 Objective: To determine the diagnostic yield of cell blocks, prepared by the vapour fixation method, using laboratory supplies easily available at any low resource laboratory setup or outpatient department of a basic healthcare unit. Methods: Prospective descriptive study was carried out at Healthways Laboratories Rawalpindi, for 6 months from 1st January 2017 to 30th June 2017. Walk in patients referred to the lab for FNAC were selected by non probability convenient sampling. After preparing FNAC slides from first pass, the patients were briefed about the cell block material and after informed consent second dedicated passes were done to make cell blocks. Results: Out of 47 cases, there were 25 (53.2 %) breast lumps, 8 (17%) superficial collections, 7 (15.1%) lymphadenopathies, 6 (12.8%) thyroid swellings and 1 salivary gland swelling. Technique yielded moderate to high cellularity in 33 (70.2%) cases, 16 from malignant and 1 from benign breast lumps, 5 from thyroid, 3 from reactive and 3 from metastatic lymphnodes, 3 from abscesses, 1 from lipoma and 1 from salivary gland. Low cellularity 14 (29.8%) cases were from 5 benign and 3 malignant breast lumps, 2 hematomas and 1 case each from thyroid, metastatic lymphnode, abscess and lipoma. Good cellularity was achieved in 16 (84.2%) of 19 cases of malignant breast lesions, 3 (15.8%) were hypo cellular of which 1 was non-diagnostic on FNAC smear. Cell block diagnosis was comparable to FNAC in 35 of 47 (74.4%) cases. Non diagnostic cases on cell block were more, 13 versus 3 cases on FNAC. The kappa value of agreement in diagnosis was 0.64. Conclusions: Poor man’s cell block method is simplest and effective method of cell block preparation which must be advocated at basic healthcare units and low tech laboratory. Its diagnostic potential must be further explored.

Background: A breast lump is the most common symptom associated with both benign and malignant breast diseases. Therefore, a distinction of benign from malignant lump is of importance for proper management. Though a definitive diagnosis is possible with imaging for all the lesions, histopathological study is proven essential for confirming the diagnosis. Objective: The objective of this study was to evaluate the role of USG and histopathological findings of different breast lump in diagnosis and their comparison. Methods: A prospective study was conducted over a period of one year from January 2017 to December 2017. A total of 116 patients were included in this study. All breast lumps underwent surgery and the ultrasound findings of these lumps were compared with the histopathological findings. Data were collected from these patients by a preformed questionnaire and finally the data were analyzed. Results: Out of 116 patients only 21 cases were reported as malignant in ultrasound report but histopathology revealed 31 malignant patients. On histopathological examination 10 benign cases turned out to be malignant. Conclusion: The present study was undertaken to evaluate in diagnosing breast mass lesions individually by ultrasound and compared with histopathology for definitive management of a patient.

INTRODUCTION: Bronchoscopy is a safe and effective method for diagnosing lung carcinomas with a variation in the diagnostic yield with different bronchoscopy guided procedures. Cell block technique has shown an addition cases positivity in diagnosing carcinomas as compared to the conventional method. AIM: The present study was aimed to evaluate the diagnostic utility of cell block technique on Bronchoscopy guided needle aspiration/ Brush and also to compare cytological preparation with cell block. MATERIAL AND METHODS: A total of 50 cases were included in the study that was suspected to be having lung carcinoma. These patients went under bronchoscope guided aspirations (TBNA, EBNA, and Brush). Smears were immediately made for conventional cytology study and well as in another aliquot samples were collected to prepare cell blocks following which H&E staining was done. RESULTS: Out of 50 cases, 8 cases came out to be negative on conventional smears and when compared with cell block technique 4 additional cases came out to be positive who were negative on conventional smears. The diagnosis were compared with histopathology biopsies keeping it as a gold standard and results on cell block techniques were conrmed to be true. CONCLUSION: Out of 50 cases, an additional 4 more cases were diagnosed malignant by using the cell blocks technique but there were few drawbacks with cell block technique. In few of the cases on cell block, cellularity was very less, cells morphology was also not very clear and some showed cells entrapped in a clusters. The conclusion made out of this study is that cell block technique is more accurate than the cytological smears and when used in combination diagnostic efcacy will be improved.

Differential diagnosis of pancreatic masses is challenging. The endoscopic ultrasound-guided fine-needle aspiration method with the highest diagnostic yield has not been established. It was realized a prospective, randomized, double-blind study of the endoscopic ultrasound-guided fine-needle aspiration in solid lesions of the pancreas to compare and evaluate diagnostic yield and aspirate quality between wet and pull technique. Forty-one patients were enrolled. The wet technique presented a sensitivity, a specificity, a positive and negative predictive value, and a diagnostic accuracy of 58.3%, 100%, 100%, 25% and 63.4%, respectively. In the capillary technique they were: 75%, 100%, 100%, 35.7% and 78.1%, respectively. Comparing the diagnostic yield between both techniques, there was no statistically significant difference (McNemar’s test p = 0.388). Regarding the cellularity of the specimen, both in cytology and the cell block samples, no significant difference was observed between the techniques (p = 0.84 and 0.61, respectively). With respect to contaminating blood in the specimen, there was no difference in cytology samples (p = 0.89) and no difference in cell block samples (p = 0.08). The suitability of cytology samples for diagnosis was similar in both techniques (wet = 57.5% and capillary = 56.7%, p = 0.94) and there was no difference in cell block samples (wet = 75% and capillary = 66.1%, p = 0.38). In this study we did not observe differences in diagnostic yield or sample quality. Since both techniques are effective, we suggest the simultaneous and alternate use of both methods.

Background: A palpable lump in a woman’s breast could be benign or malignant and it requires prompt evaluation to confirm or exclude cancer. This study aims to establish the correlation between clinical and radiological parameters for provisional diagnosis of breast lumps and the role of histopathology for final diagnosis of these breast lumps.Methods: Total 275 female patients with palpable breast lumps were included in the study, where a detailed history was recorded and clinical examination was done. All patients underwent ultrasonography of the breast along with fine needle aspiration cytology or histopathology, wherever indicated.Results: Benign breast lumps were found more commonly in 18-30 years of age group whereas malignant breast lumps were seen more commonly in the 41-60 years age group and the incidence increased with age. Fixity to skin was present in 5.1% and fixity to chest wall was present in 5.8% respectively, and all of these cases turned out to be malignant.Conclusions: Attributing factors for suspicion of malignant lumps are advanced age, fixity to surrounding structures, presence of ulceration and peau’d orange breast skin appearance. Although for confirmation of malignancy from a suspected breast lump requires either cytology or histopathology of the excised specimen.

Abstract Background: Typhoid fever, caused by Salmonella enterica serotype Typhi, is endemic in the Indian sub-continent including Bangladesh, South-east and Far-east Asia, Africa and South Central America. The disease can occur in all age group with highest incidence among children. Blood culture is regarded as the gold standard for diagnosis and carry 70-75% diagnostic yield in the first week of illness. However, this requires laboratory equipment and technical training that are beyond the means of most primary health care facilities in the developing world. Typhidot is a rapid dot-enzyme immune assay (EIA), which detects IgG and IgM antibodies to a specific 50 kD outer membrane protein (OMP) antigen of Salmonella enterica serotype Typhi. Typhidot becomes positive as early as in the first week of fever. The results can be visually interpreted and is available within one hour. Materials and method: Fifty blood samples, collected aseptically from patients clinically diagnosed of Typhoid fever, were evaluated by blood culture, Widal test and Typhidot. Results: Of the 50 patients, 33 (66%) were positive by blood culture. Widal test was positive in 33(66%) patients which included 26 in blood culture positive patients and 7 in blood culture negative patients. Typhidot was positive in 37 (74%) patients. Thus, in comparison to the gold standard test i:e blood culture, Typhidot and Widal test had sensitivity and specificity of 100% & 76% and 78.78% & 58.82% respectively. Conclusion: Typhidot is found to have high sensitivity and good specificity and could be applied as a good alternate in resource poor nation. Further, it is simple to perform, reliable when compared to Widal test, and rapid, with results being available in one hour when compared to 48 hours for blood culture and 18 hours for Widal test.

The diagnosis of smear-negative pulmonary tuberculosis (PTB) is particularly challenging, and automated liquid culture and molecular line probe assays (LPA) may prove particularly useful. The objective of our study was to evaluate the diagnostic potential of automated liquid culture (ALC) technology and commercial LPA in sputum smear-negative PTB suspects. Spot sputum samples were collected from 145 chest-symptomatic smear-negative patients and subjected to ALC, direct drug susceptibility test (DST) testing and LPA, as per manufacturers’ instructions. A diagnostic yield of 26.2% was observed among sputum smear-negative TB suspects with 47.4% of the culture isolates being either INH- and/or rifampicin-resistant. Complete agreement was observed between the results of ALC assay and LPA except for two isolates which demonstrated sensitivity to INH and rifampicin at direct DST but were rifampicin-resistant in LPA. Two novel mutations were also detected among the multidrug isolates by LPA. In view of the diagnostic challenges associated with the diagnosis of TB in sputum smear-negative patients, our study demonstrates the applicability of ALC and LPA in establishing diagnostic evidence of TB.
