Comparative Analysis of Coronal Sealing Materials in Endodontics: Exploring Non-Eugenol Zinc Oxide-Based versus Glass-Ionomer Cement Systems.

The proper closure of the access cavity between appointments during endodontic treatment is paramount and relies on temporary fillings. This systematic review evaluates the effectiveness of zinc oxide-based materials and glass-ionomer cement (GIC) as temporary coronal sealers after root canal treatment in extracted human teeth. Three databases were searched to identify randomized clinical trials that examined the sealing properties of various temporary sealing materials using dyes or stains as indicators. A total of seven in vitro studies that fulfilled the eligibility criteria were critically analyzed. These indicated significant variations in the relative sealing ability of the coronal breach of endodontically treated teeth, either by zinc oxide or GIC-based materials. While GIC-based material (e.g., Fuji IX and Fuji II) exhibited superior sealing of single-rooted teeth, zinc oxide-based material (e.g., Cavit, Coltosol, Caviton) also showed promising attributes. Resin-modified GIC formulations displayed enhanced physical properties, yet challenges related to adhesive failure and shrinkage during polymerization were observed. Zinc oxide-based materials have demonstrated superior coronal sealing effectiveness over certain GIC in controlled settings. Their premixed nature ensures consistent application and hygroscopic properties improve cavity sealing. However, the focus on dye penetration tests for microleakage in vitro may not fully represent the risk of bacterial infiltration. Thus, in vivo studies are crucial for validating these findings in clinical contexts.

Tracheobronchomegaly (Mounier-Kuhn syndrome) and Bronchiectasis as rare manifestations of Homocystinuria.

Homocystinuria (HCU) is a rare autosomal recessive inherited disorder usually diagnosed in childhood. It is characterized by a deficiency of the enzyme that converts homocysteine to cystathionine. The accumulation of homocysteine leads to abnormalities in the ocular, skeletal, cardiovascular, and central nervous systems. HCU shares several clinical features with Marfan syndrome; however, respiratory system involvement in HCU is uncommon and rarely reported. Bronchiectasis has been previously reported in a few cases of HCU, and it was attributed mainly to fibrillin deficiency. This case describes a young girl diagnosed with classical HCU since childhood who presented with a chronic productive cough and was initially misdiagnosed as bronchial Asthma. However, upon further evaluation, she was eventually diagnosed with tracheobronchomegaly (TBM), or Mounier-Kuhn Syndrome, and bronchiectasis based on the computed tomography (CT) scan of chest findings. To our knowledge, this is the first reported case of TBM and bronchiectasis in HCU. We believe that fibrillin degeneration may be the key to understanding this unusual association in HCU.

Depression and anxiety among hypertensive and diabetic primary health care patients. Could patients' perception of their diseases control be used as a screening tool?

OBJECTIVES: To measure the frequency and identify risk factors of depression and anxiety among diabetic and hypertensive primary health care (PHC) patients. Also to assess whether patients' perception of their chronic diseases control and sleep disturbance could serve as screening tools for depression and anxiety. Methods: This cross-sectional study of 368 PHC patients was conducted in AlKhobar city, Kingdom of Saudi Arabia between April and May 2015. Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 were used as diagnostic tools for depression and anxiety. Results: Frequencies, cross-tabulations and logistic regression tests were performed. Patient's perception of chronic diseases control was significantly associated with the presence of depression and anxiety, while it was not seen in the tested disease control (glycated hemoglobin less than 7% and blood pressure less than 140/90 mm Hg). Sleep disturbance has a high specificity (98.9%) in screening for depression. Overall prevalence of depression or anxiety was 57.3% and detected cases was 23%. Depression comprise 48.7% (39.8% mild, 7.1% moderate, 1.8% severe). Anxiety comprise 38.4% (25.1% mild, 8.8% moderate, 4.4% severe). Co-existence of both disorders was 29.5%. Sleep disturbance, weight change, and low income had an independent significant effect on depression and anxiety. Conclusion: Having no sleep disturbance can rule out 98.9% of depression and anxiety cases.  Patient's feelings should be considered in chronic diseases health care plans. Depression or anxiety among diabetic and hypertensive patients have a high morbidity, but with low detection rate.

Outcome of 234 pregnancies in 140 renal transplant recipients from five middle eastern countries.

OBJECTIVE: To study the pregnancy and offspring outcomes in postrenal transplant recipients. METHODS: This is a retrospective case-note review study investigating the outcome of 234 pregnancies in 140 renal transplant recipients from five different Middle Eastern countries. RESULTS: Of the overall pregnancies 74.4% were successful albeit with high prevalences of preterm and Caesarean deliveries (40.8% and 53%, respectively). The mean serum creatinine did not rise significantly during pregnancy in the group as a whole but did so in patients who had serum creatinine of or above 150 micromol/L at the beginning of their pregnancies. The mean birth weight was (2,458 g) with 41.3% of the newborns being of low birth weight (<2,500 g). The prevalences of stillbirths were 7.3% and of spontaneous abortion was 19.3%. Preeclampsia and gestational diabetes were observed in 26.1% and 2% of pregnancies, respectively. CONCLUSIONS: In the presence of good allograft function, the majority of pregnancies in renal transplant recipients have a good outcome but with increased incidence of preeclampsia, reduced gestational age, and low birth weights. Patients with baseline serum creatinine of above 150 micromol/L have an increased risk of allograft dysfunction resulting from the pregnancy.
