Almost three-quarters of a century ago an American surgeon named Frederick Edward Mohs, had the idea of excising skin cancers and examining the margins before the closure of the surgical wound. In this manner he thought the patient would get better treatment with the best cosmetic result.

Mohs micrographic surgery (MMS) in its present format has been used as a surgical method for treating skin cancers for the last 70 years. The method became popular with American dermatologists 54 years ago when the original Mohs technique was modified into its fresh tissue modality [2] and in the rest of the Western world and Israel more than 35 years ago. Variations of MMS started to appear and indications for surgery also expanded. At the beginning, MMS was indicated mainly for basal and squamous cell carcinomas–nonmelanoma skin cancers (NMSC). Knowledge has been collected and today the method is applicable for a variety of other skin cancers such as melanoma in situ, microcystic adnexal carcinoma, dermatofibrosarcoma protuberans (DFSP), and other adnexal and spindle cell tumors. In this issue of the Israel Medical Association Journal (IMAJ), Landov and colleagues [3] showed the value of MMS for the treatment of DFSP.

Background: The recreational use of nitrous oxide (N₂O) has increased in recent years with a noticeable surge in the incidence of nitrous oxide-related myeloneuropathy.

Objectives: To raise awareness of increasing myeloneuropathy due to recreational nitrous oxide misuse in Israel.

Methods: We conducted a case series documenting the clinical and investigative features of eight patients presenting with nitrous oxide-induced myeloneuropathy who were admitted to our departments.

Results: Paresthesia was the chief complaint in all patients, with sensory gait ataxia being a common feature, which was often accompanied by Romberg's sign and mild lower limb weakness. Vitamin B12 levels were below the normal range in seven patients, accompanied by elevated homocysteine and methylmalonic acid levels. Magnetic resonance imaging scans revealed hyperintense signals in the dorsal columns of the cervical spine. All patients improved following vitamin B12 injections.

Conclusions: Enhancing awareness, prompting the use of appropriate investigations, and advocating for timely treatment are needed to overcome the risks associated with nitrous oxide misuse.

Illicit drug abuse is a widespread medical problem with numerous sequelae. One of the major challenges in reaching a diagnosis is the difficulty in obtaining accurate details during the medical interview. We describe a patient who initially denied drug abuse while presenting a bizarre nasopharyngeal disease secondary to inhalation of oxycodone-acetaminophen powder.

Background: A history of childhood sexual abuse (CSA) has been linked to a variety of physical and psychiatric illnesses, including ischemic heart disease and post-traumatic stress disorder (PTSD).

Objectives: To determine the prevalence of past CSA and re-traumatization among hospital psychiatric consultations and to determine whether a CSA group in a hospital setting shared characteristics with community samples described in the literature.

Methods: We divided 228 consecutive psychiatric consultations into two groups. One group comprised patients with a past history of CSA while the other group had no such history. Both groups were further divided into a subgroup that presented with features of re-traumatization.

Results: In the cohort, 38% described a history of CSA. Twenty patients were identified as presenting with features of re-traumatization. There were significant differences between the two groups. The patients with a history of CSA were more likely to have arrived at the emergency department (ED) during the preceding 12 months with a diagnosis of PTSD, personality disorder, and substance use disorder. There was a greater proportion of patients in the CSA group who had grown up in an ultra-Orthodox Jewish household and who currently identified as being secular.

Conclusions: The characteristics of the patients with past CSA in this study are similar to community-based samples, except for a significant gender difference. To the best of our knowledge, this study is the first to investigate CSA history during hospital ED psychiatric consultations. A history of CSA should be considered during psychiatric consultations in a general hospital ED admission.

Background: Some specialists and policy makers advocate progression of the mental health reform in Israel by transferring beds from psychiatric to general hospitals.

Objectives: To compare the demographic, diagnostic and psychopathological profiles of psychiatric inpatients hospitalized in psychiatric and general hospitals, as well as their patterns of drug abuse and to estimate the preparedness of general hospitals for the possible expansion of their psychiatric services.

Methods: Between 2002 and 2006 a total of 250 patients were consecutively admitted to the Jerusalem Mental Health Center-Kfar Shaul Hospital and 220 to the psychiatric department of Sheba Medical Center, a general hospital in central Israel; the patients’ ages ranged from 18 to 65. The two groups were compared for demographic features, psychiatric diagnoses and severity of psychopathology (utilizing PANSS, HAD-21, YMRS rating scales). Drug abuse was diagnosed by urine analyses and self-report.

Results: The patients in the psychiatric hospital were significantly younger, predominantly male, and more dependent on social security payments. In the general hospital, diagnoses of affective and anxiety disorders prevailed, while in the psychiatric hospital schizophrenic and other psychotic patients constituted the majority. The patients in the general hospital were decidedly more depressed; in the psychiatric hospital, notably higher rates of manic symptoms as well as positive, negative and general schizophrenic symptoms were reported. For the most abused substances (opiates, cannabis and methamphetamines) the rates in the psychiatric hospital were significantly higher.

Conclusions: The differences between the two groups of inpatients were very pronounced, and therefore, the transferring of psychiatric beds to general hospitals could not be done without serious and profound organizational, educational and financial changes in the psychiatric services of general hospitals. Since each of the two inpatient systems has particular specializations and experience with the different subgroups of patients, they could coexist for a long time.
 

Background: For health professionals who interact professionally with children, adequate awareness and training regarding the clinical indicators of child abuse and neglect, as well as subsequent reporting and procedures, are essential.

Objectives: To study Israeli health professionals’ experiences with identification and reporting of suspected cases of child abuse and neglect, and their perceived training needs in this area.

Methods: The study group was a convenience sample comprising 95 Israeli health professionals (physicians, nurses, social workers, psychologists, etc.) attending workshops on medical aspects at a national conference on child abuse and neglect. The study was a cross-sectional survey. The health professionals were asked to complete an anonymous structured questionnaire on their experience with child abuse and neglect and on their training needs.

Results: The participants in the survey had relatively high levels of involvement with child protection. Nevertheless, they strongly expressed their need for training, especially in mastering practice skills. The need for training was greater for professionals with less experience in child protection, and there were different needs according to profession.

Conclusions: Despite their prior extensive experience in dealing with child abuse and neglect, most of the health professionals participating in the conference reported the need for training in various areas.

Background: Clinicians’ impression of adolescents' alcohol or drug involvement may underestimate substance-related pathology.

Objectives: To describe the characteristics of adolescents presenting to the pediatric emergency department due to substance abuse and to determine whether physicians can reliably identify these patients.

Methods: We conducted a prospective cohort study of all patients aged 12–18 years presenting to a pediatric emergency department between 1 January 2005 and 31 December 2006 for whom a urine drug screen or ethanol blood levels was ordered. According to departmental protocol urine drug screen and ethanol levels are taken for specific indications. Based on the history and clinical findings the pediatrician in the ED[1] assessed on a 5-point likelihood scale the possibility that the patients’ symptoms were related to substance abuse.

Results: Of the 139 patients in the study group 40 (30%) tested positive for ethanol or drugs of abuse. The median age was 16. Compared with patients who tested negative, there were more patients with decreased level of consciousness among patients who tested positive for ethanol or drugs (5% vs. 33% respectively, P < 0.001). The median physician estimate for the likelihood of substance abuse was 5 in patients who tested positive and 2 in patients who tested negative (P < 0.001). The likelihood of a positive drug/ethanol test was not affected by age or gender.
Conclusions: Since the likelihood of substance abuse is higher in patients presenting with a low level of consciousness, physicians may accurately assess the likelihood of substance abuse in these patients

Background: In recent years, mother to child transmission of human immunodeficiency virus in the west has decreased markedly due to the advent of antiretroviral drugs given during pregnancy, cessation of lactation and careful monitoring of viral load in the perinatal period.

Objective: To assess mother to child transmission of HIV[1] among Ethiopian immigrants and non-Ethiopians in the Jerusalem area.

Methods: We conducted a prospective analysis of all deliveries of HIV-positive women in the Jerusalem district over a 10 year period.

Results: Between 1996 and 2006, 35 HIV⁺ women gave birth to 45 infants. Thirty-one (88%) of these women were of Ethiopian origin and gave birth to 39 infants. Of the 35 HIV⁺ women, 30 were aware of being HIV positive. They gave birth to 40 infants. Another 5 women (14%) were not aware of being HIV⁺ during delivery. They gave birth to five infants. Of the group of known HIV⁺ women, 26 (87%) were Ethiopian immigrants who delivered 34 infants and 4 were non-Ethiopians who delivered 6 infants. In the group of five women not aware of being HIV⁺, all were Ethiopians. Breast-feeding data were available for 32 of the 35 women. Only 2 women (6.2%) breast-fed their babies. Neither was aware of being HIV⁺. In the Ethiopian immigrant group (both known and unknown HIV status), 11 deliveries (28%) were vaginal, 18 (46%) were elective cesarean section and 10 (26%) were delivered by emergency cesarean section. Of the 26 known HIV⁺ Ethiopian women, 3 (12%) refused to take antiretroviral treatment despite repeated counseling. In the non-Ethiopian group, all deliveries were elective cesarean sections. Mother to child transmission of HIV occurred in 4 of the total 45 deliveries (8.8%). Of the 4 transmission cases, 2 occurred among 40 deliveries of known HIV⁺ women (5%), and 2 occurred among the 5 deliveries of women not aware of being HIV⁺ (40%, P = 0.05). In the group of Ethiopian women only, HIV transmission occurred in 4 of 39 deliveries (10%), of which 2 occurred among 34 deliveries (5.8%) of women know to be HIV⁺ and 2 among 5 deliveries (40%) of women not aware of being HIV⁺ (P = 0.08).

Conclusions: Pregnant Ethiopian immigrants whose HIV status was known during pregnancy were at relatively high risk of HIV transmission despite the availability of antiretroviral drugs and counseling. This is likely due to inadequate adherence to ART[2] preventive regimens and is not dissimilar to the poor adherence observed among other immigrant groups in western countries. The substantial proportion of women, all Ethiopians, unaware of being HIV⁺ at delivery, together with the significantly higher HIV transmission in that group compared to women who knew their HIV status, call for a revision of the current Ministry of Health opt-in policy for prenatal HIV screening.

Background: The co-morbidity rate of illicit substance abuse and major mental problems in Israel is far from clear.

Objectives: To investigate the extent of drug abuse in a sample of psychiatric patients hospitalized in a psychiatric hospital and in the psychiatric department of a general hospital in Israel, to compare demographic and other background factors in dual-diagnosis patients with those of abuse-free mental inpatients, and to examine the time correlation between drug abuse and the appearance of major mental problems.

Methods: Our data were derived from self-report and urine tests. The study population comprised 470 consecutively admitted patients – 250 patients in the mental health center and 220 patients in the psychiatric department of the general hospital.

Results: The lifetime prevalence of drug abuse was 24%; cannabis abuse was found in 19.7%, opiates in 5.7%, cocaine in 2.7%, amphetamines in 3.4% and methamphetamine in 1.1%. Active abuse of drugs (during the last month) was registered in 17.3%, cannabis in 11.5%, opiates in 4.9%, amphetamine in 3.8%, cocaine in 1.3% and methamphetamine in 1.1%. We also found that 28.2% of active abusers used two or more substances. In 41.6% the drug abuse appeared prior to symptoms of the mental disorder; in 37.1% the duration of the mental disorders and the drug abuse was relatively similar, and in 21.3% of cases the duration of mental problems was longer than the duration of drug abuse. Dual-diagnosis patients were younger than non-abusers, more often male, unmarried, and of western origin.

Conclusions: Substance abuse (especially cannabis) among hospitalized psychiatric patients in Israel is a growing problem.

Background: The association between antibiotic use in the community and antimicrobial resistance is known. Attention has recently focused on the type of agents being prescribed.

Objectives: To implement, evaluate and compare the efficacy of two community interventions programs – continuous versus seasonal medical education – oriented to primary care physicians with emphasis on appropriate use of antimicrobial drugs.

Methods: From October 2000 to April 2003 we conducted two interventions: a) a monthly educational campaign in selected clinics promoting appropriate diagnosis of common infectious diseases and prudent antibiotic use (continuous intervention group); and b) a massive educational campaign, conducted before two consecutive winters, promoting the judicious use of antibiotics for treating respiratory infections (continuous intervention group and seasonal intervention group). Sixteen similar clinics were randomized (8 to each group). The total antibiotic use was measured as defined daily dose/1000 patients/day, and compared between the groups. 

Results: The total use of antibiotics decreased between 1999-2000 and 2002-2003 in both groups, but slightly more significantly in the continuous intervention group. The DDD/1000 patients/day for the seasonal group in 1999-2000 was 27.8 vs. 23.2 in 2002-2003; and for the continuous group 28.7 in 1999-2000 vs. 22.9 in 2002-2003, a reduction of 16.5% and 20.0% respectively (p<0.0001). The main change in antibiotic use was noted for broad-spectrum antibiotics.

Conclusions: We present a successful community intervention program aimed to reduce unnecessary antibiotic use. Amplification of this type of intervention is imperative to stop the increase in antimicrobial resistance.
