Haptoglobin-related protein as a serum marker in malignant lymphoma

A novel serum 21 kDa haptoglobin-related protein (Hpr) was investigated in patients with malignant lymphoma, to evaluate its correlation with clinical and histologic features at presentation and its possible role as a tumor marker for patient outcome. One hundred fifty eight serum samples were taken from 88 patients with non-Hodgkin’s lymphoma (n=58) and Hodgkin’s disease (n=30) at presentation and in the course of follow-up. Sera from 61 healthy volunteers served as normal controls. Serum Hpr levels in the lymphoma patients (median 430xl0³ u/ml, range 0-4000xl0³) were significantly higher than in the control group (median 68xl0³ u/ml, range 0-180xl0³) (p=0.0001). Higher median Hpr values were detected in patients with advanced disease (p=0.013), “B” symptoms (p=0.029) and in males (p=0.053). There was also a significant correlation between Hpr and erythrocyte sedimentation rate (p=0.028). Serial determinations showed a significant decrease of the initial Hpr values obtained after treatment in 41 patients, 38 of whom achieved complete remission. In the follow-up period additional Hpr measurements were taken from 17 patients. Three of them eventually relapsed, and showed increased Hpr levels at the time of relapse. Hpr levels remained low in 11 of 14 patients who maintained complete remission, and increased in three. In conclusion, serum Hpr is a new serum tumor marker of potential use in the clinical setting of lymphoma. This work is dedicated to the memory of Dr. Arie H.

Pattern of ocular injuries in stone pelters in Kashmir valley

PurposeTo describe the pattern and types of ocular injuries in stone pelters in Kashmir valley during recent turmoil.DesignCross sectional study.MethodsSixty patients with different types of eye injuries were assessed between June–September 2010 and initial visual acuity was recorded. The injuries were classified according to Systems for Classifying Ocular Injuries (OTCS) and Ocular Trauma Score (OTS) was calculated in order to estimate the probability of follow-up visual acuity range.ResultsMost of the victims (75%) were young boys between 16–26 years with a mean age of 20.95, 95% of cases were males. The main cause of injury was stones (48.3%) and pellets (30%) besides rubber bullets, sling shots and tear gas shells.Most of the open-globe injuries due to stones were of Type B and A, Grade E, Zone II and III with Afferent Pupillary Defect (APD) in 30% of the cases. Closed-globe injuries were mostly of Type A, Grade C and D and Zone II and III.Most of the open-globe injuries due to pellets were of Type D, Grade D, Zone II and APD in 33.3%. Pellets Intra Ocular Foreign Body (IOFB) was in 41.6%. Most of the closed-globe injuries were of Type A, Grade D and E and of Zone III.Overall OTS of 1 was calculated in 16.6% and 3 in 53.3% of the cases.ConclusionIn stone pelting demonstrations eye injuries can result in visually significant trauma. Injuries due to pellets are mostly perforating and pellet IOFB, and both tend to have a very poor prognosis. OTS can be used to estimate visual prognosis.     

Short-term course and outcome of treatments of pleural empyema in pediatric patients: repeated ultrasound-guided needle thoracocentesis vs chest tube drainage

BACKGROUND: Several reports have suggested that early chest tube drainage (CTD) may not be necessary in the treatment of severe pleural empyema (PE) in pediatric patients if appropriate antibiotic therapy and supportive care are provided. OBJECTIVES: A prospective open study to compare the short-term course of two treatment protocols of severe PE in pediatric patients. STUDY DESIGN: One group of 32 patients was treated with early insertion of a chest tube for CTD, and a second group of 35 patients was treated by a repeated ultrasound-guided needle thoracocentesis (RUSGT). The severity of the empyema was assessed by chest radiograph, the amount of fluid drained, the number of days the patient had experienced a fever, and the duration of antibiotic treatment. RESULTS: No significant differences were found between the two groups (RUSGT vs CTD) in all of the following measurements: mean (plus minus SD) duration of a temperature > or = 39 degreesC, 6.2 +/- 2.4 vs 6.5 +/- 1.8 days, respectively; mean duration of a temperature > or = 38 degreesC, 9 +/- 3.9 vs 8.2 +/- 4.5 days, respectively; fluid drained, 35.1 + 23.8 vs 30 +/- 28.2 mL/kg, respectively; duration of antibiotic treatment, 30 +/- 13.2 vs 30.2 +/- 7.3 days, respectively; and length of hospitalization and home IV treatment, 22 +/- 7.6 vs 24.2 +/- 7.5 days, respectively. A failure to respond to treatment occurred in three patients in the RUSGT-treated group and in five patients in the CTD-treated group. The failure to respond occurred in the RUSGT-treated group only in those patients with very large empyemas that caused mediastinal deviation. CONCLUSION: The treatment of PE by RUSGT is as efficacious as CTD, unless PE causes mediastinal deviation.
