Facial Asymmetry Caused by Mandibular Condylar Hyperplasia: A Two Center Study.

BACKGROUND: Condylar hyperplasia is a non-neoplastic overgrowth of the mandibular condyle. The disorder is progressive and causes gradual jaw deviation, facial asymmetry, and dental malocclusion. The only treatment capable of stopping hyperplastic growth is surgical condylectomy to remove the upper portion of the condyle containing the deranged growth center. When this procedure is conducted in proportion to the length of the healthy side it may also correct the jaw deviation and facial asymmetry. OBJECTIVES: To assess the degree to which condylectomy corrects the asymmetry and to determine the proportion of patients after condylectomy who were satisfied with the esthetic result and did not desire further corrective surgery. METHODS: We conducted a retrospective analysis of medical records of patients who underwent condylectomy that was not followed by corrective orthognathic surgery for at least 1 year to determine the degree of correction of chin deviation and lip cant. Patient satisfaction from treatment or desire and undergo further corrective surgery was reported. RESULTS: Chin deviation decreased after condylectomy from a mean of 4.8° to a mean of 1.8° (P < 0.001). Lip cant decreased after condylectomy from a mean of 3.5° to a mean of 1.5° (P < 0.001). Most patients (72%) were satisfied with the results and did not consider further corrective orthognathic surgery. CONCLUSIONS: Proportional condylectomy could be a viable treatment to both arrest the condylar overgrowth and achieve some correction of the facial asymmetry.

Bromelain-based enzymatic debridement of chronic wounds: Results of a multicentre randomized controlled trial.

Chronic wounds are estimated to affect over 6 million people annually in the United States with an estimated annual cost of $25 billion. Debridement represents a key step in their management and is considered a basic necessity to induce the functional process of tissue repair. However, there is an unmet need for an efficient rapid acting non-surgical debridement agent. Bromelain-based enzymatic debridement has been proven to provide an effective, selective and safe non-surgical debridement in deep burns. EscharEx (MediWound Ltd, Yavne, Israel), is a bromelain-based enzymatic debridement agent currently in development for chronic wounds. The aim of this study was to assess its safety and efficacy in chronic wounds. Seventy-three patients suffering from a lower extremity ulcer of diabetic/venous insufficiency/post-surgical/traumatic aetiology were enrolled in a multicentre, assessor blinded, randomized controlled trial. Patients were randomized to topical treatment by either EscharEx or its gel vehicle for up to 10 daily 4 hour applications, and then continued follow-up for up to 6 months. The EscharEx arm achieved a significantly higher incidence of complete debridement compared to the gel vehicle arm; 55 versus 29% (p = .047), thus meeting the primary endpoint of this study. The EscharEx and gel vehicle arms achieved similar reductions in wound area, non-viable tissue area and wound healing scores during the debridement period. There were no significant differences between the arms in the incidence of complete wound closure (41% in the EsxcharEx arm vs. 53% in the gel vehicle arm) and in the mean time to complete wound closure (70.0 ± 32.8 days in the EsxcharEx arm vs. 65.7 ± 38.4 days in gel vehicle arm). There were no significant safety issues and EscharEx demonstrated a favourable benefit to risk profile.

Case Report of Two Patients With COVID-19 and Sacral Pressure Injuries Associated with Pyoderma Gangrenosum.

ABSTRACT: During the COVID-19 pandemic, an increasing number of patients have been admitted to the ICU with severe respiratory complications requiring prolonged supine positioning. Recently, many case reports have been published regarding dermatologic manifestations associated with COVID-19. However, there is little information about the clinical features of these manifestations. Pyoderma gangrenosum (PG) is an ulcerative noninfectious inflammatory disease of the skin. In at least 50% of the cases, the etiology is unknown. Nevertheless, PG is associated with many systemic diseases. In this article, the authors report two critically ill patients with COVID-19 who developed sacral ulcers during their recovery in the ICU. These ulcers had an atypical course and were exacerbated by surgical debridements. Accordingly, providers suspected PG, which was confirmed by the clinical evolution of the ulcers and biopsies taken from the wounds. To the best of the authors' knowledge, no previous articles have reported sacral pressure injuries associated with PG in patients with COVID-19. Providers should suspect PG in patients with COVID-19 who develop nonhealing pressure injuries.

A Study of the Impact of Cannabis on Doses of Discharge Antipsychotic Medication in Individuals with Schizophrenia or Schizoaffective Disorder.

Patients with schizophrenia or schizoaffective disorder have a high prevalence of comorbid cannabis use disorder (CUD). CUD has been associated with poorer outcomes in patients. We compared doses of antipsychotic medications at the time of discharge from hospital among inpatients with schizophrenia or schizoaffective disorder with or without concurrent cannabis use. We reviewed the medical records of patients (N = 8157) with schizophrenia or schizoaffective disorder discharged from the hospital between 2008 and 2012. The patients were divided into two groups; those with urine drug tests positive for cannabis and those negative for cannabis. Doses of antipsychotic medications were converted to chlorpromazine equivalents. Bivariate analyses were done with Student's t test for continuous variables and χ 2 test for categorical variables. Linear regression was carried out to adjust for potential confounders. Unadjusted analysis revealed that the cannabis positive group was discharged on lower doses of antipsychotic medication compared with the cannabis negative group (geometric mean chlorpromazine equivalent doses 431.22 ± 2.20 vs 485.18 ± 2.21; P < 0.001). However, the difference in geometric mean chlorpromazine equivalent doses between the two groups was no longer significant after adjusting for sex, age, race, and length of stay (geometric mean difference 0.99; 95 % CI 0.92-1.10). Though limited by lack of information on duration, amount and severity of cannabis use, as well as inability to control for other non-antipsychotic medications, our study suggests that cannabis use did not significantly impact on doses of antipsychotics required during the periods of acute exacerbation in patients with schizophrenia or schizoaffective disorder.

Weight and metabolic effects of CPAP in obstructive sleep apnea patients with obesity.

BACKGROUND: Obstructive sleep apnea (OSA) is associated with obesity, insulin resistance (IR) and diabetes. Continuous positive airway pressure (CPAP) rapidly mitigates OSA in obese subjects but its metabolic effects are not well-characterized. We postulated that CPAP will decrease IR, ghrelin and resistin and increase adiponectin levels in this setting. METHODS: In a pre- and post-treatment, within-subject design, insulin and appetite-regulating hormones were assayed in 20 obese subjects with OSA before and after 6 months of CPAP use. Primary outcome measures included glucose, insulin, and IR levels. Other measures included ghrelin, leptin, adiponectin and resistin levels. Body weight change were recorded and used to examine the relationship between glucose regulation and appetite-regulating hormones. RESULTS: CPAP effectively improved hypoxia. However, subjects had increased insulin and IR. Fasting ghrelin decreased significantly while leptin, adiponectin and resistin remained unchanged. Forty percent of patients gained weight significantly. Changes in body weight directly correlated with changes in insulin and IR. Ghrelin changes inversely correlated with changes in IR but did not change as a function of weight. CONCLUSIONS: Weight change rather than elimination of hypoxia modulated alterations in IR in obese patients with OSA during the first six months of CPAP therapy.

Birth Seasonality of Schizophrenia and Bipolar Disorder? A Review of Inpatient Records.

BACKGROUND: Numerous studies on seasonality of birth for mood disorders and schizophrenia have been published but findings are inconsistent 1. We aim to test the hypothesis of lack of seasonal birth differences in hospitalized Bipolar Disorder and Schizophrenia patients. METHODS: 15969 inpatient records in UTHealth Harris County Psychiatric Center between 2012-2014 were enrolled (HSC-MS-14-0274). Patients birth months that were diagnosed as Schizophrenia (n=4178) and Bipolar Disorder (n=5303) according to the DSM IV Criteria were tabulated including admitting diagnosis. Texas Birth statistics between 1903-1997 were obtained as control group (n= 17096471). RESULTS: There was no significant difference for winter births between schizophrenia patients and control group (P=0.738) and there was no significant difference for winter births between bipolar patients and control group either (P= 0.862). Mann Kendall Trend Analysis showed no significant trends of birth months for schizophrenia, bipolar and control groups. LIMITATIONS: The study limitations include being a retrospective study, inability to control for environmental factors, and recruiting from a single location. CONCLUSIONS: Our large sample showed no association between birth season or months with schizophrenia or bipolar disorder. Severe schizophrenia that requires admission may not be related with birth seasonality.

Olanzapine-Induced Hyponatremia Presenting with Seizure Requiring Intensive Care Unit Admission.

Rapid-onset hyponatremia is a rare, but potential, complication of olanzapine treatment. Hyponatremia, secondary to atypical antipsychotic use, has been reported in many case reports and is thought to be associated with a syndrome of inappropriate anti-diuretic hormone secretion (SIADH). Psychogenic polydipsia is a separate cause of hyponatremia, which is also seen in the psychiatric population, particularly in schizophrenia, and must be differentiated from SIADH. We report a case of sudden-onset hyponatremia resulting in seizure onset necessitating intensive care unit admission in a patient taking olanzapine during hospitalization in a psychiatric unit. Clinicians should be aware of the association between olanzapine and hyponatremia secondary to SIADH or psychogenic polydipsia. As in our case, the patient status may decline rapidly, resulting in seizure onset. Physicians should actively monitor patients taking antipsychotics for changes in serum sodium levels.

Race, History of Abuse, and Homelessness Are Associated With Forced Medication Administration During Psychiatric Inpatient Care.

OBJECTIVE: Although previous research has suggested that racial disparities exist in the administration of forced medication (FM) in psychiatric inpatients, data remain scarce regarding other contributing variables. Therefore, this study examined sociodemographic and clinical variables associated with FM administration in psychiatric inpatients. METHODS: Electronic medical records from 57,615 patients admitted to an academic psychiatric hospital between 2010 and 2018 were reviewed to identify patients who received FM. These records indicated that FM petitions were requested and approved for ∼6200 patients. Patients were excluded from the analysis if they met the following exclusion criteria: under 18 years of age, presence of intellectual/developmental disability, dementia, or other neurological condition, or primary diagnosis of a nonpsychiatric medical condition or a substance-induced mood or psychotic disorder. After data on those patients were excluded, the final sample included records from 2569 patients (4.5% of the total records) in which the administration of FM was petitioned for and approved. The FM group was compared with a control group of 2569 patients matched in terms of age, sex, and admission date (no-forced medication group; NFM) via propensity scoring matching. Group comparisons (FM vs. NFM group) examined sociodemographic factors (race, age, sex, living situation), clinical features (diagnosis, substance abuse, history of abuse), and outcomes (length of stay, readmission rate). Regression analyses examined the association between FM and sociodemographic, clinical, and outcome variables. RESULTS: Compared with the NFM group, the FM group contained significantly more African Americans (P<0.001), homeless individuals (P<0.001), and individuals with histories of abuse (P<0.001). Having received FM was a significant predictor of a longer length of stay (P<0.001) and higher readmission rates (P<0.001). DISCUSSION: These results suggest that FM is more likely to be instituted in psychiatric inpatients who are of a minority race (African American), are in a homeless living situation, and/or have a history of abuse. Moreover, FM may be associated with poorer clinical outcomes at least as measured by the length of stay and higher readmission rates. We discuss possible reasons for these results and the importance of culturally competent and trauma-focused care.

Feigning acute intermittent porphyria.

Acute intermittent porphyria (AIP) is an autosomal dominant genetic defect in heme synthesis. Patients with this illness can have episodic life-threatening attacks characterized by abdominal pain, neurological deficits, and psychiatric symptoms. Feigning this illness has not been reported in the English language literature to date. Here, we report on a patient who presented to the hospital with an acute attack of porphyria requesting opiates. Diligent assessment of extensive prior treatment records revealed thirteen negative tests for AIP.

The aesthetic applications of intense pulsed light using the Lumenis M-22 device.

BACKGROUND: Fifteen years have passed since the first Intense Pulsed Light (IPL) devices were introduced into the market. A variety of devices that use light energy for aesthetic puposes are currently manufactured by several companies, and newer devices offering improved performance and features are periodically being introduced. Herein we present our experience with the MP-22 device (Lumenis Ltd., Yokneam, Israel) for cosmetic treatment of benign skin lesions. PATIENTS AND METHODS: We collected patient data from all patients who received IPL and Nd:Yag laser treatments with the MP-22 over a one year period (Jan 2009-Jan 2010). The study group included 92 patients who were treated on the face, neck, trunk and hands. The main indications for treatment were lentigo and superficial vascular lesions. Patient age ranged from 16 to 72 years old, and 89 patients were female. Exclusion criteria for treatment were suspicion of skin cancer, isotretinoin treatment during the previous 6 months, and pregnancy. Satisfaction after treatment was evaluated by the patients on a scale ranging from 0 to 5, with 5 = excellent, 4 = very good, 3= good, 2= moderate improvement, 1= mild improvement and 0= no improvement. RESULTS: Ninety-three percent of the patients were satisfied (rating 3, 4 or 5 on the above scale). Ninety-five percent of the patients had one or two treatment sessions. Of the treatments, 82 were on the face, two on the neck, four on the trunk and 13 on the dorsal aspect of the hands. Minor side effects such as erythema for longer than 24 hours and facial edema for more than one day were reported by 9 patients. Major complications such as scars, hyperpigmentation or hypopigmentation were not recorded. The fluence delivered varied from 14-18 J/cm(2). CONCLUSION: IPL is an effective and safe method for skin treatments, namely removal of vascular and pigmented lesions.
