https://lmj.ly/index.php/ojs/article/view/146
<p>Tobacco smoking among adolescents remains a critical public health challenge, with profound implications for long-term health outcomes and societal well-being. This study aimed to assess the prevalence of cigarette smoking among school students in Tripoli-Libya and explore the key initiation factors to inform locally tailored prevention strategies. A school-based cross-sectional study was conducted across six randomly selected governmental middle and high schools in one of the largest Municipalities in Tripoli, targeting 379 students aged 10–18 years. A pretested, anonymous, self-administered questionnaire was administered to assess current and lifetime cigarette smoking, sociodemographic characteristics, and self-reported reasons for initiation. Data were analyzed using the SPSS version 22. The total prevalence of current cigarette smoking was 10%, while the prevalence of cigarette smoking ever use was 26.6%. Ever use of cigarette smoking was significantly higher among male students (32%) compared to females (3%). Students in grades ten and twelve had the highest prevalence, followed by those in grade nine. Male gender was a statistically significant factor associated with cigarette smoking (p<0.05). The most common self-reported reasons for cigarette smoking included imitating smokers, curiosity, and expressing masculinity (p<0.05). This study contributes to the growing body of evidence on adolescent cigarette smoking patterns, with higher rates among males and older students, suggesting smoking may symbolize a transition to adulthood.</p>Halima BuniKhaled Elmaghbub

https://lmj.ly/index.php/ojs/article/view/148
<p>The knee joint, as the largest synovial joint in the human body, functions as a pivotal component for lower extremity motion and load bearing. Its intricate anatomy and biomechanics are essential for maintaining stability, mobility, and overall limb function. This chapter will elaborate on the anatomical structures, biomechanical principles, and clinical implications pertinent to the knee, providing a comprehensive framework for board candidates in orthopedics and sports medicine. The knee joint's stability is a product of interacting factors, including ligaments, muscular forces, bony structure, and load. The joint, one of the body's largest and most complex, involves four bones and an extensive network of ligaments and muscles. These elements work together to facilitate movement and bear weight while maintaining stability. Understanding these components is crucial for comprehending knee function and the potential for injury. The interplay between the static and dynamic elements is particularly important in biomechanics.</p>Mohamed Rashed

https://lmj.ly/index.php/ojs/article/view/151
<p>Placenta previa is a severe complication of pregnancy and is the most common cause of postpartum hemorrhage, which often endangers the lives of pregnant women. In patients with malignant placenta previa and placenta accreta, ultrasound can display obvious blood flow changes, such as abnormal blood flow in the placental cavity, abundant blood flow signals, placenta accreta, a thinned echo zone between the uterus and placenta, an enlarged cervix, and thinned myometrium. Color Doppler ultrasound can accurately identify whether it is complete placenta previa. This study was conducted to assess the role of Doppler ultrasound in the diagnosis of invasion of the placental tissue. The study was a retrospective descriptive study conducted at Aljala Maternity Hospital in Tripoli during the years 2020-2021. Among 120 pregnant women were selected from medical files, and a predesigned questionnaire was formed to collect data from patients by simple random sampling methods. The data was coded and analyzed by using SPSS (Statistical Package for the Social Sciences) version 20. All variable results were considered statistically significant with a P value less than 0.05. Among 120 pregnant women who were diagnosed with placental invasion, the mean age group was 29.45 ± 5.345 SD, the minimum age was 18 years, and the maximum age was 45 years. Regarding the obstetric history, the mean gravidity was 3.37 ± 1.942 SD, the mean parity was 1.76 ± 1.559 SD, the mean miscarriage rate was 1.71 ± 0.454 SD, and the mean gestational age at time of diagnosis was 6.21 ± 2.111 SD. Regarding the prior experience with abnormal placentation in previous pregnancy, 66.3% had experienced it. Regarding the Doppler ultrasound approach, 73% of patients had abnormal Doppler findings on assessment. Regarding the prevalence of complications among participants who were diagnosed with placental invasion and the most commonly recognized complications were wound infection and thromboembolism, which both account for 63.5%. On assessing the placental invasion by Doppler ultrasound, this approach had a significant impact on evaluating pregnancy. Therefore, early utilization of Doppler is recommended, particularly in high-risk groups, to evaluate and detect serious health outcomes related to placental invasion.</p>Huda KhalifLaila AlmahdiNasreen OsmanAmel Morgham

https://lmj.ly/index.php/ojs/article/view/152
<p>During the COVID-19 outbreak, health care workers faced significant psychological challenges while fighting the pandemic on the front lines. This research evaluated the mental health of front-line health workers following four years of COVID-19 efforts. This study aimed to investigate the anxiety levels and depression in HCWs in Libya after the COVID-19 pandemic and to assess the main predictors of elevated anxiety levels among them. A cross-sectional study included healthcare workers (doctors and nurses) in Benghazi hospitals who had been working during the COVID-19 pandemic and were willing to give consent. Female nurses reported the highest level of anxiety, followed by doctors. The three most critical variables that may explain the distress level were loss of control or vulnerability, worry for one's health, and the spread of the infection. Strategies for early detection and treatment of depression and anxiety should be developed for medically ill people.</p>Asma AlfallahMohamad Zew

https://lmj.ly/index.php/ojs/article/view/153
<p>Dravet syndrome typically manifests after the first year of life with prolonged febrile and afebrile seizures in previously developmentally normal children. The epilepsy is often refractory to standard anti-seizure medications, and by age two, most children develop epileptic encephalopathy. This retrospective study aimed to identify predictors of treatment response and developmental outcomes, as well as characterise demographic and clinical features in patients with SCN1A mutations. We reviewed clinical records of patients meeting Dravet syndrome diagnostic criteria, extracting data on demographics, clinical phenotype, and treatment history. Seventeen patients were included (male-to-female ratio 0.54:1; mean age 10.03 ± 5.8 years). All had normal birth histories, and 94.1% experienced their first seizure before six months of age, with fever as the precipitating factor in 70.6%. All patients had a history of prolonged seizures or status epilepticus. Initial interictal EEGs were normal in 76.5% during the first two years, and brain MRI was normal in 88.2%. While all children were developmentally normal before seizure onset, 76.5% later exhibited developmental delay and cognitive decline. Seizures worsened in 52.9% of patients when treated with phenobarbital, carbamazepine, lamotrigine, or vigabatrin (as mono- or polytherapy). After genetic confirmation, 94.1% received a combination of stiripentol, valproate, and clobazam, resulting in >50% seizure reduction in 88.2%. Dravet syndrome should be considered in children with refractory epilepsy, infantile-onset recurrent seizures (including febrile seizures/status epilepticus), and normal early development. Genetic testing enables early diagnosis and guides appropriate treatment, improving outcomes. However, no statistically significant predictors of treatment response or developmental outcomes were identified in this cohort</p>Eman AwenSeham Eshrif
