BACKGROUND: This study aimed to describe the technique and report our experience with the reconstruction of combined proximal thumb amputations at the metacarpal base level and index finger amputation at the metacarpal level with pollicization and bilateral double toe composite transfer. METHODS: The technique consists of pollicization of the remnant index ray. Then a contralateral composite medial great toe pulp and vascularized second toe proximal interphalangeal joint flap are harvested to reconstruct the metacarpophalangeal joint of the thumb...

Townes-Brocks syndrome is a rare autosomal dominant syndrome characterized by multiple malformations, including thumb anomalies. Thumb hypoplasia poses a specific problem, where a deficient thumb creates a significant handicap in hand function. The treatment goal is enabling pinch and grip activity, and the preferred procedure for a severely hypoplastic thumb is index finger pollicization. We present a case of on-top index pollicization in a 10-year-old, after a partial amputation of a previously syndactylized hypoplastic thumb, with a well-formed first carpometacarpal joint...

Near-infrared vein visualization devices allow for noninvasive identification of superficial veins. During index finger pollicization, preservation of the dorsal veins is important for protecting blood outflow from the digit. Near-infrared vein visualization devices can be used to identify the location of the dorsal veins prior to skin incision, allowing increased confidence during dissection. We describe the use of this device to identify veins during index finger pollicization.

The ARF protein functions as an important sensor of hyper-proliferative stimuli restricting cell proliferation through both p53-dependent and -independent pathways. Although to date the majority of studies on ARF have focused on its anti-proliferative role, few studies have addressed whether ARF may also have pro-survival functions. Here we show for the first time that during the process of adhesion and spreading ARF re-localizes to sites of active actin polymerization and to focal adhesion points where it interacts with the phosphorylated focal adhesion kinase...

Escherichia coli (E. coli) is one of the most commonly adopted indicators for the determination of the microbiological quality in water and treated wastewater. Two main types of methods are used for the enumeration of this faecal indicator: membrane filtration (MF) and enzyme substrate tests. For both types, several substrates based on the β-D-glucuronidase activity have been commercialized. The specificity of this enzyme for E. coli bacteria has generated considerable use of methods that identify the β-D-glucuronidase activity as a definite indication of the presence of E...

Soft tissue metastases of prostate cancer to other sites are extremely rare, and, to our best knowledge, there have been no reports of metastasis to soft tissue of the hand. A 63-year-old man was diagnosed with prostatic cancer. During treatment, bone and soft tissue metastases to the right hand, appearing in the first web space, were observed. The tumor was resected, along with both the first and second metacarpal bones. The thumb was reconstructed by pollicization of the remaining index finger, enabling the patient to use the pollicized thumb for activities of daily living...

The Membrane BioReactor (MBR) is a well-established filtration-based technology for wastewater treatment. Despite the high quality of the effluent produced, one of the main drawbacks of the MBR is membrane fouling. In this context, a possible evolution towards systems having potentially lower installation and operating costs is the Self Forming Dynamic Membrane BioReactor (SFD MBR). Key of this technology is the self-formation of a biological filtering layer on a support of inert material. In this work, a lab-scale aerobic SFD MBR equipped with a nylon mesh was operated at approximately 95Lm(-2)h(-1)...

The thumb plays an integral role in hand function. Traumatic amputation results in significant morbidity. With loss of the thumb, up to a 40% reduction in hand function may result. Thumb replantation must be attempted when possible. The goals of thumb reconstruction are to replicate normal function as closely as possible, minimize donor site morbidity, and expedite recovery. In the setting of a mutilated hand, the status of the remaining digits must be carefully assessed. Toe transfers, osteoplastic thumb reconstruction, and pollicization are commonly used...

Congenital thumb hypoplasia is a radial deficiency occurring in the form of sole dysplasia or in combination with additional aberrations. Thumb hypoplasia can be categorised into 5 grades ranging from mild deformity to complete absence of the thumb. Thumb hypoplasia leads to a disturbance of grip function depending on its severity. The choice of treatment is based on the degree of thumb hypoplasia. For hypoplasia greater than grade 3B, restoration of the thumb using pollicization of the index finger is the treatment of choice...

PURPOSE: To evaluate outcome and function of the reconstructed basilar thumb joint after index finger pollicization in patients presenting congenital thumb deficiency. METHODS: Plain radiographs and 4-dimensional dynamic volume computed tomography scan were used to evaluate the outcome of 23 pollicizations performed on 14 children between 1996 and 2009. The mean follow-up was 8 years. Patients performed continuous movements of thumb opposition during the imaging studies...

Blood supply to the index finger is maintained through volar (palmar arch) and dorsal (intermetacarpal arteries) vascular networks. In traditional index finger pollicization, blood supply is maintained on the volar palmar arch. In case of index finger loss at the metacarpophalangeal joint, remaining length of the second metacarpal is often not used for pollicization because the arc of rotation is limited on digital arteries. In this report, we present a surgical technique for the transfer of the index metacarpal to the thumb on the dorsal vascular network...

The interaction between the enteric microbiota and intestinal cells often involves signal molecules that affect both microbial behaviour and host responses. Examples of such signal molecules are the molecules secreted by bacteria that induce quorum sensing mechanisms in the producing microorganism and signal transduction pathways in the host cells. The pentapeptide competence and sporulation factor (CSF) of Bacillus subtilis is a well characterized quorum sensing factor that controls competence and spore formation in the producing bacterium and induces cytoprotective heat shock proteins in intestinal epithelial cells...

INTRODUCTION: Nager syndrome is a rare condition characterized by craniofacial and upper limb abnormalities. It is commonly mistaken for Treacher Collins syndrome, with which it shares the same craniofacial phenotype. However, patients with Treacher Collins do not exhibit hand anomalies, which are seen in patients with Nager syndrome. This paper reviews the multidisciplinary management of patients with Nager syndrome who were treated at the Australian Craniofacial Unit, Adelaide and the Erasmus Medical Centre, Rotterdam...

Y-box binding protein 1 (YBX-1 or YB-1) is an oncoprotein that promotes replicative immortality, tumor cell invasion and metastasis. The increase in the abundance of YB-1 in the cell or YB-1 translocation from the cytoplasm to the nucleus is characteristic of malignant cell growth. We have previously reported that ΔNp63α, a transcription factor that is known to play a pivotal role in keratinocyte proliferation and differentiation, promotes YB-1 nuclear accumulation. Here, we show that YB-1 is highly expressed in proliferating keratinocytes and is down-regulated during keratinocyte differentiation...

In biological wastewater treatments, microbial populations of the so-called activated sludge work together in the abatement of pollutants. In this work, the metabolic behavior of the biomass of a lab-scale plant treating industrial pharmaceutical wastewater was investigated through a metaproteomic approach. The complete treatment process included a membrane biological reactor (MBR) coupled with an advanced oxidation process (AOP) for partial breakdown of non-biodegradable molecules. Proteins from biomass samples collected pre- and post-AOP application were investigated by two-dimensional gel electrophoresis (2DE), mass spectrometry (MS), and finally identified by database search...

The observation and investigation of nonlinear effects in catalytic reactions provides valuable mechanistic insight. However, the applicability of this method was, until now, limited to molecules possessing chirality and therefore to asymmetric synthesis. The concept of nonlinear effects is expanded to catalytic reactions beyond asymmetric catalysis by using derivatives instead of enantiomers and by considering rates instead of enantiomeric excess. Additionally, its systematic application to investigate the mechanism of catalytic reactions is presented...

BACKGROUND: TAS-102 is an oral fluoropyrimidine prodrug composed of trifluridine (FTD) and tipiracil hydrochloride (TPI) in a 1:0.5 ratio. FTD is a thymidine analog, and it is degraded by thymidine phosphorylase (TP) to the inactive trifluoromethyluracil (FTY) metabolite. TPI inhibits degradation of FTD by TP, increasing systemic exposure to FTD. METHODS: Patients with advanced solid tumors (6 M/2 F; median age 58 years; PS 0-1) were enrolled on this study. Patients in group A (N = 4) received 60 mg TAS-102 with 200 nCi [(14)C]-FTD, while patients in group B (N = 4) received 60 mg TAS-102 with 1000 nCi [(14)C]-TPI orally...

PURPOSE: Mirror hand or ulnar dimelia is a rare and poorly studied congenital anomaly of the upper extremity. Understanding of its anatomy is limited by the rarity of the deformity and the variability in presentation. We present the case of an 80-year-old female donor with an incidental finding of mirror hand. METHODS: Medical history indicated no record of any surgical procedures or interventions to the right upper extremity suggesting that the donor had lived an independent life without the need for prosthetic aids...

Patients with mild pulmonary hypoplasia typically use to have minimal respiratory symptoms. Nonetheless, other associated anomalies such as cardiac, gastrointestinal, genitourinary, or skeletal defects may be seen. We report the case of a 17-year-old male patient with hypoplastic right lung with secondary cardiac dextroposition, an ostium secundum atrial septal defect, a hypoplastic right pulmonary artery arising from the posterior wall of the left pulmonary artery with a retrocava course, vertebral bone fusion and pollicization due to right congenital thumb absence...
