    ABSTRACT: Objective: To determine and investigate the effect of bacterial contamination on implant survival rate. Method: A prospective cohort study was conducted on patients planned for dental implantation who agreed to participate in the study. Levels of bacterial contamination was estimated before and after saline rinses in immediate implantation/augmentation (study) and late implantation (control) sites. Samples from the socket were plated onto appropreate agar plates for total bacterial counts and on selective agar plates for Aggregatibacter actinomycetemcomitans (Aa) and Porphyromonas gingivalis (Pg) counts. The clinical situation of the augmented / implanted area was followed up for 1-3 years. Results: Thirty two patients participated in the study and were devided to either experimental (N=17) or control group (N=15). Significant differences were found between the two groups before and after the saline rinse (P<0.005). Significant positive correlations were found between prevalence of the periopathogens Aa and Pg and bleeding on probing and presence of oral malodor. None of the cases has revealed evidence for late infection of the graft/implant. All augmentations and dental implantations have survived during the follow up period (3 years). Conclusions: A high level of bacterial contaminationwas found in clinically infected extraction sockets, with higher levels in the mandible. Meticulous debridment and saline rinse can lower the contamination level. Immediate implantation or augmentation in clinically and microbiologically infected sites can be treatment of choice, without engdangaring survival rates, as long as debridment and rinses are performed.

    ABSTRACT: Objectives : to evaluate the survival rate of dental implants replacing failed implants in grafted maxillary sinuses by lateral approach compared to replacing failed implants in non grafted posterior maxillae. Methods: retrospective analysis of 75 patients undergone re-implantation in posterior maxillae. The study group composed of 40 patients who had failed and replaced implant in grafted posterior maxilla by lateral approach sinus floor augmentation sites, and a control group composed of 35 patients who had failed and replaced implant in pristine sites of posterior maxilla. The collected date were analyzed for mean ± standard deviation (SD) using SPSS 10.0, SPSS Chicago IL, with a significant level of 5% using T-Test, Mann Whitney, Chi-Square test and survival with Kaplan-Meier. Results: In a follow up period of 5 years in average, there were no failure of the secondary implants, so 100% survival in the replacing implants (75 implant). The main reason for failure was lack of osseointegration, and it was more pronounced in the study group. (p=0.027) A higher rate of early failure was found in the study group. (p=0.038) Conclusions: According to the current research, the high survival rates of dental implants replacing failed implants in posterior maxilla with or without sinus floor augmentation- 100% survival for 5 year follow up- leads to the conclusion that the maturation level of bone graft may play a role in the early failure of the dental implant and leads to higher survival rate in the replacing implant. With the limitations of this research, we can conclude that dental implant failure after sinus floor augmentation should not prevent the practicioner from second attempt.

    ABSTRACT: Chemotherapy induced neutropenic fever can be safely treated with oral antibiotics. However, guidelines are based on studies that focused on patients with solid tumors. To evaluate the effectiveness and safety of oral antibiotics in non-Hodgkin's lymphoma (NHL) patients with low risk neutropenic fever. The files of all NHL patients who were hospitalized due to low risk neutropenic fever were reviewed. All patients who were hospitalized in our department were treated with oral amoxicillin - clavulanic acid and ciprofloxacin. Patients who were hospitalized in the other departments received parenteral antibiotics. The two modalities were compared for the course and outcome of the febrile disease. The files of 48 patients were reviewed. Most patients had intermediate grade NHL, stages III-IV. Thirty-three patients with 44 episodes of neutropenic fever were treated parenterally, while 15 patients with 19 episodes received oral antibiotics. The two policies had equally successful outcomes (59% in the parenteral group and 74% in the oral group, p=0.270). There was no difference in the rate of mortality, serious complications, secondary infections, no response to initial antibiotic regimen, and antibiotic regimen intolerance. The study confirms that oral ciprofloxacin and amoxicillin - clavulanate is a valuable alternative to the parenteral treatment combination in the management of NHL patients with chemotherapy-induced low risk febrile neutropenia.

    ABSTRACT: 46-year-old patient with acute myeloid leukemia (AML) whose disease manifested as fever, chills and dry cough is reported here. Despite broad antibiotic coverage he remained acutely ill with spiking fever, shaking chills, and hypoxemia. His initial chest radiograph was normal but chest computed tomography (CT) scan disclosed bilateral focal infiltrates. Hypoxemia and severe thrombocytopenia precluded invasive diagnostic procedures. A thorough epidemiological investigation revealed that before becoming acutely ill the patient smoked daily tobacco mixed with marijuana from a "hookah bottle". While waiting for tobacco and "hookah water" cultures, we started antifungal therapy. Resolution of fever and hypoxemia ensued after 72 hours. Tobacco cultures yielded heavy growth of Aspergillus species. We suggest that habitual smoking of Aspergillus-infested tobacco and marijuana caused airway colonization with Aspergillus. Leukemia rendered the patient immunocompromised, and allowed Aspergillus to infest the lung parenchyma with early occurrence of invasive pulmonary aspergillosis. Physicians should be aware of this potentially lethal complication of "hookah" and marijuana smoking in immunocompromised hosts.

    ABSTRACT: Bone marrow (BM) involvement in low-grade non-Hodgkin's lymphoma (NHL) has a clear impact on patients' survival. The standard practice is morphological examination of BM biopsy at diagnosis. The clinical significance of flow cytometry (FC) analysis of BM aspirates is largely unknown. The medical charts of 70 low-grade NHL patients, who underwent BM biopsy and FC analysis between 1994 and 2004, were reviewed. Forty-three patients (61.4%) were BM+ by morphology, while in those without morphological involvement by lymphoma FC was positive in 9 (BM-FC+, 12.9%) and negative in 18 (BM-FC-, 25.7%). The median treatment-free period was shorter in the BM+ and BM-FC+ groups compared with the BM-FC- group (1 and 4 months vs. 31 months, respectively) (log-rank test, P = 0.0195). The median survival time was not reached for the BM-FC- patients, whereas for BM+ and BM-FC+ patients it was 129 and 89 months, respectively, with no significant difference between them [the difference between the BM-FC- and the two other groups was statistically significant (log-rank test, P = 0.029)]. The outcome of low grade NHL in patients who had BM involvement by FC alone or by morphology was similar. If confirmed, these findings suggest a modification in the workup and management of localized low grade NHL.

    ABSTRACT: Monoclonal gammopathy of undetermined significance is defined by the presence of: low serum and/or urine monoclonal protein level; less than 10% plasma cells in bone marrow; normal serum calcium, creatinine and hemoglobinlevels; and no bone lesions on full skeletal X-ray survey. To study the necessity of bone marrow examination for the diagnosis and clinical course of MGUS. We retrospectively screened the medical records of all patients in whom monoclonal protein was found in the serum during 2001-2002 in the medical laboratories of Meir Medical Center. Asymptomatic patients who had serum monoclonal immunoglobulin G < 3.0 g/dl or IgA < 2.0 g/dl or IgM < 1.0 g/dl without anemia, renal failure, hypercalcemia or any bone lesions on skeletal survey were eligible. Full records of patients who were evaluated in the hematology clinic were available (group 1). The remaining patients were followed by their family physicians; thus we had access only to their electronic files including laboratory results and new diagnoses (group 2). Demographic and clinical parameters as well as clinical course werewere evaluated. Both groups (57 and 255 patients, respectively) had similar demographic, laboratory and clinical characteristics. Bone marrow examination was performed in 30 of 57 patients (group 1): 16 were normal, 8 had an excess of normal plasma cells, and 6 had excess of pathologic plasma cells. However, only in two of the latter six could a diagnosis of multiple myeloma be established. All group 1 patients were followed for 22 +/- 11 months and onlytwo developed overt multiple myeloma. During the same period, 6 of 255 patients (group 2) were diagnosed as multiple myeloma and 3 as MGUS in other hospitals. The rest had a stable course with no change in their laboratory values. Our findings suggest that bone marrow examination should not be performed routinely in patients who fulfill strict clinical and laboratory criteria of MGUS.

    ABSTRACT: In young women treated for intermediate-high-grade non-Hodgkin's lymphoma with CHOP (cyclophosphamide, adriamycin, oncovine and prednisone), there is insufficient data concerning gonadotoxicity or the need for fertility-preserving measures. The aim of the present study was to evaluate the fertility status in the first complete remission of women who were treated for aggressive non-Hodgkin's lymphoma. A cohort of 36 women with aggressive non-Hodgkin's lymphoma in first remission, who were treated in five university-affiliated hospitals in Israel, was evaluated. All women were aged younger than 40 years at diagnosis and received frontline protocols, including cyclophosphamide and adriamycin, mostly CHOP. Menstrual cycle characteristics, as well as pregnancies before the diagnosis, during treatment and in first complete remission, were evaluated. The patients' mean age at the diagnosis was 28 +/- 7 years (range 17 - 40 years). All patients were treated with chemotherapy, although 10 patients received additional radiotherapy. Follow-up time at first complete remission was 84 +/- 48 months. Before diagnosis, all patients had menstrual cycles, which were regular in 31 (86%). Three patients received gonadtropin-releasing hormone analogs, whereas nine received contraceptive pills together with cytotoxic treatment. During treatment, 18 patients (50%) had amenorrhea, six (17%) had irregular menstrual cycles, and 12 (33%) continued their regular cycles. All but two women resumed menses in the first complete remission, and these were regular in 22 (61%) patients. In 63% of patients, the menstrual cycle recovered within 3 months of the discontinuation of chemotherapy. Eighteen patients (50%) became pregnant during the first complete remission. There was no significant difference between those patients who received fertility-preserving measures versus the remainder concerning regular menstrual cycles recovery or pregnancies. The two patients who developed amenorrhea were 40 years old at the time of diagnosis. In conclusion, the rate of gonadal dysfunction is very low among young, CHOP treated, non-Hodgkin's lymphoma female patients. Fertility-preserving techniques are not needed for women aged younger than 40 years and should probably be reserved for those who are at high risk for gonadal toxicity.

    ABSTRACT: Alopecia and bone marrow suppression are prominent effects of doxorubicin-containing chemotherapy. The aim of the study was to validate our preliminary clinical observation that the lack of alopecia in Hodgkin lymphoma patients may predict poor response to chemotherapy and low rate of bone marrow suppression. Sixty-six patients with Hodgkin lymphoma were reviewed. They were treated between 1991 and 2001 with at least 4 courses of doxorubicin-containing chemotherapy (MOPP/ABV or ABVD) in 2 university-affiliated hematology departments. Thirty-four patients exhibited complete or near complete alopecia, and 32 retained their hair or had only minimal hair loss. The 2 groups were compared by response to treatment and episodes of bone marrow suppression. Alopecia was associated with a high rate of remission (OR 8.48, 95% CI 2.77-25.95), episodes of neutropenia (OR 3.55, 95% CI 1.28-9.84), leukopenia (OR 1.83, 95% CI 0.68-4.92), delays in scheduled treatments (OR 1.61, 95% CI 0.607-4.30), or number of courses with dose reduction (OR 1.63, 95% CI 0.56-4.74). Significantly more patients with alopecia had at least 1 of these parameters (88% versus 62%, P=0.015; OR 4.50, 95% CI 1.27-15.94). In conclusion, in patients with Hodgkin lymphoma treated with doxorubicin-containing chemotherapy, the absence of alopecia may predict poor response to treatment along with fewer episodes of bone marrow suppression. The absence of alopecia in such patients should alert clinicians to the possibility of treatment failure.

    ABSTRACT: Multiple myeloma represents a malignant proliferation of plasma cells derived from a single clone. It is well known that alkylating agents are capable of inducing myelodysplastic syndromes (MDS) and acute myelocytic leukemias (AML). This risk of both diseases in patients with multiple myeloma has been estimated to be 10-20% after 10 years. We aimed to evaluate the time course and the type of genetic abnormalities in melphalan-treated patients in the chronic stage of the disease. We applied fluorescence in situ hybridization methods with probes to 5q31 and 7q31 to mononuclear peripheral blood leukocytes of 18 melphalan-treated patients and compared the results to those of 8 untreated myeloma patients. We found three patients (17%) with a 5q31 deletion in their peripheral white blood cells, but no 7q31 deletion. These findings suggest that 5q- occurs before the overt development of MDS/AML and raise important concerns regarding long-term treatment of myeloma patients with alkylating agents. Also, the performance of cytogenetic evaluation should be considered before autologous transplantation. The clinical and biological implications of these findings should be evaluated in larger clinical and laboratory studies.

    ABSTRACT: Peripheral odontogenic tumours (POT) are rare benign focal overgrowths of the oral soft tissue, usually occurring in the gingiva. Between 1996-2000, 6 out of 406 excised gingival lesions were diagnosed as POT (1.5%). Tumours included peripheral odontogenic fibroma (2 patients), peripheral calcifying odontogenic cyst (2 patients), peripheral ameloblastoma (1 patient), and peripheral calcifying epithelial odontogenic tumour (1 patient). Review of the literature reveals that peripheral odontogenic fibroma and peripheral ameloblastoma were the most common POT. The purpose of this article was to analyse the clinical data of these tumours according to the presented cases and the literature review, to elucidate typical features of each tumour type and enhance easy identification.

    ABSTRACT: In this study, we used spectral karyotyping (SKY) and fluorescence in situ hybridization (FISH) as complementary techniques for the analysis of two therapy-related secondary myelodysplastic syndrome (t-MDS) cases with complex karyotypes, previously analyzed by G-banding. Different types of SKY's cytogenetic contributions include confirmation of G-banding results, identification of partially characterized rearrangements, identification of marker chromosomes unidentified by G-banding, and detection of cryptic reciprocal translocations. In particular, the ability of SKY to clarify a number of markers led to the comprehension of clonal evolution. The common aberration found in these two t-MDS cases was the fragility of chromosome 5 and monosomy of chromosome 18. We clearly present that the use of SKY combined with conventional G-banding analysis and FISH has assisted in the identification of important chromosomal events that may play a key role in the development of t-MDS.

    ABSTRACT: Complete remission can be achieved in 60-80% of adults with diffuse aggressive non-Hodgkin's lymphoma. However, 20-40% of them will subsequently relapse. Nevertheless, formal follow-up guidelines for recurrence detection have never been advocated. We analyzed the pattern of relapse in 30 patients with intermediate- and high-grade non-Hodgkin's lymphoma and the value of intensive protocol for relapse detection. This protocol includes frequent follow-up visits, complete blood count, and serum LDH tests along with annual chest, abdominal, and pelvic CT scans. The median duration of complete remission was 12 months. Twenty-five relapses (83%) were suspected after an interim history and/or physical examination, whereas only 5 relapses (17%) were detected by routine radiographic or laboratory follow-up studies. The majority of relapses (19/30) were detected in sites that included the sites of prior disease. For the first 12 months of complete remission, the estimated cumulative save in charge for a follow-up strategy, based on regular visits in the hematology clinic and performing laboratory and radiologic studies as clinically indicated, is 44% of the cost of a routine intensive evaluation. A reliable and cost-effective follow-up method for non-Hodgkin's lymphoma patients in complete remission should include frequent history and physical examination. Complementary studies should be performed according to clinical indications.

    ABSTRACT: The purpose of this study was to evaluate the incidence of postoperative bleeding in patients treated with oral anticoagulant medication who underwent dental extractions without interruption of the treatment and to analyze the incidence of postoperative bleeding according to the International Normalized Ratio (INR) value. The 249 patients who underwent 543 dental extractions were divided into five groups: Group 1 with INRs of 1.5-1.99, Group 2 with INRs of 2-2.49, Group 3 with INRs of 2.5-2.99, Group 4 with INRs of 3-3.49 and Group 5 with INRs>3.5. The INR was measured on the day of the procedure. Local haemostasis was carried out with gelatin sponge and multiple silk sutures. Of the 249 patients, 30 presented with postoperative bleeding (12%): Group 1, three patients presented with bleeding (5%), Group 2, 10 patients (12.8%), Group 3, nine patients (15.2%), Group 4, five patients (16.6%) and Group 5, three patients (13%). The incidence of postoperative bleeding was not significantly different among the five groups. The value of the INR at the therapeutic dose did not significantly influence the incidence of postoperative bleeding. Thus, dental extractions can be performed without modification of oral anticoagulant treatment. Local haemostasis with gelatin sponge and sutures appears to be sufficient to prevent postoperative bleeding.

    ABSTRACT: Chronic lymphocytic leukemia (CLL) is the most common leukemia in humans, with the major cytogenetic aberrations of trisomy 12 and deletion of 13q14. This study examined the influence of these aberrations on general gene replication. The study group included three subgroups: (1) 15 CLL patients, (2) 4 CLL patients with trisomy 12, (3) 3 CLL patients with deletions in 13q14. Five healthy individuals served as a control group. Monocolor fluorescence in situ hybridization (FISH) with probes for c-myc, HER-2/neu, and p53 was applied to lymphocyte nuclei for the evaluation of replication timing. Asynchronous replication (SD) rate was significantly higher in all CLL patients (P < 0.01) when compared to the control group and was even higher in the group of CLL patients with trisomy 12 and 13q14 deletion (P < 0.01). The asynchrony rate was significantly higher in cells with trisomy 12 for all three probes analyzed, compared to "healthy" cells in the same patients (P < 0.001). To conclude, in CLL patients with a chromosomal aberration such as trisomy 12 and 13q14 deletion we were able to demonstrate a high rate of asynchrony of replication. The high correlation between cells with trisomy 12 and SD pattern could reflect direct influence of the aberration on gene replication and cell cycle control.

    ABSTRACT: To evaluate the prevalence of neurological abnormalities in patients with ET and attempt to identify risk factors for neurological complications. Ninety-five patient charts were reviewed from January 1983-July 1999. Seventy patients fulfilled the Polycythemia Vera Study Group criteria for diagnosing ET. Eighteen patients (25.7%) had episodes of neurological impairment, 52 (74.3%) had none. Neurological features-- occlusive cerebrovascular event-9; chronic headache-3 and dizziness-3, mononeuritis multiplex, sinus vein thrombosis and epilepsy-1 each. The interval between diagnosis of ET and occurrence of neurological events ranged from time of presentation (10 patients) to 13 years (1 patient) with a high predominance of females, 88.8% and 55%, respectively. Neurological complications occurred at presentation or during follow-up in approximately 25% of patients with ET. Our observation suggests that further investigation focusing on the possible mechanisms for neurological deficits in females with ET should be considered.

    ABSTRACT: This study analyzed the fate of plates used to correct maxillofacial injuries and defined risk factors that eventually resulted in plate removal. The outpatient clinic files of 108 patients treated with rigid internal fixation after maxillofacial trauma were reviewed. Study variables included age, sex, trauma circumstances, diagnosis, type of fracture, approach to the facial skeleton, presence of teeth in the line of fracture, plate material, site of plates, and reasons for plate removal. Of 204 plates used for fixation, 44 plates (22 percent) were removed. When all factors were considered together, only fracture diagnosis (mandibular body and angle) and plate location (mandibular body and angle) were statistically significant. Only when each factor was considered separately, the approach to the facial skeleton (intraoral) and the type of fracture (comminuted and compound fractures) were statistically associated with plate removal. Selection of favorable plate location, the extraoral approach, and vigilant infection control may reduce plate removal in patients with maxillofacial injuries. Special attention should be given to compound and comminuted fractures of the mandibular body and angle.

    ABSTRACT: Recently, a working-model of a stepwise malignant transformation in the molecular pathogenesis of multiple myeloma (MM) was proposed, involving the tumor suppressor gene TP53 and retinoblastoma gene (RB1) as prominent components of cell cycle control. To further define the role of TP53 and RB1 in disease progression, we retrospectively analyzed by fluorescence in situ hybridization (FISH) cytological material from 16 patients who underwent sequential bone marrow biopsies during the course of their disease. For TP53, no deletions were detected at presentation or during follow-up. It is possible that the patients reported here represent a subset with relatively long survival, and therefore did not demonstrate the TP53 deletions that had been reported in patients with a very poor prognosis. For RB1, monoallelic deletion was demonstrated in nine patients. In each case, the deletion appeared already in the first biopsy analyzed. The presence of a deletion did not affect the rate of tumor progression or the length of follow-up, and thus prognosis. Monoallelic deletions of RB1 appear to be a frequent and early event in the pathogenesis of MM, without obvious relevance for disease progression.

    ABSTRACT: To determine the prevalence of endogenous and exogenous risk factors for venous thrombosis in patients with upper limb deep vein thrombosis (DVT), and to evaluate the risk of clinically detectable pulmonary embolus, recurrent DVT, and postphlebitic symptoms in these patients. A combined prospective and retrospective descriptive analysis of a cohort of patients with upper limb DVT compared with age- and sex-matched patients with lower limb DVT. Internal medicine departments, and hematology and vascular surgery outpatient clinics at a tertiary-care university hospital. Consecutive patients with "spontaneous" upper limb DVT diagnosed between 1989 and 1997 were studied. Twenty age- and sex-matched patients with lower limb DVT admitted to the hospital via the emergency department served as control patients. Eighteen patients with upper limb DVT were studied. An endogenous risk factor (thrombophilia) was present in 11 of 18 patients vs 8 of 20 control patients (p = not significant). In the upper limb group, nine patients had activated protein C resistance, four patients had anticardiolipin antibodies, and two patients had both forms of thrombophilia. Furthermore, 14 of the upper limb DVT patients were found to have an exogenous risk factor for thrombosis compared with 7 of the patients with lower limb DVT (p = 0.01), and 66.6% of patients with upper limb DVT had both an exogenous and an endogenous risk factor for thrombosis vs 15% of patients with lower limb DVT (p < 0.002). No clinically detectable pulmonary emboli occurred among the upper limb DVT patients. Three patients have minor postphlebitic symptoms. Two patients experienced recurrent DVT. In the majority of patients with upper limb DVT that we studied in this relatively small study, exogenous (environmental) or endogenous risk factors for venous thrombosis, or a combination of both, were found. Furthermore, in our patients, these thromboses had a low propensity to cause clinically significant pulmonary embolus and did not cause significant postphlebitic symptoms. Finally, we suggest that anticoagulant therapy for these thromboses may be adequate and that thrombolytic agents and surgical intervention are not routinely indicated.
