Chronic cholecystitis in elderly patients. Correlation of the severity of inflammation with the number and size of the stones

BACKGROUND: [corrected] The present study focused on cholecystectomized elderly patients and aimed to investigate whether inflammation in the gallbladder wall was associated with the number and size of gallstones, as well as the patients' age. PATIENTS AND METHODS: The present study included 306 cholecystectomized patients aged over 65 years. From the specimens derived from cholecystectomy, the gallstone number, the largest gallstone diameter and gallbladder wall thickness were determined. According to the histopathological examination, chronic inflammation was subdivided into mild-moderate and severe. Univariable analysis and multivariable logistic regression followed. RESULTS: Mild-moderate inflammation characterized 63.4% of the cases and severe inflammation 366%. Solitary gallstones were found in 13.1% of the cases, while multiple gallstones were found in 86.9% of the cases. The largest gallstone diameter was less than 1 cm in the majority of cases (73.2%). The gallbladder wall thickness was associated with the degree of inflammation (p < 0.001, Chi-square). In the univariable analysis, inflammation was positively associated with the diameter of the largest gallstone (p = 0.032, Chi-square), but negatively associated with the number of gallstones (p < 0.001, Chi-square) and patients' age (p = 0.008, logistic regression). The number of gallstones was negatively associated with the diameter of gallstones and positively associated with the patients' age. The diameter of the largest gallstone was negatively associated with the patients' age. In the multivariable logistic regression, the effect of age (OR = 0.95, 95% CI: 0.91-0.99) and solitary gallstones (OR = 2.66, 95% CI: 1.02-6.93) on inflammation persisted, but that of the largest gallstone diameter vanished. CONCLUSION: The elderly population presented mainly with multiple and small gallstones. Solitary gallstones and younger age were the most important predictors for severe inflammation.     

Dissecting the presence of malignant squamous cells in pancreatic cytopathology: A case series

The presence of malignant squamous cells in pancreatic cytopathology is a rare phenomenon that results either from a primary or a metastatic process. Pancreatic adenosquamous carcinoma (PASC) represents the most common variant of pancreatic ductal adenocarcinoma and is associated with a dismal prognosis. Within the period of 2013‐2018, the archives of “Hygeia and Mitera Hospital” were searched for pancreatic cytopathology‐related diagnoses that included the interpretation of “malignant squamous cells present.” All fine needle aspirations (FNAs) of pancreatic lesions, including liver metastases in patients with known pancreatic primaries, were retrieved along with their relevant clinical information. Five pancreatic and two liver FNAs acquired from a total of six patients were reexamined. None of these patients had any documented history of primary squamous malignancy elsewhere. All pancreatic and one of the two liver FNAs showed malignant squamous cells, identified based on either morphology or immunochemistry. The other liver FNA represented a metastatic deposit which comprised of only a glandular component, whereas the associated pancreatic FNA exhibited both squamous and glandular counterparts. Most cases characteristically showed necrosis and keratinization. Of interest, two cases revealed the presence of tumor‐associated giant cells. In conclusion, the presence of malignant squamous cells in pancreatic FNAs could mean the presence of PASC, especially when there is no documented history of a primary malignancy and a complete clinical and imaging workup has been performed. Immunochemistry on cell block material could help to confirm squamous differentiation in the absence of overt keratinization.     

Immunohistochemical expression of estrogen receptors alpha and beta in lobular neoplasia

The designation lobular neoplasia (LN) of the breast includes atypical lobular hyperplasia and lobular carcinoma in situ. Estrogen receptors (ER) play a significant role in breast carcinogenesis. In the present study, ER-alpha and ER-beta status are evaluated in 30 breast tissue specimens from patients whose main lesion was LN. A standard immunohistochemical procedure, using monoclonal antibodies for ER-alpha and ER-beta, was applied to the lesion and the adjacent normal breast tissues, the latter serving as control. In all cases, both receptors were expressed in LN as well as in normal breast ducts and lobules. Concerning ER-alpha, the Allred score and the percentage of ER-alpha-positive cells were significantly higher in LN than in the adjacent normal breast tissue. On the contrary, regarding ER-beta, the Allred score and the percentage of ER-beta-positive cells were significantly lower in LN compared with normal adjacent breast tissue. Greater increase in the percentage of ER-alpha-positive cells was associated with a smaller reduction in the percentage of ER-beta-positive cells and vice versa (Spearman’s rho = −0.5044, p = 0.001). In conclusion, upregulation of ER-alpha and downregulation of ER-beta may represent two discrete molecular events in LN pathogenesis. Of notice, a mutually limiting interaction may exist between the two events.     

INITIAL LOADING (400 μg TWICE DAILY) VERSUS STATIC (400 μg NOCTE) DOSE BUDESONIDE FOR ASTHMA MANAGEMENT

SUMMARY This double-blind study aimed to determine whether superior asthma control is achieved with budesonide (Pulmicort® Turbohaler®) at a loading dose (LD) (400 μg b.d.) for 6 weeks, followed by step down to 400 μg nocte for 12 weeks, compared with a static dose (SD) (400 μg nocte) for 18 weeks. A total of 682 patients (mean peak expiratory flow rate (PEFR) 413 l/min), who demonstrated ≥15% reversibility in PEFR, were randomised into the study. After 18 weeks, patients experienced improvements in morning PEFR (+45 l/min, both groups), symptom score (LD -0.57, SD -0.49, on a scale of 0-3), sleep disturbance (LD -1.21 nights/week, SD -1.06 nights/week) and to-agonist use (LD -1.36 puffs/day, SD -1.06 puffs/day), within both groups (each p=0.0001). At 18 weeks, 82% (LD) and 84% (SD) of patients benefited from no nocturnal wakening in the previous 7 days. Overall, at 18 weeks, asthma control was not significantly different between the groups. After 6 weeks, improvements in morning PEFR (LD +36 l/min, SD +26 l/min) and β₂-agonist use (LD -1.10 puffs/day, SD -0.94 puffs/day) were greater in the loading dose than in the static dose group (each p<0.05). The greater improvement in morning PEFR in the loading dose group was significant by day 7 (p<0.05). While both regimens are equally effective in achieving asthma control at 18 weeks, early clinical advantage is gained with initial loading dose budesonide (400 μg b.d.).     

Comparison of molecular markers expression in vacuum-assisted biopsies and surgical specimens of human breast carcinomas

In this study, we examined whether vacuum-assisted breast biopsy (VABB) specimens provide an accurate immunohistochemical assessment of estrogen receptors (ER), progesterone receptors (PR), c-erbB-2, and p53 proteins.
