Extensive prolongation of rat renal allograft survival following donor or nonspecific transfusions and concomitant immunosuppressant

We report here a marked beneficial effect upon rat renal allograft survival transplanted across a strong histocompatibility barrier (BN----LEW) by pretransplant concomitant donor-strain blood transfusion (DST) and CsA treatment. Comparisons between recipient groups treated with pretransplant nonspecific blood (NST) and concomitant cyclosporine (CsA) or azathioprine (Aza) administration were also made. LEW recipients receiving only a BN renal allograft survived for a geometric average time of 8.9 days. Recipients receiving 1 ml of donor blood at weekly intervals, each week for three weeks prior to transplantation, demonstrated a geometric mean survival time (GMST) of 40.5 days. Recipients receiving this same regimen and concurrent CsA cover (5 mg/kg/day) starting 7 days prior to the first transfusion with discontinuation 5 days prior to transplantation showed extensive prolongation (greater than 100 days). Recipients treated with only CsA cover survived for a GMST of 34.4 days. LEW recipients receiving 1 ml of nonspecific blood at weekly intervals (DA, BUF, WKY, respectively) each week for 3 weeks prior to transplantation were prolonged to 27.7 days. Recipients treated with this same regimen while under CsA cover also demonstrated extended prolongation (greater than 100 days). Recipients receiving multiple donor blood transfusions under Aza (2 mg/kg/day) cover demonstrated lesser prolongation (22.8 days). Recipients receiving the multiple nonspecific blood protocol under Aza cover showed similar prolongation (38.6 days). Recipients treated only with Aza did not show prolonged survival (9.3 days). These differences in survival were considered significant among the 9 transplant groups as determined by ANOVA (P less than 0.001). The majority of recipient groups showed relatively poor renal function over their life spans, independent of whether prolongation occurred. Yet, renal function in the NST or particularly the DST groups covered by pretransplant CsA, demonstrated the best renal function in our laboratory over many years of investigations using the BN----LEW combination. In conclusion, there was a dramatic synergistic beneficial effect of prior multiple DST or NST specific to CsA, as opposed to another immunopharmacologic agent, Aza.     

Percutaneous removal of residual intrahepatic stones

In the Orient there is a high frequency of residual intrahepatic stones after biliary tract surgery. Percutaneous removal of residual intrahepatic stones was attempted in a group of 74 patients. Stones were exclusively intrahepatic in 57 patients, whereas 17 patients also had stones in the common bile duct. Biliary strictures were present in 60 cases (81%). A combination of techniques was used, including preshaped angulated catheters, irrigation-suction, balloon dilation of strictures, and crushing of large stones. In 36 cases all stones were removed and in 14 cases most stones were removed, for a success rate of 67.6%. Biliary stricture was the factor most often responsible for failure.     

Suction–curettage with combination of two different cannulae in the treatment of axillary osmidrosis and hyperhidrosis

Objective  To investigate the efficacy and safety of suction–curettage with a combination of two different cannulae for treatment of axillary osmidrosis and hyperhidrosis.
Design  Retrospective analysis of patients who underwent surgery from September 2004 to September 2006.
Setting  Outpatient clinic for hyperhidrosis at a university-affiliated hospital.
Subjects  Sixty-five patients who were treated for axillary malodor and hyperhidrosis.
Interventions  Patients were sequentially treated with Fatemi and Cassio cannulae.
Main outcome measures  Demographic data, severity data (assessment of malodor), degree of satisfaction, sweating, hair growth, scarring, recurrence and complications.
Results  Sixty of the 65 patients (96.9%) had excellent to fair results, and only 2 patients (3.1%) had poor results. Complications occurred in 4 patients (6.2%). Recurrence occurred in 3 patients (4.6%).
Conclusions  This simplified and inexpensive method resulted in a high success rate with low complications and high satisfaction with minimal scarring and rapid recovery.     

Primary Vibrio vulnificus bacteremia in a liver transplant recipient after ingestion of raw oysters: caveat emptor.

Vibrio vulnificus is responsible for severe infections in chronically ill patients. Organ transplant recipients are also at risk for severe infections due to V vulnificus. We report here the first case of V. vulnificus primary bacteremia due to raw shellfish consumption in a liver transplant recipient. All transplant patients should be cautioned against consuming uncooked seafood and warned about the risk of severe Vibrio infections from seemingly innocuous wounds acquired in a salt water environment.     

Impulsive and premeditated aggression: a factor analysis of self-reported acts.

Although aggression research in general has been hampered by a lack of objective measurements of aggressive acts, two types of aggressive acts, impulsive vs. premeditated, have been studied extensively in recent years. These two types of aggression have been primarily measured by structured or semi-structured interviews. The current study was designed to assess the construct validity of these two types of aggression using a self-report questionnaire which included items gleaned from the content of interviews used in past studies. For this study, 216 college students assessed their own aggressive acts rather than answering general questions about aggression. The students were not significantly different from normative sample groups on self-report measures of impulsiveness, aggression, and anger/hostility. A PCA factor analysis with a promax rotation of the items on the self-report questionnaire identified four factors: impulsive aggression; mood on the day the act occurred; premeditated aggression; and agitation. Thus, impulsive and premeditated aggression are independent constructs which exist in varying degrees among these 'normal' persons in a non-clinical sample. Impulsive aggression was characterized in part by feelings of remorse following the acts and by thought confusion. Premeditated aggression was related to social gain and dominance.     

High 2-Deoxy-2[F-18]fluoro-<Emphasis Type="SmallCaps">D</Emphasis>-glucose Uptake on Positron Emission Tomography in Hibernoma Originally Thought to be Myxoid Liposarcoma

Purpose The purpose of the study is to describe the rare tumor on 2-deoxy-2[F-18]fluoro-d-glucose (FDG) positron emission tomography (PET).Procedure A 33-year-old male was diagnosed with high uptake lesion on FDG-PET scanning, which was found to be hibernoma on excision.Results Hibernoma, originally confused with liposarcoma based on its PET and computed tomography presentation, was excised and correctly identified by pathology.Conclusion Although found to be benign, radiological and FDG-PET scanning results were indistinguishable from malignancy, and biopsy is required to exclude neoplasm.
