Published: February 2025

A new genus, (Mesostigmata: Uropodina: Trematuridae), with as its type species, is described, based on a female, males, and deutonymphs collected in soil samples from the Seychelle Islands. The new genus belongs to the family Trematuridae based on the shape of the corniculi, gnathosomal setae, tritosternum and chelicerae. Members of the new genus bear a preanal suture on the ventral shield, two pairs or more pairs of wide, robust and sword-like setae on the caudal part of the dorsal shield, very dense setation on the caudal area of the marginal shield and an incision on the anterior part of the dorsal shield. These characters are missing in the other genera of Trematuridae. Two previously described species ( Hirmatsu & Hirschmann, 1988 and Hirschmann & Hirmatsu, 1990) from the Philippines are transferred to the new genus, as (Hirmatsu & Hirschmann, 1988), and (Hirschmann & Hirmatsu, 1990), The new species differs from its congeners in the sculptural pattern of the female genital shield and in the shape of the robust and sword-like setae on the caudal area of the dorsal shield.

Department of Anesthesiology, West China Hospital, Sichuan University, Chengdu, China.

Aims: Neuropathic pain (NP) is a debilitating condition characterized by chronic pain resulting from nerve damage or lesion. Despite the ongoing efforts of clinically defining NP, its distinctive mechanisms that lead to various NP phenotypes remain unresolved.

Methods: Using a spared nerve injury (SNI) model, we investigated the mechanisms underlying the development of NP caused by injury in the peripheral nerves.

Objective: CSF leaks are a significant source of patient morbidity following intradural spine surgeries. Watertight dural closure is crucial during these procedures to minimize the risk of a CSF leak. This study reports postoperative outcomes and changes in patient management after switching to penetrating titanium clips for dural closure in a large cohort of pediatric patients receiving a tethered cord release (TCR) or a selective dorsal rhizotomy (SDR).
