Teenagers were selected by convenience sampling technique from selected schools of Dhaka city. Data were collected by face-to-face interviews using a semi-structured questionnaire. Data analysis was done by IBM SPSS software and quality of data was ensured in all steps of the study. Ethical issues were maintained strictly.\u0000Results: Out of the 382 teenagers, 55.5% were female. Mean age of the teenagers was 15.82 years. Most frequently reported symptoms were fatigue (16.2%), headache (11.3%), and sleeping problems (10.7%). Statistical analysis indicated that fatigue was significantly increased in female teenagers (AOR=1.84, p=0.042) and teenagers from middle and upper social class (p=0.005), headache was significantly associated with female teenagers (AOR= 3.42, p=0.002), and sleeping problem was associated with duration of CP use ≥6 hours/day (AOR=3.36, p=0.003). Palpitation was associated with duration of CP use/day (For 4-5 hours: AOR=4.05, p<0.001; and for ≥6 hours: AOR=3.28, p<0.005) and depression was associated with years of CP usage >1 year (AOR=2.43, p=0.015).\u0000Conclusion: The study revealed factors that were associated with potential negative effects of cell phone use on well being of teenagers.

The outcome of surgery predictors is sometimes biased. Fusion and stabilization in such cases are unnecessary in many situations. There is still a debate to decompress only versus fusion in low-grade listhesis. Fusion and stabilization in the aged lumbar spine should have clear indications.\u0000Objective: To assess whether the fusion is necessary in lumbar spinal stenosis in selected cases or not and to create a new scoring system among the patients of low backache in Bangladeshi people.\u0000Method: A total of 120 cases were observed retrospectively from 2012 to 2018 in Comfort Hospital, Dhaka, Bangladesh. And 40 more cases data will be collected in the upcoming study period of 6 months. To assess the study we will conduct a survey. In previous cases, the patients had undergone three types of surgeries (Laminectomy, Unilateral approach, and Fusion surgeries). ODI and Swiss score were used for assessment of functional outcome. A new scoring system has been made for patients who may be benefited from fusion or non- fusion surgeries.\u0000Results: In retrospective data, there were 80 male and 40 female patients. Maximum patients were between 41 to 50 years. 59.17% were heavy workers and 66.67% were smoker. Maximum patients (59.17%) had undergone unilateral surgical approaches and 18.33% undergone fusion surgeries. 98.33% patients had satisfactory outcome in our study. In our hybrid scale, the pain status showed, 52.50% had moderate pain, 22.50% had mild pain, 20% had severe pain and only 5% had very severe pain. Maximum participants having low back pain were below 30 years old and 65% lift weight more than 25 kg. The total pain score was significant in our correlation test. The Cronbach's Alpha (.784) was significant in Bangladeshi socio- demographic population.\u0000Conclusion: The outcome of such a study will help to know either fusion surgeries in selected cases are effective for lumbar spinal stenosis or not.

Serum levels of VEGF-A were determined by using ELISA method. ROC curve was plotted to achieve the best cutoff value of serum VEGF. The Mann-Whitney test was used to compare the VEGF distribution across sub-groups of patients.\u0000Result: A statistically significant difference in the levels of serum VEGF level was observed between benign and malignant ovarian tumor patients. Ovarian cancer patients had a higher preoperative median S. VEGF level of 753.8 pg/ml than that of benign ovarian masses (median 241.8 pg/ml; p value 0.001).

Blood samples were collected after taking informed written consent and data were collected in a predesigned data collection sheet. The IL-10 gene polymorphisms IL-10 (819T/C), IL-10 (1082A/G) and IL-10 (592C/A) were detected by Polymerase chain reaction- Restriction fragment length polymorphism (PCR- RFLP) method at Department of Microbiology and Immunology, BSMMU, Dhaka.\u0000Results: According to BASDAI score, 14 patients were in inactive disease group and 24 patients were in active disease group. The homozygous CC genotype and C allele of IL-10 (-819T/C) were found significantly higher in patients than control group (p=0.022 and p=0.045 respectively).

Infection and bleeding are the leading cause of death during induction chemotherapy in childhood ALL. So, proper knowledge about anticipated infection and bleeding are very important during this period. But the duration of clinical remission and recovery of peripheral blood count during induction chemotherapy is not well reported in literature.\u0000Objective: The aim of the study was to determine the time of attainment of clinical remission and recovery of peripheral blood count after initiation of induction chemotherapy and to determine if the duration of clinical remission and peripheral blood count recovery differs between therapeutic risk groups.\u0000 Methods: This prospective observational study was conducted from January 2021 to December 2021 in the Department of Paediatric Haematology and Oncology, BSMMU. Newly diagnosed admitted Eighty-Six ALL of both sexes aged 1 to 17.9 years were included. After commencing chemotherapy, physical examination was recorded every day until clinical remission and complete blood count (CBC) was recorded one to two days interval until peripheral blood count recovery. The number of packed red blood cell (PRBC) and platelet transfusions and the number of days of intravenous antibiotics were recorded.\u0000Results: Mean duration of clinical remission, complete Hemoglobin (Hb), Absolute neutrophil count(ANC) and platelet recovery was 8.4 ± 4.5 days, 25±7.9 days, 23.3±5.6 days and 21.8±6.4 days respectively (p<0.01). Time to attain partial recovery of platelet was 14.0±4.9 days in high risk and 19.2±5.3 days in standard risk group.

Time to attain partial recovery of ANC, number of days with I/V antibiotics and duration of treatment interruption were higher in high risk group.\u0000 Conclusion: Time of clinical remission was similar between risk group. Platelet recovery occurred earlier than Hemoglobin (Hb) and absolute neutrophil count (ANC) recovery. Transfusion and supportive care requirement were more in high risk group during induction chemotherapy.

Rifampicin (RIF) resistance has been used as a surrogate marker for MDR-TB diagnosis, but level of isoniazid (INH) resistance and associated resistance conferring mutations for INH in rifampicin-resistant TB cases are little known. Objective: The objective of this study was to determine level of isoniazid resistance and associated resistance conferring mutations in rifampicin resistant Mycobacterium tuberculosis (MTB) in sputum samples. Methods: A total 53 RIF resistant MTB isolates in sputum, detected by Xpert-MTB RIF assay were enrolled in the study. Culture positive samples were tested by BACTEC MGIT 960 system and level of isoniazid resistance was determined, defined as minimum inhibitory concentration of INH of >0.4 µg/mL and 0.1-0.4 µg/mL as high level and low level INH resistance respectively. Distribution of mutation in katG (codon 315) and inhA promoter (-5, -8, -15 and -16) genes by Real-time PCR among the different degrees of INH resistance was investigated. Results: Among the growth positive isolates, 68.8% of the resistant isolates had high level INH resistance, where katG was found to be the prominent mutation, with or without combined with inhA mutation. Positive predictive value (PPV) of katG mutation was 84.6% in detecting a high level of INH resistance. Low level resistance was present in 31.3% isolates, conferring mutation in inhA and katG in equal percentage (40%), but no detectable mutations were found in 20% low level INH resistant MTB isolates. The PPV of inhA mutation was 33.3% in detection low level resistance. Conclusion: Most of the INH resistant isolates conferred high level resistance and were associated with katG mutation. Evaluation of level INH resistance before using high dose INH will help to avoid dose dependent toxicity and to determine an appropriate treatment regimen.
