BACKGROUND: In cases where autologous bone graft reconstruction is not possible (such as comminuted fractures, bone graft reabsorption, or infection) and the use of synthetic material is required, polymethylmethacrylate (PMMA) use is a safe and efficient solution. Studies comparing the incidence of postoperative complications between autologous and synthetic cranioplasty are heterogeneous, not allowing a conclusion of which is the best material for skull defects reconstruction. Current medical literature lacks prospective well-delineated studies with long-term follow-up that analyze the impact of antibiotic use in PMMA cranial reconstruction of moderate and large defects...

AIMS OF THE STUDY: Fingertip injuries can be treated in different ways, including shortening with primary closure, skin graft, and local or distant flaps. Several local flaps for the reconstruction of the amputated fingertip were described. We present our experience with a new concept of homodigital adipofascial reverse flap that avoids the second surgical stage and allows a complete and anatomically perfect reconstruction of nail bed, with preservation of the nail lamina. MATERIALS AND METHODS: Between March 2014 and February 2015, five patients with digital amputations (distally to the nail matrix) were treated using the Fenestrated Adipofascial Reverse (F...

REVIEW
Tara L Braun, Jeffrey G Trost, William C Pederson
Syndactyly is one of the most common congenital hand anomalies treated by pediatric plastic surgeons. Established principles of syndactyly separation dictate the timing and order of syndactyly release, with the goals of surgery being the creation of an anatomically normal webspace, tension-free closure of soft tissue, and return of function to the fingers. Numerous surgical methods have been described, many of which involve the use of local flaps to reconstruct the commissure and full-thickness skin grafts for coverage of raw areas...

Amputation by crush injuries generally represents a contraindication for replantation, and especially when the lesion is caused by the summation of multiple concomitant traumatic mechanisms. We present the case of a 22 year- old female who arrived in our service with a crush/torsion amputation of all long fingers at the metacarpo-phalangeal level of the right hand. After the unsuccessful attempt of replantation, the functional reconstruction of the hand was achieved by using a double free flap transfer: anterolateral thigh perforator flap (ALT) and digital block transfer of second and third toes...

BACKGROUNDS: Various flaps elevated from the palm have been widely used for finger and hand reconstruction. Recently, perforator-based free flaps or venous free flaps have received popularity due to several advantages. The cutaneous venous system has been chosen as the circulatory outlet when designing and harvesting the flap from the palmer area due to the small size and thin nature of the flap. However, there have been few descriptions about the anatomy of the palmar cutaneous veins...

A new species of semi-terrestrial crab of the family Potamidae, Rathbunamon chumomrayense sp. nov. is described from Chu Mom Ray National Park, the Central Highlands of Vietnam. The new species can be distinguished from R. lacunifer (Rathbun, 1904), the only other species in the genus, by a suite of characters, including the slightly more rugose anterolateral regions, confluent epigastric and postorbital cristae that are sinuous, less convex anterolateral margins, relatively shorter fingers of the chelipeds, and the terminal segment of the male first gonopod being slightly curved outwards, with narrower dorsal flap...

BACKGROUND: In the literature, there is a lack of a consensus about the occurrence of the compartment syndrome due to the snake bites. There are different concepts for the surgical treatment of the threshold value of the chamber pressure. There are many different classifications and assessment criteria for the snakebites. PURPOSE: There is not any appropriate classification in order to the assessment of extremity snake bites while making a decision for fasciotomy...

Skin coverage in hand reconstruction is a challenging and vast chapter in hand surgery; covering every aspect of it in a report is simply not feasible. Therefore, this report focuses on a few specific topics. The coverage of anatomical regions like the fingertips is common ground for hand surgeons worldwide, but in the last 10 years, various refinements have been published in order to optimize the reconstruction of this organ. Nevertheless, in many emergency departments, the amputation of badly injured fingertips, including the thumb, remains the preferred treatment...

OBJECTIVE: Many skin flaps have been described for fingertip reconstruction; however, they have not been compared histologically. The aim of this study is to compare the histological features of common insensate flaps that are used for fingertip reconstruction. METHOD: Skin from fingertips and common flap donor sites on the hand and forearm of cadavers were harvested. This study investigated four histological characteristics, namely thickness of the epidermis and dermis; the ratio of collagen to elastic fibres (C/E ratio) in subdermal tissues, and distribution densities of Merkel cells and Meissner's corpuscles...

Occupational injuries to digits due to hydrofluoric acid (HFA) are frequently encountered. They have distinctive features, including intense pain, progressive tissue necrosis, and possible bone erosion. To minimize tissue damage, it is of great importance to execute prudent preoperative assessment and determine the correct surgical modality to reconstruct and maintain the function of the hand. However, proper protocols for fingers have not been presented in previous studies. Eight cases with HFA burn to digits were presented to the emergency room...

: Unsuccessful reconstruction of injured fingers can lead to poor outcomes. The aim of this article was to investigate the clinical application of the radial artery superficial palmar branch flap for soft-tissue reconstruction of the finger. We treated 125 patients with various finger injuries who underwent free radial artery superficial palmar branch flap reconstruction between October 2010 and March 2015. There were 46 distal finger injuries, 25 distal finger amputation following failed replantation and 54 palmar digital injuries with tendon, bone or joint exposure requiring soft-tissue reconstruction...

In this report we present a case of large sized volar surface defect of a digit reconstructed by hypothenar perforator free flap coverage. A 57-year-old male patient presented with a 5 × 2 cm sized avulsive injury on his left little finger involving near total loss of the volar surface. The perforator arteries of the hypothenar area were identified around 5-15% on the x-axis and 25-50% on the y-axis (y-axis: a line from the pisiform base to the metacarpophalangeal joint, x-axis: a line perpendicular to the y-axis...

The structure-specific nuclease human flap endonuclease-1 (hFEN1) plays a key role in DNA replication and repair and may be of interest as an oncology target. We present the crystal structure of inhibitor-bound hFEN1, which shows a cyclic N-hydroxyurea bound in the active site coordinated to two magnesium ions. Three such compounds had similar IC50 values but differed subtly in mode of action. One had comparable affinity for protein and protein-substrate complex and prevented reaction by binding to active site catalytic metal ions, blocking the necessary unpairing of substrate DNA...
