Low-Grade Non-intestinal Type Sinonasal Adenocarcinoma: A Case Report.

Sinonasal non-intestinal-type adenocarcinomas represent a rare subset of head and neck cancers with distinct pathological and clinical characteristics. Patients usually present with nasal obstruction, epistaxis, and rhinorrhea. The diagnosis is established through histopathological examination.

Persistent Stapedial Artery in Adhesive Otitis Media: A Case Report.

A persistent stapedial artery (PSA) is a rare embryologic remnant that typically involutes at week 10 of embryogenesis. However, if it is persistent, it may lead to conductive hearing loss and pulsatile tinnitus. It is of utmost importance to identify such an anomaly, as it leads to serious complications intraoperatively if overlooked.

Comparative Study of Complete Blood Count Between High-Altitude and Sea-Level Residents in West Saudi Arabia.

The reduction in oxygen partial pressure at high altitudes leads to diminished oxygen saturation in the arteries, stimulating erythropoietin production and erythropoiesis to restore appropriate oxygenation. While many studies have explored acclimatization to high altitude and its effects on complete blood count (CBC) parameters, our research uniquely examined both male and female healthy individuals, emphasizing the novelty of gender-specific observations. We analyzed 1,160 individuals in Taif (Al Hada), east Saudi Arabia, a high-altitude region, and compared them to 1,044 counterparts in Jeddah, at sea level.

Prevalence of Delayed Eruption of Permanent Upper Central Incisors at a Tertiary Hospital in Riyadh, Saudi Arabia.

Tooth eruption is defined as the axial movement of the tooth from its site of development in the alveolar bone to its functional position in the oral cavity. A delay in eruption can directly affect the accurate diagnosis, overall treatment planning, and timing of treatment. Thus, Delayed Tooth Eruption can have a significant impact on a patient's proper health care.

Effect of hypothyrodism's medication (T4) on implant osstointegration: A case series and literature search.

Introduction: Hypothyroidism reduces the recruitment, maturation, and activity of bone cells, decreasing bone resorption and formation. Several investigations have reported that T4 replacement therapy is associated with a significant decrease in bone mineral density in various skeletal parts, while others have failed to corroborate these results. The present study describes both a literature review and our own experience with dental implants in patients with hypothyroidism undergoing T4 replacement therapy.
