National Trends and Outcomes in Dialysis-Requiring Acute Kidney Injury in Heart Failure: 2002–2013

Background

Dialysis-requiring acute kidney injury (D-AKI) is a serious complication in hospitalized heart failure (HF) patients. However, data on national trends are lacking after 2002.

Botulinum Toxin in the Treatment of Muscle Specific Oro-Facial Pain: A Literature Review

Facial pain associated with temporomandibular joint (TMJ) and surrounding structures has been a challenge to clinicians as far as diagnosis and management is concerned. Complexity of anatomical structures within a small area, function of teeth and surrounding periodontal ligament, action of muscles, pathologies, lack of diagnostic investigations, all these complicate specific diagnosis of TMJ disorders. Various classifications have been designed and studied to help diagnose and treat TMJ related disorders, of which the simplest one is pain from TMJ proper and surrounding muscles. Many treatment modalities to treat pain arising from muscles around TMJ like splints, mouth restriction exercises, injection of sclerosing agents etc. have been used with various degrees of success. Botulinum toxin has been shown to be effective in the treatment of oro-facial pain due to muscular disorders and the same is discussed in detail in this review literature.     

Ophthalmic Complication Following Posterior Superior Alveolar Nerve Block for Tooth Extraction! A Rare Occurrence

One of the most commonly asked question by a patient who comes for extraction especially in the rural areas is whether the procedure will cause problems to the eye!! In reality however, ophthalmic complications following routine maxillary molar extractions are practically unheard of. When they occur they can be extremely unnerving not just to the patient but also to the surgeon. Patients generally panic which makes it tougher for the clinician to assess the situation. We present a case of a 26 year old female patient developing ophthalmic complication following local anesthesia administration during extraction of upper left maxillary third molar. In this article, ophthalmic complications arising from posterior superior alveolar nerve block are discussed and management guidelines are highlighted.     

Neonatal Severe Hyperparathyroidism due to Compound Heterozygous Mutation of Calcium Sensing Receptor (CaSR) Gene Presenting as Encephalopathy

The authors report a 14-d-old neonate who presented with lethargy, polyuria and dehydration and was found to have severe hypercalcemia with hyperparathyroidism. This neonate was treated with saline hydration, diuresis and injection pamidronate. Genetic analysis revealed a compound heterozygous mutation of CaSR.     

Effect of occlusal splint therapy on maximum bite force in individuals with moderate to severe attrition of teeth

ObjectiveThe purpose of the pilot study was to determine the effect of restoring lost occlusal vertical dimension (OVD) due to attrition on maximum bite force in humans.MethodologyA total of 124 subjects in age range of 25–40 years, with moderate to severe attrition, having full complement of teeth were screened according to inclusion and exclusion criteria. After consent, occlusal vertical dimension was assessed by employing mechanical and physiological methods in the experimental group and a maxillary canine guided hard splint was fabricated for each subjects fulfilling inclusion criteria and with positive consent (78). Bite force in experimental group was measured before, immediately after delivery of splint and subsequently at an interval of four, eight, and twelve weeks. Due loss during follow up, only 50 subjects could be available for bite force recording till 12 weeks. Bite force of age, gender, height and weight matched controls with no signs of attrition was also measured for comparison.ResultsBite force of the experimental group was found to be significantly less than the matched controls (P = 0.000) initially. After delivery of splint, bite force values increased progressively till twelve weeks. However comparison of bite force values of experimental group with control group showed no significant difference at end of eight (P = 0.008) and twelve weeks (P = 0.162).ConclusionIt was concluded that maximum bite force increases with restoration of lost vertical using splint therapy. A time period of 8–12 weeks is required to restore the maximum bite force value approximately similar to matched controls.
