“…The mean age of Jordanians affected by non-Hodgkin's lymphoma was reported to be 32.4 years, with 22.5% of patients below the age of 10 [16]. In the present study, the mean age of our patients is 41 years, and only 10% of them are within the first decade of life.…”

During a 10-year period (1976-1985), a total of 596 cervical lymph node biopsies for diagnostic purposes were performed at our institution. Thirty-five percent of these nodes were involved with malignant lymphoma, and 20.5% showed metastatic deposits. Nondiagnostic reactive hyperplastic changes were noted in 23% of the cases. Several other inflammatory and neoplastic conditions were encountered. Comparison of our data with several series from different countries with review of relevant literature are presented.

“…This may be partly explained by the high prevalence of IPSID in these areas. 22,40,41 Among the three groups classified by primary site, histology and clinical stage were different. The gastric group contained a predominance of early-stage, low- grade B-cell lymphomas, most of which were marginal zone lymphomas.…”

Polymer particle agglomeration and melting causing sheet formation in fluidized bed reactors have been reported to occur during olefin polymerization. The cause of this deleterious sheet formation has not yet been established. Infrared and optical imaging were used to study the temporal temperature and size during polymerization of individual commercially active catalyst particles supported on a nylon mesh. Experiments conducted at 2100 kPa confirmed theoretical predictions that the temporal temperature rapidly attains a maximum after the start of the reaction. The magnitude of the temperature rise increases upon an increase of either reactor temperature, initial catalyst particle diameter, catalyst loading, or addition of hydrogen to the feed. The maximum transient temperature rise of single commercial catalyst particle during ethylene polymerization (7.5°C) is lower than that which can lead to local melting and polymer sheet formation. The temperature rise of particle clusters is much higher than that of individual particles, as the cluster acts as a particle with an effective diameter much larger than that of an individual particle. Thus, to circumvent polymer melting it is essential to avoid catalyst particles clustering, which may be caused by electrostatic attraction. The addition of hydrogen to the feed, often used to control polymer properties, significantly increased the initial particle temperature rise (almost double in some cases). © 2008 American Institute of Chemical Engineers AIChE J, 2008

The incidence and clinical characteristics of malignant lymphomas (ML), the most common tumors encountered in the Middle East, vary in different regions. [1][2][3][4][5] This retrospective study analyzed histologically confirmed cases of malignant lymphoma seen in King Fahd Specialist Hospital (KFSH) during an eight-year period (01/01/87 to 31/12/94). The results were compared with data from other regions of the Kingdom and the Middle East. KFSH is a 570-bed regional referral hospital of Al-Qassim region and the majority of malignant disease patients of the region are referred here for further management. Patients and MethodsThe records of 160 consecutive patients of histologically confirmed lymphoma, seen in KFSH between 01/01/87 and 31/12/94, were reviewed. There were 145 Saudis and 15 non-Saudi patients. Twenty-one patients (nine Saudis and 12 non-Saudis) did not have either enough clinical details or pathological material available for inclusion in the study.The patient's age, sex, site of initial presentation and symptoms with duration were all noted. The majority of the patients had undergone a complete staging workup, including hemogram, liver function tests, chest x-ray, abdominal ultrasonography, CT scan of the chest and abdomen, as well as bone marrow examination. Laparotomy was not carried out for staging purposes.Patients were staged according to the Ann Arbor classification. 6 B symptoms were defined as weight loss >10% over six months prior the admission and/or unexplained fever with temperature >38°C and/or night sweats. The histopathology of Hodgkin disease (HD) was classified according to the Rye scheme of classification 7 and that of non-Hodgkin lymphoma (NHL) according to Rappaport 8 and the working formulation. 9 The results were compared by r-test and contingency tables were analyzed by χ 2 test with Yale's correction. ResultsOut of the total of 139 cases included in this study (136 Saudis, three non-Saudis), 87 (62.6%) patients had NHL and 52 had HD (37.4%).Age distribution: Shown in Figures 1 and 2. The age ranged from two to 99 years. The mean age for HD was lower than for NHL (27.9±21.2 years versus 46.8±27.60 years, t=2.3, P<0.05). Patients with the nodular sclerosis (NS) type of HD presented at an earlier age than other types of HD (mean age 21±13.5 versus 33.7±24.9 years, t=2.3, P<0.05).Sex ratio: The male to female ratio of 60:27 (2.2:1) in NHL was higher than 33:19 (1.7:1) in HD (χ 2 =0.23, P>0.5). The NS type of HD was more common in females with a male to female ratio of 1:1.3 (χ 2 =6.33, P<0.05). Histological types: Tables 1 and 2 show the age-related histological types of HD and NHL. In HD, lymphocytic predominant (LP) and NS were more common (57.7%) than mixed cellularity (MC) and lymphocytic depletion (LD) combined (42.3). The majority of NHLs were aggressive lymphomas (Table 3).Presenting symptoms: Awareness of a peripheral Jump was the most common symptom with which our patients presented (93/139, 66.9%), being more common in HD (47/52, 90.4%) than in NHL (46/87, 52.9%) (χ 2...
