n the northeastern part of the Himalaya. The automation of this method for future operational usage is also suggested.
In conservative early onset scoliosis treatment, interest in bracing is growing because repeated general anaesthesia (required by casting) has been questioned for possible brain damages. We aimed to check the results in the medium term of bracing, comparing idiopathic (IIS) to secondary (SIS) infantile scoliosis.
We performed a retrospective study in a consecutive prospective cohort. see more Inclusion criteria were discovery of scoliosis and bracing below age 3; exclusion criteria previous spine surgery, less than three consultations. We considered the following results full (< 20° Cobb) and partial (< 30°) success; hold-up (progression < 5° but curve > 29°); partial (progression > 5°) and full (fusion) failure; statistics ANOVA for repeated measures; linear mixed effect model with Cobb angle (dependent), time and diagnosis (independent) variables.
We included 34 infants (16 IIS and 18 SIS) of age 1·10 ± 0·10 (years·months), 44 ± 17° curves, 27 ± 10° rib vertebral angle difference, average observation 5·05 ± 3·03years. We found progressive improvement of IIS and stability of SIS patients. Six IIS (37.5%) and one SIS (6%) reached brace weaning before puberty with 13 ± 5° (improvement 61 ± 15%, p < 0.001), after 4·11 ± 3·07years of treatment. Three patients were fused, one IIS (6%) and two SIS (11%). Two IIS patients also reached end-of-growth with 18° (start 40° at 1·03years) and 20° (start 32° at 2·12years), respectively.
Bracing shows promising results in the medium term for high-degree IIS, with very few hold-ups (19%) and failures (12%). Conversely, failures prevail for SIS (full 11%), even if the partial failure (39%) is still a time-buying strategy.

Some years later, a role for thiamine deficiency in diabetic neuropathy became evident, and some pilot studies evaluated the putative effects of thiamine supplementation. However, the administration of thiamine and its lipophilic derivative benfotiamine for the treatment of this complication gained consensus only at the end of the '90 s. The first evidence of the beneficial effects of thiamine on microvascular cells involved in diabetic complications dates to 1996 from then on, several papers based on in vitro and animal models have addressed the potential use of this vitamin in counteracting diabetic microangiopathy. A few pilot studies in humans reported beneficial effects of thiamine administration on diabetic nephropathy, but, despite all promising proofs-of-concept, the possible role of thiamine in counteracting development or progression of retinopathy has not been addressed until now. Thiamine is a water-soluble vitamin, rapidly expelled from the body, with no issues of over-dosage or accumulation; unfortunately, it is non-patentable, and neither industry nor independent donors are interested in investing in large-scale randomized controlled clinical trials to investigate its potential in diabetes and its complications. Consequently, science will not be able to disprove a promising hypothesis and, more importantly, diabetic people remain deprived of a possible way to ameliorate their condition."Interphase epichromatin" describes the surface of chromatin located adjacent to the interphase nuclear envelope. It was discovered in 2011 using a bivalent anti-nucleosome antibody (mAb PL2-6), now known to be directed against the nucleosome acidic patch. The molecular structure of interphase epichromatin is unknown, but is thought to be heterochromatic with a high density of "exposed" acidic patches. In the 1960s, transmission electron microscopy of fixed, dehydrated, sectioned, and stained inactive chromatin revealed "unit threads," frequently organized into parallel arrays at the nuclear envelope, which were interpreted as regular helices with ~ 30-nm center-to-center distance. Also observed in certain cell types, the nuclear envelope forms a "sandwich" around a layer of closely packed unit threads (ELCS, envelope-limited chromatin sheets). Discovery of the nucleosome in 1974 led to revised helical models of chromatin. But these models became very controversial and the existence of in situ 30-nm chromatin fibers has been challenged. Development of cryo-electron microscopy (Cryo-EM) gave hope that in situ chromatin fibers, devoid of artifacts, could be structurally defined. Combining a contrast-enhancing phase plate and cryo-electron tomography (Cryo-ET), it is now possible to visualize chromatin in a "close-to-native" situation. ELCS are particularly interesting to study by Cryo-ET. The chromatin sheet appears to have two layers of ~ 30-nm chromatin fibers arranged in a criss-crossed pattern. The chromatin in ELCS is continuous with adjacent interphase epichromatin. It appears that hydrated ~ 30-nm chromatin fibers are quite rare in most cells, possibly confined to interphase epichromatin at the nuclear envelope.The recently introduced, highly sensitive and specific SS18-SSX immunohistochemistry (IHC) is an attractive alternative to SS18 fluorescence in situ hybridization (FISH) testing in synovial sarcoma (SS). However, little is known about how SS18-SSX IHC correlates with SS18 FISH. We correlated the SS18 FISH results of SS from 36 patients with SS18-SSX IHC. Twenty-six tumours had a classic break-apart FISH pattern (1 fused, 1 red and 1 green signal) and all stained positive for the IHC. Ten had an atypical (non-classic) FISH pattern of which 5 stained positive for the IHC. Four of these (including two with novel atypical SS18 FISH patterns) were confirmed to harbour the SS18-SSX fusion on targeted RNA sequencing, while one had classic features of a biphasic SS. The remaining 5 tumours stained negative for the IHC. One had a TPM3-NTRK1 fusion, and one had no fusion, while the remaining three had insufficient tissue/RNA for sequencing. The sensitivity of the IHC was 91% (after excluding the 2 cases with confirmed absence of SS18-SSX fusion).
