Background: Acute, as opposed to chronic, anterior uveitis is rarely associated with macular or optic nerve  edema. Nevertheless, mild changes may not be visible on examination.

Objectives: To implement non-invasive ocular coherence tomography (OCT) for obtaining quantitative and qualitative data in the assessment of changes in macular morphology and peripapillary retinal nerve fiber layers in eyes with acute anterior uveitis.

Methods: This retrospective case-control study was conducted in patients with unilateral acute anterior uveitis lasting for up to one month. Patients with evidence of other ocular disease or who had undergone intraocular surgery were excluded. We reviewed the charts of 14 consecutive patients who were diagnosed with acute unilateral anterior uveitis between 2007 and 2008 at the Tel Aviv Medical Center. Data on demographic details, ophthalmic examination, macular thickness and peripapillary retinal nerve fiber layer (RNFL) thickness (as demonstrated by OCT) were retrieved. Retinal and RNFL thickness was compared between the healthy fellow eye (control) and the uveitic eye in the central and four perifoveal quadrant regions, and RNFL thickness was compared in the mean and four quadrant values by Student’s t-test.

Results: We evaluated 28 eyes of 7 males and 7 females (mean age 37.7 years, range 20–65). The diagnoses were: idiopathic in five patients, ankylosing spondylitis in five, Crohn’s disease in one patient and reactive arthritis in one. Nine patients were HLA-B27 positive. The retina and the peripapillary NFL in each area were thicker in the uveitic eyes compared to the controls. The difference was statistically significant. There was no correlation between the differences in OCT values and patients’ demographic characteristics.

Conclusions: OCT demonstrated that eyes with acute anterior uveitis had thicker maculae and thicker peripapillary RNFL than controls. This finding suggests that even milder anterior uveitis may be associated with some degree of posterior segment manifestations.

Background: Since clinical signs of meningeal irritation in infants may be absent or misleading, the American Academy of Pediatrics in 1996 recommended that a lumbar puncture be performed in young children following a febrile seizure. Recent evidence supports a conservative approach in children who do not look ill at the time of the physician's assessment. Moreover, seizures as the presenting or sole symptom of bacterial meningitis are very rare.

Objectives: To assess physicians’ compliance with the Academy’s recommendations and to determine the incidence of meningitis among febrile seizure patients, including those who did not undergo the puncture.

Methods: We conducted a retrospective analysis of the number of punctures obtained in febrile seizure patients aged 6–24 months, focusing on the clinician's indications for performing the procedure and on the clinical course of children who did not undergo the puncture.

Results: Among 278 patients (84% simple febrile seizure), 52 (18.7%) underwent the procedure. It was performed in 38% of 45 complex febrile seizure cases and in 48% of 91 infants younger than 12 months of age. Aseptic meningitis occurred in two infants, both with post-ictal apathy. Bacterial meningitis was not found and in none of the patients who did not undergo the puncture was meningitis later diagnosed.

Conclusions: Compliance with the Academy’s recommendations was low, as emergency room physicians based their decision whether to obtain a lumbar puncture solely on clinical grounds. No case of bacterial meningitis was detected among 278 young children with a febrile seizure, including those who did not undergo the puncture.
 

Background: Fatigue is a common complaint in primary care and has a broad differential diagnosis, making the approach complex and often ineffective.

Objectives: To follow the course of adults without a significant known background disease who complain of fatigue for the first time, and to characterize the family physician’s approach.

Methods: The study population comprised a random sample of 299 patients aged 18–45 who presented with fatigue as a first-time single complaint to their family physician. Excluded were patients with chronic diseases or states that may include signs of fatigue. We analyzed the index encounter data, the diagnostic and laboratory tests, the medications prescribed and the one year clinical outcome.

Results: Seventy percent were women, average age 30.5 years, and 69% had no known co-morbidities; 57% of the patients were physically examined at the first visit and most (78.6%) were sent for laboratory analysis. Five percent of laboratory tests were positive. Eighty patients (26.8%) were given a specific diagnosis, with the leading diagnoses being anemia and infectious diseases; 18.7% were given sick leave at the first visit. Fatigue was more common in early summer.

Conclusions: The majority of young healthy patients complaining of fatigue are not diagnosed with an organic physiological disorder. Many of the study patients were sent for laboratory tests but in most cases these tests were not contributory to the diagnosis or management. It seems likely that the most efficient strategy would be watchful follow-up with a minimum of testing.

Background: Human brucellosis is common in southern Israel among the semi-nomadic Bedouin, a population that consumes unpasteurized dairy products. Though camel milk ingestion is a known mechanism for brucellosis acquisition, only a few reports of sporadic cases have been published in the medical literature.

Objectives: To describe a local brucellosis outbreak in 15 extended Bedouin family members, following ingestion of infected camel milk.

Methods: Data regarding patient’s clinical manifestations, laboratory findings, treatment and outcome were collected from the hospital and the health fund clinics’ computerized database. Camel’s blood and milk were tested for Brucella serology and culture. Cases were defined by positive Rose Bengal test, symptoms correlating with brucellosis, and consumption of infected camel milk.

Results: Fifteen patients were diagnosed with acute brucellosis from March to June 2011. Sixty percent of cases had serum agglutination test titers of 1:160 or higher and 4/8 (50%) had positive blood culture for Brucella melitensis. Arthralgia and fever were the most consistent clinical manifestations. Blood and milk serology and milk culture taken from the female camel were positive for Brucella melitensis.

Conclusions: The treating physicians must consider the possibility of infected camel milk ingestion as the mode of infection, both in sporadic cases and in outbreaks of brucellosis.

Background: Defibrillation threshold (DFT) testing at the time of implantable cardioverter defibrillator (ICD) insertion is performed routinely. Recently this practice is being reconsidered due to doubts about its ability to improve ICD efficacy and evidence that survival may not be affected by the test.

Objectives: To compare the outcome of ICD recipients who underwent DFT testing and those in whom no testing was performed.

Methods: A total of 213 eligible patients were implanted with an ICD between 2004 and 2009. DFT testing was performed in 80. We compared total mortality, appropriate and inappropriate ICD shocks, and anti-tachycardia pacing (ATP) events between DFT and non-DFT patients during a follow-up of 2 years.

Results: On comparing the DFT and non-DFT groups, we found a 2 year mortality rate of 7.5% versus 8.3%, respectively (P = 0.8). Furthermore, 20.7% of patients in the DFT group and 12.4% in the non-DFT group had at least one episode of ICD shock (P = 0.15). With regard to ICD treatment (ICD shocks or ATP events), 57.7% in the DFT group and 64.2% in the non-DFT group received appropriate treatments (P = 0.78).

Conclusions: No significant differences in the incidence of 2 year mortality or percentage of ICD treatment emerged between the DFT and non-DFT groups.
 

Background: Clefts of the lip and palate are the most common significant congenital birth anomaly of orofacial region. The condition may vary from a minor easily correctable cleft to a significant functional and cosmetic incapacitation. This is the first epidemiological study of orofacial clefts in the Negev region in Israel.

Objectives: To establish the frequency of cleft lip and palate in the population of the Negev, characterize the demographic features of affected individuals and find possible risk factors, compare the risk in two major population groups: Bedouin and Jewish in a well-defined geographic area, and determine whether there is a change over time in the birth of babies with facial clefts.

Methods: We conducted a retrospective survey of the Soroka Medical Center archives. The sample population comprised all 131,218 babies born at Soroka during the 11 year period 1 January 1996 to 31 December 2006. Statistical tests used Pearson's chi-square test, Student’s t-test and Spearman's correlation coefficient test according to the type of parameter tested.

Results: During the study period 140 babies were born with orofacial cleft. The overall incidence of cleft lip and palate was 1.067/1000. The incidence of facial clefts was 1.54/1000 among Bedouins and 0.48/1000 among Jews (P < 0.001). Cleft palate was significantly more frequent in female than male babies (P = 0.002). Over the study years we found a significant decrease in the incidence of facial clefts in the Bedouin population, with Spearman's correlation coefficient rank -0.9 (P < 0.01).

Conclusions: A significant decrease occurred in the incidence of facial clefts among Bedouin. This change may be attributed to prenatal care in the Bedouin Negev population as part of social and health-related behavior changes. The reduction in rates of congenital malformations, however, does not mean a reduction in the number of cases in a growing population. Also, with a modern western lifestyle, the expectancy and demand for reconstructive facial surgery and comprehensive care for these children are on the rise.
