Epstein-Barr virus-associated smooth muscle tumor (EBV-SMT) is a rare tumor found in immunocompromised patients, and its treatment is not well-established. A role for antiretroviral therapy in human immunodeficiency virus (HIV)-related EBV-SMT has been proposed; however, the relevance of tumor size, CD4 levels, and immune reconstitution inflammatory syndrome (IRIS) has not been previously reported. We present the first case, to our knowledge, of a tumor that shrank in association with elevated CD4 counts. IRIS occurred in this case following antiretroviral therapy. This finding highlights the importance of the immune response in HIV-related EBV-SMT.
Identifying child abuse is sometimes challenging due to its various presentations. To facilitate timely identification of critical or complex cases of physical abuse outside our child protection center, we established an outreach multidisciplinary team (OMDT) to support Kaohsiung City Government in 2014. The objective of this study was to describe our experience of OMDT services during a 6-year period and examine its role in assisting law enforcement.We retrospectively analyzed all OMDT cases from January 2014 to January 2020. Clinical characteristics and OMDT reports were reviewed. After inspection by our OMDT, cases were determined as indicating either a high risk or low risk of child abuse. Associations among clinical characteristics, radiographic findings, OMDT decisions and case outcomes including law enforcement and prosecution were examined.Thirty-two cases (22 [68.8%] males and 10 [31.2%] females; mean age 24.2 months) received OMDT service, of whom 28 (87.5%) were admitted to the pediatric intensive care unit. The victims had an average of 2.2 types of wounds in 3.4 locations. The most common finding on radiography was subdural hemorrhage (18, 56.3%), followed by subarachnoid hemorrhage (31, 31.3%). Law enforcement was activated in 20 (64.5%) cases, and was only associated with the high-risk group as determined by the OMDT (p < 0.05) but not with any other variables.Our experience indicates that an OMDT can play an important role in child protection and activating law enforcement for children with complex or critical physical abuse. We suggest that in Taiwan, OMDT services should be incorporated into child protection centers, National Health Insurance system and governmental child protection policies.
Exertional headache is one entity of Valsalva maneuver-related headache syndrome. It is usually idiopathic, but has occasionally been reported to be associated with secondary causes. However, central nervous system infection has not been mentioned before. We encountered a young man who suffered an isolated exertional headache and was found to have an active varicella-zoster virus central nervous system infection without typical intracranial hypertension or outfl ow obstruction. Intracranial vasoconstriction was detected during headache when the patient performed acute lifting or heavy exertion. The fi ndings in this patient suggest a specifi c relationship between varicella-zoster virus-related vasculopathy and exertional headache from other Valsalva maneuver-related headache syndrome.
Nummular headache (NH) is a newly categorized headache disorder characterized by a consistent clinicographics in each attack. Currently, it is considered as a primary headache disorder due to epicranial neuralgia but the pathomechanism is still unknown. We report a woman, whose recurrent NH subsided after trans-sphenoidal surgery for her pituitary oncocytoma. The recovery of NH in this patient encourages the central mechanism for NH occurrence. After a review of literature concerning, NH and intracranial secondaries we propose that central NH is a referral pain from pain-sensitive structures, such as meninges, superimposing by pre-existing lower pain threshold or pain modulation.
<b><i>Background:</i></b> Although it has been established that antiphospholipid antibodies (APAbs) bind to and modulate the signaling of cerebellar neurons in vitro, the clinical correlation between increased APAbs and cerebellar ataxia has rarely been investigated. <b><i>Methods:</i></b> We reviewed 10 patients presenting with cerebellar ataxia with increased blood APAbs from our database along with 3 APAb-associated cerebellar ataxia patients in the literature. <b><i>Results:</i></b> Of these 10 patients, 4 exhibited a subacute onset of progressive ataxia, and there were no significant structural changes in their brains that appeared to be responsible for the symptoms. Another 6 showed a chronic course of ataxia, and shared similar morphological changes that included symmetrical lesions in bilateral hemispheres, periventricular lucency and central and temporal atrophy of varying severity; the cerebellum was spared. The predominant APAbs for subacute and chronic ataxia were the anti-beta<sub>2</sub>-glycoprotein I antibody and anticardiolipin antibody, respectively. Cancer was found in 1 patient with subacute ataxia and in 4 with chronic ataxia. The removal of the cancer, the plasmapheresis and immunosuppressive therapy successfully abolished the ataxia and increased APAb levels in all 5 patients. <b><i>Conclusions:</i></b> The relation between APAbs and nonvascular neurological disorders, such as cerebellar ataxia, should be further studied. APAbs may mediate neurological deficits via different mechanisms such as structural damage or functional neurotoxicity. Clinically, the examination of blood APAb levels is recommended for patients with cerebellar ataxia without a determined cause, and the further survey of systemic cancers in the case of APAb positivity is also recommended. Finally, plasmapheresis is a reasonable and effective treatment for APAb-associated cerebellar ataxia.
Lipoid pneumonia is an uncommon disease that results from pulmonary accumulation of a fat-like component. The diagnosis is based on clinical history, radiologic presentation and bronchoalveolar lavage (BAL) sample analysis. We report the case of a 46-year-old male who presented with cough, fever and pleuritic chest pain after diesel oil aspiration. Chest radiograph on admission revealed consolidation in the right lower lung field; an antibiotic was administered to treat aspiration pneumonia. Bronchoscopy revealed some oily, transparent, yellowish fluid in the right lower bronchus, but culture and cytology of BAL fluid showed negative results. The follow-up chest radiograph revealed no obvious improvement after antibiotic treatment. Chest computed tomography (CT) revealed consolidation in the right middle lobe with heterogeneous density, and CT-guided biopsy revealed necrotizing inflammation. A follow-up bronchoscopy showed mucosal inflammation. Steroid was administered to treat the lipoid pneumonia and inflammation, and obvious improvement of the clinical symptoms and radiologic manifestations was seen. No specific adverse effect or complication was noted during therapy. In patients with lipoid pneumonia, careful history-taking and diagnosis are important. Steroid is effective for these patients.
Amitriptyline is an old drug but is still prevalently used as the first-line treatment for a variety of common diseases. Surprisingly, knowledge of sexual risks with amitriptyline comes from only one clinical trial and several case reports from three decades ago. In the current study, a systematic review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) related to amitriptyline and sexual dysfunction (SD) was performed. The frequency, gender-difference, types, disease-specificity and time course of SD, and the relationship between SD and nonsexual adversity were studied. A total of 14 publications, including 8 qualified randomized clinical trials, were eligible. The frequency of SD in overall, male and female patients was 5.7, 11.9 and 1.7%, respectively. SD was six-fold higher in men than women. The frequency of SD was 6.9% in depressive patients compared with 0.8% in non-depressive patients ( p = .008), and gradually decreased at 8 weeks after treatment ( p = .02). Amitriptyline impacted arousal and libido more than orgasm and ejaculation in male patients but mainly libido in female patients. SD was significantly correlated with insomnia linearly whereas somnolence and nausea dually. Therefore, amitriptyline-associated SD mainly occurs in depressive and male patients, disturbs each phase of the sexual response cycle in men but mainly libido in women, gradually decreases under long-term treatment, and can be predicted by the co-existence of insomnia, somnolence or nausea during treatment. Clinicians should caution and tailor the gender and disease vulnerability of amitriptyline in their practice.
