When the serum iron profile of individuals was analyzed, majority (54.25%) of the patients were found to have acute phase reaction and most of them were in advanced stage of renal failure. Normal serum iron profile was found in 37.2% patients, iron overload in 2.2%, anemia of chronic disease in 5.3% and iron deficiency in 1% cases. These findings were statistically significant with the P value of 0.001.</p> <p><strong>Conclusion:</strong> Most common type of serum iron profile found in the study population was acute phase reaction (54%) and majority of them were in stage 5 renal failure. Hence, before beginning an iron therapy, all the patients with anemia in chronic kidney disease should be evaluated for body iron status to prevent iron overload.</p> 2020-07-02T10:07:59+00:00 ##submission.copyrightStatement## https://www.pacificejournals.com/journal/index.php/apalm/article/view/2688 Enhancing Cell Block Quality- A Comparative Study Of Formalin And Agar-Based Methods 2020-07-02T10:20:56+00:00 Shruti Mishra msshruti6@gmail.com Kishore Kumar S. drkishore83@gmail.com Dipanwita Nag avepsaiams@gmail.com <p><strong>Background</strong>: There are not many studies conducted in India to compare cell block preparation methods with reagents and materials that are readily available in all laboratories. This study aimed to standardize and compare two simple cell block techniques, which can be done in low resource settings too. In the study, 35 cases of thyroid, lymph node, and breast were collected for both FNA and cell block preparation for six months.</p> <p><strong>Materials and Methods</strong>: There were separate passes given for both methods. A total of seventy cell blocks made using formalin and agar methods of preparation.</p> <p><strong>Results</strong>: We compared both the methods on technical and morphological levels. The formalin method was overall easy to perform and was yielding good morphological results in 98% cases, the only drawback being cell loss during handling and processing. While in the agar method, there was almost no cell loss, but it was more technically difficult and yielded poorer morphological results. A scoring system was made for cellularity: no cells = 0, hypo-cellular = 1+, hypo-cellular with tissue fragments = 2+, cellular = 3+.18 A score of 2+ and 3+ was scored by 31/35 formalin blocks and 28/35 agar blocks.</p> <p><strong>Conclusions</strong>: The sensitivity of both formalin and agar methods are almost comparable. However, the procedure of the formalin method is far more straightforward and user friendly. Moreover, it also provides a better architectural picture than the agar method.</p> 2020-07-02T00:00:00+00:00 ##submission.copyrightStatement## https://www.pacificejournals.com/journal/index.php/apalm/article/view/2711 Cytomorphological Analysis of Neoplastic Lesions of Neck Node with Special Reference to Lymphomas 2020-07-03T10:29:26+00:00 Junu Devi drjdevipath@gmail.com <p><strong>BACKGROUND</strong>: Neoplastic lesions of lymph node in cervical region pose a diagnostic delima and very often cytological diagnosis proves invaluable.

Mast cells are constantly present in the appendices, and appendix remains one of the common surgical specimens received at pathology laboratory. Mast cells could be one of the important cell population responsible for nerve proliferation and hypertrophy in cases with clinically and histopathologically diagnosed appendicitis.</p> <p>&nbsp;<strong>Material and methods: </strong>The study was done on 100 surgically resected specimens of appendix received for routine histopathological evaluation at the Department of Pathology, Government&nbsp; Medical College, Bhavnagar, between June 2018 and May 2019. All appendices surgically resected as a therapeutic measure for clinically suspected appendicitis included. Cases of&nbsp; normal appendix and acute gangrenous appendicitis were excluded from the study. The appendices were assessed for their histological changes and density of mast cell infiltration. The mast cells were counted in 1% toluidine blue stained sections.</p> <p><strong>Results:</strong>&nbsp; Out of 100 cases of surgically resected appendices, chronic appendicitis was found in 65% of cases and occurred frequently during the second and third decades of life. Highest mast cell count was seen in acute eosinophilic appendicitis and chronic appendicitis. No significant difference was observed in the mean mast cell counts among the different layers of the appendices studied.</p> <p>&nbsp;<strong>Conclusion:</strong> Mast cell counts were found to be highest in acute eosinophilic appendicitis and chronic appendicitis. Intermediate mast cell counts were seen in acute appendicitis and acute suppurative appendicitis.

Though follicular cysts are the most common of the non-neoplastic cysts, the % of occurrence of individual non-neoplastic lesions is not known. Also, often there is dilemma in reporting the exact type of nonneoplastic cyst. This study was planned with the objectives of assessing percentage of non neoplastic cystic ovaries, determining the morphological forms and relation of the various cysts with age of patient, and to detect whether multicystic non neoplastic lesions are more frequent in present day.</p> <p><strong>Materials and methods</strong>: A prospective hospital based cross sectional non-neoplastic ovarian cysts study was done between January to June 2019 in a tertiary hospital. All hysterectomy specimens with the accompanying ovary/ovaries and oophorectomy specimen were included. Microscopic features were assessed. Data was tabulated in MS excel sheet. Percentage of occurrences of age, size, morphological type, laterality and complaints were calculated.</p> <p><strong>Result</strong>:50% of 193 ovaries had non neoplastic cystic lesions. Non neoplastic cysts were associated with fibroid in 54%<strong>, </strong>DUB in 17% and adenomyosis in 16% cases. They were seen commonly during reproductive age group(83%). Post-menopausal age showed 16% cases. 86% of the non neoplastic ovarian cystic lesions were unilateral. 20% non neoplastic cystic lesions were of &lt;1cm, 74% were 1-5 cm in size and 5% were larger than 5 cm. Morphologically 40% were follicular lesions, 32% were simple serous cysts, 14% were haemorrhagic cysts, 8% corpus luteal cysts and 2% each theca lutein and epithelial inclusion cysts.</p> <p><strong>Conclusion</strong>: Non neoplastic cystic ovaries comprised 50% of all ovarian lesions, 83% were seen during reproductive age group. Leiomyoma, dysfunctional uterine bleeding and adenomyosis were the common clinical features and 70% of the cysts were 1-5 cm in size. There was no relation between morphological types of the cystic lesions and functional status. Simple serous cyst, cystic follicle, follicular cyst, cystic corpus luteum, corpus luteal cyst, theca luteal cyst, epithelial inclusion cyst and haemorrhagic cyst were found of which follicular cyst was the commonest (40%) Multicystic non neoplastic lesions or polycystic ovaries were not found during the period of study.</p> 2020-07-07T10:33:06+00:00 ##submission.copyrightStatement## https://www.pacificejournals.com/journal/index.php/apalm/article/view/2791 Study of Various Vesiculobullous Lesions Using Tzanck Smear 2020-07-07T10:39:06+00:00 Sanchit Singhal drsanchit.singhal@gmail.com Hemalata M hemalatajreddy@gmail.com <p><strong>Background:</strong> The vesiculobullous reaction pattern is characterized by the presence of vesicles or bullae within the epidermis or at the dermoepidermal junction. Despite some having characteristic presentations, it’s difficult to make a definite diagnosis clinically. Hence, cytological evaluation is required for reliable and early diagnosis. Objectives of the study are to determine the incidence of various vesiculobullous lesions and evaluate cytology as a tool for early diagnosis of vesiculobullous lesions.</p> <p><strong>Methods:</strong> For Tzanck smears fresh vesicle or bulla was selected and incised with scalpel, reflecting the roof of bulla. Base of the blister scraped gently and material spread on a glass slide. These smears were stained with MGG (air dried), Pap and H&amp;E stains (fixed).Skin punch biopsies from the bullae were subjected to routine fixation, processing, sectioning and staining.</p> <p><strong>Results:</strong> A total of 62 Tzanck smears were done for vesiculobullous lesions of skin of which 29 had histopathological correlation. Herpes constituted the most common vesiculobullous disorder (42%) followed by bullous pemphigoid (27.4%) and pemphigus vulgaris (19.3%). Most patients were in the age group 61- 70 years. The M:F ratio of 1:1.38 showing female preponderance. Tzanck smears showed acantholytic cells in pemphigus group, eosinophils in bullous pemphigoid and multinucleate giant cells in viral blisters. Histopathology showed intraepidermal acantholysis in pemphigus vulgaris, subcorneal blister in pemphigus foliaceus and subepidermal in bullous pemphigoid.</p> <p><strong>Conclusion:</strong> Cytohistopathological correlation showed an overall sensitivity of 79%. Tzanck smear showed 96% sensitivity for viral infections. Tzanck smear is a quick, non-invasive method for the early diagnosis of vesiculobullous disorders.</p> 2020-07-07T10:39:06+00:00 ##submission.copyrightStatement## https://www.pacificejournals.com/journal/index.php/apalm/article/view/2840 Utility of Urine Reagent Strips in CSF Analysis as An Aid to Rapid Diagnosis of Meningitis 2020-07-07T10:45:50+00:00 Abhirami Ganesh R abhihp1991@gmail.com Prabhu M H prabhumural@yahoo.com <p><strong>Background:</strong> Bacterial Meningitis is a medical emergency and timely intervention has an implication on the prognosis and outcome.
