Atypical Mpox in a Nigerian Tertiary Health Facility.

BACKGROUND: We describe diverse clinical characteristics and course of confirmed mpox cases managed in a Nigerian tertiary health facility. METHODS: Clinical and epidemiologic data were analyzed, highlighting the unusual presentations of polymerase chain reaction (PCR)-confirmed mpox cases observed during the 2022 outbreak. RESULTS: Out of 17 suspected cases, 13 (76.4%) were PCR confirmed for mpox. The mean ± SD age for the participants was 28.62 ± 10.29 years (range, 2-55), of which 9 (64.3%) were male. Of the 13 PCR-confirmed cases, 5 (38.5%) had varicella zoster virus coinfection, 2 (15.4%) had HIV coinfection, and 1 (7.7%) had diabetes mellitus comorbidity. All patients experienced rash, with 6 (46.2%) having significant genital lesions and 1 (7.7%) having a severe perianal lesion. A lack of prodromal symptoms was reported in 3 (23.1%), and a prolonged prodrome (>1 week) occurred in 5 (38.5%). Skin lesions were polymorphic in 6 (46.2%), and solitary skin lesions occurred in 3 (23.1%), which persisted for >120 days in 7.7%. CONCLUSIONS: Clinical recognition, diagnosis, and prevention remain a concern in resource-limited settings. Our findings highlight the need to further evaluate unusual skin lesions and to include mpox screening for genital skin lesions that are presumed to be sexually transmitted infections. Revision of clinical case definition and enhanced surveillance are key to early recognition and prevention of spread.

Lessons from a scoping review: Clinical presentations of central centrifugal cicatricial alopecia.

BACKGROUND: Central centrifugal cicatricial alopecia (CCCA) nomenclature describes a typical clinical presentation of cicatricial hair loss that begins on the vertex scalp with progressive, symmetric, and centrifugal evolution. However, atypical presentations have been noted clinically by the authors and reported in the literature. OBJECTIVE: We sought to characterize the distribution of hair loss in published cases of adult patients with CCCA. METHODS: A 3-step search process was used to evaluate research articles in Cumulative Index to Nursing & Allied Health, EMBASE, Google Scholar, MEDLINE, Scopus, and Web of Science databases. Studies with scalp photography or description of hair loss distribution were included. Three researchers evaluated eligible studies for clinical subtypes. Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Review was used to report results. RESULTS: Ninety-nine studies consisting of 281 cases of CCCA were included. Hair loss distributions included variants of the classic presentation along with distinct subtypes such as patchy, occipital, parietal, frontal, temporal, and trichorrhexis. LIMITATIONS: Studies had significant homogeneity, as the classic distribution of CCCA was commonly reported. Additionally, clinically diagnosed cases may have concurrent diagnoses, and numerous studies did not report trichoscopy findings. CONCLUSION: CCCA terminology may not always be reflective of clinical presentation. Understanding atypical presentations is essential to inform appropriate and targeted treatment.

Elderly patients with non-specific complaints at the emergency department have a high risk for admission and 30-days mortality.

BACKGROUND: Older adults have complex medical needs that causes increased use of resources at the emergency department (ED). The prevalence of non-specific complaint (NSC) as a chief-complaint in the ED is common among older adults and is not prioritized even though possibly having worse clinical outcome. The objective was to study hospital admission and mortality for older adults visiting the ED with NSC compared to specific complaints such as dyspnea, chest pain and abdominal pain. METHODS: A retrospective observational study of older adults visiting the ED with NSC and specific complaints; dyspnea, chest pain and abdominal pain was performed. Chief-complaint were collected from electronic medical records. Fatigue, confusion, non-specific complaints, generalized weakness and risk of falling were defined as non-specific complaint (NSC) when registered as chief-complaint at the ED. Admission rate and 30-days mortality were the primary outcomes. RESULTS: A total of 4927 patients were included in the study based on chief-complaint; patients with chest pain 1599 (32%), dyspnea 1343 (27%), abdominal pain 1460 (30%) and NSC 525 (11%). Patients with dyspnea and NSC had the highest hospital admission rate 79% vs 70% compared to patients with chest pain (63%) and abdominal pain (61%) (p = < 0.001). Patients with NSC had a mean LOS 4.7 h at the ED which was significantly higher compared to chest pain, dyspnea and abdominal pain. Mean bed-days for the whole population was 4.2 days compared to patients with NSC who had a mean LOS of 5.6 days. NSC and dyspnea were both associated with the highest 30-day mortality. CONCLUSION: Older patients who present with NSC at the ED are associated with a high risk for admission and 30-days mortality. In addition, patients with NSC have a longer LOS at the ED, a high admission rate and the highest number of bed-days once admitted. This study indicates that ED staff should be more vigilant when an elderly patient presents with NSC at the ED. Further studies and guidelines are needed to improve the management of these individuals.

Central centrifugal cicatricial alopecia in males.

BACKGROUND: Central centrifugal cicatricial alopecia (CCCA) is a scarring alopecia seen primarily in women of African descent but rarely reported in men. The etiology of CCCA is unknown, but genetic variants, type 2 diabetes mellitus, and bacterial infections may play a role. OBJECTIVES: We aimed to characterize the demographics, medical histories, and clinical findings of male patients with CCCA with the hypothesis that features may differ from women. METHODS: This was a case series of adult male patients with biopsy-confirmed CCCA seen at an academic dermatology department between 2012 and 2022. RESULTS: In total, 17 males had a scalp biopsy and clinical findings consistent with CCCA. The average age was 43 years, and 88.2% of cases identified as Black race. Scalp pruritus was the most common symptom, and few patients endorsed high-risk hair care practices. None of the cases had diagnosis of type 2 diabetes mellitus, but 17.6% had history of latent tuberculosis, and 47.1% had a positive family history of alopecia. We observed 8 patients with atypical CCCA, and 29.4% had an overlapping scalp diagnosis. LIMITATIONS: This study is limited by the single center, retrospective design and small sample size. CONCLUSIONS: It is important to consider CCCA in the differential diagnosis of alopecia in adult Black males.

Atypical presentation of cutaneous meningioma.

Cutaneous meningiomas are rare tumors of ectopic meningeal tissue in the dermis or subcutis and are most commonly located on the scalp and around the eyes, ears, nose, and mouth. We present a case of cutaneous meningioma with an unusual presentation on the upper arm, but with positivity for epithelial membrane antigen to support the diagnosis of meningioma. Lack of pancytokeratin AE1/3 and p63 allowed us to rule out a keratinocytic tumor, such as squamous cell carcinoma and basal cell carcinoma. The absence of smooth muscle actin, FXIIIa, CD163, and CD34 allowed us to rule out a leiomyoma, dermatofibroma, and vascular neoplasm respectively. Weak staining of S100 allowed us to rule out a perineuroma. The purpose of this case report is to increase awareness of a rare presentation of cutaneous meningioma not located within the scalp/face region. This may broaden its inclusion within differential diagnoses of neoplasms of uncertain behavior and encourage correct clinical diagnosis, thus improving treatment outcomes.

Invasive meningococcal disease in older adults in North America and Europe: is this the time for action? A review of the literature.

BACKGROUND: Neisseria meningitidis is an encapsulated Gram-negative diplococcus that asymptomatically colonises the upper respiratory tract in up to 25% of the population (mainly adolescents and young adults). Invasive meningococcal disease (IMD) caused by Neisseria meningitidis imposes a substantial public health burden,. The case fatality rate (CFR) of IMD remains high. IMD epidemiology varies markedly by region and over time, and there appears to be a shift in the epidemiology towards older adults. The objective of our review was to assess the published data on the epidemiology of IMD in older adults (those aged ≥ 55 years)in North America and Europe. Such information would assist decision-makers at national and international levels in developing future public health programmes for managing IMD. METHODS: A comprehensive literature review was undertaken on 11 August 2020 across three databases: EMBASE, Medline and BIOSIS. Papers were included if they met the following criteria: full paper written in the English language; included patients aged ≥ 56 years; were published between 1/1/2009 11/9/2020 and included patients with either suspected or confirmed IMD or infection with N. meningitidis in North America or Europe. Case studies/reports/series were eligible for inclusion if they included persons in the age range of interest. Animal studies and letters to editors were excluded. In addition, the websites of international and national organisations and societies were also checked for relevant information. RESULTS: There were 5,364 citations identified in total, of which 76 publications were included in this review. We identified that older adults with IMD were mainly affected by serogroups W and Y, which are generally not the predominant strains in circulation in most countries. Older adults had the highest CFRs, probably linked to underlying comorbidities and more atypical presentations hindering appropriate timely management. In addition, there was some evidence of a shift in the incidence of IMD from younger to older adults. CONCLUSIONS: The use of meningococcal vaccines that include coverage against serogroups W and Y in immunization programs for older adults needs to be evaluated to inform health authorities' decisions of the relative benefits of vaccination and the utility of expanding national immunization programmes to this age group.

Acute limb ischemia in a cancer patient has high morbidity, high mortality, and atypical presentation: a tertiary cancer center's retrospective study.

BACKGROUND: Acute Limb Ischemia (ALI) carries a high morbidity and mortality rate that is compounded in the cancer patient. Though it is a relatively uncommon event, it is of extremely high adverse impact and carries poor awareness among clinicians. METHODS: Retrospective review of electronic medical records was performed of cancer patients presenting with acute limb ischemia (ALI) to the tertiary cancer center's urgent care center or as inpatient between January 1, 2014 and January 1, 2020. RESULTS: Out of the 29 cancer patients with ALI, 12 (41%) died within 3 month and 9 (31%) patients died within 1 months of ALI diagnosis. 65% had long term adverse outcome after ALI - 31% with death in 1 month, 2 (7%) with an amputation, 5 (17%) with lifestyle-limiting claudication, and 3 (10%) with subsequent wound ulceration or gangrene. Patients not eligible for standard of care (12 patients, 41%) (RR 2.33 95% CI [1.27-4.27], p <  0.01) and heparin administration ≥6 h from presentation (19 patients, 65%) (RR 2.81 [1.07-7.38], p = 0.04) were at increased risk of adverse outcome. Atypical/confounded presentation of ALI (13 patients, 45%) (RR 1.84 95% CI [1.03-3.29], p = 0.04), pulse exam not documented (12 patients, 41.4%) (RR 1.95 [95% CI [1.14-3.32], p = 0.01), and patients with services other than a vascular specialist initially consulted (8 patients, 27.6%) (RR 1.91 95% CI [1.27-2.87], p <  0.01) were significant risk factors for heparin administered ≥6 h from presentation. CONCLUSIONS: ALI is devastating in cancer patients, with a high number presenting with atypical/confounded signs and symptoms which delays treatment. Heparin administered ≥6 h from presentation is associated with adverse outcome.

GIST of the stomach masquerading as recurrent falls in an older adult: a case report and review.

BACKGROUND: Gastric tumors become increasingly prevalent with advanced age but can be challenging to diagnose in older adults who may present with non-specific symptoms. Here, we report a rare case of an occult gastric tumor associated with mesenteric panniculitis that presented with recurrent falls precipitated by vertigo. CASE PRESENTATION: We describe a diagnostically challenging case of cryptogenic gastric tumor associated with mesenteric panniculitis in a 74-year-old female who presented with abdominal bloating and recurrent falls precipitated by vertigo, dehydration, acute kidney injury and electrolyte deficiencies, but had no alarm symptoms. Her symptoms resolved after laparoscopic wedge resection of the gastric tumor. CONCLUSIONS: Our case highlights that while alarm symptoms such as dysphagia, weight loss, gastrointestinal bleeding and vomiting are considered indications for endoscopy, clinicians should also maintain a high index of suspicion for gastric tumors in older patients who may present with atypical symptoms.

Atypical Antenatal Presentation of an Unusual Nonmucinous Papillary Variant of Giant Congenital Pulmonary Airway Malformation Masquerading as Congenital Diaphragmatic Hernia with Volvulus.

We report a case of a huge congenital pulmonary airway malformation (CPAM) that was referred as congenital diaphragmatic hernia (CDH). Initial ultrasound evaluation revealed a huge cystic lesion with septations, in the thorax, causing mediastinal shift and compression effects, suggesting the possibility of a thoracic lymphangioma, or bowel herniation with obstruction. A fetal magnetic resonance imaging reported possible bowel herniation through a posterior defect in the diaphragm, with volvulus, reinforcing the diagnosis of CDH. It was only on autopsy and subsequent histopathology examination that the diagnosis of a rare variant of CPAM-nonmucinous papillary type, could be made. To the best of our knowledge, a CPAM this huge has not been reported prenatally at this gestation. We recommend considering the potential diagnosis of CPAM in any thoracic cystic irrespective of its size or appearance.

DNMT3B deficiency presenting as severe combined immune deficiency: A case report.

Immunodeficiency, Centromeric instability and Facial anomalies (ICF) syndrome is a group of rare autosomal recessive disorders. The immune disease in the ICF syndrome consists mainly of humoral immunodeficiency. T-cell dysfunction has previously been suspected to be part of the syndrome's spectrum. However, patients with ICF display, at a young age, a normal number of T cells that tend to decline throughout disease progression due to apoptosis. Biallelic mutations in the DNMT3B gene account for around 50% of ICF cases (ICF type 1). The remaining half may be linked to ZBTB24, CDCA7 or HELLS. Here we report a novel homozygous DNMT3B mutation (NM_ 006892; p.R826H) in a Lebanese family presenting in early infancy with severe combined immune deficiency (SCID). This work expands the clinical spectrum of the ICF syndrome and confirms the importance of tailoring therapeutic approaches for each patient with ICF syndrome, according to the clinical manifestations of his disease.

Prospective study of the additional benefit of plexus magnetic resonance imaging in the diagnosis of chronic inflammatory demyelinating polyneuropathy.

BACKGROUND AND PURPOSE: Hypertrophy/signal hyperintensity and/or gadolinium enhancement of plexus structures on magnetic resonance imaging (MRI) are observed in two-thirds of cases of typical chronic inflammatory demyelinating polyneuropathy (CIDP). The objective of our study was to determine the additional benefit of plexus MRI in patients referred to tertiary centers with baseline clinical and electrophysiological characteristics suggestive of typical or atypical CIDP. METHODS: A total of 28 consecutive patients with initial suspicion of CIDP were recruited in nine centers and followed for 2 years. Plexus MRI data from the initial assessment were reviewed centrally. Physicians blinded to the plexus MRI findings established the final diagnosis (CIDP or neuropathy of another cause). The proportion of patients with abnormal MRI was analyzed in each group. RESULTS: Chronic inflammatory demyelinating polyneuropathy was confirmed in 14 patients (50%), as were sensorimotor CIDP (n = 6), chronic immune sensory polyradiculoneuropathy (n = 2), motor CIDP (n = 1) and multifocal acquired demyelinating sensory and motor neuropathy (n = 5). A total of 37 plexus MRIs were performed (17 brachial, 19 lumbosacral and 8 in both localizations). MRI was abnormal in 5/37 patients (14%), all of whom were subsequently diagnosed with CIDP [5/14(36%)], after an atypical baseline presentation. With plexus MRI results masked, non-invasive procedures confirmed the diagnosis of CIDP in all but one patient [1/14 (7%)]. Knowledge of the abnormal MRI findings in the latter could have prevented nerve biopsy being performed. CONCLUSION: Systematic plexus MRI in patients with initially suspected CIDP provides little additional benefit in confirming the diagnosis of CIDP.

Atypical presentation of COVID-19 in a frail older person.

Common symptoms of pandemic coronavirus disease (COVID-19) include fever and cough. We describe a 94-year-old man with well-controlled schizoaffective disorder, who presented with non-specific and atypical symptoms: delirium, low-grade pyrexia and abdominal pain. He was given antibiotics for infection of unknown source, subsequently refined to treatment for community-acquired pneumonia. Despite active treatment, he deteriorated with oxygen desaturation and tachypnoea. A repeat chest X-ray showed widespread opacification. A postmortem throat swab identified COVID-19 infection. He was treated in three wards over 5 days with no infection control precautions. This has implications for the screening, assessment and isolation of frail older people to COVID-specific clinical facilities and highlights the potential for spread among healthcare professionals and other patients.

Clinical characteristics of elderly pulmonary tuberculosis in an acute-care general hospital in Tokyo, Japan: A 12-year retrospective study.

OBJECTIVE: A significant feature of tuberculosis (TB) in Japan is the fact that a high proportion of cases belong to the elderly population. Furthermore, previous reports have pointed out the delayed diagnosis of pulmonary TB in acute-care settings. We aimed to examine the clinical characteristics of pulmonary TB patients in an acute-care general hospital, particularly focusing on the elderly population. METHODS: We retrospectively reviewed the medical records of patients with pulmonary TB who presented at our institution between May 2005 and December 2016. We described the overall clinical characteristics of these patients and compared them according to age. RESULTS: Overall, 289 patients were eligible for the analysis, with a median age of 58 [42-73] years, and 29.4% being older than 70 years. Among the elderly patients, 42.4% were characterized by atypical presentation. CONCLUSION: Our findings suggest that the elderly population tends to present as atypical cases lacking respiratory complaints, thereby being at a risk of misdiagnosis.

A case report of an atypical presentation of pyogenic iliopsoas abscess.

BACKGROUND: Iliopsoas abscess is a collection of pus in the iliopsoas muscle compartment. It can be primary or secondary in origin. Primary iliopsoas abscess occurs as a result of hematogenous or lymphatic seeding from a distant site. This is commonly associated with a chronic immunocompromised state and tends to occur in children and young adults. Secondary iliopsoas abscess occurs as a result of the direct spread of infection to the psoas muscle from an adjacent structure, and this may be associated with trauma and instrumentation in the inguinal region, lumbar spine, or hip region. The incidence of iliopsoas abscess is rare and often the diagnosis is delayed because of non-specific presenting symptoms. CASE PRESENTATION: We describe a patient with iliopsoas abscess who presented to the Emergency Department at X Hospital on three separate occasions with non-specific symptoms of thigh pain and fever before finally being admitted for treatment. This case illustrates how the diagnosis can be delayed due to its atypical presentation. Hence, highlighting the need for clinicians to have a high index of clinical suspicion for iliopsoas abscess in patients presenting with thigh pain and fever. CONCLUSION: The classic triad of fever, flank pain, and hip movement limitation is presented in only 30% of patients with iliopsoas abscess. Clinicians should consider iliopsoas abscess as a differential diagnosis in patients presenting with fever and thigh pain. The rare condition with the varied clinical presentation means that cross-sectional imaging should be considered early to reduce the risk of fulminant sepsis.

Unusual presentation of Henoch-Schönlein purpura.

Henoch Schonlein Purpura (HSP) is a systematic IgA-mediated vasculitic disease that affects the small vessels of the skin, the joints, the gastrointestinal tract and the kidneys (1). It is the most common childhood vaculitis, with an incidence estimated at 3-26 per 100,000 children, and with a male-to-female ratio of 2:1 (2-6). The 90% of patients are under 10 years of age, with a mean age of 4 years (4). It seems to be most common in fall and winter in children, and summer and winter in adults (7). Recent studies suggested a strong genetic predisposition in individuals with immunoglobulin Avasculitis (IgAV) associated to HLA class II region. Clinically, the non-thrombocytopenic purpura often located on lower extremities and buttocks is the essential element for the diagnosis of HSP. Treatment is supportive, because the disease is usually benign and self-limited. Indeed, in children, the prognosis is good, with a self-limited course and without any complications and after a median follow-up of 12 months, complete recovery was obtained in 83% of the IgAV patients (4, 8). The aim of our study is to describe some atypical presentations of the HSP in children.

The pharmacological treatment of chronic comorbidities in COPD: mind the gap!

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is commonly associated with other chronic diseases, which poses several diagnostic and therapeutic problems. Indeed, important comorbidities frequently remain unrecognized and, then, untreated, whereas respiratory drugs may have non respiratory side effects, and selected non respiratory drugs may variably affect the respiratory function. OBJECTIVE: to describe: how COPD affects the presentation and contributes to the diagnostic challenges of its most common comorbidities; how coexisting COPD impacts the therapeutic approach to selected comorbidities and viceversa. METHODS: we distinguish comorbidities of COPD depending upon whether they are complications of COPD or share risk factors, mainly smoke, with it or, finally, aggravate COPD. We describe atypical presentations of and diagnostic clues to comorbidities and suggest screening procedures. Finally, the main therapeutic problems, as resulting from the risk of untoward effects of therapies of COPD and its comorbidity, with special attention to drug-drug interactions and possible overdosages, are described. RESULTS: selected complications of COPD, such as osteoporosis, sarcopenia and dysphagia, are rarely recognized and treated, likely due to the poor awareness of them. Important comorbidities, such as coronary artery disease, chronic heart failure, obstructive sleep apnoea syndrome and chronic renal failure, also should be systematically searched for because of their commonly variant presentation. Disease-related symptoms should be distinguished from drug effects or drug-drug interaction effects. CONCLUSIONS: a truly comprehensive view of the complex COPD patient, hopefully capitalizing on multidimensional geriatric assessment, is needed to dissect the many components of health status impairment and to provide the optimal care. Selected screening procedures are highly desirable to identify frequently missed comorbidities. Pharmacosurveillance is an essential part of the approach to COPD and its comorbidities.

Stroke as an atypical initial presentation of giant cell arteritis.

BACKGROUND: Giant cell arteritis (GCA) is an immune mediated inflammatory disease of medium and large arteries which afflicts older people. The classical presentation features include: headache, visual disturbances, and jaw claudication. Patients diagnosed with GCA have also been observed to be at higher risk for the subsequent development of strokes. CASE PRESENTATION: We describe a case of an 84-year old right-handed man who presented to hospital with dysarthria, dysphagia, right-sided facial drop, a history of generalized weakness and multiple falls. He was admitted to geriatric medicine with the working diagnosis of a posterior circulation stroke syndrome. He was also started on antibiotic treatment for a possible community-acquired pneumonia because of the presence of a low-grade fever and a chest radiograph showing ill-defined left lower lobe airspace disease. Initial lab results were remarkable for an erythrocyte sedimentation rate (ESR) of 112 mm/h and a C-reactive protein (CRP) level of 110 mg/L consistent with an active inflammatory state. Neurovascular imaging showed mild atherosclerotic changes of the aortic arch and proximal great vessels without significant stenosis. The patient was started on daily high-dose prednisone because of the possibility of a cerebral vasculitis. Bilateral biopsy of temporal arteries showed giant cell arteritis. The patient's neurologic status and inflammatory markers significantly improved (ESR 52 mm/h, CRP 7.0 mg/L) and he was eventually discharged to a seniors home with services. CONCLUSION: The initial presentation of giant cell arteritis as a stroke syndrome, especially in the posterior circulation territory, is exceedingly rare. Other atypical presenting symptoms may include chronic cough and fever of unknown origin. The elevated ESR and CRP levels were clues to the diagnosis and clinical decision-making should be driven by a high index of suspicion since no single test (ESR, CRP, temporal artery biopsy) has perfect sensitivity. Elevated CRP may have a role in increasing stroke risk. This case report illustrates that in older people clinicians must consider atypical presentations of disease more often since timely diagnosis and initiation of treatment can result in optimal outcomes.

Distant metastasis as the sole initial manifestation of well-differentiated thyroid carcinoma.

Thyroid carcinoma usually presents as a neck lump. Distant metastasis as the sole initial manifestation of well-differentiated thyroid carcinoma (WDTC) is rare and little is known about these patients. The aim of this study is to characterize patients who present with distant metastasis as the sole initial manifestation of WDTC. Retrospective review of case records of WDTC seen at the National Cancer Centre Singapore from 2002 to 2015 was performed. Patients with no prior complaint of neck swelling and whose first presentation was distant metastatic WDTC were included. Patient demographics, disease characteristics, radiological imaging, histopathology, types of treatment administered, and survival outcomes were examined. Nineteen out of seven hundred and thirty-two cases fulfilled inclusion criteria. Mean age was 65.4 years. All patients presented with osseous (36.8%), pulmonary (31.6%), cerebral metastases (5.3%), or a combination of two out of three aforementioned sites (26.3%). Follicular thyroid carcinoma was most common (47.4%), followed by papillary (36.8%) and medullary (15.8%). More than two-thirds of patients had multiple metastatic foci. Thirteen out of nineteen patients (68.4%) underwent total thyroidectomy with or without neck dissection and adjuvant RAI, while the rest declined surgery. The mean length of follow-up was 40.1 ± 5.1 months and 5-year disease-specific survival was 48.0 ± 17.2%. Distant metastasis without a history of neck swelling as the initial presentation of WDTC is extremely rare. Osseous metastasis and follicular thyroid carcinoma are the most common metastatic site and etiology, respectively. Disease-specific survival at 5-year post-diagnosis is lower compared to patients with thyroid carcinoma diagnosed with distant metastasis on further work-up.

Pericardial Herniation of Small Bowel Post Minimally Invasive Hybrid Maze of Atrial Fibrillation.

BACKGROUND: Herniation of intraabdominal contents into the pericardial cavity is exceptionally rare, and when seen, it is most often the result of trauma, postsurgical complication, or genetic defect. There have been only a few case reports describing spontaneous bowel herniation into the pericardium in minimally invasive cardiac procedures like cardiac ablation, pacemaker placement, and minimally invasive coronary artery bypass graft. CASE REPORT: We report the case of a 65-year-old man who presented to an urgent care center complaining of abdominal and chest pain. This patient had recently undergone a laparoscopic hybrid maze procedure and ultimately had an incarcerated loop of small bowel herniate into the pericardial sac. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We present this case to increase awareness among emergency physicians of the diagnosis of a pericardial hernia in patients presenting with gastrointestinal or cardiorespiratory symptoms after surgical procedures involving the diaphragm.

A case series of atypical presentation of Zika Virus infection in Singapore.

BACKGROUND: The World Health Organization's and Centers for Disease Control and Prevention's definition of Zika infection are symptoms of fever, rash, joint pain, myalgia, headache and conjunctivitis. The diagnosis of Zika infection is based on the clinical history, physical examination and laboratory investigations which includes blood and urine Zika virus Polymerase Chain Reaction. CASE PRESENTATION: Two patients presented with atypical presentation of Zika infection to Sengkang Health, Alexandra Hospital during the recent Zika outbreak in Singapore in August 2016. Madam A presented with isolated generalized rash with no fever, joint pain, myalgia, headache or conjunctivitis. Mr. B presented with isolated fever of 39.4 °C with no rash, joint pain, myalgia, headache or conjunctivitis. Both patients' blood Zika Polymerase Chain Reactions were positive at the time of presentation. CONCLUSION: The described case reports illustrated the challenges that our community Family Physicians faced in diagnosing patients infected with Zika virus. Coupled with the knowledge that most patients are asymptomatic, Family Physicians need to have a high index of clinical suspicion for early identification of patients infected with Zika virus, so as to institute timely treatment and appropriate measures to mitigate the outbreak of Zika infection in the community. Appropriate epidemiological measures such as ensuring prompt and thorough contact tracing of the cases are instrumental in the control of this public health problem.
