A dissolution method with robust high performance liquid chromatographic (HPLC) analysis for im-mediate release tablet formulation was developed and validated to meet the requirement as per Inter-national Conference on Harmonization (ICH) and United States Food and Drug Administration (USFDA) guidelines. The method involved the use of Agilent ZORBAX Eclipse XDB C18 column, and temperature was maintained at 30 °C. After optimization, the mobile phase was selected as phosphate buffer (KH2PO4, 30 mM):ACN (60:40, v/v) with pH 3.0, and retention time Rt was found as 3.24, 4.16, and 2.55 min for paracetamol (PCM), chlorpheniramine maleate (CPM) and phenylephrine hydrochloride (PH) respec-tively at 265 nm and at a flow rate of 1 mL/min. The relative standard deviation (%RSD) for 6 replicate measurements was found to be less than 2%. Furthermore net analyte signal standard addition method (NASSAM) with spectrophotometer was performed for standard and liquid oral suspension. On the basis of selectivity, sensitivity and accuracy analysis, it was confirmed that this novel method could be useful for simultaneous estimation of the given drug combinations. Two-way analysis of variance (ANOVA) was applied for evaluating the statistical difference between the assay results obtained via both NASSAM and RP-HPLC methods and ultimately no significant difference was found between both the methods. All the methods and results were acceptable and confirmed that the method was suitable for intended use.

Sclerosing stromal tumor is a rare ovarian tumor, occurring in young adults in the second and third decade of life. We report clinical and histopathological features of three cases of sclerosing stromal tumor of the ovary with a review of literature. The tumor has distinct histological features and is easily recognizable when a high index of suspicion is maintained in young patients presenting with an ovarian mass. These tumors are benign and can be treated successfully by enucleation or unilateral ovariotomy.

Biliary obstructions are rarely caused by a foreign body and have received sparse attention. We present an unusual case with pruritis and abdominal pain caused by impacted full length surgical gauze within the common bile duct. The patient had previously undergone an open cholecystectomy. Radiological investigations were inconclusive and suggestive of either a calculus or a cholangiocarcinoma. Surgical exploration revealed full length surgical gauze within the common bile duct. Because imaging modalities are often non-determinant, the possibility of biliary tract obstruction from a foreign body should be borne in mind for patients with unusual presentations, especially those who have previously undergone surgery.

STUDY DESIGN: Prospective study with simple randomization. PURPOSE: To evaluate the results of anterior spinal instrumentation, debridement and decompression of cord and compare it with results of a similar procedure done without the use of anterior instrumentation. OVERVIEW OF LITERATURE: Use of anterior spinal instrumentation in treatment of tubercular spondylitis is still an infrequently followed modality of treatment and data regarding its usefulness are still emerging. METHODS: Thirty-two patients of tubercular paraplegia with involvement of dorsal and dorso-lumbar vertebrae were operated with anterior spinal cord decompression, autofibular strut grafting with anterior instrumentation in 18 patients and no implant in 14 patients. Results were compared on the basis of improvement in Frankel grade, correction of local kyphosis, decrease in canal compromise and further progression of kyphosis. RESULTS: The mean local kyphosis correction in the immediate postoperative period was 24.1degrees in the instrumented group and was 6.1degrees in the non instrumented group. The mean late loss of correction of local kyphosis at 3 years follow-up was 1.7degrees in the instrumented and 6.7degrees in the non instrumented group. The mean improvement in canal compression was 39.5% in the instrumented group and 34.8% in the non instrumented group. CONCLUSIONS: In treatment of tubercular spondylitis by anterior debridement and decompression of the spinal cord and autofibular strut grafting, the use of instrumentation has no relation with the improvement in neurological status, however the correction of local kyphosis and prevention of further progression of local kyphosis was better with the use anterior spinal instrumentation.

We present a case of 50 year old male patient with coexistence of Pneumothorax and Chilaiditi sign. Chilaiditi sign is an incidental radiographic finding of a usually asymptomatic condition in which a part of intestine is located between the liver and diaphragm; however, the term "Chilaiditi syndrome" is used for symptomatic hepatodiaphragmatic interposition. The patient had no symptoms of abdominal pain, constipation, diarrhea, or emesis. Incidentally, Chilaiditi sign was diagnosed on chest radiography. Pneumothorax is defined as air in the pleural space. Pneumothoraces are classified as spontaneous or traumatic. Spontaneous pneumothorax is labelled as primary when no underlying lung disease is present, or secondary, when it is associated with pre-existing lung disease. Our case is the rare in the literature indicating the coexistence of Chilaiditi sign and pneumothorax.
