Aim: To outline various histopathological types of ovarian cysts received in our teaching hospital along with their prevalence and mode of presentation and to assess the proportion of physiologic versus pathological cysts and benign versus malignant ovarian cysts. Duration of study: From Jan 2019 to March 2021. Methods: Histopathology Department of Bakhtawar Amin Medical & Dental College & Hospital, Multan. A retrospective review of 122 ovarian lesions including physiological/functional cysts, pathological non neoplastic cysts as well as benign, borderline and malignant neoplasm. Histopathology reports of all ovarian specimens were reviewed and counted. Details like age, marital status, parity, presenting complaints, procedure opted, laterality, size, gross and microscopic details and final histological diagnosis etc were recorded. H&E stained slides of all cases were reviewed. In difficult suspicious cases, immunohistochemistry was also carried out. Percentage and proportions were calculated for all the variables. Relevant tables and charts were computed. Results: A total of 122 ovarian specimens with some lesion were segregated in histopathology department of Bakhtawar Amin Hospital from 117 patients with 5 patients having bilateral lesions. The mean age was 33.2 years (ranging from 13-71 years). Most ladies presented between 25-45 years of age. Out of these 117 patients, 18 ladies were unmarried. Out of the 99 married, 12 were nulliparous. Sixty four ladies (54.7%) found to have cysts/neoplasm in right sided ovary, forty eight (41%) presented with left sided ovarian involvement and 5 (4.3 %) presented with bilateral ovarian lesions. Conclusion: Non neoplastic ovarian cysts are more frequent as compared to neoplastic masses. Histopathological diagnosis is mandatory for final confirmatory diagnosis.

Background: Inguinal hernia is one of the most common conditions presented for surgical repair in children and laparoscopic approaches are increasingly performed. Previous studies have shown safety and efficacy in the use of supraglottic devices (SGD) as an alternative to tracheal intubation, which fits particularly well with outpatient anesthesia. Methodology: we conduct a retrospective observational study, collecting data from the electronic anesthetic form, from all patients aged 0 to 17 y who underwent ambulatory laparoscopic percutaneous internal ring suturing between February 2015 and August 2019, if I-gelTM was used to airway management. Results: We found 230 patients meeting the inclusion criteria. The mean age was 5.2 y old, mean weight 20.1 kg. All patients were ASA I (n=203) or ASA II (n=27). The mean surgery duration was 38 minutes. We found 4 respiratory adverse events, three bronchospasms, and one laryngospasm, managed in the operating room. Ninety percent of the surgeries were performed without neuromuscular blockade. Conclusion: I-gelTM was a safe, effective, and convenient alternative to airway management to laparoscopic inguinal hernia repair in the ambulatory setting. According to available literature, our practice did not represent an increased risk for the studied respiratory events. SGD obviates the need for neuromuscular blockade.

Abstract Background MRI provides several distinct quantitative parameters that may better differentiate renal cell carcinoma (RCC) subtypes. The purpose of the study is to evaluate the diagnostic accuracy of apparent diffusion coefficient (ADC), chemical shift signal intensity index (SII), and contrast enhancement in differentiation between different subtypes of renal cell carcinoma. Results There were 63 RCC as regard surgical histopathological analysis: 43 clear cell (ccRCC), 12 papillary (pRCC), and 8 chromophobe (cbRCC). The mean ADC ratio for ccRCC (0.75 ± 0.13) was significantly higher than that of pRCC (0.46 ± 0.12, P < 0.001) and cbRCC (0.41 ± 0.15, P < 0.001). The mean ADC value for ccRCC (1.56 ± 0.27 × 10−3 mm2/s) was significantly higher than that of pRCC (0.96 ± 0.25 × 10−3 mm2/s, P < 0.001) and cbRCC (0.89 ± 0.29 × 10−3 mm2/s, P < 0.001). The mean SII of pRCC (1.49 ± 0.04) was significantly higher than that of ccRCC (0.93 ± 0.01, P < 0.001) and cbRCC (1.01 ± 0.16, P < 0.001). The ccRCC absolute corticomedullary enhancement (196.7 ± 81.6) was significantly greater than that of cbRCC (177.8 ± 77.7, P < 0.001) and pRCC (164.3 ± 84.6, P < 0.001). Conclusion Our study demonstrated that multiparametric MRI is able to afford some quantitative features such as ADC ratio, SII, and absolute corticomedullary enhancement which can be used to accurately distinguish different subtypes of renal cell carcinoma.

Abstract Background The aim of this study is to investigate whether quantitative DW metrics can provide additive value to the reliable categorization of lesions within existing PI-RADSv2 guidelines. Fifty-eight patients with clinically suspicious prostate cancer who underwent PR examination, PSA serum levels, sextant TRUS-guided biopsies, and bi-parametric MR imaging were included in the study. Results Sixty-six lesions were detected by histopathological analysis of surgical specimens. The mean ADC values were significantly lower in tumor than non-tumor tissue. The mean ADC value inversely correlated with Gleason score of tumors with a significant p value < 0.001.Conversely, a positive relationship was found between the ADC ratio (ADC of benign prostatic tissue to prostate cancer) and the pathologic Gleason score with a significant elevation of the ADC ratio along with an increase of the pathologic Gleason score (p < 0.001). ROC curves constructed for the tumor ADC and ADC ratio helped to distinguish pathologically aggressive (Gleason score ≥ 7) from non-aggressive (Gleason score ≤ 6) tumors and to correlate it with PIRADSv2 scoring to predict the presence of clinically significant PCA (PIRADSv2 DW ≥ 4). The ability of the tumor ADC and ADC ratio to predict highly aggressive tumors (GS> 7) was high (AUC for ADC and ADC ratio, 0.946 and 0.897; p = 0.014 and 0.039, respectively). The ADC cut-off value for GS ≥ 7 was < 0.7725 and for GS ≤ 6 was > 0.8620 with sensitivity and specificity 97 and 94%. The cutoff ADC ratio for predicting (GS > 7) was 1.42 and for GS ≤ 6 was > 1.320 with sensitivity and specificity 97 and 92%. By applying this ADC ratio cut-off value the sensitivity and specificity of reader 1 for correct categorization of PIRADSv2 DW > 4 increased from 90 and 68% to 95 and 90% and that of reader 2 increased from 94 and 88% to 97 and 92%, respectively. Conclusion Estimation of DW metrics (ADC and ADC ratio between benign prostatic tissue and prostate cancer) allow the non-invasive assessment of biological aggressiveness of prostate cancer and allow reliable application of the PIRADSv2 scoring to determine clinically significant cancer (DW score > 4) which may contribute in planning initial treatment strategies.

ABSTRACT Background: Leucopenia has been reported after induction of thiopentone barbiturate therapy for refractory intracranial hypertension. However, the incidence and characterisitics are not well described. Aims: We performed a retrospective review to describe the incidence and characteristics of leucopenia after induction of thiopentone barbiturate therapy. Setting and Design: Our centre is a national referral centre for neurotrauma and surgery in a tertiary medical institution.Materials and Methods: We performed a retrospective review of all patients who received thiopentone barbiturate therapy for refractory intracranial hypertension during an 18 month period from January 2004 to June 2005 in our neurosurgical intensive care unit. Statistical Analysis Used: Statistical analysis was performed using SPSS version 15.0. All data are reported as mean ± standard deviation or median (interquartile range). The Chi square test was used to analyze categorical data and student t test done for comparison of means. For paired data, the paired t?test was used.-test was used. Results: Thirty eight (80.9%) out of 47 patients developed a decrease in white blood cell (WBC) count after induction of thiopentone barbiturate coma. The mean decrease in WBC from baseline to the nadir was 6.4 × 10 9 /L (P <lt; 0.001) and occurred 57 (3-147) h after induction. The mean nadir WBC was 8.6 < 3.6 × 10 9 /L. Three (6.4%) patients were leucopenic, with a WBC count of 2.8, 3.1, and 3.6 < 10 9 /L. None of them were neutropenic. We did not find an association between decrease in WBC count and clinical diagnosis of infection. We did not find any association between possible risk factors such as admission GCS, maximum ICP prior to induction of barbiturate coma, APACHE II score, total duration and dose of thiopentone given, and decrease in WBC count. Conclusions: Decrease in WBC count is common, while development of leucopenia is rare after thiopentone barbiturate coma. Regular monitoring of WBC counts is recommended.

Background: Ovarian cystic neoplasms are common in gynaecological practice. These may pose diagnostic difficulty to the pathologists. This study was conducted to analyse the clinical and histological profile of ovarian cystic neoplasms.Methods: This is a retrospective study done from January 2016 to April 2017 in a tertiary care hospital in North East India. All the patients, who were clinically and radiologically diagnosed as ovarian cysts, which had histopathological confirmation were included in the study. Data including the age, parity, clinical symptoms, laterality and histopathological findings were analysed.Results: A total of 101 patients operated for ovarian cysts in the study period were analysed. The most common clinical presentation was lower abdominal pain. There were 11 (10.9%) malignant cases, 4 (4%) were intermediate grade and borderline in nature, and 85 (84.1%) cases were benign in nature. There was 1 (1%) case of metastasis to ovary. Mature cystic teratoma was most common (20.8%) histopathological diagnosis. The second most common cyst was serous cystadenoma (19.8%).Conclusion: Ovarian cysts are commonly encountered in gynaecological practice and equally encountered by the pathologists. Most commonly found ovarian cysts were mature cystic teratoma followed by serous cystadenoma.

Background: Osteosarcoma is a malignant neoplasm that occurs most often in long bones, with the head and neck region being rarely affected, accounting for less than 1% of all cancers in this region. Objective: To report a rare case of a large-extension osteosarcoma with emphasis on its clinical and diagnostic aspects. Case presentation: A 43-year-old woman presenting an intraoral exophytic lesion with involvement of other maxillofacial structures, such as nostril, zygoma and orbit. Despite the initial clinical diagnosis of actinomycosis, an incisional biopsy confirmed the histopathological diagnosis of osteosarcoma, showing a wide morphological variety. Conclusion: This case highlights the importance of clinical and histopathological findings for the correct diagnosis of osteosarcoma. Moreover, it shows that, although surgical resection is the primary treatment for this neoplasia, depending on the extent of the tumor and its proximity to vital anatomical structures, the most appropriate conduct is not always feasible.

To diagnose Helicobacter pylori (HP) infection and its related mucosal injuries requires the histopathological analysis of gastric biopsies. The move from glass slides interpretation towards digital pathology implies technical choices to maintain the performances of histopathological diagnosis. The intra-rater agreement in assessing gastritis diagnostic criteria between glass slides, low resolution and high resolution digital slides in the subject of the present study. One hundred gastric biopsies were re-assessed by a single digestive pathologist on glass slides and digitalised slides at low resolution (ie, x20 magnification and single focus without z-stack) and high resolution (ie, x40 magnification with seven focus levels and z-stack) about the criteria of the updated Sydney system and the detection of HP. Inter-analyses agreement were very good (Kappa values>0.81) for every criteria but slightly inferior (ie, Kappa values<0.9) comparing glass slides interpretations with low resolution digital slides-based ones. Indeed, some HP infections were misdiagnosed using x20 magnification histochemical stained digitalised slides (p<0.05). At the opposite, anti-HP immunohistochemistry slides and/or x40 magnification digitalisation permitted to maintain almost perfect concordance in diagnosis (Kappa value>0.9). As mentioned in current guidelines, a high resolution x40 magnification digitalisation must be favoured in order to avoid some misdetection of microorganisms as HP.

Abstract Study question To investigate differences in In Vitro Fertilization (IVF)/Intracytoplasmic Sperm Injection (ICSI) outcomes between endometriosis women who do or don’t have a concomitant autoimmune disease. Summary answer Despite a higher oocyte yield, a trend for reduction in clinical pregnancy rates was observed in the autoimmunity group compared to women without concomitant autoimmunity. What is known already Endometriosis is an inflammatory chronic gynaecological disorder with a known detrimental impact on fertility. Endometriosis pathogenesis is still unclear. It has been postulated a role of both innate and adaptive immune system. The coexistence of endometriosis and autoimmunity is a well-documented occurrence Some recent findings have revealed an increased risk to have concomitant autoimmune disease in women with endometriosis, but no study has so far investigated whether this association could affect IVF/ICSI outcomes. Indeed, autoimmune phenomena, including proinflammatory cytokines and auto-antibody production, may result in diminished quality of oocytes/embryos with lower pregnancy rates among these patients. Study design, size, duration This was a retrospective observational study carried out at the Fertility Unit of IRCSS San Raffaele Hospital (Milan). We reviewed medical patients’ notes of women with a confirmed diagnosis of endometriosis who referred to our Fertility Unit from October 2018 to January 2021. Participants/materials, setting, methods Out of 1441 patients undergoing IVF/ICSI, 98 women had surgical/histopathological diagnosis of endometriosis. 25 of them had a clinical and/or serological diagnosis of autoimmunity. Autoimmunity was assessed by clinical data (blood tests for auto-antibodies or rheumatological records) obtained from the electronic patient files stored in the database of our Fertility Centre. Clinical pregnancy was defined as the presence of at least one intrauterine gestational sac with a viable embryo at week 6 after transfer. Main results and the role of chance 25/98 (25.5%) endometriosis women with a concomitant autoimmune disease (cases) were compared with 73/98 (74.5%) endometriosis patients without autoimmunity (controls). The mean age was 37.36±3.63 and 36.93±3.79 (p=.623) in cases and controls respectively. The mean number of oocytes retrieved was higher in cases (5.78±4.07) than in controls (3.82±2.69;p=.041); similarly, cases showed an higher number of embryos (2.13±1.93 vs. 1.19±1.37;p=.041) and blastocysts (1.89±2.02 vs. 0.85±1.61;p=.041) obtained. A total of 47 fresh embryo transfer (ET) were performed. Considering all the endometriosis patients, the clinical pregnancy rate (CPR) per cycle was 34.0% (16/47); when stratifying for the presence of autoimmunity the CPR was 23.1% (3/13) in cases, and 38.2% (13/34) in controls (p=.494). Limitations, reasons for caution This is a retrospective study based on data extraction from electronic records of our Fertility Centre. The sample size is limited and some information about past medical history could be missed. Results should be interpreted with caution until validated by future research providing more standardized data collection. Wider implications of the findings: Despite significantly higher numbers of oocytes retrieved and embryos/blastocysts formed, the presence of concomitant autoimmune disease in patients with endometriosis may impair pregnancy rates. Whether this finding is confirmed and whether it could be due to a defect in embryo/blastocysts quality or in endometrial receptivity deserves further studies.

BackgroundCurrent studies on clot characterization in acute ischemic stroke focus on fibrin and red blood cell composition. Few studies have examined platelet composition in acute ischemic stroke clots. We characterize clot composition using the Martius Scarlet Blue stain and assess associations between platelet density and CT density.Materials and methodHistopathological analysis of the clots collected as part of the multi-institutional STRIP registry was performed using Martius Scarlet Blue stain and the composition of the clots was quantified using Orbit Image Analysis (www.orbit.bio) machine learning software. Prior to endovascular treatment, each patient underwent non-contrast CT (NCCT) and the CT density of each clot was measured. Correlations between clot components and clinical information were assessed using the χ2 test.ResultsEighty-five patients were included in the study. The mean platelet density of the clots was 15.7% (2.5–72.5%). There was a significant correlation between platelet-rich clots and the absence of hyperdensity on NCCT, (ρ=0.321, p=0.003*, n=85). Similarly, there was a significant inverse correlation between the percentage of platelets and the mean Hounsfield Units on NCCT (ρ=−0.243, p=0.025*, n=85).ConclusionMartius Scarlet Blue stain can identify patients who have platelet-rich clots. Platelet-rich clots are isodense on NCCT.

BackgroundAntiplatelet therapy is used to prevent stent thrombosis in intracranial stents, but the optimal dose of aspirin is unknown. This study sought to determine whether the degree of platelet inhibition with aspirin is affected by bodyweight as observed through a platelet reactivity assay.MethodsThis is a retrospective review of patients who underwent neurovascular stent placement and had a VerifyNow Aspirin assay result. The primary outcome was the correlation between the VerifyNow Aspirin result, bodyweight, and the initial dose of aspirin. Secondary outcomes included the impact of the VerifyNow P2Y12 result and of weight on the incidence of bleeding or a thrombotic event.ResultsOf the 142 included patients, 62.7% weighed ≥70 kg and 88.7% were initiated on aspirin 300–325 mg daily. 83.8% achieved a therapeutic VerifyNow Aspirin result. There was minimal correlation between the VerifyNow Aspirin result, bodyweight, and aspirin dose (R2=0.02). Between patients who weighed <70 kg versus ≥70 kg, there was no difference in the mean aspirin reaction units (ARU) (449 vs 435, p=0.32) or in the incidence of bleeding (28% vs 17.1%, p=0.14) or a thrombotic event (4% vs 5.3%, p=0.59). No patient experienced stent thrombosis and eight patients experienced in-stent stenosis. In a multivariate analysis, only the VerifyNow P2Y12 result predicted the development of either bleeding or a thrombotic event (p<0.01).ConclusionsBodyweight did not influence the likelihood of obtaining a therapeutic VerifyNow Aspirin result. The clinical utility of obtaining VerifyNow Aspirin assays for this patient population is unknown.
