Surgical treatment of strabismus fixus associated with high myopia

A 55-year-old woman had convergent strabismus fixus associated with high myopia. Bilateral medial rectus recession and loop myopexy of lateral and medial rectus muscles was performed. The clinical characteristics and the possible surgical treatment modalities were discussed. This surgery seems effective on both the restoration of dislocation of the eyeball and the improvement of ocular motility.     

Successful Hypothermia Treatment of Hypoxic-Ischemic Encephalopathy in a Neonate with Epidermolysis Bullosa

Despite advances in the neonatal care, hypoxic ischemic encephalopathy in late preterm and term infants remains an important cause of morbidity and mortality. There is lack of data on the application of therapeutic hypothermia in the existence of severe skin lesions. Epidermolysis bullosa is a rare group of inherited conditions which causes blisters in skin and mucosal membranes. In this report, the authors describe a successful whole-body hypothermia treatment of severe hypoxic ischemic encephalopathy in a term newborn with dystrophic epidermolysis bullosa. They observed that therapeutic hypothermia may also be given in newborns with dystrophic epidermolysis bullosa without any complications.     

Thrombotic thrombocytopenic purpura associated with multiple myeloma

Thrombotic thrombocytopenic purpura is a thrombotic microangiopathic disease. Associations with collagen vascular diseases, pregnancy, some drugs, surgical intervention, and infections are documented (known). Malignancy is also one of the known factors associated with thrombotic thrombocytopenic purpura. These malignancies are usually the disseminated solid organ tumors. Hematological malignancies constitute a rare association. Here, we present a patient with thrombotic thrombocytopenic purpura associated with multiple myeloma and discuss the pathogenesis. To our knowledge, this is the first case report of thrombotic thrombocytopenic purpura associated with multiple myeloma.     

Effect of platelet count on secretion capacity: formulization and use of the formulae for evaluation of platelet secretion in thrombocytopenic patients

The correlation between platelet count and bleeding time is nonlinear. The bleeding time prolongs more prominently as platelet count decreases toward 10 000 microl(-1); however, it becomes stable near 100 000 microl(-1). Clinical observations suggest that platelet functional capacity may also play a role in bleeding complications during thrombocytopenia. However, no routine method has been described for evaluation of platelet function during thrombocytopenia. To test if platelet functional capacity is affected by the cell count, as suggested by the platelet count-bleeding time correlation. To evaluate lumiaggregometry as a possible tool for studying platelet functions and prediction of bleeding in thrombocytopenic patients. Collagen-induced ATP release was studied in different dilutions of 22 healthy platelet-rich plasmas. The relationship between platelet count and ATP release was formulized. ATP release was also tested in 24 thrombocytopenic (10 000-50 000 microl(-1). ) patients, and the results were compared with expected levels derived from the formulae. ATP release increased in a cubic fashion as platelet count elevated. ATP secretion values were within normal limits or increased in patients with idiopathic thrombocytopenic purpura. However, some patients with megakaryocyte deficiency had a secretion defect. ATP secretion was decreased in four out of seven patients with bleeding symptoms compared with no persons without bleeding (P = 0.003). Platelet functional capacity is affected by the cell count. Lumiaggregometry is potentially useful in evaluating platelet functions during thrombocytopenia.     

Frontoethmoid sinus osteoma as a cause of subperiosteal orbital abscess

A 65-year-old woman presented with severe periorbital pain and swelling of the left eye, with complete ptosis, proptosis, and conjunctival chemosis. The eye was in a hypotropic position, and activity in the left superior rectus was inadequate. A firm, elastic, 2-cm mass was palpated near the superior orbital rim. Computed tomography revealed a subperiosteal abscess (SPA) at the superior portion of the orbit and a large frontoethmoidal sinus osteoma. After the SPA had been surgically drained and the osteoma completely removed, the patient recovered, with resolution of proptosis, ptosis, and motility limitations. Osteomas of the paranasal sinuses are usually asymptomatic and rarely cause SPA and orbital cellulitis. Therefore, osteoma cases must be closely followed to ensure that early diagnosis and treatment of SPA are successful in preventing severe visual loss and rescuing the patient’s vision.
