Endoilluminator-assisted pediatric cataract surgery with hazy cornea

The purpose of this study was to demonstrate the usefulness of endoilluminator in pediatric cataract with hazy corneas. We describe a series of three cases of pediatric cataract where visualization of intraocular structures was inadequate under the operating microscope. The endoilluminator was held at the limbus with light directed obliquely to visualize the details of intraocular structures against the hazy cornea using oblique illumination. It allowed structures behind the hazy cornea to be seen with ease. A simple modification in surgical procedure of pediatric cataract using an endoilluminator helps in better visualization of intraocular structures in difficult situations.

Determination of time elapsed since death from the status of transparency of cornea in Ranchi in different weathers.

Determination of ‘time elapsed since death’ (TSD) is one of the important content of the post-mortem report. Although the status of transparency of cornea is variable, depending on different factors like other parameters used for the purpose of determination of time since death but it is less variable as compared to others. The study sample comprised of 238 medico-legal autopsies conducted in the department of Forensic Medicine & Toxicology, Rajendra Institute of Medical Sciences, Ranchi, Jharkhand during June 2006 to September 2007. In majority of cases cornea remains transparent & moist in 0—06 Hrs and becomes transparent & dry in 06—12 Hrs, transparent to hazy in 12—24 Hrs, hazy to opaque in 24—36 hrs and opaque in >36 Hrs. In sequence, changes occurs more in warm & moist weather then in warm & dry weather and cold & moist weather respectively and least in cold and dry weather.

Intravascular ultrasound assessment of the causes of coronary angiographic hazy lesions / 中国综合临床

Objective To identify the causes of coronary angiographic hazy lesions by intravascular ultrasound (IVUS) to avoid inappropriate stenting. Methods Twenty-five cases with hazy regions on coronary angiogram were consecutively identified from July 2009 to March 2010. Hazy regions were defined by coronary arteriongraphy as reduced contrast density without a clearly defined intimal tear, dissection,thrombus,or stenosis ( ＞ 50% ). This cohort of patients were subsequently underwent IVUS examinations and treated according to the results of IVUS. Results The lumen CSAs were settled as ＞ 4. 0 mm2 in all examinations. Among all 25 cases,hazy lesions were located in left anterior descending in 12 patients, right coronary artery in 6 patients, left circumflex in 5 patients, and left main artery in 2 patients. According to the IVUS findings, 2 cases showed absolutely normal or near-normal arterial wall structure image, 10 cases showed calcified plaque,5 cases showed plaque rupture,3 cases showed eccentric plaque ,2 cases showed thrombosis formation,2cases showed dissection,1 case showed subintimal hematoma. Seven patients received stent implantation, and the rest accepted medical therapy. There were no in-hospital MACEs reported among all patients. Conclusion Nearly half of the coronary arteriongraphic hazy lesions were caused by calcified plaque. IVUS can distinguish calcified plaques from intimal tears, thrombus and other underlying etiologies,and help to avoid unnecessary stenting.
