Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease involving apocrine gland-bearing regions. There is an under-representation of non-Caucasians in epidemiologic studies of HS. The characteristics of HS in Israeli Arabs have not yet been studied. OBJECTIVES To investigate the demographic and clinical profile of HS in the Israeli Arab population. METHODS A retrospective analysis was conducted in two cohorts of patients with HS in Israel. The patients were derived from the database of a large health management organization (n=4191, 639 Arabs; population-based) and a major tertiary medical center (n=372, 49 Arabs). Demographic and clinical data were compared between ethnic groups. RESULTS The prevalence of HS in Israeli Arabs was found to be 0.5%, fivefold higher than in Jews. Arab patients were younger (35.3 vs. 40.5 years, P < 0.001) and mostly male (52% vs. 35.7%, P < 0.001), with lower rates of co-morbidities, including smoking (40.8% vs. 55.7%, P < 0.001), hyperlipidemia, and depression as well as a higher rate of dissecting cellulitis (10.2% vs. 1.9%, P = 0.008). HS was more severe in Arabs, but of shorter duration, with mainly axillary involvement (79.6% vs. 57.9%, P = 0.004). Treatment with hormones was more common in Jews, and with biologic agents in Arabs. CONCLUSIONS The findings suggest a different phenotype of HS in Arabs, warranting further study.

Association between Hidradenitis Suppurativa and Abnormalities in Semen Parameters and Sexual Function: A Pilot Study. Acta Derm Venereol 2023; 103:adv11603. [PMID: 37974484 PMCID: PMC10666065 DOI: 10.2340/actadv.v103.11603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 10/10/2023] [Indexed: 11/19/2023] Open
Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease affecting patients of reproductive age. Although HS shares risk factors with male infertility, only 1 epidemiological study has evaluated this association. To further evaluate this potential association, findings on semen and hormonal analysis, testicular ultrasound, and the International Index of Erectile Function (IIEF-15) were compared between 28 men attending a tertiary HS clinic during the period April 2019 to April 2021, and 44 healthy controls, spouses of infertile women undergoing semen evaluation before in vitro fertilization. Patients with HS were divided based on the absence or presence of gluteal and genital lesions. Patients with HS were younger than controls (median 27 vs 34 years, p < 0.0004) and had a higher proportion of smokers (86% vs 33%, p < 0.0001). Semen parameters in patients with gluteal-genital lesions, specifically those with severe scrotal involvement necessitating surgery, were lower than the WHO reference values and significantly lower than in patients without gluteal-genital lesions and controls. Erectile dysfunction was reported by 93% of patients with HS. These findings suggest that spermatogenesis and sexual function may be impaired in young men with HS. Therefore, multidisciplinary management of HS should include their evaluation to identify patients who might benefit from semen cryopreservation and sexual treatment.

Occupational exposure and risk of oral and oropharyngeal squamous cell carcinoma: systematic review and 25-year retrospective cohort study of patients. Br J Oral Maxillofac Surg 2023; 61:39-48. [PMID: 36443129 DOI: 10.1016/j.bjoms.2022.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 10/23/2022] [Accepted: 11/01/2022] [Indexed: 11/06/2022]
Abstract
Social habits such as smoking and drinking alcohol are well-known causative agents for oral and oropharyngeal squamous cell carcinoma (OSCC/OPSCC). Human papillomavirus (HPV) is a known causative agent for OPSCC. However, we often encounter patients with no identifiable risk factors. There is growing evidence of the role of occupational carcinogens in the pathogenesis of oral cancer. The aim of this study therefore was to identify any occupational carcinogens linked to oral cancer. We carried out a systematic review of the literature using PubMed, EMBASE, and Medline, along with a retrospective review of patients treated in a regional unit over 25 years. Occupations were classified based on the UK Standard of Classification 2020. Data analysis was completed using the chi-squared test. A total of 17 papers met the inclusion criteria for review. In our retrospective study a total of 874 patients were identified of whom 31% were blue-collar workers, 32.8% were white-collar workers, 20.2% were unemployed/housewives, and 16% workers in other occupations. The majority of blue-collar workers were in the construction industry and had maximum exposure to hydrocarbons and exhaust fumes. The aetiology of oral and oropharyngeal SCC is multifactorial and there is no consensus on the role of occupational carcinogens. We showcase our patient cohort and discuss the occupational exposures that appear to make them susceptible to OSCC and OPSCC. Further multicentre studies are required to enable us to understand fully the pathogenesis of oral cancer and help us to inform relevant organisations, the aim being to reduce the incidence of occupation-related cancer.

New Insights into Macular Type of Primary Cutaneous B-Cell Lymphoma: Extension of the Clinical and Histopathological Patterns. Dermatology 2022; 238:1018-1025. [PMID: 35817021 DOI: 10.1159/000525439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Accepted: 04/24/2022] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Primary cutaneous B-cell lymphoma (PCBCL) classically presents with papules, plaques, and nodules/tumors. Previous reports of PCBCL manifesting with macular lesions are scarce and focused on primary cutaneous follicle-center cell lymphoma (PCFCL). OBJECTIVES The objective of this study was to report our experience with PCBCL presenting with erythematous macules. METHODS Patients with low-grade PCBCL manifesting with erythematous patches, diagnosed and managed between January 2000 through December 2019 at 2 tertiary cutaneous-lymphoma outpatient clinics, were included. Clinical data were retrospectively collected, and biopsy specimens of the macules, and if present of the typical nodular/tumoral lesions, were reviewed. RESULTS There were 14 patients, aged 16-67 years, 8 had PCFCL and 6 marginal zone lymphoma (PCMZL). All had 1-15 cm erythematous macules, mimicking: interstitial granuloma annulare/vascular tumors/early-stage folliculotropic mycosis fungoides, or presenting with figurate erythema or livedo reticularis-like/net-like pattern. In 3 patients, macules were the presenting lesions, in 2 as the sole manifestation, whereas in 12 patients, typical PCBCL lesions were observed during disease course. The macules showed in all, superficial and deep perivascular infiltrates, and in most, periadnexal infiltrates. Micronodules were observed in 11 specimens, with nodular infiltrates also observed in 4. B cells comprised the majority of the lymphocytes in only 4. Seven of 11 cases tested showed immunoglobulin heavy chain monoclonality. CONCLUSIONS PCMZL and PCFCL may manifest with erythematous macules. Physicians should be aware of this unusual manifestation of low-grade PCBCL, which may represent a clinicopathological diagnostic pitfall.

The Bacteriology of Skin Lesions in Patients with Hidradenitis Suppurativa Is Associated with Previous Antibiotic Treatment in the Community Setting: A Referral Center Experience. Dermatology 2022; 238:772-784. [PMID: 35086093 DOI: 10.1159/000520288] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Accepted: 10/18/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic skin disease characterized by inflammatory nodules and abscesses. The pathogenic role of bacteria is not fully understood. As the diagnosis is usually delayed, patients are often treated with several lines of antibiotics in a nonstandardized fashion. The aim of the study was to investigate and compare the bacteriology of active HS lesions in patients treated or not treated with antibiotics in the community setting before referral to a dedicated HS clinic. METHODS Purulent skin lesions of patients with HS referred to the HS Clinic of Rabin Medical Center in 2009-2020 were cultured. Data were collected from the patients' medical files and microbiology reports. The correlation between the location of the skin lesion and the bacteriologic profile was analyzed, and the effects of previous antibiotic treatment on the bacteriologic profile of the lesions and susceptibility patterns of the cultured bacteria were evaluated. RESULTS Pus (or tissue) from inflammatory lesions of 97 patients with HS was cultured. Mean (SD) patient age was 39.5 (13.0) years, and mean delay in diagnosis was 7.3 (8.3) years. Most patients (57.7%) had dominant involvement of one location, with the most active lesions concentrated in the genitalia, gluteal/perineal area, and axilla. Enterobacterales species were the most frequent isolates detected in all locations except the face and scalp. Seventy-eight patients (80.4%) had been treated in the community setting prior to referral with a median (range) of 2 (1-8) lines of antibiotics. The most commonly prescribed antibiotics were amoxicillin/clavulanate (22.0%), doxycycline/minocycline (16.8%), clindamycin (16.2%; monotherapy 8.1%, clindamycin with rifampicin 8.1%), and cephalexin (13.9%). Compared to the previously untreated patients, cultures of lesions from the previously treated patients yielded a higher percentage of gram-negative Enterobacterales (the most common isolates in this group) (31.3% vs. 10.3%) and a significantly higher median number of isolates per culture (2 vs. 1, p < 0.0001). Gram-positive bacteria, usually considered contaminants (mainly coagulase-negative staphylococci) accounted for 31.0% of the isolates in the previously treated group. Susceptibility testing for the entire cohort revealed 100% bacterial sensitivity to ciprofloxacin. Staphylococcus spp. were 100% sensitive to rifampicin. Both gram-positive and gram-negative bacteria had high sensitivity to trimethoprim and sulfamethoxazole. CONCLUSION Nonstandardized antibiotic treatment of HS in the community setting can skew the microbiology of skin lesions toward gram-negative bacteria. Therefore, treatment with trimethoprim and sulfamethoxazole or ciprofloxacin, either alone or combined with rifampicin, may be considered.

Abstract
Kikuchi-Fujimoto is a rare but self-limiting disease usually affecting young ethnic females. The main clinical presentation is fever and cervical lymphadenopathy. Here we describe the cases of two patients with cervical lymphadenopathy, fever and fatigue. In addition, patients can present with neutropenia; hence, early diagnosis is crucial to exclude a malignant cause.

Abstract
An area critical to safety in an organisation is the perceived and actual culture. National Air Traffic Services (NATS) work closely with large safety-critical industries including various aviation companies to enable them to identify strengths and vulnerabilities with the aim of improving safe practice. NATS have developed a simple free downloadable self-assessment App that individuals can use to assess their own culture perception in their organisation. The App has 16 questions arranged in four domains but to our knowledge it has not been used to date in healthcare. As part of the initiatives to improve staff culture, we evaluated operating theatre colleagues' safety perception in our large acute NHS Trust in a pilot study using the NATS safety App. Staff downloaded the App to their smart device before completing it. Responses were sent anonymously through the App and collated by NATS. A total of 146 colleagues downloaded and completed the questionnaire. One hundred and seventeen staff (80%) felt encouraged to report safety concerns, but 86% (n=126) confirmed a lack of available support from healthcare managers. Only 43% of respondents (n=63) would find it easy to challenge colleagues if they observed unsafe behaviour. This pilot study has identified positive indicators of an evolving NHS safety culture, and some concerns about speaking up, support, and challenging colleagues without fear. These issues are known to occur across healthcare. Further work is needed in the NHS to provide a supportive environment to improve patient safety, and lower hierarchy in surgical teams.

Abstract
Patients with mycosis fungoides (MF) are thought to be at increased risk of melanoma. However, studies addressing surveillance-bias and treatments as a possible confounder are lacking. This retrospective study compared the prevalence and risk of melanoma between 982 patients with MF, and 3,165 patients with psoriasis attending tertiary cutaneous-lymphoma/psoriasis clinics during 2009 to 2018. Melanoma was diagnosed in 47 patients with MF (4.8%; 43 early stage) and in 23 patients with psoriasis (0.7%) (odds ratio 6.6, p < 0.0001). In 60% of patients, MF/psoriasis preceded melanoma diagnosis. Hazard ratio (HR) for a subsequent melanoma in MF vs psoriasis was 6.3 (95% confidence interval (95% CI) 3.4–11.7, p < 0.0001). Compared with the general population, melanoma standardized incidence ratios were 17.5 in patients with MF (95% CI 11.0–23.9, p < 0.0001), and 2.2 (95% CI 0.6–3.8, p = 0.148) in patients with psoriasis. Narrow-band ultraviolet B was not a contributory factor (HR 1.15, 95% CI 0.62–2.14, p = 0.66). These findings add evidence that patients with MF have a significantly higher risk of melanoma, not only compared with the general population, but also compared with patients with psoriasis. This comorbidity may be inherent to MF.

Abstract
Data on the treatment of early folliculotropic mycosis fungoides, a recently defined clinicopathological subgroup of folliculotropic mycosis fungoides with an indolent course, is limited. Treatment outcomes were studied in a retrospective cohort of 47 adults with early folliculotropic mycosis fungoides, with a focus on psoralen plus ultraviolet A (PUVA) monotherapy, including dosimetric data, and the findings were compared with data for PUVA in 18 adults with early-classic mycosis fungoides. PUVA was given to 27 patients with early folliculotropic mycosis fungoides: 70% achieved complete response and 26% partial response. Significantly more treatments were needed to achieve complete response in stage IB compared with stage IA. There was no significant difference in the complete response rate from classic plaque-stage disease, although the early folliculotropic mycosis fungoides group required more treatments to achieve complete response, and a higher cumulative dose of UVA. Thus, PUVA is an effective treatment for early folliculotropic mycosis fungoides. Its complete response rate might be equal to early-classic mycosis fungoides; however, a longer induction phase is needed to achieve complete response.

Abstract
BACKGROUND Erysipelas and cellulitis (hereafter referred to as 'cellulitis') are common bacterial skin infections usually affecting the lower extremities. Despite their burden of morbidity, the evidence for different prevention strategies is unclear. OBJECTIVES To assess the beneficial and adverse effects of antibiotic prophylaxis or other prophylactic interventions for the prevention of recurrent episodes of cellulitis in adults aged over 16. SEARCH METHODS We searched the following databases up to June 2016: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and LILACS. We also searched five trials registry databases, and checked reference lists of included studies and reviews for further references to relevant randomised controlled trials (RCTs). We searched two sets of dermatology conference proceedings, and BIOSIS Previews. SELECTION CRITERIA Randomised controlled trials evaluating any therapy for the prevention of recurrent cellulitis. DATA COLLECTION AND ANALYSIS Two authors independently carried out study selection, data extraction, assessment of risks of bias, and analyses. Our primary prespecified outcome was recurrence of cellulitis when on treatment and after treatment. Our secondary outcomes included incidence rate, time to next episode, hospitalisation, quality of life, development of resistance to antibiotics, adverse reactions and mortality. MAIN RESULTS We included six trials, with a total of 573 evaluable participants, who were aged on average between 50 and 70. There were few previous episodes of cellulitis in those recruited to the trials, ranging between one and four episodes per study.Five of the six included trials assessed prevention with antibiotics in participants with cellulitis of the legs, and one assessed selenium in participants with cellulitis of the arms. Among the studies assessing antibiotics, one study evaluated oral erythromycin (n = 32) and four studies assessed penicillin (n = 481). Treatment duration varied from six to 18 months, and two studies continued to follow up participants after discontinuation of prophylaxis, with a follow-up period of up to one and a half to two years. Four studies were single-centre, and two were multicentre; they were conducted in five countries: the UK, Sweden, Tunisia, Israel, and Austria.Based on five trials, antibiotic prophylaxis (at the end of the treatment phase ('on prophylaxis')) decreased the risk of cellulitis recurrence by 69%, compared to no treatment or placebo (risk ratio (RR) 0.31, 95% confidence interval (CI) 0.13 to 0.72; n = 513; P = 0.007), number needed to treat for an additional beneficial outcome (NNTB) six, (95% CI 5 to 15), and we rated the certainty of evidence for this outcome as moderate.Under prophylactic treatment and compared to no treatment or placebo, antibiotic prophylaxis reduced the incidence rate of cellulitis by 56% (RR 0.44, 95% CI 0.22 to 0.89; four studies; n = 473; P value = 0.02; moderate-certainty evidence) and significantly decreased the rate until the next episode of cellulitis (hazard ratio (HR) 0.51, 95% CI 0.34 to 0.78; three studies; n = 437; P = 0.002; moderate-certainty evidence).The protective effects of antibiotic did not last after prophylaxis had been stopped ('post-prophylaxis') for risk of cellulitis recurrence (RR 0.88, 95% CI 0.59 to 1.31; two studies; n = 287; P = 0.52), incidence rate of cellulitis (RR 0.94, 95% CI 0.65 to 1.36; two studies; n = 287; P = 0.74), and rate until next episode of cellulitis (HR 0.78, 95% CI 0.39 to 1.56; two studies; n = 287). Evidence was of low certainty.Effects are relevant mainly for people after at least two episodes of leg cellulitis occurring within a period up to three years.We found no significant differences in adverse effects or hospitalisation between antibiotic and no treatment or placebo; for adverse effects: RR 0.87, 95% CI 0.58 to 1.30; four studies; n = 469; P = 0.48; for hospitalisation: RR 0.77, 95% CI 0.37 to 1.57; three studies; n = 429; P = 0.47, with certainty of evidence rated low for these outcomes. The existing data did not allow us to fully explore its impact on length of hospital stay.The common adverse reactions were gastrointestinal symptoms, mainly nausea and diarrhoea; rash (severe cutaneous adverse reactions were not reported); and thrush. Three studies reported adverse effects that led to discontinuation of the assigned therapy. In one study (erythromycin), three participants reported abdominal pain and nausea, so their treatment was changed to penicillin. In another study, two participants treated with penicillin withdrew from treatment due to diarrhoea or nausea. In one study, around 10% of participants stopped treatment due to pain at the injection site (the active treatment group was given intramuscular injections of benzathine penicillin).None of the included studies assessed the development of antimicrobial resistance or quality-of-life measures.With regard to the risks of bias, two included studies were at low risk of bias and we judged three others as being at high risk of bias, mainly due to lack of blinding. AUTHORS' CONCLUSIONS In terms of recurrence, incidence, and time to next episode, antibiotic is probably an effective preventive treatment for recurrent cellulitis of the lower limbs in those under prophylactic treatment, compared with placebo or no treatment (moderate-certainty evidence). However, these preventive effects of antibiotics appear to diminish after they are discontinued (low-certainty evidence). Treatment with antibiotic does not trigger any serious adverse events, and those associated are minor, such as nausea and rash (low-certainty evidence). The evidence is limited to people with at least two past episodes of leg cellulitis within a time frame of up to three years, and none of the studies investigated other common interventions such as lymphoedema reduction methods or proper skin care. Larger, high-quality studies are warranted, including long-term follow-up and other prophylactic measures.

Abstract
BACKGROUND Recent data have shown an increasing occurrence of atopic dermatitis (AD) in children and adolescents, as well as in adults. Most of the epidemiologic research on AD is limited to pediatric and youth populations and is based on self-reported questionnaires. METHODS A nationwide, population-based, cross-sectional retrospective study of adolescents with AD was performed to estimate its prevalence, trends, and association with demographic factors and comorbidities. The study included all Israeli teens going through medical evaluation as part of the assessment before being conscripted into the military from 1998 to 2013. RESULTS A total of 1,187,757 adolescents were included in the study population, with an overall prevalence of AD of 0.64% in boys and 0.9% in girls. Over the study period, the prevalence of AD steadily increased, especially in the mild disease group. A greater risk of AD was found in subjects with high predicted socioeconomic status (male: odds ratio [OR] 1.14 [95% confidence interval {CI} 1.11, 1.16]; female: OR 1.08, [95% CI 1.05, 1.10]) and Israeli-born subjects (male: OR 1.34 [95% CI 1.21, 1.48]; female: OR 1.12 [95% CI 1.01, 1.23]). Allergic conditions such as asthma, conjunctivitis, and contact dermatitis were more prevalent in subjects with AD. There was a significantly higher prevalence of migraine in patients with AD (male: OR 1.35 [95% CI 1.18, 1.54]; female: OR 1.51 [95% CI 1.30, 1.74]). CONCLUSION This large cross-sectional study demonstrates the increasing prevalence of AD in adolescents and its relation to other allergic diseases and migraine. It is hoped that greater awareness of the distinctive epidemiologic characteristics of this population will lead to better recognition and management of the disease and its comorbidities.

Abstract
Bluetongue (BT) and peste-des-petits-ruminants (PPR) are major transboundary diseases of small ruminant, which are endemic in India. Testing of bluetongue virus (BTV) and peste-des-petits-ruminants virus (PPRV) from recent outbreaks (2015-2016) in different regions of Haryana State of India revealed that 27.5% of the samples showed the presence of dual infection of BTV and PPRV. Analysis of Seg-2 of BTV (the serotype-determining protein) showed the presence of BTV-12w in several isolates. However, analysis of N gene fragment amplicons showed that viruses belong to lineage IV were most closely related to a pathogenic strain of PPRV from Delhi. This is the first report of co-circulation of PPRV lineage IV and bluetongue virus serotype 12 in the state.

Abstract
Setting: While surgery for pulmonary tuberculosis (PTB) is considered an important adjunct for specific cases, including drug-resistant tuberculosis, operational evidence on its feasibility and effectiveness is limited. Objective: To describe surgical outcomes and programmatic challenges of providing surgery for PTB in Mumbai, India. Design: A descriptive study of routinely collected data of surgical interventions for PTB from 2010 to 2014 in two Mumbai hospitals, one public, one private. Results: Of 85 patients, 5 (6%) died and 17 (20%) had complications, with wound infection being the most frequent. Repeat operation was required in 12 (14%) patients. Most procedures were performed on an emergency basis, and eligibility was established late in the course of treatment. Median time from admission to surgery was 51 days. Drug susceptibility test (DST) patterns and final treatment outcomes were not systematically collected. Conclusion: In a high-burden setting such as Mumbai, important data on surgery for PTB were surprisingly limited in both the private and public sectors. Eligibility for surgery was established late, culture and DST were not systematically offered, the interval between admission and surgery was long and TB outcomes were not known. Systematic data collection would allow for proper evaluation of surgery as adjunctive therapy for all forms of TB under programmatic conditions.

Abstract
Mucopolysaccharidoses (MPS), a subgroup of lysosomal storage disorders, are caused due to deficiency of specific lysosomal enzyme involved in catabolism of glycosaminoglycans. To date more than 200 pathogenic variants in the alpha-l-iduronidase (IDUA) for MPS I and ∼500 pathogenic variants in the iduronate-2-sulphatase (IDS) for MPS II have been reported worldwide. The mutation spectrum of MPS type I and MPS type II disorders in Indian population is not characterized yet. In this study, we carried out clinical, biochemical, molecular and in silico analyses to establish the mutation spectrum of MPS I and MPS II in the Indian population. We conducted molecular analysis for 60 MPS-affected patients [MPS I (n = 30) (Hurler syndrome = 17, Hurler-Scheie syndrome = 13), and MPS II (n = 30) (severe = 18, attenuated = 12)] and identified a total of 44 [MPS I (n = 22) and MPS II (n = 22)] different pathogenic variants comprising missense, nonsense, frameshift, gross deletions and splice site variants. A total of 20 [MPS I (n = 14), and MPS II (n = 6)] novel pathogenic sequence variants were identified in our patient cohort. We found that 32% of pathogenic variants detected in IDUA were recurrent and 25% in MPS II. This is the first study revealing the mutation spectrum of MPS I and MPS II patients in the Indian population.

Abstract
Superficial dorsal penile vein thrombosis (penile Mondor's disease (MD)) is a unique and reportedly uncommon condition. Many cases of penile MD are idiopathic, but it is often precipitated by trauma, sexually transmitted infections and different sexual practices, such as vigorous sexual activity and the use of sexual devices. We describe the case of a young active duty man diagnosed with a penile MD, preceded by an intense sexual activity. Once diagnosed, a supportive care was instituted, consisting of administration of non-steroidal anti-inflammatory drug, temporary sexual abstinence and proper patient reassurance with complete recovery. We believe that military physicians, who care for a majority of young and sexually active adults, must be familiar with the diagnosis of penile MD and its treatment. To the best of our knowledge, this is the first case of penile MD to be reported in a military setting.

Abstract
Temporal lobe epilepsy (TLE) is the most common focal seizure disorder in adults. In many patients, transient brain insults, including status epilepticus (SE), are followed by a latent period of epileptogenesis, preceding the emergence of clinical seizures. In experimental animals, transcriptional upregulation of CaV3.2 T-type Ca(2+)-channels, resulting in an increased propensity for burst discharges of hippocampal neurons, is an important trigger for epileptogenesis. Here we provide evidence that the metal-regulatory transcription factor 1 (MTF1) mediates the increase of CaV3.2 mRNA and intrinsic excitability consequent to a rise in intracellular Zn(2+) that is associated with SE. Adeno-associated viral (rAAV) transfer of MTF1 into murine hippocampi leads to increased CaV3.2 mRNA. Conversely, rAAV-mediated expression of a dominant-negative MTF1 abolishes SE-induced CaV3.2 mRNA upregulation and attenuates epileptogenesis. Finally, data from resected human hippocampi surgically treated for pharmacoresistant TLE support the Zn(2+)-MTF1-CaV3.2 cascade, thus providing new vistas for preventing and treating TLE.

Abstract
OBJECTIVE Poor adherence to treatment may contribute to the treatment gap in chronic obstructive pulmonary diseases (COPD). The aim of the current study was to describe the association between adherence to treatment and the risk of COPD moderate (ME) and severe (SE) exacerbations, and health care utilization. RESEARCH DESIGN AND METHODS Observational single cohort study utilizing the Quebec Provincial Health Insurance databases. All patients older than 40 years with a diagnosis of COPD between 2001 and 2010 were entered in the study cohort at the time of their first prescription for tiotropium (TIO) alone or co-administered with fluticasone propionate/salmeterol (TIO + FSC). Follow-up continued to the last known claim or death. Adherence was measured by the medication possession ratio (MPR) ≥80% and persistence defined as no treatment gap ≥30 days. MAIN OUTCOME MEASURES ME was defined as use of an oral corticosteroid or antibiotic, SE as COPD related hospitalization or an emergency room (ER) visit. COPD related health care resource utilization ascertained was prescription of rescue medications, ER visits, hospitalizations, intensive care unit (ICU) admissions, intubations, and general practitioner (GP) and respirologist visits. RESULTS There were 23,707 patients included in this study. Compliance and persistence with TIO for monotherapy patients were 61.1% and 47.6% respectively. For patients treated with TIO + FSC, compliance and persistence for TIO were 62.9% and 45.3% respectively, and for FSC they were 35.4% and 33.0%. Multivariate analyses showed a significant (P < 0.001) adjusted odds ratios for ME (OR(ME)) and SE (OR(SE)) for TIO compliant vs. non-compliant patients (TIO: OR(ME) = 0.543, OR(SE) = 0.712; TIO + FSC: OR(ME) = 0.436, OR(SE) = 0.570). Similarly for FSC compliance: OR(ME) = 0.546; OR(SE) = 0.749. Similar results were observed for persistence. Compliance and persistence with TIO and FSC were associated with significantly reduced rates of health care utilization. CONCLUSIONS Despite the typical limitations of an administrative database study, the results of this large population-based study have shown that reduced adherence to treatment with TIO and FSC is associated with increased risk for exacerbations and higher health care utilization in COPD patients.

[Isotretinoin and exercise: can the two walk together?]. HAREFUAH 2014; 153:104-125. [PMID: 24716429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/03/2023]
Abstract
Since its introduction in 1982, isotretinoin has revolutionized acne treatment, targeting the underlying mechanism of the disease, with effective and long-lasting results. During the first decade of its marketing, several cases of hyperCKemia and rhabdomyolysis were linked to isotretinon therapy. A special concern was given to the possible triggering of muscle toxicity by vigorous exercise. These potential effects discouraged the prescription of isotretinoin to physically active patients or required them to abstain from exercise during treatment. Common musculoskeletal adverse effects of isotretinoin include muscle or joint pains. HyperCKemia is frequently found in patients receiving treatment for rare cases of rhabdomyolysis. Isotretinoin-associated muscle toxicity is usually detected in asymptomatic patients, even though symptoms can appear without hyperCKemia. A possible synergistic effect of isotretinoin and exercise is plausible, although supported by weak evidence and mediated by an unknown mechanism. There are only two reports of myoglobinuria and no reports of decreased renal function in exercising patient under treatment. In conclusion, we believe that current data should not deter physicians from offering isotretinoin to physically active patients nor require them to abstain from exercise. Physicians must explain to patients the possible side effects of treatment, ask them to refrain from an unusual change in their exercise regimen and advise them to avoid other triggers of rhabdomyolysis. Patients should be aware of possible signs of muscle toxicity and inform their doctors about any relevant symptoms.

Abstract
Chromosomal rearrangements associated with a disease play a significant role in the phenotypic manifestation. Here we report a 9-month-old girl with de novo partial proximal trisomy 14 with seizures and global developmental delay. Cytogenetic investigations revealed a karyotype of 47,XX+marker. The marker was approximately the size of G-group chromosomes and almost mistaken as chromosome 22 due to its banding pattern but the trisomy 22 was ruled out considering its lethality. To find out the origin of the marker chromosome, Spectral karyotyping (SKY) was performed which showed the marker to be of chromosome 14 origin. Further Molecular cytogenetic analysis with whole chromosome 14 confirmed the marker as a derivative 14. Fluorescence in situ hybridization (FISH) with centromeric probe 14 also showed 3 signals. Further fine mapping with three Bacterial Artificial Chromosome clones helped us to tentatively find the extent of the break point regions. The use of SKY and FISH permitted the characterization of this cytogenetic abnormality. The clinical data of the present case are compared with other published cases in the literature. This helps in better genetic counseling and also in the genotype/phenotype correlation. The impact of the extra chromosomal part in relation with the phenotype of the patient is also discussed.

Abstract
Toxoplasma gondii is an ubiquitous parasite with a prevalence variable from country to country. In Morocco very few studies were devoted to this prevalence. To fill this gap we were interested to study the epidemiology of this parasite and to know the level of carriage by the different vectors which are the sources of contamination in humans. The study was done by directly detecting the cysts in the cerebral tissue of the 50 sheep killed and destined for consumption. The results of this preliminary study show that 30% of the cases carry the cysts of T. gondii. To confirm this result and verify the virulence, cerebral specimens were inoculated into mice. These findings are encouraging to complete this study with serological tests and to look for the parasite in cows and goats of this region.

Abstract
In the aftermath of the devastating Haitian earthquake, we became the primary relief service for a large group of severely injured earthquake victims. Finding ourselves virtually isolated with extremely limited facilities and a group of critically injured patients whose needs vastly outstripped the available resources we employed a disaster triage system to organize their clinical care. This report describes the specific injury profile of this group of patients, their clinical course, and the management philosophy that we employed. It provides useful lessons for similar situations in the future.

Abstract
BACKGROUND & AIMS Late-onset symptoms of urea-cycle disorder may lead to a life-threatening disease which is often undetected. We report the clinical and metabolic manifestations of acute hyperammonemic encephalopathy in a 47-year-old asymptomatic man with ornithine transcarbamylase (OTC) deficiency. The hyperammonemic encephalopathy was unmasked by a high-protein Atkins diet. METHODS Genetic analysis of the patient's family, 89 unrelated Ashkenazi Jewish and 50 unrelated Europeans subjects was performed using polymerase chain reaction amplification and DNA sequencing of the OTC gene. RESULTS Treatment with hemodialysis, provision of adequate calories to prevent catabolism, and protein elimination for 24h followed by protein restriction and ammonia scavenging medications effectively lowered the patient's plasma ammonia level and resulted in full recovery. Genetic analysis of the OTC gene revealed a novel hemizygous missense mutation in exon 5 (c.477T>G), leading to an isoleucine-to-methionine substitution in codon 159 (Ile159Met). Further genetic analysis of the patient's family yielded the mutation in many of them, although findings were negative in 89 unrelated Ashkenazi Jewish and 50 unrelated Europeans subjects. CONCLUSIONS This is the first reported case of an adult urea-cycle defect unmasked by the Atkins diet. Measurements of serum ammonia level must be part of the basic work-up in all patients presenting with encephalopathy of unknown origin even in the absence of liver dysfunction. Awareness of this important association can contribute to prompt diagnosis and life-saving treatment. Correct diagnosis is also important to prevent future recurrences and to provide genetic counselling for family members.

Abstract
The objective of the present study was to evaluate the in vitro and in vivo anti-cancer effect of Nigella sativa L. seed extracts. The essential oil (IC50 = 0.6%, v/v) and ethyl acetate (IC50 = 0.75%) extracts were more cytotoxic against the P815 cell line than the butanol extract (IC50 = 2%). Similar results were obtained with the Vero cell line. Although all extracts had a comparable cytotoxic effect against the ICO1 cell line, with IC50 values ranging from 0.2 to 0.26% (v/v), tests on the BSR cell line revealed a high cytotoxic effect of the ethyl acetate extract (IC50 = 0.2%) compared to the essential oil (IC50 = 1.2%). These data show that the cytotoxicity of each extract depends on the tumor cell type. In vivo, using the DBA2/P815 (H2d) mouse model, our results clearly showed that the injection of the essential oil into the tumor site significantly inhibited solid tumor development. Indeed, on the 30th day of treatment, the tumor volume of the control animals was 2.5 +/- 0.6 cm(3), whereas the tumor volumes of the essential oil-treated animals were 0.22 +/- 0.1 and 0.16 +/- 0.1 cm(3) when the animals were injected with 30 microL (28.5 mg)/mouse and 50 microL (47.5 mg)/mouse per 48 h (six times), respectively. Interestingly, the administration of the essential oil into the tumor site inhibited the incidence of liver metastasis development and improved mouse survival.
