EFFECT OF ENLARGED ADENOIDS AND TONSILS ON BLOOD OXYGEN SATURATION IN AL BAHA, SAUDI ARABIA.

INTRODUCTION: The adenoids and palatine tonsils, part of the lymphoid tissue, act as a first line of defense protecting the lower airways and gastrointestinal tract. Adenotonsillar hypertrophy in children may lead to airway obstruction. This study aims to demonstrate the association between adenotonsillar hypertrophy and decreased blood oxygen saturation. METHODS: A retrospective cohort study was conducted among children aged 7-12 years with adenotonsillar hypertrophy and obstructive symptoms, admitted to King Fahad Hospital and Prince Mishari Hospital, Saudi Arabia, for tonsillectomy between July 2023 and January 2024. Exclusion criteria included respiratory diseases, cardiac disease, nasal polyps, nasal septum deviation, chest wall abnormality, and lower airway diseases. The control group included 56 healthy children. An otolaryngologist determined the severity of airway obstruction using the tonsil size. Oxygen saturation was measured using pulse oximetry. The determinants of oxygen saturation were assessed using multiple linear regression, with significance set at p<0.05. RESULTS: The study included 357 participants, with an even age distribution between 7-9 years (49.6%) and 10-12 years (50.4%), and 52% males. Diagnoses included adenoid hypertrophy (30%), tonsil hypertrophy (35%), both conditions (19%), and the control group (16%). Tonsil sizes ranged from Grade 1 (48%) to Grade 4 (8.4%), with 17% normal. The median oxygen saturation was 96.0% for the adenotonsillar hypertrophy group and 99.0% for the control. Oxygen saturation levels differed significantly across groups (p<0.0001), with lower median saturation in hypertrophy groups than controls. Males had a lower oxygen than females (estimate: -0.338, 95% CI [--0.640, -0.036], p=0.028). Adenoid hypertrophy (estimate: -3.863, 95% CI [-5.241, -2.484], p<0.001), tonsil hypertrophy (estimate: -3.631, 95% CI [-5.053, -2.208], p<0.001) and having both conditions (estimate: -3.777, 95% CI [-5.3.7, -2.247], p<0.001) was associated with lower oxygen saturation. Grade 1 tonsil size was associated with an increase in oxygen saturation (estimate = 2.905, 95% CI [1.616, 4.194], p<0.001). In contrast, Grade 4 tonsil size was linked to lower oxygen saturation (estimate=-4.848, 95% CI [-6.367, -3.329], p<0.001). Grades 2 and 3 were not significantly associated with changes in oxygen saturation. CONCLUSION: Adenotonsillar hypertrophy is significantly associated with decreased blood oxygen saturation and related cardiopulmonary complications in children. Early adenotonsillectomy may be of benefit in preventing these complications and improving oxygen saturation levels.

Fingertips squamous cell carcinoma: Treatment outcomes with surgical excision and full thickness skin graft.

Fingertips squamous cell carcinoma is a rare disease. An often missed or delayed diagnosis, the affected finger could result in an amputation. Our aim is to focus on the results of surgical excision of fingertips squamous cell carcinoma. Between 2005 and 2011, eighteen fingers on eight patients with a mean age of 62.5 years underwent surgery. The surgical excision margin was 5mm and the defect was covered by a full thickness skin graft. Three fingers were revised for having a non-secure margin with an enlarged excision and two fingers were amputated at the distal phalange. The diagnosis is often missed or delayed, resulting in an amputation of the affected finger. Aesthetic outcomes range from very good to good satisfaction except for one, which was bad.

Catastrophic antiphospholipid syndrome with concurrent thrombotic and hemorrhagic manifestations.

Antiphospholipid syndrome (APS) is a distinct autoimmune prothrombotic disorder due to pathogenic autoantibodies directed against proteins that bind to phospholipids. APS is characterized by arterial and venous thrombosis and their clinical sequelae. Catastrophic antiphospholipid syndrome (CAPS) is a rare and often fatal form of APS characterized by disseminated intravascular thrombosis and ischemic injury resulting in multiorgan failure. Rarely, intravascular thrombosis in CAPS is accompanied by hemorrhagic manifestations such as diffuse alveolar hemorrhage. Here, we report a 43-year-old woman who presented with anemia, acute gastroenteritis, abnormal liver function tests, bilateral pulmonary infiltrates, and a systemic inflammatory response syndrome. The patient developed respiratory failure as a result of diffuse alveolar hemorrhage followed by acute renal failure. Laboratory tests disclosed hematuria, proteinuria, and reduced platelet count. Microbiologic tests were negative. A renal biopsy demonstrated acute thrombotic microangiopathy and extensive interstitial hemorrhage. Serologic tests disclosed antinuclear antibodies and reduced serum complement C4 concentration. Coagulation studies revealed the lupus anticoagulant and autoantibodies against cardiolipin, beta 2-glycoprotein I, and prothrombin. High-dose glucocorticoids and plasma exchange resulted in rapid resolution of pulmonary, renal, and hematological manifestations. This rare case emphasizes that CAPS can present with concurrent thrombotic and hemorrhagic manifestations. Rapid diagnosis and treatment may result in complete recovery.
