RESUMEN

Thumb tip injuries constitute one of the most common hand injuries. There are various reconstructive options for thumb tip injuries. We present our series of thumb tip injuries reconstructed using Elliot's modification of the Moberg flap, which provides like-for-like tissue. We also present our flap improvisation, which can be useful in the armamentarium of plastic surgeons. Background Moberg described the advancement flap for thumb defects in 1964, which was modified by O'Brien in which the proximal part of the flap is incised and advanced. Although it is a popular flap, it has the disadvantage of interphalangeal (IP) joint flexion deformity. Among the various modifications of the Moberg flap, Elliot's flap provided more tissue with minimal donor site morbidity and no usage of skin grafts or first web skin. Methods We retrospectively analyzed the patients who underwent reconstruction of thumb defects by Elliot's modified Moberg's flap. The size of the defect, etiology, and IP joint movement were analyzed. Two patients underwent our improvised flap where a daughter flap was elevated within Elliot's flap. Results Between January 2021 and September 2023, 12 patients underwent reconstruction by Elliot's flap. All flaps settled well. There was no IP joint deformity. Two patients had scar hypertrophy that was managed conservatively. Conclusion Elliot's modification of the Moberg flap is a very useful but underutilized flap for thumb tip injuries that provides like tissue with sensation and with little donor site morbidity. It can be used for thumb tip defects of up to 3 cm . It is possible to incorporate a second V-Y flap in patients for whom additional movement is required for tension-free closure.

RESUMEN

Background Palmaris longus (PL) is a short-bellied muscle with a long tendon that merges with the palmar aponeurosis. It is supplied by the median nerve and acts as a tensor of the palmar aponeurosis and flexes the wrist. This tendon is commonly used for tendon transfers and as a donor for tendon graft. There are numerous clinical tests to detect the presence of PL like Schaeffer's test, Thompson's test, Mishra's test I, Mishra's test II, Pushpakumar's "two-finger sign" method, and AIIMS test. The principle of all these tests is to make the tendon prominent by eliciting its flexor action and then its identification by inspection and palpation. Objectives The tests that are consistently easy to perform with good understandability would be easy to explain to the general population (patients). The aim of our study is to find out the accuracy and easy comprehensibility of various tests using compulsive postures for detecting PL tendon clinically. Materials and Methods This is a prospective study on 137 participants. All the patients were subjected to six clinical tests to detect the presence or absence of PL tendon. The results were recorded for both hands by a single observer. Results Of the 137 participants, 75 were males (54.74%) and 62 were females (45.26%). The mean age was 21 years. The AIIMS test showed the maximum number of tendons, that is, 113 (82.4%) in the right hand and 108 (78.8%) in the left hand. In view of the ability to comprehend the tests, 119 (86.9%) subjects understood Schaeffer's test very easily. Conclusion According to this study, the AIIMS test best demonstrates the PL tendon, and Schaeffer's test was the test most easily understood by the subjects.

RESUMEN

The earlobe is an important anatomical structure that has a significant role in aesthesis. An absent ear lobule may be congenital or acquired due to the result of trauma, infection or malignancy. Its surgical repair places a challenge due to the difficulty of obtaining a natural-appearing and durable outcome. Many procedures have been described for reconstruction including the Gavello and Zenteno Alanis techniques. We have described a new method which is single staged, easy to perform and aesthetically acceptable.

RESUMEN

A balance between surgical access and aesthetics, with lesser post-op sequelae, is inevitable in the management of facial fractures. Even though various approaches are widely practised, further modifications and revisions are encouraged for better outcomes. We performed a prospective cross-sectional study on 30 patients with Zygomatico-Maxillary Complex (ZMC) fracture with inferior orbital rim involvement. Surgical management was performed using subtarsal (Group A) or laterocaudal (Group B) approach, during which the time taken to expose fracture and the ease of access was documented. Scar evaluation was performed using SCAR Scale on the 15th day and after one-month and three-month follow-up, and the post-op complications including ectropion, infections, edema, etc., were documented. There was a significant reduction in the time taken (p < 0.001) in group B than in group A. The ease of access did not demonstrate any significant difference. The SCAR scale score was significantly reduced at 3rd-month follow-up in group B compared to the other group (p = 0.009). Laterocaudal approach demonstrated lesser time-taken and better access to the inferolateral rim, with superior aesthetics and fewer complications. This approach can be employed in clinical practice, especially with inferolateral rim involvement in ZMC fractures.

RESUMEN

Botulinum toxin type A (BoNT-A) has been recommended in various neurological disorders as a useful tool for alleviating dystonia. In Wilson disease (WD) patients with dystonia, BoNT-A injection can be used as a treatment modality when conventional treatment is ineffective for alleviating symptoms. The purpose of this study was to thoroughly evaluate the efficacy of BoNT-A injection in treating WD complicated by lower extremity dystonia. The efficacy of these injections was assessed by clinical scales, surface electromyography (EMG), and gait analysis. A comparative analysis of all gait parameters, EMG parameters, and clinical scales revealed a significant increase in velocity, decrease in integrated EMG (iEMG), and improvement in modified Ashworth scale (MAS), Burke Fahn Marsden (BFM), and activities of daily living (ADL) scores (all P < 0.05). Overall, our findings indicated that BoNT-A injection led to marked relief of symptoms in patients with WD with lower extremity dystonia.

RESUMEN

Objective: The purpose of this study was to investigate attentional network functional characteristics in patients with cervical dystonia (CD). Methods: A total of 29 patients with CD and 26 healthy controls (HCs) were recruited. All subjects participated in the study and underwent the Attention Network Test (ANT), which evaluated the efficiencies of three independent attention networks (alerting, orienting, and executive control), as well as reaction time (RT) and accuracy. Results: Significant differences between CD patients (9.86 ± 27.95 ms) and HCs (33.62 ± 23.41 ms) were observed in the alerting network (t = -3.40, p < 0.05). In contrast, the orienting network (t = 0.26, p = 0.79), executive control network (Z = -0.55, p = 0.58), total mean reaction time (t = -2.6, p = 0.79), and total accuracy rate (Z = -1.67, p = 0.09) showed no significant differences between the two groups. Conclusion: Patients with CD showed a significant deficit in the alerting network. However, they did not show any deficits in the orienting or executive control network. In addition, the alerting, orienting, and executive control network functions of CD patients were all affected by the severity of torticollis, especially the alerting network function.

RESUMEN

Introduction: The genus Morus is well known for its medicinal benefits from time immemorial. The present work reported the health-promoting properties of the biologically active molecules present in different species of the genus Morus. Methods: Different solvent extracts of the three plant species of Morus were investigated initially for their antioxidant effects, followed by in vitro anticancer studies against MCF7 and 3T3 cell lines along with their bioactive isolates viz. cathafuran-B, moracin-M, and Ursolic acid. Further, in silico docking studies were performed for the isolated compounds to predict their probable mode of interaction with P38Map Kinase. Results: The results indicated that all three species under study possessed remarkable antioxidant effects which are supported by a linear and positive correlation between different antioxidant activities. The in vitro cell antiproliferative test indicated that the cell survivability decreased with an increase in the concentration of extracts and compounds. Among the extracts, M. laevigata methanol extract showed 21.57, 6.27% of cell survival against MCF7 and 3T3 cell lines at 800 µg/mL concentration while among the isolated compounds, ursolic acid showed 8.46, 17.58% of cell survival at 200 µg/mL concentration. Among the three compounds docked, ursolic acid showed greater binding affinity towards the target protein in terms of its binding energy (-9.97 kJ/mol) compared to Cathafuran B (-8.35 kJ/mol) and Moracin M (-6.91 kJ/mol). Conclusion: The study generated interesting results in terms of health benefits of Morus species by documenting their antioxidant and anticancer activities, thereby validating the folk claims of therapeutic benefits of mulberry.

RESUMEN

BACKGROUND: Craniosynostosis correction surgery is a complex procedure, which involves complete dismantling and reassembly of the cranial vault components. The traditional planning method for these surgeries results in increased intra-operative time owing to its highly subjective nature. The advent of virtual surgical planning (VSP) platform has lead to a greater pre-operative insight and precision outcome in calvarial remodeling surgeries. The purpose of this paper is to evaluate intra-operative time and blood loss difference as a measure of surgical efficiency between VSP based template guided Anterior Cranial Vault Reconstruction (ACVR) with Fronto-Orbital Unit Advancement (FOUA) and the traditional surgeries. METHODS: Data were collected from patients who underwent ACVR with FOUA in our unit. Patients were divided into 2 groups, Template Fronto-Orbital Unit (TFOU) group and Non-template Fronto-Orbital Unit (NFOU) group. In TFOU group, Virtual planning along with fabrication of Template guide was carried out. Patients undergoing ACVR using traditional techniques were categorized as NFOU group. A comparative prospective analysis was carried out in terms of Intra-operative time duration and blood loss. Student 't' test was used to compare the means of the 2 groups. RESULTS: A total of 10 patients were included in the present study. There were 5 control (NFOU) and 5 TFOU cases. There was a significant decrease in the operating time in TFOU group compared to the NFOU group. TFOU group also showed reduced intra-operative bleed compared to the NFOU group. CONCLUSION: Virtual surgical planning (VSP) and 3D modeling with prefabricated template guide augurs reliable outcomes and portends the possibility of lesser intra-operative time. It is a valuable tool, which offers enormous benefits in terms of precise pre-surgical planning with predictive results.

RESUMEN

Recent studies have revealed that long non-coding RNAs (lncRNAs) involve in the progression of oral squamous cell carcinoma (OSCC). These lncRNAs have emerged as biomarkers or therapeutic targets for OSCC. We here aimed to investigate the role of lncRNA LINC01315 in OSCC and the related mechanisms. LINC01315 and DLG3 were determined to be poorly expressed while microRNA-211 (miR-211) was highly expressed in OSCC tissues and cells using RT-qPCR and western blot analysis. Based on the results obtained from dual-luciferase reporter gene, RIP, and FISH assays, LINC01315 was found to upregulate DLG3 expression by competitively binding to miR-211. Upon altering the expression of LINC01315, and/or miR-211 in OSCC cells with shRNA, mimic, or an inhibitor, we assessed their effects on OSCC cell proliferation, migration, invasion, and apoptosis. LINC01315 knockdown enhanced OSCC cell proliferation, migration and invasion, but dampened their apoptosis, all of which could be reversed by miR-211 inhibition. Elevation of DLG3, a target gene of miR-211, activated the Hippo signaling pathway, whereby suppressing OSCC progression in vitro. Finally, their roles in tumor growth were validated in vivo. These findings suggest that LINC01315 elevates DLG3 expression by competitively binding to miR-211, thereby suppressing OSCC progression.

RESUMEN

In the current study, we used 9.4-tesla magnetic resonance imaging (9.4T MRI) and inductively coupled plasma mass spectrometry (ICP-MS) to investigate the distribution of copper in the brain samples of a murine model of Wilson's disease (WD) following penicillamine (PCA) treatment. We also evaluated if the distribution of copper in the brain samples of mice was correlated with behavioral symptoms. Results from the behavioral experiments showed that 7 days of PCA treatment decreased the total distance traveled in the open field and the number of rearing and climbing instances among the toxic milk (TX) mice as compared with model group. We also observed that the open arm ratio in the elevated plus-maze (EPM) was reduced, escape latency in the Barnes maze test was increased, and avoidance in the open field was enhanced in TX mice following 14 days of PCA treatment as compared with those in untreated TX mice. We found that PCA treatment for 21-28 days improved the cognitive abilities, exploratory behavior, and movement behavior of TX mice. The PCA-treated mice also exhibited varying degrees of magnetic susceptibilities in the cortex, corpus striatum, hippocampus, and amygdaloid nucleus across the treatment period. Low copper concentrations were found in all of the analyzed brain regions of PCA-treated mice after 21-28 days as compared with the model group (P < 0.05). However, copper concentrations were increased in the primary motor cortex and cerebellum at 7 days post-PCA treatment as compared with those in the model group (P < 0.05). After 14 days of PCA treatment, the copper concentrations in the sensorimotor cortex, corpus striatum, hippocampus, and amygdaloid nucleus were higher than those detected without treatment. The results from a Pearson's correlation analysis revealed that there was a significant (P < 0.05) correlation between copper concentrations and magnetic susceptibility in all of the brain regions that were analyzed. Therefore, our results indicate that copper concentration and magnetic susceptibility are associated with alterations in mood-related behavior, recognition memory, and movement behaviors in TX mice that are treated with PCA. The redistribution of copper in the TX mouse brain during PCA treatment may aggravate changes in behavioral performance.

RESUMEN

In this paper, some quality problems of mineral medicine Calamina and calcined Calamina have been discussed after determination and analysis of the quality parameters of a large number of market samples, and the countermeasures are put forward. According to the XRD results, as well as the results of tests included in Chinese Pharmacopoeia(2015 edition), the authenticity of Calamina and calcined Calamina samples were identified. The content of zinc oxide in samples were determined by the method of determination in Chinese Pharmacopoeia. Individually, inductively coupled plasma mass spectrometry(ICP-MS), inductively coupled plasma atomic emission spectrometry(ICP-AES) and atomic fluorescence spectrometry(AFS) methods were used for the determination of impurity elements and harmful elements in Calamina and calcined Calamina samples. Four kinds of impurity elements of magnesium(Mg), iron(Fe), aluminum(Al), calcium(Ca) and five harmful elements such as lead(Pb), cadmium(Cd), arsenic(As), copper(Cu), mercury(Hg) were measured. The study showed that: ① Fake Calamina products on the market were overflowing; ② The mineral origin of the mainstream Calamina in the market is inconsistent with that stipulated in Chinese Pharmacopoeia(2015 edition); ③ The contents of harmful elements Pb and Cd in Calamina and calcined Calamina are generally higher, while the contents of harmful elements As and Cu in some inferior Calaminae are higher; ④ Parts of calcined Calamina were improperly or inadequately processed. In view of these quality problems, the countermeasures are put forward as follows: ① It is suggested that hydrozincite should be approved as the mineral source of Calamina, and be included by Chinese Pharmacopoeia; ② Strengthen the research on the specificity of Calamina identification methods to improve the quality control level; ③ Strengthen the research on the processing of Calamina, and formulate the limit standards for the content of Pb and Cd in Calamina; ④ Carry out research on the artificial synthesis of Calamina and calcined Calamina, in order to cope with the current shortage of Calamina resources and ensure the sustainable development of Calamina medicinal materials.

RESUMEN

A combination of LC-MS technology and activity evaluation was used to identify the antipyretic ingredients in rhubarb. The rat model of fever was established with dried yeast and then was administered ethanol extract and different polar fractions of rhubarb. Next, the anal temperature of these rats was measured and recorded at 0.5, 1, 2, 3, 4 and 5 h after administration, and the inhibition rate of each part on the rise of body temperature was calculated. The inhibition rate is higher and the antipyretic effect is better. The chemical composition of the effective fraction was analyzed with UPLC-ESI-Orbitrap-MS/MS technology. Compared with the model group, the increase of body temperature of ethanol extract group all reduced at each measurement time especially after 3 h, and the inhibition rate were 38.7%(P<0.05), 78.2%(P<0.01) and 72.4%(P<0.01) at 3 h, 4 h, and 5 h after administration, respectively. Both n-butanol and water fraction showed some antipyretic activity in the early stage, with the inhibition rate of 28.1%(P<0.01) and 24.9%(P<0.05) at 1 h after administration, respectively, while other fractions were not active. Thirty-three and twelve compounds were identified from n-butanol and water fraction by LC-MS/MS analysis, respectively, including ten tannins, fifteen anthraquinone glycosides, four anthrone glycosides, one phenolic glycoside, one naphthaline derivative, one anthraquinone and one sucrose. These results revealed that rhubarb had antipyretic activity on rats, and tannin and anthraquinone glycosides were the main active ingredients inside.

RESUMEN

RATIONALE: Both Wilson disease (WD) and Oculocutaneous Albinism (OCA) are rare autosomal recessive disorders that are caused by mutations on chromosome 13 and chromosome 11, respectively. Here, we report on a patient with coexisting WD and OCA, initially presenting episodes of tremors. PATIENT CONCERNS: WD is a disorder of copper metabolism. The main sites of copper accumulation are the liver and the brain, resulting in hepatic symptoms. OCA is a disorder of melanin biosynthesis, characterized by a generalized reduction in pigmentation of the eyes (oculo-), skin (-cutaneous), and hair. DIAGNOSIS: The diagnosis of WD was confirmed by neurological symptoms, metabolism tests, and MRI scans. Interestingly, the patient also had very light skin color, blond hair and eyebrows, and dark brown eyelashes and irises. Because the association of dermatologic signs in WD has rarely been reported, OCA was highly suspected based on these clinical findings. Genetic analysis was subsequently conducted, and the results revealed the p. (Arg778Leu) mutation in 1 allele and the p. (Asn1270Ser) mutation in the other allele of the ATP7B gene, confirming the diagnosis of WD; the p. (D456fs) mutation in 1 allele and the p. (R299H) mutation in the other allele of the TYR gene, confirming the diagnosis of OCA. The family history was positive for WD with a 14-year-old younger brother also being diagnosed with it. Her parents are negative for OCA and WD. INTERVENTIONS: Sodium dimercaptopropanesulfonate (DMPS) was given during hospitalization. D-penicillamine and zinc sulfate treatment was initiated after discharge for long-term control. OUTCOMES: Postural and intention tremor disappeared, and other symptoms and signs markedly improved after treatment. LESSONS: In this study, we reported on the first case of a child who simultaneously presented WD and OCA, bringing up the possibility of a presumable link between these 2 rare diseases.

RESUMEN

Eccrine acrospiroma are benign skin tumours of sweat duct origin. They usually present as small solid or cystic lesions which are confused clinically with other solid or cystic lesions. These are generally benign lesions with few reports of malignant transformation. Here, we report a case of a middle aged female presenting with a swelling of the dorsum of left first web space which was histopathologically diagnosed as an eccrine acrospiroma, which was managed with surgical excision and covered with a regional flap. This case is presented due to the large size of the lesion in the hand.

RESUMEN

AIM: To investigate the effects of heme oxygenase-1 (HO-1)-modified bone marrow mesenchymal stem cells (BMMSCs) on the microcirculation and energy metabolism of hepatic sinusoids following reduced-size liver transplantation (RLT) in a rat model. METHODS: BMMSCs were isolated and cultured in vitro using an adherent method, and then transduced with HO-1-bearing recombinant adenovirus to construct HO-1/BMMSCs. A rat acute rejection model following 50% RLT was established using a two-cuff technique. Recipients were divided into three groups based on the treatment received: normal saline (NS), BMMSCs and HO-1/BMMSCs. Liver function was examined at six time points. The levels of endothelin-1 (ET-1), endothelial nitric-oxide synthase (eNOS), inducible nitric-oxide synthase (iNOS), nitric oxide (NO), and hyaluronic acid (HA) were detected using an enzyme-linked immunosorbent assay. The portal vein pressure (PVP) was detected by Power Lab ML880. The expressions of ET-1, iNOS, eNOS, and von Willebrand factor (vWF) protein in the transplanted liver were detected using immunohistochemistry and Western blotting. ATPase in the transplanted liver was detected by chemical colorimetry, and the ultrastructural changes were observed under a transmission electron microscope. RESULTS: HO-1/BMMSCs could alleviate the pathological changes and rejection activity index of the transplanted liver, and improve the liver function of rats following 50% RLT, with statistically significant differences compared with those of the NS group and BMMSCs group (P < 0.05). In term of the microcirculation of hepatic sinusoids: The PVP on POD7 decreased significantly in the HO-1/BMMSCs and BMMSCs groups compared with that of the NS group (P < 0.01); HO-1/BMMSCs could inhibit the expressions of ET-1 and iNOS, increase the expressions of eNOS and inhibit amounts of NO production, and maintain the equilibrium of ET-1/NO (P < 0.05); and HO-1/BMMSCs increased the expression of vWF in hepatic sinusoidal endothelial cells (SECs), and promoted the degradation of HA, compared with those of the NS group and BMMSCs group (P < 0.05). In term of the energy metabolism of the transplanted liver, HO-1/BMMSCs repaired the damaged mitochondria, and improved the activity of mitochondrial aspartate aminotransferase (ASTm) and ATPase, compared with the other two groups (P <0.05). CONCLUSION: HO-1/BMMSCs can improve the microcirculation of hepatic sinusoids significantly, and recover the energy metabolism of damaged hepatocytes in rats following RLT, thus protecting the transplanted liver.

RESUMEN

The purpose of this article is to identify Daphne genkwa and its adulterants, Wikstroemia chamaedaphne, according to the morphological and microstructure characteristics of their stem and foliage. The root of D.genkwa was studied simultaneously. The results indicated that the crude drug and processed pieces of Genkwa Ramulus were mainly composed of stems and branches where obvious opposite petiole scars and branch marks were able to be seen on their nodes. Otherwise, foliage or peduncles generally couldn't be found. Moreover, the fine silver flocculent fibers could be observed in the bark of fracture surface. The adulterants were the plant segments which were composed of stems, foliage and peduncles with spikelet-pedicel scars. There existed microstructures differences between Genkwa Ramulus and its adulterants. In the former, single thick lignified phloem fibers were interspersed in the stem phloem of the transverse section with very thick wall and unicellular non-glandular hairs could be observed on the lower epidermis of foliage. Nevertheless, in the latter, there was no thick lignified phloem fibers in cross section of stem phloem, the outer wall of epidermal cells of foliage hadthick cuticles and no non-glandular hairs in lower epidermis of foliage. The results can be used for the identification and the quality standard of the crude drug and processed pieces of D.genkwa.The characteristics of the microstructures and the transverse section can be used to identify the radix D.genkwa.

RESUMEN

BACKGROUND: Fingertip injuries that are complicated by pulp loss, bone or tendon exposure will need a flap cover. Cross finger flap is commonly used to cover such defects. However, patients are apprehensive about injuring the uninjured finger as a donor site. Reverse homodigital artery flap (RHAF) can provide reliable vascularised cover to such defects. AIMS: This study aims to assess the functional and aesthetic outcomes along with the patient satisfaction of RHAFs done for fingertip defects. MATERIALS AND METHODS: RHAFs done in 18 patients operated between August 2015 and October 2016 were retrospectively analysed on flap survival, sensory recovery, range of movements, hypersensitivity, cold intolerance, flexion contracture and donor site morbidity. RESULTS: Seventeen of the 18 flaps done survived completely. One flap had partial necrosis of 3 mm that healed conservatively. Middle finger of the right hand was the most commonly injured finger. Touch, pain and pressure sensations recovered in 8-12 weeks. Two-point discrimination was 4.5 mm at 6 months. The deficit of 5° s was present at distal interphalangeal joint during active flexion at 6 months. Cold intolerance and flexion contracture were not seen and 2 instances of hypersensitivity at 2 months got cured conservatively after 4 months. Overall satisfaction of patients was 8/10. CONCLUSION: RHAF provides single staged well-vascularised cover for fingertip injuries with good sensory recovery without damaging the adjacent uninjured finger. Hence, it can be a reliable flap for fingertip reconstruction in selected cases.

RESUMEN

Superficial acral fibromyxoma (SAF) is a rare lesion initially described by Fetsch as a tumour with histological and immunohistochemical features located at acral sites. It is a benign slow-growing soft tissue lesion occurring in males. Patients generally look for late medical help as it is generally painless. The lesion consists of spindled and stellate-shaped cells in the myxocollagenous stroma with immunohistochemical positivity for CD34, CD99 and vimentin. Treatment is surgical excision with regular follow-up. Here we present a case of a superficial acral fibromyxoma of the left index finger which radiologically showed features of vascular anomaly on MRI. The lesion was surgically excised and histopathology revealed features suggestive of superficial fibromyxoma with positive immunohistochemistry for CD34 and negative for S-100.
