A Prospective Study of Anterior Segment Ocular Parameters in Anisometropia

PURPOSE: The aim of this study was to investigate the differences in anterior segment ocular parameters in anisometropia >1 D. METHODS: This study included 202 eyes of 101 subjects ranging from 10 to 40 years of age with anisometropia of 1 D or more. The subjects were divided into groups according to anisomyopia, anisoastigmatism, and anisohypermetropia. After providing informed consent, each patient underwent a detailed ophthalmological examination including cycloplegic refraction, best-corrected visual acuity, cover test, axial length (AL) measurement using A-scan ultrasound biometer, keratometry, anterior chamber depth, and central corneal thickness measurement. For each participant, the eye with greater refractive error was compared to the fellow eye via paired t-tests. Correlations between parameters were studied using the Pearson correlation coefficient. RESULTS: The average age of subjects was 21.7 ± 9.3 years. Of 101 subjects, 31 had anisomyopia; 42 had anisohypermetropia; and 28 had anisoastigmatism. A predisposition toward greater myopia in right eyes was noted in anisomyopia (24 of 31 subjects, 77%). The inter-ocular acuity difference was significant in all three groups (p < 0.01). As the degree of anisometropia increased, there was significant positive correlation in the difference in AL in myopes (r = 0.863, p < 0.01) and hypermetropes (r = 0.669, p < 0.01) and the difference in corneal curvature in anisoastigmatism (r = 0.564, p = 0.002) and hypermetropes (r = 0.376, p = 0.014). A significant positive correlation was also present between the anterior chamber depth difference and refractive difference in hypermetropes (r = 0.359, p = 0.020). CONCLUSIONS: This study showed that anisomyopia is correlated only with anterior chamber differences. Anisohypermetropia is correlated with AL differences as well as corneal curvature difference and anterior chamber depth difference. The amount of anisoastigmatism correlates only with corneal curvature difference.

Management Of Rare Lateral Periodontal Cyst

Lateral periodontal cyst (LPC) is an uncommon type of odontogenic cyst of developmental origin that typically occurs laterally on the root surface of a tooth. They are frequently located in the mandibular premolar area followed by the anterior region of the maxilla. It is usually asymptomatic and is discovered on a routine radiograph. The involved teeth are usually vital. Although the occurrence of lateral periodontal cyst is rare, the precision of its diagnosis is necessary so that the correct treatment can be established. The features of a LPC can be easily confused with a odontogenic keratocyst and radicular cyst

Maxillary Labial Frenectomy Using 810nm Diode Laser- A Case Report

Frenectomy is one of the common oral surgical procedures performed in Pediatric dentistry. This case report presents the management of a maxillary high labial frenum attachment in a child patient using 810nm Diode laser.

Management Of Impacted Central Incisor Associated With Two Supernumerary Teeth –a Case Report

Multiple supernumerary teeth without any associated syndromes are not common. A mesiodens is a supernumerary tooth located in the palatal midline between the two maxillary central incisors. Mesiodens may give rise to a variety of complications, such as impaction, delayed eruption and ectopic eruption of adjacent teeth.

Central venous catheter malposition due to dialysis catheter: a case report / 대한마취과학회지

A 56-year-old man on maintenance hemodialysis was admitted to the intensive care unit with septic shock and coagulopathy. As there was a dialysis catheter in the right internal jugular vein, the left internal jugular vein was cannulated with a central venous catheter to initiate vasopressor therapy. A chest X-ray showed formation of a catheter loop inside the left brachiocephalic vein, probably due to hindrance by the dialysis catheter. This report describes the hurdles encountered, repeated cannulation attempts, and serial chest X-ray findings required to obtain acceptable placement of the catheter tip.

MRI detected prevalence of abnormalities in patients of knee pain.

Background: In patients of knee pain diagnosis has utmost important for treatment and to avoid unnecessary surgery. MRI is a non-invasive procedure in evaluation of knee joint. So this study was planned find out the prevalence of abnormalities detected by MRI in patients of knee pain. Methods: Fifty patient of knee pain were examined after taking permission from institutional ethics committee by using Siemens Avanto MR machine with a superconducting magnet and field strength of 1.5 tesla using dedicated knee coil (Flex), which were referred from department of Orthopedics & Rheumatology. Results: In this present study 72% patients were males and 28% patients females and their ages ranging from (11-80) years. Knee pain was found common in age group 31-40 years. Menisci lesions (44%) were more common as compared to ligament lesions (14%) in patients of knee pain. Osteoarthritis was found in 40 % of patients of knee pain. Joint effusion and marrow edema was found with incidence of 74% and 62% respectively. 4% patients were suffering from intraarticular tumors. Conclusions: Knee pain can occur at any stage of life due to various causative factors. MRI can demonstrate the exact nature and extent of bony as well as soft tissue abnormality. This has increase the use of MRI in evaluation of patients of knee pain.

Randomized double blinded controlled study of ropivacaine versus bupivacaine in combined spinal epidural anesthesia

Ropivacaine and bupivacaine were compared in various combinations for orthopedic and obstetrics patients. We have compared the clinical efficacy of two combined spinal epidural drug regimens using equal volume of 0.75% isobaric ropivacaine to 0.5% hyperbaric bupivacaine intrathecally, and 0.125% of the plain drug along with epidural opioid for elective lower abdominal surgeries. 50 patients of ASA I or II of either sex, between 18 to 60 years of age scheduled for elective surgery under combined spinal and epidural anesthesia [CSEA] were randomly allocated into two groups. Bupivacaine group [B] received 3 ml of 0.5% bupivacaine intrathecally and 0.125% bupivacaine with fentanyl 2 microg/ml epidurally while Ropivacaine group [R], received 3 ml of 0.75% ropivacaine intrathecally and 0.125% ropivacaine with fentanyl 2 microg/ml epidurally. The two groups were compared for the onset of analgesia, onset of motor blockade, duration of analgesia, time for motor recovery and the haemodynamic variables. There were no significant haemodynamic changes in both the groups. The onset of motor block was similar in both groups [4 min] but the onset of sensory block was faster with group B patients [4 min] as compared to group R [6 min]. The duration of analgesia and the time till the need for start of epidural infusion was longer in group B [221.60 +/- 10.677 min] when compared to group R [198.40 +/- 23.216 min]. However, the time for regression of motor blockade was faster in group R [172.20 +/- 10.712 min] as compared to group B [205.20 +/- 13.423 min], facilitating early ambulation of the patients. This study illustrates that both the regimens were comparable in terms of level of block, analgesia and haemodynamic stability. Intrathecal ropivacaine and epidural ropivacaine with fentanyl was shown to result in adequate level of block, complete analgesia and haemodynamic stability. The onset of analgesia however was faster in patients who received intrathecal bupivacaine

Anesthetic management of a case of alkaptonuria

Alkaptonuria is a rare inherited autosomal recessive disorder of metabolism due to deficiency of homogentisic acid oxidase. This results in deposition of homogentisic acid in almost all the collagenous structures of the body leading to progressive multisystem involvement [alkaptonuric ochronosis] and poses a big challenge in anesthetizing such patients. We present one such case posted for total hip replacement and its successful management under general anesthesia
