Background: Lupus Nephritis (LN) is one of the most common and serious manifestations in Systemic Lupus Erythematosus (SLE) patients that causes significant morbidity and mortality. Certain biomarkers for LN are sometimes able to assess treatment response of lupus nephritis. Objective: To compare serum complement levels (C3 & C4) as markers of treatment response of LN and their relation to the LN class in renal biopsy. Methods: This prospective observational study was conducted in the Department of Nephrology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2018 to August 2019. Twenty seven patients who were diagnosed with lupus nephritis after kidney biopsy were included in this study. Serum complement levels (C3 & C4), 24 hours urinary total protein (24-hr UTP) and anti-double-stranded DNA (anti-ds DNA) were measured in all patients at baseline, 3 months and 6 months after treatment. These biomarker values before and after treatment were compared between the treatment response and non response groups. Results: Serum C3 levels were significantly different in patients of proliferative lupus nephritis (Class III & Class IV) than non proliferative lupus nephritis (Class V) at baseline (0.47 ± 0.32 vs0.89 ± 0.43g/l, p = 0.009) and levels changed significantly 6 months after treatment (p <0.001) and likewise for Serum C4 levels (0.10 ± 0.06 vs0.24 ± 0.26g/l, p = 0.040). Serum C3 levels were also found to correlate significantly with SLEDAI and renal SLEDAI. No significant difference was observed for 24-hr UTP levels at baseline between remission and non-remission groups. Conclusion: Serum C3 & C4 levels may be utilized as serological biomarkers to predict and monitor the treatment response of lupus nephritis.

Abstract Background Warts are a common dermatologic complaint resulting from infection with HPV which spread by direct skin-to-skin contact or by autoinoculation. The clinical appearance of warts is variable depends on the type of HPV involved and the site of infection. There are various types of viral warts including common warts, plantar warts, plane warts and genital warts, usually diagnosis of warts is made through clinical examination of the lesions and no laboratory investigations are required. Objective To compare between the therapeutic efficacy and safety of needling versus homologous autoimplantation techniques in treatment of multiple plantar warts and assess their recurrence rate. Patients and Methods Our study included 40 patients with multiple de novo planter warts(3 -10 warts) of (&gt;1 and &lt;3 years duration) divided into 2 groups, 20 patients per group, one group subjected to autoimplantation of wart tissue and the other subjected to needling procedure. Follow up of studied patients was assessed by physician after 2,8 and 12 weeks of procedure through clinical and dermoscopic examination to assess treatment response and after 16 weeks to assess recurrence Results Results of our study reported that there was high statistically significant difference between the 2 studied groups as regard response to treatment after 12 weeks being higher among autoimplantation group (p = 0.001). Moreover, there were no significant relations between treatment response of both patient groups and each of gender, age of patients, number of warts and duration of lesions. Conclusion Autoimplantation technique is more effective and less painful than needling procedure in treatment of multiple plantar warts (both manipulated and remote warts). No significant relations were found between treatment response of either techniques and demographic or clinical characteristics of studied patients.

Serial neuropsychological testing potentially provides a powerful tool for tracking disease progress and identifying treatment response. Formal neuropsychometric assessment by a clinical psychologist is ideal but impractical for regular testing. Remote computerised assessment resolves this difficulty by allowing frequent home assessment, but is potentially limited by patient compliance and practise effects. We study the feasibility of this approach in an on-going clinical trial investigating the effects of methylphenidate on cognition after traumatic brain injury (TBI): Dopamine's Role in Enhancing Attention and Memory (DREAM).A battery of neuropsychological tests was delivered on an iPad. 12 patients with moderate/severe TBI and on-going cognitive complaints completed 7 tasks assessing information processing speed, memory, attention and executive functions. The 25-minute-long battery was performed daily for 4 weeks, following an initial training period. Compliance was good, with over 80% of the sessions completed, and patients found it both beneficial and enjoyable. Despite optimising the battery to minimise learning effects, differing tasks showed varying degrees of practise effects.We demonstrate a proof of principle that TBI patients will enthusiastically complete regular computerised neuropsychological tests at home. This provides a potentially powerful tool to assess treatment response, but also offers the prospect of facilitating self-directed cognitive rehabilitation.

Imaging is integral in the management of patients with thymoma and thymic carcinoma. At initial diagnosis and staging, imaging provides the clinical extent of local invasion as well as distant metastases to stratify patients for therapy and to determine prognosis. Following various modalities of therapy, imaging serves to assess treatment response and detect recurrent disease. While imaging findings overlap, a variety of CT, MRI, and PET/CT characteristics can help differentiate thymoma and thymic carcinoma, with new CT and MRI techniques currently under evaluation showing potential.
