Geostatistical approach for management of soil nutrients with special emphasis on different forms of potassium considering their spatial variation in intensive cropping system of West Bengal, India.

A large part of precision agriculture research in the developing countries is devoted towards precision nutrient management aspects. This has led to better economics and efficiency of nutrient use with off-farm advantages of environmental security. The keystone of precision nutrient management is analysis and interpretation of spatial variability of soils by establishing management zones. In this study, spatial variability of major soil nutrient contents was evaluated in the Ghoragacha village of North 24 Parganas district of West Bengal, India. Surface soil samples from 100 locations, covering different cropping systems of the village, was collected from 0 to 15 cm depth using 100×100 m grid system and analyzed in the laboratory to determine organic carbon (OC), available nitrogen (N), phosphorus (P), and potassium (K) contents of the soil as well as its water-soluble K (KWS), exchangeable K (KEX), and non-exchangeable forms of K (KNEX). Geostatistical analyses were performed to determine the spatial variation structure of each nutrient content within the village, followed by the generation of surface maps through kriging. Four commonly used semivariogram models, i.e., spherical, exponential, Gaussian, and linear models were fitted to each soil property, and the best one was used to prepare surface maps through krigging. Spherical model was found the best for available N and P contents, while linear and exponential model was the best for OC and available K, and for KWS and KNEK, Gausian model was the best. Surface maps of nutrient contents showed that N content (129-195 kg ha(-1)) was the most limiting factor throughout the village, while P status was generally very high ( 10-678 kg ha(-1)) in the soils of the present village. Among the different soil K fractions, KWS registered the maximum variability (CV 75%), while the remaining soil K fractions showed moderate to high variation. Interestingly, KNEX content also showed high variability, which essentially indicates reserve native K exploitation under intensive cultivation. These maps highlight the necessity of estimating the other soil K fractions as well for better understanding of soil K supplying capacity and K fertilization strategy rather than the current recommendations, based on the plant-available K alone. In conclusion, the present study revealed that the variability of nutrient distribution was a consequence of complex interactions between the cropping system, nutrient application rates, and the native soil characteristics, and such interactions could be utilized to develop the nutrient management strategies for intensive small-holder system.

Effect of donor parameters and cell separators on yield of apheresis platelet and their impact on corrected count increment in aplastic anemia patients.

BACKGROUND: The new cell separators make it simple to collect single donor platelets (SDP), although the platelet yield may vary depending on the cell separator used and donor-related clinical and laboratory variables. AIMS: This study aims to study the factors affecting SDP yield and corrected count increment (CCI). MATERIALS AND METHODS: This retrospective study was carried out at a tertiary care facility in northern India, over 4 years (May 2017-April 2020), data were retrieved and analyzed. STATISTICAL ANALYSIS: Categorical variables were presented as proportions, while continuous variables were presented as mean with standard deviation, P < 0.05 was considered significant. RESULTS: We found a positive correlation between predonation platelet count and yield (r = 0.243, P = 0.000). No such significant correlation was found with Hb concentration (r = 0.025, P = 0.720), age (r = 0.016, P = 0.820), sex (r = -0.038, P = 0.584), and weight (r = -0.025, P = 0.714). Maximum platelet yield and minimum time were seen with Trima. Only 39.3% (33/84) meet the 24 h CCI. The majority of patients did not meet the desired CCI could be due to the patients' clinical condition. On logistic regression, we found a significant association of 24 h CCI with product yield (odds ratio [OR] = 0.168, P = 0.015) and posttransfusion platelet count (OR = 0.454, P < 0.05). CONCLUSION: The only donor-related factor that influences yield is predonation platelet count, whereas 24 h CCI may depend on the clinical status of the patient and yield.

Hypocoagulability in Children With Decompensated Chronic Liver Disease and Sepsis: Assessment by Thromboelastography.

Objective: To evaluate the coagulation status of children with decompensated chronic liver disease (DCLD) and infection and factors affecting it using thromboelastography (TEG). Methods: Coagulation status of children admitted with DCLD and infection was assessed by international normalized ratio (INR), platelet count, and TEG [reaction time (R), kinetic time (K), α-angle (AA), maximum amplitude (MA), coagulation index (CI), and lysis index (LY30)] at admission and at 7-14 days after treatment. CI < -3 represents hypocoagulable state. Clinical profile including systemic inflammatory response syndrome (SIRS), infection severity, bleeding, treatment response, and outcome were noted. Results: Thirty children (21 boys, median (IQR) age 78 [15.7-180] months) were studied prospectively. At admission, 29 (96.7%) had prolonged INR, 24 (80%) had thrombocytopenia, and 17 (56.6%) were hypocoagulable by TEG. Nine of 30 (30%) had normal TEG but deranged INR and platelets. Nineteen (63.3%) cases had SIRS, 11 (36.6%) had severe sepsis, and 8 (26.6%) had bleeding. Hypocoagulable state was common in severe sepsis than sepsis/infection (81.1% versus 42.1%; P = 0.05) and persistent (n = 4) versus recovered SIRS (n = 15, 100% versus 33%; P = 0.03). Bleeders had prolonged R-time (7.8 versus 5.4 min; P = 0.03), smaller MA (30.2 versus 47 mm; P = 0.05), and α-angle (40.4 versus 62.9; P = 0.03) but similar INR and platelets than nonbleeders. Six patients (20%) had poor in-hospital outcomes; R-time ≥8.5 min predicted mortality with high sensitivity (83%) and specificity (100%). Conclusions: Fifth-seven percent of children with DCLD and infection were hypocoagulable by TEG. Severe sepsis and persistent SIRS worsened the coagulation status. TEG identifies bleeders better than INR and platelet count. R-time ≥8.5 min predicts a poor hospital outcome.

Enhanced clearance of Abeta in brain by sustaining the plasmin proteolysis cascade.

The amyloid hypothesis states that a variety of neurotoxic beta-amyloid (Abeta) species contribute to the pathogenesis of Alzheimer's disease. Accordingly, a key determinant of disease onset and progression is the appropriate balance between Abeta production and clearance. Enzymes responsible for the degradation of Abeta are not well understood, and, thus far, it has not been possible to enhance Abeta catabolism by pharmacological manipulation. We provide evidence that Abeta catabolism is increased after inhibition of plasminogen activator inhibitor-1 (PAI-1) and may constitute a viable therapeutic approach for lowering brain Abeta levels. PAI-1 inhibits the activity of tissue plasminogen activator (tPA), an enzyme that cleaves plasminogen to generate plasmin, a protease that degrades Abeta oligomers and monomers. Because tPA, plasminogen and PAI-1 are expressed in the brain, we tested the hypothesis that inhibitors of PAI-1 will enhance the proteolytic clearance of brain Abeta. Our data demonstrate that PAI-1 inhibitors augment the activity of tPA and plasmin in hippocampus, significantly lower plasma and brain Abeta levels, restore long-term potentiation deficits in hippocampal slices from transgenic Abeta-producing mice, and reverse cognitive deficits in these mice.

Replacing winter rice in non-traditional areas by strawberry reduces arsenic bioaccumulation, and improves water productivity and profitability.

Use of huge amount (1450-1650 mm) of arsenic contaminated (14.0-24.5 mg l-1) ground water to irrigate winter rice resulted in high deposition of arsenic (As) in the topsoil and in rice grains, posing a serious threat to soil and human health of the Bengal basin. Strawberry (Fragaria × ananassa Duch.) requires 250 mm irrigation and fetches 3.5 times more net return over the winter rice, and can be grown as an alternate crop in place of winter rice to save the environment. In comparison to rice As load in edible parts of strawberry reduced from 865 to 39 µg kg-1. Deficit irrigation (0.8 and 0.6 crop evapotranspiration, ETc) to strawberry further reduced total as well as different As species load in fruits. Jute and straw mulches recorded lower As in fruits over other mulches. Drip irrigation to recharge full or 80% of ETc loss and use of jute agrotextile surface mulch maximized root growth and yield in strawberry, benefit:cost ratio, and energy efficiency and productivity. Results demonstrate that strawberry cultivation in non-traditional winter rice growing areas of Bengal basin can potentially benefit millions of people by reducing As load in food chains, ensuring higher returns, and aid in reviving the local jute agrotextile industry.

A study of spectrum of pulmonary pathology and expression of thyroid transcription factor-1 during neonatal period.

CONTEXT: Neonatal period is the single most hazardous period of life. The major causes of neonatal death are prematurity and respiratory distress syndrome. We report a series of neonatal autopsies in our Neonatal Intensive Care Unit with special emphasis on pulmonary pathology. The spectrum of pathological changes in the lungs and thyroid transcription factor-1 (TTF-1) expression was studied in detail with reference to its spatial distribution. AIMS: This study aims to analyze the causes of neonatal death with special attention to pulmonary pathology along with associated histopathological changes in lungs. We also evaluated the expression of TTF-1 at different levels of the airway. MATERIALS AND METHODS: After taking consent and anthropometric measurements, autopsy was performed. Weights of all organs were taken, and histological sections were examined under hematoxylin and eosin stain. TTF-1 immunostaining was done on lung sections. Localization of TTF-1 was evaluated at the intrapulmonary level of terminal bronchioles (TBs), distal bronchioles, and alveoli. RESULTS: We performed a series of 25 autopsies in neonates. In our series, most of the neonates were preterm (64%), had low birth weight (44%), and died within the first 7 days of life (80%). Majority (60%) of the neonates died due to pulmonary causes, followed by septicemia (24%), congenital anomalies (12%), and birth injury (4%). Among the respiratory causes, hyaline membrane disease (HMD) was diagnosed in maximum number of cases (32%), followed by pneumonia (12%) and pulmonary hemorrhage (12%). The TTF-1 expression in TBs, distal airways, and alveoli was significantly reduced or absent in cases of HMD compared to the control group. CONCLUSIONS: In this study, we observed that HMD is the most common cause of perinatal death among respiratory disorders, and in this disease, the expression of TTF-1 is significantly reduced in TBs, distal airways, and alveoli compared to the control group.

A Rare Case of Hemangioendothelioma of Urinary Bladder.

Hemangioendothelioma is a vascular tumor of endothelial nature of intermediate grade. It most commonly arises from soft tissue of upper and lower extremities. We report a rare case of epithelioid hemangioendothelioma of the urinary bladder. Histologically, it was a vascular tumor formed by smaller capillaries lined by plump epithelioid cells having eosinophilic cytoplasm. Diagnosis was confirmed by immunohistochemistry, as the tumor cells were positive for CD34 and smooth muscle actin.

VEGF Expression to Support Targeted Therapy in Ovarian Surface Epithelial Neoplasms.

INTRODUCTION: Vascular Endothelial Growth Factor (VEGF), a promoter of angiogenesis, is a promising target for anti-angiogenic therapy in ovarian cancer. In our study, we examined the expression of VEGF in the spectrum of epithelial ovarian neoplasms (benign, borderline and malignant) by Immunohistochemistry (IHC). AIM: Diagnosing ovarian epithelial neoplasms, examining the expression of VEGF in benign, borderline and malignant neoplasms and correlating it with histological grade and stage of malignant cases. MATERIALS AND METHODS: This is a cross-sectional, observational study where, total of 50 cases of surface epithelial ovarian neoplasms were examined for expression of VEGF by IHC. Scoring for VEGF expression was done for each case. RESULTS: A total of 42 of the 50 cases (84%) showed VEGF expression. Out of the 42 positive cases, 19 were high VEGF expressors and 23 were low VEGF expressors. VEGF expression was significantly higher in carcinomas as compared to benign and borderline neoplasms (p=<0.001). All neoplasms of serous morphology were positive for VEGF. High VEGF expression was significantly associated with high grade (p=0.003) and stage (p=0.001) of disease. CONCLUSION: Ovarian surface epithelial neoplasms significantly express VEGF. Though, some VEGF expression was noted in benign and some borderline neoplasms, high VEGF expression was noted only in carcinomas and one case of borderline serous papillary tumour. Thus, these results suggest that epithelial ovarian tumours are candidates for VEGF targeting therapy as most of them are dependent on VEGF for progression.

FNAC aided diagnosis of clear cell sarcoma of kidney: Report of two cases in infants.

Clear cell sarcoma of kidney (CCSK) is a rare aggressive malignant renal neoplasm with a high metastatic potential. Its outcome has however, improved with the advent of doxorubicin based neoadjuvant chemotherapy. Here, we present two cases of CCSK in infants diagnosed on cytology followed by nephrectomy. The first case presented in the neonatal period and had the unusual histological finding of islands of cartilage. The second case presented at the age of eight months. The possibility of CCSK should, therefore, be considered in the differential diagnoses of renal masses in infants as well as neonates. Diagn.

Fibrosarcomatous change in the background of dermatofibrosarcoma protuberans in male breast: Study of a rare case and review of the entity.

Dermatofibrosarcoma protuberans is a cutaneous soft tissue neoplasm with potential for local recurrence but distant metastasis is rare. Trunk and extremities are most commonly involved. This case presented as left-sided breast lump in a male patient. The patient underwent left-sided modified radical mastectomy. Tissues were subjected to histopathological and immunohistochemical test subsequently. The tumor cells showed storiform arrangement with nuclear pleomorphism and increased mitotic figures at places. They were reactive to CD34 and non-reactive to S-100, smooth muscle actin, desmin, cytokeratin and epithelial membrane antigen. The diagnosis of dermatofibrosarcoma protuberans with areas of fibrosarcomatous change was given. Though trunk is a common site for this tumor but its presentation as male breast lump has made the case unique.

De novo myeloid sarcoma involving mandible in a child: Report of a rare occurrence.

Myeloid sarcoma (MS) is a rare malignant disease defined as extramedullary infiltration of immature myeloid cells. We reporte a 2-year-old male of isolated MS who presented with swelling over the left side of the body of the mandible. Proper histological examination and adequate panels of immunohistochemical stain led to the accurate diagnosis. Early intervention with systemic chemotherapy regimens based on cytarabine is the treatment of choice. The role of chromosomal aberrations and genetic abnormality related to prognosis remain uncertain.

Primary central nervous system teratoma with sarcomatous transformation in a young girl: Report of a rare case.

A 13-year-old girl presented with chief complaints of severe headache and vomiting followed by hemiparesis. Radiological examination suggested a space occupying lesion in the right parietal lobe. Craniotomy and debulking of the tumor mass were done. Histopathological and subsequent immunohistochemical examination showed a tumor composed of fascicle of atypical spindle cells which revealed reactivity to vimentin with interspersed areas of well-differentiated cartilage tissue. Hence, the diagnosis of teratoma with sarcomatous transformation was given. Detailed discussion including review of literature has been made regarding different aspect of the tumor.

Primary Merkel cell carcinoma of the oral mucosa in a young adult male: report of a rare case.

Merkel cell carcinoma (MCC) is a highly aggressive neoplasm of skin with neuroendocrine differentiation. Primary MCC of the oral mucosa is exceedingly rare and even more unresponsive to therapy. A 15-year-old male presents with gradually increasing painless swelling in right side of the floor of mouth for 6 weeks. Computed tomography of head and neck region showed globular mass (4.6 cm × 1.7 cm) involving right side of the floor of mouth. Fine-needle aspiration from the upper deep cervical node suggested small round cell tumor. A trucut biopsy showed mass composed of trabeculae and nests of tumor cells with high N:C ratio, granular speckled chromatin, scanty to moderate amount of clear vacuolated cytoplasm. Cells were immunoreactive for cytokeratin-20, CD56, c-kit, CD99 and negative for p63, thyroid-transcription factor-1, CDX2, synaptophysin, neuron-specific enolase. Patient was started on chemotherapy with cyclophosphamide, doxorubicin and vincristine. The mass regressed in size and patient underwent wide local excision with pull-through approach. Patient is currently under combined chemoradiation regime and doing well.

A Rare Case of Cytokeratin-Positive Interstitial Reticulum Cell Sarcoma and Review of the Entity.

The tumors of dendritic/reticulum cells constitutes the rarest tumors affecting the lymphoid tissues. Among them tumors derived from fibroblastic reticular cells (FBRCs) are very rare, and those of cytokeratin (CK)-positive interstitial reticulum cells (CIRCs) origin are even more rare. These tumors can be easily misdiagnosed as tumors of other dendritic cells, myofibroblastic tumors or even metastatic poorly differentiated carcinomas. Less than twenty such cases have been reported in the literature till date. We present such a rare case of CIRC sarcoma in cervical lymph node of a 64-year-old man.

Comparative study of cytology and immunocytochemistry with trucut biopsy and immunohistochemistry in diagnosis of localized lung lesions: A prospective study.

BACKGROUND: Percutaneous lung biopsy is now a common procedure in pulmonary medicine, and several different techniques are in use. The most common has been the use of a fine needle under computed tomography (CT) guidance combined with the trucut needle for histology. AIM: To evaluate the efficacy of fine needle aspiration cytology (FNAC) and immunocytochemistry in comparison with trucut biopsy and immunohistochemistry in patients with localized intrathoracic lesions suspicious for malignancy. MATERIALS AND METHODS: Eighty patients with localized mass lesions in the lung on imaging (chest radiograph/CT) were selected for this study over a period of 1 year. FNAC was carried out by a 22 G spinal needle after localization of the mass in the CT scan followed by guided trucut biopsy. Immunocytochemistry and immunohistochemistry were performed as and when required. RESULTS: The mean age of our study population was 57.6 years and the M:F ratio was 4.2:1. Majority of the lesions were peripheral and in the right lung. Adenocarcinoma was most prevalent (49%), followed by squamous cell carcinoma and small cell carcinoma. Cyto-histopathological concordance was seen in 60 cases (75%). The highest rate of concordance was seen in small cell carcinoma (83.3%). The overall sensitivity of FNAC in distinguishing malignant lung lesions from benign lesions was 84.2% and the specificity was 100%. The sensitivity of cytology in diagnosing small cell carcinoma was 83.3% and of non-small cell carcinoma was 65.38%. Immunocytochemistry was carried out in 34 cases, all of which were followed by immunohistochemistry. Cyto-histopathological concordance was noted in 31 of these cases (91.2%). We used the standard panel of four markers (cytokeratin-7, thyroid transcription factor-1, p63 and CD56) for all selected cases. CONCLUSION: Cytology along with immunocytochemistry is highly effective in diagnosing and categorizing lung neoplasms, producing comparable results to trucut biopsy and immunohistochemistry.

Notch signaling in primary endothelial cells.

The Notch family of cell-surface receptors has been proposed to regulate cell-fate decisions by modulating the ability of each cell to respond to environmental cues. In vertebrates, gain-of-function and loss-of-function studies have demonstrated a requirement for Notch signaling for proper patterning of the vasculature during embryogenesis. To examine the molecular mechanisms by which Notch regulates vascular development, we analyzed changes in gene expression in response to Notch signaling. Notch signal transduction and function were assessed in primary human endothelial cells isolated from the dermal microvasculature of neonates, HMVECd. We demonstrate that HMVECd cells express a heterodimeric form of endogenous Notch4 on their cell surface. Using an in vitro coculture assay, we found that Delta4 can function as a ligand for Notch4 in HMVECd cells. Moreover, ectopic expression of an activated allele of Notch4 upregulated the expression of Delta4, suggesting that there may be a regulatory loop between Notch4 and its ligand, Delta4. Notch4 activation also induced the expression of the transcriptional repressors, HES1, HERP1, and HERP2, as well as ephrinB2, an angiogenic factor proposed to be involved in arterial/venous endothelial cell specification.

Sclerosing peritonitis with unilateral ovarian luteinized thecoma in a post-menopausal woman: A case report.

A unique case of unilateral ovarian luteinized thecoma with sclerosing peritonitis is reported because the association between these two conditions is extremely rare. Etiology is not clearly known. A 50-year-old post-menopausal woman presented with pain abdomen and huge swelling. Pelvic contrast-enhanced computed tomography (CECT) revealed a heterogenous enhancing mass arising possibly from ovary and adherent to uterus, bowl loops, and omentum. A spindle cell neoplasm without definite features of malignancy was reported in computed tomography (CT)-guided fine-needle aspiration cytology (FNAC). Ascitic fluid was negative for malignancy. Her serum carcinoembryonic antigen (CEA) (1.1ng/ml) and CA125 (27.6µ/ml) level was within normal limits. Total abdominal hysterectomy with bilateral supracolic omentectomy, resection of part of colon, and supracolic omentectomy was done. Histopathological diagnosis was luteinized thecoma with sclerosing peritonitis. Tumor cells were immunoreactive to smooth muscle antigen (SMA) and CD 99 and non- reactive to ER, PR, Calretinine, and Cytokeratin. Patient developed post-operative sepsis and enterocutaneous fistula, which was managed conservatively and was kept in follow-up. According to current concept, in spite of its large size, wide-spread involvement, mitotic activity, and complications due to peritoneal involvement, behavior of this rare clinical entity is benign.

Activation of coagulation and fibrinolysis during coronary artery bypass grafting: a comparison between on-pump and off-pump techniques.

Coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB) is associated with intense activation of hemostatic mechanisms. But the precise knowledge of the effects of eliminating CPB in patients undergoing off-pump coronary artery bypass grafting (CABG) are not well established. The present study was carried out to compare and document the changes in selected coagulation and fibrinolysis variables in patients undergoing on-pump and off-pump CABG (OPCAB). A total of 42 patients of on-pump and 31 patients of off-pump CABG were selected for the study. Platelet count, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), Fibrinogen and D-dimer levels were measured immediately, 24 h and 7 days after operation and compared with the baseline preoperative values. Statistical analysis was done by mixed ANOVA for repeated measures and Post-hoc tests using the Bonferroni correction, Chi square and unpaired t test. All the parameters were significantly changed (P < 0.05) with the time. Platelet counts, fibrinogen and D-dimer levels were significantly different between on-pump and off-pump CABG patients on immediate and 24 h postoperative period and attained almost same level after 7 days of operation. Fibrinogen level and platelet counts were increased after a sharp fall in the immediate post-operative period whereas D-dimer levels were persistently increased with a sharp peak of rise in the immediate post-operative period in on-pump group. On-pump surgery was associated with excessive fibrinolytic activity immediately after operation. The off-pump group demonstrated less activation of coagulation and fibrinolysis and delayed postoperative response that became almost equal to the on-pump group in the later postoperative period.

Impact of iron deficiency anemia on cell-mediated and humoral immunity in children: A case control study.

OBJECTIVE: The precise role of iron in immune regulation especially in children vulnerable to iron deficiency is not fully known. Hence, this study was conducted to evaluate the effects of iron deficiency anemia (IDA) and its treatment with oral iron supplementation on cell-mediated immunity (CMI) and humoral immunity (HMI) in children. MATERIALS AND METHODS: A total of 40 children (<15 years) with IDA and 40 age-matched healthy children after satisfying the inclusion criteria were enrolled for this case-control study. Flow cytometric evaluation of absolute and relative numbers of cluster of differentiation 4 (CD4) and CD8 (cluster of differentiation 8) lymphocyte subgroups was carried out to assess the CMI and serum Immunoglobulin G (IgG), Immunoglobulin A (IgA), Immunoglobulin M (IgM) were measured to assess the HMI at baseline and 3 months post oral iron supplementation. RESULTS: Significantly lower levels (P < 0.05) of CD4+ T-cells and decreased CD4:CD8 ratios were observed in the iron deficient children. Iron supplementation significantly improved the CD4+ cell counts and CD4:CD8 ratios. However, immunoglobulin levels weren't different between the two groups. CONCLUSIONS: Although IDA did not influence HMI, it significantly impaired CMI, which was improved following iron supplementation for 3 months.

Comparative evaluation of six cytological grading systems in breast carcinoma.

BACKGROUND: Cytological grading is a useful tool for selection of therapy and prognosis in breast carcinoma. Despite having many cytological grading systems, there is still no agreement among pathologists to accept one of them as a gold standard. AIM: This study was undertaken to evaluate six such three-tier cytological grading systems to determine which system corresponds best to histological grading done by Nottingham modification of Scarff Bloom Richardson (SBR)'s method. MATERIALS AND METHODS: In a double-blind study, preoperative cytological grades obtained by six systems on fine-needle aspiration cytology (FNAC) smears were compared by testing concordance, association and correlation with histological grade derived postoperatively by the SBR's method in 57 patients of breast carcinoma. Bivariate correlation studies and multiple linear regressions were done to assess the significance of the different cytological parameters to predict final cytological grades. RESULTS: Robinson's system demonstrated the best correlation (ρ = 0.799; P = 0.000 and τ = 0.765; P = 0.000), maximum percent agreement (77.19%) and a substantial kappa value of agreement (κ = 0.62) with the SBR's grading system. All the six cytological grading systems correlated with histological grading strongly and positively. In multiple regression analysis, all of the cytological parameters of Robinson's system except cell size and nucleoli had significance in predicting the final cytological grade. CONCLUSIONS: Robinson's grading system is simple, more objective and reproducible, and demonstrated the best concordance with histological grading. So, Robinson's system should be used routinely for breast carcinoma aspirates.
