ABSTRACT
Introduction Primary care interval is the time duration from a patient's first presentation to the final diagnosis. Ewing's sarcoma is a rare small round blue cell bone tumor originating from neuroectoderm and undifferentiated neuroepithelial cells, having an annual incidence of approximately one case per million in the United States. In this study, we analyzed the age pattern among patients diagnosed with Ewing's sarcoma undergoing management, along with associated features including involved site, regional lymphadenopathy, and distant metastasis at the time of presentation and their correlation with the primary care interval. Methods This is a cross-sectional study carried out at the Oncology department of a Tertiary Care Government Hospital in Karachi, Pakistan. The duration of our study was from January 2020 to December 2020. During this period, all patients with proven diagnosis of Ewing's sarcoma between ages 10 years and 65 years were included in the study. All the participants of the study were divided into groups, based on the age and site of the tumor. Results A total of 895 cases of bone cancer were reported. Among these, 147 cases (16.4%) had Ewing's sarcoma. Of these patients, 88 were male (60%) while 59 (40%) were female. The mean age of patients was 18.9 ± 3.2 years. Ewing's sarcoma most commonly occurred during 15 to 20 years of age. The most common region involved was lower limb (n=76, 52%) followed by upper limb (n=63, 43%) followed by pelvis (n=8, 5.4%). Conclusion The peak time for the occurrence of Ewing's sarcoma is from 15 years to 20 years of age. Regional painful swelling is the most common presenting feature in our study population. Factors causing a prolonged primary care interval include early age of onset, non-specific clinical presentation, and insufficient knowledge of the primary care physician, which results in poor prognosis. Hence, it is important to consider Ewing's sarcoma as a differential on the first presentation especially in the high-risk age group.
ABSTRACT
Objectives The objective of this study was to determine the awareness among healthcare professionals regarding stethoscopes as a source of nosocomial infections, their cleaning practices in this regard before or after examination, and to find out about the existence of any guidelines and accountability criteria issued by the hospitals in this regard. Methodology A descriptive cross-sectional study of 243 healthcare professionals using non-probability convenience sampling was done to include consultants, residents, final-year medical students, and nursing staff and excluding medical students from pre-clinical years as well as doctors of those departments with infrequent use of a stethoscope. The study was conducted for a period of nine months at tertiary health care facilities of Rawalpindi and Islamabad. A self-administered structured questionnaire was used for data collection. Results Participants from both genders included 54 participants (22.2%) from the final year, 48 (19.8%) house officers, 106 (43.6%) postgraduate trainees, nine (3.7%) specialists, and 26 (10.7%) nurses. A total of 210 (86.4%) were aware of stethoscopes as a source of nosocomial infections. Among participants, 23 (9.5%) cleaned their stethoscope per patient, 50 (20.6%) did it daily, 48 (19.8%) did it weekly, 41 (16.9%) did it monthly, 12 (4.9%) participants cleaned it six-monthly while 69 (28.4%) respondents had never cleaned their stethoscope. Almost 127 participants (52.3%) used alcohol wipes to clean their stethoscopes, 11 (4.5%) used a wet cloth, six (2.5%) used tissue paper. Sixty-one (24.9%) agreed that the hospital issued protocols for the decontamination of stethoscopes while 189 (77.8%) did not. A total of 241 (99.2%) believed that there were no accountability criteria set for the assessment of the cleanliness of stethoscopes in their hospitals. Conclusion A majority of the participants were aware of stethoscopes being a source of nosocomial infections and believed in cleaning stethoscopes regularly. However, a majority of the participants believed that their hospital did not issue any protocols for the decontamination of stethoscopes. Further research can expand our recommendations.
ABSTRACT
Primary squamous cell carcinoma (SCC) is a rare entity that usually arises from the malignant transformation of a mature cystic teratoma, an endometrioma, or a Brenner tumor. The de novo occurrence of the pure variety in the absence of a prior lesion is the rarest type, and it arises from the metaplasia of the surface epithelium of the ovary. Because of its rarity, a definitive treatment protocol for treatment is not yet available. We present a case of pure primary SCC of the ovary that was managed by surgery followed by chemotherapy.
ABSTRACT
Background: Sarcoidosis is an inflammatory disease that affects multiple organs in the body, especially the lungs and lymph nodes. The coexistence of sarcoidosis and breast cancer has been reported, but the coexistence of both diseases in the same patient often leads to misdiagnosis. Case: We report a case of a 36-year-old woman who presented with concerns of a lump in her left breast along with pain and discharge from the nipple. On examination a 3-cm hard and tender mass was noted in the upper medial quadrant of the left breast with no palpable axillary lymph nodes. The patient was diagnosed with an infiltrating ductal cell carcinoma of the left breast with T2N0M1 Stage IV disease, due to positive mediastinal lymphadenopathy on positron emission tomography scan. The biopsy of mediastinal lymph nodes allowed us to diagnose sarcoidosis and correctly stage her disease as T2N0M0 Stage IIA breast cancer. The patient underwent lumpectomy followed by adjuvant chemo radiotherapy and hormonal therapy - corticosteroids given for sarcoidosis up to 1 year. The patient is doing well 18 months later without recurrence of disease. Conclusion: The simultaneous occurrence of both diseases in the same patient is the risk for misdiagnosis and mismanagement, therefore it is of utmost importance to correctly stage the disease with appropriate investigations and histologic confirmation prior to initiate the treatment for breast cancer.
