Published: February 2020

Giant juvenile fibroadenoma occurs in adolescent girls. These tumours become enormous in size and grow rapidly, though these tumours are mostly benign. These patients are almost always treated by breast conserving surgery. Here we present a case having unilateral giant juvenile fibroadenoma with bilateral multiple small fibroadenomas in an adolescent female aged 16years. The diagnosis of the patient was made on clinical examination, USG & FNAC. Confirmatory diagnosis was made by histopathology. We removed the giant one with "Swiss-Roll" procedure and others by simple enucleation. The aesthatic appearence of the breasts were preserved.

Published: February 2020

Background: Bronchodilator {P2selective adrenergic drug-salbutamol) causes bronchodilation and increases the vital capacity, tidal volume and total lung capacity and reduces gas trapping. Use of bronchodilator in patients undergoing Off-pump coronary artery bypass graft (OPCABG) may lead to better preservation of pulmonary function.
Objective: To evaluate the role of bronchodilator on preservation of post-operative pulmonary function in patients who underwent OPCABG.
Methods: This study was conducted on 50 patients randomized into two groups to assess the pulmonary function after off-pump CABG. Among them, 25 patients (group-I) were treated by preoperatively bronchodilator and compared them with other 25 patients (group-II) who were not treated by preoperative bronchodilator. We compared arterial blood gas analysis, duration of total mechanical ventilation, days spent in the surgical ICU and spirometric indices.
Results: Mean±SE value of mechanical ventilation time after operation in group-I was 14.25±0.85 hours and in group-II was 16.88±0.85 hours. Mean±SE value of ICU stay after surgery was 98.64±2.07 hours in group I and 110.56±2.36 hours in group-II. Both results were statistically significant (P=0.042 and P=0.001 respectively). The FVC and FEV1 after admission were not statistically significant (P>0.05). On the day before surgery the values of FVC and FEV1 were increased (more in group-1 who were treated with bronchodilator) and 7th postoperative day the value were decreased (more in group -11 who were not treated with bronchodilator). The results were found statistically significant in between two groups (P<0.05). Significant difference were found in PaO2 and PaCO2 on arterial blood gas analysis at half an hour after extubation and on 1st POD (P<0.05). Mean±SE value of postoperative hospital day in group-1 was 8.88±0.24 days and in group II was 10.14±0.43 days which was found statistically significant (p=0.014). Among post-operative pulmonary complications, in group 1, one (4%) patient was found with pleural effusion and one (4%) patient with atelectasis. but in group-II, one (4%) patient was found with pleural effusion and five (20%) patients were found with atelectasis.
Conclusion: Use of bronchodilator preoperatively in patients who underwent OPCABG with impaired pulmonary function leads to reduced mechanical ventilation time, less ICU stay after surgery, better preservation of pulmonary function, reduced post-operative pulmonary complications and reduced hospital stay.

Published: February 2020

Background: Breast cancer is one of the most common cancers in Bangladeshi women. Breast sacrificing treatment is still now the common practice in our country. Now a day’s breast conservative treatment is the standard treatment of breast cancer without compromising the survival.
Objective: To observe local recurrence and distant metastasis free survival and overall survival of patients with breast cancer.
Methods: Between January 1996 and December 2010, breast conserving treatment was carried out in 237 female patients with breast cancer in different Institutions of Bangladesh. Clinical staging was recorded by physical examination, relevant investigations as well as surgical records. Revised breast conserving surgery was carried out in those who had positive surgical margins or palpable disease. The patients with large but operable cancer or locally advanced cancer were treated by neoadjuvant chemotherapy followed by breast conserving surgery. Systemic adjuvant therapy (chemotherapy and or hormone therapy) and adjuvant radiotherapy were given in all patients. After completion of treatment, the patients were followed up with a standard protocol and data were compiled and analysed.
Results: Among 237 patients who underwent breast conserving therapy 13 patients were excluded from the study for various reasons. Total 224 female patients with breast cancer who followed all the treatment schedules and attended for regular follow up were included in the study. They were between 22- 74 years of age, mean age 42.35 years; premenopausal 152 (68%). Sixty five percent (146 patients) was localized cancer (T1-2N0M0), 31.6% was regional cancer (T1-3N1M0), five cases were locally advanced stage (T4bN12M0) and two metastastatic cancer (T2-3N1M1). All most all (98%) were Infiltrating duct cell carcinoma except four which were Intraductal carcinoma in situ (IDIS). Estrogen and progesterone receptors were positive in 57% , HER2 positive (+++) in 24% of Patients. Lumpectomy/quandrentectomy with/without axillary clearance was done in 158 patients, revised breast conserving surgery in 53 cases, mastectomy in 8 cases and only biopsy done but no surgical treatment in five cases.Chemotherapy was given in 192 patients (86%); adjuvant 122 cases and neoadjuvant 70 cases. Hormone therapy in 182 patients. Radiotherapy: in 222 cases. Follow up period was 4 years to 19 years, median 10 years. Overall survival (OS) and disease free survival (DFS) was 84% and 70% respectively. Local recurrence occurred in 14(6%) cases and distant metastasis in 54 cases (24%). Conclusion: Breast conserving treatment was satisfactory for appropriate case selection and optimized therapy. Survival was no way worse than breast sacrificing treatment.

Published: February 2020

Breast cancer is the second common cause of cancer death in women of our country. Treatment of breast cancer depends on a number of parameters known as pathological and biological prognostic markers. Knowledge of the tumour grade would avoid under treatment of high grade carcinomas and over treatment of low grade carcinomas. Out study evaluated the feasibility of a grading system on FNA of duct cell carcinoma (NOS) and its ability to predict the histologic grade of the surgical specimens. The two widely practice grading system; Robinson’s cytological grading and Scraff Bloom Richardson histological grading system were utilized for this purpose. Various reports quote varied reproducibility, ranging from 50 to 90% correlation between histologic and cytologic grade. In this study, the correlation between histologic and cytologic grade is 86.3%. In this study association between grading by FNAC and histology was statistically highly significant (χ2=27.66, df=1, p<0.05) sensitivity 100% and specificity 58.33%. Maximum correlation was noted in grade-I. Out of 53 cases 46 showed correlation between histologic and cytologic grading, only 7 cases showed no correlation. Histologic grade were higher than cytologic grade and maximum were within one grade difference. The reasons for discrepancies between cytologic and histologic grades appear to be due to lack of histologic parameter of mitosis in cytology. In this study, a total 57 cases of breast lump were selected for FNAC; of them 56 were female and 1 male. Out of 57 cases, 44 cases had duct cell carcinoma (DCC) and 13 cases had atypical finding such as small cells, inconspicuous nucleoli. Fifty three cases were diagnosed as DCC and lobular carcinoma by histopathological study. After confirmation of the diagnosis of breast cancer by histopathological examination ER, PR determination by immunohistochemistry was done in all 53 cases of breast cancer. FNAC has good sensitivity (85.29%) and very high specificity (100%). It can replace the open biopsy in the majority cases of clinically malignant disease.

This article discusses the scope of computer ontologies. A classification of the main problems is given, for the solution of which it is advisable to use the ontological approach. Examples of the use of ontologies in various fields of human activity related to knowledge-based systems are given. The scope of application of computer ontologies is discussed in this article . A classification of the main problems is given, for the solution of which it is advisable to use the ontological approach. The areas of application of ontologies are identified as following:

Designing knowledge-oriented systems, which refers to the creation, development, implementation, interaction with users of such objects as knowledge bases, databases and data warehouses. Besides, the same area includes the integration of existing information repositories, even with a very different data structure.
Knowledge management (decision making systems).The usage of the ontological approach allows to raise information management technologies to a new level: to introduce the technology of providing explanations to the user about the management process, which can reveal the essence of the situations and their causes, as well as to justify the proposed action scenarios. That is, to provide human-machine dialogue that allows to communicate in a natural language.
Semantic technology of information search and the ability to build search results using ontological classifiers. This use of ontologies enhances the relevance and continentity of search results. It provides contextual search capabilities, making the most of the natural language vocabulary display.
Classification tasks: the classification structure (taxonomy) is an integral part of any ontology, we can talk about the presence of ontology elements in special classifications and indexing systems (for example, in library classification codes).
Support for linguistically oriented information technologies, that is, providing solutions to complex text processing tasks by organizing a system of interactions of various levels of text processing, including the ontological level associated with the construction of a semantically adequate model of the subject area and various linguistic levels associated with linguistic properties and relations of subject objects area.
Support for transdisciplinarity, namely the formation of common conceptual spaces, providing an adequate understanding of the information exchanged by experts in various fields of human activity.

Examples of using ontologies in various spheres of human activity related to systems based on knowledge, such as education, the creation of the Semantic Web, etc are given.
