1.Diffuse Intrinsic Pontine Glioma : Clinical Features, Molecular Genetics, and Novel Targeted Therapeutics
Journal of Korean Neurosurgical Society 2018;61(3):343-351
Diffuse intrinsic pontine glioma (DIPG) is a deadly paediatric brain cancer. Transient response to radiation, ineffective chemotherapeutic agents and aggressive biology result in rapid progression of symptoms and a dismal prognosis. Increased availability of tumour tissue has enabled the identification of histone gene aberrations, genetic driver mutations and methylation changes, which have resulted in molecular and phenotypic subgrouping. However, many of the underlying mechanisms of DIPG oncogenesis remain unexplained. It is hoped that more representative in vitro and preclinical models–using both xenografted material and genetically engineered mice–will enable the development of novel chemotherapeutic agents and strategies for targeted drug delivery. This review provides a clinical overview of DIPG, the barriers to progress in developing effective treatment, updates on drug development and preclinical models, and an introduction to new technologies aimed at enhancing drug delivery.

The goal of this paper is to review the advantages and disadvantages of the various treatment options of temporomandibular joint (TMJ) total joint replacement (TJR). TMJ articles published within the last 20 years were reviewed to collect the information on non-invasive and invasive TMD treatment methods. Recent technological advancements helped the evolution of treatment methods and offered significant value to TMD patients and surgeons. Considering the TMD levels, the therapeutic procedures can involve general health examiniations, physical therapy, medication, oral rehabilation or as an end stage clinical invention, temporomandibular joint replacement. In fact when intra-articular TMD is present, the effective treatment method appears to be TJR. However, concern for infection, material hypersensitivity, device longevity and screws loosening issues still exists. Further combined research utilizing the knowledge and expertise of, surgeons, material scientists, and bioengineers is needed for the development of improved TMD therapeutic treatment.

Objective: To report a new species of sandfly, Sergentomyia
(Neophlebotomus) ashwanii sp. nov. (Diptera: Psychodidae) from
Western Ghats, India.
Methods: A systematic sandfly survey was conducted in the
Thrissur and Kollam districts of Kerala, India using mechanical
aspirators, light and sticky traps, both indoor and outdoor habitats,
for a period of one year. Deoxyribonucleic acid barcoding of samples
was performed targeting mitochondrial cytochrome oxidase I (COI)
gene and sequence generated was subjected to phylogenetic analysis.
Results: Sergentomyia (Neophlebotomus) ashwanii, a new sandfly
species is recorded and described in this communication. A single
row of 10-12 pointed teeth in the cibarium with 4-6 small denticles
or fore-teeth are the key characteristics that is distinctive from
other members of the subgenus Neophlebotomus. Mitochondrial
COI barcode followed by phylogenetic analysis of the nucleotide
sequence confirms that specimens of the species belong to the
same taxonomic group while the genetic distance (14.2%) with the
congeners established it to be a different species.
Conclusions: The Western Ghats' being an important biodiversity
hotspot and has dearth of systematic entomological surveys on
sandflies. The current study tried to fill the void and also report a
new sandfly species.

OBJECTIVE:
The purpose of this study was to test the feasibility of integrating acupuncture into the routine care of living liver and kidney donors during the process of donation and recovery.
METHODS:
This is a pilot study on the feasibility of a brief acupuncture intervention for living liver and kidney donors. Participants received acupuncture immediately prior to organ donation surgery, every day as inpatients, while recovering from donation, and at a 2-week follow-up. Prior to surgery, questionnaires were completed on acupuncture outcome expectations and the State-Trait Anxiety Inventory. After participating, those who received acupuncture provided feedback. Following the active intervention, a retrospective chart review was conducted, using donors who did not receive acupuncture as a comparison cohort.
RESULTS:
Forty donor candidates were approached and recruited, 32 consented and ultimately 25 donors participated in the acupuncture intervention (15 of kidney, 10 of liver), 68% female, and 88% Caucasian; only one had prior experience with acupuncture. Participants received an average of 4 sessions while inpatient (range 2-8). Those who expected acupuncture to be more helpful prior to the intervention reported lower inpatient pain scores (P = 0.04). Qualitative feedback from patients was predominantly positive, indicating acupuncture was helpful for relaxation and pain. However, a few patients reported feeling overburdened during postdonation recovery, and that the study was viewed as additional obligation.
CONCLUSION
Preliminary findings suggest it is feasible to integrate acupuncture into inpatient recovery for living organ donation. Tailoring interventions to the specific needs of patients is important to address ongoing concerns. Larger studies are needed to further ascertain benefits of peri-operative acupuncture.
