Scientific journals are ethically bound to cite Professor Dr. Carl Clauberg's Nazi medical crimes against humanity whenever the eponym Clauberg is used. Modern articles still publish the eponym citing only the rabbit bioassay used in developing progesterone agonists or antagonists for birth control. Clauberg’s Nazi career is traced to his having subjected thousands of Jewish women at the Ravensbruck and Auschwitz-Birkenau death camps to cruel, murderous sterilization experiments that are enthusiastically described by incriminating letters (reproduced here) between him and the notorious Nazi Reichsführer-SS Heinrich Himmler. The experiments were carried out in women’s Block 10 in Auschwitz-Birkenau where Clauberg’s colleague Dr. Josef Mengele worked alongside. After Germany lost World War II in 1945 Mengele fled to South America, where he lived to an old age. Clauberg was caught by Russian soldiers, put on trial in the Soviet Union for his crimes against humanity, and imprisoned in 1948. In 1955 he was repatriated to Germany, once again imprisoned for his crimes, and belatedly expelled from the German Medical Association. To estimate the contemporary usage of the names Mengele and Clauberg, Internet hits were recorded for Clauberg C or Mengele J (with and without adding the term Auschwitz) with the Google and Scirus search engines. The ratios of hits for combinations of these terms reveal that relative to Mengele, Clauberg’s name is barely known. We propose that journals and books printing the eponym Clauberg cite its derivation and reference to the convicted Nazi criminal. The present article can serve for such citations.

Background: Delays in diagnosis and inadequate treatment of acute scaphoid fractures can lead to non-unions, presenting surgeons with unique challenges regarding optimal management.

Objectives: To evaluate the clinical and radiographic outcome of scaphoid non-unions treated with percutaneous screw fixation.

Methods: The study group comprised12 patients with scaphoid non-unions of an average duration of 8.7 months. There were 11 males and 1 female with an average age of 24 years (range 14–47 years). All patients were initially treated with percutaneous screw fixation without bone grafting. A volar percutaneous approach was used in eight patients and a dorsal percutaneous approach in four. Wrist range of motion (ROM) and disabilities of the arm, shoulder, and hand (DASH) questionnaires were used to assess clinical outcomes. Postoperative radiographs were reviewed to assess the fracture union, carpal alignment and screw position.

Results: Eleven of the 12 (92%) fractures united successfully with no additional procedures. These fractures achieved radiographic union at an average of 4 months. One patient with sickle cell anemia required revision fixation, which consisted of repeat percutaneous fixation and bone grafting. In this patient his non-union healed 3 months after the revision procedure. The average DASH score at final follow-up was 6 (range 0–16). Average wrist ROM was extension of 66 degrees (range 50–80) and flexion 71 degrees (range 55–90). None of the patients showed radiographic signs of osteoarthritis, osteonecrosis of the scaphoid, or hardware-related complications.

Conclusions: For scaphoid waist nonunions without collapse, percutaneous fixation without supplementary bone grafting provides satisfactory results with a high union rate, early return of function and minimal complications.
 

Background: Multidrug-resistant tuberculosis (MDR-TB) presents a difficult therapeutic problem due to the failure of medical treatment. Pulmonary resection is an important adjunctive therapy for selected patients with MDR-TB.

Objectives: To assess the efficacy of pulmonary resection in the management of MDR-TB patients.

Methods: We retrospectively reviewed the charts of MDR-TB patients referred for major pulmonary resections to the departments of thoracic surgery at Assaf Harofeh and Wolfson Medical Centers. For the period under study, 13 years (from 1998 to 2011), we analyzed patients’ medical history, bacteriological, medical and surgical data, morbidity, mortality, and short-term and long-term outcome.

Results: We identified 19 pulmonary resections (8 pneumonectomies, 4 lobectomies, 1 segmentectomy, 6 wedge resections) from among 17 patients, mostly men, with a mean age of 32.9 years (range 18–61 years). Postoperative complications developed in six patients (35.3%) (broncho-pleural fistula in one, empyema in two, prolonged air leak in two, and acute renal failure in one). Only one patient (5.8%) died during the early postoperative period, three (17.6%) in the late postoperative period, and one within 2 years after the resection. Of 12 survivors, 9 were cured, 2 are still under medical treatment, and 1 is lost from follow-up because of poor compliance.

Conclusions: Pulmonary resection for MDR-TB patients is an effective adjunctive treatment with acceptable morbidity and mortality.
 

Background: The 20%–60% rate of acute anterior myocardial infarction (AAMI) patients with concomitant left ventricular thrombus (LVT) formation dropped to 10–20% when thrombolysis and primary percutaneous coronary intervention (PPCI) were introduced.

Objective: To test our hypothesis that prolonged anticoagulation post-PPCI will lower the LVT incidence even further.

Methods: Included in this study were all 296 inpatients with ST elevation AAMI who were treated with PPCI (from January 2006 to December 2009). Treatment included heparin anticoagulation (48 hours) followed by adjusted doses of low molecular weight heparin (3 more days). All patients underwent cardiac echocardiography on admission and at discharge. LVT and bleeding complications were reviewed and compared.

Results: LVT formation was present on the first echocardiogram in 6/296 patients. Another 8/289 patients displayed LVT only on their second echocardiogram (4.7%, 14/296). LVT patients had significantly lower LV ejection fractions than non-LVT patients at admission (P < 0.003) and at discharge (P < 0.001), and longer time to reperfusion (P = 0.168). All patients were epidemiologically and clinically similar. There were 6 bleeding episodes that required blood transfusion and 11 episodes of minor bleeding.

Conclusions: Five days of continuous anticoagulation therapy post-PPCI in inpatients with AAMI is associated with low LVT occurrence without remarkably increasing bleeding events.
 

Background: Carbon dioxide is the most widely used gas to establish pneumoperitoneum during laparoscopic surgery. Gastrointestinal trauma may occur during the peritoneal insufflation or during the operative phase itself. Early diagnosis of these injuries is critical.

Objectives: To assess changes in end-tidal carbon dioxide (E_TCO₂) following gastric perforation during pneumoperitoneum in the rat.

Methods: Wistar rats were anesthetized, tracheotomized and mechanically ventilated with fixed minute volume. Each animal underwent a 1 cm abdominal longitudinal incision. A 0.3 x 0.3 cm cross-incision of the stomach was performed in the perforation group but not in the controls (n=10/group), and the abdomen was closed in both groups. After stabilization, CO₂-induced pneumoperitoneum was established at 0, 5, 8 and 12 mmHg for 20 min periods consecutively, each followed by complete pressure relief for 5 minutes.

Results: Ventilatory pressure increased in both groups when pneumoperitoneal pressure ≥ 5 mmHg was applied, but more so in the perforated stomach group (P = 0.003). E_TCO₂ increased in both groups during the experiment, but less so in the perforated group (P = 0.04). It then returned to near baseline values during pressure annulation in all perforated animals but only in the 0 and 5 mmHg periods in the controls.

Conclusions: When subjected to pneumoperitoneum, E_TCO₂ was lower in rats with a perforated stomach than in those with an intact stomach. An abrupt decrease in E_TCO₂ during laparoscopy may signal gastric perforation.
 

Background: The management of sexual assault victims comprises complex medical, psychological, social and judicial care that was previously provided by various disciplines at several distant locations. This novel concept is the delivery of comprehensive care to victims of sexual assault at one location 24 hours a day.

Objectives: To describe the characteristics of sexual assault victims, their assailants, the assault and the treatment, and provide descriptive data on the evidentiary examination.

Methods: We performed a retrospective analysis of the charts of all sexual assault victims presenting to the Regional Israeli Center for Care of Sexual Assault Victims between October 2000 and July 2010. The center, the first in Israel, provides comprehensive care to victims of sexual assault in one location 24 hours a day using a multidisciplinary approach.

Results: The study group comprised 1992 subjects; 91.5% of the victims were females and 8.5% were males, and the age ranged from 1 to 88 years (mean age 22.3 years). Of the 1992 victims, 1635 were single (82.2%), 195 were divorced (9.8%), 141 were married (7.1%), 18 were widowed (0.9%) and 3 were unspecified. The assailant was a stranger in 794 (39.8%) of the cases, someone familiar to the victim in 786 cases (39.0%), a partner in 127 cases (6.4%), a family member in 117 cases (5.9%), someone met via the internet in 53 cases (2.7%), an authority figure in 39 cases (2.0%), and unspecified in 76 (3.9%). In the majority of cases the attack occurred either in the evening or at night (71.7%).

Conclusions: We identified several risk factors for sexual assault that can be used in prevention programs. The sexual assault victim in our study tended to be a young, single woman who was attacked by a familiar assailant in the evening or at night. Our center provides comprehensive care to victims 24 hours a day at one location and includes a team of forensic, psychological, physical and legal specialists.
 

Background: Determining the prognosis of patients with heart failure is essential for patient management and clinical trial conduct. The relative value of traditional prognostic criteria remains unclear and the assessment of long-term prognosis for individual patients is problematic.

Objectives: To determine the ability of clinical, hemodynamic and echocardiographic parameters to predict the long-term prognosis of patients with idiopathic dilated cardiomyopathy.

Methods: We investigated the ability of clinical, hemodynamic and echocardiographic parameters to predict the long-term prognosis of individual patients in a large, representative, contemporary cohort of idiopathic dilated cardiomyopathy (IDCM) patients referred to Johns Hopkins from 1997 to 2004 for evaluation of cardiomyopathy. In all patients a baseline history was taken, and physical examination, laboratory studies, echocardiogram, right heart catheterization and endomyocardial biopsy were performed.

Results: In 171 IDCM patients followed for a median 3.5 years, there were 50 long-term event-free survivors (LTS) (median survival 6.4 years) and 34 patients died or underwent ventricular assist device placement or transplantation within 5 years (NLTS; non-long-term survivors) (median time to event 1.83 years. Established risk factors (gender, race, presence of diabetes, serum creatinine, sodium) and the use of accepted heart failure medications (angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta blockers) were similar between the two groups. Although LTS had younger age, higher ejection fraction (EF) and lower New York Heart Association (NYHA) class at presentation, the positive predictive value of an EF< 25% was 64% (95% CI 41%–79%) and of NYHA class > 2 was 53% (95% CI 36–69%). A logistic model incorporating these three variables incorrectly classified 29% of patients.

Conclusions: IDCM exhibits a highly variable natural history and standard clinical predictors have limited ability to classify IDCM patients into broad prognostic categories. These findings suggest that there are important host-environmental factors still unappreciated in the biology of IDCM.
