Background and objectives. The relationship between leadership styles and job performance draws considerable attention from recent researchers. The main objective of this study was to determine the impact of leadership style (autocratic, democratic, and laissez-faire) on job performance from nurse’s points of view at Benghazi Medical Centre. Method. This study was a descriptive questionnaire-based study conducted on 100 nurses working at Benghazi Medical Centre, Libya. To analyze the data (mean, standard deviation, ANOVA test were used. Furthermore, multiple regressions and Pearson correlation were used to determine whether a relationship exists between the independent and dependent variables. Result. Of 100, only 60 questionnaires were completed, giving a response rate of 60%. The findings of this study indicated that democratic was the most dominantly used in the hospital, followed by the autocratic and laissez-faire leadership styles. Whereas, the laissez-faire leadership style had a strong positive and significant impact on performance (R2= .333; P < 0.01). Conclusion. Laissez-faire leadership style positively affected nurses’ performance. Future research that might be relevant to be further explored are worth.

Background and objective. Preeclampsia is a multisystemic disorder, which involves the placenta, liver, blood, neurological and cardiovascular systems. It is one of the leading causes of maternal and fetal morbidity and mortality. This study aimed at describing the characteristic features for mothers who had severe preeclampsia and to know the complications during puerperium. Methods. A prospective study conducted over a period from February 2009 up to November 2009 involving 100 pre-eclampsia patients admitted and delivered in Aljalaa Maternity Hospital, Tripoli, Libya. Results. The patients mean age was 33.3 +5.9 years. The mean gestational age at admission time was 36.8+3.2 weeks and 64% of them were term. 58% of the patients with severe preeclampsia had a positive family history of chronic hypertension whereas 42% of patients had a previous history of preeclampsia. 40% of patients were primigravida. The mean systolic blood pressure at admission was 164+15.4 mmHg and the mean diastolic pressure was 113+6 mmHg. The common symptoms were headache, abdominal pain, and blurred vision (54%, 37%, and 31% respectively), whereas 9% of the patients presented with the eclamptic fit. The pregnancy in 66% patients ended by caesarean section, 78% of them were emergency caesarean section. The birth weight of 13% of new-borns was less than 1500 grams. Furthermore, 10% diagnosed with intrauterine fetal death (IUFD) antenatally and 9% died after admission to nursery intensive care unit post-delivery. Conclusion. the effects of hypertensive disorder associated with pregnancy could be prevented by close antenatal care particularly for whose had previous history of preeclampsia. In addition; early recognition and adequate treatment, and timely delivery can prevent preeclampsia and will improve maternal and neonatal outcomes.

Dentigerous cysts are the most common developmental odontogenic jaw cysts, associated with crowns of an Unerupted tooth. Usually, they occur in the second and third decade of life with a male predilection. They are frequently asymptomatic and mostly discovered incidentally on routine dental radiographic examination. Its growth is slow, and can reach a considerable size causing bone expansion and displacement of teeth. Mandibular lower third molars are the most frequently effected teeth; dentigerous cysts involving impacted mandibular canines are rarely reported. Surgical enucleation with extraction of the associated tooth is the standard treatment for dentigerous cyst, marsupialization is recommended for large lesions. We report a rare case of a large dentigerous cyst in a 62-year-old male patient, associated with impacted left mandibular canine, extending from the retro-molar area of left side crossing the midline to the 2nd premolar in the other side, that was successfully treated by marsupialization followed by enucleation and removal of the impacted tooth.

Background and objectives: Tooth extractions are a vital aspect of orthodontic management that enables the orthodontist to achieve good aesthetics and function as well as long term treatment stability for the patient. Extractions may be necessary for various reasons among which are tooth size arch length discrepancy (TSALD), increased overjet and facial profile. The aim of this study was to determine the prevalence, pattern and rationale of tooth extraction among orthodontic patients attending the Orthodontic Unit of the Department of Child Dental Health, University of Port Harcourt Teaching Hospital. Methods. A retrospective study of a cohort of patients who attended one of the outpatient Orthodontic Clinics in the Department of Child Dental Health, University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria between 2011 and 2021. Data was collected from the patients’ records. Results. A total of 175 patients comprising 70(40%) males and 105(60%) females were included in the study. 67(38.3%) patients had at least one extraction. Twenty-eight (41.8%) extraction cases had extraction of the first premolars. Two-unit extractions of the maxillary first premolars (13, 46.4%) was the most frequent extraction pattern. Eight (29.6%) had extraction of primary canines only. Twenty-seven (40.3%) participants had extractions due to increased overjet. Over a third of the patients had extraction of at least one tooth. Conclusion. Two-unit extractions of maxillary first premolar was the commonest extraction pattern. Increased overjet was the commonest reason for extraction.

Background and objectives: Pesticides play an essential role in crop protection, but their overuse caused environmental pollution and harmful effect on different animal body systems, including the endocrine system. The thyroid gland is one of the homeostatic regulators of metabolic activities, which is affected by the elements of the external environment. There are very limited studies on the effect of indoxacarb on the histological architecture and functions of thyroid gland. Therefore, this study was conducted with the aim of examining functionally and histologically of the thyroid gland exposed to indoxacarb. Method: 24 Swiss albino mice male and female were randomly divided into two groups, each group male and female; group I is a control group given orally with 1ml of distilled water and group II orally treated with 120 mg/kg Bw. of indoxacarb daily for 3 weeks. Blood samples were collected from each mouse under anesthetic to determine the thyroid-stimulating hormone (TSH), thyroxine (T4) levels. Thyroid gland histopathology was attained for the evaluation of the indoxacarb effect. Results: The treated mice showed non-significant increase in T4 levels and a significant decrease in TSH levels but there was no significant difference recorded in T4 and TSH levels between sexes. Histologically, the sections of the thyroid gland of the treated group showed empty and irregular follicles, degeneration of the follicular epithelial tissue, and hyperplasia in the lining of some follicles, the capsule with congestion blood vessels. Conclusion: This study concluded that indoxacarb may act as a thyroid gland toxicant.

Aims. The aim of this study was to assess the phytochemical screening and antibacterial effect of the aerial parts of G. alypum cultivated in Libya. Methods. The methanolic extract of G. alypum (at concentrations 100 mg/ml, 300 mg/ml, 500 mg/ml and 700 mg/ml) were tested against 13 different strains of standard bacteria (ATCC) by four different methods; paper disc diffusion method, well diffusion method, broth dilution method and finally study the effect of extract on growth curve of bacterial cell were studied. Results. The results of phytochemical screening revealed the presence of flavonoids, phenols, reducing sugars, tannins, saponins, coumarins, steroids, terpenoids, carotenoids, antraquinones and glycosides. While the results of antibacterial tests showed remarkable inhibition of the bacterial growth, with maximum inhibition on growth of Methicillin Resistant Staphylococcus aureus (MRSA) and Staphylococcus aureus. Moderate effect on growth of Enterococcus faecalis, Bacillus subtilis, Aeromonas hydrophila and Salmonella poona. While, the lowest inhibition showed in Yersinia enterocolitica and Listeria monocytogenes. However, the extract did not have any effect on Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella typhimurium and Klabsiella pneumonia. Conclusion. The methanolic extract of Globularia alypumaerial parts contain the most important constituents with positive results during phytochemical screening, and have antibacterial activity against gram positive and gram-negative bacteria.

Dear Editor, Having read the article “Birth incidence of cerebral palsy in Tripoli, Libya: a population-based study,” published in issue 1 of volume 5 (2021) of Khalij-Libya Journal of Dental and Medical Research, I would like to express some concerns. First, the aim of the study stated at the end of the introduction is “to assess the prevalence and the most common causes for birth cerebral palsy ...” In the methods section, it states that “the study included a total of 200 patients of whom 64 were diagnosed with cerebral palsy,” without describing the inclusion and exclusion criteria for the 200 patients. But no prevalence rate based on the study is given anywhere in the main body of the paper: only the potential causes of cerebral palsy are described.

The recent advent of the COVID-19 pandemic has caused widespread public health concerns and affected provision of health care including the delivery of professional teeth scaling by dental professionals. A cross-sectional online survey of dentists and dental therapists in Rivers State, Nigeria. Questionnaires were distributed to consenting participants using SurveyMonkey. Data were collected on sociodemographic, practice of scaling, and knowledge of recommended guidelines by WHO/CDC on the use of preoperative mouth rinses and Personal Protective Equipment (PPE). Data analysis was done and level of significance was set at p-value < 0.05. Sixty-three dentists and 34 dental therapists participated in this study with a mean age of 35.71±8.58 years. About two-third of the respondents did not perform teeth scaling for their patients during the early pandemic period. Fifty percent of dental professionals in government owned dental clinics performed teeth scaling while none of the private clinic staff did the procedure. The major reason for not performing the procedure was non provision of PPEs followed by fear of contacting the virus. Most (84.1%) of the dentists and 47.1% of dental therapists demonstrated a good knowledge of the recommended guidelines. Almost all (94.7%) of the private clinic staffs demonstrated a good knowledge compared to 65.4% of dental professionals in the government owned clinics. More than half of the dentists and only a few dental therapists performed scaling for their patients during the early period of the pandemic. Dentists and private clinic staffs demonstrated a good knowledge of the recommended guidelines for treatment.

The coronavirus disease 2019 (COVID-19) is a pandemic infectious disease threatening the world, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). While fever, cough, fatigue and shortness of breath are common symptoms, a sudden chemosensory (taste and/or smell) dysfunctions are increasingly reported in asymptomatic individuals that later test positive for COVID-19. The exact pathogenesis of these chemosensory disorders in SARS-CoV-2 infected patients has not yet been clarified. This review aims to provide a brief review of recent evidence for pathological mechanisms of the taste dysfunction in COVID-19 patients. We also discuss the possibility of using isolated sudden onset of taste alterations as an early symptom of SARS-CoV-2 infection that might be very helpful for reducing the spread of COVID-19 through early identification.
