Background: Isolated fallopian tube torsion (IFTT) is a rare gynecological entity and its diagnosis is challenging.
Objectives: To compare clinical characteristics, sonographic findings, surgical management, and outcomes of women with surgically verified IFTT compared to those diagnosed with adnexal torsion.
Methods: A retrospective case-control study in a university hospital was conducted. Thirty-four women with surgically verified IFTT between March 1991 and June 2017 were compared to 333 women diagnosed with adnexal torsion within the same time period.
Results: Both groups presented primarily with abdominal pain, which lasted longer prior to admission among the IFTT group (46.8 ± 39.0 vs. 30.0 ± 39.4 hours, P < 0.001). Higher rates of abdominal tenderness with or without peritoneal signs were found in the adnexal torsion group (90.3% vs. 70.6%, P < 0.001). Sonographic findings were similar; however, an increased rate of hydrosalpinx was found among the IFTT group (5.9% vs. 0.0%, P = 0.008). Suspected adnexal torsion was the main surgical indication in only 61.8% of IFTT cases compared with 79.0% in the adnexal torsion group (P = 0.02). Salpingectomy with or without cystectomy was more commonly performed in the IFTT group (35.3% vs. 1.5%, P < 0.001). The leading pathological findings among the IFTT group were hydrosalpinx and paraovarian cysts.
Conclusions: The clinical signs and symptoms of IFTT and adnexal torsion are similar. Although sonographic imaging demonstrating a paraovarian cyst or hydrosalpinx may be helpful in diagnosing IFTT, it is rarely done preoperatively.

Background: Whole-body integrated positron emission tomography / contrast-enhanced computed tomography (PET/CT) scan is increasingly used in cutaneous lymphomas. However, the value of PET/CT in the detection of cutaneous lesions in primary cutaneous B-cell lymphoma (PCBCL) has barely been investigated.
Objectives: To investigate the diagnostic accuracy of PET/CT in tracking cutaneous involvement in PCBCL.
Methods: A retrospective study was conducted on 35 consecutive patients diagnosed with cutaneous B-cell lymphoma according to the World Health Organization classification who were evaluated with PET/CT as the initial staging procedure before treatment.
Results: Thirty-five patients met the study criteria. In two patients extracutaneous disease was detected by PET/CT and CT and confirmed by biopsy. Of the 33 patients with PCBCL, 26 (79%) had small cell PCBCL (18 marginal-zone, 8 follicle-center lymphoma) and 7 (21%) had large cell PCBCL (3 follicle-center, 3 leg-type, 1 indeterminate). PET/CT detected skin lesions in 3 of 26 patients (12%) with small-cell PCBCL as compared to 6 of 7 patients with large-cell PCBLC (86%), a 7.4-fold detection risk (95% confidence interval, 2.4–22, P = 0.004). The PET-positive subgroup was characterized by larger lesion size (P < 0.001) and a higher Ki-67 proliferation index (P < 0.001).
Conclusions: The sensitivity of PET/CT for detecting cutaneous involvement of lymphomas is low for small-cell PCBCL but high for large-cell types, and thus may facilitate therapeutic strategies.

Background: The potential for full rehabilitation following amputation among end-stage renal disease patients is poor.
Objectives: To evaluate the functional outcomes and survival among amputees treated with hemodialysis at the end of the rehabilitation procedure.
Methods: We recruited 46 patients after lower limb amputation. Of these individuals, 19 (41.3%) were treated with dialysis and 27 (58.7%) were non-dialysis-dependent patients (NDDP). Both groups were divided into three sub-groups according to their independence with regard to activities of daily living (ADL) and their ability to walk with prostheses.
Results: The survival of lower limb amputees treated with dialysis was shorter compared to NDDP. Survival after amputation among the NDDP who were fully or partially independent in ADL and with regard to mobility, was longer compared to the non-mobile amputees as with the patients treated with dialysis.
Conclusions: Survival was significantly longer in lower limb amputees NDDP and shorter in patients who did not achieve a certain level of functioning.

Background: Cryptosporidium is a major threat to water supplies worldwide. Various biases and obstacles in case identification are recognized. In Israel, Cryptosporidiosis was included among notifiable diseases in 2001 in order to determine the burden of parasite-inflicted morbidity and to justify budgeting a central drinking water filtration plant.
Objective: To summarize the epidemiologic features of 14 years of Cryptosporidium surveillance and to assess the effects of advanced water purification treatment on the burden of disease.
Methods: From 2001 to 2014, a passive surveillance system was used. Cases were identified based on microscopic detection in stool samples. Confirmed cases were reported electronically to the Israeli Ministry of Health. Overall rates as well as age, gender, ethnicity and specific annual incidence were calculated per 100,000 population in five age groups: 0–4, 5–14, 15–44, 45–64, > 65 years.
Results: A total of 522 Cryptosporidium cases were reported in all six public health districts. More cases were detected among Jews and among males, and mainly in young children, with a seasonal peak during summer. The Haifa sub-district reported 69% of the cases. Most were linked to an outbreak from the summer of 2008, which was attributed to recreational swimming pool activity. Cases decreased after installation of a central filtration plant in 2007.
Conclusions: As drinking water in Israel is treated to maximal international standards, the rationale for further inclusion of Cryptosporidium among mandatory notifiable diseases should be reconsidered. Future surveillance efforts should focus on timely detection of outbreaks using molecular high-throughput testing.

Background: Adenovirus is responsible for 2–7% of childhood viral respiratory infections, 5–11% of viral pneumonia and bronchiolitis. Most are self-limited but may cause severe respiratory infection.
Objectives: To describe adenovirus respiratory infection in immunocompetent children in a pediatric intensive care unit (PICU).
Methods: Children with adenovirus respiratory infection in our PICU from 2007 to 2016 were included. Data were retrospectively retrieved, including background, clinical manifestation, and treatment. Adenovirus was diagnosed by polymerase chain reaction, immune fluorescence, or both.
Results: Of 9397 samples, 956 were positive for adenovirus in children hospitalized during the study period. In total, 49 patients (aged 2 months–11.5 years) were admitted to our PICU, five were immunocompromised and excluded from the study, 19/44 (43%) were referred from other hospitals. Twenty-eight (64%) had underlying conditions, 66% had fever and cough, 11% had conjunctivitis, and 34% received antibiotics before admission. White blood cell counts ranged from 790 to 34,300 (mean 14,600) and 36% had counts above 15,000. Chest X-ray was consistent with viral infection in 77% of patients and normal in three (13.6%). Viral co-infection was found in 9 patients, 7 had presumed bacterial super-infection, and 27 (61.4%) needed mechanical ventilation. Two patients received cidofovir, 33 (75%) steroids, and 37 (84 %) antibiotics. Four patients died.
Conclusions: Adenovirus respiratory infection may cause severe disease necessitating PICU admission and mechanical ventilation, mostly in patients with underlying conditions. Many patients received steroids and antibiotics, which may be unnecessary. Mortality was 9%, mainly among young infants and those with underlying conditions.

Background: Ocular trauma in the pediatric population may lead to cataract formation. Managing traumatic cataracts in a visually immature child is a major challenge and can result in poor visual outcome.
Objectives: To review our long-term surgical experience with childhood unilateral traumatic cataracts.
Methods: A retrospective observational study of children with unilateral traumatic cataracts with minimal follow-up of 5 years was conducted. Main outcomes included final visual acuity (VA) and occurrence of complications.
Results: Of the 18 children included in the study, 83% were male. Mean follow-up time was 12.5 years. Median age at injury was 7.5 years. Eleven patients (61%) presented with penetrating trauma injuries and 7 (39%) with blunt trauma. Sixteen patients (89%) had cataracts at presentation, while in two the cataracts developed during follow-up. Of the 18 total, cataract removal surgery was conducted in 16 (89%) with intraocular lens (IOL) implantation in 14 (87.5%), while 2 remained aphakic (12.5%). Two (11%) were treated conservatively. Long-term complications included IOL dislocation in 5 (36%), glaucoma in 8 (44%), and posterior capsular opacity in 10 (71%). No correlation was found between final visual acuity and the time interval between injury and IOL implantation nor between final VA and age at trauma. However, the final VA did correlate with time of follow-up.
Conclusions: Severe complications occurred in over 30% of the patients during a long follow-up (mean 12.5 years). This finding shows the importance of discussions between the operating physician and the parents regarding the prognosis and necessity of scheduled follow-up.

Background: With the recent introduction of high-sensitivity troponin (hsTn), the incremental benefit of stress myocardial perfusion imaging (MPI) in the evaluation of patients who present to the emergency department (ED) with acute coronary syndrome (ACS) is unclear.
Objectives: To assess the added value of stress MPI in low-risk ACS patients with normal range hsTnI.
Methods: We analyzed all patients who were hospitalized at our medical center from February 2016 to November 2017, who presented with low-risk ACS and underwent stress MPI, and in whom hsTnI was in the normal range after the introduction of hsTnI.
Results: During the study period, 161 patients were admitted with a diagnosis of unstable angina (i.e., ACS with normal range hsTnI) and underwent stress MPI during index admission. The study population included 52/161 patients (31.7%) with low-risk ACS who had no indication for initial invasive strategy. No patients had positive MPI. One patient underwent coronary angiography due to suggestive history; however, he did not have a significant coronary artery disease and had no indication for percutaneous coronary intervention.
Conclusions: In patients with low-risk ACS and normal range hsTnI without additional high-risk features, stress MPI has little additional value for the correct diagnosis and management. Prospective studies are warranted to confirm whether resting hsTnI could serve as a powerful triage tool in chest pain patients in the ED before diagnostic testing and thus, improve patient management.

Background: Ophthalmic pathologies may further complicate the sensory input of patients with congenital hearing loss; however, data on children with coexisting impairment of vision and hearing is outdated, from before universal implementation of hearing screening programs.
Objectives: To examine the different ophthalmic pathologies among children with congenital sensorineural hearing loss (SNHL) before or after the introduction of a universal newborn hearing screening program (UNHSP).
Methods: Retrospective cohort study was conducted of 91 children diagnosed with congenital SNHL between 2005 and 2016 in a tertiary pediatric hospital. All patients completed an ophthalmologic examination, including assessment of visual acuity, refraction, ocular motility, slit lamp examination, and indirect funduscopy. Radiological assessment and genetic analysis were offered to all caregivers.
Results: Average age at diagnosis was 4.1 years. Nineteen children (21%) were diagnosed with an ophthalmic condition, of which the most common were refractive pathologies. Diagnosis of an ophthalmic pathology was twice as likely in the pre-UNHSP era (14 children, 27%) compared to the post-UNHSP era (5 children, 13%). Out of 91 children, 57 (63%) underwent a computed tomography scan and/or magnetic resonance imaging. Imaging was positive for structural abnormalities in 23 children (40%). There was no correlation between imaging and ophthalmic conditions. Genetic analysis was performed in 67 patients (74%).
Conclusions: The ophthalmic assessment of babies and children with congenital SNHL may yield in significant numbers of children with concomitant ophthalmic pathologies. Implementation of a UNHSP allows early diagnosis and treatment of coexisting ophthalmic and hearing conditions.

Background: Young women concerned about a breast cancer diagnosis will visit breast care centers and request breast cancer screening, including imaging studies, on their initial visit.
Objectives: To explore the role of breast examination and breast ultrasound in self-referred asymptomatic women under the age of 40 years.
Methods: We identified 3524 women under the age of 40 at our medical clinic from 1 January 2010 until 1 June 2014. Of this group, 164 women with above average breast cancer risk were excluded and 233 were excluded because of breast complaints. Of 3127 women, 220 underwent breast ultrasound following the initial visit to the clinic and formed the study group.
Results: Of 220 women evaluated with ultrasound, 68 had prior positive clinical findings. Of this group 8 women had no sonographic findings, and in the remaining 60, a total of 30 simple cysts, 15 fibroadenomas, and 15 suspicious solid masses were identified. One infiltrating ductal carcinoma and one ductal carcinoma in situ were found in a biopsy. The remaining 152 of the 220 total women who underwent breast ultrasound without showing prior physical findings did not require follow-up.
Conclusions: In the absence of clinical findings during physical breast examination, the addition of breast ultrasonography does not provide additional information to supplement the physical examination in self-referred women under age 40 who do not have any major risk factors for developing breast cancer.
