Lymphangiectasia of small intestine presenting as intussusception
Katoch Pervez,Bhardwaj Subhash
Indian Journal of Pathology and Microbiology , 2008,
Abstract: Intussusception is defined as telescoping of a segment of gastrointestinal tract into an adjacent one. In small children, it is the commonest cause of intestinal obstruction. More than 90% of childhood intussusceptions are idiopathic. We report a rare case of localized small intestinal lymphangiectasia, presenting as intussusception in a 6-month-old male child. The child presented with features of acute intestinal obstruction for which he was later operated. The gross examination of excised ileocecal mass revealed intussusception. Histopathologic examination revealed lymphangiectasia of small intestine, which acted as a lead point for ileocecal intussusception. Postoperative period was uneventful.
Primary Laryngeal Histoplasmosis
Pervez Katoch, Subash Bhardwaj
JK Science : Journal of Medical Education & Research , 2009,
Abstract: Histoplasmosis presenting primarily as laryngeal infection is relatively uncommon and can be mistaken forpapillomatosis or even carcinoma of the larynx.We report a case of localized form of histoplasmosis whichis extremely rare. It was apparently a primary infection of the larynx with no other systemic involvement.A 20 year old male presented with history of difficulty and pain during swallowing. Indirect laryngoscopyrevealed a growth in cricoid region. Histopathological examination of the biopsy material revealedhistoplasmosis which was confirmed by using special stains for fungi (Gomori's methanamine and PAS).
Cytological grading of breast cancers and comparative evaluation of two grading systems

Journal of Cytology , 2010,
Abstract: Aim: To evaluate and compare the cytograding of breast cancers using Robinson′s and Mouriquand′s grading methods. Materials and Methods: A 5-year retrospective (from Oct 2000 to Sept 2005) and 1-year prospective study (from Oct 2005 to Oct 2006). A total of 110 fine-needle aspiration cytology (FNAC) cases of breast cancers were studied. These were graded according to Robinson′s and Mouriquand′s grading methods (grade I-III) followed by comparison of the two methods. Results: Of the 110 cases graded according to Robinson′s method, 28 (25.45%) cases were grade I, 46 (41.81%) grade II, and 36 (32.72%) were grade III, whereas using Mouriquand′s grading methods, 28 (25.45%), 42 (38.18%), and 40 (36.36%) cases were graded as grade I, II, and III, respectively. A high degree of concordance was observed between the two grading methods (90.9%). A highly significant relationship between the scores obtained by two methods was also observed (P=0.004). Conclusions: A comprehensive cytological grading of breast cancers is possible by using two different methods proposed by Robinson and Mouriquand. In spite of a high degree of concordance between the two methods, the Robinson′s grading system has been found to be easier and better because of more objective set of criteria and easy reproducibility.

Spectrophotometric Determination of Kelthane in Environmental Samples  [PDF]
Etesh K. Janghel, Y. Pervez
American Journal of Analytical Chemistry (AJAC) , 2011, DOI: 10.4236/ajac.2011.26083
Abstract: Sensitive spectrophotometric method for determination of kelthane in sub parts per million level is described, which is based on Fujiwara reaction. Kelthane on alkaline hydrolysis gives chloroform, which can be reacted with pyridine to produce red colour. The colour is discharged by addition of glacial acetic acid. Then Benzidine (4,4’-Bianiline) reagent is added due to which a yellowish-red colour is formed which has an absorption maximum at 490nm. Beer’s law is obeyed in the range of 3.3 - 26.0 µg (0.13 - 1.04 ppm) of Kelthane per 25ml of final solution. The molar absorptivity and Sandell’s sensitivity were found to be 4.32 × 105 L?mol–1?cm–1 and 0.022 µg?cm–2 respectively. The method is found to be free from interferences of other organochlorine pesticides and various co-pollutants and can be successfully applied for the determination of kelthane in environmental samples.
