in 28.9% and 5.4% of patients according to TBI and ABI definitions respectively. The prevalence of high ABI (ABI > 1.3) was 16.5%. The agreement between TBI and ABI results was fair. Current smoking was associated with low ABI whereas age was inversely associated with TBI. We strongly suggest using both the ABI and TBI as screening tests for PAD because the agreement between these tests was fair, they complement each other in most instances and they detect PAD at different anatomical levels.

Pituitary abscess presenting two years after the diagnosis of a pituitary lesion in a patient with panhypopituitarism

Pituitary abscess is a rare condition. Here, we present the case of a young male patient who was initially found to have a pituitary lesion following the diagnosis of panhypopituitarism. Two years later, he presented with severe headache and was subsequently diagnosed intraoperatively with pituitary abscess. At a follow-up of 6 years after surgery, the patient was continuing to do very well. We discuss the differential diagnosis and demonstrate the evolution of the pituitary lesion on magnetic resonance imaging at four different time points: at the time of the detection of the initial lesion; two years later at the time of the diagnosis of the pituitary abscess; at 7 weeks post operatively; and finally after six years from the pituitary surgery.

Mondini malformation associated with diastematomyelia and presenting with recurrent meningitis

The authors report the case of 5-year-old girl who presented with 4 episodes of recurrent meningitis. Her initial workup revealed a lumbosacral dermoid sinus associated with diastematomyelia and a tethered cord. Therefore, a surgical repair to correct the anomaly was performed. However, another episode of meningitis occurred after surgery, and a subsequent temporal bone scan revealed the presence of left Mondini dysplasia. To the authors' knowledge, this is the first report of Mondini dysplasia in association with diastematomyelia.

Narghile (water pipe) smoking among university students in Jordan: prevalence, pattern and beliefs

BACKGROUND AND OBJECTIVES

Narghile is becoming the favorite form of tobacco use by youth globally. This problem has received more attention in recent years. The aim of this study was to investigate the prevalence and pattern of narghile use among students in three public Jordanian universities; to assess their beliefs about narghile's adverse health consequences; and to evaluate their awareness of oral health and oral hygiene.

METHODS

The study was a cross-sectional survey of university students. A self-administered, anonymous questionnaire was distributed randomly to university students in three public Jordanian universities during December, 2008. The questionnaire was designed to ask specific questions that are related to smoking in general, and to narghile smoking in specific. There were also questions about oral health awareness and oral hygiene practices.

RESULTS

36.8% of the surveyed sample indicated they were smokers comprising 61.9% of the male students and 10.7% of the female students in the study sample. Cigarettes and narghile were the preferred smoking methods among male students (42%). On the other hand, female students preferred narghile only (53%). Parental smoking status but not their educational level was associated with the students smoking status. Smokers had also significantly poor dental attendance and poor oral hygiene habits.

CONCLUSION

This study confirmed the spreading narghile epidemic among young people in Jordan like the neighboring countries of the Eastern Mediterranean region. Alarming signs were the poor oral health awareness among students particularly smokers.

Orofacial findings in chronic granulomatous disease: report of twelve patients and review of the literature

BACKGROUND

Chronic granulomatous disease is an extremely rare primary immunodeficiency syndrome that can be associated with various oral complications. This can affect high number of patients. However, data on oral complications is sparse. Here we will review the literature and describe the orofacial findings in 12 patients.

FINDINGS

The age range was 5-31 years. Oral findings were variable, and reflected a low level of oral hygiene. They included periodontitis, rampant caries, gingivitis, aphthous-like ulcers, and geographic tongue. One patient had white patches on the buccal mucosa similar to lichen planus. Another patient had a nodular dorsum of the tongue associated with fissured and geographic tongue. Biopsies from the latter two lesions revealed chronic non-specific mucositis. Panoramic radiographs showed extensive periodontitis in one patient and periapical lesions in another patient.

CONCLUSION

Patients with chronic granulomatous disease may develop oral lesions reflecting susceptibility to infections and inflammation. It is also possible that social and genetic factors may influence the development of this complication. Therefore, oral hygiene must be kept at an optimum level to prevent infections that can be difficult to manage.

Brucellosis presenting as myelofibrosis: first case report

We describe the case of a 29-year-old woman who presented with pancytopenia and myelofibrosis. Brucella melitensis was identified in her blood. The patient recovered completely with doxycycline and rifampin. A repeat bone marrow biopsy showed hypercellularity without myelofibrosis. Bone marrow findings in cases of pancytopenia due to brucellosis reveal normocellularity, hypercellularity, hemophagocytosis, or granuloma. To our knowledge this is the first report of brucellosis causing myelofibrosis. Brucellosis should be considered as a possible cause of myelofibrosis in endemic areas.

First report of clinical, functional, and molecular investigation of chronic granulomatous disease in nine Jordanian families

INTRODUCTION

Chronic granulomatous disease is a rare inherited immunodeficiency syndrome caused by mutations in four genes encoding essential nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex components.

MATERIAL AND METHODS

Clinical, functional, and molecular investigations were conducted in 15 Jordanian CGD patients from nine families.

RESULTS AND DISCUSSION

Fourteen patients were children of consanguineous parents and suffered from autosomal recessive (AR) CGD forms with mutations in the CYBA, NCF1, and NCF2 genes encoding p22phox, p47phox, and p67phox proteins, except for one patient in whom the mutation's location was not found. One patient had an extremely rare X(+)CGD subtype resulting from a novel missense mutation (G1234C) in exon 10 of CYBB. We found a genetic heterogeneity in the Jordanian families with a high frequency of rare ARCGD, probably because consanguineous marriages are common in Jordan. No clear correlation between the severity of the clinical symptoms and the CGD types could be established.

Griscelli syndrome type 2: a rare and lethal disorder

Griscelli syndrome is a rare autosomal recessive disorder. It is characterized by pigment dilution and variable immune deficiency leading to increased susceptibility to certain infections and a tendency to develop a life-threatening hemophagocytic syndrome known as the accelerated phase. Griscelli syndrome is now classified into 3 types based on the genetic and molecular features. Primary neurological presentation without the accelerated phase is rare in type 2. In this article, the authors report a boy who was presented with seizures and diffuse white matter involvement unaccompanied by the other features of the accelerated phase. Mutation analysis in family members revealed the presence of a missense mutation in Rab27a gene. In addition to the rare presentation, this is the first case of Griscelli syndrome to be reported from Jordan.

Persistent bacteraemia due to methicillin-resistant Staphylococcus aureus with reduced susceptibility to vancomycin in a patient with erythrodermic psoriasis

A 49-y-old male with erythrodermic psoriasis developed persistent bacteraemia for 3 months due to methicillin-resistant Staphylococcus aureus despite antimicrobial therapy. The skin was the likely focus. Three consecutive isolates from the blood and 1 from the nose were identical and had vancomycin MIC of 4 mg/l.

Ataxia-telangiectasia complicated by craniopharyngioma--a new observation

Ataxia-telangiectasia is a rare autosomal recessive neurodegenerative disorder with high incidence of malignancy including leukemias, lymphomas, and solid tumors. Central nervous system tumors in ataxia telangiectasia include medulloblastomas and gliomas. We describe a 13-year-old girl with ataxia telangiectasia who developed craniopharyngioma and non-Hodgkin's lymphoma. To our knowledge, this is the first case of ataxia telangiectasia complicated by craniopharyngioma in the English literature.

Diabetic foot infection

Diabetic foot infection DFI is simply defined as suspected or documented infection of the tissues that comprise the foot of a diabetic patient. Diabetic foot infection is often caused by introduction of an infection into the otherwise sterile soft tissues of the foot through a minor skin break down. Diabetic foot infection may be mild usually restricted to the uppermost layers of the skin, moderate extending down to the soft tissues of the foot or severe infection associated with systemic toxicity or metabolic instability. The paper reviews the types of DFI, pathophysiology, microbiology of DFI, relevant anatomy of the foot, clinical evaluation, measures of severity of DFI, the role of radiological investigations, and the role of early surgical intervention in the prevention of progressive foot infection and limb salvage. It is concluded that the diagnosis of DFI should be suspected at an early stage based on the presence of local signs of inflammation with or without systemic signs of toxicity or metabolic instability. Optimal treatment of DFI requires a multimodality approach directed at controlling hyperglycemia, administration of systemic antibiotics, and local wound management to prevent the spread and dissemination of infection.

Successful treatment of Brucella endocarditis with aortic root abscess

Brucella endocarditis is a rare but fatal complication of Brucellosis, it causes destructive valvular lesions. The aortic valve is the most common affected site. We present a case of Brucella endocarditis with aortic root abscess, the patient received a prolonged combination of antibiotic therapy, and underwent aortic valve replacement. After one and a half years of follow up, the patient is still without signs of recurrence. The high mortality in Brucella endocarditis can be overcome by early diagnosis and aggressive therapy.

Respiratory syncytial virus infection in the late bone marrow transplant period: report of three cases and review

Respiratory syncytial virus (RSV) infection is an important cause of respiratory mortality in immunosuppressed patients, including bone marrow transplant (BMT) recipients. The presence of lower respiratory tract infection and infection in the pre-engraftment phase of BMT is believed to confer a poor prognosis. Three patients who underwent allogeneic BMT at our institution developed RSV pneumonia over 1 year post BMT, with the underlying disease in remission. All three were hypoxic with extensive pulmonary disease at presentation. Treatment consisted of aerosolized ribavirin and intravenous immune globulin with successful clearing of viral shedding and excellent clinical outcomes. RSV infection is probably less severe in the late post-BMT period, but needs to be considered early in the differential diagnosis of pulmonary infiltrates in this patient population.
