Swimming through sand: using accelerometers to observe the cryptic, pre-emergence life-stage of sea turtle hatchlings.

Animals that hatch within a subterranean nest, such as turtle hatchlings, expend some of their limited energy reserves digging out through sand or soil to reach the surface. In sea turtles, this emergence process can take the hatchlings 3-7 days. However, we have a poor understanding of this process as it is difficult to observe what is occurring underground. Here, we utilize a novel method to characterize digging-out behaviour: affixing an accelerometer directly to newly hatched green turtles (Chelonia mydas) to record movement until nest emergence. Our data revealed that buried hatchlings maintained a head-up orientation but did not move in the expected left and right swaying motion associated with alternating limb crawling. Rather, they moved using dorsal-ventral heaving and pitching as if swimming vertically through the sand to the surface. Movement activity was irregular and brief, interspersed by many short periods of inactivity, mostly lasting less than 10 min. The first 24 h of head-up activity displayed no diel patterns, but the last 24 h prior to emergence involved more intense movement during night-time hours compared with daytime hours. Thus, our results add valuable new insight, and in some cases change previous assumptions, regarding the digging behaviours during the egg-to-emergence life stage in sea turtles.

Metastatic Cutaneous Basal Cell Carcinoma: Report of 2 Cases Preceding the Hedgehog Pathway Antagonists Era.

Basal cell carcinoma (BCC) of the skin is the most common type of malignant human tumor. However, metastatic BCC is a very rare event with weakly effective therapeutic options and a poor prognosis, until a few years ago. In 2012, small-molecule therapies, capable of inactivating the hedgehog signaling pathway and thus reducing tumor growth and progression, were introduced into clinical practice for the treatment of patients with advanced BCC. We present retrospectively 2 personal cases of metastatic BCC of the skin, from the premolecular therapy era, from primary tumors that arose years before in the head and neck area. The former case occurred in a 45-year-old woman with a history of recurrent BCC of the retroauricular skin who eventually died due to diffuse metastatic spread. The latter case concerned a 70-year-old man also with a history of recurrent BCC of the nasal-perinasal skin who developed multiple subcutaneous and lymph node metastases in the neck. In both cases, the diagnoses were based on biopsies of the metastatic sites. The first patient died 5 months after the diagnosis of metastatic disease, while the second was alive and disease-free 2 years after neck lymph node dissection and external radiation therapy, and then lost to follow-up. We extensively discuss several tumor entities with basal or basaloid features that may enter the differential diagnosis with BCC in metastatic sites. In addition, we briefly summarize the advances in clinical therapeutics using small molecules, which are now an integral part of the treatment of such advanced BCC cases.

Metastatic Basal Cell Carcinoma of the Skin: A Comprehensive Literature Review, Including Advances in Molecular Therapeutics.

Basal cell carcinoma (BCC) of the skin is the most common type of malignant human tumor. In Europe, the incidence of BCC ranges from 44.6 to 128 cases per 100,000 inhabitants annually, whereas in the United States, the yearly incidence rate ranges between 500 and 1500. The global incidence has been calculated to be as high as 10 million cases of BCC per year. There are 2 main clinical patterns of BCC-the familial BCC in basal cell nevus syndrome and sporadic BCC. The etiology of cutaneous BCC is usually the result of the interaction between solar ultraviolet radiation and genetic factors. Somatic or germline mutations in the effector components of the hedgehog signaling pathway (ie, PTCH1, PTCH2, SMO or SUFU genes) are responsible for ∼90% of the cases of both sporadic and familial BCC, all causing a constitutive activation of the hedgehog pathway. Cutaneous BCC very rarely metastasizes, and diagnosis in metastatic sites can be very difficult. Metastatic BCC has weakly effective therapeutic options with a poor prognosis until few years ago. In 2012, small-molecule therapies, involving inactivation of the hedgehog signaling pathway, and capable of reducing tumor growth and progression have been introduced into clinical practice for advanced (locally advanced or metastatic) BCC. We performed a comprehensive literature review on metastatic BCC and found at least 915 cases reported to date. In addition, we extensively discussed the differential diagnosis of metastatic BCC, and outlined the advances in clinical therapeutics involving these small molecules.

Anaplastic Kaposi's Sarcoma of the Adrenal in an HIV-negative Patient With Literature Review.

Kaposi's sarcoma (KS) is a peculiar tumor of viral etiology, with the HHV8 rhadinovirus playing a fundamental role in its development. Several epidemiological categories of KS have been identified, of which the sporadic, endemic, iatrogenic, and the epidemic are the main ones. Several histologic disease morphologies have been described, such as inflammatory, angiomatous, spindle cell, mixed, and the anaplastic (sarcomatous) subtypes. The skin of the limbs is most commonly affected, but any other organ or site may be involved. Microscopically KS may enter the differential diagnosis with several different entities, and for this purpose the immunohistochemical detection of the viral latent nuclear antigen-1 (LNA-1) may be crucial. Sporadic KS is usually benign, but rarely it may be aggressive. Anaplastic histology heralds an ominous course in any clinical context. We report a case of anaplastic retroperitoneal KS, occurring in an HIV-negative adult man. This patient presented with a huge left suprarenal mass, which was totally resected, and initially diagnosed as inflammatory leiomyosarcoma, because of the monomorphic spindle cell tumor morphology. After 12 years the tumor recurred locally as an unresectable mass, which was biopsied and examined. At the time of recurrence, the histologic slides of the primary tumor were reviewed, and the previous diagnosis was changed to that of atypical KS. Histologically the recurrent tumor showed both spindle cell and epithelioid appearances. Strongly diffuse HHV8/LAN-1 immunopositivity was documented in both tumors. The final diagnosis for the entire case was anaplastic KS. Then, the patient died in a few months.

Extraneuraxial Hemangioblastoma: Clinicopathologic Features and Review of the Literature.

Extraneuraxial hemangioblastoma occurs in nervous paraneuraxial structures, somatic tissues, and visceral organs, as part of von Hippel-Lindau disease (VHLD) or in sporadic cases. The VHL gene plausibly plays a key role in the initiation and tumorigenesis of both central nervous system and extraneuraxial hemangioblastoma, therefore, the underlying molecular and genetic mechanisms of the tumor growth are initially reviewed. The clinical criteria for the diagnosis of VHLD are summarized, with emphasis on the distinction of sporadic hemangioblastoma from the form fruste of VHLD (eg, hemangioblastoma-only VHLD). The world literature on the topic of extraneuraxial hemangioblastomas has been comprehensively reviewed with ∼200 cases reported to date: up to 140 paraneuraxial, mostly of proximal spinal nerve roots, and 65 peripheral, 15 of soft tissue, 6 peripheral nerve, 5 bone, and 39 of internal viscera, including 26 renal and 13 nonrenal. A handful of possible yet uncertain cases from older literature are not included in this review. The clinicopathologic features of extraneuraxial hemangioblastoma are selectively presented by anatomic site of origin, and the differential diagnosis is emphasized in these subsets. Reference is made also to 10 of the authors' personal cases of extraneuraxial hemangioblastomas, which include 4 paraneuraxial and 6 peripheral (2 soft tissue hemangioblastoma and 4 renal).

Mitigating risks of students use of study drugs through understanding motivations for use and applying harm reduction theory: a literature review.

As postsecondary students' use of "study drugs" becomes more popular with increasingly reported negative effects on health and academic performance, failing prohibitionist policies to reduce consumption, and ambiguity in literature towards best practices to address this population, we present a literature review that seeks effective solutions educational institutions can apply to improve outcomes for students who use drugs. Motivations for use, effects of the substances, an analysis of efforts to control use from educational institutions, and suggestions on promoting most effective outcomes based on harm reduction, are described. Theory, quantitative, and qualitative works from systematic reviews, cohort studies, and epidemiological assessments are examined on the "study drugs" methylphenidate, dextroamphetamine, and amphetamine, also known as Adderall, Ritalin, Focalin, and Concerta. There is a focus on postsecondary students ages 18-25 in North America. Results show important risk factors for drug use including low perceived self-efficacy or enjoyment in courses, poor accommodation of special needs, reliance on external validation, having a low GPA, and experiencing a mental health issue. There is much misconception on the health and academic effects of these drugs in literature, among students, and on online knowledge sources. We suggest these drugs do not improve GPA and learning, while they might temporarily increase memory, but with detrimental negative health effects. Campaigns that address underlying factors of use can be most successful in mitigating harms.

Lipophyllodes of the breast. A reappraisal of fat-rich tumors of the breast based on 22 cases integrated by immunohistochemical study, molecular pathology insights, and clinical follow-up.

We have studied 22 cases of mammary lipophyllodes tumors (LPT), analyzing their clinicopathologic features along with available follow-up. All cases were tested for cytokeratins, S100 protein, and MDM2, and in selected cases for estrogen receptor, smooth muscle actin, bcl2, desmin, and myogenin. Patients were women aged 21 to 69 years (average, 45 years), and LPT size ranged from 1.6 to 30 cm (average, 9.7 cm). Microscopically, LPT segregated as follows: atypical lipoma-like tumor/well-differentiated liposarcoma (ALT/WDL), 8 cases; myxoid, 6; and pleomorphic/poorly differentiated/round cell, 8, including a case of dedifferentiated liposarcoma. Immunohistochemistry studies showed focal positive staining for S100 and CD34 in most ALT/WDL, and desmin and myogenin in 2 cases with evidence of rhabdomyoblastic differentiation. MDM2 positivity was focally seen in 1 case. Follow-up was available in 8 cases. Multiple recurrent tumors were seen in 2 patients, and metastatic disease to the lung was seen in 2 patients. In 4 patients with a follow-up between 2 and 15 years there was no evidence of recurrent or metastatic disease. Patients with ALT/WDL (2/2) were alive with no evidence of disease; 2 of 4 patients with myxoid liposarcoma component experienced tumor recurrence, whereas pleomorphic liposarcoma LPT pursued a less favorable course although only 1 patient died of the condition. Absence of MDM2 reactivity in most cases seems not as meaningful as in fatty tumors of somatic soft parts.

Unmasking of proteinuria in the course of genetic dissection of nonproteinuric diabetic nephropathy.

We previously described the development of nonproteinuric diabetic nephropathy (NPDN) in the Cohen diabetic rat (CDs), a model that simulates Type 2 diabetes in humans. Using linkage analysis in an F2 cross, we currently set out to investigate the mechanisms underlying NPDN. We crossbred between CDs and SBN/y, a nondiabetic rat strain, generated F1 and F2 progenies, fed them diabetogenic diet that elicits diabetes and NPDN in CDs but not in SBN/y, and determined metabolic and renal phenotypes. Over 5 mo, ∼75% of F2 developed a diabetic phenotype. In parallel, a nephropathy developed in F2, with glomerular filtration rate (GFR) declining in ∼25% and, unexpectedly, significant proteinuria appearing in ∼75%. We scanned the F2 genome with microsatellite markers and used linkage analysis to identify quantitative trait loci (QTLs). We detected diabetes-related QTLs on RNO4 and 13. We also detected two QTLs for the decline in GFR on RNO4 and 13 and another QTL for proteinuria on RNO13. The metabolic and renal-related QTLs overlapped. These results suggest that the mechanisms underlying the nephropathy in F2 are related to genes that map to RNO4 and 13, as well as a common genetic background for the development of diabetes and the renal disease. Our findings further indicate that proteinuria is inhibited in parental diabetic CDs, thus accounting for the nonproteinuric phenotype, but "unmasked" in diabetic F2 whose genome has been modified. Identifying the nature of the factor inhibiting proteinuria in diabetic CDs but not in F2 may provide a clue to treatment and prevention of proteinuria in diabetes.

Selected case from the Arkadi M. Rywlin International Pathology Slide Series: Leiomyomatosis peritonealis disseminata: report of 3 cases with extensive review of the literature.

We present the clinicopathologic features of 3 cases of leiomyomatosis peritonealis disseminata (LPD). The patients were 33, 34, and 41 years old at the time of diagnoses. The 3 women had undergone laparoscopic removal of multiple uterine leiomyomas between 1 and 6 years before the diagnoses of LPD. Laparoscopic uterine leiomyomectomies were performed on 3 occasions in patient 1, and once in patients 2 and 3 by the time a diagnosis of LPD was made. In patients 2 and 3, one of the multiple uterine leiomyomas had been qualified as mitotically active. Patients 1 and 2 received hormonal treatment before LPD was diagnosed. Malignancy was clinically and/or pathologically suspected in all the 3 cases. Patients 1 and 2 were managed conservatively. Patient 3 underwent radical hysterectomy with bilateral adnexectomy and omentectomy. Patients 1 and 2 belong to a rare subset of LPD that have fewer tumor nodules larger (5 to 10 cm) than typically seen. Patient 3 was classic in that she exhibited innumerable nodules measuring between a few millimeters and 1.5 cm, intraoperatively mimicking peritoneal carcinomatosis. Histopathologically, patients 1 and 2 were diagnosed as pure LPD, whereas patient 3 was diagnosed as LPD associated with endometriosis (adenomyosis type). Patients 1 and 3 had incipient foci of leiomyomatous changes in the blood vessel walls, at the site of the LPD tumors, supporting the hypothesis that these are de novo lesions arising locally and not migrated or disseminated from the previously excised or concurrent uterine smooth muscle tumors, usually seen in this context. Conceivably, laparoscopic leiomyomectomy with morcellation may play a role in the pathogenesis of this rare condition, at least in hormonally susceptible patients. Alternatively, LPD may derive from metaplastic submesothelial cells, a condition analogous to gliomatosis peritonei.

Characterizing the clinical and sociodemographic profiles of hospitalized adolescents with autism spectrum disorder.

The prevalence of autism spectrum disorder (ASD) is increasing worldwide. Youngsters with ASD demonstrate higher rates of intellectual disabilities (IDs), comorbid psychopathology and psychiatric hospitalizations, compared to children in the general population. This study characterizes the demographics and clinical parameters of adolescent psychiatric inpatients with ASD compared to inpatients without ASD, all hospitalized during the study period. Additionally, within the ASD group, those with ID were compared to those without. The rate of males among participants with ASD was significantly higher than among those without ASD, and the duration of hospitalization was longer. In contrast, the rate of cigarette smoking, major depressive disorder and suicidal thoughts among those with ASD was lower. One-third of those with ASD had moderate to severe ID, about 10% had comorbid epilepsy, and about half of them demonstrated aggressive behavior. Most ASD patients showed significant improvement upon discharge, although the extent of improvement was more prominent among ASD patients with no ID. Our findings, consistent with previous research, indicate that hospitalization is beneficial to youths with ASD, both those with and those without ID. Further studies that include long-term follow-up are needed.

Radical cystectomy with W-shaped orthotopic ileal neobladder constructed with non-absorbable titanium staples-long term follow-up.

PURPOSES: We retrospectively assessed our experience with the W-shaped orthotopic ileal pouch, which was constructed with non-absorbable titanium staples. For these purpose, we discuss the results of bladder capacity, urinary continence and early and long-term postoperative complications. MATERIALS AND METHODS: We included in the study 17 patients who underwent radical cystoprostatectomy followed by construction of an orthotopic W-shaped ileal pouch between October 2000 and November 2009. A 65-70 cm segment of ileum was isolated and prearranged into a W-configuration, leaving two 10 cm intact segments on both sides of the ileal fragment. In our technique we entirely anatomized all adjacent limbs in order to create a sphere-shaped pouch. The ureters were directly anastomized to both intact segments of the ileal division. All our patients underwent pouchscopy 6 months after operation and annually. RESULTS: Mean operative time for neobladder reconstruction and ureteral anastomoses was 87 ± 7.67 minutes. In one patient a leak from the ileo-ileal anastomosis was confirmed on the 3rd day after operation. In 2 cases unilateral stricture of the ureteral-neobladder anastomosis was documented. Staple lines were mostly covered with ileal mucosa after 6 months. The mean functional bladder capacity was 340 ± 27.6 mL and 375 ± 43.4 mL at 6 and 12 months, respectively. First-year daytime and nighttime continence was good and acceptable in 90% and 78% of patients, while it increased to 95% during the 2nd year. CONCLUSIONS: The long term follow-up shows that non-absorbable titanium staples can be safely used for creation of an orthotopic ileal neobladder. However, these data should be further validated in a larger series of patients.

Association between neutrophil to lymphocyte ratio and mood polarity in adolescents admitted to an inpatient psychiatric ward.

Inflammatory processes are associated with mood disorders, but data on pediatric patients are scarce. The aim of this study was to investigate a possible association between elevated neutrophil/lymphocyte ratio (NLR) - a marker of inflammation and mood polarity (manic/depressed) in adolescents, admitted between 2010 and 2015 due to a mood disorder episode and to an adolescent inpatient ward. Electronic medical records of 305 patients (aged 10-19 years, 60.6% males) admitted during the study period due to a mood disorder episode were reviewed. Of these, 63 were diagnosed with manic episodes and 242 with depressive episodes. Multivariate analyses were used to compare NLR between and within the two groups, covarying for age, sex, and antipsychotic use. NLR was significantly higher in the manic episode group compared with the depression one. Moreover, in inpatients with multiple hospitalizations, the NLR was higher during their manic episodes than that during their nonmanic states. These results suggest that, as has been reported in adults with bipolar disorder, inflammatory mechanisms may be involved in adolescents' mood disorders as well, particularly in the manic episodes. Thus, clinicians may consider adding anti-inflammatories as part of the treatment of these patients.

Phenotypic Characterization of Youth Admitted To Acute Psychiatric Inpatient Unit Following Self-Harm Behavior.

OBJECTIVE: Deliberate self-harm (DSH) is a major health concern among adolescents, and is often associated with the need for inpatient psychiatric hospitalization. The aim of this study was to identify clinical and demographic characteristics associated with DSH behavior among adolescents admitted to an acute psychiatric inpatient unit. METHOD: We retrospectively analyzed data from the electronic medical records of consecutive admittances to a single acute adolescent inpatient unit (n = 703, mean age 15.2). We compared inpatients with DSH to inpatients without DSH and further compared within the DSH group based on the presence of suicidal intent. RESULTS: Compared to Non-DSH inpatients (n = 497), youths admitted following DSH (n = 206) were more likely to be female (OR = 2.6, 95%CI 1.7-4), currently in depressive exacerbation (OR = 2.4, 95%CI 1.6-3.6), with concurrent suicidal ideation (OR = 3.9, 95%CI 2.5-5.9), and history of alcohol use (OR = 5.6, 95%CI 3.2-9.5). Within DSH youths, no significant clinical differences were identified between those admitted following a suicide attempt (n = 102) compared to non-suicidal-self-injury (n = 104), who were generally younger. CONCLUSIONS: Findings suggest that early detection and intervention of DSH and depressive crisis is warranted, regardless of the self-harm subtype.HIGHLIGHTSDeliberate self-harm is common among adolescent psychiatric inpatients.Adolescent inpatients with deliberate self-harm are predominantly females with concurrent depression and suicidal ideation.We did not detect significant clinical and demographic differences between self-harmers with or without suicidal intent.

Solitary fibrous tumor of the central nervous system: a 15-year literature survey of 220 cases (August 1996-July 2011).

We reviewed the world literature on solitary fibrous tumors of the central nervous system from August 1996 to July 2011, focusing on both clinicopathological features and diagnostic findings. The anatomical distribution of the 220 cases reported so far reveals that most are intracranial and just over one-fifth are intraspinal. In decreasing frequency, intracranial tumors involve the supratentorial and infratentorial compartments, the pontocerebellar angle, the sellar and parasellar regions, and the cranial nerves. Intraspinal tumors are mainly located in the thoracic and cervical segments. Although most solitary fibrous tumors of the central nervous system are dural based, a small subset presents as subpial, intraparenchymal, intraventricular, or as tumors involving the nerve rootlets with no dural connection. Preoperative imaging and intraoperative findings suggest meningioma, schwannoma or neurofibroma, hemangiopericytoma, or pituitary tumors. Immunohistochemistry is critical to establish a definitive histopathological diagnosis. Vimentin, CD34, BCL2, and CD99 are the most consistently positive markers. The usual histologic type generally behaves in a benign manner if complete removal is achieved. Recurrence is anticipated when resection is subtotal or when the tumor exhibits atypical histology. The proliferative index as assessed by MIB1 labeling is of prognostic significance. Occasionally, tumors featuring conventional morphology may recur, perhaps because of minimal residual disease left behind during surgical extirpation. Rare extracranial metastases and tumor-related deaths are on record. Surgery is the treatment of choice. Stereotactic and external beam radiation therapy may be indicated for postsurgical tumor remnants and for unresectable recurrences. Long-term active surveillance of the patients is mandatory.

Paratesticular mesothelioma. Report of a case with comprehensive review of literature.

Paratesticular mesotheliomas are rare tumors with 223 cases described so far. The sole plausible causative factor so far ascertained in the pathogenesis of these tumors is asbestos, which however is found in only around 30% to 40% of such cases. The age range of affected individuals is wide, mostly adults and the elderly, but also includes young people and children. The most common presenting symptom is either hydrocele of unknown origin or intrascrotal mass. When hydrocele is the presenting symptom, these tumors are often clinically overlooked and the diagnosis is delayed. Most paratesticular mesotheliomas arise in the tunica vaginalis, but primary tumors of the spermatic cord and epididymis are also on record. Tumors arising from the peritoneal mesothelium of a hernia sac are excluded from this group. The correct diagnosis is almost always made after histologic examination of the operative specimen. Immunohistochemistry and electron microscopy are always helpful and sometimes necessary tools for diagnosis. So far very few cases have been identified or suspected preoperatively on cytologic examination. Three clinicopathologic types of malignant mesotheliomas of the male genital tract are recognized: diffuse tubulo-papillary mesothelioma, well-differentiated papillary mesothelioma, and multicystic mesothelioma. The histologic subtypes are almost always pure epithelial or biphasic. The differential diagnosis is mainly with serous papillary tumors arising from Mullerian vestiges, but several diverse primary or secondary tumors also need to be considered. A clinicopathologic evaluation of a case of tunical diffuse mesothelioma in a 74-year-old male from the AMR Series is the starting point for this general review.

Selected case from the Arkadi M. Rywlin International Pathology Slide Seminar: Sporadic lymphangioleiomyomatosis.

Lymphangioleiomyomatosis (LAM) is a systemic, progressive, and fatal condition affecting almost exclusively women in their reproductive years. LAM most often occurs as a sporadic disease, but also occurs in women with tuberous sclerosis complex (TSC) (syndromic LAM). There are no pathologic differences between sporadic and syndromic LAM. Sporadic LAM is a rare disease with prevalence of approximately 1 to 2 cases per million women in the United States and among populations of white descent, and is even rarer among Asian and African individuals. Syndromic LAM affects 4% to 5% of women with TSC. Sporadic LAM is often found also in association with renal angiomyolipoma, the most common sign of TSC, but LAM associated with angiomyolipoma does not define TSC. Although LAM is not diagnostic for TSC either in isolation or in association with angiomyolipoma, still it is considered by some researchers as an incomplete expression (forme fruste) of TSC. LAM may involve the lungs and the axial lymphatics and lymph nodes of the thorax and retroperitoneum. In sporadic LAM, thoracic, intraabdominal, and cervical lymph nodes can be involved with or without lung involvement. The diagnosis of LAM is often delayed. A case of LAM in a young lady, which was complicated with pleural and peritoneal chylous effusions, is presented. The diagnosis was first made on a retroperitoneal lymph node biopsy. The patient had a prolonged prior history of respiratory problems owing to lung involvement, and eventually died 2 years after diagnosis. Focus on the clinicopathologic diagnosis of TSC is also made.

Predictors of Suicidal Behaviors during Hospitalization among Adolescents Admitted Due to Suicidal Behaviors: A 10-Year Retrospective Naturalistic Study.

Objectives: Suicidality during hospitalization is a common phenomenon with potential devastating consequences. We attempted to identify risk factors for in-hospital suicidality in a high risk group of adolescent inpatients hospitalized for suicidal behaviors (SB). Methods: The database of a tertiary adolescent psychiatric ward was screened for patients hospitalized consecutively for SB during 2001-2010. Data on documented demographic, clinical, and behavioral risk factors were collected. Suicidal events during hospitalization were classified according to the Columbia Classification Algorithm of Suicide Assessment. Results: The sample included 122 inpatients (53% female) aged 10-19 (Mean=15.77, Standard Deviation=2.89) years admitted for SB. Thirty-seven youth (30%) exhibited SB during the hospitalization period (the "suicidal group"), ten of which attempted suicide while hospitalized. There were no significant differences in demographic and clinical parameters between the suicidal and the non-suicidal groups. Younger age, history of drug use and a history of non-suicidal self-injury (NSSI) were independent predictors of a SA during hospitalization. A previous SA added significant risk to SA during hospitalization only in the group that had a history of NSSI. Conclusions: A high risk of SB exists among adolescents hospitalized for suicidality. The risk assessment for SA during hospitalization should include age, history of drug use and previous SA combined with a history of NSSI. Future studies should expand the efforts to identify potential risk factors of SB during hospitalization in this unique high-risk group.

The association of non-suicidal self-injurious and suicidal behaviors with religiosity in hospitalized Jewish adolescents.

Religiosity may be a potent protective factor against self-injurious and suicidal behaviors. However, no previous study has addressed this relationship in adolescent psychiatric population. This study aimed to examine the association between religiosity and non-suicidal self-injurious (NSSI) and suicidal behaviors, among hospitalized Jewish adolescents. This is a cross-sectional study of 60 hospitalized Jewish adolescents in two mental health centers. They were evaluated for religiosity, NSSI, and suicidal behaviors. The following religiosity measures were found to be protective against NSSI: a higher degree of adherence to religious practices (extrinsic measure) (beta = -0.083, p = .006), a higher level of belief in religious principles (intrinsic measure) (beta = -0.063, p = .008) and a self-reported higher religious affinity (χ2 = 7.64, p = .022). The severity of suicidal ideation inversely correlated with the extrinsic measure (standardized beta = -0.2, t = -2.5, p = .015) and with self-reported degree of religious affinity (analysis of variance, F = 3.5, p = .035). History of transition in religious affinity was associated with worse suicidal ideation (3.77 ± 1.8 vs. 2.26 ± 1.99, t = -3.25, p = .004) and with suicide attempts (OR = 3.89 (95% CI: 1.08 - 14.03), p = .004); however, these relationships were mediated by history of abuse. This study provides first evidence of a protective effect of some religiosity measures on NSSI and suicidal behaviors in hospitalized Jewish adolescents.

A history of prolonged childhood sexual abuse is associated with more severe clinical presentation of borderline personality disorder in adolescent female inpatients - A naturalistic study.

BACKGROUND: Borderline personality disorder (BPD) is associated with high rates of suicidal and self-injurious behaviors and a substantial proportion of BPD patients have a history of trauma, particularly childhood sexual abuse (CSA). OBJECTIVE: To compare the clinical presentation severity in female adolescent inpatients with BPD with and without history of prolonged CSA. PARTICIPANTS AND SETTING: Female adolescent BPD patients admitted to a psychiatric inpatient unit. METHODS: A retrospective analysis of records of the inpatients, divided into two groups: with (n = 38) and without (n = 40) a history of prolonged CSA. Prolonged CSA was defined as sexual abuse continuing for at least 3 months. Demographic and clinical data, including number and duration of psychiatric hospitalizations until the age 19, non-suicidal self-injury (NSSI), suicide attempts, cigarette smoking, alcohol and drug use, and sexual impulsivity were compared between the two groups. RESULTS: The BPD + prolonged CSA group had a larger duration of the first psychiatric hospitalization, number of hospitalizations and cumulative length of hospitalizations compared with the control group. Furthermore, the BPD + prolonged CSA group had a higher number of suicidal attempts, and higher rates of severe NSSI events, cigarette smoking, alcohol use, and sexual impulsivity. CONCLUSIONS: This study demonstrated for the first time that adolescent female BPD inpatients with a history of prolonged CSA, manifest more severe clinical presentation compared to those without prolonged CSA. Hence, it appears essential to encourage therapists to inquire about history of CSA and refer adolescent female BPD inpatients with prolonged CSA to appropriate intensive therapy.

Tuberous sclerosis complex with polycystic kidney disease of the adult type: the TSC2/ADPKD1 contiguous gene syndrome.

Although different diseases, tuberous sclerosis complex and autosomal dominant polycystic kidney disease have been seen in association, the molecular basis of this being the proximity of tuberous sclerosis complex 2 and polycystic kidney disease 1 genes on the same chromosome (16p13.3). Therefore, the classic autosomal dominant polycystic kidney disease renal phenotype may occur in the context of tuberous sclerosis complex disease as a result of large deletions involving both the polycystic kidney disease 1 and tuberous sclerosis complex 2 genes. This is known as the tuberous sclerosis complex 2/autosomal dominant polycystic kidney disease 1 contiguous gene syndrome. The criteria for this condition are fulfilled when renal lesions typical for classic autosomal dominant polycystic kidney disease phenotype are associated with tuberous sclerosis complex phenotype. We present a new case of the sporadic form of this genetic disorder. The diagnosis of tuberous sclerosis complex in this patient was established on the presence of major and minor features, and the diagnosis of ADPKD was based on the presence of numerous large roundish renal cysts lined by a nondescript tubular epithelium. Sporadic cases of autosomal dominant polycystic kidney disease and tuberous sclerosis complex do occur. Molecular analysis was not performed because the patient's parents refused permission.
