Fulltext Simultaneous Bilateral Optic Neuritis Following Human Papillomavirus Vaccination in a Young Child

Michael NDB, Tuan Jaffar TN, Hussein A, Wan Hitam WH

Cureus, 2018 Sep 24;10(9):e3352.
PMID: 30510863 DOI: 10.7759/cureus.3352

Vaccination-induced optic neuritis is not common. The development of optic neuritis following various vaccinations have been reported, suggesting a possible association between optic neuritis and vaccination. Of those reported cases, influenza vaccines have been the most common. Although rare, those patients who developed optic neuritis following HPV vaccination also presented with other central nervous system (CNS) demyelinating syndromes, especially following a booster dose. We present a rare case of simultaneous isolated bilateral optic neuritis following the first dose of an HPV vaccination in a young child. She received treatment with a systemic corticosteroid that resulted in a good clinical outcome without developing any demyelinating disease.
Meningioma Mimicking Fibrous Dysplasia

Kamaluddin NA, Samsudin AHZ, Wan Hitam WH, Ibrahim M

PMID: 31723541 DOI: 10.7759/cureus.5782

Despite being among the common primary intracranial tumors, intraosseous craniofacial meningioma is the least common subtype of meningioma accounting for only 1-2% of intracranial meningiomas. Interestingly, it can display clinical and radiologic features that can be confused for fibrous dysplasia. Scan imaging and biopsy are crucial for the diagnosis as well as for further proper treatment. We report a case of unilateral eye proptosis and optic neuropathy which was initially thought for fibrous dysplasia. Later the histopathology revealed meningioma grade 1. As the clinical presentations are almost undifferentiated, diagnosis and further prompt treatment are challenging.
Fulltext Conjunctiva Necrosis Following Subconjunctival Amphotericin B Injection in Fungal Keratitis

Han Shu T, Hussein A, Kursiah MR

Cureus, 2019 Sep 05;11(9):e5580.
PMID: 31695999 DOI: 10.7759/cureus.5580

A 30-year-old Bangladeshi gentleman presented with history of sand entering his left eye and was diagnosed as having fungal keratitis by private ophthalmologist. He was treated with three doses of conventional subconjunctival amphotericin B injections (1.5 mg of amphotericin B and 1.2 mg of deoxycholate) over the inferior bulbar conjunctiva and topical antibiotics. Subsequently, he developed conjunctival necrosis over the site of injections and there was no clinical improvement of the keratitis. He was then treated with intensive antifungal and antibiotics eye drops. Debridement of epithelial plug was done and he was given intracameral amphotericin B injection. There was gradual improvement observed then with conjunctival epithelialization. The conjunctival tissue was completely healed after three months along with the corneal ulcer. Subconjunctival injection of Amphotericin B (AMB) may be considered as an adjunct therapy in severe fungal keratitis to address the issue of compliance. Close monitoring is needed due to its known complication of scleritis, scleral thinning and conjunctival necrosis. Liposomal AMB which is known to cause less toxicity given via subconjunctival injection in human subjects needs to be further studied.
Incidental Trifid Median Nerve Unveiled in a Lactating Mother

Siddiq MAB, Hossain Parash MT

Cureus, 2019 Sep 30;11(9):e5809.
PMID: 31728251 DOI: 10.7759/cureus.5809

Several anatomical variations concerning the median nerve have surfaced in the medical literature. Among them, bifid median nerve or median nerve bifurcation with or without persistent median artery has been widely reported. Sporadic case reports describe median nerve trifurcation (trifid median nerve) as well. In the present report, we describe carpal tunnel syndrome manifestations in association with trifid median nerve unveiled incidentally under high-frequency musculoskeletal ultrasonogram in a lactating mother-a first in the medical literature.
Fulltext A Rare Case of Purulent Pericardial TB

Johari MI, Ramli AW, Mat Lawi F, Bin Fouzi MAH, Suardi KPS

Cureus, 2019 Aug 09;11(8):e5356.
PMID: 31608191 DOI: 10.7759/cureus.5356

Pericardial effusion is a common disease and tuberculosis (TB) accounts up to 4% of acute pericarditis with up to 7% of tamponade case. Accurate diagnosis is important while quick intervention can be life-saving. A case was reported involving a 73-year-old man who presented with reduced effort tolerance for one-month duration. During hospitalization, further workup revealed the presence of massive purulent pericardial effusion with evidence of tamponade. TB gene expert was positive in aspirated pericardial fluid and the patient was treated promptly using a combination of anti-TB drugs with the addition of steroid therapy.
Fulltext Tuberculosis of the Left Wrist Joint and Spine

Sivasamy P, Bajuri MY, Ghani AW

Cureus, 2019 Nov 19;11(11):e6203.
PMID: 31890405 DOI: 10.7759/cureus.6203

The incidence of wrist tuberculosis is rare. Clinical features and radiographs are not conclusive in the beginning, happen to delay the achievement of the diagnosis, and thus result in poor treatment. We present a case report of wrist tuberculosis that had delayed diagnosis. Hence, the initiation of antituberculous treatment was delayed, as the initial investigations were not conclusive of tuberculous infection. The patient was treated surgically multiple times before tuberculosis was diagnosed. Antituberculous chemotherapy was started for the patient for one year until she became afebrile and infective markers returned to normal. However, the patient developed left wrist stiffness due to arthrofibrosis and bony destruction of the wrist joint.
Fulltext Hair Thread Tourniquet Syndrome in an Infant: Emergency Exploration Saves Limbs

Kesu Belani L, Leong JF, Narin Singh PSG, Abdullah S

Cureus, 2019 Dec 13;11(12):e6377.
PMID: 31938655 DOI: 10.7759/cureus.6377

Hair thread tourniquet syndrome (HTTS) is a rare condition where fibres constrict around appendages causing ischaemia and necrosis. It is a sporadically reported condition, where almost all reported cases showed involvement of fingers, toes or genitalia. A significant number of the cases are infants aged two weeks to six months where it is attributed to the mother's excessive hair fall due to hormonal changes after delivery. We present a two-month-old infant who was irritable for the past two days with her left ring finger exhibiting an ischaemic constriction with no apparent insulting agent. She successfully treated surgically after we suspected an incomplete removal of hair thread in the emergency department. We would like to highlight the importance of a high index of suspicion in cases as such as early intervention saves the appendage.
Fulltext Improvement of "Bouncy Gait" in Lance-Adams Syndrome with Perampanel

Lim SY, Jasti DB, Tan AH

Cureus, 2020 Jan 25;12(1):e6773.
PMID: 32117660 DOI: 10.7759/cureus.6773

Lance-Adams syndrome (LAS) is chronic post-hypoxic myoclonus that is often associated with sudden lapses in muscle tone (negative myoclonus) in the legs, causing a disabling "bouncy gait." Given its relative rarity, there are no controlled treatment studies of LAS. The majority of cases require polypharmacy management, with an incomplete response. "Bouncy gait," in particular, is notoriously medication-refractory. Here, we report a patient with long-standing LAS who improved markedly when low-dose perampanel was added to his existing treatment regime consisting of clonazepam, levetiracetam, sodium valproate, and acetazolamide.
Fulltext Hemi-hamate Arthroplasty in Chronic Fracture-dislocation of Proximal Interphalangeal Joint of Fingers: A Report of Two Cases

Arsad SR, Sem SH, Silvanathan JP, Muhammad Nawawi RF

Cureus, 2020 Jan 22;12(1):e6735.
PMID: 32140316 DOI: 10.7759/cureus.6735

Dorsal dislocations of proximal interphalangeal joint with palmar lip fractures base of middle phalanx of fingers are rare, complex, and often a challenging injury to the treating hand surgeons especially in those chronic cases. Hemi-hamate arthroplasty is the preferred surgical option in treating chronic dorsal fracture-dislocations of the proximal interphalangeal joint. We report two cases with a chronic injury that have been treated with hemi-hamate arthroplasty. Range of motion, pinch and grip strengths, QuickDASH scores, complications, and radiological findings were recorded at follow-up. Good functional outcomes were observed in both patients without major complications. Hemi-hamate arthroplasty can be a reliable surgical treatment for chronic proximal interphalangeal joint fracture-dislocations.
Fulltext Caecocentral Scotoma: A Rare Presentation of Optic Perineuritis

Mohamad SA, Zunaina E, Wan Hitam WH

Cureus, 2019 Nov 08;11(11):e6101.
PMID: 31886042 DOI: 10.7759/cureus.6101

Optic perineuritis (OPN) is a subtype of optic neuritis (ON) in which the inflammatory process involves meningeal sheath surrounding the optic nerve. Clinically, OPN simulates ON. However, in contrast to ON, patient with OPN shows sparing of central vision, improves dramatically with high-dose corticosteroid, are more likely to experience recurrence after stopping treatment. We report a rare case of caecocentral scotoma observed in a female with typical ON symptoms. Her magnetic resonance imaging showed features in line with OPN. She was treated with intravenous methylprednisolone 1 g/day for five days followed by slow tapering dose of oral prednisolone for one month. Her vision improved dramatically with a resolution of visual field defect. No relapses seen within two years of follow-up.
Fulltext Atypical Cavernous Sinus Thrombosis: A Diagnosis Challenge and Dilemma

Matthew TJH, Hussein A

Cureus, 2018 Dec 04;10(12):e3685.
PMID: 30761237 DOI: 10.7759/cureus.3685

Cavernous sinus thrombosis (CST) is an ocular emergency because of its devastating effect and it is prone to cause serious complications. Diagnosis of cavernous sinus thrombosis is a challenging task despite medical advancement. Efforts to promptly diagnose and initiate treatment require a high index of suspicion and a deep understanding of the disease. Unfortunately, patients suffering from CST may not always present with typical symptoms, thus making diagnosis all the more challenging. We would like to describe a 22-year-old man who presented with atypical symptoms and radiological presentations of CST. The patient was admitted and treated in our institution with full recovery demonstrated after the treatment.
Fulltext Rare and Unique Case of Midline Anterior Arch of Atlas Non-formation Mimicking Jefferson Type 1 Fracture

Das S, Palaniandy K, Abu Bakar A, Idris Z, Abdullah JM

Cureus, 2020 Feb 03;12(2):e6850.
PMID: 32181085 DOI: 10.7759/cureus.6850

Cervical spine injuries are rare occurrences in children, especially the congenital anomalies of the atlas vertebra. Any injury involving the craniovertebral junction such as Jefferson fracture, is a valid cause for alarm due to the complex nature of the craniovertebral junction and the morbidity associated with it. We report the case of a 10-year-old male, who had failure of fusion of anterior arch of atlas due to the failure of formation of the anterior midline synchondrosis, and this mimicked a Jefferson fracture. If it was not for the peculiar absence of any corresponding evidence to suggest spinal injury, we might have mistaken this extremely rare but benign anomaly for a Jefferson fracture and subjected the patient to needless surgical treatment. Hence, it is concluded that keen clinical acumen and clear understanding of the developmental anatomy of these patients may be necessary to adequately manage them.
Fulltext Hidden Choroidal Melanoma Presented with Bullous Non-rhegmatogenous Retinal Detachment in a Myopic Asian Lady: A Rare Manifestation

Ibrahim N, Sakinah Z, Abdul Ghani Z, Ibrahim M

Cureus, 2019 Mar 27;11(3):e4335.
PMID: 31187000 DOI: 10.7759/cureus.4335

Choroidal melanoma is an uncommon malignant melanoma among non-Caucasians. We report here a case of a high myope patient who presented with symptoms of acute retinal detachment, which had been diagnosed as possible rhegmatogenous retinal detachment from the initial assessment. A detailed vitreoretinal evaluation revealed a glimpse of an obscured intraocular mass underneath the detached retina, which later proved to be a choroidal melanoma. This is an unexpected cause of retinal detachment in a myopic eye. Furthermore, the rare nature of choroidal melanoma in this particular region of the world makes this an ignored diagnosis at presentation.

Punitan R, Sulaiman SA, Hasan HB, Shatriah I

Cureus, 2019 Mar 27;11(3):e4332.
PMID: 31186997 DOI: 10.7759/cureus.4332

Introduction Pseudomonas aeruginosa is a common cause of microbial keratitis that can cause a significant loss of visual acuity. Antibiotics, including fluoroquinolones and aminoglycosides, are clinically effective against Pseudomonas-induced keratitis, but their effectiveness has been conspicuously reduced as resistant pathogens have become more potent. This study sought to evaluate the clinical and antibacterial effects of tualang honey as an alternative therapeutic agent against Pseudomonas-induced keratitis. Methods We conducted a randomized control trial in which 30 rabbits were injected intrastromally with 1,000 colony-forming units (CFU) of Pseudomonas aeruginosa in the right eye of each rabbit (n = 30). The rabbits were then randomized into three groups of 10 rabbits each. Group A was treated with topical gentamicin 0.3%, group B was treated with topical tualang honey 30%, and group C received both treatments. The specified treatments were administered every two hours from 24 to 48 hours post injection, and subsequently every four hours for six days. Clinical examinations were performed on days one, two, three, five, and seven, and the mean results of slit lamp examinations (SLEs) were documented. On day seven after pseudomonas induction, the rabbits were euthanized and their corneas were harvested to determine the median CFU per cornea. Results There were no statistically significant differences (p > 0.05) in mean SLE scores (p = 0.209) or median CFU values (p = 0.820) between the three groups. Conclusion Topical gentamicin, topical tualang honey, and the combination of the two all showed similar clinical and antimicrobial effects in treating Pseudomonas-induced keratitis in rabbits. These findings should be verified in further studies with larger sample sizes and the addition of a control group.
Fulltext Bilateral Inferior Altitudinal Visual Field Defect in Recurrent Intracranial Meningioma: A Case Report

Ghanimi Zamli AK, Chew-Ean T, Wan Hitam WH

Cureus, 2019 Apr 11;11(4):e4436.
PMID: 31245223 DOI: 10.7759/cureus.4436

Altitudinal visual field defect is a rare presentation of retrochiasmal lesion especially when bilateral visual fields were affected. In fact, bilateral inferior altitudinal visual field defect (BIAVFD) usually occurred in patients who survived a gunshot injury to the occipital lobe or as a direct trauma to the brain. We report a rare case of BIAVFD secondary to occipital meningioma. A high index of suspicion enables timely investigation and diagnosis when dealing with atypical presentation of intracranial meningioma.
Fulltext Study of Visual Function in Adult Epileptic Patients on Sodium Valproate or Carbamazepine Monotherapy

Matthew TJH, Tharakan J, Tai E, Hussein A

Cureus, 2019 Apr 27;11(4):e4553.
PMID: 31275777 DOI: 10.7759/cureus.4553

Objective Epilepsy is a debilitating disease. Visual function changes have been reported and may be attributed to the epileptic changes or as a result of medication side effect. Sodium valproate and carbamazepine are both first line anti-epileptic medications used in Malaysian health care. Sodium valproate inhibits glutamate and γ-aminobutyric acid (GABA) transaminase while carbamazepine acts on the sodium channel - both are an important part of the retina. This study aimed to compare the visual functions of epilepsy patients on carbamazepine or sodium valproate monotherapy. Design A cross-sectional study was conducted at a tertiary hospital between June 2016 and November 2018. Methods Patients with idiopathic epilepsy that fulfill the inclusion and exclusion criteria were recruited from the neurology clinic. They were divided into two groups and underwent complete eye examinations. Visual functions such as color vision testing, contrast sensitivity, visual field and retinal nerve fiber layer measurement were subsequently performed. Statistical analysis was done using Statistical Package for the Social Science, version 24 (SPSS Inc, Chicago, IL, USA). Results A total of 100 patients (sodium valproate: 50 patients; carbamazepine: 50 patients) were recruited for the study. There were no statistically significant changes in anatomical or visual function between the sodium valproate and carbamazepine group. However, patients from both groups displayed color vision defect in the blue and green axes. Changes in color vision could indicate early retina toxicity secondary to the medication. Although there were no visual field changes, patients recorded a slight reduction of mean deviation. Changes of mean deviation could be attributed to the side effect of medication or the disease process. Conclusions Epileptic patients taking sodium valproate or carbamazepine did not demonstrate statistically significant change in visual function.

Takotsubo syndrome (TTS), also known as Takotsubo cardiomyopathy, is a transient left ventricular wall dysfunction that is often triggered by physical or emotional stressors. Although TTS is a rare disease with a prevalence of only 0.5% to 0.9% in the general population, it is often misdiagnosed as acute coronary syndrome. A diagnosis of TTS can be made using Mayo diagnostic criteria. The initial management of TTS includes dual antiplatelet therapy, anticoagulants, beta-blockers, angiotensin-converting enzyme inhibitors or aldosterone receptor blockers, and statins. Treatment is usually provided for up to three months and has a good safety profile. For TTS with complications such as cardiogenic shock, management depends on left ventricular outflow tract obstruction (LVOTO). In patients without LVOTO, inotropic agents can be used to maintain pressure, while inotropic agents are contraindicated in patients with LVOTO. In TTS with thromboembolism, heparin should be started, and patients should be bridged to warfarin for up to three months to prevent systemic emboli. Our comprehensive review discussed the management in detail, derived from the most recent literature from observational studies, systematic review, and meta-analyses.
Fulltext Isolated Tuberculosis of the Wrist: Subtle but Destructive

Manas A, Bajuri MY, Muhammad Nawawi RF

Cureus, 2020 May 03;12(5):e7939.
PMID: 32499979 DOI: 10.7759/cureus.7939

Tuberculosis is an infection that can occur in every organ of the body, but it rarely affects the wrist joint. We report a rare case of a male patient with wrist tuberculosis with a subtle presentation. Our patient's left wrist had been swollen for four months and progressively worsened, becoming ulcerated one week prior to presentation to our center. He was asymptomatic, but a previous radiograph showed global destruction of the wrist joint. Clinical investigations, that is, polymerase chain reaction test for tuberculosis and histopathological examination, showed classic findings of tuberculosis, which lead to the initiation of anti-tuberculosis treatment.
Fulltext Caregiving Self-efficacy and Knowledge Regarding Patient Positioning Among Malaysian Caregivers of Stroke Patients

Tan CE, Hi MY, Azmi NS, Ishak NK, Mohd Farid FA, Abdul Aziz AF

Cureus, 2020 Mar 24;12(3):e7390.
PMID: 32337117 DOI: 10.7759/cureus.7390

Background Most family caregivers of stroke patients in Malaysia do not receive adequate prior preparation or training. This study aimed to determine levels of patient positioning knowledge and caregiving self-efficacy among caregivers of stroke patients. Methods This cross-sectional study was conducted at an urban teaching hospital involving 128 caregivers of stroke patients. The caregivers were conveniently sampled and completed the data collection forms, which comprised their socio-demographic data, patients' functional status, the Caregiving Knowledge For Stroke Questionnaire: Patient Positioning (CKQ-My© Patient Positioning) to measure caregiver's knowledge on patient positioning, and the Family Caregiver Activation Tool (FCAT©) to measure caregivers' self-efficacy in managing the patient. Descriptive and multivariate inferential statistics were used for data analysis. Results Among the caregivers sampled, 87.3% had poor knowledge of positioning (mean score 14.9 ± 4.32). The mean score for FCAT was 49.7 ± 6.0 from a scale of 10 to 60. There was no significant association between knowledge on positioning and self-efficacy. Multiple linear regression showed that caregivers' age (B = 0.146, p = 0.003) and caregiver training (B = 3.302, p = 0.007) were independently associated with caregivers' self-efficacy. Conclusion Caregivers' knowledge on the positioning of stroke patients was poor, despite a fairly good level of self-efficacy. Older caregivers and receiving caregiver training were independently associated with better caregiver self-efficacy. This supports the provision of caregiver training to improve caregiver self-efficacy.
Fulltext Effects of Methotrexate Therapy on the Levels of Gonadotropic Hormones in Rheumatoid Arthritis Patients of Reproductive Age

Kyaw MT, Sakthiswary R, Ani Amelia Z, Rahana AR, Munirah MM

Cureus, 2020 Apr 11;12(4):e7632.
PMID: 32399364 DOI: 10.7759/cureus.7632

BACKGROUND: Methotrexate (MTX), which is the anchor drug in rheumatoid arthritis (RA), targets actively proliferating cells including the oocytes and granulosa cells which may impair the ovarian reserve. The purpose of this study was to determine the effects of MTX therapy on gonadotropic hormones, i.e. follicular stimulating hormone (FSH) and luteinizing hormone (LH) in female RA patients of reproductive age.
MATERIALS AND METHODS: This is a cross-sectional study conducted at the Universiti Kebangsaan Malaysia Medical Centre (UKMMC), from January 2018 to July 2018. Women with RA aged between 15 and 49 years who were on MTX therapy for at least six months, were consecutively recruited. All subjects were interviewed to gather information on their menstrual history and menopausal symptoms. The medical records were reviewed to obtain further data on the disease characteristics and RA treatment. The RA disease activity was determined using the DAS 28 scoring system. All subjects were tested for their serum FSH and LH levels.
RESULTS: A total of 40 patients were included in this study. The median dose of MTX used by the subjects was 12.5 mg weekly. The mean cumulative MTX dose was 1664.92 ± 738.61 mg. More than half (53.1%) of the subjects reported menopausal symptoms especially hot flushes. We found that FSH levels had a significant positive correlation with cumulative MTX dose [(r = 0.86), p < 0.001] and the duration of MTX therapy [(r = 0.84), p < 0.001]. Besides, there was a significant relationship between disease activity based on DAS 28 and FSH levels (p < 0.01). Age, body mass index, disease duration, and weekly MTX dose showed no associations with the FSH levels. On multivariate analysis, DAS 28 was found to be the only parameter that remained significant [β = 1.74 (95% CI 1.17-2.31), p < 0.001]. The LH levels, on the other hand, were not associated with MTX therapy or disease activity.
CONCLUSION: Higher levels of FSH, which is an indicator of diminished ovarian reserve, have a significant positive relationship with disease activity, cumulative dose, and duration of MTX therapy in RA.
