Abstract: A retrospective review of the cases of 180 patients who had 198 acute open fractures of the tibial shaft and were admitted to a multiple-trauma referral center over a three-year period revealed an incidence of accompanying compartment syndrome of 9.1 per cent (eighteen fractures in sixteen patients). Each of the eighteen compartment syndromes was documented by measurements of intracompartmental pressure that were obtained by the saline-injection technique, and all were treated by four-compartment fasciotomy. The incidence of compartment syndrome was found to be directly proportional to the degree of injury to soft tissue and bone; this complication occurred most often in association with a comminuted, grade-III open injury to a pedestrian. The physician must maintain a high index of suspicion to detect a compartment syndrome in the patient who has multiple trauma, as its clinical signs and symptoms may be masked by a closed injury of the head or the need for ventilatory support or prolonged anesthesia for other surgical procedures.
Which is the apt title for the abstract? option1: Compartment syndrome in open tibial fractures. option2: Postchemotherapy esophagitis: the endoscopic diagnosis and its impact on survival.
answer:

Abstract: Placement of an unheated miniaturized oxygen electrode against the palpebral conjunctiva permits noninvasive measurement of tissue oxygen tension. In this study, the relationship between conjunctival oxygen tension (PcjO2) and standard cardiorespiratory variables was examined during a sequential resuscitation protocol after acute hemorrhage. Anesthetized dogs were rapidly bled to a mean arterial pressure of 40 mm Hg and then retransfused with the shed blood in a stepwise fashion. PcjO2 fell to 2% of control values after hemorrhage and did not return to prehemorrhage values until more than 90% of the shed blood had been reinfused. PcjO2 was among the last set of cardiorespiratory variables to return to control values during resuscitation and was the last noninvasive variable to normalize. The ratio of PcjO2 to arterial oxygen tension decreased from a prehemorrhage value of 0.76 +/- 0.05 (SEM) to 0.02 +/- 0.003 after hemorrhage, and did not increase to values greater than 0.50 until resuscitation was more than 90% complete. Conjunctival oxygen monitoring may play an important role in assessing the adequacy of resuscitation after acute hemorrhage.

Abstract: We studied thyroid growth-blocking activity in immunoglobulin G (IgG) fractions of serum from 24 patients with primary myxedema, 24 patients with goitrous Hashimoto's thyroiditis, and 18 normal subjects by measuring the ability of their IgG to inhibit TSH-induced [3H]thymidine incorporation into DNA in a rat thyroid cell line, FRTL-5. Both groups of patients were receiving T4 when studied. [3H]Thymidine incorporation induced by 0.1 mU/ml bovine TSH was significantly inhibited by the addition of 2 mg/ml IgG from patients with primary myxedema (P less than 0.01), while it was not affected by IgG from the normal subjects or 23 of the 24 patients with goitrous Hashimoto's thyroiditis. IgG from patients with primary myxedema also inhibited the [3H]thymidine incorporation induced by Graves' IgG, but not that induced by forskolin, cholera toxin, (Bu)2cAMP or phorbol-12-myristate-13-acetate. The inhibition of TSH-induced [3H]thymidine incorporation by IgGs from patients with primary myxedema was significantly correlated with their inhibitory activities against both TSH-induced cAMP generation and TSH binding (P less than 0.001). These data indicate that these growth-blocking antibodies are directed against the TSH receptor and might be one of the causes of the thyroid atrophy in patients with primary myxedema.
