Twelfth rib syndrome: role of intercostal blocks: case series of 10 patients

Twelfth rib syndrome (TRS) is a rare condition that causes severe pain in the loin. It is often misdiagnosed, leading to unnecessary investigations and treatments. Intercostal blocks in the 11th and 12th rib often resolve the pain for these patients. In this research paper, we aim to explore the role of intercostal block in the management of TRS based on our experience with 10 patients. Data of patients who were diagnosed with TRS were studied retrospectively from our hospital records who have been given intercostal block injection from the period of Jan 2022 to August 2023 as an audit.  Four patients underwent intercostal blocks. VAS scores were measured in follow-up for 1 and 3 months. 4 patients were lost to follow up and hence not considered in this study. The male to female ratio was 7:3. There was a statistically significant reduction in VAS score at 1 month and 3 months compared to pre-injection times. Patients who have failed conservative management for TRS can be effectively managed with intercostal block injections

Cost benefit analysis of intralesional injections in keloids using Luer lock and non-locking syringes

Background: For keloid scarring, intralesional corticosteroid injections continue to be the most often utilised first therapeutic option. This is a common procedure done on an outpatient basis by surgeons and orthopaedists. Luer lock syringes which lock the needle with syringe prevent any leakage or spillage of drug while pushing it near the keloid compared to normal syringes. Methods: We intend to do a cost benefit analysis based on the retrospective data of intralesional steroid injections done by the authors (AP and SK) in their private practice. Results: The time between 2021 to 2022, 200 injection data was retrieved, 100 each using non locking syringes and Luer lock syringes. The spillage rate with non-Luer lock syringes was 14%. Conclusions: We found that luer lock syringes prove to be cost effective after giving more than 200 injections in keloids than non-locking syringes.

Introducing Catastrophe-QSAR. Application on Modeling Molecular Mechanisms of Pyridinone Derivative-Type HIV Non-Nucleoside Reverse Transcriptase Inhibitors

The classical method of quantitative structure-activity relationships (QSAR) is enriched using non-linear models, as Thom’s polynomials allow either uni- or bi-variate structural parameters. In this context, catastrophe QSAR algorithms are applied to the anti-HIV-1 activity of pyridinone derivatives. This requires calculation of the so-called relative statistical power and of its minimum principle in various QSAR models. A new index, known as a statistical relative power, is constructed as an Euclidian measure for the combined ratio of the Pearson correlation to algebraic correlation, with normalized t-Student and the Fisher tests. First and second order inter-model paths are considered for mono-variate catastrophes, whereas for bi-variate catastrophes the direct minimum path is provided, allowing the QSAR models to be tested for predictive purposes. At this stage, the max-to-min hierarchies of the tested models allow the interaction mechanism to be identified using structural parameter succession and the typical catastrophes involved. Minimized differences between these catastrophe models in the common structurally influential domains that span both the trial and tested compounds identify the “optimal molecular structural domains” and the molecules with the best output with respect to the modeled activity, which in this case is human immunodeficiency virus type 1 HIV-1 inhibition. The best molecules are characterized by hydrophobic interactions with the HIV-1 p66 subunit protein, and they concur with those identified in other 3D-QSAR analyses. Moreover, the importance of aromatic ring stacking interactions for increasing the binding affinity of the inhibitor-reverse transcriptase ligand-substrate complex is highlighted

Biologia Futura: treatment of wastewater and water using tannin-based coagulants

Industrialization and urbanization are mainly responsible for environmental pollution generating enormous amount of waste- water which needs to be treated. Wastewaters from various sources are toxic to humans and livestock, as well as posing environmental risks. Various treatment approaches have been used for the elimination of contaminants from water and wastewater. Coagulation/flocculation processes are the most commonly used techniques in water treatment for improving the condition of turbid water and removing suspended particles by destabilization and the creation of larger, heavier flocs that aid in sedimentation. Flocculants, both organic and inorganic, have long been used in wastewater treatment. The use of natural coagulants/flocculants for water and wastewater treatment has become essential due to the health risks associated with chemical flocculants. Tannin, a natural coagulant, has been suggested as substitute of chemical coagulants. Tannins are present in the leaves, fruits, barks, roots, and wood of trees as a secondary metabolite. Tannin-based coagulants derived from a variety of plant sources have been successfully used in the treatment of water and wastewater. This review summarises the current status and strategies on applications of tannin-based coagulants exploiting the eco-friendly green materials in water and wastewater remediation for the sake of pollution free environment

Focal dermal hypoplasia (Goltz Syndrome): A cross-sectionalstudy from Eastern India

Introduction: Focal dermal hypoplasia (Goltz syndrome), is an extremely rare genetic disorder characterized by distinct skin manifestations and a wide range of abnormalities involving the ocular, dental, skeletal, urinary, gastrointestinal, cardiovascular, and central nervous systems. The objective of the present series is to emphasize the different typical as well as unusual features of this rare syndrome. Methology: This cross-sectional observational study was performed over a period of 8 years in a tertiary care hospital of Eastern India. Consecutive patients with the clinical diagnosis of Goltz syndrome were studied. Results: A total of 8 patients with Goltz syndrome were evaluated. Out of them, one patient was a boy and the rest were girl. The age ranged from 3 days to 9 years. There was no family history. A characteristic Blaschkoid hypo- and hyper-pigmented skin lesions, congenital nodular fat herniation, and skin atrophy were present in all patients. Congenital cutaneous aplasia was present in 50% of the patients. Facial asymmetry and ear deformity (megalopinna and low-set ears) were seen in 37.5% and 12.5% of patients, respectively. Cutaneous telangiectasia was noticed in 37.5% of patients. Freckle- and lentigines-like pigmentation within the hypopigmented macules was found in 25% of patients. Raspberry-like papillomas around mouth were documented in 6 (75%) patients. Dysplastic nail changes with ridging were seen in 7 (87.5%) patients. Genital abnormality in the form of bilateral undescended testes and microphthalmia with aniridia were found in one patient each. Limb defects were present in all patients. Left-sided renal agenesis was found in one patient. The patient also had multiple cortical cysts of the right kidney. Limitations: Genetic testing could not be performed in the present series. Conclusions: Our case series showed a few unusual or extremely rare manifestations such as undescended testes, dermal sinus, kyphoscoliosis, aniridia, unilateral kidney agenesis, and renal cortical cysts among others

Not AvailableMajor nutrient management systems for rice-wheat cropping were compared for their potential to credit organic carbon (C) to the soil, its fractionation into active (very labile, VLc; labile, Lc) and passive (less labile, LLc; non-labile, NLc) pools, and crop yield responses. A ten-year long experiment was used to study effects of: (i) no inputs (Control, O), (ii) 100% inorganic fertilizers (F) compared to reduced fertilizers inputs (55%) supplemented with biomass incorporation from (iii) opportunity legume crop (Vigna radiata) (LE), (iv) green manure (Sesbania aculeata) (GM), (v) farmyard manure (FYM), (vi) wheat stubble (WS), and (vii) rice stubble (RS). Maximum C input to soil (as the percentage of C assimilated in the system) was in GM (36%) followed by RS (34%), WS (33%), LE (24%), and FYM (21%) compared to O (15%) and F (15%). Total C input to soil had a direct effect on soil C stock, soil C fractions (maximum in VLc and LLc), yet the responses in terms of biological yield were controlled by the quality of the biomass (C:N ratio, decomposition, etc.) incorporated. Legume-based biomass inputs accrued most benefits for soil C sequestration and biological productivity.Not Availabl
