Assessment of quality of life using WHOQOL-BREF in patients with visceral leishmaniasis.

BACKGROUND: This study was aimed to assess the impact of quality of life using WHOQOL-BREF in patients with Visceral leishmaniasis (VL). METHODS: A total of 95 VL cases and 95 healthy participants filled out the questionnaires. Data on socio-demographic aspects along with disease duration were collected. Data were compared using a t-test, analysis of variance and chi-square test. RESULTS: VL patients experienced very high impact on their quality of life. Study cohort had male preponderance (72.63%). Majority (64.21%) were aged < 40 years. Longer disease duration was found to have significantly poor quality of life (p < 0.05). The physical domain was found to be most affected domains of quality of life (QOL). QOL was affected most in illiterate, married, housewife, rural population and patients with longer disease duration (p < 0.05). The psychological and environmental domains were significantly affected in > 40 years of age group married patients (p < 0.05). CONCLUSIONS: VL significantly impaired the patients' (QOL) in all four domains (physical, psychological, social relationship and environmental). Physical domain was significantly the most affected domain.

Inclusion of 2-Mercaptoethanol in Lysis Buffer Could Interfere with Isolation of High Molecular Weight DNA from Freshwater Microalgae.

2-mercaptoethanol (2-ME), alongside polyvinylpyrrolidone is commonly used in plant DNA extractions to deal with polyphenols, which could interfere with extraction and downstream applications. 2-ME is also commonly used to denature proteins and nucleases, especially RNAses. On the contrary, we found that the presence of 2-ME in lysis buffer interfered with DNA extraction from 12 strains of freshwater microalgae, resulting in DNA with poor integrity. We also found that the TNES-urea buffer, commonly used for preservation and DNA extraction from fish, appears as effective as the SDS and CTAB buffer for some microalgae strains. Results from our study suggests that the inclusion of 2-ME in DNA extraction protocols may be detrimental for isolation of good quality DNA from freshwater microalgae, and therefore recommend eliminating it or testing varying concentrations of 2-ME when developing species-specific extraction protocols for microalgae.

Dysplastic changes secondary to cytomegalovirus-induced Lipschutz ulcer: Unraveling complexity.

Lipschutz ulcer is a rare nonvenereal condition affecting predominantly young females who are not sexually exposed and can be triggered by various infectious agents, trauma, and drugs. It presents with single or multiple painful ulcers over labia minora, labia majora, vestibule, and lower part of the vagina and may be preceded by prodromal symptoms akin to influenza or mononucleosis. Diagnosis is based on specific criteria, which include age, ulcer characteristics, and absence of immunodeficiency. Management involves reassurance, supportive measures, and in severe cases, corticosteroids. This case highlights the importance of considering cytomegalovirus as a potential causative agent in Lipschutz ulcer and a cause for dysplasia.

A Split Face Comparative Interventional Study to Evaluate the Efficacy of Fractional Carbon Dioxide Laser against Combined use of Fractional Carbon Dioxide Laser and Platelet-Rich Plasma in the Treatment of Acne Scars.

Background: Fractional carbon dioxide laser (FCL) is an established treatment option for acne scars, but use of platelet-rich plasma (PRP) as an adjuvant still requires elaborate studies. Aim: To compare the efficacy and safety of FCL alone and combined use of FCL with PRP in the treatment of acne scars. Materials and Methods: This was a split-face (right-left) comparative study including 32 patients with moderate to severe acne scars. The patients underwent three sessions of FCL along with PRP and FCL alone on right and left sides of the face, respectively, at an interval of 6 weeks. Goodman and Baron qualitative and quantitative scores were used for the evaluation of results along with visual analog scale (VAS) for patient satisfaction and physician assessment of scars. Adverse effects following the procedure were also evaluated and compared. Results: There was significant improvement of scars over both sides of the face, but the difference between right and left sides was not statistically significant according to Goodman and Baron qualitative (p 0.9115) and quantitative score (p 0.6957). On assessing VAS score, patients were more satisfied with the right side, but the values were not statistically significant (p 0.8571). Physician assessment grading showed comparable results over both the sides (p 1). There was no difference in adverse effects between both sides of the face. Conclusions: Inclusion of intradermal PRP to FCL did not produce any statistically significant synergistic effects in the treatment of acne scars.

Adalimumab-induced sensory vasculitic neuropathy.

Vasculitis and other autoimmune conditions are known complications of tumour necrosis factor alpha (TNF-α) inhibitor use. By definition, TNF-α inhibitor induced vasculitis is a secondary systemic vasculitis. However, its phenotype is varied and can present as an isolated vasculitic neuropathy. This presents a diagnostic challenge as the gold standard for diagnosis of a vasculitic neuropathy is a peripheral nerve biopsy that meets predefined histopathological criteria. Given the poor sensitivity of the peripheral nerve biopsy, it is important that clinicians take a good history and maintain a high index of suspicion, as this is a treatable iatrogenic condition. Here we present a case of adalimumab-induced sensory vasculitic neuropathy, treated according to the Peripheral Nerve Society guideline for non-systemic vasculitic neuropathy, given her disease phenotype.

Lesson of the month 2: Transient reversible amnesia in multiple sclerosis.

Transient amnestic syndromes are fascinating clinical entities and there are several subtypes. Transient global amnesia (TGA) is characterised by sudden onset of anterograde amnesia with repetitive questioning, lasting less than 24 hours. The pathophysiology of TGA involves the medial temporal lobes and hippocampi. Episodes of TGA are thought to involve venous congestion with Valsalva-like activities, vascular or migrainous mechanisms. In contrast, transient epileptic amnesia manifests as brief and frequent episodes of amnesia due to seizure activity in the temporal lobes. Transient memory disturbances can also be caused by transient ischaemic attack. We describe the first reported case of transient reversible amnesia directly attributable to acute demyelination. This case reminds us that multiple sclerosis relapses may present with acute cognitive impairment rather than the more classical physical symptoms. This is an important learning point in terms of appropriate management and eligibility for disease-modifying drugs.

Binocular vision and eye movement disorders in older adults.

PURPOSE: To determine the prevalence of binocular vision (BV) and eye movement disorders in a clinic population of older adults. METHODS: Retrospective clinic data were abstracted from files of 500 older patients seen at the University of Waterloo Optometry Clinic over a 1-year period. Stratified sampling gave equal numbers of patients in the 60 to 69, 70 to 79, and 80+ age groups. Data included age, general and ocular history and symptoms, use of antidepressants, a habit of smoking, refraction, visual acuity, BV and eye movement status for the most recent full oculo-visual assessment, and an assessment 10 years prior. The prevalence of any BV or eye movement abnormal test (AT) result, defined as a test result outside the normal range, was determined. This included strabismus (any) or phoria; incomitancy; poor pursuits; and remote near point of convergence (NPC). The prevalence of significant BV disorders (diagnostic entities, i.e., a clinical condition that may need treatment and may have functional implications) was also determined. RESULTS: The prevalence of any BV or eye movement at was 41%, 44%, and 51% in the 60 to 69, 70 to 79, and 80+ age groups, respectively. These figures were lower for 10 years earlier: 31%, 36%, and 40% for ages 50 to 59, 60 to 69, and 70+, respectively. The prevalence of any BV or eye movement disorder was 27%, 30%, and 38% for the three age groups and 17%, 19%, and 24% for 10 years prior. Age and use of antidepressants most commonly predicted BV or eye movement AT or disorder. CONCLUSIONS: BV disorders are common among older adults.
